Abstract
BACKGROUND Haemopoietic stem cell transplant (HSCT) is a well-established treatment option for many haematologic immunologic and oncologic diseases, allowing the safe administration of high-dose chemotherapy. Increased risk of acute renal injury is associated with HSCT; however, the risk of chronic kidney injury in autologous HSCT remains unclear. AIMS This cohort study investigates the incidence of chronic renal injury and its predisposing factors in a single-centre population of 139 patients who underwent autologous HSCT. METHODS Estimated glomerular filtration rate (eGFR) was measured at baseline and at 3, 6, 12 and 24 months following autologous stem cell reinfusion and used as a marker of renal dysfunction. RESULTS A significant reduction in mean eGFR of patients was observed from baseline (80.62 ± 2.97 mL/min) to 24 months (71.54 ± 4.14 mL/min), independent of primary diagnosis (P = 0.0019). At baseline, 12% of the cohort had stage 3 or worse chronic renal injury and this increased to 38% by 24 months. By univariate analysis, age at baseline greater than the mean of 58 years and the occurrence of acute kidney injury during the peritransplant period emerged as predictive factors for the development of chronic kidney disease at 24 months. CONCLUSIONS The current results indicate there is an increased incidence of chronic renal injury in patients who have undergone autologous peripheral blood haemopoietic stem cell transplantation therapy and this injury is potentiated by the autologous stem cell transplant procedure.

Abstract
A 67-year-old woman who had undergone bone marrow transplantation 2 years previously for acute myeloid leukemia (AML) developed complications of chronic graft-versus-host disease (cGVHD). She thereafter also developed nephrotic syndrome, and membranous nephropathy (MN) was diagnosed by a renal biopsy. Although the causative antigens of the MN were not detected, immunofluorescence staining showed codominant deposition of immunoglobulins G2 and G3, a finding indicating secondary MN, thereby suggesting an association between MN and cGVHD. Rituximab treatment was initiated, and her nephrotic syndrome gradually improved without relapse of AML. Our present case suggests that rituximab is a safe and effective therapeutic option for cGVHD-associated MN.

Abstract
Whether autologous hematopoietic stem cell transplantation is free from graft-versus-host disease is controversial. Alawam et al. (2021. J. Exp. Med.https://doi.org/10.1084/jem.20211239) now demonstrate that prolonged damage in thymic medullary epithelial cells causes the failure in self-tolerance in newly generated T cells and provokes post-transplant autoimmunity.

Abstract
Membranous nephropathy (MN) is a common cause of proteinuria and nephrotic syndrome all over the world. It can be subdivided into primary and secondary forms. Primary form is an autoimmune disease clinically characterized by nephrotic syndrome and slow progression. It accounts for ~70% cases of MN. In the remaining cases MN may be secondary to well-defined causes, including infections, drugs, cancer, or autoimmune diseases, such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), urticarial vasculitis, sarcoidosis, thyroiditis, Sjogren syndrome, systemic sclerosis, or ankylosing spondylitis. The clinical presentation is similar in primary and secondary MN. However, the outcome may be different, being often related to that of the original disease in secondary MN. Also, the treatment may be different, being targeted to the etiologic cause in secondary MN. Thus, the differential diagnosis between primary and secondary MN is critical and should be based not only on history and clinical features of the patient but also on immunofluorescence and electron microscopy analysis of renal biopsy as well as on the research of circulating antibodies. The identification of the pathologic events underlying a secondary MN is of paramount importance, since the eradication of the etiologic factors may be followed by remission or definitive cure of MN. In this review we report the main diseases and drugs responsible of secondary MN, the outcome and the pathogenesis of renal disease in different settings and the possible treatments.

Abstract
Background Membranous nephropathy (MN), the leading cause of nephrotic syndrome in adults, is characterized by the deposition of subepithelial immune deposits. Most of the cases are primary, while only approximately 25% of the cases are secondary to some known diseases. Recently, MN has been considered to be a possible presentation of chronic graft-versus-host disease (GVHD) of the kidney in allogeneic hematopoietic stem cell transplantation (HSCT) patients. In autologous HSCT populations, there have been scarce reports of associated MN, as a result of immune dysregulation leading to systemic autoimmunity and miming chronic GVHD. Case presentation We report an exceptional case of MN associated to an acute renal failure occurring within days following an autologous HSCT indicated by multiple myeloma. There was no evidence of GVHD or myeloma relapse. A complete remission of nephrotic syndrome with normalization of renal function were rapidly obtained by corticosteroid therapy. Conclusion This is the first published case of acute renal failure due to MN occurring in the acute phase of an autologous HSCT. These findings support the antibodymediated autoimmune glomerular disease.

Membranous Nephropathy and Anti-Podocytes Antibodies: Implications for the Diagnostic Workup and Disease Management. BIOMED RESEARCH INTERNATIONAL 2018; 2018:6281054.

Abstract
The discovery of circulating antibodies specific for native podocyte antigens has transformed the diagnostic workup and greatly improved management of idiopathic membranous nephropathy (iMN). In addition, their identification has clearly characterized iMN as a largely autoimmune disorder. Anti-PLA2R1 antibodies are detected in approximately 70% to 80% and anti-THSD7A antibodies in only 2% of adult patients with iMN. The presence of anti-THSD7A antibodies is associated with increased risk of malignancy. The assessment of PLA2R1 and THSD7A antigen expression in glomerular immune deposits has a better sensitivity than measurement of the corresponding autoantibodies. Therefore, in the presence of circulating anti-podocytes autoantibodies and/or enhanced expression of PLA2R1 and THSD7A antigens MN should be considered as primary MN (pMN). Anti-PLA2R1 or anti-THSD7A autoantibodies have been proposed as biomarkers of autoimmune disease activity and their blood levels should be regularly monitored in pMN to evaluate disease activity and predict outcomes. We propose a revised clinical workup flow for patients with MN that recommends assessment of kidney biopsy for PLA2R1 and THSD7A antigen expression, screening for circulating anti-podocytes antibodies, and assessment for secondary causes, especially cancer, in patients with THSD7A antibodies. Persistence of anti-podocyte antibodies for 6 months or their increase in association with nephrotic proteinuria should lead to the introduction of immunosuppressive therapies. Recent data have reported the efficacy and safety of new specific therapies targeting B cells (anti-CD20 antibodies, inhibitors of proteasome) in pMN which should lead to an update of currently outdated treatment guidelines.

Abstract
Hematopoietic cell transplantation (HCT) is an increasingly used treatment for hematologic malignancies as well as for nonmalignant diseases. Kidney impairment remains an important early and late post-transplantation complication. Although numerous histopathological changes have been reported, the pathophysiology remains incompletely understood. Furthermore, correlations between clinical findings and morphological changes have not been well studied. Between 2000 and 2016, 17 recipients of allogeneic (n = 12) or autologous (n = 5) HCT underwent kidney biopsy for either proteinuria or deterioration of kidney function at our center. The most common biopsy findings were therapy-related changes with thrombotic microangiopathy (n = 5), calcineurin inhibitor toxicity (n = 4), and membranous glomerulonephritis (n = 3), representing the majority of cases in this category. In addition, kidney findings from 137 autopsies performed between 1995 and March 2017 were analyzed. The most common changes were acute kidney injury (n = 55), most likely due to the patients' premortal deteriorated state, and thrombotic microangiopathy (n = 14). Several cases demonstrated involvement by either infectious agents (n = 6) or tumors (n = 9). Distinct kidney diseases, such as glomerulonephritis, were rare (3% of cases). Uncommon and yet rarely described diagnoses for this patient cohort were IgG4-related tubulointerstitial nephritis and fibrillary nephritis. This study provides a comprehensive overview of the histomorphological findings in kidney biopsy specimens from HCT recipients. Along with treatment-related complications, one putative correlate of chronic GVHD of the kidney could be documented: membranous glomerulonephritis. In contrast, no morphological correlate of acute GVHD of the kidney was identified. Findings at the time of autopsy varied greatly, spanning a wider range than those of indication biopsies.

Abstract
Nephrotic syndrome (NS) rarely occurs in post-hematopoietic stem cell transplantation (HSCT) recipients but represents the renal manifestation of graft-versus-host disease (GVHD). Membranous nephropathy (MN) accounts for almost two thirds of post-HSCT NS and is caused by immune complex deposition. Renal thrombotic microangiopathy (TMA) without fulfillment of clinical criteria for TMA has been underreported because of reduced opportunity for histological examination. However, renal TMA has recently been reported in association with GVHD and humoral immunological reactions. Although both MN and TMA after HSCT are associated with GVHD and immunological abnormalities, these diseases are exceptionally coexistent in renal biopsy specimens. We herein describe a case of post-HSCT NS, histologically showing overlapped lesions of TMA and MN. Renal biopsy specimen after presentation of NS revealed early stage MN and TMA with evidence of chronicity. TMA was thought to have preceded MN, and renal biopsy at the phase of pre-nephrotic proteinuria might reveal earlier histological changes of isolated renal TMA. Detection of subclinical renal TMA earlier by spontaneous renal biopsy can help prevent progression of renal injury or overlapping of other renal pathologies. We also demonstrated Th2 predominant intraglomerular infiltration of lymphocytes by immunohistochemistry.

Abstract
Autoantibodies to M-type phospholipase A2 receptor (PLA2R) are specific markers of idiopathic membranous nephropathy (IMN). They can differentiate IMN from other glomerular diseases and primary from secondary forms of MN. Preliminary data suggest that anti-PLA2R antibody titer correlates with disease activity but more solid evidence is needed. To evaluate the performance of anti-PLA2R antibody for monitoring nephropathy activity, 149 anti-PLA2R antibody measurements were performed during the follow-up of 42 biopsy proven IMN consecutive patients. Patients were enrolled either at time of diagnosis (33 cases, inception cohort) or after diagnosis (9 patients, non-inception cohort). Anti-PLA2R detection was performed using the highly sensitive transfected cell-based indirect immunofluorescence (IIFT). Over the follow-up there was a linear time-trend of decreasing proteinuria (P<0.001), increasing serum albumin (P<0.001) and decreasing PLA2R antibody levels (P=0.002). There was a statistically significant association between changes in PLA2R antibody levels and the clinical course of PLA2R-positive IMN. The positive PLA2R serum antibody status was linearly associated with increasing proteinuria and decreasing serum albumin over time, compared with negative antibody status. Moreover, the strong correlation between the clinical conditions and PLA2R antibody levels allowed the prediction of prevalence distribution of patients with active disease, partial and complete remission. Over the course of the follow-up, the probability of halving proteinuria increased 6.5 times after disappearance of PLA2R antibodies. Our data suggest that the serial evaluation of anti-PLA2R antibodies could help in optimal timing and duration of the immunosuppressive therapy, reducing over(under)-treatment and associated side-effects.
