Hyperimmunoglobulin E syndrome(HIES) is a primary immunodeficiency characterized by severe recurrent soft-tissue infections, pneumonias, pruritic dermatitis and markedly elevated serum IgE levels. Pneumatocele and empyema develop as result of recurrent pneumonias. It is inherited in an autosomal dominant fashion, with variable expressivity. We experienced the case of a 10 month old girl with hyper IgE syndrome. Patient was admitted for local ulceration and muscle soreness at the site of BCG inoculation. The diagnosis of hyper IgE syndrome was made because she had a coarse facial appearance, pruritic dermatitis, pneumatocele and markedly elevated serum IgE level with a past history of frequent skin abscess and pneumonia.

Objectives: Realgar has been frequently used for skin disorders in history of herbal medicine. However, the efficacy of realgar has not been examined in atopic dermatitis(AD). In this study, the effects of realgar on AD were investigated, especially on pruritus and inflammation. Methods: AD lesions were induced in the shaved backs of BALB/c mice through repeated application of DNCB. The mice were treated for 11 days with 1% realgar ($100{\mu}L/day$). Histological changes in skin thickness were observed. The anti-pruritic effects of realgar were evaluated by the change in numbers of scratching behavior of mice and expression of substance P. The expressions of cytokines IL-4 and IL-6 were measured. Also, anti-inflammatory effects of realgar were examined on expressions of NF-${\kappa}B$, phospho-$I{\kappa}B{\alpha}$ and mitogen-activated protein kinases (MAPKs). Results: Realgar decreased skin thickness (both dermal and epidermal) 38% and 17% respectively, compared to positive control, DNCB group. The scratching behavior of mice was reduced by 42% and expression of substance P was significantly less. Cytokines IL-4 and IL-6 were significantly reduced by 52.6% and 77.6%, respectively. The expressions of NF-${\kappa}B$, phospho-$I{\kappa}B{\alpha}$ and MAPKs (phospho-ERK1/2, -p38 and -JNK) were significantly suppressed with marked effects on phospho-ERK1/2. Conclusions: The collective results suggest that realgar shows anti-pruritic and anti-inflammatory effects on AD. And realgar might be a potential therapeutic candidate for treatment of atopic dermatitis.

Objectives : This study investigated the anti-oxidant activities and improving effect of Phellinus linteus and Glycyrrhiza uralensis Extract (PGE) on Atopic Dermatitis. Methods : 2,2′-diphenyl-1-picrylhydrazyl (DPPH) radical, 2,2′-azino-bis 3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical, Hydrogen peroxides scavenging activities and Superoxide dismutase (SOD)-like activities were used for the measurement of anti-oxidant ability. Cytotoxicity of PGE in Raw 264.7 cell was evaluated by MTT assay. To evaluate the anti-atopic dermatitis effect of PGE, a total of 33 patients with atopic dermatitis were observed trans epidermal water loss, skin moisture content, modified SCORAD index of atopic dermatitis and pruritic degree after applying the PGE for 4 weeks. Results : PGE scavenged DPPH ($IC_{50}=25ppm$) effectively, ABTS and Hydrogenperoxides scavenged similar to BHA. As for the SOD-like activity, it had lower effect than ascorbic acid, but it comparable activities in 500ppm. There was no cytotoxicity at PGE at concentrations of 10,000ppm. In clinical research about PGE on patients with atopic dermatitis, skin condition was improved. After 4 weeks, the application of PGE increased skin moisture content from 19.43 to 31.22. Moreover, it reduced the skin temperature (from 32.5 to 31.9), skin pH (from 5.39 to 5.22), trans epidermal water loss (from 39.03 to 24.46) and pruritus score (from 6.07 to 3.87). In addition, the Modified SCORAD index decreased from 31.28 to 20.3. Conclusions : In conclusion, PGE possesses anti-oxidant and anti-atopic dermatitis activities, thus it could be potentially valuable as anti-atopic dermatitis material.

Atopic dermatitis is characterized by chronically pruritic and inflammatory dermatitis. In this study, we investigated the effect of Platycodon grandiflorum including platycodin D (PG-Platycodin D) in an atopic dermatitis-like mouse model. An atopic dermatitis-like skin lesion was induced by repeated treatment of 2,4-dinitrochlorobenzene (DNCB) on the dorsal skin of ICR mice. The efficacy of PG-Platycodin D was tested by observing scratching behavior, the skin severity score, and histopathologic analysis. PG-Platycodin D reduced the DNCB-induced increase in scratching behavior and the skin severity score. In addition, histopathologic analysis revealed a reduction in the thickening of the epidermis in the PG-Platycodin D group. These results may contribute to the development of a therapeutic drug for the treatment of atopic dermatitis.

Objectives: Poncirus trifoliata Rafinesque has been known to have anti-allergic effects in skin diseases. However, anti-atopic dermatitis effects of P. trifoliata Rafinesque have not been studied yet in skin diseases. The present study evaluated the anti-atopic dermatitis effects of P. trifoliata Rafinesque (PTR) using external treatments on AD. Methods: AD lesions were induced by the repeated application of 2, 4-Dinitrochlorobenzene (DNCB) on the shaved back of BALB/c mice. $100{\mu}{\ell}$ of PTR extracts was applied to the AD lesions for 11 days. Histological assessments, mast cells count and serum levels of IgE were analyzed. The anti-pruritic effects of PTR were examined by the change of scratching frequency and nerve growth factor (NGF) expression. In addition, the anti-inflammatory effects of PTR were examined by the expressions of Th2/Th1 cytokines and pro-inflammatory in dorsal skin. Results: Histopathological findings showed that topical application of PTR decreased the thickness of dermal and epidermal skin compared with the DNCB group. PTR also notably decreased the mast cells count and serum IgE. The scratching behavior of mice and expression of NGF were significantly reduced. In addition, PTR group significantly suppressed the IL-4, IL-6, IFN-${\gamma}$ and TNF-${\alpha}$ cytokines compared to the DNCB group. Conclusions: These results indicated that P. trifoliata Rafinesque possess anti-pruritus and anti-atopic dermatitis properties. Therefore, P. trifoliata Rafinesque might be used for treatment of pruritus and atopic dermatitis.

Canine atopic dermatitis (CAD) is a genetically predisposed inflammatory and pruritic skin disease presenting characteristic clinical features in dogs. Despite oclacitinib and lokivetmab being commonly used, no study has compared their efficacies in CAD. This study aimed to compare the efficacy, safety, and control of CAD-associated pruritus and skin lesions between oclacitinib and lokivetmab. It also investigated whether switching to lokivetmab from oclacitinib or prednisolone had any benefits. Twenty-five client-owned dogs, newly diagnosed with CAD, were allocated to the oclacitinib (n = 20) and lokivetmab (n = 5) groups and administered oclacitinib (0.4-0.6 mg/kg orally, twice daily for 14 days, then once daily) and lokivetmab (2 mg/kg subcutaneously, every month) for 8 weeks, respectively. The switching group included five dogs previously administered with oclacitinib (n = 4) or prednisolone (n = 1) who were switched to lokivetmab directly at the start of the study. The pruritus visual analog scale (PVAS) and Canine Atopic Dermatitis Extent and Severity Index (CADESI-04) values were surveyed at weeks 0, 4, and 8. Oclacitinib and lokivetmab significantly reduced the PVAS and CADESI-04 scores. Switching from oclacitinib or prednisolone to lokivetmab maintained the severity of pruritus (4 weeks: p = 0.068; 8 weeks: p = 0.068) and dermatitis (4 weeks: p = 0.144; 8 weeks: p = 0.068) at the levels measured at baseline. Thus, both oclacitinib and lokivetmab reduced CAD-associated pruritus by a similar degree. Switching to lokivetmab maintained the severity of pruritus and dermatitis at the same level as the previous treatment.

Canine atopic dermatitis (CAD) is an inflammatory and pruritic skin disease with a genetic predisposition, characterized by allergic sensitivity. It is known for its distinctive clinical features, including a high recurrence rate and chronic progression. To manage CAD, medications such as steroids and immunosuppressants are commonly used, but consideration should be given to the potential resistance and side effects associated with long-term use. In order to reduce these risks, various adjunctive factors are currently under consideration. One of these adjunctive agents, probiotics have shown effectiveness in regulating atopic dermatitis by modulating immune responses, as demonstrated in several recent studies. In this study, a substance combining three probiotics-L. plantarum, L. reuteri, and Ped. Acidilactici-was used in patients diagnosed with CAD, and its clinical effects and safety were evaluated. The trial involved four groups: a group receiving conventional treatment for atopic dermatitis (A), a group prescribed low-dose probiotics (B), a group prescribed high-dose probiotics (C), and a group prescribed topical probiotics (D). For assessment, the Canine Atopic Dermatitis Extent and Severity Index (CADESI), Trans-Epidermal Water Loss (TEWL) test, gut microbiome, and serum IgE test were conducted. As a result, the CAD severity index (CADESI-4) significantly decreased in the probiotics groups (B & C). In the serum total IgE test, the groups consuming probiotics showed a significant difference, while the group using topical probiotics (D) did not exhibit a significant change. Also, the TEWL test showed improved scores in the probiotics groups (B & C). Therefore, L. plantarum, L. reuteri, and Ped. Acidilactici probiotic combination could be considered as an effective adjunctive treatment, especially for atopic patients with moderate to severe skin lesions.
