Arq. gastroenterol; 53 (4), 2016
ABSTRACT Background Celiac disease is a permanent intolerance induced by gluten, which is expressed by T-cell mediated enteropathy, and has a high prevalence in the general population. There is evidence of a strong genetic predisposition to celiac disease. Objective To determine the prevalence of genet...

Frequency of the mdr1 gene polymorphism rs1045642 (c3435t) in hcv-hiv co-infected patients

Arq. gastroenterol; 53 (4), 2016
ABSTRACT Background Due to the high prevalence of co-infection by hepatitis C virus (HCV) and human immunodeficiency virus (HIV) and the severity of these infections, the understanding of the biological mechanisms involved in these processes, including viral behavior and host genetic profile, is of grea...

Association of PRKAA1 gene polymorphisms with chronic hepatitis B virus infection in Chinese Han population

Braz. j. infect. dis; 20 (6), 2016
ABSTRACT Objective: Studies have indicated that AMPK play critical roles in the regulation of innate immunity and inflammatory responses. However, the role of the polymorphisms of PRKAA1 gene in immune-response to infectious organisms remains unknown. To evaluate the potential role of PRKAA1/AMPKα1...

Local circulating clones of Staphylococcus aureus in Ecuador

Braz. j. infect. dis; 20 (6), 2016
ABSTRACT The spread of pandemic Staphylococcus aureus clones, mainly methicillin-resistant S. aureus (MRSA), must be kept under surveillance to assemble an accurate, local epidemiological analysis. In Ecuador, the prevalence of the USA300 Latin American variant clone (USA300-LV) is well known; however, t...
