Acute phase proteins and markers of proteosynthetic activity reflect the clinical activity in Crohn´s disease (CD). The impact of anti-tumor necrosis factor antibody (anti-TNF) therapy on serum levels of acute phase proteins and proteosynthetic markers was studied. Fourteen patients with active CD were treated with 5 mg per kg of anti-TNF in intravenous infusion. Clinical activity (assessed by Crohn´s disease activity index - CDAI), α-1-acid glycoprotein, haptoglobin, cholinesterase and prealbumin were assessed before and in months 1 and 5 after treatment. A sustained decrease in CDAI was observed. This was accompanied by a significant decrease in α-1-acid glycoprotein and haptoglobin in month 1 (p=0.005 and p=0.01, respectively) while in month 5 the levels of both acute phase proteins rose significantly (p=0.003 for α-1-acid glycoprotein and p=0.02 for haptoglobin). Cholinesterase and prealbumin significantly increased in month 1 after the treatment (p=0.02 and p=0.0006, respectively), the increase was sustained in cholinesterase while prealbumin levels diminished in month 5. We conclude that the clinical improvement after anti-TNF therapy for CD is accompanied by changes of acute phase proteins and proteosynthetic markers. The assessment of these laboratory markers may be useful in the management of CD patients treated with anti-TNF., V. Kupčová, L. Turecký, Z. Detková, M. Príkazská, A.

Administration of anti-tumor necrosis factor antibody (anti-TNF, infliximab) down-regulates T helper 1 (Th 1) cytokines production in intestinal mucosa of patients with Crohn´s disease (CD). Interleukin 10 (IL-10) is thought to be involved in CD pathogenesis through regulation of the Th 1 response. The aim of this study was to determine the IL-10 response in CD patients treated with anti-TNF. Fourteen patients with active CD received 5 mg/kg of infliximab; clinical activity assessed by Crohn´s Disease Activity Index (CDAI), α1-acid glycoprotein and serum IL-10 were determined before and after treatment, in month 0, 1 and 5. In the group with a good clinical response, IL-10 levels diminished significantly in month 1 (p<0.05) and remained decreased in month 5. The group with a lower response showed a significant increase in IL-10 levels in month 1 (p<0.05). α1-acid glycoprotein levels obtained before treatment were significantly elevated in the group with a good clinical response (p<0.05) and a significant decrease in month 1 was observed in this group (p<0.05). These observations suggest that a pattern of IL-10 response might be related to the clinical response to anti-TNF treatment in CD., Z. Detková, V. Kupčová, M. Príkazská, L. Turecký, S. Weissová, E.

Osteoporosis in chronic diseases is very frequent and pathogenetically varied. It complicates the course of the underlying disease by the occurrence of fractures, which aggravate the quality of life and increase the mortality of patients from the underlying disease. The secondary deterioration of bone quality in chronic diseases, such as diabetes of type 1 and type 2 and/or other endocrine and metabolic disorders, as well as inflammatory diseases, including rheumatoid arthritis - are mostly associated with structural changes to collagen, altered bone turnover, increased cortical porosity and damage to the trabecular and cortical microarchitecture. Mechanisms of development of osteoporosis in some inborn or acquired disorders are discussed., I. Zofkova, P. Nemcikova., and Obsahuje bibliografii
Fatty acid (FA) profiles as potentially relevant components of Crohn’s disease (CD) have been insufficiently analysed. We sought to explore the plasma profiles of n-3 and n-6 polyunsaturated fatty acids (PUFAs) in newly diagnosed untreated active CD. We included 26 consecutive CD pediatric patients (<19 years) and 14 healthy controls (HCs). Disease characteristics, including inflammatory markers, dietary histories, and the Pediatric Crohn’s Disease Activity Index (PCDAI), were obtained. The profiles of plasma FAs in plasma lipid classes were analysed by gas chromatography with FID detection of methyl esters. The erythrocyte sedimentation rate, C-reactive protein level and fecal calprotectin level (all p<0.001) were significantly higher in CD patients than in HCs. Most changes were observed in plasma phospholipids (PLs), such as a higher content of n-3 and changes in n-6 long-chain PUFAs in the CD group. The CD group had a lower ratio of n-6/n-3 PUFAs in PLs (p<0.001) and triacylglycerols (TAGs) (p<0.01). Correlations of the FA content in plasma PLs with disease activity scores of CD were also observed, which were positive for the sum of monounsaturated fatty acids (MUFAs) as well as oleic acid (18:1n-9) (both p<0.05). The metabolism of PUFAs is significantly altered even in treatment-naïve newly diagnosed active pediatric CD, and the content of major FAs in PLs correlates with disease activity and inflammatory markers, thus probably contributing to the still unclear early disease pathogenesis., Jan Schwarz, Marek Vecka, František Stožický, Renáta Pomahačová, Barbora Staňková, Eva Tvrzická, Marcela Kreslová, Romana Zahálková, Josef Sýkora., and Obsahuje bibliografii
