ACIP recommends two options for pertussis vaccination. Janyne Althaus, MD Dr. Because the fetus derives vitamin D exclusively from maternal stores, a low level in a pregnant woman can have serious repercussions. Should you test your patients for deficiency? What numbers should you use?

And how do you treat a low vitamin D level? In pregnancy, these issues become critical because there are not one but two patients to consider. Despite the lack of clear guidelines, there is sufficient evidence to suggest that you should at least consider monitoring the vitamin D status of your pregnant patients. Fetal needs for vitamin D increase during the latter half of pregnancy, when bone growth and ossification are most prominent.

Vitamin D travels to the fetus by passive transfer, and the fetus is entirely dependent on maternal stores. The vitamin D level in breast milk also correlates with the maternal serum level, and a low vitamin D level in breast milk can exert a harmful effect on a newborn.

For years, vitamin D was discussed solely in relation to bone metabolism and absorption, and deficiency states were the purview of endocrinologists and gynecologists who treated menopausal patients at risk of osteoporosis. Recent studies demonstrate that vitamin D plays a role in multiple endocrine systems.

Indeed, vitamin D may be more correctly considered a hormone because it is a substance produced by one organ skin that travels through the bloodstream to target end organs.

Vitamin D receptors have been found in bone, breast, brain, colon, muscle, and pancreatic tissues. Not only does vitamin D affect bone metabolism, it also modulates immune responses and even glucose metabolism. Some of the confusion surrounding vitamin D concerns the units used to measure and discuss it. Compounding the confusion, vitamin D in supplement form can be written in two different measurements—using micrograms or international units.

Does the vitamin D level affect pregnancy outcomes? Research into vitamin D and its effects on pregnancy is still in its infancy, but many intriguing associations have been noted. For example, lower levels of vitamin D have been associated with increased rates of cesarean delivery, 3 bacterial vaginosis, 4 and preeclampsia, 5 as well as less efficient glucose metabolism.

There is biological plausibility for vitamin D to play a role in pregnancy outcomes, given the presence of receptors in gestational tissues. Vitamin D receptors in uterine muscle could affect contractile strength, and vitamin D has been shown to have immunomodulatory effects, thereby potentially protecting the host from infection. Very few foods contain a large amount of vitamin D, and the few that do herring, cod liver oil are not standard fare. Even fortified foods such as milk lack a substantial amount.

Jump to navigation. It is not clear if vitamin D supplementation, alone or in combination with calcium or other vitamins and minerals, during pregnancy have benefits or harms to the mother or her offspring. Vitamin D is essential for human health, particularly bone, muscle contraction, nerve conduction, and general cellular function.

Low concentrations of blood vitamin D in pregnant women have been associated with pregnancy complications. It is thought that additional vitamin D through supplementation during pregnancy might be needed to protect against pregnancy complications. What was studied in the review? This is an update of a review that was first published in and subsequently updated in This review evaluated the effect of supplementation with vitamin D alone or in combination with other micronutrients for women during pregnancy in comparison to placebo or no intervention , irrespective of dose, duration or time of commencement of supplementation or type of supplementation oral or by injection.

We searched for evidence July and found 30 trials involving women for inclusion in this update. Evidence from 22 trials involving pregnant women suggest that supplementation with vitamin D alone during pregnancy probably reduces the risk of pre-eclampsia, gestational diabetes, and the risk of having a baby with low birthweight compared to placebo or no intervention and may make little or no difference in the risk of having a preterm birth.

It may reduce the risk of maternal adverse events, such as severe postpartum haemorrhage, although it should be noted that this result was unexpected and based on a single trial. Evidence from nine trials involving pregnant women suggest that supplementation with vitamin D and calcium probably reduces the risk for pre-eclampsia but may increase the risk of preterm birth. This slight potential harm warrants consideration in women receiving calcium supplementation as part of antenatal care.

Evidence from one study involving pregnant women suggest that supplementation with vitamin D plus other nutrients may make little or no difference in the risk of most outcomes evaluated.

What does this mean? Supplementing pregnant women with vitamin D alone probably reduces the risk of pre-eclampsia, gestational diabetes, low birthweight and the risk of severe postpartum haemorrhage.

Supplementing pregnant women with vitamin D and other nutrients may make little or no difference in the risk of preterm birth or low birthweight less than g and the effects for gestational diabetes and maternal adverse events are unclear.

Additional rigorous high quality and larger randomised trials are required to evaluate the effects of vitamin D supplementation in pregnancy, particularly in relation to the risk of maternal adverse events. We included 30 trials women across three separate comparisons.

Our GRADE assessments ranged from moderate to very low, with downgrading decisions based on limitations in study design, imprecision and indirectness. Supplementing pregnant women with vitamin D alone probably reduces the risk of pre-eclampsia, gestational diabetes, low birthweight and may reduce the risk of severe postpartum haemorrhage.

Vitamin D supplementation during pregnancy may be needed to protect against adverse pregnancy outcomes. This is an update of a review that was first published in and then in To examine whether vitamin D supplementation alone or in combination with calcium or other vitamins and minerals given to women during pregnancy can safely improve maternal and neonatal outcomes.

Abstracts were included if they had enough information to extract the data. A total of 22 trials involving pregnant women were included in this comparison; 19 trials were assessed as having low-to-moderate risk of bias for most domains and three trials were assessed as having high risk of bias for most domains. Supplementation with vitamin D alone during pregnancy probably reduces the risk of pre-eclampsia risk ratio RR 0.

In terms of maternal adverse events , vitamin D supplementation may reduce the risk of severe postpartum haemorrhage RR 0.

There were no cases of hypercalcaemia 1 trial , women, low-certainty evidence , and we are very uncertain as to whether vitamin D increases or decreases the risk of nephritic syndrome RR 0. However, given the scarcity of data in general for maternal adverse events, no firm conclusions can be drawn.

Nine trials involving pregnant women were included in this comparison; three trials were assessed as having low risk of bias for allocation and blinding , four trials were assessed as having high risk of bias and two had some components having a low risk , high risk , or unclear risk.

Supplementation with vitamin D and calcium during pregnancy probably reduces the risk of pre-eclampsia RR 0. The effect of the intervention is uncertain on gestational diabetes RR 0.

No trial in this comparison reported on maternal adverse events. One trial in participants was included in this comparison; it was assessed as having low risk of bias. Pre-eclampsia was not assessed. It is unclear whether it makes any difference to the risk of gestational diabetes RR 0.

Is vitamin D supplementation beneficial or harmful for women during pregnancy? What is the issue? Why is this important? What evidence did we find? Data on maternal adverse events were lacking in most trials.
