Filter by:This project focuses on the sub-group population with pulmonary sarcoidosis - a condition that causes red swollen tissue called granulomas to develop in organs such as the lungs. The condition is associated to symptoms of shortness of breath and a persistent dry cough. The aim of the research is to investigate the role of physical activity, exercise and diet within pulmonary sarcoidosis-related outcomes. Exercise has the potential to improve symptoms of pulmonary sarcoidosis including fatigue, dyspnoea, quality of life (QOL) and exercise tolerance. The use of exercise in symptomatic patients is supported by current evidence but is limited and requires further understanding, given the unique nature of the condition, in terms of physical and psychological outcomes. Specific dietary and exercise recommendations are limited by the lack of evidence for specific modifications such as the type(s), intensities, frequency and duration. The study will involve completion of validated questionnaires including quality of life (QOL; Sarcoidosis Health Questionnaire (SHQ) (see appendix III), the SHQ comprises of 29-item, 7 point Likert scale questionnaire and fatigue (Fatigue Assessment Scale; FAS (see appendix IV) and will require participants to attend two visits to the Kingston University, Human Performance Lab at Penrhyn Rd campus, this is to ensure reliability and validity for the data collected. The visits will consist of a range of physical tests including lung function, a six-minute walk test and muscle strength tests. The primary aim of the study is to ascertain the physical activity patterns in those with pulmonary sarcoidosis with regards to perceived physical activity, measured using the the International Physical Activity Questionnaires (IPAQ) (appendix V), which comprises of 27 items across five activity domains and actual physical activity ,measured by tri-axial accelerometry, fatigue assessment scale (appendix IV). The secondary aim of the study is to understand the effect of pulmonary sarcoidosis in relation to muscle strength and exercise capacity against physical activity, lung function and oxygen saturation and how these differ from healthy normative values. Participants will be asked to read the participant information and declare consent before starting the study. Only the researcher and supervisors of the study will have access to the raw data. Anonymity will be kept all times.
This is a multicenter, single-arm, unblinded/open-label study of the effect size of HRCT endpoints in response to glucocorticoid induction therapy in subjects with a diagnosis of pulmonary sarcoidosis who have not received glucocorticoid as initial sarcoidosis therapy (≥ 20 mg/day prednisone or prednisolone) or other sarcoidosis therapy for at least 3 months prior to enrollment. This study will enroll a total of approximately 24 subjects.
The purpose of this study is to find out if Acthar Gel is safe and effective to treat pulmonary sarcoidosis. Participants will be randomly assigned (like flipping a coin) to receive a shot under their skin of Acthar Gel or a matching placebo gel that has no drug in it. They will receive their assigned shot twice a week for 24 weeks. All participants who complete the 24-week treatment period will be eligible to receive Acthar Gel for 24 more weeks, even if they were originally in the placebo group.
The purpose of this study is to validate the method of analysing Positron Emission Tomography (PET) images to assess lung inflammation. Development of novel therapeutic drugs requires a biomarker which is sensitive to the underlying disease and can respond to therapeutic interventions. PET is a potential imaging biomarker which can target molecular and cellular processes. There is currently no standardised method of analysing PET lung data and a lack of validation for the existing techniques. This study is divided in to two parts. Part A aims to determine the best method to perform 18F-FDG PET/CT lung analysis and how it correlates with cell counts from bronchoalveolar lavage (BAL) samples taken from participants with active pulmonary sarcoidosis. Part B will compare imaging data from healthy volunteers who have either undergone a Lipopolysaccharide (LPS) challenge (whereby the lung is temporarily inflamed) or saline equivalent to determine whether lung inflammation can be detected by 18F-FDG PET/CT. No medications will be given and patients will not be asked to stop or change existing medication.
For pulmonary sarcoidosis, the initial dose recommended by the joint statement of the American Thoracic Society (ATS), European Respiratory Society (ERS), and The World Association of Sarcoidosis and Other Granulomatous Disorders (WASOG) is 20-40 mg per day.5 The exact dose and duration of treatment for sarcoidosis are unknown.4 We hypothesize that a higher dose of 40 mg per day as compared to a 20 mg/day dose of prednisone will be more effective in preventing post-treatment relapse by effective initial suppression of the granulomatous inflammation and reduction of the disease load. In this study, we compare the efficacy and safety of medium dose (40 mg/day prednisone) and low dose (20 mg/day prednisone) glucocorticoids in the treatment of acute sarcoidosis.

Sarcoidosis is a multi-system granulomatous disorder that is triggered and influenced by gene-environment interactions. Although sarcoidosis predominantly affects the lungs in most cases, the clinical disease course is highly variable and any organ can be affected leading to end organ damage despite currently available therapeutics that unfortunately also have numerous and potentially devastating side effects. The environmental triggers of sarcoidosis are unknown but several occupational, environmental and infectious agents have been associated with sarcoidosis in susceptible hosts. Exposure to these triggers result in inflammation, characterized by activation of CD4+ T-cells, cytokine production, subsequent recruitment of other immune cells, and granuloma formation. Although several genetic markers have been associated with sarcoidosis, none fully explain individual susceptibility or clinical course variability, strongly implicating the environment and epigenetics. We have the ability to generate a map of the epigenetic histone modifications in immune cells via Chromatin Immuno-Precipitation coupled with next generation sequencing (ChIP-seq) and a map of transcriptome profiles via RNA-seq. The availability of histone and transcriptional signatures defining T cell activity in sarcoidosis will help identify the specific molecular programs affected by disease processes and can become the basis for future discovery of novel biomarker diagnostics in a clinical setting.
The goal of this study is to evaluate the diagnostic agreement between, on the one hand, ultra-low dose CT and MRI with UTE pulse sequences, and on the other hand, standard CT scan, to quantify lung parenchyma patterns in thoracic sarcoidosis.
