Late Complications of Clinical Clostridium Histolyticum Collagenase Use in Dupuytren's Disease
Published: Friday, August 17, 2012
Author: Warren M. Rozen et al.

by Warren M. Rozen, Yasith Edirisinghe, John Crock

Introduction

While Dupuytren's disease can cause disabling contractures requiring open surgery, a less-invasive option using Clostridium Histolyticum collagenase (CHC) via percutaneous injection was recently reported. A recent prospective, randomized trial demonstrated few complications during 90 days follow-up, however did not assess any longer term follow-up for these patients. Long-term outcomes in this setting have not been adequately reported, and the current manuscript aims to identify late complications from the clinical use of percutaneous CHC.

Methods

The current manuscript reports an extended 12-month follow-up for a cohort of twelve of patients enrolled in the original prospective, randomized trial, treated at a single institution. An analysis of complications requiring surgical intervention was undertaken.

Results

Two of twelve patients reported debilitating pain and triggering requiring surgical intervention. Extensive deep-tissue scarring and adhesions were identified, providing the first visual and qualitative analysis of the pathologic effects of CHC.

Conclusion

Late complications from CHC use can and have occurred, outside the follow-up period of the initial phase III trials. Longer term follow-up of such patients is thus essential, and further investigation and characterization of the late effects of CHC use is warranted.
