Wireless capsule endoscopy for the detection of small bowel diseases in HIV-1-infected patients

Abstract

Abstract Background and Aims In HIV-infected patients, manifestations of the disease are common in the gastrointestinal tract. The objective of our study was to evaluate the diagnostic yield of the Given® Video Capsule System (Given Imaging, Yoqneam, Israel) in these patients. Methods After exclusion of GI-tract stenosis by anamnestic exploration, 49 patients were included into the study. Stratification: Group A (n = 19): HIV-positive, CD4 cell count 4 Results In group A there was a total of 30 pathological findings, 15 of which with therapeutic implications. In group B, there was a total of 22 pathological findings, 5 relevant for therapy. In group C there was a total of 13 pathological findings, 3 with therapeutic relevance. In 89% (group A) vs. 26% (group B), pathological findings were detected distal the ligament of Treitz (p = 0.001). All capsules were recovered without complications after 12 to 96 h from the stool. Conclusion Wireless capsule endoscopy of the small intestine should be considered for HIV-infected patients with marked immunosuppression and gastrointestinal symptoms.
