Cardiovascular comorbidity in psoriasis - psoriatic inflammation is more than just skin deep

Improving Cardiovascular Outcomes in the Psoriasis Cohort. Psoriasis and Cardiovascular Disease-Clinician Knowledge, Practice and Perceptions

BACKGROUND

Psoriasis is a risk factor for cardiovascular disease (CVD). This risk is independent and incremental to traditional cardiovascular (CV) risk factors, but clinician and patient perspectives on this risk are unclear. This study aims to assess the knowledge, perceptions, and practice of clinicians and patients with respect to psoriasis and CVD.

METHODS

This cross-sectional study consisted of a self-administered questionnaire capturing demographic characteristics, knowledge of the association between psoriasis and CVD, and perspectives on CV screening and management. This was distributed to members of relevant Australasian Speciality Medical Colleges, speciality societies, and psoriasis patients in public and private clinic settings. Survey data were assessed using descriptive statistics. Logistic regression was used to investigate the relationship between categorical variables and the outcome variable, for example, to determine factors predictive of clinician knowledge and perceptions. For all analyses, a p-value of less than 0.05 was considered statistically significant.

RESULTS

A total of 298 clinicians (dermatologists (86), rheumatologists (56), cardiologists (53), general practitioners (103)) and 102 patients with psoriasis were surveyed. Regarding clinician knowledge of the association between psoriasis and CVD, dermatologists and rheumatologists indicated knowledge of this association (98.8%) (85/96) and 91.1% (51/56) respectively, while only 54.7% (29/53) of cardiologists and 29.1% (30/103) of GPs indicated knowledge of this association. Only 23.5% (24/102) of patients surveyed indicated knowledge of this association. Clinicians with a higher proportion of their caseload including psoriasis patients were significantly more likely to be aware of the association between psoriasis and CVD (OR 3.05 [1.64, 5.68]; p < 0.001). Most clinicians nominated GPs as best placed to facilitate CV risk factor screening and management (dermatologists 80.2% (69/86); rheumatologists 83.9% (47/56); cardiologists 75.5% (40/53); GPs 88.3% (91/103)). Patients preferred specialist input and multidisciplinary care for CVD risk management; 34.3% (35/102) nominated a cardiologist as the preferred clinician, and 23.5% (24/102) indicated preference for a multidisciplinary team.

LIMITATIONS

The possibility of sampling and response bias, inherent in the study design, is acknowledged; however, responses are likely representative of clinician and patient sentiments on this issue and in keeping with similar study findings.

CONCLUSION

Clinician and patient knowledge of the relationship between psoriasis and CVD needs to be improved. The establishment of a national consensus approach to address this gap in clinical care is needed.

Inflammation and olfactory loss are associated with at least 139 medical conditions

Olfactory loss accompanies at least 139 neurological, somatic, and congenital/hereditary conditions. This observation leads to the question of whether these associations are correlations or whether they are ever causal. Temporal precedence and prospective predictive power suggest that olfactory loss is causally implicated in many medical conditions. The causal relationship between olfaction with memory dysfunction deserves particular attention because this sensory system has the only direct projection to memory centers. Mechanisms that may underlie the connections between medical conditions and olfactory loss include inflammation as well as neuroanatomical and environmental factors, and all 139 of the medical conditions listed here are also associated with inflammation. Olfactory enrichment shows efficacy for both prevention and treatment, potentially mediated by decreasing inflammation.

Association between aortic calcification and cytokine levels in patients with peripheral artery disease

Aortic calcification-a marker of advanced atherosclerosis in large arteries-associates with cardiovascular mortality and morbidity. Little is known about the soluble inflamJarmatory profiles involved in large artery atherosclerosis. We investigated the correlation between aortic calcification in the abdominal aorta and cytokine levels in a cohort of peripheral artery disease patients. Aortic calcification index was measured from computed tomography exams and circulating cytokine levels were analyzed from blood serum samples of 156 consecutive patients prior to invasive treatment of peripheral artery disease. The study included 156 patients (mean age 70.7 years, 64 (41.0%) women). The mean ankle-brachial index (ABI) was 0.64 and the mean aortic calcification index (ACI) was 52.3. ACI was associated with cytokines cutaneous T-cell-attracting chemokine CTACK (β 23.08, SE 5.22, p < 0.001) and monokine induced by gamma-interferon MIG (β 9.40, SE 2.82, p 0.001) in univariate linear regression. After adjustment with cardiovascular risk factors, CTACK and MIG were independently associated with ACI, β 17.9 (SE 5.22, p < 0.001) for CTACK and β 6.80 (SE 3.33, p 0.043) for MIG. CTACK was significantly higher in the patients representing the highest ACI tertile (highest vs. middle, 7.53 vs. 7.34 Tukeys HSD p-value 0.023 and highest vs. lowest tertile 7.53 vs. 7.29, Tukeys HSD p-value 0.002). MIG was significantly higher in the highest tertile versus lowest (7.65 vs. 7.30, Tukeys HSD p-value 0.027). Cytokines CTACK and MIG are associated with higher ACI, suggesting that CTACK and MIG reflect atherosclerotic disease burden of the aorta. This might further suggest the possible association with other cardiovascular morbidities.

The association of psoriasis with composite dietary antioxidant index and its components: a cross-sectional study from the National Health and Nutrition Examination Survey

BACKGROUND

Psoriasis is a chronic inflammatory skin disorder associated with various comorbidities. The role of nutrition and dietary antioxidants in psoriasis management has gained attention. The Composite Dietary Antioxidant Index (CDAI) quantifies overall dietary antioxidant intake, but its association with psoriasis remains unclear. This study aimed to investigate the association between the CDAI and psoriasis, as well as the relationship between individual components of CDAI and psoriasis risk.

METHODS

Data from the US National Health and Nutrition Examination Survey (NHANES) were analyzed. Baseline characteristics, CDAI scores, and psoriasis status were assessed. Multivariable logistic regression and restricted cubic splines were employed to analyze the association.

RESULTS

The study included 23,311 participants, with 621 diagnosed with psoriasis. Higher CDAI scores were associated with a lower odds ratio (OR) of psoriasis occurrence (OR = 0.72, 95% CI 0.56-0.92, P = 0.009 in Model 3). Vitamin E intake exhibited an inverse correlation with psoriasis risk (OR = 0.76, 95% CI 0.60-0.96, P = 0.039 in Model 3). Other CDAI components did not show significant associations with psoriasis.

CONCLUSION

This study demonstrates a significant inverse association between CDAI and psoriasis, indicating that higher dietary antioxidant intake is associated with a reduced risk of psoriasis. Specifically, higher vitamin E intake was associated with a lower likelihood of psoriasis. These findings underscore the potential role of dietary antioxidants in psoriasis management. Further research is warranted to elucidate the underlying mechanisms and explore targeted dietary interventions.

Alcohol abuse and discretionary habits in psoriatic patients: impact on IL-17 and IL-23 inhibitors response

BACKGROUND

Alcohol abuse is correlated with the onset and worsening of psoriasis, but its effects, as for smoking, on biological therapies are still poorly investigated.

MATERIALS AND METHODS

This study aimed to determine the prevalence of alcohol abuse and other discretionary habits (such as smoking and sedentary lifestyle) in patients with psoriasis treated with topicals, conventional systemic and biologic therapies. The second objective is to investigate the impact of discretionary habits, focusing on alcohol abuse, on the response to biological therapy. To identify alcohol dependence, the CAGE questionnaire was distributed among patients of our clinic.

RESULTS

305 patients were included with 18% at high risk of alcohol abuse. Clinically, guttate psoriasis and psoriatic arthritis were more common in patients at higher risk of alcohol abuse. Furthermore, patients with an alcohol problem who started biological therapy reported a higher PASI than those who drank less. None of the considered variables seemed to correlate with discontinuation of medication or with lower achievement of the analyzed outcomes (PASI100, PASI90, and PASI≤3). There was a stronger association between alcohol dependence and patients receiving conventional therapy than with patients receiving biologics.

CONCLUSIONS

The efficacy of biologicals did not seem to be impacted by alcohol consumption, smoking, or sedentary lifestyle.

Drug survival and clinical effectiveness of secukinumab, ixekizumab, brodalumab, guselkumab, risankizumab, tildrakizumab for psoriasis treatment

BACKGROUND

Biologics targeting IL-23 and IL-17 show efficacy and safety in the treatment of moderate-to-severe psoriasis.

OBJECTIVE

To investigate drug survival in patients with psoriasis treated with biologics.

PATIENTS AND METHODS

We performed a comparative evaluation of the achievement of PASI 90 and PASI ≤ 3 at 16, 28, and 52 weeks along with a DS (drug survival) analysis with IL-17 and IL-23 inhibitors brodalumab, ixekizumab, secukinumab, risankizumab, tildrakizumab, and guselkumab on 1,057 patients.

RESULTS

IL-17 inhibitors showed a faster achievement of PASI 90 and PASI ≤ 3 with significant superiority over IL-23 inhibitors at week 16 (p < 0.001; 56% vs. 42% and 70% vs. 59%, respectively). A difference was shown in favor of IL-23 inhibitors regarding DS (p < 0.001), which was 88% at 24 months vs. 75% for IL-17 inhibitors. In multivariate analysis, IL-23 inhibitors (HR 0.54 CI 0.37-0.78, p = 0.001), and male sex (HR 0.57 CI 0.42-0.76, p < 0.001) were all associated with a lower probability of drug interruption. Risankizumab (HR 0.42 CI 0.26-0.69, p = 0.001), guselkumab (HR 0.49 CI 0.24-0.99, p = 0.046), and male sex (HR 0.57 CI 0.43-0.77, p < 0.001) were associated with a lower probability of drug interruption than secukinumab.

CONCLUSIONS

IL-23 inhibitors showed the best performance on DS. Overall, the most effective class was IL-17 inhibitors considering the short-term effectiveness, but long-term effectiveness is in favor of anti-IL-23.

Drug survival und klinische Wirksamkeit von Secukinumab, Ixekizumab, Brodalumab, Guselkumab, Risankizumab und Tildrakizumab in der Behandlung der Psoriasis: Drug survival and clinical effectiveness of secukinumab, ixekizumab, brodalumab, guselkumab, risankizumab, tildrakizumab for psoriasis treatment

Hintergrund

Biologika, die die Interleukine IL‐23 and IL‐17 hemmen, haben sich in der Behandlung der mittelschweren bis schweren Psoriasis als sicher und wirksam erwiesen.

Studienziel

Medikamenten‐Überleben bei Patienten mit Psoriasis zu untersuchen, die mit Biologika behandelt werden.

Patienten und Methoden

Wir haben die Erreichung des PASI 90 und PASI ≤3 nach 16, 28, and 52 Wochen im Vergleich der IL‐17‐ und IL‐23‐Inhibitoren Brodalumab, Ixekizumab, Secukinumab, Risankizumab, Tildrakizumab und Guselkumab bei insgesamt 1057 Patienten untersucht sowie eine Drug Survival‐Analyse durchgeführt.

Ergebnisse

Unter IL‐17‐Inhibitoren wurden PASI 90 und PASI ≤3 schneller erreicht; nach 16 Wochen waren sie den IL‐23‐Inhibitoren signifikant überlegen (p <0,001; 56% vs. 42% beziehungsweise 70% vs. 59%). Im Drug Survival zeigte sich allerdings ein Vorteil für die IL‐23‐Inhibitoren; dieses betrug nach 24 Monaten 88% im Gegensatz zu 75% für die IL‐17‐Inhibitoren (p <0,001). In der multivariaten Analyse waren die IL‐23‐Inhibitoren (HR 0,54 CI 0,37–0,78, p =  0,001) sowie männliches Geschlecht (HR 0,57 CI 0,42–0,76, p <0,001) mit einer geringeren Wahrscheinlichkeit des Absetzens der Medikation assoziiert. Risankizumab (HR 0,42 CI 0,26‐0,69, p =  0,001), Guselkumab (HR 0,49 CI 0,24–0,99, p =  0,046) und männliches Geschlecht (HR 0,57 CI 0,43–0,77, p <0,001) waren mit geringerer Wahrscheinlichkeit des Absetzens der Medikation assoziiert als Secukinumab.

Schlussfolgerung

IL‐23‐Inhibitoren zeigten bezüglich des Drug Survival die besten Ergebnisse. Auf kürzere Sicht waren die IL‐17‐Inhibitoren wirksamer, aber die Langzeitergebnisse sprechen eher für die IL‐23‐Inhibitoren.

Entwicklung der Patientencharakteristika und der Wirksamkeit der Biologika-Therapie bei Patienten des Österreichischen Psoriasis-Registers von 2004 bis 2022

Hintergrund und Ziele

In dieser Studie wurde untersucht, inwieweit die Einführung wirksamerer Medikamente in jüngster Zeit zu einer Verbesserung der Behandlungsergebnisse von Psoriasis‐Patienten im klinischen Alltag geführt hat.

Patienten und Methodik

Es wurden Patientencharakteristika und die Wirksamkeit der Therapie im ersten Behandlungsjahr bei Biologika‐naiven Patienten von 2004 bis heute analysiert, unabhängig von Therapiewechseln.

Ergebnisse

Die Daten von 2729 Patienten eigneten sich für die Analyse. Der Anteil der weiblichen Patienten stieg über die Jahre signifikant von 29,9% auf 36,2% (p < 0,028), während der Anteil der Patienten mit einer Psoriasis‐Arthritis von 36,6% auf 30,0% sank (p < 0,001). Außerdem nahm die Dauer der Psoriasis‐Erkrankung und der PASI‐Wert zu Beginn der Behandlung in Verlauf der Zeit signifikant ab. Die „letzte Beobachtung übernommen“ (LOCF)‐Analyse zeigte, dass das PASI‐90‐Ansprechen drei Monate nach Therapiebeginn von 18,9% auf 44,6% und 12 Monate nach Therapiebeginn von 32,9% auf 66,8% anstieg. Ebenso stiegen die PASI<3 Befunde von 33,2% auf 66,0% 3 Monate und von 41,9% auf 78,9% 12 Monate nach Behandlungsbeginn.

Schlussfolgerungen

Die kontinuierliche Einführung wirksamerer Biologika hat zu einer deutlichen Verbesserung des klinischen Ansprechens und der Patientenversorgung geführt. Dennoch erreicht auch heute noch, je nach gewähltem Endpunkt, jeder dritte bis fünfte Patient kein vollständig zufriedenstellendes Behandlungsergebnis (d.h. PASI 90 oder PASI ≤ 3).

Evolution of characteristics and biologic treatment effectiveness in patients of the Austrian psoriasis registry from 2004-2022

BACKGROUND AND OBJECTIVES

This study analyzed the extent to which the recent introduction of more effective treatments has led to an improvement in real-world psoriasis patients.

PATIENTS AND METHODS

Patient characteristics and the first-year treatment effectiveness in biologic-naive patients have been analyzed since 2004 until now, irrespective of treatment switches.

RESULTS

Data from 2,729 patients were eligible for this analysis. The proportion of female patients increased significantly over the years from 29.9% to 36.2% (p < 0.028), while the number of patients with psoriatic arthritis declined from 36.6% to 30.0% (p < 0.001). Moreover, the duration of psoriatic disease and PASI at the start of the treatment significantly decreased. Last observation carrief forward (LOCF) analysis indicated that PASI 90 response increased from 18.9 to 44.6% at 3 months and from 32.9 to 66.8% at 12 months after treatment started. Similary, the PASI ≤ 3 rates increased from 33.2% to 66.0% at 3 months and from 41.9% to 78.9% at 12 months after the treatment started.

CONCLUSIONS

The continuous introduction of more efficient biologics has led to significant improvements in patient care and clinical outcomes. Though one out of three to five patients, depending on the endpoint selected, nowadays still does not achieve an entirely satisfactory treatment response (i.e., PASI 90 or PASI ≤ 3).

Molecular consideration relevant to the mechanism of the comorbidity between psoriasis and systemic lupus erythematosus (Review)

Systemic lupus erythematosus (SLE), a common autoimmune disease with a global incidence and newly diagnosed population estimated at 5.14 (range, 1.4-15.13) per 100,000 person-years and 0.40 million people annually, respectively, affects multiple tissues and organs; for example, skin, blood system, heart and kidneys. Accumulating data has also demonstrated that psoriasis (PS) can be a systemic inflammatory disease, which can affect organs other than the skin and occur alongside other autoimmune diseases, such as inflammatory bowel disease, multiple sclerosis, rheumatoid arthritis and SLE. The current explanations for the possible comorbidity of PS and SLE include: i) The two diseases share susceptible gene loci; ii) they share a common IL-23/T helper 17 (Th17) axis inflammatory pathway; and iii) the immunopathogenesis of the two conditions is a consequence of the interactions between IL-17 cytokines with effector Th17 cells, T regulatory cells, as well as B cells. In addition, the therapeutic efficacy of IL-17 or TNF-α inhibitors has been demonstrated in PS, and has also become evident in SLE. However, the mechanisms have not been investigated. To the best of our knowledge, there remains a lack of substantial studies on the correlation between PS and SLE. In the present review, the literature, with regards to the epidemiology, genetic predisposition, inflammatory mechanisms and treatment of the patients with both PS and SLE, has been reviewed. Further investigations into the molecular pathogenic mechanism may provide drug targets that could benefit the patients with concomitant PS and SLE.
