Atopic dermatitis (AD) is a chronic inflammatory skin disease that is difficult to treat. Traditional cold cream, a water-in-oil emulsion made from beeswax, is used to alleviate AD symptoms in clinical practice, although its effectiveness has not been scientifically proven. The addition of propolis has the potential to impart anti-inflammatory properties to cold cream. However, in high concentrations, propolis can trigger allergic reactions. Thus, the objective of this work was to develop a cold cream formulation based on purified beeswax containing the same amount of green propolis present in raw beeswax. The impact of adding this low propolis concentration to cold cream on AD control was evaluated in patients compared to cold cream without added propolis (CBlank). Raw beeswax was chemically characterized to define the propolis concentration added to the propolis-loaded cold cream (CPropolis). The creams were characterized as to their physicochemical, mechanical, and rheological characteristics. The effect of CPropolis and CBlank on the quality of life, disease severity, and skin hydration of patients with AD was evaluated in a triple-blind randomized preclinical study. Concentrations of 34 to 120 ng/mL of green propolis extract reduced TNF-α levels in LPS-stimulated macrophage culture. The addition of propolis to cold cream did not change the cream’s rheological, mechanical, or bioadhesive properties. The preclinical study suggested that both creams improved the patient’s quality of life. Furthermore, the use of CPropolis decreased the disease severity compared to CBlank.

Abstract Background Anaemia is one of the most common extraintestinal manifestations in patients with inflammatory bowel disease(IBD) at diagnosis. Studies have shown that anaemia was associated with low levels of quality of life, which improves with the correction of anaemia in adults. Recent data have shown an increase in the incidence and severity of paediatric IBD. We aim to investigate the trends in the prevalence of anaemia in children at diagnosis of IBD in the last decade. The secondary aim was to investigate the associations between haemoglobin (Hb) levels and disease characteristics. Methods Eligible patients (age ≤18 years, diagnosed with IBD from 2009 to 2018) were retrospectively identified through a prospective IBD database maintained at CHU Sainte-Justine, Montreal, Canada. Disease localisation and phenotype were defined according to the Paris Classification of IBD. Anaemia was defined by Hb levels according to WHO targets. The annual prevalence of anaemia was calculated according to subtype (inflammatory vs. iron deficiency). The Pediatric Crohn’s Disease Activity Index(PCDAI) and the Pediatric ulcerative colitis Activity(PUCAI) Index were used to assess the disease severity at diagnosis. Results We included 887 patients (439 females), mean(SD) age of 13.1 (3.4) years. Of these, 519 (58.5%) were identified with anaemia within 30 days of diagnosis. The median (IQR) Hb level at diagnosis was 108 (98 −114) g/dl. Severe anaemia(< 70 g/dl) was present in 1.8 % of patients. The prevalence of anaemia at diagnosis remained relatively stable ranging from 60.2% in 2009 to 60.4% in 2018. The annual proportion of inflammatory vs. iron-deficiency anaemia is displayed in Figure 1. Anaemia was more prevalent in CD (62.2%) than UC (57.9%) or IBD-U(39.6%). The median(IQR) PCDAI and PUCAI were respectively 37.5 (27.5–47.5) and 55.0 (40.0–65.0) in the anaemic group as compared with 27.5 (20.0–37.50) and 35.0 (25.0–55.0) in the non-anaemic group; p < 0.0001. Patients with anaemia had a lower BMI z-score [median(IQR) −0.84(−1.84–0.08)] than the non-anaemic patients[median(IQR) −0.38(−1.21–0.43)]; p < 0.001. The prevalence of anaemia correlated significantly with disease location: upper intestinal involvement [L4a(67.7%) L4b(63.6%) L4aL4b(60.7%) none (52.8%)] p = 0.024 for CD; for UC[E1(21.1%) E2(44.4%) E3(75.0%) E4 (71.1%)] p < 0.0001. A moderate correlation was found between Hb levels and C-reactive protein (r = −0.312, 95% CI: −0.378 to −0.243, p < 0.0001). Conclusion Anaemia remains a prevalent symptom in paediatric patients with IBD, and it is correlated with the extent of intestinal involvement and disease severity. The impact of anaemia at diagnosis and during follow-up on the levels of quality of life and physical activity is currently under investigation.

Background and Objective Previous large studies have highlighted the impact of psoriasis on health-related quality of life (HRQoL) but not on interpersonal touch. This survey assessed the prevalence of touch avoidance among psoriasis patients, and its relationship to clinical characteristics and HRQoL. Methods Using an online, cross-sectional study with a standardized questionnaire, psoriasis patients reported their level of touch avoidance. The relationships between touch avoidance, patient-reported outcome measures, and patient demographics were analyzed using linear models for continuous outcomes and logistic models for categorical outcomes. Results Touch avoidance was reported by 48.2% of participants. Higher levels of touch avoidance were associated with worse HRQoL, depression, and itch outcomes (p<.001 for all). The strongest indicators of touch avoidance were HRQoL score (p<.001) and depression score (p<.001). Conclusion Nearly half of psoriasis patients report avoidance of touch. Those who had worse disease severity, HRQoL, and depression reported higher levels of touch avoidance.
