Background: We aimed to study the characteristics of peritoneal dialysis (PD) patients with Coronavirus disease-19 (COVID-19), determine the short-term mortality and other medical complications, and delineate the factors associated with COVID-19 outcome. Methods: In this multicenter national study, we included PD patients with confirmed COVID-19 from 27 centers. The baseline demographic, clinical, laboratory, and radiological data and outcomes at the end of the first month were recorded. Results: We enrolled 142 COVID-19 patients (median age:52 years). 58.2% of patients had mild disease at diagnosis. Lung involvement was detected in 60.8% of patients. 83 (58.4%) patients were hospitalized, 31 (21.8%) patients were admitted to intensive care unit and 24 needed mechanical ventilation. 15 (10.5%) patients were switched to hemodialysis and hemodiafiltration was performed for four (2.8%) patients. Persisting pulmonary symptoms (n=27), lower respiratory system infection (n=12), rehospitalization for any reason (n=24), malnutrition (n=6), hypervolemia (n=13), peritonitis (n=7), ultrafiltration failure (n=7) and in PD modality change (n=8) were reported in survivors. 26 patients (18.31%) died in the first month of diagnosis. The non-survivor group was older, comorbidities were more prevalent. Fever, dyspnea, cough, serious-vital disease at presentation, bilateral pulmonary involvement, and pleural effusion were more frequent among non-survivors. Age (OR:1.102; 95%CI: 1.032-1.117; p: 0.004), moderate-severe clinical disease at presentation (OR:26.825; 95%CI: 4.578-157.172; p

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.

Aim: Acute kidney injury (AKI) is a clinical syndrome that can cause disturbances in fluid-electrolyte and acid-base balance, resulting in the accumulation of nitrogen and uremic toxins along with the loss of kidney functions within hours or days. In this study, it was aimed to retrospectively examine patients with acute kidney injury to determine whether there is a relationship between infection parameters and urine volume. Materials and Methods: The study included a total of 144 patients with (n=74) and without infection (n=70) out of 294 patients with AKI who received treatment between 1 January 2020 and 31 December 2021 in the nephrology clinic of a tertiary university hospital. Results: The mean age was 66.4±15.7 (range:19-95) in patients with infection and 63.8±15.2 (range:36- 93) in non-infected patients. 51.4% (n=38) of those with infection and 52.9% (n=37) of those without infection were women. There was no difference between the individuals with and without infection in terms of age and gender (p>0.05). Infection was present in 51.4% (n=74) of the patients included in the study. Urinary tract (31.3%) and respiratory tract infections (13.2%) were the most common in those with infection. A moderate negative correlation was observed between admission CRP and discharge creatinine level in patients with infection. There was no correlation between PCT and sedimentation rate, urine volume and admission/discharge creatinine level. Moderate positive correlations were found between admission/discharge PCT and admission/discharge urine volume in patients without infection. In addition, moderate negative correlations were found between admission/discharge sedimentation rate and admission urine volume. Conclusions: No correlation was found between PCT and sediment (incoming/exit) and outflow urine volume in patients with infection.
