minimal change disease (mcd) is the leading cause of childhood nephrotic syndrome (ns). therefore in pediatrics nephrotic syndrome, most children beyond the first year of life will be treated with corticosteroids without an initial biopsy. children with ns often display a number of calcium homeostasis disturbances causing abnormal bone histology, including hypocalcemia, reduced serum vitamin d ...

The patient was an 18-year-old man who developed nephrotic syndrome after a 'wheat spider' bite (Latrodectus mactans). Due to this atypical manifestation of latrodectism, a renal biopsy was performed showing minimal change disease. The nephrotic syndrome subsided after 1 week without specific treatment. This self-limited evolution suggests that the mechanism of podocyte damage was temporary and...

Nephrotic syndrome is a common glomerular disease in children with significant variability in both incidence and steroid responsiveness among various ethnic groups. The average incidence of nephrotic syndrome is 2-16.9 per 100,000 children worldwide [3] . In adults, diabetes mellitus is the most common secondary cause and focal segmental glomerulosclerosis and membranous nephropathy are the mos...

In July 1994, a 70-year-old woman was diagnosed as having nephrotic syndrome with proteinuria of 8 to 10 g/day and a serum albumin level of 1.8 g/dl. She was hospitalized in August 1994 for investigation. The urinary findings then normalized, with urinary protein and occult blood both negative and total urinary protein excretion at 0 g/day. A renal biopsy was performed, and spontaneous remissio...

Minimal change nephropathy (MCNS) and focal segmental glomerulosclerosis (FSGS) are the main causes of the idiopathic nephrotic syndrome. MCNS usually responds to steroids and the long-term prognosis is generally good. However, some patients require prolonged treatment with immunosuppressive agents. FSGS generally follows a less favourable course: patients do not always respond to steroids and ...

INTRODUCTION Paraneoplastic glomerulopathies are rare manifestations of neoplastic disease to be distinguished from iatrogenic renal damage. Solid tumors are preferentially associated with membranous nephropathy, whereas Hodgkin's lymphomas are associated with minimal change disease. CASE PRESENTATION We report a 63-year-old Caucasian male diagnosed with a mesothelioma of the tunica vaginalis...

Idiopathic nephrotic syndrome (INS) in children is most commonly caused by primary glomerulopathies. Morphological lesions observed in INS might be secondary to inflammatory factors of mainly extra-renal origin. The vascular endothelial growth factor (VEGF) family is regarded as playing a crucial role in this pathomechanism. The aim of the present work was to analyze the possible relation betwe...

The use of cyclosporin A (Cy A) in idiopathic nephrotic syndrome, particularly lesions of focal segmental glomerular sclerosis, is controversial. A retrospective study of 10 adult patients with nephrotic syndrome treated with Cy A was performed. Histological diagnosis was established in all patients: focal segmental glomerular sclerosis (n = 6), focal global sclerosis (n = 1), mesangial prolife...
