With the introduction of more efficient treatments for hepatitis C virus (HCV), improved epidemiological information is required at the country level to allow evidence-based policymaking for elaboration of national strategies and HCV resources planning. We present a systematic review with meta-analysis of HCV seroprevalence data in adults in African countries. We conducted a systematic review of all HCV seroprevalence estimates reported in African countries from 2000 to 2014 in MEDLINE, AJOL and grey literature. We assessed studies performed in the general population and among blood donors, pregnant women and HIV-positive patients. A meta-regression analysis was used to provide adjusted estimates of HCV seroprevalence in the general adult population in each country, accounting for the heterogeneity in sample age structure and population types in the included studies. We identified 775 national-level estimations, among which 184 were included. Estimates of HCV seroprevalence were produced for 38 countries, in addition to the results from nationwide representative surveys available in Egypt and Libya. Next to Egypt, which clearly stands out, the highest levels of seroprevalence were found in Middle Africa (e.g. Cameroon, Gabon and Angola) and some West African countries (e.g. Burkina Faso, Benin), and the largest absolute numbers of infected adults were found in Nigeria, Ethiopia and Democratic Republic of Congo. This study exposes the diversity of HCV epidemiology among African countries. Egypt and several countries of West and Middle Africa present a HCV burden that will require strong governmental commitment to promote efficient preventive and curative interventions.

Background: Chronic infection with HCV is a progressive worldwide health problem and the core reason for liver cirrhosis, portal hypertension, or hepatocellular carcinoma. HCV-G4 represents the most common threat for transplantation of the liver in Egypt. New interferon-free regimens have been started consuming direct-acting antiviral oral tablets for HCV cure. Objectives: In the current study, comparing the safety and efficacy of DAAs combination regimens including sofosbuvir with daclatasvir or sofosbuvir with simeprevir plus ribavirin for naïve cirrhotic Egyptian patients infected with HCV-G4 was our main goal. Methods: We recruited 150 naïve cirrhotic HCV patients from the Tropical patients’ clinic at Fayoum General Hospital. They were classified randomly into two groups, group one (n=75 patients) were administrated Sofosbuvir plus simeprevir (400 mg and 150 mg once daily respectively ) for twelve weeks, group two (n=75 patients) were administrated Sofosbuvir plus Daclatasvir (400 mg and 60 mg once daily respectively) with ribavirin (1-1.2gm daily weight-based) for twelve weeks. Clinical follow-up, laboratory investigations, and viral PCR were measured for detecting treatment efficacy, safety, and any adverse events. Results: Sustained virological response rates (SVR12) were 92%and 90.7% in the first and second groups, respectively. The major unfavorable events were fatigue, arthralgia, and weight loss without statistically meaningful differences between study groups. However, anemia and headache were significantly widespread in the second group (P=0.0161 and 0.0495, respectively). We observed four patients with photosensitivity in group I and not observed in the second group. Conclusions: The current study revealed that DAAs are safe and effective in the cure of naïve cirrhotic patients chronically infected by HCV-G4 with better results in those treated with sofosbuvir plus simeprevir regimen.
