Prevention of mother-to-child transmission of HIV in Thailand: physicians' attitudes on zidovudine use, pregnancy termination, and willingness to provide care.

We administered a survey to Thai physicians, using regular mail, on their attitudes and practices regarding zidovudine (ZDV) use and pregnancy termination in HIV-infected pregnant women. We surveyed their willingness to care for these patients as well. In 1997, 79.5% of 480 respondents reported that they did not routinely use perinatal ZDV prophylaxis. Predictors of failure to use ZDV found to be significant in our logistic regression model included practice outside of Bangkok (odds ratio [OR] = 2.0), belief that ZDV is not cost effective (OR = 2.5), unfamiliarity with AIDS Clinical Trials Group (ACTG) 076 results (OR = 2.5), and failure to screen for HIV routinely (OR = 4.9). Elective abortion for HIV-infected women was advocated by 45.3% of respondents. Factors associated in multivariable analysis with this preference included specialty training in obstetrics/gynecology (OR = 1.8), practice inside Bangkok (OR = 2.0), male gender (OR = 1.9), and treatment of < or =2 HIV-infected patients yearly (OR = 1.8). A significant proportion of respondents described themselves as unwilling to perform pelvic examinations (19.2%), vaginal deliveries (30.7%), or cesarean deliveries (39.5%) on women who were known to be infected with HIV. We conclude that many Thai obstetric providers are reluctant to care for HIV-infected women, do not routinely use perinatal ZDV prophylaxis, and prefer to terminate pregnancies among HIV-infected patients. Physician education concerning the value of HIV screening and antiretroviral therapy in HIV-infected pregnant women is needed urgently in Thailand.     

A meta-analysis of pregnancy outcomes in women with polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a common reproductive disorder associated with many characteristic features, including hyperandrogenaemia, insulin resistance and obesity which may have significant implications for pregnancy outcomes and long-term health of the woman. This meta-analysis was conducted to evaluate the risk of pregnancy and neonatal complications in women with PCOS. Electronic databases were searched for the following MeSH headings: PCOS, hyperandrogenism, pregnancy outcome, pregnancy complications, diabetes mellitus, type II. A handsearch of human reproduction and fertility and sterility was also conducted. Studies in which pregnancy outcomes in women with PCOS were compared with controls were considered for inclusion in this meta-analysis. Fifteen of 525 identified studies were included, involving 720 women presenting with PCOS and 4505 controls. Women with PCOS demonstrated a significantly higher risk of developing gestational diabetes [odds ratio (OR) 2.94; 95% confidence interval (CI): 1.70-5.08], pregnancy-induced hypertension (OR 3.67; 95% CI: 1.98-6.81), pre-eclampsia (OR 3.47; 95% CI: 1.95-6.17) and preterm birth (OR 1.75; 95% CI: 1.16-2.62). Their babies had a significantly higher risk of admission to a neonatal intensive care unit (OR 2.31; 95% CI: 1.25-4.26) and a higher perinatal mortality (OR 3.07; 95% CI: 1.03-9.21), unrelated to multiple births. In conclusion, women with PCOS are at increased risk of pregnancy and neonatal complications. Pre-pregnancy, antenatal and intrapartum care should be aimed at reducing these risks.     

Cumulative psychosocial stress,coping resources,and preterm birth

Preterm birth constitutes a significant international public health issue, with implications for child and family well-being. High levels of psychosocial stress and negative affect before and during pregnancy are contributing factors to shortened gestation and preterm birth. We developed a cumulative psychosocial stress variable and examined its association with early delivery controlling for known preterm birth risk factors and confounding environmental variables. We further examined this association among subgroups of women with different levels of coping resources. Utilizing the All Our Babies (AOB) study, an ongoing prospective pregnancy cohort study in Alberta, Canada (n?=?3,021), multinomial logistic regression was adopted to examine the independent effect of cumulative psychosocial stress and preterm birth subgroups compared to term births. Stratified analyses according to categories of perceived social support and optimism were undertaken to examine differential effects among subgroups of women. Cumulative psychosocial stress was a statistically significant risk factor for late preterm birth (OR?=?1.73; 95 % CI?=?1.07, 2.81), but not for early preterm birth (OR?=?2.44; 95 % CI?=?0.95, 6.32), controlling for income, history of preterm birth, pregnancy complications, reproductive history, and smoking in pregnancy. Stratified analyses showed that cumulative psychosocial stress was a significant risk factor for preterm birth at <37 weeks gestation for women with low levels of social support (OR?=?2.09; 95 % CI?=?1.07, 4.07) or optimism (OR?=?1.87; 95 % CI?=?1.04, 3.37). Our analyses suggest that early vulnerability combined with current anxiety symptoms in pregnancy confers risk for preterm birth. Coping resources may mitigate the effect of cumulative psychosocial stress on the risk for early delivery.     

Effect of maternal HIV and malaria infection on pregnancy and perinatal outcome in Zimbabwe

OBJECTIVE: To investigate the effect of isolated or concomitant infection with malaria and HIV on pregnancy and neonatal outcome. METHODS: Data were collected on pregnant women admitted during the rainy seasons in the obstetric division of a district referral hospital in northern Zimbabwe in 2000 and 2001. The effects of malaria and HIV infection were determined by multivariate analysis. RESULTS: The prevalence of HIV seropositivity and symptomatic malaria in 986 pregnant women was 8.3% and 14.7%, respectively. HIV-infected women were more likely to develop malaria attacks during pregnancy than seronegative women (odds ratio [OR] = 3.96, 95% confidence interval (CI): 2.42-6.46). Malaria and HIV infections were associated with increased risk of stillbirth (OR = 4.74, 95% CI: 1.34-16.78) and preterm delivery (OR = 4.10, 95% CI: 2.17-7.75), respectively. They were independently associated with increased risk of low birth weight (malaria: OR = 10.09, 95% CI: 6.50-15.65; HIV: OR = 3.16, 95% CI: 1.80-5.54) and very low birth weight (malaria: OR = 5.04, 95% CI: 1.00-25.43; HIV: OR = 10.74, 95% CI: 2.12-54.41), low Apgar score (malaria: OR = 4.45, 95% CI: 1.42-13.94; HIV: OR = 5.94, 95% CI: 1.66-21.30), and fetal growth restriction (malaria: OR = 3.98, 95% CI: 2.51-6.30; HIV: OR = 4.07, 95% CI: 2.40-6.92). Dual infection with malaria and HIV was associated with increased risk of maternal, perinatal, and early infant death. CONCLUSIONS: Women with single HIV or malaria infection have a significantly increased risk of adverse outcomes of pregnancy and childbirth. Dual infection has additional detrimental effects on maternal and infant survival in an area where HIV and malaria coexist.     

Zidovudine use during pregnancy among HIV-infected women on Medicaid

OBJECTIVES: This study estimates the rate of zidovudine (ZDV) use during pregnancy among HIV-infected women receiving Medicaid. The rates of ZDV use during pregnancy are compared before (preperiod) and after (postperiod) the 1994 publication of US Public Service Task Force guidelines, recommending use of ZDV during pregnancy. The authors also compare and contrast the correlates of ZDV use during pregnancy in each of the preguideline and postguideline periods. METHODS: New Jersey AIDS/HIV surveillance data and paid Medicaid claims data between 1992 and 1996 were merged to examine ZDV use during pregnancy. Among ZDV users, the authors also examined persistence of ZDV use during the 3 months preceding delivery. In these analyses, the authors examined care received during pregnancy and differentiated routine medical care from pregnancy-specific care. Correlates of intrapregnancy ZDV use were examined using chi2 analysis and robust regression techniques that correct for correlation among repeated observations. RESULTS: Use of ZDV during pregnancy steadily increased from 13% in 1992 to 70% in 1996, with the upward trend beginning before the release of the guidelines. Averaged over the full preperiod (1992-1994), the rate was 29%, increasing to 57% during the full postperiod (1995-1996). Women with no health care during pregnancy did not receive any ZDV prophylaxis. Women who had some health care contacts, but did not receive pregnancy-specific care, had low rates of ZDV use that did not increase after the promulgation of the guidelines (21% in preperiod and 27% in postperiod). Women who received pregnancy-specific care, whether from obstetrician-gynecologists (OB-GYNs) or other providers, substantially increased their use of ZDV in the postguideline period (from 37% to 63% for those who saw OB-GYNS, and from 20% to 59% for those who received pregnancy-specific care from other providers). However, among users of ZDV, only a minority (24%) used ZDV persistently during the 3 months preceding delivery. African American women were less likely to be persistent ZDV users, even after controlling for other factors. CONCLUSIONS: The study highlights the underutilization of ZDV by women who did not receive pregnancy-related care, even after the publication of guidelines. Lack of pregnancy-specific medical care during pregnancy is an important barrier to ZDV prophylaxis. This study confirms that the receipt of prenatal care during pregnancy is a key intervening variable in the real world application of the PHS guidelines and underscores the importance of proactive efforts to provide prenatal care to pregnant women with HIV.     

Paternal support and preterm birth, and the moderation of effects of chronic stress: a study in Los Angeles County mothers

Maternal psychosocial stress is an important risk factor for preterm birth, but support interventions have largely been unsuccessful. The objective of this study is to assess how support during pregnancy influences preterm birth risk and possibly ameliorates the effects of chronic stress, life event stress, or pregnancy anxiety in pregnant women. We examined 1,027 singleton preterm births and 1,282 full-term normal weight controls from a population-based retrospective case–control study of Los Angeles County, California women giving birth in 2003, a mostly Latina population (both US-born and immigrant). We used logistic regression to assess whether support from the baby’s father during pregnancy influences birth outcomes and effects of chronic stress, pregnancy anxiety, and life event stress. Adjusted odds of preterm birth decreased with better support (OR 0.73 [95%CI 0.52, 1.01]). Chronic stress (OR 1.46 [95%CI 1.11, 1.92]), low confidence of a normal birth (OR 1.57 [95% CI 1.17, 2.12]), and fearing for the baby’s health (OR 1.67 [95%CI 1.30, 2.14]) increased preterm birth risk, but life events showed no association. Our data also suggested that paternal support may modify the effect of chronic stress on the risk of preterm birth, such that among mothers lacking support, those with moderate-to-high stress were at increased odds of delivering preterm (OR 2.15 [95%CI 0.92, 5.03]), but women with greater support had no increased risk with moderate-to-high chronic stress (OR 1.13 [95%CI 0.94, 1.35]). Paternal support may moderate the effects of chronic stress on the risk of preterm delivery.     

Effect of prenatal zidovudine on disease progression in perinatally HIV-1-infected infants

OBJECTIVE: To determine the influence of prenatal zidovudine (ZDV) prophylaxis on the course of HIV- 1 infection in children by comparing the clinical outcome of infants born to HIV- 1-seropositive mothers who did versus those who did not receive ZDV during pregnancy. METHODS: Medical records of HIV-1-seropositive mothers and their infants were reviewed retrospectively. Participants were divided according to maternal ZDV use: no ZDV (n = 152); ZDV (n = 139). The main outcome measure was rapid disease progression (RPD) in the infant, defined as occurrence of a category C disease or AIDS-related death before 18 months of age. RESULTS: HIV vertical transmission rates were significantly different (no ZDV versus ZDV: 22.3% versus 12.2%; p = .034). Among infected infants, the RPD rate was 29.4% in the no ZDV group compared with 70.6% in the ZDV group (p = .012), and prematurity was significantly associated with a higher risk of RPD (p = .027). CONCLUSIONS: The rate of RPD was significantly higher among perinatally infected infants born to HIV-infected mothers treated with ZDV than among infected infants born to untreated mothers. The decreased proportion of infected infants with nonrapid disease progression in the former group might be related to the ability of ZDV to block intrapartum transmission preferentially and also to nonrapid disease progression resulting from intrapartum transmission.     

Rethinking approaches to risk reduction for injection drug users: differences in drug type affect risk for HIV and hepatitis C virus infection through drug-injecting networks

OBJECTIVE: To identify and compare the drug-injecting network characteristics of cocaine and heroin injectors associated with a risk of HIV and hepatitis C virus (HCV). METHODS: Active injectors were recruited from syringe exchange and methadone programs. Characteristics of all participants and their social networks were elicited. Regression analysis using generalized estimating equations examined the network characteristics of injection drug users (IDUs) relative to cocaine or heroin use in the past 6 months. RESULTS: Of 282 IDUs, 228 (81%) used cocaine and 54 (19%) used heroin as their primary injected drug. In analyses adjusted for age and gender, cocaine injectors compared with heroin injectors were more likely to live in unstable housing (odds ratio [OR] = 3.55, 95% confidence interval [CI]: 1.49 to 8.40), self-report HCV infection (OR = 4.69, 95% CI: 2.14 to 10.31), and have a greater number of IDUs in their social network (OR = 1.61, 95% CI: 1.14 to 2.28) and were less likely to be polydrug users (OR = 0.06, 95% CI: 0.02 to 0.16) and to have social support (OR = 0.97, 95% CI: 0.95 to 0.99). The injecting networks of cocaine users were more likely to have members who were older (OR = 1.08, 95% CI: 1.04 to 1.12), had a history of shooting gallery use (OR = 2.27, 95% CI: 1.08 to 4.76), and had shorter relationships with the subject (OR = 0.91, 95% CI: 0.85 to 0.97). CONCLUSIONS: Beyond personal behaviors, HIV and HCV infection risk seems to be linked to social network traits that are determined by drug type. Prevention efforts to control the spread of bloodborne viruses among IDUs could benefit from tailoring interventions according to the type of drug used.     

HIV-1 viral load and other risk factors for mother-to-child transmission of HIV-1 in a breast-feeding population in Cote d'Ivoire

Short-course antiretroviral regimens have been evaluated to reduce mother-to-child transmission of HIV in resource-limited settings. This report from Abidjan, Cote d'Ivoire, examines the risk factors for HIV transmission by 1 and 24 months among breast-feeding women. Eligible HIV-1-seropositive pregnant women enrolled in this randomized double-blind clinical trial were randomly assigned to receive either oral zidovudine (ZDV) (n = 126) prophylaxis or placebo (n = 124). Maternal prophylaxis began at 36 weeks of gestation (300 mg ZDV twice daily antepartum and 300 mg every 3 hours intrapartum); there was no neonatal prophylaxis component. The cumulative risk of transmission in the treatment group was 11.9% and 22.1% by 1 and 24 months, respectively. In adjusted analyses, viral load at enrollment was the strongest predictor of transmission (per log increment: odds ratio [OR] = 4.8, 95% confidence interval [CI]: 2.5-9.5 at 1 month; OR = 5.7; 95% CI: 3.1-10.8 at 24 months). Overall, ZDV prophylaxis was not significantly protective for infection at 1 or 24 months. Comparing ZDV with placebo following dichotomization of viral load (<50,000 vs. > or =50,000 copies/mL) at enrollment, however, there was a significant effect of ZDV seen only among those women with a low viral load at enrollment. The substantial risk of transmission despite ZDV prophylaxis, particularly among those with higher viral loads, underscores the need to find more effective regimens appropriate for use in resource-limited settings.     

First-trimester bleeding and pregnancy outcome in singletons after assisted reproduction

BACKGROUND: First-trimester bleeding is frequent in assisted reproductive technique (ART) pregnancies. It is unknown whether first-trimester bleeding, if not ending in a spontaneous abortion, negatively influences further pregnancy outcome in ART in singletons. METHODS: Data were obtained from our ART database (1993-2002), with 1432 singleton ongoing pregnancies being included in this study. The outcome measures-second-trimester and third-trimester bleeding, preterm contraction rates, pregnancy duration, birthweight, Caesarean section rates, intrauterine growth retardation (IUGR), preterm prelabour rupture of membranes (P-PROM), neonatal intensive care unit (NICU) admission and perinatal mortality-were compared in the groups with and without first-trimester bleeding. RESULTS: Significantly more singleton pregnancies resulted from a vanishing twin in the group with first-trimester bleeding (8.7%) than in the controls (4.0%). A correlation was found between the incidence of first-trimester bleeding and the number of embryos transferred. First-trimester bleeding led to increased second-trimester [odds ratio (OR)=4.56; confidence interval (CI)=2.76-7.56] and third-trimester bleeding rates (OR=2.85; CI=1.42-5.73), P-PROM (OR=2.44; CI=1.38-4.31), preterm contractions (OR=2.27; CI=1.48-3.47) and NICU admissions (OR=1.75; CI=1.21-2.54). First-trimester bleeding increased the risk for preterm birth (OR=1.64; CI=1.05-2.55) and extreme preterm birth (OR=3.05; CI=1.12-8.31). CONCLUSIONS: First-trimester bleeding in an ongoing singleton pregnancy following ART increases the risk for pregnancy complications. The association between first-trimester bleeding, the number of embryos transferred and adverse pregnancy outcome provides a further argument in favour of single-embryo transfer.     

Addition of single-dose tenofovir and emtricitabine to intrapartum nevirapine to reduce perinatal HIV transmission

OBJECTIVE: To determine the impact of adjuvant single-dose peripartum tenofovir/emtricitabine (TDF/FTC) on intrapartum/early postpartum HIV transmission. METHODS: In the setting of routine short-course zidovudine (ZDV) and peripartum nevirapine (NVP) for perinatal HIV prevention, participants were randomized to single-dose TDF (300 mg)/FTC (200 mg) or to no intervention in labor. Six-week infant HIV infection was compared according to actual-use drug regimens. RESULTS: Of 397 women randomized, 355 (89%) had infants who were alive and active at 6 weeks postpartum. Of these, 18 (5.1%) were infected in utero and 6 (1.8%) were infected intrapartum/early postpartum. Among the 243 who used ZDV and NVP, intrapartum/early postpartum transmission was not reduced among infants whose mothers received TDF/FTC compared with those who did not (2 of 123 [1.6%] vs. 3 of 109 [2.8%]; P = 0.67). Among the 49 infants whose mothers did not receive antenatal ZDV but who had confirmed NVP ingestion, transmission similarly did not differ (0 of 19 [0%] vs. 1 of 26 [3.4%]). TDF/FTC was not significantly associated with reduced overall transmission (odds ratio [OR] = 0.7, 95% confidence interval [CI]: 0.3 to 1.6), even when other antiretroviral drugs were considered (adjusted OR = 0.8, 95% CI: 0.3 to 1.8). CONCLUSIONS: Adjuvant peripartum single-dose TDF/FTC did not reduce perinatal transmission. Whether a higher dose might be effective remains unknown but should be studied in settings in which NVP is used without antenatal ZDV.     

低出生体重儿的发生与母亲既往生育史的相关性分析

目的探讨母亲既往生育史对单胎活产低出生体重儿发生的影响因素。方法选取375名住院产妇所生的单胎活产低出生体重儿（LBW）,与同期分娩的单胎活产正常体重儿5157例进行病例对照分析,比较母亲既往生育史对低出生体重儿发生的影响。结果既往自然流产史、早产史和不良孕产史是LBW发生的危险因素（OR=1.57 95%CI1.110-2.25）、（OR=4.84 95%CI 2.01-11.66）、（OR=2.09 95%CI 1.22-3.57）,并且主要针对于早产LBW（OR=1.6595%CI 1.11-2.44）、（OR=6.55 95%CI 2.70-15.91）、（OR=2.18 95%CI 1.21-3.91）,既往低出生体重史是足月LBW发生的危险因素（OR=7.93 95%CI 1.72-36.46）结论 LBW的发生与既往自然流产史、早产史、不良孕产史、低出生体重史密切相关。对以上这些妇女再次怀孕的孕前、孕期均应做好保健服务,以有效减少LBW的发生。     

Association between preterm birth and vaginal colonization by mycoplasmas in early pregnancy

To examine the association between colonization by two newly classified species of genital ureaplasmas (Ureaplasma parvum and U. urealyticum) in early pregnancy and subsequent late abortion or preterm birth at <34 weeks of gestation, four species of genital mycoplasmas--Mycoplasma genitalium, M. hominis, U. parvum, and U. urealyticum--as well as Chlamydia trachomatis and Neisseria gonorrhoeae were examined by PCR-based methods in a prospective cohort study of 877 women with singleton pregnancies at <11 weeks of gestation. Antibiotics were used only in cases in which C. trachomatis and/or N. gonorrhoeae was detected. Multivariate logistic-regression analysis was used to assess independent risk factors after taking maternal low body weight and past history of preterm birth into account. M. genitalium, M. hominis, U. parvum, U. urealyticum, C. trachomatis, and N. gonorrhoeae were detected in 0.8%, 11.2%, 52.0%, 8.7%, 3.2%, and 0.1% of these 877 women, respectively. Twenty-one (2.4%) women experienced late abortion or preterm birth at <34 weeks of gestation. Three factors-detection of U. parvum in the vagina (odds ratio [OR], 3.0; 95% confidence interval [CI], 1.1 to 8.5); use of antibiotics, such as penicillin and cefatrizine, for incidental inflammatory complications before 22 weeks of gestation (OR, 4.2; 95% CI, 1.6 to 10.0); and past history of preterm birth (OR, 10.4; 95% CI, 2.7 to 40.5)-were independently associated with late abortion and preterm birth. In conclusion, vaginal colonization with U. parvum, but not U. urealyticum, is associated with late abortion or early preterm birth.     

The interaction between the maternal BMI and angiogenic gene polymorphisms associates with the risk of spontaneous preterm birth

Obesity is associated with an increased level of inflammation. Interactions between inflammatory and angiogenic pathways are implicated in the major pregnancy disorders. The aim of this study was to investigate whether functional polymorphisms in angiogenesis-regulating genes (VEGFA rs699947, VEGFA rs3025039, KDR rs2071559 and ANGPT1 rs2507800) interact with the maternal BMI to modify the risk of a spontaneous preterm birth (sPTB). We conducted a nested case-control study of 1190 nulliparous Caucasian women (107 sPTBs and 1083 controls). Spontaneous PTB was defined as spontaneous preterm labour or a preterm premature rupture of membranes resulting in a preterm birth at <37 weeks of gestation. DNA was extracted from the peripheral blood and genotyped using the Sequenom MassARRAY system. Among overweight or obese women (BMI ≥25), the VEGFA rs699947 AA genotype was associated with a higher risk of sPTBs [odds ratio (OR) = 2.4, 95% confidence interval (CI): 1.4-4.6, P = 0.001] and a significant interaction between the BMI and the polymorphism was detected (OR = 4.2, 95% CI: 1.7-10.9, P = 0.003). Among women with a BMI <25, ANGPT1 rs2507800 AA genotype was associated with a higher risk of sPTB (OR = 2.3, 95% CI: 1.2-4.4, P= 0.02) and a significant interaction between BMI and the polymorphism was detected (OR = 3.3, 95% CI: 1.1-9.3, P = 0.02). All results remained significant after adjusting for potential confounding factors. The maternal BMI interacts with angiogenesis-regulating gene polymorphisms to modify the risk of sPTBs. Trial Registry Name: Screening nulliparous women to identify the combinations of clinical risk factors and/or biomarkers required to predict pre-eclampsia, small-for-gestational-age babies and spontaneous preterm birth (https://www.anzctr.org.au).

Evaluating programs to prevent mother-to-child HIV transmission in two large Bangkok hospitals, 1999-2001

The 2 largest maternity hospitals in Bangkok implemented comprehensive programs to prevent mother-to-child HIV transmission in 1998. We conducted a cross-sectional survey of post-partum HIV-infected women in 1999 through 2001 to evaluate these programs. Women were given structured interviews at 0 to 3 days, 1 month, and 2 months postpartum. Medical records of women and their newborns were reviewed. Of 488 enrolled women, 443 (91%) had antenatal care: 391 (88%) at study hospitals and 52 (12%) elsewhere. The HIV diagnosis was first known before pregnancy for 61 (13%) women, during pregnancy for 357 (73%) women, during labor for 22 (5%) women, and shortly after delivery for 48 (10%) women. Antenatal zidovudine (ZDV) was used by 347 (71%) women, and intrapartum ZDV was used by 372 (76%) women. Twelve (55%) of the 22 women who first learned of their HIV infection during labor took intrapartum ZDV. All 495 newborn infants started prophylactic ZDV; the first dose was given within 12 hours for 491 (99%) children. Ten (2%) children were breast-fed at least once by their mother, and 10 (2%) were breast-fed at least once by someone else. Although uptake of services was high, inconsistent antenatal care, fear of stigmatization, and difficulty in disclosing HIV status prevented some women from using services.     

Risk of Pregnancy Complications and Low Birth Weight Offsprings in Korean Women With Rheumatic Diseases: A Nationwide Population-Based Study

BackgroundTo determine the risk of pregnancy complications and adverse offspring outcomes in Korean women with rheumatic diseases (RDs).MethodsWomen aged 20–44 years with pregnancies ending in delivery were identified from the National Health Insurance Service-National Health Information Database (2009–2016). Women with RD including systemic lupus erythematosus (SLE), seropositive rheumatoid arthritis (SPRA), and ankylosing spondylitis (AS) (n = 4,284) were age-matched with controls (n = 26,023). Outcome variables included threatened abortion (TA), preterm birth (PB), preeclampsia/eclampsia (PE/E), intrauterine growth retardation (IGR), urinary tract infection, low birth weight (LBW) offsprings, and offspring death within 1 year of birth.ResultsWomen with RDs had increased risks for cesarean section delivery (odds ratio [OR], 1.5; 95% confidence interval [CI], 1.4–1.6), TA (OR, 1.4; 95% CI, 1.2–1.5), PB (OR, 2.4; 95% CI, 1.9–3.2), PE/E (OR, 4.4; 95% CI, 3.3–5.9), and IGR (OR, 2.4; 95% CI, 2.0–3.1) than the controls. The risk of pregnancy complications was increased in SLE and SPRA pregnancies but not in AS pregnancies. Offsprings of women with RDs had an increased risk of LBW (OR, 4.0; 95% CI, 3.2–4.9). The offspring mortality rate within 1 year of birth was higher in women with RDs (6.2/10,000 persons) than in the controls (4.9/10,000 persons).ConclusionWomen with RDs are at a risk of developing pregnancy complications, and the risk of LBW offsprings and offspring death within 1 year of birth is increased in these women. Therefore, this population requires special attention during their childbearing years.
