Female Pattern Hair Loss and Androgen Excess: A Report From the Multidisciplinary Androgen Excess and PCOS Committee

Design, proof-of-concept of single robotic hair transplant mechanisms for both harvest and implant of hair grafts

The design and development of a prototype for a singular robotic hair transplant system capable of harvesting and implanting hair grafts were executed in this study. To establish a proof-of-concept for hair transplant procedures involving harvesting and implantation, a test system using a spherical phantom of the scalp was selected. The developed prototype of the robotic hair transplant system demonstrates the potential to reduce the duration that grafts remain without a blood supply, thereby minimizing hair graft damage. Additionally, the overall operation time for follicular unit extraction is comparatively shorter than that of conventional systems. Results from the robot vision tests indicate an 89.6% accuracy for hair graft detection with a 4 mm hair length phantom and 97.4% for a 2 mm hair length phantom. In the robot position control test, the root mean square error was found to be 1.268°, with a standard error of the mean of 0.203°. These outcomes suggest that the proposed system performs effectively under the conditions of a spherical phantom with a 2 mm hair length and a 5 mm distance between harvests.

Comparing the quality of life of adolescent girls with and without polycystic ovary syndrome and identifying the predictor factors

OBJECTIVES

Polycystic Ovary Syndrome (PCOS) is a complex hormonal disorder that affects the endocrine glands and reproductive processes in adolescent girls, potentially impacting their quality of life. This study aims to compare the quality of life between adolescent girls with PCOS and those without PCOS.

METHODS

The present study is an analytical cross-sectional study. It involved 12-18-year-old girls who were diagnosed with PCOS based on the Rotterdam criteria for the case group. An ordinal logistic regression model was employed to assess the impact of the studied variables on different levels of quality of life, and Odds Ratio (OR) values were determined for predictor variables.

RESULTS

The findings of the study revealed that the control group had a significantly higher percentage of individuals with excellent quality of life (score 209-260) compared to the group with polycystic ovary syndrome (p<0.05). The results of the ordinal logistic regression analysis indicated that age variables (OR=0.64, CI 95 %; 0.44-0.93), menstrual disorders (OR=0.07, CI 95 %; 0.01-0.38), and micromastia (OR=0.03, CI 95 %; 0.004-0.34) were identified as factors influencing the quality of life of girls with polycystic ovary syndrome.

CONCLUSIONS

It was concluded that patients with PCOS had a lower quality of life score. The variables of age, menstrual disorders, and micromastia were determined as influencing factors the quality of life. The results of this study are significant and warrant further research in this area, particularly with regard to the financial resources of patients in the challenging economic circumstances facing the nation - the majority of which are brought on by economic sanctions.

Association between PITX2 polymorphism and androgenetic alopecia in the Indian population

Background Androgenetic alopecia, also known as male pattern baldness, is a common form of hair loss influenced by environmental, hormonal, and genetic factors. According to recent research, the PITX2 gene may play a key role in the pathophysiology of androgenetic alopecia (AGA). Objective This study examines the association between genetic variants of the PITX2 gene and AGA risk. Methods The genomic DNA was extracted from peripheral blood samples collected from 70 male AGA patients and 60 non-androgenetic alopecia controls. The isolated DNA was quantified and the genotype for three PITX2 polymorphisms (rs2200733, rs10033464, and rs13143308) was identified using TaqMan assays. The statistical analysis was done to determine the allele frequency of genetic variants between AGA and non-AGA groups. Result The demographic profile of the study population showed that the AGA and non-AGA groups differed in age. The AGA group had higher blood pressure, a higher prevalence of smoking, alcohol consumption, metabolic syndrome, insulin resistance, and a higher incidence of family history. Through genetic analysis, significant correlations were found between AGA risk and specific PITX2 polymorphisms, significantly with the rs2200733 allele (OR = 6.08, p < 0.001*), the rs1003464 G allele (OR = 2.02, p < 0.019*) and the rs13143308 showed GT genotype (OR = 4.26, p < 0.001*). Conclusion Based on our findings, the PITX2 polymorphisms may play a vital role in the development of AGA. This study also found the interactions between genetic and environmental factors in AGA pathogenesis.

Prolactin: A Mammalian Stress Hormone and Its Role in Cutaneous Pathophysiology

The hormone prolactin (PRL) is best recognised for its indispensable role in mammalian biology, specifically the regulation of lactation. Bearing in mind that the mammary gland is a modified sweat gland, it is perhaps unsurprising to discover that PRL also plays a significant role in cutaneous biology and is implicated in the pathogenesis of a range of skin diseases, often those reportedly triggered and/or exacerbated by psychological stress. Given that PRL has been implicated in over 300 biological processes, spanning reproduction and hair growth and thermo- to immunoregulation, a comprehensive understanding of the relationship between PRL and the skin remains frustratingly elusive. In an historical curiosity, the first hint that PRL could affect skin biology came from the observation of seborrhoea in patients with post-encephalitic Parkinsonism as a result of another global pandemic, encephalitis lethargica, at the beginning of the last century. As PRL is now being postulated as a potential immunomodulator for COVID-19 infection, it is perhaps timeous to re-examine this pluripotent hormone with cytokine-like properties in the cutaneous context, drawing together our understanding of the role of PRL in skin disease to illustrate how targeting PRL-mediated signalling may represent a novel strategy to treat a range of skin diseases and hair disorders.

Polycystic ovary syndrome

Despite affecting ~11-13% of women globally, polycystic ovary syndrome (PCOS) is a substantially understudied condition. PCOS, possibly extending to men's health, imposes a considerable health and economic burden worldwide. Diagnosis in adults follows the International Evidence-based Guideline for the Assessment and Management of Polycystic Ovary Syndrome, requiring two out of three criteria - clinical or biochemical hyperandrogenism, ovulatory dysfunction, and/or specific ovarian morphological characteristics or elevated anti-Müllerian hormone. However, diagnosing adolescents omits ovarian morphology and anti-Müllerian hormone considerations. PCOS, marked by insulin resistance and hyperandrogenism, strongly contributes to early-onset type 2 diabetes, with increased odds for cardiovascular diseases. Reproduction-related implications include irregular menstrual cycles, anovulatory infertility, heightened risks of pregnancy complications and endometrial cancer. Beyond physiological manifestations, PCOS is associated with anxiety, depression, eating disorders, psychosexual dysfunction and negative body image, collectively contributing to diminished health-related quality of life in patients. Despite its high prevalence persisting into menopause, diagnosing PCOS often involves extended timelines and multiple health-care visits. Treatment remains ad hoc owing to limited understanding of underlying mechanisms, highlighting the need for research delineating the aetiology and pathophysiology of the syndrome. Identifying factors contributing to PCOS will pave the way for personalized medicine approaches. Additionally, exploring novel biomarkers, refining diagnostic criteria and advancing treatment modalities will be crucial in enhancing the precision and efficacy of interventions that will positively impact the lives of patients.

Medical Treatment for Androgenetic Alopecia

Androgenetic alopecia is a common type of hair loss, which is generally influenced by genetic factors and systemic androgens resulting in follicular miniaturization.1 It can cause cosmetic problems leading to psychological distress among affected men and women. Effective standard medical treatments available are topical minoxidil 2 to 5%, oral finasteride, oral dutasteride, and hair transplantation.1 However, some patients do not achieve favorable results with standard treatments. For these reasons, other novel treatments have been developed, including new medications, regenerative medicines (autologous platelet-rich plasma, adipose-derived stem cells, micrograft generation, and exosome), and low-level laser therapy.

Effects of ketogenic diet on weight loss parameters among obese or overweight patients with polycystic ovary syndrome: a systematic review and meta-analysis of randomized controlled trails

Aim

To evaluate how effective a low carbohydrate ketogenic diet (KD) is for changing key physical measurements such as weight, waist circumference (WC), body mass index (BMI), and fat mass (FM) in women with polycystic ovary syndrome (PCOS) who were obese or overweight.

Methods

Several online databases, including PubMed, Scopus, EMBASE, Cochrane Library, and Web of Science (WOS), were searched systematically to find relevant randomized controlled trials (RCTs) up until June 2023. The Q-test and I2 statistics were used to assess the level of heterogeneity among the included studies. The data were then combined using either a fixed or random effects model and presented as a weighted mean difference (WMD) along with a 95% confidence interval (CI).

Results

Of the 682 citations, 11 RCTs were included. The pooled results showed a significant decrease in the WMD of weight levels [WMD = -9.13 kg; 95% CI, -11.88, -6.39, P < 0.001; I2 = 87.23%] following KD. Moreover, KD significantly reduced BMI levels [WMD = -2.93 kg/m2; 95% CI, -3.65, -2.21, P < 0.001; I2 = 78.81%] compared to the controls. Patients with PCOS received KD demonstrated significant decrease in WC [WMD = -7.62 cm; 95% CI, -10.73, -4.50, P < 0.001; I2 = 89.17%] and FM [WMD = -5.32 kg; 95% CI, -7.29, -3.36, P < 0.001; I2 = 83.97%].

Conclusion

KD was associated with lower weight loss (WL) parameters, including weight, BMI, WC, and FM, in obese or overweight women with PCOS, highlighting the significance of physicians and nurses in taking care of the nutritional needs of overweight/obese patients with PCOS.

Potassium levels in women with polycystic ovary syndrome using spironolactone for long-term

OBJECTIVE

Spironolactone (SPL) has been used to manage hyperandrogenic manifestations in women with polycystic ovary syndrome (PCOS), but data on the risk of hyperkalemia in this population are scarce. The aim of this study was to evaluate the incidence of hyperkalemia in women with PCOS using SPL in the long term.

DESIGN

Single-centre retrospective study.

PATIENTS

Inclusion and analysis of 98 treatment periods in 78 women with PCOS (20 of whom were duplicates, returning after treatment interruption for a mean of 38 months) who received SPL for a minimum of 12 months and had at least three measurements of potassium levels over time.

MEASUREMENTS

Clinical and hormonal profiles before and during SPL treatment.

RESULTS

Mean age was 29.1 (SD: 9.6) years, and body mass index was 32.2 (SD: 8.1) kg/m². Nine patients had diabetes, and 22 had prediabetes. SPL was used in combination with combined oral contraceptive pills in 55 participants and progestin-only pills/long-acting reversible contraception in 28; metformin was added in 35, and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers in 15. Median SPL dose was 100 (range: 50-150) mg. A total of 327 serum potassium measurements were obtained (84 pre-exposure and 243 postexposure). Four potassium measurements were above the reference range before exposure and 19 during exposure. All potassium measurements above the reference range during follow-up were classified as mild hyperkalemia (5.1-5.5 mEq/L).

CONCLUSIONS

The present findings suggest that women with PCOS, without kidney or heart disease, using SPL combined with hormonal contraception for managing clinical hyperandrogenism have a low incidence of hyperkalemia and well-tolerated minor adverse effects.

The effect of an oral product containing Amla fruit (Phyllanthus emblica L.) on female androgenetic alopecia: A randomized controlled trial

ETHNOPHARMACOLOGICAL RELEVANCE

Amla (Phyllanthus emblica) fruit has been emphasized as a hair tonic in Traditional Persian Medicine (TPM) and recommended for hair loss orally and topically.

AIM OF THE STUDY

This study aimed to investigate the effect of an oral product containing Amla fruit on Female Androgenetic Alopecia (FAGA).

MATERIALS AND METHODS

This study was a triple-blind, randomized, controlled clinical trial. Sixty women with FAGA were randomly assigned into two groups of thirty. The intervention group received ten cc Amla syrup thrice a day for 12 weeks. The second group received a placebo with the same dose and duration. Hair growth parameters were analyzed using TrichoScan before and after 12 weeks of intervention. Physician and patient satisfaction were assessed using the CGI-I and PGI-I questionnaires, respectively.

RESULTS

Twenty-seven participants in the intervention group and 25 in the placebo group completed the trial. Based on our findings, the anagen-to-telogen ratio increased significantly in the intervention group compared with the group who received placebo (F = 10.4, P = 0.002). Physician and patient satisfaction increased in the amla group compared with placebo at 12th weeks of intervention (P<0.001), (P<0.001). The formula had no remarkable side effects. Only one case of mild constipation was reported in one of the participants after one month of consuming Amla syrup.

CONCLUSION

The results of this study demonstrated that Amla syrup could help treat androgenic hair loss in women and increase the anagen phase. Further studies are needed to evaluate this potential treatment for FAGA.

The Menopausal Transition: Is the Hair Follicle "Going through Menopause"?

This article explores the link between menopause and changes in the hair follicle (HF) lifecycle, focusing on hormonal and metabolic dynamics. During menopause, hormonal fluctuations and aging can impact the HF, leading to phenomena such as thinning, loss of volume, and changes in hair texture. These changes are primarily attributed to a decrease in estrogen levels. However, not all women experience significant hair changes during menopause, and the extent of transformations can vary considerably from person to person, influenced by genetic factors, stress, diet, and other elements. Furthermore, menopause mirrors the aging process, affecting metabolism and blood flow to the HFs, influencing the availability of vital nutrients. The article also discusses the key role of energy metabolism in the HF lifecycle and the effect of hormones, particularly estrogens, on metabolic efficiency. The concept of a possible "menopause" clinically independent of menopause is introduced, related to changes in HF metabolism, emphasizing the importance of individual factors such as estrogen receptor responses, genetics, and last but not least, the microbiota in determining these dynamics.

Assessment of Occipital Involvement Among a Large Population of Females with Pattern Hair Loss in Saudi Arabia

Background

Cumulative evidence suggests the involvement of the occipital region in female pattern hair loss (FPHL). However, most of the studies that have been published so far concerned relatively small samples of patients.

Purpose

To assess the occipital involvement in FPHL and analyze its correlation with disease severity among a large sample of patients.

Patients and Methods

A retrospective study involved 1000 adult women with FPHL, between January 2020 and August 2022. Occipital involvement was defined as more than 10% of thin hairs (<0.03 mm). Baseline trichometry parameters in the frontal and occipital regions were analyzed.

Results

Occipital involvement was observed in 32.4% of the patients. Positive correlations between frontal and occipital regions were observed for all trichometry parameters; the strongest concerned average hair shaft thickness (Pearson's coefficient r=0.708), cumulative hair thickness (r=0.673), and trichometry-derived Sinclair scale (r=0.656). The risk of occipital involvement increased independently with the disease severity in frontal region; however, the disease progression was slower in the occipital compared to frontal region.

Conclusion

One-third of females in our study with FPHL had occipital involvement. This has a major impact on the methods used to diagnose pattern hair loss in females and their treatment plan including hair restoration surgery.

Semaglutide Treatment of Excessive Body Weight in Obese PCOS Patients Unresponsive to Lifestyle Programs

In spite of the widespread use of lifestyle modifications programs, many patients with PCOS are obese and prevalence of obesity in PCOS remains high. In this study, we present the data on the use of semaglutide, an incretin mimetic drug, in obese PCOS patients who were unresponsive to a lifestyle modification program. Twenty-seven obese patients with a diagnosis of PCOS, who did not reduce their body weight by a lifestyle modification program, were included in this study and treated by semaglutide, 0.5 mg subcutaneously once a week. After three months of treatment, an improvement in body weight with a mean decrease in body weight of 7.6 kg and a mean BMI loss of 3.1 was observed, while very few side effects were reported. Almost 80% of the studied obese PCOS patients obtained at least a 5% decrease in their body weight. Only a few patients (22%) obtained a decrease in body weight lower than 5% and were considered non-responsive to semaglutide, at least at the used doses. These patients presented a more severe obesity than responsive patients. Independently of results on body weight, and in patients who did not obtain a 5% decrease in their body weight, insulin basal values decreased, and HOMA-IR improved. Fasting blood glucose normalized in 80% of semaglutide-treated IFG PCOS women. In patients who were responsive to semaglutide (weight loss > 5%), the treatment was continued for additional three months. Weight loss slowed but continued and, at the end of the six months of therapy, the mean body weight loss was 11.5 kg and mean BMI reduced from 34.4 to 29.4. A total of 80% of responsive patients normalized menstrual cycles. In conclusion, treatment with semaglutide, at low doses, significantly reduces body weight in almost 80% of obese PCOS patients who were unresponsive to a previous lifestyle plan. It is often associated with the normalization of menstrual cycles, and these important results are obtained with very few side effects.

Efficacy of Dr. SKS Hair Booster Serum in the Treatment of Female Pattern Alopecia in Patients With PCOS: An Open-Label, Non-randomized, Prospective Study

Background Many patients with polycystic ovary syndrome (PCOS) exhibit female pattern hair loss (FPHL). A more advanced, efficient, and suitable therapeutic approach is required to effectively manage FPHL in patients with PCOS. Aim Dr. SKS Hair Booster Serum is composed of copper, niacinamide, hyaluronic acid, thiamine, riboflavin, and biotin; each of these constituents has demonstrated individual efficacy in promoting hair growth and enhancing hair quality. We hereby assess the effectiveness of this novel hair formulation in treating FPHL in PCOS. Methods This was an open-label, non-randomized, multicenter, prospective, large study with a wide range of age groups. The study involving 1,000 females aged 25-50 years, diagnosed with PCOS and having complaints of FPHL with Ludwig grades I and II. Each patient received a monthly session of Dr. SKS Hair Booster Serum, with 1 mL of serum administered through injection into the superficial layer (dermis) of the scalp using a tiny infusion via an insulin syringe, mesotherapy, or via a derma roller/derma pen. All the patients were subjected to standard global photography, video microscopic assessment (vellus hair counts, terminal hair counts, and hair shaft diameter), and a subject self-assessment questionnaire at baseline and six months after the treatment. Results After six months of the treatment, the hair shaft diameter, terminal hair counts, and hair growth rate were significantly increased than baseline (p≤0.0001), and a significant reduction was noted in vellus hair counts than baseline measurement (p<0.00001). These findings are suggestive of improved hair regrowth after the treatment. No adverse events were recorded during the study. Statistically significant improvements were observed in hair parameters (overall hair fall rate, hair texture, hair volume, and scalp itching) after six months of treatment than baseline. Conclusion Dr. SKS Hair Booster Serum has been shown to be an effective treatment for FPHL in patients with PCOS. This study marks the first investigation into the use of Dr. SKS Hair Booster Serum in patients with PCOS.

Differences in Demographic and Clinical Characteristics Among Subtypes of Female Pattern Hair Loss

Background

Female pattern hair loss (FPHL) is the most common hair loss disorder in women that can be classified into three patterns, including Ludwig, Olsen, and Hamilton-Norwood subtypes. Information regarding the comparison of demographics, clinical characteristics, and associated comorbidities among subtypes of FPHL is scarce and contradictory.

Objective

To evaluate and compare the epidemiology, clinical manifestations, and comorbid conditions of FPHL subtypes and determine their associated factors.

Methods

This retrospective study included patients who were diagnosed with FPHL between January 2000 and November 2021. Participants were classified into three subtypes, namely Ludwig, Olsen, and Hamilton-Norwood, and were statistically compared. Variables significantly associated with each FPHL subtype were identified using multivariable multinomial logistic regression analysis.

Results

Among the 519 patients with FPHL, the Ludwig subtype was the most prevalent (51.1%), followed by the Olsen (32.9%) and Hamilton-Norwood (16%) subtypes. The Hamilton-Norwood subtype revealed significantly higher frequencies of early disease onset (61.4%), menstrual irregularity (22.9%), polycystic ovary syndrome (PCOS, 18.1%), and seborrhea (30.1%) but lower frequencies of overweight (24.1%) and type 2 diabetes mellitus (DM, 2.4%). Multivariable multinomial regression analysis demonstrated that the Hamilton-Norwood subtype was a predictor for early disease onset and PCOS compared to Ludwig (early onset: odds ratio (OR) = 2.14, 95% confidence interval (CI) = 1.39-4.22, P = 0.02; PCOS: OR = 2.02, 95% CI = 1.55-4.84, P = 0.03), and Olsen (early onset: OR = 1.89, 95% CI = 1.03-3.92, P = 0.04; PCOS: OR = 2.24, 95% CI = 1.89-5.31, P = 0.01). In contrast, the Hamilton-Norwood pattern was at decreased risk for type 2 DM compared to Ludwig (OR = 0.51, 95% CI = 0.03-0.82, P = 0.02), and Olsen (OR = 0.68, 95% CI = 0.04-0.79, P = 0.03).

Conclusion

The Ludwig pattern was found to be the most prevalent FPHL subtype among Thai patients. Moreover, the Hamilton-Norwood subtype was associated with early disease onset and PCOS, whereas the Ludwig and Olsen subtypes were associated with type 2 DM.

Female Pattern Hair Loss and Negative Psychological Impact: Possible Role of Brain-derived Neurotrophic Factor (BDNF)

INTRODUCTION

Female Pattern Hair Loss (FPHL) is considered the most common type of hair loss in females. Women with FPHL may suffer from psychological distress and defective social functioning. Patients with psychiatric and neurodegenerative disorders almost have a deficient brain and blood brain-derived neurotrophic factor levels (BDNF). This serum BDNF level may act as a diagnostic marker for negative psychological impact in FPHL patients.

OBJECTIVES

Evaluate the levels of serum BDNF in patients with FPHL and correlate its level to the severity of alopecia and the degree of psychological impact.

METHODS

Forty-six female patients with FPHL and 41 healthy age-matched female volunteers as a control were included in the study. Patients filled out a Dermatology Life Quality Index questionnaire. Both patients and controls filled Beck Depression Inventory, Beck Anxiety Inventory, and Perceived Stress Scale (PSS) questionnaires. Serum levels of BDNF were measured for all the participants using the ELISA technique.

RESULTS

Patients with FPHL had significantly lower levels of BDNF and significantly higher Beck depression inventory score and PSS questionnaire scores. There is a significant negative correlation between serum levels of BDNF and Beck Depression Inventory, Beck Anxiety Inventory, and PSS questionnaire scores.

CONCLUSIONS

Patients with FPHL are at a high risk to develop chronic stress and depression. The serum level of BDNF is a good predictor for the assessment of chronic stress and depression in FPHL patients.

Current Guidelines for Diagnosing PCOS

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder of reproductive-aged women. Much of the confusion surrounding PCOS diagnosis stems from the broad heterogeneity of symptomology experienced by women with PCOS. The diverse features of the syndrome have led to a number of diagnostic criteria over the years. This manuscript describes each of the current composite criteria and individually breaks down each component. The importance of accurate diagnosis for both clinical care and research is emphasized.

PCOS in Adolescents-Ongoing Riddles in Diagnosis and Treatment

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of reproductive age. A diagnosis of PCOS is established when a patient exhibits two of three Rotterdam criteria: oligoovulation or anovulation, excess androgen activity, and polycystic ovarian morphology. The pathogenesis of PCOS, as it affects adolescents, is often discussed in terms of a "two-hit" theory. This refers to a stepwise process in which the first "hit" is an inborn congenitally programmed predisposition, while the second "hit" arises from a provocative factor such as insulin resistance. The dynamic physiological and anatomical changes which occur in puberty make for a challenging diagnosis in this group of patients. It is important to be mindful of the physiological particularities in adolescence which often mimic the symptoms of PCOS. In their first-year post-menarche, approximately 75% of menstruating adolescents report their cycle to last between 21-45 days. Recent studies have shown that regular menstrual cyclicity is only achieved within 2-3 years post-menarche. Anovulation, as a crucial diagnostic element for PCOS, features in about half of early-post-menarchal adolescents. Hirsutism and acne are the most common clinical manifestations of hyperandrogenism, and mild features are developed by most adolescents as a result of elevated androgen levels. Distinguishing between a pathological sign and normal features of maturation is often difficult. A polycystic ovarian morphology (PCOM) through ultrasound has been found in up to 40%, 35%, and 33.3% of patients when assessed at 2, 3, and 4 years, respectively, after menarche. PCOM in adolescence is not associated with future abnormalities in ovulatory rate or menstrual cycle duration. For this reason, international guidelines recommend against the use of pelvic ultrasound until 8 years post-menarche. The primary aim of management is focused mainly on improving hormonal and metabolic status, the prevention of future comorbid complications, and generally improving the overall quality of life in young women with PCOS. Considerable controversy surrounds the choice of optimal pharmacological treatment to address PCOS in adolescents. Reliable studies, which include this sub-section of the population, are very limited. There is a lack of robust and reliable trials in the literature addressing the use of combined oral contraceptives. Further work needs to be undertaken in order to provide safe and effective care to the adolescent population in this regard.

Polycystic ovary syndrome and iron overload: biochemical link and underlying mechanisms with potential novel therapeutic avenues

Polycystic ovary syndrome (PCOS) is an endocrine and metabolic disorder in women with components of significant genetic predisposition and possibly multiple, but not yet clearly defined, triggers. This disorder shares several clinical features with hemochromatosis, a genetically defined inheritable disorder of iron overload, which includes insulin resistance, increased adiposity, diabetes, fatty liver, infertility, and hyperandrogenism. A notable difference between the two disorders, however, is that the clinical symptoms in PCOS appear at much younger age whereas they become evident in hemochromatosis at a much later age. Nonetheless, noticeable accumulation of excess iron in the body is a common finding in both disorders even at adolescence. Hepcidin, the iron-regulatory hormone secreted by the liver, is reduced in both disorders and consequently increases intestinal iron absorption. Recent studies have shown that gut bacteria play a critical role in the control of iron absorption in the intestine. As dysbiosis is a common finding between PCOS and hemochromatosis, changes in bacterial composition in the gut may represent another cause for iron overload in both diseases via increased iron absorption. This raises the possibility that strategies to prevent accumulation of excess iron with iron chelators and/or probiotics may have therapeutic potential in the management of polycystic ovary syndrome.

Female pattern hair loss and polycystic ovarian syndrome: more than just hirsutism

PURPOSE OF REVIEW

To explore the recent updates in the diagnosis, management, and clinical implications of androgenic alopecia among patients diagnosed with polycystic ovarian syndrome (PCOS).

RECENT FINDINGS

PCOS diagnosis continues to be the most common cause of infertility among reproductively aged women, serving as the most common endocrinopathy among this population. Female pattern hair loss (FPHL) has been seen to be associated and more common among patients with PCOS, however, there are limited studies examining the impact of FPHL among PCOS patients. Although hyperandrogenism is associated with FPHL, the pathophysiology continues to be unclear as FPHL can be present with normal biochemical androgen markers. Treatment can be complex, as common treatments to promote hair growth can exacerbate undesired hirsutism, which can be overcome by cosmetic treatments. New second-line treatment options such as low level laser therapy and platelet rich plasma have been emerging, with limited data supporting efficacy.

SUMMARY

PCOS is a complex endocrinological disorder that has significant gynecologic, cutaneous, and metabolic implications that require multidisciplinary collaboration and care. Reproductive goals should be thoroughly discussed prior to starting any treatment, as PCOS is the most common cause of infertility among reproductively-aged women.

Effects of Hormones and Endocrine Disorders on Hair Growth

Hormones have a close association with hair growth; thus, they have a big impact on the hair cycle and hair follicle structure. Many hormones control hair growth, cycle, and density. Hair abnormalities are frequent in therapeutic practice, and they can cause severe emotional discomfort depending on societal and ethnic standards. As a result, disorders that impact the endocrine system can induce a variety of physiological hair growth and cycling alterations. Hirsutism and patterned hair loss have a significant impact on human personality. These illnesses necessitate a comprehensive approach to diagnosis and treatment. The hormonal impact on hair growth and the association of different endocrine disorders with hair changes are briefly discussed here.

Increased Prevalence of Elevated DHEAS in PCOS Women with Non-Classic (B or C) Phenotypes: A Retrospective Analysis in Patients Aged 20 to 29 Years

It is well known that a subgroup of women with PCOS present an excessive adrenal androgen production, generally associated with ovarian hyperandrogenism. In the past, it has been impossible to correlate adrenal hyperandrogenism to any clinical or hormonal pattern of PCOS. However, adrenal androgens are strictly dependent on age and their blood values reduce by 40% in patients moving from their twenties to thirties. Due to this, serum DHEAS values are strongly influenced by the age distribution of studied populations. To avoid this bias, in this study we retrospectively analyzed the clinical and hormonal data of PCOS women in their twenties (age between 20 and 29 years). Data of 648 young hyperandrogenic women with PCOS were evaluated. Serum DHEAS was increased in a third (33%) of studied patients and was associated with higher values of testosterone (T) and androstenedione (A). In each phenotype, patients with high DHEAS had higher values of T and A than patients with normal DHEAS of the same phenotype. Therefore, a DHEAS increase is generally part of a generalized higher androgen production in a subgroup of PCOS patients, independently of the finding of anovulatory or ovulatory cycles or of polycystic or normal ovaries. However, our study showed some important differences between PCOS phenotypes. A lower prevalence of increased DHEAS in A phenotype PCOS patients who generally have the highest androgen levels, versus non-classic (B or C) PCOS phenotypes, was observed. It was also found that patients with A phenotype PCOS present significantly lower BMI and serum insulin than patients with normal DHEAS of the same phenotype while, in patients with the B or C phenotype, the opposite occurs. We conclude that adrenal hyperandrogenism is more common in patients with non-classic (B and C) phenotypes of PCOS and is generally part of a generalized higher production of androgens in a subgroup of PCOS patients. However, other factors may increase the adrenal androgen production and influence the clinical expression of the syndrome. More studies in large, selected for age, populations of PCOS women with different phenotypes are needed.

Early diagnosis in polycystic ovary syndrome

ABSTRACT

NPs are in an ideal position to educate patients on the lifelong implications of polycystic ovary syndrome (PCOS). A timely diagnosis and comprehensive plan are needed to appropriately manage patients with PCOS. This article highlights diagnostic criteria, common comorbid conditions, psychological impacts of the clinical manifestations, management approaches, and implications for NPs.

Comparing Lean and Obese PCOS in Different PCOS Phenotypes: Evidence That the Body Weight Is More Important than the Rotterdam Phenotype in Influencing the Metabolic Status

Polycystic Ovary Syndrome (PCOS) represents a heterogeneous disorder and, using Rotterdam diagnostic criteria, four main phenotypes (A, B, C, and D) have been distinguished. However, it remains unclear whether lean versus obesity status influences findings in the various phenotypes of women with PCOS. 274 women with PCOS were consecutively assessed. Among these women, there were 149 with phenotype A, 24 with phenotype B, 94 with phenotype C, and 7 with phenotype D. We found normal body weight to be very common (65%) in phenotype C patients, common (43%) in phenotype A and D patients, and less represented (but still 25%) in phenotype B patients. Obesity was common in phenotype B (54%) and phenotype A (33%) patients and uncommon in phenotype C (only 11%) and phenotype D (14%) patients. Obese and lean patients of each phenotype were compared. Compared to the phenotype C PCOS patients, both phenotype A and B patients had higher total testosterone circulating values and higher luteinizing hormone/follicle stimulating hormone (LH/FSH) ratio (p < 0.01) while anti-Mullerian hormone (AMH) levels were higher only in phenotype A PCOS patients. Instead, in the three obese PCOS phenotypes no differences in serum insulin, Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) calculation, and lipid blood values were observed. Analysis of data of lean patients gave similar results. Compared to the phenotype C PCOS patients, both phenotype A and B patients had higher total testosterone circulating values and higher LH/FSH ratio (p < 0.01) while AMH levels were higher only in phenotype A PCOS patients. However, no differences were observed in the circulating insulin levels, HOMA-IR calculation, or blood lipids between the three groups of lean PCOS patients. We conclude that Rotterdam phenotypes express the differences between PCOS patients in terms of ovulatory pattern and androgen secretion but fail to differentiate between obese patients with altered metabolic patterns and lean patients with normal metabolic patterns. A new classification of PCOS patients is needed and it should consider the influence of body weight on the metabolic patterns of PCOS patients.

Criteria for Diagnosis of Polycystic Ovary Syndrome during Adolescence: Literature Review

Polycystic ovary syndrome (PCOS) is one of the most common endocrine conditions in women. PCOS may be more challenging to diagnose during adolescence due to an overlap with the physiological events of puberty, which are part of the diagnostic criteria in adult women. This review focuses on the evidence available in relation to PCOS diagnostic criteria for adolescents. Adolescent PCOS should be diagnosed using two main criteria irregular -menstrual cycles (relative to number of years post-menarche) and hyperandrogenism (clinical and/or biochemical); after excluding other conditions that mimic PCOS. Accurate definitions of the two main criteria will decrease challenges/controversies with the diagnosis and provide timely diagnosis during adolescence to establish early management. Despite the attempts to create accurate diagnostic criteria and definitions, this review highlights the limited research in this area, especially in the follow up of adolescents presenting with one diagnostic feature that are called “at risk of PCOS”. Studies in adolescents continue to use the Rotterdam diagnostic criteria that uses pelvic ultrasound. This is inappropriate, because previous and emerging data that show many healthy adolescents have polycystic ovarian morphology in the early years post-menarche. In the future, anti-Müllerian hormone levels might help support PCOS diagnosis if adolescents meet two main criteria.

Epidemiology and disease burden of androgenetic alopecia in college freshmen in China: A population-based study

Objective

To evaluate the epidemiology and disease burden of androgenetic alopecia (AGA) in college freshmen in China.

Methods

This population-based cross-sectional survey was carried out among 9227 freshmen of two comprehensive universities in two cities of China (Changsha and Xiamen) from September 2018 to October 2018. Questionnaires covering basic issues, surrounding demographic information, history of diseases, living habits, comorbidities, etc. were completed online in a self-reported manner Dermatological examination was performed by certified dermatologists. The disease burden of AGA, which includes health-related quality of life, symptoms of anxiety, symptoms of depression and quality of sleep, was measured by EQ-5D-3L, PHQ-2, GAD-2 and PSQI, respectively.

Results

The prevalence of AGA in college freshmen in China was 5.3/1000. Male was significantly associated with higher prevalence of AGA (7.9/1000, P<0.01) while female with lower risk of AGA (OR = 0.29, P = 0.002). There was no significant association between BMI and AGA, nor predilection of AGA in the Han nationality or the other ethnic minorities. Annual household income or parental highest educational level exerted no significant influence on the prevalence of AGA. Rosacea (OR = 3.22, P = 0.019) was significantly associated with higher prevalence of AGA while acne seemed not to be related to AGA. The scores of EQ-5D, GAD-2, PHQ-2 and PSQI were not significantly different between students with and without AGA.

Conclusion

The onset of AGA in Chinese college freshmen differ between genders and was significantly associated with rosacea.

Evaluation of the safety and effectiveness of intradermal administration of QR678 Neo® hair growth factor formulation: A phase-IV, open-label, single-arm multi-ethnicity clinical trial

BACKGROUND

Intradermal administration of QR678 Neo^® hair re-growth factor formulation has already proven its effectiveness and safety in treating androgenetic alopecia and female pattern hair loss.

AIM

This study aims to evaluate effectiveness and safety of hair re-growth factor formulation at multiple centers for reduction of hair fall and regrowth of hair in androgenetic alopecia and female pattern hair loss.

MATERIALS AND METHODS

An open-label, prospective, and interventional study was carried out at multiple centers of different countries. A total of 2428 patients with androgenetic alopecia and female pattern hair loss within the age range of 18-65 years were included in the study. Hair pull test, global photographic assessment, videomicroscopic assessment tests were performed at the beginning, after fourth and eighth sessions, and self-assessment through questionnaire related to satisfaction and side effects was carried out at beginning and at after eight session.

RESULTS

Hair pull test was positive in only 12% of the patients after eight sessions. Beneficial results were noted in the global assessment score (mean-6) after fourth session and eighth session (mean-8). Huge improvement was noted in terminal hair count, vellus hair count, and hair density after eighth sessions. Also, with self-assessment score, a higher satisfaction score was noted. On long-term follow-up as well, no side effects were noted.

CONCLUSION

Intradermal administration of QR678 Neo^® is an innovative, efficacious, and safe technique for the treatment of androgenetic alopecia and female pattern hair loss.

Treatment with oral vitamin D alone, topical minoxidil, or combination of both in patients with female pattern hair loss: A comparative clinical and dermoscopic study

BACKGROUND

One of the most common dermatological complaints among female is female pattern hair loss (FPHL). Serum vitamin D is a factor lately taken into consideration in approaching patients complaining of hair loss.

AIM

To evaluate the serum level of 25-hydroxy vitamin D in patients with FPHL and to evaluate the efficacy of vitamin D therapy alone or combined with minoxidil in the treatment of this disease.

METHODS

45 patients with FPHL and 15 controls to measure serum level of vitamin D were enrolled in the study. Patients then were subdivided into 3 groups: group I received topical minoxidil and oral vitamin D, group II received topical minoxidil, and group III received oral vitamin D for 6 months. Clinical and dermoscopic evaluation was done for the three groups before and after treatment.

RESULTS

Vitamin D level was significantly decreased in patients compared to controls. After treatment, as regard Ludwig scale, there was statistically significant improvement in group I than II while no significant improvement was found in group III. Dermoscopy revealed that thin hair and single-hair unit were significantly improved in groups I and II, while it was not significantly improved in group III.

CONCLUSION

Oral vitamin D combination to topical minoxidil is recommended to treat patients with FPHL; they had better results than vitamin D or topical minoxidil alone.

Pharmacological Management of Pattern Hair Loss

Pattern hair loss (PHL) is a condition that worsens with time and the only way it can be slowed down is with pharmacological intervention. Pharmacological treatments for PHL, from an evidenced-based perspective with respect to safety and efficacy, are limited to only two drugs, minoxidil and finasteride. However, there are a host of drugs being used, off-label with limited evidence. This article attempts to review the literature on this topic, and the authors add to this, with their experience of over two decades on incorporating pharmacologic treatments along with hair transplantation in their management of PHL.

Cutaneous Manifestations and Hormonal Changes Among Polycystic Ovary Syndrome Patients at a Tertiary Care Center

Background: Polycystic ovary syndrome (PCOS) is a highly prevalent endocrine disorder affecting 5%-10% of women worldwide. PCOS patients usually present with cutaneous manifestations of hyperandrogenism, such as acne, hirsutism, and androgenic alopecia.

Objective: To estimate the prevalence of dermatological manifestations and their association with hormonal changes in PCOS patients. In addition, this study aimed to estimate the prevalence of comorbidities associated with PCOS and to demonstrate the referral pattern among Dermatology, Gynecology, and Primary Health Care (PHC).

Methods: This is a cross-sectional study conducted at King Abdulaziz Medical City (KAMC) in Jeddah, Saudi Arabia. All PCOS patients who attended KAMC from 2016 to 2021 were included. Data were collected through a retrospective chart review of the electronic medical record system (BestCare) and by utilizing a structured data collection sheet.

Results: A total of 447 female patients were diagnosed with PCOS with a median age of 29 years and a median BMI of 28.76 kg/m².The prevalence of cutaneous manifestations among patients was 68%. Hirsutism (47.3%), acne vulgaris (40.6%), and androgenic alopecia (20.3%) were the most common manifestations. The most common hormonal abnormalities were raised luteinizing hormone (LH) levels in 220 (49.1%) patients and raised LH/follicle-stimulating hormone (FSH) ratio in 159 (35.5%) patients. FSH, LH/FSH ratio, and age were significant predictors for acne vulgaris (P-value=0.01, 0.04, and 0.01, respectively). Obesity (44.20%), infertility (25.70%), and dyslipidemia (17%) were the most common comorbidities in our sample. Most patients' first visits and follow-ups were in PHC. 

Conclusion: The prevalence of cutaneous manifestations among PCOS patients is relatively high and plays a significant role in making the diagnosis. Therefore, physicians across multiple specialties need to be more aware of the full spectrum of PCOS presentations to alleviate it from its under-diagnosed status.

The effect of low glycemic index diet on the reproductive and clinical profile in women with polycystic ovarian syndrome: A systematic review and meta-analysis

Background

Treatment for polycystic ovary syndrome (PCOS) usually initiates with a series of lifestyle modifications such as diet, weight loss, and exercise.

Aims

We, therefore, conducted this meta-analysis to systematically review and evaluate the possible benefits of LGD on a range of anthropometric, clinical, and biochemical parameters in women with PCOS.

Methods

We performed a systematic search through major indexing databases, including Scopus, Pubmed/Medline, ISI web of science, Embase, Cochrane central, and CINAHL (1966-April 30, 2021) using key concepts of PCOS.

Results

Of 935 initial publications, 542 remain after duplicates removal. Then, 141 records were removed at the title and abstract screening level. After excluding 392 literatures, we finally included 8 articles. The final selected studies included 412 overweight and obese individuals with PCOS (207 cases in LGID group and 205 patients in comparators) with a mean age of 21-32 years. Measured emotional health (3 studies, 132 participants, SMD: -1.97; 95%CI:-3.54, -0.40, P = 0.01, I ² = 89%) and body hair (3 studies, 132 participants, SMD: -0.40; 95%CI:-0.46, -0.35, P < 0.0001, I ² = 0%), were found to be significantly lower in women in LGD vs control diet groups. Moreover, infertility (3 studies, 132 participants, SMD: 1.45; 95%CI: 0.30, 2.61, P = 0.01, I ² = 79%) was significantly higher in women in LGD vs control diet groups.

Conclusion

The present meta-analysis has shown that LGD may play a significant role in reducing the risk and improving the clinical and biochemical features of PCOS. So far the evidences for choosing the best dietary modalities for PCOS are not strong to make a definite recommendation.

Practical Approach to Hyperandrogenism in Women

The approach to hyperandrogenism in women varies depending on the woman's age and severity of symptoms. Once tumorous hyperandrogenism is excluded, the most common cause is PCOS. Hirsutism is the most common presenting symptom. The woman's concern about her symptoms plays an important role in the management of disease. Although measurement of testosterone is useful in identifying an underlying cause, care must be taken when interpreting the less accurate assays that are available commercially. Surgical resection is curative in tumorous etiologies, whereas medical management is the mainstay for non-tumorous causes.

Female Pattern Hair Loss: Why the Follicular Unit Transplantation Surgical Technique Remains a Good Option

BACKGROUND

Female pattern hair loss is a common nonscarring alopecia that can present with several patterns of decreased hair density. The condition is very bothersome to affected women, and although there are multiple nonsurgical options, surgical follicular unit transplantation remains one of the most effective options.

METHODS

A retrospective chart review was performed of the senior author's (C.O.U.) experience and technique of follicular unit transplantation for treatment of female pattern hair loss.

RESULTS

A total of 751 patients with female pattern hair loss underwent follicular unit transplantation over the past 31 years. Average patient age was 48 years. Patients with small areas of hair loss made up 40 percent of the group (Ludwig stage I), those with medium-sized areas constituted 45 percent (Ludwig stage II), and those with large areas constituted 15 percent (Ludwig stage III). The average operative time was 3 hours 21 minutes. One hundred thirty-five patients (18 percent) underwent a second replacement, at an average period of 4 years after the procedure, because of the progressive nature of female pattern hair loss. Complications included donor-site scar widening in six patients and folliculitis in 17 patients.

CONCLUSION

Follicular unit transplantation is an excellent option for treatment of female pattern hair loss patients, as there is no need to shave the recipient sites, operative times are shorter than for follicular unit excision techniques, and the incidence of complications is very low.

CLINICAL QUESTION/LEVEL OF EVIDENCE

Therapeutic, IV.

Update on polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a common disorder in reproductive-age women. In 2018, an international evidence-based guideline announced recommendations spanning a wide range of issues on the assessment and management of PCOS. From the 166 recommendations, the present study reviews those that are of particular clinical relevance for daily practice and introduces other relevant studies that have been published since the global guideline. The 2018 guideline increased the antral follicle count cutoff for the diagnosis of PCOS from 12 to 20 when using a high-frequency probe. Hirsutism was defined as having a score of ≥4–6 based on a lower percentile of 85%–90% or cluster analysis, which was lower than the traditionally used 95th percentile-based cutoff. The diagnosis of PCOS in adolescents is challenging, and irregular menstruation was defined carefully according to years from menarche. The use of ultrasonography for the diagnosis of PCOS was restricted to those 8 years after menarche. As medication for non-fertility indications, combined oral contraceptives are the first-line drug. Metformin, in addition to lifestyle modifications, should be considered for adult patients with a body mass index ≥25 kg/m² for the management of weight and metabolic outcomes. An aromatase inhibitor is the recommended first-line medication for ovulation induction, a subsequent individual patient data meta-analysis also reported the same conclusion. Whether the new global guideline will be fully adopted by many specialists and change clinical practice is open to question. Further studies are needed to better understand and manage PCOS patients well.

Use of facial care products and frontal fibrosing alopecia: Coincidence or true association?

The increasing incidence of frontal fibrosing alopecia (FFA) suggests that environmental factors may be related to the pathogenesis. Recent studies reported potential association between the use of facial care products and FFA. The aim of this study was to investigate the possible association between the use of facial care products and FFA in Asian females. A total of 250 females (50 FFA patients, 100 pattern hair loss [PHL] patients, and 100 normal controls) were recruited and completed a questionnaire to obtain information approximately facial care products and various environmental factors. Our study revealed the use of moisturizer to be significantly higher in the FFA group compared to normal controls (p < 0.001), and sunscreen use was significantly higher in the PHL group than in the control group (adjusted p < 0.001). Subjects with FFA or PHL reported significantly higher use of both sunscreen and moisturizer compared to normal controls (p < 0.001). This study focused on Asian populations. Our results revealed a high frequency of moisturizer and sunscreen use in both FFA and PHL among Asian females. Therefore, the use of facial care products appears not to be linked to the true disease mechanism of FFA, but rather to appearance-related concerns of patients.

Comparison of PCOS phenotypes in adolescent and young adult Mediterranean women with possible PCOS

PURPOSE

During adolescence, PCOS features are supposed to be in evolution. Because of this, the diagnosis of PCOS in adolescence is often unclear and few studies have compared adolescent and adult PCOS phenotype distribution and features. The aim is to compare phenotypes in adolescents and young adults with PCOS.

METHODS

109 girls aged from 13 to 19 years were retrospectively studied. All patients had a gynecological age > 2 years. 63 patients were adolescents (3-5 years beyond menarche) while 46 patients were young adults (6-9 years beyond menarche). Diagnosis of different PCOS phenotypes (A, B, C, D) was made according to the Rotterdam criteria. Clinical data (menstrual cycles, BMI, presence of hirsutism), androgen circulating levels (total testosterone, androstenedione, dehydroepiandrosterone sulphate) and ovarian morphology by ultrasound were assessed.

RESULTS

109 patients presented PCOS according to the Rotterdam criteria. Phenotype A was by far the most common phenotype (73.4%) followed by phenotype B (21.1%). Only few patients had phenotype C (4.6%) or phenotype D (0.9%). When patients were divided in two groups (adolescent and young adult patients), no significant difference in prevalence and features of the different phenotypes was observed.

CONCLUSION

In this cohort of adolescent and young adult women with PCOS, the progression of age does not change the prevalence and the features of main PCOS phenotypes. It suggests that the Rotterdam criteria might be used also in adolescents, at least in those with 2 or more years of gynecological age, for the diagnosis of PCOS.

Investigating the Safety and Efficacy of Platelet-Rich Plasma (PRP) Treatment for Female Androgenetic Alopecia: Review of the Literature

Background: female androgenetic alopecia (FAGA) is a common cause of non-scarring alopecia in women, affecting approximately 40% of women by age 50, bearing a significant psychosocial burden on affected patients. Platelet-rich plasma (PRP) has been widely investigated as a potential effective treatment for several dermatological conditions, including male androgenetic alopecia (MAGA). However, few studies have been conducted focusing on the use of PRP in FAGA. The aim of this review was to identify reports that investigated the use of PRP for the treatment of FAGA. Methods: Electronic databases of MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) from inception to September 2020 have been searched using different combinations of the following terms: “androgenetic alopecia,” “FAGA,” “female pattern hair loss,” “platelet-rich fibrin,” “platelet-rich plasma,” and “PRP”. Results and conclusions: Eight (n = 8) clinical studies consistent with our research were identified. A total of 197 subjects has been enrolled in the included studies. All of them were adult female patients (mean age: 38.9) affected by female pattern hair loss. PRP is a well-tolerated procedure which showed promising results in males-only and mixed populations of AGA patients. PRP showed to produce high levels of satisfaction and improvement in the quality of life in patients affected by FAGA. In the light of this evidence, PRP may be proposed in patients who did not respond or did not tolerate topical minoxidil, as well as in combination with topical and oral treatments.

The Diagnostic Value of Serum Ferritin for Telogen Effluvium: A Cross-Sectional Comparative Study

Purpose

This study aimed to explore the relationship between serum ferritin levels and telogen effluvium.

Patients and Methods

A total of 193 telogen effluvium patients and 104 female androgenetic alopecia patients were included. We collected the test result of serum ferritin levels, compared with the results of 183 healthy subjects. Receiver Operator Characteristic curves were generated to assess the potential diagnostic value of serum ferritin in telogen effluvium patients.

Results

The serum ferritin in telogen effluvium patients were significantly lower than that in the healthy control group (P = 0.000) or female androgenetic alopecia patients (P =0.000). Patients with lower serum ferritin levels got high odds to have telogen effluvium. The areas under the Receiver Operator Characteristic curve of serum ferritin levels were 0.735 and 0.645 for distinguishing telogen effluvium patients from healthy control subjects or female androgenetic alopecia patients.

Conclusion

Serum ferritin could be a potential biomarker for clinical diagnosis of telogen effluvium.

Cosmetic Endocrinology

Cosmetic endocrinology treats endocrine pathophysiologies to improve cosmetically bothersome physical exam findings for the patient. Here we review the general cosmetic changes in PCOS with an emphasis on targeted cosmetic medical therapies.

Is There Any Association Between Clinical and Biochemical Hyperandrogenism in Women With Female Pattern Hair Loss?

Background

The exact association between clinical and biochemical hyperandrogenism (HA) is heterogeneous and cannot be ascertained, especially in normoandrogenic women.

Objectives

Evaluate any association between clinical phenotypes and biochemical parameters of HA in premenopausal women with female pattern hair loss (FPHL).

Materials and methods

A cross-sectional observational study on 362 women, who were assessed for general characteristics, the different FPHL severities by Sinclair's score, hirsutism by modified Ferriman-Gallwey (mFG) score. Evaluation for biochemical HA included total, calculated free and bioavailable testosterone (TT), free testosterone (FT), and bioavailable testosterone (BT), respectively, and dehydroepiandrosterone sulfate. The variables of clinical HA were FPHL, hirsutism, and acne.

Results

The enrolled young premenopausal women's age range was (14-47 years). Around 78% were overweight or obese women. Eighty-percent of women had a mild FPHL, with a median of three years, where 2/3 of women had a duration <3 years with no significant relationship to FPHL severity. About 73% of women had either a mild to moderate hirsutism, and around 16% had acne. The biochemical HA was confirmed in around 52% of women (n=188), who show high levels of calculated FT. The calculated BT is high in 78.5% of women (n=284). The means of HA's biochemical indicators were in their reference ranges or slightly above, with no specific change pattern with the corresponding FPHL severity. None of these parameters had a significant relationship with the severity of FPHL. The FPHL duration was not affected by any presumed variable of clinical or biochemical HA.

Conclusions

FPHL severity was associated with other clinical HA signs like hirsutism and acne, but not to HA's biochemical parameter. Other parameters, like sex hormone-binding globulin (SHBG), and BMI, had no significant relation to the FPHL severity.

A safety evaluation of current medications for adult women with the polycystic ovarian syndrome not pursuing pregnancy

INTRODUCTION

The polycystic ovary syndrome (PCOS) is a very prevalent disorder in premenopausal women. Cardiovascular risk factors cluster in these patients, raising concern about the safety of the drugs commonly used to ameliorate symptoms of androgen excess in in this population at risk of cardiovascular morbidity.

AREAS COVERED

This review summarizes the clinical efficacy and safety profiles of drugs commonly used for the management of hyperandrogenic symptoms and endometrial protection in adult women with PCOS who do not seek pregnancy.

EXPERT OPINION

Antiandrogenic drugs usually used in adult women with PCOS carry a low risk of severe side effects. In spite of the cardiovascular risk profile of women with PCOS, and that individualized risk assessment is of paramount importance, there is no solid evidence supporting that the use of combined oral contraceptives in these women increases the risk of cardiovascular or thromboembolic events compared with the general population. However, virtually all these drugs are used in an off-label fashion. Large, high-quality studies addressing the long-term safety of pharmacological treatments in women with PCOS are definitely needed.

Evaluation of efficacy of QR 678 and QR678 neo hair growth factor formulation for the treatment of female pattern alopecia in patients with PCOS-A prospective study

BACKGROUND

Hair is an essential identity of women. Femininity, sexuality, attractiveness, and personality are symbolically linked to a woman's hair. Female pattern hair loss is found in 20%-30% of patients with polycystic ovary syndrome (PCOS).

AIM

The aim of the present study was to evaluate the efficacy of QR678^® and QR678 Neo^® therapy in the treatment of female alopecia with PCOS.

METHOD

A total of 20 females diagnosed with PCOS in the age 25-50 years, with complaints of female pattern alopecia with Ludwig, grades I, and II were selected for the study. At each visit, 1.5 ml solution of QR678^® was injected in the scalp skin of patients. A total of eight sessions were performed at an interval of 3 week each. All the patients were evaluated with standard global photography at baseline, 4th and 8th session, and 2 months after 8th session.

RESULT

Marked improvement was seen in the global photographic assessment score (mean = 8) which was maintained for over 1 year. In videomicroscopic assessment, after four sessions the patients had 8.07 fewer vellus hair, 6.07 more terminal hair, and average hair shaft diameter was 0.82 μm wider. After eight sessions, they had 11.66 fewer vellus hair, 13.77 more terminal hair, and hair shaft diameter was 2.86 μm wider than at baseline.

CONCLUSION

Intra-dermal injections of QR 678^® hair growth factor formulation is an effective option for female pattern alopecia with PCOS. This is the first of its kind study using QR678^® and QR678 Neo^® in PCOS patients.

Hormonal Effects on Hair Follicles

The hair cycle and hair follicle structure are highly affected by various hormones. Androgens—such as testosterone (T); dihydrotestosterone (DHT); and their prohormones, dehydroepiandrosterone sulfate (DHEAS) and androstendione (A)—are the key factors in terminal hair growth. They act on sex-specific areas of the body, converting small, straight, fair vellus hairs into larger darker terminal hairs. They bind to intracellular androgen receptors in the dermal papilla cells of the hair follicle. The majority of hair follicles also require the intracellular enzyme 5-alpha reductase to convert testosterone into DHT. Apart from androgens, the role of other hormones is also currently being researched—e.g., estradiol can significantly alter the hair follicle growth and cycle by binding to estrogen receptors and influencing aromatase activity, which is responsible for converting androgen into estrogen (E2). Progesterone, at the level of the hair follicle, decreases the conversion of testosterone into DHT. The influence of prolactin (PRL) on hair growth has also been intensively investigated, and PRL and PRL receptors were detected in human scalp skin. Our review includes results from many analyses and provides a comprehensive up-to-date understanding of the subject of the effects of hormonal changes on the hair follicle.

Female pattern hair loss: A comprehensive review

Female pattern hair loss is a common form of hair loss in women that increases in incidence with age. The etiology is unknown with numerous factors identified that influence its onset. Female pattern hair loss may be viewed as a marker for an increased risk of cardiovascular and metabolic disease. New treatments include microneedling, low-level laser therapy, and autologous fat transfer. This article focuses on the pathophysiology, diagnosis, systemic associations, and current treatments for female pattern hair loss, which is the most common cause of alopecia in women.

Current treatment for polycystic ovary syndrome: focus on adolescence

Polycystic ovary syndrome (PCOS) is the most frequent endocrine disorder in women and it is associated with an increased rate of infertility. Its etiology remains largely unknown, although both genetic and environmental factors play a role. PCOS is characterized by insulin resistance, metabolic disorders and low-grade chronic inflammation. To date, the treatment of PCOS is mainly symptomatic and aimed at reducing clinical signs of hyperandrogenism (hirsutism and acne), at improving menstrual cyclicity and at favoring ovulation. Since PCOS pathophysiology is still largely unknown, the therapeutic interventions currently in place are rarely cause-specific. In such cases, the therapy is mainly directed at improving hormonal and metabolic dysregulations typical of this condition. Diet and exercise represent the main environmental factors influencing PCOS. Thus, therapeutic lifestyle changes represent the first line of intervention, which, in combination with oral contraceptives, represent the customary treatment. Insulin resistance is becoming an increasingly studied target for therapy, most evidence stemming from the time-honored metformin use. Relatively novel strategies also include the use of thiazolidinediones and GLP1-receptor agonists. In recent years, a nutraceutical approach has been added to the therapeutic toolkit targeting insulin resistance. Indeed, emerging data support inositol and alpha-lipoic acid as alternative compounds, alone or in combination with the aforementioned strategies, with favorable effects on ovulation, insulin resistance and inflammation. Nevertheless, additional studies are required in adolescents, in order to assess the effectiveness of diet supplements in preventing negative impacts of PCOS on fertility in adult age. This review focuses on the main therapeutic options for PCOS to date.

Female Androgenetic Alopecia: An Update on Diagnosis and Management

Female androgenetic alopecia (FAGA) is a common cause of non-scarring alopecia in women. The onset may be at any age following puberty and the frequency increases with age. Clinically, it shows a diffuse hair thinning over the central scalp, while the frontal hairline is usually retained. FAGA can have a significant psychological impact, leading to anxiety and depression. For this reason, early diagnosis is very important to stop the progression of the disease. The sex hormonal milieu is the main pathogenetic mechanism studied in FAGA. The role of androgens is not clearly defined and only one-third of women with FAGA show abnormal androgen levels. Endocrinological diseases with hyperandrogenism associated with FAGA comprise polycystic ovarian syndrome (PCOS), hyperprolactinemia, adrenal hyperplasia and, rarely, ovarian and adrenal tumours. Usually the diagnosis of FAGA is made clinically. A complete clinical examination and a blood examination can reveal other signs of hyperandrogenism. Trichoscopy shows the typical hair miniaturization. A scalp biopsy can be useful when the clinical evaluation does not provide a definitive diagnosis or when cicatricial alopecias with hair loss in the distribution of FAGA or alopecia areata are suspected. FAGA is a slowly progressive disease. The goal of therapy is to stop the progression and to induce a cosmetically acceptable hair regrowth. The most important drugs are topical minoxidil and oral anti-androgens. The purpose of this review is to provide an update on FAGA and to create a guideline on diagnosis and management of this frequent hair disease, not always easily recognizable from cicatricial alopecias with a similar distribution.

Association of Perforin and Granzyme-B Levels with Hyperandrogenism in Polycystic Ovary Syndrome: A Case-Control Study

BACKGROUND AND OBJECTIVE

Polycystic ovary syndrome (PCOS) is shown to be associated with hyperandrogenemia and has some features such as cytotoxic T-cells activation and release of perforin and granzyme-B. Present work was aimed to investigate the relation of perforin and granzyme-B to androgenic state in PCOS.

MATERIALS AND METHODS

Forty three PCOS and 40 control women were recruited. After recording demographic data, sex hormone status and cardiovascular disease (CVD) risk factors were evaluated. Perforin and granzyme-B levels were measured using sandwich ELISA kits.

RESULTS

Sex hormone binding globulin (SHBG) levels were lower in patients. Luteinizing hormone (LH), free testosterone (FT), dehydroepiandrosterone sulfate (DHEA-S), free androgen index (FAI), perforin and granzyme-B values were higher in PCOS group. Perforin and granzyme-B were positively correlated with FT and FAI and with each other in PCOS group. In patients, granzyme-B and perforin were related with FT and FAI, respectively.

CONCLUSION

The results of present study together with evidences about the release of pro-inflammatory cytokines in insulin resistance, CVD and PCOS suggest that perforin/granzyme-B may be involved in interactions of sex hormones system in PCOS patients.

Hyperprolactinaemia

Hyperprolactinaemia is one of the most common problems in clinical endocrinology. It relates with various aetiologies (physiological, pharmacological, pathological), the clarification of which requires careful history taking and clinical assessment. Analytical issues (presence of macroprolactin or of the hook effect) need to be taken into account when interpreting the prolactin values. Medications and sellar/parasellar masses (prolactin secreting or acting through “stalk effect”) are the most common causes of pathological hyperprolactinaemia. Hypogonadism and galactorrhoea are well-recognized manifestations of prolactin excess, although its implications on bone health, metabolism and immune system are also expanding. Treatment mainly aims at restoration and maintenance of normal gonadal function/fertility, and prevention of osteoporosis; further specific management strategies depend on the underlying cause. In this review, we provide an update on the diagnostic and management approaches for the patient with hyperprolactinaemia and on the current data looking at the impact of high prolactin on metabolism, cardiovascular and immune systems.
