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).
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.
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.
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.
IL-1 receptor antagonist anakinra is usually highly efficient in Schnitzler syndrome (SS), a rare inflammatory condition associating urticaria, fever, and IgM monoclonal gammopathy.
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.
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.
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).
Urticarial rash, one of the clinical manifestations characteristic of cryopyrin-associated periodic syndrome (CAPS), is caused by a mutation in the gene encoding for NLRP3 (nucleotide-binding oligomerization domain, leucine-rich repeats containing family, pyrin domain containing 3).
Dominant mutations in the CIAS1 gene cause a spectrum of autoinflammatory diseases such as familial cold autoinflammatory syndrome, FCAS, which is characterized by episodes of urticaria, arthralgia, fever and conjunctivitis after generalized exposure to cold.
The cryopyrin-associated periodic fever syndrome (CAPS) is an autosomal dominant autoinflammatory disorder caused by mutations in the NLRP3 gene and is typified by recurrent episodes of systemic inflammation resulting in fever, urticarial rash and arthralgia.
Analysis of serum APP concentrations revealed statistically higher serum concentrations of CRP, AGP and ACT in the entire group of patients with urticaria in comparison with the control group.
Diagnosis of C1-INH-HAE was based on family and/or personal history of recurrent angioedema without urticaria and on antigenic and/or functional C1-INH deficiency.
The following inclusion criteria was used: lack of response to antihistamines, steroids, and epinephrine; normal C4, C1 inhibitor (C1 INH) level and function; lack of urticaria or pruritus; occurrence without offending drugs; and positive family history.
Serum concentrations of C-reactive protein (CRP) and interleukin 6 (IL-6), key markers of acute phase response and of D-dimer, a marker of fibrin turnover were investigated in 58 CSU patients assessed with the urticaria activity score (UAS) and the controls.
Hereditary angioedema (HAE) is a rare genetic disease caused by a deficiency in functional C1-esterase inhibitor characterized by recurrent episodes of angioedema in the absence of associated urticaria.
