BackgroundAn association between granuloma annulare (GA) and dyslipidaemia has been reported. Adipophilin expression may play a plausible role as a cutaneous biomarker for dyslipidaemia in patients with GA; however, this potential link remains to be explored.MethodsPatients with GA were identified at our hospital between January 1, 1990, and December 31, 2021, with a thorough review of their clinical and histological characteristics. Adipophilin staining was assessed in biopsies of GA lesions.ResultsA total of 107 patients with GA were included. The prevalence of dyslipidaemia in patients with positive adipophilin staining was clearly higher than in those with negative labelling (62.3% vs 13.3%). Relative to the dyslipidaemia risk for patients with negative adipophilin expression, the odds for patients with positive adipophilin expression were increased 10-fold (OR: 10.8; p-value<.01). We identified 23 incident cases of dyslipidaemia over a median follow-up period of 91 months among 54 patients with no history of dyslipidaemia. The patients with positive adipophilin expression showed a higher risk of developing dyslipidaemia (HR: 8.9; p-value<.01).ConclusionsPatients with positive adipophilin staining in their GA biopsies were found to be associated with a higher risk for both baseline and incident dyslipidaemia.Copyright © 2024.
