The use of the drug cyclosporin is limited by toxicity. It would be advantageous to develop therapeutic monitoring of cyclosporin which would predict the development of clinical toxicity. In the present study, alternative methods of measuring cyclosporin levels were evaluated in a heterogenous population of transplant patients, comparing a fluorescent polarization immunoassay using a non-specific polyclonal antibody, which measures both cyclosporin and its main metabolites, and a specific high-performance liquid chromatography assay for unchanged cyclosporin in blood. Neither measured variable alone correlated with laboratory evidence of renal toxicity (serum creatinine) or liver toxicity (serum glutamate transaminase, lactic dehydrogenase, alkaline phosphatase, or serum bilirubin). The relationship between metabolites and parent cyclosporin was quantitated using the ratio of cyclosporin levels determined by fluorescent polarization immunoassay over levels determined by high-performance liquid chromatography. A cohort of patients with markedly elevated ratios of cyclosporin were identified. When patients' data were reviewed collectively and individually there was a correlation between an elevated ratio and the serum bilirubin (r = 0.41, P less than 0.001). This association could be either due to cyclosporin as a cause of cholestasis or to cholestasis from any cause resulting in metabolite accumulation. Further studies are needed to clarify the role of cyclosporin in hepatic dysfunction and develop early, specific markers for this cyclosporin-associated toxicity.
