Abstract
BACKGROUND Immunoglobulin A (IgA) nephropathy (IgAN) treatment consists of maximal supportive care and, for high-risk individuals, immunosuppressive treatment (IST). There are conflicting results regarding IST. Therefore, we aimed to investigate IST results among IgAN patients in Turkiye. METHOD The data of 1656 IgAN patients in the Primary Glomerular Diseases Study of the Turkish Society of Nephrology Glomerular Diseases Study Group were analyzed. A total of 408 primary IgAN patients treated with IST (65.4% male, mean age 38.4 ± 12.5 years, follow-up 30 (3-218) months) were included and divided into two groups according to treatment protocols (isolated corticosteroid [CS] 70.6% and combined IST 29.4%). Treatment responses, associated factors were analyzed. RESULTS Remission (66.7% partial, 33.7% complete) was achieved in 74.7% of patients. Baseline systolic blood pressure, mean arterial pressure, and proteinuria levels were lower in responsives. Remission was achieved at significantly higher rates in the CS group (78% vs. 66.7%, p = 0.016). Partial remission was the prominent remission type. The remission rate was significantly higher among patients with segmental sclerosis compared to those without (60.4% vs. 49%, p = 0.047). In the multivariate analysis, MEST-C S1 (HR 1.43, 95% CI 1.08-1.89, p = 0.013), MEST-C T1 (HR 0.68, 95% CI 0.51-0.91, p = 0.008) and combined IST (HR 0.66, 95% CI 0.49-0.91, p = 0.009) were found to be significant regarding remission. CONCLUSION CS can significantly improve remission in high-risk Turkish IgAN patients, despite the reliance on non-quantitative endpoints for favorable renal outcomes. Key predictors of remission include baseline proteinuria and specific histological markers. It is crucial to carefully weigh the risks and benefits of immunosuppressive therapy for these patients.

Abstract
AIM Renal diseases in diabetes mellitus (DM) patients, include diabetic nephropathies (DN) and non-diabetic renal diseases (NDRD). The clinical differentiation among them is usually not so clear and effective. Aim of this study which examined renal biopsies in patients with type-2 DM was to identify the prevalence and the nature of NDRD. MATERIALS AND METHODS We recorded the clinical and laboratory finding alongside with the histopathological examination of the renal biopsies obtained from 71 type-2 DM patients who underwent renal biopsy in our center. Based on the renal biopsy findings patients were classified into two groups (DN and NDRD) and data was compared between the two groups. RESULTS There were 42 women and 29 men; aged 55 ± 12 years. In patients with DN (n: 34), diabetic retinopathy was more common [16 (47.1 %) vs. 6 (16.2 %) respectively, p =0.01], duration of DM was longer (108.8 ± 58.8 months vs 57.8 ± 55.9 months respectively, p <0.001) and the degree of proteinuria was more severe (6 ± 4.3 g/day vs. 4.5 ± 4.6 g/day respectively, p =0.04) compared to the patients with NDRD. Regression analysis revealed that diabetes duration >60 months, presence of diabetic retinopathy and proteinuria >3.5 g/day were independent predictors of DN with 79.4 % sensitivity and 86.5% specificity. Focal segmental glomerulosclerosis was the most frequent diagnosis in patients with NDRD. CONCLUSIONS The prevalence of NDRD is remarkably frequent in DM patients in whom nephrologists consider renal biopsy an appropriate measure. Short duration of DM, degree of proteinuria and absence of retinopathy were predictors of NDRD. Hippokratia 2015; 19 (2):148-152.
