Abstract
OBJECTIVES The aim of this study was to develop fluticasone propionate (FP)-loaded solid lipid nanoparticle (SLN) formulations by using factorial design approach. MATERIALS AND METHODS Tristearin percentages (X1) (1%, 2%, and 4%) and homogenization cycles (X2) (2, 4, and 8 cycles) were selected as independent variables in the factorial design. SLN formulations were optimized by multiple linear regression (MLR) to evaluate the influence of the selected process and formulation independent variables on SLNs' characteristics, namely as encapsulation efficiency (Q1) and particle size (Q2). The polydispersity index and surface charge of the SLNs were also evaluated in this research. Moreover, transmission electron microscopy, differential scanning calorimetry, and in vitro drug release studies were carried out on the optimum SLN formulation. RESULTS The MLR analysis indicated that as the homogenization cycle (X2) increased in the production process, the mean particle size decreased. CONCLUSION This research showed that FP-encapsulated SLNs with desired characteristics can be produced by varying the production and content variables of the formulations.

Abstract
BACKGROUND Use of a continuous glucose-monitoring system (CGMS) in the management of type 1 diabetes (T1D) may cause local skin irritation. OBJECTIVE To examine the effects of fluticasone propionate aqueous nasal solution (nsFP), sprayed topically prior to CGMS insertion among youth with T1D. METHODS This is a case series observational report, including real-life 6-month follow-up data from one pediatric diabetes center. All patients suffering from local skin irritation due to CGMS adhesives were offered prevention form skin irritation by spraying 2 puffs of nsFP on the skin area prior to adhesion of CGMS. Data were collected from their charts after 6 months. Outcome measures included the difference in degree of skin irritation, number of days of CGMS use, BMI SDS, mean glucose, and HbA1c, prior to use and during 6 months after use. RESULTS Twelve patients used nsFP prior to CGMS insertion, mean age 8.6 ± 4.9 years and 66.7% males. Ten patients, median age 6.1 years (5.3-9.5) and 56% males, continued using nsFP for a mean of 0.56 ± 0.11 years, with no recurrence of local irritation nor dermatitis to same adhesive material. No differences were found before and after use of nsFP in CGMS mean glucose 180 mg/dl (153-202) versus 165 mg/dl (150-192). BMI SDS was slightly higher 0.44 (- 0.9-1.2) versus 0.25 (- 0.47-1.06), P = 0.05. CONCLUSIONS This small-scale, single-site description of a simple intervention by nsFP and favorable outcome provides valuable insight for a simple solution for skin irritation and dermatitis in the pediatric population with T1D.

Eosinophilic esophagitis (EoE) genetic susceptibility is mediated by synergistic interactions between EoE-specific and general atopic disease loci. J Allergy Clin Immunol 2017; 141:1690-1698. [PMID: 29129581 DOI: 10.1016/j.jaci.2017.09.046] [Citation(s) in RCA: 40] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2017] [Revised: 08/26/2017] [Accepted: 09/27/2017] [Indexed: 01/07/2023]
Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is an esophageal inflammatory disease associated with atopic diseases. Thymic stromal lymphopoietin (TSLP) and calpain 14 (CAPN14) genetic variations contribute to EoE, but how this relates to atopy is unclear. OBJECTIVE The purpose of this study was to explore the relationship between EoE, atopy, and genetic risk. METHODS EoE-atopy enrichment was tested by using 700 patients with EoE and 801 community control subjects. Probing 372 single nucleotide polymorphisms (SNPs) in 63 atopy genes, we evaluated EoE associations using 412 nonatopic and 868 atopic disease control subjects. Interaction and stratified analyses of EoE-specific and atopy-related SNPs were performed. RESULTS Atopic disease was enriched in patients with EoE (P < .0001). Comparing patients with EoE and nonatopic control subjects, EoE associated strongly with IL-4/kinesin family member 3A (IL4/KIF3A) (P = 2.8 × 10-6; odds ratio [OR], 1.87), moderately with TSLP (P = 1.5 × 10-4; OR, 1.43), and nominally with CAPN14 (P = .029; OR, 1.35). Comparing patients with EoE with atopic disease control subjects, EoE associated strongly with ST2 (P = 3.5 × 10-6; OR, 1.77) and nominally with IL4/KIF3A (P = .019; OR, 1.25); TSLP's association persisted (P = 4.7 × 10-5; OR, 1.37), and CAPN14's association strengthened (P = .0001; OR, 1.71). Notably, there was gene-gene interaction between TSLP and IL4 SNPs (P = .0074). Children with risk alleles for both genes were at higher risk for EoE (P = 2.0 × 10-10; OR, 3.67). CONCLUSIONS EoE genetic susceptibility is mediated by EoE-specific and general atopic disease loci, which can have synergistic effects. These results might aid in identifying potential therapeutics and predicting EoE susceptibility.

Abstract
Treatment of children diagnosed with atopic dermatitis (AD) is an art. Age-dependent barrier function, skin physiology, body surface:weight ratio, the compliance of patient and caregivers, and legal considerations related to the license status of topical and systemic drugs must be considered. Mild to moderate AD can usually be treated sufficiently with a personalized regimen of emollients and topical anti-inflammatory therapy consisting of topical corticosteroids (TCSs) or topical calcineurin inhibitors. Emollients containing bacterial lysates, tailored wet wrap regimen, and proactive therapy with tacrolimus ointment or some TCSs are new developments in the field. Severe AD may need systemic therapy, but all currently available systemic agents for severe AD are either not licensed for children or not advisable on the long term, or both. Therapeutic patient education based on structured, interactive sessions with patients or caregivers and a multidisciplinary team is highly effective. This publication summarizes the current therapeutic options used in the pediatric AD population.

Abstract
Although emollients are recommended in the management of atopic dermatitis (AD), regimens for emollient maintenance therapy are awaiting validation. We conducted an international, multicenter, open-label trial to assess the effects of a 3-month maintenance treatment regimen with a sterile, preservative-free emollient cream containing oat plantlets in children (ages 6 mos-6 yrs) with moderate AD. After a 14-day run-in stabilization phase using a topical corticosteroid (TCS) treatment of medium potency, 108 children with a SCORing Atopic Dermatitis (SCORAD) index of 20 or less were included in the study. Emollient was applied twice daily for 3 months. Rescue TCS treatment was used only in cases of flare-ups. The SCORAD index, Patient-Oriented SCORAD (PO-SCORAD) index, number of flares, TCS use, and tolerance were assessed at months 1, 2, and 3 (M1, M2, M3). AD severity improved, with a highly significant decrease in the SCORAD and PO-SCORAD indexes at M2 and M3 (p < 0.001). Changes from baseline to M3 were 48.6 ± 73.6% for SCORAD and 29.6 ± 125.3% for PO-SCORAD. The number of flares and TCS use significantly decreased by M3 (both p < 0.001). Very good tolerance was recorded in 100% of children at M2 and M3. Notwithstanding the limitations inherent in open-label trials, twice daily application of the oat-based sterile emollient cream led to a significant improvement of clinical symptoms, evidenced by parallel changes in the SCORAD and PO-SCORAD indexes and fewer flare-ups. Clinical benefit and less TCS use were maintained at M3. Tolerance was very good.
