“…Infections in HIV-infected individuals were predominately due to genotype 1a viruses and found only in males possibly reflecting un-reported sex between men. In addition to drug use, the observation of transmission in known HIV positives is not surprising with recent studies from high income countries have demonstrated a high incidence of recent HCV infections in HIV-infected MSMs [8,18,23,[25][26][27][29][30][31][33][34][35][36]. Recent PHE data demonstrated a 21% increase in new HIV infections amongst MSMs in London since 2011 [20].…”

“…Nineteen studies reported the prevalence of HCV infection in high-risk populations: ten were from China [17][18][19][20][21][22][23][24][25][26], two from Japan [27,28], two from Korea [29,30] and five from Taiwan [12,[31][32][33][34]. Among high-risk populations, the prevalence of HCV infection was higher among IDUs (48-95 % in China, Table 4).…”

Hepatitis C virus (HCV) infection is associated with substantial clinical and economic burden and is an important public health issue in Asia. The objective of this review was to characterize HCV epidemiology and related complications in China, Japan, South Korea and Taiwan. A search of electronic databases and conference abstracts identified 71 potentially relevant articles. Of those, 55 were included in the epidemiology review and 9 in the review of HCV-related complications. HCV prevalence in the general population was 1.6% in China, 0.6-0.9% in Japan, 0.6-1.1% in South Korea and 1.8-5.5% in Taiwan. Prevalence was higher for injecting drug users (48-90%) and those with human immunodeficiency virus coinfection (32-85%) and was lower for blood donors (<1%). Annual incidence of HCV in China was 6.01 per 100,000. HCV genotype 1b was associated with the highest incidence of hepatocellular carcinoma (HCC). Five-year survival for patients with liver cirrhosis was 73.8%, decreasing to 39.2% following liver transplantation; the majority of deaths were attributable to HCC. Limitations were that the majority of studies included in the epidemiology review were small, regional studies conducted in specific populations, and there was an absence of large population-based studies. Thus, estimates may not be representative of the epidemiology of HCV for each country. The prevalence HCV in China and HCV incidence in the Asian region remain largely unknown, and they are likely underestimated. Further epidemiologic and clinical data are needed to provide more precise estimates for use by public health agencies.

“…4 Non-IDU HCV acquisition is rarely identified among HIV-negative MSM in Australia and overseas, [98][99][100] with an HCV prevalence of under 1% among HIV-negative non-IDU MSM overseas, arguing against routine HCV testing among HIV-negative MSM. [101][102][103][104] Recently, the US Multicenter AIDS Cohort Study reported an association of incident HCV with higher numbers of receptive unprotected anal intercourse partners, as well as IDU and HIV-positive status. Nonetheless, HCV incidence was only 0.5 per 1000 PY in HIV-negative MSM compared with 4.2 per 1000 PY in HIV-positive MSM.…”

Australian sexually transmissible infection and HIV testing guidelines for asymptomatic men who have sex with men 2014: a review of the evidence

et al. 2014

Abstract.Men who have sex with men (MSM) in Australia and overseas are disproportionately affected by sexually transmissible infections (STIs), including HIV. Many STIs are asymptomatic, so regular testing and management of asymptomatic MSM remains an important component of effective control. We reviewed articles from January 2009-May 2013 to inform the 2014 update of the 2010 Australian testing guidelines for asymptomatic MSM. Key changes include: a recommendation for pharyngeal chlamydia (Chlamydia trachomatis) testing, use of nucleic acid amplification tests alone for gonorrhoea (Neisseria gonorrhoeae) testing (without gonococcal culture), more frequent (up to four times a year) gonorrhoea and chlamydia testing in sexually active HIV-positive MSM, time required since last void for chlamydia first-void urine collection specified at 20 min, urethral meatal swab as an alternative to first-void urine for urethral chlamydia testing, and the use of electronic reminders to increase STI and HIV retesting rates among MSM.

Seroprevalence of hepatitis virus infection in men who have sex with men aged 18–40 years in Taiwan

Abstract: HIV-positive MSM have a higher seroprevalence rate of HBV and HCV infection than HIV-negative MSM in Taiwan. Vaccination and safe-sex counseling should be provided to prevent the transmission of hepatitis viruses among MSM who may be engaged in high-risk behaviors.
