Impact of chronic urticaria on the quality of life of patients followed up at a university hospital

Abstract BACKGROUND: Chronic urticaria is a debilitating disease that considerably affects health-related quality of life, and the Chronic Urticaria Quality of Life Questionnaire is the only questionnaire specifically designed for its evaluation. OBJECTIVE: To evaluate the quality of life of patients with chronic urticaria, using the Brazilian Portuguese version of the Chronic Urticaria Quality of Life Questionnaire. METHODS: The Chronic Urticaria Quality of Life Questionnaire was self-administered in 112 chronic urticaria patients and disease activity was assessed through the Urticaria Activity Score. Clinical and socio-demographic characteristics of patients were studied, such as: age, sex, etiologic diagnosis of chronic urticaria, duration of disease and Urticaria Activity Score. RESULTS: The population studied was composed 85.72% of women with a mean age of 46 years (18-90), while the median disease duration period was 10 years (3 months-60 years). Regarding the etiologic diagnosis, 48.22% had chronic spontaneous urticaria; 22.32% associated with inducible urticaria, 28.57% with chronic autoimmune urticaria, and 23.21% had physical urticaria alone. Disease activity evaluated using the Urticaria Activity Score was 1.04 ± 1.61 (0-6). The total score for the Chronic Urticaria Quality of Life Questionnaire was 36 (0-100) and dimension I (sleep/mental status/eating) had a greater impact on quality of life. The items with the highest mean scores were nervousness and shame over lesions, while the items with the lowest scores were lip swelling and limitations on sporting activities. CONCLUSIONS: Chronic urticaria compromises patients' quality of life, mainly those with more severe disease or who are diagnosed with chronic autoimmune urticaria.

Estudo da qualidade de vida nos pacientes com urticária crônica / Quality of life assessment in patients with chronic urticaria

FUNDAMENTOS: A urticária crônica compromete o doente por interferir nas atividades diárias, prejudicar a autoestima e as relações interpessoais. Os profissionais de saúde subestimam seu impacto na qualidade de vida dos doentes. OBJETIVOS: Avaliar a qualidade de vida com questionário específico e genérico. Compará-la entre os tipos clínicos de urticária crônica e avaliar se o angioedema piora a qualidade de vida. MÉTODOS: Participaram 62 doentes com urticária crônica, com sinais e sintomas da doença até 7 dias da consulta, que foram divididos em urticária crônica comum, urticária crônica física e urticária crônica mista. RESULTADOS: Observou-se predominância de mulheres (72,6 por cento), idade média de 39,8 anos, angioedema associado em 75,8 por cento dos doentes. Apresentaram mais angioedema doentes com urticária crônica comum (p=0,011) e mulheres (p=0,024). Quanto aos tipos clínicos, 32,3 por cento apresentaram urticária crônica comum, 27,4 por cento urticária crônica física e 40,3 por cento urticária crônica mista. O escore médio total do questionário específico foi 10,4. No questionário específico, os domínios mais comprometidos foram "Sintomas e sentimentos" e "Atividades diárias", e, no SF-36, "Aspectos físicos" e "Vitalidade". Houve comprometimento da qualidade de vida nas mulheres, nos doentes com até 30 anos, em primeira consulta, nos mais escolarizados, naqueles com até 1 ano de doença e naqueles com angioedema. CONCLUSÃO: A urticária crônica compromete a qualidade de vida medida pelos questionários específico e genérico. Não houve diferença estatisticamente significante na qualidade de vida entre os tipos clínicos. A presença do angioedema conferiu pior qualidade de vida aos doentes. Houve correlação estatisticamente significante entre os escores do questionário específico e do questionário genérico.

BACKGROUND: Chronic urticaria affects patients by interfering with their daily activities, damaging their self-esteem and negatively affecting their interpersonal relationships. Healthcare professionals may underestimate the impact of the condition on patients' quality of life. OBJECTIVES: To evaluate quality of life using one generic and one disease-specific health-related quality of life instrument; to compare quality of life between the different clinical types of chronic urticaria and to evaluate whether angioedema further impairs quality of life. METHODS: Sixty-two patients with chronic urticaria, who had had signs or symptoms of the disease within the preceding week, were divided into groups according to whether they had ordinary chronic urticaria, physical chronic urticaria or mixed chronic urticaria. RESULTS: There was a predominance of women in this study (72.6 percent). The mean age of patients was 39.8 years and angioedema was associated with chronic urticaria in 75.8 percent of cases. Associated angioedema was more commonly found in patients with ordinary chronic urticaria (p=0.011) and in women (p=0.024). With respect to the different clinical types, 32.3 percent of the patients had ordinary chronic urticaria, 27.4 percent had physical chronic urticaria and 40.3 percent had mixed chronic urticaria. Mean overall score for the disease-specific questionnaire was 10.4. In this questionnaire, the most affected domains were "symptoms and feelings" and "daily activities", while the most affected domains in the SF-36 were "physical role" and "vitality". Quality of life was found to be impaired in women, in patients of up to 30 years of age, in those attending a first consultation, in those with higher education levels, in patients who had had the disease for up to one year and in those with angioedema. CONCLUSION: Chronic urticaria affects quality of life, as measured using a disease-specific questionnaire and a generic questionnaire. There was no statistically significant difference between the clinical types. The presence of angioedema impaired patients' quality of life even further. There was a statistically significant correlation between the scores obtained using the disease-specific questionnaire and those obtained using the generic questionnaire.

Qualidade de vida em urticária crônica: inquérito em ambulatório público universitário, Botucatu (Brasil) / Quality of life in chronic urticaria: a survey at a public university outpatient clinic, Botucatu (Brazil)

OBJETIVO: Avaliar o impacto da urticária crônica na qualidade de vida dos pacientes de ambulatório universitário a partir do questionário DLQI (Dermatology Life Quality Index). MÉTODOS: Inquérito sobre o impacto na qualidade de vida infligido pela urticária crônica a partir do questionário DLQI validado para a língua portuguesa. Pacientes foram entrevistados durante suas consultas em ambulatório especializado, entre maio de 2009 e maio de 2010, em serviço público brasileiro (Botucatu-SP). Os escores do DLQI foram analisados segundo subgrupos: idade, gênero, escolaridade, tempo de doença e presença de angioedema. RESULTADOS: Foram entrevistados 100 pacientes com urticária crônica. Predominou o gênero feminino (86 por cento), a idade média foi de 41,8 anos, duração média da doença foi de seis anos e angioedema ocorreu em 82 por cento dos pacientes. O escore médio do DLQI foi de 13,5, caracterizando grave impacto à qualidade de vida, superior a hanseníase, psoríase, eczema atópico e carcinoma basocelular. Presença de angioedema se associou a maiores escores: 14,5 x 9,9 (p < 0,01). Pacientes do gênero feminino referiram maior impacto quanto ao vestuário, já o gênero masculino referiu quanto ao tratamento, trabalho e estudo (p < 0,05). CONCLUSÃO: Urticária crônica inflige grave comprometimento da qualidade de vida nos pacientes avaliados em serviço universitário brasileiro, especialmente nos portadores de angioedema.

OBJECTIVE: To evaluate the impact of chronic urticaria on quality of life of outpatients through the university questionnaire Dermatology Life Quality Index (DLQI). METHODS: Survey of the impact on quality of life caused by chronic urticaria, using the DLQI questionnaire validated for the Portuguese language. Patients were interviewed during visits to a specialized outpatient clinic between May 2009 and May 2010 at a Brazilian public service (Botucatu-SP). DLQI scores were analyzed according to the following subgroups: age, gender, education, disease duration, and presence of angioedema. RESULTS: We interviewed 100 patients with chronic urticaria. There was a female predominance (86 percent), mean age 41.8 years, mean disease duration of 6 years, and angioedema occurrence in 82 percent of patients. The mean DLQI score was 13.5, characterized by serious impact on quality of life, higher than Hansen's disease, psoriasis, atopic eczema, and basal cell carcinoma. The presence of angioedema was associated with higher scores: 14.5 x 9.9 (p < 0.01). Female patients reported greater impact on clothing, while male patients reported treatment interference with work and study (p < 0.05). CONCLUSION: Chronic urticaria seriously compromises the quality of life of patients evaluated at a university service in Brazil, particularly of patients with angioedema.
