Q

What is the Loop of Henle?

A

Descending limb (down): water is reabsorb

Ascending limb (up): Na and Cl ions are reabsorb

*If antidiuretic hormone (ADH) or Vasopressin is present water passes through the walls of the ascending limb and is reabsorbed into the blood; less water excreted in the urine (anti-diuresis)

Q

Loop of Henle and Diuretics?

A

Loop diuretic inhibit the Na-K pump in the ascending limb ; less Na and Ca is reabsorb back into the blood.

Long term Ca depletion can decrease bone density.

Na concentration increase in filterate , less water is reabsorb and both are excreted in the urine.

Q

Distal convoluted tubule and Diuretics?

A

Thiazides( 5% Na reabsorb) is a weaker diuretic than loops (25% Na reabsorb).

Thiazides increases Ca reabsorption therefore long-term use has protective effect on bone.

Q

Aldosterone role in distal convoluted tubule and collecting ducts?

A

Works in the tubule and duct to increase Na and water reabsorption but decrease K reabsorption.

Aldosterone Antagonist ( Spironolactone and Eplerenone) block aldosterone; more Na and water is excreted in the urine but serum K increases.

Q

Reasons to MODIFY DRUG THERAPY in CKD

A

Drug is Eliminated through the Kidneys: modify to avoid accumulation and SE/toxicity; Reduce dose and/or extend interval

The drug can cause or worsen kidney disease( Nephrotoxic)

Drug become less effective as kidney function declines (ex. Thiazide, and Nitrofurantoin)

Drug is CONTRAINDICATIONED at a specific level of kidney impairment because accumulation is unsafe. (Ex. Bleeding risk with anticoagulants)

Drug can cause further kidney damage ( ex. NSAIDS)

Drug can cause more harmful effects than usual when kidney function is reduced (ex. Hyperkalemia with aldosterone antagonist)

39
Q

What is CKD Mineral and Bone Disorder (CKD-MBD)?

A

Common in renal impairment pt and almost in all pt receiving dialysis.

Associated with fractures, cardiovascular disease and increase mortality.

40
Q

In relation to CKD-MBD patient with advanced kidney disease require monitoring for

A

Parathyroid Hormone (PTH)

Phosphorus (PO4)

Calcium (Ca)

Vitamin D levels

41
Q

Explain the interaction of Ca, PO4, Vitamin D and EPO in CKD

A

PO4 increase bc kidneys cannot eliminate

Vitamin D cannot be activated by kidney causing Calcium absorption to decrease

High PO4 and low Ca cause increase release of PTH (usually increase Ca reabsorption via feedback)

PTH pull Ca from bone causing demineralization and increase fracture

High PO4 levels( hyperphosphatemia) continued to stimulate PTH (secondary hyperparathyroidism) and hypercalcemia persist causing calcification and cardiovascular disease

Kidney produce less erythropoietin (EPO) resulting in decrease RBC production in the bone marrow which causes anemia.

42
Q

Hyperphosphatemia must be treated to prevent bone disease and fractures. Treatment is focused on;

A

Restricting dietary phosphate

Avoid dairy products, cola,chocolate and nuts

43
Q

72
Q

What is hemoglobin level is consider Anemia?

A

Hemoglobin less than 13 g/dL

73
Q

Why is Anemia common in CKD?

A

One of the causes of Anemia is LACK OF ERYTHROPOIETIN(EPO), which is normally PRODUCED by the KIDNEY.

EPO goes to the bone marrow to Stimulate the production of red blood cells (RBCs).

RBCs (contains hemoglobin) and they transport oxygen to the blood.

74
Q

Anemia in CKD is treated with what?

A
  • Erythropoiesis Stimulating Agents (ESAs)

- Iron

75
Q

Erythropoiesis Stimulating Agents (ESAs)

A

INDICATION: Anemia in CKD to prevent the need of blood transfusion.

EFFECTIVE: If adequate IRON is Available. Check ferritin and Tstat.

WHEN TO USE: hemoglobin less than 10 g/dL

WHEN TO D/C: Hemoglobin greater than 11 g/dL due to risk of thromboembolic disease (DVT, PE, MI, STROKE)

Risk: Elevated Blood Pressure and Thrombosis

TYPES:
E-poetin Alfa (PROCRIT, EPOGEN, RETACRIT)

Darbe-poetin Alfa (ARANESP) : long lasting formulation

76
Q

Why is iron levels low in ESRD and what is the solution?

A

Low level can be due reduce GI absorption and blood loss from dialysis treatment.

Solution: IV IRON is given at dialysis center.

77
Q

What is Hyperkalemia?

A

Normal Potassium: 3.5 to 5

Potassium Levels greater than 5.3 or 5.5

Clinical Concerns: levels greater than 5

Most Common Cause: DECREASED RENAL EXCRETION due to KIDNEY FAILURE.

SYMPTOMS:

Muscle Weakness

Bradycardia (monitor with ECG)

Fatal Arrhythmias ( (monitor with ECG))

78
Q

What is potassium?

A

Most abundant INTRACELLULAR CATION essential for life.

Normal daily intake: 1mEq/kg/day

Food: meats, beans and fruits

79
Q

How is potassium Eliminated?

A

via KIDNEY and partially by GUT

Renal potassium excretion is increased by:

Aldosterone hormone

Diuretics ( loops is greater than thiazides)

High urine flow ( osmotic diuresis)

Negatively charge ion in the distal tubule (bicarbonate)

80
Q

Potassium in normal kidney function?

A

High level potassium DOESNOT cause HYPERKALEMIA in normal kidney.

High level are offset by release of INSULIN,
which causes potassium to shift into the cells.

80
Q

Why are Diabetic patients at high risk of hyperkalemia?

A

Insulin deficiency reduce the ability to shift potassium into the cell.

Many patients with diabetes take ACE inhibitors or ARBs.

81
Q

Key Drugs that Raise Potassium Levels?

A

ACE Inhibitors

ARBs

Aldosterone Receptor Antagonists

Aliskiren

Canagliflozin

Drospirenone containing COCs

Sulfamethoxazole/ Trimethoprim

Transplant Drugs (Cyclosporine, Everolimus, Tacrolimus)

Other Drugs:

Glycopyrrolate

Heparin

NSAIDs

Potassium containing IV fluids (parenteral nutrition)

Potassium Supplements

Pentamidine

82
Q

Treatment of Severe Hyperkalemia?

A

D/C potassium source

Stabilize the Heart: Stabilize myocardial cells ( prevent arrhythmias)

Move it: rapidly shift potassium intracellularly

Remove it: induce elimination from the body.

84
Q
