The purpose of the study was to analyze clinical variants of eosinophilic vasculitis (EV). The authors observed 12 EV patients (five men and seven women; mean age 43 +/- 5.7) during a ten-year period. Two of the patients died of ventricular fibrillation due to myocarditis and of mesenterial thrombosis. Clinical variants of EV were diverse. The main syndromes in EV were: predominant lesion of the pulmonary system with polyneuropathy; lesion of the gastrointestinal tract (GIT) with eosinophilia; lesion of the cardiovascular system as well as association with other rheumatologic conditions (rheumatoid arthritis and diffuse eosinophilic fasciitis). The main therapeutic regimens in EV include steroidal therapy in medium to large doses, cyclophosphan intramuscularly, and intensive care–pulse therapy with metipred and plasmapheresis. Analysis of the results of the treatment of these patients demonstrated the efficacy of cyclophosphan administered in doses of approximately 2300 mg per course intramuscularly in combination with prednisolone (more than 40 mg a day), plasmapheresis (more than three sessions per a course), antiaggregants, heparin (more than 18000 units a day) and general hyperbaric oxygenation, as well as pulse therapy with metipred in a dose of 2200 mg per three days as intravenous infusion. The prognosis of EV was most poor in cases of lesion of the cardiovascular system and the GIT.
