  • Research summary

    Chronic allograft damage (CAD) is a significant cause of graft failure following renal transplantation. Characterised by fibrosis (scarring), it leads to the failure of up to 5% grafts annually and there are no specific therapies available. Two significant challenges face the transplant community in the context of CAD: discovery of potential therapies and early diagnosis, and the proposed investigation incorporates both these aspects, using a combination of imaging and molecular techniques. We have evidence to show that microRNA-214 (miR-214) plays an important role following renal injury as in a potential therapeutic target in the context of CAD. We also have evidence that it maybe a potential biomarker of fibrosis in a small cohort of patients with CAD on biopsy.

    MR elastography (MRE) is a form of MRI that has been successfully used as an alternative to biopsy in patients with liver fibrosis and small studies have shown MRE can image fibrosis in other organs including kidney transplants.

    We will recruit renal transplant recipients undergoing clinically indicated biopsies, and obtain serum and urine samples for assessment of miR-214 expression, as well as offering them to undergo MRE. We will determine whether miR-214 and MRE may provide useful diagnostic information when correlated with biopsy findings. Ultimately, we aim to demonstrate early fibrosis so that treatment can be instituted before there is a significant loss of kidney function. Importantly, this may also be used to track fibrosis, thus avoiding the need for repeated invasive biopsies.

    Patients will be recruited from clinic. Consultants will identify suitable patients and pass details to the clinical research fellow.

    Information from the scans WILL NOT be used influence treatment of participants.

    We have full funding from Kidney Research UK.
