Disorders Of The Immune System
Overactivity of the immune system can take many forms. In allergic diseases the immune system makes an excessive response to proteins in substances . In autoimmune diseases the immune system mounts a response against normal components of the body.
- Allergic diseases are extremely common and include food, drug or insect allergy, hay fever , sinus disease, asthma, hives and eczema . Anaphylaxis is the most severe type of allergic reaction and is potentially life-threatening. For fast facts about allergic diseases go to www.allergy.org.au/patients/fast-facts
- Autoimmune diseases range from common to rare. These include multiple sclerosis, autoimmune thyroid disease, type 1 diabetes, systemic lupus erythematosus , rheumatoid arthritis and vasculitis. For Fast Facts about autoimmune diseases go to www.allergy.org.au/patients/fast-facts/autoimmune-diseases
Underactivity of the immune system, also called immunodeficiency, can be inherited, acquired as a result of medical treatment or caused by another disease. Immunodeficiency predisposes people to infections and/or swellings and can be life threatening in severe cases.
- Acquired immunodeficiencies include AIDS , that is due to human immunodeficiency virus . PIDs are different to AIDS, as PID are caused by defects in the genes that control the immune system, and may be inherited.

What Causes An Overgrowth Of Candida
Candida becomes problematic when there is too much Candida in relation to our bodys good bacteria. This causes Candida to overpower our good bacteria, which can lead to a variety of digestive disorders like, Increased Intestinal Permeability, commonly known as leaky gut. Since Candida is normally found in our body, it is important to know what really triggers candida to overpower or weaken their bacteria counterpart. Some of the most common triggers includes antibiotics, oral contraceptives, vaginal douching, Cesarean deliveries and stress.
Antibiotics
-
Although, it was previously thought that recurrent rounds of antibiotics was to blame for alternating our gut bacteria, a new study suggests that one course of antibiotics can alter the gut mirobiome for up to a year! Antibiotics, definitely have their place in life-saving medicine, however, it is important to be aware of when antibiotics are absolutely necessary and when we could probably go without them. Patients suffering with acne, of example, are often prescribed months of antibiotics, when in relatively this is likely a disadvantage when it comes to treating acne.

What Is The Treatment For High Eosinophils
Treatment for high eosinophils depends on the cause of the condition. If the eosinophilia is related to an allergic reaction, the most simple fix is to avoid the drug, food, or other substance which is causing this reaction.
When medication takes away the job of the eosinophils, this helps the body stop overproducing them. Sometimes medications such as anti-infectives, anti-inflammatories, or corticosteroids may relieve high eosinophil count.

Deterrence And Patient Education
Leukocytosis is a common laboratory finding that may be transient or chronic. It often resolves with little to no treatment but should be properly assessed by a clinician to evaluate for the cause of the inflammatory response. More laboratory tests and imaging may be a part of the work-up for the cause of leukocytosis. Routine and regular follow-up with a primary care clinician is crucial for any patient’s healthcare.
How Is Eosinophilia Treated
Treatment depends on the cause of the condition. Treatments might include stopping certain medications , avoiding certain foods , or taking an anti-infective or anti-inflammatory medication. Treatments that target eosinophils in asthma specifically have been approved by the Food & Drug Administration and are being used in the clinic, while treatments for other eosinophil-mediated conditions are under further investigation.

Patients who qualify can participate in clinical trials, allowing them access to the latest therapies available.
Malignant Causes Of Leukocytosis
âLeukocytosis can also signal malignant disorders, especially leukemias or other blood cancers. Doctors look at several factors when considering this diagnosis.â
Symptoms. Fever, night sweats, and weight loss are three symptoms that suggest a malignant cause of leukocytosis. Doctors also look for evidence of bleeding or easy bruising. Fatigue may be present.
Physical examination. Doctors check for swollen lymph nodes, an enlarged liver, and an enlarged spleen. They also look for petechiae, pinpoint spots caused by bleeding under the skin.â
Lab results. Blood cancers are the typical cause of white blood counts over 30,000 per microliter. Some of the cells may be immature. Other counts, such as red blood cells and platelets, may be low.

Mouth And Throat Allergy Syndrome
Some people get a type of allergic reaction to certain foods that only causes symptoms in the mouth and throat. It tends to cause itching, tingling, and swelling of the mouth, lips and throat. Fresh fruit, vegetables and nuts commonly cause this. It can be confused with an extreme form of allergic reaction .
It has the potential to be serious, as swelling in the mouth and throat can affect the ability to breathe however, this is rare. The symptoms start within minutes of eating and tend to settle completely within an hour. Often if you have this condition, you can eat cooked versions of these foods with no problem, but the raw food gives you symptoms. This is because the proteins causing the allergic reaction are destroyed by the cooking process. Oral allergy syndrome usually affects people who get hay fever, and may also be called pollen food syndrome.
Note: an ambulance should be called immediately if you feel faint, have difficulty breathing or feel like your throat is closing up.
Why Allergy Blood Tests Are Done
Allergy skin testing is the preferred method, but in some cases blood testing may be ordered.
Allergy blood testing is recommended if you:
- Are using a medicine known to interfere with test results and cannot stop taking it for a few days this would include antihistamines, steroids, and certain antidepressants.
- Cannot tolerate the many needle scratches required for skin testing
- Have an unstable heart condition
- Have poorly controlled asthma
- Have severe eczema, dermatitis, psoriasis, or another severe skin condition
- Might have an extreme reaction during skin testing or have a history of life-threatening allergic reaction called anaphylaxis
Your doctor may also order blood testing to determine how well your allergy treatments are working. Blood testing may also show whether you have outgrown an allergy.

Diagnosis Of Overproduction Of White Blood Cells In Cats
The veterinarian will need to know the cat’s health history, when the symptoms first began and a detailed list of the symptoms. The veterinarian will physically examine the cat, listening to its heart and lungs and feeling for swollen lymph nodes and masses in its body.
Several labs will be performed in order to identify the condition and rule out other conditions that may present with similar symptoms. These labs include a complete blood count, a biochemical blood profile, a cytochemical staining, a fecal flotation test and a urinalysis. These tests will typically show a high number of white blood cells, anemia, and organ dysfunction in the affected organs.
A bone marrow aspiration will also be performed. The cat will be given anesthesia while the veterinarian removes a small amount of the bone marrow in order to determine what is causing the high levels of white blood cells to occur. Because blood cells are made from cells in the bone marrow, the aspiration is an important test to rule out similar conditions. The veterinarian may also biopsy the lymph nodes, spleen, liver or intestines. The biopsy can be particularly helpful in distinguishing the condition from eosinophilic leukemia. During the biopsy, the cat will be placed under general anesthesia while a small sample of tissue is removed from the organs.
How Is The Test Used
The white blood cell count is used as part of a full complete blood count to:
- Screen for a wide range of diseases and conditions
- Help diagnose an infection or inflammatory process or other diseases that affect the number of WBCs, such as allergies, leukemia or immune disorders, to name a few.
- Monitor the progression of conditions such as those named above
- Monitor the bodys response to various treatments and/or to monitor bone marrow function some treatments, such as radiation and chemotherapy, are known to affect white cells and may be monitored using WBC counts.
A WBC count can be used to detect is a disease or condition affecting white blood cells, but it cannot determine the underlying cause. Several other tests may be done help make a diagnosis, such as a WBC differential, a blood smear review, or in severe conditions, a bone marrow examination. A differential may indicate which type of WBC is low or high while a blood smear and/or bone marrow biopsy can reveal the presence of abnormal and/or immature WBCs.

When Is It Ordered
A WBC count is normally ordered as part of the complete blood count , which may be performed when you have a routine health examination. The test may be done when you have general signs and symptoms of an infection and/or inflammation, such as:
- Fever, chills
- Leukemia: Bone marrow biopsy, immunophenotyping , chromosome analysis
What Is Being Tested

Blood is made up of three main types of cells suspended in fluid called plasma. In addition to WBCs, there are red blood cells and platelets. All of these cells are made in the bone marrow and are released into the blood to circulate.
There are five types of WBCs, and each has a different function:

Eosinophils Mast Cells Basophils: Friends Foes Or Both
Eosinophils, mast cells, and basophils all were first recognized and described by Paul Ehrlich in the late 19th century. Since then, it has become clear that these three cell types have much more in common than their recognition by the same scientist. All three cell are involved in the pathogenesis of allergic disease. This is a consequence of the receptors expressed on their surface and their arsenal of powerful immunologically active mediators that are released upon activation. These mediators can either be preformed and released within seconds to minutes after activation, or de novo synthesized and released minutes to hours to days after activation. While mature mast cells do not occur in blood, eosinophils are found both circulating in blood and in hematopietic and lymphatic organs, such as the bone marrow, spleen, lymph nodes and thymus. Basophils are only found in blood in healthy individuals , but are known to be rapidly recruited to inflamed tissues, where they can reach high densities and play non-redundant roles. Mast cells are resident in vascularized tissues throughout the body and are particularly prominent within tissues that interface the external environment.
The pathological roles of eosinophils, mast cells, and basophils in allergy are either directly or indirectly linked with the presence of allergen-specific IgE in allergic individuals.

Elevated White Blood Cell Count: Causes Treatments And More
Jenny Hills, Nutritionist and Medical Writer Health
Doctors test for white blood cell count to measure the number of white blood cells in your body. This blood test is usually done as part of a standard complete blood count test. White blood cells are also called leukocytes and they are part of your immune system. They attack germs, bacteria, and microbes that can cause infections or inflammation. White blood cells can be divided into five main types: neutrophils, lymphocytes, monocytes, eosinophils, and basophils.
Usually, blood test results show elevated white blood cell count if you are fighting an infection or have an inflammatory condition. Pregnancy can also cause a high or slightly elevated white blood cell count. However, other factors like stress, smoking, or allergies can elevate your white blood cell count. Doctors also check for abnormal WBC levels if they suspect an autoimmune condition, blood disorder, or problem with your immune system.
There are not always obvious symptoms if your white blood cell count is outside the normal range. A high white blood cell count could be accompanied by symptoms of a viral infection or allergic reaction like fatigue, runny nose, coughing, or digestive upset. There are also some medical conditions that cause your white blood cell count to drop lower than normal.
Viral Or Bacterial Infection
The most common cause of higher than normal white blood cells is because your body is fighting an infection. The presence of germs, bacteria, or viruses signal to your body to produce more WBCs to destroy the pathogens.
For example, the Scandinavian Journal of Infectious Diseases reports that higher than normal levels of lymphocytes are seen in most viral and bacterial respiratory infections.5
The Journal of Cytology also reported that white blood cell count, especially neutrophils, becomes elevated in fungal infections. For example, if a person shows signs of a candida infection, their WBC count will usually be above the normal range.6

Causes Of Overproduction Of White Blood Cells In Cats
It is not known what causes hypereosinophilic syndrome to occur. Researchers believe that it may be caused by an overreaction to an unidentified antigen. This antigenic stimulus may arise from two different viral strains, prompting the production of white blood cells. Cats who have had eosinophilic enteritis, a disease that causes inflammation in the small intestine, may be predisposed to hypereosinophilic syndrome.
Why Do I Need A White Blood Count
You may need this test if you have signs of an infection, inflammation, or autoimmune disease. Symptoms of infection include:
Symptoms of inflammation and autoimmune diseases will be different, depending on the area of inflammation and type of disease.
You may also need this test if you have a disease that weakens your immune system or are taking medicine that lowers your immune response. If the test shows your white blood count is getting too low, your provider may be able to adjust your treatment.
Your newborn or older child may also be tested as part of a routine screening, or if they have symptoms of a white blood cell disorder.

What Are The Side Effects Of High White Blood Cells
A high white blood cell count may indicate that the immune system is working to destroy an infection.Individuals with idiopathic hypereosinophilic syndrome may experience symptoms such as: weight loss. fevers. night sweats. fatigue. coughing. difficulty breathing. abdominal pain. vomiting and diarrhea.
What Is A Food Intolerance
A food intolerance is not the same as a food allergy. Many people incorrectly use the words interchangeably. A food allergy is the body’s immune system reacting abnormally to specific foods. No allergic reaction takes place with a food intolerance.
People with a food intolerance may have digestive symptoms such as diarrhoea, bloating and stomach cramps. These are quite common symptoms anyway. For example, other conditions, such as irritable bowel syndrome , can also cause these symptoms.
In food intolerance, the symptoms can be caused by various problems. Although the immune system is not involved, it does not mean that symptoms of food intolerance are unimportant or mild in nature. Food intolerance can cause considerable problems and significant symptoms.
Some examples are:
Also, many people incorrectly assume symptoms they have are due to food intolerances when in fact their symptoms are not due to food. Consequently, people commonly cut things out of their diet that they believe to be the cause of their problems. In itself this can lead to further problems.
In summary, food intolerance often ends up being a rather vague term which is sometimes difficult to clarify.

Allergy Blood Test Results
A positive result means allergy-specific antibodies were detected in your blood. This is usually a sign of an allergy.
The blood test will reveal what exactly you are allergic to. However, you can test positive for something but never have had an allergic reaction to it.
A negative result means you probably do not have a true allergy. That means your immune system probably does not respond to the allergen tested. However, it is possible to have a normal allergy blood test result and still have an allergy.
Allergy blood test results should be interpreted with caution by an allergy specialist. Your doctor will also consider your symptoms and medical history when diagnosing a specific allergy.
