OBJECTIVE: Detect of cardiac alterations in children with AIDS and compare their evolution with the administration of only one anti-retroviral and the recent cases who received drugs in combination. METHODS: We prospectively studied 47 children in 3 groups: group 1, 20 cases treated only with zidovudine; group 2, 10 patients treated initially with zidovudine and later with a combination of drugs and in group 3, 17 patients, who receiced two or three since the beginning. In all patients it was done chest X-ray, EKG and echocardiography every 6 months and after death complete pathological study. RESULTS: Among the 45 patients cases 26 (57%) were index cases. Malnutrition, diarrhea tachycardia, signs of congestive heart failure, pericardial effusion, abnormal ventricular repolarization and arrhythmias were more frequent in group 1. Echocardiographic abnormalities were present in 10 (50%) children of group 1. They were less frequent in the others two groups. In regard to the outcome in group 1, two patients had worsening of sings of cardiomyopaty and 4 died. Cardiac dysfunction in all cases of group 2 and 3 improved with the medication. CONCLUSION:- The children who received combination and their cardiac alterations had more favorable outcome than those who received only one drug.

OBJECTIVE - To evaluate the cardiac abnormalities and their evolution during the course of the acquired immunodeficiency syndrome, as well as to correlate clinical and pathological data. METHODS - Twenty-one patients, admitted to the hospital with the diagnosis of acquired immunodeficiency syndrome, were prospectively studied and followed until their death. Age ranged from 19 to 42 years (17 males). ECG and echocardiogram were also obtained every six months. After death, macro- and microscopic examinations were also performed. RESULTS - The most frequent causes of referral to the hospital were: diarrhea or repeated pneumonias, tuberculosis, toxoplasmosis or Kaposi sarcoma. The most frequent findings were acute or chronic pericarditis (42%) and dilated cardiomyopathy (19%). Four patients died of cardiac problems: infective endocarditis, pericarditis with pericardial effusion, bacterial myocarditis and infection by Toxoplasma gondii. CONCLUSION - Severe cardiac abnormalities were the cause of death in some patients. In the majority of the patients, a good correlation existed between clinical and anatomical-pathological data. Cardiac evaluation was important to detect early manifestations and treat them accordingly, even in asymptomatic patients.

PURPOSE: To report the result of patients treated with IV methylprednisolone divided into three groups and compare their follow-up during the last 12 years. METHODS: Seventy children with active rheumatic carditis (76 episodes) in heart failure Class III and IV (NYHA) were studied. The diagnosis was based on modified Jones' criteria. After ruling out infections and strongyloidiasis, treatment with IV methylprednisolone bolus was started three times a week until the laboratory tests became negative. Patients were divided into 3 groups, according to the time of hospital admittance: Groups 1, 2 and 3, comprising of 40, 18 and 12 children, respectively. RESULTS: Eighteen children in Group 1 (45%) were in their 1st attack: 2 series of pulsetherapy were used in 10 (25%), 3 in 9 (23%) and 4 in 21 (52%). In Group 2, 14 cases (77%) were in their 1st attack: 2 series were used in 7 (39%), 4 in 9 (50%) and 5 in 2 (11%). The echocardiogram showed a flail mitral valve in 12 (66%) of these patients (1 death occurred after mitral valvoplasty). In Group 3, 6 patients needed 5 or more series of pulsetherapy and a flail mitral valve was present in 5 (41%). One child underwent mitral valve replacement while still in the active phase, after 8 series of pulsetherapy, and another died. The number of patients who needed 5 or more series was significantly higher in Group 3. CONCLUSION: There were variations in the presentation and evolution of the cases during these 12 year. The established pulsetherapy protocol continues to be useful to treat severe cases.
