Treating the underlying kidney disease is a major goal of therapy in patients that have been diagnosed with secondary hyperparathyroidism. Abnormally high levels of phosphorous in the blood is treated by using chemicals that bind to the excess phosphorous in the blood, and the diet is controlled to limit phosphorous ingestion by way of food.
To overcome calcitriol deficiency, calcitriol is given to increase calcium levels, but in very small doses that are calculated by your veterinarian based on your cat's specific need.
Depending on the severity of kidney failure, it is very important to check the serum concentrations of calcium, phosphorous and urea nitrogen weekly or monthly. If your cat is receiving calcitriol, you will need to closely monitor the cat's condition, as calcitriol therapy may lead to some untoward symptoms or complications.
Your cat's parathyroid hormone (PTH) concentrations will also need to be checked on a regular basis. Though renal secondary hyperparathyroidism treatment may slow down the overall progression of kidney failure, the long-term prognosis is frequently very poor in these patients.
