Our goal was to estimate the local prevalence of Streptococcus pneumoniae nonsusceptible to penicillin and amoxicillin after widespread use of the heptavalent pneumococcal vaccine and to revise community-specific recommendations for first-line antibiotic treatment of acute otitis media.<\/jats:p>\n               <jats:p>METHODS. We conducted serial prevalence surveys between 2000 and 2004 in the offices of community pediatricians in St Louis, Missouri. Study participants were children &amp;lt;7 years of age with acute upper respiratory infections. Children treated with an antibiotic in the past 4 weeks were excluded. S pneumoniae was isolated from nasopharyngeal swabs using standard techniques. Isolates with a penicillin minimum inhibitory concentration &amp;gt;2 \u03bcg\/mL were considered to be S pneumoniae nonsusceptible to amoxicillin.<\/jats:p>\n               <jats:p>RESULTS. There were 327 patients enrolled in the study. Between 2000 and 2004, vaccine coverage with \u22653 doses of heptavalent pneumococcal vaccine increased from 0% to 54%, but nasopharyngeal carriage of S pneumoniae was stable at 39%. The prevalence of S pneumoniae nonsusceptible to penicillin fell from 25% to 12% among patients, did not vary if &amp;lt;2 years of age, was reduced in children with \u22653 doses of heptavalent pneumococcal vaccine, and increased in child care attendees but reduced in attendees who had \u22653 doses of heptavalent pneumococcal vaccine. The prevalence of S pneumoniae nonsusceptible to amoxicillin in patients remained &amp;lt;5%.<\/jats:p>\n               <jats:p>CONCLUSIONS. In our community, widespread use of heptavalent pneumococcal vaccine has reduced the prevalence of S pneumoniae nonsusceptible to penicillin, and the prevalence of S pneumoniae nonsusceptible to amoxicillin remains low (&amp;lt;5%). If antibiotic treatment is elected for children with uncomplicated acute otitis media, we recommend treatment with standard-dose amoxicillin (40\u201345 mg\/kg per day) for children with \u22653 doses of heptavalent pneumococcal vaccine, regardless of age and child care status. High-dose amoxicillin should be used for children with &amp;lt;3 doses of heptavalent pneumococcal vaccine and those treated recently with an antibiotic.<\/jats:p>","DOI":"10.1542\/peds.2005-2651","type":"journal-article","created":{"date-parts":[[2006,6,1]],"date-time":"2006-06-01T23:20:51Z","timestamp":1149204051000},"page":"e1087-e1094","source":"Crossref","is-referenced-by-count":17,"title":["Empiric First-line Antibiotic Treatment of Acute Otitis in the Era of the Heptavalent Pneumococcal Conjugate Vaccine"],"prefix":"10.1542","volume":"117","author":[{"given":"Jane","family":"Garbutt","sequence":"first","affiliation":[{"name":"Division of General Medical Sciences"},{"name":"Department of Pediatrics, Washington University School of Medicine, St Louis, Missouri"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Isabel","family":"Rosenbloom","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Washington University School of Medicine, St Louis, Missouri"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jenny","family":"Wu","sequence":"additional","affiliation":[{"name":"Division of General Medical Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gregory A.","family":"Storch","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Washington University School of Medicine, St Louis, Missouri"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"417","published-online":{"date-parts":[[2006,6,1]]},"reference":[{"key":"2021120823023457100_R1","doi-asserted-by":"crossref","unstructured":"McCaig LF, Besser RE, Hughes JM.
