Item Acute Kidney Injury Defined by Fluid-Corrected Creatinine in Premature Neonates(American Medical Association, 2023-08-01) Starr, Michelle C.; Griffin, Russell L.; Harer, Matthew W.; Soranno, Danielle E.; Gist, Katja M.; Segar, Jeffrey L.; Menon, Shina; Gordon, Lindsey; Askenazi, David J.; Selewski, David T.; Pediatrics, School of MedicineImportance: Acute kidney injury (AKI) and disordered fluid balance are common in premature neonates; a positive fluid balance dilutes serum creatinine, and a negative fluid balance concentrates serum creatinine, both of which complicate AKI diagnosis. Correcting serum creatinine for fluid balance may improve diagnosis and increase diagnostic accuracy for AKI. Objective: To determine whether correcting serum creatinine for fluid balance would identify additional neonates with AKI and alter the association of AKI with short-term and long-term outcomes. Design, setting, and participants: This study was a post hoc cohort analysis of the Preterm Erythropoietin Neuroprotection Trial (PENUT), a phase 3, randomized clinical trial of erythropoietin, conducted at 19 academic centers and 30 neonatal intensive care units in the US from December 2013 to September 2016. Participants included extremely premature neonates born at less than 28 weeks of gestation. Data analysis was conducted in December 2022. Exposure: Diagnosis of fluid-corrected AKI during the first 14 postnatal days, calculated using fluid-corrected serum creatinine (defined as serum creatinine multiplied by fluid balance [calculated as percentage change from birth weight] divided by total body water [estimated 80% of birth weight]). Main outcomes and measures: The primary outcome was invasive mechanical ventilation on postnatal day 14. Secondary outcomes included death, hospital length of stay, and severe bronchopulmonary dysplasia (BPD). Categorical variables were analyzed by proportional differences with the χ2 test or Fisher exact test. The t test and Wilcoxon rank sums test were used to compare continuous and ordinal variables, respectively. Odds ratios (ORs) and 95% CIs for the association of exposure with outcomes of interest were estimated using unconditional logistic regression models. Results: A total of 923 premature neonates (479 boys [51.9%]; median [IQR] birth weight, 801 [668-940] g) were included, of whom 215 (23.3%) received a diagnosis of AKI using uncorrected serum creatinine. After fluid balance correction, 13 neonates with AKI were reclassified as not having fluid-corrected AKI, and 111 neonates previously without AKI were reclassified as having fluid-corrected AKI (ie, unveiled AKI). Therefore, fluid-corrected AKI was diagnosed in 313 neonates (33.9%). Neonates with unveiled AKI were similar in clinical characteristics to those with AKI whose diagnoses were made with uncorrected serum creatinine. Compared with those without AKI, neonates with unveiled AKI were more likely to require ventilation (81 neonates [75.0%] vs 254 neonates [44.3%] and have longer hospital stays (median [IQR], 102 [84-124] days vs 90 [71-110] days). In multivariable analysis, a diagnosis of fluid-corrected AKI was associated with increased odds of adverse clinical outcomes, including ventilation (adjusted OR, 2.23; 95% CI, 1.56-3.18) and severe BPD (adjusted OR, 2.05; 95% CI, 1.15-3.64). Conclusions and relevance: In this post hoc cohort study of premature neonates, fluid correction increased the number of premature neonates with a diagnosis of AKI and was associated with increased odds of adverse clinical outcomes, including ventilation and BPD. Failing to correct serum creatinine for fluid balance underestimates the prevalence and impact of AKI in premature neonates. Future studies should consider correcting AKI for fluid balance.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 Association of Fluid Balance With Short- and Long-term Respiratory Outcomes in Extremely Premature Neonates: A Secondary Analysis of a Randomized Clinical Trial(American Medical Association, 2022-12-01) Starr, Michelle C.; Griffin, Russell; Gist, Katja M.; Segar, Jeffrey L.; Raina, Rupesh; Guillet, Ronnie; Nesargi, Saudamini; Menon, Shina; Anderson, Nekayla; Askenazi, David J.; Selewski, David T.; Pediatrics, School of MedicineImportance: Extremely low gestational age neonates are at risk of disorders of fluid balance (FB), defined as change in fluid weight over a specific period. Few data exist on the association between FB and respiratory outcomes in this population. Objective: To describe FB patterns and evaluate the association of FB with respiratory outcomes in a cohort of extremely low gestational age neonates. Design, setting, and participants: This study is a secondary analysis of the Preterm Erythropoietin Neuroprotection Trial (PENUT), a phase 3 placebo-controlled randomized clinical trial of erythropoietin in extremely premature neonates conducted in 30 neonatal intensive care units in the US from December 1, 2013, to September 31, 2016. This analysis included 874 extremely premature neonates born at 24 to 27 weeks' gestation who were enrolled in the PENUT study. Secondary analysis was performed in November 2021. Exposures: Primary exposure was peak FB during the first 14 postnatal days. The FB was calculated as percent change in weight from birth weight (BW) as a surrogate for FB. Main outcomes and measures: The primary outcome was mechanical ventilation on postnatal day 14. The secondary outcome was a composite of severe bronchopulmonary dysplasia (BPD) or death. Results: A total of 874 neonates (449 [51.4%] male; mean [SD] BW, 801 [188] g; 187 [21.4%] Hispanic, 676 [77.3%] non-Hispanic, and 11 [1.3%] of unknown ethnicity; 226 [25.9%] Black, 569 [65.1%] White, 51 [5.8%] of other race, and 28 [3.2%] of unknown race) were included in this analysis. Of these 874 neonates, 458 (52.4%) received mechanical ventilation on postnatal day 14, and 291 (33.3%) had severe BPD or had died. Median peak positive FB was 11% (IQR, 4%-20%), occurring on postnatal day 13 (IQR, 9-14). A total of 93 (10.6%) never decreased below their BW. Neonates requiring mechanical ventilation at postnatal day 14 had a higher peak FB compared with those who did not require mechanical ventilation (15% above BW vs 8% above BW, P < .001). On postnatal day 3, neonates requiring mechanical ventilation were more likely to have a higher FB (5% below BW vs 8% below BW, P < .001). The median time to return to BW was shorter in neonates who received mechanical ventilation (7 vs 8 days, P < .001) and those with severe BPD (7 vs 8 days, P < .001). After adjusting for confounding variables, for every 10% increase in peak FB during the first 14 postnatal days, there was 103% increased odds of receiving mechanical ventilation at postnatal day 14 (adjusted odds ratio, 2.03; 95% CI, 1.64-2.51). Conclusions and relevance: In this secondary analysis of a randomized clinical trial, peak FB was associated with mechanical ventilation on postnatal day 14 and severe BPD or death. Fluid balance in the first 3 postnatal days and time to return to BW may be potential targets to help guide management and improve respiratory outcomes.Item Clinical Characteristics and Treatment Patterns of Children and Adults With IgA Nephropathy or IgA Vasculitis: Findings From the CureGN Study(Elsevier, 2018-08-03) Selewski, David T.; Ambruzs, Josephine M.; Appel, Gerald B.; Bomback, Andrew S.; Matar, Raed Bou; Cai, Yi; Cattran, Daniel C.; Chishti, Aftab S.; D’Agati, Vivette D.; D’Alessandri-Silva, Cynthia J.; Gbadegesin, Rasheed A.; Hogan, Jonathan J.; Iragorri, Sandra; Jennette, J.

John; Sreedharan, Rajasree; Srivastava, Tarak; Swiatecka-Urban, Agnieszka; Twombley, Katherine; Vasylyeva, Tetyana L.; Weaver, Donald J.; Yin, Hong; Zee, Jarcy; Falk, Ronald J.; Gharavi, Ali G.; Gillespie, Brenda W.; Gipson, Debbie S.; Greenbaum, Larry A.; Holzman, Lawrence B.; Kretzler, Matthias; Robinson, Bruce M.; Smoyer, William E.; Flessner, Michael; Guay-Woodford, Lisa M.; Kiryluk, Krzysztof; CureGN Consortium; Pediatrics, School of MedicineIntroduction: The Cure Glomerulonephropathy Network (CureGN) is a 66-center longitudinal observational study of patients with biopsy-confirmed minimal change disease, focal segmental glomerulosclerosis, membranous nephropathy, or IgA nephropathy (IgAN), including IgA vasculitis (IgAV). This study describes the clinical characteristics and treatment patterns in the IgA cohort, including comparisons between IgAN versus IgAV and adult versus pediatric patients. Methods: Patients with a diagnostic kidney biopsy within 5 years of screening were eligible to join CureGN. This is a descriptive analysis of clinical and treatment data collected at the time of enrollment. Results: A total of 667 patients (506 IgAN, 161 IgAV) constitute the IgAN/IgAV cohort (382 adults, 285 children). At biopsy, those with IgAV were younger (13.0 years vs. 29.6 years, P < 0.001), more frequently white (89.7% vs. 78.9%, P = 0.003), had a higher estimated glomerular filtration rate (103.5 vs. 70.6 ml/min per 1.73 m2, P < 0.001), and lower serum albumin (3.4 vs. 3.8 g/dl, P < 0.001) than those with IgAN. Adult and pediatric individuals with IgAV were more likely than those with IgAN to have been treated with immunosuppressive therapy at or prior to enrollment (79.5% vs. 54.0%, P < 0.001). Conclusion: This report highlights clinical differences between IgAV and IgAN and between children and adults with these diagnoses. We identified differences in treatment with immunosuppressive therapies by disease type. This description of baseline characteristics will serve as a foundation for future CureGN studies.Item Fluid Accumulation After Neonatal Congenital Cardiac Surgery; Clinical Implications and Outcomes(Elsevier, 2022) Bailly, David K.; Alten, Jeffrey A.; Gist, Katja M.; Mah, Kenneth E.; Kwiatkowski, David M.; Valentine, Kevin M.; Diddle, J. Wesley; Tadphale, Sachin; Clarke, Shanelle; Selewski, David T.; Banerjee, Mousumi; Reichle, Garrett; Lin, Paul; Gaies, Michael; Blinder, Joshua J.; Pediatrics, School of MedicineBACKGROUND To determine the association between fluid balance metrics and mortality and other postoperative outcomes after neonatal cardiac surgery in a contemporary multi-center cohort. METHODS Observational cohort study across 22 hospitals in neonates (≤30 days) undergoing cardiac surgery. We explored overall % fluid overload, postoperative day 1 % fluid overload, peak % fluid overload, and time to first negative daily fluid balance. The primary outcome was in-hospital mortality. Secondary outcomes included postoperative duration of mechanical ventilation, and intensive care unit (ICU) and hospital length of stay. Multivariable logistic or negative binomial regression was used to determine independent associations between fluid overload variables and each outcome. RESULTS The cohort included 2223 patients. In-hospital mortality was 3.9% (n=87). Overall median peak % fluid overload was 4.9%, (interquartile range 0.4-10.5%). Peak % fluid overload and postoperative day 1 % fluid overload were not associated with primary or secondary outcomes. Hospital resource utilization increased on each successive day of not achieving a first negative daily fluid balance and was characterized by longer duration of mechanical ventilation (incidence rate ratio 1.11, 95% confidence interval 1.08-1.14, ICU length of stay (incidence rate ratio 1.08, 95% confidence interval 1.03-1.12), and hospital length of stay (incidence rate ratio 1.09, 95% confidence interval 1.05-1.13). CONCLUSIONS Time to first negative daily fluid balance, but not % fluid overload is associated with improved postoperative outcomes in neonates after cardiac surgery. Specific treatments to achieve an early negative fluid balance may decrease postoperative care durations.Item Pediatric AKI in the real world: changing outcomes through education and advocacy-a report from the 26th Acute Disease Quality Initiative (ADQI) consensus conference(Springer, 2024) Mottes, Theresa; Menon, Shina; Conroy, Andrea; Jetton, Jennifer; Dolan, Kristin; Arikan, Ayse Akcan; Basu, Rajit K.; Goldstein, Stuart L.; Symons, Jordan M.; Alobaid, Rashid; Askenazi, David J.; Bagshaw, Sean M.; Barhight, Matthew; Barreto, Erin; Bayrakci, Benan; Bignall, O. N., II; Bjornstad, Erica; Brophy, Patrick; Charlton, Jennifer; Chanchlani, Rahul; Conroy, Andrea L.; Deep, Akash; Devarajan, Prasad; Fuhrman, Dana; Gist, Katja M.; Gorga, Stephen M.; Greenberg, Jason H.; Hasson, Denise; Heydari, Emma; Iyengar, Arpana; Krawczeski, Catherine; Meigs, Leslie; Morgan, Catherine; Morgan, Jolyn; Neumayr, Tara; Ricci, Zaccaria; Selewski, David T.; Soranno, Danielle; Stanski, Natalja; Starr, Michelle; Sutherland, Scott M.; Symons, Jordan; Tavares, Marcelo; Vega, Molly; Zappitelli, Michael; Ronco, Claudio; Mehta, Ravindra L.; Kellum, John; Ostermann, Marlies; ADQI 26 workgroup; Pediatrics, School of MedicineBackground: Acute kidney injury (AKI) is independently associated with increased morbidity and mortality across the life course, yet care for AKI remains mostly supportive. Raising awareness of this life-threatening clinical syndrome through education and advocacy efforts is the key to improving patient outcomes. Here, we describe the unique roles education and advocacy play in the care of children with AKI, discuss the importance of customizing educational outreach efforts to individual groups and contexts, and highlight the opportunities created through innovations and partnerships to optimize lifelong health outcomes. Methods: During the 26th Acute Disease Quality Initiative (ADQI) consensus conference, a multidisciplinary group of experts discussed the evidence and used a modified Delphi process to achieve consensus on recommendations on AKI research, education, practice, and advocacy in children. Results: The consensus statements developed in response to three critical questions about the role of education and advocacy in pediatric AKI care are presented here along with a summary of available evidence and recommendations for both clinical care and research. Conclusions: These consensus statements emphasize that high-quality care for patients with AKI begins in the community with education and awareness campaigns to identify those at risk for AKI. Education is the key across all healthcare and non-healthcare settings to enhance early diagnosis and develop mitigation strategies, thereby improving outcomes for children with AKI. Strong advocacy efforts are essential for implementing these programs and building critical collaborations across all stakeholders and settings.Item Pediatric Organ Dysfunction Information Update Mandate (PODIUM) Contemporary Organ Dysfunction Criteria: Executive Summary(American Academy of Pediatrics, 2022) Bembea, Melania M.; Agus, Michael; Akcan-Arikan, Ayse; Alexander, Peta; Basu, Rajit; Bennett, Tellen D.; Bohn, Desmond; Brandão, Leonardo R.; Brown, Ann-Marie; Carcillo, Joseph A.; Checchia, Paul; Cholette, Jill; Cheifetz, Ira M.; Cornell, Timothy; Doctor, Allan; Eckerle, Michelle; Erickson, Simon; Farris, Reid W.D.; Faustino, E. Vincent S.; Fitzgerald, Julie C.; Fuhrman, Dana Y.; Giuliano, John S.; Guilliams, Kristin; Gaies, Michael; Gorga, Stephen M.; Hall, Mark; Hanson, Sheila J.; Hartman, Mary; Hassinger, Amanda B.; Irving, Sharon Y.; Jeffries, Howard; Jouvet, Philippe; Kannan, Sujatha; Karam, Oliver; Khemani, Robinder G.; Kissoon, Niranjan; Lacroix, Jacques; Laussen, Peter; Leclerc, Francis; Lee, Jan Hau; Leteurtre, Stephane; Lobner, Katie; McKiernan, Patrick J.; Menon, Kusum; Monagle, Paul; Muszynski, Jennifer A.; Odetola, Folafoluwa; Parker, Robert; Pathan, Nazima; Pierce, Richard W.; Pineda, Jose; Prince, Jose M.; Robinson, Karen A.; Rowan, Courtney M.; Ryerson, Lindsay M.; Sanchez-Pinto, L. Nelson; Schlapbach, Luregn J.; Selewski, David T.; Shekerdemian, Lara S.; Simon, Dennis; Smith, Lincoln S.; Squires, James E.; Squires, Robert H.; Sutherland, Scott M.; Ouellette, Yves; Spaeder, Michael C.; Srinivasan, Vijay; Steiner, Marie E.; Tasker, Robert C.; Thiagarajan, Ravi; Thomas, Neal; Tissieres, Pierre; Traube, Chani; Tucci, Marisa; Typpo, Katri V.; Wainwright, Mark S.; Ward, Shan L.; Watson, R. Scott; Weiss, Scott; Whitney, Jane; Willson, Doug; Wynn, James L.; Yehya, Nadir; Zimmerman, Jerry J.; Pediatrics, School of MedicinePrior criteria for organ dysfunction in critically ill children were based mainly on expert opinion. We convened the Pediatric Organ Dysfunction Information Update Mandate (PODIUM) expert panel to summarize data characterizing single and multiple organ dysfunction and to derive contemporary criteria for pediatric organ dysfunction. The panel was composed of 88 members representing 47 institutions and 7 countries. We conducted systematic reviews of the literature to derive evidence-based criteria for single organ dysfunction for neurologic, cardiovascular, respiratory, gastrointestinal, acute liver, renal, hematologic, coagulation, endocrine, endothelial, and immune system dysfunction. We searched PubMed and Embase from January 1992 to January 2020. Study identification was accomplished using a combination of medical subject headings terms and keywords related to concepts of pediatric organ dysfunction. Electronic searches were performed by medical librarians. Studies were eligible for inclusion if the authors reported original data collected in critically ill children; evaluated performance characteristics of scoring tools or clinical assessments for organ dysfunction; and assessed a patient-centered, clinically meaningful outcome. Data were abstracted from each included study into an electronic data extraction form. Risk of bias was assessed using the Quality in Prognosis Studies tool. Consensus was achieved for a final set of 43 criteria for pediatric organ dysfunction through iterative voting and discussion. Although the PODIUM criteria for organ dysfunction were limited by available evidence and will require validation, they provide a contemporary foundation for researchers to identify and study single and multiple organ dysfunction in critically ill children.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.Item Racial-Ethnic Differences in Health-Related Quality of Life among Adults and Children with Glomerular Disease(Karger, 2021) Krissberg, Jill R.; Helmuth, Margaret E.; Almaani, Salem; Cai, Yi; Cattran, Daniel; Chatterjee, Debanjana; Gbadegesin, Rasheed A.; Gibson, Keisha L.; Glenn, Dorey A.; Greenbaum, Laurence A.; Iragorri, Sandra; Jain, Koyal; Khalid, Myda; Kidd, Jason M.; Kopp, Jeffrey B.; Lafayette, Richard; Nestor, Jordan G.; Parekh, Rulan S.; Reidy, Kimberly J.; Selewski, David T.; Sperati, C. John; Tuttle, Katherine R.; Twombley, Katherine; Vasylyeva, Tetyana L.; Weaver, Donald Jack; Wenderfer, Scott E.; O’Shaughnessy, Michelle M.; Pediatrics, School of MedicineIntroduction: Disparities in health-related quality of life (HRQOL) have been inadequately studied in patients with glomerular disease. The aim of this study was to identify relationships between race/ethnicity, socioeconomic status, disease severity, and HRQOL in an ethnically and racially diverse cohort of patients with glomerular disease. Methods: Cure Glomerulonephropathy (CureGN) is a multinational cohort study of patients with biopsy-proven glomerular disease. Associations between race/ethnicity and HRQOL were determined by the following: 1. Missed school or work due to kidney disease; 2. Responses to Patient Reported Outcomes Measurement Information System (PROMIS) questionnaires. We adjusted for demographics, socioeconomic status, and disease characteristics using multivariable logistic and linear regression. Results: Black and Hispanic participants had worse socioeconomic status and more severe glomerular disease than White or Asian participants. Black adults missed work or school most frequently due to kidney disease (30% versus 16-23% in the other three groups, p=0.04), and had the worst self-reported global physical health (median score 44.1 versus 48.0-48.2, p<0.001) and fatigue (53.8 versus 48.5-51.1, p=0.002), compared to other racial/ethnic groups. However, these findings were not statistically significant with adjustment for socioeconomic status and disease severity, both of which were strongly associated with HRQOL in adults. Among children, disease severity but not race/ethnicity or socioeconomic status were associated with HRQOL. Conclusions: Among patients with glomerular disease enrolled in CureGN, the worse HRQOL reported by Black adults was attributable to lower socioeconomic status and more severe glomerular disease. No racial/ethnic differences in HRQOL were observed in children.Item Treatment Patterns Among Adults and Children With Membranous Nephropathy in the Cure Glomerulonephropathy Network (CureGN)(Elsevier, 2019-12) O’Shaughnessy, Michelle M.; Troost, Jonathan P.; Bomback, Andrew S.; Hladunewich, Michelle A.; Ashoor, Isa F.; Gibson, Keisha L.; Matar, Raed Bou; Selewski, David T.; Srivastava, Tarak; Rheault, Michelle N.; Al-Uzri, Amira; Kogon, Amy J.; Khalid, Myda; Vento, Suzanne; Sanghani, Neil S.; Gillespie, Brenda W.; Gipson, Debbie S.; Wang, Chia-shi; Parsa, Afshin; Guay-Woodford, Lisa; Laurin, Louis-Philippe; Pediatrics, School of MedicineIntroduction The 2012 Kidney Disease: Improving Global Outcomes (KDIGO) Clinical Practice Guidelines for Glomerulonephritis recommend that patients with membranous nephropathy (MN) at risk for progression receive immunosuppressive therapy (IST), usually after 6 months of observation. A cyclophosphamide (CYC) or calcineurin inhibitor (CNI)–based regimen is recommended as first-line IST. However, the extent to which KDIGO recommendations are adopted in practice remains largely unknown. Methods We evaluated prescribing practice among patients with primary MN (diagnosed 2010–2018) enrolled in the Cure Glomerulonephropathy Network (CureGN) cohort study. We also evaluated the availability of testing for phospholipase A2 receptor (PLA2R) in the contemporary era. Results Among 361 patients (324 adults and 37 children) with MN who were IST-naïve at biopsy and had at least 6 months of follow-up, 55% of adults and 58% of children initiated IST <6 months after biopsy. Of these, 1 in 5 had no indication for (i.e., urine protein-to-creatinine ratio [uPCR] <4 g/g) or an apparent contraindication to (i.e., an estimated glomerular filtration rate [eGFR] <30 ml/min per 1.73 m2) IST. As first-line IST, half of treated patients received either CYC (16% of adults; 0% of children) or a CNI (40% and 46%, respectively), whereas 1 in 5 received corticosteroid monotherapy (20% and 27%, respectively) and 1 in 6 rituximab (15% and 15%, respectively). More than 80% of surveyed centers had access to PLA2R testing. Conclusion These findings suggest that providers are not aware of, or lack confidence in, current KDIGO guidelines for MN. Treatment patterns observed in this cohort might critically inform the drafting of planned updates to KDIGO guidelines.
