[Gastrointestinal disease due to cytomegalovirus in patients infected with the human immunodeficiency virus].

OBJECTIVE

To describe all the clinical settings, endoscopic findings and response to therapy in a series of HIV-positive patients with biopsy proven gastrointestinal CMV disease.

PATIENTS

We retrospectively reviewed the medical records of all HIV-infected patients who underwent digestive endoscopies at our Hospital from June 1990 to October 1993.

RESULTS

Twelve (7.5%) of 158 HIV-positive patients had gastrointestinal CMV disease. Sites of prove infection included the esophagus (n = 6, 50%), stomach (n = 2, 17%), duodenum (n = 4, 33.3%), ileum (n = 1, 8.5%) and colon (n = 2, 17%). The most common endoscopic findings were focal or diffuse mucosal ulcers. Three patients had pseudotumoral mucosal lesions. Cytomegalic cells were observed in 11 patients (91.6%) and immunohistochemical staining was positive in 9 (81.8%) of 11 patients tested. Eight patients completed a course of treatment with ganciclovir or foscarnet and all of them showed clinical improvement. The median survival time of our AIDS patients with CMV gastrointestinal disease was 7 weeks (range 1-39 weeks).

CONCLUSIONS

Gastrointestinal CMV disease may damage any site of the digestive tract in AIDS patients. Routine histopathologic examination was better than immunohistochemical staining for the diagnosis. Treatment improves the clinical situation in most of them. The mean survival is low and it is related to the degree of immunosuppression.
