Sleep disturbances and asthma control: a real life study.

The objective of the present study was to investigate the level of asthma control in real life and the relationship between Asthma Control Test (ACT) scores and sleep disturbances. Patients on control visits for bronchial asthma were asked to complete the ACT questionnaire and to answer 5 questions about their sleep quality (S5). It was found that asthma control was unsatisfactory in 44%. In all ACT classes the level of asthma control appeared to be inversely related to the presence of sleep disturbances: patients with good control reported less frequent and less severe sleep disturbances than uncontrolled subjects. However, a significant percentage of subjects (11-20%) with total control of asthma still had sleep disturbances that resulted in an impaired quality of life. Therefore in any asthma case with sleep disturbances a broader investigation is required whether that impairment is actually a result of asthma or some other co-morbidity. Thus it would be useful if patients who reported sleep disturbances despite good/total control of asthma and rhinitis were managed with a holistic clinical approach and underwent nocturnal polysomnographic monitoring.

Chronic cough and QoL in allergic and respiratory diseases measured by a new specific validated tool-CCIQ.

Even though chronic cough (CC) is a bothersome symptom, only a small number of studies have evaluated its specific burden on health-related quality of life (HRQL). The aim of the present study was to assess how the presence of CC interferes with HRQL. A total of 95 outpatients were enrolled during medical consultation at our "Chronic Cough Center". A health status measure (SF-36) and a new HRQL questionnaire specific for CC (CCIQ) were administered before the initial visit. Compared to the reference sample, CC patients reported significantly lower scores in 5 of 8 SF-36 domains: Social functioning (t=10.292), Physical role limitation (t=9.667), Emotional role limitation (t=7.712), General health (t=5.154) and Vitality (t=4.426). The analysis of CCIQ scores showed a disability due to CC, independent of its etiology. The greatest disabilities were observed in the Social relationship (58.33) domain, followed by Sleep/Concentration (54.26), Mood (51.49) and Daily activities (47.69). Sleep, disturbing the partner, and irritability were the three outstanding aspects, affecting 80% of patients. These results show that CC has a high negative impact on HRQL, and they further suggest that the CCIQ is a useful tool for obtaining a global evaluation including its impact and therapeutic options.

A new tool to evaluate the impact of chronic urticaria on quality of life: chronic urticaria quality of life questionnaire (CU-QoL).

BACKGROUND: Health-related quality of Life in patients with chronic urticaria is evaluated by mean of generic instruments or questionnaire designed for skin diseases. No disease-specific tool is now available for the assessment of chronic urticaria impact from patients' viewpoint. OBJECTIVE: The aim of our study is to develop and validate a new questionnaire specifically designed for the assessment of quality of life in chronic urticaria (Chronic Urticaria Quality of Life Questionnaire -- CU-Q(2)oL). METHODS: In the development phase of CU-Q(2)oL an initial list of items of 37 items was compiled and given to 80 patients with chronic urticaria; the 23 most significant items were selected and converted into questions evaluating the answers on a Likert scale of five steps. The validation procedure involved 125 patients (86 F and 39 M) (age 42.17 +/- 9.24 years). RESULTS: Following a statistical analysis, CU-Q(2)oL showed a six-dimensional structure and good levels of internal consistency for the extracted factors: Pruritus (0.79), Swelling (0.65), Impact on life activities (0.83), Sleep problems (0.77), Looks (0.83) and Limits (0.74). In stable conditions CU-Q(2)oL showed a good reliability, ranged between 0.64 and 0.92. Responsiveness to clinical changes was accomplished. DISCUSSION: These results provide evidence that CU-Q(2)oL has specificity enough for being a valid tool for detecting the relative burden of CU on subjective wellbeing, and for obtaining a global evaluation both of CU impact and of treatments, taking into account the patient's point of view. The CU-Q(2)oL was easily and quickly filled up and well accepted by the patients.

A new tool to assess and monitor the burden of chronic cough on quality of life: Chronic Cough Impact Questionnaire.

INTRODUCTION: Chronic cough, one of the most frequent causes for a patient to consult a medical practitioner, limits the course of normal activities in everyday life of the patient affected (work, physical activities, social relations, night sleep). By now, there are few validated questionnaires for the evaluation of the impact of this symptom in the patient's quality of life (QoL). For this reason, we created a new questionnaire for the assessment of QoL in patients affected by chronic cough (Chronic Cough Impact Questionnaire, CCIQ). MATERIALS AND METHODS: In the development procedure of CCIQ an initial questionnaire of 40 items was compiled and given to a first pool of 170 patients, each coming to our attention because of chronic cough; then the 25 most significant items were detected and converted into questions evaluating the answers on a Likert scale of five steps. Consequently, this final questionnaire underwent a validation procedure to assess its construct validity, internal consistency, reliability, and responsiveness. 95 patients (44.2% F, 55.8% M) were evaluated (age 53.69 +/- 11.7 years). RESULTS: Following a statistical analysis, CCIQ showed a four-dimensional structure and good levels of internal consistency for the extracted factors: sleep/concentration (79.98), relationship (86.98), daily life impact (69.04), and mood (65.41). In stable conditions CCIQ showed a good reliability, ranged between 0.67 and 0.88. Responsiveness to clinical changes was accomplished. DISCUSSION: These results provide evidence that CCIQ has specificity enough for being a valid tool for detecting the relative burden of cough on subjective well-being, and for obtaining a global evaluation both of chronic cough impact and of treatments for it, taking into account the patient's point of view. The CCIQ was easily and quickly filled in by the patients while waiting, and it was accepted by the patients.
