Lack of benefit of intravenous immune globulin in a murine model of group A streptococcal necrotizing fasciitis.

摘要

Penicillin, clindamycin, and intravenous immune globulin (Venoglobulin-S; IVIG) alone and in combination were studied in a murine model of group A streptococcal necrotizing fasciitis. As assessed by bacterial clearance, treatment with IVIG was not significantly different from no treatment. All treatment regimens that contained penicillin or clindamycin were more effective (P<.05) than no treatment or treatment with IVIG alone. No significant differences were detected among results of treatment with penicillin, penicillin/clindamycin, penicillin/IVIG, clindamycin/IVIG, or all agents combined. Clindamycin alone was less effective than penicillin/IVIG (P=.02), penicillin/clindamycin (P=.009), clindamycin/IVIG (P=.04), or all agents combined (P=.02). No antagonism was observed with the addition of clindamycin or IVIG to penicillin.
