BACKGROUND/AIMS: Partial splenic embolization or splenectomy has been reported to improve liver function as well as hypersplenism. The aim of this study was to evaluate the effects of splenectomy in patients with liver cirrhosis (LC) on liver function. METHODOLOGY: Twelve consecutive patients with LC were followed for more than 6 months using laboratory examinations, ultrasonography (US) and computed tomography. Portal blood flow was measured using color Doppler US before and after splenectomy in 6 cases. RESULTS: Hypersplenism was improved in all patients. Protein synthesis in the liver was improved, which significantly correlated with these patients' increased liver volume. Having a large spleen and a low serum alanine aminotransferase (ALT) levels are predictive factors for favorable improvement of liver function after splenectomy. Splenectomy was safely carried out in all patients without major complications except for portal thrombus occurred in 4 patients, but did not affect liver function if it was well treated. CONCLUSIONS: Splenectomy improved liver function in patients with LC, and could be a supportive and bridging therapy for patients waiting for liver transplantation, especially with large spleen and lower ALT levels. 相似文献

OBJECTIVE: Cognitive impairment is a common problem in patients with liver cirrhosis. Its pathogenesis is multifactorial and ammonia is considered to play a central role. Renal function has been shown to be important for ammonia metabolism in cirrhosis. Although renal dysfunction is common in cirrhotic patients, its effect on cognitive function is largely unexplored. MATERIAL AND METHODS: A total of 128 consecutive cirrhotic patients were prospectively evaluated for the presence of cognitive dysfunction according to the West-Haven criteria and by means of two psychometric tests. Serum creatinine, sodium and potassium as well as plasma ammonia concentrations were assessed. Glomerular filtration rate was also measured by (51)Cr- EDTA clearance in a subgroup of patients. RESULTS: Forty-one patients (32%) were found to have cognitive dysfunction (clinical evaluation and/or psychometric tests). Sixteen patients (13%) found with serum creatinine levels above reference values had cognitive dysfunction more frequently than patients with creatinine within the normal range (69% versus 31%; p = 0.001), but did not differ in aetiology or severity of cirrhosis (p >0.1). Patients with loop diuretics versus without did not differ in creatinine values (p >0.1). Multivariate analysis showed that cognitive dysfunction was related to hospital admission at inclusion in the study, international normalized ratio and serum creatinine (p <0.05 for all), but not to potassium or sodium levels. Plasma ammonia concentration was related to serum creatinine (r = 0.26, p = 0.004) and the glomerular filtration rate (r = -0.44, p = 0.023). CONCLUSIONS: Renal dysfunction seems to be related to cognitive impairment in patients with liver cirrhosis and might be implicated in the pathogenesis of hepatic encephalopathy. 相似文献

BACKGROUND/AIMS: The aim of this study was to investigate whether C3 and C4 serum complement concentrations have prognostic relevance for patients with liver cirrhosis. METHODOLOGY: Serum complement concentrations of C3 and C4 were measured in 69 patients with liver cirrhosis and correlated with the Child-Pugh score. RESULTS: C3 concentrations were 1.06+/-0.21 g/L in patients with Child-Pugh A liver cirrhosis and significantly lower in Child-Pugh B (0.78+/-0.24 g/L) and even lower Child-Pugh C (0.49+/-0.14 g/L) (p=0.006 B vs. A, p<0.001 C vs. B). Patients with consecutive hepatorenal syndrome (HRS) had the lowest C3 concentrations (0.44+/-0.05 g/L (Child-Pugh C +HRS) vs. 0.54+/-0.06g/dL (Child-Pugh C -HRS); p<0.05). C4 concentrations were 0.21+/-0.08 in Child-Pugh A and significantly lower in Child-Pugh B (0.11+/-0.04) and Child-Pugh C (0.09+/-0.04) patients (p<0.001). There was a negative correlation between C3 (r = -0.81, p<0.001) and C4 (r = -0.51, p<0.05) concentrations and the Child-Pugh score. CONCLUSIONS: Serum complement concentrations of C3 and C4 correlate negatively with the Child-Pugh score in patients with liver cirrhosis. C3 concentrations are lower in those Child-Pugh C cirrhosis patients with consecutive development of HRS. 相似文献

Noninvasive quantitative testing of liver function using ultrasonography in patients with cirrhosis 总被引:1,自引:0,他引:1
BACKGROUND/AIMS: Chronic liver disease is characterized by progressive hepatic fibrosis and changes in hepatic hemodynamics. Although there are sufficient hemodynamic ultrasonography data about patients with liver cirrhosis, reports of combinations of these data are insufficient. This study aimed to address the possibility of noninvasive diagnosis for the degree of hepatic fibrosis by evaluating the ultrasonography score, HCI (Hepatic Circulation Index), A/P (The peak velocity of hepatic artery/The peak velocity of portal vein), and CAT (hepatic vein circulation time) in patients with cirrhosis. METHODOLOGY: 53 cirrhosis patients underwent ultrasonographically-guided liver biopsy to confirm the diagnosis of cirrhosis. Values were correlated with the ultrasonography score, blood fibrosis makers, metabolic liver function tests and Child-Pugh classification. RESULTS: 53 patients participated in this study. The fibrosis stage of a total of 53 patients was > or = S2; 22.6% of the patients (n= 12) had cirrhosis of Child-Pugh grade A, 41.5% of grade B (n=22) and 35.9% of grade C (n=19). Liver function showed a steady decrease from Child-Pugh grade A to grade B and to grade C. In contrast, ultrasonography score was significantly increased in Child-Pugh grade A, B and C patients compared to healthy controls. Differences between the three Child grades were significant. CONCLUSIONS: Ultrasonography score and A/P correlated with Child-Pugh grades and HCI, CAT correlated inversely with Child-Pugh grades so they may be useful tools to predict prognosis or complications in cirrhosis. 相似文献

The effect of propranolol on thyroid hormones of 7 healthy subjects and 10 patients with histologically proven alcoholic liver cirrhosis was investigated. The fractions of plasma T3 and free T4 were determined by specific radioimmunoassay before and after two weeks of propranolol administration. Under basal conditions, both T3 and FT4 levels were found significantly lower in patients with cirrhosis than in healthy subjects (1.86 +/- 0.10 vs. 1.18 +/- 0.41 nmol/l, p less than 0.001; 9.31 +/- 0.41 vs. 8.17 +/- 0.91 pg/ml, p less than 0.05, respectively). In healthy subjects propranolol administration led to a significant reduction of T3 serum levels (from 1.88 +/- 0.10 to 1.51 +/- 0.12 nmol/L, p less than 0.001), while in patients with liver cirrhosis no significant changes in T3 and FT4 were found. In patients with liver cirrhosis propranolol administration did not affect thyroid hormone levels. 相似文献

BACKGROUND: Spider angioma is a common sign in patients with liver cirrhosis, but the pathogenesis is still unclear. Alcohol and hyperestrogenemia are both possible etiologies. This study was designed to investigate the relationship of spider angiomas in patients with liver cirrhosis to alcohol, liver function test results, and plasma levels of sex hormones. METHODS: Eighty-two patients with liver cirrhosis and 18 healthy subjects were enrolled in this study. The number, size, and location of the spider angiomas were recorded for all subjects. Plasma levels of estradiol and testosterone were measured. RESULTS: Cirrhotic patients had significantly higher estradiol/testosterone ratios (26.8 +/- 5.1 x 10(-3) versus 8.8 +/- 2.0 x 10(-3); P = 0.002) than healthy controls. Twenty-seven (33%) of the 82 cirrhotic patients had spider angiomas. Cirrhotic patients with spider angiomas were younger (56 +/- 3 versus 66 +/- 1 years; P = 0.002) and had higher serum bilirubin levels (3.3 +/- 0.6 versus 1.7 +/- 0.2 mg/dl; P = 0.002), longer prothrombin time (16.8 +/- 0.8 versus 14.8 +/- 0.4 sec; P = 0.01), and higher prevalence of alcoholism (41% versus 20%; P = 0.04) than those without. Stepwise logistic regression showed that alcoholism and serum bilirubin level were the only significant and independent predictors associated with the presence of spider angiomas in cirrhotic patients (odds ratio = 3.5; 95% confidence interval = 1.2-10.8; P = 0.03, and odds ratio = 2.8; 95% confidence interval = 1.3-5.7; P = 0.006, respectively). CONCLUSIONS: Alcoholism and impaired liver function are important predictors of the presence of spider angiomas in patients with liver cirrhosis. 相似文献

Renal function and plasma antidiuretic hormone (ADH) levels were studied basally and after oral water load in four groups of subjects: 15 healthy controls (group I), 15 cirrhotics without ascites (group II), 15 cirrhotics with ascites (group III), and 10 decompensated cirrhotics with hyponatremia (group IV). Renal function and ADH levels were normal in group II. In groups III and IV water diuresis and fractional proximal sodium excretion were significantly decreased, whereas fractional distal sodium resorption and fractional excretion of potassium did not differ from those of controls. Basal ADH was significantly increased only in patients of group IV. In these patients ADH remained abnormally high after water loading. ADH did not correlate with water diuresis, plasma osmolality, mean arterial pressure, and plasma renin activity. We conclude that impaired water excretion in decompensated cirrhotics without hyponatremia cannot be ascribed to high serum levels of ADH. On the contrary, it seems to be related mainly to a reduced delivery of filtrate to the diluting segment of the nephron. In cirrhotic patients with hyponatremia high levels of ADH may play an additional role. 相似文献
