What Is Light Therapy
When you receive light therapy for psoriasis, your skin is exposed to an ultraviolet light. Also known as phototherapy, therapeutic exposure to UV light controls the type and wavelength of the light in safe and effective doses. With ultraviolet light therapy, inflammation of the skin is reduced and the growth of the skin cells slows. These effects from light therapy help to minimize current areas of psoriatic plaques and reduce the formation of new patches. Depending on the number of areas of severe plaque, light therapy for psoriasis may be targeted to just one part of your body. In cases of more widespread plaques, the UV light may be applied to your whole body.
What Is The Difference Between Home And Clinical Phototherapy
With home phototherapy a patient receives the same light treatment they would receive in a clinic. However, they use a personal-sized phototherapy unit which is used at home. These devices, first commercially available in the early 1980s, have increased in use due to their low cost and enhancement of patient quality of life.
According to an article in Dermatology Online Journal, Home phototherapy is a well-tolerated, efficacious, economical and patient friendly therapeutic option. Advantages of home phototherapy include improved quality of life, greater convenience, lower cost, and less time lost from work and social activities.
Dermatologists should strongly consider home phototherapy as a first-line treatment option for appropriately selected psoriasis patients.
S To Save On Psoriasis Treatment
Fortunately, there are ways you can manage the cost of your psoriasis treatments and lower your out-of-pocket expenses. Heres how:
1. Ask your doctor to prescribe generics. Generics are the best way to save money, Evans says. They may not be as effective as some of the newer topical creams, but they still can be quite helpful. Check your health insurance policy because, in some cases, getting your prescriptions by mail order can be less expensive than getting them from the pharmacy.
2. Do your own light therapy. If you have a $50 co-pay for doctors office visits and you need light therapy three times a week, it can cost you $600 a month. However, you can buy a home therapy unit. Theyre more expensive as an initial investment, Evans says, but if you can do it at home, you can save gas and travel time and office co-pays. If you’re considering at-home treatment, discuss it with your doctor.
4. Ask your doctor for samples. Finding the right medication can be a long road, Golomb says. Ask your doctor how long before a treatment will prove to be effective or ineffective. Knowing that will help you save money and time and prevent wear on your patience, she adds. Ask your doctor for samples before you invest in a 30- or 90-day supply. Also, pharmacy reps often leave coupons at the doctors office, which you can use to buy your medication.

What Are The Side Effects Of Light Therapy
As compared with other treatment options, light therapy poses fewer side-effects risks. Most people do not experience side effects when they are treated with phototherapy, says Shari Lipner, MD, PhD, an assistant professor of dermatology at Weill Cornell Medicine in New York City. The most common side effect is a mild sunburn reaction, and this is more likely to occur if the person is taking a medication that causes sun sensitivity.
Before receiving light therapy, patients should tell their doctor about any drugs theyre taking. The treatment also may not be an option for people who should avoid sunlight exposure, such as those with lupus.
How Much Will It Cost
The cost of a phototherapy kit will vary depending on the type. A doctor can help a person determine which device will be most effective for them. Phototherapy products vary in size from small, handheld devices to full-body surround cabinets.
Medicare insurance may cover the cost if the device is medically necessary. This will usually fall under Medicare Part B since it counts as durable medical equipment.

Uvb For The Treatment Of Refractory Uremic Pruritus
An UpToDate review on Uremic pruritus states that Refractory pruritus — Most patients with uremic pruritus will at least partially respond to emollients, topical analgesics and oral antihistamines or gabapentin. For patients who are refractory to these agents, ultraviolet B phototherapy is a therapeutic option.
Gilchrest et al examined the effect of ultraviolet -light phototherapy on severe persistent pruritus in 18 adult patients on hemodialysis. Patients were randomly assigned to 1 of 2 light sources. The experimental group received conventional sunburn-spectrum light in gradually increasing doses. The control group received time-matched exposures to long-wave ultraviolet light. All patients received 8 exposures to the entire skin surface over a 4-week treatment period 9 of 10 patients in the sunburn-spectrum group reported marked decrease in pruritus as opposed to 2 of 8 in the placebo group . Of those responding to sunburn-spectrum light, improvement usually occurred 2 to 3 weeks into treatment. Mild sunburn, noted by some patients in this group, was the only side effect . The response to phototherapy was unaffected by the presence of secondary hyperparathyroidism. The authors concluded that UV phototherapy was a safe, convenient, inexpensive and effective treatment for uremic pruritus. These researchers stated that these findings mandated further study of use of UVB in patients with uremic pruritis.
What Happens During A Light Therapy Procedure
When you undergo light therapy for psoriasis, you will be committing to treatments several times a week. The doctor will typically ask you to come in 3 to 5 times a week for a short duration of ultraviolet light exposure. During these outpatient appointments, the doctor may target your whole body with the UV lights in a booth similar to one at a tanning salon. However, if your plaques are fairly limited to one area of your body, you may receive treatment in which only that part is exposed to the light. In these cases, you may be able to receive your UVB light therapy at home with a portable lamp. Over the course of the 2 to 3 months of treatment, most patients see a quick improvement in the first few weeks. Many patients remain in remission following UV light treatments for 3 months up to a full year.
Uvb For The Treatment Of Lichen Amyloidosis
An UpToDate review on Cutaneous manifestations of amyloidosis states that Few studies have directly compared interventions, leaving uncertainty about relative efficacy. An open left-right comparison study that compared the efficacy of moderate to potent topical corticosteroids with the efficacy of ultraviolet B or psoralen plus ultraviolet A phototherapy in 20 patients with a clinical diagnosis of lichen amyloidosis found a trend towards greater reductions in patient-reported itch and skin roughness with phototherapy, but the difference was not statistically significant Treatment of primary localized cutaneous amyloidosis is not mandatory. Treatment is performed to improve symptoms and/or cosmesis. No treatment is consistently effective for macular amyloidosis and lichen amyloidosis. We suggest interventions to minimize pruritus and scratching as initial treatment . Our initial treatment approach consists of local corticosteroid therapy to reduce pruritus. Other interventions that may be useful for patients who fail to improve with these conservative measures include phototherapy, laser, dermabrasion, and systemic medications.
How Does Phototherapy Work
In phototherapy, the skin is exposed to a special type of light, emitted by a medical device commonly referred to as a phototherapy unit. These units range in size from hand-held and tabletop devices for spot treatment of small areas to cabinet or walk-in units for patients requiring full-body treatment, and can be used in a clinic or hospital setting or prescribed for use at home.
The medical lamps in these phototherapy units emit ultraviolet light in a specific wavelength that creates changes within the skin cells. The cells in most patients then begin to behave normally, which reduces or eliminates the symptoms of the skin disease.

How Much Does Xtrac Laser Therapy Cost
Most medical insurance companies cover XTRAC laser therapy if its considered medically necessary.
Aetna, for example, approves XTRAC laser treatment for people who havent responded adequately to three months or more of topical skin cream treatments. Aetna considers up to three courses of XTRAC laser treatment per year with 13 sessions per course may be medically necessary.
You may need to apply for prior approval from your insurance company. The National Psoriasis Foundation can help with appealing claims if youve been denied coverage. The foundation also offers help in finding financial assistance.
Treatment costs can vary, so you should check with your doctor on the per-treatment cost.
You may find that the XTRAC laser treatment is more expensive than the more common UVB treatment with a light box. Still, the higher cost may be offset by a shorter treatment time and longer remission period.
Preparing For Light Therapy
Your phototherapist is likely to ask you to follow certain rules during light therapy treatment. These may include the following.
- Limit your exposure to any additional ultraviolet light cover your skin when out in sunlight, and dont use sunbeds.
- Dont eat a lot of foods that contain natural psoralen, as these can make you more sensitive to ultraviolet light. These include celery, carrots, figs, citrus fruits, parsnips and parsley. Avoid these foods for at least two hours before a session.
- Dont use perfumed products, creams, ointments and lotions on treatment days, unless told to by your phototherapist.
- Dont cut your hair during your course of treatment as you may expose skin that was previously covered by hair.
Before a treatment session, let your phototherapist know about any new medicines youve started taking . This is because some medicines can make your skin more sensitive to light.
The psoralen you take for Psoralen ultraviolet A light therapy can interact with medicines for other conditions, such as warfarin and antipsychotics. These may need to be monitored during your therapy. Psoralen can also increase your response to caffeine and give you headaches or make you jittery. Your phototherapist may advise cutting down on drinks containing caffeine on the days you have light therapy treatment.

Uvb For The Treatment Of Photodermatoses
Collins and Ferguson reported that 20 patients with photodermatoses were treated with a hardening course of narrow-band ultraviolet B phototherapy in springtime. The response to phototherapy was monitored subjectively, by interviewing patients after the summer, and objectively by monochromator photo-testing, before and after phototherapy. Fifteen patients reported that treatment was worthwhile. Monochromator photo-testing after phototherapy revealed a 4-fold increase in the minimal erythema dose in those with abnormal photosensitivity to ultraviolet A wavebands. Adverse effects included erythema , pruritus and provocation of the eruption . The authors concluded that they now routinely consider narrow-band UVB phototherapy for problem photodermatoses.
An UpToDate review on Photosensitivity disorders : Clinical manifestations, diagnosis, and treatment states that Actinic prurigo — Phototherapy with narrowband UVB or psoralen plus ultraviolet A is a therapeutic option in patients with persistent symptoms . Chronic actinic dermatitis — Low-dose PUVA or narrowband UVB, initially given with oral glucocorticoids to decrease treatment-induced flares, has been effective in small case series .

Contraindications To Ultraviolet Phototherapy
An evidence-based analysis on Ultraviolet phototherapy management of moderate-to-severe plaque psoriasis 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 , melanoma, squamous cell carcinoma, aphakia, and/or basal cell carcinoma. The safety for PUVA has also not been established in pregnancy, nursing mothers, or children. There are also contraindications for patients with significant hepatic impairment and for those taking warfarin or phenytoin.
An UpToDate review on UVA1 phototherapy states that Ultraviolet A1 phototherapy is contraindicated in patients with xeroderma pigmentosum, porphyria, melanoma and nonmelanoma skin cancer, and in patients on long-term immunosuppressive therapy . UVA1 phototherapy should not be used for patients with UVA-sensitive photodermatoses or photosensitive atopic dermatitis or patients taking photosensitizing drugs. The efficacy and long-term safety of UVA1 therapy has not been evaluated and therefore should be used with caution in patients younger than 18 years.
How Well It Works
Phototherapy is usually an effective treatment for psoriasis.footnote 2 Partial to full skin clearing occurs after an average of 20 clinic treatments. More severe psoriasis may require more treatments. Using home equipment, which is less powerful than equipment at a clinic, takes 40 to 60 sessions to clear the skin.
Doses of UVB high enough to cause the skin to turn red, used with petroleum jelly or other moisturizers, can clear psoriasis plaque.
When using UVA alone, treatments may be helpful but take much longer to clear psoriasis. UVA is very effective when used with a photosensitizing drug . This combination treatment is called PUVA.

Are Laser Treatment For Psoriasis Effective
Since the excimer device is FDA approved, there are several clinical studies that prove its efficacy.
In a study published in the Journal of Dermatological Treatment, participants with psoriasis who had less than 10 percent body surface area covered in plaques were given XTRAC excimer laser treatment on all psoriasis sites across their body for a period of 12 weeks.
For the duration of the study the participants were required to stop using topical treatments such as corticosteroids, vitamin D analogues, or coal tar preparations. There were two groups, one receiving standard-dose treatment with a starting UVB dose of 70 percent, the second group receiving medium-dose treatment with a starting UVB dose of 200 percent.
The results showed there was no difference between the standard-dose or medium-dose treatments.
- 37.5 percent of participants had completely cleared psoriasis plaques
- 43.8 percent of participants had 75 percent clearance of plaques
A study published in the British Journal of Dermatology showed that 85.3 percent of people had a 90 percent or higher improvement after 13 sessions of laser treatment.
And yet another study published in the Journal of the American Academy of Dermatology showed that 50 percent of patients showed a 90 percent improvement in less than 10 treatments. They were having laser treatment twice weekly.

What Kinds Of Light Therapy Are There
Different forms of light therapy vary according to the type of light exposure and whether its combined with medication. Ultraviolet B can be delivered as broadband UVB or narrowband UVB . BB-UVB therapy was developed first, but NB-UVB is now more commonly used for its effectiveness and fewer side effects. A benefit of narrowband UVB is that patients are exposed to a more specific and therapeutic wavelength of light. UVB phototherapy is used to treat moderate to severe psoriasis.
For people with more advanced psoriasis, another form of light therapy combines ultraviolet A with a psoralen drug . In this combination therapy, known as PUVA, the patient takes the medication shortly before light treatment to boost the lights effect on the immune system.
A study published in April 2013 in the American Journal of Clinical Dermatology found that PUVA therapy was most effective among adults with moderate to severe plaque psoriasis. According to the study, between 60 and 75 percent of patients overall who received some type of light therapy achieved at least 75 percent improvement in their condition. The results were based on the Psoriasis Area and Severity Index, an assessment tool used to score a persons condition according to disease progression.
PUVA isnt without side effects, however, including a heightened risk of skin cancer, severe burn, and nausea.
