    Markers of inflammation as determinants of mortality in intensive care unit patients
    (Springer, 2007) Kuvandik, Guven; Ucar, Edip; Borazan, Ali; Aydemir, Selim; Ilikhan, Sevil; Sekitmez, Nedred; Duru, Mehmet
    In this study, the investigators explored the relationship between mortality rate and serum levels of C-reactive protein (CRP), erythrocyte sedimentation ratio (ESR), albumin, and hemoglobin, leukocyte, and platelet counts of patients at the time of first admission to the intensive care unit (ICU). A total of 123 patients were admitted to 2 different ICUs. In the emergency departments, serum levels of CRP, ESR, and albumin and hematologic parameters of 81 patients who died and were 42 patients who survived were compared. Student t test and the chi(2) test were used for statistical analyses. Mean CRP and ESR levels and leukocyte counts were higher in nonsurvivor than in survivor groups (P<.001 for all). Additionally, serum CRP and ESR elevations and leukocyte counts were determined to be individually related to mortality (P<.001, P<.05, and P<.05, respectively). The investigators concluded that initial serum levels of CRP and ESR and leukocyte counts can be used as determinants of mortality in ICU patients.

    We aimed to study the relationship between the C-reactive protein (CRP), albumin, and fibrinogen as cardiovascular risk factors in continuous ambulatory peritoneal dialysis (CAPD) patients, in the early stage of their therapy. The study included 21 CAPD patients as the study group (SG) and age- and sex-matched 21 healthy patients as the control group (CG). History and physical exam data were obtained for all cases, and demographic baseline characteristics were taken. Twelve-hour fasting serum levels of glucose, total cholesterol, HDL cholesterol, LDL cholesterol, triglyceride, total protein, albumin, hemoglobin, CRP, and fibrinogen were obtained. There was no statistically significant difference between the SG and CG in baseline characteristics, including age, sex, body mass index (BMI), smoking, and family history of cardiovascular disease. However, diabetes mellitus (DM) and hypertension (HTN) were significantly more common among the study group. The average total protein, albumin, and hemoglobin levels were significantly lower, and the CRP and fibrinogen levels were significantly higher (p < 0.001) in the SG. A positive correlation was seen (r = 0.443, p < 0.05) among CRP and fibrinogen levels in SG. There was no correlation among the other parameters in SG. For CG, there was no correlation seen for any studied parameters. When patients with and without cardiovascular disease (CVD) were compared, no correlation was seen between CRP and other parameters. A positive correlation of CRP and fibrinogen levels as cardiovascular risk factors was shown in early stage of CAPD patients. The CAPD patients with elevated levels of CRP and fibrinogen should receive close follow-up for cardiovascular disease prevention.
