We believe breast milk is the best food for infants. When in consultation with their healthcare professional, mothers and families find that optimal breastfeeding is not possible due to their infant’s medical condition, formulas for special medical purposes play a vital role in providing essential nutrients to infants. We have a global commitment to market breast-milk substitutes responsibly.

CoMiSS® Awareness Tool
A SIMPLE, FAST AND EASY-TO-USE AWARENESS TOOL TO RECOGNIZE COW'S MILK-RELATED SYMPTOMS

A simple, fast and easy-to-use awareness tool to recognize cow’s milk-related
symptoms in infants and young children
WHAT IS CoMiSS®?
The CoMiSS® awareness tool has been developed in consensus with 11 clinicians whose expertise is in managing children with gastrointestinal problems and / or atopic diseases.

The CoMiSS®, published in 2015 in Acta Paediatrica1, increases the awareness of the most common symptoms of CMPA that in turn can aid an earlier accurate diagnosis. It also helps to minimize over- and under- diagnosis of cow's milk-related symptoms as well as evaluate and quantify the evolution of symptoms during a therapeutic intervention. It is important to note that CoMiSS® is NOT a diagnostic test for cow's milk protein allergy (CMPA), and it does not replace a food challenge; its usefullness will need to be evaluated in a prospective randomized study.

The CoMiSS® is intended for primary healthcare providers who are all too often very limited in time and thus need a tool that is simple, fast and easy-to-use.
THE CoMiSS® AWARENESS TOOL
Most patients with obvious CMPA, such as those with anaphylactic reactions or immediate IgE mediated reactions will not be picked-up by the CoMiSS® awareness tool. However, the majority of infants present with non-IgE mediated reactions to cow’s milk protein. These infants are difficult to identify as they present with delayed reactions, often moderate to mild in severity and often in different organ systems.

Functional gastrointestinal symptoms such as regurgitation and vomiting, constipation, crying and colic are considered non-IgE mediated reactions. Atopic eczema is often not recognized as a possible consequence of ingestion of cow's milk protein.

If you suspect your patient is suffering from symptoms that may be suggestive of CMPA, use the CoMiSS® tool to score and assess the likelihood of CMPA.

HOW TO USE CoMiSS® IN CLINICAL PRACTICE

CoMiSS® quantifies the number and severity of symptoms.

Suspicion of 'cow’s milk-related symptoms' based on the presence of a combination of the following symptoms:

Digestive symptoms of cow’s milk protein allergy

Digestive


Frequent regurgitation, vomiting, diarrhea, constipation (with/without perianal rash), blood in stool.

Respiratory symptoms of cow’s milk protein allergy

Respiratory


Runny nose, (otitis media), chronic cough, wheezing (unrelated to infection).

Skin-related symptoms of cow’s milk protein allergy

Skin


Atopic dermatitis, angioedema, urticaria unrelated to acute infections, drug intake manifestations. ​​​​​​​​​​​​​​

General symptoms of cow’s milk protein allergy

General


Persistent distress or colic (≥ 3 hours per day wailing/irritable) at least 3 days/week over a period of > 3 weeks.

BACKGROUND: SYMPTOMS RELATED TO INTAKE OF COW'S MILK
Many infants present with symptoms that can be related to intake of cow’s milk. Cow’s milk protein allergy (CMPA) however is often not considered as a diagnosis, mainly due to the lack of specific diagnostic marker.

There are two groups of patients:
- those with obvious CMPA
- those with unclear symptoms in different organ systems

The first group is easy to recognize:
- consists mainly of infants with immediate/ rapid reactions
- most of the time IgE mediated

However, this group represents a minority of all the infants with suspected cow’s milk-related symptoms seen by primary healthcare providers.

In many cases, parents report some or all of these symptoms:
- Infant crying, having 'colic'
- Difficult defecation or 2-3 loose stools per day
- Regurgitates 4 to 6 times a day
- Mild patches of atopic dermatitis

Due to the lack of diagnostic test for CMPA (other than the challenge test), an awareness tool to recognize cow’s milk-related symptoms for use by healthcare providers may increase the awareness and the recognition of symptoms possibly related to cow’s milk, leading to an accurate diagnosis at an earlier stage.

Digestive


Prevalence of digestive symptoms

Up to 60% of affected infants have digestive symptoms.

Respiratory


Prevalence of respiratory symptoms

Up to 30% of affected infants have respiratory symptoms.

Skin

Prevalence of skin-related symptoms

Up to 70% of affected infants have skin-related symptoms.

General




Inconsolable crying is very common in infants with CMPA, while anaphylaxis is very rare.

IMPORTANT NOTICE: Mothers should be encouraged to continue breastfeeding even when their babies have cow’s milk protein allergy. This usually requires qualified dietary counseling to completely exclude all sources of cow’s milk protein from the mothers’ diet. If a decision to use a special formula intended for infants is taken, it is important to follow the instructions on the label. Unboiled water, unboiled bottles or incorrect dilution can make babies ill. Incorrect storage, handling, preparation and feeding can eventually lead to adverse effects on the health of babies. Formula for special medical purposes intended for infants must be used under medical supervision.
