The symptoms of DRESS syndrome usually begin 2 to 6 weeks but uncommonly up to 8–16 weeks after exposure to an offending drug. Symptoms generally include fever, an often itchy rash which may be morbilliform or consist mainly of macules or plaques, facial edema (i.e. swelling, which is a hallmark of the disease), enlarged and sometimes painful lymph nodes, and other symptoms due to ...
The syndrome is also associated with other maladies caused by high levels of blood eosinophils such as the various hypereosinophilia-related disorders: persistent asthma and allergic rhinitis and, more significantly, eosinophil-based and lymphocyte-based inflammation of the liver (>70% of cases), kidney (20% to 40% of cases), lung (~33% of ...
Studies on the DRESS syndrome, Stevens–Johnson syndrome (SJS), toxic epidermal necrolysis (TEN) and SJS/TEN overlap indicate that many individuals are predisposed to develop these reactions to a particular medication based on their genetically determined expression of particular human leukocyte antigen (i.e. HLA) alleles or T-cell receptors ...
Eosinophilia is a condition in which the eosinophil count in the peripheral blood exceeds 5 × 10 8 /L (500/μL). [1] Hypereosinophilia is an elevation in an individual's circulating blood eosinophil count above 1.5 × 10 9 /L (i.e. 1,500/μL).
Depending on eosinophil target-organ infiltration, the clinical presentation of hypereosinophilic syndrome (HES) varies from patient to patient. [13] Individuals with myeloproliferative variant HES may be more likely to experience mucosal ulcerations involving the genitalia or airways, while patients with lymphocytic variant HES typically exhibit prominent skin symptoms such as urticarial ...
Allopurinol hypersensitivity syndrome (AHS) typically occurs in persons with preexisting kidney failure. [3]: 119 Weeks to months after allopurinol is begun, the patient develops a morbilliform eruption [3]: 119 or, less commonly, develops one of the far more serious and potentially lethal severe cutaneous adverse reactions viz., the DRESS syndrome, Stevens Johnson syndrome, or toxic epidermal ...
Drug reaction with eosinophilia and systemic symptoms (DRESS) is a specific type of DIHS that may be linked to HHV-7 as the condition may develop in response to herpesvirus antigens. In one study, 76% of the 40 examined patients with DRESS exhibited some reactivation of Epstein-Barr virus, HHV-6, or HHV-7.
Eosinophilic granulomatosis with polyangiitis consists of three stages, but not all patients develop all three stages or progress from one stage to the next in the same order; [7] whereas some patients may develop severe or life-threatening complications such as gastrointestinal involvement and heart disease, some patients are only mildly affected, e.g. with skin lesions and nasal polyps.
