COVID-19 in hemodialysis patients: a single-center experience in Istanbul.

Objective: Coronavirus disease 2019 (COVID-19) causes a wide spectrum of symptoms, from asymptomatic conditions to severe inflammatory response. Hemodialysis (HD) patients have a higher risk for developing severe COVID-19 because of older age, multiple co-morbid conditions, and impaired immune system compared to the general population. As little is known about these special groups, we evaluated the clinical characteristics and outcomes of HD patients with COVID-19.

Test of the recommended dialysis dose on one-year mortality of nondiabetic maintenance hemodialysis patients; observations from a single dialysis unit.

Background: The optimal delivered dialysis dose has been of a great interest for the last three decades, though a clear cut point has not been reached yet. We aimed to evaluate the relationship between one-year mortality and the delivered dialysis dose, which was recommended by Kidney Disease Outcomes Quality Initiative (KDOQI), in our maintenance hemodialysis (MHD) patients.

Methods: This was a single center, prospective observational study with one year of follow-up.

Is peritoneal dialysis a therapeutic option for polycystic kidney disease? 15 years' experience in a single center.

Background: Peritoneal dialysis (PD) is often avoided for patients with polycystic kidney disease (PKD) because of increased risk of complications and technique failure due to limited intra-abdominal space. In this study, we have aimed to determine clinical outcomes, patient and technique survivals in patients with PKD performing PD and to define whether PD is appropriate for these patients.

Methods: Totally 99 patients: 33 with PKD and 66 with diseases other than PKD were included in this retrospective study.

Comparison of Long-term Complications in Patients on Haemodialysis and Peritoneal Dialysis Longer than 10 Years.

Introduction: Depending on developments in dialysis techniques and new treatment strategies for comorbid diseases, life expectancy has increased. As a result, dialysis related long term complications could be seen more frequently. We investigated and compared long term complications of the Haemodialysis (HD) and Peritoneal Dialysis (PD) in patients with history if either mode at least 10years.

Familial Mediterranean Fever is associated with abnormal ventricular repolarization indices.

Background: Cardiac arrhythmias can be a part of cardiovascular involvement in some rheumatic diseases, but data about familial Mediterranean fever (FMF) are conflicting.

Aim: To search for abnormalities in ventricular repolarization indices in FMF patients.

Patients And Methods: Seventy seven FMF patients and 30 age/gender comparable healthy controls were included.

Clinical outcomes and mortality in elderly peritoneal dialysis patients.

Objectives: To evaluate the clinical outcomes and identify the predictors of mortality in elderly patients undergoing peritoneal dialysis.

Methods: We conducted a retrospective study including all incident peritoneal dialysis cases in patients ≥65 years of age treated from 2001 to 2014. Demographic and clinical data on the initiation of peritoneal dialysis and the clinical events during the study period were collected.

Relationship between relative interdialytic weight gain and serum leptin levels, nutrition, and inflammation in chronic hemodialysis patients.

Introduction: Excessive relative interdialytic weight gain (RIDWG, %) is an important risk factor for long-term adverse cardiovascular outcomes in chronic hemodialysis (HD) patients. On the other hand, it may also be an index of good appetite and nutritional status. We aimed to assess the relationship between RIDWG and appetite, nutrition, inflammation parameters of chronic HD patients.

Elevated serum leptin levels are associated with good nutritional status in non-obese chronic hemodialysis patients.

Objective: Leptin is a hormone and a proinflammatory cytokine secreted from adipocytes, which functions to suppress appetite in healthy persons. Serum leptin levels are significantly elevated in patients with end-stage renal disease (ESRD) primarily due to decreased clearance by the kidneys The consequence of hyperleptinemia in ESRD is not fully understood. We aimed to investigate the association between serum leptin levels and nutrition/inflammation status in non-obese chronic hemodialysis (HD) patients.

Outcome of 121 patients with renal amyloid a amyloidosis.

Background: Amyloid A (AA) amyloidosis is a multisystem, progressive and fatal disease. Renal involvement occurs early in the course of AA. We aimed to investigate the etiology, clinical and laboratory features, and outcome of patients with biopsy-proven renal AA amyloidosis.

Effects of AA amyloidosis on survival in peritoneal dialysis.

Background: To investigate the effects of ESRD etiologies on mortality in peritoneal dialysis patients.

Methods: We included patients who initiated therapy between 2001-2011 and classified them according to etiologies including amyloidosis, diabetes mellitus, chronic glomerulonephritis and polycistic renal disease. Socio-demographic data, clinical courses and infectious complications were compared between groups, and the reasons for peritoneal dialysis withdrawal were recorded.
