Study flags markers for persistent child sinusitis
EMJ Reviews··25 Jul
A five year prospective study of one hundred thirty three preschool children identified markers predicting persistent chronic rhinosinusitis and later house dust mite allergic rhinitis. CRS persisted in thirty five percent who completed follow up. Infant food allergy raised later HDM allergy risk. SN five scores above three point six tripled CRS odds by school age.

What It Means For You
- Parents of preschoolers with severe sinus symptoms may face higher long term ENT and allergy care needs.
- Early SN five scoring could help clinicians identify children who might benefit from timely allergen immunotherapy.
- ILC two cells detected more often in nasal samples from children whose CRS persisted through the study period.
What's Happening
- Researchers followed children aged four to eight with CRS symptoms for five years in a prospective trial.
- One hundred seventeen participants completed follow up, with thirty five percent showing persistent CRS.
- Food allergy history raised odds of later HDM induced allergic rhinitis nearly four fold in the cohort.
Preschool Symptoms Predict School Age CRS
- The study published in Pediatric Allergy Immunology 2026 examined clinical and immunological progression markers.
- Combining baseline symptom burden with allergy history improved prediction of HDM sensitivity before school age.
- Authors suggest earlier identification could support timely immunotherapy though the model needs further validation.
