One hundred and seven sessions of hemosorption were performed on 77 patients with severe ulcerative colitis. Clinically, improvement was demonstrated in the reduction of the signs of intoxication in 50 to 60 per cent of patients. Combination of hemosorption and anti-inflammatory medication allowed to achieve a remission or a marked improvement determined by clinical observation or endoscopy of 39 from 52 patients with a severe, total form of the disease, whereas toxic influence of sulfasalazine was controlled and extra-intestinal complications were weakened in 8 patients from 11. Thirteen patients were operated upon due to inefficiency of therapy. Hemosorption contributed to reduction of content of protein molecules with mean molecular weight (61 per cent), phenol (73 per cent), and endotoxin of gram-negative bacteria (50 per cent). Dynamics of acute phase reactants and humoral immune factors testifies to a weak anti-inflammatory action of hemosorption. Reduced levels of plasma protein, albumin, potassium and cholesterol were corrected or spontaneously returned to normal.

Diagnosis of vitamin D deficiency and its management is the most difficult problem of modern neonatology.The objective: to study the concentration of 25(OH)D3 in newborns of St. Petersburg depending on the presence of congenital malformations (CM).Subjects and methods. 60 newborns were examined, their gestational age made 39.4 (38-41) weeks. Children were divided into 2 groups: Group 1 – healthy children, Group 2 – children with CM.Results. Regardless of the presence of CM, the calcifedol plasma concentration was below 15 ng/ml. It was found that children with CM whose plasma calcifedol concentration was below 8.0 ng/ml needed long-term invasive mechanical ventilation (80.0 vs 40.0 hours; p < 0.005) and longer treatment in ICU (7.0 vs 4.0; p < 0,002). Negative correlations were revealed between calcifedol concentration, duration of narcotic analgesics administration (R = -0.44; p = 0.01), duration of mechanical ventilation (R = -0.49; p = 0.003) and stay in ICU (R = -0.54; p = 0.001).Conclusion. The most pronounced deficiency of calcifedol was in children with severe CM requiring long-term treatment in ICU.
