IL28B gene polymorphisms in mono- and HIV-coinfected chronic hepatitis C patients.

Introduction: Single-nucleotide polymorphisms (SNPs) associated with hepatitis C virus (HCV) clearance were identified near the IL28B gene. Coinfection by the human immunodeficiency virus (HIV) influences the course of HCV contributing to liver damage. Nevertheless, little is known about the relationship between these SNPs and HCV/HIV coinfection.

T300A genetic polymorphism: a susceptibility factor for Crohn's disease?

Context: Crohn's disease is characterized by a chronic and debilitating inflammatory disorder of the gastrointestinal tract. Several factors may contribute to its development. From extensive studies of the human genome, the polymorphism T300A of the gene ATG16L1 (autophagy-related 16-like 1) has been related to increased risk of developing this disease.

Interleukin 28B-related polymorphisms: a pathway for understanding hepatitis C virus infection?

Aim: To analyze the role of rs12979860 and rs8099917 polymorphisms in hepatitis C virus (HCV) genotype 1 infection of Brazilians.

Methods: A total of 145 adult patients diagnosed with genotype 1 chronic hepatitis C (CHC) who had completed a 48-wk regimen of pegylated-interferon α-2a or -2b plus ribavirin combination therapy were recruited from six large urban healthcare centers and 199 healthy blood donors (controls) from a single site between January 2010 and January 2012. Data on the patients' response to treatment was collected.

A straightforward genotyping of the relevant IL28B SNPs for the prediction of hepatitis C treatment outcome.

A sustained virological response is not achieved by a significant proportion of chronic hepatitis C patients treated with interferon-based regimens. Due to the associated side effects and high costs, therapy response markers have been thoroughly sought. Two Single Nucleotide Polymorphisms (SNPs), rs12979860 and rs8099917, which are located upstream from the IL28B gene, have been remarkably described to have a strong association with treatment efficacy.

Molecular panel for detection of sepsis-related microorganisms.

Introduction: Sepsis is a systemic inflammatory response related to high mortality rates in the hospital environment. Delayed etiological diagnosis and inadequate antimicrobial therapy are associated with treatment failures. Molecular tests based on polymerase chain reaction are regarded as faster and more accurate procedures than culture techniques for microbial identification, providing a higher rate of therapeutic success.

Dexamethasone compared to metoclopramide in the prophylaxis of emesis in children undergoing ambulatory surgical procedures.

Background And Objectives: Postoperative vomiting is a common and unpleasant complication. Currently, however, mathematical models, such as number necessary to treat (NNT) and relative risk reduction (RRR), have been useful in the decision of which medication to use for prophylaxis. This study aimed at verifying whether dexamethasone, as compared to metoclopramide, decreases the incidence of vomiting when intravenously administered to children anesthetized with sevoflurane for ambulatory pediatric surgeries.
