BACKGROUND: To estimate health-related quality-of-life changes in patients with hereditary angioedema due to C1-inhibitor (C1-INH) deficiency who received subcutaneous C1-INH with recombinant hyaluronidase (rHuPH20) for attack prophylaxis in a randomized, double-blind, dose-ranging, cross-over study. METHODS: Patients with type I/II hereditary angioedema received 1000 U of C1-INH with 24,000 U of rHuPH20 or 2000 U of C1-INH with 48,000 U of rHuPH20 every 3-4 days for 8 weeks and then crossed over for another 8-week period...

Autoimmunity is an important cause of disease both in the central and peripheral nervous systems. Aetiologies and clinical manifestations are complex and heterogeneous. Inappropriate control of complement activation at inappropriate sites has been recognized as a major determinant in several neurological conditions, including Guillain-Barré syndrome and neuromyelitis optica. In each case pathogenesis is thought to be associated with generation of autoantibodies which upon binding guide activation of the complement system to self-tissue...

BACKGROUND Miller Fisher Syndrome is characterized by the clinical triad of ophthalmoplegia, ataxia, and areflexia, and is considered to be a variant of Guillain-Barre Syndrome. Miller Fisher Syndrome is observed in approximately 1-5% of all Guillain-Barre cases in Western countries. Patients with Miller Fisher Syndrome usually have good recovery without residual deficits. Venous thromboembolism is a common complication of Guillain-Barre Syndrome and has also been reported in Miller Fisher Syndrome, but it has generally been reported in the presence of at least one prothrombotic risk factor such as immobility...

Angioedema (AE) of the upper airways is a severe and potentially life-threatening condition. The incidence has been increasing in the past two decades, primarily due to increased use of medications inhibiting the degradation of vasoactive peptides. Acquired angioedema related to angiotensin-converting enzyme inhibitors (ACEI-AAE) is well known, but other pharmaceutical agents also affect the degradation of bradykinin and substance P. We present a middle-aged man with recurrent episodes of severe AE of the oral cavity, hypopharynx and larynx due to pharmacological inhibition of dipeptidyl peptidase IV...

BACKGROUND: Hereditary angioedema caused by C1-inhibitor deficiency (C1-INH-HAE) is a rare, autosomal dominant disorder. C1-INH-HAE is characterized by edema-formation, which may occur in response to stress. The individual's response to stress stimuli is partly genetically determined. Activation of the hypothalamic-pituitary-adrenal axis results in the release of cortisol. In turn, the secreted gluco- and mineralocorticoids affect the metabolism, as well as the cardiovascular and immune systems...

Sacubitril-valsartan is a combination drug that contains the neprilysin inhibitor sacubitril and angiotensin II receptor blocker valsartan. In 2015, the US Food and Drug Administration approved sacubitril-valsartan for treatment of heart failure patients with reduced ejection fraction and New York Heart Association class II-IV symptoms following a large, Phase III clinical trial (PARADIGM-HF) that demonstrated a 20% reduction in the combined primary end-point of death from cardiovascular cause or hospitalization for heart failure compared to enalapril...

Hannah Fernandez-Gotico, Tiffany Lightfoot, Melissa Meighan
BACKGROUND AND PURPOSE: The approved treatment by the Food and Drug Administration for acute ischemic stroke is intravenous tissue-type plasminogen activator (IV tPA). After IV tPA administration, patients are monitored for adverse events using an American Heart Association/American Stroke Association guideline instituted in 1996. There is limited evidence describing the safest and most efficient method to monitor patients during the first 24 hours after tPA administration. Although the overall rates of adverse events have been reported, the time when patients may be at most risk for an event has not been studied...

Angio-oedema is a transitory, localized, noninflammatory oedema of subcutaneous tissue or mucous. When the oedema affects the mouth, lips, tongue or larynx, it can result in fatal asphyxiation in the absence of specific treatment. Oedema secondary to plasma extravasation is usually mediated by either histamine or bradykinin. As laboratory tests are not available in an emergency setting, the implicated mediator cannot be readily determined. The challenge for the emergency physician is to determine the aetiological type, evaluate severity and initiate adapted treatment by means of a structured approach...

INTRODUCTION: Mansonella perstans is a human filarial parasite transmitted by biting midges (Diptera: Ceratopogonidae) belonging to the genus Culicoides and it is widely spread in sub-Saharan Africa. While most cases are asymptomatic, mansonelliasis can be associated with angioedema, arthralgia, swellings, pain in the scrotum or in serous cavities such as the pleura, the peritoneum, the pericardium, etc. Mansonelliasis can be really hard to treat, but it has been shown that an intensive treatment using albendazole can clear the parasite...

Kun Gou, Thomas J Pence
Angioedema is a tissue swelling pathology due to rapid change in soft tissue fluid content. Its occurrence in the trachea is predominantly localized to the soft mucous tissue that forms the innermost tracheal layer. The biomechanical consequences, such as airway constriction, are dependent upon the ensuing mechanical interactions between all of the various tissues that comprise the tracheal tube. We model the stress interactions by treating the trachea organ as a three-tissue system consisting of swellable mucous in conjunction with nonswelling cartilage and nonswelling trachealis musculature...

Hereditary angioedema (HAE) is a rare and potentially life threatening autosomal dominant disease characterized by recurrent episodes of cutaneous and mucosal oedema. It results from reduced expression or loss of function of CI-esterase inhibitors (C1-INH). As opposed to the more common histamine-mediated angioedema, HAE does not respond well to conventional treatments with anti-histamines, steroids and adrenaline. Early recognition and timely intervention with the correct treatment are crucial particularly preventing airway obstruction...

The Adverse Drug Reaction (ADR) to a commonly prescribed anti-microbial can pose a major public health problem. The authors report a rare case of 24-year-old young lady who presented with angioedema of lips after ingestion of Ofloxacin, prescribed to her for treatment of loose motions. Fluoroquinolones are widely prescribed antibiotics for various disease conditions. The history, clinical examination and normal laboratory parameters led to the diagnosis of ofloxacin induced hypersensitivity reaction and the patient was successfully treated with corticosteroids and antihistamines...

BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDS) are among the most common causes of drug hypersensitivity (HS) reactions. The diagnosis is based on a careful clinical history, and provocation tests are considered the gold standard for diagnosis. Skin tests have some value to study reactions to pyrazolones. Laboratory investigations are mostly used for research purposes. Different phenotypes have been described. OBJECTIVE AND METHODS: Our aim was to describe the most common clinical manifestations of NSAID HS in a large population of adult patients, the drugs involved, the association with previously described risk factors, and the outcome of diagnostic procedures...

Factor XII (FXII) is a plasma protease that has emerged in recent years as a potential target to treat or prevent pathological thrombosis, to inhibit contact activation in extracorporeal circulation, and to treat the swelling disorder hereditary angioedema. While several protein based inhibitors with high affinity for activated FXII (FXIIa) were developed, the generation of small molecule inhibitors has been challenging. In this work, we have generated a potent and selective FXIIa inhibitor by optimizing a peptide macrocycle that was recently evolved by phage display (Ki = 0...

Hereditary angioedema (HAE) is a rare disease, little known to the medical and dental community, but with a growing rate of hospitalization over the years. HAE is due to a deficit/dysfunction of C1 esterase inhibitor which leads to an increase in vascular permeability and the appearance of edemas widespread in all body areas. The airways are the most affected and laryngeal swelling, which can occur, it is dangerous for the patient's life, is also a sensitive spot in our daily practice, therefore, it is also important to be aware of all the signs of this disease...

Unfortunately, the treatment of numerous otolaryngological diseases often lacks of evidence base because appropriate studies are missing. Whereas sufficient high-quality trials exist for the specific immunotherapy of allergic rhinitis and in a limited measure also for the angiotensin-converting enzyme inhibitor induced angioedema, the evidence for Menière's disease or for pharmacotherapy of postoperative laryngeal edema is rather poor. This contribution will discuss the trial situation and evidence of the respective diseases...

Hereditary angioedema due to C1 inhibitor deficiency (C1-INH-HAE) is a disabling and life-threatening disease for which plasma-derived C1 inhibitor (pdC1-INH) is an effective treatment. Poor responses to pdC1-INH are rare. The aim of this prospective study was to evaluate the pharmacokinetics and pharmacodynamics of C1 inhibitor (C1-INH) in a C1-INH-HAE patient with poor response to treatment to investigate the mechanism underlying poor response to pdC1-INH. Seventeen C1-INH-HAE patients with normal responses to treatment served as retrospective controls...

In 1960, Dr. Bayard Clarkson described a woman experiencing sporadic, recurrent episodes of shock and anasarca. Plasma from an acute attack induced a "shock"-like syndrome when injected into rats. The enigmatic "Systemic Capillary Leak Syndrome" (SCLS) named for Dr. Clarkson is characterized by transient and severe, but reversible, hemoconcentration and hypoalbuminemia due to leakage of fluids and macromolecules into tissues. Although < 500 cases of SCLS have been reported in the literature since 1960, the condition is probably under-diagnosed due to lack of awareness and a high mortality without treatment...
