Abstract

Kidney-pancreas (KP) transplantation has been shown to improve left ventricular (LV) geometry and function 6-24 months after the procedure, yet whether these improvements are sustained in long-term survivors has not been demonstrated. This study examined whether early improvements in LV geometry and function were sustained 3-5 years after KP transplantation. Left ventricular function and geometry were prospectively evaluated prior to, and at 1, 2, and 3-5 years posttransplant using two-dimensional, M-mode, echocardiography with Doppler interrogation in the parastemal and apical views. The sample included 21 KP and a comparison group of 12 diabetic kidney-alone (KA) recipients. Long-term (3-5 years) data were obtained for KP recipients only. Although KA recipients had a longer duration of dialysis and worse diastolic function pretransplant, the groups were similar on other baseline measures. KA recipients experienced minimal improvements while KP recipients had significant improvements in cardiac function and geometry, both in terms of mean values and the percentage of KP recipients who experienced normalization posttransplant (p ≤ 0.05), KP recipient improvements were also sustained at 3-5 years posttransplant on three of five measures, with 75% of long-term KP recipients achieving normal LV mass posttransplant compared with 31% pretransplant. Data indicate that significant impairments in cardiac geometry and function occur in diabetic KA and KP recipients. Though both groups experienced early improvements posttransplant, KP recipients achieved more dramatic and clinically significant improvements at 1, 2, and 3-5 years posttransplant. Additional studies are needed to examine the relevance of these findings with regard to the cardiac morbidity and mortality of these patients.
