Table 3 Sensitization against HLA antigens and anti-ABO antibodies before and after liver transplantation among pediatric patients who have received an ABO-incompatible liver transplant in Finland.
Patients with anti-HLA antibodies before LT, n (%)1 | 5 (30) |
Median number of HLA mismatches, n (range)2 | |
Class 1 | 1.5 (1–4) |
Class 2 | 1.5 (0–2) |
Positive leukocyte crossmatch before LT, n (%) | 1 (6) |
Patients with anti-ABO antibodies before LT, n (%)3 | 9 (82) |
Mean peak anti-ABO antibody titer before LT2 | |
IgG ABO antibodies | 16 (0–32) |
IgM ABO antibodies | 8 (0–32) |
Patients with anti-ABO antibodies after LT, n (%)2 | 4 (36) |
Mean peak anti-ABO antibody after LT2 | |
IgG ABO antibodies | 21 (0–256) |
IgM ABO antibodies | 19 (0–256) |
1 Data available from 15/16 patients; 2 available from 11/16 patients; 3 data available from 9/16 patients. LT – liver transplantation; HLA – human leukocyte antigen. |
