    Purpose Febrile neutropenia (FN) is a hematological emergency. It is challenging and confusing for the clinicians to make the decision of the febrile neutropenic patients under chemotherapy to be monitored at intensive care unit (ICU). The aim of this study was to define the factors supporting decision-making for the critical patients with febrile neutropenia. Methods The data of 60 patients, who were taken to the ICU while they were under treatment in the Hematology Clinic with a diagnosis of febrile neutropenia, were analyzed retrospectively, in order to identify clinically useful prognostic parameters. Results The ICU mortality rate was 80%. Mortality was significantly associated with higher sequential organ failure assessment score (SOFA), quick sequential organ failure assessment score (qSOFA), and hematological SOFA (SOFAhem) scores on admission. All cases having SOFA score 10 and above and qSOFA score 2 and above died. In multivariate analysis, qSOFA score was found to be statistically significant in predicting mortality in regard to ICU admission (p = 0.004). Conclusion Mortality of febrile neutropenic patients admitted to ICU is high. It would be appropriate to determine the extent of organ dysfunction instead of underlying disease, for making the decision of ICU admission. It should be noticed that the risk mortality is high for the FN cases with SOFA score 10 or above, qSOFA score 2 or above, and in need of mechanical ventilation and positive inotropic support; hence, early intervention is recommended. In our study, the most significant parameter in predicting ICU mortality was found to be qSOFA.

    Introduction: Cardiovascular disease is the main cause of mortality and morbidity in chronic renal failure. It's known that vascular calcification (VC) and carotid intima media thickness (CIMT) are strongly associated with cardiovascular diseases. Growth arrest specific protein 6 (Gas6) is a vitamin K-dependent protein and regulates various processes such as proliferation, cell survival, migration and inflammation. Gas6 is known to protect endothelial cells and vascular smooth muscle cells against apoptosis by inhibiting Bcl-2 induced Caspase 3 activation. The relationship between Gas6 and cardiovascular diseases has been demonstrated in many mouse models and cell cultures. However, there are conflicting reports whether Gas6 levels are increasing or decreasing in human studies of diabetic and/or chronic renal failure. In present study the aim was to examine plasma Gas6 levels and its relation with CIMT and coronary artery calcification score (CACS) in chronic kidney disease (CKD) patients. Methods: Total of 137 patients of which 32 chronic hemodialysis and 105 predialysis patients as well as 73 healthy controls were enrolled in the study. Human Gas6 levels in serum samples were studied by ELISA method. CIMT was measured by ultrasonography. CACS was measured by multislice computed tomography. Results: The mean age was 54.37 +/- 16.61 years in dialysis group, 55.20 +/- 14.80 years in predialysis group and 53.26 +/- 9.04 years in control group. Serum creatinine was 0.78 +/- 0.16 mg/dl in the control group and 1.96 +/- 1.64 mg/dl in the predialysis and 5.94 +/- 1.55 mg/dl in the dialysis group. 24 hours urine protein levels were significally higher in the dialysis group than the predialysis and the control group. CIMT values were similar in predialysis and dialysis groups. These values were significantly higher than control group. Although CACS was higher in dialysis group than predialysis and control group, the results were not statistically significant since the distribution range was very wide. Gas6 was 98.84 +/- 53.32 ng/mL in the control group and statistically higher than dialysis (63.85 +/- 38.92 ng/mL) and predialysis groups (54.96 +/- 38.49 ng/mL) (p=0.001). Gas6 levels were lower in diabetic patients than non-diabetics (53.69 +/- 35.26 ng/mL, 69.26 +/- 47.50 ng/mL, p=0.023, respectively). Negative correlation was detected between Gas6 and age, BMI, CACS, carotid IMT and proteinuria. In the logistic regression analysis, Gas6 remained significantly associated with BMI, CIMT and proteinuria. Conclusion: In our study, a negative correlation of Gas6 with BMI, CACS, CIMT and proteinuria and lower Gas6 levels in diabetic patients support that decreased Gas6 levels in chronic renal failure may have a role in vascular calcification through altered glucose tolerance, chronic inflammation, endothelial dysfunction and increased apoptosis. Our study has an importance because it is the first study showing a relation between Gas6 and proteinuria, CACS and carotid IMT in patients with chronic renal failure.
