abstract: FUNDAMENTAL: The difficulties to raise to a correct diagnosis in patients with human immunodeficiency virus infection and diarrhea, and the few cases reported of ulcerative colitis in the context of HIV infection.
  
  
  OBJECTIVE
  Description of 2 cases of ulcerative colitis in patients with HIV infection and the possibility of immunopathogenic relationship between them.
  
  
  METHODS
  The clinic history of the patients, the anatomopathological diagnosis after the colon biopsy and the determination of CD4 cells.
  
  
  RESULTS
  In case 1 the low level of CD4 cells didn't stop the aggressivity of ulcerative colitis. However, in both cases there was a good evolution of colitis after treatment although AIDS.
  
  
  CONCLUSIONS
  It is necessary to study more cases of inflammatory bowel disease in patients with HIV infection to determine the influence of the level of CD4 cells in the enteropathy's evolution.
