14. Effects of the administration of pentoxifylline and prednisolone on the evolution of portal fibrogenesis secondary to biliary obstruction in growing animals: immunohistochemical analysis of the expression of TGF-β and VEGF
OBJECTIVE: During the neonatal and infancy periods, some chronic liver diseases may lead to progressive hepatic fibrosis, which is a condition that can ultimately result in the loss of organ function and severe portal hypertension necessitating hepatic transplantation. In a previous report, pharmacological interventions were demonstrated to modulate hepatic

15. Increased immunohistochemical expression of YKL-40 in the spleen of patients with portal hypertension
YKL-40 has been identified as a growth factor in connective tissue cells and also a migration factor in vascular smooth muscle cells. To a large extent, the increase of serum YKL-40 is attributed to liver fibrosis and asthma. However, the relationship of the expression and clinical/prognostic significance of YKL-40 to the splenomegaly of patients with portal

16. The diameter of the originating vein determines esophageal and gastric fundic varices in portal hypertension secondary to posthepatitic cirrhosis
OBJECTIVE: The aim of this study was to determine whether and how the diameter of the vein that gives rise to the inflowing vein of the esophageal and gastric fundic varices secondary to posthepatitic cirrhosis, as measured with multidetector-row computed tomography, could predict the varices and their patterns. METHODS: A total of 106 patients with posthepa

17. Ultrasound versus biological markers in the evaluation of periportal fibrosis in human Schistosoma mansoni
In this paper, the authors review the literature and share their experience of the principal biological markers of fibrosis for the evaluation of periportal fibrosis (PPF) caused by mansoni schistosomiasis. These biological markers are compared to diagnostic ultrasound (US) scans as means of grading PPF. We also review procollagen type I and III, collagen ty

18. Schistosomal glomerulopathy and changes in the distribution of histological patterns of glomerular diseases in Bahia, Brazil
Distinct patterns of glomerular lesions, including membranoproliferative glomerulonephritis and focal segmental glomerulosclerosis, are associated with infection by Schistosoma mansoni or Schistosoma japonicum. Evidence suggests that immune complex deposition is the main mechanism underlying the different forms of schistosomal glomerulonephritis and that imm

19. Interobserver variability of ultrasound parameters in portal hypertension
The aim of this study was to assess interobserver agreement of ultrasound parameters for portal hypertension in hepatosplenic mansonic schistosomiasis. Spleen size, diameter of the portal, splenic and superior mesenteric veins and presence of thrombosis and cavernous transformation were determined by three radiologists in blinded and independent fashion in 3

20. Imaging techniques and histology in the evaluation of liver fibrosis in hepatosplenic schistosomiasis mansoni in Brazil: a comparative study
Few publications have compared ultrasound (US) to histology in diagnosing schistosomiasis-induced liver fibrosis (LF); none has used magnetic resonance (MR). The aim of this study was to evaluate schistosomal LF using these three methods. Fourteen patients with hepatosplenic schistosomiasis admitted to hospital for surgical treatment of variceal bleeding wer

21. Serum hyaluronan and collagen IV as non-invasive markers of liver fibrosis in patients from an endemic area for schistosomiasis mansoni: a field-based study in Brazil
Non-invasive markers of fibrosis have been used to diagnose liver fibrosis in a variety of diseases. Hyaluronic acid (HA) and collagen IV (C-IV) levels were measured in the sera of patients from an endemic area for schistosomiasis in Brazil to diagnose and to rank the intensity of liver fibrosis. Seventy-nine adult patients with schistosomiasis, in the age r

23. Sistemic hemodynamics (>2 years) and intrapulmonary vasodilatation before and after surgical treatment of portal hypertension due to hepatoesplenic mansonic shistosomiasis: Comparative analysis of esophagogastric devascularization with splenectomy (EGDS) and distal splenorenal shunt (DSRS) / Padrão hemodinâmico tardio (>2 anos) e vasodilatação intrapulmonar, antes e após tratamento cirúrgico da hipertensão portal secundária à forma hepatoesplênica da esquistossomose mansônica: análise comparativa entre desconexão ázigo-port
O presente estudo avaliou comparativamente o padrão hemodinâmico e a presença de vasodilatação intrapulmonar antes e após tratamento cirúrgico tardio (>2 anos) da hipertensão portal através da desconexão ázigo portal com esplenectomia (DAPE) e anastomose esplenorenal distal (AERD) na esquistossomose mansônica forma hepatoesplênica.

24. Estudo da translocação bacteriana em um modelo experimental de hipertensão porta aguda e crônica / Bacterial translocation studyin acute and chronic portal hypertension experimental model
A Hipertensão Porta (HP) é uma síndrome clínica que se manifesta com ascite, encefalopatia porto-sistêmica e hemorragia de varizes de esôfago, e estas alterações frequentemente se associam às infecções bacterianas e evoluem para o óbito. O predomínio de bactérias de origem entérica nestas infecções sugere a participação do fenômeno da tra
