cefotaxime and Stevens-Johnson-Syndrome

To report a case of possible cefotaxime-induced Stevens-Johnson syndrome (SJS).. A 72-year-old woman with an upper urinary tract infection developed erosions and blisters on the skin and the mucous membranes, as well as fever and prostration, soon after the administration of cefotaxime. This presentation is consistent with the features of SJS. Resolution of the clinical manifestations was observed after discontinuation of the drug; all other drugs, infections, or immunologic disorders that could have caused this syndrome were carefully excluded. An objective causality assessment revealed that SJS was possibly associated with the use of cefotaxime.. Although cephalosporins have been associated with an increased risk for SJS and cefotaxime has been suspected of being associated with SJS in a previous case-control study, this is the first full report for cefotaxime-related SJS in the literature. An immunologically mediated reaction may be the underlying mechanism.. Although cefotaxime administration seems to be the underlying cause of the SJS observed in our patient, establishment of a definite causal relationship requires additional cases and supportive data.

A series of antibiotics may be responsible for toxic epidermal necrolysis. We report two successive episodes of toxic epidermal necrolysis in the same patient. Drug imputability criteria designate a cross-reactivity between two antibiotics of different chemical classes but sharing the beta-lactam ring in common.. Descriptive case report and review of the literature.. Medical intensive care unit in a university medical center. PATIENT AND MAIN RESULTS: A 75-yr-old woman developed a first episode of toxic epidermal necrolysis (involving 40% of the body surface) after intake of cefotaxime, a third-generation cephalosporin. Perfusions of high-dose immunoglobulins rapidly improved the lesions, followed by partial reepithelialization in 5 days. Sepsis required the administration of meropenem, which is a carbapenem antibiotic. The epidermal destruction immediately recurred, with extension to previously uninvolved skin areas and fatal consequences.. The beta-lactam ring present in cephalosporins and carbapenems represents the putative chemical structure responsible for the presently reported cross-reactivity to two antibiotics of different classes. Drugs having any chemical similarity to the initial culprit compound should be strictly avoided when possible in the management of toxic epidermal necrolysis.
