Autoantibodies frequency in children with visceral leishmaniosis

The visceral leishmaniosis (VL), or Calazar, is a chronic severe systemic disease, potentially fatal to humans. Currently, VL is the prototype of a specific immune dysfunction resulting from parasitism of leishmania donovani in macrophages, producing a broad spectrum of clinical and immunological reversible only with specific treatment. Serum Analysis from infected adult patients demonstrated the presence of autoantibodies against cellular and humoral components, and circulating immune complexes.
