BACKGROUND/ OBJECTIVE: We sought to evaluate if autologous hematopoietic stem cell transplantation (AHSCT) influences the functional status of systemic sclerosis (SSc) patients. METHODS: From 2014 to 2018, a cohort of 27 SSc patients was assessed before, and at 6 and 12 months after AHSCT for modified Rodnan's skin score (mRSS), mouth opening, hand grip strength, range of motion (ROM), functional ability of upper limbs (DASH questionnaire and Cochin hand function scale-CHFS), 6-minute walk test (6MWT), and quality of life (SF-36 questionnaire). Linear regression models with random effects and Spearman's test were used for statistical analysis. RESULTS: At 6 and 12 months after AHSCT, respectively, we observed significant improvement of mRSS (p < 0.01 and p < 0.01), mouth opening (p = 0.02 and p < 0.01), hand function (DASH, p < 0.01 and p < 0.01; CHFS, p < 0.01 and p < 0.01; strength, p < 0.01 and p < 0.01), physical capacity (6MWT, p = 0.02 and p = 0.03) and physical (p < 0.01 and p < 0.01) and mental (ns and p = 0.02) component scores of SF-36. At 12 months after AHSCT, ROM measurements improved (p < 0.05) in five out of six evaluated joints in both hands, compared to baseline. Correlation was significant between physical capacity and quality of life (R = 0.62; p < 0.01), between DASH and quality of life (R = -0.48; p = 0.03), and between skin involvement and wrist ROM measures (dominant hand, R = -0.65, p < 0.01; non-dominant hand, R = -0.59; p < 0.01). CONCLUSIONS: AHSCT enhances the functional status of SSc patients in the first year of follow-up, significantly improving hand function, physical capacity and quality of life. These results are interpreted as positive outcomes of AHSCT for SSc.
