The role of patients' metabolic clinical and biochemical profile in NAFLD has not been extensively explored.The aim of the study was to assess the role of metabolic health in NAFLD patients and to examine liver disease progression in these populations.The medical charts of 569 patients diagnosed with fatty liver were thoroughly reviewed; 344 patients were excluded because of other chronic liver diseases. Metabolically healthy people were defined as those who met none of the following criteria: blood pressure ≥ 130/85 mmHg or under hypertension treatment, fasting glucose ≥ 100 mg/dl or under diabetes treatment, serum triglycerides150 mg/dl, high density lipoprotein-cholesterol40/50 mg/dl for men/women. Study participants were followed-up over a median period of 22 months.The present observational case-control study included 225 NAFLD patients; 14 (6.2%) were metabolically healthy. Metabolically healthy participants were younger (p = 0.006), had lower age at diagnosis (p = 0.002), lower levels of γ-GT (p = 0.013), fasting glucose (p 0.001) and triglycerides (p 0.001) and higher HDL-cholesterol (p = 0.005) compared to metabolically non-healthy. By the last follow up assessment, 8 metabolically healthy patients had developed dyslipidemia; 1 patient (14.4%) had presented liver disease progression compared to 8 patients (10.5%) from the unhealthy group (p = 0.567). In multivariate analysis, diabetes mellitus (p = 0.017) and hemoglobin levels (p = 0.009) were the sole independent predictors of disease progression. No significant difference was observed in liver disease progression-free survival rates among the two patient groups (p = 0.503).Metabolically healthy NAFLD patients presented with a favorable biochemical profile; however, they were diagnosed with NAFLD at a younger age and the liver disease progression risk was similar to that of metabolically unhealthy patients. These findings suggest that metabolically healthy NAFLD may not constitute a benign condition and patients could potentially be at increased risk of metabolic syndrome and liver disease progression.

Objective To study the clinical and laboratory characteristics of patients with severe sepsis and baseline hyperglycemia and investigate the impact of hyperglycemia on the final outcome. Patients A total of 265 patients admitted with severe sepsis in 3 major hospitals in South-Western Greece, during a 1-year period, were included in the study. Patients were divided in 3 groups according to their glycemic profile at admission: patients with stress hyperglycemia (group SH, n = 47), with diabetes mellitus (group DM, n = 65), and with normal glucose level (group NG, n = 153). Hyperglycemia was defined as an admission or in-hospital fasting glucose level of ≥126 mg/dL or a random blood glucose level of ≥200 mg/dL on ≥2 determinations. Results A total of 42.2% of patients with severe sepsis had baseline hyperglycemia with 17.7% having sepsis-induced stress hyperglycemia. No family history was noted in the SH group. A higher percentage of septic patients with stress hyperglycemia died compared with patients with normal glucose levels (42.5% versus 13.7%) and diabetics (42.5% versus 24.6%). Group DM had also a poorer prognosis than group NG (24.6% versus 13.7%). A positive correlation was detected between the fasting blood glucose levels of group SH and the severity of sepsis indicated by sepsis-related organ failure assessment score. Conclusion Baseline hyperglycemia, including stress-induced hyperglycemia, is common in patients with severe sepsis. Stress-induced hyperglycemia is related to a more severe disease and poorer prognosis.
