Abstract
Introduction Critically ill children with acute kidney injury (AKI) requiring continuous kidney replacement therapy (CKRT) are at increased risk of death. The selective cytopheretic device (SCD) promotes an immunomodulatory effect when circuit ionized calcium (iCa2+) is maintained at <0.40 mmol/l with regional citrate anticoagulation (RCA). In a randomized trial of adult patients on CRRT, those treated with the SCD maintaining an iCa2+ <0.40 mmol/l had improved survival/dialysis independence. We conducted a US Food and Drug Administration (FDA)–sponsored study to evaluate safety and feasibility of the SCD in 16 critically ill children. Methods Four pediatric intensive care units (ICUs) enrolled children with AKI and multiorgan dysfunction receiving CKRT to receive the SCD integrated post-CKRT membrane. RCA was used to achieve a circuit iCa2+ level <0.40 mmol/l. Subjects received SCD treatment for 7 days or CKRT discontinuation, whichever came first. Results The FDA target enrollment of 16 subjects completed the study from December 2016 to February 2020. Mean age was 12.3 ± 5.1 years, weight was 53.8 ± 28.9 kg, and median Pediatric Risk of Mortality II was 7 (range 2–19). Circuit iCa2+ levels were maintained at <0.40 mmol/l for 90.2% of the SCD therapy time. Median SCD duration was 6 days. Fifteen subjects survived SCD therapy; 12 survived to ICU discharge. All ICU survivors were dialysis independent at 60 days. No SCD-related adverse events (AEs) were reported. Conclusion Our data demonstrate that SCD therapy is feasible and safe in children who require CKRT. Although we cannot make efficacy claims, the 75% survival rate and 100% renal recovery rate observed suggest a possible favorable benefit-to-risk ratio.

Abstract
OBJECTIVE To assess composite health outcomes in pediatric and young adult kidney transplant recipients following kidney transplantation. STUDY DESIGN We conducted a cross-sectional study of all recipients at our center who had a 1-, 3-, 5-, and/or 10-year transplant anniversary visit between October 2008 and February 2015. The kidney transplant recipients were assessed at each time point according to an outcome measure consisting of 15 pass/fail criteria in 5 domains: allograft health, rejection and immunology, infection, cardiovascular health, and growth. RESULTS We analyzed 148 patients at 231 transplantation anniversary visit time points; 52 of 82 (63%) patients assessed at 1 year had an ideal outcome, meeting at least 13 of the 15 criteria. This decreased to 37% at year 3, 40% at year 5, and 26% at year 10 (P < .01). The most common failures across all time points occurred in the domains of growth (43%-52% passing) and cardiovascular health (33%-51% passing). Allograft health declined significantly, decreasing from 74% at year 1 to 33% at year 10 (P < .01). The percentage of patients with graft failure increased from 2.4% at 1 year to 39.5% at 10 years (P < .01), and patient deaths increased from 0 to 11% (P < .01) in the same time frame. CONCLUSIONS Ideal outcomes for pediatric kidney transplant recipients decrease over time with growth, cardiovascular health, and allograft health as the primary failure modes. Understanding the composite health of young recipients will allow primary care providers and nephrologists alike to evaluate the overall health of kidney transplant recipients and focus clinical care on the most common sequelae.

Abstract
MMF is commonly prescribed following kidney transplantation, yet its use is complicated by leukopenia. Understanding the genetics mediating this risk will help clinicians administer MMF safely. We evaluated 284 patients under 21 years of age for incidence and time course of MMF-related leukopenia and performed a candidate gene association study comparing the frequency of 26 SNPs between cases with MMF-related leukopenia and controls. We matched cases by induction, steroid duration, race, center, and age. We also evaluated the impact of induction and SNPs on time to leukopenia in all cases. Sixty-eight (24%) patients had MMF-related leukopenia, of which 59 consented for genotyping and 38 were matched with controls. Among matched pairs, no SNPs were associated with leukopenia. With non-depleting induction, UGT2B7-900A>G (rs7438135) was associated with increased risk of MMF-related leukopenia (P = .038). Time to leukopenia did not differ between patients by induction agent, but 2 SNPs (rs2228075, rs2278294) in IMPDH1 were associated with increased time to leukopenia. MMF-related leukopenia is common after transplantation. UGT2B7 may influence leukopenia risk especially in patients without lymphocyte-depleting induction. IMPDH1 may influence time course of leukopenia after transplant.

Abstract
OBJECTIVE To develop and evaluate a system for reliable and efficient individualized risk-based monitoring of cholesterol and 11 other tests after kidney transplantation in children. METHODS We identified system components that drive reliable individualized monitoring and used quality improvement methods to develop and implement interventions, including (1) monitoring schedules individualized by dyslipidemia risk assigned to each patient, (2) automated previsit decision support from our electronic medical record, (3) standardized work flow and responsibility, and (4) automated forwarding of results to providers. We measured the proportion of patients due for cholesterol testing who had it performed within 1 week of their clinic visit and the proportion of patients in our population who achieved low-density lipoprotein (LDL) cholesterol control at baseline and for 2 years after improved monitoring. RESULTS The proportion of visits in which cholesterol monitoring was completed when indicated improved from 80% to 98% within 8 months and was sustained for more than 1 year. The number of patients with controlled LDL (<130 mg/dL, 3.3 mmol/L) improved from 44 (71%) of 62 at the start of our project to 58 (94%) of 62 (P = .002) at an average follow-up of 24 months. CONCLUSIONS Using quality improvement and health information technology, we achieved sustained, reliable and efficient personalized monitoring of cholesterol and 11 other tests. This approach enabled substantial improvement in LDL cholesterol control. Structured methods of system redesign that leverage information technology systems hold promise for rapidly achieving reliable individualized care in other settings.

Abstract
BACKGROUND Pediatric eosinophilic esophagitis (EE) is a recently described disorder associated with atopy. Although studies of esophageal tissue suggest that Th2 cytokines and eotaxin-3 may be crucial in disease pathogenesis, little is known about the systemic immunological phenotypes of children with EE. OBJECTIVES To define the phenotypes of peripheral blood eosinophils and lymphocytes in EE and to examine for correlations between these parameters and tissue eosinophil numbers and disease severity. PATIENTS AND METHODS Blood was collected from children with EE, atopic control children without EE, and nonatopic control children without EE. Flow cytometry was used to measure eosinophil expression of chemokine receptor 3 (CCR3) and interleukin-5 receptor-alpha (IL-5Ralpha), and intracellular lymphocyte expression of IL-4, IL-5, IL-13, interferon-gamma, and tumor necrosis factor-alpha. Eosinophil numbers and eotaxin-3 mRNA levels were quantitated in esophageal biopsy specimens. RESULTS Compared with nonatopic control children, EE patients with active disease had increased peripheral blood eosinophil percentages, mean channel of fluorescence (MCF) of CCR3 on eosinophils, and percentage of CD4+ T cells expressing IL-5. Notably, these parameters positively correlated with esophageal eosinophil numbers. Eotaxin-3 tissue expression positively correlated with esophageal eosinophil numbers and peripheral blood eosinophil CCR3 MCF. The percentage of peripheral blood eosinophils, eosinophil CCR3 MCF, and CD4+ T cell expression of IL-5 were lower in EE patients in disease remission than in patients with active disease. CONCLUSIONS Collectively, these studies demonstrate cooperation between systemic CD4+ Th2-cell-mediated immunity and an enhanced eosinophil-CCR3/eotaxin-3 pathway in EE pathogenesis. Furthermore, the imbalanced Th2 immunity and increased CCR3 expression are reversible with disease remission.

Abstract
BACKGROUND Eosinophilic esophagitis (EE) is a gastrointestinal disorder that is increasingly diagnosed in pediatric patients. OBJECTIVE We aimed to define, in pediatric patients with EE, their demographic and atopic characteristics, the histopathology of all segments of the gastrointestinal tract, and the effect of therapeutic interventions on the natural history. METHODS We conducted a retrospective analysis of a database of pediatric patients with EE followed over a period of 8 years. RESULTS In 89 pediatric patients with EE, male sex (78.6%), white race (94.4%), young age at diagnosis, mean +/- SD, 6.2 +/- 4.8 years, and atopy with sensitization to environmental and food allergens in 79% and 75%, respectively, were prevalent. Patients had EE of the proximal and distal esophagus, and 77% had in addition either mucosal eosinophilia or noneosinophilic histopathology in the stomach, duodenum, and colon. EE was chronic, with a duration of mean +/- SD, 0.91 +/- 0.84 years, until first resolution, and was recurrent; of 66% of the patients who had resolution, 79% later relapsed. CONCLUSION Eosinophilic esophagitis in the pediatric population is a chronic and relapsing condition, associated with atopy and sometimes with subsequent histopathology in segments of the gastrointestinal tract other than the esophagus. CLINICAL IMPLICATIONS Physicians evaluating pediatric patients with chronic gastrointestinal symptoms should consider the diagnosis of EE, particularly in young white male patients with atopy. Once diagnosed and treated, the physicians should follow the patients over a period of several years because the course of the disease is protracted, other gastrointestinal segments may be affected, and relapses are common.

Abstract
PURPOSE To determine if the size of the extrahepatic bile duct increases with age in adults. MATERIALS AND METHODS A total of 258 consecutive patients 18 years and older, without known biliary or pancreatic disease, who were fasting to undergo routine abdominal sonography were examined. The transverse and anteroposterior dimensions of the extrahepatic bile duct were measured proximally at the porta hepatis, at the middle above the head of the pancreas, and distally at the head of the pancreas. Simple linear regression of the average of these measurements against age tested the hypothesis of a slope of 1.0 mm per decade. RESULTS The sample included a wide variety of ages: 55 years +/- 16 (mean +/- SD), with a range of 20-92 years, including 151 men and 107 women. One-tenth of the cohort were younger than 35 years old and one-tenth were older than 77 years old. The six measurements were proximal-transverse 3.5 mm +/- 1.0, proximal-anteroposterior 2.9 mm +/- 1.1, middle-transverse 3.9 mm +/- 1.2, middle-anteroposterior 3.4 mm +/- 1.2, distal-transverse 4.1 mm +/- 1.2, distal-anteroposterior 3.5 mm +/- 1.2. Least squares regression slope differed significantly from 0.1 mm per year (95% CI; -0.000703, +0.00110) and in fact contained zero. CONCLUSION Findings were not able to help confirm an association between age and size of the extrahepatic bile duct in an asymptomatic adult population.

Abstract
We set out to evaluate the accuracy of nonenhanced helical computed tomography (CT) scanning at stone detection in the patient with acute flank pain, and as a means of detecting noncalculus causes of acute flank pain. Between April 1995 and April 1997, 412 consecutive patients with acute flank pain underwent noncontrast-enhanced helical CT. Two hundred eighty-one patients had confirmation of their CT diagnosis by other radiographic studies, urologic intervention, or spontaneous stone passage of calculi. We determined the presence or absence of urinary calculi, as well as the presence of other noncalculus pathology. CT scanning revealed a stone in 92/281 patients (32.7%) and no stone in 189/281 patients (67.3%). Of the 189 patients, 60/189 patients (32%) had another positive finding as a cause for flank pain. Eighty-one of 92 patients with a stone on CT (88%) had confirmation of stone disease by radiologic or surgical intervention. Eleven of 92 patients (12%) did not have confirmation of their diagnosis because of resolution of symptoms or refusal of further intervention. On helical CT scans 129/189 patients demonstrated no abnormalities. Two of 189 (1.5%) thought to be stone free by CT passed a stone. Helical CT had a sensitivity of 97%, a specificity of 92%, a positive predictive value of 88%, and a negative predictive value of 98% at stone detection. Noncontrast-enhanced helical CT is accurate and rapid in detecting calculus disease in patients with acute flank pain. Perhaps more importantly, it provides the added benefit of detecting noncalculus causes of flank pain in greater than 30% of patients.

Abstract
OBJECTIVE This study compared carotid artery sonography with angiography to determine, in retrospect, which types of sonographic errors arose from incorrect interpretation of sonographic images and which errors could be ascribed to the limitations of sonographic imaging. MATERIALS AND METHODS A review of all patients who underwent carotid artery sonography and angiography between 1993 and 1997 at our institution revealed 66 patients with complete sets of studies, yielding 132 examinations (right or left). Studies were not reinterpreted and angiography was considered to be the gold standard. Only stenoses of 60% or greater were included in our study. If the degree or location of stenosis differed on the two imaging studies, they were reviewed together to classify the type of sonographic error. RESULTS We found complete agreement of sonography and angiography in 115 cases (87%) and discrepancies in 17 (13%). Thirteen of 17 sonographic errors were false-positive interpretations and three were false-negative interpretations. One was an error in location. Retrospective review showed seven interpretive errors. In all these cases, the color Doppler image better revealed the degree of stenosis. Other complicating factors included inconsistencies between absolute velocities, velocity ratios, and waveforms obtained while a patient was being treated with an intraaortic balloon pump. In the other 10 discrepancies, the sonographic interpretation was accurate. Seven of these cases were false-positive interpretations in patients with contralateral occlusions or stenoses. The other three cases in this group showed long segments of stenosis, ulcerations, or tortuous vessels on angiography. CONCLUSION Our study suggests that increased accuracy can be achieved in the interpretation of carotid artery sonography by meticulous attention to the color image. When color Doppler sonography is technically limited by tortuosity or ulceration, or if significant contralateral disease is present, misinterpretation is more likely.

Abstract
The variable sonographic appearance of duplication cysts is presented. Eighteen sonograms from 14 patients, aged 1 day to 8 years, were reviewed over an 8 year period. Water and other aqueous contrast agents were used in six patients as part of the sonographic evaluation. All lesions were confirmed by surgery. All but two patients were symptomatic. Twenty-four cysts were detected, ranging in size from 1.7 to 15.5 cm. The duplication cysts revealed a spectrum of sonographic findings (cystic to solid appearing masses). The mass characteristics, including the "muscular rim sign," and internal debris or hemorrhage, were demonstrated. Multiple unsuspected cysts (3 of 14 or 20%) and complications such as perforation were readily seen with ultrasonography. Serial sonograms demonstrated the changing morphology of two cysts. Other unsuspected intra-abdominal and pelvic pathologic conditions, including pyloric stenosis and ovarian cysts, were identified. Identification of the muscular rim sign is the most reliable indication of a duplication cyst. Multiple masses as well as possible accompanying anomalies in the abdomen and pelvis are readily evaluated with sonography. Lesions are easily followed with serial studies if there is no surgical intervention.
