Antiretroviral Effects on Host Lipoproteins Are Associated With Changes in Hepatitis C Virus (HCV) RNA Levels in Human Immunodeficiency Virus/HCV Coinfected Individuals.

Dr. Susanna Naggie completed her undergraduate degrees in chemical engineering and biochemistry at the University of Maryland, College Park, and her medical education at Johns Hopkins School of Medicine. She conducted her internal medicine and infectious diseases fellowship training at Duke University Medical Center, where she also served as Chief Resident. She joined the faculty in the Duke School of Medicine in 2009. She is a Professor of Medicine and currently holds appointments at the Duke University School of Medicine, at the Duke Clinical Research Institute, and at the Durham Veterans Affairs Medical Center. Dr. Naggie is a clinical investigator with a focus in clinical trials in infectious diseases and translational research in HIV and liver disease. She is a standing member of the DHHS Panel on Antiretroviral Guidelines for Adults and Adolescents and the CDC/NIH/IDSA-HIVMA Opportunistic Infections Guideline. She is the Vice Dean for Clinical and Translational Research and Director for the Duke Clinical and Translational Sciences Institute.

My research interest includes statistical methodology development and application in the area of biopharmaceutical/clinical statistics such as bioavailability and bioequivalence, clinical trials, bridging studies, medical devices, and translational research/medicine. Most recently, I am interested in statistical methodology development for the use of adaptive design methods in clinical trials and methodology development for assessment of biosimilarity of follow-on biologics. In addition, I am also interested in methodology development for statistical evaluation of traditional Chinese medicine (TCM) clinical trials.

Current research efforts focus on the role of niacin in clinical lipid practice. Despite the ending of a large clinical trial due to lack of benefit, niacin remains the second best lipid-modifying drug after statins. Why this trial did not replicate earlier success with niacin is a matter of great interest. Counterregulatory hormone responses may provide the answer. Another research focus is weight loss counseling in the busy clinic setting. Low glycemic dietary advice achieved average long-term weight loss of 3% (beyond 1 year) in a recently published study. One in four patients had long-term weight loss greater than 6%.

Dr. Guyton is recognized nationally as an expert in clinical management of lipid disorders and a leader in postgraduate education in this area. Both nationally and internationally, Dr. Guyton is known for his earlier work on lipid deposition in the arterial wall.
