1. Cardiac complications associated with the influenza viruses A subtype H7N9 or pandemic H1N1 in critically ill patients under intensive care
Abstract Background and objective: The clinical presentations and disease courses of patients hospitalized with either influenza A virus subtype H7N9 (H7N9) or 2009 pandemic H1N1 influenza virus were compared in a recent report, but associated cardiac complications remain unclear. The present retrospective study investigated whether cardiac complications in

3. A DESCRIPTIVE STUDY OF PANDEMIC INFLUENZA A(H1N1)PDM09 IN BRAZIL, 2009 - 2010
SUMMARY Influenza A viruses undergo frequent antigenic mutations and may thus cause seasonal epidemics and pandemics. The aim of this study was to recover the epidemiological history of the pandemic influenza A(H1N1)pdm09 in Brazil. A descriptive study was conducted in 2009-2010. The Brazilian Information System for reportable diseases (SINAN) was the data s

4. Pneumonia domiciliar associada a infecção pelo vírus p-H1N1 2009 em hospital terciário: frequência, características clínico-laboratoriais e aplicação de escores para predizer diagnóstico e prognóstico / Community-Acquired Pneumonia associated with p-H1N1 2009 infection in a tertiary hospital: frequency, clinical characteristics and applicability of scores to predict diagnosis and prognosis
Introdução: Em 13 de Setembro de 2009, a OMS reportou que existiam mais de 296.471 casos confirmados laboratorialmente de infecção pelo p-H1N1 2009. Ainda assim muitas questões permanecem, incluindo o papel de regras de probabilidade clínica e escores de gravidade de pneumonia adquirida na comunidade nestes pacientes. Nós descrevemos as característic

5. Imunogenicidade e segurança da vacina contra influenza A H1N1/2009 em pacientes com artrite idiopática juvenil / Immunogenicity and safety of the influenza A H1H1/2009 vaccine in juvenile idiopathic arthritis patients
Introdução: A pandemia de gripe A H1N1 em junho de 2009 resultou em elevadas taxas de hospitalização entre pacientes imunodeprimidos, incluindo pacientes com artrite idiopática juvenil (AIJ). Embora a vacinação seja uma medida eficaz contra complicações da gripe pandêmica, não há estudos na literatura sobre seus efeitos na AIJ. Objetivos: Avaliar

6. Pediatric hospital admissions from influenza A (H1N1) in Brazil: effects of the 2010 vaccination campaign
lIn 2009, the influenza A (H1N1) virus spread rapidly around the world, causing the first pandemic of the 21st Century. In 2010, there was a vaccination campaign against this new virus subtype to reduce the morbidity and mortality of the disease in some countries, including Brazil. Herein, we describe the clinical and epidemiological characteristics of patie

7. Subtype cross-reactive, infection-enhancing antibody responses to influenza A viruses.
Antibody-dependent enhancement of the uptake of influenza A virus by Fc receptor-bearing cells was analyzed by using virus strains of the three human influenza A virus subtypes, A/PR/8/34 (H1N1), A/Japan/305/57 (H2N2), and A/Port Chalmers/1/73 (H3N2). Immune sera obtained from mice following primary infection with an H1N1, H2N2, or H3N2 subtype virus neutral

8. Class I H-2d-restricted cytotoxic T lymphocytes recognize the neuraminidase glycoprotein of influenza virus subtype N1.
Class I major histocompatibility complex-restricted cytotoxic T lymphocytes (CTL) that recognize the neuraminidase (NA) glycoprotein of subtype N1 influenza A viruses have been demonstrated in BALB/c mice. Responses to NA were obtained only in protocols that use two in vivo inoculations of virus, including a recombinant vaccinia virus containing the NA of su

9. Development of subtype-specific and heterosubtypic antibodies to the influenza A virus hemagglutinin after primary infection in children.
Children undergoing primary infection with an H1N1 or H3N2 influenza A virus developed subtype-specific hemagglutination inhibition antibodies and enzyme-linked immunosorbent assay antibodies to purified hemagglutinin (HA) of the infecting virus subtype. They also developed lower titered ELISA antibodies to the noninfecting H1 or H3 HA and to H8 (an avian st

10. Hyperattenuated Recombinant Influenza A Virus Nonstructural-Protein-Encoding Vectors Induce Human Immunodeficiency Virus Type 1 Nef-Specific Systemic and Mucosal Immune Responses in Mice
We have generated recombinant influenza A viruses belonging to the H1N1 and H3N2 virus subtypes containing an insertion of the 137 C-terminal amino acid residues of the human immunodeficiency virus type 1 (HIV-1) Nef protein into the influenza A virus nonstructural-protein (NS1) reading frame. These viral vectors were found to be genetically stable and capab

11. Effect of heterosubtypic immunity on infection with attenuated influenza A virus vaccines in young children.
Resistance to infection with an influenza A virus conferred by previous infection with an influenza A virus belonging to another subtype is called heterosubtypic immunity. Heterosubtypic immunity is demonstrable in laboratory animals but is believed to be weak in humans. The present study examined whether heterosubtypic immunity from previous influenza virus

12. Type- and subtype-specific detection of influenza viruses in clinical specimens by rapid culture assay.
A rapid culture assay which allows for the simultaneous typing and subtyping of currently circulating influenza A(H1N1), A(H3N2), and B viruses in clinical specimens was developed. Pools of monoclonal antibodies (MAbs) against influenza A and B viruses and MAbs HA1-71 and HA2-76, obtained by immunizing mice with the denatured hemagglutinin subfragments HA1 a
