RESUMO
BACKGROUND: Serum biomarkers in the evaluation of organ involvement and prognostic monitoring of sarcoidosis have not been determined. The purpose of this study was to identify common biomarkers that could be used to assess organ involvement and monitor outcomes in sarcoidosis patients. METHODS: From Mar 2013 to Sep 2021, patients with newly diagnosed pulmonary sarcoidosis were enrolled in this study in Shanghai Pulmonary Hospital. The information from medical records was retrospectively collected including diagnosis, organ involvement, laboratory tests and follow up data. Differences of continuous variables between groups were analyzed by unpaired Student's t-test. Multivariate logistic regression model was performed to identify potential independent factors associated with multiple organ involvement. RESULTS: A total of 832 patients were included in the study. There were 339 (40.7%) patients with single organ pulmonary involvement, while 493 (59.3%) patients had two to seven organs involved. Among the routine serum tests, only the serum angiotensin converting enzyme (SACE) level was an independent factor of multiple organ involvement. Compared to those patients without involvement, SACE levels were higher in patients with extra-thoracic lymph node, skin, or spleen involvement as well as abnormal calcium metabolism. Interleukin-2 receptor (IL-2R) levels were higher in patients with extra-thoracic lymph node, spleen involvement and abnormal calcium metabolism than in those without it. The mean levels of SACE and IL-2R showed upward trends paralleling the increase on number of organs involved. In follow up, SACE and IL-2R levels were both decreased in an improved patient group, while there was no obvious difference was noticed before and after treatment in patients with persistent disease. CONCLUSION: SACE and IL-2R were useful as serum biomarkers in the initial evaluation of organ involvement as well as monitoring prognosis in sarcoidosis.

BACKGROUND: To explore if chest high-resolution computed tomography (HRCT) can make higher accurate stages for thoracic sarcoidosis stage than X-ray (CRX) only. METHODS: Clinical data from medical records of consecutive patients with a confirmed diagnosis of pulmonary sarcoidosis at Shanghai Pulmonary Hospital from January 1 2012 to December 31 2016 and consecutive patients treated at the Sarcoidosis Center of University of Cincinnati Medical Center, Ohio, USA from January 1 2010 to December 31 2015 were reviewed. The clinical records of 227 patients diagnosed with sarcoidosis (140 Chinese and 87 American) were reviewed. Their sarcoidosis stage was determined by three thoracic radiologists based on CXR and HRCT presentations, respectively. The stage determined from CXR was compared with that determined from HRCT. RESULTS: Overall, 50.2% patients showed discordant sarcoidosis stage between CXR and HRCT (52.9% in Chinese and 44.8% in American, respectively). The primary reason for inconsistent stage between CXR and HRCT was failure to detect mediastinal lymph node enlargement in the shadow of the heart in CXR (22.1%) and small nodules because of the limited resolution of CXR (56.6%). Stage determined from HRCT negatively correlated with carbon monoxide diffusing capacity (DLCO) significantly (P < .01) but stage determined from CXR did not. Pleural involvement was detected by HRCT in 58 (25.6%) patients but only in 17 patients (7.5%) by CXR. Patients with pleural involvement had significantly lower forced vital capacity and DLCO than patients without it (both P < .05). CONCLUSION: Revised staging criteria based on HRCT presentations included 5 stages with subtypes in the presence of pleural involvement were proposed. Thoracic sarcoidosis can be staged more accurately based on chest HRCT presentations than based on CXR presentations. Pleural involvement can be detected more accurately by HRCT.

BACKGROUND: The major reasons to treat sarcoidosis are to lower the morbidity and mortality risk or to improve quality of life (QoL). The indication for treatment varies depending on which manifestation is the cause of symptoms: lungs, heart, brain, skin or other manifestations. While glucocorticoids remain the first choice for initial treatment of symptomatic disease, prolonged use is associated with significant toxicity. Glucocorticoid-sparing alternatives are available. The presented treatment guidelines aim to provide guidance to physicians treating the very heterogenous sarcoidosis manifestations. METHODS: A European Respiratory Society Task Force committee composed of clinicians, methodologists and patients with experience in sarcoidosis developed recommendations based on the GRADE (Grading of Recommendations, Assessment, Development and Evaluations) methodology. The committee developed eight PICO (Patients, Intervention, Comparison, Outcomes) questions and these were used to make specific evidence-based recommendations. RESULTS: The Task Force committee delivered 12 recommendations for seven PICOs. These included treatment of pulmonary, cutaneous, cardiac and neurologic disease as well as fatigue. One PICO question regarding small-fibre neuropathy had insufficient evidence to support a recommendation. In addition to the recommendations, the committee provided information on how they use alternative treatments, when there was insufficient evidence to support a recommendation. CONCLUSIONS: There are many treatments available to treat sarcoidosis. Given the diverse nature of the disease, treatment decisions require an assessment of organ involvement, risk for significant morbidity, and impact on QoL of the disease and treatment.

PURPOSE OF REVIEW: There is a complex interaction between sarcoidosis and malignancy. Since tumors can elicit a granulomatous reaction, the presence of granulomas alone is insufficient to diagnose sarcoidosis in a patient with cancer. In addition, check point inhibitors can also lead to a granulomatous reaction which can be misdiagnosed as sarcoidosis. These issues need to be considered when exploring the relationship between sarcoidosis and malignancy. Despite these limitations, a growing amount of evidence supports the potential interaction of sarcoidosis and malignancy. RECENT FINDINGS: Several large epidemiologic studies of patients from Europe, the USA, and Japan reveal an increased relative risk for cancer in sarcoidosis patients. The highest relative risks are seen in patients with lymphoma and breast cancer. New criteria have been developed to standardize the diagnosis of sarcoidosis, which should further clarify the association. SUMMARY: The diagnosis of sarcoidosis may precede or occur after malignancy. In a sarcoidosis patient with an atypical lesion, such as a breast mass, a biopsy should be considered.

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.

PURPOSE: This study evaluates the prognostic significance of MST1R (RON) expression in breast cancer with respect to disease progression, long-term survival, subtype, and association with conventional prognostic factors. METHODS: The approach includes interrogation of survival and tumor staging with paired MST1R RNA expression from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets. Protein expression evaluation was performed using immunohistochemistry (IHC) staining of MST1R on breast cancer tissue samples from the Cancer Diagnosis Program Breast Cancer Progression tissue microarray and locally obtained breast tumor tissue samples analyzed with paired survival, metastasis, and subtype. RESULTS: Data from TCGA (n = 774) show poorer relapse-free survival (RFS) in patients with high MST1R expression (P = 0.32) and no difference in MST1R expression based on tumor stage (P = 0.77) or nodal status (P = 0.94). Patients in the GEO-derived Kaplan-Meier Plotter microarray dataset demonstrate the association of MST1R and poorer overall survival (n = 1402, P = 0.018) and RFS in patients receiving chemotherapy (n = 798, P = 0.041). Patients with high MST1R expression display worse overall survival (P = 0.01) and receiver operator characteristic (ROC) analysis demonstrate the predictive capacity of increased MST1R with early death (P = 0.0017) in IHC-stained samples. Paired IHC-stained breast tumor samples from the primary versus metastatic site show MST1R expression is associated with metastatic progression (P = 0.032), and ROC analysis supports the predictive capacity of MST1R in metastatic progression (P = 0.031). No associations of MST1R with estrogen receptor (ER), progesterone receptor (PR), both ER and PR, HER2 positivity, or triple-negativity were found (P = 0.386, P = 0.766, P = 0.746, P = 0.457, P = 0.947, respectively). CONCLUSIONS: MST1R expression has prognostic value in breast cancer with respect to survival and metastatic progression. MST1R expression is not associated with tumor stage, nodal status, or subtype.

INTRODUCTION: Sarcoidosis-associated pulmonary hypertension (SAPH) is associated with reduced survival in single-centre studies. The international Registry for SAPH (ReSAPH) with long-term follow-up was established to enrich our knowledge of this complication of sarcoidosis. This analysis aims to elucidate factors associated with reduced transplant-free survival in SAPH patients. METHODS: ReSAPH contains prospectively collected outcomes of SAPH patients since the time of registry enrolment. Information analysed includes right heart catheterisation data, pulmonary function testing, chest radiography, Scadding stage and 6-min walk distance (6MWD), among others. Cox regression models were used to identify independent predictors of transplant-free survival. RESULTS: Data from 215 patients followed for a mean±sd 2.5±1.9â years were available for analysis. In the 159 precapillary patients, the Kaplan-Meier-adjusted 1-, 3- and 5-year transplant-free survival was 89.2%, 71.7% and 62.0%, respectively. Kaplan-Meier-adjusted 1-, 3- and 5-year transplant-free survival in the incident group was 83.5%, 70.3% and 58.3%, respectively, and in the prevalent group was 94.7%, 72.2% and 66.3%, respectively. Patients with reduced diffusing capacity of the lung for carbon monoxide (D LCO) (<35% predicted) and 6MWD <300â m in the precapillary cohort had significantly worse transplant-free survival. Reduced 6MWD and preserved forced expiratory volume (FEV1)/forced vital capacity (FVC) ratio were identified as independent risk factors for reduced transplant-free survival in the precapillary cohort. CONCLUSION: Reduced D LCO (<35% pred) and 6MWD (<300â m) at the time of registry enrolment were associated with reduced transplant-free survival in the overall precapillary cohort. Preserved FEV1/FVC ratio was identified as an independent risk factor for worsened outcomes.

OBJECTIVES: Patients with advanced sarcoidosis often require third-line therapies including infliximab, adalimumab, rituximab, and repository corticotropin injection (RCI). Over time, some patients discontinue therapy. METHODS: In a retrospective review of patients at the University of Cincinnati Sarcoidosis Clinic, we identified patients who received one or more third-line treatments. Age, race, gender, organ involvement, and initial date of therapy were collected. For patients in whom a drug was discontinued, the last date of treatment, reason for drug discontinuation, and outcome of drug withdrawal were noted. RESULTS: Of the 2109 patients identified, 317 (15%) had received one or more third-line therapies (infliximab: 258 patients; adalimumab: 52 patients; rituximab: 34 patients; RCI: 101 patients). Patients with neurologic, cutaneous, or ocular sarcoidosis involvement were more likely to have received third-line therapy. Overall, 225 (50.6%) of treatment regimens were discontinued. Rate of discontinuation was higher for infliximab (55%), adalimumab (58%), or RCI (43%) than for rituximab (29%, Chi square=11.959, p=0.0075). Compared to RCI, the hazard ratio (HR) for discontinuing therapy due to infection was increased for infliximab (HR=12.14, p=0.0134) and adalimumab (HR=9.71, p=0.0356). The hazard ratio was higher for drug discontinuation due to allergic reactions to infliximab (HR=9.40, p=0.0017) or adalimumab (HR=5.83, p=0.0273). For patients receiving at least two years of therapy, drug survival was significantly shorter for infliximab compared to other therapies (Chi square=5.4054, p=0.0201). CONCLUSIONS: While third-line therapies are often initially effective, a significant number of patients discontinued individual treatments and initiated an alternative third-line therapy.

Abnormal calcium metabolism in sarcoidosis patients can lead to hypercalcemia, hypercalciuria, and kidney stones. Hypercalcemia in sarcoidosis is usually due to increased activity of 1α-hydroxylase in macrophages of pulmonary granulomata, resulting in low levels of 25-hydroxyvitamin D and high levels of calcitriol. Vitamin D supplementation may be dangerous for some sarcoidosis patients and is recommended only for those with decreased 25-hydroxyvitamin D and reduced or normal calcitriol level. Diagnosis, treatment of osteoporosis, and maintenance of bone health are complex issues for sarcoidosis patients. An approach to diagnosis and treatment of bone fragility is presented.

BACKGROUND: Premalignant breast lesions pose variable risks for transformation, raising the question who should receive treatment to counteract the potential progression to breast cancer. Because the secreted metastasis mediator Osteopontin (OPN) is a marker for breast cancer aggressiveness, its presence in these lesions may reflect progression risk. METHODS: By immunohistochemistry, we analyse the association of Osteopontin variant expression in healthy breasts, hyperplasias, papillomas, and carcinomas in situ from 434 women to assess a) staining for OPN exon 4 (present in OPN-a and OPN-b) or OPN-c in low-risk to high-risk lesions b) correlations between staining and progression (DCIS with invasion, invasive cancer) or survival. RESULTS: The markers correlate with risk, and they are prognostic for ensuing invasive disease and survival. About 10% of OPN-c pathology score 0-1 (intensity), vs. 40% of score 3 experience cancer over 5 years. More than 90% of women, who progress, had pathology scores of 2-3 for OPN-c intensity at the time of initial diagnosis. When combining OPN-c and OPN exon 4 staining, all of the low intensity patients are alive after 5 years, whereas women in the high category have a close to 30% chance to die within 5 years. Of patients who succumb, close to 80% had a high combined score at the time of initial diagnosis. CONCLUSION: The combined information of OPN splice variant immunohistochemistry can provide a foundation for very reliable prognostication and has the potential to aid decision making in the treatment of early breast lesions.

PURPOSE: The dose of repository corticotropin (RCI) and need for a loading dose in sarcoidosis patients receiving chronic corticosteroids are unclear. We performed a single-blind prospective study, comparing two doses of RCI in sarcoidosis. METHODS: Chronic pulmonary sarcoidosis patients receiving prednisone therapy with deterioration by 5% in FVC in the previous year were studied. RCI was administered subcutaneously at a loading dose of 80 units RCI for 10 days. Patients were randomized at day 14 to receive either 40- or 80-unit RCI twice a week. The dose of prednisone was modified by the clinician who was blinded to the patient's dosage of RCI. RESULTS: Sixteen patients completed the full 24 weeks of the study. At week 24, there was a decrease in the dose of prednisone, and improvements in DLCO, King's Sarcoidosis Questionnaire health status and fatigue score. There was no significant change in FVC % predicted. For the PET scan, there was a significant fall in the standard uptake value (SUV) of the lung lesions. Only 3/8 patients remained on 80 units RCI for full 24 weeks. There was no significant difference in the response to therapy for those treated with 40- versus 80-unit RCI. CONCLUSIONS: Repository corticotropin treatment was prednisone-sparing and associated with significant improvement in DLCO, PET scan, and patient-reported outcome measures. A dose of 40-unit RCI twice a week was as effective as 80-unit RCI and was better tolerated.

PURPOSE OF REVIEW: Several new agents have been investigated in sarcoidosis. As the outcome measures in these trials has varied, it is often difficult to compare different treatment regimens or to combine clinical trials of the same regimen. The present review will assess the various potential endpoints, including physiologic, chest imaging, and health-related quality of life. RECENT FINDINGS: Individual endpoints in pulmonary sarcoidosis trials have been studied and compared to response to several drugs. A panel of sarcoidosis experts as convened to enumerate the various potential endpoints and also voted on the relative importance of these endpoints as primary and secondary endpoints in sarcoidosis clinical trials. SUMMARY: There are several potential endpoints in clinical trials. These endpoints may also prove useful in clinical practice.

For treatment of sarcoidosis, one should develop a long-term management plan. Factors to be considered include the organ involvement and severity of symptoms. Different organ manifestations may require different treatments. Intensity of treatment is usually based on severity of disease or potential for organ failure or death. Glucocorticoids are quite effective as initial therapy for most forms of sarcoidosis. However, the toxicity associated with long-term treatment often leads to the use of alternative treatments. These include cytotoxic agents such as methotrexate, biologic agents such as the antitumor necrosis factor antibody infliximab, and other anti-inflammatory drugs such as hydroxychloroquine. In some cases, anti-inflammatory drugs may not help. Examples include pulmonary hypertension and fibrosis.

The hematologic system is frequently involved in sarcoidosis. Lymphopenia is the most common hematologic manifestation noted, although anemia and thrombocytopenia also occur. The etiology of these common manifestations can be direct granulomatous infiltration of bone marrow, lymph nodes, or spleen or related to immunologic dysfunction. Although not life threatening, these problems can lead to cytopenias requiring close monitoring in patients receiving a variety of disease treatments. The relationship between sarcoidosis and malignancy remains complex. However, some sarcoidosis patients are at increased risk for the development of malignancies, particularly lymphomas and gastrointestinal cancers. Conversely, cancer patients can experience an increase in the likelihood for the development of breast cancer and lymphomas.

INTRODUCTION: We present an updated overview of the hematological involvementassociated with sarcoidosis, including a management approach forcytopenias and revisiting the association with hematologicalmalignancies. AREAS COVERED: Theetiology of cytopenias in sarcoidosis can be attributed to two majoretiopathogenic mechanisms: infiltration of hematopoietic organs suchas the spleen and bone marrow, and autoimmune-mediated cytopenias.With respect to the association with hematological malignancies, itrequires careful evaluation of patients from a chronologicalperspective. Patients must be classified into one of three pathogenicscenarios, including preexisting hematological malignancies,synchronous development of malignancy and sarcoidosis due to commonpredisposing factors, or sarcoidosis as a predisposing factor formalignancies. EXPERT OPINION: The association between sarcoidosis and hematologic involvement isbest understood as a pathogenic continuum, with cytopenias andhematologic neoplasms intertwined due to various etiopathogenicmechanisms. These mechanisms include sarcoid infiltration ofhematopoietic organs, common predisposing immunogenetics for thedevelopment of autoimmune cytopenias and malignancies, and anincreased risk of neoplasm development in patients with autoimmunecytopenias. Collaboration among the main specialties involved in theclinical management of these patients is crucial for an earlymonitoring and management.

BACKGROUND: Different patterns of fibrosis on high-resolution CT scans (HRCT) have been associated with reduced survival in some interstitial lung diseases. Nothing is known about HRCT scan patterns and survival in sarcoidosis. RESEARCH QUESTION: Will a detailed description of the extent and pattern of HRCT scan fibrosis in patients with stage IV pulmonary sarcoidosis impact pulmonary function and survival? STUDY DESIGN AND METHODS: Two hundred forty patients with stage IV sarcoidosis at two large tertiary institutions were studied. The earliest HRCT scan with fibrosis was reviewed for extent of fibrosis (< 10%, 10%-20%, and > 20%) and presence of bronchiectasis, upper lobe fibrocystic changes, basal subpleural honeycombing, ground-glass opacities (GGOs), large bullae, and mycetomas. Presence of sarcoidosis-associated pulmonary hypertension (SAPH) and pulmonary function testing performed within 1 year of HRCT were recorded. Patients were followed up until last clinic visit, death, or lung transplantation. RESULTS: The mean age was 58.4 years. Seventy-four percent were Black, 63% were female, and mean follow-up was 7.4 years. Death or LT occurred in 53 patients (22%). Thirty-one percent had > 20% fibrosis, 25% had 10%-20% fibrosis, and 44% had < 10% fibrosis. The most common HRCT abnormalities were bronchiectasis (76%), upper lobe fibrocystic changes (36%), and GGOs (28%). Twelve percent had basal subpleural honeycombing, and 32% had SAPH. Patients with > 20% fibrosis had more severe pulmonary impairment, were more likely to have SAPH (53%), and had worse survival (44% mortality; P < .001). Upper lobe fibrocystic changes, basal subpleural honeycombing, and large bullae were associated with worse pulmonary function and worse survival. Patients with basal subpleural honeycombing had the worst pulmonary function and survival (55% mortality; P < .001). GGOs were associated with worse pulmonary function but not worse survival, and mycetomas were associated with worse survival but not worse pulmonary function. A Cox proportional hazards model indicated that basal subpleural honeycombing (hazard ratio, 7.95), diffusion capacity for carbon monoxide < 40% (HR, 5.67) and White race (hazard ratio, 2.61) were independent predictors of reduced survival. INTERPRETATION: HRCT scan features of fibrotic pulmonary sarcoidosis had an impact on pulmonary function and survival. Presence of >20% fibrosis and basal subpleural honeycombing are predictive of worse pulmonary function and worse survival in patients with stage IV pulmonary sarcoidosis.

BACKGROUND: The Sarcoidosis Diagnostic Score (SDS) system has been established for sarcoidosis patients based on the WASOG organ involvement criteria. We evaluated modifications of the SDS system to determine if they improved its the diagnostic accuracy. METHODS: Biopsy-confirmed patients with sarcoidosis seen during a 7-month period at 9 sarcoidosis centers across the world. Patients with non-sarcoidosis seen at the same sites were served as control patients. Comparing the SDS-biopsy and SDS-clinical values of five groups: duration of symptoms prior to evaluation (≤1 years vs.>1 years, ≤2 years vs.>2 years), organ involvement (lung, eye, or cardiac), race, and sex. RESULTS: A total of 990 patients with sarcoidosis and 1011 controls were included in this study. The SDS-clinical was significantly more discriminating for those undergoing assessment with symptoms for more than one year (z-statistic=2.570, p = 0.0102) or two years (z-statistic=2.546, p = 0.0109). However, the addition of two points for both >1 years and >2 years since onset of symptoms did not increase sensitivity and specificity of diagnosis with the SDS system. The SDS-clinical cut-off for patients with ocular or cardiac disease was two points higher than that for lung disease. There was no difference in SDS-clinical or biopsy AUC values based on gender or race. CONCLUSIONS: The longer the duration of symptoms prior to diagnosis, the more likely the diagnosis of sarcoidosis was correct. For patients presenting with ocular or cardiac symptoms, evidence of multi-organ involved can improve the diagnostic accuracy of the SDS-clinical.
RESUMO
The treatment options for pulmonary sarcoidosis have increased over the past 10 years. As new treatments have been introduced, the best way to assess and compare treatments remains unknown. The goal of this review is to discuss the standard treatments for pulmonary sarcoidosis, including glucocorticoids, and cytotoxic agents, such as methotrexate, azathioprine and leflunomide, and compare them to the newer biological agents, such as infliximab and adalimumab. We also discuss some novel treatments which are currently being evaluated. To compare these different regimens, we look at the measures used to assess response. These include pulmonary function, chest imaging, steroid sparing potential and, more recently, improvements in quality of life measures. While there is, as yet, no standard assessment for response, there is a growing consensus that response to treatment may include improvement of one or more of the following: forced vital capacity, chest imaging and steroid sparing. Several drugs used for pulmonary sarcoidosis have demonstrated improvement in one or more of these measures.

Rationale: The Sarcoidosis Diagnostic Score (SDS) has been established to quantitate the clinical features consistent with sarcoidosis in a monocentric study. Objectives: We aimed to confirm the diagnostic value of SDS in a large, multicontinental study and to assess the utility of SDS in differentiating sarcoidosis from alternative diagnoses, including infectious and noninfectious granulomatous diseases. Methods: We included patients with biopsy-confirmed sarcoidosis at nine centers across the world. Patients without sarcoidosis seen at the same sites served as control patients. Using a modified World Association of Sarcoidosis and Other Granulomatous Disorders organ assessment instrument, we scored all patients for the presence of granuloma on biopsy, highly probable symptoms, and least probable symptoms for each area. Two sarcoidosis scores were generated: SDS Biopsy (with biopsy) and SDS Clinical (without biopsy). SDS Clinical and Biopsy were calculated for all patients. We calculated and compared the area under the curve (AUC) for SDS Clinical and Biopsy according to different diagnosis scenarios. Results: A total of 1,041 patients with sarcoidosis and 1,035 without sarcoidosis were included. The results for SDS Clinical (AUC, 0.888; 95% confidence interval [CI], 0.874-0.902) and SDS Biopsy (AUC, 0.979; 95% CI, 0.973-0.985) according to AUC were good to excellent for differentiating sarcoidosis from alternative diagnosis. SDS Clinical was less discriminatory in males (P = 0.01) and in high tuberculosis prevalence centers (P < 0.001). However, SDS Clinical (AUC, 0.684; 95% CI, 0.602-0.766) and SDS Biopsy (AUC, 0.754; 95% CI, 0.673-0.835) were not sufficiently discriminative for noninfectious granulomatous diseases, but both SDSs could differentiate sarcoidosis from infectious granulomatous diseases. Algorithms were proposed for the SDS Clinical and SDS Biopsy to assist the clinician in the diagnostic process, and cutoff values were proposed for the SDS Clinical and SDS Biopsy, allowing the diagnosis of sarcoidosis to be safely confirmed or rejected in most cases except for noninfectious granulomatous disease. Conclusions: This multicontinental study confirms that both SDS Clinical and SDS Biopsy have good to excellent performance in discriminating sarcoidosis from alternative diagnoses. Differences in the AUC were seen for high tuberculosis prevalence versus low tuberculosis prevalence centers and for males versus females. Both SDSs had good discriminatory function for infectious granulomatous disease but failed in cases of noninfectious granulomatous disease such as berylliosis.

BACKGROUND: Individuals with self-declared sarcoidosis are at increased risk of COVID-19 related morbidity and mortality for which vaccination can be lifesaving. Despite this, vaccine hesitancy remains a large barrier to global acceptance of vaccination against COVID-19. We aimed to identify individuals with sarcoidosis who had and had not been vaccinated against COVID-19 vaccine to 1) establish a safety profile of COVID-19 vaccination in those with sarcoidosis and 2) to elucidate factors that contribute to COVID-19 vaccine hesitancy. METHODS: A questionnaire inquiring about COVID-19 vaccination status, vaccination side effects, and willingness for future vaccination was distributed from December 2020 to May 2021 to individuals with sarcoidosis living in the US and European countries. Details regarding sarcoidosis manifestations and treatment were solicited. Vaccine attitudes were classified as pro or anti-COVID-19 vaccination for subgroup analysis. RESULTS: At the time of questionnaire administration, 42% of respondents had already received a COVID-19 vaccination, most of whom either denied side effects or reported a local reaction only. Those off sarcoidosis therapy were more likely to report systemic side effects. Among subjects who had not yet received a COVID-19 vaccine, 27% of individuals reported they would not receive one once available. Reasons against vaccination were overwhelmingly related to the lack of confidence in vaccine safety and/or efficacy and less related to concerns associated with convenience or complacency. Black individuals, women, and younger adults were more likely to decline vaccination. CONCLUSIONS: Among individuals with sarcoidosis, COVID-19 vaccination is well-accepted and well-tolerated. Subjects on sarcoidosis therapy reported significantly less vaccination side effects, and thus the correlation between side effects, vaccine type, and vaccine efficacy requires further investigation. Strategies to improve vaccination should focus on improving knowledge and education regarding vaccine safety and efficacy, as well as targeting sources of misinformation, particularly in young, black, and female subpopulations.
