COVID-19 and diabetes mellitus: A need for prudence in elderly patients from a pooled analysis.

ABSTRACT: OBJECTIVE:The objective of this study was to evaluate the pooled estimate of diabetes prevalence in young (<50 years) versus elderly (>50 years) COVID-19 cohorts. METHODS:Studies published between December-2019 and March-2020 reporting demographic and clinical characteristics of COVID-19 cases were identified. A total of 11 studies included accounting for 2084 COVID-19 patients. RESULTS:The overall prevalence of diabetes in COVID-19 patients with a mean age>50 years was 13.2%, whereas studies with relatively younger patients (mean age <50 years) had a pooled prevalence of 9.0% CONCLUSION: The overall prevalence of diabetes in COVID-19 patients was found to be 13.2% with studies including relatively elderly patients showing higher rates of diabetes. The intermingled effects of diabetes with other cardiovascular comorbidities warrant age-specific outcomes data including the impact of ongoing antidiabetic treatment.

Project description:IntroductionThe aim of this analysis was to characterize the safety and tolerability of empagliflozin in patients with type 2 diabetes mellitus (T2DM) who were randomized to empagliflozin (10/25 mg) or placebo in clinical trials.MethodsPooled data from 20 trials were analyzed for patients with T2DM treated with empagliflozin 10 mg (n = 4858), empagliflozin 25 mg (n = 5057), or placebo (n = 4904). The dataset comprised 15 randomized phase I-III trials, an extension trial and dose escalation studies. Adverse events (AEs) were assessed descriptively in participants who took ≥ 1 dose of study drug. AE incidence rates per 100 patient-years were calculated to adjust for differences in drug exposure between trials.ResultsTotal exposure was 16,480 and 7857 patient-years in the pooled empagliflozin 10/25 mg and placebo groups, respectively. The incidence of any AEs, AEs leading to treatment discontinuation, severe AEs, and serious AEs was similar across groups. The frequency of serious AEs requiring hospitalization was 18.6% for the empagliflozin 10/25 mg group and 21.3% for the placebo group. The empagliflozin 10/25 mg group was not associated with a higher rate of confirmed hypoglycemia versus placebo, except in patients co-administered insulin and/or a sulfonylurea (31.5% vs. 30.2%, respectively). The incidence of events consistent with urinary tract infections (UTI) was also similar for the empagliflozin 10/25 mg group versus placebo (9.27 vs. 9.70/100 patient-years, respectively). History of UTI was identified as a risk factor for UTI during treatment. Events consistent with genital infections occurred more frequently with empagliflozin 10/25 mg than placebo (3.54 vs. 0.95/100 patient-years, respectively). The frequency of AEs consistent with volume depletion was similar across groups, but higher with empagliflozin 10/25 mg than placebo in patients aged 75 to < 85 years and those on loop diuretics at baseline.ConclusionThis comprehensive analysis confirms that both empagliflozin 10 mg and 25 mg are well tolerated in patients with T2DM, reinforcing the established clinical safety profile of empagliflozin.

Project description:Clinical trial registrationwww.ClinicalTrials.gov, identifier: NCT04365634.ContextDiabetes mellitus was associated with increased severity and mortality of disease in COVID-19 pneumonia. So far the effect of type 2 diabetes (T2DM) or hyperglycemia on the immune system among COVID-19 disease has remained unclear.ObjectiveWe aim to explore the clinical and immunological features of type 2 diabetes mellitus (T2DM) among COVID-19 patients.Design and methodsIn this retrospective study, the clinical and immunological characteristics of 306 hospitalized confirmed COVID-19 patients (including 129 diabetic and 177 non-diabetic patients) were analyzed. The serum concentrations of laboratory parameters including cytokines and numbers of immune cells were measured and compared between diabetic and non-diabetic groups.ResultsCompared with non-diabetic group, diabetic cases more frequently had lymphopenia and hyperglycemia, with higher levels of urea nitrogen, myoglobin, D-dimer and ferritin. Diabetic cases indicated the obviously elevated mortality and the higher levels of cytokines IL-2R, IL-6, IL-8, IL-10, and TNF-α, as well as the distinctly reduced Th1/Th2 cytokines ratios compared with non-diabetic cases. The longitudinal assays showed that compared to that at week 1, the levels of IL-6 and IL-8 were significantly elevated at week 2 after admission in non-survivors of diabetic cases, whereas there were greatly reductions from week 1 to week 2 in survivors of diabetic cases. Compared with survival diabetic patients, non-survival diabetic cases displayed distinct higher serum concentrations of IL-2R, IL-6, IL-8, IL-10, TNF-α, and lower Th1/Th2 cytokines ratios at week 2. Samples from a subset of participants were evaluated by flow cytometry for the immune cells. The counts of peripheral total T lymphocytes, CD4+ T cells, CD8+ T cells and NK cells were markedly lower in diabetic cases than in non-diabetic cases. The non-survivors showed the markedly declined counts of CD8+ T cells and NK cells than survivors.ConclusionThe elevated cytokines, imbalance of Th1/Th2 cytokines ratios and reduced of peripheral numbers of CD8+ T cells and NK cells might contribute to the pathogenic mechanisms of high mortality of COVID-19 patients with T2DM.
