Dr. Dienstag's primary research interest is in viral hepatitis. Among his contributions have been basic virologic, experimental animal-model, immunologic and immunopathogenetic, genetic, epidemiologic, vaccination and antiviral studies of hepatitis A, B, C, and D viruses.
Dr. Dienstag's recent research efforts have focused on antiviral therapy for chronic viral hepatitis. Dr. Dienstag has participated in clinical trials of interferon therapy for chronic hepatitis C; in combination with the nucleoside analog ribavirin; in naive, relapsing and nonresponder patients; with different formulations of standard interferon; with long-acting, pegylated, preparations and with directly acting antiviral agents (e.g., protease inhibitors).
Dr. Dienstag led one of 10 Clinical Center teams nationwide in an multiyear trial of protracted antiviral therapy for patients refractory to treatment for chronic hepatitis C. This study, designated the HALT-C (Hepatitis Antiviral Long-term Treatment against Cirrhosis) Trial, was designed to test the hypothesis that long-term interferon therapy, even in biochemical/virologic nonresponders to interferon, can limit histologic and clinical progression. The HALT-C Trial also included a series of ancillary studies that defined virologic alterations during protracted therapy and during the natural progression of disease and provided a rich source of clinical material, which shed light on the process of fibrosis and hepatocarcinogenesis.
Dr. Dienstag was the leading US academic clinical investigator in the development of lamivudine as the 1st approved orally administered nucleoside analog for the treatment of chronic hepatitis B.
