Abstract
INTRODUCTION Many patients with interstitial lung diseases (ILDs), especially fibrotic ILDs, experience chronic cough. It negatively impacts both physical and psychological well-being. Effective treatment options are limited. AREAS COVERED The pathophysiology of chronic cough in IPF is complex and involves multiple mechanisms, including mechanical distortion of airways, parenchyma, and nerve fibers. The pathophysiology of cough in other fibrosing ILDs is poorly understood and involves various pathways. The purpose of this review is to highlight mechanisms of chronic cough and to present therapeutic evidence for its management in the most commonly occurring diffuse fibrosing lung diseases including idiopathic pulmonary fibrosis (IPF), connective tissue disease-related interstitial lung disease (CTD-ILD), sarcoidosis-related ILD (Sc-ILD), chronic hypersensitivity pneumonitis-related ILD (CHP-ILD), and post-COVID-19-related interstitial lung disease (PC-ILD). EXPERT OPINION This review guides the management of chronic cough in fibrosing ILDs. In this era of precision medicine, chronic cough management should be individualized in each interstitial lung disease.

Abstract
Sarcoidosis is a systemic inflammatory disease of unknown etiology, which mainly affects the lungs and lymph nodes, as well as extrapulmonary organs. Its incidence, and prevalence rate, and disease course largely vary with regions and populations globally. The clinical manifestations of sarcoidosis depend on the affected organs and the degree of severity, and the diagnosis is mainly based on serum biomarkers, radiographic, magnetic resonance, or positron emission tomography imaging, and pathological biopsy. Noncaseating granulomas composing T cells, macrophages, epithelioid cells, and giant cells, were observed in a pathological biopsy, which was the characteristic pathological manifestation of sarcoidosis. Angiotensin-converting enzyme (ACE) was first found in the renin-angiotensin-aldosterone system. Its main function is to convert angiotensin I (Ang I) into Ang II, which plays an important role in regulating blood pressure. Also, an ACE insertion/deletion polymorphism exists in the human genome, which is involved in the occurrence and development of many diseases, including hypertension, heart failure, and sarcoidosis. The serum ACE level, most commonly used as a biomarker in diagnosing sarcoidosis, in patients with sarcoidosis increases. because of epithelioid cells and giant cells of sarcoid granuloma expressing ACE. Thus, it serves as the most commonly used biomarker in the diagnosis of sarcoidosis and also aids in analyzing its therapeutic effect and prognosis in patients with sarcoidosis.

Abstract
Sarcoidosis is a rare cause of cardiomyopathy that can easily be confused for acute heart failure when pulmonary manifestations are absent. We present the case of a 41-year-old female presenting with dyspnea found to have ventricular arrhythmia on arrival at the emergency department. Cardiac magnetic resonance and computed tomography of the chest with contrast were performed, confirming the systemic sarcoidosis diagnosis with cardiac involvement.

Abstract
Cardiac sarcoidosis (CS) can be silent in most patients with extrapulmonary sarcoidosis. Atrioventricular (AV) block is the most common clinical presentation, but it can also present as fatal ventricular arrhythmias and sudden cardiac death. Endomyocardial biopsy is the gold standard; however, it is not sensitive since CS can involve the myocardium in a patchy distribution. Our case depicts a female who presented with syncope; however, her hospital course was complicated by multiple cardiac arrests. Her initial laboratory tests, including an autoimmune workup, were unremarkable. Cardiac magnetic resonance and fluorodeoxyglucose (FDG) positron emission tomography (PET) imaging revealed intramyocardial delayed enhancement of the basal anteroseptal (non-ischemic distribution) and patchy foci of increased uptake in the anteroseptal and inferior myocardial region, respectively. The patient was started on intravenous methylprednisolone, and her condition slowly improved. Post-discharge, the patient followed in the outpatient clinic with a repeat FDG-PET scan revealing resolution of myocardial FDG uptake. She also underwent bronchoscopy with lymph node biopsy showing granulomas and endobronchial biopsy confirming pulmonary sarcoidosis.

Abstract
Although corticosteroids are the standard first-line therapy for pulmonary sarcoidosis, long-term and high-dose use of these drugs are associated with increased risk of adverse events and high healthcare utilization costs. Treatment guidelines for pulmonary sarcoidosis indicate that off-label immunomodulators and biologics may be warranted for severe disease. Repository corticotropin injection (RCI, Acthar® Gel), a complex mixture of adrenocorticotropic hormone analogs and other pituitary peptides, is one of only two therapies approved by the US Food and Drug Administration for symptomatic pulmonary sarcoidosis and is recommended by current European Respiratory Society treatment guidelines for use on a case-by-case basis. With its unique anti-inflammatory and immunomodulatory mechanism of action through activation of melanocortin receptors in various cell types, RCI has demonstrated steroid-sparing properties. RCI has a long history of use in autoimmune and inflammatory disorders, with proven safety and efficacy for pulmonary sarcoidosis. In this narrative review, we present the clinical evidence for the safety and efficacy of RCI in the treatment of pulmonary sarcoidosis, identify where RCI falls within the current treatment guidelines, and describe the unique mechanism of action of RCI for promoting anti-inflammatory and immunomodulatory effects.

Symptoms, impacts, and suitability of the Pulmonary Arterial Hypertension-Symptoms and Impact (PAH-SYMPACT™) questionnaire in patients with sarcoidosis-associated pulmonary hypertension (SAPH): a qualitative interview study. BMC Pulm Med 2021; 21:365. [PMID: 34772372 PMCID: PMC8590341 DOI: 10.1186/s12890-021-01694-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Accepted: 10/05/2021] [Indexed: 11/27/2022] Open
Abstract
Background Sarcoidosis-associated pulmonary hypertension (SAPH) is a prevalent and serious complication of sarcoidosis. No SAPH-specific self-report instruments for assessing SAPH symptoms and their impact on patients are available to date. This study sought to determine whether the Pulmonary Arterial Hypertension-Symptoms and Impact (PAH-SYMPACT™) questionnaire is suitable for use in patients with SAPH. Methods Patients diagnosed with SAPH participated in qualitative one-on-one telephone interviews to better understand SAPH symptoms and their impacts on patients’ lives and to determine the appropriateness of the PAH-SYMPACT™ for use in patients with SAPH. The interviews comprised concept elicitation, completion of the PAH-SYMPACT™, and cognitive debriefing. Interview transcripts were analyzed by content analysis. Results Eleven patients with SAPH were interviewed between August 2019 and June 2020. In the concept elicitation, all 11 participants endorsed shortness of breath and nine participants (82%) rated it as their “most bothersome or severe” symptom. Impacts endorsed by all 11 participants were difficulty walking uphill or up stairs and difficulty in performing daily activities. Cognitive debriefing indicated that the PAH-SYMPACT™ items were relevant and understandable to most participants and reflected their experiences of SAPH. Participants indicated that no key symptoms or impacts of SAPH were missing. They also reported that the PAH-SYMPACT™ instructions and response options were clear, and that it would be feasible to complete the 11 symptom items and one oxygen use item as part of their daily schedule. Conclusions This study suggests the PAH-SYMPACT™ is suitable for assessing symptoms and their impact in patients with SAPH. However, larger longitudinal studies are needed to confirm that it is fit for use in this patient population and that it can be used to reliably detect temporal changes in patients’ symptom status. Trial registration Not applicable. Supplementary Information The online version contains supplementary material available at 10.1186/s12890-021-01694-1.

Abstract
Sarcoidosis is a systemic heterogeneous inflammatory disease; however, the etiology and pathogenesis of sarcoidosis are still unknown. Herein, we investigated the core microRNAs and potential molecular mechanisms in sarcoidosis. The DE-miRNAs were diagnosed using the LIMMA software package. DIANA-mirPath was employed to perform pathway and GO enrichment analysis of the DE-miRNAs. PPI networks and miRNA-target gene regulatory networks were used to obtain insight into the actions of DE-miRNAs. Expression of the hub genes along with miRNAs was validated in clinical specimens. Overall, 266 DE-miRNAs were screened. Among these DE-miRNAs, hsa-miR-144, hsa-miR-126, as well as hsa-miR-106a were the upmost upregulated miRNAs; hsa-miR-151-3p, hsa-miR-320d, and hsa-miR-324-3p were the top downregulated miRNAs. NR3C1, ZBTB7A, NUFIP2, BZW1, ERGIC2, and VEGFA were mapped as the most targeted hub genes in the upregulation of miRNAs, and MCL1 and SAE1 were the most targeted hub genes in the downregulation of miRNA. VEGFA and NR3C1 were selected and potentially modulated by hsa-miR-20b, hsa-miR-126, and hsa-miR-106a. In sarcoidosis pathological tissue, hsa-miR-126 was highly expressed, and VEGFA and NR3C1 were overexpressed. In conclusion, our results revealed the dysregulation of hsa-miR-126 and a potential regulatory mechanism for pathogenesis in sarcoidosis.

Abstract
IMPORTANCE Australian- and New Zealand-based, uveitis-specialized ophthalmologists have produced recommendations for the management of juvenile idiopathic arthritis (JIA)-type chronic anterior uveitis. BACKGROUND Historically, the visual prognosis of JIA-type chronic anterior uveitis has been poor. New medical advances are likely to improve outcomes, but recently published guidelines are tailored for ophthalmic care in Europe and the United States. DESIGN This work involved a consensus survey and a panel meeting. PARTICIPANTS The Australian and New Zealand JIA-Uveitis Working Group (29 ophthalmologists) participated in the work. METHODS The Delphi technique was used to achieve consensus. MAIN OUTCOME MEASURES This work yielded consensus statements. RESULTS The Working Group achieved consensus around 18 statements related to clinical evaluation, use of topical and regional corticosteroids, use of systemic corticosteroid and non-corticosteroid immunomodulatory drugs, and management of secondary cataract and glaucoma in childhood JIA-type uveitis. CONCLUSIONS AND RELEVANCE Recommendations of the Australian and New Zealand JIA-Uveitis Working Group provide current and regionally applicable advice for managing chronic anterior uveitis in children with JIA.

Abstract
BACKGROUND Sarcoidosis is associated with a wide range of disease outcomes including spontaneous remission and progressive courses. It is necessary to identify patients with spontaneous remission without corticosteroid treatment. This study aimed to identify the markers for predicting spontaneous remission in patients with sarcoidosis. METHODS 453 patients diagnosed with sarcoidosis at the Shanghai Pulmonary Hospital between Jan 2013 and Aug 2017 and were followed-up for more than 2 years were enrolled. Patients were divided into spontaneous remission group and non-remission group. Differences of variables between groups were analyzed by chi-square test or unpaired Student's t-test. The cumulative spontaneous remission rate was analyzed using the Kaplan-Meier method. RESULTS Of the 173 patients (stage I/II/III/IV, 53/110/6/4) without medication, 117 (67.6%) achieved spontaneous remission. The serum level of soluble interleukin-2 (IL-2) receptor (sIL-2R) and the ratio of CD4/CD8 was significantly lower and CD8+ T cell was significantly higher in spontaneous remission group when compared with non-remission group (P < 0.001, P = 0.042 and P = 0.048). Multivariate logistic regression model showed sIL-2R level was an independent predictor of spontaneous remission (P = 0.021). In stage I subgroup, a cut-off value of 1129.5U/ml was obtained from the ROC curve, which yielded a sensitivity of 50% and a specificity of 94.4%. In stage II subgroup, a cut-off value of 1026.5U/ml was obtained with a sensitivity of 66.7% and a specificity of 68.7%. CONCLUSION This study provided useful information that sIL-2R level could be used as a maker for spontaneous remission in determining the treatment strategies for patients with pulmonary sarcoidosis.

Abstract
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.
