WHEN FIBROSIS INTERSECT: ASSOCIATION AND RISK FACTORS BETWEEN PEYRONIE'S AND DUPUYTREN'S DISEASES.

Peyronie's and Dupuytren's diseases are benign but are source of significant functional impairment leading to considerable suffering. In this study, the aim is to investigate the association between Peyronie's and Dupuytren's diseases as well as their common and specific risk factors. From July 2022 to March 2024, we conducted a multicentric observational study on 450 patients. Patients followed up for Peyronie's and/or Dupuytren's disease were given a questionnaire that included a consent form, in order to screen one or the other associated disease and explore all risk factors. Among the 278 patients followed for Dupuytren's disease, 35 (12.3%) had Peyronie's disease. Of the 172 patients with initial Peyronie's disease, 50 (29.1%) were diagnosed with Dupuytren's disease. Eventually, 85 patients had both pathologies (18.9%). High blood pressure was significantly more prevalent in patients with both diseases, compared to subjects with Peyronie's disease only (37.7% vs. 38.4% vs. 24.4%; p=0.02). The same observation was made regarding smoking (62.3% vs. 60.7% vs. 48.8%; p=0.05) and daily alcohol consumption (52.9% vs. 41.7% vs. 35.8%; p=0.04). Patients diagnosed with isolated Dupuytren's disease were more likely to be diabetic (13.6% vs. 9.41%; p = 0.42). Blue eyes and family history were significantly more often reported in Dupuytren's patients (33.9% vs. 22.8%; p=0.03 ; p < 0.001). Ledderhose disease was significantly more prevalent in patients with both diseases or isolated Dupuytren's disease (21.2% vs. 12.4% vs. 3.3%; p=0.0003). This study confirms the association between Peyronie and Dupuytren diseases'. Smoking, alcohol daily consumption and hypertension are more prevalent in case of associated diseases. Blue eyes and family history are significantly more frequently found in case of Dupuytren's contracture. More powerful studies including a control group are necessary.
