  • Home-Based Phototherapy for Vitiligo

    Eleftheriadou and colleagues (2014) noted that hand-held NB-UVB units are light-weight devices that may overcome the need to treat vitiligo in hospital-based phototherapy cabinets, allowing early treatment at home that may enhance the likelihood of successful re-pigmentation. The pilot Hi-Light trial examined the feasibility of conducting a large multi-center, randomized controlled trial (RCT) on the […]

  • Comparison of NB-UVB Combination Therapy Regimens for the Treatment of Vitiligo

    Zhu et al (2023) noted that vitiligo is an autoimmune disease and some guidelines for the management of vitiligo encouraged the use of NB-UVB combination therapies to enhance re-pigmentation.  In a systematic review and network meta-analysis, these researchers compared the effectiveness of current NB-UVB combination regimen at the improvement in re-pigmentation.  They searched the electronic […]

  • Oral Therapy & Narrow-Band UVB

    Lee and associates (2016) noted that systemic corticosteroids have been used to arrest the progression of vitiligo; however, side effects have been a constant issue.  In a retrospective study, these researchers examined the efficacy and side effect of oral mini-pulse (OMP) therapy with methylprednisolone (MPD) combined with narrow-band ultraviolet B (NB-UVB) for adults with non-segmental […]

  • Apremilast & Narrowband UVB for the Vitiligo Treatment

    Khemis and colleagues (2020) noted that scientific rationale and encouraging first clinical results suggested the interest of using apremilast for treating vitiligo.  In a 52-week, prospective, randomized, placebo-controlled study, these researchers compared the efficacy of apremilast in combination therapy with narrow-band ultraviolet B (NB-UVB) versus placebo and NB-UVB treatment for re-pigmentation in patients with non-segmental […]

  • Unconventional Treatments for Vitiligo

    Gianfaldoni and colleagues (2018a) stated that despite the numerous therapies of proven efficacy available for vitiligo treatment, new unconventional drugs had been introduced for the correction of cutaneous disease in the last decades.    Capecitabine is an oral prodrug of fluorouracil, used in the treatment of metastatic colon and breast cancers.  It has been reported […]

  • Topical Calcineurin Inhibitors & Phototherapy for the Vitiligo Treatment

    In a meta-analysis, Dang et al (2016) examined the effect of topical calcineurin inhibitors as monotherapy or combined with phototherapy for vitiligo treatment. These investigators searched the MEDLINE, Embase, and Cochrane central register of controlled trials databases for articles published prior to September 2014.  A total of 13 studies were included in the meta-analysis.  After […]

  • NB-UVB & Afamelanotide in Treating Vitiligo

    Grimes et al (2013) noted that many recent studies have demonstrated defects in the melanocortin system in patients with vitiligo, including decreased circulating and lesional skin levels of α-melanocyte stimulating hormone (α-MSH).  Afamelanotide is a potent and longer-lasting synthetic analog of naturally occurring α-MSH.  These investigators described the preliminary results of 4 patients with generalized […]

  • Role of topical calcineurin inhibitors in treating vitiligo

    Wong and Lin (2013) stated that topical calcineurin inhibitors (e.g., pimecrolimus and tacrolimus) are indicated for the treatment of atopic dermatitis, but they have been studied in many off-label uses.  These investigators reviewed the English language literature to define their roles in treatment of vitiligo.  Double-blind studies showed that tacrolimus 0.1 % ointment combined with […]

  • NB-UVB vs PUVA therapy in treating vitiligo

    In a double-blind randomized study, Yones et al (2007) compared the effectiveness of oral PUVA with that of narrowband-UVB (NB-UVB) phototherapy in patients with non-segmental vitiligo.  A total of 56 patients received twice-weekly therapy with PUVA or NB-UVB.  The change in body surface area affected by vitiligo and the color match of repigmented skin compared […]

  • Narrow-band UVB and vitiligo

    A number of recently published studies have demonstrated that narrow-band UVB is an effective treatment for vitiligo, and compares favorably to UVA and psoralens (e.g., Westerhof, 1997; Njoo et al, 2000; Scherschun et al, 2001).  Unlike PUVA, narrow-band UVB does not involve the use of sensitizing agents.  Narrow-band UVB is typically administered 2 to 3 […]

  • Excimer laser effectiveness for psoriasis

    Feldman et al (2002) reported on a multi-center study of the excimer laser involving 124 patients with stable mild-to-moderate plaque-type psoriasis; 32 of whom dropped out of the study before completing the course of treatment.  Patients were scheduled twice-weekly for a total of 10 treatments.  Seventy-two percent of patients who completed the treatment course achieved […]

  • High-dose vs medium-dose treating psoriasis plaques

    Asawanonda et al (2000a) reported on a dose-response study involving 13 patients with psoriasis plaques.  Varying numbers of excimer pulses were delivered at fixed doses with a range of fluences from sub-erythemogenic to supra-erythemogenic.  Lesions remained in remission with as few as a single high fluence (up to 16 times the minimal erythemogenic dose (MED)) […]

  • Contraindications to Ultraviolet Phototherapy

    An evidence-based analysis on “Ultraviolet phototherapy management of moderate-to-severe plaque psoriasis” (Medical Advisory Secretariat, 2009) noted that there are a range of contraindications for UVB phototherapy and for PUVA. Both treatments have contraindications including any history of light sensitivity disorders (i.e., lupus erythematosus, porphyria, cutanea tarda, xeroderma pigmentosum etc.), melanoma, squamous cell carcinoma, aphakia, and/or […]

  • NB-UVB Phototherapy for the Cutaneous Mastocytosis Treatment

    Brazzelli et al (2012) stated that mastocytosis represent a heterogeneous group of stem cell disorders marked by an abnormal hyperplasia and accumulation of mast cells in one or more tissues, including bone marrow, gastro-intestinal (GI) tract, liver, spleen, lymph nodes and skin. Indolent systemic mastocytosis (ISM) is characterized by red-brownish and pruriginous maculopapular lesions, a […]

    The American Academy of Dermatology (AAD) states that “topical agents form the mainstay of treatment in psoriasis and all other treatment modalities are often used with concomitant topical therapy. Emollients increase the transmission of UV radiation by altering the optical properties of psoriatic skin lesions and improving therapeutic efficacy. Application of a thin layer of […]

  • Medical usage of phototherapy in childhood

    Veith et al (2011) noted that phototherapy is used for the medical care of cutaneous conditions that do not respond to topical or systemic medical agents, and for conditions that require broad exposure to UV as a stabilizing agent for disease. Numerous wavelengths and delivery devices of UV light are used in childhood. This article […]

    Pugashetti and colleagues (2010) noted that BB-UVB phototherapy has demonstrated effectiveness in the treatment of cutaneous disorders including psoriasis, AD, uremic pruritus and idiopathic pruritus. In the last decade, there has been a rapidly escalating process of replacing BB-UVB phototherapy units with NB-UVB equipment, as studies have demonstrated that NB-UVB (ranging from 311 mm to […]
