Distinct pattern of Th17/Treg cells in pregnant women with a history of unexplained recurrent spontaneous abortion

P-157: TLR5 Gene Expression in Endometrium of Women with Unexplained Recurrent Spontaneous Abortion

Background: Recurrent spontaneous abortion (RSA) is usually defined as three or more consecutive pregnancy losses before 20th week of gestation. Although different factors are considered as etiology of RSA but in some cases, despite of extensive work up, the cause of RSA remains unknown which called unexplained RSA. Immunological factors are suggested as etiological factors of unexplained RSA. ...

Application of Plasma Exchange in Patients with History of Unexplained Recurrent Abortion: A Case Series

Comparing Serum Levels of Th17 and Treg Cytokines in Women with Unexplained Recurrent Spontaneous Abortion and Fertile Women

Background: Increased evidences have shown that unexplained recurrent spontaneous abortion (URSA) is associated with inflammatory responses and breakage of immunological autotolerance. Therefore, the balance between Th17 and Treg cells may elucidate the pathophysiology of URSA. Objective: To investigate the serum concentration of regulatory and inflammatory cytokines associated with Treg and Th...

Seroprevalence of CMV and Rubella in Women with Recurrent Spontaneous Abortion in Comparison with Normal Delivery

Background & Objectives: Recurrent spontaneous abortion occurs by different etiological causes including viral infections. Cytomegalovirus and rubella infections can cause or promote the recurrent fetal loss. Cytomegalovirus is one of the important viral infections which may play a role in recurrent spontaneous abortion. Also, rubella virus infection can induce abortion especially in the first ...

Increase of CD69, CD161 and CD94 on NK Cells in Women with Recurrent Spontaneous Abortion and in Vitro Fertilization Failure

Background: Recurrent spontaneous abortion (RSA) and in vitro fertilization (IVF) failure with unknown causes are the controversial issues that are probably related to the immune system. Objective: To compare circulating NK cells expressing activation and inhibition surface markers between patients with RSA and IVF failure with those of healthy multiparous and successful IVF control women, resp...
