Developing Precision Microbiota-Based Cocktail Modification Therapy to Delay the Progression of Parkinson's Disease (PD) - Use Preclinical Human Trials to Confirm the Impact of the Optimal "Probiotic Y7, Tryptophan and Branched-chain Amino Acid" Cocktail Formula on Early Stage PD Patients

Preclinical human trials will be utilized to validate the research direction, followed by clinical trials to assess the impact of a cocktail formula product containing the optimal probiotic Y7 combined metabolites on motor, cognitive, and non-motor functions in early Parkinson's disease patients. The study aims to recruit 120 patients (stage 1-3) and employ a two-arm, randomized controlled trial (RCT) design, dividing subjects into intervention and control groups for a 12 weeks trial period. Commercial development will be contingent upon the clinical trial outcomes, evaluating whether the product offers clinical benefits such as delaying Parkinson's disease progression in motor, cognitive, and non-motor functions. Additionally, a personalized and precise prognosis prediction model for Parkinson's disease will be established. This model will gather comprehensive clinical data, including motor function assessments (functional tests, UPDRS), biochemical markers, questionnaire responses, and genotype data (TPM array), as well as metabolite and microbial data. Through integrated analysis of this biological information using machine learning techniques, a personalized and accurate prognosis prediction model for Parkinson's disease will be developed. This model will predict the disease status of PD patients 12 weeks later, accounting for factors such as cocktail therapy. The results will empower PD patients to understand their individual disease progression and treatment prognosis, enabling them to prepare accordingly. Moreover, this model will aid researchers in identifying patient profiles more likely to benefit from treatment, thereby enhancing the evaluation of the efficacy and applicability of cocktail therapy.

Probiotic Intervention on the Development of Allergic Diseases in Infants Exposed to Antibiotics Early in Life

Early antibiotic exposure is an important environmental factor that disrupts the establishment of the infant gut microbiota and leads to microbial dysbiosis. Accumulating epidemiological evidence indicates that exposure to antibiotics early in life (including both prenatal and postnatal periods) is significantly associated with an increased risk of allergic diseases in childhood. As live microorganisms, probiotics hold potential as a preventive strategy against allergies due to their ability to stabilize the intestinal barrier and regulate immune balance (e.g., promoting Th1/Th2 balance, inducing regulatory T cells, and increasing sIgA secretion). However, current studies have mostly focused on general or high-risk infant populations. For the specific high-risk subgroup that has already been exposed to antibiotics early in life, high-quality randomized controlled trial evidence is still lacking regarding whether probiotic intervention can effectively reduce the incidence of allergies and whether it exerts its effects by reshaping the gut microbiota and metabolites disrupted by antibiotics. This study focuses on breastfed infants who received antibiotics during the early postnatal period (within 30 days after birth) and aims to investigate the effect of a probiotic mixture containing Bifidobacterium longum subsp. infantis R0033, Lactobacillus helveticus R0052, and Bifidobacterium bifidum R0071 on the development of allergic diseases after antibiotic exposure.

Efficacy of Symprove Probiotics in Coeliac Disease

Coeliac Disease (CD) is a lifelong autoimmune condition where eating gluten (a protein found in wheat, barley, and rye) causes damage to the small intestine. It affects around 1 in 100 people. Most individuals feel better and their gut heals after switching to a strict gluten-free diet. However, up to 1 in 5 people with coeliac disease continue to experience unpleasant gut symptoms-such as bloating, pain, and diarrhoea-despite following the diet and having a healed intestine. These ongoing symptoms can be very distressing and impact daily life. This study investigates whether a food supplement called Symprove, a probiotic drink containing live good bacteria, can help relieve these ongoing symptoms. Scientists believe that in some people with coeliac disease, the community of bacteria in the gut (called the microbiota) becomes unbalanced, even after going gluten-free. This imbalance (known as dysbiosis) may lead to inflammation, irritation, and symptoms similar to irritable bowel syndrome (IBS). The aim of this study is to test whether Symprove can help correct this imbalance and reduce symptoms. Participants will take Symprove daily and their symptoms, quality of life, and gut bacteria (measured from stool samples) will be monitored over time. The study hopes to answer three key questions: Can Symprove reduce gut symptoms in people with coeliac disease who are in remission? Does it work by restoring a healthy balance of gut bacteria? Are people with more severe imbalance (dysbiosis) more likely to have symptoms? If successful, this research could offer a safe, non-drug option to improve life for coeliac patients who continue to suffer symptoms despite avoiding gluten. It could also help suggest that gut bacteria play a role in ongoing symptoms and are a target for future treatment.

Multi-strain Probiotic Effects on Self-Reported Constipation

Constipation is a prevalent gastrointestinal condition. Beyond simple lifestyle measures (e.g. increasing fibre intake, hydration, levels of exercise), medical therapies are available for management. However, a sizeable number of sufferers are dissatisfied with drug treatments (either over-the-counter or prescribed), meaning there is an unmet need for alternative therapeutic strategies. Pre, pro- and synbiotics have emerged as one alternative treatment, and a growing body of evidence now supports their use in a proportion of individuals with mild constipation. However, it is currently not possible to predict which individuals may benefit. A better understanding of an individuals' symptoms and underlying pathophysiology may allow for more targeted treatment. The multistrain live bacterial food product (probiotic) being tested contains billions of live and active bacteria that has been shown to improve symptoms in the irritable bowel syndrome (IBS: which is 'constipation-predominant' in many). Notably, improvements ('completely resolved' or 'some positive difference') in bowel habit satisfaction, abdominal pain, bloating and urgency, as well as on quality of life have been shown after 4 or more weeks of this probiotc. This study aims to have 20 participants with self-reported constipation to assess improvements in constipation symptoms, quality of life and measures of gut function.

Impact of Probiotics on Gut Microbiome During Antibiotic Prophylaxis in Elective Orthopedic Surgery

This study aims to evaluate whether probiotics can help maintain a healthy gut microbiome in patients receiving prophylactic antibiotics during elective orthopedic surgery. Antibiotics, while effective in preventing infections, can disrupt the balance of gut bacteria, leading to dysbiosis. The study hypothesizes that the use of probiotics during the perioperative period can prevent or reduce this disruption, supporting gut health and overall well-being. The research seeks to answer whether combining probiotics with routine antibiotic prophylaxis can preserve gut microbiome balance and improve patient outcomes.

Lactobacillus Reuteri Strain Combination in Children Treated With PPI

Probiotics might be of help in preventing dysbiosis and emergence of SIBO. Gastrus consisted of a mixture of two human strains of L. Reuteri DSM 17938 and ATCC PTA 6475; the first have extensive data supporting its use in gastric infections (18) however, it lacks the anti-inflammatory properties that have been provided by L. Reuteri DSM ATCC PTA 6475 that has excellent acid resistance and has strong anti-inflammatory properties (19); for these reasons, Gastrus is the best candidate for this indication.

Multimodal Image Technologies Investigate the Role and Mechanism of Probiotics in Improving RBD with Parkinson's Disease

Rapid eye movement sleep behavior disorder (RBD) is important non-movement feature, and also the important risk factor of Parkinson's disease (PD). In our previous work, we found that the movement features and RBD of PD patients improved after taking probiotics. The later was not reported before and the mechanism not clear. To investigate its role and mechanism, we plan to enroll patients of PD-RBD, idiopathic RBD, and healthy control, collect data of multimodal image technology before and after probiotic treatment,including resting state functional MRI,1H-MRS,123I-MIBG; analyze these data with clinical features, including UPDRS -III score, RBD-HK score , as well as the bacteria abundance and level of glutamate,GABA in blood and stool. Then, construct PD mouse model by fecal transplantation of PD patient, give or not give mouse probiotics treatment, and detect the level of glutamate, GABA, and so on, as well as α-synuclein of each brain area of each group, to explore the role and mechanism of probiotics in improving RBD and movement disorder of PD.
