The Parasitemia has Contributed to the Severity of Cases of Visceral Leishmaniasis.

Visceral leishmaniasis (VL) occurs due to the evolution, virulence, and adaptation of , vector biology, host immune system evasion, and reservoir hosts. Parasitemia can be involved as a warning regarding the clinical severity of VL The present study aims to evaluate the relationship between parasitemia and the prognosis of individuals with VL. Blood and bone marrow samples from individuals with VL were analyzed to identify parasite and quantify or measure parasite burden.

Modulation in the expression of type 1 (CR1/CD35) and type 3 (CR3/CD11b) complement receptors on leukocytes from patients with Visceral leishmaniasis.

Visceral leishmaniasis (VL) is an anthropozoonosis endemic in Brazil. We included 20 patients with confirmed diagnosis of VL and 20 healthy individuals to evaluate the expression levels of complement receptor 1 (CR1)/CD35 and CR3/CD11b on leukocytes in the peripheral blood and determine their correlation with the clinical state of patients. CR1/CD35 expression increased on CD11bCD35granulocytes of patients, while CR1/CD35 and CR3/CD11b expression levels increased on CD14CD11bCD35 monocytes.
