Toxic epidermal necrolysis (TEN) is a rare complication after allogeneic hematopoietic stem-cell transplantation and carries high mortality rates. Graft-vs-host disease (GVHD) is also a life-threatening complication, and potentially indistinguishable from TEN because of similar clinical symptoms. However, current therapeutic recommendations differ between these two conditions, thereby posing a diagnostic dilemma. The authors, herein, present a complicated postoperative course after bone marrow transplantation with concurrent gastrointestinal and hepatic GVHD, and extensive epidermolytic disease compatible with both severe cutaneous GVHD and TEN. An early consult to a specialized burn service, and prompt transfer to a burn intensive care unit with extensive supportive care and nursing are of paramount importance in the management of immunosuppressed patients with TEN. Better understanding of the pathogenesis of TEN and GVHD after hematopoietic stem-cell transplantation, further treatment strategies, and more advanced diagnostic techniques are still needed to achieve acceptable mortality rates.

A 48-year-old female, who was found unresponsive and suffered inhalation injury secondary to a house fire, was transferred to our burn center for definitive treatment. Post tracheostomy, the patient became febrile and tachycardic. On hospital day (HD) 5, the patient expressed thick yellow secretions during suctioning and diffuse rhonchi was noted on physical exam. Blood cultures and a culture from the broncheo-alvelolar lavage grew Gram-positive cocci in clusters and the patient was started on empiric vancomycin. Despite aggressive vancomycin dosing (1750 mg intravenously every 6 h), the patient’s status continued to deteriorate. The organism was identified as methicillin-resistant Staphylococcus aureus (MRSA) with a vancomycin minimum inhibitory concentration (MIC) of 2 mg/L. Based on the potential for drug–drug interactions with linezolid, the patient was started on ceftaroline fosamil (MIC = 0.5 mg/L) 600 mg intravenously every 8 h with a prolonged 2-h infusion to anticipate suboptimal concentrations secondary to thermal burn injury. Post change in antibiotic therapy, a rapid clinical improvement was observed with the patient becoming afebrile at 48 h after initiation of ceftaroline. The patient completed a total of 14 days of ceftaroline therapy and was subsequently weaned from the ventilator on HD 22 and decannulated 2 days later. To our knowledge, this is the first report of the use of ceftaroline for the treatment of MRSA pneumonia in a patient with thermal injury.Electronic supplementary materialThe online version of this article (doi:10.1007/s40121-015-0096-4) contains supplementary material, which is available to authorized users.
