Prevalence of Chronic Complications, Their Risk Factors, and the Cardiovascular Risk Factors among Patients with Type 2 Diabetes Attending the Diabetic Clinic at a Tertiary Care Hospital in Sri Lanka

Prevalence of chronic diabetic complications and associated risk factors among follow-up diabetic patients: estimates from a referral national diabetes center in Yemen

BACKGROUND

Emergence and progression of diabetic complications are associated with several risk factors. Identifying these risk factors related to diabetes helps avoid such complications and develop preventive measures to protect patients and improve their quality of life. This study aimed to estimate the prevalence of chronic complications among Yemeni diabetic patients and investigate the associations between these complications, sociodemographic characteristics, and diabetic risk factors.

METHODS

This cross-sectional study was conducted at the National Diabetic Referral Center in Sana'a, Yemen, from September 1 to October 30, 2023. Of the 228 respondents, 222 were considered valid for analysis. Data for this study were collected using the World Health Organization (WHO) STEPS Surveillance questionnaire and a simple physical assessment. IBM SPSS version 24.0 was utilized to manage and analyze the data. Descriptive statistics were used to determine the prevalence of diabetes complications. The chi-square test and binary logistic regression were used to determine the associations and risk factors. A p-value of less than 0.05 was used to determine statistical significance.

RESULTS

Diabetes-related complications were reported by 62.6% of respondents, with females having a greater risk of diabetic foot, nephropathy, and retinopathy, while males had an increased risk of neuropathy complications. Unemployment, obesity, non-adherence to diabetes regimens, uncontrolled hypertension, longer duration of type 1 diabetes (T1DM), and irregular physician check-ups were identified as key predictors of diabetes-related complications. Administration of statins as lipid-lowering medications was associated with a reduced risk of coronary artery disease (CAD) or ischemic stroke complications.

CONCLUSION

Chronic complications related to diabetes were common among patients in Yemen. Factors such as unemployment, obesity, non-adherence to diabetes regimens, uncontrolled hypertension, longer duration of T1DM, and irregular physician check-ups were identified as key predictors of these complications. Implementation of the WHO non-communicable disease package is strongly recommended. This package comprises comprehensive measures aimed at detecting, treating, preventing, and controlling diabetic complications and ultimately improving the overall management of diabetes in Yemen.

Prevalence, patterns, and determinants of vascular complications of type 2 diabetes in a teaching hospital in Addis Ababa, Ethiopia: a retrospective study

BACKGROUND

Patients with type 2 diabetes mellitus (T2D) have an increased risk of vascular complications. Despite the rise in the prevalence of T2D and its complications throughout the globe, there is a paucity of data regarding the prevalence and determinants of vascular complications of T2D in Ethiopia. Hence, this study aimed to assess the prevalence, patterns, and determinants of the microvascular and macrovascular complications of T2D among adult patients attending a teaching hospital in Addis Ababa, Ethiopia.

METHODS

A retrospective study was done by reviewing the electronic health records of adult patients with T2D attending the general medical and endocrine referral clinics of Yekatit 12 Hospital Medical College, Addis Ababa, Ethiopia, from June 1, 2023, to November 30, 2023. Statistical Package for Social Sciences (SPSS), version 25, was used to analyze the data. Descriptive analysis was used to summarize the sociodemographic, clinical, and laboratory profiles as well as the patterns of vascular complications of T2D. Bivariate and multivariate logistic regression models were fitted, and the crude odds ratio (COR) and adjusted odds ratio (AOR), together with the 95% confidence interval (CI), were computed to identify the determinants of microvascular and macrovascular complications of T2D.

RESULTS

A total of 272 patients with T2D were included in this study; 50.5% were females, and the mean (± standard deviation) age was 56.3 ± 12.8 years. The majority of patients (62.5%) had diabetes for ≥ 5 years. More than half (51.5%) had poor glycemic control with glycated haemoglobin (HbA1c) value of ≥ 7%. The overall prevalence of vascular complications was 39%. The prevalence of microvascular complications was 23.5%, the most common being neuropathy (11.8%), and the prevalence of macrovascular complications was 21%, the most common being coronary artery disease (12.1%). The determinants of microvascular complications were age ≥ 60 years (AOR = 2.25, 95% CI: 1.17, 4.33), diabetes duration of ≥ 5 years (5-10 years [AOR = 3.13, 95% CI: 1.37, 7.18], and > 10 years [AOR = 3.88, 95% CI: 1.66, 9.06], and HbA1c value of ≥ 7% (AOR = 2.21, 95% CI: 1.14, 4.28). The odds of developing macrovascular complications were higher with diabetes duration of ≥ 5 to 10 years (AOR = 2.89, 95% CI: 1.37, 6.12) as compared with diabetes duration of < 5 years.

CONCLUSIONS

This study demonstrated a high prevalence of microvascular and macrovascular complications in adult patients with T2D. Older age, prolonged duration of diabetes, and poor glycemic control were identified as the determinants for the development of microvascular complications  of T2D, while prolonged duration of diabetes was the determining factor for the development of macrovascular complications. Hence, targeted initiatives are required to enhance the prevention and early detection of vascular complications of T2D in resource-limited countries like Ethiopia.

Epidemiology and Burden of Peripheral Artery Disease in People With Type 2 Diabetes: A Systematic Literature Review

Type 2 diabetes (T2D) and lower-extremity peripheral artery disease (PAD) are growing global health problems associated with considerable cardiovascular (CV) and limb-related morbidity and mortality, poor quality of life and high healthcare resource use and costs. Diabetes is a well-known risk factor for PAD, and the occurrence of PAD in people with T2D further increases the risk of long-term complications. As the available evidence is primarily focused on the overall PAD population, we undertook a systematic review to describe the burden of comorbid PAD in people with T2D. The MEDLINE, Embase and Cochrane Library databases were searched for studies including people with T2D and comorbid PAD published from 2012 to November 2021, with no restriction on PAD definition, study design or country. Hand searching of conference proceedings, reference lists of included publications and relevant identified reviews and global burden of disease reports complemented the searches. We identified 86 eligible studies, mostly observational and conducted in Asia and Europe, presenting data on the epidemiology (n = 62) and on the clinical (n = 29), humanistic (n = 12) and economic burden (n = 12) of PAD in people with T2D. The most common definition of PAD relied on ankle-brachial index values ≤ 0.9 (alone or with other parameters). Incidence and prevalence varied substantially across studies; nonetheless, four large multinational randomised controlled trials found that 12.5%-22% of people with T2D had comorbid PAD. The presence of PAD in people with T2D was a major cause of lower-limb and CV complications and of all-cause and CV mortality. Overall, PAD was associated with poor quality of life, and with substantial healthcare resource use and costs. To our knowledge, this systematic review provides the most comprehensive overview of the evidence on the burden of PAD in people with T2D to date. In this population, there is an urgent unmet need for disease-modifying agents to improve outcomes.

The effect of lifestyle factors on chronic complications of diabetes at public health hospitals in Southwest Ethiopia

Ethiopia faces a significant challenge with increasing non-communicable diseases like diabetes, ranking among the top four in sub-Saharan Africa. However, there is a lack of research on how lifestyle affects chronic complications of diabetes in Ethiopia, highlighting the need for urgent exploration to develop better intervention strategies. This study aimed to evaluate the link between lifestyle factors and chronic complications of diabetes in public health hospitals in Southwest Ethiopia. A cross-sectional study involving 389 diabetes patients from Mizan-Tepi University Teaching Hospital (MTUTH) and Gebretsadik Shawo General Hospital (GSGH) in Southwest Ethiopia was conducted. Data collection methods included interviewer-administered questionnaires, patient medical record reviews, physical examination, and serum analysis. SPSS version 25 was used for data analysis, including descriptive statistics and bivariate and multivariate logistic regression analyses. Statistical significance was determined at a p-value < 0.05. The study revealed a 32.1% prevalence of chronic complications of diabetes, with 13.4% having chronic kidney disease, 8.0% experiencing visual disturbances, and 16.7% suffering from peripheral sensory pain. After adjusting for confounding variables, age (41-60 years [AOR = 1.77; 95% CI 1.01, 3.15] and > 60 years [AOR = 2.18; 95% CI 1.20, 4.33]), duration of diabetes mellitus (> 6 years [AOR = 2.90; 95% CI 1.74, 4.85]), alcohol consumption [AOR = 2.30; 95% CI 1.33, 3.98], physical inactivity [AOR = 2.43; 95% CI 1.38, 4.27], and body mass index (underweight [AOR = 7.66; 95% CI 1.68, 34.8] and obese [AOR = 3.53; 95% CI 1.84, 10.5]) were significantly associated with chronic complications of diabetes. Chronic complications of diabetes are a major problem in the study area. Lifestyle factors strongly influence chronic diabetes complications, highlighting the importance of preventive measures. Implementing health education and prevention programs focusing on modifiable lifestyle factors is crucial.

Predictors of microvascular complications in patients with type 2 diabetes mellitus at regional referral hospitals in the central zone, Tanzania: a cross-sectional study

Microvascular complications encompass a group of diseases which result from long-standing chronic effect of diabetes mellitus (DM). We aimed to determine the prevalence of microvascular complications and associated risk factors among patients with type 2 diabetes mellitus (T2DM). A cross-sectional analytical hospital-based study was conducted at Singida and Dodoma regional referral hospitals in Tanzania from December 2021 to September 2022. A total of 422 patients with T2DM were included in the analysis by determining the prevalence of microvascular complications and their predictors using multivariable logistic regression analysis. A two-tailed p value less than 0.05 was considered statistically significant. The prevalence of microvascular complications was 57.6% (n = 243) and diabetic retinopathy was the most common microvascular complication which accounted for 21.1% (n = 89). Having irregular physical activity (AOR = 7.27, 95% CI = 2.98-17.71, p < 0.001), never having physical activity (AOR = 2.38, 95% CI = 1.4-4.01, p = 0.013), being hypertensive (AOR = 5.0, 95% CI = 2.14-11.68, p = 0.030), having T2DM for more than 5 years (AOR = 2.74, 95% CI = 1.42-5.26, p = 0.025), being obese (AOR = 2.63, 95% CI = 1.22-5.68, p = 0.010), and taking anti-diabetic drugs irregularly (AOR = 1.94, 95% CI = 0.15-0.77, p < 0.001) were the predictors of microvascular complications. This study has revealed a significant proportion of microvascular complications in a cohort of patients with T2DM. Lack of regular physical activity, being obese, taking anti-diabetic drugs irregularly, presence of hypertension, and long-standing duration of the disease, were significantly associated with microvascular complications.

Control of cardiometabolic risk factors and their association with carotid intima media thickness among patients with type 2 diabetes mellitus-single center experience in a developing country

Background/aim

Type 2 diabetes mellitus (T2DM) is closely associated with atherosclerotic cardiovascular diseases (ASCVD). The objective of this study was to describe the degree of ASCVD risk factor control and their association with carotid intima-media thickness (CIMT) in T2DM patients followed up at a diabetes clinic in Southern, Sri Lanka.

Materials and methods

A crosssectional study was conducted to examine the association between CIMT and nonalcoholic fatty liver disease (NAFLD)in 300 T2DM patients. Both CIMT and its associations with modifiable cardiometabolic risk factors were examined using ultrasonography. The recommended optimal targets for risk factors were defined as glycated hemoglobin (HbA1C) < 7 %, absence of NAFLD, albumin-to-creatinine ratio (ACR) < 30 mg, triglyceride (TG) < 150 mg/dL, low-density lipoprotein cholesterol (LDL-C) < 100 mg/dL, high-density lipoprotein cholesterol (HDL-C) in men > 40 and in women > 50 mg/dL, systolic blood pressure (SBP) < 130 mmHg, and diastolic blood pressure (DBP) < 80 mmHg.

Results

SBP, DBP, LDL-C, TG, HDL-C, HbA1C, and ACR were optimally controlled in 59.3%, 75.0%, 46.7%, 84.3%, 46.0%, 33.0%, and 18.7% of patients, respectively. Notably, nearly half of the study subjects did not have NAFLD. Only three patients (1%) had achieved all therapeutic targets. There were statistically significant differences in CIMT between optimally controlled TG and suboptimally controlled TG group (p = 0.027) and between the groups with and without NAFLD (p = 0.045) when adjusted for age and duration of diabetes. CIMT showed significant and positive associations with LDL-C (p = 0.024), TG (p = 0.026), and NAFLD (p = 0.005). Among these, the presence of NAFLD had the highest odds of having higher CIMT when compared to LDL-C and TG.

Conclusion

The majority of patients have not achieved the recommended targets for ASCVD risk factors and are at high risk of ASCVD. It is therefore necessary to identify the reasons for not achieving the treatment targets in order to reduce the ASCVD burden by controlling LDL-C, TG, and NAFLD.

Time-dependent impact of type 2 diabetes mellitus on incident prodromal Alzheimer disease: A longitudinal study in 1395 participants

BACKGROUND AND PURPOSE

This study was undertaken to investigate the longitudinal impact of type 2 diabetes mellitus (T2DM) on the prodromal and dementia stages of Alzheimer disease (AD), focusing on diabetes duration and other comorbidities.

METHODS

A total of 1395 dementia-free individuals aged 55-90 years with maximum 15-year follow-up data were enrolled from the Alzheimer's Disease Neuroimaging Initiative database. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) of the incidence of prodromal or dementia stages of AD.

RESULTS

Longer T2DM duration (≥5 years; multiadjusted HR = 2.19, 95% confidence interval [CI] = 1.05-4.58), but not shorter T2DM duration (<5 years), was associated with a significantly increased risk of incident prodromal AD over a mean follow-up of 4.8 years. APOE ε4 allele (HR = 3.32, 95% CI = 1.41-7.79) and comorbid coronary artery disease (CAD; HR = 3.20, 95% CI = 1.29-7.95) further increased the risk of incident prodromal AD in patients with T2DM. No significant association was observed between T2DM and the risk of progression from prodromal AD to AD dementia.

CONCLUSIONS

T2DM, which is characterized by a longer duration, increases the incidence risk of prodromal AD but not AD dementia. APOE ε4 allele and comorbid CAD strengthen the relationship between T2DM and prodromal AD. These findings highlight T2DM characteristics and its comorbidities as predictors for accurate prediction of AD and screening of at-risk populations.

Systolic blood pressure reduction with tirzepatide in patients with type 2 diabetes: insights from SURPASS clinical program

BACKGROUND

Tirzepatide, a once-weekly glucose-dependent insulinotropic polypeptide/ glucagon-like peptide-1 receptor agonist, is approved in the United States, Europe and Japan for the treatment of type 2 diabetes. Across the SURPASS-1 to -5 clinical studies, tirzepatide 5, 10 and 15 mg demonstrated significant improvements in glycated haemoglobin A1c (HbA1c) (- 1.9 to - 2.6%), body weight (- 6.6 to - 13.9%) and systolic blood pressure (SBP) (- 2.8 to - 12.6 mmHg) at the end of study treatment.

METHODS

Post-hoc mediation analyses were conducted to evaluate weight-loss dependent and weight-loss independent effects of tirzepatide on SBP reductions across the 5 SURPASS studies. The safety population (all randomized patients who took at least 1 dose of study drug) of each study was analyzed. Additional analyses were conducted at individual study level or pooled across 5 SURPASS trials.

RESULTS

The difference in mean SBP change from baseline at 40 weeks (total effect) between the tirzepatide and comparator groups was - 1.3 to - 5.1 mmHg (tirzepatide 5 mg), - 1.7 to - 6.5 mmHg (tirzepatide 10 mg) and - 3.1 to - 11.5 mmHg (tirzepatide 15 mg). These SBP reductions were primarily mediated through weight loss, with different degrees of contributions from weight-loss independent effects across the different trials. In the SURPASS-4 study, which enrolled patients with established cardiovascular disease, weight-loss independent effects explained 33% to 57% of difference in SBP change between tirzepatide and insulin glargine groups. In a pooled analysis of the SURPASS-1 to -5 studies, there was a significant (p < 0.001) but weak correlation (r = 0.18 to 0.22) between change in body weight and SBP. Reductions in SBP with tirzepatide were not dependent on concomitant antihypertensive medications at baseline as similar reductions were observed whether participants were receiving them or not (interaction p = 0.77). The largest SBP reductions were observed in the highest baseline category (> 140 mmHg), while those in the first quartile of baseline SBP category (< 122 mmHg) observed no further decrease in SBP.

CONCLUSIONS

Tirzepatide-induced SBP reduction was primarily mediated through weight loss, with different degrees of contributions from weight-loss independent effects across the different trials. SBP reduction was not dependent on antihypertensive medication use but dependent on baseline SBP value, alleviating theoretical concerns of hypotension.

Diabetes mellitus: what the neurologists need to know

Diabetes mellitus is a common condition associated with numerous complications and comorbidities. The diabetes spectrum includes type 1, type 2 and other forms of diabetes, which may be associated with medical therapies and genetic factors. Type 2 diabetes is managed with lifestyle, oral therapies, non-insulin-based injectables and subsequently insulin. Type 1 diabetes requires insulin from the time of diagnosis. In recent years, there have been considerable developments in the therapies available to treat type 2 diabetes and some of these also afford cardiorenal protection. This review summarises the nature, complications and therapeutic advances in the field of diabetes and provides a concise review for neurologists. Managing diabetes optimally prevents complications and all medical specialties need a basic understanding of the principles involved in diabetes care.

Investigating the prevalence of diabetic complications in overweight/obese patients: a study in a tertiary hospital in Malaysia

Background

In Malaysia, although diabetes accounts for more than 70% of all deaths, it is unclear how it relates to BMI and diabetic complications. This study aimed to investigate the prevalence of obesity and diabetic complications among diabetic patients in Malaysia.

Materials and methods

A cross-sectional study using an existing clinical registry was performed from 1 January 2020 to 31 December 2020 at Hospital Serdang, Malaysia. Adult patients with type 2 diabetes mellitus had their medical records examined for disease complications, as reported by the patient at first contact with the DMTAC pharmacist.

Results

The study comprised a total of 495 participants with an average HbA1c of 10.5%. About 91% (n = 451) of the 495 patients were obese/overweight. Around 37.8% (n = 187) of diabetic patients are between the ages of 50 and 59, and 59% (n = 292) have had diabetes for less than 10 years. A total of 8.5% (n = 42) and 9.7% (n = 48) consume alcohol and smoke, respectively. Around 29.9% (n = 148) had one other comorbidity (hypertension or dyslipidemia), and 63.4% (n = 314) had two comorbidities. Regarding the prevalence of complications, there were 18.9% (n = 94) who had myocardial infarction, 11.1% (n = 55) who had stroke, and 9% (n = 45) who had CKD. Age (adjusted OR = 1.03; 95% CI 1.00 to 1.07; p = 0.041) and hypertension (adjusted OR = 4.06; 95% CI 1.21 to 13.60; p = 0.023) were significantly related with the prevalence of complications in patients with diabetes.

Conclusion

In our study, a BMI of more than 23 kg/m2 (obese/overweight) does not seem to be associated with the prevalence of complications. Age and hypertension, on the other hand, appear to be strong risk predictors of the incidence of complications. With the understanding of the recent outlook on diabetes, it is recommended that public education on the targeted population should be encouraged to negate these complications.

Prevalence of Cardiovascular Risk Factors Among Patients With Diabetes Mellitus Type 2 at King Fahad University Hospital, Saudi Arabia

Background

Diabetes mellitus is considered a major risk factor for cardiovascular diseases. Patients with diabetes mellitus type 2 (DM-II) are at twice as high risk for the development of cardiovascular diseases than the general population. Thus, we aimed to assess the most prevalent cardiovascular risk (CVR) factors among DM-II patients in the Eastern province of Saudi Arabia.

Method

This is a cross-sectional, retrospective, and observational study conducted on DM-II patients at King Fahad University Hospital (KFUH) Al Khobar, Saudi Arabia, from January 2016 to December 2021. The total number of participants was 373 who were patients with DM-II. The patients' demographic information (age, sex, marital status, height, weight, body mass index (BMI), waist, hip circumference, and waist-hip ratio were calculated or obtained from hospital electronic records as were the CVR factors, age, gender, smoking habits, physical activity, BMI, haemodynamic measurements, glycosylated haemoglobin (HbA1C) levels and lipid profile.

The collected data were analyzed by using SPSS Statistics v.28 (IBM Corp., Armonk, NY). The descriptive statistics were reported using mean±SD for numerical data and relative frequencies (%) for categorical data. P < 0.05 were counted significant. Quantitative data were analyzed using the ANOVA test to compare the means of the three groups. Qualitative data were analyzed and compared using the chi-square test. Fisher’s exact test was also used to study the statistical significance of variables. Spearman rank correlation was used to study the relationship between HbA1C and other CV risk factors. 

Results

The mean age was 58 (± 13) years; females were 57% of the sample. Around 92% were smokers, 84% had a sedentary lifestyle, 72% had dyslipidemia, 58% were obese, 30% were overweight, 58% reported poorly control of their diabetes, 50% had hypertension and 32% had pre-hypertension. Furthermore, 89% of participants had two or more CVR factors other than DM-II. We found a significant association between high body mass index, dyslipidemia, high systolic blood pressure and pulse pressure (p<0.05) with HbA1C.

Conclusion

The majority of participants had two or more cardiovascular risk factors in addition to DM-II. Poor control of DM-II and cardiovascular risk factors cannot be ignored and primary to tertiary prevention must be the top priority when managing the diabetic population in order to prevent devastating outcomes and progression of reversible morbidity.

Poor Self-Care Practices and Being Urban Resident Strongly Predict Chronic Complications Among Patients with Type 2 Diabetes in Eastern Ethiopia: A Hospital-Based Cross-Sectional Study

Background

Diabetes, together with its complications, has a considerable negative influence on people's quality of life and healthcare delivery and raises diabetic mortality. However, there is limited information about the diabetes-associated chronic complications in the study setting. Therefore, this study aimed to determine the burden and factors related to the chronic complications among patients with type 2 diabetes (T2D) in Eastern Ethiopia.

Methods

A hospital-based cross-sectional study was conducted among 879 patients with T2D at two public hospitals in Harar. The data were collected through interviews using a structured questionnaire. Data related to the diagnosis of chronic complications and biochemical tests were extracted from medical records. The outcome variable was the number of chronic complications that happened to the patients. A generalized Poisson regression model with robust variance estimation was used to investigate the association of independent variables with chronic complications. An adjusted prevalence ratio with a 95% CI was reported to show an association using a p-value ≤0.05.

Results

One or more chronic complications were presented in 43% of T2D (95% CI: 39.65, 46.19). Macrovascular and microvascular complications were found in 27.6% and 23.5% of patients, respectively. Urban residence (APR = 2.64; 95% CI: 1.54, 4.54), low wealth status (APR = 1.80; 95% CI: 1.17, 2.76), diabetes duration ≥5 years (APR = 1.46; 95% CI: 1.05, 2.01), hypertriglyceridemia (APR = 1.48; 95% CI: 1.07, 2.09) and poor self-care practices (APR = 1.62; 95% CI: 1.18, 2.23) were factors significantly associated with the chronic complications.

Conclusion

The burden of chronic complications was high, with nearly half of T2D patients experiencing one or more chronic complications. Almost one in ten patients suffered from multiple chronic complications. The complications were mainly influenced by being urban resident, low wealth status, and poor self-care practices. Therefore, health care providers need to educate patients and promote self-care practices and healthy lifestyles to achieve treatment goals and lower the risk of chronic complications.

SUBCLINICAL HYPOTHYROIDISM AS A CONTRIBUTOR TO MACROVASCULAR COMPLICATIONS IN PATIENTS WITH TYPE 2 DIABETES MELLITUS

This study aimed to evaluate changes of the lipid panel data in patients with comorbid type 2 diabetes mellitus (T2DM) and subclinical hypothyroidism (SCH) and to identify the probable prognostic values of the lipid profile for macrovascular complication (MVC) development. The study included 370 patients presented with only T2DM and 30 patients suffering from both T2DM and SCH. Receiver operating characteristic (ROC) analysis was used to identify prognostically significant values of the lipid profile with the optimal ratio of sensitivity and specificity for MVC development. All lipid profile values in the patients with T2DM combined with SCH were significantly higher compared to those with only T2DM. At the same time, SCH + T2DM increased the risk of exceeding target levels of triglycerides by 2.9 times and HDL-C by 4.1 times. Analysis of lipid profile values according to macrovascular involvement showed that total cholesterol, LDL-C and non-HDL-C in patients with T2DM and SCH were significantly higher compared to those with only T2DM. The levels of triglycerides >1.65 mmol/L, non-HDL-C >3.74 mmol/L and remnant cholesterol >0.74 mmol/L determined by the ROC analysis can be used for stratification of patients with T2DM combined with SCH into the category of increased risk of MVC development.

Personalized Type 2 Diabetes Management: An Update on Recent Advances and Recommendations

Previous guidelines for the treatment of people with type 2 diabetes mellitus (T2D) have relied heavily upon rigid algorithms for the sequential addition of pharmacotherapies to achieve target glycemic control. More recent guidelines advocate a personalized approach for diabetes treatment, to improve patient satisfaction, quality of life, medication adherence and overall health outcomes. Clinicians should work with patients to develop personalized goals for their treatment, including targeted glycemic control, weight management, prevention and treatment of associated comorbidities and avoidance of complications such as hypoglycemia. Factors that affect the intensity of treatment and choice of pharmacotherapy should include medical and patient influences. Medical considerations include the diabetes phenotype, biomarkers including genetic tests, and the presence of comorbidities such as cardiovascular, renal, or hepatic disease. Patient factors include their treatment preference, age and life expectancy, diabetes duration, hypoglycemia fear and unawareness, psychological and social circumstances. The use of a personalized approach in the management of people with T2D can reduce the cost and failure associated with the algorithmic "one-size-fits-all" approach, to anticipate disease progression, improve the response to diabetes pharmacotherapy and reduce the incidence of diabetes-associated complications. Ultimately, the use of personalized medicine in people with T2D should improve medication adherence, patient satisfaction and quality of life to reduce diabetes distress and improve physical health outcomes.

Chronic-Care-Management Programs for Multimorbid Patients with Diabetes in Europe: A Scoping Review with the Aim to Identify the Best Practice

AIM

This scoping review is aimed at providing a current descriptive overview of care programs based on the chronic care model (CCM) according to E. H. Wagner. The evaluation is carried out within Europe and assesses the methodology and comparability of the studies.

METHODS

A systematic search in the databases PubMed, Embase, and MEDLINE via OVID was conducted. In the beginning, 2309 articles were found and 48 full texts were examined, 19 of which were incorporated. Included were CCM-based programs from Belgium, Cyprus, Germany, Italy, Switzerland, and the Netherlands. All 19 articles were presented descriptively whereof 11 articles were finally evaluated in a checklist by Rothe et al. (2020). In this paper, the studies were tabulated and evaluated conforming to the same criteria.

RESULTS

Due to the complexity of the CCM and the heterogeneity of the studies in terms of setting and implementation, a direct comparison proved difficult. Nevertheless, the review shows that CCM was successfully implemented in various care situations and also can be useful in single practices, which often dominate the primary care sector in many European health systems. The present review was able to provide a comprehensive overview of the current care situation of chronically ill patients with multimorbidities.

CONCLUSIONS

A unified nomenclature concerning the distinction between disease management programs and CCM-based programs should be aimed for. Similarly, homogeneous quality standards and a Europe-wide evaluation strategy would be necessary to identify best practice models and to provide better care for the steadily growing number of chronically multimorbid patients.

Microvascular complications and its predictors among type 2 diabetes mellitus patients at Dessie town hospitals, Ethiopia

BACKGROUND

Diabetes mellitus is a serious metabolic disorder which becomes common in middle and low incomes countries since few decades. Microvascular complications include retinopathy, neuropathy and nephropathy all of which can lead to disability, dependency, accelerate their morbidity, and mortality. In Ethiopia, there is paucity data regarding this topic. Hence, this study aimed to assess prevalence of microvascular complications and its predictors among type 2 diabetes mellitus patients.

METHODS

Cross-sectional study was conducted from February to March 2020 at Dessie town hospitals. We used simple random sampling to recruit study participants and pre-tested interviewer administered questionnaire to collect the data. Data was entered into Epi-Data 3.1 and exported to SPSS-23 for analysis. Binary logistic regression was done to select potential variables to be adjusted at p ≤ 0.25. After running multivariable regression, variables with a p-value ≤ 0.05 were declared as statistically significant.

RESULTS

Three hundred and thirty-five type 2 DM patients participated in the study, of which 54.6% were males. One hundred and twenty-seven [37.9% (95% CI 32.5%-43.3%)] of diabetes mellitus had at least one microvascular complications. These were retinopathy 24.8%, nephropathy 16.1%, and neuropathy 8.1%. Age 60-87 years (AOR = 2.76, 95% CI 1.02-7.46), duration of diabetes > 5 years (AOR = 4.09, 95% CI 2.40-6.96), mellitus and co-morbid hypertension (AOR = 3.52, 95% CI 2.09-5.95), were statistically significant.

CONCLUSIONS

In this study, diabetic microvascular complications are prevalent. Increasing the age of participants, longer duration of diabetes mellitus and co-morbid hypertension were independent predictors. Health workers should give emphasis for diabetes mellitus through early screening and health education, abrupt medication for aged patients with long duration of diabetes mellitus, and hypertension, and also early detection and management of microvascular complication.

Single Nucleotide Polymorphism rs17173608 in the Chemerin Encoding Gene: Is It a Predictor of Insulin Resistance and Severity of Coronary Artery Disease in Non-Obese Type 2 Diabetes?

(1) Background: Chemerin, or the RARRES2 (Retinoic Acid Receptor Responder 2) gene, is found to be associated with an increased incidence of insulin resistance, endothelial dysfunction, type 2 diabetes (T2D), and coronary artery disease (CAD). This study investigates associations of RARRES2rs17173608 with insulin resistance and the severity of CAD in non-obese T2D patients in relation to the clinical and genetic factors. (2) Methods: A total of 300 patients with T2D and CAD were recruited in this study. The associations of insulin resistance and the severity of CAD with RARRES2rs17173608 and clinical factors were assessed. The genotyping procedures were performed using the TaqMan method. The significant associations (p ≤ 0.05) from preliminary tests were employed to carry out the secondary analysis. (3) Results: RARRES2rs17173608 (TT, TG, and GG polymorphisms in the preliminary analysis; TG and GG polymorphisms in a secondary analysis) was associated with insulin resistance and the severity of CAD in both the preliminary and secondary analysis (all p-values were < 0.05). Additionally, in the secondary analysis, FPG and ACEI were also associated with insulin resistance and the severity of CAD (all p-values were < 0.05). (4) Conclusion: From the preliminary findings, rs17173608 is a significant predictor of insulin resistance and the severity of CAD.

Incidence of Cardiovascular Complications and Nephropathy in Patients with Type 2 Diabetes in a Primary Care Setting in Riyadh, Saudi Arabia

BACKGROUND

Diabetes mellitus is prevalent in Saudi Arabia. Our study aims to estimate the rate and time of developing macrovascular and microvascular complications in diabetic patients in a primary care setting.

METHODOLOGY

This is a retrospective cohort study. All collected data were retrieved using medical files and the electronic patient records of all diabetics having regular follow-ups in Family Medicine clinics, King Faisal Specialist Hospital & Research Centre in Riyadh, Saudi Arabia, from the beginning of January 2002 to the end of December 2018. The data included the demographics of patients diagnosed with diabetes mellitus, their HbA1c, and the follow-up duration of the development of complications, which included cardiovascular complications and diabetic nephropathy.

RESULTS

We included 365 patients, of whom 47.1% males and 52.9% were females. The mean age of diabetes mellitus diagnosis in our population was 50 years (SD±11.3). The mean duration of follow-up was 7.14 years (SD±3.9). The rate of developing cardiovascular complications and diabetic nephropathy was 11.2% and 10.4%, respectively. The mean time to develop cardiovascular complications and diabetic nephropathy was 6 (SD±3.9) and 5.24 (SD±3.2) years, respectively. The mean time to develop the first diabetes complication was 5.5 years (SD±3.6). There was no statistical significance in the mean of HbA1c between patients who developed diabetic complications and those who did not.

CONCLUSION

Diabetes complications are common in the Saudi community. The duration of the development of cardiovascular complications and diabetic nephropathy was shorter than that indicated in international and national reports. Robust screening programs to diagnose and improve the control of diabetes mellitus should be established in the Kingdom.

Active screening of patients with diabetes mellitus for pulmonary tuberculosis in a tertiary care hospital in Sri Lanka

End TB strategy by the WHO suggest active screening of high-risk populations for tuberculosis (TB) to improve case detection. Present study generates evidence for the effectiveness of screening patients with diabetes mellitus (DM) for Pulmonary TB (PTB). A study was conducted among 4548 systematically recruited patients over 45 years attending DM clinic at the National Hospital of Sri Lanka. The study units followed an algorithm specifying TB symptom and risk factor screening for all, followed by investigations and clinical assessments for those indicated. Bacteriologically confirmed or clinically diagnosed PTB were presented as proportions with 95% CI. Mean (SD) age was 62·5 (29·1) years. Among patients who completed all indicated steps of algorithm, 3500 (76·9%) were investigated and 127 (2·8%) underwent clinical assessment. Proportion of bacteriologically confirmed PTB patients was 0·1% (n = 6,95%CI = 0·0-0·3%). None were detected clinically. Analysis revealed PTB detection rates among males aged ≥60 years with HbA1c ≥ 8 to be 0·4% (n = 2, 95%CI = 0·0-1·4%). The study concludes that active screening for PTB among all DM patients at clinic settings in Sri Lanka, to be non-effective measure to enhance TB case finding. However, the sub-category of diabetic males with uncontrolled diabetics who are over 60 years of age is recommended as an option to consider for active screening for PTB.

Correlations of sialic acid with glycated hemoglobin A1c and glycemia in postmenopausal women with type-2 diabetes mellitus

For women in the postmenopausal period, age-related changes in the hormonal status are associated with a higher risk for type-2 diabetes and its complications. The tissue injury caused by diabetic vascular complications can induce a release of sialic acid (SA) into the general circulation leading to increased levels. The present study is a cross-sectional single center study of 77 women in the postmenopausal period. The subjects selected for the study were divided into two groups: i) The control group, which included postmenopausal women without type-2 diabetes mellitus (n=27); and ii) a group of postmenopausal women diagnosed with type-2 diabetes (n=50). By analyzing how the serum values of SA were correlated with glycemia and glycated hemoglobin in the subjects with diabetes, it was determined that both parameters exhibited a strong positive correlation (P<0.0001) in the group with type-2 diabetes. Therefore, SA may be considered as a potential marker for the screening, diagnosis or prognosis of type-2 diabetes for postmenopausal women.

Prevalence, Patterns and Predictors of Chronic Complications of Diabetes Mellitus at a Large Referral Hospital in Ethiopia: A Prospective Observational Study

PURPOSE

Diabetes mellitus complications are responsible for increased disability, morbidity, and mortality. This study aimed to assess prevalence, patterns, and predictors of chronic complications of diabetes among people with diabetes.

PATIENTS AND METHODS

The study was conducted using a prospective observational study design which was done on people with diabetes attending the ambulatory clinic of Mettu Karl Referral Hospital. The data were collected using a consecutive type of sampling technique from April 15 to August 9, 2019. The data were entered into Epidata manager version 4.4.2. Logistic regression analysis was done to identify predictors of chronic complications of diabetes.

RESULTS

A total of 330 participants were included in this study. The mean age of participants was 49.9±14.2, and 156 (47.3%) were 41 to 60 years old. About 127 (38.5%) had one or more chronic complications. The predictors of chronic diabetes complications were resident in urban areas [AOR: 1.94; 95% CI: (1.17, 3.20); p = 0.010], duration of diabetes 10 years [AOR: 2.05, 95% CI: (1.21, 3.47); p = 0.007], hypertension [AOR: 4.19; 95% CI: (2.54, 6.91); p < 0.001] and poor glycemic control [AOR: 2.82; 95% CI: (1.53, 5.21); p = 0.001].

CONCLUSION

Almost two-fifth of the study participants had chronic complications of diabetes. Residents in urban areas, longer duration of diabetes, hypertension and poor glycemic control were predictors of chronic diabetes complications. It is important to achieve good glycemic control and manage comorbid diseases like hypertension to minimize the risk of chronic diabetes complications.

Clinical outcome and determinants of amputation in a large cohort of Iranian patients with diabetic foot ulcers

OBJECTIVE

Determining the predictive factors of diabetes foot ulcer (DFU) development and lower extremity amputations (LEA) in patients with diabetes mellitus (DM) is of great importance to compose risk stratification models. The aim of this study is to investigate the outcome and predictors of LEA in patients with DFU in large sample of Iranian patients.

METHODS

This prospective cohort study was conducted during a 2-year period from 2014 to 2016, in Shiraz, southern Iran. All the patients with type 1 and 2 DM and DFU were included in the cohort and were followed for 2 years at least. They were visited in the clinic on a monthly basis and development of new DFU and LEA were recorded. The two-year free-DFU survival and predictors of the DFU development and LEA were recorded. Multivariate regression models were used to determine the factors.

RESULTS

A total number of 432 patients with mean age of 56.8 ± 13.3 years were included. The two-year DFU-free survival rate was 0.826. The two-year DFU-free survival was associated with male gender (p = 0.005), foot deformity (p = 0.002), history of prior DFU (p < 0.001), cigarette smoking (p = 0.032), nephropathy (p = 0.005), retinopathy (p = 0.007), ischemic heart disease (p = 0.043), and neuropathy (p < 0.001).

CONCLUSION

Development of new DFU is associated with higher age, longer duration of disease, and type I diabetes. LEA was associated with increased white blood cell (WBC), Creatinine and ulcer history for major amputation and ulcer history, fasting blood sugar (FBS), infection, revascularization history, and foot deformity, for minor amputation.

Correlation Between Extracutaneous Microvascular Complications and Diabetic Foot Ulcers in Patients with Type 2 Diabetes Mellitus

BACKGROUND

Diabetes is a metabolic disease that is taking an epidemic proportion around the world. The occurrence of microvascular complications and diabetic foot ulcer is associated with an increased mortality and morbidity incidence, which is the most serious complication of this disease, which significantly reduce the quality of patient life.

OBJECTIVE

The aim of the study was to determine the correlation of extracutaneous microvascular complications with diabetic foot ulcer in patients with type 2 diabetes.

METHOD

The study was prospective, and included 160 patients with type 2 diabetes. It was conducted at the University Clinical Center of the Republic of Srpska in the period from January 2016 until December 2019. The respondents were adults, of both sexes, suffering from type 2 diabetes, in whom complications of this disease are present. Glycemic control was established based on a target HbA1c value of 7%.

RESULTS

Of the 160 patients in the study, 53.8% were men and 46.2% were women. The average age of the patients was 70.11%±10.05 years. Extracutaneous microvascular complications were present in 85 patients (53.1%); of which 30.2% had well-regulated glycemia (HbA1c≤7.0%), while 61.5% (p<0.001) had unregulated glycemia (HbA1c≥7.0). Polyneuropathy was present in 23.3% of patients with HbA1c≤7.0%, while 41.0% of patients had HbA1c≥7.0% (p<0.043). Nephropathy with HbA1c≤7.0% was present in 36.8% of cases compared to patients with HbA1c≥7.0 in whom the prevalence was 36.8% (p<0.004). Out of total, 25.6% had retinopathy with HbA1c≤7.0%, while in 41.9% of patients with HbA1c≥7.0% (p <0.067). Diabetic ulcer foot was present in 13 patients with HbA1c≥7 (11.1%) compared to patients with HbA1c≤7.0% where there was no occurrence of this complication 0.0% (p<0.021). At the same time, 5.6% of patients had a diabetic foot ulcer with polyneuropathy (p=0.010), 4.4% had neuropathy (p=0.058) and 5.6% had retinopathy (p=0.014).

CONCLUSION

The high incidence of extracutaneous microvascular complications and diabetic foot ulcer in patients with type 2 diabetes requires a multidisciplinary approach of medical professionals that includes prevention of risk factors and good regulation of glycemia.

Prevalence of Vascular Complications Among Type 2 Diabetic Patients in a Rural Health Center in South India

Introduction: Vascular complications are the major cause of morbidity in patients with diabetes mellitus. Screening for these complications is crucial in early detection and tertiary prevention. Hence, this study aimed at finding the prevalence of micro and macrovascular complications and their associated factors in type 2 diabetes mellitus patients in a rural health center by using simple and easily available tools. Methodology: This hospital based cross sectional study was conducted in Rural Health and Training Centre (RHTC) of Sri Ramachandra medical college from Jan 2017 to Aug 2017. All type 2 diabetes patients registered at RHTC were included in the study. By the use of questionnaire, clinical examination and laboratory investigations, the prevalence of macro and microvascular complications and associated factors were ascertained. Multiple logistic regression was used to identify factors associated with vascular complications of diabetes. Results: The study included 390 type 2 diabetes patients. The overall prevalence of macrovascular and microvascular complications in our study population was 29.7% and 52.1%, respectively. Among the macrovascular complications, both coronary artery disease (CAD) and peripheral vascular disease (PVD) had a prevalence rate of 15.1%. Among the microvascular complications, peripheral neuropathy (44.9%) had the highest prevalence followed by nephropathy (12.1%) and diabetic foot (7.2%). Multiple logistic regression analyses showed high HbA1c level, lower education, high postprandial blood sugar, hypertension, abdominal obesity were significantly associated with increased risk of vascular complications of diabetes. Conclusion: This study demonstrated the increased prevalence of vascular complications in Type 2 diabetes patients in rural India. Regular screening to identify those patients at risk could prevent further progression of complications.

Long-Term Cilostazol Treatment and Predictive Factors on Outcomes of Endovascular Intervention in Patients with Diabetes Mellitus and Critical Limb Ischemia

INTRODUCTION

Despite improvements in endovascular interventions and multidisciplinary approaches, improving clinical outcomes and increasing limb salvage have become increasingly challenging. This prospective study investigated the associations of cilostazol treatment with clinical outcomes and predictive factors in patients with diabetes mellitus (DM) and critical limb ischemia (CLI) after endovascular revascularization of the affected angiosome.

METHODS

In this study, 172 consecutive patients with CLI (Fontaine levels III-IV) received cilostazol treatment after successful endovascular intervention according to the angiosome concept, and their primary patency rates and cardiovascular and amputation events during a 24-month follow-up period were assessed.

RESULT

The 24-month primary patency rate, mortality rate, and amputation rate were better in the patients under long-term cilostazol treatment (P < 0.001, P = 0.029, and P = 0.014). Weighted multivariate Cox analyses with a propensity scoring-based method showed that long-term cilostazol treatment [hazard ratio (HR) 0.2, 95% confidence interval (CI) 0.11-0.36, P < 0.001], direct revascularization (DR) (HR 0.46, 95% CI 0.28-0.74, P = 0.002), and supervised exercise (HR 0.4, 95% CI 0.24-0.66, P < 0.001) were independently associated with primary patency. Patients with lower-extremity amputation (LEA) had a higher risk of coronary artery disease (CAD) and mortality. Cellulitis and neuropathy were independently associated with LEA events (cellulitis: HR 2.89, 95% CI 1.66-5.05, P < 0.001; neuropathy: HR 2.2, 95% CI 1.31-3.7, P = 0.003).

CONCLUSION

Our results showed that patients with DM who received cilostazol treatment for more than 3 months had significantly better outcomes and decreased amputation and mortality rates after DR, and cellulitis and neuropathy were highly associated with the risk of limb loss. A large-scale randomized trial should be conducted in the future to confirm these results.

Prevalence and associated factors of vascular complications among inpatients with type 2 diabetes: A retrospective database study at a tertiary care department, Ningbo, China

To determine the prevalence of vascular complications among inpatients with type 2 diabetes mellitus (T2DM) and factors independently associated with vascular complications in a tertiary care department in Ningbo, China, the authors conducted a cross-sectional study using an existing computerised medical records database. A total of 3370 adult patients with T2DM were admitted to this tertiary care department for the first time between 2012 and 2017. Patients were categorised as those (1) with at least one vascular complication, (2) with at least one microvascular complication, and (3) with at least one macrovascular complication. Over 5 years, the prevalence of vascular, microvascular, and macrovascular complications among inpatients with T2DM was 73.2%, 57.5%, and 51.4%, respectively. The odds of vascular, microvascular, and macrovascular complications increased with age and were higher in patients with hypertension. The odds of vascular and microvascular complications were higher in single, divorced, or widowed patients, patients with T2DM for a long time, and patients on advanced T2DM therapeutic regimen. The odds of vascular and macrovascular complications were lower in women. The odds of microvascular complications decreased with education. The odds of macrovascular complications were higher in smokers. In conclusion, in the tertiary care department, more than half of inpatients with T2DM had vascular complications, and factors independently associated with vascular complications were identified. The study findings could be used in future interventional studies to prevent and manage vascular complications among these patients.

Multistate Models to Predict Development of Late Complications of Type 2 Diabetes in an Open Cohort Study

BACKGROUND

Increase in the prevalence of type 2 diabetic mellitus (T2DM) as a complex disease, its complications, and spread has become a dominant global health threat in recent decades.

OBJECTIVE

The aim of the current study was to investigate the impact of risk factors and transition probability on the development and progression of the late complications of T2DM.

METHODS

This study was an open cohort one which was conducted at Isfahan Endocrine and Metabolism Research Center (IEMRC). The data were collected from 1993 to 2018. The sample size consisted of 2519 adults diagnosed with type 2 diabetes. We applied the homogeneous multistate models including no complication, retinopathy alone, coronary artery disease (CAD), microalbuminuria, retinopathy and CAD, and the final absorbing mortality states.

RESULTS

Based on our results, time-varying hypertension strongly intensified the hazard of transition to mortality in CAD, no complication, CAD and retinopathy, and retinopathy patients by 4.99, 4.09, 3.42, and 2.65 times, respectively. Hypertension seemed to be a potential factor for the transition of microalbuminuria to no complication in diabetic patients. One-unit increase in LDL increased the hazard ratio of transition from CAD, and retinopathy and CAD to mortality by 1.8% and 2.4%, respectively. Moreover, one level increase in time-varying HbA1c increased the hazard ratio of transition to retinopathy and mortality among no complication diabetic patients by 30% and 67%, respectively. One level increase in time-varying HbA1c also intensified the hazard ratio of transition from retinopathy to mortality by 45%. The same level of increase in time-varying HbA1c also intensified the hazard ratio of transition from CAD alone to CAD and retinopathy, and microalbuminuria to retinopathy by 26% and 50%, respectively.

CONCLUSION

In addition to glycemic control, our study indicates that controlling hypertension and hyperlipidemia is more effective in reducing mortality and the diabetic macro- and microvascular complications.

Gene Lifestyle Interactions With Relation to Obesity, Cardiometabolic, and Cardiovascular Traits Among South Asians

The rapid rise of obesity, type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD) during the last few decades among South Asians has been largely attributed to a major shift in lifestyles including physical inactivity, unhealthy dietary patterns, and an overall pattern of sedentary lifestyle. Genetic predisposition to these cardiometabolic risk factors may have interacted with these obesogenic environments in determining the higher cardiometabolic disease prevalence. Based on the premise that gene-environment interactions cause obesity and cardiometabolic diseases, we systematically searched the literature and considered the knowledge gaps that future studies might fulfill. We identified only seven published studies that focused specifically on gene-environment interactions for cardiometabolic traits in South Asians, most of which were limited by relatively small sample and lack of replication. Some studies reported that the differences in metabolic response to higher physical activity and low caloric diet might be modified by genetic risk related to these cardiometabolic traits. Although studies on gene lifestyle interactions in cardiometabolic traits report significant interactions, future studies must focus on more precise assessment of lifestyle factors, investigation of a larger set of genetic variants and the application of powerful statistical methods to facilitate translatable approaches. Future studies should also be integrated with findings both using mechanistic studies through laboratory settings and randomized clinical trials for clinical outcomes.

Value of Estimated Glomerular Filtration Rate and Albuminuria in Predicting Cardiovascular Risk in Patients with Type 2 Diabetes without Cardiovascular Disease

Introduction

Onset of nephropathy in patients with type 2 diabetes (T2DM) increases the cardiovascular disease (CVD) risk. Association of the parameters of diabetic nephropathy such as albuminuria and estimated Glomerular filtration rate (eGFR) with predicted CVD risk has not been studied in Sri Lankan patients with T2DM.

Methods

In a cross-sectional study of patients who underwent single visit screening at a diabetes center in Sri Lanka, we obtained demographic and biochemical data. Those with urine albumin excretion over 30 mg/g creatinine were considered as having albuminuria, and eGFR was calculated using modified diet in renal disease (MDRD) formula. Ten-year coronary heart disease risk (CHDR) in all patients was calculated using United Kingdom Prospective Diabetes Study risk engine, and those with CHDR > 10% were considered as having high risk. Spearman correlation was used to study the association between eGFR and CHDR, and logistic regression analysis was carried out to study the association of albuminuria and eGFR with high (>10%) CHDR.

Results

Of the patients with diabetes studied (n=2434), 64% (1563) were males. Mean (SD) age and duration of diabetes were 52 (11) and 9 (3) years, respectively. Normoalbuminuria, microalbuminuria, and macroalbuminuria were observed in 16.4%, 14.8%, and 68.7% of patients, respectively. Three hundred ninety-four (16.2%) patients had eGFR < 60 ml/min. Moderate correlation was observed between eGFR and predicted CHDR [r = (-0.4), P<0.01] and between eGFR and fatal CHDR (FCHDR) [r = (-0.5), P<0.01]. Independent t-test showed that patients with eGFR < 60 ml/min were older and had longer diabetes duration and lesser BMI compared to those who had eGFR > 60 ml/min (P < 0.01). On logistic regression, nephropathy according to eGFR became a strong predictor for high CHDR (OR; 3.497, 95% CI 2.08 to 5.87), and nephropathy according to albuminuria and both albuminuria and eGFR was not significant predictor of CHDR.

Conclusions

Predicted CHDR shows a moderate and significant association with eGFR in patients with T2DM without symptomatic CVD. eGFR is a stronger predictor than albuminuria in predicting high CHDR in patients with T2DM. Intensification of CVD prevention measures should be done more confidently among patients with T2DM and reduced eGFR than in those with albuminuria alone.
