A sixty-five-year-old man with rash, fever, and generalized weakness
Abstract:Diffuse erythematous rash accompanied by high-grade fever, eosinophilia, and facial edema can be caused by a variety of infective, allergic, or systemic etiologies. We present a case of 65-year-old man with septic arthritis, who had a vancomycin antibiotic spacer placed in his infected knee and was also started on intravenous (i.v.) vancomycin. After 2 weeks he presented with sudden onset of fever and generalized weakness. Physical examination was significant for tachycardia and hypotension, facial edema, diffuse erythematous rash, and bilateral wheezing. Laboratory values indicated acute renal insufficiency associated with eosinophiluria and significant peripheral eosinophilia. Septic shock was highly suspected and he was treated with i.v. fluids and broad-spectrum antibiotics. Despite aggressive management his condition rapidly deteriorated with persistent of shock state, increase in facial edema, and rash. Other suspected etiologies included hypersensitivity reactions to i.v. antibiotics (piperacillin/tazobactam) or vancomycin, systemic vasculitis, or idiosyncratic reactions to medications such as Stevens-Johnson syndrome. The patient was started on high-dose i.v. steroids, which led to improvement of his clinical condition. Clinical presentation of adverse drug reactions is highly variable and may present as potentially life-threatening multiorgan failure. Early recognition of the etiology and removing the offending agent is important to improve the outcome.
