A Case Report on Bovine Colostrum as a Potential Therapeutic Agent Alternative to Treat Gastrointestinal Complications of Common Variable Immunodeficiency.

Common variable immunodeficiency (CVID) or acquired hypogammaglobulinemia is one of the common forms of primary immunodeficiency, which primarily affects the respiratory tract, but is often associated with gastrointestinal complications. The pathophysiology is not fully understood, making a diagnosis of CVID difficult. The low levels of IgG and IgA and defective B cells make intravenous immunoglobulin (IVIG) therapy the mainstay of management. The present article describes the journey of a 41-year-old male suffering from CVID and severe recurrent uncontrollable gastrointestinal infections requiring Intravenous immunoglobulin therapy, which was successfully substituted with an alternative oral Hyperimmune Bovine Colostrum and Zinc combination for long term gastrointestinal disease control in a more affordable manner.
