Safety of cotrimoxazole in pregnancy: a systematic review and meta-analysis.

ABSTRACT: INTRODUCTION:Cotrimoxazole is widely prescribed to treat a range of infections, and for HIV-infected individuals it is administered as prophylaxis to protect against opportunistic infections. Some reports suggest that fetuses exposed to cotrimoxazole during early pregnancy may have an increased risk of congenital anomalies. We carried out this systematic review to update the evidence of cotrimoxazole safety in pregnancy. METHODS:Three databases and 1 conference abstract site were searched in duplicate up to October 31, 2013, for studies reporting adverse maternal and infant outcomes among women receiving cotrimoxazole during pregnancy. This search was updated in MEDLINE via PubMed to April 28, 2014. Studies were included irrespective of HIV infection status or the presence of other coinfections. Our primary outcome was birth defects of any kind. Secondary outcomes included spontaneous abortions, terminations of pregnancy, stillbirths, preterm deliveries, and drug-associated toxicity. RESULTS:Twenty-four studies were included for review. There were 232 infants with congenital anomalies among 4196 women receiving cotrimoxazole during pregnancy, giving an overall pooled prevalence of 3.5% (95% confidence interval: 1.8% to 5.1%; ?² = 0.03). Three studies reported 31 infants with neural tube defects associated with first trimester exposure to cotrimoxazole, giving a crude prevalence of 0.7% (95% confidence interval: 0.5% to 1.0%) with most data (29 neural tube defects) coming from a single study. The majority of adverse drug reactions were mild. The quality of the evidence was very low. CONCLUSIONS:The findings of this review support continued recommendations for cotrimoxazole as a priority intervention for HIV-infected pregnant women. It is critical to improve data collection on maternal and infant outcomes.

Project description:BackgroundAbout 3·7 billion doses of ivermectin have been distributed in mass drug administration (MDA) campaigns globally over the past 30 years. At 10-100 times higher than current human doses, ivermectin is a known teratogen in mammals. During these campaigns with recommended doses, pregnant women might be inadvertently exposed. We therefore aimed to evaluate the existing evidence for serious and non-serious adverse events after ivermectin exposure in pregnant women.MethodsFor this systematic review and meta-analysis, we searched relevant databases and trial registry platforms on July 15, 2018, for randomised controlled trials (RCTs) and observational studies that reported adverse events in pregnant women. We did not use language or date restrictions. Outcomes of interest were spontaneous abortions, stillbirths, congenital anomalies, and neonatal death (serious adverse events), as well as maternal morbidity, preterm births, and low birthweight (adverse events). The risk of bias was assessed using the Newcastle-Ottawa Scale for observational studies and the Cochrane Risk of Bias Tool for RCTs. We did the meta-analysis of observational studies and RCTs separately. The quality of evidence was assessed using the GRADE approach. The study protocol is registered with PROSPERO, protocol CRD42016046914.FindingsWe identified 147 records, of which only five observational studies and one RCT were included for quantitative analysis; these studies were published between 1990 and 2008, and were done in six African countries. 893 women with 899 pregancy outcomes were included, of whom 496 pregnant women (500 pregnancy outcomes) received ivermectin inadvertently during MDA campaigns in the observational studies and 397 pregnant women (399 pregnancy outcomes) purposely received ivermectin as part of the open-label RCT. No study reported neonatal deaths, maternal morbidity, preterm births, or low birthweight. It is unclear whether exposure to ivermectin during pregnancy increases the risk of spontaneous abortions and stillbirths (odds ratio [OR] 1·15 [95% CI 0·75-1·78] with very low certainty of evidence for the four observational studies and 0·62 [0·18-2·14] with very low certainty of evidence for the RCT) or congenital anomalies (OR 1·69 [95% CI 0·83-3·41] with very low certainty of evidence for the five observational studies and 1·10 [0·07-17·65] with very low certainty of evidence for the RCT).InterpretationThere is insufficient evidence to conclude on the safety profile of ivermectin during pregnancy. Treatment campaigns should focus additional efforts on preventing inadvertent treatment of pregnant women.FundingUnitaid.

Project description:INTRODUCTION:International guidelines support the use of low molecular weight heparins for the treatment of thromboembolism and thromboprophylaxis during pregnancy. However, evidence of the benefit and harm associated with specific low molecular weight heparins such as enoxaparin is dated. No current systematic review and meta-analysis describing the safety and efficacy of enoxaparin for thromboembolism and thromboprophylaxis during pregnancy exists. METHODS:PubMed, Embase, and Cochrane databases were searched on August 17, 2018 for clinical trials or observational studies in pregnant women receiving enoxaparin; patients with a prosthetic heart valve were excluded. Risk ratios (RR) with 95% confidence intervals (CI) were calculated using a random effects model, and heterogeneity was measured using the I2 statistic. RESULTS:Of the 485 records identified in the search, 24 studies published clinical trials, and observational studies were found dating back to 2000. Only one observational cohort and one randomized control trial focused on the use of enoxaparin for thromboprophylaxis and therefore efficacy was not assessed; the other studies included women with recurrent pregnancy loss (15 studies), history of placental vascular complications (five studies), and recurrent in vitro fertilization failure (two studies) and were therefore analyzed in terms of safety only. Bleeding events were non-significantly more often reported for enoxaparin compared to untreated controls (RR 1.35 [0.88-2.07]) but less often reported for enoxaparin versus aspirin (RR 0.93 [0.62-1.39]); thromboembolic events, thrombocytopenia, and teratogenicity were rarely reported events; in patients with a history of recurrent pregnancy loss, encouragingly the rates of pregnancy loss were significantly lower for enoxaparin compared to untreated controls (RR 0.58 [0.34-0.96]) and enoxaparin?+?aspirin versus aspirin alone (RR 0.42 [0.32-0.56]) as well as observably lower for enoxaparin versus aspirin alone (RR 0.39 [0.15-1.01]), though significant heterogeneity was observed (I2?>?60). CONCLUSION:Literature on the efficacy and safety of enoxaparin for thromboembolism and thromboprophylaxis remains scanty, and therefore efficacy was not assessed; in terms of safety, when including other indications for enoxaparin in pregnancy, we found that enoxaparin was associated with significantly lower complications than aspirin. Given differences in study design and study heterogeneity, pregnancy loss results should be interpreted with caution. Moreover, reports of thromboembolic events, thrombocytopenia, and congenital malformations were rare. FUNDING:Sanofi.

Project description:ObjectiveWe aimed to review and analyze studies focusing on the efficacy of metronidazole in reducing the risk of preterm birth and the safety of metronidazole taking into account the different doses, duration of treatment and routes of administration.Study designsEmbase, Cochrane Library and PubMed were searched up to 29 July 2019 to identify studies assessing metronidazole exposure during pregnancy. Additional studies were identified from reference lists of retrieved papers. Measured outcomes were preterm births (<37 weeks of gestation) and associated delivery outcomes such as spontaneous abortions (≤ 20 weeks of gestation), stillbirths (≥20 weeks of gestation) and low birth weight (<2500 g) irrespective of the period of exposure and major malformations after first-trimester exposure. Overall effect estimates for RCTs and observational studies were calculated using the random-effects model and pooled using Risk Ratios (RR) and Odds Ratios (OR) respectively. ROB-2 and ROBINS-I tool were used to assess Risk of Bias for RCTs and observational studies, respectively.ResultsTwenty-four studies (17 observational studies and 7 RCTs) were selected. Pooled RR was 1.10 (95 % CI 0.78-1.55; n = 7; I2 = 72 %) for preterm birth. Subgroup analysis found RR 1.67; 95 % CI 1.07-2.62; n = 3; I² = 32 %) for treatment duration of ≤3 days among women with a previous preterm delivery. Pooled OR for spontaneous abortion was 1.72 (95 % CI 1.40-2.12; n = 5; I2 = 72 %) and 1.15 (95 % CI 0.98-1.34; n = 12; I2 = 25 %) for major malformations. After exclusion of studies with critical risk of bias, pooled OR were 1.7 (1.42-2.04; n = 3; I2 = 19 %) and 1.13 (0.93-1.36; n = 9; I2 = 28 %) respectively. Among several specific malformations analyzed, only congenital hydrocephaly was significantly increased at 4.06 (95 % CI 1.75-9.42; n = 2; I² = 0%).ConclusionsData do not confirm the efficacy of metronidazole in reducing the risk of preterm birth and associated delivery outcomes. Further research is required to confirm the effect of high dose and short duration of metronidazole treatment on preterm birth among the high-risk group. Regarding the increased odds of spontaneous abortion, RCTs are required to assess the role of the underlying infection. The need for further studies to confirm the risk of congenital hydrocephaly is paramount.

Project description:IntroductionBased on the available data on ovarian cancer during pregnancy, we performed a review and meta-analysis to evaluate the efficacy and safety of platinum-based chemotherapy against ovarian cancer during pregnancy.MethodsWe systematically searched three databases including the PubMed, Embase, and Cochrane Library databases for articles published from January 1986 to December 2020 using the following terms: "ovarian tumors OR ovarian carcinoma OR adnexal masses OR ovarian cancer" AND "pregnancy" AND "chemotherapy." Two authors (Yaping Pei and Yuanfeng Gou) independently searched the literature and extracted data from each eligible study. The outcome measures were overall survival (OS) and progression-free survival (PFS). The OS and PFS of all patients were estimated by Kaplan-Meier survival curves and log-rank tests.ResultsA total of 43 studies including 55 cases of ovarian cancer during pregnancy were selected. Forty-eight patients were comprehensively staged using the International Federation of Gynecology and Obstetrics (FIGO) staging system. Twenty-six of the 48 patients (54.17%) were diagnosed with early-stage disease, while the remaining had advanced stages (II, III, and IV). The mean age at diagnosis was 29.31 years. The majority of patients in this meta-analysis were diagnosed at a mean gestational age of 16.05 weeks. The mean GA at chemotherapy administration was 17.42 weeks. Overall, 55 women gave birth to 56 newborns, including a pair of twins. At the end of follow-up (median 10 months, range 0-73 months), all the children were healthy, except for one child who died 5 days after delivery due to a congenital abnormality. During 2-204 months of follow-up, there were five cases of recurrence, with no evidence of recurrence in the remaining cases. Unfortunately, one patient died 29 months after diagnosis. Neither median overall survival nor median progression-free survival was obtained.ConclusionPlatinum-based chemotherapy may be a good choice for pregnant women with ovarian cancer who want to continue their pregnancy.

Project description:ObjectivesTo review systematically current literature on kidney function changes during pregnancy, in order to estimate the extent of adaptation over the course of both healthy physiological and complicated singleton pregnancies, and to determine healthy pregnancy reference values.MethodsPubMed (NCBI) and EMBASE (Ovid) electronic databases were searched, from inception to July 2017, for studies on kidney function during uncomplicated and complicated pregnancies. Included studies were required to report a non-pregnant reference value of kidney function (either in a non-pregnant control group or as a prepregnancy or postpartum measurement) and a pregnancy measurement at a predetermined and reported gestational age. Kidney function measures assessed were glomerular filtration rate (GFR) measured by inulin clearance, GFR measured by creatinine clearance and serum creatinine level. Pooled mean differences between pregnancy measurements and reference values were calculated for predefined intervals of gestational age in uncomplicated and complicated pregnancies using a random-effects model described by DerSimonian?and?Laird.ResultsTwenty-nine studies met the inclusion criteria and were included in the analysis. As early as the first trimester, GFR was increased by up to 40-50% in physiological pregnancy when compared with non-pregnant values. Inulin clearance in uncomplicated pregnancy was highest at 36-41?weeks, with a 55.6% (53.7; 95% CI, 44.7-62.6?mL/min) increase when compared with non-pregnant values, and creatinine clearance was highest at 15-21?weeks' gestation, with a 37.6% (36.6; 95% CI, 26.2-46.9?mL/min) increase. Decrease in serum creatinine level in uncomplicated pregnancy was most prominent at 15-21?weeks, with a 23.2% (-0.19; 95% CI, -0.23 to -0.15?mg/dL) decrease when compared with non-pregnant values. Eight studies reported on pregnancies complicated by a hypertensive disorder. Meta-regression analysis showed a significant difference in all kidney function parameters when comparing uncomplicated and hypertensive complicated pregnancies.ConclusionsIn healthy pregnancy, GFR is increased as early as the first trimester, as compared with non-pregnant values, and?the kidneys continue to function at a higher rate throughout gestation. In contrast, kidney function is decreased in hypertensive pregnancy. © 2018 The Authors.
