BACKGROUND Acute severe ulcerative colitis (ASUC) is a complication of ulcerative colitisassociated with high levels of circulating tumor necrosis factor alpha, due to theintense inflammation and faster stool clearance of anti-tumor necrosis factordrugs. Dose-intensified infliximab treatment can be beneficial and is associatedwith lower rates of colectomy. The aim of the study was to present a case of apatient with ASUC and megacolon, treated with hydrocortisone and acceleratedscheme of infliximab that was monitored by drug trough *** SUMMARYA 22-year-old female patient diagnosed with ulcerative colitis, presented withdiarrhea, rectal bleeding, abdominal pain, vomiting, and distended *** investigation, a positive toxin for Clostridium difficile and colonic dilatationof 7 cm consistent with megacolon were observed. She was treated with oralvancomycin for pseudomembranous colitis and intravenous hydrocortisone forsevere colitis, which led to the resolution of megacolon. Due to the persistentsevere colitis symptoms, infliximab 5 mg/kg was prescribed, monitored by drugtrough level (8.8 μg/mL) and fecal calprotectin of 921 μg/g (< 30 μg/g). Based onthe low infliximab trough level after one week from the first infliximab dose, thepatient received a second infusion at week 1, consistent with the acceleratedregimen (infusions at weeks 0, 1, 2 and 6). We achieved a positive clinical andendoscopic response after 6 mo of therapy, without the need for a *** accelerated infusions can be beneficial in ASUC unresponsive to thetreatment with intravenous corticosteroids. Longitudinal studies are necessary todefine the best therapeutic drug monitoring and treatment regimen for thesepatients.

Anthropometric indicators of visceral adiposity as predictors of non-alcoholic fatty liver disease: A review

引用

World Journal of Hepatology 2018年第10期10卷 695-701页

作者： Naiade Silveira almeida Raquel rocha Helma Pinchemel Cotrim Carla Daltro Department of Sciences of Nutrition School of Nutrition Universidade Federal da Bahia Faculty of Medicine of Bahia Universidade Federal da Bahia

The objective was to critically analyze studies that evaluated the predictive capacity of indicators of visceral adiposity in non-alcoholic fatty liver disease(NAFLD). The bibliographic research was carried out using the electronic database PubMed, LILACS and SciELO, references of selected articles. Although we found few studies, they have already used several indicators of visceral adiposity as waist circumference, waist-to-hip ratio, waist-to-height ratio, Lipid accumulation product, Body Shape Index, Body Roundness Index and most them were good predictors of NAFLD. Thus, the anthropometric indicators may contribute for the diagnosis of NAFLD in a simple, low-cost and noninvasive way, allowing early therapeutic measures to prevent the evolution to non-alcoholic steatohepatitis.
