Abstract Background Acute kidney injury (AKI) is a recognised complication of coronavirus disease 2019 (COVID-19), yet the reported incidence varies widely and the associated risk factors are poorly understood. Methods Data was collected on all adult patients who returned a positive COVID-19 swab while hospitalised at a large UK teaching hospital between 1st March 2020 and 3rd June 2020. Patients were stratified into community- and hospital-acquired AKI based on the timing of AKI onset. Results Out of the 448 eligible patients with COVID-19, 118 (26.3 %) recorded an AKI during their admission. Significant independent risk factors for community-acquired AKI were chronic kidney disease (CKD), diabetes, clinical frailty score and admission C-reactive protein (CRP), systolic blood pressure and respiratory rate. Similar risk factors were significant for hospital-acquired AKI including CKD and trough systolic blood pressure, peak heart rate, peak CRP and trough lymphocytes during admission. In addition, invasive mechanical ventilation was the most significant risk factor for hospital-acquired AKI (adjusted odds ratio 9.1, p < 0.0001) while atrial fibrillation conferred a protective effect (adjusted odds ratio 0.29, p < 0.0209). Mortality was significantly higher for patients who had an AKI compared to those who didn’t have an AKI (54.3 % vs. 29.4 % respectively, p < 0.0001). On Cox regression, hospital-acquired AKI was significantly associated with mortality (adjusted hazard ratio 4.64, p < 0.0001) while community-acquired AKI was not. Conclusions AKI occurred in over a quarter of our hospitalised COVID-19 patients. Community- and hospital-acquired AKI have many shared risk factors which appear to converge on a pre-renal mechanism of injury. Hospital- but not community acquired AKI was a significant risk factor for death.

Background: Urinary tract infection (UTI) is common and diabetic patients are at increased risk for UTI. UTI may be complicated by acute kidney injury (AKI). This study was designed to evaluate whether UTI due to extend ed-spectrum beta-lactamase (ESBL) producing organisms should be considered as a risk factor for AKI in type 2 diabetic subjects.Methods: This case-control study was done in a tertiary care hospital in Dhaka, Bangladesh from April to June 2016. Type 2 diabetic subjects with culture proven UTI were evaluated. Patients with UTI complicated by AKI were cases and those without AKI were taken as controls. ESBL-positivity of the isolated organisms was evaluated as risk factor for AKI.Results: During the study period, a total of 131 (male to female ratio 1:2.6) type 2 diabetic subjects with culture proven UTI were enrolled. Mean age and mean duration of diabetes were 56.1±13.3 and 8.7±5.4 years respectively. Escherichia coli (82, 62.6%) was the commonest aetiological agent followed by Klebsiella pneumoniae(14, 10.7%). Two-thirds (55/82, 67.1%) of E. coli and two-fifths (6/14, 42.9%) of Klebsiellae were ESBL-positive. UTI in 64 (48.9%) patients were due to ESBL-positive organisms. Out of 131 UTI patients, 62 (47.3%) had AKI; 40 (40/64, 62.5%) among ESBL-positive and 22 (22/67, 32.8%) among non-ESBL organisms. There were no significant difference in relation to age (p=0.71), sex (p=0.26), duration of diabetes (p=0.37) and glycated haemoglobin (HbA1c) (p=0.69) between cases and controls. ESBL-positivity appeared as a significant risk factor for AKI among the study subjects (OR=3.4, 95% CI=1.66-6.99, p=0.008).Conclusions: Almost half of the type 2 diabetic subjects with UTI had ESBL-positive organisms as aetiological agents in this study. UTI due to ESBL-positive organisms was a significant risk factor for AKI.J MEDICINE Jan 2018; 19 (1) : 40-43

Abstract Background Acute kidney injury (AKI) is a frequently encountered clinical condition in critically ill patients and is associated with increased morbidity and mortality. In our resource-limited setting (RLS), the most common cause of AKI is sepsis and volume depletion. Sepsis alone, accounts for up to 62 % of the AKI cases in HIV-positive patients. Objective The major goal of this study was to determine the incidence and risk predictors of AKI among HIV-infected patients admitted with sepsis at a tertiary hospital in Uganda. Methods In a prospective cohort study, we enrolled adult patients presenting with sepsis at Mbarara Regional Referral Hospital (MRRH) in southwestern Uganda between March and July 2020. Sepsis was determined using the qSOFA criteria. Patients presenting with CKD or AKI were excluded. Sociodemographic characteristics, physical examination findings, and baseline laboratory values were recorded in a data collection tool. The serum creatinine and urea were done at admission (0-hour) and at the 48-hour mark to determine the presence of AKI. We performed crude and multivariable binomial regression to establish the factors that predicted developing AKI in the first 48 h of admission. Variables with a p < 0.01 in the adjusted analysis were considered as significant predictors of AKI. Results Out of 384 patients screened, 73 (19 %) met our inclusion criteria. Their median age was 38 (IQR 29–46) years and 44 (60.3 %) were male. The median CD4 T-cell count was 67 (IQR 35–200) cells, median MUAC was 23 (IQR 21–27) cm and 54 (74.0 %) participants were on a regimen containing Tenofovir Disoproxil Fumarate (TDF). The incidence of AKI in 48 h was 19.2 % and in the adjusted analysis, thrombocytopenia (Platelet count < 150) (adjusted risk ratio 8.21: 95 % CI: 2.0–33.8, p = 0.004) was an independent predictor of AKI. Conclusions There is a high incidence of AKI among HIV-positive patients admitted with sepsis in Uganda. Thrombocytopenia at admission may be a significant risk factor for developing AKI. The association of thrombocytopenia in sepsis and AKI needs to be investigated.

Introduction/Objective. Hyperchloremia is often registered in adults? studies after administration with 0.9% sodium chloride, which contributes to the development of acute kidney injury (AKI) as it leads to vasoconstriction of renal blood vessels. The aim of this study was to determine the correlation of sodium and chloride imbalance with the development of AKI, with consideration of other risk factors for this disorder. Methods. This retrospective study included 146 randomly selected preterm infants hospitalized at the Neonatal Intensive Care Unit from 2008 to 2015. Results. Among the patients registered for the study, 23.97% developed AKI, and they were of a significantly lower gestational age (26.3 ? 2.8 weeks vs. 31.7 ? 2.90 weeks, p < 0.05); birth weight (971.31 ? 412.1 g vs. 1,753.3 ? 750.3 g, p < 0.05); Apgar score in the first (3.2 ? 1.7 vs. 5.7 ? 2.4, p < 0.05) and fifth minute (5.3 ? 1.7 vs. 7.1 ? 1.8, p < 0.05) of life compared to those without AKI. The neonates with AKI had significantly higher maximum chloremia (Clmax: 114.1 ? 8.4 vs. 111.7 ? 4.6, p = 0.029) and maximum natremia (Namax: 147.9 ? 8.8 vs. 142.9 ? 4, p < 0.05). Each of these parameters is (independently) a statistically significant risk factor for the development of AKI, and gestational age is the strongest (OR = 1 / 0.643 = 1.55; 95% CI 1.24?1.94). Mortality in neonates with AKI was higher than in neonates without AKI (19.4% vs. 92.7%, p < 0.05). Conclusion. Hyperchloremia and hypernatremia are more common in the premature newborns with AKI compared to the premature newborns without AKI. Higher maximum sodium and chloride values are independent risk factors for AKI.

Abstract Background The effects of vitamin C on clinical outcomes in critically ill patients remain controversial due to inconclusive studies. This retrospective observational cohort study evaluated the effects of vitamin C therapy on acute kidney injury (AKI) and mortality among septic patients. Methods Electronic medical records of 1390 patients from an academic hospital who were categorized as Treatment (received at least one dose of 1.5 g IV vitamin C, n = 212) or Comparison (received no, or less than 1.5 g IV vitamin C, n = 1178) were reviewed. Propensity score matching was conducted to balance a number of covariates between groups. Multivariate logistic regressions were conducted predicting AKI and in-hospital mortality among the full sample and a sub-sample of patients seen in the ICU. Results Data revealed that vitamin C therapy was associated with increases in AKI (OR = 2.07 95% CI [1.46–2.93]) and in-hospital mortality (OR = 1.67 95% CI [1.003–2.78]) after adjusting for demographic and clinical covariates. When stratified to examine ICU patients, vitamin C therapy remained a significant risk factor of AKI (OR = 1.61 95% CI [1.09–2.39]) and provided no protective benefit against mortality (OR = 0.79 95% CI [0.48–1.31]). Conclusion Ongoing use of high dose vitamin C in sepsis should be appraised due to observed associations with AKI and death.

Introduction: In Brazil, primary studies on this issue are still limited and the ideal timing of initiation of dialysis in severe acute kidney injury (AKI) still generates disagreements among experts. Objectives: To assess if the timing of initiation of dialysis is associated with the mortality of patients with AKI in intensive care unit (ICU). Patients and Methods: We retrospectively analyzed medical records of patients that developed severe AKI in the ICU. Bivariate analysis was carried out to compare data between groups of patients who underwent early dialysis (ED - initiated up to two days after the AKI diagnosis) and late dialysis (LD – initiated more than two days after the AKI diagnosis), while multivariate logistic regression was applied to identify factors associated with mortality. Results: Of the 76 patients included in the study, 27 (35.5%) were allocated in the ED group and 49 (64.5%) in the LD group. LD group had a higher frequency of sepsis [26 (53%) vs. 12 (44%); P = 0.472], while the ED group had a higher median number of dialysis sessions (6 vs. 3; P = 0.477) and higher total median time on dialysis (17.5 h vs. 13 h; P = 0.629). The overall mortality rate was 61.8% (n = 47) and of 76% (n = 22) in the ED group. The patients’ serum creatinine level at admission in the ICU was the only statistically significant risk factor for death [OR= 0.453 (95% CI= 0.257–0.801); P = 0.006]. Conclusion: The overall and in the ED group mortality rate was elevated, however, the timing of initiation of dialysis did not show statistically significant association with death. The serum creatinine at ICU admission seems to be an important mortality predictor.

The incidence of acute kidney injury (AKI) in the intensive care unit (ICU) has increased during the past decade due to increased acuity as well as increased recognition. Early epidemiology studies were confounded by erratic definitions of AKI until recent consensus guidelines (RIFLE and AKIN) standardized its definition. This paper discusses the incidence of AKI in the ICU with focuses on specific patient populations. The overall incidence of AKI in ICU patients ranges from 20% to 50% with lower incidence seen in elective surgical patients and higher incidence in sepsis patients. The incidence of contrast-induced AKI is less (11.5%–19% of all admissions) than seen in the ICU population at large. AKI represents a significant risk factor for mortality and can be associated with mortality greater than 50%.
