Understanding Acne Vulgaris Through Research

Outline: Acne Vulgaris – New Insights From The Bench To The Clinic + overstimation of the risks of oral isotretinoin

  • Recent advances in acne research have allowed a better understanding of the pathogenesis and etiological factors associated with acne:
  • sebum overproduction by sebaceous glands is influenced by:
  1. dihydrotestosterone (DHT)
  2. Insulin-like Growth Factor (IGF)-1
  3. PPAR ligands
  4. neuromediators.
  5. Propionibacterium acnes has also has a role in addition to cause inflammation of activating toll-like receptors.
  • On the genetic front
  1. genetic polymorphisms in the interleukin-1alpha and IGF-1
  2. Common J. et al.found that filaggrin null* mutations (found in Ichthyosis Vulgaris and predisposing to Atopic Dermatitis) do not protect against acne vulgaris. (
  • With regards to treatment with oral isotretinoin a recent retrospective review (at the National Skin Centre enrolling over 2000 patients showed that not only it was effective, but that the incidence of side effects was very low.
