Abstract

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.

Introduction

Female pattern hair loss (FPHL) is the most common nonscarring diffuse hair loss disorder of a characteristic pattern in reproductive age women, with an uncertain relationship with androgens [1-3]. The main histopathological changes involve the hair follicles' miniaturization, with a consequent decline in hair density at different scalp regions, especially the scalp [1]. All phenotypic presentations of FPHL involve the bitemporal and vertex region in different severities. The anterior hair implantation line, frontal accentuation, and the degree of vertical baldness determine the severity of the presentation [1-3].

The study's objective was to evaluate any possible association between hyperandrogenism's clinical phenotype and biochemical parameters in premenopausal women with FPHL.

Materials and methods

A cross-sectional observational study on (362) women with FPHL of different degrees attended Faiha Specialized Diabetes Endocrine and Metabolism Center (FDEMC), Basrah. Initially, there were 582 women with the complaint of hair fall. Enrollment and exclusion criteria are illustrated in Figure 1.

Figure 1. Flow chart of the inclusion and exclusion criteria.

Figure 1

These women were either referred by gynecologists, dermatologists, internists, or self-presented directly seeking medical attention for frequent hair fall. These women were initially assessed for:

· General demographic characteristics like age, marital status, weight, and body mass index (BMI).

· Medical history in complaint-directed approach.

· Full past-medical history, gynecological, and any drug history, with relevant family history.

· Scalp examination for assessment of FPHL severity.

· Evaluation of the clinical characteristics by Sinclair's score for assessing FPHL severity modified Ferriman-Gallwey (mFG) score for hirsutism, and acne by direct clinical examination.

· Androgens evaluation included TT, sex hormone-binding globulin (SHBG), calculated FT, calculated bioavailable testosterone (BT), and DHEA-S.

Clinical HA is the presence of any cutaneous features of HA, while biochemical HA is the presence of elevated of at least one serum androgen [4].

We used Sinclair's score to assess the FPHL grades from minimal FPHL (grade 1) to severe (grade 5) FPHL [5]. The mFG score for hirsutism assessment works by the nine areas’ roles. The score of each one ranges from 1 to 4 according to the hair distribution severity. Scores ≤8/36 is the currently accepted figure for Middle-Eastern women, including Iraqi women. The hirsutism severity was graded according to (mFG) to mild (mFG score≤15), moderate (mFG score 6-25), and severe hirsutism (mFG score >25), or having no hirsutism (mFG score≤8) [6].

The variables of clinical HA which were used in this study were FPHL, hirsutism, and acne. The variables of biochemical HA were TT, FT, BT, and DHEA-S [6].

Laboratory testing

For regularly menstruating women, all hormonal investigations were performed during the first seven days of the menstrual cycle. The hormonal workup for women with amenorrhea or oligomenorrhea can be performed on any day. Early morning venous sample after at least eight hours of overnight fasting is required initially. Ten milliliters of venous blood were collected and kept in a gel tube, then centrifuged at 4100 xg by NUVE-NF 800. 

The TT, SHBG, DHEA-S were assessed using electrochemiluminescence by Roche Cobas e411 Analyzer (Germany) with standardized mean values of TT (0.52-1.60 nmol/L), for SHBG (18-86 nmol/L), and age-specific DHEA-S ranges (Appendix A.1). To calculate FT and BT, we used the method set by Vermeulen et al. [7].

Statistical analysis

We used IBM SPSS Statistics for Windows-Version 26 (IBM Corp., Armonk, NY) for the analysis of different variables. The study used the mean±standard deviation, median±standard error, and frequency (%) for data expression. For continuous variables evaluation, we compared the means using One-Way Analysis of Variables (ANOVA), while for categorical variables evaluation, the Chi-squared test was used. We used Boxplots to demonstrate the different relationships at (p ≤ 0.05) and (95% CI).

Results

The study’s enrollment criteria were set strictly to ensure the diagnostic accuracy for the FPHL as a sole cause for hair fall in the enrolled 362 premenopausal women (Figure 1).

All the enrolled women were young premenopausal, with an age range of (14-47 years). Around 78% of the enrolled women (n=283) had a high BMI (either overweight or obese), with a mean BMI of (30.88±7.11 kg/m2). A mild form of FPHL was observed in 79.3% of the women (n=287), for a mean duration of (3.45±2.69 years), and about two-thirds of women had a duration less than three years, although this has no significant relationship towards the degree of the FPHL (Tables 1, 2).

Evaluation of clinical HA was done by assessment of both hirsutism and acne. The mean mFG score was in the range of mild hirsutism, with most enrolled women (≈73%) having either a mild to moderate degree of hirsutism. A small number of women had acne and FPHL (n = 57), representing 15.7% of cases.

All the principal biochemical indicators for HA (TT, calculated FT, calculated BT, and DHEA-S) were in the reference or slightly above the reference ranges. The biochemical HA was confirmed in 51.9% of women (n = 188), who showed high levels of calculated FT. The calculated BT was high in 78.5% of the enrolled women (n=284). The mean level of SHBG was in the normal ranges, with only 61 women (16.9%) had low SHBG.

Presentation with different hirsutism and acne severities had a significant relationship to the FPHL degree, although different patients fell in varying severities for clinical HA. Figure 2.A illustrated the significant step-up pattern in women with FPHL concerning the hirsutism degree, which was mirrored by the significant (within-group comparison) in One-way ANOVA. On post hoc analysis (in between groups), the difference between mild versus the moderate type of FPHL is highly significant (p < 0.001) for mild versus severe type FPHL (p = 0.006), and it was not significant (p = 0.179) between the moderate versus severe FPHL.

None of HA's biochemical parameters had a significant relationship to the FPHL severity. The mean values of the biochemical parameters of HA had no specific pattern of change with the FPHL severity (Figures 2.B-2.E). Other parameters, like SHBG and BMI, had no significant relation to the FPHL severity (Table 2). The FPHL duration was not affected by any presumed variable of clinical or biochemical HA (Table 3).

Discussion

The evaluation of the association between clinical and biochemical HA in women with FPHL required two pivotal steps; the verification of association between the different clinical HA parameters and with different parameters of biochemical HA. All the possible confounders that might alter the androgen level or change the subjective evaluation of clinical HA had been excluded.

All the enrolled women were premenopausal, with an age distribution similar to other studies [4,8-11]. This study's weight distribution pattern was more prevalent towards overweight and obesity, with no significant relationship to the FPHL severity. These BMI figures are similar to other international studies [4,8,9,11,12]. However, they described different significance profiles of BMI towards different clinical HA signs due to different selection criteria from our study.

The mean Sinclair’s score of the cohort was (2±1), and represented a mild FPHL. Only 20.7% of women (n=75) had moderate to severe FPHL. The relationship between the FPHL duration and severity was not significant, even with the long mean duration of FPHL. Fattah et al. [13] described the absence of any significant association between the duration and severity of FPHL in 60 women but with a longer FPHL duration (7.56±3.5) versus (3.45±2.69) years in this study.

The other two signs of clinical HA, in addition to FPHL chosen in this study, were hirsutism and acne. It was noteworthy that not all women with FPHL had other clinical signs of HA, i.e., one-fifth of women were hirsutism-free, and more than 80% of women were acne-free. The significant correlation between FPHL and hirsutism severity was seen in Figure 2A, which described the population distribution and the different median mFG values. The post hoc analysis showed significant relationships between mild versus moderate and severe FPHL, unlike the relationship between moderate and severe types.

Hirsutism results from the interplay of the systemic and local androgens levels versus selective sensitivity and response of the pilosebaceous units' to androgens expression [14,15]. The fact that explains the limited indirect relationship between androgen level and the hirsutism severity and why the hirsutism does not always indicate hyperandrogenemia [15-17].

Considering acne as a reliable sign of clinical HA is controversial, given the previous observations for many normoandrogenic women with different acne severities, and the lack of significant direct or causal correlation between hyperandrogenemia and acne [18], which may be attributed to the selective sebum production by the pilosebaceous unit [19]. This might explain the significant association between acne and the FPHL severity in 57 women, compared to 305 women with FPHL who were acne-free, although both signs are androgen-mediated.

The FPHL duration had no significant effect on the presentation with hirsutism or acne, which could not be attributed to prolonged exposure to hyperandrogenemia, given that more than two-thirds of the cohort were normoandrogenic. The long duration may also be justified by the phenotypic heterogeneity of other clinical HA signs that urge the women to seek medical attention.

About one-third of women had high TT. We had a higher percentage of hyperandrogenism when considering the calculated FT and BT as a sole indicator of HA, with different serum-binding proteins ability [16].

There was no significant relationship between any variables of biochemical HA to FPHL severity or duration. These findings are comparable to many studies, which consider the FPHL a reliable marker for clinical HA, but not chemical HA [4,8,16].

The exact association between clinical and biochemical HA is heterogeneous [20], especially in normoandrogenic women, where genetic predisposition may play an extra role in peripheral androgen sensitization [2]. This might explain the lack of significant effect of biochemical HA parameters on the FPHL severity.

In this study, although the mean DHEA-S was normal for the enrolled age ranges, one-fifth of women had high DHEA-S. DHEA-S is a valuable marker for adrenal androgen production and activity. A normal serum DHEA-S level necessarily excludes the adrenals as HA source [21]. It has been recommended that FT be used only in patients with clinical HA with normal TT and DHEA-S [21]. DHEA-S does not bind serum proteins and does not change with any medical condition affecting them, and even it does not affect during menses [22]. Although the menstrual cycle does not affect SHBG significantly, as recommended by other authors [23].

We had four women with high DHEA-S as the sole circulating androgen, representing around 1% of women. Azziz et al. recommended against the overinterpretation of DHEA-S, if it was the sole abnormality in women with HA [24].

The SHBG level and the number of women with low SHBG did not show any significant relationship with the severity and duration of FPHL. Vexiau et al. showed a reciprocal relation between the SHBG levels and the FPHL severity [25], which might be due to the lower binding affinity at lower SHBG [8,16].

The study had a number of limitations. Not all clinical HA signs were tested; women were not examined for clitoromegaly. We acknowledge the limitation of Sinclair's score and mFG and the absence of acne's objective score. The cross-sectional design could not differentiate accidental from the causal association of the variables and the outcome and limit the results' generalizability.

Conclusions

The FPHL was associated with other clinical HA signs like hirsutism and acne, but not to any biochemical HA parameter, i.e., there was no variable of biochemical HA that had a significant relationship to the FPHL severity. It was essential to perform an exhaustive clinical examination for women with milder phenotypes of HA because the severity was disproportional to androgen level.

Part I: Information Sheet

Introduction

We are a study group of FDEMC. We are trying to find the association between biochemical and clinical findings regarding abnormal hormonal patterns in women who have female pattern hair loss (FPHL or androgenetic alopecia). The FPHL is frequently encountered in our practice and may cause many aspects of your quality of life to be affected, especially your perception of your body image and your self-satisfaction. You will be free to participate in this study or not, and you must keep in mind that your decision will not affect our level of medical care that was proposed to be presented to you at any time by any means. You do not have to answer now; you will have satisfactory time to agree or not. You are not obliged to give us consent today, you have all the week-long to study the consent and give us the response in your next visit a week from now, during this period you are free to contact any one of the study group to ask about any aspect you found it peculiar and need discussion. Whatever your decision will be, it will not affect our level of medical services provided to you. Keep in mind that you can withdraw your consent at any time before the complete publication of the study, and you are not obliged to give us any reasons. Again this will not affect our medical decision regarding your management by any means. You may have no questions now, but during the study, you may have questions, feel free to inform us to answer them. Is this understandable to you?

Purpose of the research

FPHL or androgenetic alopecia is a common finding in many women during their reproductive life. It affects the quality of life of women in many aspects. We want to evaluate the association of the biochemical and clinical findings of increased androgen levels. Is this association valid to be considered? Does any woman with biochemical changes of hyperandrogenism have relevant clinical changes? Is this understandable to you?

Type of Research Intervention

After you agree to participate in the study, you will be interviewed by the head of the study group (Samih Abed Odhaib), who will interview you thoroughly by history and clinical examination. He will ask about many aspects of your life that you may find embarrassing or hard to talk about like your weight, marital relation, self-perception, body image satisfaction, and sex life. He will discuss the importance of every item individually upon your request. You can take your time during the interview and you may quit answering any of the questions as you wish. This will not affect medical decisions at all.

After that, two different endocrine nurse will examine your hair by preformed scale separately using the Sinclair scale, to evaluate the degree of FPHL. They will assess the degree of your hirsutism (excessive body hair in abnormal places on women's body) using the modified Ferriman-Galway Score.

. The two endocrine nurses will be blind to each other’s results, to increase the accuracy of the findings. You will be returned to (Samih Abed Odhaib) for the interpretation of the results, and to be sent for blood investigations according to the timing of the menstrual cycle. There will be investigations in the first week of the cycle, others at the middle, and others at the end of the cycle, each will give us a clue about the menstrual pattern of yours that may be related to your FPHL or not, do you understand this or not? You need any further explanation? Additional investigations to exclude any associated illness may be sent for you after your permission, they are not additional, or for research purposes, but they will be needed in individual cases. All investigations will be needed to be drawn early in the morning in the fasting status according to the guidelines on an exact day during the menstrual cycle. You will be given an appointment within a week's duration till the results of the investigation verified by the study group. The next week you will be interviewed again to discuss the results of your investigation or to complete the battery of investigations for your complaint.

The investigations may take up to a month to be completed according to the scientific recommendations and the timing of the menstrual cycle.

During all these times you can withdraw your approval at any time, and you can request any answer for any question from the study group, and this will not affect our medical decision and the amount and the quality of medical care that will be proposed to be given to you. Do you understand? Do you have any questions till now?

All the participants will be dealt with as (registration numbers), not by names during the study progress. To keep the data as secrete as possible. All information will be registered as numbers on the SPSS data sheet directly with no names, only the registration number at the FDEMC database.

Participant Selection

You are being invited to take part in this research because we feel that your experience with FPHL can contribute much to our understanding and knowledge of local health practices, and may help us to decrease the effect of this complaint in affected women. Is this understandable to you?

هذه الاستمارة تتكون من قسمين:

·         استمارة المعلومات ( لغرض مشاركة معلومات الدراسة معك)

·         شهادة الموافقة (ليتم التوقيع عليها في حال وافقت على المشاركة)

و سوف يتم اعطاؤك نسخة من موافقتك المسبقة

 

القسم الاول

المقدمة

نحن مجموعة بحثية دراسية في مركز الفيحاء التخصصي للسكري و الغدد الصم و الايض, نحاول ان نوجد العلاقة بين العلامات السريرية و نمط تغير الهرمونات المختلفة لدى النساء ممن لديهن تساقط الشعر الانثوي. نصادف في عملنا هنا الكثير من حالات تساقط الشعر الانثوي, و الذي يؤثر على نوعية حياتك من عدة نواح, و خصوصا لمستوى ادراك صورتك الجسدية و تصورك لجسمك و فيما لو كنت مقتنعة به.

 

توطئة

لك مطلق الحرية في الاشتراك بهذه الدراسة او لا, و اعلمي ان قرارك هذا لن يؤثر البتة على مستوى الخدمة التي من المفترض ان تقدم لك من قبلنا بأي مستوى او طريقة. ليس عليك الاجابة الان, لديك الوقت الكافي للموافقة من عدمها, لست مجبرة على اعطائنا هذه الاستمارة اليوم, لديك اسبوع تقريبا لدراسة هذه الاستمارة و اعطاءنا اجابتك بعد اسبوع من الان في اثناء زيارتك القادمة, و خلال هذه الفترة لك مطلق الحرية في الاتصال بأي من اعضاء المجموعة البحثية للسؤال عن اي جزئية تجدينها غامضة و تحتاج للنقاش. و أيا كان قرارك لن يؤثر على الخدمات الطبية المقدمة لك. و تذكري دائما انك تستطيعين سحب موافقتك هذه في اي وقت قبل النشر الكامل للدراسة و ليس عليك توضيح سبب ذلك بتاتا. و ذلك ايضا لن يؤثر على القرار الطبي برعايتك باي وسيلة.

من الممكن ان لا يكون لديك سؤال الان, لكن على مدى الدراسة من الممكن ان يكون لديك, تذكري انك حرة بالاتصال باي منا لإجابته, هل هذا مفهوم لك؟

 

الهدف من البحث

تساقط الشعر الانثوي هو مشكلة شائعة لكثير من النساء خلال حياتهن, و هو يؤثر على نواح كثيرة من نوعية حياتهن. نحن نريد ان نقيم الارتباط بين العلامات السريرية و المتغيرات البيوكيميائية لفرط هرمون الذكورة, و فيما لو كان هذا الارتباط صالحا لكي نعتبر بخصوصه, اي فيما لو كانت اي امرأة لديها تغيرات بيوكيميائية معينة لفرط الذكورة تصاحب العلامات السريرية؟ هل هذا مفهوم لك؟

نوع التداخل البحثي

بعد موافقتك الدخول في الدراسة, سيقوم الدكتور سامح عبد عذيب و هو رئيس المجموعة البحثية, بمقابلتك و الاستفسار عن التاريخ المرضي السابق و كذلك يقوم بالفحص السريري المناسب. سوف يقوم بالاستفسار عن عدة جوانب من حياتك و التي من الممكن ان تجديها محرجة و من الصعب ان تتكلمي بها او تفصحي عنها مثل وزنك, العلاقات الزوجية و الجنسية, واقتناعك بنفسك و صورتك لجسمك. سيقوم دكتور سامح عبد عذيب بشرح اهمية كل فقرة على حدة و لديك ما يكفي من الوقت للإجابة عن الاسئلة اثناء المقابلة, و التي من الممكن ان تتركي الاجابة عن اي سؤال كيفما تشائين, و لن يؤثر ذلك على قرارنا الطبي المستقبلي البتة.

بعد هذا ستقوم اثنتان من الممرضات المتخصصات بالغدد الصماء كل على حدة و بدون معرفة نتائج الواحدة للاخرى لزيادة دقة الفحوصات السريرية, بتقييم شعرك بواسطة مقياس سنكلير,  لتقييم شدة تساقط الشعر الانثوي. كما و ستقومان بتقييم فرط نمو الشعر في اماكن مختلفة من الجسم بواسطة المقياس المعدل لفيرمان و غالواي. تؤخذ هذه النتائج الى دكتور سامح عبد عذيب الذي سيقوم بتفسير النتائج لك, و ارسال التحاليل الخاصة حسب وقت الدورة الشهرية, حيث ان هنالك تحاليل في الاسبوع الاول لها, في اثناء منتصف الدورة و اخرى قبل نهايتها, و كل من هذه التحاليل تعطينا فكرة عن نظام الدورة الشهرية لك, و فيما لو كان يؤثر على تساقط الشعر الانثوي خاصتك او لا. هل تفهمين ذلك ام تحتاجين الى توضيح اكثر؟ من الممكن ان نقوم بعمل تحاليل اضافية لك لاستبعاد علل و امراض قد تكون مرتبطة بحالتك, و طبعا ذلك يتم بعد موافقتك, و هذه التحاليل الاضافية مهمة لحالتك و ليست لأغراض بحثية, انما قد نحتاجها في حالات منفردة معينة.

كل التحاليل المذكورة نحتاج سحبها صباحا و في حالة الصيام عن الاكل و الشرب في اليوم المحدد من الدورة الشهرية حسب التعليمات و القواعد المسبقة, و سيتم اعطاؤك موعدا خلال اسبوع لاستلام نتائج التحاليل بعد ان يتم تقييمها من قبل الفريق البحثي. ستتم مقابلتك مرة اخرى الاسبوع القادم لشرح نتائج التحاليل, وفيما لو احتجت تحاليل او فحوصات اضافية او لا حسب حالتك. قد تستمر الفحوصات لشهر كامل كي تكتمل حسب القواعد و التوجيهات العلمية المسبقة و حسب مواعيد الدورة الشهرية.

خلال هذا الوقت لك مطلق الحرية لسحب موافقتك على الانخراط في الدراسة بأي وقت, كما و يمكنك طلب الاجابة عن اي استفسار من اي من اعضاء الفريق البحثي, و لن يؤثر ذلك على كمية و نوعية العناية الطبية المقدمة المفترضة لك, هل تفهمين ذلك؟ هل لديك اي سؤال لحد الان؟

كل المنخرطات بالدراسة هذه, سيتم التعامل مع بيانتهن كرقم تسجيلي و ليس كأسماء خلال المراحل المختلفة للدراسة لحفظ السرية قدر المستطاع. كل البيانات ستسجل كجزء من برنامج احصائي حسابي يسمى SPSS مباشرة كأرقام تسجيلية مركزية لمركز الفيحاء التخصصي للسكري و الغدد الصماء و الايض و بدون اسماء ايضا.
