We studied liver biopsies performed between January 1972 and June 1980 in 111 patients receiving regular dialysis treatment. Biopsies were performed either because of suspected liver disease (61 patients) or routinely during abdominal surgery or kidney transplantation (50 patients). Repeat biopsies were done in 14 cases. Hepatitis B virus markers, assayed every 3 months during the observation period, were detected at some time in 71 patients (64%); 51 remained persistently positive. Histological examination showed normal liver in 39 cases, lobular hepatitis in 15, chronic persistent hepatitis in 36 and chronic active hepatitis in 21. All patients with chronic active hepatitis were chronic HBsAg carriers, and repeated biopsies showed aggravation only in these patients. The course was remarkably asymptomatic, with lesions leading to fibrosis despite the lack of histopathological patterns of severe necrosis and/or inflammation, which were conspicuously absent in this series.

Acute kidney injury and ANCA positivity in a patient treated with glecaprevir/pibrentasvir: a case report.
Front Med (Lausanne)
January 2025
Department of Pathology, Montefiore Medical Center, Bronx, NY, United States.
Background: Glecaprevir/pibrentasvir is an effective antiviral therapy for hepatitis C virus infection and is generally regarded safe in patients with renal impairment. However, renal complications are a notable, albeit rare, concern.
Case Presentation: We report a case of acute kidney injury in a man in his 50s with chronic hepatitis C virus, chronic obstructive pulmonary disease, morbid obesity, a history of heroin dependence, and untreated type 2 diabetes mellitus.
Differences in the intrahepatic expression of immune checkpoint molecules on T cells and natural killer cells in chronic HBV patients.
Front Immunol
January 2025
Univ. Grenoble Alpes, Inserm U 1209, CNRS UMR 5309, Institute for Advanced Biosciences, Grenoble, France.
Background: Patients with chronic hepatitis B virus (HBV) infection are characterized by impaired immune response that fails to eliminate HBV. Immune checkpoint molecules (ICMs) control the amplitude of the activation and function of immune cells, which makes them the key regulators of immune response.
Methods: We performed a multiparametric flow cytometry analysis of ICMs and determined their expression on intrahepatic lymphocyte subsets in untreated and treated patients with HBV in comparison with non-pathological liver tissue.
The Impact of Autosomal Dominant Polycystic Kidney Disease on the Presence of Cerebral Microbleeds: A Case-Control Matched Study.

Electronic address:
Rationale And Objectives: Individuals with autosomal dominant polycystic kidney disease (ADPKD) can present with diverse renal and extra-renal manifestations. Large vessel anomalies, such as cerebral aneurysms, are potentially fatal extra-renal manifestations. However, limited research has been conducted on cerebral small vessel disease (CSVD).

Methods: We used National Health and Nutrition Examination Surveys (NHANES 2017-2020) to estimate the prevalence of cirrhosis and clinically significant (CS)-portal hypertension in alcoholic liver disease (ALD), MetALD, viral hepatitis (VH) to include chronic hepatitis B (CHB) and chronic hepatitis C (CHC), and metabolic dysfunction-associated steatotic liver disease (MASLD). Cirrhosis was evaluated using liver stiffness measurement (LSM) by transient elastography or FIB-4 score; CS-portal hypertension was defined via LSM and platelet count or the use of non-selective beta-blockers in the presence of cirrhosis.
Identification of risk factors for suboptimal adherence in people living with HIV through measurement of medication possession ratio: a cross-sectional study.

Department of Knowledge Management, Sociedad Integral de Especialistas en Salud (SIES Salud IPS), Bogotá, Colombia.
The most significant progress in addressing the HIV/AIDS epidemic has been the development of antiretroviral therapy (ART). However, ensuring a high degree of treatment adherence is necessary to prevent resistance and disease progression. We conducted a cross-sectional study to evaluate adherence to ART through the calculation of the medication possession ratio (MPR) and to identify risk factors for suboptimal adherence in a cohort of HIV-positive patients receiving care at a Colombian healthcare institution across 16 cities.
