Thyroid autoimmunity in patients with hidradenitis suppurativa: a case-control study

Area of Science:

• Immunology
• Dermatology
• Endocrinology

Background:

• Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition with unclear origins.
• Emerging evidence suggests HS may be immune-mediated.
• Autoimmune thyroid disease (AITD) is a well-established autoimmune disorder, previously linked to various skin conditions.

Purpose of the Study:

• To investigate the prevalence of thyroid autoimmunity in patients with hidradenitis suppurativa (HS).
• To compare thyroid autoimmunity markers between HS patients and age- and sex-matched controls.
• To explore potential links between HS pathogenesis and autoimmune mechanisms.

Main Methods:

• Analyzed thyroid autoantibodies and thyroid function tests in 70 HS patients.
• Included 70 age- and sex-matched healthy controls for comparison.
• Utilized statistical analysis to compare prevalence and parameter levels between groups.

Main Results:

• No statistically significant difference was observed in the prevalence of thyroid antibodies between HS patients and controls.
• Thyroid function parameters showed no significant variations between the HS group and the control group.
• The study did not find an association between HS and thyroid autoimmunity.

Conclusions:

• The findings suggest that conventional autoimmune mechanisms, specifically those related to thyroid autoimmunity, may not play a significant role in the pathogenesis of hidradenitis suppurativa.
• Further research is needed to elucidate the precise aetiopathogenesis of HS.
• This study provides novel insights into the relationship (or lack thereof) between HS and AITD.
