Obesity, inflammation, and insulin resistance.

Objective: The aim was to formulate practice guidelines for the diagnosis and treatment of hyperprolactinemia. Participants: The Task Force consisted of Endocrine Society-appointed experts, a methodologist, and a medical writer. Evidence: This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system to describe both the strength of recommendations and the quality of evidence. Consensus Process: One group meeting, several conference calls, and e-mail communications enabled consensus. Committees and members of The Endocrine Society, The European Society of Endocrinology, and The Pituitary Society reviewed and commented on preliminary drafts of these guidelines. Conclusions: Practice guidelines are presented for diagnosis and treatment of patients with elevated prolactin levels. These include evidence-based approaches to assessing the cause of hyperprolactinemia, treating drug-induced hyperprolactinemia, and managing prolactinomas in nonpregnant and pregnant subjects. Indications and side effects of therapeutic agents for treating prolactinomas are also presented. (J Clin Endocrinol Metab 96: 273–288, 2011)

Diagnosis and treatment of hyperprolactinemia: an Endocrine Society clinical practice guideline

Objective To update the "Endocrine Treatment of Transsexual Persons: An Endocrine Society Clinical Practice Guideline," published by the Endocrine Society in 2009. Participants The participants include an Endocrine Society-appointed task force of nine experts, a methodologist, and a medical writer. Evidence This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation approach to describe the strength of recommendations and the quality of evidence. The task force commissioned two systematic reviews and used the best available evidence from other published systematic reviews and individual studies. Consensus process Group meetings, conference calls, and e-mail communications enabled consensus. Endocrine Society committees, members and cosponsoring organizations reviewed and commented on preliminary drafts of the guidelines. Conclusion Gender affirmation is multidisciplinary treatment in which endocrinologists play an important role. Gender-dysphoric/gender-incongruent persons seek and/or are referred to endocrinologists to develop the physical characteristics of the affirmed gender. They require a safe and effective hormone regimen that will (1) suppress endogenous sex hormone secretion determined by the person's genetic/gonadal sex and (2) maintain sex hormone levels within the normal range for the person's affirmed gender. Hormone treatment is not recommended for prepubertal gender-dysphoric/gender-incongruent persons. Those clinicians who recommend gender-affirming endocrine treatments-appropriately trained diagnosing clinicians (required), a mental health provider for adolescents (required) and mental health professional for adults (recommended)-should be knowledgeable about the diagnostic criteria and criteria for gender-affirming treatment, have sufficient training and experience in assessing psychopathology, and be willing to participate in the ongoing care throughout the endocrine transition. We recommend treating gender-dysphoric/gender-incongruent adolescents who have entered puberty at Tanner Stage G2/B2 by suppression with gonadotropin-releasing hormone agonists. Clinicians may add gender-affirming hormones after a multidisciplinary team has confirmed the persistence of gender dysphoria/gender incongruence and sufficient mental capacity to give informed consent to this partially irreversible treatment. Most adolescents have this capacity by age 16 years old. We recognize that there may be compelling reasons to initiate sex hormone treatment prior to age 16 years, although there is minimal published experience treating prior to 13.5 to 14 years of age. For the care of peripubertal youths and older adolescents, we recommend that an expert multidisciplinary team comprised of medical professionals and mental health professionals manage this treatment. The treating physician must confirm the criteria for treatment used by the referring mental health practitioner and collaborate with them in decisions about gender-affirming surgery in older adolescents. For adult gender-dysphoric/gender-incongruent persons, the treating clinicians (collectively) should have expertise in transgender-specific diagnostic criteria, mental health, primary care, hormone treatment, and surgery, as needed by the patient. We suggest maintaining physiologic levels of gender-appropriate hormones and monitoring for known risks and complications. When high doses of sex steroids are required to suppress endogenous sex steroids and/or in advanced age, clinicians may consider surgically removing natal gonads along with reducing sex steroid treatment. Clinicians should monitor both transgender males (female to male) and transgender females (male to female) for reproductive organ cancer risk when surgical removal is incomplete. Additionally, clinicians should persistently monitor adverse effects of sex steroids. For gender-affirming surgeries in adults, the treating physician must collaborate with and confirm the criteria for treatment used by the referring physician. Clinicians should avoid harming individuals (via hormone treatment) who have conditions other than gender dysphoria/gender incongruence and who may not benefit from the physical changes associated with this treatment.

Endocrine Treatment of Gender-Dysphoric/Gender-Incongruent Persons: An Endocrine Society Clinical Practice Guideline

Objective: The aim was to provide guidelines for evaluation, treatment, and genetic testing for multiple endocrine neoplasia type 1 (MEN1). Participants: The group, which comprised 10 experts, including physicians, surgeons, and geneticists from international centers, received no corporate funding or remuneration. Process: Guidelines were developed by reviews of peer-reviewed publications; a draft was prepared, reviewed, and rigorously revised at several stages; and agreed-upon revisions were incorporated. Conclusions: MEN1 is an autosomal dominant disorder that is due to mutations in the tumor suppressor gene MEN1, which encodes a 610-amino acid protein, menin. Thus, the finding of MEN1 in a patient has important implications for family members because first-degree relatives have a 50% risk of developing the disease and can often be identified by MEN1 mutational analysis. MEN1 is characterized by the occurrence of parathyroid, pancreatic islet, and anterior pituitary tumors. Some patients may also develo...

Clinical practice guidelines for multiple endocrine neoplasia type 1 (MEN1)

Objective: The aim was to formulate practice guidelines for endocrine treatment oftranssexual persons. Evidence: This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system to describe the strength of recommendations and the quality of evidence, which was low or very low. Consensus Process: Committees and members of The Endocrine Society, European Society of Endocrinology, European Society for Paediatric Endocrinology, Lawson Wilkins Pediatric Endocrine Society, and World Professional Association for Transgender Health commented on preliminary drafts of these guidelines. Conclusions: Transsexual persons seeking to develop the physical characteristics of the desired gender require a safe, effective hormone regimen that will 1) suppress endogenous hormone secretion determined by the person’s genetic/biologic sex and 2) maintain sex hormone levels within the normal range for the person’s desired gender.

Endocrine Treatment of Transsexual Persons: An Endocrine Society Clinical Practice Guideline

Summary
objective Acromegaly has long been associated with increased mortality but few long-term follow-up data are available in patients treated for this disease. We therefore studied a group of 103 patients who underwent transsphenoidal adenomectomy for acromegaly between 1970 and 1999 and were followed for one to 30 years.

design and patients A retrospective chart review was performed on 103 patients living in the province of Quebec, Canada. Mortality data were obtained by hospital charts, contact with the patient's family or death certificates. Stringent biochemical criteria were used to define remission (random GH < 2·5 µg/l, or GH nadir after an oral glucose load is < 1 µg/l and IGF-I within the normal range) and patient survival in the group in remission and the group with persistent disease were compared to survival of the population of Quebec, Canada, using the probabilities of the Poisson distribution.

results There were four deaths in the perioperative period, one of which was directly related to surgery. Initial remission was obtained in 82% of microadenomas, 60% of macroadenomas and 24% of invasive adenomas. The long-term (≥ 10 years) remission rate for surgery alone was 52%. A second transsphenoidal surgery, radiation therapy and/or octreotide were used in a subset of patients with persistent disease. Long-term remission was obtained in 63% of patients. Five (mean age, 64 years) of the 57 patients in remission died; this rate did not differ significantly from the mortality rate expected in the general population (P = 0·18). Thirteen (mean age, 59·8 years) of the 34 patients with persistent disease died; this rate was significantly higher than that expected in the general population (P = 0·008).

conclusions Our observations confirm that uncontrolled acromegaly increases mortality compared to the general population and that mortality rates similar to the general population are restored once remission is induced.

Long-term outcome and mortality after transsphenoidal adenomectomy for acromegaly.

To assess the long-term prognosis for women with prolactinoma after selective transsphenoidal adenomectomy, we followed 44 patients for 62±15 years Group 1 (28 patients) had microprolactinomas, and Group 2 (16 patients) had macroprolactinomas After surgery, normal plasma prolactin levels, resumption of menses, and cessation of galactorrhea were observed in 24 Group 1 patients (85 per cent) and 5 Group 2 patients (31 per cent) Hyperprolactinemia recurred in 12 of the 24 Group 1 patients and in 4 of the 5 Group 2 patients after 4±13 and 25±16 years of remission, respectively There was no radiologic evidence of tumor recurrence in any patient, and no relation was found between the occurrence of pregnancy after surgery and the recurrence of hyperprolactinemia Clinical and biologic features before surgery could not predict the long-term outcome However, the immediate postoperative level of plasma prolactin was significantly lower in patients in whom normal prolactinemia (64±11 ng per mill

Recurrence of hyperprolactinemia after selective transsphenoidal adenomectomy in women with prolactinoma.

From 1962 to 1987, 126 patients underwent trans-sphenoidal surgery for primary treatment of pituitary adenomas unassociated with clinical or biochemical evidence of hormonal overproduction. There were 73 male and 53 female patients (mean age, 50 +/- 12 years). Before surgery, 56% of the patients (70 of 124) had headaches, 74% (94 of 126) had deterioration of vision, and 12% (15 of 126) had ophthalmoplegia. Endocrine evaluation revealed the presence of hypogonadism in 75% (87 of 115), adrenal insufficiency in 36% (46 of 126), and hypothyroidism in 18% (21 of 122). Plasma prolactin was increased in 65% (56 of 86) with a mean level of 39 +/- 14 micrograms/l (normal, 3 to 20 micrograms/l). Radiologic enlargement of the sella turcica was documented in all cases: 67% (84 of 126) had enclosed and 33% (42 of 126) had invasive adenomas. After surgery, vision was normalized or improved in 75% (71 of 94) of the patients. Thyroid, adrenal, and gonadal functions were improved in 14% (three of 22), 41% (19 of 46), 11% (ten of 87), were unchanged in 82% (100 of 122), 77% (97 of 126), 89% (102 of 115), and worsened in 15% (19 of 22), 8% (ten of 126), 3% (102 of 115), respectively. Permanent diabetes insipidus occurred in 5% (seven of 126). Two patients died during the immediate postoperative period. The recurrence rate in patients with a mean follow-up of 6.4 +/- 4.2 years was 21% (15 of 71). These data indicate that trans-sphenoidal microsurgery is an effective and safe initial treatment for patients with nonsecreting pituitary adenoma and may reverse hypopituitarism.

The clinical and endocrine outcome to trans-sphenoidal microsurgery of nonsecreting pituitary adenomas

PROLACTIN IS A PITUITARY HORMONE that plays a pivotal role in a variety of reproductive functions. Hyperprolactinemia is a common condition that can result from a number of causes, including medication use and hypothyroidism as well as pituitary disorders. Depending on the cause and consequences of the hyperprolactinemia, selected patients require treatment. The underlying cause, sex, age and reproductive status must be considered. We describe the diagnostic approach and management of hyperprolactinemia in various clinical settings, with emphasis on newer diagnostic strategies and the role of various therapeutic options, including treatment with selective dopamine agonists.

Diagnosis and management of hyperprolactinemia

OBJECTIVE To evaluate the effect of gliclazide administration to NIDDM patients on 1) monocyte adhesion to cultured endothelial cells, 2) plasma cytokine and lipid peroxide levels, and 3) monocyte cytokine production. RESEARCH DESIGN AND METHODS Poorly controlled glyburide-treated diabetic patients ( n = 8) and healthy control subjects ( n = 8) were recruited. At the beginning of the study, glyburide was replaced by an equivalent hypoglycemic dose of gliclazide. Serum and monocytes were isolated from blood obtained from control and diabetic subjects before and after 3 months of treatment with gliclazide. RESULTS Plasma lipid peroxide levels and monocyte adhesion to endothelial cells are enhanced in NIDDM patients, and gliclazide administration totally reverses these abnormalities. Before gliclazide treatment, serum levels of cytokines did not differ in the control and the diabetic groups, with the exception of an enhancement of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL)-6 in NIDDM subjects. Basal and lipopolysaccharide (LPS)-stimulated monocyte production of interleukin-1β, IL-6, and IL-8 did not differ between the two groups. Furthermore, basal monocyte production of TNF-α was similar in the control and the diabetic groups, whereas a marked increase in the LPS-stimulated monocyte production of TNF-α was observed in the NIDDM group. Gliclazide treatment lowered LPS-stimulated TNF-α production by diabetic monocytes to levels similar to those observed in control subjects. CONCLUSIONS Gliclazide administration to NIDDM patients inhibits the increased adhesiveness of diabetic monocytes to endothelial cells and reduces the production of TNF-α by these cells. These results suggest that treatment of NIDDM subjects with gliclazide may be beneficial in the prevention of atherosclerosis associated with NIDDM.
