Updated recommendations on the therapeutic role of extracorporeal shock wave therapy for peyronie's disease: systematic review and meta-analysis

A review of Peyronie's disease insurance coverage

Background

Peyronie's disease (PD) is a fibroproliferative disorder that causes an abnormal curve of the penis resulting in pain, discomfort, and erectile dysfunction with management options including correctional surgery, penile external/internal devices, shock wave therapy (SWT), intralesional Verapamil (IV), and collagenase Clostridium histolyticum injections.

Aim

To investigate the insurance coverage of these treatment options.

Methods

The authors performed a cross-sectional analysis of the top US insurance policies for coverage of PD. Companies were chosen based on their market share and enrollment. Their policies were identified through a Web-based search and telephone interviews, and the companies' medical necessity criteria were defined. The online policies were then re-examined for interval change 3 years later.

Outcomes

There are significant discrepancies for in coverage for the different modalities of Peyronie's treatment.

Results

Of the 100 companies examined, only 54% of companies had a policy that directly addressed the treatment coverage for PD. The most covered treatment was CCH injections with 37 companies providing unanimous coverage (n = 37, 100%). Within this category, all companies required a palpable plaque as a requirement. Additionally, external/internal devices were unanimous covered by 18 companies (n = 18, 100%). Surgical treatment was covered by eight companies with six companies denying coverage (n = 8 vs. n = 6, 57.1% vs. 42.9%). IV was covered by two companies. The least covered treatment option was SWT which was universally denied by 19 companies (n = 19, 100%).

Clinical Implications

Insurance coverage of PD should be aligned with current medical literature to better increase access to care.

Strengths & Limitations

This study is limited by the updated policies of insurance companies and future applicability. Additionally, this study assumes that a written policy will provide coverage and may overestimate the actual extent of coverage. Finally, this study only addressed some of the common treatment options of PD and did not expand on all possible treatment options.

Conclusion

Differing rates for modalities of treatment may present a barrier for patients to receive individualized and adequate treatment for PD.

Research advances in Peyronie's disease: a comprehensive review on genomics, pathways, phenotypic manifestation, and therapeutic targets

INTRODUCTION

Penile induration disease, commonly known as Peyronie's disease (PD), is a connective tissue disorder that affects the penis, leading to the development of fibrous plaques, penile curvature, and erectile dysfunction. PD is a common male reproductive system disease with a complex etiology involving multiple genes, signaling pathways, and different phenotypes.

OBJECTIVES

The etiology and pathogenesis of PD remain poorly understood, hindering the development of effective treatment strategies. By understanding the underlying mechanisms of PD, we can pave the way for targeted therapies and improved patient outcomes.

METHODS

We reviewed the epidemiology and pathophysiology of PD. We performed database searches on Google Scholar, PubMed, Medline, and Web of Science from inception to September 2023. The literature reviewed included priapism guidelines, review articles, current trial studies, and various literature related to PD.

RESULTS

This article provides a comprehensive overview of the current research progress on the disease, focusing on its genetic factors, signaling pathways, cellular mechanisms, phenotypic manifestations, and therapeutic targets. It can help identify individuals at higher risk, aid in early detection and intervention, and provide insights into fibrosis and tissue remodeling. It can also reveal potential therapeutic targets, guide accurate diagnoses and treatment strategies, and address the impact of the disease on patients' quality of life.

CONCLUSION

By integrating insights from genomics, molecular pathways, clinical phenotypes, and therapeutic potentials, our research aims to achieve a deeper and more comprehensive understanding of PD, propelling the field toward innovative strategies that enhance the lives of those affected by PD. The complex manifestations and pathogenesis of PD necessitate the use of multiple treatment methods for personalized care.

The pathogenic role of the immune system in erectile dysfunction and Peyronie's disease: focusing on immunopathophysiology and potential therapeutic strategies

INTRODUCTION

Erectile dysfunction (ED) represents the major cause of male sexual dysfunction, which is often associated with obesity, diabetes mellitus, atherosclerotic cardiovascular disease, and cigarette smoking. Peyronie's disease is a chronic disorder associated with irreversible fibrotic damage of the tunica albuginea leading to ED, painful erection, coital disturbance, and physical and social complaints. Both conditions are characterized by chronic inflammation, oxidative stress, and significant changes in intracavernous hydrodynamics. In this scenario, oxidized lipoproteins, M1-polarized macrophages, proinflammatory cytokines (such as the tumor necrosis factor α), endothelial nitric oxide synthase, penile smooth muscle cells, and toll-like receptors represent the main triggers of the inflammatory process in ED. Phosphodiesterase-5 inhibitors are the most common treatment for ED. This treatment is used intermittently, as it is conceived as a symptomatic and not curative therapy. Moreover, not all patients respond to phosphodiesterase-5 inhibitors (35%-85%), particularly those with dysmetabolic phenotypes. Additional or alternative treatments are therefore desirable, mostly in refractory cases.

OBJECTIVES

In this review, we describe the immune-mediated pathogenesis of ED and Peyronie's disease (PD). In our literature search we placed particular emphasis on potentially practical therapeutic approaches, including natural products (such as polyphenols), due to their anti-inflammatory and antioxidant activities, stem cell therapy, and platelet-derived preparations.

METHODS

We searched PubMed/MEDLINE, Web of Science, Scopus, Cochrane Library, Google Scholar, and institutional websites. Original studies, narrative reviews, systematic reviews, and meta-analyses written in English were searched, screened, and selected.

RESULTS

In animal models of ED and PD, therapeutic approaches, including anti-inflammatory and antioxidant agents, stem cell therapy, and platelet-derived preparations, have provided positive results, including improved penile function, reduced inflammation and oxidative stress, and promotion of tissue repair. However, clinical evidence of improvement in human patients is still insufficient.

CONCLUSION

Promising results for treating ED and PD have been shown in preclinical and pilot clinical studies, but specific clinical trials are needed to validate the efficacy of these therapeutic approaches in men with ED.

Pain-Relieving Effects of Shockwave Therapy for Ledderhose Disease: An Ultrasound-Based Study of an Unusual Bilateral Case

Ledderhose disease (LD, or plantar fibromatosis) is a rare, nodular, hyperproliferative condition affecting the plantar aponeurosis of the foot. At present, several conservative, non-surgical treatments have been documented, although with various degrees of success, with little evidence in the literature supporting their efficacy. In this scenario, extracorporeal shock wave therapy (ESWT) has emerged as a safe, effective, and less invasive approach for the successful treatment of several refractory musculoskeletal conditions and soft tissue injuries. Again, recent experimental evidence has shown that ESWT can exert beneficial effects on different fibroproliferative diseases, including Dupuytren's and Peyronie's disease. In contrast, the literature regarding the use of ESWT for LD is extremely limited, and no optimal application parameters have been defined to ensure its effectiveness for this disease. Therefore, in the present paper, we report a case of a 48-year-old male patient who developed bilateral foot LD, which was successfully treated with a novel ESWT protocol of treatment consisting of three sessions at 1-week intervals, with 2000 impulses at 5 Hz with an energy flux density of 0.20 mJ/mm2. Our data show that this ESWT treatment protocol was effective in completely relieving pain, restoring full functional activity, and thus, greatly improving the patient's quality of life.
