Abstract

Purpose: The aim of this study was to investigate the thiol/disulfide balance as a marker of oxidative stress in children with vitamin B12 deficiency. Materials and Methods: Sixty one pediatric patient with vitamin B12 deficiency and 62 healthy children as a control group was included in the study. Vitamin B12, homocysteine, complete blood count, and thiol/disulfide balance parameters of the participants were measured. The relationship between thiol/disulfide balance parameters and vitamin B12 and homocysteine was investigated. Results: The groups were similar in terms of age and gender distribution. Median vitamin B12 level was 179 (98-199) pg/ml in the patient group and 298 (201-965) pg/ml in the control group. Median homocysteine level was 11.2 (0.08-64.3) µmol/L in the patient group and 12 (4.5-26.6) µmol/L in the control group. Median values of homocysteine levels were within the normal range in both groups. Between the patient and control groups; no significant difference was found in terms of homocysteine, native thiol, total thiol, disulfide, disulfide/native thiol ratio, disulfide/total thiol ratio and native thiol/total thiol ratio. There was no significant correlation between thiol/disulfide balance parameters and vitamin B12 and homocysteine levels in the patient and control groups. Conclusion: There was no significant increase in homocysteine level, since the vitamin B12 level was not significantly low in our patient group. It can be predicted that a vitamin B12 deficiency that does not increase homocysteine will not increase oxidative stress and therefore will not increase antioxidant capacity.

Özet

Amaç: Bu çalışmada, vitamin B12 eksikliği olan çocuklarda oksidatif stres belirteci olarak tiyol/disülfit dengesinin araştırılması amaçlanmıştır. Gereç ve Yöntem: Çalışmaya vitamin B12 eksikliği olan 61 çocuk hasta ve 62 sağlıklı çocuk kontrol grubu olarak dahil edildi. Katılımcıların vitamin B12, homosistein, tam kan sayımı ve tiyol/disülfit dengesi parametreleri ölçüldü. Grupların klinik ve laboratuvar parametreleri karşılaştırıldı. Tiyol/disülfit dengesi parametreleri ile vitamin B12 ve homosistein arasındaki ilişki araştırıldı. Bulgular: Gruplar yaş ve cinsiyet dağılımı açısından benzerdi. Medyan vitamin B12 düzeyi hasta grubunda 179 (98-199) pg/ml, kontrol grubunda 298 (201-965) pg/ml idi. Hasta ve kontrol grubu arasında; homosistein, nativ tiyol, total tiyol, disülfit, disülfit/nativ tiyol oranı, disülfit/total tiyol oranı ve nativ tiyol/total tiyol oranı açısından anlamlı fark saptanmadı. Hasta ve kontrol grubunda, tiyol/disülfit dengesi parametreleri ile vitamin B12 ve homosistein düzeyleri arasında anlamlı korelasyon saptanmadı. Sonuç: Hasta grubumuzda vitamin B12 düzeyinin belirgin düşük olmaması nedeniyle homosistein düzeyinde anlamlı artış olmadığı düşünülmüştür. Homosisteini artırmayan bir vitamin B12 eksikliğinin, oksidatif stresi artırmayacağı, dolayısıyla antioksidan kapasiteyi de artırmayacağı öngörülebilir.
