- Abstract: Objectives: Highly effective direct‐acting antivirals (DAAs) for Hepatitis C treatment are largely inaccessible in sub‐Saharan Africa. Data on treatment feasibility and outcomes in clinical settings are limited. We assessed the feasibility of achieving a high (≥90%) cure rate with DAAs in six gastroenterology clinics in Cameroon. Methods: Patients with chronic Hepatitis C virus (HCV) infection were treated for 12 or 24 weeks with ledipasvir/sofosbuvir, ledipasvir/sofosbuvir/ribavirin or sofosbuvir/ribavirin, depending on the stage of liver disease and HCV genotype. The cure rate was defined as the proportion of patients with a sustained virological response 12 weeks after treatment completion (SVR12) among all treatment completers. Results: We identified 190 HCV RNA positive patients between September‐2017 and August‐2018, 161 (84.7%) of whom started treatment. 105 (65.2%) were female, median age was 61.3 years [IQR = 55.9–66.9] and 11 (6.8%) were HIV‐positive. Median plasma HCV RNA was 6.0 log10 IU/mL [IQR = 5.6–6.4]. HCV genotypes identified were 1 (34.8%), 2 (13.7%), 4 (50.9%), 1 and 4 (0.6%); 46 (28.6%) strains of 160 single‐genotype infections were non‐subtypeable. Of 158 treatment completers, 152 (96.2%, 95%CI = 91.9–98.6%) achieved SVR12. Six patients did not achieve SVR12: five carried HCV with NS5A resistance mutations and one with NS5B resistance mutations. Three patients died before and two after treatment completion.

The most common adverse events were asthenia (12.0%), headache (11.4%) and dizziness (18.9%). Conclusion: High cure rates of Hepatitis C with DAAs are achievable in clinical settings of Cameroon. However, the accessibility and provision of HCV screening, diagnosis, treatment, monitoring and care should be addressed for large‐scale implementation. Abstract : Objectifs: Les antiviraux à action directe (AAD) hautement efficaces pour le traitement de l'hépatite C sont largement inaccessibles en Afrique subsaharienne. Les données sur la faisabilité du traitement et les résultats en milieu clinique sont limités. Nous avons évalué la faisabilité d'atteindre un taux de guérison élevé (≥90%) avec les AAD dans six cliniques de gastro‐entérologie au Cameroun. Méthodes: Les patients atteints d'une infection chronique par le virus de l'hépatite C (VHC) ont été traités pendant 12 ou 24 semaines avec le ledipasvir/sofosbuvir, le ledipasvir/sofosbuvir/ribavirine ou le sofosbuvir/ribavirine, selon le stade de la maladie du foie et le génotype du VHC. Le taux de guérison a été défini comme la proportion de patients présentant une réponse virologique soutenue 12 semaines après la fin du traitement (SVR12) parmi tous les patients ayant terminé le traitement. Résultats: Nous avons identifié 190 patients positifs pour l'ARN du VHC entre septembre 2017 et août 2018, dont 161 (84, 7%) ont commencé le traitement. 105 (65, 2%) étaient des femmes, l'âge médian était de 61, 3 ans [IQR = 55, 9‐66, 9] et 11 (6, 8%) étaient positifs pour le VIH. L'ARN plasmatique médian était de 6, 0 log10 UI/mL [IQR = 5, 6–6, 4]. Les génotypes du VHC identifiés étaient 1 (34, 8%), 2 (13, 7%), 4 (50, 9%), 1 et 4 (0, 6%); 46 (28, 6%) souches provenant de 160 infections à génotype unique n'étaient pas sous‐typables. Sur 158 patients ayant terminé le traitement, 152 (96, 2%, IC95%: 91, 9–98, 6%) ont atteint la RVS12. Six patients n'ont pas atteint la RVS12: cinq portaient le VHC avec des mutations de résistance NS5A et un avec des mutations de résistance NS5B. Trois patients sont décédés avant et deux après la fin du traitement. Les événements indésirables les plus courants étaient l'asthénie (12, 0%), les céphalées (11, 4%) et les étourdissements (18, 9%). Conclusion: Des taux élevés de guérison de l'hépatite C avec les AAD sont réalisables dans les milieux cliniques du Cameroun. Cependant, l'accessibilité et la fourniture du dépistage, le diagnostic, du traitement, de la surveillance et des soins du VHC devraient être adressés pour une mise en œuvre à grande échelle. … (more)
