Abstract
PURPOSE Few nationally representative studies have evaluated the epidemiology of PA (pituitary adenoma). This South Korean study evaluated the incidence of different PA subtypes, cardiovascular disease (CVD), and related mortality. METHODS This population-based study evaluated 31,898 patients with PA during 2005-2015. The incidence of PA, mortality, and CVD occurrence in PA cases were evaluated during a median follow-up of 5.3 years (range: 0-10 years). Cox regression analysis was used to evaluate the associations between CVD and mortality. RESULTS The annual incidences (per 100,000 population) were 3.5 for non-functioning pituitary adenoma (NFPA), 1.6 for prolactinoma (PRL), 0.5 for growth hormone-secreting pituitary adenoma (GH), and 0.2 for adrenocorticotropic or thyroid-stimulating hormone-secreting pituitary adenoma (ACTH + TSH). The standardized mortality ratios were 1.9 for ACTH + TSH, 1.7 for NFPA with hypopituitarism, 1.4 for NFPA without hypopituitarism, 1.3 for GH, and 1.1 for PRL. During 2005-2015, the overall incidence of CVD among PA patients was 6.6% (2106 cases), and the standardized incidence ratios were 4.1 for hemorrhagic stroke, 3.0 for ischemic stroke, and 1.7 for acute myocardial infarction. The standardized incidence ratios for stroke were significantly higher in the ACTH + TSH and NFPA groups, which also had higher risks of CVD-related mortality, relative to the PRL and GH groups. CONCLUSION South Korea had a relatively high incidence of NFPA. The incidence of stroke was highest for ACTH + TSH and NFPA, which was directly related to mortality during long-term follow-up. Patients with these types of PA should receive stroke prevention measures to reduce their risk of mortality.

Abstract
CONTEXT Patients with hypopituitarism face excess mortality in the long-term outpatient setting. However, associations of pituitary dysfunction with outcomes in acutely hospitalized patients are lacking. OBJECTIVE The objective of this work is to assess clinical outcomes of hospitalized patients with hypopituitarism with or without diabetes insipidus (DI). DESIGN, SETTING, AND PATIENTS In this population-based, matched-cohort study from 2012 to 2017, hospitalized adult patients with a history of hypopituitarism were 1:1 propensity score-matched with a general medical inpatient cohort. MAIN OUTCOME MEASURES The primary outcome was in-hospital mortality. Secondary outcomes included all-cause readmission rates within 30 days and 1 year, intensive care unit (ICU) admission rates, and length of hospital stay. RESULTS After matching, 6764 cases were included in the study. In total, 3382 patients had hypopituitarism and of those 807 (24%) suffered from DI. All-cause in-hospital mortality occurred in 198 (5.9%) of patients with hypopituitarism and in 164 (4.9%) of matched controls (odds ratio [OR] 1.32, [95% CI, 1.06-1.65], P = .013). Increased mortality was primarily observed in patients with DI (OR 3.69 [95% CI, 2.44-5.58], P < .001). Patients with hypopituitarism had higher ICU admissions (OR 1.50 [95% CI, 1.30-1.74], P < .001), and faced a 2.4-day prolonged length of hospitalization (95% CI, 1.94-2.95, P < .001) compared to matched controls. Risk of 30-day (OR 1.31 [95% CI, 1.13-1.51], P < .001) and 1-year readmission (OR 1.29 [95% CI, 1.17-1.42], P < .001) was higher among patients with hypopituitarism as compared with medical controls. CONCLUSIONS Patients with hypopituitarism are highly vulnerable once hospitalized for acute medical conditions with increased risk of mortality and adverse clinical outcomes. This was most pronounced among those with DI.

Abstract
OBJECTIVE Implication of the tumor size on oncological and functional outcomes of craniopharyngioma is inconsistently reported. The aim of this study is to assess the postoperative outcome of giant craniopharyngiomas (> 4 cm in diameter) and to elucidate the impact of tumor size on various outcome parameters and survival. MATERIAL AND METHODS Forty-four patients (children aged ≤ 18 years: 25; adults: 16) with giant craniopharyngioma, operated between January 2001 and December 2015, were included in this study. Various outcomes, progression-free survival (PFS) and overall survival (OS) were calculated. RESULTS Gross total resection (GTR) was achieved in 17 (39%) and subtotal resection (STR) in 27 (61%) patients. Eleven patients (25%) received radiotherapy (RT) after STR. Postoperatively, new cranial nerve and motor deficits were noted in 12 (27%) and 9 (20%) patients, respectively. Tumor recurrence following GTR and STR without adjuvant RT was diagnosed in 3 (17%), and 5 (38%) patients, respectively. Following STR with RT, one (9%) experienced recurrence. PFS at 5-, and 10- year following GTR, STR, and STR + RT was 80.8%, 45.4%, and 90%, respectively. At 5- and 10- year, OS was 86.5%, 77.9% and 100% following GTR, STR, and STR + RT, respectively. The rate of GTR was significantly lower in patients with giant tumors (39% vs. 62%; Chi-square test, p value 0.008). Postoperatively, neurological deficit (20%), hypopituitarism (95%) and hypothalamic dysfunction (26%) were significantly higher for giant craniopharyngiomas. Hazards of recurrence were not significant between giant and non-giant tumors (hazard ratio 1.86; 95% CI 0.94-3.68; p 0.07). There was no significant difference in OS between the patients with giant and non-giant tumors (log-rank test 2.1; p value 0.14). CONCLUSION Tumor size should be considered as an important predictor of the postoperative functional outcome. Although the rate of GTR is less than that of small tumors, the recurrence rate, progression-free survival, and overall survival of the patients with giant tumor are comparable to non-giant tumors.

Abstract
OBJECTIVE Quality of survival, prognosis and long-term outcome are often severely impaired in childhood-onset craniopharyngioma patients (CP). Identification of risk factors for sequelae such as growth hormone (GH) deficiency is important for appropriate treatment and rehabilitation. DESIGN In a cross-sectional study, 79 CP recruited in HIT-Endo before 2000 were analyzed according to GH substitution: a. CP never GH-treated (noGH); b. CP GH-treated only during childhood (pedGH); c. CP under GH, initiated at adulthood (adultGH); d. CP under GH during childhood and continued during adulthood (contGH). METHODS Progression-free (PFS) and overall survival (OS), height, body mass index (BMI), psychosocial and neuropsychological status (EORTC QLQ-C30, MFI-20). RESULTS OS and PFS rates were similar in all subgroups. ContGH and pedGH CP presented with increases in height (p=0.002; p=0.0001) during long-term follow-up when compared with baseline. In all subgroups except for pedGH, increases in BMI were observed when compared with BMI at diagnosis. For emotional functionality and physical fatigue, adultGH CP showed worse (p=0.037; p=0.034) response (mean: 61.4%; 12.5%) when compared with pedGH CP (mean: 83.5%; 7.7%). Observed differences were not related to irradiation and hypothalamic involvement. In terms of psychosocial status, no differences were observed between subgroups. CONCLUSIONS We conclude that GH substitution was safe with regard to risk of tumor progression/relapse in CP. Growth was improved by GH, whereas the development of obesity was not influenced by GH substitution. However, early initiation of GH substitution after CP diagnosis might have beneficial effects on weight development and neuropsychological outcome.

Abstract
CONTEXT New therapeutic strategies have developed for the management of acromegaly over recent decades. Whether this has improved mortality has not been fully elucidated. OBJECTIVE The primary aim was to investigate mortality in a nationwide unselected cohort of patients with acromegaly. Secondary analyses included time trends in mortality and treatment patterns. DESIGN A total of 1089 patients with acromegaly were identified in Swedish National Health Registries between 1987 and 2013. To analyse time trends, the cohort was divided into three periods (1987-1995, 1996-2004 and 2005-2013) based on the year of diagnosis. MAIN OUTCOME MEASURES Using the Swedish population as reference, standardized mortality ratios (SMRs) were calculated with 95% confidence intervals (CIs). RESULTS Overall SMR was 2.79 (95% CI: 2.43-3.15) with 232 observed and 83 expected deaths. Mortality was mainly related to circulatory diseases (SMR: 2.95, 95% CI: 2.35-3.55), including ischemic heart disease (2.00, 1.35-2.66) and cerebrovascular disease (3.99, 2.42-5.55) and malignancy (1.76, 1.27-2.26). Mortality decreased over time, with an SMR of 3.45 (2.87-4.02) and 1.86 (1.04-2.67) during the first and last time period, respectively (P = .015). During the same time periods, the frequency of pituitary surgery increased from 58% to 72% (P < 0.001) and the prevalence of hypopituitarism decreased from 41% to 23% (P < 0.001). CONCLUSIONS Excess mortality was found in this nationwide cohort of patients with acromegaly, mainly related to circulatory and malignant diseases. Although still high, mortality significantly declined over time. This could be explained by the more frequent use of pituitary surgery, decreased prevalence of hypopituitarism and the availability of new medical treatment options.

Abstract
Non-functioning pituitary adenomas (NFA) are benign pituitary neoplasms not associated with clinical evidence of hormonal hypersecretion. A substantial number of patients with NFA have morbidities related to the tumor and possible recurrence(s), as well as to the treatments offered. Studies assessing the long-term mortality of patients with NFA are limited. Based on the published literature of the last two decades, overall, the standardized mortality ratios in this group suggest mortality higher than that of the general population with deaths attributed mainly to circulatory, respiratory and infectious causes. Women seem to have higher mortality ratios, and assessment of time trends suggests improvement over the years. There is no consensus on predictive factors of mortality but those most consistently identified are older age at diagnosis and high doses of glucocorticoid substitution therapy. Well designed and of adequate power studies are needed to establish the significance of factors compromising the survival of patients with NFA and to facilitate improvements in long-term prognosis.

Abstract
PURPOSE Patients with non-functioning pituitary adenomas (NFPA), especially women, have increased mortality. The aim of this study was to investigate whether mortality in NFPA patients has changed during the last two decades. METHODS This was a nationwide population-based study including 2795 patients (1502 men, 1293 women) diagnosed with NFPA between 1997 and 2011. Patients were identified and followed in Swedish National Health Registries. Standardized mortality ratios (SMRs) with 95 % confidence intervals were calculated for three time periods at first NFPA diagnosis using the general population as reference. RESULTS Mean (±SD) age at NFPA diagnosis was 58.9 ± 16.8 years. Mean (range) follow-up time was 8.3 (0-18) years, resulting in 20,517 patient-years at risk. Surgical treatment and radiotherapy were used in 53 and 5 %, respectively. The prevalence of hypopituitarism was 64 % during the first time period of diagnosis and then declined gradually during the study period (P value for trend <0.0001). The use of pituitary surgery and radiotherapy remained stable. In women, mortality was increased for patients diagnosed between 1997 and 2006 but not for those diagnosed between 2007 and 2011. The SMR in men remained stable throughout the study and did not differ from the general population. During the last time period, 2007-2011, the SMR between men and women did not differ. CONCLUSIONS While mortality in men with NFPA remains normal and stable during the last two decades, mortality in women has declined. Decreasing prevalence of pituitary insufficiency may be a plausible explanation for this positive development.

Abstract
PURPOSE Hypopituitarism is a rare disorder with significant morbidity. To study the evidence on the association of premature mortality and hypopituitarism. METHODS A comprehensive search of multiple databases: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus was conducted through August, 2015. Eligible studies that evaluated patients with hypopituitarism and reported mortality estimates were selected following a predefined protocol. Reviewers, independently and in duplicate, extracted data and assessed the risk of bias. RESULTS We included 12 studies (published 1996-2015) that reported on 23,515 patients. Compared to the general population, hypopituitarism was associated with an overall excess mortality (weighted SMR of 1.55; 95 % CI 1.14-2.11), I 2 = 97.8 %, P = 0.000. Risk factors for increased mortality included younger age at diagnosis, female gender, diagnosis of craniopharyngioma, radiation therapy, transcranial surgery, diabetes insipidus and hypogonadism. CONCLUSION Hypopituitarism may be associated with premature mortality in adults. Risk is particularly higher in women and those diagnosed at a younger age.

Abstract
OBJECTIVE We describe the use of fractionated stereotactic radiotherapy (FSRT) for the treatment of large, invasive, nonfunctioning pituitary adenomas (NFPAs). FSRT is frequently employed for the treatment of residual or recurrent pituitary adenomas. PATIENTS AND METHODS Sixty-eight patients with a large residual or recurrent NFPAs were treated between April 2004 and December 2012, including 39 males and 29 females (median age 51 years). Visual defects were present in 34 patients, consisting of visual field defects (n=31) and/or reduced visual acuity (n=12). Forty-five patients had evidence of partial or total hypopituitarism before FSRT. For most of the patients, the treatment was delivered through 5-10 noncoplanar conformal fixed fields using a 6-MV linear accelerator to a dose of 45 Gy in 25 fractions. RESULTS At a median follow-up of 75 months (range 12-120 months), the 5- and 10-year actuarial local control were 97 and 91%, respectively, and overall survival 97 and 93%, respectively. Forty-nine patients had a tumor reduction, 16 remained stable, and three progressed. The relative tumor volume reduction measured using three-dimensional (3D) magnetic resonance imaging (MRI) was 47%. The treatment was well tolerated with minimal acute toxicity. Eighteen patients developed partial or complete hypopituitarism. The actuarial incidence of new anterior pituitary deficits was 40% at 5 years and 72% at 10 years. No other radiation-induced complications occurred. CONCLUSIONS Our results suggest that FSRT is an effective treatment for large or giant pituitary adenomas with low toxicity.

Abstract
CONTEXT Several previous observational studies showed an association between hypopituitarism and excess mortality. Reports on reduction of standard mortality ratio (SMR) with GH replacement have been published recently. OBJECTIVE This meta-analysis assessed studies reporting SMR to clarify mortality risk in hypopituitary adults and also the potential benefit conferred by GH replacement. DATA SOURCES A literature search was performed in Medline, Embase, and Cochrane library up to March 31, 2014. ELIGIBILITY CRITERIA Studies with or without GH replacement reporting SMR with 95% confidence intervals (95% CI) were included. DATA EXTRACTION AND ANALYSIS Patient characteristics, SMR data, and treatment outcomes were independently assessed by two authors, and with consensus from third author, studies were selected for analysis. Meta-analysis was performed in all studies together, and those without and with GH replacement separately, using the statistical package metafor in R. RESULTS Six studies reporting a total of 19 153 hypopituiatary adults with a follow-up duration of more than 99,000 person years were analyzed. Hypopituitarism was associated with an overall excess mortality (weighted SMR, 1.99; 95% CI, 1.21-2.76) in adults. Female hypopituitary adults showed higher SMR compared with males (2.53 vs 1.71). Onset of hypopituitarism at a younger age was associated with higher SMR. GH replacement improved the mortality risk in hypopituitary adults that is comparable to the background population (SMR with GH replacement, 1.15; 95% CI, 1.05-1.24 vs SMR without GH, 2.40; 95% CI, 1.46-3.34). GH replacement conferred lower mortality benefit in hypopituitary women compared with men (SMR, 1.57; 95% CI, 1.38-1.77 vs 0.95; 95% CI, 0.85-1.06). LIMITATIONS There was a potential selection bias of benefit of GH replacement from a post-marketing data necessitating further evidence from long-term randomized controlled trials. CONCLUSIONS Hypopituitarism may increase premature mortality in adults. Mortality benefit from GH replacement in hypopituitarism is less pronounced in women than men.

Abstract
CONTEXT GH deficiency is associated with changes in body composition, increased cardiovascular risk markers, and reduced bone mineral density. There seem to be multiple causes of the reported increased morbidity and mortality. OBJECTIVE The objective was to study the socioeconomic status in patients with adult-onset GH deficiency and its impact on mortality. DESIGN This is a nationwide registry study in which the socioeconomic status in adult-onset GH deficient patients was identified in the Danish registries and compared with controls matched on age and gender. The socio-economic status included cohabitation, education, income, parenthood, convictions, and retirement. PATIENTS AND CONTROLS All patients had adult-onset GH deficiency and were born between 1950 and 1980. Two-hundred seventy-six patients (53.6% men) and 25 717 controls were included. RESULTS GH-treated patients had a reduced mortality in total and due to malignancy compared with untreated patients. This difference remained after adjustment for cohabitation and education. Compared with the background population, the incidence of cohabitation, parenthood, and convictions was significantly reduced in patients, whereas education was unaffected. Retirement was significantly increased. CONCLUSIONS Mortality was increased in patients, especially among patients not treated with GH. In GH-treated patients, mortality was decreased in total and due to malignancy compared with untreated patients, even after adjustment for all possible measured confounders. The patients had an impaired socioeconomic profile on most parameters compared with controls. This study does not support the suggestion that GH replacement therapy causes increased mortality.

Abstract
CONTEXT Ipilimumab (Ipi) is approved by the Food and Drug Administration for the treatment of unresectable or metastatic melanoma. Little is known about Ipi-induced hypophysitis (IH), an important treatment complication. OBJECTIVE The objectives of the study were as follows: 1) to examine the prevalence of IH, 2) to characterize the clinical course and treatment outcomes in IH, 3) to identify the risk factors for the development of IH, and 4) to determine optimal strategies for the management of IH. DESIGN This was a retrospective review. SETTING The study was conducted at a tertiary referral center. SUBJECTS One hundred fifty-four adult patients with metastatic melanoma were evaluated at Massachusetts General Hospital and were treated with Ipi between March 2008 and December 2013. INTERVENTION(S) The intervention included treatment with Ipi. MAIN OUTCOME MEASURE(S) Pituitary magnetic resonance imaging, pituitary hormone assessment, and patient survival were measured. RESULTS IH was diagnosed in 17 patients (11%). Male gender (P = .02) and older age (P = .005), but not the cumulative dose of Ipi, were risk factors for IH. All patients with IH had anterior hypopituitarism (none had diabetes insipidus). Hypopituitarism was persistent in most individuals (76%). Diffuse pituitary enlargement was observed exclusively in all cases of IH and, upon retrospective review of magnetic resonance imaging scans, this finding preceded the clinical diagnosis of hypophysitis in eight patients. Pituitary enlargement resolved rapidly (within 40 d in seven of seven patients). Median survival in patients with IH was 19.4 vs 8.8 months (P = .05) in the remainder of the cohort. CONCLUSIONS Male gender and older age are risk factors for IH. Pituitary enlargement is sensitive and specific for IH in the appropriate setting, can precede the clinical diagnosis, and resolves rapidly. Anterior pituitary function recovery is uncommon. The incidence of hypophysitis may positively predict survival in melanoma patients treated with Ipi.

Abstract
During the last 20 years a tremendous improvement in the care of patients with pituitary tumors and of hypopituitarism has been achieved. If we resolve most of the possible causes of the increased cardiovascular disease and stroke mortality a normal survival is expected in these patients. Recently, a large population based study showed a decline in the risk of non-fatal stroke and of non-fatal cardiac events in GH deficient patients. This improvement was achieved by complete hormone replacement, including long term GH replacement, together with prescription of cardio protective drugs. If we follow the latest achievements in pituitary imaging, surgery techniques, hormone substitutions, cardio protective medications, we would expect a normal longevity in these patients. This review will focus on; (1) pituitary insufficiencies and hormone substitutions, (2) modes of cranial radiotherapy, and (3) new techniques in the surgery of a pituitary adenoma.

Abstract
PURPOSE OF REVIEW To review the literature with regard to mortality in patients with hypopituitarism with a focus on the role of growth hormone (GH) deficiency and therapy. RECENT FINDINGS Mortality is increased in hypopituitarism, particularly in female patients. In recent years mortality rates appear to be trending downwards towards that of the general population. Recent studies from retrospective or postmarketing surveillance studies have suggested that patients who receive GH therapy may not have increased mortality. Recent studies regarding mortality in paediatric patients treated with GH are conflicting and this area needs further study. SUMMARY There are several important limitations of available data regarding mortality in hypopituitarism and even more so in the impact of GH therapy, which need to be taken into account when interpreting the available data. The data regarding mortality in patients treated with GH as children is an area of much debate and will need further studies to clarify, given the conflicting reports in recent studies.

Abstract
CONTEXT Patients with hypopituitarism have an increased standardized mortality rate. The basis for this has not been fully clarified. OBJECTIVE To investigate in detail the cause of death in a large cohort of patients with hypopituitarism subjected to long-term follow-up. DESIGN AND METHODS All-cause and cause-specific mortality in 1286 Swedish patients with hypopituitarism prospectively monitored in KIMS (Pfizer International Metabolic Database) 1995-2009 were compared to general population data in the Swedish National Cause of Death Registry. In addition, events reported in KIMS, medical records, and postmortem reports were reviewed. MAIN OUTCOME MEASURES Standardized mortality ratios (SMR) were calculated, with stratification for gender, attained age, and calendar year during follow-up. RESULTS An excess mortality was found, 120 deaths vs 84.3 expected, SMR 1.42 (95% confidence interval: 1.18-1.70). Infections, brain cancer, and sudden death were associated with significantly increased SMRs (6.32, 9.40, and 4.10, respectively). Fifteen patients, all ACTH-deficient, died from infections. Eight of these patients were considered to be in a state of adrenal crisis in connection with death (medical reports and post-mortem examinations). Another 8 patients died from de novo malignant brain tumors, 6 of which had had a benign pituitary lesion at baseline. Six of these 8 subjects had received prior radiation therapy. CONCLUSION Two important causes of excess mortality were identified: first, adrenal crisis in response to acute stress and intercurrent illness; second, increased risk of a late appearance of de novo malignant brain tumors in patients who previously received radiotherapy. Both of these causes may be in part preventable by changes in the management of pituitary disease.

Abstract
A craniopharyngioma (CP) is an embryonic malformation of the sellar and parasellar region. The annual incidence is 0.5-2.0 cases/million/year and approximately 60 % of CP are seen in adulthood. Craniopharyngiomas have the highest mortality of all pituitary tumors. Typical initial manifestations at diagnosis in adults are visual disturbances, hypopituitarism and symptoms of elevated intracranial pressure. The long-term morbidity is substantial with hypopituitarism, increased cardiovascular risk, hypothalamic damage, visual and neurological deficits, reduced bone health, and reduction in quality of life and cognitive function. Therapy of choice is surgery, followed by cranial radiotherapy in about half of the patients. The standardised overall mortality rate varies 2.88-9.28 in cohort studies. Patients with CP have a 3-19 fold higher cardiovascular mortality in comparison to the general population. Women with CP have an even higher risk.

Abstract
INTRODUCTION Hypopituitarism is associated with higher prevalence of cardiovascular risk factors and premature death. Furthermore, some clinical and therapeutic features of hypopituitarism have been associated with a worse prognosis. OBJECTIVE We reviewed, retrospectively, a large series of adult patients with hypopituitarism using stringent epidemiological criteria. Prevalence, association with cardiovascular risk factors, mortality and survival have been analysed. DESIGN AND METHODS Two hundred and nine adult hypopituitary patients (56·9% females) from a population of 405 218 inhabitants, followed for 10 years. RESULTS Prevalence of hypopituitarism at the end of the study was 37·5 cases/100 000 inhabitants. Incidence of hypopituitarism was 2·07 cases/100 000 inhabitants and year. Thirty-two patients died during the period of the study. Standardized mortality rate (SMR) was 8·05, higher in males (8·92 vs 7·34) and in younger patients (84·93 vs 5·26). Diagnosis of acromegaly (P = 0·033), previous radiotherapy (P = 0·02), higher BMI (P = 0·04), diabetes mellitus (P = 0·03) and cancer (P < 0·0001) were associated with mortality. A lower survival was associated with older age at diagnosis, nontumoural causes, previous radiotherapy, diabetes mellitus with poor metabolic control and malignant disease. CONCLUSIONS Prevalence of hypopituitarism was 37·5 cases/100 000 inhabitants, and annual incidence was 2·07 cases/100 000 inhabitants. SMR was 8 times higher in hypopituitarism than in general population and was also higher in males and younger patients. Reduced survival was significantly related to cancer, nontumoural causes of hypopituitarism, older age at diagnosis, previous radiotherapy and diabetes mellitus with poor metabolic control.

Abstract
OBJECTIVE Hypopituitarism is associated with an increased mortality rate but the reasons underlying this have not been fully elucidated. The purpose of this study was to evaluate mortality and associated factors within a large GH-replaced population of hypopituitary patients. DESIGN In KIMS (Pfizer International Metabolic Database) 13,983 GH-deficient patients with 69,056 patient-years of follow-up were available. METHODS This study analysed standardised mortality ratios (SMRs) by Poisson regression. IGF1 SDS was used as an indicator of adequacy of GH replacement. Statistical significance was set to P<0.05. RESULTS All-cause mortality was 13% higher compared with normal population rates (SMR, 1.13; 95% confidence interval, 1.04-1.24). Significant associations were female gender, younger age at follow-up, underlying diagnosis of Cushing's disease, craniopharyngioma and aggressive tumour and presence of diabetes insipidus. After controlling for confounding factors, there were statistically significant negative associations between IGF1 SDS after 1, 2 and 3 years of GH replacement and SMR. For cause-specific mortality there was a negative association between 1-year IGF1 SDS and SMR for deaths from cardiovascular diseases (P=0.017) and malignancies (P=0.044). CONCLUSIONS GH-replaced patients with hypopituitarism demonstrated a modest increase in mortality rate; this appears lower than that previously published in GH-deficient patients. Factors associated with increased mortality included female gender, younger attained age, aetiology and lower IGF1 SDS during therapy. These data indicate that GH replacement in hypopituitary adults with GH deficiency may be considered a safe treatment.

Abstract
It is now accepted that adults with severe GH deficiency (GHD) demonstrate impaired physical and psychological well-being and may benefit from replacement with recombinant human GH. Post-marketing surveillance surveys, such as the Pfizer International Metabolic Database (KIMS), were initially set-up to provide safety data on long-term treatment but have the added benefit of providing ongoing observational data on the effect of GH replacement on body composition, lipid and glucose status, hypertension, bone density and quality of life. These data demonstrate that although GHD has clinical impact at all ages, the individual consequences of this condition may take on greater significance at different stages in life. At all ages, accurate, safe diagnosis and appropriate GH dosing are necessary to provide the individual with the best possible outcome.

Abstract
The hypothalamic-pituitary unit is a particularly radiosensitive region in the central nervous system. As a consequence, hypopituitarism commonly develops after radiation treatments for sellar and parasellar neoplasms, extrasellar brain tumours, head and neck tumours, and following whole body irradiation for systemic malignancies. Increasing tumour-related survival rates provide an expanding population at risk of developing hypopituitarism. In this population, long-term monitoring tailored to the individual risk profile is required to avoid the sequelae of untreated pituitary hormonal deficiencies and resultant decrease in the quality of life. This review analyses the pathogenesis, prevalence and consequences of radiation-induced hypopituitarism (RIH) in diverse subgroups at risk. Also discussed is the impact of modern radiotherapy techniques in the prevalence of RIH, the spectrum of endocrine disorders and radiation-induced brain conditions that also occur in patients with RIH.

Abstract
OBJECTIVE Dopamine agonists are the first line therapy for the treatment of prolactinomas. The aim of this study was to assess the outcome of macroprolactinomas during long-term follow-up after initial treatment with dopamine agonists. DESIGN Retrospective follow-up study. PATIENTS We included 72 consecutive patients (age 39+/-17 years, men 46%) diagnosed with macroprolactinoma, and initially treated with dopamine agonists between 1980 and 2004. RESULTS Initial presentation included headache in 49%, and visual field defects in 38% of the patients. Nine patients were already treated with dopamine agonists at presentation. Median prolactin level of the untreated patients was 460 microg/L (range 96-35,398 microg/L) at presentation. Hypopituitarism, other than hypogonadism, was present in 6% of the patients. Mean duration of follow-up was 10.2+/-6.1 years. Additional transsphenoidal surgery was necessary in 35% of the patients, because of resistance and/or intolerance of dopamine agonists. Postoperative radiotherapy was provided to 18% of all patients. During long-term follow-up, normoprolactinemia was present in 85% of the patients, but biochemical remission (normal prolactin levels in the absence of dopamine agonists) was present in only 22% of the patients. Tumor shrinkage was evident on MRI in 57% of the patients. Hypopituitarism developed in 39% of the patients, especially in those who received additional surgery with or without radiotherapy. CONCLUSION Dopamine agonists are effective in normalizing prolactin values, and inducing tumor shrinkage. However, in one-third of the patients, additional therapy was necessary due to dopamine agonist resistance and/or intolerance, associated with a high incidence of hypopituitarism.

Abstract
The increased mortality associated with acromegaly was first demonstrated in early epidemiological studies. Since the seminal paper by Wright et al. in 1970, nearly 20 studies have analyzed mortality rates in over 5,000 patients with acromegaly. Overall standardized mortality rates are approximately two times higher than in the general population, relating to an average reduction in life expectancy of around 10 years. The excess deaths are due predominantly to cardiovascular, cerebrovascular and respiratory disease. Malignancy deaths have been high in some studies but not others; in the largest series looking at cancer mortality in acromegaly, overall cancer deaths were not increased, but colon cancer mortality was higher than expected. In 1993, Bates et al. first demonstrated that outcome was related to the latest measurable growth hormone (GH), and treatment to reduce GH levels led to improved outcomes. Other factors predicting poor outcome include the presence of hypertension and diabetes. On the basis of current evidence, a latest GH of less than 2-2.5 mug/L is a better predictor of good outcome than a normal insulin-like growth factor-1 (IGF-1), possibly due to discrepancy between GH and IGF-1 at low GH levels. There is some evidence to suggest a more stringent GH cut-off (less than 1 mug/L) may yield additional benefit but further studies are required to investigate any added risk of increased mortality from hypopituitarism. Radiotherapy has been linked specifically to cerebrovascular mortality and its use in patients with acromegaly must involve a careful risk-benefit analysis in each case.

Abstract
BACKGROUND Increased mortality has been reported in patients with pituitary disease, with some studies showing higher standard mortality rates (SMR) in women than in men. OBJECTIVE To assess overall SMR for men and women with benign pituitary disease without excessive ATCH or GH secretion and to investigate associations between SMR and time period of diagnosis. DESIGN From searches in PubMed, Embase and Web of Science databases, and reference lists of major reviews and original articles, we included original studies providing SMR values and 95% confidence intervals (CI) for men and women separately. Thirty articles were studied in detail. Six studies were eligible for the meta-analysis of sex-specific mortality, and seven for the analysis of association between SMR and diagnosis period. RESULTS Individual studies (total 5412 patients) reported total SMR values (men and women together) ranging from 1.21 to 3.80. SMR varied from 0.98 to 3.36 in men and from 2.11 to 4.54 in women. Weighted SMR values were significantly higher in women (2.80; CI 2.59-3.02) than in men (2.06; CI 1.94-2 20) (P < 0.0001). SMR was negatively correlated with first year of diagnosis in individual studies (partial correlation analysis controlling for sex, P = 0.017), and approached normal in recent studies in men but not in women. CONCLUSIONS In our meta-analysis of patients with pituitary disease without ACTH or GH excess, SMR was significantly higher in women than in men. SMR reached normal levels in men treated in recent decades, but remained elevated in women.

Abstract
BACKGROUND Gamma knife radiosurgery (GKR) is an adjuvant treatment for acromegaly if surgery fails to normalize GH hypersecretion. OBJECTIVE To examine the effect of GKR on tumor growth and hypersecretion, and to characterize the adverse effect of this treatment. DESIGN Cross-sectional follow-up study. First, retrospective data pre- and post-GKR were collected. PATIENTS then underwent a predefined survey including radiological, endocrinological, ophthalmological, and neurosurgical evaluation. SETTING Norwegian National Center for gamma knife treatment. PATIENTS Sixty-one patients treated with GKR for acromegaly. Out of 55, 53 living patients underwent a detailed survey. The mean follow-up was 5.5 years. No patient was lost to follow-up. RESULTS Tumor growth was stopped in all patients. At 3, 5, and 10 years after GKR, 45, 58, and 86% of patients had normal IGF-I levels. Consecutive hormone value analysis showed that patients receiving GH-suppressive medication had a more rapid decline in hypersecretion than those who did not receive such medication. Evaluated by survey baseline values alone, non-elevated IGF-I and GH levels below 5 mIU/l were found in 38%. GH-suppressive medication was terminated in 16 out of 40 patients following GKR. Nine out of 53 surveyed patients (17%) had normal IGF-I and GH nadir below 2.6 mIU/l at glucose tolerance tests, while not on hormone-suppressive medication. Two patients developed minor visual field defects. Eight patients started hormone substitution therapy during the follow-up period. CONCLUSION GKR is an effective adjuvant treatment for residual acromegaly, carrying few side effects.

Abstract
BACKGROUND AND OBJECTIVE Previous studies on hypopituitarism and mortality have concluded that insufficient pituitary function is associated with decreased survival. For several reasons the results are difficult to compare - particularly because definitions and treatment of hypopituitarism have varied and various underlying disorders have been included. The purpose was to assess the relationship between mortality and pituitary function. PATIENTS AND DESIGN One hundred and sixty consecutive patients (99 men and 61 women) with functionless, suprasellar pituitary adenoma. All were operated on transsphenoidally during the period 1985-1996. Additional radiotherapy was given to 29 patients. Mortality was calculated 12.4 years (median, range 8.1-19.9) after operation. Postoperative hormonal deficits were treated in most, though GH substitution was given only to a minority of patients. RESULTS Postoperatively 30% of the patients had normal pituitary function (normal adrenocortical, thyroid and gonadal function), 26% were panhypopituitary and 36% had partial pituitary insufficiency. Forty-one patients had died (34.7 expected) yielding a standard mortality ratio (SMR) of 1.18 (95% confidence limits (CI) 0.87-1.60). SMR was significantly increased in women (1.97, CI 1.20-3.21) but not in men (0.83, CI 0.55-1.26). SMR in patients with normal pituitary function, panhypopituitarism and partial insufficiency were not different from that in the general population. SMR in hypopituitary women was substantially higher than in men with pituitary insufficiency. Treatment with growth hormone in GH-deficient patients did not influence survival. CONCLUSION Pituitary surgery for nonfunctioning adenoma and subsequent pituitary insufficiency had no effect on mortality in men, but was associated with significantly increased mortality in women. Suboptimal hormonal substitution in women may play a role.

Abstract
OBJECTIVE In epidemiological studies, hypopituitary adults show increased mortality compared with population controls. Patients with hypopituitarism caused by a craniopharyngioma (CP) and/or its treatment have a higher mortality than patients with other etiologies, such as a nonfunctioning pituitary adenoma (NFPA). To analyze this difference, we used the KIMS database (Pfizer International Metabolic Database) comparing CP and NFPA patients in terms of baseline characteristics and responses to GH replacement. PATIENTS Baseline characteristics were studied in 351 CP patients (189 men and 162 women; mean age, 42.5 yr) and compared with 370 NFPA patients, matched for age and sex (185 men and 185 women; mean age, 42.5 yr). The effects of 2 yr of GH replacement were analyzed in a subgroup of 183 CP and 209 NFPA patients. RESULTS At baseline, both CP and NFPA patients had characteristic features of GH deficiency, with low serum IGF-I, increased body fat, dyslipidemia, and reduced quality of life. Male CP patients were significantly more obese (30.0 vs. 28.2 kg/m2; P = 0.0003) compared with NFPA patients, had a higher waist/hip ratio (P = 0.004), higher triglycerides (P = 0.003), and lower high-density lipoprotein cholesterol (P = 0.03). Similar, but much smaller, differences were seen in female CP compared with NFPA patients, only reaching significance for waist/hip ratio (P = 0.05) and triglycerides (P = 0.0004). CP patients had more often undergone surgery by the transcranial route (68.8% vs. 30.9%; P < 0.0001), and panhypopituitarism was more prevalent in CP than in NFPA patients (58.7% vs. 19.8%; P < 0.0001). The incidence of previous fractures, hypertension, coronary heart disease, claudication, and diabetes mellitus was high, but not different, between CP and NFPA patients. After 2 yr of GH replacement therapy, similar significant improvements were evident in both groups in fat-free mass, total and low-density lipoprotein cholesterol, and Quality-of-Life-Assessment in GH Deficient Adults score compared with baseline. In contrast to NFPA patients, CP patients had no significant decrease in body fat with GH therapy. CONCLUSIONS In the KIMS database, patients with CP have more often undergone surgery by the transcranial route than patients with NFPA, have a higher prevalence of pituitary deficiencies, are more obese (predominantly males), and have more dyslipidemia. This could provide an explanation, at least in part, for the higher mortality rate in CP patients observed in epidemiological studies. CP patients respond equally well to GH therapy in fat-free mass, lipids, and quality of life, but are less likely to lose body fat. We assume that this difference in response merely reflects the stronger tendency of CP patients to accumulate fat over time.

Abstract
Hypopituitarism is a disease complex characterised by varying pituitary hormonal deficiencies. The causes and manifestations of hypopituitarism are diverse, the most common being the presence of or treatment of a pituitary adenoma. Pressure effects from the tumour itself on normal pituitary tissue, together with the effects of surgical resection, results in variable degrees of hypopituitarism. The latter precipitates end-organ failure leading to a variety of symptoms and signs, which are often nonspecific and vague. The broad aims of managing patients with hypopituitarism are to provide amelioration of the symptomatology associated with the condition, to avoid potentially acute life-threatening complications and to protect against long-term sequelae that may include osteoporosis and cardiovascular disease. This is achieved through lifelong therapeutic replacement of target hormonal deficiencies, such as corticosteroids or sex hormones, or replacement of the pituitary hormones themselves (i.e., growth hormone and vasopressin). Although the general principle of replacing missing hormones seems straightforward, in reality, existing hormonal therapeutic regimes often result in unphysiological replacement. Furthermore, there may be problems associated with their administration and routine monitoring. There is now little doubt that the hypopituitary state is associated with increased cardiovascular mortality. However, the precise underlying mechanisms responsible have not been fully elucidated, but probably include untreated growth hormone deficiency and/or unphysiological replacement of other target hormones. An effective strategy of tailoring hormonal replacement regimes to individual needs remains a challenge but is imperative if the increased morbidity and mortality associated with hypopituitarism is to be addressed.

Abstract
Growth hormone (GH) acts predominantly via insulin-like growth factor-I (IGF-I) expression. Acromegaly is associated with an increased mortality which can be reversed by optimal treatment. Somatostatin analogues are effective adjunctive therapies in patients treated with surgery and/or radiotherapy and result in tumour shrinkage in many patients. Pegvisomant is a GH analogue which inhibits functional dimerization of GH receptors, inhibits GH activity and normalizes IGF-I in over 90% of subjects. Adult GH deficiency is associated with changes in body composition, insulin status, lipid profile and Quality of Life measures. Hypopituitarism is associated with an increased mortality. Replacement with GH has clinically beneficial effects but there are no data on effects on mortality. Taller individuals are at a 20-60 percent increased risk of a range of cancers, an effect that may be mediated via IGFs. These observations suggest that there is an optimal level of circulating GH and IGF-I required to maintain normal health.

Abstract
OBJECTIVES The direct causes of death in Japanese patients with hypopituitarism remain unclear. In this study, the direct causes of death were investigated and compared between Japanese patients with hypopituitarism from a nation-wide autopsy database and an age- and gender-matched control population from national reports. SUBJECTS Three hundred and ninety-one subjects with hypopituitarism who had died were selected from a nation-wide autopsy database (1984-1993). The ratios of each cause of death among the age- and gender-matched control population were derived from national reports. RESULTS In subjects with hypopituitarism, an increased relative frequency of death from cerebrovascular diseases (male; 2.02 (95% confidence interval (CI) 1.45-2.82), female; 1.73 (95% CI 1.18-2.52)) was found. In particular, the relative frequency of death from cerebral hemorrhage was 4.60 (95% CI 2.95-7.17) in male and 4.80 (95% CI 2.90-7.94) in female subjects with hypopituitarism. Unexpectedly, a decreased relative frequency of death from all heart diseases (male; 0.439 (95% CI 0.277-0.696), female; 0.267 (95% CI 0.149-0.478)) was found in subjects with hypopituitarism, although there was no difference between subjects with hypopituitarism and controls in the frequency of death from ischemic heart disease. CONCLUSIONS These results provide useful information for the long-term care of Japanese patients with hypopituitarism.

Abstract
Human growth hormone is now readily available and approved for treatment of the growth hormone deficiency syndrome in adults. However, physicians have been slow to adopt this therapeutic modality. Reasons for skepticism about the use of growth hormone for the growth hormone deficiency syndrome include doubts about whether growth hormone deficiency causes increased morbidity and mortality in patients with hypopituitarism; availability of highly efficacious, easier to use, and less expensive agents for certain aspects of the growth hormone deficiency syndrome, especially cardiovascular disease; and concerns about possible toxicity in adults. Long-term studies in patients receiving appropriate comprehensive management for other hormonal deficiencies and for concomitant abnormalities will be required to convince physicians of the utility and safety of growth hormone replacement therapy.

Abstract
Growth hormone as therapy for adults with growth hormone deficiency has not been universally accepted by endocrinologists who treat adult patients. The following are addressed in this commentary: the evidence on safety and efficacy in the literature supporting the idea that growth hormone should be offered as replacement therapy to adults who are growth hormone deficient; common concerns of the average prescribing endocrinologist, including the purported association between insulin-like growth factor-I and malignant neoplasms and quality-of-life issues with long-term therapy; and controversial subjects, such as differences in dosing for adults versus children and diagnostic issues. This analysis should encourage reluctant practitioners to at least consider growth hormone replacement therapy for patients with definite growth hormone deficiency--that is, patients with symptomatic panhypopituitarism.

Abstract
BACKGROUND Four retrospective studies have reported premature mortality in patients with hypopituitarism with standard mortality ratios (SMRs) varying between 1.20 and 2.17. Patients with hypopituitarism have complex endocrine deficiencies, and the mechanisms underpinning any excess mortality are unknown. Furthermore, the suggestion has emerged that endogenous growth-hormone deficiency might account for any excess mortality. We aimed to clarify these issues by doing a large prospective study of total and specific-cause mortality in patients with hypopituitarism. METHODS We followed up 1014 UK patients (514 men, 500 women) with hypopituitarism from January, 1992, to January, 2000. 573 (57%) patients had non-functioning adenomas, 118 (12%) craniopharyngiomas, and 93 (9%) prolactinomas. SMRs were calculated as the ratio of observed deaths to the number of deaths in an age-matched and sex-matched UK population. FINDINGS The number of observed deaths was 181 compared with the 96.7 expected (SMR 1.87 [99% CI 1.62-2.16], p<0.0001). Univariate analysis indicated that mortality was higher in women (2.29 [1.86-2.82]) than men (1.57 [1.28-1.93], p=0.002), in younger patients, in patients with an underlying diagnosis of craniopharyngioma (9.28 [5.84-14.75] vs 1.61 [1.30-1.99], p<0.0001), and in the 353 patients treated with radiotherapy (2.32 [1.71-3.14] vs 1.66 [1.30-2.13], p=0.004). Excess mortality was attributed to cardiovascular (1.82 [1.30-2.54], p<0.0001), respiratory (2.66 [1.72-4.11], p<0.0001), and cerebrovascular (2.44 [1.58-4.18], p<0.0001) causes. There was no effect of hormonal deficiency on mortality, except for gonadotropin deficiency, which, if untreated was associated with excess mortality (untreated 2.97 [2.13-4.13] vs treated 1.42 [0.97-2.07], p<0.0001). Multiple regression analyses identified age at diagnosis, sex, a diagnosis of craniopharyngioma, and untreated gonadotropin deficiency as independent significant factors affecting mortality. INTERPRETATION Patients with hypopituitarism have excess mortality, predominantly from vascular and respiratory disease. Age at diagnosis, female sex, and above all, craniopharyngioma were significant independent risk factors. Specific endocrine-axis deficiency, with the exception of untreated gonadotropin deficiency, does not seem to have a role.

Abstract
A retrospective analysis was conducted to examine the long-term outcome of surgery, by a single pituitary surgeon and radiotherapy for acromegaly at Groote Schuur Hospital, Cape Town, using modern criteria for the definition of cure. Seventy-two patients (F/M ratio 1.3:1), aged 16-74 years, were eligible for inclusion. The mean follow-up period was 8.3 years. Macroadenomas were present in 79%, microadenomas in 15% and tumour size was not documented in 6%. Pretreatment GH levels were, > or = 40 m U/l in 56 patients. Postoperatively, 21% of patients were cured, 40% controlled and 40% had hypopituitarism. After radiotherapy (mean follow-up 8.7 years) 43% were cured, 66% controlled and 78% had hypopituitarism. At follow-up 37% of patients traced had died. The most common cause of death was vascular disease. The poor surgical results may be attributed to late presentation in the developing world setting, as evidenced by tumour size and invasiveness, and the degree of GH elevation. Emphasis on early diagnosis of non-invasive tumours is necessary to improve the cure rate and reduce mortality,

Abstract
Hitherto four relevant cohort studies have been published on the life expectancy of patients with hypopituitarism, two from the UK and two from Sweden. In all four studies patients with acromegaly or Cushing's disease were excluded, and patients with GH replacement were not included. A crude meta-analysis, not considering differences in validity of the study designs, gives an overall Relative Risk (RR) of 1.47, with a relatively small 95% confidence interval of 1.27-1.70. The aim of this critical review was to assess whether lacking validity in the design of one or several of these studies indicates that the true RR might be higher or lower than indicated by meta-analyses. A high frequency of cranial irradiation in one of the Swedish cohorts may explain part of the very high observed RR for cerebrovascular mortality, but there remained a 40% risk increase for cardiac diseases that cannot be explained by irradiation. Some other validity problems, especially seen in the UK studies, will result in under-estimation of the true RR, but for others the direction of bias is uncertain due to lacking information in the original publications. According to our view, it is more probable that the observed overall 50% risk increase for vascular mortality is an under-estimation than an over-estimation of the true RR. This analysis is of a qualitative nature, and it is not possible to quantify to what extent the lacking validity may have affected the RR.

Abstract
PURPOSE Local control for pituitary adenomas treated with external beam radiation therapy was retrospectively analyzed to evaluate the efficacy of radiation. MATERIALS AND METHODS Thirty-eight patients treated with radiation therapy between 1979 and 1994 were analyzed. The median age was 46. Nineteen newly diagnosed tumors were treated with surgery and radiation therapy, while the others were recurrent cases. Twenty-two tumors were non-functioning, while 10 produced growth hormone (GH) and three each were prolactin-, and adrenocorticotropic hormone (ACTH)-producing tumors. The median-radiation dose was 50 Gy in 25 fractions. RESULTS Non-functioning adenomas and prolactin-producing adenomas were completely controlled, judging from the absence of tumor progression on neuroimaging studies and clinical symptoms, and normalization of the serum prolactin level (< 25 ng/ml). On the other hand, local control was obtained in only one of the 3 patients with ACTH-producing adenomas, and the control rate at 10 years was only 46% for GH-producing adenomas. Panhypopituitarism developed in 35% of the patients after radiation therapy. No other serious complications were noted. CONCLUSION Non-functioning pituitary adenomas and prolactin-producing adenomas were well controlled with external radiation therapy combined with surgery. However, dose escalation might be necessary to control GH-or ACTH-producing tumors. It is important to replace corticosteroid hormone and thyroid hormone in many patients.

Abstract
OBJECTIVE Hypopituitarism, predominantly although not exclusively due to nonfunctioning pituitary tumours, has been associated with reduced life expectancy. Mortality from vascular diseases contributed significantly to the overall increase in mortality in some, but not all of the studies published to date. The aim of this study was to contribute further data to the debate regarding the putative association of vascular mortality with hypopituitarism. DESIGN AND PATIENTS A retrospective case note review of patients undergoing pituitary surgery in Birmingham, between 1/1/70 and 1/1/92. Subjects were identified from neurosurgical and neuropathology records. 348 patients were identified of which 197 were male (median age at surgery 48.4, range 11-79 years) and 151 female (median age at surgery 47.8, range 9-78 years). All cause mortality and mortality from vascular disease was compared to the general population of the UK using the Person Years computer programme. RESULTS There was a small increase in all cause mortality (SMR 1.2; 95% CI 0.95-1.55), but this was not statistically significant in this study (P = 0.06). Mortality from vascular disease was reduced (SMR 0.7; 95% CI 0.5-1.1; P = 0.03) particularly in the female cohort (SMR 0.5; 95% CI 0.2-1.0; P < 0.01) with the male subjects having similar mortality to that expected in an age and sex matched control population (SMR 0.9; 95% CI 0.5-1.4; P = 0.26). CONCLUSION Although patients with pituitary deficiency may be subject to a small increase in all cause mortality, the results of this study do not support the view that hypopituitarism is associated with a significant increase in vascular disease. There is a pressing need for a large prospective study with comprehensive data collection, including both endocrine data and information regarding clinical outcome, to clarify this issue. In the interim it would seem prudent to base the need for GH replacement therapy on quality of life issues rather than any potential for increased longevity.

Abstract
Untreated growth hormone deficiency (GHD) might explain the increased mortality reported in patients with hypopituitarism. These statistics appear to be largely attributable to cardiovascular disease. Differences in fibrinolytic activity regulators, together with dyslipidaemias, abdominal obesity and raised blood pressure in hypopituitarism might explain this increased risk. There is growing evidence that treatment with growth hormone (GH) can rectify most of the cardiovascular abnormalities associated with GHD. The reported improved psychosocial well-being in response to GH treatment may also be important in lowering risk in this group of patients.

Abstract
The issue of whether hypopituitarism is a risk factor for increased mortality from all causes, and particularly from vascular disease, has been evaluated in four retrospective analyses. In all studies, all-cause mortality was significantly increased by 1.3-2.2-fold compared to age- and sex-matched cohorts. The increase in vascular mortality was significant in the two studies from Sweden (1.8-1.9-fold) but not in the two from the UK (0.8-1.4-fold). The total number of deaths relating to all-cause and vascular mortality was relatively small, and the 95% confidence intervals on the observed to expected (O/E) mortality ratios were wide, in some instances crossing the unity line. As retrospective epidemiological studies, these trials suffer from several drawbacks. They included small numbers of patients and events (i.e. deaths), and determination of the number of deaths and their causes may be incomplete, with small additions or subtractions impacting on O/E mortality ratios. A precise diagnosis of pituitary hormone deficiency in patients recruited in the earlier years of the studies (pre-1965) often relied on historical details and not on firm biochemical values. None of the studies provided any measurement of growth hormone status for the cohorts, and in only one study was there any relationship between a particular axis deficiency and all-cause mortality. This finding suggested that hypogonadal subjects were relatively protected compared with eugonadal counterparts. However, this must be regarded as a preliminary conclusion. These retrospective studies indicate that there are no data to support a relationship between vascular or all-cause mortality in hypopituitarism and growth hormone deficiency. Nevertheless, they do provide preliminary evidence to suggest that it would be worthwhile to conduct a large, multicentre, prospective study of well-characterized and documented patients with a sufficient number of events, in order to establish definitively the relationship between various axis deficiencies and mortality.

OBJECTIVE An increased prevalence of atherosclerosis has been shown among patients with hypopituitarism. The aim of the present study was to assess whether patients with hypopituitarism experience increased cardiovascular, in particular cerebrovascular, mortality. DESIGN AND PATIENTS Retrospective cohort study of mortality, 1952-1992, in 344 patients, of whom 130 were female, receiving conventional hormone replacement for hypopituitarism following neurosurgery for pituitary tumours. The general population in the catchment area of southern Sweden from which the patients were recruited constituted the reference population. Expected mortality was obtained from cause, sex, calendar year, and 5-year age-specific death raise for the area. RESULTS Increased mortality from cerebrovascular disease (standardized mortality ratio (SMR) 3.39; 95% CI 2.27-4.99) was the main contributor to the increased overall cardiovascular mortality (SMR 1.75; 95% CI 1.40-2.19). The increase in mortality from cardiac diseases was much smaller (SMR 1.41; 95% CI 1.04-1.88). The risk for cerebrovascular death was higher in women (SMR 4.91) than in men (SMR 2.64). The relative risk for cerebrovascular death was independent of the time interval since diagnosis of pituitary insufficiency, but was greater in subjects diagnosed at an earlier age (< 55 years). No increased mortality in malignant tumours was observed (SMR 0.95; 95% CI 0.60-1.48). CONCLUSION The increased cerebrovascular mortality may be due to GH deficiency, or to long-term lack or inadequacy of substitution for other pituitary hormones. The observations that an early onset of pituitary insufficiency and female sex are predictors for a high risk for cerebrovascular mortality merit particular attention when treating this group of patients.
