Burkholderia cepacia Bacteremia Complicated by Acute Parotid Abscess in a Poorly Controlled Diabetic Patient With Community-Acquired Pneumonia: A Case Report

TL;DR

A diabetic patient with poorly controlled blood sugar developed a rare Burkholderia cepacia infection causing pneumonia and a parotid abscess, which was successfully treated with targeted antibiotics.

Contribution

Highlights an unusual clinical presentation of B. cepacia in a diabetic patient with community-acquired pneumonia.

Findings

B. cepacia bacteremia and parotid abscess occurred in a patient with uncontrolled diabetes and community-acquired pneumonia.

Successful treatment with meropenem and trimethoprim-sulfamethoxazole led to full remission.

The case emphasizes the importance of early diagnosis of rare pathogens in persistent pneumonia.

Abstract

The Burkholderia cepacia complex (Bcc) is a non-fermenting, gram-negative bacillus that is opportunistic and resistant to numerous treatments. It is most typically connected to cystic fibrosis and impaired immune systems. Infection acquired in the community is still rare. Diabetes mellitus is an acknowledged risk factor for severe and uncommon illnesses. We present a 35-year-old patient with poorly controlled diabetes mellitus who developed community-acquired pneumonia, aggravated by Burkholderia cepacia bacteremia and subsequent acute unilateral parotid abscess. Blood cultures identified B. cepacia susceptible to meropenem and trimethoprim-sulfamethoxazole. Targeted antimicrobial therapy led to total clinical and radiological remission. This case illustrates an unexpected manifestation of B. cepacia infection in the context of inadequate glycemic management and underscores the necessity of investigating unique bacteria in persistent community-acquired pneumonia. In addition, this case report raises the concern regarding the potential severity of Burkholderia infections and prompts early diagnosis by physicians to prevent morbidity and mortality.
