Evaluation of hirsutism

Ultrasound is not recommended in adolescents, as there are no definitive criteria to define polycystic ovary morphology in this population.[13]Teede HJ, Tay CT, Laven J, et al. Recommendations from the 2023 international evidence-based guideline for the assessment and management of polycystic ovary syndrome.

The best method for evaluation of total testosterone is liquid chromatography with tandem mass spectrometry.[13]Teede HJ, Tay CT, Laven J, et al.

In women with obesity, sex hormone-binding globulin levels are low, resulting in elevated free testosterone and often normal total testosterone. Androgen level tests should be performed in the follicular phase (in cycling women), in the morning, and at least 3 months after cessation of any hormonal therapies other than cyclic progestin.

The best method for evaluation of total testosterone is liquid chromatography with tandem mass spectrometry (LC-MS/MS). This has higher specificity and less interference with other androgens, such as androstenedione and dehydroepiandrosterone sulfate (DHEAS).[16]Barth JH, Field HP, Yasmin E, et al.

Hum.Genet. 2019 Nov 20;20(25). https://jmhg.springeropen.com/articles/10.1186/s43042-019-0031-4 If total testosterone is normal, free testosterone can be assessed by measurement of serum total testosterone and sex hormone binding protein, followed by calculation of the free androgen index.[25]Vermeulen A, Verdonck L, Kaufman JM.

Endocrine Society guidelines recommend measuring early morning serum total and free testosterone in premenopausal women who have normal total testosterone, but who have moderate to severe sexual hair growth or mild sexual hair growth in the presence of symptoms or signs suggesting a hyperandrogenic endocrine disorder, such as menstrual disturbance.[1]Martin KA, Anderson RR, Chang RJ, et al.

Prolactin levels increase proportionally to the size of the tumor.[26]Schlechte JA. Clinical practice. Prolactinoma. N Engl J Med. 2003 Nov 20;349(21):2035-41. http://www.ncbi.nlm.nih.gov/pubmed/14627789?tool=bestpractice.com

CT may be an alternative, but MRI is more sensitive for small lesions.[26]Schlechte JA. Clinical practice. Prolactinoma. N Engl J Med. 2003 Nov 20;349(21):2035-41. http://www.ncbi.nlm.nih.gov/pubmed/14627789?tool=bestpractice.com

Should be measured in the morning, during follicular phase; levels may be higher in the afternoon. For women with amenorrhea/infrequent menses it can be done on a random day. In women considered to have a high risk of nonclassic congenital adrenal hyperplasia this screening test is recommended even if serum total and free testosterone are normal.[1]Martin KA, Anderson RR, Chang RJ, et al. Evaluation and treatment of hirsutism in premenopausal women: an Endocrine Society clinical practice guideline.

Diagnosis should be confirmed by ACTH stimulation test.[28]White PC, Speiser PW. Congenital adrenal hyperplasia due to 21-hydroxylase deficiency. Endocr Rev. 2000 Jun;21(3):245-91. https://www.doi.org/10.1210/edrv.21.3.0398 http://www.ncbi.nlm.nih.gov/pubmed/10857554?tool=bestpractice.com

Cosyntropin, a synthetic form of ACTH, is injected (0.25 micrograms intravenously/intramuscularly), and measurements of 17-hydroxyprogesterone are done before administration and after 30 and 60 minutes. The diagnosis of nonclassic congenital adrenal hyperplasia is confirmed when levels are >1500 nanograms/dL.[20]Azziz R, Dewailly D, Owerbach D. Clinical review 56: nonclassic adrenal hyperplasia: current concepts. J Clin Endocrinol Metab. 1994 Apr;78(4):810-5. http://www.ncbi.nlm.nih.gov/pubmed/8157702?tool=bestpractice.com

An intramuscular depot formulation of cosyntropin is used in cases of suspected adrenocortical insufficiency where the original tests yield inconclusive results.

One of the first-line tests to consider in any patient with suspected Cushing syndrome.[29]Fleseriu M, Auchus R, Bancos I, et al.

Obtaining multiple (at least two) samples may increase sensitivity, and initial testing should be performed with sampling on two separate nights.[30]Nieman LK, Biller BM, Findling JW, et al.

Should not be used in patients taking drugs affecting dexamethasone metabolism (e.g., phenytoin, carbamazepine, rifampin, cimetidine).

Dexamethasone levels are measured simultaneously with cortisol to ensure that appropriate levels are achieved. This may help in severely obese patients whose dexamethasone levels may be suboptimal.

Positive results should be confirmed with late-night salivary cortisol or 24-hour urinary free cortisol.

Transvaginal pelvic ultrasound is the preferred imaging modality to evaluate a clinically suspected ovarian mass, providing both qualitative and quantitative information valuable in management. Combined transvaginal and transabdominal ultrasound may be useful for evaluating larger masses.

Ultrasound with Doppler imaging can characterize the mass (e.g., cystic, solid, complex), and in most cases can triage the mass into benign or malignant categories.

Serum CA-125 levels are elevated in >80% of women with advanced-stage disease. However, this biomarker is not diagnostic because CA-125 levels can be elevated as a result of nonmalignant conditions (e.g., endometriosis, uterine fibroids, pregnancy, pelvic inflammatory disease, appendicitis, and ovarian cysts) and other malignant conditions (e.g., pancreatic, breast, lung, gastric, and colon cancers). Furthermore, normal CA-125 levels are observed in approximately 50% of patients with early-stage ovarian cancer.[35]Tuxen MK, Sölétormos G, Dombernowsky P. Tumor markers in the management of patients with ovarian cancer. Cancer Treat Rev. 1995 May;21(3):215-45.
