C<strong>on</strong>text and Objective: The efficacy <str<strong>on</strong>g>of</str<strong>on</strong>g> oral dehydroepiandroster<strong>on</strong>e (DHEA) in the treatment <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

atrichia pubis and psychological distress in young females with central adrenal insufficiency is<br />

unknown. Our study aimed to evaluate this therapy.<br />

Design and Patients: A total <str<strong>on</strong>g>of</str<strong>on</strong>g> 23 young females (mean age 18 yr, range 13–25) was enrolled in<br />

a double-blind randomized placebo-c<strong>on</strong>trolled trial. Inclusi<strong>on</strong> criteria were ACTH deficiency plus<br />

two or more additi<strong>on</strong>al pituitary deficiencies, serum DHEA less than 400 ng/ml, and pubertal stage<br />

more than B2. Exclusi<strong>on</strong> criteria were cerebral radiati<strong>on</strong> with more than 30 Gy, tumor remissi<strong>on</strong><br />

less than 1 yr, amaurosis, hypothalamic obesity, psychiatric disorders, and unstable horm<strong>on</strong>e medicati<strong>on</strong>.<br />

Interventi<strong>on</strong>: Patients were randomized to placebo (n 12) or 25 mg HPLC-purified DHEA/d (n <br />

11) orally for 12 m<strong>on</strong>ths after stratificati<strong>on</strong> into a n<strong>on</strong>tumor (n 7) and a tumor group (n 16).<br />

Main Outcome Measures: Clinical scoring <str<strong>on</strong>g>of</str<strong>on</strong>g> pubic hair stage was performed at 0, 6, and 12 m<strong>on</strong>ths<br />

(primary endpoint), and psychometrical evaluati<strong>on</strong> (Symptom Check-List-90-R and the Centre for<br />

Epidemiological Studies-Depressi<strong>on</strong> Scale) at 0 and 12 m<strong>on</strong>ths (sec<strong>on</strong>dary endpoint). Androgen<br />

levels and safety parameters were measured at 0, 6, and 12 m<strong>on</strong>ths; 24-h androgen urinary excreti<strong>on</strong><br />

rates were calculated at 0 and 12 m<strong>on</strong>ths.<br />

Results: In the placebo group, four patients dropped out because <str<strong>on</strong>g>of</str<strong>on</strong>g> recurrence <str<strong>on</strong>g>of</str<strong>on</strong>g> craniopharyngioma,<br />

manifestati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> type 1 diabetes, and change <str<strong>on</strong>g>of</str<strong>on</strong>g> residence (n 2); in the DHEA group, <strong>on</strong>e<br />

patient dropped out because <str<strong>on</strong>g>of</str<strong>on</strong>g> recurrent anxiety attacks. DHEA substituti<strong>on</strong> resulted in normalizati<strong>on</strong><br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> DHEA sulfate and androstanediol glucur<strong>on</strong>ide morning serum levels 2 h after drug intake<br />

(P 0.006), and <str<strong>on</strong>g>of</str<strong>on</strong>g> its 24 h urinary metabolite levels (P 0.0001), placebo had no effect. Morning<br />

serum levels <str<strong>on</strong>g>of</str<strong>on</strong>g> androstenedi<strong>on</strong>e increased in the DHEA group (P 0.02) but did not normalize. The<br />

DHEA group exhibited significant progress in pubic hair growth from Tanner stage I–III to II–V<br />

(mean: 1.5 stages), whereas the placebo group did not (relative risk 0.138; 95% c<strong>on</strong>fidence<br />

interval 0.021–0.914; P 0.0046). Importantly, eight <str<strong>on</strong>g>of</str<strong>on</strong>g> the 10 Symptom Check-List-90-R scores, including<br />

those for depressi<strong>on</strong>, anxiety, and interpers<strong>on</strong>al sensitivity, and the global severity index improved<br />

in the DHEA group in comparis<strong>on</strong> to the placebo group (P 0.048). DHEA was well tolerated.<br />

C<strong>on</strong>clusi<strong>on</strong>s: In adolescent girls with central adrenal insufficiency, daily replacement with 25 mg<br />

DHEA orally is beneficial: atrichia pubis vanishes, and psychological well-being improves<br />

significantly. (J Clin Endocrinol Metab 94: 1182–1190, 2009)<br />

ACTH deficiency causes a deficient supply <str<strong>on</strong>g>of</str<strong>on</strong>g> the adrenal horm<strong>on</strong>es<br />

cortisol and dehydroepiandroster<strong>on</strong>e (DHEA). Although<br />

replacement <str<strong>on</strong>g>of</str<strong>on</strong>g> cortisol is standard in endocrine care for<br />

children and adults, treatment <str<strong>on</strong>g>of</str<strong>on</strong>g> DHEA deficiency is still a matter<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> discussi<strong>on</strong> (1). Impaired health-related quality <str<strong>on</strong>g>of</str<strong>on</strong>g> life in adults<br />

with adrenal insufficiency was reported, suggesting insufficient replacement<br />

therapy (2). Such data are missing for childhood and<br />

adolescence.<br />

DHEA is a prohorm<strong>on</strong>e <str<strong>on</strong>g>of</str<strong>on</strong>g> androgens and estrogens, and by<br />

95% <str<strong>on</strong>g>of</str<strong>on</strong>g> adrenal origin (3). In early childhood, DHEA producti<strong>on</strong><br />

is low until it gradually starts to increase between 6 and 10 yr <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

age. This phenomen<strong>on</strong>, called adrenarche, is associated with expansi<strong>on</strong><br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> the adrenal z<strong>on</strong>a reticularis (3). Peak DHEA serum c<strong>on</strong>centrati<strong>on</strong><br />

is reached in women at about 24 yr <str<strong>on</strong>g>of</str<strong>on</strong>g> age, followed by<br />

a steady decline, down to around 20% <str<strong>on</strong>g>of</str<strong>on</strong>g> the peak value (4).<br />

DHEA and its sulfate ester, DHEA sulfate (DHEAS), are secreted<br />

in very large amounts, and are the endocrine steroids with<br />

the highest serum c<strong>on</strong>centrati<strong>on</strong> in humans. Many peripheral<br />

target tissues are able to c<strong>on</strong>vert DHEA into sex horm<strong>on</strong>es (5).<br />

While androgens in males are mainly produced in the testes independent<br />

from DHEA producti<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> the adrenals, androgens in<br />

females are to more than 75% c<strong>on</strong>versi<strong>on</strong> products <str<strong>on</strong>g>of</str<strong>on</strong>g> DHEA (6).<br />

Therefore, DHEA deficiency results in androgen deficiency in<br />

females (7). Childhood <strong>on</strong>set <str<strong>on</strong>g>of</str<strong>on</strong>g> complete adrenal insufficiency is<br />

regularly associated with atrichia pubis and lack <str<strong>on</strong>g>of</str<strong>on</strong>g> axillary hair<br />

in females because growth <str<strong>on</strong>g>of</str<strong>on</strong>g> sexual hair in females is completely<br />

dependent <strong>on</strong> the presence <str<strong>on</strong>g>of</str<strong>on</strong>g> the prohorm<strong>on</strong>e DHEA and its<br />

c<strong>on</strong>versi<strong>on</strong> product dihydrotestoster<strong>on</strong>e (8).<br />

Prospective l<strong>on</strong>g-term studies <strong>on</strong> the c<strong>on</strong>sequences <str<strong>on</strong>g>of</str<strong>on</strong>g> chr<strong>on</strong>ic<br />

DHEA deficiency with early <strong>on</strong>set do not exist. Randomized<br />

short-term studies in adults with adrenal insufficiency suggested<br />

a good safety pr<str<strong>on</strong>g>of</str<strong>on</strong>g>ile <str<strong>on</strong>g>of</str<strong>on</strong>g> DHEA at doses <str<strong>on</strong>g>of</str<strong>on</strong>g> 25–50 mg/d orally,<br />

which were able to normalize DHEA(S) serum levels in healthy<br />

c<strong>on</strong>trols after suppressi<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> the adrenal gland (9). Positive effects<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> DHEA <strong>on</strong> well-being and sexuality in adult females with<br />

adrenal insufficiency that were shown in the first c<strong>on</strong>trolled<br />

short-term study (10) were c<strong>on</strong>firmed in most <str<strong>on</strong>g>of</str<strong>on</strong>g> the following<br />

short-term studies (11–13) and in <strong>on</strong>e l<strong>on</strong>g-term study (14), but<br />

not in all studies (15). In pediatric patients there are two small<br />

unc<strong>on</strong>trolled case studies reported <strong>on</strong> DHEAS (instead <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

DHEA) therapy that suggested that this medicati<strong>on</strong> is able to<br />

induce pubarche in girls with adrenal insufficiency (7, 16). C<strong>on</strong>trolled<br />

studies in late childhood or adolescence do not exist at all.<br />

We hypothesized that medicati<strong>on</strong> with DHEA might be most<br />

useful and effective in females who are severely deficient <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

DHEA and at an adolescent age when DHEA(S) reaches its physiological<br />

serum peak. Here, we report the data observed in a<br />

randomized c<strong>on</strong>trolled double-blind study that included adoles-<br />

cent girls and young women at ages between 13 and 26 yr with<br />

severe DHEA deficiency due to central adrenal insufficiency.<br />

Subjects and Methods<br />

Subjects<br />

Adolescent girls and young women at ages between 13 and 26 yr with<br />

the diagnosis <str<strong>on</strong>g>of</str<strong>on</strong>g> central adrenal insufficiency were enrolled in the study.<br />

The clinicians who decided to take part in this study were asked to screen<br />

all their patients with a chr<strong>on</strong>ic endocrine disorder for eligibility. This<br />

screening was d<strong>on</strong>e in four pediatric endocrinology departments at university<br />

hospital clinics by pediatric endocrinologists who are known to<br />

have very good expertise in diagnosis and therapy <str<strong>on</strong>g>of</str<strong>on</strong>g> hypopituitarism.<br />

Eligibility criteria were a pubertal breast stage B3 or more according to<br />

Tanner, DHEAS serum levels less than 400 ng/ml in two independent<br />

measurements (DHEA deficiency), proven central adrenal insufficiency,<br />

presence <str<strong>on</strong>g>of</str<strong>on</strong>g> at least two additi<strong>on</strong>al pituitary horm<strong>on</strong>e deficiencies, and no<br />

planned changes in medicati<strong>on</strong> during the study. Exclusi<strong>on</strong> criteria were<br />

cranial irradiati<strong>on</strong> with more than 30 Gy, hypothalamic obesity syndrome,<br />

amaurosis, mental retardati<strong>on</strong>, psychosis, systemic diseases like<br />

chr<strong>on</strong>ic hepatopathy and heart disorders, diabetes mellitus and elevated<br />

liver enzymes, as well as durati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> remissi<strong>on</strong> from a cerebral tumor<br />

shorter than 12 m<strong>on</strong>ths.<br />

The group c<strong>on</strong>sisted <str<strong>on</strong>g>of</str<strong>on</strong>g> seven patients with c<strong>on</strong>natal and 16 with acquired<br />

hypopituitarism after resecti<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> a tumor <str<strong>on</strong>g>of</str<strong>on</strong>g> the sella regi<strong>on</strong>. The 16<br />

patients included 12 cases after surgery for a craniopharyngioma and four<br />

cases <str<strong>on</strong>g>of</str<strong>on</strong>g> other tumors <str<strong>on</strong>g>of</str<strong>on</strong>g> the sella regi<strong>on</strong> (in detail: two dysgerminomas, <strong>on</strong>e<br />

pituitary adenoma, and <strong>on</strong>e astrocytoma). All patients and parents <str<strong>on</strong>g>of</str<strong>on</strong>g> patients<br />

gave their written informed c<strong>on</strong>sent before enrollment.<br />

Study design<br />

This study was a randomized, double-blind, placebo-c<strong>on</strong>trolled, multicenter<br />

trial. We decided against the cross-over design for this study to<br />

avoid cross-over effects that were likely to occur. The study has been<br />

registered at www.clinicaltrials.gov. The trial was c<strong>on</strong>ducted in compliance<br />

with internati<strong>on</strong>al guidelines. The protocol was reviewed by the<br />

Ethics Committee <str<strong>on</strong>g>of</str<strong>on</strong>g> the Medical Faculty <str<strong>on</strong>g>of</str<strong>on</strong>g> Tuebingen and by the German<br />

Federal Institute for Drugs and Medical Devices. Adherence to good<br />

clinical practice in this multicenter trial was achieved by implementati<strong>on</strong><br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> a standardized protocol, an investigator’s brochure, an operati<strong>on</strong>al<br />

manual with detailed instructi<strong>on</strong>s <strong>on</strong> how to perform each assessment,<br />

data collecti<strong>on</strong> <strong>on</strong> case record forms, several investigators’ meetings before<br />

starting the trial reviewing all procedures and assessments, an initiati<strong>on</strong><br />

visit at each site by a m<strong>on</strong>itor assistant, and <strong>on</strong>going m<strong>on</strong>itoring<br />

throughout the study to maintain the quality <str<strong>on</strong>g>of</str<strong>on</strong>g> data collected. Patients<br />

were randomized to receive either placebo or DHEA at a dose <str<strong>on</strong>g>of</str<strong>on</strong>g> 25 mg<br />

<strong>on</strong>ce a day in the morning orally for 12 m<strong>on</strong>ths. Both drugs, DHEA and<br />

placebo, were supplied as a sterile powder in identical capsules that did<br />

not provide any informati<strong>on</strong> <strong>on</strong> its c<strong>on</strong>tent to the user.<br />

DHEA and placebo<br />

DHEA used was produced by Synopharm GmbH (Barsbüttel, Germany)<br />

as a highly pure (HPLC c<strong>on</strong>tent 100%) powder. This chemical<br />

was encapsulated and distributed by the Pharmacy <str<strong>on</strong>g>of</str<strong>on</strong>g> the Medical Faculty<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> the University Ulm, Germany. The placebo used was D-mannitol<br />

were counted at each visit.<br />

Efficacy assessment<br />

In the current trial, we tested the hypothesis that oral administrati<strong>on</strong><br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> 25 mg DHEA is able to promote impaired pubic hair growth (primary<br />

endpoint) and to decrease psychological distress (sec<strong>on</strong>dary endpoint 1),<br />

both caused by central adrenal insufficiency. In additi<strong>on</strong>, normalizati<strong>on</strong><br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> adrenal androgen levels in serum 2 h after drug intake and in a 24-h<br />

urine collecti<strong>on</strong> were tested (sec<strong>on</strong>dary endpoint 2). Efficacy measurements<br />

were performed at baseline, and at 6 and 12 m<strong>on</strong>ths during<br />

therapy.<br />

The primary outcome measure with respect to efficacy was the proporti<strong>on</strong><br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> patients with a change to a more mature pubic hair stage from<br />

baseline to m<strong>on</strong>th 12, as measured by Tanner stages. For clinical purposes,<br />

Tanner has separated the pubic hair development into five stages<br />

from stage PH1 (infantile) to stage PH5 (adult) (17) (Fig. 1). This staging<br />

is routinely used by pediatricians. All five clinical investigators involved<br />

are experienced pediatric endocrinologists who are very familiar with the<br />

staging <str<strong>on</strong>g>of</str<strong>on</strong>g> pubic hair according to Tanner.<br />

Sec<strong>on</strong>dary outcome measures were positive changes (calculated as<br />

the difference <str<strong>on</strong>g>of</str<strong>on</strong>g> each score) in well-being and mood from baseline to<br />

m<strong>on</strong>th 12 as measured by the German versi<strong>on</strong>s <str<strong>on</strong>g>of</str<strong>on</strong>g> the Symptom Check-<br />

List-90-R (SCL-90-R) and <str<strong>on</strong>g>of</str<strong>on</strong>g> the Centre for Epidemiological Studies-<br />

Depressi<strong>on</strong> Scale (CES-D). The SCL-90-R is a widely used, well-validated<br />

psychological status symptom inventory that measures the subjectively<br />

experienced distress by 90 given somatic and mental symptoms. The<br />

individual tested reports the symptoms experienced during the last 7 d.<br />

This inventory allows a multidimensi<strong>on</strong>al analysis and c<strong>on</strong>tains repeated<br />

measurements. The German versi<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> SCL-90-R is well established, and<br />

reference data for schoolchildren and adolescents are available (18, 19).<br />

The other test used, the CES-D, is <strong>on</strong>e <str<strong>on</strong>g>of</str<strong>on</strong>g> the most frequently used and<br />

well-validated self-report screening tool for depressive symptoms.<br />

toms during the preceding week. The German versi<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> the CES-D is<br />

well established, and reference data for schoolchildren and adolescents<br />

are available (20, 21).<br />

Additi<strong>on</strong>al sec<strong>on</strong>dary outcome measures were the change to normalizati<strong>on</strong><br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> serum androgen levels (DHEAS, androstenedi<strong>on</strong>e, testoster<strong>on</strong>e)<br />

2 h after drug intake and <str<strong>on</strong>g>of</str<strong>on</strong>g> the amount <str<strong>on</strong>g>of</str<strong>on</strong>g> urinary excreted androgens<br />

[DHEA, DHEA and M (16-hydroxylated downstream metabolites),<br />

5-androstene-3,17-diol (ADIOL), C19 (total androgen metabolites)].<br />

Serum samples were collected from the n<strong>on</strong>fasted patient in the morning<br />

before 1000 h during each visit (0, 6, and 12 m<strong>on</strong>ths), around 2 h after<br />

oral administrati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> DHEA at visits 6 and 12 m<strong>on</strong>ths. The samples<br />

were collectively assayed at the end <str<strong>on</strong>g>of</str<strong>on</strong>g> the trial to exclude changes <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

measurements due to interassay variability. Serum DHEAS levels were<br />

measured using an automated chemiluminescence assay system (Immulite;<br />

DPC Biermann GmbH, Bad Nauheim, Germany). Intraassay coefficients<br />

ranged from 4.8–8.8%. Total serum testoster<strong>on</strong>e was measured<br />

by solid-phase 125J RIA in unextracted serum (Coat-A-Count total testoster<strong>on</strong>e;<br />

Diagnostic Products Corp., Los Angeles, CA). Cross-reactivity<br />

to natural steroids was by far less than 1%, to 5-dihydrotestoster<strong>on</strong>e<br />

3%. The intraassay coefficient was 6.0% according to the manufacturer.<br />

Androstenedi<strong>on</strong>e serum levels were determined by Active Androstenedi<strong>on</strong>e<br />

RIA (Diagnostics Systems Laboratories, Sinsheim, Germany). Cross-reactivity<br />

to natural androgens is less than 0.33%. The intraassay coefficient<br />

was 5.6% according to the manufacturer. The measurements <str<strong>on</strong>g>of</str<strong>on</strong>g> androstanediol<br />

glucur<strong>on</strong>ide levels in serum were performed using androstanediol<br />

glucur<strong>on</strong>ide RIA DSL-6000 (Diagnostics Systems Laboratories).<br />

Intraassay coefficients range from 4.2–8.2%. Reference values for the<br />

horm<strong>on</strong>e assays used were taken from three references (22–24). Serum<br />

SHBG levels were determined using the Immulite 1000 SHBG assay<br />

(Immulite). Intraassay coefficients ranged from 4.1–7.7% according to<br />

the manufacturer.<br />

Urinary pr<str<strong>on</strong>g>of</str<strong>on</strong>g>iling was performed at 0 and 12 m<strong>on</strong>ths. Patients and<br />

parents received instructi<strong>on</strong> and written guidance to ensure compliance<br />

in the 24 h-urine collecti<strong>on</strong> that was performed at home by each participant<br />

before the visits. The urinary steroid pr<str<strong>on</strong>g>of</str<strong>on</strong>g>iles were determined using<br />

quantitative data produced by gas chromatography (GC)-mass spectrometry<br />

analysis according to the method described previously (25). In<br />

brief, free and c<strong>on</strong>jugated urinary steroids were extracted by solid-phase<br />

extracti<strong>on</strong>, and the c<strong>on</strong>jugates were enzymatically hydrolyzed. Thereafter,<br />

steroids were again recovered by solid-phase extracti<strong>on</strong> and derivatized<br />

to form methyloxime-trimethylsilyl ethers. GC was performed<br />

using an Optima-1 fused silica column (Machery-Nagel, Dueren, Germany)<br />

and helium as carrier gas. The GC (Agilent 6890 Series GC; Agilent<br />

7683 Series Injector; Agilent Technologies, Inc., Palo Alto, CA) was<br />

directly interfaced to a mass selective detector (Agilent 5973N MSD)<br />

operated in selected i<strong>on</strong> m<strong>on</strong>itoring mode.<br />

Daily urinary excreti<strong>on</strong> rates were determined for DHEA, ADIOL,<br />

and the sum <str<strong>on</strong>g>of</str<strong>on</strong>g> DHEA and its 16-hydroxylated downstream metabolites<br />

16-hydroxy-DHEA and 3,16,17-androstenetriol (DHEA<br />

and M), reflecting major adrenarchal secreti<strong>on</strong> products. Overall androgen<br />

metabolite excreti<strong>on</strong> (C19) was determined as the sum <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

androster<strong>on</strong>e, etiocholanol<strong>on</strong>e, ADIOL, DHEA, 16-hydroxy-<br />

DHEA, and 3,16,17-androstenetriol.<br />

Safety assessments<br />

The clinical assessment performed at every visit included physical<br />

examinati<strong>on</strong> with measurement <str<strong>on</strong>g>of</str<strong>on</strong>g> height, weight, blood pressure, serum<br />

chemistry, and complete blood count. We especially looked for the occurrence<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> acne and <str<strong>on</strong>g>of</str<strong>on</strong>g> hirsutism, which was quantified by the score<br />

proposed by Ferriman and Gallwey (26). Adverse events were m<strong>on</strong>itored<br />

and recorded throughout the study according to Good Clinical Practice<br />

guidelines.<br />

Sample size<br />

We estimated that the probability for a change <str<strong>on</strong>g>of</str<strong>on</strong>g> the pubic stage<br />

would be 5% in the placebo group and 50% in the DHEA group, according<br />

to the data from two small unc<strong>on</strong>trolled case studies <strong>on</strong> DHEAS


J Clin Endocrinol Metab, April 2009, 94(4):1182–1190 jcem.endojournals.org 1185<br />

(7, 16). Based <strong>on</strong> an -error level <str<strong>on</strong>g>of</str<strong>on</strong>g> 5% and -error level <str<strong>on</strong>g>of</str<strong>on</strong>g> 20% (<strong>on</strong>esided<br />

testing) to detect a change to a higher pubic stage, 12 patients were<br />

required for each study group. To compensate for a dropout rate <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

10–20%, we planned to include 30 patients. Actually, recruitment was<br />

poorer than expected because some hospitals initially involved decided<br />

not to take part in the study because <str<strong>on</strong>g>of</str<strong>on</strong>g> the inability to manage the<br />

workload associated with this study. For partial compensati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> this<br />

event, the age range for inclusi<strong>on</strong> was extended from 13–23 yr to 13–26<br />

yr by the amendment No. 1 <str<strong>on</strong>g>of</str<strong>on</strong>g> the study protocol from April 2003.<br />

Allocati<strong>on</strong> sequence<br />

To achieve balance in respect to the medical history <str<strong>on</strong>g>of</str<strong>on</strong>g> the patients,<br />

randomizati<strong>on</strong> was stratified into a “tumor group” defined by a medical<br />

history <str<strong>on</strong>g>of</str<strong>on</strong>g> a cerebral tumor <str<strong>on</strong>g>of</str<strong>on</strong>g> the sella regi<strong>on</strong> (in remissi<strong>on</strong>), and a “n<strong>on</strong>tumor<br />

group” defined by c<strong>on</strong>natal hypopituitarism and absence <str<strong>on</strong>g>of</str<strong>on</strong>g> a<br />

history <str<strong>on</strong>g>of</str<strong>on</strong>g> a cerebral tumor. The allocati<strong>on</strong> sequence was defined by two<br />

computer-generated randomizati<strong>on</strong> lists (<strong>on</strong>e for each group) that were<br />

set up by a statistician <str<strong>on</strong>g>of</str<strong>on</strong>g> the Department <str<strong>on</strong>g>of</str<strong>on</strong>g> Medical Biometry Tuebingen,<br />

and were given to the pharmacy at the University <str<strong>on</strong>g>of</str<strong>on</strong>g> Ulm. These lists<br />

ensured that members <str<strong>on</strong>g>of</str<strong>on</strong>g> both groups had an equal probability to get<br />

DHEA or placebo (1:1). Independent pharmacists (University <str<strong>on</strong>g>of</str<strong>on</strong>g> Ulm,<br />

to these lists whose c<strong>on</strong>tent was not available for the researchers. The<br />

researchers were completely blinded for the c<strong>on</strong>tent <str<strong>on</strong>g>of</str<strong>on</strong>g> the capsules allocated<br />

to each patient from the time <str<strong>on</strong>g>of</str<strong>on</strong>g> allocati<strong>on</strong> until the end <str<strong>on</strong>g>of</str<strong>on</strong>g> the<br />

Statistical analysis<br />

The primary endpoint was the change in pubic hair stage in the treatment<br />

group compared with the placebo group. The efficacy <str<strong>on</strong>g>of</str<strong>on</strong>g> the therapy<br />

was statistically evaluated using the Cochran-Mantel-Haenszel- 2<br />

test (27), including the estimati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> the relative risk, its 95% c<strong>on</strong>fidence<br />

interval, and two-sided P values. Analyses <str<strong>on</strong>g>of</str<strong>on</strong>g> changes in the psychological<br />

scores and changes in serum and urinary horm<strong>on</strong>e levels were performed<br />

using the two-sided Wilcox<strong>on</strong> test. All analyses were performed<br />

were lost at follow-up because <str<strong>on</strong>g>of</str<strong>on</strong>g> change in residence<br />

after 6 m<strong>on</strong>th therapy. The remaining 18 patients completed<br />

the trial.<br />

Recruitment was started in January 2004 and ended in March<br />

2006. All 23 patients attended the clinic at baseline after recruitment<br />

and randomizati<strong>on</strong>. There were 21 patients seen at the 6<br />

m<strong>on</strong>th visit, and 18 completed the trial at the 12 m<strong>on</strong>th visit. The<br />

last patient had her 12-m<strong>on</strong>th visit in April 2007.<br />

Study populati<strong>on</strong><br />

Baseline characteristics <str<strong>on</strong>g>of</str<strong>on</strong>g> the randomized study participants<br />

are shown in Table 1. The groups were well balanced<br />

with respect to age, weight, tumor and radiati<strong>on</strong> history, presence<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> additi<strong>on</strong>al pituitary horm<strong>on</strong>e deficiencies, doses <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

horm<strong>on</strong>es substituted, and pubic hair stage. All 23 patients<br />

had hypog<strong>on</strong>adotropic hypog<strong>on</strong>adism and were substituted<br />

with sex steroids. The <strong>on</strong>ly clinical characteristic that was<br />

different between the two groups was height (the placebo<br />

group was taller), which was presumably <str<strong>on</strong>g>of</str<strong>on</strong>g> no clinical relevance<br />

for this study.<br />

The analyses <str<strong>on</strong>g>of</str<strong>on</strong>g> the primary and sec<strong>on</strong>dary outcome measures<br />

involved all patients who took part in the 6-m<strong>on</strong>th visit and<br />

excluded the two patients who were withdrawn from active<br />

treatment before the first assessment <str<strong>on</strong>g>of</str<strong>on</strong>g> efficacy. Treatment compliance<br />

was good; the counts <str<strong>on</strong>g>of</str<strong>on</strong>g> unused capsules were in good<br />

agreement to the expected numbers. In additi<strong>on</strong>, no relevant<br />

violati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> the study protocol was noted.<br />

Primary efficacy outcome<br />

The chr<strong>on</strong>ological change <str<strong>on</strong>g>of</str<strong>on</strong>g> the pubic hair stage in each individual<br />

treated is shown in Fig. 2. The DHEA group exhibited<br />

a significant progress in pubic hair growth from Tanner stage<br />

I–III to II–V (mean: 1 1 ⁄2 stages), whereas the placebo group<br />

did not (mean: 0stages) (P0.0046). Progress in pubic hair stage<br />

was observed in nine <str<strong>on</strong>g>of</str<strong>on</strong>g> 10 patients in the DHEA group, but <strong>on</strong>ly<br />

in three <str<strong>on</strong>g>of</str<strong>on</strong>g> 11 patients in the placebo group (relative risk: 0.138;<br />

95% c<strong>on</strong>fidence interval 0.021–0.914; P 0.0046). In the<br />

DHEA group, five adolescents reached the mature pubic hair<br />

stages IV and V, whereas <strong>on</strong>ly <strong>on</strong>e individual did in the placebo<br />

group.<br />

Sec<strong>on</strong>dary efficacy outcomes<br />

The psychometric measurement <str<strong>on</strong>g>of</str<strong>on</strong>g> psychological distress using<br />

the SCL-90-R at baseline and after 12 m<strong>on</strong>th therapy gave<br />

different results in the DHEA group when compared with the<br />

placebo group. We evaluated the psychological distress at baseline<br />

and after 12 m<strong>on</strong>th therapy, and calculated the differences<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> the scores observed. The values are<br />

shown in Table 2. At the start, the DHEA<br />

group scored higher than the placebo<br />

group in all scales, but differences were not<br />

significant. In all 10 scores, the DHEA<br />

group improved during therapy, whereas<br />

the placebo group worsened. These<br />

changes were significantly different in<br />

eight <str<strong>on</strong>g>of</str<strong>on</strong>g> 10 scores, including the global severity<br />

index, which is the central integrating<br />

score <str<strong>on</strong>g>of</str<strong>on</strong>g> this psychometric test. Baseline<br />

and outcome scores <str<strong>on</strong>g>of</str<strong>on</strong>g> both groups<br />

were within the normal range observed in<br />

the reference populati<strong>on</strong> (19).<br />

We used an additi<strong>on</strong>al psychometric instrument,<br />

the German versi<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> the CES-D,<br />

to observe the presence <str<strong>on</strong>g>of</str<strong>on</strong>g> depressive symptoms<br />

in each patient treated. The effects <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

the treatment were evaluated by comparis<strong>on</strong><br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> changes in the CES-D sum score. The<br />

treatment group improved by 2.1 points<br />

(6.8; range 11 to 13) between baseline<br />

and the 12-m<strong>on</strong>th visit (P 0.316; n 10).<br />

In the c<strong>on</strong>trol group, the scores decreased<br />

[mean: 7.9, (12.0; range 38 to 5; P <br />

0.027; n 9]. The comparis<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> the score<br />

changes with the Wilcox<strong>on</strong> test resulted in a<br />

Adverse events<br />

The proporti<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> patients experiencing any adverse event<br />

was similar between the DHEA and placebo groups. Single adverse<br />

events reported in the DHEA group were a fracture <str<strong>on</strong>g>of</str<strong>on</strong>g> a<br />

finger, rhinitis, upper airway infecti<strong>on</strong>, and transient pain <str<strong>on</strong>g>of</str<strong>on</strong>g> the<br />

ankle joint. One girl in the DHEA group developed a mild moustache,<br />

but no other signs <str<strong>on</strong>g>of</str<strong>on</strong>g> hirsutism. Her Ferriman score was<br />

normal (n 2). Acne was not observed in any patient. In the<br />

placebo group, headache, n<strong>on</strong>organic acral paresthesias (n 2),<br />

mood swings, and spraining <str<strong>on</strong>g>of</str<strong>on</strong>g> the ankle were reported.<br />

There was <strong>on</strong>e severe adverse event in the DHEA group and<br />

two in the placebo group: <strong>on</strong>e girl suffered from recurrent anxiety<br />

attacks that were reported after 4 m<strong>on</strong>th therapy. Similar<br />

psychological problems had occurred before the trial according<br />

to the parents. Nevertheless, because causality could not be excluded,<br />

medicati<strong>on</strong> was stopped. In the placebo group, <strong>on</strong>e girl<br />

had a relapse <str<strong>on</strong>g>of</str<strong>on</strong>g> craniopharyngioma, and another exhibited the<br />

first manifestati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> type 1 diabetes mellitus. In both cases,<br />

caused a clear progress <str<strong>on</strong>g>of</str<strong>on</strong>g> pubic hair stage by I–III stages,<br />

but increased in the placebo group. In additi<strong>on</strong>, the CES-D score<br />

DHEA group, whereas these parameters remained pathologically<br />

low in the placebo group. DHEA therapy was safe and well<br />

tolerated.<br />

Adolescence is the time <str<strong>on</strong>g>of</str<strong>on</strong>g> the <strong>on</strong>ly DHEA peak during the<br />

human life span. The normal mean serum DHEAS level at this<br />

age is at 2000 ng/ml. Therefore, DHEA deficiency is most severe<br />

when adolescent individuals are affected by adrenal insufficiency:<br />

our patients had serum DHEAS levels less than 200 ng/ml.<br />

The therapeutic substituti<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> a severe deficiency for a horm<strong>on</strong>e<br />

should cause positive effects if the horm<strong>on</strong>e is <str<strong>on</strong>g>of</str<strong>on</strong>g> any<br />

relevant physiological value for the human being. DHEA is the<br />

major source <str<strong>on</strong>g>of</str<strong>on</strong>g> androgens in females.<br />

Most <str<strong>on</strong>g>of</str<strong>on</strong>g> the girls treated had no pubarche<br />

or an immature stage <str<strong>on</strong>g>of</str<strong>on</strong>g> pubic hair development<br />

because <str<strong>on</strong>g>of</str<strong>on</strong>g> a lack <str<strong>on</strong>g>of</str<strong>on</strong>g> androgens at<br />

baseline. They experienced a clear<br />

progress <str<strong>on</strong>g>of</str<strong>on</strong>g> sexual hair growth during the<br />

trial.<br />

Interestingly, these clinical changes<br />

happened in the absence <str<strong>on</strong>g>of</str<strong>on</strong>g> a measurable<br />

normalizati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> testoster<strong>on</strong>e in the morning<br />

serum, whereas the overall androgen<br />

metabolite excreti<strong>on</strong> in the urine (C19 metabolites)<br />

reached a normal level. In additi<strong>on</strong>,<br />

morning serum levels <str<strong>on</strong>g>of</str<strong>on</strong>g> androstanediol<br />

glucur<strong>on</strong>ide normalized in the DHEA<br />

group, which has been proposed as a marker<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> peripheral androgen producti<strong>on</strong> and acti<strong>on</strong><br />

(28). These observati<strong>on</strong>s suggest that<br />

normalizati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> morning serum DHEAS<br />

and androstenedi<strong>on</strong>e was sufficient to increase<br />

locally produced testoster<strong>on</strong>e and dihydrotestoster<strong>on</strong>e<br />

to an extent that enabled<br />

sexual hair growth. The same discrepancy<br />

between normal amounts <str<strong>on</strong>g>of</str<strong>on</strong>g> androgen metabolites<br />

and low-active androgens has been<br />

observed in DHEA trials with DHEA-deficient<br />

women or healthy postmenopausal<br />

women in the past (10, 29).<br />

Beside sexual hair growth in puberty,<br />

we could c<strong>on</strong>firm that DHEA and androgens<br />

have beneficial effects <strong>on</strong> the psychological<br />

well-being. The exact biochemical<br />

path that is used by DHEA to cause such<br />

effects is still obscure, and a separati<strong>on</strong><br />

from effects caused by metabolites <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

DHEA is difficult. Such effects are <str<strong>on</strong>g>of</str<strong>on</strong>g> most<br />

importance in young patients having a<br />

chr<strong>on</strong>ic disease.<br />

This is the first c<strong>on</strong>trolled trial analyzing<br />

replacement <str<strong>on</strong>g>of</str<strong>on</strong>g> DHEA in pediatric patients.<br />

Craen et al. (16) reported <strong>on</strong> the individual<br />

treatment results in six girls who had hypopituitarism<br />

and low DHEAS serum levels using<br />

15 mg DHEAS /m 2 body surface. Central<br />

adrenal insufficiency was present in some,<br />

but not in all, <str<strong>on</strong>g>of</str<strong>on</strong>g> these patients according to<br />

the abstract published (16). Durati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> treatment was between<br />

6 and 28 m<strong>on</strong>ths. In this preliminary report, they observed<br />

an increase <str<strong>on</strong>g>of</str<strong>on</strong>g> serum DHEAS and a progress <str<strong>on</strong>g>of</str<strong>on</strong>g> pubic<br />

hair development to PH2 or more in all patients. Wit et al. (8)<br />

reported their experience with the individual treatment <str<strong>on</strong>g>of</str<strong>on</strong>g> four<br />

girls with central or peripheral adrenal insufficiency (age<br />

range 15–17.3 yr) using DHEAS at a dose <str<strong>on</strong>g>of</str<strong>on</strong>g> 25–50 mg orally.<br />

Treatment durati<strong>on</strong> was between 2 and 4 yr. They reported a<br />

positive effect <strong>on</strong> pubic hair development and normalizati<strong>on</strong><br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> DHEAS serum levels. Adverse effects <str<strong>on</strong>g>of</str<strong>on</strong>g> DHEAS were not<br />

reported in these two studies.

DHEA has been well studied in adults (9), and it is easily available.<br />

By using the lowest dose reported to being effective in adult<br />

females with adrenal insufficiency (12), DHEAS serum levels<br />

were reached that were almost identical to the healthy reference<br />

populati<strong>on</strong> at this adolescent age. In comparis<strong>on</strong>, when adult<br />

females with a mean/median age between 40 and 57 yr <str<strong>on</strong>g>of</str<strong>on</strong>g> age<br />

were treated with 25–50 mg DHEA, DHEAS serum levels<br />

reached were in median around 2000 ng/ml ( 5.4 mol/liter),<br />

which is a c<strong>on</strong>centrati<strong>on</strong> above the median for this age (10–15).<br />

In this c<strong>on</strong>text it must be noted that oral<br />

DHEA replacement <strong>on</strong>ce daily does not fully<br />

restore the diurnal rhythm <str<strong>on</strong>g>of</str<strong>on</strong>g> serum androgen<br />

levels present in healthy women. Arlt et<br />

al. (9) studied the pharmacokinetics in<br />

healthy women (mean age 23.3 yr) with<br />

transient suppressi<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> adrenal androgen<br />

secreti<strong>on</strong> because <str<strong>on</strong>g>of</str<strong>on</strong>g> dexamethas<strong>on</strong>e administrati<strong>on</strong>.<br />

Using this experimental setting,<br />

they found supraphysiological c<strong>on</strong>centrati<strong>on</strong>s<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> DHEAS during the first 12 h after<br />

oral administrati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> 50 mg DHEA, which<br />

decreased to baseline values during the<br />

sec<strong>on</strong>d half <str<strong>on</strong>g>of</str<strong>on</strong>g> the day. Similar kinetics was<br />

found for androstenedi<strong>on</strong>e and testoster<strong>on</strong>e;<br />

however, these androgen serum c<strong>on</strong>centrati<strong>on</strong>s<br />

did not reach baseline at any<br />

time. Therefore, the normalizati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

morning serum levels in our DHEA group<br />

observed might not have been associated<br />

with normal serum levels during the whole<br />

day.<br />

In this study, adolescents and young<br />

adults with female gender <strong>on</strong>ly were treated.<br />

Therefore, results cannot be generalized to<br />

both genders. In male adolescents, androgens<br />

produced in testes may substitute for<br />

the missing adrenal androgens. Whether<br />

DHEA deficiency causes a relevant estrogen<br />

deficiency in adult males is still a matter <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

debate. In pediatrics, data are missing to<br />

support such a hypothesis. We restricted the<br />

inclusi<strong>on</strong> to those children with adrenal insufficiency<br />

caused by ACTH deficiency.<br />

Therefore, the rare cases <str<strong>on</strong>g>of</str<strong>on</strong>g> primary adrenal<br />

insufficiency like in Addis<strong>on</strong>’s disease, c<strong>on</strong>genital<br />

adrenal hypoplasia, and familial glucocorticoid<br />

deficiency were not investigated.<br />

To date, there are no rati<strong>on</strong>al arguments that<br />

this specific group needs a different regiment<br />

to treat for DHEA deficiency. The group <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

patients studied was small and the time <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

therapy limited to 12 m<strong>on</strong>ths. Therefore,<br />

data <strong>on</strong> any possibly occurring rare or late<br />

adverse effect could not be detected by this<br />

study. However, based <strong>on</strong> the data available from studies in<br />

adults, there is no relevant c<strong>on</strong>cern regarding safety <str<strong>on</strong>g>of</str<strong>on</strong>g> the drug<br />

DHEA at an oral dose <str<strong>on</strong>g>of</str<strong>on</strong>g> 25–50 mg daily.<br />

Here, we have shown for the first time that DHEA replacement<br />

in female adolescents and young women with central adrenal<br />

insufficiency causes a substantial change in sexual hair<br />

growth indicating efficacy <str<strong>on</strong>g>of</str<strong>on</strong>g> this drug. For the patient with the<br />

burden <str<strong>on</strong>g>of</str<strong>on</strong>g> a complex horm<strong>on</strong>e deficiency disorder, normalizati<strong>on</strong><br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> the physical appearance is very important. In additi<strong>on</strong>, we<br />

observed a clear improvement <str<strong>on</strong>g>of</str<strong>on</strong>g> psychological distress and depressi<strong>on</strong><br />

scores that may be beneficial in the situati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> adolescence,<br />

which is very vulnerable for any psychological crisis. In the

future we need internati<strong>on</strong>al l<strong>on</strong>g-term replacement studies with<br />

larger numbers <str<strong>on</strong>g>of</str<strong>on</strong>g> affected girls to evaluate changes in quality <str<strong>on</strong>g>of</str<strong>on</strong>g><br />
