Leuconostoc bacteremia in a patient with amyloidosis secondary to rheumatoid arthritis and tuberculosis arthritis

Abstract

Leuconostoc infections are rare and usually occur in immunocompromised patients. This report describes a case of Leuconostoc lactis bacteremia in a patient with coexisting rheumatoid arthritis and tuberculosis arthritis. A disrupted gastrointestinal barrier due to gastrointestinal amyloidosis in long-standing rheumatoid arthritis and tuberculosis arthritis could be a risk factor for Leuconostoc bacteremia. Despite aggressive antibiotic treatment, the patient progressed to septic shock and multi-organ failure. The fatal course might have been caused by rapid progression of gastrointestinal pathology, which could be a risk factor for Leuconostoc bacteremia.
