Collagenase Clostridium Histolyticum for the Treatment of Dupuytren Disease: A Delphi-Based Consensus Study

Purpose

The aim of this study was to establish the consensus recommendations among hand surgeons who were experts in the use of collagenase clostridium histolyticum (CCH) on the appropriate treatment of Dupuytren disease in well-defined patient populations with varying degrees of disease severity and functional impairment.

Methods

A three-round, blinded, modified Delphi process examined panelists' approaches to CCH treatment of metacarpophalangeal (MP) or proximal interphalangeal (PIP) joint contractures involving one or two fingers with varying degrees of severity. Clinical scenarios related to poor-quality skin, postfasciectomy scarring, boutonnière deformity, closed capsulotomy, and blood thinner use were also presented for panelist consideration. Panelists provided responses to clinical scenarios using a 5-point Likert scale or a yes/no response. Consensus was defined as ≥66.7% panelist agreement or disagreement.

Results

Twenty panelists completed round 1; 19 of the 20 panelists completed rounds 2 and 3. Panelists achieved a high level of consensus for using CCH for the treatment of patients with palpable cords and varying severity contractures representing one- or two-finger MP joint contractures, most one- or two-finger PIP joint contractures, and most combined MP and PIP joint contractures. Consensus for the treatment of PIP joint contractures was mostly achieved, but clinical scenarios related to recurrent PIP contracture with poor-quality skin and/or significant postfasciectomy scarring, boutonnière deformity, PIP contractures >70°, closed capsulotomy, and blood thinner use were modified, and then most (95.3%) statements reached consensus for agreement in round 2. In round 3, open-ended responses indicated that panelists considered CCH appropriate for most patients with Dupuytren disease.

Conclusions

Consensus-based findings among expert hand surgeons with substantial CCH experience indicated that CCH has a wide-ranging application for the treatment of Dupuytren disease in patients with varying degrees of disease severity and functional impairment.

Full-thickness skin grafting in preventing recurrence of Dupuytren's disease: A systematic review

Dupuytren's disease is a progressive hand disorder characterized by the formation of pathologic nodules and cords in the palm, often leading to progressive flexion contractures. Hand surgery is currently the only efficient treatment to restore hand function, however, reported recurrence rates vary widely. Currently, it remains unclear which type of fasciectomy is associated with the lowest recurrence rate. Therefore, a systematic review was conducted to compare recurrence rates after limited fasciectomy, open palm technique, or dermofasciectomy with a full-thickness skin graft. 79 studies were included, and results suggest that a dermofasciectomy with a full-thickness skin graft is associated with a lower recurrence rate. However, most studies were case series in which a wide range of definitions of recurrence was used. Moreover, all studies had a high risk of bias. Therefore, additional comparative clinical trials are recommended that use an unambiguous definition of recurrence. LEVEL OF EVIDENCE III: .

Dupuytren's disease: my personal view

Dupuytren's disease is a heterogenous condition for which a palette of treatment options is required. Randomized control trial evidence is sparse; design challenges, such as validated outcome measures, blinding, equipoise, funding and assessment of recurrence, may limit further data accrual. Recurrence has different significance with different treatments and so rates are not directly comparable. The risk of any treatment is a function of both the chance of a complication and the clinical sequelae of that complication. The patient must be intimately involved in choosing treatment and is often trading rapid recovery for a higher chance of recurrence. Health economies are strained and as custodians of healthcare, surgeons should consider whether many patients even need treatment. To minimize the chance of complex, hazardous and expensive revision surgery, a low threshold for primary skin grafting should be applied, especially for those who are young, have dense disease or vulnerable genes.

Efficacy and safety of collagenase clostridium histolyticum for Dupuytren disease nodules: a randomized controlled trial

Background

To determine the safety and efficacy of collagenase clostridium histolyticum (CCH) injection for the treatment of palmar Dupuytren disease nodules.

Methods

In this 8-week, double-blind trial, palpable palmar nodules on one hand of adults with Dupuytren disease were selected for treatment. Patients were randomly assigned using an interactive web response system to receive a dose of 0.25 mg, 0.40 mg, or 0.60 mg (1:1:1 ratio) and then allocated to active treatment (CCH) or placebo (4:1 ratio). All patients and investigators were blinded to treatment. One injection was made in the selected nodule on Day 1. Caliper measurements of nodule length and width were performed at screening and at Weeks 4 and 8. Investigator-reported nodular consistency and hardness were evaluated at baseline and Weeks 1, 4, and 8. Investigator-rated patient improvement (1 [very much improved] to 7 [very much worse]) and patient satisfaction were assessed at study end.

Results

In the efficacy population (n = 74), percentage changes in area were significantly greater with CCH 0.40 mg (−80.1%, P = 0.0002) and CCH 0.60 mg (−78.2%, P = 0.0003), but not CCH 0.25 mg (−58.3%, P = 0.079), versus placebo (−42.2%) at post-treatment Week 8. Mean change in nodular consistency and hardness were significantly improved with CCH versus placebo at Weeks 4 and 8 (P ≤ 0.0139 for all). At Week 8, investigator global assessment of improvement was significantly greater with CCH 0.40 mg and 0.60 mg (P ≤ 0.0014) but not statistically significant with CCH 0.25 mg versus placebo (P = 0.13). Most patients were “very satisfied” or “quite satisfied” with CCH 0.40 mg and 0.60 mg. Contusion/bruising (50.0% to 59.1%) was the most common adverse event with CCH treatment.

Conclusion

In patients with Dupuytren disease, a single CCH injection significantly improved palmar nodule size and hardness. The safety of CCH was similar to that observed previously in patients with Dupuytren contracture.

New insights into the immediate outcome of collagenase injections for Dupuytren's contracture

Collagenase clostridium histolyticum is now established as an effective and safe option to treat patients with a single joint affected with Dupuytren's contracture. We have extended its use to natatory and combined cords. In a prospective consecutive series of 298 cords in 237 patients, the mean total extension loss improved in cords crossing the metacarpophalangeal joint from 46° to 1°, in cords crossing the proximal interphalangeal joint from 56° to 7°, in natatory cords from 130° to 25° and in combined cords from 102° to 16°. The immediate correction of combined cords and natatory cords was less reliable than that obtained in cords crossing the metacarpophalangeal joint or proximal interphalangeal joint. Less severe pre-intervention contractures tended to correct better. We found a high complication rate, which may cause alarm. A total of 21% developed skin splits, with the risk of skin splits generally increasing with more severe pre-injection deformity. Blood blisters were only encountered after manipulation of the more severe contractures. A total of 23 patients (8%) had a spontaneous rupture and 57 patients (19%) had a partial spontaneous rupture. Only 4.9% needed a second injection. We noticed a learning curve, with seven of the first 20 cords (35%) needing a second injection to achieve a satisfactory correction and then only seven (2.5%) in the rest.

Needle aponeurotomy for the treatment of Dupuytren's disease

PNA is one of many treatments available for the treatment of hand contractures resulting from Dupuytren’s disease. It is generally recommended for elderly patients with less severe contractures who desire a less invasive procedure, or as a first stage to delay surgery in those with more aggressive disease. The procedure is safe and easily tolerated by patients, but there is a high rate of recurrence.
