- Non-cirrhotic portal hypertension - Concept, diagnosis and clinical management(2014) STRAUSS, Edna; VALLA, DominiqueNon-cirrhotic portal hypertension (NCPH) is mainly related to vascular disorders in the portal system, granuloma formation with periportal fibrosis or genetic alterations affecting the hepatobiliary system. For the diagnosis of the so-called idiopathic NCPH, it is essential to rule out chronic liver diseases associated with progression to cirrhosis as viral hepatitis B and C, alcoholic and non-alcoholic fatty liver, autoimmune disease, hereditary hemochromatosis, Wilson's disease as well as primary biliary cirrhosis and primary sclerosing cholagitis. This mini review will focus on the most common types of NCPH, excluding the idiopathic NCPH. Primary Budd-Chiari syndrome, characterized by obstruction of hepatic venous outflow, must be distinguished from sinusoidal obstruction syndrome, a cause of portal hypertension associated with exposure to toxic plants or therapeutic agents. Noninvasive imaging methods usually help the diagnosis of both Budd-Chiari syndrome and portal thrombosis, the later a relatively frequent cause NCPH. Clinical presentation and management of these vascular disorders are evaluated. Schistosomiasis, a worldwide spread endemic parasitic disease, may evolve to severe forms of the disease with huge spleen and gastroesophageal varices due to presinusoidal portal hypertension. Although management of acute upper gastrointestinal bleeding is similar to that of cirrhosis, prevention of rebleeding differs. Instead of portosystemic shunt procedures, the esophagogastric devascularization with splenectomy is the accepted surgical alternative. Its association with endoscopic therapy is suggested to be the best option for PH due to schistosomiasis. In conclusion, the prompt diagnosis of the disorder leading to non-cirrhotic portal hypertension is essential for its correct management.

- Altered quality of life in the early stages of chronic hepatitis C is due to the virus itself(2014) STRAUSS, Edna; PORTO-FERREIRA, Francisco Augusto; ALMEIDA-NETO, Cesar de; TEIXEIRA, Maria Cristina DiasHealth-related quality of life (HRQOL) is impaired in chronic viral hepatitis and a direct role of the virus, although suggested, has not been demonstrated. Our aim was to evaluate HRQOL at blood donation before knowledge of the diagnosis of both hepatitis C virus (HCV) and hepatitis B virus (HBV) so as to elucidate this matter. Methods: Prospectively, 67 sequential patients, 35 with HCV and 32 with HBV, and 67 matched controls were administered the generic Short Form-36 (SF-36) questionnaire. After knowledge of diagnosis, the SF-36 was repeated and a disease-specific questionnaire (Liver Disease Quality of Life, LDQOL-1.0) was also administered. The Wilcoxon test and Mann-Whitney U were used for between-group comparisons. Results: Before knowledge of diagnosis, patients with HCV had worse HRQOL than controls, with statistically significant changes in 7/8 domains of the SF-36, and also in its physical and mental components. In the HBV group, only 2/8 domains and the physical component were significantly different from controls. After diagnosis, similar changes persisted in the HCV group, whereas two more domains were compromised in the HBV group. Comparisons between the HCV and HBV groups did not show significant differences. Conclusion: The finding of greater HRQOL impairment in the HCV group before diagnosis confirms the theory that the presence of HCV in the early stage of the disease is associated with worse quality of life.
