Need to treat?
A 76-year-old patient presented with a two-week
history of watery diarrhoea. There was no history of
fever, abdominal pain nor bloody stools. Blood analysis
showed inflammation (C-reactive protein of 160 mg/L,
reference <5 mg/L) and a normal complete blood count.
Faecal culture showed no pathogens. The patient was
treated with a three-day course of azithromycin 500 mg
daily without improvement. Subsequently, a colonoscopy
was performed, which showed no macroscopical
abnorma-lities. Randomly taken biopsies revealed a thin
blue fringe on the colonic epithelium (Figure 1).
