Abstract Urticaria is a distinctive pattern of inflammatory re sponse of the skin and/or mucous membranes charac terized by the sudden appearance of vanishing wheals, angioedema, or both, associated with pruritus. Acute forms are frequent and limited to outbreaks of less than 6 weeks; while the chronic ones have a prevalence of less than 1%, longer duration and can be spontaneous or inducible. The etiopathogenic mechanisms involved in this disease include autoallergy, autoimmunity, and inflam mation with cell activation, mainly of the mast cell, leading to its degranulation with the release of vasoac tive mediators. Along its approach, diagnostic confirmation, search for indicators of its etiopathogenesis, detection of cofactors that can modulate its activity, recognition of comorbidi ties, evaluation of possible biomarkers and the assess ment of disease activity, impact and control are essential. The pharmacological management aims to control the symptoms, until the urticaria, which is self-resolv ing, is gone. This is described in a stepwise fashion with increasing complexity.

OBJECTIVE: To describe health relaed quality of life in a cohort of stable adult outpatients with hereditary an-gioedema (HAE) with validated tools. METHODS: An observational, cross-sectional, and descriptive study was performed, carried out in patients with hereditary angioedema, coming from the City of Buenos Aires and its provinces: Corrientes, Chubut, Entre Ríos and Santa Fe. The HAE-QoL and SF-12v2 health questionnaires were applied to assess the related quality of life. with health. RESULTS: 100 patients were included; median age: 41.5 years (range: 18-77); 65% were female, and 79% had type 1 HAE. Asymptomatic, mild, moderate and severe cases accounted for 6, 29, 38, and 27% of participants, respectively. Seventeen percent of patients were receiving long-term prophylaxis. Icatibant was the most fre-quent treatment for acute episodes. All health domains SF-12v2 scores were lower than expected in general population, excepting "vitality" and "physical functioning". Total and all specific domains HAE-QoL scores were reduced. Differences between women and men and in every age-defined group were demonstrated for sev-eral specific domains. CONCLUSIONS: Health relaed to quality life was notably reduced in Argentinean patients with HAE, when imple-menting the HAE.QoL, and SF-12v2 questionnaries. The need for multidisciplinary strategies approaching this complex disease is highlighted.
OBJECTIVO: Describir la calidad de vida relacionada con la saluden pacientes adultos, ambulatorios y estables con angioedema hereditario, mediante cuestionarios validados. MÉTODOS: Estudio descriptivo, transversal y observacional, llevado a cabo en pacientes con angioedema here-ditario, procedentes de la Ciudad de Buenos Aires y sus provincias: Corrientes, Chubut, Entre Ríos y Santa Fe. Se aplicaron los cuestionarios HAE-QoL y SF-12v2 para evaluar la calidad de vida relacionada con la salud. RESULTADOS: Se incluyeron 100 pacientes, con mediana de edad de 41.5 años (rango: 18-77), principalmente de género femenino (65%). La forma más frecuente de angioedema hereditario fue el tipo 1 (79%). Los casos asintomáticos, leves, moderados y severos representaron el 6, 29, 38 y 27%, respectivamente. El 17% recibía profilaxis a largo plazo. Icatibant fue el tratamiento más prescrito para los episodios agudos de angioedema. Todos los puntajes de los dominios de salud del SF-12v2 fueron menores de lo esperado, excepto "vitalidad" y "funcionamiento físico". Se observó disminución en los puntajes totales y en todos los dominios del HAE-QoL. Se reconocieron diferencias entre las mujeres y los hombres, y para grupo etario en los puntajes de los dominios específicos. CONCLUSIONES: La calidad de vida relacionada con la salud disminuyó considerablemente en pacientes argentinos con angioedema hereditario al aplicar los cuestionarios HAE-QoL y SF-12v2. Es importante desarrollar estra-tegias multidisciplinarias para abordar esta enfermedad compleja.

BACKGROUND: Although chronic urticaria (CU) is a common and primarily affects females, there is little data on how pregnancy interacts with the disease. OBJECTIVE: To analyse the treatment use by CU patients before, during and after pregnancy as well as outcomes of pregnancy. METHODS: PREG-CU is an international, multicentre study of the Urticaria Centers of Reference and Excellence network. Data were collected via a 47-item-questionnaire completed by CU patients who became pregnant during their disease course. RESULTS: Questionnaires from 288 CU patients from 13 countries were analysed. During pregnancy, most patients (60%) used urticaria medication including standard-dose second generation H1-antihistamines (35.1%), first generation H1-antihistamines (7.6%), high-dose second-generation H1-antihistamines (5.6%) and omalizumab (5.6%). The preterm birth rate was 10.2%; rates were similar between patients who did and did not receive treatment during pregnancy (11.6% vs. 8.7%, respectively). Emergency referrals for CU and twin birth were risk factors for preterm birth. The caesarean delivery rate was 51.3%. More than 90% of new-borns were healthy at birth. There was no link between any patient or disease characteristics or treatments and medical problems at birth. CONCLUSION: Most CU patients used treatment during pregnancy especially second-generation antihistamines which seem to be safe during pregnancy regardless of the trimester. The rates of preterm births and medical problems of new-borns in CU patients were similar to population norms and not linked to treatment used during pregnancy. Emergency referrals for CU increased the risk of preterm birth and emphasize the importance of sufficient treatment to keep urticaria under control during pregnancy.

BACKGROUND: Chronic urticaria (CU) predominantly affects women, and sex hormones can modulate disease activity in female CU patients. As of now, the impact of pregnancy on CU is largely unknown. AIM: To analyze the course and features of CU during and after pregnancy. PATIENTS AND METHODS: PREG-CU is an international, multicenter study of the Urticaria Centers of Reference and Excellence (UCARE) network. Data were collected via a 47-item questionnaire completed by CU patients, who became pregnant within the last 3 years. RESULTS: A total of 288 pregnancies of 288 CU patients from 13 countries were analyzed (mean age at pregnancy: 32.1 ± 6.1 years, duration of CU: 84.9 ± 74.5 months; CSU 66.9%, CSU + CIndU 20.3%, CIndU 12.8%).During pregnancy, 51.1% of patients rated their CU as improved, 28.9% as worse, and 20.0% as unchanged.CU exacerbations most commonly occurred exclusively during the third trimester (in 34 of 124 patients; 27.6%) or the first (28 of 124; 22.8%). The risk factors for worsening of CU during pregnancy were having mild disease and no angioedema before pregnancy, not taking treatment before pregnancy, CIndU, CU worsening during a previous pregnancy, treatment during pregnancy, and stress as a driver of exacerbations. After giving birth, urticaria disease activity remained unchanged in 43.8% of CU patients, whereas 37.4% and 18.1% experienced worsening and improvement, respectively. CONCLUSIONS: These results demonstrate the complex impact of pregnancy on the course of CU and help to better counsel patients who want to become pregnant and to manage CU during pregnancy.

BACKGROUND: There are very few studies about the prevalence of allergic rhinitis in Argentina. OBJECTIVE: To determine the prevalence of allergic rhinitis in a population of inhabitants between the ages of 5 and 44 in Argentina. METHODS: A cross-sectional national study in which a self-reported questionnaire was used. The included participants are between the ages of 5 and 44 and they reside in urban areas. The information was collected by phone. RESULTS: 3200 participants were surveyed: 51.8% were women, 37.6% were between the ages of 5 and 19, and 62.4%, were between the ages of 20 and 44. The global prevalence of symptoms of allergic rhinitis was of 20.5%; the most frequent symptoms were sneezing (58.5%) and nasal congestion (51.4%). Overall, 44.3% of the participants had a family history of allergies. Allergic rhinitis was more frequent in women; the prevalence was of 22.3% in the group of participants between the ages of 5 and 19, and of 19.4% in the group of participants between the ages of 20 and 40 (p=0.0545); 63.8% of participants with symptoms did not have a medical diagnosis. CONCLUSIONS: The results of this first cross-sectional national survey have confirmed the high prevalence of self-reported symptoms of allergic rhinitis in adults and children in Argentina, particularly in women.
Antecedentes: Existen pocos estudios sobre la prevalencia de rinitis alérgica en Argentina. Objetivo: Determinar la prevalencia de rinitis alérgica en una población entre cinco y 44 años de edad en Argentina. Métodos: Estudio transversal nacional en el que se utilizó un cuestionario autoinformado. Se incluyeron participantes entre cinco y 44 años de edad residentes en áreas urbanas. La información se recolectó telefónicamente. Resultados: Se encuestaron 3200 participantes: 51.8 % del sexo femenino, 37.6 % tenía entre cinco y 19 años y 62.4 % entre 20 y 44 años. La prevalencia global de síntomas de rinitis alérgica fue de 20.5 %; los síntomas más frecuentes fueron los estornudos (58.5 %) y la congestión nasal (51.4 %). En general, 44.3 % de los participantes tenía antecedentes familiares de alergia. La rinitis alérgica fue más frecuente en las mujeres; la prevalencia fue de 22.3 % en el grupo de cinco a 19 años y de 19.4 % en el de 20 a 44 años (p = 0.0545); 63.8 % de los participantes con síntomas no tenía diagnóstico médico. Conclusiones: Los resultados de esta primera encuesta transversal nacional confirman la alta prevalencia de síntomas autoinformados de rinitis alérgica en adultos y niños en Argentina, especialmente en las mujeres.

PURPOSE OF REVIEW: Since omalizumab has been approved for urticaria, numerous randomized and real-life observational trials have been published. We reviewed the period January 2017-February 2018. RECENT FINDINGS: Omalizumab is effective for the control of urticaria recalcitrant to antihistamines in different populations globally. The ratio of total serum IgE 4-week/baseline ≥2 can predict response with a high likelihood. In observational real-life trials, doses have been adjusted on an individual basis: in some populations, up to two-thirds of the patients can be controlled with 150 mg/month; however, others are still not controlled with 300 mg/month. In these, 150 mg bimonthly could be tried, before up-dosing to 450 mg/month. On the long run (up to 3 years) omalizumab kept its efficacy. In many patients, dosing intervals could be augmented (6-8 weeks, some even more). After a 12-month treatment, about 20% showed long-term remission without relapse. Some biomarkers are being detected. Adjusting omalizumab doses in urticaria patients could enhance efficacy (shortening dosing interval and/or augmenting dose) and save costs (after 12 months: extending dosing interval and/or reducing dose).

This interdisciplinary paper summarizes the news in the diagnosis and treatment of chronic urticaria (CU), and provides concepts, definitions and evidence-based suggestions for its management. Urticaria occurs in at least 20% of the population at some point in their lives. Acute urticaria (less than 6 weeks' duration), differs from CU in its etiology, but the onset of this disease is always acute. CU may occur as spontaneous (SCU) or induced (ICU). The diagnosis is simple, although a careful evaluation is necessary for differential diagnosis. ICU's diagnosis is mainly clinical, even if provocation tests can be useful. Supplementary studies should be limited and based on the clinical suspicion. Treatment may be divided into three approaches: avoidance, elimination or treatment of the cause, and pharmacological treatment. Recently treatment has been modified with the use of second-generation antihistamines as first-line and increased doses of nonsedating H1 antihistamines, up to 4 times, as second line. Antihistamines are essential to treat CU; however, 40% of patients do not achieve good control despite increased doses and require additional treatment. The most recent evidence indicates a group of drugs to be used as third line in these cases, to improve quality of life and to limit toxicity from frequent or chronic use of systemic steroids. Only 3 drugs are recommended as third line: omalizumab, cyclosporin A or anti-leukotrienes.

Se actualiza el diagnóstico de la urticaria crónica (UC) y los conceptos, definiciones y sugerencias basados en la evidencia para su tratamiento. La urticaria ocurre en al menos 20% de la población en algún momento de la vida. Su etiología difiere en la forma aguda (menos de 6 semanas), y en la crónica. 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.

La prevalencia de diabetes mellitus (DM) ha mostrado un rápido incremento en los últimos años en Cuba. La estrategia de población de alto riesgo es la principal prioridad dentro del Programa Nacional de Atención Integral al diabético. Objetivo: Determinar el comportamiento de la prevalencia e incidencia por DM según variables socio-demográficas en el período 1998 û 2009 en Cuba. Métodos: Se realizó un análisis de los informes anuales emitidos por el Registro Nacional de Dispensarización de diabetes mellitus (RND-DM) entre 1998 a 2009. Para estudiar la tendencia y su representación según el modelo lineal, se usaron los métodos del mínimo cuadrado y porcentaje de cambio. Resultados: Los cambios en la incidencia ocurrieron principalmente en el período de 1998 al 2002, en los grupos de edades 65 años y más y 25 a 59 años, con tasas de cambio de 83.4% y 83.1% respectivamente. Al sexo femenino le correspondieron las mayores tasas del período estudiado: 1.48 (1998), 2.69 (2002) y 2.7 (2009) (tasas por cada 1000 habitantes). Con respecto a la prevalencia, los grupos de edades con mayores tasas fueron los de 60 a 64 años, y 65 y más años. Al sexo femenino le correspondieron las mayores tasas del período: 25.69 (1998), 34.58 (2002) y 48.7 (2009) (tasas por cada 1000 habitantes). Conclusiones: Durante el periodo estudiado hubo un incremento de la incidencia y la prevalencia de DM. El sexo más afectado es el femenino. La tendencia lineal de la serie cronológica mostró un ascenso durante el período.
The prevalence of diabetes mellitus (DM) has shown a rapid increase in recent years in Cuba. The population at high risk strategy is the main priority within the National Programme for Integral Care of the diabetic patient. Objective: to determine the prevalence and incidence of DM behaviour according to socio-demographic variables between 1998 and 2009 in Cuba. Methods: An analysis of annual reports issued by the National Register of medical classification of diabetes mellitus (DMRND) from 1998 to 2009 was performed. To study the trend and its representation by the linear model, least square method and rate of change were used. Results: incidence rate changes occurred mainly in the period from 1998 to 2002, in the age groups of 65 years and older and 25 to 59 years, with change rates of 83.4% and 83.1% respectively. Females accounted for the highest change rates in the study period: 1.48 (1998), 2.69 (2002) and 2.7 (2009) (rates per 1000 inhabitants). With regard to prevalence, age groups with higher rates were 60 to 64 years, and 65 and over. Also females accounted for the highest rates in the period: 25.69 (1998), 34.58 (2002) and 48.7 (2009) (rates per 1000 inhabitants). Conclusions: there was an increase in the incidence and prevalence of DM during the study period. Females are the most affected. The linear trend of the time series showed a rise during the period.

This randomised, double-blind, placebo-controlled, parallel-group, international, dose-ranging study investigated the effect of treatment with rupatadine 5, 10 and 20 mg once daily for 4 weeks on symptoms and interference with daily activities and sleep in 12-65 years-old patients with moderate-to-severe chronic idiopathic urticaria (CIU). Rupatadine 10 and 20 mg significantly reduced pruritus severity by 62.05% and 71.87% respectively, from baseline, over a period of 4 weeks compared to reduction with placebo by 46.59% (p < 0.05). Linear trends were noted for reductions in mean number of wheals and interference with daily activities and sleep with rupatadine 10 and 20 mg over the 4-week treatment period. The two most frequently reported AEs were somnolence (2.90% for placebo, 4.29% for 5 mg-, 5.41% for 10 mg- and 21.43% for 20 mg-rupatadine-treated group) and headache (4.35% for placebo, 2.86% for 5 mg-, 4.05% for 10 mg- and 4.29% for 20 mg-rupatadine-treated group). These findings suggest that rupatadine 10 and 20 mg is a fast-acting, efficacious and safe treatment for the management of patients with moderate-to-severe CIU. Rupatadine decreased pruritus severity, in a dose- and time-dependent manner.
