Glucocorticoid penetration was determined using Franz diffusion cells, quantifying metabolite concentrations by HPLC. Chemical stability and reactivity of the monoesters was determined by molecular modeling analysis.
Topical corticosteroids are frequently used in the treatment of irritant contact dermatitis (ICD). The efficacy of this treatment has, however, not been thoroughly established, and experimental studies on the topic have provided conflicting results. The aim of the present study was to evaluate the effect of potent topical corticosteroids on experimentally-induced irritant skin reactions in a double-blind, vehicle-controlled study. 16 healthy volunteers had sodium lauryl sulfate patch tests symmetrically applied to the upper arms. After removal of patch tests, a potent topical corticosteroid (betamethasone-17-valerate) was applied to the irritant skin reaction on one arm, while the corresponding vehicle was applied to the irritant skin reaction on the opposite arm 2x daily for 7 days. Reactions were evaluated by measurement of transepidermal water loss (TEWL) and erythema. After 7 days, statistically significant lower values of TEWL and erythema were found in corticosteroid-treated, compared to the vehicle-treated, skin reactions. The results indicate that topical corticosteroids improve healing of ICD.

Of the 55 patients, 19 (34.5%) underwent conventional circumcision, and 36 (65.5%) were treated with an 8-week course of topical steroid cream. The mean age was 3.9 years (range 0.6-10). Grade 1, 2, 3, 4, and 5 phimosis was seen in 1 (2.8%), 4 (11.1%), 8 (22.2%), 16 (44.4%), and 7 (19.4%) of the cases in the topical steroid cream group, respectively. The success rate for the topical steroid cream was 69.4% and 63.9% at 3 and 8.3 months, respectively. The objectivation of the phimosis grade did not predict the outcome (P > .05). No side effects were associated with the topical steroid treatment.

Mucous membrane pemphigoid is a heterogeneous group of autoimmune, subepithelial, blistering diseases. A combination of topical and systemic steroid treatment is often used when managing patients with mucous membrane pemphigoid. The use of systemic steroids presents an increased risk of adverse side effects. Consequently, effective alternative modalities of therapy should be considered, such as the application of low-level laser therapy (LLLT).

Calcipotriol, a vitamin D3 analog, acts not only to inhibit cell proliferation and enhance cell differentiation in the skin of patients with psoriasis, but also appears to have effects on immunologic markers that are thought to play a role in the etiology of the disease. In several well designed, short term studies in adults, calcipotriol ointment 50 micrograms/g twice daily provided similar or superior efficacy to several other antipsoriatic agents in adult patients with mild to moderate psoriasis. In patients with nonscalp psoriasis, the drug provided superior efficacy to twice daily placebo (vehicle ointment), twice daily fluocinonide 500 micrograms/g, once daily tacalcitol 4 micrograms/g and twice daily coal tar 5% plus allantoin 2% and hydrocortisone 0.5%. Furthermore, calcipotriol therapy generally provided superior efficacy to twice daily betamethasone valerate 1 to 1.2 mg/g or once daily dithranol 1 to 20 mg/g, and similar efficacy to twice daily betamethasone dipropionate plus salicylic acid or once daily maxacalcitol 6 to 50 micrograms/g. Limited data indicated that calcipotriol ointment 50 micrograms/g also improved overall disease severity in children. In combination with other antipsoriatic agents [acitretin, cyclosporine, betamethasone valerate, halobetasol (ulobetasol)], ultraviolet B or psoralen ultraviolet A (PUVA) phototherapy, calcipotriol ointment 50 micrograms/g twice daily improved the beneficial effects of these drugs on overall disease severity in adult patients with moderate to severe psoriasis. Furthermore, in separate trials, calcipotriol combination therapy reduced the dosage of acitretin required to achieve clearance of psoriasis and the duration of PUVA and dosage of UVA phototherapy, potentially improving the benefit/risk ratio for these other antipsoriatic treatments. Calcipotriol was generally well tolerated in short and long term studies in adult patients, with the majority of adverse events being mild to moderate in intensity and transient. The most common adverse events associated with calcipotriol therapy were dermatologic in nature and included lesional or perilesional irritations, face and scalp irritations, worsening of psoriasis and miscellaneous dermatologic events. Notably, there have been very few reports of patients developing hypercalcemia or hypercalciuria during calcipotriol therapy, with most occurring in patients who exceeded the recommended dosage of 100 g/week. Although data in children are limited, the drug was well tolerated with the nature and incidence of adverse effects similar to those observed in adult patients.

Nerve fibers penetrate into the epidermis 24h after acetone treatment in mice, and nerve growth peaks 48h after acetone treatment. To investigate the effects of UV-based therapies on the epidermal nerve fibers, including combination treatment with corticosteroid ointment, the mice were treated with psoralen ultraviolet A (PUVA), PUVA and betamethasone valerate ointment (PUVA+BV), narrowband ultraviolet B (NB-UVB), or an excimer lamp. Each therapy was provided 24h after acetone treatment, and skin samples were taken 48h later. Nerve fiber densities and expression levels of nerve growth factor (NGF) and semaphorin 3A (Sema3A) in the epidermis were examined by immunohistochemistry.
In vitropermeation experiments of BM-17-V were carried out in Franz diffusion cells using isolated human SC and ASC. Permeation data from both systems were compared statistically and those data were linearly correlated to each other. The saturation concentrations of BM-17-V within the formulations were calculated based on microscopical examination. The BM-17-V was metabolized via BM-21-V into betamethasone (BM) as its hydrolization product during the permeation experiments across SC. Since ASC has a higher enzymatic activity and less barrier qualities than SC, furthering the course of the permeation experiment, not only BM permeates besides the noncatabolized drug BM-17-V, but also 9alpha-fluoro-prednisolone as another decomposition product. The detection of BM-17-V and its degradation product was performed by high-performance liquid chromatography.

A screening method based on liquid chromatography-electrospray mass spectrometry for the simultaneous determination of six corticosteroids (betamethasone 17-valerate BM 17-V, beclomethasone BC, beclomethasone dipropionate BCDP, methylprednisolone MP, budesonide BD, flunisolide FN) was developed in order to control their illegal use in cosmetic and natural products. Indeed, despite corticosteroids are banned in cosmetics, counterfeit products might be present on the market, representing a health hazard. Therefore, effective analytical methods are required to rapidly screen over the counter products in health care shops for counterfeit corticosteroids. The analytical method involves the employment of a Waters Synergy C18 column (150mm×2.0mm I.D.) by using the following mobile phase: A (0.1% formic acid in acetonitrile), B (0.1% formic acid in water) in a linear gradient (from A-B 25:75, v/v to A-B 95:5, v/v in 30min) at the flow rate of 0.3mL/min. The detection was performed with an ion trap (IT) mass spectrometer in positive polarity, total ion current (TIC) and tandem mass modalities for qualitative purpose; single ion monitoring (SIM) mode was used for quantitative analysis on the ESI generated most abundant ion for each steroid. The method was fully validated in terms of precision, detection and quantification limits, linearity, recovery, and it was applied to the identification and quantification of corticosteroids in pharmaceutical formulations and cosmetic products. The mean recovery of BM 17-V, BC, BCDP, MP, BD and FN were found to be 101.3, 101.5, 98.8, 98.9, 98.1, 99.0%, respectively. Limits of quantitation (LOQ) were comprised in the range 29-95ng/mL. To the best of our knowledge, for the first time this mix of glucocorticoids were simultaneously determined in cosmetic products by using a fully validated method. BMV, in its two isomeric forms BM 17-V and BM 21-V, was found to be illegally present in one cream sample (A) with the total concentration level of 0.036% (w/w).
Progressive pigmented purpura (Schamberg's disease), a form of purpura pigmentosa chronica, is a lymphocytic capillaritis of unknown etiology and obscure pathogenesis. Our purpose was to assess the expression of cell membrane antigens (CD3, CD4, CD1a, CD36), of adhesion receptors (leukocyte function adhesion 1, LFA-1, endothelial leukocyte adhesion molecule 1, ELAM-1) intercellular adhesion molecule 1, ICAM-1), and the intercellular relationships in the early phase of the disease.
