title: [Neuropathy in long term treatment with metronidazole (author's transl)].
abstract: Two patients developed a sensory neuropathy while under treatment with Metronidazole for Crohn's disease. Recovery took place within a few months after drug withdrawal but was still incomplete in one patient one year after cessation of Metronidazole intake. The incidence of neuropathy appears to be high in long term use of this drug. The morphological study of a sural nerve biopsy showed a severe loss of myelinated fibers (1 800 par mm2). Quantitative teased fibers preparation showed that 56 per cent of the fibers were undergoing wallerian degenerations ; segmental demyelination with subsequent remyelination was found in 4 per cent of the fibers and seem to be secondary to axonal involvement.
