Toll-like receptors (TLRs) act as receptors for numerous stimuli of immune cells, including bacterial cell wall constituents (lipopolysaccharide [LPS] from Gram-negative bacteria and lipopeptides from Gram-positive species), plasma proteins and extracellular matrix breakdown products. TLR2 and TLR4 bind lipopeptide and LPS respectively, mediating responses of alveolar macrophages and other immune cells to bacterial infection in the lungs. Exposure of lungs to LPS leads to pro-inflammatory responses of a number of cell types, including airway smooth muscle, which secretes a number of cytokines involved in leucocyte recruitment and the Th2 polarization of immune responses. Human airway smooth muscle cells were cultured with LPS in the absence and presence of peripheral blood mononuclear cells to determine direct and leucocyte-dependent TLR-mediated responses. (more…)

In the UK, Europe and the USA, montelukast is licensed for once-daily oral administration in adults and is also available as a cherry flavored pink tablet or as granules for use in children over the age of 6 months. Zafirlukast is licensed for use in individuals over 12 years of age (Fig above). In some countries such as Japan, another leukotriene receptor antagonists (LTRA), pranlukast, is available for use. In the USA, zileuton is licensed for use in those over 12 years of age (Table below). (more…)

Allergic rhinitis is a very common problem associated with poor quality of life, reductions in social and work activities and poor interpersonal relationships. The main goal of the management of allergic rhinitis is to improve the quality of life. Immunotherapy is a specific therapy for allergic rhinitis and several reports have documented the safety and efficacy of this treatment . Safety has been a key issue in immunotherapy and various modalities are being investigated to make allergy immunotherapy more tolerable and safe to administer. (more…)

IgE plays an important role in allergic asthma. Reducing IgE in the airway mucosa should reduce airway inflammation. Omalizumab has significant anti-inflammatory effect and reduces serum and airway IgE, but IgE or eosinophils may not be causally linked to airway bronchial hyperresponsiveness to methacholine in mild to moderate asthma.

Asthma and allergic diseases are common in both children and adults. Their development depends on an interaction between asthma genetic and asthma environmental risk factors. Genetic manipulation in multi factorial diseases such as asthma is not feasible in the foreseeable future. However, theoretically, environmental exposures can be controlled in an attempt to stem the rising prevalence of these diseases (primary prevention). Environmental exposures may also influence the frequency of symptoms and the requirement for medication in those with established disease. (more…)

The increasing prevalence of allergic disease in the Western world has led to the concept of the ‘allergic march’ to describe the evolving spectrum of disease that often begins in childhood. The use of allergen immunotherapy in children has the potential of altering the natural course of allergic disease. However, concerns regarding the safety of using this treatment in children are an obstacle to attenuating the allergic march. The study of Di Rienzo and colleagues reviews the safety of Sublingual Immunotherapy in children between the ages of 3 and 5 years. (more…)
