BACKGROUND Successful pregnancy may depend on a Th2-type cytokine response, whilst, conversely, a poor pregnancy outcome may be associated with an increase in Th1 cytokines and a concomitant decrease in Th2 cytokines. This prospective study was designed to elucidate whether a failure of the cytokine shift pre-dated miscarriage and was therefore likely to be an aetiological factor in recurrent p...
The balance between coagulation and fibrinolysis is an essential part in early pregnancy. Mutations in methylenetetrahydrofolate reductase (MTHFR) gene lead to decreased activity of the enzyme and hyperhomocysteinemia, which then induces platelet aggregation by promoting endothelial oxidative damage, possibly resulting in adverse effect on maintenance of pregnancy. We investigated the role of M...
In recent decades, the association between a hypercoagulable state and its causes and adverse pregnancy outcome, in particular recurrent pregnancy loss (RPL) has been studied extensively. Although the first studies were focused only on the association between thrombophilia and RPL, subsequent studies underlined also a potential role of antithrombotic treatment to prevent vascular complication s...
Recurrent pregnancy loss (RPL) is a frequently occurring disease, which is classified as idiopathic in more than 50% of cases. THBD, the endothelial cell receptor for thrombin, has been associated with distinct biological processes and considered a coherent RPL-related candidate gene. In the present study, we have sequenced the complete coding region of THBD in 262 patients affected by RPL. Bio...
Background & aim: Recurrent pregnancy loss is defined as loosing at least 2 pregnancies before 20th weeks of gestation. Besides all the known causative factors, in about half of the cases, the causing factor, remains unknown. In recent years, some studies have shown the role of candidate genes polymorphisms in RPL. CDH1 is one of these candidate genes that plays critical role in embryo implanta...
BACKGROUND Some evidence has shown a relationship between human cytomegalovirus (CMV) infection and pregnancy loss. However, whether recurrent or latent CMV infection or altered immune response to CMV is related to recurrent pregnancy loss (RPL) is unclear. We evaluated CMV infection and avidity of antibodies to CMV in women with RPL. MATERIALS AND METHODS This case-control study was conducte...
BACKGROUND Recurrent fetal loss (RPL) is one of the most common cause of sterility. Several studies identified thrombophilia as the principal cause of recurrent pregnancy loss. However, reported studies often do not evaluate other causes of miscarriages in their inclusion and exclusion criteria. So the aim of our study was to investigate the role of inherited thrombophilia in patients with RPL ...
Comparative Cytogenetic Analysis of Spontaneous Abortions in Recurrent and Sporadic Pregnancy Losses
Background: The majority of miscarriages are sporadic; however, 1–5% of couples experience recurrent pregnancy loss (RPL). Approximately 50–60% of miscarriages result from chromosomal abnormalities. Currently, there are conflicting reports regarding the rates of chromosomal abnormalities between recurrent and sporadic pregnancy losses. Methods: A retrospective comparative cytogenetic analysis o...
BACKGROUND Miscarriage is a common phenomenon complicating more than half of pregnancies. Recurrent Pregnancy Loss (RPL) is defined as three or more pregnancies lost before the twentieth week of gestation. It is believed that abnormality in maternal immune reaction to fetus and sharing of HLA antigens might be associated with RPL. OBJECTIVE To investigate the effect of HLA-DRB1 sharing betwee...
background: recurrent pregnancy loss (rpl) defined by two or more failed pregnancies before 20 weeks of gestation. several factors play a role in rpl including thrombophilic conditions which can be influenced by gene polymorphisms. plasminogen activator inhibitor-1 (pai-1) and angiotensin converting enzyme (ace) genes are closely related to fibrinolytic process, embryonic development and pregna...
