Background: Acute kidney injury (AKI) is a growing global concern and often reversible. Saliva urea nitrogen (SUN) measured by a dipstick may allow rapid diagnosis. We studied longitudinal agreement between SUN and blood urea nitrogen (BUN) and the diagnostic performance of both. Methods: Agreement between SUN and BUN and diagnostic performance to diagnose AKI severity in AKI patients in the United States and Brazil were studied. Bland-Altman analysis and linear mixed effects models were employed to test the agreement between SUN and BUN. Receiver operating characteristics statistics were used to test the diagnostic performance to diagnose AKI severity. Results: We found an underestimation of BUN by SUN, decreasing with increasing BUN levels in 37 studied patients, consistent on all observation days. The diagnostic performance of SUN (AUC 0.81, 95% CI 0.63-0.98) was comparable to BUN (AUC 0.85, 95% CI 0.71-0.98). Conclusion: SUN reflects BUN especially in severe AKI. It also allows monitoring treatment responses. Video Journal Club ‘Cappuccino with Claudio Ronco' at http://www.karger.com/?doi=445041.

Objective: To identify whether the timing of initiation of continuous renal replacement therapy affects outcome in septic patients with acute kidney injury in term of 28 days mortality. Study Design: Cross sectional analytical study. Place and Duration of Study: This research was conducted at department of Anaesthesiology and critical careunit of the Aga Khan University Hospital, Karachi, from Oct 2018 to Jun 2019. Methodology: The study reviewed all adult patients aged >18 years who developed acute kidney injury afterseptic shock and required continuous renal replacement therapy in surgical intensive care unit. Considering thevalue of blood urea nitrogen, patients were classified into two groups. One was in early group that‟s was defined as blood urea nitrogen value of <100 mg/dl just before continuous renal replacement therapy initiation while the patients who have blood urea nitrogen value of ≥100 mg/dl just prior to continuous renal replacement therapy initiation were classified as late group. Kaplan-Meier survival analysis was performed and median survival was computed. Results: Forty patients were included for analysis. There were thirty patients (75%) in early group in whomcontinuous renal replacement therapy was started with mean blood urea nitrogen of 66 ± 20.2 mg/dL and 10(25%) patients were in late group with mean blood urea nitrogen of 137 ± 28.4 mg/dL. The overall survival ratesin both groups were 49.6%, and 10.4% at 10 and 25 days, respectively. Median survival time was not statisticallysignificant between early and late continuous renal replacement...........

<p><strong>Objective:</strong> Acute kidney injury is an important problem in neonates. We conducted a cross-sectional prospective study to determine normal serum blood urea nitrogen, creatinine reference ranges and ranges of ultrasonographic measurement of kidneys in healthy term newborns.</p><p><br /><strong>Study Design:</strong> Blood samples were collected from total 357 healthy newborns at birth (n=45), 1st (n=30), 3rd (n=61), 7th (n=34), 10th (n=132), 14th (n=36), and 28th (n=19) days of life. Renal ultrasonographic was performed by the same two radiologists on 81 newborns aged 10 days. <br /><strong></strong></p><p><strong>Results:</strong> Serum blood urea nitrogen and creatinine concentrations have reached to the highest level at the first day of life and have returned to cord level at the third day of life. There were gradually decrease in serum blood urea nitrogen and creatinine levels after the first day of life. There were significant difference in both right and left renal length, width, and volumes in terms of gender and these parameters were statistically higher in boys than girls (p&lt;0.05). Birth weight of the boys (3548±539g) was statistically higher than girls (3307±405 g) (p=0.028). There was a positive correlation between birth weight and right (r=0.38, p=0.000) and left kidney volumes (r=0.44, p=0.000).</p><p><strong>Conclusion:</strong> Our findings showed that measured blood urea nitrogen and creatinine levels changed in accordance with postnatal days and there was a positive correlation between kidney volume and birth weight of newborns. We concluded that these findings are important for evaluation of acute kidney injury and for screening of for urinary tract anomalies in neonates</p>

ABSTRACTAimThe aim of this study was to uncover whether kidney diseases were involved in COVID-19 pandemic from a systematic review.MethodsThe studies reported the kidney outcomes in different severity of COVID-19 were included in this study. Standardized mean differences or odds ratios were calculated by employing Review Manager meta-analysis software.ResultsThirty-six trials were included in this systematic review with a total of 6395 COVID-19 patients. The overall effects indicated that the comorbidity of chronic kidney disease (CKD) (OR = 3.28), complication of acute kidney injury (AKI) (OR = 11.02), serum creatinine (SMD = 0.68), abnormal serum creatinine (OR = 4.86), blood urea nitrogen (SMD = 1.95), abnormal blood urea nitrogen (OR = 6.53), received continuous renal replacement therapy (CRRT) (OR = 23.63) was significantly increased in severe group than that in nonsevere group. Additionally, the complication of AKI (OR = 13.92) and blood urea nitrogen (SMD = 1.18) were remarkably elevated in critical group than that in severe group.ConclusionCKD and AKI are susceptible to occur in patients with severe COVID-19. CRRT is applied frequently in severe COVID-19 patients than that in nonsevere COVID-19 patients. The risk of AKI is higher in critical group than that in severe group.

Background Currently, the SARS-CoV-2 promptly spread across China and around the world. However, there are controversies about whether preexisting chronic kidney disease (CKD) and acute kidney injury complication (AKI) are involved in the COVID-19 pandemic. Measurements Studies reported the kidney outcomes in different severity of COVID-19 were included in this study. Standardized mean differences or odds ratios were calculated by employing Review Manager meta-analysis software. Results Thirty-six trials were included in this systematic review with a total of 6395 COVID-19 patients. The overall effects indicated that preexisting CKD (OR = 3.28), complication of AKI (OR = 11.02), serum creatinine (SMD = 0.68), abnormal serum creatinine (OR = 4.86), blood urea nitrogen (SMD = 1.95), abnormal blood urea nitrogen (OR = 6.53), received continuous renal replacement therapy (CRRT) (OR = 23.63) were significantly increased in severe group than that in nonsevere group. Additionally, the complication of AKI (OR = 13.92) and blood urea nitrogen (SMD = 1.18) were remarkably elevated in the critical group than that in the severe group. Conclusions CKD and AKI are susceptible to occur in patients with severe COVID-19. CRRT is applied frequently in severe COVID-19 patients than that in nonsevere COVID-19 patients. The risk of AKI is higher in the critical group than that in the severe group.
