Heavy proteinuria after bone marrow transplantation (BMT) is rare. Pathology shows membranous glomerulonephritis (MGN) in most cases. After BMT, focal segmental glomerulosclerosis (FSGS) after resolution of MGN has not been reported. We describe a 13-year-old boy who had matched unrelated donor allogeneic BMT for relapsed acute lymphoblastic leukemia, complicated by chronic graft-versus-host disease. Nephrotic syndrome developed 1 year after BMT and renal biopsy revealed MGN. Immunosuppressive therapy achieved good clinical remission, and treatment was stopped after 15 months. He developed significant proteinuria 55 months later. The second renal biopsy showed FSGS without changes of MGN. This distinctive disease evolution gives inspiring implications. Complete morphological resolution of graft-versus-host disease-associated MGN, achieved in our case, has not been previously documented. Recurrent significant proteinuria after BMT is not necessarily due to previous renal lesion, and a repeat renal biopsy is indicated. The pathogenesis of MGN and FSGS are different, and different mechanisms of glomerular injury can interplay in a single patient after BMT. This case helps to expand our knowledge of the temporal morphological spectrum of renal lesions associated with BMT.

Clinical data from case reports of nephrotic syndrome including allogenetic hematopoietic stem cell transplantation (HSCT) suggest that there may be some relationship between chronic graft-versus-host disease (GVHD) and membranous nephropathy (MN). It is widely recognized T cells are crucial for the development of GVHD, and that T helper (Th) cells differentiate into at least two subsets, Th1 and Th2. The polarized situation between Th1 and Th2 cells is established to be important in animal models and human autoimmune diseases. In a chronic GVHD murine model a Th2 cell plays a pivotal role for the pathogenesis. In MRL/lpr mice, which is particularly valuable model for systemic lupus erythematosus, developed diffuse proliferative glomerulonephritis (DPGN) in Th1 environment and MN in Th2 environment. Similarly, Th2 cells may be predominantly activated in chronic GVHD, production and deposition of IgG4 in the glomeruli may develop MN. A hypothesis is: when the patient in period of chronic GVHD developed immune complex-mediated disease, IgG4 might be mainly produced in Th2 environment, and the deposition of IgG4 in the glomeruli may result in the formation of MN.

As early as 1978, the immunosuppressive effect of cyclosporine A (CsA), a metabolite of the fungus Tolypocladium inflatum (Borel, 1989), was reported to be effective in inhibiting organ rejection in patients receiving kidney transplants from mismatched cadaver donors (Calne et al., 1978) and in the treatment of graft-versus-host disease in patients with acute leukemia following bone marrow transplants (Powles et al., 1978). Today, CsA is still indicated to prevent rejection following solid organ transplantations, prevent and treat graft-vs-host disease following bone marrow transplants, and has also been used in the treatment of autoimmune disease such as psoriasis, rheumatoid arthritis, and nephrotic syndrome (Canadian Pharmacists Association, 2006). The effectiveness of CsA is derived from its ability to specifically and reversibly inhibit immunocompetent lymphocytes in the G(0) and G(1) phase of the cell cycle. The T-helper cells are the main target, but suppression of the T-suppressor cells also occurs. The production and release of lymphokines, including interleukin-2 are also inhibited (Novartis, 2005a). CsA can be administered intravenously as well as orally in the form of a solution or a soft gelatin capsule. The following review will focus on the evolution of the emulsion-based oral formulations from the first generation as Sandimmune to the second generation Neoral, both products of Novartis Pharmaceutical, as well as on the Sandimmune commercial intravenous formulation. The potential of alternative delivery systems, including micelles, micro- and nanoparticles, and liposomes, will also be discussed.

Complications of allogenic hematopoietic stem cell transplantation that occur in the first 100 days are considered early and those that begin 100 days after are considered late complications. Chronic graft-versus-host disease is the most common late complication of allogenic hematopoietic cell transplantation, which occurs in 60-80% of long-term survivors and causes significant morbidity and mortality. It is well known that it affects primarily the skin, mucous membranes, cells in the gastrointestinal tract and liver. The kidneys are not considered a target organ for chronic graft-versus-host disease in humans, although renal involvement in patients with chronic graft-versus-host disease, presenting as nephrotic syndrome, has been reported in patients who underwent allogenic transplantation. We present a case of chronic graft-versus-host disease that manifested as nephrotic syndrome after hematopoietic cell transplantation performed 3 years ago. Kidney biopsy revealed membrane nephropathy. Treatment with cyclosporine and methylprednisolone significantly reduced albuminuria.

Glomerular disease associated with nephrotic syndrome has rarely been recognized as a distinct complication of allogeneic hematopoietic cell transplantation. Case reports in the English and Japanese literature since 1988 have described variable glomerular histology, comprising mainly membranous glomerulonephritis (MGN) in almost two thirds and minimal change disease (MCD) in nearly one quarter of patients. Review of the literature reveals a close temporal relationship between the development of nephrotic syndrome shortly after cessation of immunosuppression and the diagnosis of chronic graft-versus-host disease (GVHD). An association of glomerular disease with simultaneous GVHD was seen in 47% of patients overall. Nephrotic syndrome followed GVHD within 5 months in 60% of the combined MCD and MGN reports. A decrease in immunosuppressive medication use was linked to nephrotic syndrome occurrence within 9 months in 63% of patients with MCD and MGN. MCD occurred earlier after hematopoietic cell transplantation, was diagnosed sooner after medication change, and exhibited a better prognosis in comparison with MGN. Glomerular lesions after hematopoietic cell transplantation may therefore represent the renal manifestation of GVHD. Further studies are warranted to delineate the pathogenesis of this complication.

We describe the case of a male patient who was diagnosed with acute monoblastic leukemia and received a peripheral stem cell transplantation (PSCT) with peripheral blood hematopoietic progenitors. Because he was in clinical remission with no evidence of chronic graft-versus-host disease (GVHD), immunosuppression was withdrawn, and he developed nephrotic syndrome (NS) months later. A kidney biopsy showed focal segmental glomerulosclerosis (FSGS) as part of the GVHD. Soon after the reintroduction of previous immunosuppressive therapy, we observed a complete remission of the NS.

Graft-versus-host disease is one of the most frequent complications occurring after haematopoietic stem cell transplantation. Recently, renal involvement has been described as a manifestation of chronic graft-versus-host disease. Immunosuppression seems to play a major role: clinical disease is triggered by its tapering and resolution is achieved with the resumption of the immunosuppressive therapy. Prognosis is apparently favourable, but long term follow up data are lacking.We report a case of a 53-year-old man who developed nephrotic syndrome 142 days after allogeneic stem cell transplantation for acute myeloid leukaemia. Onset of nephrotic syndrome occurred after reduction of immunosuppressants and was accompanied by manifestations of chronic graft-versus-host disease. Histological examination of the kidney was consistent with Minimal Change Disease. After treatment with prednisolone and mycophenolate mofetil he had complete remission of proteinuria and improvement of graft-versus-host disease. Eighteen months after transplantation the patient keeps haematological remission and normal renal function, without proteinuria.Since patients with chronic graft-versus-host disease might be considered at risk for development of nephrotic syndrome, careful monitoring of renal parameters, namely proteinuria, is advisable.

There are 3 clearly distinct clinical entities that occur after HCT: TMA, idiopathic CKD, and nephrotic syndrome. The potentially independent role of GVHD and chronic inflammation in the development and progression of idiopathic CKD warrants further investigation. CKD after HCT is a relatively common occurrence. As the indications for and number of transplants performed world wide increases, so will the burden of kidney disease. Identifying those patients at risk for the development of CKD will be important for potential intervention and prevention of CKD and progression to end-stage renal disease in this patient population. There are those patients who will develop CKD that is not related to TBI or the conditioning regimen but rather to complications and/or therapy that occur after HCT, specifically aGVHD and cGVHD and prolonged calcinuerin inhibitor use. The burden of management will fall not only to the nephrologists but the oncologist as well to ensure close monitoring of renal function, blood pressure, and urinalyses posttransplant. It may be that our energies have been misdirected in trying to reduce exposure to TBI, and rather we should try to decrease the inflammatory and cytokine effects of GVHD and reduce exposure to calcineurin inhibitors to prevent CKD in this population of patients.

We experienced four patients who suffered from nephrotic syndrome after a successful allogeneic hematopoietic stem cell transplantation (HSCT). These cases were seen in the nineteen-year period from September, 1986 to June, 2005. Our data showed that the incidence of nephrotic syndrome was 0.51% (3 out of 585 HSCT patients) in our hospital. Pathological findings of their renal biopsy specimens revealed that 3 patients had membranous nephropathy and that one patient had minimal change disease. Three patients were positive for anti nuclear antibody. Administration of prednisolone or cyclosporine improved the nephrotic syndrome, leading all patients to a complete or almost complete remission. The nephrotic syndrome occurred at 17 to 25 months after HSCT and accompanied the relapse of chronic graft-versus-host disease (GVHD), possibly due to the termination or a decrease of immunosuppressant administration in all patients. This suggests that immunological abnormality associated with chronic GVHD may be partly involved.

Nephrotic syndrome (NS) is a well documented complication after allogeneic peripheral blood stem cell transplantation. It is usually due to autoimmune glomerulonephritis and thought to be a clinical manifestation of graft versus host disease. NS has also been reported to be associated with other hematological malignancies. We report a case of nephrotic syndrome in a patient who relapsed after allogeneic peripheral blood stem cell transplantation (PBSCT) for chronic myeloid leukemia (CML). The renal biopsy was suggestive of minimal change disease. There was no other evidence of graft versus host disease. He was treated with high dose prednisolone, with no response and finally succumbed to the underlying disease.
