  abstract  = {Aim To assess the prevalence and severity of periodontitis in patients with moderate chronic kidney disease (CKD) and comparing the results with the self-reported periodontitis awareness of the study subjects. Material and methods The periodontal status of 270 patients with moderate CKD randomly selected from a cohort of 5,217 subjects participating in the prospective observational German Chronic Kidney Disease (GCKD) project was analysed by recording bleeding on probing (BOP), probing pocket depth (PPD) and clinical attachment level (CAL). Furthermore, the awareness of the study subjects of their periodontal conditions was evaluated by a self-reported questionnaire. Results 24.4\% of the CKD study patients showed no or only mild signs of periodontal disease, 47.6\% displayed moderate and 27\% severe periodontitis. Questionnaire data revealed that 62.3\% of the study subjects with severe periodontitis were not aware of the presence of the disease, 44.4\% denied having received any systematic periodontal therapy so far, although 50\% of them indicated to visit their dentist regularly for professional tooth cleanings. Conclusion While the clinical study data confirm an increased prevalence of periodontitis in CKD patients, their self-reported awareness of periodontitis was low.},

  abstract  = {Background Diabetes mellitus (DM) is the leading cause of end-stage renal disease. Little is known about practice patterns of anti-diabetic therapy in the presence of chronic kidney disease (CKD) and correlates with glycaemic control. We therefore aimed to analyze current antidiabetic treatment and correlates of metabolic control in a large contemporary prospective cohort of patients with diabetes and CKD. Methods The German Chronic Kidney Disease (GCKD) study enrolled 5217 patients aged 18-74 years with an estimated glomerular filtration rate (eGFR) between 30-60 mL/min/1.73 m2 or proteinuria >0.5 g/d. The use of diet prescription, oral anti-diabetic medication, and insulin was assessed at baseline. HbA1c, measured centrally, was the main outcome measure. Results At baseline, DM was present in 1842 patients (35 \%) and the median HbA1C was 7.0 \% (25th-75th percentile: 6.8-7.9 \%), equalling 53 mmol/mol (51, 63); 24.2 \% of patients received dietary treatment only, 25.5 \% oral antidiabetic drugs but not insulin, 8.4 \% oral antidiabetic drugs with insulin, and 41.8 \% insulin alone. Metformin was used by 18.8 \%. Factors associated with an HbA1C level >7.0 \% (53 mmol/mol) were higher BMI (OR = 1.04 per increase of 1 kg/m2, 95 \% CI 1.02-1.06), hemoglobin (OR = 1.11 per increase of 1 g/dL, 95 \% CI 1.04-1.18), treatment with insulin alone (OR = 5.63, 95 \% CI 4.26-7.45) or in combination with oral antidiabetic agents (OR = 4.23, 95 \% CI 2.77-6.46) but not monotherapy with metformin, DPP-4 inhibitors, or glinides. Conclusions Within the GCKD cohort of patients with CKD stage 3 or overt proteinuria, antidiabetic treatment patterns were highly variable with a remarkably high proportion of more than 50 \% receiving insulin-based therapies. Metabolic control was overall satisfactory, but insulin use was associated with higher HbA1C levels.},
