Endobronchial Ultrasound-guided Transbronchial Needle Aspiration versus Standard Bronchoscopic Modalities for Diagnosis of Sarcoidosis: A Meta-analysis. Chin Med J (Engl) 2016; 129:1607-15. [PMID: 27364799 PMCID: PMC4931269 DOI: 10.4103/0366-6999.184458] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2016] [Indexed: 11/04/2022] Open
Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an effective technique used to precisely detect enlarged mediastinal lymph nodes. The efficacy of EBUS-TBNA versus standard modalities for the diagnosis of sarcoidosis remains to be elucidated. In this meta-analysis, we compared the efficacies of these methods. METHODS We searched PubMed, Embase, The Cochrane Library, Wanfang, Cpvip, CNKI, and the bibliographies of the relevant references. We analyzed the data obtained with Revman 5.2 (Nordic Cochrane Center, Copenhagen, Denmark) and Stata 12.0 software (Stata Corporation, College Station, TX, USA). The Mantel-Haenszel method was used to calculate the pooled odds ratio (OR) and 95% confidence intervals (CIs). RESULTS Sixteen studies with a total of 1823 participants met the inclusion criteria, and data were extracted regarding the diagnostic yield of each approach. The ORs for EBUS-TBNA versus transbronchial lung biopsy (TBLB) for the diagnosis of sarcoidosis ranged from 0.26 to 126.58, and the pooled OR was 5.89 (95% CI, 2.20-15.79, P = 0.0004). These findings indicated that EBUS-TBNA provided a much higher diagnostic yield than TBLB. The pooled OR for EBUS-TBNA + TBLB + endobronchial biopsy (EBB) versus TBNA + TBLB + EBB was 1.54 (95% CI, 0.61-3.93, P = 0.36), implying that there was no significant difference between their diagnostic yields. However, clinical heterogeneity was reflected in the nature of the studies and in the operative variables. CONCLUSIONS The results of this meta-analysis suggest that EBUS-TBNA + TBLB + EBB could be used for the diagnosis of sarcoidosis, if available. At medical centers without EBUS-TBNA, TBNA + TBLB + EBB could be used instead.

Abstract
Sarcoidosis is a chronic multisystem disease with variable course resulting from the interaction between environmental factors and the immune system of individuals genetically predisposed. The evidence linking sarcoidosis with environmental triggers such as metals is increasing. We describe the case of a 44 year old female with a history. of smoking since age 30 and previous mercury dental filling who presented at physical examination with numerous subcutaneous nodules. Laboratory data showed accelerated erythrocyte sedimentation rate and high titer of anti-U1 ribonucleoprotein antibodies (U1 RNP). Skin biopsy and chest X-ray suggested the diagnosis of sarcoidosis. In this report we illustrate the different causes involved in the onset of sarcoidosis.

Abstract
Background. The aim of this study was to explore the possible association of the lung clearance of 99mTc- DTPA scan with HRCT lung abnormalities and with the pulmonary function tests [PFTs] in patients with sarcoidosis. Methods. We studied prospectively 15 patients [5 males, 10 females] of median age 46yr [range 27-67] with histologically proved sarcoidosis. HRCT scoring included the sum of the severity and extent of lymph node enlargement and parenchymal involvement. Results. The mean DTPA clearance half-time [Ï„ 1/2 <40 min] was found [mean [SD]] 38.3+4.5min. The lymph node enlargement was found 34% and the parenchymal involvement 12%. DTPA clearance was negatively correlated with the parenchymal involvement [r= -0.651, p=0.009]. The HRCT parenchymal abnormalities were found significantly correlated with PFTs [FVC [r= -0.65, p=0.008] and TLCO [r= -0.76, p=0.02]. Conclusions. Our data suggest a moderate association between 99mTc-DTPA scan and HRCT in pulmonary sarcoidosis. However, further studies in large scale of sarcoid patients are needed to clarify the role of this novel methodology in the evaluation and follow-up of this disorder.

Abstract
OBJECTIVE To characterize the epidemiology of sarcoidosis from 1946 through 2013. PATIENTS AND METHODS An inception cohort of patients with incident sarcoidosis from January 1, 1976, through December 31, 2013, in Olmsted County, Minnesota, was identified based on comprehensive individual medical record review. Inclusion required physician diagnosis supported by histopathologic confirmation, radiologic features of intrathoracic sarcoidosis, and a compatible clinical presentation. Data were collected on demographic characteristics, clinical presentation, laboratory investigations, and mortality. The data were augmented with a previously identified cohort of Olmsted County residents diagnosed as having sarcoidosis in 1946-1975. Incidence rates were age and sex adjusted to the 2010 US white population. RESULTS A total of 448 incident cases of sarcoidosis were identified (mean age, 44.2 years; 52% women). The annual incidence of sarcoidosis was 10.0 per 100,000 population. The incidence of sarcoidosis increased in women from 1950 to 1960, but otherwise there were no significant calendar year trends. However, the peak age at incidence for women shifted from 40 to 59 years in 1950 to 50 to 69 years in 2010. Similarly, the peak age at incidence for men shifted from 30 to 49 years in 1950 to 40 to 59 years in 2010. Ninety-seven percent of patients had intrathoracic involvement, but only 43% had respiratory symptoms. The overall mortality of patients with sarcoidosis was not different from that of the general population (standardized mortality ratio=0.90; 95% CI, 0.74-1.08). CONCLUSION Sarcoidosis occurred in approximately 10 persons per 100,000 per year. Most of the patients had intrathoracic involvement, although less than half had respiratory symptoms. Overall mortality was not different from that of the general population.

Abstract
BACKGROUND Clinically evidenced cardiac involvement in systemic sarcoidosis occurs in approximately 5% of patients, whereas post-mortem examinations identify cardiac sarcoidosis in over 60% of cases. OBJECTIVE Given the inconsistency of diagnostic approaches, we took aim at prospectively investigating the prevalence of cardiac sarcoidosis by cardiovascular magnetic resonance (CMR) in a primary Caucasian population and at correlating the results with standard clinical parameters. METHODS 188 patients with histologically proven sarcoidosis were included, provenient from the local pneumological department and a national sarcoidosis self-help association. All of them underwent CMR-imaging. Complementary 12-lead ECG, Holter monitoring, laboratory and pulmonary function testing were performed. RESULTS CMR-based diagnosis of cardiac sarcoidosis was made in 29 patients (15.4%), of whom 17 patients (9% of total cohort) exhibited increased relative gadolinium enhancement - reflecting acute inflammatory processes -, while 11 patients (5.9% of total cohort) showed late gadolinium enhancement as a marker for nonviable tissue damage. Both abnormalities were present in 1 patient (0.5%). Correlation analysis evinced significant association between CMR-diagnosed cardiac sarcoidosis and reduction in LVEF, increase in diastolic interventricular septal thickness, diastolic dysfunction as well as limited electrocardiographic abnormalities. Neither laboratory values nor pulmonary function parameters correlated with presence or activity of cardiac sarcoidosis. CONCLUSIONS Among our predominantly Caucasian sarcoidosis study population, CMR-detected cardiac affection occurred in 15.4% and was missed by internationally valid standard clinical testing in all but one case. It reinforces CMR's diagnostic value as modality of choice to evaluate cardiac sarcoidosis. The estimation of its prognostic potential and its value in assessing the incidence of cardiac sarcoidosis however requires further longitudinal investigation.

Abstract
BACKGROUND Chitotriosidase (CTO) was shown to be a good biomarker of sarcoidosis. Increased levels in bronchoalveolar lavage fluid (BALF) were reported and associated with more severe forms of the disease. OBJECTIVES The aim of the study was to evaluate the value of CTO in BALF as a routine biomarker of sarcoidosis. METHODS The study included 85 patients in 9 control subjects in whom serum and BALF CTO were measured. RESULTS Significantly higher CTO levels were detected in BALF of sarcoidosis patients than in control subjects (p < 0.001). There was good correlation between serum and BALF CTO levels in sarcoidosis patients (Spearman's Rho 0.481, p < 0.001). Serum but not BALF CTO had good correlation with clinical parameters. Only in a group of patients with BALF CTO above upper normal range there was association of BALF CTO with impaired FVC (p = 0.020) and chest radiograph score (0-2 vs. 3-4, p = 0.016). CONCLUSIONS In comparison to serum CTO no additional benefit of determining CTO in BAL for routine sarcoidosis workup was shown.

Abstract
BACKGROUND Sarcoidosis is a multisystem disease, with extrathoracic involvement occurring in 25-50% of patients. Multi-organ involvement is often associated with a more chronic and severe course. The value of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in diagnosing extrathoracic involvement in sarcoidosis has been demonstrated; however, because of the radiation dose and high cost, indications for its use must be well defined. Angiotensin-converting enzyme (ACE) is produced by active granuloma cells; thus, serum ACE (sACE) levels may reflect the total granuloma load. OBJECTIVES In this retrospective study, we evaluated the diagnostic value of sACE in the detection of extrathoracic involvement in sarcoidosis. METHODS 43 patients with biopsy-proven sarcoidosis underwent FDG-PET/CT during the initial workup. Positive findings were classified as thoracic and/or extrathoracic. The diagnostic value of sACE was estimated using sensitivity, specificity, and area under the receiver operating characteristic curves (AUCs). RESULTS Of the 43 patients studied, 17 (39.7%) had extrathoracic involvement. In this group, sACE values were higher than in patients without extrathoracic involvement (331 vs. 150, p=0.002) and correlated positively with extrathoracic involvement (R:0.532 p=0.02). Receiver operator characteristic curve analysis revealed an AUC of 0.816 [95% confidence interval: 0.669-0.963, p=0.002], 70.6% sensitivity and 80% specificity at the sACE cut-off value. CONCLUSIONS In sarcoidosis, extrathoracic involvement may be life threatening or indicative of poor outcome. sACE levels are easily determined and may predict extrathoracic involvement. In patients with sarcoidosis, sACE levels can be used to better define those who would benefit from FDG-PET/CT examination to detect extrathoracic involvement.

Abstract
Sarcoidosis is a systemic, inflammatory, granulomatous disease of unknown origin that can involve any organ. More than 90% of patients have thoracic sarcoidosis, which most frequently presents with bilateral hilar lymphadenopathy. In approximately 20% of patients with thoracic sarcoidosis there is involvement of the lung parenchyma as well as mostly asymptomatic cardiac sarcoidosis in up to 55% of patients. Most patients are asymptomatic and the diagnosis is an incidental finding on chest X-ray or during clarification of unspecific symptoms, such as fatigue or cough. In approximately two thirds of patients the disease undergoes spontaneous remission and in one third the disease follows a chronic or even progressive course. Furthermore, sarcoidosis can also be manifested in the abdominal organs, the central nervous system (CNS) and the musculoskeletal system. These manifestations are frequently subclinical and require targeted diagnostics when sarcoidosis is clinically suspected.

Abstract
Sarcoidosis is a rare multiorgan granulomatous disease of unknown etiology, mostly affecting young adults, with predilection for hilar lymph nodes and the lung. Despite clinical and histologic similarities between sarcoidosis and tuberculosis, the role of M. tuberculosis in the etiopathogenesis of sarcoidosis is still not clear. Over recent years numerous studies identifying peripheral blood T-cell response to various mycobacterial antigens were published. In parallel, there is no direct evidence for the role of alive M. tuberculosis in the development of sarcoidosis, as evidenced by negative culture in these patients. Exclusion of active tuberculosis as the granulomatous disease of known cause, still remain the important step in diagnostic work-up in sarcoidosis. Development of bronchoscopic techniques significantly reduced the number of surgical procedures. Combination of a few biopsy techniques: transbronchial needle aspiration, endobronchial biopsy and transbronchial lung biopsy, can achieve the optimum diagnostic yield. Because of the large percentage of spontaneous remission in sarcoidosis, the decision of treatment should be taken with caution. Corticosteroids still remain first-line therapy in sarcoidosis. Methotrexate is the most commonly used second-line drug. TNFα-antagonists are the therapeutic option in refractory sarcoidosis. In this article we summarise the present knowledge about the most common localization of sarcoidosis - pulmonary sarcoidosis, with special emphasis on the current etiologic hypothesis, possibility of diagnosis and treatment.

Abstract
Sarcoidosis is a systemic granulomatous disease of unknown etiology. Pulmonary involvement is common, but lung nodules in sarcoidosis are uncommon, and solitary nodules that cavitate are extremely rare. Nodular sarcoidosis is usually found in young, healthy, predominantly female individuals. These lesions need to be differentiated from multiple other conditions, including neoplasms and granulomatous infections. A thorough workup for other etiologies of cavitary lung lesions is required for diagnosis. Despite an ominous presentation, nodular cavitary sarcoidosis portends a favorable outcome. We report a patient who presented with a solitary cavitary nodular lung lesion that was diagnosed as sarcoidosis after extensive workup.

Abstract
PURPOSE To describe the ocular and systemic features in biopsy proven (definite) and non-biopsy proven (clinical) ocular sarcoidosis and to compare the ocular features with those proposed by the International Workshop for Ocular Sarcoidosis (IWOS). METHODS Retrospective chart review of 83 patients who attended a tertiary referral uveitis clinic and were diagnosed with sarcoidosis. Patients were divided into two groups based on the type of diagnosis: those who had tissue biopsy confirmed diagnosis 'definite sarcoidosis' (n= 42; 50.60 %) and those who had 'clinical sarcoidosis' (n= 41; 49.40%). Ocular and systemic manifestations, including lung function tests and bronchoalveolar lavage findings were compared in the two groups. The ocular features were also compared with the categories laid down by the International Workshop on Ocular Sarcoidosis (IWOS). RESULTS The mean age at presentation was 38.75 years (SD=12.33), 55.42% patients were female and mean follow-up was 24.35 months (SD=18.35). Trabecular meshwork nodules and/or tent-shaped PAS (category II of IWOS) were observed more frequently in patients with biopsy proven sarcoidosis (26.19 % v/s 9.76%; p=0.08). After logistic regression analysis, the predictor coefficient curve showed area under curve of 0.7262. Lymphocytosis (38.61% and 28.02%, p=0.93) and monocytosis (55.11% and 53.83%, p=0.56) on bronchoalveolar lavage analysis was present in both the groups, highlighting presence of granulomatous disease. CONCLUSION This study suggests high reliability for the clinical diagnosis of ocular sarcoidosis in patients with signs recommended by IWOS and that our diagnostic criteria are consistent with that of the IWOS.

Abstract
SETTING Sarcoidosis and tuberculosis share notable clinical, radiological, histological, and immunological similarities. The importance of vitamin D has long been investigated in these two granulomatous lung diseases. Cathelicidin is an antimicrobial peptide of the innate immune system, directly induced by vitD3. OBJECTIVE To evaluate the role of cathelicidin in sarcoidosis and tuberculosis development. DESIGN The study included 30 consecutive patients with active lung tuberculosis, 30 patients with sarcoidosis, and 20 healthy controls. 25-hydroxyvitamin D [25(OH)D] and cathelicidin levels were measured in blood samples. RESULTS Vitamin D levels were significantly higher (p<0.001) in tuberculosis patients (22.5 ± 9.96 ng/ml) than in sarcoidosis patients (11.75 ± 8.92 ng/ml). Severe vitamin D deficiency was as frequent as 47% in sarcoidosis patients compared to only 3% in tuberculosis patients. Cathelicidin levels were significantly higher in the control group (120.37 ± 41.03 pg/ml) than in sarcoidosis (67.68 ± 38.03 pg/ml) and tuberculosis (68.74 ± 39.44 pg/ml) patients (p<0.001). However, no significant difference in cathelicidin levels was observed between tuberculosis and sarcoidosis patients (p=0.966). The optimum cathelicidin cut-off value to distinguish sarcoidosis patients from healthy controls was 107.14 pg/ml (sensitivity 81.5%, specificity 71.2%). CONCLUSION Cathelicidin appears to play different roles in the development of granulomatous lung disease.

We studied mesenchymal-like cells as immunomodulators in chronic pulmonary sarcoidosis. METHODS PDA-001 cells were culture-expanded in vitro as a plastic-adherent, undifferentiated cell population that expresses the nominal phenotype CD34-, CD10+, CD105+ and CD200+. Four patients with refractory pulmonary sarcoidosis received two infusions of 150 million PDA-001 cells in 240 ml dextran-40 solution one week apart. During and for two hours after the first infusion, the pulmonary artery pressure was monitored. Prior to first infusion and within 24 hours after the second infusion, bronchoscopy and bronchoalveolar lavage (BAL) were performed. Patients underwent initial and serial pulmonary function testing and were followed for two years. RESULTS After the first infusion, all patients had a mild, non-clinically significant increase in mean pulmonary artery pressure, but none exhibited right heart failure or volume overload. In the year following treatment, there was no significant change in the FVC, but two patients had improvement in their chest x-ray and had prednisone withdrawn. BAL samples after the second infusion were sufficiently viable to undergo FACS analysis in three cases and in two patients, CD10+CD49c+C105+ cells (indicative of PDA-001 cells) were found. CONCLUSION The use of placental derived mesenchymal-like cells led to a mild increase in pulmonary artery pressure. In some cases, these cells were found in the BAL 24 hours after the second dose. Two of four patients demonstrated some steroid sparing benefit, including one patient with prolonged remission.

Estimation using the impulse oscillation system in patients with pulmonary sarcoidosis. SARCOIDOSIS, VASCULITIS, AND DIFFUSE LUNG DISEASES : OFFICIAL JOURNAL OF WASOG 2015; 32:144-150.

Abstract
BACKGROUND Limitations in airflow are detected in some patients with sarcoidosis in association with a poor prognosis. The impulse oscillation system (IOS) is used to treat patients with obstructive lung disease, as it can sensitively detect increased airway resistance. OBJECTIVES To investigate the characteristics of parameters obtained with IOS in patients with sarcoidosis. METHODS Forty-six pulmonary sarcoidosis patients at Chiba University Hospital and 20 healthy controls were enrolled. The subjects underwent IOS, pulmonary function testing and multidetector computed tomography. We evaluated the correlations between these indices in the pulmonary sarcoidosis patients and compared the pulmonary sarcoidosis patients with the healthy controls. RESULTS The ratio of V50/V25, percentage of wall area (WA%), resistance at 5 Hz (R5) and difference between the R5 and R20 (R5-R20) values of the patients with pulmonary sarcoidosis were significantly increased compared to those observed in the controls. Inverse weak correlations were observed between the R5-R20 values and the forced expiratory volume in one second (r = -0.56; p <0.001). The R5-R20 values were correlated with the V50/V25 (r = 0.42; p < 0.005) and WA% (r = 0.43; p < 0.05) values. The WA% values were also significantly correlated with the V50/V25 (r = 0.32; p < 0.05) and R5 (r = 0.33; p < 0.05) values. CONCLUSIONS IOS parameters were found to be significantly correlated with pulmonary function parameters and the airway wall thickness in pulmonary sarcoidosis patients. IOS is considered to be useful for detecting early manifestations of airflow limitation in pulmonary sarcoidosis patients.

Benefits of physical training in patients with idiopathic or end-stage sarcoidosis-related pulmonary fibrosis: a pilot study.

Abstract
BACKGROUND The natural history of disease in patients with stage IV (fibrotic) sarcoidosis may mirror that of patients with idiopathic pulmonary fibrosis (IPF). Both are bothered by progressive dyspnea, exercise limitation and fatigue. OBJECTIVE To establish whether patients suffering from pulmonary fibrosis might benefit from a physical training program. STUDY DESIGN Twenty-four eligible patients referred to the out-patient clinic of the ild care expertise team of Hospital Gelderse Vallei, Ede, The Netherlands between November 2012 and November 2013 were included in this observational pilot study of a 12-week physical training program. Outcomes, including exercise capacity, skeletal muscle strength, lung function and fatigue were assessed at two time points: 1) baseline; and 2) after completion of a 12-week physical training program. RESULTS At baseline, the percentage predicted DLCO, FVC, FEV1 and exercise capacity (assessed by six-minute walking distance (6MWD) or maximal oxygen uptake) was reduced in both groups. After program completion, exercise capacity improved (>10% improvement 6MWD) in 13 subjects (54.2%): 7 with IPF and 6 with sarcoidosis subjects. Other secondary endpoints, including pulmonary function tests and patient-reported outcome measures improved in some subjects. CONCLUSION A 12-week physical training program improved or maintained exercise capacity in patients with IPF (despite disease progression) or fibrotic sarcoidosis. The results from this pilot study could be used to design prospective studies aimed at answering lingering questions about exercise training in patients with these progressive, incurable conditions.

Abstract
BACKGROUND Sarcoidosis patients frequently experience fatigue, exercise intolerance and muscle weakness, resulting in reduced quality of life (QOL). Scientific studies on the benefits of physical training in sarcoidosis have been scarce, so the aim of this pilot study was to examine the impact of a 13-week physical training program on fatigue, physical functions and QOL in fatigued sarcoidosis patients and/or patients with exercise intolerance. METHODS 18 sarcoidosis patients participated in a 13-week physical training program. The Fatigue Assessment Scale (FAS), World Health Organization Quality of Life-BREF assessment instrument (WHOQOL-BREF),Medical Research Council (MRC) dyspnea scale, Visual Analogue Scale (VAS), six-minute walk test (6MWT), submaximal bicycle test and muscle strength of the quadriceps and elbow flexors were assessed at baseline and after the program. RESULTS FAS scores had decreased (mean difference -2.7 points, 95% CI -4.4 to -1.1) after completion of the training program, along with improvements in WHOQOLBREF psychological health domain (mean difference 0.9 points, 95% CI 0.2 to 1.7) and MRC dyspnea score (mean difference -0.4 points, 95% CI -0.8 to -0.1). 6MWD improved by 34.6 m (95% CI 20.3 to 49.0) and mean heart rate on the bicycle test improved (mean difference 8.4 beats/minute, 95% CI -13.8 to -3.0), as did quadriceps strength (mean difference 10.7 kg, 95% CI 5.5 to 15.9). CONCLUSION Fatigue reduced after a period of physical training in sarcoidosis patients. Moreover, psychological health and physical functions improved. Future studies are warranted to assess the benefits of physical training in sarcoidosis.

Abstract
UNLABELLED Sarcoidosis is a disease of unclear etiology, immunopathogenesis complex and diverse clinical course. AIM The aim of study was to evaluate the usefulness of CD34+ cells, CD4 and CD8 lymphocytes in peripheral blood for the diagnosis and better understanding of the sarcoidosis pathogenesis. MATERIALS AND METHODS The study included 40 patients (16 women and 24 men) aged 29-71 years (mean 45 years) with newly diagnosed pulmonary sarcoidosis. The control group consisted of 30 healthy subjects (18 women and 12 men) aged 24-65 years (mean 47 years). Tests were performed in peripheral blood, and lymphocytes CD4 and CD8 and progenitor CD34+ cells surface antigens were determined by flow cytometry. RESULTS It has been shown that number of CD34+ progenitor cells in peripheral blood was significantly higher in patients with newly diagnosed pulmonary sarcoidosis and showed a positive correlation with CD4/ CD8 rate. CONCLUSIONS CD34+ progenitor cells may be important in the pathogenesis of sarcoidosis. It is necessary to conduct further studies that identify heterogenous population of CD34+ cells with particular focus on fibrocytes.
