Item Advances in Neonatal Acute Kidney Injury(AAP, 2021-11) Starr, Michelle C.; Charlton, Jennifer R.; Guillet, Ronnie; Reidy, Kimberly; Tipple, Trent E.; Jetton, Jennifer G.; Kent, Alison L.; Abitbol, Carolyn L.; Ambalavanan, Namasivayam; Mhanna, Maroun J.; Askenazi, David J.; Selewski, David T.; Harer, Matthew W.; Pediatrics, School of MedicineIn this state-of-the-art review, we highlight the major advances over the last 5 years in neonatal acute kidney injury (AKI). Large multicenter studies reveal that neonatal AKI is common and independently associated with increased morbidity and mortality. The natural course of neonatal AKI, along with the risk factors, mitigation strategies, and the role of AKI on short- and long-term outcomes, is becoming clearer. Specific progress has been made in identifying potential preventive strategies for AKI, such as the use of caffeine in premature neonates, theophylline in neonates with hypoxic-ischemic encephalopathy, and nephrotoxic medication monitoring programs. New evidence highlights the importance of the kidney in “crosstalk” between other organs and how AKI likely plays a critical role in other organ development and injury, such as intraventricular hemorrhage and lung disease. New technology has resulted in advancement in prevention and improvements in the current management in neonates with severe AKI. With specific continuous renal replacement therapy machines designed for neonates, this therapy is now available and is being used with increasing frequency in NICUs. Moving forward, biomarkers, such as urinary neutrophil gelatinase–associated lipocalin, and other new technologies, such as monitoring of renal tissue oxygenation and nephron counting, will likely play an increased role in identification of AKI and those most vulnerable for chronic kidney disease. Future research needs to be focused on determining the optimal follow-up strategy for neonates with a history of AKI to detect chronic kidney disease.Item Racial and Ethnic Disparities in Acute Care Utilization Among Patients With Glomerular Disease(Elsevier, 2023) Krissberg, Jill R.; O’Shaughnessy, Michelle M.; Smith, Abigail R.; Helmuth, Margaret E.; Almaani, Salem; Aviles, Diego H.; Brathwaite, Kaye E.; Cai, Yi; Cattran, Daniel; Gbadegesin, Rasheed; Glenn, Dorey A.; Greenbaum, Larry A.; Iragorri, Sandra; Jain, Koyal; Khalid, Myda; Kidd, Jason; Kopp, Jeffrey; Lafayette, Richard; Lane, Jerome C.; Lugani, Francesca; Nestor, Jordan G.; Parekh, Rulan S.; Reidy, Kimberly; Selewski, David T.; Sethna, Christine B.; Sperati, C. John; Tuttle, Katherine; Twombley, Katherine; Vasylyeva, Tetyana L.; Weaver, Donald J., Jr.; Wenderfer, Scott E.; Gibson, Keisha; CureGN Consortium; Pediatrics, School of MedicineRationale & objective: The effects of race, ethnicity, socioeconomic status (SES), and disease severity on acute care utilization in patients with glomerular disease are unknown. Study design: Prospective cohort study. Setting & participants: 1,456 adults and 768 children with biopsy-proven glomerular disease enrolled in the Cure Glomerulonephropathy (CureGN) cohort. Exposure: Race and ethnicity as a participant-reported social factor. Outcome: Acute care utilization defined as hospitalizations or emergency department visits. Analytical approach: Multivariable recurrent event proportional rate models were used to estimate associations between race and ethnicity and acute care utilization. Results: Black or Hispanic participants had lower SES and more severe glomerular disease than White or Asian participants. Acute care utilization rates were 45.6, 29.5, 25.8, and 19.2 per 100 person-years in Black, Hispanic, White, and Asian adults, respectively, and 55.8, 42.5, 40.8, and 13.0, respectively, for children. Compared with the White race (reference group), Black race was significantly associated with acute care utilization in adults (rate ratio [RR], 1.76 [95% CI, 1.37-2.27]), although this finding was attenuated after multivariable adjustment (RR, 1.31 [95% CI, 1.03-1.68]). Black race was not significantly associated with acute care utilization in children; Asian race was significantly associated with lower acute care utilization in children (RR, 0.32 [95% CI 0.14-0.70]); no significant associations between Hispanic ethnicity and acute care utilization were identified. Limitations: We used proxies for SES and lacked direct information on income, household unemployment, or disability. Conclusions: Significant differences in acute care utilization rates were observed across racial and ethnic groups in persons with prevalent glomerular disease, although many of these difference were explained by differences in SES and disease severity. Measures to combat socioeconomic disadvantage in Black patients and to more effectively prevent and treat glomerular disease are needed to reduce disparities in acute care utilization, improve patient wellbeing, and reduce health care costs.
