Psoralen cream plus ultraviolet A photochemotherapy (PUVA cream): our experience

[UV phototherapy : UV phototherapy and photodiagnostics-a practical overview]

UV phototherapy is an essential and efficient therapeutic option in the treatment of dermatological diseases. It is an integral part of multiple guidelines and maintains its high clinical significance despite the development of new therapeutic options for systemic treatment. Due to the difficult revenue situation, the market for ready-to-use products of psoralen and UV therapy devices is constantly changing.

Lichen planus of the lower limbs: successful treatment with psoralen cream plus ultraviolet A photochemotherapy

Lichen planus (LP) classifies into different subtypes depending on morphology and localization. Localized LP of the lower limb (LPLL) manifests a great challenge due to persistent itching, therapeutic resistance and the risk to develop into SCC. We report two cases with LPLL refractory to standard topical therapy, which were successfully treated with psoralen cream plus UVA photochemotherapy (cream-PUVA). We propose cream-PUVA as an alternative therapeutic option effective for localized LP of the lower limbs.

[Methods and means for pigmentation and depigmentation. Sense or nonsense?]

Treatment of hyperpigmentation disorders can be a lengthy process. There are several topical treatment options and hydroquinone is the most frequently used. Both combination and monotherapy are employed. These treatment options apply primarily to epidermal hyperpigmentation disorders. Dermal hyperpigmentation disorders cannot yet be effectively managed with currently available therapeutic approaches. Cosmetic disfigurement caused by hypomelanosis, especially vitiligo, can constitute a serious impairment for the patient. So far there is no definitive remedy. Better cosmetic results are generally reported for combination therapies.

Therapeutic options for palmoplantar pustulosis

Palmoplantar pustulosis (PPP) is a common chronic and recurrent pustular dermatosis characterized by multiple sterile pustules and erythematous plaques on the palms and soles. The exact cause and pathogenesis of the disease remain unknown, and there is still debate about whether PPP is a variant of psoriasis or a distinct condition. A review of the medical literature revealed that a wide range of treatments have been used in the treatment of PPP over the years. The literature in PPP is restricted to case reports or small case series, and there is a lack of well-documented clinical studies, which makes it difficult to select an ideal therapy for the condition. The purpose of this review is to discuss the current therapy options for PPP, based on results of randomized controlled trials.

Comparison of the efficacy of local narrowband ultraviolet B (NB-UVB) phototherapy versus psoralen plus ultraviolet A (PUVA) paint for palmoplantar psoriasis

Palmoplantar psoriasis is an idiopathic disabling condition, often resistant to conventional therapies. The purpose of this study was to evaluate the efficacy and safety of local narrowband ultraviolet B (NB-UVB) phototherapy and to compare it with local psoralen plus ultraviolet A (PUVA) paint in patients with palmoplantar psoriasis unresponsive to conventional therapies other than phototherapy. A cohort of 25 patients with palmoplantar psoriasis were included in this study, which was based on a left-to-right comparison pattern. The treatments were administered with local narrowband UVB irradiation on one side and local PUVA on the other side three times a week over 9 weeks. Clinical assessments were performed at baseline and every 3 weeks during the 9-week treatment. There was a statistically significant decrease in the mean clinical scores at the third, sixth and ninth week with both treatments. The difference in clinical response between the two treatment modalities was statistically significant at the end of the treatment period, with the percentage reduction in severity index scores with the PUVA-paint-treated side being 85.45% compared with 61.08% for the NB-UVB treated side (t = 5.379, P = 0.0001, Student's t-test for unpaired samples). Our results show that, although some clinical improvement was achieved with local NB-UVB phototherapy, the results were better with local PUVA, and such a treatment option may be reserved for patients with palmoplantar psoriasis who experience phototoxic reaction to psoralens.
