Defective phagocytosis in chronic trichophytosis.
Chronic trichophytosis as a primary clinical entity (primary chronic trichophytosis, PCT) is increasingly encountered in the literature. Its prevalent cause in Croatia is the anthropophilic form of Trichophyton interdigitale. Chronicity of the disease may result from immunological defects of the patients. Thus, in 62 patients with PCT: skin testing, enumeration of T- and B-lymphocytes in the peripheral blood, quantitation of immunoglobulin classes, and phagocytosis (random mobility, ingestion, digestion and extracellular killing) by peripheral blood leukocytes was tested. The findings were compared to those in healthy persons. Defective phagocytosis (random mobility, ingestion and digestion) was found in patients with PCT (P < 0.001). All the other results were within the control range. Therefore, PCT seems to be associated with defective phagocytosis of peripheral blood leukocytes in affected persons.
