Studies on the serum biomarkers of granulomatous inflammation and pulmonary interstitial disease in intrathoracic sarcoidosis have shown conflicting results. We postulated that differences in the concentrations of serum biomarkers can be explained by the heterogenous patterns of sarcoidosis seen on thoracic HRCT. Serum biomarker levels in 79 consecutive patients, newly diagnosed with intrathoracic sarcoidosis, were compared to our control group of 56 healthy blood donors.

Nevertheless, in many cases, the antigen of interest cannot be detected in paraffin section. The alternative available for good immunohistochemistry is preparation of cryosections, which usually provide decent antigen preservation and are frequently used for immunofluorescence.

Previous studies have demonstrated a relationship between biomass of fungi exposure in the home and the risk of sarcoidosis. β-glucan was present in the bronchial alveolar lavage fluid (BALF) of patients with sarcoidosis. The Kveim-Siltzbach test reagent (KSTR) induces a sarcoidosis specific, granulomatous, cutaneous response and was used to establish the diagnosis.

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.
Purpose: To investigate the prevalence of suggestive signs for ocular sarcoidosis proposed by the International Workshop on Ocular Sarcoidosis (IWOS) in patients with sarcoidosis-associated uveitis.
Methods: A retrospective study included 53 patients (77% female), with uveitis, who were seen in the period of 2010-2013 at the University Eye Hospital Ljubljana, Slovenia. All patients had confirmed pulmonary sarcoidosis based on clinical presentation, imaging and lung biopsy according to the ATS/ERS criteria.

The aim of our study was to determine the effect of diet, rich with natural antioxidants, added to physical activity (as a part of cardiac rehabilitation (CR) program) on inflammatory markers and ox-LDL, a marker of oxidative stress, closely involved in the process of chronic inflammation.
Methods: 41 male patients after AMI undergoing CR were divided into a diet group (supervised cardioprotective diet throughout the CR), and control group (CR without diet).
Introduction: The aim of the study was to compare treatment of sarcoidosis with antifungal or corticosteroid medication.
Methods: In patients with sarcoidosis antifungal medication (n = 29), corticosteroids (n = 21) or a combination (n = 27) was given. Nine patients allotted to antifungal medication were later given corticosteroids because of the lack of regression of the disease.
Background And Objectives: Sarcoidosis is an inflammatory disease with increased levels of inflammatory cytokines. Previous studies have shown a relation between the degree of granuloma infiltration and serum cytokine levels, except for interleukin- (IL-) 10. The aim of the study was to further investigate the serum levels of IL-10 in patients with sarcoidosis and relate them to fungal exposure in terms of the amount of fungi in the air of their homes and β-glucan in bronchoalveolar lavage (BAL) fluid.

Albeit not specific for sarcoidosis, it is increased in over 90% of patients with active disease. The aims of this study were to correlate CTO measurements with clinical assessment of sarcoidosis and to test CTO as a marker of sarcoidosis relapse.
View Article and Find Full Text PDFBackground And Objective: Previous studies have demonstrated increases of inflammatory mediators in sarcoidosis while epidemiological studies have also demonstrated an association with increased fungi exposure. This study measured the level of β-glucan in the lungs and of inflammatory mediators in serum, and correlated both with the extent of pulmonary granuloma infiltration.
Methods: This is a cross-sectional study of 98 patients with sarcoidosis and 26 controls.
Background: High-sensitivity C-reactive protein (hsCRP) is an important biomarker of risk for coronary heart disease morbidity and mortality. We investigated the influence of short-term cardiac rehabilitation (CR) after acute myocardial infarction (AMI) on values of hsCRP and classical risk factors, including metabolic syndrome.
Methods: hsCRP and classical risk factors were measured before and after completed 2-week CR program in 30 men after AMI.
Purpose: Oxidative stress is an important nonclassical risk factor for myocardial infarction (MI), and thus, it seems extremely important to recognize factors that effectively reduce it. The aim of our study was to explore possible influences of short-term cardiac rehabilitation (CR) of only 2 weeks in duration on oxidative stress in men after MI.
Methods: Male patients (N = 21; aged 41-88 years, median 56 years), 6 to 8 weeks after acute MI, were included in our observational study using a pretest/posttest design.
Objectives: Fungi have been suspected of contributing to the pathogenesis of sarcoidosis. A previous intervention study demonstrated an improvement in the clinical condition in 15 out of 18 patients with a long-term history of sarcoidosis when antifungal medication was added to corticosteroids. The present study was performed to compare the effects of antifungal treatment with corticosteroid treatment in sarcoidosis.

We propose to combine field imaging endoscopy with point spectral analysis for improving the overall diagnostic accuracy in clinical lung cancer detection. For this purpose, we developed an integrated endoscopy system that uses autofluorescence imaging and white light reflectance imaging to obtain high diagnostic sensitivity, while at the same time uses non-contact point reflectance/fluorescence spectroscopy to reduce false positive biopsies, thus, achieve high diagnostic specificity. A pilot clinical test on 22 lung patients demonstrated that using this system the malignant lung lesions can be differentiated from the benign lesions with both diagnostic sensitivity and specificity of better than 80%.

Study Design: Sputum and buccal cell samples were obtained from 846 patients without pulmonary disease, with nonmalignant disease, chronic obstructive pulmonary disease, asbestosis and lung cancer, stained for DNA, scanned by cytometer and scored. This was related to specificity and sensitivity for lung cancer.
Background: Sarcoidosis is a multisystemic chronic inflammatory disorder of unknown etiology with multifactorial genetic predisposition. An elevated ACE serum level is considered to be the activity marker of the disease. The involvement of the ACE I/D polymorphism in sarcoidosis susceptibility has been investigated in different populations, but results have been inconclusive.

Microbial cell wall agents, even in the absence of clinical infection, could cause a late hypersensitivity reaction leading to the formation of granulomas. A few interventions studies using antimicrobial treatment demonstrate improvement in sarcoidosis.
