Background:
The relationship between Chlamydia trachomatis tubal factor infertility (TFI) and the host's immunoregulatory genes was studied.
Methods:
Cell-mediated immune responses to C. trachomatis and chlamydial heat shock protein (CHSP60) were determined by lymphocyte proliferation assay. HLA-DQ alleles and interleukin-10 (IL-10) promoter polymorphism (-1082 A/G) were analysed in 52 TFI cases and in 61 controls by PCR.
Results:
HLA-DQB1 or DQA1 alleles did not significantly differ between the TFI group and the control group. However, DQA1*0102 and DQB1*0602 alleles together with IL-10 -1082AA genotype were found significantly more frequently in the TFI patients than in the controls (0.18 and 0.02 respectively; P = 0.005). Five (22%) of the 23 patients who had a positive lymphocyte proliferative response to CHSP60 were positive also for IL-10 -1082AA and for the HLA-DQA1*0102 and HLA-DQB1*0602 alleles.
Conclusions:
Our results reveal an association of a cellular immune response to CHSP60, HLA class II alleles and IL-10 promoter genotypes in patients with chlamydial TFI.
