Psychiatric issues in pulmonary disease

Psychiatric disorders and psychological distress in patients undergoing evaluation for lung transplantation: a national cohort study

OBJECTIVE

We sought to investigate type and prevalence of psychiatric disorders and psychological distress in patients being evaluated for lung transplantation.

METHODS

One hundred eighteen patients were assessed [74% with chronic obstructive pulmonary disease (COPD)] with the MINI Neuropsychiatric Interview, the General Health Questionnaire (GHQ), and Hospital Anxiety Depression Scale (HADS). Spirometry and the 6-min walk test (6MWT) assessed lung function with data subject to multivariate regression analyses.

RESULTS

Current and lifetime prevalence for mental disorders were 41.5% and 61.0% respectively, with anxiety (39.8% of patients), mood disorders (11.8%), and subsyndromal disorders (8.7%) identified. 15% of patients reported feelings of panic during the last week, 9% reported hopelessness, and 3% felt that life was not worth living. Statistically significant correlates were derived for HADS-depression with lung function (P=.0012) and 6MWT (P=.030) for the entire group (P=.012), and with lung function (P=.030) for COPD patients (P=.045), for whom higher chronic GHQ-scores correlated with poorer lung function (P=.009). In multivariate regression analysis, history of mental disorder was strongest predictor of current distress.

CONCLUSIONS

Our findings underline the importance of assessing past, current, and sub-syndromal psychiatric disorders in addition to levels of distress in transplant candidates, with prospective studies needed to investigate impact on long-term outcome after transplantation.

"Everything was spiraling out of control": experiences of anxiety in people with chronic obstructive pulmonary disease

OBJECTIVE

This study sought to elicit and describe the first-hand experiences of anxiety in community patients with stable chronic obstructive pulmonary disease (COPD). Anxiety is common among patients with COPD. Clinical anxiety affects up to two thirds of patients, leading to reduced quality of life and physical functioning. There has been little research exploring the experiences of anxiety in patients with COPD, particularly in individuals with stable respiratory symptoms.

METHODS

We interviewed 14 community patients with stable COPD and self-reported symptoms of anxiety. Data were analyzed using thematic network analysis to develop basic, organizing, and global themes.

RESULTS

Patients reported intense thoughts of fear, hopelessness, and confusion that were associated with the anxiety and panic attacks. Self-management was important, particularly self-talk coping strategies.

CONCLUSIONS

Unmanaged anxiety seems to be particularly distressing for patients with COPD. Self-management strategies can be highly effective in preventing and managing anxiety.

Psychosocial aspects of pulmonary hypertension: a review

Pulmonary arterial hypertension (PAH) is characterized by progressive and sustained elevation of pulmonary-artery pressure, which ultimately leads to right-ventricular failure and death. The diagnosis carries with it an uncertain and historically very bleak prognosis. Although new oral and chronic parenteral (intravenous and subcutaneous) treatments have had a significant positive medical impact on the physical functioning of individuals with PAH, patients often struggle with new short- and long-term psychosocial challenges. The purpose of the current article is to 1) provide a brief review of PAH and its treatment; 2) summarize the limited literature examining the psychosocial adjustment of those with a PAH diagnosis; and 3) provide pertinent information extrapolated from the larger literature on chronic illness that might inform us on the psychosocial challenges faced by the patient diagnosed with PAH.

Psychological disorders and distress after adult cardiothoracic transplantation

This review summarizes and integrates evidence concerning mental health outcomes following heart, lung, and heart-lung transplantation. Drawing on English-language case reports and empirical studies published between January 1980 and December 2004, the goals of the review were to (a) describe the prevalence and clinical characteristics of psychological disorders, as well as the level and pattern of clinically significant distress in the years posttransplant; (b) review the major risk factors for poor posttransplant psychological outcomes; (c) consider evidence suggesting that posttransplant psychological outcomes predict physical morbidity and mortality after transplant; (d) summarize findings from intervention studies designed to improve posttransplant psychological outcomes; and (e) provide patient care recommendations for the practicing clinician and recommendations for continued clinical research. Several major conclusions can be drawn from this literature. First, depressive and anxiety-related disorders and associated distress are common posttransplant. While new onsets of disorder may decline after the first year posttransplant, the development of new medical complications in the late years posttransplant may provoke renewed distress and recurrences of disorder. Second, risk factors for posttransplant psychological disorders and elevated distress include both standard risk factors observed in other populations (eg, younger age, lifetime history of psychiatric disorder) and transplant-specific factors related to physical functional impairments, social supports, and strategies for coping with health problems. Third, while little evidence has been published to date, there is some indication that posttransplant psychological outcomes can predict subsequent physical health outcomes. Fourth, extremely few intervention studies in cardiothoracic transplant recipients have been performed. The few reports indicate that multicomponent psychosocial strategies focused on risk factor reduction and enhancement of personal coping resources may lead to reductions in psychological distress. An important caveat in considering all of the evidence reviewed is that most studies focus on heart rather than lung or heart-lung recipients. Recommendations for practicing clinicians focus on assessment and treatment options, based on the evidence to date. Research recommendations focus on the need for intervention effectiveness studies.

Asthma and depression: a pragmatic review of the literature and recommendations for future research

BACKGROUND

Although the association between asthma and psychosocial factors has long been recognised, it is only in the last decade that the impact of coexisting asthma and depression has become the focus of considerable research interest. However, the findings so far have been confusing and often contradictory. This paper sets out a methodical review and appraisal of the literature to date, including suggestions for future research.

METHOD

PubMed and PsycINFO databases were used to search for English-language articles relating to asthma and depression research. The resulting articles were then reviewed and summarised, creating a report that was used to develop research recommendations.

RESULTS

The main findings from this review included: (a) results are mixed as to whether persons with asthma are more likely to be depressed than those without asthma; (b) asthma and depression may have an 'additive' adverse effect on the normal asthma-related quality of life reductions; (c) subjective measures of asthma severity may be more strongly related to depression than objective measures; (d) specific asthma symptoms appear to be linked to depression; (e) sadness and depression can produce respiratory effects consistent with asthma exacerbations; (f) depression appears to be negatively related to asthma treatment compliance; (g) corticosteroid use in asthma treatment has been associated with depression, though it is unclear how common this problem is in real life; (h) interventions that address the physical, psychological, and social consequences of asthma are likely to lead to the most successful treatment outcomes; (i) treating the depression of individuals with asthma is likely to minimise the negative effects of the coexistence; and (j) a number of common methodological problems were observed in the literature.

RECOMMENDATIONS

There is a large amount of research yet to be undertaken to clarify issues around asthma and depression, with the overdue next step being to design integrated treatment approaches, and carry out large-scale prospective studies to determine the impact of using such approaches to treat individuals with depression and asthma. Such studies will be the only way in which some fundamental questions about the development and coexistence of these two conditions will be answered.

Major depression and the use of electroconvulsive therapy (ECT) in lung transplant recipients

The purpose of this study is to describe the potential risks and benefits of electroconvulsive therapy (ECT) for treatment of depression in lung transplant recipients. The authors performed a record review of depressed patients who underwent lung transplantation at Johns Hopkins Hospital and evaluated their treatment, including ECT. In 9 years, 131 lung transplants were performed, and four patients had been diagnosed with major depression. Of those, two were candidates for ECT, and one received it. This patient's depression did abate with ECT. ECT, an effective treatment for depression, remains a treatment method of choice for depression in the posttransplant population.
