Visceral leishmaniasis (VL) or Kala-azar (KA) is a neglected tropical disease caused by protozoan parasite, Leishmania sp. and is fatal, if left untreated. In this study, we measured trace elements (K, Fe, Cu, Zn, Br, Cl, S, Ca, Mn, Cr, Ni, As, Se, Rb and Sr) in the blood of Indian VL patients (32) by particle-induced X-ray emission (PIXE) study. Blood was collected from 36 subjects including healthy controls from Rambagh Kala-azar Hospital, Muzaffarpur, Bihar, India. PIXE experiment was carried out at the Institute of Physics, Bhubaneswar, India and data were analyzed by GUPIXWIN software. We observed first time the association of bromine with the disease. The results showed 48.47 % decrease in Br, 35.16 % decrease in Zn and 29.05 % decrease in Fe in untreated state of the KA patients. In the same group, Cu has been increased by 16.73 %. Cu/Zn ratio has been altered in diseased state. The association of bromine with the disease is reported for the first time and altered levels of trace elements (Br, Cu, Fe and Zn) may come back to normal after completion of the treatment regimen with Amphotericin B. © 2016, Indian Society for Parasitology.
