IntroductionChronic obstructive pulmonary disease (COPD) will soon be the third leading global cause of death and is increasing rapidly in low/middle-income countries. There is a need for local validation of the Saint George’s Respiratory Questionnaire (SGRQ), which can be used to identify those experiencing lifestyle impairment due to their breathing.MethodsThe SGRQ was professionally translated into Luganda and reviewed by our field staff and a local pulmonologist. Participants included a COPD-confirmed clinic sample and COPD-positive and negative members of the community who were enrolled in the Lung Function in Nakaseke and Kampala (LiNK) Study. SGRQs were assembled from all participants, while demographic and spirometry data were additionally collected from LiNK participants.ResultsIn total, 103 questionnaires were included in analysis: 49 with COPD from clinic, 34 community COPD-negative and 20 community COPD-positive. SGRQ score varied by group: 53.5 for clinic, 34.4 for community COPD-positive and 4.1 for community COPD-negative (p<0.001). The cross-validated c statistic for SGRQ total score predicting COPD was 0.87 (95% CI 0.75 to 1.00). SGRQ total score was associated with COPD severity (forced expiratory volume in 1 s per cent of predicted), with an r coefficient of −0.60 (−0.75, −0.39). SGRQ score was associated with dyspnoea (OR 1.05/point; 1.01, 1.09) and cough (1.07; 1.03, 1.11).ConclusionOur Luganda language SGRQ accurately distinguishes between COPD-positive and negative community members in rural Uganda. Scores were correlated with COPD severity and were associated with odds of dyspnoea and cough. We find that it can be successfully used as a respiratory questionnaire for obstructed adults in Uganda.

Abstract Background Chronic obstructive pulmonary disease (COPD) is an important risk factor for postoperative complications and mortality. To determine the effects of perioperative combination therapy, using a long-acting muscarinic antagonist (LAMA) and a long-acting β2 agonist (LABA), on preoperative lung function, postoperative morbidity and mortality, and long-term outcome in COPD patients. Methods Between January 2005 and October 2019, 130 consecutive patients with newly diagnosed COPD underwent surgery for lung cancer. We conducted a retrospective review of their medical record to evaluate that LAMA/LABA might be an optimal regimen for patients with COPD undergoing surgery for lung cancer. All patients were received perioperative rehabilitation and divided into 3 groups according to the type of perioperative inhaled therapy and management: LAMA/LABA (n = 64), LAMA (n = 23) and rehabilitation only (no bronchodilator) (n = 43). We conducted a retrospective review of their medical records. Results Patients who received preoperative LAMA/LABA therapy showed significant improvement in lung function before surgery (p < 0.001 for both forced expiratory volume in 1 s (FEV1) and percentage of predicted forced expiratory volume in 1 s (FEV1%pred). Compared with patients who received preoperative LAMA therapy, patients with LAMA/LABA therapy had significantly improved lung function (ΔFEV1, LAMA/LABA 223.1 mL vs. LAMA 130.0 mL, ΔFEV1%pred, LAMA/LABA 10.8% vs. LAMA 6.8%; both p < 0.05). Postoperative complications were lower frequent in the LAMA/LABA group than in the LAMA group (p = 0.007). In patients with moderate to severe air flow limitation (n = 61), those who received LAMA/LABA therapy had significantly longer overall survival and disease-free survival compared with the LAMA (p = 0.049, p = 0.026) and rehabilitation-only groups (p = 0.001, p < 0.001). Perioperative LAMA/LABA therapy was also associated with lower recurrence rates (vs. LAMA p = 0.006, vs. rehabilitation-only p = 0.008). Conclusions We believe this treatment combination is optimal for patients with lung cancer and COPD.

Abstract Background: Chronic obstructive pulmonary disease (COPD) is an important risk factor for postoperative complications and mortality. The utility of several perioperative bronchodilators in patients with COPD requiring surgery for lung cancer has been reported, but the most suitable agent and its specific effect on postoperative long-term prognosis remain unclear. To determine the effects of perioperative combination therapy, using a long-acting muscarinic antagonist (LAMA) and a long-acting β2 agonist (LABA), on preoperative lung function, postoperative morbidity and mortality, and long-term outcome in COPD patients.Methods: Between January 2005 and October 2019, 130 consecutive patients with newly diagnosed COPD underwent surgery for lung cancer. We conducted a retrospective review of their medical records. Patients were divided into 3 groups according to perioperative management: LAMA/LABA (n=64), LAMA (n=23) and rehabilitation only (no bronchodilator) (n=43). Results: Patients who received preoperative LAMA/LABA therapy showed significant improvement in lung function before surgery (p<0.001 for both forced expiratory volume in 1 second (FEV1) and percentage of predicted forced expiratory volume in 1 second (FEV1 %pred). Compared with patients who received preoperative LAMA therapy, patients with LAMA/LABA therapy had significantly improved lung function (ΔFEV1, 223.1 mL vs 130.0 mL, ΔFEV1 %pred, 10.8% vs 6.8%; both p<0.05). There was a trend toward a lower incidence of postoperative complications in the LAMA/LABA group compared with the LAMA and rehabilitation-only groups. In patients with moderate to severe air flow limitation (n=61), those who received LAMA/LABA therapy had significantly longer overall survival and disease-free survival compared with patients in the other groups. Perioperative LAMA/LABA therapy was also associated with lower recurrence rates. Conclusions: Patients who receive perioperative LAMA/LABA for moderate to severe COPD have improved prognosis and better pulmonary function with surgery for lung cancer. We believe this treatment combination is optimal for patients with lung cancer and COPD.

Past Half Century

During the past half-century, many studies have investigated the correlation of exercise tolerance to routine lung function in patients with obstructive pulmonary disease. In virtually all of these studies, the degree of airway obstruction was assessed in terms of forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC). Because in most studies only a weak correlation was found between exercise tolerance and degree of airway obstruction, it has been concluded that factors other than lung function impairment (eg, deconditioning and peripheral muscle dysfunction) play a predominant role in limiting exercise capacity in patients with chronic airway obstruction. Recent work, however, suggests that in patients with chronic obstructive pulmonary disease, the inspiratory capacity is a more powerful predictor of exercise tolerance than FEV1 and FVC.

Early Improvement

<p>Acute exacerbations of chronic obstructive pulmonary disease are a major cause of hospital admissions and mortality, contributing to the decline in lung function, exercise capacity and quality of life. Infections are the major cause of exacerbations and treatment includes antibiotics, bronchodilators and systemic corticosteroids as anti- inflammatory agents. This Cochrane review compared: 1. use of oral and parenteral corticosteroids with placebo use; 2. routes of administration among themselves. The results indicate that there is evidence for the use of corticosteroids in the treatment of chronic obstructive pulmonary disease exacerbations since early improvement in lung function [assessed by forced expiratory volume in one second (FEV1)] has been noted, the likelihood of treatment failure and relapse in the first month has been reduced and it shortens the hospital stay in patients who do not require intensive care regimen. However, corticosteroid therapy causes an increase in adverse effects associated with drug, namely hyperglycaemia, especially if the route of administration is parenteral. Parenteral route has not shown to be superior to oral route in treatment failure, relapse, or death. Mortality up to 30 days does not seem to be affected by the use of corticosteroids.</p><p><br /><strong>Keywords:</strong> Adrenal Cortex Hormones; Pulmonary Disease, Chronic Obstructive /drug therapy; Pulmonary Disease, Chronic Obstructive/ complications; Randomized Controlled Trials as Topic.</p>
