Background and Objectives: The severity and mortality of coronavirus disease 19 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 are positively associated with underlying diseases such as hypertension, diabetes, and chronic kidney disease (CKD). In this regard, the current study aimed to evaluate the clinical characteristics, laboratory findings, and outcomes of coronavirus disease 2019 (COVID-19) hospitalized patients with and without CKD. Methods: This cross-sectional matched study was conducted on hospitalized confirmed COVID-19 patients with and without CKD admitted to Baqiyatallah Hospital in Tehran, Iran, from February 26, 2020 to March 26, 2020. The patients were homogenized in terms of age, gender, body mass index, and underlying diseases such as hypertension and diabetes. Demographic data, clinical symptoms, and laboratory and radiological findings were collected from patients' medical records and compared between the patients based on their CKD status. Results: Among the COVID-19 patients, 56 and 97 cases with and without CKD were investigated, respectively. In general, 111 (72.5%) patients with a mean age of 55 years were males. Patients with CKD had higher levels of blood urea nitrogen, creatinine, and red cell distribution width (p<0.05). No differences were found regarding chest computed tomography findings, ICU admission, and death among COVID-19 patients with and without CKD. Conclusions: Overall, the findings support the use of red cell distribution width, blood urea nitrogen, and creatinine for monitoring the COVID-19 patients with CKD and assessing the risk of disease progression. Eventually, managing comorbidities including hypertension and diabetes will reduce COVID-19 severity in CKD patients.

Purpose Coronavirus disease 2019 (COVID-19) has a higher mortality in the presence of chronic kidney disease (CKD). However, there has not been much research in the literature concerning the outcomes of CKD patients in the post-COVID-19 period. We aimed to investigate the outcomes of CKD patients not receiving renal replacement therapy. Methods In this multicenter observational study, we included CKD patients with a GFR < 60 ml/min/1.73 m 2 who survived after confirmed COVID-19. Patients with CKD whose kidney disease was due to diabetic nephropathy, polycystic kidney disease and glomerulonephritis were not included in this study. CKD patients with similar characteristics, who did not have COVID-19 were included as the control group. Results There were 173 patients in the COVID-19 group and 207 patients in the control group. Most patients (72.8%) were treated as inpatient in the COVID-19 group (intensive care unit hospitalization: 16.7%, acute kidney injury: 54.8%, needing dialysis: 7.9%). While there was no significant difference between the baseline creatinine values of the COVID-19 group and the control group (1.86 and 1.9, p = 0.978, respectively), on the 1st month, creatinine values were significantly higher in the COVID-19 group (2.09 and 1.8, respectively, p = 0.028). Respiratory system symptoms were more common in COVID-19 patients compared to the control group in the 1st month and 3rd month follow-ups (p < 0.001). Mortality at 3 months after the diagnosis of COVID-19 was significantly higher in the COVID-19 group than in the control group (respectively; 5.2% and 1.4%, p:0.037). Similarly, the rate of patients requiring dialysis for COVID-19 was significantly higher than the control group (respectively; 8.1% and 3.4%, p: 0.045). Conclusions In CKD patients, COVID-19 was associated with increased mortality, as well as more deterioration in kidney function and higher need for dialysis in the post-COVID-19 period. These patients also had higher rate of ongoing respiratory symptoms after COVID-19.
CHRONIC KIDNEY DISEASE AND MORTALITY FROM COVID-19: A LITERATURE REVIEW (Atena Editora)
CHRONIC KIDNEY DISEASE AND MORTALITY FROM COVID-19: A LITERATURE REVIEW (Atena Editora), 2022
An outbreak of COVID-19 occurred in Wuhan, Hubei Province, China in December 2019 and was declared a global pandemic by the World Health Organization. COVID-19 is highly contagious through person-to-person transmission and can cause critical illness and until the death. There have been over 250 million confirmed cases and over 5 million deaths as of November 15, 2021. Recent clinical evidence has revealed that COVID-19 patients with Acute Kidney Injury have had fatal outcomes. This implies the lives of patients with pre-existing Chronic Kidney Disease. The aim of the present study will be to assess the influence of pre-existing CKD on the risks of all-cause mortality, hospitalization and critical condition among patients with COVID-19 infection. An integrative literature review will be carried out in PubMed, Embase and Cochrane Library databases. The following will be used as inclusion criteria for the selection of articles: articles published within the time frame (2020-2021) and in the English language. It is expected to note that Chronic Kidney Disease may be associated with an increased risk of severe COVID-19 infection. Finally, it is expected that the presence of CKD must be considered an important factor in future risk stratification models for COVID-19.
COVID-19 in chronic kidney disease: a retrospective, propensity score-matched cohort study
International Urology and Nephrology, 2021
Background The prognostic factors for COVID-19 in patients with chronic kidney disease (CKD) are uncertain. We conducted a study to compare clinical and prognostic features between hospitalized COVID-19 patients with and without CKD. Methods Fifty-six patients with stage 3-5 CKD and propensity score-matched fifty-six patients without CKD were included in the study. Patients were followed-up at least fifteen days or until death after COVID-19 diagnosis. The endpoints were death from all causes, development of acute kidney injury (AKI) or cytokine release syndrome or respiratory failure, or admission to the intensive care unit (ICU). Results All patients were reviewed retrospectively over a median follow-up of 44 days (IQR, 36-52) after diagnosis of COVID-19. Patients with CKD had higher intensive care unit admission and mortality rates than the patients without CKD, but these results did not reach statistical significance (16 vs. 19; p = 0.54 and 11 vs. 16, p = 0.269, respectively). The frequency of AKI development was significantly higher in predialysis patients with CKD compared to the other group (8 vs. 5; p < 0.001), but there was no significant difference between the groups in terms of cytokine release syndrome (13 vs. 8; p = 0.226), follow-up in the ICU (19 vs. 16; p = 0.541), and respiratory failure (25 vs. 22, p = 0.566). Multivariate logistic regression analysis revealed that respiratory failure and AKI were independent risk factors for mortality. Conclusion The mortality rates of COVID-19 patients with CKD had higher than COVID-19 patients without CKD. Also, AKI and respiratory failure were independently related to mortality.
Acute Kidney Disease and Mortality in Acute Kidney Injury Patients with COVID-19
Journal of Clinical Medicine, 2021
Background: The incidence of AKI in coronavirus disease 2019 (COVID-19) patients is variable and has been associated with worse prognosis. A significant number of patients develop persistent kidney damage defined as Acute Kidney Disease (AKD). There is a lack of evidence on the real impact of AKD on COVID-19 patients. We aim to identify risk factors for the development of AKD and its impact on mortality in COVID-19 patients. Methods: Retrospective analysis of COVID-19 patients with AKI admitted at the Centro Hospitalar Universitário Lisboa Norte between March and August of 2020. The Kidney Disease Improving Global Outcomes (KDIGO) classification was used to define AKI. AKD was defined by presenting at least KDIGO Stage 1 criteria for >7 days after an AKI initiating event. Results: In 339 COVID-19 patients with AKI, 25.7% patients developed AKD (n = 87). The mean age was 71.7 ± 17.0 years, baseline SCr was 1.03 ± 0.44 mg/dL, and the majority of patients were classified as KDIGO st...

Background Chronic kidney disease (CKD) is a risk factor for death from coronavirus disease 2019 (COVID-19), and COVID-19 may cause acute kidney injury (AKI) which also influences outcomes. There is little information on the independent contribution of CKD and AKI to the risk of death in COVID-19 on different waves, as CKD is a key risk factor for AKI. Methods We have studied the epidemiology of CKD and AKI in 2878 patients hospitalized for COVID-19 and their independent association with in-hospital mortality in the two largest pre-vaccination COVID-19 waves in Madrid, Spain. Hospitalized COVID-19 patients were grouped into four mutually exclusive categories: previous-CKD, community-acquired AKI (CA-AKI), hospital-acquired AKI (HA-AKI) and normal renal function throughout hospitalization. Results Pre-existent or acquired kidney involvement was observed in 35.5% and 36.8% of COVID-19 patients in the 1st and 3rd waves, respectively. Overall, 13.9% of patients with normal kidney functi...

Background: Coronavirus disease 2019 (COVID-19) disproportionately affects individuals with various comorbidities. Among these, chronic kidney disease (CKD) has been shown to be strongly associated with the progression to severe disease. This study aimed to assess the severity and disease outcomes in patients with COVID-19 infection and CKD. Methods: This is a retrospective study conducted at a tertiary care hospital from July 2021 to September 2021. The case records of patients with CKD and COVID-19 were studied. They were compared with age and gender-matched controls equally. The presenting symptoms, clinical course, severity of illness, laboratory markers, need for ventilator support, and mortality outcomes were studied. Results: In total, 40 CKD and 40 non-CKD patients with COVID-19 were included in the study. It was also observed that among the patients with CKD, more patients had fever, breathlessness, and diarrhea. The requirement for noninvasive ventilation, ventilator, and inotropes was on the higher average for patients with CKD. Overall mortality was 27.5% in the CKD group and 2.5% in the non-CKD group, which was statistically significant (p = 0.002). Conclusions: COVID-19 patients with CKD had more severe illnesses with a requirement of ventilator support and had higher mortality than the patients without CKD. Patients with CKD are a key subset of patients with COVID-19 for whom more aggressive early treatment and stricter preventive measures may be beneficial.

Background Acute kidney injury (AKI) is common in coronavirus disease 2019 (COVID-19). This study investigated adults hospitalized with COVID-19 and hypothesized that risk factors for AKI would include comorbidities and non-White race. Methods A prospective multicentre cohort study was performed using patients admitted to 254 UK hospitals with COVID-19 between 17 January 2020 and 5 December 2020. Results Of 85 687 patients, 2198 (2.6%) received acute kidney replacement therapy (KRT). Of 41 294 patients with biochemistry data, 13 000 (31.5%) had biochemical AKI: 8562 stage 1 (65.9%), 2609 stage 2 (20.1%) and 1829 stage 3 (14.1%). The main risk factors for KRT were chronic kidney disease (CKD) [adjusted odds ratio (aOR) 3.41: 95% confidence interval 3.06–3.81], male sex (aOR 2.43: 2.18–2.71) and Black race (aOR 2.17: 1.79–2.63). The main risk factors for biochemical AKI were admission respiratory rate >30 breaths per minute (aOR 1.68: 1.56–1.81), CKD (aOR 1.66: 1.57–1.76) and Black...

Coronavirus disease 19 (COVID-19) has affected over 180 countries, resulting in global mass death. It has been reported that patients with underlying disease are more likely to contract the disease and become critically ill. The impact of chronic kidney disease (CKD) on the severity of COVID-19 has been underlined in the literature. In this analysis, we have provided evidence of an association between CKD and COVID-19. We followed the PRISMA protocol and conducted a literature search using Google Scholar, EMBASE, PubMed, and Clinical trail.gov. The initial search yielded 2102 articles. We included 20 cohorts based on inclusion criteria reporting an association between CKD and COVID-19 after excluding irrelevant articles, including review articles and duplicates. We conducted pooled prevalence of CKD and meta-analysis to estimate the odds ratio (OR), 95% confidence interval (CI) using Cochrane RevMan (version 5.4, Copenhagen: The Nordic Cochrane Centre, The Cochrane Collaboration), and R programming language version 4.16-2 (University of Auckland, New Zealand). Our study involved 4350 patients from different countries, and 212 (4.9%) patients had CKD. Among 20 cohorts, 57.27% were male with a median age of 55.5 years. Eight hundred sixty-six patients developed severe COVID-19, and out of which, 39 (4.5%) were CKD patients. CKD patients had a significantly increased risk of severe disease as compared to non-CKD patients with a pooled OR of 2.15 (95% CI 1.16-4.01) (I 2 =41; p=0.02). Out of 443 COIVD-19 patients who died, 85 patients had CKD, with a prevalence of 19.18%. CKD patients had an increased risk of death as compared to non-CKD patients with a pooled OR of 5.58 (95% CI 3.27-9.54) (I 2 =0; p<0.00001). CKD is manifested as a common underlying disease in COVID-19 patients who had a worse prognosis, including mortality.

Background/aim: Hospital-acquired acute kidney injury (HA-AKI) may commonly develop in Covid-19 patients and is expected to have higher mortality. There is little comparative data investigating the effect of HA-AKI on mortality of chronic kidney disease (CKD) patients and a control group of general population suffering from Covid-19. Materials and methods: HA-AKI development was assessed in a group of stage 3-5 CKD patients and control group without CKD among adult patients hospitalized for Covid-19. The role of AKI development on the outcome (in-hospital mortality and admission to the intensive care unit [ICU]) of patients with and without CKD was compared. Results: Among 621 hospitalized patients (age 60 [IQR: 47-73]), women: 44.1%), AKI developed in 32.5% of the patients, as stage 1 in 84.2%, stage 2 in 8.4%, and stage 3 in 7.4%. AKI developed in 48.0 % of CKD patients, whereas it developed in 17.6% of patients without CKD. CKD patients with HA-AKI had the highest mortality rate of 41.1% compared to 14.3% of patients with HA-AKI but no CKD (p < 0.001). However, patients with AKI+non-CKD had similar rates of ICU admission, mechanical ventilation, and death rate to patients with CKD without AKI. Adjusted mortality risks of the AKI+non-CKD group (HR: 9.0, 95% CI: 1.9-44.2) and AKI+CKD group (HR: 7.9, 95% CI: 1.9-33.3) were significantly higher than that of the non-AKI+non-CKD group. Conclusion: AKI frequently develops in hospitalized patients due to Covid-19 and is associated with high mortality. HA-AKI has worse outcomes whether it develops in patients with or without CKD, but the worst outcome was seen in AKI+CKD patients.
