Abstract
Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe adverse
drug reaction with a mortality rate near 10% characterized by erythematous cutaneous
eruption, multiorgan involvement, and hypereosinophilia. This case report highlights
a patient who developed DRESS in the setting of intravenous vancomycin and a vancomycin
and tobramycin-impregnated (PROSTALAC, DePuy Synthes, Warsaw, IN) functional spacer.
The spacer was placed during the revision of a left total knee replacement complicated
by a septic joint. To our knowledge, this is the third reported case of DRESS associated
with vancomycin-impregnated spacers. As DRESS is a potentially life-threatening reaction
and the principal treatment is withdrawal of the precipitating drug, it is important
to consider this clinical entity and discontinue all forms of the causative agent.
Patients with DRESS may develop a diffuse cutaneous eruption, respiratory failure,
acute kidney injury, elevated liver enzymes, lymphadenopathy, and/or hemodynamic instability
following intravenous infusion of antibiotics or placement of antibiotic-impregnated
spacers, beads, or bone cement. Interestingly, this patient had a prominent and progressive
erythematous eruption surrounding the left knee that improved after operative removal
of the spacer. At 6 week hospital follow-up, the patient's systemic signs and symptoms
had essentially resolved.
