A Curious Case of Actinomyces Naeslundii Bacteremia in a Patient with Metastatic Pancreatic Cancer

Abstract

Although considered a saprophyte, Actinomyces naeslundii can cause invasive infection leading to significant morbidity and mortality. Rarely encountered, bacteremia with this agent occurs in the setting of disrupted mucosal barriers. Previous studies suggest that actinomycosis may be a surrogate marker for poor prognosis in immunocompromised hosts. We report herein a case of a patient with metastatic pancreatic cancer who not only had a prompt resolution of Actinomyces bacteremia and a complete response to chemotherapy, but also remained disease free at 12 months after diagnosis. Our case may suggest that concomitant actinomycosis may not necessarily portend a poor prognosis in all immunocompromised patients.

Actinomycosis is a rare, chronic, and slowly progressive granulomatous disease caused by filamentous Gram positive anaerobic bacteria from the Actinomycetaceae family (genus Actinomyces). The disease is characterised by the formation of painful abscesses in the mouth, lungs,breast or gastrointestinal tract. Discover the latest research on actinomycosis here.
