Evaluation of human chaperonin 10 and high-sensitivity C-reactive protein levels of infertile women who underwent ovulation induction and intra-uterine insemination

Abstract

Introduction: The implantation of embryo is one of the crucial steps of a successful pregnancy. The foetus should be protected from maternal immune system, for the appropriate implantation and modification in maternal immunity is crucial. We investigated high-sensitivity C-reactive protein (hs CRP), which is an indicator of low-grade inflammation and Cp10 that has immunosuppressant and growth-promoting capabilities at embryo levels in ovulation induction and intra-uterine insemination (IUI) applied in infertile women. The ovulation induction was maintained by clomiphene citrate or gonadotropins for 42 infertile patients. After successful ovulation induction, IUI was carried out. The blood samples were taken 2 and 8 days after IUI to evaluate Cp10 and hs CRP levels. The pregnant and non-pregnant groups' results were analyzed. The Cp10 levels 8 days after IUI were higher in pregnant group, whereas there was no difference for the 2 days after levels between pregnant and non-pregnant group. The hs CRP levels were similar for both 2nd and 8th days when we compared pregnant and non-pregnant groups. The Cp10 levels increased from day 2 to day 8 in pregnant group. In contrast, the Cp10 levels decreased in non-pregnant group. The change in hs CRP levels from day 2 to day 8 was not significant in pregnant and non-pregnant groups. The Cp10 levels were higher in early phases of fertilisation and elevated through the preceding days of conception in pregnant patients, while it decreased in non-pregnant patients with failed cycles.
