Adipocytokine profile seems to play a distinct role in the pathogenesis of chronic hepatitis C (CHC). Chemerin and vaspin are recently described adipocytokines with various suggested functions and potential to modulate inflammatory response and insulin resistance (IR). We assessed chemerin, vaspin and leptin serum concentration and studied their association with IR laboratory and morphological features in patients with hepatitis C. The study included 40 patients with hepatitis C and 20 healthy volunteers, similar in age and body mass index (43.6 +/- 11.6 vs 40.9 +/- 11.8 years and 25.0 +/- 4.1 vs 23.9 +/- 3.3 kg/m(2), respectively). Patients had to have a normal lipid profile, and diabetes was an exclusion criteria. Serum chemerin and leptin levels and IR were significantly higher in patients with hepatitis C when compared to the controls (P = 0.02, P = 0.02 and P = 0.02, respectively), whereas vaspin level was significantly decreased (P = 0.01). Serum chemerin was negatively associated with necro-inflammatory grade (r = (-0.49), P = 0.01). The lowest levels of serum chemerin were found in patients with moderate/severe inflammation (P = 0.03). Serum leptin tended to be up-regulated in patients with minimal inflammatory activity. Serum vaspin was higher, although not significantly, when fibrosis was more advanced. IR was positively associated with fibrosis stage (r = 0.33, P = 0.03). Serum chemerin and leptin were related to each other (r = 0.45, P = 0.02).Our findings support a complex interaction between the analysed adipokines and pathogenesis of inflammatory process in CHC. The role of chemerin and vaspin in pathogenesis of inflammatory response should be further investigated.

Aim: Screening and extended assessment of the nutritional status of patients on admission and on discharge from hospital were carried out. Description: The studies were carried out in four teaching hospitals, four provincial hospitals and four county hospitals in Poland. Subjects: Screening examinations were carried out for 3310 randomly selected patients (every 10th patient admitted to hospital, including 1916 female cases aged from 16 to 92 y and 1394 male patients aged from 16 to 100 y). Extended examinations were carried out on 210 patients aged from 16 to 87 y (including 122 female and 88 male). Main assessment parameters: Anthropometric (height, weight, body mass index (BMI), waist-to-hip ratio (WHR), arm circumference) and biochemical indices (erythrocyte count, haemoglobin concentration, white blood cell count, blood lymphocyte count and serum albumin serum concentration). The extended examinations included determination of antioxidant vitamins (A, C, E), vitamin B 12 and folic acid. Results: On admission to hospital, 10.43% of the patients surveyed had a BMI below 20 kg/m 2 , in 20.74% of patients serum albumin concentration was below 3.5 g/dl, indicating possible protein energy malnutrition. In addition, 21.02% had lymphocyte count below 1.5 Â 10 3 /mm 3 . During hospitalisation, deterioration in the nutritional status of the patient population occurred. On discharge from hospital, the percentage of patients with BMIo20 kg/m 2 increased to 11.21% and the percentage with low blood albumin (o3.5 g/dl) increased to 28.57%. On admission, vitamin C deficiency was present in 51.8% of patients, folic acid deficiency in 32%, vitamin E deficiency in 10%, vitamin B 12 deficiency in 6.8% and vitamin A deficiency in 1.4%. Vitamin deficiencies were present equally in malnourished, overweight and obese patients. Conclusions: In patients admitted to hospitals in Poland, malnutrition risk demonstrated by BMI was observed in 10.43% of patients. On the basis of biochemical indices, increased nutritional risk was demonstrated in 21% of patients. Vitamin malnutrition was seen in the majority of patients. A significant correlation between weight, BMI, arm circumference, blood lymphocyte count and the number of days spent in hospital was observed.

Elevated concentrations of IL-6 and IL-1ra in pleural fluid on postoperative day 1 are promising early markers of postoperative complications. Elevated concentrations of IL-6 and IL-1ra in serum are good early markers of severity of surgical injury and may reflect development of postoperative complications.
