Recurrence of hepatitis C virus after treatment with pegylated interferon and direct acting antivirals in Punjab Pakistan

Although increased response rates concomitant in hepatitis C virus but relapse after treatment is threatened. Therefore, it is terrible requirement to evaluate the response of Pegylated interferon and direct acting antivirals in Punjab Pakistan. The study was conducted to find the rate of recurrence of HCV infection after treatment with Pegylated Interferon and Direct Acting Antivirals in Punjab Pakistan. This study was conducted at Department of Pathology, Nawaz Sharif Medical College Gujrat, while treatment effects monitored in different Government and Private Hospitals of Punjab, Pakistan. Total 973 patients who administered the recommended dose and divided in two groups (i) Interferon based therapy (ii) direct acting antivirals (DAAs).Other parameters like ALT and viral load studied. The rate of recurrence was higher in female infected with genotype 2b and in male with mixed genotype 3a/2b after six month of antiviral therapy. Genotype 3a showed significant response to therapy after three month. 32 among 374 (8.5%) were positive after 24 weeks of treatment with interferon, 29 (7.7%) patients have same genotype while 3 patients were re-infected with different HCV strains. With DAAs, only 27 (4.8%) patients were positive among 558 after 2 weeks and one patient re-infected with different genotype. Early and sustained virological response noted in DAAs. ALT and viral load decreased faster with DAAs that not achieved after 4 weeks with pegylated interferon. Sustained virological response appears in DAAs and recurrence rate is high in interferon therapy compared to DAAs. Therefore, reinfection has implications for correct treatment efficiency and to select strategies for retreatment cases.

Prevalence of active HCV infection and genotypic distribution among the general population of district Mardan, Pakistan

Hepatitis C virus (HCV) is the serious global public health burden of liver disease. Approximately 170 million people in the world are infected with (HCV). In Pakistan, where the disease has high occurrence rate. The present study envisages an up-to-date prevalence of HCV and genotypic distribution in the general population of Mardan District, Khyber Pakhtunkhwa (KP), Pakistan. The blood samples from 6,538 individuals including 3,263 males and 3,275 females were analyzed for hepatitis C surface antigen by Immuno-chromatographic test (ICT), Enzyme-linked immunosorbent assay (ELISA), and reverse transcription-polymerase chain reaction (PCR). It was found that 396 (12.13%) out of 3263 individuals contained antibodies in their blood against HCV, while among the different age groups, the highest incidences of HCV antibodies were found in the 31-40 age group (11.01%). The ICT positive samples were further screened by nested PCR to determine the existence of active HCV-RNA. It was identified that 7.11% (3263) of the total population (6538) tested was positive, among which the 461 (14.07%) females possessed antibodies in their blood against HCV. Our data showed total HCV infection in the investigated population was 5.78%. Higher percentage of HCV prevalence was detected in males than females in the age group 31-40 and 41-50. To compare the prevalence of HCV genotypes age-wise in male and female genotype 3a was found most prevalent genotype followed by 1a, 2a and 3b, respectively.
