Plasma Midkine Is Associated With 28-Day Mortality and Organ Function in Sepsis.

Abstract

BACKGROUND:

Midkine has been reported to play a crucial role in inflammatory, hypoxia, and tissue injury processes. We aimed to investigate plasma midkine in septic patients and its association with 28-day mortality and organ function.

METHODS:

Septic patients admitted to the Department of Critical Care Medicine, Zhongda Hospital, a tertiary hospital, from November 2017 to March 2018 were enrolled in the study. The baseline characteristics of the septic patients were recorded at admission. A peripheral blood sample was obtained at admission, and plasma midkine levels were evaluated with an immunoassay. All patients were followed up with for 28 days, with all-cause mortality being recorded.

RESULTS:

A total of 26 septic patients were enrolled, which included 18 survivors and 8 nonsurvivors at day 28. Plasma midkine levels were significantly elevated in the nonsurvivor group compared with the survivors (ng/L, 763.6 [404.7-1305], 268.5 [147.8-511.4]; P = .0387]. Plasma midkine levels were elevated in septic patients with moderate/severe acute respiratory distress syndrome (ARDS) compared with patients with non/mild ARDS (ng/L, 522.3 [336.6-960.1] vs 243.8 [110.3-478.9]; P = .0135) and in those with acute kidney injury compared with those without (ng/L, 489.8 [259.2-1058] vs 427.9 [129.6-510.3]; P = .0973). Changes in plasma midkine levels were also associated with extravascular lung water index (P = .063) and pulmonary vascular permeability index (P = .049).

CONCLUSIONS:

Plasma midkine was associated with 28-day mortality, as well as pulmonary and kidney injury, in septic patients.
