Prescribing Patterns of Oral Antibiotics and Isotretinoin for Acne in a Colorado Hospital System: Retrospective Cohort Study

BACKGROUND

Guidelines established by the American Academy of Dermatology recommend oral antibiotics as first-line therapy for mild, moderate, and severe acne. However, it is recommended to minimize the duration of oral antibiotic use, and there is increasing support for other systemic agents for acne.

OBJECTIVE

We sought to characterize the use of oral antibiotics and isotretinoin for the treatment of acne in the pediatric and young adult population aged 10 through 20 years and the adult population aged 21 to 45 years from 2011 to 2019.

METHODS

We conducted a retrospective, observational cohort study using electronic data from the enterprise data warehouse of the University of Colorado Anschutz Medical Campus and its affiliates, with data in the format of the Observational Health Data Sciences and Informatics (OHDSI) Observational Medical Outcomes Partnership (OMOP) common data model. Categorical values (sex, race, and ethnicity) were compared using chi-square tests, and continuous variables (age) were compared using 2-tailed t tests.

RESULTS

Our cohort of 15,704 patients was composed of mostly White (12,776/15,704, 81.4%), non-Hispanic or Latino (13,307/15,704, 84.7%), and female (11,093/15,704, 70.6%) patients. Among the 4605 male patients in the eligible cohort, 1810 (39%) received an oral antibiotic treatment, in comparison to 3109 (28%) of the 11,093 eligible women (P<.001). Among the 4605 men who were eligible for treatment with isotretinoin in this population, 988 (21.5%) received a course of isotretinoin, compared to only 10.4% (1159/11,093) eligible women (P<.001). Male patients were 1.67 times more likely to have received an antibiotic prescription (odds ratio [OR] 1.67, 95% CI 1.55-1.79) and over twice as likely to have received an isotretinoin prescription (OR 2.34, 95% CI 2.13-2.57) than female patients.

CONCLUSIONS

Minocycline was the most frequently prescribed antibiotic for the treatment of acne in this study cohort. From 2015 to 2019, there was no significant change in the number of antibiotic prescriptions over time. Men were significantly more likely to receive both oral antibiotics and isotretinoin than female patients. Multiple factors could be contributing to this discrepancy, including the burden of iPLEDGE, additional systemic treatment options for female patients, and the difference in acne severity across sexes. We could not determine the difference in severity of acne between male and female patients in our cohort, and further research is needed to ascertain the variation across sexes.

[Impact of combined oral contraceptives and spironolactone on hirsutism and quality of life]

OBJECTIVES

Combined oral contraceptives (COC) and spironolactone are the first and second-line treatments of mild hirsutism, since the use of cyproterone acetate was restricted to the treatment of severe hirsutism by the French guidelines for hyperandrogenism published in May 2020. Because spironolactone was until now barely used in France, the aim of this study was to evaluate the indication, efficacy and impact on quality of life of COC and spironolactone treatments on mild hirsutism in non-menopausal women.

METHODS

This retrospective monocentric study was conducted between June 2020 and October 2021. It included patients with mild hirsutism who received a prescription of COC or/and spironolactone. Modified Ferriman and Gallwey score (FGm) was performed by clinicians and self-rated by patients during the follow-up. Hirsutism-related quality of life was assessed using the Dermatology Life Quality Index (DLQI) and a visual analog scale.

RESULTS

A total of 44 patients were included, but only 30 patients received the treatment for 6 months. 70% of patients were free of side effects. Clinically we observed a decrease of 26% in the FGm score rated by clinicians and patients after 6 months of treatment (P<0,01). This was not correlated with an improvement in quality of life.

CONCLUSIONS

The data collected showed the clinical efficacy of both COC and spironolactone in the treatment of mild hirsutism. These two treatments were well-tolerated. However, the quality of life scores did not improve after 6 months. These treatments should be evaluated after a longer period.

Effects of Low-Dose Spironolactone Combined with Metformin or Either Drug Alone on Insulin Resistance in Patients with Polycystic Ovary Syndrome: A Pilot Study

Metformin and spironolactone alone can be used for the management of polycystic ovarian syndrome (PCOS), and their combination could result in even better outcomes. To compare the effects and safety of low-dose spironolactone combined with metformin or either drug alone on insulin resistance (IR) and functional improvement in patients with PCOS, this was a single-center, randomized, open-label, pilot study of patients with PCOS at the Third Affiliated Hospital of Guangzhou Medical University between 01/2014 and 01/2016. The participants were randomized 1 : 1 : 1 to metformin, spironolactone, or metformin + spironolactone. The primary endpoint was the change in the homeostatic model assessment (HOMA)-IR after 12 weeks of treatment. A total of 189 participants were randomized (63 per group); 31 dropped out, and 54, 51, and 53 completed the 12-week treatment in the metformin, spironolactone, and combined groups, respectively. There were no differences in any parameters between the metformin and spironolactone groups (all P > 0.05). In the combined group, after 12 weeks of treatment, HOMA-IR (1.71 ± 0.91) was lower than in the metformin (1.92 ± 1.07, P < 0.05) and spironolactone (2.38 ± 1.14, P < 0.05) groups. In addition, total testosterone (TT), free androgen index (FAI), and area under the curve-insulin (AUCins) were lower in the combined group compared with the metformin group (all P < 0.05), while TT, FAI, HOMA-β, fasting plasma glucose, and AUCins were lower in the spironolactone group (all P < 0.05). Both metformin and spironolactone decreased HOMA-IR in patients with PCOS but without differences between the two monotherapies. The combined therapy decreased HOMA-IR to a greater extent than monotherapy.

Beneficial Extracardiac Effects of Cardiovascular Medications

Cardiovascular diseases are the most common cause of death worldwide, with cardiovascular medications being amongst the most common medications prescribed. These medications have diverse effects on the heart, vascular system, as well as other tissues and organ systems. The extra cardiovascular effects have been found to be of use in the treatment of non-cardiovascular diseases and pathologies. Minoxidil is used to manage systemic hypertension with its well-known side effect of hirsutism used to treat alopecia and baldness. Sildenafil was originally investigated as a treatment option for systemic hypertension; however, its side effect of penile erection led to it being widely used for erectile dysfunction. Alpha-1 blockers such as terazosin are indicated to treat systemic hypertension but are more commonly used for benign prostatic hyperplasia and post-traumatic stress disorder. Beta blockers are the mainstay treatment for congestive heart failure and systemic hypertension but have been found useful to help in patients with intention tremors as well as prophylaxis of migraines. Similarly, calcium channel blockers are indicated in medical expulsion therapy for ureteric calculi in addition to their cardiovascular indications. Thiazides are commonly used for treating systemic hypertension and as diuretics. Thiazides can cause hypocalciuria and hypercalcemia. This side effect has led to thiazides being used to treat idiopathic hypercalciuria and associated nephrolithiasis. Spironolactone is commonly utilized in treating heart failure and as a diuretic for edema. It's well described anti-androgen side effects have been used for acne vulgaris and hirsutism in polycystic ovarian syndrome. This review article discusses how the various extracardiovascular effects of commonly used cardiovascular medications are put to use in managing non-cardiovascular conditions.

Pharmacological Approaches to Controlling Cardiometabolic Risk in Women with PCOS

Polycystic ovary syndrome (PCOS) is characterized by elevated androgen production and subclinical changes in cardiovascular and metabolic risk markers. Total cholesterol, high-density lipoprotein (HDL) cholesterol, fasting glucose, and fasting insulin appear to increase specifically in PCOS compared with fertile women. PCOS also confers an increased risk of cardiometabolic disease in later life. Novel biomarkers such as serum’s cholesterol efflux capacity and blood-derived macrophage activation profile may assist in more accurately defining the cardiometabolic risk profile in these women. Aldosterone antagonists, androgen receptor antagonists, 5α-reductase inhibitors, and synthetic progestogens are used to reduce hyperandrogenism. Because increased insulin secretion enhances ovarian androgen production, short-term treatment with metformin and other hypoglycemic agents results in significant weight loss, favorable metabolic changes, and testosterone reduction. The naturally occurring inositols display insulin-sensitizing effects and may be also used in this context because of their safety profile. Combined oral contraceptives represent the drug of choice for correction of androgen-related symptoms. Overall, PCOS management remains focused on specific targets including assessment and treatment of cardiometabolic risk, according to disease phenotypes. While new options are adding to established therapeutic approaches, a sometimes difficult balance between efficacy and safety of available medications has to be found in individual women.

Coexistance of Gynecomastia and Poland Syndrome: Case Report

Coexistence of the Poland syndrome and gynecomastia is a rare condition. Poland syndrome requires soft tissue augmentation of the affected side, whereas gynecomastia necessitates reduction of the breast tissue. To provide symmetry, breast reduction and fat grafting techniques should be combined. We report a 29-year-old male patient with left gynecomastia and right sided Poland syndrome. In order to correct his asymmetry on the anterior chest wall, left breast tissue resection and fat grafting to the right breast were performed. Having these two opposite conditions at the same time and on the same patient makes the deformities look more dramatic than they are separately. Accurate planning and selection of proper techniques enable to provide symmetry in such cases.

Obesity, Hypertrichosis and Sex Steroids: Are these Factors Related to the Pilonidal Sinus Disease?

OBJECTIVES

Pilonidal sinus disease causes chronic inflammation of the skin and subcutaneous fatty tissue, and it commonly localises in the sacrococcygeal region. This study evaluated the effects of hypertrichosis, family history, obesity and sex steroids in 298 patients with pilonidal sinus disease.

METHODS

The medical records of 618 patients treated at the General Surgery Clinic of Malatya State Hospital for primary pilonidal sinus disease between January 2014 and December 2017 were evaluated retrospectively.

RESULTS

Female sex and family histories of pilonidal sinus disease and hypertrichosis were significantly higher in patients with than without hypertrichosis (p=0.030, p=0.035, p<0.001). The mean progesterone level was significantly lower in female patients with hypertrichosis than female patients without hypertrichosis (p=0.003).

CONCLUSION

Being overweight or obese, having an occupation that requires long-time sitting and having a family history predisposed to developing pilonidal sinus disease.

The Utility of Potassium Monitoring in Gender-Diverse Adolescents Taking Spironolactone

CONTEXT

Current guidelines recommend close monitoring of electrolytes in transgender patients using spironolactone given the risk of hyperkalemia from mineralocorticoid antagonism. In patients taking spironolactone for other conditions, the rate of hyperkalemia is low, and the utility of frequent monitoring has been questioned.

OBJECTIVE

We hypothesized that the rate of hyperkalemia in gender-diverse adolescents taking spironolactone is low and, when present, clinically insignificant.

DESIGN AND OUTCOMES

A retrospective chart review of adolescents seen in a specialty gender clinic at a tertiary care pediatric hospital over 10 years identified patients prescribed spironolactone for gender transition. Study outcomes were the incidence of hyperkalemia, defined as serum potassium concentration >5.0 mmol/L, and the relationship between potassium levels and spironolactone dose and duration.

RESULTS

Records were reviewed for 85 subjects with a mean ± SD age of 16.6 ± 1.7 years. There were a total of 269 potassium measurements (80 prior to spironolactone initiation and 189 during spironolactone treatment). Six potassium measurements in five subjects were >5.0 mmol/L, indicating a rate of hyperkalemia of 2.2%. None of the subjects had symptoms of hyperkalemia, and all elevated measurements were normal when repeated. Only one subject discontinued spironolactone after an elevated potassium measurement. There was no relationship between hyperkalemia and spironolactone dose. Potassium measurements decreased with increasing treatment duration.

CONCLUSIONS

Hyperkalemia in patients taking spironolactone for gender transition is rare and when present is transient and asymptomatic. In the absence of other medical comorbidities, routine electrolyte monitoring in this population may be unnecessary.

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.

Long-Term Response of Hirsutism and Other Hyperandrogenic Symptoms to Combination Therapy in Polycystic Ovary Syndrome

BACKGROUND

Polycystic ovary syndrome (PCOS) affects 5%-15% of women and is the most common cause of hirsutism. Data on the time-course of improvement to suppressive therapy and predictors of that response in PCOS are lacking. The objectives of our study are to determine the long-term response and identify predictors of response in PCOS women treated with suppressive therapy, including spironolactone (SPL) + oral contraceptives (OCs).

MATERIALS AND METHODS

Retrospective cross-sectional analysis of 200 women with PCOS (1990 NIH criteria) treated with suppressive therapy in general, and a subgroup of 138 subjects treated with OCP+SPL who had been prospectively included in a biorepository. Main outcome measure included improvement rate per 100 person-month of follow-up for hirsutism, menstrual irregularity and acne measured qualitatively as "feeling better", and changes in the severity of hirsutism quantified by modified Ferriman-Gallwey [mF-G] score.

RESULTS

During a mean follow-up of 34.2 months, 85.1%, 82.7%, and 79.3% of patients reported improvement in hirsutism, menstrual dysfunction, and acne, respectively. The modified Ferriman-Gallwey (mF-G) hirsutism score improved by 59.9%. The net reduction in mF-G score and the percent of patients reporting improvement in hirsutism were greater for OC+SPL than for either drug alone, with no difference in the percent of patients free of adverse effects. Among those treated with OC+SPL (n = 138), the initial mF-G and sex hormone-binding globulin (SHBG) independently predicted successful therapy for hirsutism.

CONCLUSION

There is a high rate of patient satisfaction with suppressive therapy in PCOS. The efficacy of suppressive therapy for hirsutism was greater with OC+SPL than with either drug alone. Successful treatment of hirsutism with combination OC+SPL requires at least 6 months of therapy, with the proportion of satisfied patients continuing to increase with treatment duration. The probability of patient satisfaction with OC+SPL treatment for hirsutism can be predicted by her initial mF-G score or SHBG level.

Treatment Options for Hirsutism: A Systematic Review and Network Meta-Analysis

BACKGROUND

Several pharmacologic treatments for hirsutism are used in practice; however, their relative efficacy is unclear.

METHODS

We searched MEDLINE, EMBASE, and CENTRAL through January 2017 for randomized controlled trials (RCTs) with follow-up of at least 6 months that evaluated antiandrogens, insulin sensitizers, and oral contraceptives in women with hirsutism. Independent pairs of reviewers selected and appraised trials. Random-effects network meta-analysis was used to compare individual drugs and classes.

RESULTS

We included 43 trials. Estrogen-progestin oral contraceptives pills (OCPs), antiandrogens, and insulin sensitizers were superior to placebo, with standardized mean reductions (95% confidence intervals) of -0.94 (-1.49 to -0.38), -1.29 (-1.80 to -0.79), and -0.62 (-1.00 to -0.23), respectively. Antiandrogen monotherapy, the combination of OCP and antiandrogen, the combination of OCPs and insulin sensitizer, and the combination of antiandrogen and insulin sensitizer were superior to insulin sensitizer monotherapy. The combination of OCPs and antiandrogen was superior to OCPs. Antiandrogen monotherapy with flutamide, finasteride, and spironolactone were each superior to placebo but similar to each other in efficacy. OCPs containing levonorgestrel, cyproterone acetate, or drospirenone were similar in effectiveness to other OCPs or had trivial differences. The certainty in comparisons with placebo was moderate and for head-to-head comparisons was low.

CONCLUSIONS

Estrogen-progestin OCPs, antiandrogens, and insulin sensitizers are superior to placebo for the treatment of hirsutism.

Synchronizing Pharmacotherapy in Acne with Review of Clinical Care

Acne is a chronic inflammatory skin disease that involves the pathogenesis of four major factors, such as androgen-induced increased sebum secretion, altered keratinization, colonization of Propionibacterium acnes, and inflammation. Several acne mono-treatment and combination treatment regimens are available and prescribed in the Indian market, ranging from retinoids, benzoyl peroxide (BPO), anti-infectives, and other miscellaneous agents. Although standard guidelines and recommendations overview the management of mild, moderate, and severe acne, relevance and positioning of each category of pharmacotherapy available in Indian market are still unexplained. The present article discusses the available topical and oral acne therapies and the challenges associated with the overall management of acne in India and suggestions and recommendations by the Indian dermatologists. The experts opined that among topical therapies, the combination therapies are preferred over monotherapy due to associated lower efficacy, poor tolerability, safety issues, adverse effects, and emerging bacterial resistance. Retinoids are preferred in comedonal acne and as maintenance therapy. In case of poor response, combination therapies BPO-retinoid or retinoid-antibacterials in papulopustular acne and retinoid-BPO or BPO-antibacterials in pustular-nodular acne are recommended. Oral agents are generally recommended for severe acne. Low-dose retinoids are economical and have better patient acceptance. Antibiotics should be prescribed till the inflammation is clinically visible. Antiandrogen therapy should be given to women with high androgen levels and are added to regimen to regularize the menstrual cycle. In late-onset hyperandrogenism, oral corticosteroids should be used. The experts recommended that an early initiation of therapy is directly proportional to effective therapeutic outcomes and prevent complications.

Spironolactone for the treatment of acne in women, a retrospective study of 110 patients

BACKGROUND

There is limited evidence on the safety and efficacy of spironolactone in the treatment of women with acne. Thus, for many dermatologists spironolactone remains an alternative rather than a mainstay treatment for female patients with acne.

METHODS

An electronic medical records search tool was used to select data from a group of women who received spironolactone to treat acne and were evaluated with the comprehensive acne severity scale (CASS) before treatment and at all follow-up visits. Data points were collected for CASS scores at each follow-up visit, concurrent and previous treatments, and side effects. These data points were used to draw conclusions about the safety and efficacy of spironolactone in this patient population.

RESULTS

There were 110 patients that met all eligibility requirements. Of these, 94 patients saw an improvement in their CASS score and 61 patients completely cleared their score to 0. There were 16 patients who did not improve and six who relapsed after initial improvement. The women saw an average improvement in their acne by 73.1% for the face, 75.9% for the chest, and 77.6% for the back. Fifty-one women experienced side effects, but only six found them bothersome enough to stop taking spironolactone.

CONCLUSION

A majority of women in this study saw a dramatic improvement in their acne while treated with spironolactone. There were low rates of relapse or discontinuation of the medication. To further promote the use of spironolactone as a first-line systemic treatment for women with acne, there must be more prospective controlled trials.

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.

Interventions for hirsutism (excluding laser and photoepilation therapy alone)

BACKGROUND

Hirsutism occurs in 5% to 10% of women of reproductive age when there is excessive terminal hair growth in androgen-sensitive areas (male pattern). It is a distressing disorder with a major impact on quality of life. The most common cause is polycystic ovary syndrome. There are many treatment options, but it is not clear which are most effective.

OBJECTIVES

To assess the effects of interventions (except laser and light-based therapies alone) for hirsutism.

SEARCH METHODS

We searched the Cochrane Skin Group Specialised Register, CENTRAL (2014, Issue 6), MEDLINE (from 1946), EMBASE (from 1974), and five trials registers, and checked reference lists of included studies for additional trials. The last search was in June 2014.

SELECTION CRITERIA

Randomised controlled trials (RCTs) in hirsute women with polycystic ovary syndrome, idiopathic hirsutism, or idiopathic hyperandrogenism.

DATA COLLECTION AND ANALYSIS

Two independent authors carried out study selection, data extraction, 'Risk of bias' assessment, and analyses.

MAIN RESULTS

We included 157 studies (sample size 30 to 80) comprising 10,550 women (mean age 25 years). The majority of studies (123/157) were 'high', 30 'unclear', and four 'low' risk of bias. Lack of blinding was the most frequent source of bias. Treatment duration was six to 12 months. Forty-eight studies provided no usable or retrievable data, i.e. lack of separate data for hirsute women, conference proceedings, and losses to follow-up above 40%.Primary outcomes, 'participant-reported improvement of hirsutism' and 'change in health-related quality of life', were addressed in few studies, and adverse events in only half. In most comparisons there was insufficient evidence to determine if the number of reported adverse events differed. These included known adverse events: gastrointestinal discomfort, breast tenderness, reduced libido, dry skin (flutamide and finasteride); irregular bleeding (spironolactone); nausea, diarrhoea, bloating (metformin); hot flushes, decreased libido, vaginal dryness, headaches (gonadotropin-releasing hormone (GnRH) analogues)).Clinician's evaluation of hirsutism and change in androgen levels were addressed in most comparisons, change in body mass index (BMI) and improvement of other clinical signs of hyperandrogenism in one-third of studies.The quality of evidence was moderate to very low for most outcomes.There was low quality evidence for the effect of two oral contraceptive pills (OCPs) (ethinyl estradiol + cyproterone acetate versus ethinyl estradiol + desogestrel) on change from baseline of Ferriman-Gallwey scores. The mean difference (MD) was -1.84 (95% confidence interval (CI) -3.86 to 0.18).There was very low quality evidence that flutamide 250 mg, twice daily, reduced Ferriman-Gallwey scores more effectively than placebo (MD -7.60, 95% CI -10.53 to -4.67 and MD -7.20, 95% CI -10.15 to -4.25). Participants' evaluations in one study with 20 participants confirmed these results (risk ratio (RR) 17.00, 95% CI 1.11 to 259.87).Spironolactone 100 mg daily was more effective than placebo in reducing Ferriman-Gallwey scores (MD -7.69, 95% CI -10.12 to -5.26) (low quality evidence). It showed similar effectiveness to flutamide in two studies (MD -1.90, 95% CI -5.01 to 1.21 and MD 0.49, 95% CI -1.99 to 2.97) (very low quality evidence), as well as to finasteride in two studies (MD 1.49, 95% CI -0.58 to 3.56 and MD 0.40, 95% CI -1.18 to 1.98) (low quality evidence).Although there was very low quality evidence of a difference in reduction of Ferriman-Gallwey scores for finasteride 5 mg to 7.5 mg daily versus placebo (MD -5.73, 95% CI -6.87 to -4.58), it was unlikely it was clinically meaningful. These results were reinforced by participants' assessments (RR 2.06, 95% CI 0.99 to 4.29 and RR 11.00, 95% CI 0.69 to 175.86). However, finasteride showed inconsistent results in comparisons with other treatments, and no firm conclusions could be reached.Metformin demonstrated no benefit over placebo in reduction of Ferriman-Gallwey scores (MD 0.05, 95% CI -1.02 to 1.12), but the quality of evidence was low. Results regarding the effectiveness of GnRH analogues were inconsistent, varying from minimal to important improvements.We were unable to pool data for OCPs with cyproterone acetate 20 mg to 100 mg due to clinical and methodological heterogeneity between studies. However, addition of cyproterone acetate to OCPs provided greater reductions in Ferriman-Gallwey scores.Two studies, comparing finasteride 5 mg and spironolactone 100 mg, did not show differences in participant assessments and reduction of Ferriman-Gallwey scores (low quality evidence). Ferriman-Gallwey scores from three studies comparing flutamide versus metformin could not be pooled (I² = 62%). One study comparing flutamide 250 mg twice daily with metformin 850 mg twice daily for 12 months, which reached a higher cumulative dosage than two other studies evaluating this comparison, showed flutamide to be more effective (MD -6.30, 95% CI -9.83 to -2.77) (very low quality evidence). Data showing reductions in Ferriman-Gallwey scores could not be pooled for four studies comparing finasteride with flutamide as the results were inconsistent (I² = 67%).Studies examining effects of hypocaloric diets reported reductions in BMI, but which did not result in reductions in Ferriman-Gallwey scores. Although certain cosmetic measures are commonly used, we did not identify any relevant RCTs.

AUTHORS' CONCLUSIONS

Treatments may need to incorporate pharmacological therapies, cosmetic procedures, and psychological support. For mild hirsutism there is evidence of limited quality that OCPs are effective. Flutamide 250 mg twice daily and spironolactone 100 mg daily appeared to be effective and safe, albeit the evidence was low to very low quality. Finasteride 5 mg daily showed inconsistent results in different comparisons, therefore no firm conclusions can be made. As the side effects of antiandrogens and finasteride are well known, these should be accounted for in any clinical decision-making. There was low quality evidence that metformin was ineffective for hirsutism and although GnRH analogues showed inconsistent results in reducing hirsutism they do have significant side effects.Further research should consist of well-designed, rigorously reported, head-to-head trials examining OCPs combined with antiandrogens or 5α-reductase inhibitor against OCP monotherapy, as well as the different antiandrogens and 5α-reductase inhibitors against each other. Outcomes should be based on standardised scales of participants' assessment of treatment efficacy, with a greater emphasis on change in quality of life as a result of treatment.

Hirsutism: an evidence-based treatment update

BACKGROUND

Hirsutism has a relatively high prevalence among women. Depending upon societal and ethnic norms, it can cause significant psychosocial distress. Importantly, hirsutism may be associated with underlying disorders and co-morbidities. Hirsutism should not simply be looked upon as an issue of cosmesis. Patients require appropriate evaluation so that underlying etiologies and associated sequelae are recognized and managed. Treatment of hirsutism often requires a multidisciplinary approach, and a variety of physical or pharmacologic modalities can be employed. Efficacy of these therapies is varied and depends, among other things, upon patient factors including the underlying etiology, hormonal drive, and local tissue sensitivity to androgens.

OBJECTIVE

The objective of this paper is to review and summarize current evidence evaluating the efficacy of various treatment modalities for hirsutism in premenopausal women.

METHODS

Online databases were searched to identify all relevant prior systematic reviews and meta-analyses as well as recently published (2012-present) randomized controlled trials (RCTs) on hirsutism treatment.

RESULTS

Four recently published RCTs met criteria for inclusion in our review. In addition, one meta-analysis and one systematic review/treatment guideline were identified in the recent literature. Physical modalities and oral contraceptive pills (OCPs) remain first-line treatments. Evidence supports the use of electrolysis for permanent hair removal in localized areas and lasers (particularly alexandrite and diode lasers) for permanent hair reduction. Topical eflornithine can be used as monotherapy for mild hirsutism and as an adjunct therapy with lasers or pharmacotherapy in more severe cases. Combined OCPs as a class are superior to placebo; however, antiandrogenic and low-dose neutral OCPs may be slightly more efficacious in improving hirsutism compared with other types of OCPs. Antiandrogens are indicated for moderate to severe hirsutism, with spironolactone being the first-line antiandrogen and finasteride and cyproterone acetate being second-line antiandrogens. Due to its risk for hepatotoxicity, flutamide is not considered a first-line therapy. If used, the lowest effective dose should be administered with careful monitoring of liver enzymes. Monotherapy with an insulin sensitizer does not significantly improve hirsutism. While insulin sensitizers improve important metabolic and endocrine aberrations in polycystic ovary syndrome, they are not recommended when hirsutism is the sole indication for use. Lifestyle modification counseling is recommended. Gonadotropin-releasing hormone analogs and glucocorticoids are only recommended in specific circumstances. Additional therapies without sufficient supportive evidence of efficacy are ovarian surgery, statins (HMG-CoA reductase inhibitors), and vitamin D supplementation.

LIMITATIONS

In general, most therapies garner recommendations that are weak (where the estimates of benefits versus risks of therapy are either closely balanced or uncertain) and are based on low- to moderate-quality evidence.

CONCLUSIONS

Risks and benefits of treatment must be carefully considered and discussed with the patient. Expectations for efficacy should be appropriately set. A minimum of 6 months is required to see benefit from pharmacotherapy and lifelong treatment is often necessary for sustained benefit.

Acne in patients with skin of color: practical management

Acne vulgaris is a prevalent and non-discriminatory condition affecting individuals of all races and ethnicities. As people with skin of color make up a rapidly expanding segment of the US population, dermatologic care must evolve accordingly to address their distinct concerns. Patients with skin of color with acne can be particularly challenging, given their potential for cosmetically disturbing complications, including post-inflammatory hyperpigmentation and keloid development. A variety of treatments have been shown to be effective in preventing or treating these complications. Topical retinoids are considered first-line therapy for acne in patients of color; topical alternatives include azelaic acid, dapsone, and antimicrobials. Hydroquinone may be used in combating post-inflammatory hyperpigmentation, specifically. For more severe acne, oral agents, including oral antibiotics or isotretinoin, may be used. Most recently, various lasers and phototherapies have been suggested for their safety and efficacy in patients with skin of color with acne. Ultimately, recognizing the clinical and histologic differences, as well as the variations in treatment regimens for darker skin types will allow for better care and patient satisfaction.

Pathogenesis and treatment of acne at women’s hyperandrogenism syndrome

Аспе is one of most spread people’s disease and is characterized by the piloseboceial complex affection. Acne pathogenesis is a multifactor one, and the hyperandrogenism favors the disease development. The article highlights the acne pathogenesis, discusses methods of the endocrinologic examination and treatment of women’s hyperandrogenism.

Acne vulgaris

Acne is a chronic inflammatory disease of the pilosebaceous unit resulting from androgen-induced increased sebum production, altered keratinisation, inflammation, and bacterial colonisation of hair follicles on the face, neck, chest, and back by Propionibacterium acnes. Although early colonisation with P acnes and family history might have important roles in the disease, exactly what triggers acne and how treatment affects the course of the disease remain unclear. Other factors such as diet have been implicated, but not proven. Facial scarring due to acne affects up to 20% of teenagers. Acne can persist into adulthood, with detrimental effects on self-esteem. There is no ideal treatment for acne, although a suitable regimen for reducing lesions can be found for most patients. Good quality evidence on comparative effectiveness of common topical and systemic acne therapies is scarce. Topical therapies including benzoyl peroxide, retinoids, and antibiotics when used in combination usually improve control of mild to moderate acne. Treatment with combined oral contraceptives can help women with acne. Patients with more severe inflammatory acne usually need oral antibiotics combined with topical benzoyl peroxide to decrease antibiotic-resistant organisms. Oral isotretinoin is the most effective therapy and is used early in severe disease, although its use is limited by teratogenicity and other side-effects. Availability, adverse effects, and cost, limit the use of photodynamic therapy. New research is needed into the therapeutic comparative effectiveness and safety of the many products available, and to better understand the natural history, subtypes, and triggers of acne.

Early hospital discharge of infants born to group B streptococci-positive mothers: a decision analysis

OBJECTIVE

To compare the cost-effectiveness of an additional 24-hour inpatient observation for asymptomatic term neonates born to group B streptococcus (GBS)-colonised mothers with adequate intrapartum antibiotic prophylaxis (IAP) after an initial 24-hour in-hospital observation.

DESIGN

Cost-effectiveness analysis from a societal perspective.

SETTING

United States.

POPULATION

Asymptomatic term neonates born to GBS-colonised mothers with IAP after an initial 24-hour in-hospital observation.

METHODS

Monte Carlo simulation for a decision tree model incorporating the following chance events: development of GBS sepsis during the second 24 hours of life, development of GBS sepsis between 48 hours and 7 days of life, prompt versus delayed treatment for sepsis, neonatal mortality and long-term health sequelae.

MAIN OUTCOME MEASURES

Expected cost and quality-adjusted life years (QALYs), Incremental cost-effectiveness ratio (ICER).

RESULTS

Delayed, versus early, hospital discharge results in similar mean expected QALYs, but substantially higher expected cost. The mean difference in QALY is 0.00016 (95% CI 0.00005-0.00040), whereas the mean difference in cost is $1170.96 (95% CI $750.13-1584.32). The ICER is estimated to be $9,771,520.87 per QALY (95% CI $2,573,139.89-24,407,017.82). The proportion of early-onset GBS that develops during the second 24 hours of life, the cost of 24 hours of inpatient observation, and the probability of long-term sequelae following prompt versus delayed treatment play important roles in determining the cost-effectiveness of delayed hospital discharge.

CONCLUSION

Cost-effectiveness analysis suggests that with adequate IAP, discharging asymptomatic term neonates to home after 24 hours is the preferred approach compared with 48 hours inpatient observation.
