A Rare Case Report: Hemodynamic Responses and Exercise Capacity Before and After Becoming a Non-Biological Live Liver Donor

Abstract

According to the United States Department of Health and Human services 8,497 liver transplants were accomplished in the United States in 2016. Of those transplants, only 345 (4.1%) of the transplants came from a live donor and only 9 (0.03%) of the live donor transplants came from a nonbiological paired donor [1]. Very little published data exists regarding Living Donor Liver Transplant (LDLT) influences on the live donor’s responses to exercise post-surgery. Purpose: To study the acute and prolonged effects of exercise and LDLT on heart rate, blood pressure, Lactate, Glucose, estimated maximal aerobic capacity, muscular strength, and the responses during submaximal exercise testing (6MWT and/or submaximal Bruce protocol). Methods: A single female subject, age 53 years, volunteered to participate in this study after already agreeing to become a live liver donor. Data was obtained once prior to the procedure and every month thereafter, for a total of eight months post-surgery. Conclusions: There was minimal changes in aerobic capacity and strength due to lack of consistency with an exercise program. Findings of this case report 
cannot be generalized to all LDLT donors. However, the information on the recovery of an LDLT donor in respect to exercise testing may be beneficial to clinicians and professionals in prescribing an exercise program for similar patients in similar circumstances.
