Vitamin D Supplementation and Clinical Outcomes in Severe COVID-19 Patients
Covid-19Respiratory Distress Syndrome1 moreSingle center, open label randomized clinical trial. Study location: tertiary hospital center (University Hospital Split, Croatia). All COVID-19 patients with positive PCR test admitted to ICU and in need for respiratory support will be eligible for inclusion in this study. Patients admitted to ICU with severe COVID-19 disease and in need for invasive or non-invasive respiratory support with low levels of vitamin D (<50 nmol/l) measured on admission. All patients are older than 18 years and have confirmed COVID-19 disease with PCR test. Intervention: All patients included in this study will receive standard of care. Patients randomized into intervention group will be receiving 10 000 IU of cholecalciferol daily. Supplement will be administered orally or via gastric tube during ICU stay or for at least 14 days in case of ICU discharge before day 14. Supplementation will begin within 48 hours of admission to ICU. Supplement will be prepared and administered by experienced nursing staff. For patients receiving supplementation, vitamin D levels will be checked on days 7 and 14. In case that vitamin D levels are > 150 nmol/l or if the calcium levels are consistently > 2.6 mmol/l, further supplementation will be stopped. Outcomes: Primary outcome is number of days spent on ventilator. Secondary outcomes: all-cause mortality on day 28, all-cause mortality on day 60, mortality at hospital discharge, clinical improvement at day 28 (WHO clinical progression scale), days spent in ICU, days spent in hospital after discharge from ICU, need for dialysis at day 28, bacterial superinfections, neutrophile to lymphocyte ratio, disease severity (CRP levels, PaO2/FiO2 ratio, D-dimer levels, fibrinogen, ferritin, PCT), adverse outcomes. Hypothesis: patients receiving Vitamin D supplementation will have shorter number of days spent on mechanical ventilation.
Ventilation and Perfusion in the Respiratory System
Respiratory FailureRespiratory Distress Syndrome4 moreRespiratory failure occurs when the lung fails to perform one or both of its roles in gas exchange; oxygenation and/or ventilation. Presentations of respiratory failure can be mild requiring supplemental oxygen via nasal cannula to more severe requiring invasive mechanical ventilation as see in acute respiratory distress syndrome (ARDS).It is important to provide supportive care through noninvasive respiratory support devices but also to minimize risk associated with those supportive devices such as ventilator induced lung injury (VILI) and/or patient self-inflicted lung injury (P-SILI). Central to risk minimization is decreasing mechanical stress and strain and optimizing transpulmonary pressure or the distending pressure across the lung, minimizing overdistention and collapse. Patient positioning impacts ventilation/perfusion and transpulmonary pressure. Electrical impedance tomography (EIT) is an emerging technology that offers a noninvasive, real-time, radiation free method to assess distribution of ventilation at the bedside. The investigators plan to obtain observational data regarding distribution of ventilation during routine standard of care in the ICU, with special emphasis on postural changes and effects of neuromuscular blockade, to provide insight into ventilation/perfusion matching, lung mechanics in respiratory failure, other pulmonary pathological processes.
Intratracheal Budesonide With Surfactant to Prevent Bronchopulmmonary Dysplasia.
Bronchopulmonary DysplasiaRespiratory Distress Syndrome in Premature Infant1 moreThis study is designed to determine whether intratracheal administration of budesonide combined with surfactant, as compared to surfactant alone, will modify ecographic (lung ultrasound score) and biological markers (IL-6 concentration in respiratory secretions) at 7 days of life in preterm infants ≤32 weeks of gestational age (GA).
Artificial Increase in Chest Wall Elastance as an Alternative to Prone Positioning in Moderate-to-severe...
Acute Respiratory Distress SyndromeDuring moderate to severe ARDS, sessions of prone positioning lead to lung and chest wall mechanics changes that modify regional ventilation, with a final redistribution of tidal volume and PEEP towards dependent lung regions: this limits ventilator-induced lung injury, increases oxygenation and convincingly improves clinical outcome. Physiological data indicate that the increase in chest wall elastance is crucial in determining the benefit by prone positioning on oxygenation. In some patients, however, prone positioning may not be feasible or safe due to particular comorbidities and/or technical issues. In the present pilot-feasibility study enrolling 15 subjects with moderate to severe ARDS in whom prone positioning is contraindicated or unfeasible, we aim at assessing whether and to what extent an artificial increase in chest wall elastance while the patient is in the supine position may yield a significant benefit to oxygenation. The increase in chest wall elastance will be achieved placing 100g/kg weight on the anterior chest wall of the patient while he/she is in the supine position: this approach previoulsy appeared safe and effective in case reports and small case series. Patient's position will be standardized (30 degrees head-up, semi seated position). This one-arm sequential study will evaluate the effects of the procedure on gas exchange, haemodynamics, lung and chest wall mechanics, alveolar recruitment (measured with the nitrogen washout-technique and multiple PV curves) and tidal volume and PEEP distribution (assessed with electrical impedance tomography).

Inhalational (Sevoflurane) Versus Intravenous (Propofol) Sedation in Adults With a Moderate Form...
Acute Respiratory Distress SyndromeThe American European Consensus Conference (AECC) 1994 defined acute respiratory distress syndrome (ARDS) as an acute inflammatory syndrome manifesting as diffuse pulmonary edema and respiratory failure that cannot be explained by, but may co-exist with, left-sided heart failure. During the sequel Conference of the European Society of Intensive Care Medicine, in 2012 minor changes were made, and since that so-called Berlin definition of ARDS is used worldwide for the description of this severe disease. Three grades of severity were proposed to distinguish ARDS according to the level of hypoxemia with a mortality of 24% in patients with mild ARDS, rising to 48% in those with severe ones. Systemic inflammation is considered to be the main reason of ARDS. Activated neutrophils interact with the alveolar-capillary membrane causing the increasing permeability with the sequence lung edema's development. Inflammatory exudate inactivates surfactant leading to collapse and consolidation of distal airspaces with progressive loss of the lung's gas exchange surface area. Unfortunately, systemic inflammatory response syndrome (SIRS) simultaneously inhibits the mechanism of active pulmonary vasoconstriction and allows deoxygenated blood to pass through unventilated areas of the lung boosting the right-to-left shunt. Both mechanisms lead to hypoxemia, which is the main and obligatory feature of ARDS. Actually, endothelial dysfunction and transcapillary leakage seem to be one of the main steps in the development of respiratory failure during ARDS. Last decades it was found out that glycocalyx is also participating in this process too. Thus, it became clear that substances preserving endothelium and glycocalyx from SIRS-causing damage may have a beneficial effect in ARDS treatment. It seems to be crucially important so as the majority of drugs failed to demonstrate any positive effects in terms of ARDS treatment. To the moment we have some evidence, which came from experimental studies, that halogenated anesthetics can preserve glycocalyx against ischemia-reperfusion injury. The primary objective for the multicentral INVERSE Trial will be to determine the effects of inhalational (sevoflurane) versus intravenous (propofol) sedation on P/F ratio on the second day, hospital mortality and ICU (intensive care unit), and in-hospital length of stay in adults with a moderate form of ARDS.
Paracetamol vs Ibuprofen for PDA Closure in Preterm Infants.
Ductus Arteriosus PatentRespiratory Distress SyndromeCurrent pharmacological options to treat an hemodynamically significant PDA (HsPDA) in preterm infants are limited to non-selective cyclo-oxygenase (COX) inhibitors, indomethacin or ibuprofen. Recently paracetamol exposure has been reported to successful closure of PDA. Aim of this randomized double-blind controlled study is to compare the efficacy and the safety of standard PDA treatment ibuprofen versus paracetamol-experimental treatment . We hypothesize that paracetamol is more effective than ibuprofen in closing PDA, perhaps ameliorating the safety profile of the pharmacological treatment.
