Vertebral Aspergillus osteomyelitis and acute diskitis in patients with chronic obstructive pulmonary disease.
Aspergillus osteomyelitis of the spine with acute diskitis has been well documented in immunocompromised hosts but is rare in immunocompetent patients. Predisposing factors to infection are prolonged neutropenia, hematologic malignancies, chemotherapy, history of prior spinal trauma or surgery, allograft transplantation, or any condition requiring the use of long-term immunosuppressive agents or systemic corticosteroids. Patients with chronic obstructive pulmonary disease (COPD) treated with systemic corticosteroids for either long-term management or frequent exacerbations are at potential risk for such infections. Patients with severe COPD treated primarily with inhaled corticosteroids are considered immunocompetent. This report describes 2 cases of Aspergillus osteomyelitis with acute diskitis in apparently immunocompetent patients with COPD who, aside from brief courses of systemic corticosteroids, were using inhaled corticosteroid therapy. One patient was treated with intravenous amphotericin B alone, whereas the other received amphotericin B and underwent surgical debridement. Both have done well and were symptom free at 6-month follow-up.
