Growth Hormone Treatment and Papilledema: A Prospective Pilot Study

Hormonal therapy for impaired growth due to pediatric-onset inflammatory bowel disease: a systematic review and meta-analysis with trial sequential analysis

INTRODUCTION

Inflammatory bowel diseases (IBDs) have an increasing incidence in the pediatric population. The dysabsorptive effects of this condition often lead to a decrease in linear growth. However, the effectiveness and safety of growth hormone (GH) therapy in this population is still a topic of debate, with studies showing conflicting results.

CONTENT

MEDLINE, Embase, and Cochrane Library databases were systematically searched according to the PRISMA guidelines. All experimental studies featuring children with IBD receiving GH therapy were included. In addition, a trial sequential analysis (TSA) was conducted to determine the sample size required for each outcome. The prospective registry was carried out under protocol CRD42024563079. The total data set comprised eight studies involving 127 patients with IBD, 78 (61.41 %) of whom received GH therapy, with a mean follow-up duration of 1.3 years. A statistically significant effect of GH was found in increasing the height standard deviation score (HtSDS) of children with IBD (standardized mean difference - SMD=1.07; CI=0.58, 1.56; p<0.0001). When comparing children who received GH with controls, no significant improvement in HtSDS was observed (SMD=0.18; CI=-0.73, 1.08; p=0.70). However, meta-regression analysis indicated that a longer follow-up was associated with a greater improvement in the HtSDS (p=0.04). Regarding height velocity (HV), a significant increase was found when comparing measurements before and after the initiation of hormone therapy (mean difference - MD=4.09; CI=2.58, 5.60; p<0.0001). An increase in HV was also noted in children receiving GH compared to the control group (MD=4.47; CI=2.03, 6.90; p=0.0003). No significant changes in the Pediatric Crohn's Disease Activity Index (PCDAI) were detected, comparing values before and after the start of treatment (MD=-10.09; CI=-22.29, 2.10; p=0.10). The overall prevalence of any adverse effect was estimated at 15.51 % (95 % CI: 2.32-58.70 %). Most common reaction was itching at injection sites. TSA indicated a low risk of overestimating or underestimating the intervention's effect on the analyzed outcomes.

SUMMARY

Our study points to the effectiveness and safety of GH therapy in children with IBD and growth impairment.

OUTLOOK

Further randomized controlled trials (RCT) with standardized methodologies and extended follow-up periods are necessary to confirm these findings.

A Case of Idiopathic Intracranial Hypertension with Papilledema Secondary to Recombinant Human Growth Hormone Treatment

Purpose: To report a child with idiopathic intracranial hypertension secondary to recombinant human growth hormone treatment.Case summary: An 11-year-old girl presented with blurred vision in both eyes starting 6 weeks earlier. She did not have any underlying disease and her body mass index was normal. She had started recombinant human growth hormone injections for idiopathic short stature 3 months earlier. The best corrected visual acuity was 20/25 in both eyes. Fundoscopy revealed bilateral disc edema with peripapillary hemorrhage and increased tortuosity of the retinal vessels. Bilateral enlargement of the blind spot was found on automated visual field examination. Magnetic resonance imaging and venography of the brain showed no evidence of structural or vascular lesions related to increased intracranial pressure. A lumbar puncture showed an elevated opening pressure of 26 cmH2O with normal cerebrospinal fluid constituents. She was diagnosed with growth hormone-related idiopathic intracranial hypertension and it was recommended that the growth hormone injection be discontinued and oral acetazolamide started. After 4 weeks of treatment, the optic disc edema and visual field defect improved. At the 2-year follow-up, she had a normal visual field with a normal optic nerve in both eyes.Conclusions: Ophthalmologists should be aware of the clinical features and treatment of idiopathic intracranial hypertension secondary to recombinant human growth hormone treatment, which is a very rare, vision-threatening complication. Complete neuro-ophthalmological examinations should be performed immediately in children complaining of visual disturbances or headache during treatment with recombinant human growth hormone.

Management of Short Stature: Use of Growth Hormone in GH-Deficient and non-GH-Deficient Conditions

Growth hormone (GH) is an important driver for somatic growth and increase in height in children. The development of recombinant human GH has greatly increased its availability, and hence the potential for its use and abuse. GH therapy should only be offered to patients with established and approved indications. Common pediatric indications for treatment include growth hormone deficiency, Turner syndrome, Prader-Willi syndrome, small for gestational age, chronic renal insufficiency, and idiopathic short stature. Before initiating treatment, the family should be counseled about the treatment goals, costs, and possible adverse effects from the treatment. It is important for patients to have realistic expectations from the treatment. The dose of GH should be individualized for the indication and will require titration in each patient based on response to the treatment and the adverse effects. Overall, GH has a good safety record. However, GH treatment has many potential and real adverse effects that need to be considered and monitored during treatment. Recently, safety concerns regarding the long-term effect of GH therapy on cardiovascular morbidity have come under scrutiny.
