Efficacy and safety among second-generation and other basal insulins in adult patients with type 1 diabetes: a systematic review and network meta-analysis

Safety, efficacy, and cost-effectiveness of insulin degludec U100 versus insulin glargine U300 in adults with type 1 diabetes: a systematic review and indirect treatment comparison

BACKGROUND

Clinical differences between degludec U100 (Deg-100) and glargine U300 (Gla-300) in type 1 diabetes (T1D) were unknown.

AIM

To indirectly compare the safety, efficacy, and cost-effectiveness between Deg-100 and Gla-300 in T1D adults via systematic review.

METHOD

Medline, the Cochrane Library, ClinicalTrials.gov, and Google Scholar were searched (October 2021). Randomized controlled trials comparing Deg-100 or Gla-300 vs. glargine U100 in T1D adults (follow-up ≥ 12 weeks) were selected and analyzed using a frequentist network meta-analysis. Cost-effectiveness analysis (CEA) was conducted over a 1-year time horizon from societal perspectives.

RESULTS

Nine trials were included. Efficacy analysis suggested that Deg-100 was non-inferior to Gla-300 in reducing HbA_1c (MD 0.03 [95% CI - 0.09 to 0.15]; P = 0.60), FPG (MD - 1.12 [- 2.19 to - 0.04]; P = 0.04), and pre-breakfast SMBG (MD - 0.71 [- 1.46 to 0.03]; P = 0.06). Safety analysis suggested that Deg-100 appeared to have lower rates of both severe (HR 0.44 [0.25-0.78]; P = 0.005) and nocturnal severe (HR 0.19 [0.08-0.44]; P < 0.001) hypoglycemia, with lower total (MD - 0.07 [- 0.13 to - 0.01]; P = 0.02) and basal (MD - 0.08 [- 0.12 to - 0.04]; P < 0.001) insulin doses compared with Gla-300. No significant differences were observed for other hypoglycemia outcomes, adverse events, serious adverse events, bolus insulin dose, and body weight. The CEA showed that Deg-100 appeared to be a dominant treatment in Japan (+ 0.0283 QALYs, ¥26,266 [$228] per patient) and the United States (+ 0.0267 QALYs, $986 per patient).

CONCLUSION

Low-certainty indirect evidence suggested that Deg-100 appeared to have a favorable reduction in rates of severe hypoglycemia and more cost-effective compared with Gla-300 in T1D adults.

Efficacy and Safety of the Chinese Patent Medicine Yuquan Pill on Type 2 Diabetes Mellitus Patients: A Systematic Review and Meta-Analysis

Background

Yuquan Pill (YQP), a Chinese patent medicine for the treatment of diabetes, is widely used in the treatment of diabetes and its complications in China. However, the efficacy of YQP on type 2 diabetes mellitus (T2DM) has not been completely assessed. The aim of this study is to evaluate the efficacy and safety of YQP in the treatment of T2DM.

Materials and Methods

We systematically searched 9 databases for specific keywords from inception to Oct 2021. We included randomized controlled trials (RCTs) involving YQP in the treatment of T2DM without language limitation. The study conformed to the Cochrane Handbook and Review Manager software was used for data analysis. The weighted mean differences (WMDs) and 95% confidence intervals (CIs) were used to measure treatment effects.

Results

The final analysis included 10 publications. Analysis showed that the combination of YQP and conventional treatment was more effective than conventional treatment alone with regard to the levels of fasting blood glucose (WMD = −0.83; 95% CI [−1.01,−0.66]; p < 0.00001), two-hour postprandial glucose (WMD = −1.40; 95% CI [−1.49,−1.31]; p < 0.00001), glycosylated hemoglobin (WMD = −0.87; 95% CI [−1.26, −0.49]; p < 0.00001), total cholesterol (WMD = −0.50; 95% CI [−0.61, −0.39]; p < 0.00001), c-reactive protein (WMD = −0.58; 95%CI [−0.88, −0.28]; p=0.0002), and overall effective rate (RR = 1.21; 95% CI [1.12, 1.31]; p < 0.00001).

Conclusion

Evidence suggested that YQP might improve glucose and lipid metabolism and inflammation in patients with T2DM. Serious adverse events were not reported. The quality of the evidence analyzed was low and therefore our results should be interpreted with caution. More high-quality RCTs are now needed to verify these findings.
