RESUMO

BACKGROUND: A systematic review failed to identify any systemic therapy used in alopecia areata (AA) where use is supported by robust evidence from high-quality randomized controlled trials. OBJECTIVE: To produce an international consensus statement on the use and utility of various treatments for AA. METHODS: Fifty hair experts from 5 continents were invited to participate in a 3-round Delphi process. Agreement of 66% or greater was considered consensus. RESULTS: In the first round, consensus was achieved in 22 of 423 (5%) questions. After a face-to-face meeting in round 3, overall, consensus was achieved for only 130 (33%) treatment-specific questions. There was greater consensus for intralesional treatment of AA (19 [68%]) followed by topical treatment (25 [43%]). Consensus was achieved in 45 (36%) questions pertaining to systemic therapies in AA. The categories with the least consensus were phototherapy and nonprescription therapies. LIMITATIONS: The study included a comprehensive list of systemic treatments for AA but not all treatments used. CONCLUSION: Despite divergent opinions among experts, consensus was achieved on a number of pertinent questions. The concluding statement also highlights areas where expert consensus is lacking and where an international patient registry could enable further research.

RESUMO

Introduction: Androgenetic alopecia is a common hair loss disorder affecting up to 80% of males by the age of 80. It is characterized by androgen related progressive thinning of hair in a defined pattern. It results in diminished self-esteem, reduced confidence and distress in affected men, irrespective of age or stage of baldness. An effective treatment for hair baldness is needed.Areas covered: In androgenetic alopecia, hair follicles undergo progressive miniaturization. Genetic factors and androgens are key role-players in disease pathogenesis. Herein the authors review the pharmacologic treatment of androgenetic alopecia, which involves 5 alpha reductase inhibitors, minoxidil and prostaglandins. Non-pharmacologic approaches are also explored.Expert opinion: Androgenetic alopecia progresses over time and although the current available medical treatments like finasteride and minoxidil are effective in arresting the progression of the disease, they allow only partial regrowth of hair at its best. Early treatment achieves a more optimal outcome. Non-pharmacologic treatments like PRP can be considered in patients refractory to medical treatment.Abbreviations: MPHL: male pattern hair loss; AGA: androgenetic alopecia; DHT: dihydrotestosterone; 5AR: 5-alpha-reductase; VEGF: vascular endothelial growth factor; PG's: prostaglandins (PG's); PGD2R: prostaglandin D2 receptor; VPA: valproic aid; SR: Serenoa Repens; PRP: platelet-rich plasma; PDGF: platelet derived growth factor; TGF: transforming growth factor; ERK: extracellular signal-regulated kinase; PKB: protein kinase B; LLLT: low-level laser therapy; ROS: reactive oxygen species; RCT: randomized control trial; SFRP1: secreted frizzled related protein 1; DP: dermal papilla; PDE5: phosphodiesterase 5.

RESUMO

BACKGROUND: Platelet-rich plasma (PRP) treatment may encourage hair growth by promoting cellular maturation, differentiation, and proliferation. OBJECTIVE: The objective of this study was to evaluate the effectiveness of PRP as a treatment for androgenetic alopecia (AGA). MATERIALS AND METHODS: A literature search combined with meta-analysis was used to calculate the overall standardized mean difference (SMD) in hair density in patients treated with PRP injections in comparison with baseline and placebo treatment. Chi squared analysis and Fisher exact test were used to investigate variation in protocols. RESULTS: The overall SMD in hair density was 0.58 (95% confidence interval [CI]: 0.35-0.80) and 0.51 (95% CI: 0.23-0.80, p < .0004) in favor of PRP treatment when compared with baseline and placebo treatment, respectively. CONCLUSION: Platelet-rich plasma is beneficial in the treatment of AGA. It is recommended that 3 monthly sessions of PRP (once monthly ×3 treatments) be used followed by a 3- to 6-month maintenance period.

RESUMO

A range of systemic treatments are used for alopecia areata with variable evidence supporting efficacy. In this systematic review, we evaluated the evidence surrounding systemic treatments for alopecia areata, alopecia totalis and alopecia universalis. A systematic search was conducted of the peer-reviewed literature published between 1946 and March 2018 via Medline, Embase, Amed, the Cochrane Central Register of Controlled Trials, PsychINFO and Lilacs. All randomised controlled trials (RCTs) that evaluated the effectiveness of systemic treatments for individuals with alopecia areata, totalis or universalis were included. Sixteen studies were included with a total of 768 participants. We found eight placebo-controlled RCTs, three RCTs comparing two systemic treatments and five RCTs comparing three treatments. A total of 15 different systemic therapies were investigated. The most frequently investigated therapy was oral prednisolone pulse therapy and oral inosiplex. There was significant variability in the definition of treatment success. No study evaluated the impact of pharmacotherapy on quality of life using complete quantitative quality of life instruments. Adverse events were reported in 13 studies and were corticosteroid related or otherwise well tolerated. Relapse rates were considerable in the four studies that reported this outcome. There is currently no specific systemic therapy that is supported by robust body of evidence from RCTs. The current evidence suggests efficacy of oral prednisolone pulse therapy and oral inosiplex. Evidence does not support the use of oral zinc sulphate, alefacept and efalizumab. Future RCTs should be adequately powered and employ clearly defined clinical response endpoints to allow future meta-analyses.

RESUMO

BACKGROUND: Secukinumab is a human interleukin-17A antagonist indicated for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy. The objective of this analysis was to measure the treatment response on psoriasis-related itching, pain, and scaling via the Psoriasis Symptom Diary (PSD)(©). METHODS: ERASURE (n = 738) and FIXTURE (n = 1306) were double-blind, multicenter phase 3 studies in adults randomized to secukinumab (300, 150 mg, n = 1144) or placebo (n = 574) (administered at Weeks 0, 1, 2, 3, and 4, followed by dosing every 4 weeks) or a biologic active control (FIXTURE only). Patient-reported itching, pain, and scaling were assessed during the first 12 weeks of treatment using the PSD. The results reported here are limited to subjects in the secukinumab and placebo treatment groups who completed the PSD. The proportions of subjects achieving prespecified responses (improvement:reduction of at least 2.2 points for itching, 2.2 points for pain, or 2.3 points for scaling) were compared for secukinumab versus placebo. RESULTS: Overall, 39% of subjects completed the PSD at baseline and Week 12 (n = 453 secukinumab; 225 placebo). Subjects treated with secukinumab achieved significantly greater improvements in itching, pain, and scaling at Week 12 versus placebo (all P < 0.0001) and had significantly greater proportions of itching, pain, and scaling responders at Week 12 versus placebo (all P < 0.05). CONCLUSION: Secukinumab significantly improves patient-reported itching, pain, and scaling in adults with moderate to severe psoriasis compared with placebo.

RESUMO

OBJECTIVES: To report the burden and cost of non-melanoma skin cancer (NMSC) treatments in Australia and to project estimates of numbers and costs to 2015. DESIGN AND SETTING: Retrospective study of data obtained from Medicare Australia for NMSC treated by excision, curettage, laser or cryotherapy between 1 January 1997 and 31 December 2010, by year, sex, age group and state or territory. MAIN OUTCOME MEASURES: Total number, total Medicare Benefits Schedule (MBS) benefit and total cost in Australian dollars of NMSC treatments. RESULTS: The total number of NMSC treatments increased from 412 493 in 1997 to 767 347 in 2010, and we estimated that the number of treatments would increase to 938 991 (95% CI, 901 047-976 934) by 2015. The total MBS benefit for NMSC treatments in 2010 was $93.5 million, and we estimated that this will increase to $109.8 million (95% CI, $105.9-$113.7 million) by 2015, whereas the total cost with inflation (ie, cost which includes diagnosis, treatment and pathology) was $511.0 million in 2010, estimated to increase to $703.0 million (95% CI, $674.6-$731.4 million) by 2015. CONCLUSION: NMSC treatments increased by 86% between 1997 and 2010. We anticipate that the number and the total cost without inflation of NMSC treatments will increase by a further 22% between 2010 and 2015. NMSC will remain the most costly cancer and place an increasing burden on the Australian health care system.

RESUMO

BACKGROUND: The comparative effects of biological response modifiers (BRMs) on the severity of psoriasis and its effects on health-related quality of life (HRQoL) have not been evaluated. OBJECTIVE: To conduct a meta-analysis to assess the effects of available biological agents on the severity of psoriasis, as well as to provide data on the effects of these agents on HRQoL. METHODS: Medline and other databases were searched for randomized controlled trials (>or= 10 weeks' duration in adults) comparing biological therapies for moderate-to-severe psoriasis with placebo. A Mantel-Haenszel fixed-effects model was employed to estimate the pooled relative risks (RR) of patients achieving >or= 75% reduction of baseline Psoriasis Area and Severity Index (PASI 75) after >or= 10 weeks of treatment. Similar analyses were also conducted on PASI 50 and PASI 90. Using a random-effects model, we estimated the likelihood of achieving PASI 50, PASI 75, and PASI 90 at 10-12 weeks and 24 weeks. Data on the effects of different BRMs (vs. placebo) on HRQoL were also presented. Numbers (%) of patients discontinuing treatment were presented as a general index of drug tolerability. RESULTS: Patients receiving infliximab 5 mg/kg intravenously at weeks 0, 2, and 6, then every 8 weeks, had the highest RR of achieving PASI 75, with a pooled RR value of 25.48 (95% confidence interval [CI], 14.04-46.23); followed by etanercept 50 mg administered subcutaneously (SC) twice weekly with RR = 11.92 (95% CI, 8.17-17.39); etanercept 25 mg SC twice weekly with RR = 10.68 (95% CI, 6.15-18.57); efalizumab 1-2 mg/kg SC per week with RR = 7.47 (95% CI, 5.20-10.73); and alefacept administered weekly (various doses) with RR = 3.37 (95% CI, 2.18-5.23). (All RR values were estimated vs. placebo.) Similar findings were observed with regard to proportions of patients achieving PASI 50 and PASI 90. The random-effects analysis suggested that infliximab significantly increased the likelihood of achieving PASI 50, PASI 75, and PASI 90 compared with placebo at 10-12 weeks; however, there were no significant differences between biological treatments at 24 weeks. Each BRM improved HRQoL compared with placebo according to findings from the Dermatology Life Quality Index. Proportions of patients discontinuing treatment were similar in active-treatment and placebo groups. CONCLUSIONS: Infliximab significantly reduced disease severity by both fixed- and random-effects models. All biological therapies improved HRQoL compared with placebo, and proportions of patients discontinuing treatment were similar in active-treatment and placebo groups. The analysis is potentially limited by statistical factors and did not systematically account for different toxicity profiles, but the findings establish a foundation for head-to-head comparative trials.

RESUMO

To determine the comparative efficacy of tap water iontophoresis to iontophoresis with the anticholinergic glycopyrrolate, we undertook a single-blinded right-left comparison study in 20 patients with palmoplantar hyperhidrosis. Most patients had their palms treated and one patient had the soles treated. We compared the duration of symptom relief following iontophoresis with glycopyrrolate unilaterally to iontophoresis with glycopyrrolate bilaterally. Patients filled in daily efficacy assessment cards. Each palm was rated as 'dry', 'slightly wet', 'moderately wet' or 'very wet'. Following treatment with unilateral tap water iontophoresis, unilateral glycopyrrolate and bilateral glycopyrrolate, patients reported hand dryness for a median of 3, 5 and 11 days, respectively. As the data was paired, treatment differences were analysed using a sign-rank test. Bilateral glycopyrrolate was superior to both unilateral glycopyrrolate and tap water in most patients. Unilateral glycopyrrolate was superior to tap water in most patients. All differences between groups were found to be statistically significant. We postulate that the increased efficacy of bilateral glycopyrrolate when compared with unilateral glycopyrrolate relates to its systemic absorption. We conclude that glycopyrrolate iontophoresis is more effective than tap water iontophoresis in the treatment of palmoplantar hyperhidrosis and that glycopyrrolate iontophoresis has both local and systemic effects on perspiration.

RESUMO

We report a 24-year-old woman with androgenetic alopecia who became sensitized to topical minoxidil following use of an extemporaneous preparation of minoxidil 4% with retinoic acid in a propylene glycol base. She subsequently also became sensitized to saw palmetto (Serenoa repens), a topical herbal extract commonly promoted for the treatment of hair loss.
