Meta-Analysis
BACKGROUND
Intranasal corticosteroid (INCS) has a beneficial effect on ocular symptoms in allergic rhinitis (AR). To our knowledge, the cost-effectiveness of available INCS for AR with ocular symptoms is yet to be demonstrated.
OBJECTIVE
To evaluate the cost-effectiveness of INCSs including Budesonide (BANS), Mometasone furoate (MFNS), Triamcinolone (TANS), and Fluticasone furoate (FFNS) on ocular symptoms associated with AR in the Thai context.
METHODS
The percentage of effectiveness in improving total ocular symptoms score (TOSS) was derived from the result of a meta-analysis that estimated the SMD of each INCS treatment compared to placebo as clinical input parameters. A cost-effectiveness analysis based on a decision-tree model to assess one-year costs and outcomes from a Thai societal perspective. The outcomes were to compare incremental cost-effectiveness ratio (ICER). Probabilistic sensitivity analyses (PSA) were also conducted to capture parameter uncertainties.
RESULTS
13 eligible RCTs with a total of 3,722 patients with SAR were included in the analysis. The percentage of effectiveness of FFNS, MFNS, TANS, and BANS was 59.89%, 45.60%, 24.89%, and 16.00%, respectively. The ICER of FFNS, MFNS, and TANS is THB-6,539.92, 4,593.83, and 1,401.24 compared to BANS. CECA result showed the probability of using FFNS is considered cost-effective in 87.50% of cases from zero value followed by MFNS (0.80%), TANS (5.40%), and BANS (6.30%). With a threshold greater than THB20,000, FFNS is considered a cost-effective strategy.
CONCLUSIONS
FFNS is a cost-effective option compared to alternative INCSs in Thailand for treating AR with ocular symptoms.

BACKGROUND
Interleukin 17 (IL-17) and interferon gamma (IFN-γ) play a role in the pathogenesis of psoriasis vulgaris (PV). Topical corticosteroids are still utilised as first-line therapy for mild to moderate PV. However, long-term use of corticosteroid is associated with various side effects. Linn. (Ciplukan) possesses anti-inflammatory properties that could serve as a potential alternative topical therapy for PV.
OBJECTIVE
To assess the efficacy of topical ciplukan as an anti-inflammatory agent targeting the expression of IL-17 and IFN-γ.
METHODS
Psoriasis was induced using imiquimod cream, therefore divided into five groups. Group I, the psoriasis control group, received only imiquimod cream. Groups C1 and C2 received imiquimod cream followed by a mixture of Ciplukan and vaseline in a 1:2 and 1:4 ratio, respectively. Group M, the standard therapy group, received imiquimod cream, followed by mometasone furoate cream. Lastly, group V, the vehicle group, received imiquimod cream followed by vaseline album. Expression of IL-17 and IFN-γ in mice's skin tissue was analysed using reverse transcription polymerase chain reaction (RT-PCR) after seven days of treatment.
RESULTS
The mean expression of IL-17 in Group C1 (22.60) was significantly lower (p = 0.012) than in the psoriasis control group (23.60), and there was no significant difference (p = 0.613) in Group M (22.41). The mean expression of IFN-γ in Group C1 (26.97) and Group C2 (27.03) was also significantly lower (p = 0.026 and p = 0.026, respectively) than Group I (28.80), and there was no significant difference (p = 0.180 and p = 0.093, respectively) than Group M (26.03).
CONCLUSION
Expression of IL-17 and IFN-γ in the ciplukan group is lower than in the psoriasis control group, and there is no significant difference compared to the standard therapy group.

PURPOSE
We designed a 0.05% mometasone furoate (MF) nanocrystal dispersion and investigated whether the application of MF nanocrystals in nasal formulations enhanced local absorption compared to traditional nasal MF formulations (CA-MF).
METHODS
MF nanocrystal dispersions (MF-NPs) were prepared by bead milling MF microcrystal dispersions (MF-MPs) consisting of MF, 2-hydroxypropyl-β-cyclodextrin, methylcellulose, and purified water. Pluronic F-127 combined with methylcellulose, Pluronic F-68, or carbopol was used as a base for in situ gelation (thickener). MF concentrations were measured using high-performance liquid chromatography, and nasal absorption of MF was evaluated in 6 week-old male Institute of Cancer Research (ICR) mice.
RESULTS
The particle size range of MF prepared with the bead mill treatment was 80-200 nm, and the nanoparticles increased the local absorption of MF, which was higher than that of CA-MF and MF-MPs. In addition, unlike the results obtained in the small intestine and corneal tissue, the high absorption of nanocrystalline MF in the nasal mucosa was related to a pathway that was not derived from energy-dependent endocytosis. Moreover, the application of the in situ gelling system attenuated the local absorption of MF-NPs, owing to a decrease in drug diffusion in the dispersions.
CONCLUSION
We found that nanoparticulation of MF enhances local intranasal absorption, and nasal bioavailability is higher than that of CA-MF. In addition, we demonstrate that viscosity regulation is an important factor in the design of nasal formulations based on MF nanocrystals. These findings provide insights for the design of novel nanomedicines with enhanced nasal bioavailability.

: Limited data exists on the use of rivaroxaban for the treatment of pediatric patients. This report presents a case of probable rivaroxaban-induced Erythema Multiforme in Children. A female patient aged 5.5 years with antiphospholipid syndrome (APS) was administered oral rivaroxaban tablets 2.5 mg twice a day for 16 days. Subsequently, the patient developed a slight itching sensation on both feet and buttocks without an apparent cause. The following day, erythema multiforme appeared across the body in a scattered pattern. The erythema presented higher than the skin surface and partially merged into areas of the skin. Following an increase in the extent and degree of the erythema, all oral medications were ceased. Treatment with dexamethasone sodium phosphate injection, mometasone furoate cream, and mucopolysaccharide polysulfate cream resulted in an improvement of erythema multiforme. The erythema diminished and did not deteriorate subsequent to changing from rivaroxaban tablets to warfarin sodium tablets, and receiving nadroparin calcium injection.

ETHNOPHARMACOLOGICAL RELEVANCE
Mahuang-Lianqiao-Chixiaodou decoction (MLCD) is a traditional Chinese medicinal (TCM) formula recorded in the Treatise on Febrile Diseases. It is commonly used for clinical treatment of atopic dermatitis (AD). However, the potential mechanisms of MLCD intervention in AD combined with mental disorders behaviors such as anxiety and depression remain elusive and deserves further investigation.
AIM OF THE STUDY
The study aims to observe the effect of MLCD on anxiety- and depression-like behaviors in AD mice and explore the possible neuroinflammatory mechanism of NOD-like receptor 3 (NLRP3) inflammasome.
MATERIALS AND METHODS
The chemical components of MLCD extracts were identified using UHPLC-MS. The AD mice were induced by 2,4-dinitrofluorobenzene and treated with MLCD or mometasone furoate (MF, as a positive control) for 7 days. The pathological changes in their skin tissue and brain hippocampus were observed by hematoxylin-eosin staining. Elevated plus-maze test (EPM), open field test (OFT), and the suspended tail (TST) were used to measure the anxiety- and depressive-like behaviors in AD mice. Expression of NLRP3 inflammasome-related proteins in brain hippocampus were measured by the quantitative real-time polymerase chain reaction (qPCR) and western blotting (WB).
RESULTS
We found that MLCD contain many active ingredients, including ephedrine, Forsythoside A, phillyrin, glycyrrhizic acid, etc. Both MLCD and MF alleviated skin lesions and promoted positive histopathological changes in the hippocampus of AD mince to varying degrees. MLCD however, could further increase their proportion of open arm entry times (Oentries%) in EPM, residence time in the central area (Ctime) and the proportion of the number of times in the central area (Centries%) in OFT significantly. MLCD also reduces their immobility time in TST considerably. Mechanistically, MLCD downregulated the relative mRNA expression and protein level of NLRP3, Caspase-1, IL-1β, and IL-18 in hippocampal tissue compared to the model group.
CONCLUSIONS
MLCD can alleviate anxiety-like and depression-like behaviors in AD mice by intervening in the gene and protein expression of NLRP3 inflammasome-related factors, thus treating AD.

OBJECTIVES
The primary objective is to describe a case in which a steroid-eluting implant was utilized to help prevent postoperative granulation and restenosis in a patient who underwent double-stage laryngotracheal reconstruction (dsLTR) for subglottic stenosis.
METHODS
This case presents a 3-year-old female who underwent dsLTR with anterior cartilage graft placement and posterior sagittal split for subglottic stenosis. A silicone stent was placed at the time of the dsLTR. After stent removal, direct laryngoscopy and bronchoscopy (DLB) was performed at 4 to 5 week intervals. These visits revealed a significant amount of supraglottic and glottic edema, and granulation tissue at the proximal aspect of the graft contributing to airway obstruction and restenosis. This was treated twice with CO laser excision, balloon dilation, and triamcinolone injection. On the third treatment with these modalities, a mometasone furoate implant was inserted as an adjunctive therapy. The implant was inserted to lateralize the vocal folds, prevent webbing, and to extend to the narrowed area within the subglottis to prevent granulation and restenosis. These same treatments were repeated at the fourth visit with another mometasone furoate implant of a smaller size placed in the same location.
RESULTS
Findings on DLB since treatment with the steroid-eluting implants have shown persistent granulation tissue limited to the tracheostomy stoma site. Treatments with CO laser, balloon dilation, and triamcinolone injection have continued, with occasional use of silver nitrate cautery at the external stoma site. There has not been any significant evidence of edema, granulation, or stenosis in the glottis or subglottis to require another steroid-eluting implant.
CONCLUSIONS
Steroid-eluting implants appear to be a safe and effective adjunctive therapy in the routine surveillance of pediatric patients with a tracheostomy who have undergone dsLTR. They may help combat granulation formation and restenosis seen in some dsLTR patients.

Randomized Controlled Trial
To assess bioequivalence of locally acting suspension-based nasal sprays, the U.S. FDA currently recommends a weight-of-evidence approach. In addition to in vitro and human pharmacokinetic (PK) studies, this includes a comparative clinical endpoint study to ensure equivalent bioavailability of the active pharmaceutical ingredient (API) at the site of action. The present study aimed to assess, within an in vitro/in vivo correlation paradigm, whether PK studies and dissolution kinetics are sensitive to differences in drug particle size for a locally acting suspension-based nasal spray product. Two investigational suspension-based nasal formulations of mometasone furoate (MF-I and MF-II; delivered dose: 180 μg) differed in API particle size and were compared in a single-center, double-blind, single-dose, randomized, two-way crossover PK study in 44 healthy subjects with oral charcoal block. Morphology-directed Raman spectroscopy yielded volume median diameters of 3.17 μm for MF-I and 5.50 μm for MF-II, and dissolution studies showed that MF-II had a slower dissolution profile than MF-I. The formulation with larger API particles (MF-II) showed a 45% smaller and 45% smaller AUC compared to those of MF-I. Systemic bioavailability of MF-I (2.20%) and MF-II (1.18%) correlated well with the dissolution kinetics, with the faster dissolving formulation yielding the higher bioavailability. This agreement between pharmacokinetics and dissolution kinetics cross-validated both methods and supported their use in assessing potential differences in slowly dissolving suspension-based nasal spray products.

Intranasal delivery is the most preferred route of drug administration for treatment of a range of nasal conditions including chronic rhinosinusitis (CRS), caused by an infection and inflammation of the nasal mucosa. However, localised delivery of lipophilic drugs for persistent nasal inflammation is a challenge especially with traditional topical nasal sprays. In this study, a composite thermoresponsive hydrogel is developed and tuned to obtain desired rheological and physiochemical properties suitable for intranasal administration of lipophilic drugs. The composite is comprised of drug-loaded porous silicon (pSi) particles embedded in a poloxamer 407 (P407) hydrogel matrix. Mometasone Furoate (MF), a lipophilic corticosteroid (log P of 4.11), is used as the drug, which is loaded onto pSi particles at a loading capacity of 28 wt%. The MF-loaded pSi particles (MF@pSi) are incorporated into the P407-based thermoresponsive hydrogel (HG) matrix to form the composite hydrogel (MF@pSi-HG) with a final drug content ranging between 0.1 wt% to 0.5 wt%. Rheomechanical studies indicate that the MF@pSi component exerts a minimal impact on gelation temperature or strength of the hydrogel host. The in-vitro release of the MF payload from MF@pSi-HG shows a pronounced increase in the amount of drug released over 8 h (4.5 to 21-fold) in comparison to controls consisting of pure MF incorporated in hydrogel (MF@HG), indicating an improvement in kinetic solubility of MF upon loading into pSi. Ex-vivo toxicity studies conducted on human nasal mucosal tissue show no adverse effect from exposure to either pure HG or the MF@pSi-HG formulation, even at the highest drug content of 0.5 wt%. Experiments on human nasal mucosal tissue show the MF@pSi-HG formulation deposits a quantity of MF into the tissues within 8 h that is >19 times greater than the MF@HG control (194 ± 7 μg of MF/g of tissue vs. <10 μg of MF/g of tissue, respectively).

Randomized Controlled Trial
This study aimed to investigate the efficacy and safety of vitamin D supplementation in the treatment of allergic rhinitis (AR) using mometasone. A total of 140 patients with moderate and severe AR treated at our hospital between January 2017 and August 2020 were recruited as subjects for this study. The patients were randomly divided into control and experimental groups, with 70 patients in each group. Mometasone nasal spray was used in both groups, and vitamin D was administered to the experimental group for four weeks. The total nasal symptom scores (TNSS) and rhinoconjunctivitis quality of life questionnaire (RQLQ) were used to assess the efficacy of treatment. T lymphocyte subsets (CD3+, CD4+ and CD8+) and serum anti-inflammatory and proinflammatory cytokines such as interleukin-10 (IL-10), tumor necrosis factor-α (TNF-α), and interferon-γ (IFN-γ) were analyzed. The incidence of adverse reactions was recorded. Serum vitamin D levels were lower in patients with AR. After 4 weeks of treatment, total TNSS scores, T lymphocyte subsets (CD3+, CD4+), CD4+/CD8+ ratio, TNF-α, and total RQLQ scores were significantly reduced compared to the initial testing (P<0.05) in the two groups; CD8+, IFN-γ, and IL-10 levels as well as serum vitamin D were significantly increased compared to the initial test (P<0.05). The improvement in these parameters in the experimental group was significantly greater than that in the control group (P<0.05), except for sneezing and eye symptoms in the TNSS and RQLQ scores. It was concluded that vitamin D supplementation improves the therapeutic effect of mometasone nasal spray on AR and is thus recommended as an adjuvant therapy for moderate and severe AR.

Journal of Cosmetic Dermatology Feb 2024Frontal fibrosing alopecia (FFA) is a cicatricial alopecia with rapid epidemic growth. However, there is no agreement on the best therapeutic approach. (Randomized Controlled Trial)
Randomized Controlled Trial
BACKGROUND
Frontal fibrosing alopecia (FFA) is a cicatricial alopecia with rapid epidemic growth. However, there is no agreement on the best therapeutic approach.
AIMS
To compare the therapeutic effects of finasteride as a first-line systemic treatment of FFA versus hydroxychloroquine as a relatively safe and effective immunosuppressive drug.
METHODS
Thirty-four female FFA patients were randomly assigned to receive either 400 mg/day of hydroxychloroquine or 2.5 mg/day of finasteride for 6 months. Topical treatments in both groups include pimecrolimus, mometasone, and minoxidil. Treatment efficacy was evaluated using the Frontal Fibrosing Alopecia Severity Score (FFASS), photography, and trichoscopy after 3 and 6 months.
RESULTS
Both the finasteride and hydroxychloroquine groups showed significant improvements in FFASS and trichoscopic scores (p < 0.01). However, there was no significant difference between the two groups during the study. Photographic assessment showed that more than 60% of patients in both groups had improved without statistically significant differences between the two groups.
CONCLUSIONS
Both finasteride and hydroxychloroquine are equally effective, safe, and well-tolerable for treating FFA patients.
