ABSTRACT
Objective:
To investigate the influencing factors of non-remission of proteinuria in patients with nephrotic syndrome (NS) and idiopathic membranous nephropathy (IMN).Methods:
The study was a retrospective observational study. The clinical data of patients with NS who were diagnosed as IMN by renal biopsy and serum albumin recovered normal after six months of treatment were collected from Beijing Anzhen Hospital, Capital Medical University from June 1, 2010 to January 31, 2022. Patients were divided into proteinuria remission group and non-proteinuria remission group according to whether urinary protein < 3.5 g/24 h and decreased 50% from the onset. The differences of clinical and pathological characteristics between the two groups at baseline were compared. The logistic regression model was used to analyze the influencing factors of non-remission of proteinuria.Results:
Ninety-five NS patients with renal pathology of IMN were included in this study, with age of 57(43, 65) years old and 50 males (52.6%). There were 75 patients in the proteinuria remission group and 20 patients in the non-proteinuria remission group. Compared with the proteinuria remission group, the non-proteinuria remission group had higher baseline body mass index [(26.83±4.03) kg/m 2vs. (24.68±3.97) m 2, t=-2.149, P=0.034] and proportion of overweight (85.0% vs. 58.7%, χ2=4.765, P=0.029), and larger waist circumference [88.5(85.3, 101.5) cm vs. 87.0(77.5, 92.0) cm, Z=2.362, P=0.018]. Renal pathological results showed that the proportions of diabetes nephropathy (10.0% vs. 0, P=0.043) and glomerular hypertrophy (45.0% vs. 20.0%, χ2=5.227, P=0.022) were higher, and the average diameter of hypertrophic glomeruli was longer [(197.96±6.37) μm vs. (193.51±8.50) μm, t=2.029, P=0.041] in the proteinuria remission group than those in the non-proteinuria remission group. Multivariate logistic regression analysis results showed that waist circumference was an independent influencing factor of non-proteinuria remission in patients with IMN under waist circumference > 90 cm in men and >85 cm in women ( OR=1.083, 95% CI 1.005-1.168, P=0.037).Conclusion:
Abdominal obesity is an independent risk factor of non-remission of proteinuria in NS patients with IMN after early treatment.
