[PMID: 32734551 DOI: 10.1007/s12020-020-02430-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Accepted: 07/18/2020] [Indexed: 10/23/2022]
Abstract
INTRODUCTION Few data are available on the risks of first-generation somatostatin receptor ligands (SRLs) during pregnancy in women treated for acromegaly. Current recommendations suggest the withdrawal of treatment at diagnosis of pregnancy. The aims of this literature review were to evaluate the teratogenic effects and the potential impact of SRLs on maternal and fetal outcomes by comparing acromegalic patients treated or not during pregnancy. PATIENTS AND METHODS This study concerns 141 pregnancies in 127 women with acromegaly: 67 pregnancies in 62 women treated with SRLs during pregnancy and 74 pregnancies in 65 women not medically treated during pregnancy. A second analysis was then realized comparing women treated during 1st trimester only (36 pregnancies) and women treated longer (20 pregnancies). RESULTS One malformation (ureteral stenosis) was reported in a newborn of a woman treated with SRL during pregnancy. No difference was found concerning maternal outcomes (gestational diabetes, hypertension, headaches, and delivery mode) and fetal outcomes (birth term, height, and weight). These results were also confirmed for the second analysis. CONCLUSIONS This review of the literature did report one malformation without being able to prove a specific link with the first-generation SRL treatment. No significant impact on maternal and fetal outcomes is related to first-generation SRL treatment in women with acromegaly. The number of pregnancies is still low and more data are necessary to conclude on the total safety of this treatment during gestation. In the meantime, based on the nonthreatening data from this review of literature, SRL treatment can be continued and/or reintroduced during pregnancy if necessary (mainly for persistent headaches) in women with acromegaly.

Abstract
Pituitary adenomas are common. The impact of pituitary tumors on fertility are mainly caused by oversecretion and/or undersecretion of pituitary hormones or compression of pituitary stalk and normal pituitary tissue by the tumor. Diagnosing and managing pituitary tumors during pregnancy involve many challenges, including the effect of hormone excess or deficiency on pregnancy outcome, changes in the pituitary or pituitary-related hormones, changes in tumor size, and the impact of various treatments of pituitary tumors on maternal and fetal outcomes. This article discusses the diagnosis and treatment of patients with prolactinomas, acromegaly, Cushing disease, and other pituitary tumors during pregnancy.

Abstract
INTRODUCTION As pregnancy is rare in women with acromegaly, only case reports and few series have been published. AREAS COVERED All case reports and publications dealing with pregnancy in patients with acromegaly were collated. Information concerning the effects of acromegaly on pregnancy outcomes, the impact of pregnancy on GH/IGF-I measurements, acromegaly comorbidity and pituitary adenoma size, the effects of treatment of acromegaly on fetus outcomes were retrieved and analyzed. EXPERT COMMENTARY Based on the small number of reported cases, pregnancy is generally uneventful, except for a potential increased incidence of gestational hypertension and diabetes mellitus. Medical therapy of acromegaly (dopamine agonists, somatostatin analogs, growth hormone-receptor antagonists) is generally interrupted before or at diagnosis of pregnancy. In very rare patients with a pituitary adenoma, particularly a macroadenoma that has not been surgically treated before pregnancy, or if a surgical remnant persists, or when acromegaly is revealed during pregnancy, tumor volume may increase and cause symptoms through a mass effect. Close monitoring of clinical manifestations and imaging are necessary during pregnancy in these cases. In the rare cases of symptomatic tumor enlargement during pregnancy, medical treatment with dopamine agonists or eventually somatostatin analogs may be attempted before resorting to transsphenoidal surgery.

Abstract
OBJECTIVE To assess the outcome of pregnancies in a large cohort of women with acromegaly. DESIGN AND METHODS This is a retrospective analysis of 31 pregnancies in 20 patients with acromegaly. RESULTS Twenty-seven pregnancies resulted in healthy offspring, and 4 resulted in abortion. Three patients underwent transsphenoidal surgery during pregnancy. IGF-1 levels remained elevated during pregnancy in 4 pregnancies and normalized in 23 cases. Fifteen cases were followed during pregnancy without any medical or surgical treatment, and 13 of these exhibited normal IGF-1 levels. Before or during pregnancy, somatostatin receptor ligands usage was not associated with higher risk for adverse outcomes. Arterial hypertension worsening (45%) and impairment of glucose levels (32%) were the most common complications during pregnancies. There were no maternal or neonatal deaths. One woman delivered twins. Two cases of congenital malformations and one with foetal macrosomia were observed. Caesarean delivery was performed in sixteen cases. CONCLUSION Our study confirms the impact of gestation on IGF-1 levels. However, it also indicates that acromegaly still holds an increased risk for worsening of comorbidities, especially in uncontrolled patients.

Abstract
Although fertility is frequently impaired in women with acromegaly, pregnancy is apparently becoming more common due to improvement in acromegaly treatment as well as in fertility therapy. As a result, several studies on pregnancy in patients with acromegaly have been published in recent years adding new and relevant information to the preexisting literature. Also, new GH assays with selective specificities and the knowledge of the expression of the various GH genes have allowed a better understanding of somatotrophic axis function during pregnancy. In this review, we show that pregnancy in women with acromegaly is generally safe, usually with tumoral and hormonal stability. Although the paucity of data limits evidence-based recommendations for preconception counseling and pregnancy surveillance, controlling tumor size and hormonal activity before pregnancy is highly recommended to ensure better outcomes, and surgical control should be attempted when feasible. Treatment interruption at pregnancy confirmation has also proven to be safe, as drugs are not formally allowed to be used during pregnancy. Drug exposure (somatostatin analogs) during early or whole pregnancy might increase the chance of a lower birth weight. Aggressive disease is uncommon and may urge individual decisions such as surgery or drug treatment during pregnancy or lactation.

Abstract
BACKGROUND AND AIMS Approximately 174 pregnancies in acromegaly have been reported. Our objectives were to identify the key challenges of preconception counselling in this population. METHODS Case series of three acromegalic women with desire for pregnancy. Issues were identified from chart review and discussion with attending physicians. Literature review of acromegaly and pregnancy was conducted. RESULTS Important issues identified included: impact of acromegaly on fertility, management of acromegaly in the peripartum period, screening for associated conditions, risk of progression of acromegaly/tumour growth during pregnancy, impact of acromegaly on pregnancy outcomes, surveillance during pregnancy, method of delivery and impact on neonatal outcomes and breastfeeding. CONCLUSIONS Pregnancy can be safely achieved in patients with acromegaly. There is little evidence to guide recommendations around conception and pregnancy surveillance. Patients can be reassured that in most situations, pregnancy proceeds without complication and that medical treatment can be used during pregnancy if necessary.

Abstract
INTRODUCTION A decrease of insulin-like growth factor-I levels (IGF-I) has been reported during the first trimester of pregnancy in women with acromegaly before the secretion of placental growth hormone (GH) progressively increases IGF-1 concentration. STUDY DESIGN To evaluate variations of concentrations of IGF-1, insulin-like growth factor (IGF)-binding protein-3 (IGF-BP3) and GH during the first trimester of pregnancy in women with normal somatotroph function. PATIENTS AND METHODS Sixteen women (median age 31 years) with as who were followed for benign thyroid disorders (n = 15) or prolactin-secreting microadenoma (n = 1) were evaluated before and in the first trimester of pregnancy. Serum concentrations of GH, IGF-1, IGF-BP3, TSH and estradiol (E2) were measured before and in the first trimester (5.4 ± 2.2 weeks of gestation). RESULTS Before pregnancy, somatotroph and thyroid functions (median TSH 1.2 mU/L) were normal in all women. At the first trimester IGF-1 levels decreased significantly (before = 210 ng/mL, first trimester = 145 ng/mL, p < 0.001) with no significant change in GH (before = 1.5 ng/mL, first trimester = 0.84 ng/mL) or IGF-BP3 levels (before = 2.3 ng/mL, first trimester = 2.2 ng/mL), while estradiol levels increased significantly (before = 46.5 pg/100 mL, first trimester = 448.5 pg/100 mL, p < 0.001). CONCLUSION In women with normal somatotroph function, IGF-1 levels decrease in the first trimester of pregnancy without changes in GH or IGF-BP3 levels. These results confirm liver resistance to GH as a consequence of the physiological increase of estrogens during the first trimester.

Abstract
The improved management of pituitary adenomas has led to an increasing number of pregnancies in patients harboring pituitary adenomas. Therefore, adequate management of pregnant women with pituitary adenomas is of growing importance. Because pregnancy produces several physiologic changes to the endocrine system, especially to the pituitary gland, endocrinologists must be knowledgeable and skilled to effectively manage pregnant women with pituitary adenomas and to guarantee the wellbeing of the fetus.

Abstract
CONTEXT AND OBJECTIVE The interaction between pregnancy and acromegaly has been studied only retrospectively. We used prospective data to assess those interactions. DESIGN Prospective, interventional, multicentric study. PATIENTS TEN PREGNANCIES IN EIGHT ACROMEGALIC PATIENTS WERE INCLUDED ACCORDING TO THE FOLLOWING CRITERIA: previous diagnosis of acromegaly; and active acromegaly before pregnancy. Sellar magnetic resonance image (MRI), GH, and IGF1 measurements were carried out before pregnancy. The exclusion criterion was radiotherapy. INTERVENTION Withdrawal of pharmacological treatment (octreotide and/or cabergoline and/or pegvisomant) following pregnancy diagnosis. MAIN OUTCOME MEASURES Clinical/biochemical evaluations throughout pregnancy/puerperium and sellar MRI after delivery; and GH and IGF1 measurements before pregnancy. GH was measured by an interference-free IFMA assay during pregnancy and IGF1 by measured by Immulite 2000 assay in patients and 64 control pregnancies. RESULTS No tumor growth was observed. Nine deliveries were at term and one at 35 weeks (preeclampsia). All newborns were healthy. Mean IGF1 levels before and during pregnancy were similar, but increased significantly during puerperium. As IGF1 in controls increased after midgestation, the prevalence of controlled IGF1 rose significantly from 2/10 (<20 weeks) to 9/10 (>30 weeks). Diabetes mellitus and hypertension/preeclampsia developed in one patient in each group; both complications were nonsignificantly (P=0.06) associated with IGF1 >1.3 ULN before pregnancy. CONCLUSIONS Acromegaly control usually improved and tumor growth was not stimulated during pregnancy in spite of withdrawal of drug treatment. Drug treatment can be discontinued in most patients. Uncontrolled disease before pregnancy may pose a higher risk for diabetes and hypertension.

Abstract
INTRODUCTION Pregnancies in acromegalic women are rare. Data from the literature indicate absence of congenital malformation in newborns, an increase of pituitary adenoma volume rarely clinically symptomatic, an increased risk of gestational diabetes and gravid hypertension in women with non-controlled GH/IGF-1 hypersecretion before gestation. The changes of somatotroph function are rarely described. AIM OF THE STUDY Report of six new pregnancies in five women with acromegaly. PATIENTS AND METHODS Before pregnancy three women had incomplete surgical resection of GH-secreting pituitary adenoma, all were treated with somatostatin analogues, and the medical treatment was withdrawal at the diagnosis of gestation. We studied clinical (blood pressure, headaches, visual field), biological (blood glucose concentration) signs, GH and IGF-1 levels were measured during each trimester of pregnancy as well as in post-partum and were compared with pregestational values, MRI of the pituitary performed during the second trimester and in the post-partum were compared with MRI examen before pregnancy. RESULTS All those pregnancies were normal without gestational diabetes, gravid hypertension and pituitary tumor syndrome. Clinical signs of acromegaly improved in 50 % of the patients, and IGF-1 decreased (22 %) in comparison of pregestational value without significant change in GH levels. No newborn had congenital malformation. CONCLUSION Pregnancies in those women with acromegaly are uneventful without obstetrical or foetal complication, but a maternal follow-up is necessary in order to diagnose gravid hypertension and gestational diabetes. On the other hand, a clinical monitoring of pituitary tumor syndrome is necessary in women with non-operated GH-secreting macroadenoma before pregnancy. During the first trimester of gestation, an improvement of acromegalic signs can be due to a decrease of IGF-1 levels related to hepatic GH-resistance state secondary to physiological secretion of estrogens during gestation.

Abstract
Estrogens have been used in patients with acromegaly since the 1930-1940s, suppressing plasma IGF-1 levels and improving clinical signs and symptoms of acromegaly. Estrogens antagonize GH function at the post-receptor level, inhibiting GH signaling, thus decreasing GH-induced hepatic IGF-1 synthesis. We report our experience with four female patients with active acromegaly, naïve to medical treatment or inadequately controlled by somatostatin receptor ligands (SRLs) or the GH-receptor antagonist. Adding estrogen treatment (contraceptive pills or transdermal estrogen patches) to their ongoing medical treatment, suppressed IGF-1 significantly in all patients, achieving hormonal remission in three of them. We review the available data on the use of estrogens and selective estrogen receptor modulators in acromegaly, and their mechanisms of action. Estrogens could be an alternative, inexpensive adjuvant treatment for females with active acromegaly, who are only partially responding to SRLs or to the GH-receptor antagonist.

Abstract
To review the literature regarding the diagnosis and management of acromegaly during pregnancy. A systematic literature search was performed using MEDLINE including hand-searching reference lists from original articles. The diagnosis of acromegaly during pregnancy is made difficult due to the physiologic changes in pituitary GH secretion and IGF-1 production resulting from placental GH secretion and the inability of commercial assays to discriminate between pituitary and placental GH. Most patients with acromegaly during pregnancy do not have an increase in tumor size, metabolic complications are uncommon, and neonatal outcome is largely unaffected. IGF-1 levels tend to be stable in such patients possibly due to the high estrogen levels causing GH resistance. Dopamine agonists, somatostatin analogues, and a GH receptor antagonist have been reported to be safe during pregnancy. Patients with visual field defects should be considered for surgery, but in most cases this can be safely postponed until after delivery. Overall, pregnancy in acromegaly is uneventful and newborns unaffected. Dopamine agonists and somatostatin analogues have not been associated with major adverse effects to the fetus; however, more data are needed to validate their safety.

Abstract
BACKGROUND Acromegaly results from increased growth hormone and its target insulin-like growth factor-1, most commonly due to a pituitary tumour. As it is frequently accompanied by infertility, little is known about the course of this disease in pregnancy. OBJECTIVE We describe 13 new pregnancies in acromegalic women and compare their outcomes in a systematic review of the literature. METHODS We collected clinical, biochemical, imaging, and outcomes data during and following pregnancy and performed a systematic review for a total of 47 pregnancies. An extended analysis of 106 pregnancies was also performed. RESULTS In 13 newly described cases, pregnancy was un-complicated without need for additional surgical intervention. In these pregnancies, adjunctive medical therapy was required in three patients. This was in the form of somatostatin analogs (SA) (3/13) as well as pegvisomant in 1/13 to control symptomatic and biochemical progression. One 37-year-old female succeeded in having two separate pregnancies 2 years apart both without need for any form of medical therapy. Review of an additional 34 published reports allowed for an analysis of outcomes in 47 pregnancies. Adjunctive medical therapy during pregnancy was required in 15 of these cases where 12 received SA and an additional three received dopamine agonists. None of these patients developed endocrine or neurologic complications during pregnancy. In an extended analysis of 106 pregnancies, treatment during pregnancy appears to be associated with good disease control but increased risk of microsomic or macrosomic newborns depending on the medical agent used. CONCLUSIONS In 13 newly described pregnancies along with systematic review of an additional 34 cases indicate that pregnancy in treated acromegalic women can proceed without significant complications or teratogenicity. Medical treatment during pregnancy with DA or SA appears to be associated with altered neonatal weight. Nevertheless, gestation may have a beneficial impact on acromegaly control both during and following pregnancy.

Abstract
The pituitary gland is one of the most affected organs with altered anatomy and physiology during pregnancy. Acromegaly is the second most common pituitary adenoma seen in relation to gestation after prolactinomas. Acromegaly should be treated before conception to prevent potential tumor growth in patients who desire fertility. Medical therapy can be ceased safely after confirmation of pregnancy in acromegalic patients, but octreotide may be used in selected cases with compressive signs. Other hormonal and non-functional tumors are rarer and have been presented as case reports. Sheehan's syndrome, which is one of the most common causes of hypopituitarism in developing countries, and lymphocytic hypophysitis are known to be associated with pregnancy. They usually result in hypopituitarism, sometimes with delays in diagnosis and difficulties in differential diagnosis. Pregnancy is not common among patients with hypopituitarism or pituitary adenomas due to altered gonadotroph functions. Ovulation induction is essential for fertility achievement, but the replacement of other deficient pituitary hormones, including GH, seems to play an important role in the preparation of the uterus for implantation of the embryo.

Abstract
The pituitary gland undergoes much anatomic and physiologic variation during pregnancy. Pituitary disease may have a significant impact on a patient prior to conception as well as throughout her pregnancy. It is imperative to provide care to patients affected by pituitary disease with a multidisciplinary approach involving endocrinologists, obstetricians and, when appropriate, neurosurgical care, as this group of disorders can represent a substantial level of morbidity and mortality for both mother and fetus.

Abstract
Pituitary tumors, usually adenomas, account for about 10-15% of all intracranial tumors. Their treatment, which includes surgery, medicine or radiotherapy, either isolated or in combination, aims to halt tumor growth or achieve tumor shrinkage, as well as control hormone hypersecretion or ensure hormone replacement. Such approaches have made pregnancy possible for women with pituitary adenomas. Medical therapy with dopamine agonists is the treatment of choice for most patients with prolactinomas, with surgery reserved for individuals resistant to drugs. On the other hand, surgery before conception is indicated as a first-line approach in patients with acromegaly, Cushing disease or clinically nonfunctioning pituitary macroadenomas. In these patient populations, medical therapy with somatostatin analogues (acromegaly) or drugs that target the adrenal glands, such as metyrapone and ketoconazole (Cushing disease), should be reserved for those in whom surgery is unsuccessful or contraindicated.

Abstract
OBJECTIVE The Acromegaly Consensus Group met in April 2009 to revisit the guidelines on criteria for cure as defined in 2000. PARTICIPANTS Participants included 74 neurosurgeons and endocrinologists with extensive experience of treating acromegaly. EVIDENCE/CONSENSUS PROCESS: Relevant assays, biochemical measures, clinical outcomes, and definition of disease control were discussed, based on the available published evidence, and the strength of consensus statements was rated. CONCLUSIONS Criteria to define active acromegaly and disease control were agreed, and several significant changes were made to the 2000 guidelines. Appropriate methods of measuring and achieving disease control were summarized.

Abstract
Pregnancy is a rather rare event in acromegaly because fertility is often reduced during active disease. Previous reports of pregnancy in acromegalic patients showed that the pituitary growth hormone (GH) level was unaffected and the insulin-like growth factor (IGF)-1 level was elevated during the second and third trimesters. We describe here a case of persistent acromegaly that showed suppressed levels of GH and IGF-1 during pregnancy. The suppression of GH secretion and IGF-1 may be due to increased estrogen or other factors circulating in mid- to late pregnancy.
