Nephrotic Syndrome Vs Nephritic

Syndrome

Dr. T.S. Srinath Kumar MD Group Head, Narayana Hrudayalaya President, Society Emergency Medicine India Member - Special Advisory Board for Emergency Medicine, DNB Associate Editor – National Journal of Emergency Medicine

  • 24 year old male was brought to ED with polytrauma Has dark colored urine on catheterisation

Fluid status assessment

  • IVC/Ao Index around 1.2 +- 0.

Objectives

 Understand and define nephrotic and nephritic syndromes.  Describe the initial investigations and management of nephrotic and nephritic syndromes.  Describe the complications of nephrotic and nephritic syndromes.

Pathophysiology

NEPHROTIC

  • Loss of foot processes NEPHRITIC
    • Proliferative changes and inflammation of the glomeruli Bottom line- “increased permeability of the glomeruli”

Nephrotic Syndrome

Proteinuria

3gm/day Hypoalbuminemia <2.5gm/dl Hyperlipidemia

Edema Nephrotic

Syndrome

Further possible presentations...

 Oedema  BP normal/raised  Leukonychia  Breathlessness:  Pleural effusion, fluid overload, AKI  DVT/PE/MI  Eruptive xanthomata/ xanthalosmata

Possible Scenarios ...

 Young, fit 24 year old male complaining of frothy urine.  10 year old boy with puffy eyes.  74 year old female with multiple co-morbidities and swollen ankles.

Causes of Nephrotic

Syndrome

 Primary glomerulonephritis  Minimal change disease (80% paeds cases)  Focal segmental glomerulosclerosis (most common cause in adults)  Membranous glomerulonephritis

Systemic Causes

 Secondary glomerulonephritis  Diabetic nephropathy  Sarcoidosis  Autoimmune: SLE, Sjogrens  Infection: Syphilis, hepatitis B, HIV  Amyloidosis  Multiple myeloma  Vasculitis  Cancer  Drugs: gold, penicillamine, captopril, NSAIDs

Management

Conservative  Monitor U&E, BP, fluid balance, weight  Salt and fluid restriction  Treat underlying cause

Management

Decrease Glomerular pressure Contain antifibrotic effects For controlling edema Combination drugs more useful For Hyperlipidemia and Hyper triglyceredemia
