Vitamin D did not get supplemented until the 14th week of pregnancy
This trial had 8 different treatment branches, but failed to report the results from each branch
Subjects 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 ng

Subjects 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 ng

Across both? - only 2.3% > 30 ng
Clearly not enough vitamin D
Other studies getting to 40 ng have used 6,400 daily for 200 days = 1,300,000 IU total

Injection is one of the many ways to quickly restore vitamin D levels
Injections: 1 if deficient, 2 if very deficient (300,000 IU)

Reduction# Needed
To Screen/Treat
Pre-eclampsia60%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

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.
