COVID-19 in Kidney Transplant Recipients: A Multicenter Experience from the First Two Waves of Pandemic.

Background: Kidney transplant recipients have an increased risk of complications from COVID-19. However, data on the risk of allograft damage or death in kidney transplant recipients recovering from COVID-19 is limited. In addition, the first and second waves of the pandemic occurred at different times all over the world.

The Effect of Alendronate on Bone Mineral Disorder in Renal Transplant Patients.

Purpose: In this study, we aimed to investigate the effect of long-term administration of alendronate to treat bone loss in renal transplant patients.

Methods: Eighty-two renal transplant recipients were divided into 3 groups. Group 1 included patients who were treated with calcium, vitamin D3, and alendronate; group 2 included patients who were treated with calcium and vitamin D3; and group 3 included patients who did not receive these medications.

Unexpectedly High Prevalence of Low Alpha-Galactosidase A Enzyme Activity in Patients with Focal Segmental Glomerulosclerosis.

Objectives: Fabry disease (FD) is a rare disease associated with sphingolipid accumulation. Sphingolipids are components of plasma membranes that are important in podocyte function and accumulate in various glomerular diseases such as focal segmental glomerulosclerosis (FSGS). Both FD and FSGS can cause podocyte damage and are classified as podocytopathies.

Clinical Prognosis of Renal Retransplant Patients: A Single-Center Experience.

Background: Retransplantation is a treatment option in patients with end-stage renal failure due to graft loss. Outcomes of these patients due to high immunologic risk remain unclear. The aim of this study was to evaluate outcomes of renal retransplantation patients retrospectively.

Incisional Complications and Cosmetic Evaluation After Hand-assisted Retroperitoneoscopic Donor Nephrectomy.

Purpose: Hand-assisted retroperitoneoscopic (HARP) donor nephrectomy prevents major complications, but incision site complications may be more frequent in hand-assisted approach. We evaluated long-term incisional complication rates and cosmetic outcomes after HARP donor nephrectomy in our series.

Materials And Methods: A total of 609 donors who underwent nephrectomy between February 2009 and June 2016 were invited for physical examination and face-to-face interview.

Hand-Assisted Nephrectomy Predisposes Incisional Herniation in Obese Living Donors.

Background: Living kidney donation from donors with a body mass index (BMI) over 30 can bring risks for the donor and the recipients. In this retrospective study, we evaluated the effect of a donor's obesity on a donor's long-term surveillance and the recipient outcomes.

Method: We performed hand-assisted retroperitoneoscopic donor nephrectomy in 565 living kidney transplantations between February 2009 and December 2015.

Outcome of Desensitization Therapy in Immunologically High-Risk Kidney Transplantation: Single-Center Experience.

Aim: Sensitization to HLA antigens creates an immunologic barrier, linked to an increased risk of antibody-mediated rejection and poorer graft survival, that remains a persistent and often impenetrable deterrent to transplantation. Desensitization can improve transplantation rates in broadly sensitized kidney transplant recipients. We aimed to compare the clinical outcomes of immunologic high-risk kidney recipients who had desensitization treatment with the outcomes of those who did not.

Encapsulated peritoneal sclerosis: a single center, retrospective analysis of clinical manifestations, risk factors and prognosis.

Background: Encapsulated peritoneal sclerosis (EPS) is a multifactorial chronic intra-abdominal inflammatory disorder affecting the peritoneum diffusely. The aim of this study was to evaluate the rates of EPS in our peritoneal dialysis (PD) population, to perform a general assessment of the clinical presentation and to determine the outcome of affected patients and risk factors.

Methods: The medical records of consecutive 384 patients who started PD therapy between January 2001 and November 2016 were evaluated.

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.

The relationship between serum albumin levels and 24-h ambulatory blood pressure monitoring recordings in non-diabetic essential hypertensive patients.

Objectives: The goal of this study was to evaluate the relationship between serum albumin levels and 24-hour ambulatory blood pressure monitoring (24-h ABPM) recordings in non-diabetic essential hypertensive patients.

Methods: A total of 354 patients (mean [SD] age: 55.5 [14.

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.

Persistent left superior vena cava: Two case reports and a review from nephrologists' perspective.

Thoracic venous anomalies without congenital heart anomalies are present in minority of the population, but they are frequent enough to be encountered while placing hemodialysis catheters through the jugular or subclavian veins. Persistent left superior vena cava is the most commonly seen anomaly and it is rarely noticed before the observation of an unusual course of hemodialysis catheter or guidewire on chest X-ray. We present two patients with previously unspotted persistent left superior vena cava and uncomplicated hemodialysis catheter insertions through the internal jugular veins with good catheter functions.

Neutrophil-to-lymphocyte ratio and platelet-tolymphocyte ratio in evaluation of inflammation in end-stage renal disease.

Objective: To evaluate the relationship between neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and inflammation in end-stage renal disease (ESRD) patients on maintenance hemodialysis (HD).

Methods: 100 ESRD patients on maintenance HD (mean ± SD age: 52.3 ± 1.

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.
