Septic arthritis caused by K. pneumoniae is a quite rare and has not been reported in Korea. Therefore, the authors report a case of the septic arthritis in the knee joint caused by K. pneumoniae in a patient with type 2 diabetes mellitus and osteoarthritis of the knee that successfully treated by early detection and arthroscopic synovectomy.

69 Septic Knee Arthritis Caused by Klebsiella pneumoniae 다 (Fig. 2). MRI상 T1 조영증강에서는저음영, T2 조영증강에서는고음영으로보이는대퇴하부의골수염의심소견이관찰되었으나이는본원영상의학과전문의의판독에의해감염에의한침윤보다는반응성의골수변화로확인되었다. 이에골수염은배제하고퇴행성골관절염에동반된화농성슬관절염으로진단하여내원당일관절경을이용한좌측슬관절탐색술을시행하였고 Gachter state III의염증소견이관찰되었다 (Fig. 3). 관절내세척술, 변연절제술및활액막제거술을시행하였고수술후슬관절내의다른합병증은확인되지않았다. 관절세침흡입및술중관절액의균배양검사와혈액배양검사상모두 K. pneumoniae 가동정되었고내원당시에는 vancomycin (1 g/twice a day [bid]/d) 과 3세대 cephalosporin (2 g/bid/d, ceftriaxone sodium) 을경험적으로함께사용하였으나항생제감수성검사상 3세대 cephalosporin 에감수성을보여이를계속정주하였다. K. pneumoniae의감염병소를찾기위해흉부및복부 CT와함께안구내염확인을위한전안부및안저검사시행하였으나감염소견이확인되지않았다. 술후 5주째환자증세매우호전된양상관찰되었고혈액검사상백혈구수 6,210/mm 3 ( 다핵형백혈구 69.4%), ESR 66 mm/h, CRP 3.24 mg/dl로확인되어본원감염내과전문의와상의후경구항생제인 cefixime 100 mg/bid/d로전환하여퇴원하였다. 이후술후 6주째외래추시상감염의재발소견은확인되지않았으며혈액검사상백혈구수 4,950/mm 3 ( 다핵형백혈구 67.1%), ESR 55 mm/h, CRP 1.11 mg/dl로측정되었다. 술후 10개월외래추시상슬관절운동범위 5-115 로확인되었고감염의재발소견은확인되지않았으며혈액검사상백혈구수 8,510/mm 3 ( 다핵형백혈구 77.%), ESR 23 mm/h, CRP 0.46 mg/dl로측정되었다. 고찰 K. pneumoniae에의한화농성슬관절염은매우드문질환이다. 보고된문헌또한드물어 Lin 등 5) 은 2009년까지영어로작성된의학논문중당뇨를앓고있는환자중반복적인 K. pneumoniae 감염에의한화농성관절염이 19예확인되었다고보고하였다. Silke 등 4) 은 K. pneumoniae에의한화농성슬관절관절염을감수성맞는항생제사용과함께관절경적세척술및변연절제술로치료한 2예를보고하였으나그두명이신장이식을받은면역억제된환자여서본증례와는차이가있다. 본증례의경우당뇨병을장기간앓았으나혈당강하제사용으로혈당수치는잘조절되고있던 70세남자환자에서원발병소없이 K. pneumoniae에의한세균성화농성관절염이발생하였다. 성인에서세균성화농성관절염의가장흔한원인균은 Staphylococcus aureus이며호발빈도는기저질환에따른개인간의차이는있으나 37%-67% 정도로알려져있다. 6) 이와는대조적으로그람음성균에의한세균성화농성관절염은 9%-20% 호발하며 Escherichia coli가가장흔한원인균으로알려져있다. 7) 신생아나고령의환자, 당뇨등의만성질환을앓아온환자등면역력이낮은환자는그람음성균에의한세균성화농성관절염발생가능성이높다. K. pneumoniae는이중화농성관절염을발생하는비율이매우낮으며, 간농양, 폐렴, 요로감염등의 1차감염후혈행성전파를통한 2차감염으로화농성관절염을일으키는것으로알려져있다. 3) 본증례에서확인된 K. pneumoniae에의한화농성관절염은혈행성전파에의한것으로생각되며화농성슬관절염의심시조기에관절세침흡입검사및배양검사를시행하여감수성에맞는항생제를사용하는것이치료에도움이되는것으로생각한다. 화농성슬관절염치료의기본원칙은관절내농양의배농과세척과함께감수성에맞는항생제를사용하는것이다. 관절내농양의배농과세척을하는데있어관절경적세척술및변연절제술을일차적으로시행할수있으나논문에따라재발하는빈도를 6%-42% 정도로보고하고있다. 8,9) 일부저자들은관절절개술및관절성형술을통한침습적인치료로재발을막을수있다고보고하고있으나 10) 본증례에서는관절경적세척술, 변연절제술및활액막제거술로좋은결과를얻을수있었다. 관절세침흡입검사로시행한관절액배양검사및혈액배양검사에서모두 ceftriaxone sodium에감수성을가진 K. pneumoniae가동정되었으며감수성결과에맞게항생제치료를시행하였다. 고령및장기간당뇨병을앓아면역력이저하된환자에서본증례처럼특이한균주에의해서도화농성슬관절염이발생할수있기때문에화농성슬관절염의심환자진료시환자의과거력을정확하게확인하고이에따른조기치료및정확한균동정에따른감수성있는항생제의사용이중요할것으로생각한다.
