AIM:To elucidate the correlation between hepatic blood flow and liver function in alcoholic liver cirrhosis(AL-LC).METHODS:The subjects included 35 patients with ALLC(34 men,1 woman;mean age,58.9±10.7 years;median age,61 years;range:37-76 years).All patientswere enrolled in this study after obtaining written informed consent.Liver function was measured with tests measuring albumin(Alb),prothrombin time(PT),brain natriuretic peptide(BNP),branched amino acid and tyrosine ratio(BTR),branched chain amino acid(BCAA),tyrosine,ammonia(NH3),cholinesterase(Ch E),immunoreactive insulin(IRI),total bile acid(TBA),and the retention rate of indocyanine green 15 min after administration(ICG R15).Hepatic blood flow,hepatic arterial tissue blood flow(HATBF),portal venous tissue blood flow(PVTBF),and total hepatic tissue blood flow(THTBF)were simultaneously calculated using xenon computed tomography.RESULTS:PVTBF,HATBF and THTBF were 30.2±10.4,20.0±10.7,and 50.3±14.9 m L/100 m L/min,respectively.Alb,PT,BNP,BTR,BCAA,tyrosine,NH3,Ch E,IRI,TBA,and ICG R15 were 3.50±0.50 g/d L,72.0%±11.5%,63.2±56.7 pg/m L,4.06±1.24,437.5±89.4μmol/L,117.7±32.8μmol/L,59.4±22.7μg/d L,161.0±70.8 IU/L,12.8±5.0μg/d L,68.0±51.8μmol/L,and 28.6%±13.5%,respectively.PVTBF showed a significant negative correlation with ICG R15(r=-0.468,P<0.01).No significant correlation was seen between ICG 15R,HATBF and THTBF.There was a significant correlation between PVTBF and Alb(r=0.2499,P<0.05),and NH3 tended to have an inverse correlation with PVTBF(r=-0.2428,P=0.0894).There were also many significant correlations between ICG R15 and liver function parameters,including Alb,NH3,PT,BNP,TBA,BCAA,and tyrosine(r=-0.2156,P<0.05;r=0.4318,P<0.01;r=0.4140,P<0.01;r=0.3610,P<0.05;r=0.5085,P<0.001;r=0.4496,P<0.01;and r=0.4740,P<0.05,respectively).CONCLUSION:Our investigation showed that there is a close correlation between liver function and hepatic blood flow.
AIM: To elucidate the correlation between hepatic blood flow and liver function in alcoholic liver cirrhosis (AL-LC). METHODS: The subjects included 35 patients with ALLC (34 men, 1 woman; mean age, 58.9 ± 10.7 years; median age, 61 years; range: 37-76 years. All patients were enrolled in this study after obtaining written consent consent. Liver function was measured with tests measuring albumin (Alb), prothrombin time (PT), brain natriuretic peptide (BNP) acid and tyrosine ratio (BTR), branched chain amino acid (BCAA), tyrosine, ammonia (NH3), cholinesterase (ChE), immunoreactive insulin (IRI), total bile acid (TBA), and the retention rate of indocyanine green 15 min after administration (ICG R15). Hepatic blood flow, hepatic arterial tissue blood flow (HATBF), portal venous tissue blood flow (PVTBF), and total hepatic tissue blood flow (THTBF) were used calculated xenon computed tomography. , HATBF and THTBF were 30.2 ± 10.4, 20.0 ± 10.7, and 50.3 ± 14.9 m L / 100 m L / min, respectively. Alb , PT, BNP, BTR, BCAA, tyrosine, NH3, ChE, IRI, TBA and ICG R15 were 3.50 ± 0.50 g / d L, 72.0 ± 11.5, 63.2 ± 56.7 pg / m L, 4.06 ± 1.24, 437.5 ± 89.4μmol / L, 117.7 ± 32.8μmol / L, 59.4 ± 22.7μg / dL, 161.0 ± 70.8IU / L, 12.8 ± 5.0μg / dL, 68.0 ± 51.8μmol / L and 28.6% ± 13.5% , respectively.PVTBF showed a significant negative correlation with ICG R15 (r = -0.468, P <0.01) .No significant correlation was seen between ICG 15R, HATBF and THTBF.There was a significant correlation between PVTBF and Alb (r = 0.2499, P <0.05), and NH3 tended to have an inverse correlation with PVTBF (r = -0.2428, P = 0.0894). There were also many significant correlations between ICG R15 and liver function parameters including Alb, NH3, PT, BNP, TBA , BCAA, and tyrosine (r = -0.2156, P <0.05; r = 0.4318, P <0.01; r = 0.4140, P <0.01; r = 0.3610, , P <0.01; and r = 0.4740, P <0.05, respectively) .CONCLUSION: Our findings showed that there is a close correlation between liver function and hepatic blood flow.
