BACKGROUND: Soluble fibrinogen-like protein 2 (sfgl2), which is mainly secreted by T cells, is a novel effector of regulatory T cells with immunosuppressive functions. The aim of this study was to investigate serum levels of sfgl2 among renal allograft recipients.
METHODS: From November 2010 to August 2011 we retrospectively divided 47 renal allograft recipients into an acute rejection (n = 19) versus a stable group (n = 28) according to allograft biopsy results, using the Banff 2007 classification. The acute rejection group was subdivided into grade I (n = 8) versus grade II T-cell-mediated (n = 6) or antibody-mediated rejection episodes (n = 5). Peripheral blood samples were collected at the time of biopsy. Fourteen healthy volunteers were included as normal group controls. Serum levels of sfgl2 were analyzed by enzyme-linked immunosorbent assay.
RESULTS: Serum levels of sfgl2 were increased among renal allograft recipients suffering from biopsy-proven acute rejection episodes (61.91 ± 45.68 ng/mL), versus those with stable allografts (38.59 ± 19.92 ng/mL, P < .05) or healthy volunteers (29.10 ± 18.08 ng/mL, P < .05). The sfgl2 level was significantly higher among patients with antibody-mediated (118.48 ± 55.54 ng/mL) than T-cell-mediated acute rejection episodes (41.71 ± 16.44 ng/mL, P < .01). Serum sfgl2 levels were remarkably elevated in patients with grade II (51.87 ± 19.13 ng/mL) versus grade I T-cell-mediated rejection (34.10 ± 9.26 ng/mL, P < .05).
CONCLUSIONS: Serum sfgl2 levels were increased among renal allograft recipients with acute rejection episodes to an extent dependent upon the pathological type and severity of the response.
