Background: Psoriasis is frequently accompanied by cardiovascular diseases based on the shared immunopathogenic pathway. Authors determined the effect of interleukin (IL)-17 inhibitor therapy on arterial intima-media thickness (IMT) among severe psoriatic patients. Methods: Thirty-one severe psoriatic patients were enrolled. Twenty received secukinumab and 11 received ixekizumab. Before treatment initiation and after 6 months, the carotid-brachial-femoral IMT, the Psoriasis Area Severity Index (PASI), the Dermatology Life Quality of Index (DLQI) and the EuroQol Visual Analogue Scale (EQ VAS) were evaluated. Results: After 6 months, significant ameliorations were observed in PASI (p < 0.001) from 18 to 0, in DLQI (p < 0.001) from 17 to 0, in EQ VAS (p < 0.001) from 60 to 90, in right carotid IMT (p < 0.001) from 1.1 mm to 0.8 mm, in left carotid IMT (p < 0.001) from 1.1 mm to 0.7 mm, in right brachial IMT (p < 0.001) from 0.75 mm to 0.6 mm, in left brachial IMT (p < 0.001) from 0.8 mm to 0.5 mm, in right femoral IMT (p < 0.001) from 0.9 mm to 0.7 mm and in left femoral IMT (p < 0.001) from 0.8 mm to 0.7 mm. Conclusions: By reducing the inflammation of the vascular wall, anti-IL-17 therapy may have a beneficial long-term effect on cardiovascular complications of systemic inflammation.

BACKGROUND: Psoriasis is frequently accompanied by metabolic syndrome. Effect of anti-tumor necrosis factor therapies on increases in body weight is well-known. Data on the effects of interleukin-17 inhibitors are limited. Authors determined the effect of anti-interleukin-17 therapies on the body composition and serum lipid and inflammatory parameters among severe psoriatic patients. METHODS: Thirty-five severe psoriatic patients were enrolled. Twenty-two received secukinumab and 13 received ixekizumab as their 2nd-or 3rd-line biological treatment. Before treatment initiation and 6 months later, laboratory examinations measuring metabolic and inflammatory panels and body composition analyses were performed. RESULTS: After 6 months, a significant reduction was observed in psoriasis area severity index (p < 0.001) from 18 to 0, in c-reactive protein (p < 0.001) from 6.6 to 4.00 mg/L, in low-density lipoprotein-cholesterol (p = 0.004) from 3.69 to 3.19 mmol/L, and an improvement in high-density lipoprotein-cholesterol (p = 0.022) from 1.31 to 1.40 mmol/L. Median baseline body mass index was 32.80 kg/m2. The body composition parameters did not show any significant changes. CONCLUSIONS: Anti-interleukin-17 therapy of severe psoriatic patients does not cause significant changes in body composition parameters. Improvements in the lipid and inflammatory parameters might have a beneficial effect on patients’ cardiometabolic status. This effect might be detectable in high-risk obese psoriatic patients.

Psoriasis mainly affects the skin and joints and has serious impacts on the physical, emotional, and financial life of patients. Recent studies have demonstrated that other comorbidities are frequently detected in psoriatic patients. A strong association with the development of cardiovascular diseases, such as hypertension, myocardial infarction, and stroke is responsible for the shortened (by 4.5‐5 years) life expectancy of severe psoriatic patients. Systemic inflammation plays an important role in the interrelationship between psoriasis and atherosclerotic plaque formation, which is a common immunopathogenic pathway that explains the multiorgan involvement in psoriasis. As far life‐threatening cardiovascular diseases are very often symptom‐free, the treating dermatologist's responsibility is to initiate interdisciplinary holistic patient care, which may lead to directly saved patients' lives. Holistic care of severe psoriatic patients should include regular cardiac monitoring using cardiovascular imaging modalities and functional testing to detect even subclinical coronary artery disease. Effective anti‐inflammatory treatment with biologic therapies may have beneficial effects on the cardiovascular state and may reduce the incidence of cardiac events. The authors review the latest findings on the shared immunopathogenic background of psoriasis and cardiovascular diseases and discuss the available data about the cardiovascular responses to the currently used biologic treatments.

It is unclear whether biological antipsoriatic therapies affect seroconversion after messenger ribonucleic acid (mRNA)‐based antisevere acute respiratory syndrome coronavirus 2 (anti‐SARS‐CoV‐2) vaccinations. To assess antibody formation and the incidence of side effects after anti‐SARS‐CoV‐2 mRNA vaccinations in psoriatic patients receiving different biologicals compared to healthy controls. 102 moderate‐to‐severe psoriatic patients (56.2 [±13.5] years) and 55 age‐matched healthy (56.4 ± 13.6 years) volunteers were included in our study. Ten to 21 days after the administration of the second dosage of BNT162b2 or mRNA‐1273 vaccine, antibody levels specific to the SARS‐CoV‐2 spike (S) protein receptor binding domain were monitored. The incidence of postvaccination side effects was recorded and compared to real‐life data in the literature. Of the 102 patients, 57 (55.88%) received tumor necrosis factor (TNF), 28 (27.45%) received interleukin (IL)‐12/23, 16 (15.68%) received IL‐17, and 1 (0.99%) received IL‐23 inhibitors. No significant differences in the median serum level of anti‐SARS‐CoV‐2S antibody were observed between the study population and the control group (median IQR range: 1681.0 U/mL (600.0–4844.0) versus 1984.0 U/mL (1000.0–3136.0; p = 0.82). The most frequent side effects of the mRNA vaccines within 7 days after the administration of both dosages were arm pain on the side of injection (23.53% and 23.53%), fatigue (9.80% and 13.72%), headache (4.9% and 5.88%), and chills or shivering (4.9% and 8.82%). Detectable antibodies against SARS‐CoV‐2S protein appear 10–21 days after the administration of the second dosage of BNT162b2 or mRNA‐1273 vaccines in moderate‐to‐severe psoriatic patients receiving biologicals, similar to those of healthy controls.
