Urinary investigations
Problem no. 1
What is your diagnosis?
My diagnosis is nephrotic syndrome.

What are the positive points behind your diagnosis?
1. Typical onset of nephrotic syndrome: 2-6 years of life
2. Nephrotic range of proteinuria (4+)
3. Presence of lipid cast suggests hyperlipidemia
4. Absence of hematuria (exclude nephritic syndrome).
What do you mean by nephrotic range of proteinuria?
Any 1 of the following:
1. 24 hour urinary protein excretion: >2 gm/ 24 hours
2. Spot urine protein: creatinine ratio: >2.0
3. Total urine protein (according to body surface area) : >40 mg/sq.mt/hr.
What are the further investigations you will prefer to order?
1. 24 hour urinary protein excretion
2. Spot urine protein: creatinine ratio
3. Blood examination:
a. Hypercholesterolemia: >200 mg/dL
b. Hypoalbuminemia: <2.5 mg/dL.
4. Renal function test: Usually renal function remains normal in minimal change NS,
significant rise in serum urea-creatinine suggests a decrease in renal perfusion
and hypovolemia.
5. Chest X Ray and Mantoux test (to exclude renal tuberculosis)
6. HIV/ HBV testing.
Outline the management of the case (1st episode of NS).
General management:
High protein diet
Dietary salt and fluid restriction
Diuretics (Furosemide) should be used only in case of significant edema.
Specific management:
Agent of choice: Corticosteroid (Prednisolone/ Prednisone)
2 mg/kg/day (maximum 60 mg/day) in 2-3 divided doses for a duration of
6 weeks.
