BAL is a valuable method in diagnostic pathway of pulmonary sarcoidosis. However, results of BALF examination must be interpreted considering a specific clinical case. BALF CD4/CD8 ratio depends on clinical and radiographic manifestation.
Background: The aim of the present study was to identify specious radiologic and/or physiologic prognostic marker(s), which lead to optimize of the patient follow-up frequency. Methods: Eighty consecutive patients with newly diagnosed pulmonary sarcoidosis. Patients underwent chest radiography, high-resolution computed tomography (HRCT) examination, pulmonary function tests (PFT), bronchoscopy with bronchoalveolar lavage (BAL) and lung biopsy, and bronchoalveolar lavage fluid (BALF) cell examination. Results: The reduction in PFT values seen in radiological sarcoidosis stage III was greater than that seen in stages I and II. The percentage of neutrophils in the lungs was found to increase in stages II and III. PFT indices were correlated negatively with the consolidation and ground glass opacities CT scores, but not with the micronodule or macronodule scores. The rise in the percentage of BALF lymphocytes was associated with the restriction pattern of PFT. The diagnostic value of BALF for sarcoidosis was higher when the typical radiologic patterns of stage I disease were found and that smoking decreased the diagnostic value of CD4/CD8 ratio. Conclusions: This study supports the opinion that the staging of the pulmonary sarcoidosis with chest X-rays is still valuable from the prognostic point of view, because significant correlations between the radiologic stages of sarcoidosis and PFT parameters were found. Chest HRCT was significantly superior to chest X-ray in detecting mediastinal and pulmonary parenchymal changes. However, the prognostic role of HRCT needs to be better investigated evaluating serial examinations. Only consolidation and ground glass scores (neither of which are frequently found in sarcoidosis) hold prognostic value, since these were negatively correlated with PFT parameters.
Abstract. Of highest biological value are natural concentrates of optimally combined substances produced by nature. One of food supplements of this kind is dietary Spirulina produced by the Tianshi firm (China). It is a most rationally balanced food supplement of a high biological value; it satisfies the needs of the whole body, including its immune system. The aim of the current work was to assess the effect of the multicomponent natural food supplement Spirulina on the physical development, blood morphological, biochemical picture and immune function of sportsmen. Materials and Methods: The study cohort comprised 12 high performance sportsmen (age 20-22 years). They were using tablets of Spirulina, a dietary product for 14 days. Physical development was determined with the aid of standard methods. The general blood picture was analyzed with the aid of a Micros-60 hematological analyzer (company ABX DIAGNOSTICS, France). Lymphocytes and their subsets were analysed by flow cytometery
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
