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,
