THE EVALUATION OF INFLIXIMAB TROUGH LEVEL FAVORS MAINTENANCE THERAPY OF PATIENTS WITH INFLAMMATORY BOWEL DISEASE.

Background: Crohn's disease (CD) and ulcerative colitis (UC) are chronic diseases that result from the deregulation of the mucosal immune system of the gastrointestinal tract. The use of biological therapies, including infliximab (IFX), is one of the strategies to treat both CD and UC. The IFX treatment is monitored by complementary tests, namely: fecal calprotectin (FC); C-reactive protein (CRP); and endoscopic and cross-sectional imaging.

A Systematic Review and Meta-analyses of Longitudinal Studies on Drug Treatments for Gaucher Disease.

Objective: Gaucher disease (GD) is a rare disorder linked to the absence/deficiency of glucocerebrosidase. GD can be treated by enzyme replacement therapy (ERT) and substrate reduction therapy (SRT). The aim of this systematic review (SR) is to assess the effectiveness of drugs used for GD treatment.

Cost-utility analysis of interferon-free treatments for patients with early-stage genotype 1 hepatitis C virus in Brazil.

Introduction: We conducted a cost-utility analysis of available interferon-free treatments for patients with early-stage genotype 1 chronic hepatitis C based on a Brazilian public health system perspective.

Methods: A Markov model was derived using a cohort of stage F0-F2 patients treated as recommended by the Brazilian national guidelines.

Results: Glecaprevir plus pibrentasvir was superior to all other treatments, followed by sofosbuvir plus velpatasvir.

Liver involvement in patients with Gaucher disease types I and III.

Background & Aims: Gaucher disease (GD) is a multisystemic disease. Liver involvement in GD is not well characterised and ranges from hepatomegaly to cirrhosis and hepatocellular carcinoma. describe, and assess the effect of treatment, on the hepatic phenotype of a cohort of patients with GD types I and II.

EVALUATION OF PROGRESSION OF HEPATIC FIBROSIS IN A GROUP OF PATIENTS WITH NON-ALCOHOLIC FATTY LIVER DISEASE ACCOMPANIED FOR 10 YEARS.

Background: Non-alcoholic fatty liver disease has been progressively diagnosed in the general population as a consequence of the increased prevalence of obesity and type 2 diabetes mellitus, its main risk factors. It is characterized by accumulation of fat in the hepatocytes associated with lobular inflammation and balonization, which can lead to cirrhosis and hepatocarcinoma. Thus, a characterization and follow-up of a progression of the fibrosis level of these patients becomes important, being that the transient hepatic elastography is a reliable method for this evaluation with a measure of the kapa index.

Direct antiviral therapy for treatment of hepatitis C: A real-world study from Brazil.

Introduction And Objectives: Direct antiviral agents (DAAs) including sofosbuvir (SOF), daclatasvir (DCV), simeprevir (SIM) and ombitasvir, paritaprevir and dasabuvir were introduced 2015 in Brazil for treatment of hepatitis C virus (HCV) infection. The aims of this study were to assess effectiveness and safety of HCV treatment with DAA in real-life world in a highly admixed population from Brazil.

Materials And Methods: All Brazilian reference centers for HCV treatment were invited to take part in a web-based registry, prospectively conducted by the Brazilian Society of Hepatology, to assess outcomes of HCV treatment in Brazil with DAAs.

Effects of MASP2 haplotypes and MASP-2 levels in hepatitis C-infected patients.

Mannan-binding lectin (MBL) and MBL-associated serine protease 2 (MASP-2) are components of the lectin pathway, which activate the complement system after binding to the HCV structural proteins E1 and E2. We haplotyped 11 MASP2 polymorphisms in 103 HCV patients and 205 controls and measured MASP-2 levels in 67 HCV patients and 77 controls to better understand the role of MASP-2 in hepatitis C susceptibility and disease severity according to viral genotype and fibrosis levels. The haplotype block MASP2*ARDP was associated with protection against HCV infection (OR = 0.

Neurocognitive impairment with hepatitis C and HIV co-infection in Southern Brazil.

Although cognitive impairment has been well documented in human immunodeficiency virus (HIV) and hepatitis C virus (HCV) mono-infections, research on neurocognitive effects is limited in the context of HIV/HCV co-infection. The aims of this study were to explore the interplay between HIV and HCV infections in the expression of neurocognitive impairment (NCI), and to examine the differences in test performance between HIV/HCV co-infected and HIV or HCV mono-infected patients. A total of 128 participants from Southern Brazil underwent a comprehensive neuropsychological (NP) battery comprising 18 tests.

Can FIB4 and NAFLD fibrosis scores help endocrinologists refer patients with non-alcoholic fat liver disease to a hepatologist?

Objective: The objective of this study is to evaluate the performance of mathematical models used in non-invasive diagnosis of liver fibrosis in nonalcoholic fatty liver disease (NAFLD) patients to determine when the patient needs to be referred to a hepatologist.

Subjects And Methods: Patients referred by endocrinologists to the liver outpatient departments in two hospitals in Curitiba, Brazil, over a 72-month period were analyzed. The results calculated using the APRI, FIB 4, FORNS and NAFLD Fibrosis Score non-invasive liver fibrosis assessment models were analyzed and compared with histological staging of this population.

Network meta-analysis of first- and second-generation protease inhibitors for chronic hepatitis C genotype 1: efficacy based on RVR and SVR 24.

Purpose: This study aimed to compare the efficacy among direct-acting antiviral agents (first and second-generation direct-acting antiviral agents (DAAs)) with placebo and with standard dual therapy (pegylated interferon + ribavirin (Peg-IFN + RBV)) in terms of rapid virologic response (RVR) and sustained virologic response (SVR) in chronic hepatitis C genotype 1 treatment.

Methods: We performed a systematic review of randomized controlled trials (RCTs) in MEDLINE, International Pharmaceutical Abstracts, Cochrane Library, SCIELO, and Scopus and conducted a network meta-analysis to compare the efficacy of boceprevir (BOC), daclatasvir (DCV), grazoprevir, simeprevir (SMV) and telaprevir (TVR), in treatment-naive and treatment-experienced patients.

Results: Sixteen studies encompassing 7171 patients were analysed.

Economic evaluation of treatments for chronic hepatitis B.

The aim of this study was to conduct a cost-utility study of adefovir, entecavir, interferon alpha, pegylated interferon alpha, lamivudine and tenofovir for chronic hepatitis B in the context of Brazilian Public Health Care System. A systematic review was carried out for efficacy and safety. Another review was performed to collect utility data and transition probabilities between health states.

Haplotype specific-sequencing reveals MBL2 association with asymptomatic Plasmodium falciparum infection.

Background: Mannose binding lectin (MBL) has an important role in the activation of the complement system and opsonization of pathogenic microorganisms. Frequent polymorphisms found in the MBL2 gene affect the concentration and functionality of the protein and are associated with enhanced susceptibility to severe malaria in African children. Most MBL2 typing strategies were designed to the analysis of selected variants, the significance of whole haplotypes is poorly known.

[The sustained response rates for chronic hepatitis C patients undergoing therapy with the several interferons and ribavarins supplied by Brazilians Health Ministry is comparable to those reported in the literature].

Background: The sustained response rates of chronic hepatitis C therapy to interferons alpha 2A and 2B associated to ribavirin are described as approximately 40%. Nevertheless, studies on the sustained response rates in a setting of frequent changes of type of interferon as well as of supplies of interferons and ribavirin are lacking.

Aims: To evaluate the prevalence of sustained response and to determine the predictors of response to chronic hepatitis C therapy, in a cohort of outpatients at Curitiba, PR, south Brazil, in a setting of heterogeneous therapy regarding type and supply of the medications.
