[PMID: 35903295 PMCID: PMC9325485 DOI: 10.1155/2022/7461958] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Accepted: 06/22/2022] [Indexed: 12/02/2022]
Abstract
Objective Growth hormone deficiency (GHD) refers to the complete or partial lack of pituitary growth hormone synthesis and secretion. This study is aimed at investigating the efficacy of vitamin D and recombinant human growth hormone (rhGH) in children with GHD. Methods A total of 100 children with GHD at our hospital were included between 1st January 2018 and 31st October 2020. The patients were divided into a study group (n = 70, received vitamin D combined with rhGH) and a control group (n = 30, received rhGH). The growth and development (bone age, growth rate, and height), bone metabolism (bone alkaline phosphatase (BAP), β-collagen degradation product (β-CTX), osteocalcin (OC), and amino-terminal propeptide type I procollagen (PINP)), insulin-like growth factor 1 (IGF-1), ghrelin, and adverse reactions in the two groups were measured before and 12 months after treatment. Results There were no significant differences in the bone age, growth rate, and height between the two groups before treatment. After 12 months of treatment, the bone age, growth rate, and height of the study group were significantly higher than those of the control group. After 12 months of treatment, the levels of serum BAP, PINP, and OC in the study group were significantly higher than those in the control group, while the levels of β-CTX in the study group were significantly lower than those in the control group. The serum IGF-1 level in the study group was significantly higher than that in the control group, while the ghrelin level in the study group was lower. There was no significant difference in the incidence of adverse reactions between the two groups. Conclusion Combined rhGH and vitamin D treatment can promote growth and development, improve bone metabolism, and regulate IGF-1 and ghrelin levels.

Abstract
Acromegaly presents with an enigmatic range of symptoms and comorbidities caused by chronic and progressive growth hormone elevations, commonly due to endocrinologic hypersecretion from a pituitary gland tumor. Comprehensive national acromegaly databases have been appearing over the years, allowing for international comparisons of data, although still presenting varying prevalence and incidence rates. Lack of large-scale analysis in geographical and ethnic differences in clinical presentation and management requires further research. Assessment of current and novel predictors of responsiveness to distinct therapy can lead to multilevel categorization of patients, allowing integration into new clinical guidelines and reduction of increased morbidity and mortality associated with acromegaly. This review compares current data from epidemiological studies and assesses the present-day application of prognostic factors in medical practice, the reality of precision therapy, as well as its future prospects in acromegaly, with a special focus on its relevance to the South Korean population.

Abstract
Growth hormone (GH) deficiency is caused by congenital or acquired causes and occurs in childhood or adulthood. GH replacement therapy brings benefits to body composition, exercise capacity, skeletal health, cardiovascular outcomes, and quality of life. Before initiating GH replacement, GH deficiency should be confirmed through proper stimulation tests, and in cases with proven genetic causes or structural lesions, repeated GH stimulation testing is not necessary. The dosing regimen of GH replacement therapy should be individualized, with the goal of minimizing side effects and maximizing clinical improvements. The Korean Endocrine Society and the Korean Society of Pediatric Endocrinology have developed a position statement on the diagnosis and treatment of GH deficiency. This position statement is based on a systematic review of evidence and expert opinions.

Abstract
OBJECTIVE Hybrid Fc-fused rhGH (GX-H9) is a long-acting recombinant human growth hormone (GH) under clinical development for both adults and children with GH deficiency (GHD). We compared the safety, pharmacokinetics and pharmacodynamics of weekly and every other week (EOW) dosages of GX-H9 with those of daily GH administration in adult GHD (AGHD) patients. DESIGN This was a randomized, open-label, active-controlled and dose-escalation study conducted in 16 endocrinology centers in Europe and Korea. METHODS Forty-five AGHD patients with or without prior GH treatment were enrolled. Patients with prior GH treatments were required to have received the last GH administration at least 1 month prior to randomization. Subjects were sequentially assigned to treatment groups. Fifteen subjects were enrolled to each treatment group and randomly assigned to receive either GX-H9 or Genotropin (4:1 ratio). GX-H9 dosage regimens for Groups 1, 2 and 3 were 0.1 mg/kg weekly, 0.3 mg/kg EOW and 0.2 mg/kg EOW, respectively. All Genotropin-assigned subjects received 6 µg/kg Genotropin, regardless of treatment group. Main outcome analyses included measurements of serum insulin-like growth factor 1 (IGF-I), safety, pharmacokinetics, pharmacodynamics and immunogenicity. RESULTS Mean GX-H9 peak and total exposure increased with an increase in dose after a single-dose administration. The mean IGF-I response was sustained above baseline over the intended dose interval of 168 h for the weekly and 336 h for the EOW GX-H9 groups. Safety profiles and immunogenicity were not different across the treatment groups and with Genotropin. CONCLUSIONS GX-H9 has the potential for up to twice-monthly administration.

Abstract
BACKGROUND PATRO Children is an ongoing observational, longitudinal, non-interventional, global post-marketing surveillance study, which is investigating the long-term safety and effectiveness of Omnitrope®, a somatropin biosimilar to Genotropin®, in children with growth disturbances. The primary endpoint of PATRO Children is long-term safety and the secondary endpoint is effectiveness, which is assessed by analysing auxological data such as height (HSDS) and height velocity (HVSDS) standard deviation scores. Here, we report the data from the Italian interim analysis of PATRO Children data up to August 2015. METHODS PATRO Children is enrolling children who are diagnosed with conditions of short stature requiring GH treatment and are receiving Omnitrope®. Adverse events (AEs) are assessed in all Omnitrope®-treated patients. Height is evaluated yearly to near-adult (final) height, and is herein reported as HSDS; height velocity is also assessed and reported as a standard deviation score (HVSDS). RESULTS Up to August 2015, a total of 186 patients (mean age 10.2 years, 57.5 % males) were enrolled :156 [84 %] had growth hormone deficiency, 12 [6.5 %] were born small for gestational age, seven [3.8 %] had Prader-Willi syndrome, one [0.5 %] had Turner syndrome and one [0.5 %] had chronic renal insufficiency; seven [3.8 %] patients had other indication profiles. The mean treatment duration with Omnitrope® was 28.1 ± 19.1 months. AEs were reported in 35.6 % of patients and included headache, pyrexia, arthralgia, abdominal pain, leg and/or arm pain and increased blood creatine phosphokinase. Two serious AEs in two patients were thought to be drug-related; one patient experienced a minimal increase in a known residual craniopharyngioma, and another a gait disturbance with worsening of walking difficulties. Similar to investigational studies, Omnitrope® treatment was associated with improvements in both HSDS and HVSDS. CONCLUSIONS Omnitrope® appears to be well tolerated and effective for the treatment of a wide range of paediatric indications, which is consistent with the outcomes from controlled clinical trials. These results need to be interpreted with caution until the data from the global PATRO Children study are available.

[PMID: 26843473 DOI: 10.1016/j.ghir.2015.12.009] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2015] [Revised: 12/17/2015] [Accepted: 12/31/2015] [Indexed: 11/20/2022]
Abstract
OBJECTIVES The catabolic phase following burn injuries increases caloric imbalance and results in substantial weight loss because of hypermetabolism; energy expenditures as high as twice the normal limit have been documented during the first 3 weeks. Furthermore, the wound size and healing duration seem to be related to the length of stay in the intensive care unit, which results in the loss of muscle mass, the so-called sarcopenia; weakness; and physical frailty. Possible therapeutic strategies include exercises, use of anabolic steroids, or replacement with human growth hormone (hGH). To determine the clinical effects of hGH on sarcopenia after burn injuries, we compared patients who received subcutaneous hGH injections during rehabilitation with control patients who received placebo treatment. METHODS A total of 33 patients with third degree burn injuries covering a total body surface area of >20% were randomly divided into a test group (n=18), which received 2-mg injections of sustained release hGH (SR-hGH) weekly for 3 months during rehabilitation, and a control group (n=15), which followed the same rehabilitation protocol with placebo injections. Muscular strength, cardiopulmonary function, body composition, and body weight were measured at baseline and 1 and 3 months after SR-hGH or placebo administration. RESULTS The mean age of patients was 37.67 ± 7.64 years in the SR-hGH group and 37.22 ± 8.19 years in the control group, while the interval between injury and SR-hGH or placebo injection was 123.7 ± 53.6 and 126.6 ± 43.5 days, respectively. The oxygen consumption at the lactate threshold, maximum oxygen consumption, lean body mass, knee extensor peak torque, and insulin-like growth factor 1 (IGF-1) and adiponectin levels were significantly higher in the SR-hGH group than in the control group at 3 months. There were no differences in the body weight, systolic and diastolic blood pressure (BP), bone mineral content, percentage body fat, and burn scar characteristics between groups. CONCLUSION Our results suggest that SR-hGH treatment during the rehabilitation of adult burn survivors positively affects physical fitness levels, muscle power, and metabolic processes, although further confirmation through research of metabolic pathways in burn survivors is required.

Abstract
CONTEXT NNC0195-0092 is a reversible, albumin-binding GH derivative, developed for once-weekly administration. OBJECTIVES The objective of the study was to evaluate safety, local tolerability, pharmacodynamics, and pharmacokinetics of multiple, once-weekly doses of NNC0195-0092, compared with daily GH. DESIGN AND SETTING This was a phase 1, randomized, open-label, active-controlled, multiple-dose, dose-escalation trial. PATIENTS Thirty-four GH-treated adult subjects (male, n = 25) with GH deficiency participated in the study. INTERVENTIONS AND MAIN OUTCOME MEASURES Subjects were sequentially assigned into four cohorts of eight subjects, randomized within each cohort (3:1) to once-weekly NNC0195-0092 (n = 6) for 4 weeks (0.02, 0.04, 0.08, and 0.12 mg/kg) or daily injections of Norditropin NordiFlex (n = 2) for 4 weeks with a dose replicating the pretrial dose of somatropin. A safety assessment was performed prior to initiating treatment at the next dose level of NNC0195-0092. Daily GH treatment was discontinued 14 days before the trial start. Blood samples were drawn for assessment of safety, pharmacokinetics, pharmacodynamics (IGF-1 and IGF-binding protein-3) profiles, and immunogenicity studies. RESULTS Numbers of adverse events were similar at the dose levels of 0.02, 0.04, and 0.08 mg/kg NNC0195-0092 vs daily injections of Norditropin NordiFlex, whereas the number of adverse events was greater at the highest dose level of NNC0195-0092 (0.12 mg/kg). NNC0195-0092 (area under the curve[0-168h]) and peak plasma concentration) increased in a dose-dependent manner, and a dose-dependent increase in IGF-1 levels was observed. IGF-1 profiles were elevated for at least 1 week, and for the 0.02-mg/kg and 0.04-mg/kg NNC0195-0092 doses, the observed IGF-1 levels were similar to the levels for the active control group. CONCLUSION Four once-weekly doses of NNC0195-0092 (dose range 0.02-0.12 mg/kg) administered to adult patients with GH deficiency were well tolerated, and IGF-1 profiles were consistent with a once-weekly treatment profile. No clinically significant safety and tolerability signals causally related to NNC0195-0092 were identified, nor were any immunogenicity concerns revealed.

Abstract
Microbial exopolysaccharides (EPS) have found outstanding medical applications since the mid-20th century, with the first clinical trials on dextran solutions as plasma expanders. Other EPS entered medicine firstly as conventional pharmaceutical excipients (e.g., xanthan - as suspension stabilizer, or pullulan - in capsules and oral care products). Polysaccharides, initially obtained from plant or animal sources, became easily available for a wide range of applications, especially when they were commercially produced by microbial fermentation. Alginates are used as anti-reflux, dental impressions, or as matrix for tablets. Hyaluronic acid and derivatives are used in surgery, arthritis treatment, or wound healing. Bacterial cellulose is applied in wound dressings or scaffolds for tissue engineering. The development of drug controlled-release systems and of micro- and nanoparticulated ones, has opened a new era of medical applications for biopolymers. EPS and their derivatives are well-suited potentially non-toxic, biodegradable drug carriers. Such systems concern rating and targeting of controlled release. Their large area of applications is explained by the available manifold series of derivatives, whose useful properties can be thereby controlled. From matrix inclusion to conjugates, different systems have been designed to solubilize, and to assure stable transport in the body, target accumulation and variable rate-release of a drug substance. From controlled drug delivery, EPS potential applications expanded to vaccine adjuvants and diagnostic imaging systems. Other potential applications are related to the bioactive (immunomodulator, antitumor, antiviral) characteristics of EPS. The numerous potential applications still wait to be developed into commercial pharmaceuticals and medical devices. Based on previous and recent results in important medical-pharmaceutical domains, one can undoubtedly state that EPS medical applications have a broad future ahead.
