“…When we compare with BDI, VAS measures dyspnoea superficially. In a study made by Martinez et al. (2000), they used four dyspnoea scales (VAS, BDI, Borg and Numerical Rating Scale) to evaluate dyspnoea in literate and illiterate patients with COPD.…”

“…Respiratory symptoms, such as dyspnoea (duration and severity), sputum production, cough and wheezing, were assessed and used as additional confirmatory measurements regarding COPD diagnosis and assessment of disease severity. The baseline assessment was based on accepted diagnostic tools [16][17][18][19].…”

Chronic obstructive pulmonary disease (COPD) is characterised by increased oxidative stress. Dietary factors, such as ample consumption of foods rich in antioxidants, such as fruit and vegetables, might have beneficial effects in COPD patients.The association between dietary shift to foods rich in antioxidants and lung function in COPD was investigated in a 3-yr prospective study. A total of 120 COPD patients were randomised to follow either a diet based on increased consumption of fresh fruit and vegetables (intervention group (IG)) or a free diet (control group (CG)).The mean consumption of foods containing antioxidants was higher in the IG than in the CG throughout the study period (p,0.05). The relationship between consumption of foods rich in antioxidants and percentage predicted forced expiratory volume in 1 s was assessed using a general linear model for repeated measures; the two groups overall were different in time (p50.03), with the IG showing a better outcome. In investigating the effect of several confounders (sex, age, smoking status, comorbid conditions and exacerbation) of group response over time, nonsignificant interactions were found between confounders, group and time.These findings suggest that a dietary shift to higher-antioxidant food intake may be associated with improvement in lung function, and, in this respect, dietary interventions might be considered in COPD management.

“…Pulmonary function parameters, like respiratory rate, arterial blood gases and spirometric values, do not show strong correlation with breathlessness, nor can they explain all the intensity of feelings. 32 There are no animal models for evaluating breathlessness. Therefore, studies of induced dyspnea in healthy volunteers are valid tools for investigating its physiopathological mechanisms and the potential therapeutic value of new medicines.…”

CONTEXT: Dyspnea remains a therapeutic challenge, especially in chronic respiratory conditions. Recent studies have shown that the induction of unpleasant dyspnea sensations activates areas in the insular cortex. OBJECTIVE: This study was designed to investigate the potential effects of ondansetron, a potent anti-serotonin agent, on induced dyspnea sensation. TYPE OF STUDY: A randomized double blind study. SETTING: Pulmonary Function Laboratory of Hospital das Clínicas de Ribeirão Preto. PARTICIPANTS: Ten healthy male volunteers (mean age ± standard error = 23.1 ± 0.41 years) without respiratory diseases and showing normal spirometric tests. INTERVENTIONS: Uncomfortable breathing was induced in the volunteers on two different days, via the use of inspiratory resistors (loads of 0, 7, 14 and 21 cm H2O/l/sec) and breathholding, two hours after taking 8 mg of ondansetron (Ond) or placebo (Plac). MAIN MEASUREMENTS: Respiratory discomfort during breathing under loading was evaluated on a 100-mm visual analog scale. The maximum length of time of voluntary apnea was measured in seconds. RESULTS: The mean maximum voluntary apnea time did not differ between the ondansetron and placebo days (Plac = 96 ± 6.6 sec vs. Ond = 100 ± 7.9 sec). Ondansetron did not influence the dyspnea sensation induced by different inspiratory loads (0 cm H2O/l/sec: Ond = 1.4 mm ± 0.44 vs. Plac = 2.1 ± 0.85 mm; 7 cm H2O/l/sec: Ond = 16.6 ± 2.74 mm vs. Plac = 13.7 ± 2.06 mm; 14 cm H2O/l/sec; Ond = 30.5 ± 4.50 mm vs. Plac = 27.1 ± 3.44 mm; 21 cm H2O/l/sec: Ond = 50.3 ± 6.72 mm vs. Plac = 49.4 ± 6.72 mm). Ondansetron led to significant decreases in tidal volume under basal conditions and when breathing under the highest inspiratory loading (0 cm H2O/l/sec: Ond = 0.83 ± 0.26 l vs. Plac = 1.0 ± 0.28 l; 21 cm H2O/l/sec: Ond = 0.86 ± 0.23 l vs. Plac = 1.1 ± 0.22 l) CONCLUSION: The present results suggest that 5-HT3 receptors do not play an important role in the mediation of dyspnea sensations.
