There are about 13446 clinical studies being (or have been) conducted in Belgium. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Although for many years the Brugada syndrome has been labelled as a purely electrical disease in the structurally normal heart, the evolution of imaging techniques has enabled the discovery of subtle morphofunctional alterations in some of the Brugada syndrome patients. We will use new echocardiographic techniques to assess cardiac function in these patients and new parameters will be evaluated for their prognostic value as risk stratificators.
Pragmatic trial to define the magnitude and the predictive factors of the response to omalizumab and mepolizumab in adult patients with severe refractory asthma and eligible to both therapies.
The purpose of the Phase 2 CSEG101B2201 study is to confirm and to establish appropriate dosing and to evaluate the safety in pediatric participants ages 6 months to <18 years with a history of VOC with or without HU/HC, receiving crizanlizumab for 2 years. The efficacy and safety of crizanlizumab was already demonstrated in adults with sickle cell disease. The approach is to extrapolate from the PK/pharmacodynamics (PD) already established in the adult population. The study is designed as a Phase II, multicenter, open-label study.
In this observational study, the investigators aim to evaluate whether changes in the retinal and choroidal circulation, as assessed by Optical Coherence Tomography (OCT) and the quantification of retinal amyloid deposits using auto-fluorescence and hyperspectral retinal imaging, are correlated with the degree and subtype of dementia and with the presence or absence of a positive amyloid scan. For this purpose, patients with established Alzheimer's Disease (AD) and Lewy Body Dementia (LBD), as well as amyloid positive and amyloid negative Mild Cognitive Impairment (MCI) and aged matched cognitively intact patients will be included in this cross-sectional study.
In this study the topical use of cream with live probiotic bacteria was evaluated for its efficacy in reducing acne symptoms and its effect on the skin microbiota on patients with acne. Patients with mild to moderate acne used the probiotic cream for 8 weeks and clinical evaluation and sampling was done at start, 4, 8 and 10 weeks. Next-Generation Sequencing was used to analyze the skin microbiota of the patients.
This is an extension study to evaluate safety and efficacy of ozanimod in participants with moderately to severely active Crohn's Disease.
Because of a shared ontogenic origin, the retina displays similarities to the brain and spinal cord in terms of anatomy, functionality, response to insult, and immunology. Hence, the retina can be approached as an integral part of the central nervous system. The occurence of ocular manifestations in several neurodegenerative pathologies, such as Alzheimer's disease and Parkinson's disease, accentuates the strong relationship between eye and brain. Particularly retinal changes can present a substrate for cerebral changes in these disorders. Offering a 'window to the brain', the transparent eye enables non-invasive imaging of these changes in retinal structure and vasculature. In this project, the potential of retinal biomarkers for e.g. Alzheimer's will be explored with the aim to overcome some of the hurdles in the current management of these pathologies, mainly the lack of techniques for patient screening and early diagnosis. The aim of this clinical trial is to correlate the retinal biomarkers for Alzheimer's with neuro-imaging, and cognitive function. Integrating the results will yield non-invasive retinal biomarkers for clinical research, screening, and follow-up of disease progression in various neurodegenerative disorders.
This is a study to demonstrate the effect of oral ozanimod as maintenance therapy in participants with moderately to severely active Crohn's Disease.
When patients suffer from chronic pain after multiple back surgeries, this is denominated as the 'failed back surgery syndrome'. A possible treatment for these patients is spinal cord stimulation. This is an invasive treatment where no other treatment options (medication, minimal invasive treaments) can offer progress to the patients' health status. In spinal cord stimulation, an electrode will be placed at the spinal cord under local anaesthesia whereas via a battery a painless electrical stimulation will arise. Clinical research have demonstrated that a new way of spinal cord stimulation can improve back and leg pain significantly. This will lead to a better quality of life for the patients and a decreased use of medications. In Ziekenhuis Oost-Limburg, different manners of spinal cord stimulation will be compared to each other.
Crohn's disease (CD), a chronic inflammatory process in intestinal segments leads to tissue damage. More than two thirds of CD patients need intestinal resection. Symptomatic clinical recurrence occurs in 60% by 10 years. The principal factors affecting postoperative recurrence are active smoking, penetrating disease, perianal lesions history, prior intestinal resection, small bowel resection extent, and prophylaxis treatment absence. Ileocolonoscopy within one year of surgery can predict clinical recurrence risk. Different therapies are proposed after surgery, to prevent post-operative recurrence : Thiopurines, 6-mercaptopurine (positive for clinical and endoscopic postoperative recurrence prevention), Anti-tumour necrosis factor therapy (anti-TNF), the most effective therapy. Intestinal microbiota acts as a central factor in the CD pathogenesis, and fecal stream role is clearly shown. Various changes in luminal flora with a possible link to local inflammation was also demonstrated. Bacteria associated with postoperative recurrence could be more pathogenic as adherent invasive E coli (AIEC), which could be a pathogen in CD through several mechanisms including increased mucosal colonization, adherence, replication and induction of TNF secretion. Alternatively, postoperative CD recurrence could be linked to a protective commensal species lack, such as Faecalibacterium prausnitzii. Microscopic inflammation occurs as early as 8 days after anastomosis in the neoterminal ileum mucosa. IL6, IL10 and TGFb levels, measured in neoterminal ileum early after surgery are associated with different rates of postoperative recurrence. It suggests cytokines implication in postoperative recurrence. T cells are major players in the intestinal immune response. The presence at time of surgery and persistence of disease inducing T cell clonal expansions could play an important role in post-operative recurrence. The main objective is to define a classification of ileal Crohn's Disease based on data integration on a large cohort of patients.
