Evaluation of prajmalium-induced cholestasis by immunologic tests.

Cholestatic jaundice developed in four patients after the administration of prajmalium bitartrate. The clinical, histologic, ultrastructural, and immunologic findings were determined. In all patients, the clinical and morphologic features indicated idiosyncrasy. Two antibodies distributed in a granular pattern along the bile canaliculi were detected by immunofluorescence in all patients. In one patient, autoimmune markers were found in the serum, and in two instances, the migration-inhibition factor assay against the offending drug was found to be positive. The data support the concept that immunologic processes may participate in the production of the cholestatic syndrome.

Experience with immunological tests in drug-induced hepatitis.

Nine patients are reported who developed hepatic injury following the administration of therapeutic agents. The drugs incriminated were prajmalium bitartrate (4 patients), quinidine (3 patients), procainamide and nifedipine (one patient each). In all patients the clinical features indicated an allergic process, which in three cases was substantiated by positive response to reexposure. The detection of immunologic processes in our patients by various in vitro methods supports the assumption that immune mechanisms may be involved in the production of drug-induced hepatic disease and confirm allergy.

Cholestatic jaundice: an immune response to prajmalium bitartrate.

Cholestatic jaundice associated with chills, pruritus and blood eosinophilia developed in a patient who received prajmalium bitartrate therapy for ventricular arrhythmia following acute myocardial infarction. Discontinuation of the drug resulted in a spontaneous improvement in the clinical and biochemical findings. Challenge by prajmalium bitartrate caused rapid reappearance of the clinical and biochemical features. In immunological studies, deposits of IgG and IgA were detected at the bile canaliculi by fluorescent staining, and the patient's lymphocytes produced macrophage migration inhibition after in vitro incubation with prajmalium bitartrate. Thus, laboratory results support the assumption of an allergic mechanism.
