Among the HLA class II alleles, DRB1*04 was observed significantly more often in the study population (p < 0.001), mainly in the autoimmunological subtype of urticaria.
In haplotype analysis, the HLA-DRB1(*)1302-DQB1(*)0609-DPB1(*)0201 was significantly higher in the aspirin-induced urticaria (8.0%) than in the aspirin-intolerant asthma (0.7%, P=0.0014) and normal controls (2.0%, P=0.0006).
The aim of this study was to compare the clinical features, total eosinophil count, serum levels of interleukin (IL)-18, IL-18 binding protein (BP), IL-1 receptor-like (RL) 1, and IL-33 and compare with tryptase to examine if any differences could be found between patients who experienced anaphylaxis and urticaria.
IL-1 receptor antagonist anakinra is usually highly efficient in Schnitzler syndrome (SS), a rare inflammatory condition associating urticaria, fever, and IgM monoclonal gammopathy.
As frequent attacks of urticaria and associated arthralgia had a debilitating effect on the child's lifestyle, a trial of IL-1-receptor antagonist (anakinra) was instituted.

Familial Mediterranean fever (FMF), mevalonate-kinase deficiency (MKD) and tumour necrosis factor (TNF) receptor-associated periodic syndrome (TRAPS) are the three monogenic disorders subsumed under the term periodic fevers, while a systemic inflammation dominated by a characteristic urticarial rash associated with a number of other clinical manifestations is typical of familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS) and chronic infantile neurological cutaneous and articular syndrome (CINCA).
The genotype frequencies of TNF-1031T>C and TNF-863C>A were significantly higher in the AIU patients than in the normal controls in both co-dominant (P = 0.014, P = 0.007) and dominant (P = 0.007, P = 0.004) models.
