the st george respiratory questionnaire

Mehrdad Behnia, Courtney M Wheatley, Alberto Avolio, Bruce D Johnson
BACKGROUND: During exercise as pulmonary blood flow rises, pulmonary capillary blood volume increases and gas exchange surface area expands through distention and recruitment. We have previously demonstrated that pulmonary capillary recruitment is limited in COPD patients with poorer exercise tolerance. Hypoxia and endothelial dysfunction lead to pulmonary vascular dysregulation possibly in part related to nitric oxide related pathways. PURPOSE: To determine if increasing dietary nitrate might influence lung surface area for gas exchange and subsequently impact exercise performance...

Study Objectives: Sleep quality is poor among patients with COPD, and studies show sleep disturbance is associated with low overall quality of life in this population. We evaluated the impact of patient-reported sleep quality and sleep apnea risk on disease-specific and overall quality of life within COPD patients enrolled in the SPIROMICS study, after accounting for demographics and COPD disease severity. Methods: Baseline data from 1,341 participants [892 mild/moderate COPD (FEV1≥50% predicted); 449 severe COPD (FEV1<50%)], were used to perform three nested (blocks) regression models to predict quality of life (Short Form-12 mental and physical components and St...

The aim of this study was to assess health-related quality of life (HRQL) in patients with chronic obstructive pulmonary disease (COPD) and to discuss the different tools available for its assessment. The most widely used assessments are the St. George respiratory questionnaire (SGRQ) and the COPD assessment test (CAT) questionnaire. Both have a different difficulty in exam completion, calculation, and scoring. No studies exist that analyze the validity and internal consistency of using both questionnaires on patients admitted to the hospital for a COPD exacerbation...

Background: Osteoporosis is a well-known comorbidity in COPD. It is associated with poor health status and prognosis. Although the exact pathomechanisms are unclear, osteoporosis is suggested to be either a comorbidity due to shared risk factors with COPD or a systematic effect of COPD with a cause-effect relationship. This study aimed to evaluate whether progression of osteoporosis is synchronized with that of COPD. Materials and methods: Data from 103 patients with COPD included in the Hokkaido COPD cohort study were analyzed...

Pulmonary function tests (PFTs) traditionally used in clinical practice do not accurately predict exercise intolerance in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to assess whether the nitrogen single-breath washout (N2SBW) test explains exercise intolerance and poor quality of life in stable COPD patients. This cross-sectional study included 31 patients with COPD subjected to PFTs (including the N2SBW test) and a cardiopulmonary exercise test (CPET). Patients were also evaluated using the following questionnaires: the COPD assessment test (CAT), the 36-Item Short Form Health Survey (SF36) and St...

PURPOSE: Pulmonary rehabilitation (PR) improves exercise tolerance in patients with chronic obstructive pulmonary disease. However, it is unclear why some patients do not improve quality of life during a training program. Our objective was to evaluate the differences between patients with chronic obstructive pulmonary disease who improve and those who do not improve quality of life during a pulmonary rehabilitation program. METHODS: Seventy-three patients underwent a PR program...

Antibiotics have previously demonstrated anti-inflammatory properties, and they have been linked to therapeutic benefit in several pulmonary conditions that feature inflammation. Previous research suggests that these anti-inflammatory properties may be beneficial in the treatment of COPD. This review assesses the potential benefit of prophylactic, long-term, and low-dose antibiotic therapy in COPD, and whether any effects seen are anti-inflammatory in nature. Randomized, controlled trials comparing antibiotic therapy with placebo in subjects with stable COPD were evaluated...

Background: Symptom severity is the largest factor in determining subjective health in COPD. Symptoms (eg, chronic cough, dyspnea) are associated with decreased health-related quality of life (HRQoL). We evaluated the impact of arformoterol on HRQoL in COPD patients, measured by St George's Respiratory Questionnaire (SGRQ). Post hoc growth mixture model (GMM) analysis examined symptom response profiles. Methods: We examined data from a randomized, double-blind, parallel-group, 12-month safety trial of twice-daily nebulized arformoterol 15 µg (n=420) versus placebo (n=421)...
