Assessment of variation in clinical presentation of visceral leishmaniasis among patients attending the tropical diseases teaching hospital in Sudan

الملخص EN

Background: Visceral leishmaniasis (also known as Kala-azar) is a systemic parasitic infection with many clinical presentations.

The present study assesses the variation in presentations among patients who attended the Tropical Diseases Teaching Hospital (TDTH) in Khartoum, Sudan.

Methods: This analytical cross-sectional, hospital-based study was conducted at the TDTH between November 2019 and September 2020.

Medical records of patients who presented at the TDTH were reviewed using a structured data extraction checklist.

The Chi-square test was used to determine the associations between sociodemographic and clinical presentations of patients.

P-value < 0.05 was considered as statistically significant.

Results: Out of 195 patients, 79.5% were male and 48.2% were <31 years old.

Fever was the main clinical presentation (90.2%) while 53.3% presented with weight loss and 72.3% and 39% presented, respectively, with splenomegaly and hepatomegaly.

HIV was detected in 4.6% of the patients.

RK39 was the main diagnostic test.

We found a significant association between the abdominal distention and the age of the patients (P < 0.05) - age groups 11-20 and 41-50 years were more likely to present with abdominal distention than other age groups.

Conclusion: There is no exact clinical presentation or routine laboratory findings that are pathognomonic for visceral leishmaniasis; therefore, it should be considered in the differential diagnosis of any patient with fever, weight loss, and abdominal distention, and among patients with HIV.
