introduction: one factor known to cause thrombophilia in women with unexplained recurrent spontaneous abortion (rsa) is c677t polymorphism of methylenetetrahydrofolate reductase gene. this study aimed to determine the association between rsa and mthfr c677t polymorphism in iranian patients. methods: in this case-control study, 30 patients with previous history of two or more consecutive unexpla...

Recurrent spontaneous abortion (RSA) may have immunological etiology. The aim of this study was to assess the efficacy of a high dose intravenous immunoglobulin (HIVIg) therapy, in which 20 g of intact type immunoglobulin was infused daily for 5 days during early gestation, for women who had a history of four or more consecutive spontaneous abortions of unexplained etiology. A total of 60 pregn...

Introduction: One factor known to cause thrombophilia in women with unexplained recurrent spontaneous abortion (RSA) is C677T polymorphism of methylenetetrahydrofolate reductase gene. This study aimed to determine the association between RSA and MTHFR C677T polymorphism in Iranian patients. Methods: In this case-control study, 30 patients with previous history of two or more consecutive unexpla...

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...

BACKGROUND In normal pregnancy, predominant type 2 cytokines help maintain pregnancy, and a T-helper (Th)1 type response is associated with unexplained recurrent spontaneous abortion (RSA). However, Th2 and T-cytotoxic (Tc)2 cells have not been localized at the implantation site in RSA. METHODS Twenty-one cases with RSA were classified into RSA with normal chromosomal content (RSA-N, n = 10) ...

background:   objective: in this study we performed linkage analysis on a large x linked rsa pedigree to find a novel susceptibility locus for rsa.   materials and methods: a linkage scan using 11 microsatellites was performed in 27 members of a large pedigree of hereditary x-linked rsa. two point parametric linkage was performed using superlink v 1.6 program. results: evidence of linkage was o...

Background Recurrent spontaneous abortion (RSA) is a complication in pregnancy that results into fetus rejection by mother and several factors such as anatomical, genetic and immunological problems can be its etiologic causes. Paternal lymphocyte therapy as an immunotherapy for these patients has been more evaluated. The purpose of lymphocyte therapy is stimulation of the mother immune system t...

Background Congenital toxoplasmosis is an important cause of spontaneous abortion worldwide. However, there is limited information on detection and genotypic characterization of T. gondii in women with recurrent spontaneous abortion (RSA). The aim of this study is molecular detection and genotypic characterization of T. gondii in formalin-fixed, paraffin-embedded fetoplacental tissues (FFPTs) o...

CONTEXT AND OBJECTIVE Recurrent spontaneous abortion (RSA) is defined as three or more consecutive pregnancy losses before 20 weeks and is associated with several etiological factors related to genetics, anatomy, hormones, infections and immunology, for example. Many cases of RSA remain unclear. New factors or their associations may influence gestational results. The aim was to identify possibl...
