Abstract

Objectives: Urinary tract involvement is a seldom-reported manifestation of SSc that could compromise patients' quality of life. This study compares lower urinary tract symptoms (LUTS) in SSc patients and in healthy subjects and their association with clinical and diagnostic parameters.

Methods: LUTS were assessed through self-reported questionnaires in 42 SSc patients and 50 matched healthy subjects. Statistical analyses were performed to explore LUTS in the two populations and their association with SSc variables, including nailfold videocapillaroscopy patterns, SSc-related antibodies and DXA parameters.

Results: SSc patients showed significantly higher prevalence and severity of urinary incontinence (UI) and overactive bladder (OAB) than healthy controls (P < 0.005, P < 0.01). SSc was a strong predictor of LUTS, independent of demographic data, comorbidities and treatments (odds ratio 5.57, 95% CI 1.64-18.88). In SSc patients OAB positively correlated with sarcopenia (P < 0.001), and both OAB and UI significantly correlated with reduced BMD (P < 0.05, P = 0.001). UI positively correlated with Scl70 antibodies (P < 0.05) and ciclosporin treatment (P = 0.001) and negatively with RNA polymerase III antibodies (P < 0.05); OAB positively correlated with calcinosis (P < 0.005) and negatively with methotrexate treatment (P < 0.05). Nailfold videocapillaroscopy 'active' and 'late' patterns were predominant among SSc patients presenting urinary symptoms, although no statistical correlation was found.

Conclusion: For the first time urinary tract involvement was found to be significantly higher in SSc patients than in healthy matched controls. In addition, sarcopenia, bone damage and calcinosis appeared significantly correlated with LUTS, suggesting a possible interplay.
