ObjectiveReal-time continuous glucose monitoring (RT-CGM) provides detailed information on glucose patterns and trends, thus allowing the patients to manage their diabetes more effectively.DesignThe aim of this study was to explore the potential beneficial effects of the use of RT-CGM on diabetes management compared with self blood glucose measurement (SBGM) in patients with type 1 diabetes mellitus (T1DM), by means of a systematic review and meta-analysis of randomized controlled trials (RCTs).MethodsMEDLINE, EMBASE, and the Cochrane Library were searched through by two independent investigators for RCTs concerning the use of RT-CGM in patients with T1DM. Only studies with a similar insulin regimen in the experimental and control groups were included in the analysis.ResultsSeven RCTs (n=948) met the inclusion criteria. Combined data from all studies showed better HbA1c reduction in subjects using RT-CGM compared with those using SBGM (mean difference (MD) −0.25; 95% confidence interval (95% CI): from −0.34 to −0.17; P<0.001). Patients treated with insulin pump and RT-CGM had a lower HbA1c level compared with subjects managed with insulin pump and SBGM (four RCTs, n=497; MD −0.26; 95% CI: from −0.43 to −0.10; P=0.002). The benefits of applying RT-CGM were not associated with an increasing rate of major hypoglycemic episodes. The use of RT-CGM for over 60–70% of time was associated with a significant lowering of HbA1c.ConclusionsRT-CGM is more beneficial than SBGM in reducing HbA1c in patients with type 1 diabetes. Further studies are needed to evaluate the efficacy of this system in the pediatric population, especially in very young children.

  Background: Several clinical trials have tested the safety profile of sodium-glucose co-transport inhibitors’ (SGLTis) in adult type 1 diabetes mellitus (T1DM) patients. However, no systematic review has yet compared its variation between large and low dose SGLTis. Henceforth, a review protocol is proposed here to review it. Methods: Different electronic databases will be searched for randomized-controlled trials (published in the English language) studying the above objective, irrespective of their publication date. After selecting the eligible trials, their data on the study design, population characteristics, compared interventions, and outcomes of interest will be extracted. Then, utilizing the Cochrane tool, each trial's risk of selection bias, detection bias, performance bias, attrition bias, reporting bias, and other bias will be judged. Next, depending on clinical heterogeneity among the trials, a random-effect or fixed-effect model meta-analysis will be used to compare the respective outcomes. Via the Chi2 and I2 statistics, the statistical inconsistency among the trials will be estimated. When this is substantial, subgroup analysis will follow. Publication bias will be evaluated by funnel plots and Egger’s test. A sensitivity analysis will be done to check different assumptions. If a quantitative juxtaposition is not possible, a narrative reporting will ensue. Conclusion: The proposed study will perform a dose-wise juxtaposition of the safety profile of SGLTis in insulin-treated T1DM patients.

Background and Purpose: The dapagliflozin’s safety profile in insulin-treated adult type-1 diabetes mellites (T1DM) patients remains poorly explored. Therefore, this systematic review and meta-analysis compared the risk of all-cause side effects, study discontinuation of participants due to side effects, urinary tract infection (UTI), diabetic ketoacidosis, and hypoglycemia between dapagliflozin 10 mg and dapagliflozin 5 mg, dapagliflozin 10 mg and placebo, and dapagliflozin 5 mg and placebo.Materials and Methods: Parallel-arm randomized controlled trials juxtaposing the above outcomes between the afore-mentioned interventions were eligible for inclusion in this study and were searched in PubMed, Embase, and Scopus. Utilizing the Cochrane tool, the risk of bias was assessed in the recruited trials. Finally, by random-effect meta-analysis, each outcome was compared among the above interventions, and the risk ratio was estimated.Results: Four trials of varying length (1-52 weeks) sourcing data from almost 1760 participants from about 32 nations were reviewed. Overall, the trials had a low or unclear risk of bias, and only one was at a high risk of bias.  Compared to the placebo, the risk of side effects was higher in those treated with dapagliflozin 5 mg (RR=1.10; 95% CI=1.02-1.18; p=0.014; I2=0%). UTI risk was less with the 10mg dapagliflozin than its lower dose (RR=0.50; 95% CI=0.32-0.79; p-value=0.003; I2=0%). All the remaining comparisons were statistically not significantly different between the juxtaposed intervention pairs.Conclusion: In contrast to placebo, dapagliflozin 5mg increased the risk of overall adversities in insulin-treated type-1 diabetes, and dapagliflozin 10 mg had a reduced risk of UTI than its 5mg preparation.
