A set of initial clinical criteria have been drawn up which it is recommended should be fulfilled before a patient is tested: at least three recurrent bouts, age at disease onset < 20 years and elevated levels of C-reactive protein, especially in individuals with urticaria and moderate fever.
Angiotensin-converting enzyme (ACE) inhibitor associated angioedema was detected in 39 subjects (17%) of 231 consecutive patients examined in the last 5 years at our out-patient clinic for symptoms of angioedema without urticaria.
It can present with urticaria or anaphylaxis and is usually associated with angiotensin-converting enzyme inhibitors (ACEis), complement deficiencies, or the side effects of tissue plasminogen activator (tPA).
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.
HIV+ controls (n = 12) had no detectable HIV-1 DNA, RNA, or p24 in the CNS; latent HIV+ cases (n = 10) showed high levels of HIV-1 DNA but no HIV RNA or p24; and HIVE cases (n = 10) had high levels of HIV-1 DNA, RNA, and p24.
IL-1beta- or TNF-alpha-positive cells were almost restricted to CD68-positive macrophages/microglia and mild expression of these cytokines by astrocytes was observed in two cases with severe HIVE.
Single- and double-labeled studies using antibodies against CD14, CD16, CD68, proliferating cell nuclear antigen (PCNA), Ki-67, von Willebrand factor, and HIV-1 p24 were performed using brain tissue from patients with HIVE, HIV-1 infection without encephalitis, and seronegative controls.
HIV+ controls (n = 12) had no detectable HIV-1 DNA, RNA, or p24 in the CNS; latent HIV+ cases (n = 10) showed high levels of HIV-1 DNA but no HIV RNA or p24; and HIVE cases (n = 10) had high levels of HIV-1 DNA, RNA, and p24.
In opiate addicts, there was generally higher baseline expression of CD68 and HLA-D in HIV negatives, and lower expression in HIV and HIVE, compared to individuals without opiate abuse.
Granzyme B and H precursor gene expression was up-regulated and interleukin (IL)-12A precursor, a maturation factor for natural killer cells and CTLs, was down-regulated in HIVE versus HIVnE brain.
Interleukin-6 is a gp130 utilizing cytokine that is consistently associated with allergic diseases like asthma and urticaria in humans where mast cells are known to play a critical role.
In HIV+ subjects without HIVE, shorter HO-1 (GT)n alleles associated significantly with lower expression of brain type I interferon response markers (MX1, ISG15, and IRF1) and T-lymphocyte activation markers (CD38 and GZMB).
HIV+ controls (n = 12) had no detectable HIV-1 DNA, RNA, or p24 in the CNS; latent HIV+ cases (n = 10) showed high levels of HIV-1 DNA but no HIV RNA or p24; and HIVE cases (n = 10) had high levels of HIV-1 DNA, RNA, and p24.
Single- and double-labeled studies using antibodies against CD14, CD16, CD68, proliferating cell nuclear antigen (PCNA), Ki-67, von Willebrand factor, and HIV-1 p24 were performed using brain tissue from patients with HIVE, HIV-1 infection without encephalitis, and seronegative controls.

Given the important role of basophils in the pathogenesis of urticaria and that CD63 serves as a useful marker for basophil activation and detecting, CD63 expression of basophils is a reliable tool for diagnosing allergy and hypersensitivity reactions to different allergens; the objective of this study was to investigate whether the level of basophil CD63 expression is correlated with allergen sensitization, serum autoreactivity and basophil reactivity in patients with CSU.
A PK/PD relationship curve suggests that dermal concentrations above 6.8 μM should lead to approximately 90% inhibition of histamine release from skin mast cells following activation of the Fc fragment of IgE receptor 1a, implicating a potential use for the compound in skin mast cell diseases such as urticaria.
SOD activity and expression were increased in all types of non-immediate reactions (urticaria, maculopapular exanthema and toxic epidermal necrolysis).
Single- and double-labeled studies using antibodies against CD14, CD16, CD68, proliferating cell nuclear antigen (PCNA), Ki-67, von Willebrand factor, and HIV-1 p24 were performed using brain tissue from patients with HIVE, HIV-1 infection without encephalitis, and seronegative controls.
