Complete Plaque Regression in Patients with Peyronie’s Disease After Multimodal Treatment with Antioxidants: A Report of 2 Cases

Measurement of Oxidative Stress Index (OSI) in Penile Corpora Cavernosa and Peripheral Blood of Peyronie's Disease Patients: A Report of 49 Cases

Peyronie's disease (PD) is a chronic inflammatory disease affecting the penile albuginea. Oxidative stress (OS) is important for the development of the disease; therefore, it seemed interesting to us to directly measure OS at both the site of the disease and in peripheral blood. For a precise OS study, it is necessary to evaluate not only the single results of the total oxidant status (TOS) and total antioxidant status (TAS) but also their ratio: OS index (OSI) (arbitrary unit) = TOS/TAS × 100. This study included 49 PD patients examined and diagnosed in our Peyronie's care center and a control group of 50 cases. We collected blood samples from both the penis and a vein in the upper extremity; we used d-ROMs and PAT-test (FRAS kit) for OS measurement. Pearson's study found a statistical correlation between penile OSI values and PD plaque volumes: p-value = 0.002. No correlation was found between systemic OSI values and PD plaque volumes: p-value = 0.27. Penile OSI values were significantly reduced after the elimination of the PD plaque (p < 0.00001). The mean value of the penile OSI indices in the PD patients after plaque elimination corresponded to 0.090 ± 0.016 (p = 0.004). The comparison between the penile OSI values of the PD patients (with plaque elimination) and the control group revealed no statistically significant differences (p = 0.130). The absence of a correlation between Peyronie's plaque volume and systemic OSI values indicates that it is preferable to carry out the OS study by taking a sample directly from the site of the disease. By carrying out a penile OSI study, it would be possible to obtain a precise plaque-volume-dependent oxidative marker. Even if the study did not demonstrate any correlation between OSI indices and anxious-depressive state, we detected a high prevalence of anxiety (81.6%) and depression (59.1%) in PD patients.

Role of Oxidative Stress in Peyronie's Disease: Biochemical Evidence and Experiences of Treatment with Antioxidants

BACKGROUND

Peyronie's disease (PD) is a chronic inflammatory condition affecting adult males, involving the tunica albuginea of the corpora cavernosa of the penis. PD is frequently associated with penile pain, erectile dysfunction, and a secondary anxious-depressive state. The etiology of PD has not yet been completely elucidated, but local injury is generally recognized to be a triggering factor. It has also been widely proven that oxidative stress is an essential, decisive component in all inflammatory processes, whether acute or chronic. Current conservative medical treatment comprises oral substances, penile injections, and physical therapy.

AIM

This article intends to show how antioxidant therapy is able to interfere with the pathogenetic mechanisms of the disease.

METHOD

This article consists of a synthetic narrative review of the current scientific literature on antioxidant therapy for this disease.

RESULTS

The good results of the antioxidant treatment described above also prove that the doses used were adequate and the concentrations of the substances employed did not exceed the threshold at which they might have interacted negatively with the mechanisms of the redox regulation of tissue.

CONCLUSIONS

We believe new, randomized, controlled studies are needed to confirm the efficacy of treatment with antioxidants. However, we consider the experiences of antioxidant treatment which can already be found in the literature useful for the clinical practice of urologists in the treatment of this chronic inflammatory disease.

Disappearance of Plaque Following Treatment with Antioxidants in Peyronie's Disease Patients-A Report of 3 Cases

Peyronie's disease (PD) is a fibrotic disorder of the penile tunica albuginea. To date, only a few cases of recovery from PD following medical treatment have been reported in the literature. In this article, we describe three new cases of PD where patients achieved complete resorption of plaque following multimodal antioxidant treatment. In all three cases, treatment included the following antioxidants: bilberry, propolis, ginkgo biloba, silymarin, and vitamin E. Only in case nos. 1 and 2 did we also use the following antioxidant substances: L-carnitine, coenzyme Q10, and Boswellia. In all three cases, we also used a local therapy with diclofenac gel. Only in case no. 2 did we also use periodic perilesional injections with pentoxifylline. Although the sample of cases presented here was small, these patients incontrovertibly experienced complete plaque disappearance and recovery (in one case, only after a short course of treatment). Therefore, it is our conviction that urologists may find our experiences of considerable interest in their clinical practices.

Patients with Peyronie's disease achieve complete plaque regression after multimodal treatment with antioxidants: a case series

BACKGROUND

Peyronie's disease is a chronic inflammatory condition of the corpora cavernosa characterized by the formation of plaque in the tunica albuginea, which results in penile deformity. Conservative medical approaches encompass oral, topical, and physical treatment. Only two cases of patients with Peyronie's disease with complete plaque regression after treatment have been described in literature.

CASE PRESENTATION

Case 1: A 50-year-old Caucasian man with penile pain and double penile curvature of 5° (left ventrolateral), palpable nodule, and normal penile rigidity. The patient underwent multimodal therapy (oral antioxidants + topical diclofenac gel). At follow-up after over 4 years of treatment, the patient no longer complained of any penile deformity or pain. Ultrasound examination did not show any plaque. Case 2: A 26-year-old Caucasian man with lateral-right penile curvature of 30° (previous congenital curvature of 15°), palpable nodule, and normal penile rigidity. The patient underwent multimodal therapy (oral antioxidants + topical diclofenac gel + penile injections/pentoxifylline). After 28 months of treatment, the patient presented a lateral right curve of 15° at follow-up, similar to the original congenital penile curvature. Ultrasound examination no longer showed any plaque. Case 3: A 36-year-old Caucasian man with penile pain and a complex penile curvature of 15° and 20° (left dorsolateral), palpable nodule, and normal penile rigidity. The patient underwent multimodal therapy (oral antioxidants + topical diclofenac gel + penile injections/pentoxifylline). At follow-up after 28 months of treatment, the patient presented a dorsal curve (10°) similar to the original congenital curvature. Penile palpation did not detect any nodules, and ultrasound no longer showed any plaque.

CONCLUSIONS

This study demonstrates that our multimodal therapy is able to completely regress plaque, as demonstrated in our previously published article. Peyronie's disease has the potential to be treated conservatively with good results. However, this method of treatment needs to be combined with accurate ultrasound assessment, performed using a sufficiently advanced machine by an experienced operator.

Full Regression of Peyronie’s Disease Plaque Following Combined Antioxidant Treatment: A Three-Case Report

Peyronie’s disease (PD) is a fibrotic disorder of the tunica albuginea of the penis. Conservative medical therapy includes oral and/or injective active substances. Until now, only two PD patients who recovered after medical treatment are described in the literature. This article describes three new cases of PD patients who achieved complete resorption of plaque following antioxidant treatment. Case Presentations: Case 1. The patient was a 34-year-old man, a smoker, with lateral-left penile curvature (40 degrees), penile pain, and good penile rigidity. The patient was treated with combined therapy (oral antioxidants + Propolis creme). At follow-up, after about 29 months of treatment, we observed the disappearance of the acquired penile deformity. The ultrasound examination no longer showed any plaque. Case 2. The patient was a 32-year-old man with chronic prostatitis, penile lichen sclerosus, lateral-left penile curvature (10 degrees), a palpable lump, and good penile rigidity. The patient was treated with combined therapy (oral antioxidants + Propolis creme + penile injections of pentoxifylline). After 33 months of treatment, at follow-up, we observed the disappearance of the penile deformity. Ultrasound examinations no longer showed any plaque. Case 3. The patient was a 33-year-old man with penile pain, dorsal penile curvature (30 degrees), and good penile rigidity. The patient was treated with combined therapy (oral antioxidants + Propolis creme + penile injections of pentoxifylline). At follow-up, after 41 months of treatment, the penile pain was no longer present, and the ultrasound study no longer showed any plaque. Conclusions: Although our study presents a limited number of cases, it is a matter of fact that these patients obtained full regression in the affected area. We believe our experience may be very useful for urological clinical practice.
