NCT06800586 | RECRUITING | COPD

Tumors and Respiratory System Diseases Due to Air Pollution: New Biomarkers of Exposure and Effects
Sponsor:

IRCCS University Hospital of Bologna

Brief Summary:

This study aims to examine the exposure to atmospheric pollutants in a group of non-smoking patients suffering from lung cancer, chronic obstructive pulmonary disease (COPD), and leukemia. The exposure to atmospheric pollutants will be assessed simultaneously in a group of healthy volunteers. The ultimate goal of the study is to enhance the understanding of the mechanisms by which atmospheric pollutants act, in order to develop new tools that can help halt or at least delay the development of diseases associated with pollution.

Condition or disease

COPD

Lung Cancer (NSCLC)

Leukemia

Detailed Description:

Atmospheric pollution represents a global issue today. A significant portion of the population in Italy lives in areas where air quality standards are very low, both due to global warming and human-caused pollution. This not only poses a serious risk to human health but also has a tremendous economic and social impact on the National Health System. Atmospheric pollution is associated with a variety of diseases affecting nearly all organs and systems. In almost all currently available studies on atmospheric pollution and its effects on humans, the population's exposure to pollutants is not measured at the individual level; instead, it is estimated using various environmental sampling techniques based on geographical areas and then applied to individuals based on their residence. There is also a lack of information regarding the effects of confounding risk factors, especially concerning cigarette smoking. This study aims to acquire more information on the individual exposure to pollutants in a group of non-smoking patients suffering from lung cancer, COPD, and leukemia. The decision to evaluate only never-smokers ensures that there are no confounding factors in the association study between health and environmental pollution. During a scheduled visit at the Department of Pneumology and Respiratory Intensive Care, IRCCS AOU of Bologna, the Department of Medical Oncology, IRCCS AOU of Bologna, and the Department of Hematology, Hospital-University Company, Policlinico Riuniti di Foggia, and after obtaining informed consent, the following biological samples will be collected in a non-invasive manner and in small aliquots: exhalate, respiratory condensate, sputum, blood, and urine. The collected samples will then be analyzed by the laboratories of the Occupational Medicine Department (IRCCS - AOU of Bologna) and the Messina Institute of Technology (MeIT) of the Department of Chemical, Biological, Pharmaceutical, and Environmental Sciences (CHIBIOFARAM) of the University of Messina using advanced techniques such as electron microscopy, mass spectrometry chromatography, and for the determination of pollutants such as particulate matter and volatile compounds. Furthermore, the project also aims to identify effect biomarkers involved in the response to such agents.
