Vancomycin frequently induces hypersensitivity reactions including red man syndrome (RMS) and anaphylaxis. Lowering infusion rate with antihistamine premedication is usually effective to reduce RMS, however, desensitization should be considered for severe reactions not responding to usual measures. Here, we report a case of a patient with pyogenic spondylitis who had developed hypersensitivity reaction to vancomycin, got a full recovery with vancomycin desensitization. A 63-year-old man was transferred to our hospital for back pain, proved to pyogenic spondylitis. As methicillin-resistant Staphylococci aureus infection was suspected, vancomycin was administrated. But, he showed hypersensitivity reactions such as hypotension, dyspnea and severe flushing after vancomycin administration at previous hospital. Readministration of vancomycin at a lower infusion rate with premedication was tried. Three hours after vancomycin infusion, he developed fever, chills, rash and hypotension. Thrombocytopenia was occurred after administration of other antibiotics including cefazolin and teicoplanin. Vancomycin administration was attempted according to a rapid desensitization protocol. The infusion rate of vancomycin was increased to the standard rate. After the desensitization, he successfully completed the full course of treatment with vancomycin. Vancomycin desensitization could be the option for the vancomycin hypersensitivity when other antibiotics are not feasible. (Allergy Asthma Respir Dis 2013;1:168-171)
