Predicting Risk Factors for Exacerbation of Chronic Obstructive Pulmonary Disease

Exacerbations of chronic obstructive pulmonary disease (COPD) are unfavourable events in the course of disease for most COPD patients. Published evidence indicates a significant impact of exacerbations, especially if frequent, on patients' health-related quality of life (HRQL), disease progression, mortality, health care utilisation and costs. However, the severity,evolution and outcome of an exacerbation may differ significantly between patients - some patients will recover completely in a short period of time while others may die. The identification of risk factors for an adverse outcome could help in distinguishing patients who require more intense management in order to prevent failures, achieve satisfactory recovery and reduce the negative clinical and socioeconomic impact of exacerbations.The pathogenesis of COPD is still unclear, so there is no specific treatment at present .COPD was considered to be the result of a combination of environmental and genetic factors. Genetic factors play an important role in the acute exacerbation of COPD.Therefore, it is an urgent need to explore the heterogeneity of COPD phenotype from the perspective of genes and to seek individualized prevention and treatment programs.This study is intended to provide a theoretical basis for the prevention, evaluation and development of individualized treatment plans for acute exacerbation of COPD, thereby improving the prognosis of the disease.

A40 Expiratory Flow Limitation Registry

This prospective observational multicenter registry study will include adults greater than 40 years old, diagnosed with chronic obstructive pulmonary disease, requiring home noninvasive ventilation as part of standard medical care. For the purposes of this study, chronic obstructive pulmonary disease is defined as chronic respiratory failure consisting of historical spirometry vales (FEV1 <60% predicted and FEV1/VC < 0.7) and chronic increased daytime carbon dioxide levels greater than 6.0 kPa or 45 mmHg. In addition, participants diagnosed with major organ system diseases or obstructive sleep apnea will be excluded. At least 100 men and women who consent and meet the inclusion/exclusion criteria will be asked to participate. The anticipated study duration will be 6 months. The study will involve an initial visit for the standard of care initiation of home noninvasive ventilation. At this time, potential participants will be screened for participation. If eligible once consented, medical history will be collected and baseline questionnaires related to their respiratory disease will be completed. The registry study will include 6 month of home use of the noninvasive ventilator using the BiPAP A40 EFL device. Study staff will reach out to participants on a monthly basis to review any issues, medication changes, unscheduled visits, and device data download. Additional phone calls and or visits may occur on an as needed basis if issues arise. The final visit will be an in facility visit. The primary endpoint will be the overall prevalence of Expiratory Flow Limitation (EFL) in ventilated hypercapnic COPD patients, as defined as the percentage participants exhibiting a DeltaXrs value greater than or equal to 2.8 during one or more nights of therapy.
