Summary
Pancreas transplantation alone (PTA) leads to significant kidney function decline, evidenced by decreased estimated glomerular filtration rate (eGFR) and increased serum creatinine (SCr). Monitoring renal impairment risk factors is crucial post-PTA.
Area of Science:
- Nephrology
- Transplantation Medicine
- Immunology
Background:
- Investigated kidney function changes in patients undergoing pancreas transplantation alone (PTA).
- Cohort study from January 2002 to December 2011.
- Focused on patients with functioning grafts for at least one year.
Purpose of the Study:
- To analyze longitudinal changes in kidney function after PTA.
- To assess serum creatinine (SCr) and estimated glomerular filtration rate (eGFR) trends.
- To identify potential risks for renal impairment post-transplant.
Main Methods:
- Recruited 10 PTA patients with functioning grafts >1 year.
- Measured SCr and eGFR (Levey-MDRD) at baseline, 6 months, 1, 3, and 5 years.
- Mean follow-up was 75.7 months.
Main Results:
- eGFR significantly decreased by up to 22.6% at 5 years post-transplant (P < .05).
- SCr significantly increased by up to 22% at 5 years post-transplant (P < .05).
- 3/7 patients had eGFR <60 at 5 years; no patient required dialysis or kidney transplant.
Conclusions:
- Kidney function significantly deteriorates following pancreas transplantation alone.
- Understanding risk factors for renal impairment is vital for patient selection and kidney preservation.
- Further research needed to mitigate post-PTA renal decline.

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...
01:28Kidney Transplant I: Introduction
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...
01:16Kidney Transplant III: Nursing Management
Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
