BACKGROUND: Clinically hypomyopathic dermatomyositis is a rare disease that is important to recognize, investigate and treat early as it is associated with poor prognosis. In a proportion of patients, myositis specific antibodies could be negative, but with high clinical suspicion, myositis associated antibodies should be ordered. Anti-MDA-5 antibodies was reported in literature to be associated with severe and rapidly progressive interstitial lung disease, with few case reports of pneumothorax and/or pneumomediastinum...

The overlap between asthma and chronic obstructive pulmonary disease (COPD) has attracted the interest of pulmonary physicians; thus, measurement of carbon monoxide diffusion capacity (DLco) and/or transfer coefficients (Kco, DLco/VA) may become valuable in clinical settings. How these parameters behave in chronic obstructive lung diseases is poorly understood. We predicted that Kco might more accurately reflect emphysematous changes in the lungs, than DLco. We examined DLco and Kco in non-smokers and smokers with asthma and investigated their relationships with forced expiratory volume in 1 s (%FEV1 ) by group...

Despite the importance of preoperative risk-stratification, there is a lack of consensus on how to identify high-risk patients for pulmonary resection. Enrollment criteria for national trials propose one definition based on preoperative pulmonary function tests. We sought to examine the value of preoperative forced expiratory volume in 1 second (FEV1) and diffusion capacity for carbon monoxide (DLCO) to predict short-term outcomes following pulmonary resection. Using our institutional Society of Thoracic Surgeons (STS) database we identified 419 consecutive lung cancer patients who presented to our institution for pulmonary resection between 2012 and 2016...

Dyspnea as a subjective feeling of lack of air is the patients with the pathology of the respiratory system. Objectivization of this phenomenon is difficult, despite the introduction of questionnaires about the degree of dyspnoea. The results of these assessments do not always correlate with the results of spirometric tests. In patients with asthma, dyspnoea is caused by airway obstruction. In the case of patients with lung sarcoidosis, the complexity of the phenomenon causes that many mechanisms and factors are responsible for the dyspnea symptoms in these patients...

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...

Alveolar-capillary membrane evaluated by carbon monoxide diffusion (DLCO) plays an important role in heart failure (HF). Surfactant Proteins (SPs) have also been suggested as a worthwhile marker. In HF, Levosimendan improves pulmonary hemodynamics and reduces lung fluids but associated SPs and DLCO changes are unknown. Sixty-five advanced HF patients underwent spirometry, cardiopulmonary exercise test (CPET) and SPs determination before and after Levosimendan. Levosimendan caused natriuretic peptide-B (BNP) reduction, peakVO2 increase and VE/VCO2 slope reduction...

In Europe and America, the newly-developed, simultaneous measurement of diffusing capacity for CO (DLCO ) and NO (DLNO ) has replaced the classic DLCO measurement for detecting the pathophysiological abnormalities in the acinar regions. However, simultaneous measurement of DLCO and DLNO is currently not used by Japanese physicians. To encourage the use of DLNO in Japan, the authors reviewed aspects of simultaneously-estimated DLCO and DLNO from previously published manuscripts. The simultaneous DLCO -DLNO technique identifies the alveolocapillary membrane-related diffusing capacity (membrane component, DM ) and the blood volume in pulmonary microcirculation (VC ); VC is the principal factor constituting the blood component of diffusing capacity (DB ,DB =θ·VC where θ is the specific gas conductance for CO or NO in the blood)...

The value of rates of change in FEV1 and DLCO to predict disease progression, and initiation of mTOR inhibitor therapy has not been evaluated.In 84 pre-menopausal LAM patients, individual rates of change in FEV1 and DLCO and 95% confidence intervals (CI), were used to derive subsequent lowest values of FEV1 and DLCO that would prompt initiation of sirolimus therapy. These treatment criteria were compared with one based on FEV1 or DLCO ≤70% predicted. In 12 patients undergoing sirolimus therapy both methods for determining the optimal point for initiation of therapy were evaluated...

Lung function reference values are traditionally based on anthropometric factors, such as weight, height, sex, and age. FVC and FEV1 decline with age, while volumes and capacities, such as RV and FRC, increase. TLC, VC, RV, FVC and FEV1 are affected by height, since they are proportional to body size. This means that a tall individual will experience greater decrease in lung volumes as they get older. Some variables, such as FRC and ERV, decline exponentially with an increase in weight, to the extent that tidal volume in morbidly obese patients can be close to that of RV...
