Abstract:
Objective:To analyze and compare the clinicopathological characteristics in low weight proteinuria(LWP) and nephrotic proteinuria(NP) multiple myeloma(MM) patients with renal involvement.Methods:From October 1991 to October 2005,46 patients with MM were diagnosed in the Research Institute of Nephrology of Jinling Hospital(Nanjing,China).Renal biopsies were done in 41 of them.The patients were devided into two groups,LWP and NP groups.Their clinical and pathological features were investigated and compared. Results:The epidemiological features and type of MM in LWP and NP groups were similar.The patients in LWP group had higher incidence of D-S Ⅲ stage and heavier anaemia compared to NP group.Compared to patients in NP group,patients in LWP group had higher incidence of renal insufficiency and lower urine osmotic pressure.Part of patients checked urine N-acetyl-?-glucosaminidase,RBP and there were no difference between two groups.Cast nephropathy was the most frequent pathologic type in LWP group,while light chain deposition disease and glomerular amyloidosis were the most common pathologic type in NP group.Conclusion:According to this study,we get the conclusion that proteinuria analysis may be a significant test to evaluate the clinicopathological characteristics of MM patients with renal involvement.
