Abstract:
Objective:To explore the clinical characteristics and appropriate treatment of occult pneumococcal bacteremia (OPB) in children.Methods:The clinical characteristics, drug sensitivity and antibiotic use of 39 children with OPB who met the inclusion criteria in the Pediatric Internal Medicine Ward of Shenzhen Children′s Hospital from January 2013 to December 2018 were retrospectively analyzed.Results:The median age of onset in OPB in children was 2 years and 4 months, and 74.4% of children(29/39 cases) were between 6 months and 3 years.The average total fever duration was 3.69 days (1-14 days), and the average hospital stay was 6.74 days.Peripheral blood white blood cell count was >15×10 9/L in 89.7% (35/39 cases) of the children, C-reactive protein was increased in 76.9% (30/39 cases) of the children, and procalcitonin > 2 mg/L in 38.9% (14/36 cases) of the children.During hospita-lization, all the children received the treatment of intravenous antibiotics.The antibiotics used initially included Cefuroxime in 11 cases (28.2%), Amoxicillin sulbactam sodium in 10 cases (25.6%), Ceftriaxone sodium in 7 cases (17.9%) and Meloxicillin sulbactam in 6 cases (15.4%). The average fever clearance time after the antibiotic therapy was 1.4 days, and the average intravenous antibiotics treatment time was 6.2 days.The results indicated that the insensitivity rate of Penicillin was 46.2%, the insensitivity rate of Amoxicillin, Ceftriaxone and Cefotaxime were 22.2%, 10.3% and 17.9%, respectively, Erythromycin resistant rate was 100.0%, and no patient was resistant to Vancomycin and Linezolid. Conclusions:OPB occurs most frequently in infants aged from 6 months to 3 years old, with low drug resistance to Amoxicillin, Ceftriaxone and Cefotaxime.Children with complete immunity have shorter fever duration and good prognosis after antibiotic treatment.
