Impact of CVVH on monocyte activation in the critically ill
Critical Care volume 4, Article number: P37 (2000)
Monocyte activation (HLA-DR+ CD14+) was suggested to be a useful marker of immune system function. As extracorporeal circuit might influence the immune response (e.g. bioincompatibility and/or elimination of pro/anti-inflammatory cytokines) we investigated the impact of CVVH initiation on monocyte activation in critically ill patients.
Fifteen septic (4 ICU survivors) and 7 nonseptic (1 ICU survivor) critically ill patients in whom CVVH (ultra-filtration 1–2 l h-1) was initiated because of acute renal failure as a part of MODS. Expression of HLA-DR+ CD14+ was assessed by flow-cytometry before CVVH initiation and at 4 h and 24 h afterwards. The Friedmann two-way ANOVA and Mann-Whitney U tests were used when appropriate. Data are presented as means ± SD; P<0.05 was considered significant.
Baseline HLA-DR+CD14+ values in septic and non-septic patients were not different (57± 21% and 71± 21% respectively, P=0.23). Time course of HLA-DR+CD14+ during the first 24h of CVVH are shown in Fig. 1.
CVVH initiation has no impact on monocyte HLA-DR expression in both septic and nonseptic patients.
