ABSTRACT BACKGROUND: Treatment for inflammatory bowel disease (IBD) includes a variety of immunosuppressants and biological agents, which increase the risk of infections due to altered cellular and humoral immunity. Prevention of these infections can be done through vaccination, however, patients with IBD are usually under-immunized. OBJECTIVE: Analyze the immunization status of patients with IBD and confront it with the current recommendations to verify if the immunization guidelines are being...

ABSTRACT BACKGROUND: Autoimmune hepatitis (AIH) is a rare chronic inflammatory liver disease associated with a loss of immunological tolerance to self-antigens. Susceptibility to AIH is partially determined by the presence of genes related to human leukocyte antigen (HLA), mainly allelic variants of DRB1. OBJECTIVE: The purpose of this study was to investigate the frequencies of the polymorphisms in HLA-DRB1 gene in children and adolescents with type 1 AIH and type 1 AIH overlap syndrome with...

ABSTRACT BACKGROUND: The diagnosis of eosinophilic esophagitis (EoE) is performed by the detection of 15 or more eosinophils per field in an esophageal biopsy sample, but the endoscopic findings alone are not validated for a diagnosis of the disease. OBJECTIVE: To evaluate the association between the endoscopic findings and histopathological diagnosis in patients with suspected EoE in endoscopy. METHODS: A retrospective study of 24 patients with suspicion of EoE during endoscopy was held. The...

ABSTRACT BACKGROUND: Gastric cancer is known as the fourth most common cancer. Current treatments for cancer have damaged the sensitive tissues of the healthy body, and in many cases, cancer will be recurrent. Therefore, need for treatments that are more effective is well felt. Researchers have recently shifted their attention towards antipsychotic dopamine antagonists to treat cancer. The anticancer activities of aripiprazole remain unknown. OBJECTIVE: This study aimed to evaluate the efficacy...

ABSTRACT BACKGROUND: Internal hernia (IH) following laparoscopic Roux-en-Y gastric bypass (LRYGB) is a major complication that challenges the surgeon due to its non-specific presentation and necessity of early repair. Delayed diagnosis and surgical intervention of IH might lead to increased morbidity of patients and impairments in their quality of life. OBJECTIVE: To evaluate the predictive factors for early diagnosis and surgical repair of IH after LRYGB. METHODS: This study analyzed 38 patients...

ABSTRACT BACKGROUND: Liver transplantation (LTx) is the primary and definitive treatment of acute or chronic cases of advanced or end-stage liver disease. Few studies have assessed the actual cost of LTx categorized by hospital unit. OBJECTIVE: To evaluate the cost of LTx categorized by unit specialty within a referral center in southern Brazil. METHODS: We retrospectively reviewed the medical records of 109 patients undergoing LTx between April 2013 and December 2014. Data were collected on...

ABSTRACT BACKGROUND: Considering the high incidence of colorectal cancer (CRC) related deaths, many studies have investigated variables that can affect survival, with the aim of prolonging survival. The nutritional status can also be predict survival in patients with CRC. OBJECTIVE: The aim of the present study was to evaluate if BMI, %FAT, PhA, PG-SGA, adiponectin levels, and vitamin D levels are relevant to the characterization and differentiation of patients with advanced CRC and patients...

ABSTRACT BACKGROUND: Abdominal tuberculosis is an increasing problem in developing world. OBJECTIVE: The objective of the study was to describe the clinical presentations, drug resistance pattern and treatment outcomes of abdominal tuberculosis in Western India. METHODS: All the cases of abdominal tuberculosis from May 2014 to April 2017, diagnosed on the basis of clinical profile and gross morphological findings at endoscopy, imaging, followed by histology and/or GeneXpert and MGIT culture...

ABSTRACT BACKGROUND: Nowadays, pharmacological treatment of non-alcoholic fatty liver disease (NAFLD) is still limited and it is based on the treatment of conditions associated comorbities. Oxidative stress and insulin resistance are the mechanisms that seem to be mostly involved in its pathogenesis. OBJECTIVE: To evaluate the efficacy of N-acetylcysteine (NAC) in combination with metformin (MTF) and/or ursodeoxycholic acid (UDCA) for treatment of non-alcoholic steatohepatitis (NASH). METHODS:...

ABSTRACT BACKGROUND: Colorectal cancer is one of the most prevalent pathologies. Its prognosis is linked to the early detection and treatment. Currently diagnosis is performed by histological analysis from polyp biopsies, followed by morphological classification. Kudo’s pit pattern classification is frequently used for the differentiation of neoplastic colorectal lesions using hematoxylin-eosin stained samples. Few articles have reported this classification with image software processing, using...

ABSTRACT BACKGROUND: 13C-urea breath test (UBT) is the gold-standard, noninvasive method for H. pylori diagnosis. However, there is no uniform standardization of the test. This situation can be unpractical for laboratories running with two or more devices. OBJECTIVE: To perform a prospective comparison validation study of UBT employing one validated protocol for two different devices: BreathID Hp Lab System® (Exalenz Bioscience Ltd, Israel), here called device A and IRIS-Doc2® (Wagner Analysen-Technik,...

ABSTRACT BACKGROUND: Gastroesophageal reflux disease (GERD) is one of the most prevalent gastrointestinal diseases. GERD generates significant impairment in patients’ quality of life and it is associated to relevant medical resources utilization. A better understanding of GERD pathophysiology in the past five decades has favored the evolution of therapeutic strategies from non-drug interventions and antacids to more efficacious and safer alternatives. OBJECTIVE: To summarize data about the historical...

ABSTRACT Liver and biliary tract diseases are common causes of morbidity and mortality worldwide. Invasive procedures are usually performed in those patients with hepatobiliary diseases for both diagnostic and therapeutic purposes. Defining proper indications and restraints of commonly used techniques is crucial for proper patient selection, maximizing positive results and limiting complications. In 2018, the Brazilian Society of Hepatology (SBH) in cooperation with the Brazilian Society of Interventional...

ABSTRACT New data concerning the management of autoimmune liver diseases have emerged since the last single-topic meeting sponsored by the Brazilian Society of Hepatology to draw recommendations about the diagnosis and treatment of autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC), overlap syndromes of AIH, PBC and PSC and specific complications and topics concerning AIH and cholestatic liver diseases. This manuscript updates those previous recommendations...
