Response to Recombinant Human Growth Hormone (rhGH) Therapy in Children with Growth Hormone Deficiency.

OBJECTIVE: To determine the auxological response to recombinant human growth hormone (rhGH) therapy in children with growth hormone deficiency (GHD) presenting at the National Institute of Child Health, Karachi, Pakistan. STUDY DESIGN:  Observational study. Place and Duration of the Study: Department of Paediatric Endocrinology, National Institute of Child Health, Karachi, Pakistan, from January 2022 to December 2023. METHODOLOGY:  All pre-pubertal children with short stature aged 3-12 years diagnosed with GHD and who were prescribed rhGH therapy were included in the study. Children with any other underlying reason for short stature or any other comorbidity were excluded. Patients' demographics and baseline growth parameters were recorded in a pre-designed proforma. Patients were then followed up every three months till one year. Response to rhGH therapy was evaluated through comparison of growth parameters before and after one year of therapy. RESULTS: A total of 90 children including 47 (52.2%) males and 43 (47.8%) females with GHD were enrolled. Mean age of these patients was 7.92 ± 2.647 years. A statistically significant change in height (SD), Weight (SD), and BMI (SD) was observed before and after one year of therapy (p <0.001). Response to therapy in terms of height did not differ significantly with respect to gender (p = 0.955) or stimulated growth hormone levels (p = 0.911). However, response to rhGH therapy was significantly better in terms of increase in height, weight, and BMI in patients presenting earlier i.e. at age ≤8 years. CONCLUSION: Recombinant human growth hormone therapy was effective in children with short stature to achieve desirable growth. Children diagnosed and treated at a younger age (≤8years) achieve better height outcomes as compared to those presenting late. KEY WORDS:  Short stature, Growth hormone deficiency, Recombinant human growth hormone.

Healthcare professionals' perspectives towards the digitalisation of paediatric growth hormone therapies: expert panels in Italy and Korea.

Introduction: To analyse the perspectives of healthcare professionals (HCPs) regarding the acceptance of digital health solutions for growth hormone (GH) deficiency care. This study identified factors impacting HCPs' intent to use and recommend digital solutions supporting recombinant-human growth hormone (r-hGH) therapy in Italy and Korea with a use case of connected drug delivery system (Aluetta® with Smartdot™) integrated in a platform for GH treatment support (the Growzen™ digital health ecosystem). Methods: Participatory workshops were conducted in Rome, Italy, and Seoul, Korea, to collect the perspectives of 22 HCPs on various predefined topics. HCPs were divided into two teams, each moderated by a facilitator. The workshops progressed in five phases: introduction of the project and experts, capturing views on the current context of digitalisation, perceived usefulness and ease of use of Aluetta® with Smartdot™, exploration of the perception of health technology evolution, and combined team recommendations. Data shared by HCPs on technology acceptance were independently analysed using thematic analysis, and relevant findings were shared and validated with experts. Results: HCPs from both Italy and Korea perceived Aluetta® with Smartdot™ and the Growzen™ based digital health ecosystem as user-friendly, intuitive, and easy-to-use solutions. These solutions can result in increased adherence, a cost-effective healthcare system, and medication self-management. Although technology adoption and readiness may vary across countries, it was agreed that using digital solutions tailored to the needs of users may help in data-driven clinical decisions and strengthen HCP-patient relationships. Conclusion: HCPs' perspectives on the digitalisation in paediatric GH therapies suggested that digital solutions enable automatic, real-time injection data transmission to support adherence monitoring and evidence-based therapy, strengthen HCP-patient relationships, and empower patients throughout the GH treatment process.

Primary response in GHD children treatment as a predictor for long-term therapy effectiveness therapy effectiveness.

INTRODUCTION: Short stature in growth hormone deficiency (GHD) can be treated with recombinant human growth hormone (rhGH), which is proven to be both safe and effective. However, a considerable number of patients does not achieve satisfying therapy outcomes. AIM OF THE STUDY: To evaluate the predictive effect of height increase in the first year of rhGH treatment on long-term therapy outcomes. MATERIAL AND METHODS: 165 short-stature children (mean age 10.72 ±3.33 years; 63% males), diagnosed with GHD, treated with rhGH for at least one year (mean follow-up 4.32 ±1.80 years), divided into 2 groups according to the change in height standard deviation score (SDS) after the first year of rhGH treatment: good responders (GR) and poor responders (PR). Then, in one-year intervals, patient's chronological age, bone age, height, weight, insulin-like growth factor level, and rhGH dose were all assessed. RESULTS: In the GR group, mean height velocity SDS up to five years of observation was 1.19 ±0.41/year and in the PR group 0.59 ±0.38/year. The differences were statistically significant (p < 0.05). CONCLUSIONS: The primary response to the rhGH treatment in GHD children seems to be a good predictor for long-term therapy outcomes.

Therapeutic efficacy of recombinant human growth hormone in children with different etiologies of dwarfism from a pharmacoeconomic point of view.

Treatment outcomes for different causes of childhood dwarfism vary widely, and there are no studies on the economic burden of treatment in relation to outcomes. This paper compared the efficacy and healthcare costs per unit height of recombinant human growth hormone (rhGH) for the treatment of growth hormone deficiency (GHD) and idiopathic short stature (ISS) with a view to providing a more cost-effective treatment option for children. We retrospectively analyzed 117 cases (66 cases of GHD and 51 cases of ISS) of short-stature children who first visited Weifang People's Hospital between 2019.1 and 2022.1 and were treated with rhGH for 1 to 3 years to track the treatment effect and statistically analyzed by using paired t tests, non-parametric tests, and chi-square tests, to evaluate the efficacy of rhGH treatment for GHD and ISS children and the medicinal cost. The annual growth velocity (GV) of children with GHD and ISS increased the fastest during 3 to 6 months after treatment and then gradually slowed down. The GV of the GHD group was higher than that of the ISS group from 0 to 36 months after treatment (P < .05 at 3, 6, 9, and 12 months); the height standard deviation scores (HtSDS) of the children in the GHD and ISS groups increased gradually with the increase of the treatment time, and the changes in the height standard deviation scores (ΔHtSDS) of the GHD group were more significant than those of the ISS group (P < .05 at 3, 6, 9, and 12 months). (2) The medical costs in the pubertal group for a 1-cm increase in height were higher than those of children in the pre-pubertal group at the same stage (3 to 24 months P < .05). The longer the treatment time within the same group, the higher the medical cost of increasing 1cm height. RhGH is effective in treating children with dwarfism to promote height growth, and the effect on children with GHD is better than that of children with ISS; the earlier the treatment time, the lower the medical cost and the higher the comprehensive benefit.

Short Adult Height After Rapid-tempo Puberty: When is it too Late to Treat?

A rarely reported phenomenon of rapid-tempo puberty in which the physical changes of puberty and testosterone levels increase very rapidly has not been reported outside apart from in two reviews. The resulting rapid advancement of skeletal age causes early completion of growth with shorter adult stature than expected. This appears to be genetic given its occurrence in the present report in two families, one with three brothers, one with two. We also describe potential treatments and found for the youngest that early initiation of standard therapy preserved or reclaimed adult height (AH) potential. The foreshortened AH in this situation involves rapidly advancing puberty resulting from high circulating testosterone levels leading to rapid advance in skeletal age. This was recognized earlier among younger brothers and treatment with gonadotropin-releasing analogues, growth hormone (GH) and/or aromatase inhibitor therapy (AIT) was tried. Two brothers in family A and family B were treated. Case 5 started treatment early enough so his AH was within target height (mid-parental height) range. Cases 2, 3, 4 were tried on GH and/or AIT with outcomes suggesting benefit. The prevalence and mechanism of rapid-tempo puberty requires further study. Furthermore, as illustrated by two of the current cases, this phenomenon may have a heightened prevalence, or at least may occur, in children previously diagnosed with constitutional delay of growth, underscoring the need to be cautious in assurance of a normal AH outcomes in this population, based on data from a single assessment.

Childhood growth hormone treatment: challenges, opportunities, and considerations.

With long standing demand and popularity, growth hormone treatments continue to be a topic of interest for paediatric endocrinologists and general paediatricians due to ongoing issues regarding their long-term effects, the safety of childhood treatment, and the introduction of long-acting growth hormone preparations in the past decade. Moreover, uncertainty regarding how to approach individual patients and their treatment indications remains, particularly concerning tailored treatment goals and objectives; this uncertainty is further complicated by the multitude of approved indications that surpass substitution therapy. The paediatric endocrinologist thus grapples with pertinent questions, such as what defines reasonable treatment goals for each individual given their indications, and when (and how) to initiate the necessary discussions about risks and benefits with patients and their families. The aim of this Review is to offer advanced physiological concepts of growth hormone function, map out approved paediatric indications for treatment along with evidence on their effects and safety, highlight controversies and complexities surrounding childhood growth hormone treatment, and discuss the potential of long-acting growth hormone and future directions in the realm of childhood growth hormone treatment.

Clinical characteristics of and growth hormone treatment effects on short stature with type 1 insulin-like growth factor receptor (IGF1R) gene alteration.

Short stature with IGF-1 receptor (IGF1R) gene alteration is known as small-for-gestational-age (SGA) short stature with elevated serum IGF1 levels. Its prevalence and clinical characteristics remain unclear. No adapted treatment is available for short stature related to IGF1R gene alteration in Japan, and genetic testing is not yet widely accessible. We investigated short stature with IGF1R gene alterations and analyzed the clinical data of 13 patients using the results of questionnaires issued to the Japanese Society for Pediatric Endocrinology. Four cases were caused by a deletion of chromosome 15q26.3, and eight were caused by heterozygous pathogenic variants in the IGF1R gene. Cases with deletions showed a more severe degree of growth impairment (-4.5 ± 0.43 SD) than those caused by pathological variants (-2.71 ± 0.15 SD) and were accompanied by neurodevelopmental delay. However, cases caused by pathological variants lacked distinctive features. Only three of the 12 cases demonstrated serum IGF1 values exceeding +2 SD, and the other three had values below 0 SD. Four patients did not meet the criteria for SGA at birth. Six patients received GH therapy for SGA short stature and showed improvement in growth rate without any side effects or elevated serum IGF1 levels during treatment. Elevated IGF1 levels (over +2 SD) after GH treatment should be considered a suspicious finding. Owing to the lack of distinctive features, there was a possibility of undiagnosed cases of this condition. Promoting genetic testing and clinical trials on GH administration for this condition is recommended.

Exploring height outcomes with adjuvant aromatase inhibition in growth hormone-deficient male survivors of childhood cancer.

BACKGROUND: Aromatase inhibitors (AI) may improve height in short stature conditions; however, the effect in childhood cancer survivors (CCS) is unknown. We assessed final adult height (FAH) in CCS treated with AI and GH compared with those treated with GH alone. METHODS: Retrospective cohort study of GH-deficient male CCS treated between 2007 and 2023. FAH was noted as the height at the fusion of growth plates or 18 years of age. Multivariable linear regression was used to examine treatment association with FAH, adjusting for other risk factors. RESULTS: Ninety-two patients were included; 70 were treated with GH and 22 with combination AI/GH. The mean age at GH initiation did not differ between groups. The mean age at AI initiation was 13.7 ± 1.9 years. A greater proportion of patients in the AI/GH group were treated with stem cell transplantation, abdominal radiation, total body irradiation, and cis-retinoic acid (p < .01). Multivariable linear regression demonstrated no significant treatment association with FAH Z-score (ß = 0.04, 95% CI: -0.9 to 0.9). History of spinal radiation (ß = -0.93, 95% CI: -1.7 to -0.2), lower starting height Z-score (ß = -0.8, 95% CI: -1.2 to -0.4), and greater difference between bone age and chronological age (ß = -0.3, 95% CI: -0.5 to -0.07) were associated with lower FAH Z-score. CONCLUSIONS: Adjuvant AI was not associated with increased FAH in male CCS compared with GH monotherapy. Future work is needed to determine the optimal adjunctive treatment to maximize FAH for this population.

Post hoc subgroup analysis of Asian children with paediatric GHD from the global phase 3 efficacy and safety study of once-weekly somatrogon vs. once-daily somatropin.

OBJECTIVES: Somatrogon is a long-acting recombinant human growth hormone used to treat patients with paediatric growth hormone deficiency (pGHD). This global phase 3 study compared the efficacy and safety of once-weekly somatrogon with once-daily somatropin in children with GHD. METHODS: Prepubertal patients were randomized 1:1 to once-weekly somatrogon (0.66 mg/kg/week) or once-daily somatropin (0.24 mg/kg/week) for 12 months. The primary endpoint was height velocity (HV) at month 12; secondary endpoints included HV at month 6 and change in height standard deviation score (SDS) at months 6 and 12 and insulin-like growth factor 1 (IGF-1) SDS. RESULTS: This post hoc subgroup analysis focused specifically on Asian children (somatrogon: n=24 and mean age=7.76 years; somatropin: n=21 and mean age=8.10 years) across eight countries. Mean HV at month 12 was 10.95 cm/year (somatrogon) and 9.58 cm/year (somatropin); the treatment difference of 1.38 cm/year favoured somatrogon. The lower bound of the two-sided 95 % CI of the treatment difference (somatrogon-somatropin) was -0.20, similar to the overall study population (-0.24). Compared with the somatropin group, the somatrogon group had numerically higher HV at month 6 (8.31 vs. 11.23 cm/year); a similar trend was observed for height SDS and IGF-1 SDS at months 6 and 12. Safety and tolerability were similar between treatment groups; adverse events occurred in 83 % of somatrogon-treated children and 76 % of somatropin-treated children. CONCLUSIONS: This subgroup analysis demonstrated that somatrogon efficacy and safety in Asian children were consistent with the overall study population, where once-weekly somatrogon was non-inferior to once-daily somatropin.

[Growth Hormone treatment in children with Growth Hormone deficiency, idiopathic short stature, SHOX gene mutation, small for gestational age and Turner syndrome]. / Tratamiento con Hormona de Crecimiento en pacientes con déficit de hormona de crecimiento, talla baja idiopática, mutación gen SHOX, pequeños para edad gestacional y síndrome de Turner.

Growth hormone (GH) is effective in improving height in several conditions. OBJECTIVE: To describe the evolution of a group of children who received GH in a tertiary center between 2012-2022. PATIENTS AND METHOD: Descriptive, retrospective study. We analyzed the impact on height after GH use with Z-score according to etiology, age at onset and bone age. Patients under 15 years old at baseline and receiving GH for at least 12 months, with diagnoses of GH deficiency (GHD), idiopathic short stature (ISS), small for gestational age (SGA), SHOX Haploinsufficiency (SHOX) and Turner syndrome (TS) were included. Height was expressed as Z-score for age and sex, according to NCHS curves. RESULTS: 145 children received GH. Sixty patients were excluded due to irregular administration, incomplete data, less than 12 months of GH, change of hospital, and associated comorbidities. Seventy-three patients were analyzed, 23 GHD, 15 ISS, 20 SGA, 9 SHOX and 6 TS patients. Significant improvement in height (Z-score for age and sex) was observed in SGA (1.4 ± 0.8 gain; p < 0.001), GHD (1.1 ± 1.0; p < 0.001), ISS (1.1 ± 0.8; p < 0.001) and SHOX (0.8 ± 0.7; p = 0.007) patients. In TS, a non-statistically significant improvement was observed (0.7 ± 0.8; p = 0.085). In GHD, onset before 3 years showed a gain of 1.9 ± 1.1, vs 0.7 ± 0.6 (p = 0.083) and in ISS onset with bone age less than 9 years increased it by 1.7 ± 0.5 vs 0.5 ± 0.5 (p < 0.001). ADVERSE EVENTS: 27/73 (37%) headache, 18/73 (24%) lower extremity pain, 1/73 (1.5%) dizziness, 1/73 (1.5%) scoliosis, 1/73 (1.5%) epiphysiolysis and 1/73 (1.5%) craniopharyngioma recurrence. CONCLUSIONS: Children with GHD, ISS, SHOX mutation and SGA significantly improved their height, highlighting in GHD and ISS the importance of early treatment. Treatment was well tolerated in the 5 groups analyzed.

Adding Letrozole to Growth Hormone and Gonadotropin-Releasing Hormone Analog Increases Height in Girls With Short Stature: A Hospital Record-Based Retrospective Study.

OBJECTIVE: There have been rare data on letrozole for height improvement in girls. This study aimed to clarify the efficacy and safety of combination therapy with recombinant human growth hormone (rhGH), GnRHa, and letrozole in improving the height of girls with short stature and advanced bone age. METHODS: This was a hospital record-based retrospective study. Follow-up was conducted on girls with short stature who received treatment with rhGH, GnRHa, and letrozole in our hospital. The treatment group included a total of 29 participants. Before treatment, the mean age of the patients was 11.17 years, and the mean treatment duration was 17.31 months. The control group consisted of 29 short-statured girls who received rhGH/GnRHa treatment, with the mean age and treatment duration of 12.43 years and 16.59 months, respectively. RESULTS: The predicted adult heights (PAHs) before and after treatment were 155.38 and 161.32 cm (P < .001). The ΔPAH in the treatment group was 4 cm higher than that in the control group (5.85 vs 1.82 cm, P < .001). Significant differences were noted in the height standard deviation scores of bone age (P < .001) and chronological age (P = .003) before and after treatment. There was an increasing body mass index during therapy (P = .039). The height gain was 8.71 ± 4.46 cm, and the growth rate was 6.78 ± 3.84 cm per year. CONCLUSION: Combined treatment with GH, GnRHa, and letrozole can enhance the adult height and PAH in short-statured girls, and no significant side effects have been reported.

Linear growth in children and adolescents with congenital adrenal hyperplasia.

PURPOSE OF REVIEW: Congenital adrenal hyperplasia (CAH) is a relatively common disorder and one of the most challenging conditions seen by pediatric endocrinologists. Poor linear growth in CAH has been recognized for many years. There are new insights to explain this abnormality and shed light on strategies to promote normal growth. RECENT FINDINGS: Published data suggest that the dose of hydrocortisone during two critical periods of rapid growth, namely infancy and at puberty, has a fundamental effect on growth velocity, and by definition adult height. To prevent over-treatment, hydrocortisone dosage should remain within the range of 10-15 mg/m 2 body surface area per day. Precursor steroids such as 17-hydroxy progesterone (17OHP) should not be suppressed to undetectable levels. In fact, 17OHP should always be measurable, as complete suppression suggests over-treatment. SUMMARY: CAH is a challenging disorder. High-quality compliance within the consultation setting, with the patient seeing the same specialist at every visit, will be rewarded by improved long-term growth potential. Quality auxological monitoring can avoid phases of growth suppression. New therapy with CRH receptor antagonists may lead to a more nuanced approach by allowing fine tuning of hydrocortisone replacement without the need to suppress ACTH secretion.

Heightism, growth hormone treatment, and social functioning: a holistic approach to a persistent clinical challenge.

PURPOSE OF REVIEW: Use of recombinant human growth hormone (rhGH) treatment to increase height in children with non-growth hormone deficient short stature is becoming more common. Yet, the evidence to support the notion that augmenting height directly leads to increased well being, specifically psychosocial well being, is inconsistent, with high-quality evidence lacking. RECENT FINDINGS: Review of recent studies demonstrates that the association between height augmentation and psychosocial well being is complex. The direct contribution of height to well being may be less than the current model of clinical care of short stature assumes. Rather, the new studies provide evidence to support a role for psychosocial factors, including height-related beliefs, social support, and coping skills, in promoting psychosocial well being, specifically quality of life and self-esteem. SUMMARY: Clinical care of short stature would benefit from incorporating a holistic model of care that considers psychosocial interventions in addition to, or instead of, rhGH treatment.

Update on the use of long-acting growth hormone in children.

PURPOSE OF REVIEW: After extensive research and many years of waiting, long-acting growth hormone (LAGH) formulations have finally become a reality in clinical practice and emerge as a potential solution to address the challenges of daily injections of recombinant human GH (rhGH). In this review, we present a brief history of the development of LAGH and provide a critical analysis of the existing literature on the five LAGH available and approved to date for treatment in children. RECENT FINDINGS: In clinical trials, LAGH therapy has shown noninferiority compared with daily rhGH therapy in promoting linear growth in children with GH deficiency, with similar rates of adverse events. SUMMARY: In the real world, many questions still need to be answered, such as whether a specific group of patients will benefit most from the weekly injection, whether compliance will be better compared with daily rhGH, whether long-term efficacy, monitoring and safety profile will be the same for the different LAGH compounds, and whether the cost-effectiveness will justify their use in different settings.

Effects of growth hormone therapy on the onset and progression of pubertal development in girls with idiopathic short stature.

OBJECTIVE: The aim of this study was to explore the impact of growth hormone (GH) therapy on the onset and progression of puberty in girls with idiopathic short stature. METHODS: This study included 541 girls aged between 4.5 and 10.6 years who were receiving GH treatment, monitored over a 22-year follow-up period. Of these, 126 girls have been followed up to the onset of menarche. The participants were divided into two groups: a ISS control group (n = 66) and a group receiving daily GH treatment at a dose of 0.15 iu/kg (n = 60). We assessed the pubertal development and GH usage of these girls every three months. RESULTS: (1) There was no significant difference in the onset of puberty between the growth hormone (GH) treatment group and the control group; however, the average duration of puberty was longer in the treatment group compared to the control group. (2) During puberty, there were no significant differences in height growth between the treated and untreated groups. (3) The duration of GH treatment showed a significant negative correlation with the age at onset of gonadal development and the age at menarche in females within the treatment group. CONCLUSION: GH treatment does not seem to accelerate the onset of puberty but may extend its duration, without significantly impacting height growth during puberty. Additionally, longer GH treatment duration is linked to earlier gonadal development and menarche in females.

Growth in children with nephrotic syndrome: a post hoc analysis of the NEPTUNE study.

BACKGROUND: Steroids, the mainstay of treatment for nephrotic syndrome in children, have multiple adverse effects including growth suppression. METHODS: Anthropometric measurements in children < 18 years enrolled in the Nephrotic Syndrome Study Network (NEPTUNE) were collected. The longitudinal association of medication exposure and nephrotic syndrome characteristics with height z-score and growth velocity was determined using adjusted Generalized Estimating Equation regression and linear regression. RESULTS: A total of 318 children (57.2% males) with a baseline age of 7.64 ± 5.04 years were analyzed. The cumulative steroid dose was 216.4 (IQR 61.5, 652.7) mg/kg (N = 233). Overall, height z-scores were not significantly different at the last follow-up compared to baseline (- 0.13 ± 1.21 vs. - 0.23 ± 1.71, p = 0.21). In models adjusted for age, sex, and eGFR, greater cumulative steroid exposure (ß - 7.5 × 10-6, CI - 1.2 × 10-5, - 3 × 10-6, p = 0.001) and incident cases of NS (vs. prevalent) (ß - 1.1, CI - 2.22, - 0.11, p = 0.03) were significantly associated with lower height z-scores over time. Rituximab exposure was associated with higher height z-scores (ß 0.16, CI 0.04, 0.29, p = 0.01) over time. CONCLUSION: Steroid dose was associated with lower height z-score, while rituximab use was associated with higher height z-score.

Efficacy, safety, and patient satisfaction of norditropin and sogroya in patients with growth hormone deficiency: a systematic review and meta-analysis of randomized controlled trials.

INTRODUCTION: Growth hormone deficiency occurs when the pituitary gland does not produce enough growth hormone. Norditropin®, a recombinant human growth hormone, and Sogroya®, an albumin-binding growth hormone derivative, are prescribed for patients with growth hormone deficiency. This systematic review assesses the efficacy, safety, and patient satisfaction associated with Norditropin and Sogroya. METHODS: We systematically searched PubMed, Web of Science, and Scopus databases to identify eligible comparative studies. All studies published until June 2023 were included in our analysis. Our outcomes for children included height velocity and height velocity standard deviation score. In contrast, adult outcomes included adverse events, insulin-like growth factor 1-standard deviation score (IGF-1 SDS), and the Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9). Results are reported as odds ratio (OR) and mean difference (MD) with a 95% confidence interval (95% CI). RESULTS: Ten studies involving 1058 participants (665 children and 393 adults) were included in the meta-analysis. In children, Norditropin at doses of 0.034 and 0.067 mg/kg/day was compared to Sogroya at doses of 0.04, 0.08, 0.16, and 0.24 mg/kg/week. The results showed that 0.034 mg/kg/day Norditropin had a favorable impact on height velocity (MD -2.01, 95% CI -3.7 to -2.12, p < 0.00001) and height velocity standard deviation score (Mean Difference -3.61, 95% CI -5.06 to -2.16, p < 0.00001) when compared to Sogroya 0.04 mg/kg/day. Other doses showed comparable results. In adults, the only significant side effect noted was rash, which favored Sogroya (OR 0.1, 95% CI 0.04-0.27, p < 0.00001). Additionally, IGF-1 SDS was significantly higher in the Sogroya group than in the Norditropin group (MD 0.25, 95% CI 0.02-0.48, p = 0.03). Furthermore, the overall score of the TSQM-9 questionnaire, which includes three domains: convenience, effectiveness, and satisfaction, was significantly higher in the Sogroya group compared to the Norditropin group (OR 6.36, 95% CI 3.92-8.8, p < 0.00001). CONCLUSION: Norditropin and Sogroya showed comparable efficacy and safety profiles, except for the prevalence of rash in the Norditropin group, and Sogroya has higher satisfaction among adults. More high-quality studies with more patients are required to confirm these results.

Clinical and nutritional correlates of bacterial diarrhoea aetiology in young children: a secondary cross-sectional analysis of the ABCD trial.

OBJECTIVE: The objective was to assess the association between nutritional and clinical characteristics and quantitative PCR (qPCR)-diagnosis of bacterial diarrhoea in a multicentre cohort of children under 2 years of age with moderate to severe diarrhoea (MSD). DESIGN: A secondary cross-sectional analysis of baseline data collected from the AntiBiotics for Children with Diarrhoea trial (NCT03130114). PATIENTS: Children with MSD (defined as >3 loose stools within 24 hours and presenting with at least one of the following: some/severe dehydration, moderate acute malnutrition (MAM) or severe stunting) enrolled in the ABCD trial and collected stool sample. STUDY PERIOD: June 2017-July 2019. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Likely bacterial aetiology of diarrhoea. Secondary outcomes included specific diarrhoea aetiology. RESULTS: A total of 6692 children with MSD had qPCR results available and 28% had likely bacterial diarrhoea aetiology. Compared with children with severe stunting, children with MAM (adjusted OR (aOR) (95% CI) 1.56 (1.18 to 2.08)), some/severe dehydration (aOR (95% CI) 1.66 (1.25 to 2.22)) or both (aOR (95% CI) 2.21 (1.61 to 3.06)), had higher odds of having likely bacterial diarrhoea aetiology. Similar trends were noted for stable toxin-enterotoxigenic Escherichia coli aetiology. Clinical correlates including fever and prolonged duration of diarrhoea were not associated with likely bacterial aetiology; children with more than six stools in the previous 24 hours had higher odds of likely bacterial diarrhoea (aOR (95% CI) 1.20 (1.05 to 1.36)) compared with those with fewer stools. CONCLUSION: The presence of MAM, dehydration or high stool frequency may be helpful in identifying children with MSD who might benefit from antibiotics.
