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.

Summary

This study will observe 65 children, aged 1 to 24 months, hospitalized with bronchiolitis at Assiut University Hospital. Researchers will collect information on family, social, and medical factors to identify what makes the illness more severe. The goal is to help doctors predict disease course and improve care, but no experimental treatments are being tested.

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 study could help doctors predict which children are at higher risk for severe bronchiolitis, leading to earlier and better care.
What could go wrong
This is an observational study, not a treatment trial. It will not test any new drug or therapy, so it cannot directly improve outcomes. Results may not apply to all populations.

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 hospitalized children aged 1 to 24 months presenting with acute bronchiolitis at Assiut University Hospital. Patients are eligible if they have a clinical diagnosis confirmed by a pediatric pulmonologist according to the AAP 2014 criteria, presenting with a preceding upper respiratory infection, wheezing, tachypnea, and signs of respiratory distress. The population strictly excludes children with underlying comorbidities that might independently affect respiratory severity, including known congenital heart disease, chronic lung disease, immunodeficiencies, and neuromuscular disorders. Furthermore, patients with a history of recurrent wheezing, extreme prematurity (gestational age \<32 weeks without recovery) or low birth weight (\<1500g without catch-up growth), and those who have received systemic steroids or antibiotics within the past two weeks are excluded from the study cohort.

Inclusion Criteria: * Children aged 1-24 months presenting with acute bronchiolitis, defined per AAP 2014 criteria: preceding upper respiratory infection, wheezing, tachypnoea (\>60 breaths/min \<2 months, \>50 \<12 months, \>40 \>12 months), and signs of respiratory distress (nasal flaring, grunting, retractions). * Confirmed clinical diagnosis by a pediatric pulmonologist. Exclusion Criteria: * Known congenital heart disease, chronic lung disease (e.g., bronchopulmonary dysplasia), immunodeficiency, or neuromuscular disorders. * Recurrent wheezing suggesting asthma. * Gestational age \<32 weeks without recovery or birth weight \<1500g without catch-up growth. * Immunosuppression, recent (within 2 weeks) systemic steroids or antibiotics.
