Anti-SARS-CoV-2 Antibody Level Is Associated with a History of COVID-19 Infection and mRNA Vaccination in Patients with Diabetes.

Type 2 diabetes mellitus (T2DM) is associated with higher severity and mortality in SARS-CoV-2 infections. Vaccination has been encouraged to boost immunity and prevent these unfortunate outcomes. Few studies have evaluated antibody levels after COVID-19 vaccination in patients with T2DM. Therefore, we examined the vaccination status and anti-SARS-CoV-2 antibody levels to identify the factors that affect the antibody levels in patients with T2DM. This cross-sectional study was conducted at the Dr. Hasan Sadikin Hospital and Bandung Kiwari Hospital, Bandung, West Java, Indonesia, between October and November 2022. Adult participants with and without T2DM were tested for SARS-CoV-2 antibodies using a point-of-care quantitative immunochromatographic assay. We enrolled 289 participants: 201 participants with T2DM and 88 participants without T2DM. The T2DM participants had a lower vaccination rate compared with the non-T2DM participants. However, no significant differences in antibody levels were observed between the two groups. Higher antibody levels among the T2DM participants were associated with mRNA vaccination and a history of COVID-19 illness. The lower antibody response observed among the T2DM participants with chronic obstructive pulmonary disease suggests that such patients may need antibody level measurement and an additional booster vaccine.

Diabetes and Mortality among Patients with Chronic Kidney Disease and COVID-19: A Systematic Review, Meta-analysis, and Meta-regression.

Introduction: Patients with kidney disease and COVID-19, whether on hemodialysis (HD) or not, have a higher risk of contracting COVID-19 accompanied by a higher mortality rate due to suppressed immune functions. Diabetes, one of the ubiquitous etiology of kidney disease, is also associated with a composite of poor outcomes. Methods: Meta-analysis and meta-regression of 13 articles on COVID-19 patients with chronic kidney disease, with information on diabetes and mortality were performed using Review Manager 5.4 and OpenMetaAnalyst. Results: The meta-analysis of a pooled subject of 18,822 patients showed that the presence of diabetes in CKD patients with COVID-19 was associated with an increased risk of mortality (RR 1.41 (1.15, 1.72); P < 0.001; I2 70%, P < 0.001). Subgroup analysis showed that diabetes was not associated with mortality in the HD group (RR 1.27 (1.06, 1.54); P = 0.01; I2 0%, P = 0.70) but showed a significant association in the non-HD group (RR 1.66 (1.59, 1.73); P < 0.001; I2 85%, P < 0.001). Male gender (P = 0.070) contributed to the effect size differences (age: P < 0.001; hypertension: P = 0.007; CVD: P < 0.001; lung disease: P < 0.001). Conclusions: Diabetes was associated with higher mortality risk among CKD patients, primarily those who did not need RRT.

Antibody response following SARS-CoV-2 vaccination among patients with type 2 diabetes mellitus: A systematic review.

BACKGROUND AND AIM: DM patients' antibody response after the COVID-19 vaccine is still unknown amid the COVID-19 vaccination rollout. This study aimed to explore the SARS-CoV-2 antibody response or seropositivity among DM patients following the COVID-19 vaccine administration. METHODS: We performed a systematic review of the literature consisting of observational or cross-sectional studies, which reported the antibody serology or seropositivity among DM patients by following the PRISMA 2020 guidelines. RESULTS: Eight studies with a total of 64468 patients were identified, and 5156 (7.9%) of them had diabetes. Most studies showed that antibody response and seropositivity in DM patients were lower than healthy population after one until four weeks following full COVID-19 vaccination dose. CONCLUSION: The antibody response and seropositivity after the COVID-19 vaccine in DM patients were lower than in healthy subjects. Therefore, DM patients are expected to receive vaccines according to the dose and schedule appropriately and might be prioritized to receive vaccine boosters.

In-hospital use of statins is associated with a reduced risk of mortality in coronavirus-2019 (COVID-19): systematic review and meta-analysis.

BACKGROUND AND AIMS: The idea of treating COVID-19 with statins is biologically plausible, although it is still controversial. The systematic review and meta-analysis aimed to address the association between the use of statins and risk of mortality in patients with COVID-19. METHODS: Several electronic databases, including PubMed, SCOPUS, EuropePMC, and the Cochrane Central Register of Controlled Trials, with relevant keywords up to 11 November 2020, were used to perform a systematic literature search. This study included research papers containing samples of adult COVID-19 patients who had data on statin use and recorded mortality as their outcome of interest. Risk estimates of mortality in statin users versus non-statin users were pooled across studies using inverse-variance weighted DerSimonian-Laird random-effect models. RESULTS: Thirteen studies with a total of 52,122 patients were included in the final qualitative and quantitative analysis. Eight studies reported in-hospital use of statins; meanwhile, the remaining studies reported pre-admission use of statins. In-hospital use of statin was associated with a reduced risk of mortality (RR 0.54, 95% CI 0.50-0.58, p < 0.00001; I2: 0%, p = 0.87), while pre-admission use of statin was not associated with mortality (RR 1.18, 95% CI 0.79-1.77, p = 0.415; I2: 68.6%, p = 0.013). The funnel plot for the association between the use of statins and mortality were asymmetrical. CONCLUSION: This meta-analysis showed that in-hospital use of statins was associated with a reduced risk of mortality in patients with COVID-19.

The Association Between Chronic Kidney Disease and New Onset Renal Replacement Therapy on the Outcome of COVID-19 Patients: A Meta-analysis.

OBJECTIVE: The aim of the study was to evaluate the association between chronic kidney disease (CKD) and new onset renal replacement therapy (RRT) with the outcome of Coronavirus Disease 2019 (COVID-19) in patients. METHODOLOGY: A systematic literature search from several databases was performed on studies that assessed CKD, use of RRT, and the outcome of COVID-19. The composite of poor outcome consisted of mortality, severe COVID-19, acute respiratory distress syndrome (ARDS), need for intensive care, and use of mechanical ventilator. RESULTS: Nineteen studies with a total of 7216 patients were included. CKD was associated with increased composite poor outcome (RR 2.63 [1.33, 5.17], P = .03; I 2 = 51%, P = .01) and its subgroup, consisting of mortality (RR 3.47 [1.36, 8.86], P = .009; I 2 = 14%, P = .32) and severe COVID-19 (RR 2.89 [0.98, 8.46], P = .05; I 2 = 57%, P = .04). RRT was associated with increased composite poor outcome (RR 18.04 [4.44, 73.25], P < .001; I 2 = 87%, P < .001), including mortality (RR 26.02 [5.01, 135.13], P < .001; I 2 = 60%, P = .06), severe COVID-19 (RR 12.95 [1.93, 86.82], P = .008; I 2 = 81%, P < .001), intensive care (IC) (RR 14.22 [1.76, 114.62], P < .01; I 2 = 0%, P < .98), and use of mechanical ventilator (RR 34.39 [4.63, 255.51], P < .0005). CONCLUSION: CKD and new-onset RRT were associated with poor outcome in patients with COVID-19.

The use of renin angiotensin system inhibitor on mortality in patients with coronavirus disease 2019 (COVID-19): A systematic review and meta-analysis.

BACKGROUND: and Aims; To investigate the association between use of angiotensin-converting enzyme inhibitor (ACEI)/angiotensin-receptor blocker (ARB) and outcomes of hypertensive COVID-19 patients, a systematic review and meta-analysis were performed. METHODS: We systematically searched PubMed, EuropePMC, ProQuest, and Cochrane Central Databases using the terms "(COVID-19 OR SARS-CoV-2) AND (angiotensin converting enzyme OR angiotensin receptor blocker)". The primary and second outcomes were mortality (non-survivor) and severe COVID-19, respectively. RESULTS: Totally, 7410 patients were included from 15 studies. Pooled analysis showed that the use of ACEI/ARB was not associated with mortality (OR 0.73 [0.38, 1.40], p = 0.34; I2: 81%) and severity (OR 1.03 [0.73, 1.45], p = 0.87; I2: 65%). Pooled adjusted OR showed no risk/benefit associated with ACEI/ARB use in terms of mortality (OR 0.83 [0.54, 1.27], p = 0.38; I2: 0%). Subgroup analysis showed that the use of ARB was associated with reduced mortality (OR 0.51 [0.29, 0.90], p = 0.02; I2: 22%) but not ACEI subgroup (OR 0.68 [0.39, 1.17], p = 0.16; I2: 0%). Meta-regression showed that the association between ACEI/ARB use and mortality in patients with COVID-19 do not varies by gender (p = 0.104). GRADE showed a very low certainty of evidence for effect of ACEI/ARB on mortality and severity. The certainty of evidence was very low for both ACEI and ARB subgroups. CONCLUSION: Administration of a renin angiotensin system (RAS) inhibitor, was not associated with increased mortality or severity of COVID-19 in patients with hypertension. Specifically, ARB and not ACEI use, was associated with lower mortality.

Is subcutaneous insulin administration adequate for the management of hyperglycemic crisis in COVID-19?

There is a desperate need to explore different insulin administration strategies, particularly in coronavirus disease 2019 (COVID-19) patients with hyperglycemic crisis. Noteworthily, diabetes mellitus (DM) and poorly controlled blood glucose increase the risk of mortality and severity of COVID-19. Intravenous (IV) insulin administration with hourly monitoring of blood glucose is the ideal approach in managing patients with hyperglycemic crisis, but it is not judicious to be applied in developing countries where shortage of personal protective equipment (PPE) is a major issue. Furthermore, increasing the probability of "already greater risks" for doctors or other healthcare workers contracting COVID-19 seems inappropriate. Thus, an alternative administration strategy and more moderate glucose monitoring to reduce the contact exposure of healthcare workers with COVID-19 patients, by ensuring appropriate blood glucose levels, needs to be performed in this critical pandemic era. Subcutaneous (SC) rapid-acting insulin analog administration could presumably be a solution to this contentious issue.
