Safety and efficacy of colchicine in COVID-19 patients: A systematic review and meta-analysis of randomized control trials

Background: Colchicine has been used an effective anti-inflammatory drug to treat gout diseases. Owing to its pharmacodynamic of inhibiting interleukins, it has been repurposed to target the cytokine storm post-SARS-CoV-2 invasion. The goal of this meta-analysis was to evaluate the safety profile of colchicine in COVID-19 patients using the gold-standard randomised-control trials. Methods: Electronic databases (Pubmed, Google Scholar, and Cochrane) were systematically searched until June 2021 and RCTs were extracted. Outcomes of interest included all-cause mortality, COVID-19 severity, mechanical ventilation, C-reactive protein and D-dimer levels. Using a random-effects model, dichotomous outcomes were pooled using odds ratios (OR) through the generic inverse variance formula while weighted mean differences were calculated using the Wan\u27s method. P-values \u3c 0.05 were considered statistically significant for all outcomes. Results: A total population of 16,048 from five RCTs were included in the analysis. Of this, 7957 were randomized to colchicine, and 8091 received standard care, with an average age of 60.67 years. Colchicine was observed to significantly reduce COVID-19 severity (OR: 0.41, 95% CI [0.22, 0.76]; p = 0.005), and CRP levels (WMD: -19.99, 95% CI [-32.09, -7.89]; p = 0.001). However, there was no significant difference in D-dimer levels (WMD: 0.31, 95% CI [-0.61, 1.23]; p = 0.51), mechanical ventilation (OR: 0.42, 95% CI [0.17, 1.03]; p = 0.06; I2 = 74%) and all-cause mortality (OR: 0.98, 95% CI [0.83, 1.16]; p = 0.84) among patients receiving colchicine or standard care. Conclusion: Colchicine treatment decreased CRP levels and COVID-19 severity, with dimer levels, all-cause mortality and mechanical ventilation remaining seemingly unaffected. Thus, clinical trials need to be carried out that allow effective evaluation of colchicine in COVID-19 patients

Comparative analysis of neutrophil to lymphocyte ratio and derived neutrophil to lymphocyte ratio with respect to outcomes of in-hospital coronavirus disease 2019 patients: A retrospective study

Introduction and objectivesIn patients with coronavirus disease 2019 (COVID-19), several abnormal hematological biomarkers have been reported. The current study aimed to find out the association of neutrophil to lymphocyte ratio (NLR) and derived NLR (dNLR) with COVID-19. The objective was to compare the accuracy of both of these markers in predicting the severity of the disease.Materials and methodsThe study was conducted in a single-center having patients with COVID-19 with a considerable hospital stay. NLR is easily calculated by dividing the absolute neutrophil count (ANC) with the absolute lymphocyte count (ALC) {ANC/ALC}, while dNLR is calculated by ANC divided by total leukocyte count minus ANC {ANC/(WBC-ANC)}. Medians and interquartile ranges (IQR) were represented by box plots. Multivariable logistic regression was performed obtaining an odds ratio (OR), 95% CI, and further adjusted to discover the independent predictors and risk factors associated with elevated NLR and dNLR.ResultsA total of 1,000 patients with COVID-19 were included. The baseline NLR and dNLR were 5.00 (2.91–10.46) and 4.00 (2.33–6.14), respectively. A cut-off value of 4.23 for NLR and 2.63 for dNLR were set by receiver operating characteristic (ROC) analysis. Significant associations of NLR were obtained by binary logistic regression for dependent outcome variables as ICU stay (p < 0.001), death (p < 0.001), and invasive ventilation (p < 0.001) while that of dNLR with ICU stay (p = 0.002), death (p < 0.001), and invasive ventilation (p = 0.002) on multivariate analysis when adjusted for age, gender, and a wave of pandemics. Moreover, the indices were found correlating with other inflammatory markers such as C-reactive protein (CRP), D-dimer, and procalcitonin (PCT).ConclusionBoth markers are equally reliable and sensitive for predicting in-hospital outcomes of patients with COVID-19. Early detection and predictive analysis of these markers can allow physicians to risk assessment and prompt management of these patients

The Menace of Candida auris Epidemic Amidst the COVID-19 Pandemic: A Systematic Review

Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), the causative agent for the Coronavirus Disease 2019 (COVID-19) pandemic, has sparked a medical emergency worldwide. With the rise in COVID-19 infections and an eventual increase in hospitalized critically ill patients, a trend of bacterial, fungal, and viral superinfection has been noted. One important agent of co-infection identified is Candida auris. Due to its multidrug-resistant nature and easy transmissibility, C. auris is difficult to manage in COVID-positive patients. Patients with comorbidities, immunosuppressive states, intubated and on ventilators are more likely to contract the fungal infection. Therefore, it is essential to the first screen, diagnose, and isolate patients with C. auris infection and manage and treat them while preventing the spread of the disease. Failure to recognize and prevent its spread may lead to an eventual epidemic or even a pandemic during the current COVID-pandemic, which the exhausted healthcare system can most definitely not handle. This systematic review investigates the prevalence of C. auris, its pathophysiology, diagnosis, prevention, and treatment during the COVID-19 pandemic

Efficacy and Safety of Concomitant Tricuspid Repair in Patients Undergoing Mitral Valve Surgery: a Systematic Review and Meta-Analysis.

Tricuspid valve repair (TVR) is recommended for patients with moderate primary tricuspid regurgitation (TR), those with moderate TR, and a history of heart failure without annular dilation, while being essential for patients with severe secondary TR undergoing MVS. The meta-analysis aimed to evaluate the efficacy and safety of tricuspid valve repair in patients undergoing MVS. We systematically searched PubMed, Embase, and Google Scholar through January 2022, and studies comparing patients with TVR and those without TVR were selected. The primary outcomes were 30-day, and all-cause mortality. In this meta-analysis, 20 studies were included with a patient population of 72,422. No significant differences were observed between patients undergoing TVR with MVS, in comparison to MVS group only for the primary outcomes i.e., 30-day mortality (RR: 1.14, 95% CI [0.69, 1.87], and all-cause mortality (RR: 1.16, 95% CI [0.86, 1.57]. From the secondary outcomes, pacemaker insertion (RR: 2.62, 95% CI [2.24, 3.06]), new-onset TR or progression (RR: 0.32, 95% CI [0.16, 0.66]), stroke (RR: 1.22, 95% CI [1.05, 1.42]), cross-clamp time (WMD: 17.67, 95% CI [13.96, 21.37]), surgery time (WMD: 43.59, 95% CI [37.07, 50.10]), ICU time (WMD: 19.50, 95% CI [9.31, 29.67]), and ventilation time (WMD: 6.62, 95% CI [0.69, 12.55]) were significant. However, major bleeding events, atrial fibrillation, renal failure, heart failure hospitalization, postoperative MI, wound infection, early or prolonged morbidity, cardiopulmonary bypass time, and duration of hospital stay were non-significant. Our meta-analysis has furthered the discussion for weighing the risks and benefits of pursuing TVR during MVS

Self-medication practices in medical students during the COVID-19 pandemic: A cross-sectional analysis

Background and objectives: During the pandemic, the growing influence of social media, accessibility of over-the-counter medications, and fear of contracting the virus may have led to self-medication practices among the general public. Medical students are prone to such practices due to relevant background knowledge, and access to drugs. This study was carried out to determine and analyze the prevalence of self-medication practices among medical students in Pakistan. Materials and methods: This descriptive, cross-sectional study was conducted online in which the participants were asked about the general demographics, their self-medication practices and the reasons to use. All participants were currently enrolled in a medical college pursuing medical or pharmacy degree. Non-probability sampling technique was used to recruit participants. Results: A total of 489 respondents were included in the final analysis. The response rate was 61%. Majority of the respondents were females and 18-20 years of age. Self-medication was quite prevalent in our study population with 406 out of 489 individuals (83.0%) were using any of the drugs since the start of pandemic. The most commonly utilized medications were Paracetamol (65.2%) and multivitamins (56.0%). The reasons reported for usage of these medications included cold/flu, or preventive measures for COVID-19. The common symptoms reported for self-medication included fever (67.9%), muscle pain (54.0%), fatigue (51.7%), sore throat (46.6%), and cough (44.4%). Paracetamol was the most commonly used drug for all symptoms. Female gender, being in 3rd year of medical studies, and individuals with good self-reported health were found more frequent users of self-medication practices. Conclusion: Our study revealed common self-medication practices among medical and pharmacy students. It is a significant health issue especially during the pandemic times, with high consumption reported as a prevention or treating symptoms of COVID-19

Current practices and considerations for transcatheter mitral valve implantation based on risk stratification among patients with mitral valve regurgitation

Mitral Regurgitation (MR) is the most common form of severe valvular disease occurring in developed countries, being caused either primarily on its own or secondary to cardiac disease. Surgical intervention is required for the correction of MR, which could include the replacement or repair of the affected valve. Transcatheter Mitral Valve Replacement (TMVR) in selected patients is of increasing importance, especially after the success of Transcatheter Aortic Valve Replacement. TMVR can be divided into 3 types, that is, valve-in-valve for severe mitral valve disease, valve-in-ring for failed surgical repairs, and valve-in-mitral annular calcifications for mitral valvular disease with severe mitral annular calcifications and poor surgical criteria. The FDA approved Mitral valve-in-valve for patients with a high surgical risk in 2017, while valve-in-ring and valve-in-mitral annular calcifications are still currently under consideration. The SAPIEN M3 valve is relatively new with a trans-septal system, with a success rate of 86%, and no mortality in a 30-day outcome. The Cardiovalve is a bovine pericardium device that has a dual nitinol frame with a custom surgical design to facilitate TMVR. The AHEAD trial will evaluate whether the device is safe to use in a clinical setting and how effective it is for reducing MR in these patients. The trial consists of 30 patients in which the first 5 patients showed 100% technical success and a reduction of MR. This evolution of modern medicine has assisted in many different countries, including Pakistan where there is a higher prevalence of MR and hence, a greater need to apply TMVR in clinical practice

Mitral Valve Replacement: A Review of Current Practices and Considerations in Low and High-Risk Patients.

Mitral Regurgitation (MR) is the most common form of severe valvular disease occurring in developed countries, being caused either primarily on its own or secondary to cardiac disease. Surgical intervention is required for the correction of MR, which could include the replacement or repair of the affected valve. Transcatheter Mitral Valve Replacement (TMVR) in selected patients is of increasing importance, especially after the success of Transcatheter Aortic Valve Replacement (TAVR). TMVR can be divided into three types i.e., valve-in-valve (ViV) for severe mitral valve disease, valve-in-ring (ViR) for failed surgical repairs, and valve-in-mitral annular calcifications (ViMAC) for mitral valvular disease with severe mitral annular calcifications and poor surgical criteria. The FDA approved Mitral ViV for patients with a high surgical risk in 2017, while ViR and ViMAC are still currently under consideration. The SAPIEN M3 valve is relatively new with a trans-septal system, with a success rate of 86%, and no mortality in a 30-day outcome.

COVID-19 Associated Mucormycosis: A Systematic Review from Diagnostic Challenges to Management

The coronavirus disease 2019 (COVID-19) outbreak has caused significant destruction, claiming over three million lives worldwide. Post SARS-COV-2 invasion, immunosuppression with hyperglycemia and elevated ferritin levels along with steroidal treatment creates a perfect storm for opportunistic infections. There is increasing evidence of mucormycosis co-infection in COVID-19 patients, during or post-treatment. A worse prognosis, a late diagnosis, and limited guidelines of screening and management of COVID-19 associated mucormycosis have made healthcare professionals fear an epidemic alongside a pandemic. This review geographically reports cases of COVID-19 associated mucormycosis (CAM), evaluates characteristics, clinical manifestations, and outcomes of mucormycosis in COVID-19 active or recovered patients. It further describes preventive strategies and recommendations for optimal management therapy that can be adopted worldwide to curtail an impending threat to the healthcare system

Early transcatheter or surgical aortic valve replacement versus conservative management in asymptomatic patients with severe aortic stenosis: A systematic review and meta-analysis

The merits of conservative management versus early intervention in patients with asymptomatic severe aortic stenosis remain unknown. Digital databases (MEDLINE, Google Scholar, and Embase) were searched for all relevant studies from inception through September 2022. Studies comparing conservative management with early intervention were compared using a random-effects model to calculate risk ratios (RRs) with 95% confidence interval (CI). A total of 11 studies comprising 5,030 patients (1,874 patients were in the early intervention i.e., surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR) group, and 3,156 in the conservative group) were included in the analysis. The average follow-up time was 4.49 years. Early intervention was associated with a significantly reduced risk of heart failure hospitalization (RR 0.27, 95% CI 0.11- 0.67; P = 0.004), cardiac (RR 0.38, 95% CI 0.26 - 0.56; P \u3c 0.00001), non-cardiac (RR 0.40, 95% CI 0.31-0.50; P \u3c 0.00001), and all-cause mortality (RR 0.35, 95% CI 0.27 - 0.44; P \u3c 0.00001) compared with conservative management. There was no significant difference in the 30-day mortality (RR 1.30, 95% CI 0.22 - 7.66; P = 0.77), 90-day mortality (RR 0.49, 95% CI 0.12 - 2.02; P = 0.32) or myocardial infarction (RR 0.57, 95% CI 0.32 - 1.02; P = 0.06) between the two groups. This meta-analysis shows statistically significant reductions in the risk for all-cause mortality, cardiac specific mortality, non-cardiac mortality, sudden cardiac death, and heart failure hospitalizations in patients with asymptomatic aortic stenosis who underwent early intervention as opposed to conservative management

Efficacy and safety of finerenone in chronic kidney disease and type 2 diabetes patients: a systematic review and meta-analysis.

BACKGROUND AND OBJECTIVES: The incidence of morbidity and mortality in patients with type 2 diabetes mellitus is substantially correlated with cardiovascular disease and chronic kidney disease. The current guidelines recommend the use of renin-angiotensin system blockers, but recent studies probed into the effects of finerenone to mitigate the risk of cardiorenal events. This meta-analysis was performed to demonstrate the effects of finerenone on cardiorenal events, comprising cardiovascular mortality, heart failure, change in estimated glomerular filtration rate, and serum potassium levels. METHODS: After screening with our eligibility criteria, 350 articles were identified with an initial literature search on multiple databases, including PubMed, Science Direct, and Cochrane Central. Seven randomized controlled trials with a total of 15 462 patients ( RESULTS: Patients receiving finerenone were at a reduced risk for cardiovascular mortality [HR: 0.84 (0.74, 0.95)], heart failure [OR: 0.79 (0.68, 0.92)], decrease in estimated glomerular filtration rate by 40% [OR: 0.82 (0.74, 0.91)] and by 57% [OR: 0.70 (0.59, 0.82)]; and a higher incidence of moderate hyperkalemia [OR: 2.25 (1.78, 2.84)]. CONCLUSION: Finerenone, owing to its better mineralocorticoid affinity, and a much lower risk of adverse effects, promises to be a much better alternative than other renin-angiotensin system blockers available for the treatment of chronic kidney disease patients with type 2 diabetes. Further trials should be conducted to provide more definitive evidence to assess the safety and efficacy of finerenone compared to spironolactone and eplerenone
