We report here two cases of vitiligo vulgaris successfully treated with the combination therapy of topical steroid and vitamin D3 compound and currently maintained by vitamin D3 analog without any adverse effects: skin atrophy, striae or telangiectasia on the exposed areas. The best-known mechanism of topical vitamin D3 analog is the enhancement of keratinocytes differentiation and anti-proliferative effects. Vitamin D3 analog is also reported to suppress T-cell mediated immunity, T-cell skin recruitment, and skin infiltration via down-regulating cutaneous lymphocyte antigen expression. Furthermore, vitamin D3 compounds are known to influence melanocyte maturation and differentiation and also to up-regulate melanogenesis. Autoreactive lymphocytes against melanocytes are one of the causes. Topical vitamin D3 analog may control vitiligo itself, however stronger immunosuppressive effects of topical corticosteroid may contribute to rapid re-pigmentation suppressing auto-reactive lymphocytes. The topical combination therapy is a simple, effective and safe option for vitiligo vulgaris in sun-exposed areas.

Background: Skin aging is inevitable. Wrinkles, skin texture abnormalities, senile hyperpigmentation, loss of skin tone, dryness, atrophy, and telangiectasias represent some of the hallmarks of aged skin. Skin rejuvenation can be addressed by topical therapies, such as topical retinoids and antioxidants or physical modalities with energy-based devices, all providing acceptable outcomes.

Drug-resistant epilepsy in pediatric patients is associated with neuroinflammation and neurodegeneration. Vitamin D 25-OH exerts neuroprotective effects, while glial cell line- derived neurotrophic factor (GDNF) and the proinflammatory cytokine interleukin-1β (IL-1β) are implicated in the mechanisms of neuroinflammation and epileptogenesis. The aim of this study was to investigate the relationship between vitamin D 25-OH, IL-1β, and GDNF levels with seizure severity and frequency in children with drug-resistant epilepsy.

Rationale: Smoking has been shown to be associated with circulating deficiencies in 25(OH)D3 and reduced sinonasal tissue levels of the active form of vitamin D, 1,25(OH)2D3. Given vitamin D's ability to reduce inflammation, we sought to examine if intranasal (IN) delivery of calcitriol [clinical analog of 1,25(OH)2D3] could reduce inflammation and improve disease severity in a murine model of chronic cigarette smoke-induced sinonasal inflammation (CS-SI).
Methods: Mice were exposed to CS 5 h/day, 5 days/week for 9 months, and then began IN calcitriol three times per week for 4 weeks.

Background: Vitamin D is the focus of extensive medical research globally. Recent studies have investigated the correlation between serum 25-hydroxyvitamin D (25(OH)D) and common inflammatory markers. However, few studies have incorporated novel inflammatory markers such as the platelet-to-lymphocyte ratio (PLR), platelet-to-high density lipoprotein cholesterol ratio (PHR), systemic inflammatory index (SII), neutrophil-to-lymphocyte ratio (NLR), systemic inflammatory response (SIRI), and neutrophil-to-high-density lipoprotein cholesterol ratio (NHR).
