Faecal calprotectin is stable over time in systemic sclerosis
Typical FC level
Variability of FC over time Normal Elevated Substantially elevated All patients, n (%)
FC < 50, n FC = 50-200, n FC >200, n
Cohort A, n = 57
Solida 6 7 6 19 (33)
Stableb 3 18 12 33 (58)
Inconclusivec 0 4 1 5 (9)
All patients 9 29 19 57 (100)
Cohort B, n = 28

aAll FC measures fall into the same category; ball FC measures fall into the same category except 1 that is 1 step lower/higher; cthe FC measures show higher variability than above. Stool samples were delivered for analysis of FC at three (Cohort A) or four (Cohort B) time points and FC was categorised as solida, stableb or inconclusivec. FC: faecal calprotectin measured in μg/g.
