ALLERGIES




PART 2.


STIFFLING THE SNIFFLE

In the previous article dated December 20, 2012, we dove deep into understanding a common problem faced by children with runny noses - Allergic Rhinitis. After the surge of information on common triggers, tips on avoiding and how Allergic Rhinitis can affect your child, you are now probably wondering what can be done to actually treat this syndrome. The following suggestions in this TWO-PART series of frequently asked questions may come in handy to you especially if your child suffers from the constant sniffle.

IS AN ALLERGY TEST REALLY NECESSARY FOR MY CHILD?

The common allergy test include blood test to look at levels of lgE antibodies to specific allergens and skin prick testing. (If you have already read the previous article dated 20/12/2011, you would have learnt that when in contact with an allergen, your child's immune system cells would release antibodies, specifically Immunoglobulin E (lgE).

Basically for the blood test, the higher the lgE levels, the more severe the allergy. Skin prick testing is tricky to do, as this involves actually breaking the skin with a sharp needle to allow solutions of allergens to seep into the skin, resulting in red swellings (like mosquitoe bites). The bigger the swelling, the more severe the allergy. Children may not take to kindly to a needle prick.

Whatever the outcome of the allergy testing, the treatment is the same across the board. In other words, if a patient is allergic to dust mites, the same antihistamines and steroid sprays apply as for dog hair or for fungus. All roads lead to Rome, one may say. therefore, are allergy test really necessary in allergic rhinitis?

The short answer is no, but bear in mind that allergy testing may have other applications and purposes in the treatment of asthma and eczema.

HOW IS ALLERGIC RHINITS TREATED?

Firstly, just do nothing and wait-and-see. If symptoms of allergic rhinitis are mild and tolerable, very little may be achieved by giving medications. Therefor, blowing your nose, slapping on a grin and getting on with it is all that is really required.

The second option is to medicate. There is vast array of medications. The commonest include antihistamines and steroid sprays. Each may come with pseudoephedrine* making the drug more efficient in decongesting the nose. The most powerful drug class are nasal corticosteroid sprays. It could be said that steroid sprays are my favourite medication to alleviate the symptoms of allergic rhinitis. Steroid sprays work to reduce all symptoms of allergic rhinitis and have been so good that nothing else really comes close to its efficacy. There are other than the two above.

The third method is surgery (for severe cases). Surgery is really only needed when medications have either failed to achieve its aim, or when the patients feels the change in symptoms is unsatisfactory. Surgery to reduce the size of the nasal turbinates or making the septum straighter (septoplasty). Endoscopic sinus surgery makes the channels leading into the sinuses, which may help to reduce headaches and reduce the chances of infection of the sinuses.

Please note that surgery will not eliminate allergic rhinitis. Keep in mind that an allergy-reaction will always be determined by the over-reactive immune system and environmental factors. No amount of surgery will do this, but surgery does help to lighten the burden of a particular symptom. Antihistamines and steroid sprays may still be needed after surgery.

HOW SAFE ARE STEROID SPRAYS REALLY?

Very safe, is the succinct answer. Much is written in the internet about the side effects of steroid sprays. Examples of these include thinning of mucosa, bleeding and growth retardation. I do not subscribe strongly these fears, as in the clinical practice they have yet to actually come across such cases. The real side effects of steroids occur with orally ingested or injected, high dose steroids taken for an a continual basis from months on end. Steroid sprays on the other hand are topical, meaning that the drug stays above the skin surface with negligible absorption into the body.

However, the doctor respect the fears of parents. The doctor compromise by allowing parents to stop the steroid spray once symptoms are better after two or three months. But, inevitably, symptoms will return about two weeks or more after cessation of the spray. If symptom recurrence is bad enough, you can start again!

WHAT ELSE CAN I DO IF I DON'T LIKE MY CHILD TO BE ON A TON OF MEDICATIONS? WILL TAKING VITAMIN C HELP?

Naturally there are alternatives to antihistamines and steroid sprays. Since dust mist is still the commonest cause of allergic rhinitis, strategies against dust mite are widely used. Examples include cleaning and changing mattress sheets every week and washing them in hot water, dust mite covers for pillows and mattresses, powerful vacuum cleaners, chemicals to kill dust mite, air-filters, air ionisers etc. My personal opinion is that these are either too expensive or take too much effort. From a purely pragmatic viewpoint, tolerating symptoms or taking medications are still the most cost-effective.

Physical exercise has been said to "cure" symptoms of allergic rhinitis. Any strenuous physical activity will result in the nose's mucosa shrinking, which allows more air to be inhaled. This normal physiological response is temporary and in noway result in permanent nasal block resolution of allergic rhinitis.

Parents often vouch for Vitamin C as the cure-all for many ailments. Claims that Vitamin C wards off viral infections have come under scrutiny recently and they are starting to look dubious. I have not seen anything to support the use of Vitamin C for allergic rhinitis. I cannot make any logical connection between Vitamin C and allergic rhinitis.

ALLERGIES




PART 1. 
UNDERSTANDING ALLERGIC RHINITIS IN CHILDREN

Runny noses and constant sniffles are a common recurrence among adults and children alike. This phenomenon is inevitably labeled as a 'sinus problem' and often this guess is confirmed after checking with their respective doctors. However, it is really easy for many of my patients to confuse infections; both viral and bacterial, with actual allergies, subsequently leading to a less effective treatment option. For your reading pleasure, I will now explain the truth on alergies in this TWO-PART series of commonly asked questions.

WHAT IS AN ALLERGY?

An allergy occurs when the body's immune system, or the intrinsic defence system, reacts against substances or antigens to many people. These can be separated into two categories: harmful antigens and harmless antigens (allergen).

Viruses and bacteria fall under the HARMFUL category while although dust-mites, cat and dog fur and plant pollens may seem like the enemy, they are indeed harmless.

In simplified medical terms, when in contact with an allergen, your child's immune system celss would release antibodies, specifically immunoglobulin E (lgE). These antibodies bind to the allergen molecules, which eventually leads to the release of the chemical histamine. This chemical is known to cause the symptoms associated with allergy such as the common sneeze and sniffle.

Allergies are commonly suffered through the generations, as there is a genetic or hereditary basis that governs why the immune system reacts against allergens.

WHAT, THEN, IS ALLERGIC RHINITIS?

It is the condition where an irritation or allergy happens in the 'carpet lining' or mucosa, of the nasal cavity and paranasal sinuses. The sinuses are eight hollow cavities within the facial bones and each has a connecting doorway into the nasal cavity.

Allergies may also occurs in the lungs, skin and eyes, known respectively as asthma, eczema and allergic conjunctivitis. A child may be susceptible to one or more of the above types of allergies.

When a particular allergen is inhaled into the nose, it comes into contact with lgE that is specific for it. Histamine release leads to swelling of the mucosa and copious mucus production, causing typical sysmptoms of nose block, sneezing, itch and runny nose.

Naturally, there is avariation in severity and frequency amongs a range of patients. Some may only have blocked noses, some only sneezing and itching, but others may be faced with the full hand of symptoms.

AT WHAT AGE DOES ALLERGIC RHINITIS START?

It is believed that allergic rhinitis starts at the tender age of four, in contrast to the other allergic problems of asthma and eczema that tend to begin in infancy. However, runny and blocked noses are very common in children below four years of age. making it hard not to believe that in fact allergic rhinitis starts earlier than this in some children.

WHAT ARE THE COMMON FACTORS CONTRIBUTING TO ALLERGIC RHINITIS?

The fundamental causes vary from country to country, depending on climate and degree of urbanisation, but only inhaled allergens directly cause allergy in the nose.

Examples of allergens for tropical climates like Malaysia include dust-mite excretions, fungal material and dog or cat dander. Even cockroaches can be a threat to your child's environment. In temperate climates with the four seasons, there are also plant pollens of tree, flower and grass varieties that contribute to this.

DOES WEATHER AND AIR-CONDITIONING MAKE ALLERGIC RHINITIS WORSE?

Parents commonly report that their child's sneezing and runny-nose worsens when spending a day out under the sun or when cooped within an air-conditioned room. They are half right.

Changes in humidity, temperature and certain air pollutants have an independent irritant effect on the nasal mucosa. This irritation makes the mucosa swell up, making the symptoms of allergic rhinitis appear to be worse. This is in fact a separate reaction not to be confused with allergic rhinitis.

Air pollutants may be divided into indoor and outdoor categories. An example of an outdoor air pollutant is diesel fumes while indoor pollutants include household products, pesticide and even tobacco smoke.

WHAT ABOUT FOODS THAT WE TAKE?

Food subtances may cause oral and systemic (asthma and eczema) allergic symptoms. It is said that food substances only rarely directly make allergic rhinitis worse.

Once again, it is inhaled substances that serve as allergens for allergic rhinitis. However, certain foods may modify the immune system, so that it becomes more reactive, thereby also making allergic responses more intense. This is an indirect way, in contrast to the direct allergen way.

HOW ABOUT SWIMMING?

Most swimming pools are chlorinated and it is only this chemical that would contribute to an allergic while swimming, if at all. Chlorine-related gas sits just above the surface of the water. This gas serves as an irritant, just as the weather and air-conditioning would. I truly hope you would understand that your child's allergic rhinitis is actually not make worse. What he/she might experience is a temporary irritation due to the chlorine.

Swimming is an excellent form of sport and excercise. I think a child should not be deprived of the opportunity to do so.

ALLERGY

 Believe it or not, most people have allergies
Allergies usually cause symptoms of sneezing, watery eyes, red eyes, itchy eyes, itchy nose and itchy throat. Discover how a runny or stuffed nose can be a sign of allergies with help from a nurse and respiratory care practitioner in this free video on allergy symptoms.


Symptoms of allergies. Sneezing normally will be presented with dark circles under their eyes. Watery eyes, red eyes, itching eyes, nose and throat. You'll have a runny or a stuffed nose. Now these are caused by pollens and molds and dust mites and chemicals and animal dander. The one thing you want to make sure of is that you guard against the anything that would cause you to have an allergy. So when you have these symptoms, I would make note of it so that you can stay away from all the pollens that come out in springtime and try to if you have to wear a mask and wear a loose fitting mask, not too loose where the pollens can get in, but you have to be careful of that too because with chronic lung disease, have a difficult time being able to breathe without putting a mask over your face. But just knowing that there are things that can help you with allergies but knowing what the symptoms are very important to you. So be aware that allergies can cause some difficulty and make your life very uncomfortable.
