This study aims to test the hypothesis that vitamin D deficiency can influence long‐chain polyunsaturated fatty acid metabolism through alterations in the one‐carbon cycle. Wistar rats (n = 8 per group) were given either a control (1,000 IU D3/kg diet) or a vitamin D deficient (VDD) (0 IU D3/kg diet) diet from pre‐pregnancy to delivery. On day 20 of gestation, pregnant female rats were delivered by C‐section to collect placenta and blood. VDD group demonstrated high serum parathyroid hormone, low serum phosphate, low plasma folate, higher plasma homocysteine, and higher plasma malondialdehyde levels (P < 0.05 for all) as compared to control. Lower protein levels of placental cystathionine‐β‐synthase enzyme (P < 0.05) were observed in the VDD group as compared to control. VDD group demonstrated higher placental mRNA levels of the enzymes phospholipase A2 and cyclooxygenase‐2 (P < 0.05 for both) as compared to control. Protein levels of the enzymes phospholipase A2 and cyclooxygenase‐2 were lower (P < 0.05 for both) in the VDD group as compared to the control group. The ratio of thromboxane B2 and 6‐keto prostaglandin F1α in serum was higher (P < 0.05) in the VDD group as compared to control; although the serum levels of 6‐keto prostaglandin F1α and thromboxane B2 were similar in both the groups. Our findings suggest that increased oxidative stress due to maternal vitamin D deficiency results in the imbalance between the vasoconstrictor (thromboxane B2) and vasodilator (6‐keto prostaglandin F1α) eicosanoids, which may lead to endothelial dysfunction and poor pregnancy outcome. © 2019 BioFactors, 45 (4):548–555, 2019

ObjectiveTo determine the effect of maternal status in (plasma and red blood cell) folate, vitamin B12, homocysteine, and vitamin D, as well as their interaction with MTHFR (C677T and A1298C) and MTRR A66G polymorphisms, on maternal plasma docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), and arachidonic acid (ARA) levels and the risk of neural tube defects (NTDs).MethodsARA, EPA, and DHA composition was assessed using capillary gas chromatography.ResultsARA and DHA levels were higher in controls than in case mothers for low plasma folate status. For low red blood cell folate status, DHA levels were higher in controls than in case mothers. For high homocysteine levels, ARA and DHA levels were higher in controls than in case mothers. NTD mothers had lower EPA and DHA levels for low vitamin B12 levels. NTD mothers had lower DHA levels for low vitamin D levels. For low plasma folate status, DHA levels in the MTHFR C677T gene and ARA and EPA levels in MTHFR A1298C gene were different among the three genotypes in case mothers. DHA levels in the MTHFR C677T gene were different among the three genotypes in case mothers for both low and high homocysteine levels. For low vitamin B12 levels, ARA and DHA levels were different among the three genotypes of the MTHFR C677T gene in case mothers. In the MTHFR C677T gene, ARA and DHA levels were different among the three genotypes in case mothers for low vitamin D levels.ConclusionsMore advanced research is required to verify a suitable biochemical parameter status in relation to the genotypes in pregnant women.

Objectives: Approximately 40% of boys with X-linked adrenoleukodystrophy (ALD) develop inflammatory demyelinating brain lesions (cerebral ALD, cALD) and are at risk for death or severe disability. Risk factors for cALD are poorly understood. Our objective was to evaluate whether vitamin D status, which influences immune function, is associated with risk for cALD. Methods: We used two independent cohorts to assess whether low vitamin D status is correlated with cALD. We used complementary proxies for vitamin D status: plasma 25-hydroxyvitamin D levels and latitude. In our first cohort, we measured 25-hydroxyvitamin D in biobanked plasma samples from ALD boys with initially normal brain MRIs followed at two expert centers. In a second cohort, we measured latitude (using home ZIP code) among ALD boys identified in a national administrative database (PHIS) covering 51 US pediatric hospitals. We used logistic regression models to estimate the odds of developing cALD in each cohort. Results: In the first cohort, we identified 20 ALD boys with a total of plasma sample timepoints who met inclusion criteria; 50% (n = 10) subsequently developed cALD. Average 25-hydroxyvitamin D levels were lower among boys who developed cALD than those who did not (median 28.9 vs 36.6 ng/ml); p = 0.019. For each 10 ng/mL decrease in 25-hydroxyvitamin D, the odds ratio for developing cALD was 6.94; p = 0.044. In the second cohort, we identified ALD boys across 28 states; 57% of boys (n = 132) developed cALD. Each 2°i ncrease in latitude conferred an odds ratio of 1.17 (95% confidence interval, 1.01, 1.35); p = 0.036 for developing cALD. Conclusions: Using independent cohorts, we found that ALD boys with lower pre-morbid plasma levels of 25-hydroxyvitamin D, or more northerly latitude of residence, were more likely to develop cALD. These findings offer complementary lines of evidence that vitamin D and/or ultraviolet light exposure influence cALD risk.
