Obesity is a major health concern in the Deep South resulting in a growing number of metabolic disorders that strain the resources of our healthcare system. Obesity is recognized as a major risk factor for asthma. The Centers for Disease Control and Prevention (CDC) has stated "obesity is associated significantly with the development of asthma, worsening asthma symptoms, and poor asthma control. This leads to increased medication use and hospitalizations." Variations in the airway microbiome are correlated with the risk for development of asthma, and populations of different bacteria vary by phenotype amongst severe asthmatics . Proteobacteria are found in greater proportion in asthmatic subjects relative to healthy controls (37% vs 15%) while non-asthmatic subjects have a relative abundance of Firmicutes (47% vs 63%) and Actinobacteria (10% vs 14%) compared to those with asthma . Amongst those with asthma, obese asthmatic subjects have a relative abundance of Bacteroides (54%) and Firmicutes (26%). Notably, both phyla are part of the gastrointestinal microbiome, suggesting inoculation through gastroesophageal reflux which may be more common in obese individuals. Asthmatics identified as having improvement in their asthma control following treatment with inhaled corticosteroids appear to have a greater relative abundance of Actinobacteria (79.8%) in their airways relative to other asthmatics. Actinobacteria have been associated with the production of anti-inflammatory proteins and are speculated to be involved in increasing steroid responsiveness. Other studies have demonstrated that oral administration of probiotics, including Bifidobacterium species within the phyla Actinobacteria, lead to reduced Th2 cytokine production and eosinophilic inflammation, along with promotion of Regulatory T-cell (Treg) populations within the airway. We hypothesize that administration of over the counter oral probiotics containing Actinobacteria (Bifidobacterium) to obese asthmatic subjects will result in decreased airway inflammation and better asthma control by immune modulation.
Background: Urinary tract infections (UTIs) are a common and costly cause of doctor visits for children. Frequent UTIs trigger kidney damage that leads to serious diseases like high blood pressure, pregnancy complications, and kidney failure. Treating UTIs with preventative antibiotics has not shown improvement of the risk of these diseases, and contributes to the growing public health issue of antibiotic resistant bacteria. Bacteria that cause UTIs originate from the bowel. In an effort to reduce the number of UTIs, investigators want to exchange the bacteria living in our bowels for a more harmless variety. Hypothesis and specific aims: Investigators hypothesize a probiotic comprised of a probiotic bacteria will change the bowel bacteria, thereby reducing the numbers of infection-causing bacteria, thus reducing frequency of UTIs in healthy patients with recurrent UTIs and those patients with urinary tract problems that require use of catheters to empty their bladders. Aim 1: Investigators plan to challenge infection-causing bacteria like Pseudomonas species, Enterococcus species, and Klebsiella species to live in the same environment with the probiotic bacteria to see how the numbers of each bacteria change. Aim 2: Investigators will culture bacteria that live on urinary catheters and then challenge them to live in the same environment as the probiotic bacteria. Potential Impact: This novel treatment prevents UTIs by exchanging a patient's bowel bacteria for a harmless bacteria and reduces the use of antibiotics overall in the community.
Multi-center, randomized, placebo controlled, partially blinded trial comparing the safety and efficacy of fecal microbiota transplantation versus placebo both delivered by rectal enema in subjects 18 years of age or older with recurrent Clostridium difficile Associated Disease (CDAD). 162 male or female subjects will be enrolled in the study. Enrolled subjects will be randomized at each site to receive either FMT by enema or placebo by enema in a 2:1 ratio. Study duration is 3 years, subject participation duration is approximately 1 year. The primary study objectives are: 1) to evaluate the safety of FMT(s) delivered by enema vs. placebo delivered by enema and 2) to determine efficacy of FMT delivered by enema vs. placebo delivered by enema.
The goal of this study is to evaluate the role of probiotics in the treatment of pediatric NAFLD by evaluating for steatosis and fibrosis with a Fibroscan machine. This will be done by performing a fibroscan during each visit and comparing patients' ALT at various intervals. This is an important study as current pediatric guidelines only recommend lifestyle modifications for the treatment of NAFLD and the use of ALT and sonogram to assess improvement as standard of care. Investigators hypothesized that treatment with a probiotic will demonstrate an improvement in NAFLD as assessed by a fibroscan of liver which is good for the monitoring of steatosis and fibrosis. Additionally, analysis of fecal microbiome results may offer insight into targeted therapy in the future.
The investigators will study the efficacy and side effect profile of LGG, a probiotic, in pediatric patients with acute gastroenteritis.
A double-blind randomized controlled trial comparing iron plus vitamin C plus probiotic (lactobacillus plantarum 299) to iron plus vitamin C plus placebo in correcting the iron deficiency in children with Restless leg syndrome (RLS) and iron deficiency. One hundred children with diagnosis of RLS will be recruited over a two- year period.
This randomized phase II clinical trial studies probiotic supplementation in preventing treatment-related diarrhea in patients with cancer undergoing chemotherapy. Probiotics may help prevent diarrhea caused by treatment with chemotherapy.
The purpose of this study is to determine if twice or three times daily supplementation of Lactobacillus acidophilus MPH734 (Lacto-FreedomTM, or LF), for one week, affects acute (immediate), subacute (7 days), and post-treatment discontinuation (30-, 60-, and 90- day) lactose metabolism, gastrointestinal symptoms, and clinical markers of inflammation and safety compared to a placebo.
Purpose: This is a pilot randomized double-blind placebo controlled trial of anticholinergic or beta-3 agonist medication with or without concomitant probiotic therapy in women initiating medication therapy for overactive bladder (OAB). The aims of this study are to: 1. Explore how concomitant probiotic therapy influences response to medication for OAB in a randomized controlled trial 2. Investigate whether 4 weeks of probiotic therapy alters the urinary microbiome 3. Assess for predictors of response to therapy Participants: Women 18 years of age or older presenting to the Division of Urogynecology and Reconstructive Pelvic Surgery clinic with OAB/UUI or UUI-predominant mixed incontinence who desire nonsurgical therapy will be eligible for participation. Procedures (methods): The study will be conducted over a two-year time frame and the primary outcome will be subjective improvement in symptoms as assessed by the Patient Global Impression of Improvement (PGI-I) validated questionnaire at 4 weeks after initiating anticholinergic or beta-3 agonist medication and study drug. The study aims to recruit up to 140 participants randomized in a 1:1 ratio to either concomitant probiotic or placebo medication.
This study evaluates the effects of probiotic consumption on inflammatory outcomes and measures of gut health. Participants will be given yogurt with probiotics for one period and yogurt without probiotics for another, with a break in between. These periods will occur in random order.
This study aims to assess the impact of a chronic dietary intervention (8 weeks) with probiotics, specifically Fermented Milk Product with Probiotic (FMPP), on the mood of individuals with Major Depressive Disorder (MDD) refractory to standard antidepressant therapy, and its association with changes in intestinal microbiota and markers of inflammation.
Background: Atopic dermatitis (AD) is a skin disease also called eczema. It is common in children and sometimes gets better on its own. However, chronic AD may cause asthma, food allergies, eye infections, and sleep problems. The cause of AD might be related to bacteria that live on the skin. Researchers want to see if introducing bacteria, R mucosa, from healthy skin onto the skin of someone with AD helps treat the disease. Objective: To test the safety and activity of R mucosa for treating AD. Eligibility: Part 1: People ages 18 and older with AD Part 2: Children ages 3-17 with AD Design: Participants will be screened with: Medical history Physical exam Examination of their AD Blood and urine tests At the baseline visit, participants will have blood tests and photos taken of their skin. They will get a supply of R mucosa and a memory aid to track their doses and record how they are feeling. Part 2 participants guardians will complete questionnaires about their child s AD. Part 1 participants will spray R mucosa on their arm twice per week for 6 weeks. Part 2 guardians will spray it on their child s arm twice per week for 16 weeks. Participants will have follow-up visits to repeat some baseline tests and review their memory aid: Part 1: Six weeks after the baseline visit Part 2: Four times over 16 weeks; then 2 or 3 times for 1 year Participants will be called or emailed to discuss how they are feeling: Part 1: About 30 days after their last visit Part 2: About every 10 days between visits
This randomized clinical trial studies how well probiotic yogurt supplement works in reducing diarrhea in patients with kidney cancer that has spread from the primary site to other places in the body (metastatic) and that are being treated with vascular endothelial growth factor-tyrosine kinase inhibitor therapy. Studying samples of blood and stool from patients who eat probiotic yogurt and those who avoid probiotic yogurt may help doctors plan better treatment.
