Generalized erythrodermic psoriasis (GEP) is a rare and potentially life‐threatening variant of psoriasis. Possible triggers that have been identified to date include poorly controlled psoriasis, medications, abrupt discontinuation of anti ‐ psoriatic treatment, and underlying systemic illnesses. However, vaccines have rarely been reported to exacerbate GEP. Herein, we report two unique cases with GEP exacerbated following a dose of the BNT162b2 mRNA vaccine for COVID‐19 (as their second dose, the first being the mRNA‐1273 vaccine). Based on our observations and a literature review, vaccination was considered the most likely trigger of GEP due to the close temporal relationship between the second vaccination and the onset of GEP.

The cutaneous side effects of COVID‐19 vaccines are being studied and their immunogenicity is most likely linked to the pathophysiology of psoriasis. Although uncommon, several cases of exacerbation and new onset of psoriasis have been reported globally after vaccination. To contribute to the literature on this intriguing topic, we present three cases of de novo psoriasis in adult patients following COVID‐19 vaccination. Our observations and a literature review show that this occurrence is independent of the type and brand of vaccines.

Introduction: Plaque psoriasis (PsO), characterized by demarcated, erythematous, scaly skin, can have a substantial negative impact on patients' quality of life. This observational (noninterventional) retrospective study was conducted to characterize treatment patterns and response among patients with plaque PsO treated with secukinumab under routine medical practice in Vietnam. Methods: Patient medical records from the specialized clinic of the Ho Chi Minh City Hospital of Dermato-Venereology (N = 236) were collected. Patients (male or female) aged C 18 years with moderate-to-severe chronic plaque PsO, defined as [ 10% involvement of the body surface area (BSA [ 10) or a Psoriasis Area and Severity Index (PASI) score [ 10 and a Dermatology Life Quality Index (DLQI) score [ 10, were included. Results: In total, 230 patients met the inclusion criteria and were included in the intention-to-treat (ITT) population, the majority of whom were men (66.1%). At baseline, the mean ± standard deviation (SD) age of the ITT population was 41.46 ± 14.29 years, mean disease duration was 7.91 ± 7.91 years, and 27% (n = 62) were obese. More than 90% of the patients were biologic naïve prior to initiation of secukinumab therapy. At week 4, 54.6% patients (n = 124) achieved C 75% reduction in PASI scores from baseline (PASI 75). By week 16, 81.1, 68.9, and 36.5% of the overall population (n = 180, 153, and 81) achieved PASI scores of 75, 90, and 100, respectively; 66.1% of the overall population (n = 154) reported DLQI scores of 0/1 by week 16. The effectiveness of secukinumab was validated in subgroups of patients with or without obesity, concomitant conditions (hepatitis B virus, hepatitis C virus, diabetes, high blood pressure, gout, and/or obesity [body mass index C 30 kg/m 2 ]), and concomitant psoriatic arthritis (PsA). Conclusion:The study validated the real-world effectiveness of secukinumab in Vietnamese patients irrespective of obesity, concomitant conditions, and concomitant PsA status.

Introduction: Psoriasis (PsO), an immune-mediated inflammatory skin disorder, has substantial negative impact on patients' quality of life. Secukinumab, an approved treatment for moderate-to-severe plaque PsO, has an established long-term efficacy and safety profile. This study aims to provide real-world evidence of long-term effectiveness and retention rate of secukinumab in Vietnamese patients with PsO. Methods: This retrospective, observational study collected medical records of adult patients with moderate-to-severe PsO receiving secukinumab treatment from Ho Chi Minh City Hospital of Dermato-Venereology. The primary objective was to evaluate secukinumab effectiveness in PsO as measured by 75% improvement in psoriasis area and severity index (PASI 75) at month 12. Secondary objectives were

Introduction: Since the early 20th century, findings have demonstrated that psoriasis is frequently associated with atherosclerosis and cardiovascular diseases. The Carotid Intima-Media Thickness (CIMT) is a surrogate marker of atherosclerotic vascular disease. Objective: The aim of this study was to investigate the CIMT in patients with psoriasis and investigate its correlation with the clinical features. Methods: The present case-control study involved 70 patients with psoriasis who visited Ho Chi Minh City Hospital of Dermato-Venereology from September 2018 to April 2019 and 35 healthy subjects. Serum triglyceride, total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol levels were measured in both groups. Linear Doppler scanning was performed to evaluate the CIMT of the common, internal, and external carotid arteries and the presence of atherosclerotic plaques. Results: The mean CIMT value in psoriasis patients was significantly higher than that of controls [0.59 mm (0.53 - 0.71) vs. 0.54 mm (0.52 - 0.62), respectively, p = 0.036]. Multiple linear regression analysis revealed a significant correlation between the CIMT and age (p = 0.043) and CIMT and the Psoriasis Area and Severity Index (p < 0.0001). Moreover, the mean number of atherosclerotic plaques in psoriasis patients was significantly higher than that in controls [0.27 ± 0.68 vs. 0.03 ± 0.17, respectively, p = 0.035]. Conclusion: Elderly patients with severe psoriasis should be evaluated carefully regarding CIMT and atherosclerotic plaques, as these signs are representative of increased cardiovascular risk.
