Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A total of 1200 patients diagnosed as primary IgA nephropathy with nephrotic proteinuria will be enrolled among 25 pediatric nephrology medical centers nationwide, according to the following protocol.

  1. Establishment of registration database online.
  2. Participants will be enrolled according to the inclusion criteria and exclusion criteria.
  3. The following data will be collected prospectively, including demographic data, clinical symptoms, physical examination, laboratory examination, renal pathology, treatment protocol and follow-up.
  4. SPSS software (version 14.0; SPSS, Inc., Chicago, IL, USA) will be used for statistical analysis. P value less than 0.05 will be considered significant.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 month to 18 years (Child, Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Improvement of proteinuria
Time Frame: Two years
Complete remission is defined as 24-hour urine protein<150mg or UPC<0.3 g/g with normal kidney function. Partial remission is defined as urine protein decreased by more than 50% with normal renal function.
Two years
Renal dysfunction
Time Frame: Two years
Renal dysfunction is defined as eGFR declined by more than 50%.
Two years
Hypertension
Time Frame: Two years
Hypertension is defined as blood pressure higher than age-specific average level. Use of antihypertensive drugs will be recorded.
Two years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
End stage renal disease(ESRD)
Time Frame: Two years
ESRD is defined as eGFR<15ml/min/1.73m2, initiation of long-term dialysis or kidney transplant.
Two years
Mortality
Time Frame: Two years
Death of participants will be recorded.
Two years

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
