Possible Causes for Urticaria

Insect Bite

Papular urticaria. [symptoma.com]

Insect bites and the associated hypersensitivity reactions known as papular urticaria account for a significant number of all referrals from pediatricians and dermatologists [ncbi.nlm.nih.gov]

Papular urticaria Papular urticaria is a hypersensitivity reaction, most often in a young child due to fleabites and/or mosquito bites. [dermnetnz.org]

Hypersensitivity

These skin reactions include perioral dermatitis, stomatitis, and urticaria. [fluoridealert.org]

The case reported here is one of simultaneous contact urticaria and a delayed-type contact allergy to thiocolchicoside. [ncbi.nlm.nih.gov]

The authors present 2 case reports of selective cefazolin hypersensitivity: a 49 year-old woman with a history of two perioperative reactions (urticaria and severe anaphylaxis [ncbi.nlm.nih.gov]

Food Allergy

The patient did not have a history of food allergy or urticaria. [ncbi.nlm.nih.gov]

For generalized urticaria and anaphylaxis, intramuscular epinephrine is the first and fundamental treatment line. [ncbi.nlm.nih.gov]

We describe the case of a 26-year-old man who developed pruritus, generalized urticaria, and severe angioedema of his lips and tongue with dyspnea within 15 minutes after [ncbi.nlm.nih.gov]

Contact Dermatitis

(one-time event of several hours’ duration); Chronic urticaria (longer than 6 weeks); Cholinergic urticaria (precipitated by sweating secondary to heat); Dermographism urticaria [dermatologyadvisor.com]

Contact urticaria can be immunological (due to allergy) or non-immunological. It is a form of inducible urticaria. Contact urticaria Who gets contact urticaria? [dermnetnz.org]

CUS can be described in two broad categories: nonimmunologic contact urticaria (NICU) and immunologic contact urticaria (ICU). [dermatologyadvisor.com]

Histamine Intolerance

The clinical evidence for histamine intolerance is based on chronic headache, diarrhoea, vomiting, flush, urticaria, asthma-like symptoms, rhinitis and others. [ncbi.nlm.nih.gov]

Like other forms of urticaria, PUPPP can be treated with topical steroid creams. [ic.steadyhealth.com]

One week after starting this medication, the pruritus had resolved and the erythema/urticaria had abated; the pigmentary alteration had improved, but still remained. [ncbi.nlm.nih.gov]

Drug Hypersensitivity

Patients were divided into 5 groups based on their accompanying diseases (chronic urticaria, asthma, rhinitis/rhinosinusitis). [ncbi.nlm.nih.gov]

Fifteen patients (75%) were classified as having single-NSAID-induced urticaria and/or angioedema, three patients were classified as having NSAID-induced urticaria and/or [ncbi.nlm.nih.gov]

= 1) and single NSAID-induced urticaria/angioedema and/or anaphylaxis (n = 11). [ncbi.nlm.nih.gov]

Drug Eruptions

Of note, urticaria may precede anaphylaxis and should therefore be taken very seriously. [symptoma.com]

Pruritus and urticaria can be controlled with oral antihistamines and topical corticosteroids. [merckmanuals.com]

NSAIDs were also the main offenders in causing urticaria, angioedema and morbilliform rash [Table 4] and [Table 5]. [ijdvl.com]

Urticaria

Chronic urticaria comprises both chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU) that includes physical and non-physical urticarias. [ncbi.nlm.nih.gov]

Anaphylaxis

Anaphylaxis is rarely associated to cold-induced urticarial (CU), a particular form of physical urticaria that is difficult to diagnose and manage. [ncbi.nlm.nih.gov]

Full-blown anaphylaxis includes urticaria and angioedema with hypotension and bronchospasm. How does anaphylaxis arise? [dermnetnz.org]
