A study was made of the immune status in patients suffering from chronic hepatitis (CH) of viral, alcoholic and toxic etiology. The T-system cellular immunity (OKT-3+, OKT-4+, OKT-8+, OKT-11+) was subjected to a subpopulation analysis using monoclonal antibodies and flow laser cytometry. CH of varying etiology is marked by impairment of the immune status. Especially manifest are suppression of OKT-3(+)-, OKT-4(+)-, OKT-8(+)-positive cells and imbalance of OKT-4+ and OKT-8+, with the changes revealed being dependent on the etiological pattern of CH. The data obtained point to the development of secondary immunodeficiency of the T-cell component at the level of different T lymphocyte subpopulations, which depends on the clinico-morphological and etiological pattern of CH. The revealed changes in the immune system may serve as a criterion for differential diagnosis and elaboration of efficient immunocorrective therapy of CH.

Hepatitis B virus (HBV) X protein (HBx) is a key factor for regulating viral transcription and replication. We recently characterized homeobox protein MSX-1 (MSX1) as a host restriction factor that inhibits HBV gene expression and genome replication by directly binding to HBV enhancer II/core promoter (EnII/Cp) and suppressing its promoter and enhancer activities. Notably, HBx expression was observed to be repressed more drastically by MSX1 compared to other viral antigens.

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.

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.

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.
