BACKGROUND: Capsular contracture remains the most frequent long-term complication after augmentation mammoplasty with silicone implants. Thereby, the main part of the fibrotic capsule is collagen. The collagenase of the bacterium Clostridium histolyticum is approved for the treatment of fibrotic diseases and has been demonstrated to be effective for capsular fibrosis treatment in the short term. However, long-term effectiveness is currently unknown but mandatory for clinical utilization...

The introduction of collagenase Clostridium histolyticum (CCH) as a treatment option for Peyronie's disease (PD), defined as the abnormal formation of collagen on the tunica albuginea of the penis, has provided patients with a promising new conservative therapy. Studies have shown that CCH improves curvature by an average of 17°, and although patient and sexual partner satisfaction is high, the improvement has arguable clinical implications. Similarly, the efficacy and cost of CCH contrasts strongly with more invasive surgical management, and is further limited by rare, but serious, complications and several contraindications...

Dupuytren's disease is a connective tissue disorder leading to contractures. It can be treated surgically or through injections of collagenase Clostridium histolyticum (CCH). Patients with Dupuytren's contracture (> 20°) and a palpable cord were included in this observational study, aiming to characterise the Belgian patient population and to assess the effectiveness and safety of CCH. Overall, 108 patients (114 joints) received at least one injection of CCH, and 104 patients completed the study. The percentages of joints achieving a degree of contracture of 5° or less, or a relative contracture reduction of at least 50% after the extension procedure were 64...

Bacterial collagenases differ considerably in their structure and functions. The collagenases ColH and ColG from Clostridium histolyticum and ColA expressed by Clostridium perfringens are well-characterized collagenases that cleave triple-helical collagen, which were therefore termed as ´true´ collagenases. ColA from Bacillus cereus (B. cereus) has been added to the collection of true collagenases. However, the molecular characteristics of B. cereus ColA are less understood. In this study, we identified ColA as a secreted true collagenase from B...

INTRODUCTION: Since Dupuytren's contracture is a common disorder, the costs for its surgical treatment impose a considerable burden on the healthcare system. For the first time in the German-speaking area, this study aimed to provide a comparative cost-effectiveness analysis for partial fasciectomy vs. treatment with Clostridium histolyticum collagenase (CCH). METHODS: A retrospective monocentric study of the period from 2012 to 2014 comprised 40 patients with previously untreated Dupuytren's contracture of one finger...

Dupuytren's disease (DD) is a common fibroproliferative condition of the hand which tends to cause progressive digital flexion contracture. Therapeutic strategies to treat the disease include radiotherapy, injections of collagenase clostridium histolyticum, needle fasciotomy and extended surgical intervention dependent on involvement and duration of the disease. We have reviewed the literature with the aim to assess the conditions and effects of radiotherapy in DD. In early stages of the disease, radiotherapy resulted in regression of symptoms/a lack of progression found on average in 40% (range 10-85%)/81% (range 50-100%) of the patients with recurrence rates of only 12-31% after long-term follow-up (>4 years)...

Bacterial collagenases involved in donor infection are widely applied in many fields due to their high activity and specificity; however, little is known regarding the mechanisms by which bacterial collagenases degrade insoluble collagen in host tissues. Using high-speed atomic force microscopy, we simultaneously visualized the hierarchical structure of collagen fibrils and the movement of a representative bacterial collagenase, Clostridium histolyticum type I collagenase (ColG), to determine the relationship between collagen structure and collagenase movement...

BACKGROUND: Conducting research on the molecular biology, immunology, and physiology of brain tumors (BTs) and primary brain tissues requires the use of viably dissociated single cells. Inadequate methods for tissue dissociation generate considerable loss in the quantity of single cells produced and in the produced cells' viability. Improper dissociation may also demote the quality of data attained in functional and molecular assays due to the presence of large quantities cellular debris containing immune-activatory danger associated molecular patterns, and due to the increased quantities of degraded proteins and RNA...

OBJECTIVES: Peyronie's disease (PD) is a connective tissue disorder resulting in the abnormal accumulation of scar or plaques in the tunica albuginea of the penis. The condition is characterized by two phases: an active, inflammatory phase, and a stable, chronic phase. Collagenase Clostridium histolyticum (CCH) was isolated in the mid-1900s and postulated as a potential pharmacologic strategy for breaking down the abnormal connective tissue plaques of PD. Prior to the introduction of CCH, a wide variety of treatment modalities for PD were used in clinical practice, including oral and topical medications, intralesional injections, electromotive drug administration, extracorporeal shockwave therapy, traction, and invasive surgery, all with variable results...
