Decreased prevalence of atopic features in patients with psoriatic arthritis, but not in psoriasis vulgaris

High Serum IgE Concentration in Patients with Psoriasis

“…The IgE levels were also higher in PsA patients in our study, but the difference between PsA and PV was not statistically significant. Nevertheless, a retrospective study observed that psoriatic patients with joint symptoms had higher IgE levels and another study found completely opposite result [21,22]. Our data were also in contrast to other researches showing no increase of IgE levels in psoriasis [12,13].…”

Investigation of Atopy in Primary Cutaneous CD30+ T-Cell Lymphoproliferative Disorders

“…This was true for LyP-C patients (P= 0.014) but not for LyP-A, LyP-B nor pcALCL. However, the strong family history of atopy recorded for patients with LyP-C (12/36 or 33%) was not statistically higher than the 27% frequency for 147 adult controls reported by Hajdarbegovic (P= 0.537) [28].…”

Association between psoriasis and asthma risk: A meta-analysis

“…After subgroup analysis based on the design of selected studies or ethnicity, we were still unable to find the possible sources of clinical heterogeneity and methodologic heterogeneity. Interestingly, the sensitivity analysis indicated that the study by Fang et al 8 study and the study by Hajdarbegovic et al 22 might be the main source of heterogeneity (data not shown). Second, only two studies investigated the risk of asthma susceptibility in patients with psoriasis at different ages 8,20 and stages, 8,13 and two studies were not powerful enough to perform further analysis.…”

“…There were three retrospective cohort studies 8,13,19 and three cross-sectional cohort studies. 20 -22,25 As for ethnicity, three studies investigated white populations, 19,20,22,25 three studies investigated Asian populations. 8,13,21 All the studies included patients of all ages, and two studies provided detailed incidences of asthma at different ages.…”

“…Three studies were deemed to be high quality (7-9 stars), 8,13,21 whereas the other three studies were deemed to be of medium quality (4 -6 stars). 19,20,22,25 …”
