RESUMEN
We studied two groups of pregnant women: 30 asthmatic and 20 non- asthmatic ones (as control), within a eleven-month period. We filled clinical data with inclusion and exclusion criteria for our investigation. We performed tests for determination of E, G, A and M immunoglobulins; and spontaneous rosettes tests and lymphocytic CD4+ and CD8+ subpopulations, as well. We found high IgE levels in the asthmatic pregnant women, in each pregnancy quarter. In relation to IgG and IgA we found a diminishing tendency from the beginning to the end of pregnancy, with statistical meaning, in beth groups of women. We didn't get significant variations for IgM, spontaneous rosettes and lymphocytic CD4+ and CD8+ subpopulations levels, in any of the two pregnant groups, in any of three pregnancy quarters, in our investigation.
