Cutaneous Leishmaniasis with HIV

Area of Science:

• Medical Parasitology
• Infectious Diseases
• Dermatology

Background:

• Cutaneous Leishmaniasis (CL) is a significant vector-borne parasitic disease prevalent in endemic regions like Balochistan, Pakistan.
• Human Immunodeficiency Virus (HIV) infection can lead to immunocompromise, potentially altering the clinical presentation and treatment response of CL.
• Atypical and reactivated CL lesions are observed in HIV-coinfected patients, often exhibiting poor response to standard therapies and frequent relapses.

Observation:

• This report details three cases of localized and disseminated CL caused by Leishmania tropica in Balochistan.
• Initial clinical presentations, including weight loss and fever, prompted HIV testing in these patients.
• Despite the endemic nature of CL, HIV infection was not initially suspected but confirmed via Enzyme-linked Immunosorbent Assay (ELISA).

Findings:

• The reported CL cases, though atypical, demonstrated a positive response to meglumine antimoniate treatment.
• HIV-positive status was diagnosed in patients presenting with symptoms suggestive of CL, indicating a potential link.
• Leishmania tropica was identified as the causative agent in these specific CL cases.

Implications:

• Cutaneous Leishmaniasis is increasingly recognized as an opportunistic infection in the context of HIV/AIDS.
• CL may serve as an initial clinical manifestation of HIV infection, particularly in endemic areas.
• Early diagnosis and integrated management of CL and HIV are crucial for improving patient outcomes in endemic regions.
