A COVID-19 patient often presents with multiple comorbidities and is associated with adverse outcomes. A comprehensive assessment of the prevalence of comorbidities in patients with COVID-19 is essential. This study aimed to assess the prevalence of comorbidities, severity and mortality with regard to geographic region, age, gender and smoking status in patients with COVID-19. A systematic review and multistage meta-analyses were reported using PRISMA guidelines. PubMed/MEDLINE, SCOPUS, Google Scholar and EMBASE were searched from January 2020 to October 2022. Cross-sectional studies, cohort studies, case series studies, and case–control studies on comorbidities reporting among the COVID-19 populations that were published in English were included. The pooled prevalence of various medical conditions in COVID-19 patients was calculated based on regional population size weights. Stratified analyses were performed to understand the variations in the medical conditions based on age, gender, and geographic region. A total of 190 studies comprising 105 million COVID-19 patients were included. Statistical analyses were performed using STATA software, version 16 MP (StataCorp, College Station, TX). Meta-analysis of proportion was performed to obtain pooled values of the prevalence of medical comorbidities: hypertension (39%, 95% CI 36–42, n = 170 studies), obesity (27%, 95% CI 25–30%, n = 169 studies), diabetes (27%, 95% CI 25–30%, n = 175), and asthma (8%, 95% CI 7–9%, n = 112). Moreover, the prevalence of hospitalization was 35% (95% CI 29–41%, n = 61), intensive care admissions 17% (95% CI 14–21, n = 106), and mortality 18% (95% CI 16–21%, n = 145). The prevalence of hypertension was highest in Europe at 44% (95% CI 39–47%, n = 68), obesity and diabetes at 30% (95% CI, 26–34, n = 79) and 27% (95%CI, 24–30, n = 80) in North America, and asthma in Europe at 9% (95% CI 8–11, n = 41). Obesity was high among the ≥ 50 years (30%, n = 112) age group, diabetes among Men (26%, n = 124) and observational studies reported higher mortality than case–control studies (19% vs. 14%). Random effects meta-regression found a significant association between age and diabetes (p < 0.001), hypertension (p < 0.001), asthma (p < 0.05), ICU admission (p < 0.05) and mortality (p < 0.001). Overall, a higher global prevalence of hypertension (39%) and a lower prevalence of asthma (8%), and 18% of mortality were found in patients with COVID-19. Hence, geographical regions with respective chronic medical comorbidities should accelerate regular booster dose vaccination, preferably to those patients with chronic comorbidities, to prevent and lower the severity and mortality of COVID-19 disease with novel SARS-CoV-2 variants of concern (VOC).
Proton pump inhibitors are very commonly prescribed drugs for gastrointestinal disorders. It is estimated that worldwide a total of 537 million adult populations are affected by diabetes mellitus. The present systematic review was planned to explore an association between PPIs use and the risk of DM occurrence which is unclear yet. We have performed a comprehensive literature search in popular electronic databases such as Pub Med, Embase, Scopus, Cochrane Library and ClinicalTrials.gov using a comprehensive search strategy from inception to December 2022. Quality analysis was assessed using the Newcastle-Ottawa scale system. All Statistical analyses were performed using the “Review Manager 5.4” version. The P value < .05 was set as statistically highly significant. This systematic review identified 12 studies (8: observational; 1: RCT & 3: case-control; n = 11, 64816) with a total of 1, 25,504 cases of diabetes incidence, and the median age ranged from > 18-74.9 years. The pooled RR findings have shown that exposure to PPIs is significantly associated with an increased risk of DM occurrence (RR, 2.44; 95% CI, 1.31–4.54) with high heterogeneity (I2 = 99%, P < 0.00001). A significant relationship between the chronic use of PPIs and the development of diabetes mellitus was found. Hypergastrenemia, gut dysbiosis, hypomagnesaemia, decrease pancreatic secretions, PXR activation, decrease in the levels of insulin-like growth factor-1 and low potency are some of the mechanisms proposed to explain an association of diabetes incidence with chronic PPI use. Furthermore, RCTs on PPIs associated risk of diabetes incidence are suggested
Background: Various cardiac complications such as cardiomyopathy and sudden cardiac death have been associated with Coronavirus disease 2019 (COVID-19) pandemic. We present a case of late pericardial effusion after resolution of takotsubo cardiomyopathy in COVID-19. Case Report: A 46-year-old male presented with acute hypoxic respiratory failure secondary to COVID-19 pneumonia. His left ventricular ejection fraction (LVEF) was 55% at admission. Over the next two days, his condition worsened requiring mechanical ventilation and inotropic support. A repeat echocardiogram revealed severe biventricular systolic dysfunction with basal hypercontractility and a drop in LVEF to 25%. Cardiac catheterization showed clean coronaries, elevated filling pressures, and reduced cardiac index (CI:1.44L/min/m 2 ); hence cardiogenic shock secondary to viral myocarditis/takotsubo cardiomyopathy was suspected and an impella was placed. His condition improved with high-dose steroids, diuretics, and heart failure medication. He was subsequently weaned off circulatory and inotropic support and LVEF improved to 60% in four days, hence a provisional diagnosis of takotsubo cardiomyopathy was made. However, three days post-Impella removal he became tachycardic and hypotensive and a repeat echocardiogram showed moderate pericardial effusion with purulent material and Right Ventricle (RV) free wall diastolic collapse(image). He underwent emergent pericardiocentesis draining 800 ml of purulent fluid with pericardial drain placement. Pericardial fluid cultures returned negative. Thereafter, his condition significantly improved and he was discharged on hospital day 15. Conclusion: Symptomatic pericardial effusion can occur late in the clinical course even after other cardio-pulmonary symptoms have improved. This case highlights the importance of clinician awareness of the various cardiac complications in COVID-19 and their timely diagnosis and management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
