Abstract:
Visceral leishmaniasis which is known as Kala
azar, or black fever, is a chronic infectious disease
caused by a protozoan parasite of the genus
leishmaniasis, it is transmitted by an insect bite such
as
fly bite and affects all organs in the body.
Therefore, the main objective of this study was to
evaluate the impact of Kala azar on the visceral
organs.
The study was conducted on Gadaref state; the
sample consisted of 144 of Kala azar patients (112
males and 32 females) in the period from October
2010 to February 2011. The data was collected by
using ultrasound scanning technique where the
patients were scanned in order to evaluate the
condition of the liver, gall bladder, spleen and portal
vein using B-mode. The data were collected on the
following variables: texture, echogenecity and size
for all the respective organs. The results of this study
showed that; there is a significant difference
between the liver, spleen, gall bladder and portal
vein from the normal sizes using t-test at p = 0.05
except for gall bladder thickness where the results
were inconclusive. The results also revealed that the
predominant texture was the homogeneous one
95.1% while echogenecity showed that 92.4% of the
cases had hyper echoic appearance
