Frequently Asked Questions about Food Protein-Induced Enterocolitis Syndrome (FPIES)
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).
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. 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.
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.
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 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. 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.
What Are the Signs & Symptoms of a Milk Allergy?
In children who show symptoms shortly after they own milk, an allergic reaction can cause:
- throat tightness
- trouble breathing
- stomach upset
- itchy, watery, or swollen eyes
- a drop in blood pressure causing lightheadedness or loss of consciousness
The severity of allergic reactions to milk can vary.
The same kid can react differently with each exposure. This means that even though one reaction was mild, the next could be more severe and even life-threatening.
Children also can have:
- an intolerance to milk in which symptoms — such as loose stools, blood in the stool, refusal to eat, or irritability or colic — appear hours to days later
- lactose intolerance, which is when the body has trouble digesting milk
If you’re not certain if your kid has an intolerance versus an allergy, talk to your doctor.
What Is a Milk Allergy?
When a baby is allergic to milk, it means that his or herimmune system, which normally fights infections, overreacts to proteins in cow’s milk.
Every time the kid has milk, the body thinks these proteins are harmful invaders and works hard to fight them. This causes an allergic reaction in which the body releases chemicals love .
Cow’s milk is in most baby formulas.
Babies with a milk allergy often show their first symptoms days to weeks after they first get cow milk-based formula. Breastfed infants own a lower risk of having a milk allergy than formula-fed babies.
People of any age can own a milk allergy, but it’s more common in young children. Numerous kids outgrow it, but some don’t.
If your baby has a milk allergy, hold two epinephrine auto-injectors on hand in case of a severe reaction (called anaphylaxis). An epinephrine auto-injector is an easy-to-use prescription medicine that comes in a container about the size of a large pen. Your doctor will show you how to use it.
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.
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.

Colonization with the Staphylococcus aureus bacterium was significantly and independently associated with food allergy in young children with eczema enrolled in a pivotal peanut allergy prevention study.
is a marker for severe eczema, and early eczema is a widely recognized risk factor for developing food allergies in young children.
But the findings from the Learning Early About Peanut Allergy (LEAP) study cohort show that even after controlling for eczema severity, skin S.
aureus positivity was associated with an increased risk for developing allergies to peanuts, eggs, and cow’s milk.
S. aureus colonization was also associated with persistent egg allergy until at least age 5 or 6 years in the LEAP cohort analysis in the Journal of Allergy and Clinical Immunology.
The lead researcher, Olympia Tsilochristou, MD, of Kings College London, said in a press statement that the findings could assist explain why young children with eczema own a extremely high risk for developing food allergies.
While the exact mechanisms linking the two are not known, «our results propose that the bacteria Staphylococcus aureus could be an significant factor contributing to this outcome,» she said.
The findings also propose that S. aureus colonization may inhibit peanut tolerance among at-risk infants when peanuts are introduced extremely early in life.
Among the nine participants in the peanut-consumption arm of the study (i.e., no peanut allergy at baseline) who had confirmed peanut allergy at 60 and 72 months, every but one were colonized with S.
aureus at one or more LEAP study visits.
«The fact that S. aureus was associated with greater risk of peanut allergy among peanut consumers but not peanut avoiders further suggests that peanut consumption was less effective in the prevention of peanut allergy among participants with S. aureus compared with those with no S. aureus,» the researchers wrote.
The LEAP study enrolled infants ages months with severe eczema, egg allergy, or both. The babies were randomized to therapeutic peanut consumption or peanut avoidance, and every had eczema clinical evaluation and culture of skin and nasal swabs at baseline.
The follow-up LEAP-On study assessed the children at age 72 months, after 12 months of peanut avoidance in both groups.
Skin and nasal swabs were obtained at baseline and at age 12, 30, and 60 months.
A entire of % of the participants had some form of S. aureus colonization (% skin and % nasal) on at least one LEAP study visit, with most having just one positive test result. The greatest rates of colonization were recorded at months of age.
S. aureus colonization was significantly associated with eczema severity, along with hen’s egg white and peanut specific immunoglobulin (sIg)E production at any LEAP visit. But even after controlling for eczema severity, hen’s egg white and peanut sIgE levels at each LEAP and LEAP-On visit were significantly associated with skin S.
aureus positivity, the team noted.
«This relationship was even stronger when we looked into high-level hen’s egg white and peanut sIgE production,» the researchers wrote. «Similar findings were noted for cow’s milk, where high-level sIgE production to milk at 30, 60, and 72 months of age was related to any skin S. aureus colonization. Together, these data propose that S. aureus is associated with hen’s egg, peanut, and cow’s milk allergy.»
In the LEAP study, extremely early peanut consumption was found to reduce the risk of peanut allergy at 60 months in infants at high risk for developing the allergy, but infants in the consumption arm of the study with S.
aureus colonization were approximately seven and four times more likely to own confirmed peanut allergy at 60 and 72 months, the team said.
Study strengths, Tsilochristou and co-authors noted, included the rigorous design; a limitation was the reliance on bacteriological culture to identify S. aureus colonization rather than using DNA-based testing.
«S. aureus has been implicated in the development and severity of atopic diseases, namely eczema, allergic rhinitis, and asthma; our findings extend these observations to the development of food allergy independent of eczema severity,» the investigators concluded.
«The role of S.
aureus as a potential environmental factor should be considered in future interventions aimed at inducing and maintaining tolerance to food allergens in eczematous infants. Further prospective longitudinal studies measuring S. aureus with more advanced techniques and interventional studies eradicating S. aureus in early infancy will assist elucidate its role in the development of eczema or food allergy,» the team wrote.
The reported prevalence of CMA varies but it is estimated that it is between % of infants in the first year of life.
The treatment is the finish exclusion of cow’s milk from the infant’s diet.
CMA presents with a variety of clinical symptoms and the reactions may either be non-IgE mediated or IgE mediated. Non- IgE mediated reactions generally present as delayed, with mild to moderate symptoms.
IgE mediated reactions result in immediate and potentially severe symptoms e.g. acute angioedema or urticaria (see table ) needing further investigation.
In numerous infants the diagnosis of cow’s milk allergy has not been confirmed and the baby may remain on the specialist formula and a cow’s milk free diet for longer than necessary, which might own nutritional and social implications. CMA is confirmed in only one in three children presenting with possible symptoms, using strict, well defined elimination and open challenge criteria.
There are no validated laboratory or skin tests for the diagnosis of non-IgE CMA.
The diagnosis can only be confirmed by the planned avoidance of cow’s milk and cow’s milk containing foods followed by re-introduction.

How Is a Milk Allergy Diagnosed?
If you ponder your baby is allergic to milk, call your baby’s doctor. He or she will enquire you questions and talk to you about what’s going on. After the doctor examines your baby, some stool tests and blood tests might be ordered. The doctor may refer you to an allergist (a doctor who specializes in treating allergies).
The allergist might do skin testing.
In skin testing, the doctor or nurse will put a tiny bit of milk protein on the skin, then make a little scratch on the skin. If your kid reacts to the allergen, the skin will swell a little in that area love an insect bite.
If the allergist finds that your baby is at risk for a serious allergic reaction, epinephrine auto-injectors will be prescribed.
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, % 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 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 (). If you are uncertain if your kid is in need of emergency services, contact 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®).
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 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.
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.
If Your Kid Has an Allergic Reaction
If your kid has symptoms of an allergic reaction, follow the food allergy action plan your doctor gave you.
If your kid has symptoms of a serious reaction (like swelling of the mouth or throat or difficulty breathing, or symptoms involving two diverse parts of the body, love hives with vomiting):
- Give the epinephrine auto-injector correct away.
Every second counts in an allergic reaction.
- Then,call or take your kid to the emergency room. Your kid needs to be under medical supervision because, even if the worst seems to own passed, a second wave of serious symptoms can happen.
Avoiding a Milk Allergy Reaction
If You’re Formula Feeding
If you’re formula feeding, your doctor may advise you to switch to an extensively hydrolyzed formulaor an amino acid-based formula in which the proteins are broken below into particles so that the formula is less likely to trigger an allergic reaction.
You also might see "partially hydrolyzed" formulas, but these aren’t truly hypoallergenic and can lead to a significant allergic reaction.
If you’re concerned about a milk allergy, it’s always best to talk with your child’s doctor and work together to select a formula that’s safe for your baby.
Do not attempt to make your own formula.
Commercial formulas are approved by the U.S. Food and Drug istration (FDA) and created through a extremely specialized process that cannot be duplicated at home. Other types of milk that might be safe for an older kid with a milk allergyare not safe for infants.
If you own any questions or concerns, talk with your child’s doctor.

Oral immunotherapy for cow's milk allergy.
OBJECTIVE:Cow's milk allergy (CMA) is common in children and may lead to severe systemic reactions.
Avoidance of the ingestion of cow milk is the only effective approach, but this does not exclude the inadvertent or accidental ingestion, or the assumption of milk hidden in other foods. As no pharmacological treatment is available, specific desensitization has been considered an attractive strategy.
RESULTS:In the final years, several trials of oral desensitization to cow milk, with diverse protocols, were published. Overall the results were favourable and demonstrated the achievement of a full tolerance in a high percentage of children. Mild side effects that can be easily managed by slowing the desensitization were reported frequently.
The discontinuation of the procedure was necessary in less than 20% of children, on average, due to severe side effects.
CONCLUSIONS:Oral immunotherapy (oral desensitization) seems to be a promising treatment strategy for cow milk allergy in children that can be applied also to other foods such as eggs or peanuts.
