Staphylococcus lugdunensis is a recently described coagulase negative staphylococcal species involved in human infections. Endocarditis caused by Staphylococcus lugdunensis has been reported rarely: fewer than 50 cases have been described so far. The infection is frequently complicated by embolic events and carries a high mortality rate. We report a case of endocarditis due to Staphylococcus lugdunensis in which the native mitral and aortic valves were infected. The bacterium was isolated on cultures from the aortic and mitral vegetations. Appropriate medical and surgical treatment led to a good outcome of the infection. At 6-year follow-up, there was no evidence of recurrence, and the patient showed good functional recovery. He was in New York Heart Association functional class I.
Two successfully treated cases of Staphylococcus lugdunensis endocarditis
2010
Prosthetic valve and pacemaker lead endocarditis by Staphylococcus lugdunensis remain very rare, while the former is associated with an ominous prognosis. Two cases involving a prosthetic aortic valve and a pacemaker lead, respectively, are reported. Despite disease severity and delayed diagnosis, patients recovered fully with combined antimicrobial and surgical treatment.

Staphylococcus lugdunensis is a coagulase-negative staphylococcus (CNS). It is a major cause of prosthetic valve endocarditis; mitral valve prolapse (MVP) has emerged as a prominent predisposing structural cardiac abnormality. We describe a case of Staphylococcus lugdunensis endocarditis in an 18-year-old woman with preexisting mitral valve prolapse complaining of fever, a one-month history of continuous-remittent fever (T(max) 38.6°C). The transthoracic echocardiogram revealed large vegetation on the anterior mitral valve leaflet flopping from the atrial side to the ventricular side. Five sets of blood cultures were positive for coagulase-negative staphylococci. During hospitalization, after two weeks of antibiotic therapy, the patient complained of sudden pain in her right leg associated with numbness. Lower limb arterial Doppler ultrasound showed an arterial thrombosis of right common iliac artery. Transfemoral iliac embolectomy was promptly performed and on septic embolus S. lug...
Endocarditis due to Staphylococcus lugdunensis—a retrospective national registry–based study
European Journal of Clinical Microbiology & Infectious Diseases
We present characteristics of infective endocarditis (IE) caused by Staphylococcus lugdunensis and compare with IE caused by Staphylococcus aureus and other CoNS, in the National Swedish Registry of IE (2008–2018). Thirty episodes of S. lugdunensis IE were registered, of which 21 cases affected native valves, and 7 patients were subjected to surgery. The mortality rate at 30 days was significantly higher for S. lugdunensis IE (20%, n = 6), than for IE caused by other CoNS (7%) or S. aureus (9%) p = 0.016. Septic embolisation was only reported in two cases (7%). The most common treatment was isoxazolyl penicillin (n = 18).

The pitfall of coagulase-negative staphylococci
International Journal of Cardiology, 2009
We report a case of a 60-year-old woman. She was transferred from a local hospital to our cardiovascular medicine department with a diagnosis of infectious endocarditis due to Staphylococcus lugdunensis. Transthoracic echocardiograph confirmed the presence of large vegetations on the native aortic and mitral valve, and subsequent severe regurgitation due to the aortic and mitral valve destruction. Emergent operation was performed and patient's life was barely rescued. However, S. lugdunensis belongs to coagulase-negative staphylococci, which are generally regarded as relatively avirulent bacterium, the endocarditis caused by S. lugdunensis can be invasive and often resembles endocarditis due to Staphylococcus aureus. Therefore, whenever this organism is found in patients with endocarditis, early surgical treatment of the infected valve should be considered.

Native valve endocarditis caused by coagulase negative staphylococci has become more comiton. A study of 35 cases showed that the infections were usually acquired in the community and occurred in men (mean age 51 years). A pre-existing cardiac abnormality (mitral leaflet prolapse in a third of patients) was detected in 26 (74%). The source of the organisms in the community acquired infections was assumed to be the skin, though lesions were seldom demonstrated; most hospital acquired infections resulted from intravenous devices. Community acquired organisms were usually sensitive to penicillin, whereas those acquired in hospital were often multiresistant. Most infections were caused by Staphylococcus epidermidis. The frequency of acute presentation (26%) and of major neurological abnormality (23%), together with the need for valve replacement (often emergency) (51%) and the mortality (36%) suggest that coagulase negative staphylococci can be virulent aggressive pathogens, mimicking Staphylococcus aureus.

Infective Endocarditis (IE) is a very rare complication following spinal epidural injection and requires high index of suspicion for early diagnosis and effective management. Staphylococcus Lugdunesis is a coagulase negative staphylococcus (CoNS) that, unlike other CoNS, may result in aggressive form of native valve infective endocarditis (IE) mimicking IE caused by S aureus. Surgical intervention is usually needed to control infection in most cases of S. Lugdunesis IE. Herein, we report a case of young lady with congenital Gerbode defect who developed tricuspid native valve IE with S. Lugdunesis secondary to spondylodiscitis post lumbar epidural injection that was performed for disk prolapse. She required urgent surgical intervention and had an excellent outcome.

Coagulase-negative staphylococci are the most frequently isolated microorganisms in early prosthetic valve endocarditis. However, they rarely cause endocarditis in native valves. The profile of patients with left-sided native valve endocarditis by coagulase-negative staphylococci is unknown, because available data are scarce and outdated. We analyzed the epidemiological, clinical, radiographic, microbiological, and echocardiographic features and clinical course in 17 patients with this entity out of a total of 441 consecutive patients diagnosed as having endocarditis. The results show that left-sided native valve endocarditis caused by coagulase-negative staphylococci is more common than previously reported, can cause heart failure due to valvular involvement, often needs surgery, and is associated with high mortality.
