Pediatric Pharmacology for the Primary Care Provider: Advances and Limitations

Despite >1 in 5 children taking prescription drugs in the United States, off-label drug use is common. To increase the study of drugs in children, regulatory bodies have enacted legislation to incentivize and require pediatric drug studies. As a result of this legislation, novel trial approaches, and an increase in personnel with pediatric expertise, there have been numerous advancements in pediatric drug development. With this review, we aim to highlight developments in pediatric pharmacology over the past 6 years for the most common disease processes that may be treated pharmacologically by the pediatric primary care provider. Using information extracted from label changes between 2018 and 2023, the published literature, and Clinicaltrials.gov, we discuss advances across multiple therapeutic areas relevant to the pediatric primary care provider, including asthma, obesity and related disorders, mental health disorders, infections, and dermatologic conditions. We highlight instances in which new drugs have been developed on the basis of a deeper mechanistic understanding of illness and instances in which labels have been expanded in older drugs on the basis of newly available data. We then consider additional factors that affect pediatric drug use, including cost and nonpharmacologic therapies. Although there is work to be done, efforts focused on pediatric-specific drug development will increase the availability of evidence-based, labeled guidance for commonly prescribed drugs and improve outcomes through the safe and effective use of drugs in children.

Exploring Acne Treatments: From Pathophysiological Mechanisms to Emerging Therapies

Acne vulgaris is a common dermatological condition that can present across different ages but predominantly affects adolescents and young adults. Characterized by various lesion types, the pathogenesis of acne is complex, involving genetic, hormonal, microbial, and inflammatory factors. This review comprehensively addresses current and emerging acne management strategies, emphasizing both topical and systemic treatments, procedural therapies, and dietary modifications. Key topical agents include retinoids, benzoyl peroxide, antibiotics, and other specialized compounds. Systemic options like antibiotics, hormonal therapies, and retinoids offer significant therapeutic benefits, particularly for moderate to severe cases. Procedural treatments such as laser devices, photodynamic therapy, chemical peels, and intralesional injections present viable alternatives for reducing acne symptoms and scarring. Emerging therapies focus on novel biologics, bacteriophages, probiotics, and peptides, providing promising future options. This review underscores the importance of personalized approaches to treatment due to the multifaceted nature of acne, highlighting the potential of innovative therapies for improving patient outcomes.

The Role of Herbal Medicine in the Treatment of Acne Vulgaris: A Systematic Review of Clinical Trials

Over the past few decades, interest in medicinal plants and phytochemicals for the treatment of skin disorders, including acne vulgaris, has progressively increased. Acne vulgaris is a chronic inflammatory disease of the pilosebaceous unit, which mainly occurs in adolescents and young adults. The treatment focuses on the four main factors involved in its pathogenesis: increased sebum production, hyperkeratinization, overgrowth of Cutibacterium acnes, and inflammation. The treatment includes topical retinoids, benzoyl peroxide, antibiotics, and oral isotretinoin. In this regard, the use of herbal medicine as a complementary and alternative medicine is a promising strategy. The main objective of this study was to systematically evaluate the efficacy and safety of medicinal plants and phytochemicals in the treatment of acne vulgaris. Three scientific databases (PubMed, Web of Science, and Scopus) were searched from inception to January 2021. Clinical trials comparing herbal therapies with placebo or other medicines for the treatment of acne vulgaris were included and analyzed. Outcome measures of interest comprised acne lesions (inflammatory and noninflammatory), sebum production, acne severity, and quality of life. The risk of bias in the included randomized controlled trials (RCTs) was assessed using the Cochrane risk-of-bias tool. A total of 34 clinical trials involving 1753 participants met the inclusion criteria for this systematic review. Most trials showed that herbal medicine significantly reduces inflammatory and noninflammatory acne lesions and has a relevant effect on acne severity. Some medicinal plants revealed equal or higher efficacy to standard treatments. No significant difference between groups in sebum production and quality of life was observed and no severe adverse events were reported. This systematic review provides evidence that medicinal plants and phytochemicals are promising treatments for mild to moderate acne vulgaris. However, more quality of evidence and standardized methodologies are needed to support their effectiveness and safety claims.

Management of Acne Vulgaris: A Review

IMPORTANCE

Acne vulgaris is an inflammatory disease of the pilosebaceous unit of the skin that primarily involves the face and trunk and affects approximately 9% of the population worldwide (approximately 85% of individuals aged 12-24 years, and approximately 50% of patients aged 20-29 years). Acne vulgaris can cause permanent physical scarring, negatively affect quality of life and self-image, and has been associated with increased rates of anxiety, depression, and suicidal ideation.

OBSERVATIONS

Acne vulgaris is classified based on patient age, lesion morphology (comedonal, inflammatory, mixed, nodulocystic), distribution (location on face, trunk, or both), and severity (extent, presence or absence of scarring, postinflammatory erythema, or hyperpigmentation). Although most acne does not require specific medical evaluation, medical workup is sometimes warranted. Topical therapies such as retinoids (eg, tretinoin, adapalene), benzoyl peroxide, azelaic acid, and/or combinations of topical agents are first-line treatments. When prescribed as a single therapy in a randomized trial of 207 patients, treatment with tretinoin 0.025% gel reduced acne lesion counts at 12 weeks by 63% compared with baseline. Combinations of topical agents with systemic agents (oral antibiotics such as doxycycline and minocycline, hormonal therapies such as combination oral contraception [COC] or spironolactone, or isotretinoin) are recommended for more severe disease. In a meta-analysis of 32 randomized clinical trials, COC was associated with reductions in inflammatory lesions by 62%, placebo was associated with a 26% reduction, and oral antibiotics were associated with a 58% reduction at 6-month follow-up. Isotretinoin is approved by the US Food and Drug Administration for treating severe recalcitrant nodular acne but is often used to treat resistant or persistent moderate to severe acne, as well as acne that produces scarring or significant psychosocial distress.

CONCLUSIONS AND RELEVANCE

Acne vulgaris affects approximately 9% of the population worldwide and approximately 85% of those aged 12 to 24 years. First-line therapies are topical retinoids, benzoyl peroxide, azelaic acid, or combinations of topicals. For more severe disease, oral antibiotics such as doxycycline or minocycline, hormonal therapies such as combination oral conceptive agents or spironolactone, or isotretinoin are most effective.

Guidance for the pharmacological management of acne vulgaris

INTRODUCTION

Many international guidelines and expert consensuses are available to help the clinician diagnose and treat acne vulgaris; however, a simplified practical guidance that integrates current existing published recommendations is still lacking. This article aims to give practical and simplified insight into the treatment of acne.

AREAS COVERED

Herein, the author discusses the treatment of comedonal, papulopustular, and nodular/cystic/conglobate acne. The author also proposes a simplified treatment escalation strategy that is based on disease severity and extension, starting with topical treatments for mild cases and progressing over to systemic therapies in more severe cases.

EXPERT OPINION

The ideal acne treatment would simultaneously and safely target all the pathogenic factors implicated in the appearance of acne lesions with minimal side effects. Since no such treatment currently exists, combination therapies are usually recommended for most types of acne. A major limitation in choosing an appropriate treatment plan is the discrepant use of classification systems across the published literature making it difficult to draw clear and succinct conclusions about the recommendations given. Acne is not a traditional infectious disease and so while antibiotics may improve symptoms, they do not reliably resolve the condition. Thus, there is currently a tendency to opt for antibiotic-sparing treatment strategies whenever possible.

Dermatology: how to manage acne vulgaris

Background

Acne vulgaris is the most common skin disease that can lead to disfigurement and psychological distress. This article aims to provide a narrative updated review on the management of acne vulgaris.

Methods

A PubMed search was performed with Clinical Queries using the key term “acne”. The search strategy included clinical trials, meta-analyses, randomized controlled trials, observational studies and reviews. The search was restricted to articles published in English.

Results

Treatments of acne include proper skin care, topical medications, oral medications and procedural therapies. Topical agents are the first-line treatment for mild-to-moderate acne and can be used as combination therapy for more severe acne. Systemic therapies are usually prescribed for the initial treatment of moderate-to-severe acne as well as for acne that is refractory to topical therapies.

Conclusion

Topical retinoids are the drugs of choice for the treatment and maintenance therapy of patients with mild-to-moderate acne vulgaris. Depending on the severity of the acne, topical retinoids may be used alone or in combination with benzoyl peroxide and topical or oral antibiotics. Oral antibiotics are an important therapy for inflammatory acne unresponsive to topical therapy. Neither topical nor oral antibiotics should be used as monotherapy. Oral contraceptives and/or spironolactone are useful for many women with acne. Oral isotretinoin is the drug of choice for severe, extensive, nodular acne vulgaris but is also often used in moderate cases where scarring is evident, acne-related psychosocial distress is significant or other treatment modalities have failed.

Acne - therapeutic challenges to the cooperation between a dermatologist and a cosmetologist

Acne vulgaris is one of the most common skin diseases in adolescence, causing a significant negative impact on the quality of life of young people who - in a large percentage of cases - do not accept their appearance. The complex pathogenesis of this disease requires appropriate preventive and curative treatment from both a dermatologist and a cosmetologist. The aim of the study was to discuss the methods currently used by dermatologists in local therapy for mild and intermediate forms of acne vulgaris, and to provide an overview of possible preventive and caring activities in the cosmetologist's office. Possible directions of cooperation between the dermatologist and the cosmetologist in the prevention of acne relapse and treatment of possible acne complications were also discussed.

Topical benzoyl peroxide for acne

BACKGROUND

Acne is a common, economically burdensome condition that can cause psychological harm and, potentially, scarring. Topical benzoyl peroxide (BPO) is a widely used acne treatment; however, its efficacy and safety have not been clearly evaluated.

OBJECTIVES

To assess the effects of BPO for acne.

SEARCH METHODS

We searched the following databases up to February 2019: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS. We also searched five trials registers and checked the reference lists of relevant randomised controlled trials (RCTs) and systematic reviews.

SELECTION CRITERIA

We included RCTs that compared topical BPO used alone (including different formulations and concentrations of BPO) or as part of combination treatment against placebo, no treatment, or other active topical medications for clinically diagnosed acne (used alone or in combination with other topical drugs not containing BPO) on the face or trunk.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures as expected by Cochrane. Primary outcome measures were 'participant global self-assessment of acne improvement' and 'withdrawal due to adverse events in the whole course of a trial'. 'Percentage of participants experiencing any adverse event in the whole course of a trial' was a key secondary outcome.

MAIN RESULTS

We included 120 trials (29,592 participants randomised in 116 trials; in four trials the number of randomised participants was unclear). Ninety-one studies included males and females. When reported, 72 trials included participants with mild to moderate acne, 26 included participants with severe acne, and the mean age of participants ranged from 18 to 30 years. Our included trials assessed BPO as monotherapy, as add-on treatment, or combined with other active treatments, as well as BPO of different concentrations and BPO delivered through different vehicles. Comparators included different concentrations or formulations of BPO, placebo, no treatment, or other active treatments given alone or combined. Treatment duration in 80 trials was longer than eight weeks and was only up to 12 weeks in 108 trials. Industry funded 50 trials; 63 trials did not report funding. We commonly found high or unclear risk of performance, detection, or attrition bias. Trial setting was under-reported but included hospitals, medical centres/departments, clinics, general practices, and student health centres. We reported on outcomes assessed at the end of treatment, and we classified treatment periods as short-term (two to four weeks), medium-term (five to eight weeks), or long-term (longer than eight weeks). For 'participant-reported acne improvement', BPO may be more effective than placebo or no treatment (risk ratio (RR) 1.27, 95% confidence interval (CI) 1.12 to 1.45; 3 RCTs; 2234 participants; treatment for 10 to 12 weeks; low-certainty evidence). Based on low-certainty evidence, there may be little to no difference between BPO and adapalene (RR 0.99, 95% CI 0.90 to 1.10; 5 RCTs; 1472 participants; treatment for 11 to 12 weeks) or between BPO and clindamycin (RR 0.95, 95% CI 0.68 to 1.34; 1 RCT; 240 participants; treatment for 10 weeks) (outcome not reported for BPO versus erythromycin or salicylic acid). For 'withdrawal due to adverse effects', risk of treatment discontinuation may be higher with BPO compared with placebo or no treatment (RR 2.13, 95% CI 1.55 to 2.93; 24 RCTs; 13,744 participants; treatment for 10 to 12 weeks; low-certainty evidence); the most common causes of withdrawal were erythema, pruritus, and skin burning. Only very low-certainty evidence was available for the following comparisons: BPO versus adapalene (RR 1.85, 95% CI 0.94 to 3.64; 11 RCTs; 3295 participants; treatment for 11 to 24 weeks; causes of withdrawal not clear), BPO versus clindamycin (RR 1.93, 95% CI 0.90 to 4.11; 8 RCTs; 3330 participants; treatment for 10 to 12 weeks; causes of withdrawal included local hypersensitivity, pruritus, erythema, face oedema, rash, and skin burning), erythromycin (RR 1.00, 95% CI 0.07 to 15.26; 1 RCT; 60 participants; treatment for 8 weeks; withdrawal due to dermatitis), and salicylic acid (no participants had adverse event-related withdrawal; 1 RCT; 59 participants; treatment for 12 weeks). There may be little to no difference between these groups in terms of withdrawal; however, we are unsure of the results because the evidence is of very low certainty. For 'proportion of participants experiencing any adverse event', very low-certainty evidence leaves us uncertain about whether BPO increased adverse events when compared with placebo or no treatment (RR 1.40, 95% CI 1.15 to 1.70; 21 RCTs; 11,028 participants; treatment for 10 to 12 weeks), with adapalene (RR 0.71, 95% CI 0.50 to 1.00; 7 RCTs; 2120 participants; treatment for 11 to 24 weeks), with erythromycin (no participants reported any adverse events; 1 RCT; 89 participants; treatment for 10 weeks), or with salicylic acid (RR 4.77, 95% CI 0.24 to 93.67; 1 RCT; 41 participants; treatment for 6 weeks). Moderate-certainty evidence shows that the risk of adverse events may be increased for BPO versus clindamycin (RR 1.24, 95% CI 0.97 to 1.58; 6 RCTs; 3018 participants; treatment for 10 to 12 weeks); however, the 95% CI indicates that BPO might make little to no difference. Most reported adverse events were mild to moderate, and local dryness, irritation, dermatitis, erythema, application site pain, and pruritus were the most common.

AUTHORS' CONCLUSIONS

Current evidence suggests that BPO as monotherapy or add-on treatment may be more effective than placebo or no treatment for improving acne, and there may be little to no difference between BPO and either adapalene or clindamycin. Our key efficacy evidence is based on participant self-assessment; trials of BPO versus erythromycin or salicylic acid did not report this outcome. For adverse effects, the evidence is very uncertain regarding BPO compared with adapalene, erythromycin, or salicylic acid. However, risk of treatment discontinuation may be higher with BPO compared with placebo or no treatment. Withdrawal may be linked to tolerability rather than to safety. Risk of mild to moderate adverse events may be higher with BPO compared with clindamycin. Further trials should assess the comparative effects of different preparations or concentrations of BPO and combination BPO versus monotherapy. These trials should fully assess and report adverse effects and patient-reported outcomes measured on a standardised scale.

Trends in Oral Antibiotic Prescription in Dermatology, 2008 to 2016

Importance

Dermatologists prescribe more oral antibiotic courses per clinician than any other specialty, and this use puts patients at risk of antibiotic-resistant infections and antibiotic-associated adverse events.

Objective

To characterize the temporal trends in the diagnoses most commonly associated with oral antibiotic prescription by dermatologists, as well as the duration of this use.

Design, Setting, and Participants

Repeated cross-sectional analysis of antibiotic prescribing by dermatologists from January 1, 2008, to December 31, 2016. The setting was Optum Clinformatics Data Mart (Eden Prairie, Minnesota) deidentified commercial claims data. Participants were dermatology clinicians identified by their National Uniform Claim Committee taxonomy codes, and courses of oral antibiotics prescribed by these clinicians were identified by their National Drug Codes.

Exposures

Claims for oral antibiotic prescriptions were consolidated into courses of therapy and associated with the primary diagnosis from the most recent visit. Courses were stratified into those of extended duration (>28 days) and those of short duration (≤28 days).

Main Outcomes and Measures

Frequency of antibiotic prescribing and associated diagnoses. Poisson regression models were used to assess for changes in the frequency of antibiotic prescribing over time.

Results

Between 2008 and 2016 among 985 866 courses of oral antibiotics prescribed by 11 986 unique dermatologists, overall antibiotic prescribing among dermatologists decreased 36.6% (1.23 courses per 100 visits) from 3.36 (95% CI, 3.34-3.38) to 2.13 (95% CI, 2.12-2.14) courses per 100 visits with a dermatologist (prevalence rate ratio for annual change, 0.931; 95% CI, 0.930-0.932), with much of this decrease occurring among extended courses for acne and rosacea. Oral antibiotic use associated with surgical visits increased 69.6% (2.73 courses per 100 visits) from 3.92 (95% CI, 3.83-4.01) to 6.65 (95% CI, 6.57-6.74) courses per 100 visits associated with a surgical visit (prevalence rate ratio, 1.061; 95% CI, 1.059-1.063).

Conclusions and Relevance

Continuing to develop alternatives to oral antibiotics for noninfectious conditions, such as acne, can improve antibiotic stewardship and decrease complications from antibiotic use. In addition, the rising use of postoperative antibiotics after surgical visits is concerning and may put patients at unnecessary risk of adverse events. Future studies are needed to identify the value of this practice and the risk of adverse events.

Modern pathogenetic therapy of acne

The article provides an overview of literature on new data in studying acne pathophysiology. A particular attention is given to modern interpretation of the role played by inflammation in dermatosis development. The author presents an analysis of the most effective modern pathogenetically-based topical preparations, as well as an algorithm for their application.

Approaches to limit systemic antibiotic use in acne: Systemic alternatives, emerging topical therapies, dietary modification, and laser and light-based treatments

Acne is one of the most common diseases worldwide and affects ∼50 million individuals in the United States. Oral antibiotics are the most common systemic agent prescribed for the treatment of acne. However, their use might be associated with a variety of adverse outcomes including bacterial resistance and disruption of the microbiome. As a result, multiple treatment guidelines call for limiting the use of oral antibiotics in the treatment of acne, although actual prescribing often does not follow these guidelines. In this review, the rationale for concerns regarding the use of oral antibiotics for the management of acne is reviewed. In addition, we will discuss our approach to complying with the intent of the guidelines, with a focus on novel topical agents, dietary modification, laser and light-based modalities, and systemic medications, such as spironolactone, combined oral contraceptives, and oral isotretinoin.

The efficacy and tolerability of 5-aminolevulinic acid 5% thermosetting gel photodynamic therapy (PDT) in the treatment of mild-to-moderate acne vulgaris. A two-center, prospective assessor-blinded, proof-of-concept study

BACKGROUND

Acne vulgaris is a chronic inflammatory skin disease, commonly treated with topical or systemic drugs, according to the severity of the condition. Retinoids and antibiotic compounds are considered cornerstone approaches in this condition. However, low adherence to the therapy and the issue of bacterial resistance undermine the efficacy in the long term. Photodynamic therapy (PDT) with 20% aminolevulinic acid (ALA) has shown to be effective in the treatment of inflammatory acne. Skin tolerability, however, could be a limiting factor for a widespread use of this approach. A new formulation of 5% ALA in thermosetting gel has been recently available. This formulation allows a more convenient application procedure without occlusion and better and more efficient release of the active compound in comparison with traditional ALA formulations like creams or ointments.

STUDY AIM

To evaluate in a two-center, assessor-blinded, prospective, proof-of-concept study, the efficacy, and tolerability of red-light (630 nm) PDT with a new 5-ALA "low-dose" topical gel formulation (5%) in the treatment of inflammatory mild-to-moderate acne vulgaris (AV).

SUBJECTS AND METHODS

A total of 35 subjects with moderate AV of the face (mean age: 24 ± 8 years, 13 men and 22 women) were enrolled, after their written informed consent. The primary outcome was the evolution of GAG (Global Acne Grade System) score at baseline and after an average of three, 630-nm, 15-minute, PDT sessions, performed every 2 weeks. GAG score was also calculated in a follow-up visit 6 months after the last PDT session. Skin tolerability was assessed during PDT sessions with a patient-reported discomfort level evaluation score from 0 (no discomfort at all) to 3 (severe discomfort).

RESULTS

At baseline, the GAG score was 21 ± 6. After the last PDT session, the GAG score evaluated in a blinded fashion (digital photographs) was significantly reduced to 6.5 ± 5.7, representing a 70% reduction (P = .0001, Wilcoxon test; mean difference 14.9; 95% CI of the difference: 12.1-17.6). At the follow-up visit, the GAG score was 6.7 ± 6.8. The 5% ALA thermosetting gel Red-light PDT was in general very well tolerated with a discomfort mean level score of 0.5 ± 1.

CONCLUSION

This proof-of-concept study supports the efficacy of 5% ALA thermosetting gel red-light PDT in inflammatory acne of the face with a relevant clinical improvement of inflammatory lesions with a very good tolerability profile. Clinical improvement was maintained in the medium term (Trial Registration Number: ISRCTN66066651).

Case Reports of Acne and Homeopathy

BACKGROUND

Acne vulgaris is a self-limiting disorder of the pilosebaceous unit. The aesthetic aspect of the disorder may provoke depression and diminish the quality of life. A number of agents are used for acne treatment, e.g., retinoids, antibiotics, benzoic acid, azelaic acid, and hormones. These agents have side-effects, sometimes severe ones.

CASE REPORTS

Presented are 2 cases of severe acne treated with individualized homeopathic medicines. Both patients were treated using the classical method of homeopathy, i.e., a single medicine based on the patient's individual characteristics was prescribed. The cases were documented photographically at onset and during the course of treatment. Both patients went into remission following treatment, and long-term follow-up suggested that the therapy remained efficacious long after cessation of treatment. No significant side effects were noted.

CONCLUSIONS

Homeopathic medicines may be useful as stand-alone treatment of patients with severe acne vulgaris. A case series suggested a remission rate of more than 80% using individualized homeopathic treatment. The treatment remained efficacious long after cessation and is not accompanied by significant side-effects. It is to be hoped that this presentation will stimulate research interest into homeopathic medicines as stand-alone or adjunct treatments of acne.

Trends in prescribing behavior of systemic agents used in the treatment of acne among dermatologists and nondermatologists: A retrospective analysis, 2004-2013

BACKGROUND

Despite recommendations to limit the use of oral antibiotics and increasing support for hormonal agents in the treatment of acne, it is unclear whether there have been any significant changes in practice patterns.

OBJECTIVE

To characterize changes in prescribing behavior for systemic agents in the treatment of acne in the United States between 2004 and 2013.

METHODS

We conducted a retrospective analysis using the OptumInsight Clinformatics DataMart (Optum, Eden Prairie, MN).

RESULTS

The number of courses of spironolactone prescribed per 100 female patients being managed for acne by dermatologists and nondermatologists increased from 2.08 to 8.13 and from 1.43 to 4.09, respectively. The median duration of therapy with oral antibiotics was 126 and 129 days among patients managed by dermatologists and nondermatologists, respectively, and did not change significantly over the study period.

LIMITATIONS

The OptumInsight Clinformatics DataMart lacks information on acne severity and clinical outcomes.

CONCLUSIONS

Additional work to identify patients who would benefit most from alternative therapies such as spironolactone, oral contraceptives, or isotretinoin represents a potential opportunity to improve the care of patients with acne.

Treatment effects of lysozyme-shelled microbubbles and ultrasound in inflammatory skin disease

Acne vulgaris is the most common skin disorder, and is caused by Propionibacterium acnes (P. acnes) and can induce inflammation. Antibiotic therapy often needs to be administered for long durations in acne therapy, which results in extensive antibiotic exposure. The present study investigated a new treatment model for evaluating the antibacterial effects of lysozyme (LY)-shelled microbubbles (MBs) and ultrasound (US)-mediated LY-shelled MBs cavitation against P. acnes both in vitro and in vivo, with the aims of reducing the dose and treatment duration and improving the prognosis of acne vulgaris. In terms of the in vitro treatment efficacy, the growth of P. acnes was inhibited by 86.08 ± 2.99% in the LY-shelled MBs group and by 57.74 ± 3.09% in the LY solution group. For US power densities of 1, 2, and 3 W/cm² in the LY-shelled MBs group, the growth of P. acnes was inhibited by 95.79 ± 3.30%, 97.99 ± 1.16%, and 98.69 ± 1.13%, respectively. The in vivo results showed that the recovery rate on day 13 was higher in the US group with LY-shelled MBs (97.8 ± 19.8%) than in the LY-shelled MBs group (90.3 ± 23.3%). Our results show that combined treatments of US and LY-shelled MBs can significantly reduce the treatment duration and inhibit P.-acnes-induced inflammatory skin diseases.

The prevalence of sacroiliitis in patients with acne vulgaris using isotretinoin

BACKGROUND/OBJECTIVE

Acne vulgaris is a chronic inflammatory disease affecting the pilosebaceous unit in the skin. Isotretinoin is a synthetic vitamin A derivative regarded as the most effective agent in the treatment of acne. There have recently been increasing reports of adverse effects of isotretinoin on the skeletal system. Our aim in this study was to evaluate the rheumatic side-effects triggered by this drug, and particularly the prevalence of sacroiliitis.

MATERIALS AND METHODS

A total of 73 patients receiving isotretinoin due to moderate or severe acne vulgaris were included. All patients were questioned about inflammatory low back pain and musculoskeletal pains during the treatment process. Inflammatory low back pain was evaluated using Assessment of Spondyloarthritis International Society (ASAS) criteria. Patients meeting ASAS criteria were evaluated with radiography and when necessary with sacroiliac magnetic resonance.

RESULTS

The dose range for isotretinoin was between 0.4 and 0.8 mg/kg/day (mean 0.53 mg/kg/day). Treatment lasted for 6-8 months (mean 6.8 months). Lethargy was determined in 37 (50.7%) patients, myalgia in 31 (42.5%) and low back pain in 36 (49.3%). Mechanical low back pain symptoms were present in 20 of the patients describing low back pain and inflammatory low back pain in 16. Acute sacroiliitis was determined in six patients (8.2%) following a sacroiliac magnetic resonance imaging (MRI). Five (83.3%) of the patients with sacroiliitis were female and one (16.7%) was male. No statistically significant difference was determined between male and female patients in terms of prevalence of sacroiliitis (p = 0.392).

CONCLUSION

The incidence of sacroiliitis in patients using isotretinoin is quite high. Patients using isotretinoin must be questioned about sacroiliitis findings and must be subjected to advanced assessment when necessary. Further studies regarding the development of sacroiliitis under isotretinoin therapy are now needed.

Topical, Biological and Clinical Challenges in the Management of Patients with Acne Vulgaris

Acne vulgaris is one of the most common chronic inflammatory skin disorders among adolescents and young adults. It is associated with substantial morbidity and, rarely, with mortality. The exact worldwide incidence and prevalence are currently unknown. Current challenges involve improving understanding of the underlying pathophysiology of acne vulgaris and developing a practical treatment consensus. Expert panel discussions were held in 2013 and 2014 among a group of scientists and clinicians from the Omani and United Arab Emirate Dermatology Societies to ascertain the current optimal management of acne vulgaris, identify clinically relevant end-points and construct suitable methodology for future clinical trial designs. This article reviews the discussions of these sessions and recent literature on this topic.

From new findings in acne pathogenesis to new approaches in treatment

Acne is a chronic disease of the pilosebaceous unit which is most common during adolescence. Four factors are believed to play a key role in the development of acne lesions: excess sebum production, disturbed keratinization within the follicle, colonization of the pilosebaceous duct by Propionibacterium acnes, and the release of inflammatory mediators into the skin. Consequently, in order to effectively and rapidly reduce acne lesions, treatments need to address as many of these underlying factors as possible. Currently, about half of patients have poor adherence to acne treatments. To overcome this limitation, treatments need to be developed which are well tolerated by patients, and easy for them to use, handle and apply. Topical monotherapies for acne such as retinoids and antimicrobials by themselves have a restricted range of actions against the pathogenic factors of acne. Instead, the Global Alliance to Improve Outcomes in Acne Group recommends combination therapy with a topical retinoid and an antimicrobial agent as the preferred approach for almost all acne patients. The principal advantage of such combinations is that they target more of the underlying pathogenic factors of acne than individual monotherapies and this results in faster and more complete clearing of acne lesions. Fixed-dose combinations are also more convenient than applying two medications separately, which leads to improved adherence with the regimen. By normalizing desquamation, the retinoid component of these combinations allows entry of the antimicrobial agent into the pilosebaceous unit resulting in faster clearance of P. acnes. In conclusion, topical retinoid/antimicrobial fixed-dose combinations represent a rational approach for the treatment of acne. They should be considered as the cornerstone of acne management and should be used much more in the future.

The use of oral antibiotics before isotretinoin therapy in patients with acne

BACKGROUND

Systemic antibiotics are used widely to treat moderate to severe acne, but increasing antibiotic resistance makes appropriate use a priority.

OBJECTIVE

We sought to determine the duration of systemic antibiotic use in patients with inflammatory/nodulocystic acne who eventually required isotretinoin.

METHODS

We performed a retrospective, single-site chart review of patients with acne diagnostic codes evaluated January 1, 2005 to December 31, 2014, at a dermatology practice in an academic medical center. Included patients were prescribed isotretinoin during the study period and received 30 days or more of antibiotics.

RESULTS

The average duration of antibiotic use was 331.3 days. In all, 21 patients (15.3%) were prescribed antibiotics for 3 months or less, 88 patients (64.2%) for 6 months or more, and 46 patients (33.6%) for 1 year or longer. Patients treated only at the study site had a mean duration of antibiotic treatment of 283.1 days whereas patients who also received antibiotics from another institution had a mean duration of 380.2 days. This difference approached statistical significance (P = .054).

LIMITATIONS

This study was limited to a single center.

CONCLUSION

Expert guidelines recommend responsible use of antibiotics in acne in light of emerging resistance. We found that patients who eventually received isotretinoin had extended exposure to antibiotics, exceeding recommendations. Early recognition of antibiotic failure and the need for isotretinoin can curtail antibiotic use.

A study on the prescribing pattern of drugs for acne in a tertiary care teaching hospital in odisha

BACKGROUND

Acne vulgaris is a common disease of the skin affecting the socially vulnerable young age group. There are multitudes of treatment options available but till now no studies have been reported to demonstrate the current prescribing pattern of drugs in acne vulgaris.

AIM

To study the prescribing pattern of drugs in acne in a tertiary care teaching hospital in Odisha, India.

MATERIALS AND METHODS

The study was an observational study conducted for a period of one year on patients more than 10 yeras age and having acne attending the Skin & VD OPD. Drug induced acne and acneiform eruptions were excluded.

RESULTS

A total of 1210 prescriptions of acne were analysed. The male to female ratio was 1:1.29. Most patients presented with grade 2 (60%) acne followed by grade 3 (20.99%). Out of prescribed drugs, 47.44% were oral and 52.56% were topical formulations. Oral isotretinoin (68.10%) was the most frequently prescribed drug among oral formulations. Doxycycline (54.18%) was the most preferable oral antibiotic. The average number of drugs per prescription was 3.003. Polypharmacy was preferred over monotherapy.

CONCLUSION

In the management of acne, judicious and early intervention with oral isotretinoin improves the overall treatment outcome, the fact which has increased its use in acne patients.

Common use of prescription off-label acne therapy in children younger than 12 years old

Acne is occurring more frequently in younger age groups, but most available treatments are considered off-label in young children. As the epidemiology of acne has changed to include younger children over the past 20 years, neither regulators, pharmaceutical companies, nor clinicians have understood the need or value of obtaining regulatory sanctions for problems physicians have managed using clinical judgment. The objective of this study was to analyze the frequency of off-label acne treatment according to age and other demographic factors. We searched the National Ambulatory Medical Care Survey from 1993 to 2010 for visits in children younger than 12 years of age for the diagnosis of International Classification of Diseases, Ninth Revision, code 706.1. We tabulated leading acne treatments and assessed factors associated with off-label prescribing. Off-label but appropriate acne treatments were used in 29% of acne visits for children younger than 12 years of age. Dermatologists were more likely than pediatricians to prescribe off-label treatment (p < 0.001). The most frequently used off-label treatments were topical retinoids, followed by oral antibiotics. There was no significant trend in the rate of off-label prescribing over time (p = 0.40). Off-label treatment is well within the standard of care for young children with acne. More data on the use of topical retinoids in young children will improve our understanding of their use, which may help optimize treatment outcomes for children with acne.

Efficacy of subantimicrobial dose of doxycycline in the treatment of acne of moderate severity: a review of international studie

The article analyzes the recent data concerning the new trends in the treatment of acne vulgaris of moderate severity using tetracyclines. Low-dose regimen of doxycycline is highly effective against inflammatory and noninflammatory lesions in patients with moderate acne on the face with a minority of side effects.

Use of tazarotene foam for the treatment of acne vulgaris

Acne vulgaris is a common inflammatory chronic disease of the pilosebaceous unit. It often requires long-term treatment, resulting in increased demand for topical medications that are popular with patients in order to achieve long-term compliance. Tazarotene foam 0.1% is a novel formulation of tazarotene. We review efficacy and tolerability studies of the new formulation, and suggest a possible place for the product in the management of acne vulgaris.

Development and characterization of niosomal gel for topical delivery of benzoyl peroxide

Benzoyl peroxide (BPO) is generally considered as first line treatment against acne. Low water solubility and formation of larger clusters and limited skin permeation upon topical application necessitates the application of high amount of drug for desired action which leads to induction of skin irritation. In the present study, we developed BPO-loaded niosomal formulation to improve its permeation through skin. The niosomes were further loaded in the carbopol gel to improve contact time. The results of the skin permeation study, skin retention study revealed that niosomes can effectively improve the drug permeation through skin. Application of niosomal gel significantly reduced the bacterial load after a treatment of four days. This reduction in bacterial load was further resulted in a significant reduction in the inflammation with minimal skin irritation compared with plain drug and the plain niosomal formulation.

Acne vulgaris: A review of causes and treatment options

Acne vulgaris is a disorder of the sebaceous follicle. The cause is multifactorial, and both adolescents and adults can be affected. Acne is associated with a significant financial burden and considerable psychological distress. Treatment options are reviewed, including over-the-counter medications, prescription medications, and in-office procedures.

Capability of Thailand to implement newborn male circumcision: a nation-wide survey

This study was designed to gain baseline information on the capability of the hospitals of Thailand to provide newborn male circumcision (NC) and on the opinions of health-care personnel towards NC. Two questionnaires were sent to every hospital in Thailand that might have obstetrical services. One questionnaire requested information about the degree to which NC was provided by the hospital. The second questionnaire targeted health-care providers' opinions about NC. The response rate was 55.1% (747/1355). Of the 562 hospitals that had deliveries in 2010, 8.2% (46) provided at least one NC. Thirty-eight percent (35/92) of private hospitals and 2.3% (11/470) of government hospitals provided the service. The primary reason for performing NC was parental request (82.6%). Some providers (31.3%) said that NC was easy to perform and 39.1% thought NC was safe. Most respondents (91.8%) stated that physicians should perform the procedure instead of nurses, and choices about undergoing NC should be left to parents (55.0%). NC was rarely performed in government hospitals, and its staffs seemed to not recognize the health benefits of NC. A massive education program for health-care providers would be necessary before implementing a national program for NC. More information on the opinions of health authorities, health-care personnel and parents as well as cost-effectiveness studies are needed before a proper policy can be implemented.

Evidence-based recommendations for the diagnosis and treatment of pediatric acne

INTRODUCTION

Acne vulgaris is one of the most common skin conditions in children and adolescents. The presentation, differential diagnosis, and association of acne with systemic pathology differs by age of presentation. Current acknowledged guidelines for the diagnosis and management of pediatric acne are lacking, and there are variations in management across the spectrum of primary and specialty care. The American Acne and Rosacea Society convened a panel of pediatric dermatologists, pediatricians, and dermatologists with expertise in acne to develop recommendations for the management of pediatric acne and evidence-based treatment algorithms.

METHODS

Ten major topic areas in the diagnosis and treatment of pediatric acne were identified. A thorough literature search was performed and articles identified, reviewed, and assessed for evidence grading. Each topic area was assigned to 2 expert reviewers who developed and presented summaries and recommendations for critique and editing. Furthermore, the Strength of Recommendation Taxonomy, including ratings for the strength of recommendation for a body of evidence, was used throughout for the consensus recommendations for the evaluation and management of pediatric acne. Practical evidence-based treatment algorithms also were developed.

RESULTS

Recommendations were put forth regarding the classification, diagnosis, evaluation, and management of pediatric acne, based on age and pubertal status. Treatment considerations include the use of over-the-counter products, topical benzoyl peroxide, topical retinoids, topical antibiotics, oral antibiotics, hormonal therapy, and isotretinoin. Simplified treatment algorithms and recommendations are presented in detail for adolescent, preadolescent, infantile, and neonatal acne. Other considerations, including psychosocial effects of acne, adherence to treatment regimens, and the role of diet and acne, also are discussed.

CONCLUSIONS

These expert recommendations by the American Acne and Rosacea Society as reviewed and endorsed by the American Academy of Pediatrics constitute the first detailed, evidence-based clinical guidelines for the management of pediatric acne including issues of special concern when treating pediatric patients.

Antibiotic overuse and resistance in dermatology

Antibiotics have a significant role in dermatology, treating a wide range of diseases, including acne, rosacea, inflammatory skin conditions and skin structure infections, such as cellulitis, folliculitis, carbuncles, and furuncles. Because of their consistent use, utility, and availability, antibiotics are susceptible to overuse within the medical practice, and, specific to this discussion, in the dermatologic setting. The issue of continuously increasing risk of antibiotic resistance remains an important concern to the dermatologist. The scope of this review will be to provide an overview of the common antibiotics used in the dermatologic setting with an emphasis on identifying areas of overuse, reported bacterial resistance, and discussion of clinical management aimed at decreasing antibiotic resistance.

Minocycline for acne vulgaris: efficacy and safety

BACKGROUND

Minocycline is an oral antibiotic used for acne vulgaris. Its use has lessened due to safety concerns (including potentially irreversible pigmentation), a relatively high cost, and no evidence of any greater benefit than other acne treatments. A modified-release version of minocycline is being promoted as having fewer side-effects.

OBJECTIVES

To assess new evidence on the effects of minocycline for acne vulgaris.

SEARCH METHODS

Searches were updated in the following databases to November 2011: the Cochrane Skin Group Specialised Register, CENTRAL in The Cochrane Library, MEDLINE (from 1946), EMBASE (from 1974), and LILACS (from 1982). We also searched trials registers and checked reference lists for further references to relevant randomised controlled trials (RCTs).The Cochrane Skin Group's Trials Search Co-ordinator undertook searches exploring minocycline's adverse effects in EMBASE and MEDLINE in February 2012.

SELECTION CRITERIA

We selected randomised controlled trials (RCTs) comparing minocycline, at any dose, to an active or a placebo control, in participants with inflammatory acne vulgaris. For adverse effects, we selected additional studies that reported the number of adverse effects and the number of participants treated.

DATA COLLECTION AND ANALYSIS

Outcome measures used in the trials included lesion counts, acne grades/severity scores, doctors' and participants' global assessments, adverse effects, and dropout rates. Two authors independently assessed the quality of each study. Effect sizes were calculated, and meta-analyses were undertaken where possible.Sixteen studies met the inclusion criteria for the review of adverse effects.

MAIN RESULTS

We included 12 new RCTs for this update, giving a total of 39 RCTs (6013 participants). These additional 12 RCTs have not changed the original conclusions about the clinical efficacy of minocycline.The identified RCTs were generally small and poor quality. Meta-analysis was rarely possible because of the lack of data and different outcome measures and trial durations. Although minocycline was shown to be an effective treatment for moderate to moderately-severe acne vulgaris, there was no evidence that it is better than any of the other commonly-used acne treatments. One company-sponsored RCT found minocycline to be less effective than combination treatment with topical erythromycin and zinc. No trials have been conducted using minocycline in those participants whose acne is resistant to other therapies. Also, there is no evidence to guide what dose should be used.The adverse effects studies must be interpreted with caution. The evidence suggests that minocycline is associated with more severe adverse effects than doxycycline. Minocycline, but not other tetracyclines, is associated with lupus erythematosus, but the risk is small: 8.8 cases per 100,000 person-years. The risk of autoimmune reactions increases with duration of use. The evidence does not support the conclusion that the more expensive extended-release preparation is safer than standard minocycline preparations.

AUTHORS' CONCLUSIONS

Minocycline is an effective treatment for moderate to moderately-severe inflammatory acne vulgaris, but there is still no evidence that it is superior to other commonly-used therapies. This review found no reliable evidence to justify the reinstatement of its first-line use, even though the price-differential is less than it was 10 years ago. Concerns remain about its safety compared to other tetracyclines.

Combined pharmaceuticals in the external treatment of acne: modern data

The article contains data on the efficiency of ready combined pharmaceuticals in acne treatment and discusses the synergic effect of the new adapalene / benzoyl peroxide combination.

Topical antimicrobial treatment of acne vulgaris: an evidence-based review

Topical antimicrobial treatment is indicated for mild to moderate acne vulgaris. Our literature review includes searches of Ovid, MEDLINE, EMBASE, and the databases of the Cochrane Library. A detailed search strategy is included. All searches were limited to controlled trials and systematic reviews. No year limits were applied to the searches, but we focused on trials, guidelines, and reviews published since 2004, the year that the last review of topical antimicrobials was published in this journal. Several controlled trials demonstrate that benzoyl peroxide, topical antibiotics, and topical retinoids used in combination provide the greatest efficacy and safety profile for the treatment of mild to moderate acne, but there are few trials directly comparing different combinations of these topical therapies with one another. Additionally, robust studies comparing cost and efficacy of generic combinations of the above agents with proprietary fixed-dose combination therapies that may increase compliance are also lacking. Although they have not been extensively studied, alternative agents including dapsone, salicylic acid, azelaic acid, and zinc are safe and efficacious when combined with traditional therapies.

Adapalene 0.1%/benzoyl peroxide 2.5% gel: a review of its use in the treatment of acne vulgaris in patients aged ≥ 12 years

Adapalene 0.1%/benzoyl peroxide 2.5% gel (Epiduo™, Tactuo™) is the only fixed-dose combination product available that combines a topical retinoid with benzoyl peroxide; it targets three of the four main pathophysiologic factors in acne. This article reviews the therapeutic efficacy and tolerability of topical adapalene 0.1%/benzoyl peroxide 2.5% gel in the treatment of patients aged ≥ 12 years with acne vulgaris, as well as summarizing its pharmacologic properties. In three 12-week trials in patients aged ≥ 12 years with moderate acne, success rates were significantly higher with adapalene 0.1%/benzoyl peroxide 2.5% gel than with adapalene 0.1% gel or benzoyl peroxide 2.5% gel alone, and combination therapy had an earlier onset of action. In addition, significantly greater reductions in total, inflammatory, and noninflammatory lesion counts were seen in patients receiving adapalene 0.1%/benzoyl peroxide 2.5% gel than in those receiving adapalene 0.1% gel or benzoyl peroxide 2.5% gel alone. Adapalene 0.1%/benzoyl peroxide 2.5% gel did not significantly differ from clindamycin 1%/benzoyl peroxide 5% gel in terms of the reduction in the inflammatory, noninflammatory, or total lesion counts in patients with mild to moderate acne, according to the results of a 12-week trial. Twelve-week studies showed that topical adapalene 0.1%/benzoyl peroxide 2.5% gel in combination with oral lymecycline was more effective than oral lymecycline alone in patients with moderate to severe acne, and topical adapalene 0.1%/benzoyl peroxide 2.5% gel in combination with oral doxycycline hyclate was more effective than oral doxycycline hyclate alone in patients with severe acne. In patients with severe acne who responded to 12 weeks' therapy with topical adapalene 0.1%/benzoyl peroxide 2.5% gel plus oral doxycycline hyclate or oral doxycycline hyclate alone, an additional 6 months' therapy with adapalene 0.1%/benzoyl peroxide 2.5% gel was more effective than vehicle gel at maintaining response, with further improvement seen in adapalene 0.1%/benzoyl peroxide 2.5% gel recipients. A noncomparative study also demonstrated the efficacy of 12 months' therapy with adapalene 0.1%/benzoyl peroxide 2.5% gel in patients with acne vulgaris. Topical adapalene 0.1%/benzoyl peroxide 2.5% gel was generally well tolerated in patients with acne. In 12-week trials, the most commonly occurring treatment-related adverse events included erythema, scaling, dryness, and stinging/burning; these dermatologic treatment-related adverse events were usually of mild to moderate severity, occurred early in the course of treatment, and resolved without residual effects. Topical adapalene 0.1%/benzoyl peroxide 2.5% gel was generally well tolerated in the longer term, with dry skin being the most commonly occurring treatment-related adverse event over 12 months of treatment. In conclusion, adapalene 0.1%/benzoyl peroxide 2.5% gel is a valuable agent for the first-line treatment of acne vulgaris.

Effective monitoring of isotretinoin safety in a pediatric dermatology population: a novel "patient symptom survey" approach

BACKGROUND

Assessment of adverse effects in pediatric patients on oral isotretinoin has not been standardized and the exact incidence is unknown.

OBJECTIVE

Our goal was to determine the usefulness of an isotretinoin symptom survey as a screening tool for assessment and quantification of adverse effects, including psychiatric symptoms, during isotretinoin treatment in a pediatric population of different age groups.

METHODS

We performed a retrospective chart review on a random sample of patients treated with isotretinoin at a tertiary pediatric dermatology clinic where patients completed an isotretinoin symptom survey at each visit. Responses were stratified by age group and psychiatric history.

RESULTS

The charts of 102 patients, representing 123 courses of isotretinoin and 760 treatment-months, were reviewed. A total of 722 (95.0%) symptom surveys were complete and 38 (5.0%) were incomplete/missing. Recorded side effects were similar to published adult data; dry lips/dry skin were reported in 94.25% and 72.13% of treatment-months of isotretinoin, respectively. Psychiatric symptoms were reported in 1.65%, with no statistical difference between patients with or without a mental health history. Patients aged 11 to 15 years had similar side-effect profiles to those aged 16 to 21 years. Impaired night vision, nosebleeds, and dry/bloodshot eyes were more common in the older age group.

LIMITATIONS

This was a retrospective chart review, with known limitations. The study was performed at a tertiary referral center for pediatric dermatology, possibly allowing patient selection bias.

CONCLUSIONS

The isotretinoin symptom survey appears to be an effective screening tool to standardize monitoring of isotretinoin side effects in the pediatric population.

Efficacy and safety of acnecutan for acne treatment

Acnecutan represents an innovative form of isotretinoin, having bioavailability The aim of our study was to evaluate safety and clinical efficacy of the drug isotretinoin (Acnecutan) in the treatment of patients with acne of medium-severe and severe. The treatment of 56 patients with acne, until the exchange rate dose of 100-120 mg/kg. The clinical results of the drug Acnecutan indicate a high level of safety and tolerability

[Treatment of acne in daily clinical practice: an opinion poll among Spanish dermatologists]

BACKGROUND AND OBJECTIVES

the aim of this study was to determine the approaches used to treat acne in clinical practice by Spanish dermatologists. A secondary objective of the study was to compare the practices of Spanish dermatologists with the Acne Global Alliance treatment algorithm and develop a Spanish treatment algorithm for acne.

PATIENTS AND METHODS

a multicenter, cross-sectional survey was undertaken among 872 Spanish dermatologists. The study comprised 4 randomly distributed questionnaires. The first 3 contained the following case descriptions: severe acne associated with masculinization (case 1), mild comedonal acne (case 2), and moderate papulopustular acne (case 3). The fourth questionnaire contained 5 photographs of different types of acne and an algorithm containing various treatment options, from which dermatologists were asked to choose the most appropriate.

RESULTS

for case 1, 55% of dermatologists chose oral antiandrogens/contraceptive drugs plus topical retinoids or topical benzoyl peroxide/antibiotics. In case 2, 62% chose topical retinoids and, in case 3, 68% chose systemic antibiotics plus benzoyl peroxide. Combination therapy was considered the treatment of choice in all types of acne, with topical retinoids as the initial treatment option for mild and moderate forms and the preferred option for maintenance therapy.

CONCLUSIONS

in general, Spanish dermatologists treat acne in accordance with the Acne Global Alliance treatment algorithm. The varying opinions reported in response to open questions, however, confirm the need to unify criteria for the treatment of acne.

Changing the topography of acne with topical medications

PURPOSE OF REVIEW

Acne vulgaris is a common skin condition that affects approximately 40-50 million Americans annually. The peak incidence of acne occurs during adolescence and young adulthood, with approximately 80% of persons aged 11-30 years having at least minor acne. Because the onset of acne is typically in early adolescence, pediatricians are often at the front-lines in terms of caring for patients with this chief complaint.

RECENT FINDINGS

Over the last 2 years, new acne therapies have become available. These include new combination fixed-dose products, which may allow for greater flexibility in treatment and greater patient compliance. New topical antibiotics have also come to the market, providing more therapeutic options for mild to moderate inflammatory acne. Lastly, acne therapies involving the use of light sources and photosensitizers are currently being developed, which may provide a whole new modality for managing complicated patients.

SUMMARY

Successful management of acne requires the physician to make a thorough assessment of the patient's acne severity, predominant lesion type, skin type, and lifestyle in order to pair each individual patient's needs with the appropriate anti-acne therapy. This article provides an overview of the pathophysiology of acne and pre-existing topical therapies. It then discusses some novel acne therapies and outlines how they might fit into a physician's treatment strategy.
