Bacterial infections are common complications in decompensated cirrhosis, b
ut their relationship with hemostasis has not been studied. We prospectivel
y assessed whether infection affects hemostasis in cirrhosis using routine
hemostasis tests and thrombelastography (TEG), a global test of hemostatic
function. Eighty-four cirrhotic patients (Child-Pugh B: 26; C: 58) without
overt bleeding or blood-product transfusion were prospectively evaluated wi
th routine hemostasis tests and TEG on admission and/or the first day with
signs of infection and 5 days later. There were 30 patients with infection;
15 had infection on admission, and 15 developed infection in hospital. In
the patients who developed infection in hospital, there was a significant d
eterioration in all routine hemostasis tests except platelet count (PLT) an
d in all TEG parameters, on the first day of infection compared with 7 +/-
3 days previously. The same parameters significantly improved from the firs
t day of infection to day 5 and after (P <.02) only in the 22 patients whos
e infection resolved, while the r, k, and alpha TEG parameters significantl
y worsened in the 8 patients with persistent infection. In those who develo
ped infection in hospital and were cured (n = 11), the 5-day parameters did
not differ from their preinfection values. In conclusion, bacterial infect
ions frequently impair hemostasis in decompensated cirrhotic patients. Succ
essful treatment of infection usually restores hemostasis parameters to pre
infection levels in 5 days. Thus, infection may have a role in the bleeding
diathesis of cirrhosis.
