These range from mild cases resolving upon cessation of the causative drug to severe cases involving complex disease progression and potential fatality. A hallmark of DIHS/DRESS is the sequential reactivation of herpesviruses, particularly human herpesvirus 6 (HHV-6), during the disease course, contributing to recurrent symptoms. Viral reactivation can lead to critical complications, including infectious DIHS/DRESS-associated complications (iDACs) and autoimmune sequelae (aDACs). Managing DIHS/DRESS remains challenging due to its complexity, requiring precise prediction and tailored treatment strategies. Recent studies suggest that early-stage classification using the DIHS/DRESS Severity (DDS) score may help identify refractory cases, including DACs. Furthermore, early intervention with anti-cytomegalovirus (anti-CMV) therapy can mitigate iDACs caused by CMV reactivation, preventing progression to severe CMV-related diseases. Long-term follow-up is crucial, as aDACs can manifest even 3 years postonset. Serial monitoring is recommended, particularly in patients treated with intravenous immunoglobulin or corticosteroid pulse therapy, which are recognized risk factors for aDAC development. This review highlights DIHS/DRESS management strategies, focusing on its clinical features, the role of viral reactivation, and therapeutic interventions.</p>","PeriodicalId":48861,"journal":{"name":"Allergology International","volume":" ","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144054930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, HLA testing holds substantial clinical potential as a genetic diagnostic tool to avoid drug eruptions. For instance, when prescribing drugs like carbamazepine and lamotrigine, which are known to cause severe drug eruptions, preemptive HLA genetic testing can help predict an individual's risk.

AGS is especially prevalent in regions with high tick exposure and has become a global public health concern, with rising cases across continents. Despite growing research, including recent findings suggesting that asymptomatic α-gal sensitization may contribute to coronary artery disease, the precise immune mechanisms-particularly B cell-mediated IgE production following tick bites-remain poorly understood.
