Primary Adrenal Insufficiency due to Cryptococcus With Persistent Adrenal Enlargement and Insufficiency

Background/Objective

Infiltrative fungal infections are an unusual cause of primary adrenal insufficiency (AI). Our objective is to present a long-term follow-up of a patient with AI due to cryptococcal adrenalitis.

Case Report

A 47-year-old woman presented in January 2004, with 50-lb weight loss, nausea, emesis, and headache with diplopia. During the 6 months prior to her presentation the patient had multiple admissions for evaluation of recurrent nausea and emesis. Prior to the most recent of these admissions, the patient developed a headache; evaluation of her cerebrospinal fluid revealed the presence of Cryptococcus, and she was treated with a 2-week course of amphotericin B. Physical examination demonstrated a temperature of 101.1 °F, heart rate of 110 bpm, and blood pressure of 94/65 mm Hg. She appeared ill and was underweight with dry mucous membranes and photophobia. Laboratory tests revealed random cortisol of 0.5 μg per dL. CT imaging showed bilateral adrenal gland enlargement and fine needle aspiration of the adrenal gland revealed encapsulated budding yeast. Stress dose intravenous glucocorticoids were administered and switched to oral hydrocortisone and fludrocortisone because the patient clinically improved with a second course of amphotericin B. Further evaluation in 2017 revealed persistently enlarged adrenal glands, positive cryptococcus antigen, and low IgG levels.

Discussion

Our literature review noted few publications of AI caused by disseminated cryptococcus with no long-term follow-up of these cases beyond a 1- to 4-year time frame.

Conclusion

Patients with AI due to disseminated fungal infection need long-term follow-up to assess for resolution of adrenal enlargement and evaluation of immunocompromised status.

Cognitive dysfunction in patients with primary adrenal insufficiency: A systematic review

Addison's disease (AD) entails a chronic insufficient production of gluco- and mineralocorticoids. Fatigue and decreased quality of life are frequently reported symptoms, but little is known about its effects on cognition. This study aims to explore the existence of cognitive impairment in patients with AD and the influence of treatment regimens. We conducted a systematic review. Inclusion criteria were met by 10 articles, most of them ranked as intermediate quality. Three studies analyzed the relationship between AD and cognitive impairment; one explored the effect of delaying treatment showing no effect on cognitive performance, and another one studied the effect of fludrocortisone treatment. Episodic memory was the most frequent cognitive domain impaired across studies, in comparison to healthy controls. Two papers investigated the relationship between impaired sleep quality and poor cognitive performance. Two studies related cognitive impairments with hypocortisolism-derived brain neuroglycopenia. Two studies investigated the effect of DHEA substitution. In conclusion, patients exhibit a moderately reduced performance in verbal learning. The pathophysiology of this impairment is likely multifactorial. Future studies should include larger sample sizes, the use of comprehensive and multi-domain neuropsychological and behavioral protocols, and neuroimaging.

Early Detection of Adrenal Insufficiency: The Impact of Newborn Screening for Adrenoleukodystrophy

CONTEXT

Males with adrenoleukodystrophy (ALD) have an 80% lifetime risk of developing adrenal insufficiency (AI), which can be life-threatening when undetected. Newborn screening (NBS) for ALD has been implemented in 29 states, yet the impact of NBS upon clinical management has not been reported.

OBJECTIVE

To investigate whether the implementation of NBS has altered the time to diagnosis of AI in children with ALD.

DESIGN

We conducted a retrospective medical chart review of pediatric patients with ALD.

SETTING

All patients were seen in a leukodystrophy clinic in an academic medical center.

PATIENTS

We included all pediatric patients with ALD who were seen between May 2006 and January 2022. We identified 116 patients (94% boys).

MAIN OUTCOME MEASURES

We extracted information about ALD diagnosis in all patients and AI surveillance, diagnosis, and treatment in boys with ALD.

RESULTS

Thirty-one (27%) patients were diagnosed with ALD by NBS, and 85 (73%) were diagnosed outside the newborn period. The prevalence of AI among boys in our patient population was 74%. AI diagnosis was made significantly earlier in boys diagnosed with ALD by NBS than in boys diagnosed outside the newborn period (median [IQR] age of diagnosis = 6.7 [3.9, 12.12] months vs 6.05 [3.74, 8.35] years) (P < .001). When maintenance dose of glucocorticoids were initiated, there were significant differences in ACTH and peak cortisol levels in patients diagnosed by NBS and outside the newborn period.

CONCLUSIONS

Our results suggest that implementing NBS for ALD leads to significantly earlier detection of AI and earlier initiation of glucocorticoid supplementation in boys affected by ALD.

Glucocorticoid Replacement for Adrenal Insufficiency and the Development of Non-Alcoholic Fatty Liver Disease

Glucocorticoid excess is a known risk factor for non-alcoholic fatty liver disease (NAFLD). Our objective was to analyse the impact of glucocorticoid replacement therapy on the development of NAFLD and NAFLD-related fibrosis and, therefore, on cardiovascular as well as hepatic morbidity in patients with adrenal insufficiency. Two hundred and fifteen individuals with primary (n = 111) or secondary (n = 104) adrenal insufficiency were investigated for hepatic steatosis and fibrosis using the fatty liver index (FLI), NAFLD fibrosis score (NAFLD-FS), Fibrosis-4 Index (FiB-4) plus sonographic transient elastography. Results were correlated with glucocorticoid doses and cardiometabolic risk parameters. The median dose of hydrocortisone equivalent was 20 mg daily, with a median therapy duration of 15 years. The presence and grade of hepatic steatosis and fibrosis were significantly correlated with cardiometabolic risk factors. We could not find any significant correlations between single, daily or cumulative doses of glucocorticoids and the grade of liver steatosis, nor with fibrosis measured via validated sonographic techniques. In patients with adrenal insufficiency, glucocorticoid replacement within a physiological range of 15-25 mg hydrocortisone equivalent per day does not appear to pose an additional risk for the development of NAFLD, subsequent liver fibrosis, or the cardiovascular morbidity associated with these conditions.

Acute abdominal pain due to atypical bilateral adrenal infarction in acute myeloid leukemia with alterations related to myelodysplasia: A case report

Key Clinical Message

Acute myeloid leukemia (AML) can cause acute abdomen following adrenal insufficiency or adrenal infarction. Therefore, when diffusely enlarged adrenal glands and adrenal insufficiency of unknown cause are seen in a patient presenting with acute abdomen, adrenal infarction due to AML, or other hematologic diseases should be ruled out.

Abstract

A 49-year-old man developed acute abdominal pain following adrenal insufficiency and was diagnosed with acute myeloid leukemia (AML) with myelodysplasia-related changes. Because AML can cause acute abdominal pain due to adrenal infarction following adrenal insufficiency, a patient with these conditions should be ruled out adrenal infarction due to AML or other hematologic diseases.

Developing oral chronotherapy for cortisol replacement in congenital adrenal hyperplasia

The sun imposes a 24-h periodicity to life and circadian rhythms have evolved to maintain homoeostasis through the day/night cycle. In humans, there is a central clock that controls the sleep/wake cycle which is paralleled metabolically by a fast/feed cycle. The clock maintains homoeostasis by synchronising metabolism to the time of feeding. Loss of synchrony between the clock and hormonal rhythms results in loss of homoeostasis as evidenced by obesity, depression, and diabetes in people undertaking shift work. Cortisol has a distinct circadian rhythm; peaking on waking and low at sleep onset. Loss of this rhythm in adrenal insufficiency is associated with a poor quality of life and increased mortality. To replace the cortisol rhythm requires chronotherapy and for this you need to define the key parameters of the target rhythm, create a formulation to replicate that rhythm, and then prove clinical benefit. The physiology of hormones is more complex than that of nonnative drugs. Hormones are secreted with varied rhythms, bound to multiple cognate binding proteins, and actively transported and cleared through enzymatic pathways in multiple organs. We have examined the diurnal rhythm of cortisol in healthy volunteers, created physiologically-based pharmacokinetic models, and tested various oral delayed and sustained formulations of hydrocortisone (development name, Chronocort) in clinical trials. The outcome from this work was the manufacture of modified-release hydrocortisone hard capsules (tradename Efmody, Diurnal Ltd), that replicate the cortisol diurnal rhythm and improve the disease control of congenital adrenal hyperplasia the commonest hereditary form of adrenal insufficiency.

Statin treatment is not associated with an increased risk of adrenal insufficiency in real-world setting

Introduction

Statins could reduce the synthesis of steroid hormones, thereby could cause adrenal insufficiency. We investigated this risk in a large nationwide database.

Methods

We conducted a nested case-control study using a cohort of individuals affiliated to the French health insurance system in 2010, ≥18y and without adrenal insufficiency history. Each case had a first event of adrenal insufficiency between 2015 and 2017 and was matched to up to ten controls on age, sex, and prior treatment with corticosteroids. Statin exposure was measured over the five years preceding the index date, considering a six-month censoring lag-time. Association was estimated using a conditional logistic regression adjusted for confounders included in a disease risk score. Analyses were stratified on age, sex and corticosteroid history of use.

Results

4 492 cases of adrenal insufficiency were compared with 44 798 controls (median age 66y, 58% women), of which 39% vs. 33% were exposed to statins, respectively. No association between statin use and adrenal insufficiency was found when adjusting the model for confounders (adjusted odds ratio 0.98; 95% confidence interval 0.90-1.05). These results were consistent regardless of the exposure definition and stratifications considered.

Conclusion

Statin-related adrenal insufficiency risk, if any, seems to be very limited and does not compromise the benefit of statin treatment.

Adrenal Gland Necrosis in Pregnancy: How to Manage? Case Series at Nantes University Hospital and Literature Review

Adrenal necrosis is a rare but serious cause of abdominal pain of thrombotic origin during pregnancy. There is often a delay in diagnosis and treatment. The objective was to specify the clinical and paraclinical signs suggestive of adrenal necrosis, making it possible to improve the delay in diagnostic. The secondary objective was to establish a multidisciplinary protocol regarding management. This is a case report of pregnant women with a radiological diagnosis of adrenal gland necrosis. In parallel, we carried out a systematic review in the same period. We studied these patients' clinical, biological and radiological data. We included eight patients with a computed tomography scan diagnosis of adrenal necrosis and fifteen articles in the literature describing twenty-four cases. All the patients presented with the same symptoms. The treatment was based on curative anticoagulation. The diagnosis of adrenal gland necrosis is worth suggesting in view of the array of sudden morphine-resistant abdominal pain associated with a biological inflammatory syndrome. The diagnosis is based on the computed tomography scan. Three to six months of curative anticoagulation is recommended as well as a thrombophilia and endocrinological assessment to rule out adrenal insufficiency.

Altered Emotion Perception Linked to Structural Brain Differences in Youth With Congenital Adrenal Hyperplasia

CONTEXT

Congenital adrenal hyperplasia (CAH) is a genetic disorder that results in hormonal imbalances and decreased brain volumes in regions important for emotional processing.

OBJECTIVE

To examine whether emotion perception differs between youth with CAH and control youth, and if these differences relate to brain volumes.

METHODS

In this cross-sectional study of 27 youths with CAH (mean age = 12.63 years, 16 female) and 35 age- and sex-matched controls (mean age = 13.03 years, 20 female), each participant rated picture stimuli and completed a 3T structural brain scan. Valence and arousal ratings and reaction times of 61 affective images were assessed. Gray matter volumes were measured by MRI.

RESULTS

Youth with CAH had lower valence ratings for negative (P = .007) and neutral (P = .019) images. Controls showed differences in reaction times and arousal ratings across stimuli conditions, but youth with CAH did not. Brain volumes of the right amygdala (P = .025) and left hippocampus (P = .002) were associated with valence ratings. Left rostral middle frontal (P < .001) and right medial orbitofrontal cortex (P = .002) volumes were negatively related to valence scores only in youth with CAH, whereas left medial orbitofrontal cortex (P < .001) volumes were associated with valence scores positively in youth with CAH and negatively in controls.

CONCLUSION

Findings suggest that youth with CAH perceive emotive stimuli as more unpleasant. Decreased brain volumes in the amygdala, hippocampus, and prefrontal cortex are associated with these measures of altered emotion perception in youth with CAH.

A 65-Year-Old Man with Bilateral Adrenal Hemorrhage Following Prophylaxis for Postoperative Deep Vein Thrombosis with Rivaroxaban

BACKGROUND Direct oral anticoagulant (DOAC) agents, such as rivaroxaban, treat and prevent venous thrombosis. Although adrenal hemorrhage due to DOACs has previously been reported, this is a rare condition that can present as an emergency. In this case report, we present a 65-year-old man who recently had bilateral knee arthroplasty and was started on rivaroxaban 10 mg daily for deep vein thrombosis (DVT) prophylaxis following the surgery. CASE REPORT Ten days after bilateral knee arthroplasty and starting rivaroxaban, the patient presented to the Emergency Department with severe, sudden abdominal pain. Abdominal computed tomography detected significantly enlarged bilateral adrenals, with ill-defined heterogeneous density extending to the upper part of perinephric and paranephric spaces, suggesting bilateral adrenal hemorrhage. A cosyntropin stimulation test was used to confirm the suspicion of adrenal insufficiency. Cortisol levels were 66 nmol/L before stimulation and 83 nmol/L 60 min after cosyntropin administration. Hydrocortisone was started intravenously at a dose of 50 mg every 8 h. After his symptoms improved, he was discharged on oral hydrocortisone at 10 mg in the morning and 5 mg in the evening. Seven weeks after discharge, follow-up abdominal ultrasonography showed that the bilateral adrenal hemorrhage had resolved. CONCLUSIONS This case supports previous cases of adrenal hemorrhage as a rare but serious association with rivaroxaban and highlights the importance of rapid diagnosis using imaging and monitoring of patients for this possible adverse effect. Practitioners must remain vigilant when prescribing anticoagulation therapy, especially in patients who are at an increased risk for adrenal hemorrhage.

Coxsackie B Virus-Induced Cardiac Tamponade and Adrenal Insufficiency

We report a case involving a young male patient without a significant medical history who exhibited symptoms of fatigue, shortness of breath, chest and back pain, and syncope with vomiting. He was found to have adrenal insufficiency and cardiac tamponade requiring pericardiocentesis. Further inpatient workup revealed the patient had positive IgM and IgG antibody titers for the coxsackie B virus, which we believe caused his presentation. The coxsackie B virus strain can cause mild gastrointestinal to more severe cardiac and neurological complications, including meningitis and myocarditis. On rare occasions, the virus can appear in an unexpected fashion, such as in cardiac tamponade or hormonal disruption. This case raises attention to the broad manifestations of the virus and recognizing its more uncommon presentations.

A Case of Disseminated Histoplasmosis Presenting As Adrenal Insufficiency With Granulomatous Hepatitis

Histoplasmosis is a fungal infection caused by Histoplasma capsulatum. In the United States, histoplasmosis is endemic in the Mississippi River Valley and Ohio. Histoplasmosis is often asymptomatic in immunocompetent individuals, and severe disseminated cases are more often seen in immunosuppressed patients. Disseminated histoplasmosis often affects the reticuloendothelial system, invading specific visceral organs such as the liver, spleen, and pancreas. The current study presents a unique case of disseminated histoplasmosis in a 64-year-old immunocompetent male. The patient's presentation included a 40-lb weight loss over a year, bilateral adrenal nodules, abnormal liver enzymes, and granulomatous hepatitis, which initially raised suspicion of a malignant etiology. An adrenal mass biopsy showed fungal morphology that confirmed an H. capsulatum infection. Further history showed that the patient recently traveled to Bangladesh, which is thought to be a region endemic to histoplasmosis. This case is noteworthy because disseminated histoplasmosis rarely affects immunocompetent individuals, and an infectious etiology for adrenal insufficiency is exceedingly rare, especially in the United States. The treatment regimen included a 14-day induction therapy of IV amphotericin B followed by outpatient itraconazole, leading to symptom resolution. This case highlights the need to consider an infectious etiology for adrenal insufficiency, especially among immunocompetent individuals who may be at risk after traveling to endemic areas.

Novel heterozygous variants in the EP300 gene cause Rubinstein-Taybi syndrome 2: Reports from two Chinese children

BACKGROUND

Rubinstein-Taybi syndrome (RSTS) is a rare autosomal-dominant genetic disease caused by variants of CREBBP (RSTS1) or EP300 (RSTS2) gene. RSTS2 is much less common, with less than 200 reported cases worldwide to date. More reports are still needed to increase the understanding of its clinical manifestations and genetic characteristics.

METHODS

The clinical data of two children with RSTS2 were analyzed retrospectively, and their clinical manifestations, auxiliary examinations, and mutational spectrum were summarized. Liquid chromatography-tandem mass spectrometer (LC-MS/MS) technology was used to detect the levels of steroid hormones if possible.

RESULTS

After analyzing the clinical and genetic characteristics of two boys with RSTS2 (0.7 and 10.4 years old, respectively) admitted in our hospital, we identified two novel heterozygous variants in the EP300 exon 22 (c.3750C > A, p. Cys1250*, pathogenic; c.1889A > G, p. Tyr630Cys, likely pathogenic), which could account for their phenotype. In addition to common clinical manifestations such as special facial features, microcephaly, growth retardation, intellectual disability, speech delay, congenital heart defect, recurrent respiratory infections, and immunodeficiency, we found one of them had a rare feature of adrenal insufficiency, and LC-MS/MS detection showed an overall decrease in steroid hormones.

CONCLUSION

In our study, we identified two novel variants in the EP300 exon 22, and for the first time, we reported a case of RSTS2 associated with adrenal insufficiency, which will enrich the clinical and mutational spectrum of this syndrome.

Assessment of the hypothalamic-pituitary-adrenocortical axis function using a vasopressin stimulation test in neonatal foals

BACKGROUND

Bacterial sepsis is the leading cause of death in foals and is associated with hypothalamic-pituitary-adrenocortical axis (HPAA) dysfunction. HPAA function can be evaluated by an arginine-vasopressin (AVP) stimulation test.

HYPOTHESES/OBJECTIVES

Administration of AVP will stimulate a dose-dependent rise in systemic adrenocorticotropin-releasing hormone (ACTH) and cortisol in neonatal foals. There will be no response seen in corticotropin-releasing hormone (CRH) and baseline AVP will be within reference interval.

ANIMALS

Twelve neonatal foals, <72 hours old.

METHODS

HPAA function was assessed in foals utilizing 3 doses of AVP (2.5, 5, and 7.5 IU), administered between 24 and 48 hours of age in this randomized cross-over study. Cortisol, ACTH, CRH and AVP were measured at 0 (baseline), 15, 30, 60 and 90 minutes after AVP administration with immunoassays. The fold increase in cortisol and ACTH was calculated at 15 and 30 minutes compared to baseline.

RESULTS

All doses of AVP resulted in a significant increase in cortisol concentration over time, and a dose-dependent increase in ACTH concentration over time. ACTH and cortisol were significantly increased at 15 and 30 minutes, respectively after all 3 doses of AVP compared to baseline (P < .01). There was no change in endogenous CRH after stimulation with AVP.

CONCLUSION AND CLINICAL IMPORTANCE

Administration of AVP is safe and results in a significant rise in ACTH and cortisol in neonatal foals. A stimulation test with AVP (5 IU) can be considered for HPAA assessment in septic foals.

Transplantation of porcine adrenal spheroids for the treatment of adrenal insufficiency

Primary adrenal insufficiency is a life-threatening disorder, which requires lifelong hormone replacement therapy. Transplantation of xenogeneic adrenal cells is a potential alternative approach for the treatment of adrenal insufficiency. For a successful outcome of this replacement therapy, transplanted cells should provide adequate hormone secretion and respond to adrenal physiological stimuli. Here, we describe the generation and characterization of primary porcine adrenal spheroids capable of replacing the function of adrenal glands in vivo. Cells within the spheroids morphologically resembled adult adrenocortical cells and synthesized and secreted adrenal steroid hormones in a regulated manner. Moreover, the embedding of the spheroids in alginate led to the formation of cellular elongations of steroidogenic cells migrating centripetally towards the inner part of the slab, similar to zona Fasciculata cells in the intact organ. Finally, transplantation of adrenal spheroids in adrenalectomized SCID mice reversed the adrenal insufficiency phenotype, which significantly improved animals' survival. Overall, such adrenal models could be employed for disease modeling and drug testing, and represent the first step toward potential clinical trials in the future.

Changes of androgen and corticosterone metabolites excretion and conversion in cystic fibrosis

Cystic fibrosis (CF) is a life-threatening inherited disease related to a mutation in the CFTR gene, that leads to serious health complications such as chronic pulmonary infections, pancreatic insufficiency, dysfunction of the sweat glands and reproductive system. For the first time, we have described the profile of corticosterone and androgen metabolites in urine, as well as the activity of enzymes involved in steroid genesis and metabolism in people with CF, using gas chromatography/mass spectrometry. A significant reduction in the excretion of most of the measured metabolites in CF was found. These differences were observed in the group of progestagen metabolites, as well as among metabolites of corticosterone and androgens. We revealed higher activities of 17β-hydroxysteroid dehydrogenase and 17,20-lyase in the Δ4 pathway compared with controls, what can promote the androgen synthesis through the backdoor androgen pathway. We have also found the increased conversion activity of 11-oxyganated steroids by 5a-reductase in backdoor pathway. Levels of the most potent and vital androgens (testosterone and dihydrotestosterone) are comparable in both groups. However, the excretion of dehydroepiandrosterone was lower in CF. Decreased cholesterol lipoprotein levels may contribute to limited intracellular cholesterol supply and reduced adrenal steroidogenesis in CF individuals. Changes in the activity of some steroidogenesis enzymes may suggest the presence of some peripheral adaptive mechanisms in CF to maintain androgen balance in the body despite the limited sufficiency of secretion by the adrenal cortex.

Mineralocorticoid replacement therapy in salt-wasting congenital adrenal hyperplasia

Patients with salt-wasting congenital adrenal hyperplasia (SW-CAH) usually show pronounced impairment of aldosterone secretion and, therefore, also require mineralocorticoid replacement. While a lot of research and discussion focusses on the glucocorticoid therapy in SW-CAH to replace the missing cortisol and to control adrenal androgen excess, very little research is dealing with mineralocorticoid replacement. However, recent data demonstrated an increased cardiovascular risk in adult CAH patients urging to reflect also on the current mineralocorticoid replacement therapy. In this review, we explain the role and function of the mineralocorticoid receptor, its ligands and inhibitors and its relevance for the therapy of patients with SW-CAH. We performed an extensive literature search and present data on mineralocorticoid therapy in SW-CAH patients as well as clinical advice how to monitor and optimise mineralocorticoid replacement therapy.

Hypoadrenocorticism in a Dog Following Recovery from Alpha-Amanitin Intoxication

A 10-year-old, female spayed Labrador Retriever was referred for acute hepatopathy and urinary retention. Blood work from the initial presentation (day 0) revealed a severe, mixed hepatopathy. Over the course of the patient's hospitalization, the patient developed liver insufficiency. Urine was submitted for toxicological screening and revealed detection of a trace concentration of alpha-amanitin. The patient was treated supportively for alpha-amanitin intoxication and was discharged from the hospital on day 8, with most biochemical parameters being markedly improved. The patient was persistently hyporexic at the time of discharge. On day 15, at a recheck appointment, the patient had lost 2.4 kg and liver enzymology revealed improved values. On day 24, the patient was presented for anorexia and vomiting and had lost another 2.3 kg. Blood work and endocrinological testing at that time were consistent with hypoadrenocorticism. The patient was started on glucocorticoids and mineralocorticoids. At day 106, the patient was doing well clinically while receiving monthly mineralocorticoids and daily glucocorticoids. This case report is the first to describe the chronological association between alpha-amanitin-induced liver dysfunction and the subsequent development of adrenal insufficiency in a dog.

Machine Learning Approaches for Assessing Risk Factors of Adrenal Insufficiency in Patients Undergoing Immune Checkpoint Inhibitor Therapy

Adrenal insufficiency is a rare, yet life-threatening immune-related adverse event of immune checkpoint inhibitors (ICIs). This study aimed to establish a risk scoring system for adrenal insufficiency in patients receiving anti-programmed cell death 1 (PD-1) or anti-programmed cell death-ligand 1 (PD-L1) agents. Moreover, several machine learning methods were utilized to predict such complications. This study included 209 ICI-treated patients from July 2015 to February 2021, excluding those with prior adrenal insufficiency, previous steroid therapy, or incomplete data to ensure data integrity. Patients were continuously followed up at Gyeongsang National University Hospital, with morning blood samples taken for basal cortisol level measurements, facilitating a comprehensive analysis of their adrenal insufficiency risk. Using a chi-squared test and logistic regression model, we derived the odds ratio and adjusted odds ratio (AOR) through univariate and multivariable analyses. This study utilized machine learning algorithms, such as decision trees, random forests, support vector machines (SVM), and logistic regression to predict adrenal insufficiency in patients treated with ICIs. The performance of each algorithm was evaluated using metrics like accuracy, sensitivity, specificity, precision, and the area under the receiver operating characteristic curve (AUROC), ensuring rigorous assessment and reproducibility. A risk scoring system was developed from the multivariable and machine learning analyses. In a multivariable analysis, proton pump inhibitors (PPIs) (AOR 4.5), and α-blockers (AOR 6.0) were significant risk factors for adrenal insufficiency after adjusting for confounders. Among the machine learning models, logistic regression and elastic net showed good predictions, with AUROC values of 0.75 (0.61-0.90) and 0.76 (0.64-0.89), respectively. Based on multivariable and machine learning analyses, females (1 point), age ≥ 65 (1 point), PPIs (1 point), α-blockers (2 points), and antipsychotics (3 points) were integrated into the risk scoring system. From the logistic regression curve, patients with 0, 1, 2, 4, 5, and 6 points showed approximately 1.1%, 2.8%, 7.3%, 17.6%, 36.8%, 61.3%, and 81.2% risk for adrenal insufficiency, respectively. The application of our scoring system could prove beneficial in patient assessment and clinical decision-making while administering PD-1/PD-L1 inhibitors.

Autoimmune diseases and their prevalence in Saudi Arabian patients with type 1 diabetes mellitus

OBJECTIVES

To evaluate the prevalence of autoimmune disorders among young and adult populations diagnosed with type 1 diabetes mellitus (T1DM) in Al-Madinah Al-Munawarah, Saudi Arabia, and assess the potential impact of these conditions on other comorbidities.

METHODS

A retrospective, descriptive study examined autoimmune disorders in T1DM youth and adults. A total of 2258 verified T1DMs were tested. Analyzed hospital and laboratory data. Autoimmune T1DM was investigated clinically and laboratory.

RESULTS

A total of 2258 T1DM adults, adolescents, and children were investigated; 500 (22.2%) were under 12, 540 (23.9%) were 13-17, and 1218 (53.9%) were 18 plus. Autoimmune with T1DM was 67.4%. Gender and age affect prevalence. 25.7% of adult females had autoimmune thyroiditis. Children and adolescents have greater rates of celiac disease than adults of both genders. Adrenal insufficiency was more frequent in adults. Adult males had 28.5% polyglandular autoimmune diseases, and women had 19.7%. Type 1 DM and other autoimmune illnesses increase the risk of nephropathy, CVD, and hypoglycemia. Bloodstream biomarkers linked to these disorders corroborate this.

CONCLUSION

Autoimmune diseases in Saudi patients with T1DM exhibited specificity with respect to gender and age. Al-Madinah Al-Munawwarah have a heightened prevalence of autoimmune diseases among young individuals diagnosed with T1DM, such as celiac disease and autoimmune thyroiditis. Conversely, older individuals in the region have been observed to exhibit a greater incidence of adrenal failure and polyglandular autoimmune disorders. Autoimmune diseases that result in nephropathy, CVD, and hypoglycemia are highly prevalent based on biomarker levels.

A case of iatrogenic Cushing syndrome and subsequent adrenal insufficiency from a hidden ingredient in the supplement Artri Ajo King

Dietary supplement use is common in the United States. Supplements are regulated by the US Food and Drug Administration (FDA) under a separate set of guidelines from typical food and drug products. This case report describes a patient who presented to the emergency department (ED) with abdominal pain, vomiting, and generalized weakness. On detailed history, we learned that he had been taking a supplement called Artri Ajo King for 18 months, followed by recent abrupt cessation before his ED presentation. He was subsequently found to have a low serum cortisol level and was diagnosed with secondary adrenal insufficiency by a cosyntropin stimulation test. Ultimately, he was started on hydrocortisone with resolution of his symptoms. This case illustrates the consequence of allowing dietary supplements to be sold before FDA evaluation as well as the importance of physicians eliciting history of supplement use and offering a culturally competent discussion with their patients regarding supplement use.

Differentiation of human adipose tissue-derived mesenchymal stromal cells into steroidogenic cells by adenovirus-mediated overexpression of NR5A1 and implantation into adrenal insufficient mice

BACKGROUND AIMS

Cell therapy for adrenal insufficiency is a potential method for physiological glucocorticoid and mineralocorticoid replacement. We have previously shown that mouse mesenchymal stromal cells (MSCs) differentiated into steroidogenic cells by the viral vector-mediated overexpression of nuclear receptor subfamily 5 group A member 1 (NR5A1), an essential regulator of steroidogenesis, and their implantation extended the survival of bilateral adrenalectomized (bADX) mice.

METHODS

In this study, we examined the capability of NR5A1-induced steroidogenic cells prepared from human adipose tissue-derived MSCs (MSC [AT]) and the therapeutic effect of the implantation of human NR5A1-induced steroidogenic cells into immunodeficient bADX mice.

RESULTS

Human NR5A1-induced steroidogenic cells secreted adrenal and gonadal steroids and exhibited responsiveness to adrenocorticotropic hormone and angiotensin II in vitro. In vivo, the survival time of bADX mice implanted with NR5A1-induced steroidogenic cells was significantly prolonged compared with that of bADX mice implanted with control MSC (AT). Serum cortisol levels, which indicate hormone secretion from the graft, were detected in bADX mice implanted with steroidogenic cells.

CONCLUSIONS

This is the first report to demonstrate steroid replacement by the implantation of steroid-producing cells derived from human MSC (AT). These results indicate the potential of human MSC (AT) to be a source of steroid hormone-producing cells.

A Conspectus of Euvolemic Hyponatremia, Its Various Etiologies, and Treatment Modalities: A Comprehensive Review of the Literature

Hyponatremia is the most prevalent electrolyte imbalance encountered among hospitalized patients, athletes, the elderly, patients with chronic ailments, postoperative patients, and a few asymptomatic individuals. Clinical manifestations of hyponatremia can be diverse, with characteristic neurological symptoms. Depending on in-depth medical history, physical examination (including volume status assessment), laboratory investigation, and drug history, patients can be classified broadly as undergoing hypervolemic, euvolemic, or hypovolemic hyponatremia. However, patients with hypervolemic hyponatremia often present with distinctive signs such as edema or ascites, and the clinical presentation of hypovolemic and euvolemic hyponatremia poses significant challenges for clinicians. The convolution in clinical manifestations of patients is due to the varied etiologies of euvolemic hyponatremia, such as syndrome of inappropriate antidiuretic hormone secretion (SIADH), adrenocortical insufficiency, hypothyroidism, psychogenic polydipsia, different classes of drugs (chemotherapeutics, antipsychotics, antidepressants), endurance exercise events, and reset osmostat syndrome (ROS). The management of hyponatremia depends on the rate of hyponatremia onset, duration, severity of symptoms, levels of serum sodium, and underlying comorbidities. Over the last decade, the clinical understanding of hyponatremia has been scattered due to the introduction of innovative laboratory markers and new drugs. This article will be a conspectus of all the recent advancements in the field of diagnosis, investigations, management, and associations of hyponatremia, along with traditional clinical practices. Subsequently, a holistic overview has been laid out for the clinicians to better understand and identify knowledge deficiencies on this topic.
