Clinical Effect Analysis of Different Doses of Creatine Phosphate Sodium Combined with Immunoglobulin in the Treatment of Pediatric Viral Myocarditis

The purpose of this paper was to unravel the clinical effect analysis of different doses of creatine phosphate sodium (CPS) combined with immunoglobulin in the treatment of pediatric viral myocarditis (VMC). One hundred and twenty children with VMC were recruited and randomized into three groups (40 patients each). Group I received 1.0 g of CPS dissolved in 100 mL of 5% glucose injection intravenously 1 time/day; group II received 1.25 g of CPS dissolved in 125 mL of 5% glucose injection intravenously 1 time/day; group III received 1.5 g of CPS dissolved in 150 mL of 5% glucose injection intravenously 1 time/day; then all three groups were treated with combined use of immunoglobulin (300-400 mg/day) intravenously once a day; and all three groups were treated for 14 days. The clinical efficacy, cardiac function, serum inflammatory factor levels, immune function, and the occurrence of drug toxicity and adverse effects of the children in the three groups were compared after 14 days of treatment. All three groups achieved better therapeutic effects after treatment, in which the effective rate of the Group II and Group III was notably higher versus the Group I. Lower levels of cTnI, CK-MB, LDH, AST, IL-18, IL-6, IFN-γ, and LVEDD and higher CD3+, CD4+, and CD4+/CD8+, FS, and LVEF values were noted in the Group II and Group III versus the Group I, and the results were more pronounced in the high-dose group. The liver and kidney functions of the children in the three groups before and after treatment did not show any significant changes and the incidence of adverse reactions during the treatment period was low in all three groups. Children with VMC can be treated with high-dose CPS in combination with immunoglobulin, which can improve their cardiac function and immune function and reduce the inflammatory response with good overall therapeutic efficacy and fewer adverse effects.

Effects of different doses of long-acting growth hormone in treating children with growth hormone deficiency

BACKGROUND

With the improvement of economy and living standards, the attention paid to short stature in children has been increasingly highlighted. Numerous causes can lead to short stature in children, among which growth hormone deficiency (GHD) is a significant factor.

AIM

To investigate the long-term efficacy and safety of different doses of long-acting polyethylene glycol recombinant human growth hormone (PEG-rhGH) in the treatment of GHD in children.

METHODS

We selected 44 pediatric patients diagnosed with GHD who were treated at Wuhu First People's Hospital from 2014 to 2018. Total 23 patients were administered a high dose of long-acting PEG-rhGH at 0.2 mg/kg subcutaneously each week, forming the high-dose group. Meanwhile, 21 patients were given a lower dose of long-acting PEG-rhGH at 0.14 mg/kg subcutaneously each week, establishing the low-dose Group. The total treatment period was 2 years, during which we monitored the patients' height, annual growth velocity (GV), height standard deviation score (HtSDS), chronological age (CA), bone age (BA), and serum levels of insulin-like growth factor-1 (IGF-1) and insulin-like growth factor-binding protein-3 (IGFBP-3) before treatment and at 6 mo, 1 year, and 2 years after treatment initiation. We also monitored thyroid function, fasting plasma glucose, fasting insulin, and other side effects. Furthermore, we calculated the homeostatic model assessment for insulin resistance.

RESULTS

After 1 year of treatment, the GV, HtSDS, IGF-1, BA, and IGFBP-3 in both groups significantly improved compared to the pre-treatment levels (P < 0.05). Moreover, when comparing GV, HtSDS, IGF-1, BA, and IGFBP-3 between the two groups, there were no statistically significant differences either before or after the treatment (P > 0.05). During the treatment intervals of 0-1.0 years and 1.0-2.0 years, both patient groups experienced a slowdown in GV and a decline in HtSDS improvement (P < 0.05).

CONCLUSION

The use of PEG-rhGH in treating GHD patients was confirmed to be effective, with similar outcomes observed in both the high-dose group and low-dose groups, and no significant differences in the main side effects.

[Efficacy of different doses of magnesium isoglycyrrhizinate in the treatment of chronic liver disease with elevated ALT: a meta-analysis]

Objective: To investigate the efficacy and safety profile of different doses of magnesium isoglycyrrhizinate in the treatment of chronic liver disease with elevated alanine aminotransferase (ALT). Methods: Computer retrieval of literature was conducted in the CNKI, Wanfang, and PubMed databases from the establishment of the databases until February 2023. The Cochrane risk of bias assessment tool was used to evaluate the quality of the included literature after screening the literature and extracting the data. RevMan 5.4 and Stata 15.0 software were used to analyze the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), total effective rate, and incidence of adverse events. Results: Finally, 10 articles were selected, including a total of 1 522 cases. All the included studies were of good quality and at low risk of bias. Meta-analysis results showed that compared with 100 mg/d magnesium isoglycyrrhizinate injection, 200 mg/d magnesium isoglycyrrhizinate injection had significantly reduced patients' ALT [MD = -30.73, 95% confidence interval (CI): -52.52 ~ -8.94, Z = 2.76, P = 0.006; I (2) = 98%, P < 0.001], AST (MD = -34.30, 95% CI: -57.78 ~ -10.82, Z = 2.86, P = 0.004; I (2) = 99%, P < 0.001) and TBil (MD = -15.37, 95% CI: -27.66 ~ -3.09), Z = 2.45, P = 0.01; I (2) = 98%, P < 0.001) levels. The total effective rate reported in seven articles showed no heterogeneity among the studies (I (2) = 0.0%, P = 0.98). The total effective rate was higher in 200 mg/d magnesium isoglycyrrhizinate injection than that of 100 mg/d magnesium isoglycyrrhizinate injection (OR = 3.49, 95% CI: 2.05 ~ 5.95, Z = 4.59, P < 0.001), and there was no statistically significant difference in adverse reactions. Conclusion: 200 mg/d magnesium isoglycyrrhizinate injection can more rapidly and effectively improve the levels of ALT, AST, and TBil in patients with chronic liver disease, with an increased total effective rate and a good safety profile.

A randomized phase II, open-label and multicenter study of combination regimens of bortezomib at two doses by subcutaneous injection for newly diagnosed multiple myeloma patients

PURPOSE

Combinations of bortezomib (Velcade), cyclophosphamide and dexamethasone have shown significant efficacy and safety for patients of newly diagnosed multiple myeloma (NDMM). In this study, we compared the efficacy and safety of modified VCD regimens with novel changes in bortezomib dose and schedule for NDMM.

METHODS

Eighty-five NDMM patients from multiple centers were randomly assigned to a high-dose (1.6 mg/m²) (group A) or a low-dose (1.3 mg/m²) (group B) bortezomib, administrated on days 1, 6, 11, and 16 subcutaneously in a 4-week cycle for nine cycles, combined with 40 mg dexamethasone on bortezomib days and cyclophosphamide 300 mg/m² on days 1-3 intravenously.

RESULTS

After four cycles, complete response (CR) or better in group A (43.6%) was higher than that in group B (12.8%) (P = 0.002). During induction, for patients with R-ISS stage III, the CR or better rate in group A was superior to that in group B (P = 0.01). Of patients < 65, the CR or better rate of group A was superior to that of group B (P = 0.004). Rapid onset of CR occurred in group A (P < 0.01). Meanwhile, rate of 3-4 diarrhea was higher in group A (P = 0.03), which caused higher rate of dose reduction for patients ≥ 65 (P = 0.041). No significant difference between the two groups in PFS and OS.

CONCLUSIONS

The studied high-dose VCD as induction regimen had an improved CR rate, especially in patients < 65 or with R-ISS stage III, and is feasible for young and high-risk patients. Trial registration ClinicalTrials.gov: NCT02086942.
