Association of signal transducer and activator of transcription, interleukin-6, and interleukin-10 positivity with antiviral treatment in cirrhotic liver samples from patients with the hepatitis B or C virus

Abstract

Objective: Terminal liver disease due to viral hepatitis infections is an important health problem. This study aimed to compare the expression of members of the signal transducer and activator of transcription (STAT) family (STAT-1, -2, -3, -5a, and -5b) and interleukin (IL)-6 and IL-10 in hepatectomy material from patients who received antiviral treatment and underwent a liver transplantation due to terminal liver failure. Methods: The study consisted of 45 patients who underwent a liver transplantation due to chronic liver failure associated with viral hepatitis (hepatitis C virus [HCV] or hepatitis B virus [HBV]). The patients were divided into three groups according to the drug treatments they received prior to the liver transplantation: Group A: lamivudine, Group B: adefovir, and Group C: interferon or interferon + ribavirin. Results: In the study population, 9 (20%) patients were females and 36 (80%) were males. The mean age was 45.7 (29–69) years. STAT-2, -3, and IL-6 expression were significantly higher in hepatocytes in Group A (p<0.05). Conclusion: High STAT-3, high IL-6, and low STAT-1 expression were associated with optimum hepatocyte regeneration and liver metabolic function. In this regard, lamivudine was the most effective drug in the present study.

Objectives: Hidradenitis suppurativa is seen as a result of the occlusion, constriction and bacterial infection of the apocrine glands in bilateral axillas, submammarian areas, neck, inguinal regions, flexural surfaces of the thighs and anogenital areas. Among the biological agents adalimumab is a recombinant human IgG1 monoclonal antibody; TNF-α antagonist approved to be used in the treatment of hidradenitissuppurativa. Methods: In this study, 12 patients resistant to conventional treatments with moderate severity, Hurley stage 2 or 3 were started subcutaneous adalimumab treatment. The disease activities upon the hidradenitis suppurativa, clinical severity index and life quality index of the patients were examined both before and 1 year after the treatment. Results: Twelve patients were recruited. In the examination of the hidradenitis suppurativa clinical severity scores, significant clinical responses were noted in 9 (75%) patients. While the mean value of the life quality index was 14.4±6.9 before the treatment, it was determined to be significantly decreased to 4.3±3.8 after the treatment. Conclusion: We concluded that adalimumab; the unique biological agent approved to be used in the treatment of treatment-resistant, moderate-severe hidradenitis suppurativa is efficient and safe in similar ratios with the previous clinical studies in the literature.
