Background: Up to 30% of Psoriasis (PsO) patients are prone to develop Psoriatic Arthritis (PsA). Agreement on how to identify PsO patients at risk of developing PsA is still lacking (1).
Objectives: To identify predictors of PsA development in PsO patients through a systematic literature review (SLR) and meta-analyses (MA).
Methods: MEDLINE, EMBASE and COCHRANE databases were searched (up to February 22nd, 2020). The PICO framework (population = PsO patients; intervention = clinical, environmental, imaging and genetic features; comparator = not applicable; outcome = PsA development) was used to design searches and define the eligibility of studies for inclusion. The MA focuses on 3 major features as possible predictors: i) PsO skin and nail involvement; ii) musculoskeletal (MSK) complaints; iii) inflammation and structural damage detected by imaging (
Results: 4698 articles were screened for eligibility, 110 underwent a full reading and 29 were finally included.
Studies reporting the major features as possible predictors of PsA development.

| Simon D, 2020 | Arthralgia | RR: 2.04 [0.86; 4.86] | 2.4±1.5 ys |
| Sub-clinical inflammation or structural damage detected by imaging | Variables | Incident-PsA cases | Follow-up |
| Faustini, 2015 | MRI | RR: 2.10 [0.75; 5.90] | 1.2±0.2 ys |
| Elnady, 2019 | MSK-US | RR: 5.38 [1.17; 24.63] | 2 ys |
| Zabotti, 2019 | MSK-US | RR: 6.86 [0.83; 56.63] | 1.6±0.5 ys |
| Simon D, 2020 | HR-pQCT | RR: 4.32 [1.96; 9.55] | 2.3±1.4 ys |
Conclusion: Arthralgia and inflammation and/or structural damage detected by imaging are predictive features, likely prodromal, of PsA development. PsO severity and nail pitting are clinical manifestations related to PsA development.
