“…A subsequent report from the same group revealed the presence of anti-LAMP-2 autoantibodies in patients from Austria, the Netherlands and the United Kingdom [25]. The same group later published that 8 of 11 (73%) of patients with ANCA-negative pauci-immune focal necrotizing glomerulonephritis harbored anti-LAMP-2 autoantibodies [26]. In a conflicting report, Roth et al measured anti-LAMP-2 autoantibodies in 680 serum samples from two academic centers in the United States from patients with ANCA glomerulonephritis (n = 329), ANCA-negative glomerulonephritis (n = 104), patients with E. coli urinary tract infection (UTI, n = 104), disease controls (n = 19) and healthy volunteers (n = 124) [27].…”
