Case Series Investigating the Clinical Practice Experience of Serum-Derived Bovine Immunoglobulin/Protein Isolate (SBI) in the Clinical Management of Patients with Inflammatory Bowel Disease
Abstract
Background: Serum-derived bovine immunoglobulin/protein isolate (SBI), a specially formulated oral protein source of >50% IgG and ~60% total immunoglobulins, has a multifaceted mechanism of action binding microbial components, maintaining gastrointestinal immune balance, managing gut barrier function and improving nutrient utilization. IBD animal models and a human refractory case study demonstrated that SBI can attenuate both inflammatory biomarkers and histological parameters in the bowel. Additionally, SBI is intended for the clinical dietary management of intestinal disorders due to limited/impaired capacity to ingest, digest, absorb or metabolize certain nutrients/foodstuffs or clinical dietary management of chronic loose and frequent stools. Given the known efficacy of SBI in gastrointestinal disorders and effects demonstrated in IBD animal models, SBI may help in the nutritional management of Inflammatory Bowel Disease (IBD) patients. Methods: In a clinical practice setting, we retrospectively evaluated seven ulcerative colitis (UC) and Crohn’s disease (CD) patients who incorporated SBI into their therapeutic regimens. All patients previously failed to adequately respond to conventional drug therapies. Their SBI response was assessed to determine its effect on further management in IBD patients. Results: The addition of SBI for nutritional management resulted in improved IBD symptoms including chronic loose and frequent stools. The UC patients reported resolution of…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
