Abstract

The frequencies of blood groups, Rh and HLA antigens were studied in a series of patients with paracoccidioidomycosis as well as in control subjects. Statistical analysis of the results showed that only 2 antigens (HLA-A9 and HLA-B13) had a significantly increased frequency among patients with paracoccidioidomycosis compared with healthy controls. Among patients with paracoccidioidomycosis antigen HLA-A9 was significantly more prevalent in progressive pulmonary forms of the disease than in patients with extra pulmonary involvement. These observations suggest that HLA-A9 may influence susceptibility to the mycosis as well as its course.

Sumario

Se estudió la frecuencia de los grupos sanguíneos y de algunos antígenos de histocompatibilidad en 41 pacientes con paracoccidioidomicosis y en un grupo control. Al comparar los pacientes con los controles, el análisis estadístico demostró aumento significativo en 2 de los antígenos estudiados, el HLA-A9 y el HLA-B13. Al determinar la relación de tales antigenos con el tipo de manifestación clínica se observó que un número significante de pacientes con HLA-A9 exhibían la forma progresiva pulmonar de la paracoccidioidomicosis. Estas observaciones sugieren que la presencia de HLA-A9 puede influir sobre la susceptibilidad a la micosis e inclusive, estar relacionada con el curso de la misma.
