چکیده انگلیسی
Animal models are widely used in systemic sclerosis (SSc) research. We set out to determine whether ultrasonography (US) could be used to assess skin fibrosis in two complementary SSc-models: the bleomycin-induced dermal fibrosis model and the tight-skin 1 mouse model. Back skin thickness was measured using a high-frequency ultrasound dedicated to the small animal. There was no significant difference in dermal thickness measured by US between mice injected with bleomycin and those treated with NaCl. These results were inconsistent with histological analyses. Mean US hypodermal thickness was significantly higher in tight-skin 1 mice as compared with Pa/Pa control subgroup (p = 0.02). Histologic and US measures of dermal and hypodermal thicknesses in this model were well correlated (r = 0.79). The intra-observer concordance was 0.96 for hypodermal thickness. US is reliable and sensitive in detecting hypodermal thickening in the tight-skin 1 mouse model. Further larger studies are warranted to better determine the place of US in SSc-research.
