Positivity, diagnosis and treatment follow-up of cutaneous leishmaniasis in war-affected areas of Bajaur, Pakistan.

This study was conducted to explore the frequency of positivity of cutaneous leishmaniasis (CL) in the tribal district Bajaur located near the Pak-Afghan border. The present study was conducted at the Leishmaniasis Center of Headquarter Hospital Khar District Bajaur, Pakistan. In total, 646 patients were recruited and included in the study after ethical approval and consent from the patients. CL was confirmed by taking blood samples from the sides of the lesion and observing them under a microscope using Giemsa staining. Information about demographic factors was collected from the study participants with a questionnaire and analyzed by SPSS. It was found that 73.8% of suspected patients were positive and 26.2% were negative for CL. There were 51.9% male and 48.1% female patients. The most frequently affected site was the face (42.6%), and most of the patients (85.8%) had only one lesion. The positivity of CL was higher among those under age 15 years. The area of most positivity, with 45.2% of the cases, was Tehsil Mamund. Most of the patients (46.6%) lived in stone houses, with 98.6% of patients having domestic animals in their houses. Approximately 198 patients were treated with intramuscular and intralesional injections of meglumine antimoniate, and their weekly follow-up revealed that 48% of patients recovered, while the remaining patients left the course of treatment at different stages of therapy. The positivity of CL is high in this area and is confirmed by the detection of Leishmania amastigotes in the blood collected from their lesions. Socioeconomic factors are the main underlying causes of the rapid spread of this disease and meglumine antimoniate is an effective drug.
