Abstract
The clinical landscape of Peyronie's disease is everchanging. There has been growing interest in non-invasive therapeutic options that could assist patients with achieving a meaningful reduction in penile curvature without surgical intervention. These therapies are wide-ranging in terms of their mechanisms of action, efficacies, and short- and long-term safety profiles. Recently, an abundance of outcomes literature on longstanding and novel non-surgical treatment modalities has been published. For sexual medicine providers hoping to offer patients the most up-to-date and evidence-based treatments for the management of Peyronie's disease, it can be challenging to gain a thorough understanding of this body of literature. In this clinical management review, the workup and current theories on the pathophysiology of Peyronie's disease are reviewed, and the most recent outcomes data on the currently available non-surgical treatment modalities are presented. With an accurate understanding of the current landscape of Peyronie's disease treatment, sexual health providers will be able to better evaluate and engage in evidence-based shared decision-making with their patients.

The efficacy and safety of intralesional injection of collagenase Clostridium histolyticum for Peyronie’s disease: A meta-analysis of published prospective studies. Front Pharmacol 2022; 13:973394. [DOI: 10.3389/fphar.2022.973394] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Accepted: 09/12/2022] [Indexed: 11/13/2022] Open
Abstract
Background: Peyronie’s disease (PD) is a progressive fibrotic disorder of the penis that is adverse to men’s health. Currently, effective and reliable non-surgical options for PD are limited. Since the Food and Drug Administration (FDA) approved it in 2013, intralesional injection of collagenase Clostridium histolyticum (CCH) became the only licensed treatment for PD. This meta-analysis aims to evaluate the clinical efficacy and safety of CCH in treating PD, predominantly based on post-FDA studies.Methods: The primary outcome was clinical efficacy evaluated by the percentages of improvement in penile curvature (PC) and Peyronie’s disease symptom bother score (PD bother score). The secondary outcome was the safety assessed by treatment-related adverse events (TRAEs). Heterogeneity was assessed by Cochran’s Q and I2 tests. Sensitivity and subgroup analyses were performed to explore the source of heterogeneity. Funnel plots and Egger’s test were used to evaluate the publication bias.Results: A total of 11 studies with 1,480 intentions to treat (ITT) population were included. The pooled effect of the improvement of PC was 35% (95% CI: 0.33–0.38), and the pooled improvement of the PD bother score was 41% (95% CI: 0.37–0.45). No heterogeneity was found at the pooled improvement of PC (p = 0.845, I2 = 0.00%). Meanwhile, some heterogeneity existed in the pooled improvement of the PD bother score (p = 0.069, I2 = 43.4%). The pooled effect of TRAEs was 93% (95% CI 0.88–0.97) with significant heterogeneity (p < 0.000, I2 = 92.3%).Conclusion: The intralesional injection of CCH could significantly improve the penile deformity of PD patients. Meanwhile, CCH appears to ameliorate the PD bother score to some extent and has acceptable clinical safety. Future studies are required to clarify the long-term outcomes of CCH injection in the treatment of PD.

Abstract
BACKGROUND The objective of this study was to evaluate the efficacy of subacromial injections of collagenase and corticosteroid in rats with experimentally induced adhesive capsulitis. METHOD Thirty adult Wistar albino male rats were distributed into 3 groups of 10 rats each after stabilization of their shoulders for 3 weeks: the first group received a single dose of 0.002 mg (0.25 mL) subacromial collagenase; the second group received a single dose of 1.60 mg (0.25 mL) subacromial steroid, and the third group received a single dose of 0.25 mL subacromial saline solution. One week later, we investigated shoulder range of motions, collagen content of the shoulder, and joint cartilage structure. RESULTS There was no statistically significant difference in the cartilage damage between the groups (p > 0.05). Fibrosis measurements were significantly lower in the collagenase group than in the steroid and saline groups. There was no significant difference in fibrosis between the steroid and saline groups (p > 0.05). Abduction measurements were significantly higher in the collagenase group than in the steroid and saline groups (p < 0.001). No significant difference in the abduction measurements was observed between the saline and steroid groups (p > 0.05). CONCLUSION We observed that subacromial injections of collagenase Clostridium histolyticum effectively treated adhesive capsulitis. The results suggest that this treatment could be considered for use in patients with an intact rotator cuff.

World J Mens Health 2017; 35:134-145.

Abstract
Peyronie's disease (PD) is an inflammatory disorder characterized by an abnormal collagen deposition in the tunica albuginea of the penis, leading to fibrous and non-compliant plaques that can impede normal erection. Although pharmacological treatments are available, only intralesional injection therapy and surgical reconstruction have demonstrated tangible clinical efficacy in the management of this condition. Intralesional injection of collagenase clostridium histolyticum (CCH) has come to the forefront of minimally invasive treatment of PD. In this review, the authors provide an update on the safety, efficacy, and indications for CCH. The efficacy of CCH will be assessed on the basis of improvement in the severity of penile fibrosis, curvature, and pain. Numerous well-designed clinical trials and post-approval studies involving more than 1,500 patients have consistently demonstrated the efficacy and tolerability of CCH in the treatment of PD. CCH significantly decreases penile curvature and plaque consistency, as well as improves quality of life. Post-approval studies continue to demonstrate the efficacy of CCH despite broader inclusion criteria for treatment, such as the case with acute phase disease and atypical plaque deformities (i.e., ventral plaques, hourglass narrowing). CCH continues to be the gold standard for non-surgical management of stable phase PD, in the absence of strong evidence supporting oral therapy agents and ongoing evaluation of extracorporeal shockwave therapy. However, recent studies are beginning to provide precedent for the use of CCH in the management of acute phase and atypical PD.

Cloning, Purification and Characterization of the Collagenase ColA Expressed by Bacillus cereus ATCC 14579. PLoS One 2016; 11:e0162433.

Abstract
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. cereus ATCC 14579, which is transcriptionally controlled by the regulon phospholipase C regulator (PlcR). B. cereus ATCC 14579 ColA was cloned to express recombinant wildtype ColA (ColAwt) and mutated to a proteolytically inactive (ColAE501A) version. Recombinant ColAwt was tested for gelatinolytic and collagenolytic activities and ColAE501A was used for the production of a polyclonal anti-ColA antibody. Comparison of ColAwt activity with homologous proteases in additional strains of B. cereus sensu lato (B. cereus s.l.) and related clostridial collagenases revealed that B. cereus ATCC 14579 ColA is a highly active peptidolytic and collagenolytic protease. These findings could lead to a deeper insight into the function and mechanism of bacterial collagenases which are used in medical and biotechnological applications.
