Human Rhinovirus (HRV) classification is an evolving process. New genotypes have been described within HRV-A and HRV-C species, but only one has been accepted related to HRV-B. From 2003 to 2010, a total of 3987 nasopharyngeal aspirate samples were taken from pediatric patients admitted to the Severo Ochoa Hospital in Madrid (Spain). After viral analysis, 949 (23.8%) tested positive to HRV. A r...
Concerning my hypothesis of efficacy of magnesium throat lozenges as a rapid acting rescue treatment for asthma as I described in my 2006 article [1] published in this journal, I only worked with adults that had allergy-induced asthma. I did not work with infants or children. There is an important difference between the asthma of adults and that of the pediatric age group. Adult asthma is belie...
Natural rhinovirus infection in adults is usually associated with an afebrile coryzal syndrome (Hobson and Schild, 1960; Hamre and Procknow, 1961 ; Reilly et al., 1962 ; Forsyth et al., 1963), and, depending on the population studied, rhinoviruses as a group are associated with 8 to 25 % of minor upper respiratory illnesses in adults and from 5 to 20% of such illnesses in children (Tyrrell and ...
Rhinoviruses are important respiratory pathogens implicated in asthma exacerbations. The mechanisms by which rhinoviruses trigger inflammatory responses in the lower airway are poorly understood, in particular their ability to infect the lower airway. Bronchial inflammatory cell (lymphocyte and eosinophil) recruitment has been demonstrated. IL-8 is a potent proinflammatory chemokine that is che...
BACKGROUND The contribution of viral respiratory infections during infancy to the development of subsequent wheezing and/or allergic diseases in early childhood is not established. OBJECTIVE To evaluate these relationships prospectively from birth to 3 years of age in 285 children genetically at high risk for developing allergic respiratory diseases. METHODS By using nasal lavage, the relat...
Rhinovirus infections have afflicted humanity since the dawn of civilization, and are difficult to treat even with modern medicine. Throughout the ages many remedies have been used for the common cold, often caused by the rhinovirus. Recent research points to a flavanol anti-oxidant, quercetin, as having therapeutic properties. Quercetin has been shown to reduce viral internalization and replic...
Dans, P. E. (National Institute of Allergy and Infectious Diseases, Bethesda, Md.), B. R. Forsyth, and R. M. Chanock. Density of infectious virus and complement-fixing antigens of two rhinovirus strains. J. Bacteriol. 91:1605-1611. 1966.-Two rhinovirus serotypes (echovirus 28 and HGP) and poliovirus type 1 were banded by isopycnic centrifugation in cesium chloride. The rhinovirus virions had a ...
Rhinorrhea is a prominent symptom of the common cold. Although increases in vascular permeability and serous cell secretion have been demonstrated in human nasal mucus during active rhinovirus infections, changes in mucin constituents have not been quantified. Nonallergic ( n= 48) and asymptomatic allergic rhinitis ( n = 32) subjects were inoculated with rhinovirus type hanks before the spring ...
BACKGROUND COPD exacerbations are associated with neutrophilic airway inflammation. Adhesion molecules on the surface of neutrophils may play a key role in their movement from blood to the airways. We analysed adhesion molecule expression on blood and sputum neutrophils from COPD subjects and non-obstructed smokers during experimental rhinovirus infections. METHODS Blood and sputum were colle...
