ABSTRACT

Due to immunosuppression, transplant recipients are at higher risk of infections with SARS-CoV-2 and worse clinical outcomes than immunocompetent hosts. Furthermore, lung transplant patients represent a special group among solid organ recipients, since pneumonia is the main manifestation of COVID-19. However, data on the course of disease and the changes in morbidity and mortality during the course of the pandemic are limited. In our pulmonary rehabilitation clinic, we treat patients shortly after lung transplant as well as long-term transplant patients. Over the last almost 4 years of pandemic, we witnessed several COVID-19 infections in lung transplant patients in our clinic as well as patients who acquired an infection beforehand. In this paper, we aim at retrospectively describing a series of recent COVID-19 cases in our clinic, looking at the clinical course of disease and outcomes in lung transplant patients.

ABSTRACT

BACKGROUND: Coronavirus disease 2019 has become a health problem spreading worldwide with pandemic characteristics since March 2020. Post coronavirus disease 2019 symptoms are more frequent than initially expected, with fatigue as an often-mentioned issue. CASE PRESENTATIONS: We describe a 32-year-old white male and a 55-year-old white female who suffered from post coronavirus disease 2019 fatigue syndrome. On polysomnography, rapid eye movement associated sleep apnea with an increased hypopnea index during rapid eye movement phases of 36.8 and 19.5 events per hour was found. Based on the patients' burdensome fatigue symptoms, we initiated automatic positive airway pressure therapy, which diminished sleep apnea (rapid eye movement index: 0.0 in both patients) and, consequently, also the fatigue symptoms. CONCLUSIONS: Since sleep apnea and coronavirus disease 2019 are both associated with fatigue, a screening for sleep apnea might be considered in coronavirus disease 2019 patients with fatigue syndrome.

ABSTRACT

INTRODUCTION: Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are the most critical events for patients with COPD that have a negative impact on patients' quality of life, accelerate disease progression, and can result in hospital admissions and death. Although there is no distinct definition or detailed knowledge about AECOPD, it is commonly used as primary outcome in clinical studies. Furthermore, it may be difficult in clinical practice to differentiate the worsening of symptoms due to an AECOPD or to the development of heart failure. Therefore, it is of major clinical importance to investigate the underlying pathophysiology, and if possible, predictors of an AECOPD and thus to identify patients who are at high risk for developing an acute exacerbation. METHODS AND ANALYSIS: In total, 355 patients with COPD will be included prospectively to this study during a 3-week inpatient pulmonary rehabilitation programme at the Schoen Klinik Berchtesgadener Land, Schoenau am Koenigssee (Germany). All patients will be closely monitored from admission to discharge. Lung function, exercise tests, clinical parameters, quality of life, physical activity and symptoms will be recorded, and blood samples and exhaled air will be collected. If a patient develops an AECOPD, there will be additional comprehensive diagnostic assessments to differentiate between cardiac, pulmonary or cardiopulmonary causes of worsening. Follow-up measures will be performed at 6, 12 and 24 months.Exploratory data analyses methods will be used for the primary research question (screening and identification of possible factors to predict an AECOPD). Regression analyses and a generalised linear model with a binomial outcome (AECOPD) will be applied to test if predictors are significant. ETHICS AND DISSEMINATION: This study has been approved by the Ethical Committee of the Philipps University Marburg, Germany (No. 61/19). The results will be presented in conferences and published in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT04140097.

ABSTRACT

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) has become a global health problem with pandemic character. Lung transplant recipients may be particularly at risk due to the high degree of immunosuppression and the lung being the organ primarily affected by COVID-19. We describe a 16-year-old male and a 64-year-old female recently lung transplanted patients with COVID-19 during inpatient rehabilitation. Both patients were receiving triple immunosuppressive therapy and had no signs of allograft dysfunction. Both patients had close contact with a person who developed COVID-19 and were tested positive for SARS-CoV-2. Subsequently, both patients underwent systematic screening and SARS-CoV-2 was ultimately detected. Although the 16-year-old boy was completely asymptomatic, the 64-year-old woman developed only mild COVID-19. Immunosuppressive therapy was unchanged and no experimental treatment was initiated. No signs of graft involvement or dysfunction were noticed. In conclusion, our report of patients with asymptomatic SARS-CoV-2 infection and mild COVID-19, respectively, may indicate that lung transplant recipients are not per se at risk for severe COVID-19. Further observations and controlled trials are urgently needed to study SARS-CoV-2 infection in lung transplant recipients.

ABSTRACT

BACKGROUND: Numerous studies have shown the effectiveness of comprehensive pulmonary rehabilitation (PR) programs in chronic obstructive pulmonary disease (COPD). At present, it is uncertain whether PR is also effective in the management of patients with various diseases awaiting lung transplantation (LTx). METHODS: In a retrospective clinical preanalysis and postanalysis, we investigated the effects of a 5-week inpatient PR in LTx candidates. We compared data of patients with COPD, α-1-antitrypsin deficiency, interstitial lung disease, or cystic fibrosis before and after PR with regard to exercise capacity (6-min walking distance [6MWD]) and health-related quality of life (HRQL; SF36). Multivariate stepwise regression analysis was performed to detect predictors of PR outcome. RESULTS: Eight hundred eleven data sets from consecutive patients referred to our PR center before LTx could be analysed (COPD, 360; α-1-antitrypsin deficiency, 127; interstitial lung disease, 195; cystic fibrosis, 69; other, 60). After PR 6MWD increased by 56 ± 58 m (P < 0.001), the physical summary component of SF36 (0-100) improved by 1.9 ± 8.5 points (P < 0.001), the mental summary component of SF36 by 8.7 ± 13.5 points (P < 0.001). Stepwise regression analysis yielded no relevant predictors of success or nonsuccess of PR with regard to age, sex, disease, body mass index, 6MWD, and HRQL on admission. CONCLUSION: Short-term comprehensive PR can significantly improve exercise capacity and HRQL in LTx candidates to a clinically relevant extent independent of the underlying lung disease. No relevant predictor influencing PR outcome could be detected. Further research is needed to evaluate the relevance of PR before LTx and its impact on clinical outcome after transplantation.

ABSTRACT

Pulmonary rehabilitation is recommended for patients with chronic lung diseases including idiopathic pulmonary fibrosis according to international guidelines. However, data for patients with interstitial lung disease (ILD) are limited. We examined the effect of an inpatient pulmonary rehabilitation on functional status and quality of life in ILD patients. We evaluated 402 consecutive ILD patients who were admitted to a specialised pulmonary rehabilitation centre (1999-2010). All patients performed a standardised pulmonary rehabilitation programme including pulmonary function tests, blood-gas analysis, 6-min walk test (6MWT), dyspnoea rating and health-related quality of life questionnaire (the 36-item short-form health survey; SF-36) on admission and discharge. Mean duration of pulmonary rehabilitation was 30±1 days. 6MWT distance improved by 46±3 m (308±6 m versus 354±6 m; p<0.001). Dyspnoea rating did not change. Lung function testing showed marginal improvement of vital capacity (+1±0%; p = 0.002). The SF-36 questionnaire demonstrated an increase in all eight sub-scores as well as in the physical and mental health summary scores (physical 6±1 points, p<0.001; mental health 10±1 points, p<0.001). Moreover, patients with signs of pulmonary hypertension also benefited from pulmonary rehabilitation. In a large cohort of patients with ILD, pulmonary rehabilitation had a positive impact on functional status and quality of life. Considering the limited treatment options in this patient population pulmonary rehabilitation appears to be a valuable adjunct therapy.

ABSTRACT

BACKGROUND: The purpose of this study was to examine the effect of an inpatient rehabilitation program on health-related quality of life (HRQOL) and exercise capacity (EC) in long-term (>1 year after lung transplantation) survivors (LTSs) in comparison to a control group (CG). METHODS: Sixty LTSs, 4.5 ± 3.2 years after lung transplantation (LTx), were randomly assigned to two equally sized groups that were stratified for gender and underlying disease. Thirty LTSs (age 49 ± 13 years, 13 male and 17 females, 19 double LTxs, 7 BOS Stage ≥ 1) attended an inpatient rehabilitation program (intervention group, IG) for 23 ± 5 days. The CG (age 50 ± 12 years, 13 males and 17 females, 20 double LTxs, 2 BOS Stage ≥ 1) received medical standard therapy (physiotherapy). Patients were evaluated by cardiopulmonary exercise testing, 6-minute walk test (6MWT), SF-36, SGRQ and the Quality of Life Profile for Chronic Diseases questionnaire before and after (18 ± 3 days) the program. RESULTS: The groups were statistically indistinguishable in terms of clinical data. Each treatment group significantly improved their sub-maximal EC (6MWT: IG, 493 ± 90 m vs 538 ± 90 m, p < 0.001; CG, 490 ± 88 m vs 514 ± 89 m, p < 0.001) and maximal EC (VO(2peak): IG, 17.0 vs 18.5 ml/min/kg, p = 0.039; CG, 18.0 vs 19.5 ml/min/kg, p = 0.005), without reaching statistical significance between the groups. In both study groups, patients HRQOL tended to improve. Significant correlations were found between EC parameters and HRQOL scales. CONCLUSIONS: Our data suggest that structured physical training may improve exercise tolerance in LTS. Our study results did not demonstrate a significant benefit of an inpatient over an outpatient exercise program.
