  1. Cases 1 and 2 are from the current case report.
  2. Cases 3-5 published by Klomjit et al.
  3. Cases 6-11 published by Sethi et al.
  4. Case 8 reached IR without improved proteinuria with rituximab, as such had a normal PLA2R antibody titer at time of obinutuzumab therapy.
  5. Case 11 was serum PLA2R negative but stained positive in their renal biopsy specimen.
  6. *data obtained from the graph of the paper by Sethi et al without the raw data available.
  7. M male, F female, PCR protein creatinine ratio, PLA2R phospholipase A2 receptor, IR immunological remission, NA not available.
