“I have a fever and chills.”
Scarlet Hives is a 60-year-old woman with a history of IgG kappa multiple myeloma who is undergoing an autologous hematopoietic cell transplant. Her stem cells were collected by peripheral blood collection, which were mobilized with cyclophosphamide and filgrastim. During collection she developed a vesicular rash involving her left lower abdominal quadrant, which was documented by PCR analysis to be herpes zoster. This was treated with valacyclovir. Her preparative regimen for transplant was high-dose melphalan, followed by stem cell rescue with her peripheral blood stem cells. Eight days after stem cell infusion, she spiked a fever of 38.6°C (101.5°F). She now also complains of chills and nausea.
