The EVAPIL scale, a new tool to assess tolerance of oral contraceptives.

BACKGROUND: The EVAPIL scale is a self-questionnaire aimed to assess tolerability of oral contraceptives (OC). METHODS: For initial development: a list of questions addressing the more frequent or more unpleasant minor side effects of OC was developed by a group of gynecologists and submitted to several sets of OC users. A final version with 14 questions was issued with scoring rules. For validation, the EVAPIL scale was submitted to 3502 women who were OC users for at least 6 months to evaluate internal consistency and factorial structure. Test-retest reproducibility was studied 30 days apart in 53 other OC users. RESULTS: Internal consistency was good (Cronbach's alpha .71) without redundant questions. Principal components analysis with Varimax rotation was used to summarise information given by the 14 questions in a smaller number of multivariate dimensions. Dimension 1 explained 22% of the total variance, strongly correlated with all symptoms except oily skin, acne and cycle control. Dimension 2 accounted for 10% of the total variance and was correlated with oily skin and acne. Dimensions 3 and 4 were better correlated with cycle control. Reproducibility was excellent (intraclass correlation 0.88). The EVAPIL scale was found easy to use and took no more than 5 min to complete. CONCLUSION: The EVAPIL scale demonstrated interesting psychometric properties to evaluate the tolerability of OCs in OC users. Further research is needed to address sensitivity to change and usefulness in new OC users.

Low-molecular-weight heparin versus low-dose aspirin in women with one fetal loss and a constitutional thrombophilic disorder.

The prospective evaluation of the effect of thromboprophylaxis in women with one unexplained pregnancy loss from the 10th week of amenorrhea was performed. A total of 160 patients with heterozygous factor V Leiden mutation, prothrombin G20210A mutation, or protein S deficiency were given 5 mg folic acid daily before conception, to be continued during pregnancy, and low-dose aspirin 100 mg daily or low-molecular-weight heparin enoxaparin 40 mg was taken from the 8th week. Twenty-three of the 80 patients treated with low-dose aspirin and 69 of the 80 patients treated with enoxaparin had a healthy live birth (odds ratio [OR], 15.5; 95% confidence interval [CI], 7-34, P <.0001). Enoxaparin was superior to low-dose aspirin in each subgroup defined according to the underlying constitutional thrombophilic disorder. An associated protein Z deficiency and/or positive antiprotein Z antibodies were associated with poorer outcomes. The neonate weight was higher in the women successfully treated with enoxaparin, and neonates small for gestational age were more frequent in patients treated with low-dose aspirin. No significant side effects of the treatments could be evidenced in patients or newborns. As there is no argument to prove that low-dose aspirin may have been deleterious, these results support enoxaparin use during such at-risk pregnancies.

French multicentric survey of outcome of pregnancy in women with pregestational diabetes.

OBJECTIVE: To evaluate perinatal outcome in pregnancies in women with type 1 and type 2 diabetes and the influence of preconception care 10 years after the St. Vincent's declaration. RESEARCH DESIGN AND METHODS: A cross-sectional study was conducted in 12 perinatal centers in France in 2000-2001. The main investigated outcomes were perinatal mortality, major congenital malformations, and preterm delivery. RESULTS: Among 435 single pregnancies, 289 (66.4%) were from women with type 1 and 146 (33.6%) from women with type 2 diabetes. Perinatal mortality rate was 4.4% (0.7% national rate), severe congenital malformations rate was 4.1% (2.2% national rate), and preterm delivery rate was 38.2% (4.7% national rate). Preconception care was provided in 48.5% women with type 1 diabetes and in 24.0% women with type 2 diabetes. Women whose first trimester HbA(1c) was >8% had higher rates of perinatal mortality (9.2 vs. 2.5%; odds ratio 3.9; 95% CI 1.5-9.7; P < 0.005), major congenital malformations (8.3 vs. 2.5%; 3.5; 1.3-8.9; P < 0.01), and preterm delivery (57.6 vs. 24.8%; 1.4; 1.1-1.7; P < 0.005) than those with first trimester HbA(1c) <8%. These results are similar to those reported in France in 1986-1988. CONCLUSIONS: Pregnancies in women with diabetes are still poorly planned and complicated by higher rates of perinatal mortality and major congenital malformations. Despite knowledge of the importance of intensified glycemic control before pregnancy, reaching the St. Vincent's target needs further implementation in France.

Antiphospholipid/antiprotein antibodies, hemostasis-related autoantibodies, and plasma homocysteine as risk factors for a first early pregnancy loss: a matched case-control study.

Maternal hypercoagulability is a possible cause of miscarriage during the eighth and ninth weeks of pregnancy, when the placenta replaces the yolk sac. We thus examined associations between putative markers of an acquired hypercoagulable state and the risk of first miscarriage. We conducted a case-control study comparing 743 women who miscarried in weeks 8 and 9 with 743 women who underwent a first provoked abortion, matched for age, number of pregnancies, and time elapsed since abortion. Levels of plasma homocysteine and of various antiphospholipid/antiprotein and hemostasis-related autoantibodies were categorized in 4 strata (percentiles 1-80, 81-95, 96-99, 100 among control patients) and analyzed in conditional logistic regression models. Pregnancy loss was independently associated with positive lupus anticoagulant (matched odds ratio [OR], 2.6; 95% confidence interval [CI], 1.1-6.0), high levels of immunoglobulin M (IgM) antibodies against cardiolipin (OR for percentile 100 versus 0-80, 3.5; CI, 1.2-10.1) and against phosphatidylethanolamine (OR, 4.7; CI, 1.9-12.1), high levels of IgG antibodies against annexin V (OR, 3.2; CI, 1.1-9.1) and against tissue-type plasminogen activator (OR, 19.5; CI, 7.9-48.0), and high homocystinemia (OR, 4.1; CI, 1.3-12.5). A first early pregnancy loss is associated with increased levels of several autoantibodies and of homocysteine.

Anti-protein Z antibodies in women with pathologic pregnancies.

Protein Z deficiencies have recently been described in women with unexplained early fetal loss. Using a new, specifically elaborated, commercially available enzyme-linked immunosorbent assay (ELISA), we performed a case-control study on anti-protein Z immunoglobulin G (IgG) and IgM antibodies in 191 nonthrombotic, nonthrombophilic women with consecutive pathologic pregnancies. Levels of anti-protein Z antibodies were categorized in 3 strata (percentiles 1 through 74, 75 through 97, 98 through 100 among controls). The 2 upper levels of IgG and IgM anti-protein Z antibodies were associated with the risk of unexplained recurrent embryo loss or fetal death independently from habitual antiphospholipid/anticofactor antibodies, and a dose-effect relationship between antibody levels and the clinical risks was evidenced. In women, enhanced immune-complex formation with protein Z may play a role in unexplained embryo losses and, from the 10th week of gestation, may favor hypercoagulability in the maternal placenta side.

High frequency of protein Z deficiency in patients with unexplained early fetal loss.

The protein Z-protein Z-dependent inhibitor complex is a factor Xa inhibitor. Protein Z deficiencies have recently been described in patients with ischemic stroke. As placenta infarction leads to poor pregnancy outcome, we studied protein Z plasma concentrations in nonthrombotic, nonthrombophilic consecutive patients with unexplained pregnancy wastage. A significant amount of protein Z deficiencies was only found in the early fetal loss group (< 1 mg/L; 44 of 200, P < 10(-4)) and mainly in the case of fetal demise between the beginning of the 10th and the end of the 15th week of gestation (odds ratio, 6.7 [3.1-14.8], P < 10(-3)). These deficiencies were not due to partial vitamin K1 deficiency, and at least some of them were constitutional ones. In women, protein Z deficiency may induce an enhanced risk of severe placental insufficiency soon after the connection of maternal and fetal circulations.
