Objetivo: Analizar la influencia de la dieta en la microbiota intestinal en la enfermedad inflamatoria intestinal, así como concientizar a los profesionales de la salud en la importancia de la terapia a partir de la dieta, como pilar esencial en el control de esta enfermedad digestiva crónica. Metodología: Se realizó una búsqueda en bases de datos como: Scielo, Pubmed/Medline, Ebsco, Clinical Key, Springer, Web of Science, Infomed, se incluyeron revistas, libros, repositorios de tesis, sitios web de especialidades. Desarrollo: En los pacientes con enfermedad inflamatoria intestinal existe una disbiosis que contribuye potencialmente a una respuesta inmune proinflamatoria. Conclusiones: El equilibrio entre el huésped y su microbiota intestinal es esencial para el desarrollo inmunológico óptimo; la modificación de la dieta y la flora bacteriana intestinal son dianas potenciales en el tratamiento y prevención de la misma (AU)

ABSTRACT Background: Inflammatory bowel disease includes idiopathic ulcerative colitis and Crohn's disease. In the pathogenesis are present genetic and environmental factors such as alteration of luminal bacteria and increased intestinal permeability, factors that alter the intestinal immunity, these causes of gastrointestinal injury. Objective: To analyze the influence of diet on intestinal microbiota in inflammatory bowel disease, as well as to increase awareness among health professionals about the importance of diet-based therapy as an essential pillar in the control of this chronic digestive disease. Methodology: A search was made in databases such as: Scielo, Pubmed / Medline, Ebsco, Clinical Key, Springer, Web of Science, Infomed, magazines, books, thesis repositories, and specialty websites. Development: In patients with inflammatory bowel disease there is a dysbiosis that potentially contributes to a proinflammatory immune response.

Navy and black bean supplementation attenuates colitis-associated inflammation and colonic epithelial damage.

The enriched levels of nondigestible fermentable carbohydrates and phenolic compounds found in common beans can exert immunomodulatory effects within the colon that improve gut health and mitigate the severity of colitis-associated inflammatory pathology. Prior to acute colitis onset, C57Bl/6 mice were prefed isocaloric 20% cooked navy bean (NB) or black bean (BB) diets for 3 weeks and switched to control basal diet (BD) 24 h prior to colitis induction via 5-day exposure to dextran sodium sulfate (2% w/v in drinking water)+3 days of fresh water. The severity of the acute colitis phenotype was attenuated by bean prefeeding, evidenced by reduced colon tissue inflammatory transcription factor activation (NFκB, STAT3) and inflammatory mediator levels in the colon (IL-1ß, IL-6, IL-18 and MCP-1) and serum (TNFα, IL-6, IL-1ß, MCP-1) versus BD (P≤.05). Additionally, biomarkers of enhanced wound repair responses were increased by bean prefeeding including colon tissue protein levels of IL-22, IL-27 and activated (i.e., GTP-bound) Cdc42 and Rac1 versus BD (P≤.05). mRNA expressions of genes involved in normal colonic epithelial function and the promotion of epithelial barrier integrity, defense and/or restitution and wound closure including MUC1, RELMß, IgA and REG3γ were all increased in NB and BB prefed mice versus BD (P≤.05). Collectively, bean supplementation prior to colitis induction (i.e., mimicking disease relapse) primes the colonic microenvironment to attenuate the severity of the colitis inflammatory phenotype and maintain aspects of epithelial barrier function.

Oats and bowel disease: a systematic literature review.

Whole-grain foods such as oats may protect against colorectal cancer and have benefits on inflammatory bowel disease and coeliac disease. The present study aimed to systematically review the literature describing intervention studies that investigated the effects of oats or oat bran on risk factors for bowel disease. A literature search was conducted using Embase, Medline and the Cochrane library, which identified 654 potential articles. Thirty-eight articles describing twenty-nine studies met the inclusion criteria. Two studies carried out in participants with a history of colorectal adenomas found no effects of increased oat-bran intake on indirect risk makers for colorectal cancer. One of two interventions with oat bran in patients with ulcerative colitis showed small improvements in the patients' conditions. Most of the eleven studies carried out in adults with coeliac disease showed no negative effects of uncontaminated oat consumption. The fourteen studies carried out in volunteers with no history of bowel disease suggest that oats or oat bran can significantly increase stool weight and decrease constipation, but there is a lack of evidence to support a specific effect of oats on bowel function compared with other cereals. A long-term dietary intake of oats or oat bran could benefit inflammatory bowel disorders, but this remains to be proven. A protective effect on colorectal adenoma and cancer incidence has not yet been convincingly shown. The majority of patients with coeliac disease could consume up to 100 g/d of uncontaminated oats, which would increase the acceptability of, and adherence to, a gluten-free diet.

Attenuation of histopathological alterations of colon, liver and lung by dietary fibre of barley Rihane in azoxymethane-treated rats.

This study was carried out to determine the effect of dietary fibre (DF) of barley Rihane (BR) in the attenuation of colon, liver and lung histopathology alterations induced by azoxymethane (AOM) in rats. Rats were fed a control (C) or experimental diet containing 30% of BR. The intended rats for cancer treatment received two successive subcutaneous injections of azoxymethane (AOM) at 20mg/kg body weight. The colons were analyzed for crypt multiplicity after 12 weeks of treatment. A histological study of the colon, liver and lungs was determined. The results showed that the BR diet significantly reduced the number of aberrant crypt per focus and altered their distribution. In addition, DF of BR increased significantly the mucus secretion compared to control group. The use of the AOM as colon specific carcinogen substance altered the liver and lung architectures, whereas the presence of DF of BR could be a protective factor for these organs.

Comparison of early mobilization and diet rehabilitation program with conventional care after laparoscopic colon surgery: a prospective randomized controlled trial.

PURPOSE: Although laparoscopic surgery may permit earlier recovery compared with open surgery, no published randomized controlled trial has investigated the benefit of a multimodal rehabilitation program after laparoscopic colonic resection. This study aimed to evaluate the efficacy of a rehabilitation program after laparoscopic colon surgery in the context of a randomized controlled trial. METHODS: Between September 2007 and October 2009, 100 patients who had received laparoscopic colon surgery were selected for the study and randomly assigned on a 1:1 basis to a rehabilitation program group with early mobilization and diet (n = 46) or conventional care group (n = 54). The rehabilitation program group received early oral feeding, early ambulation, and regular laxative. The primary outcome was recovery time, measured with criteria of tolerable diet for 24 hours, safe ambulation, analgesic-free, and afebrile status without major complications. Secondary outcomes were postoperative hospital stay, complications, quality of life by Short Form 36, pain by visual analog scale, and readmission. This study was registered (ID number NCT00606944, http://register.clinicaltrials.gov). RESULTS: Recovery time was shorter in the rehabilitation program group than in the conventional care group (median (interquartile range), 4 (3-5) d vs 6 (5-7) d, respectively; P < .0001). There was no difference in postoperative hospital stay between the 2 groups (rehabilitation program group, 7 (6-8) d vs conventional care group, 8 (7-9) d; P = .065). There was no difference in complication rates between the rehabilitation program group and conventional care group (10.9% vs 20.4%, respectively; P = .136). Quality of life and pain were similar in both groups. There were no readmissions or mortality. CONCLUSIONS: A rehabilitation program with early mobilization and diet after laparoscopic colon surgery results in reduced recovery time without increased complications. These results suggest that a multimodal rehabilitation program may increase the short-term benefits after laparoscopic colon surgery.

Oats supplementation prevents alcohol-induced gut leakiness in rats by preventing alcohol-induced oxidative tissue damage.

We reported previously that oats supplementation prevents gut leakiness and alcoholic steatohepatitis (ASH) in our rat model of alcoholic liver disease. Because oxidative stress is implicated in the pathogenesis of both alcohol-induced gut leakiness and ASH, and because oats have antioxidant properties, we tested the hypothesis that oats protect by preventing alcohol-induced oxidative damage to the intestine. Male Sprague-Dawley rats were gavaged for 12 weeks with alcohol (starting dose of 1 g/kg increasing to 6 g/kg/day over the first 2 weeks) or dextrose, with or without oats supplementation (10 g/kg/day). Oxidative stress and injury were assessed by measuring colonic mucosal inducible nitric-oxide synthase (iNOS) (by immunohistochemistry), nitric oxide (colorimetric assay), and protein carbonylation and nitrotyrosination (immunoblotting). Colonic barrier integrity was determined by assessing the integrity of the actin cytoskeleton (immunohistochemistry) and the integrity of tight junctions (electron microscopy). Oats supplementation prevented alcohol-induced up-regulation of iNOS, nitric oxide overproduction in the colonic mucosa, and increases in protein carbonyl and nitrotyrosine levels. This protection was associated with prevention of ethanol (EtOH)-induced disorganization of the actin cytoskeleton and disruption of tight junctions. We conclude that oats supplementation attenuates EtOH-induced disruption of intestinal barrier integrity, at least in part, by inhibiting EtOH-induced increases in oxidative stress and oxidative tissue damage. This inhibition prevents alcohol-induced disruption of the cytoskeleton and tight junctions. This study suggests that oats may be a useful therapeutic agent--a nutraceutical--for the prevention of alcohol-induced oxidative stress and organ dysfunction.

Pneumatosis coli in a dog.

A 17-year-old, castrated male Maltese was presented with chronic polyphagia and a 2-week history of tenesmus, diarrhea, hematochezia, weight loss, and ribbon-like feces. Pneumatosis coli was diagnosed by abdominal radiography. Concurrent hyperadrenocorticism was suspected. The clinical signs of colorectal disease resolved within 2 days of initiating a lowresidue diet and oral metronidazole. Pneumatosis coli should be considered as a differential diagnosis for colorectal disease in dogs.

[Efficacy of cow's kumiss in the treatment of large intestine dysbacteriosis and its impact on tolerability of antituberculosis agents in patients with respiratory tract tuberculosis]. / Effektivnist' ispol'zovaniia korov'ego kumysa dlia lecheniia disbakterioza tolstoi kishki i ego vliiania na perenosimost' protivotuberkuleznykh preparatov u bol'nykh tuberkulezom organov dykhaniia.

Dysbacteriosis of the large intestine is one of severe complications of long-term use of antituberculosis agents in the treatment of respiratory tract tuberculosis that results in a significant decrease of tolerability of antituberculosis agents, persistence of tuberculosis intoxication and slower involution of the tuberculosis process in the lungs. When the complex treatment with antituberculosis agents was accompanied by the use of cow's kumiss for correction of the large intestine dysbacteriosis, the intoxication signs disappeared in 12% of the patients in the main group, while in the patients of the control group the level of the intoxication syndrome increased twice. The rate of the tuberculosis lesions regression evident from the lung roentgenograms was 2.7-fold higher in the main group vs. the control (62 and 23% respectively). The indices of the lung functional capacity recovery in the patients of the main group vs. the control were also higher (41 and 33% respectively). Hepatic toxic reactions in the patients not given cow's kumiss for correction of dysbacteriosis were 8 times more frequent vs. the control. The results of the study made it possible to develop recommendations for phthisiologists in the use of cow's kumiss as one of the methods of pathogenetic therapy in complex treatment of patients with respiratory tract tuberculosis in sanatoria.

Does rich fiber diet accelerate the healing process of low-output colorectal fistulas?

The occurrence of an anastomotic leakage is a major therapeutic concern in colorectal surgery. Considering the outflow level of the fistula, a defunctioning stoma may be necessary to obtain closure. When the outflow is low and the intestinal transit is not interrupted, a colostomy is not mandatory but the healing process can be long. Here the author presents three consecutive cases of low output fistula treated by feeding with an enriched fiber diet. Closure of the fistulae occurred in a few days. The rationale of this alternative treatment is discussed.

Low residue nutritional supplementation as an adjunct to mechanical preparation for surgical treatment of the colon.

The mechanical and nutritional efficacy of a low residue nutritionally complete liquid diet was evaluated as an adjunct for colonic preparation in patients undergoing large intestinal operations. The complete liquid diet was identical to more traditional clear liquid diets in terms of cleanliness of the intestine and general profile of bacterial flora. This complete diet was well accepted by patients and was superior in its provision of energy, protein, vitamins, minerals and nitrogen. The use of this low residue supplemental diet was associated with a statistically earlier return of intestinal function and a trend toward shorter length of hospitalization. The results of this study indicate that low residue nutritionally complete liquid diets not only offer comparable mechanical cleanliness but also outstanding nutritional advantages not obtained with traditional preparatory diets.
