OBJECTIVE We present 50 cases of Kawasaki's disease (KD), diagnosed and controlled in our hospital between January 1984 and December 1997. METHODS Fifty patients were reviewed. In forty-six of these cases the onset was complete, according to the Research Committee of MLNS diagnosis criteria and four cases had incomplete onset. RESULTS The ration male/female was 1.9/1. Both fever and oral cavity lesions were present in all cases. In 93.4% desquamation of fingers was observed. The most frequent skin lesion was maculopapular rash. Fourteen patients had atypical onset: adenophlegmon, aseptic meningitis, symptomatic hepatitis, parotiditis, queratopathia punctata and arthritis. Blood analysis showed alterations of high ESR (88% of cases), C-reactive protein (62%), leukocytosis (82%) and thrombocytosis (96%). Fifteen patients were treated with gamma globulin (IGIV), five received a single 2 g/Kg dose and ten received 400 mg/Kg per day during four days. Eight percent of our cases produced cardiovascular complications, none that included coronary aneurysms. CONCLUSIONS After IGIV treatment we observed a shortening of the febrile period and amelioration of clinical symptoms. No deaths were reported.
