Kidney function after solitary pancreas transplantation

Area of Science:

• Nephrology
• Transplantation Immunology
• Surgical Outcomes

Background:

• Preserving native kidney function post-pancreas transplantation is vital.
• Various factors can negatively affect kidney allograft or native kidney function after solitary pancreas transplantation (SPTx).

Purpose of the Study:

• To evaluate changes in kidney function over time in patients undergoing SPTx.
• To compare kidney function outcomes between pancreas after kidney (PAK) and pancreas transplant alone (PTA) recipients.

Main Methods:

• Retrospective analysis of serum creatinine (SCr) and calculated glomerular filtration rate (GFR).
• Tracking kidney function from baseline up to 3 years post-SPTx in PAK (n=61) and PTA (n=27) cohorts.

Main Results:

• 8% of all SPTx patients developed significant kidney failure (dialysis or re-transplant).
• Patients with baseline GFR < 60 mL/min/1.73 m2 had a 27% risk of kidney dysfunction; those with GFR > 60 mL/min/1.73 m2 had no significant decline.
• PAK recipients showed stable GFR, while PTA recipients experienced significant GFR decline (78 to 65 mL/min/1.73 m2) and SCr increase (1.03 to 1.28 mg/dL) within 1 year (P=.006 and P=.012, respectively).

Conclusions:

• Kidney function can deteriorate following SPTx, particularly in PTA recipients.
• Patient selection, especially considering baseline GFR, is critical for minimizing kidney complications after SPTx.
