REVIEW
Rung-Chi Li, Kathleen M Buchheit, Jonathan A Bernstein
PURPOSE OF REVIEW: Progestogen hypersensitivity (PH) is a rare disorder which usually occurs in women of childbearing age with symptoms ranging from urticaria with or without angioedema, multiple organ involvement consistent with allergic anaphylaxis, to a spectrum of other non-evanescent skin eruptions. In this review, we present a clinical vignette of PH and discuss the clinical presentation and proposed pathomechanisms, diagnosis, and treatment of PH. RECENT FINDINGS: The hypersensitivity symptoms are associated with exogenous progestin exposure (e...

BACKGROUND: The Helicobacter pylori infection is linked to chronic urticaria in nearly 60% of patients. We studied clinicoepidemiologic features in patients with chronic urticaria with and without H. pylori infection. METHODS: Endoscopic antral biopsy for the rapid urease test (RUT) and histopathology, and serum IgG ELISA for H. pylori infection were performed in 150 patients (male:female ratio 1:2.4) of chronic urticaria aged 18-68 years. Clinicoepidemiologic features including age, gender, age of onset and duration, frequency and distribution of wheals, urticaria severity score, and systemic symptoms were analyzed in patients with and without H...

C1-inhibitor is a serine protease inhibitor (serpin) controlling complement and contact system activation. Gene mutations result in reduced C1-inhibitor functional plasma level causing hereditary angioedema, a life-threatening disorder. Despite a stable defect, the clinical expression of hereditary angioedema is unpredictable, and the molecular mechanism underlying this variability remains undisclosed. Here we report functional and structural studies on the Arg378Cys C1-inhibitor mutant found in a patient presenting reduced C1-inhibitor levels, episodically undergoing normalization...

Hereditary angioedema (HA) is a disabling and potentially fatal condition. The management of HA includes treatment of acute attacks, short-term prophylaxis to prevent an attack, and long-term prophylaxis to minimize the frequency and severity of recurrent attacks. In this article, we will present new therapeutic alternatives for long term prophylaxis. Glucocorticoids (GC) usage leads to a number of severe side-effects. In giant cell arteritis, the use of tocilizumab in conjunction with low doses of GC reduces the number of relapses...

Lingual hematoma is a severe situation, which is rare and endangers the airway. It can develop due to trauma, vascular abnormalities, and coagulopathy. Due to its sudden development, it can be clinically confused with angioedema. In patients who applied to the doctor with complaints of a swollen tongue, lingual hematoma can be confused with angioedema, in particular, at the beginning if the symptoms occurred after drug use. It should especially be considered that dystonia in the jaw can present as drug-induced hyperkinetic movement disorder...

Hereditary angioedema (HAE) is a rare disease and a serious health problem, globally and for affected patients and their families. The pathophysiological background is primarily a vascular reaction to an overshooting local production of bradykinin. Evidence-based recommendations are needed to inform and guide clinical decision makers. This is the first revision and update of the global guideline for the diagnosis and management of HAE[5]. It was developed by the World Allergy Organization (WAO) in collaboration with the European Academy of Allergy and Clinical Immunology (EAACI)...

Subcutaneous C1-inhibitor (HAEGARDA, CSL Behring), is a US Food and Drug Administration (FDA)-approved, highly concentrated formulation of a plasma-derived C1-esterase inhibitor (C1-INH), which, in the phase III Clinical Studies for Optimal Management in Preventing Angioedema with Low-Volume Subcutaneous C1-inhibitor Replacement Therapy (COMPACT) trial, reduced the incidence of hereditary angioedema (HAE) attacks when given prophylactically. Data from the COMPACT trial were used to develop a repeated time-to-event model to characterize the timing and frequency of HAE attacks as a function of C1-INH activity, and then develop an exposure-response model to assess the relationship between C1-INH functional activity levels (C1-INH(f)) and the risk of an attack...

BACKGROUND: Chronic spontaneous urticaria (CSU) is a frequent disorder with recurrent itchy wheals and/or angioedema. Despite the known effectiveness of omalizumab therapy, the relevant IgE antigens are largely unknown. Recently, increased rates of elevated levels of IgE towards Staphylococcus aureus enterotoxins (SEs) were described in CSU. AIM: To assess the prevalence and functional relevance of IgE to SEs in CSU. METHOD: We investigated serum levels of IgE against SEs in 49 CSU patients and in 15 CSU patients additional specific IgE to SE components and basophil histamine release (BHR)...

BACKGROUND/OBJECTIVE: The etiology and risk factors for angioedema remain poorly understood with causative triggers often going undiagnosed despite repeated reactions. The purpose of this study was to determine the relationship between inhalant allergen sensitization and angioedema. METHODS: A retrospective review of patients who had in vitro inhalant allergy testing from 2006 to 2010 was performed. Patients with a diagnosis of angioedema who underwent inhalant allergy testing were identified...

BACKGROUND: Angioedema is a condition of acute and extensive fluid accumulation in skin or mucosae due to increased blood vessel permeability. Angioedema can have several causes, including pregnancy. CASE DESCRIPTION: A healthy 33-year-old pregnant woman had acute, substantial swelling of the labia minora with no other symptoms. Based on clinical criteria, angioedema was diagnosed. Laboratory testing did not find any C1 inhibitor deficiency and hereditary angioedema was excluded for that reason...

Catamenial or cyclical anaphylaxis is a complex clinical syndrome with poorly reported incidence and prevalence in the literature review. The underlying mechanism is still a myth although a few proposed hypotheses are stated. Early recognition of these symptoms will bring optimal treatment and prevent unnecessary intubation and complications. Here, we present a 48-year-old woman without significant medical and family history with recurrent angioedema in the setting of catamenial anaphylaxis or cyclical anaphylaxis in the setting of progesterone hypersensitivity...

BACKGROUND: Up to 75% of patients with severe anaphylactic reactions after Hymenoptera sting are at risk of further severe reactions if re-stung. Venom immunotherapy (VIT) is highly effective in protecting individuals with ascertained Hymenoptera venom allergy (HVA) and previous severe reactions. After a 3- to 5-year VIT course, most patients remain protected after VIT discontinuation. Otherwise, a lifelong treatment should be considered in high-risk patients (eg, in mastocytosis). Several case reports evidenced that patients with mastocytosis and HVA, although protected during VIT, can re-experience severe and sometimes fatal reactions after VIT discontinuation...

BACKGROUND: Penicillin allergy is the most commonly reported antibiotic allergy. Avoidance of β-lactam antibiotics in hospitalized patients leads to the use of second-line therapies. OBJECTIVE: The utility of a penicillin allergy history algorithm (PAHA) and subsequent penicillin skin testing (PST) in transitioning hospitalized patients from second- to first-line antibiotic therapy is described. METHODS: Through an electronic medical record report, pharmacists identified adult inpatients with penicillin allergy receiving moxifloxacin, intravenous vancomycin, aztreonam, daptomycin, or linezolid, in which a β-lactam antibiotic was preferred...
