Epidemiology, clinical characteristics, and treatment outcomes of leishmaniasis in Qatar: A retrospective study.

Background: Leishmaniasis is an emerging tropical infectious disease in Qatar. It is caused by the protozoan parasite of the Leishmania genus, which is endemic in many regions of the world, including the Middle East. In Qatar, there is limited data about this disease, which is hindering the efficient planning and implementation of disease prevention and control measures. Therefore, to address this knowledge gap, we conducted a retrospective study to gather information on the prevalence, clinical characteristics, as well as outcomes of leishmaniasis treatment. The primary objective of this study is to provide a comprehensive analysis of leishmaniasis cases in Qatar over seven years (2016-2022). The findings of this study offer valuable insights that can guide the development of a national registry and treatment program for leishmaniasis in Qatar.

Methods: Using a retrospective cross-sectional study design, clinical and epidemiological data of all documented cases of leishmaniasis in Qatar between 2016 and 2022 were collected from electronic medical records at Hamad Medical Corporation (HMC).

Results: A total of sixty-eight cases of leishmaniasis were detected in Qatar between 2016 and 2022. Males were predominant (69.12%) with a median age of 33 years. Our study revealed a higher incidence of leishmaniasis among individuals of Syrian nationality, followed by Pakistani and Sudanese, thus promoting further investigation into the underlying factors contributing to this health disparity. Our findings revealed important epidemiological trends, highlighted key clinical characteristics, identified risk factors associated with susceptibility to leishmaniasis, and reported treatment outcomes.

Conclusion: This retrospective study presents the first comprehensive analysis of leishmaniasis in Qatar, shedding light on the epidemiology, clinical characteristics, and treatment outcomes of the disease. The data generated from this study can serve as a guide for authorities in establishing a national registry and treatment program for leishmaniasis in Qatar. Implementing these measures will contribute to the effective management and control of leishmaniasis, ultimately improving patient outcomes and public health in the country.
