Renal transplantation : assessment of “at risk” diabetic foot and recommendations for mitigation

Abstract EN

We conducted a prospective study (between November 2013 and January 2015) to identify “foot at risk” in the diabetic renal transplant patients at a Tertiary Care Hospital in India.

Patients (151) were divided into three groups: diabetic transplant recipients (n = 42), new onset diabetes after transplantation (NODAT) (n = 59), and controls (nondiabetic renal transplant recipients) (n = 50).

Foot neuropathy and vasculopathy were assessed by standard methods.

Patients with “at risk” feet were given foot care advice.

Of the 151 patients, 144 patients were male and seven were female with a male:female ratio of 20:1.

Peripheral neuropathy was present among 42.9% of diabetic transplant patients, 35.6% of NODAT patients, and 12% of control patients.

Vasculopathy was present in 28.6% of diabetic transplant patients, 23.7% of NODAT patients, and 2% of control patients.

On multivariate analysis, patient’s age, mean time interval since transplantation, and HbA1c levels were significantly associated with neuropathy, whereas the duration of diabetes and vibration perception threshold was associated with vasculopathy.

After undergoing renal transplantation, a significant number of diabetic and NODAT patients has their “feet at risk” who in future may develop full-blown lesions of the diabetic foot.

Proper advice to patients and information to the treating doctor helps to mitigate the risk.
