ConclusionsThe wide number of anti-IL-5 antagonists or IL-5 receptor blockers let to possess alternative treatment selections for patients with serious hypereosinophilic sufferers. All the three drugs herein reviewed displayed a superb safety profile, plus a favorable clinical efficacy in the chosen sufferers. It remains true that we don’t still have reputable predictive markers to detect which single patient will respond individually to each and every of such expensive remedies. Also, the distinct routes of administrations would offer clinicians together with the opportunity to select the drug in line with drug characteristic and patient’s requires. At present, the very best biomarker in patient eligible for anti-IL-5 or IL-5ra is blood eosinophils, exhaled nitric oxide, and clinical phenotyping (age of onset of asthma, atopy, and presence of nasal polyposis). Predictive biomarkers permitting a far better prescription of a persona.
