Double Blind Clinical Trial

Dysbiosis may contribute to constipation and its symptoms, therefore probiotic administration could improve significantly gut health and functions. The aim of the study was to investigate the effects of a long-lasting administration of Lactobacillus reuteri DSM 17938 (LR DSM 17938) on symptoms and quality of life (QoL) score in patients with functional constipation (FC). 56 FC patients with normal colonic transit time and without anorectal disorders and pelvic floor dysfunctions completed the study. LR DSM 17938 was administered for 105 days in a randomised double-blind clinical trial (28 patients per arm). Individual and cumulative scores including the Constipaq, a modified Constipation Scoring System (CSS) that considers the patient assessment of constipation-QoL (PAC-QoL), were calculated during the preliminary visit (V0), at day 15 (end of the induction period with a LR DSM 17938 double dosage, 4×108 cfu), day 60 (intermediate evaluation) and day 105 (V4) after a standard dosage (2×108 cfu). At the end of treatment, the beneficial effect of LR DSM 17938 compared to placebo was significantly evident for symptoms related to gas content and dysbiosis (abdominal discomfort, pain and bloating), incomplete defecation and helps for defecation (P<0.05). At the end of the whole LR DSM 17938 treatment, a marked and positive effect on both the CSS single and the cumulative items was evident with the exception of unfruitful attempt and Bristol score. Present findings indicate that LR DSM 17938 has an effect on symptoms different from stool consistency, and they suggest that this probiotic can effectively be used in association therapy rather than as single-drug therapy in the management of FC.

The Mean

Background & Aims: There is a growing interest for the use of probiotics for chronic constipation. A recent randomized controlled trial (RCT) showed a positive effect of Lactobacillus reuteri (L. reuteri) on bowel movement frequency in infants with chronic constipation. The aim of the present study was to evaluate the effects of L. reuteri in adult patients with functional constipation.Methods: A double-blind, placebo RCT was conducted in 40 adults (18M/22F, 35±15 years) affected by functional constipation according to the Rome III criteria. Patients were randomly assigned to receive a supplementation of L. reuteri (DSM 17938), or matching placebo for 4 weeks. The increase of bowel movements/week was the primary outcome, while the improvement of stool consistency was the secondary outcome.Results: At week 4, the mean increase in bowel movements/week was 2.6 (SD±1.14, 95% CI:1.6-3.6) in the L. reuteri group and 1.0 (SD±1. 95% CI:0.12-1.88) in the placebo group (p=0.046). At the end of the treatment, the mean bowel movements/week was 5.28±1.93 in the L. reuteri group and 3.89±1.79 in the placebo group. There was a not significant difference in the stool consistency between the two groups.Conclusions: L. reuteri is more effective than the placebo in improving bowel movement frequency in adult patients with functional constipation as previously demonstrated in children, even if it seems to have no effect on stool consistency.

Potential Strategy

The infantile colic is one of the most common complaints in the infancy; however, limited therapeutic approaches are described in the literature. Recently probiotics have been suggested as a potential strategy in the treatment of infantile colic. We conducted this study to investigate the efficacy of probiotics in relieving colic symptoms in Iranian infants. This double-blind clinical trial was performed among 70 infants aged 3 to 16 weeks with the presumed diagnosis of infantile colic according to Wessel criteria who were breastfed or formula fed. They were assigned at random to receive Pedilact® (Bifidobacterium infantis, Lactobacillus reuteri, and Lactobacillus rhamnosus) (N=33) or placebo (N=32). Demographic data were recorded in the questionnaires at the beginning of the study. The number of daily episodes of crying and fussiness, number of weekly crying days, and duration of crying were separately analyzed on 7, 21, and 30th  days of investigation. Baseline demographic data showed no statistically significant difference between intervention and placebo groups. Infants given Pedilact® showed a significant reduction in daily episodes of crying, duration of crying, and the weekly number of crying days at the end of the treatment period compared with those receiving placebo (P=0.000). On 21th day of the study, daily episodes of fuss and crying (P=0.032) and duration of crying reduced significantly in the intervention group in comparison to the placebo group (P=0.000). Administration of Pedilact® drop significantly improved colic symptoms by reducing crying and fussing times in breastfed or formula fed in Iranian infants with colic. © 2019 Tehran University of Medical Sciences.

Selected strains of lactobacilli and bifidobacteria are known to ameliorate constipation-related symptoms and have previously shown efficacy on digestive health. In this clinical trial, the safety and effectiveness of a probiotic blend containing lactobacilli and bifidobacteria were evaluated in adults with self-reported bloating and functional constipation. Constipation was diagnosed by the Rome III criteria. A total of 156 adults were randomised into this double-blind and placebo-controlled trial. Participants consumed the combination of Lactobacillus acidophilus NCFM (1010 cfu), Lactobacillus paracasei Lpc-37 (2.5×109 cfu), Bifidobacterium animalis subsp. lactis strains Bl-04 (2.5×109 cfu), Bi-07 (2.5×109 cfu) and HN019 (1010 cfu) (n=78), or placebo (microcrystalline cellulose) (n=78) for two weeks. After treatment the following were measured: primary outcome of bloating and secondary outcomes of colonic transit time, bowel movement frequency, stool consistency, other gastrointestinal symptoms (flatulence, abdominal pain, and burbling), constipation-related questionnaires (PAC-SYM and PAC-QoL) and product satisfaction. Faecal recovery of consumed strains was determined. The enrolled population was defined as constipated, however, the initial bloating severity was lower than in previous similar studies. No clinically significant observations related to the safety of the product were reported. Product efficacy was not shown in the primary analysis for bloating nor for the secondary efficacy analyses. The placebo functioned similarly as the probiotic product. In post-hoc analysis, a statistically significant decrease in flatulence in favour of the probiotic group was observed; day 7 (intention-to-treat (ITT): P=0.0313; per-protocol (PP): 0.0253) and on day 14 (ITT: P=0.0116; PP: P=0.0102) as measured by area under the curve (AUC) analysis. The mean AUC of all symptoms decreased in favour of the probiotic group, indicating less digestive discomfort. The study was registered at the ISRCTN registry (ISRCTN41607808).

The Impact

Glucosamine (GLU) is a natural compound found in cartilage, and supplementation with glucosamine has been shown to improve joint heath and has been linked to reduced mortality rates. GLU is poorly absorbed and may exhibit functional properties in the gut. The purpose of this study was to examine the impact of glucosamine on gastrointestinal function as well as changes in fecal microbiota and metabolome. Healthy males (n = 6) and females (n = 5) (33.4 ± 7.7 years, 174.1 ± 12.0 cm, 76.5 ± 12.9 kg, 25.2 ± 3.1 kg/m2, n = 11) completed two supplementation protocols that each spanned three weeks separated by a washout period that lasted two weeks. In a randomized, double-blind, placebo-controlled, crossover fashion, participants ingested a daily dose of GLU hydrochloride (3000 mg GlucosaGreen®, TSI Group Ltd., USA) or maltodextrin placebo. Study participants completed bowel habit and gastrointestinal symptoms questionnaires in addition to providing a stool sample that was analyzed for fecal microbiota and metabolome at baseline and after the completion of each supplementation period. GLU significantly reduced stomach bloating and showed a trend towards reducing constipation and hard stools. Phylogenetic diversity (Faith’s PD) and proportions of Pseudomonadaceae, Peptococcaceae, and Bacillaceae were significantly reduced following GLU consumption. GLU supplementation significantly reduced individual, total branched-chain, and total amino acid excretion, with no glucosamine being detected in any of the fecal samples. GLU had no effect on fecal short-chain fatty acids levels. GLU supplementation provided functional gut health benefits and induced fecal microbiota and metabolome changes.
