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...

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: 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: Randomized Controlled Trials showed that omalizumab exhibited a good safety and tolerability profile in patients with moderate-to-severe asthma. However, safety data of long-term treatment with omalizumab are scarce. Our aim was to assess the safety of omalizumab in patients under long-term treatment in a real-life setting. METHODS: Difficult-to-control asthmatic patients treated with omalizumab up to 9 years were retrospectively evaluated. Mild to severe adverse events any and reasons for discontinuation were recorded...

BACKGROUND: Allergy to Anisakis simplex (s.) is spreading due to the increased consumption of raw, smoked or marinated fish. In humans, Anisakis s. can directly attack the gastrointestinal mucosa, provoking a parasitosis known as anisakiasis, or giving rise to the formation of IgE and, finally, inducing IgE-mediated reactions like urticaria, angioedema and anaphylactic shock. During recent years, a dietary approach to Anisakis s. infestation has also been addressed. METHODS: A total of 620 patients with urticaria, angioedema, or both and a history of anaphylaxis following consumption of raw, smoked or marinated fish were recruited, evaluated for specific IgE levels to Anisakis s...

Alexa B Steuer, Sharon Scherl, Robin Ashinoff
Autoimmune progesterone dermatitis (APD) is a cyclical cutaneous reaction to progesterone, with symptoms that typically begin 3-10 days before the onset of menstrual flow and end 1-2 days into menses. The symptoms vary in severity from barely visible to anaphylaxis, but most often include an eczematous eruption, erythema multiforme, urticaria, folliculitis, and angioedema. This is a rare disorder with only a handful of documented cases. The pathogenesis of this condition remains unknown and significant variations in the presentation and severity of symptoms complicates its diagnosis...

The efficacy of oral acitretin in the systemic treatment of severe and recalcitrant dermatoses has been established in a large number of clinical trials. Its mucocutaneous and ocular adverse reactions are common or relatively common, whereas systemic side effects are either uncommon or rare and include teratogenesis, hyperlipidemia, hepatotoxicity, intracranial hypertension, myopathy, and peripheral neuropathy. Angioedema is a term used to describe an acute, solitary or multiple, circumscribed, and non-pitting mucocutaneous swelling that affects the dermis and the subcutaneous tissue, lasts 24 to 72 hours, and may become potentially life-threatening when the pharynx and/or the larynx are involved...
