BACKGROUND: Pyoderma Gangrenosum (PG) is a chronic disease characterized by recalcitrant skin ulcers. OBJECTIVE: We aimed to evaluate the demographic, clinical characteristics, treatments and factors affecting the treatment responses of patients with PG. METHODS: We performed a multicenter study of 12 tertiary care centers. We analyzed the data of the patients who were followed up with a diagnosis of PG between the years 2012‒2022 retrospectively. RESULTS: We included a total of 239 patients of whom 143 were female and 96 were male, with an average age of 54.2 ± 17.4 years. The most common treatment was systemic steroids (n = 181, 75.7%). Among these patients, 50.8% (n = 92) used systemic steroids as the sole systemic agent, while 49.2% (n = 89) used at least one adjuvant immunosuppressive agent. The independent factors determined in regression analysis to influence response to systemic steroids positively were disease onset age ≥ 30-years, negative pathergy, absence of leukocytosis, negative wound culture, presence of a single lesion, and absence of upper extremity involvement. Biological agents were used in 18.4% (n = 44) of the patients in the present study. We also analyzed pathergy positive PG and early onset (onset age < 30) PG separately due to their distinct clinical features which were revealed during statistical analysis. STUDY LIMITATIONS: Retrospective nature of the present study. CONCLUSIONS: Analyses of the factors influencing treatment responses are addressed i...
