Recombinant growth hormone therapy in a girl with Costello syndrome: a 4-year observation.

ABSTRACT: Costello syndrome is a rare syndrome of multiple congenital anomalies. The typical clinical traits include dysmorphic craniofacial features, skin hyperpigmentation and excess, feeding difficulties leading to severe postnatal growth retardation, short stature, joint hypermobility, and delayed psychomotor development. Additionally, Costello syndrome may present with an increased incidence of congenital heart disease, hypertrophic cardiomyopathy, and increased risk of both benign and malignant tumors. Furthermore, cases of patients with endocrine disorders such as adrenal insufficiency and endogenous growth hormone deficiency have also been documented.We present a patient with Costello syndrome who has been successfully treated with recombinant human growth hormone (rhGH) for almost 4 years.The possibility of growth hormone (GH) treatment can be considered in cases of documented GH deficiency in patients with Costello syndrome, but only under close oncologic and cardiologic supervision.

Project description:Abstract Backgrounds Craniosynostosis syndrome has a variety of causes, one of which is an autosomal dominant disorder associated with FGFR1 or FGFR2 gene mutation known as Pfeiffer syndrome (PS; OMIM 101600). It is known that PS is clinically diagnosed, not genetic judgment. PS is divided into three subtypes depending on severity of specific phenotypes. Patients with PS type 1 are broad thumbs and great toes, brachydactyly or syndactyly. They have widely spaced eyes, midface hypoplasia and dental abnormalities but short stature is not typical phenotype of PS. We report the patient who were clinically diagnosed PS with short stature because of growth hormone deficiency (GHD). Case Report: A 4 years 7 month-old girl presented with a short stature below the 3rd percentile. She was born at 40 weeks of gestation with a birth weight of 2.9 kg. Her perinatal and neonatal histories were unremarkable. Her parents are non-consanguineous and her mother had micro- pituitary adenoma. She has healthy younger brother who aged 9 months old. In physical examination, height was 91.1 cm (-3.92 SDS), weight was 15.5 kg (-1.15 SDS). Wide thumb and great toes on both sides of her are observed. At the time of admission, bone age was advanced, measured 7 years. There were no specific findings other than a decrease in IGF-1 level (108.24 ng/ml) and increase in prolactin level (27.26 ng/ml) on the basic endocrine examination. The growth hormone (GH) induced stimulation test was performed after admission. She underwent GH induced stimulation test with combinations of 2 stimulants to assess GH secretion: levodopa 150 mg and arginine 0.5 g/kg. The peak GH level was 7.41 ng/ml in levodopa test and 5.58 ng/ml after 30 minutes’ response to arginine. She was diagnosed as a partial GHD defined by peak GH between 5 and 10 ng/ml in both test. There were no findings in karyotyping and chromosomal microarray. As a result of targeted panel sequencing of 233 genes related to hereditary short stature, c.2398dupT, a pathogenic variant that had not been previously reported in the FGFR2 gene, was observed in a heterozygous form as the cause of short stature. Subsequently, recombinant human GH has been administered in units of 0.1 per day according to her weight. The height was increased from 93.6 cm (SDS) in 4 years 10 months old to 98 cm in 5 years 2 months. Any side effects or adverse reactions were not observed during the treatment period. Conclusion It is suggested that a growth hormone test be performed for Pfeiffer syndrome patients with short stature. GH may help growth in patients with positive in the test.

Project description:BackgroundShort stature is the most consistent characteristic feature of Turner syndrome (TS). To improve final heights of children with TS effectively, it is important to provide them with early and appropriate treatment using growth hormone (GH). The objective of this study was to assess the efficacy and safety of a new recombinant human GH, Growtropin®-II (DA-3002, Dong-A ST Co., Ltd) versus a comparator (Genotropin®, Pfizer Inc.) for Korean children with TS.MethodsThis open-label, active-controlled, parallel-group, randomized controlled phase III trial was conducted at 11 hospitals in Korea. Eligible patients (n = 58) were randomized to two groups: 1) DA-3002 group (administrated with DA-3002 at 0.14 IU [0.0450-0.050 mg] /kg/day); and 2) comparator group (administrated with the comparator at 0.14 IU [0.0450-0.050 mg] /kg/day).ResultsThe change from baseline in annualized height velocity (HV) after a 52-week treatment period was 4.15 ± 0.30 cm/year in the DA-3002 group and 4.34 ± 0.29 cm/year in the comparator group. The lower bound of 95% two-sided confidence interval for group difference in the change of annualized HV (- 1.02) satisfied the non-inferiority margin (- 1.5). The change in height standard deviation score (HtSDS) at 52-week was 0.70 ± 0.23 for the DA-3002 group and 0.66 ± 0.39 for the comparator group, showing no significant (p = 0.685) difference between the two groups. The change of skeletal maturity defined as change in bone age/change in chronological age between the two groups was not significantly different (1.25 ± 0.58 for the DA-3002 group and 1.47 ± 0.45 for the comparator group, p = 0.134). Changes from baseline in serum insulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding protein-3 (IGFBP-3) after 52 weeks of treatment did not differ significantly between the two groups (p = 0.565 and p = 0.388, respectively) either. The occurrence of adverse events was not statistically different between groups.ConclusionsThis study demonstrates that the efficacy and safety of GH treatment with DA-3002 in children with TS are comparable with those of the comparator. It is expected to analysis the long-term effect of DA-3002 on the increase of final adult height in children with TS and possible late-onset complications in the future.Trial registrationThe study was registered at ClinicalTrials.gov. ClinicalTrials.gov identifier: NCT01813630 (19/03/2013).

Project description:Recombinant human GH (rhGH) therapy in Prader-Willi syndrome (PWS) has been used by the medical community and advocated by parental support groups since its approval in the United States in 2000 and in Europe in 2001. Its use in PWS represents a unique therapeutic challenge that includes treating individuals with cognitive disability, varied therapeutic goals that are not focused exclusively on increased height, and concerns about potential life-threatening adverse events.The aim of the study was to formulate recommendations for the use of rhGH in children and adult patients with PWS.We performed a systematic review of the clinical evidence in the pediatric population, including randomized controlled trials, comparative observational studies, and long-term studies (>3.5 y). Adult studies included randomized controlled trials of rhGH treatment for ? 6 months and uncontrolled trials. Safety data were obtained from case reports, clinical trials, and pharmaceutical registries.Forty-three international experts and stakeholders followed clinical practice guideline development recommendations outlined by the AGREE Collaboration (www.agreetrust.org). Evidence was synthesized and graded using a comprehensive multicriteria methodology (EVIDEM) (http://bit.ly.PWGHIN).Following a multidisciplinary evaluation, preferably by experts, rhGH treatment should be considered for patients with genetically confirmed PWS in conjunction with dietary, environmental, and lifestyle interventions. Cognitive impairment should not be a barrier to treatment, and informed consent/assent should include benefit/risk information. Exclusion criteria should include severe obesity, uncontrolled diabetes mellitus, untreated severe obstructive sleep apnea, active cancer, or psychosis. Clinical outcome priorities should vary depending upon age and the presence of physical, mental, and social disability, and treatment should be continued for as long as demonstrated benefits outweigh the risks.
