    Full Text Available O angioedema adquirido é causado por diferentes medicamentos e doenças linfoproliferativas, e tem sido raramente relacionado com a presença de doenças autoimunes. Descrevemos aqui uma paciente de 47 anos com lúpus eritematoso sistêmico (LES com envolvimento cutâneo importante que desenvolveu angioedema recorrente localizado em face incluindo lábios e pálpebras, membros superiores e tórax, não acompanhado de urticária e com dosagem do inibidor de C1 esterase reduzida. A utilização de antimaláricos, glicocorticoides e pulsoterapia com metilprednisolona associada ao uso de azatioprina não determinou melhora. A paciente utilizou também danazol sem sucesso, e apresentou resposta clínica somente após ter sido submetida a múltiplas sessões de plasmaferese, ocorrendo inclusive resolução de extenso angioedema na mucosa do trato gastrointestinal.Acquired angioedema is caused by different drugs and lymphoproliferative diseases, and rarely it has also been related to the presence of auto-immune disorders. We report the case of a 47 year old female with systemic lupus erythematosus (SLE and severe cutaneous involvement who developed recurrent localized angioedema of the face, including lips and eye lids, upper limbs, and thorax, not associated with urticaria, and with reduced levels of C1 esterase inhibitor. Treatment with antimalarials, glucocorticoids, and pulse therapy with methylprednisolone associated with azathioprine did not improve her condition. The patient was also unsuccessfully treated with danazol, and she only showed clinical response after several sessions of plasmapheresis, including resolution of the extensive edema of the gastrointestinal tract.

    Angioedema may be an overlooked common disease. Angioedema comprises the idiopathic, the allergic, pseudo allergic, the physical form as well as the hereditary form. Diagnosis is simple when symptoms are classical (lips, eyes and tongue) but might be missed if symptoms are nonspecific such as dizziness or dyspnoea. However, the most striking observation reviewing the literature is the absence of original research on angioedema considering the high prevalence of the disease. From a patient and physician perspective more information and research on angioedema is needed.

    2017-08-01

    Angioedema is frequently categorized into histamine- or bradykinin-mediated disease. It is critical to determine the underlying mediator of symptoms as it directs treatment. Histaminergic angioedema is the most frequent cause of angioedema. It is classified as either acute (lasting 6 weeks). It is further classified into angioedema presenting with or without urticaria. Some patients with acute angioedema may have disease that becomes chronic. Mast cells and basophils are central to the underlying pathophysiology of histamine-mediated angioedema. The underlying treatments of histamine-mediated angioedema are antihistamines, corticosteroids, and epinephrine. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Hereditary angioedema — a rare disease caused by a congenital deficiency of C1-inhibitor. Clinical manifestations of the disease — recurrent episodes of angioedema, which manifest in childhood or adolescence, more often localized in the subcutaneous tissue (limbs, face, trunk, genitals or submucosa (intestine, larynx. Swellings of the larynx are potentially harmful to the patient’s life. Early detection enables to carry out timely appropriate treatment and prevention of angioedema. The paper presents a case of hereditary angioedema with manifestation in early childhood. The case study demonstrates the complexity of diagnosis and treatment of hereditary angioedema.

    The aims of this study are to update the clinician on current understanding of angioedema as it presents in the pediatric population and to review proper diagnostic techniques and treatment modalities for various types of angioedema. Angioedema is still best classified by whether it is likely histaminergic or kinin-mediated. New guidelines have been published around the world to help diagnose and treat both forms (urticaria/angioedema and hereditary angioedema). The vast majority of the studies on treatment have been conducted in the adult population; however, there are data available in the pediatric population. In the realm of hereditary angioedema, there are multiple new therapies that have been studied in the pediatric population (down to 2 years in some studies) in recent years and offer the clinician options for treatment. Angioedema (whether occurring with or without urticaria) is common in the pediatric population. The majority of the recent studies has been conducted in hereditary angioedema, and now, the clinician should have various options to treat all forms of angioedema. Many treatment options, especially for hereditary angioedema, are further being examined specifically in the pediatric population.

    Hereditary angioedema is an autosomal-dominant deficiency of C1 inhibitor--a serpin inhibitor of kallikrein, C1r, C1s, factor XII, and plasmin. Quantitative or qualitative deficiency of C1 inhibitor leads to the generation of vasoactive mediators, most likely bradykinin. The clinical syndrome is repeated bouts of nonpruritic, nonpitting edema of the face, larynx, extermities, and intestinal viscera. Recently, investigators, physicians, and industry have demonstrated a renewed interest in the biology and treatment of hereditary angioedema. Investigators have generated a C1INH-/- mouse model that has demonstrated the importance of the contact activation system for hereditary angioedema-related vascular permeability. An interactive database of mutations is available electronically. Investigators have continued exploration into mRNA/protein levels. The proceedings of a recent workshop have been impressive in the scope and depth. Clinicians have produced consensus documents and expert reviews. The pharmaceutical industry has initiated clinical trails with novel agents. Hereditary angioedema is often misdiagnosed and poorly treated. Diagnosis requires careful medical and family history and the measurement of functional C1 inhibitor and C4 levels. Attenuated androgens, anti-fibrinolytics, and C1 inhibitor concentrates are used for long-term and preprocedure prophylaxis, but have significant drawbacks. C1 inhibitor concentrates and fresh frozen plasma are available for acute intervention. The mainstays of supportive care are airway monitoring, pain relief, hydration, and control of nausea. New agents such as recombinant C1 inhibitor, kallikrein inhibitors, and bradykinin inhibitors may offer safer and more tolerable treatments.

    Full Text Available Hereditary Angioedema is a dominantly inherited disease. Routine screening of autoantibodies (AAB is not recommended for individuals with Hereditary Angioedema; however, prevalence of these antibodies in Hereditary Angioedema patients is not well documented. We aim to determine the prevalence of AAB so that individuals at risk of developing autoimmune diseases can be identified. Fifteen patients with Hereditary Angioedema attended at Clementino Fraga Filho University Hospital accepted to participate in this study. Prevalence of AAB was 40%. Our data indicate high prevalence of AAB in patients with Hereditary Angioedema. Large-scale studies should be considered to determine the significance of these AAB in the follow-up care of patients with Hereditary Angioedema.O Angioedema Hereditário é uma doença autossômica dominante.

  13. Bradykinin-mediated angioedema.

    2016-01-01

    Angioedema and urticaria often constitute a challenge in daily clinical practice. They may either co- -occur or present as independent conditions. They are characterized by a complex pathomechanism, and their symptoms may be triggered by diverse factors. These differences are crucial for developing a successful treatment regimen. Both conditions may have an allergic origin (immunoglobulin [Ig] E and non-IgE-related), usually induced by histamine, or a nonallergic one, such as bradykinin-mediated angioedema in patients with C1 inhibitor (C1-INH) deficiency or angioedema induced by certain drugs (eg, angiotensin-converting enzyme inhibitors). Currently, we distinguish 5 types of nonallergic angioedema: hereditary angioedema (HAE) due to C1-INH deficiency, acquired angioedema (AAE), and angioedema induced by the renin-angiotensin-aldosterone system, all of which are mediated by bradykinin, as well as pseudoallergic angioedema and idiopathic angioedema. Bradykinin-mediated angioedema (eg, laryngeal angioedema) may be life-threatening because of resistance to corticosteroids and antihistamine drugs. C1-INH concentrates are the drugs of choice in the treatment of HAE and AAE. In recent years, some new drugs have been introduced in the treatment of bradykinin-mediated angioedema, such as bradykinin B2-receptor antagonist, icatibant, and kallikrein inhibitor, ecallantide, which allow to improve treatment outcomes.

    2014-01-01

    Urticaria, also known as hives, and angioedema, where the swelling occurs below the skin instead of on the skin, are extremely common but there is a misconception that the most likely cause is an allergic reaction. Chronic urticaria in particular is rarely due to allergy. Equally for angioedema, many will consider the exceptionally rare hereditary angioedema (HAE), but in fact other medical causes are the most likely, in particular the use of angiotensin-converting enzyme inhibitor (ACE-I) drugs. Approximately 3-5% of patients receiving ACE-I will develop angioedema at some time in the course of their treatment.1 Stress is a major contributor to both chronic urticaria and recurrent angioedema. Treatment needs to focus on the use of long-acting, non-sedating, antihistamines. Corticosteroids may be used acutely but not long term.

    Full Text Available Angioedema is a serious adverse drug reaction that can rarely be associated with trifluoperazine treatment. We present the case of a 44-year-old male with an established diagnosis of schizoaffective disorder, for which trifluoperazine therapy was considered. He presented to the emergency department with bilateral lower limb oedematous painful erythematous swelling that eased off completely when trifluoperazine was stopped. The possibility of allergic reaction, such as angioedema, should always be kept in mind by psychiatrists and mental health professionals when prescribing trifluoperazine antipsychotic.

    Angiœdema (AE) is the clinical expression of urticaria (U) which occurs when urticaria is located within the subcutis. It is a syndrome characterized by a sudden and limited subcutaneous and/or submucous swelling. The updated classification of urticaria distinguishes acute and chronic urticaria. Chronic urticaria is spontaneous (CSU) or inducible (CIU). Angioedema in chronic urticaria is rarely allergic, but most of the time caused by a non-specific histamine release from activated mast-cell (non IgE mediated reaction). Angioedemas are recurrent, concomitant or not with wheals. They appear skin-coloured, sometimes slightly rosy, non-inflammatory, and more painful than itchy. They are transient, ephemeral, migrant, last most of the time a few hours (Angioedema can be elicited or worsened by physical factors (cold urticaria, exercise, heat, solar, vibratory, aquagenic, delayed pressure urticaria…) and /or drugs (as aspirin, nonsteroid anti-inflammatory drugs, morphine, antibiotics…). The treatment of histaminergic angioedemas of chronic urticaria is based on modern second generation antihistamines (anti H1). In allergic acute urticaria only, additional treatment for anaphylaxis can be used if needed (grade 2 to 4). In chronic urticaria, steroids should be avoided : they can make symptoms worse and long-lasting because of corticosteroid dependence. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Full Text Available Abstract Women with hereditary angioedema (HAE are more likely to be symptomatic that men. Hormonal factors (puberty, contraception, pregnancy,.... play a significant role in the precipitation or worsening of the condition in women. So, combined contraceptive pills are not indicated and progestogen pill must be preferred. During pregnancy, attack rate can increase (38-48% of women. C1Inhibitor concentrate and tranexamic acid can be used during pregnancy. Attenuated androgens for long term prophylaxis are effective but side effects appear more often in female patients. These side effects are dose dependant and can be attenuated by titrating the dose down the lowest effective level.

  3. The Clinical Evaluation of Angioedema.

    2017-08-01

    The clinical evaluation of angioedema is reliant on obtaining a thorough patient and family history with an assessment of risk factors and presenting symptoms unique to each subtype. It is important to distinguish between angioedema with and without urticaria as a primary step in the evaluation; thereafter, laboratory parameters and investigations allow for subsequent stratification. There is a significant disease burden associated with angioedema and thus it is essential for health care practitioners to establish a prompt and accurate diagnosis, and a comprehensive care plan that addresses the patient's physical and mental well-being alike.

    2013-01-01

    Angiotensin-converting enzyme inhibitors (ACEI) are commonly prescribed for blood pressure control and renal protection. ACEI angioedema is a common problem in patients who are taking ACEI, although, in most cases, the disorder is self-limited, and spontaneous episodes of apparently unprovoked angioedema stop with the discontinuation of the medication. In a subset of patients, hospitalization and even intubation are required for airway protection. The diagnosis is made clinically. There are no laboratory studies that establish the diagnosis. However, such investigations help exclude alternative diagnoses as the cause for the patient's presentation. Conventional treatment with regimens used to control allergic angioedema is ineffective in this condition. The mechanism of ACEI-induced angioedema is thought to be related to its effect on the kallikrein-kinin system. Kallikrein is a protease that converts high-molecular-weight kininogens into kinins, primarily bradykinin. Medications recently developed, primarily icatibant and ecallantide, to control hereditary angioedema, a disorder also associated with kallikrein-kinin activation, have been used to treat ACEI angioedema with some success. The efficacy of these agents and their optimal use remains to be established by randomized and placebo controlled trials. Copyright © 2013 American Academy of Allergy, Asthma & Immunology.

    Full Text Available Resumo: O pulmão é uma interface particular entre o antigénio e o sangue circulante. É alvo de acções extrínsecas/intrínsecas e é particularmente vulnerável à agressão por agentes em circulação. Tal como a superfície mucosa, é um local de intensa acção imune, permitindo a expressão antigénica através da recirculação linfocitária. Assim, geram-se reacções locais, inflamatórias, ao antigénio. A imagiologia tem um papel importante no diagnóstico de doenças pulmonares imunológicas. Este grupo inclui as doenças pulmonares auto-imunes. A telerradiografia torácica tem muitas vantagens, mas também algumas limitações. A tomografia computorizada (TC constituiu uma revolução na imagiologia de doenças pulmonares, sendo a técnica de alta resolução uma mais-valia no estudo do interstício. Esta técnica permite uma maior exactidão do que a radiografia convencional no diagnóstico de patologias pulmonares, como as patologias auto-imunes. Abstract: The lung is a unique interface between the antigen and the circulating blood volume. It is submited to extrinsic/intrinsic challenges and is particularly vulnerable to circulating insulting agents. It is a site of intense immune surveillance, allowing antigen sampling to expand the immunologic repertoire through lymphocyte recirculation. In addition, local inflammatory reactions to antigens are generated.Imaging has an important role in diagnosis of patients with immunologic lung diseases. This group includes autoimmune lung diseases. There are many advantages of plain chest radiography but also significant limitations. It was a revolution in imaging of lung diseases with Computed Tomography (CT, being high resolution an important help in pulmonary interstitium study. This technique has a higher diagnostic accuracy than the conventional chest X-ray both in the detection and the diagnosis of lung diseases, such as autoimmune lung diseases.

    Full Text Available Dermatoses bolhosas autoimunes são doenças cuja manifestação cutânea primária e fundamental consiste em vesículas e bolhas. Classificam-se conforme a localização da bolha, em intraepidérmica e subepidérmica. Os pacientes produzem autoanticorpos contra estruturas específicas da pele detectáveis por técnicas de imunofluorescência, immunobloting e Elisa. Os recentes avanços da biologia molecular e celular têm permitido conhecer esses autoantígenos, contra os quais os pacientes se sensibilizam e que estão localizados na epiderme ou na junção dermoepidérmica. São doenças de baixa incidência, porém de elevada morbidade e por vezes letais. O objetivo deste trabalho é revisar e descrever os progressos nos conhecimentos de quatro doenças vésico-bolhosas autoimunes: pênfigo foliáceo endêmico (fogo selvagem, pênfigo vulgar, penfigóide bolhoso e dermatite herpetiforme.Autoimmune bullous dermatoses are diseases in which blisters and vesicles are the primary and fundamental types of skin lesion. Their classification is based on the location of the blister: intraepidermal and subepidermal. Patients produce autoantibodies against self-specific structures of the skin detectable by immunofluorescence techniques, immunoblotting and ELISA. Recent advances in molecular and cellular biology have brought to knowledge these self-antigens, against which patients are sensitized, and which are found in epidermis or in the dermo-epidermal junction. These are low incidence, but high morbidity diseases that may be fatal. The aim of this article is to review and describe the progress of four autoimmune vesiculobullous disorders: endemic pemphigus foliaceous (wild fire, pemphigus vulgaris, bullous pemphigoid and dermatitis herpetiformis.

    2014-10-01

    Angiotensin inhibitors have been extensively evaluated in clinical trials and have demonstrated significant reductions in morbidity and mortality following myocardial infarction and stroke, as well as in patients with heart failure or who are at risk of cardiovascular disease. Further, both angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are frequently prescribed for the treatment of hypertension and to preserve renal function in patients with diabetes mellitus and chronic kidney disease. Angioedema is a known, but rare, adverse effect of ACEIs and ARBs. Therefore, it is important for clinicians to have a thorough understanding of risks and benefits of prescribing these medications, particularly in patients with a history of angioedema. This review describes the literature evaluating the incidence and cross-reactivity of angioedema with ACEIs and ARBs in order to provide guidance for clinical decision making. © The Author(s) 2014.

  10. Recent Advances in Drug-Induced Angioedema

    Directory of Open Access Journals (Sweden)

    Naoko Inomata

    2012-01-01

    Full Text Available Angioedema is the end result of deep dermal, subcutaneous and/or mucosal swelling, and is potentially a life- threatening condition in cases where the pharynx or larynx is involved. Drug-induced angioedema has been reported to occur in response to a wide range of drugs and vaccines. Drug-induced angioedema, like other cutaneous drug reactions, has been reported to be most frequently elicited by beta-lactam antibiotics and nonsteroidal anti-inflammatory drugs, although reliable data from epidemiologic studies are scarce. Recent reports suggested an increasing role of angiotensin-converting enzyme inhibitors (ACEIs in the causation of life- threatening angioedema. ACEI-related angioedema is never accompanied by urticaria and occurs via a kinin- dependent mechanism. ACEI-related angioedema not only can start years after beginning the treatment, but it can then recur irregularly while under that treatment. Furthermore, allergy tests are unreliable for the diagnosis of ACEI-related angioedema, and so the relationship between angioedema and ACEIs is often missed and consequently quite underestimated. Accordingly, better understanding of the kinin-dependent mechanism, which is particular to angioedema, is necessary for the appropriate management of drug-induced angioedema.

    2018-02-01

    We present a 13-year-old male childallergic to three different plants (Salvia officinalis, Mentha piperita and Origanum onites L.) of Lamiaceae family. The patient developed angioedema 20-30 minutes after eating chicken meat with cheddar cheese. There was no history of allergy. Oral food challenge (OFC) with both cheddar cheese and chicken meat was negative. Skin tests for inhalant allergens were negative. 3 weeks later, the patient was admitted with angioedema after drinking sage tea. OFC with sage was applied and angioedema was observed. It was recognized that the first trigger, chicken meat with cheddar cheese, included oregano (Origanum onites L.). OFC for oregano was positive. Prick to prick test for Lamiaceae herbs (oregano, sage, mint) was performed. A positive reaction was observed only to mint. OFC was repeated with fresh mint and angioedema developed after 16 hours. Diagnose of Lamiaceae allergy is complicated and cross-sensitivity is common. Skin prick test (prick to prick)revealed a positive response only to mint but not to oregano and sage. Commercial radioallergosorbent (RAST) tests are available only for a few members of the family. Finally, thediagnose is based mainly on OFC. Spices from Lamiaceae group should be considered as potential triggers of allergic reactions.

    Urticaria, also known as hives, may affect up to 20% of the population at some time in their lives. Urticaria is characterized by extreme pruritus and described as erythematous, raised, circumscribed lesions with central pallor that blanch with pressure. The pathogenesis of urticaria involves mast cell activation, with subsequent release of histamine and other vasoactive mediators, leading to increased vascular permeability of postcapillary venules and development of edema, erythema, and pruritus. Urticaria is closely associated with angioedema in 40% of individuals; ∼10% of patients experience angioedema without urticaria. Urticarial lesions often are generalized with multiple lesions in no specific distribution; angioedema tends to be localized, commonly affecting the face (periorbital and perioral regions), tongue, uvula, soft palate or larynx, extremities, and genitalia. Urticaria is subdivided into acute and chronic urticaria based on duration of symptoms. Acute urticaria lasts products, medications (aspirin, nonsteroidal anti-inflammatory drugs, and antibiotics), or insect stings. Urticaria lasting >6 weeks is designated as chronic urticaria, and an etiology is seldom identified and thus considered idiopathic. Chronic urticaria may have an autoimmune basis. There is a well-documented association between autoimmune hypothyroidism (Hashimoto's disease) and urticaria and angioedema with higher incidence of antithyroid (antithyroglobulin and antiperoxidase) antibodies in these usually euthyroid patients. Furthermore, studies have revealed a circulating IgG antibody directed against the IgE receptor (F(Cε)RIα) or IgE in 40-60% of patients with chronic urticaria. Histamine 1-receptor antagonists (antihistamines) are initial therapy.

    There has been no separate study investigating angioedema without urticaria (Aw/oU) exclusively in children so far. The purpose of this study was to investigate the frequency, clinical presentation, etiology, management and follow-up of Aw/oU in children. This is a prospective study that included all consecutive patients with a history of Aw/oU referred to our clinic between January 2011 and May 2012. A standard diagnostic and therapeutic algorithm was applied to all patients. The frequency of Aw/oU was found to be 1.6% during the study period. An etiological factor could be found in only 45 patients (49%). The causes of Aw/oU were infection (21%), allergy (14%), thyroid autoimmunity (TA)-related (8%) and nonsteroid anti-inflammatory drug hypersensitivity (6%), and idiopathic angioedema (51%). There was no hereditary type I, II or acquired type of angioedema or rare syndromes associated with Aw/oU. The median follow-up was 16 months (range: 12-30 months). Antihistamine prophylaxis was initiated at therapeutic doses in 20 patients with frequently recurrent angioedema due to idiopathic and euthyroid TA-related Aw/oU for 3 months. These patients responded to antihistamine prophylaxis for 3 months. Four patients relapsed after cessation of prophylaxis at the end of 3 months. Antihistamine prophylaxis was prolonged to 6 months in three patients and to 9 months in one patient. Angioedema without urticaria in children is a rare condition and no etiology can be identified in half of them. Antihistamine treatment alone is sufficient, and prognosis is good in recurrent non hereditary cases in a short-term follow-up period. © 2013 John Wiley & Sons A/S.

    Due to marked heterogeneity of clinical presentations, comprehensive knowledge of angioedema phenotypes is crucial for correct diagnosis and choosing the appropriate therapeutic approach. One of the ways to a meaningful clinical distinction can be made between forms of angioedema occurring "with or without wheals." Angioedema with wheals (rash) is a hallmark of urticaria, either acute or chronic, spontaneous or inducible. Angioedema without wheals may still be manifested in about 10 % of patients with urticaria, but it may also occur as a separate entity. Several classifications of angioedema as part of urticaria were published over time, while a latest one, released in 2014 (HAWK group consensus, see below), provided a classification of all forms of "angioedema without wheals" distinct from urticaria, which will be the focus of the present review. At this time, the HAWK consensus classification is the best in terms of covering the pathophysiology, mediators involved, angioedema triggers, and clinical expression. According to this classification, three types of hereditary angioedema (genetic C1-INH deficiency, normal C1-INH with factor XII mutations, and unknown origin) and four types of acquired angioedema (C1-INH deficiency, related to ACE inhibitors intake, idiopathic histaminergic, and idiopathic non-histaminergic) are presented. We will review the distinctive clinical features of each phenotype in details.

    Angioedema is defined as local, noninflammatory, self-limiting edema that is circumscribed owing to increased leakage of plasma from the capillaries located in the deep layers of the skin and the mucosae. Two mediators, histamine and bradykinin, account for most cases of angioedema. Angioedema can occur with wheals as a manifestation of urticaria, and this form is frequently allergic. In the present review, we discuss nonallergic angioedema without wheals, which can be divided into 3 acquired and 4 hereditary forms. Histamine is the mediator in acquired angioedema of unknown etiology (idiopathic histaminergic acquired angioedema), whereas in other forms the main mediator is bradykinin. Angioedema can be caused by C1-inhibitor deficiency (C1-INH-hereditary angioedema and C1-INH-acquired angioedema), mutations in coagulation factor XII (FXII-hereditary angioedema), and treatment with angiotensin-converting enzyme inhibitors (ACEI-acquired angioedema). Etiology remains unclear in acquired angioedema (idiopathic nonhistaminergic acquired angioedema) and in 1 type of hereditary angioedema (hereditary angioedema of unknown origin). Several treatments are licensed for hereditary C1-INH deficiency. Plasma-derived and recombinant C1-INHs, the bradykinin receptor blocker icatibant, and the plasma kallikrein inhibitor ecallantide have been approved for on-demand treatment to reverse angioedema symptoms. Attenuated androgen and plasma-derived C1-INH are approved for prophylaxis.

    Chronic idiopathic angioedema (CIA) is defined as three or more episodes of angioedema in a period of > 6 months without a clear etiology. In the study, we tried to explore clinical and laboratory characteristics of patients with CIA unaccompanied by urticaria. We retrospectively reviewed clinical and laboratory characteristics of 1238 patients with chronic urticaria and/or angioedema referred to our allergy clinic. Eight hundred and forty-one (67.9%) subjects had chronic urticaria without angioedema (CU Group), 323 (26.1%) had both urticaria and angioedema (CU + CA group), and 74 (5.9%) had chronic angioedema without urticaria (CA). In 29 (39.2%) cases of CA, no etiologic factor of angioedema was discovered, thus the patients were defined as having chronic idiopathic angioedema (CIA Group). Twenty-two (75.8%) subjects had antihistamine-responsive CIA and seven (24.1%) had antihistamine-unresponsive CIA. There were no statistically significant differences in clinical (except of urticarial eruptions) and laboratory characteristics between CU, CA + CU, and CIA groups. Antihistamine responsive and antihistamine-unresponsive CIA groups had no distinguishable clinical or laboratory features. We suppose that CIA, at least its antihistamine-responsive form, represents a rare form of chronic spontaneous urticaria. The reasons why in CIA there are no other clinical signs of mast cell/basophil activation, such as pruritus, urticarial, and dermatographism, are largely unknown and have to be elucidated in future studies. © 2014 The International Society of Dermatology.

    Idiopathic angioedema is defined as localized swelling of the cutaneous and mucosal tissue that occurs in episodes without a clear etiology. It can be problematic to treat when the underlying pathophysiology is not well understood. To identify successful treatments of idiopathic angioedema reported in the literature. A literature search was performed using PubMed. Published case reports and articles discussing treatment of idiopathic angioedema were used in the formulation of this review. In addition, 2 case reports are provided. Although there are no approved treatments for idiopathic angioedema, several medications used for the treatment of hereditary angioedema, such as bradykinin receptor antagonists (icatibant), kallikrein inhibitors (ecallantide), and C1 inhibitors, were successful in 10 patients. Anti-IgE monoclonal antibody (omalizumab) proved successful in 5 patients. The most widely used and successful medication was tranexamic acid (154 patients). Despite an unknown etiology, this article highlights viable treatment options for idiopathic angioedema. More clinical trials and better markers identifying the cause of angioedema are needed.

    Angioedema is swelling of the deep layers of the dermis and subcutaneous tissue due to an increase in vascular permeability. Angioedema sometimes occurs concomitantly with urticaria and represents an allergic disease. In other cases, angioedema is not associated with an allergic condition. We present the case of a 31-year-old woman with new-onset angioedema in the setting of her first pregnancy. After detailed history, physical examination, and laboratory evaluation, a cause for her angioedema was found that had not been considered previously and had significant implications for future management, particularly in light of her current pregnancy. Because allergists are commonly called on to evaluate and treat angioedema, we should be aware of the many disease processes that can present with this symptom and be well-versed in the workup of new-onset angioedema.

    Angioedema is a transient, localized swelling caused by two distinct mechanisms, mediated by histamine and bradykinin, respectively, although a proportion of cases remain idiopathic. Studies that characterize undifferentiated angioedema presenting in emergency departments (EDs) are limited. This study investigates the presentation patterns of undifferentiated angioedema in the ED based on the presumed mechanism of swelling. Medical records from all ED visits to two tertiary care hospitals from July 2007 to March 2012 were electronically reviewed. Records with documented visible swelling on general inspection and/or fiberoptic laryngoscopy and a diagnostic code for anaphylactic shock, angioneurotic edema, allergy unspecified, defects in the complement system, or unspecified drug adverse effects were included. Demographic, clinical, and outcome data were collected via a standardized form. Data were analyzed descriptively, including frequencies and percentages for categorical data and means and SDs for continuous data. Predictors for admission were identified using multivariate logistic regression models. ED records from 527 visits for angioedema by 455 patients were included in the study. Annual rate of angioedema was 1 per 1000 ED visits. Urticaria was associated with peripheral (p = 0.008) and lip angioedema (p = 0.001), and the absence of urticaria correlated with tongue angioedema (p = 0.001) and trended toward correlation with pharyngeal angioedema (p = 0.056). Significant predictors of admission included nonsteroidal anti-inflammatory drug-induced angioedema (odds ratio [OR], 15.3), epinephrine treatment (OR, 8.34), hypotension (OR, 15.7), multiple-site angioedema (OR, 4.25), and pharyngeal (OR, 1.23) and tongue angioedema (OR, 4.62). Concomitant urticaria was associated with a significant longer stay in the ED (p angioedema, need for airway management, length of ED visit, and recurrence.

    Hospital admission data indicate that the angioedema incidence has increased during the past several decades. Little is known about mortality trends. To count the number of deaths associated with angioedema in the United States, investigate correlations with age, sex, race, and other contributory causes, and analyze trends from 1979 to 2010. All US death certificates in which angioedema was listed as an underlying or contributing cause of death during 1979 to 2010 were analyzed. Age-adjusted mortality rates were analyzed by age, sex, and race. Other conditions designated as the underlying cause of death were investigated. From 1979 to 2010, there were 5,758 deaths in which angioedema was listed as a contributing cause. The age-adjusted death rate for hereditary angioedema decreased from 0.28 (95% confidence interval [CI] 0.25-0.32) to 0.06 (95% CI 0.05-0.08) per million persons per year. Conversely, mortality for angioedema increased from 0.24 (95% CI 0.21-0.27) to 0.34 (95% CI 0.31-0.37) per million. Blacks constituted 55% of angioedema deaths that were associated with use of angiotensin-converting enzyme inhibitors. On death certificates that listed hereditary angioedema as the underlying cause of death, cancer (frequently lymphoma or leukemia) was the second most commonly listed cause. Angioedema-associated deaths were very rare from 1979 to 2010. Hereditary angioedema deaths became even more so, whereas nonhereditary angioedema deaths increased. Risks associated with angiotensin-converting enzyme inhibitors were higher in blacks. Lack of specific coding for acquired angioedema most likely explains the observed association between cancer and hereditary angioedema. In the future, more granular coding systems may help distinguish hereditary from acquired angioedema. Copyright © 2014 American College of Allergy, Asthma & Immunology. Published by Elsevier Inc.

    Hereditary angioedema is an episodic swelling disorder with autosomal dominant inheritance characterized by sudden attacks of peripheral swelling. Patients also commonly have episodic swelling of the wall of hollow viscera, including the bowel. We present a 33-year-old previously healthy male with a complaint of acute-onset intense abdominal pain localized in the epigastrium. Pain irradiated to the right lower quadrant and was associated with five episodes of vomiting. Computed tomography showed thickening of the duodenal wall with liquid in the subphrenic space. Complementary laboratory tests showed low C4 complement levels (5.5 mg/dl) and 30% complement C1 inhibitor activity. Hereditary angioedema is caused by a deficiency (type I) or dysfunction (type II) in complement C1 inhibitor. Abdominal associated with angioedema may manifest as severe acute-onset abdominal pain or as moderately severe chronic recurrent abdominal pain. Two medications are currently FDA-approved for the treatment of these patients.

Herein, we report the case of a 23-year-old woman, with mild-moderate acne presenting with widespread facial angioedema on the 2nd day of systemic isotretinoin treatment. The patient had taken no drugs other than isotretinoin in the preceding days and had no known food allergy. Her angioedema was resolved after the isotretinoin was discontinued. We want to draw the attention of dermatologists to this rare adverse allergic effect of isotretinoin which is frequently used in the treatment of acne vulgaris.

    Angioedema, as a distinct disease entity, often becomes a clinical challenge for physicians, because it may cause a life-threatening condition, whereas prompt and accurate laboratory diagnostics may not be available. Although the bedside diagnosis needs to be established based on clinical symptoms and signs, family history, and the therapeutic response, later, laboratory tests are available. Currently, only for five out of the nine different types of angioedema can be diagnosed by laboratory testing, and these occur only in a minority of the patient population. Hereditary angioedema with C1-inhibitor (C1-INH) deficiency type I can be diagnosed by the low C1-INH function and concentration, whereas in type II, C1-INH function is low, but its concentration is normal or even elevated. C1q concentration is normal in both forms. Acquired angioedema with C1-INH deficiency type I is characterized by the low C1-INH function and concentration; however, C1q concentration is also low, and autoantibodies against C1-INH cannot be detected. Complement profile of acquired angioedema with C1-INH deficiency type II is similar to that of type I, but in this form, autoantibodies against C1-INH are present. Hereditary angioedema due to a mutation of the coagulation factor XII can be diagnosed exclusively by mutation analysis of FXII gene. Diagnostic metrics are not available for idiopathic histaminergic acquired angioedema, idiopathic non-histaminergic acquired angioedema, acquired angioedema related to angiotensin-converting enzyme inhibitor, and hereditary angioedema of unknown origin; these angioedemas can be diagnosed by medical and family history, clinical symptoms, and therapeutic response and by excluding the forms previously described. Several potential biomarkers of angioedema are used to date only in research. In the future, they could be utilized into the clinical practice to improve the differential diagnosis, therapy, as well as the prognosis of angioedema.

    2015-03-01

    Kinin-mediated angioedema results from accumulation of kinins, vasoactive and vasopermeant peptides, on the vascular endothelium. The disease is characterized by sudden episodes of swelling in the subcutaneous and submucosal tissues; the edema may occur spontaneously or it may be precipitated by triggering factors such as physical or emotional stress, or certain medicines. The characterization of kinin formation and catabolism systems helps improve knowledge of the aetiopathogenic mechanisms involved and provides the basis for classification of kinin-mediated angioedema conditions; thus, we may distinguish between angioedema with C1 inhibitor deficiency, whether inherited or acquired, and angioedema with normal C1 inhibitor activity, associated with increased kinin-forming activity or deficiency in kinin catabolism enzymes. In support of the clinical diagnosis, the physician may request laboratory investigation for a functional and molecular definition of the disease. Laboratory diagnosis is based on the characterization of: (1) kinin production control by C1 inhibitor investigation (function, antigen levels and circulating species); (2) kinin production (kininogenase activity, kininogen cleavage species); and (3) kinin catabolism enzymes (aminopeptidase P, carboxypeptidase N, angiotensin-I converting enzyme and dipeptidyl peptidase IV). An abnormal biological phenotype is supported by examination of susceptibility genes (SERPING1, F12 and XPNPEP2) and mutation segregation in the families. Copyright © 2015 Elsevier Masson SAS.

    In women with sporadic recurrent angioedema with an unknown cause who are unresponsive to antihistamines and have normal C1 inhibitor activity and a negative family history of angioedema, it is unclear whether they have idiopathic angioedema or hereditary angioedema with normal C1 inhibitor, and what impact exogenous estrogens have on their angioedema. A cohort of 147 women was analyzed for F12 exon 9 mutations and for the influence of oral contraceptives, hormonal replacement therapy, and pregnancy on their angioedema. A total of 142 women had idiopathic angioedema unresponsive to antihistamines. Five women had an F12 mutation and thereby hereditary angioedema with F12 mutations. Among the women with idiopathic angioedema, 63 had never taken estrogens. There was no estrogen impact in 42 women, a moderate impact in 15 women, and a severe impact in 22 women. The type and dose of estrogens did not differ in women with and without an estrogen impact. In 5 women, idiopathic angioedema disappeared after desogestrel use. Among the 5 women with hereditary angioedema with F12 mutations, angioedema symptoms occurred during 4 pregnancies, whereas no symptoms occurred during any of the 58 pregnancies in women with idiopathic angioedema. Women with recurrent angioedema unresponsive to antihistamines may have idiopathic angioedema or, more rarely, hereditary angioedema with F12 mutations. Both conditions may be provoked or aggravated by exogenous estrogens. In idiopathic angioedema, treatment with progestins may be helpful. Copyright © 2013. Published by Elsevier Inc.

    The use of fillers for cosmetic purposes is becoming increasingly frequent. Although initially considered inert, these products produce adverse reactions around the injection site. We present 5 cases of women with a history of filler injections who presented a hard and persistent angioedema followed by local subcutaneous nodules. They were referred to the allergist for suspected allergy related angioedema without response to usual antihistamine treatment. The angioedema episodes initiated 27.6 months (range 1 to 48) after the fillers treatment. The patients underwent exacerbations and remissions of angioedema, partially relieved with oral steroids and, in 2 cases, local triamcinolone injections. Mean time from onset of symptoms to remission of angioedema was 8.75 months (range 1 to 24). Until October 2009 four patients continued into remission after 24.5 months (range 7 to 36) free of symptoms. One patient continued with exacerbations 11 months after the initial symptoms. Fillers may cause angioedema as an adverse event and should be considered in the differential diagnosis of persistent angioedema. They are only sensitive to steroid treatment and in some steroid dependent cases they respond to ciclosporin. The frequency of angioedema after filler injections among patients with angioedema in the Unit of Asthma Allergy and Clinical Immunology was 0.5%.

    Angioedema is an episodic swelling of the deep dermis, subcutis, and/or submucosal tissue due to an increase in local vascular permeability. Swelling may involve skin, respiratory, and gastrointestinal tracts. The most commonly involved areas are the periorbital region and the lips. Here we report a case of a fatal laryngeal obstruction due to angioedema likely caused by an angiotensin-converting-enzyme inhibitor. The decedent, a 58-year-old man, was witnessed developing sudden facial swelling and acute respiratory difficulties quickly followed by unresponsiveness. His past medical history suggested that this was his second episode of angioedema without urticaria. Postmortem examination revealed a complete laryngeal obstruction in the absence of infection, neoplasm, or autoimmune disease. Postmortem computed tomography of the head and neck showed a complete obstruction of the upper airway. Based on the current understanding of the pathophysiology of different types of angioedema, we will suggest a workup of angioedema without urticaria in the forensic setting and offer readers resources they can use in their practice.

  3. Angioedema attacks in patients with hereditary angioedema: Local manifestations of a systemic activation process.

    Hereditary angioedema (HAE) caused by a deficiency of functional C1-inhibitor (C1INH) becomes clinically manifest as attacks of angioedema. C1INH is the main inhibitor of the contact system. Poor control of a local activation process of this system at the site of the attack is believed to lead to the formation of bradykinin (BK), which increases local vasopermeability and mediates angioedema on interaction with BK receptor 2 on the endothelium. However, several observations in patients with HAE are difficult to explain from a pathogenic model claiming a local activation process at the site of the angioedema attack. Therefore we postulate an alternative model for angioedema attacks in patients with HAE, which assumes a systemic, fluid-phase activation of the contact system to generate BK and its breakdown products. Interaction of these peptides with endothelial receptors that are locally expressed in the affected tissues rather than with receptors constitutively expressed by the endothelium throughout the whole body explains that such a systemic activation process results in local manifestations of an attack. In particular, BK receptor 1, which is induced on the endothelium by inflammatory stimuli, such as kinins and cytokines, meets the specifications of the involved receptor. The pathogenic model discussed here also provides an explanation for why angioedema can occur at multiple sites during an attack and why HAE attacks respond well to modest increases of circulating C1INH activity levels because inhibition of fluid-phase Factor XIIa and kallikrein requires lower C1INH levels than inhibition of activator-bound factors.

  9. Cardiovascular and Diabetic Medications That Cause Bradykinin-Mediated Angioedema.

    Science.gov (United States)

    Hudey, Stephanie N; Westermann-Clark, Emma; Lockey, Richard F

    Medication-induced angioedema is a bradykinin-mediated process that results from increased production or decreased degradation of bradykinin. These reactions are documented for several cardiac medications including blockers of the renin-angiotensin-aldosterone system (RAAS). Other cardiovascular and diabetes medications further increase the risk of medication-induced angioedema, particularly with concomitant use of RAAS inhibitors. Dipeptidyl peptidase IV inhibitors are a class of oral diabetic agents that affect bradykinin and substance P degradation and therefore can lead to angioedema. Neprilysin inhibitors are a separate class of cardiac medications, which includes sacubitril, and can lead to drug-induced angioedema especially when used in combination with RAAS inhibitors. This article discusses the proposed mechanisms by which these medications cause angioedema and how medication-induced angioedema differs from mast cell-mediated angioedema. It also details how to recognize medication-induced angioedema and the treatment options available. Copyright © 2017 American Academy of Allergy, Asthma & Immunology. Published by Elsevier Inc.

    It is rare for angioedema to be misidentified by the experienced clinician or for it to mimic another disease process. As an Emergency Physician, it is important to recognize and treat angioedema immediately. Of equal importance is the recognition and initiation of treatment of facial cellulitis. A case report follows that illustrates methicillin-resistant Staphylococcus aureus (MRSA) lip infection mimicking angioedema. Here, we describe a case of a 21-year-old man who presented with a swollen lower lip, initially diagnosed as angioedema. Further investigation revealed the cause of his lip swelling was actually a MRSA abscess and surrounding cellulitis, an unusual presentation for lip infection, which we discuss below. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Misidentifying MRSA lip infection for angioedema, with a delay in proper treatment, could result in serious morbidity or mortality.

    Acute angioedema represents a cause of admission to the emergency department requiring rapid diagnosis and appropriate management to prevent airway obstruction. Several drugs, including angiotensin-converting enzyme inhibitors (ACE-I), nonsteroidal anti-inflammatory drugs (NSAIDs) and oral antidiabetics, have been reported to induce angioedema. The aim of this prospective observational study conducted in a setting of routine emergency care was to evaluate the incidence and extent of drug-induced non-histaminergic angioedema in this specific clinical setting, and to identify the class of drugs possibly associated with angioedema. Patients admitted to seven different emergency departments (EDs) in Rome with the diagnosis of angioedema and urticaria were enrolled during a 6-month period. Of the 120,000 patients admitted at the EDs, 447 (0.37 %) were coded as having angioedema and 655 (0.5 %) as having urticaria. After accurate clinical review, 62 cases were defined as drug-induced, non-histaminergic angioedema. NSAIDs were the most frequent drugs (taken by 22 out of 62 patients) associated with the angioedema attack. Of the remaining patients, 15 received antibiotic treatment and 10 antihypertensive treatment. In addition, we observed in our series some cases of angioedema associated with drugs (such as antiasthmatics, antidiarrheal and antiepileptics) of which there are few descriptions in the literature. The present data, which add much needed information to the existing limited literature on drug-induced angioedema in the clinical emergency department setting, will provide more appropriate diagnosis and management of this potentially life-threatening adverse event.

    Full Text Available Hereditary angioedema is an autosomal dominant disease characterized by edema attacks with multiple organ involvement. It is caused by a quantitative or functional deficiency of the C1 inhibitor, which is a member of the serine protease inhibitor family. Hereditary angioedema is unknown to many health professionals and is therefore an underdiagnosed disease. The causes of death from hereditary angioedema include laryngeal edema with asphyxia. The estimated mortality rate in patients in whom the disease goes undetected and who are therefore incorrectly treated is 25-40%. In addition to edema of the glottis, hereditary angioedema often results in edema of the gastrointestinal tract, which can be incapacitating. Patients with hereditary angioedema may undergo unnecessary surgical interventions because the digestive tract can be the primary or only organ system involved, thus mimicking acute surgical abdomen. It is estimated that patients with hereditary angioedema experience some degree of disability 20-100 days per year. The Experts in Clinical Immunology and Allergy of the "Associação Brasileira de Alergia e Imunopatologia -ASBAI" developed these guidelines for the diagnosis, therapy, and management of hereditary angioedema.

    Angiotensin-converting enzyme inhibitors (ACE-I) are widely used, effective, and well-tolerated antihypertensive agents. The mechanisms by which those agents act can cause side effects such as decreased blood pressure, hyperkalemia, and impaired renal function. ACE-I can induce cough in 5%-35% and angioedema in up to 0.7% of treated patients. Because cough and angioedema are considered class adverse effects, switching treatment to other ACE-I agents is not recommended. Angioedema due to ACE-I has a low fatality rate, although deaths have been reported when the angioedema involves the airways. Here, we review the role of bradykinin in the development of angioedema in patients treated with ACE-I, as well as the incidence, risk factors, clinical presentation, and available treatments for ACE-I-induced angioedema. We also discuss the risk for recurrence of angioedema after switching from ACE-I to angiotensin receptor blockers treatment. Copyright © 2015 Elsevier Inc. All rights reserved.

    Angioedema refers to a localized, transient swelling of the deep skin layers or the upper respiratory or gastrointestinal mucosa. It develops as a result of mainly two different vasoactive peptides, histamine or bradykinin. Pathophysiology, as well as treatment, is different in each case; nevertheless, the resulting signs and symptoms may be similar and difficult to distinguish. Angioedema may occur at any location. When the affected area involves the upper respiratory tract, both forms of angioedema can lead to an imminent upper airway obstruction and a life-threatening emergency. Emergency physicians must have a basic understanding of the pathophysiology underlying this process. Angioedema evaluation in the emergency department (ED) should aim to distinguish between histamine- and bradykinin-induced angioedema, in order to provide appropriate treatment to patients. However, diagnostic methods are not available at the ED setting, neither to confirm one mechanism or the other, nor to identify a cause. For this reason, the management of angioedema should rely on clinical data depending on the particular features of the episode and the patient in each case. The history-taking should be addressed to identify a possible etiology or triggering agent, recording complete information for an ulterior diagnostic study in the outpatient clinic. It is mandatory quickly to recognize and treat a potential life-threatening upper airway obstruction or anaphylaxis. This review focuses on the underlying mechanisms and management of histamine- and bradykinin-induced angioedema at the emergency department and provides an update on the currently available treatments.

  18. Emerging concepts in the diagnosis and treatment of patients with undifferentiated angioedema

    Science.gov (United States)

    2012-01-01

    Angioedema is a sudden, transient swelling of well-demarcated areas of the dermis, subcutaneous tissue, mucosa, and submucosal tissues that can occur with or without urticaria. Up to 25% of people in the US will experience an episode of urticaria or angioedema during their lifetime, and many will present to the emergency department with an acute attack. Most cases of angioedema are attributable to the vasoactive mediators histamine and bradykinin. Histamine-mediated (allergic) angioedema occurs through a type I hypersensitivity reaction, whereas bradykinin-mediated (non-allergic) angioedema is iatrogenic or hereditary in origin. Although their clinical presentations bear similarities, the treatment algorithm for histamine-mediated angioedema differs significantly from that for bradykinin-mediated angioedema. Corticosteroids, and epinephrine are effective in the management of histamine-mediated angioedema but are ineffective in the management of bradykinin-mediated angioedema. Recent advancements in the understanding of angioedema have yielded pharmacologic treatment options for hereditary angioedema, a rare hereditary form of bradykinin-mediated angioedema. These novel therapies include a kallikrein inhibitor (ecallantide) and a bradykinin β2 receptor antagonist (icatibant). The physician’s ability to distinguish between these types of angioedema is critical in optimizing outcomes in the acute care setting with appropriate treatment. This article reviews the pathophysiologic mechanisms, clinical presentations, and diagnostic laboratory evaluation of angioedema, along with acute management strategies for attacks. PMID:23131076

    Angioedema (AE) is characterized by nonpitting edema of the dermis and subcutaneous layers. The most common sites of involvement are the tongue, lips, face, and throat; however, swelling can also occur in the extremities, genitalia, and viscera. Life-threatening airway swelling can also occur. AE may be allergic or nonallergic. The overall lifetime incidence of AE is reported to be as high as 15%. This article summarizes the etiology, pathophysiology, and current treatment of several forms of nonallergic AE (including hereditary, acquired, and idiopathic AE) and focuses on angiotensin-converting enzyme inhibitor-induced angioedema (ACEi-AE), which is responsible for 30%-40% of all AE seen in United States emergency departments. Although the triggers, which are primary biologic mechanisms, and treatments for ACEi-AE may differ from those of the hereditary and acquired forms of AE, the clinical effects of ACEi-AE are mediated through a shared pathway, the kallikrein-kinin system. Thus, although current therapeutic options for ACEi-AE are limited, recent advances in the treatment of hereditary AE (HAE) appear promising for improving the outcomes of patients with ACEi-AE. New HAE medications that correct imbalances in the kallikrein-kinin system may prove safe and efficacious in the treatment of ACEi-AE. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Angioedema secondary to C1 inhibitor deficiency has been rarely reported to be associated with systemic lupus erythematosus. A genetic defect of C1 inhibitor produces hereditary angioedema, which is usually presented with cutaneous painless edema, but edema of the genital area, gastrointestinal and laryngeal tracts have also been reported. In lupus patients, angioedema may be the result of an acquired type of C1 inhibitor deficiency, most probably due to antibody formation directed against the C1 inhibitor molecule. Herein we report a new case of lupus nephritis that developed angioedema and a rapid course of disease progression with acute renal failure and alveolar hemorrhage without response to high dose steroid and plasmapheresis.

    Full Text Available Angioedema can cause potentially life-threatening airway obstruction. This case report describes an exceedingly rare episode of ticagrelor-induced hypersensitivity reaction, manifesting as angioedema with periorbital and likely respiratory involvement. The heart team should be vigilant for this precarious condition which may require emergent airway management. Desensitization protocols and alternative regimens (e.g., clopidogrel, prasugrel, and addition of an adjunctive anticoagulant should be considered when there is an absolute indication for antiplatelet therapy.

    Two types of bradykinin-mediated angioedema, hereditary angioedema (HAE) and acquired angioedema (AAE), result from deficiency or dysfunction of C1 esterase inhibitor, leading to an overproduction of bradykinin, which can lead to vascular permeability and life-threatening angioedema of the airway. The objective of this study was to review perioperative outcomes in a series of patients with HAE and AAE and to review current knowledge about anesthetic complications in patients with HAE or AAE. Medical records were retrospectively reviewed for perioperative complications in patients with HAE or AAE who underwent general anesthesia from January 1, 2000, to December 31, 2014, at our institution. Twenty-four patients (13 with HAE, 10 with AAE, and 1 with unspecified angioedema) underwent 38 instances of general anesthesia with airway manipulation. All except 4 received prophylactic therapy. One patient, a 67-year-old woman who was pretreated with stanozolol and fresh frozen plasma required reintubation after postoperative airway edema developed. Life-threatening episodes of angioedema of the airway occur infrequently, but they can occur in patients who received pretreatment and in patients who have previously undergone anesthesia uneventfully. Anesthesiologists must be ready to emergently manage a difficult airway and must be familiar with recommendations provided in consensus guidelines for the treatment of HAE and AAE patients.

    Angiotensin-converting-enzyme inhibitors (ACEI) are one of the most prescribed medications worldwide. Angioedema is a well-recognized adverse effect of this class of medications, with a reported incidence of ACEI angioedema of up to 1.0%. Of importance to note, ACEI angioedema is a class effect and is not dose dependent. The primary goal of this literature search was to determine the appropriate Emergency Department management of patients with ACEI angioedema. A MEDLINE literature search from January 1990 to August 2012 and limited to human studies written in English for articles with keywords of ACEI angioedema. Guideline statements and non-systematic reviews were excluded. Studies identified then underwent a structured review from which results could be evaluated. Five hundred sixty-two papers on ACEI angioedema were screened and 27 appropriate articles were rigorously reviewed in detail and recommendations given. The literature search did not support any specific treatment protocol with a high level of evidence due to the limited--and limitations of the--available studies. Copyright © 2013 Elsevier Inc.

    Present the clinical signs of bradykinin-mediated angioedema, a disease little known to intensive care anaesthesiologists, and develop their scientific basis with recent data on management in emergency and perioperative care. International recommendations and recent general reviews. Data collection was performed using the Medline database with the keyword: angioedema. Research studies published during the last 10 years were reviewed. Relevant clinical information was extracted and discussed. Angioedema is a clinical syndrome characterized by episodes of transitory recurrent submucosal and subcutaneous oedema, called attacks. During an attack, the oedema may be localized at the level of the skin and/or ENT and digestive tract mucosa. This syndrome is not due to an allergic reaction. It is related to a C1 complement inhibitor deficiency or an increase in factor XII resulting in the excessive release of bradykinin, which leads to capillary permeability. There are hereditary and acquired forms, notably associated with the use of ACE inhibitors and sartans. This rare disease should be recognized by anaesthesiologists and intensive care and emergency physicians because, in the absence of specific treatment, it can be life-threatening due to the appearance of laryngeal oedema. In addition, there is a risk that the patient may have an attack during the perioperatory period, due to surgical trauma. International recommendations exist, and there are new molecules available in France. For moderate attacks, treatment is based on tranexamic acid. For hereditary forms, according to the localization and gravity of the attacks, emergency treatment is based on the use of Icatibant, a bradykinin B2 receptor inhibitor, and C1 inhibitor concentrate. For pregnant women and acquired forms, C1 inhibitor concentrate is the treatment of reference. Antalgic and perfusion treatments should not be neglected, and should be modified as a function of clinical signs. High-risk situations

    Approximately 50% of patients with chronic idiopathic/spontaneous urticaria (CIU/CSU) report hives and angioedema; some experience hives/angioedema only. Assess omalizumab's effect on angioedema and quality of life (QoL) in subgroups with refractory CIU/CSU: those with and without angioedema. Patients received omalizumab (75, 150 or 300 mg) or placebo every 4 weeks for 12/24 weeks. Angioedema and QoL were assessed [Urticaria Patient Daily Diary and Dermatology Quality of Life Index (DLQI)]. Subgroups were based on the presence/absence of baseline angioedema 7 days prior to randomization. Patients with baseline angioedema randomized to omalizumab 300 mg had a greater reduction in mean weekly incidence of angioedema and mean number of days/week with angioedema vs. placebo at 12 and 24 weeks. A 3.3- to 4.5-point greater mean reduction in DLQI score was achieved with omalizumab 300 mg treatment vs. placebo, above the minimal clinically important difference threshold. Results with lower doses vs. placebo were variable. Compared with placebo, omalizumab 300 mg treatment over 12-24 weeks resulted in marked reduction in incidence and number of days/week with angioedema accompanied by clinically relevant improvement in QoL. © 2016 European Academy of Dermatology and Venereology.

    We describe the diagnostic epidemiology, the clinical course, the family history and the response to treatment of patients with angioedema without wheals (AWW) at an Allergy and Immunology Clinical Center. We reviewed the case records of all patients at our office from January 1997 to April 2013. We recorded sex, age, age at onset of symptoms, family history of angioedema, number of visits to the office, type of angioedema, and response to treatment from those patients with angioedema without wheals. We classified angioedema according to its pathophysiology. We also describe those patients with angioedema mimics. From a total of 17,823 new patients, 303 had a presumptive diagnosis of angioedema without wheals. Twenty-three patients had an angioedema mimic. Forty percent were male and 60% were female. Average age at first visit was 40.6. Average number of visits was 2.4. Fifty-seven patients referred a family history. We attributed idiopathic angioedema to 55.7% of patients, 24.3% were drug related, 15.7% were due to C1 inhibitor deficiency, 2.1% were drug related+idiopathic angioedema, 1.4% were type III and 0.7% had exercise-induced angioedema. Ninety six percent of 53 evaluable idiopathic angioedema patients referred a benefit with anti-histamine therapy. AWW was a rare cause of consultation. Most of our patients had anti H1 responsive idiopathic angioedema and none had allergic angioedema. Women cases prevailed over men's. Family history and average age of onset of symptoms were different among the different types of angioedema.

  15. New treatments addressing the pathophysiology of hereditary angioedema

    Directory of Open Access Journals (Sweden)

    2008-04-01

    Full Text Available Abstract Hereditary angioedema is a serious medical condition caused by a deficiency of C1-inhibitor. The condition is the result of a defect in the gene controlling the synthesis of C1-inhibitor, which regulates the activity of a number of plasma cascade systems. Although the prevalence of hereditary angioedema is low – between 1:10,000 to 1:50,000 – the condition can result in considerable pain, debilitation, reduced quality of life, and even death in those afflicted. Hereditary angioedema presents clinically as cutaneous swelling of the extremities, face, genitals, and trunk, or painful swelling of the gastrointestinal mucosa. Angioedema of the upper airways is extremely serious and has resulted in death by asphyxiation. Subnormal levels of C1-inhibitor are associated with the inappropriate activation of a number of pathways – including, in particular, the complement and contact systems, and to some extent, the fibrinolysis and coagulation systems. Current findings indicate bradykinin, a product of contact system activation, as the primary mediator of angioedema in patients with C1-inhibitor deficiency. However, other systems may play a role in bradykinin's rapid and excessive generation by depleting available levels of C1-inhibitor. There are currently no effective therapies in the United States to treat acute attacks of hereditary angioedema, and currently available agents used to treat hereditary angioedema prophylactically are suboptimal. Five new agents are, however, in Phase III development. Three of these agents replace C1-inhibitor, directly addressing the underlying cause of hereditary angioedema and re-establishing regulatory control of all pathways and proteases involved in its pathogenesis. These agents include a nano-filtered C1-inhibitor replacement therapy, a pasteurized C1-inhibitor, and a recombinant C1-inhibitor isolated from the milk of transgenic rabbits. All C1-inhibitors are being investigated for acute angioedema

    During the last years, two new cardiovascular drug classes, namely inhibitors of DPP IV or neprilysin, have been developed. In both cases, there is clinical evidence for their potential to induce angioedema as known already from blockers of the renin-angiotensin-aldosterone system (RAAS). The majority of angioedema induced by DPP IV inhibitors occurs during concomitant treatment with ACEi and is therefore likely mediated by overactivation of bradykinin type 2 receptors (B2). In striking contrast, the molecular pathways causing angioedema induced by neprilysin inhibitors, that is, sacubitril, are unclear, although a contribution of bradykinin appears likely. Nevertheless, there is no clinical evidence suggesting that inhibition of B2 might relieve the symptoms and/or prevent invasive treatment including coniotomy or tracheotomy in angioedema caused by these drugs. Therefore, the risk of angioedema should always be considered, especially in ambulatory care situations where patients have no rapid access to intensive care. © 2015 John Wiley & Sons A/S.

    Angiotensin-converting enzyme (ACE) inhibitors are a commonly used class of medications that are generally well tolerated. However, angioedema, a rare but potentially life-threatening adverse effect, may occur. A retrospective audit was performed on patients who presented with angioedema to two emergency departments in Adelaide, Australia. Case notes of patients presenting with angioedema who were using an ACE inhibitor were reviewed. This study examined the clinical features of presentation, treatment and outcomes of the patients. A total of 164 patients were identified as having angioedema across the two emergency departments. Fifty-one (31%; 95% CI = 24-39) were found to be on an ACE inhibitor. The two main presenting symptoms were soft tissue swelling in the head and neck (98%), and respiratory distress (33%), both of which usually developed after several hours. Patients were commonly treated with steroids (70%), antihistamines (65%) and adrenaline (35%). Two patients developed airway obstruction. A substantial proportion of emergency department encounters with angioedema in South Australia are from patients who also use an ACE inhibitor. It is important that general practitioners are aware of this problem, to enable rapid recognition and appropriate patient education when prescribing these medications.

    Angiotensin-converting enzyme inhibitors (ACEIs) are a common cause of drug-induced angioedema in the United States. Most epidemiologic ACEI angioedema data are from large multicenter clinical trials. The objective of this study was to identify the incidence of and risk factors for ACEI angioedema using a large integrated electronic health record (EHR). We conducted a retrospective cohort study of all ACEI prescriptions in the outpatient setting of a large academic center between January 1, 2000, and September 30, 2008. We determined frequency, timing, and risk factors for ACEI angioedema within 5 years of prescription. All data were derived from EHR sources, with angioedema defined by EHR reactions of angioedema, swelling, edema, or lip, eye, face, tongue, throat or mouth swelling. Among 134,945 patients prescribed an ACEI, 0.7% (n = 888) developed angioedema during the subsequent 5 years. Sex was similar but patients who developed ACEI angioedema were younger (61.5 vs 62.7 years, P = .007). Patients with ACEI angioedema were more likely to have a history of nonsteroidal anti-inflammatory drug allergy compared with patients who did not develop angioedema (7.1% vs 4.2%, P angioedema within 1 month of prescription and a 0.23% incidence during the first year. Incidence of angioedema was relatively constant annually over the subsequent 4 years (0.10% to 0.12%). The incidence of ACEI angioedema within a large EHR is consistent with large clinical trial data. We observed a persistent and relatively constant annual risk; however, angioedema risk factors and underlying genetic and pathophysiological mechanisms require further study.

    Full Text Available Hereditary angioedema is a rare autosomal dominant disorder caused by reduced activity of the C1 esterase inhibitor. Patients with hereditary angioedema are clinically characterized by recurrent episodes of swelling of the extremities, face, trunk, airways and abdominal organs. Attacks may occur either spontaneously or following trauma, stress, surgery, infections and hormonal fluctuations. The most common cause of death is asphyxia related to laryngeal edema. Giving C1 esterase inhibitor is the most effective method of treatment. Also fresh frozen plasma, androgen steroids, quinine pathway inhibitors, antifibrinolytics and bradykinin receptor antagonists can be used as treatment. In this paper, the anesthetic management of a patient with hereditary angioedema undergoing inguinal hernia repair surgery is reported.

    Full Text Available Hereditary angioedema (HAE caused by a deficiency of C1 esterase inhibitor enzyme (C1-INH is a very rare, autosomal dominantly inherited genetic disorder, characterized by recurrent peripheral angioedema, painful abdominal attacks and episodes of laryngeal edema. Abdominal attacks are frequent symptoms in adult HAE patients, occurring in more than 90% of the cases. Angioedema in the bowel or abdomen can occur in the absence of cutaneous manifestations and may be easily misdiagnosed unless the clinician has a high degree of awareness to include HAE in the differential diagnosis. Misdiagnosis is associated with inadequate treatments, including unnecessary surgical procedures. Any patient who presents recurrent episodes of swelling should be evaluated for HAE caused by C1-INH deficiency. New therapies could save lives and dramatically improve their quality of life.

    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. Early recognition of this rare clinical condition and taking precautions for providing airway patency are essential. In this case report, we will discuss mimicking angioedema and caused by a bite due to dystonia and separation of the tongue from the base of the mouth developing concurrently with lingual hematoma.

    2008-06-01

    Hyaluronic acid injections are becoming popular in aesthetic dermatology, and, sometimes, misplacements and very rarely adverse events have been reported. Hyaluronidase, an enzyme that hydrolyzes hyaluronic acid, is used to treat overcorrection or granulomatous reactions. Allergic reactions are well known except for how frequent they occur. This paper aims to confirm the efficacy of hyaluronidase injections to dissolve hyaluronic acid, but insists on the risk of hypersensitivity with animal-derived products. A case of angioedema due to ovine hyaluronidase is reported, and treatment is discussed. Hyaluronidase is highly effective, but skin test must be done before injection to avoid risk of angioedema and/or Quincke's edema.

    Icatibant is used to treat acute hereditary angioedema with C1 inhibitor deficiency types I/II (C1-INH-HAE types I/II) and has shown promise in angioedema due to acquired C1 inhibitor deficiency (C1-INH-AAE). Data from the Icatibant Outcome Survey (IOS) were analysed to evaluate the effectiveness of icatibant in the treatment of patients with C1-INH-AAE and compare disease characteristics with those with C1-INH-HAE types I/II. Key medical history (including prior occurrence of attacks) was recorded upon IOS enrolment. Thereafter, data were recorded retrospectively at approximately 6-month intervals during patient follow-up visits. In the icatibant-treated population, 16 patients with C1-INH-AAE had 287 attacks and 415 patients with C1-INH-HAE types I/II had 2245 attacks. Patients with C1-INH-AAE versus C1-INH-HAE types I/II were more often male (69 versus 42%; P = 0·035) and had a significantly later mean (95% confidence interval) age of symptom onset [57·9 (51·33-64·53) versus 14·0 (12·70-15·26) years]. Time from symptom onset to diagnosis was significantly shorter in patients with C1-INH-AAE versus C1-INH-HAE types I/II (mean 12·3 months versus 118·1 months; P = 0·006). Patients with C1-INH-AAE showed a trend for higher occurrence of attacks involving the face (35 versus 21% of attacks; P = 0·064). Overall, angioedema attacks were more severe in patients with C1-INH-HAE types I/II versus C1-INH-AAE (61 versus 40% of attacks were classified as severe to very severe; P < 0·001). Median total attack duration was 5·0 h and 9·0 h for patients with C1-INH-AAE versus C1-INH-HAE types I/II, respectively. © 2016 British Society for Immunology.

    The term "swelling" has been used in the old scriptures to illustrate a change of normal figure and, as such, an expression of illness. It should be noted that in ancient times, human diseases were very often regarded a punishment from God. Hence, it is not surprising that one of the oldest tests for infidelity involved swelling as an inflicted punishment. The great Greek physician Hippocrates (377-460 BC), considered one of the most outstanding figures in the history of medicine and "Father of the Western Medicine," already used the term oídēma to describe swelling of organs. It took many centuries later until the first description of angioedema as a distinct medical entity was minted by Quinke in 1882. The historical progression in angioedema research has been characterized by intermittent "leaps" in interest and scientific achievements. As an example, it took 75 years from the accurate description of hereditary angioedema (HAE) by Osler (1888), until a group of researchers headed by Donaldson (1963) disclosed the central role of C1 inhibitor in angioedema pathophysiology. What followed was a result of a collective effort by many researchers and scientific groups who were able to elucidate the intricate connections between the implicated biochemical pathways. Still, scientific progress was hardly translated into effective therapy, and another 45 years had to elapse until the renewed interest in HAE was boosted by studies on the efficacy and safety of novel therapies about 10 years ago. In the twenty-first century, HAE ceased to be an "orphan disease" and its future is far more optimistic. It is better managed now by specialized angioedema centers, harmonized clinical guidelines, educational programs, laboratory services, and continued basic and clinical research. Patient associations worldwide are offering support and guidance, and governments and healthcare systems are gradually addressing patient and family needs.

    Hereditary angioedema is characterized by recurrent attacks of angioedema of the skin, larynx, and gastrointestinal tract. Bradykinin is the key mediator of symptoms. Icatibant is a selective bradykinin B2 receptor antagonist. In two double-blind, randomized, multicenter trials, we evaluated the effect of icatibant in patients with hereditary angioedema presenting with cutaneous or abdominal attacks. In the For Angioedema Subcutaneous Treatment (FAST) 1 trial, patients received either icatibant or placebo; in FAST-2, patients received either icatibant or oral tranexamic acid, at a dose of 3 g daily for 2 days. Icatibant was given once, subcutaneously, at a dose of 30 mg. The primary end point was the median time to clinically significant relief of symptoms. A total of 56 and 74 patients underwent randomization in the FAST-1 and FAST-2 trials, respectively. The primary end point was reached in 2.5 hours with icatibant versus 4.6 hours with placebo in the FAST-1 trial (P=0.14) and in 2.0 hours with icatibant versus 12.0 hours with tranexamic acid in the FAST-2 trial (P<0.001). In the FAST-1 study, 3 recipients of icatibant and 13 recipients of placebo needed treatment with rescue medication. The median time to first improvement of symptoms, as assessed by patients and by investigators, was significantly shorter with icatibant in both trials. No icatibant-related serious adverse events were reported. In patients with hereditary angioedema having acute attacks, we found a significant benefit of icatibant as compared with tranexamic acid in one trial and a nonsignificant benefit of icatibant as compared with placebo in the other trial with regard to the primary end point. The early use of rescue medication may have obscured the benefit of icatibant in the placebo trial. (Funded by Jerini; ClinicalTrials.gov numbers, NCT00097695 and NCT00500656.)

    The incidence of bradykinin-induced angioedema is considerably lower than that of histamine-induced forms; however, the same is true for the clinician's knowledge of this condition. Bradykinin-induced angioedemas include hereditary angioedema (HAE), as well as acquired forms induced by drugs or antibody formation, e.g., during the course of oncologic disease. Drug-induced forms affect almost exclusively the head and neck region, and are thus important for the otorhinolaryngologist. Clear differentiation between histamine-induced angioedema (e. g., connected to allergy/urticaria) and bradykinin-induced angioedema is essential for selection of the specific treatment and may be lifesaving. Antihistamines and cortisone derivatives have no relevant effect in bradykinin induced-angioedema, whereas blood-derived C1 esterase inhibitor and bradykinin receptor 2 antagonists represent effective therapeutic options--both for acute and prophylactic treatment.

    To evaluate the etiology and risk factors for severe manifestation and recurrent episodes of angioedema; to evaluate efficacy of short-term and long-term management strategies for angioedema among a high-risk population. Institutional review board-approved retrospective review of a large, urban population. Data from 875 adult patients treated from January 2008 to December 2013 with the diagnosis of angioedema were obtained using the Clinical Looking Glass utility and review of medical records. Demographic and clinicopathologic risk factors were recorded. The major outcomes evaluated were hospital admission, need for airway intervention, and recurrent episodes of angioedema following the first presentation. Initial treatment strategy and follow-up recommendations were also recorded. The most common cause of angioedema was angiotensin converting enzyme inhibitor (ACEi)-induced (496 [56.6%]). Significant risk factors for severe cases of angioedema included older age, Hispanic race, ACEi-induced angioedema type, American Society of Anesthesiologists class III or above, coexistent cardiopulmonary disease, and a positive smoking history. A total of 17.2% of patients experienced recurrent attacks of angioedema; of those patients, 25.9% were still taking an ACEi at subsequent presentation. Risk factors for recurrent episodes included older age, idiopathic angioedema type, and coexistent cardiopulmonary disease. Only 54.1% of patients who experienced ACEi-induced angioedema had electronic medical record documentation of these allergies. Knowledge of risk factors for severe and recurrent episodes of angioedema and improved education for both healthcare providers and patients, specifically related to ACEi use and allergy documentation, may significantly decrease the burden and morbidity of angioedema among high risk populations. 2b. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

    The purpose of this study was to review consecutive cases of angiotensin-converting enzyme (ACE) inhibitor angioedema admitted to an intensive care unit. Fifty subjects with ACE-inhibitor angioedema admitted from 1998-2011 were reviewed. All 50 subjects were men, 62.8 ± 8.4 years of age, 76% African Americans. Fifteen (30%) required ventilatory support and 2 (4%) required tracheostomy. Over half (56%) had taken ACE inhibitors for over a year. Logistic regression identified dyspnea and tongue involvement with the need for ventilatory support (P angioedema. Angioedema can occur even after extended use. Dyspnea and tongue involvement identified patients requiring ventilatory support. Published by Elsevier Inc.

    Nonsteroidal antiinflammatory agents, β-lactam antibiotics, non-β lactam antibiotics, and angiotensin-converting enzyme inhibitors are the most common classes of drugs that cause angioedema. Drug-induced angioedema is known to occur via mechanisms mediated by histamine, bradykinin, or leukotriene, and an understanding of these mechanisms is crucial in guiding therapeutic decisions. Nonallergic angioedema occurs in patients with genetic variants that affect metabolism or synthesis of bradykinin, substance P, prostaglandins, or leukotrienes, or when patients are taking drugs that have synergistic mechanisms. The mainstay in treatment of nonallergic drug-induced angioedema is cessation of the offending agents. Copyright © 2017 Elsevier Inc. All rights reserved.

    C1-esterase inhibitor deficiency results in episodes of non-allergic edema of parts of the body. Edema of the face may be triggered by dental therapy. We report a case of C1-esterase inhibitor deficiency which was detected in a 42-year-old woman. The patient was completely unaware that she had this disorder or of any related family history, and the patient developed an intense facial angioedema after pulp extirpation of lower premolar tooth. In this case, the diagnosis of angioedema due to C1-esterase inhibitor deficiency was established at a later stage. The differing causes of C1-esterase inhibitor deficiency are briefly discussed and the treatment modalities outlined.

This articled has been intended to describe basic concepts for the understanding of Occupational Therapy intervention with acquired brain damage survivors.Current theories about motor control, cognition and learning have had an effect on recent therapeutic strategies used to improve functional performance after brain injury. It is generally accepted that human performance (daily life activities requires complex interactions between perceptual, cognitive, and motor systems in relation to specific tasks and environments. The ultimate goal of Occupational Therapy is to enable individuals to perform the tasks that are essential in their lives. An occupational therapist assess underlying motor, cognitive, perceptual, and interpersonal skills as well as task performance and valued roles. Depending on a person’s current potential for recovery, the occupational therapist facilitates task performance by improving relevant skills, developing and teaching compensatory strategies to overcome lost performance skills and maintain their own independence.RESUMEN:La Terapia Ocupacional constituye el uso propositivo de la actividad o intervenciones diseñadas para lograr objetivos funcionales que promuevan la salud, prevengan la enfermedad y que desarrollen la mejora, mantenimiento o recuperación del más alto nivel de independencia posible para cualquier sujeto que haya sufrido una lesión, enfermedad u otras dificultades.

    The association between thyroid autoimmunity (TA) and idiopathic isolated angioedema (or angioedema without urticaria) has not been evaluated in either children or in adults up until now. We, therefore, aimed to investigate underlying or concomitant TA and/or autoimmune thyroid disease in children diagnosed with recurrent idiopathic angioedema. Children who were consecutively diagnosed with recurrent idiopathic histaminergic acquired angioedema (IH-AAE) between January 2011 and January 2014 constituted the case group. A standard diagnostic and therapeutic algorithm was applied to all the patients with recurrent IH-AAE. Thyroid autoantibodies and thyroid function tests were measured in all the patients with recurrent IH-AAE and in healthy control groups. Prophylaxis with an antihistamine was started for patients with frequently recurrent IH-AAE. Eighty consecutive children with recurrent IH-AAE (49 boys; median age, 8.3 years) and 80 healthy children (39 boys; median, 8 years) were enrolled in this prospective, case-control study (p > 0.05 for age and sex). The IH-AAE group was significantly different than the control group with respect to TA (13.7% versus 2.5%, respectively; p = 0.009) but was similar with respect to autoimmune thyroid disease (3.7% versus 0%, respectively; p = 0.2). The median follow-up of the recurrent IH-AAE group was 34 months (range, 12-45 months). Patients with recurrent IH-AAE with and those without TA were not different with respect to either the need or the duration of antihistamine prophylaxis (p > 0.05 for both). Recurrent IH-AAE may be related to or associated with TA and/or autoimmune thyroid diseases in some children. However, exploring to see whether this association is a causal link or just an epiphenomenon deserves further investigation and longer follow-ups.

    Two male patients with hypogonadism and four female patients who received an anti-androgen as contraceptive (cyproteronacetate) and who had recurrent angioedema are described. In one male patient, augmentation of the plasma androgen level resulted in disappearance of symptoms. In the four female patients, recurrent angioedema and urticaria developed after initiation of the anti-androgen treatment. Cessation of cyproteronacetate and a change to another contraceptive resulted in complete resolution of the previously frequent angioedematous attacks. The women are still symptom free after more than 60 patient's months. These cases suggest that an androgen deficit due to either hypogonadism or to anti-androgen treatment may be another cause of angioedema. One of the two male patients was untreated and presented with 40% normal value of C1-INH. Androgen therapy normalized C1-INH concentration in this male patient. Functional C1-INH in the same patient, studied before and after the beginning of androgen therapy, clearly increased when assessed by inhibition of amidolytic activity of C1-esterase. The other male patient with hypogonadism had already been under androgen treatment for 4 years and had C1-INH levels in the normal range. In the female patients, complement profiles were normal before and after cessation of anti-androgen contraception; however, the C1-INH plasma levels were higher after cessation of anti-androgen anticonception. These results indicate an effect of androgen deficit on the level of C1-INH in circulating plasma but do not prove a role of C1-INH in angioedema associated with diminished androgen plasma levels.

    Full Text Available Abstract Hereditary angioedema (HAE resulting from the deficiency of the C1 inhibitor (C1-INH is a rare, life-threatening disorder. It is characterized by attacks of angioedema involving the skin and/or the mucosa of the upper airways, as well as the intestinal mucosa. In approximately 50 per cent of cases, clinical manifestations may appear during childhood. The complex management of HAE in pediatric patients is in many respects different from the management of adults. Establishing the diagnosis early, preferably before the onset of clinical symptoms, is essential in cases with a positive family history. Complement studies usually afford accurate diagnosis, whereas molecular genetics tests may prove helpful in uncertain cases. Appropriate therapy, supported by counselling, suitable modification of lifestyle, and avoidance of triggering factors (which primarily include mechanical trauma, mental stress and airway infections in children may spare the patient unnecessary surgery and may prevent mortality. Prompt control of edematous attacks, short-term prophylaxis and intermittent therapy are recommended as the primary means for the management of pediatric cases. Medicinal products currently used for the treatment of children with hereditary angioedema include antifibrinolytics, attenuated androgens, and C1-INH replacement therapy. Current guidelines favour antifibrinolytics for long-term prophylaxis because of their favorable safety profile but efficacy may be lacking. Attenuated androgens administered in the lowest effective dose are another option. C1-INH replacement therapy is also an effective and safe agent for children. Regular monitoring and follow-up of patients are necessary.

    Urticaria is a heterogeneous group of disorders, with various clinical manifestations and intensity of symptoms. Urticaria can be induced with a wide variety of environmental stimuli, such as cold, pressure, vibration, sunlight, exercise, temperature changes, heat, and water. In a select group of patients, exercise can induce a spectrum of urticaria symptoms, ranging from cutaneous pruritus and warmth, generalised urticaria, angioedema, and the appearance of such additional manifestations as collapse, upper respiratory distress, and anaphylaxis. Specific provocation tests should be carried out on an individual basis to investigate the suspected cause and proper diagnosis. Modification of activities and behaviour is the mainstay of treatment in patients with physical urticaria. The aim of this study was to emphasise that primary care paediatricians should be able to recognise physical urticaria, supply a patient with rescue medications, and refer him/her to a specialist. In the article, the authors present a 13-year-old girl with typical urticaria lesions and angioedema after exercise. According to the history, physical examination, and provocation test, exercise-induced urticaria and angioedema were diagnosed.

    Urticaria and angioedema are common clinical conditions representing a major concern for physicians and patients alike. The World Allergy Organization (WAO), recognizing the importance of these diseases, has contributed to previous guidelines for the diagnosis and management of urticaria. The Scientific and Clinical Issues Council of WAO proposed the development of this global Position Paper to further enhance the clinical management of these disorders through the participation of renowned experts from all WAO regions of the world. Sections on definition and classification, prevalence, etiology and pathogenesis, diagnosis, treatment, and prognosis are based on the best scientific evidence presently available. Additional sections devoted to urticaria and angioedema in children and pregnant women, quality of life and patient-reported outcomes, and physical urticarias have been incorporated into this document. It is expected that this article will supplement recent international guidelines with the contribution of an expert panel designated by the WAO, increasing awareness of the importance of urticaria and angioedema in medical practice and will become a useful source of information for optimum patient management worldwide.

    Angioedema is an asymmetric non-pitting oedema on face, lips, tongue and mucous membranes; any delay in diagnosis and treatment can be fatal. Treatment with lisinopril as an angiotensin converting enzyme (ACE) inhibitor, can be a reason of angioedema. Here we report a case who developed oral-facial edema four years after using lisinopril/hydrochlorothiazide. Laryngeal oedema is a main cause of death in angioedema. The treatment of choice in angioedema including fresh frozen plasma, C1 inhibitor concentrations and BRK-2 antagonists (bradykinin B2 receptor antagonists) were used. In this case; a 77 years old female patient suffering from hypertension was considered. This patient was suffering two days from swelling on her face and neck. Non- allergic angioedema was distinguished in five major forms; acquired (AAO), hereditary (HAE), renin-angiotensin-aldosterone system (RAAS) blocker-dependent, pseudoallergic angioedema (PAS) and an idiopathic angioedema (IAO). She was admitted to our clinic with the diagnosis of hereditary angioedema. Patient had skin edema and life threatening laryngeal edema. In emergency department treatment was started using intravenous methylprednisolone, diphenydramine as well as inhaled and subcutaneous epinephrine simultaneously. Despite the initial treatment, the patient died due to the insufficient respiration and cardiac arrest. The patient has no history of kidney disease.

    Objective. To asses a cohort of 105 consecutive patients with angiotensin converting enzyme-inhibitor induced angioedema with regard to demographics, risk factors, family history of angioedema, hospitalization, airway management, outcome, and use of diagnostic codes used for the condition. Study Design. Cohort study. Methods. This was a retrospective cohort study of 105 patients with angiotensin converting enzyme-inhibitor induced angioedema in the period 1995–2014. Results. The cohort consisted of 67 females and 38 males (F : M ratio 1.8), with a mean age of 63 [range 26–86] years. Female gender was associated with a significantly higher risk of angiotensin converting enzyme-inhibitor induced angioedema. 6.7% had a positive family history of angioedema. Diabetes seemed to be a protective factor with regard to angioedema. 95% experienced angioedema of the head and neck. 4.7% needed intubation or tracheostomy. 74 admissions took place during the study period with a total of 143 days spent in the hospital. The diagnosis codes most often used for this condition were “DT783 Quincke's oedema” and “DT78.4 Allergy unspecified”. Complement C1 inhibitor was normal in all tested patients. Conclusion. Female gender predisposes to angiotensin converting enzyme-inhibitor induced angioedema, whereas diabetes seems to be a protective factor. PMID:28286522

    Full Text Available A 54-year-old female presented with recurrent, widespread, erythematous, painful plaques, over a 3-month period. Skin biopsy was compatible with interstitial granulomatous dermatitis. Additional investigation revealed hypothyroidism and positive anti-thyroid antibodies. Normalization of thyroid function and high-potency topical corticosteroids provided only transitory improvement of the dermatosis. Interstitial granulomatous dermatitis is a histologic inflammatory reaction, with variable cutaneous expression. It has been reported in association with several drugs, lymphoproliferative diseases and autoimmune disorders, such as rheumatoid arthritis, systemic lupus erythematosus and vasculitis, but association with autoimmune thyroiditis is rare. Optimal therapy for this condition is yet to be established, but topical corticosteroids have been a mainstay of treatment. In most cases, this disease is characterized by flares and remissions.Uma doente de 54 anos foi avaliada por placas eritematosas, dolorosas, disseminadas, recorrentes, com 3 meses de evolução. A biopsia cutânea foi compatível com dermatite intersticial granulomatosa. Os restantes exames laboratoriais revelaram hipotiroidismo e anticorpos anti-tiroideus positivos. Apesar da normalização da função tiroideia e de tratamento com corticóide tópico de alta potência, a dermatose melhorou apenas parcialmente. Dermatite intersticial inflamatória é um diagnóstico histopatológico, com expressão clínica variável. Tem sido associada a vários fármacos, doenças linfoproliferativas e autoimunes, nomeadamente artrite reumatóide, lupus eritematoso sistémico e vasculites, mas a associação com tireoidite autoimune é rara. Até ao momento, não foi definido nenhum tratamento específico, mas os corticóides tópicos são dos fármacos mais utilizados. A doença caracteriza-se por períodos de agravamento e remissão.

    Burden of illness studies and evaluation of health-related quality of life using validated questionnaires have become an important task in the comprehensive management of angioedema conditions, mainly angioedema associated with chronic spontaneous urticaria and hereditary angioedema caused by C1-inhibitor deficiency. A review of the principal tools and studies is presented. Both diseases present a higher proportion of psychiatric disorders, impair work and studies productivity, and produce high direct and indirect costs. These assessments also have been useful to evaluate the positive impact of new drugs and interventions. More studies are desirable, especially in other types of angioedema disorders, such as hereditary angioedema with normal C1 inhibitor. Copyright © 2017 Elsevier Inc. All rights reserved.

    2016-12-01

    The definition of angioedema is an edema of subcutaneous and submucosal tissues due to increased vascular permeability and fluid extravasation. It can affect different areas, including extremities, genitals, upper airways and intestinal mucosa. The symptoms are disabling and this condition can be fatal if it involves the larynx. We can distinguish different forms of angioedema (hereditary and acquired) with different pathogenetic mechanisms, therefore responding to different treatments. Bradykinin-mediated angioedema (such as hereditary angioedema due to C1-inhibitor deficiency) does not respond to the standard therapy used for histamine-mediated angioedema. These forms should be immediately recognized and specific treatment should be used. In addition, when a patient manifests hypotension not responding to fluid replacement and associated with diffuse edema, hypoalbuminemia and hemoconcentration, we should consider the diagnosis of idiopathic systemic capillary leak syndrome, a very rare but fatal condition.

    Systemic allergic reactions, which include angioedema, are very common in clinical practice. There is great diversity in the etiological factors known to trigger angioedema, and in the pathogenetic mechanisms defining this condition. Beside the broad spectrum of immuno-allergic reactions involved in the angioedemic pathogenesis, this condition is known to also develop on the background of other disorders. These disorders may be of different etiology and have different pathogenesis (either non-immune or immune) but have one common feature referred to as "serological overlap". From research and clinical perspective, it is interesting to explore the combination of some rare neurological diseases, such as myopathies and in particular muscular dystrophies with systemic allergic reactions such as angioedema, urticaria and others. It is known that progressive muscular dystrophies (PMD) are hereditary diseases with different types of inheritance--X-chromosome recessive, X-chromosome dominant, autosomal dominant and others. In some forms, such as Duchenne muscular dystrophy (DMD), an increased expression of perforin in muscle is found which is evidence for involvement of the cellular immune response in the pathogenesis of myopathy. It is in this sense that it is interesting to explore and discuss a clinical case diagnosed as a facioscapulohumeral form of PMD, which also manifests angioedema with urticaria. We present a 41-year-old male hospitalized in the Division of Occupational Diseases and Allergology at St. George University Hospital in Plovdiv who suffered two incidents of massive angioedema on the face, back and chest, accompanied by an itchy urticarial rash. In 1985, after hospitalization to the Clinic of Neurology, he was diagnosed with PMD of facioscapulohumeral type. The medical history could not reveal any of the most common etiologic factors such as drugs, food, insects and other allergens that may be associated with the systemic allergic reactions. The

    Type III hereditary angioedema is a rare familial disorder that has recently been described as a separate condition. Triggers for episodes of angioedema include surgery, dental procedures, and tracheal intubation maneuvers. Since episodes affecting the upper airway are potentially life-threatening, prophylactic treatment is recommended in these situations. The use of icatibant (Firazyr(®)), for prevention of angioedema prior to tracheal intubation, is reported in a patient with type iii hereditary angioedema. A literature review on the anesthetic management of this condition was conducted. Copyright © 2013 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.

    The incidence of angiotensin-converting enzyme (ACE) inhibitor-associated angioedema is increased in patients with seasonal allergies. We tested the hypothesis that patients with ACE inhibitor-associated angioedema present during months when pollen counts are increased. Cohort analysis examined the month of presentation of ACE inhibitor-associated angioedema and pollen counts in the ambulatory and hospital setting. Patients with ACE inhibitor-associated angioedema were ascertained through (1) an observational study of patients presenting to Vanderbilt University Medical Center, (2) patients presenting to the Marshfield Clinic and participating in the Marshfield Clinic Personalized Medicine Research Project, and (3) patients enrolled in The Ongoing Telmisartan Alone and in Combination with Ramipril Global Endpoint Trial (ONTARGET). Measurements include date of presentation of ACE inhibitor-associated angioedema, population exposure to ACE inhibitor by date, and local pollen counts by date. At Vanderbilt, the rate of angioedema was significantly associated with tree pollen months (P = .01 from χ(2) test). When separate analyses were conducted in patients with a history of seasonal allergies and patients without, the rate of ACE inhibitor-associated angioedema was increased during tree pollen months only in patients with a history of seasonal allergies (P = .002). In Marshfield, the rate of angioedema was significantly associated with ragweed pollen months (P = .025). In ONTARGET, a positive trend was observed between the ACE inhibitor-associated angioedema rate and grass season, although it was not statistically significant (P = .057). Patients with ACE inhibitor-associated angioedema are more likely to present with this adverse drug event during months when pollen counts are increased.

  10. Socioeconomic burden of hereditary angioedema: results from the hereditary angioedema burden of illness study in Europe

    Science.gov (United States)

    2014-01-01

    Background Hereditary angioedema (HAE) due to C1 inhibitor deficiency is a rare but serious and potentially life-threatening disease marked by spontaneous, recurrent attacks of swelling. The study objective was to characterize direct and indirect resource utilization associated with HAE from the patient perspective in Europe. Methods The study was conducted in Spain, Germany, and Denmark to assess the real-world experience of HAE via a cross-sectional survey of HAE patients, including direct and indirect resource utilization during and between attacks for patients and their caregivers over the past 6 months. A regression model examined predictors of medical resource utilization. Results Overall, 164 patients had an attack in the past 6 months and were included in the analysis. The most significant predictor of medical resource utilization was the severity of the last attack (OR 2.6; p < 0.001). Among patients who sought medical care during the last attack (23%), more than half utilized the emergency department. The last attack prevented patients from their normal activities an average of 4–12 hours. Patient and caregiver absenteeism increased with attack severity and frequency. Among patients who were working or in school (n = 120), 72 provided work/school absenteeism data, resulting in an estimated 20 days missing from work/school on average per year; 51% (n = 84) indicated that HAE has hindered their career/educational advancement. Conclusion HAE poses a considerable burden on patients and their families in terms of direct medical costs and indirect costs related to lost productivity. This burden is substantial at the time of attacks and in between attacks. PMID:24996814

    2016-01-01

    Angioedema is a vascular reaction involving the lower dermis, subcutis and/or submucosal tissue and causing a temporary localized swelling in any part of the body. For many health care professionals, the diagnosis presents an ongoing challenge; several disorders may manifest with subcutaneous or submucosal swelling and falsely be assumed to be angioedema. The clinicians at the emergency department and in the immunology/allergy clinics must be skilled at recognizing the features of angioedema and its differential diagnosis. The review is based on a literature search with specific indexing terms in PubMed, a review of bibliographies and the authors' clinical experience. The most essential diseases that mimic angioedema, the so-called pseudoangioedemas, will each be discussed and illustrated by clinical photos, pointing out key features that help clarify the diagnoses and differentiate these from classic angioedema. A variety of dermatologic conditions can cause swelling that resembles angioedema, some with a potentially fatal outcome if misdiagnosed. Knowledge of pseudoangioedema is fundamental in the emergency setting when handling patients with edema and should be kept in mind when assessing an atypical angioedema case. © 2016 S.

    2017-02-01

    Angioedema, a sudden, self-limited swelling of localized areas of any part of the body that may or may not be associated with urticaria, is thought to be the result of a mast-cell mediated process versus a bradykinin etiology. Understanding the mechanism is key in determining the proper treatment. Areas Covered: Clinical presentation of varying angioedema types may be similar; however, the appropriate treatment algorithm is dependent upon clinicians' knowledge of the underlying pathophysiology and classification of angioedema. Literature review of recent guidelines, available medications, and alternative therapies was completed to provide an overview of options. There are no formal guidelines for treatment of acute or chronic histamine-mediated angioedema, and therefore, algorithms for the treatment of acute and chronic urticaria should be followed until such information becomes available. Differentiating histamine-mediated versus bradykinin mediated angioedema is essential, as treatments and treatment responses are quite different. Further research is needed to better understand idiopathic angioedema that is unresponsive to H1/H2 antagonists, LTMAs, or medications designed to treat bradykinin-mediated angioedema.

  14. Angioedema Spotlight: A Closer Examination of Sacubitril/Valsartan Safety Results.

    2017-01-01

    Incorporation of neprilysin inhibition into heart failure pharmacotherapy regimens has recently been recommended by U.S. guidelines, based on results from the PARADIGM-HF trial comparing sacubitril/valsartan to enalapril. While most of the discussion has focused on efficacy, a closer examination of the safety results, particularly the incidence of angioedema during the run-in and double-blind periods, is also warranted. Although no major safety concerns were identified, an angioedema risk comparable to enalapril was found, primarily in the black population. Therefore, despite combination with an angiotensin receptor blocker, which historically has a lower incidence of angioedema, the addition of neprilysin inhibition yields an angioedema risk profile comparable to angiotensin converting enzyme (ACE) inhibitors. Clinicians should recognize this safety risk when prescribing sacubitril/valsartan and remain vigilant in counseling patients regarding the signs and symptoms of angioedema. As recommended by the guidelines, avoiding sacubitril/valsartan use concurrently or within 36 hours of the last dose of an ACE inhibitor or in patients with a history of angioedema is also crucial to minimize angioedema risk and prevent patient harm. © Copyright 2017 by the American Board of Family Medicine.

    2013-01-01

    Objective The objective of this study was to identify genetic variants associated with angiotensin-converting enzyme (ACE) inhibitor-associated angioedema. Participants and methods We carried out a genome-wide association study in 175 individuals with ACE inhibitor-associated angioedema and 489 ACE inhibitor-exposed controls from Nashville (Tennessee) and Marshfield (Wisconsin). We tested for replication in 19 cases and 57 controls who participated in Ongoing Telmisartan Alone and in Combination with Ramipril Global Endpoint Trial (ONTARGET). Results There were no genome-wide significant associations of any single-nucleotide polymorphism (SNP) with angioedema. Sixteen SNPs in African Americans and 41 SNPs in European Americans were associated moderately with angioedema (Pangioedema in the Nashville/Marshfield sample and ONTARGET. In a candidate gene analysis, rs989692 in the gene encoding neprilysin (MME), an enzyme that degrades bradykinin and substance P, was significantly associated with angioedema in ONTARGET and Nashville/Marshfield African Americans. Conclusion Unlike other serious adverse drug effects, ACE inhibitor-associated angioedema is not associated with a variant with a large effect size. Variants in MME and genes involved in immune regulation may be associated with ACE inhibitor-associated angioedema. PMID:23838604

    2015-07-01

    Angiotensin II receptor antagonists have been proposed as a replacement therapy after the occurrence of either an angiotensin converting enzyme (ACE) inhibitor-induced angioedema or cough. However, recent studies indicate that angioedema is associated with elevated bradykinin levels in a small fraction of patients treated with angiotensin-II-receptor blockers, suggesting a common pathophysiological mechanism. To date, a standard treatment for angiotensin II receptor blocker-induced angioedema does not exist. We present a case series of patients admitted to our hospital due to angioedema induced by an angiotensin II receptor blocker. The patients were either treated with either icatibant (n = 3) or prednisolone-21-hydrogen succinate/clemastine (n = 5). Both patient groups were compared with an untreated patient cohort (n = 3). All patients were previously diagnosed with essential hypertonia. Icatibant was an effective therapy for angiotensin II receptor blocker-induced angioedema. Full symptom recovery was achieved after 5 to 7 hours, whereas symptom remission occurred within 27 to 52 and 24 to 54 hours in patients treated with Solu-Decortin prednisolone/clemastine and untreated patients, respectively. The recovery time for icatibant was similar to that described in previous studies regarding the therapeutic efficacy of icatibant for the treatment of hereditary angioedema and patients suffering from angiotensin converting enzyme inhibitor-induced angioedema. Icatibant is a safe and effective substance for the treatment of angiotensin II receptor blocker-induced angioedema. Although the pathophysiology of angiotensin II receptor blocker-induced angioedema remains unclear, it appears to be associated with the bradykinin pathway. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

Manifesta-se com alterações das funções psicológicas e pode surgir apenas com sintomas  psiquiátricos  isolados. Frequentemente, o contacto inicial com estes doentes é realizado pelo psiquiatra. Deste modo, é essencial a consideração desta patologia como diagnóstico  diferencial, visto a sua deteção e tratamento precoces melhorarem consideravelmente o prognóstico de vários tipos de neoplasias. Objetivo: O objetivo deste trabalho foi abordar a encefalite límbica autoimune como diagnóstico diferencial em doentes com sintomas neuropsiquiátricos. Métodos: Foi realizada uma pesquisa bibliográfica na base de dados PubMed com as seguintes palavras: limbic encephalitis, psychiatric. Resultados e Conclusão: A associação entre os diversos tipos de anticorpos e os diferentes quadros psiquiátricos é de destacar, revelando que os distúrbios paraneoplásicos fornecem, assim, exemplos específicos de como autoanticorpos podem afetar a função neuronal. A deteção e tratamento precoces desta patologia são essenciais. É ainda necessário realçar o papel das doenças autoimunes no conhecimento das doenças psiquiátricas em geral.

    Full Text Available Artrite reumatóide é uma doença difusa do tecido conjuntivo que se caracteriza pelo acometimento articular e sistêmico. Disfunções hematológicas como anemia ocorrem em até 65% dos pacientes, sendo a anemia das doenças crônicas a forma mais comum. A anemia hemolítica auto-imune pode estar associada à difusa do tecido conjuntivo, sendo classicamente associada ao lúpus eritematoso sistêmico e fazendo parte dos seus critérios de classificação. A presença de anemia hemolítica auto-imune em artrite reumatóide é relatada raramente na literatura e os mecanismos etiopatogênicos para o seu desenvolvimento ainda não estão esclarecidos. Descrevemos um caso de artrite reumatóide no adulto e outro de artrite reumatóide juvenil que desenvolveram anemia hemolítica auto-imune e discutimos os prováveis mecanismos etiopatogênicos envolvidos.Rheumatoid arthritis is a connective tissue disease characterized by articular and systemic involvement. Hematological abnormalities such as anemia may occur in up to 65% of the patients, with chronic disease anemia being the commonest form. Autoimmune hemolytic anemia can be associated with different connective tissue diseases, particularly systemic lupus erythematosus and it is part of its classification criteria. On the other hand, the presence of autoimmune hemolytic anemia in rheumatoid arthritis has rarely been described in the literature and the pathogenic mechanisms for its development remain unclear. We describe here a case of rheumatoid arthritis and another of juvenile rheumatoid arthritis that developed to autoimmune hemolytic anemia and present the probable etiopathogenic mechanisms.

    Angioedema is a rare condition which manifests as sudden localised, non-pitting swelling of certain body parts including skin and mucous membranes. It is vital that anaesthesiologists understand this condition, as it may present suddenly in the perioperative period with airway compromise. To identify literature for this review, the authors searched the PubMed, Medline, Embase, Scopus and Web of Science databases for English language articles covering a 10-year period, 2006 through 2016. Angioedema can be either mast-cell mediated or bradykinin-induced. Older therapies for histaminergic symptoms are well known to anaesthesiologists (e.g., adrenaline, anti-histamines and steroids), whereas older therapies for bradykinin-induced symptoms include plasma and attenuated androgens. New classes of drugs for bradykinin-induced symptoms are now available, including anti-bradykinin, plasma kallikrein inhibitor and C1 esterase inhibitors. These can be used prophylactically or as rescue medications. Anaesthesiologists are in a unique position to coordinate perioperative care for this complex group of patients. PMID:27601734

Angioedema can be either mast-cell mediated or bradykinin-induced. Older therapies for histaminergic symptoms are well known to anaesthesiologists (e.g., adrenaline, anti-histamines and steroids, whereas older therapies for bradykinin-induced symptoms include plasma and attenuated androgens. New classes of drugs for bradykinin-induced symptoms are now available, including anti-bradykinin, plasma kallikrein inhibitor and C1 esterase inhibitors. These can be used prophylactically or as rescue medications. Anaesthesiologists are in a unique position to coordinate perioperative care for this complex group of patients.

    Full Text Available Abdominal angioedema is a less recognized type of angioedema, which can occur in patients with hereditary angioedema (HAE. The clinical signs may range from subtle, diffuse abdominal pain and nausea, to overt peritonitis. We describe two cases of abdominal angioedema in patients with known HAE that were diagnosed in the emergency department by point-of-care (POC ultrasound. In each case, the patient presented with isolated abdominal complaints and no signs of oropharyngeal edema. Findings on POC ultrasound included intraperitoneal free fluid and bowel wall edema. Both patients recovered uneventfully after receiving treatment. Because it can be performed rapidly, requires no ionizing radiation,and can rule out alternative diagnoses, POC ultrasound holds promise as a valuable tool in the evaluation and management of patients with HAE.

  6. Amitriptyline and bromazepam in the treatment of vibratory angioedema: which role for neuroinflammation?

    Guarneri, Fabrizio; Guarneri, Claudio; Marini, Herbert Ryan

    2014-01-01

    Vibratory angioedema is a rare form of physical urticaria, hereditary or acquired, which occurs at body sites exposed to vibrations. Pathogenic mechanisms of disease are not completely clear and, consequently, current pharmacological treatment is sometimes unsatisfactory. We report the case of a horn player affected by acquired vibratory angioedema, relapsing after prolonged use of the instrument and resistant to systemic antihistamines and corticosteroids, which successfully responded to therapy with low doses of amitriptyline and bromazepam. A neuroinflammatory mechanism can be likely implicated in the pathogenesis of vibratory angioedema, in line with many different cutaneous/mucosal diseases involving a complex interplay of homeostatic/allostatic systems. Furthermore, in mucosal diseases, such as vibratory angioedema, physical/psychological stressors have a relevant role. In such cases, because of the complex interplay between nervous and immune system, the pharmacological activity of benzodiazepines and typical antidepressants may downregulate neuroinflammation. © 2014 Wiley Periodicals, Inc.

    Bowel angioedema is an acute adverse reaction to iodinated contrast media (CM) that involves the gastrointestinal tract. We aimed to investigate the incidence and predisposing factors of iodinated CM-associated bowel angioedema during computed tomography (CT) examinations. This study was approved by our institutional review board, and informed consent was waived due to its retrospective design. From July 2013 to July 2015, adult patients with a history of adverse reactions to iodinated CM during CT (group A, n = 427) and patients without adverse reactions matched for age and sex with the propensity-score matching method (group B, n = 427) were studied. Contrast media-associated bowel angioedema was determined when bowel wall thickness increased after contrast enhancement compared with the precontrast scan. Potential predisposing factors including patient demographics, symptoms and time of adverse reactions, and CM-related factors were compared between patients with and without angioedema in group A. In addition, the incidence of bowel angioedema was compared between groups A and B. The incidence of CM-associated bowel angioedema in group A was 3.3% (14/427) in the per-patient analysis and 2.6% (15/578) in the per-examination analysis. The CM-associated bowel angioedema involved the distal duodenum and/or proximal jejunum and showed long-segmental circumferential bowel wall thickening on CT. None of the studied predisposing factors was different between patients with and without bowel angioedema (P > 0.05). The incidence of CM-associated bowel angioedema in group B was 1.9% (8/427) and 1.7% (8/458) for per-patient and per-examination analyses, respectively, and these rates were not significantly different between groups A and B (P = 0.346 and P = 0.370, respectively). The incidence of CM-associated bowel angioedema during CT was 1.7% to 3.3%, and none of the studied predisposing factors was associated with bowel angioedema.

    Angioedema occurs in up to 2% of those taking angiotensin-converting enzyme (ACE) inhibitors. Upper airway angioedema may potentially require endotracheal intubation or cricothyrotomy, and is usually unresponsive to adrenaline. The bradykinin receptor antagonist icatibant is proven to be effective in the treatment of acute attacks of hereditary angioedema, and has also been reported effective in the treatment of angioedema associated with ACE inhibitors. To describe the use of icatibant for ACE inhibitor-associated airway angioedema. We treated 13 consecutive emergency department (ED) patients, who had not improved with adrenaline and/or corticosteroids, with icatibant 30 mg subcutaneously for ACE inhibitor-associated upper respiratory tract angioedema according to an agreed protocol. Four patients were intubated in the ED either before or after receiving icatibant; three of these were extubated within 24 h of treatment. Eight patients received early icatibant and did not require intubation. The time from onset of airway angioedema to ED presentation ranged from 1 h to 3 days (median 4 h); from ED presentation to receiving icatibant, from 30 minutes to 3 days (median 3 h); and to onset of symptom improvement after icatibant, 15 minutes to 7 h (median 2 h). One patient received a second dose of icatibant. All patients improved after receiving icatibant, consistent with its bradykinin receptor blocking mechanism. Icatibant rapidly reversed symptoms, and appeared to avert the need for intubation or expedite extubation. Timely use of icatibant in ACE inhibitor-associated angioedema may avert the need for invasive airway procedures and intensive care unit admission. © 2015 Royal Australasian College of Physicians.

    Hereditary angioedema (HAE) is rare autosomal dominant disease, characterised by spontaneous and recurrent swellings in various parts of the body. The main inflammatory factor in HAE is bradykinin (a key mediator of non-allergic angioedema) and it is responsible for capillary leak. C1 esterase inhibitor (C1-INH) is a protease inhibitor that blocks the activation of the classic complement pathway, but there are also many others biochemical pathways, including kinin. Type I HAE is defi...

  13. ACE-I Angioedema: Accurate Clinical Diagnosis May Prevent Epinephrine-Induced Harm

    Full Text Available Introduction: Upper airway angioedema is a life-threatening emergency department (ED presentation with increasing incidence. Angiotensin-converting enzyme inhibitor induced angioedema (AAE is a non-mast cell mediated etiology of angioedema. Accurate diagnosis by clinical examination can optimize patient management and reduce morbidity from inappropriate treatment with epinephrine. The aim of this study is to describe the incidence of angioedema subtypes and the management of AAE. We evaluate the appropriateness of treatments and highlight preventable iatrogenic morbidity. Methods: We conducted a retrospective chart review of consecutive angioedema patients presenting to two tertiary care EDs between July 2007 and March 2012. Results: Of 1,702 medical records screened, 527 were included. The cause of angioedema was identified in 48.8% (n=257 of cases. The most common identifiable etiology was AAE (33.1%, n=85, with a 60.0% male predominance. The most common AAE management strategies included diphenhydramine (63.5%, n=54, corticosteroids (50.6%, n=43 and ranitidine (31.8%, n=27. Epinephrine was administered in 21.2% (n=18 of AAE patients, five of whom received repeated doses. Four AAE patients required admission (4.7% and one required endotracheal intubation. Epinephrine induced morbidity in two patients, causing myocardial ischemia or dysrhythmia shortly after administration. Conclusion: AAE is the most common identifiable etiology of angioedema and can be accurately diagnosed by physical examination. It is easily confused with anaphylaxis and mismanaged with antihistamines, corticosteroids and epinephrine. There is little physiologic rationale for epinephrine use in AAE and much risk. Improved clinical differentiation of mast cell and non-mast cell mediated angioedema can optimize patient management.

    2016-09-01

    Orolingual angioedema is a rare adverse effect of tissue plasminogen activator (tPA), with an incidence of 1% to 5%. There are currently no published reports describing resolution of tPA-induced orolingual angioedema with complement inhibitor therapy. A 72-year-old man receiving home angiotensin-converting enzyme inhibitor therapy presented to the emergency department with newly developed orolingual angioedema after treatment with tPA for acute ischemic stroke. Therapy was initiated with intravenous methylprednisolone 125 mg, famotidine 20 mg, and diphenhydramine 50 mg, without significant improvement. Because of increased concern for airway protection, plasma-derived C1 esterase inhibitor was administered. Concerns about progressive and airway-threatening orolingual angioedema subsided 2 hours after administration, and invasive airway maneuvers were avoided. Orolingual angioedema is an infrequent, severe adverse effect of tPA for treatment of acute ischemic stroke. Complement inhibitors may be an additional therapeutic option for patients presenting with orolingual angioedema with potential airway compromise that is refractory to standard anaphylactic therapies.

    2016-01-01

    To evaluate whether activated partial thromboplastin time (APTT) could be used in the laboratory diagnosis of hereditary or acquired angioedema (HAE or AAE) with and without C1 inhibitor (C1-INH) deficiency. In a prospective investigation, APTT and other coagulation parameters were determined in 149 adult patients with various types of angioedema and in 26 healthy participants (HP). Mean APTT was significantly shortened in HAE-C1-INH type I (p angioedema, 4/30 (13.3%) patients with nonhistaminergic angioedema and in 2/26 (7.7%) HP. Thus, a shortened APTT was obtained in 8-9 times more patients with angioedema due to C1-INH deficiency when compared to patients with various forms of angioedema with normal C1-INH and also to HP. A shortened APTT may help to diagnose HAE-C1-INH and AAE-C1-INH when determination of C1-INH is not yet available. © 2016 S. Karger AG, Basel.

    Angioedema of the upper aerodigestive tract can lead to significant airway obstruction. To date no articles have delineated risk factors for progression after initial evaluation. This article presents the results of a retrospective study of patients with angioedema at a single institution. Patients included were consecutive otolaryngology consultations for angioedema in the emergency department (ED) from 1999 to 2003. All patients were evaluated by an otolaryngologist and underwent fiber-optic laryngoscopy, which was repeated serially depending on findings. Data was collected on demographics, comorbidities, intubation, disposition, and progression of angioedema. A total of 177 patients were included in the study: 32 (18%) patients required intubation; 25 (14%) on initial presentation and 7 (4%) who progressed from an initially stable airway to requiring intervention after reevaluation. Analysis of variance (ANOVA) demonstrated a statistically significant variance between location of edema and rate of intubation, with higher rates in the pharynx and larynx vs the lip and face. Patients who required intubation after progression between serial evaluations were statistically more likely to have edema that involved deeper portions of the aerodigestive tract. Patients who required intubation were statistically more likely to be older (average age 61.8 vs 55.1 years, p = 0.03). In this large series of patients managed for aerodigestive angioedema we demonstrate risk factors associated with airway intervention, and risk factors associated with clinical progression on serial examination to airway intervention. In addition, we demonstrate a successful management algorithm for patients with aerodigestive angioedema. © 2014 ARS-AAOA, LLC.

    Hereditary angioedema is an autosomal dominant primary immunodeficiency caused by a deficiency of the C1 inhibitor protein and characterized by recurrent episodes of subcutaneous and mucosal edema. Unpredictable and frequent crisis of angioedema affect the quality of life of individuals suffering this kind of disorder. To analyze the clinical characteristics of a family with an index case of hereditary angioedema and to determine the impact of this disease on their quality of life. Twenty six members of the family were included in the trial; 25 of them were analyzed for C4 complement and antigenic and functional C1 inhibitor blood levels. Two instruments (SF-365 and KIDSCREEN-27) were used to evaluate adult health quality and children and teenagers quality of life, respectively. Eighty three percent (83%) of individuals reporting symptoms of the condition exhibited serological criteria of hereditary angioedema type I: low levels of both C4 complement and quantitative (antigenic) and qualitative (functional) C1 inhibitor. In relation to patients' psychological and emotional performance, their quality of life was significantly affected by the symptoms of hereditary angioedema. This study provides evidence of the first family in Valle de Aburrá (Colombia) characterized as having hereditary angioedema type I. Despite the use of a generic instrument, the negative impact on the quality of life of individuals suffering this disease was also confirmed.

    2013-11-01

    Hereditary angioedema (HAE) is a rare genetic disease characterized by long-term recurrent attacks of subcutaneous or submucosal edema in different parts of the body. A comprehensive review of the literature on burden of illness for patients with HAE is presented. A Boolean search was performed using MEDLINE and EMBASE databases and the Internet. Articles discussing aspects of the burden of illness in HAE were selected. Topics focused on the course of the disease, nature of attacks, treatment, quality of life, and costs. Hereditary angioedema is associated with a significant and multifaceted disease burden. Diagnosis is often delayed for years, with patients receiving ineffective treatment and unnecessary medical procedures before diagnosis. HAE attacks are painful, unpredictable, and debilitating and often require emergency medical attention. Attacks can affect a patient's daily activities, including work or schooling. Depression and anxiety are prevalent in patients with HAE. Recent advances in treatment provide patients with effective and well-tolerated prophylactic and on-demand therapeutic options. However, end points specific to HAE that better measure the impact of treatment on disease burden are lacking. Furthermore, there is a notable paucity of literature directed toward physicians who are instrumental in diagnosing and treating patients with HAE (eg, emergency department). More publications are broadening the understanding of HAE. However, important gaps remain. Effective management of HAE requires a more comprehensive understanding of the disease burden so that disease management can be individualized to meet specific patient needs.

    Hereditary angioedema (HAE) is a chronic disease with a high burden of disease that is poorly understood and often misdiagnosed. Availability of treatments, including C1 esterase inhibitor (C1INH) replacement, ecallantide, and icatibant, marks a significant advance for HAE patients. We aimed to better understand the current state of HAE care, from a patient perspective, after the introduction of several novel therapies. One session of the United States Hereditary Angioedema Association 2013 patient summit was devoted to data collection for this study. Patients attending the summit were self-selected, and HAE diagnosis was self-reported. Survey questions assessed patient characteristics, burden of disease, and treatment. Participant responses were captured using an audience response system. We surveyed 149 (80%) type I and II HAE (HAE-C1INH) and 37 (20%) HAE with normal C1INH (HAE-nlC1INH) patients. HAE-C1INH (72%) and HAE-nlCINH patients (76%) equally reported that HAE had a significant impact on quality of life (QOL). A third of HAE-C1INH patients were diagnosed within one year of their first HAE attack, but another third reported a delay of more than 10 years. Most HAE-C1INH (88%) and HAE-nlC1INH (76%) patients had on-demand treatment available. HAE-C1INH patients frequently had an individual treatment plan (76%) compared with 50% of HAE-nlC1INH patients. Most HAE-C1INH patients went to the emergency department (ED) or were hospitalized less than once every six months (80%). Our findings show that HAE management is improving with good access to on-demand and prophylactic treatment options. However, HAE patients still have a significant burden of disease and continued research and educational efforts are needed. PMID:25976438

    Full Text Available M Aamir Ali, Marie L Borum Division of Gastroenterology and Liver Diseases, George Washington University, Washington, DC, USA Abstract: Up to 93% of patients with hereditary angioedema (HAE experience recurrent abdominal pain. Many of these patients, who often present to emergency departments, primary care physicians, general surgeons, or gastroenterologists, are misdiagnosed for years and undergo unnecessary testing and surgical procedures. Making the diagnosis of HAE can be challenging because symptoms and attack locations are often inconsistent from one episode to the next. Abdominal attacks are common and can occur without other attack locations. An early, accurate diagnosis is central to managing HAE. Unexplained abdominal pain, particularly when accompanied by swelling of the face and extremities, suggests the diagnosis of HAE. A family history and radiologic imaging demonstrating edematous bowel also support an HAE diagnosis. Once HAE is suspected, C4 and C1 esterase inhibitor (C1-INH laboratory studies are usually diagnostic. Patients with HAE may benefit from recently approved specific treatments, including plasma-derived C1-INH or recombinant C1-INH, a bradykinin B2-receptor antagonist, or a kallikrein inhibitor as first-line therapy and solvent/detergent-treated or fresh frozen plasma as second-line therapy for acute episodes. Short-term or long-term prophylaxis with nanofiltered C1-INH or attenuated androgens will prevent or reduce the frequency and severity of episodes. Gastroenterologists can play a critical role in identifying and treating patients with HAE, and should have a high index of suspicion when encountering patients with recurrent, unexplained bouts of abdominal pain. Given the high rate of abdominal attacks in HAE, it is important for gastroenterologists to appropriately diagnose and promptly recognize and treat HAE, or refer patients with HAE to an allergist.

All studies administered omalizumab (75, 150, or 300 mg in ASTERIA I and ASTERIA II; 300 mg in GLACIAL) or placebo subcutaneously every 4 weeks for at least 12 weeks. Urticaria Patient Daily Diary entries were completed by patients and summarized. At baseline, angioedema prevalence was higher in GLACIAL (53.1%) than in ASTERIA I (47.5%) or ASTERIA II (40.7%). The mean proportion of angioedema-free days during weeks 4 to 12 was greater for patients treated with 300 mg of omalizumab than placebo in ASTERIA I (96.1% vs 88.2%, P angioedema was managed by low-intensity interventions (doing nothing or taking medication). Treatment with 300 mg of omalizumab was efficacious in reducing patient-reported angioedema. Low-intensity interventions were generally used to manage angioedema episodes. clinicaltrials.gov Identifiers: NCT01287117 (ASTERIA I), NCT01292473 (ASTERIA II), and NCT01264939 (GLACIAL).

    The published evidence on pharmacologic approaches to the management of angiotensin-converting enzyme inhibitor (ACEI)-induced angioedema is reviewed. Angioedema is a serious, potentially life-threatening adverse effect of ACEI use. Although the underlying mechanism is not fully understood, excess bradykinin produced through a complex interplay between the kallikrein-kinin and renin-angiotensin-aldosterone systems is thought to play a major role. The nonallergic nature of the reaction renders traditional therapies (corticosteroids and antihistamines) ineffective because those agents do not modify the proposed pathophysiology. Fresh frozen plasma (FFP) provides kinase II, a protein that breaks down bradykinin. Case reports support FFP as a treatment for ACEI-induced angioedema, but no formal evaluations have been completed to date. Both ecallantide and complement 1 esterase (C1) inhibitor concentrate reduce bradykinin production through upstream inhibition of kallikrein. C1 inhibitor concentrate has been used successfully to manage ACEI-induced angioedema in a few reported cases, but robust supportive studies are lacking. Conversely, ecallantide has been evaluated in multiple randomized trials but has not been shown to offer advantages over traditional therapies. The use of icatibant, a direct antagonist of bradykinin B2 receptors, was reported to be beneficial in several case reports and in a small Phase II study, safely and rapidly reducing symptoms of ACEI-induced angioedema. An ongoing Phase III trial (NCT01919801) will better define the role of icatibant in the management of ACEI-induced angioedema. FFP, C1 inhibitor, and icatibant appear to be safe and effective therapeutic options for the management of ACEI-induced angioedema, whereas it appears ecallantide should be avoided.

    Angiotensin-converting enzyme inhibitor (ACE-I)–induced angioedema can be life-threatening without emergent intervention. The putative mediator is believed to be bradykinin, similar to hereditary angioedema, so these patients respond poorly to corticosteroids and antihistamines. This study was designed to determine characteristics and clinical outcomes of patients presenting to an emergency department (ED) with ACE-I angioedema. This was a retrospective chart review of 100 patients presenting to the ED from 2007 to 2008 with an ICD-9 code of 995.1 (angioedema) or 995.2 (drug-induced angioedema). Two hundred fifty-two patients with these ICD-9 codes were identified and placed in random order, and the first 100 meeting inclusion criteria were included. Statistical analysis was primarily descriptive. All 100 patients had an ICD-9 code of 995.1 (angioedema). Patients presented in every month, with spring months (April–June) having the most presentations (32%). The median age was 59 years, 75% were African American, and 66% were admitted to the hospital. Two patients (2%) required endotracheal intubation. Lisinopril was the most commonly prescribed ACE-I (84%). The most common symptom was moderate lip and tongue swelling (89%) followed by mild difficulty breathing (12%). Tongue swelling was significantly associated with admission. Time from symptom onset to ED presentation was not associated with need for admission. Concomitant medications did not differ between admitted and discharged patients. ACE-I angioedema is associated with significant morbidity and health care use because many patients require hospitalization, suggesting an unmet need for novel therapies targeted to treat this condition.

    Full Text Available Estudos recentes indicam a existência de um tráfego bidirecional de células durante a gestação humana normal. Células fetais persistem no sangue periférico materno por muitos anos após a gestação. Muitas doenças auto-imunes são mais prevalentes em mulheres, algumas das quais apresentam pico de incidência em fases tardias dos anos férteis femininos. A doença enxerto-versushospedeiro é uma condição conhecida de quimerismo e possui similaridades clínicas com algumas doenças auto-imunes reumáticas, notavelmente com esclerose sistêmica e síndrome de Sjögren e, algumas vezes, com lúpus eritematoso sistêmico. Este artigo explora a hipótese de que o microquimerismo fetal contribua para a patogênese de algumas doenças auto-imunes, baseado em revisões de estudos anteriores que trabalharam com esta hipótese. São apresentadas ressalvas de ordem conceitual e técnica a serem consideradas na interpretação dos dados da literatura.Recent studies indicate that there is bi-directional traffic of cells during normal human pregnancy. Fetal cells have been found to persist in the maternal peripheral blood for many years after pregnancy. Many autoimmune diseases are more prevalent in women, and some of them have peak incidence at late stages of childbearing years. Chronic graft versus host disease (cGVHD is a known condition of chimerism and has clinical similarities to some rheumatic autoimmune diseases, notably systemic sclerosis, Sjögren's syndrome and systemic lupus erythematosus. This article explores the hypothesis that fetal microchimerism contributes to the pathogenesis of some autoimmune diseases, based on reviews of previous studies that have worked with this hypothesis. Technical and conceptual considerations are presented for a critical appraisal of the available literature.

Sendo assim, ela é imunologicamente caracterizada pelo ataque celular e/ou mediada por anticorpos que gera a destruição de órgãos-alvo. Além disso, é marcada pela tríade patognomônica: candidíase crônica, hipoparatireoidismo e doença de Addison, com várias outras manifestações endócrinas e não endócrinas. Logo, o diagnóstico é feito com base na presença de duas dessas três características clássicas e o tratamento visa controlar as inúmeras deficiências que os pacientes possam apresentar. Esta revisão literária teve como objetivo a compreensão do envolvimento do gene AIRE em relação aos aspectos imunológicos presentes e, consequentemente, manifestações clínicas dessa doença. Assim, evidenciou-se a necessidade de ampliar a discussão sobre essa patologia, com o intuito de melhorar a qualidade de vida dos pacientes, mediante diagnóstico e tratamento precoces e que estejam de acordo com as manifestações clínicas de cada paciente. Desse modo, a pesquisa de caráter qualitativo envolveu artigos científicos dos periódicos eletrônicos LILACS (Literatura Latino-Americana e do Caribe, SCIELO (Scientific Electronic Library Online e NCBI (National Center for Biotechnology Information, entre os anos 2009 e 2016. Por conseguinte, nota-se a relevância dessa revisão, pois observou-se que, apesar de os autores convergirem sobre as opiniões acerca dessa síndrome, há, ainda, muitas questões obscuras no que diz respeito aos mecanismos da doença. Isso evidencia a necessidade de se promoverem mais discussões sobre esse tema.

    Acquired angioedema is a rare disorder causing recurrent life-threatening angioedema, due to decreased activity of C1 esterase inhibitor. A 57-year-old man presented to our hospital with recurrent swelling of the hands, lips, tongue, scrotum and throat. Lab examination showed the presence of an IgM kappa monoclonal antibody. Additional analysis showed that in the IgM fraction autoantibody activity against C1 esterase inhibitor was present. This confirmed the diagnosis of acquired angioedema in the presence of lymphoplasmacytic lymphoma. Despite standard therapy, there was an increase in the episodes of laryngeal oedema. Therefore it was decided to perform a non-myeloablative allogeneic haematopoietic stem cell transplantation, with his HLA-identical brother as donor. The post-transplantation course was without complications. Five years following alloSCT he is in complete remission without symptoms and with increased C1 esterase inhibitor activity. In this case all other known treatment options for severe acquired angioedema failed. This is the first case describing treatment of severe acquired angioedema, caused by lymphoplasmacytic lymphoma, with an alloSCT.

    Bradykinin-mediated angioedema is characterized by transient attacks of localized edema of subcutaneous or submucosal tissues and can be life-threatening when involving the upper airways. The aim of this study was to determine the features of acute attacks that might be associated with admission to an ICU. We carried out a retrospective, multicenter, observational study in consecutive patients attending one of six reference centers in France for acute bradykinin-mediated angioedema attacks. Patients had been hospitalized for an acute episode at least once previously. Acute attacks requiring ICU admission were compared with acute attacks that had not required ICU admission. Overall, 118 acute attacks in 31 patients were analyzed (10 patients with hereditary angioedema, 19 patients with angiotensin-converting enzyme inhibitor-induced angioedema, and two patients with acquired C1-inhibitor deficiency angioedema). In multivariate analysis, upper airway involvement, corticosteroid, and C1-inhibitor concentrate administration were associated with ICU admission. Seven episodes (18%) needed airway protection. The evolution was favorable in 38 of 39 attacks warranting ICU admission: patients were able to get out of the service (mean ICU stay 4±5 days). One death was observed by asphyxiation because of laryngeal swelling. Upper airway involvement is an independent risk factor for ICU admission. Corticosteroid use, which is an ineffective treatment, and C1-inhibitor concentrate use are factors for ICU admission. The presence of upper airway involvement should be a warning signal that the attack may be severe.

    Although angiotensin-converting enzyme (ACE) inhibitors are widely used as the first choice drug for treating hypertension, we have only a superficial understanding of their relationship to angioedema. We report a case of life-threatening angioedema. The case was a 60-year-old man who had been taking an ACE inhibitor for hypertension for 11 years. He visited his home doctor for dyspnea, and tongue and neck swelling. He was transported to our hospital because of the possibility of airway obstruction. On admission, his tongue and neck swelling became more severe. We performed an intubation using an endoscope and started airway management. We also stopped his ACE inhibitor. The severe tongue and neck swelling improved gradually and he was extubated on day 3. On the fifth day he was discharged. We diagnosed angioedema caused by an ACE inhibitor. Although the risk of airway obstruction with ACE inhibitors is acknowledged, we have only a superficial understanding of how prolonged ACE inhibitor treatment induces angioedema. So we should consider angioedema in cases of taking ACE inhibitors, especially in cases of prolonged treatment.

    Acute angioedema attacks are conventionally treated with antihistamines and steroids, in line with a presumed mechanism of disease involving overwhelming mast-cell degranulation. This approach overlooks a small but important minority of cases in which attacks are bradykinin driven and exhibit poor responsiveness to steroid or anti-histamine therapy. These patients may have a family history of angioedema (hereditary angioedema), or a past medical history including B-cell lymphoproliferative disorders or autoimmune disease (acquired angioedema). Rather than steroid therapy, they respond to administration of a bradykinin inhibitor, or more commonly, a C1 esterase inhibitor substitute, to control acute symptoms and reduce the probability of invasive airway insertion. In the long-term, they require C1 esterase inhibitor sparing therapy and a treat-the-cause approach to reduce the risk of recurrent attacks. We present here a case of a middle-aged woman who presented with recurrent angioedema of initially uncertain aetiology. © 2015 Royal College of Physicians.

The estimated prevalence of HAE in the general population is one individual per 50,000, with reported ranges from 1:10,000 to 1:150,000, without major sex or ethnic differences. Various treatment options for acute attacks and prophylaxis of HAE are authorized and available in the market, including plasma-derived (Berinert®, Cinryze®, and Cetor® and recombinant (Rhucin® and Ruconest™ C1 inhibitors, kallikrein inhibitor-ecallantide (Kalbitor®, and bradykinin B2 receptor antagonist-icatibant (Firazyr®. Some of these drugs are used only to treat HAE attacks, whereas others are only approved for prophylactic therapies and all of them have improved disease outcomes due to their different mechanisms of action. Bradykinin and its binding to B2 receptor have been demonstrated to be responsible for most of the symptoms of HAE. Thus icatibant (Firazyr®, a bradykinin B2 receptor antagonist, has proven to be an effective and more targeted treatment option and has been approved for the treatment of acute attacks of HAE. Rapid and stable relief from symptoms of cutaneous, abdominal, or laryngeal HAE attacks has been demonstrated by 30 mg of icatibant in Phase III clinical trials. Self-resolving mild to moderate local site reactions after subcutaneous injection of icatibant were observed. Icatibant is a new, safe, and effective treatment for acute attacks of HAE. HAE has been reported to result in enormous humanistic burden to patients, affecting both physical and mental health, with a negative impact on education, career, and work productivity, and with substantial

    Abstract The number of cases of acquired angioedema related to angiotensin converting enzyme inhibitors induced (ACEI-AAE) is on the increase, with a potential concomitant increase in life-threatening attacks of laryngeal edema. Our objective was to determine the main characteristics of ACEI-AAE attacks and, in doing so, the factors associated with likelihood of hospital admission from the emergency department (ED) after a visit for an attack. A prospective, multicenter, observational study (April 2012–December 2014) was conducted in EDs of 4 French hospitals in collaboration with emergency services (SAMU 93) and a reference center for bradykinin-mediated angioedema. For each patient presenting with an attack, emergency physicians collected demographic and clinical presentation data, treatments, and clinical course. They recorded time intervals from symptom onset to ED arrival and to treatment decision, from ED arrival to specific treatment with plasma-derived C1-inhibitor (C1-INH) or icatibant, and from specific treatment to onset of symptom relief. Attacks requiring hospital admission were compared with those not requiring admission. Sixty-two eligible patients with ACEI-AAE (56% men, median age 63 years) were included. Symptom relief occurred significantly earlier in patients receiving specific treatment than in untreated patients (0.5 [0.5–1.0] versus 3.9 [2.5–7.0] hours; P < 0.0001). Even though icatibant was injected more promptly than plasma-derived C1-INH, there, however, was no significant difference in median time to onset of symptom relief between the 2 drugs (0.5 [0.5–1.3] versus 0.5 [0.4–1.0] hours for C1-INH and icatibant, respectively, P = 0.49). Of the 62 patients, 27 (44%) were admitted to hospital from the ED. In multivariate analysis, laryngeal involvement and progressive swelling at ED arrival were independently associated with admission (Odds ratio [95% confidence interval] = 6.2 [1.3–28.2] and 5.9 [1.3–26

    Cough and upper airway angioedema are well-recognized adverse reactions of angiotensin-converting enzyme inhibitor (ACEI) therapy. Visceral angioedema is an infrequent and often unrecognized complication of ACEI therapy. We describe a patient in whom the diagnosis was delayed for > 2 years. A 60-year-old woman with hypertension on treatment with enalapril presented with complaints of abdominal pain and diarrhea for 2 days. Physical examination was significant for diffuse abdominal tenderness and hypotension. Laboratory data were normal except for leukocytosis and elevated creatinine. Computed tomography (CT) of the abdomen showed diffuse small bowel wall thickening. ACEI-induced visceral angioedema was considered, enalapril was discontinued and supportive care was provided. Patient's symptoms and CT appearance improved 48 and 72 hours, respectively, after stopping enalapril. She remained symptom-free 1 year after discharge.

    We describe a 39-year-old woman with an apparent captopril-induced, contact mucosal-dominant pemphigus vulgaris and angioedema, who took captopril during a bout of arterial hypertension. This exposure suggests that captopril and pathophysiology of angioedema stimulated the development of pemphigus vulgaris, which was diagnosed using the novel, indirect immunofluorescence BIOCHIP mosaic, with the modification to detect serum IgG4 autoantibodies. We discuss the patient, who experienced a chain of events leading to the active stage of pemphigus vulgaris, and review concepts of pemphigus vulgaris inducible by drugs and pathological immunity.

  7. Management of upper airway edema caused by hereditary angioedema

    Directory of Open Access Journals (Sweden)

    Farkas Henriette

    2010-07-01

    Full Text Available Abstract Hereditary angioedema is a rare disorder with a genetic background involving mutations in the genes encoding C1-INH and of factor XII. Its etiology is unknown in a proportion of cases. Recurrent edema formation may involve the subcutis and the submucosa - the latter can produce obstruction in the upper airways and thereby lead to life-threatening asphyxia. This is the reason for the high, 30-to 50-per-cent mortality of undiagnosed or improperly managed cases. Airway obstruction can be prevented through early diagnosis, meaningful patient information, timely recognition of initial symptoms, state-of-the-art emergency therapy, and close monitoring of the patient. Prophylaxis can substantially mitigate the risk of upper airway edema and also improve the patients' quality of life. Notwithstanding the foregoing, any form of upper airway edema should be regarded as a potentially life-threatening condition. None of the currently available prophylactic modalities is capable of preventing UAE with absolute certainty.

    2016-02-01

    Hereditary angioedema (HAE) patients experience recurrent local swelling in various parts of the body including painful swelling of the intestine and life-threatening laryngeal oedema. Most HAE literature is about attacks located in one anatomical site, though it is mentioned that HAE attacks may also involve multiple anatomical sites simultaneously. A detailed description of such multi-location attacks is currently lacking. This study investigated the occurrence, severity and clinical course of HAE attacks with multiple anatomical locations. HAE patients included in a clinical database of recombinant human C1-inhibitor (rhC1INH) studies were evaluated. Visual analog scale scores filled out by the patients for various symptoms at various locations and investigator symptoms scores during the attack were analysed. Data of 219 eligible attacks in 119 patients was analysed. Thirty-three patients (28%) had symptoms at multiple locations in anatomically unrelated regions at the same time during their first attack. Up to five simultaneously affected locations were reported. The observation that severe HAE attacks often affect multiple sites in the body suggests that HAE symptoms result from a systemic rather than from a local process as is currently believed.

    Full Text Available El angioedema hereditario (HAE es una enfermedad rara, autosómica dominante, caracterizada por episodios que comprometen la piel, el tracto gastrointestinal y la laringe. Tiene una mortalidad histórica por asfixia del 15 al 50%. Es producida por la deficiencia funcional del C1 inhibidor. La identificación de la bradiquinina como mediador principal ha estimulado el desarrollo de nuevos medicamentos para tratar la enfermedad. El tratamiento del HAE se establece en consensos internacionales. El desarrollo de guías para el tratamiento de la enfermedad permite ordenar el uso de procedimientos diagnósticos y drogas. Describimos aquí algunas características farmacológicas de los medicamentos utilizados en el tratamiento del HAE en la Argentina: el concentrado plasmático de C1 inhibidor, el antagonista de la bradiquinina, icatibant, el andrógeno atenuado danazol y los agentes anti-fibrinolíticos ácidos épsilon aminocaproico (EACA y tranexámico. Asimismo, se describe su forma de uso y del control de los eventos adversos más frecuentes, así como las recomendaciones del último consenso internacional, aplicables para conformar una primera guía de tratamiento del HAE en la Argentina.

    Objective To characterize the management and outcomes of life-threatening laryngeal attacks of hereditary angioedema (HAE) treated with icatibant in the observational Icatibant Outcome Survey (NCT01034969) registry. Methods This retrospective analysis was based on data from patients with HAE type I/II who received healthcare professional-administered or self-administered icatibant to treat laryngeal attacks between September 2008 and May 2013. Results Twenty centers in seven countries contributed data. Overall, 42 patients with HAE experienced 67 icatibant-treated laryngeal attacks. Icatibant was self-administered for 62.3% of attacks (healthcare professional-administered, 37.7%). One icatibant injection was used for 87.9% of attacks, with rescue or concomitant medication used for 9.0%. The median time to treatment was 2.0 h (n=31 attacks) and the median time to resolution was 6.0 h (n=35 attacks). Conclusions This analysis describes successful use of icatibant for the treatment of laryngeal HAE attacks in a real-world setting. PMID:27116379

  12. Life Threatening Idiopathic Recurrent Angioedema Responding to Cannabis

    Full Text Available We present a case of a 27-year-old man with recurrent episodes of angioedema since he was 19, who responded well to treatment with medical grade cannabis. Initially, he responded to steroids and antihistamines, but several attempts to withdraw treatment resulted in recurrence. In the last few months before prescribing cannabis, the frequency and severity of the attacks worsened and included several presyncope events, associated with scrotal and neck swelling. No predisposing factors were identified, and extensive workup was negative. The patient reported that he was periodically using cannabis socially and that during these periods he was free of attacks. Recent data suggest that cannabis derivatives are involved in the control of mast cell activation. Consequently, we decided to try a course of inhaled cannabis as modulators of immune cell functions. The use of inhaled cannabis resulted in a complete response, and he has been free of symptoms for 2 years. An attempt to withhold the inhaled cannabis led to a recurrent attack within a week, and resuming cannabis maintained the remission, suggesting a cause and effect relationship.

    Recent adverse event reports have raised the question of increased angioedema risk associated with exposure to levetiracetam. To help address this question, the Observational Health Data Sciences and Informatics research network conducted a retrospective observational new-user cohort study of seizure patients exposed to levetiracetam (n = 276,665) across 10 databases. With phenytoin users (n = 74,682) as a comparator group, propensity score-matching was conducted and hazard ratios computed for angioedema events by per-protocol and intent-to-treat analyses. Angioedema events were rare in both the levetiracetam and phenytoin groups (54 vs. 71 in per-protocol and 248 vs. 435 in intent-to-treat). No significant increase in angioedema risk with levetiracetam was seen in any individual database (hazard ratios ranging from 0.43 to 1.31). Meta-analysis showed a summary hazard ratio of 0.72 (95% confidence interval [CI] 0.39-1.31) and 0.64 (95% CI 0.52-0.79) for the per-protocol and intent-to-treat analyses, respectively. The results suggest that levetiracetam has the same or lower risk for angioedema than phenytoin, which does not currently carry a labeled warning for angioedema. Further studies are warranted to evaluate angioedema risk across all antiepileptic drugs. Wiley Periodicals, Inc. © 2017 International League Against Epilepsy.

    The pathogenesis of urticaria and angioedema induced by non-steroidal anti-inflammatory drugs (NSAIDs) is still obscure. We analyzed the clinical characteristics of patients with NSAIDs-induced urticaria and angioedema without asthma in Japan. We retrospectively collected the cases of NSAIDs-induced urticaria and angioedema from Japanese medical journals in 2000-2009. Seventy-six patients were analyzed. The male/female ratio was 1:2.5 and the mean age was 38.1 years. Urticaria was most frequent clinical manifestation in 3 groups; urticaria alone, urticaria and angioedema, and angioedema alone. Time interval from drug administration to onset was 5 minutes to 48 hours by aspirin at a dose of 25-1000 mg. Skin prick test was performed with aspirin in 33 patients, and the results were negative in all patients. Meloxicam, a selective cyclooxygenase-2 (COX-2) inhibitor, and celecoxib, a new selective COX-2 inhibitor, were administered safely in 4 of 6 patients and in 2 of 3 patients with NSAIDs-induced urticaria, respectively. These drugs were administered safely in all administered patients with NSAIDs-induced angioedema. Tiaramidehydrochroride (a basic COX-1 inhibitor) was safely used in 23 administered patients with NSAIDs-induced angioedema. Leukotriene receptor antagonists were effective in 2 of 5 patients administered, but aggravated symptoms in the others. Diversity of NSAIDs-induced urticaria and angioedema was shown in this study. Pathogenesis of NSAIDs-induced urticaria and angioedema without asthma seems to be different from that of NSAIDs-induced asthma.

    Angioedema is a localized, sudden, transient, and often recurrent swelling of the deeper layers of the skin or mucosa with no epidermal component. It is caused by vasoactive substances that produce a transient increase in endothelial permeability. Angioedema involving the laryngeal components is a life-threatening situation for the patient,and it is a challenge for the emergency medicine physician to rapidly achieve a safety airway. Most cases of laryngeal angioedema are induced by histamine release; but 10% are bradykinin induced, which does not respond to the conventional algorithm of treating allergic induced angioedema. We present a case report of an angiotensin converting enzyme (ACE) inhibitor–induced laryngeal angioedema alleviated only after treatment with the new bradykinin receptor inhibitor medication icatibant which was licensed only for use in hereditary angioedema. We reviewed the literature for the use of icatibant in acquired drug-induced angioedema; and because of the similar pathogenesis between the hereditary angioedema and the ACE inhibitor–induced angioedema,we propose an algorithm for careful use of icatibantin life-threatening angioedema in the emergency department.

    Angioedema is a condition in which an increase in vascular permeability leads to the swelling of body tissues. There are both hereditary and acquired forms of the disease, with the latter often associated with the administration of angiotensin-converting enzyme inhibitor medication. Involvement of the intestinal tract is a rare manifestation of angioedema, and can present with abdominal pain, nausea, and vomiting. It is critical for radiologists to be aware of this entity, as they may have the only opportunity to make the diagnosis. We present three cases of intestinal angioedema diagnosed on MRI with discussion of the imaging findings. Copyright © 2017 Elsevier Inc. All rights reserved.

    2014-04-01

    Hereditary angioedema (HAE) is characterized by edematous swelling attacks of the face, extremities, abdomen, genitalia, and upper airway. The potential for laryngeal swelling makes the disease life-threatening, and the swelling elsewhere contributes to the significant burden of illness. The increased risk for mental health disorders in HAE is due to the burden of disease and possibly associated activation of the immune system. To determine the prevalence of depression and anxiety in HAE patients and the most high-yield features of depression to target in a clinical encounter. Depression and anxiety symptoms were evaluated using the 29 items of the Hamilton Depression Rating Scale along with the 14-item Hamilton Anxiety Rating Scale. The sample size was 26 participants with a diagnosis of type 1 or 2 HAE drawn from a cohort of 60 adult patients. In addition, a literature search was performed regarding how immune modulation affects depression and anxiety. A total of 39% of participants were identified as experiencing depression of mild (50%), moderate (40%), or severe (10%) levels. Fifteen percent of participants displayed prominent anxiety, half of whom had mild anxiety, 25% moderate anxiety, and 25% severe anxiety. The literature on inflammation and depression suggests a possible link between HAE and depression. Our data and the literature support that depression and anxiety symptoms are common in patients with HAE and may be secondary to chronic disease burden, associated pathophysiologic features, or both. Treatment that addresses the psychosocial and mental health of HAE patients is critical for best practice. Copyright © 2014 American College of Allergy, Asthma & Immunology.

    Hereditary angioedema (HAE) is an autosomal-dominant disorder resulting from C1-inhibitor (C1INH) deficiency. Smell impairments were found in patients affected with systemic lupus erythematosus, that, similarly to HAE, is characterized by the activation of the classical complement pathway with C4 consumption. In this study, we aimed at evaluating the sense of smell in patients with HAE. Thirty patients with HAE and 30 healthy age- and sex-matched controls were evaluated for olfactory functions using the 3-stages Sniffin'-Sticks kit (threshold, discrimination, and identification [TDI]). TDI scores were analyzed according to complement levels (C1INH, C3, C4 and CH50), Beck depression inventory (BDI-II) and danazol treatment. A significant decrease in olfactory function was observed in patients affected with HAE compared with controls in total TDI score (P < 0.001), and in the discrimination (P < 0.001) and identification scores (P = 0.012). Anosmia was present only in patients with HAE (3.3%) who also exhibited more frequently hyposmia (53.3%vs 3.3%, P < 0.0001). Complement levels were reduced in patients with HAE. C4 serum levels showed positive correlation with total TDI score (P < 0.001), and with discrimination (P = 0.002) and identification (P = 0.011) scores. CH50 complement levels showed positive correlation with total TDI score (P < 0.001), and with threshold (P = 0.002) and discrimination (P = 0.011) scores. Sex, age, danazol treatment, BDI-II scores were not different between the patients and controls and did not influence TDI scores significantly. Evidence for an impaired sense of smell was found in patients with HAE. The reduction in olfactory function in these cases seems to correlate with complement C4 and CH50 levels. Immune and genetic mechanisms might play a role in this defect. © 2010 John Wiley & Sons A/S.

    Full Text Available Attacks of Hereditary Angioedema due to C1-inhibitor deficiency (C1-INH-HAEare often triggered by stressful events/hormonal changes.Our study evaluates the relationship between autonomic nervous system (ANS and contact/complement system activation.Twenty-three HAE patients (6 males, mean age 47.5±11.4 years during remission and 24 healthy controls (8 males, mean age 45.3±10.6 years were studied. ECG, beat-by-beat blood pressure, respiratory activity were continuously recorded during rest (10' and 75-degrees-head-up tilt (10'. C1-INH, C4, cleaved high molecular weight kininogen (cHK were assessed; in 16 patients and 11 controls plasma catecholamines were also evaluated. Spectral analysis of heart rate variability allowed extraction of low-(LF and high-(HF frequency components, markers of sympathetic and vagal modulation respectively.HAE patients showed higher mean systolic arterial pressure (SAP than controls during both rest and tilt. Tilt induced a significant increase in SAP and its variability only in controls. Although sympathetic modulation (LFnu increased significantly with tilt in both groups, LF/HF ratio, index of sympathovagal balance, increased significantly only in controls. At rest HAE patients showed higher noradrenaline values (301.4±132.9 pg/ml vs 210.5±89.6pg/ml, p = 0.05. Moreover, in patients tilt was associated with a significant increase in cHK, marker of contact system activation (49.5 ± 7.5% after T vs 47.1 ± 7.8% at R, p = 0.01.Our data are consistent with altered ANS modulation in HAE patients, i.e. increased sympathetic activation at rest and blunted response to orthostatic challenge. Tilt test-induced increased HK cleavage suggests a link between stress and bradykinin production.

  14. Diagnosis and screening of patients with hereditary angioedema in primary care

    2016-01-01

    Hereditary angioedema (HAE) is a rare autosomal dominant disease that commonly manifests with episodes of cutaneous or submucosal angioedema and intense abdominal pain. The condition usually presents due to a deficiency of C1 esterase inhibitor (C1-INH) that leads to the overproduction of bradykinin, causing an abrupt increase in vascular permeability. A less-understood and less-common form of the disease presents with normal C1-INH levels. Symptoms of angioedema may be confused initially with mast cell-mediated angioedema, such as allergic reactions, and may perplex physicians when epinephrine, antihistamine, or glucocorticoid therapies do not provide relief. Similarly, abdominal attacks may lead to unnecessary surgeries or opiate dependence. All affected individuals are at risk for a life-threatening episode of laryngeal angioedema, which continues to be a source of fatalities due to asphyxiation. Unfortunately, the diagnosis is delayed on average by almost a decade due to a misunderstanding of symptoms and general lack of awareness of the disease. Once physicians suspect HAE, however, diagnostic methods are reliable and available at most laboratories, and include testing for C4, C1-INH protein, and C1-INH functional levels. In patients with HAE, management consists of acute treatment of an attack as well as possible short- or long-term prophylaxis. Plasma-derived C1-INH, ecallantide, icatibant, and recombinant human C1-INH are new treatments that have been shown to be safe and effective in the treatment of HAE attacks. The current understanding of HAE has greatly improved in recent decades, leading to growing awareness, new treatments, improved management strategies, and better outcomes for patients. PMID:27194914

    Black race is a risk factor for angioedema. The primary aim was to examine the relationship between race-ethnicity and risk factors for angioedema. Using a retrospective case-control study design, data was extracted with the Clinical Looking Glass utility, a data collection and management tool that captures data from electronic medical record systems within the Montefiore Healthcare System. Cases were emergency department (ED) visits with primary or secondary International Classification of Diseases, Ninth Revision, code diagnoses of angioedema in adults aged ≥ 18 years from January 2008 to December 2013 at three Montefiore centers in Bronx, New York. Controls were a random sampling of adult ED visits during the same period. In primary analyses, angiotensin-converting enzyme inhibitor (ACE-I) and black race were evaluated for synergy. The influence of different risk factors in the development of angioedema was evaluated using logistic regression models. Finally, race-ethnicity was further explored by evaluating for effect modification by stratification of models by race-ethnicity categories. There were 1,247 cases and 6,500 controls randomly selected from a larger control pool. ACE-I use (odds ratio [OR] 3.70, 95% confidence interval [CI] 2.98, 4.60), hypertension (OR 1.88, 95% CI 1.55, 2.29), and black race (OR 2.25, 95% CI 1.86, 2.72) were the strongest risk factors. ACE-I use and black race were not synergistic (OR 1.10, 95% CI 0.80, 1.51). Race-ethnicity was an effect modifier for certain risk factors. Race-ethnicity acts as an effect modifier for particular angioedema risk factors. The two strongest risk factors, ACE-I use and black race, were not synergistic. 3b.

    The study objective was to generate pilot data to evaluate the effectiveness and safety of C1-esterase-inhibitor concentrate (C1-INH) compared to standard treatment in patients with angiotensin-converting enzyme inhibitor (ACEi)-induced angioedema affecting the upper aerodigestive tract. Proof-of-concept case series with historical control. Adult patients with angioedema in the upper aerodigestive tract presenting to the emergency department were included. After establishing the diagnosis of ACEi-induced angioedema based on patient history and thorough clinical examination, all patients were administered 1,000 international units (IU) of C1-INH intravenously. A historical control group consisting of adult patients with ACEi-induced angioedema who had been treated with intravenous corticosteroids and antihistamines at the same institution over the past 8 years was used for comparison. The most important parameters assessed were the time to complete resolution of symptoms and the need for intubation or tracheotomy. Ten patients were included in the C1-INH group and 47 in the corticosteroid/antihistamine group. The time to complete resolution of symptoms was considerably longer in the historical control group (33.1 ± 19.4 hours) than in the C1-INH group (10.1 ± 3.0 hours). No intubation or tracheotomy was needed in the C1-INH group (0/10 patients), whereas three out of the 47 historical controls required tracheotomy and two were intubated (5/47). The results suggest a role for C1-INH as an effective and safe therapeutic option in patients with ACEi-induced angioedema, which needs to be confirmed by further larger and double-blinded studies. 4. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    Angioedema is a potentially life-threatening adverse reaction to angiotensin-converting enzyme inhibitors and angiotensin receptor blockers. To study the genetic etiology of this rare adverse event, international consortia and multicenter recruitment of patients are needed. To reduce patient heterogeneity, we have standardized the phenotype. In brief, it comprises swelling in the head and neck region that first occurs during treatment. It should not coincide with urticaria or have another likely cause such as hereditary angioedema. PMID:24960520

    Angioedema is a rare and serious adverse drug reaction (ADR) to angiotensin-converting enzyme (ACE) inhibitor treatment. Dry cough is a common side effect of ACE inhibitors and has been identified as a possible risk factor for angioedema. We compared characteristics between patients with ACE inhibitor-induced angioedema and cough with the aim of identifying risk factors that differ between these adverse events. Data on patients with angioedema or cough induced by ACE inhibitors were collected from the Swedish database of spontaneously reported ADRs or from collaborating clinicians. Wilcoxon rank sum test, Fisher's exact test, and odds ratios (ORs) with 95% CIs were used to test for between-group differences. The significance threshold was set to P angioedema and 121 with cough only. Smoking and concomitant selective calcium channel blocker treatment were more frequent among patients with angioedema than cough: OR = 4.3, 95% CI = 2.1-8.9, P = 2.2 × 10 -5 , and OR = 3.7, 95% CI = 2.0-7.0, P = 1.7 × 10 -5 . Angioedema cases were seen more often in male patients (OR = 2.2, 95% CI = 1.4-3.6, P = 1.3 × 10 -4 ) and had longer time to onset and higher doses than those with cough ( P = 3.2 × 10 -10 and P = 2.6 × 10 -4 ). A multiple model containing the variables smoking, concurrent calcium channel blocker treatment, male sex, and time to onset accounted for 26% of the variance between the groups. Smoking, comedication with selective calcium channel blockers, male sex, and longer treatment time were associated with ACE inhibitor-induced angioedema rather than cough.

    Compartment syndrome of the upper extremity is a surgical emergency that, when left untreated, can have dire consequences. Its causes are numerous, one of which is the uncommon entity hereditary angioedema, an autosomal dominant disease resulting in edema in a variety of potential locations, including the extremities. This is only the second time hereditary angioedema has been mentioned in the literature as a cause of compartment syndrome. We present a case of hereditary angioedema leading to hand and forearm compartment syndrome in a 13-year-old pediatric patient. Diagnosis of hereditary angioedema was made by our Rheumatology colleagues with physical exam and a thorough history, and confirmed by laboratory studies. Our patient presented with compartment syndrome of the hand and forearm and underwent hand and volar forearm fasciotomies. She was subsequently worked up for hereditary angioedema with laboratory results confirming the diagnosis. She was discharged after a 5-day hospitalization with prophylactic C1-inhibitor therapy. Hereditary angioedema is a rare but known cause of compartment syndrome of the upper extremity, and must be considered when patients present with compartment syndrome of unknown etiology. This disease can be diagnosed by laboratory studies and symptoms can be controlled with medical therapy.

    Full Text Available BACKGROUND: Few studies on autoimmune hepatitis have enrolled non-Caucasian groups. AIMS: To evaluate Brazilian children with type 1 and 2 autoimmune hepatitis regarding outcome and clinical and biochemical parameters. PATIENTS AND METHODS: Thirty-six patients were submitted to a protocol that evaluated the clinical history, physical and biochemical data, and the course of the disease. Twenty-four children had type 1 autoimmune hepatitis, seven had type 2 and five had unclassified autoimmune hepatitis. Most patients were females (77%, with a median age at diagnosis of 11 years, and the median duration of symptoms was 5.5 and 8 months for types 1 and 2, respectively. Jaundice and choluria were the most common clinical manifestations. RESULTS: Treatment with azathioprine and prednisone was successful in patients with type 1 and 2 autoimmune hepatitis. AST and ALT decreased after 4 to 8 weeks of treatment compared to pretreatment levels in type 1 autoimmune hepatitis. Increased GGT values returned to pretreatment levels after 1 year in the two types. Three patients died and three other patients underwent liver transplantation. CONCLUSIONS: Non-Caucasian children had a similar disease when compared to Caucasian ones with autoimmune hepatitis. Increased levels of GGT during the first year of treatment should not be the only parameter for the indication of cholangiopathy.RACIONAL: Poucos estudos sobre hepatite autoimune têm sido conduzidos em pacientes não-caucasianos.

    Hereditary angioedema due to C1 inhibitor deficiency (C1-INH-HAE) is a rare disorder characterized by intermittent and unpredictable episodes of swelling which cause disfigurement, disability, pain, or, in case of laryngeal swelling, risk of death. Historical factors, including the intermittent nature of the disorder, the lack of awareness of this ultra-rare condition amongst medical personnel, lack of specialist centers, and limited treatment options have contributed to under-diagnosis and under-treatment of the condition. Incorrect treatment of attacks has been common, even when medical help is sought. This has lead to reduced health-seeking behavior and alternative coping strategies, sometimes even denial, in many families, while a minority of HAE-affected patients have become serial emergency room attenders with chronic pain and ongoing requirement for opiate-based painkillers. Both strategies have incurred not only physical but also psychological and economic consequences.In the last 10 years, new and effective acute therapies have been made available, some of which have also provided short-term and long-term prophylaxis options, together with a better understanding of older prophylactic drugs. Improved awareness of HAE amongst the general public, family members, and physicians has reduced the long delay in diagnosis and increased the number of patients receiving effective and up-to-date therapies to improve the physical impact of the disorder.Data on the impact of treatment on the psychological outcomes is scarce, but the limited information available suggests that access to specialist advice and treatment leads to psychological as well as physical improvement.HAE also has profound effects on individual and family economic output, directly via absenteeism from school or work and indirectly via lost opportunities. Economic improvements associated with better treatments are offset by the high cost of new acute treatments, resulting in difficult pharmaco

    2016-01-01

    Uncontrolled generation of bradykinin (BK) due to insufficient levels of protease inhibitors controlling contact phase (CP) activation, increased activity of CP proteins, and/or inadequate degradation of BK into inactive peptides increases vascular permeability via BK-receptor 2 (BKR2) and results in subcutaneous and submucosal edema formation. Hereditary and acquired angioedema due to C1-inhibitor deficiency (C1-INH-HAE and -AAE) are diseases characterized by serious and potentially fatal attacks of subcutaneous and submucosal edemas of upper airways, facial structures, abdomen, and extremities, due to inadequate control of BK generation. A decreased activity of C1-inhibitor is the hallmark of C1-INH-HAE (types 1 and 2) due to a mutation in the C1-inhibitor gene, whereas the deficiency in C1-inhibitor in C1-INH-AAE is the result of autoimmune phenomena. In HAE with normal C1-inhibitor, a significant percentage of patients have an increased activity of factor XIIa due to a FXII mutation (FXII-HAE). Treatment of C1-inhibitor-dependent angioedema focuses on restoring control of BK generation by inhibition of CP proteases by correcting the balance between CP inhibitors and BK breakdown or by inhibition of BK-mediated effects at the BKR2 on endothelial cells. This review will address the pathophysiology, clinical picture, diagnosis and available treatment in C1-inhibitor-dependent angioedema focusing on BK-release and its regulation. Key Messages Inadequate control of bradykinin formation results in the formation of characteristic subcutaneous and submucosal edemas of the skin, upper airways, facial structures, abdomen and extremities as seen in hereditary and acquired C1-inhibitor-dependent angioedema. Diagnosis of hereditary and acquired C1-inhibitor-dependent angioedema may be troublesome as illustrated by the fact that there is a significant delay in diagnosis; a certain grade of suspicion is therefore crucial for quick diagnosis.

    Full Text Available Angioedema is a rare but potentially life threatening condition commonly associated with angiotensin-converting enzyme inhibitors (ACEIs. The incidence is approximately 0.1- 0.2% and may occur within the first week to several years of taking an ACEI. We present a case of a 37-year-old African-American male who was uneventfully taking a drug combination of quinapril and hydrochlorothiazide. When his medication was changed to lisinopril he developed an acute swelling of his lower lip and chin on fifth dose. The angioedema subsided within 24 hours after discontinuation of lisinopril. Therefore, this suggests that future treatment with ACEIs, as well as angiotensin receptor blockers (ARBs, is not recommended in this type of patient.

    Episodic angioedema with eosinophilia (Gleich syndrome) is a rare disorder characterized by episodes of angioedema and eosinophilia that occur at monthly intervals and resolve spontaneously without therapy. Despite the striking periodicity of this disorder, its similarity to other cyclic hematopoietic disorders with multilineage involvement has not been assessed. To characterize the involvement of cell lineages in the etiology and pathogenesis of episodic angioedema with eosinophilia, four subjects were evaluated by blood counts and other analyses over the course of 1-2 months. Surface marker expression was assessed on T cells by flow cytometry and clonality by polymerase chain reaction. Intracellular cytokine evaluation, bone marrow and skin biopsies were performed during different parts of the cycle. Cycling of multiple cell lineages, including neutrophils, lymphocytes and eosinophils, was observed in the four subjects with the disorder with a periodicity of 25-35 days. An aberrant CD3(-)CD4(+) T-cell population was detected in all four subjects, and T-cell receptor rearrangement studies showed a clonal pattern in three subjects. A peak of type II cytokines was detected in the serum of subjects prior to the onset of symptoms and eosinophil cycling and corresponded to ex-vivo type II cytokines detected intracellularly in CD3(+)CD4(+)CD154(+) T cells. Although the etiology of episodic angioedema with eosinophilia is not yet known, multiple lineages, including lymphocytes, neutrophils and mast cells, are involved and may be related to disease pathogenesis. Whether these cells act directly or promote eosinophilia and eosinophil activation remains to be elucidated. All subjects gave informed consent and were evaluated under an Institutional Review Board-approved protocol (NCT00001406). Copyright© Ferrata Storti Foundation.

  8. The Janus faces of acquired angioedema: C1-inhibitor deficiency, lymphoproliferation and autoimmunity.

    Wu, Maddalena Alessandra; Castelli, Roberto

    2016-02-01

    Several clinical and biological features of lymphoproliferative diseases have been associated with an increased risk of developing autoimmune manifestations. Acquired deficiency of C1-inhibitor (C1-INH) (AAE) is a rare syndrome clinically similar to hereditary angioedema (HAE) characterized by local increase in vascular permeability (angioedema) of the skin and the gastrointestinal and oro-pharyngo-laryngeal mucosa. Bradykinin, a potent vasoactive peptide, released from high molecular weight kininogen when it is cleaved by plasma kallikrein (a serine protease controlled by C1-INH), is the mediator of symptoms. In total 46% of AAE patients carry an underlying hematological disorder including monoclonal gammopathy of uncertain significance (MGUS) or B cell malignancies. However, 74% of AAE patients have anti-C1-INH autoantibodies without hematological, clinical or instrumental evidence of lymphoproliferative disease. Unlike HAE patients, AAE patients usually have late-onset symptoms, do not have a family history of angioedema and present variable response to treatment due to the hypercatabolism of C1-INH. Experiments show that C1-INH and/or the classical complement pathway were consumed by the neoplastic lymphatic tissues and/or anti-C1-INH neutralizing autoantibodies. Therapy of AAE follows two directions: 1) prevention/reversal of the symptoms of angioedema; and 2) treatment of the associated disease. Different forms of B cell disorders coexist and/or evolve into each other in AAE and seem to be dominated by an altered control of B cell proliferation, thus AAE represents an example of the strict link between autoimmunity and lymphoproliferation.

    Summary Idiopathic histaminergic acquired angioedema (IH‐AAE) is a common cause of recurrent angioedema without wheals. It is a mast cell‐mediated disease thought to belong to the same clinical entity as chronic urticaria (CU). The objective of this study was to describe the clinical and epidemiological characteristics of IH‐AAE patients. From 2014 to 2015, 534 patients were seen at our national reference centre for angioedema and/or urticaria. Among them, we identified 31 patients with idiopathic histaminergic acquired angioedema without wheals (IH‐AAE). Thirty‐one patients (15 men and 16 women) with a mean age of 50 years met the criteria for IH‐AAE. The average delay in diagnosis was 6·3 years. A history of allergy was found in 12 patients (38·7%), nine suffering from allergic rhinitis. The mean duration of attacks was 28·1 h. The AE attack was located in the upper respiratory tract in 54·8% of cases (17 patients). A lingual location was found in 29% of patients. Men were more likely than women to have an upper airway involvement. No intubations or admissions to intensive care units were reported. The dosage of anti‐histamines to control the symptoms was onefold the recommended dose in 51·6% of patients (16 patients), twofold in 32% (10 patients) and three–fourfold in 16·1% (five patients). IH‐AAE is characterized by an important delay in diagnosis, a frequent involvement of the upper airway and a benign course during attacks. As in CU, a trial of up to fourfold dose of H1‐anti‐histamines may be necessary to control symptoms. PMID:26969870

    From the report of Hirschberg, only 3 years after aspirin synthesis, there have been numerous works dedicated to showing the different types of adverse reactions found following aspirin administration. However, there are few publications on the process of urticaria and/or acute angioedema induced by ASA and few reported cases were found in children. Thus, we present 6 atopic children with urticaria and/or angioedema related with ASA. A carefully detailed history, oral provocation with ASA, oral provocation with other NSAI and HBDT with ASA were done to all of them. The oral provocation with ASA was positive in 5 of the 6 cases. The provocations with the rest of the NSAI and tartrazine and sodium benzoate were negative in all of the patients. The HBDT was positive in 5 of the cases. In conclusion, we insist that aspirin intolerance is not infrequent in infancy and it is not rare to see urticaria and or angioedema, in spite of the fact that asthmatics, atopics or non atopics, usually present as bronchospasm. We also believe that the HBDT can be a method of diagnosis used in these cases.

    This study aimed to determine the duration of use, presentation, and management of angiotensin converting enzyme (ACE) inhibitor-related angioedema patients at an urban academic medical center. Retrospective chart review. Eighty-eight patients who presented with ACE inhibitor-related angioedema between January 1, 2012, and December 31, 2012, were identified. They presented anywhere from 1 day to 20 years after starting an ACE inhibitor. About half the patients (50.7%) presented after taking an ACE inhibitor for at least 1 year. Fifty-five patients were female (62.5%). Twenty-eight patients (31.8%) had an airway intervention with 27 intubated and 1 requiring cricothyroidotomy. Six patients were intubated after more than 1 flexible laryngoscopy. The percentage of patients with involvement of the face, lips, tongue, floor of mouth, soft palate/uvula, and larynx were 12.5%, 60.2%, 39.7%, 6.8%, 17.0%, and 29.5%, respectively. Sixty-eight percent of patients with laryngeal edema were intubated. The majority of patients were treated with a corticosteroid and H1 and H2 receptor antagonists. Angioedema can occur at any time after starting ACE inhibitor use, with nearly half occurring after 1 year of use. Laryngeal involvement occurred in a minority of patients, but most of these patients were felt to require airway protection. © The Author(s) 2014.

    Full Text Available A case report of fosinopril-induced angioedema of the intestine with a chronic course accompanied by multiple acute exacerbations is described. Angiotensin-converting enzyme (ACE inhibitor-induced angioedema of the intestine (AIAI occurs in a minority of patients taking an ACE inhibitor. The clinical presentation encompasses acute abdominal symptoms, pronounced bowel edema and ascites with occasional facial and/or oropharyngeal swelling. AIAI is diagnosed based on the temporal relationship between the symptomatic presentation and drug use, absence of alternative diagnoses including other causes of angioedema, and the prompt resolution of symptoms upon discontinuation of the ACE inhibitor. Prompt radiological investigation (abdominal computerized tomography and/or ultrasound is critical in making an early diagnosis and in preventing unnecessary surgical intervention. There is a female predominance of AIAI, which may reflect the interaction of estradiol with the various pathways involved in the pathophysiology of AIAI. Management of AIAI consists mainly of conservative measures and discontinuation of the ACE inhibitor. Angiotensin II receptor antagonists should not be considered as appropriate alternatives. Awareness and knowledge of AIAI are important because of the increasing use of ACE inhibitors, current delays in making the diagnosis, obvious management strategies once the diagnosis is made and the dysutility of alternative diagnoses, which may lead to considerable morbidity. AIAI must be considered in patients taking ACE inhibitors who develop gastrointestinal complaints irrespective of the duration of the therapy.

    Hereditary angioedema due to C1-inhibitor deficiency (HAE-C1-INH) is a rare, autosomal-dominant disease. HAE-C1-INH is characterized by recurrent attacks of marked, diffuse, nonpitting and nonpruritic skin swellings, painful abdominal attacks, and laryngeal edema. The extremities and the gastrointestinal tract are most commonly affected. Swelling of the upper respiratory mucosa poses the greatest risk because death from asphyxiation can result from laryngealedema. HAE-C1-INH attacks are variable, unpredictable, and may be induced by a variety of stimuli, including stress or physical trauma. Because the clinical presentation of HAE-C1-INH is similar to other types of angioedema, the condition may be a challenge to diagnose. Accurate identification of HAE-C1-INH is critical in order to avoid asphyxiation by laryngeal edema and to improve the burden of disease. Based on an understanding of the underlying pathophysiology of IHAE-C1-INH, drugs targeted specifically to the disease, such as C1-inhibitor therapy, bradykinin B2-receptor antagonists, and kallikrein-inhibitors, have become available for both treatment and prevention of angioedema attacks. This article reviews the clinical features, differential diagnosis, and current approaches to management of HAE-C1-INH.

    Tartrazine has been frequently linked to several diseases. However, a cause-and-effect role for tartrazine in these illnesses, especially in urticaria, has not always been established. The aim of this study is to determine the incidence of intolerance to tartrazine among subjects who experienced an acute episode of urticaria/angioedema following the ingestion of a meal or a product containing this substance. This was a retrospective study based on analysis of data of patients reported to have experienced episodes of urticaria and/or angioedema after ingesting meals or products containing tartrazine. At the first visit to the outpatients clinic, a careful anamnesis had been taken. Patients had then been submitted to the following diagnostic tests: IgE tests to common inhalant allergens and food allergens and a double-blind placebo-controlled challenge with tartrazine. A total of 102 subjects were enrolled in the study: 19 (18.6%) showed at least one relevant positive reaction to an IgE test for food allergy. Only one subject (1%) had reactions after ingestion of 5 mg of tartrazine, given on day 5. She did not have adverse reactions to placebo. This study shows that the percentage of acute urticaria and/or angioedema induced by tartrazine is very low (1%). In view of our results, we suggest that all physicians with patients who have suffered adverse reactions that could be attributed to tartrazine should also carefully evaluate other possible causes.

    Angiotensin-converting enzyme (ACE) inhibitor-induced angioedema is a rare, albeit serious emergency that can result in airway compromise and potentially death if not treated promptly. Currently, there are no agents approved by the Food and Drug Administration to target ACE inhibitor angioedema and to prevent intubation. C1 inhibitors are approved for hereditary angioedema but may show promise in alleviating inflammation associated with ACE inhibitor angioedema. A 41-year-old man presented to the emergency department with swelling of his lips a few days after starting lisinopril for hypertension. Despite receiving diphenhydramine, ranitidine, and methylprednisolone, the swelling progressed to the patient's tongue. A C1 inhibitor was ordered in an effort to prevent intubation. Before the arrival of the medication, the patient was intubated emergently for airway protection. After receipt of the C1 inhibitor, the swelling dramatically improved, and the patient was successfully extubated after less than 18 hours from presentation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case illustrates a potential role for C1 inhibitors in the emergency setting for treating drug-induced angioedema, which may prevent or minimize mechanical ventilation time.

    Full Text Available Objective: To elucidate the progression of angioedema of the head and neck with routine management and to assess the utility of serial physical exams and fiberoptic laryngoscopy in its management. Methods: This study was a prospective observational research. From 2013 to 2014, a prospective observational study was conducted at a tertiary referral center. Forty patient were approached, 7 refused, 33 (18–90 years old were enrolled. Patients presented with angioedema involving the head and neck over a 12 month period were asked to participate in the study. Physical examination and fiberoptic laryngoscopy were performed at presentation and then repeated at least 1 h later. Results: Thirty-three patients with head and neck angioedema from any cause were enrolled (mean age 58, range 23–89 years. The upper lip was the most commonly involved site (58%. On reevaluation, 82% of patients reported subjective improvement in symptoms. The association between subjective improvement and the physical exam, including fiberoptic laryngoscopy findings, was statistically significant (P < 0.001. Conclusion: In stable patients with angioedema of any head and neck subsite, self-reported symptoms are associated with clinical stability or improvement as assessed by physical signs and fiberoptic laryngoscopy. Patients' symptoms may be an appropriate surrogate to monitor clinical status without the need for routine serial physical examinations or fiberoptic laryngoscopy, though further study is needed.

    Background Hereditary angioedema (HAE), caused by deficiency in C1-inhibitor (C1-INH), leads to unpredictable edema of subcutaneous tissues with potentially fatal complications. As surgery can be a trigger for edema episodes, current guidelines recommend preoperative prophylaxis with C1-INH or attenuated androgens in patients with HAE undergoing surgery. However, the risk of an HAE attack in patients without prophylaxis has not been quantified. Objectives This analysis examined rates of perioperative edema in patients with HAE not receiving prophylaxis. Methods This was a retrospective analysis of records of randomly selected patients with HAE type I or II treated at the Frankfurt Comprehensive Care Centre. These were examined for information about surgical procedures and the presence of perioperative angioedema. Results A total of 331 patients were included; 247 underwent 700 invasive procedures. Of these procedures, 335 were conducted in 144 patients who had not received prophylaxis at the time of surgery. Categories representing significant numbers of procedures were abdominal (n = 113), ENT (n = 71), and gynecological (n = 58) procedures. The rate of documented angioedema without prophylaxis across all procedures was 5.7%; in 24.8% of procedures, the presence of perioperative angioedema could not be excluded, leading to a maximum potential risk of 30.5%. Predictors of perioperative angioedema could not be identified. Conclusion The risk of perioperative angioedema in patients with HAE type I or II without prophylaxis undergoing surgical procedures ranged from 5.7% to 30.5% (CI 3.5–35.7%). The unpredictability of HAE episodes supports current international treatment recommendations to consider short-term prophylaxis for all HAE patients undergoing surgery. PMID:23968383

    Angioedema is an uncommon but important cause of airway obstruction. Emergency airway management of angioedema is difficult. We seek to describe the course and outcomes of emergency airway management for severe angioedema in our institution. We performed a retrospective, observational study of all intubations for angioedema performed in an urban academic emergency department (ED) between November 2007 and June 2015. We performed a structured review of video recordings of each intubation. We identified the methods of airway management, the success of each method, and the outcomes and complications of the effort. We identified 52 patients with angioedema who were intubated in the ED; 7 were excluded because of missing videos, leaving 45 patients in the analysis. Median time from arrival to the ED to the first intubation attempt was 33 minutes (interquartile range 17 to 79 minutes). Nasotracheal intubation was the most common first method (33/45; 73%), followed by video laryngoscopy (7/45; 16%). Two patients required attempts at more invasive airway procedures (retrograde intubation and cricothyrotomy). The intubating laryngeal mask airway was used as a rescue method 5 times after failure of multiple methods, with successful oxygenation, ventilation, and intubation through the laryngeal mask airway in all 5 patients. All patients were successfully intubated. In this series of ED patients who were intubated because of angioedema, emergency physicians used a range of methods to successfully manage the airway. These observations provide key lessons for the emergency airway management of these critical patients. Copyright © 2016 American College of Emergency Physicians. Published by Elsevier Inc.

    The Angioedema Quality of Life Questionnaire (AE-QoL) has recently been developed and validated as the first specific patient-reported outcome tool to assess quality of life (QoL) impairment in recurrent angioedema patients. As of yet, its sensitivity to change and minimal clinically important difference (MCID) have not been established. Recurrent angioedema patients with chronic spontaneous urticaria or hereditary angioedema were repeatedly asked to complete the AE-QoL along with the SF-12 and other anchors for QoL impairment and disease activity during routine care visits. The sensitivity to change of AE-QoL was determined by correlating changes in its scores over time with changes in the applied anchors. In addition, the MCID was determined using anchor-based and distributional criterion-based approaches. Two hundred and seventy-eight patients contributed data sets for analysis. Baseline AE-QoL values were found to correlate well with SF-12 results as well as all other applied anchors for angioedema-related QoL impairment and disease activity. In addition, AE-QoL score changes over time correlated significantly with changes in the above anchors, thus demonstrating its sensitivity to change. The MCID of the AE-QoL total score was found to be six points. The AE-QoL is a valuable tool to assess changes of QoL impairment in recurrent angioedema patients over time, including changes due to treatment. © 2016 John Wiley & Sons A/S.

    The first classification of angioedema without wheals was recently reported and comprises different forms of the disease distinguished by aetiology, mediator of oedema and inheritance. In total, 1725 consecutive patients with angioedema without wheals were examined at our centre between 1993 and 2012. We excluded from the analysis 667 patients because of incomplete data or because angioedema was related to a specific factor. According to the new classification of angioedema, the 1058 patients included in this analysis were diagnosed with hereditary (HAE; n = 377) or acquired angioedema (AAE; n = 681). The former group included HAE with C1-inhibitor (C1-INH) deficiency (C1-INH-HAE; n = 353) and HAE with normal C1-INH levels (n = 24), of which six had a factor XII mutation (FXII-HAE) and 18 had disease of unknown origin (U-HAE). The AAE group included disease with C1-INH deficiency (C1-INH-AAE; n = 49), AAE related to angiotensin-converting enzyme inhibitor treatment (n = 183), idiopathic histaminergic (IH-AAE; n = 379) and idiopathic nonhistaminergic angioedema (InH-AAE; n = 70). We compared hereditary and AAE with uncertain aetiopathogenesis: the FXII-HAE and U-HAE groups pooled (FXII/U-HAE) versus InH-AAE. The median age at onset of FXII/U-HAE and InH-AAE was 26 and 38 years, respectively. In addition, 56% of patients with FXII/U-HAE and 81% of those with InH-AAE reported more than five attacks per year (median duration of 48 h). The location of angioedema in patients with FXII/U-HAE versus those with InH-AAE was the following: face, 70% versus 86%; tongue, oral cavity or larynx, 55% versus 68%; limbs, 70% versus 56%; and gastrointestinal mucosa, 50% versus 20%. Prophylaxis with tranexamic acid was effective in all six patients with U-HAE and in 37 of 38 with InH-AAE who were started on this treatment. Our findings in this cohort of patients with angioedema provide new information on the clinical characteristics, diagnosis and treatment of this

Participaron 223 familiares (cuidadores principales. Se desarrolló un inventario de 36 secuelas percibidas estructuradas en 6 factores: déficits cognitivos y sensoriales, cambios de personalidad, dependencia, actividad disminuida, trastornos emocionales y autoconciencia y percepción social disminuida. Los resultados mostraron que las secuelas percibidas tienen relativamente poco impacto en el malestar psicológico del familiar. Las secuelas con mayor asociación a los síntomas psicológicos fueron dependencia, asociada significativamente a sentimientos actuales de duelo, y la actividad disminuida, que se asocia a las respuestas involuntarias de estrés de aproximación y alejamiento. Estos datos contradicen la literatura que sostiene la relación causal entre secuelas percibidas y síntomas en los familiares, sugiriendo otro tipo de factores implicados.

    Hahn, Janina; Trainotti, Susanne; Hoffmann, Thomas K; Greve, Jens

    2017-05-25

    BACKGROUND Bradykinin is an underestimated mediator of angioedema. One subgroup of bradykinin induced angioedema is angioedema triggered by treatment with angiotensin converting enzyme (ACE) inhibitors. Due to its localization in the head and neck region and its unpredictable course, it is a possibly life-threatening condition. There is not an officially approved treatment for ACE inhibitor induced angioedema. CASE REPORT We present a case of an 83-year-old woman, who presented to our ENT department because of acute swelling of the tongue. On admission, there was no pharyngeal or laryngeal edema and no dyspnea. Treatment with glucocorticoids and antihistamines had no response. The patient had ramipril as regular medication, so we assumed ACE inhibitor induced angioedema and treated consequently with C1-inhibitor (human) 1,500 IU. Nevertheless, swelling was progressive and required intubation. Even after the second specific treatment with icatibant, her angioedema subsided extremely slowly. The patient also had regular treatment with saxagliptin, a dipeptidyl peptidase 4 inhibitor, so we assumed that the simultaneous inhibition of two bradykinin degrading enzymes led to a treatment-refractory course of angioedema. CONCLUSIONS General awareness for bradykinin induced angioedema due to regular medication is limited. Our case demonstrated the importance of improving awareness and knowledge about this side effect. We need a better understanding of the pathomechanism to aid in more precise clinical diagnosis. Securing the patient's airway as well as administration of an officially approved therapy is of utmost importance. As the number of patients simultaneously treated with antihypertensive and antidiabetic drugs is likely to increase, the incidence of bradykinin mediated drug induced angioedema is likely to increase as well.

    Chronic spontaneous urticaria (CSU) severely impacts quality of life (QoL), especially in patients with wheals and angioedema. Omalizumab is approved as add-on therapy for CSU patients; however, its effect on patients who are double-positive for wheals and angioedema has not been systematically studied. The primary objective was to evaluate the efficacy of omalizumab vs placebo at week 28 using the Chronic Urticaria Quality of Life (CU-Q2oL) questionnaire. Number of angioedema-burdened days, time interval between successive angioedema episodes, disease activity, angioedema-specific and overall QoL impairment were secondary objectives. X-ACT was a phase III, randomized, double-blind study conducted in 24 centres (Germany), which selectively included CSU patients with angioedema and wheals. Patients were randomized (1 : 1) to omalizumab 300 mg or placebo (every 4 weeks up to week 24) (ClinicalTrials.gov number: NCT01723072). Of the 91 patients randomized to omalizumab (n = 44) or placebo (n = 47) at baseline, 68 completed the 28-week treatment phase (omalizumab, 35; placebo, 33). Omalizumab was superior to placebo in improving CU-Q2oL scores at week 28 (P omalizumab (0.3) vs placebo (1.1). The median time to first recurrence of angioedema was 57-63 days with omalizumab and Omalizumab significantly improved angioedema-specific QoL (P omalizumab. Omalizumab was an effective treatment option for patients with moderate-to-severe CSU symptoms and angioedema unresponsive to high doses of antihistamine treatment. © 2016 John Wiley & Sons A/S.

    Active sensitization to paraphenylendiamine (PPD) and related compounds from temporary black henna tattoos has become an epidemic in the recent years. Hair dyes also include PPD like black henna tatoos which cause allergic contact dermatitis. Skin lesions of allergic contact dermatitis from PPD are mostly seen as an exudative erythema, an erythema multiforme-like eruption or a bullous contact dermatitis. We, herein, report a 27 year-old woman with an angioedema-like reaction occurring after the first exposure to hair dye who was unaware of being previously sensitized to PPD from black henna tattoo.

    Idiopathic non-histaminergic acquired angioedema (InH-AAE) is a rare disease characterized by AE resistant to antihistamines and a chronic course. We report five new cases of InH-AAE (two women and three men) with a rapid and dramatic response to the anti-immunoglobulin-E antibody omalizumab. In our literature review, we found 13 other relevant cases with a good response to this treatment. Overall, in 6 out of 18 patients, the doses of omalizumab required to prevent recurrences of attacks were higher than the licensed dose for chronic urticaria. No significant adverse effects have been reported.

    Vegetal or animal food can produce hipersensibility reactions IgE mediated of diverse intensity. We report the case of a 54 years old woman without previous allergic antecedents who after eating frozen fish had to go to Emergencies due to angioedema especially in face and oropharynx. The ENT exploration by fibroscopia descarted laryngeal edema but the patient showed initially respiratory symptoms so she was treated with SC adrenalina and then steroids during her admission. The diagnosis of alimentary alergia would be confirmed after by Allergology with cutaneous test prick type.

    Full Text Available Angioedema related to a deficiency in the C1-inhibitor protein is characterized by its lack of response to therapies including antihistamine, steroids, and epinephrine. In the case of laryngeal edema, mortality rate is approximately 30 percent. The first case of the acquired form of angioedema related to a deficiency in C1-inhibitor was published in 1972. In our paper, we present a case of an acquired form of angioedema of the oropharyngeal region secondary to the simultaneous occurrence of two causative factors: neutralization of C1-inhibitor by an autoantibody and the use of an angiotensin convertin enzyme inhibitor.

    Laboratory tests are routinely ordered to identify or rule out a cause in patients with chronic urticaria/angioedema (CUA). The results of these tests are usually within normal limits or unremarkable. To investigate the proportion of abnormal test results in patients with CUA leading to a change in management and in outcomes of care. Retrospective analysis of a random sample of adult patients with CUA from 2001-2009. Cases totaled 356: 166 with urticaria and angioedema (AE), 187 with urticaria, and 3 with only AE. Patients were predominately women (69.1%) and white (75.6%), with a mean age of 48 ± 15 years. Abnormalities were commonly seen in complete blood counts (34%) and in complete metabolic panels (9.4%). Among the 1,872 tests that were ordered, results of 319 (17%) were abnormal. Of 356 patients, 30 underwent further testing because of abnormalities in laboratory work. This represented 30 of 1,872 tests (1.60%). Only 1 patient benefited from a subsequent change in management. Laboratory testing in CUA patients referred for an Allergy and Immunology evaluation rarely lead to changes in management resulting in improved outcomes of care.

    Bradykinin-mediated angioedema (AE) is a rare disease characterised by recurrent angioedema linked to acquired (e.g. angiotensin converting enzyme inhibitor induced AE) or hereditary disorders (e.g. AE type I or II). As the clinical picture can be misleading, diagnosis of this disease is sometimes difficult. A bradykinin-mediated AE attack may be a therapeutic emergency which requires access to effective, but expensive, treatments. Their prescription must therefore be justified. No specific marker of acute bradykinin-mediated AE attacks has yet been identified to facilitate the therapeutic decision but it has been sought in many studies. This article reviews the literature on this type of biomarker, comparing candidate bradykinin-mediated AE markers to candidate markers of mast cell activation. The most interesting biomarkers are those linked to endothelial stress (VE cadherin, E-selectin, endothelin-1, von Willebrand factor and its activity) which is significantly increased during an AE attack. All these markers must now be validated by prospective studies to determine their specificity and utility in diagnosis.

    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. A direct correlation between venous thromboembolism and Miller Fisher Syndrome or Guillain-Barre Syndrome has not been previously described. CASE REPORT We report the case of a 32-year-old Hispanic male who presented with acute, severe thromboembolic disease and concurrently demonstrated characteristic clinical features of Miller Fisher Syndrome including ophthalmoplegia, ataxia, and areflexia. Past medical and family history were negative for thromboembolic disease, and subsequent hypercoagulability workup was unremarkable. During the course of hospitalization, the patient also developed angioedema. CONCLUSIONS We describe a possible association between Miller Fisher Syndrome, thromboembolic disease, and angioedema.

    Full Text Available Henriette Farkas, Lilian Varga3rd Department of Internal Medicine, Semmelweis University, Budapest, HungaryAbstract: Hereditary angioedema (HAE resulting from the deficiency of the C1 inhibitor protein is a rare disease, characterized by paroxysms of edema formation in the subcutis and in the submucosa. Edema can cause obstruction of the upper airway, which may lead to suffocation. Prompt elimination of edema is necessary to save patients from this life-threatening condition. Essentially, these edematous attacks are related to the activation of the kinin-kallikrein system and the consequent release of bradykinin. Ecallantide (known as DX-88 previously, a potent and specific inhibitor of plasma kallikrein is an innovative medicinal product. This is the only agent approved recently by the FDA for all localizations of edematous HAE attacks. Its advantages include no risk of viral contamination, high selectivity, very rapid onset of action, good tolerability, and straightforward subcutaneous administration. Owing to the risk of anaphylaxis, ecallantide should be administered by a health care professional. A postmarketing survey to improve risk-assessment and risk-minimization has been launched. The results of these studies may lead to the approval of ecallantide for self-administration.Keywords: hereditary angioedema, C1-inhibitor deficiency, treatment, bradykinin, kallikrein inhibitor, subcutaneous administration

    Hereditary angioedema is a disease which manifests itself with episodes of spontaneous edema on skin, mucosal and airway. Treatment includes acute and prophylactic approach to minimize the attacks and severity. In many parts of the world, androgen derivatives, antifibrinolytic and fresh frozen plasma are the therapies available for prophylaxis. 16 years old teenager of without history of immune decease, has in the course of 1-year repetitive episodes of painless, non-pruritic angioedema, does not respond to antihistamine therapy, corticosteroids or adrenaline; fresh frozen plasma is applied in 1 occasion exacerbating episode with severity. The diagnosis is delayed because of the unavailability of the study in the country, so it is shipped abroad confirming the deficit of C1 Inhibitor (7.1 μg/mL). Initiating prophylactic therapy with Danazol, with subsequent episodes decreased. The delay diagnosis involves considerable risk in these patients; the importance of long-term prophylactic treatment is ratified in the use of androgens, being as an available option in developing countries.

    Full Text Available As manifestações otorrinolaringológicas nas doenças reumáticas representam um desafio diagnóstico para o reumatologista, o otorrinolaringologista e o médico generalista. Comumente, sintomas otorrinolaringológicos representam um sinal inicial de uma doença assintomática ou uma desordem auto-imune não diagnosticada, que freqüentemente exige um imediato e agressivo tratamento imunossupressor. Distúrbios auditivos podem ser vistos em pacientes com lúpus eritematoso sistêmico (LES, granulomatose de Wegener (GW, policondrite recidivante (PR, poliarterite nodosa, síndrome de Cogan, síndrome de Sjögren e menos freqüentemente na síndrome de Churg-Strauss e doença de Behçet. O nariz e seios paranasais são variavelmente afetados durante o curso da GW, síndrome de Churg-Strauss, PR e sarcoidose. Ulcerações mucosas recorrentes são comuns no LES e doença de Behçet. Xerostomia é uma manifestação comum da síndrome de Sjögren primária e secundária; aumento da glândula salivar pode ser visto nesses pacientes, assim como nos pacientes com sarcoidose. A articulação cricoaritenóide pode ser envolvida durante o curso da artrite reumatóide, espondilite anquilosante e gota; alterações osteoartríticas também têm sido descritas. Disfunção do nervo trigeminal pode ocorrer em pacientes com síndrome de Sjögren, esclerose sistêmica, LES e doença mista do tecido conjuntivo.

    Full Text Available Objetivos: revisar dados de literatura concernentes aos fatores que conferem suscetibilidade à patogenia auto-imune do diabetes mellitus tipo 1. Fonte de dados: revisão de artigos especializados no assunto publicados em bancos de dados nacionais e internacionais (SCIELO, LILACS e PUBMED. Síntese de dados: a etiopatogenia do diabetes mellitus tipo 1 está associada a fatores inflamatórios, genéticos e ambientais. Nesta revisão, abordamos o papel da auto-imunidade humoral e celular que culmina com a disfunção das células-beta produtoras de insulina. A precocidade da presença de alguns autoanticorpos como anti-ilhotas pancreáticas, antiinsulina e anti-ácido glutâmico descarboxilase é uma característica importante nesta patologia. Os diversos fatores genéticos associados ao deflagramento do diabetes mellitus tipo 1, sobretudo os associados ao sistema de antígenos leucocitários humanos, acabam por potencializar a apresentação de antígenos das ilhotas para o sistema imune. Por fim, fatores ambientais como exposição viral também contribuem para a quebra de tolerância imunológica observada nesses pacientes. Conclusões: o diabetes mellitus tipo 1 é uma entidade de etiopatogenia altamente complexa. Diversos fatores genéticos e ambientais potencializam os mecanismos de auto-imunidade humoral e celular que levam à insulite. O risco de hipoglicemia severa observada com o tratamento insulínico e as complicações crônicas do diabetes mellitus tipo 1 justificam pesquisas contínuas em relação à etiopatogenia desta entidade, o que contribuirá para abordagens terapêuticas mais eficazes.

    Renin-angiotensin-aldosterone system (RAS) blockers are commonly used for cardiovascular diseases. Currently, little information exists for the Asian population on angioedema, a rare yet serious adverse event. This study aimed to describe characteristics of RAS blockers-associated angioedema (RASBA) in Thai patients. A retrospective study using the national pharmacovigilance database of Thailand was undertaken. Cases indicating the presence of angioedema with RAS blockers uses from 1984-2011 were identified. Patient demographics, co-morbidities, concomitant drugs, information for the RAS blockers and angioedema were obtained as well as causality assessment and quality of reports. A total of 895 cases were identified. Mean age was 59.9+12.8 years and 66.5% being female. Most angioedema events (48.6%) occurred during the first week of treatment. Angiotensin converting enzyme inhibitors (87.7%) were the most commonly implicated agents followed by angiotensin receptor blockers (10.5%), aldosterone antagonist (2.1%) and direct renin inhibitor (0.2%). Out of the 895 cases incorporated in this study, 165 (18.4%) were classified as serious events and resulted in hospitalization. The overall case fatality rate was 0.4%. Respiratory disturbance occurred in 46 cases (5.1%). Patients with respiratory complications tended to be younger (53.4+13.9 vs 60.3+12.7 years old; p=0.002) and with higher frequency of allergy history (26.1% vs 14.7%; p=0.032) compared to those without respiratory complications. Based on multivariate logistic regression, the adjusted OR for history of allergy was 2.23 (95%CI: 1.04 - 4.78, p = 0.041). RASBA in Thai population occurred mostly in elderly female patients and often led to hospitalization. Since large number of patients is regularly exposed to RAS-blockers, a nationwide attempt to raise awareness of clinicians when prescribing RAS-blockers is prudent.

A LLC é diagnosticada em até 15% dos pacientes com AHAI, e em cerca de 50% dos pacientes com AHAI secundária a doença maligna. A PTI ocorre em 2%, e a APSV em 1% dos pacientes com LLC. Prednisona é o tratamento inicial de escolha para a citopenia imune associada à LLC. Para cerca de 60% dos pacientes que apresentam recidiva da manifestação auto-imune tem sido utilizada esplenectomia, imunoglobulina endovenosa, ou ciclosporina. Embora as evidências sobre fisiopatologia sejam limitadas, os mecanismos fisiopatológicos da auto-imunidade na LLC estão relacionados à atividade dos linfócitos B leucêmicos que atuam como células apresentadoras de antígeno aberrantes, e são eficientes em processar e apresentar proteínas da membrana de hemácias e de plaquetas às células TH auto-reativas. Linfócitos TH específicos para certos auto-antígenos podem escapar de mecanismos de controle de auto-tolerância, e, se ativados, podem causar doença auto-imune. O diagnóstico de AHAI contra-indica o uso de fludarabina em pacientes com LLC, pois esse análogo da purina tem sido associado ao desenvolvimento de AHAI grave e fatal, com risco consideravelmente mais alto para pacientes mais imunossuprimidos devido a vários tratamentos anteriores.Chronic lymphocytic leukemia (CLL is frequently associated with autoimmune diseases directed against hematopoietic cells, including autoimmune hemolytic anemia (AIHA, immune thrombocytopenic purpura (ITP, pure red cell aplasia (PRCA, and immune neutropenia.

    Full Text Available A tireoidite crônica auto-imune é, atualmente, a principal causa de hipotireoidismo e seu diagnóstico baseia-se nas manifestações clínico-laboratoriais. O marcador laboratorial mais importante é a presença de anticorpos antitireoglobulina e antiperoxidase, sendo este último o teste mais sensível. A biópsia aspirativa apresenta alta sensibilidade e especificidade, porém, é um método invasivo e, por isso, reservado para quando há presença de nódulo ou bócio de crescimento rápido. A cintilografia é desnecessária para o diagnóstico, já que apresenta baixa sensibilidade e especificidade. A ultra-sonografia, tanto ao modo B como ao dúplex-Doppler colorido, evoluiu de forma muito rápida e tornou-se um método simples, não-invasivo, reprodutível e com alta sensibilidade para o diagnóstico da tireoidite crônica auto-imune. Ao modo B, a ecogenicidade é um parâmetro de extrema importância, já que, além de apresentar alta correlação com o quadro citopatológico, também apresenta alta sensibilidade para o diagnóstico da tireoidite crônica auto-imune. Embora este parâmetro não seja específico da tireoidite crônica auto-imune, pois também pode estar presente na doença de Graves, na tireoidite pós-parto e na tireoidite subaguda, tais desordens podem ser facilmente diferenciadas tanto pelo quadro clínico-laboratorial quanto pelo dúplex-Doppler colorido. Assim, este artigo tem o objetivo de revisar a importância do estudo da ecogenicidade no diagnóstico da tireoidite crônica auto-imune.Chronic autoimmune thyroiditis is currently considered as the main cause for hypothyroidism and its diagnosis is based on clinical manifestations and laboratory tests results.

    Full Text Available A 50-year-old man was admitted to our emergency department due to new episode of palpitation. He had history of angioplasty of right coronary artery (RCA with drug eluting stent 2 years ago. His electrocardiogram revealed atrial fibrillation (AF. Intravenous amiodarone 150 mg during 10 minutes and then 1 mg/min infusion were started to achieve rate control and pharmacologic conversion to sinus rhythm. After 60 minutes of starting amiodarone infusion, he developed swelling of the skin around his mouth and eyes, and also mucosa of the mouth, eyes and tongue. To conclude, angioedema should be considered a rare side effect of amiodarone which is used broadly in cardiovascular field.

  19. C1 Inhibitor Deficiency and Angioedema of the Small Intestine Masquerading as Crohn’s Disease

    Full Text Available A case of C1 inhibitor deficiency presenting as localized edema of the small intestine is described. A 16-year-old, previously healthy woman presented with recurrent attacks of abdominal pain and vomiting following minor abdominal trauma. Investigations including computed tomography scan and barium studies confirmed localized edema of the jejunum. At laparoscopy, Crohn’s disease was suspected; however, a subsequent enteroscopy was normal. Complement levels revealed a low C4 level, and C1 inhibitor deficiency was later confirmed. Attacks of abdominal pain began after starting oral contraceptives and have not returned since stopping the birth control pill. This rare cause of abdominal pain is examined, and C1 inhibitor deficiency and angioedema are reviewed.

    2017-01-01

    BACKGROUND: Patients with hereditary angioedema (HAE) due to C1-inhibitor deficiency (C1-INH-HAE) experience recurrent attacks of cutaneous or submucosal edema that may be frequent and severe; prophylactic treatments can be prescribed to prevent attacks. However, despite the use of long......-term prophylaxis (LTP), breakthrough attacks are known to occur. We used data from the Icatibant Outcome Survey (IOS) to evaluate the characteristics of breakthrough attacks and the effectiveness of icatibant as a treatment option. METHODS: Data on LTP use, attacks, and treatments were recorded. Attack...... characteristics, treatment characteristics, and outcomes (time to treatment, time to resolution, and duration of attack) were compared for attacks that occurred with versus without LTP. RESULTS: Data on 3228 icatibant-treated attacks from 448 patients with C1-INH-HAE were analyzed; 30.1% of attacks occurred while...

    The severe life-threatening characteristics of hereditary angioedema (HAE) with C1-inhibitor deficiency (C1-INH-HAE) can affect anxiety levels among pediatric patients. This emotional burden together with the physical restrictions of C1-INH-HAE may decrease children's health-related quality of life (HRQoL). (i) To compare anxiety state and trait between children with C1-INH-HAE and healthy controls; (ii) to examine the relationship between the level of anxiety of children with C1-INH-HAE, their disease activity/affected sites and their HRQoL; and (iii) to predict the HRQoL of children with C1-INH-HAE based on their anxiety level and disease activity/affected sites METHODS: Thirty-three children with C1-INH-HAE (aged 5-18 years) and 52 healthy controls were recruited from Israel and Hungary. All children completed the State-Trait Anxiety Inventory for Children (STAIC), the Pediatric Quality of Life Inventory (Peds-QL) demographic questionnaire and a disease activity and site questionnaire . Disease activity was defined as the number of attacks in last year. Both anxiety state and trait were significantly higher among children with C1-INH-HAE as compared to the controls (44.74±10.56 vs 38.76±10.67, Panxiety state (F 56,2 =4.69, P=.001) and trait (F 56,2 =9.06, Panxiety trait was correlated with the number of angioedema-affected sites (r=.52, P=.003). The presence of HAE attacks and higher anxiety trait predicted a lower HRQoL in children with C1-INH-HAE. C1-INH-HAE children have higher anxiety trait and state, which correlate with reduced HRQoL domains. © 2017 EAACI and John Wiley and Sons A/S. Published by John Wiley and Sons Ltd.

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most frequent medicaments involved in drug hypersensitivity reactions, with NSAID-induced urticaria/angioedema (NIUA) being the most frequent clinical entity. The natural evolution of NIUA has been suggested to lead to chronic urticaria (CU) in an important proportion of patients, such that NIUA may therefore precede CU. Our aim was to verify whether these entities are related by following up a large cohort of patients with NIUA as well as a control group over a long period of time. The study comprised three groups: (i) patients with a confirmed history of NIUA (more than two episodes with at least two different NSAIDs or positive drug provocation tests), (ii) patients with more than two episodes of urticaria/angioedema to a single NSAID with good tolerance to a strong COX-1 inhibitor and/or evidence by in vivo tests supporting specific IgE antibodies to the drug (single NSAID-induced urticaria/angioedema, SNIUA), and (iii) controls who tolerated NSAIDs. All cases in the three groups were followed up over a period of 12 years. There were 190 patients with NIUA (64.6% female; mean age 43.71 ± 15.82 years, 110 with SNIUA, and 152 controls. At the 12-year evaluation, 12 patients with NIUA (6.15%) had developed CU over a 1- to 8-year period. Similar proportions were seen in SNIUA and controls. Nonsteroidal anti-inflammatory drugs-induced urticaria/angioedema does not seem to precede the onset of CU over the medium term. Further research including a longer follow-up is necessary to verify this observation. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Bradykinin-mediated angioedema (AE) is a rare side effect of some medications, including angiotensin converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB). In France, side-effects to treatments are reported to the national pharmacovigilance database. The national MedDRA database was searched using the term "angioedema". Patients were included if they met the clinical criteria corresponding to bradykinin-mediated AE, if their C1-inhibitor levels were normal, and if they were treated with an ACEi or an ARB. 7998 cases of AE were reported between 1994 and 2013. Among these, 112 met the criteria for bradykinin-mediated AE with normal C1-inhibitor levels. On the 112 drug-AE, patients were treated with an ARB in 21% of cases (24 patients), or an ACEi in 77% of cases (88 patients), in combination with another treatment in 17 cases (mTORi for 3 patients, iDPP-4 for 1 patient, hormonal treatment for 7 patients). ENT involvement was reported in 90% of cases (tongue: 48.2%, larynx: 23.2%). The median duration of treatment before the first attack was 720 days, and the mean duration of attacks was 36.6 h. Forty-one percent (19/46) of patients relapsed after discontinuing treatment. Angioedema triggered by medication blocking the renin/angiotensin system is rare but potentially severe, with a high risk of recurrence despite cessation of the causative drug.

    Full Text Available Acquired angioedema due to C1 inhibitor deficiency (C1INH-AAE is a rare and potentially fatal syndrome of bradykinin-mediated angioedema characterized by episodes of angioedema without urticaria. It typically manifests with nonpitting edema of the skin and edema in the gastrointestinal (GI tract mucosa or upper airway. Edema of the upper airway and tongue may lead to life-threatening asphyxiation. C1INH-AAE is typically under-diagnosed because of its rarity and its propensity to mimic more common abdominal conditions and allergic reactions. In this article, we present the case of a 62-year-old male with a history of recently diagnosed chronic lymphocytic leukemia (CLL who presented to our hospital with recurrent abdominal pain, initially suspected to have Clostridium difficile colitis and diverticulitis. He received a final diagnosis of acquired angioedema due to C1 esterase inhibitor deficiency due to concomitant symptoms of lip swelling, cutaneous nonpitting edema of his lower extremities, and complement level deficiencies. He received acute treatment with C1 esterase replacement and icatibant and was maintained on C1 esterase infusions. He also underwent chemotherapy for his underlying CLL and did not experience further recurrence of his angioedema.

    Nonsteroidal anti-inflammatory drug (NSAID)-induced urticarial and angioedema reactions are among the most commonly encountered drug hypersensitivity reactions in clinical practice. Three major clinical phenotypes of NSAID-induced acute skin reactions manifesting with angioedema, urticaria, or both have been distinguished: NSAID-exacerbated cutaneous disease, nonsteroidal anti-inflammatory drug-induced urticaria/angioedema (NIUA), and single NSAID-induced urticaria and angioedema. In some patients clinical history alone might be sufficient to establish the diagnosis of a specific type of NSAID hypersensitivity, whereas in other cases oral provocation challenges are necessary to confirm the diagnosis. Moreover, classification of the type of cutaneous reaction is critical for proper management. For example, in patients with single NSAID-induced reactions, chemically nonrelated COX-1 inhibitors can be safely used. However, there is cross-reactivity between the NSAIDs in patients with NSAID-exacerbated cutaneous disease and NIUA, and thus only use of selective COX-2 inhibitors can replace the culprit drug if the chronic treatment is necessary, although aspirin desensitization will allow for chronic treatment with NSAIDs in some patients with NIUA. In this review we present a practical clinical approach to the patient with NSAID-induced urticaria and angioedema. Copyright © 2015 American Academy of Allergy, Asthma & Immunology.

    Acquired angioedema is a rare but recognized manifestation of lymphoproliferative disorders due to deficiency in C1 esterase inhibitor. Normal level of C1 esterase inhibitor proteins in association with angioedema due to lymphoproliferative disease is a rare and an uncommon finding caused by antibodies produced from the underlying disease. Antibodies cause inactivation of C1 esterase inhibitor, thus resulting in C1 esterase inhibitor dysfunction despite of normal quantity of C1 esterase inhibitor. A 50-year-old Sri Lankan male presented with first episode of angioedema without any family history. Physical examination revealed mild pallor with swelling of tongue, lips and perioral region. On investigations, erythrocyte sedimentation rate was persistently high and bone marrow with immunohistochemistry revealed infiltration with B-cell type low grade non-Hodgkin lymphoma. Computed tomography scan of the chest and abdomen showed paratracheal and subcarinal lymphadenopathy and splenomegaly, with the findings being compatible with lymphoma. He had normal C1 esterase inhibitor protein level with reduced activity and low C1q, C4 levels indicating antibodies against C1 esterase inhibitor causing dysfunctional C1 esterase inhibitor. Adult onset angioedema should prompt physicians to suspect underlying lymphoproliferative disorder despite of C1 esterase inhibitor protein level being normal. Though uncommon, presence of antibodies against C1 esterase inhibitor secondary to lymphoproliferative disorder should be considered in the presence of normal C1 esterase inhibitor protein levels with low functional capacity in the background of acquired angioedema.

    Full Text Available Sudden sensorineural hearing loss (SSNHL is one of the autoimmune diseases of the inner ear (AIED, which is characterized by a hearing loss of above 30 decibels in at least three contiguous audiometric frequencies over a time course of 72 hours or shorter. Its cause can be found in only 10% to 15% of patients. Histopathologic findings have reported retrograde neuronal degeneration and atrophy of Corti's organ and of the vascular stria. This paper describes a case of a middle-aged female patient undergoing a treatment for hyperthyroidism who developed bilateral SSNHL. The patient was treated with methylprednilisone (1mg/kg/day for three days with considerable hearing improvement. This treatment was followed by lung and kidney tuberculosis. The immune mechanism of this entity and the possibility of interconnected participation of the antigen type, of an autoimmune disease and of bacterial infection are discussed.A surdez neurosensorial aguda (SNSA é uma das doenças auto-imunes do ouvido interno caracterizada pela perda da audição acima de 30 decibéis, em pelo menos 3 freqüências audiométricas contíguas, no período máximo de 3 dias.

    Full Text Available As doenças reumatológicas autoimunes, na maioria das vezes, possuem uma via genética comum para a autoimunidade. Vários genes foram associados com as doenças reumatológicas, para tanto iremos analisar somente alguns genes nos quais há várias evidências da existência de associação com risco ou proteção de doença autoimune. O fator de transcrição nuclear kappa B (NF-kappa B, o qual regula as respostas imunes e inflamatórias, está associado com esclerose sistêmica (ES, artrite reumatoide (AR e lúpus eritematoso sistêmico (LES, assim como os genes CXCR2 e CXCL8. Já a interleucina 10 (IL-10, que é uma citocina anti-inflamatória, está associada com quase todas as doenças reumatológicas. Neste artigo, revisamos os potenciais papéis desses genes no sistema imunológico e em diversas doenças reumatológicas. Com relação à IL-10, diversos estudos foram realizados, porém em sua maioria contraditórios - alguns encontraram ausência de associação e outros encontraram associação em diferentes polimorfismos do genes. Já em relação ao NF-kappa B, somente foi estudado em AR e LES, e não foram observadas análises significativas relevantes. Os polimorfismos genéticos do gene CXCR2 foram associados com ES, mas não estão associados com AR e LES. Já os polimorfismos genéticos do gene CXCL8 não estão associados com ES, mas estão associados com AR.

    Orolingual angioedema (OA) is a rare clinical complication with a potentially fatal risk that occurs after the intravenous application of alteplase (rt-PA) in patients with acute ischemic stroke. The purpose of this work is to investigate the related factors of OA in patients with acute ischemic stroke after the administration of intravenous thrombolytic therapy, to improve the predictive ability of OA during intravenous thrombolytic therapy, and to reduce the prevalence of complications. We recruited 1223 cases of patients with acute ischemic stroke that were treated in the Department of Neurology No. 4 of the Tianjin Huanhu Hospital from June 2014 to April 2015. The clinical manifestations of rt-PA related OA were recorded, the clinical prevalence was counted, related factors of OA after intravenous thrombolytic therapy were analyzed, and the risk assessment of rt-PA related OA was conducted. 14 cases of patients developed OA, with a prevalence rate of 1.14%. Among them, 5 had a history of urticaria, 4 of drug allergy, and 3 of food allergy. Among the 14 cases of patients, 10 developed OA in the process of intravenous thrombolysis and 4 after intravenous thrombolysis, 12 showed lip edema, 9 showed extensive swelling of tongue, 3 showed swelling of lateral tongue, 3 were complicated by respiratory distress, 10 showed infarction in the middle cerebral artery territory, and 6 had previously been given oral ACEI drugs. Orolingual angioedema is a rare complication that occurs after rt-PA intravenous thrombolytic therapy; when serious, it may endanger a patient's life. If patients take an oral hypotension such as ACEI drugs before the onset of OA, they have a history of allergies, or the lesion is an infraction in the dominated area of the middle cerebral artery, the risk of OA after rt-PA intravenous thrombolytic therapy will be increased. The prevalence of OA should be monitored during the rt-PA intravenous thrombolytic therapy process; timely detection and early

    To estimate health status utility (preference) weights for hereditary angioedema (HAE) during an attack and between attacks using data from the Hereditary Angioedema Burden of Illness Study in Europe (HAE-BOIS-Europe) survey. Utility measures quantitatively describe the net impact of a condition on a patient's life; a score of 0.0 reflects death and 1.0 reflects full health. The HAE-BOIS-Europe was a cross-sectional survey conducted in Spain, Germany, and Denmark to assess the real-world experience of HAE from the patient perspective. Survey items that overlapped conceptually with the EuroQol 5-Dimensions (EQ-5D) domains (pain/discomfort, mobility, self-care, usual activities, and anxiety/depression) were manually crosswalked to the corresponding UK population-based EQ-5D utility weights. EQ-5D utilities were computed for each respondent in the HAE-BOIS-Europe survey for acute attacks and between attacks. Overall, a total of 111 HAE-BOIS-Europe participants completed all selected survey items and thus allowed for computation of EQ-5D-based utilities. The mean utilities for an HAE attack and between attacks were 0.44 and 0.72, respectively. Utilities for an acute attack were dependent on the severity of pain of the last attack (0.61 for no pain or mild pain, 0.47 for moderate pain, and 0.08 for severe pain). There were no significant differences across countries. Mean utilities derived from the study approach compare sensibly with other disease states for both acute attacks and between attacks. The impacts of HAE translate into substantial health status disutilities associated with acute attacks as well as between attacks, documenting that the detrimental effects of HAE are meaningful from the patient perspective. Results were consistent across countries with regard to pain severity and in comparison to similar disease states. The results can be used to raise awareness of HAE as a serious disease with wide-ranging personal and social impacts.

    Omalizumab is a monoclonal antibody against IgE, nowadays approved for the treatment of persistent severe (EU) or moderate-to severe (USA) IgE-mediated asthma but there is also some evidence (case reports and four published clinical trials) on the effectiveness of this medication in urticaria and angioedema. The case of a 42-year-old woman suffering from severe allergic asthma and severe chronic urticaria with concomitant angioedema is presented in the article. She had a life-threatening episode of bronchospasm and larynx edema after exposure to house dust recorded in her medical history. The patient did not respond to standard therapy. The improvement in asthma control and remission of chronic urticaria and angioedema was achieved after introducing the therapy with omalizumab.

    2016-07-01

    Full Text Available Contrast induced angioedema is a rapidly progressive state involving a number of organ systems including the upper airway tract; which is usually a type I anaphylactic reaction also known as immediate hypersensitivity reaction. Prompt preservation of the respiratory tract is the cornerstone of this situation. The use of fiberoptic bronchoscope for tracheal intubation though very helpful, has some special considerations due to the anatomic distortions created by edema.This manuscript describes a patient with contrast induced angioedema managed successfully. Serum levels of IgE were highly increased during the first hours after the event; while serum levels of complement were normal. However, rapid airway management and prophylactic intubation saved the patient and prevented the possible aftermath of airway obstruction.Keywords: airway management; type I anaphylactic reaction, angioedema; fiberoptic bronchoscope.Conflict of interest: none of the authors has any conflict of interest.

    Full Text Available O tratamento das lesões gengivais de doenças vesicobolhosas auto-imunes constitui grande desafio na estomatologia, principalmente pela natureza crônica das lesões. O tratamento sistêmico é necessário no controle das apresentações mais graves; entretanto, quando possível, o tratamento tópico é preferível. Este artigo descreve uma técnica oclusiva para aplicação de corticosteróide tópico que tem demonstrado ser eficaz no controle dessas lesões, sobretudo em pacientes com manifestações exclusivamente gengivais.Management of gingival lesions of vesicobullous autoimmune diseases is one the main challenges to oral medicine, primarily because of their chronic nature. Systemic therapy is required in most severe lesions, however, whenever feasible, topic corticosteroid therapy is preferred. This article describes a technique to provide topical occlusive corticotherapy that has shown to be effective in controlling these lesions, especially in patients exclusively with gingival lesions.

    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. Hyperelastic constitutive modeling is used by generalizing the standard anisotropic, incompressible soft tissue framework to incorporate the swelling effect. Finite element stress analysis then proceeds with swelling of the mucous layer providing the driving factor for the mechanical analysis. The amount of airway constriction is governed by the mechanical interaction between the three predominant tissue types. The detailed stress analysis indicates the presence of stress concentrations near the various tissue junctions. Because of the tissue's nonlinear mechanical behavior, this can lead to material stiffness fluctuations as a function of location on the trachea. Patient specific modeling is presented. The role of the modeling in the interpretation of diagnostic procedures and the assessment of therapies is discussed. Copyright © 2017 John Wiley & Sons, Ltd.

    We evaluated the efficacy and safety of icatibant self-administration in 15 patients with hereditary angioedema (HAE) types I or III, for 55 acute attacks (mostly severe or very severe). Icatibant self-administration was generally effective: first symptom improvement occurred in 5 min–2 h (HAE type I; n = 17) and 8 min–1 h (HAE type III; n = 9) for abdominal attacks and 5–30 min (HAE type I; n = 4) and 10 min–12 h (HAE type III; n = 6) for laryngeal attacks. Complete symptom resolution occurred in 15 min–19 h (HAE type I; n = 8) and 15 min–48 h (HAE type III; n = 9) for abdominal attacks and 5–48 h (HAE type I; n = 3) and 8–48 h (HAE type III; n = 5) for laryngeal attacks. No patient required emergency hospitalization. The only adverse events were mild, spontaneously resolving injection site reactions. Patients reported that carrying icatibant with them gave them greater confidence in managing their condition. PMID:22519593

    Hereditary angioedema type III (HAEIII) is a rare inherited swelling disorder that is associated with point mutations in the gene encoding the plasma protease factor XII (FXII). Here, we demonstrate that HAEIII-associated mutant FXII, derived either from HAEIII patients or recombinantly produced, is defective in mucin-type Thr309-linked glycosylation. Loss of glycosylation led to increased contact-mediated autoactivation of zymogen FXII, resulting in excessive activation of the bradykinin-forming kallikrein-kinin pathway. In contrast, both FXII-driven coagulation and the ability of C1-esterase inhibitor to bind and inhibit activated FXII were not affected by the mutation. Intravital laser-scanning microscopy revealed that, compared with control animals, both F12–/– mice reconstituted with recombinant mutant forms of FXII and humanized HAEIII mouse models with inducible liver-specific expression of Thr309Lys-mutated FXII exhibited increased contact-driven microvascular leakage. An FXII-neutralizing antibody abolished bradykinin generation in HAEIII patient plasma and blunted edema in HAEIII mice. Together, the results of this study characterize the mechanism of HAEIII and establish FXII inhibition as a potential therapeutic strategy to interfere with excessive vascular leakage in HAEIII and potentially alleviate edema due to other causes.

  2. Hereditary angioedema as a metabolic liver disorder: novel therapeutic options and prospects for cure

    Full Text Available Hereditary angioedema (HAE is a rare autosomal dominant disorder caused by mutations of the SERPING1 or the Factor 12 genes. It is potentially fatal, particularly if not identified at an early stage. Apart from androgens, which are contraindicated in children and in pregnant women, a range of effective, albeit very expensive treatments have recently become available for HAE patients. The cost of these new treatments is beyond the reach of most developing countries. At this time, there is no cure for the disorder. In spite of mutations of the SERPING1 gene, autoimmunity and infections are not prominent features of the condition. Here we present the argument that HAE should be viewed primarily as a metabolic liver disorder. This conceptual paradigm shift will stimulate basic research and may facilitate new therapeutic approaches to HAE outlined in this paper. We suggest several novel potential treatment options for HAE from the perspectives of clinical immunology, molecular biology and liver transplantation. Many of these offer the prospect of curing the disorder. The effectiveness of these options are rapidly improving in many cases and their risks are decreasing. Given the very high costs of treating HAE, some of these curative options may become feasible in the next decade.

    Hereditary angioedema (HAE) is a very rare disease that occurs in about 1 in 50,000 to 150,000 people. HAE is caused by low levels or inproper function of the plasma protein C1 inhibitor (C1-INH) which regulates activation of the complement system and the coagulation system. The typical symptom of HAE is regional swellings without pain nor itching, usually triggered by physical trauma or emotional stress. Unlike allergic edema, HAE attacks do not respond to antihistamines, corticosteroids noradrenaline. The swelling attacks against face and throat are potentially life-threatening, and should be treated as a medical emergency. We report a patient with HAE who underwent radical cystectomy of the upper gum under general anesthesia. Because the oral surgery with tracheal intubation is known to be a risk factor of laryngeal edema in a patient with HAE, she was given C1-INH before operation to prevent laryngeal edema according to HAE Guideline 2010 by the Japanese Association for Complement Research. Her pharynx and larynx were checked with Airwayscope before intubation and with bronchofiberscope before extubation, but no edema was recognized. Postoperatively, she was given C1-INH on the next morning again. She was discharged seven days after operation without any complications.

    Full Text Available RESUMEN: Este estudio evaluó la utilidad de un programa de rehabilitación cognitiva y funcional de memoria para pacientes con daño cerebral adquirido. Diez participantes con deterioro cognitivo leve o moderado participaron en el estudio, cinco de ellos asistieron durante cuatro meses a un programa semanal de rehabilitación, mientras que los otros cinco no recibieron intervención neuropsicológica. Los resultados mostraron que el grupo de rehabilitación mejoró la puntuación en la Escala de Memoria de Wechsler III. De igual forma, se encontró que la puntuación en la escala de fallos de memoria de la vida diaria solo mejoró en el grupo que recibió rehabilitación. Los resultados sugieren que el programa de rehabilitación de la memoria resulta útil en el tratamiento de las secuelas tanto cognitivas como funcionales resultantes del daño cerebral adquirido. ABSTRACT: This study evaluated the usefulness of a cognitive and functional rehabilitation of memory program for patients with acquired brain injury. Ten participants with mild- to -moderate cognitive impairment participated in the study; five of them for four months attended a weekly rehabilitation program, while the other five did not receive any neuropsychological intervention. The results showed that the rehabilitation group improved the score in the Wechsler III Memory Scale. Similarly, it was found that the score on the memory scale of failure of the daily life only improved in the group that received rehabilitation. The results suggest that memory rehabilitation program is useful in the treatment of both cognitive and functional sequels resulting from acquired brain damage.

    Health-related quality of life (HR-QoL) is impaired in patients with hereditary angioedema (HAE) but has not yet been satisfactorily described. To study HR-QoL in patients with HAE by combining different HR-QoL instruments with disease activity assessment. All adults in the Swedish HAE registry were invited to take part in this questionnaire study, which used the generic HR-QoL instruments, EuroQol 5 Dimensions 5 Level (EQ-5D-5L) and the RAND Corporation Short Form 36 (RAND-36), the disease-specific Angioedema Quality of Life instrument (AE-QoL), the recently introduced Angioedema Activity Score (AAS) form, and questionnaires on sick leave and prophylactic medication. Sixty-four of 133 adults (26 men, 38 women) between 18 and 91 years old responded. The most affected HR-QoL dimensions in the EQ-5D-5L were pain/discomfort and anxiety/depression; in the RAND-36, energy/fatigue, general health, pain; and, in the AE-QoL, fears/shame and fatigue/mood. Women had lower HR-QoL in the RAND-36 for general health and energy/fatigue (p 0 had significantly impaired HR-QoL. There were significant associations (p depression, and fatigue/mood are important aspects of HAE but the AE-QoL disregards pain. HR-QoL was not significantly affected by prophylaxis. Increased disease activity was associated with impaired HR-QoL, which justifies more active disease management.

    The use of angiotensin-converting enzyme inhibitors (ACEI) has been associated with the development of bradykinin-mediated angioedema. With ever-widening indications for ACEI in diseases including hypertension, congestive heart failure and diabetic nephropathy, a concomitant increase in ACEI-Angioedema (ACEI-A) has been reported. At present there is no validated severity scoring or discharge criteria for ACEI-A. We sought to develop and validate an investigator rating scale with corresponding discharge criteria using clinicians experienced in treating ACEI-A. In-depth, 60-min qualitative telephone interviews were conducted with 12 US-based emergency physicians. Beforehand, clinicians were sent four case studies describing patients experiencing different severities of angioedema attacks. Clinicians were initially asked open-ended questions about their experience of patients' symptoms, treatment and discharge decisions. Clinicians then rated each patient case study and discussed patient diagnoses, ratings of symptom severity and discharge evaluation. The ratings were used to assess inter-rater reliability of the scale using the intra-class correlation coefficient (ICC) using IBM SPSS analysis Version 19 software. The findings provide support focusing on four key symptoms of airway compromise scored on a 0-4 scale: 1) Difficulty Breathing, 2) Difficulty Swallowing, 3) Voice Changes and 4) Tongue Swelling and the corresponding discharge criteria of a score of 0 or 'No symptoms' for Difficulty Breathing and Difficulty Swallowing and a score of 0 or 1 indicating mild or absence of symptoms for Voice Change and Tongue Swelling. Eleven clinicians agreed the absence of standardized discharge criteria supported the use of this scale. All physicians concurred with the recommended discharge criteria. The clinician ratings provided evidence of strong inter-rater reliability for the rating scale (ICC > 0.80). The investigator rating scale and discharge criteria are

    Abstract Introduction The clinical characteristics and icatibant‐treatment outcomes of patients with hereditary angioedema with normal C1 inhibitor (HAE‐nC1 INH) are limited. Methods We retrospectively analyzed data from French HAE patients enrolled in the Icatibant Outcome Survey registry (from July 2009 to September 2013) to compare disease characteristics and the effectiveness and safety of acute icatibant‐treated angioedema attacks in patients with HAE‐nC1 INH, HAE with C1 INH deficiency (type I), or dysfunction (type II). Results One center in Grenoble contributed 22 patients with HAE‐nC1 INH and a family history of HAE while 15 centers across France contributed 153 patients with HAE type I and seven patients with HAE type II. Patients with HAE‐nC1 INH compared to HAE type I, respectively, were more likely to be female (88.1% vs. 63.4%), older at median age of disease onset (21 years vs. 15 years), and have a greater rate of abdominal (80% vs. 61%) and laryngeal (23% vs. 14%) attacks. Icatibant was effective in both groups though the median time to resolution of attack was significantly longer in the HAE‐nC1 INH group (20.0 h, 37 attacks) versus the HAE type I group (14.0 h, 67 attacks). Icatibant was self‐administered for 96.1% of attacks in patients with HAE‐nC1 INH and 75.8% in patients with HAE type I. No serious adverse side effects related to icatibant were reported. Conclusions These data help further define the disease characteristics of HAE‐nC1 INH in the French population and extend the limited data reporting the safe and effective use of icatibant in acute treatment of angioedema in French patients diagnosed with HAE‐nC1 INH.

    Background Hereditary angioedema (HAE) is a rare genetic disease causing unpredictable and potentially life-threatening subcutaneous and submucosal edematous attacks. Cinryze® (Shire ViroPharma Inc., Lexington, MA, USA), a nanofiltered C1 inhibitor (C1-INH), is approved in Europe for the treatment, preprocedure prevention, and routine prophylaxis of HAE attacks, and for the routine prophylaxis of attacks in the USA. This phase 3 study assessed the safety and efficacy of 2 C1-INH doses in preventing attacks in children aged 6–11 years. Methods A randomized single-blind crossover study was initiated in March 2014. Results for the first 6 patients completing the study are reported here. After a 12-week qualifying observation period, patients were randomly assigned to 1 of 2 C1-INH doses, 500 or 1,000 U, every 3–4 days for 12 weeks and crossed over to the alternative dose for a second 12-week period. The primary efficacy endpoint was the number of angioedema attacks per month. Results Six females with HAE type I and a median age of 10.5 years received 2 doses of C1-INH (500 and 1,000 U). The mean (SD) difference in the number of monthly angioedema attacks between the baseline observation period and the treatment period was −1.89 (1.31) with 500 U and −1.89 (1.11) with 1,000 U. During the treatment periods, cumulative attack severity, cumulative daily severity, and the number of attacks needing acute treatment were lower. No serious adverse events or study drug discontinuations occurred. Conclusions Interim findings from this study indicate that routine prevention with intravenous administration of C1-INH is efficacious, safe, and well tolerated in children ≥6 years of age.

    Angioedema is an infrequent complication of the use of angiotensin-converting enzyme inhibitors (ACEi) that has an incidence of up to 0.5%. The oropharynx is most commonly affected. Angioedema of the small bowel is a much rarer occurrence; it uniformly presents with abdominal pain of variable duration. A 51-year-old man presented to the emergency department (ED) with generalized abdominal pain, emesis, diarrhea, and bloating. Medical history was significant for hypertension and medications included captopril, metoprolol and aspirin. Vital signs and laboratory tests were unremarkable. Due to the presence of significant abdominal tenderness with guarding on examination, a FAST (focused assessment with ultrasound in trauma) examination was performed and revealed free fluid in the abdomen. A computed tomography scan of the abdomen was quickly obtained, which revealed a large amount of simple-appearing free fluid within the abdomen and mucosal edema throughout the small bowel. The patient underwent an emergent diagnostic laparoscopy and was ultimately diagnosed with angioedema of the small bowel, deemed secondary to captopril usage. Captopril was discontinued and symptoms gradually resolved with supportive care. When imaging is obtained in cases such as this one, small bowel submucosal edema and ascites are often present. Supportive care and cessation of ACEi usage are the cornerstones of treatment. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: In patients on ACEi, it is important to keep this diagnosis in mind to potentially avoid an unneeded surgical intervention, as the condition is self-limiting and can be treated primarily with supportive measures.

    Full Text Available We report a case of acute facial oedema in an elderly hospitalized patient which was initially misdiagnosed as angioedema secondary to antibiotics in a patient with an allergic diathesis. We describe the differential aetiologies and then the true cause of the oedema, which was an uncommon complication of a very common condition in the elderly: a pneumomediastinum with subcutaneous emphysema probably due to rupture of an emphysematous lung bulla during chronic obstructive pulmonary disease (COPD exacerbation. Lastly, we focus on the therapeutic procedures instituted for the treatment of the pneumomediastinum.

    Full Text Available Autoimmunity is characterized by tissue destruction that implicates functional damages caused by self-reactive cells that escape self-tolerance mechanisms. Autoimmune diseases can be initiated by viral infections and the study of the association between these viruses and autoimmunity has advanced the understanding of the molecular mechanisms involved in autoimmune diseases. The Human T-Cell Lymphotropic Virus Type I (HTLV-1 is a deltavirus that infects preferentially lymphocytes. Retrovirus particles like has been identified in patients with autoimmune diseases. Therefore this review had by objective approach the main aspects involving HTLV-1 with systemic lupus erythematosus and rheumatoid arthritis. Studies show that retroviruses can integrate their genetic material in host DNA, changing the expression gene profile related with apoptosis and immunologic system molecules. It’s known that HTLV-1 can cause different clinical manifestations in their careers and the mechanisms that triggers the HTLV-1 associated autoimmune diseases are not well known. Besides the perpetuation and marked production of pro-inflammatory cytokines, studies have demonstrated that both Th17 cells and T regulatory cells (Tregs are involved in autoimmune diseases pathogenesis. Therefore the HTLV-1 viral particles recognized could be used as a risk marker in the development of autoimmune diseases.A autoimunidade é caracterizada pela destruição tecidual, que acarreta danos funcionais, causados por células autoreativas que escapam dos mecanismos de autotolerância.

    The purpose of this study was to assess the impact of age and sex on the reporting of cough and angioedema related to renin-angiotensin system (RAS) inhibitors. A case/noncase study was performed in VigiBase. Two case groups were identified, reports of cough and reports of angioedema, and noncases were all reports of all other adverse events. Logistic regression analysis was used to assess the association between reporting of cough and angioedema with each class of RAS inhibitors stratified by age/sex and to control for confounding. The reporting of cough with angiotensin-converting enzyme (ACE) inhibitors was significantly higher in women than in men [adjusted reporting odds ratio (ROR): 44.0, 95% CI (43.2-44.8) for women vs. 29.2, 95% CI (28.5-29.9) for men]. There was no difference in reporting of cough linked to angiotensin receptor blockers (ARBs) and aliskiren between men and women. In contrast, the reporting of angioedema with ACE inhibitors and ARBs was significantly higher in men than in women, but for aliskiren, women had a significantly higher ROR than men [adjusted ROR: 5.20, 95% CI (4.18-6.46) for women vs. 3.04, 95% CI (2.30-4.02) for men]. The reporting of cough with ACE inhibitors was increased with age until reaching a plateau at middle adulthood (40-59 years) and the reporting of angioedema with ACE inhibitors was increased with age until elderly (60-79 years). Age had only a slight effect on the reporting of cough and angioedema with ARBs and aliskiren. Both age and sex have substantial effects on the reporting of cough and angioedema with RAS inhibitors and in particular ACE inhibitors. Further study is needed to determine whether these differences mainly express different adverse drug reaction risks in subgroups or also can be explained by factors influencing reporting. © 2017 The Authors.

    Hereditary angioedema (HAE) is a rare but potentially life-threatening disease marked by spontaneous, recurrent attacks of swelling. The broad range of consequences of HAE on patients' lives is not well understood. The study objective was to comprehensively characterize the burden of illness and impact of HAE types I and II from the patient perspective. The HAE Burden of Illness Study in Europe was conducted in Spain, Germany, and Denmark to assess the real-world experience of HAE from the patient perspective via a one-time survey, which included items on clinical characteristics and physical and emotional impacts. One hundred eighty-six patients participated; 59% reported having an attack at least once a month, 67% reported moderate-to-severe pain during their last attack, and 74% reported moderate-to-severe swelling. The most common sites of the last attack were the abdomen and extremities; 24% experienced an attack in more than one site. The impact of HAE on daily activities was high during attacks and did not vary significantly by body site affected; patients also reported that HAE impacted their daily activities between attacks. Patients reported substantial anxiety about future attacks, traveling, and passing HAE to their children. Based on Hospital Anxiety and Depression Scale scores, 38 and 14% had clinically meaningful anxiety and depression, respectively. Despite standard of care, HAE patients still have frequent and painful attacks. Patients experience substantial impairment physically and emotionally both during and between attacks. A better understanding of these effects may help in the clinical management of HAE patients.

    Early therapy of hereditary angioedema (HAE) decreases morbidity, improves outcomes, decreases absenteeism, and possibly decreases mortality. This can be accomplished best with self-therapy. Previously, the authors examined barriers to self-therapy from the perspective of the nurse and the physician, but data are lacking on what patients perceive as major barriers to self-administered therapy for HAE. To identify those barriers in a prospective fashion by patient interview. After approval from the institutional review board, a telephone survey was performed of patients with HAE from a database of patients who were recently seen in the clinic. The survey focused on anxiety, depression, stress, concerns regarding method of administration, the ability to inject themselves, and what they perceived as barriers to providing self-care. Ninety-two patients were contacted and 59 agreed to participate. With 69% of those patients currently undergoing self-administered treatment, the results showed minimal depression and anxiety, a high satisfaction with treatment, and significant compliance with treatment. Most of those not yet on self-administered therapy wanted to start despite being satisfied with the care received in the emergency department. They also believed care at home would be optimal. The main concern of the 2 groups was not being able to treat themselves in the event of an HAE attack. From these data, it is obvious that most patients are willing to self-treat. This suggests that physicians should encourage self-treatment of HAE to improve outcomes and quality of life of patients with HAE. Copyright © 2015 American College of Allergy, Asthma & Immunology.

    Recombinant human C1-inhibitor (rhC1INH) purified from milk of transgenic rabbits is used for the treatment of acute attacks in patients with hereditary angioedema (HAE) due to C1-inhibitor (C1INH) deficiency. The objective was to investigate the risk of rhC1INH inducing IgE antibodies or eliciting anaphylactic reactions. In subjects treated with rhC1INH, we retrospectively analysed the frequency and clinical relevance of pre-exposure and potentially newly induced IgE antibodies against rabbit and other animal allergens including cow's milk by the ImmunoCAP(®) Specific IgE blood test system. 130 HAE patients and 14 healthy subjects received 300 administrations of rhC1INH, 65 subjects (47.4 %) on one occasion; 72 (52.6 %) on at least two occasions (range 2-12; median 2). Five subjects had pre-existing anti-rabbit epithelium IgE; the subject with the highest levels and a previously undisclosed rabbit allergy developed an anaphylactic reaction upon first exposure to rhC1INH, whereas the other four subjects with lower pre-existing IgE levels (Class 1-3), did not. No other anaphylactic reactions were identified in any of the subjects exposed to rhC1INH. Analysis of post-exposure samples revealed that the risk of inducing new or boosting existing IgE responses to rabbit or cow's milk allergens was negligible. The propensity of rhC1INH to induce IgE antibodies following repeated administration of rhC1INH is low. Subjects with substantially elevated anti-rabbit epithelium IgE antibodies and/or clinical allergy to rabbits may have an increased risk for an allergic reaction. No other risk factors for allergic reactions to rhC1INH have been identified.

    To characterize the pharmacokinetics (PK) of recombinant human C1 inhibitor (rhC1INH) in healthy volunteers and hereditary angioedema (HAE) patients. Plasma levels of C1INH following 294 administrations of rhC1INH in 133 subjects were fitted using nonlinear mixed-effects modelling. The model was used to simulate maximal C1INH levels for the proposed dosing scheme. A one-compartment model with Michaelis-Menten elimination kinetics described the data. Baseline C1INH levels were 0.901 [95% confidence interval (CI): 0.839-0.968] and 0.176 U ml(-1) (95% CI: 0.154-0.200) in healthy volunteers and HAE patients, respectively. The volume of distribution of rhC1INH was 2.86 l (95% CI: 2.68-3.03). The maximal rate of elimination and the concentration corresponding to half this maximal rate were 1.63 U ml(-1) h(-1) (95% CI: 1.41-1.88) and 1.60 U ml(-1) (95% CI: 1.14-2.24), respectively, for healthy volunteers and symptomatic HAE patients. The maximal elimination rate was 36% lower in asymptomatic HAE patients. Peak C1INH levels did not change upon repeated administration of rhC1INH. Bodyweight was found to be an important predictor of the volume of distribution. Simulations of the proposed dosing scheme predicted peak C1INH concentrations above the lower level of the normal range (0.7 U ml(-1)) for at least 94% of all patients. The population PK model for C1INH supports a dosing scheme on a 50 U kg(-1) basis up to 84 kg, with a fixed dose of 4200 U above 84 kg. The PK of rhC1INH following repeat administration are consistent with the PK following the first administration. © 2013 The British Pharmacological Society.

    Full Text Available Hereditary angioedema (HAE is a potentially life-threatening disease caused by mutations in the gene encoding the serine protease inhibitor (serpin C1 inhibitor (C1-inh. The mutations cause decreased functional plasma levels of C1-inh, which triggers unpredictable recurrent edema attacks. Subjects suffering from HAE have been classified in type I patients with decreased functional and antigenic levels of C1-inh, and type II patients with decreased functional but normal antigenic C1-inh levels. However, a few reports have demonstrated that some mutations cause C1-inh polymerization in vitro, and it is speculated that C1-inh polymers may exist in patient plasma, challenging the current classification of HAE patients. To investigate the presence of C1-inh polymers in patient plasma samples, we developed an immunological method, where monoclonal antibodies produced against polymerized C1-inh were applied in native PAGE western blotting. Using this approach we analyzed genuine plasma samples from 31 Danish HAE families, and found that plasma samples from three genotypically distinct HAE type I families (classified upon C1-inh plasma concentrations contained C1-inh polymers. Identical C1-inh polymerization phenotypes were observed in four affected family members from one of these families. Genotyping of the families revealed that the polymerogenic mutations of two families were located in proximity to the reactive center loop insertion site in C1-inh (p.Ile271Thr and p.Ser258_Pro260del,and one mutation affected helix C (p.Thr167Asn. In conclusion, we demonstrate that C1-inh polymers are present in the plasma of a subgroup of HAE type I patients.

    In view of the large heterogeneity in the clinical presentation of hereditary angioedema due to C1 inhibitor deficiency (C1-INH-HAE), great efforts are being made towards detecting measurable biological determinants of disease severity that can help to improve the management of the disease. Considering the central role that plasma kallikrein plays in bradykinin production, we investigated the contribution of the functional polymorphism KLKB1-428G/A to the disease phenotype. We studied 249 C1-INH-HAE patients from 114 European families, and we explored possible associations of C1-INH-HAE clinical features with carriage of KLKB1-428G/A, combined or not with that of the functional F12-46C/T polymorphism. Carriers of the G allele of the KLKB1-428G/A polymorphism exhibited a significantly delayed disease onset (i.e., by 4.1 years [p < 0.001], depending on the zygocity status), while carriers of both the KLKB1-428G/A and the F12-46C/T polymorphism displayed an 8.8-year delay in disease onset (p < 0.001) and a 64% lower probability of needing long-term prophylactic treatment (p = 0.019). These findings support our initial hypothesis that functional alterations in genes of proteins involved in bradykinin metabolism and function affect the clinical phenotype and possibly contribute to the pathogenesis of C1-INH-HAE. Given that an earlier onset of symptoms is inversely correlated with the subsequent course of the disease and, eventually, the need for long-term prophylaxis, these polymorphisms may be helpful prognostic biomarkers of disease severity. © 2017 S.

    Background Angioedema without wheals (AE) is a symptom characterised by localised episodes of oedema presumably caused by kinin release from kininogen cleavage. It can result from a hereditary deficiency in C1 Inhibitor (C1Inh), but it can present with normal level of C1Inh. These forms are typically difficult to diagnose although enhanced kinin production is suspected or demonstrated in some cases. Objectives We wanted to investigate bradykinin overproduction in all AE condition with normal C1Inh, excluding cases with enhanced kinin catabolism, and to propose this parameter as a disease biomarker. Methods We retrospectively investigated high molecular weight kininogen (HK) cleavage pattern, using gel electrophoresis and immunorevelation. Plasma samples were drawn using the same standardised procedure from blood donors or AE patients with normal C1Inh conditions, normal kinin catabolism, and without prophylaxis. Results Circulating native HK plasma concentrations were similar in the healthy men (interquartile range: 98–175μg/mL, n = 51) and in healthy women (90–176μg/mL, n = 74), while HK cleavage was lower (p14.4% HK cleavage for men; 33.0% HK cleavage for women, with >98% specificity achieved for all parameters. In plasma from patients undergoing recovery two months after oestrogen/progestin combination withdrawal (n = 13) or two weeks after AE attack (n = 2), HK cleavage was not fully restored, suggesting its use as a post-attack assay. Conclusion As a diagnostic tool, HK cleavage can offer physicians supportive arguments for kinin production in suspected AE cases and improve patient follow-up in clinical trials or prophylactic management.

    Full Text Available Abstract Background Hereditary Angioedema (HAE is a rare, autosomal dominant (AD disorder caused by a C1 esterase inhibitor (C1-inh deficiency or qualitative defect. Treatment of HAE in many parts of the world fall short and certain items need to be addressed in future guidelines. Objective To identify those individuals who should be on long-term prophylaxis for HAE. Additionally, to determine if prodromal symptoms are sensitive and specific enough to start treatment with C-1 INH and possibly other newly approved therapies. Also, to discuss who is appropriate to self-administer medications at home and to discuss training of such patients. Methods A literature review (PubMed and Google was performed and articles published in peer-reviewed journals, which addressed HAE prophylaxis, current HAE treatments, prodromal symptoms of HAE and self-administration of injected home medications were selected, reviewed and summarized. Results Individuals whom have a significant decrease in QOL or have frequent or severe attacks and who fail or are intolerant to androgens should be considered for long-term prophylaxis with C1INH. Prodromal symptoms are sensitive, but non-specific, and precede acute HAE attacks in the majority of patients. Although the treatment of prodromal symptoms could lead to occasional overtreatment, it could be a viable option for those patients able to adequately predict their attacks. Finally, self-administration, has been shown to be feasible, safe and effective for patients who require IV therapy for multiple other diseases to include, but not limited to, hemophilia. Conclusions Prophylactic therapy, treatment at the time of prodromal symptoms and self-administration at home all should allow a reduction in morbidity and mortality associated with HAE.

    Angioedema (AE) is a condition that may prompt a visit to an emergency department (ED), and can quickly progress to airway obstruction. To optimize treatment of AE, it is necessary to understand epidemiology and practice patterns. This study measured the magnitude of AE ED visits and characterized demographics, management, frequency of airway interventions, and mortality. Analysis of two national data sets. From the Nationwide Emergency Department Sample and National Hospital Ambulatory Medical Care Survey, we identified all patients presenting from 2006 to 2010 with a primary diagnosis of AE, characterized by the International Classification of Diseases, Ninth Edition, Clinical Modification code 995.1. The discharges were weighted and stratified by comorbidities, age, treatments, and region. χ 2 , t test, and linear regression were employed for comparisons. Total discharges increased from 87,481 (29.3 of 100,000 people) to 111,116 (35.8 of 100,000 people). More females were afflicted (57%), and 41.1% were African American. The majority (83%) of patients were discharged from the ED. Twelve percent of cases were attributed to antihypertensive adverse reaction, and these patients were older (P < .0001, odds ratio [OR] = 1.02), and had more comorbidities (P < .0001, OR = 5.66), hospital admissions (P < .0001, OR = 4.83), and intubations (P < .03, OR = 2.07). Overall, patients required intubation infrequently (<1%) and mortality was low (0.08%). The AE burden on EDs has increased over time. Patients with adverse reactions to antihypertensives are older, have more comorbidities, and require admission and intubation more frequently. Further investigation is needed to better delineate causation and outcome predictors, and to understand regional practice variance. 2c.

    Acute treatment of hereditary angioedema due to C1 inhibitor deficiency has become available in the last 10 years and has greatly improved patients’ quality of life. Two plasma-derived C1 inhibitors (Berinert and Cinryze), a recombinant C1 inhibitor (Ruconest/Conestat alpha), a kallikrein inhibitor (Ecallantide), and a bradykinin B2 receptor inhibitor (Icatibant) are all effective. Durably good response is maintained over repeated treatments and several years. All currently available prophylactic agents are associated with breakthrough attacks, therefore an acute treatment plan is essential for every patient. Experience has shown that higher doses of C1 inhibitor than previously recommended may be desirable, although only recombinant C1 inhibitor has been subject to full dose–response evaluation. Treatment of early symptoms of an attack, with any licensed therapy, results in milder symptoms, more rapid resolution and shorter duration of attack, compared with later treatment. All therapies have been shown to be well-tolerated, with low risk of serious adverse events. Plasma-derived C1 inhibitors have a reassuring safety record regarding lack of transmission of virus or other infection. Thrombosis has been reported in association with plasma-derived C1 inhibitor in some case series. Ruconest was associated with anaphylaxis in a single rabbit-allergic volunteer, but no further anaphylaxis has been reported in those not allergic to rabbits despite, in a few cases, prior IgE sensitization to rabbit or milk protein. Icatibant is associated with high incidence of local reactions but not with systemic effects. Ecallantide may cause anaphylactoid reactions and is given under supervision. For children and pregnant women, plasma-derived C1 inhibitor has the best evidence of safety and currently remains first-line treatment. PMID:29594115

    Full Text Available The benefits of the worldwide approval of new drugs for the treatment of acute C1-INH-HAE attacks may still not reach all patients. Identifying the current barriers in the access to medication, as well as conducting a detailed assessment of the progress in this area, is essential to achieve universal treatment. Two hundred and twenty five patients registered in the Argentina Hereditary Angioedema Patient Association (AHAEPA were randomly selected and invited to participate in a web based questionnaire on accessibility to icatibant and pdC1-INH, self-treatment, delay to treatment, and coverage. The data retrieved was compared to our previous reports in 2008 and 2013. We collected 156/225 answers. One hundred and eighteen (76% patients have either pdC1-INH (n = 86, icatibant (n = 10 or both (n = 22, while 38 (24% do not have access to treatment. In 2008, 26% had access while 82% had it in 2013. Thirty-two subjects (22% self-inject themselves, similar to 29% in 2013, even though between studies, widespread self-injection training activities have taken place. However, considering injections by proxy, home treatment reached 56%. Only half of the patients decide to receive treatment early during the attack. Ninety-nine patients (63% have full coverage, thirty (19% have no coverage at all and the rest only obtain partial reimbursement. Twenty-nine families (31% share a single treatment dose of the medication, better than 36% in 2013. Argentina's C1-INH-HAE patients had a sustained improvement in their access to medication. Efforts should continue to further improve accessibility and optimal management of HAE acute attacks to all patients in the country.

    Full Text Available Huamin Henry Li Institute for Asthma and Allergy, Chevy Chase, MD, USA Abstract: Hereditary angioedema (HAE is a rare genetic disease characterized by episodic subcutaneous or submucosal swelling. The primary cause for the most common form of HAE is a deficiency in functional C1 esterase inhibitor (C1-INH. The swelling caused by HAE can be painful, disfiguring, and life-threatening. It reduces daily function and compromises the quality of life of affected individuals and their caregivers. Among different treatment strategies, replacement with C1-INH concentrates is employed for on-demand treatment of acute attacks and long-term prophylaxis. Three human plasma-derived C1-INH preparations are approved for HAE treatment in the US, the European Union, or both regions: Cinryze®, Berinert®, and Cetor®; however, only Cinryze is approved for long-term prophylaxis. Postmarketing studies have shown that home therapy (self-administered or administered by a caregiver is a convenient and safe option preferred by many HAE patients. In this review, we summarize the role of self-administered plasma-derived C1-INH concentrate therapy with Cinryze at home in the prophylaxis of HAE.

    Active chronic urticaria, identified as a mast cell- and basophil-dependent inflammatory disorder of the skin is able to elicit acute phase response (APR). However, systemic inflammatory response in different types of urticaria is poorly characterized. To determine APR pattern in a clearly defined group of patients with acute urticaria and/or angioedema - induced by NSAIDs. Plasma IL-6 and serum C-reactive protein (CRP) concentrations were studied in 17 patients with NSAIDs-induced acute urticaria/angioedema (NSAIDsAU) and in 20 healthy controls. Eleven patients who used NSAIDs were presented at the emergency room with acute urticaria/angioedema while the remaining six manifested the symptoms during the aspirin challenge test. Patients were examined in a dynamic manner: during the acute phase, and next, after subsidence of the symptoms. CRP and IL-6 concentrations increased significantly in patients with NSAIDsAU as compared with their asymptomatic period and the healthy subjects. In addition, NSAIDsAU patients showed elevated concentration of the biomarkers following aspirin provocation with the baseline values recovered in the asymptomatic period. These results indicate that an acute systemic inflammatory response is activated in patients with NSAIDs-induced urticaria and/or angioedema. The study supports the evidence proving that up-regulation of CRP and IL-6 in urticaria/angioedema does not necessarily reflect any concomitant infection or other inflammatory processes, but may be due to the disease itself. © 2012 The Authors.

    Hereditary angioedema due to C1 inhibitor deficiency (C1-INH-HAE) may affect health-related quality of life (HRQoL). A specific HRQoL questionnaire for adult patients with C1-INH-HAE, the HAE-QoL, has recently been developed in Spain. The objective of this study was to perform a cross-cultural validation and psychometric study of the HAE-QoL in an international setting. Cross-cultural adaptation of the Spanish HAE-QoL draft version and an international rating phase with experts were performed. The resultant version of the HAE-QoL, a clinical questionnaire, and Short Form 36-item Health Survey Version 2.0 (SF-36v2) were pilot tested internationally. Item reduction was based on both descriptive and exploratory factor analysis. Psychometric properties were assessed. Cross-cultural adaptation of the HAE-QoL was performed in 18 countries. The draft version of the HAE-QoL was pilot tested in 332 patients, and accurate data were obtained from 290 patients from 11 countries. The reduction process resulted in a new version with 25 items and 7 dimensions (treatment difficulties, physical functioning and health, disease-related stigma, emotional role and social functioning, concern about offspring, perceived control over illness, and mental health). Strong psychometric properties were observed (Cronbach's α 0.92; test-retest reliability 0.87). Convergent validity showed mild to moderate correlations with SF-36v2 physical and mental component summaries (0.45 and 0.64, respectively) and with SF-36v2 dimensions (P < .004). HAE-QoL scores discriminated significantly among severity groups (median: asymptomatic 133.5 vs severe 84.0; P < .001); between patients with and without long-term prophylaxis (median: 101 vs 90; P = .001); and between patients with and without psychiatric and/or psychological care (median: 74 vs 103; P ≤ .001). The HAE-QoL, currently available in 18 languages, showed good reliability and validity evidence. Copyright © 2016 American Academy of Allergy

As células NK fazem parte da imunidade inata e através de seus receptores KIR identificam células-alvo que apresentam moléculas HLA (Human Leukocyte Antigen modificadas ou diferentes, induzindo à sua lise. Os receptores KIR são resultados da expressão dos genes KIR (19q13.14 na membrana celular das células NK, os quais são polimórficos e formam haplótipos. A diversidade de frequência dos haplótipos KIR em certas populações sugere que alguns indivíduos apresentam diferentes níveis de proteção contra algumas doenças e o balanço entre inibição e ativação celular mediada pelos receptores KIR e seus ligantes faz com que a célula NK possa auxiliar o organismo na vigilância imunológica. Além disso, há várias evidências da existência de associação de genótipos KIR ativadores com risco aumentado de doença autoimuneKiller Immunoglobulin-like Receptor (KIR genes express as receptors that activate or inhibit Natural Killer (NK cells. The NK cells are part of the innate immune response and, through their KIR receptors, they identify target cells that have modified or different HLA (Human Leukocyte Antigen molecules, inducing their lysis. The KIR receptors result from the expression of KIR genes (19q13.14 on the cell membrane of NK cells, which are polymorphic, and form haplotypes. The diversity of the frequency of KIR haplotypes in certain populations suggests that some individuals have different levels of protection against some diseases. The balance between cell inhibition and activation enables the NK cell to help the organism in immunological surveillance. In addition, there is evidence of the association of activating KIR genotypes with an increased risk for autoimmune disease

    Full Text Available Cold agglutinin disease (CAD with autoimmune haemolytic anemia is characterized by the production of harmful cold autoantibodies associated with increased red cell destruction during exposure to cold. The treatment of CAD is very difficult and a great effort is required to obtain therapeutic success. Cyclophosphamide is a potent immunosuppressive agent which is widely used in all bone marrow transplantation conditioning regimens for patients with acquired severe aplastic anemia. In this report, we describe the case of a coronary artery disease patient with severe CAD, but without lymphoproliferative disease, in which general measures and immunosuppressive therapies were adopted, there by avoiding blood transfusions.A doença por aglutininas a frio (CAD cursando com anemia hemolítica auto-imune (AHAI é decorrente da produção de autoanticorpos que reagem muito bem a baixas temperaturas, dirigidos contra hemácias autólogas. A habilidade desses anticorpos em destruir as hemácias encontra-se diretamente relacionada à sua capacidade em fixar complemento durante a exposição do paciente a baixas temperaturas. A AHAI por anticorpos frios pode ser idiopática - ausência de doença de base - ou secundária, geralmente associada a desordens linfoproliferativas de células B ou determinados processos infecciosos. A hemólise é intravascular, através de aglutininas da classe IgM, com teste direto da antiglobulina humana positivo para complemento. O tratamento da CAD é difícil, exigindo um esforço contínuo, necessário para se obter sucesso terapêutico. A ciclofosfamida é um agente imunossupressor potente, amplamente utilizado em transplantes de medula óssea, particularmente nos portadores de anemia aplástica. Descrevemos o caso de um coronariopata portador de CAD severa, cuja exploração diagnóstica excluiu doença linfoproliferativa. Adotamos medidas gerais de suporte e terapia imunossupressora, coibindo o uso de hemotransfusões.

    To evaluate the place in therapy of fresh frozen plasma (FFP), C1 esterase concentrate (C1-INH), ecallantide, and icatibant in the management of angiotensin-converting enzyme inhibitor-induced angioedema (ACEI-IA). A literature search was performed using PubMed (1946 through August 2015) and Embase (angioedema, another bradykinin-mediated event, may be effective for use in ACEI-IA. Positive efficacy results were reported with FFP and C1-INH while mixed results have been seen with ecallantide. Off-label icatibant has the most evidence supporting its use in ACEI-IA with rapid symptom resolution (10 minutes to 6 hours) and avoidance of intubation and tracheotomy in several cases. These agents were well-tolerated in ACEI-IA. ACEI-IA is typically a self-limiting event. First-line therapies include ACEI discontinuation, observation, and supportive medications (eg, corticosteroids, antihistamines, and epinephrine). Symptom progression can be life-threatening and may require interventions such as tracheotomy and intubation. Off-label use of FFP and medications approved for hereditary angioedema have resulted in rapid resolution of symptoms and avoidance of intubation. Among these agents, icatibant has the most supporting evidence and has been incorporated into practice guidelines and algorithms as a second-line agent for serious life-threatening ACE-IA. © The Author(s) 2015.

    Full Text Available Chronic urticaria is a common condition characterized by recurrent hives lasting several weeks or months and is usually idiopathic. Approximately half of the individuals with chronic urticaria will present with episodes of angioedema that can be severe and debilitating. In this report, we describe a 47-year-old Hispanic male who presented initially for an evaluation of chronic hives following hospitalization due to hive-induced anaphylaxis. The individual had a history significant for urticaria and angioedema beginning in his early 30s. Interestingly, both the individual’s 41-year-old sister and 12-year-old daughter were also affected with chronic urticaria and severe angioedema. Whole exome sequencing of the proband and several family members revealed a heterozygous variant of uncertain significance in exon 2 of TNFAIP3, denoted as c.65G>A (p.R22Q, in all affected members. Variants in TNFAIP3 have been associated with multiple autoimmune diseases, susceptibility to allergy and asthma, and periodic fever syndromes, suggesting that this variant could potentially play a role in disease.

    Full Text Available O hipotireoidismo primário adquirido é uma endocrinopatia frequentemente diagnosticada na espécie canina. A terapia consiste na suplementação oral com levotiroxina sódica (L-tiroxina, no entanto vários protocolos terapêuticos têm sido propostos pela literatura, com doses variando 11 a 44µg/kg uma a duas vezes ao dia, visto à grande variabilidade de absorção e meia-vida plasmática do fármaco. Foram estudados 30 cães com hipotiroidismo primário adquirido (13 machos e 17 fêmeas, idade média de 7,9±1,9 anos e peso médio de 19,1±12,6 kg atendidos no Hospital Veterinário da Universidade Guarulhos (UnG e no Serviço de Endocrinologia de duas clínicas particulares da cidade de São Paulo (2009-2011, com o objetivo de avaliar a posologia e a frequência de administração da L-tiroxina, mais frequentemente utilizada, capaz de garantir um controle terapêutico satisfatório, avaliado através dos sinais clínicos e do teste pós-tiroxina, além de correlacionar a dose de tiroxina empregada com o peso dos animais. A dose média de tiroxina utilizada em nossa casuística foi de 16,9±3,1µg/kg, sendo a frequência de administração a cada 12 horas em 50% dos casos. Para se investigar uma possível correlação entre o peso e a dosagem de tiroxina utilizada, uma vez que cães de pequeno porte apresentam maior taxa metabólica que cães de grande porte, os animais foram agrupados em grupo A, cães com peso 10 kg (n=18/30, 26,8±10,7 kg. A dose média de tiroxina empregada nos grupos A e B não apresentaram diferença estatística e foram, respectivamente, 16±3µg/kg e 17±3µg/kg. A frequência de administração foi 50% a cada 24 horas e 50% a cada 12 horas para ambos os grupos. Dessa forma, a dose de tiroxina não parece se correlacionar com o peso do animal, sendo imprevisível quem deverá receber dose e frequência máxima da medicação. O protocolo deve ser individualizado e o paciente devidamente monitorado.

    Full Text Available In spite of the steady increase in the incidence of Staphylococcus aureus infections, it remains a relatively uncommon cause of meningitis. To our knowledge, no series of community-acquired S. aureus meningitis (CASAM restricted to children has been published. So far in this retrospective study we report our experience with CASAM in children, hospitalized from 1983 to 1998 at Nossa Senhora da Glória Children's Hospital (HINSG. During the sixteen-year study period, 2,319 new cases of acute pyogenic meningitis were diagnosed at HINSG. Community-acquired S. aureus was identified as the causative agent in 30 patients (1.3 percent. The predominantly spinal localization of the agent is stressed. In contrast with publications which analyze adults, it has a better prognosis.Apesar da incidência das infecções por Staphylococcus aureus ter aumentado, este permanece como uma causa relativamente incomum de meningite.

    NSAIDs-induced urticaria and/or angioedema (NIUA) is the most frequent entity of hypersensitivity reactions to NSAIDs. The underlying cause is considered to be because of a nonspecific immunological mechanism in which mast cells are key players. We studied the association of nine single nucleotide polymorphisms in five genes involved in mast cell activation (SYK, LAT1, PLCG1, PLA2G4A, and TNFRSF11A) in 450 NIUA patients and 500 controls. We identified several statistically significant associations when stratifying patients by symptoms: PLA2G4A rs12746200 (urticaria vs. controls, Pc=0.005). PLCG1 rs2228246 (angioedema vs. controls; Pc=0.044), and TNFRS11A rs1805034 (urticaria+angioedema vs. controls; Pc=0.041). The frequency of haplotype PLCG1 rs753381-rs2228246 (C-G) in angioedema-NIUA patients was lower than that in controls (Pc=0.040). In addition, the haplotype frequency of TNFRS11A rs1805034-rs35211496 (C-T) was higher among urticaria-NIUA and urticaria+angioedema-NIUA patients than the controls (Pc=0.045 and 0.046). Our results shed light on the involvement of variants in genes related to non-immunological mast cell activation in NIUA.

    Hereditary angioedema with C1-inhibitor deficiency (C1-INH-HAE) impairs health-related quality of life (HRQoL). The objective of this study was to assess HRQoL outcomes in patients self-administering subcutaneous C1-INH (C1-INH[SC]; HAEGARDA) for routine prevention of HAE attacks. Post hoc analysis of data from the placebo-controlled, crossover phase III COMPACT study (Clinical Studies for Optimal Management of Preventing Angioedema with Low-Volume Subcutaneous C1-Inhibitor Replacement Therapy). Ninety patients with C1-INH-HAE were randomized to 1 of 4 treatment sequences: C1-INH(SC) 40 or 60 IU/kg twice weekly for 16 weeks, preceded or followed by 16 weeks of twice weekly placebo injections. All HAE attacks were treated with open-label on-demand treatment as necessary. HRQoL assessments at week 14 (last visit) included the European Quality of Life-5 Dimensions Questionnaire (EQ-5D-3L), the Hospital Anxiety and Depression Scale (HADS), the Work Productivity and Activity Impairment Questionnaire (WPAI), and the Treatment Satisfaction Questionnaire for Medication (TSQM). Compared with placebo (on-demand treatment alone), treatment with twice weekly C1-INH(SC) (both doses combined) was associated with better EQ-5D visual analog scale general health, less HADS anxiety, less WPAI presenteeism, work productivity loss, and activity impairment, and greater TSQM effectiveness and overall treatment satisfaction. More patients self-reported a "good/excellent" response during routine prevention with C1-INH(SC) compared with on-demand only (placebo prophylaxis) management. For each HRQoL measure, a greater proportion of patients had a clinically meaningful improvement during C1-INH(SC) treatment compared with placebo. In patients with frequent HAE attacks, a treatment strategy of routine prevention with self-administered twice weekly C1-INH(SC) had a greater impact on improving multiple HAE-related HRQoL impairments, most notably anxiety and work productivity, compared with on

    Hereditary angioedema (HAE) is a rare, autosomal dominant disorder characterized by recurrent acute attacks of swelling of the larynx, abdomen, and periphery. This study was designed to assess the humanistic burden of illness associated with HAE. HAE burden was assessed via a web-based survey of patients that solicited information on attack characterization, treatment, side effects, pain, and functional and emotional burden of disease management. In addition to HAE-specific sections, the survey used three standardized instruments to compare HAE patient data to normative (healthy) and chronic disease populations: the 12-Item Short Form (SF-12) Health Survey, the Work Productivity and Activity Impairment-General Health (WPAI-GH) questionnaire, and the Hamilton Depression Inventory-Short Form (HDI-SF). A total of 457 HAE patients responded to the survey (response rate, ∼19%). Patients reported significantly poorer health-related quality of life versus population norms, based on the SF-12 Physical Component Summary (mean, 43.7 versus 49.6; p 8.5, indicative of depressive symptomatology. Productivity was also markedly impaired in all WPAI-GH categories, including 34% overall work impairment. Because of their most recent HAE attack, workers lost a mean of 3.3 days; students lost a mean of 1.9 days. HAE results in considerable humanistic burden to patients across physical and mental health domains; negatively impacts education, career, and work productivity; and compounds the substantial economic burdens that are reported separately.

    Angioedema (AE) is a clinical syndrome characterized by localised swelling lasting several hours. The swelling is often recurring and can be lethal if it is located in the laryngeal region. Much progress has been made recently in the treatment of acute episodes, but no consensus has been reached on maintenance treatment. We have performed a national retrospective observational study to assess the use of tranexamic acid (TA) as maintenance treatment for non-histaminergic AE [hereditary AE (HAE) or idiopathic non-histaminergic AE]. Records for 64 cases were collected from 1 October 2012 to 31 August 2013; 37 of these were included (12 HAE with C1-inhibitor deficiency, six with HAE with normal C1-inhibitor and 19 idiopathic non-histaminergic AE). When treated with TA over six months, the number of attacks was reduced by 75% in 17 patients, 10 patients showed a lower level of reduction and 10 had the same number of attacks. In no instances were symptoms increased. No thromboembolic events were observed, and the main side effects were digestive in nature. Thus, TA, which is well tolerated and inexpensive, appears to be an effective maintenance treatment for some patients with HAE or idiopathic non-histaminergic AE. PMID:24827773

    BACKGROUND: Treatment of hereditary angioedema (HAE) in 'older adults' (those aged ≥65 years) has not been well studied. The international Berinert Patient Registry collected data on the use of intravenous plasma-derived, pasteurized, nanofiltered C1-inhibitor concentrate (pnfC1-INH; Berinert......(®)/CSL Behring) in patients of any age, including many older adults. METHODS: This observational registry, conducted from 2010 to 2014 at 30 US and seven European sites, gathered prospective (post-enrollment) and retrospective (pre-enrollment) usage and adverse event (AE) data on subjects treated with pnfC1-INH....... RESULTS: The registry documented 1701 pnfC1-INH infusions in 27 older adults. A total of 1511 HAE attacks treated with pnfC1-INH administration were reported among 25 of the 27 (92.6 %) older adults. Among the older adults, mean (standard deviation [SD]) (8.8 [4.1] IU/kg) and median (6.4 IU/kg) pnfC1-INH...

    Full Text Available Hereditary angioedema due to C1-inhibitor deficiency (C1-INH-HAE is a rare, autosomal dominant disorder. The management of pregnant patients with C1-INH-HAE is a challenge for the physician. Intravenous plasma-derived nanofiltered C1-INH (pdC1INH is the only recommended option throughout pregnancy, postpartum, and breastfeeding period. In order to increase pregnancy rates, physicians use fertilization therapies increasing endogen levels of estrogens. Therefore, these techniques can provoke an increase in the number and severity of edema attacks in C1-INH-HAE. Our patient is a 32-year-old female, diagnosed with C1-INH-HAE type 1 since 2004. She had been taking danazol 50–200 mg/day for 9 years. Due to her pregnancy plans in 2013, danazol was discontinued. PdC1INH was prescribed regularly for prophylactic purpose. Triplet pregnancy occurred by in vitro fertilization using luteinizing hormone-releasing hormone (LHRH injections. In our patient, LHRH injections were done four times without causing any severe attack during in vitro fertilization. Angioedema did not worsen during pregnancy and delivery due to the prophylactic use of intravenous pdC1INH in our patient. According to the attack frequency and severity, there was no difference between the three pregnancy trimesters. To our knowledge, this is the first published case of C1-INH-HAE receiving in vitro fertilization therapies without any angioedema attacks during pregnancy and delivery and eventually having healthy triplets with the prophylactic use of intravenous pdC1INH.

    Neutralizing autoantibodies (NAbs) against plasma serpin C1-inhibitor (C1-inh) are implicated in the rare disorder, acquired angioedema (AAE). There is insufficient understanding of the process of antibody formation and its correlation with disease progression and severity. We have developed an ELISA for detecting neutralizing capacity of anti-C1-inh positive plasma samples that can be used to study changes in NAb repertoire in patient plasma over the course of disease. The ELISA is based on the specific interaction of active C1-inh with its target protease C1s. Decrease in the amount of C1s bound to immobilized C1-inh in the presence of test samples is proportional to the neutralizing capacity of the sample. Assay specificity, intra- and inter-assay variation and assay cut-off are determined using anti-C1-inh antibodies. Assay capability is demonstrated using plasma samples from AAE patients. The assay is specific to a neutralizing anti-C1-inh antibody and shows no interference by a non-neutralizing anti-C1-inh antibody or by the plasma matrix. Intra-assay and inter-assay variations are determined as 17 and 18% respectively. Neutralizing capacity of antibody positive AAE patient plasma samples (n=16) with IgG or IgM type antibodies is readily determined. All samples show positive neutralizing capacity. We have developed a robust, specific and semi-quantitative assay to detect the neutralizing capacity of plasma samples containing anti-C1-inh antibodies. This assay can be an important tool for the study of clinical implications of anti-C1-inh NAbs. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available CONTEXT AND OBJECTIVE: Hereditary angioedema (HAE with C1 inhibitor deficiency manifests as recurrent episodes of edema involving the skin, upper respiratory tract and gastrointestinal tract. It can be lethal due to asphyxia. The aim here was to evaluate the response to therapy for these attacks using icatibant, an inhibitor of the bradykinin receptor, which was recently introduced into Brazil.DESIGN AND SETTING: Prospective experimental single-cohort study on the efficacy and safety of icatibant for HAE patients.METHODS: Patients with a confirmed HAE diagnosis were enrolled according to symptoms and regardless of the time since onset of the attack. Icatibant was administered in accordance with the protocol that has been approved in Brazil. Symptom severity was assessed continuously and adverse events were monitored.RESULTS: 24 attacks in 20 HAE patients were treated (female/male 19:1; 19-55 years; median 29 years of age. The symptoms were: subcutaneous edema (22/24; abdominal pain (15/24 and upper airway obstruction (10/24. The time taken until onset of relief was: 5-10 minutes (5/24; 20.8%; 10-20 (5/24; 20.8%; 20-30 (8/24; 33.4%; 30-60 (5/24; 20.8%; and 2 hours (1/24; 4.3%. The time taken for complete resolution of symptoms ranged from 4.3 to 33.4 hours. Adverse effects were only reported at injection sites. Mild to moderate erythema and/or feelings of burning were reported by 15/24 patients, itching by 3 and no adverse effects in 6.CONCLUSION: HAE type I patients who received icatibant responded promptly; most achieved improved symptom severity within 30 minutes. Local adverse events occurred in 75% of the patients.

    Hereditary angioedema due to C1-esterase inhibitor deficiency (HAE-C1-INH) is a life-threatening disease. To describe the clinical characteristics and management of patients with HAE-C1-INH during routine clinical practice. An observational, retrospective study was performed in patients with HAE-C1-INH. Demographic, clinical, and analytical data were collected from 2 periods: period A (October 2009-September 2010) and period B (October 2007-September 2009). We studied 112 patients with HAE-C1-INH (57.1% females). Age at onset of symptoms was 14.4 years (lower in patients who had experienced attacks in the previous year). In period B (n=87), 62.1% of patients presented at least 1 edema attack (median, 3.5 attacks/patient/2 years), and 19.1% of attacks were treated. In period A (n=77), 58.4% of patients were on maintenance therapy. Stanozolol was the most widely used drug (48.9%), with a mean weekly dose of 6.7 mg. At least 1 attack was recorded in 72.7% of patients (median, 3.0 attacks/patient/year), and 31.5% of the attacks were treated. Treatment of acute attacks increased by 12.4%. Age at onset of symptoms is associated with clinical expression of disease. The higher age at onset of symptoms, the fewer number of attacks per patient and year, and the lower dose of attenuated androgens necessary to control the disease than in other series lead us to hypothesize that HAE-C1-INH could have a less severe expression in Spain. Acute attacks seem to be treated increasingly often.

    Full Text Available O presente artigo aborda a temática acerca dos efeitos da vacância por posse em cargo inacumulável, prevista na Lei n.º 8.112/90 (Estatuto do Servidor Pú­blico Civil Federal, no art. 33, inciso VIII, e a polêmica existente em torno da (inexistência de direito adquirido à preservação dos direitos personalíssimos já incorporados ao patrimônio jurídico do servidor público durante a investi­dura anterior. O estudo tem por finalidade investigar se o entendimento que vem sendo conferido pelos órgãos e entidades da Administração Pública fe­deral ao referido instituto, restringindo sua eficácia à continuidade de apenas algumas vantagens funcionais (por exemplo, férias e regime previdenciário, é harmônico com a garantia do direito adquirido e com os princípios consti­tucionais pertinentes ao assunto, especialmente o princípio da razoabilidade. Isso porque, diferentemente das demais hipóteses de vacância que resultam na interrupção do vínculo com a Administração Pública, a vacância por posse em cargo inacumulável não provoca a solução de continuidade, autorizando o raciocínio de que, nesse caso, os benefícios e vantagens sujeitos ao respec­tivo implemento dos requisitos fático-legais, uma vez já consumados, devem ser preservados. Ainda mais em se tratando de situações que vêm se tornando frequentes na carreira do Magistério Superior Federal, em que a mudança de vínculo ocorre muitas vezes entre cargos idênticos, dentro da mesma pessoa jurídica de direito público, entre unidades acadêmicas ou departamentais distintas. O artigo visa, então, estabelecer uma exegese jurídica diferencial para uma situação que reclama, ao nosso sentir, um tratamento igualmente singular, afastando a tese geral de inexistência de direito adquirido a regime jurídico, já pacificado na jurisprudência dos tribunais brasileiros.

As clinical trials in patients with rare diseases are limited, prescribers and patients have to rely on spontaneous adverse drug reaction (ADR reports for obtaining major information about the serious, rarely occurring, and unknown ADRs. In this study, we aimed to characterize ADRs reported for HAE medications in Europe from 2007 to 2013. ADR reports submitted for C1-inibitors and bradykinin receptor antagonists to the European ADR database, EudraVigilance (EV, were included in this study. The ADR reports were categorized with respect to age and sex of the patients, category of the reporter, type and seriousness of the reported ADRs, and medications. The unit of analysis was one adverse event (AE. Totally, 187 AEs were located in EV, and of these, 138 AEs were reported for Cinryze® (C1-inhibitor (73% of the total and 49 AEs for Firazyr® (icatibant (26% of the total AEs. Approximately 60% of all AEs were serious, including three fatal cases. Less than 5% of AEs were reported in children. In total, 62% of AEs were reported for women and 38% for men. For both Cinryze® and Firazyr®, the majority of reported AEs were of the type “general disorders and administration site conditions”. For Cinryze®, a large number of AEs of the type “HAE” and “drug ineffective” was reported, but only few of these were serious. For Firazyr®, several nonserious reports on injection site reactions were reported. In conclusion, this study showed that in EV, several ADR reports from use of HAE medications were identified, and a large number of these were

    Full Text Available Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA is increasingly recognized as an important pathogen causing skin and soft tissue infections as well as necrotizing pneumonia. We describe a case of familial transmission of CA-MRSA between a 6-month-old boy and his mother in Santa Fe City, Argentina. Both isolates showed an identical antimicrobial susceptibility profile, carried type IV SCCmec and harboured the pvl and the lnu(A genes. Isolates showed indistinguishable SmaI-PFGE patterns confirming their genetic relationship. These results corroborate the intrafamilial transmission of CA-MRSA and might associate this strain with the repetitive events of furunculosis within the family.Staphylococcus aureus resistente a la meticilina adquirido en la comunidad (SARM-AC es reconocido como un patógeno importante que causa infecciones de piel y partes blandas y neumonía necrotizante. Describimos un caso de transmisión familiar de SARM-AC entre un nino de 6 meses de edad y su madre en la ciudad de Santa Fe, Argentina. Ambos aislamientos mostraron idéntico perfil de sensibilidad a los antimicrobianos, tenían el SCCmec tipo IV, y contenían los genes pvl y lnu(A. Los aislamientos presentaron patrones de SmaI-PFGE indistinguibles entre sí, lo cual confirmó su relación genética. Estos resultados corroboran la transmisión intrafamiliar de SARM-AC; asimismo, este aislamiento podría asociarse con los eventos repetitivos de furunculosis en la familia.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are the most consumed drugs worldwide because of their efficacy and utility in the treatment of pain and inflammatory diseases. However, they are also responsible for an important number of adverse effects including hypersensitivity reactions. The most important group of these reactions is triggered by non-immunological, pharmacological mechanisms catalogued under the denomination of cross-intolerance (CRI), with acute urticaria/angioedema induced by multiple NSAIDs (MNSAID-UA) the most frequently associated clinical entity. A recent genome-wide association study identified the gene encoding the centrosomal protein of 68 KDa (CEP68) as the major locus associated with aspirin intolerance susceptibility in asthmatics. In this study, we aimed to assess the role of this locus in susceptibility to CRI to NSAIDs by examining 53 common gene variants in a total of 635 patients that were classified as MNSAID-UA (n = 399), airway exacerbations (n = 110) or blended pattern (n = 126), and 425 controls. We found in the MNSAID-UA group a number of variants (17) associated (lowest p-value = 1.13×10−6), including the non-synonymous Gly74Ser variant (rs7572857) previously associated with aspirin intolerance susceptibility in asthmatics. Although not being significant in the context of multiple testing, eight of these variants were also associated with exacerbated respiratory disease or blended reactions. Our results suggest that CEP68 gene variants may play an important role in MNSAID-UA susceptibility and, despite the different regulatory mechanisms involved depending on the specific affected organ, in the development of hypersensitivity reactions to NSAIDs.

O TNF-alfa (TNF-alfa lambda uma das principais citocinas envolvidas neste processo. OBJETIVO: Avaliar o papel do TNF-alfa na reabsorsão óssea e a ação dele no colesteatoma. MATERIAL E MÉTODOS: Foi realizado um levantamento e uma revisão crítica da literatura. RESULTADOS: Todos os autores estudados concordam com a importância do TNF-alfa no processo de reabsorção óssea presente no colesteatoma e com o grau de destruição observado. Diferentes trabalhos demonstraram que o TNF-alfa é capaz de provocar erosão óssea, através de diferentes vias de ação. Ele pode estimular a diferenciação e a maturação dos osteoclastos ou, ainda, agir na matriz óssea expondo-a à ação dos osteoclastos. Existe a possibilidade de inibir a ação do TNF-alfa, diminuindo seus efeitos e prevenindo a perda óssea em doenças como a artrite reumatóide. Não existe, entretanto, trabalhos específicos em colesteatoma. Não existe consenso sobre a sua localização. Estas diferenças, provavelmente, ocorrem devido à distribuição dos receptores. CONCLUSÃO: O TNF-alfa, presente no colesteatoma promove a reabsorsão óssea, juntamente com outras citocinas (RANKL e IL-1, estando relacionado com a presença de complicações.Cholesteatoma may cause bone erosion, with high morbidity and mortality rates.

    to AGA IgA optical density readings or AGA IgG readings. These drugs were associated with fewer positive EmA tests. CONCLUSIONS: Positive AGAA, AGAG or EmA results are probably nonspecific for the presence of celiac disease among autoimmune rheumatologic disease patients. The intake of prednisone and immunosuprressant drugs seems to reduce the prevalence of IgA EmA, but it does not interfere with antigliadin antibodies tests.Further studies are required to estimate more accurately the prevalence of this disease in rheumatologic patients.CONTEXTO: Tanto os pacientes com doenças reumatológicas autoimunes quanto os com doença celíaca costumam apresentar vários tipos de autoanticorpos, muitos deles ainda sem papel definido na etiopatogênese dessas afecções.

    Several religions recommend periods of fasting. One of the most frequently asked questions of MS patients before the holy month of Ramadan is weather fasting might have an unfavorable effect on their disease course. This debate became more challenging after the publication of experimental studies suggesting that calorie restriction prior to disease induction attenuates disease severity. We conducted this study to assess early and late effects of fasting on the animal model of MS, known as autoimmune encephalomyelitis. EAE was induced in the C57BL/6 mice, using Myelin Oligodendrocyte Glycopeptide  (MOG) 35-55 and they fasted every other day either after the appearance of the first clinical sign or 30 days after disease induction for ten days. Thereafter, the mice were sacrificed for further histological and immunological evaluations. Intermittent fasting after the establishment of EAE did not have any unfavorable effect on the course of disease. Moreover, fasting at the early phase of disease alleviated EAE severity by ameliorating spinal cord demyelination. Fasting suppressed the secretion of IFN-γ, TNF-α and raised IL-10 production in splenocytes. Fasting was also associated with a lower percent of cytotoxicity. Intermittent fasting not only had no unfavorable effect on EAE but also reduced EAE severity if started at early phase of disease.

    El ser humano reúne en sí una naturaleza biológica y una naturaleza cultural. Enfrentamos el problema de la fragmentación del conocimiento como consecuencia de la linealidad de las trayectorias de formación científica y la hiperespecialización. Más específicamente, enfrentamos los problemas derivados de la división entre ciencias naturales y ciencias sociales o humanas. Esta división proviene, en parte, de los fracasos de las estrategias reduccionistas de unificación de las ciencias (Agazzi, ...

    Full Text Available El objetivo de este trabajo es presentar los casos de paludismo por Plasmodium falciparum ocurridos en viajeros provenientes del África tropical, atendidos en el Hospital Alemán. Se definió paludismo de origen africano como la infección adquirida en un país del África subsahariana, diagnosticado y tratado en la Argentina. El diagnóstico se realizó por la clínica y la microscopía óptica en frotis de sangre periférica coloreados con Giemsa. Se revieron las historias clínicas de 11 pacientes adultos -cinco turistas y seis marineros mercantes- no oriundos de área endémica, sin condición inmunosupresora, ni morbilidad asociada, internados entre 1993 y 2007. El rango de edad fue de 21 a 48 años; nueve hombres y dos mujeres. Los pacientes fueron clasificados retrospectivamente en malaria grave (seis o no grave (cinco según cumplieran con uno o más de los criterios de gravedad de la Organización Mundial de la Salud. Todos presentaron fiebre como signo más significativo. Como complicaciones graves se observaron casos de insuficiencia renal, epistaxis, hemoglobinuria, hipoglucemia, edema pulmonar, acidosis y coma. Tres pacientes requirieron internación en la unidad de terapia intensiva. Todos sobrevivieron y solamente tres habían recibido la quimioprofilaxis correcta antes de viajar. El tratamiento se realizó con una o más de las siguientes drogas: mefloquina, quinidina, clindamicina y cotrimoxazol.The purpose of this paper is to present the cases of malaria caused by Plasmodium falciparum in travelers coming from tropical Africa, who were treated at the Hospital Alemán (Buenos Aires. African malaria was defined as an infection acquired in any country within Africa, diagnosed and treated in Argentina. Diagnostic tools included clinical features and optic microscopy with Giemsa stained peripheral blood films. We reviewed the medical records of 11 adult patients -five tourists and six sailors- with no history of malaria, immunosuppressive condition or associated morbidity, admitted from 1993 to 2007. The age ranged from 21 to 48 years old, nine of them were males and two females. The patients were retrospectively classified into severe malaria -six of them- or mild malaria -five of them- according to severity criteria established by the World Health Organization, within the first three days of the beginnings of the symptoms. All patients presented fever; severe complications included encephalitis, renal failure, bleeding, haemoglobinuria, hypoglycemia, and pulmonary edema. Three patients required admission at the intensive care unit; no patient died. Only three off them had received properly chemoprophylaxis before traveling; all received treatment with at least one of the following drugs: mefloquine, quinidine, clyndamicine and cotrimoxazol.

No es posible pronosticar si las formas agudas evolucionarán a UC, ya que todas son agudas al comienzo. La UC ocurre como espontánea (UCE o inducible (UCI. El diagnóstico es sencillo, pero incluye un minucioso estudio para descartar diagnósticos diferenciales; para UCI son útiles las pruebas de provocación en la caracterización y manejo. Los estudios complementarios se deben limitar y orientar según sospecha clínica. El tratamiento se divide en tres enfoques: evitación, eliminación o tratamiento del estímulo desencadenante o de la causa, y tratamiento farmacológico. Recientemente éste se modificó, con empleo de antihistamínicos de segunda generación como primera línea y aumento de dosis de antihistamínicos H1 no sedantes, hasta 4 veces, como segunda línea. Los antihistamínicos son fundamentales para tratar la UC; sin embargo, un 40% de los pacientes no logra un buen control pese al aumento de dosis y requiere otro medicamento adicional. La evidencia más reciente considera que un grupo de fármacos puede utilizarse como tercera línea en estos casos, para mejorar la calidad de vida y limitar la toxicidad por el uso frecuente o crónico de esteroides sistémicos. Se recomiendan para esta tercera línea solo 3 fármacos: omalizumab, ciclosporina A o antileucotrienos.

    Background Describe the frequency of positive results in autologus serum skin test among patients with cronic urticaria. Methods Trans-sectional study of patients with CIU refered to traitment in policlínica geral do Rio de Janeiro, brazil. Autologus serum intradermal injections were used to estabilished the sensitivity. Negative and positive controls were made with 0.9% intradermal saline solution and skin prick test with histamina 1:100 solution. Autoreactivity was considered positive when wheal reached 3 mm at least, 1.5 mm larger than saline solution at 30 minute interval. Antihistamines drugs were interrupeted 72 hours before test. Dates on race, age, sex, and informations about length and how often the symptoms persist, personal history of atopy (PHA) and angioedema (AE), autoimmune disease (AID) and physical (PF) and not physical factors (NPF) related with the worsening of urticaria were registered during appointment. K square and τ student tests were used in this work. Results Eighteen patients, from 2008, march to 2011, march, were investigated (15 f; 12 w; age 50,67 ± 16,93 yr). Eleven patients presented positive AAST (61.1%) with a mean wheal diameter = 9,64 ± 2,66 mm (negative control = 6,33 ± 3,63 mm; P 0.05). Conclusions The positive asst frequency was 61%, comparable to values found in the liretature. Association among social-demographic and clinical aspects was not observed. We emphasize the prevalence of joint pain and angioedema as associated symptoms and the more frequence of AID laborotory finds. The procedure proved safe and precise and worth value in the screening diagnosis of autoimune etiology for patients with CIU.

    Full Text Available INTRODUÇÃO: Sintomas musculoesqueléticos podem representar a primeira manifestação de imunodeficiências humorais primárias. A freqüência de deficiência seletiva de IgA em pacientes com artrite idiopática juvenil (AIJ símile e lúpus eritematoso sistêmico juvenil (LESJ é de 2% a 4% e de 1% a 4%, respectivamente. OBJETIVO: Descrever pacientes que apresentaram artrite como primeiro sinal de uma imunodeficiência humoral primária e determinar a prevalência de deficiência seletiva de IgA em pacientes com diagnóstico de AIJ e LESJ. PACIENTES E MÉTODOS: Entre janeiro de 1983 e dezembro de 2006, 4.876 pacientes foram acompanhados na Unidade de Reumatologia Pediátrica. Uma avaliação retrospectiva foi realizada em pacientes que apresentaram artrite como primeira manifestação de imunodeficiência. As imunodeficiências humorais foram classificadas em: deficiência seletiva de IgA, hipogamaglobulinemia e deficiência de subclasses de IgG. RESULTADOS: Onze (0,2% pacientes apresentaram imunodeficiências humorais: deficiência seletiva de IgA ocorreu em oito, imunodeficiência comum variável em dois e deficiência de subclasses de IgG em um. Cinco dos 11 pacientes apresentaram artrite aguda e seis apresentaram artrite crônica não-erosiva (AIJ símile. Dosagem de imunoglobulinas foi realizada em 70 dos 253 pacientes com AIJ e deficiência seletiva de IgA (IgA sérica INTRODUCTION: Rheumatologic findings may be the first manifestation of primary humoral immunodeficiencies. The frequency of selective IgA deficiency in patients with juvenile idiopathic arthritis (JIA like and juvenile systemic lupus erithematosus (JSLE is 2% to 4% and 1% to 4%, respectively. OBJECTIVE: To describe patients with primary humoral immunodeficiencies associated with arthritis and to determine the prevalence of selective IgA deficiency within JIA and JSLE patients. PATIENTS AND METHODS: From January 1983 to December 2006, 4.876 patients were followed at the Pediatric Rheumatology Unit. A retrospective evaluation was performed in patients that presented arthritis as the first clinical manifestation of immunodeficiency. The humoral immunodeficiencies were classified into selective IgA deficiency, hypogammaglobulinemia and IgG subclass deficiency. RESULTS: Eleven patients (0.2% had primary immunodeficiency: selective IgA deficiency occurred in 8, common variable immunodeficiency in two, and IgG subclass deficiency in one. Five of the 11 patients had an acute arthritis and six patients a chronic nonerosive arthritis (JIA-like. From the 253 JIA patients evaluated, 70 had IgA level evaluation done and 6 (8.5% presented complete IgA deficiency (serum IgA < 7 mg/dl (JIA-like. From the 45 JSLE patients with IgA levels evaluated, 3 (6.6% had selective IgA deficiency diagnosis. CONCLUSION: The present study showed a low prevalence of humoral immunodeficiency in patients with rheumatic diseases. However, this association suggests that similar defects in immune response could be related to both diseases and that prospective studies are needed to elucidate this hypothesis.

    Full Text Available O aparecimento do anticorpo contra fator VIII é um fenômeno bem estabelecido na hemofilia A, ocorrendo em 5 a 15% dos pacientes hemofílicos dos Estados Unidos, Inglaterra, Suécia e França. Nos pacientes não-hemofílicos o seu aparecimento é raro, podendo ocorrer em indivíduos saudáveis, principalmente idosos e mulheres no puerpério, pacientes com neoplasia maligna ou doenças autoimunes, como lúpus eritematoso sistêmico, artrite reumatoide e síndrome de Sjögren. Descrevemos o caso de uma paciente de 64 anos de idade, portadora de artrite reumatoide soropositiva há 23 anos, que há 10 dias desenvolveu equimoses e hematomas progressivos cuja investigação foi compatível com a presença de anticorpo contra fator VIII. Foi instituída terapia com metilprednisolona, ciclofosfamida endovenosa, imunoglobulina e reposição de complexo protrombínico, com remissão do quadro hemorrágico e negativação do anticorpo contra o fator VIII. Concluímos com esse caso que, apesar de ser rara, a presença de inibidores adquiridos do fator VIII deve ser pesquisada quando pacientes portadores de doença autoimune desenvolvem manifestações hemorrágicas associadas ao prolongamento do TTPA com TAP e contagem plaquetária normais.The occurrence of the antibody against factor VIII is a well-known phenomenon in hemophilia A, occuring in 5 to 15% of the hemophilic patients in the United States, England, Sweden and France. The development of factor VIII in non-hemophilic patients is rare and may occur in healthy individuals, mostly elderly and women in postpartum period, and in patients with malignant neoplasia or autoimmune diseases, such as systemic lupus erythematosus, rheumatoid arthritis and Sjögren's syndrome. We described the case of a 64-year-old female patient who has had seropositive rheumatoid arthritis for 23 years and presented with a ten-day history of progressive ecchymosis.

    Full Text Available Resumo: Licânia rigida Benth, popularmente oiticica, é uma vegetação típica no sertão nordestino. Destaca-se pelo alto teor de óleos em seus frutos e boa produtividade mesmo em épocas de seca, sendo capaz de promover desenvolvimento social e econômico para a região, pela utilização industrial de tintas, vernizes, sabão, lonas e esmaltes finos. Portanto, objetiva-se no presente estudo determinar a biometria, parâmetros físicos e rendimento lipídico do fruto da oiticica. Os frutos foram colhidos, selecionados, sanitizados. Em seguida, utilizou-se um paquímetro para a realização da biometria dos frutos e então sofreram separação em exocarpo-mesocarpo, endocarpo e amêndoas. As amostras foram trituradas e armazenadas ate procedidas as análises. Para a determinação do pH e condutividade, utilizou-se cerca de 5g de cada amostra, acrescidos de 50mL de água destilada e homogeneização, por conseguintemente foi utilizado o peagâmetro digital e condutivímetro, respectivamente. Para a acidez total titulável (ATT, utilizou-se as amostras anteriores e titulou-se com NaOH 0,1N, usando fenolftaleína como indicador, até as amostras alcançarem pH de 8,1. Procedeu-se a determinação do teor lipídico pelo método de Sohlext, com 2 a 5 g das amostras e hexano como solvente. Os frutos apresentaram peso médio de 9g. A variação do pH para as diferentes amostra foi irrelevante, enquanto o exocarpo-mesocarpo apresentou maior condutividade, com 308,6 mScm-1, e o endocarpo foi evidenciado por apresentar maior ATT, com 16,8%. Obteve-se na amêndoa maior percentual lipídico, com rendimento médio de 43,0%. Diante da importância e alta rentabilidade lipídica do fruto, faz-se necessário desenvolvimento de metodologias para utilização dessa matéria-prima.Biometrics, physical characteristics and yield fruit of lipid Licania rigid Benth purchased in the municipality of Pombal-PBAbstract: Licania rigid Benth, popularly oiticica, is typical vegetation in the northeastern hinterland.

Foi aplicado um survey a 413 consumidores e compradores de carne bovina em locais estrategicamente selecionados, a partir de uma estratificação da população. Entre os resultados, observou-se uma preferência desses consumidores pelos supermercados, como ponto de compra. A higiene do ambiente, a conservação dos produtos e a atuação de uma fiscalização sanitária superam o baixo preço oferecido pelo ponto de compra, como aspectos preferenciais. Em relação ao produto, os consumidores apreciam mais os aspectos visuais (cores da carne e da gordura, a limpeza da peça e aspectos relacionados ao sabor e maciez, que informações sobre o produto e sua origem apresentadas na embalagem.A survey was made to determine preferences in the purchase of beef by 413 consumers in Brasília. It was conducted by using their demographic profile, option for the point of purchase, preference of the point of purchase and meat characteristics. Locations were strategically chosen based upon a stratification of the population. Results disclosed that costumers had a preference for supermarkets. The hygiene of the environment, conservation of the products and the sanitary inspection were more important than an attractive price offered by the purchase point. Regarding the product, consumers preferred the better appearance of the meat color and fat, care in trimming the meat and aspects related to the expected taste and tenderness instead of the information and origin shown on the packaging.

    The use of radiation small fields, introduced by new techniques, can bring a considerable uncertainty in the precision of the acquired profiles, due to the conditions of lateral electronic non-equilibrium and the perturbations introduced by the detectors (volume effect and alteration of the charged particles flowing) [Das et al., 2007]. The development of new miniature detectors looks to diminish the uncertainty created by the material and the size of the sensitive volume of the dosimeter. For this reason, comparative measurements for three sizes of square field were carried out (20 mm, 10 mm and 5 mm, of side) using a detectors series: 3 ionization chambers (PTW-31003, IBA-CC04, PTW-31016), 2 diodes (PTW-60012, IBA-Sfd), thermoluminescent detectors micro-cubes of 1 mm of edge (TLD-700) and radiochromic s films EBT-3. These last two were used as reference detectors, due to their spatial high resolution and similar performance with Monte Carlo simulations [Francescon et al., 1998]. So much the thermoluminescent detectors as the radiochromic films resolved the profiles in a similar way. Both diodes responded correctly, but the rest of the detectors overestimated the gloom of the fields, which allows conclude that the used TLD (and both diodes) can resolve field sizes correctly, usually utilized in radio-surgery, without producing significant alterations in the acquired data.

    Full Text Available Introdução: A tireoidite de Hashimoto é o tipo de hipotireoidismo primário adquirido de causa auto-imune mais comum em região não-carente de iodo. Já o carcinoma papilífero de tireóide é o tipo mais comum de câncer de tireóide diferenciado na infância. Embora exista controvérsia na literatura quanto à associação entre Carcinoma Papilífero de Tireoide (CPT e Tireoidite de Hashimoto (TH, vários estudos detectaram incidência aumentada deste tipo de câncer em pacientes com TH. Objetivos: relatar o caso de uma paciente pediátrica com TH que desenvolveu CPT. Metodologia: revisão de dados obtidos e analisados do prontuário médico e pesquisa bibliográfica. Relato de caso: L. P, nascida em 25/07/1999, sexo feminino, foi encaminhada ao ambulatório de endocrinologia infantil da Policlínica Municipal de Sorocaba aos 9 anos de idade, devido ao desenvolvimento precoce de características sexuais secundárias, com aparecimento de pelos pubianos e de telarca há 1 ano. Ao exame físico, constatou-se desenvolvimento puberal segundo a classificação de Tanner, M3 P3 e tireóide palpável. Através de exames laboratoriais, foi diagnosticada com tireoidite de Hashimoto. Após 2 anos de tratamento, constatou-se aumento de tireóide em USG, diagnosticado como nódulo benigno em PAAF. No entanto, após 5 anos de seguimento, foi observada a presença de nódulo maligno, identificado como carcinoma papilífero da tireóide. Paciente foi submetida à tireoidectomia total com esvaziamento paratraqueal, devido as metástases em linfonodos. Após a cirurgia a paciente evoluiu bem, sem intercorrências e sem evidências de metástases funcionantes de carcinoma diferenciado de tireóide. Conclusão: É importante que os profissionais de saúde fiquem atentos à possibilidade de associação do CPT com a TH, quando houver mudança no padrão ultrassonográfico com a presença de linfoadenopatia cervical significativa.

    Full Text Available Os derivados lácteos são alimentos com excepcional valor nutritivo e amplamente consumido pela população mundial. Entretanto, são também excelentes meios de cultura para muitos micro-organismos, sendo, portanto, passíveis de contaminação por diferentes agentes microbiológicos, podendo levar a doenças manifestadas por ação de patógenos ou por suas toxinas. A obtenção de alimentos seguros depende dentre outros fatores, dos métodos de análises utilizados, os quais devem fornecer resultados rápidos e confiáveis que permitam o monitoramento da segurança microbiológica de alimentos, seja pela indústria ou pelos órgãos de fiscalização e para isso, diversos métodos alternativos têm sido desenvolvidos para a detecção e quantificação de patógenos. O primeiro objetivo do presente estudo foi caracterizar microbiologicamente, por metodologia clássica, amostras de doce de leite, leite condensado e queijo Minas Padrão com SIF, produzidos em vários estados do Brasil ecomercializados em supermercados de Juiz de Fora (MG. Foram feitas análises de contagem padrão em placas de mesófilos, bolores e leveduras, coliformes a 30ºC e a 45ºC, Staphylococcus spp. coagulase positiva e negativa, além da pesquisa de Salmonella sp. e Listeria monocytogenes. Altas contagens padrão em placas de mesófilos, leveduras e Staphylococcus spp.coagulase negativa foram encontradas nos três produtos. O segundo objetivo foi desenvolver uma metodologia alternativa à clássica, que apresentasse resultados mais rápidos e de alta especificidade para a detecção dos principais patógenos contaminantes de produtos lácteos e transmissores de doenças de origem alimentar, utilizando a técnica de PCR em tempo real. Foi padronizada uma reação multiplex para detecção de Salmonella entérica var thyphimurium e Staphylococcus aureus. O presente trabalho contribuirá com a rara literatura mundial sobre a microbiota contaminante do doce de leite, leite condensado e queijo Minas Padrão, fornecendo dados científicos à academia, autoridades regulamentadoras e indústria, vislumbrando a possibilidade da utilização de métodos de diagnóstico microbiológico alternativos aos clássicos, que forneçam resultados cada vez mais rápidos e mais sensíveis.

    Full Text Available Among physical activity curricular models used in the youth development field, the Teaching Personal and Social Responsibility (TPSR model has been widely incorporated in many underserved youth community and school physical education programs around the United States and the world (Hellison, 2011. Project Effort is an extended day program that uses the TPSR model as a framework. Literature has shown that TPSR programs and Project Effort have had a positive impact on the life of the participants. The purpose of this study was to investigate what TPSR values former participants’ have acquired in Project Effort and through other sources, and how they have guided their lives. A multiple-case design was implemented to understand this phenomenon. The findings showed that former participants considered that four TPSR values (i.e. respect, effort, self-direction, helping others were really important to their lives. Participants reported that they learned the TPSR values of helping others and leadership in Project Effort. Also they mentioned that they acquired the TPSR life skills of being reflective, teamwork, and goal setting in Project Effort. The TPSR value of helping others, and the TPSR life skill of being reflective acquired in Project Effort were most useful to the participants. Participants learned the TPSR value of self-direction and the TPSR values of respect and caring. Resumen Entre los modelos curriculares de actividad física utilizados para el desarrollo de la juventud, la enseñanza personalizada y el modelo de Enseñanza de la Responsabilidad Personal y Social (TPSR han sido ampliamente incorporados en muchas comunidades los jóvenes marginados y en programas de educación física escolares en Estados Unidos y en el mundo (Hellison, 2011. El proyecto esfuerzo es un programa de día extendido que utiliza el modelo TPSR como fundamento. La literatura ha demostrado que los programas TPSR y el Proyecto Esfuerzo han tenido un impacto positivo en la vida de los participantes. El propósito de este estudio fue investigar qué valores promocionados por el modelo TPSR habían aprendido los que fueron participantes a través del Proyecto Esfuerzo y a través de otras vías, y cómo estos valores habían guiado su vida. Se diseñó un estudio de caso múltiple para entender este fenómeno. Los resultados mostraron que los antiguos participantes consideraron que cuatro valores TPRS (esto es, respeto, esfuerzo, auto-dirección, ayudar a los demás eran realmente importante para sus vidas. También indicaron que aprendieron en el proyecto esfuerzo valores del TPRS como ayudar a los demás y de liderazgo. Estos participantes indicaron que en el Proyecto Esfuerzo habían aprendido habilidades del TPRS para la vida tales como ser reflexivos, trabajar en equipo y el establecimiento de objetivos. Los valores del TPSR ayudar a los demás y ser reflexivo que aprendieron en el Proyecto Esfuerzo fueron las más útiles para los participantes. Los participantes aprendieron valores del TPSR como la autodirección, el respeto de respeto y cariño hacia los demás.

MÉTODO: De 1395 tireoidectomias realizadas de 1994 a 2003, foram selecionadas 120 carcinomas diferenciados (27 foliculares e 93 papilíferos. Foram avaliadas as variáveis clínicas (idade e sexo com apresentação de freqüências e de sumários de medidas-resumo na descrição estatística. Para aferir a associação de tireoidite auto-imune e carcinoma diferenciado da tireóide em função dos achados histopatológicos, utilizou-se tabelas de contingência e análise pelo teste não paramétrico do quiquadrado de Pearson. Em todos os testes estatísticos foi adotado um nível de significância de 5% (p<0,05. RESULTADOS: 11,1% dos carcinomas foliculares e 18,3% dos carcinomas papilíferos estão associados à tireoidite auto-imune. Existe uma relação de freqüências quatro vezes maior da tireoidite auto-imune com o carcinoma diferenciado da tireóide em comparação com outras doenças tireoideanas (16,7% X 3,6%. CONCLUSÕES: Tais resultados permitem inferir que a associação entre a tireoidite auto-imune e o carcinoma diferenciado da tireóide é mais que casual, exigindo uma observação clínico-laboratorial cuidadosa nos portadores da doença auto-imune.

    . Prolonged incubation of plasma deficient in both factor XII and C1-INH led to conversion of prekallikrein to kallikrein and cleavage of HK, as was seen in plasma from patients with hereditary angioedema but not plasma from healthy subjects. CONCLUSIONS: These results indicate that C1-INH stabilizes...... the prekallikrein-HK complex to prevent HK cleavage either by prekallikrein or by prekallikrein-HK autoactivation to generate kallikrein. In patients with hereditary angioedema, kallikrein and bradykinin formation can occur without invoking factor XII activation, although the kallikrein formed can rapidly activate...

    Full Text Available Malaria is an infectious disease caused by protozoa of the genus Plasmodium. Cutaneous lesions in malaria are rarely reported and include urticaria, angioedema, petechiae, purpura, and disseminated intravascular coagulation (DIC. Here, five malaria cases associated with cutaneous lesions have been described. Out of the five cases of malaria, two were associated with urticaria and angioedema, one case was associated with urticaria, and other two were associated with reticulated blotchy erythema with petechiae. Most of the cutaneous lesions in malaria were nonspecific and reflected the different immunopathological mechanism in malarial infection.

    BACKGROUND AND CONCLUSION: A case of a 41-year-old patient with a 5-year history of chronic recurrent angioedema, refractory to conservative treatment is presented. The results of the case report suggest that in differential diagnosis of angioedema, in addition to usual causes, the allergist-immunologist needs to consider Melkersson-Rosenthal syndrome, which can present with a variety of symptom-combinations of the classic triad. The distinguishing characteristics of the Melkersson-Rosenthal syndrome are its refractoriness to the usual anti-inflammatory therapy and the need to consider corrective cosmetic surgery, which may benefit some patients.

  14. Perfil epidemiológico dos pacientes com vitiligo e sua associação com doenças da tireoide Vitiligo epidemiological profile and the association with thyroid disease

    Directory of Open Access Journals (Sweden)

    2011-04-01

    Full Text Available FUNDAMENTO: O vitiligo é considerado a hipomelanose adquirida mais frequente. Apesar de sua etiopatogenia ser incerta, acredita-se que a etiologia autoimune seja a mais plausível, teoria que se fundamenta na concomitância de vitiligo com doenças autoimunes. OBJETIVOS: Traçar o perfil epidemiológico dos pacientes com vitiligo e estimar a prevalência da associação de vitiligo com doenças autoimunes da tireoide. MÉTODOS: Efetuou-se um estudo transversal, analisando-se prontuários dos pacientes com diagnóstico de vitiligo atendidos no Ambulatório de Dermatologia AME-Unisul e do HU-UFSC. Avaliaram-se as características clínicas e laboratoriais desses pacientes. RESULTADOS: Foram avaliados 85 prontuários, sendo 56 do sexo feminino, com idade média de 37,14 anos e idade média de início de 25,25 anos. O vitiligo vulgar ocorreu em 70,6% dos casos. As doenças autoimunes da tireoide foram encontradas em 22,4% dos casos. Outras doenças autoimunes foram identificadas em 5,9% dos casos. Os pacientes com anticorpos antitireoidianos positivos revelaram uma probabilidade elevada de extensão do vitiligo maior que 25%. Não houve diferença estatística quanto às características clínicas do vitiligo em portadores ou não de tireoidite autoimune com alteração hormonal. CONCLUSÃO: Os resultados deste estudo são similares aos de outros autores, mostrando que as doenças autoimunes da tireoide são mais frequentes nos pacientes com vitiligo.BACKGROUND: Vitiligo is considered the most frequent acquired hypomelanosis. Although its pathogenesis is uncertain, it is believed that autoimmune etiology is the most plausible. This theory is based on the coexistence of vitiligo with autoimmune diseases. OBJECTIVES: To describe the epidemiological profile of vitiligo patients and to estimate the prevalence of the association of vitiligo with autoimmune thyroid diseases.
