COPD is an inflammatory disease characterized by enhanced chronic airway and lung inflammatory responses to noxious agents (e.g. smoke, pollutants) and progressive airflow limitation. In COPD patients there is a spillover of peripheral lung inflammation into systemic circulation resulting in increased level of various inflammatory markers such as: IL-1β, IL-6, IL-8, and TNF-α.
Diagnosis, now, is based on clinical evaluation and spirometry test and COPD treatment includes the use of LABA, LAMA and corticosteroids.
To data no plasmatic marker able to identify the stage of COPD and the response to the treatment have been documented . The aim of this study is to evaluate in COPD patients the role of microRNA as predictive biomarker, of the disease in order to have a signature of miRs typically of COPD
Chronic obstructive pulmonary disease (COPD) is a heterogeneous respiratory disorder affecting more than 200 million patients worldwide. It is characterized by enhanced chronic airway and lung inflammatory responses to noxious agents (e.g. smoke, pollutants) and progressive airflow limitation.
Both, prevalence and incidence of this disease are continuously increasing, thus the investigators can predict that in 2020 it will be the third important cause of death in the world.
Several immune system cells (e.g. macrophages, eosinophils) and biochemical mediators (e.g. tumor necrosis factor-alpha, transforming growth factor beta, Interleukins and metalloproteases) are involved in its development and in symptom severity.
It has been suggested that in COPD patients there is a spillover of peripheral lung inflammation into systemic circulation resulting in increased level of various inflammatory markers such as: IL-1β, IL-6, IL-8, and TNF-α. Those biomolecules are responsible of various complication associated with COPD such as cardiovascular disease, hypertension and skeletal muscle weakness to name a few. It is worth to note that the increase of systemic inflammatory markers is also responsible of diabetes, obesity and metabolic syndrome development in COPD patients.
Diagnosis, now, is based on clinical evaluation and spirometry test and COPD treatment includes the use of LABA, LAMA and corticosteroids. Therefore, an early diagnosis in order to asses a specific treatment it is mandatory.
Sarioglu et al.,reported that systemic inflammatory markers levels (in plasma) TNFα, IL-6 and C-reactive protein, persist in the stable period in 110 COPD patients and the C-reactive protein levels correlate with the COPD Assessment Test.
However, C-reactive protein is not a specific marker, while to date more appropriate marker(s) could be represented by microRNA (miR) a key class of gene expression regulators, emerging as crucial players in various biological processes such as cellular proliferation and differentiation, development and apoptosis.
In this concern, Stolzenburg et al., documented, in an experimental model of COPD, that miR-1343 reduces the expression of both isoform of TGF-b receptor 1 and 2, directly targeting their 3' UTRs mRNA region, suggesting a role in the improvement of lung fibrosis.
To date, no other data have been performed yet on this topic. In the present project the investigators would like to screen with nCounter GX Human Inflammation Kit a comprehensive number of 249 human genes known to be differentially expressed in inflammation. The gene list represents a broad range of inflammation-related pathways. In parallel miRs screening will be performed (800 in a single reaction tube) using NanoString Technology Platform. This technology is robust and sensitive and today is used for the validation of New Generation Sequence (NGS) data. Our aim is to evaluate in COPD patients the role of miRs as predictive biomarker, of the disease in order to have a signature of miRs typically of COPD. The signature could be used to monitoring the therapeutic application of drugs used in COPD as well as to asses a Prediction COPD Diagnostic test.
The absence of a plasmatic marker able to identify the stage of disease and the response to the treatment leads to COPD exacerbation and progression, this represent, in the real life, a common problem during COPD treatment and is also related with an increase of sanitary health costs. Last year, the European health bill for COPD treatment increased by USD 10 million and the market is thought to increase up to USD 37.7 million by 2030.
University of Catanzaro is the lead sponsor of 43 studies on the registry; 2 are open to participants now.
Counted across the registry records on this site, refreshed daily.
An open label, parallel groups study, will be performed after it is approve by the Ethical committee and before the beginning of the study, all participants will be informed about the aim, procedures, risks and benefits of the study and they will provide a written informed consent
