Pre-transplant serum creatinine, GGT, total bilirubin, ferritin, CRP, and albumin were checked, and while most of these variables did not differ significantly regarding SOS groups (p>0.05), albumin was found to be lower in patients with SOS compared to those without SOS (p=0.02) (Table 2). This evidence concerns the gene CRP and spondylo-ocular syndrome.
