Focal Segmental Glomerulosclerosis

Focal segmental glomerulosclerosis comprises 10% of childhood and 15-20% of cases of adult idiopathic nephrotic syndrome. Patients present with proteinuria
and microscopic hematuria. Hypertension is also common. 

The pathogenesis of the sclerosing lesions and their progressive nature are debated. Humans with idiopathic focal segmental glomerulosclerosis initially have a high glomerular filtration rate and evidence of hyperfiltration, suggesting that hyperfiltration and increased intracapillary glomerular pressure may be mediators of this disease. A similar pattern of segmental sclerosis may be seen in a number of distinct glomerular diseases with different pathogenetic mechanisms and clinical courses (eg. IgA nephropathy). 
 
Clinical Course

Focal segmental glomerulosclerosis may be primary (idiopathic) or secondary to a number of etiologic agents including: 

 Unilateral renal agenesis 
 Renal ablation 
 Sickle cell disease 
 Morbid obesity (with or without sleep apnea) 
 Congenital cyanotic heart disease 
 Heroin nephropathy 
 HIV nephropathy 
 Aging kidney 

Steroid therapy may induce remission in 20-40% of children and fewer adults. Adults progress to renal failure rapidly over 2-3 years (15-20%) or more slowly over 10-12 years. Focal segmental glomerulosclerosis commonly recurs following transplantation (50-80%).

i was diagnosed with mpgn type 2 at 4 yrs old... it all started with a persistant cold. My mom always thought i was pale but, she had no idea until she found me lethargic on the floor.. my blood pressure was sky high. my urine was black. my 14 yr treatment consisted of aggressive doses of prednisone and blood pressure medication. i also give all the credit in the world to the doctors and staff at the Motts childrens hospital in ann arbor michigan.
