Urinary CXCL9 and CXCL10 levels show promise in predicting T cell-mediated rejection after kidney transplants. Measuring these chemokines in urine may offer a new diagnostic tool for early detection of transplant rejection.
Area of Science:
- Nephrology
- Immunology
- Transplantation Science
Background:
- Monitoring serum chemokines CXCL9 and CXCL10 is a potential non-invasive method for detecting transplant rejection.
- Early detection of renal transplant rejection is crucial for graft survival.
Purpose of the Study:
- To investigate the relationship between urinary levels of CXCL9 and CXCL10 and graft function following renal transplantation.
- To assess the predictive value of urinary chemokines for renal transplant rejection.
Main Methods:
- A study involving 75 living-related donor renal transplant recipients.
- Urinary chemokine levels (CXCL9 and CXCL10) were measured pre-operatively and at multiple time points post-transplantation using enzyme-linked immunosorbent assay.
- Clinical variables and biopsy-proven rejection were monitored throughout the follow-up period.
Main Results:
- Urinary CXCL9 and CXCL10 levels were significantly higher in patients with biopsy-proven rejection compared to those without rejection, particularly on post-operative days 1 and 7, and at the time of rejection.
- Serum creatinine levels correlated strongly with urinary CXCL9 and CXCL10 levels at the time of rejection.
- In T cell-mediated rejections, urinary CXCL10 levels increased significantly.
Conclusions:
- Urinary CXCL9 and CXCL10 levels may serve as predictive markers for T cell-mediated rejection in the early post-transplantation period.
- Measuring urinary CXCL9 and CXCL10 offers a potential additional diagnostic tool for identifying renal transplant rejection.

Factors Affecting Renal Clearance: Drug's Physicochemical Properties and Plasma Levels
One important factor is the drug's molecular size. The kidneys readily excrete smaller molecules below 300 Daltons (Da). On the other hand, molecules weighing between 300 and 500 Da are excreted through both urine and bile. Larger molecules above 500 Da tend to be excreted...
Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...
Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
