Filter by:Sarcoidosis is an idiopathic disorder characterized by granulomatous inflammation involving various organ systems. The lung and mediastinal lymph nodes are the most commonly involved structures in sarcoidosis. In the presence of intrathoracic lymph nodes, transbronchial needle aspiration (TBNA) is a useful diagnostic modality, which is now guided using endobronchial ultrasound (EBUS). We hypothesize that the 19-gauge EBUS-TBNA needle will have a higher yield as compared to the conventional 22-gauge EBUS-TBNA needle in intrathoracic lymphadenopathy due to sarcoidosis. In this study, we plan to evaluate the yield and safety of the 19-gauge needle vs. the conventional 22-gauge EBUS-TBNA needle in patients with sarcoidosis.
In the last few years, high-definition (HD) videobronchoscopy has become widely available in the market and will progressively become the standard of care for airway inspection and sampling, as it provides substantially higher resolution images as compared to conventional white light bronchoscopy. Furthermore, in combination with improved video processor units, some HD videobronchoscopes offer post-processing real-time image enhancement (i-scan technology). Preliminary studies, performed in the setting of lung cancer, suggest that HD bronchoscopy with optical image enhancement (OE) may result in better detection of subtle vascular abnormalities in the airways, which are often associated with preneoplastic lesions. We hypothesize that HD videobronchoscopy could help identify bronchial involvement from sarcoidosis before it is (plainly) visible by conventional bronchoscopy.
The presence of calcifications, which is a relatively common feature in intrathoracic lymph nodes, typically contributes to confer them a heterogeneous aspect during endosonographic B-mode examination, but their prevalence and a possible association between calcifications and metastatic involvement has never been systematically evaluated. We hypothesize that, in patients undergoing mediastinal diagnosis or staging of suspected/known lung cancer/intrathoracic malignancies, the prevalence of lymph node metastases is similar in calcified and non-calcified lymph nodes.
Background: This study aimed to investigate the diagnostic value of thoracic computerized tomography (CT) which is a noninvasive method making the diagnosis of sarcoidosis. Material-Method: The data of 816 patients who received endobronchial ultrasonography (EBUS) for mediastinal lymph node sampling and were subjected to other methods were retrospectively analyzed. 192 patients (sarcoidosis: 62, non-sarcoidosis) were included in the study. The thoracic CT findings of the patients were compared in terms of mediastinal lymph node and pulmonary parenchymal involvement.
The aim of this study is to evaluate the effects of inspiratory muscle training program in inspiratory muscle endurance, breathlessness, inspiratory muscle strength, functional capacity and quality of life in patients with interstitial lung disease. Patients are evaluated before the inspiratory muscle training and after 8 weeks of training.
Sarcoidosis causes many disabling symptoms, including fatigue, muscle weakness, and exercise limitations. Physical activity programs have been shown to improve physical performance and decrease fatigue in sarcoidosis. Objectives: The aim of this study was to evaluate (1) the effect of continuous activity monitoring using an electronic activity tracker (AT), compared to controls, and (2) the effect of additional personal coaching on exercise performance and fatigue of sarcoidosis patients. Method: This prospective, randomized clinical trial included 54 sarcoidosis patients who received an AT (Group Ia: 27 with coaching and Group Ib: 27 without). Exercise capacity and fatigue scores (Fatigue Assessment Scale) were evaluated at baseline and after three months. A historical group of sarcoidosis patients (Group II; n=41) from an earlier study who did not follow a physical activity program served as controls.
Sarcoidosis is a multisystem granulomatous disease of unknown cause histologically characterized by noncaseating granulomas. Genetic factors affect disease course, which is highly variable and difficult to predict. This study aims to evaluate the predictive value of ACE and HLA genotypes on disease severity and progression in Danish patients with sarcoidosis.
Development of a Danish Sarcoidosis Registry. Characterization of a cohort of sarcoidosis patients with respect to the baseline epidemiological characteristics, comorbidities, radiology, histopathology, diagnostic investigations and treatment.
The investigators conduct a randomized, double-blind, placebo-controlled study to investigate the effects of Nelutri™on muscle strength, muscle mass, and muscle function in healthy adults for 12 weeks.
Sarcoidosis is a chronic condition which predominantly affects the lungs and lymph glands within the chest, however, may affect any organ within the body. At the present time, very little is known as to the exact cause of sarcoidosis and it is widely believed that the condition arises due to overreaction of the immune system to an unknown trigger in the environment such as an infection. Alongside this, the clinical course and progression of the condition varies considerably; some patients have a very mild form which does require any specific treatment, where as other patients develop a more severe form which can lead to permanent scarring (fibrosis) of the lungs if left untreated. At the present time it is difficult to predict how a patient will be affected by their sarcoidosis as there is a distinct lack of clinically useful markers which help predict prognosis and identify people at risk of disease progression or those who require treatment. The main aims of this study are to use a technique which captures and analyses breath samples to provide a profile of the chemicals known as volatile organic compounds (VOCs) which are present in the exhaled breath of patients with sarcoidosis. Specifically the study would look to see if these VOCs are different in patients with sarcoidosis compared to people who do not have sarcoidosis or any lung conditions. In addition, the study would look to see how these breath profiles relate to potential infections, change over time or in response to treatment with steroids. The study will involve a total of 80 patients presenting with suspected sarcoidosis and involve a total of four study visits over the course of twelve months. During each study visit a sample of breath will be collected alongside a blood test to look for markers of disease activity as well as completion of two questionnaires relating to a patients degree of breathlessness and quality of life. At the start of the study an additional questionnaire will be completed to identify possible risk factors for the development of sarcoidosis as well as the option of providing a sample of blood for genetic testing (which is voluntary). In patients undergoing a bronchoscopy or endobronchial ultrasound (EBUS), a sample of fluid which naturally lines the airways (bronchoalveolar lavage) will also be taken and used for metagenomic sequencing to try and identify any microbes which might be present within the lung and airways.
