RESUMEN

Introdução: A segurança e eficácia do uso de medicamentos durante a lactação são preocupações para mães e profissionais de saúde. Esta pesquisa analisa as orientações das bulas de medicamentos comumente prescritos para dispepsia e constipação, que visa fornecer informações essenciais para orientar as decisões terapêuticas durante esse período crucial da maternidade. Objetivos: Analisar as informações das bulas sobre contraindicações de medicamentos para dispepsia e constipação durante a amamentação, verificando se estão de acordo com as evidências científicas. Métodos: Medicamentos para dispepsia e constipação foram selecionados de acordo com a classificação da Anatomical Therapeutic Chemical (ATC) e o registro ativo no Brasil. A presença de contraindicações para o uso de medicamentos nas bulas do profissional de saúde e do paciente foi comparada com as informações contidas no manual técnico do Ministério da Saúde, Medicamentos e Leite Materno, LactMed, UptoDate, Micromedex, Documento Científico da Sociedade Brasileira de Pediatria e Reprotox. Resultados: Nenhuma informação sobre o uso durante a amamentação foi encontrada em 20,0 e 24,3% das bulas para dispepsia e constipação, respectivamente. A concordância entre as bulas dos medicamentos para dispepsia e as fontes consultadas foi baixa (27,2% das bulas contraindicavam o medicamento na lactação, enquanto nas fontes o percentual de contraindicação variou de 0 a 8,3%). Com relação a medicamentos para constipação, 26,3% das bulas os contraindicavam, enquanto nas fontes o percentual variou de 0 a 4,8%. Conclusões: O estudo mostrou que pelo menos duas em cada dez bulas para dispepsia e constipação não fornecem informações adequadas sobre o uso desses medicamentos em lactentes, e também que houve baixa concordância entre o texto das bulas e as fontes de referência quanto à compatibilidade do medicamento com a amamentação.

Introduction: The safety and effectiveness of medication use during lactation are concerns for mothers and healthcare professionals. This research analyzes the instructions on the leaflets of medications commonly prescribed for dyspepsia and constipation, which aims to provide essential information to guide therapeutic decisions during this crucial period of motherhood. Objectives: To analyze the information in package inserts about contraindications of drugs for dyspepsia and constipation during breastfeeding, verifying whether these are consistent with scientific evidence. Methods: Drugs for dyspepsia and constipation were selected according to the Anatomical Therapeutic Chemical (ATC) classification and active registry in Brazil. The presence of contraindications for the use of medications in the health professional's and patient's package inserts was compared with the information in the technical manual of the Ministry of Health, Medications and Mothers' Milk, LactMed, UptoDate, Micromedex, Documento Científico da Sociedade Brasileira de Pediatria and Reprotox. Results: No information about use during breastfeeding was found in 20.0 and 24.3% of leaflets for dyspepsia and constipation, respectively. The agreement between the leaflets of medications for dyspepsia and the sources consulted was low (27.2% of the leaflets contraindicated the medication during lactation, while in the sources the percentage of contraindication varied from 0 to 8.3%). In relation to medicines for constipation, 26.3% of the leaflets contraindicated them, while in the sources the percentage ranged from 0 to 4.8%. Conclusions: The study pointed out that at least two out of every ten package inserts for dyspepsia and constipation do not provide adequate information on the use of these drugs in infants, and also shows low concordance between the text of the package inserts and the reference sources regarding compatibility of the drug with breastfeeding.

RESUMEN

BACKGROUND: The gastrointestinal symptom rating scale (GSRS) is a questionnaire in English language which is designed to assess the clinical symptoms in patients with irritable bowel syndrome (IBS) and peptic ulcer disease. This validated scale has questions on around 15 items and has been validated in patients with dyspepsia and IBS. AIM: To translate and validate the English version of the GSRS questionnaire to the Hindi version. METHODS: The purpose of the present work was to create a Hindi version of this questionnaire for use in the Indian population. The process involved various steps as per the World Health Organization methodology including initial forward translation, backward translation, and assessment by an expert committee. Initial pilot testing was followed by testing in healthy and diseased individuals. RESULTS: The Hindi translation was pilot tested in 20 individuals and further validated in healthy controls (n = 30, 15 females) and diseased individuals (n = 72, 27 females). The diseased group included patients with functional dyspepsia and IBS. Cronbach's alpha for internal consistency on the final translated GSRS questionnaire was 0.715 which is considered adequate. Twelve questions significantly differentiated the diseased population from the healthy population (P value < 0.05) in the translated Hindi version of the GSRS. CONCLUSION: The translated Hindi GSRS can be used to evaluate gastrointestinal function in clinical trials and community surveys in Hindi speaking populations.

RESUMEN

BACKGROUND: Functional constipation (FC) is a common gastrointestinal disorder characterized by abdominal pain and bloating, which can greatly affect the quality of life of patients. Conventional treatments often yield suboptimal results, leading to the exploration of alternative therapeutic approaches. AIM: To evaluate the efficacy of KiwiBiotic in the management of FC and related symptoms. METHODS: This prospective, interventional, single-center, crossover study compared the safety and effectiveness of KiwiBiotic® vs psyllium husk in managing FC, abdominal pain, and bloating. Participants diagnosed with FC were randomly assigned to receive KiwiBiotic or psyllium husk during the two treatment periods, with a 14-day washout period between them. RESULTS: Seventy participants were enrolled, 32 of whom received KiwiBiotic followed by psyllium husk, and 33 received KiwiBiotic. KiwiBiotic showed superiority over psyllium husk in alleviating abdominal pain and bloating, as evidenced by significantly lower mean scores. Furthermore, KiwiBiotic resulted in more than 90.0% of patients experiencing relief from various constipation symptoms, while psyllium husk showed comparatively lower efficacy. CONCLUSION: KiwiBiotic is an effective treatment option for FC, abdominal pain, and bloating, highlighting its potential as a promising alternative therapy for patients with FC and its associated symptoms.

RESUMEN

Objectives. Constipation is one of the most common gastrointestinal symptoms in children with neurological disorders. This study was performed to compare the therapeutic effect of polyethylene glycol (PEG) plus domperidone with PEG plus placebo in the treatment of chronic constipation in children with cerebral palsy. Methods. In this a double-blind clinical trial study was done on the children with cerebral palsy who had chronic constipation and was referred to Mohammad Kermanshahi hospital of Kermanshah city in the west of Iran. The participants were randomly divided into 2 groups with 2 therapies of PEG combined with domperidone (case group, n = 21) and PEG with placebo (control group, n = 21). The information was extracted from patients based on the checklist before and after treatment and the response to treatment in the 2 groups were determined and compared. The data were analyzed by T-test or Mann-Whitney U test to compare quantitative variables and Chi-square and Fisher's exact tests for comparing qualitative variables. Results. In both case and control groups, all Rome IV criteria for a diagnosis of chronic constipation except incontinence were significantly reduced after treatment. However, the successful response rate in the case group (PEG + domperidone) was 90.5%, while this rate was 61.9% in the control group. Conclusion. Based on the results of the present study, it seems that PEG plus domperidone had a positive effect on the treatment of children with cerebral palsy and chronic constipation.

RESUMEN

Introduction: This study evaluated constipation, including reduced bowel movement frequency and difficult defecation, in patients with isolated rapid eye movement sleep behavior disorder (IRBD), which is prodromal Parkinson's disease (PD) or dementia with Lewy bodies (DLB) in middle-aged and older adults. Methods: We used a validated Japanese version of the Constipation Assessment Scale (CAS-J) to evaluate bowel habits over 1 month in 117 men aged 50-86 years and 34 women aged 56-86 years with video-polysomnography-confirmed IRBD and 22 controls. Furthermore, we performed a longitudinal assessment of outcomes at follow-up visits. Results: The CAS-J score was higher in the 22 IRBD patients than in 22 age- and gender-matched paired controls. In 151 IRBD patients, the CAS-J score was higher for women than for men. At baseline, the CAS-J score was similar between patients who developed PD and DLB, but the three IRBD patients who developed multiple system atrophy had a low CAS-J score. Those with constipation (CAS-J score ≥ 2) converted to PD or DLB in a significantly shorter time duration (i.e., time frame for phenoconversion) than those with CAS-J score < 2 (log-rank test, p < 0.001). When adjusted for age and gender, Cox hazards analysis revealed that the CAS-J score significantly predicted phenoconversion to PD or DLB (hazard ratio: 5.9, 95 % confidence interval: 1.8-19.1, p = 0.003). Conclusions: Constipation, i.e., reduced bowel movement frequency and difficult defecation, was common in middle-aged and elderly patients with IRBD, and CAS-J score predicted phenoconversion to PD or DLB.

RESUMEN

Objective: This project aims to identify the top 30 drugs most commonly associated with constipation and their signal values within the FDA Adverse Event Reporting System database. Methods: We extracted adverse drug events (ADEs) related to constipation from the FAERS database spanning from January 1, 2004, to September 30, 2023. We compiled the 30 most frequently reported drugs based on the frequency of constipation events. We employed signal detection methodologies to ascertain whether these drugs elicited significant signals, including reporting odds ratio, proportional reporting ratio, multi-item gamma Poisson shrinker, and information component given by the Bayesian confidence propagation neural network. Furthermore, we conducted a time-to-onset (TTO) analysis for drugs generating significant signals using the medians, quartiles, and the Weibull shape parameter test. Results: We extracted a total of 50, 659, 288 ADEs, among which 169,897 (0.34%) were related to constipation. We selected and ranked the top 30 drugs. The drug with the highest ranking was lenalidomide (7,730 cases, 4.55%), with the most prevalent drug class being antineoplastic and immunomodulating agents. Signal detection was performed for the 30 drugs, with constipation risk signals identified for 26 of them. Among the 26 drugs, 22 exhibited constipation signals consistent with those listed on the FDA-approved drug labels. However, four drugs (orlistat, nintedanib, palbociclib, and dimethyl fumarate) presented an unexpected risk of constipation. Ranked by signal values, sevelamer carbonate emerged as the drug with the strongest risk signal [reporting odds ratio (95% CI): 115.51 (110.14, 121.15); PRR (χ2): 83.78 (191,709.73); EBGM (EB05): 82.63 (79.4); IC (IC025): 6.37 (4.70)]. A TTO analysis was conducted for the 26 drugs that generated risk signals, revealing that all drugs exhibited an early failure type. The median TTO for orlistat was 3 days, the shortest of all the drugs, while the median TTO for clozapine was 1,065 days, the longest of all the drugs. Conclusion: Our study provides a list of drugs potentially associated with drug-induced constipation (DIC). This could potentially inform clinicians about some alternative medications to consider when managing secondary causes of constipation or caring for patients prone to DIC, thereby reducing the incidence and mortality associated with DIC.

RESUMEN

Background: Many patients with constipation also suffer from varying degrees of malnutrition, and the relationship between the two conditions is a vicious cycle. Surgery is the final step in the treatment of constipation, with a success rate of up to 95%. This study aims to investigate the effects of surgical treatment on the nutritional status of patients with chronic constipation and malnutrition. Methods: A total of 60 patients with chronic constipation and various degrees of malnutrition who underwent surgery in our department from January 2020 to March 2023 were included in this study. Biochemical tests including BMI, albumin, total protein, hemoglobin, cholesterol and lymphocyte count were conducted, as well as measurements of inflammatory markers such as Interleukin-6 (IL-6), Interleukin-8 (IL-8), and C-reactive protein (CRP). Additionally, multiple nutritional risk screening scales (NRS2002, MUST, NRI, and MNA) and the prognostic nutritional index (PNI) were used to assess the nutritional status of patients before surgery, as well as at 1 month, 3 months, and 6 months post-surgery. Finally, we analyzed the factors influencing postoperative recovery outcomes in patients. Results: Compared to pre-operation, the BMI of patients significantly increased at 1 month, 3 months, and 6 months after the operation, with statistically significant differences (p < 0.001). Multiple nutritional risk assessment tools (NRS2002, MUST, NRI, and MNA), as well as the prognostic nutritional index (NPI), indicated a reduction in nutritional risk and improvement in nutritional status at 1, 3, and 6 months post-surgery, compared to pre-surgery levels (p < 0.001). The levels of albumin, total protein, and hemoglobin in patients at 1, 3, and 6 months after the surgery were significantly higher than those before the surgery (p < 0.001). However, there was no significant change in the number of lymphocytes. Inflammatory markers such as IL-6, IL-8, and CRP exhibited a significant decrease after the surgery, reaching normal levels at 6 months post-surgery (p < 0.001). Low BMI, low PNI, and low cholesterol levels are independent risk factors for patient prognosis (p < 0.05). Conclusion: Surgical treatment can enhance the nutritional status of constipation patients with malnutrition, which in turn promotes the restoration of intestinal motility. The patient's nutritional status will impact the postoperative recovery outcomes.

RESUMEN

Gastro-intestinal ultrasound (GIUS) is a non-invasive and cost-effective tool, widely used as a first-line diagnostic method in patients presenting with abdominal complaints, especially in patients affected by inflammatory bowel disease (IBD), such as Crohn's disease and ulcerative colitis. In this setting, gastro-intestinal ultrasound has been especially used to evaluate the bowel wall features (thickening, stratification, vascularization) and complications related to IBD (fistulas, abscesses). Nevertheless, gastro-intestinal ultrasound can be also used to detect and evaluate the content of several segments of the gut. In fact, there is a growing interest in utilizing GIUS for suspected functional disorders, where assessing intestinal content may play a significant diagnostic role, as well as directing therapy. In our review, we provided a sonographic description of GIUS appearances of bowel content in various pathological and physiological conditions, offering potential applications in clinical practice and providing insights for further research.

RESUMEN

Complement component 3 (C3) deficiency has recently been reported as one of the novel causes of constipation. To identify a unique gene specific to constipation caused by C3 deficiency, the total RNA extracted from the mid colon of C3 knockout (C3 KO) mice was hybridized to oligonucleotide microarrays, and the function of the candidate gene was verified in in vitro and in vivo models. C3 KO mice used for microarrays showed definite phenotypes of constipation. Overall, compared to the wild type (WT), 1237 genes were upregulated, and 1292 genes were downregulated in the C3 KO mice. Of these, the major genes included were lysine (K)-specific demethylase 5D (KDM5D), olfactory receptor 870 (Olfr870), pancreatic lipase (PNLIP), and alkaline phosphatase intestinal (ALPI). Specifically, the ALPI gene was selected as a novel gene candidate based on alterations during loperamide (Lop)-induced constipation and intestinal bowel disease (IBD). The upregulation of ALPI expression treated with acetate recovered the expression level of mucin-related genes in primary epithelial cells of C3 KO mice as well as most phenotypes of constipation in C3 KO mice. These results indicate that ALPI plays an important role as the novel gene associated with C3 deficiency-induced constipation.

RESUMEN

Parkinson's disease is associated with gastrointestinal (GI) dysfunction, including constipation symptoms and abnormal intestinal permeability and inflammation. A Mediterranean diet (MediDiet) may aid in disease management. This parallel, randomized, controlled trial in people with Parkinson's (PwP) and constipation symptoms compared a MediDiet against standard of care on change in constipation symptoms, dietary intake, and fecal zonulin and calprotectin concentrations as markers of intestinal permeability and inflammation, respectively. Participants were randomized to either standard of care for constipation (control; n = 17, 65.1 ± 2.2 years) or a MediDiet plus standard of care (n = 19, 68.8 ± 1.4 years) for 8 weeks. Constipation scores decreased with both interventions (p < 0.01), but changes from baseline were not different between groups (MediDiet, -0.5 [-1.0, 0]; control, -0.8 [-1.0, 0.2]; median [25th, 75th]; p = 0.60). The MediDiet group had a higher intake of dietary fiber at week 4 than the control group (13.1 ± 0.7 g/1000 kcal vs. 9.8 ± 0.7 g/1000 kcal; p < 0.001). No differences in fecal zonulin were observed between groups (p = 0.33); however, fecal calprotectin tended to be lower in the MediDiet group at week 8 (45.8 ± 15.1 µg/g vs. 93.9 ± 26.8 µg/g; p = 0.05). The MediDiet and standard interventions reduced constipation symptoms; however, the MediDiet provided additional benefit of increased dietary fiber intake and less intestinal inflammation.

RESUMEN

BACKGROUND: The causes of functional constipation (FC) in adults are unclear, but changes in the gut microbiome may play an important role. The present study aimed to assess the relationship between urinary metabolites of dopamine and serotonin and some dysbiosis indicators in patients with FC. The study included 40 healthy women and 40 women with FC aged 21-46 years. METHODS: Urinary levels of homovanillic acid (HVA), 5-hydoxyindoleacetic acid (5-HIAA), p-hydroxyphenylacetic acid (PhAc), and 3-indoxyl sulfate, as final metabolites of dopamine, serotonin, and indole pathway, respectively, were determined using the LC-Ms/Ms method. However, hydrogen-methane and ammonia breath tests were performed. The GA-map Dysbiosis Test was used to identify and characterize the dysbiosis index (DI). RESULTS: In patients with FC, the DI was significantly higher than in the control group: 4.05 ± 0.53 vs. 1.52 ± 0.81 points (p < 0.001), but the number of many types of bacteria varied among individuals. The levels of HVA were higher, while 5-HIAA levels were lower in patients. Moreover, the HVA/5-HIAA ratio had a positive correlation with DI as well as with the severity of symptoms. CONCLUSIONS: In patients with functional constipation, the balance in dopamine and serotonin secretion is disturbed, which is associated with changes in the gut microbiome.

RESUMEN

Constipation, a widespread gastrointestinal disorder, often leads to the exploration of natural remedies. This study examines the efficacy of Golden Flower Tibetan Tea Polysaccharides (GFTTPs) in alleviating constipation in mice. Chemical analyses reveal that GFTTPs possess O-H, carboxyl, carboxylic acid (-COOH), and C-O-C groups, alongside a porous crystal structure with thermal stability. In animal experiments, GFTTPs significantly upregulated aquaporin 3 (AQP3) and aquaporin 8 (AQP8) expressions in the colon, enhancing water absorption and reducing fecal water content. At a 400 mg/kg dosage, GFTTPs notably improved colonic tissue alterations and serum levels of excitatory neurotransmitters caused by loperamide hydrochloride. They also beneficially altered gut microbiota, increasing Coprococcus, Lactobacillus, and Pediococcus populations. These changes correlated with improved stool frequency, consistency, and weight in constipated mice. Importantly, GFTTPs at 200 and 400 mg/kg doses exhibited comparable effects to the normal control group in key parameters, such as gastrointestinal transit rate and fecal moisture. These findings suggest that GFTTPs may serve as a potent natural remedy for constipation, offering significant therapeutic potential within the context of gut health and with promising implications for human applications.

RESUMEN

Background: It is well known that opiates slow gastrointestinal (GI) transit, via suppression of enteric cholinergic neurotransmission throughout the GI tract, particularly the large intestine where constipation is commonly induced. It is not clear whether there is uniform suppression of enteric neurotransmission and colonic motility across the full length of the colon. Here, we investigated whether regional changes in colonic motility occur using the peripherally-restricted mu opioid agonist, loperamide to inhibit colonic motor complexes (CMCs) in isolated mouse colon. Methods: High-resolution video imaging was performed to monitor colonic wall diameter on isolated whole mouse colon. Regional changes in the effects of loperamide on the pattern generator underlying cyclical CMCs and their propagation across the full length of large intestine were determined. Results: The sensitivity of CMCs to loperamide across the length of colon varied significantly. Although there was a dose-dependent inhibition of CMCs with increasing concentrations of loperamide (10 nM - 1 µM), a major observation was that in the mid and distal colon, CMCs were abolished at low doses of loperamide (100 nM), while in the proximal colon, CMCs persisted at the same low concentration, albeit at a significantly slower frequency. Propagation velocity of CMCs was significantly reduced by 46%. The inhibitory effects of loperamide on CMCs were reversed by naloxone (1 µM). Naloxone alone did not change ongoing CMC characteristics. Discussion: The results show pronounced differences in the inhibitory action of loperamide across the length of large intestine. The most potent effect of loperamide to retard colonic transit occurred between the proximal colon and mid/distal regions of colon. One of the possibilities as to why this occurs is because the greatest density of mu opioid receptors are located on interneurons responsible for neuro-neuronal transmission underlying CMCs propagation between the proximal and mid/distal colon. The absence of effect of naloxone alone on CMC characteristics suggest that the mu opioid receptor has little ongoing constitutive activity under our recording conditions.

RESUMEN

Aim: To determine the frequency and possible associated dietary and environmental factors of functional constipation (FC) among children in Lebanon followed at a single pediatric health system. Method: A prospective cross-sectional study was conducted in all pediatrics clinics at the American University of Beirut Medical Center (AUBMC). Children aged 2-7 years presenting for a well-child visit were recruited. Data relating to the child's bowel habits and other history items were obtained from parental questionnaires. Results: The mean age of the 172 recruited participants was 4.94 years with 56.4% being males. FC was present in 32.6% of the participants. Although there was no difference in the frequency of FC based on age and gender, the peak frequency of FC was at 5 years. The daily frequency of withholding stools was 64.3%, and 46.6% of the children with FC always experienced straining while stooling for the past 2 months. Decreased physical activity and diet were not significantly associated with FC. Conclusion: The present study shows that 32.6% of children aged 2-7 years in Lebanon suffer from constipation while only 51.7% of the recruited children's physicians inquire about the child's bowel movement during the well check visit. These numbers highlight the need to raise more awareness among pediatricians on the need to screen for constipation during clinic visits as a standard of care practice.

RESUMEN

BACKGROUND: Supplementation with the Agave tequilana Weber blue variety fructans is a feasible treatment option for functional constipation (FC). However, its effects on colonic function have not yet been studied. This study assessed whole gut transit time (WGTT) and regional transit time using a wireless motility capsule (WMC) before and after supplementation with different fiber treatments in patients with FC. METHODS: A secondary analysis was performed on data collected from a randomized, double-blind clinical trial comparing agave fructans with psyllium plantago. WGTT, regional transit time, contractility, and pH were measured using WMC before and after fiber supplementation. Comparisons were performed using nonparametric tests. KEY RESULTS: Twenty patients with FC were evaluated, with a median age of 39 (25-54 years), and 18 (90%) were women. Five patients were included in each intervention group. There were no changes in WGTT or regional transit times between the groups (p > 0.05). Similarly, there were no differences in the changes experienced by regional or general contractility among the groups (p > 0.05). The cecal pH profile did not differ between the groups before and after fiber supplementation (p > 0.05). The percentages of clinical responses and consistency of bowel movements between the groups were similar. CONCLUSIONS & INFERENCES: FC presents a clinical response to a fiber challenge, regardless of the administered intervention. However, this response was not associated with improvement in contractility or regional transit time. We speculate that there are other mechanisms by which fiber consumption may improve FC.

RESUMEN

BACKGROUND: Irritable bowel syndrome (IBS) is a disorder of gut-brain interaction characterized by abdominal pain and altered bowel habits, with patient-perceived dissatisfaction of treatment symptom control. We assessed disease burden, satisfaction with medication use, and impact on activities, in participants with IBS with constipation (IBS-C) and diarrhea (IBS-D). METHODS: This study assessed data from a large, United States survey of adults querying demographics, comorbid conditions, quality of life, medication use, satisfaction with symptom control, and work productivity. Participants were grouped into the IBS-C or IBS-D cohort if they met Rome IV criteria, with controls matched 1:1 according to age, sex, race, region, and Charlson Comorbidity Index score. All data were self-reported. KEY RESULTS: Nine hundred and ten participants with IBS-C and 669 with IBS-D were matched to controls. The most reported symptoms were abdominal discomfort for IBS-C and abdominal pain and abdominal discomfort for IBS-D. Among the IBS-C and IBS-D cohorts, 74.2% and 65.9%, respectively, took prescription and/or over-the-counter medication for their symptoms. Respondents were more dissatisfied than satisfied with control of their symptoms. Respondents taking prescription medication(s) with or without over-the-counter medication(s) reported better symptom control than respondents only taking over-the-counter medications (p < 0.001). There was significantly higher mean presenteeism, work productivity loss, and daily activity impairment (p < 0.001 for all) in respondents with IBS compared with controls. CONCLUSIONS AND INFERENCES: This study provides insight into respondents' experiences of IBS symptoms, including the impact on daily activity, as well as satisfaction with control of symptoms and prescription and over-the-counter medications.

RESUMEN

Functional constipation (FC) comprises 30% of pediatric gastroenterology clinic visits. FC results from withholding behaviors that can be worsened by poor toileting posture. The use of a defecation posture modification device (DPMD)-a potty stool-has demonstrated benefit in adults. The aim of this study was to assess the risks and benefits of incorporating a DPMD as an adjunct to the FC treatment plan for children. Toilet-trained children aged ≥4 years meeting the Rome IV criteria for FC were enrolled and offered a DPMD at no cost and were followed for 4 months. There were no injuries or treatment-related adverse events reported by the 43 subjects who completed the study. Notably, 98% (n = 42) of respondents would recommend the DPMD to assist other children with FC. DPMD users showed a 33% reduction in fecal incontinence compared with 60% non-users. The DPMD represents a safe adjunct to incorporate into the FC management plan of children.

RESUMEN

BACKGROUND: Constipation is prevalent after bariatric surgery and glucagon-like-peptide 1 (GLP-1) analogues. Increasing fat content in the distal small intestine and colon can enhance colonic peristalsis, potentially alleviating symptoms of constipation. AIM: We investigated whether oleic acid can ameliorate constipation in patients undergoing bariatric surgery or receiving GLP-1 analogues. METHODOLOGY: Fourteen adults with chronic constipation according to Rome IV criteria following bariatric surgery or GLP-1 analogues were on stable treatment for constipation for more than 4 weeks. This randomized double-blind crossover trial compared microcapsules containing 21.25 g of oleic acid delivered in the distal small intestine or the stomach. The primary outcome was changed in the number of bowel motions over 24 h. Exploratory endpoints included alterations in straining, diarrhoea, faecal leakage over 24 h and hunger, fullness, nausea and calorie intake for the 3 h after ingesting the microcapsules. FINDINGS: Receiving oleic acid into the distal small intestine increased number of bowel movements per day (2.5 vs 1.1, p = 0.009) and caused softer stool consistency (p = 0.03). 9/14 of the control group passed motions and 13/14 of the intervention group passed motions in 24 h (p = 0.059). No significant differences were observed in straining (p = 0.65), rapid bowel movements (p = 0.08), accidental leakage (p = 0.32), hunger, fullness, nausea or food intake between the groups (all p > 0.05). There were no disparities in safety profile between groups. CONCLUSION: Microcapsules containing oleic acid delivered to the distal small intestine appear to be a safe and effective relief from chronic constipation in patients undergoing bariatric surgery and/or receiving GLP-1 analogues.

RESUMEN

Chronic constipation is a prevalent clinical condition. Its etiology and pathogenesis have not yet been fully understood. In recent years, mounting evidence suggests a close association between chronic constipation and intestinal dysbiosis, including alterations in the colony structure and metabolites, as well as the modulation of bowel movements via the brain-gut-microbiota axis. With the deepening of related research, probiotic-related therapies are expected to become a potential first-line treatment for chronic constipation in the future. In this review, we summarize the current research insights into the intricate relationships between chronic constipation and the gut microbiota and briefly discuss several different approaches for treating chronic constipation. The findings from this review may advance our understanding of the pathological mechanisms underlying chronic constipation and, ultimately, translate them into improvements in patient care.
