Abstract
OBJECTIVES
This study sought to determine the endemic Leishmania species, the clinical features of cutaneous leishmaniasis (CL) in the Central Rift Valley in Kenya and to give an account on unresponsiveness to treatment in the region.
METHODS
Participants were clinically identified and grouped into untreated, classical and recidivate based on clinical manifestation and clinical data. Leishmaniasis recidivans lesions were scaly hyperemic papules that appeared before the classic lesion had healed or after healing. The demographics and socio-economic data were recorded and lesion scraping samples screened through microscopy and Internal Transcribed Spacer 1-PCR. Leishmania species were identified using Restriction Fragment Length Polymorphism.
RESULTS
A total of 52 participants were sampled, of which, 44.2% of the cases were recidivate and L. tropica the only species identified. All patients had been treated using sodium stibogluconate (SSG) which is the recommended first-line drug in Kenya. 60% of the patients experienced prolonged exposure to the drug (>30 days).
CONCLUSION
L. tropica is the endemic Leishmania species for CL leading to classical and leishmaniasis recidivans. Treatment of CL in the area is not effective hence, alternative measures/therapy should be considered to cope with the unresponsiveness.
