Summary
The cellular immune response in acute cutaneous leishmaniasis varies, with sporotrichoid lesions showing distinct T cell profiles compared to single or multiple lesions. This suggests a potential difference in the causative parasite species.
Area of Science:
- Immunology
- Dermatology
- Infectious Diseases
Background:
- Cutaneous leishmaniasis presents with diverse clinical patterns.
- Understanding the cellular immune response is crucial for diagnosis and treatment.
Purpose of the Study:
- To evaluate and compare the cellular immune host response in different clinical patterns of acute cutaneous leishmaniasis.
- To investigate immunophenotype cell counts in single, multiple, and sporotrichoid lesions versus normal skin.
Main Methods:
- Cross-sectional, comparative study involving 40 skin biopsies from active lesions.
- Immunophenotyping of cells using monoclonal antibodies.
- Statistical analysis (Kruskal-Wallis Test) of T cell counts (CD3+, CD4+, CD8+, CD57+, CD19+).
Main Results:
- No significant differences in histopathology or infiltrate type between single and multiple lesions.
- Statistically significant differences in total cell count, CD3+, and CD57+ (NK) cells between acute lesions and normal skin.
- Significant differences in CD4+, CD8+, and CD19+ (Plasma cells) counts when comparing sporotrichoid lesions to single and multiple lesions.
Conclusions:
- The sporotrichoid variant of cutaneous leishmaniasis exhibits a distinct cellular immune response.
- This distinct response may indicate infection with a different Leishmania parasite species.
