The aim of this study is to characterize the so-called early arthritis (PsA), because of no clear symptoms of arthritis, in patients otherwise affected by cutaneous psoriasis (PsO), with some of them simultaneous involvement of difficult to treat areas such as nail, scalp and folds (inverse psoriasis). We enrolled 100 patients with suspected early-PsA, 50 was treated with Certolizumab pegol and 50 with Apremilast. Certolizumab pegol (CZP) is an anti-tumor necrosis factor-alpha agent that differs structurally from other biologics because it is a humanized PEG-ylated antibody Fab’ fragment, lacking the IgG1 Fc portion. To date, the CZP is authorized for the treatment of PsO, PsA beyond that rheumatoid arthritis, axial spondyloarthritis/ankylosing spondylitis and Crohn’s disease. Apremilast (APR) is an oral small molecule inhibitor of PDE4 which has been shown to be effective and well tolerated in PsO, PsA and Behçet's disease (phase II). Targeted inhibition of PDE4 results in partial inhibition of pro-inflammatory mediator production, such as TNF-α, interferon-γ, and IL-23, and increases in anti-inflammatory mediator production, such as IL-10, which in turn results in reduced infiltration of immune cells and changes in resident cells of the skin and joints. All patients was evaluated for PASI score, and DAS-44 at BL, W12, W16 ,W24, and W52, respectively for cutaneous and articular involvement. We tested HLA-C06 for Certolizumab and C07 allele for Apremilast in the peripheral blood at baseline as marker of PsO and PsA in both groups and the results were correlated with the PASI score every time. Serum cytokines levels IL17, IL6, IL10, known to be part of the pathogenesis, were performed every time in both groups and correlated with PASI score. Immunohistochemistry was performed to understand the modification during the treatment in the dermis and epidermis layers (K16,CD3,CD8,CD11,Dc-LAMP), skin biopsies were performed only for patients that have given consent to the biopsy . PET/CT analisys was med by fludeoxyglucose uptake (FDG) at Baseline and W52 to detect early arthistis and to evaluate the response to the treatment after the captation of FDG in the skin. We analyzed also genetic polymorphisms located on collagen genes that could be involved in the etiopathogenesis and progression from PsO to PsA. Collagens provide stability and resilience to extracellular matrix of connective tissues, including dermis, blood vessels and bone. Collagen genes could be therefore involved in the etiopathogenesis of Pso and PsA, which are characterized by a dysfunction and instability of the connective tissues. COL10A1 (rs3812111, A/T), COL6A5 (rs12488457, A/C), COL8A1 (rs13081855, G/T) and the miR-146a (rs2910164, G/C) were selected as potential biomarkers for PsO and PsA susceptibility. Our results showed reduction every time of the clinical (PASI, DAS-44, DLQI) and serological biomarkers (evaluation of serum cytokines levels) in both groups of patients, detection at the baseline of early arthritis by PET/CT and correlation between PASI score and C06-C07 detection as good responders patients.
Lo scopo di questo lavoro è quello di caratterizzare la cosiddetta artrite precoce (PsA), in assenza di sintomi clinici tipici dell’ artrite, in pazienti affetti da psoriasi cutanea (PsO), con coinvolgimento simultaneo delle aree difficili da trattare come: unghie, cuoio capelluto e pieghe (psoriasi inversa). Abbiamo arruolato 100 pazienti con sospetta PsA precoce, 50 trattati con Certolizumab pegol e 50 con Apremilast. Certolizumab pegol (CZP) è un farmaco anti-Tnf alfa che differisce strutturalmente da altri biologici perché è un frammento Fab' di anticorpo PEG-ilato umanizzato, privo della porzione IgG1 Fc. Ad oggi, CZP è autorizzato per il trattamento della PsO, PsA oltre che dell’artrite reumatoide, spondiloartrite assiale, spondilite anchilosante e morbo di Crohn. Apremilast (APR) è un inibitore orale della PDE4 che ha dimostrato essere efficace e ben tollerato nei pazienti affetti da PsO, PsA e malattia di Behçet (attualmente in fase II). L'inibizione mirata della PDE4 si traduce in una parziale inibizione della produzione di mediatori proinfiammatori, come TNF-α, interferone-γ e IL 23, questo aumenta la produzione di mediatori antinfiammatori, come IL-10, che a sua volta si traduce in una ridotta infiltrazione delle cellule immunitarie e con cambiamenti nelle cellule infiammatorie localizzate a livello cutaneo ed articolare. Tutti i pazienti sono stati valutati attraverso alcuni paramentri clinici come il PASI ed il DAS-44 al BL, W12, W16, W24 e W52, rispettivamente per il coinvolgimento cutaneo e articolare. Abbiamo testato HLA-C06 per Certolizumab e l'allele C07 per Apremilast nel sangue periferico dei pazienti, al basale, come marker di PsO e PsA in entrambi i gruppi ed i risultati sono stati correlati con il valore del PASI. Inoltre abbiamo eseguito il dosaggio dei livelli di citochine sieriche come IL17, IL6, IL10, noti per essere parte importante nella patogenesi della patologia, queste citochine sono state dosate in entrambi i gruppi di pazienti e correlati al punteggio PASI. Per capire l’efficacaia dei due farmaci e le modifiche a livello istologico abbiamo esguito l'immunoistochimica con diversi anticorpi (K16, CD3, CD8, CD11, Dc-LAMP), su biopsie cutanee, eseguite solo per i pazienti che hanno dato il consenso alla biopsia. Da un punto di vista strumentale abbiamo eseguito un esame PET / TC per la ricerca dell’artrite in fase precoce e per valutare la risposta al trattamento anche a livello cutaneo attraverso l’assorbimento del fluorodeossiglucosio un radiofarmaco che si lega ai tessuti infammati (FDG) sia al basale che dopo 52 settimane di trattamento. Abbiamo analizzato inoltre anche i polimorfismi genetici localizzati sui geni del collagene che potrebbero essere coinvolti nell'eziopatogenesi e nella progressione da PsO a PsA. Il collagene fornisce infatti stabilità e resistenza alla matrice extracellulare dei tessuti connettivi, inclusi derma, vasi sanguigni e ossa. I geni del collagene potrebbero quindi essere coinvolti nell'eziopatogenesi della psoriasi e dell'artrite psoriasica, che sono caratterizzati da una disfunzione ed instabilità dei tessuti connettivi. COL10A1 (rs3812111, A / T), COL6A5 (rs12488457, A / C), COL8A1 (rs13081855, G / T) e miR-146a (rs2910164, G / C) sono stati selezionati come potenziali biomarcatori per la suscettibilità di PsO e PsA. I nostri risultati hanno mostrato una riduzione a tutti i tempi dei biomarcatori clinici (PASI, DAS-44, DLQI) e sierologici (valutazione dei livelli di citochine sieriche) in entrambi i gruppi di pazienti, inoltre abbiamo dimostrato attraverso l’esame PET / TC la presenza di una forma di “early artrhitis” grazie alla captazione del FDG nei tessuti articolari infiammati ed abbiamo correlato i nostri dati al PASI ed alla presenza o meno dell’allele C06 o C07 riconoscendo i pazienti in due gruppi: responders e non responders alla terapia biologica.

Abstract
The aim of this study is to characterize the so-called early arthritis (PsA), because of no clear symptoms of arthritis, in patients otherwise affected by cutaneous psoriasis (PsO), with some of them simultaneous involvement of difficult to treat areas such as nail, scalp and folds (inverse psoriasis). We enrolled 100 patients with suspected early-PsA, 50 was treated with Certolizumab pegol and 50 with Apremilast. Certolizumab pegol (CZP) is an anti-tumor necrosis factor-alpha agent that differs structurally from other biologics because it is a humanized PEG-ylated antibody Fab’ fragment, lacking the IgG1 Fc portion. To date, the CZP is authorized for the treatment of PsO, PsA beyond that rheumatoid arthritis, axial spondyloarthritis/ankylosing spondylitis and Crohn’s disease. Apremilast (APR) is an oral small molecule inhibitor of PDE4 which has been shown to be effective and well tolerated in PsO, PsA and Behçet's disease (phase II).
