Forskningsöversikt (refereegranskat)abstract
- Chronic prurigo (CPG) is a highly burdensome pruritic disease characterized by chronic itch, a prolonged scratching behavior and the development of localized or generalized hyperkeratotic pruriginous lesions. Neuronal sensitization and the development of an itch-scratch cycle contribute to the augmentation of pruritus and the chronicity of the disease. We provide here the first international guideline for a rational diagnostic and therapeutic approach for CPG. Recommendations are based on available evidence and expert opinion. The diagnosis of CPG is made clinically. A detailed medical history together with laboratory and radiological examinations are advised in order to determine the severity of CPG, identify the underlying origin of the itch and assist in the elaboration of a treatment plan. Therapeutically, it is advised to adopt a multimodal approach, including general strategies to control itch, treatment of the underlying pruritic conditions, and of the pruriginous lesions. Topical (corticosteroids, calcineurin inhibitors, capsaicin) and systemic antipruritic agents (eg, gabapentinoids, immunosuppressants, and opioid modulators) as well as physical treatment modalities (phototherapy, cryotherapy) should be employed in a step-wise approach. Psychosomatic or psychological interventions may be recommended in CPG patients with signs of psychiatric/psychological comorbidities.

- Sensitive skin is a frequent complaint in the general population, in patients, and among subjects suffering from itch. The International Forum for the Study of Itch (IFSI) decided to initiate a special interest group (SIG) on sensitive skin. Using the Delphi method, sensitive skin was defined as “A syndrome defined by the occurrence of unpleasant sensations (stinging, burning, pain, pruritus, and tingling sensations) in response to stimuli that normally should not provoke such sensations. These unpleasant sensations cannot be explained by lesions attributable to any skin disease. The skin can appear normal or be accompanied by erythema. Sensitive skin can affect all body locations, especially the face”. This paper summarizes the background, unresolved aspects of sensitive skin and the process of developing this definition.

Chronic Nodular Prurigo : A European Cross-sectional Study of Patient Perspectives on Therapeutic Goals and Satisfaction
- 2021

Tidskriftsartikel (refereegranskat)abstract
- Chronic nodular prurigo is characterized by recalcitrant itch. Patient perspectives on therapeutic goals, satisfaction with therapy and efficacy of therapeutic regimens for this condition are unknown. This questionnaire study examined these issues in 406 patients with chronic nodular prurigo from 15 European dermatological centres. Improvements in itch, skin lesions and sleep were the most important goals. Emollients, topical corticosteroids and antihistamines were the most frequently used treatments, while a minority of patients were prescribed potent medications, such as systemic immunosuppressants and gabapentinoids. Most patients were not satisfied with their previous therapy (56.8%), while 9.8% did not receive any therapy despite having active disease. A substantial number of respondents (28.7%) considered none of the therapeutic options effective. Although chronic nodular prurigo is a severe disease, most patients were not treated with potent systemic drugs, which may contribute to the high levels of dissatisfaction and disbelief in available therapies. Specific guidelines for chronic nodular prurigo and the development of novel therapies are necessary to improve care.

Prevalence of Itch in German Schoolchildren : A Population-based Study

Tidskriftsartikel (refereegranskat)abstract
- Itch is a common symptom, but there is limited evidence on the prevalence of itch in children. The aim of this study was to assess the prevalence of itch in schoolchildren. A questionnaire was developed by experts in the field and based on a literature search. The questionnaire was applied in a pilot study of 25 consecutively selected paediatric patients and their parents. It confirmed the high content validity of the questionnaire, and the questionnaire was comparable to hospital records regarding chronic itch (n = 19, mean consistency 89.47%). The questionnaire was distributed among German schoolchildren in 9/12 randomly selected primary schools in Kiel, Germany. Of 1,722 invited students, 443 schoolchildren aged 6-10 years participated, and 26.2% (n = 116) reported itch. The prevalence of acute itch was 20.0% (n = 87), and 14.7% (n = 65) reported chronic itch. Reduced sleep and mood were often related to chronic itch. This study demonstrated that itch is a common symptom in German schoolchildren.

- Skin pain is a common and bothersome symptom of atopic dermatitis (AD) that is associated with a substantial burden. To assess the efficacy of abrocitinib vs. dupilumab on skin pain in patients with moderate-to-severe AD. Data from patients aged ≥18 years who received oral abrocitinib 200 mg once daily (QD) or subcutaneous dupilumab 300 mg once every 2 weeks in combination with topical therapy in the phase 3 trials JADE COMPARE (NCT03720470) and JADE DARE (NCT04345367) were analysed. Data from patients who received abrocitinib 100 mg QD or placebo in the JADE COMPARE trial were also included in this analysis. Patients rated their skin pain using the Skin Pain Numerical Rating Scale (NRS) item of the Pruritus and Symptoms Assessment for Atopic Dermatitis (PSAAD) instrument [‘How painful was your skin over the past 24 h?’ on a scale from 0 (not painful) to 10 (extremely painful) ] in JADE COMPARE or the Skin Pain Numerical Rating Scale [SP-NRS, which queried patients for the severity of their ‘worst skin pain’ in the past 24 h on a scale from 0 (no skin pain) to 10 (worst skin pain imaginable)] in JADE DARE. Least squares mean (LSM) changes from baseline and proportions of patients who achieved a ≥4-point improvement from baseline in PSAAD skin pain score or SP-NRS were assessed through Week 16 (JADE COMPARE) or Week 26 (JADE DARE). The JADE COMPARE analysis (Skin Pain NRS item of the PSAAD) was performed post hoc, whereas the JADE DARE analysis (SP-NRS) was prespecified. At Week 2 of JADE COMPARE, LSM change from baseline in PSAAD skin pain score was greater with abrocitinib 200 mg [−2.8 (95% CI, −3.1, −2.5)] than with abrocitinib 100 mg [−2.1 (−2.3, −1.8)], dupilumab [−2.0 (−2.3, −1.8)], or placebo [−1.3 (−1.6, −0,9)]; improvements were sustained through Week 16 of treatment with abrocitinib 200 mg [−4.1 (−4.4, −3.8)], abrocitinib 100 mg [−3.3 (−3.6, −3.0)] and dupilumab [−4.0 (−4.2, −3.7)] compared with placebo [−1.8 (−2.2, −1.4)]. In JADE DARE, LSM change from baseline in SP-NRS was significantly greater with abrocitinib 200 mg vs. dupilumab at Week 2 [−3.7 (−3.9, −3.4) vs. −2.6 (−2.8, −2.3); P < 0.0001] and week 12 [−4.5 (−4.7, −4.2) vs. −4.0 (−4.3, −3.8); P = 0.0116]; no significant differences were observed between the treatment arms at Week 16 [−4.4 (−4.7, −4.2) vs. −4.2 (−4.4, −4.0); P = 0.16], Week 20 [−4.8 (−5.0, −4.5) vs. −4.5 (−4.7 vs. −4.2); P = 0.06] or Week 26 [−4.5 (−4.8, −4.3)] vs. −4.3 (−4.6, −4.1); P = 0.27]. The proportions of patients who achieved a ≥4-point improvement in PSAAD skin pain score at week 2 of JADE COMPARE were greater with abrocitinib 200 mg (43%) than with abrocitinib 100 mg (23%), dupilumab (24%) or placebo (14%). At Week 16, these proportions increased to 76% (abrocitinib 200 mg), 57% (abrocitinib 100 mg) and 70% (dupilumab) compared with placebo (29%). In JADE DARE, the proportions of patients who achieved a ≥4-point improvement in SP-NRS were significantly greater with abrocitinib 200 mg vs. dupilumab at Week 2 (58% vs. 36%; P < 0.0001) and Week 12 (71% vs. 61%; P = 0.0098) but not at subsequent timepoints. Similar to previous findings on the effect of abrocitinib on itch, these results suggest that abrocitinib 200 mg provides greater early skin pain relief in patients with moderate-to-severe AD compared with dupilumab, but the difference between the treatments diminishes with time. At earlier time points, skin pain improvement with abrocitinib 100 mg was similar to that with dupilumab.
