Severe cholestatic jaundice associated with piroxicam.

A 62-year-old man with rheumatoid arthritis developed jaundice while taking piroxicam. A full evaluation including ultrasound, computerized tomography, endoscopic cholangiography, and liver biopsy confirmed the diagnosis of intrahepatic cholestasis. The patient's jaundice and all other liver function abnormalities normalized 4 months after he discontinued taking piroxicam. This is the first case report in the United States of severe liver toxicity associated with piroxicam. The six cases in the English-language literature are reviewed, featuring the presentation, patterns of liver injury, and outcome in each. Piroxicam should be considered as a potential cause of cholestatic jaundice when other more common etiologies have been excluded.

Whipple's disease can mimic chronic AIDS enteropathy.

Previous case reports have demonstrated that the intestinal pathology of Mycobacterium avium-intracellulare (MAI) infection in the acquired immune deficiency syndrome (AIDS) has a light microscopic appearance similar to Whipple's disease. This case report describes a 52-yr-old male patient with a clinical picture suggestive of AIDS, including diarrhea, weight loss, oral thrush, and intestinal cryptosporidiosis. The intestinal biopsy showed light microscopic features compatible with either MAI or Whipple's disease, but electron microscopy confirmed the presence of the Whipple bacillus. Markers of human immunodeficiency virus (HIV) infection were absent. Although immune abnormalities have been reported in Whipple's disease, this is the first report of opportunistic infections complicating this condition. A useful clinical pearl emerges from this and other cases: AIDS can mimic Whipple's disease; Whipple's disease can mimic AIDS.
