[Endocarditis caused by Staphylococcus lugdunensis. Hospital incidence].

BACKGROUND: Staphylococcus lugdenensis is a coagulase negative staphylococcus (CNS) associated with a wide spectrum of infections among which infectious endocarditis may be found and in which it is an aggressive pathogen. METHODS: Since 1993 a systematic search for S. lugdenensis in all the staphylococci isolated in blood cultures and the possibility of endocarditis en all of these was determined. A review of all the cases of endocarditis in the literature was performed. RESULTS: Three cases of endocarditis by S. lugdenensis on the native valve were detected from January 1993 to June 1997. None of the patients presented previous heart disease or risk factors. In all the cases, at least three blood cultures were positive for S. lugdenensis and vegetations were observed by echocardiogram. Despite correct antibiotic treatment, disappearance of fever, negativization of control blood cultures and in the third case, valve replacement, two patients presented heart failure and all died. On review of the literature 31 cases of endocarditis were found with valve replacement and mortality being 55%. It should be indicated that 85% of the patients who survived required surgery. CONCLUSIONS: Endocarditis by S. lugdenensis is a severe infection frequently requiring valve replacement and is associated with a high mortality. Therefore, adequate early identification of the microorganism is necessary distinguishing it from the remaining CNS.

[Infected atrial myxoma simulating infective endocarditis].

BACKGROUND: We present a case of infected atrial myxoma simulating bacterial endocarditis. MATERIAL AND METHODS: A 75 year old male, without any antecedents of interest, with fever an evolution a month, and a cardiac murmur. Blood cultures were practiced by BACTEC N.R. 730 system. The diagnosis was performed by the bidimensional and transesophageal echo, and confirmed with the resection from surgery. The method of bibliographical review used, has been the data base of comprehensive Medline, cvc since 1987 up June 1992 and the Oncodise's Concerlit archive from the year 1985 up to june 1992 the date base of the IME (Indice Médico Español) was also review up to April 1992. RESULTS: The blood cultures were positive, 7/7 Streptococcus viridans and 3/7 a Staphylococcus epidermidis resistant to meticiline, we them with the same antibiogram. Echocardiography and angiography show a lef atrial mass, surgical resection of the mass, confirmed the hystological diagnostic of the myxoma and signs of infection. CONCLUSIONS: This is the first case in our country, with shows the rarity of it. We analyze the differential diagnosis with the non infected myxoma and the bacterial endocarditis. We think that there should be an early surgical treatment, together with antibiotic therapy, due to the high incidence of embolism in theses patients.
