Abstract:
Objective To explore the applied value of urine light chainκ、λand κ/λ ratio test in older people with B cell malignant proliferative disease.Methods Young volunteers, general older patients, kidney failure older patients and older patients with B cell malignant proliferative disease were selected and immunoephe-lometry method was applied to detect the level of urine light chainκ、λ and κ/λ ratio.Result The average levels (mg/L)of urine light chain κand λin older patients with kidney failure group(172.00 ±188.10,111.50 ± 109.32)were higher than that in general older patients group(32.72 ±33.60,15.02 ±15.58).In each of the ol-der patients groups,the levels of urine light chainκandλwere higher than that in young volunteers groups(9.30 ±5.80,4.97 ±2.61).The κ/λ ratios of urine light chain in older patients with kidney failure group(1.59 ± 0.4),general older patients group(2.19 ±0.54)and young volunteers group(1.92 ±0.48)were consistent,how-ever,it was significantly abnormal in older patients with B cell malignant proliferative disease group,the ratio was high inκtype(44.8 ±83.17)and low inλtype(0.06 ±0.08).After effective treatment, κ/λ ratio of urine light chain in older patients with B cell malignant proliferative disease tended to normal.Conclusion The level of u-rine light chainκandλis effected by renal function,but not involved the κ/λ ratio.B cell malignant proliferative disease significantly affects theκ/λratio of urine light chain.Constantly monitoring the change ofκ/λratio of u-rine light chain in older peoples with B cell malignant proliferative disease can reflect the proliferative degree of malignant B cell in vivo.
