We examined the clinical features of 14 men (mean age 72 years) with postoperative enteritis caused by methicillin-resistant Staphylococcus aureus (MRSA). The patients had all undergone surgery for the treatment of digestive diseases and had received antibiotic prophylaxis consisting of an extended-spectrum cephem. Diarrhea appeared a mean of 3.3 days postoperatively and lasted for 5 days on average. In severe cases organ insufficiency was involved. Coagulase-positive staphylococci were the predominant organisms isolated from watery diarrhea. In 13 of 14 patients, coagulase type II isolates producing enterotoxins A, C and toxic shock syndrome toxin-1 (TSST-1) with enterotoxin A, C, and tst genes were isolated. These strains were sensitive to vancomycin and arbekacin; however, they were highly resistant to many other antibiotics. We also investigated the effects of a glucocorticoid hormone and gamma globulin on production of tumor necrosis factor-α (TNF-α) and interleukin-2 (IL-2) obtained from healthy volunteers. TNF-α and IL-2 production was enhanced by TSST-1 and the supernatant of Iscove-modified dulbecco medium, in which coagulase type II isolates producing enterotoxins A, C and TSST-1 with enterotoxin A, C were cultured for 24h. Both glucocorticoid hormone and gama globulin suppressed TNF-α and IL-2 production, thus suggesting that these drugs may be effective in treating postoperative MRSA enteritis.
