Diagnosis and treatment of Candida vertebral osteomyelitis: clinical experience with a short course therapy of amphotericin B lipid complex.

BACKGROUND: Musculoskeletal candidiasis occurs in some patients with candidemia resulting from organ infection, IV drug use, or indwelling central venous catheters. Diagnosis is often difficult because of vague symptomatology and a frequent afebrile course. CASE DESCRIPTION: Three patients with Candida vertebral osteomyelitis are presented. All followed the use of indwelling central venous access catheters and antimicrobial therapy between 6 months and 3 years earlier. In 2, fungemia with the same Candida spp. preceded the spondylodiskitis. These 3 patients bring to nearly 75 the number of reported individuals with what was once quite rare. Although IV amphotericin B doxycholate and fluconazole have usually been effective therapy over prolonged periods of time, we used liposomal amphotericin B to treat 2 of our 3 patients. Both received 5 mg/kg daily for 18-42 days that resulted in total disappearance of signs and symptoms.
CONCLUSION: This relatively brief duration of therapy reduces treatment time and is cost-effective.
