Mucormycosis in the BMT population.
Mucormycosis is known to cause rhinocerebral and pulmonary disease in patients with diabetes, leukemia, and lymphoma. However, the characteristics and outcome of these infections have not been well described in the BMT population. In a 17-year consecutive series of BMT patients, 13 of 1500 patients (0.9%) developed mucormycosis. Ten of the transplants were allogeneic and three autologous. Six infections occurred within 90 days of transplant, and six occurred at or within several days of autopsy. Seven patients were neutropenic and another patient had just engrafted at diagnosis of infection. Sites of infection were lung-brain (n = 4), sinonasal region (n = 3), lung (n = 2), disseminated (n = 2), lung-kidney (n = 1), and bone-muscle (n = 1). All patients were treated with prolonged amphotericin B therapy. Surgical debridement was employed in the three sinonasal infections. Death from mucormycosis occurred in ten of 13 (77%) patients. Two patients are alive, including one who had resolution of sinonasal infection. Mucormycosis may occur in both neutropenic and non-neutropenic patients, and may occur long after hospital discharge for BMT. These infections are often fatal, although patients with limited sinonasal disease may have a better prognosis, especially with early diagnosis and aggressive antifungal therapy.
