Registered date:08/03/2022
A single-arm pilot study to evaluate changes in renal function and safety of steroid pulse therapy in renal transplant patients with advanced tertiary lymphoid tissues
Basic Information
Recruitment status | Recruiting |
---|---|
Health condition(s) or Problem(s) studied | Advanced tertiary lymphoid tissues |
Date of first enrollment | 18/05/2022 |
Target sample size | 30 |
Countries of recruitment | |
Study type | Interventional |
Intervention(s) | methylprednisolone 500 mg intravenous administration for 3 days. Kidney biopsy; 365 +-45 days after steroid pulse therapy |
Outcome(s)
Primary Outcome | Changes in presence/absence and stage of TLTs before and after 1 year of treatment |
---|---|
Secondary Outcome | 1) Evaluate the change in Banff scores of biopsies before the treatment (immediately after kidney transplantation and during the first year of kidney transplantation) and one year after the treatment (two years after kidney transplantation) 2)Compare the rate of change in eGFR before the treatment (from 1 month after kidney transplant to the treatment) and after treatment intervention (from the treatment to 2 years after kidney transplant) 3)Compare the rate of change in eGFR before the treatment (from 1 month after kidney transplantation to the treatment) and after the treatment with the rate of change in eGFR in patients diagnosed with advanced tertiary lymphoid tissue in the previous study (unpublished data). 4)To confirm the safety of steroid pulse, blood glucose levels (fasting blood glucose, hemoglobin A1c) and dyslipidemia (triglyceride, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol) will be compared before and after the start of treatment. In addition, the presence of adverse events such as femoral neck fracture will be checked. |
