Background and objectivesSocial deprivation is a recognized risk factor for undifferentiated CKD; however, its association with glomerular disease is less well understood. We sought to investigate the relationship between socioeconomic position and the population-level incidence of biopsy-proven glomerular diseases.Design, setting, participants, & measurementsIn this retrospective cohort study, a provincial kidney pathology database (2000–2012) was used to capture all incident cases of membranous nephropathy (n=392), IgA nephropathy (n=818), FSGS (n=375), ANCA-related GN (ANCA-GN, n=387), and lupus nephritis (n=389) in British Columbia, Canada. Quintiles of area-level household income were used as a proxy for socioeconomic position, accounting for regional differences in living costs. Incidence rates were direct standardized to the provincial population using census data for age and sex and were used to generate standardized rate ratios. For lupus nephritis, age standardization was performed separately in men and women.ResultsA graded increase in standardized incidence with lower income was observed for lupus nephritis (P<0.001 for trend in both sexes) and ANCA-GN (P=0.04 for trend). For example, compared with the highest quintile, the lowest income quintile had a standardized rate ratio of 1.7 (95% confidence interval, 1.19 to 2.42) in women with lupus nephritis and a standardized rate ratio of 1.5 (95% confidence interval, 1.09 to 2.06) in ANCA-GN. The association between income and FSGS was less consistent, in that only the lowest income quintile was associated with a higher incidence of disease (standardized rate ratio, 1.55; 95% confidence interval, 1.13 to 2.13). No significant associations were demonstrated for IgA nephropathy or membranous nephropathy.ConclusionsUsing population-level data and a centralized pathology database, we observed an inverse association between socioeconomic position and the standardized incidence of lupus nephritis and ANCA-GN.

AbstractIgA nephropathy (IgAN), membranous nephropathy (MN), and lupus nephritis (LN) represent important causes of chronic kidney disease. They belong to the immune-mediated glomerulonephritis (GNs), and have distinct pathogenesis, distinct clinical courses, and variable responses to treatment. Therefore, specific diagnostic procedures are necessary for more effective patient management. Recently, a role for oxidative stress has been proposed in various renal disorders. Thus, molecules related to oxidative stress, such as 2-Cys-peroxiredoxins (PRDXs), may represent plausible candidates for biomarkers in renal pathologies. The aim of this study was to assess whether there are differences between individual GNs and healthy controls in the context of PRDXs serum concentration. We enrolled 108 patients with biopsy-proven IgAN (47), MN (26), LN (35) and 30 healthy age- and sex-matched controls. The serum concentrations of PRDX 1–5 were measured with ELISA assays and correlated with demographic and clinical data. The PRDXs’ concentration varied depending on the GN type. We also observed an association of PRDXs with lower estimated glomerular filtration rates, complement, hemoglobin, and body mass index. Our study indicates that individual PRDX can play roles in pathophysiology of selected GNs and that their serum concentrations may become useful as a new supplementary diagnostic markers in IgAN, MN as well as LN. The results of this study open a new avenue for prospective research on PRDXs in renal diseases.

Abstract Background and Aims The largest data on the epidemiology of primary glomerular diseases (PGD) are obtained from the databases of countries or centers. Here, we presented the extended results of the Primary Glomerular Diseases Study of the Turkish Society of Nephrology Glomerular Diseases (TSN-GOLD)Working Group. Method The data of patients who underwent renal biopsy and diagnosed as primary glomerular disease were recorded in the database prepared for the study. Between May 2009 and May 2019, a total of 4399 patients from 47 centers were evaluated. Basal data of 3875 patients were analyzed after exclusion of those lacking light microscopy and immunofluorescence findings. Results The mean age was 41.5 ± 14.9 years. Of the patients, 1690 were female (43.6%) and 2180 (56.3%) were male. Nephrotic syndrome was the most common biopsy indication (51.7%). This was followed by asymptomatic urinary abnormalities (18.3%) and nephritic syndrome (17.8%). The most common PGH was IgA nephropathy (25.7%), followed by membranous nephropathy (25.6%) and FSGS (21.9%). The mean total number of glomeruli per biopsy was 17 ± 10. Mean baseline systolic blood pressure was 130 ± 20 mmHg and diastolic blood pressure was 81 ± 12 mmHg. Median proteinuria was 3300 (IQR: 1467-6307) mg / day, mean serum creatinine, estimated GFR and albumin values were 1.4 ± 1.5 mg / dl, 80.7 ± 39.1 ml / min and 3.2 ± 0.9 g / dl, respectively. Conclusion In Turkey, the incidence of IgA nephropathy patients have become more common than membranous nephropathy among PGD patients diagnosed with renal biopsy.

Abstract Background and Aims Glomerulonephritis (GN) is a common cause of End-stage renal disease (ESRD) in Asia and around the world. Most studies from renal registries have focused on the prevalence or clinical characteristics of patients with GN. Only a few registry-based data have focused on mortality and ESRD risks of different types of GN. There is limited data from low to middle income countries or from Southeast Asia. The objectives of this study were to evaluate the mortality and ESRD rates among patients with different types of GN referred for a kidney biopsy at a Thai tertiary care hospital. Method In this retrospective study, the data of patients (n=1,025) referred for a kidney biopsy at Ramathibodi Hospital from 1 January 2011 to 31 December 2017 were reviewed. Patients were classified in to 11 different types of GN. Patient death and cause of death data was obtained from National Census office. ESRD data was obtained from the Thailand Nephrology Society ESRD registry which includes all patients on renal replacement therapies for greater than 3 months. Results Patients with inadequate specimen (n=66) or non-glomerular diseases (n=95) were excluded. Data from 864 patients with GN was analyzed. The age at kidney biopsy was 43.9 ± 16.8 years, median eGFR (CKD-EPI) was 42 (IQR 13-83) mL/min/1.73m2. The male:female ratio was 0.6. The prevalence of GN were: Lupus nephritis (26.8%), IgA nephropathy (18.2%), focal segmental glomerulosclerosis (FSGS 12.6 %), membranous nephropathy (11.9 %), diabetic nephropathy (10.8%), minimal change disease (9.7%), hypertensive nephrosclerosis (4.3%), pauci-immune complex glomerulonephritis (2.3%), membranoproliferative glomerulonephritis (MPGN 1.6%) and multiple myeloma (1.4%) Median time follow up was 42 (IQR 23-62) months. Overall mortality was 13 %. Lupus nephritis accounted for highest proportion of all deaths (25%), followed by diabetic nephropathy (19.1%), FSGS (9%). Listed causes of deaths were: sepsis 22% and chronic kidney disease 8%. Mortality rates by disease were: multiple myeloma (50%), diabetic nephropathy (28.7%), MPGN (21.4%), pauci-immune complex GN (20%), hypertensive nephrosclerosis (15.8%), lupus nephritis (14.6%), membranous nephropathy (8.7%), FSGS (8.2%), minimal change disease (5.8%), IgA nephropathy (4.4%) The incidence of ESRD was 14 %. LN accounted for the highest proportion (29%) of all ESRD, followed by IgA nephropathy (14%), and membranous nephropathy (13%). The rates of ESRD by disease were: multiple myeloma (33.3%), lupus nephritis (15%), membranous nephropathy (14.5%), minimal change disease (14.3%), MPGN (14.2%), IgA nephropathy (10.1%), FSGS (10.1%), diabetic nephropathy (7.4%), pauci-immune complex glomerulonephritis (5%), hypertensive nephroclerosis (2.6%). Conclusion Lupus nephritis is the most common GN and accounted for the highest proportion of all deaths and ESRD in this Thai cohort. IgA nephropathy is the most common primary GN and an important cause of ESRD, but the mortality rate is low compared to other GN. Membranous nephropathy has comparable prevalence to FSGS, but is a more important contributor to ESRD. Diabetic nephropathy has higher rate of mortality than ESRD. Multiple myleloma has the highest rate of both death and ESRD.

Lupus Glomerulonephritis

Mycophenolate mofetil (MMF) initially found widespread use in the immunoprophylaxis of rejection in organ transplantation. It has subsequently been used in lupus glomerulonephritis, where early studies have shown it to be effective in induction and maintenance therapy. The randomized studies have mostly studied small groups of patients and their conclusions do need to be confirmed in larger studies. MMF has also been used in small numbers of patients in a variety of nonlupus glomerulopathies, which have different underlying immunopathology as well as clinical course, including IgA nephropathy, membranous nephropathy, focal segmental glomerulosclerosis, membranoproliferative glomerulonephritis, hepatitis-C-associated glomerulonephritis and even Goodpasture's syndrome. In this article, we discuss its use in such nonlupus glomerular diseases.

After the exclusion of patients without light microscopy and immunofluorescence microscopy findings, a total of 3875 patients were included in the study. Results The mean age was 41.5 ± 14.9 years. 1690 patients were female (43.6%) and 2185 (56.3%) were male. Nephrotic syndrome was the most common biopsy indication (51.7%). This was followed by asymptomatic urinary abnormalities (18.3%) and nephritic syndrome (17.8%). The most common PGD was IgA nephropathy (25.7%) followed by membranous nephropathy (25.6%) and focal segmental glomerulosclerosis (21.9%). The mean total number of glomeruli per biopsy was 17 ± 10. The mean baseline systolic blood pressure was 130 ± 20 mmHg and diastolic blood pressure was 81 ± 12 mmHg. The median proteinuria, serum creatinine, estimated GFR, and mean albumin values were 3300 (IQR: 1467–6307) mg/day, 1.0 (IQR: 0.7–1.6) mg/dL, 82.9 (IQR: 47.0–113.0) mL/min and 3.2 ± 0.9 g/dL, respectively. Conclusions The distribution of PGDs in Turkey has become similar to that in other European countries. IgA nephropathy diagnosed via renal biopsy has become more prevalent compared to membranous nephropathy.

Abstract Objective To examine the association between reporting on suicides, especially deaths of celebrities by suicide, and subsequent suicides in the general population. Design Systematic review and meta-analysis. Data sources PubMed/Medline, PsychInfo, Scopus, Web of Science, Embase, and Google Scholar, searched up to September 2019. Review methods Studies were included if they compared at least one time point before and one time point after media reports on suicide; follow-up was two months or less; the outcome was death by suicide; and the media reports were about non-fictional suicides. Data from studies adopting an interrupted time series design, or single or multiple arm before and after comparisons, were reviewed. Results 31 studies were identified and analysed, and 20 studies at moderate risk of bias were included in the main analyses. The risk of suicide increased by 13% in the period after the media reported a death of a celebrity by suicide (rate ratio 1.13, 95% confidence interval 1.08 to 1.18; 14 studies; median follow-up 28 days, range 7-60 days). When the suicide method used by the celebrity was reported, there was an associated 30% increase in deaths by the same method (rate ratio 1.30, 95% confidence interval 1.18 to 1.44; 11 studies; median follow-up 28 days, range 14-60 days). For general reporting of suicide, the rate ratio was 1.002 (0.997 to 1.008; five studies; median follow-up 1 day, range 1-8 days) for a one article increase in the number of reports on suicide. Heterogeneity was large and partially explained by celebrity and methodological factors. Enhanced funnel plots suggested some publication bias in the literature. Conclusions Reporting of deaths of celebrities by suicide appears to have made a meaningful impact on total suicides in the general population. The effect was larger for increases by the same method as used by the celebrity. General reporting of suicide did not appear to be associated with suicide although associations for certain types of reporting cannot be excluded. The best available intervention at the population level to deal with the harmful effects of media reports is guidelines for responsible reporting. These guidelines should be more widely implemented and promoted, especially when reporting on deaths of celebrities by suicide. Systematic review registration PROSPERO CRD42019086559.

Introduction: Mucosal derived galactose deficient IgA is central to the pathogenesis of primary IgA nephropathy. Recent reports suggest similar pathogenesis in Henoch Schonlein purpura and secondary IgA nephropathy. Its role in other IgA containing glomerular diseases is still under investigation. It can be detected in glomeruli with the recently described antibody, KM55. We aimed to evaluate the role of KM55 by immunostaining a wide spectrum of IgA containing glomerular diseases. Methods: After standardization and co localization in a case of IgA nephropathy, a spectrum of 60 cases including IgA nephropathy, Henoch Schonlein purpura, chronic liver disease related IgA nephropathy, other secondary IgA Nephropathy, IgA dominant/co dominant membranoproliferative glomerulonephritis and lupus nephritis were subjected to immunofluorescence with KM55. KM55 was used to resolve diagnostic dilemma in cases of IgA deposition with confounding histology. Results: The group of primary IgA Nephropathy (17 cases), Henoch Schonlein purpura (4 cases) and secondary IgA nephropathy (19 cases) including chronic liver disease showed 2 -3+ granular staining with KM55 suggesting mucosal derived IgA. In contrast, cases of IgA dominant/co dominant membranoproliferative glomerulonephritis (8 cases) and lupus nephritis (12 cases) were negative for KM55, suggesting systemic derivation of IgA. In cases of IgA deposition with confounding histology such as membranoproliferative or diffuse endocapillary proliferative pattern, KM55 helped to resolve the diagnosis. Discussion/Conclusion: This cross-sectional study concludes that KM55 is useful in the evaluation of IgA containing glomerular diseases from a pathogenetic perspective, and is a practical tool in resolving differential diagnosis in cases with overlapping histopathologic features.
