Women with clinically diagnosed lipedema show a higher prevalence of the celiac-associated HLA-DQ2/DQ8 haplotypes than the general population (any HLA 61.1% vs 53.7%; both haplotypes 7.4% vs 1.2%).

Evidence over time

• Assessing the Prevalence of HLA-DQ2 and HLA-DQ8 in Lipedema Patients and the Potential Benefits of a Gluten-Free Diet — Amato et al. (2023) ✓ verified — consistent · cross sectional · n=95 · 2023 · risk of bias: high · reading confidence: high
  “Comparação com população geral brasileira mostrou diferenças estatisticamente significativas (χ²=26,128; gl=3; p<0,0001): HLA-DQ2 47,37% vs 41,20%, HLA-DQ8 22,11% vs 11,30%, qualquer HLA 61,05% vs 53,70%, ambos HLAs 7,37% vs 1,2% — coeficiente de contingência muito próximo de zero indicando tamanho ”

• THE PREVALENCE OF HLA DQ2 AND DQ8 IN PATIENTS WITH CELIAC DISEASE, IN FAMILY AND IN GENERAL POPULATION — CECILIO & BONATTO (2015) ✓ verified — contextual · cross sectional · n=80 · 2015 · risk of bias: moderate · reading confidence: high

Context (PECO)

Answers these questions

• Is lipedema linked to gluten sensitivity, celiac disease, or HLA-DQ2/DQ8? consistent

Gaps & caveats

No concurrent control; selection bias toward symptomatic patients; cannot establish causation.
