Risk of infections in psoriasis: assessment and challenges in daily management

Impact of COVID-19 on Influenza and Pneumococcal Vaccination of Psoriatic Patients in Germany: Results from Vac-Pso

BACKGROUND

Suboptimal influenza and pneumococcal vaccination rates have been reported before the COVID-19 pandemics in certain populations at risk for severe infection. The aim of this longitudinal cohort study was to investigate changes in influenza and pneumococcal vaccination rates and patient perceptions in patients with psoriasis (PsO) before and during the pandemic.

METHODS

Data on vaccination, patient and disease characteristics, comorbidity, and patient perceptions were collected with questionnaires before and during the pandemic approximately one year later.

RESULTS

Over the whole cohort who participated in the follow-up visit (n = 287; 59.2% male; mean age: 56.3 years), both influenza and pneumococcal lifetime vaccination prevalences increased significantly from 50.5% to 66.2% and from 16.0% to 41.5%, respectively. A total of 88.5% of PsO patients were interested in a COVID-19 vaccination or had already received it. The reasons for and against vaccinations changed significantly before and during the pandemic.

CONCLUSIONS

Despite a promising increase in the vaccination prevalence in our PsO cohort, it remains important that awareness for vaccinations is encouraged and closely monitored in future research, particularly in populations at risk.

Psoriasis and COVID-19 Infection Negatively Impact Each Other: An Analysis of 3581 Cases

Objective

To determine whether COVID-19 infection and psoriasis impact each other.

Methods

WeChat app was used to carry out a questionnaire survey in individuals aged 18 years and over.

Results

A total of 3581 individuals, including 2515 individuals without psoriasis and 1066 psoriatic patients completed the survey. The rate of COVID-19 infection was significantly higher in psoriatic patients than in those without psoriasis (89.59% vs 77.93%, p < 0.0001). Moreover, the rate of relapse and/or worsening of psoriasis was higher in psoriatic patients with COVID-19 infection than in that without COVID-19 infection (75.29% vs 47.75%, p < 0.0001).

Conclusion

COVID-19 infection and psoriasis negatively impact each other.

Patient Preference for Biologic Treatments of Psoriasis in the Chinese Setting

OBJECTIVE

Assessments of patients' preferences can support in clinical decision-making regarding biologic therapies for psoriasis. Our objective was to investigate patient preference for biologic treatments in patients with psoriasis in China.

METHODS

From October 2020 to January 2021, psoriasis patients were recruited for a survey that included demographic and disease-related questions, as well as a discrete choice experiment to measure their preferences for biologic therapy. A discrete-choice experiment was used in which respondents selected psoriasis treatments based on benefits (ie, early onset of efficacy, long-term efficacy, sustained efficacy) and treatment costs. We analyzed choice data using conditional logit model.

RESULTS

This study included 236 patients with moderate-to-severe psoriasis. The relative importance of the cost of biologic treatments, probability of keeping PASI100 at 5 years, probability of achieving PASI100 at 3 months and time to achieve PASI50 after initiation the biologic treatment were 0.593, 0.137, 0.185 and 0.085. Over 50% of patients regarded the cost of biologic treatments as the most important attribute. High-income and low-income subgroups had higher preference weight in probability of achieving PASI100 at 3-month and monthly cost.

CONCLUSION

The cost of biologic treatments was found as the most important attribute for Chinese patients with psoriasis. Among efficacy attributes, the probability of achieving PASI100 at 3 months showed most sensitive. These results may be helpful to understand patient preference for biologic treatments used for psoriasis in China.
