Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to evaluate the growth parameters and nutritional status of infants who are receiving amino acid-based formula due to cow's milk protein allergy or other medical indications.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This prospective observational study will assess infants who are exclusively fed amino acid-based formula. Participants will be followed over a period of 6 months, and anthropometric measurements (weight, length, head circumference) will be recorded monthly. Growth velocity and nutritional status will be analyzed and compared with WHO growth standards.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Infants aged 1 to 12 months at the time of enrollment.
2. Infants who are exclusevel or predominantly fed amino acid-based formula (AAF) in addition to elimination diet for at least 12 consecutive weeks.
3. Infants who are diagnosed as CMPA by CoMiSS score ≥ 10 and confirmed by OFC test.
4. Infants with informed parental or guardian consent to participate in the study.

Exclusion Criteria

* 1- Infants with congenital anomalies or syndromes affecting growth and development (e.g., trisomy 21, major cardiac defects).

2- Infants with chronic systemic illnesses unrelated to feeding (e.g., cystic fibrosis, chronic kidney disease).

3- Infants receiving additional specialized nutrition support (e.g., parenteral nutrition or tube feeding not involving AAF).

4- Infants with incomplete or insufficient medical records at the time of assessment.5- Infants who have been on AAF for less than 4 weeks or whose feeding regimen is not stable.

6- Infants whose parents or legal guardians decline or withdraw informed consent.
