This study describes the case of a patient who developed symptoms of rhinoconjunctivitis on exposure to budgerigars and parrots. An IgE-mediated allergy to budgerigar, parrot and pigeon antigens was demonstrated using both in-vivo challenge tests (skin and nasal provocation tests) and in-vitro investigations (radio-allergo-sorbent test, histamine release test). The study shows that the development of nasal disease can be associated with allergy to avian antigens.

The ongoing circulation of influenza A H5N1 in the United States has raised concerns of a pandemic caused by highly pathogenic avian influenza. Although the United States has stockpiled and is prepared to produce millions of vaccine doses to address an H5N1 pandemic, currently circulating H5N1 viruses contain multiple mutations within the immunodominant head domain of hemagglutinin (HA) compared to the antigens used in stockpiled vaccines. It is unclear if these stockpiled vaccines will need to be updated to match the contemporary H5N1 strains.

Introduction: While it remains impossible to predict the timing of the next influenza pandemic, novel avian influenza A viruses continue to be considered a significant threat.
Methods: A Phase II study was conducted in healthy adults aged 18-64 years to assess the safety and immunogenicity of two intramuscular doses of pre-pandemic 2017 influenza A(H7N9) inactivated vaccine administered 21 days apart. Participants were randomized (n = 105 in each of Arms 1-3) to receive 3.

Background: Asthma, a chronic inflammatory lung disease, is one of the leading causes of disability, demands on health resources, and poor quality of life. It is necessary to identify asthma-related risk factors to reduce the presence and development of symptoms.
Objective: This study aimed to explore the association of multiple possible factors with asthma symptoms in two subpopulations, children, adolescents, and adults, in six cities in Colombia.

Background: Bird fancier's disease is a type of HP occurring due to exposure to bird's antigen. The diagnosis is quite difficult as it requires the identification of an inciting agent with findings of HRCT and lung biopsy. The exposure is usually done by history with antigen-specific IgG and/or specific inhalational challenge testing.
