InterpretationProvides information to help in interpretation of the test results

Detection of IgE antibodies in serum (Class 1 or greater) indicates an increased likelihood of allergic disease as opposed to other etiologies and defines the allergens that may be responsible for eliciting signs and symptoms.

The level of IgE antibodies in serum varies directly with the concentration of IgE antibodies expressed as a class score or kU/L.


Testimonials

I recently completed a course of Rhinolight as I suffer from allergic rhinitis, in specific with certain pollen and home dust mites.

My symptoms were fairly severe, with sneezing fits, a constantly runny nose and nighttime congestion that hampered my sleep.

Whilst the impact of the treatment wasn’t instantly noticeable (I didn’t own a ‘eureka’ moment), now that the course is over it’s clear that it’s made a massive difference to my day to day existence. I no longer need packets of tissues with me wherever I go, and I am sleeping through the night!

I really wish more people knew about Rhinolight as I genuinely believe it can be a gamechanger for those who suffer from allergies.

What Does FPIES Stand For?

FPIES is Food Protein-Induced Enterocolitis Syndrome. It is commonly pronounced «F-Pies», as in «apple pies», though some physicians may refer to it as FIES (pronounced «fees», considering food-protein as one word). Enterocolitis is inflammation involving both the little intestine and the colon (large intestine).

What are Some Common FPIES Triggers?

The most common FPIES triggers are traditional first foods, such as dairy and soy. Other common triggers are rice, oat, barley, green beans, peas, sweet potatoes, squash, chicken and turkey.

A reaction to one common food does not mean that every of the common foods will be an issue, but patients are often advised to proceed with caution with those foods. Note that while the above foods are the most prevalent, they are not exclusive triggers. Any food has the potential to trigger an FPIES reaction. Even trace amounts can cause a reaction.

What is a Typical FPIES Reaction?

As with every things, each kid is diverse, and the range, severity and duration of symptoms may vary from reaction to reaction.

What is the test for wheat allergy

Unlike traditional IgE-mediated allergies, FPIES reactions do not manifest with itching, hives, swelling, coughing or wheezing, etc. Symptoms typically only involve the gastrointestinal system, and other body organs are not involved. FPIES reactions almost always start with delayed onset vomiting (usually two hours after ingestion, sometimes as tardy as eight hours after). Symptoms can range from mild (an increase in reflux and several days of runny stools) to life threatening (shock).

In severe cases, after repeatedly vomiting, children often start vomiting bile. Commonly, diarrhea follows and can final up to several days. In the worst reactions (about 20% of the time), the kid has such severe vomiting and diarrhea that s/he rapidly becomes seriously dehydrated and may go into shock.

Frequently Asked Questions about Food Protein-Induced Enterocolitis Syndrome (FPIES)

What is FPIES?

FPIES is a non-IgE mediated immune reaction in the gastrointestinal system to one or more specific foods, commonly characterized by profuse vomiting and diarrhea.

FPIES is presumed to be cell mediated.

What is the test for wheat allergy

Poor growth may happen with continual ingestion. Upon removing the problem food(s), every FPIES symptoms subside. (Note: Having FPIES does not preclude one from having other allergies/intolerances with the food.) The most common FPIES triggers are cow’s milk (dairy) and soy. However, any food can cause an FPIES reaction, even those not commonly considered allergens, such as rice, oat and barley.

A kid with FPIES may experience what appears to be a severe stomach bug, but the «bug» only starts a couple hours after the offending food is given. Numerous FPIES parents own rushed their children to the ER, limp from extreme, repeated projectile vomiting, only to be told, «It’s the stomach flu.» However, the next time they feed their children the same solids, the dramatic symptoms return.

How Do I know If My Kid Has Outgrown FPIES?

Together with your child’s doctor, you should determine if/when it is likely that your kid may own outgrown any triggers.

Obviously, determining if a kid has outgrown a trigger is something that needs to be evaluated on a food-by-food basis. As stated earlier, APT testing may be an option to assess oral challenge readiness. Another factor for you and your doctor to consider is if your kid would physically be capable to handle a possible failed challenge.

When the time comes to orally challenge an FPIES trigger, most doctors familiar with FPIES will desire to schedule an in-office food challenge. Some doctors (especially those not practicing in a hospital clinic setting) may select to challenge in the hospital, with an IV already in put, in case of emergency.

Each doctor may own his or her own protocol, but an FPIES trigger is something you should definitely NOT challenge without discussing thoroughly with your doctor.

Be aware that if a kid passes the in-office portion of the challenge, it does not mean this food is automatically guaranteed «safe.» If a child’s delay in reaction is fairly short, a kid may fail an FPIES food challenge while still at the office/hospital. For those with longer reaction times, it may not be until later that day that symptoms manifest. Some may react up to three days later. Delay times may vary by food as well. If a kid has FPIES to multiple foods, one food may trigger symptoms within four hours; a diverse food may not trigger symptoms until six or eight hours after ingestion.

What Does IgE vs Cell Mediated Mean?

IgE stands for Immunoglobulin E.

It is a type of antibody, formed to protect the body from infection, that functions in allergic reactions. IgE-mediated reactions are considered immediate hypersensitivity immune system reactions, while cell mediated reactions are considered delayed hypersensitivity. Antibodies are not involved in cell mediated reactions. For the purpose of understanding FPIES, you can disregard every you know about IgE-mediated reactions.

Does FPIES Require Epinephrine?

Not generally, because epinephrine reverses IgE-mediated symptoms, and FPIES is not IgE-mediated. Based on the patient’s history, some doctors might prescribe epinephrine to reverse specific symptoms of shock (e.g., low blood pressure).

However, this is only prescribed in specific cases.

What is Shock and What are the Symptoms?

Shock is a life-threatening condition. Shock may develop as the result of sudden illness, injury, or bleeding. When the body cannot get enough blood to the vital organs, it goes into shock.

Signs of shock include:
Weakness, dizziness, and fainting.
Cool, pale, clammy skin.
Weak, quick pulse.
Shallow, quick breathing.
Low blood pressure.
Extreme thirst, nausea, or vomiting.
Confusion or anxiety.

How Do You Treat an FPIES Reaction?

Always follow your doctor’s emergency plan pertaining to your specific situation.

Rapid dehydration and shock are medical emergencies. If your kid is experiencing symptoms of FPIES or shock, immediately contact your local emergency services (9-1-1). If you are uncertain if your kid is in need of emergency services, contact 9-1-1 or your physician for guidance. The most critical treatment during an FPIES reaction is intravenous (IV) fluids, because of the risk and prevalence of dehydration. Children experiencing more severe symptoms may also need steroids and in-hospital monitoring. Mild reactions may be capable to be treated at home with oral electrolyte re-hydration (e.g., Pedialyte®).

How Do You Care for a Kid With FPIES?

Treatment varies, depending on the patient and his/her specific reactions.

Often, infants who own reacted to both dairy and soy formulas will be placed on hypoallergenic or elemental formula. Some children do well breastfeeding. Other children who own fewer triggers may just strictly avoid the offending food(s).

New foods are generally introduced extremely slowly, one food at a time, for an extended period of time per food. Some doctors recommend trialing a single food for up to three weeks before introducing another.

Because it’s a rare, but serious condition, in the event of an emergency, it is vital to get the correct treatment. Some doctors provide their patients with a letter containing a brief description of FPIES and its proper treatment.

In the event of a reaction, this letter can be taken to the ER with the child.

When Do FPIES Reactions Occur?

FPIES reactions often show up in the first weeks or months of life, or at an older age for the exclusively breastfed kid. Reactions generally happen upon introducing first solid foods, such as baby cereals or formulas, which are typically made with dairy or soy. (Infant formulas are considered solids for FPIES purposes.) While a kid may own allergies and intolerances to food proteins they are exposed to through breastmilk, FPIES reactions generally don’t happen from breastmilk, regardless of the mother’s diet.

An FPIES reaction typically takes put when the kid has directly ingested the trigger food(s).

How is FPIES Diagnosed?

FPIES is hard to diagnose, unless the reaction has happened more than once, as it is diagnosed by symptom presentation. Typically, foods that trigger FPIES reactions are negative with standard skin and blood allergy tests (SPT, RAST) because they glance for IgE-mediated responses. However, as stated before, FPIES is not IgE-mediated.

Atopy patch testing (APT) is being studied for its effectiveness in diagnosing FPIES, as well as predicting if the problem food is no longer a trigger.

Thus, the outcome of APT may determine if the kid is a potential candidate for an oral food challenge (OFC). APT involves placing the trigger food in a metal cap, which is left on the skin for 48 hours. The skin is then watched for symptoms in the following days after removal. Please consult your child’s doctor to discuss if APT is indicated in your situation.

Is FPIES A Lifelong Condition?

Typically, no. Numerous children outgrow FPIES by about age three.

Note, however, that the time varies per individual and the offending food, so statistics are a guide, but not an absolute. In one study, 100% of children with FPIES reactions to barley had outgrown and were tolerating barley by age three. However, only 40% of those with FPIES to rice, and 60% to dairy tolerated it by the same age.

How is FPIES Diverse From MSPI, MSPIES, MPIES, Etc.?

MPIES (milk-protein induced enterocolitis syndrome) is FPIES to cow’s milk only. MSPIES (milk- and soy-protein induced enterocolitis syndrome) is FPIES to milk and soy. Some doctors do create these subdivisions, while others declare that milk and soy are simply the two most common FPIES triggers and give the diagnosis of «FPIES to milk and/or soy.»

MSPI is milk and soy protein intolerance.

Symptoms are those of allergic colitis and can include colic, vomiting, diarrhea and blood in stools. These reactions are not as severe or immediate as an FPIES reaction.

Useful ForSuggests clinical disorders or settings where the test may be helpful

Establishing a diagnosis of an allergy to codfish, cow’s milk, egg white, peanut, soybean, and wheat

Defining the allergen responsible for eliciting signs and symptoms

Identifying allergens:

-Responsible for allergic disease and/or anaphylactic episode

-To confirm sensitization prior to beginning immunotherapy

-To investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens

Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists, or in patients in whom the medical management does not depend upon identification of allergen specificity.


Clinical InformationDiscusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

Clinical manifestations of immediate hypersensitivity (allergic) diseases are caused by the release of proinflammatory mediators (histamine, leukotrienes, and prostaglandins) from immunoglobulin E (IgE)-sensitized effector cells (mast cells and basophils) when cell-bound IgE antibodies interact with allergen.

In vitro serum testing for IgE antibodies provides an indication of the immune response to allergen(s) that may be associated with allergic disease.

The allergens chosen for testing often depend upon the age of the patient, history of allergen exposure, season of the year, and clinical manifestations.

In individuals predisposed to develop allergic disease(s), the sequence of sensitization and clinical manifestations proceed as follows: eczema and respiratory disease (rhinitis and bronchospasm) in infants and children less than 5 years due to food sensitivity (milk, egg, soy, and wheat proteins) followed by respiratory disease (rhinitis and asthma) in older children and adults due to sensitivity to inhalant allergens (dust mite, mold, and pollen inhalants).


Testing AlgorithmDelineates situations when tests are added to the initial order.

This includes reflex and additional tests.

Includes testing for codfish, cow’s milk, egg white, peanut, soybean, and wheat allergen.


CautionsDiscusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

Some individuals with clinically insignificant sensitivity to allergens may own measurable levels of IgE antibodies in serum, and results must be interpreted in the clinical context.

False-positive results for IgE antibodies may happen in patients with markedly elevated serum IgE (>2500 kU/L) due to nonspecific binding to allergen solid phases.
