AIDS 2014: HIV/HCV Coinfected Have High Cure Rates with Interferon-free Hep C Combos

Two studies presented at the 20thInternational AIDS Conference this week in Melbourne showed that all-oral regimens of direct-acting antiviral agents for hepatitis C are safe and effective for HIV positive people. Both regimens demonstrated sustained virological response rates similar to those seen in people with HCV alone.

-- Sofosbuvir + Ribavirin Cures More Than 80% of HIV/HCV Coinfected People

-- AbbVie 3D Regimen Cures Most Genotype 1 HIV/HCV Coinfected Patients

ASCO: HCV Reactivation, Brain Involvement Do Not Worsen Lymphoma Survival for People with HIV

Reactivation of hepatitis C was common among HIV positive people with lymphoma, but did not appear to lead to worse outcomes or decreased survival, according to a study presented at the 50th American Society of Clinical Oncology (ASCO) meeting this week in Chicago. A related study found that having central nervous system involvement at the time of diagnosis did not decrease survival of people with AIDS-related lymphoma.

AIDS 2014: AbbVie 3D Regimen Cures Most Genotype 1 HIV/HCV Coinfected Patients

An all-oral regimen of 3 direct-acting antivirals plus ribavirin taken for 12 weeks demonstrated a sustained virological response rate of 94% for people coinfected with HIV and genotype 1 hepatitis C in the TURQUOISE-I study, according to a late-breaking report at the 20th International AIDS Conference (AIDS 2014) this week in Melbourne, Australia.

Hepatitis C Cascade Studies Show Gaps in Testing and Treatment

About half of people with hepatitis C are aware of their infection but less than 10% have been successfully treated and achieved sustained virological response, according to a meta-analysis presented at the recent Conference on Retroviruses and Opportunistic Infections (CROI 2014). A related study found that among HIV/HCV coinfected people, 40% had been referred to hepatitis C care but only 4% were cured.

AIDS 2014: Sofosbuvir + Ribavirin Cures More Than 80% of HIV/HCV Coinfected People

An interferon-free regimen of sofosbuvir (Sovaldi) plus ribavirin for 24 weeks led to sustained virological response in 84% to 89% of HIV positive chronic hepatitis C patients with HCV genotypes 1, 2, 3, or 4, according to results from the PHOTON-2 study presented at the 20th International AIDS Conference in Melbourne, Australia. Cure rates were lower, however, for genotype 1a patients with liver cirrhosis.

CROI 2014: How Fast Does Fibrosis Progress in Acute Hepatitis C Patients with and without HIV?

Liver disease was found to progress slowly in studies of both HIV negative people with newly acquired hepatitis C virus (HCV) and HIV/HCV coinfected people with acute HCV, according to a pair of studies presented at the recent Conference on Retroviruses and Opportunistic Infections.

Studies Look at Hepatitis C Care Cascade and Healthcare Utilization

Half of people with hepatitis C in the U.S. are aware of their infection, but fewer than 10% have been successfully treated and achieved sustained virological response (SVR), according to a meta-analysis published July 2 in the open-access journal PLoS ONE. Despite these gaps in testing, care, and treatment, hepatitis C accounts for a substantial share of healthcare utilization, especially among baby boomers, a related study found.

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.
