Angiopoietin-like protein 3 (ANGPTL3), which is part of a family of secreted glycoproteins that are structurally similar to angiopoietins, is principally expressed in the liver and is involved in lipid metabolism and angiogenesis. The aim of this study was to determine the clinical significance of serum ANGPTL3 levels, measured with a specific enzyme-linked immunosorbent assay, in patients with systemic sclerosis. Serum ANGPTL3 levels correlated positively with skin score in diffuse cutaneous systemic sclerosis with a disease duration ≤6 years. Furthermore, the prevalence of digital ulcers was significantly higher in patients with elevated serum ANGPTL3 levels than in other patients. Moreover, among patients excluding diffuse cutaneous systemic sclerosis with disease duration ≤6 years, serum ANGPTL3 levels correlated positively with estimated right ventricular systolic pressure. In conclusion, ANGPTL3 may contribute to the development of progressive skin sclerosis and proliferative obliterative vasculopathy, such as digital ulcers and pulmonary vascular involvement leading to pulmonary arterial hypertension, in systemic sclerosis.

More about this publication?
  • Acta Dermato-Venereologica is a bi-monthly international peer-reviewed journal for clinical and experimental research in the field of dermatology and venereology.

    It was founded in 1920 by Johan Almqvist and edited during 1936-1969 by Sven Hellerström. Since 1970, the journal has been published for the Society for the Publication of Acta Dermato-Venereologica on a non-profit basis.

    Acta Dermato-Venereologica publishes high-quality manuscripts in English dealing with new observations on basic dermatological and venereological research, as well as clinical investigations. Each volume also features a number of review articles in special areas, as well as short Letters to the Editor to stimulate debate and to disseminate important clinical observations. Acta Dermato-Venereologica has rapid publication times and is amply illustrated with a large number of colour photographs to enhance understanding.

    Acta Dermato-Venereologica covers inter alia:

    • ~ Atopic dermatitis and contact allergy
    • ~ Facial dermatoses and adnexal disorders
    • ~ New treatments
    • ~ Psoriasis and genodermatoses
    • ~ Psychodermatology
    • ~ Sexually transmitted diseases
    • ~ Skin biology and inflammation
    • ~ Skin cancer and pigmentation
    • ~ Skin immunology and lymphoma
    • ~ Urticaria and itch

    Extensive papers, proceedings from congresses and symposia are printed as supplements to the journal. Announcements concerning pertinent dermatological meetings and books received are also published.
    Readership: Doctors and scientists interested in dermatology, skin biology and venereology.

    Acta Dermato-Venereologica has an impact factor of 3.007.
