Summary

A family history of acne (A+) is linked to earlier onset and more severe acne, often requiring oral treatments and leading to relapses. Heredity influences acne progression and treatment outcomes.

Area of Science:

  • Dermatology
  • Epidemiology
  • Genetics

Background:

  • The influence of genetic predisposition on acne vulgaris severity and treatment outcomes requires further elucidation.
  • Understanding hereditary factors is crucial for predicting acne prognosis and tailoring therapeutic strategies.

Purpose of the Study:

  • To investigate the clinical and evolutive characteristics of acne in patients with a positive family history (A+) compared to those without (A-).
  • To evaluate treatment responses and identify potential differences based on the presence and origin of a family history of acne.

Main Methods:

  • A prospective epidemiological study involving 151 acne patients, categorized as A+ or A-.
  • Comparison of clinical and therapeutic parameters between groups.
  • Subgroup analysis of A+ patients based on paternal (F+) or maternal (M+) family history.

Main Results:

  • Clinical presentation of acne was comparable between A+ and A- groups.
  • Acne onset occurred earlier, often pre-pubertally, in the A+ population.
  • A+ patients exhibited increased use of oral treatments, higher relapse rates post-isotretinoin, and a greater burden of retentional lesions, particularly in M+ and M+F+ subgroups.

Conclusions:

  • Heredity significantly impacts acne development and progression, serving as a critical prognostic factor.
  • A family history of acne is associated with earlier disease onset, increased retentional lesions, and challenges in treatment management.
