The Correlation of Periostin and Renal Pathology in Chronic Kidney Disease Patients

July 8, 2015 updated by: Chulalongkorn University

Potential of Periostin as a Tissue and Urinary Biomarker in Lupus Nephritis and IgA Nephropathy Patients

The purpose of this study is to determine the location of periostin and urine periostin level in patients with lupus nephritis and IgA nephropathy.

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.

Detailed Description

Total of 50 lupus nephritis and IgA nephropathy patients who met the inclusion criteria were included in this study. The information sheet and informed consent will be obtained before collecting the patient's data. All patients were interviewed for collecting demographic data and laboratory testing were reviewed from patient's record. Kidney tissue and urine sample were collected at the biopsy date from patients.Kidney tissue were stained with hematoxylin and eosin (H&E), Masson's trichrome solution and immunohistochemistry for periostin. The location of periostin staining in kidney tissue were assessed by renal pathologist.

The total of 50 urine samples from patients and 50 urine samples from healthy controls were measured for periostin level by enzyme-linked immunosorbent assay. The Mann-Whitney rank-sum test was used for comparing urine periostin level between patients and healthy controls and also other variables between patients with urine periostin detection and without urine periostin detection. Spearman correlation coefficients were used test correlations between urine periostin level in patients and other variables. Receiver operating characteristic curves was generated to calculate the area under the curve and find the best cutoff value of urine periostin level for distinguishing patients from healthy controls. P-values < 0.05 were considered statistically significant.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

18 years and older (ADULT, OLDER_ADULT)

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
Time Frame
Urine periostin level in lupus nephritis and IgA nephropathy patients compared with healthy controls
Time Frame: 2 years
2 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

Correlation of urine periostin level in lupus nephritis and IgA nephropathy patients and other variables

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.
April 1, 2013

Primary Completion (Actual)

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
