Abstract:
Objective To understand the clinical and pathological characteristics of idiopathic membranous nephropathy,and to investigate their relationships in the elderly patients.Methods The clinical and pathological data of idiopathic membranous nephropathy diagnosed by renal biopsy in the recently 10 years in our hospital were retrospectively analyzed and compared.Results Sex composition variable was not significant between elderly and non-elderly groups,with male accounting for 57.4％ and 59.2％ respectively (P＞0.05).The ratio of idiopathic membranous nephropathy in primary glomerular disease was higher in the elderly than in non-elderly group (42.8％ vs.17.4％,x2 =119.058,P＜0.01).The course of the disease,the occurrence of edema,hypertension,levels of blood urea nitrogen,serum creatinine,blood IgG,IgA and IgG/IgM ratio were higher,while glomerular filtration rate and blood IgM level were lower in elderly group than in non-elderly group (all P＜0.05).The risk for membranous nephropathy was higher in elderly than in non-elderly group (Z=-5.853,P＜0.01).Nephrotic syndrome was common in the clinical diagnosis in the two groups,but it was more common in elderly group than in non-elderly group (x2 =6.825,P=0.033).Membranous nephropathy stage Ⅱ was common in the two groups,and there were no significant differences in the pathological stages,clinical manifestations and their relationships between the two groups (all P＞0.05).Conclusions The risk for idiopathic membranous nephropathy is higher in elderly group than in non-elderly group.Edema,hypertension and renal dysfunction occur more commonly in elderly patients with idiopathic membranous nephropathy.
