Abstract
Approximately 80% of children with short stature are classified as having Idiopathic Short Stature (ISS). While growth hormone (GH) treatment received FDA approval in the United States in 2003, its long-term impact on final height remains debated. Other treatments, like aromatase inhibitors, metformin, and insulin-like growth factor-1 (IGF-1), have been explored, but there is no established standard treatment for ISS. In South Korea and other Asian countries, East Asian Traditional Medicine (EATM) is sometimes employed by parents to potentially enhance their children's height growth, often involving herbal medicines. One such product, Astragalus membranaceus extract mixture HT042, claims to promote height growth in children and has gained approval from the Korean Food and Drug Administration (KFDA). Research suggests that HT042 supplementation can increase height growth in children without skeletal maturation, possibly by elevating serum IGF-1 and IGF-binding protein-3 levels. Preclinical studies also indicate the potential benefits of natural products, including of EATM therapies for ISS. The purpose of this review is to offer an overview of bone growth factors related to ISS and to investigate the potential of natural products, including herbal preparations, as alternative treatments for managing ISS symptoms, based on their known efficacy in in vivo studies.

Abstract
BACKGROUND Herbal medicines have been used for a long time to treat idiopathic short stature (ISS) in children in East Asian countries. The aim of this study was to analyze the cost-effectiveness of 5 herbal medicines frequently used in clinical settings for children with ISS based on medical records. METHODS Patients with ISS who had been prescribed a 60-day supply of herbal medicines in 1 Korean medicine hospital were included in this analysis. Their height and height percentile were measured before and after treatment within 6-months. The average cost-effectiveness ratios (ACERs) of 5 herbal medicines for height (cm) and height percentile were calculated for boys and girls, respectively. RESULTS The ACERs per 1 cm height growth were USD 56.2 (Naesohwajung-Tang), USD 74.8 (Ogapi-Growth decoction), USD 86.6 (Gamcho-Growth decoction), USD 94.6 (Gwakhyangjeonggi-San plus Yukmijihwang-Tang), and USD 113.8 (Boyang-Growth decoction). The ACERs per 1 percentile height growth were USD 205 (Naesohwajung-Tang), USD 293 (Ogapi-Growth decoction), USD 470 (Gamcho-Growth decoction), USD 949 (Boyang-Growth decoction), and USD 1051 (Gwakhyangjeonggi-San plus Yukmijihwang-Tang). CONCLUSION Herbal medicine might be a potential economical alternative treatment for ISS.

Abstract
Background Korean medicine (KM) interventions are attractive for children with idiopathic short stature (ISS). We investigated the real-world clinical practice patterns of KM doctors in ISS treatment. Methods The survey targeted KM doctors who have treated patients with ISS in KM clinical settings for >3 years. We included questions on the diagnosis and treatment patterns, effects, cost, and opinions of doctors on KM treatment for ISS. A frequency analysis was performed. Results There were 58 respondents, and “heights of parents” (n = 57, 98.3%), “height, weight, and growth rate of child” (n = 55, 94.8%), and “amount of meals, digestive function” (n = 52, 89.7%) were frequently used as indicators for diagnosis and treatment. The most frequently used KM interventions were “herbal medicine” (n = 58, 100%), “acupuncture” (n = 49, 84.5%), “moxibustion” (n = 38, 65.5%), “dry cupping” (n = 26, 44.8%), and “physiotherapy” (n = 22, 37.9%). Herbal medicines were generally prescribed to tonify the spleen or kidney, and the most frequently used individual herbs were Acanthopanacis cortex, Astragali Radix, and Cervi parvum cornu. The most common acupuncture points were ST36, GB34, SP6, EX-LE5, and LI4. Conclusions This study showed the use of KM for ISS in real-world clinical settings. In the future, well-designed clinical studies to verify the effect of KM treatment on ISS based on real-world clinical practice patterns should be actively performed.

Effectiveness and Safety of Combination Therapy with Herbal Medicine and Growth Hormone Compared to Growth Hormone Monotherapy for Short Stature Children: A Systematic Review and Meta-Analysis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:5725258. [PMID: 35982997 PMCID: PMC9381207 DOI: 10.1155/2022/5725258] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Accepted: 07/19/2022] [Indexed: 11/18/2022]
Abstract
Introduction Herbal medicines (HM) and growth hormones (GH) are widely used to treat short stature (SS) in children. This systematic review aimed to evaluate the effectiveness and safety of combination therapy with HM and GH (CHG) compared to those of GH monotherapy (GHM) in children with SS. Methods We searched 17 electronic databases from inception to 1 April 2021. Only randomized controlled trials (RCTs) were included. Two authors independently performed the selection and quality assessment of the included studies using Cochrane Handbook criteria. Relative risk (RR) was used to measure dichotomous outcomes with a 95% confidence interval (CI). Mean difference (MD) or standard MD (SMD) was used to measure continuous outcomes with a 95% CI. Results Seven RCTs involving 455 participants with SS were included. Standard deviations in height (MD = 0.31, 95% CI: 0.24–0.38, p < 0.00001), and insulin-like growth factor binding protein-3 (MD = 1.39, 95% CI: 0.93–1.85, p < 0.00001) were significantly higher in the CHG group than in the GHM group. Growth velocity (MD = 1.82, 95% CI: 1.34–2.31, p < 0.00001) and insulin-like growth factor-1 (MD = 61.85, 95% CI: 55.80–67.90, p < 0.00001) were significantly higher in the CHG group. Adverse events were significantly lower in the CHG group (risk ratio: 0.10, 95% CI: 0.02–0.54, p = 0.007). However, the level of evidence was low. Conclusions CHG demonstrated significantly better efficacy than GHM for treating SS, with a low incidence of adverse events. However, since the level of evidence is low, methodologically standardized RCTs are required to verify these results.

Abstract
Background Idiopathic short stature (ISS) is a common problem in children and causes many economic and social burdens. In Asian countries, East Asian traditional medicine (EATM) therapies are widely used for children with ISS. In this study, we compared and ranked various EATM therapies for the treatment of pediatric ISS using network meta-analysis. Methods Randomized controlled trials that evaluated various EATMs for pediatric ISS were found through searching 14 electronic databases. The primary outcome was growth velocity (GV). The comparative effectiveness of the treatments was ranked based on the surface under the cumulative ranking curve (SUCRA) and the risk of bias was assessed. The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations approach. Results Fourteen studies comprising 1,066 participants were included. HM plus GH showed statistically significant superiority over other EATM therapies including acupuncture (weighted mean difference (WMD) 3.20 cm, 95% confidence interval (CI) 0.40 to 5.99) and HM (WMD 3.70 cm, 95% CI 1.41 to 5.99) for improving GV per year, although there was no difference compared with GH alone (WMD 1.18 cm, 95% CI -0.27 to 2.63). SUCRA indicated that HM plus GH was the most effective therapy for increasing GV, followed by GH, HM plus acupressure, and HM. No serious adverse events were reported. Conclusion For the treatment of ISS, HM plus GH might have a large beneficial effect and might be a better option than EATM therapies and GH alone. However, more long-term, high-quality trials are warranted to confirm the findings. Protocol registration PROSPERO (https://www.crd.york.ac.uk/prospero/), CRD42020187160.

Molecules 2021; 26:molecules26247579. [PMID: 34946658 PMCID: PMC8706552 DOI: 10.3390/molecules26247579] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 12/06/2021] [Accepted: 12/10/2021] [Indexed: 11/16/2022] Open
Abstract
Yukmijihwang-tang (YJ) has been used to treat diabetes mellitus, renal disorders, and cognitive impairment in traditional medicine. This study aimed to evaluate the anti-osteoporotic effect of YJ on ovariectomy (OVX)-induced bone loss in a rat and receptor activator of nuclear factor kappa-B ligand (RANKL)-mediated osteoclast differentiation in bone marrow macrophages (BMMs). YJ reduced the formation of tartrate-resistant acid phosphatase (TRAP)-positive multinucleated cells (MNCs) in an osteoclast/osteoblast co-culture system by regulating the ratio of RANKL/osteoprotegerin (OPG) by osteoblasts. Overall, YJ reduced TRAP-positive cell formation and TRAP activity and F-actin ring formation. Analysis of the underlying mechanisms indicated that YJ inhibited the activation of the nuclear factor of activated T cell cytoplasmic 1 (NFATc1) and c-Fos, resulting in the suppression of osteoclast differentiation-related genes such as TRAP, ATPase, H+ transporting, lysosomal 38 kDa, V0 subunit d2, osteoclast-associated receptor, osteoclast-stimulatory transmembrane protein, dendritic cell-specific transmembrane protein, matrix metalloproteinase-9, cathepsin K, and calcitonin receptor. YJ also inhibited the nuclear translocation of NFATc1. Additionally, YJ markedly inhibited RANKL-induced phosphorylation of signaling pathways activated in the early stages of osteoclast differentiation including the p38, JNK, ERK, and NF-κB. Consistent with these in vitro results, the YJ-administered group showed considerably attenuated bone loss in the OVX-mediated rat model. These results provide promising evidence for the potential novel therapeutic application of YJ for bone diseases such as osteoporosis.

Effects of Astragalus Extract Mixture HT042 on Circulating IGF-1 Level and Growth Hormone Axis in Rats. CHILDREN 2021; 8:children8110975. [PMID: 34828688 PMCID: PMC8622163 DOI: 10.3390/children8110975] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/09/2021] [Revised: 10/05/2021] [Accepted: 10/20/2021] [Indexed: 11/16/2022]
Abstract
Astragalus extract mixture HT042 is a standardized functional food granted by the Korean FDA for promoting “Children’s Height Growth”. In this study, we determined whether HT042 affects circulatory Insulin-like growth factor-1 (IGF-1) after administration and investigated whether Growth hormone (GH), Growth hormone-releasing hormone receptor (GHRH-R), and Growth hormone secretagogue receptor (GHS-R) mRNAs are expressed in the pituitary, and whether Growth hormone-releasing hormone (GHRH) and Somatostatin (SST) are expressed in the hypothalamus. We also evaluated the growth effect of HT042 on endochondral bone formation. Male Sprague-Dawley rats in the control and HT042 groups were orally administered a single dose of the control and HT042, respectively, and those in the recombinant human GH (rhGH) group were subcutaneously injected with rhGH. Tetracycline was injected intraperitoneally 72 h prior to sacrifice to decide endochondral bone formation. To determine the endocrine or paracrine/autocrine mechanism, we evaluated the expression of local BMP-2 and IGF-1, an immunohistochemical study after HT042 administration. It was confirmed that the growth-promoting effect of HT042 can be contributed to the increase in serum IGF-1, which can be stimulated by GH secretion. Administration of HT042 modulated the activity of GHRH-R and GHR-S in the pituitary gland and promoted GH secretion, thereby changing longitudinal growth through GH/IGF-1 mediation. Results for GHRH and SST expression demonstrated that the hypothalamus can be influenced and mediated by HT042 through a complex neuroendocrine regulatory system. In addition, it was confirmed by oral administration for 10 days that HT042 increased bone formation in cartilage, which is important for height growth. The effect of HT042 could be owing to upregulation of local Bone morphogenetic protein-2 (BMP-2) and IGF-1 expression in the growth plate, which could be regarded as a GH-dependent autocrine/paracrine pathway, as well as circulatory IGF-1.

Abstract
BACKGROUND There are many East Asian traditional medicine (EATM) therapies that are widely used and effective for idiopathic short stature (ISS) in children. However, the comparative effectiveness of these therapies remains unclear. We describe the methods that will be used to comparatively evaluate the efficacy and safety of EATM therapies for the treatment of pediatric ISS. METHODS AND ANALYSIS Fourteen electronic English, Korean, Chinese, and Japanese databases will be searched up to August 2020 for relevant randomized controlled trials of various EATMs for the treatment of pediatric ISS, without language or publication status restrictions. The primary outcome will be growth-related anthropometric indicators, and acceptability, measured through drop-outs that occur during treatment for any reason. We will conduct a pairwise meta-analysis for direct comparisons if multiple studies use the same types of intervention, comparison, and outcome measure. A frequentist network meta-analysis will be performed to summarize the available direct and indirect evidence regarding various EATM options for pediatric ISS. The risk of bias for the included studies will be evaluated using the Cochrane Collaboration's risk of bias tool. CONCLUSIONS The findings of this review will provide evidence for the comparative effectiveness and ranks of current EATMs and help to inform clinical practitioners, patients, and policy makers in decision making. ETHICS AND DISSEMINATION Ethical approval is not required because individual patient data are not included. The findings of this systematic review will be disseminated through a peer-reviewed publication or conference presentations.

Abstract
Excessive intake of fluoride inhibits bone growth in both humans and animals. It is unknown whether fluoride acts directly on the growth plate to inhibit longitudinal bone growth, and its mechanism of action has not been elucidated. In this study, we used an organ culture system and SW1353 cells to evaluate the effects of fluoride on endochondral ossification. Neonatal rat metatarsal bones were dissected and cultured with or without fluoride for 7 days. The total length and width of the metatarsal rudiments and the length of the calcification zone were measured. Chondrocyte proliferation, differentiation, and apoptosis were analyzed by immunohistochemistry and TUNEL assay in sectioned bones. The apoptosis was detected by flow cytometry, and the expression of apoptosis-related proteins Bax, Bcl-2, and Caspase-3 were detected by western blotting in SW1353 cells. Linear measurements demonstrated that fluoride induced a biphasic effect on longitudinal bone growth in organ culture, with a significant growth inhibition at a high concentration (10-4 M) and a stimulatory action at low concentration (10-6 M) of fluoride. Histomorphometrical analysis of growth plate from fluoride-exposed metatarsal rudiments showed a significant reduction in the height of the proliferative and hypertrophic chondrocyte zones. Analysis of the Col2α1 and Col10α1 expression by immunohistochemistry revealed fluoride-suppressed metatarsal growth plate chondrocyte proliferation and differentiation. In addition, fluoride increased the number of apoptotic chondrocytes in the metatarsal growth plate. Western blotting showed an up-regulated expression of Caspase-3 and Bax and down-regulated expression of anti-apoptotic protein Bcl-2 after treatment with 5 × 10-4 M fluoride in SW1353 cells. Our findings indicated that fluoride inhibited longitudinal bone growth by acting directly at the growth plate in cultured neonatal rat metatarsal bones. Such growth inhibition was mediated by suppressing proliferation and differentiation, increasing apoptosis of resting chondrocytes and causing premature cell senescence in the growth plate.

Abstract
The aim of this study was to investigate the effects of administration of a mixture of Humulus japonicus (MH) on longitudinal bone growth in normal Sprague Dawley (SD) rats. We measured the femur and tibia length, growth plate area, proliferation of chondrocytes, and expression of insulin-like growth factor-1 (IGF-I) and IGF binding protein-3 (IGFBP-3), and Janus kinase 2 (JAK2)/signal transducer and activator of transcription 5 (STAT5) phosphorylation after dietary administration of MH in SD rats for four weeks. The nose–tail length gain and length of femur and tibia increased significantly in the group that received MH for a period of four weeks. We performed H&E staining and Bromodeoxyuridine/5-Bromo-2′-Deoxyuridine (BrdU) staining to examine the effect of dietary administration of MH on the growth plate and the proliferation of chondrocytes and found that MH stimulated the proliferation of chondrocytes and contributed to increased growth plate height during the process of longitudinal bone growth. In addition, serum levels of IGF-1 and IGFBP-3 and expression of IGF-1 and IGFBP-3 mRNAs in the liver and bone were increased, and phosphorylation of JAK2/STAT5 in the liver was increased in the MH groups. Based on these results, we suggest that the effect of MH on longitudinal bone growth is mediated by increased JAK2/STAT5-induced IGF-1 production.

Abstract
Eleutherococcus extract mixture (EEM) is an herbal mixture of dried stem of Eleutherococcus sessiliflorus and germinated barley, which has been highly effective, in previous screening and among the traditional medicines to tonify innate qi and acquired qi, respectively. In this study, we investigate the effects of EEM on endochondral bone formation. Female adolescent rats were given EEM, growth hormone or vehicle for 10 days. Tetracycline was intraperitoneally injected to light the fluorescent band 72 h before sacrifice to determine endochondral bone formation. In order to evaluate endocrine or paracrine/autocrine mechanisms, expressions of insulin-like growth factor 1 (IGF1), insulin-like growth factor binding protein 3 (IGFBP3), or bone morphogenetic protein 2 (BMP2) were evaluated after EEM administration in liver or growth plate (GP). EEM oral administration significantly increased endochondral bone formation and proliferative and hypertrophic zonal heights of tibial GP. EEM also upregulated hepatic IGF1 and IGFBP3 mRNA expressions, and IGF1 and BMP2 expressions in GP. Taken together, EEM increases endochondral bone formation through stimulating proliferation and hypertrophy with upregulation of hepatic IGF1 and IGFBP3 expressions. Considering immunohistochemical studies, the effect of EEM may be due to increased local IGF1 and BMP2 expression in GP, which may be considered growth hormone (GH)-dependent endocrine and autocrine/paracrine pathways.

Dai G, Wang D, Dong H. Effects of recombinant human growth hormone on protein malnutrition and IGF-1 and IL-2 gene expression levels in chronic nephrotic syndrome. Exp Ther Med 2018; 15:4167-4172. [PMID: 29725365 PMCID: PMC5920232 DOI: 10.3892/etm.2018.5953] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2017] [Accepted: 12/11/2017] [Indexed: 11/05/2022] Open
Abstract
The aim of the study was to investigate the effects of recombinant human growth hormone on protein malnutrition and insulin-like growth factor-1 (IGF-1) and interleukin-2 (IL-2) gene expressions in chronic nephrotic syndrome. Eighty patients with chronic nephrotic syndrome were admitted to our hospital. The patients were included in the study period from January 2015 to December 2016 and were divided into two groups (40 cases in each group) according to the random number method. All the patients enrolled received symptomatic and supportive treatment. The observation group was injected subcutaneously with recombinant human growth hormone, while the control group was treated with Shenyankangfu tablets. The recovery time of the clinical symptoms, change in serum protein, caloric intake and protein metabolism after intervention were compared between the two groups. Changes in serum cystatin C, IGF-1 and IL-2 before intervention, and at 1 week, 1 month and 3 months after intervention were detected, and the adverse reactions in the two groups were observed during the treatment. After intervention, the improvement time of proteinuria, hypoproteinemia, edema and hyperlipidemia in the observation group was significantly shorter than that in the control group (P<0.05). The expression of transferrin, pre-albumin, albumin and total protein in the observation group was significantly superior increased compared to those in the observation group prior to intervention and the control group after intervention (P<0.05). In addition the caloric intake, protein intake and urea nitrogen survival rate in the observation group were significantly superior to those in the observation group prior to intervention and the control group after intervention (P<0.05). At 1 week, 1 month and 3 months after intervention, the levels of serum cystatin C, IGF-1 and IL-2 in the observation group were markedly obviously lower than those in the control group during the same period (P<0.05). The total proportion of allergy, systemic pruritus, nausea and vomiting, abdominal distension and abdominal pain in the observation group was obviously lower than that in the control group (P<0.05). Compared with the traditional Chinese medicine Shenyankangfu tablets applied in the control group, the recombinant human growth hormone used for patients with chronic nephrotic syndrome can improve the clinical symptoms more quickly, regulate the protein metabolism and reduce the inflammatory response in the body, which also has fewer adverse reactions and higher safety.
