Filter by:A research team member will brush the inferior surface of the subjects' middle turbinate (nasal cavity) using a cytology brush to obtain the cells needed to perform our functional respiratory assays. An individual trained in phlebotomy will draw one 3 ml lavender top tube of blood to test c-reactive protein, calprotectin, and lactoferrin. They will also draw a 5 ml gold top serum separator tube of blood to test fibroblast growth factor-19. The participant will answer questions from the baseline survey and report their current medications interview-style with the research team member.
Community-acquired pneumonia (CAP) is a heterogeneous disease causing great morbidity, mortality and health care burden globally. Typing methods for discriminating different clinical conditions of the same disease are essential to a better management of CAP. Traditional typing systems based separately on clinical manifestations (such as PSI and CURB-65), pathogens(bacterial types, virulence, drug resistance, etc) or host immune state (immunocompetent, immunocompromised or immunodeficiency). Thus, they are barely able to represent the real disease status nor to precisely predict the mortality. As the development of multi-omic technologies, the relatedness of different phenotypes at a molecular level have revolutionized our ability to differentiate among patients. Our study is aimed at establishing a novel molecular typing method of CAP. Multi-omic (including genomics, transcriptomes, and metabolisms) data obtained from enrolled CAP patients and isolated pathogens would be integrated analyzed and interpreted. Tthe investigators believe that an appropriate molecular typing method would lead to revolutionary changes in current arrangements of CAP.
General:Prospective, randomized, double blind controlled trial of the food supplement GOLDTRAIN PLUS, to assess its safety and efficacy in comparison to placebo in subjects with upper respiratory infection. Hypothesis: The food supplement GOLDTRAIN PLUS will be superior to placebo in shortening the time to recovery from the disease symptoms. Study design and outcome measures:Study population of 182 generally healthy subjects with acute respiratory infection randomized in 1:1 ratio to active supplement versus placebo treatment, with randomization stratified by site. The study supplement administration will be continued for 7 days, and patient global assessment (PGA) will be the main primary measurement tool, based on a self-reporting questionnaire filled and monitored every 12 hours for 7 consecutive days. Throat and nasal swabs determining type of viral infection, will be taken at inclusion of patient and a number of blood tests at the end of treatment to look for any adverse effects of the medication. Analysis and conclusion: All data-from the filled questionnaires, clinical follow up and laboratory studies will be analyzed by multivariate analysis to determine the efficacy of the supplement and its correlation to the clinical and laboratory parameters.
