Sex-based clinical and immunological differences across lupus erythematosus subtypes: a cross-sectional multicentre study from China

Authors' conclusion

Across the subtypes, several clinical manifestations show a consistent sex distribution: ACLE lesions, arthritis, non-scarring alopecia, Raynaud's phenomenon and autoantibodies occur more frequently in women with LE, whereas the proportions of DLE and SCLE lesions are higher in men with LE. In addition, certain features exhibit subtype-specific sex differences: among patients with SCLE, DLE and CHLE, women show a greater propensity for systemic involvement, whereas in those with SLE and ACLE, men demonstrate a higher tendency toward systemic disease.
