TLDR
It is found that mild to severe GI pathology was common in CGD and microgranulomas, pigmented macrophages, and eosinophilia are not associated with acute (neutrophilic) inflammation.Abstract:
Gastrointestinal (GI) involvement in chronic granulomatous disease (CGD), a rare genetic immunodeficiency, mimics other inflammatory bowel diseases. We report GI pathology from 87 CGD patients seen at the NIH Clinical Center, with vague to severe clinical symptoms, in whom biopsies (313) had been evaluated (esophagus [23], stomach [71], small bowel [52] including duodenum [39], ileum [12], and jejunum [1], and colon [167]). Additionally reviewed was GI tissue from 15 autopsies. In our patient cohort, the mean age was 22 years (age range, 3 to 44 y; 2:1 male to female ratio). There were pathologic changes in 83/87 (95%) patients; with colon being the most commonly involved site and esophagus the least. There were microgranulomas in 53/87 (61%), pigmented macrophages in 64/87 (74%), tissue eosinophilia in 31/87 (36%), and chronic and/or acute inflammation in 57/87 (66%) patients. A subset of patients had villous shortening in the duodenum (8/39) and ileum (5/12). We identify microgranulomas in 76/167 (46%) colon, 12/52 (23%) small bowel, and 4/71 (6%) gastric biopsies; pigmented macrophages in 109/167 (65%) colon and 7/52 (13%) small bowel biopsies and 14/15 autopsies; chronic and/or acute inflammation in 97/167 (58%) colon, 13/52 (25%) small bowel, 42/71 (59%) gastric, and 5/23 (22%) esophageal biopsies; tissue eosinophilia in 43/167 (26%) colon, 7/52 (13%) small bowel, and 2/71 (3%) gastric biopsies. Only 4/87 (5%) patients had normal histology. No infectious etiology was identified in the majority of inflammatory lesions. We found that mild to severe GI pathology was common in CGD. In addition, microgranulomas, pigmented macrophages, and eosinophilia are not associated with acute (neutrophilic) inflammation.read more

TL;DR: The purpose of this paper is to review the imaging findings of CGD that can manifest throughout the body and to recognize the pattern of infection, inflammation, and granuloma formation leading to a diagnosis.

TL;DR: GI involvement is a common and recurring problem in CGD, especially in those with X-linked inheritance, and should be sought in patients who have CGD with abdominal pain, growth delay, or hypoalbuminemia.

Chronic Granulomatous Disease
TL;DR: Chronic granulomatous disease is worthy of attention for its historical interest and because it is a disease for which expert management is imperative.
