Partial regression of advanced cyclosporin-induced gingival hyperplasia after treatment with azithromycin. A case report.

Gingival hyperplasia is a well recognised complication of cyclosporin A therapy. Although its pathogenesis is still debated in several recent reports a second generation macrolide antibiotic-azithromycin induced partial or even complete regression of hyperplasia. We present a patient after kidney transplantation treated with cyclosporin who developed very advanced gigival overgrowth (stage 3+). The patient received a 3-day treatment with azithromycin which was repeated after 3 months. The first course of the drug caused a partial regression of gingival hyperplasia during following months but the repeated treatment did not provide a further regression of the changes.
