- Dermatitis herpetiformis has been investigated in the past; however, only a limited number of studies have reported its incidence based on validated nationwide population-based registries. To address this gap, the aims of this study are to estimate the incidence of dermatitis herpetiformis in Sweden and to validate the National Patient Register (NPR) for diagnosis of dermatitis herpetiformis. A population-based open cohort study was conducted, including all patients diagnosed with dermatitis herpetiformis (International Classification of Diseases 10th revision; ICD-10 code L13.0) in Sweden from 2005 to 2018 (n = 1,724), identified from the NPR. The diagnosis of dermatitis herpetiformis in the NPR was validated using medical records, histopathological and immunopathological data, yielding a positive predictive value (PPV) of 62.5%. The mean annual incidence of dermatitis herpetiformis was 0.93/100,000 (95% confidence interval 0.79–1.08), female to male ratio 1:1, and mean age at diagnosis 60.9 years. In conclusion, this large nationwide cohort study showed a low validity for diagnosis of dermatitis herpetiformis in the NPR, and the adjusted incidence rate of dermatitis herpetiformis in Sweden was estimated to be 0.93/100,000, which is lower than that in previous Swedish studies.

Tidskriftsartikel (refereegranskat)abstract
- Evidence about the association of bullous pemphigoid and the risk of cancer is conflicting. Patients diagnosed with bullous pemphigoid (n = 5,739) between 2005 and 2016 were matched with a control cohort from the general population (n = 17,168) to estimate their overall and specific risk of cancer. The risk of squamous cell cancer of the skin (cSCC) was increased in patients with bullous pemphigoid (hazard ratio (HR) 1.3; 95% confidence interval (CI) 1.1-1.6). The risk of lymphoma within one year after bullous pemphigoid diagnosis was also increased (HR 3.1; 95% CI 1.3-7.6). While overall cancer risk prior to diagnosis of bullous pemphigoid was similar in cases and controls (prevalence odds ratio (POR) 1.0; 95% CI 0.9-1.0), the risk of male genital cancer within one year prior to diagnosis of bullous pemphigoid was lower in cases (POR 0.4; 95% CI 0.2-0.8). Clinicians must be aware of the increased risk of cSCC and lymphoma in patients with bullous pemphigoid.

Tidskriftsartikel (refereegranskat)abstract
- SwedAD, a Swedish nationwide registry for patients with atopic dermatitis receiving systemic pharmacotherapy, was launched on 1 September 2019. We describe here the establishment of a user-friendly registry to the benefit of patients with atopic dermatitis. By 5 November 2022, 38 clinics had recorded 931 treatment episodes in 850 patients with an approximate national coverage rate of 40%. Characteristics at enrolment included median Eczema Area and Severity Index (EASI) 10.2 (interquartile range 4.0, 19.4), Patient-Oriented Eczema Measure (POEM) 18.0 (10.0, 24.0), Dermatology Life Quality Index (DLQI) 11.0 (5.0, 19.0) and Peak Itch Numerical Rating Scale-11 (NRS-11) 6.0 (3.0, 8.0). At 3 months, median EASI was 3.2 (1.0, 7.3) and POEM, DLQI, and NRS-11 were improved. Regional coverage varied, reflecting the distribution of dermatologists, the ratio of public to private healthcare, and difficulties in recruiting certain clinics. This study highlights the importance of a nationwide registry when managing systemic pharmacotherapy of atopic dermatitis.

Tidskriftsartikel (refereegranskat)abstract
- Studies have shown differences in the skin and gut bacterial microbiomes in patients with psoriasis, but the pharyngeal microbiome has not been studied previously. The aim of this study was to investigate differences in the bacterial microbiome of the pharynx and skin of patients with psoriasis compared with healthy controls. Swabs were taken from the pharynx and el-bow skin of 39 patients with psoriasis and 70 controls. Microbiomes were characterized by sequencing 16S rRNA genes on the Illumina MiSeq platform. Significant differences were found in alpha and beta diversity in the skin, but not in the pharynx. Significant differences were also found between several phyla and genera in both skin and pharynx. The severity of psoriasis did not correlate with any genera in the pharynx, but with Capnocytophaga, Leptotrichia, Abiotrophia and Tannerella in the skin. The composition of the pharyngeal and skin microbiome may be of importance in the pathogenesis of psoriasis.

Relationship between Eczema and Self-reported Difficulties Keeping up with School Education : A Cross-sectional Study
- 2023
-
Ingår i: Acta Dermato-Venereologica. - : Medical Journals Sweden. - 0001-5555 .- 1651-2057. ; 103

Tidskriftsartikel (refereegranskat)abstract
- Eczema is a common chronic disease that affects both children and adults, and may have an adverse impact on school performance, as it is characteristically pruri-tic, and hence may lead to poor concentration and ina-dequate sleep. The aim of this study was to elucidate the relationship between eczema and self-reported difficulties keeping up with school education. The study was based on cross-sectional questionnaire data collec-ted in schools among all 9th graders (15–16 years old) within a Swedish county. Logistic regression analyses were used to assess the association between having eczema and self-reported difficulties keeping up with school education. A total of 2,620 pupils participated (50.1% female). An increased odds ratio (OR) of self-reported difficulties keeping up with school education was found in adolescents with eczema compared with those without eczema after adjustment for sex and family residence (OR 2.13, 95% confidence interval (95% CI) 1.32–3.44), and with additional adjustment for sleeping problems, attention-deficit hyperactivity disorder, allergy, rhinitis, asthma, and alcohol con-sumption (adjusted OR 1.78, CI 1.05–3.00). Eczema may be a relevant risk factor for difficulty keeping up with school education in adolescents. However, studies that can assess temporality, based in different settings with objective reports of both eczema and self-reported difficulties at school, are needed to con-firm these findings.

Role of Mannose-binding Lectin and Association with Microbial Sensitization in a Cohort of Patients with Atopic Dermatitis
- 2023
-
Ingår i: Acta Dermato-Venereologica. - : Medical Journals Sweden AB. - 1651-2057 .- 0001-5555. ; 103, s. 1-5

Tidskriftsartikel (refereegranskat)abstract
- Atopic dermatitis is a relapsing inflammatory skin condition, in which bacteria, fungi and viruses may colonize the skin and aggravate the condition. Mannose-binding lectin is part of the innate immune system. Polymorphism in the mannose-binding lectin gene can result in deficiency of mannose-binding lectin, which may affect defence against microbes. The aim of this study was to investigate whether polymorphisms in the mannose-binding lectin gene affect the extent of sensitization to common skin microbes, the skin barrier function, or the severity of the disease in a cohort of patients with atopic dermatitis. Genetic testing of mannose-binding lectin polymorphism was performed in 60 patients with atopic dermatitis. The disease severity, skin barrier function, and serum levels of specific immunoglobulin E against skin microbes were measured. In patients with low mannose-binding lectin genotype (group 1) 6 of 8 (75%) were sensitized to Candida albicans, compared to 14 of 22 (63.6%) patients with intermediate mannose-binding genotype (group 2) and 10 of 30 (33.3%) patients with high mannose-binding genotype (group 3). Group 1 (low mannose-binding lectin) was more likely to be sensitized to Candida albicans compared with group 3 (high mannose-binding lectin) (odds ratio 6.34, p-value 0.045). In this cohort of patients with atopic dermatitis, mannose-binding lectin deficiency was associated with increased sensitization to Candida albicans.

Clinicopathological Factors Associated with Incomplete Excision of High-risk Basal Cell Carcinoma
- 2021
-
Ingår i: Acta Dermato-Venereologica. - : Medical Journals Sweden AB. - 0001-5555 .- 1651-2057. ; 101
-
Tidskriftsartikel (refereegranskat)abstract
- Research has shown higher rates of incomplete excision among high-risk than low-risk basal cell carcinomas, but data is limited. A single-centre, retrospective study including excised high-risk basal cell carcinomas (type II-III according to the Swedish classification) was performed to determine incomplete excision rates and associated clinicopathological risk factors. Overall, 987 consecutive cases were included. Of these, 203 (20.6%) were incompletely excised. Incomplete excision rates were higher for type III basal cell carcinomas (27.0% vs 17.6% for type II, p < 0.001) and localization on the face and scalp (22.4% vs 14.7% for other locations, p = 0.009), especially on the nose, ear, scalp and periorbital area (28.0-37.0% vs 9.5-16.9% for other locations, p < 0.0001). Circular excisions were also more often incomplete (28.5%) compared with elliptical excisions (17.7%) (p < 0.001). No association was found between incomplete excision rates and tumour size, excision margins, use of a pre-operative biopsy or surgeon experience. Mohs micrographic surgery should be used more often for type II-III basal cell carcinomas on the face and scalp.

Tidskriftsartikel (refereegranskat)abstract
- Hailey-Hailey disease is a rare hereditary skin disease caused by mutations in the ATP2C1 gene encoding the secretory pathway Ca2+/Mn2+-ATPase 1 (SPCA1) protein. Extracutaneous manifestations of Hailey-Hailey disease are plausible but still largely unknown. The aim of this study was to explore the association between Hailey-Hailey disease and diabetes. A population-based cohort study of 347 individuals with Hailey-Hailey disease was performed to assess the risks of type 1 diabetes and type 2 diabetes, using Swedish nationwide registries. Pedigrees from 2 Swedish families with Hailey-Hailey disease were also investigated: 1 with concurrent type 1 diabetes and HLA-DQ3, the other with type 2 diabetes. Lastly, a clinical cohort with 23 individuals with Hailey-Hailey disease and matched healthy controls was evaluated regarding diabetes. In the register data males with Hailey-Hailey disease had a 70% elevated risk of type 2 diabetes, whereas no excess risk among women could be confirmed. In both pedigrees an unusually high inheritance for diabetes was observed. In the clinical cohort, individuals with Hailey-Hailey disease displayed a metabolic phenotype indicative of type 2 diabetes. Hailey-Hailey disease seems to act as a synergistic risk factor for diabetes. This study indicates, for the first time, an association between Hailey-Hailey disease and diabetes and represents human evidence that SPCA1 and the Golgi apparatus may be implicated in diabetes pathophysiology.
