Objective:

To report a case of gonococcal infective endocarditis diagnosed through molecular testing despite negative blood cultures, highlighting its clinical significance.

Key Findings:
  • Gonococcal infective endocarditis is rare but aggressive, often leading to severe complications, with up to 72% requiring surgical intervention.
  • Standard blood cultures frequently yield negative results for Neisseria gonorrhoeae due to growth requirements and culture inhibitors.
Interpretation:

A thorough sexual history and the use of PCR can aid in the timely diagnosis of atypical infectious causes of endocarditis, emphasizing the need for awareness in clinical practice.

Limitations:
  • Case report limited to a single patient, which may not represent broader population trends, and potential underreporting in similar cases.
  • Potential biases in reporting and diagnosis due to the unique clinical presentation.
Conclusion:

This case underscores the need for awareness of gonococcal endocarditis in patients with culture-negative infective endocarditis, especially with embolic phenomena, and the importance of PCR testing.
