Abstract:
Objective To explore the effectiveness and safety of Linezolid (LIZ) in treating children with infective endocarditis (IE).Methods The clinical data of 112 children with IE and treated in the Shanghai Children's Medical Center of Shanghai Jiao Tong University School of Medicine from August 2008 to September 2015 were retrospectively analyzed.There were 64 boys and 48 girls,and the age of IE onset ranged from 1 month to 17 years [(6.0 ± 4.8) years].Twenty-nine patients received LIZ treatment ＞ 7 days (LIZ treatment group),including 21 males and 8 females,and the age ranged from 5 months to 15 years [(6.9 ±5.2) years].The remaining 83 patients were identified without LIZ treatment(non-LIZ treatment group),including 43 boys and 40 girls,and the age ranged from 1 month to 17 years [(5.7 ±4.7) years].The etiological results,curative effect and adverse reactions of the LIZ treatment group were observed.Results Among the LIZ treatment group,22 cases had congenital heart disease and 1 case had intravenous catheter.There were 10 cases with infection of staphylococcus aureus,6 cases with coagulase negative staphylococcus,5 cases with oral streptococci and Streptococcus bovis group,3 cases with streptococcus pneumonia,2 cases with enterococcus faecium and 3 cases with negative blood culture results.All cases of the LIZ treatment group received Vancomycin therapy at first,LIZ was given when the Vancomycin therapy failed(16 cases with temperature reiteration,1 case inadequate microbiological response),Vancomycin intolerance (6 neutropenia,2 renal toxicity,2 allergy),and oral maintenance therapy (2 cases).The duration of LIZ treatment ranged from 9 to 135 days [(39.2 ±27.2) days].Three patients (10.3％) had adverse effects during LIZ treatment,1 case with severe digestive symptoms after treatment,1 case with teeth discoloration,1 case with the indicators decreasing by 2 routine blood test.Meanwhile,16 cases of 85 patients (18.8％) had side effects during Vancomycin treatment,in which 7 cases with neutropenia,6 cases with rash and 3 cases with renal insufficiency.But there were no significant differences in adverse effects between LIZ and Vancomycin treatment (x2 =1.l19,P ＞0.05).Twenty-five cases were cured (86.2％) and 2 cases dead (6.9％) in the LIZ treatment group.And no significant difference was found in cure rate,or mortality between LIZ treatment group and non-LIZ treatment group (86.2％ vs.77.1％,x2 =1.090;6.9％ vs.8.4％,x2 =0.069,all P ＞ 0.05) at 6 to 84 (23.9 ± 19.1) months follow-ups.Conclusions LIZ can be used to deal with Vancomycin failure and IE caused by gram positive coccus.LIZ was generally well tolerated in patients with IE.It may be useful in cases of IE complicated by brain abscesses for the good distribution.It is 100％ orally bioavailable,allowing oral administration for outpatients.
