Case in brief
An immunocompromised patient developed a pacemaker pocket infection caused by Campylobacter jejuni following dual-chamber pacemaker implantation. Despite the absence of systemic symptoms or local inflammatory signs, swelling and fluid accumulation were noted at the device site. Cultures confirmed the infection, leading to a switch from empirical to targeted antibiotic therapy. The device was removed, and after treatment, the patient was discharged without signs of infection.
What made this case unusual
This case highlights Campylobacter jejuni as an atypical pathogen in CIED infections, particularly in the absence of gastrointestinal symptoms, suggesting silent bacteremia.
Diagnostic / clinical pearl
Clinicians should consider CIED infection in immunocompromised patients presenting with subtle pocket changes, even without systemic symptoms.
Why it matters
Recognizing uncommon pathogens like Campylobacter jejuni in CIED infections can improve diagnosis and management, particularly in vulnerable populations.
