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 ...
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 ...
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 ...
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 ...
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 ...
Eosinophilic cellulitis (Wells' syndrome) Eosinophilic fasciitis (Shulman's syndrome) Eosinophilic granuloma; Eosinophilic granulomatosis with polyangiitis; Eosinophilic pustular folliculitis of infancy (eosinophilic pustular folliculitis in infancy, infantile eosinophilic pustular folliculitis, neonatal eosinophilic pustular folliculitis)
Eosinophilic cellulitis, also known as Wells' syndrome (not to be confused with Weil's disease), is a skin disease that presents with painful, red, raised, and warm patches of skin. [2] The rash comes on suddenly, lasts for a few weeks, and often repeatedly comes back. [2] Scar formation does not typically occur. [1]
