Heart transplantation in diabetic recipients.
Preexisting diabetes mellitus (DM) has been regarded as a contraindication to heart transplantation (HT). This prejudice has been based upon concern over increased infection rates and worsening DM with the initiation of prednisone immunosuppression. To better evaluate these suppositions, we reviewed our experience with diabetic patients who underwent HT. Between 6/80 and 1/88, 367 nondiabetics (NDs) and 19 diabetics underwent HT at our institution. Of the 19 diabetic recipients (DRs), two were black and four were female. Six DRs were on insulin (average daily dose: 46 U) prior to HT, and the remainder required oral hypoglycemic agents. Following HT, five DRs had insulin substituted for oral hypoglycemics. The 11 insulin-dependent DRs now require an average daily dose of 48 U. The average duration of follow-up for the 19 DRs was 17 months (range 1-67 months). During this time, 5 hospitalizations were required for complications of diabetes. The rejection rate was not higher for the DRs than the NDs (0.37 events/100 pt. days vs. 0.51 events/100 pt. days). The DRs who have undergone coronary angiography up to 4 years following HT have had no evidence of coronary atherosclerosis. Three-year survival for DRs and NDs is similar. DRs have a slightly higher incidence of lethal infections than NDs, which is not statistically significant (16% at 17 months vs. 10% (p greater than 0.4). We conclude that carefully selected diabetics can undergo HT with minimal consequent worsening of their DM. Diabetic HT recipients do not suffer a higher incidence of graft atherosclerosis, rejection, or lethal infection.
