The collagenase secreted by Grimontia hollisae strain 1706B is a 74 kDa protein that consists of two parts: the catalytic module and a C-terminal segment that includes the bacterial pre-peptidase C-terminal domain. Here, we produced a recombinant C-terminal segment protein and examined its ability to bind collagen and other characteristics as compared with collagen-binding domains (CBDs) derived from Hathewaya histolytica ( Clostridium histolyticum ) collagenases; these CBDs are the only ones thus far identified in bacterial collagenases...

Dupuytren's contracture (DC) or Dupuytren's disease (DD) is a progressive fibro-proliferative disease of palmoplantar connective tissue, resulting in characteristic nodal and/or cord formation from collagen disposition. When the disease progresses, the thickening and shortening of the cords eventually leads the affected fingers to being pulled into flexion, which may be associated with marked disability, especially with bilateral disease. DD is relatively common in Europe, with the highest prevalence in Nordic countries...

BACKGROUND: Dupuytren's disease results in contracted cords in the hand that lead to deformity and disability. Current treatment options include fasciectomy and an injectable, collagenase clostridium histolyticum. No cost comparison studies have been published within the Australian health care environment. METHODS: A retrospective review of all patients treated for Dupuytren's disease in a major teaching hospital was undertaken to compare the costs of treatment by fasciectomy or collagenase injection...

We describe our injection method for Collagenase Clostridium Histolyticum using a medical silicone tube after determining the optimal depth by ultrasonography. This procedure adjusts the exposed needle length to the planned injection depth by placing a sterilized silicone tube over the needle. The restricted depth provides not only precise injection into the middle of the cords but also avoids needle tip migration through the cord and into the vital structures, which prevents possible complications. This method is safe and simple...

INTRODUCTION: In Switzerland, collagenase Clostridium histolyticum therapy (CCH) for Dupuytren's disease was introduced in 2011. This study analyzes possible differences between CCH and limited fasciectomy (LF) in terms of range of motion, patient satisfaction and postoperative rehabilitation. MATERIALS AND METHODS: This retrospective study included 52 patients with Dupuytren's disease stage 1-3 according to Tubiana, treated with CCH or LF between January 2012 and December 2013...

BACKGROUND: Collagenase clostridium histolyticum is now recognized as a viable treatment for Dupuytren disease. The high rate of adverse effects reported in patients continues to spark debate and raise questions about the true frequency of effects and their associated mechanisms of action. HYPOTHESIS: To investigate whether outcomes of CCH treatment are related to the number of adverse effects experienced. To evaluate short-term clinical outcomes in a series of patients...

Intralesional injection of collagenase clostridium histolyticum (CCH) improves Peyronie's disease (PD) symptoms; however, patient perspectives regarding PD and CCH treatment have not been fully elucidated. This cross-sectional qualitative study included heterosexual men with PD who received ≥1 injection of study medication and had ≥1 posttreatment Peyronie's Disease Questionnaire (PDQ) assessment during a prior phase 2b clinical trial. These patients were "responders" if they reported (as part of the Global Assessment of the PDQ) that overall symptoms and effects of PD had at least "improved in a small but important way" after CCH therapy...

Aims: Dupuytren's contracture is a benign, myoproliferative condition affecting the palmar fascia that results in progressive contractures of the fingers. Despite increased knowledge of the cellular and connective tissue changes involved, neither a cure nor an optimum form of treatment exists. The aim of this systematic review was to summarize the best available evidence on the management of this condition. Materials and Methods: A comprehensive database search for randomized controlled trials (RCTs) was performed until August 2017...

Dupuytren's contracture, a benign condition characterized by fibrosis of the palmar and digital fascia, may be a debilitating condition that limits daily function. Several techniques exist for managing symptomatic contractures of the hand related to Dupuytren's. These techniques include the more invasive open fasciotomy or fasciectomy. More recently, less invasive techniques including administration of collagenase Clostridium histolyticum (CCH) or percutaneous needle aponeurotomy (PNA) have become part of the treatment armamentarium...

PURPOSE: To explore the efficacy of injectable collagenase Clostridium histolyticum (CCH) in distal interphalangeal (DIP) joint contractures in Dupuytren disease. METHODS: A retrospective review was conducted for patients with DIP joint contractures treated with CCH. Baseline contracture and posttreatment residual contracture were recorded. The primary end point was achievement of 0° to 5° of residual contracture 30 days postmanipulation. Recurrence and adverse events are also reported...

Collagenase clostridium histolyticum (CCH) was approved for the treatment of Peyronie's disease (PD) in December of 2013. Recently, further research has supported its use. The aim of this study was to objectively evaluate the effects of CCH on penile curvature associated with Peyronie's disease at our high volume institution. Since the approval of CCH for PD, 45 men have undergone between 1 and 4 treatment cycles (mean 3.13, standard deviation (SD) = 0.87) at our institution. Primary as well as secondary curvature, if any, was measured before beginning therapy and after each cycle of therapy...

This study assesses the joint-specific sustained effect of collagenase clostridium histolyticum treatment of Dupuytren disease over a 5-year follow-up period. The study includes 107 consecutive treatments in patients with extension deficits greater than 20° affecting the metacarpophalangeal or proximal interphalangeal joints. Success was defined as no follow-up treatment due to relapse or maintained extension deficit less than 20°. The 5-year estimate of no follow-up treatment was 79% (95% CI: 64-88) for metacarpophalangeal and 49% (95% CI: 26-69) for proximal interphalangeal joints, which was a significant difference (log-rank test, p = 0...

OBJECTIVE: To compare in a prospective, non-randomized fashion the outcomes of Collagenase Clostridium Histolyticum (CCH) and surgical interventions (tunical plication [TP] and partial plaque excision and grafting [PEG]) in patients with PD. Intralesional injection of CCH is the only Food and Drug Administration-approved non-surgical intervention for Peyronie's disease (PD). MATERIALS AND METHODS: Between 6/2015 and 1/2017, 57 patients with PD and dorsal, dorsolateral and/or lateral penile curvatures 30-90 degrees were included in this study...

This post hoc analysis from a multicenter study (NCT01674634) was designed to evaluate the efficacy of collagenase Clostridium histolyticum (CCH) treatment in patients with different stages of Dupuytren contracture. Previously untreated patients who received two concurrent injections of CCH in two affected joints in the same finger were assessed by disease severity (Tubiana stage). The mean (SD) improvement in total fixed flexion contraction (FFC) 31 days post-CCH treatment in 181 patients was: 71.1 (36.5)% for Tubiana I, 77...

To penetrate host tissues, histotoxic clostridia secrete virulence factors including enzymes to hydrolyze extracellular matrix. Clostridium histolyticum, recently renamed as Hathewaya histolytica, produces two classes of collagenase (ColG and ColH). The high-speed AFM study showed that ColG collagenase moves unidirectionally to plane collagen fibril and rebundles fibril when stalled . The structural explanation of the roles for the tandem collagen-binding segment (CBDs) is illuminated by its calcium-bound crystal structure at 1...

Proof-of-principle, basic-science studies, using a rat-tail tendon model and surgically removed Dupuytren cords, began collagenase Clostridium histolyticum (CCH) development. Clinical studies in humans were then conducted, where the primary endpoint was reduction in contracture to within 0° to 5° of extension. Phase 2 studies, which confirmed the optimal dose of collagenase as 0.58 mg, showed injectable CCH reduced contractures in MP and PIP joints to within 0° to 5° in many joints and was well tolerated...
