alcohol urticaria

Non-specific lipid transfer proteins (nsLTPs) are a family of plant pan-allergens that represent the primary cause of food allergies in the Mediterranean area, characterized by a wide range of clinical manifestations, ranging from the total absence of symptoms up to anaphylaxis. This wide variety of symptoms is related to the intrinsic capacity of nsLTPs to cause an allergic reaction in a specific subject, but also to the presence of co-factors exacerbating (i.e., exercise, NSAIDs, PPIs, alcohol, cannabis, prolonged fasting, menstruation, acute infections, sleep deprivation, chronic urticaria) or protecting from (i...

Wheat-dependent exercise-induced anaphylaxis (WDEIA) is an IgE-mediated food allergy with allergic symptoms ranging from intermittent urticaria to severe anaphylaxis that occurs when wheat ingestion is combined with augmenting cofactors such as exercise, non-steroidal anti-inflammatory drugs, or alcohol. In most cases, patients are identified by sensitization to ω5-gliadins in the gluten fraction of wheat. ω5-gliadin-negative subtypes of WDEIA are often difficult to diagnose and may be caused by Tri a 14 (wheat lipid transfer protein), after percutaneous sensitization with hydrolyzed wheat proteins, or, in rare cases, by cross-reactivity to grass pollen...

The majority of registry studies on atopic dermatitis include only patients and diagnoses from specialized healthcare. The aim of this retrospective, real-world cohort study was to evaluate the effect of atopic dermatitis severity on comorbidities and total morbidity, with comprehensive data from both primary and specialty healthcare registries covering the entire Finnish adult population. In total, 124,038 patients were identified (median age 46 years; 68% female) and stratified by disease severity. All regression analyses (median follow-up 7...

Aim of this study is to clarify the impact of cofactors on allergic reactions in patients sensitized to LTP and ω-5-gliadin. We retrospectively examined the charts of our outpatients from January 2015 to July 2019 and identified 157 patients seen for urticaria/angioedema or anaphylaxis after a meal, in presence or absence of cofactors and sensitized to LTPs (Pru p 3 and/or Tri a 14) and/or ω-5-gliadin (Tri a 19). we compared LTPs-positive patients and those sensitized to Tri a 19 in order to assess the difference in cofactors involved and in frequency of clinical presentation...

Objectives: Previous studies have reported a potential association of polyunsaturated fatty acids (PUFAs) levels with allergic disease risk and the possible benefit of PUFAs supplementation on allergic disease prevention. This study was performed to estimate the genetic association between PUFAs and allergic diseases using the method of both univariable and multivariable two-sample Mendelian randomization (MR). Methods: As indicators of the PUFAs levels, we included the omega-3, omega-6, docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), linoleic acid (LA), and the ratio of omega-6 to omega-3 (omega-6:3)...

BACKGROUND: Wheat-dependent exercise-induced anaphylaxis (WDEIA) is a serious and potentially life-threatening form of wheat allergy. Further episodes can only be prevented by avoiding wheat ingestion or avoiding exercise after wheat intake. Anaphylaxis may recur in some patients post-diagnosis. This study aimed to analyze the clinical features and management/outcomes of WDEIA in China. METHODS: We retrospectively analyzed the clinical characteristics, and laboratory testing of 197 patients with WDEIA...

Background: The clinical features of urticaria have not been fully illustrated. Objectives: To demonstrate clinical features of urticaria in different areas of southern and northern China. Methods: In this hospital-based multicenter study, outpatients with urticaria filled in a questionnaire during the initial visit and follow-up (once per week, lasting for a month). Results: Overall, 1,715 outpatients with urticaria with a mean age of 37...

LEAC-102 is an emerging drug extracted from the medicinal fungus Antrodia cinnamomea (AC), which is traditionally used to ameliorate fatigue and liver disorders arising from excessive alcohol consumption. AC has been used as a health product with an immunomodulatory function, but its anticancer effect has not been applied in clinical therapy as a drug. This first-in-human study examined the safety and tolerability of LEAC-102 as a new drug in healthy adults. This standard 3 + 3 dose-escalation study included 18 participants administered LEAC-102 at doses of 597...

A new episode of urticaria and/or angioedema can be an anxiety-inducing event for both the patient and the physician(s) seeing them in primary care, urgent care, or the emergency department. These events are commonly mistaken for "allergic" reactions and often mistreated. The most common causes of new onset urticaria in older children and adults, with or without angioedema, and normal vital signs or hypertension, are post-infection or acute idiopathic urticaria. These patients are not helped by systemic steroids, which may cause morbidity...

Early identification of cutaneous manifestations of alcohol and illicit drug use can aid in the diagnosis and management of these uses, as well as their sequelae. In addition, the effects of alcohol and illicit drug use on the skin can result in significant morbidity. Alcohol misuse can present with jaundice, pruritus, pigmentary alterations, urticaria, hair and nail changes, and oral changes. It is also a risk factor for skin cancer and infections. Vascular disturbances associated with alcohol misuse include telangiectasias, palmar erythema, caput medusae, and flushing...

We report a 16-year-old Japanese male with mugwort pollinosis in whom ingestion of wild grape juice and various vegetables caused recurrent general urticaria, abdominal pain, dyspnea, and loss of consciousness. A skin prick test demonstrated positive reactions to a wide variety of both non-heated and heated vegetables and fruits such as wild grape, bell pepper, onion, Chinese cabbage, tomato, eggplant, and broccoli. The serum immunoglobulin E levels (ImmunoCAP ISAC® ) for Art v 3, Pla a 3, Pru p 3, and Jug r 3, which are lipid transfer protein (LTP) homologs, were positive but those for Bet v 1 and Bet v 2 were negative...

Objectives: It is understudied how frequently adolescents use nutritional supplements (NS) and whether the corresponding behavior is associated with skin diseases that may cause unpleasant symptoms and disfigurement. The current study aimed to investigate the prevalence of NS use in Chinese college students and its association with inflammatory skin diseases. Methods: This was a university-based epidemiologic investigation that included 20,138 students who underwent dermatological examinations. A questionnaire survey was conducted to inquire about the use of NS along with related information...

Treatment of alcohol dependence with oral naltrexone may elicit an urticarial rash and angioedema. Acute spontaneous urticaria and an allergic reaction to an excipient represent important differential diagnoses.

BACKGROUND: Chronic spontaneous urticaria (CSU) is defined as the spontaneously appearing weals and/or angioedema for more than 6 weeks. Dietary habits can modulate the pathogenesis of CSU. However, dietary intakes of nutrients or food in CSU patients, compared with healthy controls, have not been examined in quality and quantity. METHODS: We evaluated dietary habits in adult Japanese patients with chronic spontaneous urticaria using a validated, brief-type self-administered diet history questionnaire and compared the results to those of age- and sex-matched healthy controls...

: Wine, beer, liquor, and spirits are widely consumed in many cultures across the globe, and for some individuals, ingestion, cutaneous contact, or other exposure can lead to dermatologic findings. However, there currently exist no comprehensive reviews on alcohol-related dermatitis. Herein, we will provide an overview of alcohol-related dermatitis and contact urticaria, including the epidemiology and clinical manifestations, potential allergens found in alcoholic beverages, testing approaches, and strategies for allergen avoidance...

Patients with chronic urticaria (CU) often ask about dietary modification. Research has indicated that specific dietary changes may be helpful in a subset of patients. Immunological food reactions are rare, but potential triggers of CU include those seen in certain settings, as in patients with a history of tick bites, a history of raw or marinated fish ingestion, or those with celiac disease. Nonimmunological food intolerances may also contribute, although mechanism of action is not well understood. Trials of pseudoallergen-free diets and low-histamine diets have resulted in partial remission in a subset of patients, while oral provocation testing has confirmed that some patients experience worsening of symptoms after ingestion of food additives, tomatoes, herbs, seafood, alcohol, and other foods...
