    Abstract Die pulmonale Hypertonie (PH) ist eine häufige Komorbidität von Lungenerkrankungen wie der chronisch obstruktiven Lungenerkrankung oder der idiopathischen pulmonalen Fibrose und geht mit einer erhöhten Letalität einher. Die pulmonalarterielle Hypertonie (PAH) ist hingegen eine seltene Erkrankung, ebenfalls mit hoher Letalität. Durch das häufig ältere und komorbide Patientengut der PAH ergeben sich Subgruppen, die sich hinsichtlich ihres Therapieansprechens und der Letalität von typischen PAH-Patienten unterscheiden. In den letzten Jahren hat sich gezeigt, dass sich neben dem kardialen bzw. Linksherzphänotyp auch ein pulmonaler bzw. kardiopulmonaler Phänotyp abgrenzen lässt. Die Differenzierung zu einer schwergradigen PH bei Lungengrunderkrankung kann schwierig sein und ist aufgrund der unterschiedlichen Therapiestrategien Expertenzentren vorbehalten.

    Title translation Auswirkungen einer kurzzeitigen Unterbrechung der oralen Kortikosteroidtherapie auf die Anzahl der Eosinophilen im Blut bei Patienten mit schwergradigem Asthma bronchiale.
    Abstract Background: The peripheral blood eosinophil count (BEC) is a well-established and easily accessible biomarker for asthma patients and crucial for the therapeutic decision regarding monoclonal antibody (mAB) therapy. Oral corticosteroid therapy frequently hinders the correct evaluation of BEC in patients with severe asthma, but a discontinuation of such therapy frequently comes along with severe side effects. Therefore, we examined the effect of a short 24-hour pause of OCS treatment on BEC in patients with severe asthma and followed-up whether patients with a then increased eosinophil count benefited from mAB-therapy, as expected.
    Methods: In this multicentre study we retrospectively included 24 patients with severe asthma and OCS therapy and determined their BEC count. Ten patients, where BEC count was obtained in the morning before taking medication (a de-facto 24-hour OCS pause), were assigned to group 1. Fourteen patients, where BEC was obtained after OCS tapering were assigned to group 2. Those who then received mAB treatment were followed up for treatment response (OCS dose, annual acute exacerbations, increase in forced expiratory volume in one second [FEV
    Results: We included 24 patients with a median age of 60.5 [IQR: 17.3] years. Regarding all baseline characteristics except FEV
    Conclusion: After just a short 24-hour pause of OCS therapy it was possible to demask a relevant eosinophilia in asthma patients, without risking severe side effects. In this manner, we enabled the possibility of achieving successful targeted mAB-therapy, according to the patient's individual asthma phenotype.

    Abstract Background: Interstitial lung disease (ILD) comprises a wide variety of pulmonary parenchymal disorders within which progressive fibrosing ILD (PF-ILD) constitutes a phenotypic subset. By use of speckle tracking-based strain analysis we aimed to evaluate the degree of left ventricular (LV) dysfunction in progressive vs. non-progressive fibrosing ILD (non-PF-ILD).
    Methods: A total of 99 ILD patients (mean age 63.7 ± 13.5 years, 37.4% female), composed of 50 PF-ILD and 49 non-PF-ILD patients, and 33 controls were prospectively enrolled and underwent conventional and speckle tracking echocardiography. Additional laboratory and pulmonary function testing, as well as six-minute walk test were performed.
    Results: As compared to the non-PF-ILD cohort, PF-ILD patients exhibited a significantly impaired forced vital capacity (2.4 ± 1.0l vs. 3.1 ± 0.9l, p = 0.002), diffusion capacity for carbon monoxide (DLCO, 25.6 ± 16.3% predicted vs. 43.6 ± 16.67% predicted, p <0.001) and exercise capacity response as measured by the six-minute walk test distance (268.1 ± 178.2m vs. 432.6 ± 94.2m, p <0.001). Contrary to conventional echocardiographic LV parameters, both regional and global longitudinal LV strain measurements were significantly altered in ILD patients as compared to controls. No differences in LV strain were found between both patient groups. Significant correlations were observed between global longitudinal strain, on the one hand, and systemic inflammation markers, total lung capacity (TLC) and DLCO, on the other hand (high-sensitivity C-reactive protein: Pearson´s r = -0.30, p< 0.001; interleukin-6: Pearson´s r = -0.26, p = 0.007; TLC % predicted: Pearson´s r = 0.22, p = 0.02; DLCO % predicted: Pearson´s r = 0.21, p = 0.02).
    Conclusions: ILD is accompanied by LV dysfunction. LV functionality inversely correlates with the severity of the restrictive ventilatory defect and inflammation marker levels. These observations support the assumption of persistent low-grade systemic inflammation that may link systemic cardiovascular function to ILD status.

    Abstract Background: The peripheral blood eosinophil count (BEC) is a well-established and easily accessible biomarker for asthma patients and crucial for the therapeutic decision regarding monoclonal antibody (mAB) therapy. Oral corticosteroid therapy frequently hinders the correct evaluation of BEC in patients with severe asthma, but a discontinuation of such therapy frequently comes along with severe side effects. Therefore, we examined the effect of a short 24-hour pause of OCS treatment on BEC in patients with severe asthma and followed-up whether patients with a then increased eosinophil count benefited from mAB-therapy, as expected.
    Methods: In this multicentre study we retrospectively included 24 patients with severe asthma and OCS therapy and determined their BEC count. Ten patients, where BEC count was obtained in the morning before taking medication (a de-facto 24-hour OCS pause), were assigned to group 1. Fourteen patients, where BEC was obtained after OCS tapering were assigned to group 2. Those who then received mAB treatment were followed up for treatment response (OCS dose, annual acute exacerbations, increase in forced expiratory volume in one second [FEV 1 ] and asthma control test [ACT]) after ≥3 months.
    Results: We included 24 patients with a median age of 60.5 [IQR: 17.3] years. Regarding all baseline characteristics except FEV 1 (l), both groups did not differ significantly. Among all 24 patients, after pausing OCS therapy for 2 [5.5] days the BEC increased significantly from 125.0/μl [125] to 300/μl [232.5] (p<0.001). In both individual groups BEC increased significantly as well (150 [123] to 325 [305], p=0.005 and 70 [150] to 280 [255], p<0.001), with no significant difference for increase (BEC +170/µl [205.0] vs. +195 [222.5], p=0.886). Of all 24 patients, 13 (54.2%) reached eosinophil levels ≥300/µl, while 12 of them had not exceeded this threshold before. Subsequently, 20 patients (83.3%) received mAB-therapy with 55.5% demonstrating a good treatment response within 6 [1.5] months. The response rate in patients with BEC count ≥300/µl was even higher (75.0%). There was no difference in the treatment response rate between group 1 and 2 (p=0.092).
    Conclusion: After just a short 24-hour pause of OCS therapy it was possible to demask a relevant eosinophilia in asthma patients, without risking severe side effects. In this manner, we enabled the possibility of achieving successful targeted mAB-therapy, according to the patient’s individual asthma phenotype.

    Abstract Endoscopic lung volume reduction (ELVR) is an emerging therapy option for the treatment of severe emphysema in COPD. To which extent patients profit from lung volume reduction via coils (LVRC) regarding morbidity, mortality, and quality of life is not clear yet. In this monocentric prospective cohort study, 13 COPD patients with severe emphysema (residual volume [RV] >225%) were enrolled at the University Hospital of Bonn. Activity measurements were assessed by a validated accelerometer wristband. By LVRC, RV could be reduced by 0.13 L to 5.54 ± 1.29 L. We could show a clinically relevant improvement in patients' physical activity after LVRC, measured as daily step count (497.7 ± 72.6 vs. 1,913.7 ± 182.7 steps/day, p = 0.03) and mean daily active energy expenditure (714.4 ± 73.6 vs. 2,321.3 ± 163.9 joules, p = 0.03). This improvement in physical activity is possibly associated with a positive effect on patients' morbidity and mortality.
