Objective:
It is well known that increased oxidative stress leads to tissue damage in beta-thalassemia (β-thal) patients. Thiols are one of the most important antioxidant agents, and thiol/disulfide (SH/SS) homeostasis is a novel oxidative stress marker. This study aimed to investigate the relationship of thiol levels, SH/SS homeostasis, and ischemia-modified albumin (IMA) in patients with β-thal.
Materials and Methods:
A hundred transfusion-dependent β-thal patients and 41 healthy controls were included in the study.
Results:
Native thiol, total thiol, disulfide, catalase, and IMA levels were significantly higher in the β-thal group compared with the control group (P<0.02). There were no correlation between serum ferritin level and SH/SS homeostasis, and weak positive correlations were found between serum ferritin and IMA (r=0.242, P=0.022).
Conclusions:
Our study results suggest that antioxidant systems try to compensate for peroxidative damage in the patients’ group and serum IMA level was found increased because of increased oxidative status. To the best of our knowledge, there has been no report evaluating plasma dynamic SH/SS homeostasis in β-thal patients.
Hydrothorax of the cerebrospinal fluid after a subarachnoid-pleural fistula is a rare condition. Subarachnoid-pleural fistula may appear after a trauma at the thoracolumbar vertebral column or iatrogenically after thoracotomy. A two years and four months old boy who was operated because of ganglioneuroblastoma was admitted to hospital due to respiratory distress. The chest roentgenogram obtained two months after thoracotomy, showed a pleural effusion at the left side and a chest tube was inserted. The craniospinal magnetic resonance imagining revealed subarachnoid-pleural fistula and lumbar external cerebrospinal fluid drainage was performed. The chest tube was removed by application of tetracycline between pleural layers. After the patient was discharged, respiratory distress reoccurred after 3 weeks and a chest tube was reinserted due to fluid at the left hemithorax. An external lumbar drainage was reapplied. The location of the fistula was determined by craniospinal magnetic resonance imagining and myelography. The fistula was surgically restored by a posterior approach and laminectomy. The cerebrospinal fluid drainage and chest tube was removed three days and seven days after the operation respectively. The patient was discharged at the 13 days after the operation. During periodical outpatient follow up the patient has no symptoms and is neurologically intact. Subarachnoid-pleural fistulas, usually do not regress spontaneously or respond to conservative methods. Invasive approaches including surgery may be needed to treat patients with subarachnoid-pleural fistulae.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
