Resumo: |
Leprosy is an infectious and granulomatous disease caused by Mycobacterium leprae. The aim of this study was to quantify and compare levels of leucocytes and lymphocyte subpopulations (CD3+, CD3+CD4+, CD3+CD8+, CD19+, CD3-CD16+CD56+) in peripheral blood ofpatients with leprosy and healthy controls. Patients were followed at Centro de Dermatologia D. Libânia, Fortaleza-CE, Brasil. Flow cytometry was used to determine numbers of lymphocytes. Statistical analisys was done with GraphPad Prism 5.0 software for windows. P values under 0.05 were considered siginificant.This was an observational case-control study. Fifteen leprosy patients without treatment were evaluated and 29 healthy individuals were included in control group. NK cells (CD3-CD16+CD56+) mean in leprosy patients was 147(±113,4) and in controls was 378,1 (±231,7). Comparisson stablished a p value of 0.0008. B lymphocytes (CD19+) mean in leprosy patients was 233,3 (±85,89) and in controls was 115,3 (±53,01), with p < 0,0001 . No differences were observed in CD3+ T lymphocytes, CD4+ T lymphocytes and CD8+T lymphocytes. This study suggests that NK cells may play a role in innate response to M. leprae. |
