HIV infection is linked to intestinal issues like villous atrophy, even with effective treatment. Capsule endoscopy revealed significant small bowel abnormalities in HIV patients, suggesting a persistent enteropathy.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Virology
Background:
- HIV infection can compromise intestinal barrier function.
- HIV enteropathy is a known complication, often independent of opportunistic infections.
- Small bowel abnormalities in HIV patients require further investigation.
Purpose of the Study:
- To assess intestinal mucosal changes in HIV-infected patients using capsule endoscopy.
- To compare findings with healthy controls.
- To investigate the prevalence of villous atrophy in HIV patients.
Main Methods:
- Capsule endoscopy (CE) was performed on HIV-infected patients and healthy controls.
- Patients with gastrointestinal opportunistic infections were excluded.
- CE findings were analyzed for mucosal abnormalities and villous atrophy.
Main Results:
- HIV-infected patients showed significantly more endoscopic findings (55%) than controls (10%).
- Villous atrophy was prevalent in 54% of HIV-infected patients.
- Villous atrophy persisted despite long-term antiretroviral therapy and restored CD4+ T cells.
Conclusions:
- Capsule endoscopy is effective in diagnosing villous atrophy in HIV patients.
- HIV infection is associated with significant small bowel mucosal abnormalities.
- Villous atrophy may persist in HIV patients even with successful antiretroviral therapy.

A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
