A Randomized Trial of Maternal Docosahexaenoic Acid Supplementation to Reduce Inflammation in Extremely Preterm Infants. Keywords Leukocyte infiltration, cytokine release, and the resulting inflammation contribute to the initiation of parturition, and the maternal response to this inflammation provides protective effects for both mother and infant [1,2]. Here's what you need to know. Several markers have been identified as indicative of inflammation in pregnancy [20,21,22] and some of the most significant are the focus of this investigation: the Receptor for Advanced Glycation End Products (specifically, soluble and extracellular forms, sRAGE), Interleukin (IL)-6, IL-1, Tumor Necrosis Factor alpha (TNF) and Interferon gamma (IFN). In our randomized, multi-site, double-blind superiority trial using a Bayesian adaptive design, we demonstrated that 1000 mg/day of docosahexaenoic acid (DHA) was superior to 200 mg/day in preventing both early preterm birth (less than 34 weeks' gestation) and preterm birth (less than 37 weeks' gestation). the contents by NLM or the National Institutes of Health. At least 5000 burn-in and 40,000 Markov chain draws were performed. If you do decide to include this amount of DHA in your supplemental routine, you should consult with your healthcare provider first. They're also included in some prenatal vitamins.

The ORIP and ADORE trials are the first to study EPB as a primary outcome and ADOREis the first study that compared a standard amount of DHA in many prenatal supplements to a higher dose, states Dr. Carlson. During pregnancy, women need at least 200 milligrams daily of this powerful omega-3 fatty acid to support the development of baby's brain, eyes and nervous system. If you're taking a prenatal multivitamin or want to complement your prenatal vitamin with some healthy omega-3s, it'sa really good idea to see if it contains a solid amount (more on that later) of docosahexaenoic acid (DHA). Omega-3 Fish Oil is recommended during pregnancy. (2008). Assessment of DHA on reducing early preterm birth: The ADORE randomized controlled trial protocol. Participants received an algal source of DHA. Her work has appeared in Womens Health, Prevention, Self, Glamour, and more. One interpretation of these findings is that IL-6 plays a significant role in regulating the parturition process and that higher levels support uterine quiescence until term gestational age. Higher dose docosahexaenoic acid supplementation during pregnancy and early preterm birth: a randomised, double-blind, adaptive-design superiority trial. ; Writingreview & editing, A.Q.K., A.R.B., S.A.S., E.A.D., B.J.G., S.E.C., K.M.R. Early preterm birth means that a baby is born before their due datespecifically, before 34 weeks of pregnancy. doi: 10.1111/j.1471-0528.2006.01120.x. Preterm delivery is defined as giving birth at less than 37 weeks, with the due date being at 40 weeks. Background paper on fat and fatty acid requirements during pregnancy and lactation.

Early preterm births may be dramatically decreased with DHA supplements, with a dose of 1000 mg more effective for pregnant women with low DHA levels than the 200 mg found in some prenatal supplements, according to the study published in EClinicalMedicine, a clinical journal of The Lancet. Beam AL, Fried I, Palmer N, et al. TNF and INF are not causally associated with the parturition process but are elevated with inflammatory conditions associated with pregnancy such as chorioamnionitis [40], exposure to environmental pollutants [41], preterm rupture of membranes [41], preeclampsia, gestational diabetes [22], and preterm birth [20]. to a prenatal supplement of 1000 mg DHA daily would have a lower rate of EPB than those assigned to 200 mg daily.

Others have speculated that the microinflammation and oxidative stress that occur during parturition create ligands for RAGE and sRAGE and that available sRAGE then acts as a decoy receptor to prevent deleterious responses. Inflammation in Complicated Pregnancy and Its Outcome. . Makrides M, Best K, Yelland L, et al. 2023 Jun 17;21(1):394. doi: 10.1186/s12967-023-04239-8. 2014;65(1):49-80. doi: 10.1159/000365767. 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. (To put that number into perspective, a serving of walnuts has 2,600 milligrams of ALA7. For women with high DHA status at the beginning of the study, the rate of early preterm births was around 1% for both 1,000 mg of DHA/day and 200 mg of DHA/day. 5, 6 Both maternal DHA intake and circulating DHA concentrations are important determinan. FOIA Cochrane Database Syst Rev. 2023 Jun 17;21(1):394. doi: 10.1186/s12967-023-04239-8. government site. A total of 1,100 pregnant women were enrolled and randomized to receive either the high dose or low dose of DHA. Higher TNF levels at delivery were associated with an increased probability of a shorter gestational length and a greater probability of preterm birth (<37 weeks) (Table 3). Pregnancy and parturition involve extensive changes in the maternal immune system. EPA and DHA can be synthesized in the body from dietary sources of ALA, but the conversion rate is very low (and variable), says Jessica Cording, M.S., R.D., CDN, registered dietitian and author of The Little Book of Game Changers. CONTINUE TO SITE. 2022 Nov;186:102495. doi: 10.1016/j.plefa.2022.102495. 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%. The physiological events that surround preterm parturition remain elusive but previous data support the finding that maternal inflammation is a primary contributor to preterm birth. Biomarkers for a histological chorioamnionitis diagnosis in pregnant women with or without group B streptococcus infection: A case-control study. Early and late preterm birth rates in participants adherent to randomly assigned high dose docosahexaenoic acid (DHA) supplementation in pregnancy. 8600 Rockville Pike Partner with DSM for access to our broad portfolio of science-backed products, customized solutions, and expert services aimed at reliably supporting your entire product life cycle, from concept to consumer. Christifano DN, Crawford SA, Lee G, Brown AR, Camargo JT, Kerling EH, Gajewski BJ, Valentine CJ, Gustafson KM, DeFranco EA, Carlson SE. Given the important role of inflammation in the preterm parturition cascade, this study tested a secondary hypothesis in this Phase 3 clinical trial: that supplementation with 1000 mg per day of DHA would be superior to 200 mg per day in regulating inflammatory responses and would provide a mechanism by which DHA prevents preterm birth. This is well above the recommended 200 mg dose., Many pregnancies would benefit from more supplementalDHAthan in most prenatal supplements,study author Susan E. Carlson, PhD, professor of nutrition in the department of dietetics and nutrition at the University of Kansas Medical Center, tells Verywell. You can find DHA in certain prenatal multivitamins or as a separate, stand-alone omega-3 supplement, too. In the binary analyses of preterm birth, higher levels of both enrollment and delivery IL-6 and lower enrollment levels of TNF were associated with an increased probability of experiencing a birth at less than 37 weeks (pp = 0.87, 0.85, and pp = 0.03, respectively).

June 21, 2021 Higher-dose DHA in pregnancy tied to fewer early preterm births (HealthDay)Supplementation with a higher dose of docosahexaenoic acid (DHA) versus the standard prenatal dose. Solutions to address consumers' health and lifestyle needs. (34) . Consequently, the function of sRAGE depends upon the extracellular milieu and the severity of the inflammatory responses. A prospective study to evaluate these relationships is needed. In 2018, a Cochrane Review concluded that EPB could be significantly reduced nearly by half when pregnant women received omega-3 long-chain polyunsaturated fatty acids (LCPUFAs) including DHA through food or supplements, compared to women who did not receive any omega-3 LCPUFAssupplement.8However, the Review includedsupplementation witheicosapentaenoic acid (EPA), another omega-3 LCPUFA, and it did not identify an optimal dose or type of omega-3 LCPUFAs for consumption.8.

Oliver E.A., Buhimschi C.S., Dulay A.T., Baumbusch M.A., Abdel-Razeq S.S., Lee S.Y., Zhao G., Jing S., Pettker C.M., Buhimschi I.A. In our randomized, multi-site, double-blind superiority trial using a Bayesian adaptive design, we demonstrated that 1000 mg/day of docosahexaenoic acid (DHA) was superior to 200 mg/day in preventing both early preterm birth (less than 34 weeks' gestation) and preterm birth (less than 37 weeks' gestation). -, Valentine C.J., Dingess K.A., Kleiman J., Morrow A.L., Rogers L.K. The parent study had 1032 births for which sRAGE and cytokine measurements could have been collected and analyzed. Docosahexaenoic acid (DHA) intake estimated from a 7-question survey identifies pregnancies most likely to benefit from high-dose DHA supplementation. ); ude.cmuk@ikswejagb (B.J.G. 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).

DHA is a metabolically active fatty acid that has been extensively studied in the context of nutrition, neurodevelopment, and immunology [3,6,7,8,9,10]. Other variables included in the analyses were smoking history (before or during pregnancy), maternal race and ethnicity (non-Hispanic Black versus other race and ethnicity), history of preeclampsia, and enrollment BMI (>30 versus 30 kg/m2). Red blood cell DHA was measured from maternal and cord blood plasma at delivery and EQ status was calculated. Himmelfarb J., Phinney S., Ikizler T.A., Kane J., McMonagle E., Miller G. Gamma-tocopherol and docosahexaenoic acid decrease inflammation in dialysis patients. NCHS Data Brief. The risk comes from NOT eating fish or taking fish oil. TNF is a proinflammatory cytokine that promotes protection from bacterial and viral infections but has also been associated with medical complications of pregnancy such as diabetes and preeclampsia [20,22,40]. Raucci A., Cugusi S., Antonelli A., Barabino S.M., Monti L., Bierhaus A., Reiss K., Saftig P., Bianchi M.E. (scarlson@kumc.edu) or B.J.G. Milk, cheese, yogurt, sardines, dark green leafy vegetables. Young points out that DHA is found mainly in seafood, listing the following as the best sources: You can also get DHA from algae and a small amount from eggs enriched with omega-3s, Young points out. A pioneering new study establishes that supplementation with docosahexaenoic acid (DHA), an omega-3 fatty acid, during pregnancy at 1,000 mg per day significantly reduces the risk of early preterm birth (EPB), or birth < 34 weeks gestation.

Carlson SE, Gajewski BJ, Valentine CJ, et al. Dr. Carlson is also interested in improving education for pregnant women around the topic of prenatal nutrition, knowing that awareness is key to changing behavior. 2018;11:CD003402. However, since 80% of Americans dont eat recommended amounts of seafood, it is safe to say that many people likely do not have adequate levels of the nutrient. It is not clear whether taking dietary supplements containing EPA and DHA during pregnancy or breastfeeding affects a baby's health or development. Another study in healthy people found that daily . Kaempf J, Morris M, Steffen E, Wang L, Dunn M. Continued improvement in morbidity reduction in extremely premature infants. Higher INF levels at delivery were associated with the probability of an earlier gestational age at birth [20,22,39] (Table 3). Clinicians could consider prescribing 1000 mg DHA daily during pregnancy to reduce EPB in women with low DHA status if they are able to screen for DHA. sRAGE induces human monocyte survival and differentiation. A new study shows that pregnant women who are low in DHA may reduce their risk of early preterm birth when they supplement with 1,000 milligrams (mg) of DHA omega-3 fatty acid per day. Cytokines in the perinatal periodPart II. Getting Enough Omega-3s in Your Diet May Help You Live Longer 8600 Rockville Pike The immune markers, sRAGE and cytokines, were measured in participants that provided both enrollment and delivery samples for testing. Christifano DN, Crawford SA, Lee G, Brown AR, Camargo JT, Kerling EH, Gajewski BJ, Valentine CJ, Gustafson KM, DeFranco EA, Carlson SE. Immunomodulation by omega-3 fatty acids. 2023 Apr 12;21(1):256. doi: 10.1186/s12967-023-04083-w. Christifano DN, Chollet-Hinton L, Mathis NB, Gajewski BJ, Carlson SE, Colombo J, Gustafson KM. and L.K.R. The trial found that a womans baseline DHA status, which is highly related to her DHA intake from diet or a prenatal supplement, made a difference. In general, ALA is found in plant-based foods, while fatty fish, the algae they consume, and shellfish (e.g., oysters, mussels, lobsters, and crab) are the best sources of EPA and DHA. Differences in the probability of a higher dose of DHA (1000 mg per day) to prevent preterm birth compared to a lower dose (200 mg per day) were noted in the parent trial between women with high (>6% of RBC total fatty acids) baseline DHA levels versus low baseline DHA (<6% of RBC total fatty acids) levels. For infants born prematurely, prior to 37.0 weeks gestation, 26.3% (31/118) were missing sRAGE and cytokine data due to missing or unusable blood samples while 10.8% (99/914) of term deliveries were missing sRAGE and cytokine data. The site is secure. Cochrane Database Syst Rev. At least 5000 burn-in and 40,000 Markov chain draws were performed. Sincemany prenatal supplementsalreadyprovide approximately 200 mg/day of DHA,Dr. Carlson and colleagues elected not to utilize a placebo when designing the study. Primary efficacy analysis by group Bayesian posterior probability (pp) =0.91 for less early, Efficacy analysis in participants with low DHA status at enrolment (red blood cell, MeSH Parturition is associated with leukocyte infiltration and the release of cytokines to initiate labor [1,2].

The determinant role of IL-6 in the establishment of inflammation leading to spontaneous preterm birth. Flenady V, Reinebrant HE, Liley HG, Tambimuttu EG, Papatsonis DN. The primary outcome was EPB by dose and by enrolment DHA status (low/high). Funding: Speaking of clinical consensus, doctors generally recommend9 that pregnant individuals consume 200 milligrams of DHA a day, says Greves. Rather, they contain ALA, a fatty acid that does not offer the same benefit to the fetus. Omega-3 fatty acids are known as healthy fats and play important roles in human health. While Dr. Carlson reflects on the importance of the learnings from the ADORE trial, she also acknowledges that the trial findings provide a call to action.
