Leukodepletion improves renal function in patients with renal dysfunction undergoing on-pump coronary bypass surgery:...

Area of Science:

• Cardiology
• Nephrology
• Transfusion Medicine

Background:

• On-pump coronary artery bypass grafting (CABG) can impact renal function.
• Leukodepletion is a technique used during blood transfusions.

Purpose of the Study:

• To evaluate the effect of leukodepletion on renal function in patients undergoing on-pump CABG.
• To assess if leukodepletion can prevent renal impairment and tubular damage.

Main Methods:

• Fifty patients with normal preoperative cardiac function and mild renal dysfunction were randomized into two groups.
• Group A (n=25) underwent on-pump CABG with leukodepletion; Group B (n=25) underwent on-pump CABG without leukodepletion.
• Renal injury was assessed using plasma creatinine, blood urea nitrogen (BUN), and urinary alpha glutathione S-transferase (GST).

Main Results:

• The leukodepletion group showed decreased levels of creatinine, BUN, and urinary GST post-surgery compared to the control group.
• No mortality was observed in either group.
• Three patients in the control group required postoperative dialysis, while none in the leukodepletion group did.

Conclusions:

• Leukodepletion appears beneficial in preventing renal impairment and tubular damage in patients with renal dysfunction undergoing on-pump CABG.
• The findings suggest leukodepletion is a valuable strategy to preserve kidney function in this patient population.
