What the trial was testing
The trial enrolled 54 patients with atopic dermatitis. The study was sponsored by National Institute of Allergy and Infectious Diseases (NIAID) and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was an early-stage trial — researchers are still confirming safety and getting an early look at how well the treatment works. Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
The treatment reduced harmful bacteria on the skin and was safe with fewer eczema-related side effects.
Nature medicine · 2021 · NCT03151148
These findings — that people who got the bacteria treatment had fewer eczema-related problems — were published in the Nature medicine and represent the headline result of the study.
Researchers tracked outcomes across 54 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with atopic dermatitis, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
This was an early-stage study and the treatment is not yet FDA-approved. The bacteria therapy showed promise by fighting the germs that worsen eczema, but larger studies are needed. Ask your doctor about open trials or related approved options for managing atopic dermatitis.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

Preventive Effect of a Dietary Supplement With Two Probiotic Limosilactobacillus Reuteri Strains on Excessive Crying and Colic in Healthy Newborns.
This study aims to demonstrate that a dietary supplement, which contains two strains of the probiotic L. reuteri is safe, well tolerated and able to reduce the incidence of colic and excessive crying/fussiness in healthy infants. Additionally, the study aims to investigate if children with this probiotic supplement have better stool characteristics and a more beneficial composition of the fecal and skin flora than children given a placebo during the first 3 months of life.
Identification of Cutaneous and Blood Biomarkers Predictive of Response to Systemic Treatments During Chronic Inflammatory Skin Diseases
Chronic inflammatory skin diseases constitute a heterogeneous group of pathologies. They affect the skin but also other organs (joints, lungs, muscles, etc.). Their prognosis and response to treatments is extremely variable. The discovery of prognosis factors will help to precisely guide the treatment regimen and its intensification based on individual markers. The identification of new therapeutic targets is essential to develop new innovative treatments for inflammatory skin diseases. The main objective is to identify new cellular or molecular prognostic factors associated with treatment response at 1 year in inflammatory skin diseases. The secondary objectives are a better understanding of the pathophysiology of chronic inflammatory skin diseases, the identification of new cellular, molecular and microbiological prognostic factors associated with the clinical state after 10 years of evolution and the identification of prognostic markers of drug toxicity.
