Serum interleukin 15 (IL-15) levels were measured in 77 patients who were consecutively admitted to our intensive care unit. Postoperative enterocolitis occurred in four patients and Methicillin-resistant Staphylococcus aureus (MRSA), but not Clostridium defficile, was identified in the faecal specimens from these patients. The IL-15 levels in the patients with MRSA enterocolitis were significantly elevated compared with those of other MRSA infections without enterocolitis including pneumonia (n = 6) and cholangitis (n = 1), and other MRSA non-colonized patients (n = 66) (21.2 ± 5.2 pg/ml vs 4.3 ± 0.2, 4.3 ± 0.5). Notably, an increase in serum IL-15 was observed just before clinical manifestation of severe diarrhoea. Our findings suggest that IL-15 may be associated in the pathogenesis of postoperative enterocolitis and its serum level may be a severity indicator of the disease.
