Purpose: The aim was to identify factors affecting treatment adherence and to assess the clinical, economic and management impact of growth hormone deficiency treatment using an electronic auto-injector for recombinant human growth hormone (r-hGH) administration in children. Patients and Methods: A literature review was conducted in PubMed up to 31JUL2013, including the following search terms: “growth hormone deficiency”, “human-recombinant growth hormone” and “treatment adherence”. An economic model was developed to estimate the economic benefits of using an electronic injection device. In order to quantify this benefit, potential savings due to growth hormone cartridge optimization were analyzed. Results: From the literature review, the following key factors were found to affect treatment adherence: type of device used, discomfort, complexity of treatment regimens, long-term treatment, age and patient or family understanding of treatment benefits were assessed. A better adjustment to prescribed daily dose (accuracy up to 0.01 mg) with the electronic device results in a better optimization of vials and could save an average of 5% of total treatment costs in terms of doses not wasted, amounting to €245 of potential savings per patient and year of treatment. Conclusion: The use of an electronic device for r-hGH administration and monitoring may provide a better identification of responder and adherent patients. It may also generate savings in annual r-hGH consumption by hospitals and regional healthcare services.

Rhgh Treatment

Abstract Background. Growth hormone plays a vital role in the human body. Its deficiency can lead to numerous disorders, including musculoskeletal system defects. Treatment with recombinant human growth hormone (rhGH) in children suffering from growth hormone deficiency (GHD) increases muscle mass and improves bone structure.Aim. The purpose of this study was to evaluate the angle of trunk rotation (ATR) in patients diagnosed with GHD treated with rhGH and to observe the incidence of scoliosis.Material and Methods. The study was conducted among 50 children diagnosed with GHD. The group consisted of 11 girls and 39 boys aged 6-16. The study group included 50 children: 10 children just qualified for rhGH treatment and 40 patients undergoing this treatment, with different therapy duration. ATR was measured using a Bunnell scoliometer on five levels of the spine: cervical 7 / thoracic 1, thoracic 6, thoracic 12 / lumbar 1, lumbar 3, lumbar 5 / sacral 1.Results. The most numerous asymmetries among the examined group were in the thoracolumbar segment and at the thoracic 6 level. Girls had greater asymmetries compared to boys especially at thoraco – lumbar and lumbar 3 level. There were no statistically significant differences in ATR at any level comparing patients before hormonal treatment and patients undergoing rhGH treatment. The age of the beginning of the therapy, the duration of rhGH therapy, and body mass index (BMI) also had no effect on ATR. Sport activities had a positive impact on the results obtained by scoliometer assessment.Conclusions. The angle of trunk rotation is higher in growth hormone-deficient females than in males. Weight, height, BMI, the time of growth hormone therapy beginning and the duration of this therapy do not influence ATR. The more sport activities, the lower value of the angle of trunk rotation, especially in male patients. Obtained results support the thesis, that treatment with recombinant human growth hormone does not increase the incidence of scoliosis.

ContextLong-acting recombinant human growth hormone (rhGH) has transformed growth hormone deficiency (GHD) treatment. However, the possibility and rationality for flexible time regimen are pending.ObjectiveWe studied the efficacy of biweekly versus weekly PEGylated rhGH (PEG-rhGH) therapy in GHD children.Design, Setting, and PatientsThis multicenter, phase IV trial with a non-inferiority threshold ≥20% enrolled 585 Tanner stage I GHD children.InterventionSubjects randomly received 0.20 mg/kg once-weekly or biweekly PEG-rhGH, or 0.25 mg/kg.w rhGH once daily for 26 weeks.Main Outcome MeasureThe primary outcome was height SD scores for chronological age (HtSDSCA) at week 26 and safety measurements including adverse events (AEs), IGF-2, and IGFBP-2 changes.ResultsAt week 26, the median HtSDSCA changed from −2.75, −2.82, and −2.78 to −2.31, −2.43, and −2.28 with weekly and biweekly PEG-rhGH, and daily rhGH, respectively. The difference in HtSDSCA was 0.17 ± 0.28 between weekly and biweekly PEG-rhGH, and 0.17 ± 0.27 between daily rhGH and biweekly PEG-rhGH, failing the non-inferiority threshold. Nevertheless, the height velocity of children receiving biweekly PEG-rhGH reached 76.42%–90.34% and 76.08%–90.60% that of children receiving weekly PEG-rhGH and daily rhGH, respectively. The rate of AEs was comparable among the groups. No statistical difference was observed in IGF-2 and IGFBP-2 levels among the groups. IGFBP-2 levels decreased over time in all groups, with no notable difference in IGF-2 and IGFBP-2 changes among the three treatment groups.ConclusionsAlthough notably promoted height velocity, biweekly PEG-rhGH failed the non-inferiority threshold as compared with either weekly PEG-rhGH or daily rhGH. Compared with short-term rhGH, long-acting PEG-rhGH did not significantly increase tumor-associated IGF-2 and IGFBP-2 expressions.Clinical Trial Registrationclinicaltrials.gov, identifier NCT02976675.
