Chronic diarrhea and juvenile cataracts: think cerebrotendinous xanthomatosis and treat.

Cerebrotendinous xanthomatosis is an autosomal recessive disease of bile acid synthesis caused by 27-hydroxylase deficiency. Treatment with chenodeoxycholic acid normalizes cholestanol concentrations and abrogates progression of the disease. We present 4 patients with cerebrotendinous xanthomatosis within 1 family who were treated with chenodeoxycholic acid for 14 years.

The neuropathology of cerebrotendinous xanthomatosis revisited: a case report and review of the literature.

Cerebrotendinous xanthomatosis (CTX), a rare autosomal-recessive lipid storage disease, has been well characterized clinically and biochemically, and recently also from the molecular biological aspect. However, only a very few publications deal with its neuropathology, and views on its pathogenesis vary. Based on a recently examined case, we propose that central-peripheral distal axonopathy is the major pathogenetic mechanism of nervous system injury in CTX.

Cerebrotendinous xanthomatosis in the Israeli Druze: molecular genetics and phenotypic characteristics.

Cerebrotendinous xanthomatosis (CTX) is an autosomal recessive lipid-storage disease caused by mutations in the sterol 27 hydroxylase gene (CYP27). Clinically, a multitude of neurological, skeletal, and vascular manifestations are usually present. Premature atherosclerosis has been reported in CTX and may be related to the metabolic derangement caused by the deficiency of the enzyme.

Magnetic resonance imaging in cerebrotendinous xanthomatosis: a prospective clinical and neuroradiological study.

We describe MRI findings in 13 persons with typical clinical, EEG, CT and biochemical features of cerebrotendinous xanthomatosis (CTX). MRI showed brain (13/13) and cerebellar (12/13) atrophy and diffuse white matter hypodensity (4/13) presumably reflecting sterol infiltration with demyelination. Focal lesions were rare (2/13).

Molecular genetics of cerebrotendinous xanthomatosis in Jews of north African origin.

Cerebrotendinous xanthomatosis (CTX) is an autosomal recessive sterol storage disease characterized by the accumulation of a bile alcohol, cholestanol, in diverse tissues. The disorder is manifested by extensive nervous system involvement, juvenile cataracts, tendon xanthomas, and premature atherosclerosis and is caused by sterol 27-hydroxylase (EC 1.14.

Frameshift and splice-junction mutations in the sterol 27-hydroxylase gene cause cerebrotendinous xanthomatosis in Jews or Moroccan origin.

The sterol 27-hydroxylase (EC 1.14.13.

Osteoporosis and increased bone fractures in cerebrotendinous xanthomatosis.

Significant osteoporosis determined by skeleton radiography and bone densitometry was found in 15 patients with cerebrotendinous xanthomatosis (CTX) whose mean age was 31 +/- 11 years. In three CTX patients, bone biopsies confirmed osteoporosis. Nine patients also sustained bone fractures following minimal trauma.

[Cerebrotendinous xanthomatosis].

Cerebrotendinous xanthomatosis (CTX) is a rare familial lipid storage disease caused by defective bile acid synthesis. As a result, cholestanol, a derivative of cholesterol, is accumulated by virtually every tissue, predominantly by the nervous system, xanthomas and bile. Clinically, progressive neurologic dysfunction, tendon xanthomas, cataracts, osteoporosis and atherosclerosis are commonly found.

Epileptic seizure as a presenting symptom of cerebrotendinous xanthomatosis.

Cerebrotendinous xanthomatosis (CTX) is a rare hereditary disease characterized by xanthomata of tendons, osteoporosis, cataracts, cerebellar ataxia, spastic paresis, and dementia. Though electroencephalographic (EEG) abnormalities are frequent in CTX, epileptic seizures have not been recognized as a major feature. A CTX patient is reported who presented with a generalized epileptic seizure and was evaluated with EEG and neuropsychological testing.

Mollaret's meningitis in association with delivery in a Bedouin woman; a case report.

A young Bedouin woman suffered two clusters of recurrent benign aseptic (Mollaret's) meningitis in association with two of her deliveries. This is the first case of Mollaret's syndrome related to delivery, and also the first presentation in a Bedouin.

Computed tomography of tendinous xanthomata in cerebrotendinous xanthomatosis.

Tendinous xanthomata with maximum expression on Achilles tendons are a characteristic feature of cerebrotendinous xanthomatosis, a rare autosomal recessive lipid storage disease. Twenty patients are under review; three of them, at different stages of the disease, underwent computed tomographic (CT) examination. CT demonstrates with a high degree of accuracy the increased size of the tendon and its heterogeneous structure resulting from cholesterol and cholestanol crystal deposits.

Biochemical abnormalities in cerebrotendinous xanthomatosis.

Cerebrotendinous xanthomatosis (CTX) is a rare recessive inherited lipid storage disease that was first described by Van Bogaert. Although the principal clinical presentation affects the nervous system with dementia, spinal cord paresis, cerebellar ataxia and peripheral neuropathy, the liver is is the organ where the major biochemical abnormalities are expressed. The following sections deal with the pathogenesis and treatment of the biochemical problems in CTX.

Wernicke's encephalopathy in acquired immune deficiency syndrome (AIDS): a case report.

A 40-year-old male, with established AIDS developed cachexia and dementia. At autopsy opportunistic infections were found. An additional neuropathological finding was Wernicke's encephalopathy.

Cerebrotendinous xanthomatosis.

Cerebrotendinous xanthomatosis is a rare familial lipid storage that is caused by a defect in bile acid synthesis. As a result, large amounts of cholestanol, the 5 alpha-dihydro derivative of cholesterol, accumulate in virtually every tissue, with extra large deposits in the nervous system, xanthomas, and bile. Clinically, progressive neurologic dysfunction, tendon xanthomas, cataracts, and atherosclerosis are commonly found.

Clustering of strokes in association with meteorologic factors in the Negev Desert of Israel: 1981-1983.

Clinical observations of the apparent clustering of daily stroke admissions to a regional hospital in an arid climate prompted our investigation of possible meteorologic factors associated with stroke admissions. Daily hospitalization and meteorologic data were studied for 895 patients with stroke admitted to Soroka Medical Center, Beer-Sheva, Israel, during 1981, 1982, and 1983. The average daily incidence of stroke was about twice as great on relatively warm days as on relatively cold ones.

Pregnancy in women with cerebrotendinous xanthomatosis (CTX): high risk condition for fetus and newborn infant?

Cerebrotendinous xanthomatosis (CTX), is one of the few autosomal recessive progressive storage diseases allowing affected individuals to reproduce. We investigated 38 CTX patients and most of their families. The possibility of a high risk situation for the fetus and/or the apparently healthy newborn infant born to CTX mothers and female carriers of the gene is discussed for genetic counseling purposes and in view of available treatment.
