TL;DR: This guideline covers the definition and classification of urticaria, taking into account the recent progress in identifying its causes, eliciting factors and pathomechanisms, and outlines evidence-based diagnostic and therapeutic approaches for the different subtypes ofUrticaria.

TL;DR: Patients with chronic spontaneous urticaria are more likely to be associated with HLADR4, to have autoimmune thyroid disease, a more prolonged disease course and may be less responsive to H1‐antihistamine treatment than those with a negative ASST (ASST−) although more evidence is needed to confirm these observations conclusively.

TL;DR: It was proposed that a study should be undertaken to prospectively validate potentially relevant clinical criteria (from the history, examination and routinely available clinical investigations) against a new ‘gold standard’ for the diagnosis of ACU (positive autoreactivity, functional bioassay and immunoassay) to define preliminary criteria sets for the diagnosed ACU based on clinical and laboratory features with highest individual sensitivity and specificity.
