Abstract
Introduction: Chronic kidney disease (CKD) may increase morbidity and mortality. Therefore, early detection of inflammation in kidney transplant recipients with a high risk of transplant rejection is important.
Objectives: This study was conducted to compare serum levels of pentraxin-3 (PTX-3), mannose binding lectin (MBL) and high sensitivity C-reactive protein (hs-CRP) in patients with chronic renal failure before and after transplantation.
Patients and Methods: This cross-sectional study was carried on 18-80 years old patients receiving immunosuppressive therapy who underwent kidney transplantation in Shahid Beheshti hospital of Babol in 2016. Before transplantation, one week later and two months after transplantation, the serum levels of PTX-3, MBL and hs-CRP were determined. Complications including acute transplant rejection and urinary tract infection were recorded since inflammatory markers were evaluated and compared at the time of complication.
Results: The mean age of the patients was 42.07±12.47 years. Transplant rejection and urinary tract infection occurred in 3 (10%) and 4 (13.3%) of patients, respectively. Patients over 55 years of age and those with hypertension had significantly more complications (P=0.03 and P=0.02 respectively). Two months after transplantation, PTX-3 and MBL levels were significantly lower (PTX-3; 10.84±15.88 versus18.75±24.31 ng/dL, P=0.001 and MBL; 764.3±771.35 versus 1157.9±1299.75 ng/dL, P=0.006). In patients with complications, PTX-3, MBL and hs-CRP levels were 16.73±27.98 ng/dL, 710.0±613.19 ng/dL and 8.43±12.10 mg/L, respectively. No significant difference was found between inflammatory markers in complicated and uncomplicated patients. Comparison of changes in PTX-3, MBL and hs-CRP levels before and after transplantation showed a significant difference two months following transplantation compared to pre-transplantation and also one week after it for PTX-3 and MBL (PTX-3: P=0.001 and P=0.009, respectively; MBL: P=0.006 and P=0.03, respectively).
Conclusion: Based on the results of this study, PTX-3 and MBL levels can be considered for determining the inflammatory status of kidney transplant patients and the prognosis of transplantation.
