Objective: Patients with symptomatic uncomplicated diverticular disease (SUDD) may have a disrupted gut microbiota. However, current data are from small sample studies, and reported associations vary widely across studies. We aimed to profile the fecal microbiota in SUDD patients enrolled in primary care., Methods: A retrospective study was conducted in SUDD ( N  = 72) and asymptomatic diverticulosis (AD) ( N  = 30), the latter serving as a control group., Results: No significant differences in alpha and beta diversity were found between SUDD and AD, but SUDD was discriminated by a higher relative abundance of the family Streptococcaceae and the genera Alistipes , Agathobacter , and Butyricimonas . Interestingly, the gut microbiota of SUDD patients stratified by the severity of abdominal pain [according to the visual analog scale (VAS)]. In particular, higher diversity and health-associated taxa (such as Bifidobacterium , Eubacterium coprostanoligenes group, and Dorea ) characterized mild (VAS score 1-3) SUDD, Proteobacteria , Veillonellaceae and Blautia moderate (VAS score 4-7) SUDD, and Prevotellaceae and Megasphaera severe (VAS score 8-10) SUDD., Conclusion: Our analysis suggests that specific taxa may be related to SUDD, but the associations vary depending on the severity of abdominal pain. In addition to advancing our ecological understanding of this complex disease, our findings may pave the way for the incorporation of gut microbiota profiling into clinical practice to aid patient management, including stratification and treatment., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Although FD may affect up to 10% of the general population, the therapy for FD is not standard. Recently, ginger-based food supplements have been proposed in order to restore FD symptoms. Our aim was to assess the efficacy of a new nutraceutical formulation containing extract of gingerol and thymus as a possible natural treatment in managing the symptoms of functional dyspepsia (FD)., Methods: We retrospectively analyzed the efficacy and safety profiles of a nutraceutical formulation containing Zingiber officinalis root extract and a standardized Thymus extract. It was administered as 1 ml/day twice a day for 90 days. Patients were assessed at baseline and after 1, 2 and 3 months of treatment, following a month of pharmacological washout by completing a questionnaire reporting the trend of the following symptoms: epigastric pain, epigastric heaviness, early satiety, belching, and regurgitation. Every symptom was assessed by a Visual Analogic Scale (VAS), ranging from 0= absence to 10= maximal severity., Results: We enrolled 272 patients (99 males and 173 females; median IQR age 49.5, 36-64 yrs). Obesity (BMI>30) was present in 28 (12.5%) patients; smokers were 83 (30.5%); and comorbidities were present in 107 (39.3%) patients. Improvement of symptom scores during treatment and one month after its suspension was extremely significant (p<0.000)., Conclusion: This large study found that nutraceutical formulation could be one of the tools for an empirical approach to treat patients with FD, especially when a non-conventional drug treatment is preferable for the patient and considered suitable by the physician., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)
