Phototherapy involves repeated exposure of the skin to ultraviolet light to treat various inflammatory skin conditions such as psoriasis. Recent studies have identified specific immunologic effects of phototherapy that Psoriasis-Phototherapie underlie phototherapy efficacy.

Furthermore, Psoriasis-Phototherapie advancements have been made in Psoriasis-Phototherapie safe and effective targeted phototherapy modalities for difficult-to-treat areas such as scalp psoriasis. Targeted phototherapy in the form of the excimer Psoriasis-Phototherapie holds potential for more aggressive, effective treatment and long-lasting remission of psoriasis.

Phototherapy is now also used successfully with biologic agents as combination therapy to treat recalcitrant psoriasis. Therefore, though Psoriasis-Phototherapie of the oldest therapeutic Psoriasis-Phototherapie for psoriasis, phototherapy Psoriasis-Phototherapie a mainstay treatment with promise for further advancement.

Phototherapy involves repeated Psoriasis-Phototherapie of the skin to ultraviolet UV light to treat various Psoriasis-Phototherapie skin conditions such as psoriasis, eczema, and vitiligo. This therapy is one of the oldest treatment modalities in dermatology, dating back to the ancient Egyptians, Psoriasis-Phototherapie used Psoriasis-Phototherapie light in combination with herbal extracts to treat skin disease Psoriasis-Phototherapie. Phototherapy continues to be a highly preferred treatment by dermatologists 2 ; however, Psoriasis-Phototherapie use has been decreasing in the Psoriasis-Phototherapie decades 3.

The cause of this decline is likely multifactorial, including lack of training 4Psoriasis-Phototherapie insurance Psoriasis-Phototherapie rates, and increase Psoriasis-Phototherapie cost of phototherapy treatments Psoriasis-Phototherapie. Developments have Psoriasis-Phototherapie made in the past several decades to make phototherapy an effective, convenient, and accessible treatment option for patients; however, despite research efforts, there is still much to be learned about phototherapy, including mechanism of action and how best to Psoriasis-Phototherapie effectiveness of treatments.

This review will focus on recent advances in phototherapy for the treatment of psoriasis, including new information Psoriasis-Phototherapie the possible impact Psoriasis-Phototherapie UV light on the Psoriasis-Phototherapie environment, new methods of delivering targeted light treatments Psoriasis-Phototherapie efficient yet safe methods, and using phototherapy in combination with biologic Psoriasis-Phototherapie to treat recalcitrant psoriasis.

There are three Psoriasis-Phototherapie types of phototherapy used the treatment of psoriasis: BB-UVB was the first to be developed, in the s, and Psoriasis-Phototherapie wavelengths Psoriasis-Phototherapie light Psoriasis-Phototherapie between and nm.

NB-UVB, Psoriasis-Phototherapie emits wavelengths of between and nm, was developed in the late s when studies demonstrated that wavelengths of around nm were please click for source effective than broad-spectrum UVB in clearing psoriasis.

Phototherapy is most commonly administered in the Psoriasis-Phototherapie setting in stand-up light booths. Psoriasis-Phototherapie is relatively well tolerated, and the most Psoriasis-Phototherapie side effect is burning Psoriasis-Phototherapie itching. There is no overwhelming evidence for increased risk of skin cancers except in Caucasian Psoriasis-Phototherapie who have Psoriasis-Phototherapie more than treatments of systemic PUVA 9.

Phototherapy Psoriasis-Phototherapie in a hospital or office setting are inconvenient and unfeasible for some patients.

Many patients have difficulty committing to the phototherapy regimen in the office because Psoriasis-Phototherapie time restraints, transportation Psoriasis-Phototherapie, mobility issues, and high insurance co-pays For these Psoriasis-Phototherapie, home UV units have been developed.

The use of home phototherapy for patients with psoriasis was first reported in Psoriasis-Phototherapie a study from Sweden in patients who lived in remote Psoriasis-Phototherapie far from their nearest hospital phototherapy unit Psoriasis-Phototherapie phototherapy is associated with lower burden of treatment and increased patient satisfaction This contributes to the hyperproliferation and inflammation seen Psoriasis-Phototherapie psoriasis.

There are various mechanisms by which phototherapy may be effective for psoriasis First, Psoriasis-Phototherapie light induces apoptosis of Psoriasis-Phototherapie and T cells in the epidermis and dermis Second, UV light promotes immunosuppression by promoting Psoriasis-Phototherapie of Langerhans cells out of the epidermis 15 as well as decreasing mast cell degranulation and histamine release Psoriasis-Phototherapie Lastly, UV Psoriasis-Phototherapie induces alterations Psoriasis-Phototherapie the cytokine profile of psoriasis.

Research Psoriasis-Phototherapie the last 5 years has led to a better understanding of Psoriasis-Phototherapie specific pathways and Psoriasis-Phototherapie that are altered by phototherapy.

These Psoriasis-Phototherapie on cytokines appear to be systemic and Psoriasis-Phototherapie just localized to psoriatic Psoriasis-Phototherapie. Furthermore, regulatory T Treg cells of patients with severe psoriasis display an enhanced propensity to Psoriasis-Phototherapie into ILA-producing Psoriasis-Phototherapie, which is linked to loss of forkhead box P3 Foxp3 UVB increases Foxp3-positive Treg cells in psoriatic skin lesions Whole-body phototherapy is limited in Psoriasis-Phototherapie there can be needless exposure of uninvolved skin and no benefit to unexposed skin such as the hair-covered Psoriasis-Phototherapie. In the last decade, various portable and lightweight handheld phototherapy units have become available Psoriasis-Phototherapie the treatment of localized psoriasis in the office and at home Table 1 22 These handheld devices, as compared with full-body irradiance in Psoriasis-Phototherapie booth or by a panel, have the added benefit of limiting skin exposure to UV light.

The handheld devices are useful for the treatment of scalp psoriasis as well as recalcitrant localized psoriasis Psoriasis-Phototherapie. For example, the Dermalight 90 by National Biological Corporation has a comb attachment that permits direct application of light to scalp lesions.

Although large-scale clinical trials are lacking, such light combs appear to be efficacious Psoriasis? alai emdeuge longer remission compared with topical treatments 24Psoriasis-Phototherapie The DuaLight by Theralight, Inc.

Two Psoriasis-Phototherapie for home administration of Psoriasis-Phototherapie are patient adherence and the possibility of overuse, underuse, and inappropriate use Fortunately, various features have been developed in recent years to increase safety of home phototherapy. Features wie die Tabletten für Psoriasis Mama nehmen Psoriasis-Phototherapie an integrated timer and automated calibration can Psoriasis-Phototherapie the length of time of treatment sessions and number Psoriasis-Phototherapie treatment sessions between follow-up visits Psoriasis-Phototherapie the physician.

However, proper screening of Psoriasis-Phototherapie and patient education continue to be Psoriasis-Phototherapie to ensure safety and compliance For the physician, an increasing number of resources are now available to increase knowledge and ease of Psoriasis-Phototherapie home phototherapy units In addition Psoriasis-Phototherapie targeted therapy in the form of handheld devices, the nm Psoriasis-Phototherapie laser was developed in as a targeted NB-UVB source for the treatment Psoriasis-Phototherapie psoriasis The advantage to using the Psoriasis-Phototherapie laser is that because psoriasis plaques Psoriasis-Phototherapie take Psoriasis-Phototherapie doses of light compared with normal skin, targeted treatment of psoriasis lesions using higher doses permits quicker time to clearance.

Compared with traditional whole-body phototherapy, the excimer laser required fewer visits In another study, 13 out Psoriasis-Phototherapie 26 Psoriasis-Phototherapie with plaque-type psoriasis had continued clearance or long-term improvement after 1 Psoriasis-Phototherapie These initial studies tested the excimer laser in patients with localized psoriasis and thus the excimer Psoriasis-Phototherapie is currently Psoriasis-Phototherapie Food and Drug Psoriasis-Phototherapie indicated for the treatment of mild Psoriasis-Phototherapie moderate psoriasis.

However, the excimer laser may also be safe and effective for use in Psoriasis-Phototherapie, moderate to Psoriasis-Phototherapie psoriasis However, the downside to treating moderate to severe psoriasis is the long duration required per session to treat a large body surface area, which may not be feasible in many dermatology Psoriasis-Phototherapie settings.

Another area of recent advancement for the excimer laser is in the dosimetry protocol. Psoriasis-Phototherapie dose is increased as tolerated according to degree of erythema at Psoriasis-Phototherapie treatment session A limitation Psoriasis-Phototherapie the current dosing method is that because Psoriasis-Phototherapie MED and Fitzpatrick skin type are based Psoriasis-Phototherapie normal skin, the starting dose is typically an underestimate.

It typically takes 5 to 10 treatments of incremental dose increase just to reach Psoriasis-Phototherapie ideal maximum dose of the plaque. The patients then are Psoriasis-Phototherapie just below Psoriasis-Phototherapie dose.

This please click for source plaques Psoriasis-Phototherapie be treated at the most aggressive possible Psoriasis-Phototherapie though still a tolerable one to achieve faster clearing. The Psoriasis-Phototherapie dose used in this protocol is 8 to 16 Psoriasis-Phototherapie the MED, compared with 2 to 4 times the MED of the currently accepted dosing protocol.

Although several biologic agents showing excellent efficacy in the treatment of moderate to severe psoriasis have been developed in the Psoriasis-Phototherapie decade, phototherapy Psoriasis-Phototherapie to play an important role in a subset of patients with severe, recalcitrant psoriasis despite treatment Psoriasis-Phototherapie a biologic agent.

Several studies have demonstrated the efficacy of using etanercept and NB-UVB in combination click the following article Psoriasis-Phototherapie go here These studies evaluated this combination therapy in patients Basen-Gleichgewicht und Psoriasis had not previously received treatment, patients who had an inadequate response with etanercept alone 50 mg once-weekly or 50 mg twice-weekly dosingor patients who had an inadequate response to NB-UVB alone.

Overall, combination therapy was superior Psoriasis-Phototherapie time to Psoriasis-Phototherapie was reduced. A study by Lynde et al.

High adherence to the NB-UVB regimen was defined as missing see more more than two treatments in any 4-week period. Psoriasis-Phototherapie head-to-head pilot study by Park et al. However, this study was limited by a small sample size of 13 patients. Furthermore, the patients all had Psoriasis-Phototherapie body mass index BMI of greater than 30, and studies Psoriasis-Phototherapie reported a suboptimal response to Psoriasis-Phototherapie in psoriasis patients with a BMI of greater than 30 40Psoriasis-Phototherapie Adalimumab or ustekinumab in Psoriasis-Phototherapie with NB-UVB has please click for source Psoriasis-Phototherapie investigated in a limited number of studies.

A study by Psoriasis-Phototherapie et al. Both studies demonstrated that phototherapy significantly accelerates therapeutic response and Psoriasis-Phototherapie the clearance of psoriatic lesions in patients who received Psoriasis-Phototherapie treatment.

One Psoriasis-Phototherapie to date has evaluated the combination of ustekinumab with the Psoriasis-Phototherapie laser This was an just click for source, half-body comparison study in which PASI was achieved significantly more often on the UV-irradiated half than on the non-irradiated half at week 6 in patients on ustekinumab.

Psoriasis-Phototherapie general, Psoriasis-Phototherapie therapy involving a biologic Psoriasis-Phototherapie with NB-UVB phototherapy was very well tolerated. The most common side effect was erythema. Although long-term studies do not currently exist, no skin cancers were reported throughout Psoriasis-Phototherapie duration of the Psoriasis-Phototherapie trials. Although phototherapy horn Kurve Behandlung von one of the oldest therapeutic modalities for psoriasis, it remains a mainstay treatment Psoriasis-Phototherapie holds promise for further advancement.

Recent studies have delineated specific immunologic mediators that are affected by UV light. Such Psoriasis-Arthritis Methotrexat-Injektionen in Psoriasis-Phototherapie lead to Psoriasis-Phototherapie of targets for future psoriasis Psoriasis-Phototherapie. Another area of recent advancement is in targeted phototherapy. Psoriasis-Phototherapie phototherapy is Psoriasis-Phototherapie in that it is a user-friendly tool that can irradiate Psoriasis-Phototherapie areas as well as deliver higher Psoriasis-Phototherapie of Psoriasis-Phototherapie light compared with the traditional, whole-body phototherapy treatments.

Currently, there are limited studies evaluating efficacy of handheld UVB use, and future studies should be conducted to evaluate long-term efficacy, cost effectiveness, and patient satisfaction. Psoriasis-Phototherapie topics of future studies include the development of an effective dosimetry protocol for handheld Psoriasis-Phototherapie devices that can Psoriasis-Phototherapie used safely both in the office setting and by patients at home.

Future areas of research for the excimer laser include large-scale, long-term studies evaluating its use for the treatment of moderate to severe psoriasis as a potential new indication.

Psoriasis-Phototherapie, NB-UVB appears to Psoriasis-Phototherapie a safe and effective Psoriasis-Phototherapie to be used concomitantly with biologic agents for recalcitrant psoriasis.

Long-term, large-scale studies Psoriasis-Phototherapie needed to better understand safety of the use of Psoriasis-Phototherapie combination therapy, especially pertaining to the risk of non-melanoma skin cancer. Cost Psoriasis-Phototherapie, patient Psoriasis-Phototherapie, and quality Psoriasis-Phototherapie life with this combination therapy should also be studied.
