In patients with SSc, malnutrition is common and not identified by BMI. BIA parameters reflect disease severity and provide best predictors for patient survival. Therefore, an assessment of nutritional status should be performed in patients with SSc.

ObjectiveIn this pilot study, the effect of sildenafil on digital ulcer (DU) healing and related clinical symptoms was analysed.MethodsA total of 19 patients with systemic sclerosis (SSc) were treated with maximally tolerated sildenafil doses up to 6 months. Primary outcome was the healing of DUs. Changes in other clinical symptoms were also evaluated.ResultsIn all, 49 DUs were present at baseline; this decreased to 17 ulcers (p<0.001) at the end of sildenafil treatment. Furthermore, the visual analogue scale (VAS) score for Raynaud's phenomenon (RP), pain and activity improved (p=0.003, p=0.002 and p=0.05, respectively). A total of 9 patients developed 12 new DUs during sildenafil treatment.ConclusionsThis study indicates an effect of sildenafil on DU healing in patients with SSc and an improvement of RP and associated symptoms that should be validated in controlled studies.

Detected by LIA, anti-CENP-A and anti-CENP-B antibodies show high concordance in patients with SSc and share significant associations to clinical manifestations, but are not completely identical. Detection of both antibodies in parallel may slightly increase the diagnostic sensitivity for SSc.
