About this study

Official title: Histological and Clinical Biomarkers to Predict the Progression of IgA Nephropathy

IgA nephropathy (IgAN) is the most prevalent primary glomerular disease worldwide and an important cause of end stage renal disease. IgAN has an incidence of 8-25 new cases/year/per million age-related population in adults and 3-5/new cases/year/per million age-related population in children and progresses to need of renal replacement treatment in 5-15% at 10 years and in about 20% at 20 years. The variability of the clinical course anticipates different treatment options. There is an absolute need of validated biomarkers to predict risk of progression and indication for treatment at early stages, when lesions can be reversible. This study aimed to evaluate IgAN progression and its histological and clinical correlates.

Read the detailed description

IgA nephropathy is the most prevalent primary glomerular disease worldwide and an important cause of end stage renal disease. Clinical course varies from long term stable renal functions with minimal proteinuria and microscopic hematuria to rapidly progressive glomerulonephritis with crescents on renal biopsy which progresses to end stage renal disease in a very short time.

In current practice the diagnosis is made with renal biopsy. A less invasive procedure for diagnosis is not present and no serum biomarkers for clinical follow-up, treatment response and prognosis are available. For that reason follow-up of the disease is enabled with indirect markers of renal function like proteinuria, serum creatinine and glomerular filtration rate. These markers are not specific for IgA nephropathy. The lack of disease specific markers hinders the standardization of patient follow-up and treatment. Development of specific and sensitive, repeatable, histopathological and clinical markers for diagnosis, follow up and treatment response in IgA nephropathy the most prevalent primary glomerular disease affecting many patients worldwide will offer prospects of diagnosis and improved prognostication.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Progression to end stage renal disease or two-fold increase in serum creatinine level as compared to baseline

Secondary outcomes (1)
  1. Resistance of proteinuria

    Resistance of proteinuria defined as no improvement in the daily proteinuria levels or >1 g/24 hr proteinuria

    Measured: 36 months

Questions about this trial

What is this clinical trial studying?

An observational study of IgA Nephropathy and Glomerular Diseases, run by Istanbul University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Aug 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression to end stage renal disease or two-fold increase in serum creatinine level as compared to baseline (time frame: 36 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Aug 2015.
