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

Clinical and cost-effectiveness of spironolactone in treating persistent facial acne in women: SAFA double-blinded RCT

Background

Acne is common, can cause significant impact on quality of life and is a frequent reason for long-term antibiotic use. Spironolactone has been prescribed for acne in women for many years, but robust evidence is lacking.

Objective

To evaluate whether spironolactone is clinically effective and cost-effective in treating acne in women.

Design

Pragmatic, parallel, double-blind, randomised superiority trial.

Setting

Primary and secondary healthcare and community settings (community and social media advertising).

Participants

Women aged 18 years and older with facial acne persisting for at least 6 months, judged to potentially warrant oral antibiotic treatment.

Interventions

Participants were randomised 1 : 1, using an independent web-based procedure, to either 50 mg/day spironolactone or matched placebo until week 6, increasing to 100 mg/day spironolactone or matched placebo until week 24. Participants continued usual topical treatment.

Main outcome measures

Primary outcome was the adjusted mean difference in Acne-Specific Quality of Life symptom subscale score at 12 weeks. Secondary outcomes included Acne-Specific Quality of Life total and subscales; participant self-assessed improvement; Investigator's Global Assessment; Participant's Global Assessment; satisfaction; adverse effects and cost-effectiveness.

Results

Of 1267 women assessed for eligibility, 410 were randomised (201 intervention, 209 control), 342 in the primary analysis (176 intervention, 166 control). Mean age was 29.2 years (standard deviation 7.2) and 7.9% (28/356) were from non-white backgrounds. At baseline, Investigator's Global Assessment classified acne as mild in 46%, moderate in 40% and severe in 13%. At baseline, 82.9% were using topical treatments. Over 95% of participants in both groups tolerated the treatment and increased their dose. Mean baseline Acne-Specific Quality of Life symptom subscale was 13.0 (standard deviation 4.7) across both groups. Mean scores at week 12 were 19.2 (standard deviation 6.1) for spironolactone and 17.8 (standard deviation 5.6) for placebo [difference favouring spironolactone 1.27 (95% confidence interval 0.07 to 2.46) adjusting for baseline variables]. Mean scores at week 24 were 21.2 (standard deviation 5.9) in spironolactone group and 17.4 (standard deviation 5.8) in placebo group [adjusted difference 3.77 (95% confidence interval 2.50 to 5.03) adjusted]. Secondary outcomes also favoured spironolactone at 12 weeks with greater differences at 24 weeks. Participants taking spironolactone were more likely than those taking placebo to report overall acne improvement at 12 weeks {72.2% vs. 67.9% [adjusted odds ratio 1.16 (95% confidence interval 0.70 to 1.91)]} and at 24 weeks {81.9% vs. 63.3% [adjusted odds ratio 2.72 (95% confidence interval 1.50 to 4.93)]}. Investigator's Global Assessment was judged successful at week 12 for 31/201 (18.5%) taking spironolactone and 9/209 (5.6%) taking placebo [adjusted odds ratio 5.18 (95% confidence interval 2.18 to 12.28)]. Satisfaction with treatment improved in 70.6% of participants taking spironolactone compared with 43.1% taking placebo [adjusted odds ratio 3.12 (95% confidence interval 1.80 to 5.41)]. Adverse reactions were similar between groups, but headaches were reported more commonly on spironolactone (20.4% vs. 12.0%). No serious adverse reactions were reported. Taking account for missing data through multiple imputation gave an incremental cost per quality-adjusted life-year of £27,879 (adjusted) compared to placebo or £2683 per quality-adjusted life-year compared to oral antibiotics.

Conclusions

Spironolactone resulted in better participant-reported and investigator-reported outcomes than placebo, with greater differences at week 24 than week 12.

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.

Mechanisms of probiotic modulation of ovarian sex hormone production and metabolism: a review

Sex hormones play a pivotal role in the growth and development of the skeletal, neurological, and reproductive systems. In women, the dysregulation of sex hormones can result in various health complications such as acne, hirsutism, and irregular menstruation. One of the most prevalent diseases associated with excess androgens is polycystic ovary syndrome with a hyperandrogenic phenotype. Probiotics have shown the potential to enhance the secretion of ovarian sex hormones. However, the underlying mechanism of action remains unclear. Furthermore, comprehensive reviews detailing how probiotics modulate ovarian sex hormones are scarce. This review seeks to shed light on the potential mechanisms through which probiotics influence the production of ovarian sex hormones. The role of probiotics across various biological axes, including the gut-ovarian, gut-brain-ovarian, gut-liver-ovarian, gut-pancreas-ovarian, and gut-fat-ovarian axes, with a focus on the direct impact of probiotics on the ovaries via the gut and their effects on brain gonadotropins is discussed. It is also proposed herein that probiotics can significantly influence the onset, progression, and complications of ovarian sex hormone abnormalities. In addition, this review provides a theoretical basis for the therapeutic application of probiotics in managing sex hormone-related health conditions.

Quartic CAR-T Cell Bridging to Twice Allo-HSCT Therapy in a Patient with Acute Lymphoblastic Leukemia

Introduction

Chimeric antigen receptor T (CAR-T) cell therapy is an effective bridging treatment for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in relapsed or refractory acute lymphoblastic leukemia (ALL). However, repetitive CAR-T cell therapy and allo-HSCT can only be performed in a few patients because of technical difficulties and patients' physical, economic, and social conditions.

Case Presentation

A 23-year-old female patient with second relapsed B-cell ALL (B-ALL) underwent human-murine chimeric CD19 CAR-T cell therapy twice, human-murine chimeric CD22 CAR-T cell therapy once, and humanized CD19 CAR-T cell therapy once. Moreover, she was sequentially bridged to her mother donor allo-HSCT once and cousin donor allo-HSCT once.

Conclusion

Repetitive CAR-T cell therapy bridging to repetitive allo-HSCT is still a safe and active therapeutic strategy for patients with relapsed or refractory ALL.

Eradication of CD48-positive tumors by selectively enhanced YTS cells harnessing the lncRNA NeST

Natural killer (NK) cells are currently used in clinical trials to treat tumors. However, such therapies still suffer from problems such as donor variability, reproducibility, and more, which prevent a wider use of NK cells therapeutics. Here we show a potential immunotherapy combining NK cell-mediated tumor eradiation and long non-coding (lnc) RNAs. We overexpressed the interferon (IFN) γ secretion-enhancing lncRNA nettoie Salmonella pas Theiler's (NeST) in the NK cell-like cell line YTS. YTS cells express the co-stimulatory receptor 2B4 whose main ligand is CD48. On YTS cells, 2B4 functions by direct activation. We showed that NeST overexpression in YTS cells resulted in increased IFNγ release upon interaction with CD48 (selectively enhanced (se)YTS cells). Following irradiation, the seYTS cells lost proliferation capacity but were still able to maintain their killing and IFNγ secretion capacities. Finally, we demonstrated that irradiated seYTS inhibit tumor growth in vivo. Thus, we propose seYTS cells as off-the-shelve therapy for CD48-expressing tumors.

Androgen Receptor Inhibitors in the Treatment of Acne Vulgaris: Efficacy and Safety Profiles of Clascoterone 1% Cream

The purpose of this narrative review is to provide a summary of the clinical trials on the efficacy and safety of clascoterone 1% cream (Winlevi) to grant providers an understanding of which patients will benefit most from this novel topical antiandrogen medication. Clascoterone 1% cream (Winlevi) offers a new and exciting treatment approach for a difficult and common skin condition such as acne vulgaris. This topical androgen antagonist is the first of its kind but will hopefully provoke investigations into other androgen receptor antagonists with similar or better efficacy.

What is new in adult acne for the last 2 years: focus on acne pathophysiology and treatments

Acne affects more than 640 million people worldwide, including about 85% of adolescents. This inflammatory dermatosis affects the entire population, from teenagers to adults, which reinforces the need to investigate it. Furthermore, in adults, acne has serious consequences, including a psychological impact, low self-esteem, social isolation, and depression. Over the last years, the understanding of acne pathophysiology has improved, mainly thanks to the identification of the pivotal role of the microbiota. The aim of this review was to screen the most recent scientific literature on adult acne and the newly tested treatments. Clinically, therapeutic innovations for the treatment of acne have been recently developed, including pre/probiotics, new molecules, and innovative formulations associated, however, with fewer side effects. Moreover, clinical trials are underway to use off-label molecules that seem to be proving their value in the fight against adult acne.

What the Pediatric and Adolescent Gynecology Clinician Needs to Know about Acne

Acne vulgaris is a common skin condition encountered in specialties outside of dermatology, including obstetrics and gynecology. The pathophysiology of acne is complex and includes disruption of the cutaneous microbiome, abnormal keratinization, inflammation, and hormonal influences. Various topical and systemic treatment modalities target each component of acne pathophysiology. Clinically, acne can be broken down into noninflammatory, inflammatory, or mixed subtypes. The age of the patient at presentation and signs and symptoms of hormonal imbalance might prompt workup for underlying disorders. The severity as well as type of acne dictates the type of treatment.

Androgens and acne: perspectives on clascoterone, the first topical androgen receptor antagonist

Introduction: Increased circulating androgens are key to the multifactorial pathogenesis of acne. Clascoterone is the first topical androgen antagonist developed to treat acne in both male and female patients and the first such agent to receive U.S. Food and Drug Administration (FDA) approval for treatment of acne. Androgens directly stimulate sebaceous gland growth and increased sebum production, creating a nourishing medium in which anaerobic Cutibacterium acnes (C. acnes) bacteria flourish. Androgens may directly contribute to inflammation in the sebaceous gland.Areas covered: In this review, the author assesses clascoterone's potential role in the management of acne. With a 4-ring backbone identical to dihydrotestosterone (DHT) and spironolactone, topically applied clascoterone binds androgen receptors (ARs) in the sebaceous glands and hair follicles, interfering with the pathogenesis of acne and reducing acne lesions with no reported systemic effects.Expert opinion: Phase III study results confirmed the safety and efficacy of topical clascoterone for acne, with considerable reductions in absolute non-inflammatory and inflammatory lesion counts at week 12. The approval of a first-in-class topical androgen antagonist is indeed a 'game-changer' for acne management. This topical agent is expected to be quickly adopted in clinical practice, likely within combination regiments, yet to be formally evaluated.

Long-term use of spironolactone for acne in women: A case series of 403 patients

BACKGROUND

There are limited data regarding the long-term outcomes of spironolactone use for women with acne and its effect on truncal acne.

OBJECTIVE

To comprehensively describe outcomes of patients treated with spironolactone in routine clinical practice, including long-term outcomes.

METHODS

We performed a retrospective case series of 403 adult women treated for acne with spironolactone at an academic medical center between 2008 and 2019. Rates of objective, as assessed by Comprehensive Acne Severity Scale scores, and subjective acne clearance were evaluated, as well as rates of treatment discontinuation, dosage changes, and drug survival. Logistic regression was used to assess for association between incidence of menstrual adverse effects and combined oral contraceptive use.

RESULTS

As evaluated by Comprehensive Acne Severity Scale scores, at the first follow-up, 75.5%, 84.0%, and 80.2% of patients with available data had reduction or complete clearance of acne on the face, chest, and back, respectively. The mean drug survival was 470.7 days. Menstrual adverse effects were less common among those using combined oral contraception (odds ratio, 0.23; 95% confidence interval, 0.11-0.50).

LIMITATIONS

This study was conducted at a single academic medical center.

CONCLUSIONS

Spironolactone improves clinical outcomes and is well tolerated for many adult women with acne using it for an extended duration.

Use of spironolactone to treat acne in adolescent females

BACKGROUND/OBJECTIVES

Studies assessing the utility of spironolactone for treating acne in adolescent females are lacking. Thus, we sought to examine spironolactone's role in treating this patient population.

METHODS

A retrospective review was performed to determine the efficacy of spironolactone treatment in adolescent females seen at Mayo Clinic in Rochester, Minnesota, from 2007 to 2017.

RESULTS

In a cohort of 80 pediatric patients with a median age of 19 years (range, 14-20 years), 64 patients (80%) experienced improvement of acne on treatment with spironolactone (median dose, 100 mg daily) with a favorable side effect profile. Approximately a quarter of patients (22.5%) had a complete response; more than half (58.8%) had a complete response or a partial response greater than 50%. Initial and maximal responses were observed at a median of 3 months and 5 months, respectively. Patients received treatment with spironolactone for a median duration of 7 months (range, 3-45 months) with limited side effects.

CONCLUSIONS

Spironolactone demonstrated efficacy in treating acne in adolescent females and is a safe long-term alternative to systemic antibiotics in these patients.

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.

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.
