Drug-induced sarcoidosis-like reactions (DISR).

Drug-induced sarcoidosis-like reactions (DISR). Chest. 2018 Apr 23;: Authors: Chopra A, Nautiyal A, Kalkanis A, Judson MA Abstract A drug-induced sarcoidosis-like reaction (DISR) is a systemic granulomatous reaction that is indistinguishable from sarcoidosis and occurs in temporal relationship with initiation of an offending drug. DISRs typically improve or resolve after the withdrawal of offending drug. Four common categories of drugs that have been associated with the development of a DISR are immune checkpoint inhibitors (ICIs), highly active anti-retroviral therapy (HAART), interferons (IFNs) and tumor necrosis factor alpha antagonists (TNF-alpha antagonists). Similar to sarcoidosis, DISRs do not necessarily require treatment, as they may cause no significant symptoms, quality of life impairment or organ dysfunction. When treatment of a DISR is required, standard anti-sarcoidosis regimens seem to be effective. As a DISR tends to improve or resolve when the offending drug is discontinued, this is another effective treatment for a DISR. However, the offending drug need not be discontinued if it is useful, and anti-granulomatous therapy can be added. In some situations, the development of a DISR may suggest a beneficial effect of the inducing drug. Understanding the mechanisms leading to DISRs may yield important insights into the immunopathogenesis of sarcoidosis. PMID: 29698718 [PubMed - as supplied by publisher]
