Diagnosis • History • Testing if applicable • Food elimination followed by

Food reintroduction/trial or “challenge” phase

Management phase

IgE mediated cow’s milk allergies

History • Dietary focused allergy history • Symptoms within 2 hours of

consumption • Foods 14 major allergens

Skypala et al. Clin Exp Allergy 2015

Children’s Healthcare of Atlanta | Emory University

Food Allergy Evaluation: History Is Critical; Ask Specific Questions

• Suspected culprit food protein (i.e., egg vs. red Gatorade): – Which was it? One of the “big 8?” – What form did they eat? Had they eaten it before? – How much? – Have they eaten it again - ask about other forms - since the episode?

• What happened then? – Timing & sequence of symptoms?

• Yes: Hives, swelling, abd pain, vomiting, wheezing/coughing, significant AD flare, anaphylaxis within 15 – 60 (up to 120) min

• No: headaches, fatigue, flat nonpruritic red rash on face or bottom; significant delay between exposure & sx

– Did the episode require treatment?


What about a young child who has never eaten the food?

What if the patient has atopic dermatitis?


Decision Points

Sampson HA Allergy 2005 (60): 19-24

*** These numbers predict likelihood of symptoms, not severity, and were studied in patients with a high pretest probability of disease ***

Note: not Class IV


Diagnostic Limitations

• Most direct-to-consumer testing is worthless • Conventional tests are often misinterpreted • Correctly interpreted tests still have significant limitations:

– probabilistic, not diagnostic – cannot determine alone if patient is allergic or tolerant – cannot determine how much food it might take to react – cannot tell “severity” / offer assessment risk

• Every patient is thus assumed to be at high risk for a life-threatening reaction – Important downstream effects for families, communities, schools, etc.

Chafen JJ et al JAMA 2010


Key Diagnostic Points

1. Skin & blood tests are only markers of exposure, not disease (TB) 2. A convincing history of symptoms after ingestion is key

– If the child can eat the food sometimes, allergy is not likely

3. If a prick skin test, done correctly, is negative, allergy is not likely – NPV > 90%

4. In general, strongly positive tests might be helpful – Prick test > 8-10 mm or IgE level above “decision point”

5. Indeterminate test results are common and can be confusing, especially in certain settings (e.g., AD, no/poor history)

6. If uncertain, the gold standard for diagnosis is oral challenge

Case 1

• Case scenario: Emily • You are seeing a 6-month old girl who had an infant cereal containing

milk, which her day care attendant gave to her • She developed wide-spread urticaria, breathing difficulties,

angioedema and was rushed to the ER (A&E). • Mother still breast feeding, has not given Emily any milk containing

food, but mother has been consuming milk containing food while breast feeding and Emily has not had any problems

History

• Breast fed with maternal consumption of cow’s milk: Ice cream, yogurt, cheese, cake, cookies, butter

• Not tried infant formula • Eaten some fruit and

vegetable purees • Eaten baby rice • Not tried yogurt • Infant cereal:

SPT results as follow:

• Histamine 4 mm

• Saline 0 mm

• Milk 8 mm

Do you think she has a cow’s milk allergy?

• Yes • No • Need further testing: Specific IgE tests • Need further testing: component resolved diagnostic testing

Allergy testing should only be carried out if there is clinical suspicion of cow's milk allergy as it has poor predictive value as a screening tool. Luyt et al. Clin Exp Allergy 2014

Specific IgE results

• Milk specific IgE 12 kuA/L • Milk specific casein 10 kuA/L • Milk specific beta-lactaglobulin 6 kUA/L

Mukkada 2010; Furuta 2018 18

Are you going to perform a food challenge?

• No • Yes to cow’s milk • Yes to baked milk

Can babies react to cow’s milk allergens via breastmilk? 1. No

2. Yes

3. Depends on the type of cow’s milk allergy

20

Symptoms while breastfeeding

Rationale and substantiation: • Host et al. 1988:

• Only 1 prospective study • 0.5% presented while on breast milk only (out of 2.2%)

• Some infants with CMA can react to residual β-lactoglobulin transferring to breast milk Breast milk: 0.9-150ug/l (median 4.2ug/l) EHFs: 0.84 -14.5ug/l

• However limited evidence available to substantiate this as first line formula if breast milk not available

Breast milk is the preferred nutrition for infants with CMA - Infant should continue taking breast milk while, if advised, mom avoids dairy under medical supervision

Presentation or condition

NIAID US guidelines

DRACMA international guidelines

ESPGHAN European guidelines

BSACI guidelines

Breast-feeding with ongoing symptoms (already on maternal elimination diet) or requiring formula, e.g. to supplement

EHF or AAF “Prior to initiating an oral food challenge… until the allergic [sic]

food is identified”

Not specified EHF or AAF

“In breast-fed infants with severe symptoms …it is common

practice in many countries to use AAF for diagnostic elimination...”

AAF if symptoms when

exclusively breastfed

Symptoms while breastfeeding

Limited data suggest an AAF can be used first line if formula is needed to supplement or replace breast milk because intolerance to eHF may occur

First choices for CMA and related conditions ONLY when formula is needed

Nowak-Wegrzyn. JACI In Pract. 2018

If baked milk tolerant: How much baked milk • Know exactly how much milk the patient has tolerated • THEN you can provide specific guidance For instance published recipes provide • No more than 1/6th cup of milk per serving (1.3 g protein)

• For example: I cup of milk in a recipe that yields 6 servings

Leonard, Caubet, Kim, Groetch, Nowak-Wegrzyn. JACI In Pract. 2015

Caution: Read Product labels carefully

1. Rule: Milk or egg ingredient is the 3rd ingredient or further down the list of ingredients. Although there is no way to critically evaluate this practice, it has been used effectively.

2. Final cooking time will depend on the size of the finished product- most published reports suggest 30 min for 350 degrees

3. All baked products must be baked throughout and not wet or soggy in the middle.

Leonard et al. 2015

Non-IgE mediated cow’s milk allergy

Food protein induced enterocolitis syndrome

History

• The NIAID Food Allergy Guidelines recommend using the medical history and OFC to establish a diagnosis of FPIES

• When history indicates that infants or children have experienced hypotensive episodes or multiple reactions to the same food, a diagnosis may be based on a convincing history and absence of symptoms when the causative food is eliminated from the diet.

• Boyce et al. Journal Allergy Clin Immunology 2010 • Nowak-Wegrzyn et al. Journal Allergy Clin Immunology 2017

Skin prick tests/Specific

IgE tests

• Food-specific IgE and skin prick testing may be performed to provide complete evaluation for food sensitization, particularly when considering a food challenge.

• Consider food-specific IgE and skin prick testing in children with FPIES as a positive test can infer a greater chance of persistent disease.

• Boyce et al. Journal Allergy Clin Immunology 2010 • Nowak-Wegrzyn et al. Journal Allergy Clin Immunology 2017

Case 2: Jennifer

• Breastfed infant just starting solid foods

• At 5 months of age, had first episode of repetitive, non-bloody, non-bilious vomiting followed by diarrhea and lethargy after 4th day of rice cereal mixed with cow’s milk formula

• Mother suspected GI illness and treated with rehydration fluids and Jennifer improved

44

Jennifer

• Two days later, rice cereal was offered again (mixed with cow’s milk formula) with a recurrence of symptoms 2 hours later

• This time they went to the emergency department and intravenous fluids were given and mom tells the doctor that she suspects the rice cereal

• They were referred to the allergy clinic

45

Jennifer – Diagnosis

History - Currently eating apple, banana - Quinoa, baby rice

- Reaction: Baby rice WITH standard

infant formula on 2 occasions

46

Perform any testing?

• Yes (required to diagnose FPIES)

• No – never

• Yes (to investigate co-morbid sensitization)

Perform a food challenge?

• Yes • No • Yes – to baked milk

When do you challenge for FPIES?

• OFC every 18-24 months in patients who have not had a recent reaction.

• Protracted vomiting and dehydration necessitate fluid resuscitation in approximately 50% of reactive challenges.

• Considered high-risk and should be conduction in a setting with IV access.

• May consider challenge to high-risk foods never ingested in the office

Structured Visits

• Burden awareness is key

• Assess QOL, history and trajectory- utilize ancillary staff

• Discuss previous recommendations: “What has and what has not worked?”

• Ask questions: “Are you having a difficult time feeding your child?”

• Lifestyle competency

• Evaluate short and long term goals

• Informed decision: Educate and provide options

• Division of responsibility

• Assess readiness and make appropriate referrals for practical management obstacles

Nutritional considerations

What I do?

• Provide guidance during the introduction of complementary foods – give a list of foods

• Monitor growth (weight and height/length)

• No need to avoid products with precautionary allergen labeling in patients with FPIES

• Textures and chewing: Recommend foods that prevent all levels of feeding dysfunction

diet 2. If formula feeding – carefully increase formula milk intake 3. Do the milk ladder 4. 1 and 2

Changes to the Milk Ladder

Eosinophilic Esophagitis I DON’T THINK WE NEED TO DO EOE – I AM DOING THE EOE TALK THE DAY BEFORE

Eve is a 28-month-old female with EoE • Medical history: EoE on diet therapy excluding milk (empiric) and

eggs, peanut, almond and barley (test directed). • Dietary history: Parents are concerned because Eve eats a very

small volume of food. • Supplements: Poly Vi Fluor (400 IU D), • L'il Critter gummies calcium and D (200 mg calcium and 200 IU

vitamin D) • L'il Critters Vitamin C (126 mg vitamin C and 200 IU D and 3 mg zinc)

with Echinacea.

71

Growth

• Growth history: Growth from birth has been following closely around the 25th percentile.

• She has recently had a weight loss of 1.4 pounds (from 23-24 months of age) and there has been no follow up weight check since this time. Weight now dropped to the 3rd percentile.

• Eve was not present so weight/height could not be documented. Mukkada 2010; Furuta 2018 72

Food intake Foods currently in diet: • Meat: Chicken, turkey, beef and pork • Vegetable: Carrot, cucumber, lettuce, olive, onion, squash, tomato

and white potato • Fruit: Apple, banana, cantaloupe, grape, lemon, mango, orange,

pear, pineapple, raspberry and watermelon • Grain: Wheat, rice, corn, oat (Apple Jacks Cereal) • Other: Soy, cod fish

73

Snacks

• Snack-food is provided on demand; parents report Eve is constantly asking for foods (as she is hungry)

• Few actual meals - mostly salty (pretzels, veggie sticks) and sweet snacks (crackers, sweetened dry cereal snacks, fruit snacks, fruit, fruit punch) and an occasional slice of bologna or chicken nugget or 1/4 hotdog

74

Should we add a commercial milk/beverage or formula?

1. No need; use commercial milks 2. Extensively hydrolyzed formula 3. Amino acid based formula


Growth and EoE – mainly elemental formulas

76

Study Growth outcome

Kelly et al. 1995 ‘…poor weight gain had resolved’

Al-Hussaini et al. 2013 Corrected growth after 2 months of therapy

Liacouras et al. 2005 ‘…no significant weight loss’, ‘or alteration of growth parameters (height, weight, head circumference)’ in those on dietary therapy, however reported that n=5 patients considered to have failure to thrive had a significant increase in weight after receiving AAF

Kagalwalla et al. 2005 Children with failure to thrive on AAF (n=14) mean weight gain was 1.03kg (range 0.1-2.1kg), and of children identified with failure to thrive on the EED (n=5), mean weight gain was 1.32kg (range 0.9-2kg), after six weeks of intervention

Colson et al. 2014 (n=59) diet height and weight gains were significant after 5 months, but weight-for-height z-scores did not change.
