The Influence and Role of Microbial Factors in Autoimmune Kidney Diseases: A Systematic Review

Table 1

Study characteristics of relevant studies in ANCA-associated vasculitis are shown. Most reports investigated the role of Staphylococcus aureus in GPA, but more recently a role of molecular mimicry with Gram negative bacteria was proposed as investigated by Kain et al. as well as by Peschel et al. [19, 20, 23] and Roth et al. [21].
