nephrotic syndrome
Let an agent explain nephrotic syndrome and its causes in general terms from nephrology guidelines, describe diagnosis and treatment approaches, distinguish it from nephritic syndrome, and route personal questions to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain nephrotic syndrome and its causes in general terms from nephrology guidelines, describe diagnosis and treatment approaches, distinguish it from nephritic syndrome, and route personal questions to clinicians.
A kidney disorder in which damage to the glomerular filter causes heavy loss of protein into the urine, low blood albumin, swelling and high blood lipids, arising from primary glomerular diseases such as minimal change disease, focal segmental glomerulosclerosis and membranous nephropathy, from proliferative and membranoproliferative glomerulonephritis, and from systemic conditions such as diabetes and lupus, with rare genetic forms sometimes accompanied by ocular anomalies; nephrotic syndrome is treated with steroids, immunosuppression and supportive care according to cause.
What it is for: Not applicable; a clinical syndrome.
It can be explain the syndrome and causes; relay diagnosis and treatment approaches; distinguish from nephritic syndrome; route personal questions.
Distinguishing features
Glomerular protein leak
Oedema and hypoalbuminaemia
Primary and secondary causes
Steroid responsiveness in many children
What it looks like
Not a visible object; swelling and frothy urine are typical signs.
Physical character
proteinuria threshold: over 3.5 g per day - adults
childhood incidence: about 2-7 per 100000 per year
How it is recognised
Heavy proteinuria with low albumin and oedema
Minimal change, FSGS, membranous, proliferative and systemic causes
Nephritic syndrome features blood in urine and hypertension; chronic kidney disease is the broader decline

- The registry entry has merged aliases naming histological lesions and rare syndromes; should they be split off?
