To assess the prevalence and risk factors for early and severe diabetic retinopathy and macular edema in a large cohort of patients with type 2 diabetes Retinopathy grading (any retinopathy, severe retinopathy, diabetic macular edema) and risk factors of 64784 were prospectively recorded between January 2000 and March 2013 and analyzed by Kaplan- Meier analysis and logistic regression. Retinopathy was present in 20.12% of subjects, maculopathy was found in 0.77%. HbA1c > 8%, microalbuminuria, hypertension, BMI > 35 kg/m2 and male sex were significantly associated with any retinopathy, while HbA1c and micro- And macroalbuminuria were the strongest risk predictors for severe retinopathy. Presence of macroalbuminuria increased the risk for DME by 177%. Retinopathy remains a significant clinical problem in patients with type 2 diabetes. Metabolic control and blood pressure are relevant factors amenable to treatment. Concomitant kidney disease identifies high risk patients and should be emphasized in interdisciplinary communication. © 2015 Hammes et al. Source

Aim: To characterize the clinical phenotype of type 2 diabetes mellitus (T2DM) with respect to age, gender, and BMI. Method: Anonymized data of 120 183 people with T2DM from the German/Austrian multicenter Diabetes Patienten Verlaufsdokumentation database were analyzed based on chronological age or age at diagnosis (0-19, 20-39, 40-59, 60-79, and ≥80 years). Age, gender, and BMI comparisons with clinical phenotype were made using χ2 and Kruskal-Wallis tests (SAS V9.2). Results: Of all the patients, 51.3% were male, average age was 67.1±12.7 years, and average disease duration was 9.9±9.1 years. More girls than boys were diagnosed during adolescence and more men than women during adulthood (20-60 years). No gender differences existed when age at diagnosis was ≥60 years. Patients were obese on average (BMI: 30.5±6.1 kg/m2) and had significantly higher BMI values than German population peers. The BMI gap was widest in the younger age categories and closed with increasing age. Adult women were significantly more obese than men. Obese patients more often had elevated HbA1c (≥7.5%), hypertension or dyslipidemia (irrespective of age), microalbuminuria (adults), or retinopathy (elderly) than nonobese patients. More men than women (20-60 years) had hypertension, dyslipidemia, or microalbuminuria while more women than men (≥60 years) had hypertension or dyslipidemia. Conclusion: During puberty, more girls than boys were diagnosed with T2DM while during adulthood males predominated. T2DM manifested at comparatively lower BMI in males, and younger patients were more obese at diagnosis. Age, gender, and BMI were also associated with poor metabolic control and cardiovascular disease comorbidities/complications. © 2012 European Society of Endocrinology. Source

Objective: Several studies suggest benefits of insulin analogues detemir or glulisine in overweight and obese patients with type 2 diabetes. The present multicentre study therefore examines, whether these insulin analogues are used more frequently in patients with increased body mass index. Methods: Data of 38 560 adult type 2 diabetic patients using insulin analogues, from 150 centres in Germany, registered in a standardized, prospective, computer-based documentation program (DPV), were included. Patients were classified into body mass index categories according to World Health Organization. Analysis was stratified by 3 time periods. To adjust for confounding effects, multivariable logistic regression models were created. Results: Detemir was preferentially used in overweight (OR 1.36, 95%-CI 1.20-1.53) and obese patients (OR 2.06, 95%-CI 1.84-2.31) compared to normal-weight patients. These effects remained significant after adjusting for sex, age, new/old federal state of Germany, size of centre, treatment in university clinic and clinic/specialized private practice. Models were additionally adjusted for time period and interaction of BMI category with age or sex. For glulisine, a minor effect was present when comparing obese to normal-weight patients (OR 1.26, 95%-CI 1.06-1.50). After adjustment, this finding was no longer significant. Stratified by obesity grade, class III obese patients more frequently used detemir or glulisine compared to class I obese patients. Comparing time periods, odds ratios did not differ, neither for detemir nor for glulisine. Conclusion: Detemir is used more often in overweight and obese patients compared to normal-weight patients. For glulisine, the relationship is less pronounced. © J. A. Barth Verlag in Georg Thieme Verlag KG Stuttgart New York. Source
