1
Q

Common complications (2) of ESRD patients despite EPO therapy that leads to fatigue and tiredness?

A
  1. Iron Deficiency Anemia due to blood loss (multiple blood draws.)
    EPO therapy (causes high mobilization to build more RBCs)

Q

80 y old woman presents with Fatigue, Dizzy spells, and Nausea. Pt was recently started on Thiazide Diuretic for Hypertension. Dx? Rx?

A

Thiazide Induced Hyponatremia
-Causes Increase Na+ Excretion and Increase ADH ( Leads to Water retention unlike Loop Diuretics that Do Not Cause Water Retention)

Check Na+ Level, Stop Thiazide and Give Normal Saline.

Q

Young women reports recurrent UTIs and decreased GFR. Urine pH is 8. Dx? Rx?

A

Stone Removal for Struvite Stone + Abx ( only way to eradicate the bacteria and restore kidney function). The struvite stone can lead to staghorn calculi caused by E. Coli and Proteus.

Q
  1. What is the Serum Anion Gap?
  2. What is the Urine Anion Gap?
  3. What is the osmolar gap>

2. What is the Urine Anion Gap?

A

1.) Na - ( CL + HCO3 )
2.) Na + K- CL ( Urine Anion- Urine Cation)
Inability of the Kidney to excrete Acid because the kidney cannot Generate enough ammonium to excrete Acid = Renal Tubular Acidosis ( the Urine Anion Gap is Positive)
Negative Urine Anion Gap = A lot of Ammonium is Generated by a normal Kidney to help excrete Acid ( after eating Animal Protein) Also present in GI loss. Lose HC03.

  1. 2 (Na) + Bun/2.8 + Glucose/18
17
Q

42 yo W presents with Recurring Red Spots on her legs for 2-3 years. Also reports Occasional Abdominal pain, Arthralgias. She has 2+ Protein, RBC 10-120 and Occasional red blood cell cast. Dx? Test? Rx?

A

Henoch Schonlein Purpura.

IgA immune complex deposits in small vessels on skin biopsy. It is a leukoclastic vasculitis.

18
Q

Man presents with Abdominal pain, progressive Fatigue, LE edema and chronic cough. CXR shows Cardiomegaly with Small effusions. UA protein is 1+ but Spot Urine Total Protein/Creatinine ratio is 2.5. Dx?

A

Multiple Myeloma.

There will be discrepancy on the dipstick (only picks up Albumin and not light chains) vs the qualitative analysis.

19
Q

Name The Effects of Calcium stone prevention:

  1. Decrease Sodium Intake?
  2. Increase Calcium Intake?
  3. Increase Fluid Intake
  4. Increase Fruit and Vegetable Intake?
  5. Decrease Animal Protein?
A
  1. Decreases Calcium Excretion and increases Sodium and Calcium Proximal Tubule Reabsorption
  2. Calcium Binds to Oxalate in Gut which Decreases Urinary Calcium and Oxalate Excretion. Oxalate wont be reasorb in the blood stream going to the kidney to form calcium oxalate stones.
  3. Increase Urine flow and Decreases Solute Concentration
  4. Increase Citrate Excretion, Citrate binds to Urinary Calcium to inhibit Stone formation (Lemon Juice)
  5. Decreases Acid load and Urinary Calcium Excretion, Decrease Uric Acid Excretion.
20
Q

22 yo M (Young Patient) presents with 7mm Kidney stone. UA shows occasional hexagonal crystals with benzene ring morphology. Dx? Rx?

A
  1. Cystine Stone.

Increase fluid and .2 Alkalinize Urine. (potassium citrate or bicarbonate.)

21
Q

Name the Stone:
Risk Factors:
1. Hyperparathyrodism (hypercalciuria), Malabsorption (hyperoxaluria), Distal RTA (hypocitraturia).

  1. What will the UA show?
A
  1. Calcium oxalate.
  2. Enveloped shape crystals
22
Q

Name the Stone:

  1. Risk Factors: Gout, Myeloproliferative disorders
  2. What will the UA show?
A
  1. Uric Acid Stones

2. Rhomboid Crystals, Radiolucent stones

23
Q

Name the Stone:

  1. Risk Factors: Decrease reabsorption of cystine in Kidney?
  2. What will the UA show?
A
  1. Cystine Stone.

Hexagonal green/yellow crystals, Large branched calculi
