The concept of health-related quality of life (HrQoL) reflects the subjective perception of health and includes aspects of well-being and functioning in physical, emotional, mental and social life domains. Nowadays, HrQoL has become a relevant treatment outcome from epidemiological and clinical perspectives and is also broadly employed in health economic analyses. To assess HrQoL generic as well as condition-specific instruments are used. The former are applicable to a wide range of health conditions and aim at measuring HrQoL across different conditions. The latter focus on capturing the impact of a specific disease. Although HrQoL research in adults is now well-advanced, there are still open questions regarding how to assess HrQoL in pediatric conditions, such as short stature. Eight generic (one chronic-generic) and seven condition-specific (one treatment-specific) instruments used in HrQoL research in short stature of youth are described. Additionally, this mini review identifies a need for further research and indicates potential directions.

ObjectiveGH deficiency (GHD) in adults is characterized by elevated body mass index (BMI), increased waist girth (WG) and increased fat mass (FM). Information about how these indicators of obesity affect the lipid profile and quality of life (QoL) of GHD subjects is scarce. It is also unclear how changes in these indicators brought about by GH replacement influence lipids and QoL.Design and methodsAdult GHD subjects from the Pfizer International Metabolic Database were grouped according to BMI (n=291 with BMI 2, n=372 with BMI 25–30 kg/m2, n=279 with BMI >30 kg/m2), WG (n=508 with normal WG, n=434 with increased WG) and FM (n=357) and according to changes in these variables after 1 year of GH replacement. Serum IGF-I concentrations, lipid concentrations and QoL using the QoL Assessment of GHD in Adults questionnaire were assessed at baseline and after 1 year of treatment.ResultsAt baseline, total and low-density lipoprotein (LDL) cholesterol were similarly elevated in the BMI and WG groups, but high-density lipoprotein (HDL) cholesterol decreased and triglycerides increased with increasing BMI and WG. QoL was progressively poorer with increasing BMI and WG. After 1 year of GH replacement, total and LDL cholesterol and QoL improved in all BMI, WG and FM groups.ConclusionsVariables of obesity adversely affect the already unfavourable lipid profile in GHD subjects by decreasing HDL cholesterol, but do not counteract the positive effect of GH replacement on LDL cholesterol. Similarly, QoL is influenced by obesity, but responds equally well to GH treatment independent of BMI, WG and FM.

Research on the health-related quality of life (HrQoL) impact of short stature and its treatment in children and adolescents has developed recently. Based on a PubMed literature search, studies addressing this issue were identified and considerable methodological problems mainly related to the HrQoL instruments used and conflicting results are discussed in this mini review. Additionally, this mini review identifies a need for further research and indicates potential directions.

ObjectiveThe impact of the aetiology of childhood-onset GH deficiency (CO-GHD) on the clinical presentation during adulthood and the response to GH replacement has been poorly defined. Our study aims to characterize CO-GHD in adults due to different aetiologies and evaluate the effect of 2 years of GH replacement therapy.Design and methodsData from 353 adults with CO-GHD from Pfizer International Metabolic Database KIMS were retrospectively grouped according to GHD aetiology: non-organic disorder (n=147), organic pituitary disease (n=159), and brain tumour (n=47). Extent of pituitary dysfunction, IGF-I concentration, lipid concentrations and quality-of-life (QoL) were assessed at baseline and after 2 years of GH replacement.ResultsGHD was diagnosed at a later age in the organic pituitary group than in the other groups, resulting in a shorter duration of GH treatment during childhood. However, the final height was greater in the organic pituitary group. Panhypopituitarism was most common in the non-organic disorder and in the organic pituitary groups, while isolated GHD was more prominent in the brain tumour group. Serum IGF-I levels were the lowest in the non-organic group. QoL was the poorest in the brain tumour group. Lipid profile and QoL improved significantly during GH replacement.ConclusionThe adverse consequences of CO-GHD in adulthood vary between aetiologies, but improve similarly with GH treatment. It is, therefore, important to consider retesting all patients with CO-GHD in early adulthood and, if persistent severe GHD is confirmed, recommence GH replacement.

Context: The diagnosis of GH deficiency ( GHD) in adults is based on provocative tests of GH release, all influenced by clinical factors. It is unknown whether the amount of residual GH reserve under the cutoff value has any physiological implication. Objectives: We used a large pharmacoepidemiological database of adult GHD (KIMS) and tested the impact of confounding factors on GH release of no greater than 3 mu g/liter after an insulin tolerance test ( ITT) and evaluated its potential physiological role. Design, Settings, and Patients: A total of 1098 patients fulfilled the criteria of having a GH peak of no greater than 3 mu g/liter during ITT as well as documented IGF-I levels. Outcomes: The impact of underlying hypothalamic-pituitary disease, age, gender, body weight, as well as treatment modalities such as irradiation on peak GH level to ITT was evaluated, and the correlations between GH peak and targets of GH action were analyzed. Results: The GH response to ITT was regulated by gender, age, and the number of additional pituitary deficiencies. In a multivariate evaluation, the extent of hypothalamic-pituitary dysfunction was the most important single predictor of GH peak in ITT. GH peaks in ITT were positively related to IGF-I levels and high-density lipoprotein-cholesterol, as well as inversely to triglycerides. Conclusions: Even in adult severe GHD, GH release appears to be regulated by factors defined to play an important role in normal GH secretion. The impact of very low GH release on IGF-I and lipid parameters indicates a persistent physiological role of low GH concentrations in severely affected patients with GHD.

Objective: The aim of the present study was to clarify the relationship between GH deficiency (GHD) and some cardiovascular risk factors and to analyse the effect of GH replacement therapy in a large number of patients over a prolonged period of time. Design: Data for analysis were retrieved from KIMS (Pfizer International Metabolic Database). Serum concentrations of total cholesterol, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol and triglycerides were obtained from 2589 patients at baseline and from 1206 patients after 1 and 2 years of GH replacement therapy. Body mass index (BMI), waist and hip, resting blood pressure and body composition were also measured. Results: At baseline, the unfavourable effects of GHD were most obvious in the lipid profile demonstrating elevated mean total and LDL-cholesterol, in the increased waist circumference and the elevated BMI. The cholesterol concentration, BMI and body composition were significantly adversely affected by a number of factors, including age, sex and the use of anti-epileptic drugs. The therapeutic effect of GH was essentially uniform across the whole population. GH replacement reduced significantly the mean total and LDL-cholesterol, the waist circumference and the fat mass and was maintained during 2 years. Conclusions: This analysis of a large number of patients confirmed that GHD adults present with an increased cardiovascular risk. The sustained improvement of the adverse lipid profile and body composition suggests that GH replacement therapy may reduce the risk of cardiovascular disease and the premature mortality seen in hypopituitary patients with untreated GHD.

Objective: This study set out to determine the change in quality of life (QoL) and healthcare utilization during 2 years of growth hormone (GH) replacement therapy in adults with GH deficiency. Data were compared from three European countries. Design: Analysis was made from KIMS, the Pfizer International Metabolic Database on adult GH deficiency. Methods: QoL and healthcare utilization were measured at baseline and after 1 and 2 years of GH replacement in patient cohorts from Sweden (n = 302), The Netherlands (n = 103) and Germany (n = 98). QoL was assessed by the QoL-Assessment in Growth Hormone Deficient Adults (QoL-AGHDA) questionnaire, and the KIMS Patient Life Situation Form was used to evaluate healthcare utilization. Results: QoL improved significantly (P < 0.0001) and comparably in all three cohorts. The improvement was seen during the first year of treatment and QoL remained improved during the second year. The number of days in hospital was reduced by 83% (P < 0.0001) during GH replacement. There were no country-specific differences either at baseline or during follow-up. The same was true for the number of days of sick leave (reduction of 63%; P = 0.0004). Significant reductions were recorded in the number of doctor visits in each of the three cohorts after 2 years of GH replacement (P < 0.05). Conclusions: This study provides a detailed comparative analysis of GH replacement therapy in GHD patients in three European countries. Despite some differences in treatment strategies, the beneficial effects on QoL, patient-reported outcomes and healthcare utilization are essentially similar in the healthcare environment of Western European countries.

Objective: This study investigated whether baseline status could predict the responsiveness to one-year growth hormone (GH) replacement therapy in adult GH deficient (GHD) patients. Design: A total of 380 European patients with adult onset GHD due to non-functioning pituitary adenoma that had been enrolled in Pfizer International Metabolic Database (KIMS), and that had completed one year of GH replacement therapy within KIMS, were studied. Results: The mean initial dose of GH was 0.22 (SEM 0.01) mg/day and after one year, the mean dose was 0.36 (0.01) mg/day. The mean insulin-like growth factor-I (IGF-I) SD score increased from -1.75 (0.08) at baseline to 0.47 (0.05) after one year. Quality of life (QoL)-Assessment of GHD in Adults (QoL-AGHDA), waist circumference, waist:hip ratio, and serum lipid pattern improved. Women received a higher dose of GH than men after one year, and demonstrated similar treatment response. In multiple stepwise forward regression analyses, the one-year changes in QoL-AGHDA score, waist:hip ratio, and serum low density lipoprotein-cholesterol (LDL-C) level correlated inversely with the baseline values of the same variable. In addition, the change after one year in QoL-AGHDA score correlated inversely with duration of hypopituitarism and baseline serum high density lipoprotein-cholesterol (HDL-C) level, and the change in waist:hip ratio correlated inversely, although more weakly, with baseline serum HDL-C level and UK citizenship and positively with baseline waist circumference and the initial GH dose. The change in serum LDL-C level additionally correlated inversely with the mean GH dose and duration of hypopituitarism and positively with UK citizenship. Conclusions: Baseline status could, with moderate strength, predict the responsiveness in the same variable whereas it could not, or only weakly, predict the response in other variables. Therefore, when the decision to start GH replacement is undertaken, as many outcome variables as possible should be evaluated in order to adequately evaluate the likelihood of clinical benefit. Finally, women have a similar response to GH replacement as men when individualised GH dosing schedules are employed and should therefore be selected for GH therapy to a similar extent.

Objective: To test the hypothesis whether the effects of GH replacement therapy in adults could be affected by prior pituitary irradiation, the baseline characteristics and response to GH were evaluated in adults with severe GH deficiency (GHD), who had received or not irradiation for the treatment of pituitary adenoma or craniopharyngioma. Design: Data from 447 patients, who had received radiotherapy (427 in addition to surgery), and 630 patients, who were operated on but not irradiated for their tumour, were retrieved from Pfizer International Metabolic Database (KIMS) and compared at baseline and 1 and 2 years following the onset of GH replacement. Results: Irradiated and non-irradiated patients exhibited the expected phenotype of GHD at baseline. However, irradiated patients had a greater impairment in the quality of life (QoL), a higher fat mass, lower high-density lipoprotein cholesterol levels and a lower bone mineral content (BMC) than non-irradiated patients. Treatment with GH induced similar changes in both groups. After 1 year of GH replacement, there was an increase in serum IGF-I and fat-free mass, a reduction in fat mass and an improvement in QoL, all changes being equivalent in irradiated and non-irradiated patients. The lipid profile also improved with the irradiated patients showing a better response. These beneficial effects were maintained and the BMC also increased in both groups by the second year of treatment. Conclusions: This analysis shows that prior irradiation for pituitary adenoma or craniopharyngioma does not compromise the beneficial effects of GH replacement therapy.

What form of estrogen to prescribe a young hypopituitary woman with gonadal failure remains an open question despite evidence that oral estrogen therapy induces GH resistance and an increase in fat mass.Using an international surveillance study of hypopituitary patients, we examined two questions: 1) What estrogen is prescribed to young women of fertile years with hypopituitarism? 2) Is there a difference in body composition or IGF-I levels dependent on the type of estrogen prescribed?Six hundred twenty-eight GH-deficient women, aged 18-50 yr, were identified. Three hundred thirteen had normal gonadal function, and 315 were receiving estrogen therapy; of these 14% were using transdermal estradiol, and 86% were taking an oral estrogen preparation (38% oral estradiol, 18% conjugated estrogens, and 30% ethinyl estradiol in the oral contraceptive). There was no difference in weight, waist/hip ratio, or body composition between the women taking different estrogen therapies. However, if the oral estrogen groups were combined, they showed less change in waist and hip measurement and had a greater waist/hip ratio after 1 yr of GH treatment compared with patients with normal gonadal function (0.85 vs. 0.83; P = 0.022). Patients taking ethinyl estradiol had lower age-adjusted IGF-I sd scores and required almost twice the GH dose to achieve an IGF-I sd score that remained lower than patients with normal gonadal function and patients receiving transdermal estradiol.1) The majority of women of fertile years with hypo-pituitarism take oral estrogen replacement therapy. 2) Waist/hip ratio was greater in women taking oral estrogens, and there is indirect evidence that oral estrogens reduce the action of GH on fat mass. 3) Patients using the oral contraceptive had lower IGF-I levels and required twice the GH dose compared with patients receiving transdermal estradiol.

Objective: Sheehan’s syndrome occurs as a result of ischaemic pituitary necrosis due to severe postpartum haemorrhage. It is one of the most important causes of hypopituitarism, and hence growth hormone deficiency (GHD), in developing countries. However, little is known about the effects of growth hormone (GH) replacement therapy in patients with Sheehan’s syndrome. Design: The demographic background characteristics of 91 GH-deficient patients with Sheehan’s syndrome (mean age ± s.d., 46.3 ± 9.4 years) were compared with those of a group of 156 GH-deficient women (mean age ± s.d., 51.5 ± 13.1 years) with a non-functional pituitary adenoma (NFPA). The baseline characteristics and the effects of 2 years of GH replacement therapy were also studied in the 91 patients with Sheehan’s syndrome and an age-matched group of 100 women with NFPA (mean age ± s.d. 44.5 ± 10.2 years). Results: All patients were enrolled in KIMS (Pfizer International Metabolic Database). Patients with Sheehan’s syndrome were significantly younger at pituitary disorder onset, diagnosis of GHD and at entry into KIMS than patients with NFPA (P < 0.01), and had significantly lower insulin-like growth factor I levels (P < 0.001). At baseline, quality of life (QoL) was significantly (P < 0.05) reduced in patients with Sheehan’s syndrome compared with those with NFPA (P < 0.001). With regard to treatment effects, lean body mass increased significantly (P < 0.05), QoL improved significantly (P < 0.05) and total and low-density lipoprotein-cholesterol decreased significantly (P < 0.05) in patients with Sheehan’s syndrome after 1 year of GH replacement therapy. Similar significant changes in QoL and lipid profiles occurred in patients with NFPA after 2 years of GH replacement. Blood pressure remained unchanged in patients with Sheehan’s syndrome, but decreased significantly (P < 0.01) in the group with NFPA after 1 year, before returning to pretreatment levels at 2 years. Conclusions: In conclusion, patients with Sheehan’s syndrome have more severe GHD compared with individuals with NFPA. GH replacement therapy in patients with Sheehan’s syndrome may have beneficial effects on QoL, body composition and lipid profile.

Casanueva FF, Leal A, Koltowska-Haggstrom M, Jonsson P, Goth MI. Traumatic brain injury as a relevant cause of growth hormone deficiency in adults: a KIMS-based study. Objectives To characterize further the clinical manifestations and the efficacy of growth hormone (GH) replacement therapy in patients with adult-onset growth hormone deficiency (GHD) reported in the KIMS (Pfizer's international metabolic database) as caused by traumatic brain injury (TBI) and to compare them with nonirradiated patients whose GHD was due to a nonfunctioning pituitary adenoma (NFPA). Design Observational study. Setting Subjects selected from the KIMS database. Participants Fifty-one patients with GHD resulting from TBI and 688 patients with GHD resulting from NFPA. Both groups were selected from the KIMS and had adult-onset GHD with GH replacement therapy only after KIMS entry and before and after KIMS entry. Interventions Not applicable. Main outcome measures Age, body mass index, age at disease onset, age at disease diagnosis, age at KIMS entry, final height, GH peak at testing, GH replacement dose, routine biochemical analysis, clinical manifestations of disease, and quality of life measurements. Results Patients with TBI were significantly younger at study entry and were younger both at pituitary disease onset and at GHD diagnosis, but they showed a significant delay in treatment. When comparing patients not treated with GH before entering in the KIMS, patients with TBI were significantly shorter (167.2±1.7cm) than those with NFPA (171.6±0.4cm) in final height. TBI patients had lower GH reserves than NFPA patients, and although the latter group experienced more positive changes, both groups benefited from GH replacement therapy. Conclusions Patients with GHD due to TBI showed a significant reduction in height and a reduction in pituitary GH reserve and were diagnosed and treated with inappropriate delay.

Background: Craniopharyngioma is a parasellar tumour that, although benign, tends to behave aggressively. It can occur at any age but most commonly presents in childhood or adolescence. Objectives: To investigate the frequency and severity of problems associated with craniopharyngioma, using the large international database (KIMS) for adult patients with GH deficiency (GHD), and to assess the differences between the adult onset (AO, aged 18 or above) disease and adults with childhood onset (CO) craniopharyngioma. Design: Inclusion criteria were: an established diagnosis of craniopharyngioma, severe GHD and no recent GH treatment. These criteria were fulfilled by 393 (184 female, 209 male) patients; 241 had AO (mean age 28.7±8.7 years) and 152 had CO disease (age 42.0±12.3 years). Disease history, clinical features and anthropometric data were recorded at the time of enrolment in the database, and body composition, serum IGF-I, serum lipids and quality of life (QoL) were assessed. Results: Peak age at onset of craniopharyngioma was 15–20 years. Ninety percent of patients had been treated surgically. CO patients were shorter than AO patients and had much lower IGF-I standard deviation scores (SDS). The majority had hypopituitarism and over 60% had diabetes insipidus. Body mass index (BMI) was higher in AO males (30.2±5.5) than in CO males (28.5±7.5); waist circumference was also greater. Obesity was more common in AO patients (51.8% vs 39.1%). Body composition did not differ between groups. Cholesterol and triglycerides were higher in AO than in CO patients, but high density lipoprotein (HDL)- and low density lipoprotein (LDL)-cholesterol did not differ. Quality of life, assessed by Quality of Life-Assessment of Growth Hormone Deficiency in Adults (QoL-AGHDA) and the Nottingham Health Profile, was markedly reduced in all groups with no significant differences between them; the QoL-AGHDA score correlated with age at onset of both craniopharyngioma and GHD, and also with BMI in AO patients. Conclusions: These data emphasise the generally poor state of health of patients treated for craniopharyngioma, with respect to endocrine and metabolic function, and also the markedly reduced quality of life. In addition to GHD, most patients have evidence of hypothalamic damage with associated obesity, diabetes insipidus and hypopituitarism. Adults with CO craniopharyngioma were shorter, had lower IGF-I, lower BMI, less obesity and slightly lower blood lipid levels than patients with AO craniopharyngioma.

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.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.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%; P0.0001), and panhypopituitarism was more prevalent in CP than in NFPA patients (58.7% vs. 19.8%; P0.0001). 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.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.

Background: Isolated growth hormone deficiency (IGHD) provides the ideal model to characterize GHD without interference from other pituitary deficiencies or their treatment. No study has addressed the question whether adult patients with IGHD differ in clinical presentation or in responsiveness to GH replacement from adult patients with multiple pituitary hormone deficiencies (MPHD) receiving conventional replacement therapy. Patients and methods: Data were retrieved from the outcomes research database KIMS (Pfizer international metabolic database). Patients with IGHD accounted for 9.6% (274/2868) of all GHD patients. Patients were separated according to the timing of onset. In the adult-onset (AO) group, 167 patients with IGHD were compared to 1992 patients with MPHD. In the childhood-onset (CO) group, 107 patients with IGHD were compared to 602 patients with MPHD. To assess the effect of GH replacement after one year, a longitudinal sub-analysis in the AO group was performed comparing 89 IGHD patients to 1234 MPHD patients. The same study was done in the CO group comparing 66 IGHD patients to 386 MPHD patients. Because IGHD patients were significantly younger than MPHD patients, data analysis was also performed after adjustment for gender and age. Results: In the AO group, non-functioning and secreting pituitary adenomas were the most common primary diagnoses in both IGHD and MPHD. Medical history revealed a high prevalence of hypertension and fractures in both subgroups, but also of non-insulin dependent diabetes mellitus. The prevalence of obesity was high and the waist circumference was elevated. The lipid profile was unfavourable in both IGHD and MPHD. IGF-I concentration and SDS were comparable in both subgroup. Quality of life assessed by QoL-AGHDA was equally poor in both IGHD and MPHD. GH replacement therapy induced favourable changes without distinction. In the CO group, the most common cause in both subgroups was idiopathic. Fracture rate was similarly prevalent in both IGHD and MPHD. Obesity was prominent in both subgroups, but BMI and waist circumference were lower in IGHD. Adverse lipid changes were similarly found in both IGHD and MPHD. IGF-I concentration and SDS were significantly higher in the IGHD sub-group compared to the MPHD subgroup. The QoL-AGHDA score was equally abnormal in both IGHD and MPHD. GH replacement achieved similar significant improvement in both subgroups. Conclusions: GHD patients with AO-IGHD and AO-MPHD present with a similar clinical expression and respond similarly to GH replacement. Patients with CO-IGHD are less severely affected by GHD than CO-MPHD patients, but, nevertheless, both groups show a comparable adverse lipid profile and poor quality of life and respond favourably to GH replacement. These findings support the concept that GH alone is responsible for most if not all metabolic aspects of hypopituitary patients receiving conventional replacement therapy, regardless of age of onset or aetiology. As a consequence, GH replacement therapy not only has potential benefit in GHD patients with additional hormonal deficits, but also the indication of treatment must be extended to patients with isolated GHD.

Extreme degrees of obesity may occur in association with hypothalamic tumors, usually after surgical intervention. This phenomenon has been reported to occur in as many as 25–75% of children undergoing extensive surgical extirpation of craniopharyngiomas (Cranio). Because less is known about the auxology of children with Cranio with milder alterations in growth, we undertook a 3-yr longitudinal analysis, using the KIGS database (Pfizer International Growth Database), to study their growth patterns and evolution of weight. We compared the effect of GH therapy on height, weight, and body mass index (BMI) in 199 prepubertal children with diagnosed Cranio treated by surgery and/or radiotherapy to two other groups of children with other causes of organic GH deficiency (OGHD): one with postsurgical and/or postirradiated OGHD (OGHD + S/I; n = 92) and the other with OGHD not due to Cranio and not having undergone either surgery or irradiation (OGHD − S/I; n = 85). At the start of GH therapy, 1) mean chronological (P < 0.0001) and bone (P = 0.0002) ages were youngest in OGHD − S/I and oldest in OGHD + S/I; 2) the mean height sd score (SDS) was lowest in OGHD − S/I and comparably higher in the other two groups (P < 0.0001); 3) mean weight and BMI SDS were greatest in Cranio and least in OGHD − S/I (both P < 0.0001); and 4) the mean initial GH dose prescribed was highest in OGHD − S/I and comparable in the other two groups (P < 0.0001). After 3 yr of GH therapy, 1) mean bone age remained youngest in OGHD − S/I and oldest in OGHD + S/I (P < 0.0001); 2) mean height SDS was highest in Cranio and comparably lower in the other two groups (P = 0.0159); 3) mean weight and BMI SDS remained greatest in Cranio and least in OGHD − S/I (P < 0.0001 and P = 0.0003, respectively); and 4) the mean GH dose remained highest in the OGHD − S/I group and least in the Cranio group (P = 0.0082). There were statistically significant increases within each group between the start of treatment and after 3 yr of GH therapy in height and weight, but not in BMI SDS. Lastly, after 3 yr of GH treatment, children in the Cranio group continued to have disproportionately heavier weight and higher BMI (with the greatest values in those with lower stimulated peak GH concentrations) compared with members of the other two groups, with no salutary effect of GH treatment on weight SDS and a mild improvement in BMI SDS. After S/I treatment, children with Cranio are disproportionately prone to varying degrees of weight gain compared with children with other forms of OGHD. In the present cohort of prepubertal children with Cranio, GH therapy induced excellent linear growth, but failed to have an ameliorative effect on weight gain and had only a slight beneficial effect on BMI gain. Because affected children may have resultant significant long-term medical morbidity and diminished quality of life, it is critical that the mechanism of this phenomenon be determined to devise helpful preventive or therapeutic interventions.

GH replacement (GHR) is well established, and has been widely accepted to be safe in patients with a wide spectrum of pituitary pathologies. However, GHR in patients with treated germ cell tumours (GCTs) remains controversial, and its use has been cautioned (1, 2). Anecdotal experience from our centre and elsewhere (1–3) suggests that vigilant monitoring is mandatory in treated GCTs who are GH replaced. There are no published studies of long-term outcome and recurrence rates after GHR in treated GCTs. We have therefore surveyed our long-term experience with GHR in 18 adult patients with previously treated GCTs and a global experience of 142 patients from the KIMS database (Pfizer International Metabolic Database) in this diagnostic category in order to determine whether GHR plays a role in tumour relapse. This is a longitudinal observational study reporting a single centre experience and global experience using the KIMS database. The study groups comprised 18 consecutive patients with GCT treated at St Bartholomew’s Hospital, London (SBH) (median duration of follow-up from diagnosis of GCT 13 years (range 0.5–44)) and 142 patients with GCT enrolled in the KIMS database (median duration of follow-up 14.8 years (0.7–36.4)). The relapse rates pre-GHR and during GHR and relapse-free survival were evaluated. The characteristic and treatments of SBH and KIMS patients are shown in Table 1. In the SBH cohort, there were three relapses prior to GHR. All three patients had a histological diagnosis of non-germinomatous GCT (NGGCT), and had been treated with chemotherapy and/or surgery as primary treatment; radiotherapy was subsequently used after first relapse of disease; none of the patients received radiotherapy or craniospinal irradiation (CSI) as initial treatment. Four patients, two with germinomatous GCT (GGCT) and two with NGGCT, relapsed after GHR. Of the patients demonstrating a first relapse, only one had been treated previously with CSI. One patient relapsed prior to GHR, and was retreated successfully with external beam radiotherapy to the primary site of disease together with chemotherapy, but subsequently also relapsed after GHR. The estimated relapse rates were 240 and 323 per 10-000 patient-years, pre-GHR and during GHR respectively. The relative risk (RR) of relapsing after GHR was 1.34 (95% confidence interval (95% CI): 0.23–7.83; PZ0.73). Five instances of relapse were reported during KIMS follow-up. Of interest, two of these patients had never been treated with GHR (true nao ¨ve) before KIMS entry. The most relevant comparison of relapse rate during versus prior to GHR is for true nao ¨ve patients. This group had a RR of relapse during KIMS of 3.40 (95% CI: 0.26–101.4; PZ0.36). For the semi- and non-nao ¨ve patients (previously treated with GH within 6 months or !6 months before KIMS entry), the RR of relapse during KIMS was statistically similar to the true nao ¨ve group, or 2.62 (95% CI: 0.45–15.3; PZ0.27). RR for nao ¨ve versus semi- or non-nao ¨ve patients (including pre KIMS experience) was 1.36 (95% CI: 0.28–5.46; PZ0.65), indicating similar reported relapse rates between true nao ¨ve and those not true nao ¨ve. For all KIMS patients, the estimated relapse rates were 26.6 and 77.2 per 10-000 patient-years, pre-KIMS and during KIMS entry respectively. The RR of relapse during KIMS for all patients was 2.90 (95% CI: 0.73–12.13; PZ0.13). Our results do not support the hypothesis that GHR increases the recurrence of GCT. In view of the relative rarity of intracranial GCT, we elected to utilise longitudinal follow-up and calculation of relapse frequency expressed per patient years. Despite the variation in treatment modalities, there appeared to be similar relapse rate before and after exposure to GHR in the SBH cohort. Of particular interest, most relapses were NGGCT, which is well known to have a higher risk of relapse. Furthermore, the risk of relapse is also enhanced with the lack of use of radiotherapy as primary treatment. In general patients with NGGCT and those not treated with CSI appeared to have a worse relapsefree survival but no statistical significance was observed. The data from the KIMS do not provide evidence for an association between GHR and relapse. The KIMS relapse rate appears to be lower pre-KIMS than during KIMS, but the difference was not statistically significant. The disparity in recurrence frequency between the SBH and

the underlying mechanisms remain poorly understood. Growth hormone deficiency (GHD) is prevalent among CCS and has been associated with increased CV risk in adults, but the associations between GHD, GH treatment and CV risk factors have not been previously studied in CCS during childhood. Objective: To examine the associations between GHD, GH treatment, and CV risk factors in CCS 5 years after cancer diagnosis, and 208 sibling controls (112 males, average 13.6, SD 2.4 years) participated in this crosssectional study, which included anthropometry, body composition (by DXA and abdominal CT), and metabolic studies. GHD was defined as peak stimulated GH level

Purpose The Quality of Life in Adult Growth Hormone Deficiency Assessment (QoL-AGHDA) is a disease-specific quality of life measure specific to individuals who are growth hormone deficient. The present study describes the adaptation of the QoL-AGHDA for use in the following four Slavic languages; Czech, Polish, Serbian and Slovakian. Methods The study involved three stages in each language; translation, cognitive debriefing and validation. The validation stage assessed internal consistency (Cronbach's alpha), reproducibility (test-retest reliability using Spearman's rank correlations), convergent and divergent validity (Correlations with the NHP) and known group validity. Results The QoL-AGHDA was successfully translated into the target languages with minimal problems. Cognitive debriefing interviewees (n = 15-18) found the measures easy to complete and identified few problems with the content. Internal consistency (Czech Republic = 0.91, Poland = 0.91, Serbia = 0.91 and Slovakia = 0.89) and reproducibility (Czech Republic = 0.91, Poland = 0.91, Serbia = 0.88 and Slovakia = 0.93) were good in all adaptations. Convergent and divergent validity and known group validity data were not available for Slovakia. The QoL-AGHDA correlated as expected with the NHP scales most relevant to GHD. The QoL-AGHDA was able to distinguish between participants based on a range of variables. Conclusions The QoL-AGHDA was successfully adapted for use in the Czech Republic, Poland, Serbia and Slovakia. Further validation of the Slovakian version would be beneficial. The addition of these new lanaguage versions will prove valuable to multinational clinical trials and to clinical practice in the respective countries.

levels did not differ (patients vs. controls: 701±87 vs. 572±33mg/l, P =0.17), whereas bioactive IGF-I tended to be lower in patients (5.37±0.55 vs. 6.63±0.25mg/l, P < 0.06). Conclusion: The baseline findings of elevated free GH and low bioactive IGF-I support the concept of GH resistance in uremic hemodialysis patients. Using high dose rhGH treatment it was possible to obtain normal responses in total and bioactive IGF-I levels, showing that the GH resistance may be overcome. Nevertheless, our data imply that the response of bioactive IGF-I to GH is subnormal in hemodialysis patients.

Objective: To compare baseline clinical characteristics and 1-year growth hormone (GH) replacement results in patients with adult onset growth hormone deficiency (GHD) caused by traumatic brain injury (TBI) versus nonfunctioning pituitary adenoma (NFPA). Design: Pharmacoepidemiologic survey of hypopituitary adults with GHD. Setting: Records were selected from the KIMS database, which contains information on >8500 patients with GHD, for 168 of whom TBI was identified as a cause. Participants: Both groups (NFPA group, n=207; TBI group, n=29) were age- (at pituitary disorder onset and entry into the KIMS database) and sex-matched (60% men, 40% women), previously not irradiated, and had not received GH. Interventions: Not applicable. Main Outcome Measures: Values given as mean ± SE. Results: The age at GHD diagnosis was 38.8±2.0 years for the TBI group and 41.5±0.5 years for the NFPA group. In both groups, the most frequent additional hypopituitary deficiency was luteinzing hormone/follicle-stimulating hormone, followed by adrenocorticotropic hormone and thyroid-stimulating hormone. The mean GH peak at diagnosis was 1.25±0.42ng/mL in the TBI group, which was significantly lower than that of the NFPA group (2.38±0.7ng/mL). There were no significant statistical differences in medical history, glucose level, lipids, waist circumference, or body composition measurements. Interestingly, patients with TBI were significantly shorter (168.2±1.5cm) than the NFPA patients (172.5±0.6cm). After 1 year of GH treatment, differences were shown in waist, lean mass, heart rate, glucose levels, quality of life as measured by the Quality of Life Assessment in Growth Hormone Deficient Adults and insulin-like growth factor I. Conclusions: Although hypopituitarism secondary to TBI was described more than 50 years ago, it is only now evident that a considerable number of patients experience severe GHD after TBI. It is suspected that a large number of patients after TBI have undiagnosed GHD. The present results confirm that clinical characteristics and GH treatment effects in GHD caused by TBI are indistinguishable from those in GHD caused by NFPA.

ObjectivesDisease-oriented quality of life (QoL) measures that are not preference-based lack legitimacy for direct use in cost-utility analyses. This has prompted the search for other methods for deriving utilities. The QoL Assessment of Growth Hormone Deficiency in Adults questionnaire (QoL-AGHDA) is a disease-oriented measure used to assess impairment in QoL in adults with growth hormone deficiency. The present study was designed to generate a model for deriving utilities from the QoL-AGHDA.MethodsThe EQ-5D, the QoL-AGHDA, and demographic questions were mailed to a random sample (n = 3005) of the Swedish population (response rate 65%). Multiple regression analysis was used to obtain cross-validated parameters of QoL-AGHDA-based utilities. Two models were developed (simple and full versions). The simple version used the EQ-5Dindex (derived from European values) as the dependent variable, and age, sex, and QoL-AGHDA score as independent variables in a regression analysis. The full model utilized all available demographic information. The QoL-AGHDA scores were thus transformed into a single score (0–1), corresponding to the QoL-AGHDA-based utility.ResultsThe simple transformation algorithm was U (QoL-AGHDA-based utilities) = 1.05 − 0.0189 × QoL-AGHDA score − 0.00238 × age − 0.0127 × sex (male = 0; female = 1). The mean of the weighted estimate for the population (n = 1752) was 0.85 (SD 0.10). The estimate for men (n = 861; mean 0.86; SD 0.10) was higher (P < 0.001) than for women (n = 891; mean 0.84; SD 0.10).ConclusionFor practical reasons, the simple model can be recommended for deriving utilities directly from the QoL-AGHDA for the Swedish population.

ObjectivesTo assess the psychometric properties of the disease-specific Quality of Life Assessment of Growth Hormone Deficiency in Adults (QoL-AGHDA) questionnaire in a general population, and collect French normative data.MethodsA postal survey was conducted on 2900 adult panelists representative of the French population. The participants were asked to complete a questionnaire including the QoL-AGHDA and an evaluation of their overall health status (OHS). The QoL-AGHDA score ranges from 0 to 25, a lower score indicating better QoL. Psychometric properties of the QoL-AGHDA were assessed. The mean QoL-AGHDA scores were described by sex and age groups.ResultsThe return rate was 75%. The quality of completion and internal consistency reliability were good: 95% of the respondents completed all 25 QoL-AGHDA items and Cronbach's alpha was 0.86. The QoL-AGHDA score was able to discriminate between the respondents according to their OHS (from 1.5 for excellent to 12.3 for poor OHS, P < 0.001). The mean QoL-AGHDA score was 4.6 for the overall population, 5.1 for females and 4.2 for males, and ranged from 4.8 for the youngest to 6.1 for the oldest respondents.ConclusionsThe QoL-AGHDA questionnaire showed good psychometric properties when administered in the French population. French reference values were collected, completing the QoL-AGHDA normative database already available in several European countries.

52,554PLN; for patients with age = 9% at 50,139 PLN and for patients with age = 10% at 32,689PLN. In the same patient groups in the analysis for insulin glargine vs pre mix costs per QALY were estimated at 47,171PLN; 40,055PLN; 23,980PLN respectively. CONCLUSIONS: The analysis showed that glargine compared to NPH and premix is a cost effective option for treatment of type 2 diabetes in Poland in patients with baseline HbA1c above 8% and age below 65 years. The results of the cost utility analysis are well below the cost—effectiveness threshold in Poland (equals to 83,239 PLN/QALY).
