Could Research into the Microbiome of Babies Prevent Lifelong Allergies Later in Life?

Microbiome of Babies

Recent research into the microbiome of babies has revealed a potential breakthrough in preventing lifelong allergies. The human body is home to trillions of microorganisms, collectively known as the microbiome, which play a crucial role in immune development. Scientists have discovered that early exposure to diverse microbial communities can help train the immune system and reduce the risk of developing allergies later in life. This groundbreaking finding opens up new possibilities for interventions that could significantly impact public health.

The first few months of life are critical for establishing and developing a healthy microbiome. Studies have shown that babies born through cesarean section or those not breastfed may miss out on essential microbes found in vaginal birth and breast milk, respectively. These differences can lead to an altered composition of gut bacteria, linked to an increased risk of allergies.

The Research

A new research effort calls on parents and their babies to participate in a groundbreaking study that aims to prevent allergic diseases before they begin. Certain infants are more susceptible to developing conditions like atopic dermatitis, food allergies, asthma, and hay fever. These allergic diseases can profoundly impact a child’s life and often persist into adulthood. Studies have shown that having a family history of these diseases increases the risk of a child developing them. Unfortunately, there are currently no approved treatments available to prevent allergic diseases from occurring.

The importance of this research effort cannot be overstated. Allergic diseases not only impact the quality of life for those affected but also place a significant burden on healthcare systems worldwide. By focusing on prevention rather than treatment after symptoms develop, researchers hope to reduce the prevalence of these conditions in future generations greatly.

New research is underway at various research sites across the United States, investigating the potential prevention of allergies by enhancing a baby’s gut microbiome. This groundbreaking study focuses on introducing beneficial bacteria found in infants with robust gut microbiomes to determine if it can effectively reduce the risk of developing allergies later in life. With an increasing number of individuals affected by allergies worldwide, this research could hold significant promise for future generations.

The gut microbiome is crucial in maintaining overall health and well-being, impacting various bodily functions, including digestion, immunity, and metabolism. Studies have shown that individuals with diverse and healthy gut microbiomes tend to have lower rates of allergic conditions. Researchers aim to leverage this knowledge by introducing specific strains of beneficial bacteria into babies’ digestive systems to promote a balanced and robust gut microbiome from an early age.

The ADORED study

The ADORED study is an exciting new research endeavor that seeks to delve deeper into the intricate relationship between gut health and allergic diseases. With a focus on strengthening gut immunity, researchers hope to prevent the development of allergies among newborns with a family history of allergic diseases. By administering a live biotherapeutic at an early stage of life, they aim to explore whether it can effectively halt the onset of these conditions.

Allergic diseases, such as asthma and eczema, have become increasingly prevalent in recent years, affecting millions worldwide. The ADORED study recognizes the urgent need for preventative measures and aims to address this issue head-on. By intervening during infancy when the immune system is still developing, researchers believe they may be able to reshape gut immunity and ultimately reduce the risk of developing allergies later in life.

Several studies have shed light on the connection between the absence of specific microbes in the gut and the development of allergic diseases. Conditions such as atopic dermatitis, food allergy, asthma, and allergic rhinitis have all been linked to a lack of certain microbes in the gastrointestinal tract. This newfound understanding has paved the way for researchers to explore potential preventive measures against these conditions.

One study aiming to tackle this issue head-on is the ADORED Study. The primary objective of this research project is to assess whether STMC-103H, an experimental probiotic-based treatment comprising a collection of beneficial microbes, can effectively prevent newborns from acquiring allergic diseases in their early years. By introducing this consortium of commensal microbes into their systems from birth, scientists hope to modify and enhance their gut microbiota, potentially reducing the risk of developing allergies later in life.

Siolta Therapeutics, led by CEO Dr. Nikole Kimes, is taking a groundbreaking approach to address the underlying cause of disease and provide early intervention for multiple allergic diseases that share a common immune dysregulation. This novel approach targets the root cause rather than merely treating symptoms, aiming to alleviate suffering and improve the lives of countless individuals.

Allergic diseases have become an increasing burden on global health systems and economies. The United States alone bears a significant portion of this burden, with millions of people affected by asthma, rhinitis, eczema, food allergies, and other related conditions. The traditional approach of managing these diseases through symptom relief has proven inadequate in providing long-term solutions or preventing their progression.

Siolta Therapeutics’ mission is ambitious but crucially needed in today’s healthcare landscape.


A groundbreaking study is underway to determine if the treatment known as STMC-103H can potentially prevent atopic dermatitis (eczema), food allergy, asthma, and allergic rhinitis (hay fever). Unlike over-the-counter probiotics, STMC-103H is an investigational live bacterial product (LBP) regulated by the FDA as a drug. This means it must go through rigorous clinical trials to demonstrate both safety and effectiveness before it can be used for widespread treatment.

STMC-103H is composed of naturally occurring bacteria crucial in maintaining human gut health. As research increasingly points towards the importance of a healthy gut microbiome in preventing various diseases and allergies, scientists are intrigued by the potential of this innovative treatment. The manufacturing process for LBPs ensures the highest levels of quality to meet strict regulatory standards, giving researchers confidence in its potential benefits.

Eligibility requirements

Families interested in enrolling their newborn in the study should visit the study website or to confirm they meet the eligibility criteria to participate, as listed below: 

·         The child’s birth parent(s) or legal representative is 18 or older.

·         Child is ≤ 14 days of age. If the child’s mother is in her 2nd or 3rd trimester, the clinical site would like to obtain her parental consent for her child’s participation. This consent will be reconfirmed upon the child’s birth.

·         The child’s biological mother, biological father, and/or any full sibling has one or more conditions: asthma, atopic dermatitis (allergic eczema), food allergy, or allergic rhinitis (hay fever, nasal allergies).

·         The baby has not been given any probiotics (including formula containing probiotics) since the time of birth, and the child’s birth parent(s) or legal guardian do not plan to give probiotics to the baby during the entire study.

·         The baby is generally healthy, was not born prematurely (no less than 35 weeks gestation), and had an average birth weight (no less than 2.5 kg/5.5 lbs and no more than 4.5 kg/9.9 lbs). If a newborn meets the eligibility criteria, they should contact one of the participating clinical trial sites directly for more information.
