THE ROLE OF THROMBOPHILIA IN RECURRENT PREGNANCY LOSS (original) (raw)

Recurrent pregnancy loss thrombophilia

Clinical laboratory

In the last decades we found many data concerning the association between a hypercoagulable state and its causes and adverse pregnancy outcome, in particular recurrent pregnancy loss (RPL). Although 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 such as venous thromboembolism (VTE) during pregnancy. Now, emerging data seem to be available also on the role of active thromboprophylaxis with heparin and pregnancy outcome. This review will be focused on the recent knowledge between thrombophilia, hypercoagulable state, RPL, VTE and future perspectives.

Study of Thrombophilia in Recurrent Pregnancy Loss

The Journal of Obstetrics and Gynecology of India, 2012

Objectives Recently, it has been found that women who have thrombophilia have increased risk of fetal loss. This study was designed to corroborate the association of elevated factor VIII level, protein C and protein S deficiencies, and the presence of LAC in women with recurrent pregnancy loss. Materials and Methods 53 patients with history of two or more pregnancy losses and 47 healthy age-matched subjects with no history of pregnancy loss and who have delivered at least one term infant without any complication were enrolled into the study. Results Thrombophilic defect was present in 64.15 % of patients of study group. Protein S deficiency (50.94 %) was the most common thrombophilic defect observed. Spontaneous abortion (SA), preterm birth (PTB), and intrauterine growth retardation (IUGR) were the most important pregnancy complications observed. The strongest associations of pregnancy complications were observed with protein S deficiency (87.5 %) and with elevated factor VIII (66.66 %) level. Conclusion This study observed strong association of thrombophilia with unexplained recurrent pregnancy loss.

Recurrent Pregnancy Loss and Thrombophilia

Journal of Clinical Medicine Research, 2010

Emerging data seem to be available also on the role of active thromboprophylaxis with heparin and pregnancy outcome. In the last decades we found many data concerning the association between a hypercoagulable state and its causes and adverse pregnancy outcome, in particular recurrent pregnancy loss (RPL). First studies which focused on the association between thrombophilia and RPL underlined the role of reduced clotting inhibitors and RPL, and subsequent studies underlined a pathogenetic role of gene variant associated to hypercoagulable state in the occurrence of RPL. On the other hand, acquired thrombophilic abnormalities as antiphipsholipid syndrome are a well known cause of RPL and should be considered for a screening. These data are relevant because recent studies suggested a role of an extensive thromprophilaxis in women with RPL that should be addressed only in case of known thrombophilia and high risk of venous thromboembolism.

The impact of hereditary thrombophilias in recurrent pregnancy loss

Genetika

Introduction: Recurrent pregnancy loss (RPL) is defined as two or more consecutive pregnancy loss which occurs before the 20th weeks of pregnancies for the last menstrual period. Hereditary cause of thrombophilic gene mutations and polymorphism may play an essential role in RPLs. Material and Method: 291 women with a history of two or more consecutive abortions as a study group and 61 women without the history of miscarriages as a control group were included in a study. In this study we analysed the effects of Factor II Prothrombin mutation ,FV Leiden mutation, MTHFR C677T, MTHFT A1298C, PAI-1, ?-fibrinogen, Factor XIIIA (V34L) and Glycoprotein IIIa (L33P) polymorphisms on RPL by using pyrosequencing. Chi-square and multiple regression analysis were used for statistical analysis. Results: FII prothrombin mutation, FV Leiden mutation, MTHFR C677T, MTHFR A1298C, PAI1 and Beta fibrinogen were found statistically significant in the chi-square test. Heterozygous FV G1691A (OR:8.092, CI: ...

Thrombophilia and Recurrent Pregnancy Loss: The Enigma Continues

Medical science monitor : international medical journal of experimental and clinical research, 2018

BACKGROUND Thrombophilic gene polymorphism is known to be a risk factor for recurrent pregnancy loss (RPL), but few studies have confirmed a possible role of thrombophilic genes polymorphism in RPL risk. This study was conducted to understand the relationship of the mutations of some thrombophilia-associated gene polymorphism (heterozygous/homozygous) with RPL. We compared patients with 2 abortions to patients with 3 or more abortions among Turkish women. MATERIAL AND METHODS In this study, patients previously diagnosed with habitual abortus at Obstetrics and Gynecology outpatient clinics in Turkey between 2012 and 2016 were included. In their peripheral blood, we detected factor V Leiden H1299R, prothrombin G20210A, MTHFR C677T, MTHFR A1298C, PAI-1 4G/5G, and PAI-1 4G/4G gene mutations. RESULTS In this study, we have observed statistically meaningful data (P<0.01) related to the relationship between RPL and thrombophilia-associated gene polymorphisms such as heterozygous factor ...

Prevalence of genetic markers for thrombophilia in recurrent pregnancy loss

2002

BACKGROUND: The genetic predispositions to venous thrombosis such as factor V Leiden (FVL) mutation (Arg 506 Gln), prothrombin (FII) gene mutation (G20210A), and mutation of the methylenetetrahydrofolate reductase (MTHFR) gene (C677T) have been reported to be associated with recurrent pregnancy loss. This paper examines the prevalence of markers for genetic thrombophilias in women with recurrent miscarriage. METHODS: The prevalence of

Positive Correlation Between Platelet Parameters and Genetic Markers of Thrombophilia Panel in Recurrent Pregnancy Loss

2018

Aim: Recurrent pregnancy loss (RPL) defined as 3 or more miscarriages before 20 weeks of gestation by the World Health Organization, and is a common complication during pregnancy, especially for early gestation and affects about 1–5 % of pregnant. In this study, we analyzed mean platelet volume (MPV), platelet count (PLT) values, Factor II g.20210G>A, Factor V Leiden, MTHFR (C677T, A1298C), PAI-1, β-fibrinogen, Factor XIIIA (V34L) and glycoprotein IIIa (L33P) polymorphisms of patients who have RPL history and searched the relationship between genetic thrombophilia markers and platelet parameters in RPL. Methods: A retrospective, clinical trial was performed by reviewing the recurrent pregnancy loss history of 229 patients, and 200 controls. The results of the genetic thrombophilia panel were used to classify the study and control group into low, intermediate and high risk for thrombophilia groups. Results: Factor II g.20210G>A (p=0.035), Factor V Leiden mutations (p=0.027) and...

Approach to Thrombophilia in Pregnancy—A Narrative Review

Medicina

Thrombophilia is a genetic predisposition to hypercoagulable states caused by acquired haemostasis conditions; pregnancy causes the haemostatic system to become hypercoagulable, which grows throughout the pregnancy and peaks around delivery. Genetic testing for thrombophilic gene mutations is evaluated using different methodologies of real-time polymerase chain reaction and DNA microarrays of specific genes. Adapting the general care of the pregnant woman to the particularities caused by thrombophilia is an important component, so screening is preferred to assess the degree of genetic damage that manifests itself as a risk of thrombosis. The major goal of this narrative review was to quantitatively evaluate the literature data on the specific care of pregnant women with thrombophilia that are at risk of developing unplanned miscarriages.
