    A Decade of Hepatitis C at the UCT/GSH Liver Clinic in the Pre-DAA era
    (2019) Nordien, Rozeena; Sonderup, Mark; Spearman, Wendy
    Background Hepatitis C (HCV) in South Africa is incompletely characterised and understood. Epidemiological and clinical data will better inform our understanding and assist national policy decision making. On the background of more than two decades of clinical challenges in HCV management, the advent of direct acting antivirals (DAA) now makes HCV elimination plausible. To better understand the base from which we come, we elected to review and characterise our HCV experience at Groote Schuur Hospital (GSH) in the Pegylated interferon (Peg-IFN) and Ribavirin (RBV) management era. Methods Patients with chronic HCV attending GSH Liver Clinic from 2002 to 2014, were included, in the analysis. Relevant data were extracted from a registry and existing clinical records accessed. Two brands of Peg-IFN were available and those treated with the first generation add-on protease inhibitor, telaprevir, were included. Results 238 patients were included in the analysis, median age of 47 (IQR 37-58) years, men 60.5%. Men were significantly younger than women, 43.5 (35-52) vs 55 (42-64) years, respectively, p< 0.0001. Ethnically, the majority were white (55.9%) or mixed-ancestry (21.8%), 16.4% were HIV co-infected, 3.7% hepatitis B (HBV) co-infected and 0.4% triple infected with HCV, HBV and HIV. The most likely mode of HCV acquisition was blood/blood product exposure prior to 1992 (32.8%) and injecting drug use (IDU) 17.6%, while 30.3%, had no clear risk factor identifiable. Genotypes (GT) 1 to 5 were observed with GT-1 (34.9%) predominating. In those biopsied, (n=90), 30% ≥F3 fibrosis, with 15.6% cirrhotic. With IL28B polymorphisms, heterozygous CT (23.9%) and CC genotype (15.5%), were most frequent. 32.6% accessed Peg-IFN/Ribavirin-based therapy, 6.5% (n=5) with add-on telaprevir. GT-1 (35.1%) was most prevalent in the treatment group, followed by GT-3 (26%) and GT-5 (18.2%); 10% were HIV co-infected. Overall SVR rate was 75.3% with 37% of GT-1 not achieving SVR; 49.4% experienced adverse events including cytopaenias (32.5%) and depression (15.6%) with 15.6% requiring erythropoietin for anaemia and 15.6% GM-CSF for neutropaenia. Conclusion HCV patients in the Peg-IFN/Ribavirin management era typified the epidemiology of HCV. GT distribution was pangenotypic and treatment outcomes were encouraging despite treatment challenges. Patient selection, IL28B and sensible cytopaenia support, likely accounted for this. However numbers treated were limited and the DAA era of therapy allows for a rapid expansion of therapy with now growing numbers of patients and a changing local epidemiology.
