Dr. Fierer sees patients for infectious diseases, specializing in HIV and/or Hepatitis C Virus infection and also sees patients with or at risk for HIV/AIDS in the Jack Martin Fund Clinic.
Dr. Fierer's research interests are focused on the study of acute Hepatitis C (HCV) infection in HIV-infected patients. Hepatitis C infection is highly prevalent in HIV-infected people, but Hepatitis C is rarely diagnosed during the acute phase (first 6 months) of infection and so little is known about the early course of Hepatitis C infection. Further, people who are already HIV-infected at the time they contract HCV infection may be at particular risk of having significant liver disease: a preliminary study in collaboration with Drs. Branch and Dieterich showed the presence of moderately advanced liver damage in HIV-infected people who have acute HCV infection. Dr. Fierer has initiated a larger study to evaluate HIV-infected patients referred by their physicians for acute HCV infection to further investigate the early effects of this infection on liver pathology, on the natural history of the disease, on the effectiveness of treatment, and of the mode of transmission.
