TY - JOUR T1 - POlymyxin b hemoperfusion and mortality in abdominal septic shock AU - Kida Y Y1 - 2009/11/11 N1 - 10.1001/jama.2009.1608 JO - JAMA SP - 1968 EP - 1970 VL - 302 IS - 18 N2 - To the Editor: Dr Cruz and colleagues1 concluded that polymyxin B hemoperfusion added to conventional therapy reduced 28-day mortality in patients with severe sepsis or septic shock from intra-abdominal gram-negative infections. However, Table 2 in their article showed that gram-positive bacteria such as Enterococcus, Staphylococcus, and Streptococcus were more frequently isolated in the polymyxin B hemoperfusion group than the conventional therapy group. Therefore, the frequencies of gram-negative sepsis and severe endotoxemia seemed to be high in the conventional therapy group compared with the polymyxin B hemoperfusion group.
