Background Psoriasis is an inflammatory, immune-mediated skin condition that can provoke various clinical phenotypes and is strongly associated with MASLD (Metabolic dysfunction-Associated Steatotic Liver Disease), a form of fatty liver disease of metabolic origin. The two conditions share numerous risk factors and pathophysiological pathways. Objectives This study aims to investigate the potential role of systemic therapies for psoriasis in improving MAFLD, while also evaluating the relationship between clinical characteristics (duration of disease, severity of psoriasis, BMI) and liver parameters (LSM and CAP) in patients with psoriasis. Materials and methods A retrospective longitudinal study was conducted on adult patients with moderate-to-severe psoriasis and liver involvement. For each patient, demographic, anthropometric and clinical parameters were recorded; a specialist physician performed transient elastography (TE) to assess the degree of fibrosis and hepatic steatosis using a FibroScan, evaluating the LSM (Liver Stiffness Measurement) and CAP (Controlled Attenuation Parameter) parameters. Results The LSM had an average reduction of 0.67 kPa and a median reduction of 0.60 kPa; in percentage terms, the average decreased by 17.29% and the median by 11.68%. As for CAP, we found an average decrease of 30.20 dB/m and a median reduction of 17 dB/m, which, in percentage terms, translates into an average decrease of 31.52% and a median decrease of 5.34%. When categorising the results by patient gender and whether PASI 100 was achieved, no statistically significant results were found. Conclusions The study describes an improvement in liver function in psoriasis patients treated with systemic drugs, supporting the hypothesis that improving chronic inflammation in psoriasis may help reduce fibrosis and hepatic steatosis in psoriatic patients. This opens up new perspectives in the integrated treatment of two highly prevalent conditions, albeit with limitations related to the small sample size and limited follow-up duration. Future studies on larger populations will be necessary to confirm these observations and evaluate the impact of different classes of systemic drugs.
Introduzione La psoriasi è una patologia infiammatoria e immuno-mediata della cute, la quale si manifesta attraverso diversi fenotipi clinici ed è fortemente associata alla MASLD (Metabolic dysfunction-Associated Steatotic Liver Disease), la steatosi epatica di origine metabolica; le due patologie condividono numerosi fattori di rischio e vie fisiopatologiche. Scopo dello studio Questo studio mira a indagare il potenziale ruolo delle terapie sistemiche per la psoriasi nel miglioramento della MAFLD, valutando inoltre la relazione tra le caratteristiche cliniche (durata di malattia, severità della psoriasi, BMI) e i parametri epatici (LSM e CAP) in pazienti affetti da psoriasi. Materiali e metodi È stato condotto uno studio longitudinale retrospettivo su pazienti adulti affetti da psoriasi moderato-severa e coinvolgimento epatico. Per ogni paziente sono stati rilevati i parametri anagrafici, antropometrici e clinici; un medico specializzato ha eseguito l’elastografia transiente epatica (TE) per valutare il grado di fibrosi e steatosi epatica tramite l’uso di un FibroScan valutando i parametri LSM (Liver Stiffness Measurement) e CAP (Controlled Attenuation Parameter). Risultati Il LSM ha avuto una riduzione media di 0,67 kPa e una riduzione mediana di 0,60 kPa; dal punto di vista percentuale, la media è diminuita del 17,29% e la mediana dell’11,68%. Per quanto riguarda il CAP abbiamo rilevato una diminuzione media di 30,20 dB/m e una riduzione mediana di 17 dB/m, che, in termini percentuali, si traduce in un calo della media del 31,52% e della mediana del 5,34%. Categorizzando i risultati per il sesso dei pazienti e per il raggiungimento o meno del PASI 100, non sono stati trovati risultati statisticamente significativi. Discussione e conclusioni Lo studio descrive un miglioramento del quadro epatico nei pazienti affetti da psoriasi trattati con farmaci sistemici, supportando l'ipotesi che il miglioramento dell’infiammazione cronica nella psoriasi possa contribuire a ridurre i valori di fibrosi e steatosi epatica nei pazienti psoriasici. Questo apre nuove prospettive nel trattamento integrato di due condizioni ad elevata prevalenza, pur con i limiti legati alla numerosità ridotta del campione e alla durata limitata del follow-up. Studi futuri su popolazioni più ampie saranno necessari per confermare tali osservazioni e valutare l’impatto delle diverse classi di farmaci sistemici.
