in addition to ultrasonographic monitoring of folliculogenesis, urinary luteinizing hormone testing, luteal phase endometrial biopsy, serum antiphospholipid antibodies, etc., immunologic tests are recently being used to evaluate reproductive disorders. in this study, sharing of hla-a, b, c and dr antigens and the presence of antipaternal cytotoxic antibody (apca) was assessed using microcytotox...

conclusions antipospholipid antibodies based on number of abortions and gestational age of abortions were increased. mean antipospholipid and anticardiolipin antibodies in all patients remained in high level just in first 5 years post abortion and then began to fall. results mean age of participants was 24-39 years old. the average rate of antiphospolipid antibodies in patients with normal anti...

Spontaneous abortion is the most common complication of pregnancy. Immune activation and the subsequent inflammation-induced tissue injury are often observed at the maternal-fetal interface as the final pathological assault in recurrent spontaneous abortion. However, the precise mechanisms responsible for spontaneous abortion involving inflammation are not fully understood. Chemokine CCL28 and ...

Massive chronic intervillositis (MCI) is an unusual placental lesion associated with poor fetal growth and adverse pregnancy outcome; it has not previously been associated with spontaneous abortion or recurrent pregnancy loss. This article reports a patient who had 10 spontaneous abortions with repetitious massive chronic intervillositis documented in four of five gestations spanning all three ...

Recurrent spontaneous abortions (RSA) are estimated to affect 0.5-1% of couples trying to have a child. The causes of RSA are unknown in the majority of cases. This study aimed to determine whether homozygous mutations in the AMN gene in a fetus cause spontaneous abortions in humans, as they are known to cause spontaneous abortions in mice. The study was conducted by screening 40 couples and 5 ...

Recurrent spontaneous abortion (RSA) is reported to be associated with immune imbalance at the maternal-fetal interface. Immune cells in the decidual tissue are involved in maintaining immune tolerance during pregnancy; however, whether natural killer (NK) and T cells are altered in unexplained RSA (URSA) remains unknown. In this study, we compared the number and percentage of CD56(+) NK cells,...

Recurrent spontaneous miscarriage (RSM), defined as ≥2 clinically detectable pregnancy losses before 20 weeks of gestation with the same partner. Many studies have been suggested abnormal natural killer (NK) cell activity can be a high chance division linked with RSM. Aberrant expression of angiogenic cytokines during implantation window in women with RSA is one of the key factors that adversel...

Background: The maximum probability of conceiving during a menstrual cycle is only about 40%. One third of conceptions do not result in the delivery of a baby recurrent miscarriage, defined as the loss of 3 or more pregnancies before 20 weeks post-menstruation that affects 1% of all women. Approximately 20 percent of pregnant women will have some bleeding before 20 weeks’ gestation, and roughly...

OBJECTIVE A case-control study was undertaken to assess the association between an estrogen receptor gene variant and the risk of recurrent spontaneous abortions. STUDY DESIGN The frequency of the estrogen receptor gene variant in blood lymphocyte deoxyribonucleic acid and other selected maternal characteristics was compared among 60 primary recurrent aborters, 61 secondary recurrent aborters...

BACKGROUND Different studies show that chromosomal balance translocation in the parents can cause recurrent spontaneous abortions. Incidence of chromosomal translocation abnormalities in couples with repeated abortions is from 0% to 31%. OBJECTIVE The purpose of this research was studying the presence or absence of chromosomal abnormalities and heteromorphism in couples with recurrent abortio...
