Description of Research Expertise

Research Interests
- Hepatic and non-hepatic outcomes of chronic hepatitis B and C, particularly among patients with HIV infection
- Adherence to hepatitis C virus therapy
- Hepatotoxicity of medications
- Evaluation of clinical outcomes
- Population-based and administrative databases

Key Words
HIV/viral hepatitis coinfection; hepatitis B; hepatitis C; HIV/AIDS; epidemiology; clinical outcomes; pharmacoepidemiology

Description of Research
Dr. Lo Re’s research focuses on clinical outcomes of chronic viral hepatitis infection in HIV-infected patients. He is conducting epidemiologic studies to examine novel risk factors for decompensated cirrhosis among HIV/hepatitis C-coinfected patients and is working to develop and internally validate a clinical predictive index to stratify HIV/hepatitis C patients according to their risk of progression to hepatic decompensation. He has also examined the prevalence, risk factors, and clinical significance of occult hepatitis B virus infection in HIV-infected patients. Additional studies are examining non-hepatic outcomes of chronic viral hepatitis infection in HIV, particularly abnormalities in bone mineral density and fractures.

Dr. Lo Re also evaluates clinical outcomes of hepatitis therapy in the setting of HIV. Recent work has examined the incidence and risks factors for anemia and weight loss during hepatitis C therapy among HIV-infected patients. Another active area of research is adherence to combination pegylated interferon and ribavirin hepatitis C therapy, specifically examining the levels of adherence required for maximal hepatitis C suppression and risk factors for poor adherence to these therapies.

Methodologic interests include use of population-based databases for epidemiologic research, ascertainment and adjudication of clinical outcomes, and pharmacoepidemiology.
