    ABSTRACT: We performed a clinical study of pneumococcal endocarditis (PE) in adults at 15 major Spanish hospitals during a 21-year period (1978-1998). During this time, 63 patients had PE due to Streptococcus pneumoniae diagnosed. Of the 63 isolates recovered from these patients, 24 (38%) and 6 (10%) showed resistance to penicillin (minimum inhibitory concentration [MIC], 0.1-4 microg/mL) and cefotaxime (MIC, 1 microg/mL), respectively. Twenty-two (35%) of the patients died. Left-side heart failure, but not penicillin resistance, was independently associated with a higher risk of death (odds ratio, 1.33; 95% confidence interval, 1.04-1.71; P=.026). Patients without meningitis who had PE due to penicillin-resistant S. pneumoniae could be treated with high-dose penicillin or a third-generation cephalosporin if the MIC for penicillin was < or =1 microg/mL. For patients with concurrent meningitis, high doses of cefotaxime could be used if the MIC for cefotaxime was < or =1 microg/mL. Early recognition of heart failure and surgery may help to decrease mortality.

    ABSTRACT: We describe 30 cases (1.7%) of community-acquired penicillin-susceptible Streptococcus agalactiae endocarditis among 1771 episodes of endocarditis diagnosed in 4 Spanish hospitals from 1975 through 1998. Endocarditis affected a native valve (most often the mitral valve) in 25 cases (83%). Surgical valve replacement was performed for 12 patients (40%). Fourteen patients (47%) died. Mortality rates for patients with native and prosthetic valve endocarditis were 36% and 100%, respectively (P=.01). The mortality rate for native valve endocarditis decreased during the last 6 years of the study (from 61% in 1975-1992 to 8% in 1993-1998; P<.05). Additionally, 115 cases in the literature from 1962-1998 were reviewed. During 1980-1998, the percentage of patients who underwent cardiac surgery increased from 24% (in the previous period, 1962-1979) to 43% (P=.05) and the mortality rate decreased from 45% to 34% (P=NS). S. agalactiae is an uncommon cause of endocarditis with a high mortality rate, although the prognosis of native valve endocarditis has improved in recent years, probably because of an increased use of cardiac surgery.
