HIV/HCV coinfected patients more prone to end-stage liver disease without treatment

Individuals coinfected with HIV and hepatitis C virus are more likely to develop end-stage liver disease (ESLD) compared to patients with hepatitis C virus, alone, according to a study presented at the Sixteenth International AIDS Conference in Toronto on August 15th. However, the investigators found that coinfected patients who achieved a sustained response to hepatitis C therapy were no more likely to progress to end-stage liver disease than their hepatitis C monoinfected peers.

Most studies show that coinfected individuals experience more rapid liver fibrosis progression than those with hepatitis C alone, although this may be less likely if they have well-controlled HIV. Coinfected patients are also less likely to respond to interferon-based therapy.

Firouzé Bani-Sadr from INSERM presented data from a study of liver disease progression among co-infected patients in France. The researchers prospectively followed 248 HIV and hepatitis C coinfected participants who received pegylated or conventional interferon, both with ribavirin, for 48 weeks in the RIBAVIC trial. Overall, 29% achieved sustained virological response, or continued undetectable hepatitis C viral load, 24 weeks after the completion of therapy.

The average age of the patients was 42 years, 75% were men, and 59% had hard-to-treat hepatitis C genotypes 1 or 4. Most (81%) were taking potent anti-HIV therapy, about half had HIV viral loads below 200 copies/mL, and the average CD4 cell count was 567 cells/mm3. At the start of the study, 35% already had severe liver fibrosis or cirrhosis.

After an average follow-up period of 33 months, 17 events indicative of end-stage liver disease occurred in nine patients (4%). These events included liver decompensation (with symptoms such as severely elevated bilirubin, ascites, hepatic encephalopathy, or bleeding esophageal varices), hepatocellular carcinoma, need for liver transplant, and liver-related death. Six patients died of liver-related causes and two of other causes.

All cases of end-stage liver disease occurred in patients who did not achieve sustained response to hepatitis C treatment, and all but one occurred in individuals who had advanced fibrosis at the start of the study. End-stage liver disease did not occur in patients with severe fibrosis who permanently cleared hepatitis C with treatment. Among non-responders, end-stage liver disease was more common among patients with advanced fibrosis who also had lower CD4 cell counts.

In a stratified analysis, the only independent risk factors for end-stage liver disease were cirrhosis or severe fibrosis at the start of the study (p<0.001), having a CD4 cell count below 350 cells/mm3 (p=0.022), and lack of sustained virological response to anti-hepatitis C therapy (p=0.068).

In conclusion, the researchers stated, “Our study confirms that the rate of spontaneous hepatic decompensation in coinfected patients with asymptomatic cirrhosis is higher (7.4% per year) than in hepatitis C monoinfected patients (3-4% per year).”

They recommended that, “clinicians should consider the evidence that sustained virological response seems associated with a reduction in long-term morbidity and mortality related to hepatitis C” when discussing treatment options with patients.

Community Consensus Statement on Access to HIV Treatment and its Use for Prevention

Together, we can make it happen

We can end HIV soon if people have equal access to HIV drugs as treatment and as PrEP, and have free choice over whether to take them.

Launched today, the Community Consensus Statement is a basic set of principles aimed at making sure that happens.

The Community Consensus Statement is a joint initiative of AVAC, EATG, MSMGF, GNP+, HIV i-Base, the International HIV/AIDS Alliance, ITPC and NAM/aidsmap
