EPIDEMIOLOGICAL ASPECTS OF DUPUYTREN'S DISEASE IN BRAZIL.

Objectives: The purpose of this study is to describe associated factors and epidemiological aspects of Dupuytren's Disease in patients followed up in a Brazilian tertiary public hospital, at the Hand Surgery service. Methods: A cross-sectional study was performed from 2014 to 2019. Data collected included: age, gender, ancestry, associated comorbidity presence, phenobarbital, tobacco, and alcohol use, family history of Dupuytren's Disease and associated fibrotic diseases. Then, the patients underwent a clinical examination to identify and characterize the involvement of the fingers. The patients were also assessed in regard to whether they presented Dupuytren's Disease severity factors. Results: 140 patients were included, 70.7% men and 29.3% women. Only 42.3% reported being of European ancestry; 20% had first-degree relatives with the disease; 59.3% presented comorbidities, including hypertension, diabetes, chronic heart disease, dyslipidemia, epilepsy, and HIV infection; 15.8% had Ledderhose disease, 7.1% had Peyronie's disease. 31% were smokers, 16.6% were alcoholic, and 37.1% were phenobarbital users; 40% presented with a severe form of DD. Conclusion: The population studied was composed of Brazilians, most of whom did not report European ancestry; still, they presented several characteristics similar to those described in literature worldwide.
