    Clinical presentation and outcome of pediatric ANCA-associated glomerulonephritis
    (Springer, 2017-03) Kouri, Anne M.; Andreoli, Sharon P.; Department of Pediatrics, IU School of Medicine
    Background Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is a small- and medium-sized vasculitis classically seen in adult patients, with peak onset near the fifth to seventh decade of life. There is little data on ANCA-associated vasculitis in pediatric patients, and most studies have limited follow-up. Methods This is a retrospective chart review of 22 patients with ANCA-positive glomerulonephritis in a single institution from 1991 to 2013. Results Of the 22 patients, eight (36 %) required renal replacement therapy (RRT) at diagnosis; four of these patients recovered sufficient renal function to initially discontinue dialysis. Five patients (23 %) were treated with plasmapheresis at presentation. The median time from presentation until first clinical or serologic relapse was 1.7 ± 1.2 years. After a median follow-up of 5.8 years, just over half of our patients had chronic kidney disease (CKD) stages 1–3 (55 %). Seven (32 %) patients progressed to end-stage renal disease (ESRD) and eventually required kidney transplant. Conclusion ANCA-associated glomerulonephritis is a rare disorder in children. Presentation and outcomes vary significantly among patients. More research is required to follow these patients who are diagnosed in childhood to further characterize the long-term outcome of the disease.

    Evaluation of T2Candida Panel for detection of Candida in peritoneal dialysates
    (Sage, 2019-01) Kouri, Anne M.; Kieffer, Theodore W.; Nailescu, Corina; Leiser, Jeffrey; Schmitt, Bryan H.; Relich, Ryan F.; Davis, Thomas E.; Manaloor, John J.; Pediatrics, School of Medicine
    Fungal peritonitis in the peritoneal dialysis population is difficult to diagnose promptly due to the inherently slow cultivation-based methods currently required for identification of peritonitis pathogens. Because of the moderate risk for severe complications, the need for rapid diagnostics is considerable. One possible solution to this unmet need is the T2Candida Panel, a new technology designed to detect the most common pathogenic Candida spp. directly from whole blood specimens in as little as a few hours. We hypothesized that this technology could be applied to the detection of Candida in peritoneal dialysate, a matrix not currently approved by the Food and Drug Administration for testing by this system. Remnant dialysate samples from three healthy (noninfected) pediatric peritoneal dialysis patients were spiked with Candida glabrata, serially diluted, and tested in triplicate with unaltered dialysate specimens. The assay detected C. glabrata in 100% of spiked dialysate samples across the full spectrum of dilutions tested, and no assay inhibition or cross-reactivity was noted. These findings suggest one of possibly more applications of this technology. The positive clinical implications of this test will continue to be realized as its use is validated in peritoneal dialysate and other patient specimen types.
