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(R) Video Capsule System (Given Imaging, Yoqneam, Israel) in these patients.
Methods: After the 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 < 200/microl, gastrointestinal symptoms present. Group B: HIV-positive, CD subset4 < 200/microl, without gastrointestinal symptoms (n = 19 Group) C: healthy volunteers (n = 11).
Results: In group A there was a total of 30 pathological findings, 15 of which had 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 to the ligament of Treitz (p = 0.001). All capsules were recovered without any complication 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.
