Timing of complementary feeding for early childhood allergy prevention: An overview of systematic reviews.
OBJECTIVE: To summarise and critically appraise systematic review (SR) evidence on the effects of timing of complementary feeding (CF) on the occurrence of allergic sensitisation and disease. DESIGN: Overview of SRs. AMSTAR-2 and ROBIS were used to assess methodological quality and risk of bias (RoB) of SRs. RoB 2 Tool was used to assess RoB of primary randomised controlled trials (RCTs) (or extracted). The certainty of evidence (CoE) was assessed using GRADE. Findings were synthesised narratively. DATA SOURCES: MEDLINE (via PubMed and Ovid), the Cochrane Library and Web of Science Core Collection (2010 to 27 February 2023). ELIGIBILITY CRITERIA: SRs investigating the effects of timing of CF in infants or young children (0-3âyears) on risk of developing food allergy (FA), allergic sensitisation, asthma, allergic rhinitis, atopic eczema and adverse events based on RCT evidence. RESULTS: Eleven SRs were included. Only two SRs had low RoB; common issues were failure to report on funding of primary studies and failure to provide a list of excluded trials. Common limitations of included trials were lack of blinding of outcome assessment or detailed trial preregistration, and inadequate handling of high loss to follow up. Primary study overlap was very high for specific FA and slight to moderate for FA in general and other primary outcomes. Introducing specific foods (peanut, cooked egg) early probably reduces the risk of specific FA. Evidence for other allergic outcomes was mostly very uncertain and based on few primary studies. Trials varied regarding timing of CF, nature of complementary foods and population risk, which limited comparability between SRs. CONCLUSIONS: For developing guidelines to support decision-making on the timing of CF as a preventive strategy, early introduction of specific foods (i.e. egg and peanut) seems promising and safe, whereas more extensive research is required regarding other allergic outcomes and potential adverse events

Targeting the Neurokinin Receptor 1 with Aprepitant: A Novel Antipruritic Strategy
Chronic pruritus is a global clinical problem with a high impact on the quality of life and lack of specific therapies. It is an excruciating and frequent symptom of e.g. uncurable renal, liver and skin diseases which often does not respond to conventional treatment with e.g. antihistamines. Therefore antipruritic therapies which target physiological mechanisms of pruritus need to be developed. Substance P (SP) is a major mediator of pruritus. As it binds to the neurokinin receptor 1 (NKR1), we evaluated if the application of a NKR1 antagonist would significantly decrease chronic pruritus.Twenty hitherto untreatable patients with chronic pruritus (12 female, 8 male; mean age, 66.7 years) were treated with the NKR1 antagonist aprepitant 80 mg for one week. 16 of 20 patients (80%) experienced a considerable reduction of itch intensity, as assessed by the visual analog scale (VAS, range 0 to 10). Considering all patients, the mean value of pruritus intensity was significantly reduced from 8.4 VAS points (SD +/-1.7) before treatment to 4.9 VAS points (SD +/-3.2) (p<0.001, CI 1.913-5.187). Patients with dermatological diseases (e.g. atopic diathesis, prurigo nodularis) had the best profit from the treatment. Side-effects were mild (nausea, vertigo, and drowsiness) and only occurred in three patients.The high response rate in patients with therapy refractory pruritus suggests that the NKR1 antagonist aprepitant may indeed exhibit antipruritic effects and may present a novel, effective treatment strategy based on pathophysiology of chronic pruritus. The results are promising enough to warrant confirming the efficacy of NKR1 antagonists in a randomized, controlled clinical trial

Entwicklung eines deutschsprachigen Fragebogens zur Erfassung von chronischem Pruritus (AGP-Fragebogen). Hintergrund und erste Ergebnisse.
Chronic pruritus may manifest itself clinically in terms of different duration, intensity and quality. There is no questionnaire assessing these parameters systematically. The study presents a pruritus questionnaire for the German speaking region (AGP-Questionnaire) developed by 4 experts in the field. It comprises questions on course, intensity and quality of pruritus, general health status, sociodemographic data, quality of life (QoL) and pruritus cognition. Standardised questionnaires such as the SF-12 Health Survey (recall period 4 weeks), the Hospital Anxiety and Depression Scale (HADS) and the Dermatology Life Quality Index (DLQI) were also used to assess the instrument's convergent validity. Feedback of the participants was obtained by a one-page evaluation sheet. 100 patients suffering from chronic pruritus of the university hospitals of Giessen, Heidelberg, Munich and Muenster participated in the study. This questionnaire is useful in providing a comprehensive and structured approach to assessing individual patients' chronic pruritus. The validity and sensitivity of this new pruritus questionnaire will require examination in further studies
