Campylobacter jejuni: enterocolitis and myopericarditis

Area of Science:

• Cardiology
• Infectious Diseases
• Microbiology

Background:

• Campylobacter jejuni enteritis is a common infection globally.
• Cardiac complications from C. jejuni enterocolitis are rare, with few documented cases, predominantly in males and typically benign.
• Severe left ventricular dysfunction is exceptionally rare in C. jejuni myocarditis.

Observation:

• This report details a young male patient diagnosed with Campylobacter myopericarditis.
• This represents the first documented case of Campylobacter-associated myopericarditis in The Netherlands.
• The patient presented with symptoms indicative of cardiac involvement secondary to C. jejuni infection.

Findings:

• The case confirms that Campylobacter jejuni can lead to myopericarditis, affecting cardiac function.
• The underlying mechanism of C. jejuni-induced myopericarditis is not fully understood, with hypotheses including direct bacterial invasion, toxins, immune complexes, or T-cell responses.
• This rare cardiac manifestation underscores the pathogen's potential systemic effects.

Implications:

• As C. jejuni infections rise globally, clinicians must remain vigilant for cardiac complications.
• Early recognition and management of Campylobacter myopericarditis are crucial for patient outcomes.
• Further research into the pathogenesis of C. jejuni-induced cardiac disease is warranted.
