Outcome Measures

Primary Outcomes (1)

  • Change in Serum DHEAS Levels

    Change in DHEAS level was constructed per subject as the 1-year measurement minus the baseline measurement. Only descriptive statistics are provided, statistical tests were not conducted given the extremely small sample size per group.

Eligibility Criteria

Age4 Years - 10 Years
Sexfemale
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Girls aged 4-10 with pubic hair prior to 8 years of age
  • Elevated DHEAS level above age normal levels
  • Informed consent from parents and assent from the girl

You may not qualify if:

  • Diagnosis of incomplete precocious puberty, peripheral precocious puberty, or evidence of any abnormal pituitary, hypothalamic, adrenal, thyroid, and gonadal function other than premature secretion of adrenal androgens.
  • Chronic illness requiring treatment that may interfere with growth and development, i.e. chronic steroid use, renal failure, etc.
  • Uncorrected thyroid disease (defined as TSH \< 0.2 mIU/ML or \> 5.5 mIU/mL). A normal level within the last year is adequate for entry.
  • Type I or Type II diabetes (defined as a fasting serum glucose \> 125mg/dL on two occasions 83), or patients receiving anti-diabetic medications such as insulin, thiazolidinediones, acarbose, or sulfonylureas; patients currently receiving metformin XR for a diagnosis of Type I or Type II diabetes or for PCOS are also specifically excluded.
  • Liver disease defined as AST or ALT \> 2 times normal or total bilirubin \> 2.5 mg/dL.
  • Renal disease defined as BUN \> 30 mg/dL or serum creatinine \> 1.4 mg/dL.
  • Significant anemia (Hemoglobin \< 10 mg/dL).
  • History of deep venous thrombosis, pulmonary embolus, or cerebrovascular accident.
  • Known heart disease (New York Heart Association Class II or higher).
  • Enrolled simultaneously into other investigative studies that require medications, proscribe the study medications, or otherwise prevent compliance with the protocol. Patients who anticipate taking longer than a one month break during the protocol should not be enrolled.
  • Concomitant use other medications known to affect reproductive function or metabolism. These medications include growth hormone, IGF-1, medroxyprogesterone acetate, oral contraceptives, GnRH agonists and antagonists, anti-androgens, gonadotropins, anti-obesity drugs, somatostatin, diazoxide, ACE inhibitors, and calcium channel blockers. The washout period on all these medications will be three months.
  • Suspected adrenal or ovarian tumor secreting androgens or other ectopic steroid secreting tumor.
  • Suspected Cushing's syndrome.
  • Lactose intolerance (the placebo filler is lactose).
  • Known hypersensitivity to study medication, including ACTH and GnRH, or their excipients.
  • +3 more criteria
