Vitamin D did not get supplemented until the 14th week of pregnancyThis trial had 8 different treatment branches, but failed to report the results from each branchSubjects with moderate deficiency:* I1: 50,000IU oral D3 weekly for a total duration of 6 weeks.* 300,000 IU total* I2: 50,000IU oral D3 weekly for a total duration of 6 weeks and then were on monthly maintenance dose of 50,000IU D3 until delivery.* 450,000 IU total* I3: A single dose of intramuscular administration of 300,000IU D3.* I4: A single dose of intramuscular administration of 300,000IU vitD3 and then were on monthly maintenance dose of 50,000IU D3 until delivery.* 450,000 IU total* 50% > 20 ngSubjects with severe deficiency:* I5: 50,000IU of oral D3 weekly for a total duration of 12 weeks.* 600,000 IU total* I6: 50,000IU of oral D3 weekly for a total duration of 12 weeks and then were on monthly maintenance dose of 50,000IU D3 until delivery.* 750,000 IU total* I7: Intramuscular administration of 300,000IU D3; 2 doses for 6 weeks.* 600,000 IU total* I8: Intramuscular administration of 300,000IU D3; 2 doses for 6 weeks, followed by a monthly maintenance dose of 50,000IU vitD3 until delivery.* ~750,000 IU total* 53% > 20 ngAcross both? - only 2.3% > 30 ngClearly not enough vitamin DOther studies getting to 40 ng have used 6,400 daily for 200 days = 1,300,000 IU totalInjection is one of the many ways to quickly restore vitamin D levelsInjections: 1 if deficient, 2 if very deficient (300,000 IU)| | | || --- | --- | --- || | Reduction | 1. Needed To Screen/Treat || Pre-eclampsia | 60% | 11 women || Gestational diabetes mellitus | 50% | 50 women || Preterm delivery | 40% | 20 women |---Note: Probably would have gotten more benefit from Vitamin D if given same total dose twice a month rather than once a month* * Injection category listing has items along with related searches* Loading Dose of Vitamin D category listing has items along with related searches** * Monthly 120,000 IU Vitamin D plus daily Calcium was great during pregnancies – RCT Sept 2017* Response to 150,000 IU vitamin D once vs 5,000 IU daily – RCT May 2014* Note: 6,400 IU daily was found to be great during pregnancy by several other studies* Monthly dosing would need require at least 200,000 IU monthly to get same benefit as 6,400 IU daily--- 1.

CONTEXT:

Despite evidence on the association between hypovitaminosis D and adverse pregnancy outcomes and the positive impact of vitamin D supplementation, no evidence exists supporting a universal screening program in pregnancy as part of a routine prenatal care.

OBJECTIVE:

We aimed at determining the effectiveness of a prenatal screening program on optimizing 25-hydroxyvitamin D(25(OH)D) levels and preventing pregnancy complications. Also, to identify a safe regimen, we compared several regimens in a subgroup of vitamin D deficient pregnant women.

DESIGN:

Two cities of Masjed-Soleyman and Shushtar from Khuzestan province, Iran were selected as the screening and non-screening arms, respectively. Within the screening arm, a randomized controlled trial was conducted on 800 pregnant women.

SETTING: Health centers of Masjed-Soleyman and Shushtar cities.

PATIENTS OR PARTICIPANTS: Pregnant women aged 18-40 years.

INTERVENTION: Women with moderate(25(OH)D:10-20ng/ml) and severe(25(OH)D<10ng/ml) deficiency were randomly divided into 4 subgroups and received D3 until delivery.

MAIN OUTCOME MEASURE: Maternal concentration of 25(OH)D at delivery and rate of pregnancy complications.

RESULTS:

After supplementation, only 2% of the women in the non-screening site met the sufficiency level(>20ng/ml), versus 53% of the women in the screening site. Adverse pregnancy outcomes including pre-eclampsia, gestational diabetes mellitus and preterm delivery were decreased by 60,50 and 40% in the screening site. A D3 injection in addition to monthly 50,000IU maintenance therapy contributed the most to achievement of sufficient levels at delivery.

CONCLUSIONS:

Prenatal vitamin D screening and treatment program is an effective approach in detecting deficient women, improving 25(OH)D levels and decreasing pregnancy adverse outcomes.
