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 Moreover, unpublished encouraging results on the association between Growth Arrest Specific 5 (GAS5) expression and steroid response in INS in PBMCs were obtained in a preliminary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: 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: NCT06185257 Not yet recruiting - Clinical trials for Chronic Renal Disease and Nephrotic Syndrome

Electroencephalographic Changes in Nonconvulsive Children With Chronic Renal Disease

Start date: February 15, 2024
Phase:
Study type: Observational

Chronic kidney disease (CKD) arises from many heterogeneous disease pathways that alter the function and structure of the kidney irreversibly, over months or years. The diagnosis of CKD rests on establishing a chronic reduction in kidney function and structural kidney damage. The best available indicator of overall kidney function is glomerular filtration rate (GFR), which equals the total amount of fluid filtered through all of the functioning nephrons per unit of time The definition and classification of CKD have evolved over time, but current international guidelines define CKD as decreased kidney function shown by GFR of less than 60 mL/min per 1·73 m2, or markers of kidney damage, or both, of at least 3 months duration, regardless of underlying cause . When GFR is less than 15 mL/min per 1·73m2 , a person has reached end stage kidney disease (ESKD), at which point kidney function is no longer able to sustain life over the long term. Options for patients with ESKD are kidney replacement therapy (in the form of dialysis or kidney transplantation), or conservative care (also called palliation or non-dialytic care Encephalopathy detected in patients with chronic kidney disease results from their exposure to several factors, such as uremia, hypertension, and fluid, and electrolyte disturbances (Brouns R, DyDeyn pp,2004) Uremic encephalopathy features include alterations of mental status (alertness and awareness alterations, poor concentration, psychosis, and hallucinations, without treatment of which stupor, and coma may develop) and motor system abnormalities, such as clouding of the sensorium as an early feature and delirium, seizures, and coma as late features (Palmer sc ,etal,2010)EEG is useful in assessing patients in uremic encephalopathy and in monitoring their progress. Electroencephalographic (EEG) findings correlate with clinical symptoms and, therefore, may be of diagnostic value. In addition, it can be useful to exclude other causes of confusion such as infection or structural abnormalities (Dijck Annemie Van,etal,2012). The EEG in uremic encephalopathy is generally abnormal, showing generalized slowing that becomes more severe as the condition worsens. EEG in CKD usually shows irregular low voltage with slowing of the posterior dominant alpha rhythm and occasional theta bursts. Prolonged bursts of bilateral, synchronous slow and sharp waves or spike and waves are characteristic. These changes stabilize with dialysis. EEG abnormalities in uremic encephalopathy is reflected through appearance of theta waves, disappearance of normal basic rhythms and diminished reactivity of EEG to afferent stimulation and domination by generalized delta activity. All these changes are mostly appreciated in the frontal leads (Al Arieff,Philadelphia,Ssaunders,2004)(Cl fraser, Arieff,Philadelphia,2001) A lot of studies have been done about uremic encephalopathy in acute renal failure patients. Very few data are available regarding EEG changes in CKD. This study evaluates the EEG findings in different stages of CKD.

Phase:
Study type: Observational

If steroid diabetes is not recognized in time, it will cause irreversible damage to the body. Nephropathy patients are more likely to have steroid diabetes ,the incidence rate up to 25%,due to hypoalbuminemia, high-dose hormone and other reasons, so they need to be closely followed up, identified and intervened in time.
