Etiology:

Most common is DM. Others are HTN/RAS, glomerular, interstitial , drugs, congenital, myeloma and PKD.

Evaluation:

-Evaluate for uremic symptoms and signs
GeneralNausea, weight loss, hypothermia
SkinPruritus, calciphylaxis(skin ulcers)
Metabolicincreased K and phosphorus, decreased Ca, 2 PTH, acidosis
CardioHTN, CHF, LVH, pericarditis
Neuroseizures, neuropathy. decreased memory/attention/MS (encephalopathy)
HemeAnemia, bleeding(plt dysfunction)

Management:

-Consult Nephrology if proteinuria or GRF <30. BP measurements, IVs for dialysis access planning. -Restrict sodium, potassium, phosphorus and protein intake especially if HTN or hyperkalemic. -Treat/ risk reduction of co-morbidities (DM, HTN, CAD) with glucose control/ SGLTi, statin, ACEi/ARB ( reassess Cr and d/c if there is a 30% increase post ACEi/ARB). -Sevelamer to control phosphorus levels, HCO3 replete if acidotic, Fe supplementation for anemia (goal Hb 10-11.5). -Evaluate for transplant (GFR <20)
