Abstract

Peripheral leucocyte migration inhibition (LMI) with Trypanosoma cruzi-specific antigens, measured as a migration index (MI), was studied in chronic Chagas' disease patients. The MI of untreated patients with polymerized antigens from culture forms (epimastigotes) of T. cruzi was significantly lower than that of controls. In contrast, when chronic Chagas' patients were treated with nifurtimox, 10 mg/kg/day for 2 months, the MI was not different from control values. Treated and untreated patients had normal T- and B-lymphocyte markers, measured by the ability to form rosettes either with sheep erythrocytes (E-RFC) or with sheep erythrocytes--antibody--complement (EAC-RFC). In addition, the number of lymphocytes bearing surface membrane Ig (SMIg) was the same as that of controls. Non-specific functional assays, such as PHA-induced blastogenesis and antibody-dependent cell-mediated cytotoxicity (ADCC) to sensitized chicken erythrocytes were also normal, both in treated and untreated patients. Thus, nifurtimox produced a particularly effect on cell-mediated immunity, specially detectable using LMI.
