Entera Health, Inc. Announces the Publication of a Case Series Report on the Use of Orally Administered Serum-Derived Bovine Immunoglobulin/Protein Isolate (SBI) in the Clinical Management of Patients with Inflammatory Bowel Disease (IBD).

Entera Health, Inc. announced today the publication of a clinical case series report in the Journal of Therapeutic Advances in Gastroenterology that summarizes a retrospective evaluation of 45 patients with either ulcerative colitis (UC) or Crohn’s disease (CD) who had EnteraGam® (serum-derived bovine immunoglobulin/protein isolate, SBI) incorporated into their therapeutic regimens after failing to respond adequately to conventional therapies. An improvement in clinical symptoms was reported by 49% of IBD patients after just one week of SBI therapy, which increased to 76% of patients reporting symptom improvement after 12 weeks of SBI therapy. The odds ratio from a regression model demonstrated that IBD patients were 2.8 times more likely to report clinical improvement in symptom scores with the addition of SBI to their therapeutic regimens [95% confidence interval (CI) 1.266–6.016, p = 0.011]. Disease management was not significantly associated with age, gender, race or disease state and no side effects were reported.

The study was performed as a single center, retrospective chart review of IBD patients [CD, n = 38; UC, n = 7] who experienced limited to no response to traditional pharmaceutical therapies in controlling symptoms and subsequently received SBI (5 g/day) for nutritional support. Patients were contacted at least monthly to assess their response to SBI on symptom management as measured by a Likert scale (0 = none; 1 = minimal; 2 = moderate; 3 = significant; 4 = complete). The overall group response and percent improvement to SBI was determined over 12 weeks. Authors include: Ira Shafran, MD (Winter Park, FL), Patricia Burgunder, ARNP (Winter Park, FL), David Wei, PhD (Cary, NC), Hayley Young, PhD (Cary, NC), Gerald Klein, MD (Cary, NC), and Bruce Burnett, PhD (Cary, NC).


About Inflammatory Bowel Disease (IBD)

Inflammatory Bowel Disease (IBD) is a chronic inflammatory condition resulting from an immune dysregulation of the intestinal tract, the cause of which remains to be determined [1]. In the US alone, it is estimated that IBD affects more than 1.6 million individuals [2]. The immune dysregulation that occurs in patients with IBD results in two distinct disease states: ulcerative colitis (UC) and Crohn’s disease (CD). Ulcerative colitis is a disease of unknown etiology that produces chronic inflammation of the colon, whereas CD is relapsing inflammatory condition affecting any part of the gastrointestinal tract. Patients with UC often present with symptoms of bloody loose stools, abdominal cramps, and fatigue [3], while patients with CD frequently present with symptoms of abdominal pain, fever, and clinical signs of bowel obstruction or bloody loose stools or mucus [4]. Evidence suggests that many factors that contribute to IBD, which partly explains why current treatment methods target the clinical symptoms associated with the inflammatory and immune response in an effort to avoid the need for surgery and address complications associated with IBD [1]. Since there is no cure for IBD, current treatment goals recommended by the Crohn’s and Colitis Foundation of America are to induce remission, maintain remission by preventing flare-ups, and improve overall quality of life.
