Filter by:Tyrosine hydroxylase autoantibodies impair sympathetic innervation leading to keratitis. In this study, the investigators have shown the significant association between severity of keratitis and presence of tyrosine hydroxylase autoantibodies.
This phase I trial studies the best dose of total body irradiation when given with cladribine, cytarabine, filgrastim, and mitoxantrone (CLAG-M) or idarubicin, fludarabine, cytarabine and filgrastim (FLAG-Ida) chemotherapy reduced-intensity conditioning regimen before stem cell transplant in treating patients with acute myeloid leukemia, myelodysplastic syndrome, or chronic myelomonocytic leukemia that has come back (relapsed) or does not respond to treatment (refractory). Giving chemotherapy and total body irradiation before a donor peripheral blood stem cell transplant helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. When the healthy stem cells from a donor are infused into a patient, they may help the patient's bone marrow make more healthy cells and platelets and may help destroy any remaining cancer cells. Sometimes the transplanted cells from a donor can attack the body's normal cells called graft versus host disease. Giving cyclophosphamide, cyclosporine, and mycophenolate mofetil after the transplant may stop this from happening.
This protocol will evaluate the efficacy of Therapeutic Plasma Exchange (TPE) alone or in combination with ruxolitinib in COVID positive patients with PENN grade 2, 3, 4 cytokine release syndrome (CRS). It is hypothesized that dual intervention of acute apheretic depletion of cytokines and concomitant suppression of production will produce superior amelioration of the cytokine load and to help to prevent cytokine load rebound. This protocol is envisioned as a pilot study (n=20) for hypothesis generation for future investigation.
This study is a prospective multicenter, placebo-controlled, double-blind, randomized study to assess the effect of one dose ACI-24 versus placebo over a 74-week treatment period and 26-week safety follow-up period.
Tertiary care IBS patients will be recruited for a prospective low FODMAP intervention study, hereby focusing on the reintroduction phase of the diet, where patients are blindly challenged with different FODMAP groups administered as powder, to be added to the strict FODMAP exclusion phase. During the screening phase of two weeks, baseline data regarding psychological, nutritional, microbial, and genetics will be collected. Predictors of treatment response (a 50-point drop on the IBS-severity scoring system (IBS-SSS) during the strict FODMAP exclusion phase of 6 weeks) will be studied with linear mixed models.
The study ARITH22 will investigate the role of visuo-spatial attention on arithmetic abilities of children with 22q11.2 deletion syndrome.
This is a prospective, open-label, randomized, two-arm clinical trial conducted to evaluate the safety and efficacy of romiplostim in comparison with eltrombopag in the treatment of thrombocytopenia in patients with Wiskott-Aldrich syndrome
Although epigenetics has been identified as one of the most relevant pathophysiological components in the development of cardiovascular diseases, there is still considerable difficulty in finding markers of epigenetic damage useful in clinical practice. Moreover, these markers could be useful to predict the onset and severity of disease as well as to stratify stratification the prognostic risk during the follow-up. The aim of this project will be to evaluate the genome wide DNA methylation status in circulating CD4+ T cells and CD8+ T cells in patients with acute coronary syndromes (ACS), atrial fibrillation (AF) and with ACS in the presence of AF.
The mortality rate in SARS-CoV-2-related severe ARDS is high despite treatment with antivirals, glucocorticoids, immunoglobulins, and ventilation. Preclinical and clinical evidence indicate that MSCs migrate to the lung and respond to the pro-inflammatory lung environment by releasing anti-inflammatory factors reducing the proliferation of pro-inflammatory cytokines while modulating regulatory T cells and macrophages to promote resolution of inflammation. Therefore, MSCs may have the potential to increase survival in management of COVID-19 induced ARDS. The primary objective of this phase 3 trial is to evaluate the efficacy and safety of the addition of the mesenchymal stromal cell (MSC) remestemcel-L plus standard of care compared to placebo plus standard of care in patients with acute respiratory distress syndrome (ARDS) due to SARS-CoV-2. The secondary objective is to assess the impact of MSCs on inflammatory biomarkers.
Acute respiratory distress syndrome (ARDS) is defined using the clinical criteria of bilateral pulmonary opacities on a chest radiograph, arterial hypoxemia (partial pressure of arterial oxygen [PaO2] to fraction of inspired oxygen [FiO2] ratio ≤ 300 mmHg with positive end-expiratory pressure [PEEP] ≥ 5 cmH2O) within one week of a clinical insult or new or worsening respiratory symptoms, and the exclusion of cardiac failure as the primary cause. ARDS is a fatal condition for intensive care unit (ICU) patients with a mortality between 30 and 40%, and a frequently under-recognized challenge for clinicians. Patients with severe symptoms may retain sequelae that have recently been reported in the literature. These sequelae may include chronic respiratory failure, disabling neuro-muscular disorders, and post-traumatic stress disorder identical to that observed in soldiers returning from war. The management of a patient with ARDS requires first of all an optimization of oxygenation, which relies primarily on mechanical ventilation, whether invasive or non-invasive (for less severe patients). Since the ARDS network study published in 2000 in the New England Journal of Medicine, it has been internationally accepted that tidal volumes must be reduced in order to limit the risk of alveolar over-distension and ventilator-induced lung injury (VILI). A tidal volume of approximately 6 mL.kg-1 ideal body weight (IBW) should be applied. Routine neuromuscular blockade of the most severe patients (PaO2/FiO2 < 120 mmHg) is usually the rule, although it is increasingly being questioned. Comprehensive ventilatory management is based on the concepts of baby lung and open lung, introduced respectively by Gattinoni and Lachmann. According to these concepts, it must be considered that the lung volume available for mechanical ventilation is very small compared to the healthy lung for a given patient (baby lung) and that the reduction in tidal volume must be associated with the use of sufficient PEEP and alveolar recruitment maneuvers to keep the lung "open" and limit the formation of atelectasis. In addition to this optimization of mechanical ventilation, it is possible to reduce the impact of mechanical stress on the lung. The prone position, for example, makes it possible to free from certain visceral and mediastinal constraints, to optimize the distribution of ventilation as well as the ventilation to perfusion ratios. Thanks to the technological progress of intensive care beds, it is now possible to verticalize ventilated and sedated patients in complete safety. Verticalization could reduce the constraints imposed to the lungs, by reproducing the more physiological vertical station, and thus modifying the distribution of ventilation. Indeed, in two physiological studies published in 2006 and 2013 in Intensive Care Medicine, 30 to 40% of patients with ARDS appeared to respond to partial body verticalization at 45° and 60° (in a semi-seated or seated position). In addition to improving arterial oxygenation, verticalization appeared to decrease ventilatory stress, related to supine position, and increase alveolar recruitment, with improved lung compliance and end-expiratory lung volume (EELV) over time. Nevertheless, 90° verticalization has never been studied, nor have positions without body flexion (seated or semi-seated). In these studies, only patients with the highest lung compliance appeared to respond. These data support the current hypothesis of subgroups of patients with ARDS with different pathophysiological characteristics (morphological and phenotypic) and therapeutic responses. The investigators hypothesize that verticalization of patients with ARDS improves ventilatory mechanics by reducing the constraints imposed on the lung (transpulmonary pressure), pulmonary aeration, arterial oxygenation and ventilatory parameters. The first objective is to study the influence of the bed position of the patient with early ARDS on the variations in respiratory mechanics represented by the transpulmonary driving pressure (ΔPtp). The second objective is to evaluate changes in ventilatory physiology, tolerance and feasibility of verticalization in patients with early ARDS.
