Background: Multisystem Inflammatory Syndrome in Children (MIS-C) is a recently identified entity in association with COVID-19. Acute kidney injury (AKI) has been widely reported in patients with primary COVID-19 infection. However, there is a paucity of literature regarding renal injury in MIS-C. We aim to characterize AKI in MIS-C in this cohort identified at a major children's hospital in New York City during the COVID-19 pandemic. Methods: We conducted a retrospective cohort study of children 0-20 years old admitted to Morgan Stanley Children's Hospital (MSCH) between April 18th and September 23rd, 2020. Patients were included if they met criteria for MIS-C based on CDC guidelines. All patients were evaluated for the presence of AKI, and AKI was staged according to KDIGO criteria. Results: Of the 57 children who met inclusion criteria, 46% (26/57) were found to have AKI. The majority of patients, 58% (15/26), were classified as KDIGO Stage 1. AKI was present upon admission in 70% of those identified. All patients had resolution of AKI at discharge, with 61% achieving recovery by day 2. One patient required dialysis. When compared to those without renal injury, the AKI cohort was older (p < 0.001) and with higher median peak values of CRP (p <0.001), IL-6 (p <0.05), ferritin (p < 0.001), and procalcitonin (p <0.05). More patients with AKI had left ventricular systolic dysfunction (p < 0.001) and lymphopenia (p <0.01), when compared to those without AKI. No differences in Body Mass Index or sex were found. Conclusion: While children with MIS-C may develop AKI, our study suggests most experience mild disease, swift resolution, and promising outcome. Older age, increased inflammation, and left ventricular systolic dysfunction may be risk factors. Our study highlights the substantial differences in epidemiology and outcomes between AKI associated with pediatric MIS-C versus primary COVID-19 infection.

Abstract Background Heart failure (HF) is a major health problem. Cardiac and renal diseases interact in a complex bidirectional manner in both acute and chronic settings. Renal dysfunction in the setting of heart failure, termed the cardio renal syndrome (CRS), has been considered consequence of left ventricular dysfunction (LVD), whereby decreasing cardiac output (COP) results in renal under perfusion and consequent decreased glomerular filtration rate (GFR). Main body of the abstract This study showed that 500 patients were admitted to internal care unit (ICU), and out of them, 100 (20%) patients developed acute kidney injury (AKI) while 400 (80%) patients did not develop AKI. It is also showed that 67 (67%) of those with AKI and 100 (25%) of those with no-AKI had baseline ventricular systolic dysfunction, left ventricular dysfunction (LVD), right ventricular dysfunction (RVD), and biventricular dysfunction (BiVD)presented in 23 (23%), 16 (16%), and 28 (28%) patients of AKI group, respectively, and presented in 60 (15%), 30 (7.50%), and 10 (2.50%) patients, respectively, in patients without acute kidney injury (AKI) Short conclusion Our study revealed that AKI has highest incidence in patient with biventricular dysfunction followed by left ventricular dysfunction and lastly those with right ventricular dysfunction.

Cardiac manifestations in multisystem inflammatory syndrome in children (MIS-C) can include coronary artery aneurysms, left ventricular systolic dysfunction, and electrocardiographic disturbances. We report the clinical course of three children with MIS-C while focusing on the unique considerations for managing atrioventricular conduction abnormalities. All initially had normal electrocardiograms but developed bradycardia followed by either PR prolongation or QTc elongation. Two had mild left ventricular ejection fraction dysfunction prior to developing third-degree heart block and/or a junctional escape rhythm; one had moderate left ventricular systolic dysfunction that normalized before developing a prolonged QTc. On average, our patients presented to the hospital 4 days after onset of illness. Common presenting symptoms included fevers, abdominal pain, nausea, and vomiting. Inflammatory and coagulation factors were their highest early on, and troponin peaked the highest within the first two days; meanwhile, peak brain-natriuretic peptide occurred at hospital days 3-4. The patient’s lowest left ventricular ejection fraction occurred at days 5-6 of illness. Initial electrocardiograms were benign with PR intervals below 200 milliseconds (ms); however, collectively the length of time from initial symptom presentation till when electrocardiographic abnormalities began was approximately days 8-9. When comparing the timing of electrocardiogram changes with trends in c-reactive protein and brain-natriuretic peptide, it appeared that the PR and QTc elongation patterns occurred after the initial hyperinflammatory response. This goes in line with the proposed mechanism that such conduction abnormalities occur secondary to inflammation and edema of the conduction tissue as part of a widespread global myocardial injury process. Based on this syndrome being a hyperinflammatory response likely affecting conduction tissue, our group was treated with different regimens of intravenous immunoglobulin, steroids, anakinra, and/or tocilizumab. These medications were successful in treating third-degree heart block, prolonged QTc, and a junctional ectopic rhythm.
