However, the relationship between CVID and Enteropathy is still unclear. CVID is characterized by decreased levels of of two or more serum immunoglobulin (Ig) isotypes and the presentation of reoccurring infections specifically in the respiratory tract. Gastrointestinal symptoms are widespread with CVID patients as exhibited in as many as 50% of patients presenting with chronic diarrhea. A team of doctors evaluated the medical files of 50 CVID patients who exhibited gastrointestinal symptoms to determine the “clinical and hitopathological features of the enteropathy associated with CVID”. Fifteen patients were excluded from the study because they did not meet the recognized criteria for CVID. Data was collected from all patients and included, gender, age, symptoms, body mass index (BMI), as well as parasitological stool testing. Blood samples were taken from each test patient including hemogram, serum protein electrophoresis and measurements of serum folic acid, vitamin B12, iron, and calcium. The doctors found the mean age for initial CVID diagnosis to be 36.8 years. Four of the patients were discovered to have a family history of immunodeficiency. 40% of the patients that were tested were determined to have immunodeficiency as revealed by their digestive symptoms. Chronic diarrhea was observed as the most common gastrointestinal symptom with a rate of 92% of the patients studied. Gluten-free diet was initiated by 12 patients with villous atrophy, but clinical improvements and partial villous healing only occurred in two patients. Interestingly, the two patients presenting with celiac antibodies, did not show an improvement of symptoms. All patients showed positive improvements from steroid therapy. Furthermore, as a result of this study, the observing doctors concluded, that of the CVID patients exhibiting gastrointestinal symptoms, histological lesions were found in around 80% of the biopsies taken from the colon, stomach, or small bowel. The enteropathy corresponding with CVID was found to have has many features that differentiate it from other etiopathological conditions including celiac disease. While replacement Ig therapy was demonstrated to be inadequate for improving gastrointestinal symptoms, steroids, specifically budesonide,were proven successful in reducing inflammation and restoring mucosal architecture.
