Glutensiz Diyet Alan Çölyak Hastası Çocuklarda Serum Selenyum Düzeyleri

ÖZET Girifl: Çölyak hastalığı (ÇH) selenyum gibi besinlerin emilim bozukluğu ile sonuçlanan gluten bağımlı bir enteropatidir. ÇHnın yüksek malignite insidansı daha önceden bildirilmiştir. Selenyumun kansere karşı koruyucu bir rol oynadığı bilinmektedir. Bu çalışmada glutensiz diyet altındaki çocuklarda serum selenyum düzeyinin etkilenip etkilenmediğinin araştırılması amaçlandı. Gereç ve Yöntem: Serum selenyum düzeyleri ÇH olan 17 çocukta (ortalama yaş 5,64±3,30 yıl) ve aynı yaş ve cinsiyetteki 20 sağlıklı çocukta çalışıldı. ÇH tanısı ESPGHAN kriterlerine göre konuldu. Tüm hastalar klinik olarak iyiydi ve glutensiz diyeti 11,11±1,98 ay (ortalama±standart sapma) uygulamışlardı. Tüm hastalar diyete tamamen uyumlu idi. Selenyum konsantrasyonu periyodik olarak doğrulanmış atomik absorbsiyon spektrometresi (Perkin Elmer AAS 700 system) ile tespit edildi. Islak yakma işlemi tüm numuneler ve kontroller için kullanıldı. Bulgular: Serum selenyum düzeylerinin ÇH grubunda bir (%5,8), kontrol grubunda ise üç (%15) çocukta normal sınırların altında olduğu saptandı. Glutensiz diyet alım süresiyle serum selenyum düzeyleri arasında istatistiksel herhangi bir ilişki yoktu (p>0,05). Glutensiz diyet altındaki çölyaklı hastalarda (124,19±12,31 μg/L) serum selenyum düzeyleri kontrol grubunda yer alan sağlıklı çocuklardan (92,47±12,06 μg/L) farklı değildi (p>0,05). Sonuç: Çölyaklı çocuklarda normal serum selenyum düzeyleri hastaların glutensiz diyete tam uyumlu olmalarına ve günlük selenyum ihtiyacını karşılayacak şekilde dengeli beslenmelerine bağlı olabilir.

Plasma Selenium Levels in Celiac Disease Patients on a Gluten -Free Diet

SUMMARY Introduc tion: 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.
