NCT ID: NCT00757718 Completed - Clinical trials for Obstructive Sleep Apnea

Sleep Disordered Breathing and Gestational Hypertension

Start date: December 2008
Phase: N/A
Study type: Interventional

Sleep disordered breathing (SDB) is a common problem in the adult population. By conservative estimates, 4% of the adult female population has SDB. SDB is a recognized cause of hypertension and treating SDB can improve blood pressure control in people with hypertension. More recently, research efforts have looked at SDB as a possible cause of pregnancy induced hypertension (PIH), a condition which complicates 10% of pregnancies. Traditionally, the best way to assess SDB required patients to spend a night sleeping in the Sleep Laboratory. This is inconvenient and for pregnant women often impossible to arrange, considering the short time frame that exists between time of PIH diagnosis and eventual delivery. Researchers at the University of Saskatchewan are now looking at whether an adequate sleep assessment can be performed at the bedside - either in a patient's home or on the hospital ward. The researchers will also look at different treatment options for sleep apnea, to see if these can improve blood pressure control in this patient population, and delay the need for early delivery. The information from this study may result in a detailed sleep assessment becoming part of the complete assessment of women with PIH. There is an association between sleep disordered breathing (SDB) and gestational hypertension (GHTN). Treatment for the SDB may represent an effective addition to the management of the cardiovascular and metabolic perturbations of GHTN We plan to assess women whether treating SDB with one of two methods will improve the management of GHTN. We will also assess if one method is more effective than the other.

NCT ID: NCT00741312 Completed - Pregnancy Clinical Trials

Influence of Physical Exercise on Endothelial Function in Pregnant Women

Start date: October 2008
Phase: Phase 1/Phase 2
Study type: Interventional

The purpose of this study is to determine the effect of regular aerobic exercise on endothelial function in pregnancy.

NCT ID: NCT00719654 Completed - Preeclampsia Clinical Trials

Alterations in the Plasma Proteome of Early-Onset Severe Preeclampsia

Start date: August 2007
Phase:
Study type: Observational

The hypothesis of this study is that many plasma proteins are altered in concentration and structure in preeclampsia and the elucidation of these alterations will add to the poorly understood pathophysiology of preeclampsia. In this study we will compare the maternal plasma proteomes of early-onset severe preeclampsia versus healthy controls, compare protein expression and quantification of the maternal plasma proteome at the time of diagnosis of EOS-preeclampsia to the plasma proteome of the same affected subject at 48 hours post delivery and we will verify the placental expression of differentially expressed or post-translationally modified proteins found in the plasma of women with EOS-preeclampsia.

NCT ID: NCT00683202 Completed - Pregnancy Clinical Trials

Low-Dose Aspirin in in Vitro Fertilization (IVF) and Intracytoplasmic Sperm Injection (ICSI) Treatments

Start date: March 2001
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT00666133 Completed - Preeclampsia Clinical Trials

Treatment Approaches for Preeclampsia in Low-Resource Settings

Start date: April 2008
Phase: N/A
Study type: Interventional

Preeclampsia is a condition unique to pregnancy characterized by the new onset of hypertension and proteinuria. Eclampsia, characterized by maternal seizures, is a serious complication increasing the risk of maternal and infant mortality and morbidity. Magnesium sulfate is the drug of choice for prevention and treating convulsions in severe preeclampsia and eclampsia. Magnesium sulfate is administered parenterally by intramuscular (IM) or intravenous routes (IV). In general a loading dose of 4 to 5 grams of magnesium sulfate is administered intravenously followed by an IM injection every 4 hours or by a continuous IV infusion. The IV regimen achieves more stable serum levels of magnesium but requires the use of an infusion pump for safe delivery and has a greater potential for inadvertent overdose. Although magnesium sulfate has been demonstrated as a safe and effective drug for the treatment and prevention of severe preeclampsia and eclampsia, concerns about the safety of the drug remain. The IM dosing regimen, while potentially safer, requires repeated painful IM injections. These limitations in administration hinder the widespread use of magnesium sulfate despite its demonstrated benefits. The goal of this research is to develop a system of care that avoids overdose and facilitates the use of magnesium sulfate for the treatment of preeclampsia. To this end, a primary objective of this research is to demonstrate the safety of a simple, inexpensive flow controlled pump system (Springfusor®). This randomized study will compare the administration of magnesium sulfate by the Springfusor® controlled pump with an IM regimen, the standard of care in most hospitals in India. The study will document the efficacy and acceptability of each treatment for patients and staff and compare the cost and time elements involved in providing each method.

NCT ID: NCT00654771 Completed - Hypertension Clinical Trials

Comparison of Catheterized and Clean Catch Urine Specimens for Protein/Creatinine Ratio in Preeclampsia Evaluation

UPREE
Start date: July 2005
Phase: N/A
Study type: Observational

The purpose of this prospective study was to examine whether protein/creatinine ratios in catheterized urine specimens correlate to clean catch specimens in pregnant patients being evaluated for preeclampsia.

NCT ID: NCT00653809 Completed - Preeclampsia Clinical Trials

Racial Differences: Nitric Oxide(NO) and Endothelin-1(ET-1) in Preeclampsia (PreE)

Start date: June 2007
Phase: N/A
Study type: Observational

The goal of this study is to examine the activation of markers of endothelial and cardiovascular dysfunctions, from women with high-risk pregnancies. Information from this study will hopefully provide enough information to determine a link between race, the advent of high risk pregnancies and cardiovascular markers. With this information it might be possible to intervene with approved pharmacological treatments.

NCT ID: NCT00583635 Completed - Preeclampsia Clinical Trials

Early Pregnancy Antioxidant Supplementation in the Prevention of Preeclampsia

Start date: May 2004
Phase: N/A
Study type: Observational

Use of Juice Plus+ food supplements, when initiated in the first trimester and used continuously thereafter, will result in a lower incidence of preeclampsia and pregnancy complications. This is a prospective randomized and blinded placebo controlled study sponsored by NSA, LLC of Memphis, TN.

NCT ID: NCT00572793 Completed - Preeclampsia Clinical Trials

A Study to Evaluate the Use of Placenta Protein 13 (PP13) in the First Trimester of Pregnancy as a Diagnostic Aiding Tool in the Assessment of the Risk for Developing Preeclampsia in Women With Low and Unknown Risk

Start date: November 2007
Phase: N/A
Study type: Observational

The purpose of this study is to evaluate whether it is possible to detect changes in the concentration of PP13 in the blood of pregnant women who may go on to develop the complication of preeclampsia later on in the pregnancy, and if these changes can be detected early enough to allow early diagnosis and treatment for prevention of these complications and reduce their damage. This study will test if the PP13 biomarker during the first trimester of pregnancy has the ability to provide assessment of risk for the development of preeclampsia that necessitates delivery before 37 weeks gestation or can predict preeclampsia before 34 weeks gestation.

NCT ID: NCT00533871 Completed - Preeclampsia Clinical Trials

Study to Determine if Serum BNP Levels Are Elevated in Pregnant Women With Pre-Eclampsia

Start date: February 2003
Phase: N/A
Study type: Observational

Preeclampsia is a common disease state occurring in the third trimester of pregnancy, with an incidence of approximately 5-10% in the US. Hypertension (high blood pressure), a primary symptom of pre-eclampsia, may be present in women who were hypertensive prior to becoming pregnant.B-type (also known as brain) natriuretic peptide (BNP) is known to be made and released from the heart ventricles when the heart is strained. There is also evidence that BNP is secreted in the placenta, and may increase in preeclampsia and chronic hypertension in pregnancy.The purpose of the study is to determine if a maternal blood sample analyzed for the quantity of BNP is helpful in differentiating between pre-eclampsia and chronic high blood pressure.
