Gonococcal endocarditis in a 32-year-old male: a rare presentation of an underrecognized disease – case report

Abstract

Introduction and importance: Disseminated gonococcal infection (DGI) is an infrequent but serious complication of gonorrhea that can exhibit atypical symptoms. While rare, it can lead to infective endocarditis (IE), a condition that affects the heart valves and can result in severe and potentially life-threatening outcomes. Case presentation: We present a case of Neisseria gonorrhoeae-caused IE confirmed by blood culture and direct isolation from the aortic valve vegetation. Our patient experienced complications, including glomerulonephritis, respiratory failure, and positive troponin. Urgent surgery successfully removed a large vegetation, replaced the aortic valve, and improved cardiac function. Follow-up showed symptom resolution. Clinical discussion: DGI can present atypically with a triad of tenosynovitis, polyarthralgia, and rash, even without genitourinary symptoms. However, it can also present with nonspecific symptoms, leading to a later diagnosis of IE, as observed in our patient, who developed an aortic valve abscess and aortic regurgitation. Conclusion: This case provides important insights into the diagnosis and management of gonococcal endocarditis, emphasizing the significance of early recognition, timely intervention, and multidisciplinary collaboration in improving patient outcomes. It is imperative to have a high level of suspicion for this rare entity, given its high virulence and potential for severe complications.
