ABSTRACT
Epidemiological, clinical, diagnostic, and therapeutic data from children who were born to mothers infected with T. cruzi who came to our hospital are presented. In addition, we exhibit the preliminary results of a technique that detects the anti F2/3 antibodies these would be able to confirm the cure earlier than conventional serology. We also show the results of PCR diagnosis. Most of the mothers (76,1%) resided in Argentina, the rest were from Bolivia and Paraguay The median average age at diagnosis of the patients was 8,5 months (range 15 days-10 years). Out of 168 children, 64,98% were asymptomatic at diagnosis. The diagnosis criteria were T. cruzi observation by microhematocrit technique in patients less than 7 month old. Two reactive serological tests in patients older than 8 months. A nifurtimox dose used in these patients was 10-13 mg/kg/d during 60 days. Although 31% presented side effects, none of them had to be dropped from the treatment. Cure criteria was conventional serology negativization. Of the patient population, we cured 87,2% of them, 98% of those under 3 years, and 100% of those who received treatment before age 8 months. We compared the time of negativization between conventional serology and anti F2/3 in 21 children. The latter were very useful to demonstrate (p>0,001) the success of the treatment, in those that started treatment after 8 months of age. PCR testing of a group of all patients, showed a diagnostic sensibility of 80,3% and a specificity of 97,8%.
