Title: Systemic Sclerosis and Related Disorders – Clinical Poster III

Session Type: Poster Session D

Session Time: 1:00PM-3:00PM

Background/Purpose: Systemic sclerosis (SSc) is characterized by skin and organ involvement and chronic disease course. In particular, involvement of the gastrointestinal tract and systemic inflammation can have a negative impact on nutritional status. The aim of this study was to assess the differences in the nutritional status of SSc patients and healthy controls (HC) and the association with disease-specific features.

Methods: 100 patients with SSc (85 females; mean age 55.5; disease duration 4.0 years; lcSSc 59 / dcSSc 41) and 100 age-/sex-matched HC (85 females, mean age 55.3) without rheumatic diseases were included. Patients with SSc fulfilled the 2013 ACR/EULAR criteria. Levels of selected nutrition parameters were measured in sera drawn after 8 hours of fasting by routine analytic methods. In SSc patients, disease activity was evaluated by the ESSG composite index, skin involvement by the modified Rodnan skin score (mRSS), and organ involvement and current treatment were recorded.

Results: Differences in disease activity and skin involvement were observed between the two subtypes of SSc, whereas comorbidities, internal organ involvement, and treatment were statisticaly comparable. Serum levels of proteins (total protein, albumin, prealbumin, transferrin), minerals (Fe, Mg, Zn), and vitamins (calcidiol, calcitriol) were decreased (p=0.060 for total protein, p< 0.05 for the rest). On the other hand, orosomucoid (an inflammatory marker) and C-peptide were increased in SSc compared to HC (p< 0.05). Patients with dsSSc had a more unfavorable decrease in minerals (Fe, Mg) than lcSSc when compared to the corresponding age-/sex-matched HC. Among the individual SSc subsets, lcSSc had a trend to higher albumin, Mg, and Zn levels (p< 0.10) and significantly higher albumin levels (p=0.033) compared to dcSSc. The remaining nutritional markers were comparable between lcSSc and dcSSc. High disease activity, increased levels of CRP or ESR, worse skin involvement (higher mRSS), and lower BMI were associated with adverse changes in nutritional markers, especially decreased albumin, prealbumin, transferrin, minerals, and vitamins. Other factors significantly associated with nutrition parameters were the current dose of glucocorticoids, disease duration, lung involvement, and age (table 1).

Conclusion: We have observed significant alterations in nutritional parameters in our SSc patients compared to age-/sex-matched healthy individuals. These changes were associated predominantly with disease activity and skin involvement. Patients with dcSSc tended to have worse disease activity and more pronounced alterations of nutritional status compared to lsSSc patients.
