Estudo das alterações cardíacas em crianças com SIDA em relação à terapêutica com anti-retrovirais. Estudo prospectivo de 47 casos / Study of the cardiac alterations in HIV-infected children consequent to the antiretroviral therapy. Prospective study of 47 cases

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 percent) 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 percent) 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

Cardite reumática tratada com altas doses de metilprednisolona venosa (pulsoterapia): resultados em 70 crianças durante 12 anos / Rheumatic carditis treated with high doses of pulsetherapy methylprednisolone: results in 70 children over 12 years

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 rulling out infections and stronglyoidiasis, 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 per cent) were in their 1st attack: 2 series of pulsetherapy were used in 10 (25 per cent), 3 in 9 (23 per cent) and 4 in 21 (52 per cent). In Group 2, 14 cases (77 per cent) were in their 1st attack: 2 series were used in 7 (39 per cent), 4 in 9 (50 per cent) and 5 in 2 (11 per cent). The echocardiogram showed a flail mitral valve in 12 (66 per cent) 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 per cent). 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.
