Abstract
To calculate the prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infections among inpatient heroin users, and to study the relationships between these infections and patient demographics.
In this retrospective study, heroin users' inpatient records from the Alamal Hospital, Riyadh, Saudi Arabia were reviewed for HIV, HBV, and HCV screening results, age, number of admissions, education, and marital and occupational status. The study took place between January 2006 and November 2012. The prevalences of HIV, HBV, and HCV and their associations to demographics were evaluated.
A sample of 357 inpatients Saudi male heroin users (all injectors) aged 40 (±8.6) years with lifetime admissions averaged 5.8 (±5) times were studied. Screening results revealed that 20.1% of subjects were infection-free, 56.6% had a single infection, 13.2% were infected by 2 viruses, and 1.1% were infected by 3 viruses. Prevalence of HBV surface antigen was 7.7%, antibodies for HCV 77.8%, and HIV 9.8%. A significant association was found between positive HCV and positive HIV tests. Furthermore, HCV was more common among patients aged 20-29 years, those who were unemployed, and who had primary, secondary, or postsecondary education. Finally, HBV was associated in patients aged 30-39 years and those with secondary educations.
Contracting serious contagious viral infections is very common among Saudi heroin injectors at rates similar to those seen among injectors in Western countries. Infection control, education, and harm reduction programs are of paramount importance.
