Endoplasmic reticulum stress and muscle dysfunction in congenital lipodystrophies.

Biochim Biophys Acta Mol Basis Dis 2021 Jun 11;1867(6):166120. Epub 2021 Mar 11.

Departamento de Medicina Clínica, Hospital Universitário Onofre Lopes (HUOL)/UFRN, Natal, RN, Brazil.

Lipodystrophy syndromes are a group of rare diseases related to the pathological impairment of adipose tissue and metabolic comorbidities, including dyslipidemia, diabetes, insulin resistance, hypoleptinemia, and hypoadiponectinemia. They can be categorized as partial or generalized according to the degree of fat loss, and inherited or acquired disorders, if they are associated with genetic mutations or are related to autoimmunity, respectively. Some types of lipodystrophies have been associated with changes in both redox and endoplasmic reticulum (ER) homeostasis as well as muscle dysfunction (MD). Read More

Imaging spectrum of abnormal subcutaneous and visceral fat distribution.

Insights Imaging 2020 Feb 13;11(1):24. Epub 2020 Feb 13.

Department of Radiology, Teikyo University School of Medicine, 2-11-1 Kaga Itabashi-ku, Tokyo, 173-8606, Japan.

Adipose tissue plays multiple and complex roles not only in mechanical cushioning and energy storage but also as an important secretory organ that regulates energy balance and homeostasis multilaterally. Fat tissue is categorized into subcutaneous fat tissue (SCAT) or visceral fat tissue (VSA) depending on its distribution, with the two having different metabolic functions. Near-total lack of fat in congenital/acquired generalized lipodystrophy, cachexia, or any other severe malnutrition condition induces severe multi-organ dysfunction due to lack of production of leptin and other adipokines.

Fatty liver in lipodystrophy: A review with a focus on therapeutic perspectives of adiponectin and/or leptin replacement.

Metabolism 2019 07 6;96:66-82. Epub 2019 May 6.

Department of Internal Medicine, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA, USA; Section of Endocrinology, Boston VA Healthcare System, Harvard Medical School, Boston, MA, USA.

Lipodystrophy is a group of clinically heterogeneous, inherited or acquired, disorders characterized by complete or partial absence of subcutaneous adipose tissue that may occur simultaneously with the pathological, ectopic, accumulation of fat in other regions of the body, including the liver. Fatty liver adds significantly to hepatic and extra-hepatic morbidity in patients with lipodystrophy. Lipodystrophy is strongly associated with severe insulin resistance and related comorbidities, such as hyperglycemia, hyperlipidemia and nonalcoholic fatty liver disease (NAFLD), but other hepatic diseases may co-exist in some types of lipodystrophy, including autoimmune hepatitis in acquired lipodystrophies, or viral hepatitis in human immunodeficiency virus (HIV)-associated lipodystrophy.

Analysis of C3 Nephritic Factors by ELISA.

Lillemor Skattum

Methods Mol Biol 2019 ;1901:177-182

Department of Laboratory Medicine, Section of Microbiology, Immunology and Glycobiology, Lund University, Lund, Sweden.

Autoantibodies to the C3 convertase of the alternative pathway of complement, called C3 nephritic factors (C3NeF), cause persistently low C3 in the circulation and production of C3 degradation fragments due to prolonged stabilization of the C3 convertase. C3NeF are associated with glomerulopathy, acquired partial lipodystrophy, and less frequently with increased susceptibility to meningococcal infection. Analysis of C3NeF is an important part of the diagnostic workup of C3 glomerulopathy, but their identification is difficult presumably due to considerable heterogeneity. Read More
