Objective: Establishing a serological profile of interleukin 6 (IL-6) in order to evaluate its usefulness as a biological marker for the diagnosis and early prognosis in sepsis.
Materials and Methods: The study included 246 individuals, divided into 2 groups: 131 in the septic subgroup (S) and 115 in the septic shock (SS) subgroup. Inflammatory markers, bacteriological examinations and laboratory samples were determined within 24 hours of the first signs of infection. Severity scores were also calculated within the first day of the onset of sepsis.
Results: The SS subgroup (median 121.2 pg/ml, 18.59-10235 pg/ml; SD = 1920) shows significantly higher values of IL-6, compared to the S subgroup (median 43.49 pg/ml, 13, 27-6566 pg/ml; SD = 1367) (p = 0.0026). The SS subgroup has a significantly higher death rate than S subgroup (p = 0.001). The cut-off values of the mortality prediction degree were 184.74 pg/ml. The area under the curve of the cytokine IL-6 for the differentiation of sepsis from septic shock was 0.693 (95% CI 0.582-0.790, p = 0.002). The optimal value of the cut-off that allows the differentiation of the septic subgroup from the one with organ dysfunction, was 52.72 pg / ml.
Conclusion: Serum IL-6 values are significantly higher in the septic shock group. All deceased patients had higher IL-6 serum values.

The Relationship Between Chronic Inflammation and Glucidic-Lipidic Profile Disorders in Kidney Transplant Recipients
Introduction: Chronic inflammation has a proven role in atherogenesis, lipid profile parameters being related to cytokine production. In kidney transplant recipients, interleukin 6 (IL-6) is significantly associated with graft-related outcomes and also alterations of cholesterol and triglyceride metabolism. The aim of this study was to investigate the relationship between chronic inflammation and glucidic-lipidic metabolism disorders in a group of patients with kidney transplantation as renal replacement therapy.
Methods: A prospective observational study which enrolled thirtysix non-diabetic kidney transplant recipients was conducted in the Nephrology and Peritoneal Dialysis Department, County Clinic Hospital of Tirgu Mures. The study group was divided as following: recipients with serum IL-6 concentration higher than 3.8 pg/ml (group A) and IL-6 within the normal range (group B).
Results: Allograft recipients with higher serum IL-6 had significant higher erytrocyte sedimentation rate(ESR, p=0.0067). Patients with over-the-range levels of IL-6 had significant higher levels of serum cholesterol and LDL-cholesterol respectively (p=0.0242 and p=0.0081). Serum Apo-B was also significant higher in Group A than Group B. Protein excretion was significant higher in patients from group A (p=0.0013). No statistical significant relationship could be proven between elevated levels of IL-6 and hbA1c, insulin and glycosuria disturbances in the two groups. Also, we found no statistical significant association between resistivity and pulsatility indices (both hilum and intragraft) or carotid intima media thickness.
Conclusion: Serum interleukin 6 is related to lipid profile disorders and less to glucidic metabolism anomalies in non-diabetic kidney transplant recipients.
