Prolonged Sick Leave Before and After Diagnosis of Generalized Pustular Psoriasis: A Swedish Population-based Register Study.

The aim of this study was to analyse sick leave in generalized pustular psoriasis, the most severe form of pustular psoriasis. Prolonged sick leave of >14 days was analysed for 502 patients with generalized pustular psoriasis compared with controls with psoriasis vulgaris and matched controls from the general population. Using data from the Swedish National Patient Register, and the Longitudinal integrated database for health insurance and labour market studies, the study estimated the mean number of sick leave days in the year of first diagnosis of generalized pustular psoriasis (index year) and for 2 years before and after the index year.

Psoriasis Involving Special Areas is Associated with Worse Quality of Life, Depression, and Limitations in the Ability to Participate in Social Roles and Activities.

Background: Psoriasis severity has traditionally been categorized as mild, moderate, and severe. Commonly, cut-offs for severe disease require a body surface area (BSA) involvement of ≥10% or a Psoriasis Area Severity Index (PASI) > 10. However, clinical experience challenges these traditional measures and requirements, as patients with less extensive psoriasis may have disease that severely impacts quality of life.

Patient reported experiences of Swedish patients being investigated for cancer during the Covid-19 pandemic.

Background: Patient reported experiences in individuals being investigated for cancer have been recorded in a nationwide survey in Sweden, providing an opportunity to assess the impact of the Covid-19-pandemic.

Material And Methods: Questionnaires from 45920 patients were analyzed to assess the experience of being investigated for cancer. Data from before the Covid-19-pandemic (2018-2019) was compared to data acquired during the pandemic (2020-2021), using chi-square and Wilcoxon rank sum tests.

Economic Burden of Palmoplantar Pustulosis in Sweden: A Population-based Register Study.

The aim of this study was to estimate the economic burden of palmoplantar pustulosis, a chronic relapsing skin condition commonly occurring in combination with psoriasis vulgaris. Using data from the Swedish National Patient Register and Swedish Prescribed Drug Register for 2015, the study estimated all-cause and palmoplantar pustulosis-specific healthcare resource use (inpatient stays, physician visits and drug use) for 14,715 patients with palmoplantar pustulosis, and compared these both with matched controls from the general population and with patients with psoriasis vulgaris (without palmoplantar pustulosis). Mean annual direct costs for a patient with palmoplantar pustulosis was higher compared with costs for the general population (3,000 vs 1,700 Euro, p < 0.

The Use of IL-17 and IL-23 Inhibitors in Swedish Clinical Practice: A Register-Based Analysis.

Background: Interleukin (IL) inhibitors have made completely cleared skin achievable for many patients with moderate to severe psoriasis in clinical trial settings. Few observational studies assess treatment response in accordance with treatment goals in guidelines.

Objectives: The aim of the study was to analyze the treatment response of IL-17/IL-23 inhibitors in clinical practice and the proportions of patients that reach the treatment target of the Psoriasis Area and Severity Index (PASI) < 3 and the Dermatology Life Quality Index (DLQI) ≤5.

Economic Burden of Generalized Pustular Psoriasis in Sweden: A Population-Based Register Study.

Background: Generalized pustular psoriasis (GPP), which can occur with or without psoriasis vulgaris (PV), is a severe form of pustular psoriasis with potentially life-threatening symptoms. GPP is also associated with several comorbidities, which further adds to the burden of disease. This study investigates the economic burden of disease in patients with GPP.

Perception of information to Swedish melanoma patients in routine clinical practice - a cross-sectional survey.

Background: Comprehensible, relevant information empowers patients, allowing them to take an active part in their care. We aim to investigate how Swedish melanoma patients perceive information provided in routine clinical practice and explore the correlation between satisfaction with information, symptoms and functioning scales, and quality of life.

Methods: A cross-sectional study where EORTC QLQ-C30, EORTC QLQ-INFO25 and EQ-5D-3L questionnaires were sent to 1213 patients by post and 792 responded (65%).

Long-Term Risk of Skin Cancer and Lymphoma in Users of Topical Tacrolimus and Pimecrolimus: Final Results from the Extension of the Cohort Study Protopic Joint European Longitudinal Lymphoma and Skin Cancer Evaluation (JOELLE).

Purpose: Evidence is insufficient to infer whether topical calcineurin inhibitors (TCIs; tacrolimus and pimecrolimus) cause malignancy. The study objective was to estimate the long-term risk of skin cancer and lymphoma associated with topical TCI use in adults and children, separately.

Patients And Methods: A cohort study in Denmark, Sweden, UK, and the Netherlands was conducted.

Prevalence and incidence of generalized pustular psoriasis in Sweden: a population-based register study.

Background: Generalized pustular psoriasis (GPP) is a severe form of pustular psoriasis with generalized eruption of sterile pustules, often along with systemic symptoms. There is a scarcity of population-based estimates of GPP prevalence and incidence.

Objectives: To estimate (i) the prevalence and incidence of GPP in the Swedish general population and (ii) the prevalence of psoriasis vulgaris within the GPP population.

Impact of Bariatric Surgery on Moderate to Severe Psoriasis: A Retrospective Nationwide Registry Study.

Studies of the effects of bariatric surgery on psoriasis are few, with conflicting results. By linking the Swedish National Register for Systemic Treatment of Psoriasis (PsoReg) with the Scandinavian Obesity Surgery Registry (SOReg), individuals with psoriasis who had undergone bariatric surgery in Sweden during 2008 to 2018 were identified, and matched with data for patients with psoriasis in PsoReg. Psoriasis Area Severity Index (PASI) and Dermatology Life Quality Index (DLQI) were compared between the groups.

Prevalence and incidence of palmoplantar pustulosis in Sweden: a population-based register study.

Paediatric infections in the first 3 years of life after maternal anti-TNF treatment during pregnancy.

Background: Most anti-tumour necrosis factor (anti-TNF) agents are transferred across the placenta and may increase paediatric susceptibility to infections.

Aims: To assess the risk of paediatric infections after maternal anti-TNF treatment.

Methods: Population-based cohort study in Denmark, Finland and Sweden 2006-2013 in which 1027 children born to women with rheumatoid arthritis, psoriasis, psoriatic arthritis, ankylosing spondylitis or inflammatory bowel disease, treated with anti-TNF, and 9346 children to women with non-biologic systemic treatment, were compared to 1 617 886 children of the general population.

Association of Skin Psoriasis and Somatic Comorbidity With the Development of Psychiatric Illness in a Nationwide Swedish Study.

Importance: Psoriasis is a complex systemic disease with skin involvement, somatic comorbidity, and psychiatric illness (PI). Although this view of psoriasis is widely accepted, potential synergies within this triad of symptoms have not been adequately investigated.

Objectives: To investigate the independent association of skin psoriasis and somatic comorbidity with the development of PI and to assess whether skin psoriasis and somatic comorbidity act synergistically to produce a risk of PI that is greater than the additive associations.
