Abstract

Background: Immune responses during pregnancy show a distinct shift towards Th2-type reactions occurs, especially at the feto-maternal interface. CD30 has been described as being preferentially expressed, and released, by human T cells producing the Th2-type cytokines.Objective: To determine the level of soluble CD30 (sCD30) in serum and in the trophoblasts of patients with recurrent spontaneous abortion (RSA).Materials and methods: A total of sixty one women attending the Obstetrics department in al- kadhimiya hospital, age range from (23.9 - 28.5years), were enrolled in the current study and were further classified into three categories: Group A: 35 women included cases with recurrent spontaneous abortion, group B: 16 women included non- recurrent spontaneous abortion (non-RSA): group C: 10 women was Control (successful pregnancy). From each subject blood sample and placental tissues were collected and serum was seperated for the estimation of soluble CD30 (sCD 30) levels using ELISA method and trophoblasts tissues (an image for the local microenvironment) were screened to determine the levels of CD30 using immunohistochemistry. Results: Trophoblast expression of CD30 and sCD30, showed a highly significant increased values for both patients groups (p<0.001) when compared with control group.Conclusion: It is likely that there may be an association between normal pregnancy and CD30 density on the cell surface. Key words: recurrent spontaneous abortion, CD30, mmunohistochemistry, ELISA
