Objective : Surgical site infection (SSI) caused by methicillin-resistant Staphylococcus aureus (MRSA) after spinal instrumentation surgery is often intractable, and removal of the implants is frequently necessary for infection control. Although vancomycin (VCM) has been most frequently used against SSI caused by MRSA, recent literatures questioned its efficacy because of its low tissue penetration. Some experts recommend combination therapy with anti-MRSA agents possessing higher tissue penetration or an anti-biofilm effect. The present report shows outcomes of antibiotic therapy for SSI caused by MRSA after spinal instrumentation surgery.  Materials and methods : From January 2011 to December 2013, four patients developed SSI caused by MRSA after spinal instrumentation surgery. Posterior lumbar interbody fusion was used in all patients. As initial therapy, VCM was given to one patient, and combined teicoplanin (TEIC) and rifampicin (RFP) were administered to the other three. These patients subsequently received therapy with TEIC, linezolid, or daptomycin combined with RFP, sulfamethoxazole-trimethoprim, or clindamycin. These agents were stopped sequentially if C-reactive protein remained negative for more than a week.  Results : Infection was uncontrolled in one patient initially treated with VCM, and removal of the posterior instrumentation and interbody cages was required for infection control. Combined therapy was given postoperatively, with complete cure by 13 weeks after removal of the implants. Infection was controlled and the implants could be retained in the other three patients who were initially treated with TEIC and RFP ; cure was achieved with subsequent combined therapy for 3-15 weeks.  Conclusion : The present study suggests that SSI caused by MRSA is treatable with retention of the implant by using combined therapy with anti-MRSA agents possessing higher tissue penetration than VCM or those with an anti-biofilm effect.

[背景,目的]椎骨脳底動脈閉塞は発症より6時間以上経過して診断されるケースが少なくなく,血栓溶解を施行するかどうか判断が困難な症例が多い.今回椎骨脳底動脈閉塞例に対し血行再建を行った例について,再開通の有無,重症度および治療開始時間が予後に及ぼす影響を検討した. [症例と方法]当院での椎骨脳底動脈閉塞に対する血行再建は発症時間にかかわらず,diffusion MRIで梗塞の面積が20 ml以下または脳幹全体が高信号になっていない例としているが,該当症例は19例あり,12例は発症6時間以内に血行再建が行われ,7例は発症6時間以降に血行再建が行われた.各群について初診時NIHSSと3カ月後のmRS(modified Rankin scale)の関連性を検討した.再開通の評価はTIMI分類で施行した.統計はmRSと年齢,再開通までの時間,NIHSSは分散分析を行い,開通の有無とmRSは分割表分析を行った. [結果]予後は再開通の有無が最も影響し,TIMI分類のGrade 3∼4の11例中9例でmRSが3以下であったが,Grade 0∼1では全例mRSが4以上であった(P<0.01).発症時間,受診時NIHSS,年齢と予後の関係は有意差は認められなかったが,mRS 0∼1の4症例はいずれも発症3時間以内の再開通例であった. [結論]椎骨脳底動脈閉塞は発症時間にかかわらず,diffusion MRIで広範囲に高信号を呈さなければ血栓溶解療法の適応はある.発症時間からの経過にかかわらず再開通後の予後は比較的良好である.神経症状を残さない結果を得るには発症3時間以内の早期再開通が望ましい.
