HIV-Negative Gay Men May Be Susceptible to Sexually Transmitted Hepatitis C

Several studies have shown that hepatitis C virus (HCV) can be sexually transmitted among HIV-positive men who have sex with men, but HIV-negative gay and bisexual men may be at risk as well if they share similar risk factors, according to a report in the June 2015 Journal of Viral Hepatitis.

EASL 2015: Hepatitis C Treatment Could Cut HCV Transmission Among UK Gay Men in Half

Access to more effective hepatitis C treatment could reduce new infections among men who have sex with men in the United Kingdom by half over the next decade, according to a mathematical modeling study presented at the European Association for the Study of the Liver (EASL) International Liver Congress in Vienna in April.

EASL 2014: Treatment as Prevention for Drug Users Could Slash HCV Prevalence

A combination of increased testing, improved linkage to care, and earlier treatment with interferon-free regimens has the potential to substantially reduce the incidence and prevalence of hepatitis C among people who inject drugs in France over the next 10 years, as well as reducing the burden of disease arising from cirrhosis over 40 years, according to a study presented at the 49th EASL International Liver Congress (EASL 2014) last week in London.

EASL 2015: Reinfection after HCV Cure - Long-term Support Needed for People Who Have Injected Drugs

Reinfection rates after a hepatitis C cure among people who inject drugs, as well as past drug users, are relatively low, according to findings from studies from Norway and Canada presented at the European Association for the Study of the Liver (EASL) 50th International Liver Congress in Vienna in April. The findings suggest that current and former injection drug users who have been cured of hepatitis C require ongoing support to remain free of HCV, but also indicate that fears of a high rate of reinfection should not be used as a reason to withhold hepatitis C treatment from people who inject drugs.

AASLD 2013: HCV Levels in Semen May Correspond to Blood Viral Load

HIV positive men with higher hepatitis C virus (HCV) RNA levels in their blood during acute infection were more likely to have HCV in their semen as well, which may raise the risk of sexual transmission, researchers reported last month at the 64thAASLD Liver Meeting in Washington, DC.

EASL 2015: Civacir Immune Globulin May Help Prevent HCV Reinfection after Liver Transplant

Civacir, a hepatitis C immune globulin or antibody product, reduced the likelihood of hepatitis C virus infecting the new liver graft after transplantation in patients who were receiving but had not yet completed antiviral treatment, according to preliminary study findings presented at the European Association for the Study of the Liver (EASL) 50th International Liver Congress last month in Vienna.

Hepatitis C Virus Can Live on Surfaces for Up to 6 Weeks

Hepatitis C virus (HCV) in dried droplets of blood or plasma can remain infectious on uncovered surfaces at temperatures of 4° or 22° C (39° or 72° F) for up to 6 weeks, resulting in potential for transmission in healthcare settings or during injection drug preparation, researchers reported in the November 23, 2013, advance edition of the Journal of Infectious Diseases.

CROI 2015: HCV Sexual Transmission Linked to Anal Sex, Drug Use, Lower CD4 Count

In addition to the usual risk factors for hepatitis C virus (HCV) sexual transmission seen in most previous studies -- such as anal sex and having other sexually transmitted infections -- researchers in the Netherlands also saw an association with nasal and injection drug use and lower CD4 T-cell count, they reported in a poster presentation at the recent 2015 Conference on Retroviruses and Opportunistic Infections (CROI) in Seattle.

Injection Drug Users Who Know They Have Hepatitis C Practice "Sero-Sharing"

People who inject drugs who know they are hepatitis C virus (HCV) positive are more likely to share syringes and injection equipment with others who are also infected, and less likely to do so with people who are HCV negative or unknown -- the equivalent of sexual "serosorting," according to a report in the December 15, 2013, Journal of Infectious Diseases.

ICAAC 2013: Is HCV Infection Increasing Among HIV+ Gay Men in Japan?

The incidence of acute hepatitis C virus (HCV) coinfection has increased in recent years at the largest HIV clinic in Japan, with almost all cases occurring among men who have sex with men, according to a poster presented at the 53rd Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC 2013) this month in Denver. For those treated early with pegylated interferon plus ribavirin, the cure rate was high at 80%.

Hepatitis C Vaccine Is Safe and Induces Immune Responses in Early Human Trial

A new hepatitis C vaccine demonstrated good safely and tolerability in a first-in-humans Phase 1 clinical trial, with only mild and transient side effects, according to a report in the November 5 edition of Science Translational Medicine. The vaccine, which mimics immune responses in people who naturally clear hepatitis C virus (HCV) infection, led to increased production of T-cells targeting the virus. Phase 2 studies are now underway in Baltimore and San Francisco, with results expected in 2016.

HCV Sexual Transmission: HIV Negative May Be at Risk, More Awareness and Testing Needed

Hepatitis C virus (HCV) is known to be sexually transmitted among HIV positive men who have sex with men, but HIV negative men may be at risk as well, according to recent reports. Other recent studies have looked at awareness of HCV sexual transmission and screening practices, suggesting that improvement is needed in both areas.

July 28 Is World Hepatitis Day [VIDEO]

July 28 is World Hepatitis Day, an opportunity to raise awareness about viral hepatitis and its consequences. This year's theme -- "Think Again" -- emphasizes that while hepatitis B and C are major causes of death worldwide, viral hepatitis remains remarkably neglected. The World Health Organization (WHO) and others held a press briefing at the 20th International AIDS Conference last week in Melbourne to raise awareness.

Antiretroviral PrEP Prevents HIV Transmission among Injection Drug Users

Pre-exposure prophylaxis (PrEP) using daily oral tenofovir (Viread) reduced the risk of HIV acquisition among injection drug users in Thailand by half, according to findings from the Bangkok Tenofovir Study, published in the June 13, 2013, advance online edition of The Lancet. These findings led the CDC to recommend that PrEP be "considered as one of several prevention options for persons at very high risk for HIV acquisition" through injection drug use.alt

Studies Shed Light on Hepatitis C Virus Sexual Transmission among Gay Men

Hepatitis C virus (HCV) transmission among HIV positive gay men has leveled off in Amsterdam -- one of the first cities with an outbreak of apparently sexually transmitted HCV infection -- and it continues to be rare among HIV negative men who have sex with men, according to recent studies. Other research looked at HCV sexual transmission among HIV positive and negative men in Switzerland, and at the association between HCV viral load in blood and semen.

War on Drugs Is Major Driver of Global Hepatitis C Epidemic

The so-called "war on drugs" plays a major role is sustaining hepatitis C epidemics worldwide, including in hard-hit Russia and Eastern Europe, according to the latest report from the Global Commission on Drug Policy. Drug prohibition drives drug users underground and blocks harm reduction efforts such as needle exchange programs. "The war on drugs is a war on common sense," said Commissioner Ruth Dreifuss.alt
