ANCA-associated vasculitis after COVID-19.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) are systemic autoimmune diseases that may lead to renal failure due to the infiltration of mononuclear cells and the destruction of small- and medium-sized blood vessels. It has been shown that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may trigger the presentation or exacerbation of autoimmune diseases. Crescentic glomerulonephritis (GN) has rarely been reported in patients with Coronavirus disease-2019 (COVID-19).

Emerging biomarker for predicting acute kidney injury after cardiac surgery: cystatin C.

Background/aim: Cardiopulmonary bypass (CPB)-associated acute kidney injury (AKI) is a common situation and rapid diagnosis and risk classification are important in the prevention and management of AKI. Changes in serum creatinine (SCr) levels in the current consensus criteria do not allow clinicians to diagnose CPB-associated AKI until 48 h after surgery.

Materials And Methods: We conducted a prospective single center study involving 57 patients who underwent cardiac surgery with CBP to compare serum beta-trace protein (BTP), neutrophil gelatinase-associated lipocalin-2 (NGAL), and cystatin C (CysC) levels with SCr for early diagnosis of CPB associated AKI.

Acute renal infarction in Turkey: a review of 121 cases.

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.

Angiotensin Converting Enzyme Gene Insertion/Deletion Variant and Familial Mediterranean Fever-related Amyloidosis.

Introduction: The most important complication of familial Mediterranean fever (FMF) is secondary amyloidosis, which can lead to kidney failure. Genetic variability in the genes of various components of the renin-angiotensin system may play a role in the pathogenesis of the kidney disorders.  The aim of the present study was to investigate the association between angiotensin converting enzyme (ACE) gene I/D variant and risk of developing FMF-related amyloidosis in Turkish patients.

HFE gene mutation is a risk factor for tissue iron accumulation in hemodialysis patients.

Introduction: HFE gene mutations are responsible from iron overload in general population. Studies in hemodialysis patients investigated the effect of presence of HFE gene mutations on serum ferritin and transferrin saturation (TSAT) with conflicting results. However effect of HFE mutations on iron overload in hemodialysis patients was not previously extensively studied.

Mutational Spectrum of the MEFV Gene in AA Amyloidosis Associated With Familial Mediterranean Fever.

Introduction: Familial Mediterranean fever (FMF) is a recessively inherited disease which is characterized by recurrent episodic fever, abdominal pain, and polyserositis. It is caused by mutations in the MEFV gene, encoding the pyrin protein. The most important complication of FMF is secondary (AA) amyloidosis that leads to kidney failure.

Kidney transplantation for end-stage renal disease secondary to familial Mediterranean fever.

Although kidney transplantation (KT) is widely used for treating renal amyloidosis secondary to familial Mediterranean fever (FMF), data concerning transplant outcome are limited and inconsistent. The aim of this study was to determine the long-term outcome of KT in patients with amyloidosis secondary to FMF. Kidney transplantation outcome in 24 patients with FMF was compared to that in 72 controls matched for age, gender of recipient, and type of the donor that underwent KT due to end-stage renal disease (ESRD) not caused by FMF.

Safety of Percutaneous Ultrasound-Guided Kidney Biopsy in Patients with AA Amyloidosis.

Background: Bleeding is the most frequent complication of kidney biopsy. Although bleeding risk in patients with AA amyloidosis after kidney biopsy has not been studied in a large population, AA amyloidosis has long been perceived as a risk factor for bleeding. The aim of the present study was to evaluate post-biopsy bleeding risk in patients with AA amyloidosis.

Tip lesion variant of primary focal and segmental glomerulosclerosis: clinicopathological analysis of 20 cases.

The glomerular tip lesion (GTL) is a distinctive histopathologic lesion which is regarded as a variant of focal and segmental glomerulosclerosis (FSGS). The prognostic significance of GTL among other FSGS variants has been disputed. In order to define the clinical features and outcome of GTL, we retrospectively reviewed the presenting clinical features, laboratory and biopsy findings and surveillance in our cohort of GTL, which consisted of 20 adults with native kidneys (mean age 46 years) with follow-up data ranging from 3 to 137 months.

Blood pressure measurements, blood pressure variability and endothelial function in renal transplant recipients.

Background/aims: Hypertension is an important cardiovascular risk factor in renal transplant recipients. Elevated blood pressure variability (BPV) during 24-h ambulatory blood pressure monitoring (ABPM) is associated with increased risk of target organ damage and cardiovascular events, independent of mean blood pressure levels. We aimed to evaluate the relationship between endothelial function, blood pressure levels obtained by various measurement methods, and BPV in renal transplant recipients.

Congenital megacalycosis with IgA nephropathy: a case report and review of the literature.

Congenital megacalycosis is a rare renal disease characterized by calyceal dilatation without pelvic or ureteral obstruction. If not accompanied by nephrolithiasis and urinary tract infection, this disease is completely benign and does not cause renal dysfunction. We present a case of congenital megacalycosis that was diagnosed at the age of 41 (oldest case in the literature) after admitting with hematuria and acute renal dysfunction.

Relationship between hemorheology and endothelial dysfunction in renal transplant patients receiving calcineurin inhibitors.

Background: Calcineurin inhibitors, mainly cyclosporin A (CsA), are associated with endothelial dysfunction in renal transplant recipients (RTRs). Hemorheological disturbances including decreased erythrocyte deformability (ED), increased plasma viscosity and erythrocyte aggregation (EA) have also been reported in CsA-treated RTRs. The aim of this study was to investigate the relationship between hemorheological factors and endothelial dysfunction in CsA- and tacrolimus (Tc)-treated RTRs.
