The diagnosis of recurrent renal disease after transplantation is dependent on an accurate and complete diagnosis of the initial cause of renal failure and a similar determination of the cause of graft failure. To be classified as recurrent, the disease in the renal graft must be identical to that seen in the native kidneys. Recurrence of disease accounts for less than 2% of all graft failures, but the overall incidence of recurrent disease is probably 5 to 10 times more common. The most frequent cause of recurrent disease is glomerulonephritis, which was first recognized to recur soon after renal transplantation was introduced. It was then recognized that a variety of metabolic disorders would recur, but it has taken 25 years of experience for a clear picture to emerge of recurrence in most conditions. No initial cause of renal failure poses a contraindication to at least one attempt at transplantation, although with Fabry's disease and oxalosis, a special assessment of the risks for the individual recipient is warranted. In some patients, experience has shown the need for a delay in the commitment to transplantation (eg, in those with anti-glomerular basement membrane [GBM] antibody glomerulonephritis or Henoch Schonlein purpura), the need for the choice of a particular immunosuppressive regimen (eg, in hemolytic uremic syndrome [HUS]), the need for avoidance of primary nonfunction (eg, in oxalosis), and the desirability of avoiding live kidney donation (eg, in heterozygote donors in Fabry's disease, high-risk recipients with focal glomerulosclerosis, and in recipients with HUS). Probably all types of glomerulonephritis recur, but with great variation in frequency and severity. In some forms of glomerulonephritis, recurrence may be frequent and definite on histopathological criteria but may only have a minor clinical expression (eg, dense deposit disease, anti-GBM antibody glomerulonephritis, IgA nephropathy), but in others, recurrence is less predictable yet it is clearly associated with premature graft failure (eg, focal glomerulosclerosis, membranous nephropathy). A common theme emerging is that where the initial glomerulonephritis is aggressive and causes kidney failure over a short time, recurrence is more likely, and when present, it will lead to graft failure with an increased frequency. Clinical manifestations, the frequency of recurrence, and the prognosis of the graft are now identified for most conditions. Unexpected observations have included the rarity of recurrent systemic lupus erythematosus (SLE), the immediate return of heavy proteinuria in focal glomerulosclerosis, and the predictable return of dense deposit disease.(ABSTRACT TRUNCATED AT 400 WORDS)

We present the first female patient to exhibit Fabry-like myelin bodies in the glomerular epithelial cell in association with IgA nephropathy. This previously healthy 36-year-old woman presented with proteinuria and hematuria without skin lesions. Renal biopsy showed typical IgA nephropathy, with paramesangial deposits, mesangial proliferation and scattered myelin bodies. The leukocytic alpha-galactosidase A activity was abnormally low. She had no family history of Fabry's disease nor the characteristic features, such as skin lesion, neuralgia, or hypohidrosis. Fabry's disease is diagnosed from the renal biopsy findings and the activity of alpha-galactosidase A in leukocytes and/or fibroblasts. We diagnosed the present case with Fabry' disease and IgA nephropathy from these results.

Virtually all diseases affecting the native kidney recur in the kidney transplant with the exception of Alport syndrome, polycystic kidney disease, hypertension, chronic pyelonephritis, and chronic interstitial nephritis. Fortunately, in the majority of patients, recurrence of the original disease has minimal clinical impact, with only approximately 5% of all graft loss occurring as a result of recurrent disease. The primary renal diseases that commonly recur include membranoproliferative glomerulonephritis type II, IgA nephropathy, and focal and segmental glomerular sclerosis. The most common systemic disease that recurs is diabetic nephropathy. Living-related transplantation should be used with caution in patients with the hemolytic uremic syndrome, recurrent focal and segmental glomerular sclerosis, and membraneous glomerulonephritis. Fabry disease and primary hyperoxaluria type I are no longer absolute contraindications to kidney transplantation.

A 28-year-old male patient with both IgA nephropathy and an unusual case of Fabry's disease has been followed for 10 years. Diagnosis of both these diseases was made by histological examination of renal biopsy tissues and the enzyme activities of alpha-galactosidase A. Serial biopsies revealed the hithertofore unrecognized process of glomerular glycolipid accumulation peculiar to Fabry's disease at the initial stages of the disease. Physical examinations and routine laboratory analyses failed to show significant signs of Fabry's disease throughout the 10-year period. While alpha-galactosidase A activity is markedly decreased in the plasma of this patient as in classical Fabry hemizygotes, the activity in leukocytes and culture fibroblasts showed a considerable residual activity. Fabry's disease associated with IgA nephropathy apparently is extremely rare, and the present subclinical case is unique in that the early stages of substrate accumulation are demonstrable.

We report a 16-year-old girl and her one-year-younger sister, both heterozygous for the c.34del24 mutation of the GLA (alpha-galactosidase A) gene, which they inherited from their father who is affected by Fabry disease (FD). Both girls presented with macrohematuria and rapidly progressing proteinuria. Urine analysis revealed glomerular hematuria and a nephrotic range of proteinuria suggesting a concomitant glomerulonephritis. Light microscopy of kidney biopsy was characteristic of IgA nephropathy (IgA deposits in mesangial areas and glomerular capillary loops, and mesangial hypercellularity), whereas electron microscopy showed changes typical of Fabry disease (multiple osmiophilic inclusions in the subendothelial and mesangial areas). These two cases and similar reports in the literature suggest that IgA nephropathy in FD is not merely coincidental.

Fabry disease (FD) is an X-linked disorder of glycosphingolipid catabolism that results from a deficiency of the lysosomal enzyme alpha-galactosidase A. This defect leads to the accumulation of its substrates, mainly globotriaosylceramide, in lysosomes of cells of different tissues. Different studies have shown the involvement of immunopathologies in different sphingolipidoses. The coexistence of FD and immune disorders such as systemic lupus erythematosus, rheumatoid arthritis and IgA nephropathy, has been described in the literature. The aim of this study was to evaluate the prevalence of a group of autoantibodies in a series of Argentine FD patients. Autoantibodies against extractable nuclear antigens (ENAs), double-stranded DNA, anticardiolipin and phosphatidylserine were assayed by ELISA. Lupus anticoagulants were also tested. Fifty-seven per cent of the samples showed reactivity with at least one autoantigen. Such reactivities were more frequent among males than among females. Antiphospholipid autoantibodies were detected in 45% of our patients. The high rate of thrombosis associated with FD could be related, at least in part, to the presence of antiphospholipid autoantibodies in Fabry patients. We found the presence of ENAs, which are a characteristic finding of rheumatological diseases, previous a frequent misdiagnosis of FD, in around 39% of the cases. The detection of a high level of autoantibodies must be correlated clinically to determine the existence of an underlying autoimmune disease. With the recent development of therapy, the life expectancy in FD will increase and autoimmune diseases might play an important role in the morbidity of FD.

To establish the role of electron microscopy in the diagnosis of glomerular diseases we reviewed retrospectively 113 renal biopsies. The biopsies were included in this study if tissue was received for light microscopy, immunofluorescence and electron microscopy. The biopsy was assigned to one of the three following categories on the contribution of the ultrastructural findings to the primary diagnosis: essential, important, and not required. Our study revealed that electron microscopy was essential to establish the primary diagnosis in 35 cases (31.0%), was important, but did not alter the preliminary diagnosis in 15 cases (13.3%) and in 63 cases (55.7%) the ultrastructural examination was not needed to confirm the diagnosis. Electron microscopy was essential to create diagnosis in a total of two cases of thin basement membrane disease, in nephropathy in Alport syndrome, in nephropathy in Fabry disease, and was necessary for establishing final diagnosis in 12 cases (85.7%) of minimal lesion. On the basis of electron microscopy it was also possible to establish the precise diagnosis of subtypes in mesangiocapillary glomerulonephritides, describe the stage of membranous glomerulopathy, and find thickening of glomerular basement membrane in the pre-diabetic state. Moreover, ultrastructural examination was helpful to differentiate membranous and mesangiocapillary glomerulonephritis, minimal change nephropathy and early membranous lesions, and distinguish membranous lupus nephritis from idiopathic membranous nephropathy The electron microscopy findings were not of any help in establishing the diagnosis and did not obtain any valuable information in all cases of amyloid nephropathy and IgA nephropathy, as well as in the majority of focal segmental glomerulosclerosis, extracapillary glomerulonephritides, and mesangial proliferative glomerulopathies. In conclusion, the results showed that in 44.3% of glomerulopathies the ultrastructural study provides fundamental or important diagnostic information, and therefore electron microscopy still remains a useful tool in the diagnosis of glomerular diseases.

The kidney is one of the most important organs that play a crucial role in homeostasis and, therefore, congenital or acquired renal dysfunction causes refractory diseases, i.e., Alport's syndrome, Fabry's disease, diabetic nephropathy, IgA nephropathy, kidney cancer, transplant glomerulopathy. Nucleic acid transfection technology to the kidney is indispensable for the progress of biomedical research and the realization of gene therapy and nucleic acid drug for renal diseases. Control of renal nucleic acid transfection was difficult because of the structural complexity; however, the study of recombinant virus, synthetic carrier and physical force-mediated nucleic acid transfection to the kidney has advanced. Recombinant virus and synthetic carrier-mediated methods require long-term block of the blood or urinary flow for efficient transfection of nucleic acid because of the rich blood flow of the kidney. In contrast, physical force-mediated methods that transfect with nucleic acid via transient membrane permeability do not apprehend ischemia-reperfusion injury and, therefore, may be beneficial for nucleic acid transfection to the kidney. In this article, we collect the information of therapeutic gene, target molecule of the nucleic acid drug and target cells for renal diseases and structural property of the kidney from the point of view of nucleic acid transfection. Additively, current status of nucleic acid transfection technology to the kidney is reviewed.

Renal transplantation (Tx) is the treatment of choice for end-stage renal disease. The incidence of acute rejection after renal Tx has decreased because of improving early immunosuppression, but the risk of disease recurrence (DR) is becoming relatively high, with a greater prevalence in children than in adults, thereby increasing patient morbidity, graft loss (GL) and, sometimes, mortality rate. The current overall graft loss to DR is 7-8%, mainly due to primary glomerulonephritis (70-80%) and inherited metabolic diseases. The more typical presentation is a recurrence of the full disease, either with a high risk of GL (focal and segmental glomerulosclerosis 14-50% DR, 40-60% GL; atypical haemolytic uraemic syndrome 20-80% DR, 10-83% GL; membranoproliferative glomerulonephritis 30-100% DR, 17-61% GL; membranous nephropathy approximately 30% DR, approximately 50% GL; lipoprotein glomerulopathy approximately 100% DR and GL; primary hyperoxaluria type 1 80-100% DR and GL) or with a low risk of GL [immunoglobulin (Ig)A nephropathy 36-60% DR, 7-10% GL; systemic lupus erythematosus 0-30% DR, 0-5% GL; anti-neutrophilic cytoplasmic antibody (ANCA)-associated glomerulonephritis]. Recurrence may also occur with a delayed risk of GL, such as insulin-dependent diabetes mellitus, sickle cell disease, endemic nephropathy, and sarcoidosis. In other primary diseases, the post-Tx course may be complicated by specific events that are different from overt recurrence: proteinuria or cancer in some genetic forms of nephrotic syndrome, anti-glomerular basement membrane antibodies-associated glomerulonephritis (Alport syndrome, Goodpasture syndrome), and graft involvement as a consequence of lower urinary tract abnormality or human immunodeficiency virus (HIV) nephropathy. Some other post-Tx conditions may mimic recurrence, such as de novo membranous glomerulonephritis, IgA nephropathy, microangiopathy, or isolated specific deposits (cystinosis, Fabry disease). Adequate strategies should therefore be added to kidney Tx, such as donor selection, associated liver Tx, plasmatherapy, specific immunosuppression protocols. In such conditions, very few patients may be excluded from kidney Tx only because of a major risk of DR and repeated GL. In the near future the issue of DR after kidney Tx may benefit from alternatives to organ Tx, such as recombinant proteins, specific monoclonal antibodies, cell/gene therapy, and chaperone molecules.

We present a 22-year-old male patient who showed both classical Fabry disease and IgA nephropathy. He had proteinuria (1.5 g/day), hypohidrosis and neuralgia with fever. Serum creatinine and blood urea nitrogen were 0.9 mg/dL and 11.4 mg/dL, respectively. Renal biopsy showed strikingly vacuolated podocytes and tubular epithelium cells. Myelin-like bodies were detected in podocytes, mesangial cells, endothelial cells and tubular epithelium cells by electron microscopy. On immunofluorescence microscopy, IgA and C3 deposits were detected in mesangial areas. From these results and a markedly low level of alpha-galactosidase A activity, this patient was diagnosed as having classical Fabry disease and IgA nephropathy.
