Janus kinases (JAKs) are non-receptor protein tyrosine kinases that are expressed in many tissues. Once the JAKs are activated, a cascade of further signaling events is triggered involving phosphorylation of selected receptor chain tyrosines, binding of signal transducer and activator of transcription (STAT) proteins and phosphorylation of these STATs. Due to their ability to selectively modulate immune function, targeted JAK inhibitors are promising candidates for some skin diseases such as psoriasis and atopic dermatitis...

Atopic Dermatitis (AD), a common skin disease, can occur in patients of all age, gender and ethnicity. It is an inflammatory affection, characterized by chronic and highly debilitating behavior. First-line interventions against AD include environmental measures and topical emollients, corticosteroids or calcineurin inhibitors. When these measures are not sufficient, phototherapy represents an efficient second-line option of treatment; it can be administered on its own, or in the most severe cases combined with systemic medicaments such as corticosteroids...

The exposure to ultraviolet radiations and visible light, or phototherapy, is a well-known therapeutic tool available for the treatment of many dermatological disorders. The continuos medical and technological progresses, of the last 50 years, have involved the field of phototherapy, which evolved from UVA and PUVA in its various forms, to the development of narrowband UVB (NB-UVB) and NB-UVB micro-focused phototherapies. Further advances in technology have now permitted the introduction of a new device emitting UVA-1 radiations...

Introduction: Recently, the monochromatic excimer light (MEL) of 308 nm wavelength has shown some advantages in comparison to narrow band ultraviolet B (NB-UVB) for the treatment of vitiligo. To histopathologically compare the early effects of NB-UVB and 308-nm MEL phototherapy on vitiliginous patches using H&E and HMB-45. Methods: Thirty subjects with non-segmental vitiligo lesions were treated twice a week for 6 weeks with 308-nm MEL, while NB-UVB was used to treat lesions contra laterally. Skin biopsies were taken from lesional areas before and after 6 weeks of treatment by either modality...

Photosensitive atopic dermatitis (AD) is a rare disease entity that many physicians are not familiar with, thus it often is misdiagnosed. It can be life altering, as patients often strictly avoid the sun and may only leave the house at night. Effective treatments are available, and therefore diagnosis is key to improve quality of life for these patients. We describe a case of photosensitive AD exacerbated by UVB exposure. The diagnosis was made with phototesting, and the patient was able to begin treatment with narrowband UVB (NB-UVB) hardening while on immunosuppression...

Psoriasis is one of the most common chronic, inflammatory, T-cell-mediated autoimmune diseases. Narrow-band UVB (NB-UVB) therapy is widely used in the treatment of psoriasis; however, its mechanism of action is still not well understood. The objective of this study was to investigate the circulating T-lymphocyte subpopulations in psoriasis patients before and after NB-UVB, to get insights into the mechanism of NB-UVB in the treatment of psoriasis. The severity of psoriasis was assessed by means of the Psoriasis Area and Severity Index (PASI-score)...

UV- based (PUVA and Narrow Band UVB) phototherapy is broadly and commonly used in the treatment of Cutaneous T-cell Lymphomas (CTCL), yet unfortunately the evidence for the efficacy of these treatments is based only on cases series or prospective but non-randomized studies. Therefore, no internationally approved guidelines exists and no standardization of schedules have been proposed. Recently, Consensus guidelines have been published by the United States Cutaneous Lymphoma Consortium. The aim of this paper is to review the biologic and clinical evidences on PUVA and NB UVB in CTCL, and to critically evaluate acceptability and feasibility of these guidelines in the real-life setting from the perspective of the Cutaneous Lymphoma Task Force of the Italian Lymphoma Foundation (Fondazione Italiana Linfomi, FIL)...

Vitiligo is a disorder characterized by the development of depigmented macules and patches. Existing treatments include topical and systemic immunosuppressants, topical vitamin D analogues in monotherapy or in association with phototherapy, phototherapy and surgical techniques, which together may serve to halt disease progression, stabilize depigmented lesions, and encourage repigmentation. Narrow-band UVB (NB-UVB 310-315 nm) radiation is now considered as the "gold standard" for the treatment of diffuse vitiligo...

Cutaneous lichen planus (CLP) is a chronic autoimmune disease classically associated with severely pruritic, polygonal, violaceous, flat-topped papules and plaques. Subtypes such as hypertrophic and bullous lichen planus and lichen planus pigmentosus have been described. Treatment can be challenging, and prospective controlled studies are lacking. Corticosteroids remain the major options for topical and systemic treatment, although some non-steroidal options exist. Phototherapy, especially with narrow band ultraviolet B (NB-UVB), is effective, but caution must be taken because of the risk of keobnerization...

Mycosis fungoides (MF), the most common variant among cutaneous T cell lymphomas (CTCL), is characterized in its early stages by clonal proliferation of malignant T-cells in the skin manifesting as erythematous patches and plaques with a chronic course and progression to cutaneous tumors and extracutaneous organs in some patients. Skin directed therapies (SDT) are primarily used for effective palliation in early stage disease. Phototherapy with ultraviolet A radiation combined with 8-methoxypsoralen (PUVA) and with ultraviolet B radiation (UVB) has a longstanding history in the treatment of MF and are highly effective in inducing remissions...

Interleukin (IL)-33 can function both as a conventional cytokine and as a nuclear factor regulating gene transcription. IL-33 expression is strongly upregulated in the nucleus of keratinocytes and serum of patients with psoriasis. However, the role of IL-33 in psoriasis is unclear, and IL-33 expression in the lesional psoriatic skin after conventional systemic treatments has not been investigated. In this study, we aimed to compare IL-33 mRNA in patients' lesional skin samples and IL-33 protein expression in patients' serum before and after treatment with methotrexate (MTX) and narrowband ultraviolet B (NB-UVB)...

BACKGROUND: Narrowband NB-UVB phototherapy (NB-UVB) is an effective treatment for psoriasis, as demonstrated by clinical trials. However, due to required infrastructure and need for treatment attendance opinions on the value of offering this treatment in routine practice vary. AIMS: To provide high quality large-scale and long-term data on the efficacy of NB-UVB for psoriasis under real-world conditions in order to assist in management decisions. METHODS: The following resources were employed: (1) complete and prospectively recorded prescription drug records for a population of 420,000 marked by low demographic mobility, (2) prospectively recorded clinical treatment outcomes for all NB-UVB treatment episodes occurring in the local population; (3) complete dermatology electronic treatment records of all psoriasis patients, allowing cross-validation of diagnoses and treatment records...

Psoriasis is characterized by keratinocyte resistance to apoptosis. We recently demonstrated an increase in serum tumour necrosis factor-like weak inducer of apoptosis (TWEAK) in patients after topical treatment for psoriasis. We decided to verify whether narrowband ultraviolet B (NB-UVB) has a similar effect. Serum concentration of TWEAK was estimated in patients with exacerbated plaque psoriasis treated with NB-UVB. Baseline TWEAK levels were similar in patients with psoriasis and healthy controls, and Psoriasis Area and Severity Index (PASI) correlated inversely with TWEAK levels...
