Itching is a frequent condition at a doctor's appointment of any speciality. A quarter of patients complain of itching of various etiology. In real practice, H1-histamine receptor blockers are prescribed for itching in the first place. The article considers a complex of diseases accompanied by itching of the skin. The itching is a reflex. The classification contains a lot of forms:local and systemic; prurigogenic, neuropathic and psychogenic. Itching has no stable pathogenesis and can be provoked by various conditions. The main types of sensory neurons are opiate and 5-HT-receptors. Urticaria and food allergy are associated with irritation of the skin receptors with histamine and other mast cell mediators. In these cases, antihistamines are the drug of choice regardless of the aetiology of urticaria. In atopic dermatitis, the itching has a complex aetiology: transepidermal water loss, chronic inflammation of the skin with the participation of many cells, secondary hyperinervation of the skin with the formation of a pathological activity focus in the brain. This requires a comprehensive approach to therapy. Xerosisis overcome by the use of emollients and rational skincare. The presence of exacerbation makes it necessary to prescribe topical steroids or calcineurin inhibitors for an acute period s. In the case of the addition of psychogenic itching, antiserotonin 5-HT-blockers drugs, hydroxyzine can be considered. H1-receptor blockers do not affect the intensity of skin lesions in dermatitis, but some molecules can reduce the itching. Quifenadine is the antihistamine dug of the second generation. It can be used in the treatment of allergic itching dermatoses. The rapid onset of action allows you to reach the maximum concentration in the tissues within 1 hour, activate monooxidase and neutralise histamine in the tissue. Quifenadine absence a sedative effect and no respiratory depression.Instructions for the use of the medicinal product can increase the dose by 1,5–2 times.It makes the drug useful for the treatment of manifestations of food allergies and urticaria. The dual antihistamine and antiserotonin action allow the successful use of quifenadine in the acute period of atopic dermatitis, especially provoked by contact with an allergen.

Plants of the genus Wikstroemia have long been used as traditional medicines to treat diseases like pneumonia, rheumatism, and bronchitis. This study was designed to determine the effect of chamaejasmine, a biflavonoid present in W. dolichantha, on atopic dermatitis (AD)-like skin lesions in a 2,4-dinitrochlorobenzene (DNCB)-induced murine model of AD. Initially, we examined the anti-allergic activities of ten flavonoids from W. dolichantha by measuring β-hexosaminidase release from RBL-2H3 cells. Subsequently, an SKH-1 hairless mouse model of AD was developed based on the topical application of DNCB. Chamaejasmine (0.5%) or pimecrolimus (1%, positive control) were applied to dorsal skins of DNCB-sensitized AD mice for two weeks. Serum IL-4 and IgE levels were determined using enzyme-linked immunosorbent assay kits and transepidermal water loss (TEWL) and skin hydration were measured using a Tewameter TM210 and a SKIN-O-MAT, respectively. Of the ten flavonoids isolated from W. dolichantha, chamaejasmine most potently inhibited DNP-specific IgE-induced degranulation in RBL-2H3 cells. Topical administration of chamaejasmine attenuated the clinical symptoms of DNCB-induced dermatitis (i.e., itching, dryness, erythema, and edema). Histological analyses demonstrated that dermal thickness and mast cell infiltration in dermis were significantly reduced by chamaejasmine. In addition, 0.5% chamaejasmine inhibited DNCB-induced increases in total IL-4 and IgE levels in serum, improved skin barrier function, and increased epidermis moisture. Our findings suggest chamaejasmine might be an effective therapeutic agent for the treatment of atopic diseases.

Atopic dermatitis (AD) is a chronic inflammatory disease. Combretum quadrangulare (C. quadrangulare) is used as a traditional medicine to improve various pathologies in Southeast Asia. In this study, we investigated the effects of C. quadrangulare ethanol extract (CQ) on 1-chloro-2,4-dinitrobenzene (DNCB)-induced AD like skin lesions in BALB/c mice. After administration with CQ (100, 200, and 400 mg/kg) for 6 weeks, AD symptoms, protein expression, immunoglobulin E (IgE), thymus and activation-regulated chemokine (TARC), and ceramidase level were measured in skin lesions of DNCB-induced BALB/c mice. CQ group improved the dermatitis score, skin pH, transepidermal water loss (TEWL), and skin hydration. Furthermore, histological analysis revealed that CQ attenuated the increased epidermal thickness and infiltration of mast cells caused by DNCB. CQ also increased the expression of filaggrin, and reduced the expression of ceramidase, serum IgE level, and the number of eosinophils. CQ effectively inhibited cytokines and chemokines such as interleukin (IL)-6, IL-13, TARC, and thymic stromal lymphopoietin (TSLP) at the mRNA levels, as well as the activation of mitogen-activated protein kinase (MAPK), including extracellular signal-regulated kinase (ERK), c-jun N-terminal kinase (JNK), and p38 in the skin lesions. Taken together, these findings demonstrate that CQ may be an effective treatment of AD-like skin lesions by inhibiting the expression of inflammatory mediators via the MAPK signaling pathways.

Atopic dermatitis (AD) is a chronic inflammatory skin disease which has a complex etiology that encompasses immunologic responses. The study was carried out to examine the effect ofNelumbo nucifera(Gaertn.) leaf (NL) on the AD-like skin lesion induced by repeated epicutaneous application of 2,4-dinitrochlorobenzene (DNCB) on the dorsal skin of NC/Nga mice. Three different doses of NL (5, 25, and 50 mg/mice/day) were administered orally from the day of sensitization with DNCB for 4 weeks. The efficacy of NL was judged by histopathological examination, blood IgE level, measurement of transepidermal water loss (TEWL), scratching behavior, and skin severity score. NL resulted in the suppression of clinical severity score, TEWL, scratching behavior, and blood IgE level. Histopathologic analyses revealed that thickening of the epidermis and mast cell degranulation was significantly reduced in NL group. These results suggest that NL may be a useful natural resource for the management of AD.

Background. Structural and functional damages of the epidermal barrier in patients with atopic dermatitis promote the entry of allergens and development of Th2-type allergic inflammation. Moisturizers containing lipids increase the physiological antiinflammatory effects of topical corticosteroids (TGKS), improve the epidermal barrier and reduce the duration of TGKS using preventing further infringement barrier. To evaluate the clinical efficacy of emollient milk Xemose in children with atopic dermatitis. Materials and methods. We examined 27 children with atopic dermatitis. Children were divided into 2 groups: patients in group 1 (n=14) used emollient milk Xemose twice a day on the skin lesions and limbs in the complex therapy, patients in the 2nd group (n=13) received combined therapy incorporating traditional dampening agents on the basis of lanolin (Unna cream) 3 times daily. All patients underwent measurement of transepidermal water loss (TEWl) (Tewameter TM 300, Multi Probe Adapter MPA 5/9, Courage + Khazaka) and the pH of the skin (Skin-pH-Meter, Multi Probe Adapter MPA 5/9, Courage + Khazaka) before and after 2 weeks of therapy. Results. Patients in groupthat used Xemose milk and children in group with Unna cream after 2 weeks showed a statistically significant decrease of TEWl (p=0,041 and p=0,04, respectively). TEWl was significantly lower in children treated for 2 weeks with milk Xemose (p=0,027) than in children treated with Unna cream. in both groups pH skin surface have not changed (р=0,22 and р=0,22 respectively). Conclusion. Clinical efficacy of milk Xemose as compound improving skin barrier function in children with atopic dermatitis was shown.

Abstract Stellera chamaejasme, also known as “Langdu”, has been traditionally used for the management of skin-related diseases such as psoriasis and skin ulcers. The aim of this study was to determine whether S. chamaejasme and its major component, luteolin 7-O-glucoside, have a preventive effect on the development of atopic dermatitis in oxazolone-treated BALB/c mice and 2,4-dinitrochlorobenzene-treated hairless mice. The epicutaneous applications of oxazolone and 2,4-dinitrochlorobenzene evoke an experimental murine atopic dermatitis-like reaction in BALB/c mouse ears and SKH-1 hairless mice. Atopic skin symptoms, including erythema (redness), pruritus (itching), exudation (weeping), excoriation (peeling), and lichenification (skin thickening), responded to treatment with S. chamaejasme aerial parts EtOH extract for 2 or 3 weeks. Histopathological examination revealed S. chamaejasme aerial parts EtOH extract significantly reduced inflammatory cell infiltration when applied to atopic dermatitis mice. In addition, luteolin 7-O-glucoside, the major active compound of the S. chamaejasme aerial parts EtOH extract, decreased serum IgE and IL-4 levels and transepidermal water loss and increased skin hydration, therefore exhibiting strong anti-atopic dermatitis activity in 2,4-dinitrochlorobenzene-induced atopic dermatitis mice. In this study, we confirmed antipruritic and antidermatitic effects of S. chamaejasme extract and its main component luteolin 7-O-glucoside in atopic dermatitis murine models. The study shows S. chamaejasme aerial parts EtOH extract and luteolin 7-O-glucoside are most likely to be potential drug candidates for atopic dermatitis treatment.

Lichen planus pigmentosus inversus (LPPI) is a rare subvariant of Lichen planus pigmentosus (LPP), presenting with sharply defined brown to gray macules, papules, and plaques limited to the intertriginous areas, with only a few cases reported in the medical literature so far. While LPP mostly affects patients with Fitzpatrick skin type III–IV in sun-exposed areas such as the neck, LPPI is seen in Caucasians and spares sun-exposed areas. Skin lesions tend to be very refractory to treatment attempts including potent topical steroids and oral corticosteroids. Given the increased penetration of potent topical steroids and the high risk of skin atrophy, especially when applied to intertriginous areas, this case shows that topical calcineurin inhibitors (tacrolimus 0.1%) might offer an effective and safe treatment option for LPPI.

Plants of the genus Wikstroemia are traditionally used to treat inflammatory diseases like bronchitis and rheumatoid arthritis. In the present study, the anti-atopic effects of an EtOH extract of Wikstroemia dolichantha (WDE) on oxazolone- and DNCB (2,4-dinitrochlorobenzene)-induced dermatitis in mice were investigated. Both ears of BALB/c mice were exposed to oxazolone, and dorsal skins of SKH-1 hairless mice were sensitized with DNCB to induce acute eczematous atopic skin lesions. 1% WDE was applied daily to oxazolone- and DNCB-induced AD mice for two or three weeks, respectively. Total IL-4 and IgE concentrations in serum, transepidermal water loss (TEWL) and skin hydration were assessed. High-performance liquid chromatography/mass spectrometry (HPLC/MS) was used to determine the composition of WDE. Dermal application of 1% WDE grossly and histopathologically improved oxazolone- and DNCB-induced AD skin symptoms. Epidermal thickness and mast cell infiltration were significantly lower in animals treated with WDE than in vehicle controls. Furthermore, in addition to reducing DNCB-induced increases in serum IL-4 (interleukin 4) and IgE (immunoglobulin E) levels, WDE also decreased TEWL and increased skin hydration (indicative of improved skin barrier function). The four flavonoids taxifolin, aromadendrin, padmatin and chamaejasmine were tentatively identified in WDE by HPLC-DAD/QTOF-MS. The above results show WDE protected against oxazolone- and DNCB-induced AD in mice by down-regulating the TH2-associated cytokine IL-4 and improving skin barrier function and suggest WDE might be useful for the management of atopic dermatitis.
