简要总结
IBS is the most common diagnosis in new patients in our pediatric gastroenterology clinic, accounting for 36 % of all new patients. Pediatric IBS patients always have a problem with defecation, characterized either as diarrhea predominant or constipation predominant. About one third of pediatric IBS subjects have d-IBS. There are no FDA approved treatments for children with d-IBS. There is evidence that diarrhea predominant irritable bowel syndrome d-IBS may be caused by a mild inflammation in the intestinal lining. Oral serum-derived bovine immunoglobulin protein isolate (SBI) is a medical food, believed to treat mild inflammation in the small intestine associated with some cases of d-IBS, especially those arising after acute gastroenteritis. It improved pain and diarrhea in adults with d-IBS. Our aim is to determine if SBI improves the number of spontaneous bowel movements in children with d-IBS.
详细描述
The objectives of the study are to determine whether there is improvement in gastrointestinal symptoms (i.e., number of spontaneous bowel movements. abdominal pain, stool consistency, reduction in stool number, flatulence, urgency, incontinence), in laboratory parameters, and/or in psychosocial measures in subjects with d-IBS receiving 3 weeks of SBI.
This is a randomized, double-blind, placebo-controlled, weighted, pilot study evaluating effects of SBI (10 g per day), in children or adolescents with d-IBS.
The primary outcome will be change in the number of spontaneous bowel movements from the screening week compared to the final week. This information is gathered as part of the daily diary questions.
Secondary clinical outcome variables will include changes in abdominal pain, stool consistency, flatulence, urgency, and incontinence. Further clinical outcome variables will be change in number of spontaneous bowel movements during each treatment week compared to the screening week. Stool consistency will be assessed with the Bristol Stool Form Scale. Secondary laboratory outcome variables will include changes in stool calprotectin, stool lactoferrin, erythrocyte sedimentation rate, C-reactive protein, and platelet count from the screening week and final week. Secondary psychosocial outcomes will include data from Pediatric Quality of Life Inventory for Gastrointestinal Symptoms, and the Pediatric Functional Disability Index.
