Prevalence of hypothyroidism in adults: An epidemiological study in eight cities of India

Ventricular tachycardia unveiling severe undiagnosed hypothyroidism

Hypothyroidism is typically associated with bradyarrhythmias, but can rarely precipitate life-threatening ventricular arrhythmias. We present a case of severe hypothyroidism manifesting as polymorphic ventricular tachycardia (VT). A previously healthy woman in her early 50s presented with an acute onset of breathlessness and on examination had hypotension and tachycardia. ECG revealed polymorphic VT, promptly terminated by defibrillation using 200J biphasic shock. Investigations uncovered severe primary hypothyroidism (thyroid-stimulating hormone: 142 mIU/l) and left ventricular (LV) dysfunction with ejection fraction (EF) of 35%. Coronary angiogram was normal. Treatment with levothyroxine and standard heart failure therapy was initiated. In conclusion, at 3- and 6-month follow-ups, the patient remained asymptomatic and had no episodes of tachyarrhythmias without antiarrhythmic drugs, and her LV function normalized (EF: 55%). This case highlights the importance of considering hypothyroidism in patients presenting with unexplained ventricular arrhythmias.

Effects of Six Months of Levothyroxine Therapy on Sympathovagal Imbalance and Cardiometabolic Profile in Overt Hypothyroid Patients

INTRODUCTION

Hypothyroidism, a common endocrine disorder, is linked to cardiovascular risks arising from autonomic imbalance and metabolic dysregulation. While overt hypothyroidism (OH) manifests distinct thyroid hormone abnormalities, subclinical hypothyroidism (SCH) presents milder hormonal changes. Levothyroxine therapy is widely used for thyroid function restoration, but its long-term effects on autonomic and cardiovascular health in OH remain understudied. This study investigates the therapeutic effects of six months of levothyroxine treatment on autonomic function and metabolic parameters in OH patients.

MATERIALS AND METHODS

A follow-up study was conducted on OH patients receiving levothyroxine therapy. Participants with confounding cardiovascular comorbidities were excluded. Clinical assessments included autonomic function tests, metabolic profiling (lipid and thyroid parameters), and inflammatory/oxidative stress markers. Comparative analyses were performed against healthy controls.

RESULTS

Levothyroxine therapy effectively restored thyroid hormone levels in OH patients. Autonomic function tests demonstrated improved parasympathetic modulation and partial sympathovagal balance recovery, though residual autonomic irregularities persisted. Lipid profiles showed marked improvement but did not fully normalize compared to controls. Inflammatory and oxidative stress markers decreased significantly post-therapy, yet remained elevated relative to healthy individuals. Statistical modeling identified oxidative stress as a key contributor to autonomic dysfunction.

DISCUSSION

While levothyroxine normalized thyroid function and improved autonomic balance, incomplete resolution of metabolic and inflammatory abnormalities suggests persistent cardiovascular risks in OH patients after six months of therapy. The findings highlight the need for extended treatment durations to achieve comprehensive cardiovascular risk mitigation.

CONCLUSION

Despite therapeutic benefits, OH patients retain residual cardiovascular risks post-levothyroxine therapy, necessitating long-term monitoring. Future research should investigate optimal treatment durations and adjunct therapies to address persistent autonomic and metabolic dysfunction in this population.

Relationship between thyroid-stimulating hormone levels and the severity of vitamin D deficiency by age group

OBJECTIVE

Researchers have long been captivated by the complex molecular interactions between vitamin D and the thyroid gland. Hypothyroidism affects 2% to 4% of women of reproductive age and can impact fertility through anovulatory cycles, luteal phase defects, hyperprolactinemia, and sex hormone imbalances. This study investigated the relationship between thyroid disease and the severity of vitamin D deficiency across different age groups.

METHODS

A retrospective study was conducted of 286 patient samples from individuals aged 18 to 60 years who were processed in the clinical biochemistry laboratory of our hospital. Samples were tested for thyroid-stimulating hormone (TSH) and vitamin D (specifically, vitamin D3) levels. The study samples were categorized into four clinically relevant groups based on TSH levels and into three groups based on serum 25-hydroxyvitamin D (25(OH)D) levels.

RESULTS

Most of the samples were from female patients (n=269), and the most common age group was 18 to 35 years (n=191, 66.78%). Subclinical hypothyroidism was identified in 120 patients, while vitamin D deficiency was present in 237 (82.87%) participants. A significant association was observed between vitamin D deficiency and the presence of thyroid disorders. Additionally, a significant negative correlation was found between TSH and vitamin D levels. Polycystic ovary syndrome was noted in 103 female patients (36.01%).

CONCLUSION

TSH and 25(OH)D levels should be screened in all women of reproductive age, not just those in high-risk groups, as subclinical and occult hypothyroidism may otherwise go undiagnosed. Furthermore, TSH should be considered the primary screening test.

Prevalence and associated factors of anxiety and depression among patients with hypothyroidism in Southern Iran

PURPOSE

Depression and anxiety are the main disorders in patients suffering from hypothyroidism. These disorders can lead to increased patient suffering. Since hypothyroidism is one of the most prevalent endocrine diseases, controlling the metabolic variables that increase the severity of anxiety and depression is important. This study aimed to assess the prevalence of anxiety and depression and to identify their associated factors, including metabolic variables, among people with hypothyroidism.

PATIENTS AND METHODS

We performed a cross-sectional study of 1,600 patients with hypothyroidism in Kerman, the southern part of Iran. The prevalence of depression and anxiety was estimated using the Beck Depression Inventory and the Hamilton Anxiety questionnaires, respectively. First, univariate logistic regression was performed. Factors whose P-values were smaller than 0.2 in univariate logistic regression were included in multiple logistic regression for confounder adjustments. The analysis was performed using SPSS version 20.

RESULTS

The rates of depression and anxiety were 59% (95% CI: 53.18-62.11) and 63% (95% CI: 58.42-67.22), respectively. Factors found to be independently associated with anxiety were high TSH, high LDL, high TG, high FBS, high TGAb, high TPoAb, high TC, and hypertension. For depression, high TSH, high LDL, high TG, high FBS, high TC, and hypertension were identified. High TGAb and high TPoAb were independently associated with anxiety but not with depression.

CONCLUSIONS

Study findings revealed that a large proportion of patients with hypothyroidism suffer from depression and anxiety. This study also identified factors associated with these disorders. Controlling some metabolic variables may decrease the prevalence and severity of these disorders, help patients with better treatment, and improve their quality of life.

Correlation of Residual Symptoms With Triiodothyronine (T3) in Patients Treated for Hypothyroidism

Background Despite the time-honored concept that a normal serum thyroid-stimulating hormone (TSH) indicates that there is euthyroidism in all tissues, there is accumulating evidence questioning this notion. This could explain why a subset of patients remain symptomatic despite treatment with levothyroxine. This study will help identify patients with residual symptoms through questionnaires and the relation of the test scores (obtained from these questionnaires) to serum triiodothyronine (T3) levels. Methods A total of 108 hypothyroid patients on levothyroxine supplementation who are biochemically euthyroid were included. Residual symptoms on treatment and symptom questionnaires (thyroid symptom questionnaire (TSQ), general health questionnaire (GHQ-12), Hospital Anxiety and Depression Scale (HADS) and Epworth Sleepiness Score (ESS)) were administered to subjects and their scores correlated with T3 values. Results A total of 108 subjects, comprising 98 females (90.7%) and 10 males (9.3%), with a mean age of 39.19 years (± 13.18 years), were analyzed in this study. The majority of the participants (75.9%, n=82) reported experiencing at least one symptom. The most prevalent symptom was dry skin, reported by 44.4% (n=48) of the subjects, followed by weight gain, which affected 30.6% (n=33) of the participants. Statistical analysis revealed significant inverse correlations between all assessed scores - TSQ, GHQ-12, HADS, and ESS - with T3 values. The correlation coefficients and corresponding p-values indicate significant relationships between thyroid function and psychological well-being in the studied population. The following correlation coefficients (r values) were obtained: TSQ, r=-0.331 (p = 0.001); GHQ-12, r=-0.292 (p = 0.002); HADS-A, r=-0.318 (p = 0.001); HADS-D, r = -0.233 (p = 0.015); and the ESS, r=-0.205 (p = 0.034). These findings highlight the notable impact of thyroid function on mental health outcomes. Conclusions Treatment satisfaction remains suboptimal for patients with residual symptoms of hypothyroidism. TSQ especially seems to be a useful tool to recognize these residual symptoms. The further use of this tool to identify patients with residual symptoms may enable future studies to test the role of oral T3 in such patients given the strong negative correlation.

S, S. M, S. Sundarakumar J, Stezin A, Issac TG. Prevalence of hypothyroidism in older adults and its association with cognition: a cross-sectional study from a South Indian ageing urban cohort

The study conducted on a South Indian urban cohort aimed to emphasize the prevalence and patterns of hypothyroidism and its association with cognition among individuals aged 45 years and above. A cross-sectional design was adopted, utilizing data from the Tata Longitudinal Study of Aging cohort, comprising 1201 non-demented participants in Bangalore, South India. The study contains detailed clinical assessments, including medical history, physical examination and cognitive tests such as the COGNITO battery, Hindi Mental State Examination and Addenbrooke's Cognition Examination III. Biochemical tests were utilized to quantify plasma levels of thyroid-stimulating hormone, triiodothyronine and thyroxine. Participants were categorized based on medication history and thyroid hormone levels. The study findings showed a 17.69% prevalence of hypothyroidism, with 6.22% being classified as overt hypothyroidism and 93.78% as subclinical hypothyroidism. The prevalence was significantly higher in females compared with males (P = 0.043). Individuals with hypothyroidism are more frequently diagnosed with mild cognitive impairment than people with euthyroid (P = 0.008). Furthermore, on the classification based on thyroid medication history, the ineffective treatment group performed poorer in Addenbrooke's Cognition Examination III fluency (P = 0.006), auditory attention (P = 0.001) and form matching (P = 0.024) tasks compared with the adequately treated group. The partially treated group performed poorer in visual attention (P = 0.005) and vocabulary (P = 0.043) compared with the effectively treated group. The study identified a notable prevalence of hypothyroidism in the cohort, with females exhibiting a higher prevalence. Our study suggests that the timely management of thyroid disorders with medications is crucial not only to prevent hormonal imbalances but also to improve cognitive functioning.

Effect of Pre- and Postprandial Plasma Glucose Levels on Thyroid Hormones: A Cross-Sectional Study

Background There is not much data regarding the effect of plasma glucose on thyroid hormones. Currently, there is no consensus regarding the timing of blood sample collection for thyroid hormones. Evaluation of the correlation between plasma glucose and thyroid hormones may enhance pathophysiological understanding of postprandial thyroid stimulating hormone (TSH) decline. Objectives To study the effect of pre-and postprandial plasma glucose levels on thyroid hormones. Methodology A cross-sectional study was done among participants aged 18 years and above after obtaining informed consent. Venous blood samples for fasting and postprandial plasma glucose, fasting, and postprandial thyroid profile ((FT3), (FT4), and TSH) were collected. The association was studied using the t-test and chi-square test between groups, while correlation using Pearson's correlation coefficient. A p-value of <0.05 was considered statistically significant. Results Among the 197 participants, 126 (64%) were female and 71 (36%) were male. The mean (± S.D.) of age was 43.74 (± 12.62) years. Mean (± S.D.) postprandial TSH (4.31 μU/ml (± 7.79)) and free T3 (285.52 pg/dl (± 32.46)) were less than the fasting values (4.99 μU/ml (± 7.78)) and (295.84 pg/dl (± 32.56)). The mean (± S.D.) of both fasting and postprandial TSH and free T4 were less in the high plasma glucose group compared to the normal plasma glucose group (fasting state p-values 0.005, <0.0001 & postprandial state p-values 0.016, <0.0001). The correlation between fasting plasma glucose and fasting TSH values (Pearson correlation; r=-0.18; p-value 0.232) was observed across all the plasma glucose ranges. Conclusion There is a significant postprandial decline in TSH levels than the fasting TSH, indicating that there is a plasma glucose-mediated reduction in TSH values.

Prevalence of abnormal thyroid function test in adults attending primary care setting in the year 2022 in the Kingdom of Bahrain

Background

Thyroid disease is known to be one of the most common endocrine diseases globally and has serious health implications if left untreated.

Objective

This study aimed to gain a better understanding of common thyroid diseases and to explore the associated risk factors in the Kingdom of Bahrain.

Methods

A case-control study was carried out after obtaining all thyroid stimulating hormone (TSH) results done in a primary healthcare setting from January 1, 2022 to December 31, 2022 from the Health Information Department. In total, 500 participants were randomly selected from each group: the abnormal thyroid test group (cases) and the normal thyroid test group (controls). Participants were interviewed using a structured list of associated risk factors with the following sections: sociodemographic characteristics, comorbidities, family history of thyroid disease, BMI, previous radiation therapy, and certain medications.

Results

The prevalence of abnormal thyroid tests was found to be 11%. Cases were categorized into four groups: hyperthyroidism (26.4%), hypothyroidism (64.6%), hyperthyroidism (4.5%), and subclinical hypothyroidism 13 (4.5%). The results showed significant differences between case and control in the following risk factors: female sex, increasing age, BMI, dyslipidemia, family history of thyroid disease, and previous radiation therapy (P = <0.05).

Conclusion

In summary, the high prevalence of abnormal thyroid results highlights the need for an organized national screening program for individuals at average risk for developing thyroid disease.

Hypothyroidism in Metabolic Syndrome

INTRODUCTION

Metabolic syndrome (MetS) and hypothyroidism are well-established forerunners of atherogenic cardiovascular disease (CVD). It is possible that patients suffering from both these disease entities may have a compounded risk. This study aimed at determining the prevalence of hypothyroidism in MetS.

MATERIALS AND METHODS

This cross-sectional study was conducted from September 2017 to August 2018 in the department of medicine at a tertiary care hospital in Northern India. Ethical approval was obtained from the institutional ethical committee. The study subjects consisted of 157 patients with MetS, the diagnosis of which was based on the International Diabetes Federation criteria. After a detailed history and physical examination, relevant investigations including complete thyroid profile were done. The data were analyzed using appropriate statistical tests (P < 0.05).

RESULTS

In our study, the age of subjects ranged between 14 and 92 years, with a mean ± standard deviation of 48.1 ± 17.01 years. There were more females than males with a male-to-female ratio of 1:1.3. The prevalence of hypothyroidism was 46.5%. Hypothyroidism was more common in females (58.9%) as compared to males (41.1%). Patients with hypothyroidism had significantly higher body weight and body mass index (BMI) in comparison to euthyroid patients. The rest of the anthropometric parameters were comparable. Waist circumference and BMI of overt hypothyroid patients were found to be higher as compared to subclinical hypothyroid patients. Total cholesterol and triglyceride were significantly higher (P = 0.001 and P < 0.001, respectively), while high-density lipoprotein levels were significantly lower in patients with hypothyroidism than the euthyroid group (P < 0.001).

CONCLUSION

Hypothyroidism, especially subclinical hypothyroidism, is a common endocrine disorder in patients with MetS. As MetS and hypothyroidism are independent risk factors for CVD, hence there is a need for screening for hypothyroidism and the treatment of the same can be beneficial in reducing the cardiovascular morbidity and mortality in patients with MetS.

Preoperative Preparation in Hyperthyroidism and Surgery in the Hyperthyroid State

Hyperthyroidism is a clinical condition that develops due to the excessive production and secretion of thyroid hormones by the thyroid gland, leading to an elevated concentration of thyroid hormones in tissues. Hyperthyroidism is characterized by low TSH and elevated T3 and/or T4, with the most common causes being Graves' disease, toxic multinodular goiter, and solitary toxic adenoma. T3 is the peripherally active form of thyroid hormone, affecting nearly each tissue and system. The most prominent aspects of hyperthyroidism are related to the cardiovascular system. The treatment of hyperthyroidism includes three options: antithyroid drugs (ATDs), radioactive iodine therapy (RAI), and surgery. Among these treatment modalities, surgery is considered as the most effective one. For patients who are candidates for surgery, preoperative preparation is required to ensure that the thyroidectomy can be performed under optimal conditions. Preoperative preparation should be a combination therapy aimed at preventing the synthesis, secretion, and peripheral effects of thyroid hormones from the thyroid gland. Medications that can be used in this treatment include thionamides, beta-blockers, iodine, corticosteroids, cholestyramine, perchlorate, lithium, and therapeutic plasma exchange. These treatment options can be combined based on the patient's condition. While it is recommended that patients be made euthyroid through preoperative antithyroid treatment to prevent the feared complication, which is the thyroid storm, the supporting evidence is limited. Preoperative treatment does not prevent against thyroid storm whether the patient is euthyroid or hyperthyroid during surgery. Whether surgery should be delayed until biochemical euthyroidism is achieved in hyperthyroid patients remains a topic of debate. Recent studies suggest that thyroidectomy can be safely performed during the hyperthyroid phase by experienced anesthesiologists and surgeons without precipitating thyroid storm or increasing intraoperative and postoperative complications. Although achieving the euthyroid state before surgery is ideal in hyperthyroid patients, it is not always possible. Factors such as allergies to medications, drug side effects, treatment-resistant disease, patient noncompliance, and the urgency of definitive treatment are critical in determining whether hyperthyroidism can be controlled preoperatively. When surgery is necessary in hyperthyroid patients without achieving euthyroidism, the patient's overall condition and comorbidities should be evaluated together by the anesthesiologist, surgeon and endocrinologist, with particular attention to stabilizing the cardiovascular system. We believe that in hyperthyroid patients who are cardiovascularly stable during the hyperthyroid phase, thyroid surgery may not need to be delayed and can be performed safely.

A Randomized Clinical Trial Comparing 2 Levothyroxine Regimens During Ramadan Fasting in Thyroidectomized Patients

Context

For Muslim patients on levothyroxine (L-T4) therapy, the best approach for L-T4 intake during Ramadan fasting remains unclear.

Objective

We compared 2 practical approaches for L-T4 intake during Ramadan.

Methods

We randomly assigned 69 patients (21 males, 48 females, median age 44 years) with differentiated thyroid cancer (DTC) who underwent thyroidectomy in the past and are on stable LT4 doses to 2 arms. Arm A (33 patients) ingested their pre-Ramadan L-T4 dose at the evening meal and ate immediately. Arm B (36 patients) increased their pre-Ramadan dose by 25 µg if their regular L-T4 dose was ≤150 µg/day or by 50 µg if their pre-Ramadan dose was >150 µg/day and ate immediately.

Results

At the beginning of Ramadan (baseline), the median thyrotropin (TSH) level and the numbers of patients in euthyroidism, subclinical hyperthyroidism (Shyper), or subclinical hypothyroidism (Shypo) were comparable between the 2 arms (P = .69 and P = .65, respectively). At the end of Ramadan, in arm A there were 17 (51.5%), 3 (9.1%), and 13 (39.4%) patients in euthyroidism, Shyper, and Shypo compared with 17 (47.2%), 14 (38.9%), and 5 (13.9%) patients, respectively, in arm B (P = .005). The mean ± SD TSH levels in arms A and B at the end of Ramadan were 5.6 ± 6.0 mU/L and 1.67 ± 2.6 mU/L, respectively (P = .0001).

Conclusion

No overt thyroid dysfunction developed but there were more cases of Shypo in arm A and Shyper in arm B. Arm B achieved desirable levels of TSH (normal or slightly suppressed) in 86% of cases and might be a preferable approach, especially for patients who need TSH suppression (eg, DTC).

A Study of Non-alcoholic Fatty Liver Disease in Patients With Hypothyroidism: A Cross-Sectional Study in a Tertiary Care Hospital

Background Hypothyroidism occurs when the thyroid gland is underactive and fails to produce sufficient thyroid hormones. It can affect multiple organs including the heart, brain, liver, kidneys, and reproductive system, leading to symptoms such as fatigue, cognitive impairment, elevated cholesterol, fluid retention, fatty liver, and menstrual irregularities. Given the higher prevalence of fatty liver disease in patients with hypothyroidism, it is important to evaluate the need for routine screening for fatty liver in these patients. Materials and methods This observational, cross-sectional study was conducted at Dr. D. Y. Patil Medical Hospital, Pune, Maharashtra, India, from October 2022 to June 2024. The study included 60 patients aged over 12 years who were known or recently diagnosed with hypothyroidism. Patients with type 2 diabetes mellitus, pregnant women, or those with chronic liver disease were excluded. Data collected included physical examination findings and laboratory test results. Fatty liver was diagnosed using magnetic resonance elastography. Statistical analysis was performed using IBM SPSS statistics for Windows, version 20 (IBM Corp., Armonk, New York). The statistical significance of parametric data was evaluated using the Chi-square test. A p-value less than 0.05 and a confidence interval of 95% were considered statistically significant. Result The study population had an average age of about 45 years, with most participants aged between 40 and 49 years. The majority of the participants were female, making up over 83% of the group, while males constituted about 17%. The most commonly reported symptom was weight gain, followed by constipation and fatigue. For individuals with fatty liver, the average thyroid-stimulating hormone (TSH) level was notably higher compared to those without fatty liver. Additionally, low-density lipoprotein (LDL) levels were higher in individuals with non-alcoholic fatty liver disease (NAFLD) compared to those without. Both TSH and LDL levels showed a statistically significant association with the occurrence of NAFLD. Conclusion Hypothyroidism was more prevalent in females and in the age group 40-49 years. There was a statistical significance between TSH and the occurrence of NAFLD. In this study, statistical significance was also found between LDL and the occurrence of NAFLD.

Evaluating the Spectrum of Sleep Abnormalities in Patients With Primary Hypothyroidism

Introduction and aim: Primary hypothyroidism is a common endocrine disorder. While thyroid dysfunction is recognized for impacting numerous bodily systems, the connection between thyroid disorders and sleep function remains unclear. Since sleep disorders seldom manifest as the sole presenting symptom of thyroid dysfunction, it is crucial to examine the interplay between thyroid function and sleep when implementing a comprehensive treatment approach for these individuals. This study aimed to assess sleep dysfunction in patients with primary hypothyroidism using validated questionnaires.

METHOD

This cross-sectional study included 81 participants attending the endocrinology outpatient department. The participants included those with both overt and subclinical primary hypothyroidism who were drug-naive or had a thyroid-stimulating hormone (TSH) level >4.5 µIU/L while on treatment. The study subjects were assessed based on various validated questionnaires for sleep disturbance.

RESULTS

The study predominantly comprised 64 (79%) female participants. Overall, poor sleepers in subclinical and overt hypothyroidism were 66.7 and 60.8%. The Berlin Risk Score Questionnaire showed the occurrence of sleep apnea to be 26.7% and 27.5% in subclinical and overt groups, respectively. However, the occurrence of sleep dysfunction did not correlate with TSH values alone.

CONCLUSION

Our findings demonstrate that sleep dysfunction is prevalent in patients with both overt and subclinical primary hypothyroidism. Furthermore, the severity of sleep disruption appears independent of the degree of thyroid dysfunction.

Prevalence of hypothyroidism among postmenopausal women in an urbanised village of northern India: A cross-sectional study

Introduction

Hypothyroidism is among the most prevalent endocrine disorders worldwide. Its risk increases with menopause. The prevalence of hypothyroidism among menopausal women in India is unknown, as conclusive data are scarce. The present study was conducted to find out the prevalence of hypothyroidism among menopausal women in Delhi, India, and study the socio-demographic factors associated with it.

Methods

This was a cross-sectional community-based study done among 282 menopausal women in an urbanised village in Delhi, India. Women with a previously known history of diagnosed thyroid disorders were also included in the study. Informed written consent was obtained from all participants. A socio-demographic profile was gathered by questionnaire and blood samples were collected and analysed for thyroid hormone levels.

Results

The mean age of study participants was 51.1 years. The prevalence of hypothyroidism among postmenopausal women was 27.3% (77) with 19.9% (56) previously diagnosed and 7.3% (21) diagnosed by the present study. Out of 56 previously diagnosed hypothyroid study participants, only 26 (46.4%) participants had thyroid hormones in a normal range. Age, socio-economic status and literacy status were found to be significantly associated with hypothyroidism.

Conclusion

About three postmenopausal women out of 10 were found to be hypothyroid. Nation-wide data were required to estimate the true burden of thyroid disorders in this population. The prevalence increased with age underscoring the need for further research to have conclusive evidence regarding this association. Hypothyroid women who are on treatment should undergo regular evaluation of thyroid hormones so that appropriate dose adjustments can be made for pharmacological therapies.

L, P. V. Cut-off values of coronary risk factors in women with hypothyroidism

Women with hypothyroidism are at higher risk of cardiovascular diseases and the consequent mortality. It is not known whether cut-off values of coronary risk factors in women with hypothyroidism are the same as healthy women. This may help to initiate interventions as early to prevent cardiovascular mortality. Therefore, this study was conducted to determine the cut-off values of coronary risk factors in women with hypothyroidism. One hundred women patients with hypothyroidism were compared with 100 healthy controls. Significantly higher mean body mass index (BMI), waist circumference (WC), triglycerides and low-density lipoprotein cholesterol (LDL-C) were observed in women with hypothyroidism than without it. All variables showed an area under curve (AUC) value of >0.6 in receiver operator characteristic curve (ROC) analysis, and similar to healthy women.

Determination of Serum Zinc and Phosphorus Levels in Patients with Hypothyroidism

Various studies reported that serum zinc (Zn) and phosphorus (P) levels altered in patients with hypothyroidism and vice versa, but results were found inconsistent. It was aimed to find the association between serum Zn and P in patients with hypothyroidism. In this case-control study, a total of 100 subjects (50 newly diagnosed patients of hypothyroidism and 50 controls) were enrolled aged between 25 and 60 years. Biochemical parameters such as thyroid profile, serum Zn, and P were estimated in each subject. A p < 0.05 was considered statistically significant. The mean level of body mass index (BMI), thyroid-stimulating hormone (TSH), and serum P was found significantly elevated in cases compared to controls (p < 0.001). However, the mean level of total triiodothyronine (T3), thyroxine (T4), and serum Zn was found significantly reduced in cases compared to controls (p < 0.001). The serum Zn has shown a significant negative correlation with T3 and BMI among cases (r =  - 0.313 p < 0.05, r =  - 0.338 p < 0.05, respectively). However, serum P has shown a significant positive correlation with TSH and BMI among cases (r = 0.310 p < 0.05, r = 0.449 p < 0.01, respectively). Regression analysis indicated that serum Zn significantly predicted hypothyroidism (p < 0.00). Similarly, serum P significantly predicted hypothyroidism (p < 0.007). Results showed that serum Zn levels were significantly reduced and serum P levels were significantly elevated in cases compared to controls. The serum Zn and serum P both significantly associated with hypothyroidism.

Correlation between estradiol-to-testosterone ratio and thyroid peroxidase antibody positivity in men with treatment-naïve primary hypothyroidism or euthyroidism

Objective

Thyroid diseases pose a substantial socioeconomic burden globally. The aim of this study was to evaluate the correlation between estradiol-to-testosterone (E2/T) ratio and thyroid peroxidase antibody (TPOAb) positivity in male patients with hypothyroidism or euthyroidism.

Subjects and methods

Cross-sectional observational study including 115 male patients with hypothyroidism or euthyroidism. The patients were divided into two groups based on positive or negative TPOAb results, with TPOAb positivity defined by a serum TPOAb value ≥ 35 IU/mL.

Results

Patients with positive TPOAbs, compared with those with negative TPOAbs, had a higher prevalence of goiter and obesity and higher levels of total cholesterol, triglycerides, and low-density lipoprotein (LDL) cholesterol. The median estradiol level was higher, and the median total testosterone and sex-hormone binding globulin (SHBG) levels were lower in the TPOAb-positive versus the TPOAb-negative group (p < 0.001). In subgroup analysis including only patients with hypothyroidism (n = 80), the median E2/T ratio was higher in the TPOAb-positive group (p = 0.016). The prevalence of TPOAb positivity increased with the increase in E2/T ratio quartiles, from 37.9% in the lowest quartile to 96.2% in the highest quartile (p value for trend across all quartiles < 0.001). On adjusted multivariate analysis, the E2/T ratio emerged as an independent predictor of TPOAb positivity. An E2/T ratio cutoff value of 6.565 x10-3 demonstrated the best diagnostic accuracy, with a sensitivity of 78.2% and specificity of 67.6%.

Conclusion

The present study provides insights into the role of the E2/T ratio as a predictor of thyroid disorders.

Association of Non-High-Density Lipoprotein Cholesterol With Cardiometabolic Risk Factors in Patients With Hypothyroidism

INTRODUCTION

Non-high-density lipoprotein cholesterol (non-HDL-C) levels can increase the cardiometabolic risk factors in patients with hypothyroidism, but the findings across studies have not been consistently conclusive. The aim of this study was to find the association between non-HDL-C and cardiometabolic risk factors in patients with hypothyroidism.

MATERIAL AND METHODS

In this case-control study, a total of 120 subjects among which 60 diagnosed hypothyroidism patients and 60 age-matched healthy controls were enrolled, aged 30-65 years. Body mass index (BMI), waist circumference (WC), and systolic and diastolic blood pressures (SBP and DBP) were measured. Thyroid-stimulating hormone (TSH), triiodothyronine (T3), thyroxine (T4), fasting blood sugar (FBS), total cholesterol (TC), triglyceride (TG), and high-density lipoprotein cholesterol (HDL-C) were estimated. Low-density lipoprotein cholesterol (LDL-C), very low-density lipoprotein cholesterol (VLDL-C), and non-HDL-C were calculated. A p-value of <0.05 was considered statistically significant.

RESULTS

Mean of BMI, WC, FBS, TSH, TC, TG, non-HDL-C, LDL-C, VLDL-C, SBP, and DBP were significantly elevated in cases compared to controls (p<0.001). However, the mean of T3, T4, and HDL-C were significantly reduced in cases compared to controls (p<0.001). Non-HDL-C has shown a significant positive correlation with age (r=0.345, p<0.01), TC (r=0.451, p<0.01), TG (r=0.269, p<0.05), LDL-C (r=0.402, p<0.01), and VLDL-C (r=0.269, p<0.05) among cases. However, non-HDL-C has shown a significant negative correlation with HDL-C (r=-0.330, p<0.05) among cases. Non-HDL-C significantly predicted cardiometabolic risk in patients with hypothyroidism (F(13,46)=3.500, p<0.001).

CONCLUSION

Non-HDL-C has shown a significant association with age and lipid abnormalities in patients with hypothyroidism. Non-HDL-C significantly predicts cardiometabolic risk factors in patients with hypothyroidism.

Efficacy of Standardized Yoga Asanas as Add-on Therapy in the Management of Hypothyroidism: A Randomized, Open-label, Controlled Clinical Study

Background

Hypothyroidism is an endocrine disorder in which the thyroid gland does not produce an adequate amount of thyroid hormones. This study aimed to determine the efficacy of yoga asanas as an add-on therapy for the management of hypothyroidism.

Materials and Methods

For this interventional clinical study, a total of 450 study participants were screened for eligibility. Out of this, 170 study participants were found fit for preliminary eligibility following stringent inclusion and exclusion criteria. Further, 58 participants were excluded before randomization. A total of 112 hypothyroidism patients (57 in the control group and 55 in the yoga group) participated in this study. The study participants were further followed up for 8 weeks in both the yoga practice (yoga+ standard care of treatment) and control group (standard care of treatment only). The markers of oxidative stress, inflammation, and thyroid hormones were assessed at baseline and after 8 weeks of follow-up/intervention.

Results

After 8 weeks, the study participants in yoga group showed a significant reduction in serum thyroid-stimulating hormone and malondialdehyde levels as compared to baseline (P < 0.05). There was also a positive trend of improvement in other oxidative markers (catalase, superoxide dismutase, and glutathione), and a significant reduction in interleukin-6 levels (P < 0.05) was found in the yoga group as compared to the baseline. However, there was no significant change found in the control group of subjects.

Conclusion

Frequent yoga practice can be an effective lifestyle intervention for hypothyroidism, reducing oxidative stress, inflammation, and potentially improving overall well-being.

A critical evaluation of pictogram based patient information leaflet on hypothyroidism patients with metabolic syndrome: a visual approach to enhance health literacy

INTRODUCTION

Hypothyroidism is a condition with an underactive thyroid gland. Since thyroid hormones play a significant role in metabolism, hypothyroidism is often associated with metabolic syndrome. Thus, the patient's awareness regarding metabolic syndrome is crucial.

OBJECTIVES

To develop and evaluate a Pictogram-based Patient Information Leaflet (P-PIL) for hypothyroidism with metabolic syndrome.

MATERIALS AND METHODS

This is a quasi-experimental study without a control group. The P-PIL was developed and validated using the Lawshe Method, translated, and evaluated with 72 patients (24 patients each for English and regional languages, Kannada and Malayalam).

RESULTS

The leaflet's Flesch Reading Ease (FRE) and Flesch-Kincaid Grade Level (FKGL) scores were 62.0 and 7.1, respectively. The Baker Able Leaflet Design (BALD) index of English, Kannada, and Malayalam versions of the P-PIL were 28, 27, and 27, respectively. The user testing of the P-PIL was assessed in 72 patients. The overall mean knowledge assessment scores significantly improved from 52.92 ± 6.90 to 77.92 ± 9.31. The majority of patients, precisely 84.72%, expressed a positive opinion regarding the design and layout of the P-PIL.

CONCLUSION

The evaluation results strongly suggest that this P-PIL can be an effective educational tool for hypothyroidism patients with metabolic syndrome.

The thyroid-pericardium connection: Unveiling the influence of hypothyroidism severity on pericardial effusion in South Gujarat's patient population-A cross-sectional study

Context

Hypothyroidism and pericardial effusion are two conditions that are associated with previous research. Nevertheless, the correlation between the severity of hypothyroidism and the occurrence of pericardial effusion remains uncertain.

Aims

1. To explore and examine the association between the severity of hypothyroidism and the occurrence of pericardial effusion. 2. To compare clinical characteristics and demographic factors with varying degrees of hypothyroidism severity and pericardial effusion.

Settings and Design

Tertiary care hospital and cross-sectional study using a pretested, semistructured questionnaire and echocardiography.

Method and Material

The cross-sectional study encompassed a cohort of 60 patients diagnosed with hypothyroidism.

Statistical Analysis Used

Epi-info version 7.0 and Open epi version 3.1, Chi-square, mean, and standard deviation were used.

Results

There were 16 male participants, accounting for 26.7% of the total, and 44 female participants, constituting 73.3% of the cohort. The participants' average age was 35.5 years. Based on TSH levels, the severity of hypothyroidism in the study was classified into three categories: mild (33.4%), moderate (43.3%), and severe (23.3%). The most common symptoms were lethargy, weight gain, and cold intolerance. Also, an association between the severity of hypothyroidism and pericardial effusion was noted.

Conclusion

This research established a noteworthy correlation between hypothyroidism severity and pericardial effusion incidence that is statistically significant. Nevertheless, no significant associations were detected with demographic factors or pulse rate. These results underscore the significance of monitoring and addressing pericardial effusion in patients with moderate-to-severe hypothyroidism. Further investigations are warranted to extend these findings.

Correlation Between Hypothyroidism and Gallstone Disease in Central India

Introduction The decreased thyroid-stimulating hormone (TSH) levels affect almost every nucleated cell in our body, which directly affects the basal metabolic rate (BMR). It tends to affect multiple organ systems in the human body. In recent times, there have been changes in lifestyle and the consumption of processed foods has increased. Thus, cholelithiasis and hypothyroidism are being encountered frequently, even in rural populations. In recent times, the overt clinical presentation of hypothyroidism is rare due to early diagnosis and treatment of the subclinical hypothyroidism state itself. Aim The aim is to determine the correlation between cholelithiasis and hypothyroidism. Methods This was a cross-sectional study done on the patients presenting to the surgical department at Acharya Vinoba Bhave Rural Hospital affiliated to Jawaharlal Nehru Medical College, Sawangi (Meghe), Wardha, Maharashtra, India between the duration from December 2020 to December 2022, having gallstone disease or with symptoms suggestive of gall bladder stones. The admitted patients were then evaluated for hypothyroidism by thyroid profile tests, and the results were documented. Using the collected data, factors such as clinical spectrum, correlation between cholelithiasis and hypothyroidism, relation with the demographic data, and body mass index (BMI) were studied. Results A total of 52 gallstone patients were included in the study. A greater number of patients were found to be above the age of 40 years (82.7%), with female preponderance (61.5%). More patients with cholelithiasis were from the group with having BMI more than normal (57.6%). More patients having both cholelithiasis and hypothyroidism were also from the group with having BMI more than normal. Most symptomatic patients complained of pain in the right hypochondriac region (88.5%). Of these 52 patients, nine (17.3%) were found to have hypothyroidism (seven were subclinical, two patients had overt clinical symptoms and signs) and the remaining 43 patients were euthyroid. Conclusions Our study supports that there is a correlation between cholelithiasis and hypothyroidism. Out of all the 52 patients, nine had hypothyroidism, seven were subclinical, and two had overt symptoms. Thus, we conclude that there is a correlation between cholelithiasis and hypothyroidism.

A Cross-Sectional Study on Motor and Sensory Nerve Functions in Women Newly Diagnosed and Untreated for Hypothyroidism in a Tribal Area of Odisha, India

Introduction: Altered levels of thyroid hormones can impact various body systems, including the nervous system. Hypothyroidism may disrupt nerve conduction due to pathophysiological changes associated with hormone deficiency. The tribal population, characterized by distinct lifestyles and dietary habits, may experience unique influences on their growth and development. Aim: This study aimed to compare nerve conduction in newly diagnosed and untreated tribal women affected by hypothyroidism with euthyroid tribal women. Methods:A cross-sectional study was conducted in southern Odisha, India, spanning from April 2020 to January 2021. Forty-five newly diagnosed hypothyroid tribal women were enlisted from the outpatient department of general medicine as the case group. Additionally, 45 age-matched apparently healthy euthyroid tribal women were included as the control group. The subjects' height and weight were measured by an expert clinician. Nerve conduction (motor and sensory) study on both extremities (left and right side) were conducted for all participants in the human physiology laboratory. Results:The mean age of participants was 48.13±12.12 years in the case group and 47.18±12.2 years in the control group. In hypothyroid tribal women, a significant decrease in conduction velocity was observed in the majority of motor nerves (right median [p = .03], left median [p = .02], left ulnar [p = .04], right posterior tibial [p = .001], left posterior tibial [p = .0001]) and sensory nerves (right median [p =.005], right ulnar [p = .02], right sural [p = .001], and left sural [p = .02]). Conclusion:In newly diagnosed cases of hypothyroidism in tribal women, there is a risk of neuropathy that impacts both motor and sensory neurons. Therefore, it is crucial to initiate early diagnosis and immediate treatment to prevent additional neurological damage.

Hoffmann's syndrome in subclinical hypothyroidism

Hypothyroidism is an endocrine disorder which occurs due to a deficiency of thyroid hormones. Hoffmann's syndrome is a rare complication of hypothyroidism - presenting as hypothyroid myopathy. We describe the case of a 20-year-old lactating female, known to have hypothyroidism (diagnosed during her pregnancy and having discontinued treatment following delivery), presenting with complaints of pain, swelling of bilateral calf muscles with cramps in bilateral lower limbs. Symptoms of muscle pseudohypertrophy with muscle stiffness are relatively rare in subclinical hypothyroidism and it is important to identify and diagnose this rare condition, and initiate appropriate treatment.

Hypothyroidism in acute coronary syndrome - A prospective Indian study

BACKGROUND

Evidence suggests that hypothyroidism may be associated with an increased risk of acute coronary syndrome (ACS). The data regarding the influence of hypothyroidism on cardiovascular disease in the Asian population is conflicting. Therefore, we undertook this study to assess the overall prevalence of hypothyroidism in Acute Coronary Syndrome (ACS) patients and determine if there is a relationship between hypothyroidism, both sub-clinical and overt and other significant risk factors of ACS in an Indian population.

METHODS

We studied 487 hospitalized patients between March 2018 and February 2021 with a diagnosis of ACS to determine the prevalence of hypothyroidism, both clinical and sub-clinical and their relationship with other known coronary risk factors. Thyroid function Tests - free T3, free T4 and TSH were collected from all the patients within 24 h of their admission to the coronary care unit (CCU) of 2 major hospitals in New Delhi and Imphal (Manipur).

RESULTS

Subclinical hypothyroidism was prevalent in 44 (9 %), followed by overt hypothyroidism in 25 (5.2 %). Subclinical hypothyroidism was more common in females, whereas overt hypothyroidism was more common in males. ST Elevation Myocardial Infarction (STEMI) (52 %), followed by Non-ST-Elevation Myocardial Infarction (NSTEMI) (25 %), was the commonest diagnosis at presentation. Patients with overt hypothyroidism showed a higher proportion of increased triglyceride levels. Patients with hypothyroidism had no differences in the prevalence of concomitant diabetes hypertension and other coronary risk factors.

CONCLUSIONS

Patients with ACS without known thyroid disorders should be screened for hypothyroidism since it is found frequently. There might be a case to treat their thyroid dysfunction appropriately.

The relationship between subclinical hypothyroidism and invasive papillary thyroid cancer

Background

Subclinical hypothyroidism is the most common thyroid dysfunction. Approximately 10% of patients with thyroid cancer have subclinical hypothyroidism. There is a paucity of real-world studies examining the relationship between subclinical hypothyroidism and known correlates of invasiveness of papillary thyroid carcinoma (PTC).

Materials and methods

A retrospective cohort study of 13,717 patients with PTC was conducted. Odds ratios were calculated to assess the relationship between subclinical hypothyroidism and extrathyroidal extension (ETE) after adjusting for BMI and genders. The Cancer Genome Atlas (TCGA) data were utilized for the analysis of TSHR-associated pathways, while qRT-PCR was employed to validate the expression levels of pivotal genes in the relevant signaling pathways.

Results

In total, 13,717 PTC patients (10,769 women and 2,948 men; mean [SD] age, 42.90 [9.43] years) were included in the retrospective study. Subclinical hypothyroidism was an independent risk factor for ETE (OR adjusted, 1.168 [95% CI, 1.028-1.327]; P=0.017). In normal-weight patients, subclinical hypothyroidism was an independent risk factor for ETE (OR adjusted, 1.287 [95% CI, 1.089-1.520]; P=0.003). However, this risk was not observed in under-weight, overweight, and obese patients. Compared to females, subclinical hypothyroidism was a higher risk factor for ETE in male patients with normal body weight (OR male=2.363 vs. OR female=1.228). Subclinical hypothyroidism was found to be a significant risk factor for ETE in the subgroup of patients younger than 38 years old (OR1 adjusted, 1.382 [95% CI, 1.032-1.852], P=0.030). The findings from Gene Set Enrichment Analysis (GSEA) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis revealed the involvement of the autophagy signaling pathway in TSHR/ETE/EMT regulation. Moreover, the gene expression levels demonstrated a concentration-dependent relationship between TSH intervention levels and the expression of key genes in the autophagy pathway of thyroid cancer cells.

Conclusion

Subclinical hypothyroidism was an independent risk factor for ETE in patients with PTC. This association was particularly significant in normal-weight and younger patients. The risk of ETE associated with subclinical hypothyroidism was higher in males compared to females. Our study indicates a potential involvement of the autophagy pathway in regulating the ETE phenotype in thyroid cancer, specifically in the context of subclinical hypothyroidism.

Assessment of Serum Cortisol Levels in Hypothyroidism Patients: A Cross-Sectional Study

BACKGROUND

Hypothyroidism, characterized by insufficient thyroid hormone production, affects a significant global population, particularly women and the elderly. Recent research has emphasized the interaction between hypothyroidism and the hypothalamic-pituitary-adrenal (HPA) axis, highlighting cortisol's crucial role in the disease's physiological manifestations.

OBJECTIVE

This study aims to evaluate serum cortisol levels in hypothyroid patients, examining the intricate relationship between these two endocrine systems. By exploring the potential impact of altered cortisol levels on hypothyroidism's clinical presentation and progression, the study seeks to contribute valuable insights to enhance diagnostic approaches and develop more effective treatment strategies.

METHODS

A cross-sectional observational study was conducted at the Indira Gandhi Institute of Medical Sciences, assessing 65 hypothyroid cases and 65 age-matched euthyroid controls. Demographic data, medical history, and blood samples were collected, and serum cortisol, thyroid-stimulating hormone (TSH), triiodothyronine (T3), and thyroxine (T4) levels were measured. The study adhered to ethical considerations and received institutional approval.

RESULTS

The study included 65 hypothyroid cases (56 females, 9 males) and 65 euthyroid controls. Serum cortisol showed a significant correlation with TSH and T4 levels. Linear regression revealed a negative correlation between serum T4 and T3 levels and serum cortisol in hypothyroidism. A positive correlation was observed between TSH and cortisol. These findings align with previous studies, suggesting potential regulatory mechanisms and compensatory responses in hypothyroid patients.

DISCUSSION

The study's results emphasize the complex interaction between cortisol and thyroid function, suggesting a direct relationship between serum cortisol and TSH levels in hypothyroidism. Patients with severe hypothyroidism exhibited elevated cortisol concentrations, indicating a potential compensatory mechanism initiated by the HPA axis. Integrating serum cortisol assessment with conventional thyroid function tests could offer comprehensive insights into hypothyroidism severity and progression, providing a more holistic approach to patient care.

CONCLUSIONS

This study contributes to understanding the complex relationship between serum cortisol levels and hypothyroidism, emphasizing the need for further research to uncover underlying mechanisms and therapeutic implications. A comprehensive understanding holds the potential for more tailored and effective treatment strategies for individuals with hypothyroidism.

Pharmacist-Mediated Thyroid-Stimulating Hormone (TSH) Test Guideline Monitoring Program- Outcomes of a Retrospective Study In Patients On Levothyroxine

Thirty to sixty percent of individuals taking levothyroxine were either under or overtreated, which leads to organ damage and excess mortality. This study aims to assess the gaps in the "thyroid-stimulating hormone (TSH) test guideline compliance rate" and validate the scope of ambulatory care pharmacist-mediated practice in patients on levothyroxine. At the study site, pharmacists offered patient-centered telephonic counseling to patients on levothyroxine who had been non-compliant with TSH tests for more than a year. A two-month quantitative retrospective analysis of this practice was conducted to assess its impact on TSH lab test adherence and dose modification outcomes. 415 patients met the study's inclusion criteria who received pharmacist counseling with documented intervention. Pharmacists bridged the significant gap in practice by creating new TSH lab requests with counseling in 81.2% (n = 337) of the study population who did not have TSH lab requests prior to the program. The non-compliance rate population dropped from 79.27% (n = 329) to 17.59% (n = 73) in the study population who had been non-compliant with the TSH test for 13 and 24 months. 74.5% (n = 309) were found to have performed their TSH test after the pharmacist's intervention. Among 100, 66% (n = 66) patients with abnormal TSH values consulted their physician for advice, of which 60.6% (n=40) had their levothyroxine dose adjusted (χ2=82.702, P < 0.01. The study suggests that pharmacists can significantly mediate between patients and physicians to enhance TSH test compliance and essential dose adjustment in patients prescribed levothyroxine.

Thyroxine biosensors: a review on progress and challenges

Hypothyroidism is a global concern that needs to be monitored, controlled and treated. Thyroxine is the most common biomarker for the diagnosis of hypothyroidism and a therapeutic hormonal replacement for hypothyroid patients. People suffering from hypothyroidism need to monitor their levels of thyroxine to avoid health complications. Diagnostic labs are not always easily accessible and, hence, point-of-care biosensors can become a useful alternative. Several studies have shown high sensitivity, selectivity and stability but there is no commercial point-of-care biosensing device available. This paper presents the critical aspects, including the need for thyroxine biosensors, the physicochemical properties of the thyroxine molecule, nanomaterials and bioreceptors used for sensing. The challenges and prospects of thyroxine biosensors are also discussed.

Adherence to levothyroxine treatment among patients with hypothyroidism in Oman: a national cross-sectional study

OBJECTIVE

Hormone replacement therapy with levothyroxine is considered the treatment of choice for hypothyroidism; however, non-adherence is a major contributor to poor treatment outcomes. This study aimed to evaluate levels of drug adherence (DA) to levothyroxine therapy among Omani adults with hypothyroidism and to explore related sociodemographic and clinical factors.

METHODS

A national, multi-center, cross-sectional survey was carried out from August to December 2021 at 18 primary healthcare centers across all governorates of Oman. A total of 415 Omani adults were recruited. Data were collected using a pre-tested, Arabic-language questionnaire completed by trained researchers during face-to-face interviews with the participants. Level of DA was determined using the 8-item Morisky Medication Adherence Scale (MMAS-8).

RESULTS

A total of 400 Omani adults participated in the study (response rate: 96.4%). The mean age was 41.9 ± 12.4 years old (range: 18-78 years) and 90.3% were female. According to their MMAS-8 scores, 157 (39.2%), 139 (34.8%), and 104 (26.0%) participants demonstrated low, medium, and high DA, respectively. No significant correlations were observed between level of DA and any sociodemographic or clinical characteristics, including age, gender, education, duration of treatment, and family history of thyroid disease (p > 0.050).

CONCLUSIONS

Only a quarter of Omani patients with hypothyroidism reported high levels of adherence to levothyroxine treatment, likely as a result of lack of awareness of the disease and the importance of maintaining an euthyroid state. Further studies using more objective measures of DA are recommended to determine correlates of non-compliance to levothyroxine therapy among Omani patients.

Health-related quality of life and its association with the symptom score and the thyroid function status of patients with primary hypothyroidism on replacement therapy

BACKGROUND

A number of patients with primary hypothyroidism have reduced health-related quality of life (HR-QoL), even with optimum thyroid hormone replacement therapy. This study aimed to assess the HR-QoL of patients with hypothyroidism under replacement therapy and identify its relationship with the symptom score and thyroid function status.

MATERIALS AND METHODS

Using a cross-sectional study design, 175 hypothyroid patients under replacement therapy who visited the Endocrinology Outpatient Department of a tertiary care center were selected by convenient sampling technique. Data was collected using a structured data collection tool comprising, HR-QoL Short Form-36 questionnaire, and Zulewski's clinical score. Inferential statistical analyses were performed using Mann-Whitney U, Kruskal-Wallis, and Karl-Pearson Correlation tests.

RESULTS

The overall mean quality of life score was 44.22 ± 12.14, with a substantial decline in role functioning because of physical health. A significant negative correlation (P < 0.05) was found between HR-QoL and hypothyroidism symptom score. A significant association was observed between participants' HR-QoL and their dosage of thyroxine supplement (P < 0.05,) but no association was found with thyroid function status.

CONCLUSION

There was a substantial reduction in the quality of life of the patients despite being on thyroid replacement therapy and achieving euthyroid status. This underlines the importance of symptom reduction and hormone optimization to enhance the quality of life.

Hashimoto's Thyroiditis among Patients with Thyroid Disorders Visiting a Tertiary Care Centre

Introduction

Hashimoto's thyroiditis is a chronic autoimmune lymphocytic thyroiditis characterised by thyroid autoantibodies. Early detection and treatment of this condition help in reducing the morbidity and mortality associated with it. The aim of the study was to find out the prevalence of Hashimoto's thyroiditis among patients with thyroid disorders visiting a tertiary care centre.

Methods

A descriptive cross-sectional study was conducted among patients visiting the outpatient department of a tertiary care centre. Data from 14 April 2017 to 13 April 2019 was collected between 30 June 2022 to 15 September 2022 from medical records. Ethical approval was obtained from the Nepal Health Research Council. Hashimoto's thyroiditis was diagnosed based on clinical presentation and positive antibodies to thyroid antigens. Convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval.

Results

Among 813 patients with thyroid disorders, 393 (48.33%) (44.89-51.77, 95% Confidence Interval) had Hashimoto's thyroiditis. The manifestation of the spectrum of Hashimoto's thyroiditis were euthyroid in 215 (54.70%), subclinical hypothyroidism in 102 (25.95%), subclinical hyperthyroidism in 23 (5.85%), overt hyperthyroidism in 9 (2.30%) and overt hypothyroidism in 4 (1.02%).

Conclusions

The prevalence of Hashimoto's thyroiditis among patients with thyroid disorders was higher than in other studies done in similar settings.

Prevalence and risk factors of hypertension with thyroid dysfunction among indian adults: Synthesis from national family health survey (2015-16)

Background

Thyroid dysfunction (TD) is considered a common cause of secondary hypertension (HT). Therefore, correcting TD may help in quicker and sustained achievement of desired blood pressure goals. However, there is a paucity of literature from India which estimates the relationship of HT with TD.

Objectives

The objective of the study was to estimate the prevalence of TD with HT and to identify associated factors among Indian population.

Materials and Methods

The survey data of the National Family Health Survey 4 (NFHS-4), conducted in India during 2015-2016, were analyzed using R statistical software for estimating the relationship between a history of HT and TD among women (N = 687246) aged 15-49 years and men (N = 108492) aged 15-54 years. Descriptive statistical tests and logistic regression were applied.

Results

Among the persons suffering from the TD, the prevalence of HT was 32.8%, which was significantly higher than the prevalence of HT (21.9%) in euthyroid individuals. Further, the prevalence of TD was higher among hypertensive adults (2.5%) compared to nonhypertensive (1.5%).

Conclusions

The study reported a higher prevalence of TD among the hypertensive persons and higher prevalence of HT among cases of TD. Therefore, screening for thyroid disorders should be routinely considered for better management of HT.

Examining Body Fat Percentage, Galvanic Skin Response, and Muscle Grip Strength in Female Hypothyroid Patients

Background The thyroid gland is an indispensable organ exerting control over the activity of multiple organ systems including the autonomic nervous system. This study attempted to monitor the variations in autonomic function parameters such as galvanic skin response (GSR) and muscle grip strength (HGS) in conjunction with changes in body fat percentage (BFP). Methodology This case-control study was conducted among 40 female hypothyroid patients as cases and 40 age-matched female healthy volunteers as controls. Anthropometric data were collected using standard techniques. GSR and HGS were measured using Equivital Sensory Electronic Module and Grip Force Transducer, respectively. Data extraction and analysis were done using the LabChart software. Results The mean age of the 40 female hypothyroid patients was 30.14 ± 5.91 years, whereas the mean age of the female controls was 29.37 ± 6.59 years. The waist circumference of cases was 85.81 ± 10.39 cm while that of controls was 80.90 ± 11.18 cm. The BFP of cases was 35.38% ± 6.74% while that of controls was 31.72% ± 5.63%. The GSR amplitude showed a significant difference between hypothyroid and healthy volunteers with values of 1.34 ± 1.14 μS and 2.40 ± 1.86 μS, respectively. The HGS indices showed no significant difference between the two groups. A statistically negative correlation was noted between BFP and GSR amplitude (-0.32), whereas a positive correlation was noted between BFP and mean handgrip strength (0.31) in hypothyroid patients. Conclusions The changes in BFP and autonomic function through GSR and HGS were evaluated in female hypothyroid patients with respect to healthy females. The interrelationship between anthropometry and autonomic function was also explored in this study. The findings of this study can augment prognosis in patients and ensure timely corrective treatment for improving quality of life.

Sex-Based Differences in Clinical Profile and Complications among Individuals with Type 2 Diabetes Seen at a Private Tertiary Diabetes Care Centre in India

This study aimed to compare the clinical and biochemical profiles as well as the complications in males and females with type 2 diabetes (T2DM) presenting to a private tertiary diabetes care centre in India. This is a retrospective study, conducted between 1 January 2017 and 31 December 2019, and included 72,980 individuals with T2DM, aged ≥ 18 years (age and sex-matched-males-36,490; females-36,490). Anthropometric measurements, blood pressure, fasting plasma glucose (FPG), post-prandial plasma glucose (PPPG), glycated haemoglobin (HbA1c), lipids, urea, and creatinine were measured. Retinopathy was screened using retinal photography, neuropathy using biothesiometry, nephropathy measuring urinary albumin excretion, peripheral vascular disease (PVD) using Doppler, and coronary artery disease (CAD) based on the history of myocardial infarction and/or drug treatment for CAD and/or electrocardiographic changes. Obesity (73.6% vs. 59.0%) rates were significantly higher in females compared to males. FPG, PPPG, and HbA1c were higher among younger age groups among both sexes, with males having higher values compared to females. However, after the age of 44 years, control of diabetes was worse among females. In addition, only 18.8% of the females achieved glycemic control (HbA1c < 7%) compared to 19.9% in males (p < 0.001). Males had higher prevalence of neuropathy (42.9% vs. 36.9%), retinopathy (36.0% vs. 26.3%), and nephropathy (25.0% vs. 23.3%) compared to females. Males had 1.8- and 1.6-times higher risk of developing CAD and retinopathy compared to females. Hypothyroidism (12.5% vs. 3.5%) and cancers (1.3% vs. 0.6%) were significantly higher in females compared to males. In this large sample of T2DM seen at a chain of private tertiary diabetes centres, females had higher prevalence of metabolic risk factors and poorer diabetes control compared to males, emphasizing the need for better control of diabetes in females. However, males had higher prevalence of neuropathy, retinopathy, nephropathy, and CAD compared to females.

Effect of morning versus night-time administration of proton pump inhibitor (pantoprazole) on thyroid function test in levothyroxine-treated primary hypothyroidism: a prospective cross-over study

BACKGROUND

One of the common causes of suboptimal control of thyroid stimulating hormone (TSH) in levothyroxine-treated hypothyroidism is coadministration of proton pump inhibitors (PPIs). Morning administration of pantoprazole has been shown to suppress intragastric pH to a greater extent. We therefore aimed to determine the effect of pantoprazole at different time points of the day on thyroid function test (TFT) in levothyroxine-treated overt primary hypothyroidism.

METHODS

In this single centre, hospital based, prospective, two arm cross-over study (AB, BA), participants were randomized into 2 groups based on morning (6:00 am - 7:00 am simultaneously with the scheduled levothyroxine tablet) (group M) and evening (30 min before dinner) intake of 40 mg pantoprazole tablet (group N). After the initial 6 weeks (period 1), a washout period of 1 week for pantoprazole was given, and then both the groups crossed over for another 6 weeks (period 2). Patients were instructed to continue the same brand of levothyroxine tablet at empty stomach 1-hour before breakfast. Serum TSH was measured at baseline, week 6, and week 13.

RESULTS

Data from 30 patients, who completed the study with 100% compliance, were analysed. Mean TSH values of the study participants were significantly higher both at week 6 and week 13 compared to the baseline. Mean baseline serum TSH concentrations for groups M and N were 2.70 (± 1.36), and 2.20 (± 1.06) µlU/mL, respectively. Mean serum TSH concentrations at the end periods 1 and 2 for group M were 3.78 (± 4.29), and 3.76 (± 2.77) while the levels in group N were 3.30 (± 1.90), and 4.53 (± 4.590) µlU/mL, respectively. There was a significant rise in serum TSH concentration across periods 1 and 2 in both the groups (F_{2, 58} = 3.87, p = 0.03). Within group changes in TSH across periods 1 and 2 were not statistically significant. Similarly difference in TSH between the groups, either at 6 weeks or at 13 weeks, were also not statistically significant.

CONCLUSIONS

Concomitant use of pantoprazole, even for 6 weeks, leads to significant elevation in serum TSH in levothyroxine-treated patients who are biochemically euthyroid, irrespective of timing of pantoprazole intake. Early morning and night-time administration of pantoprazole have similar effect on TFT in these patients.

A Prospective Observational Study to Evaluate Cardiovascular Changes in Patients of Hypothyroidism

Introduction Hypothyroidism is a common endocrine disorder in India and is easy to diagnose based on clinical manifestations and signs. Thyroid hormone affects the cardiovascular system. Fatiguability, dyspnea, weight gain, lower limb swelling, and bradycardia are some clinical manifestations. ECG changes in hypothyroidism include sinus bradycardia, prolonged QTc interval, changes in the morphology of the T-wave, QRS duration, and low voltage. Echocardiography changes include diastolic dysfunction, asymmetrical septal hypertrophy, and pericardial effusion. This study aimed to examine the cardiovascular changes in patients with hypothyroidism. Methodology Patients with hypothyroidism and cardiovascular changes were assessed using an electrocardiogram and echocardiography. Results A total of 68 hypothyroid patients were enrolled in the study. The mean age of patients was 41.93 ± 15.36 years, and the mean BMI was 24.64 ± 4.30 kg/m². Of 68 hypothyroid patients, 57 (83.8%) were females, and 11 (16.2%) were males. The mean thyroid-stimulating hormone (TSH) level in the study population was 11.48 ± 22.02 (mIU/mL). The most common symptoms reported among the study participants were tiredness or weakness (67.6%), followed by dyspnea (42.6%). The mean pulse rate, systolic blood pressure, and diastolic blood pressure were 81.50 ± 16.16, 112.76 ± 7.05, and 70.68 ± 7.46, respectively. Pallor was the most common sign (22.1%) among all the people who participated in the study. The most common findings on the ECG were low voltage complexes (25%) followed by inversion of the T wave (23.5%). Other ECG findings were bradycardia (10.3%), right bundle branch block (7.4%), and QRS prolongation (2.9%). Echocardiography revealed 21 (30.8%) patients with grade 1 left ventricular diastolic dysfunction and pericardial effusion in two patients (2.94%). There was a significantly greater increase in the level of TSH in study participants. Conclusion Patients with abnormal ECG and echocardiography without other cardiovascular changes should be evaluated for hypothyroidism to improve the quality of care.

Diabetes among Patients with Overt Primary Hypothyroidism Visiting the Outpatient Department of General Medicine of a Tertiary Care Centre: A Descriptive Cross-sectional Study

Introduction

Thyroid diseases are one of the commonest endocrine disorders and hypothyroidism is the commonest among them. There are many publications about hypothyroidism prevalence in diabetes, however, reports of diabetes in hypothyroidism are scarce. This study aimed to find out the prevalence of diabetes among patients with overt primary hypothyroidism visiting the Outpatient Department of General Medicine of a tertiary care centre.

Methods

A descriptive cross-sectional study was conducted among adults with overt primary hypothyroidism who attended the Department of General Medicine of a tertiary care centre. Data from 1 November 2020 to 30 September 2021 were collected between 1 December 2021 and 30 December 2021 from the hospital records. Ethical approval was obtained from Institutional Review Committee (Reference number: MDC/DOME/258). Convenience sampling method was used. Out of all patients with different thyroid disorders, consecutive patients with overt primary hypothyroidism were included. The patients with incomplete information were excluded. Point estimate and 95% Confidence Interval were calculated.

Results

Among total 520 patients with overt primary hypothyroidism, the prevalence of diabetes was 203 (39.04%) (34.83-43.25, 95% Confidence Interval), with 144 (70.94%) in female and 59 (29.06%) in male. Among 203 hypothyroid patients with diabetes, the proportion of female was more than that of male.

Conclusions

The prevalence of diabetes among patients with overt primary hypothyroidism was higher than the other studies done in similar settings.

Phytochemical profiling of polyphenols and thyroid stimulatory activity of Ficus religiosa leaf extract in 6-propyl-thiouracil-induced hypothyroid rats

ETHNOPHARMACOLOGICAL RELEVANCE

The plant, Ficus religiosa (L.) from the family Moraceae, has been extensively used in Ayurveda and Unani. Traditionally this plant is known for the treatment of constipation, liver diseases and neurological disorders that are related to hypothyroidism.

AIM OF THE STUDY

This study was primarily designed to evaluate the effect of Ficus religiosa leaf (FL) extract in ameliorating hypothyroidism in rats and to identify the major bioactive compounds in the test extract that might be responsible for the thyroid-altering activity. In addition, the probable mechanism underlying the thyroid regulation of the main FL constituents were analyzed by molecular docking.

MATERIALS AND METHODS

Adult female Wistar rats were used. LC-ESI-MS/MS was performed to identify the compounds present in the extract. HPLC analysis of FL extract was also performed. A pilot study was made using 3 doses of FL extract. Out of 50, 100, and 200 mg/kg, 100 mg/kg appeared to be the most effective one as it could increase thyroid hormones and decreased TSH levels. In the final experiment, propyl-thiouracil (PTU)-induced hypothyroid rats were orally treated with FL extract (100 mg/kg) or L-thyroxine (100 μg/kg, i.p.) daily for 28 consecutive days. On 29th day, all rats were sacrificed and the serum levels of triiodothyronine (T₃), thyroxine (T₄), thyrotropin (TSH), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and hepatic 5' deiodinase-1(5'D1) were estimated by ELISA. Liver marker enzymes (alanine aminotransferase, ALT and aspartate aminotransferase, AST); total cholesterol (TC) and triglycerides (TG); hepatic lipid peroxidation (LPO) and the activities of antioxidants such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and glutathione (GSH) content were estimated in liver tissues.

RESULTS

LC-MS-MS analyses of the leaf extract identified 11 compounds including the three major compounds, betulinic acid (BA), chlorogenic acid (CGA), and quinic acid (QA). While the PTU treatment decreased the levels of thyroid hormones and 5'D1 activity, it increased the TSH, ALT, AST, TNF-α, IL-6, TC, and TG levels. Furthermore, hepatic LPO significantly increased with a decrease in reduced GSH, SOD, CAT, and GPx. However, FL treatment in PTU-induced animals nearly reversed these adverse effects and improved liver function by decreasing ALT, AST, hepatic LPO and increasing the levels of antioxidants. FL not only improved the liver histology, but also suppressed the inflammatory cytokines, TNF-α and IL-6 in PTU-induced animals. A molecular docking study towards the understanding of the thyroid stimulatory mechanism of action revealed that BA, CGA, and QA might have augmented thyroid hormones by interacting with the thyroid hormone receptor (TRβ1) and TSH receptor (TSHR).

CONCLUSION

For the first time, we report the pro-thyroidal potential of Ficus religiosa leaf extract. We postulate that its main bioactive compounds, BA, CGA, and QA involved in this action may serve as novel thyroid agonists in ameliorating hypothyroidism.

ILSHIP: An interpretable and predictive model for hypothyroidism

Hypothyroidism is one of the common endocrine diseases, and its incidence is increasing year by year. Due to the insidious nature of this disease, it often leads to delayed treatment and even misdiagnosis. This paper proposes ILSHIP, an interpretable predictive model for hypothyroidism, to reduce its diagnostic complexity as well as improve the predictive performance and interpretability of existing models. First, the ILSHIP prediction model was built based on label encoding, missing value processing, feature selection, and data enhancement of the dataset. Second, the comprehensive performance of ILSHIP was compared with twelve existing related study models and eleven mainstream models, such as XGBoost and MLP. The experimental results showed that, based on the optimal hyperparameters the ILSHIP model can achieve 99.392%, 99.437%, 99.348%, 99.381%, and 99.960% in accuracy, recall, specificity, F1, and AUC, respectively. The accuracy of the ILSHIP model was about 0.7%-15.4% higher than the existing models. By introducing the SHAP framework into the ILSHIP model, important features affecting hypothyroidism such as thyroid stimulating hormone (TSH) and free thyroxine index (FTI) were also identified, and the influencing factors for different individuals were finally analyzed to provide a basis for medical personnel to monitor the condition.

Cognitive decline in mid-life: Changes in memory and cognition related to hypothyroidism

This study assessed specific cognitive impairments within a primarily female, hypothyroid population, while controlling for factors that commonly contribute to cognitive decline. Participants (N = 739) included 461 individuals with hypothyroidism. This study involved an online survey assessing several aspects of memory and cognition. Those with hypothyroidism generally scored worse on self-assessments of memory, higher perceived stress, high rates of depression and anxiety, greater fatigue, poorer concentration, and less motivation. A Receiver Operating Characteristic curve indicated that the cognitive questionnaires are successful at classifying hypothyroidism and a mediation analysis showed fatigue is a mediating symptom of these cognitive outcomes.

Prevalence and risk factors of hypothyroidism after universal salt iodisation: a large cross-sectional study from 31 provinces of China

OBJECTIVES

To investigate the prevalence and risk factors of hypothyroidism after universal salt iodisation for 20 years in mainland China.

DESIGN

Nationwide, cross-sectional survey.

SETTING AND PARTICIPANTS

The Thyroid Disorders, Iodine Status and Diabetes epidemiological study included adults from 31 provinces of China. Data included demographic, physical characteristics, urine, serum thyroid-stimulating hormone (TSH), thyroid-peroxidase antibody (TPOAb), thyroglobulin antibody (TgAb) and thyroid ultrasonography. Subclinical hypothyroidism (SCH) was classified into severe SCH (TSH >10 mU/L) and mild SCH (TSH 4.2-9.9 mU/L). A total of 78 470 (38 182 men and 40 288 women) participants were included in the final analysis.

RESULTS

The prevalence of hypothyroidism was 13.95%. The prevalence rates of overt hypothyroidism (OH) and SCH were 1.02% and 13.93%, which mild SCH was significantly higher than severe SCH (12.18% vs 0.75%). Prevalence was higher in women than in men, and this gender difference was noted among all age groups. The prevalence of mild SCH, severe SCH and OH increases by 1.16%, 1.40% and 1.29% for every 10 years older. TPOAb or/and TgAb positive were significantly associated with OH and severe SCH (OR 15.9, p<0.001). However, SCH was positively correlated with increased urine iodine concentration, but this correlation was only in antibody-negative female patients. In non-autoimmune and male populations, there was a U-shaped relationship between severe SCH and OH and urine iodine concentration.

CONCLUSIONS

Mild SCH is the most common form of hypothyroidism, which is related to iodine intake. Severe SCH is more similar to OH which autoimmune is the main cause. The various effects of iodine on hypothyroidism depend on thyroid autoimmune and gender.

The management and metabolic characterization: hyperthyroidism and hypothyroidism

Hyperthyroidism and hypothyroidism are common diseases resulting from thyroid dysfunction, and are simple to diagnose and treat. The traditional treatment for hypothyroidism is thyroid hormone replacement therapy. The traditional treatments for hyperthyroidism include antithyroid drug, iodine radiotherapy, and surgery. Thyroid disease can be fatal in severe cases if untreated. Current statistical reference ranges used for diagnosis based on relevant biochemical parameters have been debated, and insufficient treatment can result in long-term thyroid hormone deficiency, which is associated with increased risk of cardiovascular disease and persistent symptoms. In contrast, overtreatment can result in heart disease and osteoporosis, particularly in older people and pregnant women. Therefore, under- or over-treatment should be avoided and treatment regimens should be monitored closely. A significant proportion of patients who achieve biochemical treatment goals still complain of significant symptoms. Systematic literature review was performed through the Embase (Elsevier), PubMed and Web of Science databases, and studies summarized evidence regarding treatment and management of hypothyroidism and hyperthyroidism, and reviewed clinical practice guidelines. We also reviewed the latest research on the metabolic mechanisms of hyperthyroidism and hypothyroidism, which contributed to understanding of thyroid diseases in the clinic. A reliable algorithm is needed to management, assessment, and treatment patients with hyperthyroidism and hypothyroidism, which can not only improve management efficiency, but also providing a broad application. In addition, the thyroid disorder showed a lipid metabolism tissue specificity in the Ventromedial Hypothalamus, and effect oxidative stress and energy metabolism of whole body. This review summarizes an algorithm for thyroid disease and the latest pathogenesis that would be useful to generalist and subspecialty physicians and others providing care for patients with this condition.

Dyslipidaemia and inflammatory markers as the risk predictors for cardiovascular disease in newly diagnosed premenopausal hypothyroid women

Background

Hypothyroidism can predispose systolic and diastolic cardiac dysfunction, increased peripheral vascular resistance, endothelial dysfunction, altered coagulopathy, and dyslipidemia resulting in atherosclerosis. Thyroid hormones can influence homocysteine metabolism by regulating the methylenetetrahydrofolate reductase (M THR). So, this study aimed to compare the markers homocysteine, high sensitive C-reactive protein (hs-CRP), and Atherogenic Indices (AI) between newly diagnosed hypothyroid and euthyroid premenopausal women.

Methods

80 Female patients between 20 and 45 years were enrolled in this study and were equally divided into cases and controls group. Laboratory tests included: i) Serum T3, T4, TSH was measured using electrochemiluminescence, ii) lipid profile, homocysteine, and hs-CRP were measured for all the participants. Atherogenic indices: Castelli risk indices I&II, Atherogenic coefficient (AEC), and Atherogenic Index of Plasma (AIP) were calculated using formulas. A comparison between the study groups was made by using the Independent t-test and Mann-Whitney U test. p-value < 0.05 was considered significant.

Results

The hypothyroid group had significantly higher levels of homocysteine (p= 0.014), and hs-CRP (hs-CRP> 3.0 mg/L, 70% of participants have intermediate to high risk for a cardiovascular event) and elevated BMI compared to participants in the euthyroid group. Atherogenic indices (p< 0.001) was significantly increased in the hypothyroid participants' group. TC, TG , and LDL were significantly elevated in the hypothyroid group but did not show any association with systolic and diastolic blood pressure.

Conclusions

Premenopausal women with hypothyroidism have a greater predisposition for cardiovascular disease compared to euthyroid.

Clinico-epidemiological profile of women with high-risk pregnancy utilizing antenatal services in a rural primary health center in India

Objective: Early detection and effective management of high-risk pregnancies can substantially contribute to the reduction of adverse maternal and fetal outcomes. This study aimed to determine the prevalence and clinical profile of women with high-risk pregnancies in rural areas who utilize antenatal services in a primary health center (PHC). Materials and Methods: A retrospective analysis was carried out over a six-month period by reviewing the mother and child protection cards maintained at the PHC's Maternal and Child Health Center. During the study period, 950 pregnant women were registered, of whom 793 were included in the study based on the completeness of the records. Data analysis was performed using the licensed Statistical Package for the Social Sciences (SPSS) software version 21.0. Results: The prevalence of high-risk pregnancy among the antenatal women was 272 (34.3%) with 95% CI [31.1-37.7]. Of the 272 women, 240 (88.2%) had a single high-risk factor, while 32 (11.8%) had more than one high-risk factor. The major factor contributing to high-risk pregnancy was hypothyroidism (43.7% with 95% CI [37.9-49.6]), followed by a previous lower segment Caesarean section (LSCS) (19.1%). Conclusion: The study found that the prevalence of high-risk pregnancies was 34.3% in this rural setting. The majority of high-risk pregnancies were due to hypothyroidism, followed by more than one previous LSCS or abortion. Further research is required to track high-risk pregnancy outcomes and investigate the newborn thyroid profile of women with hypothyroidism.

Bangladesh Endocrine Society Guidelines for the Diagnosis and Management of Thyroid Disease During Pregnancy and the Postpartum

Background:

In Bangladesh, patients with thyroid disorders are managed in accordance with the recognized guidelines and based on expert experience, as comprehensive national guidelines are currently lacking. The Bangladesh Endocrine Society (BES), as a professional body, has been working to develop guidelines for the last couple of years. Most recently, BES formulated practical recommendations for the management of thyroid disorders during pregnancy, which will be termed the “Guideline on Thyroid Disorders in Pregnancy in Bangladesh 2022,”

Methods:

The BES formed a task force comprising experts in this field to formulate the practical recommendations for the management of thyroid disorders during pregnancy under several sections. The members of this task force comprehensively reviewed the available evidence for the specific conditions. Three well-known databases (Google Scholar, PubMed, and Scopus) were searched to determine the evidence. The task force members were well trained on reviewing the documents and methods of evidence synthesis. Each section of the recommendation was drafted by one member and subsequently reviewed. There was no barrier to the date or type of article published in the aforementioned databases except for articles published other than English. Due to the scarcity of intervention studies, ideas and findings of observational studies, case studies and expert recommendations were considered during the formulation of the guidelines. All members and affiliated persons declared no competing interest, and it was managed and communicated by the President of the BES.

Results:

The current guidelines for the management of thyroid disease in pregnancy include recommendations about the screening of thyroid function in pregnancy, planning pregnancy in women with thyroid disorders, interpretation of thyroid function tests, management of hypothyroidism and hyperthyroidism in pregnancy, management of thyroid nodules and thyroid emergencies throughout pregnancy, postpartum care, and directions of future research.

Conclusions:

Our utmost efforts were centered on developing evidence-based recommendations to inform all the levels of clinicians of Bangladesh for the easy understanding and decision-making processes in the management of thyroid disorders in pregnancy and afterward. While we care most to prepare the guideline, all recommendations are the opinion of society and admit the scope of making individualized decisions for the optimal care of patients.

Practical and Pragmatic Usage of T3 in Hypothyroidism

Hypothyroidism is one of the common endocrine disorders encountered in clinical practice. Though thyroxine (T4) remains the treatment of choice in most clinical situations, with the recent introduction of oral triiodothyronine (T3) in South Asian countries, it is important to know about its utility in clinical practice. In this brief communication, we delineate potential clinical indications for T3 therapy, while highlighting possible concerns and caveats.

Clinical characteristics and surgical management of endometriosis-associated infertility: A multicenter prospective cohort study

OBJECTIVE

To study clinical, surgical characteristics and the relationship between endometriosis lesion types and conception rate after surgery in infertile women with endometriosis.

METHODS

A prospective, multicenter cohort of 204 women (age 20-35 years) with endometriosis was followed up post-surgery between November 2017 and February 2020 at three tertiary-care hospitals.

RESULTS

Based on the severity of endometriosis lesion type, deep infiltrating endometriosis (DIE) (81/204, 39.7%) was the most common lesion; followed by ovarian endometriosis (OMA) (64/204, 31.4%), and superficial peritoneal endometriosis (SUP) (59/204, 28.9%). Endometriosis patients had a single lesion type (94/204, 46.1%), two lesion types (77/204, 37.7%), or three lesion types (33/204, 16.2%) with significant differences between regions (P < 0.001). Around 40% (37/95) of obese women had SUP (P = 0.003) whereas 78% (14/18) of underweight women had DIE (P < 0.001). Significant differences in mean Endometriosis Fertility Index scores between endometriosis lesion types and patients with one, two, and three types of lesions were observed (P < 0.001). The majority (22/32, 68.8%) of the women conceived naturally after the surgery. Half (16/32; 50%) of the women with a single lesion type conceived after the surgery; of which most (13/16, 81.2%) had SUP, followed by OMA (2/16, 12.5%), and DIE (1/16, 6.3%).

CONCLUSION

Women with SUP and only one type of endometriotic lesion were more likely to conceive post-surgery.
