Genome analysis of yellow fever virus of the ongoing outbreak in Brazil reveals polymorphisms

Mem. Inst. Oswaldo Cruz; 112 (6), 2017
The current yellow fever outbreak in Brazil is the most severe one in the country in recent times. It has rapidly spread to areas where YF virus (YFV) activity has not been observed for more than 70 years and vaccine coverage is almost null. Here, we sequenced the whole YFV genome of two naturally infect...

Curing Chronic Hepatitis C: A Cost Comparison of the Combination Simeprevir Plus Sofosbuvir vs. Protease-Inhibitor-Based Triple Therapy

Ann. hepatol; 16 (3), 2017
ABSTRACT Introduction. Interferon-free, multi-direct acting antiviral (DAA) therapy for chronic hepatitis C virus (HCV) infection is highly effective and well tolerated, but costly. To gain perspective on the evolving economics of HCV therapy, we compared the cost per cure of a multi-DAA regimen with th...

Associations of Cerebrovascular Metabolism Genotypes With Neuropsychiatric Symptoms and Age at Onset of Alzheimer's Disease Dementia

Objective: To study associations of cerebrovascular metabolism genotypes and haplotypes with age at Alzheimer’s disease dementia (AD) onset and with neuropsychiatric symptoms according to each dementia stage. Methods: Consecutive outpatients with late-onset AD were assessed for age at dementia ons...

Type 2 diabetes-associated genetic variants of FTO, LEPR, PPARg, and TCF7L2 in gestational diabetes in a Brazilian population

ABSTRACT Objective Gestational diabetes mellitus (GDM) is a metabolic disorder that shares pathophysiologic features with type 2 diabetes mellitus. The aim of this study was to investigate the association of the polymorphisms fat mass and obesity-associated (FTO) rs1421085, leptin receptor (LEPR) rs113...

Papilomatosis respiratoria recurrente en paciente pediátrico: reporte de un caso

Rev. chil. pediatr; 88 (3), 2017
La variabilidad genética relacionada al sistema inmune del huésped ha sido propuesta como uno de los factores más influyentes en el desarrollo de enfermedades causadas por HPV. Caso clínico: Reportamos el caso de un niño de 5 años en cuyo estudio por disfonía crónica se encuentra papilomatosis la...

Ampliação do tempo de tratamento HCV - genótipo 3 com cirrose, para 24 semanas

CONTEXTO: A Organização Mundial da Saúde reconhece a epidemia de hepatites virais como um problema de saúde pública mundial. Vários esforços estão sendo realizados ao redor do planeta para promover estratégias e políticas de prevenção e controle das hepatites virais. Estima-se que a infecçã...

CYP2B6 516 G>T polymorphism and side effects of the central nervous system in HIV-positive individuals under Efavirenz treatment: Study of a sample from southern Brazil

An. acad. bras. ciênc; 89 (1,supl), 2017
ABSTRACT This study aimed to identify the 516 G>T polymorphism of the CYP2B6 gene and evaluate its influence on central nervous system (CNS) side effect development in HIV-positive individuals undergoing Efavirenz (EFV) treatment in a population from southern Brazil. Additionally, we performed a surve...

Polymorphisms in genes TLR1, 2 and 4 are associated with differential cytokine and chemokine serum production in patients with leprosy

Mem. Inst. Oswaldo Cruz; 112 (4), 2017
BACKGROUND Leprosy or hansen’s disease is a spectral disease whose clinical forms mostly depends on host’s immune and genetic factors. Different Toll-like receptors (TLR) variants have been described associated with leprosy, but with some lack of replication across different populations. OB...

Association of NR1I2 gene polymorphisms and time of progression to AIDS

Mem. Inst. Oswaldo Cruz; 112 (4), 2017
BACKGROUND The time of progression towards AIDS can vary greatly among seropositive patients, and may be associated with host genetic variation. The NR1I2 (PXR) gene, a ligand-activated transcription factor, regulates the transcription immune pathway genes and can therefore be targets of viral replicati...
