Maternal inherited thrombophilia and pregnancy outcomes.

ABSTRACT: Thrombophilia is a group of genetical disorders that cause blood to clot abnormally. Thrombophilia is linked to recurrent pregnancy loss, foetal growth restriction, late miscarriages, stillbirth and preeclampsia. Clinicians usually apply the term thrombophilia only to patients with atypical thrombosis. A successful outcome of pregnancy requires an efficient uteroplacental circulation. Since this system may be compromised by disorders associated with a prothrombotic state, it was postulated that maternal thrombophilia might be a risk factor for preeclampsia and intrauterine growth retardation. The study included 459 pregnant women with gestational ages ranging from 14 weeks to 28 weeks and the patients in the study were tested for hereditary thrombophilia. The type of thrombophilic mutation most common found was the MTHFR mutation (25.7%), followed by the prothrombin gene mutation (20.9%) and the Leiden factor V mutation (15.7%). Also 15.03% patients had been diagnosed with preeclampsia and 6.75% of the pregnant women had IUGR fetuses.

Project description:BACKGROUND:Hypothyroidism in pregnancy is an arena of ongoing research, with international conflicts regarding screening, management, and outcomes. Various studies have described the outcomes depending on geographical and international diagnostic criteria. No study has been conducted in this regard from the region of Pakistan. Therefore, we aim to report the clinical features and maternal outcomes of hypothyroid pregnancies and compare the maternal outcomes between uncontrolled and controlled TSH levels in the preconception as well as the gestational period. METHODS:We conducted a cross-sectional retrospective study on 718 cases in the Aga Khan University Hospital after ethical approval. We collected information on pregnant females who have diagnosed hypothyroidism before conception or during their antenatal period. We noted the maternal characteristics and maternal comorbidities. Laboratory data were recorded for thyroid stimulating hormone levels before conception and during gestation. We recorded maternal outcomes as pregnancy loss (including miscarriage, stillbirth/intrauterine death, medical termination of pregnancy and ectopic pregnancy), gestational hypertension, pre-eclampsia, postpartum hemorrhage, placental abruption, and modalities of delivery. Data analysis was performed on Statistical Package for the Social Sciences version 20.0. RESULTS:Among 708 hypothyroid women 638 had live births. Postpartum hemorrhage was the most frequent maternal outcome (38.8%). The emergency cesarean section occurred in 23.4% of cases. We determined TSH levels in 53.2, 56.7, 61.7 and 66.6% of cases in preconception, 1st, 2nd, and 3rd trimester periods. A significant association existed between cesarean section and preconception thyrotropin levels >?2.5 mIU/L, whereas postpartum hemorrhage was significantly associated with thyrotropin levels >?2.5 mIU/L in the preconception and third trimester. CONCLUSION:Successful live births in our patients were complicated by maternal postpartum hemorrhage and a frequent number of emergency cesarean section.

Project description:Pregnancy in kidney disease is considered high risk, but the degree of this risk is unclear. We tested the hypothesis that kidney disease in pregnancy is associated with adverse maternal and fetal outcomes.Retrospective study comparing pregnant women with and without kidney disease.Using data from an integrated health care delivery system from 2000 through 2013, a total of 778 women met the criteria for kidney disease. Using a pool of 74,105 women without kidney disease, we selected 778 women to use for matches for the women with kidney disease. These women were matched 1:1 by age, race, and history of diabetes, chronic hypertension, liver disease, and connective tissue disease.Kidney disease was defined using the NKF-KDOQI definition for chronic kidney disease or International Classification of Diseases, Ninth Revision codes prior to pregnancy or serum creatinine level > 1.2mg/dL and/or proteinuria in the first trimester.Maternal outcomes included preterm delivery, delivery by cesarean section, preeclampsia/eclampsia, length of stay at hospital (>3 days), and maternal death. Fetal outcomes included low birth weight (weight < 2,500g), small for gestational age, number of admissions to neonatal intensive care unit, and infant death.Compared with women without kidney disease, those with kidney disease had 52% increased odds of preterm delivery (OR, 1.52; 95% CI, 1.16-1.99) and 33% increased odds of delivery by cesarean section (OR, 1.33; 95% CI, 1.06-1.66). Infants born to women with kidney disease had 71% increased odds of admission to the neonatal intensive care unit or infant death compared with infants born to women without kidney disease (OR, 1.71; 95% CI, 1.17-2.51). Kidney disease also was associated with 2-fold increased odds of low birth weight (OR, 2.38; 95% CI, 1.64-3.44). Kidney disease was not associated with increased risk of maternal death.Data for level of kidney function and cause of death not available.Kidney disease in pregnancy is associated independently with adverse maternal and fetal outcomes when other comorbid conditions are controlled by matching.
