Probiotic mixture in patients after Helicobacter pylori eradication: a real-life experience.

BACKGROUND: Eradication for Helicobacter pylori usually induces digestive dysbiosis that, in turn, elicits symptoms. Consequently, probiotic supplementation may counterbalance the disturbed microbiota after this procedure. So, probiotics may restore microbiota homeostasis quickly relieve complaints. METHODS: The current study evaluated the efficacy and safety of Abivisor®, a food supplement containing Lacticaseibacillus rhamnosus LR06 (3 billion living cells), Lactiplantibacillus pentosus LPS01(100 million living cells), Lactiplantibacillus plantarum LP01 (1 billion living cells), and N-acetyl cysteine (60 mg). Patients were randomized into two groups (2:1). Group A took one stick/daily for 60 days after eradication. Group B was considered as control. Patients were evaluated at baseline (T0) and after 15 (T1), 30 (T2), and 60 (T3) days. The severity of digestive symptoms was measured by patients using a Visual Analog Scale. The percentage of patients with each symptom was also evaluated. RESULTS: Abivisor® has significantly and progressively diminished intestinal symptoms' presence and severity at T1, T2, and even more at T3. Accordingly, the percentage of symptomatic patients diminished more rapidly and significantly in group A than in B. All patients well tolerated the food supplement. CONCLUSIONS: The present study suggests that Abivisor® may be an effective and safe therapeutic option for managing patients undergoing H. pylori eradication.

Probiotics for managing patients after bowel preparation for colonoscopy: an interventional, double-arm, open, randomized, multi-center, and national study (COLONSTUDY).

BACKGROUND: Bowel preparation (BP) for colonoscopy induces significant changes in gut microbiota, causing dysbiosis that, in turn, elicits intestinal symptoms. Consequently, probiotics may counterbalance the disturbed microbiota after BP. So, probiotics may restore microbiota homeostasis. METHODS: The current study evaluated the efficacy and safety of Abincol®, an oral nutraceutical containing a probiotic mixture with Lactobacillus plantarum LP01 (1 billion living cells), Lactobacillus lactis subspecies cremoris LLC02 (800 millions living cells), and Lactobacillus delbrueckii LDD01 (200 millions living cells), Patients were randomized in two groups (2:1). Group A took one stick/daily for four weeks after colonoscopy. Group B was considered as control. Patients were evaluated at baseline (T0) and after one (T1), two (T2), and four (T3) weeks. The severity of symptoms was measured by patients using a Visual Analog Scale. RESULTS: Abincol® significantly diminished the presence and the severity of intestinal symptoms at T2 and even more at T3. All patients well tolerated the probiotic mixture. CONCLUSIONS: The present study suggests that Abincol® may be considered an effective and safe therapeutic option in managing patients undergoing BP. The course should last one month.

Gastric protection in cardiological practice: an Italian survey on the prescriptive attitude.

BACKGROUND: Gastric protection is commonly considered in patients who use medications able to damage gastric mucosa, mainly NSAIDs, antiplatelets, and anticoagulants. Therefore, cardiologists may frequently prescribe drugs to protect the stomach from damaging medications. The present survey investigated the attitude toward using gastric protection by a panel of Italian cardiologists. METHODS: A self-administered questionnaire included three sections concerning practical problems on this issue in clinical practice facing patients with cardiological disorders. The questionnaire was administered in three successive months. RESULTS: Ninety Italian cardiologists completed the questionnaire. They all consider gastric protection, mainly when prescribing potentially noxious medications. Usually, cardiologists prescribe proton pump inhibitors (PPIs) in 60% of their patients. Alginates and mucosal protectors are less considered. As a rule, cardiologists request investigations if the initial treatment fails. Moreover, the safety issue is carefully assessed. Furthermore, this survey experience significantly affected the approach to managing patients who require gastric protection. The participants carefully considered the prescriptive appropriateness of gastric protectors, mainly concerning the PPIs use. Consequently, PPIs were discontinued when inappropriate. A new medical device with triple action (antacid, mucosal protectors, and anti-reflux) contributed to this new attitude. CONCLUSIONS: The present survey underscored that the appropriateness in prescribing gastric protectors is clinically relevant. In addition, a longitudinal survey experience contributed to change the practical approach by highlighting the prescriptive appropriateness of PPIs, and using a new medical device with multiple gastroprotective activities.

Evaluation of main functional dyspepsia symptoms after probiotic administration in patients receiving conventional pharmacological therapies.

OBJECTIVE: Postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS) are the two main forms of functional dyspepsia (FD). Probiotics are a promising therapy for FD, but current data remains heterogeneous. This work aims to evaluate a probiotic combination of Lacticaseibacillus rhamnosus LR04 (DSM 16605), Lactiplantibacillus pentosus LPS01 (DSM 21980), Lactiplantibacillus plantarum LP01 (LMG P-21021), and Lactobacillus delbrueckii subsp. delbruekii LDD01 (DMS 22106), alone or together with other pharmacological therapies, for clinical improvement of symptoms associated with FD. METHODS: Patients with FD were enrolled and divided into two groups: PDS and EPS. Probiotic alone or combined with prokinetics, antacids, or proton-pump-inhibitors were administered for 30 days. A progressive-score scale was used to evaluate symptoms in all patients at the beginning of the trial and at 15 days after the end of treatment. RESULTS: A cohort of 2676 patients were enrolled (1 357 with PDS; 1 319 with EPS). All patients showed significant improvements in dyspeptic symptoms following treatment. In patients with PDS, probiotic alone resulted in the lowest prevalence of symptoms following treatment, while patients with EPS showed no clear between-treatment differences. CONCLUSIONS: Dyspeptic symptoms were reduced following treatment in all patients.

Efficacy of a New Ocular Surface Modulator in Restoring Epithelial Changes in an In Vitro Model of Dry Eye Syndrome.

PURPOSE: So far tear substitutes have demonstrated a limited role in restoring ocular surface damage in dry eye syndrome (DES). The aim of this study was to assess the efficacy of a new ocular surface modulator in an in vitro model of human corneal epithelium (HCE) damaged by severe osmotic stress mirroring the features of dry eye conditions. METHODS: A reconstructed HCE model challenged by the introduction of sorbitol in the culture medium for 16 h was used to induce an inflammatory pathway and to impair the tight junctions integrity determining a severe modification of the superficial layer ultrastructure. At the end of the overnight stress period in the treated HCE series, 30 µl of the ocular surface modulator (T-LysYal, Sildeha, Switzerland) and of hyaluronic acid (HA) in the control HCE series were applied for 24 h. The following parameters were quantified: scanning electron microscopy (SEM), trans-epithelial electrical resistance (TEER), immunofluorescence analysis of integrin ß1 (ITG-ß1), mRNA expression of Cyclin D-1 (CCND1), and ITG-ß1. RESULTS: In the positive control after the osmotic stress the HCE surface damage was visible at the ultrastructural level with loss of cell-cell interconnections, intercellular matrix destruction, and TEER reduction. After 24 h of treatment with T-LysYal, HCE showed a significant improvement of the ultrastructural morphological organization and increased expression of ITG-ß1 at the tissue level when compared to positive and control series. A significant increase of mRNA expression for ITG-ß1 and CCND1 was shown in the HA-treated cells compared to T-LysYal. TEER measurement showed a significant reduction in all groups after 16 h without modifications after the treatment period. CONCLUSIONS: This study has shown the possibility of a new class of agents denominated ocular surface modulators to restore corneal cells damaged by dry eye conditions. Further in vivo studies are certainly necessary to confirm these results.
