Type D personality (TDp) is a stable personality type that has been associated with poor quality of life in the general population and in patients with a variety of diseases, such as cancer, cardiac diseases, and dermatological diseases (e.g. psoriasis). To date, the potential association between chronic spontaneous urticaria and TDp has not been studied. The aim of this study is to analyse the impact of TDp on patients with chronic spontaneous urticaria, regarding mood disturbances, quality of life, sexuality, and sleep disturbances. A cross-sectional study including 75 patients with chronic spontaneous urticaria was performed. Data on socio-demographic variables and disease activity, quality of life, sleep, sexual dysfunction, anxiety, depression and TDp were collected using validated question-naires. TDp was present in 28% (21/75) of the patients. Although TDp was not related to worse disease control, the presence of anxiety and depression was higher in patients with TDp. Regarding quality of life, TDp was associated with poorer quality of life and higher frequency of sleep disturbances. Prevalence of TDp in patients with chronic spontaneous urticaria is similar to that in the general population. It is associated with mood status disturbances and worse quality of life regardless of disease severity, especially in the emotional and psychological domains. This group of patients could benefit from additional psychological support as a complement to their medical treatment.

Chronic Spontaneous Urticaria (CSU) has been associated with patients’ poor quality of life. Despite being a chronic disease that could alter the quality of life of the people who live with patients, the potential burden on their cohabitants has not been studied to date. The aim of this study is to analyze the relationship between the patient’s quality of life, disease control, disease duration and family quality of life and the cohabitant’s mood disturbances, sexual dysfunction, type D personality and sleep quality. A cross-sectional study including patients suffering from CSU and their cohabitants was performed. Sociodemographic variables and disease activity, quality of life, sleep, sexual disfunction, anxiety, depression and type D personality were collected using validated questionnaires. Sixty-two subjects, 31 CSU patients and 31 cohabitants, were included in the study. Worse disease control and poorer quality of life in patients were associated with poorer family quality of life and higher rates of anxiety among the cohabitants (p < 0.05). Patients’ poor quality of life was associated with reduced sexual satisfaction among the cohabitants (p < 0.05). Long disease duration (>10 years) was associated with an increased prevalence of type D personality among the cohabitants (prevalence ratio: 2.59, CI 95% 1.03–7.21). CSU seems to have an impact on the quality of life of cohabitants, especially in terms of increased rates of anxiety, poorer quality of life and reduced sexual satisfaction. The prolonged course of the disease could be associated with the increased presence of non-adaptative personality traits.
