To examine the correlation between iron, ferritin concentrations, and infection in individuals with beta-thalassemia major and beta-thalassemia minor compared with healthy subjects.
It involved 90 participants, thirty patients with thalassemia major and thirty patients with thalassemia minor compared with thirty healthy controls. Saliva samples were obtained and cultivated to isolate, identify, and calculate the viable colony count of in (cfu/ml). In contrast, serum levels of iron and ferritin were quantified using chemical analyzers.
Showed that 73.33% of thalassemia major group exhibited oral colonization, which is significantly higher than that of thalassemia minor group 40% and control group 6.67%. Biochemical analyses revealed significantly higher iron 278.82 μg/dl and ferritin 2783.80 ng/ml levels in major group p<0.001 when compared with both thalassemia minor group 122.652 μg/dl, 74.723 ng/ml and control groups 127.438 μg/dl and 63.150 ng/ml respectively. colony count in saliva was significantly elevated in beta-thalassemia major, as compared with beta-thalassemia minor group and control group.
Findings suggest that iron overload, which results from recurrent blood transfusions and causes immune dysfunction, contributes to higher risk of oral fungal infections in Beta-thalassemia patients compared with controls.
与健康受试者相比,研究重型β地中海贫血和轻型β地中海贫血患者铁、铁蛋白浓度与感染之间的相关性。
研究涉及90名参与者,30名重型地中海贫血患者、30名轻型地中海贫血患者以及30名健康对照者。采集唾液样本并进行培养,以分离、鉴定并计算(每毫升菌落形成单位)中的活菌菌落数。相比之下,使用化学分析仪对血清铁和铁蛋白水平进行定量分析。
结果显示,重型地中海贫血组73.33%的患者口腔存在念珠菌定植,这显著高于轻型地中海贫血组的40%和对照组的6.67%。生化分析显示,与轻型地中海贫血组(铁水平122.652μg/dl、铁蛋白水平74.723ng/ml)和对照组(铁水平127.438μg/dl、铁蛋白水平63.150ng/ml)相比,重型地中海贫血组的铁水平(278.82μg/dl)和铁蛋白水平(2783.80ng/ml)显著更高(p<0.001)。与轻型地中海贫血组和对照组相比,重型β地中海贫血患者唾液中的念珠菌菌落数显著升高。
研究结果表明,反复输血导致的铁过载会引起免疫功能障碍,与对照组相比,这会使β地中海贫血患者发生口腔真菌感染的风险更高。
