Cystic phenotype and chronic kidney disease in autosomal dominant Alport syndrome.

Background: Autosomal dominant Alport Syndrome (ADAS), also known as thin basement membrane disease (TBMD), is caused by pathogenic variants in the COL4A3 and COL4A4 genes. A cystic phenotype has been described in some patients with TBMD, but no genetic studies have been performed. We conducted a genetic and radiologic investigation in a cohort of ADAS patients to analyze the prevalence of multicystic kidney disease (MKD) and its association with chronic kidney disease (CKD).

Humoral Response Following Triple Dose of mRNA Vaccines Against SARS-CoV-2 in Hemodialysis Patients: Results After 1 Year of Follow-Up.

Introduction: COVID-19 is associated with an increased mortality in hemodialysis patients. Therefore, achieving a long-lasting effective immune response to SARS-CoV-2 vaccines is essential. This study describes the humoral immune response in hemodialysis patients following three doses of mRNA vaccines against SARS-CoV-2, and explores the factors associated with a sustained immune response.

Vitamin K antagonist-associated microscopic hematuria.

Background: Vitamin K antagonists (VKA) are the most widely used anticoagulants for the prevention of thrombotic events. Several renal adverse effects have been associated with the use of VKA. The main aim of our study was to explore the association between international normalized ratio (INR) levels and microscopic hematuria in patients with VKA.

Facing the Challenge of Drug-Induced Acute Interstitial Nephritis.

Background: Acute interstitial nephritis (AIN) is one of the chief causes of acute kidney injury (AKI). AIN might be produced by drugs, infections, autoimmune diseases, or can be idiopathic. Among these etiologies, drug-induced AIN (DI-AIN) is the dominant one in many countries.

Serum interleukin-6 levels predict kidney disease progression in diabetic nephropathy.

Background: Inflammation is a main mechanism for the pathogenesis and progression of diabetic kidney disease (DKD). Interleukin-6 (IL-6) is an important inflammatory mediator that is suggested to be involved in the pathogenesis of DKD. The aim of our study was to evaluate the association between IL-6 levels and progression of DKD in patients with type 2 diabetes mellitus.

The Role of Vascular Lesions in Diabetes Across a Spectrum of Clinical Kidney Disease.

Introduction: The clinical-histologic correlation in diabetic nephropathy is not completely known.

Methods: We analyzed nephrectomy specimens from 90 patients with diabetes and diverse degrees of proteinuria and glomerular filtration rate (GFR).

Results: Thirty-six (40%) subjects had normoalbuminuria, 33 (37%) microalbuminuria, and 21 (23%) non-nephrotic proteinuria.

Urinary Dickkopf-3: a new biomarker for CKD progression and mortality.

Background: Kidney fibrosis has been reported to be a prognostic factor in chronic kidney disease (CKD) progression. Previous studies have shown that the assessment of urinary Dickkopf-3 (uDKK3), a stress-induced tubular epithelial-derived profibrotic glycoprotein, might be a potential tubulointerstitial fibrosis biomarker and might identify patients at short-term risk of glomerular filtration rate loss. We aim to evaluate uDKK3 as a potential biomarker for progression of CKD in a cohort with various aetiologies of CKD and subsequently in an overt diabetic nephropathy cohort.

Late thrombotic complications after SARS-CoV-2 infection in hemodialysis patients.

Introduction: There is an increased risk of thrombotic complications in patients with COVID-19. Hemodialysis patients are already at an increased risk for thromboembolic events such as stroke and pulmonary embolism. The aim of our study was to determine the incidence of late thrombotic complications (deep vein thrombosis, pulmonary embolism, stroke, new-onset vascular access thrombosis) in maintenance hemodialysis patients after recovery from COVID-19.

Therapeutic Insights in Chronic Kidney Disease Progression.

Chronic kidney disease (CKD) has been recognized as a leading public health problem worldwide. Through its effect on cardiovascular risk and end-stage kidney disease, CKD directly affects the global burden of morbidity and mortality. Classical optimal management of CKD includes blood pressure control, treatment of albuminuria with angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers, avoidance of potential nephrotoxins and obesity, drug dosing adjustments, and cardiovascular risk reduction.

Direct-acting antiviral therapy improves kidney survival in hepatitis C virus-associated cryoglobulinaemia: the RENALCRYOGLOBULINEMIC study.

Background: Direct-acting antiviral agents (DAAs) have shown high rates of sustained virological response in chronic hepatitis C virus (HCV) infection. However, the influence of DAAs on the course of kidney involvement in HCV-associated mixed cryoglobulinaemia (HCV-MC) has been little studied. The aim of this study was to analyse the effects of antiviral treatment on kidney prognosis and evolution in patients diagnosed with HCV-MC.

Fulminant Emphysematous Pyelonephritis by Candida glabrata in a Kidney Allograft.

Emphysematous pyelonephritis (EPN) is a rare and serious necrotizing infection that is potentially life-threatening. It has been seldom reported in kidney grafts and is usually caused by Gram-negative bacteria, with some case reports caused by anaerobic bacteria, and has been closely associated with poorly controlled diabetes mellitus (DM) and urinary tract structural abnormalities. There are no reports of EPN of fungal etiology in kidney grafts.
