The Cost-Effectiveness of Intermediate-Acting,Long-Acting,Ultralong-Acting,and Biosimilar Insulins for Type 1 Diabetes Mellitus: A Systematic Review

ObjectivesThe incidence of type 1 diabetes mellitus is increasing every year requiring substantial expenditure on treatment and complications. A systematic review was conducted on the cost-effectiveness of insulin formulations, including ultralong-, long-, or intermediate-acting insulin, and their biosimilar insulin equivalents.MethodsMEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, HTA, and NHS EED were searched from inception to June 11, 2021. Cost-effectiveness and cost-utility analyses were included if insulin formulations in adults (≥ 16 years) with type 1 diabetes mellitus were evaluated. Two reviewers independently screened titles, abstracts, and full-text articles, extracted study data, and appraised their quality using the Drummond 10-item checklist. Costs were converted to 2020 US dollars adjusting for inflation and purchasing power parity across currencies.ResultsA total of 27 studies were included. Incremental cost-effectiveness ratios ranged widely across the studies. All pairwise comparisons (11 of 11, 100%) found that ultralong-acting insulin was cost-effective compared with other long-acting insulins, including a long-acting biosimilar. Most pairwise comparisons (24 of 27, 89%) concluded that long-acting insulin was cost-effective compared with intermediate-acting insulin. Few studies compared long-acting insulins with one another.ConclusionsLong-acting insulin may be cost-effective compared with intermediate-acting insulin. Future studies should directly compare biosimilar options and long-acting insulin options and evaluate the long-term consequences of ultralong-acting insulins.

Adherence to and persistence with antidiabetic medications and associations with clinical and economic outcomes in people with type 2 diabetes mellitus: A systematic literature review

We designed a systematic literature review to identify available evidence on adherence to and persistence with antidiabetic medication in people with type 2 diabetes (T2D). Electronic screening and congress searches identified real-world noninterventional studies (published between 2010 and October 2020) reporting estimates of adherence to and persistence with antidiabetic medication in adults with T2D, and associations with glycaemic control, microvascular and/or macrovascular complications, hospitalizations and healthcare costs. Ninety-two relevant studies were identified, the majority of which were retrospective and reported US data. The proportions of patients considered adherent (median [range] 51.2% [9.4%-84.3%]) or persistent (median [range] 47.7% [16.9%-94.0%]) varied widely across studies. Multiple studies reported an association between greater adherence/persistence and greater reductions in glycated haemoglobin levels. Better adherence/persistence was associated with fewer microvascular and/or macrovascular outcomes, although there was little consistency across studies in terms of which outcomes were improved. More adherent and more persistent patients were typically less likely to be hospitalized or to have emergency department visits/admissions and spent fewer days in hospital annually than less adherent/persistent patients. Greater adherence and persistence were generally associated with lower hospitalization costs, higher pharmacy costs and lower or budget-neutral total healthcare costs compared with lower adherence/persistence. In conclusion, better adherence and persistence in people with T2D is associated with lower rates of microvascular and/or macrovascular outcomes and inpatient hospitalization, and lower or budget-neutral total healthcare expenditure. Education and treatment strategies to address suboptimal adherence and persistence are needed to improve clinical and economic outcomes.

The effects of grape seed extract on glycemic control,serum lipoproteins,inflammation, and body weight: A systematic review and meta‐analysis of randomized controlled trials

The aim of this systematic review and meta‐analysis was to analyze the effects of grape seed extract (GSE) on glycemic control and serum lipoproteins, inflammation and body weight. Two independent authors systematically searched online databases including EMBASE, Scopus, PubMed, Cochrane Library, and Web of Science from inception until May 30, 2019. Cochrane Collaboration risk of bias tool was applied to assess the methodological quality of included trials. The heterogeneity among the included studies was assessed using Cochrane's Q test and I‐square (I²) statistic. Data were pooled using a random‐effects model and weighted mean difference (WMD) was considered as the overall effect size. Fifty trials were included in this meta‐analysis. Pooling effect sizes from studies demonstrated a significant decrease in fasting plasma glucose (FPG) (WMD): ?2.01; 95% confidence interval (CI): ?3.14, ?0.86), total cholesterol (TC; WMD: ?6.03; 95% CI: ?9.71, ?2.35), low‐density lipoprotein (LDL) cholesterol (WMD: ?4.97; 95% CI: ?8.37, ?1.57), triglycerides (WMD: ?6.55; 95% CI: ?9.28, ?3.83), and C‐reactive protein (CRP) concentrations (WMD: ?0.81; 95% CI: ?1.25, ?0.38) following GSE therapy. Grape seed did not influence HbA1c, HDL cholesterol levels, and anthropometric measurements. This meta‐analysis demonstrated that GSE intake significantly reduced FPG, TC, LDL cholesterol, triglycerides, and CRP levels.     

补肾化浊方联合粪菌移植对来曲唑诱导的多囊卵巢综合征大鼠生殖、代谢功能及相关炎症因子的影响

目的以肠道微生态为切入点探讨补肾化浊方联合粪菌移植治疗多囊卵巢综合征(PCOS)潜在机制。方法将30只6周龄SD大鼠随机分为空白组、模型组、中药组、粪菌移植组、中药+粪菌移植组,每组6只。来曲唑1 mg/(kg d)灌胃51 d,第22日起,中药组加灌补肾化浊方21.7 g/(kg d),粪菌移植组加灌新鲜粪便2 g/(kg d),中药+粪菌移植组加灌补肾化浊方21.7 g/(kg d)和新鲜粪便2 g/(kg d),连续30 d,另设空白组。干预结束后,腹主动脉取血检测大鼠血清性激素、空腹胰岛素(FINS)、空腹血糖(FPG),ELISA检测大鼠血清白细胞介素(IL)-18、肿瘤坏死因子-α(TNF-α)水平,HE染色观察大鼠卵巢形态学变化。结果与空白组比较,模型组大鼠卵巢呈多囊样改变,体质量、睾酮、黄体生成素(LH)/促卵泡激素(FSH)、FPG、HOMA-IR、IL-18、TNF-α水平均明显升高(P<0.01,P<0.001);与模型组比较,中药+粪菌移植组可显著改善上述指标(P<0.05,P<0.01,P<0.001),中药组可显著改善除TNF-α外各项指标(P<0.05,P<0.01),粪菌移植组可显著降低PCOS大鼠LH/FSH、IL-18水平(P<0.01,P<0.001);在降低IL-18水平方面,中药+粪菌移植组作用显著优于中药组(P<0.01)。结论中药联合粪菌移植可显著改善PCOS大鼠生殖和代谢功能,改善慢性炎症状态。
