Friends with kidney disease, especially those with kidney failure, have a lot of small rashes on their skin, and they are particularly itchy. During the day and night. Some people are obviously at night, and only when the patient scratches their skin they can feel slightly comfortable. Most of the cases are thought to be urticaria, which is probably caused by renal failure.
Because quite a few of them have no obvious symptoms, they are very easy to ignore, and some kidney diseases progress slowly. This makes kidney disease patients to tolerate gradually, and many patients do not notice it until the end stage of renal failure. Wait until there are many complications of kidney disease, then to the hospital to begin treatment.
When kidney patients appear skin pruritus, beware "hyperphosphatemia".
Today, it's mainly about the problems of hyperphosphatemia.
What is hyperphosphatemia?
The normal serum phosphorus concentration is 2.5-4.5 mg / dL (0.81 to 1.45 mmol / L), which is hyperphosphatemia when the blood phosphorus level is more than 4.5 mg/dL(1.45 mmol / L). Hyperphosphatemia is a common complication of chronic kidney disease. Mild hyperphosphatemia patients usually have no obvious symptoms, while joint pain, osteoporosis and vascular calcification can occur in severe cases, affect bone development and deformities in children.
Why does nephropathy appear hyperphosphatemia?
Kidney disease is the most common cause of hyperphosphatemia, and other causes are diabetes, hypothyroidism and hypocalcemia. Specifically:
1. Decrease of phosphorus excretion, such as renal failure and hypoparathyroidism;
2. Excessive phosphorus intake;
3. Phosphorus transfer into blood, such as acid-base imbalance, muscle necrosis, rhabdomyolysis and tumor lysis syndrome;
4. Drugs, take phosphorus-containing laxatives, oral phosphorus supplements and bisphosphonates.
How should the skin pruritus caused by hyperphosphatemia be treated?
Skin pruritus caused by hyperphosphatemia must be treated by hyperphosphatemia itself, can alleviate the symptoms of skin pruritus.
The treatment of hyperphosphatemia includes diet therapy and drug therapy. It is also necessary to actively treat basic diseases, such as treatment of renal failure, caused by renal failure; diet control, weight loss and hypoglycemic drugs, etc., caused by diabetes; supplements shall be given to those caused by hypothyroidism.
1. Reducing phosphorus intake and absorption
Phosphorus is mainly found in protein-rich foods, but it cannot be excessively restricted, otherwise it will affect the nutritional status of patients. Therefore, on the basis of ensuring nutrition, try to eat foods with a low "phosphorus / protein" ratio. Choose natural vegetable and animal proteins and avoid foods that contain a lot of additives, such as processed meat, sausages, ham, baking and canned fish, colas and other carbonated beverages.
2. Promoting phosphorus excretion
Patients with renal insufficiency, especially end-stage nephropathy, often need phosphate binders to increase phosphorus excretion from the intestine. Phosphorus binders can be pided into calcium containing phosphate binders and calcium free phosphate binders.
3. Increased dialysis clearance
Choose hemodialysis or peritoneal dialysis to remove phosphorus.
