Objective
We investigated the measurement properties of the incremental step test in subjects with moderate to severe asthma.
Methods
Subjects with moderate to severe persistent asthma were recruited from a tertiary university hospital specializing in treating severe asthma. All subjects performed one cardiopulmonary exercise test (CPET) and two incremental step tests (IST) in random sequences. Pulmonary gas exchange was measured during all exercise tests. The measurement properties investigated were reliability by intraclass correlation coefficient (ICC), measurement error by the standard error of measurement and minimum detectable difference, construct validity by Pearson's correlation, and interpretability by the ceiling and floor effects.
Results
Fifty subjects (38 females, mean [SD], age 43.7 [11.6] yr, % FEV1 70 [14.3], BMI 28.5 [5.3] kg/m2) completed the study. The peak oxygen uptake (peak VO2) for the CPET was 27.6 [±6.8] ml/kg/min, for the first IST was 22.3 [±5.3] ml/kg/min and for the second IST was 23.3 [±5.3] ml/kg/min. The IST presented excellent reliability (ICC=0.93, CI95% 0.88-0.96), very good measurement error (2.5%), and construct validity for peak VO2 measurement compared to the CPET (r = 0.85; p < 0.001) to assess exercise capacity in subjects with moderate to severe asthma, with appropriate ceiling (10%) and floor (0%) effects.
Conclusion
The IST presented excellent reliability and very good measurement error and validity to assess exercise capacity in subjects with moderate to severe asthma, without ceiling or floor effects.

Objective
To quantify the impact of different air pollutants on respiratory health based on robust estimates based on international data and to summarise the evidence of associations between indoor exposure to those pollutants and respiratory morbidity in the Portuguese population.
Results
Several systematic reviews and meta-analyses (MA) at the world level demonstrate the impact of indoor air quality on respiratory health, with indoor particulate matter and gasses exerting a significant effect on the airways. Volatile organic compounds (VOC) have been related to asthma and lung cancer. However, only meta-analyses on biomass use allowed documentation of long-term respiratory effects. While early publications concerning Portuguese-based populations mainly focused on indoor exposure to environmental tobacco smoke, later studies relocated the attention to relevant exposure environments, such as day care buildings, schools, residences and nursing homes. Looking at the pooled effects from the reviewed studies, high levels of carbon dioxide and particulate matter in Portuguese buildings were significantly associated with asthma and wheezing, with VOC and fungi showing a similar effect in some instances.
Conclusions
Despite the significant reduction of indoor air pollution effects after the 2008 indoor smoking prohibition in public buildings, studies show that several indoor air parameters are still significantly associated with respiratory health in Portugal. The country shares the worldwide necessity of standardisation of methods and contextual data to increase the reach of epidemiological studies on household air pollution, allowing a weighted evaluation of interventions and policies focused on reducing the associated respiratory morbidity.

Background
The carbonic anhydrase inhibitor acetazolamide stimulates ventilation through metabolic acidosis mediated by renal bicarbonate excretion. In animal models, acetazolamide attenuates acute hypoxia-induced pulmonary hypertension (PH), but its efficacy in treating patients with PH due to pulmonary vascular disease (PVD) is unknown.
Methods
28 PVD patients (15 pulmonary arterial hypertension, 13 distal chronic thromboembolic PH), 13 women, mean±SD age 61.6±15.0 years stable on PVD medications, were randomised in a double-blind crossover protocol to 5 weeks acetazolamide (250mg b.i.d) or placebo separated by a ≥2 week washout period. Primary endpoint was the change in 6-minute walk distance (6MWD) at 5 weeks. Additional endpoints included safety, tolerability, WHO functional class, quality of life, arterial blood gases, and hemodynamics (by echocardiography).
Results
Acetazolamide had no effect on 6MWD compared to placebo (treatment effect: mean change [95%CI] -18 [-40 to 4]m, p=0.102) but increased arterial blood oxygenation through hyperventilation induced by metabolic acidosis. Other measures including pulmonary hemodynamics were unchanged. No severe adverse effects occurred, side effects that occurred significantly more frequently with acetazolamide vs. placebo were change in taste (22/0%), paraesthesia (37/4%) and mild dyspnea (26/4%).
Conclusions
In patients with PVD, acetazolamide did not change 6MWD compared to placebo despite improved blood oxygenation. Some patients reported a tolerable increase in dyspnoea during acetazolamide treatment, related to hyperventilation, induced by the mild drug-induced metabolic acidosis. Our findings do not support the use of acetazolamide to improve exercise in patients with PVD at this dosing.

背景:碳酸酐酶抑制剂乙酰唑胺通过肾脏碳酸氢盐排泄介导的代谢性酸中毒刺激通气。在动物模型中,乙酰唑胺可减轻急性缺氧诱发的肺动脉高压(PH),但其对因肺血管疾病(PVD)导致的肺动脉高压患者的治疗效果尚不清楚。方法:28名PVD患者(15名肺动脉高压患者,13名远端慢性血栓栓塞性PH患者),13名女性,平均(±SD)年龄为61.6±15.0岁,稳定服用PVD药物,在双盲交叉方案中随机接受为期5周的乙酰唑胺(250毫克,b.i.d)或安慰剂治疗,中间有≥2周的冲洗期。主要终点是5周时6分钟步行距离(6MWD)的变化。其他终点包括安全性、耐受性、WHO功能分级、生活质量、动脉血气和血液动力学(通过超声心动图):与安慰剂相比,乙酰唑胺对6MWD没有影响(治疗效果:平均变化[95%CI] -18 [-40 to 4]米,P=0.102),但通过代谢性酸中毒引起的过度通气增加了动脉血氧饱和度。包括肺血液动力学在内的其他指标均无变化。与安慰剂相比,乙酰唑胺无严重不良反应,但出现频率明显高于安慰剂的副作用有味觉改变(22/0%)、麻痹(37/4%)和轻度呼吸困难(26/4%):尽管改善了血氧饱和度,但与安慰剂相比,乙酰脞胺并未改变心血管疾病患者的6MWD。一些患者表示,在乙酰唑胺治疗期间,呼吸困难的增加是可以忍受的,这与药物引起的轻度代谢性酸中毒导致的过度换气有关。我们的研究结果不支持在此剂量下使用乙酰唑胺来改善心血管疾病患者的运动状况:Gov 标识符:NCT02755298。
