DOI: 10.1001/jama.2010.1507 Molloy A, et al. Of the pregnant people who had a high DHA status at the beginning of the trial, the rate of early preterm birth was 1.3%. Simmonds LA, Sullivan TR, Skubisz M, et al. This data may be interpreted to mean that supplementing with 1000 mg per day of DHA supports a more robust production of sRAGE and the capacity to reduce inflammation in pregnancy. Changes in circulating levels of carboxymethyllysine, soluble receptor for advanced glycation end products (sRAGE), and inflammation markers in women during normal pregnancy. Docosahexaenoic acid, or DHA, is a specific omega-3 fatty acid that humans need to obtain from food or supplements, as they cannot make this key nutrient in adequate amounts. The site is secure. First for Women published a story examining sinus infections and whether or not they are contagious. Understanding whether these mechanisms may contribute to the prevention of preterm birth associated with higher-dose DHA supplementation is therefore important to understand. The relative changes (delivery concentrations minus enrollment concentrations) in sRAGE, IL-6, IL-1, TNF, or IFN were analyzed with the treatment group alone as a predictor (Table 4). 2014;65(1):49-80. doi: 10.1159/000365767.

Cytokine Growth Factor Rev. Normal Bayesian models also quantified the effect of the sRAGE and cytokine levels at enrollment and delivery on the outcome of gestational age at birth in weeks while accounting for the confounding variables (treatment group, maternal race and ethnicity, BMI group, history of preeclampsia, DHA at enrollment, and smoking history (before or during pregnancy)).

A total of 1,100 pregnant women were enrolled and randomized to receive either the high dose or low dose of DHA. This further decrease in sRAGE concentration is likely due to the events associated with the onset of preterm labor (or parturition) which are often associated with inflammation and similar inflammatory mediators that interact with available sRAGE.

This study represents a milestone in the scientific communitys understanding of the impact of DHA on pregnancyduration. Currently it is recommended for pregnant women to take 200 mg daily of DHA during pregnancy, which is included in most prenatal vitamins, says Emily DeFranco, DO, professor and director of maternal-fetal medicine in the University of Cincinnati College of Medicine Department of Obstetrics and Gynecology. These data provide a proposed mechanistic explanation of how a higher dose of DHA during pregnancy provides immunomodulatory regulation in the initiation of parturition by influencing sRAGE and IL-6 levels, which may explain its ability to reduce the risk of preterm birth.

A soluble form of the receptor for advanced glycation endproducts (RAGE) is produced by proteolytic cleavage of the membrane-bound form by the sheddase a disintegrin and metalloprotease 10 (ADAM10). All samples were stored at 80 C for the measurement of sRAGE and inflammatory cytokines. Pregnancy and parturition involve extensive changes in the maternal immune system. The goal of this secondary study is to compare the effects of 1000 mg/day versus 200 mg/day on maternal inflammation, a possible mechanism by which DHA may prevent preterm birth.

Fish Oil During Pregnancy - OmegaVia Pregnant people with low DHA status at the beginning of the trial who received a 1,000 mg supplement of DHA experienced half the rate of early preterm birth (2% of births) compared to those who received 200 mg of DHA (4%). Furthermore, some epidemiological evidence links higher IL-6 levels to preterm birth and suggests that IL-6 levels may be a biomarker of early delivery [22]. Maternal DHA supplementation has demonstrated efficacy in preventing preterm birth, but the optimal dose required to achieve a protective effect has not been clearly defined and the mechanism of action has not been identified [4]. New clinical evidence confirms a higher-dose of DHA reduces early preterm birth. Finally, smaller changes in sRAGE were associated with higher-dose DHA supplementation (1000 mg per day) compared to a standard lower dose (200 mg per day, Table 4) and a greater probability that higher-dose DHA supplementation is better than a lower dose in maintaining sRAGE levels during pregnancy.
