Introduction: Psoriasis is a systemic inflammatory disease that not only involves the skin (1,2) but can be accompanied by PsA in 30% of patients (3) or by peripheral musculoskeletal manifestations in 10 to 60% of individuals with psoriasis that do not meet the diagnostic criteria for PsA (4,5). Objetive: To determine the association between demographic, clinicaland laboratory factors and the involvement of DPTH in plain radiography in patients with psoriasis. Methods: A retrospective cross-sectional and concordance study was carried out. Radiographs of the hands of patients from the database of the population selected in the study by Varela et al (20) were studied. The presence of erosions, resorption, sclerosis and proliferation of the DPTH was looked for. An independent descriptive analysis was performed for groups with psoriatic arthritis, enthesitis, and nail involvement. Results: DPTH changes in patients with psoriasis are frequent, 93% of the subjects had at least one alteration, mainly erosions (75% - 84%). No significant association was found between erosions and nail involvement. The prevalence of erosions was higher in subjects “without PAs” (89%) with a p-value of 0.042 in favor of this group. 84% of the subjects “without enthesitis” and only 50% of the subjects “with enthesitis” presented erosions. Between 59 and 81.8% of the subjects with PsA presented resorption of the DPTH. Conclusion: Radiographic changes in DPTH are common in patients with psoriasis and do not appear to be related to the severity or duration of the disease.
