Health-Related Quality of Life in Sarcoidosis

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.

"The chameleon among diseases" - an explorative view of sarcoidosis and identification of the consequences for affected patients and relatives using qualitative interviews

INTRODUCTION

Sarcoidosis is a multisystemic disease, with the lungs being the main site of manifestation. Although the exact etiology remains unclear, both genetic and environmental factors are being discussed. Diagnostic evaluation is challenging, and the management of chronic patients and assessment of their needs proves difficult, especially in the absence of targeted therapy. Studies on sarcoidosis patients have shown that quality of life is limited even after clinically measurable parameters have resolved. The question remains how patients and their relatives perceive medical care and the diagnostic process and how these affect their well-being.

METHODS

Qualitative, semi-structured interviews were conducted with patients and their relatives between September 2019 and February 2020. Interviews were recorded, transcribed verbatim, and analyzed using qualitative content analysis. Deductive hypotheses were then formed based on categories according to personal aspects, symptoms, diagnostic, daily life activity, therapy, psychological aspects and wishes.

RESULTS

Fourteen patients and five relatives were included. Most patients reported subacute symptoms before the first organ-related episode. A high degree of personal initiative was required from the majority of respondents in both the diagnostic and subsequent therapeutic processes. In addition, respondents reported so-called "doctor-hopping", a lack of specialists or contacts, and a lack of medical support. The Internet and self-help groups played a fundamental role for patients and relatives in exchanging information with other affected persons and to compensate for an existing information deficit.

CONCLUSION

The results provide new insights into patients' and relatives' perceptions of the sarcoidosis diagnosis and treatment process. Identification of barriers such as a lack of physicians and an information deficit highlights potential targets for strategies to optimize sarcoidosis management.

Health-related quality of life in cardiac sarcoidosis: a systematic review

People living with cardiac sarcoidosis (CS) are likely to have worse clinical outcomes and greater impairment on health-related quality of life (HRQoL) than other sarcoidosis manifestations. CS can result in a constellation of intrusive symptoms (such as palpitations, dizziness, syncope/pre-syncope, chest pain, dyspnoea, orthopnoea, or peripheral oedema) and/or life-threatening episodes, requiring consideration of invasive cardiac procedures for diagnosis and for the management of acute events. Additionally, the presence of multisystemic involvement and persistent non-specific sarcoidosis symptoms negatively affect HRQoL. A systematic review was undertaken to explore the impact of CS on HRQoL in adults with CS. Multiple bibliographic databases were searched for studies with HRQoL as primary or secondary outcomes in CS (PROSPERO registration: CRD42019119752). Data extraction and quality assessments were undertaken independently by two authors. From the initial 1609 identified records, only 11 studies included CS patients but none specifically reported HRQoL scores for CS patients. The average representation of CS patients was 14.5% within these cohorts (range 2-22%). The majority (73%) was conducted in single-centre tertiary care settings, and only one study (9%) included longitudinal HRQoL data. CS patients were among those sarcoidosis patients with impaired HRQoL and worse outcomes, requiring higher doses of sarcoidosis-specific therapy which contribute to further deterioration of HRQoL. Sarcoidosis studies do not incorporate stratified HRQoL scores for CS patients. While there is a need for longitudinal and multicentre studies assessing HRQoL outcomes in CS cohorts, the development of CS-specific tools is also needed.

Sarcoidosis: Updates on therapeutic drug trials and novel treatment approaches

Sarcoidosis is a systemic granulomatous inflammatory disease of unknown etiology. It affects the lungs in over 90% of patients yet extra-pulmonary and multi-organ involvement is common. Spontaneous remission of disease occurs commonly, nonetheless, over 50% of patients will require treatment and up to 30% of patients will develop a chronic progressive non-remitting disease with marked pulmonary fibrosis leading to significant morbidity and death. Guidelines outlining an immunosuppressive treatment approach to sarcoidosis were recently published, however, the strength of evidence behind many of the guideline recommended drugs is weak. None of the drugs currently used for the treatment of sarcoidosis have been rigorously studied and prescription of these drugs is often based on off-label” indications informed by experience with other diseases. Indeed, only two medications [prednisone and repository corticotropin (RCI) injection] currently used in the treatment of sarcoidosis are approved by the United States Food and Drug Administration. This situation results in significant reimbursement challenges especially for the more advanced (and often more effective) drugs that are favored for severe and refractory forms of disease causing an over-reliance on corticosteroids known to be associated with significant dose and duration dependent toxicities. This past decade has seen a renewed interest in developing new drugs and exploring novel therapeutic pathways for the treatment of sarcoidosis. Several of these trials are active randomized controlled trials (RCTs) designed to recruit relatively large numbers of patients with a goal to determine the safety, efficacy, and tolerability of these new molecules and therapeutic approaches. While it is an exciting time, it is also necessary to exercise caution. Resources including research dollars and most importantly, patient populations available for trials are limited and thus necessitate that several of the challenges facing drug trials and drug development in sarcoidosis are addressed. This will ensure that currently available resources are judiciously utilized. Our paper reviews the ongoing and anticipated drug trials in sarcoidosis and addresses the challenges facing these and future trials. We also review several recently completed trials and draw lessons that should be applied in future.

Rationale and design of the SARCoidosis Outcomes in all respiratory Viral Infectious Diseases (SARCOVID) Study

INTRODUCTION

Respiratory infections are ubiquitous. The COVID-19 pandemic has refocused our attention on how morbid and potentially fatal they can be, and how host factors have an impact on the clinical course and outcomes. Due to a range of vulnerabilities, patients with sarcoidosis may be at higher risk of poor outcomes from respiratory infections. The objective of the SARCoidosis Outcomes in all respiratory Viral Infectious Diseases (SARCOVID) Study is to determine the short-term and long-term impacts of respiratory viral illnesses (COVID-19 and non-COVID-19) in sarcoidosis.

METHODS AND ANALYSIS

Up to 20 clinical sites across the USA are participating in the recruitment of 2000 patients for this observational, prospective study. To ensure that the study cohort is representative of the general population with sarcoidosis, participating sites include those dedicated to reaching under-represented minorities or patients from non-urban areas. Baseline data on demographic features, comorbidities, sarcoidosis characteristics and pre-enrolment lung function will be captured at study entry. During this 3-year study, all acute respiratory infectious events (from SARS-CoV-2 and any other respiratory pathogen) will be assessed and recorded at quarterly intervals. The level of required medical care and survival outcomes determine infection severity, and the impact of infection on quality of life measures will be recorded. Post-infection lung function and imaging results will measure the long-term impact on the trajectory of sarcoidosis. Patients will be analysed according to the clinical phenotypes of cardiac and fibrotic pulmonary sarcoidosis. Control groups include non-infected patients with sarcoidosis and patients with non-sarcoidosis interstitial lung disease.

ETHICS AND DISSEMINATION

Each site received local institutional review board approval prior to enrolling patients, with the consent process determined by local institution standards. Data will be published in a timely manner (goal <12 months) at the conclusion of the 3-year follow-up period and will be made available upon request.

Ageing with Interstitial lung disease: preserving health and well being

PURPOSE OF REVIEW

Ageing, the accrual of molecular and cellular damage over a lifetime confers progressive physiologic dysfunction of bodily systems, leaving the body in a heightened state of vulnerability to biophysical and psychosocial stressors. The inflection point is frailty which easily leads to disability and death. Interstitial lung disease (ILD) creates biophysical and psychosocial stresses difficult for even optimally fit patients to cope with. With evolving ILD treatment pathways, people with ILD are living longer.

RECENT FINDINGS

ILD and ageing are bi-directionally influential: ILD, its treatments, complications, and collateral systemic extra-pulmonary damage (hypoxic and oxidative stress) wear on the ageing person and ageing impacts a person's tolerance of ILD. ILD extent may proportionally accelerate age-related vulnerabilities. ILD related to inflammatory systemic diseases, e.g. connective tissue diseases or sarcoidosis, exert an even more complex biophysical impact on the body.

SUMMARY

The present review stresses goals of preventing frailty in ILD and preserving general health and well being of people living with ILD of any age, from time of diagnosis and as they age. The development of a prediction score is proposed to classify those at risk of frailty and guide interventions that preserve successful ageing for all levels of ILD severity.

The Value of a Patient Global Assessment in Management of Sarcoidosis

The patient global assessment (PGA) is a reported outcome instrument used to gauge the patient's well-being. We performed a prospective study of patients seen at the University of Cincinnati Sarcoidosis Clinic. Two groups were studied: those at first visit during the time period (initial) and those seen at least one more time by the same physician (follow-up). A total of 1006, including 677 initial, visits occurred during the six-month period. Patients in whom anti-inflammatory treatment was initiated or increased had a significantly lower PGA score (ANOVA p < 0.001, p < 0.05 for increased versus all others). There was no significant difference in initial PGA score based on race, sex, or age. The change in PGA was significantly lower for patients in whom treatment was increased (ANOVA p < 0.001, increased different from all others, p < 0.05). The PGA was significantly lower for patients in whom anti-inflammatory therapy was increased; however, there was overlap between groups.

Assessment of dyspnea in sarcoidosis using the Baseline Dyspnea Index (BDI) and the Transition Dyspnea Index (TDI)

INTRODUCTION

The Borg and Modified Medical Research Council (mMRC) dyspnea scales have been used to evaluate dyspnea in sarcoidosis. The Baseline Dyspnea Index (BDI) and Transitional Dyspnea Index (TDI) are useful for the assessment of dyspnea in COPD. It is not known if the BDI-TDI accurately assesses dyspnea in sarcoidosis patients.

METHODS

Data was analyzed from the Registry for Advanced Sarcoidosis (ReAS), a multi-national database enrolling patients with advanced sarcoidosis and a comparison group of sarcoidosis patients with non-advanced disease. At baseline, patients completed a BDI questionnaire along with spirometry, 6-min walk distance (6MWD), mMRC, Borg score, fatigue assessment score (FAS) and HRQoL assessments using Kings Sarcoidosis Questionnaire (KSQ) and St Georges Respiratory Questionnaire (SGRQ). At 12-months, patients with advanced disease completed a TDI questionnaire along with the other measures. Correlations between BDI and baseline variables, and between TDI and changes in baseline variables were evaluated.

RESULTS

There was significant correlation (p < 0.001 for all) between BDI and baseline 6MWD (rho = 0.336), FVC% (rho = 0.387), FEV1% (rho = 0.285), DLCO% (rho = 0.355), mMRC (rho = -0.721), Borg score (rho = -0.389), FAS (rho = -0.669), SGRQ (rho = -0.785), and KSQ (rho = 0.318 to 0.724). At follow-up, TDI correlated with BDI, but not with changes in pulmonary function or other dyspnea measures.

CONCLUSION

BDI scores correlated with pulmonary function, 6MWD, and other dyspnea measures. TDI scores did not correlate with changes in pulmonary function or other dyspnea measures. BDI may be a useful independent measure of dyspnea in sarcoidosis patients. The role of TDI needs further evaluation in longitudinal studies associated with changes in clinical parameters.

Biologic and advanced immunomodulating therapeutic options for sarcoidosis: a clinical update

Introduction: Sarcoidosis is a multi-organ disease with a wide range of clinical manifestations and outcomes. A quarter of sarcoidosis patients require long-term treatment for chronic disease. In this group, corticosteroids and cytotoxic agents be insufficient to control diseaseAreas covered: Several biologic agents have been studied for treatment of chronic pulmonary and extra-pulmonary disease. A review of the available literature was performed searching PubMed and an expert opinion regarding specific therapy was developed.Expert opinion: These agents have the potential of treating patients who have progressive disease. Many of these agents have different mechanisms of action, response rates, and toxicity profiles.
