We report two cases of nephrotic syndrome with minimal glomerular change complicating alpha-interferon therapy. CASE REPORTS: The first patient was a 60-year-old man with Waldenstr?m's disease who was given 1 million units of alpha-interferon three times a week for 22 months. Acute renal failure developed when a second protocol was started. Renal biopsy revealed intraglomerular deposits and no cellular proliferation. Total remission could not be achieved with corticosteroids. The second case was a 46-year-old man given high dose alpha-interferon (15 million units 3 times a week) for lymph node metastasis of a malignant melanoma. A nephrotic syndrome without renal failure developed during the third month of treatment. Minimal glomerular involvement was seen. Symptomatic treatment led to resolution of the nephrotic syndrome. DISCUSSION: Nine other cases of nephrotic syndrome complicating alpha-interferon therapy have been reported in the literature.  相似文献

A patient with severe nephrotic syndrome who was too debilitated to undergo surgical nephrectomies, underwent therapeutic bilateral renal artery occlusion by the selective injection of isobutyl 2-cyanoacrylate into the renal arteries. The therapy resulted in dramatic cessation of urine flow and elimination of proteinuria.  相似文献

Castleman's disease is an uncommon lymph node disorder which can be associated with renal disease. In this report we describe a patient with fever, weight loss, anorexia, increase in inflammatory proteins, anemia and nephrotic syndrome. Castleman's disease, plasma cell type, was diagnosed by histologic analysis after surgical excision of a pelvic lymph node. The disease was considered localized, since further investigations did not show any other pathologic mass. After resection of the pelvic lymphoid mass, clinical remission of systemic symptoms and laboratory abnormalities was observed, with the exception of the nephrotic syndrome. Renal biopsy was performed and showed a pattern compatible with fibrillary glomerulonephritis. Progressive decline in renal function was observed, despite immunosuppressive therapy.  相似文献

Pathomorphological findings on nephrobiopsies from two groups of patients with NSAID-induced kidney lesions are provided. In the first group (9 patients) the disease developed in patients of different age after short-term use of NSAID and was clinically manifested by acute renal failure with extrarenal allergic symptoms (skin, rash, eosinophilia). Morphological features were acute tubulo-interstitial nephritis without glomerular lesions. In the second group (23 patients) the disease developed after longterm use of NSAID in older patients with a compromised renal blood circulation presenting clinically with nephrotic syndrome, and morphologically by acute tubulo-interstitial nephritis with minimal change (lipoid nephrosis).  相似文献

We report a 19-year-old man who developed a cerebral infarction in the territory of the anterior choroidal artery and showed a hypercoagulable state and nephrotic syndrome after diarrhea and appetite loss. He had suffered from nephrotic syndrome from the age of three and had been treated for five years. MR-angiography showed an occlusion originating in the right internal carotid artery. The right anterior and middle cerebral arteries were imaged from the left internal carotid artery via the anterior communication artery. He showed symptoms of left hemiparesis, agnosia, loss of activity, anasarca and left hypacusis following his clinical course, but had recovered from all but left hemiparesis following medical treatments including steroid therapy. The histologic finding by a renal biopsy revealed focal glomerulosclerosis. In this case, we considered that when he was in a hypercoagulable state and had a second attack of nephrotic syndrome because of inflammation and dehydration due to diarrhea and appetite loss, his hypercoagulable state grew worse, and he then developed a cerebral infarction. When one see a patient with nephrotic syndrome, one should be attentive to the possibility of a complication of cerebral infarction.  相似文献

Two cases with different and not previously described fatal renal complications during treatment with penicillamine are reported. A man with seronegative rheumatoid arthritis with features of systemic lupus erythematosus was treated with penicillamine for six months and developed a mild membranous glomerulonephritis and a severe renal vasculitis leading to uremia and death. A woman with primary biliary cirrhosis was treated with penicillamine for nine months and developed a nephrotic syndrome, the renal biopsy showing minimal change glomerulonephritis. The nephrotic syndrome responded to prednisone but the patient died, probably from septicemia. Penicillamine may thus cause glomerular damage without deposition of immune complexes. A restricted use of the drug is recommended.  相似文献

Patients with steroid-resistant focal and segmental glomerulosclerosis (FSGS) have a poor prognosis but may benefit from high-dose methylprednisolone or cyclosporine A therapy. Ten patients were treated with a protocol of methylprednisolone infusions for 8 weeks followed by a combination of cyclosporine A and alternate-day prednisone for maintenance of remission for 2 weeks. Eight of ten patients remitted the nephrotic syndrome within 8 weeks of beginning treatment. One patient remitted edema but remained proteinuric, and one did not respond. After observation for 12-24 months, seven patients maintained remission with normal glomerular filtration rate. One non-responder had renal insufficiency and one patient had secondary non-response and end-stage renal disease. No patients developed hypertension. One patient had the diagnosis of Hodgkin disease made after 10 months of therapy. Follow-up renal biopsy in four patients showed no evidence of progressive interstitial disease. There were no other major side effects. Steroid-resistant FSGS may be successfully treated with the described protocol. Additional studies will be needed to determine if this approach prevents progression of renal disease.  相似文献

A 35-year-old man with idiopathic eosinophilic fasciitis (EF) and morphea developed renal disease characterized by microscopic hematuria, nephrotic range proteinuria, and rapidly progressing hypertension, an association that has not previously been reported in EF. Initial clinical symptoms of EF began in July 1989; peripheral eosinophilia peaked at 30% in August 1990; an abnormal urinalysis was first observed in March 1992 and subsequently a renal biopsy was performed. Renal biopsy demonstrated focal segmental glomerulosclerosis and a subepithelial immune-type deposit. Partial fasciectomy and a course of methotrexate resulted in overall functional improvement of his extremities. Proteinuria and hematuria was reduced during methotrexate therapy.  相似文献

Cyclosporine was introduced in 1981 as an immunosuppressive agent in renal transplantation. Its use was soon extended to the treatment of various glomerular disorders. In light of its known immunomodulating effects, the use of cyclosporine has been most prominent in those glomerular diseases thought to have an immune basis. The most careful studies of cyclosporine in glomerular diseases have been performed in the pediatric population with idiopathic nephrotic syndrome (i.e., minimal change disease and focal segmental glomerulosclerosis), although data are accumulating regarding efficacy and safety in adults with idiopathic nephrotic syndrome. In patients who are steroid-dependent, cyclosporine therapy can induce complete or partial remission in a significant proportion of cases; success rates in patients with steroid-resistant nephrotic syndrome are less encouraging. Treatment with cyclosporine allows for dose reduction or elimination of corticosteroids, and the consequent salutary effect on growth in the child and glucose and bone metabolism in all patients. Studies that suggest a potential benefit of cyclosporine in recurrent nephrotic syndrome in renal allografts and in other glomerular diseases are also discussed.  相似文献

A 25-year-old woman complained of anasarca and was admitted to Sakura National hospital on the presumptive diagnosis of nephrotic syndrome with 10.7 g of 24-hour urinary protein. At first, lupus nephritis with antiphospholipid antibody syndrome was suspected because of prolongation of APTT, existence of lupus anticoagulant and elevation of serum anticardiolipin antibody titer (IgM) in addition to positive ANA, lymphocytopenia and the biologically false positive test for syphilis (BFPTS). On day 28 of hospitalization, renal biopsy findings revealed severe endocapillary cell damage, such as swelling and proliferation of endothelial cells, fragmentation and double contour of the basement membrane walls, which were located only in the capillary lumens with a few thrombi. Immunofluorescent micrography revealed the absence of specific immunoglobulin or complement deposit. Therefore, the diagnosis of lupus nephritis was negated as these findings were suggestive of characteristic glomerulopathy due to primary antiphospholipid antibody syndrome. She was treated initially with oral prednisolone 60 mg and intravenous infusion of heparin 20,000 units daily. Moreover, cyclophosphamide 750 mg was administered intravenously as pulse therapy on day 13 as her serum level of CH50 had fallen suddenly, and hemodialysis was necessary because her renal function had deteriorated and she was suffering from cough and orthopnea with overhydratin. After the combined therapy, BFPTS disappeared and APTT returned to the normal range: dialysis treatment was not required further after the 4th hemodialysis. Thereafter, renal function improved and complete remission of nephrotic syndrome was obtained. This patient was a case of primary antiphospholipid antibody syndrome in which endothelial cell damage was located exclusively in the capillary lumens and pulse cyclophosphamide therapy in addition to prednisolone and anticoagulant was effective. We present this instructive case to promote understanding of the pathogenesis of primary antiphospholipid antibody syndrome.  相似文献

This is a report about three siblings (one boy and two girls) suffering from a clinically- and morphologically-identical form of renal disease. The disease began in each case with symptomless proteinuria at the age of 3 years and proceeded after several years to the full-blown picture of idiopathic nephrotic syndrome with the rapid development of renal insufficiency. Histologically, minimal proliferative intercapillary glomerulonephritis with focal sclerosis was found in all 3 cases. This condition was resistant to steroid and immunosuppressive therapy. The incidence and the morphological, clinical and therapeutic peculiarities and the prognosis of familial nephrotic syndrome are discussed on the basis of these case reports.  相似文献

Eighteen out of 57 patients (31-6 per cent) suffering from Familial Mediterranean Fever (FMF) were found to have the nephrotic syndrome, histologically proven amyloidosis and progressive renal failure. In 14 cases renal function deteriorated rapidly after the first appearance of significant proteinuria, and 12 cases (66-7 per cent) required regular haemodialysis. Seven of these patients, seen in the early stages of renal impairment, were subsequently diagnosed clinically as probably having developed renal vein thrombosis. There was radiological proof of intrarenal or major renal vein occlusion in five which in one patient progressed to inferior vena cave obstruction. Treatment with heparin, plasminogen activators and fibrinogenolytic agents was disappointing although renal function has stabilized in one patient on long term oral anticoagulant therapy. It is suggested that renal vein thrombosis is common in FMF with renal amyloidosis and usually causes rapid deterioration of function and irreversible renal failure requiring dialysis. Renal phlebography may delineate clot in the main renal veins or indicate areas of reduced blood flow due to thromboses in intrarenal venules. Treatment is only partially satisfactory but there is some evidence to suggest that renal phlebography should be undertaken promptly when renal function begins to fall followed by anticoagulant therapy to prevent further thromboembolic complications.  相似文献

A patient presented with a severe nephrotic syndrome and a renal biopsy consistent with early focal segmental glomerulosclerosis (FSGS). After a year of intensive immunosuppressive therapy proteinuria was unabated and renal function began to deteriorate. Treatment with weekly plasmapheresis combined with moderate doses of prednisone and azathioprine produced a dramatic decrease in proteinuria and serum creatinine. A marked fall in the B-cell population occurred during treatment, as well as an increase both in T-lymphocytes of the mature CD4+ helper/suppressor phenotype and in the immature/cytotoxic CD8+ phenotype. Activation of the immune system during treatment was demonstrated by an increase in the rate of spontaneous proliferation of peripheral blood mononuclear cells and an increase in T-cell expression of the interleukin-2 receptor.  相似文献

Results of dietotherapy used in dealing with 68 patients suffering from chronic diffuse glomerulonephritis at the stage of chronic renal incompetence and with 50 others with the nephrotic syndrome are reported. The pertinent observations and investigations indicate that the most adequate ration for patients with chronic renal insufficiency is the one containing 40 g of protein. With a far advanced renal incompetence the treatment is to be started with a diet containing 20 g of protein and then, as the condition of the patients gets better, puts them on a diet with 40 g of protein. Observations have also brought out the fact that patients with nephrotic syndrome are in need of a diet containing 1.5-2 g of protein per 1 kg of an edema-free body weight of the patient.  相似文献

Complicating disorders in various organs outside the intestinal tract are common in ulcerative colitis. This report deals with the occurrence of nephrotic syndrome in two patients with long-standing ulcerative colitis. In the patient studied in most detail, 2 episodes have taken place, the first developing into uremia. After colectomy had been performed, rapid improvement of renal function took place. The morphological changes in kidney biopsies were compatible with the presence of focal glomerular sclerosis. Activity in the complement system and a favorable response to steroid treatment indicate that humoral immune mechanisms are of pathogenetic importance with regard to the renal disease in these two patients. To our knowledge nephrotic syndrome has not previously been described as a complication to ulcerative colitis.  相似文献

Renal amyloidosis is a rare disease when compared to other kidney diseases. During the period of last fifteen years, at the Institute of Nephrology and Immunology in Sarajevo renal amyloidosis was diagnosed with 15 patients. The disease occurred more often with men than with women. Only during 1988, renal amyloidosis was revealed and followed up with five patients. The most common clinical manifestations of renal amyloidosis are nephrotic syndrome and chronic renal failure, with respective laboratory findings. Using immunofluorescent analysis of the kidney biopsy material, we discovered deposits of immunoglobulins of different intensity and deposits of lambda and kappa light chains of immunoglobulins. The intensity of lambda light chains is greater than that of kappa chains. The analysis of light microscopy showed nodular mesangial deposits and deposits along GBM without proliferation. The diagnosis of amyloidosis was confirmed by staining of amyloid. Application of therapy for amyloidosis was without any effect. Although renal amyloidosis is a rare disease, we want to point out disease as being an etiologic factor in nephrotic syndrome.  相似文献

Hyperlipidemia has been implicated in the pathogenesis of experimental progressive glomerulosclerosis, but its role in human renal injury is controversial. This report describes a 12-yr-old boy presenting with massive proteinuria, hepatomegaly, anemia, severe mixed hyperlipidemia, and progressive renal failure. The initial renal biopsy disclosed large numbers of foam cells that were shown to be monocytes. Evidence is presented suggesting that apoprotein-E2 homozygosity in our patient, together with an 88% reduction in plasma lipoprotein lipase activity associated with severe nephrotic syndrome, is responsible for the atypical clinical features, lipoprotein phenotype III with chylomicronemia, and renal lipidosis. A regimen of dietary lipid restriction, gemfibrozil, and niacin resulted in significant but partial improvement of the dyslipidemia and resolution of the hepatomegaly and ascites. This report stresses the importance of characterizing unique lipid disorders in patients with nephrotic syndrome in order to prescribe effective lipid-lowering strategies. Moreover, the striking resemblance of the clinical and nephrohistologic features of this patient to those occurring in experimental models of coexisting glomerular injury and hyperlipidemia led to the speculation that, in this setting, the hyperlipidemia may contribute to the development of progressive glomerulosclerosis.  相似文献

Type I carbohydrate-deficient glycoprotein (CDG) syndrome is a genetic multisystem disorder generally without overt renal problems. We report a neonate with neurological abnormalities and congenital nephrotic syndrome of diffuse mesangial sclerosis type. Serum transferrin isoelectric focusing showed the typical abnormalities of type I CDG syndrome. Normal transferrin focusing findings in other patients with similar renal problems excluded the possibility of a secondary biochemical phenomenon. The diagnosis of type I CDG syndrome was confirmed by demonstration of a deficiency of phosphomannomutase. No evidence of pontocerebellar atrophy was found in imaging or at autopsy. We conclude that congenital nephrotic syndrome may occur in type I CDG syndrome, and that this diagnosis should be considered in patients with congenital nephrotic syndrome. Absence of pontocerebellar atrophy does not exclude the diagnosis of type I CDG syndrome.  相似文献

Urinary protein excretion is generally less than 1 g/24 h in autosomal dominant polycystic kidney disease (ADPKD), and the association of the nephrotic syndrome with this condition is considered rare. A patient with ADPKD associated with nephrotic-range proteinuria is described. She exhibited a relatively rapid impairment of her renal function. An open renal biopsy revealed focal segmental glomerulosclerosis (FGS) with features consistent with secondary FGS. Twenty-one patients with ADPKD and nephrotic syndrome were retrieved from the literature. Fourteen of them (including this case) had a histopathologic evaluation, and FGS was the dominant diagnoses (five patients). Next in frequency were minimal-change disease and membranous nephropathy, with two patients each. Five other patients had a variety of diagnoses. Thus, it is difficult to ascertain if these associations are coincidental or represent a specific pathogenetic relationship. The evaluation of the data also suggests that the presence of proteinuria and nephrotic syndrome accelerates the course of ADPKD toward ESRD.  相似文献

OBJECTIVE: To analyze the use of Cyclosporine (CyA) in nephrotic syndrome. METHODS: Thirty five children of mean age of 5.9 years with steroid dependent (n = 26) or steroid resistant (n = 9) primary nephrotic syndrome with normal renal functions and who received CyA were studied. CyA was used at a dosage of 6-7 mg/kg/day orally in two divided doses. The mean duration of therapy was 9.6 weeks. All received a minimum of 8 weeks of CyA therapy. In a few who received longer therapy, the dose was reduced to 4 mg/kg/day. All patients were monitored serially for hepatotoxicity and nephrotoxicity. The nephrotic state was evaluated serially with biochemical tests and followed up for a mean period of 2.55 years. RESULTS: Thirty one patients completed the study. The response to therapy was categorized into 5 groups-no response (4 patients), good response (4 patients), partial response (4 patients), cyclosporine dependence (16 patients), and infrequent relapsers (3 patients). Good response was defined as complete remission lasting for at least one year after cessation of therapy. Patients who showed partial response had reduction in quantitative proteinuria and needed less diuretics. Sixteen patients went into complete remission while on therapy but relapsed within 3 months of discontinuation (CyA dependence). The response to CyA correlated more with steroid-responsiveness than with the underlying histopathology. The drug was well tolerated. CONCLUSION: In steroid-dependent or steroid-resistant nephrotic children with normal renal functions, CyA therapy may be considered as one of the possible therapeutic options. Our results suggest that a longer duration of CyA therapy may possibly be indicated in these cases.  相似文献
