Background: Acute kidney injury (AKI) is defined as a failure in renal function leading to insufficiency of fluid and electrolyte homeostasis. Thus, sensitive biomarkers of renal tubular injury are needed to detect AKI earlier. In this study, urinary beta 2-microglobulin (β2-MG) and urinary N-acetyl-β-D-glucosaminidase (NAG) were evaluated for AKI prognosis/diagnosis in pediatric patients suffering different cancers prescribed with Ifosfamide, Ifosfamide plus Carboplatin, and Ifosfamide plus Cisplatin.
Materials and Methods: In this prospective study done in Isfahan, Iran, urinary β2-MG, urinary NAG, blood urea nitrogen (BUN), and serum and urinary creatinine (Cr) were measured in 40 pediatric cancer patients less than 16 years old in three age groups during 61 courses of chemotherapy on day 0, three and six after the treatment.
Results: Using ANOVA and t-test, the mean levels of urinary β2-MG (p= 0.001), urinary β2-MG/Cr (p= 0.003) and urinary NAG/Cr (p= 0.001), before and on day six of the treatment were statistically significant (p< 0.05). Also, the mean levels of BUN (p= 0.01), urinary β2-MG (p= 0.001), β2-MG/Cr (p= 0.001) and NAG/Cr (p= 0.004) based on the gender groups, the mean levels of urinary NAG (p=0.001), NAG/Cr (p= 0.001) and β2-MG/Cr (p= 0.008) based on three age groups, and the mean levels of serum Cr (p= 0.047), urinary β2-MG (p= 0.005), β2-MG/Cr (p= 0.032) and NAG/Cr (p= 0.032) based on the Ifosfamide dosage were statistically significant during the time of the treatment.
Conclusion: Urinary β2-MG, urinary β2-MG/Cr, and urinary NAG/Cr are more significant biomarkers than serum Cr in earlier diagnosis and treatment of AKI in cancer patients. However, urinary NAG should be further studied to prove its reliability for AKI prognosis/diagnosis. It is suggested that urinary NAG can be used along with other renal biomarkers such as urinary β2-MG, kidney injury molecule-1(KIM-1), or interleukin-18 (IL-18) for AKI prognosis/diagnosis.
