HIV, HBV and HCV Coinfection Prevalence in Iran--A Systematic Review and Meta-Analysis.

Bagheri Amiri F, Mostafavi E, Mirzazadeh A - PLoS ONE (2016)

Bottom Line: HIV prevalence varied from %0.00 (95% CI: 0.00-0.003) in the general population to %17.25 (95% CI: 2.94-31.57) in people who inject drugs (PWID).HBV prevalence ranged from % 0.00 (95% CI: 0.00-7.87) in health care workers to % 30.9 (95% CI: 27.88-33.92) in PWID.HCV prevalence ranged from %0.19 (95% CI: 0.00-0.66) in health care workers to %51.46 (95% CI: 34.30-68.62) in PWID.

ABSTRACT

Background: worldwide, hepatitis C and B virus infections (HCV and HCV), are the two most common coinfections with human immunodeficiency virus (HIV) and has become a major threat to the survival of HIV-infected persons. The review aimed to estimate the prevalence of HIV, HBV, HCV, HIV/HCV and HIV/HBV and triple coinfections in different subpopulations in Iran.

Method: Following PRISMA guidelines, we conducted a systematic review and meta-analysis of reports on prevalence of HIV, HBV, HCV and HIV coinfections in different subpopulations in Iran. We systematically reviewed the literature to identify eligible studies from January 1996 to March 2012 in English or Persian/Farsi databases. We extracted the prevalence of HIV antibodies (diagnosed by Elisa confirmed with Western Blot test), HCV antibodies and HBsAg (with confirmatory laboratory test) as the main primary outcome. We reported the prevalence of the three infections and coinfections as point and 95% confidence intervals.

Findings: HIV prevalence varied from %0.00 (95% CI: 0.00-0.003) in the general population to %17.25 (95% CI: 2.94-31.57) in people who inject drugs (PWID). HBV prevalence ranged from % 0.00 (95% CI: 0.00-7.87) in health care workers to % 30.9 (95% CI: 27.88-33.92) in PWID. HCV prevalence ranged from %0.19 (95% CI: 0.00-0.66) in health care workers to %51.46 (95% CI: 34.30-68.62) in PWID. The coinfection of HIV/HBV and also HIV/HCV in the general population and in health care workers was zero, while the most common coinfections were HIV/HCV (10.95%), HIV/HBV (1.88%) and triple infections (1.25%) in PWID.

Conclusions: We found that PWID are severely and disproportionately affected by HIV and the other two infections, HCV and HBV. Screenings of such coinfections need to be reinforced to prevent new infections and also reduce further transmission in their community and to others.

Mentions: As presented in Fig 1, we found 302 abstracts in our literature review. After removing duplications (167) based on title and abstract, 135 remained for fulltext review. Of those, 83 articles were excluded (S1 Table) for various reasons including poor quality (3), no report of coinfections (38), unclear serologic tests (15), fulltext was not available (4), no serology test (2), only recruited HIV positive cases (15) no confirmatory lab test results (6), and specific subpopulations not listed in the six population categories we have chosen as priori (3).
