Long Term Treatment

This study was designed to investigate long term treatment effects of short acting bronchodilators on respiratory symptoms, lung function, and the mean pulmonary artery pressure (mPAP) in patients with chronic obstructive pulmonary disease (COPD) and COPD combined with asthma (COPD + BA). The study involved 14 COPD patients and 16 COPD+BA patients, males and females (the average age, 60 yrs) with moderate to severe disease and the mPAP higher than 20 mm Hg. Clinical examination with scoring of cough, sputum, dyspnea, and lung auscultation signs; spirometry, ECG, echocardiography, chest X ray, and blood analysis were used. Clinical status and lung function were evaluated primarily and in 4, 12, and 24 wks; the mPAP was measured initially and in 12 and 24 wks. Before the study no one patient received persistent supporting therapy with bronchodilators, 15 COPD + BA patients and 7 COPD patients were given inhaled steroids. Persistent therapy of all the patients with Berodual 2 doses 4 times daily for 24 wks resulted in improvement in the clinical symptoms and lung function parameters, reduction in mPAP in both the groups but the results were better and they were reached faster in the patients with combined pathology. Thus, the regularly combined therapy with short acting β2 agonists and anticholinergics (Berodual) can be included in the algorithm of therapy of pulmonary hypertension in patients with COPD and COPD + BA.

Risk Patients

UNSTRUCTURED Chronic obstructive pulmonary disease (COPD) predominantly affects older adults, and claimed 3 million lives in 2016, making it the third leading cause of death worldwide. Over 35 million Americans aged 40 or older have lung function consistent with diagnosable COPD. COPD and cardiovascular disease (CVD) have a bidirectional relationship, in that one is a risk factor for developing the other. National and international consortiums recommend early screening of adults at risk of COPD, such as those with CVD. Recommended screening strategies include screening tools to assess symptoms, medical history, and handheld spirometry. Handheld spirometry has high diagnostic accuracy and if impaired lung function is indicated, these patients are referred for pulmonary function testing (PFT), the diagnostic gold standard for COPD. However, there is no clinical consensus for pulmonary screening in people with CVD. Current knowledge relating to the prevalence and incidence of CVD in people with COPD and the mechanisms that underlie their coexistence is key in combating the global burden of COPD.

Obstructive Pulmonary Disease

Lung volume reduction surgery (LVRS) improves lung function, respiratory symptoms, and exercise tolerance in selected patients with chronic obstructive pulmonary disease, who have heterogeneous emphysema. However, the reported effects of LVRS on gas exchange are variable, even when lung function is improved. To clarify how LVRS affects gas exchange in chronic obstructive pulmonary disease, 23 patients were studied before LVRS, 14 of whom were again studied afterwards. We performed measurements of lung mechanics, pulmonary hemodynamics, and ventilation-perfusion (V̇a/Q̇) inequality using the multiple inert-gas elimination technique. LVRS improved arterial Po2 (PaO2) by a mean of 6 Torr ( P = 0.04), with no significant effect on arterial Pco2 (PaCO2), but with great variability in both. Lung mechanical properties improved considerably more than did gas exchange. Post-LVRS PaO2 depended mostly on its pre-LVRS value, whereas improvement in PaO2 was explained mostly by improved V̇a/Q̇ inequality, with lesser contributions from both increased ventilation and higher mixed venous Po2. However, no index of lung mechanical properties correlated with PaO2. Conversely, post-LVRS PaCO2 bore no relationship to its pre-LVRS value, whereas changes in PaCO2 were tightly related ( r2 = 0.96) to variables, reflecting decrease in static lung hyperinflation (intrinsic positive end-expiratory pressure and residual volume/total lung capacity) and increase in airflow potential (tidal volume and maximal inspiratory pressure), but not to V̇a/Q̇ distribution changes. Individual gas exchange responses to LVRS vary greatly, but can be explained by changes in combinations of determining variables that are different for oxygen and carbon dioxide.
