Abstract
IgA nephropathy (IgAN) is associated with a risk for posttransplant recurrence. Data are limited regarding graft loss attributable to recurrence of IgAN among pediatric and young adult kidney transplant (KT) recipients. This was a retrospective cohort study of patients aged 0 to 25 years from the Scientific Registry of Transplant Recipients who received a primary KT for IgAN. Patients with history of KT attributable to renal dysplasia were comparators. Outcomes included the incidence of graft loss attributable to IgAN recurrence, association with donor type, and posttransplant corticosteroid use. In total, 5475 transplant recipients were included, with 1915 patients with IgAN and 3560 patients with renal dysplasia. In a multivariable Cox proportional hazards model, IgAN was associated with higher risk of graft loss (adjusted hazard ratio [aHR], 1.35; 95% CI, 1.21-1.50; P < .001) compared with dysplasia. Graft loss was attributed to recurrent disease in 5.4% of patients with IgAN. In a multivariable competing risks analysis, patients with IgAN receiving a parental living-donor kidney were more likely to report graft loss from recurrent disease compared with patients with a nonparental living donor (aHR, 0.52; 95% CI, 0.31-0.91; P = .02). Posttransplant prednisone use was not associated with improved graft survival (P = .2). These data challenge existing paradigms in posttransplant management of patients with IgAN.

Abstract
BACKGROUND The modified Oxford classification mesangial and endocapillary hypercellularity, segmental sclerosis, interstitial fibrosis/tubular atrophy, and the presence of crescents (MEST-C) of immunoglobulin A nephropathy (IgAN) was recently shown to be a predictor of graft failure in Asians with recurrent IgAN. We aimed to validate these findings in a cohort from North American centers participating in the Banff Recurrent Glomerulopathies Working Group. METHODS We examined 171 transplant recipients with end-stage kidney disease because of IgAN; 100 of them with biopsy-proven recurrent IgAN (57 of them had complete MEST-C scores) and 71 with no recurrence. RESULTS IgAN recurrence, which was associated with younger age at transplantation ( P = 0.012), strongly increased the risk of death-censored graft failure (adjusted hazard ratio, 5.10 [95% confidence interval (CI), 2.26-11.51]; P < 0.001). Higher MEST-C score sum was associated with death-censored graft failure (adjusted hazard ratio, 8.57 [95% CI, 1.23-59.85; P = 0.03] and 61.32 [95% CI, 4.82-779.89; P = 0.002] for score sums 2-3 and 4-5 versus 0, respectively), and so were the single components endocapillary hypercellularity, interstitial fibrosis/tubular atrophy, and crescents ( P < 0.05 each). Overall, most of the pooled adjusted hazard ratio estimates associated with each MEST-C component were consistent with those from the Asian cohort (heterogeneity I2 close to 0%, and P > 0.05). CONCLUSIONS Our findings may validate the prognostic usefulness of the Oxford classification for recurrent IgAN and support the inclusion of the MEST-C score in allograft biopsies diagnostic reports.

Clinical and Pathological Significance of Mesangial C1q Deposition in Kidney Transplant Recipients with Recurrent IgA Nephropathy and Patients with Native IgA Nephropathy. Nephron Clin Pract 2023; 147 Suppl 1:80-88.

Abstract
INTRODUCTION In kidney transplant recipients (KTRs) whose primary disease is IgA nephropathy (IgAN), IgAN recurrence occurs in approximately half of patients by 5 years postoperatively and is associated with graft survival. Although the alternative and lectin pathways are important in the primary pathogenesis of IgAN, the significance of mesangial C1q deposition, which triggers the classical pathway, is unknown. We investigated the clinicopathological significance of mesangial C1q deposition in both recurrent IgAN in KTRs and native IgAN. METHODS Between 2000 and 2021, we conducted a 1:2 matched case-control study of 18 KTRs diagnosed with recurrent IgAN, with a group of native IgAN patients as the control. We evaluated the rate and presence/absence of mesangial C1q deposition in terms of pathological findings and kidney outcomes in each group. RESULTS The rate of mesangial C1q deposition was significantly higher in the recurrent IgAN patients in KTRs than in native IgAN patients (11/18 [61.1%] vs. 5/36 [13.9%], p = 0.001). In the former group, the incidence of glomerular crescents was relatively higher in C1q-positive patients. There was no significant difference in the annual rate of estimated glomerular filtration rate decline between C1q-positive and C1q-negative patients in either group. CONCLUSION Mesangial C1q deposition was more frequent in KTRs with recurrent IgAN than in patients with native IgAN, but we found no difference in kidney outcomes with respect to mesangial C1q deposition. Further large-scale investigations of the importance of mesangial C1q deposition are needed in both KTRs with recurrent IgAN and patients with native IgAN.

CLINICOECONOMICS AND OUTCOMES RESEARCH 2023; 15:213-226. [PMID: 37020570 PMCID: PMC10067365 DOI: 10.2147/ceor.s389456] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Accepted: 03/15/2023] [Indexed: 03/30/2023] Open
Abstract
Purpose To estimate the cost-effectiveness of Nefecon in addition to the best supportive care (BSC) vs BSC in a hypothetical cohort of commercially insured adult patients with primary immunoglobulin A nephropathy (IgAN) from a United States (US) societal perspective. Methods A lifetime horizon, semi-Markov model was developed that consisted of nine health states: chronic kidney disease (CKD) stage 1, 2, 3a, 3b, 4, end-stage renal disease (ESRD) with dialysis, ESRD without dialysis, post-kidney transplant, and death. Health state occupancy was estimated from individual patient-level data from the Phase 3 randomized controlled trial NefIgArd Part A (NCT03643965). Additional scenarios evaluated the impact of varying the time horizon, discounting, costs included, rounds of treatment, and the method used to calculate transition probabilities. Results In the deterministic base case analysis over a lifetime horizon, Nefecon plus BSC (hereafter Nefecon) had an incremental cost of $3,810 vs BSC. Nefecon resulted in a mean survival gain of 0.247 quality-adjusted life years (QALYs), 0.195 life years (LYs), and 0.244 equal value life years (evLYs) vs BSC alone - this resulted in incremental cost-effectiveness ratios (ICERs) of $15,428 per QALY, $19,502 per LY, and $15,611 per evLY gained. Probabilistic sensitivity analyses estimated that with willingness to pay thresholds of $100,000, $150,000, and $250,000 per QALY gained, Nefecon would be cost-effective over BSC in 66.70%, 75.02%, and 86.82% of cases, respectively. In the scenario analysis, Nefecon remained cost-effective with 4 rounds of treatment. Conclusion Nefecon was associated with LY and QALY gains vs BSC, with an incremental cost of $3,810. Based on these values, with a willingness to pay threshold of $100,000 per QALY gained, Nefecon was found to be a cost-effective treatment for US adults with primary IgAN.

Abstract
BACKGROUND Recurrent glomerulonephritis (GN) is a common cause of allograft loss in kidney transplantation (KT), the most frequent of which is immunoglobulin A (IgA) nephropathy (IgAN). Galactose-deficient IgA1 (Gd-IgA1) plays a major role in the pathophysiology of IgAN, but the association between Gd-IgA1 and recurrent IgAN in kidney transplant recipients (KTRs) is uncertain. We aimed to evaluate the efficacy of Gd-IgA1 for prediction of recurrent IgAN and graft and patient survival according to Gd-IgA1 level. METHODS We enrolled 27 KTRs who underwent allograft biopsy between 2009 and 2016 and measured the serum Gd-IgA1 level of each KTR. We divided the patients into two groups: nonrecurrent IgAN (patients with IgAN prior to KT who were not diagnosed with recurrent IgAN) and recurrent IgAN (patients with IgAN prior to KT who were diagnosed with recurrent IgAN). RESULTS The mean serum Gd-IgA1 level was significantly higher in the recurrent IgAN group than in the nonrecurrent IgAN group (6,419 ± 3,675 ng/mL vs. 3,381 ± 2,844 ng/mL, p = 0.02). The cutoff value of serum Gd-IgA1 in receiver operating characteristic curve analysis was 4,338 ng/mL (area under the curve, 0.76; 95% confidence interval [CI], 0.57-0.95, p = 0.02). Serum Gd-IgA1 level was an independent factor for recurrent IgAN (odds ratio, 17.60; 95% CI, 1.33-233.03, p = 0.03). There was no significant difference in graft or patient survival between the two groups. CONCLUSION Serum Gd-IgA1 can be used as a diagnostic biomarker for recurrent IgAN in KT.

Abstract
The 2020 Kidney Disease: Improving Global Outcomes (KDIGO) Clinical Practice Guideline on the Evaluation and Management of Candidates for Kidney Transplantation is intended to assist health care professionals worldwide who evaluate and manage potential candidates for deceased or living donor kidney transplantation. This guideline addresses general candidacy issues such as access to transplantation, patient demographic and health status factors, and immunological and psychosocial assessment. The roles of various risk factors and comorbid conditions governing an individual's suitability for transplantation such as adherence, tobacco use, diabetes, obesity, perioperative issues, causes of kidney failure, infections, malignancy, pulmonary disease, cardiac and peripheral arterial disease, neurologic disease, gastrointestinal and liver disease, hematologic disease, and bone and mineral disorder are also addressed. This guideline provides recommendations for evaluation of individual aspects of a candidate's profile such that each risk factor and comorbidity are considered separately. The goal is to assist the clinical team to assimilate all data relevant to an individual, consider this within their local health context, and make an overall judgment on candidacy for transplantation. The guideline development process followed the Grades of Recommendation Assessment, Development, and Evaluation (GRADE) approach. Guideline recommendations are primarily based on systematic reviews of relevant studies and our assessment of the quality of that evidence, and the strengths of recommendations are provided. Limitations of the evidence are discussed with differences from previous guidelines noted and suggestions for future research are also provided.

Abstract
PURPOSE OF REVIEW With improving short-term kidney transplant outcomes, recurrent glomerular disease is being increasingly recognized as an important cause of chronic allograft failure. Further understanding of the risks and pathogenesis of recurrent glomerular disease enable informed transplant decisions, along with the development of preventive and treatment strategies. RECENT FINDINGS Multiple observational studies have highlighted differences in rates and outcomes for various recurrent glomerular diseases, although these rates have not markedly improved over the last decade. Emerging evidence supports use of rituximab to treat recurrent primary membranous nephropathy and possibly focal segmental glomerulosclerosis (FSGS), whereas eculizumab is effective in glomerular diseases associated with complement dysregulation [C3 glomerulopathy (C3G) and atypical hemolytic uremic syndrome (aHUS)]. SUMMARY Despite the potential for recurrence in the allograft, transplant remains the optimal therapy for patients with advanced chronic kidney disease (CKD) secondary to primary glomerular disease. Biomarkers and therapeutic options necessitate accurate pretransplant diagnoses with opportunities for improved surveillance and treatment of recurrent glomerular disease posttransplant.

Abstract
In view of the availability of new immunosuppression strategies, the recurrence of allograft glomerulonephritis (GN) are reported to be increasing with time post transplantation. Recent advances in understanding the pathogenesis of the GN recurrent disease provided a better chance to develop new strategies to deal with the GN recurrence. Recurrent GN diseases manifest with a variable course, stubborn behavior, and poor response to therapy. Some types of GN lead to rapid decline of kidney function resulting in a frustrating return to maintenance dialysis. This subgroup of aggressive diseases actually requires intensive efforts to ascertain their pathogenesis so that strategy could be implemented for better allograft survival. Epidemiology of native glomerulonephritis as the cause of end-stage renal failure and subsequent recurrence of individual glomerulonephritis after renal transplantation was evaluated using data from various registries, and pathogenesis of individual glomerulonephritis is discussed. The following review is aimed to define current protocols of the recurrent primary glomerulonephritis therapy.

Abstract
AIM Recurrent IgA nephropathy (IgAN) is a common recurrent glomerular disease after kidney transplantation. Recurrent IgAN, in particular, with crescent formation or endocapillary proliferation might result in kidney allograft loss. However, the current treatment options of recurrent IgAN are conflicting. METHODS We have reported three kidney-transplanted recipients with biopsy-proven recurrent IgAN treated with four consecutive months of rituximab at the dose of 375 mg/1.73m2 without corticosteroids. RESULTS At median follow-up 20 months following rituximab administration, all three recipients demonstrated decrease in proteinuria severity, slow disease progression with a well-tolerated condition. This therapeutic effect is most probably mediated by the B cell depletion. CONCLUSION Our three case reports suggest that the disease severity of recurrent IgAN with endocapillary proliferation regardless of crescent formation can be minimized by the four doses of monthly rituximab regimen.

Abstract
Recurrent glomerulonephritis (GN) is an important cause of kidney allograft failure, particularly in younger recipients. Approximately 15% of death-censored graft failures are due to recurrent GN, but this incidence is likely an underestimation of the magnitude of the problem. Overall, 18% to 22% of kidney allografts are lost due to GN, either recurrent or presumed de novo. The impact of recurrent GN on allograft survival was recognized from the earliest times in kidney transplantation. However, progress in this area has been slow, and our understanding of GN recurrence remains limited, in large part due to incomplete understanding of the pathogenesis of these diseases. This review focuses on recent advances in our general understanding of the pathophysiology of primary GN, the risk of recurrence in the allograft, and the consequences for kidney graft survival. We focus specifically on the most common forms of primary GN, including focal segmental glomerulosclerosis, membranous nephropathy, membranoproliferative glomerulonephritis, and IgA nephropathy. New understanding of the pathogenesis of these diseases has had direct clinical implications for transplantation, allowing better identification of candidates at high risk of recurrence and earlier diagnoses, and it is expected to lead to significance improvements in the therapy and perhaps even prevention of GN recurrence. More than ever, it is essential to fully characterize GN before transplantation as this information will direct our management posttransplantation. Further, the relative rarity of recurrent GN dictates the need for multicenter studies in order to evaluate, test, and validate recent advances and therapies.

Abstract
AIM Recurrence of immunoglobulin A (IgA) nephropathy (IgAN) after renal transplantation is important as a cause of graft failure under improving rejection control. However, no specific therapy for recurrent IgAN is currently available. In this study, we evaluated the histological efficacy of tonsillectomy for allograft IgAN. METHODS Fifteen kidney recipients (male 9, female 6, mean age 40.9 ± 9.3 years), who received a diagnosis of IgA nephropathy by allograft biopsy, were enrolled in this study. Tonsillectomy was performed 44.1 ± 27.1 months after the kidney transplantation. All patients underwent a repeat graft biopsy at 23.8 ± 15.8 months after tonsillectomy. RESULTS Six patients had microhematuria before tonsillectomy. At 12 months after treatment, the microhematuria disappeared in five of these patients and one patient had mild hematuria. Three patients had severe proteinuria (more than 1.0 g/gCr) before tonsillectomy and improved after treatment. On histological analysis, four patients had acute lesions including cellular or fibrocellular crescents. The acute lesions disappeared after these treatments in all patients. Eleven patients had chronic lesions including global sclerosis, segmental sclerosis and fibrous crescents. The chronic lesion was ameliorated in six patients, unchanged in three and deteriorated in two patients. CONCLUSIONS Tonsillectomy improves not only clinical findings but also ameliorates histological damage caused by recurrent IgAN after kidney transplantation. Tonsillectomy is a novel and effective treatment for recurrent IgAN.

Abstract
A 27-year-old man was diagnosed with IgA nephropathy and Crohn's disease. He had been diagnosed with proteinuria and hematuria since he was 20 years old. Diarrhea had been a continuing problem during the past 5 months. Neither corticosteroid therapy nor tonsillectomy was performed. Hemodialysis was required at age of 30, while the symptoms of Crohn's disease were ameliorated by an elemental diet. He received a renal transplant from his mother 4 months after starting dialysis therapy. The initial immunosuppression therapy consisted of methylprednisolone, mycofenolate mofetil, cyclosporine, and basiliximab. Eight months after transplantation, proteinuria and hematuria appeared and serum creatinine was 1.4 mg/dL. Relapse of IgA nephropathy was confirmed by the one-year protocol biopsy. He had suffered from tonsillitis at 32 months after the transplantation. Urinary protein increased to 3 g/day and serum creatinine was elevated to 2.04 mg/dL. Renal biopsy was performed 2 weeks after the urinary findings were aggravated. The cellular crescents constituted 36 % of the glomeruli. The findings of rejection were not confirmed in both biopsies. Tonsillectomy was performed thereafter. No additional immunosuppressive therapy was added. Proteinuria and hematuria disappeared at 4 and 20 months, respectively, after tonsillectomy, even when the symptoms of Crohn's disease worsened 69 months and 89 months after transplantation. A renal biopsy was performed 101 months after transplantation. Although IgA in the mesangium area was confirmed by immunohistochemical staining, no active lesion was seen. Tonsillectomy along with immunosuppressants for the graft might be an effective treatment for some patients with active recurrent IgA nephropathy.

Abstract
Since 2007, we have performed tonsillectomies for patients with recurrent immunoglobulin A nephropathy (IgAN) after kidney transplantation. Seven patients with primary IgAN showed biopsy-proven recurrent IgAN after living-donor kidney transplantation. They had persistent proteinuria or hematuria for an average of 40.3 months, and tonsillectomy was performed, on average, 75.6 months after kidney transplantation. In six patients with observation periods of more than one year, good remission of urinary findings was observed after tonsillectomy. We classified the seven patients into three types of renal injury based on histological findings: severe, moderate, and mild. Two patients classified with severe renal injury at the time of tonsillectomy had other problems, such as refractory hypertension and bilateral sinusitis. They followed a rapidly progressive clinical course. One case already had moderate histological renal injury. He demonstrated prompt amelioration of urinary findings after tonsillectomy but immediate deviation from remission of proteinuria and hematuria. In the four cases presenting mild renal injury at tonsillectomy, the improved urinary findings and serum creatinine value after tonsillectomy have persisted. In conclusion, tonsillectomy may be a favorable treatment for cases of mild-grade IgAN. However, other treatments such as antihypertensive agents and diet therapy may be necessary in other grades.

Abstract
Almost all forms of primary as well as secondary glomerulonephritides may recur after renal transplantation. Recurrence of the original disease is now the third most common cause of late allograft loss. Nevertheless, in most cases it is difficult to assess the true impact of primary disease recurrence in the allograft; histological recurrence with mild features does not necessarily implicate clinically severe disease. Moreover it is often difficult to distinguish recurrent from de novo disease as in membranous glomerulopathy. Because recurrence occurs late, histological lesions of recurrent glomerulonephritis may be unmasked by chronic damage from other causes such as chronic rejection. Beside the difficulties to interpret renal histology due to the variety of allograft lesions, there are no well-established options to prevent clinically severe disease recurrence nor the therapeutic approaches to the problem. The purpose of this review was mainly to underline that almost all primary and secondary glomerulonephritides represent a contraindication to transplantation. For the majority of patients with end-stage renal disease due to glomerulonephritis, transplantation still represents the treatment of choice.

Abstract
Recurrence of glomerulonephritis following renal transplantation is considered an important cause of allograft failure. The incidence of recurrence of glomerulonephritis varies widely depending on the definition of recurrence (pathologic recurrence or clinicopathologic recurrence) and the original glomerular disease. Moreover the impact of recurrence of glomerular disease on allograft outcome varies widely between different forms of glomerulonephritis. Whereas IgA nephritis recurs in up to one third of transplanted patients, this is not associated with adverse effects on graft survival. In contrast, recurrent focal segmental glomerulosclerosis and membranoproliferative glomerulopathy have an unfavorable prognosis. Overall, long-term graft survival in patients transplanted for glomerulonephritis is comparable to survival in patients with other causes of ESRD. In recent years, several mechanisms for recurrent disease after transplantation (e.g. PLA2R antibodies in membranous nephropathy and suPAR in FSGS) have been identified, and these findings have helped to elucidate the pathogenesis of glomerular diseases. Although renal transplantation is the treatment of choice for end-stage renal disease as a consequence of glomerulonephritis, further studies are required to develop optimal strategies to prevent, diagnose and treat recurrent glomerular diseases.

Abstract
All forms of primary GN may recur after kidney transplantation and potentially jeopardize the survival of the graft. IgA nephritis (IgAN) may recur in approximately one third of patients, more frequently in younger patients and in those with a rapid progression of the original disease. However, with the exception of few patients with rapid progression, there is no evidence that recurrence of IgAN has a deleterious effect on graft survival at least up to 10 years. Recurrence of focal segmental glomerulosclerosis (FSGS) is often associated with nephrotic proteinuria and is more frequent in children, in patients with rapid progression of the original disease, and in those who lost a previous transplant from recurrence. The natural course of recurrent FSGS is usually unfavorable. Early and intensive plasmapheresis may obtain complete or partial response in several patients. Good results have also been reported with rituximab. Idiopathic membranous nephropathy (IMN) may recur in 30% to 40% of patients. The graft survival in patients with IMN is not different than that of patients with other renal diseases. Good results with rituximab have been reported. Membranoproliferative GN (MPGN) may recur in 27% to 65% of patients. The recurrence is more frequent and the prognosis is more severe in type II MPGN. Although recurrent GN is relatively frequent and may worsen the outcome of renal allografts in some patients, its effect is diluted by several other risk-factors that may have a greater effect than recurrent GN on the long-term graft survival.

Abstract
BACKGROUND Few studies have been conducted to determine the efficacy of tonsillectomy in suppressing IgA nephropathy recurring after the kidney transplantation. MATERIALS AND METHODS Of the 405 kidney recipients who received allograft transplants at our institution between 1998 and 2005, 63 (63 of 405, 16%) were diagnosed as having recurrence of IgA nephropathy in the kidney graft. Among the 63 patients, our subjects in this study were 28 patients who were confirmed to have recurrence of IgA nephropathy by histopathological examination, and who had persistent urinary protein excretion levels of more than 300 mg/day despite medical treatments. Sixteen patients (group 1) underwent tonsillectomy alone, whereas the remaining 12 patients (group 2) did not receive tonsillectomy. The degree of proteinuria, kidney graft function, and blood pressure were analyzed retrospectively in the two patient groups. RESULTS The urinary protein excretion decreased dramatically after the tonsillectomy in all of the 16 patients of group 1 (880+/-630 mg/day to 280+/-220 mg/day, P<0.01) but none of group 2. The reduction in urinary protein excretion after tonsillectomy was especially marked in the patients with mild mesangial changes, such as minor glomerular abnormalities, when compared with that in patients with severe mesangial changes, such as diffuse proliferative glomerular abnormalities (mean percent decrease in the urinary protein excretion rate at 12 months after tonsillectomy; 31% minor glomerular abnormalities vs. 62% diffuse proliferative glomerular abnormalities, P<0.01). CONCLUSION These results suggest that in patients receiving oral immunosuppressive therapy for recurrence of IgA nephropathy after the kidney transplantation, reduction of the urinary protein excretion can be expected with tonsillectomy alone, without accompanying pulsed steroid therapy.
