6 : cures of allergic diseases

This time, I’m going to write about cures of allergic diseases.

First, allergic diseases are cased not only by allergic reactions but many other factors. For example, autonomic dysfunctions, psychological factors, the pollution of the environment, weather conditions, viral infections and bacterial infections and so on. If these factors went the limit, allergic diseases comes out. Clearing antigens are the basis of curing allergic diseases, but trying to not to cause the allergic disease is important to curing. In order to do that, these are necessary for curing to reduce the factors, skin care, environment arrangement, eat balanced diet, taking exercise to smith one’s autonomic nerve. And antiallergic agents has effects to only typeⅠ allergies.

Next, I will write about cures by diseases.

As to the cure of pollen allergies, there are five points.

1 cleaning of antigens

 That is to say try to not to breathe in pollens. For example, wearing a mask, dusting off from futon hung out.

2 antihistamines

 By hold down operation of histamine, it can reduce of the allergic disease. It takes effect at once. These are used as medicine mainly, and as injections, and applications.

3 antiallergic agents

 These works reduce symptoms of allergic diseases by holding a operation of except histamine. There are much kind of antiallergic agents, and each of these may effects different matters. I recommend taking these before two weeks pollens begin scattering because these don’t take effect at once.

4 adrenocortical steroids

 These works to reduce operations of T cells and so on. These may causes secondary effects so these are said the last resort.

5 desensitization therapy

 This is a way of trying to adjust to antigens.

As to food allergies, it is essential to cures by drugs as pollen allergies when emerged, and food allergies are more essential to not to eat the antigens. First, let’s be examined what foods are antigen at hospital. If the antigens are proved, you should try to remove these. If you are a child, it is essential to think about meals to not check the growth or development of you. If you has families or friends who is allergic to any foods, you should cooperate with these.

As to atopic dermatitis, there are five points.

1 topical treatment of skin and skin cares

 One of the causes are decline of faculties of skin. If skin is sensitive, it is liable to cause irritations.

2 antiallergic agents

 There are medicines of atopic dermatitis, and applications are used mainly. It may reduce symptoms to use moisturizing agents.

3 immunosuppressive agents

 These are new type drugs so these secondary effects are unknown yet. So these are used to only atopic dermatics.

4 environmental maintenance

 The most important is clearing the antigens. For example, scurf, body hairs, feather, saliva, urine of pets, and tics may be causative agents. So the first step is cleaning.

5 adjunct therapies

 These are some ways to reduce symptoms. For example, disinfecting staphylococci, ultraviolet treatment, therapy by Environmental Protection Agency and so on.

5 : complications

This time, I am going to write about complications of allergic diseases.

First, I will explain about allergic diseases simply. It is said that allergic diseases are well known for accompanying these complications such as bronchial asthma and sinusitis and so on. Especially, there is a very high chance of accompany complications of allergic diseases of respiratory system so it is advocated the view of “one airway one disease”. It is said that curing for asthma and sinusitis at the same time is so effective.

Main complications of these are nasal polyp and sinusitis, asthma, bronchitis, eczema, and hypertrophy of tonsil and infectious diseases of ear and the like. These may cause allergic asthma and tachycardia, loss of consciousness, decrease of blood pressure, a feeling of listlessness and shock right now if these were serious illness. Children’s allergic rhinitis are accompanies bronchial asthmas with probability of about 30%, and atopic dermatitis probability of about 20%, and vice versa, the probability of that allergic rhinitis accompany bronchial asthmas are about 70~80%, and it’s very high probability as expected.

For example, allergic rhinitis (pollen allergies) may complicate allergic asthmas and it makes it easy to catch cold. Because, noses connect with tracheas. Noses works to clean air as a filter when breathe in, and send moist air to tracheas as a humidifier. But if my nose is stuffed up by an allergic rhinitis, I can’t breath but mouth breathing. In mouth breathing, it has been arranged that I breathe in dirty and cold and dry air directly, so it complicates bronchial asthma and the like, as well as it makes have a weak chest. So it’s important that cure to be able to breathe nasal respiration from childhood.

About food allergies and hypersensitivity to drug and the like may accompanies nettle rash all over, having difficulty in breathing and disturbance of consciousness, and the worst, these may bring to death.

Next, I am going to explain about “allergy march”. Do you know it? It is said that emerging allergic diseases are the lowering of the age in recent years, then, allergy march is a burdensome phenomenon that various allergic diseases go in different time one after the other as if allergies are marching in brief. For example, a child develops an asthma in babyhood stage and be cured, but in early childhood and be cured, and develops a pollen allergy insecurity. Generally, “allergy march” is developed who has atopic background and be sensitized while whose mother is pregnant so it handed down. After one’s birth, not one but various allergic diseases come out by touching each antigen. For example, atopic dermatitis, asthmas, dyspepsia, allergic coryza, pollen allergies and so on, and in due course, these switch atopic disease adult type. It is thought that the cause of changing allergies is by shift the environment for one's age. But all of who has atopic background are not necessarily came out allergy march. And part of the patients may be cured as a child.

I referred to Wikipedia and these websites to write this.

4 : Pollen allergies

This time, I am going to write about pollen allergies.

First, pollen allergies are one of type Ⅰ allergies. These are caused by pollens touch to mucous membrane of eyes or noses and the like, and causes sneeze paroxysmal and repeatability and so on. In japan, pollen allergies of Japanese cedars are the most part of these. Of course, it may cure spontaneously like other type Ⅰ allergies. It is said about 10~20 percent of the patients who is allergic to pollens about that.

It is said that the number of patients who are allergic to pollens are about 30 percent of people in japan now, and about 5~10 percent in America, and more than 15~20 percent in UK, and about 10~40 percent in Australia or Turkey, and about one person per 6 in Canada and about 10~20 percent of people all over the world. And it is also thought that about 30 percent of children under 16 years of age are allergic to pollens. Besides, it is thought that patient of these have increased around 3~4 times in 1970 and doubled in recent decade years.

Next, I will write about symptoms of pollen allergies.

As general symptoms, main symptoms are sneeze and snivel and a stuffy nose and an itch on eyes. As secondary symptoms, because of a stuffy nose, it makes one’s cold and the like by mouth breathing. And, foreign body sensation in eyes, eye mucus, itch in ears, headaches, slight fevers, languors may appear. And it causes digestive symptoms (diarrheas, nauseas, stomachaches and so on) by swallow pollens in mouth or snivels include pollens. And lack of sleep and short attention span, upset and anorexia, low spirits may arise. Depends on quantity and kinds of these, it may causes anaphylactic shocks. However, these symptoms depend on the individual.

Then, it is said that airborne pollen levels are not correlative with symptoms.

Next, I am going to write about botanical causes of pollen allergies.

These are reported to exist more than 60 varieties. Most of these are japanese cedars, and there are many people who have allergies by Japanese cypress and ambrosia artemisiifolias, pine trees, family comprising the true grasses, artemisia vulgaris indicas and other plants. Especially, most of patients who have pollen allergies by japanese cedars are also have Japanese cypress allergies.

Then there are regional differences. In Hokkaido, there are few japanese cedars so pollen allergies of family comprising the true grasses and white birchs are the most. There is a social problem because of alnus firma oillens. And ambrosia artemisiifolia pollen allergies are the most in America, and white birchs are in Northern Europe, and family comprising the true grasses allergies are the most in Europe. Because of go on snuffing particular pollens, it is said that whatever pollens of plants may cause allergies. But is little case that Japanese became rice plant pollen allergies.

In recent years, it is problem that pets have pollen allergies or other any allergies.

I referred to Wikipedia to write this. 

3 : food allergies

This time, I’m going to write about food allergies.

First, I am going to explain about food allergies simply.

I explained the process of allergies last time.

Food allergies are classified type1 allergies.

Everybody who has atopic diathesis has a possibility of cause symptom of food allergies suddenly.

A food allergy may causes anaphylactic shock and it is a matter of life and death even if the allergen was ate very small amount. Buckwheat and peanut, fish and shellfish, are particularly well known about that.

From infants through childhood, as main allergens, milk and egg accounted for more than half. Become more adolescence, shellfish, wheat, fruits, seafood are the main allergens and milk allergies reduce. In this way, if someone who has an allergy becomes an adult, whose allergies may to get better by some chance.

Next, I’m going to explain about foods that may be allergens.

These are foods the most well known as an allergen.

 Egg (yolk or albumen or both)

 Wheat

 Milk from cows goats or sheep

 Peanut

 Buckwheat

 Shrimp

 Crab

These 7 items are called “specific raw materials” and be bind to inform whether contain these or not in a merchandises and foods and so on in japan.

Depending on the circumstances, shrimp or crab allergies are said “shellfish allergy” all together. These are added specific raw materials for the last several years.

These are second famous foods as allergens.

 Ear shell

 Cuttlefish

 Salmon roe

 Orange

 Kiwi fruit

 Beef

 Walnut

 Salmon

 Mackerel

 Soybean

 Chicken

 Banana

 Matsutake (mushroom)

 Pork

 Peach

 Yam

 Apple

 Gelatin

These 18 items are called “equivalent specific raw materials” and encouraged to inform whether contain these or not in a merchandises and foods and so on in japan.

These are a part of little known foods as allergens.

 Rise

 Barley

 Millet (barnyard grass)

 Corn

 Kidney beans

 Pea

 Almond

 Cashew nut

 Coconut

 Chestnut

 Strawberry

 Melon

 Mango

 Avocado

 Western pear

 Tomato

 Celery

 Parsley

 Onion

 Watermelon

 Carrot

 Potato

 Sweet potato

 Pumpkin

 Spinach

 Bamboo shoot

 Garlic

 Sesame

 Mustard

 Japanese horseradish

 Cacao (including chocolate and cocoa)

 Short-neck clam

 Oyster

 Scallop

 Octopus

 Horse mackerel

 Sardine

 Cod

 Tuna

 Cod roe

In these, it is especially well known that chocolate allergies are.

Foods such as cocoa and chocolate include angioedema substance called tyramine, and due to this. In addition, people be allergic to it may appears symptom because the cocoa also contains nickel (metal). Symptoms of these are varied diarrhea, vomiting, nosebleeds, abdominal pain and cramps and so on. And a nickel allergy may also cause anaphylactic shock. Deaths of it have been reported in Japan. Allergy symptoms may appear suddenly even those who had not come out any symptoms until now to eat chocolates. It is called "Valentine's Day syndrome" that the people who come to see a doctor with a chocolate allergy symptoms immediately after the day of Valentine's Day on February 14.

In this way, the foods that may be objects of indication in jure are determined by taking into consideration by the number of onset and severity in general.

I referred to Wikipedia to write this article.

2 : cause

This time, I’m going to write about process and cause of allergies.

Allergies are not congenital diseases. From arrived, touching various substance, It became sensitive to one’s particular substance and it causes allergic reaction.

Allergies are not congenital diseases but there is descent of predisposition. But it does not always come out. It is possible that you have the basic cause if you have relatives who has allergy if your parents doesn’t have allergies. This hereditary cause is said “atopic diathesis”. In certain circumstances, genealogy that has atopic diathesis, the baby may be caused allergy symptom by food the mother ate in mother’s milk.

Soybeans, milk, eggs and so on… foods what may be allergens are contain a lot of protein. It said that it is cause of food allergies.

Protein are decomposed into amino acids, it said polypeptide that amino acids are not fully decomposed. It is also said cause of food allergies.

Said simply, for living thing, allergies are prejudicial immune reaction.

First, I’m going to explain about it simply.

Essentially, immune reaction is helpful and indispensable operation for living thing. For example, it works to meet and neutralize and take out the foreign object (=antigen), and exclude it from internal for keep one’s body in tone and protect from harmful thing.

Immune reaction can be divided “humoral immunity” and “cellular immunity”. It is humoral immunity that immune reaction is by the substances called “antibody”.

I will explain with some illustrations that I drew very simply.

Humoral immunity works by some specific cells like these.

If any antigens invade in the body, macrophages will take in these and take these to bits. Next, macrophages inform helper T cell and B cell of information about these.

B cells unite with antigens.

Helper T cells propagate and secrete protein called interleukin, and be operated by interleukin, B cells differentiate into antibody producing cell and　turn out antibodies against the antigens. 

The antibodies unite with the antigens, and these are eaten by macrophages.

Some of B cells are turn into memory T cell and hold information about antigens a certain period.

This is normal process of humoral immunity.

Main human antibodies are divided five types (IgG, IgA, IgM, IgD, IgE) and each of these unites with particular antigens. Antibodies called “IgG antibody” are main of humoral immunity, and called “IgE antibody” causes allergies. Who has atopic diathesis is liable to makes it a lot.

Next, I’m going to explain about allergic reaction.

In allergic reaction, macrophages take specific thing (allergen) for harmful antigen. Allergens itself are not harmful thing.

If particular allergens invade in the body, macrophages take in these and take these to bits and inform helper T cell and B cell of information about antigens just as normal humoral immunity.

Helper T cells secrete interleukin and operate B cells, but B cells turn out IgE antibodies. These unite with mast cells and activate. If allergens invade in the body again, the antibodies on mast cells unite with these allergens. Then mast cell break and give off chemical substances called “histamine”. These work to cause inflammation.
