Multi-Center, Double-Blind, Randomized, Placebo-Controlled, Parallel-Group Study to Evaluate the Benefit of the Probiotic Bifidobacterium infantis 35624 in Non-Patients With Symptoms of Abdominal Discomfort and Bloating. | LitMetric
Objectives: Bifidobacterium infantis 35624 is a probiotic that is used often in patients with irritable bowel syndrome (IBS). Non-patients with bowel symptoms may differ from patients with IBS in the impact of their bowel symptoms on illness severity, healthcare and treatment seeking behavior. The aim of this study is to assess the efficacy of B. infantis 35624 (10 c.f.u. per day) for the relief of abdominal discomfort and bloating in a non-patient population.
Methods: A double-blind, randomized, placebo-controlled, parallel study with a 2-week placebo run-in phase followed by a 4-week intervention phase was conducted at ten clinical centers (USA). Subjects were recruited from the general population by advertisement. The study randomized 302 subjects who experienced abdominal discomfort and bloating ≥2-times per week for at least three months but have not seen a physician or received prescribed medication for their symptoms in the past 12 months. Subjects were assessed for pre- to post-intervention changes in symptom severity (on a 6-point Likert scale; 0=none, 5=very severe) and frequency (symptoms-free days).
Results: A total of 275 subjects (mean age 42 years, 79% female, 74% Caucasian) provided evaluable data. Overall mean severity scores at baseline were 2.4 for abdominal discomfort and 2.5 for bloating with no significant differences between the placebo and probiotic groups. Both groups showed significant (P<0.05) improvement in abdominal discomfort and bloating scores over the 4-week intervention period. Mean severity symptom scores at the end of intervention showed no significant differences between the probiotic and the placebo groups in either abdominal discomfort or bloating (P>0.3). The frequency of abdominal bloating-free days was greater in the B. infantis 35624 group compared to the placebo group (P<0.05). Both regimens were well tolerated.
Conclusions: Unlike previous clinical studies in patients with IBS, B. infantis 35624 did not show a significant improvement in the mean severity of symptoms of abdominal discomfort and bloating in a non-patient population. This may be explained by the high placebo effect and the lower impact of functional bowel symptoms in the non-patient population.
Human milk provides essential nutrients for infants but also consists of human milk oligosaccharides (HMOs), which are resistant to digestion by the infant. Bifidobacteria are among the first colonizers, providing various health benefits for the host. This is largely facilitated by their ability to efficiently metabolize HMOs in a species-specific way.

Introduction And Aim: In recent years, probiotics have been used in functional gastrointestinal disorders, including chronic constipation (CC). The effect of Bifidobacterium infantis strain 35624 on the gut microbiota of CC patients has not been previously studied. Our aim was to analyze the fecal microbiota of constipated patients, before and after consuming a single-strain probiotic (B.
The aim of the study is to investigate the anti-tumor effect of Bifidobacterium infantis 35624 in a xenograft model in BALB/c mice injected with 4T1 cells as a support for chemotherapeutic treatments of doxorubicin in vivo. The MTT assay was used to determine the cytotoxicity of doxorubicin against cancer cells, and apoptosis was analyzed by using flow cytometry. 4T1 cells (2 × 10 cells/mouse) were injected to BALB/c mice, and mice were fed with/without gavage B.
