Traditional cardiovascular risk factors, such as hypertension, dyslipidemia, and obesity, are more frequent in psoriatic patients ( 2-4 ). However, even after adjusting for these risk factors, psoriasis has been shown to be associated with a higher incidence of myocardial infarction, stroke, and cardiovascular mortality ( 3,5,6 ). In moderate to severe psoriasis, a signifi cantly deteriorated lipid profi le was observed compared with healthy controls, with higher values of low-density lipoprotein, triglycerides, and signifi cantly decreased HDL levels ( 7 ).Recent studies clearly demonstrated that infl ammation impairs reverse cholesterol transfer in vivo ( 8, 9 ), providing evidence that infl ammation impairs HDL function. Emerging evidence suggests that assessment of HDL plasma concentrations alone is insuffi cient and indicate that the quality, rather than the mere quantity, of HDL determines its potential benefi cial effects against atherosclerosis ( 10 ). HDL is a complex lipoprotein particle with a broad variety of functions, also exerting atheroprotective activity via effects on the endothelium and by potent antiinfl ammatory capabilities ( 11-13 ). Recent studies have identifi ed HDL-associated proteins to be involved in the regulation of lipid metabolism, complement activation, growth-factor secretion, and proteolysis (14)(15)(16)(17)(18)(19).Functional impairment of HDL may contribute to the increased cardiovascular mortality experienced by psoriatic patients, but the impact of psoriasis on the composition and function of HDL has not been assessed. As qualitative alterations of HDL seem to be linked with increased cardiovascular complications, we hypothesized that HDL from psoriatic patients displays altered protein cargo and lipid composition, thereby rendering HDL dysfunctional.Abstract Psoriasis, a chronic infl ammatory skin disease, has been linked to increased myocardial infarction and stroke. Functional impairment of HDL may contribute to the excess cardiovascular mortality of psoriatic patients. However, data available regarding the impact of psoriasis on HDL composition and function are limited. HDL from psoriasis patients and healthy controls was isolated by ultracentrifugation and shotgun proteomics, and biochemical methods were used to monitor changed HDL composition. We observed a signifi cant reduction in apoA-I levels of HDL from psoriatic patients, whereas levels of apoA-II and proteins involved in acute-phase response, immune response, and endopeptidase/protease inhibition were increased. Psoriatic HDL contained reduced phospholipid and cholesterol. With regard to function, these compositional alterations impaired the ability of psoriatic HDL to promote cholesterol effl ux from macrophages. Importantly, HDLcholesterol effl ux capability negatively correlated with psoriasis area and severity index. We observed that control HDL, as well as psoriatic HDL, inhibited dihydrorhodamine (DHR) oxidation to a similar...

Summary Background Drug survival rates reflect efficacy and safety and may be influenced by the availability of alternative treatment options. Little is known about time‐dependent drug survival in psoriasis and the effect of increasing numbers of biologic treatment options. Objectives To determine whether drug survival is influenced by the availability of treatment options and by factors such as gender, psoriatic arthritis or previous biologic treatment. Methods This observational, retrospective, multicentre cohort study analysed data from patients registered in the Austrian Psoriasis Registry (PsoRA) who were treated with biologics between 1 January 2015 and 30 November 2019. Results A total of 1572 patients who received 1848 treatment cycles were included in this analysis. The highest long‐term Psoriasis Area and Severity Index improvement was observed after treatment with ixekizumab, followed by ustekinumab and secukinumab, adalimumab and etanercept. Overall, ustekinumab surpassed all other biologics in drug survival up to 48 months. However, when adjusted for biologic naïvety, its superiority vanished and drug survival rates were similar for ixekizumab (91·6%), secukinumab (90·2%) and ustekinumab (92·8%), all of them superior to adalimumab (76·5%) and etanercept (71·9%) at 12 months and beyond. Besides biologic non‐naïvety (2·10, P < 0·001), the introduction of a new drug such as secukinumab or ixekizumab (relative hazard ratio 1·6, P = 0·001) and female gender (1·50, P = 0·019) increased the risk of treatment discontinuation overall, whereas psoriatic arthritis did not (1·12, P = 0·21). Conclusions The time‐dependent availability of drugs should be considered when analysing and comparing drug survival. Previous biologic exposure significantly influences drug survival. Women are more likely to stop treatment.

Psoriasis is a chronic inflammatory disorder associated with increased cardiovascular mortality. Psoriasis affects high-density lipoprotein (HDL) composition, generating dysfunctional HDL particles. However, data regarding the impact of anti-psoriatic therapy on HDL composition and function are not available. HDL was isolated from 15 psoriatic patients at baseline and after effective topical and/or systemic anti-psoriatic therapy and from 15 age- and sex-matched healthy controls. HDL from psoriatic patients showed a significantly impaired capability to mobilize cholesterol from macrophages (6.4 vs. 8.0% [(3)H]cholesterol efflux, P<0.001), low paraoxonase (217 vs. 350 μM(-1) minute(-1) mg(-1) protein, P=0.011) and increased Lp-PLA2 activities (19.9 vs. 12.1 nM(-1) minute(-1) mg(-1) protein, P=0.028). Of particular interest, the anti-psoriatic therapy significantly improved serum lecithin-cholesterol acyltransferase activity and decreased total serum lipolytic activity but did not affect serum levels of HDL-cholesterol. Most importantly, these changes were associated with a significantly improved HDL-cholesterol efflux capability. Our results provide evidence that effective anti-psoriatic therapy recovers HDL composition and function, independent of serum HDL-cholesterol levels, and support to the emerging concept that HDL function may be a better marker of cardiovascular risk than HDL-cholesterol levels.

As shown by retrospective analysis, the primary efficacy of FAE was similar to that of MTX under daily life conditions.

This retrospective multicentre analysis from the Psoriasis Registry Austria (PsoRA) was conducted to determine drug effectiveness and survival of anti-tumour necrosis factor alpha (anti-TNF-α) agents in patients with moderate-to-severe chronic plaque psoriasis over a 9-year period. Data on 1,019 treatment cycles with adalimumab (n = 460), etanercept (n = 501), and/or infliximab (n = 58) administered to 827 patients (272 women, 555 men) were available for analysis. Compared with etanercept, adalimumab and infliximab showed superior short-term effectiveness. Intention-to-treat-calculated median drug survivals for adalimumab (1,264 days) and etanercept (1,438 days) were similar to each other (p = 0.74), but significantly superior to that of infliximab (477 days) (p = 7.0e-07 vs. adalimumab and p=2.2e-07 vs. etanercept, respectively). Their drug survival rates at 36 months were 51.6%, 56.0%, and 22.6%, respectively. Survival rates correlated significantly with effectiveness for adalimumab and etanercept, but not for infliximab.

Retrospective analysis of registry data revealed that the primary efficacy of PUVA was superior to that of certain biologics. Prospective head-to-head studies of PUVA and biologics are warranted to confirm these observations.

Treatment with 311-nm UVB accelerates the clearance of psoriatic lesions in ustekinumab-treated patients.

Acquired reactive perforating collagenosis is a perforating dermatosis usually associated with different systemic diseases, mainly diabetes mellitus and/or chronic renal insufficiency. Different therapies have been tried but treatment is not standardized yet and remains a challenge. In the last few years, allopurinol has been reported as a good therapeutic option for acquired reactive perforating collagenosis. We describe the case of a 73-year-old man affected by acquired reactive perforating collagenosis associated with diabetes type 1 and chronic renal failure with secondary hyperparathyroidism. The patient was successfully treated with allopurinol 100mg once/day p.o..
