Spontaneous bacterial peritonitis in Wilson's disease

Spontaneous bacterial peritonitis associated with Wilson's disease has been previously reported in only one case. We report two cases where this infection developed and seriously complicated the course of illness. As with spontaneous bacterial peritonitis occurring with other underlying diseases, early diagnosis and treatment are critical to improved outcome. Recognition that it can occur with Wilson's disease is important, and paracentesis should be performed without delay when suspicious features are present.
