Seasonal Allergies

 

    Seasonal allergy or it is known as hay fever also, it considers to be an allergic reaction to pollen and other small particles in certain times of the year, also people can be infected of allergic rhinitis at any time of the year. In spring, the trees that carry pollen causes seasonal allergic rhinitis and in summer weeds and grasses produce pollen but in autumn the main reason is weeds.

     Annual allergy ( that continue the whole year ) caused by factors that present throughout the year like dust mites, fungi and animal fur, and feathers. These allergens can be found in clothes, pillows, fabrics, upholstery fabrics, thick carpets, and playmate, and it is in common for people to be allergic of more than on type of allergens.

 

The symptoms of seasonal allergic rhinitis.

     The immune system identifies the allergens ( pollen, fungi, and animal fur … ) as substances attack or invades the body, and the body reaction to the launch of the chemical substance which is Histamine. The Histamine causes inflammation ( swelling and redness ) of the sinuses, nose, mucous membrane of the eye and stimulates sneezing also, the swelling happen to resist the allergens to enter the body, in addition, that sneezing is a way to flash the allergens out of the body. The Histamine allowed fluids to enter to the nose tissues causing congestion, itching, and runny nose.

     People that infected of allergic rhinitis suffer from sneezing dramatically, runny nose, swelling of the eyes and fatigue, these symptoms may happen in all life stages but most of the people infected of allergic rhinitis before thirtieth.

 

How can you recognize the allergens?

     The season that you infected with allergic rhinitis in will determine a list of factors that causes allergy for you, to determine why a doctor may examine the skin to identify the substances that cause allergy for you.

     Skin examination includes put an extract of the substance ( which is suspected into because of the allergic reaction of the patient ) in the network and placed on the arm or back, the doctor then prick the skin until the suspected substance entering to the outer layer of the skin ( Epidermis ) , the areas become red and itchy indicate to the substances that stimulate the immune system reaction that resist the substances    ( allergens ).

     The doctor may also perform a blood test to check levels of antibodies produced by the immune system, the high level of certain antibodies could indicate to certain substances causing the allergic reaction.

 

Why do just some people suffer from the seasonal allergy?

     It is not known why some people infect of allergies while some others not. However, there is evidence that the seasonal allergies and some other types of allergies are hereditary ( passed down from parents to children ) the people who suffer asthma or eczema are the most susceptible to infection allergic rhinitis seasonal or annual.

 

Why allergic rhinitis symptoms be worse in some days and others not?

     Despite the pollen season for certain plants limited to a particular geographic area, but that the weather plays a big role in determining the number of these pills ( and other allergens such as fungi ) in the season and in the day. The severity of allergy symptoms usually commensurates with the rise and fall in the number of molecules of the allergen for that person.

 

Allergic Rhinitis Treatment.

     The most effective treatments are simply avoiding exposure to the allergens, some types of air-conditioning filters out %99 of the pollen in the air, and gags reduce ( such as those surgeons worn ) the amount of inhaled allergens when a person is out of the house.

     If you suffer from eye allergies, try wearing sunglasses closed from the aspects ( similar to swimming goggles ) to protect the eyes from pollen. If you exposed to pollen, wash your eyes and your glasses, put cold compresses on the eyes to relieve the symptoms and you can consult your doctor to use the treatment that relieves the symptoms.

     The effective treatments include in the cases of allergic rhinitis: antihistamines that prevent the chemical substance that causes the symptoms, the Cromolyn which prevents mast cells (which is one of the types of red blood cells) secretion of histamine in addition to topical nasal steroids that reduce swelling and inflammation.

 Antihistamine: The antihistamines are usually effective in treating mild cases of allergic rhinitis, antihistamines that do not prevent the secretion of histamine, but it prevents the series reactions that histamine stimulates it, and this, in turn, reduces the symptoms. However, most of the antihistamines may cause drowsiness and therefore should not be taken while driving, drinking alcohol or with other drugs cause drowsiness. But there are some types of antihistamines that do not cause drowsiness, but the impact on each person is different and therefore should be careful when using a new medication.

 Decongestant: the decongestants help ( tablets, drops or sprays ) opening of the nasal passages and improve breathing, but keep in mind that some types of decongestants have an opposite effect after several days the congestion may become worse, also these drugs can cause addiction ( habituation on medication ).

 Cromolyn: This medication to prevent one of the types of cells involved in the allergic interaction, unlike some other medicines, the effect of Cromolyn need about two weeks until the patient feels it, but on the other hand, positive, can be used for long periods without causing side effects.

 Nasal sprays containing steroids: These sprays reduce a lot of the interactions of allergens, these drugs are given by prescription.

 Saline nasal sprays: These sprays help in removing the allergen lingering in the nasal passages and keeps the moisture of these passages.

 Eye drops: used to relieve allergic eye problems.

 

The difference between seasonal allergy symptoms and cold symptoms.

     It is necessary to find out if what you are suffering from allergies symptoms or cold symptoms, with different ways of treating the two cases. When comparing the symptoms of allergies and the common cold of the most important things that must be taken into account is the period during which a person suffers from the symptoms, cold symptoms usually only last for a few days to a week while allergies symptoms you continue for a longer period. If you have symptoms persisted for more than seven days, you should see your doctor.

 

The following table shows the differences between the symptoms of seasonal allergy and cold:

Antihistamine Injection.

     Injection against allergies ( immunotherapy ) it is a treatment that the patient injected with small doses of allergens are taken under the skin, and these allergens include: pollen, pet dander, dust and even poison found in bites Some insects ( such as bees, wasps, and ants). In some cases, the doctor uses injection against allergy to remove allergy from certain medications , and this is used when a drug is very important to the health of the patient and does not have an alternative, but most of the doctors prefer to look for alternatives drugs for the drug that the patient is allergic to.

     The injections against allergies target are to increase the body bearing to the allergens, and in many cases, the level of body bearing increase to these allergens significantly, thereby reducing the symptoms such as a runny nose, itchy eyes, itchy throat dramatically.

 

 This achieves one or more of the following benefits:

  •  Prevent the symptoms.
  • It reduces the recurrence of the interaction of body allergic reactions.
  • It reduces the severity of symptoms when they occur.

     The reports have shown that a high percentage of success in people who are taking these injections, especially in the treatment of allergic rhinitis, according to the annual report of the American College of Allergy, Asthma, and Immunology:

  •  81% of the patients felt that the treatment was successful.
  • Review emergency clinics by 68% the proportion decreased.
  • It decreased the number of days in which the students do not go to schools by 75%.

 

     It is not known how these injections increase the body bearing. In some cases, the researchers found that these injections stimulate the production of antibodies to type G ( immune globulin G ) that are linked to the allergens, and this is an important link because it prevents the immune globulin E of linking with the allergens. The globulin is immune E inducing blood cells, to begin with, an allergic reaction, so it can reduce these injections from the body’s production of immune globulin E.

     Before injection therapy against allergies ( immunotherapy ), patients subjected to intense sensitivity tests (skin tests, blood tests and clinical examination) in order to determine the allergens to them.

     The first syringe containing a brine and small dose of the allergens , then the patient must be under observe for 30 minutes to make sure that the injection did not induce him allergic reactions such as shortness of breath, runny nose or a narrowing in the throat, also the patient must be observed for any symptoms of hypersensitivity, a rare case of a severe allergic interaction which is life-threatening and requires immediate medical care.

     Patients who do not happen an allergic reaction to them of small doses of substances that cause allergy can leave the clinic until the next session. If an allergic reaction happened after leaving the clinic, the patients must immediately return to the clinic or emergency section.

     After the first syringe, the patient will return for follow-up the treatment on periods. Usually, they are given these injections once or twice a week over several years, and in each session, the amount of the allergens that are injected under the skin is increased.

     when the immune treatment is effective, significantly it will reduce the sensitivity of the patient to this substance and shows the benefits of the treatment after six months only. At the end of the first phase of treatment, the syringes are given less frequently, and usually on a monthly base for a period of three to seven years. At a certain stage, the patient’s bearing degree may increase to the stage that he does not need more syringes. Usually advised stopping the treatment after the appearing of the minimal symptoms over two consecutive sessions of the treatment. People who feel symptoms later may be subject to another round of immunotherapy ( injection against allergy ).

 

The cases that are treated by injection against allergies.

     Not recommended giving injections against allergies for all patients who suffer from allergies or asthma, the process is time-consuming and not effective at all. The doctors usually try to use other methods of treatment ( such as taking medications or change the pattern of a person’s life to reduce exposure to allergens ) before they advise of injection against allergies treatment.

 

The doctor’s advice the patients with injection against allergies if they were:

  •  Treated by other methods ( such as lifestyle changes or other allergy drugs ) and no avail.
  • Not able to afford the side effects of medication allergies.
  • Suffering from allergy symptoms most or all days of the year.
  • Not able to avoid exposure to allergens in their daily lives.
  • Has an allergic reaction to allergens present in the air such as pollen, dust, fungi and animal dander.
  • Suffering from multiple complications because of the sensitivity of such as headaches, asthma, conjunctivitis, sinusitis and ear infections.
  • Suffering from an allergy to insect bites, where the allergic reaction can be very serious and life-threatening, and this supports the need for the use of immunotherapy ( injections against allergies ).

 

    Injection against allergies can be used also for the treatment of allergic asthma in children, and this leads to reducing symptoms and reduce the need to use allergy treatments in children who have allergies induce asthma symptoms.
