The parasite frequently causes genital lesions in women and could increase the risk of human immunodeficiency virus (HIV) transmission. This study quantifies the HIV target cells in schistosome-infected female genital mucosa. Cervicovaginal biopsies with and without schistosomiasis were immunostained for quantification of CD4 T lymphocytes (CD3, CD8), macrophages (CD68), and dendritic Langerhans cells (S100 protein). We found significantly higher densities of genital mucosal CD4 T lymphocytes and macrophages surrounding schistosome ova compared with cervicovaginal mucosa without ova ( = 0.034 and = 0.018, respectively). We found no increased density of Langerhans cells ( = 0.25). This study indicates that may significantly increase the density of HIV target cells (CD4 T lymphocytes and macrophages) in the female genitals, creating a beneficial setting for HIV transmission. Further studies are needed to confirm these findings and to evaluate the effect of anti-schistosomal treatment on female genital schistosomiasis.
