Clinical Trial Summary
The purpose of the study is to determine how much a persons kidney function recovers after
receiving a simultaneous liver kidney transplant. The investigators will be contacting
patients with kidney dysfunction with estimated GFR between 25 and 40 (not on dialysis
treatment) who are listed to receive a simultaneous liver kidney (SLK) transplant to look at
this function recovery. The investigators hope to develop a criteria based on GFR
measurement, kidney function calculations from native kidneys vs transplanted kidney and
compare the contributions, and correlate with estimated GFR on basic metabolic panel (BMP: a
blood test) to predict higher chances of recovery of native kidney function.
Description:
Study design
Study will be a pilot longitudinal prospective study. SLK transplant listed patients will be
recruited from the outpatient Liver Kidney Transplant Clinic at Medical Diagnostic Clinic
(MDC) as well as inpatients admitted to IU University Hospital. Listing status for SLK
transplant will be confirmed and patients will be scheduled for a Mag3 nuclear medicine scan
at IU University Department of Nuclear medicine. For study purposes, this scan will be done
pre and post-transplant to compare the results.
Methods:
Inclusion/Exclusion criteria:
Inclusion:
1. > 18 years old
2. Listed for Liver Transplant for ESLD and Kidney Transplant based on eGFR ranging from ≥
25 to ≤40 mL/min/1.73m2 (not on dialysis at time of surgery)
3. Candidates with two native kidneys.
4. Willing to participate and sign informed consent form.
Exclusion Criteria:
1. Unstable patients (e.g. in the ICU or those who are on Continous Renal Replacement
Therapy (CRRT) who cannot complete the nuclear medicine scan or those on Hemodialysis
2. Prior history of any solid organ transplant.
3. Those who are currently pregnant or breast feeding.
4. Patients with a history of Adult Polycystic Kidney Disease
Data collection: Data collection will be done in RedCap©️ These data forms will incorporate a
comprehensive list of variables:
1. Participants demographics and BMI
2. Reason for ESLD and complications listed in Medical Chart
3. Medication list
4. Results of Nuclear medicine scan, eGFR on Basic Metabolic Panel, measurement of eGFR by
Cystatin C, 24 hour urinary creatinine clearance and measurement of urinary NGAL level.
Radiographically: kidney size, presence of findings such as cysts, stones etc.
5. Post SLK transplant complications including need for Dialysis, delayed graft function,
episodes of rejection, infections and any reason for admission to the hospital
6. Adherent to Immunosuppression regimen, and type of Immunosuppression regimen
7. BP readings at follow up clinic visits
8. Any post SLK transplant imaging for kidney size and any findings (if any imaging is
performed for any other indication, none will done for the research study).
Participants will be informed about the results of their studies. Participation will be
voluntary. Compensation will be provided once in the form of $25 gift card that will be
provided upon completing participation for the nuclear medicine scan 10 months after patients
receive their SLK transplant. Patients and their insurance will not be charged and the
testing will be invoiced to the study grant.
Provisions for post-study care No provision will be provided for care regarding incidental
findings on the nuclear medicine scan. They will be given information regarding referral to
seeking appropriate care. No expenses will be reimbursed for this care.
Participant timeline:
Enrollment of participants will be done starting February 2023 and completed by December 2023
Statistical Analyses:
Sample size:
Estimated number of participants is determined by participants listed for SLK transplant. An
estimated 15 participants are planned to be recruited. As this is a pilot study, all
participants at IU will be asked to participate with a future goal of a multi-center study.
Plans for assessment and collection of outcomes:
Data will be collected in IU RedCap registry, which is a secure platform. Data will be
entered in Redcap, coded, secured, and stored. Any raw data collection (source documents)
will be kept in a locked cabinet in a locked office. Data will be processed with SPSS data
management software.
Confidentiality Information about potential and enrolled participants will be collected,
shared, and maintained in a manner that protects confidentiality before, during, and after
the study.
