title: [Results and prospects of therapy of type IV dyslipidemia with chenic acid].
abstract: Administration of 500 mg/day chenodeoxycholic acid for 60 days in a series of 44 patients with type IV dyslipidaemia led to gradual normalisation of triglycerides by the end of the treatment. Falls were greater in subjects with initially higher values, but were independent of age, sex, weight and type of diet. Further falls were obtained by repeating the treatment in some cases when prebetalipoproteins rose again. Decreases were already evident by the 5th day (about 24%) and could be obtained with only 4 mg/Kg/day. The rapid effect of the acid and its specific action on prebetalipoproteins were demonstrated by examination of lipid curves after a glyco-lipid load with and without pretreatment with chenic acid. Encouragement of the shunt of triacylglycerols towards the phosphoglycerides during hepatic synthesis of triglycerides is put forward as the most likely mechanism of action in endogenous hyper-triglyceridaemia. The chemical composition of bile is interfered with, which may explain why cholesterol lithiasis is significantly more common in type IV dyslipidaemia than in other forms and in controls, as shown by statistical analysis.
