Hepatic Cirrhosis (hepatic + cirrhosis)
Selected AbstractsEffect of , -Interferon and , -Tocopherol in Reversing Hepatic Cirrhosis in RatsANATOMIA, HISTOLOGIA, EMBRYOLOGIA, Issue 2 2007T. C. Mathew Summary The aim of this study was to assess the effects of , -interferon and , -tocopherol (vitamin E), or a combination of both, in reversing hepatic fibrosis following the induction of cirrhosis using thioacetamide by histological and biochemical analysis. Fifty male Wistar rats were used in this study. The animals were divided equally into five groups. Animals in group I were used as controls. The remaining animals (groups II,V) were provided with 0.5 g/L of thioacetamide in order to induce liver cirrhosis. Group II animals were used as the cirrhotic control. Animals of groups III, IV and V were given , -interferon, , -tocopherol and interferon together with , -tocopherol, respectively, for 30 days. After 30 days the animals were killed and following gross morphological examination of the liver, the hepatic tissues were processed for histological analysis and the serum was used for liver function tests. Morphological analysis showed a decrease in the number of nodules on the surface of the liver in both interferon- as well as vitamin E-treated cirrhotic rats. Histopathological analysis showed that the abnormalities of the cirrhotic liver were partially reversed and liver function tests showed an overall improvement following treatment of animals of groups III, IV and V. Combination therapy using both interferon and , -tocopherol did not have any substantial effect on the rats compared with that when they were given separately. These findings suggest that , -interferon and , -tocopherol may have therapeutic value in reversing liver cirrhosis.

Poldervaart Background: Little is known about etiology, disease progression, treatment outcome, survival time, and factors affecting prognosis in dogs with primary hepatitis (PH). Objectives: To review retrospectively different forms of hepatitis in a referral population, by the World Small Animal Veterinary Association Standardization criteria. Animals: One-hundred and one dogs examined for histologically confirmed PH between 2002 and 2006. Dogs with nonspecific reactive hepatitis were excluded. Methods: Retrospective study. Medical records were reviewed for prevalence, signalment, clinical and clinicopathologic manifestation, outcome, survival time, and prognostic factors for shortened survival. Results: PH occurred in 0.5% of dogs in this referral population. Acute (AH) and chronic hepatitis (CH) were diagnosed in 21 and 67 dogs, respectively. Progression from AH to CH occurred in 5/12 of the repeatedly sampled dogs. CH was idiopathic in 43 (64%) dogs, and was associated with copper accumulation in 24 (36%) dogs. Median survival time was longer in dogs with AH than in dogs with CH (either idiopathic or copper associated), and dogs with lobular dissecting hepatitis had the shortest survival time. Prognostic factors predicting shortened survival were associated with decompensated liver function and cirrhosis at initial examination. Conclusions and Clinical Importance: The majority of PH in dogs is CH. Previous studies appear to have underestimated the etiologic role of copper in both AH and CH. Prognosis is reduced in dogs with hepatic cirrhosis or cirrhosis-related clinical findings. Further research into etiology and treatment effectiveness in all PH forms is needed. [source] Review article: primary prophylaxis for portal hypertensive bleeding in cirrhosisALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 7 2000Vlachogiannakos Variceal bleeding is a consequence of portal hypertension, which in turn is the major complication of hepatic cirrhosis. Given the high rate of mortality of the first bleeding episode, primary prophylaxis to prevent bleeding from varices and portal hypertensive gastropathy is the current optimal therapeutic approach. The difficulty in identification of patients with varices who will bleed, before they do so, can justify a strategy of treating all patients with varices prophylactically. We evaluated the various therapies that have been assessed in randomized controlled trials for prevention of first bleeding, using meta-analysis where applicable. The current first choice treatment is non-selective ,-blockers; it is cheap, easy to administer, and is effective in preventing the first variceal haemorrhage and bleeding from gastric mucosa. Combination drug therapy of ,-blockers and nitrates looks promising, but needs further evaluation in randomized controlled trials. The conflicting results of the randomized studies of endoscopic banding ligation and the small number of patients and clinical events, as well as the cost, do not warrant any change in current practice. However, endoscopic banding ligation may be a reasonable alternative for patients who cannot tolerate, or have contraindications to ,-blockers or no haemodynamic response to the drug therapy, but this must be proved in randomized trials. [source] Hepatopulmonary syndrome associated with autoimmune liver cirrhosisRESPIROLOGY, Issue 2 2001Nobukazu Takada A 46-year-old woman presented for evaluation of liver dysfunction and dyspnoea. Laboratory examination showed high levels of ,-globulin, immunoglobulin (Ig)G, and antinuclear antibodies. Laparoscopy demonstrated hepatic cirrhosis. Despite normal spirometry, hypoxaemia (which was worse in standing position) and a low diffusing capacity were present. The shunt ratio calculated using arterial blood gas was 6.4%, but was 40% when measured using 99mTc-macroaggregated albumin scanning. The discrepancy between the ratios indicated that hypoxaemia was caused by intrapulmonary vascular dilatation. The patient was diagnosed with hepatopulmonary syndrome associated with autoimmune liver cirrhosis. [source] Searching for Links between Endotoxin Exposure and Pregnancy Loss: CD14 Polymorphism in Idiopathic Recurrent MiscarriageAMERICAN JOURNAL OF REPRODUCTIVE IMMUNOLOGY, Issue 4 2003Jari Karhukorpi Problem: Lipopolysaccharide (LPS) (endotoxin) is a well-known inducer of abortions in mice. In addition it has been proposed that gut-derived LPS of gram-negative bacteria may play a role in triggering idiopathic recurrent miscarriage (IRM) in humans. CD14 is one of the key molecules that mediates the effects of LPS. Promoter region polymorphism (,159C/T) in the CD14 gene is functionally important by regulating CD14 levels. High-producing CD14 genotype (TT) associates with deleterious effects of gut-derived LPS in hepatic cirrhosis in humans. It is not known whether women with IRM are genetically more prone to suffer from toxic effects of LPS. Method of study: By using polymerase chain reaction we analyzed the CD14 promoter region polymorphism in 38 women with IRM and in 127 normal controls of Finnish origin. Results: There were no significant differences in the CD14(,159C/T) allele or the genotype frequencies between the IRM women and the controls. However, there was a trend associating the presence of the T allele with increased odds of miscarriage. Conclusions: Although we were not able to find a statistically significant association between CD14 genotypes and IRM in our relatively small study population, a further study with a larger sample size is warranted to explore the role of high-producing CD14 genotypes in IRM. Also studies highlighting environmental LPS triggers and other intrinsic mediators of LPS signalling are needed to solve the enigmatic role of LPS in IRM in humans. [source] Reversal of Cardiac Cirrhosis Following Orthotopic Heart TransplantationAMERICAN JOURNAL OF TRANSPLANTATION, Issue 6 2008M. G. Crespo-Leiro Irreversible hepatic cirrhosis greatly increases the risks attending heart transplantation (HT), and is accordingly considered to be an absolute contraindication for HT unless combined heart and liver transplantation can be performed. It is now recognized that hepatic cirrhosis can undergo regression if the source of insult is removed, but no cases of post-HT regression of cirrhosis of cardiac origin have hitherto been reported. Here we report a case of cardiac cirrhosis that underwent complete regression following orthotopic HT, and we discuss the implications of this case. [source] Effect of breed on anatomy of portosystemic shunts resulting from congenital diseases in dogs and cats: a review of 242 casesAUSTRALIAN VETERINARY JOURNAL, Issue 12 2004GB HUNT Objective To evaluate the effect of species and breed on the anatomy of portosystemic vascular anomalies in dogs and cats. Design Retrospective study of 233 dogs and nine cats presenting to the University Veterinary Centre, Sydney. Methods Case records were evaluated for breed, sex, age, anatomical and histological diagnosis. Cases were included when a portosystemic vascular anomaly resulted from a congenital or developmental abnormality of the liver or portal venous system. Results Disease conditions included single congenital portosystemic shunt with patent portal vasculature (214 dogs, nine cats), portal vein aplasia (nine dogs), multiple acquired shunts resulting from portal vein hypoplasia (seven dogs), biliary atresia (one dog) and microvascular dysplasia (one dog). One Maltese had a single, congenital shunt and multiple acquired shunts resulting from hepatic cirrhosis. Breeds that were significantly over-represented included the Maltese, Silky Terrier, Australian Cattle Dog, Bichon Frise, Shih Tzu, Miniature Schnauzer, Border Collie, Jack Russell Terrier, Irish Wolfhound and Himalayan cat. Bichon Frise with shunts were significantly more likely to be female than male (12:2, P < 0.001). Two hundred and fourteen dogs (91.4%), and all cats, had shunts that were amenable to attenuation. Inoperable shunts occurred in 19 dogs (8.2%). Fifty six of 61 (92%) operable shunts in large breed dogs were intrahepatic, versus 10/153 (7%) in small breeds (P < 0.0001). Breeds that were not predisposed to portosystemic shunts were significantly more likely to have unusual or inoperable shunts than dogs from predisposed breeds (29% versus 7.6%, P < 0.0001). No significant relationship between breed and shunt type could be determined in cats. Conclusion Breed has a significant influence on shunt anatomy in dogs. Animals presenting with signs of portosystemic shunting may suffer from a wide range of operable or inoperable conditions. Veterinarians should be aware that unusual or inoperable shunts are much more likely to occur in breeds that are not predisposed to congenital portosystemic shunts. [source] |
