Background: Pro- and anti-inflammatory metabolites of arachidonic acid - eicosanoids - participate in skin homeostasis, affecting the growth and differentiation of keratinocytes. Alterations of 12-lipoxygenase (LOX) and 15-LOX and their metabolites have been described in the epidermis of patients with psoriasis, but systemic production of 12-LOX and 15-LOX eicosanoids has not been studied in the disease.
Objectives: To ascertain the frequencies of the genetic variants ALOX12 rs1126667 and ALOX15 rs11568070 in cases and controls, and to compare urinary metabolites of 12(S)-hydroxyeicosatetraenoic acid (HETE) between patients with psoriasis and healthy controls.
Background: Little is known about the course of aspirin-induced urticaria. A special regulatory role of cysteinyl leukotrienes and prostaglandin D(2) (PGD(2)) has been postulated.
Objective: We performed a long-term observation on clinical course, aspirin sensitivity, and urinary eicosanoids in patients with aspirin-induced urticaria.
Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most common causes of adverse drug reactions. Majority of them are of the hypersensitivity type. The two frequent clinical presentations of aspirin hypersensitivity are: aspirin-induced bronchial asthma/rhinosinusitis (AIA/R) and aspirin-induced urticaria/angioedema (AIU).

Aims Of The Study: Mutational screening in the region of the FcepsilonRIalpha gene promoter and the first exon with subsequent genetic variability assessment in allergic patients and a random population sample.
Methods: Allergic subjects were individuals with asthma or urticaria.
Background: We have reported that in patients with chronic idiopathic urticaria (CIU) who reacted adversely to aspirin, the frequency of the (-444)C allele of the leukotriene C(4) synthase gene (LTC4S) was higher than in patients who tolerated aspirin well.
Objectives: To study the pattern of aspirin-induced urticaria (AIU) in two families, with special interest on the polymorphisms of LTC4S (AA, AC, CC) and the glutathione S-transferase M1 and P1 genes (GSTM1 and GSTP1).
Methods: Of 74 patients with CIU and a history of aspirin hypersensitivity studied by us, two patients (probands) gave a family history of aspirin intolerance.
