Introductıon
Iron overload is one of the contributing cause of oxidative stress
in thalassemic patients. As iron excesses transferrin capacity a low
molecular weight iron called non-transferrin bound iron (NTBI) and
its portion called labil plasma iron (LPI) occurs and causes production
of oxygen-free radicals resulting in depletion of protective antioxidants.
Also auto-oxidation of globin chains and premature hemolysis of red cell
enhances the oxidative damage at thalassemic patients [1-3]. Oxidative
stress induces apoptosis, leakage of protones from mitochondria
and increases oxygen depletion causing damage to cell and organelle
membranes. e long term clinical consequences of this process are
hearth failure, liver fibrosis or cirrhosis and endocrinopathies e
balance between the prooxidant and antioxidant levels becomes
impaired while a decrease occurs in levels of antioxidant enzymes,
an increase occurs in levels of MDA which is a good marker of lipid
peroxidation [4].
Treatment strategies of thalassemic patients are regular transfusion
and chelation therapy to main aim is to reduce iron overload and
NTBI. ere are so many studies about thalassemia and the effects of
antoxidants on thalassemia patients. In recent years use of specially
plant origin antioxidants, such has fermented papaya preparation has
been shown to reduce the oxidative stress and damage on several organs
[3]. Silymarin, a flavonoid, acts as iron chelator and also increases
intracellular glutathione content, suggesting to restore cellular
antioxidant defences [5]. Oral vitamin E supplies an amelioration at
rate of antioxidant/oxidant levels and inhibition at lipid peroxidation in
patients with thalassemia [6].
Capparis, a member of Capparidacaeae family, is used in
phytomedicine as anti-oxidative, hypolipidemic, anti-inflammatory and
anti-hepatotoxic agent. Its the buds contain lipids, alcaloids, flavanoid
and polyphenols. It is known that the antioxidant effect of capparis is
formed the composition of flavanoids and polyphenols in its compund
[7-10]. In a study done by Yadav et al it has been shown that capparis
decidua extracts possess antihepatotoxic activity against alloxan
induced hepatotoxicity and furthermore a decrease in oxidative stress
has been observed [11]. Antihyperglycaemic and antioxidant effect of
rutin, a polyphenolic flavonoid in normal and streptozotocin-induced
diabetic Wistar rats studied. A decrease in fasting blood glucose level
and an increase in insulin level observed. Additionally a decrease in
lipid peroxidation products and an increase in both enzymatic and non
enzymatic antioxidant levels observed [12].
It has been shown that iron chelator agents have antioxidant effect
on thalassemic patients. Aſter incubation of thalassemic red cell with
deferiprone it has been observed that MDA levels decreased [13].
Walter et al. [14] have been compared the antioxidant effectiveness of
Abstract
Iron overload and auto-oxidation of unpaired globin chains is the main cause of oxidative stress in thalassemia.
We aimed to show the additive antioxidant effect of capparis and deferasirox in thalassemic patients. A
total number of 40 thalassemia major patient aged between 7-30 years, who have been taken regular red cell
15 cc/kg/month to maintain Hb >10 gr/dl) and chelation (30 mg/kg/day ICL-670) for one year are involved. They
were divided into two groups as control and study group randomly. Both study and control groups were followed
by regular transfusion and chelation therapy. In addition study group has been taken capparis marmalade at the
breakfast with a dose of a dessert-spoon (12.5 gr) younger than 10 years and a soup-spoon (25 gr) older than 10
years for 6 months. Hematological and biochemical parameters, ferritin at every month and oxidative-antioxidant
status (MDA, CAT, Gpx, SOD) were measured at the beginning and at the end of the study. Serum ferritin and
MDA levels declined significiantly in both groups (for ferritin; control group p=0.00; study group p=0.00) during
the study but a much more decrease occured at MDA levels in the capparis given group (p=0.02). There was no
statistically significant difference between the groups at the initial and last SOD CAT, GPX, SOD levels. Further
more in the study group a significant decrease in liver function tests has been occured (AST p= 0.05, ALT p=
0.01). The high levels of MDA in iron overloaded thalassemic patients is the best marker of oxidative stres.
Generally decreased iron burden was associated with decreased oxidant damage. In vitro it was shown that
iron chelators such as deferoxamine and deferipron neutrolyse intraselluler free iron and inhibits oxidation. Our
findings suggest that combination of capparis with deferasirox maybe have additive effect on decreasing the
oxidative damage and hepatoxicity.
