Colonic vasculitis in a woman with end-stage kidney disease and HIV infection

We present the case of a 57-year-old female with bloody diarrhea, fever and abdominal pain. Her medical history included human immunodeficiency virus (HIV) infection with an undetectable viral load and end-stage kidney disease secondary to HIV on dialysis. At admission, she had a painful abdomen, no skin lesions and bloody stools in the rectal examination. Laboratory findings included a white blood cell count of 12,900 x 103 cells/μl, CD4 counts of 243 cells/μl and C-reactive protein of 24.5 mg/dl. Serologies, cytomegalovirus and PCR SARS-CoV-2 were negative.
