• Iron deficiency anemia in pregnancy. Current opinion in obstetrics & gynecology Igbinosa, I., Berube, C., Lyell, D. J. 2022; 34 (2): 69-76

  Abstract

  PURPOSE OF REVIEW: Anemia in pregnancy is associated with increased maternal and neonatal morbidity. There is increasing awareness amongst obstetricians about the need to screen for iron deficiency anemia (IDA), as well as growing literature on diagnosis and treatment. This review aims to summarize causes, consequences, treatment, and evaluation of IDA in pregnancy.RECENT FINDINGS: National guidelines provide varying guidance on diagnosis and treatment of IDA in pregnancy. Serum ferritin is a helpful adjunct for the diagnosis of IDA. Oral iron remains an option for treatment; absorption is improved with every other day dosing and is effective for patients able to tolerate. Emerging studies on modern generations of intravenous (IV) iron demonstrate shorter infusion times and improved safety profiles. Notably, recent UK guidelines provide consideration for universal IV iron supplementation for treatment of anemia beyond 34 weeks of pregnancy.SUMMARY: Iron, in dietary, oral, and IV forms, has been found effective in resolving anemia in pregnancy. Pregnant people with IDA in the third trimester are more likely to benefit from IV iron. Future studies designed and powered to assess maternal and perinatal morbidity indicators and blood transfusion rates can strengthen recommendations.

  Abstract

  Obstetric complications impact over a third of women globally, but are underrepresented in clinical research. Little is known about the comprehensive obstetric clinical trial landscape, how it compares to other fields, or factors associated with the successful completion of obstetric trials.To characterize obstetric clinical trials registered on ClinicalTrials.gov with the primary objective of identifying features associated with early discontinuation and results reporting.This is a cross-sectional study with descriptive, logistic regression and cox regression analyses of clinical trials registered on ClinicalTrials.gov. Our primary exposure variables were trial focus (obstetric or non-obstetric) and trial funding (industry, United States government or academic). We conducted additional exploratory analyses of other trial features including design, enrollment, and therapeutic focus. We examined the associations of exposure variables and other trial features with two primary outcomes: early discontinuation and results reporting.We downloaded data for all studies (n=332,417) registered on ClinicalTrials.gov from October 1, 2007 to March 9, 2020 from the Aggregate Analysis of the ClinicalTrials.gov database. We excluded studies with a non-interventional design (n=63,697) and those registered before October 1, 2007 (n=45,209). 4,276 (1.9%) obstetric trials (i.e. interventional studies), and 219,235 (98.1%) non-obstetric trials were compared. Among all trials, 2.8% of academic-funded trials, 1.9% of United States government-funded trials, and 0.4% of industry-funded trials focused on obstetrics. The quantity of obstetric trials increased over time (10.8% annual growth rate). Compared to non-obstetric trials, obstetric trials had a greater risk of early discontinuation (adjusted hazard ratio 1.40, 95% confidence interval: 1.21 to 1.62, p<0.0001) and similar odds of results reporting (adjusted odds ratio 0.89, 95% confidence interval: 0.72 to 1.10, p=0.19). Among obstetric trials funders after controlling for confounding variables, United States government-funded trials were at lowest risk of early discontinuation (US government adjusted hazard ratio 0.23, 95% confidence interval 0.07 to 0.69, p=0.009, industry reference; academic adjusted hazard ratio 1.04, 95% confidence interval 0.62 to 1.74, p=0.88). Academic-funded trials had the lowest odds of results reporting after controlling for confounding variables (academic institutions adjusted odds ratio 0.39, 95% confidence interval 0.22 to 0.68, p=0.0009; industry reference; US government adjusted odds ratio 1.06 95% confidence interval 0.53 to 2.09, p=0.87).Obstetric trials represent only 1.9% of all clinical trials in ClinicalTrials.gov and have comparatively poor completion. All stakeholders should commit to increasing the number of obstetric trials and improving their completion and dissemination to ensure clinical research reflects the obstetric burden of disease and advances maternal health.
