1/65. mannitol and frusemide in the treatment of diuretic resistant oedema in nephrotic syndrome.Three children (two girls aged 7 and 9 years, and one boy aged 4 years) with diuretic resistant oedema in steroid resistant nephrotic syndrome were treated with a combination of intravenous mannitol and frusemide. All three responded with loss of oedema of 10% to 30% of body weight over one week. There were no complications of hypertension or hypovolaemia. mannitol-frusemide combination is a safe, inexpensive, and effective treatment for diuretic resistant oedema. Its use in other conditions and in developing countries (where the availability and purity of 20% albumin is limited) needs to be explored.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
2/65. Cerebral venous thrombosis in patients with nephrotic syndrome--case reports.The authors describe two cases of cerebral venous thrombosis (CVT) in patients with nephrotic syndrome. The main clinical features of CVT were persistent headache, hemiparesis, and seizure, and the diagnosis was based on magnetic resonance imaging and magnetic resonance angiography. Both showed acquired deficiency of free protein s. The neurologic symptoms remained stationary in the first patient, who received no anticoagulation therapy, but resolved rapidly in the second, treated with intravenous heparin and supplemented with fresh frozen plasma. CVT should be suspected in patients with nephrotic syndrome who present with symptoms of intracranial hypertension or any focal neurologic deficit.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
3/65. Primary antiphospholipid syndrome presented by total infarction of right kidney with nephrotic syndrome.We report the case of a young woman with primary antiphospholipid syndrome (APS), which presented with acute renal failure, hypoproteinemia, hypoalbuminemia and nephrotic proteinuria. Investigations showed total infarction of right kidney by extensive arterial and vein thrombosis and presence of anticardiolipin antibodies IgG isotype (anti-beta2-glycoprotein I-positive). She was submitted to right nefrectomy and initiated anticoagulant therapy. After nefrectomy, the postoperative period was marked by the development of arterial hypertension and persistence of nephrotic syndrome. Hypertension was treated with antihypertensive drugs (IECA, beta-blocker and calcium antagonist). As the nephrotic syndrome persisted despite anticoagulant and antihypertensive therapy, the patient was treated with oral corticosteroids. Her renal function improved, hypoproteinemia and hypoalbuminemia corrected to normal values and proteinuria decreased to subnephrotic value. We discuss the unusual presentation of this case of primary antiphospholipid syndrome with total unilateral renal thrombosis and nephrotic syndrome that respond to anticoagulant, antihypertensive and corticosteroid therapy.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
4/65. Fibrillary-immunotactoid glomerulopathy with renal deposits of IgAlambda: a rare cause of glomerulonephritis.We describe a 24-year-old patient who presented with a nephrotic syndrome. His renal biopsy revealed a diffuse mesangioproliferative glomerulonephritis with eosinophilic deposits. Electron microscopy showed organized, congo-red negative deposits, forming microtubules of about 20 nm width in the capillary walls and in the mesangium, establishing a diagnosis of fibrillary-immunotactoid glomerulopathy. Fibrillary-immunotactoid glomerulopathy is a rare cause of glomerulonephritis, characterized by congo-red-negative glomerular deposits of fibrils, sometimes organized in microtubules, predominantly containing IgG and C3. patients clinically present with the nephrotic syndrome, hematuria and hypertension. The pathogenesis of this glomerulopathy has not been elucidated yet. In our patient, the renal deposits contained IgAlambda. This peculiar feature is suggestive of an underlying paraproteinemia. However, in the serum no paraproteins or cryoglobulins were found, and also microscopical examination and immunophenotyping of the bone marrow did not point to the presence of a monoclonal plasma cell dyscrasia. Our patient was not treated with immunosuppressive drugs and he is currently progressing to end-stage renal disease.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
5/65. nephrotic syndrome secondary to amyloidosis.nephrotic syndrome represents a constellation of symptoms including hyperalbuminuria, hypoalbuminemia, edema formation, hypercholesterolemia, hypertension, hypercoagulopathy, and increased infection risk. The hallmark of this syndrome is proteinuria greater than 3.5 grams per 24 hours, and the clinical features are secondary manifestations of an underlying primary glomerular or systemic disease. The objectives of treatment are threefold: correcting the primary disease, decreasing the symptoms and secondary effects associated with this syndrome, and preventing complications. This article presents a case report of a man diagnosed with nephrotic syndrome secondary to amyloidosis. The clinical aspects of the disease processes, the diagnostic evaluation, the treatment course, and disease management are discussed.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
6/65. Role of lipids in the progression of renal disease in systemic lupus erythematosus patients.Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disease marked by immune-complex mediated lesions in small blood vessels of various organs, especially the kidneys, although other factors may also be implicated in the pathogenesis of the disease. This article focuses on the role of lipids in the progression of glomerular, vascular and tubulo-interstitial lesions in two patients with lupus nephritis associated with pronounced hyper- and dyslipidemia. The pathogenesis of progressive glomerulosclerosis in both patients appears to be multifactorial. In addition to immune complex mediated lupus glomerulonephritis, progressively active in the first patient, severe nephrotic-range persistent proteinuria, arterial hypertension associated with hyperfiltration and hyperperfusion injuries and, to a minor extent, hyper- and dyslipidemia were observed. Immunological and non-immunological factors were shown to contribute to the development of tubulo-interstitial lesions. In both patients, in addition to local immune deposits, prominent tubulo-interstitial lipid deposits were probably causally related to both hyperlipidemia and the increased permeability of the glomerular filtration barrier. Tubular lesions were highlighted by intracytoplasmic lipid droplets as well as small cleft-like spaces found to be impacted in the tubular lumina. They were seen to penetrate tubular epithelial cells and eventually lodge in the interstitium, surrounded by mononuclear cell infiltrates and foam cells. In both patients, hypertensive angiopathy and extraglomerular vascular immune deposits were demonstrated. In addition, in the second patient, arteriolar and small arterial hyaline was found at the age of 28 years to be full of lipids and calcium precipitates, suggesting a peripheral atherosclerosis-like process which never occurs as a natural age-related condition. In conclusion, all parts of the nephron may be involved in the pathogenetic process causally related or influenced by hyper- or dyslipidemia. Associated either with endothelial cell injury and consequent insudation of lipids in the vascular walls, glomerular filtration barrier injury with hyperfiltration, or tubulo-interstitial lipid deposition, the mechanism of tissue damage by lipids in all parts of the nephron shares similarities with the pathogenesis of systemic atherosclerosis.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
7/65. moyamoya disease complicated with renal artery stenosis and nephrotic syndrome: reversal of nephrotic syndrome after nephrectomy.A 7-year-old boy with moyamoya disease developed sustained hypertension, nephrotic syndrome, hyperreninemia, and occlusion of the right renal artery. After right nephrectomy, hyperreninemia and hypertension improved. proteinuria was resolved after nephrectomy, in parallel with the decrease in plasma renin activity. moyamoya disease can cause nephrotic-range proteinuria, which is caused hemodynamically by hyperreninemia.- - - - - - - - - - ranking = 2keywords = hypertension (Clic here for more details about this article) |
8/65. Spontaneous remission of the nephrotic syndrome in diabetic nephropathy.A 28 year old woman, with diabetes since age 18, had the nephrotic syndrome, hypertension and renal insufficiency. The initial renal biopsy specimen revealed diffuse glomerulosclerosis with early nodular changes. After an initial decline in renal function, her creatinine clearance progressively improved and has remained normal. Within 2 years she had a spontaneous remission of the nephrotic syndrome despite the presence of more pronounced nodular glomerular lesions. Although the renal hemodynamic functions were normal, certain tubular functions were impaired. Since we found no etiology for the nephrotic syndrome other than diabetic glomerulopathy, the complete remission of the nephrotic syndrome and improvement in renal function were very unusual events.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
9/65. Management of steroid-sensitive nephrotic syndrome in children with type 1 diabetes.Four children with steroid-sensitive nephrotic syndrome (SSNS) coexisting with type 1 diabetes are presented. This number is higher than expected according to the estimated prevalence rates for each disease separately. In three, diabetes preceded nephrotic syndrome (NS), and in one it developed almost simultaneously. None of the patients had hypertension or retinopathy. Two had a renal biopsy: in one it was compatible with minimal change histology (MCH), and the other had MCH and early diabetic nephropathy changes. In addition to the two presented here, in 11 of 12 previously reported cases with biopsy proven SSNS coexisting with type 1 diabetes, the biopsy showed MCH. In none was treatment influenced by biopsy results. However, our experience suggests that daily steroid taper allows easier glycaemic control than alternate day steroids. We conclude that the indications for a renal biopsy in nephrotic children with and without insulin-dependent diabetes mellitus (IDDM) should be similar.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
10/65. Fibronectin glomerulopathy with nephrotic syndrome in a 3-year-old male.Familial non-immune-mediated glomerulopathy has recently been recognized as a distinct clinical entity. The presentation includes proteinuria, often in the nephrotic range, microscopic hematuria, and hypertension. Renal function may remain intact long term, or may progress slowly to renal failure. A 3-year-old boy was referred with proteinuria (>8 g/day), microscopic hematuria, and hypertension (184/150 mmHg). Renal function was intact. Diagnostic evaluation uncovered no evidence of systemic disease. A renal biopsy specimen showed no immune deposits in the glomeruli, but fibronectin deposits were detected in the peripheral loop and mesangium by immunofluorescence. The basement membrane was intact. Twelve other family members subsequently were found to have some renal pathology. Renal function was preserved during 7 years of follow-up. The pathogenesis of fibronectin glomerulopathy is discussed.- - - - - - - - - - ranking = 2keywords = hypertension (Clic here for more details about this article) |
