Background: In our study, diagnostic and demographic characteristics of patients diagnosed with minimal change disease (MCD) by biopsy, clinical and laboratory findings in our country were investigated.Methods: Data were obtained from the Turkish Society of Nephrology Glomerular Diseases (TSN-GOLD) Working Group database. Demographic characteristics, indications for biopsy, diagnosis of the glomerular diseases, comorbidities, laboratory and biopsy findings of all patients were recorded. The data presented is cross-sectional and includes application data for the biopsy period.Results: Of 3875 patients, 233 patients with MCD (median age 35.0 years) were included in the study, which constitutes 6.0% of the total glomerulonephritis database. Renal biopsy was performed in 196 (84.1%) patients due to nephrotic syndrome. Median serum creatinine was 0.7(0.6-1.0)mg/dl, mean eGFR was 104±33ml/min/1.73m2 and median proteinuria 6000 mg/day. The number of patients under the age of 40 years was 139 (59.7%) (Group A), and the number of patients aged 40 years and over was 94 (40.3%) (Group B). Compared to Group A, global sclerotic glomeruli (24 vs. 43,pConclusion: Our data are generally compatible with the literature. Chronic histopathological changes were more common in patients aged 40 years and older than younger patients. Studies investigating the effects of these different features on renal survival are needed.

Living with end-stage renal disease may be burdensome, not only for patients, but also for caregivers. In this study, we aim to compare caregiver burden, psychological symptoms in caregivers of peritoneal dialysis (PD), hemodialysis (HD), and transplantation (TX), and find out associated factors. A total of 43 PD, 42 HD, 42 TX patients and a total of 127 caregivers that were actively involved with the care of their patients’ dialysis were enrolled. Patients had been on renal replacement therapy at least for 6 months and caregivers had given care at least for 6 months. The World Health Organization Quality of Life short version and hospital anxiety and depression scale (HAD) were applied to the patients. Symptom Checklist-90-Revised and Zarit caregiver burden scale were applied to the caregivers. Zarit caregiver burden score was found highest in HD group, which was significantly higher than PD and TX. All three groups had similar HAD anxiety scores, whereas the HAD depression score was highest in HD group, lower in PD, and lowest in TX. Quality of life was lowest in HD group. Zarit caregiver burden score was found higher in caregivers with symptoms like somatization, anxiety, obsessive–compulsive, depression, interpersonal sensitivity, psychoticism, paranoid ideation, hostility, and additional psychological symptoms than the ones who did not have these symptoms. Psychological symptoms were similar in PD, HD, and TX groups. Caregiver burden was found highest in HD group. Educational, social, and psychological support interventions may be considered for caregivers.

PubMed ID: 30251011 Purpose: Renal infarction is a clinical condition which is caused by renal artery occlusion and leads to permanent renal parenchymal damage. In the literature, there are generally case reports on this subject, and few studies that include a large group of patients. Therefore, we aimed to present the data of a large group of patients who were diagnosed with acute renal infarction in our country in this retrospective study. Methods: The data of patients who were diagnosed with acute renal infarction according to clinical and radiological findings in Turkey in the last 3 years were examined. For this purpose, we contacted with more than 40 centers in 7 regions and obtained support from clinically responsible persons. Demographic data of patients, laboratory data at the time of diagnosis, tests performed for etiologic evaluation, given medications, and patients’ clinical status during follow-up were obtained from databases and statistical analysis was performed. Results: One-hundred and twenty-one patients were included in the study. The mean age was 53 ± 1.4 (19–91) years. Seventy-one (58.7%) patients were male, 18 (14.9%) had diabetes, 53 (43.8%) had hypertension, 36 (30%) had atrial fibrillation (AF), and 6 had a history of lupus + antiphospholipid syndrome (APS). Forty-five patients had right renal infarction, 50 patients had left renal infarction, and 26 (21.5%) patients had bilateral renal infarction. The examinations for the ethiologies revealed that, 36 patients had thromboemboli due to atrial fibrillation, 10 patients had genetic anomalies leading to thrombosis, 9 patients had trauma, 6 patients had lupus + APS, 2 patients had hematologic diseases, and 1 patient had a substance abuse problem. Fifty-seven (57%) patients had unknown. The mean follow-up period was 14 ± 2 months. The mean creatinine and glomerular filtration rate (GFR) values at 3 months were found to be 1.65 ± 0.16 mg/dl and 62 ± 3 ml/min, respectively. The final mean creatinine and GFR values were found to be 1.69 ± 0.16 mg/dl and 62 ± 3 ml/min, respectively. Conclusions: Our study is the second largest series published on renal infarction in the literature. More detailed studies are needed to determine the etiological causes of acute renal infarction occurring in patients. © 2018, Springer Nature B.V.

Electrolyte imbalance is a common problem affecting the elderly. Increased number of comorbidities and frequent use of drugs may contribute to increased risk of hypokalemia in the elderly. This study was performed to investigate the prevalence of community-acquired hypokalemia (CAH), risk factors for its development, related factors with hypokalemia, and morbidities and all-cause mortality rates (MR) of CAH in the elderly patients. Total of 36,361 patients aged above 65 years were screened retrospectively. Group 1 consisted of 269 elderly patients with potassium level ≤3.5 mmol/L, and group 2 (control group) consisted of 182 subjects with potassium level between 3.6 and 5.5 mmol/L. Etiologic factors of CAH, presence of comorbidities, duration of hospital stay, hospital cost, and clinical outcomes were recorded. Prevalence of hypokalemia was found 3.24% in patients aged above 65 years. Duration of hospital stay, presence of ≥2 comorbid diseases, hospital cost, and MR were significantly higher in group 1 compared to group 2 (p
