Xanthomatoses

Therefore, the case that is presented in this report is unique. An 18-year-old woman was admitted to our department because she presented with morning stiffness, joint deformation, and swelling in both hands. [ncbi.nlm.nih.gov]

Cataracts are present in 76% cases and are generally seen as early as 5-6 years of age. [1] Seizures are encountered in 40-50% cases, and can be the presenting problem in some cases. A sensory-motor neuropathy has also been documented. [neurologyindia.com]

Infants may present with cholestasis and liver dysfunction. Xanthomata may appear in the 2nd or 3rd decade of life, in the Achilles and other tendons (elbow, hand, patella, neck). [orpha.net]

  • Soft Tissue Swelling

    Computed tomography of the right hand showed soft tissue swelling on multiple small joints, including metacarpophalangeal and proximal interphalangeal joints, but without obvious bone destruction. [ncbi.nlm.nih.gov]

    A single soft tissue swelling was present on the Achilles tendon. CT scan showed hypodensity in bilateral cerebellar white matter and brainstem. [neurologyindia.com]

    (a and b) multiple firm to hard, mobile from side to side, non tender swellings of size varying from 6 4 cm to 3 3 cm present over posterior aspect of both ankles, attached to tendoachilles; (c) plain lateral radiographs of both ankles shows soft tissue [idoj.in]

    The cholesterol-to-cholestanol ratio is said to be a better indicator of disease than the cholestanol concentration alone. [24] The radiographs revealed fusiform soft tissue swellings, which were found as hyperintense signals in those regions in the MRI [jdrntruhs.org]

  • Pseudotumor

    Mostly known as pseudotumors, xanthomas consist of connective tissue containing mainly cholesterol, triglycerides, and numerous foamy macrophages. [ncbi.nlm.nih.gov]

  • Wheelchair Bound

    There was progressive worsening of motor function, so that she became wheelchair-bound at the age of 30 and bedridden at 49. She has had no effective interaction for the past 3 years and she is under exclusive gastrostomy feeding. [mdsabstracts.org]

  • Aspiration

    We report a rare case of tendinous xanthomatosis in a 23-year-old female, diagnosed on aspiration cytology. [ncbi.nlm.nih.gov]

    Lens opacification may require extraction at that time and aspirated lens material may contain lipid-containing vacuoles. [disorders.eyes.arizona.edu]

  • Joint Deformity

    An 18-year-old woman was admitted to our department because she presented with morning stiffness, joint deformation, and swelling in both hands. [ncbi.nlm.nih.gov]

    Xanthomas can cause motor restriction and joint deformities, resulting in ambulation disabilities. [jdrntruhs.org]

    Xanthomas can cause motor restriction and joint deformities, resulting in various orthopedic sequelae. [emedicine.medscape.com]

  • Morning Stiffness

    An 18-year-old woman was admitted to our department because she presented with morning stiffness, joint deformation, and swelling in both hands. [ncbi.nlm.nih.gov]

  • Osteopenia

    Osteopenia is evident by total body densitometry in untreated individuals. Individuals may have marked thoracic kyphosis. [leukodystrophyresourceresearch.org]

  • Xanthoma

    Xanthomas are described as deposits in the skin and subcutaneous tissues. Mostly known as pseudotumors, xanthomas consist of connective tissue containing mainly cholesterol, triglycerides, and numerous foamy macrophages. [ncbi.nlm.nih.gov]

    Wikipedia: Xanthoma xanthomas xanthomata xanthomatosis a deposition of yellowish cholesterol-rich material in tendons or other body parts in various disease states. [memidex.com]

    Tendon xanthomas may cause discomfort and interfere with tendon flexibility. While many affected people develop tendon xanthomas, these nodules may not be easily visible underneath the skin. [ghr.nlm.nih.gov]

  • Spinal Cord Syndrome

    None of them had cerebellar signs, dementia or peripheral neuropathy at the moment of presentation of the spinal cord syndrome and, except for patient B2, none of them had tendon xanthomas (Table 1 ). [brain.oxfordjournals.org]

  • Onset in Adolescence

    Cerebrotendinous xanthomatosis (CTX) is a lipid storage disease characterized by infantile-onset diarrhea, childhood-onset cataracts, adolescent-to-young-adult-onset tendon exanthemas, and adult-onset progressive neurologic dysfunction (dementia, psychiatric [leukodystrophyresourceresearch.org]

Results : Laboratory workup revealed cholestanol of 19.6 mmol/L (Reference: 2-12 mmol/L) increased cholestanol/cholesterol rate of 4.55 ( Reference : 0.16 /- 0.05 ) and increased cerebrospinal fluid albumin of 24.4 mg dL (Reference: up to 3.5). [mdsabstracts.org]

MRI studies of the brain are an important component of the diagnostic workup for CTX. It may show bilateral hyperintensity of the dentate nuclei and cerebral and cerebellar white matter. [eyewiki.aao.org]

  • Hypercholesterolemia

    Two unrelated individuals were referred to Lipid Clinics in The Netherlands and Chile with extreme xanthomatosis and hypercholesterolemia. [ncbi.nlm.nih.gov]

Management and treatment First-line treatment is based on chenodeoxycholic acid (CDCA) replacement therapy, which normalizes BAS and cholestanol concentrations, and improves neurological symptoms. [orpha.net]

Prognosis Early diagnosis and treatment are crucial to prevent progressive accumulation of cholestanol and cholesterol: disease progression may be halted and in some cases reversed. Treated patients may have a normal lifespan. [orpha.net]

Treatment Early diagnosis and long-term treatment with a medication called chenodeoxycholic acid improves neurological symptoms and contributes to a better prognosis. [geneticdisordersuk.org]

Behavioral/personality disturbance in childhood or adolescence, especially when accompanied by learning difficulties, should therefore lead to further investigation to exclude CTX, as early diagnosis and treatment is critical for prognosis. [nature.com]

Prognosis If cerebrotendinous xanthomatosis is untreated, life expectancy is into the fifth and sixth decades; however, confirmed deaths have been reported as early as age 4 months. This is a progressive and terminal disease if left untreated. [emedicine.medscape.com]

Etiology CTX is caused by mutations in the sterol 27-hydroxylase gene ( CYP27A1 ; 2q33-qter). Sterol 27-hydroxylase catalyzes the first step in the oxidation of the side-chain of sterol intermediates in the bile acid synthesis (BAS) pathway. [orpha.net]

ETIOLOGY – GENETICS CYP27A1 gene codes for the mitochondrial enzyme sterol 27-hydroxylase, which is involved in bile acid synthesis. The CYP27A1 gene is located on chromosome 2q33-qter and contains nine exons. [flipper.diff.org]

Eye care professionals are in a unique position to identify and diagnose CTX at a time when serious disability can be prevented. [eyewiki.aao.org]

If CTX is diagnosed before there has been too much deterioration of the brain, proper treatment can potentially prevent the brain damage that can lead to severe mental dysfunction and eventually death. [ulf.org]
