Effects of methylprednisolone and dexamethasone on polymorphonuclear leukocyte adherence in vivo

It has been proposed that corticosteroids may be effective in the treatment of shock and the adult respiratory distress syndrome (ARDS) by inhibiting complement-induced granulocyte aggregation and by disaggregating granulocyte aggregates in vitro. In the present investigation we have examined the ef...

Summary:It has been proposed that corticosteroids may be effective in the treatment of shock and the adult respiratory distress syndrome (ARDS) by inhibiting complement-induced granulocyte aggregation and by disaggregating granulocyte aggregates in vitro. In the present investigation we have examined the effects of sera from patients who had received comparable doses of methylprednisolone (MP) and dexamethasone (DEX) on the adherence of polymorphonuclear leukocytes (PMNs). Sera obtained from patients that had received MP markedly reduced PMN adherence with maximum effect noted by 8 h. In contrast, sera from patients receiving DEX had no effect on PMN adherence. The results of this study indicate that MP may be more effective in the treatment of septic shock and other conditions associated with microvascular leukostasis.
