Abstract

FERREIRA, Maurício Domingues et al. Cellular immunodeficiency related to chronic dermatophytosis in a patient with Schistosoma mansoni infection: can schistosomiasis induce immunodeficiency?. Rev. Soc. Bras. Med. Trop. [online]. 2017, vol.50, n.1, pp.141-144. ISSN 0037-8682.  http://dx.doi.org/10.1590/0037-8682-0107-2016.

Here, we describe a case of hepatosplenic schistosomiasis that progressed to widespread persistent dermatophytosis. Significant T and B lymphocytopenia was confirmed. T-cell deficit is associated with increased susceptibility to fungal infections of skin and mucous membranes. The accumulation of a large amount of blood cells in the spleen could have played a crucial role in the development of lymphocytopenia in the present case. Alternatively, the schistosomiasis-induced increase in prostaglandin E2 levels could have inhibited the production of interferon-γ, a cytokine fundamental to fungal resistance. This case shows the potential of hepatosplenic schistosomiasis to impair the immune response.

Keywords : Schistosomiasis; Immunodeficiency; Chronic dermatophytosis.
