Objective
In 2005 the Cystic Fibrosis (CF) Foundation recommended that children with CF maintain a body mass index (BMI) ≥50th percentile. Our study evaluated if gastrostomy (GT) placement increases the likelihood of reaching that goal compared to a standardized nutrition protocol.
Study design
Retrospective study of 20 children with CF ages 2–20 years with GTs placed from 2005–2010. Each case was pair-matched on age, sex, pancreatic status, BMI and lung function with a non-GT child with CF. Outcome measures included nutritional status and lung function at 6 months and 1 year.
Results
At baseline, mean±SD BMI Z-scores were similar (cases −1.19±0.60, controls −1.10±0.50; p=0.10). Cases had a significant 6-month increase in mean BMI Z-score to −0.29±0.84 compared to −1.02±0.67 for controls (p<0.001). By 1 year, the change in mean BMI Z-score was less different (cases −0.41±0.76, controls −0.71±0.51; p=0.07). Both groups had stable lung function. From exact logistic regression analysis, the odds ratio for cases compared to controls of reaching BMI≥50th percentile was 9.70 (95% CI:1.05–484.7;p=0.04) at 6 months and 3.65 (95%CI:0.69–25.86;p=0.16) at 1 year.
Conclusion
Our study suggests that children with CF who receive GTs are more likely to achieve BMI≥50th percentile than matched children without GTs.
The analysis of twins and siblings with CF indicates a prominent role for genes other than CFTR to BMI variation. Specifically, regions on chromosomes 1 and 5 appear to harbor genetic modifiers of substantial effect.
Ulcerative colitis is a chronic inflammatory bowel disease that can lead to derangements in the growth, nutritional status, and psychosocial development of affected children. There are several medical options for the induction and maintenance of disease remission, but the benefits of these medications need to be carefully weighed against the risks, especially in the pediatric population. As the etiology of the disease has become increasingly understood, newer therapeutic alternatives have arisen in the form of biologic therapies, which are monoclonal antibodies targeted to a specific protein or receptor. This review will discuss the classical treatments for children with ulcerative colitis, including 5-aminosalicylates, corticosteroids, thiopurine immunomodulators, and calcineurin inhibitors, with a particular focus on the newer class of anti-tumor necrosis factor-α agents.
Ulcerative colitis is a chronic, idiopathic, inflammatory disease of the colon and rectum that may be associated with growth failure, nutritional derangements and psychosocial ramifications in affected children. Multiple medical options are available to achieve disease remission; however, some of these medications can have unwanted side effects, especially in younger patients. With increased understanding of the etiology of the disease, newer therapeutic alternatives have arisen in the form of biologic therapies, namely monoclonal antibodies targeted to a specific protein or receptor. Specifically, infliximab, an anti-TNF-α agent, has been shown to be safe and effective for the treatment of moderate-to-severe pediatric ulcerative colitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
