Basophil Activation Test for Allergy Diagnosis.

J Vis Exp 2021 May 31(171). Epub 2021 May 31.

Allergy Unit, Hospital Regional Universitario de Málaga; Allergy Research Group, Instituto de Investigación Biomédica de Málaga-IBIMA; Departamento de Medicina, Universidad de Málaga; Nanostructures for Diagnosing and Treatment of Allergic Diseases Laboratory, Andalusian Center for Nanomedicine and Biotechnology-BIONAND.

The basophil activation test (BAT) is a complementary in vitro diagnostic test that can be used in addition to clinical history, skin test (ST), and specific IgE (sIgE) determination in the evaluation of IgE-mediated allergic reactions to food, insect venom, drugs, as well as some forms of chronic urticaria. However, the role of this technique in the diagnostic algorithms is highly variable and not well determined. BAT is based on the determination of basophil response to allergen/drug cross-linking IgE activation through the measurement of activation markers (such as CD63, CD203c) by flow cytometry. Read More

Research on Characteristic of Chronic Spontaneous Urticaria Based on Multiscale Entropy.

Comput Math Methods Med 2021 25;2021:6691356. Epub 2021 May 25.

College of Mathematical Sciences, Harbin Engineering University, Harbin 150001, China.

Chronic spontaneous urticaria (CSU) is a common skin disease which symptom is local pruritus and pain. In medicine, researchers take a certain point that the brain is the control center of CSU, but in previous experiments, the researchers found that cerebellum also had a certain effect on CSU. In order to find out the influence of CSU in the brain and cerebellum, we collected the brain resting-state fMRI data from 40 healthy controls and 32 CSU patients and used DPABI to preprocess.

What's New in the Treatment of Urticaria and Angioedema.

J Allergy Clin Immunol Pract 2021 Jun;9(6):2170-2184

Department for Children and Adolescents, University Hospital Frankfurt, Goethe University, Theodor-Stern-Kai 7, Frankfurt, Germany.

Chronic urticaria and angioedema are diseases often managed by Allergy and Immunology specialists. Recent international guidelines have outlined a stepwise approach to management of patients using dose escalation of second-generation antihistamines followed by use of omalizumab and finally cyclosporine in more refractory cases. In select patients (those with refractory chronic urticaria), nonbiologic alternative medications with anti-inflammatory or immunosuppressant activity may be considered. Read More

Triggers of Exacerbation in Chronic Urticaria and Recurrent Angioedema-Prevalence and Relevance.

J Allergy Clin Immunol Pract 2021 Jun;9(6):2160-2168

Clinical Faculty, University of Texas Southwestern Medical School, Allergy and Asthma Specialists, Dallas, Texas. Electronic address:

Patients with urticaria and angioedema often have triggers that cause an outbreak or a swelling episode or worsen their chronic condition. Exploring these factors with each patient may result in better understanding and control of their disease. Patients should be advised to avoid known triggers, if feasible, or prepare to prevent or control an exacerbation with appropriate pretreatment if avoidance is not possible. Read More

How to Measure Disease Activity, Impact, and Control in Patients with Recurrent Wheals, Angioedema, or Both.

J Allergy Clin Immunol Pract 2021 Jun;9(6):2151-2157

Division of Clinical Immunology and Allergy, Department of Medicine, McMaster University, Hamilton, ON, Canada.

Chronic spontaneous urticaria and chronic inducible urticaria are characterized by wheals, angioedema, or both, whereas other conditions such as hereditary angioedema present only with angioedema. The unpredictability of outbreaks, disfigurement, pruritus, and associated sleep and work disturbance can cause a significant impact on quality of life (QoL). Significant breakthroughs in the understanding of these conditions in recent years have led to the development of novel therapies. Read More

Divergent PGD and leukotriene C metabolite excretion following aspirin therapy: Ten patients with systemic mastocytosis.

Prostaglandins Other Lipid Mediat 2021 Aug 21;155:106563. Epub 2021 May 21.

Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN, United States.

Aspirin-exacerbated respiratory disease and some cases of chronic idiopathic urticaria are disorders in which increased baseline urinary excretion of leukotriene(LT)E4 further increases following aspirin administration. Increased urinary excretion of the metabolites of prostaglandin D2, 11β-prostaglandin(PG)F2α and (2,3-dinor)-11β-PGF2α, have been documented in systemic mastocytosis (SM) and in mast cell activation syndrome (MCAS). Symptoms due to increased baseline and/or episodic release of PGD2 can be prevented with aspirin, an inhibitor of cyclooxygenase (COX)1 and COX2. Read More
