Introduction: ADPKD is the third most common disease-causing variant in autosomal dominant polycystic kidney disease (ADPKD) after ADPKD- and ADPKD-. This study aimed to characterize the clinical presentation, progression, and distinctive imaging phenotype of ADPKD-

Methods: This retrospective cohort study included patients with disease-causing variants in , nontruncating (), or . Patients were matched by sex (48.

In a subgroup of patients, coronavirus disease (COVID)-19 is a severe illness with high mortality due to hyperinflammation, development of acute respiratory distress syndrome, and multiorgan dysfunction syndrome. Complement system activation plays a critical role in the pathogenesis and severity of COVID-19 disease. This cross-sectional, single-center study aimed to investigate the correlation between serum C3 and C4 levels and COVID-19 severity.

Chronic kidney disease of unexplained cause (CKDx) is a diagnosis of exclusion. With an estimated global prevalence of at least 16-20% among CKD patients, CKDx poses a significant challenge to the field. To date, there is no established consensus on the definition of CKDx.

Rationale & Objective: Monoallelic predicted loss-of-function (pLoF) variants in IFT140 have recently been associated with an autosomal dominant polycystic kidney disease (ADPKD)-like phenotype. This study enhanced the characterization of this phenotype.

Study Design: Case series.

Background: Some of the hospitalized patients after severe COVID-19 pneumonia experience significant fall in peripheral saturation despite optimal treatment. Because of immune dysregulation in COVID-19 there are indications that prolonged corticosteroids could be considered in treating patients for persistent radiological sequelae and respiratory symptoms.

Objectives: to investigate lung function and lung sequelae on high-resolution CT (HRCT) im COVID-19 patients who were treated with glucocorticoid therapy in two dose regimens with a control group of patients who did not receive additional glucocorticoid therapy.

Article Synopsis
  • A retrospective study of 183 adult patients treated with rituximab for podocytopathies showed that 82% achieved complete or partial remission within 6 months.
  • *Long-term follow-up revealed that 55% of initial responders maintained relapse-free survival over three years, with improved outcomes linked to maintenance therapy.
  • *Patients on maintenance therapy experienced significantly fewer relapses per year and maintained stable kidney function compared to non-responders.

Article Synopsis
  • The study investigates the role of C4d deposits in patients with primary IgA nephropathy (pIgAN) and finds that C4d is present in 45.3% of patients, indicating activation of the lectin pathway of the complement system.* -
  • C4d-positive patients exhibited worse renal health outcomes, such as higher blood pressure, increased proteinuria, and lower eGFR, leading to faster progression to kidney failure.* -
  • The findings suggest that C4d can serve as an independent predictor of disease progression in pIgAN, but the implications for treatment using complement inhibitors remain unclear.*

Background: There are uncertainties regarding associations of prior proton pump inhibitor (PPI) use with susceptibility for COVID-19 and risks associated with SARS-CoV-2 infection. We aimed to evaluate the associations of prior PPI use with outcomes in hospitalized patients with COVID-19.

Research Design And Methods: We have retrospectively evaluated a total of 5959 consecutively hospitalized patients with COVID-19 from a tertiary-level institution in the period 3/2020-6/2021.

Collapsing glomerulopathy (CG) or collapsing focal segmental glomerulosclerosis (cFSGS) is an aggressive disease with a high tendency of progression to end-stage renal disease due to common resistance to conventional immunosuppressants. Rituximab (RTX), a monoclonal antibody against CD20 B cells, showed some benefit in the treatment of CG. We are reporting about female patients with an idiopathic form of CG presenting with nephrotic syndrome (NS) and renal insufficiency resistant to several immunosuppressive agents such as steroids (ST), calcineurin inhibitors (CNI), and cyclophosphamide (CYC).

Since the beginning of mass vaccination against coronavirus disease 2019 (COVID-19), vaccine-linked immune-mediated diseases have been increasingly reported. The development of these diseases after COVID-19 vaccination may be attributed to the mechanisms of molecular mimicry and cross-reactivity between the viral spike protein and self-antigens. The most frequent vaccine-linked glomerular disease is immunoglobulin A nephropathy (IgAN).

Aim: To assess the long-term survival after hospital discharge of patients hospitalized due to coronavirus disease 2019 (COVID-19).

Methods: We retrospectively reviewed data on post-discharge survival of 2586 COVID-19 patients hospitalized in our tertiary hospital from March 2020 to March 2021.

Results: Among 2586 patients, 1446 (55.

Objective: Our objective was to investigate the predictors of falls requiring a visit to the emergency department in patients with nonvalvular atrial fibrillation (AF) receiving different types of anticoagulants and to investigate the clinical consequences of falling in the same population.

Methods: A total of 1217 patients with nonvalvular AF from two institutions were retrospectively evaluated. Each patient underwent a physical examination, and clinical histories and medication profiles were taken from each patient at baseline.
