Guselkumab in Patients with Scalp Psoriasis: A post hoc Analysis of the VOYAGE 2 Phase III Randomized Clinical Trial

Scalp psoriasis affects approximately 80% of patients with psoriasis and can negatively impact their quality of life. This post hoc analysis of the VOYAGE 2 Phase III randomized clinical trial evaluated scalp response to guselkumab treatment and its association with skin response and patient-reported outcomes. The study included patients with moderate-to-severe plaque psoriasis and baseline scalp psoriasis who were initially randomized to receive guselkumab. Patients were divided into 3 groups based on their achievement of a Psoriasis Area and Severity Index 90 response at week 28: responder continuation, non-responder continuation and responder withdrawal. In all 3 groups, mean Psoriasis Area and Severity Index head and scalp-specific Investigator's Global Assessment scores improved through week 28. In the responder withdrawal group, these scores worsened after treatment withdrawal at week 28, but remained stable through week 48 in both continuation groups. Trends in Dermatology Life Quality Index and Psoriasis Symptoms and Signs Diary itch scores mirrored those of mean scalp-specific Investigator's Global Assessment scores through week 48. Within-subject correlations were 0.83 between scalp-specific Investigator's Global Assessment and Psoriasis Area and Severity Index head scores and 0.78 between scalp-specific Investigator's Global Assessment and Psoriasis Symptoms and Signs Diary itch scores. Through week 252, Psoriasis Area and Severity Index head scores remained stable in the responder continuation group, improved in the non-responder continuation group and rapidly improved by week 84 in the responder withdrawal group after retreatment.

Topical corticosteroids for treating phimosis in boys

BACKGROUND

This is an updated version of a Cochrane Review first published in 2014. Phimosis is a condition in which the prepuce (foreskin) cannot be fully retracted past the head of the penis (glans). Phimosis is often treated surgically by circumcision or prepuce plasty; however, reports of non-invasive treatment using topical corticosteroids applied for four to eight weeks have suggested favorable outcomes.

OBJECTIVES

To assess the effects of topical corticosteroids applied to the stenotic portion of the prepuce for the treatment of phimosis in boys compared with placebo or no treatment.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, LILACS, and ClinicalTrial.gov. We checked reference lists of included studies and relevant reviews for additional studies. There were no restrictions on the language of publication. The date of the last search was 4 October 2023.

SELECTION CRITERIA

We included all randomized controlled trials (RCTs) that compared the use of any topical corticosteroid with placebo or no treatment for boys with any type or degree of phimosis.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies, extracted data related to the review's primary and secondary outcomes, and assessed the studies' risk of bias. We used the random-effects model for statistical analyses and expressed dichotomous outcomes as risk ratios (RRs) with 95% confidence intervals (CIs). We contacted the authors of the primary articles to request details of the study design and specific outcome data. We used GRADE to assess the certainty of evidence on a per-outcome basis.

MAIN RESULTS

In this update, we identified two new studies with 111 participants, bringing the total number of included studies to 14 (1459 randomized participants). We found that types of corticosteroids investigated, participant age, degree of phimosis, type of phimosis, and treatment duration varied considerably among studies. Compared with placebo or no treatment, topical corticosteroids may increase the complete resolution of phimosis after four to eight weeks of treatment (RR 2.73, 95% CI 1.79 to 4.16; I² = 72%; 10 trials, 834 participants; low-certainty evidence). Based on 252 complete resolutions per 1000 boys in the control group, this corresponds to 436 more complete resolutions per 1000 boys (95% CI 199 more to 796 more). We downgraded the certainty of the evidence by one level for serious study limitations and by one level for serious inconsistency. Topical corticosteroids may also increase the partial resolution of phimosis at four to eight weeks of treatment compared with placebo or no treatment (RR 1.68, 95% CI 1.17 to 2.40; I² = 44%; 7 trials, 745 participants; low-certainty evidence). Based on 297 partial resolutions per 1000 boys in the control group, this corresponds to 202 more partial resolutions per 1000 boys (95% CI 50 more to 416 more). We downgraded the certainty of the evidence by one level for serious study limitations and by one level for serious inconsistency. We are uncertain of the effect of topical corticosteroids compared to placebo on change in retractability score (standardized mean difference [SMD] -1.48, 95% CI -2.93 to -0.03; I²91%; 2 trials, 177 participants; very low-certainty evidence). We downgraded the certainty of the evidence by one level for serious study limitations, one level for serious heterogeneity, and one level for serious imprecision. Compared with placebo, topical corticosteroids may increase the long-term complete resolution of phimosis six or more months after treatment (RR 4.09, 95% CI 2.80 to 5.97; I² = 0%; 2 trials, 280 participants; low-certainty evidence). Based on 171 long-term complete resolutions per 1000 boys in the control group, this corresponds to 528 more complete resolutions per 1000 boys (95% CI 308 more to 850 more). We downgraded the certainty of the evidence by one level for serious study limitations and by one level for serious imprecision. There may be little or no difference in the risk of adverse effects between topical corticosteroids and placebo or no treatment (RR 0.28, 95% CI 0.03 to 2.62; I² = 22%; 11 trials, 1091 participants; low-certainty evidence). Only two of 11 studies that recorded adverse effects reported any adverse effects; one event occurred in the corticosteroid group and six in the control group. We downgraded the certainty of the evidence by one level for serious study limitations and by one level for serious imprecision.

AUTHORS' CONCLUSIONS

Topical corticosteroids, compared to placebo or no treatment, may increase complete and partial resolution of phimosis when assessed after four to eight weeks of treatment, and may increase long-term complete resolution of phimosis assessed six or more months after treatment. Topical corticosteroids may have few or no adverse effects, and we are uncertain about their effect on retractability scores. The body of evidence is limited by poor reporting of methods in the studies, important clinical heterogeneity, and serious imprecision in the results. Future, higher-quality trials with long-term follow-up would likely improve our understanding of the effects of topical corticoids on phimosis in boys.

Strategies for using topical corticosteroids in children and adults with eczema

BACKGROUND

Eczema is a common skin condition. Although topical corticosteroids have been a first-line treatment for eczema for decades, there are uncertainties over their optimal use.

OBJECTIVES

To establish the effectiveness and safety of different ways of using topical corticosteroids for treating eczema.

SEARCH METHODS

We searched databases to January 2021 (Cochrane Skin Specialised Register; CENTRAL; MEDLINE; Embase; GREAT) and five clinical trials registers. We checked bibliographies from included trials to identify further trials.

SELECTION CRITERIA

Randomised controlled trials in adults and children with eczema that compared at least two strategies of topical corticosteroid use. We excluded placebo comparisons, other than for trials that evaluated proactive versus reactive treatment.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods, with GRADE certainty of evidence for key findings. Primary outcomes were changes in clinician-reported signs and relevant local adverse events. Secondary outcomes were patient-reported symptoms and relevant systemic adverse events. For local adverse events, we prioritised abnormal skin thinning as a key area of concern for healthcare professionals and patients.

MAIN RESULTS

We included 104 trials (8443 participants). Most trials were conducted in high-income countries (81/104), most likely in outpatient or other hospital settings. We judged only one trial to be low risk of bias across all domains. Fifty-five trials had high risk of bias in at least one domain, mostly due to lack of blinding or missing outcome data. Stronger-potency versus weaker-potency topical corticosteroids Sixty-three trials compared different potencies of topical corticosteroids: 12 moderate versus mild, 22 potent versus mild, 25 potent versus moderate, and 6 very potent versus potent. Trials were usually in children with moderate or severe eczema, where specified, lasting one to five weeks. The most reported outcome was Investigator Global Assessment (IGA) of clinician-reported signs of eczema. We pooled four trials that compared moderate- versus mild-potency topical corticosteroids (420 participants). Moderate-potency topical corticosteroids probably result in more participants achieving treatment success, defined as cleared or marked improvement on IGA (52% versus 34%; odds ratio (OR) 2.07, 95% confidence interval (CI) 1.41 to 3.04; moderate-certainty evidence). We pooled nine trials that compared potent versus mild-potency topical corticosteroids (392 participants). Potent topical corticosteroids probably result in a large increase in number achieving treatment success (70% versus 39%; OR 3.71, 95% CI 2.04 to 6.72; moderate-certainty evidence). We pooled 15 trials that compared potent versus moderate-potency topical corticosteroids (1053 participants). There was insufficient evidence of a benefit of potent topical corticosteroids compared to moderate topical corticosteroids (OR 1.33, 95% CI 0.93 to 1.89; moderate-certainty evidence). We pooled three trials that compared very potent versus potent topical corticosteroids (216 participants). The evidence is uncertain with a wide confidence interval (OR 0.53, 95% CI 0.13 to 2.09; low-certainty evidence). Twice daily or more versus once daily application We pooled 15 of 25 trials in this comparison (1821 participants, all reported IGA). The trials usually assessed adults and children with moderate or severe eczema, where specified, using potent topical corticosteroids, lasting two to six weeks. Applying potent topical corticosteroids only once a day probably does not decrease the number achieving treatment success compared to twice daily application (OR 0.97, 95% CI 0.68 to 1.38; 15 trials, 1821 participants; moderate-certainty evidence). Local adverse events Within the trials that tested 'treating eczema flare-up' strategies, we identified only 26 cases of abnormal skin thinning from 2266 participants (1% across 22 trials). Most cases were from the use of higher-potency topical corticosteroids (16 with very potent, 6 with potent, 2 with moderate and 2 with mild). We assessed this evidence as low certainty, except for very potent versus potent topical corticosteroids, which was very low-certainty evidence.  Longer versus shorter-term duration of application for induction of remission No trials were identified. Twice weekly application (weekend, or 'proactive therapy') to prevent relapse (flare-ups) versus no topical corticosteroids/reactive application Nine trials assessed this comparison, generally lasting 16 to 20 weeks. We pooled seven trials that compared weekend (proactive) topical corticosteroids therapy versus no topical corticosteroids (1179 participants, children and adults with a range of eczema severities, though mainly moderate or severe). Weekend (proactive) therapy probably results in a large decrease in likelihood of a relapse from 58% to 25% (risk ratio (RR) 0.43, 95% CI 0.32 to 0.57; 7 trials, 1149 participants; moderate-certainty evidence). Local adverse events We did not identify any cases of abnormal skin thinning in seven trials that assessed skin thinning (1050 participants) at the end of treatment. We assessed this evidence as low certainty. Other comparisons  Other comparisons included newer versus older preparations of topical corticosteroids (15 trials), cream versus ointment (7 trials), topical corticosteroids with wet wrap versus no wet wrap (6 trials), number of days per week applied (4 trials), different concentrations of the same topical corticosteroids (2 trials), time of day applied (2 trials), topical corticosteroids alternating with topical calcineurin inhibitors versus topical corticosteroids alone (1 trial), application to wet versus dry skin (1 trial) and application before versus after emollient (1 trial). No trials compared branded versus generic topical corticosteroids and time between application of emollient and topical corticosteroids.

AUTHORS' CONCLUSIONS

Potent and moderate topical corticosteroids are probably more effective than mild topical corticosteroids, primarily in moderate or severe eczema; however, there is uncertain evidence to support any advantage of very potent over potent topical corticosteroids. Effectiveness is similar between once daily and twice daily (or more) frequent use of potent topical corticosteroids to treat eczema flare-ups, and topical corticosteroids weekend (proactive) therapy is probably better than no topical corticosteroids/reactive use to prevent eczema relapse (flare-ups). Adverse events were not well reported and came largely from low- or very low-certainty, short-term trials. In trials that reported abnormal skin thinning, frequency was low overall and increased with increasing potency. We found no trials on the optimum duration of treatment of a flare, branded versus generic topical corticosteroids, and time to leave between application of topical corticosteroids and emollient. There is a need for longer-term trials, in people with mild eczema.

Effectiveness of skin cleanser and protectant regimen on incontinence-associated dermatitis outcomes in acute care patients: A cluster randomised trial

Skin cleansers and protectants protect skin from incontinent matter to reduce the risk of incontinence-associated dermatitis (IAD), but their effectiveness treating established IAD in the tropics is unknown. We conducted an open-label cluster randomised trial to compare the effectiveness of a combined regimen of (1) specialised skin cleansers with disposable body wipes and (2) either an acrylic terpolymer (T1) or zinc oxide (T2) skin protectant against disposable body wipes and zinc oxide protectant (control) in promoting IAD healing and reducing the risk of deterioration. Eighty-four patients were recruited in a tertiary hospital in Singapore between April 2019 and January 2020 (T1: n = 23; T2: n = 37; Control: n = 24). Although not statistically significant, patients treated with T1 and T2 were 1.5 times as likely to experience IAD healing within seven days compared with the control (P = .66). Healing was more pronounced in participants with skin loss treated with T1 or T2. No treatment was superior in preventing IAD deterioration, the prevalence of which remained small (8%-14%). While skin cleaning and protectants reduced the overall risk of skin deterioration, the addition of skin cleansers enhanced IAD healing within a short period, an important consideration for future research examining IAD treatment in acute care.

Occlusive treatment enhances efficacy of tacrolimus 0.1% in a pediatric patient with severe alopecia areata: Case report and literature review

Tacrolimus is an immunomodulatory drug, available for topical and systemic treatment of several dermopathies that are characterized by immune dysregulation. In the case of alopecia areata, standard application has proven insufficient to yield satisfactory results. Herein, we present a 6-year-old patient with Down syndrome who was treated with topical tacrolimus 0.1% ointment under occlusion overnight with remarkable clinical improvement within 4 months.

Methotrexate for psoriatic arthritis

BACKGROUND

Psoriatic arthritis is an inflammatory disease associated with joint damage, impaired function, pain, and reduced quality of life. Methotrexate is a disease-modifying anti-rheumatic drug (DMARD) commonly prescribed to alleviate symptoms, attenuate disease activity, and prevent progression of disease.

OBJECTIVES

To assess the benefits and harms of methotrexate for psoriatic arthritis in adults.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, the WHO International Clinical Trials Registry Platform, and www.clinicaltrials.gov for relevant records. We searched all databases from inception to 29 January 2018. We handsearched included articles for additional records and contacted study authors for additional unpublished data. We applied no language restrictions.

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) and quasi-RCTs that compared methotrexate versus placebo, or versus another DMARD, for adults with psoriatic arthritis. We reported on the following major outcomes: disease response (measured by psoriatic arthritis response criteria (PsARC)), function (measured by the Health Assessment Questionnaire for Rheumatoid Arthritis (HAQ)), health-related quality of life, disease activity (measured by disease activity score (28 joints) with erythrocyte sedimentation rate (DAS28-ESR)), radiographic progression, serious adverse events, and withdrawals due to adverse events.

DATA COLLECTION AND ANALYSIS

Two review authors independently reviewed search results, assessed risk of bias, extracted trial data, and assessed the quality of evidence using the GRADE approach. We undertook meta-analysis only when this was meaningful.

MAIN RESULTS

We included in this review eight RCTs conducted in an outpatient setting, in Italy, the United Kingdom, the United States of America, China, Russia, and Bangladesh. Five studies compared methotrexate versus placebo, and four studies compared methotrexate versus other DMARDs. The average age of participants varied across studies (26 to 52 years), as did the average duration of psoriatic arthritis (one to nine years). Doses of methotrexate varied from 7.5 mg to 25 mg orally per week, but most studies administered approximately 15 mg or less orally per week. Risk of bias was generally unclear or high across most domains for all studies. We considered only one study to have low risk of selection and detection bias. The main study informing results of the primary comparison (methotrexate vs placebo up to six months) was at low risk of bias for all domains except attrition bias and reporting bias.We restricted reporting of results to the comparison of methotrexate versus placebo for up to six months. Low-quality evidence (downgraded due to bias and imprecision) from a single study (221 participants; methotrexate dose 15 mg orally or less per week) informed results for disease response, function, and disease activity. Disease response, measured by the proportion who responded to treatment according to PsARC (response indicates improvement), was 41/109 in the methotrexate group and 24/112 in the placebo group (risk ratio (RR) 1.76, 95% confidence interval (CI) 1.14 to 2.70). This equates to an absolute difference of 16% more responders with methotrexate (4% more to 28% more), and a number needed to treat for an additional beneficial outcome (NNTB) of 6 (95% CI 5 to 25). Mean function, measured by the HAQ (scale 0 to 3; 0 meaning no functional impairment; minimum clinically important difference 0.22), was 1.0 points with placebo and 0.3 points better (95% 0.51 better to 0.09 better) with methotrexate; absolute improvement was 10% (3% better to 17% better), and relative improvement 30% (9% better to 51% better). Mean disease activity as measured by the DAS28-ESR (scale of 0 to 10; lower score means lower disease activity; minimum clinically important difference unknown) was 3.8 points in the methotrexate group and 4.06 points in the placebo group; mean difference was -0.26 points (95% CI -0.65 to 0.13); absolute improvement was 3% (7% better to 1% worse), and relative improvement 6% (16% better to 3% worse).Low-quality evidence (downgraded due to risk of bias and imprecision) from three studies (n = 293) informed our results for serious adverse events and withdrawals due to adverse events. Due to low event rates, we are uncertain if methotrexate results show increased risk of serious adverse events or withdrawals due to adverse events compared to placebo. Results show 1/141 serious adverse events in the methotrexate group and 4/152 in the placebo group: RR 0.26 (95% CI 0.03 to 2.26); absolute difference was 2% fewer events with methotrexate (5% fewer to 1% more). In all, 9/141 withdrawals in the methotrexate group were due to adverse events and 7/152 in the placebo group: RR 1.32 (95% CI 0.51 to 3.42); absolute difference was 1% more withdrawals (4% fewer to 6% more).One study measured health-related quality of life but did not report these results. No study measured radiographic progression.

AUTHORS' CONCLUSIONS

Low-quality evidence suggests that low-dose (15 mg or less) oral methotrexate might be slightly more effective than placebo when taken for six months; however we are uncertain if it is more harmful. Effects of methotrexate on health-related quality of life, radiographic progression, enthesitis, dactylitis, and fatigue; its benefits beyond six months; and effects of higher-dose methotrexate have not been measured or reported in a randomised placebo-controlled trial.

Safety of a formulation containing chitosan microparticles with chamomile: blind controlled clinical trial

OBJECTIVE

to evaluate the safety of a topical formulation containing chamomile microparticles coated with chitosan in the skin of healthy participants.

METHOD

phase I blind, controlled, non-randomized, single-dose clinical trial with control for skin, base formulation, and formulation with microparticles. The variables analyzed were irritation and hydration by the Wilcoxon and Kruskall-Wallis tests.

RESULTS

the study started with 35 participants with a mean age of 26.3 years. Of these, 30 (85.71%) were female, 29 (82.90%) were white skinned and 32 (91.40%) had no previous pathologies. One participant was removed from the study reporting erythema at the site of application, and four other participants for not attending the last evaluation. In the 30 participants who completed the study, the tested formulation did not cause erythema, peeling, burning, pruritus or pain; there was an improvement in cutaneous hydration in the site of application of the formulation with microparticles. In the evaluation of the barrier function, there was an increase in transepidermal water loss in all sites.

CONCLUSION

the formulation with chamomile microparticles is safe for topical use, not causing irritation and improving skin hydration over four weeks of use. Its effects on barrier function need further investigation. No. RBR-3h78kz in the Brazilian Registry of Clinical Trials (ReBEC).

A systematic review and meta-analysis of the efficacy and safety of the interleukin (IL)-12/23 and IL-17 inhibitors ustekinumab, secukinumab, ixekizumab, brodalumab, guselkumab and tildrakizumab for the treatment of moderate to severe plaque psoriasis

OBJECTIVE

To systematically analyze the efficacy and safety of interleukin (IL)-12/23, IL-17, and selective IL-23 inhibitors in moderate to severe plaque psoriasis.

METHODS AND RESULTS

Twenty-four randomized placebo-controlled trials were included. Compared to placebo, risk ratios (RR) of achieving PASI-75 and PGA/IGA 0/1 respectively were 20.20 (95% CI 13.82-29.54, p < .00001) and 14.55 (10.42-20.31, p < .00001) for ustekinumab 90 mg, 13.75 (8.49-22.28, p < .00001) and 9.81 (5.70-16.89, p < .00001) for ustekinumab 45 mg, 17.65 (12.38-25.17, p < .00001) and 26.13 (16.05-42.53, p < .00001) for secukinumab 300 mg, 15.36 (10.76-21.94, p < .00001) and 20.91 (12.82-34.13, p < .00001) for secukinumab 150 mg, 18.22 (10.63-31.23, p < .000001) and 18.82 (10.36-34.16, p < .00001) for ixekizumab 80 mg every 4 weeks, 19.83 (11.07-35.52, p < .00001) and 20.41 (11.01-37.81, p < .00001) for ixekizumab 80 mg every 2 weeks, 14.79 (9.86-22.16, p < .00001) and 21.93 (15.52-31.01, p < .00001) for brodalumab 210 mg, 11.55 (7.77-17.18, p < .00001) and 16.59 (11.72-23.49, p < .00001) for brodalumab 140 mg, 12.40 (8.87-17.34, p < .00001) and 10.84 (7.91-14.85, p < .00001) for guselkumab 100 mg, 11.45 (7.45-17.58, p < .00001) and 10.97 (6.44-18.69, p < .00001) for tildrakizumab 200 mg, 11.02 (7.17-16.93, p < .00001) and 10.03 (6.45-15.59, p < .00001) for tildrakizumab 100 mg. Similar outcomes were seen for PASI-90. Safety was satisfactory for each therapy at any dose, but a slightly increased risk of withdrawal due to toxicity was observed in individuals receiving ixekizumab compared to placebo.

CONCLUSION

Ustekinumab, secukinumab, ixekizumab, brodalumab, guselkumab, and tildrakizumab were highly efficacious and generally well-tolerated when used as treatments for moderate to severe plaque psoriasis.

Drugs for discoid lupus erythematosus

BACKGROUND

Discoid lupus erythematosus (DLE) is a chronic form of cutaneous lupus, which can cause scarring. Many drugs have been used to treat this disease and some (such as thalidomide, cyclophosphamide and azathioprine) are potentially toxic. This is an update of a Cochrane Review first published in 2000, and previously updated in 2009. We wanted to update the review to assess whether any new information was available to treat DLE, as we were still unsure of the effectiveness of available drugs and how to select the most appropriate treatment for an individual with DLE.

OBJECTIVES

To assess the effects of drugs for discoid lupus erythematosus.

SEARCH METHODS

We updated our searches of the following databases to 22 September 2016: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase and LILACS. We also searched five trials databases, and checked the reference lists of included studies for further references to relevant trials. Index Medicus (1956 to 1966) was handsearched and we approached authors for information about unpublished trials.

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) of drugs to treat people with DLE in any population group and of either gender. Comparisons included any drug used for DLE against either another drug or against placebo cream. We excluded laser treatment, surgery, phototherapy, other forms of physical therapy, and photoprotection as we did not consider them drug treatments.

DATA COLLECTION AND ANALYSIS

At least two reviewers independently extracted data onto a data extraction sheet, resolving disagreements by discussion. We used standard methods to assess risk of bias, as expected by Cochrane.

MAIN RESULTS

Five trials involving 197 participants were included. Three new trials were included in this update. None of the five trials were of high quality.'Risk of bias' assessments identified potential sources of bias in each study. One study used an inappropriate randomisation method, and incomplete outcome data were a concern in another as 15 people did not complete the trial. We found most of the trials to be at low risk in terms of blinding, but three of the five did not describe allocation concealment.The included trials inadequately addressed the primary outcome measures of this review (percentage with complete resolution of skin lesions, percentage with clearing of erythema in at least 50% of lesions, and improvement in patient satisfaction/quality of life measures).One study of fluocinonide cream 0.05% (potent steroid) compared with hydrocortisone cream 1% (low-potency steroid) in 78 people reported complete resolution of skin lesions in 27% (10/37) of participants in the fluocinonide cream group and in 10% (4/41) in the hydrocortisone group, giving a 17% absolute benefit in favour of fluocinonide (risk ratio (RR) 2.77, 95% CI 0.95 to 8.08, 1 study, n = 78, low-quality evidence). The other primary outcome measures were not reported. Adverse events did not require discontinuation of the drug. Skin irritation occurred in three people using hydrocortisone, and one person developed acne. Burning occurred in two people using fluocinonide (moderate-quality evidence).A comparative trial of two oral agents, acitretin (50 mg daily) and hydroxychloroquine (400 mg daily), reported two of the outcomes of interest: complete resolution was seen in 13 of 28 participants (46%) on acitretin and 15 of 30 participants (50%) on hydoxychloroquine (RR 0.93, 95% CI 0.54 to 1.59, 1 study, n = 58, low-quality evidence). Clearing of erythema in at least 50% of lesions was reported in 10 of 24 participants (42%) on acitretin and 17 of 25 (68%) on hydroxychloroquine (RR 0.61, 95% CI 0.36 to 1.06, 1 study, n = 49, low-quality evidence). This comparison did not assess improvement in patient satisfaction/quality of life measures. Participants taking acitretin showed a small increase in serum triglyceride, not sufficient to require withdrawal of the drug. The main adverse effects were dry lips (93% of the acitretin group and 20% of the hydroxychloroquine group) and gastrointestinal disturbance (11% of the acitretin group and 17% of the hydroxychloroquine group). Four participants on acitretin withdrew due to gastrointestinal events or dry lips (moderate-quality evidence).One trial randomised 10 people with DLE to apply a calcineurin inhibitor, pimecrolimus 1% cream, or a potent steroid, betamethasone 17-valerate 0.1% cream, for eight weeks. The study reported none of the primary outcome measures, nor did it present data on adverse events.A trial of calcineurin inhibitors compared tacrolimus cream 0.1% with placebo (vehicle) over 12 weeks in 14 people, but reported none of our primary outcome measures. In the tacrolimus group, five participants complained of slight burning and itching, and for one participant, a herpes simplex infection was reactivated (moderate-quality evidence).Topical R-salbutamol 0.5% cream was compared with placebo (vehicle) over eight weeks in one trial of 37 people with DLE. There was a significant improvement in pain and itch in the salbutamol group at two, four, six, and eight weeks compared to placebo, but the trial did not record a formal measure of quality of life. None of the primary outcome measures were reported. Changes in erythema did not show benefit of salbutamol over placebo, but we could not obtain from the trial report the number of participants with clearing of erythema in at least 50% of lesions. There were 15 events in the placebo group (experienced by 12 participants) and 24 in the salbutamol group (experienced by nine participants). None of the adverse events were considered serious (moderate-quality evidence).

AUTHORS' CONCLUSIONS

Fluocinonide cream may be more effective than hydrocortisone in clearing DLE skin lesions. Hydroxychloroquine and acitretin appear to be of equal efficacy in terms of complete resolution, although adverse effects might be more frequent with acitretin, and clearing of erythema in at least 50% of lesions occurred less often in participants applying acitretin. Moderate-quality evidence found adverse events were minor on the whole. There is not enough reliable evidence about other drugs used to treat DLE. Overall, the quality of the trials and levels of uncertainty were such that there is a need for further trials of sufficient duration comparing, in particular, topical steroids with other agents.

Predictors of biologic treatment of psoriasis: a non-interventional study

Background

Biologic therapies represent a significant advance in the treatment of psoriasis. However, no studies have examined the patient characteristics predictive of biologic treatment of psoriasis. The purpose of this study was to ascertain the frequency and predictors of treatment of psoriasis with biologics in three European countries, ie, France, Spain, and the UK.

Methods

This was a cross-sectional analysis of physician-recorded demographic and clinical data on patients receiving either conventional or biologic treatments for psoriasis. Data were drawn from the Adelphi 2007 Psoriasis Disease Specific Program (DSP®), a multinational, real-world survey of patients with psoriasis consulting practicing dermatologists. The numbers of patients treated with biologic and nonbiologic agents were recorded. Data were subjected to bivariate analysis according to treatment regimen (biologic versus nonbiologic). Predictors of treatment with biologics were identified by logistic regression analysis.

Results

A total of 2,509 psoriasis patients were included in this study (1,374 from France, 561 from Spain, and 574 from the UK). Biologic use was most prevalent in Spain (19.4% of patients), followed by the UK (9.1%), and France (8.4%). In the logistic regression analysis, psoriatic arthritis was a statistically significant predictor of increased biologic use in France (odds ratio [OR] 5.38, 95% confidence interval [CI] 3.32–8.77), Spain (OR 2.71, 95% CI 1.16–6.33), and the UK (OR 8.70, 95% CI 3.65–20.83). Physician-assessed moderate-to-severe disease was also a statistically significant predictor of increased biologic use in France (OR 5.08, 95% CI 2.01–12.82), Spain (OR 11.11, 95% CI 4.33–28.57), and the UK (OR 8.55, 95% CI 1.11–66.67).

Conclusion

In this study, an average of about one tenth of psoriasis patients enrolled in Spain, France, and the UK were treated with biologics in 2007. Physician-assessed moderate-to-severe disease and presence of psoriatic arthritis were significantly associated with biologic use in all three countries.
