The dust mite allergy is the immune system’s response in the human body for a particular protein in the insect. This response stimulates inflammation of the inner wall of the nasal passages, causing sneezing, runny and other signs and symptoms related to hay fever.

 

in some of the people, dust mite allergy is the main reason behind the inflammation and constriction of the lung air passages and that means asthma that result in wheezing in the chest and shortness of breath and other breathing difficulties.

 

Dust mites are like a small spider in size as difficult to see only through a microscope. The dust mite feeds on skin cells, it is also live in a warm humid environment. In most houses, the types of bedding, upholstered furniture, and carpets represent an ideal environment for dust mites.

 

Reducing the number of dust mites in the home reduces exposing to allergy, also there are some medicines prescribed to alleviate the symptoms and help to control the allergy bouts.

 

Dust mite allergy symptoms.

 

Dust mite allergy that causes inflammation of the sinuses passages, the symptoms include the following:

  • Sneezing.
  • A runny nose.

  • In children, waking up from sleeping and itching nose.

 

If the dust mite allergy leads to asthma, the following symptoms appear:

  • breathing difficulties.
  • Chest tightness and pain.
  • Audible whistling or wheezing sound when you exhale.
  • Sleeping difficulty because of shortness of breath, coughing and wheezing while breathing.
  • Bouts of coughing or sizzling become worse with respiratory viral infections such as common colds and flu.

 

The dust mite allergy symptoms range from simple to severe. The simple cases are a runny nose, tears in eyes and sneezing. The severe cases, especially the chronic ones characterized by sneezing, coughing and constant congestion or about of an acute asthma attack.

 

The dust mite allergy causes.

 

Dust mites feed on skin cells in addition to the water absorbing the moisture present in the air around us. Dust mites live at a temperature of 21 degrees Celsius and humidity by 70%. The dust that found at the house contains all the accurate particles, but the greater part of it is composed of human skin cells, and we find that the moth is present in the tissues of the bedding, furniture, cushions and rugs .. Fabrics and upholstered furniture are as a home for moisture, so we find that the bedroom is the first resort to dust mites.

In addition, the dust contains feces and rotting bodies of moths insect, and the protein found in the dust mite is the basis for allergies of these insects.

 

What causes the allergic reaction?

The reason behind the human infection of any type of allergies is the imbalance in the function of the immune system, where the immune system identifying specific proteins as harmful and thus stimulate the body to produce antibodies (IgE) to offset the protein that causes allergic reactions.

The next time the body is exposed to these proteins the antibodies recognize it and send a signal to the immune system to produce anti-histamines and other chemicals that protect the body from bacteria, viruses, and toxic substances. The histamine and these chemicals cause a series of symptoms and signs, but histamine partially responsible for all the body’s responses to the allergy, including inflammation of the nasal passages or the lung.

Dust mite protein causes two types of immune response in the  lung air passages, when the allergens emergence an inflammation happen in the air passages, and with the length and frequency of exposure to this exciting, it result in a chronic inflammation “asthma attack”, or causes sudden constrictions in the air passages which called “bronchial spasms”.

 

Risk factors:

The following factors increase the possibility of injury of dust mite allergy:

  • The family history of allergies when exposed to dust particles.
  • Exposure to high levels of dust mite, especially in the early stages of age increases the risk of injury of dust mite allergy.
  • Age, the most exposed age to the infection of dust mite allergy are the childhood or the early adulthood.

 

Complications :

Chronic persistent inflammation that infects the tissues of the nasal passages due to dust mite allergy can lead to blockage of the sinus cavity, which is a cavity connected to the nasal passages, and this increases the possibility of infection there. People that suffer from dust mite allergy and asthma have difficulty in controlling the symptoms of the crisis, and the increased possibility of repeating the crisis bouts, which requires immediate emergency care.

 

Seeing the Doctor.

  • Write down a list of medicines, vitamins, and supplements that the child or a person uses.
  • Asking about the need to stop certain medications, such as antihistamines because they affect the results of allergy tests.
  • Writing the important questions that the patient is willing to ask it to the doctor.

  • Do the symptoms that have emerged are the symptoms of dust mite allergy?
  • Are there other possible causes for these symptoms?
  • How will the diagnosis be?
  • How will be deal with dust mite allergy?
  • What are the required tests to do?
  • What are the preventive measures to avoid the incidence of this type of allergy?
  • How to deal with asthma besides the dust mite allergy?

 

What does the patient expect from the doctor?

The doctor will ask you some questions, for that the patient should be ready to answer for diagnosis:

  • What are the symptoms that appeared?
  • When did these symptoms begin to emerge?
  • Do the symptoms appear at certain times throughout the day?

Skin test ( SPT ).

In this test is about pricking and exposing the skin of small amounts of the protein of dust mites which leaves for 15 minutes. If a person has a sensitivity of this protein the symptoms will develop to the appearance of a rash at the site of the skin test.

The side effects of this test are itching, redness and usually, disappear after only half an hour.

 

Blood test.

The blood test measures the immune system response to the protein of dust mites, by measuring how much antibodies in the bloodstream which is known as (IgE), where a blood sample is sent to a medical lab for testing for the presence of allergies or not. Resorting to the blood test just in the case of a skin disorder precludes of skin test or in the case of a conflict of drugs interact with each other.

 

Treatments & Drugs:

The best ways of treatment and prevention are to avoid exposure to dust mites or dust as much as possible and work to get rid of them by keeping the places where humanly resides in clean .. but it is difficult to get rid of them completely.

  • Corticosteroid drugs: it reduces inflammation and reduces the cold, and there are drugs takes the form of spray for nose given as a simple dose and it is not linked to the risk of long-term use, such as corticosteroid tablets.
  • Decongestants: it helps to reduce the bloated tissues in the corridors of the sinuses, and facilitates breathing process. It also sometimes the treatment is a combination of antihistamine tablets that available in pharmacies and decongestants. Decongestants working to raise blood pressure, so patients that suffer from high blood pressure or cardiovascular diseases, they should not resort to such medicines.

 

Men who suffer from Benign prostatic hyperplasia this drug makes your situation worse. The solution is to consult your doctor before resorting to decongestants.

 

Decongestants are used as a spray for a short period of time to alleviate symptoms .. and using it for more than three days respectively gives adverse consequences and cause more congestion.

 

  • Immunotherapy: It is a series of doses of allergen proteins, where the immune system is trained to do not make an allergic response when it exposes to the allergens, and the person is given a small dose or two of the allergens throughout the week. The dose is increased gradually and continue for 3-6 months, and the situation stability doses are taken every four weeks over 3-5 years. The immune therapy is resorted to if the other types of treatments were not effective.
  • Nose lotion: using brine or saline as a solution in order to ease congestion and sneezing, you can make this brine in the house by adding a ¼ spoon of salt to two cups of warm water. And other types of treatment.

 

Home Treatments.

It is hard to eliminate dust completely at home or the workplace, but the best way to avoid dust mite allergy is to avoid exposure to dust as much as possible and reduce the number of mites in the home in the following ways:

  • use of the anti-allergy bed linen: These covers are made of vinyl or special fabric so as not to allow to the moth to live in the pillow or mattress.
  • Change the sheets and washing them every week: Including blankets with hot water at a temperature of 55 ° C sufficient to kill the moth. If sheets and furnishings have not washed in high temperature, it is placed in the dryer for at least 20 minutes at a temperature of over 55 degrees Celsius. Washing and drying to kill insects and to get rid of allergens, and freezing unwashed furnishings for 24 hours helps to kill insects but it does not help to get rid of allergens.
  • Keep on lower rates of moisture: The reasonable moisture is between 30-50%, and air conditioners help to keep moisture levels in the lower rates and there is a tool to measure moisture levels in the air can be purchased.
  • Choose furnishings wisely: Choose textiles that do not attract the dust such as wool or those textiles that are hard to launder frequently.
  • Buy toys that can be washed easily: Especially those are easy to wash with hot water and keep them far away from the bed.
