Summary

Objective

To estimate the relation between resistance to methicillin and virulence in strains ofStaph. aureus by estimating the survival at day 30.

Design

Case control analysis.

Setting

Inpatients at a major Cancer Referral Center.

Patients

21 patients with methicillin-resistantStaph. aureus (MRSA) bactaeremia and 45 patients with methicillin-susceptibleStaph. aureus (MSSA) bactaeremia, all treated with vancomycin.

Measurements and main results

Fewer MRSA than MSSA patients were neutropenic (p=0.04), but more MRSA patients were hospitalized in intensive care units (p=0.03), had had surgical episodes (p=0.06). MRSA patients also had more microbiological samples cultured (p=0.007). The outcome of the bacteriemic episodes in 14 MRSA and 14 MSSA patients matched for these four factors showed that blood cultures from MRSA patients remained positive significantly longer (p=0.04), but that survival and length of hospital stay were not significantly different.

Conclusions

These results do not indicate that methicillin-resistance inStaph. aureus is associated with increased virulence.
