What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study follows 120 children and adolescents in Spain who have been newly diagnosed with IgE-mediated fish allergy. Researchers will collect data on symptoms, test results, and molecular sensitization patterns to better understand how fish allergy presents in this population. The goal is to improve diagnosis, risk assessment, and personalized care for affected children.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could lead to more accurate diagnosis and personalized management for children with fish allergy.
What could go wrong
This is an observational study, so it does not test a treatment. Findings may vary by region and may not apply to all populations.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population consists of children and adolescents evaluated for suspected fish allergy in the Allergy Units of participating hospitals across Spain. Participants will be recruited consecutively from routine clinical practice at tertiary referral centers that are members of the Spanish Society of Allergy and Clinical Immunology (SEAIC). The study includes patients from multiple geographical regions, providing a representative sample of the Spanish pediatric population referred for specialized allergy assessment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Children and adolescents aged 0 to 17 years (up to 18 years of age). * First clinical episode compatible with IgE-mediated fish allergy. * Evidence of allergic sensitization demonstrated by at least one of the following: * Positive skin prick test (wheal diameter ≥3 mm compared with the negative control); or * Serum specific IgE ≥0.35 kUA/L to at least one fish species or fish allergen component. * Written informed consent obtained from the parent(s) or legal guardian(s), and assent from participants aged 12 years or older, when applicable. Exclusion Criteria: * Age ≥18 years. * Non-IgE-mediated fish allergy (e.g., fish-induced FPIES). * Severe dermographism, chronic urticaria, or severe atopic dermatitis preventing reliable interpretation of skin prick testing. * Inability to complete the diagnostic procedures required by the study. * Absence of informed consent or, when applicable, participant assent.
