This study looked at whether people with ME/CFS have more nasal and sinus problems than the general population. Researchers compared 51 ME/CFS patients with healthy controls and people with allergies, using questionnaires and allergy skin tests. They found that most ME/CFS patients reported significant nasal and sinus symptoms, but about half of these cases appeared to be non-allergic in nature.
This study highlights that nasal and sinus symptoms are common in ME/CFS but may have different underlying causes than typical allergies. Understanding whether these symptoms are allergic or nonallergic could help develop better treatments and provides clues about what mechanisms drive ME/CFS symptoms.
This study does not prove that rhinitis causes ME/CFS or vice versa—it only shows they frequently occur together. The cross-sectional design cannot establish temporal relationships or causality. The findings may not generalize to all ME/CFS populations, as this was a single-center study with a relatively modest sample size.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
