The Impact of Chronic Kidney Disease on Outcomes of Patients with COVID-19 Admitted to the Intensive Care Unit

Context: Coronavirus disease 2019 (COVID-19) disproportionately impacts patients with chronic kidney disease (CKD), especially those with kidney failure requiring replacement therapy (KFRT). Patients with KFRT have increased risk of developing COVID-19, and though initial reports suggested that mortality of these patients in the intensive care unit (ICU) setting is prohibitively high, those studies suffered from significant limitations. Subject of Review: The Study of the Treatment and Outcomes in Critically Ill Patients With COVID-19 (STOP-COVID) is a multicenter cohort study that enrolled adults with COVID-19 admitted to ICUs in 68 medical centers across the USA. STOP-COVID investigators compared characteristics at the time of ICU admission and clinical outcomes in 143 patients with KFRT, 521 with nondialysis-dependent CKD (ND-CKD), and 3,600 patients without CKD. Patients with KFRT were less likely to have typical COVID-19 symptoms but more likely to have altered mental status at the time of ICU admission and were less likely to require mechanical ventilation during hospitalization than those without kidney disease. Approximately, 50% of patients with KFRT and ND-CKD died within 28 days of ICU admission, and in fully adjusted models, patients with KFRT and ND-CKD had 1.41- and 1.25-fold higher risk of 28-day mortality than those without CKD. Patients with KFRT and ND-CKD were also less likely to receive emerging therapies for COVID-19 than those without CKD. Second Opinion: This study provides important new data demonstrating differences in clinical presentation in patients with KFRT and ND-CKD with COVID-19. Alhough patients with severe CKD had higher mortality than those without CKD, approximately half survived after 28 days, demonstrating that patients with COVID-19 and severe CKD can benefit from ICU care. The markedly lower use of emerging COVID-19 treatments in patients with severe CKD highlights the need to include these patients in clinical trials of new COVID-19 therapies and for clinicians to ensure equal access to care in patients with severe CKD and COVID-19.

Cardiovascular Mortality Risk

Chronic kidney disease (CKD) is a significant health challenge associated with high cardiovascular mortality risk. Historically, cardiovascular mortality risk has been found to higher in men than women in the general population. However, recent research has highlighted that this risk may be similar or even higher in women than men in the CKD population. To address the inconclusive and inconsistent evidence regarding this relationship between sex and cardiovascular mortality within CKD patients, a systematic review and meta-analysis of articles published between January 2004 and October 2020 using PubMed/Medline, EMBASE, Scopus and Cochrane databases was performed. Forty-eight studies were included that reported cardiovascular mortality among adult men relative to women with 95% confidence intervals (CI) or provided sufficient data to calculate risk estimates (RE). Random effects meta-analysis of reported and calculated estimates revealed that male sex was associated with elevated cardiovascular mortality in CKD patients (RE 1.13, CI 1.03–1.25). Subsequent subgroup analyses indicated higher risk in men in studies based in the USA and in men receiving haemodialysis or with non-dialysis-dependent CKD. Though men showed overall higher cardiovascular mortality risk than women, the increased risk was marginal, and appropriate risk awareness is necessary for both sexes with CKD. Further research is needed to understand the impact of treatment modality and geographical distribution on sex differences in cardiovascular mortality in CKD.

Background: Hyponatremia (serum Na+ < 135 mmol/L) is the most common electrolyte abnormality detected in clinical practice and an important cause of mortality and morbidity in hospital settings. Hyponatremia in patients with pneumonia is usually mild but is associated with increased risk of intensive care unit (ICU) admission, prolonged hospital stays, and increased mortality rates. The purpose of this study is to understand the impact of varying degrees of hyponatremia and various other inflammatory markers on the severity and outcome of coronavirus disease-19 (COVID-19). Objective: The main objective of this study is to evaluate the prevalence of hyponatremia in COVID-19 patients and to assess the correlation between hyponatremia and severity and outcome of COVID-19. The other objective is to evaluate the correlation between various inflammatory markers and outcome (ICU vs non-ICU admission, discharged vs deceased) in patients with COVID-19 pneumonia. Methods: A total of 113 participants who have been diagnosed with COVID-19 infection by reverse transcriptase-polymerase chain reaction test were included in the study. Epidemiological, demographic, clinical, investigative work-up, and outcome data were extracted from electronic health records using a standard data collection form. Based on serum sodium levels, patients were divided into two groups: normonatremic (serum Na+ ≥ 135 mEq/L) and hyponatremic (serum Na+ < 135 mEq/L). Various clinical, laboratory, and outcome parameters were compared between the two groups. Results: Hyponatremia was present in 50 out of 113 (44%) patients in our study, and it was generally mild. There were more male patients in hyponatremia group ( P = .006), and hyponatremic patients were older than normonatremic patients ( P = .001). Forty (35%) of the 113 patients were transferred to the ICU, and 17 (15%) needed mechanical ventilation during their hospitalization. Interleukin-6 (IL-6) levels were higher in the hyponatremic group ( P = .022). Intensive care unit admissions and oxygen requirement were significantly higher in hyponatremic patients ( P = .001 and .016, respectively). Ferritin, lactate dehydrogenase (LDH), IL-6, total leucocyte count, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) levels were significantly elevated in those patients requiring ICU admission and those who died due to COVID-19. Conclusions: Our study revealed that demography, clinical features, radiographic findings, complications like renal insufficiency, and inflammatory markers like IL-6 play a considerable role in hyponatremic COVID-19 patients. Hyponatremia patients required significantly higher rates of ICU admissions and oxygen support. Our results suggest that monitoring inflammatory markers such as ESR, CRP, total white blood cell (WBC) count, ferritin, LDH, and IL-6 may serve as an early warning system for progression to severe COVID-19.

25 Hydroxyvitamin D

We aimed to examine whether low intensive care unit (ICU) admission 25-hydroxyvitamin D (25(OH)D) levels are associated with worse outcomes of COVID-19 pneumonia. This was a prospective observational study of SARS-CoV2 positive critically ill patients treated in a multidisciplinary ICU. Thirty (30) Greek patients were included, in whom 25(OH)D was measured on ICU admission. Eighty (80%) percent of patients had vitamin D deficiency, and the remaining insufficiency. Based on 25(OH)D levels, patients were stratified in two groups: higher and lower than the median value of the cohort (15.2 ng/mL). The two groups did not differ in their demographic or clinical characteristics. All patients who died within 28 days belonged to the low vitamin D group. Survival analysis showed that the low vitamin D group had a higher 28-day survival absence probability (log-rank test, p = 0.01). Critically ill COVID-19 patients who died in the ICU within 28 days appeared to have lower ICU admission 25(OH)D levels compared to survivors. When the cohort was divided at the median 25(OH)D value, the low vitamin D group had an increased risk of 28-day mortality. It seems plausible, therefore, that low 25(OH)D levels may predispose COVID-19 patients to an increased 28-day mortality risk.

Abstract Background There are limited data on Coronavirus Disease 2019 (COVID-19) outcomes at a national level, and none after 60 days of follow up. The aim of this study was to describe national, 60-day all-cause mortality associated with COVID-19, and to identify risk factors associated with admission to an intensive care unit (ICU). Methods This was a retrospective cohort study including the first consecutive 5000 patients with COVID-19 in Qatar who completed 60 days of follow up by June 17, 2020. The primary outcome was all-cause mortality at 60 days after COVID-19 diagnosis. In addition, we explored risk factors for admission to ICU. Results Included patients were diagnosed with COVID-19 between February 28 and April 17, 2020. The majority (4436, 88.7%) were males and the median age was 35 years [interquartile range (IQR) 28–43]. By 60 days after COVID-19 diagnosis, 14 patients (0.28%) had died, 10 (0.2%) were still in hospital, and two (0.04%) were still in ICU. Fatal COVID-19 cases had a median age of 59.5 years (IQR 55.8–68), and were mostly males (13, 92.9%). All included pregnant women (26, 0.5%), children (131, 2.6%), and healthcare workers (135, 2.7%) were alive and not hospitalized at the end of follow up. A total of 1424 patients (28.5%) required hospitalization, out of which 108 (7.6%) were admitted to ICU. Most frequent co-morbidities in hospitalized adults were diabetes (23.2%), and hypertension (20.7%). Multivariable logistic regression showed that older age [adjusted odds ratio (aOR) 1.041, 95% confidence interval (CI) 1.022–1.061 per year increase; P < 0.001], male sex (aOR 4.375, 95% CI 1.964–9.744; P < 0.001), diabetes (aOR 1.698, 95% CI 1.050–2.746; P 0.031), chronic kidney disease (aOR 3.590, 95% CI 1.596–8.079, P 0.002), and higher BMI (aOR 1.067, 95% CI 1.027–1.108 per unit increase; P 0.001), were all independently associated with increased risk of ICU admission. Conclusions In a relatively younger national cohort with a low co-morbidity burden, COVID-19 was associated with low all-cause mortality. Independent risk factors for ICU admission included older age, male sex, higher BMI, and co-existing diabetes or chronic kidney disease.

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.

Objective: Evaluate the relation of nursing workload, evaluated by the Nursing Activities Score (NAS), with the occurrence of Ventilator-associated Pneumonia (VAP) in an Intensive Care Unit (ICU) and the impact of VAP on hospitalization costs.Methods: Retrospective cohort study in Adult ICU of a high complexity Brazilian university hospital. The profile, outcomes, costs, and daily NAS from patients were collected. We also proposed some workload indicators based on NAS daily evaluation.Results: The study included 195 patients, 27.17% diagnosed with VAP. VAP was more prevalent in patients diagnosed with trauma on admission. The total costs of care were higher for VAP patients. In all multivariate models tested were predictive for VAP: the patient's intubation that occurs in days prior of the ICU admission day (higher risk if occurs in days prior the ICU admission day) and ventilation time prior ICU (higher risk if higher time). We found others predictors, but these were dependent on the model tested. Additional risk predictors were tracheostomy, propofol use, neuromuscular blocker use and the higher NAS from admission. The protective factors found were the percentage of adequacy of the assignment based in NAS that measure if the workload measured by the NAS was offered and the increment in NAS during the ventilation time.Conclusions: The offering of an adequate nursing work scale (adequate number of professionals for the care), as a function of the nursing workload measured by the NAS, could be effective in the reduction of VAP, hospital stay time and hospital costs.

Abstract Background Numerous studies have shown that exposure to air pollution, especially particulate matter (PM) with a diameter <2.5 μm (PM2.5), was associated with various diseases. We tried to determine the impact of PM2.5 and other weather factors on acute lung edema in patients with Stage 5 nondialysis chronic kidney disease (CKD Stage 5-ND). Methods In total, 317 CKD Stage 5-ND (estimated glomerular filtration rate 6.79 ± 4.56 mL/min) patients residing in central Taiwan who developed acute lung edema and initiated long-term dialysis were included in this case-crossover study. Pearson’s correlation test was used to examine the relationship of acute lung edema cases with PM2.5 levels and ambient temperature separately. Results The average PM2.5 level within the 7-day period correlated with acute lung edema incidence in the fall [adjusted odds ratio (OR) 3.23, P = 0.047] and winter (adjusted OR 1.99, P < 0.001). In winter, even a 3-day exposure to PM2.5 was associated with increased risk (adjusted OR 1.55, P < 0.001). The average temperatures within 3 days in spring and summer were correlated positively with the risk (adjusted OR 2.77 P < 0.001 and adjusted OR 2.72, P < 0.001, respectively). In the fall and winter, temperatures were correlated negatively with the risk (adjusted OR 0.36, P < 0.001 and adjusted OR 0.54, P < 0.001, respectively). Conclusions A high PM2.5 level was associated with an increased risk of acute lung edema. High ambient temperature in hot seasons and low ambient temperature in cold seasons were also associated with increased risk. It is essential to educate these patients to avoid areas with severe air pollution and extreme ambient temperature.
