The relationships between the serum mineral concentrations and the endoscopic findings of esophageal varices have been poorly investigated. In this study, we investigated hepatitis virus-positive patients who had undergone a liver biopsy (n = 576) and 75 patients with compensated cirrhosis in order to evaluate the association of the zinc value with the severity of liver fibrosis and esophageal varices. The mean zinc values decreased with the progression of fibrosis (METAVIR score; F0–1: 71.3 ± 11.3, F2: 68.9 ± 11.7, F3: 66.3 ± 11.8, F4: 63.9 ± 15.0). In the hepatitis virus-related compensated cirrhosis, the mean zinc value decreased with the severity of varices (patients without varices: 66.3 ± 12.6, patients with low-risk varices: 62.5 ± 13.7, patients with high-risk varices: 55.6 ± 13.0). The zinc value was significantly lower in patients with varices than in those without varices (59.3 ± 13.6 vs 66.3 ± 12.6, p<0.05). The zinc value was also significantly lower in the patients with a high risk of bleeding than in those with a low risk (55.6 ± 13.0 vs 64.6 ± 13.1, p<0.01). These findings suggest that the zinc value is not only an indicator of an abnormal metal metabolism, but is also a simple parameter associated with hepatitis virus-related various conditions, including the degree of liver fibrosis and the severity of esophageal varices in compensated cirrhosis.  相似文献

BackgroundEndoscopy has long been widely used to screen for esophageal varices (EV) in cirrhotic patients. Recurrent endoscopy is a significant burden for the healthcare system of the endoscopic unit as well as uncomfortable and high costs for patients. This study intended to prognosticate Right Liver Lobe Diameter/Serum Albumin Ratio (RLLD/Alb) as a non‐invasive approach in the early diagnosis of EV among chronic liver disease (CLD) Bangladeshi patients enrolled in a specific hospital.Participants and MethodsA total of 150 admitted patients with CLD were included in the study. Patients were subjected through a comprehensive biochemical checkup and upper digestive endoscopic or ultrasonographic inspection. The correlation was evaluated between the RLLD/Alb ratio and esophageal varices grades.ResultsThe upper digestive endoscopy demonstration among 150 patients resulted in no EV in 18%, while 24% of patients was identified as EV grade I, 20% as grade II, 20% as grade III, and 18% patients as grade IV. The mean value of the RLLD/Alb ratio was 4.89 ± 1.49 (range from 2.30 to 8.45). The RLLD/Alb ratio diagnosed the EV employing the cut‐off value of 4.01 with 85.3% sensitivity and 68.8% specificity. Furthermore, it was positively correlated with the grading of EV, when this ratio increased the grading of EV increases and vice versa (r = 0.630, p < 0.001).ConclusionThe RLLD/Alb ratio is a non‐invasive parameter giving exact guidance relevant to the ascertainment of the existence of EV and their grading in chronic liver disease patients.  相似文献

The risk and speed of progression from fibrosis to compensated and decompensated cirrhosis define the prognosis in liver diseases. Therefore, early detection and preventive strategies affect outcomes. Patients with liver disease have traditionally been diagnosed at an advanced stage of disease, in part due to lack of non-invasive markers. Ultrasound elastography to measure liver stiffness can potentially change this paradigm. The purpose of this review was therefore to summarize advances in the field of ultrasound elastography with focus on diagnosis of liver fibrosis, cirrhosis and clinically significant portal hypertension, techniques and limitations. Four types of ultrasound elastography exist, but there is scarce evidence comparing the different techniques. The majority of experience concern transient elastography for diagnosing fibrosis and cirrhosis in patients with chronic viral hepatitis C. That said, the role of elastography in other aetiologies such as alcoholic- and non-alcoholic liver fibrosis still needs clarification. Although elastography can be used to diagnose liver fibrosis and cirrhosis, its true potential lies in the possibility of multiple, repeated measurements that allow for treatment surveillance, continuous risk stratification and monitoring of complications. As such, elastography may be a powerful tool for personalized medicine. While elastography is an exciting technique, the nature of ultrasound imaging limits its applicability, due to the risk of failures and unreliable results. Key factors that limit the applicability of liver stiffness measurements are as follows: liver vein congestion, cholestasis, a recent meal, inflammation, obesity, observer experience and ascites. The coming years will show whether elastography will be widely adapted in general care.  相似文献

Evaluation of: Fontana RJ, Sanyal AJ, Ghany MG et al. Factors that determine the development and progression of gastroesophageal varices in patients with chronic hepatitis C. Gastroenterology 138(7), 2321–2331 (2010).

Hepatitis C virus infection is the leading cause of chronic liver disease in the western world. Chronic liver diseases may cause, through portal hypertension, the development of gastroesophageal varices, which can then bleed. We assess the findings of a study aimed at identifying the incidence of de novo varix development and their progression in patients with chronic hepatitis C and advanced fibrosis. This study was a substudy of the Hepatitis C Antiviral Long-Term Treatment against Cirrhosis (HALT-C) trial. The HALT-C trial was designed to determine whether pegylated interferon (PEG-IFN) at low dose can reduce the rate of disease progression in these patients. Approximately 26% of patients developed de novo varices and 35.2% of patients with varices at baseline had variceal progression or bleeding during the 4-year follow-up. The authors examine demographic, clinical, laboratory, virological, endoscopic and histological factors associated with the development and progression of gastroesophageal varices. PEG-IFN-α2a therapy did not reduce the risk of development or progression of gastroesophageal varices.  相似文献

BACKGROUND: Chronic liver disease is characterized by progressive hepatic fibrosis and changes in hepatic haemodynamics. This study has addressed the possibility of a noninvasive diagnosis of the degree of hepatic fibrosis by evaluating the velocity of blood in the hepatic vasculature. Materials and methods The maximum velocity of blood at the portal vein and hepatic artery was measured in 80 patients with chronic liver diseases (19 with liver cirrhosis; 61 with chronic hepatitis) and in 20 normal volunteers by Doppler ultrasonography. The arterio-portal ratio (A/P ratio) was calculated by dividing the maximum velocity of blood (Vmax) in the hepatic artery with the Vmax in the portal vein. Multivariate analysis was used to disclose the independent predictors of the degree of hepatic fibrosis. RESULTS: The levels of A/P ratio were significantly higher in patients with liver cirrhosis (LC) compared to those with chronic hepatitis (CH) and normal controls. Probit analysis revealed that the value of A/P ratio at which CH becomes LC was A/P >or= 3.5. The levels of A/P ratio were also significantly higher in patients with severe fibrosis compared with mild (P < 0.0001) and moderate (P < 0.0001) fibrosis. Multivariate analysis disclosed right A/P ratio (P = 0.0001), left A/P ratio (P = 0.013), and platelet counts (P = 0.0172), as the only independent predictors of the degree of hepatic fibrosis. CONCLUSIONS: A/P ratio may be used for the noninvasive diagnosis of the degree of hepatic fibrosis in patients with chronic liver diseases.  相似文献

OBJECTIVES: Progression of liver fibrosis to cirrhosis is a dire consequence of chronic liver diseases (CLD). Nepsilon-(carboxymethyl)lysine (CML)-modified advanced glycation end products (AGEs) in patients with CLD could reflect the degree of severity of the disease. DESIGN AND METHODS: In 110 patients with CLD and 124 healthy controls, CML serum levels and their diagnostic sensitivity and specificity were determined and compared to hyaluronan (HA). RESULTS: Serum levels of CML were significantly affected by the stage of liver cirrhosis and were closely associated with liver function capacity. CML correlated positively with HA (r = 0.639, P < 0.0001). In ROC analysis, the diagnostic sensitivity and specificity in distinguishing healthy controls from liver disease patients for CML (AUC 0.908; 95%-CI 0.863-0.942, cut-off 640 ng/mL, sensitivity 74.5% and specificity 97.6%) resembled HA (AUC 0.948; 95%-CI 0.907-0.974; cut-off 50 ng/mL, sensitivity 80.7% and specificity 97.9%). The combination of CML and HA shows an AUC of 0.932; 95%-CI 0.888-0.962; sensitivity 82.6%; and specificity 95.8%. CONCLUSIONS: Our data suggest that serum levels of CML could provide a supplementary diagnostic marker for advanced stages of liver cirrhosis. However, the quality of interaction needs further investigation.  相似文献

Ammonia and glutamine metabolism was studied in slices from normal, fatty and cirrhotic human livers. The liver disease was evaluated by histological examination. With respect to ammonia removal, urea and glutamine synthesis in human liver represent low and high affinity systems with k0.5(NH4+) values of 3.6 and 0.11 mM, respectively. Compared with normal control livers, cirrhotic livers showed a decreased glutamine synthesis from NH4Cl by about 80%. The same was true for urea synthesis. Conversely, flux through hepatic glutaminase was increased in cirrhosis 4-6-fold. These changes in hepatic glutamine and ammonia metabolism were observed regardless of whether reference was made to liver wet weight, DNA or protein content. Acetazolamide inhibited urea synthesis in cirrhotic liver slices by about 50%, indicating that mitochondrial carbonic anhydrase is required for urea synthesis also in cirrhosis. There was a significant correlation between the in-vitro determined capacity for urea synthesis from NH4Cl and the in-vivo determined plasma bicarbonate concentration.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

To investigate whether observing the morphology of the peripheral hepatic vasculature and the hemodynamics of microbubble arrival time in these vessels can provide useful information for the diagnosis of liver disease, Five normal volunteers and 16 patients were studied by contrast-enhanced coded phase-inversion harmonic sonography. Vessel images of the peripheral vessels were observed in real time after intravenous injection of Levovist. The time when the microbubbles appeared in the peripheral vessels was measured. Three patterns of morphologic change of the peripheral hepatic vasculature were seen, marked, slight, and no abnormal changes. The microbubble arrival times at the peripheral vessels were all shorter in patients with cirrhosis than chronic hepatitis or normal subjects. Marked, slight, and no abnormal morphologic changes of the peripheral hepatic vasculature in patients with liver cirrhosis were found in five, one and zero of the six patients, respectively. Those patients with chronic hepatitis, were found in one, six and three of the ten patients, respectively. There was a significant difference among the different groups (P < 0.001). Evaluating the hemodynamics and morphology by contrast-enhanced coded pulse-inversion harmonic sonography may offer useful information in the diagnosis of liver disease.  相似文献

ObjectivesThe aim of this study was to compare the correlation of gamma‐glutamyl transpeptidase‐to‐platelet ratio (GPR), aspartate aminotransferase‐to‐platelet ratio index (APRI), fibrosis index‐4 (FIB‐4), and liver stiffness measurement (LSM) in the diagnosis of liver fibrosis, and perform a diagnostic value of GPR for predicting fibrosis in CHB patients with NAFLD.MethodsA retrospective study was conducted on CHB patients concurrent with NAFLD between September 2019 and December 2020. They were divided into control group (LSM ≤ 9.7 kpa) and fibrosis group (LSM ≥ 9.8 kpa). Demographic data were collected; ALT, AST, and PLT were also detected. LSM was measured by transient elastography (TE). The GPR, APRI, and FIB‐4 were calculated. The correlation between GPR, APRI, FIB‐4, and LSM was compared. The accuracy of predicting liver fibrosis using GPR, APRI, and FIB‐4 was assessed.ResultsEighty‐five CHB patients with NAFLD were enrolled. Multivariate analysis showed that age (p = 0.005), GGT (p = 0.001), and PLT (p = 0.013) were the independent risk factors for LSM. The GPR (p = 0.008), APRI (p = 0.001), and FIB‐4 (p = 0.001) values in fibrosis group were higher than control group. Pearson linear correlation was used to analyze the correlations between LSM and GPR, APRI, and FIB‐4. LSM was correlated with GPR, APRI, and FIB‐4. The AUCs of GPR, APRI, and FIB4 were 0.805, 0.766, and 0.826 in assessing liver fibrosis, respectively. No significant differences in the areas of GPR were comparable to that of APRI and FIB‐4.ConclusionGPR has a good correlation with LSM in assessing liver fibrosis and can be used as a noninvasive index for the assessment of liver fibrosis in patients with concomitant CHB and NAFLD.  相似文献
