The effects of calcitonin on lipid metabolism were investigated in three kinds of rats, one strain of rabbits, and a primary culture of rat hepatocytes.
We wished to investigate the pathophysiology of hypertriglyceridemia in chronic renal failure. Our subjects were 30 patients under hemodialysis for at least five years who had never taken vitamin D analogues or calcitonin preparations. During those five years, triglycerides were high, with no significant changes, although the cholesterol level decreased significantly 10 to 1 2 months after the first hemodialysis treatment. There was a significant correlation between alkaline phosphatase and triglycerides (p < 0.025) in these patients in the same assay. In the two patients with hypertriglyceridemia, serum triglycerides decreased to within the normal range by six months after parathyroidectomy, and remained there 30 months after surgery. These results suggested that secondary hyperparathyroidism may be involved in the pathophysiological mechanism of hypertriglyceridemia seen in chronic renal failure.
There are many factors which are related to the pathogenesis of renal osteodystrophy. Among those, nutritional factors would also be very im portant. Calcium, phosphate, protein, fat and calorie intake may influence the pathogenesis of
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
