abstract = {Background: An examination of potential racial variations between Caucasian American (CA) and African American (AA) men in the efficacy and safety of collagenase clostridium histolyticum (CCH) in the treatment of Peyronie’s disease (PD).
Methods: We retrospectively reviewed the records for all patients treated with CCH for PD between 04/2014 and 05/2017. Patients were divided into two groups based on their self-reported race. The primary outcomes of interest were final change in curvature after CCH treatment regardless of number of CCH cycles received, and frequency of treatment-related adverse events (TRAEs).
Results: A total of 159 patients were included in the study, of which 146 (91.8%) were CA while 13 (8.2%) were AA. Mean duration of PD was 28.3 months for CA patients and 16.8 months for CA patients (P=0.436). There was no significant difference in final change in curvature CA and AA patients (15.9° vs. 13.1° respectively, P=0.445). There was no statistically significant difference in frequency of TRAEs between CA patients (17, 12%) and AA patients (0, 0%) (P=0.208).
Conclusions: Although racial variations in efficacy and safety of CCH in patients with PD have not been addressed in the literature, preliminary results from our study suggest that CCH therapy may be equally efficacious and safe in both CA and AA men. There was no statistically significant difference in final change in curvature, International Index of Erectile Function (IIEF) scores, penile length, or TRAEs after CCH treatment between CA and AA patients.},
