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 ...
A drug allergy is an allergy to a drug, most commonly a medication, and is a form of adverse drug reaction. Medical attention should be sought immediately if an allergic reaction is suspected. An allergic reaction will not occur on the first exposure to a substance.
Type I hypersensitivity (or immediate hypersensitivity), in the Gell and Coombs classification of allergic reactions, is an allergic reaction provoked by re-exposure to a specific type of antigen referred to as an allergen. [1] Type I is distinct from type II, type III and type IV hypersensitivities. The relevance of the Gell and Coombs ...
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 ...
[2]: 118 The rash may also be one of the potentially lethal severe cutaneous adverse reactions, the DRESS syndrome, Stevens–Johnson syndrome, or toxic epidermal necrolysis. [3] [4] Systemic manifestations occur at the time of skin manifestations and include a high number of eosinophils in the blood, liver inflammation, and interstitial nephritis
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 ...
Patients with measles will have the rash but there are other syndromes and infections that will display the same symptom such as patients with Kawasaki disease, [4] meningococcal petechiae or Waterhouse-Friderichsen syndrome, [4] Dengue, Roseola, congenital syphilis, [5] rubella, [4] Echovirus 9, [4] drug hypersensitivity reactions (in ...
TEN is a type of severe cutaneous adverse reactions (SCARs), together with SJS, a SJS/TEN, and drug reaction with eosinophilia and systemic symptoms. [5] It is called SJS when less than 10% of the skin is involved and an intermediate form with 10 to 30% involvement. [3] Erythema multiforme (EM) is generally considered a separate condition. [6]
