Risk of Death in COVID-19 Patients with Comorbidity of Chronic Kidney Disease: Meta Analysis

Abstract Background and Aims Patients with chronic kidney disease (CKD) undergoing dialysis are at a particularly high risk of cardiovascular mortality and morbidity. This systematic review and meta-analysis aimed to evaluate the benefits and harms of aldosterone antagonists, both non-selective (spironolactone) and selective (eplerenone), in comparison to control (placebo or standard care) in patients with CKD requiring haemodialysis or peritoneal dialysis. Method We searched the Cochrane Kidney and Transplant Register of Studies up to 29 July 2019 using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register Search Portal and ClinicalTrials.gov. We included individual and cluster randomised controlled trials (RCTs), cross-over trials, and quasi-RCTs that compared aldosterone antagonists with placebo or standard care in patients with CKD requiring dialysis. We used a random-effects model meta-analysis to perform a quantitative synthesis of the data. We used the I2 statistic to measure heterogeneity among the trials in each analysis. We indicated summary estimates as a risk ratio (RR) for dichotomous outcomes with their 95% confidence interval (CI). We assessed the certainty of the evidence for each of the main outcomes using the GRADE (Grades of Recommendation, Assessment, Development, and Evaluation) approach. Results We included 16 trials (14 parallel RCTs and two cross-over trials) involving a total of 1,446 patients. Among included studies, 13 trials compared spironolactone to placebo or standard care and one trial compared eplerenone to a placebo. Most studies had an unclear or high risk of bias. Compared to control, aldosterone antagonists reduced the risk of all-cause death for patients with CKD requiring dialysis (9 trials, 1,119 patients: RR 0.45, 95% CI 0.30 to 0.67; moderate certainty of evidence). Aldosterone antagonist also decreased the risk of death due to cardiovascular disease (6 trials, 908 patients: RR 0.37, 95% CI 0.22 to 0.64; moderate certainty of evidence) and cardiovascular and cerebrovascular morbidity (3 trials, 328 patients: RR 0.38, 95% CI 0.18 to 0.76; moderate certainty of evidence). While aldosterone antagonists had an apparent increased risk of gynaecomastia compared with control (4 trials, 768 patients: RR 5.95, 95% CI 1.93 to 18.3; moderate certainty of evidence), the elevated risk of hyperkalaemia due to aldosterone antagonists was uncertain (9 trials, 981 patients: RR 1.41, 95% CI 0.72 to 2.78; low certainty of evidence). Conclusion Based on moderate certainty of the evidence, aldosterone antagonists could reduce the risk of all-cause and cardiovascular death and morbidity due to cardiovascular and cerebrovascular disease but increase the risk of gynaecomastia in patients with CKD requiring dialysis.

Meta Analyses

Background: Previous studies have not shown a consistent link between body mass index (BMI) and outcomes such as mortality and kidney disease progression in non-dialysis-dependent chronic kidney disease (CKD) patients. Therefore, we aimed to complete a systematic review and meta-analysis study on this subject. Methods: We searched MEDLINE, EMBASE, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Cochrane Central Register of Controlled Trials (CENTRAL), and screened 7,123 retrieved studies for inclusion. Two investigators independently selected the studies using predefined criteria and assessed each study's quality using the Newcastle-Ottawa quality assessment scale. We meta-analyzed the results based on the BMI classification system by the WHO. Results: We included 10 studies (with a total sample size of 484,906) in the systematic review and 4 studies in the meta-analyses. The study results were generally heterogeneous. However, following reanalysis of the largest reported study and our meta-analyses, we observed that in stage 3-5 CKD, being underweight was associated with a higher risk of death while being overweight or obese class I was associated with a lower risk of death; however, obesity classes II and III were not associated with risk of death. In addition, reanalysis of the largest available study showed that a higher BMI was associated with an incrementally higher risk of kidney disease progression; however, this association was attenuated in our pooled results. For earlier stages of CKD, we could not complete meta-analyses as the studies were sparse and had heterogeneous BMI classifications and/or referent BMI groups. Conclusion: Among the group of patients with stage 3-5 CKD, we found a differential association between obesity classes I-III and mortality compared to the general population, indicating an obesity paradox in the CKD population.

All Cause Mortality

Anemia is one of the major complications in predialysis patients with chronic kidney disease (CKD). A clearer cognition of the prognostic impact of hemoglobin (Hb) or hematocrit (Hct) target on the outcomes of predialysis patients with CKD is significant. This article aims to establish the suitable hemoglobin target to provide clinical guidance. MEDLINE, EmBase, the Cochrane Library and other databases were searched with both MeSH terms and keywords to gather researches that assessed all-cause mortality, stroke, treatment of renal replacement, and transfusion. The meta-analysis was accomplished via Revman 5.3 version. Totally, 13 eligible studies involving 7606 patients were included. There was a significantly lower risk of transfusion (risk ratio (RR) 0.59, 95% CI 0.52 to 0.67; p<0.00001) in the higher hemoglobin group than in the lower one. However, no significant difference was found in all-cause mortality (RR 1.10, 95% CI 0.98 to 1.23; p=0.11), stroke (RR 1.32, 95% CI 0.82 to 2.10; p=0.25) and treatment of renal replacement including hemodialysis, peritoneal dialysis and renal transplant (RR 1.08, 95% CI 0.95 to 1.22; p= 0.23) between the higher hemoglobin group and the lower one. The results favor the higher hemoglobin target. To target the higher hemoglobin when treating predialysis patients with CKD may decrease the risk of transfusion without increasing the risk of death, stoke, and treatment of renal replacement.

Inflammatory State

Coronavirus disease 19 is a global pandemic which infects over millions of people worldwide in a limited time and changes the lifestyle, clinical spectrum lies from asymptomatic infection to pneumonitis with cardiorespiratory failure and finally death. Higher mortality occurs in senior and who are suffering from co-morbidities like chronic kidney disease, (HTN) hypertension, (DM TYPE II) diabetes mellitus or (CVD) cardiovascular diseases. However, rather than normal individuals, patients with chronic kidney disease (CKD) are under higher risk for infections. The chronic systemic inflammatory state is a significant cause for morbidity and mortality in CKD patients. The objective of this review is to discuss the pathogenesis of COVID-19 in CKD, changes observed in the immune system of CKD patients, COVID-19 infections risk in CKD and therapeutic approach of COVID-19 in CKD patients. From the standpoint of frequent renal co-morbidities in covid19 patients, renal complications were explored in covid19 patients received at level 2 tertiary care Santosh Hospital, Ghaziabad, U.P. Delhi-NCR India during March to August 2020 as per the protocol of Nephrology Society of India. Relevant clinical trials were reviewed in support. Meta-analysis and clinical trials are covered in this review study. Duplicate studies are not taken into account. The outcome of the studies shows that CKD patients are more prone to COVID-19. CKD patients are more likely infected with COVID-19 virus. Whereas in intensive care, CKD occurs more frequent than DM type II and CVD. So,COVID-19 pathogenesis in CKD patients, risk of COVID-19, immunologic changes and therapy COVID-19 in CKD can add support in the effective management of COVID-19.
