AIM: To evaluate the effectiveness and safety of oral N-acetyl-L-cysteine (NAC) co-administration with mesalamine in ulcerative colitis (UC) patients. METHODS: Thirty seven patients with mild to moderate UC were randomized to receive a four-wk course of oral mesalamine (2.4 g/d) plus N-acetyl-L-cysteine (0.8 g/d) (group A) or mesalamine plus placebo (group B). Patients were monitored using the Modified Truelove-Witts Severity Index (MTWSI). The primary endpoint was clinical remission (MTWSI ≤ 2) at 4 wk. Secondary endpoints were clinical response (defined as a reduction from baseline in the MTWSI of ≥ 2 points) and drug safety. The serum TNF-α, interleukin-6, interleukin-8 and MCP-1 were evaluated at baseline and at 4 wk of treatment. RESULTS: Analysis per-protocol criteria showed clinical remission rates of 63% and 50% after 4 wk treatment with mesalamine plus N-acetyl-L-cysteine (group A) and mesalamine plus placebo (group B) respectively (OR = 1.71; 95% CI: 0.46 to 6.36; P = 0.19; NNT = 7.7). Analysis of variance (ANOVA) of data indicated a significant reduction of MTWSI in group A (P = 0.046) with respect to basal condition without significant changes in the group B (P = 0.735) during treatment. Clinical responses were 66% (group A) vs 44% (group B) after 4 wk of treatment (OR = 2.5; 95% CI: 0.64 to 9.65; P = 0.11; NNT = 4.5). Clinical improvement in group A correlated with a decrease of IL-8 and MCP-1. Rates of adverse events did not differ significantly between both groups. CONCLUSION: In group A (oral NAC combined with mesalamine) contrarily to group B (mesalamine alone), the clinical improvement correlates with a decrease of chemokines such as MCP-1 and IL-8. NAC addition not produced any side effects.

Biliary cystadenoma

World Journal of Gastroenterology 2009年第28期15卷 3573-3575页

The diagnosis of cystadenoma is rare, even more so when located in the extrahepatic bile duct. Unspecific clinical signs may lead this pathology to be misdiagnosed. The need for pathological anatomy in order to distinguish cystadenomas from simple biliary cysts is crucial. The most usual treatment nowadays is resection of the bile duct, together with cholecystectomy and Roux-en-Y reconstruction.

A half century (1961-2011) of applying microsurgery to experimental liver research

引用

World Journal of Hepatology 2012年第7期4卷 199-208页

作者： Maria-Angeles Aller Natalia Arias Isabel prieto Salvador Agudo Carlos Gilsanz Laureano Lorente Jorge-luis Arias Jaime Arias Surgery I Department School of Medicine Complutense University of Madrid 28040 Madrid Spain Neurosciences Lab Psychobiology Department School of Psychology University of Oviedo 33003 Oviedo Spain Surgery Department La Paz Hospital School of Medicine Autonomous University of Madrid 28049 Madrid Spain General Surgery Unit Sudeste Hospital Arganda del Rey 28500 Madrid Spain

The development of microsurgery has been dependent on experimental animals. Microsurgery could be a very valuable technique to improve experimental models of liver diseases. Microdissection and microsutures are the two main microsurgical techniques that can be considered for classifying the experimental models developed for liver research in the rat. Partial portal vein ligation, extrahepatic cholestasis and hepatectomies are all models based on microdissection. On the other hand, in portacaval shunts, orthotopic liver transplantation and partial heterotopic liver transplantation, the microsuture techniques stand out. By reducing surgical complications, these microsurgical techniques allow for improving the resulting experimental models. If good experimental models for liver research are successfully developed, the results obtained from their study might be particularly useful in patients with liver disease. Therefore experimental liver microsurgery could be an invaluable way to translate laboratory data on liver research into new clinical diagnostic and therapeutic strategies.

Gut Lymphangiopathy: Adding Fuel to the Fire in Chronic Liver Disease

Advances in Bioscience and Biotechnology 2019年第10期10卷 305-319页

The splanchnic inflammation inchronic liver disease increases intestinal angiogenesis. In the current study our aim was demonstrating that the small bowel lymphangiogenesis is associated with angiogenesis in chronic cholestasis in the rat. A stereological study of the lymphatic microcirculation in the small intestine was performed in cholestatic rats. Portal enteropathy in cholestasis increases lymphatic microvessels in the mucosa and submucosa layers. Thus, the lymphatic microvessel volume fraction was superior (p < 0.001) in the mucosa (0.16 ± 0.01) and submucosa (0.16 ± 0.01), in regard to the muscle layer 0.015 ± 0.01. The lymphatic microvessel length density was higher in the mucosa (76.89 ± 2.86 mm-2;p -2;p < 0.01), in relationship to the muscle layer (5.04 ± 2.92 mm-2). These alterations predominate in the duodenum (volume fraction: 0.10 ± 0.01 and length density: 33.55 ± 5.98 mm-2) and ileum (volume fraction: 0.16 ± 0.01 and length density: 38.62 ± 6.07 mm-2). This study demonstrates the predominance of an increased lymphangiogenic response in both end sides of the small bowel associated with chronic liver disease. Since the porto-systemic venous collateral circulation in the chronic liver insufficiency is developed in the ends of the gastrointestinal tract, the excessive duodeno-ileal lymphangiogenesis could suggest the development of amesenteric-systemic lymphatic bypass in the chronic portal hypertension.

Portal hypertension-related inflammatory phenotypes: From a vitelline and amniotic point of view

Advances in Bioscience and Biotechnology 2012年第7期3卷 881-899页

Prehepatic portal hypertension induces a splanchnic low-grade inflammatory response that could switch to high-grade inflammation with the development of severe and life-threatening complications when associated with chronic liver disease. The extraembryonic origin of the portal system maybe determines the regression to an extraembryonic phenotype, i.e., vitellogenic and amniotic, during the evolution of both types of portal hypertension. Thus, prehepatic portal hypertension, or compensated hypertension by portal vein ligation in the rat, is associated with molecular mechanisms related to vitellogenesis, where hepatic steatosis and splanchnic angiogenesis stand out. In turn, extrahepatic cholestasis in the rat induces intrahepatic portal hypertension, or decompensated hypertension, with ascites and hepatorenal syndrome. The splanchnic interstitium, the mesenteric lymphatic system, and the peritoneal mesothelium seem to create an inflammatory pathway that could have a key pathophysiological relevance in the production of ascites. The hypothetical comparison between the ascitic and the amniotic fluid also allows for translational investigation. The induced regression of the splanchnic system to extraembryonic functions by portal hypertension highlights the great relevance of the extraem-bryonic structures even during postnatal life.
