Abstract
Psoriasis is associated with a higher risk of liver diseases. We investigated the impact of hepatic steatosis (European cohort) and hepatic inflammation (United States cohort) on subclinical atherosclerosis. In the European cohort (n = 76 psoriasis participants and 76 controls), nonalcoholic fatty liver disease, assessed by the sonographic hepatorenal index, was more prevalent in psoriasis than in controls (61% vs. 45%; P = 0.04). Participants with psoriasis with nonalcoholic fatty liver disease had a higher prevalence of subclinical atherosclerosis (ultrasonographic presence of plaque in femoral or carotid arteries) than participants with psoriasis without nonalcoholic fatty liver disease (61% vs. 23%; P = 0.006) and controls with nonalcoholic fatty liver disease (61% vs. 32%; P < 0.05). Sonographic hepatorenal index was a determinant of subclinical atherosclerosis in psoriasis (OR = 3.5; P = 0.01). In the United States cohort (n = 162 participants with psoriasis who underwent positron emission tomography and coronary computed tomography angiography), those with high hepatic 2-[fluorine-18]fluoro-2-deoxy-D-glucose uptake had higher noncalcified (1.3 [0.49 mm2] vs. 1.0 [0.40 mm2]), fibrofatty (0.23 [0.15 mm2] vs. 0.11 [0.087 mm2]), and lipid-rich necrotic core (4.3 [2.3 mm2] vs. 3.0 [1.7 mm2]) coronary burden (all P < 0.001). Hepatic 2-[fluorine-18]fluoro-2-deoxy-D-glucose uptake associated with noncalcified (β = 0.28; P < 0.001), fibrofatty (β = 0.49; P < 0.001), and lipid-rich necrotic core (β = 0.28; P = 0.003) burden. These results show the downstream cardiovascular effects of subclinical liver disease in psoriasis.

Abstract
Vegans and vegetarians often consume foods containing photosensitizers capable of triggering phytophotodermatitis. The potential effect of vegan and vegetarian diets on the response of psoriatic patients undergoing phototherapy is not well characterized. We assessed clinical outcomes of vegan, vegetarian and omnivore adult psoriatic patients undergoing band ultraviolet B phototherapy (NB-UVB). In this multicenter prospective observational study, we enrolled 119 adult, psoriatic patients, of whom 40 were omnivores, 41 were vegetarians and 38 were vegans, with phototherapy indication. After determining the minimum erythemal dose (MED), we performed NB-UVB sessions for 8 weeks. The first irradiation dosage was 70.00% of the MED, then increased by 20.00% (no erythema) or by 10.00% (presence of erythema) until a maximum single dose of 3 J/cm2 was reached and constantly maintained. All the enrolled patients completed the 8 weeks of therapy. Severe erythema was present in 16 (42.11%) vegans, 7 (17.07%) vegetarians and 4 (10.00%) omnivores (p < 0.01). MED was lowest among vegans (21.18 ± 4.85 J/m2), followed by vegetarians (28.90 ± 6.66 J/m2) and omnivores (33.63 ± 4.53 J/m2, p < 0.01). Patients with severe erythema were more likely to have a high furocumarin intake (OR 5.67, 95% CI 3.74-8.61, p < 0.01). Vegans consumed the highest amount of furocumarin-rich foods. A model examining erythema, adjusted for gender, age, skin type, MED, phototherapy type, number of phototherapies and furocumarin intake, confirmed that vegans had a lower number of treatments. Vegans had more frequent severe erythema from NB-UVB, even after adjustment of the phototherapy protocol for their lower MED. Assessing diet information and adapting the protocol for vegan patients may be prudent.

Abstract
BACKGROUND Topical agents are still the mainstay for the treatment of mild-to-moderate plaque psoriasis, in which fixed combinations play an important role. Tazarotene/betamethasone dipropionate (Taz/BD) cream is a novel fixed combination approved for treating plaque psoriasis in China, but its efficacy and safety have not been verified in a real-world environment. OBJECTIVES The primary objective was to investigate the efficacy and safety of Taz/BD cream in treating plaque psoriasis. The secondary objectives were to assess its relapse after discontinuation and the efficacy and safety profiles during retreatment. METHODS A prospective, multicenter, large-scale observational study was conducted. Adult patients with chronic plaque psoriasis involving <20% of the body surface area were enrolled. Taz/BD cream was applied once daily for 4 weeks. Patients who achieved ≥90% improvement in the Psoriasis Area and Severity Index (PASI) from baseline to week 4 were followed up to investigate relapse after drug withdrawal. Relapsed patients underwent another 4-week treatment. RESULTS In total, 2,299 eligible patients were enrolled, and 2,095 patients (91.1%) completed the 4-week study. The mean PASI improvement at week 4 was 53.7%, and the PASI 50/75 response rates were 62.5 and 26.8%, respectively. The mean PASI reduction in plaque induration, desquamation and erythema were 58.3, 61.0 and 40.0%, respectively (p < 0.001). Adverse reactions occurred in 445 patients (20.8%) at week 4. The most frequently reported adverse reactions were local skin irritation, including pruritus (10%), pain (6.7%), erythema (6.1%) and desquamation (1.8%). During the post-treatment period, 47 patients (24.0%) relapsed within 8 weeks after drug discontinuation. Forty-five patients were retreated for another 4 weeks, and the PASI 50/75 response rates were 72.7 and 40.9%, respectively. There were no unexpected safety signals during retreatment. CONCLUSION Taz/BD cream is effective and well tolerated in treating mild-to-moderate plaque psoriasis under near real-world conditions and demonstrates efficacy and safety during retreatment.

Abstract
BACKGROUND Fumaric acid esters (FAEs) are used to treat psoriasis and are known to cause lymphopenia in roughly 60% of the patients. Much remains to be elucidated about the biological effects of FAEs on lymphocytes. OBJECTIVE To evaluate the influence of long-term FAE (Fumaderm® ) treatment on peripheral blood CD4+ and CD8+ T cells, CD19+ B cells and CD56+ natural killer (NK) cells in psoriasis. METHODS In this single-centre retrospective observational subcohort study, we obtained leucocyte and lymphocyte subset counts before initiating FAE therapy in 371 psoriasis patients (mean age, 47.8 years; 63.3% males) and monitored them during treatment (mean treatment duration, 2.9 years). Multiparametric flow cytometry was used for immunophenotyping. RESULTS FAEs significantly reduced the numbers of CD4+ T, CD8+ T, CD19+ B and CD56+ NK cells. Among lymphocyte subsets, the mean percentage reduction from baseline was always highest for CD8+ T cells, with a peak of 55.7% after 2 years of therapy. The risk of T-cell lymphopenia increased significantly with the age of the psoriasis patients at the time that FAE therapy was initiated. It was significantly decreased for the combination therapy with methotrexate and folic acid (vitamin B9) supplementation. Supporting evidence was found suggesting that T-cell lymphopenia enhances the effectiveness of FAE therapy. CONCLUSIONS Monitoring distinct T-cell subsets rather than just absolute lymphocyte counts may provide more meaningful insights into both the FAE treatment safety and efficacy. We therefore suggest optimizing pharmacovigilance by additionally monitoring CD4+ and CD8+ T-cell counts at regular intervals, especially in patients of middle to older age. Thus, further prospective studies are needed to establish evidence-based recommendations to guide dermatologists in the management of psoriasis patients who are taking FAEs and who develop low absolute T-cell counts.

The Journal of dermatological treatment. 2019;(5):446-453
Abstract
Background: A specific sequence for psoriasis (PsO) therapy has not been defined. Objectives: This retrospective, observational cohort study characterized pathways of PsO treatment over 3 years for newly diagnosed patients initially treated with a topical medication. Methods: Adult PsO patients from the Explorys database (March 1 2011 to June 30 2015) were grouped according to medication-use patterns: 1) discontinued therapy; 2) topical therapy only; 3) switched/added an oral agent; and 4) switched/added a biologic agent. Results: Of 6875 patients, 907 (13.2%) discontinued treatment; 2544 (37.0%) used topical only, and 3319 (45.7%) and 819 (11.9%) switched/added-on an oral and/or biologic agent, respectively. Patients progressed to biologic treatment faster than to oral agents (median 254 vs. 378 d; p < .0001). Using an oral agent before a biologic significantly delayed biologic initiation compared to progressing to biologic directly from topical (median 456 vs. 90 d; p < .0001). Limitations: Disease severity and the reason for treatment transitions were not assessed. Conclusions: Patients initiating topical PsO treatment progressed to biologics faster than to oral agent using an oral agent prior to a biologic significantly delayed biologic initiation. Maintaining patients on an effective topical treatment may minimize the need for a switch to oral and biologics.

Skov, L, Thomsen, SF, Kristensen, LE, Dodge, R, Hedegaard, MS, Kjellberg, J
The British journal of dermatology. 2019;(1):100-107
Abstract
BACKGROUND There are limited data regarding causes of mortality in patients with psoriasis or psoriatic arthritis (PsA). OBJECTIVES This retrospective cohort study evaluated the risk and leading causes of mortality in patients with psoriasis or PsA. METHODS Individuals with a hospital-based diagnosis of PsA or psoriasis were identified using the Danish National Patient Registry. Matched control individuals were identified from the general population. The main outcome measures were risk of death and cause-specific mortality in patients with psoriasis or PsA. RESULTS Death rates per 1000 patient-years (with 95% confidence intervals) vs. controls were 22·3 (19·7-24·9) vs. 13·9 (11·8-16·0) for patients with psoriasis and 10·8 (8·9-12·8) vs. 11·6 (9·6-13·6) for patients with PsA. Survival, according to stratified hazard ratios (HRs), was significantly lower in patients with psoriasis than in controls (HR 1·74, P < 0·001), but not in patients with PsA (HR 1·06, P = 0·19). Significantly increased risk of death was observed in patients with psoriasis vs. controls due to a number of causes; the highest risks were observed for diseases of the digestive system; endocrine, nutritional and metabolic diseases; and certain infectious and parasitic diseases (HRs 3·61, 3·02 and 2·71, respectively). In patients with PsA, increased mortality was observed only for certain infectious and parasitic diseases (HR 2·80) and diseases of the respiratory system (HR 1·46). Patients with psoriasis died at a younger age than controls (mean age 71·0 vs. 74·5 years, P < 0·001). CONCLUSIONS Patients with severe psoriasis have increased mortality risk compared with matched controls, due to a number of causes. Evidence to support an increased risk for patients with PsA was less convincing.

Abstract
BACKGROUND AND OBJECTIVES Psoriasis is a chronic immunoinflammatory skin disease very frequent in the western world. Several authors have tried to calculate its prevalence in different regions, although most of them obtained the data from surveys and there are few publications from Mediterranean areas. The objective of our study was to analyze the prevalence and severity of psoriasis in Lleida (a northeastern region in Spain), identify age and sex specific differences and compare our results with other European series. MATERIALS AND METHODS A joint database of primary care medicine and the dermatology department was obtained from the entire province of Lleida with epidemiological data and psoriasis diagnosis and treatment codification. RESULTS A corrected database was obtained with 398,701 individuals and 6,868 of them (1.72%) were coded with the diagnosis of psoriasis. The prevalence was significantly higher in men than in women (1.88% vs 1.56%, OR=1.21, 95% CI: 1.15-1.27). The highest prevalence of psoriasis was found in the 61-70 years group (2.90%) and psoriasis in population under 18 years of age was 0.30%. In our sample, 7.27% of the patients were classified as moderate-severe psoriasis (499/6,868). CONCLUSION This study reports the prevalence and severity of psoriasis in a large Mediterranean region sample, obtaining the information through a electronic database. This study reveals a lower prevalence of psoriasis compared to other European countries, and the proportion of severe psoriasis (based on treatment criteria) is lower than in other studies. We emphasize that these differences could probably due to genetic background, life style and diet.

Abstract
BACKGROUND Psoriasis has been associated with metabolic syndrome and with an increased cardiovascular risk especially in patients with severe disease. The goal of this study was to estimate the prevalence of metabolic syndrome and other cardiovascular risk factors and its association with the psoriasis severity, sex and age. METHODS Consecutive patients with psoriasis were enrolled in a prospective study over a 1-year period. Blood samples were collected. Psoriasis area and severity index (PASI) and body surface area scores and two dermatology quality of life (DQOL) questionnaires were used to evaluate psoriasis severity and the impact of the disease. RESULTS Altogether 178 patients were included, of whom 44% had moderate-severe psoriasis. The overall prevalence of metabolic syndrome was 30% (men 34%, women 26%) without significant differences between patients with severe and mild disease. Age and menopause appeared to increase the risk for metabolic syndrome. Patients with severe psoriasis smoked more heavily, were more likely to have diabetes or insulin resistance and had higher homocysteine and lower high density lipoprotein cholesterol (HDL-C) levels than patients with mild psoriasis (P < 0.05). In women, a higher waist circumference was observed. Women had higher HDL-C levels and lower smoking and alcohol consumption rates. In accordance with the systematic coronary risk evaluation system, 18% of the patients had a high 10-year risk of fatal cardiovascular disease. CONCLUSIONS Psoriasis severity was associated with diabetes, insulin-resistance, smoking habit and higher cardiovascular risk. Metabolic syndrome was related to age and menopause but not to psoriasis severity.

Shawahna, R, Jaradat, NA
BMC complementary and alternative medicine. 2017;(1):4
Abstract
BACKGROUND Psoriasis is a frequent skin inflammatory disorder that inflicts millions of patients around the globe. To meet their healthcare needs, patients with psoriasis often seek treatment outside the allopathic paradigm. Use of medicinal plants has emerged as one of the most common and preferred modalities of complementary and alternative medicine (CAM). The aim of this study was to investigate the use of medicinal plants by patients with psoriasis in the West Bank of Palestine. METHODS The current study was a questionnaire based cross-sectional descriptive study on the use of medicinal plants by psoriasis patients in the West Bank of Palestine. A sample of 149 patients with psoriasis who were visiting outpatient clinics responded to the questionnaire in face to face interviews. RESULTS Medicinal plants were used by 81 (54.4%) patients with psoriasis. Patients used 33 medicinal plants belonging to 26 families. Plants belonging to Lamiaceae and Leguminosae were the most commonly used by the study patients. Aloe vera, Trigonella arabica, Catharanthus roseus and Anthemis cotula were the most frequently used medicinal plants to treat psoriasis. Leaves and fruits were the most commonly used parts by the study patients. Paste was the most commonly used form of preparation. The use of medicinal plants was significantly associated with age and monthly household income of the patients. Enhancement of immunity, improving conventional therapy and reduction of side effects were the most commonly self-reported reasons for using medicinal plants. CONCLUSIONS Patients with psoriasis in Palestine seem to use medicinal plants as a CAM modality to manage their psoriasis. Many medicinal plants were commonly used by patients with psoriasis. More randomized clinical trials are needed to demonstrate safety and efficacy for the majority of these medicinal plants reported to be used by patients with psoriasis in Palestine.

Abstract
BACKGROUND/AIMS: To assess the efficacy and tolerability of the new aerosol foam of calcipotriol 50 µg/g plus betamethasone dipropionate 0.5 mg/g (Cal/BD foam, Enstilar®) in psoriasis vulgaris under daily practice conditions. METHODS 410 adult psoriasis patients (56% male) from 87 German sites were enrolled in a 4-week, open-label, prospective, non-controlled, observational, non-interventional study. RESULTS At baseline, patients presented with a psoriasis severity of mild (41.81%), moderate (49.63%), and severe (8.31%) assessed by an investigator global assessment (IGA). After 4 weeks of treatment, 49% of the patients achieved an IGA of clear/almost clear. The mean affected body surface area was reduced from 12.91 to 7.55%, the PASI from 10.4 to 5.2 (p < 0.0001). 43% of the patients with severe IGA achieved treatment success (IGA = 0/1 and ≥2-step improvement). 93% of the patients did not show any adverse events. CONCLUSION The new Cal/BD foam showed a convincing efficacy and tolerability profile in daily practice, particularly in patients with severer disease manifestations.
