ACOG today issued a policy statement against the practice of vaginal seeding in cesarean deliveries, in absence of sufficient data on potential benefits associated with the procedure.

The new policy statement published in the November issue of Journal Obstetrics and Gynecology. Earlier Danish Society of Obstetrics and Gynecology has already issued a similar statement at the national meeting on 19 January 2017.

Vaginal seeding is practiced at cesarean birth and consists of transferring maternal vaginal fluid with a gauze or swab to mouth, nose, or skin of a newborn infant to inoculate him with maternal bacteria. 

This practice came into vogue following a dramatic rise in prevalence of childhood asthma, atopic disease, and other immune disorders that paralleled a steep increase in cesarean sections rate worldwide, which prevented the fetal natural colonization with maternal vaginal flora.

At present ACOG only endorse it as a part of research project in institutions under an approved protocol.

If a patient or her attended insist for the procedure, they should be fully informed about the lack of scientific data in favor of any potential benefits. They should be explained the risks associated with the procedure and the mother should be tested for infectious diseases and potentially pathogenic bacteria. Lab testing should be ordered for herpes simplex virus and cultures for group B streptococci, Chlamydia trachomatis, and Neisseria gonorrhea.

The discussion with the patient should always be documented in her medical records and take in presence of other gynecologist, family physician or pediatrician. In the event of neonatal infection or sepsis, they are at least aware of the procedure.

The relationship between breast feeding and childhood asthma and allergies remains uncertain, ACOG recommends exclusive breast feeding for the first six months of life as it has ‘multiple known benefits.’

More research is needed on the subject before the potential benefits of this procedure is documented. Till date, the only available research on vaginal seeding is the result of a small pilot study published in Nature Medicine that was able to document similarities between bacterial communities of infants delivered by cesarean section and undergone vaginal seeding and babies delivered vaginally.

The potential risks associated with practice of vaginal seeding (VS) in Cesarean Delivery outweighs the hypothetical benefits and consequently we do not recommend it at present says the national recommendations released by Danish Society of Obstetrics and Gynaecology at the national meeting on 19 January 2017.

The recommendation along with a commentary was published online 22 AUG 2017 in British Journal of Obstetrics and Gynecology.

“We could not identify any other national or international society that had systematically investigated the clinical approach to VS,” write Thor Haahr, MD, PhD, from the Department of Obstetrics and Gynaecology at the Institute for Clinical Medicine, Aarhus University Hospital, Skejby, Denmark.

The recommendations are aimed at providing fellow obstetricians and midwives with the basic information about VS so that it can be discussed with couples and families opting for it.

The recommendations state that:

Maternity wards should not take part in screening, guiding or encouraging women for Vaginal Seeding.

Vaginal seeding is contraindicated in infants born before 37 weeks, born to mothers who meet national criteria for group B streptococci(GBS) prophylaxis during delivery, situations in which the cesarean section is done to prevent vertical transmission of infection such as—primary vaginal herpes infection, HIV infection with HIV-RNA >50 copies/ml and any other situations in which the VS will cause potential harm to the fetus.

Parents who still wish to perform VS, can do so provided “it does not interfere with or delay other procedures.” They should be informed about insufficient evidence in favor of any potential benefit and should be provided with patient information booklet. They should also be educated about signs of infection in neonates should any infection occurs after the procedure.

Interest in VS sparked after Dominguez-Bello and colleagues published the results of their pilot study in 2016 stating that Neonatal colonization can be partially restored in cesarean born babies by VS.  Several other studies have since followed involving VS which stress the importance of more research and publications on this topic.

Microbirthing:The " Vaginal Seeding" is growing fad, but thin evidence concerns physicians!

Although, the risk associated with VS is very low, the immediate concern after VS is early onset neonatal sepsis (EOS) with Escherichia coli or GBS.

David A. Eschenbach, MD, from the Department of Obstetrics and Gynecology, University of Washington, Seattle raised several questions in his accompanying commentary that need to be addressed before VS becomes a routine practice.

His major concern was our current inability to identify that which vaginal bacteria/gut bacteria will produce potential benefit while minimizing the harm. Choosing between ‘harmful’ and ‘helpful’ bacteria is expensive procedure and it is here the cost -benefit analysis comes in.

"We simply are too far behind in knowledge to start this practice without heeding the Society's recommendations," he concluded.

The authors suggest that clinicians whose patients want to adopt the practice should be told about the risk involved and other ways of that have an effect on neonatal colonization, including early skin-to-skin contact, breast-feeding, and diet during pregnancy.

Eating your own placenta: CDC issues warning against this latest craze!

Courtesy: YouTube. 

Center for Disease Control(CDC) issued a warning in the weekly Morbidity and Mortality Weekly Report (MMWR) against consumption of placenta pills, after an Oregon infant recurrent illness was tied to maternal consumption of placenta pills.

Consumption of placenta in the form of pills or smoothies is called as Placentophagy and has become a recent trend, after it was touted by many celebrities to help mothers overcome postpartum depression, increase milk production and speeds up uterus involution, boosts energy, promotes skin elasticity, enhances maternal bonding and replenishes iron in the body.

In the Oregon case, after an uneventful labor and delivery in September 2016, the infant developed signs of respiratory distress and was admitted to NICU. Samples for Blood and cerebrospinal fluid (CSF) were obtained; presuming sepsis. CSF was negative but the blood tested positive for penicillin-sensitive, clindamycin-intermediate group B Streptococcus agalactiae (GBS). The infant made a full recovery after 11 days of treatment with ampicillin (200 mg/kg/day).

The infant was readmitted after 5 days to a second hospital and tested positive for late-onset group B Streptococcus agalactiae (GBS) bacteremia.

Digging deeper to unravel the mystery of infant’s recurrent infection, the doctors discovered that from the third postpartum day, the infant’s mother was consuming two capsules of her dehydrated placenta three times a day.

A physician at the birth hospital notified the authorities at the second hospital that the mother has requested a release of the placenta after delivery. The mother has already enlisted with a company that has agreed to turn the placenta into gelatin capsules after processing it. The company cleans, slices and dehydrates placentas at 115°F–160°F (46°C–71°C). The dried and powdered placenta is then filled into about 115 to 200 gel capsules.

The placenta capsules

One such company is placentapower which provides the entire package of collecting your placenta from place of labor to delivering the processed capsules to your doorstep for $250. Other services provided by the company includes placenta tincture, salve and prints. 

The three GBS isolates (one from each blood infection, and one from the placenta capsules) were indistinguishable by pulsed-field gel electrophoresis. Consumption of contaminated placenta capsules might have elevated maternal GBS intestinal and skin colonization, facilitating transfer to the infant.

No scientific evidence supports the benefits of consuming the afterbirth. Dr. Crystal Clark, assistant professor of psychiatry and behavioral sciences at Northwestern University Feinberg School of Medicine and a psychiatrist specializing in reproduction-related mood disorders at Northwestern’s Asher Center for the Study and Treatment of Depressive Disorders conducted a review of 10 current published research studies and found that no scientific evidence supports the benefits of consuming the afterbirth.

The study was published June 4 in Archives of Women's Mental Health.

A 2016 study from the University of Nevada Las Vegas, published in Journal of Midwifery and Women’s Health concluded, “ Encapsulated placenta supplementation neither significantly improves nor impairs postpartum maternal iron status for women consuming the RDA of dietary iron during pregnancy and lactation.”

The CDC MMWR reports warning says, “The placenta encapsulation process does not per se eradicate infectious pathogens; thus, placenta capsule ingestion should be avoided. In cases of maternal GBS colonization, chorioamnionitis, or early-onset neonatal GBS infection, ingestion of capsules containing contaminated placenta could heighten maternal colonization, thereby increasing an infant’s risk for late-onset neonatal GBS infection. Clinicians should inquire about a history of placenta ingestion in cases of late-onset GBS infection and educate mothers interested in placenta encapsulation about the potential risks.”

Ground placenta is used in traditional Chinese medicine since years. In North America, the first documented evidence of Placentophagy is around 1970s. Midwives and birthing doulas also prepare the capsules of placenta.
