Eliminating them from homes is impossible, but with some precautions the impact is reduced. Beware those who are allergic to dust may be allergic to crustaceans and molluscs
Dust mite allergy has no season, but with autumn and winter it can become more annoying because we spend more time indoors and indoors, where there are often watertight frames and windows and little air exchange: in practice, the ideal conditions for the proliferation of these tiny arthropods, relatives of spiders, which do not pinch or they bite, but they make life impossible for those who do not tolerate them. Inhaling mite allergens for allergy sufferers means having watery, red, itchy eyes, a runny nose, a sore throat, even skin eczema.
Learn more about the allergy
Living with these pets is not easy and eliminating them from homes is practically impossible, so to learn more about the allergy and above all learn to deal with it. The SOS Acari campaign, sponsored by the Respiriamo Insieme association, has just started: on the sosacari.it site you can find answers to the most frequently asked questions and, for example, find out that up to 15% of those allergic to mites also react to crustaceans and molluscs, due to similarities between proteins present in different species. Not automatic, but for some people eating shrimp or mussels can become a problem; On the other hand, physical activity is not risky, especially if it is practiced outdoors or in any case avoiding gyms where there is too much dust.
Physical activity
Movement in itself does not worsen the symptoms of allergy and is not contraindicated, with some precautions, not even in the case of allergic asthma for which dust mites are the major contributing factor.isc
hio, so much so that among asthmatic adults 50-85% do not tolerate mites, among children it reaches 90%. Almost all patients with asthma and mite allergy then have rhinitis, which in turn is associated with nasal polyposis, more frequent respiratory infections, ear infections, hypertrophy of the adenoids: trivializing dust allergy is therefore wrong, because it can significantly compromise the quality of life.
Treatment
Treat yourself more effectively than using only symptomatic drugs today, but it is also important to follow some rules to clean up the house as much as possible: for example it is advisable to eliminate woolen blankets and everything that can accumulate dust such as curtains, carpets and cushions, ventilate the rooms, clean with dust-catching cloths, that do not raise particles, and with vacuum cleaners equipped with Hepa filters that retain a good percentage of allergens. The bed can be a real receptacle for mites and so the mattress should be changed every 8-10 years, the pillows every 6-12 months; the bed linen should be washed at 60C once or twice a week, possibly drying it outdoors.
Desensitizing therapy
The fear of those who do not tolerate dust mites that the annoyances result in a serious asthma crisis: in fact, about half of people with mite rhinitis sooner or later develop allergic asthma of varying degrees of severity. Take care of yourself
important for these patients e allergy therapy involves the use of symptomatic medications, for example antihistamines and steroids by inhalation; for about two and a half years, specific allergen immunotherapy for dust mites, also called vaccine, has been available. These are pills to be dissolved under the tongue, to be taken for at least three years, with which an allergen extract is administered in increasing doses: cWith this therapy, also called desensitizing, the patient’s immune system is taught not to react violently when it encounters the mite, therefore, to tolerate it, acting on the causes and not only on the symptoms of the allergy. Allergen-specific immunotherapy complements the basic anti-inflammatory therapy of asthma, with a mechanism of action based on the extinguishing inflammation that is generated in the airways of allergy sufferers when they breathe the allergen, explains Samuele Burastero, allergist at the San Raffaele Hospital in Milan. The therapy improves patients’ quality of life by progressively reducing symptoms and the need for cortisone-based drugs to control discomfort. If you continue it long enough, the natural history of the allergy changes and you heal: even if you meet the mite, you no longer sneeze.
