Tx- Fomepizole
Which type of AGMA can cause blindness and papilledema?

If osmolol gap is greater than 20?
What if osmolol gap is greater than 50?
Give Fomepizole
Hemodialysis
Tx Type 2 RTA
Thiazides and alkali depletion
Problem with proximal CT, can’t reabsorb bicarbonate or NaCl
Looks like Fanconi Syndrome
Tx Type 1 RTA
Give potassium citrate
Distal CT can’t acidfy urine, urine pH > 6 and hypocitaturia
Features of type 4 RTA
Aldosterone deficiency or resistance causing hyperkalemia
Tx- try fludrocortisone
Features of Barter’s syndrome
Like loop diuretic
Hypokalemia, low BP, urine Cl > 15
Tx- inhibit prostaglandin production with indomethacin and ibuprofen
Features of Gitelman syndrome
Like thiazides
Problem with DCT sodium receptor
Hypokalemia, low BP, urine Cl > 15
Uric acid
Salicylate overdose causes…?
Respiratory alkalosis followed by metabolic acidosis
Features of Liddles Syndrome
Increased transport defect in distal tubule causing hyperaldosteronism
High BP
If you see hyponatremia and urine sodium
Hepatorenal syndrome
Lab findings in SIADH
Low serum sodium
High urine sodium
High urine osmolarity
Tx: demeclocycline or tolvaptan
(Demeclocycline in CI in liver cirrhosis)
How to fix it when you overcorrect hyponatremia?
Desmopressin with Dextrose 5%
