Incidence and factors associated with prescribing renin-angiotensin-system inhibitors in adult idiopathic nephrotic syndrome: A nationwide cohort study. J Clin Hypertens (Greenwich) 2021; 23:999-1007. [PMID: 33645883 PMCID: PMC8678837 DOI: 10.1111/jch.14224] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Revised: 02/02/2021] [Accepted: 02/03/2021] [Indexed: 11/27/2022]
Abstract
Angiotensin‐converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are prescribed as conservative or adjunctive therapies for adult idiopathic nephrotic syndrome. However, studies on real‐world practice patterns are scarce. This study aimed to examine the prevalence and incidence of ACEI/ARB prescription and their associated factors. This nationwide cohort study included adult Japanese patients with idiopathic nephrotic syndrome including minimal change disease (MCD), membranous nephropathy (MN), focal segmental glomerulosclerosis (FSGS), and others. The outcomes were the prevalence of ACEI/ARB prescription at baseline (date of renal biopsy or date of immunosuppressant initiation) and at 2 months after baseline. Of the 326 eligible patients, 122 (37.4%) had already been prescribed ACEIs/ARBs. Of the remaining 204 patients, 67 (32.7%) were newly prescribed within the 2‐month period. MN/FSGS (vs. MCD, adjusted odds ratio [AOR]: 4.96 [95% confidence interval {CI} 2.53–9.72] and 3.95 [95% CI 1.61–9.66], respectively), higher age (per 1‐yr increase, AOR: 1.02 [95% CI 1.00–1.04]), other hypertensive agents (AOR: 2.18 [95% CI 1.21–3.92]), antidiabetic drug (AOR: 6.57 [95% CI 1.77–24.4]) were associated with a higher prevalence of ACEI/ARB prescription. MN (vs. MCD, AOR: 6.00 [95% CI 2.57–14.0]) and higher baseline systolic blood pressure (SBP) (per 10‐mmHg increase, AOR: 1.36 [95% CI 1.09–1.70]) were associated with a higher incidence of ACEI/ARB prescription. On average, incidence of ACEI/ARB prescription increased from 19.2% to 40.8% as baseline SBP increased from 100 to 140 mmHg. Thus, Japanese nephrologists are likely to prescribe ACEIs/ARBs for nephrotic patients with MN or high baseline SBP, even below the hypertensive range.

Novel ELISA for thrombospondin type 1 domain-containing 7A autoantibodies in membranous nephropathy. Kidney Int 2020; 95:666-679. [PMID: 30784662 DOI: 10.1016/j.kint.2018.10.024] [Citation(s) in RCA: 57] [Impact Index Per Article: 14.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2018] [Revised: 09/18/2018] [Accepted: 10/11/2018] [Indexed: 11/28/2022]
Abstract
Autoantibodies against phospholipase A2 receptor 1 (PLA2R1) and thrombospondin type 1 domain-containing 7A (THSD7A) are emerging as biomarkers to classify membranous nephropathy (MN) and to predict outcome or response to treatment. Anti-THSD7A autoantibodies are detected by Western blot and indirect immunofluorescence test (IIFT). Here, we developed a sensitive enzyme-linked immunosorbent assay (ELISA) optimized for quantitative detection of anti-THSD7A autoantibodies. Among 1012 biopsy-proven MN patients from 6 cohorts, 28 THSD7A-positive patients were identified by ELISA, indicating a prevalence of 2.8%. By screening additional patients, mostly referred because of PLA2R1-unrelated MN, we identified 21 more cases, establishing a cohort of 49 THSD7A-positive patients. Twenty-eight patients (57%) were male, and male patients were older than female patients (67 versus 49 years). Eight patients had a history of malignancy, but only 3 were diagnosed with malignancy within 2 years of MN diagnosis. We compared the results of ELISA, IIFT, Western blot, and biopsy staining, and found a significant correlation between ELISA and IIFT titers. Anti-THSD7A autoantibodies were predominantly IgG4 in all patients. Eight patients were double positive for THSD7A and PLA2R1. Levels of anti-THSD7A autoantibodies correlated with disease activity and with response to treatment. Patients with high titer at baseline had poor clinical outcome. In a subgroup of patients with serial titers, persistently elevated anti-THSD7A autoantibodies were observed in patients who did not respond to treatment or did not achieve remission. We conclude that the novel anti-THSD7A ELISA can be used to identify patients with THSD7A-associated MN and to monitor autoantibody titers during treatment.

Abstract
AIM To analyze the clinical and morphological manifestations of membranous nephropathy (MN) and to evaluate the efficiency of its therapy. MATERIAL AND METHODS MN cases in 2009 to 2016 were retrospectively detected with a subsequent analysis of patients with primary MN (PMN). The titer of IgG-autoantibodies to phospholipase A2 receptor (anti-PLA2R Ab) was determined by an indirect immunofluorescence assay. Treatment outcomes, such as the time course of changes in proteinuria, nephrotic syndrome (NS), and the development of complete and partial remissions (CR and PR), were assessed. RESULTS MN was detected in 201 cases; the secondary etiology of the disease was established in 24.9%. The prevalence of MN among morphologically confirmed glomerulopathies was 14%; that of PMN was 10.4%. The median period to diagnosis PMN was 8 (5; 19) months. 150 patients with PMN (66.7% were men; age was 50±15 years) were distributed according to the following morphological stages: Stages I (23.9%), II (48.5%), III (26.1%), and IV (1.5%). Elevated anti-PLA2R Ab levels were found in 51.6% of cases; NS in the presence of proteinuria was detected in 85.6% of patients. An estimated glomerular filtration rate (eGFR) of <60 ml/min/1.73 m2 was seen in 25% of cases. Treatment outcomes were evaluated in 80 cases; the median follow-up period was 19 (8; 40) months. 68% of cases had CR (32%) or PR (36%) with a median follow-up of 26 (13; 44) months. Spontaneous CRs or PRs were observed in 7.5% of the patients. Multivariate analysis showed that the probability of CR or PR increased 3.2-fold in the use of cyclophosphamide and/or cyclosporine and decreased as eGFR dropped. CONCLUSION In Russia, PMN is a common type of glomerulopathy, the specific features of which should include the low rates of spontaneous remissions and detection of anti-PLA2R Abs. For renal protection, the majority of patients with PMN require timely diagnosis and treatment; individualization of the choice of treatment and its enhanced efficiency call for further investigations.
