Depression in sarcoidosis

Obstructive Sleep Apnea and Sarcoidosis Interactions

Obstructive sleep apnea (OSA) is very prevalent in sarcoidosis patients. Sarcoidosis of the upper respiratory tract may affect upper airway patency and increase the risk of OSA. Weight gain due to steroid use, upper airway myopathy due to steroids and sarcoidosis itself, and interstitial lung disease with decreased upper airway patency are other reasons for the higher OSA prevalence seen in sarcoidosis. Several clinical manifestations such as fatigue, hypersomnolence, cognitive deficits, and pulmonary hypertension are common to both OSA and sarcoidosis. Therefore, early screening and treatment for OSA can improve symptoms and overall patient quality of life.

Characteristics and clinical outcomes of patients with sarcoidosis admitted for ST-elevation myocardial infarction in the United States: a propensity matched analysis from the National Inpatient Sample

Introduction

Sarcoidosis is a systemic inflammatory disorder characterised by non-caseating granulomas. Cardiac sarcoidosis (CS) normally causes conduction abnormalities, ventricular arrhythmias, and heart failure. Little is known about the characteristics and impact of sarcoidosis in patients admitted with ST-elevation myocardial infarction (STEMI). This study aims to fill this void.

Material and methods

Utilising the National Inpatient Sample (NIS) database (2016-2020), individuals with STEMI were identified and categorised based on sarcoidosis presence whilst adjusting for confounders via logistic regression models.

Results

Among 851,290 STEMI patients, 1215 had sarcoidosis. Before propensity matching, sarcoidosis patients were notably different in demographics and comorbidities compared to non-sarcoidosis patients. After propensity score matching (PSM), sarcoidosis patients were found to have a higher incidence of supraventricular tachycardia (SVT) (2.5% vs. 1.3%, p = 0.024) and acute kidney injury (AKI) (23.3% vs. 20.8%, aOR = 1.269, 95% CI: 1.02-1.58, p = 0.033) but a lower incidence of undergoing coronary artery bypass graft (CABG) (5.5% vs. 8.5%, aOR = 0.663; 95% CI: 0.472-0.931, p = 0.018), while no significant disparities were noted in PCI, cardiogenic shock, mortality, or mean length of stay (LOS).

Conclusions

Using propensity-matched large real-world data of STEMI patients, sarcoidosis was associated with fewer cases of CABG and a greater incidence of AKI and SVT compared to non-sarcoidosis patients.

Health-Related Quality of Life Assessment in Sarcoidosis

Health-related quality of life (HRQoL) is of major concern to patients with sarcoidosis. HRQoL impairment is the most common reason to treat the disease. Advances in patient-reported outcome (PRO) methodology offer the promise to use these instruments to follow quality of life in individual patients with sarcoidosis over time. Several HRQoL issues will be highlighted including their clinical importance, common causes in patients with sarcoidosis, the construction and use of PROs in clinical sarcoidosis trials, methods to adapt PROs to monitor HRQoL in individual patients with sarcoidosis, and the approach to improving HRQoL in this disease.

Influence of pulmonary rehabilitation on symptoms of anxiety and depression in interstitial lung disease: A systematic review of randomized controlled trials

BACKGROUND

Interstitial lung diseases (ILDs) cause fibrosis of lung parenchyma, leading to impaired quality of life, dyspnea, and functional decline. Individuals with ILD experience a high prevalence of anxiety and depression. Recent research has demonstrated pulmonary rehabilitation (PR) alleviates symptoms of anxiety and depression in those with COPD.

RESEARCH QUESTION

What is the influence of PR on symptoms of anxiety and depression in individuals with ILD?

STUDY DESIGN

We conducted a PRISMA-2020-compliant systematic review of randomized controlled trials (RCTs) investigating PR's effect on anxiety and depression in patients with ILD. We searched MEDLINE, EMBASE, Cochrane, and PsycINFO from inception until April 3, 2023. A narrative synthesis was conducted where a quantitative approach was not feasible.

RESULTS

Five RCTs (n = 281) were included. Idiopathic pulmonary fibrosis (IPF) was the most common type of ILD (k = 3). One study reported clinically-significant improvements in symptoms of anxiety among patients with IPF, and two studies for symptoms of depression among patients with sarcoidosis. Dropout rates were similar between intervention and control groups. All studies were at a high risk of bias.

INTERPRETATION

Pulmonary rehabilitation is not detrimental to anxiety or depression for patients with ILD, and may improve symptoms of anxiety in IPF and depression in sarcoidosis. However, no conclusion can be drawn from available evidence, which is limited by heterogeneous populations/interventions, sample sizes and unexpectedly low prevalences of clinically-significant anxiety or depression. Further adequately powered RCTs that focus on anxiety and depressive symptoms as primary outcomes are needed.

Quality of life in sarcoidosis

Having sarcoidosis often has a major impact on quality of life of patients and their families. Improving quality of life is prioritized as most important treatment aim by many patients with sarcoidosis, but current evidence and treatment options are limited. In this narrative review, we describe the impact of sarcoidosis on various aspects of daily life, evaluate determinants of health-related quality of life (HRQoL), and provide an overview of the different patient-reported outcome measures to assess HRQoL in sarcoidosis. Moreover, we review the current evidence for pharmacological and non-pharmacological interventions to improve quality of life for people with sarcoidosis.

Exertional Dyspnea Incidentally Diagnosed as Sarcoidosis: A Teaching Hospital Experience

Background

Sarcoidosis is a complex disease with nonspecific etiology and clinical presentation. Its diagnosis is often delayed due to the absence of a single specific investigation modality. A multidisciplinary approach is necessary for its diagnosis. Report. A 49-year-old male presented with recurrent dyspnea on exertion, easy fatigue, and chest pain after several visits to different health facilities over 5 months. A diagnosis of pulmonary sarcoidosis was made after a series of laboratory and imaging investigations were done revealing bilateral reticonodular opacifications, noncaseating granulomata, elevated serum ACE and calcium levels consistent with sarcoidosis.

Conclusion

Sarcoidosis, although a rare presentation in our setting, may easily be overlooked or misdiagnosed if a holistic or multidisciplinary approach is not employed in its diagnosis. Nonspecificity of symptoms contributes to the delayed diagnosis.

The management of sarcoidosis in the 2020's by the primary care physician

Sarcoidosis is an idiopathic granulomatous disease that occurs worldwide and may affect any organ. Because the presenting symptoms of sarcoidosis are not specific for the disease, the primary care physician is usually the first provider to assess these patients. In addition, patients who have previously been diagnosed with sarcoidosis are usually followed longitudinally by primary care physicians. Therefore, these physicians are often the first to address sarcoidosis patient symptoms related to exacerbations of the disease, as well as first observe complications of sarcoidosis medications. This article outlines the approach to the evaluation, treatment and monitoring of sarcoidosis patients by the primary care physician.

An Atypical Case of Extrapulmonary Sarcoidosis

Sarcoidosis is an idiopathic, inflammatory condition that affects nearly all organs in the body. Lungs are the most frequent and among the earliest sites for detecting it. The most common extrapulmonary manifestations involve the ophthalmic, cardiac, nervous, reticuloendothelial, cutaneous, hepatosplenic, and renal systems. These extrapulmonary manifestations of sarcoid may be misdiagnosed in the absence of the classical pulmonary features, given the high overlap of features with other chronic immunologic diseases. The diagnostic workup to differentiate sarcoid from other similar conditions is extensive, amongst which histology remains a gold standard tool for the diagnosis. Our patient presented with a chronic history of multiple vague complaints including nausea, vomiting, progressive malaise, vision changes, and weight loss. After extensive workup, a diagnosis of sarcoidosis along with multiple rare extrapulmonary involvements was made. The authors highlight essential implications including primary practice goals to avoid misdiagnosis or missed sarcoid diagnoses thus helping improve clinical outcomes in similar populations.

The clinical correlations of fatigue in patients with sarcoidosis

Introduction: Fatigue is considered a frequent and characteristic feature of sarcoidosis. This study was designed to determine the prevalence of fatigue in patients with sarcoidosis and to determine its potential clinical correlations in relation to symptom severity. Methods: A total of 56 sarcoidosis patients were included. Data on patient demographics, anthropometrics, disease characteristics, pulmonary function tests, 6-min walking distance (6MWD), blood biochemistry and hemogram findings were retrieved from hospital records. Psychometric instruments involved fatigue assessment scale (FAS), Beck Depression Inventory (BDI) and Short Form-36 (SF-36) for health-related QOL (HRQOL). Results: Mean±SD patient age was 50.9±11.9 years. Of 56 patients, 44 were females and 12 were males. When compared to FAS score

A prospective, one-year follow-up study of patients newly diagnosed with neurosarcoidosis

METHODS

Twenty patients with newly diagnosed neurosarcoidosis were examined for multiple outcomes in an observational cohort study with 12-month follow-up.

RESULTS

The patients' contrast-enhancing lesions on MRI scans reduced during treatment (p < 0.0001). The mean modified Rankin Score improved from 3.0 to 1.8 (p < 0.0001), and 75% of patients experienced clinically important improvement. Patients improved on the Symbol Digit Modalities Test (p < 0.0001) and on SF-36 Physical (p = 0.003) and Mental Component Summary scores (p = 0.03). Proportions of patients with substantial fatigue (75%) and high depression score (35%) were unchanged.

CONCLUSIONS

12-month immunosuppression improved several outcomes, and 75% of patients experienced clinically important improvement.

Management of Advanced Pulmonary Sarcoidosis

The term "advanced sarcoidosis" is used for forms of sarcoidosis with a significant risk of loss of organ function or death. Advanced sarcoidosis often involves the lung and is described as "Advanced Pulmonary Sarcoidosis" (APS) which includes advanced pulmonary fibrosis, associated complications such as bronchiectasis and infections, and pulmonary hypertension. While APS affects a small proportion of patients with sarcoidosis, it is the leading cause of poor outcomes including death. Herein we review the major patterns of APS with a focus on the current management as well as potential approaches for improved outcomes for this most serious sarcoidosis phenotype.

Sarcoidosis-Related Cardiomyopathy: Current Knowledge, Challenges, and Future Perspectives State-of-the-Art Review

The prevalence of sarcoidosis-related cardiomyopathy is increasing. Sarcoidosis impacts cardiac function through granulomatous infiltration of the heart, resulting in conduction disease, arrhythmia, and/or heart failure. The diagnosis of cardiac sarcoidosis (CS) can be challenging and requires clinician awareness as well as differentiation from overlapping diagnostic phenotypes, such as other forms of myocarditis and arrhythmogenic cardiomyopathy. Clinical manifestations, extracardiac involvement, histopathology, and advanced cardiac imaging can all lend support to a diagnosis of CS. The mainstay of therapy for CS is immunosuppression; however, no prospective clinical trials exist to guide management. Patients may progress to developing advanced heart failure or ventricular arrhythmia, for which ventricular assist device therapies or heart transplantation may be considered. The existing knowledge gaps in CS call for an interdisciplinary approach to both patient care and future investigation to improve mechanistic understanding and therapeutic strategies.

Socioeconomic determinants and disparities in sarcoidosis

PURPOSE OF REVIEW

The aim of this article is to describe the known health disparities that exist among patients with sarcoidosis by socioeconomic status, race, and gender, review potential contributors to health disparities in sarcoidosis, investigate the intersectionality among socioeconomic status, race, and gender in sarcoidosis, and outline a research agenda to address these disparities.

RECENT FINDINGS

Recent studies have reported the significant financial strain a diagnosis of sarcoidosis has on individuals and the disproportionate affect the strain has on low socioeconomic status individuals, Blacks, and females. Worse dyspnea, lower health-related quality of life, and higher rates of mortality and hospitalization are more common among those who are Black, female, or of low socioeconomic status.

SUMMARY

Health disparities in sarcoidosis by socioeconomic status, race, and gender have been described for decades. In this review, we describe potential contributors to health disparities including stress and propose interventions to address disparities including creating educational programs accessible for low-income patients and caregivers, targeting medication adherence and trust in physicians and the medical system, and ensuring access to high-quality care for all patients. As clinicians and researchers, we owe it to our patients to not only describe the health disparities that exist but also stimulate to achieve improvement in sarcoidosis.

Health-Related Quality of Life (HRQoL) in Sarcoidosis: Diagnosis, Management, and Health Outcomes

Health-related quality of life (HRQoL), though rarely considered as a primary endpoint in clinical trials, may be the single outcome reflective of patient priorities when living with a health condition. HRQoL is a multi-dimensional concept that reflects the degree to which a health condition interferes with participation in and fulfillment of important life areas. HRQoL is intended to capture the composite degree of physical, physiologic, psychological, and social impairment resulting from symptom burden, patient-perceived disease severity, and treatment side effects. Diminished HRQoL expectedly correlates to worsening disability and death; but interventions addressing HRQoL are linked to increased survival. Sarcoidosis, being a multi-organ system disease, is associated with a diffuse array of manifestations resulting in multiple symptoms, complications, and medication-related side effects that are linked to reduced HRQoL. Diminished HRQoL in sarcoidosis is related to decreased physical function, pain, significant loss of income, absence from work, and strain on personal relationships. Symptom distress can result clearly from a sarcoidosis manifestation (e.g., ocular pain, breathlessness, cough) but may also be non-specific, such as pain or fatigue. More complex, a single non-specific symptom, e.g., fatigue may be directly sarcoidosis-derived (e.g., inflammatory state, neurologic, hormonal, cardiopulmonary), medication-related (e.g., anemia, sleeplessness, weight gain, sub-clinical infection), or an indirect complication (e.g., sleep apnea, physical deconditioning, depression). Identifying and distinguishing underlying causes of impaired HRQoL provides opportunity for treatment strategies that can greatly impact a patient's function, well-being, and disease outcomes. Herein, we present a reference manual that describes the current state of knowledge in sarcoidosis-related HRQoL and distinguish between diverse causes of symptom distress and other influences on sarcoidosis-related HRQoL. We provide tools to assess, investigate, and diagnose compromised HRQoL and its influencers. Strategies to address modifiable HRQoL factors through palliation of symptoms and methods to improve the sarcoidosis health profile are outlined; as well as a proposed research agenda in sarcoidosis-related HRQoL.

Screening Sarcoidosis Patients for Occult Disease

As sarcoidosis may involve any organ, sarcoidosis patients should be evaluated for occult disease. Screening for some organ involvement may not be warranted if it is unlikely to cause symptoms, organ dysfunction, or affect clinical outcome. Even organ involvement that affects clinical outcome does not necessarily require screening if early detection fails to change the patient's quality of life or prognosis. On the other hand, early detection of some forms of sarcoidosis may improve outcomes and survival. This manuscript describes the approach to screening sarcoidosis patients for previously undetected disease. Screening for sarcoidosis should commence with a meticulous medical history and physical examination. Many sarcoidosis patients present with physical signs or symptoms of sarcoidosis that have not been recognized as manifestations of the disease. Detection of sarcoidosis in these instances depends on the clinician's familiarity with the varied clinical presentations of sarcoidosis. In addition, sarcoidosis patients may present with symptoms or signs that are not related to specific organ involvement that have been described as parasarcoidosis syndromes. It is conjectured that parasarcoidosis syndromes result from systemic release of inflammatory mediators from the sarcoidosis granuloma. Certain forms of sarcoidosis may cause permanent and serious problems that can be prevented if they are detected early in the course of their disease. These include (1) ocular involvement that may lead to permanent vision impairment; (2) vitamin D dysregulation that may lead to hypercalcemia, nephrolithiasis, and permanent kidney injury; and (3) cardiac sarcoidosis that may lead to a cardiomyopathy, ventricular arrhythmias, heart block, and sudden death. Screening for these forms of organ involvement requires detailed screening approaches.

Corticosteroid refractory sarcoidosis

A sarcoidosis patient may be refractory to corticosteroid therapy. This may be because corticosteroids are ineffective in relieving the sarcoidosis patient's symptoms/dysfunction or because the clinician has determined that the risks of corticosteroids outweigh their benefits. Interestingly, when corticosteroids truly fail to improve a sarcoidosis patient's condition, it is very rarely because of failure of the drug as an anti-granulomatous agent; rather, it is usually because the patient's symptoms were unrelated to active sarcoid granulomas. In this manuscript, we review the causes of corticosteroid refractory sarcoidosis. The clinician should consider these causes when confronted with a sarcoidosis patient who is either not responding to corticosteroids, developing corticosteroid side-effects, or is at significant risk of developing such side-effects. We believe that determining the cause of corticosteroid refractory sarcoidosis may aid the clinicians in optimizing the care of sarcoidosis patients and clinical researchers in appropriately stratifying patients for clinical trials.

Sarcoidosis and increased risk of comorbidities and mortality in sweden

Introduction:

Sarcoidosis is a systemic inflammatory disorder, with an unclear etiology, involving granuloma formation that in most cases affects the lungs and intrathoracic lymph nodes. Sarcoidosis occurs in an acute or chronic form, each with different clinical presentation and prognosis.

Methods:

Case-control study of comorbidity and mortality in people diagnosed with sarcoidosis (ICD10 code D86) from 2007 through 2016 in Sweden. Controls were matched to cases (2:1) based on age, sex and county at the time of diagnosis. Data was collected from the Swedish National Patient Register and The Cause of Death Register. All men and women aged 20-65 years old who were diagnosed with sarcoidosis (D86, ICD10) during the years of study were included, resulting 7828 cases and 15656 controls.

Results:

Patients with sarcoidosis had increased mortality compared to matched controls (hazard ratio 1.88; 95% CI 1.56 – 2.26) and the Swedish general population (standardized mortality ratios1.75; 95% CI 1.52 – 2.00). The sarcoid cases, compared to controls, also had a significantly greater number of inpatient visits within several different chapters of ICD10 e.g. cardiomyopathy, heart failure, pulmonary embolism and malignant neoplasm.

Conclusion:

Individuals with sarcoidosis are at higher risk of comorbidities and mortality than matched controls as well as the general population of Sweden. These findings are important knowledge for healthcare professionals who meet sarcoid patients, to encourage identification and treatment of comorbidities to reduce the risk of impaired quality of life and, eventually, premature death. (Sarcoidosis Vasc Diffuse Lung Dis 2020; 37 (2): 104-135)

Health-Related Quality of Life in Sarcoidosis

Health-related quality of life (HRQoL) describes an individual's perception of the impact of health, disease, and treatment on their quality of life (QoL). It is a reflection of how the manifestation of an illness and its treatment is personally experienced. Assessing HRQoL is particularly important in sarcoidosis because the attributable disease mortality is relatively low, and one of the major reasons for initiating treatment is to improve quality of life. HRQoL has been assessed in sarcoidosis using various generic and sarcoid-specific patient-reported outcome measures (PROMs). It is important that both the direct and indirect effects of the disease, as well as potential toxicities of therapy, are captured in the various PROMs used to assess HRQoL in sarcoidosis. This article provides a general overview of HRQoL in patients with sarcoidosis. It describes the various PROMs used to assess HRQoL in sarcoidosis and addresses the various factors that influence HRQoL in sarcoidosis. Specific attention is paid to fatigue, small fiber neuropathy, corticosteroid therapy, and other disease-specific factors that affect HRQoL in sarcoidosis. It also provides an insight into interventions that have been associated with improved HRQoL in sarcoidosis and offers suggestions for future research in this important area.

Comprehensive Care for Patients with Sarcoidosis

Sarcoidosis is a multisystem granulomatous disease, associated with significant morbidity and impaired quality of life. Treatment is aimed at recovering organ function, reducing symptom burden and improving quality of life. Because of the heterogeneity and variable disease course, a comprehensive, multidisciplinary approach to care is needed. Comprehensive care includes not only pharmacological interventions, but also supportive measures aimed at relieving symptoms and improving quality of life. The purpose of this review is to summarize the most recent knowledge regarding different aspects of care and propose a structured approach to sarcoidosis management.

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.

Nonorgan manifestations of sarcoidosis

PURPOSE OF REVIEW

The current review discusses the diagnosis and management of nonorgan-related symptoms that commonly arise in the setting of systemic sarcoidosis. Fatigue, small fiber neuropathy (SFN) and neuropsychological symptoms are highlighted.

RECENT FINDINGS

The debilitating effects of chronic nonorgan-based symptoms in sarcoidosis have led to recent studies focusing on incidence rates, contributing factors and potential therapeutic strategies. In a web-based survey of over 1000 sarcoidosis patients, the most common symptom was fatigue, which was reported by over 90% of participants, whereas memory loss and concentration problems were reported in 50%. SFN was also common, and may be diagnosed with tools such as skin biopsy measurement of intraepidermal nerve fibers and corneal confocal microscopy. In a recent cohort study of SFN patients, serologic evaluation demonstrated other contributing causes such as diabetes and vitamin B12 deficiency, which warrant-specific treatment. Finally, physical inactivity in patients with sarcoidosis correlated with lower quality-of-life (QOL) scores and possibly fatigue. Multidisciplinary programs that include physical therapy, patient education and psychological support were found to improve fatigue and mood disorders.

SUMMARY

Recognition of nonorgan-related symptoms and their impact on patient QOL is essential to optimal treatment of the sarcoidosis patient.

Measurement of cerebrospinal fluid ACE level in aseptic meningitis: diagnostic?

Neurosarcoidosis (NS) is a rare disease, affecting only 3%-10% of patients with sarcoidosis. The clinical presentation can be protean and often represents a diagnostic challenge. Cerebrospinal fluid (CSF) ACE level has poor sensitivity, but high specificity for establishing a diagnosis of NS. We present a case of NS in a middle-aged African American woman who presented with dysphagia and dysphonia. An extensive radiological workup was negative for structural brain disease. CSF studies demonstrated lymphocyte predominant pleocytosis with an elevated ACE level. A diagnosis of possible neurosarcoidosis was made. She responded to systemic steroid therapy with complete resolution of her symptoms over the next five months. In the appropriate clinical setting, an elevated CSF ACE level could be of paramount importance for making a diagnosis of NS.

Quality of Life of Couples Living with Sarcoidosis

BACKGROUND

Consequences of sarcoidosis are wide ranging, and the symptom burden has a great impact on patients' quality of life (QoL). However, the QoL of couples living with sarcoidosis has not yet been studied.

OBJECTIVES

Our aim was to assess the QoL of couples living with sarcoidosis and to evaluate whether living with a partner with sarcoidosis influences the partner's QoL. Furthermore, we aimed to assess whether nonspecific symptoms (fatigue, cognitive failure, small fiber neuropathy (SFN)-related symptoms, depressive symptoms, and state/trait anxiety) predict QoL of partners as well as sarcoidosis patients.

METHOD

Sarcoidosis outpatients, recruited at Maastricht University Medical Centre (n = 443), and their partners (n = 208) completed several questionnaires, including the World Health Organization QoL - BREF, Fatigue Assessment Scale, SFN screening list, and cognitive failure questionnaire.

RESULTS

QoL of the partners as well as the sarcoidosis patients was reduced compared with healthy controls, especially regarding the physical health domain. All nonspecific symptoms studied, as well as perceived social support, predicted one or more QoL domains in the sarcoidosis patients, but these factors did not predict the QoL of their partners.

CONCLUSIONS

The QoL of partners of sarcoidosis patients was reduced, although to a lesser extent than that of the patients. Although the nonspecific symptoms and perceived social support were related to the patients' QoL, this was not the case for the partners. In the management of sarcoidosis, it is important to focus not only on the patients but also on their partners.

Sarcoidosis

Sarcoidosis is an inflammatory disorder of unknown cause that is characterized by granuloma formation in affected organs, most often in the lungs. Patients frequently suffer from cough, shortness of breath, chest pain and pronounced fatigue and are at risk of developing lung fibrosis or irreversible damage to other organs. The disease develops in genetically predisposed individuals with exposure to an as-yet unknown antigen. Genetic factors affect not only the risk of developing sarcoidosis but also the disease course, which is highly variable and difficult to predict. The typical T cell accumulation, local T cell immune response and granuloma formation in the lungs indicate that the inflammatory response in sarcoidosis is induced by specific antigens, possibly including self-antigens, which is consistent with an autoimmune involvement. Diagnosis can be challenging for clinicians because of the potential for almost any organ to be affected. As the aetiology of sarcoidosis is unknown, no specific treatment and no pathognomic markers exist. Thus, improved biomarkers to determine disease activity and to identify patients at risk of developing fibrosis are needed. Corticosteroids still constitute the first-line treatment, but new treatment strategies, including those targeting quality-of-life issues, are being evaluated and should yield appropriate, personalized and more effective treatments.

Needs, Perceptions and Education in Sarcoidosis: A Live Interactive Survey of Patients and Partners

Objectives

Sarcoidosis is a chronic, multisystem disease with often a major impact on quality of life. Information on unmet needs of patients and their partners is lacking. We assessed needs and perceptions of sarcoidosis patients and their partners.

Methods

During patient information meetings in 2015 and 2017 in the Erasmus University Medical Center, we interviewed patients and partners using interactive voting boxes. Patients responded anonymously to 17 questions. Answers were projected directly on the screen in the room.

Results

210 patients and 132 partners participated. Sarcoidosis has a subjective significant impact on lives of both patients and partners. The vast majority of patients and partners feel regularly misunderstood because of the general unawareness of sarcoidosis. Many patients and partners experience anxiety. Three-quarters of patients would like to see more attention and support for their psychological problems. Additionally, more supportive care for partners of sarcoidosis patients is warranted. Interactive interviewing was considered educational (91%) and pleasant (84%).

Discussion

This study improves awareness of needs and perceptions of patients with sarcoidosis and their partners. Sarcoidosis leads to anxiety and psychological distress and impairs well-being of patients and their partners. Attention for psychological support, better disease education, and more supportive care for partners is warranted.

Relationship of emotional distress and physical concerns with fatigue severity in sarcoidosis

Background: Fatigue is one of the most common and disabling symptoms of sarcoidosis. The cause of fatigue remains unclear and is usually multifactorial. The majority of previous studies evaluated clinical parameters with only few of them including assessment of psychological factors as contributing to the severity of the symptoms. Objective: The aim of this study was to evaluate the relationship of emotional distress, physical concerns, and dyspnea in explaining fatigue in patients with sarcoidosis. Methods: Fifty-seven patients with sarcoidosis were enrolled to the study and filled out measures of fatigue (FAS), dyspnea (MRC), anxiety sensitivity (ASI-3), and anxiety and depression (HADS). Results: Linear regression revealed that distress and physical concerns subscale of ASI are significant predictors of fatigue explaining jointly 53.5% of fatigue variance. Conclusions: The results of the study emphasize the importance of including emotional distress and physical concerns into the diagnostic procedures and management of fatigue in sarcoidosis. (Sarcoidosis Vasc Diffuse Lung Dis 2018; 35: 160-164).

Disease Burden and Variability in Sarcoidosis

Sarcoidosis is a systemic inflammatory disease with substantial morbidity and increasing mortality. As part of the National Heart, Lung, and Blood Institute's workshop to better understand this disease and improve the outcomes of patients with sarcoidosis, we reviewed the available data on health care burden and outcomes of this disease in the United States. Disparities in outcomes exist by race, ethnicity, sex, and socioeconomic groups, with African Americans having disproportionately more severe disease. Mortality rates are highest in African Americans, but may be increasing in white individuals. The health care burden of sarcoidosis is defined not only by its somatic manifestations, but is also greatly impacted by psychosocial, economic, and comorbid conditions associated with this disease. Fatigue, depression, cognitive dysfunction, treatment side effects, and pain syndromes are highly prevalent in this population and contribute to poor outcomes. The direct and indirect economic costs to patients and society are likely also substantial, although not well defined. We recommend leveraging existing and future technology and infrastructure to more accurately define and monitor the overall total sarcoidosis-attributable health care burden and patient outcomes in the United States.

Neurosarcoidosis

Neurosarcoidosis occurs in 3% to 10% of patients with sarcoidosis. Cranial neuropathy and meningeal involvement are the most common manifestations, but any part of the nervous system can be affected. Definite diagnosis requires the presence of noncaseating granuloma in the nervous system, although histopathologic confirmation is often not obtainable. Moderate to high dose of glucocorticoids is the main therapy for neurosarcoidosis. Relapse often occurs after the dose of glucocorticoids is tapered down, often necessitating the use of steroid-sparing immunosuppressive agents.

Patient reported outcome measures (PROMs) in sarcoidosis

Patients with sarcoidosis present with a variety of symptoms which may impair many aspects of physical and mental well-being. Traditionally, clinicians have been concerned with physical health aspects of sarcoidosis, assessing disease activity and severity with radiological imaging, pulmonary function and blood tests. However, the most reported symptom of sarcoidosis patients, fatigue, has been shown not to correlate with the most commonly used parameters for monitoring disease activity. Studies have shown poor agreement between physicians and patients in assessing sarcoidosis symptoms. This underlines the importance of patient reported outcomes (PROs) in addition to traditional outcomes in order to provide a complete evaluation of the effects of interventions in clinical trials and everyday clinical assessment of sarcoidosis. We have undertaken a systematic review to identify and provide an overview of PRO concepts used in sarcoidosis assessment the past 20 years and to evaluate the tools used for measuring these concepts, called patient reported outcome measures (PROMs). Various PROMs have been used. By categorizing these PROMs according to outcome we identified the key PRO concepts for sarcoidosis to be Health Status and Quality of Life, Dyspnea, Fatigue, Depression, Anxiety and Stress and Miscellaneous. There is no perfect sarcoidosis-specific PROM to cover all concepts and future intervention studies should therefore contain multiple complementary questionnaires. Based on our findings we recommend the Fatigue Assessment Scale (FAS) for assessing fatigue. Dyspnea scores should be chosen based on their purpose; more research is needed to examine their validity in sarcoidosis. The Modified Medical Research Council Dyspnea Scale (MRC) can be used to screen for dyspnea and the Baseline Dyspnea Index (BDI) to detect changes in dyspnea. We recommend The World Health Organization Quality of Life assessment instrument (WHOQOL-100) for assessing quality of life, although a shorter questionnaire would be preferable. For assessing health status we recommend the Sarcoidosis Assessment Tool (SAT), and have great expectations for this new and promising assessment tool. Supplementary to the WASOG meeting of 2011's recommendation on assessing QoL, we recommend incorporating fatigue, dyspnea and HS assessment in clinical trials and everyday clinical assessment of sarcoidosis. (Sarcoidosis Vasc Diffuse Lung Dis 2017; 34: 2-17).

Administering the Sarcoidosis Health Questionnaire to sarcoidosis patients in Serbia

Objective:

The aim of this study was to use a Serbian-language version of the disease-specific, self-report Sarcoidosis Health Questionnaire (SHQ), which was designed and originally validated in the United States, to assess health status in sarcoidosis patients in Serbia, as well as validating the instrument for use in the country.

Methods:

This was a cross-sectional study of 346 patients with biopsy-confirmed sarcoidosis. To evaluate the health status of the patients, we used the SHQ, which was translated into Serbian for the purposes of this study. We compared SHQ scores by patient gender and age, as well as by disease duration and treatment. Lower SHQ scores indicate poorer health status.

Results:

The SHQ scores demonstrated differences in health status among subgroups of the sarcoidosis patients evaluated. Health status was found to be significantly poorer among female patients and older patients, as well as among those with chronic sarcoidosis or extrapulmonary manifestations of the disease. Monotherapy with methotrexate was found to be associated with better health status than was monotherapy with prednisone or combination therapy with prednisone and methotrexate.

Conclusions:

The SHQ is a reliable, disease-specific, self-report instrument. Although originally designed for use in the United States, the SHQ could be a useful tool for the assessment of health status in various non-English-speaking populations of sarcoidosis patients.

Treatment of Sarcoidosis

Treatment of sarcoidosis is not required in all patients with the diagnosis. The decision to treat and the strategy for how to treat usually require input and shared decision making by the patient. Some common consequences of sarcoidosis are not caused by granulomatous inflammation, but may be the dominant disease manifestation and should be actively considered when formulating a treatment plan. The medication regimen should be tailored to each patient. Steroid-sparing medications should be prescribed early as part of a long-term strategy.

The Clinical Features of Sarcoidosis: A Comprehensive Review

Sarcoidosis has innumerable clinical manifestations, as the disease may affect every body organ. Furthermore, the severity of sarcoidosis involvement may range from an asymptomatic state to a life-threatening condition. This manuscript reviews a wide variety of common and less common clinical characteristics of sarcoidosis. These manifestations are presented organ by organ, although additional sections describe systemic and multiorgan presentations of sarcoidosis. The lung is the organ most commonly involved with sarcoidosis with at least 90 % of sarcoidosis patients demonstrating lung involvement in most series. The skin, eye, liver, and peripheral lymph node are the next most commonly clinically involved organs in most series, with the frequency of involvement ranging from 10 to 30 %. The actual frequency of sarcoidosis organ involvement is probably much higher as it is frequently asymptomatic and may avoid detection. This is particularly common with lung, liver, cardiac, and bone involvement. Cardiac sarcoidosis is present in 25 % of all sarcoidosis but only causes clinical problems in 5 % of them. Nevertheless, unlike sarcoidosis involvement of most other organs, it may be suddenly fatal. Therefore, it is important to screen for cardiac sarcoidosis in all sarcoidosis patients. All sarcoidosis patients should also be screened for eye involvement as asymptomatic patients may have eye involvement that may cause permanent vision impairment. Pulmonary fibrosis from sarcoidosis is usually slowly progressive but may be life-threatening because of the development of respiratory failure, pulmonary hypertension, or hemoptysis related to a mycetoma or bronchiectasis. Some manifestations of sarcoidosis are not organ-specific and probably are the result of a release of mediators from the sarcoid granuloma. Two such manifestations include small fiber neuropathy and fatigue syndromes, and they are observed in a large percentage of patients.

Interrelationship between sleep-disordered breathing and sarcoidosis

Sleep-disordered breathing (SDB) has a high prevalence in sarcoidosis. This high prevalence may be the result of increased upper airways resistance from sarcoidosis of the upper respiratory tract, corticosteroid-induced obesity, or parenchymal lung involvement from sarcoidosis. OSA is a form of SDB that is particularly common in patients with sarcoidosis. Sarcoidosis and SDB share many similar symptoms and clinical findings, including fatigue, gas exchange abnormalities, and pulmonary hypertension (PH). Sarcoidosis-associated fatigue is a common entity for which stimulants may be beneficial. Sarcoidosis-associated fatigue is a diagnosis of exclusion that requires an evaluation for the possibility of OSA. Hypercapnia is unusual in a patient with sarcoidosis without severe pulmonary dysfunction and, in this situation, should prompt evaluation for alternative causes of hypercapnia, such as SDB. PH is usually mild when associated with OSA, whereas the severity of sarcoidosis-associated PH is related to the severity of sarcoidosis. PH caused by OSA usually responds to CPAP, whereas sarcoidosis-associated PH commonly requires the use of vasodilators. Management of OSA in sarcoidosis is problematic because corticosteroid treatment of sarcoidosis may worsen OSA. Aggressive efforts should be made to place the patient on the lowest effective dose of corticosteroids, which involves early consideration of corticosteroid-sparing agents. Because of the significant morbidity associated with SDB, early recognition and treatment of SDB in patients with sarcoidosis may improve their overall quality of life.

Worsening of pulmonary sarcoidosis

PURPOSE OF REVIEW

Despite the frequent occurrence of worsening pulmonary symptoms in pulmonary sarcoidosis patients, there is little available information concerning this topic.

RECENT FINDINGS

In this review, we outline the various causes for these symptoms. We propose to partition the various causes for these symptoms into specific categories.

SUMMARY

We believe that these categories will provide the clinician a framework to evaluate pulmonary sarcoidosis patients with such symptoms in a rigorous way that may be useful in optimizing their care.

Quality of Life Assessment in Sarcoidosis

Quantifying health-related quality of life (HRQL) and specific patient symptoms has developed to include rigorous techniques to develop patient-reported outcome measures (PROs). PROs may assess objectively the impact of a therapeutic intervention in a clinical sarcoidosis trial, and may be useful in following HRQL. Item response theory may lead to the construction of PROs that allow for the development of short forms, the PRO to be focused on specific areas along the continuum of the trait being studied, and the development of computer-adaptive testing where HRQL can be assessed accurately using very few items.

Neurologic manifestations of sarcoidosis

Neurologic manifestations occur in more than 5% of sarcoidosis patients and may be the presenting feature. Neurosarcoidosis can manifest in a myriad of ways including: cranial neuropathy, aseptic meningitis, mass lesions, encephalopathy, vasculopathy, seizures, hypothalamic-pituitary disorders, hydrocephalus, myelopathy, peripheral neuropathy, and myopathy. Because its etiology is unknown, its neurological manifestations are so diverse, and its diagnosis cannot be readily confirmed by laboratory tests, neurosarcoidosis poses many clinical problems. The diagnosis of neurosarcoidosis is usually based on the identification of characteristic neurologic findings in an individual with proven systemic sarcoidosis as established by clinical, imaging, or histologic findings. Although corticosteroids are regarded as the foundation of treatment, they are not always successful and have serious side-effects. Moreover, some patients with neurosarcoidosis are refractory to conventional therapy, and approximately 5-10% die. Optimal management of patients with neurosarcoidosis benefits from an understanding of the broad clinical spectrum of neurosarcoidosis, appreciation of the ways to best confirm a diagnosis, and awareness of the full range of treatment options, including the use of alternative therapies such as immunotherapy.

Neurosarcoidosis

OPINION STATEMENT

Neurosarcoidosis can involve either the central nervous system (CNS), the peripheral nervous system (PNS), or both. The clinical manifestations are varied and include cranial neuropathy, aseptic meningitis, hydrocephalus, headache, seizure, neuropsychiatric symptoms, neuroendocrine dysfunction, myelopathy, and peripheral neuropathy. Neurologic problems that develop in sarcoidosis patients should not be assumed to represent neurosarcoidosis, as they are often attributable to another cause. The diagnostic work up of neurosarcoidosis should include an evaluation for potential extra-neural involvement and histologic confirmation of sarcoidosis. If there is no appropriate extra-neurologic organ for biopsy, a biopsy from involved neural tissue needs to be considered. Biopsy of the dura and leptomeninges is less invasive than biopsy of the brain or spinal cord parenchyma. Gadolinium-enhanced magnetic resonance imaging (MRI) of the brain and spinal cord is the most sensitive test for neurosarcoidosis, while the diagnostic specificity of cerebrospinal fluid (CSF) analysis is limited. Corticosteroids are the mainstay of treatment for neurosarcoidosis. In general, oral corticosteroids are used for mild to moderate cases, while high-dose intravenous methylprednisolone is used in severe cases or refractory cases that fail to respond to oral corticosteroids. Immunomodulating and cytotoxic agents are often required for steroid-refractory neurosarcoidosis or for patients who develop significant corticosteroid adverse effects. Methotrexate is used as a first-line corticosteroid sparing agent. Tumor necrosis factor-alpha inhibitors, including infliximab, are effective for refractory neurosarcoidosis. Cyclophosphamide is also used for refractory neurosarcoidosis patients, but, because of the drug's significant toxicity, it is usually reserved for severe cases that have failed oral therapies when tumor necrosis factor alpha antagonists cannot be obtained. In addition to anti-granulomatous therapy, treatment is frequently required for neurosarcoidosis-associated conditions, such as epilepsy and neuroendocrine dysfunction. Surgical intervention is indicated for life threatening complications such as hydrocephalus, steroid-refractory spinal cord compression, or mass lesions causing increased intracranial pressure.

Psychiatric morbidity in chronic respiratory disorders in an Indian service using GMHAT/PC

OBJECTIVE

The study aimed to assess psychiatric morbidity in stable chronic respiratory disorders and to examine the pattern of psychiatric illness in specific respiratory disorders in Northern India.

METHODS

All consecutive patients with stable chronic respiratory illnesses who attended the respiratory disease clinic were recruited in the study. Their healthy attendants were interviewed as a control group. The research clinician, trained in the use of the Global Mental Health Assessment Tool, Primary Care Version (GMHAT/PC), interviewed all the participants. The respiratory consultant made the respiratory illness diagnosis. The data were analyzed comparing the patient and the control group by using relative risk and adjusted odds ratios.

RESULTS

Of 391 patients with respiratory illness, 44.8% had a mental illness identified by GMHAT/PC interview compared with 24.3% of 177 attendants (controls). Anxiety (20.6%), depression (13.2%) and obsessive compulsive disorders (4.6%) were the most frequently identified mental disorders in the respiratory disease group. Chronic obstructive pulmonary disease and bronchial asthma when combined with rhinitis had a significantly higher prevalence of comorbid mental illness than those illnesses alone.

CONCLUSION

Patients with chronic respiratory illness have high mental health comorbidity. Physicians and practitioners can be trained to identify mental illness using computer-assisted tools such as GMHAT/PC (which is easy to use by clinicians and well accepted by patients). A holistic approach of providing care to such patients may improve their overall outcome and quality of life.

Increased hospitalizations among sarcoidosis patients from 1998 to 2008: a population-based cohort study

Background

Diagnostic and treatment approaches for sarcoidosis have changed dramatically over the past decade. Yet, the most recent reports of trends in hospitalizations of sarcoidosis patients are over ten years old. The objectives of this study were to determine the incidence of sarcoidosis among hospitalized patients and to analyze recent trends and seasonality of hospitalizations in sarcoidosis patients.

Methods

We performed a retrospective cohort study of the Nationwide Inpatient Sample from 1998 through 2008. We identified all hospitalizations with a primary or secondary diagnosis of sarcoidosis (ICD-9-CM code 135). Incidence was modeled as a seasonal time series about a linear trend.

Results

Time series analysis of the monthly number of hospitalizations revealed a distinct positive linear trend. Over the study period, the number of hospitalized patients with sarcoidosis increased from 37,516 to 70,947 cases. Trends were most pronounced in patients older than 55 years (p < 0.0001), African Americans (p < 0.0001), females (p = 0.0289), and non-Medicaid populations (p < 0.0001). Hospitalizations are seasonal with highest incidence in January through March.

Conclusions

Hospitalizations among sarcoidosis patients have almost doubled during the past decade, with disproportionate rate increases in African Americans, women, and older patients. The rate also increases among patients with insurance other than Medicaid. This study indicates the need for heightened surveillance of sarcoidosis patients given the unknown consequences of evolving treatment approaches. Our results point to a need for research investigating risk factors for hospitalization, including medications, co-morbidities, demographics, and socioeconomic status.

Neurosarcoidosis: Clinical manifestations, diagnosis and treatment

Sarcoidosis is an idiopathic granulomatous disease affecting multiple organs. Neurosarcoidosis, involving the central and/or peripheral nervous systems, is a relatively rare form of sarcoidosis. Its clinical manifestations include cranial neuropathies, meningitis, neuroendocrinological dysfunction, hydrocephalus, seizures, neuropsychiatric symptoms, myelopathy and neuropathies. The diagnosis is problematic, especially when occurring as an isolated form without other organ involvement. Distinguishing neurosarcoidosis from other granulomatous diseases and multiple sclerosis is especially important. Although biopsy of neural tissue is the gold standard for the diagnosis of neurosarcoidosis, this is often not practical and the diagnosis must be inferred though other tests, often coupled with biopsy of extraneural organs. Corticosteroids and other immuno-suppressants are frequently used for the treatment of neurosarcoidosis. This article reviews the epidemiology, pathogenesis, pathology, clinical features, diagnosis, diagnostic tests, diagnostic criteria, and therapy of neurosarcoidosis.

Sarcoidosis: Psychotherapy and Long-Term Outcome—A Case Report

Sarcoidosis is a systemic, inflammatory disease of unknown aetiology, influenced by stressful life events and associated with a high incidence of alexithymic personality traits, and of depressive symptoms. The medical literature on sarcoidosis has called for a psychotherapeutic intervention to modify the perceived state of disease, the influence of stressful events and the depressive condition. Few studies have described cases treated with psychotherapy, and no information is available on its long-term outcome. We present the case of a patient with chronic sarcoidosis and periodical reacutizations with constantly pathological ESR. Twenty-four years after the diagnosis, a dynamic supportive-expressive psychotherapy for psychosomatic alexithymic patients was added to the medical therapy. At the beginning and at the end of the psychotherapy, and for the long-term outcome evaluations, Kellner's symptom questionnaire (SQ) was used to investigate psychological distress. The SQ scores, initially pathological, were normal at the end of the psychotherapy and for the following three years. Psychotherapy, without antidepressive drugs, resolved the depression. The depressive symptoms disappeared, along with the normalization and stabilization of the ESR. After three years, the outcome was positive. This is the first study describing a successful psychotherapy and its long-term outcome on a patient with sarcoidosis.

Types of fatigue in sarcoidosis patients

OBJECTIVE

Fatigue is frequently reported in sarcoidosis and appears to differ between patients. Three types of fatigue (Early Morning Fatigue, Intermittent Fatigue, and Afternoon Fatigue) are described in the literature for sarcoidosis, but have not been validated. Therefore, the aim of this study was to examine whether these types of fatigue can be identified in sarcoidosis.

METHODS

Outpatients (n=434) from Maastricht University Medical Centre participated in this study. Data were obtained from medical records. Patients also completed questionnaires regarding depressive symptoms, fatigue, quality of life, restless legs, dyspnea, depressive symptoms, anxiety, sleeping problems, symptoms indicative for small fiber neuropathy, and employment.

RESULTS

Latent Cluster Analysis revealed three clusters: 1) Mild Fatigue: patients with mild or no complaints of fatigue, 2) Intermittent Fatigue: patients with complaints of fatigue that varied during the day, and 3) All Day Fatigue: patients who felt tired the whole day. The three patient clusters differed regarding clinical, psychological, and demographical characteristics, with All Day Fatigue patients reporting the most complaints.

CONCLUSION

Intermittent fatigue was validated and two other types were found. Careful consideration to categorize patients with sarcoidosis in the three types of fatigue will help healthcare providers to understand the challenges these patients encounter. The usefulness of psychological counseling should be evaluated in future research in order to improve the wellbeing of the patients, especially for those with All Day Fatigue.

Sarcoidosis--scientific progress and clinical challenges

Sarcoidosis is an uncommon systemic inflammatory disorder characterized by noncaseating granulomatous inflammation that most commonly affects the lungs, intrathoracic lymph nodes, eyes and skin. One-third or more of patients with sarcoidosis have chronic, unremitting inflammation with progressive organ impairment. Findings of family and genetic studies indicate a genetic susceptibility to sarcoidosis, with genes in the MHC region having a dominant role. Immunologic hallmarks of the disease include highly polarized expression of cytokines produced by type 1 T helper cells and tumor necrosis factor (TNF) at sites of inflammation. Increasing evidence obtained within the past decade suggests the etiology of sarcoidosis predominantly involves microbial triggers, with the most convincing data implicating mycobacterial or propionibacterial organisms. Innate immune mechanisms, possibly involving misfolding and aggregation of serum amyloid A, might have a critical role in the pathobiology of sarcoidosis. Despite these advances, there are no clinically useful biomarkers that can assist the clinician in diagnosis, prognosis or assessment of treatment effects. Corticosteroids remain the cornerstone of therapy when organ function is threatened or progressively impaired. The role of immunosuppressive drugs and anti-TNF agents in the treatment of sarcoidosis remains uncertain, and there are no FDA-approved therapies. Meaningful progress in developing clinically useful tools and new therapies will depend on further advances in understanding the pathogenesis of sarcoidosis and its disease-specific pathways.

Gender differences in perception of dyspnea, assessment of control, and quality of life in asthma

BACKGROUND

There is limited information on the inter-relationship between gender, perception of dyspnoea and health-related quality of life (HRQoL) in asthma.

METHODS

In a cross-sectional study in an out-patient setting, 85 patients with bronchial asthma, 41 males and 44 females, underwent spirometry and were administered the following instruments to measure asthma control, HRQoL and dyspnoea : (a) Asthma control questionnaire (ACQ), (b) Asthma Quality of Life questionnaire (AQLQ), (c) Baseline dyspnoea index (BDI) questionnaire and Oxygen Cost Diagram (OCD).

RESULTS

Overall, male patients had greater airways obstruction but reported similar level of asthma control as females. Among patients with mild persistent asthma, females had a poorer level of control. The BDI and the OCD scores were significantly lower in female patients indicating greater dyspnoea and they also had a poorer quality of life especially in the symptoms and emotional domains of the AQLQ. After adjusting for the severity of airways obstruction in multivariate analysis, female gender and a poorer quality of life were independent predictors of increased perception of dyspnoea.

CONCLUSIONS

Female patients with asthma are likely to have a greater perception of dyspnoea, report a poorer control and have a poorer quality of life as compared to males. Female gender and a poorer quality of life are independent predictors of increased perception of dyspnoea in asthmatics.
