Background.Psoriasis is a chronic inflammatory skin disease with a multifactorial etiology, affecting 2–3% of the global population. According to the "psoriatic march" or "inflammatory skin march" model, the spread of inflammation from the skin to the systemic circulation in psoriatic patients may trigger immune-mediated systemic alterations, potentially leading to significant comorbidities, including coronary microcirculatory dysfunction. A reduction in coronary flow reserve (CFR) in psoriasis patients with normal epicardial arteries may suggest the presence of coronary microvascular dysfunction (CMD).Objective This study aims to assess how the coronary microcirculation responds to pharmacological treatment in a cohort of patients with severe psoriasis by monitoring the progression of their clinical condition and CFR variations as an indicator of coronary microvascular function. Furthermore, we investigated potential associations between CFR changes and various demographic, clinical, and with the type of treatment employed, with the goal of further elucidating the mechanisms linking psoriasis, systemic inflammation, and coronary microcirculation.Materials and Methods A prospective study was conducted on a cohort of 540 patients with severe psoriasis, in whom the absence of coronary artery disease was confirmed based on medical history, physical examination, and electrocardiography. All subjects underwent transthoracic echocardiography at baseline and after intravenous adenosine infusion to measure CFR. A total of 411 patients had at least two CFR measurements. The following demographic and clinical variables were considered: sex, age, PASI score, psoriasis duration, psoriatic arthritis, BMI, hypertension, smoking status, total cholesterol, triglycerides, and dyslipidemia. Univariate analyses were performed to investigate associations between clinical and demographic variables and CFR changes. ANOVA was used to compare the effects of different drug classes. Finally, variables associated with ΔCFR were included in a multivariate linear regression model to determine their correlation with the dependent variable while accounting for potential confounding factors.Results The results of our study indicate that pharmacological treatment led to an improvement in the clinical condition, considering both ΔCFR and PASI index variation. The drugs used and their respective effects were: anti-TNF (ΔCFR =0,43±0,81, PASI%=75,66); methotrexate (ΔCFR=0,23±0,59, PASI%=65,02%); cyclosporine (ΔCFR= 0,67 ± 0,85, PASI%= 69,11%); acitretin (ΔCFR= 0,45 ± 0,65, PASI%= 59,06%); topical treatments (ΔCFR=0,29 ± 0,74, PASI%= 51,18%); anti-IL23 (ΔCFR= 0,61 ± 0,75, PASI%= 72,07%); anti-IL17 (ΔCFR= 0,37 ± 0,62, PASI%= 67,63%); otezla (ΔCFR= 0,22 ± 0,61, PASI%= 66,51%). ANOVA revealed a significant difference among these drug classes in both the mean CFR variation (F = 2.26, p = 0.029) and the percentage improvement in the PASI score (F = 2.40, p = 0.020). Multivariate linear regression analysis identified a statistically significant association with age (p < 0.001), sex (p = 0.003), and PASI75 (p = 0.011). Female sex was associated with a lower CFR variation compared to males (0.23 ± 0.67 vs. 0.53 ± 0.75). Additionally, CFR variation decreased with increasing age. Achieving PASI75 had a direct effect on the dependent variable (ΔCFR), regardless of the pharmacological treatment used.Conclusions Based on these findings, achieving a significant improvement in skin inflammation (PASI75) could be considered an indicator of the recovery of coronary microvascular function in patients with psoriasis. This could have a substantial impact on the management of cardiovascular comorbidities in these patients.
Presupposti.La psoriasi è una patologia infiammatoria cronica cutanea ad eziologia multifattoriale,con una prevalenza globale pari al 2-3%.Secondo il modello “psoriatic march” o “inflammatory skin march”,l'espansione dell'infiammazione dalla cute al circolo sistemico nei pazienti affetti da psoriasi potrebbe causare l'insorgenza di alterazioni immuno-mediate sistemiche,portando successivamente a comorbidità importanti,tra cui alterazioni del microcircolo coronarico.Una riduzione della riserva di flusso coronarico (CFR) in pazienti con psoriasi e arterie epicardiche normali può suggerire una disfunzione microvascolare coronarica (CMD).Scopo dello studio.Lo scopo di questo studio è valutare come il microcircolo coronarico risponde al trattamento farmacologico,in una coorte di pazienti affetti da psoriasi di grado severo, monitorando l’andamento della loro condizione clinica e le variazioni della CFR come indicatore della funzionalità microvascolare coronarica.Inoltre,abbiamo indagato le possibili associazioni della variazione della CFR con alcune variabili demografiche,cliniche e con il tipo di trattamento utilizzato,con l’obiettivo di approfondire le dinamiche che regolano la relazione tra psoriasi,infiammazione sistemica e microcircolazione coronarica.Materiali e metodi.È stato condotto uno studio prospettico su una coorte di 540 pazienti affetti da psoriasi grave,in cui l’assenza di malattia coronarica è stata determinata tramite la storia clinica,l’esame obiettivo ed elettrocardiogramma.I soggetti sono stati sottoposti ad un’ecocardiografia transtoracica in condizioni basali e dopo infusione endovenosa di adenosina per ottenere il valore di CFR.411 pazienti hanno effettuato almeno due misurazioni della CFR.Sono state prese in considerazione le seguenti variabili cliniche e demografiche: sesso,età,PASI,durata della psoriasi,artrite psoriasica,BMI,ipertensione arteriosa,fumo,colesterolo totale,trigliceridi, dislipidemia.Sono state condotte analisi univariate per indagare l’associazione tra variabili cliniche e demografiche con la variazione della CFR. Per il confronto tra più tipi di farmaci abbiamo applicato l’ANOVA. Infine, le variabili che hanno mostrato un'associazione con il ΔCFR sono state incluse in un modello di regressione lineare multivariata, al fine di determinare la loro correlazione con la variabile dipendente tenendo conto dei potenziali fattori confondenti.Risultati.I risultati del nostro studio hanno evidenziato che il trattamento farmacologico ha determinato un miglioramento del quadro clinico,considerando sia il ΔCFR sia la variazione dell’indice PASI. I farmaci utilizzati sono stati: anti-TNF (ΔCFR =0,43±0,81, PASI%=75,66); metotrexato (ΔCFR=0,23±0,59, PASI%=65,02%);ciclosporina (ΔCFR= 0,67 ± 0,85, PASI%= 69,11%); acitretina (ΔCFR= 0,45 ± 0,65, PASI%= 59,06%);topici (ΔCFR=0,29 ± 0,74, PASI%= 51,18%); anti-IL23 (ΔCFR= 0,61 ± 0,75, PASI%= 72,07%); anti-IL17 (ΔCFR= 0,37 ± 0,62, PASI%= 67,63%); otezla (ΔCFR= 0,22 ± 0,61, PASI%= 66,51%). L’ANOVA ha mostrato una differenza significativa tra queste classi di farmaci sia nella variazione media della CFR (F=2,26, p=0,029) sia nella variazione del PASI%(F=2,40, p=0,020).L’analisi multivariata con regressione lineare ha mostrato un’associazione statisticamente significativa solo con l’età (p<0,001),il sesso (p=0,003) e il PASI75 (p=0,011).Il sesso femminile è risultato associato a una variazione di CFR inferiore rispetto agli uomini(0,23 ± 0,67 vs 0,53 ± 0,75). All’aumentare dell’età, la variazione della CFR risulta diminuire.Raggiungere il PAI75 ha mostrato un effetto diretto sul ΔCFR indipendentemente dal trattamento farmacologico utilizzato.Conclusioni Alla luce di questi risultati,il raggiungimento di un miglioramento significativo dell’infiammazione cutanea (PASI75) potrebbe essere considerato un indicatore di recupero della funzionalità del microcircolo coronarico nei pazienti con psoriasi.
