Abstract

Background: One of the most important causes of chronic liver disease is hepatitis C virus (HCV), which causes liver cirrhosis and hepatocellular carcinoma. To control the prevalence of the disease, knowledge and information in risk factor of HCV are required. The aim of this study was to compare the risk factors of infection between HCV patients with genotypes 1a and 3a. Methods: This is an observational analytical study. HCV patients who referred to the clinic of hepatology, Rasoul-e-Akram University Hospital from July 2015 to July 2017, were assigned to the genotype 1a and 3a. Demographic (age, sex, family history), clinical (cirrhosis, hepatocellular carcinoma) and laboratory data, history of intravenous drug and alcohol usage, and history of imprisonment were gathered and compared between two groups. All the patients completed the informed consent form. Data analysis was performed by SPSS software, version 22 (IBM SPSS, Armonk, NY, USA). P value less than 0.05 was considered statistically significant. Results: Overall, 97 HCV patients were included in this study. Mean age was 45±12 years and 78 (80) of patients were male. Among them, 58 (60) and 39 (40) had genotype 1a and 3a. respectively. History of injection drug usage was recorded in 34/39 (87) of patients with genotype 3a, and significantly higher in genotype 3a as compared to genotype 1a OR adj: 3.1, CI (1.3-6.2). Also, in this study, genotype 3a was significantly recorded in younger patients OR adj: 1.7, CI (1.2-4.1). However, cirrhosis and hepatocellular carcinoma was more common in patients with genotype 1a as compared to genotype 3a OR adj: 2.05, CI (1.6-5.4) and OR adj: 2.8, CI (1.3-5.7) respectively. Conclusion: According to the results of this study, hepatitis C virus transmission risk factors differed in genotypes 3a and 1a. Genotype 3a is found among young patients with a history of intravenous drug usage and genotype 1a in patients with cirrhosis and hepatocellular carcinoma. © 2018, Tehran University of Medical Sciences.
