Healing of fractures of long bones or large joints is often accelerated in patients with severe traumatic brain injury (TBI). However, in these patients an early fracture healing is accompanied by hypertrophic callus formation or heterotopic ossifications which might even result in an ankylosis of the affected joints. It seems that enhanced osteogenesis in patients suffering from TBI could be caused by some humoral factors, since the sera of these patients strongly promote the growth of osteoblast cells in vitro. However, humoral growth promoting factors which could perhaps induce enhanced osteogenesis are not yet identified. Hence, the aim of this study was to analyse if basic fibroblast growth factor (bFGF) could be related to the phenomenon of enhanced osteogenesis, since bFGF stimulates the growth of osteoblasts in vitro and could be found both in the brain and the bone tissue. For that purpose the values of bFGF immunoreactivity were determined in the sera of patients with TBI and bone fractures (n = 8) as well as in the sera of patients with either TBI alone (n = 10) or bone fractures alone (n = 7), during a period of three months after injury. Quantification of the bFGF immunoreactivity was done using the ELISA based on monoclonal antibodies raised against the recombinant human bFGF. The bFGF immunoreactivity values obtained were also compared with the values determined in the sera of normal, healthy persons (n = 9). In the group of patients with bone fractures alone only a transient increase of bFGF immunoreactivity (threefold above the normal values) was observed in the second week after injury. A similar increase of the values of bFGF immunoreactivity was also determined in the sera of patients with TBI only, but it lasted longer (from the 1st until the 7th to 8th week after injury). In the case of patients with TBI and bone fractures a specific pattern of post-traumatic dynamic change of the values of serum bFGF immunoreactivity was observed. Namely, the increase of bFGF immunoreactivity (up to seven-fold above the normal values) was determined even during the first week after injury. Afterwards, periods of high values of bFGF immunoreactivity observed during the 2nd, 4th and the 7-10th weeks after injury were interrupted by sudden decreases even to the normal values (during the 3rd and the 5-6th week after injury).(ABSTRACT TRUNCATED AT 400 WORDS)
