The mortality and severity in COVID-19 is increased in patients with comorbidities. The aim of this study was to evaluate the severity and mortality in COVID-19 patients with underlying kidney and liver diseases. We retrieved data on the clinical features and primary composite end point of COVID-19 patients from Medline and Embase which had been released from inception by the April 16, 2020. The data on two comorbidities, liver diseases and chronic kidney disease, were pooled and statistically analysed to explain the associated severity and mortality rate. One hundred and forty-two abstracts were screened, and 41 full articles were then read. In total, 22 studies including 5595 COVID-19 patients were included in this study with case fatality rate of 16%. The prevalence of liver diseases and chronic kidney disease (CKD) were 3% (95% CI; 2–3%) and 1% (95% CI; 1–2%), respectively. In patients with COVID-19 and underlying liver diseases, 57.33% (43/75) of cases were severe, with 17.65% mortality, while in CKD patients, 83.93% (47/56) of cases were severe and 53.33% (8/15) mortality was reported. This study found an increased risk of severity and mortality in COVID-19 patients with liver diseases or CKD. This will lead to better clinical management and inform the process of implementing more stringent preventative measures for this group of patients.

Background: The mortality and severity in COVID-19 is increased in patients with comorbidities. The aim of this study was to evaluate the unknown risk of severity and mortality in COVID-19 patients with underlying kidney and liver diseases. Method: We retrieved data on the clinical features and primary composite end point of COVID-19 patients released from inception till 16th of April 2020 from Medline and Embase. The data on two comorbidities, liver diseases and chronic kidney disease, present in COVID-19 were pooled and statistically analysed to explain the associated severity and mortality rate. Results: 142 abstracts were screened, and 41 full articles were then read. In total, 22 studies including 5595 COVID-19 patients were included in this study with case fatality rate of 16%. The prevalence of liver diseases and CKD were 3% (95%CI; 2%-3%) and 1% (95%CI; 1%-2%) respectively. In patients with COVID-19 and underlying liver diseases, 57.33% (43/75) cases were severe with 17.65% mortality. While in CKD patients with COVID-19, 83.93% (47/56) severity and 53.33% (8/15) mortality were reported. Conclusion: This study found an increased risk of severity and mortality in COVID-19 patients with liver diseases and CKD. This will allow for better clinical management and inform more stringent preventative measures for this group of patients.

Chronic kidney diseases and cardiovascular diseases have several common risk factors like hypertension and diabetes. In chronic renal disease stroke risk is several times higher than in the average population. The combination of classical risk factors and those characteristic of chronic kidney disease might explain this increased risk. Among acute cerebrovascular diseases intracerebral hemorrhages are more frequent than in those with normal kidney function. The outcome of stroke is worse in chronic kidney disease. The treatment of stroke (thrombolysis, antiplatelet and anticoagulant treatment, statins, etc.) is an area of clinical research in this patient group. There are no reliable data on the application of thrombolysis in acute stroke in patients with chronic renal disease. Aspirin might be administered. Carefulness, individual considerations and lower doses might be appropriate when using other treatments. The condition of the kidney as well as other associated diseases should be considered during administration of antihypertensive and lipid lowering medications.

AbstractIncidence of hip fractures has remained unchanged during the pandemic with overlapping vulnerabilities observed in patients with hip fractures and those infected with COVID-19. We aimed to investigate the independent impact of COVID-19 infection on the mortality of these patients. Healthcare databases were systematically searched over 2-weeks from 1st–14th November 2020 to identify eligible studies assessing the impact of COVID-19 on hip fracture patients. Meta-analysis of proportion was performed to obtain pooled values of prevalence, incidence and case fatality rate of hip fracture patients with COVID-19 infection. 30-day mortality, excess mortality and all-cause mortality were analysed using a mixed-effects model. 22 studies reporting 4015 patients were identified out of which 2651 (66%) were assessed during the pandemic. An excess mortality of 10% was seen for hip fractures treated during the pandemic (OR 2.00, p = 0.007), in comparison to the pre-pandemic controls (5%). Estimated mortality of COVID-19 positive hip fracture patients was four-fold (RR 4.59, p < 0.0001) and 30-day mortality was 38.0% (HR 4.73, p < 0.0001). The case fatality rate for COVID-19 positive patients was 34.74%. Between-study heterogeneity for the pooled analysis was minimal (I2 = 0.00) whereas, random effects metaregression identified subgroup heterogeneity for male gender (p < 0.001), diabetes (p = 0.002), dementia (p = 0.001) and extracapsular fractures (p = 0.01) increased risk of mortality in COVID-19 positive patients.

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.

Background: Recent findings suggest that mild chronic kidney disease (CKD) might be associated with increased risk of venous thromboembolism (VTE). However, results were partially inconsistent, which may be due to lack of power. We therefore performed a meta-analysis to investigate the association between mild CKD and VTE incidence. Methods: A literature search was performed to retrieve community-based cohorts with information on the association of estimated glomerular filtration rate (eGFR) and albuminuria with VTE. Five cohorts were identified that were pooled on individual level. To obtain pooled hazard ratios (HRs) for VTE, linear spline models were fitted using Cox regression with shared-frailty. Models were adjusted for age, sex, hypertension, total cholesterol, smoking, diabetes, history of cardiovascular disease and body-mass index. Random-effect meta-analysis was used to obtain adjusted pooled HRs of VTE with CKD versus no CKD. Results: The analysis included 95,154 participants with 1,178 VTE cases and 599,453 person-years of follow-up. Risk of VTE increased continuously with lower eGFR and higher ACR (Figure). Compared with eGFR 100 mL/min/1.73m², pooled adjusted HRs for VTE were 1.3 (1.0–1.7) for eGFR 60, 1.8 (1.3–2.6) for 45 and 1.9 (1.2–2.9) for 30 mL/min/1.73m². Compared with albumin-creatinine ratio (ACR) 5 mg/g, pooled adjusted HRs for VTE were 1.3 (1.04–1.7) for ACR 30, 1.6 (1.1–2.4) for 300 and 1.9 (1.2–3.1) for 1000 mg/g. There was no evidence for interaction between eGFR and ACR (P=0.22). The pooled adjusted HR for CKD (eGFR <60 ml/min/1.73m² or albuminuria ≥30 mg/g) vs. no CKD was 1.5 (95%CI, 1.2–2.1). Results were similar for idiopathic and provoked VTE. Conclusion: Both reduced eGFR and elevated albuminuria are novel independent predictors of VTE in the general population.

Background Although the relationship between a history of kidney stones and chronic kidney disease (CKD) has been explored in many studies, it is still far from being well understood. Thus, we conducted a meta-analysis of studies comparing rates of CKD in patients with a history of kidney stones. Methods PubMed, EMBASE, and the reference lists of relevant articles were searched to identify observational studies related to the topic. A random-effects model was used to combine the study-specific risk estimates. We explored the potential heterogeneity by subgroup analyses and meta-regression analyses. Results Seven studies were included in this meta-analysis. Pooled results suggested that a history of kidney stones was associated with an increased adjusted risk estimate for CKD [risk ratio (RR), 1.47 95% confidence interval (CI) [1.23–1.76])], with significant heterogeneity among these studies (I2 = 93.6%, P < 0.001). The observed positive association was observed in most of the subgroup analyses, whereas the association was not significant among studies from Asian countries, the mean age ≥50 years and male patients. Conclusion A history of kidney stones is associated with increased risk of CKD. Future investigations are encouraged to reveal the underlying mechanisms in the connection between kidney stones and CKD, which may point the way to more effective preventive and therapeutic measures.

Abstract Background Cardiovascular disease is an important driver of the increased mortality associated with chronic kidney disease (CKD). Higher left ventricular mass (LVM) predicts increased risk of adverse cardiovascular outcomes and total mortality, but previous reviews have shown no clear association between intervention-induced LVM change and all-cause or cardiovascular mortality in CKD. Methods The primary objective of this meta-analysis was to investigate whether treatment-induced reductions in LVM over periods ≥ 12 months were associated with all-cause mortality in patients with CKD. Cardiovascular mortality was investigated as a secondary outcome. Measures of association in the form of relative risks (RRs) with associated variability and precision (95% confidence intervals [CIs]) were extracted directly from each study, when reported, or were calculated based on the published data, if possible, and pooled RR estimates were determined. Results The meta-analysis included 38 trials with duration ≥ 12 months: 6 of erythropoietin stimulating agents treating to higher vs. lower hemoglobin targets, 10 of renin-angiotensin-aldosterone system inhibitors vs. placebo or another blood pressure lowering agent, 14 of modified hemodialysis regimens, and 8 of other types of interventions. All-cause mortality was reported in 116/2385 (4.86%) subjects in intervention groups and 161/2404 (6.70%) subjects in control groups. The pooled RR estimate of the 24 trials ≥ 12 months with ≥ 1 event in ≥ 1 group was 0.72 (95% CI 0.57 to 0.91, p = 0.005), with little heterogeneity across studies. Directionalities of the associations in intervention subgroups were the same. Sensitivity analyses of ≥ 6 months (31 trials), ≥ 9 months (26 trials), and > 12 months (9 trials), and including studies with no events in either group, demonstrated similar risk reductions to the primary analysis. The point estimate for cardiovascular mortality was similar to all-cause mortality, but not statistically significant: RR 0.66, 95% CI 0.38 to 1.15. Conclusions These results suggest that LVM regression may be a useful surrogate marker for benefits of interventions intended to reduce mortality risk in patients with CKD.

Abstract Background Previous studies have indicated coronavirus disease 2019 (COVID-19) patients with cancer have a high fatality rate. Methods We conducted a systematic review of studies that reported fatalities in COVID-19 patients with cancer. A comprehensive meta-analysis that assessed the overall case fatality rate and associated risk factors was performed. Using individual patient data, univariate and multivariable logistic regression analyses were used to estimate odds ratios (OR) for each variable with outcomes. Results We included 15 studies with 3019 patients, of which 1628 were men; 41.0% were from the United Kingdom and Europe, followed by the United States and Canada (35.7%), and Asia (China, 23.3%). The overall case fatality rate of COVID-19 patients with cancer measured 22.4% (95% confidence interval [CI] = 17.3% to 28.0%). Univariate analysis revealed age (OR = 3.57, 95% CI = 1.80 to 7.06), male sex (OR = 2.10, 95% CI = 1.07 to 4.13), and comorbidity (OR = 2.00, 95% CI = 1.04 to 3.85) were associated with increased risk of severe events (defined as the individuals being admitted to the intensive care unit, or requiring invasive ventilation, or death). In multivariable analysis, only age greater than 65 years (OR = 3.16, 95% CI = 1.45 to 6.88) and being male (OR = 2.29, 95% CI = 1.07 to 4.87) were associated with increased risk of severe events. Conclusions Our analysis demonstrated that COVID-19 patients with cancer have a higher fatality rate compared with that of COVID-19 patients without cancer. Age and sex appear to be risk factors associated with a poorer prognosis.

Abstract Background Blood pressure (BP) control is critical in delaying the progression of chronic kidney disease (CKD), which otherwise results in an increased risk of cardiovascular morbidity and mortality. Angiotensin II receptor blockers (ARBs) or angiotensin-converting enzyme inhibitors, are recommended by several guidelines as first-line treatment for patients with hypertension and CKD. Purpose We reviewed and analysed the effect of ARB treatment on BP and renal outcomes (estimated glomerular filtration rate (eGFR), serum creatinine (SCr), creatinine clearance (CrCl) or proteinuria) in patients with hypertension and CKD with or without diabetes, including large clinical trials such as RENAAL and IDNT. Methods MEDLINE, EMBASE, and BIOSIS databases were searched for literature from the earliest available date to July 2017. Randomised (parallel-group) controlled trials of ≥8 weeks assessed the impact of ARBs on systolic/diastolic BP (SBP/DBP), eGFR, SCr, CrCl or proteinuria were included in the analysis. Meta-analysis (post- versus pre-treatment) and meta-regression were conducted in R-statistical software (v3.4.1) using meta- and metafor-packages. Mean difference (MD, generic inverse variance) with 95% confidence intervals (CIs) was used to pool data for an outcome in a single forest plot. The risk of bias (quality) of included studies was assessed by the six items of the Cochrane instrument. Results Of the 165 articles assessed for eligibility, 24 studies were included in the analysis (19 evaluated ARBs as monotherapy, 4 evaluated ARBs in combination with other antihypertensives and 1 evaluated ARBs both as mono- and combination therapy). Treatment with ARBs as monotherapy for ≥8 weeks to <1 year significantly reduced mean office SBP (MD, −12.60 mmHg; 95% CI, −18.53 to −6.67)/DBP (−6.52 mmHg; −11.27 to −1.77) (p<0.01). BP reduction was also significant (p<0.01) with ARB monotherapy for ≥1 year SBP (−14.84 mmHg; −17.82 to −11.85)/DBP (−10.27 mmHg; −12.26 to −8.27). ARBs also significantly reduced SBP/DBP when combined with other antihypertensive treatments for ≥8 weeks to <1 year as well as for ≥1 year (Figure). Moreover, ARBs induced significant reductions (p<0.01) in proteinuria (≥8 weeks to <1 year [MD, −0.6 g/L; 95% CI, −0.93 to −0.26; ≥1 year [−0.9 g/L; −1.22 to −0.59]), but no significant changes in eGFR, CrCl or SCr levels. The beneficial effect of ARBs was maintained overtime with no significant additional impact on SBP change (estimate: 0.025; 95% CI, –0.14 to 0.19) or eGFR (estimate: 0.068; 95% CI, −0.14 to 0.28; p=0.53). The overall risk of bias was judged to be low. Effect of ARBs on blood pressure changes Conclusion Treatment with ARBs effectively and sustainably lowered BP and proteinuria with no significant change in eGFR in patients with hypertension and CKD with or without diabetes.
