1/188. nephrotic syndrome with mesangial proliferative glomerulonephritis induced by multiple wasp stings.We report the case of a young male who developed severe nephrotic syndrome within 2-3 weeks after being stung by 3 wasps. A percutaneous kidney biopsy specimen revealed mesangioproliferative glomerulonephritis with occasional subepithelial deposits suggestive of early membranous nephropathy. The patient was treated with oral prednisone 60 mg/day with no significant clinical response after 4 weeks, at which point he was started on oral cyclophosphamide, 100 mg/day, while the prednisone dose was tapered to 20 mg every other day over a 2-week period. Six months after initiation of cyclophosphamide, he still has severe nephrotic syndrome. We also briefly review the literature on hymenoptera sting associated nephrotic syndrome.- - - - - - - - - - ranking = 1keywords = nephropathy (Clic here for more details about this article) |
2/188. Effect of camostat mesilate on urinary protein excretion in three patients with advanced diabetic nephropathy.Effective treatment has not yet been established for patients with persistent proteinuria and hypoproteinemia related to advanced diabetic nephropathy. We report three patients with diabetic nephropathy presented with the nephrotic syndrome who showed a marked decrease in proteinuria following the administration of camostat mesilate, a protease inhibitor. Each patient was resistant to treatment with an angiotensin-converting enzyme (ACE) inhibitor and a platelet-aggregation inhibitor. Camostat mesilate, 600 mg/day, orally, caused a marked decrease in urinary protein excretion after the 7th consecutive day of drug administration. There were no serious adverse effects. Its mechanism of action in this respect is not known. Camostat mesilate thus merits clinical trials in the treatment of nephrotic syndrome related to diabetic nephropathy.- - - - - - - - - - ranking = 7keywords = nephropathy (Clic here for more details about this article) |
3/188. Membranous nephropathy associated with childhood sarcoidosis.sarcoidosis is a chronic multisystemic granulomatous disease of unknown etiology. It is relatively rare in children. Renal involvement in sarcoidosis is described less commonly than other organ involvement such as pulmonary, eye, musculoskeletal, and skin. We report a 13-year-old girl with sarcoidosis and nephrotic syndrome. Renal biopsy showed findings of membranous nephropathy. She received intravenous pulse methylprednisolone and oral cyclophosphamide with resolution of the symptoms of fever and edema, and improvement of the proteinuria. Her condition is stable with no progression of her renal disease. To the best of our knowledge, this is the first report of membranous nephropathy associated with childhood sarcoidosis.- - - - - - - - - - ranking = 6keywords = nephropathy (Clic here for more details about this article) |
4/188. nephrotic syndrome and acute interstitial nephritis associated with the use of diclofenac.Commonly reported renal complications of non-steroidal anti-inflammatory drugs (NSAID) include acute renal failure and/or acute interstitial nephritis; in rare cases a nephrotic syndrome was also observed. In most cases this was due to the development of secondary membranous nephropathy. Following withdrawal of the drug the nephrotic syndrome usually resolved rapidly. We report a 65-year-old woman who developed a nephrotic syndrome and acute renal failure during 6 months of treatment with the NSAID diclofenac. Renal biopsy revealed both, membranous nephropathy and interstitial nephritis. After discontinuation of diclofenac and treatment with prednisone 1 mg/kg/day, furosemide 400 mg/day and simvastatin at a dose of 20 mg/day, creatinine clearance gradually increased and after 5 months of treatment complete remission of the nephrotic syndrome was observed.- - - - - - - - - - ranking = 2keywords = nephropathy (Clic here for more details about this article) |
5/188. Effectiveness of radiation therapy in nephrotic syndrome associated with advanced lung cancer.Paraneoplastic nephrotic syndrome is rare, bur occurs mostly in lung cancer. The glomerular lesion usually exhibits membranous nephropathy. Although surgical therapy has been shown to be effective, the treatment of a paraneoplastic nephrotic syndrome has always been a challenge. Currently no standard therapy has been established, if the paraneoplastic nephrotic syndrome is associated with advanced cancer with unresectable lesions. We present 2 cases having paraneoplastic nephrotic syndrome associated with advanced squamous cell carcinoma of the lung. radiation therapy of the primary tumor effectively caused regression of the paraneoplastic nephrotic syndrome without affecting the renal function. Our results suggest that irradiation can be the first choice in the treatment of nephrotic syndrome, if the primary tumor is unresectable.- - - - - - - - - - ranking = 1keywords = nephropathy (Clic here for more details about this article) |
6/188. Resolution of HIV-associated nephrotic syndrome with highly active antiretroviral therapy delivered by gastrostomy tube.There is no consensus regarding the specific management of HIV-associated nephrotic syndrome. We report a child whose first manifestation of human immunodeficiency virus type 1 (hiv-1) infection was nephropathy and wasting syndrome associated with profound immunodeficiency. The patient had a dramatic clinical and immunologic response to triple antiretroviral therapy delivered through a gastrostomy tube, with complete resolution of nephrotic syndrome. A 51/2-year-old African-American girl presented with a 2-week history of cough, chest pain, vomiting, loose stools, abdominal distention, anorexia, and fever. In addition, she had recurrent oral thrush. Her weight and height were below the 5th percentile. She was chronically ill, appearing with oropharyngeal thrush and pitting edema in lower extremities. She had scattered rhonchi and decreased breath sounds on both lung bases. Her abdomen was distended and diffusely tender. A chest radiograph showed consolidation of the right upper and left lower lobes with bilateral pleural effusion. Admission laboratories were consistent with nephrotic syndrome. streptococcus pneumoniae grew from the blood culture and the child responded well to treatment with intravenous ceftriaxone. She was found to be HIV-infected, her CD4( ) cell count was 3 cells/mcL and her plasma hiv-1 rna was >750 000 copies/mL. A percutaneous gastrostomy tube was placed for supplemental nutrition. She was treated with stavudine, lamivudine, and nelfinavir via gastrostomy tube with good clinical response. Twenty-one months after instituting antiretroviral therapy, her weight and height had increased to the 50th and 10th percentile respectively, and she had complete resolution of her nephrotic syndrome. Her CD4( ) cell count increased to 1116 cells/mcL and her viral load has remained undetectable. hiv-1 associated nephrotic syndrome has been described in children with profound immunodeficiency. The course of untreated HIV-associated nephrotic syndrome is rapid progression to renal failure in up to 40% of the children. Regardless of the presence of renal insufficiency, if untreated, it is uniformly fatal. A modest improvement of hiv-1 associated nephrotic syndrome has been observed in patients treated with zidovudine. Steroid and cyclosporine treatment have resulted in improved renal function but long-term use of immunosuppressive therapy has raised concerns about safety. We have described, to our knowledge, the first child with HIV-associated nephrotic syndrome who had a remarkable clinical, immunologic, and virologic response to triple-drug combination therapy given by gastrostomy tube, with complete resolution of proteinuria and normalization of the serum albumin. She also had a striking improvement in weight, height, and quality-of-life. Whether the presence of a gastrostomy tube contributed to the excellent response because of improved compliance is unknown, but warrants systematic evaluation.- - - - - - - - - - ranking = 1keywords = nephropathy (Clic here for more details about this article) |
7/188. nail-patella syndrome and IgA nephropathy in a Chinese woman.nail-patella syndrome (NPS), also known as hereditary onycho-osteodysplasia, is an autosomal dominant pleiotropic disorder characterized by nailbed dysplasia or hypoplasia, absent or hypoplastic patellae, iliac horns and deformation or luxation of the radial head. Nephropathy is a known serious complication associated with NPS. In this report, we describe an adult Chinese woman with the clinical and radiological features of NPS who presented with the nephrotic syndrome. Renal biopsy disclosed focal segmental glomerulosclerosis on light microscopy, while immunofluorescence revealed predominant staining for IgA in the glomerular mesangium and along some capillary walls. Ultrastructural study confirmed the presence of paramesangial deposits as well as subendothelial collagen fibrils in the glomeruli. The histological findings were those of combined NPS and IgA disease, an association which has rarely been described.- - - - - - - - - - ranking = 4keywords = nephropathy (Clic here for more details about this article) |
8/188. Pleural mesothelioma and membranous nephropathy.Underlying malignancy has been thought to be responsible for 5-10% of the cases of membranous nephropathy in adults, with the risk being highest in patients over the age of 60 years. Solid tumors such as carcinomas of lung or colon, are most often involved. It is presumed that tumor antigens are deposited in the glomeruli; this is followed by antibody deposition and complement activation, leading to epithelial cell and basement membrane injury and proteinuria due to the associated increase in glomerular permeability. We describe a patient with a resistant nephrotic syndrome and massive proteinuria due to membranous nephropathy associated with pleural mesothelioma.- - - - - - - - - - ranking = 6keywords = nephropathy (Clic here for more details about this article) |
9/188. nephrotic syndrome due to membranous nephropathy associated with metastatic prostate cancer: rapid remission after initial endocrine therapy.A case of severe nephrotic syndrome (urinary protein excretion 12.9 g/day) due to membranous nephropathy associated with untreated prostate cancer and multiple bone metastases is described. A combination of initial endocrine treatment and steroid therapy resulted in normalization of prostate-specific antigen levels followed by a rapid decrease of urinary protein excretion within 4 months. No proteinuria was subsequently detected. Seven months after the initiation of therapy, the patient remained well with complete clinical remission from the nephrotic syndrome. This rapid achievement of remission may have been due to tumor shrinkage by androgen ablation in addition to steroid therapy of the membranous nephropathy. The nephrotic syndrome is a rare complication of prostate cancer, and, to the best of our knowledge, no previous cases have been reported of membranous nephropathy as one of the first disease manifestations.- - - - - - - - - - ranking = 7keywords = nephropathy (Clic here for more details about this article) |
10/188. Diabetic nephropathy accompanied by iodine-induced non-autoimmune primary hypothyroidism: two case reports.We reported 2 diabetic patients with nephrotic syndrome due to advanced diabetic nephropathy complicated by non-autoimmune primary hypothyroidism. hypothyroidism developed along with the anasarcous status. Histological examinations of the thyroid gland revealed almost normal thyroid follicles without lymphocytic infiltration. The amounts of thyroid hormone lost into the extravascular space such as in urine and ascites were not sufficient to cause hypothyroidism alone. Serum total iodine levels measured during the hypothyroidal state in both cases were definitely elevated, and the perchlorate discharge test of both cases showed positive discharge (24 and 34%, respectively). The thyroid functions normalized after iodine restriction in the first case and initiating hemodialysis in the second case, in parallel with normalization of serum total iodine levels. These findings suggest that impaired renal handling of iodine resulting in elevation of serum iodine levels, rather than an autoimmune mechanism or extravascular hormone loss, played a principal role in the development of primary hypothyroidism found in these 2 patients, probably through a prolonged Wolff-Chaikoff effect.- - - - - - - - - - ranking = 5keywords = nephropathy (Clic here for more details about this article) |
