We measured the serum gelsolin, actin-modulating protein, levels in fi
ve patients after rhabdomyolysis. We observed a tendency of serum gels
olin (83 kDa) to increase during the study period of 11 days. No intra
cellular gelsolin (80 kDa) was found in the serum, although it is abun
dant in muscle, and the destruction was severe as judged by other para
meters. Serum gelsolin thus behaves differently in rhabdomyolysis than
after acute tissue damage in other organs, such as liver necrosis and
adult respiratory distress syndrome. (C) 1998 Elsevier Science B.V.
