Filter by:The purpose of this study is to determine the predictive value of a single serum determination of activin A and inhibin A for the prognosis of ectopic pregnancy after in Vitro Fertilization (IVF) cycles, in both native and donated oocytes.
Observational study of the use of ultrasound by emergency physicians in the evaluation of patients at risk of ectopic pregnancy.
OBJECTIVE: This study evaluated serum vascular endothelial growth factor (VEGF) concentrations in women with ectopic pregnancy (EP), abnormal intrauterine pregnancy (aIUP) and normal intrauterine pregnancy (nIUP). METHODS: This was a prospective, case-control study comparing serum VEGF concentrations among 72 women with ectopic pregnancy (n=35), abnormal IUP (n=15) and normal IUP (n=22) matched for gestational age. For the determination of serum VEGF concentration a solid phase sandwich ELISA was used. Patients were stratified according to serum VEGF above or below 200pg/mL. RESULTS: The serum level of VEGF was significantly higher in women with ectopic pregnancy (median 211.1 pg/mL; range 5 - 1017.0 pg/mL) than in women with normal IUP (median 5 pg/mL; range 5- 310.6 pg/mL) P < 0.0001. Serum VEGF concentrations did not show any statistically significant difference between women with aIUP (median 231.9 pg/mL range 5 - 813.7 pg /mL ) and EP (median 211.1 pg/mL range 5 - 1017.0 pg/mL). When cut-off concentrations of 200 pg/mL for VEGF were used, a nIUP could be distinguished from an unviable (EP and aIUP) with a sensitive of 53%, specificity of 90.9%, a positive predictive value of 92.9% and a negative predictive value of 46.5%.. CONCLUSIONS: Serum VEGF could not distinguish between an EP and an aIUP. However, serum VEGF concentrations above 200 pg/mL could discriminate a nIUP from an unviable pregnancy (EP or aIUP) with a PPV of 92.9%.
30,000 individuals living in Aarhus County, Denmark by Oct 1997 were randomized into two groups. The intervention group received an invitation to be tested for urogenital Chlamydia trachomatis by use of home-obtained and mailed sample (9,000 individuals). The control group received no intervention (21,000 individuals). Outcome measures: Number of tested individuals, number of detected infections, number of women developing PID, ectopic pregnancy or infertility, number of women giving birth to a child, number of women receiving IVF treatment and number of men developing epididymitis. The hypothesis was that more individuals would be tested and treated for infections and that number of long term fertility complications would decline in the intervention group compared to control group.
In this study we hypothesized that low-dose aspirin therapy (100 mg daily) improves ovarian responsiveness, uterine haemodynamics and clinical pregnancy rates in unselected subjects undergoing IVF/ICSI when the treatment is started concomitantly with controlled ovarian hyperstimulation.
This study examines the safety and acceptability of a novel "two dose" regimen of methotrexate to treat ectopic pregnancy.
The purpose of this study is to identify elements of a patient's demographics, history, and clinical presentation that may aid in differentiating between patients with an ectopic pregnancy, miscarriage, or normal intrauterine pregnancy. This study will also evaluate serial levels of human chorionic gonadotropin in the serum of these patients, as another way to make the diagnosis.
In an attempt to simplify the diagnosis of ectopic pregnancy, the researchers will investigate the presence of specific molecular markers of ectopic pregnancy. The quantification of these (and other proteins) will be performed using the Ciphergen Protein Chip system where serum is sampled with a high-throughput system. The patterns of these peaks will be compared for those with a diagnosis of ectopic pregnancy and normal pregnancy. Later goals of the research will be to identify the actual proteins that correspond to the peaks which discriminate between the two clinical entitles. The goal is to identify a unique protein pattern or protein peak to distinguish a normal intrauterine pregnancy from that of an ectopic implanted gestation.
Three protocols are used to treat ectopic pregnancies: medical treatment by methotrexate, conservative surgery or radical surgery. There are no data about subsequent fertility except in a cohort study. The investigators propose to evaluate the true subsequent fertility with a follow-up of 2 years, in a randomized controlled trial.
