E.5 End points |
E.5.1 | Primary end point(s) |
In part 1 of this study we test the hypothesis that nail disease is a specific feature of patients with psoriatic arthritis as compared to other chronic joint diseases. The primary endpoint here is the prevalence and nature including the vascular status in the nailbed and its relationship with DIP arthritis in a real-life cohort of PsA patients.
In part 2 we test the hypothesis that infliximab treatment will have a beneficial effect on the severity of nail disease in a selected cohort of patients with polyarticular psoriatic arthritis and concomitant nail disease. The primary endpoint will be a change in the modified NAPSI score.

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
part 1 cross-sectional part 2 week 26 compared to baseline |
|
E.5.2 | Secondary end point(s) |
In part 1 of the study, secondary endpoint will be the relationship between modified NAPSI scores and DIP arthritis, disease activity as measured by the tender and swollen joint score, CRP, radiographic PARS score, capillaroscopy measurements, hand function (grip strength) and disease duration. The correlations between different disease activity scores and NAPSI scores will be estimated for each of the 5. In part 2 of the study, the key secondary endpoint will be the change in modified NAPSI scores between Week 52 and baseline. Other secondary endpoints will be changes in tender and swollen joint count, HAQ questionnaire, hand function (grip strength), changes in capillaroscopy measurements at Week 26 and at Week 52 from baseline.
