P1099 EXPRESSION OF NK CELL RECEPTORS AS A PREDICTOR OF TREATMENT RESPONSE IN CHILDREN WITH CHRONIC HEPATITIS C

Objectives: To determine efficacy of sofosbuvir and daclatasvir in the treatment of chronic hepatitis C infection. Study Design: Open label uncontrolled interventional study. Setting: Hepatitis Clinic, Sheikh Zayed Medical College/Hospital, Rahim Yar Khan. Period: June to December 2018. Material & Methods: Five hundred treatment naïve chronic hepatitis C patients including those with compensated cirrhosis were included in the study. They were given sofosbuvir 400 mg daily and daclatasvir 60 mg daily. Weight based ribavirin was added if patient has evidence of cirrhosis. Treatment duration was 12 weeks for non-cirrhotic and 24 weeks for cirrhotics. End of treatment response (ETR) was recorded. Results: Mean age of the included patients was 41±11.69 with range from 8 to 82 years, while 217 (43.4 %) patients were male and 283 (56.6 %) were female. Cirrhosis was present in 59 (11.8 %) patients; among these 35.6 % were in Child A and 64.4 % in early Child B. End of treatment response occurred in 491 (98.2 %) patients and there was no significant difference in ETR between male and female patients, and between cirrhotic and non-cirrhotic. Similarly, there was no significant difference in age between those having ETR and those having no ETR. Fatigue was experienced by 13.2 % and headache by 4.2 % patients. Conclusion: The combination of sofosbuvir and daclatasvir has high response rate in chronic hepatitis C patients of our population.

Viral Response

Chronic viral infections affecting the liver represents a global burden for medical comunities. More than 170 million individuals are infected chronically with hepatitis C virus (HCV), this accounting about 2�3% of the world�s population. Despite numerous progresses aquired in viral pahogenesis and treatment, chronic hepatitis C management is influenced by a multitude of factors. Interleukin IL-28 beta subunit (IL28B) demonstrated to be involved in both sustained virological response (SVR) to treatment, but even with spontaneous viral clearance without any therapy. In the era of direct antiviral agents (DAAs) we aimed to find out what was the real influence of IL28B phenotypes over the response to Peg-IFN and Ribavirin treatment in patients with chronic hepatitis C, many of theses being non-responders or relapsers, and as consequence, to optimize the referal of patients to more expensive and efficient treatments. In a retrospectively manner, we analyzed the IL28B phenotype and its influence over the rapid viral response (RVR), early viral response (EVR) and sustained viral response (SVR), in 250 patients HCV treated patients. We made correlations between the treatment response rates and the IL28B polymorphism.TT phenotype was correlated negatively with all parameters studied, while CC phenotype was correlated with the best response rates. We concluded that IL28B phenotypes interfere with the EVR and SVR rates, IL28B phenotype being an independent prognostic factor for antiviral treatment response in our patient groups, and according to this characteristics, we created the premise to optimize the patients referal to expensive therapies as DAAs.
