==[[Minimal change disease overview|Overview]]==


'''Minimal change disease''' or ''nil disease'' (lipoid nephrosis) is a disease of the [[kidney]] which causes [[nephrotic syndrome]] and usually affects children (peak incidence at 2-3 years of age).<ref name=Robbins_2005>{{cite book | author = Kumar V, Fausto N, Abbas A (editors) | title = Robbins & Cotran Pathologic Basis of Disease | edition = 7th | pages=pp. 981-2 | publisher = Saunders | year = 2003 | id = ISBN 978-0-721-60187-8 }}</ref>

==Symptoms==
==[[Minimal change disease classification|Classification]]==
The symptoms are [[proteinuria]] (leakage of protein into the urine) and [[water retention]].  There are other kidney diseases that have these same symptoms but a [[needle biopsy]] shows change in the kidney tissue if these other diseases are present. 


==Causes==
==[[Minimal change disease pathophysiology|Pathophysiology]]==
Minimal change disease can be associated with food allergies, medications, or hematologic malignancies, or it can occur [[idiopathic|idiopathically]]. The pathology does not appear to involve complement, [[Antibody|immunoglobulins]], or immune complex deposition. Rather, an altered cell-mediated immunologic response with abnormal secretion of [[lymphokine]]s by [[T cell]]s is thought to reduce the production of anions in the [[glomerular basement membrane]], thereby increasing the glomerular permeability to [[serum albumin]] through a reduction of electrostatic repulsion.<ref name=Mathieson_2003>{{cite journal |author=Mathieson P |title=Immune dysregulation in minimal change nephropathy |journal=Nephrol Dial Transplant |volume=18 Suppl 6 |issue= |pages=vi26-9 |year=2003 |pmid=12953038}}</ref> The loss of [[Anion|anionic]] charges is also thought to favor foot process fusion.  With minimal change disease the kidney tissue appears normal under a light microscope, but shows [[podocyte]] foot process effacement under an [[Electron microscopy|electron microscope]].<ref name=Robbins_2005 />


==Treatment==
==[[Minimal change disease causes|Causes]]==
[[Prednisone]] is prescribed along with a blood pressure medication, typically an [[ACE inhibitor]] such as [[lisinopril]].  Often the liver is overactive with minimal change disease and over produces [[cholesterol]].  Therefore a [[statin]] drug is often prescribed for the duration of the treatment.  When the urine is clear of protein, the drugs can be discontinued. 50% of patients will relapse and need further treatment.

==Other notes==
==Diagnosis==
80% of those who get minimal change disease have a recurrence with 20% never realizing another occurrence.  Some authors have noted that other conditions associated with T-cell abnormalities, such as [[Hodgkin's disease]] and [[T-cell lymphoma]], are sometimes associated with minimal change disease.
