Long-term clinical outcome of collagenase clostridium histolyticum treatment is independent of Dupuytren Diathesis Score.

Abstract

Collagenase clostridium histolyticum (CCH) is a pharmaceutical, non-surgical treatment option for Dupuytren Disease. However, recurrence is common, and predictors of treatment outcome of CCH treatment are largely unknown. In this retrospective study, we analysed the possible correlation between Abe's Dupuytren Diathesis Score (DDS) and recurrence after treatment with CCH. In a total of 74 patients, with an average follow-up of 5 years, we found an overall recurrence rate of 67% after 5y but no correlation with DDS. Sub-scale analysis indicated that the presence of knuckle pads was associated with a reduced recurrence risk. Patient satisfaction after CCH was high. Deriving from our data, there is no correlation between DDS and recurrence following CCH treatment. Therefore, at this moment, we do not advocate the use of the DDS when informing patients about recurrence rates after CCH treatment. Level of evidence: IV: therapeutic cohort study.
