    (2012) Ünal F.; Semizel E.; Serdar M.; Ecevit C.O.; Karaca Y.; Yilmaz E.M.; Kocaefe H.; Kasirga H.E.
    Introduction: Fecal calprotectin (FCP) can be found in high concentrations in inflammatory bowel disease due to the increase in leucocyte turnover in intestinal wall or increase of migration of neutrophils into the lumen. In this study, we aimed to determine the FCP values of the ulcerative colitis (UC) patients at the time of diagnosis and to investigate the applicability and effectiveness of this non-invasive method in the diagnosis of the disease, routinely. Materials and Methods: A total of 19 patients with UC (10 females, 9 males, age: 11.5±3.5 years old) whoose stool samples collected during the diagnosis period and 20 healthy controls (10 female, 10 male, age: 10.3±4.5 years old) were included in the study. Stool samples were collected for FCP analysis by ELISA method at the time of diagnosis and before the treatment period. Results: FCP values of the UC group were statistically higher than the control group. FCP values of the UC and control groups were 398.4 μg/gr stool (56.7-2450) and 19.4 μg/gr stool (2-81), respectively (p<0.005). FCP values of the patient group with mild activity index (n=8), and moderate-severe activity index (n=11) according to the Pediatric Ulcerative Colitis Activity Index were 267.6-μg/gr stool, and 435.2 μg/gr stool, respectively (r2: 0.40, p<0.05). There was not statistical difference between the FCP values of the patients with pancolitis (422.6 μg/gr stool) and with left-sided colitis, proctitis/sigmoiditis (371.7 μg/gr stool) (p>0.05). High CRP values (89.4%), elevation of erythrocyte sedimentation rate (84.2%), leukocytosis (73.6%), thrombocytosis (68.4%), anemia (89.4%), and hypoalbuminemia (52.6%) were found. Conclusions: FCP values of the UC patients were found to be statistically higher than the control group, and increase in FCP values has been observed with increasing disease activity. Therefore, we believe that the determination of FCP could be useful at the time of diagnosis and during follow-up of the patients with UC. © The Journal of Current Pediatrics, published by Galenos Publishing.

    Plasma selenium levels in celiac disease patients on a gluten -free diet; [Glutensiz diyet alan çölyak hastası çocuklarda serum selenyum düzeyleri]
    (Galenos Yayincilik,, 2012) Ünal F.; Umman C.; Tok A.C.; Semizel E.; Ecevit C.O.; Özdemir S.; Taneli F.; Kasirga E.
    Introduction: Celiac disease (CD) is a gluten-induced enteropathy that results in malabsorption of nutrients such as selenium. A high incidence of malignancy in CD has been previously reported. Selenium is known to have a protective role against cancer. This study aimed to investigate whether there is an effect on serum selenium levels in children with CD on a gluten-free diet. Materials and Methods: Serum levels of selenium were studied in 17 children (mean age 5.64±3.30 years) with CD and 20 age-and gender-matched healthy children. CD was diagnosed according to ESPGHAN criteria. All the patients were clinically well and had been on gluten-free diets for 11.11±1.98 (mean±SE) months. All patients were fully consistent with the diet. The concentration of selenium was determined by a periodically validated atomic absorption spectrometer (Perkin Elmer AAS 700 system). Wet ashing procedure was used for all samples and controls. Results: In CD group one child's (5.8%), and in control group three children's (%15) serum selenium levels were found under normal limits. There was no statistically significant difference between serum selenium levels and the duration of gluten free diet (p>0.05). There was no statistically significant difference in serum selenium levels between celiac patients (124.19±12.31 μg/L) and control group (92.47±12.06 μg/L), (p>0.05). Discussion: It can be concluded that, normal levels of serum selenium in children with CD can be achieved with fully compatible gluten-free diet and a balanced diet which supplies daily selenium requirement. © The Journal of Current Pediatrics, published by Galenos Publishing.
