Abstract
CONTEXT Insight into the current landscape of patient-reported outcome (PRO) measures (PROM) and differences between PROs and conventional biochemical outcomes is pivotal for future implementation of PROs in research and clinical practice. Therefore, in studies among patients with acromegaly and growth hormone deficiency (GHD), we evaluated (1) used PROMs, (2) their validity, (3) quality of PRO reporting, (4) agreement between PROs and biochemical outcomes, and (5) determinants of discrepancies. EVIDENCE ACQUISITION We searched 8 electronic databases for prospective studies describing both PROs and biochemical outcomes in acromegaly and GHD patients. Quality of PRO reporting was assessed using the International Society for Quality of Life Research (ISOQOL) criteria. Logistic regression analysis was used to evaluate determinants. EVIDENCE SYNTHESIS Ninety studies were included (acromegaly: n = 53; GHD: n = 37). Besides nonvalidated symptom lists (used in 37% of studies), 36 formal PROMs were used [predominantly Acromegaly Quality of Life Questionnaire in acromegaly (43%) and Quality of Life-Assessment of Growth Hormone Deficiency in Adults in GHD (43%)]. Reporting of PROs was poor, with a median of 37% to 47% of ISOQOL items being reported per study. Eighteen (34%) acromegaly studies and 12 (32%) GHD studies reported discrepancies between PROs and biochemical outcomes, most often improvement in biochemical outcomes without change in PROs. CONCLUSIONS Prospective studies among patients with acromegaly and GHD use a multitude of PROMs, often poorly reported. Since a substantial proportion of studies report discrepancies between PROs and biochemical outcomes, PROMs are pivotal in the evaluation of disease activity. Therefore, harmonization of PROs in clinical practice and research by development of core outcome sets is an important unmet need.

Abstract
The effectiveness and short-term safety of recombinant human GH (r-hGH) in acromegaly patients with GH deficiency (GHD) after treatment are not well established. The study includes ten subjects with acromegaly who had GHD treated with r-hGH for 6 months. Control groups consisted of ten age-, gender-, and BMI-matched healthy subjects and ten active acromegaly patients who were treatment naïve. Body composition, quality of life (QoL), muscle strength, lipid profile, and cardiovascular risk factors were assessed in all subjects at baseline, and the same parameters were reassessed after 6 months of therapy with r-hGH in acromegaly with GHD. Repeat magnetic resonance imaging of the sella was performed in treated subjects. Optical colonoscopy was done and biopsies were taken from multiple sites for proliferation indices (Ki67). The median duration of GHD was 17.8 months and dose of r-hGH administered was 5.7±1.5 μg/kg per day. There was improvement in bone mineral content (P=0.01), bone mineral density (P=0.04), muscle strength (P<0.001), total cholesterol (P=0.003), high-density cholesterol (P<0.001), and QoL - score (P=0.005), and reduction in low-density cholesterol (P=0.003) and triglyceride (P=0.004) after treatment. There was no change in lean body mass, total body fat, hsCRP, lipoprotein (a), and fibrinogen levels. There was a modest increase in plasminogen activator inhibitor 1 (P=0.002), but it was lower compared with healthy controls and treatment naïve acromegalics (P=0.007). Six month-r-hGH therapy improves body composition, atherogenic lipid profile, QoL, and muscle strength in GHD patients who had acromegaly. Long-term prospective studies are needed to evaluate the effect of r-hGH therapy in these patients.

Abstract
Background Adult Growth Hormone Deficiency (AGHD) is a debilitating condition resulting from tumors, pituitary surgery, radiation of the head, head injury, or hypothalamic-pituitary disease. This qualitative study was conducted to better understand the multi-faceted impacts and treatment effects of GHD on adult patients’ daily lives. Seven focus groups and four telephone interviews were conducted in three countries. Eligible AGHD patients were age 22 or older who had started and stopped growth hormone treatment at least once as an adult. Transcripts were analyzed thematically. Results Thirty-nine patients were interviewed; majority etiology was pituitary disease or tumor (62%). Thirty-four patients (87%) were currently on growth hormone replacement therapy; therapy initiation mean age was 43 years. Analysis identified five domains of disease impact: 1) Psychological Health - changed body or self-image and negative emotional impacts; 2) Physical Health - problems with sleep/fatigue, sex drive, weight gain, hair, skin, muscle/bone loss; 3) Cognition - concentration or memory trouble; 4) Energy Loss and its negative impacts (productivity, exercise, chores, socialization, or motivation); and 5) Treatment Effect - treatment enhances quality of life, enabling patients to increase effort (exercise, chores, or work improvements). Energy and sleep are improved. Saturation of themes was reached after the sixth focus group. A conceptual model of GHD disease impacts was developed. Conclusions Untreated AGHD has significant negative impacts for patients, which treatment often improves. It is important for clinicians and researchers to understand these multiple impacts so that they can address them in individualized treatment plans and incorporate them when assessing treatment outcomes.

Abstract
CONTEXT Approximately 50 000 adults in the United States are diagnosed with GH deficiency, which has negative impacts on cognitive functioning, psychological well-being, and quality of life. OBJECTIVE This paper presents development and validation of a patient-reported outcome measure (PRO), the Treatment-Related Impact Measure-Adult Growth Hormone Deficiency (TRIM-AGHD). The TRIM-AGHD was developed to measure the impact of GH deficiency and its treatment. DESIGN AND SETTINGS The development and validation of the TRIM-AGHD was conducted according to the Food and Drug Administration guidance on the development of PROs. Concept elicitation, conducted in three countries included interviews with patients, clinical experts, and literature review. Qualitative data were analyzed based on grounded theory principles, and draft items were cognitively debriefed. The measure underwent psychometric validation in a US clinic-based population. An a priori statistical analysis plan included assessment of the measurement model, reliability, and validity. Item functioning was reviewed using item response theory analyses. PATIENTS OR OTHER PARTICIPANTS Forty-eight patients and six clinical experts participated in concept elicitation and 169 patients completed the validation study. MAIN OUTCOME MEASURE TRIM-AGHD was measured. RESULTS Factor analysis resulted in four domains: energy level, physical health, emotional health, and cognitive ability. The item response theory confirmed adequate item fit and placement within their domain. Internal consistency ranged from 0.82 to 0.95 and test-retest ranged from 0.80 to 0.92. All prespecified hypotheses for convergent validity and all but two for discriminant validity were met. CONCLUSIONS The final 26-item TRIM-AGHD can be considered a reliable and valid PRO of the impact of disease and treatment for adult GH deficiency.

Abstract
This large-scale observational study examined the long-term effectiveness and safety of growth hormone (GH) replacement therapy for adult GH deficiency (GHD) in Japanese clinical practice using the Hypopituitary Control and Complications Study database. The study included 402 GHD patients for safety analyses and a subset of 209 patients (149 adult-onset and 60 childhood-onset GHD patients) who had not previously received GH replacement therapy for the efficacy analyses. Data on clinical, metabolic, quality of life (QoL) characteristics, and all adverse events (AEs) were collected at baseline (start of GH treatment), 6 months, 1 year and 2 years. Over the observation period, there were improvements from baseline in insulin-like growth factor-I standard deviation scores (P<0.001), although the changes in metabolic parameters were minimal. QoL (Short Form-36) Z-scores significantly increased from baseline in both onset-type groups for several subscale domains (P<0.05). A total of 145 (36.1%) patients experienced ≥1 AE. Common AEs were hyperlipidaemia (2.7%) and hyperinsulinaemia (2.2%). Some patients experienced recurrent hypothalamic/pituitary tumour (events per 1000 patient-years: 2.78), new benign (0.93), malignant tumour (10.28) or other new tumour (0.93), new diabetes mellitus (7.45), and new stroke (3.71). Seven patients died during the observation period. Our safety findings are inconclusive about the associations between GH replacement and AEs, although the incidence of diabetes mellitus and cardiovascular events are similar to those reported in the Japanese general population. In conclusion, the key beneficial effects of GH replacement therapy for GHD are observed in routine clinical practice in Japan.

Abstract
OBJECTIVE To summarise the evidence about the efficacy and safety of using GH in adults with GH deficiency focusing on quality of life and body composition. DATA SOURCES We searched MEDLINE, EMBASE, Cochrane CENTRAL, Web of Science and Scopus through April 2011. We also reviewed reference lists and contacted experts to identify candidate studies. STUDY SELECTION Reviewers, working independently and in duplicate, selected randomised controlled trials (RCTs) that compared GH to placebo. DATA SYNTHESIS We pooled the relative risk (RR) and weighted mean difference (WMD) by the random effects model and assessed heterogeneity using the I(2) statistic. RESULTS Fifty-four RCTs were included enrolling over 3400 patients. The quality of the included trials was fair. GH use was associated with statistically significant reduction in weight (WMD, 95% confidence interval (95% CI): -2.31 kg, -2.66 and -1.96) and body fat content (WMD, 95% CI: -2.56 kg, -2.97 and -2.16); increase in lean body mass (WMD, 95% CI: 1.38, 1.10 and 1.65), the risk of oedema (RR, 95% CI: 6.07, 4.34 and 8.48) and joint stiffness (RR, 95% CI: 4.17, 1.4 and 12.38); without significant changes in body mass index, bone mineral density or other adverse effects. Quality of life measures improved in 11 of the 16 trials although meta-analysis was not feasible. RESULTS GH therapy in adults with confirmed GH deficiency reduces weight and body fat, increases lean body mass and increases oedema and joint stiffness. Most trials demonstrated improvement in quality of life measures.

Abstract
Impaired quality of life (QoL) is commonly described as being associated with growth hormone (GH) deficiency (GHD), and beneficial effects of GH replacement therapy on QoL have been reported. However, most studies examined heterogeneous cohorts of patients GHD of varying etiologies, severities and age of onset. Most of these patients miss other pituitary hormones, whose replacement can also influence QoL. We studied the QoL of a homogeneous cohort of 20 adults with isolated GH deficiency (IGHD) due to the same mutation in the GH-releasing hormone receptor gene (IGHD, 10 men) using the Life Satisfaction Hypopituitarism Module (QLS-H), and compared them with 20 matched controls residing in the same community (CO, 10 men). Additionally, the IGHD group was evaluated after 6 months of treatment with bi-monthly depot GH, and after 12 months from its interruption. There was no difference in the total score of QoL (TSQoL) or in any of the nine categories that composes the questionnaire between IGHD and CO. Similar results were obtained when data were analyzed by sex. GH treatment only increased satisfaction with physical endurance, but did not cause an increase in the TSQoL. We conclude that in this unique population congenital, untreated, lifetime IGHD does not reduce QoL, and treatment with GH for 6 months only causes improvement in satisfaction with physical resistance.

Abstract
The present studies were conducted to determine if increasing central levels of the neurotrophic factor insulin-like growth factor-1 (IGF-I) either directly or indirectly produces anxiolytic and antidepressant-like effects in the mouse. Central levels of IGF-I can be increased directly, by administering IGF-I, or indirectly by blocking the insulin-like growth factor binding proteins (IGFBPs). The IGFBP family has the unique ability to regulate IGF-I levels by sequestering IGF-I into an inactive complex. Therefore, an IGFBP inhibitor increases the level of IGF-I available to bind to its receptor. Intracerebroventricular (icv) administration of the nonspecific IGFBP inhibitor NBI-31772 (10-30 microg) increases the number of punished crossings in the four-plate test and NBI-31772 (0.3-10 microg) increases time spent in the open quadrant of the elevated zero maze (EZM), indicative of anxiolytic-like effects. NBI-31772 (3-30 microg) also decreases immobility time in the tail suspension test, indicative of antidepressant-like effects. Similarly, icv administration of IGF-I (0.1 microg) produces anxiolytic-like effects in the four-plate test and IGF-1 (0.3-1 microg) produces anxiolytic-like effects in the EZM. IGF-I (10 microg) also produces antidepressant-like effects in the tail suspension test. Coadministration of the IGF-I receptor antagonist JB1 with NBI-31772 or IGF-I blocks the anxiolytic-like and antidepressant-like effects of these compounds. These results suggest that NBI-31772 produces behavioral effects by increasing levels of IGF-I that in turn activate the IGF-I receptor. The present studies demonstrate that an IGFBP inhibitor mimics the behavioral effects of IGF-I and that IGFBP inhibition may represent a novel mechanism by which to increase IGF-I to treat depression and anxiety.

Abstract
OBJECTIVE To evaluate validity and reliability of the Japanese version of the Quality of Life-Assessment of Growth Hormone Deficiency in Adults (QoL-AGHDA). DESIGN Observational study; cross-sectional, longitudinal. METHODS Seventy-five adults with growth hormone deficiency completed the SF-36 (a generic health-related QOL scale) and the QoL-AGHDA before growth hormone replacement therapy and approximately 3 weeks later (when the therapy began). A sample (n=1000) of controls from the general population was also studied. We computed rates of missing data, measured reproducibility and internal consistency reliability, and tested for known-groups validity, concurrent validity, unidimensionality (by principle component analysis), and content validity. RESULTS Rates of missing data were low (0-1.4%). The mean of QoL-AGHDA scores in the patients was 8.2 (SD, 6.4). The scores were reproducible (k=0.41-0.78), and internally consistent (alpha=0.91) and the scale was unidimensional. QoL-AGHDA scores were associated with SF-36 scores as hypothesized. Scores were significantly higher in the patients than in controls (8.1+/-0.7, and 5.6+/-0.2, P<0.001). Discrimination between patients and controls was slightly better using scores on the "General Health" and "Role Physical" subscale of the SF-36 as explanatory variables than using QoL-AGHDA scores. CONCLUSIONS The QoL-AGHDA's reliability, validity, and rates of missing data were satisfactory, and the scale was confirmed to be unidimensional. However, because some subscales of the SF-36 were better for discriminating patients from controls, the content validity of the QoL-AGHDA may need to be re-evaluated.

Abstract
OBJECTIVES The objectives were (1) to report the preliminary development of the Hormone Deficiency-dependent Quality of Life (HDQoL) questionnaire, a new individualized questionnaire in which respondents rate personally applicable domains for importance and impact of hormonal deficiency and its treatment; (2) to evaluate the HDQoL's psychometric properties for adults with hypopituitarism including growth hormone deficiency (GHD). METHODS Internal consistency reliability, aspects of validity, and sensitivity to change of the HDQoL were investigated in: (1) a cross-sectional survey of 157 adults with treated or untreated GHD; (2) a randomized, placebo-controlled study of 3 months' growth hormone (GH) withdrawal from 12 of 21 GH-treated adults. RESULTS Thirteen of the original 18 HDQoL domains were relevant and important for GH-deficient adults. The shorter 13-item HDQoL had excellent internal reliability (Cronbach's alpha coefficient = 0.914, n = 109), and was sensitive to sex differences (cross-sectional study): women perceived worse present QoL than men [t(149.8) = 2.33, P = 0.021]. The HDQoL was sensitive to change (GH-withdrawal study) with a significant between-group difference in change in domain scores for things I can do physically[t(16) = 2.47, P = 0.025, 2-tailed], patients withdrawn from GH reporting greater negative impact of hormone deficiency on this domain at end-point. Qualitative work resulted in the addition of seven new HDQoL domains, including energy and bodily pain. CONCLUSION The HDQoL, although at an early stage of development, proved useful in identifying expected changes following GH withdrawal. The extended 20-item version is recommended for further evaluation in assessing the impact of hypopituitarism on QoL.

Abstract
The availability of recombinant human GH and somatostatin analogs has resulted in widespread treatment for adults with GH deficiency (GHD) and those with GH excess (acromegaly). Despite being at opposite ends of the spectrum in terms of their GH/IGF-I axis, both of these populations experience overlapping somatic impairments. Adults with untreated GHD have low circulating levels of IGF-I that manifest as altered body composition with increased fat and reduced lean body and skeletal muscle mass. At the other end of the spectrum, adults with GH excess, who have elevated levels of IGF-I, also have altered body composition. Impairments that result from disorders of either GHD or GH excess are both associated with increased functional limitations, such as reduced ability to walk quickly for prolonged periods, and poorer health-related quality of life (HR-QoL). Adults with untreated GHD and GH excess both commonly complain of excessive fatigue that seems to be associated more with impaired aerobic than muscular performance. Several studies have documented that administration of GH or somatostatin analogs to adults with GHD or GH excess, respectively, ameliorates abnormal biochemical profile and the associated somatic impairments. However, whether these improvements translate into improved physical function in adults with GHD or GH excess remains largely unknown, and their impact on HR-QoL controversial. Review of placebo-controlled trials to date suggests that GH and somatostatin analogs have greater effects on gas exchange and aerobic performance than as anabolic agents on skeletal muscle mass and function. Future investigations should include dose-response studies to establish the optimal combination of pharmacological agents plus exercise required to improve not only biochemical markers but also physical function and HR-QoL in adults with GHD or GH excess.

Abstract
Background Psychometric properties of two measures of psychological well-being were evaluated for adults with growth hormone deficiency (GHD): the General Well-being Index, (GWBI) – British version of the Psychological General Well-being Index, and the 12-item Well-being Questionnaire (W-BQ12). Methods Reliability, structure and other aspects of validity were investigated in a cross-sectional study of 157 adults with treated or untreated GHD, and sensitivity to change in a randomised placebo-controlled study of three months' growth hormone (GH) withdrawal from 12 of 21 GH-treated adults. Results Very high completion rates were evidence that both questionnaires were acceptable to respondents. Factor analyses did not indicate the existence of useful GWBI subscales, but confirmed the validity of calculating a GWBI Total score. However, very high internal consistency reliability (Cronbach's alpha = 0.96, N = 152), probably indicated some item redundancy in the 22-item GWBI. On the other hand, factor analyses confirmed the validity of the three W-BQ12 subscales of Negative Well-being, Energy, and Positive Well-being, each having excellent internal reliability (alphas of 0.86, 0.86 and 0.88, respectively, N from 152 to 154). There was no sign of item redundancy in the highly acceptable Cronbach's alpha of 0.93 (N = 148) for the whole W-BQ12 scale. Whilst neither questionnaire found significant differences between GH-treated and non-GH-treated patients, there were correlations (for GH-treated patients) with duration of GH treatment for GWBI Total (r = -0.36, p = 0.001, N = 85), W-BQ12 Total (r = 0.35, p = 0.001, N = 88) and for all W-BQ12 subscales: thus the longer the duration of GH treatment (ranging from 0.5 to 10 years), the better the well-being. Both questionnaires found that men had significantly better overall well-being than women. The W-BQ12 was more sensitive to change than the GWBI in the GH-Withdrawal study. A significant between-group difference in change in W-BQ12 Energy scores was found [t(18) = 3.25, p = 0.004, 2-tailed]: patients withdrawn from GH had reduced energy at end-point. The GWBI found no significant change. Conclusion The W-BQ12 is recommended in preference to the GWBI to measure well-being in adult GHD: it is considerably shorter, has three useful subscales, and has greater sensitivity to change.

Abstract
Além de influenciar o crescimento corpóreo, o hormônio do crescimento, ou somatotrófico, desempenha importante papel no metabolismo, composição corporal, perfil lipídico, estado cardiovascular e longevidade. Seu controle é multi-regulado por hormônios, metabólitos e peptídeos hipotalâmicos. Dados sobre a Deficiência Isolada de GH (DIGH) obtidos a partir da descrição da mutação IVS1+1G®A no gene do receptor do hormônio liberador do GH (GHRH-R) em indivíduos da cidade de Itabaianinha, SE, são revisados. São abordadas novas perspectivas sobre o modelo de resistência ao GHRH, a importância do GHRH no controle da secreção de GH, a freqüência das mutações do gene do GHRH-R, a relevância diagnóstica do IGF-I e os achados metabólicos, cardiovasculares e de qualidade de vida nestes indivíduos.

Abstract
The present review attempts to reconcile the dichotomy that exists in the literature in relation to fibromyalgia, in that it is considered either a somatic response to psychological stress or a distinct organically based syndrome. Specifically, the hypothesis explored is that the link between chronic stress and the subsequent development of fibromyalgia can be explained by one or more abnormalities in neuroendocrine function. There are several such abnormalities recognised that both occur as a result of chronic stress and are observed in fibromyalgia. Whether such abnormalities have an aetiologic role remains uncertain but should be testable by well-designed prospective studies.

Abstract
To develop reference ranges for the Questions on Life Satisfaction Hypopituitarism Module (QLS-H), a new quality of life questionnaire for patients with hypopituitarism, data from 8177 adults were collected in France, Germany, Italy, The Netherlands, Spain, the United Kingdom, and the United States QLS-H scores declined with age, were lower in females than males, and differed significantly among countries. From these reference ranges we derived equations for z-scores, which adjust for age, gender, and country. QLS-H results from 957 adults with GH deficiency (GHD) participating in clinical trials were analyzed. At baseline, QLS-H scores were lower in females and differed significantly among countries. QLS-H scores significantly increased after GH treatment (6-8 months), but differences by country persisted. Calculating z-scores for patients eliminated all gender and most country differences. Pooled z-scores (mean +/- SD) from all patients increased from -0.99 +/- 1.39 at baseline to -0.14 +/- 1.30 after GH treatment. Quality of life assessment in adults with GHD requires the use of z-scores to correct for age, gender, and country differences. This approach allows pooling of data from different cohorts and comparison with general populations. QLS-H scores in adults with GHD were significantly decreased at baseline and were almost normalized after 6-8 months of GH therapy.

Abstract
OBJECTIVE There are few studies of quality of life (QOL) in adults with growth hormone deficiency (GHD) compared to matched control populations without GHD. These have shown impairments in a variety of QOL measures, which improve but do not normalize after short-term replacement with GH. There is little information on QOL in long-term treated GHD patients compared with controls without GHD. PATIENTS AND METHODS A total of 120 adults with GHD who had received GH replacement for at least 1 year were identified from the neuroendocrine clinic. Patients were asked to complete eight QOL questionnaires and an Energy Visual Analogue Scale (VAS). Results were compared with 83 control subjects without GHD from the local population who agreed to complete seven of the QOL questionnaires (excluding Disease Impact scale) and the energy VAS. The eight questionnaires were a combination of generic and disease-specific questionnaires used to assess health related QOL, namely: Short Form-36 (SF-36), Nottingham Health Profile (NHP), Disease Impact, Life Fulfilment and Satisfaction scales, Mental Fatigue Questionnaire (MFQ) and Self Esteem scale, Hospital Anxiety Depression (HAD) scale and QOL-AGHDA (assessment of GHD in adults). RESULTS Eighty-nine patients returned questionnaires and 85 (71%) had complete data for analysis. The mean (SD) duration of GH replacement was 36.0 +/- 26.4 (range 13-159) months. Mean age was 43.9 +/- 15.8 years (37 males) in treated GHD patients compared to a mean age 41.7 +/- 10.5 years (32 males) in the controls. Mean IGF-1 levels were 22.5 +/- 13.6 nmol/l in the GHD patients and the mean dose of GH replacement was 1.2 +/- 0.4 IU daily. Analysis of the QOL questionnaires from the GH treated patients revealed highly significant impairments in all measures (most P </= 0.0001, except life fulfilment-material, P = 0.33) compared to the control population. CONCLUSIONS This large population with treated GH deficiency have significant impairments in multiple aspects of QOL despite replacement with GH and other pituitary hormones for at least 1 year (mean 3 years). It is likely therefore that other factors in addition to GH deficiency must influence QOL in these patients. Further strategies to improve QOL in these individuals should therefore be considered, e.g. psychological support and treatments and physical treatments (such as exercise programmes).

Abstract
OBJECTIVE To evaluate the psychometric properties of two health status measures for adults with growth hormone deficiency (GHD): Nottingham Health Profile (NHP) and Short-Form Health Survey (SF-36). DESIGN (1) A cross-sectional survey of adults with treated or untreated GHD to assess reliability and validity of the questionnaires. (2) A randomized, placebo-controlled study of 3 months' GH withdrawal from GH-treated adults to assess the sensitivity of the questionnaires to change. PATIENTS (1) A cross-sectional survey of 157 patients with severe GHD (peak GH < 10 mU/l on provocative testing), mean age 48.9 years (range 23-70 years), who had either received GH replacement therapy for at least 6 months immediately prior to the study or had not received GH treatment in the previous 6 months. (2) GH treatment was withdrawn from 12 of 21 GH-treated adults, all with severe GHD (peak GH < 7.7 mU/l on provocative testing), mean age 44.9 years (range 25-68 years). MEASUREMENTS The NHP and SF-36 were used once in the cross-sectional survey, but twice in the GH-withdrawal study, at baseline and end-point (after 3 months). RESULTS (1) Cross-sectional survey. Both questionnaires had high internal consistency reliability with subscale Cronbach's alphas of > 0.73 (NHP) and > 0.78 (SF-36). Calculation of an NHP Total Score, occasionally reported in the literature, was shown to be inadvisable. Overall, patients with GHD were found to have significantly worse perceived functioning than the UK general population in SF-36 subscales of General Health, Bodily Pain, Social Functioning, Physical Functioning, Role-Emotional, Role-Physical, and Vitality. Although neither questionnaire found significant differences between GH-treated and non-GH-treated patients, there were correlations with duration of GH treatment (P < 0.01) for GH-treated patients in SF-36 Mental Health (r = 0.29, N = 87) and SF-36 Vitality (r = 0.33, N = 88), indicating improvement with increasing treatment duration. The SF-36 was also more sensitive than the NHP to sex differences: men had significantly better health status compared with women (P < 0.05) in all SF-36 subscales but Mental Health, but only in one NHP subscale (Physical Mobility). (2) GH-withdrawal study. Significant between-group differences in change were found in SF-36 General Health [t(17) = 2.76, P = 0.013, two-tailed] and SF-36 Mental Health [t(17) = 2.41, P = 0.027, two-tailed]: patients withdrawn from GH reported reduced general health and mental health at end-point. The NHP found no significant change. CONCLUSIONS The SF-36 is a better measure than the NHP of health status of people with GH deficiency because of its greater discriminatory power, with ability to detect lesser degrees of disability. It also has superior sensitivity to some subgroup differences and superior sensitivity to change compared with the NHP. The SF-36 is highly acceptable to respondents, and has very good internal consistency reliability. The SF-36 is recommended to measure the health status of adults with GH deficiency.

Abstract
OBJECTIVE The purpose of this pilot study was to determine the effect of a 1.5-day multidisciplinary fibromyalgia treatment program on impact of illness, depression, and life fulfillment. DESIGN A sample of 100 consecutive enrollees in a 1.5-day multidisciplinary group outpatient fibromyalgia treatment program between February 14, 2000, and May 9, 2000, in a tertiary medical center was used for this study. The Fibromyalgia Impact Questionnaire, the Life Fulfillment and Satisfaction Scales, and the Center for Epidemiologic Studies Depression Scale were administered to subjects immediately preceding the treatment program and by mail 1 mo after completing the program. RESULTS The 78 subjects who returned their surveys 1 mo after treatment demonstrated significant improvement in the area of the impact of illness as measured by the Fibromyalgia Impact Questionnaire total score (51.3-44.7, P < 0.002). There was no significant improvement in depressive symptoms (P < 0.056) or the level of life fulfillment (P < 0.53). Subjects with depression improved on the Fibromyalgia Impact Questionnaire to the same degree as those without depression. The 22 nonresponders did not differ significantly from the responders in the variables of sex, age, pretreatment Fibromyalgia Impact Questionnaire score, marital status, educational level, family income, duration of symptoms, or history of depression. CONCLUSIONS These results suggest that a 1.5-day multidisciplinary fibromyalgia treatment program does have a significant positive effect on the impact of illness among patients with fibromyalgia with or without concomitant depression and may be a cost-effective model for the treatment of these patients.

Abstract
BACKGROUND Quality of life (QoL) is reduced in GH-deficient adults compared with the normal population. Further support for the role of GH in the maintenance of QoL is derived from short-term studies of GH replacement in severely GH-deficient adults; these have predominantly reported beneficial effects, although the degree of improvement has often been modest. To date, however, there are few data to demonstrate whether this beneficial effect on QoL is maintained in the long term. PATIENTS AND METHODS This study consisted of the follow-up of 85 GH-deficient adults who completed the Nottingham Health Profile (NHP) and the Psychological General Well-Being Schedule (PGWB) self-rating questionnaires in 1992, as part of a 12-month double-blind randomized study of GH replacement. In 2001 we attempted to contact all 85 patients and asked them to complete the two questionnaires again. Follow-up data were obtained in 61 patients. The findings were analysed according to whether the individual had received GH continuously since completion of the initial study, received no further GH replacement, or received GH replacement for only part of the intervening time. Both the NHP and the PGWB give a total score and subsection scores for six specific areas of QoL. A high score correlates with increased morbidity in the NHP, and with reduced morbidity in the PGWB. RESULTS Fifty-nine patients completed the NHP at both time points. The patients who continued GH (n = 17) had significantly greater morbidity at baseline than patients who opted to discontinue therapy (n = 27), as reflected by the higher scores overall (5.7 +/- 4.0 vs. 2.8 +/- 3.5; P = 0.01) and in the energy subsection (47.0 +/- 34.7 vs. 13.2 +/- 28.6; P < 0.001). Over the study period energy levels improved in the patients who remained on GH therapy (47.0 +/- 34.7 vs. 25.7 +/- 31.0; P = 0.04). By contrast, a deterioration in the physical mobility subsection (2.4 +/- 5.4 vs. 8.2 +/- 16.7; P = 0.04) occurred in the patients who did not continue GH therapy, and no change occurred in the energy subsection. In the 36 patients who completed the PGWB significant differences were observed at baseline between patients who received GH replacement continuously (n = 10) and those who discontinued therapy (n = 21) in the overall score (67.2 +/- 14.1 vs. 86.8 +/- 14.7; P = 0.001); and in the subsections for anxiety (P = 0.04), depression (P = 0.04), well-being (P = 0.001), self-control (P = 0.04) and vitality (P < 0.001); the greater morbidity at baseline being observed in the patients who continued GH replacement. In the patients receiving GH continuously for 9 years the vitality subsection score improved significantly (7.7 +/- 2.4 vs. 12.5 +/- 3.2; P = 0.003), whereas no change in vitality score occurred in patients who did not continue GH therapy. The change in the energy subsection of the NHP and vitality subsection of the PGWB over the 9 years of the study were significantly different between the patients who opted to continue GH replacement and those who discontinued therapy (P = 0.008 and P < 0.001, respectively). CONCLUSION During this 9-year study, small but significant declines in health were observed in GH-deficient adults who remained untreated. By contrast, the patients who received GH continuously experienced improvements in energy levels while all other areas of QoL were maintained. The beneficial effects of GH on QoL are therefore maintained with long-term GH replacement and obviate the reduction in QoL seen over time in untreated GH-deficient adults.

Abstract
Adult growth hormone (GH) deficiency is a well-described clinical syndrome with many features reminiscent of fibromyalgia. There is evidence that GH deficiency as defined in terms of a low insulin-like growth factor-1 (IGF-1) level occurs in approximately 30% of patients with fibromyalgia and is probably the cause of some morbidity. It seems most likely that impaired GH secretion in fibromyalgia is related to a physiologic dysregulation of the hypothalamic-pituitary-adrenal axis (HPA) with a resulting increase in hypothalamic somatostatin tone. It is postulated that impaired GH secretion is secondary to chronic physical and psychological stressors. It appears that impaired GH secretion is more common than clinically significant GH deficiency with low IGF-1 levels. The severe GH deficiency that occurs in a subset of patients with fibromyalgia is of clinical relevance because it is a treatable disorder with demonstrated benefits to patients.

Abstract
OBJECTIVE Elderly patients with GH deficiency (GHD) have significant impairments in multiple aspects of quality of life (QOL) but similar lipid profiles compared to age-matched control subjects. There are, however, no data on changes in these parameters with time. This study assessed the impact of untreated GHD over a period of 2 years in a group of elderly patients with hypothalamic-pituitary disease in relation to new illnesses and differences in body composition, circulating lipid profile levels and QOL. Control subjects were also followed for 2 years. SUBJECTS Twenty-seven elderly patients (> 65 years) with hypothalamic-pituitary disorders and GHD (mean peak stimulated GH response 1.6 mIU/l, range 0.6--5.0) were studied initially. Two years later 21 (13 males) agreed to attend for reassessment. Mean age was then 72.7 +/- 5.04 years (range 67--85). Eighteen patients had pituitary tumours, three had craniopharyngiomas. Twenty-seven control subjects were studied at baseline and 17 (7 males) agreed to attend for reassessment. Mean age was then 75.9 +/- 6.97 years (range 67--88). METHODS Weight, body mass index (BMI), total fat mass (FM) (bioelectrical impedance), serum IGF-1 and fasting lipid profile (total cholesterol, triglyceride, HDL cholesterol, LDL cholesterol) were measured. QOL was assessed in both groups using five interviewer-administered self-rating questionnaires: the Nottingham Health Profile, Short Form-36, Hospital Anxiety and Depression Scale, Mental Fatigue Questionnaire and Life Fulfillment Scale. The GHD group also completed the Disease Impact Scale. RESULTS Two of the 27 patients with GHD died during the 2-year follow-up (myocardial infarction and probable cerebrovascular accident). Four controls could not be traced but there were no deaths in the other 23. In the 21 GHD patients after 2 years, mean serum IGF-1 and BMI were unchanged (12.6 +/- 5.8 vs. 13.3 +/- 5.1 nmol/l, P = 0.5 and 28.3 +/- 4.3 vs. 29.1 +/- 4.2, P = 0.5, respectively) at the 2-year follow-up and there were no significant changes in the lipid profiles. However, there was a significant reduction in fat mass (31.7 +/- 11.2 vs. 28.5 +/- 10.9%, P = 0.04). In the 17 control subjects after 2 years, serum IGF-1 levels (17.2 +/- 4.0 vs. 15.7 +/- 5.6 nmol/l, P = 0.4), BMI and fat mass were unchanged. However, there was a significant fall in total cholesterol levels over the 2-year follow-up (6.3 +/- 0.9 vs. 5.7 +/- 0.9 mmol/l, P < 0.0001), although LDL cholesterol, triglycerides and HDL cholesterol were unchanged. Analysing the QOL data, the GHD patients had less energy (P < 0.05), more depression (P < 0.05), more pain (P < 0.05) and lower life fulfillment scores (P < 0.01) after 2 years. However, the control subjects also had less energy (P < 0.05), less vitality (P < 0.05) and lower self-esteem (P < 0.05), more depression (P < 0.05), worse mental health (P < 0.05), life fulfillment personal (P < 0.01), life fulfillment material (P < 0.02), physical functioning and role physical functioning (P < 0.05) after 2 years. Comparing the patients and controls at baseline, there were significant differences in IGF-1, BMI, FM, LDL cholesterol, personal life fulfillment, mental fatigue, general health and mental health. However, after 2 years, only BMI and depression scores were significantly different. CONCLUSION These patients with untreated GHD did not have deterioration of body composition or lipid profiles when reassessed after a period of 2 years. In fact, fat mass fell. The control subjects did have a significant decrease in total cholesterol but no change in other lipids or body composition. Some quality of life domains did deteriorate in the patients with GHD. However, the control subjects also had worse quality of life scores after 2 years which were then little different from the GHD patients. These results raise doubts about the benefits of GH replacement in elderly people with GHD.

Abstract
OBJECTIVE In healthy adults the secretion of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) declines with ageing and body composition alters, particularly with an increase in total body fat. In elderly people, hypothalamic-pituitary disease can cause GH deficiency (GHD), compared with age matched controls. This study aimed to clarify whether GHD in the elderly is associated with differences in body composition, circulating lipid levels and quality of life (QOL) compared with control subjects. SUBJECTS Twenty-seven elderly patients (14 males, mean age 71 years, range 65-83) with hypothalamic-pituitary disorders (23 pituitary tumours) and GHD (mean (SD) peak stimulated GH response 1.6 mIU/l (1.03) range 0.6-5) were studied. Twenty-five patients had been treated surgically (six cranial surgery, 19 transsphenoidal) and eight patients had received external cranial irradiation. Twenty-seven control subjects (14 males, mean age 72 years, range 65-86) were also studied. METHODS Weight, body mass index (BMI), total fat mass (FM, bioelectrical impedance), waist to hip ratio (WHR), serum IGF-1, fasting blood glucose and lipid profile were measured. QOL was assessed in both groups using five interviewer administered self-rating questionnaires: The Nottingham Health Profile, Short-Form 36, Hospital Anxiety and Depression Scale, Mental Fatigue Questionnaire and Life Fulfilment Scale. The GHD group also completed the Disease Impact Scale. RESULTS The data (mean (SD)) from males and females were analyzed separately. The male patients had a higher BMI than controls, 28.9(4.5) vs. 25.2(2.3) kg/m2 (P = 0.01) but the BMI in the female patients and controls was similar. In the female patients compared with the controls, FM was higher 39. 4(6) vs. 33.1(8.3) % (P = 0.02), WHR was also higher 0.9(0.08) vs. 0. 83(0.09) (P = 0.03) and serum IGF-1 levels were lower 10.8(6.4) vs. 18.2(6.5) nmol/l (P = 0.01). However, in the male patients, FM, WHR and IGF-1 levels were similar to the controls. Fasting blood glucose was similar in both male and female patients and the controls. Two female patients and one male control subject were taking lipid-lowering agents and were therefore excluded from the analysis of lipid profiles. Total cholesterol, triglyceride, LDL cholesterol, HDL cholesterol and total cholesterol/HDL cholesterol ratio were not significantly different for both male and female patients compared with the controls. The 27 patients with GHD reported significantly less energy (P < 0.05), mobility (P < 0.05) and personal life fulfillment (P < 0.01) than the 27 controls. There were significantly more problems with emotional reaction (P < 0.01), social isolation (P < 0.05) and mental fatigue (P < 0.05). Additionally the GHD group reported more impairment in areas of social functioning (P < 0.05), general health (P < 0.05) and mental health (P < 0.05). The GHD group reported a modest degree of disease impact (mean score of 14.1). There were no significant differences in the domains of material life fulfillment, pain, sleep, physical functioning, vitality, anxiety, depression, self-esteem or role physical functioning compared with the controls. CONCLUSION Compared with control subjects, the elderly female patients with hypothalamic-pituitary disease and GHD had a significantly higher total fat mass, with the WHR indicating a more central fat distribution and lower female serum IGF-1 levels. In contrast, elderly male patients had similar total fat mass, WHR and IGF-1 levels compared to the controls. There were no significant differences in the lipid profiles between male or female patients compared to controls. However, many of the male patients were receiving androgen replacement which might have influenced these results. Low HDL cholesterol concentrations are probably a better predictor of future cardiovascular disease than raised LDL cholesterol levels in the elderly population and these were similar in patients and controls for both

Abstract
It is now recognized that adults with pituitary disease and growth hormone (GH) deficiency have impaired physical and psychological functioning, including decreased quality of life. Research on quality of life continues to develop with reference to this patient group. In particular, disease-specific measures of quality of life have been developed, and data on long-term follow-up are now becoming available. Although the majority of studies investigating the effects of GH replacement show that quality of life improves with treatment, the results are not consistent. The relationship between quality of life and depressed mood in GH-deficient adults is complex and needs further study.

Abstract
OBJECTIVE Growth hormone deficiency (GHD) in adults has been associated with impaired health status and quality of life (QoL) in several studies using generic measures, and in a few studies using recently developed disease-specific measures. Theoretically, disease-specific measures may be more sensitive and succinct than generic measures, and hence prove convenient for general use in clinical practice. The present study sought to validate the scaling properties of the disease-specific QoL-AGHDA measure through the implementation of Rasch analysis. The study also sought to compare, by using the QoL-AGHDA, the QoL of a relatively large Swedish cohort of adults with untreated GHD with that of a reference population also from Sweden. PATIENTS The QoL of 111 adults with untreated GHD from Stockholm and Göteborg was compared with that of 1448 adult subjects randomly selected from the population of Göteborg. MEASUREMENTS The scaling properties of the QoL-AGHDA were assessed by investigating its fit to a dichotomous Rasch model. Rasch-transformed QoL scores from the QoL-AGHDA questionnaire were stratified by age and gender, and 95% confidence intervals were calculated. RESULTS Rasch analysis of the QoL-AGHDA indicated the measure to be robust in terms of its unidimensionality and ordering properties, and lack of differential item functioning. The raw scores produced by the QoL-AGHDA are at the ordinal level. Non-overlapping 95% confidence intervals of Rasch-transformed interval scores in most age categories indicated that men and women with GHD had significantly lower QoL than the reference population. CONCLUSION The Swedish QoL-AGHDA has good scaling properties, and hence can be considered a robust measure. It is suitable for assessing quality of life in adults with GH deficiency, and for making comparisons with adults who are not growth hormone deficient. Adult GH deficiency is associated with a significant impairment in QoL.

Abstract
OBJECTIVE Studies of the effect of GH on quality of life (QOL) in growth hormone deficient (GHD) adults have reported conflicting results. Recently, however, we have demonstrated that by selecting only those patients with impaired QOL the efficacy of GH replacement on QOL can be greatly improved. The improvement in QOL was observed to correlate significantly with that recorded before commencing GH therapy. This study aims to assess if demographic variables affect QOL in untreated GHD adults or the improvement in QOL following GH therapy. DESIGN An open study of GH replacement, initiating treatment with a dose of 0.8 IU/day and titrating the dose by 0.4 IU increments to normalize the IGF-I SDS between - 2.0 and + 2.0 SD of the age related normal range. PATIENTS 65 severely GHD patients (peak GH < 9 mU/l to provocative testing), mean age 38.7 (range 17-72) years. Inclusion criterion was that of subjectively poor quality of life on clinical interview. MEASUREMENTS Blood was taken for insulin-like growth factor 1 (IGF-I). The Psychological General Well-Being Schedule (PGWB) and Adult Growth Hormone Deficiency Assessment (AGHDA) self-rating questionnaires were used to assess quality of life at baseline, three and eight months after commencing GH. RESULTS The patients were subgrouped on the basis of gender, age of onset of GHD, pathology and presence of additional pituitary hormone deficits. The cohort consisted of 40 females and 25 males, 45 of adult-onset (AO) and 20 of childhood-onset (CO). GH deficiency resulted from a hypothalamo-pituitary pathology, or treatment thereof, in 36 patients and as a result of cranial irradiation for a primary brain tumour or prophylaxis in acute lymphoblastic leukaemia in 29 patients. Isolated GH deficiency (IGHD) was present in 25 patients, and 32 patients were demonstrated to have at least two additional pituitary hormone deficits (MPHD). No significant difference was detected between baseline PGWB scores of the subgroups. Multiple linear regression analysis revealed the age of onset of GHD to be a significant determinant of both the baseline PGWB (P = 0.05) and AGHDA (P = 0.025) scores, AO patients perceiving the greater distress. A significant improvement, from baseline, in both QOL scores was observed in all subgroups at three months, and in all subgroups at eight months except IGHD, where a trend towards improvement in the AGHDA score was observed but failed to reach significance. The mean improvement in the PGWB following GH therapy was not significantly different between subgroups. Multiple linear regression analysis confirmed baseline PGWB and AGHDA scores to be the most important variable in prediction of the level of improvement in respective scores following GH therapy. Age of onset was also observed to be a significant determinant of the PGWB scores following GH therapy (P = 0.02), the CO cohort experiencing the greater improvement. A similar relationship between age of onset and AGHDA scores was not observed (P = 0.22). CONCLUSIONS Baseline QOL as assessed by self-rating questionnaires is influenced by the age of onset of the GH deficiency, adult onset patients expressing the greater distress. Improvements in QOL scores are influenced by both baseline score and to a lesser extent the age of onset of GHD, the greater improvement being observed in childhood onset patients. The degree of improvement was observed to be independent of gender, pathology and number of pituitary hormone deficits. In a cohort selected by subjectively impaired QOL, we have demonstrated childhood onset GHD patients perceive themselves to have less impairment of QOL pretreatment. In contrast to previous data in unselected cohorts, however, we have shown that those childhood onset GHD patients in whom QOL is significantly reduced, show a capacity for improvement that is equal to, if not greater, than that seen in adult onset-GHD patients.

Abstract
OBJECTIVE Adults with GH deficiency (GHD) frequently report a poor quality of life (QOL). Whether this poor QOL is specifically due to hormone deficiency or a non specific effect of a chronic condition is not known. We therefore assessed QOL in adults with hypopituitarism and GHD and compared scores with a group of patients with diabetes mellitus, another life-long condition with potentially serious complications and a group of healthy controls. PATIENTS We studied 57 patients with hypopituitarism and GHD (peak stimulated GH response < 9 mU/l) (23 male, mean age 36.4 years, mean stimulated GH response 2.3 mU/l), secondary to a variety of hypothalamic-pituitary disorders. Fifty had been treated surgically (39 cranial surgery, 11 transsphenoidal) and 37 had received external cranial irradiation involving the hypothalamic region. Fifty-seven age and sex matched patients with diabetes mellitus (31 insulin treated, 18 on oral hypoglycaemic agents, 8 on diet alone) and 57 matched healthy controls were also studied. DESIGN AND MEASUREMENTS We assessed and compared health related QOL in the 3 groups using 4 self rating questionnaires: Hospital Anxiety and Depression Scale, Self Esteem Scale, Mental Fatigue Questionnaire and Life Fulfilment Scale. In addition the GHD and diabetic groups also completed the Disease Impact Scale. RESULTS The GHD group reported significantly more depression (P < 0.05) and mental fatigue (P < 0.05) and significantly less self esteem (P < 0.05) and life fulfilment (P < 0. 05) than either the group with diabetes or the controls. Patients with GHD reported significantly higher anxiety scores (P < 0.05) than the controls. Within the GHD group there were no differences in QOL scores between patients with pituitary tumours (n = 24), craniopharyngiomas/hypothalamic tumours (n = 18) or other brain tumours. In addition there were no significant differences according to surgical treatment modality or radiotherapy. However subgroup analysis revealed that the patients who had undergone transsphenoidal surgery (n = 11) differed significantly from the control group in life fulfillment and depression (P < 0.01) only and did not differ from the DM group in any of the questionnaires used. There were no significant differences between the group with diabetes and the control group in any of the measures except depression (P < 0.05). CONCLUSIONS This study revealed a significant impairment of QOL in adults with GHD, particularly those who had undergone cranial surgery, when compared to matched patients with diabetes and healthy controls.

Abstract
Chronic pain often differs from acute pain. The correlation between tissue pathology and the perceived severity of the chronic pain experience is poor or even absent. Furthermore, the sharp spatial localization of acute pain is not a feature of chronic pain; chronic pain is more diffuse and often spreads to areas beyond the original site. Of importance, chronic pain seldom responds to the therapeutic measures that are successful in treating acute pain. Physicians who are unaware of these differences may label the patient with chronic pain as being neurotic or even a malingerer. During the past decade, an exponential growth has occurred in the scientific underpinnings of chronic pain states. In particular, the concept of nonnociceptive pain has been refined at a physiologic, structural, and molecular level. This review focuses on this new body of knowledge, with particular reference to the chronic pain state termed "fibromyalgia."

Abstract
OBJECTIVE The aim of the study was to evaluate the impact on health-related quality of life (HRQoL) in untreated GHD patients using the disease-specific Assessment of Growth Hormone Deficiency in Adults (AGHDA) questionnaire. DESIGN AND PATIENTS A cohort of 356 consecutive adult GHD patients, diagnosed after the age of 18 years, from the endocrinology units of 37 Spanish hospitals were included over a 6-month period in a longitudinal observational quality-of-life study. In addition, patients' HRQoL scores were compared to those obtained from a random sample of 963 subjects from the general population recruited by trained interviewers in a 6-month period and matched by age and sex to figures of the 1991 Spanish census. MEASUREMENTS Patients were evaluated at baseline and after 12-months. Socio-demographic and health variables such as age, sex, level of education, income level, number of chronic diseases and self-reported health status were recorded at baseline and follow-up visits. Patients underwent physical and analytical examination and completed the AGHDA questionnaire. A survey including socio-demographic, self-reported health status and the AGHDA questionnaire was administered at the individuals' homes. RESULTS Mean score for patients at baseline was 9.4 (CI = 8.4-10.4) and at 12 months 10 (CI = 8.8-11). HRQoL was worse in the case of older patients with a low level of education, lower income levels, reporting having an associated chronic disease and poor self-reported health status (P < 0.01). Untreated GHD patients maintain or slightly worsen their HRQoL after 12 months of follow-up, with high individual variability. Although AGHDA scores worsened during the observation period, differences were not statistically significant. AGHDA mean score in controls was 5.49 (CI = 5.27-5.71). Comparison of the mean AGHDA scores between patients and controls previously standardized by level of education and age were statistically different (P < 0.01), indicating that patients declared a worse HRQoL than the general population except for those aged 60-69 years. GHD patients presented a deterioration in HRQoL almost double that of the general population. CONCLUSIONS These results permit comparison of patients' scores against reference scores with regard to the desirable effect of treatment. Future use of the AGHDA questionnaire in clinical trials should try to establish a relationship between biological and HRQoL changes.

Abstract
OBJECTIVE To study the effects of human growth hormone (hGH) replacement on serum lipids and lipoprotein (a) (Lp(a)) concentrations. DESIGN A randomized double blind placebo controlled trial for 6 months followed by an open trial where all patients were treated with hGH for a further 6 months. Treatment was with recombinant hGH given in a dose of 0.125U/kg/wk increasing to 0.25U/Kg/wk. PATIENTS Thirty two patients with growth hormone deficiency were recruited, but two withdrew because of side effects. Of the thirty patients (age 35.1 +/- 11.8 year; mean +/- SD) completing the study 13 of were assigned to the placebo group for six months and 17 to active treatment from the start. MEASUREMENTS Fasting serum samples were analysed for total cholesterol, High density lipoprotein (HDL)-cholesterol, HDL-subfractions, triglycerides, lipoprotein (a) (Lp(a)) and IGF-1. LDL-cholesterol was calculated using the Friedewald formula. RESULTS Compared to placebo, 6 months treatment with hGH therapy resulted in increased IGF-1 (37.6 +/- 4.1 vs. 14.0 +/- 2.2 nmol/l, P < 0.01), but there was no significant difference in any of the lipid parameters measured between placebo and active treatment groups at 6 months. hGH was associated with a decrease in HDL-cholesterol concentration from baseline to 6 months (0.97 +/- 0.08 to 0.76 +/- 0.10 mmol/l P < 0.01), especially within the HDL2 subfraction. This reduction was maintained at 12 months. There was no change in Lp(a) concentrations from 0 to 6 months (placebo -26 (-340 to 82), median and range, active -4 (-586 to 212) mg/l). There was no change in total cholesterol, LDL-cholesterol, triglycerides or proportion of HDL subfractions. CONCLUSIONS Treatment with hGH can reduce serum HDL-cholesterol concentrations. Further investigation of this is required.

Abstract
The majority of studies (but not all) have demonstrated that adults with hypopituitarism of both childhood and adult onset have a diminished quality of life (QOL) in comparison with the normal population. Reductions in physical and mental energy, dissatisfaction with body image and poor memory have been reported most consistently. A specific role for growth hormone (GH) deficiency, as opposed to multiple pituitary hormone deficiency, has been observed for the memory deficit, which extends to both short- and long-term memory. Comparisons with normal siblings have confirmed the reduced QOL, although differences have been small. There is less consensus for a reduction in QOL when hypopituitary subjects are compared with patients with other chronic diseases, with studies supporting (in comparison with diabetics) and refuting (in comparison with patients following mastoid surgery) the reduction in QOL. GH replacement in adults has improved QOL, particularly in the domains of energy level and self-esteem, and memory has improved. The social impact of these changes may be considerable, with patients requiring fewer days' sick leave. A major placebo effect is present, however, and neutral results as well as positive have been reported in placebo-controlled trials. Where a positive effect has been observed, it has been more likely to occur in patients with a low QOL at the outset. It is otherwise impossible to predict at the outset those who will benefit from GH replacement. GH treatment has effects on body composition, exercise capacity, muscle strength, total body water and intermediary metabolism which would be expected to improve QOL. Replacement therapy also has side-effects, and it is the variable balance of the positive and negative effects, coupled with the difficulties of measuring QOL, which have led to the disparate results in the literature. There is probably also a true inter-individual variation, although the mechanisms of this are currently unknown.

Abstract
PURPOSE The cause of fibromyalgia (FM) is not known. Low levels of insulin-like growth factor 1 (IGF-1), a surrogate marker for low growth hormone (GH) secretion, occur in about one third of patients who have many clinical features of growth hormone deficiency, such as diminished energy, dysphoria, impaired cognition, poor general health, reduced exercise capacity, muscle weakness, and cold intolerance. To determine whether suboptimal growth hormone production could be relevant to the symptomatology of fibromyalgia, we assessed the clinical effects of treatment with growth hormone. METHODS Fifty women with fibromyalgia and low IGF-1 levels were enrolled in a randomized, placebo-controlled, double-blind study of 9 months' duration. They gave themselves daily subcutaneous injections of growth hormone or placebo. Two outcome measures--the Fibromyalgia Impact Questionnaire and the number of fibromyalgia tender points-were evaluated at 3-monthly intervals by a blinded investigator. An unblinded investigator reviewed the IGF-1 results monthly and adjusted the growth hormone dose to achieve an IGF-1 level of about 250 ng/mL. RESULTS Daily growth hormone injections resulted in a prompt and sustained increase in IGF-1 levels. The treatment (n=22) group showed a significant improvement over the placebo group (n=23) at 9 months in both the Fibromyalgia Impact Questionnaire score (P <0.04) and the tender point score (P <0.03). Fifteen subjects in the growth hormone group and 6 subjects in the control group experienced a global improvement (P <0.02). There was a delayed response to therapy, with most patients experiencing improvement at the 6-month mark. After discontinuing growth hormone, patients experienced a worsening of symptoms. Carpal tunnel symptoms were more prevalent in the growth hormone group (7 versus 1); no other adverse events were more common in this group. CONCLUSIONS Women with fibromyalgia and low IGF-1 levels experienced an improvement in their overall symptomatology and number of tender points after 9 months of daily growth hormone therapy. This suggests that a secondary growth hormone deficiency may be responsible for some of the symptoms of fibromyalgia.

Abstract
BACKGROUND We examined the effect of growth hormone (GH) administration on the psychological capacity and sense of well-being in 25 patients with adult-onset GH-deficiency (GHD). METHODS Very low dosages [0.5-1.0 UIday(-1) s.c. at bed-time] of recombinant human (rh)-GH (n = 13; aged 50+/-15 years, mean+/-SD) or placebo (n = 12, 53+/-14 years) were given at random for a 6-month period. Quality of life was assessed by using the Italian version of the self-rating Kellner Symptom Questionnaire (KSQ) and the Hamilton Depression Scale (HDS). RESULTS No difference in insulin-like growth factor I (IGF-I) levels was noted between groups on entry to the study. A significant increase in IGF-I [month 0 56.2+/-10.4 microg L(-1) vs. month 6 125.7+/-16.7 microg L(-1); P < 0.001] levels was noted only in the rh-GH-treated group. There was no difference in overall scores on the KSQ between the rh-GH-treated and control groups on entry. A slight, non-significant, decrease in overall scores was noted in both groups of subjects. Subsection analysis of items from the KSQ did not show significant differences in either group during the 6-month period. A significant decrease (month 0 28+/-1 vs. month 6 25+/-1; P = 0.02) in the HDS score was noted in rh-GH-treated but not in placebo-treated patients. There was a significant correlation (rs, -0.56, P = 0.05) between increase in IGF-I levels and decrease in HDS scores in rh-GH treated patients. CONCLUSION The data demonstrate that low rh-GH dosages significantly improve psychological profiles as rated by HDS evaluation in adult-onset patients with GHD. On the other hand, a 6-month period of treatment does not produce any significant differences in quality of life as measured by KSQ between treated patients and placebo controls.
