Pregnancy and acromegaly: clinical outcomes of retrospectively analysed data from the German acromegaly registry. Reprod Biol Endocrinol 2024; 22:48. [PMID: 38650041 PMCID: PMC11034139 DOI: 10.1186/s12958-024-01207-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Accepted: 03/16/2024] [Indexed: 04/25/2024] Open
Abstract
CONTEXT Acromegaly is a rare disease caused by excessive growth hormone (GH) secretion, mostly induced by pituitary adenomas. The care of pregnant women with acromegaly is challenging, in part due to existing clinical data being limited and not entirely consistent with regard to potential risks for mother and child. OBJECTIVE To retrospectively examine data on pregnancy and maternal as well as neonatal outcomes in patients with acromegaly. DESIGN & METHODS Retrospective data analysis from 47 pregnancies of 31 women treated in centers of the German Acromegaly Registry. RESULTS 87.1% of the studied women underwent transsphenoidal surgery before pregnancy. In 51.1% a combination of dopamine agonists and somatostatin analogs were used before pregnancy. Three women did not receive any therapy for acromegaly. During pregnancy only 6.4% received either somatostatin analogs or dopamine agonists. In total, 70.2% of all documented pregnancies emerged spontaneously. Gestational diabetes was diagnosed in 10.6% and gravid hypertension in 6.4%. Overall, no preterm birth was detected. Indeed, 87% of acromegalic women experienced a delivery without complications. CONCLUSION Pregnancies in women with acromegaly are possible and the course of pregnancy is in general safe for mother and child both with and without specific treatment for acromegaly. The prevalence of concomitant metabolic diseases such as gestational diabetes is comparable to the prevalence in healthy pregnant women. Nevertheless, larger studies with more data in pregnant patients with acromegaly are needed to provide safe and effective care for pregnant women with this condition.

[PMID: 36359512 PMCID: PMC9689290 DOI: 10.3390/diagnostics12112669] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 10/24/2022] [Accepted: 10/30/2022] [Indexed: 11/06/2022] Open
Abstract
Acromegaly-related sub/infertility, tidily related to suboptimal disease control (1/2 of cases), correlates with hyperprolactinemia (1/3 of patients), hypogonadotropic hypogonadism—mostly affecting the pituitary axis in hypopituitarism (10−80%), and negative effects of glucose profile (GP) anomalies (10−70%); thus, pregnancy is an exceptional event. Placental GH (Growth Hormone) increases from weeks 5−15 with a peak at week 37, stimulating liver IGF1 and inhibiting pituitary GH secreted by normal hypophysis, not by somatotropinoma. However, estrogens induce a GH resistance status, protecting the fetus form GH excess; thus a full-term, healthy pregnancy may be possible. This is a narrative review of acromegaly that approaches cardio-metabolic features (CMFs), somatotropinoma expansion (STE), management adjustment (MNA) and maternal-fetal outcomes (MFOs) during pregnancy. Based on our method (original, in extenso, English—published articles on PubMed, between January 2012 and September 2022), we identified 24 original papers—13 studies (3 to 141 acromegalic pregnancies per study), and 11 single cases reports (a total of 344 pregnancies and an additional prior unpublished report). With respect to maternal acromegaly, pregnancies are spontaneous or due to therapy for infertility (clomiphene, gonadotropins or GnRH) and, lately, assisted reproduction techniques (ARTs); there are no consistent data on pregnancies with paternal acromegaly. CMFs are the most important complications (7.7−50%), especially concerning worsening of HBP (including pre/eclampsia) and GP anomalies, including gestational diabetes mellitus (DM); the best predictor is the level of disease control at conception (IGF1), and, probably, family history of 2DM, and body mass index. STE occurs rarely (a rate of 0 to 9%); some of it symptoms are headache and visual field anomalies; it is treated with somatostatin analogues (SSAs) or alternatively dopamine agonists (DAs); lately, second trimester selective hypophysectomy has been used less, since pharmaco-therapy (PT) has proven safe. MNA: PT that, theoretically, needs to be stopped before conception—continued if there was STE or an inoperable tumor (no clear period of exposure, preferably, only first trimester). Most data are on octreotide > lanreotide, followed by DAs and pegvisomant, and there are none on pasireotide. Further follow-up is required: a prompt postpartum re-assessment of the mother’s disease; we only have a few data confirming the safety of SSAs during lactation and long-term normal growth and developmental of the newborn (a maximum of 15 years). MFO seem similar between PT + ve and PT − ve, regardless of PT duration; the additional risk is actually due to CMF. One study showed a 2-year median between hypophysectomy and pregnancy. Conclusion: Close surveillance of disease burden is required, particularly, concerning CMF; a personalized approach is useful; the level of statistical evidence is expected to expand due to recent progress in MNA and ART.

Abstract
PURPOSE To evaluate the association between acromegaly and pregnancy in terms of disease activity, maternal and fetal outcomes. METHODS This systematic review was conducted according to the Joanna Briggs Institute methodology for systematic reviews of etiology and risk. We focused on observational studies that included pregnant women with acromegaly. The outcomes were acromegaly activity, preterm birth, gestational diabetes, hypertension, eclampsia/preeclampsia, miscarriage, perinatal mortality, low birthweight, small for gestational age, and congenital malformations. Embase, Medline, LILACS, and CENTRAL were our source databases. To perform proportional meta-analyses, we used Stata Statistical Software 17. RESULTS Nineteen studies were included encompassing a total of 273 pregnancies in 211 women with acromegaly. The overall frequency of control of acromegaly during pregnancy was 62%, and of tumor growth was 9%. No fetal or maternal deaths were reported. The overall frequency of worsening of previous diabetes or development of gestational diabetes was 9%, and of previous hypertension or preeclampsia/eclampsia was 6%. The overall frequency of premature labor was 9% [from 17 studies of 263 pregnancies; 95% confidence interval (CI), 5-13%]; of spontaneous miscarriage was 4% (from 19 studies of 273 pregnancies; 95% CI, 2-11%); of small for gestational age was 5% (from 15 studies of 216 newborns; 95% CI, 3-9%); and of congenital malformations was 1% (from 18 studies of 240 newborns; 95% CI, 0-7%). CONCLUSION Pregnancy in women with acromegaly is frequently associated with disease control and is safe in relation to fetal and maternal outcomes, as in women without acromegaly.

Abstract
BACKGROUND Physiological changes in pregnancy may result in significant alterations in endocrine hormone profiles, serum and urine electrolytes and endocrine gland morphology on imaging. Pregnancy-specific pathophysiological processes may also affect the results for endocrine tests. Investigation of endocrine disorders in pregnancy requires knowledge of these changes and awareness of the safety of dynamic hormone testing and imaging for the mother and foetus. OBJECTIVE This review seeks to outline the important physiological changes in pregnancy affecting reference intervals of basal and dynamic endocrine tests in pregnancy and the scenarios in which these changes are clinically significant, the pregnancy-specific disorders that may affect the investigation of endocrine disorders, and the safety of dynamic testing and imaging. CONCLUSION Awareness of the effect of physiological changes, and the potential impact of pregnancy-specific disorders of endocrine tests, and the safety of imaging is crucial to the management of endocrine disorders in pregnancy.

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
INTRODUCTION The prevalence of gestational diabetes (GD) in women with acromegaly is rarely reported. The aims of this study were to evaluate the prevalence of GD in acromegalic women submitted to a systematic screening for GD and then to compare women with or without GD. PATIENTS AND METHODS We studied 14 pregnancies in 11 women (34.0 ± 3.6 years) treated with somatostatin analogues after a pituitary surgery (n = 6) or as primary (n = 5) therapy, and treatment was discontinued at the time of pregnancy diagnosis for 13 pregnancies. One woman was diagnosed with acromegaly during pregnancy and was treated with octreotide LAR between 12 and 18 weeks of gestation. Before pregnancy, no women had diabetes mellitus, and GH/IGF-1 hypersecretion was uncontrolled in 6 women. RESULTS Gestational diabetes was diagnosed during 7 pregnancies (50%) in 6 women (one woman had GD during her 2 pregnancies), according to fasting blood glucose (n = 5) or to an oral glucose tolerance test (n = 2). Before pregnancy, IGF-1 was not controlled in 4 GD+ and in 2 GD- women. Women with GD were not significantly older and had increased pregestational BMI (P = .02), with a more frequent family history of type 2 diabetes, no personal history of GD but of macrosomia for one patient. CONCLUSION The prevalence of GD in our women is higher than that reported in the literature, probably resulting from the systematic GD screening and to the age of women. Therefore, routine screening of GD should be considered in women with acromegaly, particularly in those with risk factors for GD and with uncontrolled IGF-1 levels before pregnancy.

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
Pregnancy in acromegaly is rare and generally safe, but tumour expansion may occur. Managing tumour expansion during pregnancy is complex, due to the potential complications of surgery and side effects of anti-tumoural medication. A 32-year-old woman was diagnosed with acromegaly at 11-week gestation. She had a large macroadenoma invading the suprasellar cistern. She developed bitemporal hemianopia at 20-week gestation. She declined surgery and was commenced on 100 µg subcutaneous octreotide tds, with normalisation of her visual fields after 2 weeks of therapy. She had a further deterioration in her visual fields at 24-week gestation, which responded to an increase in subcutaneous octreotide to 150 µg tds. Her vision remained stable for the remainder of the pregnancy. She was diagnosed with gestational diabetes at 14/40 and was commenced on basal bolus insulin regimen at 22/40 gestation. She otherwise had no obstetric complications. Foetal growth continued along the 50th centile throughout pregnancy. She underwent an elective caesarean section at 34/40, foetal weight was 3.2 kg at birth with an APGAR score of 9. The neonate was examined by an experienced neonatologist and there were no congenital abnormalities identified. She opted not to breastfeed and she is menstruating regularly post-partum. She was commenced on octreotide LAR 40 mg and referred for surgery. At last follow-up, 2 years post-partum, the infant has been developing normally. In conclusion, our case describes a first presentation of acromegaly in pregnancy and rescue of visual field loss with somatostatin analogue therapy. Learning points: Tumour expansion may occur in acromegaly during pregnancy. Treatment options for tumour expansion in pregnancy include both medical and surgical options. Somatostatin analogues may be a viable medical alternative to surgery in patients with tumour expansion 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
Interpretation of laboratory investigations relies on reference intervals. Physiological changes in pregnancy may result in significant changes in normal values for many biochemical assays, and as such results may be misinterpreted as abnormal or mask a pathological state. The aims of this review are as follows: 1. To review the major physiological changes in biochemical tests in normal pregnancy. 2. To outline where these physiological changes are important in interpreting laboratory investigations in pregnancy. 3. To document the most common causes of abnormalities in biochemical tests in pregnancy, as well as important pregnancy-specific causes.

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
OBJECTIVE Data regarding pregnancies in relation to pituitary tumors are limited. The effects of pregnancy on pituitary adenomas and the effects of adenoma itself (hormonal activity, mass effects and pituitary insufficiency) and/or treatment on the ongoing gestation and developing fetus were evaluated. METHODS The study was a retrospective study. A questionnaire involving questions regarding medical history before index gestation, history of related pregnancy, result of index gestation and postpartum follow-up of the patients was filled by the investigator in one of the eight Referral Endocrinology Centers from Turkey. RESULTS One hundred and thirteen (83 prolactinoma, 21 acromegaly, 8 NFPA and 1 plurihormonal pituitary adenoma) pregnancies of 87 (60 prolactinoma, 19 acromegaly, 7 NFPA and 1 plurihormonal pituitary adenoma) patients were reviewed. The clinically important pregnancy-related tumor growth of pituitary adenomas was found to be low in previously treated adenomas. Prolactinomas were more likely to increase in size during pregnancy especially if effective prior treatment was lacking. The risk of hypopituitarism is also minimal due to pituitary adenomas during pregnancy. The results of pregnancies did not differ in patients who were on medical treatment or not for prolactinomas and acromegaly during gestation. Neural tube defect and microcephaly associated with maternal cabergoline use; Down syndrome and corpus callosum agenesis associated with maternal bromocriptine use; unilateral congenital cataract, craniosynostosis and microcephaly associated with maternal acromegaly were detected for the first time. CONCLUSION Medical treatment can be safely done stopped in patients with prolactinoma and acromegaly when pregnancy is confirmed and reinstituted when necessary. Prospective studies may help to determine the effects of medical treatment during gestation on the mother and fetus.

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 In 2007, we published an opinion document to review the role of pegvisomant (PEG) in the treatment of acromegaly. Since then, new evidence emerged on the biochemical and clinical effects of PEG and on its long-term efficacy and safety. AIM We here reviewed the emerging aspects of the use of PEG in clinical practice in the light of the most recent literature. RESULTS The clinical use of PEG is still suboptimal, considering that it remains the most powerful tool to control IGF-I in acromegaly allowing to obtain, with a pharmacological treatment, the most important clinical effects in terms of signs and symptoms, quality of life and comorbidities. The number of patients with acromegaly exposed to PEG worldwide has become quite elevated and the prolonged follow-up allows now to deal quite satisfactorily with many clinical issues including major safety issues, such as the concerns about possible tumour (re)growth under PEG. The positive or neutral impact of PEG on glucose metabolism has been highlighted, and the clinical experience, although limited, with sleep apnoea and pregnancy has been reviewed. Finally, the current concept of somatostatin receptor ligands (SRL) resistance has been addressed, in order to better define the acromegaly patients to whom the PEG option may be offered. CONCLUSIONS PEG increasingly appears to be an effective and safe medical option for many patients not controlled by SRL but its use still needs to be optimized.

Abstract
INTRODUCTION Acromegaly is a rare disorder in which, due to the high incidence of secondary hypogonadism, pregnancies are relatively rare. However, some women with acromegaly do get pregnant, which brings along questions about medication, complications and follow-up. This review tries to address these issues and provide the reader with practical information. METHODS This review summarizes published data. CONCLUSIONS Acromegaly is a disorder that is characterized by changes in growth hormone (GH), insulin-like growth factor-1 (IGF-1) and insulin concentrations and actions. All these hormones are important in pregnancy as well. In principle, the fetal-placental collaboration between mother and child more-or-less takes over the control over GH and IGF-1, not only in normal physiology but also to a certain extend in acromegaly. When medication for the high GH levels or actions is continued during pregnancy, both dopamine agonists, somatostatin analogs and GH receptor antagonists have been used and the available data suggest that there are no adverse consequences on mother or fetus to date. However, it is strongly advised to stop any medical intervention during pregnancy until more data are available on the safety of these compounds. Also, medical treatment is not needed as tumor size and disease activity are not reported to escape.

Abstract
PURPOSE To determine the physical status and intelligence scores of children of acromegalic mothers and to compare them with those of children from mothers without acromegaly. METHODS Six women with acromegaly who became pregnant under follow-up between 2010 and 2014 and their 16 children (group A) were assessed and compared with 16 children of healthy women (group B) and 15 children of women with prolactinoma (group C). The physical examinations of children were performed by the department of pediatric endocrinology and intelligence quotient (IQ) testing was undertaken by adult and pediatric psychiatry departments, using appropriate scales for their ages. RESULTS Six of the 16 children (girls/boys: 7/9) were born after the diagnosis of acromegaly. Five of the 6 pregnancies occured when the patients were taking somatostatin analogs, none continued taking the drugs during pregnancy. The mean IQ of groups A, B, and C were 106.4 ± 12.5, 105.3 ± 12.5, and 103.2 ± 16.1 respectively (p > 0.05). The mean ages, birth percentiles, recent weight and height standard deviation scores were similar between groups (p > 0.05). Two siblings from group A and 1 child from group B were large for gestational age at birth. At recent follow-up, two children from group A were found tall for their age and one from group C was short for his age and was placed under the care of pediatric endocrinology clinic. CONCLUSIONS Pregnancies in acromegaly seems to be uneventful and the general health status and IQ scores of children from women with and without acromegaly were found similar.

Abstract
With advances in surgical and medical treatment and the availability of assisted reproductive techniques, pregnancy in women with acromegaly is more frequently encountered. Diagnosis of acromegaly during pregnancy is difficult because of changes in growth hormone and insulin like growth factor-1 (IGF-1) axis secondary to placental production of growth hormone. The difficulty is compounded by the inability of routine hormone assays to detect placental growth hormone. In the majority of patients with acromegaly, pregnancy does not have an adverse effect on mother or fetus and pituitary mass does not increase in size. The level of IGF-1 usually remains stable because of the effect of estrogen causing a growth hormone resistant state. In patients with pituitary macroadenoma, the possibility of an increase in size of the pituitary mass needs to be kept in mind and more frequent monitoring is required. In case of tumor enlargement, pituitary surgery can be considered in the mid trimester. Experience with the use of medical treatment for acromegaly during pregnancy is increasing. Dopamine agonists, somatostatin analogs or growth hormone receptor antagonists have been used without any adverse consequences on mother or fetus. At present, it is advisable to stop any medical treatment after confirmation of pregnancy till more data are available on the safety of these drugs.

Abstract
Acromegaly is an insidious disease of the pituitary caused by a growth hormone-secreting adenoma. Generally, the diagnosis is made rather late in the course of the disease. Currently, acromegaly can be cured in about half of the patients with the disease by expert surgery. The remainder of non-surgically cured patients often can be effectively treated with somatostatin analogs; either with the new generation of dopaminergic drugs or with Pegvisomant, a GH-receptor blocking agent. However, at the time of diagnosis many patients suffer from serious comorbidities, including hypertension, heart disease, arthrosis, sleep apnea and diabetes mellitus. Recent reports have shown that mortality risk can be normalized. Nevertheless, all efforts should be undertaken to treat comorbidities. New strategies for surgery and medical treatment are discussed.

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
To summarize all available data on pregnancy outcome of acromegaly patients exposed to the growth hormone receptor antagonist pegvisomant (PEGV) during pregnancy as present in the Pfizer's Global Safety Database. Pfizer's Global Safety Database contains adverse event data obtained from the following sources: spontaneous reports, health authorities, Pfizer-sponsored post-marketing surveillance program (ACROSTUDY), customer engagement programs, and clinical studies, reported regardless of outcome. The safety database was searched up to 10th March 2014. From the 35 pregnancy cases, 27 involved maternal [mean age (range) 33.3 years (23-41) and 8 paternal (33.7 years (32-38)] PEGV exposure. Two female patients were reported with two pregnancy cases each. Fetal outcome was normal in 14 (4 paternal) of the 18 reported as live birth, while 4 cases (1 paternal) did not specify the birth outcome. At conception, PEGV mean dose (range) was 15.3 mg/d (4.3-30). In 3 cases of maternal exposure of the 18 cases reporting live birth, PEGV was continued throughout the pregnancy in a dose of 12.1 mg/d (10-15). In 5 cases (all maternal) an elective termination of the pregnancy was performed with no reported fetal abnormalities, 2 cases (maternal) reported a non-PEGV-related spontaneous abortion and in 1 maternal case an ectopic pregnancy occurred. In 9 cases (3 paternal), the fetal outcome was not reported. Three women reported gestational diabetes; one woman continued PEGV treatment during pregnancy. Although the number of reported pregnancies with exposure to PEGV is very small, the presented data reflect the largest series of data available to date and do not suggest adverse consequences of PEGV on pregnancy outcome. Nevertheless, it should be stressed that PEGV should not be used during pregnancy unless absolutely necessary.

Abstract
Pregnancy is becoming a relatively common event in patients with pituitary tumors (PT), due to the increasing availability of medical treatments, which control pituitary diseases associated with the development of PT. However, the presence of PT and its treatment may be a disturbing factor for pregnancy, and pregnancy significantly influences the course and the management of PT. This review summarizes the knowledge about the management of PT during pregnancy and the occurrence of pregnancy in patients with pre-existent PT, focusing on secreting PT characterized by hormonal excess and on clinically non-functioning PT often associated to hormone deficiency, which configure the hypopituitaric syndrome.

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.

INTRODUCTION Biochemical diagnosis of acromegaly relies on measurement of insulin-like growth factor-1 (IGF-1) and growth hormone (GH). An elevated IGF-1 level above the age- and gender-specific normal range and nonsuppression of GH to oral glucose load to a nadir < 0.4 ng/ml in sensitive assays are currently considered diagnostic of acromegaly. Lack of normative data for both IGF-1 and GH across a wide range of populations and ethnicities, interassay and intraassay laboratory variability, pulsatility of GH secretion, and effects of medications and hormones may confound interpretation of these biochemical tests. AREAS COVERED Clinical situations in which acromegaly should be suspected and/or investigated. Strengths and limitations of current IGF-1/GH assays are discussed. Clinical scenarios with discordant GH suppression test and IGF-1 levels and, briefly, acromegaly in pregnancy, prolactin-cosecreting tumors, familial acromegaly, and nonpituitary acromegaly are also discussed. EXPERT OPINION Serum IGF-1 is the cornerstone and in most cases the stand-alone test in the diagnosis and follow-up in patients with acromegaly. Diagnosis depends on the accurate and reliable measurement of serum IGF-1. GH suppression testing is currently used in limited clinical setting. Standardization of IGF-1 assay and development of normative data across a wide population base are needed. Newer bioassays for IGF-1 hold promise for future.

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
Pregnancy in acromegalic patients is a rare event, but is usually uneventful, with stable GH and IGF-I levels and no tumor enlargement. Medical treatment can usually be withdrawn without problems and although no major adverse event has been reported, the suspension of drug treatments is generally recommended. No case report exists in the literature regarding evolution of a somatotropinoma with invasiveness markers throughout pregnancy. We report a case of an acromegalic patient who was submitted to surgery and treated with octreotide LAR maintaining a stable residual tumor and an IGF-I close to the normal levels. Her tumor presented with a high Ki-67 (11.6%) and a low aryl hydrocarbon receptor-interacting protein (AIP) expression. When she became pregnant, octreotide LAR was withdrawn, and despite remaining asymptomatic during pregnancy, tumor growth occurred with compression of surrounding structures. In conclusion, pregnancy in acromegalic patients has usually a favorable prognosis with no tumor growth. However, in the presence of high Ki-67 labeling index and low AIP expression, tumor enlargement may occur and somatostatin analogue treatment throughout the pregnancy should be considered.
