Retrospective analysis of early steroid-induced adverse reactions in kidney and kidney-pancreas transplant recipients

Corticosteroids (steroids) are associated with numerous adverse drug reactions (ADRs). Long-term ADRs are well characterized, but there are limited data on the incidence and likelihood of short-term ADRs. We sought to determine the incidence of ADRs potentially related to early administration of steroids in kidney and kidney-pancreas transplant recipients and to determine the probability that the ADR was due to the steroid. We retrospectively evaluated the records of all eligible kidney or pancreas-kidney transplants during 2003. ADRs were rated by two reviewers according to the Naranjo algorithm, and identified as "definite," "probable," "possible," or "doubtful." ADRs were identified in 100% of patients (n = 103) by 8.2 +/- 4.9 days. The mean ADRs per patient were 3.26 +/- 1.04. Weight gain occurred in 79.6%, hypertension in 71.8%, diabetes mellitus in 52.4%, hyperglycemia in 47.6%, leukocytosis in 31.1%, insomnia in 27.2%, anxiety in 10.7%, and psychosis in 1.9%. Based on mean interinvestigator score, leukocytosis was judged as "probable" and weight gain and psychosis were "possible to probable." Diabetes, hyperglycemia, hypertension, and insomnia were "possible" and anxiety was "possible to doubtful." These results provide evidence of the incidence and likelihood of early steroid-related ADRs.
