El consumo de dos kiwis diarios podría mejorar el hábito intestinal en personas con estreñimiento crónico / Daily consumption of two kiwifruits could improve bowel habits in people with chronic constipation

A partir del caso de una paciente con síndrome de intestino irritable a predominio de estreñimiento cuyos síntomas mejoraron con el consumo regular de kiwi, el médico de familia se planteó la pregunta de si el kiwi podría mejorar los síntomas asociados a constipación crónica en comparación con el tratamiento habitual. Tras realizar una búsqueda de estudios que analizaran los efectos del consumo de kiwi sobre el hábito intestinal, fueron seleccionados tres artículos que permiten concluir que el consumo de esta fruta tiene una eficacia superior al placebo y comparable al psyllium y las pasas de ciruela para mejorar los síntomas de personas con estreñimiento crónico.

Dietary Supplement Use in Gastrointestinal Symptom Management and Effect on Hopelessness Levels in Patients With Irritable Bowel Syndrome.

This study was conducted to determine the dietary supplement (DS) use in gastrointestinal symptom management, and its effect on hopelessness levels in patients with irritable bowel syndrome (IBS). The universe of this cross-sectional study consisted of 132 patients presenting at the polyclinic, while the sample consisted of 127 patients who meet the inclusion criteria to study. Data were collected using a patient identification form including sociodemographic characteristics and DS use, the Gastrointestinal Symptom Rating Scale, and the Beck Hopelessness Scale. The frequency of DS use in the last year among patients with IBS was 73.2%. Younger, women, those with graduate education, and those with better economic status were found to prefer more DS (P < .0001). Nausea and decreased passage of stools were predictors of DS use with a rate of 40.9% (R = 0.409, P < .0001). The patients were found to use mint oil (35.6%), mint juice (24.6%), lemon (20.5%) for nausea, and apricots (48.2%) and dietary fibers (16.9%) for decreased passage of stools. Patients who did not use DSs were found to be more hopeless (P < .03). It was found that 73.2% of patients with IBS used DSs. Patients who did not use DSs were found to be more hopeless. DSs with proven effectiveness can be integrated into medical treatments.

Gastrointestinal symptom improvement from fiber, STW 5, peppermint oil, and probiotics use-Results from an online survey.

OBJECTIVES: Several common supplements are used by a significant number of patients affected by gastrointestinal (GI) disorders to improve symptoms and quality of life. We investigated the impact of GI symptom improvement with the use of fiber, STW 5, probiotics, and peppermint oil in relation to overall GI pain and quality of life via an online survey. DESIGN: We used a cross-sectional, descriptive, correlation design. A Qualtrics online survey was utilized to collect data from January to June 2013 through various websites. Areas evaluated included participant demographics, use of supplements, and gastrointestinal symptom severity. RESULTS: The rate of supplement use among patients with GI disorders was high (90% in past year) and consultation with healthcare providers was reported by 80%. Participants who completed the survey (n = 68) reported a strong correlation between GI symptom severity and overall quality of life (r2 = 0.8682, p < 0.001). The use of fiber improved GI symptom severity while both STW 5 and probiotics were linked to specific improvements. CONCLUSIONS: Persons with chronic GI disorders often choose the complementary use of common supplements to mitigate GI symptoms and consult with their healthcare providers frequently. The use of STW 5 and probiotics specifically is linked to overall reduction in GI symptoms and improvement of quality of life.

Probiotics in cystic fibrosis patients: A double blind crossover placebo controlled study: Pilot study from the ESPGHAN Working Group on Pancreas/CF.

BACKGROUND: A potential positive effect of probiotics in cystic fibrosis (CF) on fecal calprotectin (FCP), pulmonary exacerbations and weight has been described in small controlled trials. METHODS: A double-blind multicenter cross-over study (2 × 4 m) was performed looking at abdominal pain, nutritional status, pulmonary function, pulmonary exacerbation, FCP and lactulose/mannitol gut permeability test. Patients kept a diary with daily scoring of abdominal pain, stool frequency and consistency as well as treatment changes. RESULTS: 31 CF patients entered the study of which 25 finished it. At start patients aged 9.3yrs (6.9-12.2), had a median BMI z-score of -0.5 (-1.5-0.08), height z-score of -0.4 (-1.1-0.05) and FEV1% of 100% (87.2-106.6). Median FCP at start was 61 µg/g (17-108) and gut permeability 0.079 (0.051-0.122). No significant changes were observed in the clinical parameters (BMI, FEV1%, abdominal pain, exacerbations). Despite being frequently abnormal (17/28 (61%) >50 mg/kg), FCP did not change significantly with probiotics. The proportion of patients with normal permeability was 8% during placebo and 32% during probiotic treatment (p = 0.031). FCP correlated to BMI z-score (p = 0.043) and gut permeability to abdominal pain (p = 0.015). The microbiome revealed a high predominance of Actinobacteria and Proteobacteriae. Probiotic supplementation did not result in a shift at the phylum nor at phylogenetic level. CONCLUSION: Normalization of gut permeability was observed in 13% of patients during probiotic treatment. However, none of the previously described effects could be confirmed.

Guía de práctica clínica del síndrome del intestino irritable con estreñimiento y estreñimiento funcional en adultos: tratamiento. (Parte 2 de 2) / Irritable bowel syndrome with constipation and functional constipation in adults: treatment (Part 2 of 2)

En esta Guía de práctica clínica analizamos el manejo diagnóstico y terapéutico de pacientes adultos con estreñimiento y molestias abdominales, bajo la confluencia del espectro del síndrome del intestino irritable y el estreñimiento funcional. Ambas patologías están encuadradas en los trastornos funcionales intestinales y tienen una importante repercusión personal, sanitaria y social, afectando a la calidad de vida de los pacientes que las padecen. La primera es el subtipo de síndrome del intestino irritable en el que el estreñimiento es la alteración deposicional predominante junto con dolor abdominal recurrente, hinchazón y distensión abdominal frecuente. El estreñimiento se caracteriza por la dificultad o la escasa frecuencia en relación con las deposiciones, a menudo acompañado por esfuerzo excesivo durante la defecación o sensación de evacuación incompleta. En la mayoría de los casos no tiene una causa orgánica subyacente, siendo considerado un trastorno funcional intestinal. Son muchas las similitudes clínicas y fisiopatológicas entre ambos trastornos, con respuesta similar del estreñimiento a fármacos comunes, siendo la diferencia fundamental la presencia o ausencia de dolor, pero no de un modo evaluable como «todo o nada». La gravedad de estos trastornos depende no solo de la intensidad de los síntomas intestinales sino también de otros factores biopsicosociales: asociación de síntomas gastrointestinales y extraintestinales, grado de afectación, y formas de percepción y comportamiento. Mediante los criterios de Roma, se diagnostican los trastornos funcionales intestinales. Esta Guía de práctica clínica está adaptada a los criterios de Roma IV difundidos a finales de mayo de 2016. En una primera parte (96, 97, 98) se analizaron los aspectos conceptuales y fisiopatológicos, los criterios de alarma, las pruebas diagnósticas y los criterios de derivación entre Atención Primaria y aparato digestivo. En esta segunda parte, se revisan todas las alternativas terapéuticas disponibles (ejercicio, ingesta de líquidos, dieta con alimentos ricos en fibra soluble, suplementos de fibra, otros componentes de la dieta, laxantes osmóticos o estimulantes, probióticos, antibióticos, espasmolíticos, esencia de menta, prucaloprida, linaclotida, lubiprostona, biofeedback, antidepresivos, tratamiento psicológico, acupuntura, enemas, neuroestimulación de raíces sacras o cirugía), efectuando recomendaciones prácticas para cada una de ellas (AU)

In this Clinical practice guide we examine the diagnostic and therapeutic management of adult patients with constipation and abdominal discomfort, at the confluence of the spectrum of irritable bowel syndrome and functional constipation. Both fall within the framework of functional intestinal disorders and have major personal, health and social impact, altering the quality of life of the patients affected. The former is a subtype of irritable bowel syndrome in which constipation and altered bowel habit predominate, often along with recurring abdominal pain, bloating and abdominal distension. Constipation is characterised by infrequent or hard-to-pass bowel movements, often accompanied by straining during defecation or the sensation of incomplete evacuation. There is no underlying organic cause in the majority of cases; it being considered a functional bowel disorder. There are many clinical and pathophysiological similarities between the two conditions, the constipation responds in a similar way to commonly used drugs, the fundamental difference being the presence or absence of pain, but not in an «all or nothing» way. The severity of these disorders depends not only on the intensity of the intestinal symptoms but also on other biopsychosocial factors: association of gastrointestinal and extraintestinal symptoms, degree of involvement, forms of perception and behaviour. Functional bowel disorders are diagnosed using the Rome criteria. This Clinical practice guide adapts to the Rome IV criteria published at the end of May 2016. The first part (96, 97, 98) examined the conceptual and pathophysiological aspects, alarm criteria, diagnostic test and referral criteria between Primary Care and Gastroenterology. This second part reviews all the available treatment alternatives (exercise, fluid ingestion, diet with soluble fibre-rich foods, fibre supplements, other dietary components, osmotic or stimulating laxatives, probiotics, antibiotics, spasmolytics, peppermint essence, prucalopride, linaclotide, lubiprostone, biofeedback, antdepressants, psychological treatment, acupuncture, enemas, sacral root neurostimulation and surgery), and practical recommendations are made for each (AU)

Randomised clinical trial: the analgesic properties of dietary supplementation with palmitoylethanolamide and polydatin in irritable bowel syndrome.

BACKGROUND: Intestinal immune activation is involved in irritable bowel syndrome (IBS) pathophysiology. While most dietary approaches in IBS involve food avoidance, there are fewer indications on food supplementation. Palmithoylethanolamide, structurally related to the endocannabinoid anandamide, and polydatin are dietary compounds which act synergistically to reduce mast cell activation. AIM: To assess the effect on mast cell count and the efficacy of palmithoylethanolamide/polydatin in patients with IBS. METHODS: We conducted a pilot, 12-week, randomised, double-blind, placebo-controlled, multicentre study assessing the effect of palmithoylethanolamide/polydatin 200 mg/20 mg or placebo b.d. on low-grade immune activation, endocannabinoid system and symptoms in IBS patients. Biopsy samples, obtained at screening visit and at the end of the study, were analysed by immunohistochemistry, enzyme-linked immunoassay, liquid chromatography and Western blot. RESULTS: A total of 54 patients with IBS and 12 healthy controls were enrolled from five European centres. Compared with controls, IBS patients showed higher mucosal mast cell counts (3.2 ± 1.3 vs. 5.3 ± 2.7%, P = 0.013), reduced fatty acid amide oleoylethanolamide (12.7 ± 9.8 vs. 45.8 ± 55.6 pmol/mg, P = 0.002) and increased expression of cannabinoid receptor 2 (0.7 ± 0.1 vs. 1.0 ± 0.8, P = 0.012). The treatment did not significantly modify IBS biological profile, including mast cell count. Compared with placebo, palmithoylethanolamide/polydatin markedly improved abdominal pain severity (P < 0.05). CONCLUSIONS: The marked effect of the dietary supplement palmithoylethanolamide/polydatin on abdominal pain in patients with IBS suggests that this is a promising natural approach for pain management in this condition. Further studies are now required to elucidate the mechanism of action of palmithoylethanolamide/polydatin in IBS. ClinicalTrials.gov number, NCT01370720.

Dietary and pharmacological treatment of abdominal pain in IBS.

This review introduces the principles of visceral sensation and appraises the current approaches to management of visceral pain in functional GI diseases, principally IBS. These approaches include dietary measures including fibre supplementation, low fermentable oligosaccharides, disaccharides, monosaccharides and polyols diet, and pharmacological approaches such as antispasmodics, peppermint oil, antidepressants (tricyclic agents, selective serotonin reuptake inhibitors), 5-HT3 receptor antagonists (alosetron, ondansetron, ramosetron), non-absorbed antibiotic (rifaximin), secretagogues (lubiprostone, linaclotide), µ-opioid receptor (OR) and κ-OR agonist, δ-OR antagonist (eluxadoline), histamine H1 receptor antagonist (ebastine), neurokinin-2 receptor antagonist (ibodutant) and GABAergic agents (gabapentin and pregabalin). Efficacy and safety are discussed based on pivotal trials or published systematic reviews and meta-analysis, expressing ORs or relative risks and their 95% CIs. Potential new approaches may be based on recent insights on mucosal expression of genes, and microRNA and epigenetic markers in human biopsies and in animal models of visceral hypersensitivity.The objectives of this review are to appraise the physiology and anatomy of gut sensation and the efficacy in the relief of visceral pain (typically in IBS) of several classes of therapies. These include fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs) and different classes of medications (box 1).

Symbiotics in irritable bowel syndrome--better than probiotics alone?

PURPOSE OF REVIEW: Irritable bowel syndrome (IBS) is a chronic gastrointestinal disorder associated with significant physical and psychological comorbidity. The etiology of the condition is uncertain but recent research suggests that the gut bacterial composition may play a role in its development. Therefore, manipulation of the intestinal microbiome by using probiotics and symbiotics has the potential to improve patient outcomes in IBS. RECENT FINDINGS: Numerous randomized controlled trials suggest a benefit of probiotics in the management of IBS, with a significant reduction in the likelihood of symptoms persisting after therapy, and improvements in abdominal pain, bloating and flatulence when probiotics are compared with placebo. Evidence for the effect of probiotics on quality of life is conflicting. Relatively few randomized controlled trials have examined the effect of symbiotics on outcomes in IBS, but results thus far are promising. SUMMARY: Probiotics appear to be beneficial in IBS. Data supporting the use of symbiotics is sparse. Whether symbiotics are superior to probiotics is unclear.

Factors associated with intolerance after refeeding in mild acute pancreatitis.

OBJECTIVES: This study aimed to describe the mode of refeeding, frequency of intolerance, and related factors in mild acute pancreatitis (AP). METHODS: We included all cases of mild AP between January 2007 and December 2009 in an observational, descriptive, and retrospective study. We analyzed demographic and etiological data, admission variables, treatment, refeeding mode, intolerance frequency, and treatment. Intolerance-related variables were determined using a Cox regression. RESULTS: Two-hundred thirty-two patients were included (median age, 74.3 years, bedside index for severity in AP score, 1). Oral diet was reintroduced at 3 days (range, 0-11 days) in 90.9% of cases with a liquid diet. Intolerance to refeeding appeared in 28 patients (12.1%) at a median time of 1 day (range, 0-14 days). Oral diet was reduced or suspended in 71.4%; analgesic and antiemetic drugs were required in 64% and 35.7% of patients, respectively. The variables independently associated with intolerance to refeeding were choledocholithiasis (hazard ratio [HR], 12.35; 95% confidence interval [CI], 2.98-51.19; P = 0.001), fasting time (HR, 1.33; 95% CI, 1.09-1.63; P = 0.005), refeeding with complete diet (HR, 4.93; 95% CI, 1.66-14.66; P = 0.04), length of symptoms before admission (HR, 1.004; 95% CI, 1.001-1.006; P = 0.012), and metamizole dose (HR, 1.11; 95% CI, 1.02-1.21; P = 0.014). CONCLUSIONS: Intolerance to refeeding is an infrequent event. We have identified several factors independently associated with intolerance.

Short- and long-term effects of a lactose-restricted diet and probiotics in children with chronic abdominal pain: a retrospective study.

OBJECTIVE: To determine the short- and long-term effect of treatment in children with chronic abdominal pain (CAP). METHODS: A database with the results of H(2) breath test of children with CAP was created. All children with an abnormal test result were included and classified as small intestinal bacterial overgrowth (SIBO) or lactose intolerant (LTI). SIBO was treated with probiotics and LTI with a lactose-restricted diet. CAP was evaluated 5 months and 15 months after the test. RESULTS: 37 children (41%) were included. 17 LTI children (94%) improved after 5 months and 11 children (61%) after 15 months (P<0.05). Seven SIBO children improved after 5 months and 4 children after 15 months. In the combination group all 4 children improved after 5 months and 3 children after 15 months. CONCLUSION: Children with CAP caused by LTI or SIBO had less CAP after 5 months. This positive effect persists only in half of the children.

Management of functional abdominal pain and irritable bowel syndrome in children and adolescents.

Functional abdominal pain (FAP) and irritable bowel syndrome (IBS) are among the most commonly diagnosed medical problems in pediatrics. Symptom-based Rome III criteria for FAP and IBS have been validated and help the clinician in making a positive diagnosis. The majority of patients with mild complaints improve with reassurance and time. For a distinct subset of patients with more severe and disabling illness, finding effective treatment for these disorders remains a challenge. Over the years, a wide range of therapies have been proposed and studied. The lack of a single, proven intervention highlights the complex interplay of biopsychosocial factors probably involved in the development of childhood FAP and IBS, and the need for a multidisciplinary, integrated approach. This article reviews the current literature on the efficacy of pharmacologic, dietary and psychosocial interventions for FAP and IBS in children and adolescents.
