ALCOHOLISM, Issue 2010
Hideaki Takahashi
Background/Aims:, Xenon computed tomography (Xe-CT) is a noninvasive method of quantifying and visualizing tissue blood flow (TBF). For the liver, Xe-CT allows separate measurement of hepatic arterial and portal venous TBF. The present study evaluated the usefulness of Xe-CT as a noninvasive diagnostic procedure for measuring hepatic TBF in alcoholic liver cirrhosis (AL-LC), compared with liver cirrhosis related to nonalcoholic steatohepatitis (NASH), (NASH-LC), and hepatitis C virus (HCV), (C-LC). Methods:, Xe-CT was performed on 22 patients with AL-LC, 7 patients with NASH-LC, and 24 patients with C-LC. Severity of LC was classified according to Child-Pugh classification. Correlations between hepatic TBF, Child-Pugh classification, and indocyanin green retention (ICG) rate after 15 minutes (ICG15R) were examined. Correlations of hepatic TBF in Child-Pugh class A to AL-LC, NASH-LC, and C-LC were also examined. Results:, Portal venous TBF (PVTBF) displayed a significant negative correlation with Child-Pugh score and ICG15R (r = ,0.432, p < 0.01, r = ,0.442, p < 0.01, respectively). Moreover, ICG15R displayed a significant positive correlation with Child-Pugh score (r = 0.661, p < 0.001). Meanwhile, mean PVTBF and total hepatic TBF (THTBF) was significantly lower in AL-LC than in C-LC (p < 0.05). Mean PVTBF was significantly lower in Child-Pugh class A to AL-LC and NASH-LC than in that to C-LC (p < 0.05). Similarly, mean THTBF was significantly lower in Child-Pugh class A to NASH-LC than in that to C-LC (p < 0.05). Conclusions:, Measurement of hepatic TBF using Xe-CT is useful as a noninvasive, objective method of assessing the state of the liver in chronic liver disease. [source]

A Functional Polymorphism of the NFKB1 Gene Increases the Risk for Alcoholic Liver Cirrhosis in Patients With Alcohol Dependence

ALCOHOLISM, Issue 11 2009
Miguel Marcos
Background:, The genetic basis for the predisposition to alcoholic liver cirrhosis (ALC) remains unknown. Increasing evidence supports a role for the nuclear factor (NF)-,B, the NF-,B inhibitor , (NFKBIA), and the peroxisome proliferator-activated receptor (PPAR)-, in the pathogenesis of alcoholic liver disease, raising the possibility that common polymorphisms in genes encoding these molecules may confer susceptibility to ALC. The objective of this study was to analyze the relationship between common polymorphisms in NFKB1, NFKBIA, and PPARG2 genes and the presence of ALC. Methods:, A total of 258 male alcoholics (161 without liver disease and 97 with ALC) and 101 healthy controls were genotyped for the ,94ins/delATTG NFKB1, 3,-UTR+126G>A NFKBIA, and 34C>G PPARG2 polymorphisms. The association of these genetic variants with ALC was tested in alcoholic patients with alcohol abuse and alcohol dependence. A logistic regression analysis was further performed to analyze the model of inheritance. Results:, We found an association between the presence of the deletion allele in NFKB1 polymorphism and ALC in patients with alcohol dependence. We found no association between NFKBIA and PPARG2 polymorphisms and the presence of ALC. Conclusions:, The deletion allele of the ,94ins/del NFKB1 polymorphism could be associated with a higher risk of developing ALC through an increase in inflammation, as supported by previous data.

Clinical Characteristics of Portal Hemodynamics in Alcoholic Liver Cirrhosis

ALCOHOLISM, Issue 2004

Background: Low incidence of reversal blood flow at the portal vein has been reported by measurement in larger and extrahepatic blood vessels but not in intrahepatic blood vessels in patients with liver cirrhosis. Moreover, there is little information regarding the incidence of reversal blood on the basis of the cause of liver cirrhosis. The aim of this study was to measure the reversal blood flow in the portal vein including intrahepatic branches in patients with alcoholic and viral cirrhosis. Methods: The blood flow in the portal vein and existence of portosystemic shunt were studied in 52 and 27 patients with alcoholic and viral cirrhosis, respectively, by Doppler ultrasonography. The parameters of liver function test and the prevalence of ascites and esophageal varices were compared between patients with and without reversal blood flow. Results: Reversal blood flow at the portal vein was found only in patients with only alcoholic cirrhosis (17 of 52 patients) but not in any patients with viral cirrhosis (0 of 27 patients; p < 0.05). The incidence of portosystemic ascites and red color of esophageal varices was also higher in patients with alcoholic cirrhosis with reversal blood flow in the portal vein compared with patients without reversal blood flow (p < 0.05). Conclusions: Reversal blood flow in the portal vein is a characteristic feature of alcoholic cirrhosis. The presence of reversal blood flow indicates severe liver diseases, and this feature may have prognostic importance for patients with alcoholic cirrhosis. [source]

Granulomatous cryptococcal prostatitis diagnosed by transrectal biopsy

INTERNATIONAL JOURNAL OF UROLOGY, Issue 5 2006
ILL YOUNG SEO
Abstract, Cryptococcal infection primarily involves the lung and is hematogenously spread to other organs. Sometimes it might affect the genitourinary tract, and rare cases have been reported involving the prostate without systemic infection. We report a case of granulomatous prostatitis as a result of Cryptococcus neoformans yeast in an immunocompromised patient with alcoholic liver cirrhosis, which was diagnosed by transrectal ultrasound guided biopsy and treated with antifungal medication.

Background:, The diverse incidence of alcoholic cirrhosis around the world and the fact that not all alcoholic drinkers develop liver disease indicates that genetic and environmental factors play an important role in the development of liver cirrhosis. Lipids participate in early stages of alcoholic cirrhosis. Therefore variations in the plasma lipid profile due to primary (genetic) or secondary (environmental) dyslipidemia could affect the development of liver disease. The aim of this study was to analyze the lipid profile and apolipoprotein E (APOE) polymorphism in patients with alcoholic liver cirrhosis (AC) and determine the risk associated with genotype polymorphism with the onset of alcoholic cirrhosis. Methods:, In a case and control study, 86 patients with AC divided into hyperlipidemic (H) and non-hyperlipidemic (non-H) groups, and 133 healthy individuals (C) matched by age and sex were studied. Lipid profile and liver function tests were measured by enzymatic methods. The APOE genotypes were identified by PCR-RFLP,s. Results:, A statistically significant increase of the APOE*2 allele and genotypes 2/2, 2/3, and 2/4 was present in AC patients compared to C group. A hyperlipidemic state characterized by increased levels of triglycerides and apolipoprotein B (APOB) and a decrease of high density lipoprotein-cholesterol (HDL-c) was detected in young-aged patients (31.2 ± 6.2 years old vs. 46.3 ± 12.5 years old). In this group, hypertriglyceridemia was closely associated to APOE*2 allele and to an early onset of liver cirrhosis. By contrast, APOE*4 allele was associated with a longer duration of alcohol intake (>20 years) in the non-H group. Conclusions:, This study shows the association of hypertriglyceridemia and APOE allele with the early onset of alcoholic liver cirrhosis, and the interaction between environmental factors, such as duration of alcohol abuse and amount of alcohol intake, and genetic factors (APOE*2 allele) on the hypertriglyceridemic process.

Mean Corpuscular Volume and ADH1C Genotype in White Patients With Alcohol-Associated Diseases

ALCOHOLISM, Issue 5 2005

Background: Alcohol abuse is associated with several gastrointestinal diseases, such as esophageal carcinoma, chronic alcoholic pancreatitis, and liver cirrhosis. Increased mean corpuscular volume (MCV) has been recognized as a biomarker for alcohol abuse and heavy drinkers. Recent studies from Japan revealed that macrocytosis is related to ALDH-2/2 genotype, leading to increased acetaldehyde accumulation. It has also demonstrated that increased MCV values could also be an independent biomarker for esophageal cancer in Asians. Therefore, the aim of the current study was to investigate possible associations of MCV value with polymorphisms of ADH1C in white patients with alcohol-associated esophageal carcinoma, chronic alcoholic pancreatitis, and alcoholic cirrhosis as well as in heavy drinkers without organ damage. Methods: In this study, a total of 510 alcoholic patients were enrolled with esophageal cancer (n= 98), chronic pancreatitis (n= 98), alcoholic liver cirrhosis (n= 151), and alcohol abuse without gastrointestinal disease (n= 163). ADH1C genotyping was performed by PCR-based restriction fragment length polymorphism (PCR-RFLP) analysis from whole blood. The relation between MCV and ADH1C gene polymorphisms (ADH1C*1 and 1C*2) controlled for the amount of drinking, smoking, and age were investigated using both univariate and multivariate analysis. Results: In univariate analysis, higher alcohol consumption was associated with increased MCV. Other variables were not associated with macrocytosis. In multiple linear regression analysis, after adjustment for age and smoking, higher alcohol consumption and female sex were independently associated with higher MCV values. No other variables, including which alcohol-associated disease the patient had, had an independent effect. Adding ADH genotype rendered no independent significant effect on MCV value. Conclusions: In a white population, MCV values were not associated with genotype polymorphisms of ADH1C. In contrast to findings in Asians, macrocytosis does not seem to be an independent biomarker for esophageal cancer. The role of ADH1C polymorphism in increasing MCV and the potential use of MCV as a marker for esophageal carcinoma are still pending. [source]
