Abstract
OBJECTIVES : National goals for improving asthma outcomes include decreasing emergency room utilization and increasing adherence to outpatient treatment guidelines. Few studies have examined the impact of substance use disorders on asthma treatment. The objective of this study was to describe correlations between substance use disorders and patterns of healthcare utilization for asthma care. METHODS : We performed a retrospective analysis of 1999 Medicaid claims for adults with asthma from 5 states. Adjusted odds of receiving asthma treatment in outpatient, inpatient, and emergency settings were calculated for patients with substance use disorder (SUD). RESULTS : Consistent patterns emerge demonstrating significantly lower odds of utilization of outpatient services for asthma in patients with SUD. A trend toward increased utilization of acute care resources was observed, with odds of emergency care for asthma significantly increased in New Jersey (odds ratio [OR], 1.14; 95% confidence interval [CI], 1-1.31) and Georgia (OR, 1.24; 95% CI, 1.04-1.48), and odds of inpatient care for asthma significantly increased in Georgia (OR, 1.42; 95% CI, 1.03-1.95). CONCLUSIONS : Substance use disorders are associated with decreased odds of receiving outpatient care and equivalent or increased odds of receiving emergency and inpatient care for asthma. Consequently, outpatient-based strategies to improve asthma care may have a very limited impact for this population. Identifying asthma patients with SUD in acute care settings and enhancing the care they receive in these settings may be necessary to improve adherence to treatment guidelines and decrease utilization in this population.

Iwata M, Ota KT, Duman RS. The inflammasome: pathways linking psychological stress, depression, and systemic illnesses. Brain Behav Immun 2013; 31:105-14.

Abstract
Stress is a common occurrence in everyday life and repeated or traumatic stress can be a precipitating factor for illnesses of the central nervous system, as well as peripheral organ systems. For example, severe or long-term psychological stress can not only induce depression, a leading illness worldwide, but can also cause psychosomatic diseases such as asthma and rheumatoid arthritis. Related key questions include how psychological stress influences both brain and peripheral systems, and what detection mechanisms underlie these effects? A clue is provided by the discovery of the pathways underlying the responses to host "danger" substances that cause systemic diseases, but can also contribute to depression. The inflammasome is a protein complex that can detect diverse danger signals and produce the accompanying immune-inflammatory reactions. Interestingly, the inflammasome can detect not only pathogen-associated molecules, but also cell damage-associated molecules such as ATP. Here, we propose a new inflammasome hypothesis of depression and related comorbid systemic illnesses. According to this hypothesis, the inflammasome is a central mediator by which psychological and physical stressors can contribute to the development of depression, and as well as a bridge to systemic diseases. This hypothesis includes an explanation for how psychological stress can influence systemic diseases, and conversely how systemic diseases can lead to psychiatric illnesses. The evidence suggests that the inflammasome may be a new target for the development of treatments for depression, as well as psychosomatic and somato-psycho diseases.

Utility of brief questionnaires of health-related quality of life (Airways Questionnaire 20 and Clinical COPD Questionnaire) to predict exacerbations in patients with asthma and COPD. Health Qual Life Outcomes 2013; 11:85. [PMID: 23706146 PMCID: PMC3701555 DOI: 10.1186/1477-7525-11-85] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2012] [Accepted: 05/21/2013] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND There is some evidence that quality of life measured by long disease-specific questionnaires may predict exacerbations in asthma and COPD, however brief quality of life tools, such as the Airways Questionnaire 20 (AQ20) or the Clinical COPD Questionnaire (CCQ), have not yet been evaluated as predictors of hospital exacerbations. OBJECTIVES To determine the ability of brief specific health-related quality of life (HRQoL) questionnaires (AQ20 and CCQ) to predict emergency department visits (ED) and hospitalizations in patients with asthma and COPD, and to compare them to longer disease-specific questionnaires, such as the St George´s Respiratory Questionnaire (SGRQ), the Chronic Respiratory Disease Questionnaire (CRQ) and the Asthma Quality of Life Questionnaire (AQLQ). METHODS We conducted a two-year prospective cohort study of 208 adult patients (108 asthma, 100 COPD). Baseline sociodemographic, clinical, functional and psychological variables were assessed. All patients completed the AQ20 and the SGRQ. COPD patients also completed the CCQ and the CRQ, while asthmatic patients completed the AQLQ. We registered all exacerbations that required ED or hospitalizations in the follow-up period. Differences between groups (zero ED visits or hospitalizations versus ≥ 1 ED visits or hospitalizations) were tested with Pearson´s X(2) or Fisher´s exact test for categorical variables, ANOVA for normally distributed continuous variables, and Mann-Whitney U test for non-normally distributed variables. Logistic regression analyses were performed to estimate the predictive ability of each HRQoL questionnaire. RESULTS In the first year of follow-up, the AQ20 scores predicted both ED visits (OR: 1.19; p = .004; AUC 0.723) and hospitalizations (OR: 1.21; p = .04; AUC 0.759) for asthma patients, and the CCQ emerged as independent predictor of ED visits in COPD patients (OR: 1.06; p = .036; AUC 0.651), after adjusting for sociodemographic, clinical, and psychological variables. Among the longer disease-specific questionnaires, only the AQLQ emerged as predictor of ED visits in asthma patients (OR: 0.9; p = .002; AUC 0.727). In the second year of follow-up, none of HRQoL questionnaires predicted exacerbations. CONCLUSIONS AQ20 predicts exacerbations in asthma and CCQ predicts ED visits in COPD in the first year of follow-up. Their predictive ability is similar to or even higher than that of longer disease-specific questionnaires.

Abstract
Asthma and mental health problems, such as depression, anxiety and behavior disorders, are common among youth and are significant sources of morbidity. There is a consistent association between asthma and anxiety/depression and a less consistent association between asthma and behavior disorders. Possible biological and psychological mechanisms may include inflammatory processes as well as the stress of having to live with a life-threatening condition. Future studies are warranted with longitudinal designs to establish temporality as well as measures of potential confounds. Biological and psychological measures would complement the longitudinal design to further establish causality. In addition, more information on the degree to which asthma and mental health have reciprocal influences on each other over time - and the mechanisms of these relationships - are needed in order to develop more effective intervention strategies to improve asthma control and mental health among those with both.

Abstract
OBJECTIVE Asthma patients know the benefits of exercise but often avoid physical activity because they are concerned that it will exacerbate asthma. The objective of this analysis was to assess longitudinal asthma status in 256 primary care patients in New York City enrolled in a trial to increase lifestyle physical activity. METHODS Patients were randomized to two protocols to increase physical activity during a period of 12 months. At enrollment, patients completed the Asthma Quality of Life Questionnaire (AQLQ) and the Asthma Control Questionnaire (ACQ) and received asthma self-management instruction through an evaluative test and workbook. Exercise and self-management were reinforced every 2 months. The AQLQ was repeated every 4 months and the ACQ was repeated at 12 months. RESULTS The mean age was 43 years and 75% were women. At 12 months there were clinically important increases in physical activity with no differences between groups; thus, data were pooled for asthma analyses. The enrollment AQLQ score was 5.0 ± 1.3 and increased to 5.9 ± 1.1 corresponding to a clinically important difference. Correlations between AQLQ and physical activity were approximately 0.35 (p < .0001) at each time point. In a mixed effects model, the variables associated with improvement in AQLQ scores over time were male sex, less severe asthma, not taking asthma maintenance medications, fewer depressive symptoms, and increased physical activity (all variables, p < .03). According to the ACQ, asthma was well controlled in 38% at enrollment and in 60% at 12 months (p < .0001). CONCLUSION With attention to self-management, increased physical activity did not compromise asthma control and was associated with improved asthma.

Abstract
BACKGROUND Factors that drive the use of urgent healthcare among people with chronic physical illness (i.e. long term conditions-LTCs) are poorly understood. We conducted a systematic review with meta analysis to examine the strength of association between depression and subsequent use of urgent healthcare among people with LTCs. METHODS Electronic searches of MEDLINE, EMBASE, PSYCINFO, CINAHL, the British Nursing Library and the Cochrane Library 2011 were conducted, supplemented by hand-searching bibliographies, citation tracing eligible studies and asking experts about relevant studies. Studies were eligible for inclusion if they: i)used prospective cohort design, ii)included patients with diabetes, asthma, chronic obstructive pulmonary disease or coronary heart disease, iii)used a standardised measure of depression, and iv)assessed urgent healthcare utilisation prospectively. Data on the subjects recruited, methods used and the association between depression and subsequent urgent healthcare utilisation were extracted from eligible studies. Odds ratios (ORs) were calculated for each study and pooled using random effects models. RESULTS 16 independent studies were identified. Pooled effects indicated that depression was associated with a 49% increase in the odds of urgent healthcare utilisation (OR=1.49, p<.0005). This effect was not significantly affected by publication bias or inclusion of studies of low quality. Effects were much smaller and non-significant among the 3 studies that controlled for other covariates, including severity of illness (OR=1.13, p=.31). CONCLUSIONS Depression was associated with increased urgent healthcare use, but not in the minority of studies that controlled for other covariates. This possibly suggests confounding, but the severity measures may themselves have been influenced by depression.

Abstract
The objective of this paper was to determine whether the presence of more vs. fewer anxious symptom features, at baseline, are associated with other clinical features and treatment outcomes in out-patients with major depressive disorder (MDD). This single-blind, randomized trial enrolled 665 MDD out-patients to compare the efficacy of two antidepressant medication combinations against escitalopram after 12-wk acute treatment and follow-up (total 28 wk). The sample was divided into those with greater (vs. fewer) anxiety features using the anxiety/somatization subscale of the baseline 17-item Hamilton Rating Scale for Depression. Baseline sociodemographic and clinical features, treatment features and outcomes compared these two groups. Overall, 74.7% of participants met the threshold for 'anxious features'. They were more likely to be female, have other concurrent anxiety disorders, more severe depression, more lethargic and melancholic features and poorer cognitive and physical functioning, quality of life and work and social adjustment. In acute treatment, participants with anxious features received comparatively higher doses of mirtazapine and venlafaxine and reported more side-effects. The groups with and without anxious features did not differ in treatment outcomes and side-effect burden. Despite being associated with a distinct clinical profile, baseline anxious features were not clinically useful in predicting acute treatment outcomes or differential treatment response.

Abstract
INTRODUCTION The quality of life (QOL) in persons with asthma is reduced and different factors such as demography, asthma severity and psychiatric comorbidity play an influential role. However, little is known about the interplay of these factors. OBJECTIVE To describe QOL in relation to asthma and analyse for the relative impact of asthma severity, psychiatric comorbidity, lifestyle (smoking and obesity) and demographic determinants on QOL in persons with asthma. METHODS One thousand one hundred sixty-one subjects from an earlier cohort with and without asthma were sent an asthma screening questionnaire and a generic QOL measuring instrument (15D). RESULTS Seven hundred seventy-eight valid responses (67%). QOL was significantly reduced in persons with asthma compared with controls (P = 0.001), almost on all domains of 15D. In the adjusted regression model, asthma severity, depression, female gender and smoking were associated with reduced QOL, suggesting that these factors play an independent role on lowering QOL. Depression did not inflate the relationship between asthma severity and worse QOL, suggesting that asthma severity plays an independent role on everyday life regardless of psychological state. CONCLUSION Asthma severity, psychiatric comorbidity, female gender and smoking were identified in this study to be major contributors to decreased QOL in asthmatics. Health professionals should be aware of this complex picture and take these factors into consideration when choosing the proper treatment of asthma patients. Asthma, asthma severity, epidemiology, psychiatric comorbidity, QOL.

Abstract
BACKGROUND Epidemiological studies have shown that asthma is positively associated with depression. Most of this evidence stems from individual studies conducted in Western populations (e.g. Europe, North America and Australia). It is still unclear whether such findings generalize to non-Western countries. To address this question, the present study investigated the association of asthma and wheezing with depression in a large multi-national sample. METHODS We used data from the 2002 World Health Survey. Participants reported physician-diagnosed asthma and attacks of wheezing within the past 12 months. Questions on depressive symptoms, their duration and persistence were used to define presence of a major depressive episode (MDE) within the past 12 months. ORs and 95% CIs were estimated by logistic regression for the entire sample, by continent (Australia, Europe, South America, Asia and Africa) and by country. Complete information was available for 57 countries. RESULTS Both asthma and wheezing were associated with MDE in the entire sample (OR=2.37, 95% CI=2.10-2.66 and OR=3.06, 95% CI=2.75-3.40, respectively). Similar associations were found for all continents with generally stronger ORs in South America, Asia and Africa for both asthma (ORs ≥ 1.8) and wheezing (ORs ≥ 2.8). On the country level, wheezing showed a consistent pattern of association with MDE. Similar patterns were found for asthma. CONCLUSIONS Despite a range of country differences that could affect the association of asthma with depression, such as access to health care, the results of this study indicate that the co-occurrence of asthma and depression is a universal phenomenon.

Abstract
BACKGROUND Depression is common in asthma and may be a risk factor for asthma-related morbidity and mortality. However, minimal data are available on depression treatment in asthma. Previously, we reported greater sustained depression remission and less oral corticosteroid use in asthma patients treated with citalopram. METHOD A 12-week randomized, double-blind, placebo-controlled, proof-of-concept trial of escitalopram was conducted in 26 outpatients with asthma requiring at least one course of oral corticosteroids in the prior 12 months and major depressive disorder (MDD) with baseline Hamilton Rating Scale for Depression (HAM-D) scores of ≥ 20. RESULTS Total evaluable sample (n = 25) showed significant baseline to exit reduction in HAM-D and Inventory of Depressive Symptomatology-Self Report (IDS-SR) scores, with no significant between-group differences, although the findings favored escitalopram. Depression remission on the HAM-D, from week 1 to exit, showed a trend (P = 0.06) favoring escitalopram. Relative risk for remission at week 12 was 6.5 with an estimated remission rate of 39.1% with escitalopram and 6.0% with placebo. Between-group differences in oral corticosteroid use were not significant. Changes in Asthma Control Questionnaire (ACQ) correlated significantly with changes in IDS-SR in the escitalopram, placebo, and combined sample groups (τ = 0.49-0.60, P < 0.05) and with changes in HAM-D only in placebo and combined groups (τ = 0.38-0.58, P < 0.05). CONCLUSIONS Medium effect sizes and a remission trend were observed favoring escitalopram over placebo on depression measures. Changes in self-reported depressive symptoms correlated with changes in asthma symptoms. A larger trial is needed to confirm the findings from this pilot study.

Abstract
BACKGROUND It is known that people who suffer from depression are more likely to have other physical illnesses, but the extent of the association between depression and non-psychiatric hospitalisation episodes has never been researched in great depth. We therefore aimed to investigate whether depressed middle-aged and older people were more likely to be hospitalised for causes other than mental illnesses, and whether the outcomes for this group of people were less favourable. METHODS #ENTITYSTARTX00026; FINDINGS Hospital events from 1995 to 2006 were obtained from the Dutch National Medical Register and linked to participants of the Longitudinal Aging Study Amsterdam (LASA). Linkage was accomplished in 97% of the LASA sample by matching gender, year of birth and postal code. Depression was measured at each wave point of the LASA study using the Centre for Epidemiologic Studies Depression (CES-D). Hospital outcomes including admission, length of stay, readmission and death while in hospital were recorded at 6, 12 and 24 months intervals after each LASA interview. Generalised Estimating Equation models were also used to investigate potential confounders. After 12 months, 14% of depressed people were hospitalised compared to 10% of non-depressed individuals. There was a 2-fold increase in deaths while in hospital amongst the depressed (0.8% vs 0.4%), who also had longer total length of stay (2.6 days vs 1.4 days). Chronic illnesses and functional limitations had major attenuating effects, but depression was found to be an independent risk factor for length of stay after full adjustment (OR = 1.33, 95% CI: 1.22-1.46 after 12 months). CONCLUSIONS Depression in middle and old age is associated with non-psychiatric hospitalisation, longer length of stay and higher mortality in clinical settings. Targeting of this high-risk group could reduce the financial, medical and social burden related to hospital admission.

Abstract
BACKGROUND "Asthma-related quality of life" (QOL) refers to the perceived impact that asthma has on the patient's QOL. OBJECTIVE National Institutes of Health institutes and other federal agencies convened an expert group to recommend standardized measures of the impact of asthma on QOL for use in future asthma clinical research. METHODS We reviewed published documentation regarding the development and psychometric evaluation; clinical research use since 2000; and extent to which the content of each existing QOL instrument provides a unique, reliable, and valid assessment of the intended construct. We classified instruments as core (required in future studies), supplemental (used according to the study's aims and standardized), or emerging (requiring validation and standardization). This work was discussed at an National Institutes of Health-organized workshop convened in March 2010 and finalized in September 2011. RESULTS Eleven instruments for adults and 6 for children were identified for review. None qualified as core instruments because they predominantly measured indicators of asthma control (symptoms and/or functional status); failed to provide a distinct, reliable score measuring all key dimensions of the intended construct; and/or lacked adequate psychometric data. CONCLUSIONS In the absence of existing instruments that meet the stated criteria, currently available instruments are classified as either supplemental or emerging. Research is strongly recommended to develop and evaluate instruments that provide a distinct, reliable measure of the patient's perception of the impact of asthma on all of the key dimensions of QOL, an important outcome that is not captured in other outcome measures.

Abstract
OBJECTIVES Understanding the events preceding emergency department (ED) asthma visits can guide patient education regarding managing exacerbations and seeking timely care. The objectives of this analysis were to assess time to seeking ED care, self-management of asthma exacerbations, and clinical status on presentation. METHODS A total of 296 patients was grouped according to time to seeking ED care: ≤1 day (22%), 2-5 days (44%), and >5 days (34%) and was compared for clinical and psychosocial characteristics. Asthma severity at presentation was obtained from patient report with the Asthma Control Questionnaire (ACQ) and the Asthma Quality of Life Questionnaire (AQLQ) and from physicians' ratings using decision to hospitalize as an indicator of worse status. RESULTS. Mean age was 44 years, 72% were women, 10% had been in the ED in the prior week, and 28% came to the ED by ambulance. Patients who waited longer were more likely to be older, have more depressive symptoms, and have been in the ED in the prior week. They also were more likely to have taken more medications, but they were not more likely to have visited or consulted their outpatient physicians. Patients who waited longer reported worse ACQ (p < .0001) and AQLQ (p = .0002) scores and were more likely to be hospitalized for the current exacerbation (odds ratio 1.9, 95% CI 1.1, 3.2, p = .03). CONCLUSIONS Patients who waited longer to come to the ED had worse asthma on presentation, had more functional limitations, and were more likely to be hospitalized. The ability to gauge severity of exacerbations and the use of the ED in a timely manner are important but often overlooked are self-management skills that patients should be taught.

Abstract
Prevalence of asthma and allergy has increased over the past 2-3 decades in Westernized countries. Despite increased understanding of the pathogenesis of asthma and allergic diseases, control of severe asthma is still difficult. Asthma is also associated with a high prevalence of anxiety, particularly in adolescents. There is no effective treatment for food allergy. Food allergy is often associated with severe and recalcitrant eczema. Novel approaches for treatment of asthma and food allergy and comorbid conditions are urgently needed. Traditional Chinese medicine, used in Asia for centuries, is beginning to play a role in Western healthcare. There is increasing scientific evidence supporting the use of traditional Chinese medicine for asthma treatment. Since 2005, several controlled clinical studies of "antiasthma" herbal remedies have been published. Among the herbal medicines, antiasthma herbal medicine intervention is the only antiasthma traditional Chinese medicine product that is a Food and Drug Administration investigational new drug that has entered clinical trials in the United States. Research into the effects and mechanisms of action of antiasthma herbal medicine intervention in animal models is actively being pursued. Research on traditional Chinese medicine herbal medicines for treating food allergy is rare. The herbal intervention Food Allergy Herbal Formula-2 is the only Food and Drug Administration botanical investigational new drug under investigation as a multiple food allergy therapy. This review article discusses promising traditional Chinese medicine interventions for asthma, food allergy, and comorbid conditions, and explores their possible mechanisms of action.

Abstract
BACKGROUND Subjects with asthma are more susceptible to psychological symptoms, but it is uncertain whether psychological symptoms are linked to future risk of asthma outcomes. OBJECTIVE To investigate the relationship between current psychological symptoms and future risk of asthma outcomes. METHODS We conducted a prospective cohort study with a 12-month follow-up period of 297 patients with asthma. Psychological symptoms, lung function, asthma control test, and Asthma Quality of Life Questionnaire at baseline were assessed. Asthma outcomes including exacerbations, unplanned visits, emergency visits, hospital admissions, intensive care unit admissions, and length of hospital stays were monitored monthly. The time to the first asthma outcomes was analyzed. Furthermore, the association between psychological symptoms and future risk of asthma outcomes was calculated as adjusted relative risk (RR) using logistic regression models. RESULTS The asthma patients were assigned to one of three groups: neither anxiety nor depression symptoms (NAD, n = 102), either anxiety or depression symptoms (A/D, n = 68), or anxiety and depression symptoms (AD, n = 120). Logistic regression models indicated that asthma patients in the AD group, but not the A/D group, had an increased adjusted RR for unplanned visits and emergency visits (RR = 2.33, 95% confidence interval (CI) = [1.50, 3.61]; and RR = 3.13, 95% CI = [1.90, 5.17], respectively). The time to the first asthma outcomes including exacerbations, unplanned visits, and emergency visits was shorter in patients with psychological symptoms than those without (all p < .001). CONCLUSION Current psychological symptoms, especially anxiety combined with depression, independently predict the future risk of asthma outcomes. Ting Zhou and Lan Wang contributed equally to this study.

Abstract
OBJECTIVE The objective was to assess the association between asthma and depressive symptoms (DS) and to evaluate the relationship between DS and risk factors [smoking, physical inactivity, body mass index (BMI) and sleep duration] in asthmatic individuals. METHODS We analyzed data from the Israeli National Health Interview Survey, conducted among 9509 participants aged ≥21 years in 2003-2004. Data on sociodemographic factors, chronic respiratory disorders, DS and risk factors were obtained through telephone interviews. DS were measured using Short Form 36 mental health items. Analyses were performed using multivariate logistic regression models. RESULTS A total of 393 participants (4.2%) reported chronic asthma in the 12 months previous to the interview. Of those, 37.4% had DS, compared with 21.8% of nonasthmatic participants [odds ratio (OR), 1.84; 95% confidence interval (CI), 1.47-2.30; P<.001]. DS in asthmatic individuals were significantly associated with physical inactivity [adjusted OR (AOR), 2.01; 95% CI, 1.12-3.61; P=.02], with smoking (AOR 1.80; 95% CI, 1.04-3.12; P=.04) and with less sleep (AOR, 1.81; 95% CI, 1.03-3.19; P=.04). DS in asthmatic participants were not associated with BMI. CONCLUSIONS DS are common in asthmatic individuals and are significantly associated with physical inactivity, with smoking and with less hours of sleep. Such health-related risk factors may impact on the course of asthma and on overall health.

Abstract
BACKGROUND This systematic review aims to investigate the association between comorbid mental disorders and quality of life (QoL) in patients with chronic medical diseases. METHODS Studies investigating adults with diabetes mellitus, coronary artery disease, asthma, chronic back pain and colorectal cancer were included. Two reviewers independently extracted data and assessed methodological criteria. Effect sizes for QoL scores were analyzed in random-effects meta-analyses. Subgroup and sensitivity analyses were conducted. RESULTS The database search identified 7,291 references and 65 primary studies were included. Medically ill persons with comorbid mental disorders showed a significantly decreased overall (d = -1.10; 95% CI = -1.34 to -0.86), physical (d = -0.64; 95% CI = -0.74 to -0.53) and psychosocial (d = -1.18; 95% CI = -1.42 to -0.95) QoL compared to persons without mental disorders. Subgroup analyses did not reveal significant differences between the examined medical diseases or mental disorders. CONCLUSION The review provides evidence of a substantially reduced psychosocial and physical QoL in medically ill patients with comorbid mental disorders. This patient-reported outcome highlights the importance of recognizing and treating comorbid mental disorders in the medically ill.

Health care costs in persons with asthma and comorbid mental disorders: a systematic review. Gen Hosp Psychiatry 2011; 33:443-53. [PMID: 21831446 DOI: 10.1016/j.genhosppsych.2011.06.013] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2011] [Revised: 06/28/2011] [Accepted: 06/28/2011] [Indexed: 01/02/2023]
Abstract
OBJECTIVE The aim of this study was to systematically review the impact of comorbid mental disorders on health care costs in adult persons with asthma. METHOD A comprehensive search for studies investigating adult persons (≥18 years) with asthma was conducted. All studies were included, which allowed a comparison of health care utilization and costs between asthma patients with mental disorders and asthma patients without. RESULTS The literature search revealed 1977 potentially relevant studies. Eighteen primary studies (20 publications) fulfilled the inclusion criteria. Mood disorders (n=14) and anxiety disorders (n=9) were studied most often. Increased rates of hospitalizations (odds ratio range, 0.9-6.1; n=7), emergency department visits (odds ratio range, 1.8-17.2; n=7) and general practitioner visits (standardized mean difference range, 0.1-1.1; n=6) were found in asthma patients with mental comorbidity. Indirect costs of work absence were investigated in two studies pointing in the same direction of increased costs. Evidence is sparse regarding other outcomes due to a lack of primary studies. CONCLUSION The present systematic review highlights a meaningful impact of comorbid mental disorders on health care utilization and costs in adult patients with asthma. Thus, psychodiagnostic routines and appropriate mental health treatments are needed to reduce health care costs in asthma care.

Abstract
OBJECTIVE To examine the association between clinical and socioeconomic variables and their influence on psychological and cost outcomes in patients with occupational asthma (OA). METHODS Longitudinal study of 60 subjects who claimed compensation for OA in Quebec. Besides clinical markers of asthma, quality of life (QOL), psychological distress (PD) measures, and an instrument to diagnose mental disorders were used. RESULTS The QOL and PD parameters had moderate correlations with clinical markers of OA. Asthma severity, employment, marital status, income, and the length of employment with the employer showed the strongest associations with QOL and PD. More-impaired QOL was associated with higher direct costs for compensation. CONCLUSION Impaired QOL and PD are frequent among subjects with OA receiving compensation and are associated with clinical markers of OA and socioeconomic factors.

Abstract
BACKGROUND AND OBJECTIVES Asthma and depression are common health problems in primary care. Evidence of a relationship between asthma and depression is conflicting. OBJECTIVES to determine 1. The incidence rate and incidence rate ratio of depression in primary care patients with asthma compared to those without asthma, and 2. The standardized mortality ratio of depressed compared to non-depressed patients with asthma. METHODS A historical cohort and nested case control study using data derived from the United Kingdom General Practice Research Database. PARTICIPANTS 11,275 incident cases of asthma recorded between 1/1/95 and 31/12/96 age, sex and practice matched with non-cases from the database (ratio 1:1) and followed up through the database for 10 years. 1,660 cases were matched by date of asthma diagnosis with 1,660 controls. MAIN OUTCOME MEASURES number of cases diagnosed with depression, the number of deaths over the study period. RESULTS The rate of depression in patients with asthma was 22.4/1,000 person years and without asthma 13.8 /1,000 person years. The incident rate ratio (adjusted for age, sex, practice, diabetes, cardiovascular disease, cerebrovascular disease, smoking) was 1.59 (95% CI 1.48-1.71). The increased rate of depression was not associated with asthma severity or oral corticosteroid use. It was associated with the number of consultations (odds ratio per visit 1.09; 95% CI 1.07-1.11). The age and sex adjusted standardized mortality ratio for depressed patients with asthma was 1.87 (95% CI: 1.54-2.27). CONCLUSIONS Asthma is associated with depression. This was not related to asthma severity or oral corticosteroid use but was related to service use. This suggests that a diagnosis of depression is related to health seeking behavior in patients with asthma. There is an increased mortality rate in depressed patients with asthma. The cause of this needs further exploration. Consideration should be given to case-finding for depression in this population.

Abstract
Previous studies have linked poor mental human health with environmental degradation, but none have assessed additional diseases that may co-exist with these mental disorders. In previous work, depression was found to be associated with a major form of environmental degradation; dryland salinity. However, little is known about diseases co-morbid with depression in this environmental setting. In rural Australia, dryland salinity is a major form of environmental degradation contributing widely to deterioration and non-viability of farmland. Using georeferenced health record data, Bayesian spatial methods were used to determine the relationship between dryland salinity and a range of human health outcomes. Initial modelling found an increased relative risk for asthma, suicide and ischaemic heart disease in relation to dryland salinity (adjusted for Indigenous and socio-economic status). However, in this follow-up study, a further evaluation of the role of co-morbidities in this population revealed that: (i) the presence of depression was consistently linked to residence in areas with high salinity and (ii) the association of asthma, suicide and heart disease with salinity was most likely attributable to the co-morbidity of the conditions with depression. Given the predicted increase in dryland salinity and the elevated relative risk of depression in impacted areas, the relative risk of the co-morbid conditions can be expected to increase in rural areas in the future, further adding to the burden of disease associated with environmental degradation.

Abstract
AIMS Individuals with asthma may be at increased risk of depression, but few studies have identified precursors to the onset of depression. The study goal was to identify risk factors for depression onset among a community-based sample of adults with asthma. METHODS Data were obtained from three telephone interviews conducted at 2-yearly intervals on a longitudinal cohort of adults with asthma (n=439). The Center for Epidemiologic Studies Depression scale (CESD) was used to measure depressive symptoms. Multiple regression analyses tested associations of sociodemographic and health-related variables with depression prevalence (cross-sectional analyses) and incident depression (longitudinal analyses). RESULTS 15% of subjects were classified as "depressed" (CESD> or =23) at each interview. Individuals depressed at baseline were more likely to drop out (OR=1.76 [95% CI 1.05, 2.96]). Low perceived control of asthma (measured with the Perceived Control of Asthma Questionnaire [PCAQ]) exhibited the most consistent association with depression. Lower PCAQ was cross-sectionally associated with depression (OR=0.51 per 0.5 SD difference in PCAQ [0.35, 0.75]). Onset of depression was noted in 38 individuals. Decrease in perceived control at follow-up was associated with depression onset (OR=7.47 [2.15, 26.01]). CONCLUSIONS Low perceived control of asthma predicted depression onset among adults with asthma. This risk factor may respond to self-management education.

Abstract
BACKGROUND Self-management education is a cornerstone of routine asthma care. OBJECTIVES To improve asthma knowledge and self-efficacy and to assess effects in patients with depressive symptoms. METHODS In a randomized trial, controls received asthma brochures and social support through frequent follow-up visits. Intervention patients made a contract to adopt a behavior to improve asthma and received a workbook, weekly reinforcements for 12 weeks, and frequent follow-up visits. Outcomes were Asthma Quality of Life Questionnaire (AQLQ) and 36-Item Short Form Health Survey (SF-36) scores and emergency department (ED) visits and hospitalizations for asthma. RESULTS Ninety patients were randomized to each group. Mean age was 43 years, 84% were women, and mean study time was 27 months. Intervention patients had more improvement in AQLQ scores at 5 months, but this difference was not sustained. For the entire period, AQLQ scores improved by a clinically important difference from 4.1 to a mean of 5.1 in both groups (P < .001) with no difference between groups (P = .91). In multivariate analysis, younger age, more education, better enrollment AQLQ score, more asthma self-efficacy and knowledge, and fewer depressive symptoms were associated with more improvement (P < .05 for all). Similar results were found for the SF-36. Thirty-one percent of patients had an ED visit, and 9% were hospitalized, with no differences between groups. In multivariate analysis, female sex, expecting to be cured of asthma, less asthma knowledge, and more depressive symptoms were associated with ED visits. Being in the intervention group attenuated the effects of depressive symptoms for all outcomes. CONCLUSIONS Quality of life improved in both groups, with particular benefit in intervention patients with depressive symptoms.

Abstract
OBJECTIVE To investigate the association between depressive symptoms, social support, and prevalent as well as incident asthma. Depressive symptoms and social support may affect the development of asthma. This relationship could be mediated by health behaviors and/or inflammatory processes. Evidence from prospective cohort studies on depressive symptoms and social support in relation to asthma risk in adults remains sparse. METHODS Between 1992 and 1995, a population-based sample of 5114 middle-aged adults completed questionnaires covering depressive symptoms, social support, self-reported asthma, and potential confounders. Among those alive in 2002/2003, 4010 (83%) were followed-up by questionnaires. Associations with prevalent and incident asthma were estimated by prevalence ratios (PR) and risk ratios (RR) along with corresponding 95% confidence intervals (CIs), using Poisson regression. PRs and RRs were adjusted for demographics, family history of asthma, smoking, alcohol consumption, body mass index, and physical exercise. RESULTS Cross-sectional analyses indicated that the prevalence of asthma was positively associated with depressive symptoms and inversely related to social support. Prospective analysis suggested a 24% increased risk of asthma with each 1-standard deviation increase in depressive symptoms (RR, 1.24; 95% CI, 1.02, 1.50), whereas the social support z score showed an inverse association with asthma incidence (RR, 0.71; 95% CI, 0.58, 0.88). Analyses with tertiles suggested similar, but nonsignificant, associations. Omitting health-related life-style variables from the multivariable models did not substantially alter these associations. CONCLUSIONS Risk of adult asthma was found to increase with depressive symptoms and to decrease with social support. These associations do not seem to be explained by health-related life-style factors.

Abstract
Interleukin (IL)-18 is a cytokine isolated as an important modulator of immune responses and subsequently shown to be pleiotropic. IL-18 and its receptors are expressed in the central nervous system (CNS) where they participate in neuroinflammatory/neurodegenerative processes but also influence homeostasis and behavior. Work on IL-18 null mice, the localization of the IL-18 receptor complex in neurons and the neuronal expression of decoy isoforms of the receptor subunits are beginning to reveal the complexity and the significance of the IL-18 system in the CNS. This review summarizes current knowledge on the central role of IL-18 in health and disease.

Abstract
BACKGROUND For millions of adults, effective control of asthma requires a regimen of care that may be compromised by psychological factors, such as anxiety and depression. This study estimated the prevalence and risk factors for serious psychological distress (SPD) and explored their relationship to health-related quality of life (HRQOL) among adults with asthma in the United States. METHODS We analyzed data from 186,738 adult respondents from the 2001-2007 US National Health Interview Survey. We calculated weighted average prevalence estimates of current asthma and SPD by demographic characteristics and health-related factors. We used logistic regression analysis to calculate odds ratios for factors that may have predicted asthma, SPD, and HRQOL. RESULTS From 2001 to 2007, the average annual prevalence of current asthma was 7.0% and the average prevalence of SPD was 3.0%. Among adults with asthma, the prevalence of SPD was 7.5% (95% CI, 7.0%-8.1%). A negative association between HRQOL and SPD was found for all adults, independent of asthma status. A similar pattern of risk factors predicted SPD and the co-occurrence of SPD and asthma, although adults with asthma who reported lower socioeconomic status, a history of smoking or alcohol use, and more comorbid chronic conditions had significantly higher odds of SPD. CONCLUSION This research suggests the importance of mental health screening for persons with asthma and the need for clinical and community-based interventions to target modifiable lifestyle factors that contribute to psychological distress and make asthma worse.

Abstract
BACKGROUND Different instruments have been developed to assess health-related quality of life (HRQL) in asthma patients. However, relatively few studies have assessed HRQL in asthma patients from a general population, and it is still unclear which instrument is most suitable. The purpose of this study was to compare HRQL in clinically verified asthmatics with subjects with respiratory symptoms without asthma and with subjects with no respiratory symptoms from a general population. The generic instrument Gothenburg Quality of Life (GQL) was used. A secondary aim was to study if GQL had any prognostic value in asthma. METHODS A cohort of three age groups in Sweden was investigated in 1990 using a respiratory questionnaire and GQL. The cohort consisted of 616 subjects with asthma, 488 subjects with respiratory symptoms but no asthma, and 347 subjects without respiratory symptoms. The participants were also investigated by spirometry and allergy testing. In a follow-up study, subjects were identified who had persistent and improved asthma. RESULTS The prevalence of 28 of the 30 common symptoms in GQL was significantly increased (p < 0.001) in subjects with asthma as compared to non-asthmatics. All symptoms in the domains heart and lung, head, musculoskeletal, tension, and depression were significantly increased among the asthmatics. The asthmatics also rated their physical well-being lower (p < 0.001) than subjects with no respiratory symptoms. Subjects with persistent asthma had a significantly higher prevalence of 7 of the 30 symptoms and lower social well-being than subjects showing improvement in asthma during the follow-up. All differences remained significant after adjusting for age, sex, and smoking habits. CONCLUSION Subjects with asthma had different symptom-profiles compared to those of non-asthmatics, with a higher prevalence of both respiratory and non-respiratory symptoms. Asthma is also a disease that is related to low well-being. The use of quality-of-life questionnaires such as the GQL may provide useful information for evaluating the non-respiratory aspects of asthma as well as for assessing the impact of disease on health status and well-being.

Abstract
BACKGROUND With the expanding effort to provide guidelines-based therapy to adolescents with asthma, attention must be directed to evaluating which factors predict future asthma control when guidelines-based management is applied. OBJECTIVE We evaluated the role of fraction of exhaled nitric oxide in parts per billion, markers of allergic sensitization, airway inflammation, and measures of asthma severity in determining future risk of asthma symptoms and exacerbations in adolescents and young adults participating in the Asthma Control Evaluation study. METHODS Five hundred forty-six inner-city residents, ages 12 through 20 years, with persistent asthma were extensively evaluated at study entry for predictors of future symptoms and exacerbations over the subsequent 46 weeks, during which guidelines-based, optimal asthma management was offered. Baseline measurements included fraction of exhaled nitric oxide in parts per billion, total IgE, allergen-specific IgE, allergen skin test reactivity, asthma symptoms, lung function, peripheral blood eosinophils, and, for a subset, airway hyperresponsiveness and sputum eosinophils. RESULTS The baseline characteristics we examined accounted for only a small portion of the variance for future maximum symptom days and exacerbations--11.4% and 12.6%, respectively. Future exacerbations were somewhat predicted by asthma symptoms, albuterol use, previous exacerbations, and lung function, whereas maximum symptom days were predicted, also to a modest extent, by symptoms, albuterol use, and previous exacerbations, but not lung function. CONCLUSION Our findings demonstrate that the usual predictors of future disease activity have little predictive power when applied to a highly adherent population with persistent asthma that is receiving guidelines-based care. Thus, new predictors need to be identified that will be able to measure the continued fluctuation of disease that persists in highly adherent, well-treated populations such as the one studied.

Abstract
PURPOSE OF REVIEW To summarize recent findings on the psychological impact of occupational asthma, on the basis of a review of medical and psychological literature published between 1998 and 2008. For the purposes of this review, 'psychological impacts' are defined as the experience of psychological stress or distress, which refers to the experience of negative emotions (e.g., anxiety and sadness/depression). When severe and chronic, psychological distress may reach clinical levels and is referred to as a 'psychiatric disorder', which is a clinical diagnosis based on established diagnostic criteria. RECENT FINDINGS Only one original article assessing psychological impacts has been published in the past 10 years (in 2007). Levels of psychological distress (i.e., depression, anxiety, and cognitive dysfunction) were all in the clinical range, and rates of anxiety disorders and dysthymia (a chronic form of depression) affected approximately 35 and 23% of patients, respectively. SUMMARY The paucity of available literature indicates that the study of psychological factors associated with occupational asthma is still in its infancy. Though preliminary and in need of replication, the only published study to date suggests that patients with occupational asthma may be highly anxious and many are chronically depressed, a finding that is consistent with previous studies with nonoccupational asthmatics. The established link between psychological factors (e.g., depression and anxiety) and nonoccupational asthma suggests that future studies are desperately needed to more comprehensively assess the scope and severity of the psychological burden of this disease.

Abstract
Asthma is a highly prevalent chronic respiratory disease affecting 300 million people world-wide. A significant fraction of the cost and morbidity of asthma derives from acute care for asthma exacerbations. In the United States alone, there are approximately 15 million outpatient visits, 2 million emergency room visits, and 500,000 hospitalizations each year for management of acute asthma. Common respiratory viruses, especially rhinoviruses, cause the majority of exacerbations in children and adults. Infection of airway epithelial cells with rhinovirus causes the release of pro-inflammatory cytokines and chemokines, as well as recruitment of inflammatory cells, particularly neutrophils, lymphocytes, and eosinophils. The host response to viral infection is likely to influence susceptibility to asthma exacerbation. Having had at least one exacerbation is an important risk factor for recurrent exacerbations suggesting an 'exacerbation-prone' subset of asthmatics. Factors underlying the 'exacerbation-prone' phenotype are incompletely understood but include extrinsic factors: cigarette smoking, medication non-compliance, psychosocial factors, and co-morbidities such as gastroesophageal reflux disease, rhinosinusitis, obesity, and intolerance to non-steroidal anti-inflammatory medications; as well as intrinsic factors such as deficient epithelial cell production of the anti-viral type I interferons (IFN-alpha and IFN-beta). A better understanding of the biologic mechanisms of host susceptibility to recurrent exacerbations will be important for developing more effective preventions and treatments aimed at reducing the significant cost and morbidity associated with this important global health problem.

Health-related quality of life predicts onset of asthma in a longitudinal population study. Respir Med 2008; 103:194-200.

Abstract
BACKGROUND Health-related quality of life (HRQL) has been increasingly used as an outcome measure in asthma, but less is known about the prognostic implication of low health-related quality of life. The purpose of this study was to investigate if a set of quality of life measures could predict onset of asthma. METHODS In the baseline study 391 subjects without asthma answered a respiratory questionnaire and the Gothenburg Quality of Life (GQL) instrument in 1990. The GQL questionnaire included two parts: (1) the prevalence of HRQL-related symptoms and (2) well-being scores for physical, mental and social dimensions. The participants were also investigated with spirometry and allergy testing. In 2003, the same respiratory questionnaire that had been used in 1990 was sent. There were 290 responders, of whom 22 subjects had developed asthma. RESULTS Participants who had developed asthma by the follow-up had a higher prevalence of sleep disturbances (30% vs. 10%), problems with chest pain (16% vs. 2%), depression (40% vs. 20%) difficulty relaxing (40% vs. 13%) and constipation (25% vs. 2%) at baseline than participants who did not develop asthma (p<0.05). Subjects who developed asthma also scored significantly lower on well-being variables as sleep, energy, mood, patience, memory, appetite, fitness and sense of appreciation outside home. These differences remained after adjusting for age, sex, smoking habits, asthma heredity, socioeconomic groups and building dampness. CONCLUSION Participants with low health-related quality of life at baseline were more likely to report having developed asthma 12 years later.

Abstract
OBJECTIVES To investigate a) whether childhood adversity predicts adult-onset asthma; b) whether early-onset depressive/anxiety disorders predict adult-onset asthma; and c) whether childhood adversity and early-onset depressive/anxiety disorders predict adult-onset asthma independently of each other. Previous research has suggested, but not established, that childhood adversity may predict adult-onset asthma and, moreover, that the association between mental disorders and asthma may be a function of shared risk factors, such as childhood adversity. METHODS Ten cross-sectional population surveys of household-residing adults (>18 years, n = 18,303) assessed mental disorders with the Composite International Diagnostic Interview (CIDI 3.0) as part of the World Mental Health surveys. Assessment of a range of childhood family adversities was included. Asthma was ascertained by self-report of lifetime diagnosis and age of diagnosis. Survival analyses calculated hazard ratios (HRs) for risk of adult-onset (>age 20 years) asthma as a function of number and type of childhood adversities and early-onset (<age 21 years) depressive and anxiety disorders, adjusting for current age, sex, country, education, and current smoking. RESULTS Childhood adversities predicted adult-onset asthma with risk increasing with the number of adversities experienced (HRs = 1.49-1.71). Early-onset depressive and anxiety disorders also predicted adult-onset asthma (HRs = 1.67-2.11). Childhood adversities and early-onset depressive and anxiety disorders both predicted adult-onset asthma after mutual adjustment (HRs = 1.43-1.91). CONCLUSIONS Childhood adversities and early-onset depressive/anxiety disorders independently predict adult-onset asthma, suggesting that the mental disorder-asthma relationship is not a function of a shared background of childhood adversity.

Abstract
OBJECTIVES Asthma is a frequent and serious chronic respiratory disease which is sometimes fatal. It involves all ages and all social subclasses. The goal of our study was to determine the demography of asthma in a low socio-economic community in Lebanon and to describe its association with various epidemiologic factors. MATERIALS AND METHODS The computerized data of 44.814 patients of a nongovernmental organization (Hariri Foundation), in Lebanon were reviewed. Asthmatic patients diagnosed by a health professional on the basis of medical criteria during the period from January 2003 to June 2005 were included in the analysis. The socio-economic characteristics of this population were retrieved and their geographical distributions were depicted. The study focused on the association of asthma with cutaneous and ocular allergies, depression, obesity and alcohol consumption. RESULTS The majority of asthmatic patients (75%) belonged to a low socio-economic environment with a salary lower than $200 per month. 31% were illiterate. 583 (1.3%) of patients on the database were asthmatic. The rate in children was higher (2.08%) than in adults (1.09%). The majority of asthma occurred among subjects from Bekaa valley and South Lebanon. Asthma was associated more strongly with being an ex-smoker (OR 4.37; 95% CI 2.38, 8.02) than being a current smoker (OR 1.44; 95% CI 1.11, 1.87). A significant and strong association was found with depression (OR 25.6; 95% CI 3.32, 197.6), obesity (OR 4.09, 95% CI 1.31, 12.73) and with regular alcohol consumption (OR 11.78; 95% CI 1.55, 89.44). CONCLUSION This study describes the association of asthma in this population with low socio-economic status. By defining the demographic characteristics of the asthma population the Ministry of Health and the medical organizations concerned should be better able to manage the condition. This study confirms, in a Lebanese population, the epidemiological associations described in other populations around the world.

Abstract
BACKGROUND Mortality risk in adult asthma is poorly understood, especially the interplay among race, disease severity, and health care access. OBJECTIVE To examine mortality risk factors in adult asthma. METHODS In a prospective cohort study of 865 adults with severe asthma in a closed-panel managed care organization, we used structured interviews to evaluate baseline sociodemographics, asthma history, and health status. Patients were followed up until death or the end of the study (mean, 2 years). We used Cox proportional hazards regression to evaluate the impact of sociodemographics, cigarette smoking, and validated measures of perceived asthma control, physical health status, and severity of asthma on the risk of death. RESULTS We confirmed 123 deaths (mortality rate, 6.7 per 100 person-years). In an analysis adjusted for sociodemographics and tobacco history, higher severity-of-asthma scores (hazard ratio [HR], 1.11 per 0.5-SD increase in severity-of-asthma score; 95% confidence interval [CI], 1.01-1.23) and lower perceived asthma control scores (HR, 0.91 per 0.5-SD increase in perceived asthma control score; 95% CI, 0.83-0.99) were each associated with risk of all-cause mortality. In the same adjusted analysis, African American race was not associated with increased mortality risk relative to white race (HR, 0.64; 95% CI, 0.36-1.14). CONCLUSIONS In a large managed care organization in which access to care is unlikely to vary widely, greater severity-of-asthma scores and poorer perceived asthma control scores are each associated with increased mortality risk in adults with severe asthma, but African American patients are not at increased risk for death relative to white patients.

Abstract
We investigated whether perceived neighborhood problems (NP) predicted changes over a 2-year period in asthma-specific quality of life (QOL), physical functioning (PF), and depressive symptomology (DEP) in a longitudinal cohort of 340 adults with asthma. There is a threshold and plateau effect between NP and PF, such that NP do not affect changes in PF until the problems reach the level of Quartile 3. People who had NP scores in Quartile 3 had lower PF compared to people who reported NP in Quartiles 1 or 2 (mean difference -3.09). High NP also predicted over two-fold odds of high DEP (Center for Epidemiological Studies Depression [CES-D] score > or = 16) at follow-up (odds ratio=2.34; 95% confidence interval: 1.09-5.00). NP did not predict decline in QOL. Analyses adjusted for demographics, asthma severity, and baseline value of the health outcome.

Abstract
BACKGROUND Negative affect including depression is known to be associated with asthma control, but whether and how it influences control in children with asthma is not understood. OBJECTIVE The objective of this investigation was to evaluate whether negative affect and medication nonadherence each predict decreased symptom control, and whether the relationship between negative affect and disease control is explained by children's adherence to asthma medications. METHODS Participants included 104 children 8 to 18 years old being treated with an inhaled corticosteroid delivered by metered-dose inhaler for asthma diagnosed by their health care providers. Children and parents independently rated asthma symptoms and completed questionnaires assessing sad and anxious affect. Electronic devices were attached to each participant's metered-dose inhaler to measure adherence. At study completion, records were collected to confirm reports of health events. RESULTS Both child and parent negative affect scores predicted symptom scores, whether reported by child or parent, and child negative affect scores predicted school absence because of asthma. In a lagged analysis taking into account time sequence, medication adherence predicted prednisone bursts but not subjective symptom scores. Nonadherence did not explain the relationship between negative affect and symptom scores, but parent negative affect predicted prednisone bursts even when controlling for level of adherence. CONCLUSION Although both negative affect and adherence were predictive of asthma control, the relationship of each to asthma control was distinctly different. Accuracy of symptom perception may be influenced by patient and parent affect characteristics.

Abstract
BACKGROUND To our knowledge, the use of psychotropic medications (antidepressant, anxiolytic, and hypnotic agents) in patients with asthma has not been extensively explored. OBJECTIVE To identify factors associated with the use of these medications in patients with asthma. METHODS Regular customers (aged 18-50 years) of 348 pharmacies in 9 French regions were consecutively recruited from November 2003 to June 2004. Patients with a prescription for an asthma medication were included. Patients completed a questionnaire, complemented by the computerized records of their therapy dispensed in the past 12 months. Asthma control was measured with the Asthma Control Test. RESULTS Among 886 patients (mean age, 37.4 years; 55.0% female), during the 12 months before the survey, the proportions who received at least 1 U of anxiolytic, antidepressant, and hypnotic agents were 25.6%, 13.7%, and 13.0%, respectively. Higher dispensing levels of antidepressant, anxiolytic, and hypnotic agents were observed with decreasing asthma control (P < .001 for each drug class). Other correlates of receiving any of these classes included older age, female sex, smoking status, and dispensing of antireflux treatment (P < .001 for all). These results were confirmed in multivariate analyses. CONCLUSIONS Psychotropic drugs were commonly dispensed to patients with asthma, and correlates of receiving these drugs were identified in this population. The high use of psychotropic medication, particularly in patients with poorly controlled asthma, is of concern.

Abstract
Correctly identifying asthma patients who need treatment for depression is part of comprehensive care. The objective of this study was to compare the prevalence of depressive symptoms measured by the short-form Center for Epidemiologic Studies Depression Scale (CESD-SF), which measures somatic and psychological symptoms, with the original and short-form Geriatric Depression Scale (GDS and GDS-SF), which measure only psychological symptoms. In total, 257 asthma patients (mean age 42 years, 75% women) completed the GDS (score range 0-30, positive screen > or = 11) and the CESD-SF (score range 0-30, positive screen > or = 10). The performance of each scale was compared to clinical diagnoses of depressive disorders reported by physicians using a skill score analysis. Twenty percent of patients had GDS scores > or = 11 and 32% had CESD-SF scores > or = 10. The somatic symptom of restless sleep was the most common CESD-SF symptom and the symptom that contributed most to the total score. The GDS had a skill score of +.16 (+1 = maximum possible, 0 = best guess) and the CESD-SF had a skill score of -.02 compared to physician-reported depressive disorders. Similar results were found for the GDS-SF. Thus, more patients had a positive CESD-SF screen, which was attributable mostly to a somatic sleep symptom that overlaps with asthma symptoms, and the GDS was more consistent with physicians' reports of depressive disorders.

Abstract
BACKGROUND Psychological factors such as anxiety and depression are increasingly being recognized as influencing the onset and course of asthma. METHODS We obtained Patient Health Questionnaire 8 depression data from 41 states and territories using the 2006 Behavioral Risk Factor Surveillance System. Heath risk behaviors, social and emotional support, life satisfaction, disability, and four health-related quality-of-life (HRQOL) questions were available for all states and territories (n = 18,856 with asthma). Five additional HRQOL questions were asked in three states (n = 1345 persons with asthma), and questions assessing asthma control were available for nine states (n = 3943 persons with asthma). RESULTS Persons with asthma were significantly more likely than those without asthma to have current depression (19.4% vs. 7.7%), a lifetime diagnosis of depression (30.6% vs. 14.4%), and anxiety (23.5% vs. 10.2%). For most domains examined, there was a dose-response relationship between level of depression severity and mean number of days of impaired HRQOL in the past 30 days, as well as an increased prevalence of life dissatisfaction, inadequate social support, disability, and risk behaviors, such as smoking, physical inactivity, and obesity, among those with asthma. Moreover, depression and anxiety were associated with a decreased level of asthma control, including more visits to the doctor or emergency room, inability to do usual activities, and more days of symptoms compared to those without depression or anxiety. CONCLUSION This research indicates that a multidimensional, integrative approach to health care should be considered when assessing patients with asthma.

Abstract
BACKGROUND Depressive conditions in asthma patients have been described mostly from patient reports and less often from physician reports. While patient reports can encompass multiple symptoms, physician assessments can attribute symptoms to a mental health etiology. Our objectives were to identify associations between patient- and physician-reported depressive conditions and asthma severity and control. METHODS Patient-reported depressive symptoms were obtained using the Geriatric Depression Scale (GDS) [possible score 0 to 30; higher score indicates more depressive symptoms]. Patients were categorized as having a physician-reported depressive disorder if they had the following: a diagnosis of depression, depressive symptoms described in medical charts, or were prescribed antidepressants at doses used to treat depression. Patients also completed the Severity of Asthma Scale (SOA) [possible score 0 to 28; higher score indicates more severe] and the Asthma Control Questionnaire (ACQ) [possible score 0 to 6; higher score indicates worse control]. RESULTS Two hundred fifty-seven patients were included in this analysis (mean age, 42 years; 75% women). Mean SOA and ACQ (+/- SD) scores were 5.9 +/- 4.2 and 1.4 +/- 1.2, respectively; and mean GDS score was 6.3 +/- 6.4. After adjusting for age, sex, race, Latino ethnicity, education, medication adherence, body mass index, and smoking status, patient-reported depressive symptoms were associated with asthma severity (p = 0.007) and with asthma control (p = 0.0007). In contrast, physician-reported depressive disorders were associated with asthma severity (p = 0.04) but not with asthma control (p = 0.22) after adjusting for covariates. CONCLUSIONS Physician- and patient-reported depressive conditions were associated with asthma severity. In contrast, patient-reported depressive symptoms were more closely associated with asthma control than were physician-reported depressive disorders. Identifying associations between depressive conditions and asthma severity and control is necessary to concurrently treat these conditions in this population.

Abstract
BACKGROUND A convincing body of literature links obesity with a higher risk for developing adult-onset asthma. The impact of obesity on asthma severity among adults with pre-existing asthma, however, is less clear. METHODS AND PROCEDURES In a prospective cohort study of 843 adults with severe asthma, we studied the impact of BMI on asthma health status. RESULTS The prevalence of obesity and overweight were 44% (95% confidence interval (CI) 41-47%) and 28% (95% CI 25-32%). The obese BMI group was associated with a higher risk for daily or near daily asthma symptoms than was the normal BMI group (odds ratio (OR) 1.81; 95% CI 1.10-2.96). Compared to the normal BMI group, generic physical health status was worse in the overweight (mean score decrement -2.42 points; 95% CI -4.39 to -0.45) and the obese groups (-6.31 points; 95% CI -8.14 to -4.49). Asthma-specific quality of life was worse in the underweight (mean score increment 8.66 points; 95% CI 2.53-14.8) and obese groups (4.51 points; 95% CI 2.21-6.81), compared to those with normal BMI. Obese persons also had a higher number of restricted activity days that past month (5.05 days; 95% CI 2.90-7.19 days). DISCUSSION It appears that obesity has a substantive negative effect on health status among adults with asthma. Further work is needed to clarify the precise mechanisms. Clinicians should counsel dietary modification and weight loss for their overweight and obese patients with asthma.

Abstract
BACKGROUND Depression and risk behaviors occur often in adolescents in the United States, but their frequency in youth with asthma is not well documented. OBJECTIVE To establish rates of and associations between depression and substance use in youth with asthma. METHODS The Centers for Disease Control and Prevention conducted the 2005 Youth Risk Behavior Survey with 13,917 students in grades 9 to 12 from 159 high schools in 40 states, producing a nationally representative distribution of students by grade, sex, and race/ethnicity. The Youth Risk Behavior Survey documents self-reported suicide intent and health risk behaviors, including use of tobacco, marijuana, alcohol, and cocaine. RESULTS In 720 adolescents reporting current asthma (5.2% of the total sample), depression symptoms, cigarette smoking, and cocaine use occurred more frequently than in youth without asthma. Substance use increased with depression; of youth with asthma reporting suicidal ideation, 40% had smoked cigarettes, 67% had smoked marijuana, 37% had engaged in binge drinking, and 12% had used cocaine in the past 30 days. Overall odds ratios for substance abuse in the group with asthma were not altered when controlling for age, sex, and race, although odds ratios for specific risk behaviors in those with asthma varied slightly within age, sex, and race groups. CONCLUSIONS National rates of depression and associated risk behaviors in youth with asthma have not been previously reported, indicate a need to screen adolescents with asthma for depression, and suggest that risk behaviors in this population may signal heightened need for intervention.

Abstract
BACKGROUND More than 40% of people born with cystic fibrosis (CF) now reach adulthood. Greater attention is being focused on improving their health-related quality of life (HRQoL). While markers of disease severity such as lung function are only modestly associated with HRQoL, in other chronic illnesses depression is an important correlate. The objective of this study was to evaluate the relationships among lung function (ie, FEV(1) percent predicted), depressive symptoms, and HRQoL among adults with CF. METHODS Seventy-six adults with CF completed a mail-based survey. The Beck Depression Inventory and the Cystic Fibrosis Questionnaire were used to assess depressive symptoms and HRQoL, respectively. Values for FEV(1) percent predicted were abstracted from the medical record. RESULTS Thirty percent of participants screened positive for depressive symptoms. Depressive symptoms and lung function were inversely correlated (rho = -0.25; p < .05). Correlations between depressive symptoms and HRQoL were maintained after stratifying by lung function. In the absence of depressive symptoms, those patients with good lung function (ie, FEV(1), > 70% predicted) reported better physical HRQoL than those with poor lung function. Participants with both depressive symptoms and poor lung function reported significantly worse HRQoL on all domains than participants without depressive symptoms regardless of lung function status. CONCLUSIONS Depressive symptoms are prevalent among adults with CF and are associated with poorer HRQoL even after controlling for lung function. These results suggest that screening for and treating depression is important and may potentially improve HRQoL among patients with CF.

Abstract
BACKGROUND Case series and case-control studies have shown high rates of psychosocial and behavioural risk factors amongst patients admitted to hospital with severe asthma. General population studies have shown associations between psychosocial factors and prevalent asthma but few have investigated incident asthma outcomes. METHODS Data on psychosocial factors and asthma hospital admissions were available for 20 854 participants, aged 41-80 years, in the Norfolk cohort of the European Prospective Investigation into Cancer study. Postal assessments included details of physical functioning, mood disorder history, social adversity and social support. RESULTS A total of 686 asthma hospital admissions were recorded. Psychosocial factors present at baseline, including current mood disorders, adverse circumstances in childhood, the impact of life events experienced during adulthood and negative perceived support from a close confidant, were associated with increased rates of hospital admission independent of age, sex, indicators of socio-economic status, physical functional health, and obesity. Restricted to those participants who reported lifetime doctor-diagnosed asthma at baseline, the reported impact of adverse life events experienced in adulthood, and both confiding and negative aspects of support quality, were associated with asthma hospital admission. The magnitude of these associations was comparable to those involving indicators of socio-economic status and physical health. CONCLUSIONS These results show that psychosocial factors are associated with incident asthma hospital admissions and highlight the potential importance of taking account of psychosocial factors, including availability and quality of support networks, in guiding long-term asthma management.

Abstract
BACKGROUND Primary care patients with anxiety and depression often describe multiple physical symptoms, but no systematic review has studied the effect of anxiety and depressive comorbidity in patients with chronic medical illnesses. METHODS MEDLINE databases were searched from 1966 through 2006 using the combined search terms diabetes, coronary artery disease (CAD), congestive heart failure (CHF), asthma, COPD, osteoarthritis (OA), rheumatoid arthritis (RA), with depression, anxiety and symptoms. Cross-sectional and longitudinal studies with >100 patients were included as were all randomized controlled trials that measure the impact of improving anxiety and depressive symptoms on medical symptom outcomes. RESULTS Thirty-one studies involving 16,922 patients met our inclusion criteria. Patients with chronic medical illness and comorbid depression or anxiety compared to those with chronic medical illness alone reported significantly higher numbers of medical symptoms when controlling for severity of medical disorder. Across the four categories of common medical disorders examined (diabetes, pulmonary disease, heart disease, arthritis), somatic symptoms were at least as strongly associated with depression and anxiety as were objective physiologic measures. Two treatment studies also showed that improvement in depression outcome was associated with decreased somatic symptoms without improvement in physiologic measures. CONCLUSIONS Accurate diagnosis of comorbid depressive and anxiety disorders in patients with chronic medical illness is essential in understanding the cause and in optimizing the management of somatic symptom burden.

Abstract
OBJECTIVE Our objectives were (a) to determine which common mental disorders are associated with asthma in the general population after controlling for age and sex, and (b) to assess whether the associations of mental disorders with asthma are consistent across diverse countries. METHOD Eighteen population surveys of household-residing adults were carried out in 17 countries (N=85,088). Mental disorders were assessed with the Composite International Diagnostic Interview 3.0, a fully structured diagnostic interview. The disorders considered here are 12-month anxiety disorders (generalized anxiety disorder, panic disorder/agoraphobia, posttraumatic stress disorder and social phobia), depressive disorders (dysthymia and major depressive disorder) and alcohol use disorders (abuse and dependence). Asthma was ascertained by self-reports of lifetime diagnosis among a subsample (n=42,697). RESULTS Pooled estimates of age-adjusted and sex-adjusted odds of mental disorders among persons with asthma relative to those without asthma were 1.6 [95% confidence interval (95% CI)=1.4, 1.8] for depressive disorders, 1.5 (95% CI=1.4, 1.7) for anxiety disorders and 1.7 (95% CI=1.4, 2.1) for alcohol use disorders. CONCLUSION This first cross-national study of the relationship between asthma and mental disorders confirms that a range of common mental disorders occurs with greater frequency among persons with asthma. These results attest to the importance of clinicians in diverse settings being alert to the co-occurrence of these conditions.

Abstract
PURPOSE We aimed to elucidate the prevalence of and risk factors for work disability in severe adult asthma and to evaluate the impact of work disability on downstream health outcomes. METHODS We used data from a prospective cohort study of 465 adults with severe asthma. Structured telephone interviews ascertained asthma status and employment history. A job exposure matrix (JEM) was used to characterize the likelihood of workplace exposure to "asthmagens." RESULTS The prevalence of asthma-related complete work disability was 14% among working-age adults with severe asthma (95% confidence interval, 11%-18%). Among those who were currently employed, the prevalence of partial work disability was 38% (95% confidence interval, 31%-45%). Sociodemographic (P = .027) and medical factors (P = .020) were related to the risk of complete work disability. Both sociodemographic characteristics (P = .06) and work exposures based on the JEM (P = .012) were related to partial work disability. In additional models, poorer asthma severity, physical health status, and mental health status were all associated with a higher risk of complete and partial work disability. CONCLUSIONS Work disability is common among adults with severe asthma. There are three sets of risk factors for work disability that are potentially modifiable: smoking, workplace exposures, and asthma severity.

Abstract
INTRODUCTION Demographic factors, symptom severity, and psychopathology, in particular anxiety and depression, are known to influence health care use and quality of life in asthma. Because depression and anxiety are typically correlated, we sought to explore whether depression specifically is associated with health care utilization and quality of life when effects of anxiety are controlled for. METHOD In a cross-sectional questionnaire study, 88 asthma patients (46 women; age range 27-70 years) reported on symptoms and treatment of their disease, as well as anxiety and depression (Hospital Anxiety and Depression Scale, HADS), general quality of life (Short Form 12 Health Survey Questionnaire, SF-12) and asthmatic-specific quality of life (Living with Asthma, LAQ). RESULTS While no considerable associations between anxiety and health care use were found, the associations between higher scores in depression and hospital visits as well as days of corticosteroid intake were significant. Furthermore, considerable variance in all subscales of quality of life questionnaires was explained by higher scores in depression, even when controlling for anxiety. For anxiety scores these associations were comparable, except for physical well-being. CONCLUSION Depression is an important issue in asthma, as it is substantially related to quality of life and intake of corticosteroids, and marginally to hospitalization. Routine screening for depression should be considered in hospital and primary care.
