Efficacy of low-dose acitretin in the treatment of psoriasis

Abstract Objectives: Clinical experience favors low doses of acitretin to reduce adverse events but still maintain efficacy. We revisited the pivotal acitretin trials to compare the efficacy of high- versus low-dose acitretin. Materials and Methods: We analyzed data from two large randomized trials which had an 8-week, double-blinded (DB), placebo-controlled phase followed by a 16-week open-label (OL) phase. During the DB phase, patients received placebo, 10, 25, 50, or 75 mg of acitretin daily. Dose adjustment was allowed during the OL phase, during which high-dose treatment was defined as approximately 50 mg/day and low-dose as approximately 25 mg/day. Primary end points were improvement of psoriasis based on investigator static global assessment (ISGA) and reduction in affected body surface area (BSA). Results: At the end of the OL phase (week 24), treatment success rates were similar among all groups (29%-33%) - with the exception of the group receiving low-dose treatment for both DB and OL phases (47% success). Decrease in BSA was also highest in this group (73% vs. 28% to 54%). Conclusion: Individualization of acitretin dosing is crucial to minimize side effects and should lead to improved adherence and efficacy. This analysis supports the utility of low-dose acitretin for psoriasis over extended treatment periods.

Efficacy of mycophenolic acid for the treatment of psoriasis.

The efficacy of orally administered mycophenolic acid (MPA), an inhibitor of guanosine monophosphate (GMP) synthesis, for the treatment of psoriasis, was studied in a double-blind fashion. Of twenty-one patients completing the study period, ten of eleven patients treated with MPA had a greater than 25% decrease in severity score compared with only two of ten patients treated with placebo. The placebo group had a slight increase in severity score compared to almost 50% reduction in the average severity score of the MPA-treated group. After termination of the double-blind portion of the study, the placebo group was treated with MPA and showed a 60% decrease in severity score. Adverse effects encountered included anorexia, nausea, vomiting, and diarrhea. One patient had an uncomplicated episode of herpes zoster. Other than a mild decrease hemoglobin, no hematologic toxicity was noted.

抗白细胞介素17生物制剂治疗银屑病的疗效和安全性

银屑病是一种多基因遗传和环境相互作用下,主要由细胞免疫异常介导的慢性炎症性增生性皮肤病,其确切的发病机制尚未完全清楚.目前认为,白细胞介素17细胞因子对角质形成细胞的增生及异常激活十分重要,是银屑病发病机制中的关键环节.新研发的3种针对白细胞介素17通路的生物制剂已应用于银屑病的临床治疗或试验,包括直接拮抗白细胞介素17A的苏金单抗(secukinumab)、ixekizumab及通过拮抗白细胞介素17RA,从而抑制白细胞介素17下游信号分子通路的brodalumab.其治疗寻常性银屑病及关节病性银屑病的有效性和安全性在临床试验中得到肯定,给银屑病患者带来新的治疗选择,但其安全性仍需长远评价.

Efficacy and safety of ustekinumab treatment in elderly patients with psoriasis

The ratio of the elderly among psoriasis patients has been increasing. However, satisfactory long‐term management of psoriasis for the elderly is challenging because of the more frequent presence of comorbidities, and the higher risk of adverse events from systemic therapeutic agents than younger patients. The use of ustekinumab (UST) appears to be an appropriate systemic treatment because it is considered less likely to cause adverse events than other systemic treatments, as well as necessitating fewer hospital visits. Our retrospective study aimed to evaluate the efficacy and safety profile of UST in elderly patients with psoriasis. The study included 24 patients aged over 65 years (range, 65–88 years; mean, 73.1 years) with moderate to severe plaque psoriasis with impaired quality of life. Efficacy and safety were assessed over a 1‐year period using the Psoriasis Area and Severity Index (PASI) and the Dermatology Live Quality Index (DLQI). The efficacy was evaluated by the proportion of subjects who achieved ≥75% reduction in PASI score (PASI 75). PASI 75 responses were 56.5% at week 16, 59.1% at week 28, and 60.0% at week 52. None of the patients developed any serious infection during the 1‐year treatment. The mean DLQI score at weeks 0, 16, 28, and 52 was 7.8 ± 6.0, 2.5 ± 3.4, 1.4 ± 1.7, and 1.2 ± 1.7, respectively. UST showed sufficient efficacy for elderly patients with psoriasis without any serious infection over the 1‐year treatment. Our results suggest that UST is the preferable agent for the treatment of elderly patients with psoriasis.

Efficacy of the pulsed dye laser in the treatment of localized recalcitrant plaque psoriasis: a comparative study

BACKGROUND: Localized chronic plaque psoriasis, resistant to local therapy, may be very hard to treat. The treatment of these lesions with a pulsed dye laser (PDL) has been described before, but a comparative study between the PDL and a potent topical treatment has never been performed. OBJECTIVES: To compare the efficacy of the PDL in the treatment of localized, recalcitrant plaque psoriasis with a potent topical therapy, using calcipotriol/betamethasone dipropionate (Dovobet) as an active comparator. METHODS: Eight patients with psoriasis were treated with both PDL (585 nm) and calcipotriol/betamethasone dipropionate in an open, intrapatient, left-right comparison. A plaque severity score (sum score) and photographs were used to document the course of therapy. Patients reported pain on a visual analogue scale. RESULTS: Both treatments were well tolerated, although one patient left the study due to post-PDL treatment pain. A significant difference in the sum score 12 weeks after treatment was seen in favour of the PDL (62% vs. 19% reduction; P<0.05). Scores for erythema declined significantly at week 12 in both the PDL and the calcipotriol/betamethasone dipropionate group (P<0.001). Induration and desquamation scores were significantly reduced at week 12 in the PDL group, without a statistically significant reduction in calcipotriol/betamethasone-treated lesions. The pain scores declined with progressive PDL treatments, although not statistically significantly. CONCLUSIONS: PDL treatment might be considered for the treatment of localized, recalcitrant plaque psoriasis, when other topical therapies have failed.

Efficacy of topical treatment in psoriasis with MC903, a new vitamin D analogue

In 10 in-patients with chronic plaque psoriasis, the antipsoriatic effect of MC903, a new synthetic analogue of vitamin D was evaluated. In each patient two symmetrical located psoriatic plaques were selected for the study. Topical treatment with MC903 cream (containing 1.2 mg MC903 per g cream) was compared with placebo cream in a double-blind, controlled, left-right, randomized way during 6 weeks of therapy. Compared with baseline, the clinical (erythema, scaling and infiltration) improvement was significant after 1 week of therapy with MC903 cream, while lateral comparison showed MC903 cream significantly better than cream base after 4 weeks of therapy (p less than 0.05). Measurements of skin blood flow by the laser Doppler technique in evaluating the disease activity was not superior to the clinical assessments. In 3 patients the psoriatic lesions treated with MC903 cream cleared completely during 6 weeks of therapy. No essential adverse reactions were observed. MC903 has a potent effect on cell proliferation and cell differentiation, but has minimal effect on calcium metabolism. It is concluded that this synthetic vitamin D analogue is potentially useful in the treatment of psoriasis.
