RESUMEN
PROBLEM: Vγ9Vδ2 T cells (γ9δ2) are involved in antibacterial immune responses. The aim of this study was to look for associations between peripheral blood (PB) γ9δ2 T cells and cervix/vaginal Chlamydia trachomatis (Ct) infection in women with recurrent spontaneous abortions (RSA). METHOD OF STUDY: Peripheral blood samples were obtained from 201 RSA women within 10 days after they experienced a new miscarriage. γ9δ2 T cells and their percentage in total γδ T cells were compared between women who had been found and women who had not been found infected with Ct (last 6 months). Fertile women (82) served as control subjects. RESULTS: The difference of mean percentages of γ9δ2 T cells between the abortion and control groups, and the Chlamydia (+) and Chlamydia (-) groups was highly statistically significant (P<.00001). Significant difference was also found between the Chlamydia (+) and Chlamydia (-) group and the control group (ANOVA). CONCLUSION: The measurement of γ9δ2T cells may be useful to suspect possibly undiagnosed chlamydial infection in RSA women.
