Psychological burden associated with worse clinical outcomes in sarcoidosis.

Introduction: Sarcoidosis is a multisystem granulomatous inflammatory disorder. Sarcoidosis is associated with significant morbidity and rising healthcare utilisation. Patients with sarcoidosis report higher psychological symptoms than the general population. We evaluated the association between depressive and anxiety symptoms and clinical outcomes in patients with pulmonary sarcoidosis requiring treatment. Methods: Adult patients in the Johns Hopkins Sarcoidosis Clinic diagnosed with pulmonary sarcoidosis on treatment were eligible for enrollment. Questionnaires were administered to assess depressive and anxiety symptoms, healthcare utilisation and health-related quality of life (HRQoL). Results: 112 participants were enrolled (57% women, 53% African American, median age: 57 years). 34% of participants screened positive for mild and 20% for moderate-severe depressive symptoms. 25% of participants screened positive for mild and 12% for moderate-severe anxiety symptoms. Participants with moderate-severe psychological symptoms had a higher odds of an emergency department visit in the previous 6 months (8.87 for depressive symptoms and 13.05 for anxiety symptoms) and worse HRQoL compared with participants without psychological symptoms. Participants with moderate-severe depressive symptoms had lower diffusion capacity of the lungs for carbon monoxide % predicted compared with those without depressive symptoms. There was no association between elevated psychological symptoms and the odds of hospitalisation, forced vital capacity % predicted and forced expiratory volume in 1 second % predicted. Conclusion: Psychological symptoms may be associated with worse clinical outcomes in sarcoidosis. Improving the recognition through clinic screening and referral for treatment of depression and anxiety in sarcoidosis may reduce acute healthcare utilisation and improve HRQoL.

Fatigue in sarcoidosis and idiopathic pulmonary fibrosis: differences in character and severity between diseases.

BACKGROUND: Sarcoidosis and idiopathic pulmonary fibrosis (IPF) are two common forms of interstitial lung disease. Fatigue is a recognised feature of sarcoidosis but an association between IPF and fatigue has not been investigated. RATIONALE: To investigate the frequency and severity of fatigue in these groups, and variables affecting fatigue scores. METHODS: A cross-sectional questionnaire study of patients with sarcoidosis and IPF followed-up at a single hospital was undertaken. Questionnaire data included validated measures of fatigue, anxiety, depression, sleepiness and dyspnoea, plus measures of disease severity including spirometry data. RESULTS: Questionnaires were administered to 232 patients (82 healthy volunteers, 73 sarcoidosis patients and 77 IPF patients). Sarcoidosis patients had statistically higher sleepiness scores but no significant difference was seen between overall measures of fatigue, anxiety or depression. Stratification by severity revealed a non-statistically significant tendency towards more severe fatigue scores in sarcoidosis. Regression analysis failed to identify any significant predictor variables measured in the sarcoidosis cohort, though in the IPF group both dyspnoea and sleepiness scores were significant predictors of fatigue (R2=0.74). CONCLUSIONS: Both sarcoidosis and IPF patients suffer with fatigue, although sarcoidosis patients tended towards reporting more severe fatigue scores, suggesting a subgroup with severe fatigue. The fatigue experienced by the two groups appears to be different; sarcoidosis patients report greater frequency of mental fatigue whereas IPF patients appear to suffer exhaustion, potentially related to dyspnoea. Dyspnoea and sleepiness scores modeled the majority of fatigue in the IPF group, whereas no single factor was able to predict fatigue in sarcoidosis.

Predictors of objective cough frequency in pulmonary sarcoidosis.

Cough is a common symptom of pulmonary sarcoidosis. This study aimed to quantify cough frequency, and investigate its relationship with cough reflex sensitivity, pulmonary function and health status.32 patients with pulmonary sarcoidosis were compared with 40 healthy controls. Cough reflex sensitivity to capsaicin, objective 24-h cough counts, cough-specific health status, cough severity and cough triggers were measured. The predictors of cough frequency in sarcoidosis were determined in a multivariate analysis.Objective cough frequency was significantly raised in patients with sarcoidosis compared with healthy controls (p<0.001) and patients with cough had an impaired health status. Patients with pulmonary sarcoidosis had a heightened cough reflex sensitivity compared with healthy controls (p<0.001). Only cough reflex sensitivity was significantly associated with objective cough frequency in multivariate analysis, explaining 42% of the variance (p<0.001). There was no association between cough frequency, lung function, number of organs involved, chest radiograph stage or serum angiotensin-converting enzyme levels.Cough is a common and significant symptom in patients with sarcoidosis. Ambulatory objective cough monitoring provides novel insights into the determinants of cough in sarcoidosis, suggesting that cough reflex sensitivity may be more important than lung function and other measures of disease severity, and this should be investigated further.

Patient confidence and quality of life in idiopathic pulmonary fibrosis and sarcoidosis.

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) and sarcoidosis impact significantly on health-related quality of life (HRQOL). There are few studies on the impact of patient confidence on HRQOL in these conditions. OBJECTIVES: 1. To investigate whether patient confidence is associated with HRQOL, anxiety, depression, dyspnoea or fatigue. 2. To assess if patient confidence is associated with inpatient admissions, access to community healthcare and, for IPF patients, mortality and disease severity. METHODS: Study participants self-completed seven questionnaires: Hospital Anxiety and Depression Scale, EuroQol 5D (EQ5D), King's Brief Interstitial Lung Disease questionnaire, St George's Respiratory Questionnaire, MRC dyspnoea scale, Fatigue Assessment Scale and a non-validated questionnaire assessing patient confidence, symptom duration and access to community healthcare. Lung function and follow-up data were collected from hospital electronic databases. Spearman's rank correlation coefficients were calculated to assess for correlation between patient confidence, questionnaire variables and inpatient admissions. Chi-square tests were performed to assess for association between patient confidence, mortality and disease severity. RESULTS: 75 IPF patients and 69 sarcoidosis patients were recruited to the study. Patient confidence in IPF was significantly negatively correlated with depression and fatigue, and significantly positively correlated with EQ5D scores, but not healthcare outcomes. No associations were found between confidence and any of the variables assessed in sarcoidosis. CONCLUSIONS: Lower levels of confidence in IPF patients are associated with higher levels of depression and fatigue and worse HRQOL. Efforts should be made to improve patient confidence to assess the impact on HRQOL.

Type D or 'distressed' personality in sarcoidosis and idiopathic pulmonary fibrosis.

BACKGROUND: Personality factors have shown to be related to mortality, morbidity, and psychological aspects in chronic disorders. Little is known about the effect of personality on disease severity in sarcoidosis and idiopathic pulmonary fibrosis (IPF). The aim of this study was to assess the prevalence of Type D personality and its relation with relevant clinical characteristics in sarcoidosis and IPF patients. METHODS: The study included 441 sarcoidosis and 49 IPF patients from the outpatient clinic of the ild care team of the MUMC, the Netherlands. They completed the DS14 (Type D questionnaire), the fatigue assessment scale (FAS), the WHO quality of life-BREF (WHOQOL-BREF) and the Centre for Epidemiological Studies-Depression Scale (CES-D). Moreover, relevant clinical data were collected. The control group consisted of 3678 subjects from a general population. RESULTS: Type D personality was found in 25.6% of the sarcoidosis patients compared to 21% in the controls, but only in 18.8% of the IPF patients. No relation with disease severity was found in either of these disorders. Fatigue was a substantial problem in both populations. Depressive symptoms but not Type D personality predicted fatigue and poorer QOL in sarcoidosis and IPF. CONCLUSION: Prevalence of Type D personality is not higher in sarcoidosis and IPF patients than in the general population and does not explain QOL impairment. Depressive symptoms explain QOL impairment and fatigue substantially. Therefore, in the multidisciplinary management of sarcoidosis and IPF psychological screening and psychological counselling concerning adequate coping strategies should be incorporated.

Everyday cognitive failure in sarcoidosis: the prevalence and the effect of anti-TNF-alpha treatment.

BACKGROUND: Cognitive symptoms, such as concentration problems, are frequently recorded by sarcoidosis patients. OBJECTIVES: The aim of this study was to assess the prevalence of perceived everyday cognitive failure in sarcoidosis patients and healthy controls. Furthermore, the effect of treatment on cognitive functioning was examined. METHODS: The study included 343 sarcoidosis patients (44.6% females; age 49.3 +/- 11.0 years). They completed the Cognitive Failure Questionnaire (CFQ) and Fatigue Assessment Scale (FAS) at baseline and the 6-month follow-up to evaluate the effect of treatment on cognitive functioning. The control group consisted of 343 age- and sex-matched healthy controls. RESULTS: The mean CFQ score was significantly higher in sarcoidosis patients (37.3 +/- 16.1) compared with the controls (31.3 +/- 10.1; p < 0.0001).A high CFQ sore (> or =43) was found in 35.0% of the patients and only 14.3% of the controls. No relation with disease severity and duration, or disease location was found. The proportion of patients receiving treatment did not differ among the groups with high and normal CFQ score. At the 6-month follow-up, only patients recently treated with anti-TNF-alpha therapy (n = 42) demonstrated a significant improvement in the CFQ score (Delta -7.07 +/- 7.23) compared with the untreated patients (Delta -0.08 +/- 9.35) and patients treated with prednisone with or without methotrexate (Delta 1.67 +/- 9.22; p < 0.0001). After adjustment for the concomitant decrease in fatigue, the effect of anti-TNF-alpha therapy remained high and significant. CONCLUSIONS: Subjective cognitive failure is a substantial problem in sarcoidosis patients regardless of disease severity. Anti-TNF-alpha therapy had a positive effect on cognition, fatigue and other symptoms of sarcoidosis.

Can sarcoidosis cause autoamputation of a finger phalanx?

Sarcoidosis is a multisystemic granulomatous disease. In the case presented, autoamputation of the distal phalanx of a little finger of the left hand was observed. The possibility of autodigital amputation as a result of sarcoidosis is discussed.

[A role of social and occupational factors in the development of chronic forms of respiratory sarcoidoisis and its relapses].

The social status and the presence of occupational and household hazards were analyzed in 134 patients with torpid chronic and undulating course of sarcoidosis lasting 3 years or more to estimate the significance of the above factors when the course of sarcoidosis was poor. The fact that 162 cases of hazards (metals, building materials, wood, textile, and paper dust, smoking, chemical substances, contact with patients with tuberculosis) occurred in 113 patients and 49 of the 134 patients with chronic forms of the disease were exposed to psychoemotional factors suggests that dust substances and chemical elements of different kinds, frequent stressful situations, and the X-ray signs of fibrosis of sarcoidosis-induced changes due to the absence of timely examinations should be regarded as a risk factors of the torpid chronic course of respiratory sarcoidosis (just at the stage of its primary detection).

Pulmonary and psychosocial findings at enrollment in the ACCESS study.

AIM: To assess lung involvement and the association of demographic and psychosocial factors with respiratory health in 736 persons with sarcoidosis at enrollment in A Case Control Etiologic Study of Sarcoidosis (ACCESS). METHODS: 736 patients with biopsy diagnosis of sarcoidosis within 6 months of enrollment were studied at 10 US centers. Lung involvement was evaluated by chest radiography, spirometry and dyspnea questionnaire. Demographics, number of involved extrathoracic organ systems, comorbidities, and health-related quality of life (HRQL) were assessed. RESULTS: 95% of patients had lung involvement. 8% were Scadding Stage 0, 40% I, 37% II, 10% III, and 5% IV 51% reported dyspnea. Increasing radiographic lung stage was associated with decreasing Forced Vital Capacity (FVC) (p < 0.01). Patients with higher stages had more airways obstruction and dyspnea. 46% of cases and 27% of controls had Center for Epidemiologic Studies Depression Scale (CES-D) scores of 9 or greater, (p < 0.001). Age > or = 40, African-American race, body mass index > or = 30kg/m2, and CES-D scores > 9 were associated with decreased FVC and greater dyspnea. Impaired spirometry and greater dyspnea were associated with poorer quality of life. CONCLUSION: A "global" approach to the sarcoidosis patient, including careful assessment of dyspnea and health related quality of life, as well as of lung function and radiographic changes, and any extrathoracic involvement, is important, not only in management of the individual patient, but should also prove beneficial in assessing outcomes in clinical trials in the future.
