Rare nocardiosis in danish patient with diabetes

Abstract

We herein report a rare case that describes and visualizes nocardiosis in a patient with diabetes. The patient presented with recurring fever, gout, leg pain, frailty and muscular pain through nine months, before a core needle biopsi, from an abscess in the abdominal musculature, revealed Nocardia Paucivorans. A PET-CT-scan showed multiple muscular FDG-positive sites. Furthermore, he experienced serious side effects to Sulfametoxazole and Trimethoprim, the antibiotic of choice for this type of infection. He was then switched to Moxifloxacin and Ampicillin. Nocardia often presents as opportunistic infections, typically in patients with severe immunodeficiencies, such as HIV, use of high-dose corticosteroids, hematologic malignancies or immunosuppression following organ transplantation. This case illustrates how a patient with only relative immunodeficiency gets rare nocardiosis. Our sparse knowledge on clinical presentation is based on case-reports and treatment is empirical. Hence, a better understanding of the clinical presentation and treatment is important. Especially given the prospect, that the health care system faces a greater load of patients with diabetes and other immunodeficiencies in the future.
