Summary: | Hepatitis C virus (HCV) infection is considered a major health problem recognized globally. HCV is a major cause of chronic liver disease that may lead to cirrhosis and hepatocellular carcinoma. The aim of this study was to investigate the prevalence of multiple (mixed) HCV genotypes in Saudi patients recently diagnosed with HCV infection and their association with various clinical risk factors. We examined a total of 1, 292 newly diagnosed HCV-positive cases between January 2006 and July 2009 at the Molecular Pathology Laboratory, King Abdulaziz Medical City, Riyadh. The clinical and laboratory data of the study patients were collected. The HCV-RNA viral load and its genotyping were carried out with RT-PCR technology to assist in the follow-up and management of HCV-infected patients undergoing antiviral therapy. Twenty-two patients (1.7%) were found to have mixed HCV genotypes; of them, mixed genotypes associated with genotype-4 were seen in 19 patients (86%), mixed genotypes associated with genotype-1 were found in 68.4%, with genotype-3 in 26.3% and with genotype-2 in 5.3%. Additionally, mixed genotypes associated with genotype-1 were seen in three cases (13.6%); they were associated with genotype-2 in two (66.7%) and with genotype-5 in one patient (33.3%). In conclusion, the prevalence rate of mixed HCV genotypes in the cohort of the newly infected Saudi patients was 1.7%, with genotype-4 being the most frequent genotype encountered. |
