L'interféron γ transforme le pronostic des patients atteints de Leishmaniose chimiorésistante.
Résumé
T lymphocytes from patients with visceral leishmaniasis treated in vitro with leishmania antigens are unable to proliferate and to produce γ interferon. These patients have negative specific skin tests. Opposite results are obtained in patients with another clinical form of the disease named mucocutaneous leishmaniasis, in which both tests are positive. Nevertheless, patients with visceral leishmaniasis or mucocutaneous leishmaniasis, refractory to chemotherapy (antimonium complex), were cured when antimonium in combination with gamma interferon, in spite of different immunological profiles. Different interpretative hypotheses of the reversion of chemoresistance induced by γ interferon are discussed.
