Curcumin Ameliorates Ovalbumin-Induced Atopic Dermatitis and Blocks the Progression of Atopic March in Mice

AbstractCurcumin, extracted from the roots ofCurcuma longa, has been used as an anti-inflammatory agent since the time of Ayurveda. The present work was designed to evaluate the potential of curcumin in amelioration of ovalbumin (OVA) induced AD in mice. Female BALB/c mice were subjected to skin OVA-patch application for a period of 1 week followed by resting period of 2 weeks, and the same protocol was repeated thrice. Curcumin was administered daily at dose of 20 mg/kg (i.p.) for 7 consecutive days during last sensitization phase. The phytochemical ameliorated the OVA-induced skin pathology as evident by normalization of epidermal thickness and suppressed infiltration of inflammatory cells in dermal region. The expression of Th2 promoting cytokines (TSLP/IL-33) and Th2 cytokines (IL-4/IL-5/IL-13/IL-31) was suppressed markedly along with reduced STAT-6 phosphorylation and GATA-3 expression. Curcumin administration also restored the redox balance and phosphorylation status of P65-NF- κB. Additionally, the epicutaneously sensitized mice challenged with aerosolized OVA developed asthmatic features which were effectively thwarted back upon curcumin treatment as reflected by data on total/differential cells in BALF and mRNA expression of Th2 cytokines in lungs. Overall, our finding s demonstrate that curcumin treatment blunts the development of AD as well as associated atopic march in experimental mice.

Purpose of review To present and discuss key design concepts for optimizing the impact of observational studies in the field of allergy and to highlight recent findings from NIAID-funded research networks. Recent findings We discuss three concepts. First, the benefit of prospective, longitudinal observational studies exemplified by recent findings on the seasonal nature of all rhinitis phenotypes in children with asthma and the protective effects of high house dust allergen content during the first year of life on the development of asthma at age 7 years. Second, the benefit of detailed (deep) phenotyping exemplified ...

CONCLUSIONS: In adults with severe chronic rhinosinusitis and nasal polyps, using regular topical nasal steroids, dupilumab improves disease-specific HRQL compared to placebo, and reduces the extent of the disease as measured on a CT scan. It probably also improves symptoms and generic HRQL and there is no evidence of an increased risk of serious adverse events. It may reduce the need for further surgery. There may be little or no difference in the risk of nasopharyngitis. In similar patients, mepolizumab may improve both disease-specific and generic HRQL. It is uncertain whether it reduces the need for...

Conclusion: FHRs to seafish in AD patients are associated with persistent eczematic lesions and with the higher occurrence of sensitization to fungi and reactions to celery. The occurrence of bronchial asthma, rhinitis, positive family history, and onset of AD under 5 years of age is higher in patients with reactions to seafish, but the difference is not statistically significant.

ák Igaz Réh During production, thermally modified wood is processed using the same machining operations as unmodified wood. Machining wood is always accompanied with the creation of dust particles. The smaller they become, the more hazardous they are. Employees are exposed to a greater health hazard when machining thermally modified wood because a considerable amount of fine dust is produced under the same processing conditions than in the case of unmodified wood. The International Agency for Research on Cancer (IARC) states that wood dust causes cancer of the nasal cavity and paranasal sinuses and...

This study aimed to determine serum total IgE level, eosinophil count, and serum level of IFN-γ, in relation to the age of atopic patients and genotyping of the IFN-γ gene at +874 T/A in relation to serum IFN-γ level. As well as comparing of IFN-γ concentrations of atopic patients according to genotypes in atopic patients and apparently healthy control. The studied groups were 25 apparently healthy controls and 75 atopic patients (25 asthma patients, 25 allergic rhinitis patients and 25 atopic dermatitis patients). The obtained results showed that, the prevalence of atopic diseases occurred in the...

CohenBackgroundEvidence of TH1/IFN-γ overactivation as a major pathogenic driver somewhat conflicts with data supporting robust allergic background in patients with alopecia areata (AA). Previous investigations of immunological dysregulations show that both TH1- and TH2-related markers are overexpressed in AA. Clinical correlations in large populations may shed light on the immune pathways most likely to result in the clinical p...

Authors: Ingawale DK, Mandlik SK Abstract Inflammation is a physiological intrinsic host response to injury meant for removal of noxious stimuli and maintenance of homeostasis. It is a defensive body mechanism that involves immune cells, blood vessels and molecular mediators of inflammation. Glucocorticoids (GCs) are steroidal hormones responsible for regulation of homeostatic and metabolic functions of body. Synthetic GCs are the most useful anti-inflammatory drugs used for the treatment of chronic inflammatory diseases such as asthma, chronic obstructive pulmonary disease (COPD), allergies, multiple sclerosis, te...
