Teduglutide in pediatric intestinal failure: A position statement of the Italian society of pediatric gastroenterology, hepatology and nutrition (SIGENP). Dig Liver Dis 2022; 54:1320-1327. [PMID: 35654733 DOI: 10.1016/j.dld.2022.04.028] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Revised: 02/05/2022] [Accepted: 04/29/2022] [Indexed: 12/29/2022]
Abstract
In recent years, the spectrum of possible treatments for Intestinal Failure (IF)-Short Bowel Syndrome (SBS) has been enriched by the implementation of GLP-2 analogues. In Italy, teduglutide (Ted), an analogue of GLP-2, was approved in January 2021 by the Italian Regulatory Agency for Drugs (AIFA) for IF-SBS patients ≥1 year old. According to the Agency indications, Ted can now be prescribed by regional reference centers, with costs fully charged to the National Health Service. Following pediatric-use approval in our country and in light of scarce evidence in childhood, the pediatric network for IF of the Italian Society for Pediatric Gastroenterology, Hepatology and Nutrition (SIGENP) planned to share management methods of Ted in pediatric IF. The main purpose was to identify the best candidates from a cost-effective perspective. Thus, focusing on available literature and on expert opinions, the present position statement provides consensus-based recommendations on the use of Ted for pediatric gastroenterologists and nutritionists treating children with SBS.

Resveratrol modulates intestinal morphology and HSP70/90, NF-κB and EGF expression in the jejunal mucosa of black-boned chickens on exposure to circular heat stress. Food Funct 2016; 7:1329-38.

Abstract
The aim of this study was to investigate whether supplementation with resveratrol could alleviate intestinal injuries and to explore how resveratrol regulates heat shock protein (HSP)70, HSP90, nuclear factor kappa B (NF-κB) and epidermal growth factor (EGF) expression in the jejunal mucosa of black-boned chickens under circular heat stress. A total of 300 black-boned chicks of 42-d-old were randomly assigned to five treatment groups. The positive control chickens were kept in a normal-temperature (NT, 24 ± 2 °C) chamber and fed with a basal diet. The other four groups were kept in a circular high-temperature (HT, 37 ± 2 °C) chamber for 8 h and fed a basal diet supplemented with 0, 200, 400, or 600 mg per kg of resveratrol for 15 days. The results showed that the heat-stress responses damaged the villus structures of the jejunum and ileum, resulting in shortened intestinal villi, deepened crypts, and a reduced villus height to crypt depth (V/C) ratio and decreased the numbers of goblet cells and lymphocytes. Heat stress also caused increased mRNA and protein expression of HSP70, HSP90 and NF-κB, and reduced EGF in the jejunal mucosa. Dietary supplementation with 400 mg per kg of resveratrol improved the villus morphology, increased the numbers of goblet cells and lymphocytes, attenuated the mRNA overexpression of HSP70, HSP90 and NF-κB on the 6th, 10th and 15th day of heat stress (P < 0.05), and activated the expression of EGF (P < 0.05) in the jejunal mucosa. Resveratrol reduced protein expression of HSP70, HSP90 and NF-κB in the jejunal villi after 15 days of heat stress, and increased EGF expression from the lamina propria toward the epithelial cells of the villi. These results suggest that dietary resveratrol offers a potential nutritional strategy to improve the intestinal morphology and alleviate jejunum mucosa injuries by modulating the mRNA and protein expression of HSPs, and the epithelial growth factor and transcription factor in black-boned chickens subjected to circular heat stress.

Mok E, Hankard R. Glutamine supplementation in sick children: is it beneficial? J Nutr Metab 2011; 2011:617597. [PMID: 22175008 PMCID: PMC3228321 DOI: 10.1155/2011/617597] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2011] [Accepted: 09/28/2011] [Indexed: 12/14/2022] Open
Abstract
The purpose of this review is to provide a critical appraisal of the literature on Glutamine (Gln) supplementation in various conditions or illnesses that affect children, from neonates to adolescents. First, a general overview of the proposed mechanisms for the beneficial effects of Gln is provided, and subsequently clinical studies are discussed. Despite safety, studies are conflicting, partly due to different effects of enteral and parenteral Gln supplementation. Further insufficient evidence is available on the benefits of Gln supplementation in pediatric patients. This includes premature infants, infants with gastrointestinal disease, children with Crohn's disease, short bowel syndrome, malnutrition/diarrhea, cancer, severe burns/trauma, Duchenne muscular dystrophy, sickle cell anemia, cystic fibrosis, and type 1 diabetes. Moreover, methodological issues have been noted in some studies. Further mechanistic data is needed along with large randomized controlled trials in select populations of sick children, who may eventually benefit from supplemental Gln.

Diagnosis and pharmacological management of small intestinal bacterial overgrowth in children with intestinal failure. CANADIAN JOURNAL OF GASTROENTEROLOGY = JOURNAL CANADIEN DE GASTROENTEROLOGIE 2011; 25:41-5. [PMID: 21258668 DOI: 10.1155/2011/604643] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Indexed: 12/25/2022]
Abstract
The present article provides a general overview of the possible diagnostic procedures available for the management of small intestinal bacterial overgrowth in pediatric patients with intestinal failure. The focus is to address current diagnostic tools and understand their associated advantages and disadvantages based on a literature search. Culture of small intestinal aspirates, noninvasive breath tests and an emerging interest in quantitative bacterial DNA fingerprinting are discussed. Proper management is critical for preventing the recurrence of small intestinal bacterial overgrowth and its related complications. Antibiotic prophylaxis is one approach to the treatment of bacterial overgrowth in intestinal failure patients. Although treatment trials can be challenging in such a vulnerable population, more investigative clinical studies examining early diagnosis, more effective control of recurrence and the prevention of associated complications must be conducted.

Abstract
Extreme heat during certain days of the summer renders pigs susceptible to severe heat stress, which negatively affects their growth performance. We hypothesized that such heat stress impaired the small intestinal mucosa, a site responsible for nutrient absorption. To simulate heat stress, Chinese experimental mini-pigs were treated with 5 h of continual 40 degrees C temperature each day for 10 d in succession. Pigs were killed at 1, 3, 6 and 10 d after treatment, and small intestinal epithelia were sampled for histochemical examination and biochemical analyses. The duodenum and jejunum were seriously damaged within 3 d of initiation of treatment. Subsequent study of the process of jejunum recovery showed that the initiation of recovery started within 6 d following heat stress. Such damage was associated with the downregulation of epithelial growth factor signaling. In conclusion, heat stress induced short-term damage to the epithelium of porcine intestine. Because the intestinal epithelium is crucial for nutrient uptake, such damage should partially account for the impairment of growth performance of pigs under heat stress.
