Occupational Heat Exposure as a Risk Factor for End-Stage Kidney Disease: A Case-Control Study.

Objective: More patients are reaching end-stage kidney disease without evident cause. This study aims to explore occupational risk factors associated with hemodialysis.

Methods: A multicenter matched case-control study included dialysis patients and age, sex, and diabetes-matched controls (normal kidney function).

Age and multimorbidities as poor prognostic factors for COVID-19 in hemodialysis: a Lebanese national study.

Background: Hemodialysis patients with COVID-19 have been reported to be at higher risk for death than the general population. Several prognostic factors have been identified in the studies from Asian, European or American countries. This is the first national Lebanese study assessing the factors associated with SARS-CoV-2 mortality in hemodialysis patients.

Etiology of End-Stage Renal Disease and Arterial Stiffness among Hemodialysis Patients.

. Prior studies have demonstrated that conventional and emerging CV risk factors are associated with worsening arterial stiffness among end-stage renal disease (ESRD) patients on hemodialysis. The present cross-sectional study evaluates the association between the etiology of ESRD and arterial stiffness among a cohort of hemodialysis patients.

Change in Pulse Wave Velocity and Short-Term Development of Cardiovascular Events in the Hemodialysis Population.

The association between single measurements of carotid-femoral pulse wave velocity (cfPWV) and cardiovascular (CV) events is driven by late events beyond 12 months of follow-up. This prospective study compares single measurements of cfPWV vs the 2-year delta cfPWV and the association with short-term development of CV events in hemodialysis patients. cfPWV was performed at t=0 and t=1 two years later, and patients were followed-up for development of CV events through 12 months (n=66).

Nonprogressive kidney dysfunction and outcomes in older adults with chronic kidney disease.

Objectives: To determine whether a subgroup of patients with severe but nonprogressive renal dysfunction exist and to characterize this subgroup.

Design: Retrospective longitudinal monocentric cohort study.

Setting: Nephrology clinic for chronic kidney disease (CKD).

Urinary procollagen III aminoterminal propeptide (PIIINP): a fibrotest for the nephrologist.

Background And Objectives: Kidney biopsy (KB), to date the only tool for the evaluation of renal fibrosis, carries specific risks, and its relevance is limited by the small size of renal parenchyma assessed. Thus, a noninvasive alternative to KB is required. Collagen type III amino-terminal propeptide (PIIINP) is a degradation product of collagen type III, the increase of which may reflect an ongoing fibrotic process.

Pauci-immune crescentic glomerulonephritis associated with ANCA of IgA class.

Pauci-immune renal vasculitis is associated strongly with antineutrophil cytoplasmic antibodies (ANCAs) of the immunoglobulin G (IgG) class, which are detected in 80% to 90% of affected patients. IgA ANCAs have been reported in association with various conditions, but never in the setting of pauci-immune vasculitis. A 28-year-old man with unexplained polyclonal hyper-IgA1 diagnosed in childhood presented with decreased kidney function, nephrotic syndrome, and microscopic hematuria.

Cyclosporine lymphocyte maximum level: a new alternative for cyclosporine monitoring in kidney transplantation.

Objectives: To determine the relationship between clinical outcome, lymphocyte count (LC), and cyclosporine (CsA) lymphocyte maximum level (LT(m)L) in kidney transplant recipients.

Materials And Methods: CsA LT(m)L was determined in patients with biopsy-proven graft dysfunction and in patients with normal graft function. Clinical outcome was compared according to CsA LT(m)L, dosage, blood trough (C(0)) and maximum (C(max)) levels, hematocrit level, and LC.
