Vitamin A is considered an anti-infectious disease vitamin, and its
deficiency is associated with severe infections such as in measles. In
developing countries the low concentrations of vitamin A are a public
health problem. The aim of this study is to describe serum vitamin
A concentrations among children with visceral leishmaniasis (VL). Blood
sample was collected from 22 children with VL, and stored in a freezer,
9 siblings, with no clinical signs of the VL patients had their blood
collected for a control group. Samples were assayed by high performance
liquid chromatography. The median vitamin A concentration in the LV group
was 21.38 microg/100ml and in the control group it was 31.39 microg/100.
The mean in the LV was statistically lower than in the control group,
using Student's t test, p<0.01.
