      Stangeland, Katarina Zak; Huldt-Nystrøm, Theis; Li, Xiaotong; Danielsen, Kjersti (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-09)
      Akne bør ikke oppfattes som en selvbegrensende ungdomsplage. På grunn av økende problemer med antibiotikaresistente bakterier anbefales restriktiv bruk av peroral og topikal antibiotika. Det finnes flere effektive midler for topikal behandling av lite til moderat uttalt akne. Ved uttalt, terapiresistent akne anbefales behandling med peroral isotretinoin.

    • Obesity and Staphylococcus aureus Nasal Colonization among Women and Men in a General Population 

      Olsen, Karina; Danielsen, Kjersti; Wilsgaard, Tom; Sangvik, Maria; Sollid, Johanna U. Ericson; Thune, Inger; Eggen, Anne Elise; Simonsen, Gunnar Skov; Furberg, Anne-Sofie (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Background: Obesity and diabetes mellitus (DM) have been linked to increased risk of infections, and Staphylococcus aureus nasal colonization is a major risk factor for developing infections with the microbe. We therefore sought to find whether body mass index (BMI) and waist circumference (WC) could be associated with S. aureus colonization independent of DM. Methodology: S. aureus colonization ...
    • Overweight and Weight Gain Predict Psoriasis Development in a Population-based Cohort 

      Danielsen, Kjersti; Wilsgaard, Tom; Olsen, Anne Olaug; Furberg, Anne-Sofie (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-07)
      Overweight is a proposed risk factor for psoriasis. How­ever, evidence from prospective studies is limited. The aim of this study was to investigate the association be­tween overweight, weight gain and risk of psoriasis, and potential synergism with smoking, within a population-based cohort including 8,752 individuals followed from 1994 up to 2008. There was a 32% increased odds of psoriasis from a ...
    • Prevalence of psoriasis and psoriatic arthritis and patient perceptions of severity in Sweden, Norway and Denmark: Results from the nordic patient survey of psoriasis and psoriatic arthritis 

      Danielsen, Kjersti; Duvetorp, Albert; Iversen, Lars; Østergaard, Mikkel; Seifert, Oliver; Tveit, Kåre Steinar; Skov, Lone (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-07)
      Optimal clinical management of psoriasis and psoriatic arthritis (PsA) Optimal clinical management of psoriasis and psoriatic arthritis (PsA) requires understanding of the impact on patients. The NORdic PAtient survey of Psoriasis and PsA (NORPAPP) aimed to obtain current data on disease prevalence and patient perceptions in Sweden, Denmark and Norway. Among 22,050 individuals questioned, the reported ...
    • Psoriasis, overweight and metabolic syndrome. The Tromsø Study 

      Danielsen, Kjersti (Doctoral thesis; Doktorgradsavhandling, 2014-05-28)
      Recently it has been suggested that the chronic inflammatory disease psoriasis is more than skin deep, as it has been associated with several comorbid conditions, including diabetes and cardiovascular disease. Increasing prevalence of psoriasis has been observed, possibly due to changes in lifestyle. Within the population-based Tromsø study cohort, we found an increase in the self-reported prevalence ...
    • Quality of life and contact with healthcare systems among patients with psoriasis and psoriatic arthritis: results from the NORdic PAtient survey of Psoriasis and Psoriatic arthritis (NORPAPP) 

      Duvetorp, Albert; Østergaard, Mikkel; Skov, Lone; Seifert, Oliver; Tveit, Kåre Steinar; Danielsen, Kjersti; Iversen, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-13)
      Psoriasis (skin psoriasis, PsO) is a chronic inflammatory condition. In about one-third of cases, the joints are affected (psoriatic arthritis, PsA). Both conditions, especially PsA, profoundly impact patients’ health-related quality of life (HRQoL). To describe the impact of psoriasis on HRQoL and patients’ contact with the healthcare system in Sweden, Denmark, and Norway, the NORdic PAtient survey ...
    • Staphylococcus aureus nasal carriage is associated with serum 25-hydroxyvitamin D levels, gender and smoking status. The Tromso Staph and Skin Study 

      Olsen, Karina; Falch, Birgit Margrethe; Danielsen, Kjersti; Johannessen, Mona; Sollid, Johanna U Ericson; Thune, Inger; Grimnes, Guri; Jorde, Rolf; Simonsen, Gunnar Skov; Furberg, Anne-Sofie (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Vitamin D induces the expression of antimicrobial peptides with activity against Staphylococcus aureus. Thus, we studied the association between serum 25-hydroxyvitamin D (25(OH)D) and S. aureus nasal colonization and carriage. Nasal swabs, blood samples and clinical data from 2,115 women and 1,674 men, aged 30–87 years, were collected in the Tromsø Staph and Skin Study 2007–08, as part of the ...
