Here, we report the case of a 59-year-old male patient who presented with acute hepatitis. fter being admitted for fever and right upper quadrant pain for a 3-day period, military tuberculosis was diagnosed and treated with antituberculosis medication. Despite treatment, which was based on laboratory results and radiologic findings suggestive of acute hepatitis, fever persisted, jaundice developed, and hepatic enzyme levels increased. Percutaneous liver biopsy was performed to assist in the differential diagnosis of acute hepatitis and findings from the biopsy specimen revealed typical hepatic tuberculosis. ntituberculosis treatment was initiated, and the fever gradually subsided and hepatic enzyme levels decreased. (Korean J Med 76:627-631, 2009) Key Words: Tuberculosis; Hepatitis 서론급성간염의원인으로바이러스간염과알코올간염이대부분을차지한다 1). 그외급성간염의원인으로는자가면역간염, 간독성약물에의한간염, 사르코이드증 (sarcoidosis) 이나결핵에의한육아종간염 (granulomatous hepatitis) 등이있다 1). 파종결핵에서간침범은매우흔하게나타나는임상양 상이나, 황달과간기능저하등급성간염의형태로나타나는경우는드문것으로알려져있다 2-4). 또한진단을위해간조직검사와같은침습적인검사를필요로하기때문에초기에간과되기쉽고조기진단및그치료에있어서어려움이있다 5). 저자들은급성간염으로내원한환자에서파종결핵을진단하고결핵치료를통해간염을치료한 1예를경험하였기에보고한다.

() Histopathological analysis of a liver biopsy revealed chronic granulomatous inflammation with caseous necrosis (H&E, 400).

Cruise 는 1,748 명의결핵환자에서단지 7명에서만간효소의상승과황달을보고하였으며 3) Essop 등도 8,342명의결핵환자에서 96명에서만결핵성간염을보였다고하였다 5). Curry는이전문헌고찰을통해황달을동반한결핵성간염을 30명정도만보고하였다 10). 이처럼파종결핵에서급성간염은그빈도가매우드물고또한진단을위해간조직검사와같은침습적인검사를시행해야하기때문에조기진단과치료가어렵다 5). 결핵성간염환자에서간부전으로의이행은드물지만, 발생할경우나쁜예후를보이고있다 11). 결핵성간염의증상은상복부통증이흔하며발열, 체중감소가흔하게나타난다. 특히파종결핵이동반되었을경우에는기침, 객혈, 호흡곤란등의호흡기증상이나타날수있다. 이학적검사에서는간비대가가장흔하며상복부압통, 비장비대, 황달, 빈혈등이흔하다 5). 검사실소견으로는저나트륨혈증이흔히나타나며 LT, gamma GT의상승이흔히나타난다. 또한범혈구감소증이흔히나타나며이경우거대비장에의한경우가대부분이지만파종결핵이동반된환자에서는결핵균의골수침범에의해서도범혈구감소증이생길수있다 5). 결핵성간염은초음파에서는간음영이증가되어보이며복부전산화단층촬영에서는보통간비대소견외에는다른특징적인소견은없다. 이렇듯결핵성간염에서증상이나이학적검사, 검사소견그리고방사선검사의결과는비특이적이어서결핵성간염을진단할수는없으며간조직생검이결핵성간염을진단하는데중요한검사방법이다. 병리조직학적으로는간실질내에서육아종형성이가장흔한소견이지만, 담도계나간문의림프절에결핵육아종을형성하여담도폐색을유발하기도한다 13). 본증례에서는급성간염의원인으로고혈압이나통풍약제에의한간염을우선생각해볼수있었지만환자는고혈압약제를 10년, 통풍약제를 1년이상복용중이었으며약제를중단한이후에도간수치의지속적인상승이있었고, 발열이지속되어간독성약제에의한간염은아닌것으로생각되었다. 그리고간염바이러스검사상음성이었으며음주흡연력이없어급성간염의흔한원인인바이러스간염과알코올간염또한가능성이떨어져보였다. 그래서급성간염의드문원인인자가면역간염, 사르코이드증, 결핵에의한육아종간염그리고임파종에의한간염등을감별하기위해간조직생검을시행하였으며간조직생검에서간실질내건락육 - 630 -
- 최희경외 6 인. 급성간염으로진단된결핵성간염 - 아종형성및항산균이보여결핵성간염을진단하였다. 파종성결핵에서골수침범은 25~75% 정도되며골수검사에서재생불량빈혈, 과립백혈구감소증, 백혈병모양반응, 범혈구감소증등의소견이보일수있다 5). 간결핵의치료에대한대조임상시험의자료가제한되어있지만, 흔히 6개월표준처방이추천되고있다 12). Isoniazid, rifampin, ethambutol 그리고 pyrazinamide를첫 2개월사용하고, 이후 4개월간 isoniazid, rifampin, ethambutol을사용한다. 하지만항결핵제제자체도간독성이있어결핵성간염을치료하는과정에서간수치상승의원인이되기도한다. 스테로이드의보조적치료는추천되지않고있다 12). 결핵성간염의경우때로는적절한치료를하더라도간부전으로이행할수있으며치료가지연시에사망에이르기도한다 5). 본증례는비장침범과범혈구감소증등파종결핵을시사하는소견이동반되어있었으나발열과간종대, 간수치상승및황달등급성간염의증상이주로나타나초기에는파종결핵을의심하기어려웠으며생검에서파종결핵을진단한경우로, 이처럼급성간염으로내원한환자에서임상적판단을통해결핵을초기에의심하여조기에간조직검사를시행하여진단하고치료하는것이매우중요하다고하겠다. 요약파종결핵에서급성간염은그빈도가매우드물고간조직생검을필요로하기때문에초기에간과되기쉽다. 저자들은급성간염으로내원한환자에서파종결핵을진단하고결핵치료를통해간염을치료한 1예를경험하였기에보고한다. 중심단어 : 결핵 ; 간염 REFERENCES 1) Friedman LS, Martin P, Santiago JM.
