Abstract:
Objective To retrospectively analyze the clinical epidemiology features of adult idiopathic membranous nephropathy (IMN) in Zhongshan Hospital,and to investigate their therapeutic effect and its possible influence factors.Methods A total of 183 patients admitted to the Zhongshan Hospital of Fudan University and diagnosed as IMN by renal biopsy from January 2013 to December 2015 were involved.Their baseline information including demographics and pathologic was collected.Patients were followed up for at least 12 months.Serum albumin ＜ 30 g/L and 24 h urine protein ＞ 3.5g were defined as nephrotic syndrome (NS).IMN patients were divided into NS and non-NS groups and compared.Furthermore,the baseline data of remission and no remission patients were compared,and the correlations of their baseline data with conservative and immunosuppressive therapy were assessed by logistic regression analysis.Results (1) IMN accounted for 11.1％ of renal biopsy cases in our hospital,with an average age of 57 years and 59.6％ male patients.(2) Compared with patients without NS,IMN patients with NS were older,had a shorter time from the onset to receive renal biopsy,lower estimated glomerular filtration rate,and higher total cholesterol,low density lipoprotein cholesterol,triglyceride and serum creatinine (all P ＜ 0.05).(3) The effective rate of conservative treatment in IMN patients without NS was 65.7％,and the ineffective group had higher triglyceride compared with the effective group (P=0.019).(4) The effective rate of immunosuppressive therapy in IMN patients with NS was 81.2％,and low serum albumin was an independent risk factor for the poor efficacy of immunosuppressive therapy (OR=1.202,95％ CI 1.003-1.440,P=0.046).(5) The effective rate of conservative treatment in IMN patients with NS was 55.5％,and low serum albumin was an independent risk factor for the poor efficacy of conservative treatment (OR=1.629,95％CI 1.047-2.536,P=0.023).Conclusions The detection rate of IMN is increasing year by year,but the remission rate of conservative treatment is still not low in mild and moderate patients.For the patients without NS,high triglyceride may predict a poor effect of conservative treatment.Hypoproteinemia is a predictor of poor effect,no matter what a NS patient takes immunosuppressive therapy or conservative treatment.
