Abstract：
:Alpha 2-macroglobulin (alpha 2 M) in vitro inhibits numerous proteinases that are generated during inflammatory reactions and therefore, probably plays an important role in diseases such as sepsis. To monitor the state of alpha 2 M in sepsis, we developed novel assays for functional and inactive alpha 2M. Functional alpha 2M in plasma was measured by quantitating the binding of alpha 2M to solid-phase trypsin. Inactive alpha 2M (i alpha 2M) was assessed with a monoclonal antibody, mcAb M1, that specifically reacts with a neodeterminant exposed on i alpha 2M. This mcAb in combination with chromogenic substrates was used to detect alpha 2M-proteinase complexes. Functional alpha 2M was reduced in plasma from 48 patients with clinical sepsis compared to healthy controls (p less than 0.0001). Levels of functional alpha 2M on admission and the lowest levels encountered in 23 patients with shock were lower than in 25 normotensive patients (p = 0.023 and p = 0.009, respectively). Increased levels of i alpha 2M (greater than 30 nM) at least on one occasion were found in only 4 of the 48 patients, being not different in hypotensive compared with normotensive patients, and not in patients who died compared with those who survived. Levels of functional alpha 2M correlated significantly with levels of factor XII and prekallikrein suggesting that decreases in alpha 2M at least in part were due to contact activation. Indeed, in two patients with increased i alpha 2M, complexes between alpha 2M and kallikrein were demonstrated in addition to plasmin- and thrombin-alpha 2M complexes.
