New therapies in infectious pathology
Community-acquired pneumonia (CAP) is an infectious disease with high prevalence and a high morbidity and mortality rate. Our group has been working on several lines in collaboration with various groups. Fundamentally we work in: A) Clinical indicators related to the safe management of patients with CAP. We participate as collaborators in several projects funded by the Sociedad Española de Neumología y Cirugía Torácica (Spanish Society of Pneumology and Thoracic Surgery). B) Our group maintains an open line of collaboration with several groups, mainly with the Department of Immunology at Hospital Dr. Negrín (Gran Canaria, Spain).
We collaborate on several topics, mainly mannose-binding lectin and surfactant protein, related to different aspects of host response in pneumonia. Financial support for this research has been possible through projects funded by FIS or scientific associations, in which we have participated as collaborating researchers. These two lines are active.
Our current research project addresses the incidence of cardiovascular events following CAP hospitalisation in adults, and their association with different markers of inflammation. As part of this project, we are aiming to quantify the incidence of cardiovascular disease in adult patients in the year following hospital admission due to CAP, and establish a possible relationship with mortality. In addition, we will attempt to describe the distribution of a broad spectrum of immune response mediators at hospital admission and discharge. This will allow us to characterise an inflammatory profile for these patients and determine a possible relationship with cardiovascular disease incidence.
Preliminary results are very promising: we have found a link between long-term mortality and the occurrence of cardiovascular episodes, as well as being able to select some biomarkers to improve the prediction of admission rates. We need more monitoring time to confirm the relationship between biomarkers and the development of cardiovascular episodes.
MicroRNAs (miRNAs) are a family of small, endogenous, non-coding RNAs that modulate physiological and pathological processes by post-transcriptional inhibition of gene expression. Recent studies have begun to reveal that altered expression profiles of miRNAs may be associated with the development of various lung diseases, from inflammatory diseases to lung cancer. Likewise, miRNAs are important for both adaptive and innate immunity, with regulatory effects on cell differentiation and immune function.
Recently the expression of different miRNAs in patients with cardiovascular episodes has also been published. We intend to explore the role of different miRNAs in the development of heart failure in patients with CAP and the regulation of inflammatory response in these patients.
