Background
IgA nephropathy (IGAN) rarely can present as a crescent and progressive form leading to end-stage renal disease (ESRD) in a short period of time. Recurrence of IGAN after kidney transplantation is frequent, and complement components such as C3, C4d, and C5 seem to be involved. We present a case of a young male patient with ESRD caused by rapidly progressive IGAN and who demonstrated rapid recurrence of crescentic IGAN after kidney donation.Case Report
In September 2014, a 28-year-old male patient was hospitalized due to IGAN with 60% of crescents. Cyclophosphamide, steroids, and plasmapheresis did not prevent ESRD. After 8 months of peritoneal dialysis, the patient received a blood group–compatible living donor kidney from his 57-year-old mother. Immunosuppression consisted of tacrolimus, mycophenolic acid, and steroids without induction therapy. Acute graft failure occurred 2 months later, and graft biopsy results revealed recurrence of crescentic IGAN. Cyclophosphamide was added to tacrolimus and steroid treatment, but graft function could not be restored despite viable kidney tissue in repeated biopsy specimens. Rescue therapy with 4 single doses of eculizumab was introduced while hemodialysis had already been initiated. After a cumulative dose of 1800 mg of eculizumab, kidney function did not recover.Conclusions
In this case, eculizumab was not effective in treating IGAN recurrence after transplantation. Therapy was started late when hemodialysis had already been initiated; an earlier start of therapy might be more effective. 相似文献2.

Three patients with negative Lewis phenotypes who displayed anti-Lewis antibodies suffered severe kidney allograft dysfunction. One woman and two men (22-44 years) received ABO compatible kidney transplants with negative donor-recipient cross-match tests. Two patients had the phenotype Le(a-b-) with anti-Le(a) and anti-Le(b) complement binding antibodies. The third patient of phenotype Le(a+b-) developed anti-Lewis(b) antibody a few months after transplantation. One patient presented recurrence of worsened graft function from the day 6 to 4 months after transplantation; despite treatment there was not full recovery. The second patient had recurrences of acute graft dysfunction at 4 and 6 months after transplantation with nephrotic range proteinuria. The third patient showed progressive graft dysfunction at 7 months after transplantation. Biopsy specimens showed histological changes of antibody-mediated rejection. In the third patient, we observed fibrinoid necrosis and thrombosis of arterioles and glomerular capillaries. Immunofluorescence studies showed immunoglobulin IgG and IgM in glomerular capillaries and C4d and C3 on endothelial cells of peritubular capillaries. Posttransplantation cross-match tests with donor lymphocytes were negative. Anti-Lewis antibodies were observed during follow-up. All patients were treated with methylprednisolone boluses. In addition, one subject received antithymocyte globulin (ATG) and 1 received plasmapheresis. Two patients had moderate renal dysfunction (creatinine levels 1.8 and 1.9 mg/dL) after 8-17 months follow-up. The third patient lost her graft at 11 months after transplantation. Lewis antibodies may injure a renal allograft. C4d deposition and failure to show donor-specific anti-HLA antibodies suggested the participation of other antibodies. 相似文献

Glomerulonephritis and hereditary angioedema: report of 2 cases 总被引:1,自引:0,他引:1
Hereditary deficiency of C1 esterase inhibitor (C1 INH) responsible for hereditary angioedema (HAE) is the most common hereditary complement deficiency. HAE has occasionally been reported in association with lupus erythematosus and with glomerulonephritis (GN). We report 2 cases of GN-associated C1 INH deficiency. Renal manifestations have been discovered respectively 6 to 17 years before onset of attacks. Kidney biopsy of the 1st patient showed diffuse proliferative GN with a rare and scattered wire loop pattern whereas the 2nd patient displayed a type I membranoproliferative GN. Chronic renal failure appeared in both cases and the 2nd patient recently received a kidney transplant. The onset of GN in patients with HAE outline the relationship between a genetic deficiency of complement components, the susceptibility to immune complex (IC) disease and the role of complement and its receptors in the elimination of IC. 相似文献

Dense deposit disease of the kidney is a rare form of chronic glomerulonephritis frequently associated with serum complement abnormalities (low C3 levels) and a circulating C3 convertase activator of the alternative pathway, the C3 nephritic factor (NF). Eleven patients with end-stage dense deposit disease underwent kidney transplantation. Of the 11, 7 had pretransplant low C3 and NF. In the posttransplant period, persisting low C3 levels were associated with persisting NF, although not quantitatively so. The original glomerular lesion recurred in the graft within 6 months in 9 of 11. Of these 9, 2 had no complement abnormalities either prior to or after transplantation. Pretransplant complement abnormalities were rapidly corrected in 4 of 7 patients whether or not recurrence of the original lesion occurred. Thus, serum complement profiles before and after transplantation are neither predictive nor indicative of recurrence. 相似文献

C3 glomerulonephritis (C3GN) results from abnormalities in the alternative pathway of complement, and it is characterized by deposition of C3 with absent or scant Ig deposition. In many patients, C3GN progresses to ESRD. The clinical features, pathology, and outcomes of patients with C3GN receiving kidney transplantation are unknown. Between 1996 and 2010, we identified 21 patients at our institution who received a kidney transplant because of ESRD from C3GN. The median age at the time of initial diagnosis of C3GN at kidney biopsy was 20.8 years. The median time from native kidney biopsy to dialysis or transplantation was 42.3 months. Of 21 patients, 14 (66.7%) patients developed recurrent C3GN in the allograft. The median time to recurrence of disease was 28 months. Graft failure occurred in 50% of patients with recurrent C3GN, with a median time of 77 months to graft failure post-transplantation. The remaining 50% of patients had functioning grafts, with a median follow-up of 73.9 months. The majority of patients had hematuria and proteinuria at time of recurrence. Three (21%) patients were positive for monoclonal gammopathy and had a faster rate of recurrence and graft loss. Kidney biopsy at the time of recurrence showed mesangial proliferative GN in eight patients and membranoproliferative GN in six patients. All allograft kidney biopsies showed bright C3 staining (2–3+), with six biopsies also showing trace/1+ staining for IgM and/or IgG. To summarize, C3GN recurs in 66.7% of patients, and one half of the patients experience graft failure caused by recurrence.C3 glomerulonephritis (C3GN) is the result of dysregulation in the alternative pathway of complement.1,2 The renal biopsy is characterized by dominant staining for complement factor C3 with minimal or no staining for Igs on immunofluorescence microscopy. Light microscopy reveals a proliferative pattern of injury with evidence of mesangial, subendothelial, and, occasionally, subepithelial deposits on electron microscopy.3,4 Clinically, the disease presents with hematuria, proteinuria, and low serum C3 levels.2 The renal outcome of patients with C3GN is not as well established. The disease seems to have a chronic, but progressive, course, with deterioration in renal function and development of ESRD in up to 50% of the patients.5 Even less well established is the course of C3GN after kidney transplantation. The aim of this study was to examine the outcome of kidney transplantation in patients with C3GN, further characterize the histology of recurrent C3GN (rC3GN), and compare the results with recurrent dense deposit disease (DDD). 相似文献

Atypical hemolytic-uremic syndrome (aHUS) is an extremely rare disease, and up to 70% of the patients have a genetic mutation in the encoding components of complement activation or anti-complement factor H autoantibodies. The risk of recurrence after kidney transplantation is 10% to 80%. Eculizumab, a monoclonal antibody that binds complement protein C5, has shown to be highly effective in patients with aHUS; however, there are only few reports on the efficacy and safety of long-term eculizumab treatment in children with recurrent aHUS. Only 3 case reports regard treatment in patients with complement factor H (CFH/CFHR1/CFHR3) hybrid gene. This report presents the efficacy and safety of long-term eculizumab treatment in a child with recurrent aHUS who has been successfully treated with eculizumab for more than 7 years. The patient presented as a 9-year-old with aHUS due to CFH/CFHR1/CFHR3 hybrid gene and received deceased donor kidney transplantation. After the transplantation, he experienced recurrence of aHUS 2 months later. Daily plasma exchanges were ineffective in the transplanted kidney; the patient became anuric and hemodialysis was needed. Eculizumab was started as therapy and led to complete remission of aHUS including restoration of diuresis. Eculizumab has been given as therapy for 7 years. The young patient is in a sustained remission without any adverse events. This patient is only the sixth patient reported with recurrent aHUS due to CFH/CFHR1/CFHR3 hybrid gene and is the patient with the longest remission of recurrent aHUS ever published. 相似文献

Hereditary complete C4 deficiency has until now been reported in 30 cases only. A disturbed clearance of immune- complexes probably predisposes these individuals to systemic lupus erythematosus, other immune- complex diseases and recurrent microbial infections. We present here a 20- year- old female with hereditary complete C4 deficiency. Renal biopsy demonstrated renal AA amyloidosis. This unique case further substantiates that deficiency of classical pathway components predisposes to the development of recurrent microbial infections and that the patients may develop AA amyloidosis. Furthermore, in clinical practice, the nephrotic syndrome occurring in a patient with hereditary complete complement C4 deficiency should lead to the suspicion of renal AA amyloidosis. 相似文献

Hereditary complete C4 deficiency (C4def) is a very rare condition that predisposes to immune complex disease and end-stage renal failure. Whether such patients should undergo renal transplantation is debated. The clinical outcome of five transplantations in three C4def patients is described. The first patient lost one allograft after 6 years because of chronic allograft rejection. Back on dialysis, he suffered from meningitis caused by Neisseria menigitidis and Aspergillus. One year after a second transplantation under alemtuzumab induction, he developed fulminant Kaposi's sarcoma and died. His sister is now 6 years post-transplantation without complications. The third patient lost his first graft after 3 years because of chronic allograft nephropathy and recurrence of glomerulonephritis. He has now been living with a second graft for over 9 years. He suffered from pneumonia, a generalized varicella infection and Hemophilis parainfluenzae bronchitis. Patients with complete C4def are at increased risk for infection after kidney transplantation. Under certain precautions and with judicious use of immunosuppression, good long-term results are achievable. 相似文献

Background
Dense-deposit disease (DDD) is a rare glomerulopathy characterized by electron-dense deposits in the glomerular basement membrane. About 50 % of patients with DDD progress to end-stage kidney disease and require dialysis within 10 years of diagnosis, and the disease often recurs after renal transplantation.Case-Diagnosis/Treatment
We describe a 14-year-old girl with recurrent DDD in her transplanted kidney. Clinical onset was at 8 years of age, when steroid-resistant nephrotic syndrome was diagnosed with microhematuria, severe hypocomplementemia and normal kidney function. Although remission was initially observed after several plasma exchanges, nephrotic proteinuria returned and kidney function further declined 1 year later. The patient received a living-related kidney transplant. Initial allograft function was good, but proteinuria reappeared 3 months after transplantation, accompanied by a slight deterioration in kidney function. After histological confirmation of DDD recurrence and subsequent management with plasmapheresis, the patient was treated for 30 months with eculizumab, a humanized monoclonal antibody that binds to C5 complement protein. This intervention proved effective and resulted in complement inhibition, sustained remission of proteinuria and preservation of renal function. A graft biopsy 6 months later showed no progression of the renal lesions.Conclusions
Early clinical and histological recurrence of DDD in the transplanted kidney in this 14-year-old patient was treated for 30 months with eculizumab. The patient remains asymptomatic, has no proteinuria and her kidney function is intact. 相似文献10.
Early renal failure in Fabry's disease 总被引:1,自引:0,他引:1
Two young males were observed with renal failure from Fabry's disease. These two patients had progressive decrease of renal function and required hemodialysis at ages 16 and 24. Diagnosis was confirmed by low plasma galactosidase levels and by skin and kidney biopsy. Each has had a successful kidney transplant with good graft function, the 16-year-old patient for five years and the 24-year-old for two years. Although the renal impairment usually does not appear until the fourth or fifth decade of life. Fabry's disease should be considered in the differential diagnosis of renal failure in young males. 相似文献

Summary We describe the presumably first intentional ABO‐incompatible deceased‐donor kidney and pancreas transplantation with a severe antibody‐mediated rejection during a rebound of isoagglutinins. Rejection was successfully treated with eculizumab, which inhibits the terminal pathway of complement. Complement analysis (C3, C3d,g, and a modified assay of classical complement‐related hemolytic function) documented complement activation and confirmed that eculizumab completely blocked complement function. At 6 months, the patient had normal kidney and pancreas function, and histological evaluations revealed no evidence of sustained graft damage. This successful transplantation suggests that ABO barriers can safely be overcome without extensive preconditioning, when the complement inhibitor eculizumab is included. 相似文献

Thrombotic microangiopathy (TMA) is one of the hallmark vascular lesions of antiphospholipid syndrome nephropathy (APSN). These lesions are at high risk of recurrence after kidney transplantation. The complement pathway is thought to be active in this process. We used eculizumab to treat three consecutive kidney transplant recipients with posttransplant TMA due to APSN recurrence that was resistant to plasmapheresis and explored the complement deposition and apoptotic and vascular cell markers on the sequential transplant biopsies. Treatment with eculizumab resulted in a rapid and dramatic improvement of the graft function in all three patients and in improvement of the TMA lesions within the graft. None of these patients had TMA flares after eculizumab was withdrawn. At the time of TMA diagnosis, immunofluorescence studies revealed intense C5b‐9 and C4d depositions at the endothelial cell surface of the injured vessels. Moreover, C5b‐9 colocalized with vessels exhibiting a high rate of apoptotic cells. Examination of sequential biopsies during eculizumab therapy showed that TMA lesions, C4d and apoptotic markers were rapidly cleared but the C5b‐9 deposits persisted for several months as a footprint of the TMA. Finally, we noticed that complement inhibition did not prevent the development of the chronic vascular changes associated with APSN. Eculizumab seems to be an efficient method for treating severe forms of posttransplant TMA due to APSN recurrence. Terminal complement inhibition does not prevent the development of chronic APSN. 相似文献

Recurrence of hepatitis C virus (HCV)–associated membranoproliferative glomerulonephritis (MPGN) in the kidney transplant may lead to continuous graft deterioration and the need for further renal replacement therapy. The novel direct‐acting antiviral agents (DAAs) allow a highly effective and interferon‐free treatment option for chronic HCV‐infected patients. Data on the therapeutic safety and efficacy in HCV‐infected renal transplant patients are sparse, especially for patients with severe renal impairment. We report the case of a 63‐year‐old female HCV‐positive renal transplant patient with biopsy‐proven recurrence of MPGN in the renal graft 3 years after transplant. Because of rapid loss of transplant function and consecutive need for hemodialysis, we initiated a combined anti‐HCV–directed therapy regimen consisting of daclatasvir and simeprevir over 12 weeks. Viral clearance of HCV was obtained as early as 2 weeks after start of treatment. No adverse therapy‐associated side effects were observed, and immunosuppressive dosing remained unchanged. Importantly, graft function fully recovered and hemodialysis was stopped 2 mo after the end of daclatasvir/simeprevir treatment. We report the first case of successful recovery of dialysis‐dependent renal transplant failure after treatment of recurrent HCV‐associated MPGN in a kidney transplant recipient by curing the underlying HCV infection with a combination of novel DAAs. 相似文献

Focal segmental glomerulosclerosis (FSGS) is the most common form of post-transplant glomerulonephritis. We describe a case where a biopsy proved that early recurrence of FSGS on postoperative day 1 was the cause of delayed graft function. A 39-year-old man, on hemodialysis for 15 years due to polycystic kidney disease, received a cadaveric renal transplantation. On postoperative day 1, his hourly urine output decreased from 700–800 mL to 50 mL. The graft biopsy showed a mild acute kidney injury confusing nephrotic syndrome. On postoperative day 45, his creatinine level increased to 3.02 mg/dL with severe proteinuria. A kidney biopsy showed focal segmental glomerulosclerosis. On postoperative day 120, his creatinine level elevated again, concomitant with proteinuria. A kidney biopsy showed FSGS with antibody-mediated rejection. After plasmapheresis, his creatinine level decreased to 1.3 mg/dL with mild proteinuria. Once active in the allograft, de novo FSGS is a potentially aggressive process. In this case, it could be managed because of an accurate diagnosis and appropriate treatment. 相似文献

IntroductionRejection is the most important problem for renal graft function and survival. Complement system plays a key role in immune responses from host to graft. It was demonstrated that complement system activation is related with renal fibrosis. We evaluate clinical impact of complement deposition findings on biopsies in acute rejection episodes of pediatric renal transplant patients.MethodDemographics of the patients, graft functions, acute rejection episodes and graft loss were recorded from data files of 165 pediatric renal transplant patients. Findings of 98 renal biopsies were retrospectively evaluated.ResultsThirty three patients with kidney transplant had 44 acute rejection episodes (32 pure cellular acute rejection episodes / 1 pure humoral acute rejection episode / 11 combined acute cellular and acute humoral rejection episodes) proven by biopsy. C1q staining was positive in 7 biopsies, C3 staining in 15 biopsies and, C4d staining in 15 biopsies. 26 patients had graft fibrosis. All patients with a rejection history had a significant decrease in GFR value during follow-up. Patients who did not have fibrotic changes in first biopsy had same level of deterioration of GFR when compared with patients who had fibrotic changes in first biopsy.ConclusionWe could not demonstrate a significant relation between complement deposition and renal fibrosis, and between complement deposition and GFR values. Our data demonstrated that graft outcomes and graft loss after acute rejection episodes cannot be predicted only with complement deposition on graft or only with graft fibrosis. 相似文献

We present a case of a 45-year-old man who suffered from idiopatic membranoproliferative glomerulonephritis (MPGN) in the native kidney that relapsed after his first and second renal grafts. The patient was diagnosed in 1990 with lobular MPGN type I, receiving his first renal graft in 1996. In 2001, a biopsy showed recurrence of MPGN type I (rMPGN). He underwent a second renal graft in 2008. In January 2010, he experienced increased proteinuria and creatinine. Upon electron microscopy of a renal graft biopsy we diagnosed a new rMPGN. At the time of the biopsy, complement levels were normal, although C3 and C4 decreased further. We administered 12 plasmapheresis (PP) sessions and four doses of rituximab. Due to persistent renal impairment, we performed a new biopsy 3 months later, showing less severity of the acute lessions. He received a new cycle of treatment (PP + rituximab). One year later, his renal function was stable with a creatinine ranging between 2 and 2.5 mg/dL and a protein/creatinine ratio less than 1 mg/mg. We concluded that the treatment stopped the disease progression. 相似文献

The incidence and early recurrence after transplantation prove the specificity of the appearance of an electron dense alteration of kidney basement membrane often called dense intra-membranous deposit disease. Three new cases with dense deposit disease affecting the original kidneys have been followed-up after transplantation for periods ranging from 4 to 8 years and illustrate the natural history of the recurrence. Serial kidney biopsies showed the predominance of dense deposits near the mesangial area and the vascular pole. These deposits were also seen in some tubular basement membranes. Absence of cell proliferation was noted in all biopsies performed. Immunofluorescence studies revealed fixation of C3 alone. Histological signs of recurrence are compatible with the absence of clinical and biological signs. Transient or permanent proteinuria and microhematuria were common findings. Serum complement levels, measured after transplantation, were low in all three cases. Despite recurrence of the original glomerulonephritis, long-term survival of the graft was commonly observed, two cases being followed-up for 7 and 8 years. Patients with dense intra-membranous deposits glomerulonephritis should not be excluded from a transplantation program. One of the three cases reported here illustrates the exceptional association of recurrence of dense intramembranous deposits, de novo membranous glomerulonephritis and chronic rejection. 相似文献

BACKGROUND: Studies in animal models have shown that the alternative pathway of complement is activated in the kidney after ischemia/reperfusion. In addition, mice deficient in complement factor B, a necessary component of the alternative pathway, are protected from ischemic acute renal failure. The purpose of this study was to determine whether alternative pathway activation also occurs during the development of ischemic acute tubular necrosis in the human kidney. METHODS: Biopsies were identified from nine patients with morphologically normal kidneys and seven patients with evidence of acute tubular necrosis by light microscopy. Immunofluorescence microscopy was used to quantify and localize the complement activation products C3d and C4d. The results were correlated with available clinical data. RESULTS: Similar to mice, small amounts of activated C3d were present along the tubular basement membrane in normal kidneys. However, kidneys from patients with acute tubular necrosis had C3d complement deposition along a significantly greater number of tubules, and many of the tubules were completely circumscribed. In contrast, C4d was not detectable, indicating that complement activation occurred primarily via alternative pathway activation. CONCLUSION: Complement activation occurs in human ischemic acute tubular necrosis. As in rodents, complement activation along the tubular basement membrane after ischemia appears to occur principally via the alternative complement pathway. Because of this, an inhibitor of the alternative pathway might limit complement activation and inflammation after ischemia/reperfusion, thereby protecting the kidney from ischemic acute renal failure. 相似文献

BackgroundThis study aims to determine the ratio of delayed graft function in renal transplant recipients from living donors and the predictive value of hemodialysis time before transplant for delayed graft function.MethodsWe conducted a study on 116 adult patients who were diagnosed with end-stage kidney disease and were treated with hemodialysis and transplanted kidneys from living donors for 2 years (from June 2018 to June 2020). Delayed graft function event was collected for each patient.ResultsThe recipients had a median age of 36.5 years old, in which 55.2% of them were men, 4.3% of them had the diabetic mellitus, and the median hemodialysis duration was 6 months. The ratio of positive panel-reactive antibody was 33.6% and vascular reconstruction of the donor's kidney was 16.4%. The ratio of delayed graft function was 12.2% (14 of 116 patients). Delayed graft function significantly related to positive panel-reactive antibody, long duration of hemodialysis before transplant, and vascular reconstruction of donor's kidney with P < .001. Duration of hemodialysis before kidney transplant had a predictive value for delayed graft function (area under the curve, 0.83; P < .001).ConclusionDelayed graft function was not rare in renal transplant recipients from living donors. Duration of hemodialysis before kidney transplant was a good predictor for delayed graft function. 相似文献
