Is hormonal treatment still an option in acne today?

The impact of using the levonorgestrel-releasing intrauterine device on the incidence of acne in adolescents and young women

PURPOSE

To evaluate the impact of levonorgestrel-releasing intrauterine device (LNG-IUD) use on the incidence of acne in adolescents and young women.

METHODS

A narrative review was conducted in PubMed, Embase, Cochrane, and SciELO assessing the incidence of acne in adolescents and young women using LNG-IUD (13.5, or 19.5 mg, or 52 mg). Cohort, cross-sectional studies, clinical trials, and meta-analyses were included, without a date limit. Studies that didn't evaluate women in the age of interest were excluded. Only articles in English were selected.

RESULTS

Nine articles were included in this narrative review. Only clinical trials, cohort studies, and cross-sectional studies were evaluated. Two cross-sectional studies evaluated the incidence of acne in women using any contraceptive methods, with the incidence of acne being 36% in women aged 17 to 47 using LNG-IUD in one study. In another study, acne incidence ranged from 2 to 8% in women using any contraceptive methods, with higher rates in younger women and LNG-IUD users. The incidence of acne varies and participants between 16 to 35 years were more likely to report new acne or worsening of pre-existing acne. In a prospective cohort study of women between 16 and 24 years, acne was a common adverse effect, with 44% in the first year.

CONCLUSION

The data indicate variability in the incidence of acne among LNG-IUD users, with a higher prevalence observed in younger women. Further research should focus on the effects of LNG-IUD on acne in young populations, with rigorous study designs and consideration of previous contraceptive use.

Isotretinoin-unresponsive acne as a sign of a congenital disorder: a case of 21-hydroxylase deficiency

Acne is a multifactorial and common disorder among young people and a frequent reason for dermatology consultation. When moderate-to-severe acne is not responsive to conventional treatments, oral isotretinoin is a very effective solution. However, there are cases in which this treatment fails to produce the expected results. In this case, an 18-year-old male patient with acne, unresponsive to traditional acne therapies, experienced only a partial benefit from oral isotretinoin. Endocrinology consultation and hormonal work-up revealed androgen metabolism anomalies suggestive of a non-classical form of congenital adrenal hyperplasia due to 21-hydroxylase deficiency. In this case report, the authors discuss when to suspect, how to diagnose, and how to manage similar cases.

Emerging Insights into the Applicability of Essential Oils in the Management of Acne Vulgaris

The occurrence of pustules, comedones, nodules, and cysts defines acne vulgaris, a prevalent chronic inflammatory dermatological condition. In the past few decades, essential oils extracted from varied natural sources have acquired recognition due to their potential medicinal applications in acne therapy. However, there is not yet sufficient medical data to fully characterize this interaction. Multiple factors contribute to the development of acne vulgaris, including excessive sebaceous production, inflammatory processes, hyperkeratinization, and infection with Cutibacterium acnes. Essential oils, including oregano, lavender, lemon grass, myrtle, lemon, thyme, eucalyptus, rosemary, and tea tree, have been found to possess anti-inflammatory, antioxidant, and antimicrobial properties, which may target the multifactorial causes of acne. Analytical methods for determining antioxidant potential (i.e., total phenolic content, diphenyl-1-picrylhydrazyl free radical scavenging assay, reducing power assay, ferrous ion chelating activity, thiobarbituric acid reactive species assay, β-carotene bleaching assay, etc.) are essential for the evaluation of these essential oils, and their method optimization is crucial. Further studies could include the development of novel acne treatments incorporating essential oils and an assessment of their efficacy in large clinical trials. In addition, further research is necessary to ascertain the mechanisms of action of essential oils and their optimal doses and safety profiles for optimal implementation in the management of acne vulgaris.

Herbal Arsenal against Skin Ailments: A Review Supported by In Silico Molecular Docking Studies

Maintaining healthy skin is important for a healthy body. At present, skin diseases are numerous, representing a major health problem affecting all ages from neonates to the elderly worldwide. Many people may develop diseases that affect the skin, including cancer, herpes, and cellulitis. Long-term conventional treatment creates complicated disorders in vital organs of the body. It also imposes socioeconomic burdens on patients. Natural treatment is cheap and claimed to be safe. The use of plants is as old as mankind. Many medicinal plants and their parts are frequently used to treat these diseases, and they are also suitable raw materials for the production of new synthetic agents. A review of some plant families, viz., Fabaceae, Asteraceae, Lamiaceae, etc., used in the treatment of skin diseases is provided with their most common compounds and in silico studies that summarize the recent data that have been collected in this area.

Challenges in treatment of patients with non-classic congenital adrenal hyperplasia

Congenital adrenal hyperplasia (CAH) due to 21α-hydroxylase deficiency (21OHD) or 11β-hydroxylase deficiency (11OHD) are congenital conditions with affected adrenal steroidogenesis. Patients with classic 21OHD and 11OHD have a (nearly) complete enzyme deficiency resulting in impaired cortisol synthesis. Elevated precursor steroids are shunted into the unaffected adrenal androgen synthesis pathway leading to elevated adrenal androgen concentrations in these patients. Classic patients are treated with glucocorticoid substitution to compensate for the low cortisol levels and to decrease elevated adrenal androgens levels via negative feedback on the pituitary gland. On the contrary, non-classic CAH (NCCAH) patients have more residual enzymatic activity and do generally not suffer from clinically relevant glucocorticoid deficiency. However, these patients may develop symptoms due to elevated adrenal androgen levels, which are most often less elevated compared to classic patients. Although glucocorticoid treatment can lower adrenal androgen production, the supraphysiological dosages also may have a negative impact on the cardiovascular system and bone health. Therefore, the benefit of glucocorticoid treatment is questionable. An individualized treatment plan is desirable as patients can present with various symptoms or may be asymptomatic. In this review, we discuss the advantages and disadvantages of different treatment options used in patients with NCCAH due to 21OHD and 11OHD.

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.

Updated Treatment for Acne: Targeted Therapy Based on Pathogenesis

Previous approaches to acne management have focused on the four main factors implicated in acne, namely, androgen-mediated sebogenesis (considered integral to acne), hyperkeratinization, colonization with Cutibacterium acnes, and inflammation related to both innate and adaptive mechanisms. Recent advances have facilitated potential novel approaches to acne management, as the pathophysiology and the immunological aspects related to acne and wound healing have evolved. Particular targets that have been shown to be closely involved in acne pathophysiology and wound healing include interleukin (IL)-1β, IL-17, IL-23, and tumor necrosis factor alpha (TNFα). Biological antibodies targeting IL-1β, IL-17, IL-23, and TNFα could provide novel approaches for treating severe acne and related disorders. Acne is primarily a disease associated with sebogenesis. Monosaturated free acids are important components. Insulin growth factor 1 (IGF-1) promotes the proliferation and differentiation of sebocytes and IL-1β. Research into the microbiome may also provide insights into potential future therapeutic options for acne. Scars, both atrophic and hypertrophic, are common sequelae to acne. Risk factors associated with the development of acne scars include genetic, systemic, local, and lifestyle factors. Pro-inflammatory cytokines have been shown to play a crucial role in the development of acne-induced hypertrophic scars. Treatment for extensive inflammatory keloid scarring is limited. Surgery and postoperative radiotherapy are two possible options. Transforming growth factor-β (TGFβ), IL-6, matrix metalloproteinase (MMP), IGF-1, and B cells are found in keloid or hypertrophic scar tissues. Biological antibodies targeting these cytokines may be a potential strategy for the prevention and treatment of this type of scar in the future. Future treatment for acne should embrace approaches that target the main etiological factors of acne. In particular, specific emphasis on aggressive treatment in the acute inflammatory phase to reduce the likelihood of scarring and other clinical sequelae, such as pigmentary changes would be highly desirable. Treatment for established acne-induced sequelae should also be considered.

Acne in the first three decades of life: An update of a disorder with profound implications for all decades of life

Acne vulgaris is a chronic, inflammatory, skin condition that involves the pilosebaceous follicles and is influenced by a variety of factors including genetics, androgen-stimulation of sebaceous glands with abnormal keratinization, colonization with Cutibacterium acnes (previously called Propionibacterium acnes), and pathological immune response to inflammation. Acne can occur at all ages and this discussion focuses on the first three decades of life. Conditions that are part of the differential diagnosis and/or are co-morbid with acne vulgaris are also considered. Acne in the first year of life includes neonatal acne (acne neonatorum) that presents in the first four weeks of life and infantile acne that usually presents between 3 and 6 months of the first year of life with a range of 3 to 16 months after birth. Acne rosacea is a chronic, inflammatory, skin condition that is distinct from acne vulgaris, typically presents in adults, and has four main types: erythemato-telangiectatic, papulopustular, phymatous and ocular. Treatment options for acne vulgaris include topical retinoids, topical benzoyl peroxide, antibiotics (topical, oral), oral contraceptive pills, isotretinoin, and others. Management must consider the increasing impact of antibiotic resistance in the 21st century. Psychological impact of acne can be quite severe and treatment of acne includes awareness of the potential emotional toll this disease may bring to the person with acne as well as assiduous attention to known side effects of various anti-acne medications (topical and systemic). Efforts should be directed at preventing acne-caused scars and depigmentation on the skin as well as emotional scars within the person suffering from acne.

Androgens in women: Androgen-mediated skin disease and patient evaluation

Androgens are produced throughout the body in steroid-producing organs, such as the adrenal glands and ovaries, and in other tissues, like the skin. Several androgens are found normally in women, including dehydroepiandrosterone, dehydroepiandrosterone-sulfate, testosterone, dihydrotestosterone, and androstenedione. These androgens are essential in the development of several common cutaneous conditions in women, including acne, hirsutism, and female pattern hair loss (FPHL)-androgen-mediated cutaneous disorders (AMCDs). However, the role of androgens in the pathophysiology of these diseases is complicated and incompletely understood. In the first article in this Continuing Medical Education series, we discuss the role of the skin in androgen production and the impact of androgens on the skin in women. Specifically, we review the necessary but insufficient role that androgens play in the development of acne, hirsutism, and FPHL in women. Dermatologists face the challenge of differentiating physiologic from pathologic presentations of AMCDs in women. There are currently no dermatology guidelines outlining the indications for endocrinologic evaluation in women presenting with acne, hirsutism, or FPHL. We review the available evidence regarding when to consider an endocrinologic workup in women presenting with AMCDs, including the appropriate type and timing of testing.

Androgens in women: Hormone-modulating therapies for skin disease

Androgen-mediated cutaneous disorders (AMCDs) in women, including acne, hirsutism, and female pattern hair loss, can be treated with hormone-modulating therapies. In the second article in this Continuing Medical Education series, we discuss the hormone-modulating therapies available to dermatologists for the treatment of AMCDs, including combined oral contraceptives, spironolactone, finasteride, dutasteride, and flutamide. Available hormone-modulating treatments used for each AMCDs are reviewed, along with mechanisms of androgen modulation, safety profile, contraindications, monitoring parameters, and evidence of efficacy. Medications discussed include those that are approved by the US Food and Drug Administration for certain AMCDs and some that are used off-label. Despite the ubiquity of hormone-modulating therapies used for AMCDs, this review highlights the need for more rigorous studies to evaluate these therapies for acne, hirsutism, and female pattern hair loss.

The Use of Hormonal Antiandrogen Therapy in Female Patients with Acne: A 10-Year Retrospective Study

BACKGROUND

Little is known about how dermatologists prescribe hormonal antiandrogen acne treatment (HAAT).

OBJECTIVE

The aim of this study was to investigate dermatologists' HAAT-prescribing habits and HAAT's impact on systemic antibiotic use in women with acne.

METHODS

We performed a retrospective study at an academic medical center of female patients receiving HAAT (combined oral contraceptive [COC], spironolactone) for acne from January 2005 to October 2015. Data from a control group of female acne patients who never received HAAT were also collected.

RESULTS

A total of 672 female patients received HAAT. Out of all systemic medications for acne, antibiotics were used as first-line treatment in 39% of patients, COCs in 12%, and spironolactone in 21%. Mean antibiotic durations in patients who initiated HAAT for the first time at the study site (250.4 days) were significantly longer than in patients who received HAAT prior to presentation and continued HAAT at the study site (192.0 days) (p = 0.021). A statistically significant inverse association was found between HAAT use and mean antibiotic duration (p = 0.016).

CONCLUSIONS

HAAT is not typically used as a first-line systemic therapy in women with acne. HAAT usage is associated with shorter cumulative antibiotic durations and early HAAT initiation can decrease systemic antibiotic use in acne treatment.

Algorithm for acne treatment: Ibero-Latin American consensus

Acne is a chronic, immune-mediated, inflammatory disease with high prevalence among adolescents. By compromising face, thorax and back, with the risk of permanent scars, it has a negative impact on the quality of life. Effective, safe and early treatment is the key to remission, while decreasing the risk of physical and/or emotional sequelae. The Iberian-Latin American Group of Acne Studies joined professionals with expertise and developed a practical therapeutic algorithm, adapted to the reality of Latin American countries, Spain and Portugal. This article intends to disseminate it with an updated review on a rational, safe and effective acne treatment.

Clinical behavior of a cohort of adult women with facial acne treated with combined oral contraceptive: ethinylestradiol 20 µg/dienogest 2 mg

Acne vulgaris is the most common skin disease. It affects the young adult female population and generates great impact on physical and mental health. One of the treatments with good results for affected women is combined oral contraceptive pills (COCPs). The aim of this study was to determine the clinical effect of facial acne management with ethinylestradiol 20 µg/dienogest 2 mg in a cohort of Colombian adult women. A cohort of 120 female university students was followed for 12 months. These participants were enrolled in the Sexual and Reproductive Health Program of the Santiago de Cali University. This cohort admitted women between 18 and 30 years old who had chosen to start birth control with ethinylestradiol 20 µg/dienogest 2 mg COCPs, did not have contraindi cations to the use of COCPs, and had been diagnosed with acne. Monthly monitoring of facial acne lesion count was performed. Relative changes in facial lesion count were identified. At the end of follow-up, the percentage of reduction of lesions was 94% and 23% of women had a 100% reduction in acne lesions. In conclusion, the continued use of the ethinylestradiol 20 µg/dienogest 2 mg COCPs reduced inflammatory and non-inflammatory acne lesions in reproductive-age women between 18 and 30 years of age with no severe acne.

Current treatments of acne: Medications, lights, lasers, and a novel 650-μs 1064-nm Nd: YAG laser

The treatment of acne, especially severe acne, remains a challenge to dermatologists. Therapies include retinoids, antibiotics, hormones, lights, lasers, and various combinations of these modalities. Acne is currently considered a chronic rather than an adolescent condition. The appropriate treatment depends on the patient and the severity of disease. The purpose of this study was to review current therapies for acne of all severities and to introduce the 650-μs 1064-nm laser for the treatment of acne.

Oral Spironolactone for Acne Vulgaris in Adult Females: A Hybrid Systematic Review

BACKGROUND

The management of acne in adult females is problematic, with many having a history of treatment failure and some having a predisposition to androgen excess. Alternatives to oral antibiotics and combined oral contraceptives (COCs) are required.

OBJECTIVE

Our aim was to conduct a hybrid systematic review of the evidence for benefits and potential harms of oral spironolactone in the management of acne in adult females.

METHODS

The review was conducted according to a previously published protocol. Three reviewers independently selected relevant studies from the search results, extracted data, assessed the risk of bias, and rated the quality of the evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

RESULTS

Ten randomized controlled trials (RCTs) and 21 case series were retrieved. All trials were assessed as being at a 'high risk' of bias, and the quality of evidence was rated as low or very low for all outcomes. Apart from one crossover trial that demonstrated statistical superiority of a 200 mg daily dose versus inflamed lesions compared with placebo, data from the remaining trials were unhelpful in establishing the degree of efficacy of lower doses versus active comparators or placebo. Menstrual side effects were significantly more common with the 200 mg dose; frequency could be significantly reduced by concomitant use of a COC. Pooling of results for serum potassium supported the recent recommendation that routine monitoring is not required in this patient population.

CONCLUSION

This systematic review of RCTs and case series identified evidence of limited quality to underpin the expert endorsement of spironolactone at the doses typically used (≤100 mg/day) in everyday clinical practice.

Hormonal treatment of acne vulgaris: an update

Acne vulgaris is a common skin condition associated with multiple factors. Although mostly presenting alone, it can likewise present with features of hyperandrogenism and hormonal discrepancies. Of note, hormonal therapies are indicated in severe, resistant-to-treatment cases and in those with monthly flare-ups and when standard therapeutic options are inappropriate. This article serves as an update to hormonal pathogenesis of acne, discusses the basics of endocrinal evaluation for patients with suspected hormonal acne, and provides an overview of the current hormonal treatment options in women.

A consensus-based practical and daily guide for the treatment of acne patients

BACKGROUND

Many current guidelines provide detailed evidence-based recommendations for acne treatment.

OBJECTIVE

To create consensus-based, simple, easy-to-use algorithms for clinical acne treatment in daily office-based practice and to provide checklists to assist in determining why a patient may not have responded to treatment and what action to take.

METHODS

Existing treatment guidelines and consensus papers were reviewed. The information in them was extracted and simplified according to daily clinical practice needs using a consensus-based approach and based on the authors' clinical expertise.

RESULTS

As outcomes, separate simple algorithms are presented for the treatment of predominant comedonal, predominant papulopustular and nodular/conglobate acne. Patients with predominant comedonal acne should initially be treated with a topical retinoid, azelaic acid or salicylic acid. Fixed combination topicals are recommended for patients with predominant papulopustular acne with treatment tailored according to the severity of disease. Treatment recommendations for nodular/conglobate acne include oral isotretinoin or fixed combinations plus oral antibiotics in men, and these options may be supplemented with oral anti-androgenic hormonal therapy in women. Further decisions regarding treatment responses should be evaluated 8 weeks after treatment initiation in patients with predominant comedonal or papulopustular acne and 12 weeks after in those with nodular/conglobate acne. Maintenance therapy with a topical retinoid or azelaic acid should be commenced once a patient is clear or almost clear of their acne to prevent the disease from recurring. The principal explanations for lack of treatment response fall into 5 main categories: disease progression, non-drug-related reasons, drug-related reasons, poor adherence, and adverse events.

CONCLUSION

This practical guide provides dermatologists with treatment algorithms adapted to different clinical features of acne which are simple and easy to use in daily clinical practice. The checklists to establish the causes for a lack of treatment response and subsequent action to take will facilitate successful acne management.

Medicinal Plants for the Treatment of Acne Vulgaris: A Review of Recent Evidences

Context:

Acne vulgaris affects about 85% of teenagers and may continue to adulthood. There are about two million visits to physicians per year for teenagers and the direct cost of acne treatment in the US exceeds $1 billion per year.

Evidence Acquisition:

A wide variety of treatment regimens exist for acne vulgaris including benzoil peroxide, retinoids, isotretinoids, keratolytic soaps, alpha hydroxy acids, azelaic acid, salicilic acid as well as hormonal, anti-androgen or antiseborrheic treatments. However, none of these methods is free of side effects and their exact role in therapy is not clear. In this paper apart from presenting the possible causes of acne vulgaris and its available drugs, recently published papers about medicinal plants used in the treatment of acne vulgaris were reviewed.

Results:

Consumption of alternative and complementary medicine, including medicinal plants, is increasing and is common amongst patients affected by acne and infectious skin diseases. Medicinal plants have a long history of use and have been shown to possess low side effects. These plants are a reliable source for preparation of new drugs.

Conclusions:

Many plants seem to have inhibitory effects on the growth of bacteria, fungi and viruses in vitro. However, there are a few clinical evidences about the effectiveness and safety of these plants in the treatment of acne and other skin infections.
