RESUMO

BACKGROUND: Recombinant human growth hormone has been used for more than 30 years and its indications have increased worldwide. There is concern that this treatment might increase mortality, but published data are scarce. We present data from the entire dataset of all eight countries of the Safety and Appropriateness of Growth hormone treatments in Europe (SAGhE) consortium, with the aim of studying long-term overall and cause-specific mortality in young adult patients treated with recombinant human growth hormone during childhood and relating this to the underlying diagnosis. METHODS: This cohort study was done in eight European countries (Belgium, France, Germany, Italy, The Netherlands, Sweden, Switzerland, and the UK). Patients were classified a priori based on pre-treatment perceived mortality risk from their underlying disease and followed up for cause-specific mortality. Person-years at risk of mortality and expected rates from general population data were used to calculate standardised mortality ratios (SMRs). FINDINGS: The cohort comprised 24 232 patients treated with recombinant human growth hormone during childhood, with more than 400 000 patient-years of follow-up. In low-risk patients with isolated growth hormone deficiency or idiopathic short stature, all-cause mortality was not significantly increased (SMR 1·1, 95% CI 0·9-1·3). In children born small for gestational age, all-cause mortality was significantly increased when analysed for all countries (SMR 1·5, CI 1·1-1·9), but this result was driven by the French subcohort. In patients at moderate or high risk, mortality was increased (SMR 3·8, 3·3-4·4; and 17·1, 15·6-18·7, respectively). Mortality was not associated with mean daily or cumulative doses of recombinant human growth hormone for any of the risk groups. Cause-specific mortality from diseases of the circulatory and haematological systems was increased in all risk groups. INTERPRETATION: In this cohort, the largest, to our knowledge, with long-term follow-up of patients treated with recombinant human growth hormone during childhood, all-cause mortality was associated with underlying diagnosis. In patients with isolated growth hormone deficiency or idiopathic short stature, recombinant human growth hormone treatment was not associated with increased all-cause mortality. However, mortality from certain causes was increased, emphasising the need for further long-term surveillance. FUNDING: European Union.

RESUMO

CONTEXT: The phenotype and response to GH treatment of children with an IGF1R defect is insufficiently known. OBJECTIVE: To develop a clinical score for selecting children with short stature for genetic testing and evaluate the efficacy of treatment. DESIGN AND SETTING: Case series with an IGF1R defect identified in a university genetic laboratory. PATIENTS AND INTERVENTIONS: Of all patients with sufficient clinical data, 18 had (likely) pathogenic mutations (group 1) and 7 had 15q deletions including IGF1R (group 2); 19 patients were treated with GH. MAIN OUTCOME MEASURES: Phenotype and response to GH treatment. RESULTS: In groups 1 and 2, mean (range) birth weight, length, and head circumference (HC) SD scores (SDSs) were -2.1 (-3.7 to -0.4), -2.7 (-5.0 to -1.0), and -1.6 (-3.0 to 0.0), respectively. At presentation, height, HC, and serum IGF-1 SDSs were -3.0 (-5.5 to -1.7), -2.5 (-4.2 to -0.5), and +1.2 (-1.3 to 3.2), respectively. Feeding problems were reported in 15 of 19 patients. A clinical score with 76% sensitivity is proposed. After 3 years of GH treatment [1.1 (0.2) mg/m2/d] height gain in groups 1 (n = 12) and 2 (n = 7) was 0.9 SDS and 1.3 SDS (at a mean IGF-1 of 3.5 SDS), less than reported for small for gestational age (1.8 SDS). CONCLUSION: A clinical score encompassing birth weight and/or length, short stature, microcephaly, and IGF-1 is useful for selecting patients for IGF1R analysis. Feeding problems are common and the growth response to GH treatment is moderate.

RESUMO

Context: There has been concern that GH treatment of children might increase meningioma risk. Results of published studies have been inconsistent and limited. Objective: To examine meningioma risks in relation to GH treatment. Design: Cohort study with follow-up via cancer registries and other registers. Setting: Population-based. Patients: A cohort of 10,403 patients treated in childhood with recombinant GH in five European countries since this treatment was first used in 1984. Expected rates from national cancer registration statistics. Main Outcome Measures: Risk of meningioma incidence. Results: During follow-up, 38 meningiomas occurred. Meningioma risk was greatly raised in the cohort overall [standardized incidence ratio (SIR) = 75.4; 95% CI: 54.9 to 103.6], as a consequence of high risk in subjects who had received radiotherapy for underlying malignancy (SIR = 658.4; 95% CI: 460.4 to 941.7). Risk was not significantly raised in patients who did not receive radiotherapy. Risk in radiotherapy-treated patients was not significantly related to mean daily dose of GH, duration of GH treatment, or cumulative dose of GH. Conclusions: Our data add to evidence of very high risk of meningioma in patients treated in childhood with GH after cranial radiotherapy, but suggest that GH may not affect radiotherapy-related risk, and that there is no material raised risk of meningioma in GH-treated patients who did not receive radiotherapy.

RESUMO

BACKGROUND: Growth hormone (GH) treatment may unmask central hypothyroidism (CeH). This was first observed in children with GH deficiency (GHD), later also in adults with GHD due to acquired "organic" pituitary disease. We hypothesized that newly diagnosed CeH in children after starting GH treatment for nonacquired, apparent isolated GHD points to congenital "organic" pituitary disease. METHODS: Nationwide, retrospective cohort study including all children with nonacquired GHD between 2001 and 2011 in The Netherlands. The prevalence of CeH, hypothalamic-pituitary (HP) abnormalities, and neonatal congenital hypothyroidism screening results were evaluated. RESULTS: Twenty-three (6.3%) of 367 children with apparent isolated GHD were prescribed LT4 for presumed CeH within 2 years after starting GH treatment. Similarly to children already diagnosed with multiple pituitary hormone deficiency, 75% of these 23 had structural HP abnormalities. In children not prescribed LT4, low pre- or post-GH treatment FT4 concentrations were also associated with structural HP abnormalities. Neonatal screening results of only 4 of the 23 children could be retrieved. CONCLUSION: In children with nonacquired, apparent isolated GHD, a diagnosis of CeH after, or a low FT4 concentration around the start of GH treatment, is associated with congenital structural HP abnormalities, i.e., "organic" pituitary disease. Neonatal values could not be judged reliably.

RESUMO

Context: Growth hormone (GH) is prescribed for an increasing range of indications, but there has been concern that it might raise cancer risk. Published data are limited. Objective: To examine cancer risks in relation to GH treatment. Design: Cohort study. Setting: Population-based. Patients: Cohort of 23,984 patients treated with recombinant human GH (r-hGH) in eight European countries since this treatment was first used in 1984. Cancer expectations from country-specific national population statistics. Main Outcome Measures: Cancer incidence and cancer mortality. Results: Incidence and mortality risks in the cohort were raised for several cancer sites, largely consequent on second primary malignancies in patients given r-hGH after cancer treatment. There was no clear raised risk in patients with growth failure without other major disease. Only for bone and bladder cancers was incidence significantly raised in GH-treated patients without previous cancer. Cancer risk was unrelated to duration or cumulative dose of r-hGH treatment, but for patients treated after previous cancer, cancer mortality risk increased significantly with increasing daily r-hGH dose (P trend < 0.001). Hodgkin lymphoma (HL) incidence increased significantly with longer follow-up (P trend = 0.001 for patients overall and 0.002 for patients without previous cancer). Conclusions: Our results do not generally support a carcinogenic effect of r-hGH, but the unexplained trend in cancer mortality risk in relation to GH dose in patients with previous cancer, and the indication of possible effects on bone cancer, bladder cancer, and HL risks, need further investigation.

RESUMO

BACKGROUND: The long-term safety of growth hormone treatment is uncertain. Raised risks of death and certain cancers have been reported inconsistently, based on limited data or short-term follow-up by pharmaceutical companies. PATIENTS AND METHODS: The SAGhE (Safety and Appropriateness of Growth Hormone Treatments in Europe) study assembled cohorts of patients treated in childhood with recombinant human growth hormone (r-hGH) in 8 European countries since the first use of this treatment in 1984 and followed them for cause-specific mortality and cancer incidence. Expected rates were obtained from national and local general population data. The cohort consisted of 24,232 patients, most commonly treated for isolated growth failure (53%), Turner syndrome (13%) and growth hormone deficiency linked to neoplasia (12%). This paper describes in detail the study design, methods and data collection and discusses the strengths, biases and weaknesses consequent on this. CONCLUSION: The SAGhE cohort is the largest and longest follow-up cohort study of growth hormone-treated patients with follow-up and analysis independent of industry. It forms a major resource for investigating cancer and mortality risks in r-hGH patients. The interpretation of SAGhE results, however, will need to take account of the methods of cohort assembly and follow-up in each country.

RESUMO

STUDY QUESTION: In girls and adolescents with Turner syndrome (TS), is there a correlation between serum AMH levels and karyotype, spontaneous puberty and other biochemical markers of ovarian function, or growth hormone (GH) therapy? SUMMARY ANSWER: Serum anti-Müllerian hormone (AMH) correlates with karyotype, pubertal development, LH, FSH and are measurable in a higher percentage of TS patients under GH therapy. WHAT IS KNOWN ALREADY: Most girls with TS suffer from incomplete sexual development, premature ovarian failure and infertility due to abnormal ovarian folliculogenesis. Serum AMH levels reflect the ovarian reserve in females, even in childhood. STUDY DESIGN, SIZE, DURATION: Cross-sectional study investigating 270 karyotype proven TS patients aged 0-20 years between 2009 and 2010. PARTICIPANTS/MATERIALS, SETTINGS, METHODS: Studies were conducted at three University Children's hospitals in Europe. Main outcome measures were clinical data concerning pubertal development as well as laboratory data including karyotype, serum AMH, LH, FSH, estradiol (E2), inhibin B and IGF. RESULTS AND THE ROLE OF CHANCE: Serum AMH was detectable in 21.9% of all TS girls and correlated strongly with karyotypes. A measurable serum AMH was found in 77% of TS girls with karyotype 45,X/46,XX, in 25% with 'other' karyotypes and in only 10% of 45,X TS girls. A strong relationship was also observed for measurable serum AMH and signs of spontaneous puberty such as breast development [adjusted odds ratio (OR) 19.3; 95% CI 2.1-175.6; P = 0.009] and menarche (crude OR 47.6; 95% CI 4.8-472.9; P = 0.001). Serum AMH correlated negatively with FSH and LH, but did not correlate with E2 and inhibin B. GH therapy increased the odds of having measurable AMH in TS (adjusted OR 4.1; 95% CI 1.9-8.8; P < 0.001). LIMITATIONS, REASONS FOR CAUTION: The cross-sectional design of the study does not allow longitudinal interpretation of the data; for that further studies are needed. High percentage of non-measurable AMH levels in the cohort of TS require categorized analysis.

RESUMO

OBJECTIVE: Short stature is a prominent feature of Turner syndrome (TS), which is partially overcome by GH treatment. We have previously reported the results of a trial on the effect of oxandrolone (Ox) in girls with TS. Ox in a dose of 0.03 mg/kg per day (Ox 0.03) significantly increased adult height gain, whereas Ox mg/kg per day (0.06) did not, at the cost of deceleration of breast development and mild virilization. The aim of this follow-up study in adult participants of the pediatric trial was to investigate the long-term effects of previous Ox treatment. DESIGN AND METHODS: During the previous randomized controlled trial, 133 girls were treated with GH combined with placebo (Pl), Ox 0.03, or Ox 0.06 from 8 years of age and estrogen from 12 years. Sixty-eight women (Pl, n=23; Ox 0.03, n=27; and Ox 0.06, n=18) participated in the double-blind follow-up study (mean age, 24.0 years; mean time since stopping GH, 8.7 years; and mean time of Ox/Pl use, 4.9 years). We assessed height, body proportions, breast size, virilization, and body composition. RESULTS: Height gain (final minus predicted adult height) was maintained at follow-up (Ox 0.03 10.2±4.9 cm, Ox 0.06 9.7±4.4 cm vs Pl 8.0±4.6 cm). Breast size, Tanner breast stage, and body composition were not different between groups. Ox-treated women reported more subjective virilization and had a lower voice frequency. CONCLUSION: Ox 0.03 mg/kg per day has a beneficial effect on adult height gain in TS patients. Despite previously reported deceleration of breast development during Ox 0.03 treatment, adult breast size is not affected. Mild virilization persists in only a small minority of patients. The long-term evaluation indicates that Ox 0.03 treatment is effective and safe.

RESUMO

BACKGROUND/AIMS: To investigate whether short-term changes in body composition as a result of growth hormone therapy could be used to predict its growth effect after 1 year in children with growth hormone deficiency (GHD) and children born small for gestational age (SGA). METHODS: 88 GHD children and 99 SGA children who started treatment with recombinant human growth hormone were included. Total body water (TBW) and height were measured. After 1 year, patients were divided into adequate and inadequate responders. RESULTS: In GHD and SGA children a sensitivity of 87 and 53%, respectively, and a specificity of 58 and 83%, respectively, were found. The positive predictive values for GHD and SGA children were 73 and 90%, respectively. The negative predictive values were 75 and 32%, respectively. CONCLUSION: Changes in body composition data measured by TBW are a valuable tool to correctly predict 75% of the GHD children and are only useful in SGA children when the change in TBW is above the cut-off value of 0.7 l/m(2).

RESUMO

BACKGROUND: The weak androgen oxandrolone (Ox) may increase height but may also affect glucose metabolism in girls with Turner syndrome (TS). METHODS: In a randomized, placebo-controlled, double-blind study, we assessed the effect of Ox at a dosage of either 0.06 or 0.03 mg/kg/day on glucose metabolism in 133 growth hormone (GH)-treated girls with TS. Patients were treated with GH (1.33 mg/m(2)/day) from baseline, combined with placebo (Pl) or Ox from the age of 8, and estrogens from the age of 12. Oral glucose tolerance tests (OGTT) were performed, and HbA1c levels were measured before, during, and after discontinuing Ox/Pl therapy. RESULTS: Insulin sensitivity, assessed by the whole-body insulin sensitivity index (WBISI) decreased during GH+Ox/Pl (p = 0.003) without significant differences between the dosage groups. Values returned to pre-treatment levels after discontinuing GH+Ox/Pl. On GH+Ox, fasting glucose was less frequently impaired (Ox 0.03, p = 0.001; Ox 0.06, p = 0.02) and HbA1c levels decreased more (p = 0.03 and p = 0.001, respectively) than on GH+Pl. CONCLUSIONS: We conclude that in GH-treated girls with TS, Ox at a dosage of 0.03 or 0.06 mg/kg/day does not significantly affect insulin sensitivity. Insulin sensitivity decreases during GH therapy, to return to a pre-treatment level after discontinuing therapy.

RESUMO

OBJECTIVES/HYPOTHESIS: Oxandrolone (Ox) increases height gain but may also cause voice deepening in growth hormone (GH)-treated girls with Turner syndrome (TS). We assessed the effect of Ox on objective and subjective speaking voice frequency in GH-treated girls with TS. STUDY DESIGN: A multicenter, randomized, placebo (Pl)-controlled, double-blind study was conducted. METHODS: One hundred thirty-three patients were included and treated with GH (1.33 mg/m2/d) from baseline, combined with Pl or Ox in a low (0.03 mg/kg/d) or conventional (0.06 mg/kg/d) dose from the age of 8 years and estrogens from the age of 12 years. Yearly from starting Ox/Pl until 6 months after discontinuing GH+Ox/Pl, voices were recorded and questionnaires were completed. RESULTS: At start, mean (±standard deviation [SD]) voice frequency SD score (SDS) was high for age (1.0±1.2, P<0.001) but normal for height. Compared with GH+Pl, voices tended to lower on GH+Ox 0.03 (P=0.09) and significantly lowered on GH+Ox 0.06 (P=0.007). At the last measurement, voice frequency SDS was still relatively high in GH+Pl group (0.6±0.7, P=0.002) but similar to healthy girls in both GH+Ox groups. Voice frequency became lower than -2 SDS in one patient (3%) on GH+Ox 0.03 and three patients (11%) on GH+Ox 0.06. The percentage of patients reporting subjective voice deepening was similar between the dosage groups. CONCLUSIONS: Untreated girls with TS have relatively high-pitched voices. The addition of Ox to GH decreases voice frequency in a dose-dependent way. Although most voice frequencies remain within the normal range, they may occasionally become lower than -2 SDS, especially on GH+Ox 0.06 mg/kg/d.

RESUMO

OBJECTIVE: Untreated girls with Turner syndrome (TS) have short stature, relatively broad shoulders, a broad pelvis, short legs, a high fat mass and low muscle mass. Our objective was to assess the effect of the weak androgen oxandrolone (Ox) on body proportions and composition in growth hormone (GH)-treated girls with TS. DESIGN/PATIENTS: 133 patients were included in a randomized, placebo-controlled, double-blind study. METHODS: Patients were treated with GH (1.33 mg/m(2) per day) from baseline, combined with placebo (Pl) or Ox in a low (0.03 mg/kg per day) or previously conventional (0.06 mg/kg per day) dose from the age of eight, and oestrogens from the age of twelve. Sitting height, biacromial and biiliacal distances compared with height (i.e. shape values), BMI, waist circumference, sum of 4 skinfolds (sum4skin) and upper arm muscle area (UAMA) SD scores (SDS) were assessed half-yearly. RESULTS: Compared with GH + Pl, adult shape values on GH + Ox tended to be higher for sitting height (Ox 0.03, P = 0.2; Ox 0.06, P = 0.02) and biacromial distance (Ox 0.03, P = 0.2; Ox 0.06, P = 0.07) and lower for biiliacal distance (Ox 0.03, P = 0.004; Ox 0.06, P = 0.08). Sum4skin SDS tended to decrease more (Ox 0.03, P = 0.2; Ox 0.06, P = 0.005) while UAMA SDS increased more (Ox 0.03, P < 0.001; Ox 0.06, P < 0.001) than on GH + Pl. The increase in BMI and waist circumference SDS was comparable between the dosage groups. CONCLUSIONS: In GH-treated girls with TS, Ox 0.06 increases sitting height and tends to increase biacromial distance and decrease biiliacal distance, while Ox 0.03 significantly decreases biiliacal distance compared with height. Furthermore, Ox 0.06 reduces subcutaneous fat mass, and both Ox dosages increase muscle mass.

RESUMO

CONTEXT AND OBJECTIVE: GH therapy increases growth and adult height in Turner syndrome (TS). The benefit to risk ratio of adding the weak androgen oxandrolone (Ox) to GH is unclear. DESIGN AND PARTICIPANTS: A randomized, placebo-controlled, double-blind, dose-response study was performed in 10 centers in The Netherlands. One hundred thirty-three patients with TS were included in age group 1 (2-7.99 yr), 2 (8-11.99 yr), or 3 (12-15.99 yr). Patients were treated with GH (1.33 mg/m(2) . d) from baseline, combined with placebo (Pl) or Ox in low (0.03 mg/kg . d) or conventional (0.06 mg/kg . d) dose from the age of 8 yr and estrogens from the age of 12 yr. Adult height gain (adult height minus predicted adult height) and safety parameters were systematically assessed. RESULTS: Compared with GH+Pl, GH+Ox 0.03 increased adult height gain in the intention-to-treat analysis (mean +/- sd, 9.5 +/- 4.7 vs. 7.2 +/- 4.0 cm, P = 0.02) and per-protocol analysis (9.8 +/- 4.9 vs. 6.8 +/- 4.4 cm, P = 0.02). Partly due to accelerated bone maturation (P < 0.001), adult height gain on GH+Ox 0.06 was not significantly different from that on GH+Pl (8.3 +/- 4.7 vs. 7.2 +/- 4.0 cm, P = 0.3). Breast development was slower on GH+Ox (GH+Ox 0.03, P = 0.02; GH+Ox 0.06, P = 0.05), and more girls reported virilization on GH+Ox 0.06 than on GH+Pl (P < 0.001). CONCLUSIONS: In GH-treated girls with TS, we discourage the use of the conventional Ox dosage (0.06 mg/kg . d) because of its low benefit to risk ratio. The addition of Ox 0.03 mg/kg . d modestly increases adult height gain and has a fairly good safety profile, except for some deceleration of breast development.

RESUMO

The weak androgen oxandrolone (Ox) increases height gain in growth-hormone (GH) treated girls with Turner syndrome (TS), but may also give rise to virilizing side effects. To assess the effect of Ox, at a conventional and low dosage, on behavior, aggression, romantic and sexual interest, mood, and gender role in GH-treated girls with TS, a randomized, placebo-controlled, double-blind study was conducted. 133 patients were treated with GH (1.33 mg/m(2)/d) from baseline, combined with placebo (Pl), Ox 0.03 mg/kg/d, or Ox 0.06 mg/kg/d from the age of eight, and with estrogens from the age of 12. The child behavior checklist (CBCL), Junior Dutch Personality Questionnaire (DPQ-J), State-subscale of the Spielberger's State-Trait Anger Scale, Romantic and Sexual Interest Questionnaire, Mood Questionnaire, and Gender Role Questionnaire were filled out before, during, and after discontinuing Ox/Pl. The changes during Ox/Pl therapy were not significantly different between the dosage groups. In untreated patients, the mean CBCL total (P=0.002) and internalizing (P=0.003) T scores, as well as the mean DPQ-J social inadequacy SD score (SDS) (P=0.004) were higher than in reference girls, but decreased during GH+Ox/Pl therapy (P<0.001, P=0.05, P<0.001, respectively). Whereas the mean total (P=0.01) and internalizing (P<0.001) T score remained relatively high, the mean social inadequacy SDS became comparable with reference values. We conclude that in GH-treated girls with TS, Ox 0.03 mg/kg/d or 0.06 mg/kg/d does not cause evident psychological virilizing side effects. Problem behavior, frequently present in untreated girls with TS, decreases during therapy, but total and internalizing problem behavior remain increased.

RESUMO

Cytological cervical screening is rather inefficient because of relatively high proportions of false negative and false positive smears. To evaluate the efficiency of high-risk human papillomavirus (hrHPV) testing, by GP5+/6+ PCR-enzyme immunoassay (EIA), in conjunction with cytology (Intervention Group) to that of the classical cytology (Control Group), we initiated the Population Based Screening Study Amsterdam (POBASCAM). POBASCAM is a population-based randomized controlled trial for implementation of hrHPV testing in cervical screening. The outcome measure is the proportion of histologically confirmed > or =CIN3 lesions in each study arm up to and including the next screening round after 5 years. We present the design, methods and baseline data of POBASCAM. When, in the next 5 years, the follow-up will be completed, the data obtained will be used in model studies, including a cost-effectiveness study, to advise the Dutch Ministry of Public Health in deciding whether cervical screening should be based on combined hrHPV and cytology testing instead of cytology alone. Between January 1999 and September 2002, 44,102 women (mean age = 42.8 years; range = 29-61) that participated in the regular Dutch screening program were included in our study. In the Intervention Group the distribution of cytology and hrHPV by cytology class was as follows: normal cytology 96.6% (3.6% hrHPV positive); borderline and mild dyskaryosis (BMD) 2.5% (34.6% hrHPV positive); and moderate dyskaryosis or worse (>BMD) 0.8% (88.3% hrHPV positive), i.e., 0.4% moderate dyskaryosis (82.9% hrHPV positive), 0.3% severe dyskaryosis (92.5% hrHPV positive), 0.1% carcinoma in situ (95.2% hrHPV positive), <0.1% suspected for invasive cancer (hrHPV positive 100.0%). In the Control Group 96.5% of the women had normal cytology, 2.4% BMD and 0.8% >BMD, i.e., 0.4% moderate dyskaryosis, 0.3% severe dyskaryosis, 0.1% carcinoma in situ, <0.1% suspected for invasive cancer. The presence of hrHPV was age-dependent, decreasing from 12.0% at 29-33 years to 2.4% at 59-61 years. Among women with a positive hrHPV test, the prevalence of BMD was age-dependent ranging from 20.2% at 29-33 years to 7.8% at 54-58 years. In contrast, the risk of >BMD of 13.7% among women with a positive hrHPV test was not age-dependent. Our study indicates that large-scale hrHPV testing by GP5+/6+ PCR-EIA in the setting of population-based cervical screening is practically feasible, is accepted by both participating women and general practitioners and yields highly reproducible results.
