Abstract A variety of human disease conditions are associated with chronic intestinal disorders or enteropathies that are characterized by intestinal inflammation, increased gut permeability, and reduced capacity to absorb nutrients. Such disruptions in the homeostasis of the gastrointestinal (GI) tract can lead to symptoms of abdominal pain and discomfort, bloating, abnormal bowel function, and malabsorption of nutrients. While significant advances have been made in understanding the factors that influence the complex and fragile balance between the gut microbiota, intestinal epithelial cell integrity, and the underlying immune system, effective therapies for restoring intestinal balance during enteropathy are still not available. Numerous studies have demonstrated the ability of oral immunoglobulins to improve weight gain, support gut barrier function, and reduce the severity of enteropathy in animals. More recently, studies in humans provide evidence that serum-derived bovine immunoglobulin/protein isolate is safe and improves nutritional status and GI symptoms in patients with enteropathy associated with irritable bowel syndrome or infection with the human immunodeficiency virus. This review summarizes studies showing the impact of enteropathy on nutritional status and how specially formulated bovine immunoglobulins may help restore intestinal homeostasis and nutritional status in patients with specific enteropathies. Such protein preparations may provide distinct nutritional support required for the dietary management of patients who, because of therapeutic or chronic medical needs, have limited or impaired capacity to digest, absorb, or metabolize ordinary foodstuffs or certain nutrients, or other special medically determined nutrient requirements that cannot be satisfied by changes to the normal diet alone.
