[Widal's triad : clinical manifestations, pathophysiology and therapeutic advances].

NSAID-Exacerbated respiratory disease (also known as Samter's or Widal's triad, aspirin-exacerbated respiratory disease) is characte- rized by asthma, nasal polyposis and hypersensitivity to NSAIDs. The pathogenesis of this chronic inflammation arises from an imbalance in arachidonic acid metabolism, leading to an increase in pro- inflammatory cysteinyl-leukotrienes. The treatment is based on drug management of asthma and polyps and, in advanced situations, surgical management of polyposis. Monoclonal antibodies have shown promising results in the further medical treatment of this entity.
