Objectives: To find out the frequency and etiology of lymphadenopathy at various sites distant from perihepatic region during combination therapy (pegylated interferon Alpha Plus Ribavirin) for chronic hepatitis C.
Methods: Retrospective case-control study conducted at Medical unit I of Liaquat University Hospital Jamshoro, Sind, Pakistan. The charts of 205 patients undergoing antiviral therapy with pegylated interferon alpha plus ribavirin for chronic hepatitis C at our ward from May 2009 to April 2010, were reviewed for those who developed lymphadenopathy at sites distant from perihepatic region.
Results: Out of 205 patients, 130 (63.41%) were males. Mean age of males was 37.11 +/- 9.81 years and of females 42.31 +/- 8.79 years. In total, 20 (9.75%) patients in control or 10/95 (10.52%) patients treated within clinical trials, were recorded to have lymphadenopathy during combination antiviral therapy for chronic hepatitis C. The most common site of lymphadenopathy was inguinal region in 08 (40%), followed by cervical region in 07 (35%) patients. Majority 16 (80%) of patients having lymphadenopathy were infected with HCV genotype 3a, and 17 (85%) have achieved sustained virological response. The etiology of lymphadenopathy was reactive in most 15 (75%) of our patients, followed by tuberculosis in 03 (15%). The average time for onset of lymphadenopathy during antiviral therapy for chronic hepatitis C was 21 weeks.
Conclusion: In conclusion, lymphadenopathy at various sites distant from perihepatic region appears to be higher than that documented in previous studies. In majority of our patients, the lymphadenopathy was reactive and resolved upon cessation of antiviral therapy.

Background: Human hepatitis is an inflammation of the liver brought on by the DNA virus known as the hepatitis B virus (HBV). Around the world, 240 million people are thought to have HBV in a chronic state. The prevalence of viral hepatitis is extremely high in Africa.

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.
