<dc:description>OBJECTIVES: Inter-alpha-trypsin inhibitor heavy chain H4 (ITIH4) is associated with various diseases. We evaluated the diagnostic and prognostic significance of serum ITIH4 levels in healthy controls and patients with chronic hepatitis B (CHB), hepatitis B virus (HBV)-related liver cirrhosis, and HBV-related hepatocellular carcinoma (HCC).
DESIGN AND METHODS: The study enrolled 300 individuals (50 healthy controls, 50 with CHB, 100 with HBV-associated cirrhosis, and 100 with HBV-associated HCC). Serum ITIH4 levels were determined by western blot analysis and expressed in densitometry units (DU).
RESULTS: ITIH4 levels were higher in CHB (mean: 252.96 DU) and liver cirrhosis (mean: 206.43 DU) patients than in healthy controls (mean: 75.92 DU) and HCC patients (mean: 92.86 DU) (P &lt;0.001). The area under the receiver operating characteristic curve was 0.71 for the diagnosis of HCC in patients with HBV-related liver disease. Multivariate Cox regression analysis showed that large tumor size (>5 cm) was independently associated with overall survival (hazard ratio 5.894, 95% confidence interval 1.373–25.300, P = 0.017). A Kaplan-Meier survival analysis showed significantly worse survival among HCC patients with both low ITIH4 (&lt;80 DU) and a large tumor size compared to that among other HCC patients (P &lt;0.001), and among patients with high AFP (>200 ng/mL) and low ITIH4 compared to that among other HCC patients (P = 0.041).
CONCLUSIONS: Serum ITIH4 levels are reduced in HCC patients compared to that in CHB and cirrhosis patients, and low serum ITIH4 levels are associated with shorter survival in HBVassociated HCC patients.</dc:description>
<dc:description>목적: Inter-alpha-trypsin inhibitor heavy chain H4 (ITIH4)은 다양한 질환들과 관련이 있다. 본 연구에서는 정상 대조 군과 만성 B 형간염, B 형간염 연관 간 경변 증, B 형간염 연관 간암 환자들에서 ITIH4 의 진단적, 예후예측 인자로서의 중요성을 평가하였다.
방법: 300 명의 환자들을 대상으로 연구를 진행하였다 (50 명의 정상 대조군, 50 명의 만성 B 형간염, 100 명의 B 형간염 연관 간 경변 증, 100 명의 B 형간염 연관 간암). 혈청 ITIH4 값을 Western blot 분석으로 결정하였고, densitometry units(DU) 으로 나타내었다.
결과: ITIH4 는 만성 B 형간염 (평균: 252.96 DU)과 간 경변 증 (평균: 206.43 DU)에서 정상 대조군 (평균: 75.92 DU), 간암 환자군 (평균: 92.86 DU) 보다 더 높게 나타났다 (P&lt;0.001). B 형간염 연관 간 질환 환자에서 간암 진단을 위한 AUROC 값은 0.71 이었다. 다변량 Cox 회귀 분석을 통해 큰 종양 크기 (>5 cm)가 독립적으로 생존율에 연관이 있음을 확인하였다 (위험도 5.894, 95% 신뢰구간 1.373–25.300, P = 0.017). Kaplan-Meier 생존 분석을 진행 하였을 때, 낮은 ITIH4 값 (&lt;80 DU)과 큰 종양크기 (>5 cm)를 모두 충족시키는 환자들이 그렇지 않은 환자들 보다 유의하게 낮은 생존율을 보였다. 그리고, 높은 AFP 값 (>200 ng/mL)과, 낮은 ITIH4 값 (&lt;80 DU)을 모두 충족 시키는 환자들이 그렇지 않은 환자들보다 낮은 생존율을 보였다 (P = 0.041).
결론: 혈청 ITIH4 값은 만성 B 형간염, 간 경변 증 환자들과 비교하여 간암 환자들에서 감소하는 결과를 보였고, 낮은 혈청 ITIH4 값은 B 형 간염 연관 간암 환자들에서 나쁜 생존율과 관련이 있음을 확인 하였다.</dc:description>
