WebThe cornerstone of hypersensitivity pneumonitis (HP) management is having patients avoid the inciting antigen (IA). Often, despite an exhaustive search, an IA cannot be found. The objective of this study was to examine whether identifying the IA impacts survival in patients with chronic HP. WebHypersensitivity pneumonitis (HP) is one of the most common interstitial lung diseases (ILD), that presents unique challenges for a confident diagnosis and limited therapeutic options. The disease is triggered by exposure to a wide variety of inciting antigens in susceptible individuals which results in T-cell hyperactivation and bronchioloalveolar …

WebHP is the culmination of a dysregulated immune response to an inciting inhaled antigen when identified in a sensitized susceptible individual manifesting as inflammation and/or fibrosis of the lung parenchyma and small airways ().Previously described categories of acute, subacute, and chronic HP are arbitrary and fail to meaningfully inform expectations … WebMar 3, 2024 · Aetiology and pathogenesis. HP occurs when susceptible individuals develop an exaggerated immune response following inhalation of an inciting antigen or mixture of antigens [3, 4].Several genetic polymorphisms, including those in major histocompatibility complex class II, have been associated with susceptibility to HP [5–8].The MUC5B allele … WebSeveral potential inciting agents have been identified or proposed. In the case of childhood ITP, many patients give a history of a recent infection. It has been hypothesized that ITP results from molecular mimicry engrafted on a normal immune repertoire, such that the immune thrombocytopenia resolves once the inciting antigen has been eliminated. de wall couch
