Introduction: The coronavirus disease 2019 (COVID-19) pandemic has led to the death of almost 7 million people, however, with a cumulative incidence of 0.76 billion, most people survive COVID-19. Several studies indicate that the acute phase of COVID-19 may be followed by persistent symptoms including fatigue, dyspnea, headache, musculoskeletal symptoms, and pulmonary functional-and radiological abnormalities. However, the impact of COVID-19 on long-term health outcomes remains to be elucidated.... Abstract
BMC pulmonary medicine, Volume 23, Issue 1, 20 3 2023, Pages 134 Diagnostic performance of eNose technology in COVID-19 patients after hospitalization. van Raaij BFM, Veltman JD, Hameete JF, Stöger JL, Geelhoed JJM
Background: Volatile organic compounds (VOCs) produced by human cells reflect metabolic and pathophysiological processes which can be detected with the use of electronic nose (eNose) technology. Analysis of exhaled breath may potentially play an important role in diagnosing COVID-19 and stratification of patients based on pulmonary function or chest CT. Methods: Breath profiles of COVID-19 patients were collected with an eNose device (SpiroNose) 3 months after discharge from the Leiden Universit... Abstract

American heart journal plus : cardiology research and practice, Volume 27, 23 4 2023, Pages 100280 Coronary calcium score in COVID-19 survivors: Association with cardiac injury and cardiac function after 6 weeks. Groen RA, de Graaf MA, Stöger JL, van Dijkman PRM, Jukema JW, Schalij MJ, Geelhoed JJM, Antoni ML
Aims: Cardiac manifestations are common in COVID-19, often elevated serum troponin levels or myocardial dysfunction on trans-thoracic echocardiography (TTE) is observed. Both parameters are associated with increased in-hospital mortality. Possibly, subclinical coronary atherosclerosis plays a role, of which severity can be assessed by calculating the coronary artery calcium (CAC) score. This study aims to determine the relation between coronary atherosclerosis and cardiac manifestations in COVID... Abstract

Background: We investigated whether COVID-19 leads to persistent impaired pulmonary function, fibrotic-like abnormalities or psychological symptoms 12 months after discharge and whether severely ill patients (ICU admission) recover differently than moderately ill patients. Methods: This single-centre cohort study followed adult COVID-19 survivors for a period of one year after discharge. Patients underwent pulmonary function tests 6 weeks, 3 months and 12 months after discharge and were psycholo... Abstract

Nakshbandi G, Moor CC, Nossent EJ, Geelhoed JJM, Baart SJ, Boerrigter BG, Aerts JGJV, Nijman SFM, Santema HY, Hellemons ME, Wijsenbeek MS
Background and objective: To develop targeted and efficient follow-up programmes for patients hospitalized with coronavirus disease 2019 (COVID-19), structured and detailed insights in recovery trajectory are required. We aimed to gain detailed insights in long-term recovery after COVID-19 infection, using an online home monitoring programme including home spirometry. Moreover, we evaluated patient experiences with the home monitoring programme. Methods: In this prospective multicentre study, we... Abstract
The international journal of cardiovascular imaging, Volume 38, Issue 9, 16 3 2022, Pages 1951-1960 Myocardial function in COVID-19 patients after hospital discharge: a descriptive study comparing the first and second 'wave' patients. Elffers TW, de Graaf MA, Regeer MV, Omara S, Schalij MJ, Groeneveld GH, Roukens AHE, Geelhoed JJM, Antoni ML
In hospitalized COVID-19 patients, myocardial injury and echocardiographic abnormalities have been described. The present study investigates cardiac function in COVID-19 patients 6 weeks post-discharge and evaluates its relation to New York Heart Association (NYHA) class. Furthermore cardiac function post-discharge between the first and second wave COVID-19 patients was compared. We evaluated 146 patients at the outpatient clinic of the Leiden University Medical Centre. NYHA class of II or highe... Abstract

Background: The major complication of COVID-19 is hypoxaemic respiratory failure from capillary leak and alveolar oedema. Experimental and early clinical data suggest that the tyrosine-kinase inhibitor imatinib reverses pulmonary capillary leak. Methods: This randomised, double-blind, placebo-controlled, clinical trial was done at 13 academic and non-academic teaching hospitals in the Netherlands. Hospitalised patients (aged ≥18 years) with COVID-19, as confirmed by an RT-PCR test for SARS-CoV-2... Abstract

Respiratory research, Volume 19, Issue 1, 29 5 2018, Pages 105 A home monitoring program including real-time wireless home spirometry in idiopathic pulmonary fibrosis: a pilot study on experiences and barriers. Moor CC, Wapenaar M, Miedema JR, Geelhoed JJM, Chandoesing PP, Wijsenbeek MS
In idiopathic pulmonary fibrosis (IPF), home monitoring experiences are limited, not yet real-time available nor implemented in daily care. We evaluated feasibility and potential barriers of a new home monitoring program with real-time wireless home spirometry in IPF. Ten patients with IPF were asked to test this home monitoring program, including daily home spirometry, for four weeks. Measurements of home and hospital spirometry showed good agreement. All patients considered real-time wireless... Abstract
