Abstract Objective: This study investigated the influence of Coronavirus Disease 2019 (COVID-19) on lung function in early convalescence phase. Methods: A prospective study of COVID-19 patients at the Fifth Affiliated Hospital of Sun Yat-sen University were conducted, with serial assessments including lung volumes (TLC), spirometry (FVC, FEV1), lung diffusing capacity for carbon monoxide (DLCO),respiratory muscle strength, 6-minute walking distance (6MWD) and high resolution CT being collected at 30 days after discharged. Results: 57 patients completed the serial assessments. There were 40 non-severe cases and 17 severe cases. Thirty-one patients (54.3%) had abnormal CT findings. Abnormalities were detected in the pulmonary function tests in 43 (75.4%) of the patients. Six (10.5%), 5(8.7%), 25(43.8%) 7(12.3%), and 30 (52.6%) patients had FVC, FEV1, FEV1/FVC ratio, TLC, and DLCO values less than 80% of predicted values, respectively. 28 (49.1%) and 13 (22.8%) patients had PImax and PEmax values less than 80% of the corresponding predicted values. Compared with non-severe cases, severe patients showed higher incidence of DLCO impairment (75.6%vs42.5%, p=0.019), higher lung total severity score（TSS）and R20, and significantly lower percentage of predicted TLC and 6MWD. No significant correlation between TSS and pulmonary function parameters was found during follow-up visit. Conclusion: Declining DLCO, lower respiratory muscle strength, and lung imaging abnormalities were detected in more than half of the COVID-19 patients in early convalescence phase. Compared with non-severe cases, severe patients had a higher incidence of DLCO impairment and encountered more TLC decrease and 6MWD decline.

ObjectiveIt was study the relationship between respiratory muscle strength and forced vital capacity (FVC) in patients with amyotrophic lateral sclerosis (ALS) versus healthy subjects.MethodsPulmonary function and respiratory muscle strength [maximal inspiratory (PImax), maximal expiratory (PEmax) and sniff nasal inspiratory pressure (SNIP)] were assessed in patients with ALS and healthy subjects, matched using cutoffs established in the literature for impaired pulmonary function and respiratory muscle weakness.ResultsTwenty-eight ALS patients and 28 healthy subjects were studied. We found sensitivity and specificity for PImax, PEmax and SNIP of 75/58%, 81/67% and 75/67%. The Receiver Operating Characteristic curve (ROC curve) indicated that the variables PImax, PEmax and SNIP can identify differences in respiratory muscle strength between ALS and healthy individuals at 0.89, 0.9 and 0.82, respectively. A positive correlation was recorded between FVC (%) versus SNIP, PImax and PEmax.ConclusionIn ALS, monitoring respiratory muscle strength assists in early diagnosis of respiratory dysfunction as opposed to the isolated use of FVC.

Respiratory Dead Space

The avoidance of respiratory muscle fatigue and its repercussions may play an important role in swimmers’ health and physical performance. Thus, the aim of this study was to investigate whether a six-week moderate-intensity swimming intervention with added respiratory dead space (ARDS) resulted in any differences in respiratory muscle variables and pulmonary function in recreational swimmers. A sample of 22 individuals (recreational swimmers) were divided into an experimental (E) and a control (C) group, observed for maximal oxygen uptake (VO2max). The intervention involved 50 min of front crawl swimming performed at 60% VO2max twice weekly for six weeks. Added respiratory dead space was induced via tube breathing (1000 mL) in group E during each intervention session. Respiratory muscle strength variables and pulmonary and respiratory variables were measured before and after the intervention. The training did not increase the inspiratory or expiratory muscle strength or improve spirometric parameters in any group. Only in group E, maximal tidal volume increased by 6.3% (p = 0.01). The ARDS volume of 1000 mL with the diameter of 2.5 cm applied in moderate-intensity swimming training constituted too weak a stimulus to develop respiratory muscles and lung function measured in the spirometry test.

Abstract Background Interstitial lung disease (ILD) is a serious extra-articular manifestation of rheumatoid arthritis (RA). Risk factors include smoking, the presence of rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibodies (CCP). Pulmonary function tests (PFT) show reduced carbon monoxide diffusion capacity (DLCO) early and reduced forced vital capacity (FVC) later in disease. HRCT is the gold standard diagnostic test while chest X-ray (CXR) has low sensitivity. PFT are routinely performed in the majority of RA patients at baseline at our tertiary centre. The aim of this study was to evaluate the frequency of abnormal PFT, specificity for ILD and influence on subsequent decision-making in patients newly diagnosed with RA. Methods A retrospective analysis was undertaken of patients with a new diagnosis of RA between January 2016 and December 2017. Patients meeting the ACR (2010) criteria for RA, with baseline PFT data available were included. Clinic letters and the hospital electronic records were used to obtain the data. Results 139 patients were included in the data analysis (Table 1). 23 patients had DLCO <70% predicted, while 7 patients had an FVC <80% predicted. Patients with abnormal PFT were more likely to be older, female, seropositive and to have smoked. Of the patients with DLCO <70%, CXR was abnormal in 6 patients with changes suggesting ILD in 2 patients. 13 patients had HRCT and 7/13 patients had evidence of ILD and 6/13 patients had significant emphysema on CXR or HRCT. 1 patient with DLCO of 82% had changes of ILD on a CT scan organised for another reason. Methotrexate was commenced in 19/23 patients with DLCO<70% and discontinued in 2 patients for respiratory reasons. Conclusion This evaluation suggests baseline PFT are more sensitive than baseline CXR in detecting ILD but that a DLCO <70% is not specific for this diagnosis. The abnormal PFT lead to HRCT being requested in 13/24 patients, of whom 7 had ILD which had not been identified by CXR in 5 patients. Baseline PFT are also useful as a reference point in patients who go on to develop respiratory symptoms at a later point in their illness. Disclosures A. Haque None. R. Kilding None. R. Smith None.
