HYPERLIPIDEMIA AND XANTHOMATOSIS IN YELLOW-FOOTED ROCK WALLABIES () UNDER MANAGED CARE.

J Zoo Wildl Med 2022 Jun;53(2):470-479

Department of Medicine and Epidemiology and Karen C. Drayer Wildlife Health Center, University of California Davis School of Veterinary Medicine, Davis, CA 95616, USA.

Xanthomas are localized lipid deposits in organs with associated granulomatous inflammation. Xanthomatosis is a rare condition in both human and veterinary medicine and is often linked to inherited or acquired dyslipidemias. Three female yellow-footed rock wallabies () at a single institution were diagnosed via biopsy with cutaneous xanthomas secondary to hypertriglyceridemia and hypercholesterolemia, and an additional two female yellow-footed rock wallabies were diagnosed with xanthomas at a second institution.

Liver transplantation in an infant with cerebrotendinous xanthomatosis, cholestasis, and rapid evolution of liver failure.

Pediatr Transplant 2022 May 28:e14318. Epub 2022 May 28.

Institut für Pathologie, Medizinische Universität Graz, Österreich, Austria.

Background: Cerebrotendinous xanthomatosis (CTX) is a disorder of bile acid (BA) metabolism due to biallelic mutations in CYP27A1. The deposition of cholesterol and cholestanol in multiple tissues results, manifesting as neurologic disease in adults or older children. Neonatal cholestasis (NC) as a presentation of CTX is rare; it may self-resolve or persist, evolving to require liver transplantation (LT). Read More

Topical Simvastatin Improves Lesions of Diffuse Normolipemic Plane Xanthoma by Inhibiting Foam Cell Pyroptosis.

Front Immunol 2022 10;13:865704. Epub 2022 May 10.

Department of Dermatology, Xinhua Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.

Xanthoma pathogenesis is speculated to be associated with oxidized low-density lipoprotein (ox-LDL) deposition, although this remains unclear. Most patients with diffuse plane xanthomas present elevated blood lipid levels, and they benefit from treatment with oral lipid-lowering agents. However, there is no available treatment for diffuse normolipemic plane xanthoma (DNPX). Read More

Differing clinical features between Japanese siblings with cerebrotendinous xanthomatosis with a novel compound heterozygous CYP27A1 mutation: a case report.

BMC Neurol 2022 May 25;22(1):193. Epub 2022 May 25.

Department of Internal Medicine III, Division of Neurology and Clinical Neuroscience, Yamagata University Faculty of Medicine, 2-2-2 Iida-nishi, Yamagata, 990-9585, Japan.

Background: Cerebrotendinous xanthomatosis (CTX) is an autosomal-recessive lipid storage disorder caused by mutations in the CYP27A1 gene encoding the key enzyme in the bile acid synthesis, sterol 27-hydroxylase. Here, we report two Japanese CTX siblings with a novel compound heterozygous CYP27A1 mutation, showing different clinical phenotypes and responses to chenodeoxycholic acid (CDCA) therapy.

Case Presentation: The proband, a 32-year-old man, who had chronic diarrhea, bilateral cataracts, and xanthomas, demonstrated progressive neurological manifestations including ataxia, and spastic paraplegia during a 5-year follow-up period despite normalization of serum cholestanol after initiation of CDCA treatment.

Am J Ophthalmol 2022 May 17. Epub 2022 May 17.

Department of Pathology, Wills Eye Hospital, Sidney Kimmel Medical College at Thomas Jefferson University, Philadelphia, PA, USA; Department of Ophthalmology, Wills Eye Hospital, Sidney Kimmel Medical College at Thomas Jefferson University, Philadelphia, PA, USA.

Purpose: Frequent activating mutations in the mitogen-activated protein kinase (MAPK) pathway genes have been identified in histiocytoses. MAPK signaling consistently upregulates Cyclin D1. The goal of this study was to determine whether Cyclin D1 expression by immunohistochemistry is a useful diagnostic marker for periocular histiocytoses and to further characterize their genetic basis.

Lack of ApoA-I in ApoEKO Mice Causes Skin Xanthomas, Worsening of Inflammation, and Increased Coronary Atherosclerosis in the Absence of Hyperlipidemia.

Arterioscler Thromb Vasc Biol 2022 Jul 19;42(7):839-856. Epub 2022 May 19.

Department of Pharmacological and Biomolecular Sciences (M.B., S.M., A.C., E.F., F.B., R.O., A.L., G.D.N., G.C.), Università degli Studi di Milano, Italy.

Background: HDL (high-density lipoprotein) and its major protein component, apoA-I (apolipoprotein A-I), play a unique role in cholesterol homeostasis and immunity. ApoA-I deficiency in hyperlipidemic, atheroprone mice was shown to drive cholesterol accumulation and inflammatory cell activation/proliferation. The present study was aimed at investigating the impact of apoA-I deficiency on lipid deposition and local/systemic inflammation in normolipidemic conditions. Read More

Clinical and Genetic Analysis of a Family With Sitosterolemia Caused by a Novel ATP-Binding Cassette Subfamily G Member 5 Compound Heterozygous Mutation.

Front Cardiovasc Med 2022 26;9:887618. Epub 2022 Apr 26.

Fujian Provincial Hospital, Shengli Clinical Medical College of Fujian Medical University, Fuzhou, China.

Sitosterolemia (OMIM ##210250), also known as phytosterolemia, is a rare autosomal recessive disorder caused by mutations in the ATP-binding cassette subfamily G member 5 () or member 8 () genes. This leads to abnormal functions of the transporter sterolin-1 protein encoded by G5 and sterolin-2 protein encoded by G8, respectively, which can hinder the formation of stable / heterodimers, decreasing its ability to transport sterols. As a result, phytosterols in tissue or plasma are significantly increased, leading to early onset atherosclerosis-related diseases and xanthelasma of tendons and skin. Read More

Laboratory of Genetics and Molecular Cardiology (LIM13) (M.T.T., I.R.L., T.G.M.O., C.E.J., J.E.K., A.C.P.), University of São Paulo Medical School Hospital.

Background: Sitosterolemia is a rare autosomal recessive disorder caused by homozygous or compound heterozygous variants in . The disease is characterized by increased plasma plant sterols. Small case series suggest that patients with sitosterolemia have wide phenotypic heterogeneity with great variability on either plasma cholesterol levels or development of atherosclerotic cardiovascular disease.

A case of cerebrotendinous xanthomatosis with brain and spinal involvement without tendon xanthomas: Identification of a novel mutation of the CYP27A1 gene.

J Clin Lipidol 2022 May-Jun;16(3):281-285. Epub 2022 Apr 3.

Department of Neurology, 417 Army Share Fund Hospital, 10-12 Monis Petraki Str., PO 11521, Athens, Greece.

Cerebrotendinous xanthomatosis (CTX) is a rare inherited disorder of the alternative pathway of bile acid biosynthesis, due to mutation(s) of the gene CYP27A1, leading to sterol 27-hydroxylase deficiency. The latter results in a systematic deposition of cholestanol and cholesterol to the central nervous system and tendons, premature cataract, as well as the manifestation of systematic symptoms, such as chronic diarrhea, osteoporosis, and premature atherosclerosis. Due to its marked clinical heterogeneity, prompt diagnosis of this disorder is challenging. Read More

J Investig Med High Impact Case Rep 2022 Jan-Dec;10:23247096221089488

The University of Alabama at Birmingham, USA.

Primary biliary cholangitis (PBC) is a rare autoimmune disease characterized by intralobular bile duct destruction. Patients typically present with generalized symptoms including fatigue and pruritis, and less commonly, manifestations of lipid deposition including xanthomas and xanthelasmas. We report a case of a 31-year-old female with PBC-associated cirrhosis who had cutaneous xanthelasmas and diffuse gastric xanthomas secondary to hyperlipidemia and lipoprotein X that completely resolved following liver transplantation.
