Penicillin Desensitization in the Treatment of Syphilis During Pregnancy

ABSTRACT

The objective of this study was to compare patients' hospital course, complications, and charges for oral and intravenous (i.v.) desensitization regimens for the treatment of syphilis in the penicillin-allergic gravida. We performed a retrospective search of medical records at two tertiary-level teaching hospitals and reviewed the hospital course of penicillin-allergic gravidas who underwent penicillin desensitization. Between August 1988 and December 1995, 16 procedures for penicillin desensitization were carried out: 11 oral procedures, and 6 i.v. procedures. There were no significant differences between the patients in the oral and i.v. desensitization groups with respect to demographic characteristics, duration of time in a monitored bed, or length of hospital stay. The oral regimen was less expensive than the i.v. regimen ($144.06 vs. $319.48). In our experience, oral and i.v. regimens provide effective desensitization for the treatment of syphilis in penicillin-allergic gravidas. However, the oral route offers ease of administration and substantial cost savings, making it the preferred method.
