Secondary hyperparathyroidism is associated with postpartum blood pressure in preeclamptic women and normal pregnancies

Systematic Review and Meta-Analysis of 24-Hour Ambulatory Blood Pressure Monitoring in Pregnancy and Postpartum Periods

PURPOSE

Early detection and management of hypertensive disorders during pregnancy and postpartum are essential. This systematic review and meta analysis aimed: (1) to examine the state of 24-hour ambulatory blood pressure (ABP) use, and (2) in a subset of studies, evaluate 24-hour ABP parameters in the prediction and identification of Hypertensive Disorders of Pregnancy (HDP).

METHODS

A comprehensive literature search was conducted in March of 2022 for English language studies published after 2000. In a subset of studies in this review, we conducted a meta analysis summarizing 24-hour, day, and night standardized mean difference (hedge's g) in systolic and diastolic blood pressure during pregnancy for individuals later diagnosed with HDP and those without.

RESULTS

A total of 69 articles met all established criteria and were included in this systematic review, and a subgroup of studies that reported HDP outcomes (n=14) were included in the meta analysis. Out of the 69 studies, 31 (45.61%) used 24-hour ABP devices that are not validated for pregnant individuals. Birthing individuals diagnosed with HDP had elevated 24-hour, day, and night systolic and diastolic blood pressure during second and third trimesters of pregnancy.

CONCLUSION

A noticeable gap exists in the utilization of validated 24-hour ABP devices for pregnant and postpartum populations. Variations exist regarding the timing of 24-hour ABP measurements, particularly across trimesters.

IMPLICATIONS FOR PRACTICE

24-hour ABP monitoring could serve as one of the tools to identify and manage pregnant individuals at risk of HDP and ultimately reverse the current trend in maternal mortality.

Review: Influence of 25(OH)D Blood Concentration and Supplementation during Pregnancy on Preeclampsia Development and Neonatal Outcomes

Briefly, 25-hydroxyvitamin D (25(OH)D) plays an essential role in embryogenesis and the course of intra- and postnatal periods and is crucially involved in the functioning of the mother-placenta-fetus system. The low quantity of 25(OH)D during pregnancy can lead to an elevated risk for preeclampsia occurrence. Despite the numerous studies on the association of 25(OH)D deficiency and preeclampsia development, the current research on this theme is contradictory. In this review, we summarize and analyze study data on the effects of 25(OH)D deficiency and supplementation on pregnancy, labor, and fetal and neonatal outcomes.
