Question

What is the treatment for hyperphosphatemia in chronic renal failure?

1) Phosphate binders
2) Calcium supplements
3) Vitamin D analogues
4) All of the above

Answer 1

The treatment for hyperphosphatemia in chronic renal failure includes phosphate binders, calcium supplements, and vitamin D analogues. All these components may be part of the treatment regimen to manage the elevated phosphate levels and associated metabolic disturbances.

Step-by-step explanation:

The treatment for hyperphosphatemia in chronic renal failure involves interventions to reduce phosphate levels in the blood. This condition is often due to reduced excretion of phosphate, which is associated with hypocalcemia, often stemming from a deficiency in vitamin D3. The main treatment strategies include:

• Phosphate binders: These are medications that bind phosphate in the gastrointestinal tract, preventing its absorption and reducing serum phosphate levels.
• Calcium supplements: These may be used to correct associated hypocalcemia, but caution is advised as they can contribute to vascular calcification if used excessively in the presence of high phosphate levels.
• Vitamin D analogues: These are used to help manage secondary hyperparathyroidism and to improve calcium and phosphate metabolism.

Therefore, the correct answer to the question is 4) All of the above, as managing hyperphosphatemia in chronic renal failure can involve a combination of these treatments depending on the individual patient's need.
