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…)

Definitions of anaphylaxis vary considerably, impeding the comparison of different clinical studies. Different definitions of anaphylaxis have been developed as clinical descriptions of severe allergic reactions, different authors emphasizing different symptoms.
The author aimed to develop a simple clinical grading system and definition for anaphylaxis using clinical data. He retrospectively analyzed 1149 case records (median age 29 years) with systemic allergic reactions (30% venom allergy, 22% iatrogenic allergy, 18% food allergy) from an emergency department in Australia.

Extrinsic allergic alveolitis (synonym: hypersensitivity pneumonitis) describes an interstitial and bronchioloalveolar disease of the lungs caused by an immune mediated hypersensitivity response. It is associated with repeated exposure to a variety of inhaled organic dusts and reactive chemicals (allergy chemical), but only a proportion of exposed subjects become affected. Notable examples are farmers’ lung (due to actinomycetes contaminating farm produce) and bird fanciers’ lung (due to secreted avian antigens). The disease has considerable potential as a model of allergic lung disease, since the populations at risk can often be identified precisely, the relevant antigens can be purified, and the clinical and immunologic consequences of antigen exposure can be examined.

Allergies can be defined as inappropriate immune system reactions to a foreign substance entering body. Allergies are kind of diseases of immune system works to react to certain substances called allergens. Normally when a person is exposed to a harmless substance such as pollen, causes the body natural immune system to respond as if the substance is harmful. Some allergies are inherited from their parents or can be gained in environmental exposure. There are several common allergen exposures like mold, animal dander, pollen, dust mites, and many others.

The cross-sensitivity between aspirin and Non Steroidal Anti Inflammatory Drugs in patients who manifest pseudo-allergic reactions to aspirin affecting the respiratory tract occurs because Non Steroidal Anti Inflammatory Drugs, like aspirin, inhibit COX-1, so that arachidonic acid metabolism is diverted towards the 5-lipoxygenase pathway, with resulting increased production of cysteinyl leukotrienes, which mediate the appearance of symptoms such as allergic rhinitis and asthma. Selective inhibitors of Cyclo-Oxygenase-2 or COX-2 were developed primarily to reduce the incidence of adverse events affecting the gastrointestinal tract symptoms, but the possibility that these agents might be less likely to result in other varieties of adverse reaction dependent on COX-1 inhibition has attracted interest. This review examined the evidence for their greater safety in this respect. (more…)
