Heterologous Immune Responses to Influenza Vaccine in Kidney Transplant Recipients.

Autor(es): Kumar, D; Ferreira, V H; Campbell, P; Hoschler, K; Humar, A
Fonte: Am J Transplant;17(1): 281-286, 2017 Jan.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27402204
Resumo: Influenza vaccine is known to have suboptimal immunogenicity in transplant recipients. Despite this, influenza vaccine may have the added benefit of inducing a cross-reactive immune response to viral strains not found in the vaccine. This is termed "heterologous immunity" and has not been assessed previously in transplant patients. Pre- and postvaccination sera from kidney transplant recipients (n = 60) immunized with the 2012-2013 adjuvanted or nonadjuvanted influenza vaccine underwent tes (mais)

Reassortment of high-yield influenza viruses in vero cells and safety assessment as candidate vaccine strains.

Autor(es): Zhou, Jian; Yang, Fan; Yang, Jinghui; Ma, Lei; Cun, Yina; Song, Shaohui; Liao, Guoyang
Fonte: Hum Vaccin Immunother;13(1): 111-116, 2017 Jan 02.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27648636
Resumo: Vaccination is the practiced and accessible measure for preventing influenza infection. Because chicken embryos used for vaccine production have various insufficiencies, more efficient methods are needed. African green monkey kidney (Vero) cells are recommended by the World Health Organization (WHO) as a safe substitute for influenza vaccine production for humans. However, the influenza virus usually had low-yield in Vero cells, which limits the usage of Vero cellular vaccines. This study u (mais)

Sociocultural determinants of anticipated acceptance of pandemic influenza vaccine in Pune, India: a community survey using mixed-methods.

Autor(es): Sundaram, Neisha; Schaetti, Christian; Grize, Leticia; Purohit, Vidula; Joseph, Saju; Schindler, Christian; Kudale, Abhay; Weiss, Mitchell G
Fonte: Int J Public Health;62(1): 103-115, 2017 Jan.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27658812
Resumo: OBJECTIVES: To investigate community priority and determinants of pandemic influenza vaccine acceptance in Pune, India. Community willingness to accept vaccines is often neglected in pandemic preparedness. Despite an acknowledged need, few such studies have been done in lower income countries. METHODS: A cross-sectional, mixed-methods study used semi-structured explanatory model interviews to assess anticipated acceptance of nasal and injectable vaccines at different prices among 436 urban (mais)

Construction of a recombinant duck enteritis virus vaccine expressing hemagglutinin of H9N2 avian influenza virus and evaluation of its efficacy in ducks.

Autor(es): Sun, Ying; Yang, Chenghuai; Li, Junping; Li, Ling; Cao, Minghui; Li, Qihong; Li, Huijiao
Fonte: Arch Virol;162(1): 171-179, 2017 Jan.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27709401
Resumo: H9 subtype avian influenza viruses (AIVs) remain a significant burden in the poultry industry and are considered to be one of the most likely causes of any new influenza pandemic in humans. As ducks play an important role in the maintenance of H9 viruses in nature, successful control of the spread of H9 AIVs in ducks will have significant beneficial effects on public health. Duck enteritis virus (DEV) may be a promising candidate viral vector for aquatic poultry vaccination. In this study, (mais)

Successful use of oseltamivir prophylaxis in managing a nosocomial outbreak of influenza A in a hematology and allogeneic stem cell transplant unit.

Fonte: Asia Pac J Clin Oncol;13(1): 37-43, 2017 Feb.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27730741
Resumo: AIM: To describe a nosocomial outbreak of H1N1 influenza A in an inpatient hematology and allogeneic stem cell transplant unit and outcomes of universal oseltamivir prophylaxis. METHODS: Medical records of all patients admitted to the unit were reviewed to define the nosocomial outbreak, commencing 1 week prior to the index case until 4 weeks following institution of oseltamivir prophylaxis. Timelines for clinical symptoms, viral spread, management, patient outcomes and follow up testing we (mais)

Immunogenicity of trivalent influenza vaccine in patients with lung cancer undergoing anticancer chemotherapy.

Autor(es): Nakashima, Kei; Aoshima, Masahiro; Ohfuji, Satoko; Suzuki, Kanzo; Katsurada, Masahiro; Katsurada, Naoko; Misawa, Masafumi; Otsuka, Yoshihito; Kondo, Kyoko; Hirota, Yoshio
Fonte: Hum Vaccin Immunother;13(3): 543-550, 2017 Mar 04.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27820665
Resumo: Lung cancer is a leading cause of cancer-related death, and patients with lung cancer are a priority group for influenza vaccination. However, few studies have assessed the immunogenicity of the influenza vaccine in these patients. Here, we performed a prospective study to evaluate the immunogenicity of the influenza vaccine in patients with lung cancer undergoing anticancer chemotherapy. Twenty-five patients with lung cancer undergoing anticancer chemotherapy and 26 patients with chronic o (mais)

Estimating vaccine effectiveness in preventing laboratory-confirmed influenza in outpatient settings in South Africa, 2015.

Autor(es): McAnerney, Johanna M; Walaza, Sibongile; Tempia, Stefano; Blumberg, Lucille; Treurnicht, Florette K; Madhi, Shabir A; Valley-Omar, Ziyaad; Cohen, Cheryl
Fonte: Influenza Other Respir Viruses;11(2): 177-181, 2017 Mar.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27865064
Resumo: Trivalent seasonal influenza vaccine effectiveness during the 2015 season in South Africa was assessed using a test-negative case control study design. Influenza A(H1N1)pdm09 was the dominant circulating strain. Overall influenza vaccine coverage was 3.2% (29/899). The vaccine effectiveness estimate, against any influenza virus infection, adjusted for age, underlying conditions and timing within season was 46.2% (95% CI: -23.5 to 76.5), and 53.6% (95% CI: -62.6 to 80.3) against influenza A(H1N1)pdm09.

Association Between Pandemic Influenza A(H1N1) Vaccination in Pregnancy and Early Childhood Morbidity in Offspring.

Autor(es): Hviid, Anders; Svanström, Henrik; Mølgaard-Nielsen, Ditte; Lambach, Philipp
Fonte: JAMA Pediatr;171(3): 239-248, 2017 Mar 01.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27893898
Resumo: Importance: Several studies investigating potential adverse effects of the pandemic A(H1N1) vaccine have supported that influenza A(H1N1) vaccination does not increase the risk for major pregnancy and birth adverse outcomes, but little is known about possible adverse effects in offspring of A(H1N1)-vaccinated mothers beyond the perinatal period and into early childhood. Objective: To evaluate whether pandemic influenza A(H1N1) vaccination in pregnancy increases the risk for early childhood (mais)

Protection against Streptococcus pneumoniae Invasive Pathogenesis by a Protein-Based Vaccine Is Achieved by Suppression of Nasopharyngeal Bacterial Density during Influenza A Virus Coinfection.

Autor(es): Khan, M Nadeem; Xu, Qingfu; Pichichero, Michael E
Fonte: Infect Immun;85(2)2017 Feb.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27895132
Resumo: An increase in Streptococcus pneumoniae nasopharynx (NP) colonization density during a viral coinfection initiates pathogenesis. To mimic natural S. pneumoniae pathogenesis, we commensally colonized the NPs of adult C57BL/6 mice with S. pneumoniae serotype (ST) 6A or 8 and then coinfected them with mouse-adapted H1N1 influenza A virus (PR/8/34). S. pneumoniae established effective commensal colonization, and influenza virus coinfection caused S. pneumoniae NP density to increase, resulting (mais)

Investigational hemagglutinin-targeted influenza virus inhibitors.

Autor(es): Zeng, Li-Yan; Yang, Jie; Liu, Shuwen
Fonte: Expert Opin Investig Drugs;26(1): 63-73, 2017 Jan.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27918208
Resumo: INTRODUCTION: Seasonal influenza and pandemic outbreaks typically result in high mortality and morbidity associated with severe economic burdens. Vaccines and anti-influenza drugs have made great contributions to control the infection. However, antigenic drifts and shifts allow influenza viruses to easily escape immune neutralization and antiviral drug activity. Hemagglutinin (HA)is an important envelope protein for the entry of influenza viruses into host cells, thus, HA-targeted agents ma (mais)
