Objective: To compare the efficacy and safety of topical nicotinamide for the treatment of mild to moderate psoriasis in Interventional Clinical Trial study compared with calcipotriol-betamethasone. Patients and methods: Our study was carried out on sixty patients from November 2019 to March 2020, complaining of psoriasis thirty patients treated by topical nicotinamide 4% weekly and thirty patients treated by topical calcipotriol-betamethasone weekly. Patients were selected from out-patient clinic of Dermatology, Venereology and Andrology Department of Al-Azhar University Hospitals. Results: The present study using topical nicotinamide 4% weekly versus calcipotriol –betamethasone weekly showed lesions on both sides were similar regarding baseline Psoriasis Area and Severity Index (PASI) score (P = 0.148), while at 1 month and 3 months after therapy, PASI scores were significantly lower with calcipotriol betamethasone in the second group as compared with nicotinamide alone in first group (P < 0.001). At the end of the trial, PASI scores were reduced by 17.9± 7.8 points before treatment to 12.2± 5.08 after 12 weeks with nicotinamide as compared to 16.2 ± 5.5 before treatment to 9.1± 3.2 points with calcipotriol betamethasone (P < 0.001). Conclusion: Nicotinamide can be used for topical psoriasis treatment and may be a good adjuvant to be added to the treatment regimens of psoriasis and it was less effective than calcipotriol betamethasone regarding clinical response and patient's satisfaction. Keywords: Nicotinamide 4%, Calcipotriol-betamethasone, Psoriasis.

Scott Litofsky * Division of Neurosurgery, University of Missouri School of Medicine, Columbia, MO 65212, USA; [email protected] * Correspondence: [email protected] Abstract: Survival in glioblastoma remains poor despite advancements in standard-of-care treatment. Some patients wish to take a more active role in their cancer treatment by adopting daily lifestyle changes to improve their quality of life or overall survival. We review the available literature through PubMed and Google Scholar to identify laboratory animal studies, human studies, and ongoing clinical trials. We discuss which health habits patients adopt and which have the most promise in glioblastoma. While results of clinical trials available on these topics are limited, dietary restrictions, exercise, use of supplements and cannabis, and smoking cessation all show some benefit in the comprehensive treatment of glioblastoma. Marital status also has an impact on survival. Further clinical trials combining standard treatments with lifestyle modifications are necessary to quantify their survival advantages.

Vitamin D and immunomodulation in the skin: a useful affirmative nexus. Explor Immunol. 2021;1:90-111. https://doi.org/10.37349/ei.2021.00009 Abstract Skin is the largest organ of the body having multifunctional activities. It has a dynamic cellular network with unique immunologic properties to maintain defensive actions, photoprotection, immune response, inflammation, tolerogenic capacity, wound healing, etc. The immune cells of the skin exhibit distinct properties. They can synthesize active vitamin D [1,24(OH)2D3] and express vitamin D receptors. Any difficulties in the cutaneous immune system cause skin diseases (psoriasis, vitiligo, atopic dermatitis, skin carcinoma, and others). Vitamin D is an essential factor, exhibits immunomodulatory effects by regulating dendritic cells’ maturation, lymphocytes’ functions, and cytokine production. More specifically, vitamin D acts as an immune balancing agent, inhibits the exaggeration of immunostimulation. This vitamin suppresses T-helper 1 and T-helper 17 cell formation decreases inflammatory cytokines release and promotes the maturation of regulatory T cells and interleukin 10 secretion. The deficiency of this vitamin promotes the occurrence of immunoreactive disorders. Administration of vitamin D or its analogs is the therapeutic choice for the treatment of several skin diseases.

  • Calcipotriol/Betamethasone (Dovobet®) in Psoriasis
    Bulletin 90 | March 2015 Community Interest Company Calcipotriol/betamethasone (Dovobet®) in psoriasis This bulletin focuses on calcipotriol/betamethasone (Dovobet®) for the treatment of psoriasis. The annual spend on Dovobet® across England is £28.7 million (ePACT October - December 2014). QIPP projects in this area are aimed at reviewing the appropriate use and duration of treatment of Dovobet®. A 50% reduction in prescribing through stopping prolonged treatment could result in potential annual savings of £9 million across England (ePACT October - December 2014). Support materials (briefing, aide-memoire, data collection and patient letter) are available at: http://www.prescqipp.info/resources/viewcategory/326-dovobet-in-psoriasis Recommendations • Vitamin D analogue monotherapy (calcipotriol, calcitriol, tacalcitol) or corticosteroid therapy are first line treatments for the majority of patients with chronic plaque psoriasis.1 Calcitriol ointment is the least expensive vitamin D analogue based on cost per gram. Calcipotriol ointment is the least expensive vitamin D analogue preparation if calculated using the maximum daily application over a four week period (see tables 1 and 2). • Dovobet® is a vitamin D analogue and steroid combination product which should only be considered for poor responders.1 • Dovobet® is recommended as a 4th line treatment for trunk and limb psoriasis in adults but not children or adolescents.1 • Dovobet® gel is recommended as a 3rd line treatment for scalp psoriasis in adults and children or adolescents. Use in children is unlicensed and initiation should be restricted to secondary care.1 • Dovobet® should not be used for the face, flexures or genitals in adults or children.1 • Dovobet® should only be used once daily and for a maximum duration of 4 weeks1 and should only be prescribed as acute treatment.

Batch specific analytical results are provided on each certificate of analysis. Laboratory Procedures Calcipotriol (hydrate) is supplied as a crystalline solid. A stock solution may be made by dissolving the calcipotriol (hydrate) in an organic solvent purged with an inert gas. Calcipotriol (hydrate) is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide. The solubility of calcipotriol (hydrate) in these solvents is approximately 50 mg/ml. Calcipotriol (hydrate) is sparingly soluble in aqueous buffers. For maximum solubility in aqueous buffers, Calcipotriol (hydrate) should first be dissolved in ethanol and then diluted with the aqueous buffer of choice. Calcipotriol (hydrate) has a solubility of approximately 0.15 mg/ml in a 1:5 solution of ethanol:PBS (pH 7.2) using this method. We do not recommend storing the aqueous solution for more than one day. Description Calcipotriol (hydrate) is a low-calcemic vitamin D receptor (VDR) agonist. Calcipotriol (hydrate) is about 1 200 times less potent in its effects on calcium metabolism than vitamin D (1,25[OH]D3). Binding of calcipotriol (hydrate) to the VDR increases AP-1, a transcription factor important for keratinocyte differentiation, and reduces expression of JunB protein, a transcriptional activator in the inflammatory response.2 Calcipotriol (hydrate) also induces expression of thymic stromal lymphopoietin, which triggers T cell differentiation in keratinocytes.3 References 1.

Here we review pathophysiology of vitamin D with particular reference to COVID-19 and pancreatic cancer. Utility as a therapeutic agent is limited by hypercalcemic effects and attempts to circumvent this problem have used vitamin D superagonists, with increased efficacy and reduced calcemic effect. A further caveat is that vitamin D mediates multiple diverse effects.
