NCT ID: NCT06325878 Recruiting - Clinical trials for Chronic Inflammatory Demyelinating Polyradiculoneuropathy

Genetic Architecture of Chronic Inflammatory Demyelinating Polyradiculoneuropathy

GEARCIDP
Start date: November 15, 2022
Phase: N/A
Study type: Interventional

The objective of this study is to characterize the genetic architecture of a large cohort of CIDP patients to evaluate whether specific alleles/haplotypes are implicated in the risk of CIDP, in its clinical and immunological variability, severity, therapeutic response, and association with diabetes and other autoimmune diseases. We will genotype >700,000 single nucleotide polymorphisms (SNPs) by using the Illumina Global Screening Array (GSA), of approximately 1000 patients with CIDP. About 3500 healthy controls from the Italian population have been already genotyped using GWAS from our genetic department. Alleles/haplotypes will be also compared between patients with typical CIDP and its variants, between CIDP patients with and without specific antibodies, between CIDP patients with and without comorbidities, between CIDP patients with low and high levels of disability and between CIDP patients with and without response to each individual treatment (IVIg, steroids, plasma exchange)

NCT ID: NCT06325865 Recruiting - Clinical trials for Amyotrophic Lateral Sclerosis

Perception of Unpleasant Sensations During Study Procedures in ALS Patients

PESALS
Start date: April 19, 2023
Phase:
Study type: Observational

Diagnosis of Amyotrophic Lateral Sclerosis (ALS) is considered a traumatic life event for both the patient and their next-of-kin/carers, due to the lack of treatment. Clinical Trials can offer pioneering treatment to reduce the impact of the disease and improve future treatments worldwide. Research protocols may involve routine diagnostic and/or therapeutic procedures which the patients may be already aware of and, therefore, expecting specific sensations. These could compromise participation or drop-out rate. Despite everything, participation in a clinical trial can guarantee continuity of care also thanks to the execution of these same procedures, through preferential access compared to other patients. Aim of this study is to investigate the unpleasant sensations perceived by ALS patients during procedures in clinical trials. Analysing what type of pain/discomfort frightens patients during diagnostic and/or therapeutic procedures, including the different methods of administration of the study drug. Provide data to implement effective therapy and offer constant patients support throughout ALS specific and needed procedures. Evaluate if this support could influence adherence rate of ALS patients to conduct clinical trials as required. Provide information for future studies to create an ALS Clinical Trials multiple-retention-factors adherence scale. Create and implement an ALS-specific pain scale accounting for its impact on daily activities, aiding an interdisciplinary approach of pain management. Identify the best pain management strategies and compliance techniques to address ALS, not merely in clinical trials. Provide the best individualized care for ALS patients improving their quality of life and mental state. This is a descriptive phenomenological study and data will be analyzed according to Sundler's method. Based on the experience of the researchers and the recommendations proposed by Sandelowski, a total of 20 interviews are estimated in order to reach the theoretical saturation per category of reference. Data collection will be carried out through in-depth semi-structured interviews recorded (13 open-ended questions after the execution of the procedures).

NCT ID: NCT06325137 Recruiting - Nephrotic Syndrome Clinical Trials

Transcriptome Analysis in Idiopathic Nephrotic Syndrome: Steroid Responsiveness

Start date: March 16, 2023
Phase:
Study type: Observational

Idiopathic nephrotic syndrome (INS) affects the glomerular barrier by damaging the podocytes with foot process effacement, leading to a pathological increase of permeability and protein loss. INS classification is based on the clinical response to glucocorticoid (GC) therapy. When GCs treatment fails to induce remission in a four-six weeks course, patients are defined as affected with steroid-resistant nephrotic syndrome (SRNS). The whole transcriptome sequencing could consent the INS classification at onset, prior to glucocorticoids (GCs) treatment, allowing to reduction of unuseful GCs treatment. RNA sequencing technologies allow an extensive characterization of the transcriptomic profile and permit global changes in gene expression levels between different conditions such as active and remission of the disease. Of great interest is the research of a molecular biomarker to predict steroid resistance, a predictor that is not yet available. Among the candidate biomarkers, pharmacogenomic determinants are promising, even if available studies are still limited. Among these, some epigenetic factors have been previously suggested. Data obtained in animal models suggests that nucleotide-binding oligomerization domain-like receptors (NOD-like receptor) pyrin domain containing 3 (NLRP3) inflammasome can be deregulated in a wide variety of glomerular diseases, including those causing INS. Another potential marker involved in steroid response is the long noncoding RNA GAS5. Data reported in the literature indicate that abnormal levels of GAS5 in peripheral blood mononuclear cells (PBMCs) may alter steroid effectiveness in autoimmune diseases, such as inflammatory bowel disease. Preliminary findings show that the study of NLRP3 promoter methylation could be reduced in the blood of SRNS compared with steroid-sensitive nephrotic syndrome (SSNS) patients. Moreover, unpublished encouraging results on the association between Growth Arrest Specific 5 (GAS5) expression and steroid response in INS in PBMCs were obtained in a preliminary study conducted on 8 patients with the first episode of INS. PBMCs were obtained and GAS5 gene expression was evaluated using TaqMan technology. Patients affected with SRNS presented significantly higher levels of GAS5 in comparison with the SSNS group. In PBMCs from SRNS patients, the GAS5 expression could reduce the availability for binding to GCs target genes of the activated GCs receptor and suppresses GC transcriptional activity.

NCT ID: NCT06325111 Recruiting - Clinical trials for Diabetes Mellitus, Type 1

Determinants of Glycaemic Control in Children With Type 1 Diabetes

Start date: May 29, 2023
Phase:
Study type: Observational

Type 1 diabetes (T1D) is a common chronic disease of childhood associated with a significantly increased risk of micro- and macro-vascular complications, including neuropathy, nephropathy and cardiovascular diseases. The risk of development T1D comorbidities is associated with glycaemic control, a complex mechanism involving biological, physiological environmental factors. While more than 60 genetic variants were already associated with Glycated hemoglobin (HbA1c) in healthy subjects, very few genes have been identified in T1D individuals. Also, hyperglycaemia could be the cause of epigenetic changes at specific target genes, such as DNA methylation, histone modifications and microRNAs, correlated to accelerated development of diabetes-related complications. Most recently, increasing evidence also suggested that human microbiome may play a crucial role in the onset and progression of T1D and dysbiosis of the gut and oral microbiota was reported as a typical feature of hyperglycaemia. However, potential differences among poorly and good managed T1D subjects have not been still studied. Also, the exact mechanism by long-term hyperglycaemia's acts in T1D remains poorly understood. Therefore, this project will explore an emerging area of research by the study of possible genetic, epigenetic and environmental biomarkers among T1D subjects with different glycaemic control.

NCT ID: NCT06325098 Recruiting - Nephrotic Syndrome Clinical Trials

Implementation of a Diagnostic Workflow for Personalized Diagnosis of Nephrotic Syndrome

Start date: January 26, 2022
Phase: N/A
Study type: Interventional

Nephrotic syndrome (NS) is a clinical picture common to several diseases resulting from damage to podocytes and glomerular filtration barrier. Currently, there is limited consensus regarding the diagnostic pathway and management of the specific etiology. Some patients show complete response to first-line steroid therapy (steroid-sensitive nephrotic syndrome, SSNS), especially in children and young adults. The prognosis of this group is generally favorable. In contrast, patients unresponsive to steroids (steroid-resistant NS, SRNS) frequently undergo immunosuppressive therapies, which are burdened with numerous side effects. Resistance to treatment is associated with a high likelihood of progression to chronic renal disease (CKD) and kidney failure (ESKD). Recent evidence suggests that immunological mechanisms (including permeabilizing factors) are involved in the pathogenesis of post-transplant NS recurrence and SSNS. Providing patients with NS with a correct diagnosis is the cornerstone of personalized medicine, reducing morbidity and side effects of therapies, ensuring their appropriate prescription, and slowing or preventing progression to ESKD.

NCT ID: NCT06325059 Recruiting - Nephropathy Clinical Trials

The Role of Renal Progenitors and Polyploid Tubular Cell Response in Glomerular and Tubular Diseases

Start date: March 22, 2023
Phase: N/A
Study type: Interventional

Renal progenitors are a subset of parietal epithelial cells (PECs) localized at the urinary pole of Bowman's capsule. Experimental models of podocyte damage showed that PECs can potentially regenerate lost podocytes by migrating from Bowman's capsule to the glomerular tuft, acquiring the morphological and functional features of mature podocytes. Podocyte loss and damage, as well as the inability of PECs to replace lost podocytes, lead to glomerular scarring and chronic kidney disease (CKD) progression. In addition, the investigators of the present study and others have recently demonstrated the existence of a specific subpopulation of tubular cells in the human kidney with a high potential for regeneration and resistance to death, thus acting as tubular progenitors. These cells are involved in tubular response to damage during acute kidney injury (AKI) trough endoreplication (polyploidization). Kidney biopsy is the cornerstone of diagnosis in many kidney diseases leading to CKD and AKI, allowing unambiguous diagnosis in some cases and presumptive diagnosis of ongoing disease in others. Very recently, super resolution imaging techniques proved to maintain current diagnostic standards while allowing to study morphological features of pathophysiological mechanisms of glomerular and tubular diseases. The rationale of this project is to study the role of renal progenitors (PECs and tubular progenitors) in the pathogenesis of CKD and AKI trough super resolution imaging applied to human renal biopsies, to the aim of identifying relevant connections with clinical data and markers of damage and/or disease progression.

NCT ID: NCT06324578 Recruiting - Sjögren Clinical Trials

Prevalence of Pre-clinical Sjögren Disease and Other Immune Disturbances in Subjects With Autoimmune Thyroiditis Disease

Start date: September 25, 2023
Phase:
Study type: Observational

The main study hypothesis is that Sjögren Disease (SD), usually considered a disorder typical of adult females, may occur not exceptionally in adolescence or even in childhood as a subclinical process. There are several pieces of evidence in favor of this hypothesis, from the incidental detection of asymptomatic SD in pediatric age to biobank-based studies showing that biological signs of SD may precede the disease clinical onset by years or decades. The best scenario to verify this hypothesis could be that of autoimmune thyroiditis, for the following three reasons: 1) subjects with Autoimmune thyroiditis (AT) have a high risk of developing SD (7%); 2) in cases with comorbidity of SD and AT the diagnosis of AT had usually been made before; 3) subjects with AT routinely undergo periodic blood examination and neck ultrasonography (US), which may include Salivary Gland Ultrasound (SGUS) providing contributive data to detect an asymptomatic pre-SD. The knowledge of the real association between AT and pre-SD may impact on several aspects of medicine.
