Effect of growth hormone treatment on quality of life in Japanese children with growth hormone deficiency: an analysis from a prospective observational study.

ABSTRACT: The aim of this study was to assess changes in quality of life (QoL) in Japanese children with GH deficiency (GHD) after 12 mo of GH treatment or with idiopathic short stature (ISS) after 12 mo without treatment. Children with GHD were treated with GH after enrollment. Outcome measures included the parent-rated Child Behavior Checklist (CBCL), the Youth Self-Report Form (YSR), and height standard deviation scores (SDS). Total CBCL scores significantly decreased in children with GHD (n = 152, mean change (standard deviation [SD]) = -3.42 [11.21]) and ISS (n = 129, mean change = -4.82 [10.09]) after 12 mo (p < 0.001). Total YSR scores (mean change = -9.21 [14.07]) and height SDS (mean change = 0.35 [0.38]) significantly decreased in children with GHD (p < 0.001), but were unchanged in children with ISS. The change in total YSR score was significantly correlated with the change in height SDS in children with GHD (r = -0.516, p = 0.003). Our findings demonstrate that GH treatment can improve QoL in Japanese children with GHD. The correlation between the changes in total YSR score and height SDS demonstrated that increased height resulted in improved QoL.

Project description:BackgroundQuantifying the association between adherence and the growth response to growth hormone (GH) treatment is hampered by suboptimal methods of measuring adherence, confounders associated with the growth response, and restriction of the outcome parameters to yearly growth velocities.AimTo investigate the effect of adherence on the two-year growth response to GH treatment in prepubertal children with idiopathic isolated growth hormone deficiency (GHD) participating in the easypod connect observational study (ECOS), a 5-year, Phase IV open-label study to continuously assess real-world adherence via the easypod electronic drug-delivery device.Patients and methodsOutcome measures were change in height standard deviation score (?HSDS), index of responsiveness (IoR), and parameters of two catch-up growth (CUG) curve functions (monomolecular growth curve and second degree polynomial) with adj-HSDS (HSDS minus Target height (TH) SDS) as dependent variable. Inclusion criteria were GHD, naïve to GH treatment, known TH, age <10y in girls and <12y in boys, ?3 measurements, HSDS <-2 at start, complete data on growth and adherence in the first and second year. Linear regression analyses were performed to test the association between adherence (continuous and high vs. low) and the outcome measures, also adjusted for potential clinical confounders (age at start, adj-HSDS at start, birth weight SDS, gestational age (<37 weeks vs ?37 weeks), GH dose, GH max (n = 58)). The formula of IoR already adjusts for confounders.ResultsIn total, 95 patients complied with the inclusion criteria. The strongest associations were found between high adherence in the second year (?91% as cut-off value) and IoR 2y (+0.62), and average adherence and high adherence (?78%) in the first two years and ?HSDS 0-2y (+0.11 SD per 1 injection/week, and +0.34 SD for high vs. low adherence).ConclusionSuboptimal adherence negatively affected the growth response in the first two years of GH treatment.

Project description:BackgroundCountry-specific data on outcomes of treatment with recombinant human growth hormone are lacking. We present such data for children treated with growth hormone in Canada.MethodsWe describe characteristics and outcomes of 850 children (mean age at baseline 8.5 yr) treated with growth hormone constituting the Canadian cohort of the multinational phase IV prospective observational Genetics and Neuroendocrinology of Short-stature International Study (GeNeSIS). The diagnosis associated with short stature was as determined by the investigator. Auxological data were evaluated yearly until near-adult height. Adverse events were assessed in all growth-hormone-treated patients.ResultsThe diagnosis ascribed as the cause of short stature was growth hormone deficiency in 526 children (61.9%), predominantly organic rather than idiopathic, particularly congenital pituitary abnormalities and intracranial tumours. All diagnostic groups with sufficient patients for analysis had increased height velocity standard deviation score (SDS) and height SDS during growth hormone treatment. For patients who reached near-adult height (n = 293), the mean height SDS was within the normal range for about 80% of patients with organic growth hormone deficiency (n = 131) or idiopathic growth hormone deficiency (n = 50), 50% of patients with idiopathic short stature (n = 10) and 46% of patients with Turner syndrome (n = 79). Eleven deaths were reported, 7 in patients with organic growth hormone deficiency. Serious adverse events considered related to growth hormone treatment (n = 19) were isolated except for medulloblastoma recurrence (n = 2) and adenoidal hypertrophy (n = 2).InterpretationGrowth hormone treatment was effective and had a good safety profile in Canadian children. Growth hormone dosages were lower than in the US and global GeNeSIS cohorts, and a greater proportion of treated Canadian children had organic growth hormone deficiency.Study registrationClinicalTrials.gov, no. NCT01088412.

Project description:BackgroundThe study aimed to compare the growth responses to 3 years of growth hormone (GH) treatment in children and adolescents with GH deficiency (GHD) according to idiopathic, organic, isolated (IGHD), and multiple pituitary hormone deficiency (MPHD).MethodsTotal 163 patients aged 2-18 years (100 males and 63 females; 131 idiopathic and 32 organic GHD; 129 IGHD and 34 MPHD) were included from data obtained from the LG Growth Study. Parameters of growth responses and biochemical results were compared during the 3-year GH treatment.ResultsThe baseline age, bone age (BA), height (Ht) standard deviation score (SDS), weight SDS, mid-parental Ht SDS, predicted adult Ht (PAH) SDS, and insulin like growth factor-1 (IGF-1) SDS were significantly higher in the organic GHD patients than in the idiopathic GHD patients, but peak GH on the GH-stimulation test, baseline GH dose, and mean 3-year-GH dosage were higher in the idiopathic GHD patients than in the organic GHD patients. The prevalence of MPHD was higher in the organic GHD patients than in the idiopathic GHD patients. Idiopathic MPHD subgroup showed the largest increase for the ΔHt SDS and ΔPAH SDS during GH treatment, and organic MPHD subgroup had the smallest mean increase after GH treatment, depending on ΔIGF-1 SDS and ΔIGF binding protein-3 (IGFBP-3) SDS. The growth velocity and the parental-adjusted Ht gain were greater in the idiopathic GHD patients than the organic GHD patients during the 3-year GH treatment, which may have been related to the different GH dose, ΔIGF-1 SDS, and ΔIGFBP-3 SDS between two groups. Multiple linear regression analysis revealed that baseline IGF-1 SDS, BA, and MPH SDS in idiopathic group and baseline HT SDS in organic group are the most predictable parameters for favorable 3-year-GH treatment.ConclusionThe 3-year-GH treatment was effective in both idiopathic and organic GHD patients regardless of the presence of MPHD or underlying causes, but their growth outcomes were not constant with each other. Close monitoring along with appropriate dosage of GH and annual growth responses, not specific at baseline, are more important in children and adolescents with GHD for long-term treatment.Trial registrationClinicalTrials.gov Identifier: NCT01604395.

Project description:IntroductionDysmenorrhea is a physical and mental burden for women, negatively affecting health-related quality of life (HRQL) and work productivity. However, data on HRQL and work productivity of Japanese women are scarce.MethodsIn this prospective observational study, 397 Japanese women received low-dose estrogen/progestin (LEP) or non-LEP treatment (non-steroidal anti-inflammatory drugs or Chinese herbal medicines) for primary/secondary dysmenorrhea and completed survey questionnaires online regarding menstrual symptoms, HRQL, and work productivity. Regression analysis was performed to compare the groups and evaluate outcomes over time using the paired t test. Subgroup analysis was performed using stratification by patient background, and correlations between improvement in menstrual symptoms/HRQL and work productivity were investigated using Spearman's rank correlation coefficient.ResultsSignificant reductions in the modified Menstrual Distress Questionnaire (mMDQ) total score were shown in the LEP group (n = 251) (P < 0.01), but not the non-LEP group (n = 146). Significant improvements in HRQL, measured by the 36-Item Short-Form Health Survey v2.0 (SF-36v2.0), were shown in the LEP group, but not the non-LEP group. Improvements were seen in mental component summary and 7/8 domains (role physical, bodily pain, general health, role emotional, mental health, vitality, and social functioning) in the LEP group, but not the non-LEP group. There were no differences in the physical component summary and role functioning in either group. Improvements in work productivity, measured by the modified Work Productivity and Activity Impairment Questionnaire (mWPAI), were greater in the LEP group vs. non-LEP group. Regression analysis showed differences in improvements between the groups in the mMDQ total score, SF-36v2.0, and mWPAI. A correlation between mMDQ or HRQL and work productivity was seen.ConclusionIn Japanese women, dysmenorrhea is associated with reduced HRQL and work productivity. In real-world clinical practice, improvements in physical and mental menstrual symptoms, HRQL, and work productivity were observed with LEP treatment.Trial registrationNCT04607382 (ClinicalTrials.gov).
