title: [Effect of LDL-apheresis on a case of Cerebrotendinous Xanthomatosis].
abstract: Cerebrotendinous Xanthomatosis (CTX) is a rare familial disease characterized by tendon-xanthomas, cataracts, progressive cerebellar ataxia, dementia and an elevation of serum cholestanol with normal levels of cholesterol. Although the pathogenesis of CTX is not fully understood, increment of cholestanol is suggested one of the major metabolic derangements of the disease. Recently, the LDL-apheresis has been developed as a new therapeutical equipment in the field of hyperlipidemia and been widely used to reduce the levels of LDL-cholesterol by selective LDL adsorption. From the point of view that cholestanol is involved mainly in LDL-cholesterol (1.019 less than d less than 1.063), we used this LDL-apheresis in the aim of reducing the cholestanol in 58 years old woman with typical sign and symptoms of CTX. The levels of serum cholestanol and cholesterol before the treatment with LDL-apheresis, were 10.7 micrograms/ml and 175 mg/dl respectively. Also the ratio of cholestanol/cholesterol indicated 0.63. By the first procedure of apheresis, the level of cholestanol was markedly decreased to 5.2 micrograms/ml (50%). Several LDL-apheresis treatments were carried out once a month. During 5 months treatments, neurological deterioration was arrested, dementia which included disorientation and recent-memory loss, cleaned a little. Although the xanthomas did not decrease in size, this patients was better oriented to person, place, time and was able to speak rationally, 2nd her cerebellar dysfunction revealed improvement. From our new experiments-we believe that the LDL-apheresis offers the strong hope of preventing the progress on cerebrotendinous xanthomatosis.
