Epidemiological profile of kidney transplant patients with lupus nephritis.

Introduction: Lupus nephritis (LN) affects up to 50% of patients with systemic lupus erythematosus (SLE) and may lead to kidney failure and require kidney transplantation (KT). Results compared to KT from other causes are controversial, and we aimed to assess the clinical course, complications, and survival of LN patients undergoing KT.

Methodology: Retrospective cohort of 99 KT due to LN from 1977 to 2023 at a single center, divided into two groups according to the immunosuppression period: G1 (before 2009) and G2 (from 2009 onwards).

Kidney transplantation and perioperative complications: a prospective cohort study.

Background: Kidney transplant recipients face complex perioperative challenges due to comorbidities from chronic kidney disease. This study aimed to assess perioperative complications in kidney transplant recipients and evaluate the association between the Charlson Comorbidity Index (CCI) and complication severity using the Clavien-Dindo (CD) classification.

Methods: A prospective cohort study conducted at a tertiary hospital in South Brazil from September 2020 to March 2022, including 230 adult kidney transplant recipients.

Hypocitraturia as a biomarker of renal tubular acidosis in patients with Sjögren's disease.

Introduction: Sjögren's disease (SD) is an immune-mediated chronic inflammatory disease that affects epithelial tissues, mainly salivary and lacrimal glands. It also presents extraglandular manifestations. The main renal manifestation is tubulointerstitial nephritis (TIN), which can manifest as renal tubular acidosis (RTA).

Urinary Vacuolar Casts Are a Unique Type of Casts in Advanced Proteinuric Glomerulopathies.

Key Points: Vacuolar casts are a distinct type of casts identifiable by urinary sediment microscopy. Identification of urinary vacuolar casts is associated with the presence of an advanced and severe form of a proteinuric glomerular disease.

Background: Identification of casts by urinary sediment microscopy is a valuable diagnostic clinical tool for the evaluation of kidney disease.

Pregnancy after kidney transplantation: 40 years single-center experience.

Background: Kidney transplantation (KT) improves quality of life, including fertility recovery.

Objective: to describe outcomes of post-KT pregnancy and long-term patient and graft survival compared to a matched control group of female KT recipients who did not conceive.

Methods: retrospective single-center case-control study with female KT recipients from 1977 to 2016, followed-up until 2019.
