AbstractBackgroundPlatelet activating factor (PAF) is an endogenous, active phospholipid released from inflammatory cells, platelets, and endothelial cells, and is involved in the regulation of immune responses. Degradation of PAF by PAF acetylhydrolase (PAF-AH) has been shown to be associated with anaphylaxis, asthma, and peanut allergy. The purpose of this study was to investigate relationships among clinical parameters, including urticaria severity and treatment responsiveness, and PAF and PAF-AH levels in sera from patients with chronic spontaneous urticaria (CSU).MethodsSerum PAF and PAF-AH levels were measured by enz...

Discussion Atopic dermatitis (AD) has a prevalence of 3-5% in the overall U.S. population but is increasing with an estimated 10-15% lifetime risk in childhood. It is even more common in children of color with a prevalence in African-American/black children of 17% and Hispanic children of 14%. Health care utilization data also appears to support more severe disease in children of color also. Atopic dermatitis or eczema is a common dermatological skin problem which characteristically is a pruritic, papular eruption with erythema. Like most papulosquamous eruptions it often occurs in intertrigenous areas in people with alle...

Purpose of review Nonsteroidal anti-inflammatory drug (NSAID) is one of the most frequently prescribed medications in the medical field, and hypersensitivity to NSAID is a common adverse drug reaction encountered. However, NSAID hypersensitivity presents a variety of symptoms caused by diverse pharmacological and immunological mechanisms. Recent findings Owing to the heterogeneity of the disease, a new concept for the classification of NSAID hypersensitivity has recently been proposed to diagnose and manage NSAID hypersensitivity for personalized treatment. Acute and delayed reactions were distinguished in this classi...

Abstract Modern lifestyle with the increasing use of air conditioner (AC) has been linked with breathing difficulties, irritation, dryness, and other symptoms. Hence, dust mites were isolated from AC filters, which causes allergic diseases. A total of 95 dust samples were collected from AC filters from hospitals, guest house, office, school, and homes in Chandigarh, India. The highest concentration of dust mites was detected from hospitals (9/g), offices (7/g), households (6/g), guest houses (3/g), and schools (0/g). Based on the morphology of dust mites observed under a light microscope, Dermatophagoides and Acar...

Authors: Han JH, Je YJ, Yoon HJ, Ahn JG, Lee JS, Park JW, Park HJ Abstract Cryopyrin-associated periodic syndrome (CAPS) is a hereditary autoinflammatory syndrome caused by mutations in NLRP3 (encoding cryopyrin), which presents with fever, fatigue and arthralgia. Thus far, however there have been no reports of CAPS in Korea. Herein, we report 3 cases of CAPS for the first time in Korea. The first case, a 28-year-old man with recurrent urticaria, arthralgia and fever induced by cold, all of which were observed in his father, showed elevated erythrocyte sedimentation rate and C-reactive protein. He exhibited a p.Gly...

CONCLUSIONS: The rate of anaphylaxis in patients with ColdU in a tropical country was lower than those reported by other studies conducted intemperate climates. On the other hand, the number of female patients, mean age at symptom onset, atopy rate, rate of concomitant chronic spontaneous urticaria and mean CTT were higher. PMID: 31172722 [PubMed]

Allergy to galactose-alpha-1,3-galactose (alpha-gal) presents as an IgE-mediated, yet delayed-onset hypersensitivity reaction to non-primate mammalian meat.1 Alpha-gal sensitization develops after tick bite exposure.1-3 The lone-star tick (Amblyomma americanum) represents the North American vector, spanning a relatively vast southeast, mid-west, and northeast geographic distribution.4 Allergic manifestations include urticaria/angioedema, abdominal pain/diarrhea, or anaphylaxis, occurring approximately 3-6 hours after ingestion.

Recently, new diagnostic tools and therapeutic agents have significantly increased the survival rate of cancer patients compared to that in the past. As the number of cancer survivors exposed to multiple courses of chemotherapy increases, more patients become sensitized to chemotherapeutic agents and suffer from hypersensitivity reactions (HSRs).1-3 HSRs to chemotherapeutic agents range from mild cutaneous urticaria to severe reactions, such as life-threatening anaphylaxis, and even death.4 Most HSRs are unpredictable, such that they threaten the safety of patients; moreover, they can be uncontrollable, and severe HSRs lim...

AbstractThis review article aims to outline what is known in the pathophysiology of chronic rhinosinusitis with nasal polyposis (CRSwNP) and describe the mechanism of the biologic agents being investigated for this disease. Chronic rhinosinusitis with nasal polyposis is an inflammatory disease of the nasal and paranasal mucosa, which causes symptoms of nasal obstruction, hyposmia, and rhinorrhea. Conventional therapy for CRSwNP includes intranasal corticosteroids (INCS) and polypectomy, but INCS offer only modest benefits, and recurrence after surgery is common. Therefore, effective pharmacologic therapies for CRSwNP are b...
