Retrospective Analysis of Renal Prognosis in Patients With Chronic Kidney Disease

June 28, 2017 updated by: National Taiwan University Hospital
During 1993 and 2006, a total of 987 patients older than 20 years underwent native kidney biopsy at the Renal Division of this hospital. 404 patients with membranoproliferative glomerulonephritis and mesangioproliferative glomerulonephritis, and patients with secondary glomerulonephritis or other renal pathologies, such as diabetic nephropathy, lupus nephritis, rapid progress glomerulonephritis, acute tubular necrosis, and tubulointerstitial nephritis will be analyzed. The demographic characteristics and laboratory data of these patients at presentation or before renal biopsy will be recorded. These data included parameters such as age, sex, diabetes, hypertension, immunosuppressants treatment, BUN, serum creatinine, albumin, hemoglobin, total cholesterol, triglycerides, and urine protein. All subjects will be followed until 2015 for occurrence of primary endpoints, including all-cause death or ESRD requiring long-term dialysis or renal transplantation. A total of 433 patients who had been followed for 3 years during 2003 and 2007 will receive regular clinic follow-up. GFR will be estimated according to the Modification of Diet in Renal Disease (MDRD) abbreviated formula: 186 x Scr -1.154 x age -0.203 x 0.742 (if female). CKD stage will be determined as described by the National Kidney Foundation of the United States. At the time of entry, GFRs of 30-59, 29-15 and < 15 ml/min/1.73 m2 for more than 3 months will be classified as CKD stages 3, 4 and 5, respectively. Baseline Data of the 433 patients are used as recorded at the beginning during 2003 and 2007. The observation period of each patient is defined to start immediately after the registered measurement of serum creatinine satisfying the above criteria (designated as the index date) and lasted until ESRD or end of 2015. ESRD is defined as initiation of RRT, i.e. chronic dialysis or renal transplantation.

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

Study Major Dates

Study Start (Actual)

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.
June 20, 2017

Primary Completion (Anticipated)

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.
