Reginald Y. Gohh Associate Professor of Medicine

I have been involved in the Kidney Transplant Program as its Medical Director at RIH since its inception in 1996. During that time, I have been involved in the care of approximately 600 new transplant patients. I have also been involved in the training of over 25 renal fellows as well as providing education to both the medical and surgical housestaff. I have co-authored over 40 peer-reviewed scientific papers. My primary research interests include different aspects of clinical transplantation. These include pharmacokinetic studies of various immunosuppressive medications and how these may effect different transplant populations. I have also pursued studies that helped to identify and treat patients at increased risk for recurrent primary renal disease in the post-transplant setting.

research overview

I am interested in learning why some immunosuppressive drugs are more effective in preventing rejection in certain patient populations compared to others, with a specific interest in the diabetic population. I am also involved in studies which look at the most effective immunosuppressive drug combinations in preventing rejection and long-term outcomes. Other studies focus on the the effect of kidney transplantion on the quality of life of these unfortunate patients.

research statement

I have involved in a number of industry-sponsored, multi-centered studies looking at the effectiveness of different immunosuppressive drug regimens in not only preventing allograft rejection, but also long-term outcomes. More recently, I have focused my attention on the pharmacokinetic and pharmacodynamic properties of different immunosuppressive agents in different study populations. I am particularly interested in learning more about the diabetic population, since these individuals are more prone to complications post-transplantation. In addition, I am currently performing a study looking at howcorrecting uremic physiology affects quality-of-life paramaters such as exercise tolerance.
