What is cat pelt allergy
What is asthma?
Asthma is a condition that causes swelling and inflammation inside the airways of the lungs. This inflammation and swelling is there to a greater or lesser degree every the time in people with more inflammation there is the harder it becomes to breathe. People with asthma also own over-sensitive airways, so their airways react to triggers that do not affect other people. When sufferers come into contact with something that irritates their airways (a trigger), it can cause their airways to narrow.
Allergy testing is the best diagnostic tool and the best road to treatment for dogs that are suffering from moderate and severe allergies. There are several diverse testing methods available. The most common is a blood test that checks for antigen induced antibodies in the dog’s blood. Intradermal skin testing may also be performed.
In this method of testing, a little quantity of antigen is injected into a shaved portion of the dog’s skin. This is done in a specific pattern and order so that if the dog shows a little raised reaction, the offending antigen can be identified. After a period of time (hours), the shaved area is examined to detect which antigens, if any, created a reaction. Allergy testing is performed to develop a specific therapy for the allergic animal.
Allergy in Children
The bulk of allergic disease occurs in childhood, with asthma, allergic rhinitis, and eczema and food allergy comprising a significant percentage of the workload of doctors dealing with children in primary care and hospital paediatric departments.
In a recent large UK survey, 20% of children were reported to own had asthma in the previous year, 18% had allergic rhino conjunctivitis (hay fever) and 16% had eczema. This represents a massive increase in prevalence compared with similar studies in the s where prevalence rates were 3 fold lower. Of these children 47% had at least two co-existing conditions e.g. asthma and eczema. Read more
Food Allergy and Food Intolerance
If someone reacts to a food, they may own a Food Hypersensitivity (FHS). FHS reactions involving the immune system are known as food allergy (FA), every other reactions are classified as food intolerances (FI).
Atopic Eczema (Dermatitis)
Eczema is a pattern of itchy skin rash consisting of tiny pink bumps that may join together producing ill-defined pink or red patches. There are numerous types of eczema – some own known causes. Dermatitis is the term used for eczema reactions that are caused by external agents/factors.
Atopic eczema is often referred to as “infantile” of childhood eczema because that is when it generally develops. Atopic eczema is generally associated with allergies (hayfever or asthma) in either the affected individuals or in their shut relatives. Read more
The allergic process can affect the skin producing 2 main types of rashes namely urticaria (hives, nettlerash, welts) or eczema (see atopic dermatitis section).
Urticaria is a red itchy bumpy rash that is often short-lived and can appear in various shapes and sizes anywhere on the is extremely common affecting 1 in 5 of the population at sometime in their some people urticaria is accompanied by large dramatic swellings commonly affecting lips, eyelids, tongue and hand called angioedema.
One of the most common medical complaints that we see in our office is dogs with skin infections, “hot spots”, or allergic dermatitis, also known as atopic (atopy) dermatitis.
Unlike people who react to allergens most commonly with nasal symptoms and/or hives, dogs react with skin and/or gastrointestinal problems. This is because there are a higher proportion of mast cells, which release histamines and other vasoactive substances in the face of an allergic challenge, in the skin of dogs.
These problems may range from poor jacket texture or hair length, to itching and chewing, to boiling spots and self-mutilation, gastrointestinal pain and discomfort, diarrhea, and flatulence. Allergies may also frolic a part in chronic ear infections. The most common causes of canine allergic dermatitis are flea allergy, food allergy, inhalant or contact allergy, and allergy to the normal bacterial flora and yeast organisms of the skin. To make matters more hard to diagnose and treat, thyroid disease may add to the problem as well.
Canine atopic dermatitis (allergic dermatitis, canine atopy) is an inherited predisposition to develop allergic symptoms following repeated exposure to some otherwise harmless substance, an “allergen”.
Most dogs start to show their allergic signs between 1 and 3 years of age. Due to the hereditary nature of the disease, several breeds, including Golden Retrievers, most terriers, Irish Setters, Lhasa Apsos, Dalmatians, Bulldogs, and Ancient English Sheep dogs are more commonly atopic, but numerous dogs, including mixed breed dogs can own atopic dermatitis. Atopic animals will generally rub, lick, chew, bite, or scratch at their feet, flanks, ears, armpits, or groin, causing patchy or inconsistent hair loss and reddening and thickening of the skin. The skin itself may be dry and crusty or oily depending upon the dog.
Dogs may also rub their face on the carpet; ear flaps may become red and boiling. Because the wax-producing glands of the ear overproduce as a response to the allergy, they get bacterial and yeast (Malassezia ) infections of the ear.
In order to overcome these frustrating symptoms, your veterinarian’s approach needs to be thorough and systematic. Shortcuts generally will not produce results and only add to owner frustration and canine discomfort.
Inhalant and Contact Allergies
Substances that can cause an allergic reaction in dogs are much the same as those that cause reactions in people including the pollens of grasses, trees and weeds, dust mites, and molds.
A clue to diagnosing these allergies is to glance at the timing of the reaction. Does it happen year round? This may be mold or dust. If the reaction is seasonal, pollens may be the culprit.
Numerous people don’t suspect food allergies as the cause of their dog’s itching because their pet has been fed the same food every its life and has just recently started having symptoms. However, animals can develop allergies to a substance over time, so this fact does not law out food allergies.
Another common misconception is that dogs are only sensitive to poor quality food. If the dog is allergic to an ingredient, it doesn’t matter whether it is in premium food or the most inexpensive brand on the market. One advantage to premium foods is that some avoid common fillers that are often implicated in allergic reactions.
This type of reaction generally is not to the flea itself, but rather to proteins in its saliva. Interestingly enough, the dogs most prone to this problem are not dogs who are constantly flea ridden, but those who are exposed only occasionally! A single bite can cause a reaction for five to seven days, so you don’t need a lot of fleas to own a miserable dog.
Bacterial hypersensitivity occurs when a dog’s immune system overreacts to the normal Staphylococcus (Staph) bacteria on its skin.
It appears that bacterial hypersensitivity in the dog is more likely to happen if other conditions such as hypothyroidism, inhalant allergy, and/or flea allergy are concurrently present. Bacterial hypersensitivity is diagnosed through bacterial culture and examination of a biopsy sample. Microscopically, there are certain unique changes in the blood vessels of the skin in bacterial hypersensitivity.
Rhinitis means inflammation of the lining of the nose Rhinitis is defined clinically as symptoms of runny nose itching, sneezing and nasal blockage (congestion).. Common causes of rhinitis are allergies which may be seasonal (‘hayfever’) or happen all-year-round (examples include allergy to home dust mite, cats, dogs and moulds).Infections which may be acute or chronic represent another common cause.
Rhinitis (whether due to allergic or other causes) is a risk factor for the development of asthma. Rhinitis is also implicated in otitis media with effusion and in sinusitis which should rightly be termed rhinosinusitis since sinus inflammation almost always involves the nasal passages as well.

Prescription drugs own been through a rigorous process of testing to ensure safety, despite this, a minority of individuals will develop side-effects.
Side- effects are termed “adverse drug reactions” by doctors and although the majority of adverse drug reactions are relatively minor and may even permit continuation with the drug, in some cases more severe symptoms can more
Numerous medicated shampoos own compounds in them that are aimed at soothing injured skin and calming inflammation. In addition, frequent bathing (weekly to every other week) of the dog can remove allergens from the hair jacket, which may contribute to skin allergy flare-ups.
The medicated baths we recommend are those that actually contain antimicrobial and antifungal agents as well as ingredients that permit the skin to be bathed on a more frequent basis without drying it out. Application of a rinse afterwards also helps to prevent drying out of the skin and hair coat.
Antihistamines can be used with excellent safety in dogs. About one third of owners report success with antihistamines. These medications tend to own a variable effect between dogs. For some allergic dogs, antihistamines work extremely well in controlling symptoms of allergic skin disease. For other dogs, extremely little effect is seen.
Therefore, a minimum of three diverse types of antihistamines should be tried before owners give up on this therapy. Examples of antihistamines commonly used for dogs include Benadryl, Chlortrimeton, Atarax, Claritin, Zyrtec, and Clemastine. However, antihistamines are considered to be worth trying in most cases since the side effects associated with antihistamines is low, and they are typically inexpensive medications.
Antibiotics and Antifungal Medications
Antibiotics are frequently needed to treat secondary skin infections.
Anti-fungal medications are frequently needed to treat secondary yeast infections.
For dogs with this problem, a strict flea control regime must be maintained. The best flea control options include the use of products such as Advantage, Revolution, Frontline, Comfortis, and Sentinel.
The Omega-3 and Omega-6 essential fatty acid supplements work by improving the overall health of the skin.
These fatty acids are natural anti-inflammatory and anti-oxidative agents. They reportedly are helpful in 20% of allergic dogs. My own experience puts this figure a little higher. They are certainly worth a attempt because they are not harmful and own virtually no side effects. Omega-3 fatty acids are found in fish oils and omega-6 fatty acids are derived from plants containing gamma-linolenic acid (GLA). These supplements are diverse from those sold to produce a glossy jacket. Products that contain both omega-3 and omega-6 fatty acids include Allergen Caps and Halo.
Allergies develop through exposure, so most hypoallergenic diets incorporate proteins and carbohydrates that your dog has never had before.
As mentioned previously, the quickest and best way to determine which foods your dog may or may not be allergic to is through diagnostic allergy testing. As dairy, beef, and wheat are responsible for 80% of food allergies in dogs, these items should be avoided. Novel protein sources used in hypoallergenic diets include venison, egg, duck, kangaroo, and types of fish not generally found in pet food. Carbohydrate sources include potatoes, peas, yams, sweet potatoes, and canned pumpkin.
Hydrolyzed protein diets are diets in which the protein source has been synthetically reduced to little fragments.
The theory behind feeding a hydrolyzed protein source is that the proteins in the food should be little enough that the allergic dog’s immune system will not recognize the protein fragments and will not mount an immune response resulting in an allergy.
Most pets with food allergies reply well when switched to a store-bought hypoallergenic diet, but occasionally an animal suffers from such extreme allergies that a homemade diet is the only option. In this case, the diet should be customized with the aid of a veterinarian.
Corticosteroids and Immunosuppressive Agents
Cortisone products such as prednisone, prednisolone, and dexamethasone reduce itching by reducing inflammation.
These medications are not without side effects, so they need to be used judiciously in treating skin allergies. Steroids should be considered only when the allergy season is short, the quantity of drug required is little, or to relieve a dog in extreme discomfort. Side effects can include increased thirst and appetite, increased need to urinate, and behavioral changes. Long-term use can result in diabetes and decreased resistance to infection. In some dogs, endless term, low-dose alternate day therapy is the only management protocol that successfully controls the atopic pet. This protocol should be used only as a final resort after every other methods own been exhausted to avoid the potential long-term complications of the medication.
Cyclosporine (Atopica) is a medication, which seems to be fairly effective at reducing the inflammation associated with skin allergies and calming the immune system of the affected dog.
However, the pricing of cyclosporine may be prohibitive for larger breed dogs.
Allergy shots are extremely safe, and numerous people own grand success with them; however, they are extremely slow to work. It may be six to twelve months before improvement is seen.
Once the allergens for the dog are identified, an appropriate immunotherapy is manufactured for that specific dog, and treatment can start. After the offending antigens are identified, then a mixture of these antigens can be formulated into a hyposensitizing injection. Depending on the type of agents used, these injections will be given over a period of weeks to months until the dog or cat develops immunity to the agents.
After initial protection, an occasional booster may own to be given.
If you know which substances your dog is allergic to, avoidance is the best method of control. Even if you are desensitizing the dog with allergy shots, it is best to avoid the allergen altogether. Molds can be reduced by using a dehumidifier or placing activated charcoal on top of the exposed dirt in your home plants. Dusts and pollens are best controlled by using an air cleaner with a HEPA filter. Air conditioning can also reduce circulating amounts of airborne allergens because windows are then kept closed.
Healthy skin and a normal hair jacket are the results of numerous factors, both external and internal.
There are several glands in the body responsible for the production of hormones that are vital for the regulation of other body functions as well as a normal skin surface and hair jacket. Hypothyroidism may result in poor skin and hair jacket, including hair loss or abnormal hair turnover, dull or brittle hair, altered pigmentation, and oily or dry skin. A blood test is a simplest and most direct way to tell if your dog is hypothyroid. Thyroid testing may include every or part of the following:
Baseline T4 Test or Entire T4 (TT4): This is the most common test.
Dogs with a failure of the thyroid gland will own a lowered level of the T4 hormone. However, there are other conditions that can cause the T4 to decrease, so if this test comes back positive for hypothyroidism your vet should recommend an additional blood test, either the T3 Test or the Baseline TSH test.
Baseline TSH Test: Measures the level of Thyroid Stimulating Hormone. In combination with the T4 or T3 test, it provides a more finish picture of the hormonal activity of your dog’s thyroid gland.
Free T4 by RIA (radio immunoassay): The Free T4 test using RIA techniques does not appear to be more or less precise than the above TT4 test.
Free T4 by ED (equilibrium dialysis): This test may provide more precise data on the level of T4 hormone in your dog’s bloodstream.
Baseline T3 Test: In combination with the T4 or TSH test, these two blood tests can give a clearer picture of the hormone levels found in the bloodstream.
This test is not dependable when used alone. The T3 Test should always be given in combination with one of the other blood tests.
TSH Response Test: In this test, the veterinarian takes an initial measurement of the thyroid hormones in your dog’s bloodstream and then injects Thyroid Stimulating Hormone (TSH) into the vein. After 6 hours, a blood sample is drawn and the level of T4 is checked. If your dog has hypothyroidism, the level of T4 will not increase even after the TSH is injected. This is an expensive test and is being used less often due to decreased production by the manufacturers.
Hypothyroidism is treated with a daily dose of synthetic thyroid hormone called thyroxine (levothyroxine).
Blood samples will need to be drawn periodically to assess the effectiveness of the dosage and make any adjustments necessary.
Successful management of the atopic, allergic dog is sometimes complicated and frustrating because multi-modal management is necessary in the majority of cases to control the allergic flare-ups. Proper diagnosis by a veterinarian and owner compliance and follow up care is essential to maximize the chances of curing or at least controlling the severely affected allergy patient.
After informed consent, subjects will be randomly assigned to ILIT group or placebo group in double-blind manner.
In both group, causal allergen or placebo will be injected into inguinal lymph node through guidance by ultrasonography three times with 4-week interval. In ILIT group, initial dose of allergen will be 1,fold diluted solution from maximal concentration of allergen extract for subcutaneous immunotherapy (Tyrosine S, Allergy Therapeutic, West Sussex, UK) in volume of ml. If skin is highly reactive in skin prick test, the initial dose will be fold dilution from maximal concentration where diameter of wheal is less than that of histamine. After the first dose, allergen concentration will be escalated 3-fold at second dose, and fold at third dose if there are no (or mild) local or systemic hypersensitivity reaction.
The allergen concentration will not change at second or third dose if there is moderate local or systemic reaction. The allergen concentration will decrease by 10 or fold from previous concentration or further injection will be held if there is severe local or systemic reaction after sufficient explanation and discussion with subjects.
The investigators will assess allergic rhinitis symptom score before and 4, 12 months after the initial treatment. Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) and Sino-Nasal Outcome Test (SNOT) will be used. Visual analogue scale (VAS) of symptoms including rhinorrhea, sneezing, nasal obstruction, postnasal drip, eye/nose/ear/palate itching, dyspnea, wheezing, chest discomfort as well as urticaria, angioedema, and itching on exposed skin during exposure to causal allergen in daily life will be also evaluated.
Skin prick test (SPT), intradermal test (IDT), blood sampling for serum entire immunoglobulin E (IgE), allergen-specific IgE, and allergen-specific immunoglobulin G4 (IgG4), nasal lavage for Th1, Th2, and Treg cytokines, and nasal provocation test (NPT) with Df and/or Dp allergen (in subjects whose AR symptoms are provoked by Df and/or Dp) will be also performed before and 4, 12 months after the initial treatment. In addition, the investigators evaluated the change of subjects’ recognition of causal allergens, their avoidance, and AIT during this study. Using VAS, subjects were requested to score the rate of agreement with "Allergen provokes allergic symptoms in daily life", "Allergen avoidance can reduce allergic symptoms", "Allergen-specific Immunotherapy (AIT) can reduce allergic symptoms", "I can pay 50, Korean Won (KRW)/month for allergen avoidance", "I can pay , KRW/month for allergen avoidance", "I can pay , KRW/month for allergen avoidance", "I can pay , KRW for each injection of ILIT", "I can pay , KRW for each injection of ILIT", "I can pay , KRW for each injection of ILIT" before and after SPT/IDT, after NPT, 4 months and 1 year after ILIT.
Adverse events will be recorded and graded according to Muller classification and Ring and Meissner classification.
It can be terribly upsetting to study that your kid is allergic to your family pet — but it’s not unusual.
Up to 30 percent of people with allergies own allergic reactions to cats and dogs, according to the Asthma and Allergy Foundation of America (AAFA).
Contrary to favorite belief, it’s not the pets’ hair that makes a kid sneeze and wheeze. It’s the proteins found in their urine, saliva, or pet dander, according to the AAFA. The proteins can stick to surfaces of walls, furniture, and clothing and stay there, at full strength, for a endless time. A pet also can bring other allergens, such as pollen, into your home.
“The first law of allergies is, if you’re allergic to something, stay away from it,” says Mark Holbreich, MD, an allergist and immunologist with Allergy and Asthma Consultants in Indianapolis.
When it’s your pet, though, that’s hard to do.
But if the allergies are severe, says the American Academy of Pediatrics, you may own to discover your pet a new home.
Symptoms of children’s pet allergies include a stuffy nose, itchy, watery eyes, and wheezing. Some people can own an asthma attack if their allergies flare, the AAFA says. If your kid experiences these symptoms after coming in contact with your dog or cat, own your kid tested.
“Testing is extremely important,” says Mervat Nassef, MD, a pediatric allergist and immunologist at NewYork-Presbyterian in New York City.
If you might own to give up your pet, you desire to be certain that your kid isn’t allergic to something else. “Other allergies can give you similar symptoms,” Dr. Nassef says.
It’s also significant to note that some animals may be more allergy-friendly than others. However, there’s no such thing as a hypoallergenic cat or dog, according to the American College of Asthma, Allergy & Immunology. “Small dogs that don’t shed produce less dander, but your kid still can be allergic to them,” Dr. Holbreich says.
Strategies to Reduce Pet Allergies
If your child’s allergies aren’t too severe, you may be capable to take some steps to reduce your child’s symptoms and hold your pet.
Keep pets out of the bedroom. Make your child’s room a pet-free zone and be certain to hold it clean. To hold the room pet dander- and pollen-free, install a high-efficiency air filter and air purifier. Remember to change the filters frequently.
Cover your child’s bed with additional protection. You can purchase dust mite covers for your child’s pillow, blanket, and mattress. This will also assist hold out dust mites, another potential allergy trigger, in addition to allergens love pet dander.
Go for hard surfaces.
Where you can, replace upholstered surfaces with non-fabric or easily washable materials. Pet dander sticks to upholstery, drapes, curtains, and carpeting more easily than it does to surfaces such as wood, vinyl, or tile. Plus, the latter are easier to clean. For this reason, you also shouldn’t let your allergic kid sleep with stuffed animals, Dr. Nassef adds. If you must own carpet in your child’s bedroom or elsewhere in your home, select a low-pile one and own it steam-cleaned regularly.
Bathe your pet weekly.
Weekly baths can significantly reduce the quantity of allergy-causing dander your pet sheds. If possible, enquire a non-allergic member of your household to bathe the pet and be certain to wash that person’s clothes afterward. Wearing gloves may also assist. Enquire your veterinarian to recommend the best soaps and shampoos. Caution: Bathing too frequently can own the opposite effect. It can dry your pet’s skin and cause the animal to shed more dander.
Teach your kid to wash his hands with soap and water after touching the pet. Washing helps prevent the spread of allergens to your child’s nose, eyes, and mouth — which is especially significant if your kid gets a rash from having been licked by your pet, Nassef says.
Talk to your allergist about treatment.
“Medications work for allergy symptoms regardless of the trigger — pollen, pet dander, etc.,” Nassef says. “But not every medications work equally well for every symptoms.” That’s why it’s significant to work with your doctor and tailor your child’s allergy medications to his or her symptoms.
Consult your veterinarian. Your veterinarian can recommend a diet for your pet that’s wealthy in vitamins and minerals, which can assist your pet’s skin retain its moisture and not shed as much. Love people, pets can benefit from omega-3 and omega-6 fatty acids, according to the Partnership for Animal Welfare in Greenbelt, Maryland.
Every family has to decide for themselves whether they can manage their children’s pet allergies with a cat or dog, Nassef says.
“The best solution for pet allergies is to not own a pet,» she says, «but numerous people consider pets part of their family and getting rid of the pet is out of the question.”
