1.  HIV Monoinfection Is Associated With Increased Aspartate Aminotransferase-to-Platelet Ratio Index, a Surrogate Marker for Hepatic Fibrosis 
The Journal of Infectious Diseases  2012;205(6):1005-1013.
Background. Although liver disease commonly causes morbidity and mortality among human immunodeficiency virus (HIV)–infected individuals, data are limited on its prevalence in HIV monoinfection. We used the aspartate aminotransferase-to-platelet ratio index (APRI) as a surrogate marker of hepatic fibrosis to characterize liver disease in the Multicenter AIDS Cohort Study.
Methods. Men were categorized based on their HIV and viral hepatitis status: uninfected (n = 1170), HIV monoinfected (n = 509), viral hepatitis monoinfected (n = 74), and HIV–viral hepatitis coinfected (n = 66).
Results. The median APRI in the HIV-monoinfected group was similar to that in the hepatitis-monoinfected group (0.42 vs 0.43; P > .05), higher than in the uninfected group (0.42 vs 0.27; P < .001) but lower than in the coinfected group (0.42 vs 1.0; P < .001). On multivariable analysis, HIV infection (1.39-fold increase [FI]; P < .001), viral hepatitis infection (1.52-FI; P < .001), and the interaction between HIV and viral hepatitis infections were independently associated with a higher APRI (1.57-FI; P < .001). Among the HIV-infected men, viral hepatitis coinfection (2.34-FI; P < .001), HIV RNA ≥100 000 copies/mL (1.26-FI; P = .007), and CD4 count ≤200 cells/mL (1.23-FI; P = .022) were independently associated with a higher APRI.
Conclusions. HIV and viral hepatitis are independently associated with an increased APRI. Further studies are needed to understand the biological basis for the association between HIV and liver disease.

2.  Hepatitis B and long-term HIV outcomes in co-infected HAART recipients 
AIDS (London, England)  2009;23(14):1881-1889.
Chronic hepatitis B (CH-B) is common among HIV-infected individuals and increases liver-related mortality in the absence of highly active antiretroviral therapy (HAART). The impact of CH-B on long-term HAART outcomes has not been fully characterized.
Methods
To address this question, HAART initiators enrolled in the Multicenter AIDS Cohort Study (MACS) were retrospectively analyzed. Subjects were classified by hepatitis B category based on serology at the time of HAART initiation. The association of CH-B with mortality, AIDS defining illnesses, CD4 rise, and HIV suppression was assessed using regression analysis.
Results
Of 816 men followed for a median of 7 years on HAART, 350 were never HBV infected, 357 had past infection, 45 had CH-B, and 64 were only core-antibody positive. Despite HAART, AIDS-related mortality was the most common cause of death (8.3/1000 person-years (PYs)). It was highest in those with CH-B (17/1000 PYs, 95% CI 7.3, 42) and lowest among never HBV infected (2.9/1000 PYs, 95% CI 1.4, 6.4). In a multivariable model, patients with CH-B had a 2.7-fold higher incidence of AIDS-related mortality compared to those never infected (P=0.08). Non-AIDS-related mortality was also highest among those with CH-B (22/1000 PYs), primarily due to liver disease (compared to never infected, adjusted HR 4.1, p=0.04). There was no significant difference in AIDS defining events, HIV RNA suppression, and CD4 increase.
Conclusion
In HIV-infected patients receiving long-term HAART, HBV status did not influence HIV suppression or CD4 increase. However, mortality was highest among those with CH-B and was mostly due to liver disease despite HBV-active HAART.
