거대세포바이러스는 헤르페스바이러스의 한 종으로 전 세계적으로 광범위하게 분포되어 있는 바이러스이며 밀접한 신체 접촉 환경에서 잘 전파되기 때문에 공동생활과 위생상태 조건이 열악한 저개발국가에서 감염 빈도가 높다. 감염 후 대부분의 경우 무증상 잠복 상태로 지내게 되나 면역저하 환자에서는 심각한 질병의 발생 및 높은 사망률을 가진다. 면역능이 정상인 경우에는 대개 무증상이지만, 10% 이내에서는 불쾌감, 지속되는 발열, 경도의 간기능 이상, 림프구증가증 등이 보일 수 있다. 이런 증상은 일반적으로 미약하거나 자연 치료되는 것이 보통 이고, 증상이 중하거나 다장기 손상이 나타나는 등의 심한 경우는 매우 드문 것으로 알려져 있다. 면역능이 정상인 환자에서는 임상적으로 중요한 감염증을 일으키는 경우가 매우 드물고, 증상도 비특이적이기 때문에 질환의 초기에 거대세포바이러스 감염증을 의심하는 것은 어렵 다. 저자들은 정상면역 환자에서 거대세포바이러스 간염 1예를 경험하였기에 보고하는 바이다. 증례: 남자 27세 특이 병력 없던 분으로 내원 3주 전부터 fever 있어 L/C 병원 방문 시행한 검사상 AST/ALT 상승된 소견 및 37.8의 fever 있어 acetaminophen 처방 받아 복용하였다. 3주간 mild fever 지속 및 피로감 있어 L/C 병원 재방문 시행한 검사상 AST/ALT 호전 없어 F/E 위해 본원 전원되었다. 당뇨병이나 고혈압, 결핵 등의 특이 병력 없었으며 흡연은 하지 않았고, 술은 거의 마시지 않았다. 혈액 검사에서 혈색소 15.4 g/dL, 혈소판 149000/mm3, 백혈구 10,820/mm3, 간기능 검사에서 AST/ALT 91/120 IU/L, ALP/rGTP 199/42 IU/L, albumin 3.8 g/dL, Total bilirubin 0.6 mg/dL, PT/aPTT 11.8/36.3 sec였다. 류마티스 질환과 연관된 ANA/AMA는 음성이였다. 혈청학 검사에서 hepatitis A, B, C, HIV, VDRL, EBV, HSV 모두 음성이나 CMV IgM/IgG 양성이였고 CMV Real Time PCR 정량 검사상 1,932 copies/mL이였다. Ceruloplasmin 32 mg/dL로 정상이였고 Kayser- Fleischer (KF) ring은 보이지 않았다. 간 전산화 단층촬영에서 비장비대가 있고 초음파 유도하 간 조직 검사상 mild portal inflammation, moderate lobular inflammation, minimal portal fibrosis, mild cholestasis 있었고 viral inclusion은 보이지 않았다. 우리는 CMV Real Time PCR 정량 검사를 통해 거대세포바이러스 간염을 진단할 수 있었고 대증적 치료만으로 증상호전 보여 퇴원하였다. 퇴원 후 8주째 시행한 CMV Real Time PCR 정량 검사에서 316 copies/mL 이하, 24주째 시행한 CMV IgM 음전 및 간기능검사 정상화 되었다.

Background: Despite the regular surveillance for hepatocellular carcinoma (HCC), we can often meet the patients who are initially diagnosed as having advanced staged HCC. Therefore, we aimed to investigate the frequency of the patients who were initially expressed as advanced HCC during surveillance at-risk population, and intended to evaluate the clinical characteristics of these patients. Methods: A total of 120 patients who were initially diagnosed as HCC during surveillance at our institution between January 1999 and January 2013 were consecutively enrolled. HCC surveillance was done with regular follow-up of abdominal ultrasonograpy and serum alpha-fetoprotein at-risk population. HCC was diagnosed based on the criteria of the American Association for the Study for Liver Diseases. Barcelona Clinical Liver Cancer (BCLC) staging system was used for tumor stage. Results: Of the 120 patients, 15 (12.5%) patients were diagnosed as having initially BCLC stage C. Of these 15 patients, the median age was 55 years (range, 37-79 years), and 15 (88.2%) were male. All of them had clinically liver cirrhosis. Fourteen (93.3%) patients had nodular tumor type with the median tumor size of 3.1 cm (range, 1.5-6.7cm). Only one patient had infiltrative tumor type. Lymph node metastasis was observed in 8 (53.3%) patients, and portal vein tumor thrombosis was observed in 7 (46.7%) patients (Table I-IV). Conclusions:

Our data showed that 12.5% of HCC patients may express as having initially advanced HCC at-risk population, especially with liver cirrhosis despite the regular surveillance. Moreover, portal vein tumor thrombosis or lymph node metastasis may not be detected early with ultrasonography. During surveillance, enhanced dynamic images may need to be performed to detect portal vein tumor thrombosis or lymph node metastasis.However, large scaled prospective study needs to be performed to confirm our data.
