NCT ID: NCT05072691 Recruiting - Multiple Sclerosis Clinical Trials

Prognostic Value of Cerebrospinal Fluid Immunoglobulin Free Light Chains in Patients With Multiple Sclerosis

Start date: July 14, 2020
Phase:
Study type: Observational

Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease of the central nervous system, usually presenting as clinically isolated syndrome (CIS). The course of MS following first symptoms is unpredictable, as approximately 30% of patients with MS have a benign course and don't develop significant disability while another 20-30% progress to severe disability within a relatively short time period. In this context, it is difficult to counsel an individual patient and choose the best treatment option at time of diagnosis. For these reasons, prognostic markers that could be used to predict future disease course are extremely useful. The only cerebrospinal fluid (CSF) prognostic biomarker currently used in clinical practice are oligoclonal bands (OCB) that can predict conversion from CIS to clinically definite MS, although this observation is not consistent. However, OCB analyses are qualitative with issues in reproducibility and a limited dynamic range. CSF immunoglobulin (Ig) free light chains (FLC) are a quantitative measure of humoral response in CSF that has showed greater sensitivity and specificity than OCB for confirming diagnosis of MS. Moreover, in few recent studies they seem to have also a prognostic value, predicting conversion from CIS to clinically definite MS and correlating with the Expanded Disability Status Scale (EDSS). Optic Neuritis (ON) can be a first clinical relapse of MS and is particularly interesting because it may constitute a suitable clinical model for neuroprotection studies, as visual function can be measured with quantitative methods, including Visual Evoked Potential (VEP) and Optical Coherence Tomography (OCT). The investigators aim to better explore the utility of CSF Ig FLC as potential prognostic biomarker for MS, and to predict the recovery of visual function after ON, as model of MS relapse. The investigators will study its potential correlation with MS relapses, with changes in several functional outcome scores, exploring physical disability, fatigue, behavior, cognition, upper and lower extremity function, and with MRI disease activity. For a subgroup of patient, the investigators aim to explore its potential correlation with in vivo measures of demyelination and neuronal and axonal loss after ON, as model of potential recovery after MS relapse. The investigators aim also to compare the prognostic value of Ig FLC with Neurofilament light chain (NfL), a potential prognostic biomarker wider studied in MS.

NCT ID: NCT05071911 Recruiting - Breast Cancer Clinical Trials

Targeted Axillary Dissection After Neo-adjuvant Chemotherapy

Start date: April 21, 2021
Phase:
Study type: Observational

Currently most breast cancer patients with confirmed axillary lymph node metastasis (cN1) at diagnosis are candidates for neoadjuvant chemotherapy (NAC). The increased utilization of NAC can be attributed to practical clinical advantages. The increasing use of NAC has, however, introduced questions regarding appropriate loco-regional management, including the optimal surgical approach to the axillary lymph nodes. According to current guidelines, patients presenting with cN1 disease and treated with NAC, still undergo axillary lymph node dissection (ALND). In forty percent of these patients, however, the investigators see a nodal complete pathological response (ypN0). In certain subgroups, triple negative breast cancer and Her2 amplified breast cancer, this percentage is even higher. The investigators would like to lessen surgical morbidity by performing a targeted axillary dissection. The investigators place a clip in the biopsy-proven lymph node metastasis at diagnosis. After NAC, the investigators perform a dual agent sentinel node procedure and remove the clipped node during the same surgery. When these lymph nodes are microscopically tumor-free, the investigators can abolish an ALND. Targeted axillary dissection after NAC for cN1 disease seems to have acceptable false negative rates in previous trials. The investigators would like to further define patients where an ALND can be safely omitted.

NCT ID: NCT05071781 Recruiting - Clinical trials for GI Motility Disorder

Effect of CRH on Duodenal Markers and Gastric Sensorimotor Function

Start date: May 21, 2021
Phase: Phase 4
Study type: Interventional

In the present study, during Part 1, after a baseline gastroduodenoscopy, the investigators will perform a gastroduodenoscopy twice, to take duodenal biopsies before and 2 hours after administration of CRH/placebo. The investigators will measure mucosal integrity and markers of immune activation as outlined in Parts A and B, and will use transmission electron microscopy to evaluate mast cell and eosinophil degranulation. After an interval period of at least 1 week, CRH or placebo will be administrated again in a crossover fashion. As a complementary study, the investigators will also test the effect of ex vivo mast cell blockade by lodoxamide to evaluate whether mast cells are involved in the hypothesized effect of CRH on duodenal permeability. In a second part of this study, Part 2, the investigators will perform a gastric barostat, to measure the gastric accommodation and sensitivity to distension, and a carbon-13-octanoic acid breath test to measure the gastric emptying time after administration of CRH/placebo. Healthy volunteers will have the option to choose to which part of the study (part 1 or 2) they wish to participate. They can also choose to cooperate to both study parts if preferred.

NCT ID: NCT05071495 Completed - Clinical trials for Coronary Artery Disease

TeleDiet Study: The Impact of Dietary Education and Counseling With a Smartphone Application on Secondary Prevention of Coronary Artery Disease

Start date: March 17, 2021
Phase: N/A
Study type: Interventional

Digital cardiology is gaining power in the field of preventive cardiology recently, and several trials have already shown good results of dietary therapy with digital cardiology.
