Background Chronic kidney disease (CKD) is a global public health problem with increasing disease burden affecting nearly 10% of adult population worldwide. We aimed to detect the prevalence of CKD, patients' distribution among CKD stages, and factors associated with having CKD in diabetic patients in Turkey. Methods This cross-sectional study, conducted in 2022, included 1591 patients with diabetes (mean age, 63 +/- 10 years; female: 65.5%) from the Cappadocia Cohort study. CKD was diagnosed by an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m(2) or urinary albumin-to-creatinine ratio (UACR) >= 30 mg/g, which was measured in spot urine samples collected in the morning for three consecutive days. Results In this cohort of adult diabetic patients, the prevalence of CKD was 25.1%. More than half of the diabetic patients with CKD (53.8%) had albuminuria without a decrease in eGFR, 28.1% had decreased eGFR without albuminuria, and 18.2% had both albuminuria and decreased eGFR. While the percentage of CKD patients who are female vs. male was 60% vs. 40%, CKD prevalence was higher in males (29.2%) than in females (22.9%) (P = 0.007). Among patients with CKD, only 9.4% were aware that they had CKD. Age, male sex, HbA1c, triglyceride, uric acid, C-reactive protein, and hypertension Grade 1, 2 and 3 were associated with the presence of CKD, with uric acid showing the strongest association. Conclusions More than half of our patients with CKD would not have been diagnosed if urinary albumin excretion was not measured. Early detection of CKD by regular screening of diabetic patients using both UACR and eGFR measurements is essential for early diagnosis and prompt treatment to slow down disease progression.

BackgroundWe aimed to present the demographic characteristics, clinical presentation, and outcomes of our multicenter cohort of adult KTx recipients with COVID-19.MethodsWe conducted a multicenter, retrospective study using data of patients hospitalized for COVID-19 collected from 34 centers in Turkey. Demographic characteristics, clinical findings, laboratory parameters (hemogram, CRP, AST, ALT, LDH, and ferritin) at admission and follow-up, and treatment strategies were reviewed. Predictors of poor clinical outcomes were analyzed. The primary outcomes were in-hospital mortality and the need for ICU admission. The secondary outcome was composite in-hospital mortality and/or ICU admission.ResultsOne hundred nine patients (male/female: 63/46, mean age: 48.412.4years) were included in the study. Acute kidney injury (AKI) developed in 46 (42.2%) patients, and 4 (3.7%) of the patients required renal replacement therapy (RRT). A total of 22 (20.2%) patients were admitted in the ICU, and 19 (17.4%) patients required invasive mechanical ventilation. 14 (12.8%) of the patients died. Patients who were admitted in the ICU were significantly older (age over 60years) (38.1% vs 14.9%, p=0.016). 23 (21.1%) patients reached to composite outcome and these patients were significantly older (age over 60years) (39.1% vs. 13.9%; p=0.004), and had lower serum albumin (3.4g/dl [2.9-3.8] vs. 3.8g/dl [3.5-4.1], p=0.002), higher serum ferritin (679 mu g/L [184-2260] vs. 331 mu g/L [128-839], p=0.048), and lower lymphocyte counts (700/mu l [460-950] vs. 860 /mu l [545-1385], p=0.018). Multivariable analysis identified presence of ischemic heart disease and initial serum creatinine levels as independent risk factors for mortality, whereas age over 60years and initial serum creatinine levels were independently associated with ICU admission. On analysis for predicting secondary outcome, age above 60 and initial lymphocyte count were found to be independent variables in multivariable analysis.Conclusion Over the age of 60, ischemic heart disease, lymphopenia, poor graft function were independent risk factors for severe COVID-19 in this patient group. Whereas presence of ischemic heart disease and poor graft function were independently associated with mortality.
