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 ...
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 ...
The DRESS syndrome is a Type IV, Subtype IVb, hypersensitivity drug reaction, i.e. a reaction dependent on CD4(+) cells and the cell- and tissue-injuring action of eosinophils. [ 2 ] [ 8 ] Skin lesions inflict 73% to 100% of afflicted individuals; they are generally infiltrative macules and plaques .
The SCARs group of disorders includes four other drug-induced skin reactions: drug reaction with eosinophilia and systemic symptoms (DRESS syndrome), Stevens–Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and Stevens–Johnson/toxic epidermal necrolysis overlap syndrome (SJS/TEN). SJS, SJS/TEN, and TEN, while initially described as ...
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).
This contrasts with the other types of SCARs disorders, i.e., the DRESS syndrome which is a Type IV, Subtype IVb, hypersensitivity drug reaction dependent in part on the tissue-injuring actions of eosinophils [31] [32] and acute generalized exanthematous pustulosis which is a Type IV, subtype IVd, hypersensitivity reaction dependent in part on ...
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 ...
The reaction generally includes a constellation of fever; urticarial polycyclic wheals (a rash that can look similar to hives with small swellings that overlap each other [2]) with central clearing on the trunk, extremities, face, and lateral borders of the hands and feet; oral edema without mucosal involvement; lymphadenopathy; arthralgias; myalgias; and mild proteinuria.
