Patients with psoriatic arthritis have higher levels of FeNO than those with only psoriasis, which may reflect a higher prevalence of a subclinical respiratory involvement

ConclusionsPsA patients seem to have more commonly subclinical airway inflammation than those with only psoriasis. Further studies are needed to replicate these findings.Key Points•Fraction of exhaled nitric oxide (FeNO) is a useful device to detect and monitor airway inflammation not only in asthma but also in systemic inflammatory diseases such as psoriatic arthritis and psoriasis.• Clinicians should be aware to check respiratory diseases in patients with psoriatic arthritis.
