[Occupational semicircular lipoatrophy associated with serum adipokine abnormalities].

Objectives: The aim of this study was to examine the relationship between semicircular lipoatrophy (SL), inflammation marker (high sensibility C-reactive protein [hs-CRP]), adipokines (leptine, chemerine and vaspine) and autoimmune markers (rheumatoid factor [RF], C3 and C4 complement fractions, antinuclear antibodies [ANA], HLA DR3, and DR4). Chemerine is an adipokine, but also is an immunity marker.

Methods: A case-control study was performed in May 2013; 21 cases were included. The closest healthy coworker to each case was used as a control. We calculated Kruskal-Wallis nonparametric test.

Results: We found statistical significance (P<.05) between SL and raised hs-CRP, raised leptine and low chemerine.

Conclusions: i) There seems to be an underlying inflammatory component (raised hs-CRP) in SL; ii) adipokine alteration (raised leptine and low chemerine) supports the idea that adipocytic differentiation is affected in SL, and iii) we have not found any immune marker associated with SL, except chemerine itself, which could explain a possible association between SL and immunity.
