Abstract
Atherosclerosis is a chronic vascular inflammatory disease associated to oxidative stress and endothelial dysfunction. It is characterized by lipid accumulation in the arterial wall, increased hyperlipidemia, oxidative stress, lipid peroxidation, and protein oxidation. Our study included 45 patients ages of 40-60 and 45 healthy volunteers with similar demographic characteristics without any chronic disease as well. Fasting plasma glucose, BUN, creatinine, LDL-cholesterol, HDL-cholesterol, triglyceride, total cholesterol, HbA1c, and C-reactive protein (CRP) levels were measured using commercial kits by autoanalyzer. The oxidative stress biomarkers total oxidant status (TOS), total antioxidant status (TAS), total thiol (TT), native thiol (NT), catalase (CAT), paraoxonase (PON1), and arylesterase (ARES) enzyme activities were measured using photometric methods. The inflammatory biomarkers interleukin 1 beta (IL-1β), tumor necrosis factor-α (TNF-α), presepsin (PSPN), and raftlin (RFTN1) levels were measured with ELISA Kits. Oxidative stress index (OSI) and disulfide (DIS) were calculated. The clinical, biochemical biomarkers such as BUN, creatinine, HDL, LDL, total cholesterol, triglyceride, and CRP levels were found to be higher than the control group and lower post-treatment compared to the pre-treatment group (p <0.001). The oxidative stress parameters, TOS, OSI, and DIS levels were found to be higher than the control group, and the levels before the treatment were statistically significantly higher than after the treatment (p < 0.001). Antioxidant biomarkers TAS, TT, and NT levels were low in the patient group. Inflammatory biomarkers were highest before treatment and decreased with treatment. Oxidative stress and inflammation, which increased in atherosclerosis patients may guide disease prognosis and treatment strategies.

Abstract
Objectives Rheumatoid arthritis is a multisystemic inflammatory disease characterized by destruction of the joints. An effective treatment method of the disease has not been developed yet. The aim of the present study is to evaluate the effects of bee (Apis mellifera anatoliaca) venom (BV) on serum inflammatory parameters, serum antioxidant load and clinical parameters of experimentally induced adjuvant arthritis in rats. Material and methods A total of 35 Wistar albino male rats were used. The animals were divided into 5 groups. First group animals served as negative controls. The second, third, fourth and fifth groups were used for experimental arthritis induction. Following clinical development of arthritis, the first group was subcutaneously administered 0.2 ml of physiological saline, and the second, third and fourth groups were treated subcutaneously with 2 µg/kg, 4 µg/kg and 20 µg/kg once a week three times. Physiological saline injected fifth group animals were used as a sham-treatment group. Clinical observations and evaluation of arthritis were made at the 15th day, and at the end of the experiment. The levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase, paraoxonase, serum aryl esterase, high-sensitivity C reactive protein, interleukin 1β (IL-1β), interleukin 6 (IL-6), and tumor necrosis factor alpha (TNF-α) were determined in cardiac blood samples taken at the end of the 29th day. Results From the data, total oxidant level (TOL) and oxidative stress index (OSI) were calculated. Significant improvements were observed in the clinical signs of arthritis and inflammatory markers such as in IL-1β, TNF-α, IL-6 and TOL and OSI in the 20.0 µg/kg BV-administered group. Bee venom administration did not cause any significant increase in ALT and AST values or signs of liver toxicity. Conclusions Bee venom treatment was effective in alleviation of symptoms of the experimental rat adjuvant arthritis by means of clinical observation and serum inflammatory markers.

Abstract
Paraoxonase 1 (PON1) is an A-esterase calcium-dependent enzyme that is associated with high-density lipoprotein (HDL) and capable of hydrolyzing a wide variety of substrates, including organophosphate (OP) pesticides. The PON1 phenotype can be modulated by multiple internal and external factors, thereby affecting the catalytic capacity of the enzyme. The aim of this study was to evaluate factors that could modulate PON1 activity in a sample occupationally exposed to pesticides. A cross-sectional, descriptive, and analytical study was carried out with 240 workers. The participants were stratified according to their level of pesticide exposure as reference, moderate-exposure, and high-exposure groups. PON1 activities (arylesterase/AREase, CMPAase, and ssPONase (salt-stimulated)) were determined by spectrophotometry, and the Q192R and L55MPON1 genotypes by real-time PCR. The most frequent genotypes were heterozygous (QR) and homozygous (LL) for PON1Q192R and PON1L55M polymorphisms, respectively. The internal factors associated with the activity of PON1 were the PON1 genotypes (55 and 192) and biochemical parameters related to the lipid profile, in contrast, various external factors related to diet and harmful habits as well as with exposure to pesticides were associated with the activity of PON1. However, using a multivariate mixed ordinal regression model, we found a significant reduction of ssPONase activity in the high-exposure group compared with the reference group only in haplotypes QQLL and RRLL.

Abstract
Objective The purposes of this study is to evaluate the variations of total antioxidant status (TAS) and total oxidant status (TOS) levels in the treatment process of carbon monoxide poisoning (COP) and to learn more about the pathophysiology of COP. Methods Between 2011 and 2012, 113 patients were admitted to our emergency department with acute COP, and 50 healthy volunteers were used as a control group in this study. Serum, plasma and erythrocyte components were prepared for all the COP patients on admission. They were repeated at the 90th and 180th minute of treatment. The samples were taken once from the control group. Serum oxidant/antioxidant status levels and carboxyhaemoglobin (COHb) were measured. Ratio of TOS to TAS, known as oxidative stress index (OSI) was calculated. Results No correlation was observed among age, gender, COHb level, with the levels of TAS, TOS, and OSI. Admission levels of TOS and OSI in patients with COP were higher than that observed at 90th minutes (p<0.001). These values were also higher in COP patients compared to control group (p<0.001). On the other hand, no statistical differences were observed in TAS levels between the study and control groups (p>0.05). Conclusions Our results show that serum TOS and OSI levels increase in COP patients. Oxidative stress should play a role in the pathophysiology of COP. (Hong Kong j.emerg.med. 2013;20:352-358)

Abstract
INTRODUCTION In this study we aimed to detect paraoxonase 1 (PON-1) activity in iron deficiency anemia (IDA) and to compare it with healthy controls by observing the change after iron therapy. MATERIAL AND METHODS In this study, 50 adult patients with IDA and 40 healthy subjects were enrolled. All patients were analyzed at the beginning and after treatment according to laboratory assessments. RESULTS Mean paraoxonase and arylesterase activities in the iron deficiency anemia group were significantly lower than mean activities of the control group (102.4 ±19.2 U/l and 163.3 ±13.68 U/l, respectively and 157.3 ±26.4 U/l and 256.1 ±24.6 U/l, respectively; p = 0.0001 for both). Paraoxonase and arylesterase activities significantly increased after treatment for IDA (143.2 ±13.9 and 197.6 ±27.9 U/l, respectively, p = 0.0001). Mean activities after treatment with iron were significantly lower than mean activities in the control group (p = 0.002; p = 0.0001 respectively). CONCLUSIONS Paraoxonase and arylesterase activities in patients with IDA significantly increased after treatment with iron therapy. In adults IDA may also be one of the factors associated with increased risk of atherosclerosis.

Abstract
OBJECTIVES Otosclerosis is a disease involving abnormal bone turnover in the human otic capsule that results in hearing loss. Several hypotheses have been suggested for the etiopathogenesis of otosclerosis; however, its etiology remains unclear. METHODS This study evaluated the correlation between otosclerosis and levels of paraoxonase-1 (PON1), arylesterase, total antioxidant status, total oxidant status (TOS), oxidative stress index (OSI), total sulfhydryl (-SH) groups, lipid hydroperoxide, and ceruloplasmin in the serum of otosclerosis patients and healthy subjects with respect to oxidative stress. RESULTS In our study, TOS and OSI levels were higher in the otosclerosis patients than in the controls. The PON1 levels showed that oxidative stress was severe, and as a result, antioxidants were consumed and depleted. DISCUSSION When an imbalance between oxygen free radical production and antioxidative defense mechanisms occurs, reactive oxygen species levels may increase, which in turn may damage cells and tissues through the peroxidation of phospholipid membrane structures. The body initially responds with increased antioxidant production, but if the oxidative stress is severe, decreased antioxidant levels may result. This study reports expression levels of oxidative stress species in otosclerosis patients.

Abstract
OBJECTIVE Altered paraoxonase (PON) and arylesterase (ARE) activities have been shown in anemic chronic kidney disease (CKD) patients and in iron deficiency anemia (IDA) patients. Whether accompanying anemia alone is responsible for this diminished PON and ARE activities in CKD patients or an additive factor for this is not well studied. Therefore, we tried to clarify this issue here. METHODS A total of 82 subjects that consisted of 19 patients with IDA (group 1), 23 anemic CKD patients (group 2), and 40 age and sex matched healthy subjects (group 3) were enrolled. Carotid intima media thickness (CIMT), serum total thiol (-SH), PON, and ARE activities of the participants were analyzed. RESULTS Group 2 patients had significantly lowest serum levels of Total -SH, PON and ARE. Further comparison showed that total -SH, PON and ARE levels were lower in group 1 than group 3 (p = 0.0001 in both). Regarding comparison of group 1 and 2, only serum ARE levels were significantly lower in group 2 (p = 0.001). PON activity was not different between group 1 and group 2 whereas ARE activity was lower in group 2 than groups 1 and 3. In addition, correlation analysis showed that CIMT was negatively correlated with PON and ARE. CONCLUSIONS This markedly decreased ARE activity in CKD patients, which could not be explained by the anemia alone, may have a role in the pathogenesis of increased atherosclerosis in such patients. Still further studies are needed to certain this.

Abstract
BACKGROUND AND AIMS Iron deficiency anemia (IDA) affects around 20-30% of adults worldwide. An association between IDA and cardiovascular disease (CVD) has been reported. Oxidative stress, inflammation and low concentration of high-density lipoproteins (HDL) were implicated on endothelial dysfunction and CVD in IDA. We studied the effects of iron deficiency and of an intravenous iron administration on oxidative stress and HDL characteristics in IDA women. METHODS Two studies in IDA women are presented: a case-control study, including 18 patients and 18 age-matched healthy women, and a follow-up study 72hr after the administration of intravenous iron (n = 16). Lipids, malondialdehyde, cholesteryl ester transfer protein (CETP), paraoxonase-1 (PON-1) and HDL chemical composition and functionality (cholesterol efflux and antioxidative activity) were measured. Cell cholesterol efflux from iron-deficient macrophages to a reference HDL was also evaluated. RESULTS IDA patients showed higher triglycerides and CETP activity and lower HDL-C than controls (all p < 0.001). HDL particles from IDA patients showed higher triglyceride content (+30%,p < 0.05) and lower antioxidative capacity (-23%,p < 0.05). Although HDL-mediated cholesterol efflux was similar between the patients and controls, iron deficiency provoked a significant reduction in macrophage cholesterol efflux (-25%,p < 0.05). Arylesterase activity of PON-1 was significantly lower in IDA patients than controls (-16%,p < 0.05). The intravenous administration of iron was associated with a decrease in malondialdehyde levels and an increase in arylesterase activity of PON-1 (-22% and +18%, respectively, p < 0.05). CONCLUSION IDA is associated with oxidative stress and functionally deficient HDL particles. It remains to be determined if such alterations suffice to impair endothelial function in IDA.

Abstract
The aim of this study was to examine the oxidative status in Egyptian patients suffering chronic fascioliasis. The relationship between serum malondialdehyde (MDA) levels, superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX) activities was investigated in relation to the level of liver enzymes; ALT and AST compared to healthy controls. Twenty patients versus ten controls were included in the study. Among cases the MDA, CAT, AST and ALT were higher than controls, while SOD and GPX higher values were present among controls. There was a highly significant difference between cases and controls as regard MDA, CAT, SOD, GPX, and AST, and a significant difference regarding ALT. The findings of increased serum lipid peroxidation and decreased antioxidant enzymes in erythrocytes of chronic fascioliasis patients indicated the presence of persistent inflammation and oxidative stress which confirms the underlying pathogenesis and reflected the stage of infection providing a baseline data for comparison between normal and infected patients guided by the level of liver enzymes in relation to oxidative status.

Abstract
It is well known that paraoxonase-1 (PON1) activity may decrease during the course of infection and inflammation. The aim of this study was to investigate serum PON1 activity, oxidative status, and thiols levels in patients with acute brucellosis. In addition, we investigated the PON1 phenotype in patients with acute brucellosis. Thirty patients with acute brucellosis and 35 healthy controls were enrolled. Serum paraoxonase and arylesterase activities, thiols levels, lipid hydroperoxide levels, total antioxidant capacity (TAC), total oxidant status (TOS) and oxidative stress index (OSI) were determined. Serum basal and salt-stimulated paraoxonase-arylesterase activities, TAC levels and thiols levels were significantly lower in patients with acute brucellosis than controls (for all, p < 0.05), while LOOH levels, TOS levels, and OSI values were significantly higher (for all, p < 0.05). We concluded that oxidative stress is increased, while serum PON1 activity is decreased in patients with acute brucellosis. These results indicate that lower PON1 activity is associated with oxidant-antioxidant imbalance.

Abstract
BACKGROUND Carbon monoxide poisoning (COP) is an important cause of mortality and morbidity worldwide. This study was to investigate the levels of serum paraoxonase (PON), arylesterase (ARYL), ceruloplasmin (Cp), and sulfhydryl (-SH) in the treatment of COP, and to further understand the pathophysiology of COP. METHODS This prospective study comprised 107 individuals with COP (group 1) and 50 healthy volunteers (group 2). Serum, plasma, and erythrocyte samples were taken on admission from all participants with COP. This process was repeated in the 90(th) and 180(th) minutes of treatment. Samples were taken from the control group only once. The levels of plasma PON, ARYL, Cp activity and -SH were measured in both groups. RESULTS Age, gender, and carboxyhemoglobin level were not correlated with PON, ARYL, Cp, and -SH levels. PON, ARYL, and -SH levels were significantly decreased in group 1 compared with group 2. Conversely, Cp was significantly elevated in group 1 in contrast to group 2. Although ARYL was lower on admission in patients with COP than that was observed in the 90(th) and 180(th) minutes (P<0.001), Cp was higher on admission than at the other time points (P<0.001). CONCLUSIONS Participants with COP had decreased levels of antioxidants (PON, ARLY, and -SH). COP represses the antioxidant system.

Abstract
Epilepsy is the most common chronic neurological illness in childhood and adolescence. The aim of this study was to investigate paraoxonase and arylesterase activities along with oxidative status parameters in children with intractable epilepsy. The study comprised 42 subjects with intractable epilepsy and a control group of 35 healthy subjects. Serum paraoxonase and arylesterase activities, and lipid hydroperoxide levels were determined. All paraoxonase and arylesterase activities were significantly lower in the intractable epilepsy subjects than in the controls (P<0.001), whereas lipid hydroperoxide levels were significantly higher (P<0.05). In conclusion, paraoxonase and arylesterase activities were decreased and the lipid hydroperoxide level was increased in patients with intractable epilepsy. These results showed that intractable epilepsy subjects may be more prone to the development of atherosclerosis.

Abstract
BACKGROUND Snake bites are an important cause of mortality and morbidity worldwide, especially in rural areas. OBJECTIVE The aim of this study was to investigate serum paraoxonase (PON), arylesterase (ARLY), ceruloplasmin (Cp), and myeloperoxidase (MPO) activity and lipid hydroperoxide (LOOH) and total sulfhydryl group (-SH) levels in patients with snake venom poisoning. METHODS The study included 49 patients with snake bite envenomation (Group 1) and 39 healthy volunteers as the control group (Group 2). Plasma PON, ARLY, Cp, and MPO activity and LOOH and -SH levels were measured. Laboratory measurements of 20 patients with snake bite envenomation (Group 3) were performed again after treatment. RESULTS PON and ARLY activity and -SH levels were significantly decreased in Group 1 compared with those in Group 2. Cp and MPO activity and LOOH levels were significantly elevated in Group 1 compared with those in Group 2. PON and ARLY activity were significantly elevated in Group 3 compared with those in Group 1. Cp and MPO activity and LOOH levels were significantly decreased in Group 3 compared with those in Group 1. CONCLUSIONS Patients with snake bite envenomation had increased oxidants (MPO and LOOH) and decreased antioxidants (PON, ARLY, and -SH). Results obtained in this study demonstrate that snake bites are associated with a shift to oxidative status. Therapy with antioxidants can lead to an increase in the antioxidant defense system, and thus improvements in clinical symptoms.

Abstract
INTRODUCTION Previous studies have suggested that oxidative stress may play an important role in the pathogenesis of alopecia areata (AA) but these reports are limited and conflicting. OBJECTIVES The aim of this study was to investigate serum paraoxonase-1 (PON1) activity and oxidative status in subjects with AA. MATERIALS AND METHODS Thirty-nine subjects with AA and 39 healthy controls were enrolled. Serum PON1 activity, total antioxidant capacity (TAC), total oxidant status (TOS) and oxidative stress index (OSI) were determined. RESULTS Serum TAC levels and PON1 activity were significantly lower in the subjects with AA than controls (p = 0.038, p = 0.001, respectively), whereas TOS levels and OSI were significantly higher (both, p = 0.001) in the subjects with AA. CONCLUSIONS Our results suggest that reduced PON1 activity may be related to increased oxidant and decreased antioxidant levels. These data indicated that oxidant/antioxidant imbalance may play a role in the etiopathogenesis of AA.

Abstract
HDL-associated paraoxonase 1 (PON1) activity has been consistently associated with cardiovascular and other diseases. Vitamins C and E intake have previously been positively associated with PON1 in a subset of the Carotid Lesion Epidemiology and Risk (CLEAR) cohort. The goal of this study was to replicate these findings and determine whether other nutrient intake affected PON1 activity. To predict nutrient and mineral intake values, 1,402 subjects completed a standardized food frequency survey of their dietary habits over the past year. Stepwise regression was used to evaluate dietary and covariate effects on PON1 arylesterase activity. Five dietary components, cholesterol (P < 2.0 × 10(-16)), alcohol (P = 8.51 × 10(-8)), vitamin C (P = 7.97 × 10(-5)), iron (P = 0.0026), and folic acid (0.037) were independently predictive of PON1 activity. Dietary cholesterol was positively associated and predicted 5.5% of PON1 activity, second in variance explained. This study presents a novel finding of dietary cholesterol, iron, and folic acid predicting PON1 activity in humans and confirms prior reported associations, including that with vitamin C. Identifying and understanding environmental factors that affect PON1 activity is necessary to understand its role and that of HDL in human disease.

Abstract
Iron is an essential micronutrient which is required in a relatively narrow range for maintaining metabolic homeostasis and genome stability. Iron participates in oxygen transport and mitochondrial respiration as well as in antioxidant and nucleic acid metabolism. Iron deficiency impairs these biological pathways, leading to oxidative stress and possibly carcinogenesis. Iron overload has been linked to genome instability as well as to cancer risk increase, as seen in hereditary hemochromatosis. Iron is an extremely reactive transition metal that can interact with hydrogen peroxide to generate hydroxyl radicals that form the 8-hydroxy-guanine adduct, cause point mutations as well as DNA single and double strand breaks. Iron overload also induces DNA hypermethylation and can reduce telomere length. The current Recommended Dietary Allowances (RDA) for iron, according with Institute of Medicine Dietary Reference Intake (DRI), is based in the concept of preventing anemia, and ranges from 7mg/day to 18mg/day depending on life stage and gender. Pregnant women need 27mg/day. The maximum safety level for iron intake, the Upper Level (UL), is 40-45mg/day, based on the prevention of gastrointestinal distress associated to high iron intakes. Preliminary evidence indicates that 20mg/day iron, an intake slightly higher than the RDA, may reduce the risk of gastrointestinal cancer in the elderly as well as increasing genome stability in lymphocytes of children and adolescents. Current dietary recommendations do not consider the concept of genome stability which is of concern because damage to the genome has been linked to the origin and progression of many diseases and is the most fundamental pathology. Given the importance of iron for homeostasis and its potential influence over genome stability and cancer it is recommended to conduct further studies that conclusively define these relationships.

Abstract
Paraoxonase-1 is an esterase enzyme and it has 3 types of activity, namely paraoxonase, arylesterase, and diazoxonase. It has been reported that paraoxonase-1 deficiency is related to increased susceptibility to development of atherosclerosis and cardiovascular disease. The aim of this study was to investigate serum paraoxonase and arylesterase activities in children with iron deficiency anemia and vitamin B(12) deficiency anemia. Thirty children with iron deficiency anemia, 30 children with vitamin B(12) deficiency anemia, and 40 healthy children aged 6 months to 6 years were enrolled in this study. Serum paraoxonase and arylesterase activities were measured with a spectrophotometer by using commercially available kits. Mean paraoxonase and arylesterase activities in vitamin B(12) deficiency anemia group (103 ± 73 and 102 ± 41 U/L, respectively) were significantly lower than mean activities of control group (188 ± 100 and 147 ± 34 U/L, respectively; P < .001 for both) and iron deficiency anemia group (165 ± 103 and 138 ± 39 U/L, respectively; P < .05, P < .001), whereas there were no significant differences between iron deficiency anemia and control groups (P > .05). Paraoxonase and arylesterase activities significantly increased after treatment with vitamin B(12) in vitamin B(12) deficiency anemia; however, there were no significant changes in the activities of these enzymes after iron treatment in iron deficiency anemia group. Important correlations were found between vitamin B(12) levels and both paraoxonase and arylesterase activities (r = .367, P < .001; r = .445, P < .001). Our results suggest that vitamin B(12) deficiency anemia causes important reductions in paraoxonase and arylesterase activities, and after vitamin B(12) therapy the activities of these enzymes returned to near-normal levels.

Abstract
OBJECTIVES The aim of this study was to investigate serum paraoxonase, arylesterase activities along with determination of oxidative status via measurement of total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) in children with recurrent adenotonsillitis during pre- and post-adenotonsillectomy period and to compare results with data from healthy subjects. METHODS We performed a prospective controlled trial on adenoidectomy and/or tonsillectomy patients. A total of 47 subjects, including 22 patients with recurrent adenotonsillitis and 25 healthy controls were enrolled in this study. Peripheral venous blood samples were taken from patients before adenotonsillectomy and a second sample was obtained in first month postoperatively. In the control group, blood samples from healthy volunteers were collected for one time only. Serum paraoxonase, arylesterase activities, TOS, TAS and OSI levels were measured. RESULTS Paraoxonase, arylesterase activity, TAS and TOS levels were significantly higher in preoperative group compared to control group (P<0.001, P=0.003, 0.003 and 0.005, respectively). However, OSI level was similar in preoperative group compared to control group (P=0.25). In the post-operative group, paraoxonase, arylesterase activities, TAS and OSI levels were lower as compared to preoperative group but differences were statistically insignificant (P=0.483, 0.265, 0.149 and 0.090, respectively). TOS level in post-operative group was significantly lower than the preoperative group (P<0.001). In the post-operative group, paraoxonase and arylesterase activities were significantly higher as compared to control group (P=0.004 and 0.02, respectively). TOS and OSI levels were significantly lower in post-operative group compared to control group (P=0.001 and 0.02, respectively). However, TAS was similar between post-operative and control groups (P=0.464). CONCLUSIONS Based on data obtained from this study, we may state that paraoxonase, arylesterase activities with TAS, TOS and OSI levels of patients with chronic adenotonsillitis shows alterations due to oxidant/antioxidant imbalance induced by frequent infections.

Abstract
There are few good biomarkers of iron deficiency anemia (IDA). Since IDA patients have evidence for increased oxidative stress, we used mass spectrometry (MS) [i.e. matrix-assisted laser desorption/ionization (MALDI) and electrospray ionization] to identify novel biomarkers. Using MALDI-MS, the following oxidative modifications of hemoglobin with the following mass-to-charge ratios were identified: 1,087.5 (α32-40), 1,545.7 (α17-31), 1,290.0 (β31-40) and 2,076.1 (β41-59). On electrospray ionization MS, the IDA patients had significantly elevated glutathionyl hemoglobin (GSHb) compared with the controls (16.9 ± 9.6 vs. 7.7 ± 3.7%; p = 0.002). GSHb levels correlated inversely with serum ferritin (Spearman rho -0.485; p = 0.003) and positively with serum transferrin receptor (0.460; p = 0.002). GSHb also demonstrated inverse correlations with hemoglobin (-0.512; p = 0.001), mean cell volume (-0.419; p = 0.026), serum iron (-0.446; p = 0.008) and transferrin saturation (-0.460; p = 0.008). For the first time, we show that GSHb is elevated in patients with IDA and has potential as a biomarker of this form of anemia.

Abstract
BACKGROUND F. hepatica infection is rare and mostly subclinical. Migration of juvenile forms of F. hepatica into the host's liver is accompanied by an inflammatory reaction followed by fibrosis and cirrhosis. OBJECTIVE The aim of this study was to evaluate oxidative status by using a novel automated method in patients with Fasciola hepatica. METHODS Twenty two patients with a diagnosis of F. hepatica and 26 healthy volunteers were enrolled in the study. Their Total antioxidant capacity status (TAC), total oxidant status (TOS) and catalase were measured in them and oxidative stress index (OSI) was calculated. These measurements were also taken for the control group and the values were compared. RESULTS Plasma levels of total TOS and OSI were significantly increased in patients as compared with healthy controls (P<0.001, P<0.001, P=0.001, P=0.008) respectively. In contrast, TAC level was significantly lower in patients as compared with controls (p<0.05). There was no significant difference between the catalase results of the two groups (p>0.05). CONCLUSION Total oxidative status and OSI were increased and total antioxidative status capacity was decreased in patients with F. hepatica infection. A high oxidative stress occurs during F. hepatica infection, which may cause severe damage in both the liver.

Abstract
BACKGROUND Oxidative stress has been implicated in over 100 disorders in recent years; however, the situation in restless legs syndrome (RLS) has not been studied yet. METHODS Fifty patients with RLS not medicated for RLS and 50 sex- and age-matched, healthy controls and controls with no pathology except mild iron deficiency or iron deficiency anaemia were enrolled. Patients with secondary RLS other than iron deficiency were excluded. Total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), arylesterase (ARE), paraoxonase (PON), stimulated paraoxonase (stim-PON), lipid hydroperoxides (LOOHs), acetyl cholinesterase (AChE) and butyryl cholinesterase (BuChE) were measured. Heart rate variability (HRV) analysis was performed. RESULTS TOS, ARE and AChE were increased (P = 0·018, P < 0·001 and P < 0·001, respectively), whereas LOOHs were decreased (P < 0·001) in RLS group. TAS, OSI, PON and stim-PON were comparable. Erythrocyte sedimentation rate (ESR) and mean platelet volume (MPV) were increased (P = 0·021 and P = 0·037, respectively) in RLS group. HRV triangular index (HRVi) was lower (P = 0·012) in RLS group. Other HRV parameters were similar. CONCLUSIONS Increased AChE and decreased LOOHs, which were influenced by increased PON1, were considered as indicators of efforts towards the protection of dopaminergic activity in central nervous system in RLS group. Increased ESR, MPV and low HRVi indicate elevated sympathetic activity in RLS group. Elevated sympathetic activity might be beneficial in relieving RLS symptoms, also causing increases in TOS. The evidence we found regarding oxidative stress and autonomic nervous system might be seminal in RLS treatment.

Abstract
BACKGROUND Paraoxonase-1 (PON1) is an esterase associated with the high-density lipoprotein (HDL) in serum. To date, there have been few reports about circulating PON1 protein concentration and specific activity in subjects with metabolic syndrome (MetS). More importantly, it is unknown whether weight loss could alter PON1 protein expression or specific activity in obese non-diabetic men with MetS. METHODS We prospectively enrolled a total of 40 obese non-diabetic men with MetS. Among them, 22 subjects finished the 3-month course of weight loss program and complied for longer follow-ups post-weight loss at the 3rd, 12th, and 18th month from the beginning of the program. Twenty-six healthy volunteers served as controls. Serum circulating PON1 concentration was measured by an enzyme linked immunosorbent kit (ELISA) and PON1 activity was measured by an automated PON1 activity assay. RESULTS Obese non-diabetic men with MetS (n=40) had a higher PON1 protein concentration (31.0 ± 11.3 vs. 24.8 ± 9.7 μg/ml, p=0.025) but lower specific enzyme activity (7.5 ± 4.0 vs. 11.2 ± 7.2 mU/μg, p=0.023) than those of the controls. Multivariate regression analysis of baseline PON1 specific activity revealed that adiponectin was a significant positive predictor (p=0.044) while monocyte chemotactic protein-1 (MCP-1) was a negative predictor (p=0.031). After a 3-month weight loss program, obese MetS men (n=22) had a significant weight reduction (95.8 ± 9.0 to 86.3 ± 10.4 kg, with a 9.9 ± 5.4% decrease, p<0.001). PON1 protein decreased significantly after weight loss and kept declining through the 3rd month till the 18th month follow-up. PON1 specific enzyme activity (baseline 7.5 ± 2.6 mU/μg) increased significantly after weight loss and kept increasing through the 12th month till the 18th month follow-ups (11.8 ± 6.4 mU/μg, p=0.001 vs. baseline). CONCLUSIONS Weight loss by a 3-month diet and exercise program time-sequentially increased PON1 specific enzyme activity in obese non-diabetic men with MetS.

Abstract
The present study was aimed to determine the effect of iron supplementation on levels of soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) in patients with iron deficiency anemia (IDA). In this study, 26 female patients diagnosed with iron deficiency were treated approximately 3 months of oral iron supplementation (99 ± 10 days; ferrous glycine sulfate; 100 mg/day of elemental iron). Levels of sICAM-1 and sVCAM-1 were assessed prior to treatment and after approximately 3 months of treatment and compared with 26 healthy female subjects. A significant increase in sVCAM levels was found in the patients with iron deficiency at the end of the treatment relative to pretreatment levels compared to controls, whereas no significant differences were determined in sICAM levels. In the posttreatment period, no significant change was observed in sICAM levels compared to the pretreatment levels, whereas sVCAM levels decreased. However, after the treatment period, the sVCAM, hemoglobin, mean corpuscular volume (MCV), and serum ferritin levels did not return to the normal range compared to the controls. Pretreatment sVCAM-1 levels were inversely correlated with levels of hemoglobin, hemotocrit, MCV, serum iron, and ferritin. After treatment, the sVCAM-1 levels were negatively correlated with ferritin levels. Levels of sVCAM were significantly higher in patients with IDA than controls. After the treatment period, the sVCAM levels were not completely normalized in patients with IDA compared to controls, regardless of the presence of inadequate levels of hemoglobin, MCV, and serum ferritin. Thus, iron supplementation not only ameliorates anemia, but may also reduce the inflammation markers in cases with IDA.

Abstract
OBJECTIVE The aim of this study was to evaluate how conditions that precede anaemia (iron store depletion and iron-deficient erythropoiesis) affect human serum paraoxonase PON1 activity. DESIGN AND METHODS Based on haemoglobin, transferrin saturation and serum ferritin values 119 athletes were divided into three groups: with iron depletion, with deficient erythropoiesis and controls. The following parameters were measured: paraoxonase activity towards paraoxon (POase) and diazoxon (DZOase), lipid hydroperoxides (LOOH), the pro-oxidant-antioxidant balance (PAB), red blood cells (RBC) and lipid status. RESULTS Significant differences were found between athletes with different stages of iron deficiency and controls with respect to PON 1 activity and oxidative stress status parameters (Wilks' Lambda=0.712, F=5.241, p<0.001, η(2)=0.156). There was no significant difference between the PON1 192 Q and R polymorphism distribution in the two groups of athletes with different stages of iron deficiency and controls (χ(2)=1.086; p=0.896). PON1 activity was positively correlated with RBCs, haemoglobin, transferrin saturation (p<0.001) and ferritin (p=0.037) and negatively correlated with LOOH (p=0.044) in all three study groups. CONCLUSIONS Deficient erythropoiesis in athletes contributes to impaired PON1 activity. In contrast, iron depletion, regardless of increased oxidative stress, does not affect PON1 activity.

Abstract
INTRODUCTION Laparoscopic cholecystectomy is the gold standard for the treatment of gallstone disease; however, adverse hemodynamic changes induced by increased intraabdominal pressure due to pneumoperitoneum are known to occur. Herein, we investigated the effects of pneumoperitoneum on oxidative stress markers, including paraoxonase, arylesterase, total oxidant status, and total antioxidant status, during laparoscopic cholecystectomy. PATIENTS AND METHODS Patients that underwent a laparoscopic cholecystectomy were classified as Group I, whereas patients that underwent surgical procedures for an abdominal wall hernia under general anesthesia were classified as Group II. Blood samples were obtained during the preoperative period, the perioperative period, and 24 hours after surgery (postoperative day 1). Leukocyte counts, neutrophil rates, paraoxonase activities, arylesterase activities, and total oxidant and antioxidant status levels were measured. RESULTS The differences in leukocyte counts and neutrophil rates were not significant between the two groups. In Group I, no significant differences in the total oxidant and antioxidant status levels were identified; however, paraoxonase and arylesterase levels were lower on postoperative day 1. No significant changes were observed in the total oxidant status, total antioxidant status, and paraoxonase or arylesterase activities in Group II. The perioperative total antioxidant status and arylesterase level were higher in Group I in comparison to Group II. CONCLUSION Paraoxonase and arylesterase levels are useful markers in the evaluation of oxidative stress caused by intraabdominal pressure due to pneumoperitoneum.

Abstract
OBJECTIVES The aim of this study was to investigate the activities of serum paraoxonase and arylesterase in patients with ankylosing spondylitis with respect to those of healthy controls, to assess whether these enzyme levels are related to disease activity and functional capacity. METHODS The study included 32 patients with ankylosing spondylitis whose diagnoses were made according to the modified New York criteria as well as 25 healthy controls matched for age and sex. The Bath Ankylosing Spondylitis Disease Activity Index and the Bath Ankylosing Spondylitis Functional Index were applied to the ankylosing spondylitis patients. As laboratory parameters, the erythrocyte sedimentation rate and serum C-reactive protein level were measured in patients and control subjects. Paraoxonase and arylesterase enzyme activities were measured using appropriate methods. RESULTS No statistically significant differences (p>0.05) were found between the ankylosing spondylitis patients and controls in terms of serum paraoxonase or arylesterase levels. Furthermore, there was no correlation between clinical and laboratory parameters in patients with ankylosing spondylitis. CONCLUSION Serum paraoxonase and arylesterase levels in ankylosing spondylitis patients may not differ from those of healthy controls, and there is no significant correlation between antioxidant parameters and the Bath Ankylosing Spondylitis Disease Activity Index or Bath Ankylosing Spondylitis Functional Index scores in ankylosing spondylitis patients. Further research is needed to provide deeper understanding of this disease.

Abstract
BACKGROUND Paraoxonase 1 (PON1) is an extracellular enzyme, which in the gastrointestinal tract may act as a local detoxifier, antioxidant, immunomodulator, and/or quorum-quenching factor. There are no data on PON1 activity in Crohn's disease (CD). METHODS PON1 phenotype and activity were determined spectrophotometrically in 52 subjects with CD, 67 with ulcerative colitis (UC), and 99 healthy individuals, and related to lipid peroxidation and disease phenotype, clinical and biochemical activity, and therapeutic strategy. Diagnostic utility of PON1 was evaluated by ROC analysis and compared with C-reactive protein (CRP). RESULTS In comparison with controls (166 U), PON1 was reduced only in active CD (110 U, P < 0.0001) and UC (126 U, P < 0.0001), and correlated with disease activity (r = -0.47, P = 0.001 in CD and r = -0.50, P < 0.001 in UC). PON1 significantly correlated with erythrocyte sedimentation rate (ESR) (r = -0.36), platelets (r = -0.35), interleukin-6 (r = -0.45), hemoglobin (r = 0.29), transferrin (r = 0.46), albumin (r = 0.60) in CD, and CRP (r = -0.29), ESR (r = -0.37), platelets (r = -0.43), leukocytes (r = -0.50), interleukin-6 (r = -0.45), hemoglobin (r = 0.34), transferrin (r = 0.54), and albumin (r = 0.50) in UC. PON1 correlated positively with lipids but not with their peroxidation markers (thiobarbituric acid-reactive substances, lipid hydroperoxides, ox-LDL, and ox-LDL autoantibodies). PON1 phenotype B (protective against IBD) tended to be less frequent in IBD patients than controls, and associated with lower concentration of inflammatory indices. PON1 was a poorer indicator of CD or UC than CRP. CONCLUSIONS PON1 was reduced in IBD, despite treatment with antioxidant 5'-aminosalicylate derivatives. PON1 reflected disease activity, inflammation severity, and anemia but not lipid peroxidation. The diagnostic power of PON1 was insufficient for its clinical application.

Abstract
OBJECTIVE The HDL-associated paraoxonase and arylesterase activities play a role in decreasing oxidative stress, which is known to contribute to cancer development. The aim of this study was to evaluate serum paraoxonase and arylesterase activities and lipid hydroperoxide (LOOH) levels in patients with newly-diagnosed epithelial ovarian cancer. MATERIALS Serum paraoxonase and arylesterase activities, total free sulfhydryl (-SH) levels and LOOH levels were measured in patients with epithelial ovarian cancer (n=24) and controls (n=29). RESULTS Serum paraoxonase activity and arylesterase activity, as well as -SH levels were significantly lower (p=0.003, p<0.001 and p<0.001, respectively) in patients with epithelial ovarian cancer compared to controls, while LOOH levels were significantly higher (p<0.001). A significant inverse correlation was found between the stage, grade and CA-125 level of ovarian cancer and paraoxonase activity (rho=-0.630, p=0.001 and rho=-0.601, p=0.002 and rho=-0.436, p=0.033, respectively), arylesterase activity (rho=-0.601, p=0.002 and rho=-0.713, p<0.001 and rho=-0.580, p=0.003, respectively), and -SH levels (rho=-0.642, p=0.001 and rho=-0.637, p=0.001 and rho=-0.530, p=0.008, respectively). In contrast, there was a positive correlation between LOOH and the stage, grade and CA-125 level of ovarian cancer (rho=0.565, p=0.004 and rho=0.479, p=0.018 and rho=0.642, p=0.001). CONCLUSION Our results suggest that diminished paraoxonase and arylesterase activity, -SH levels and increased LOOH levels are associated with particular stage, grade and CA-125 level of ovarian cancer.

Abstract
BACKGROUND No prospective studies have evaluated the effects of correction of iron deficiency anemia on insulin resistance in non-diabetic premenopausal women. We investigated this relationship in 54 non-diabetic premenopausal women with iron deficiency anemia. SUBJECTS AND METHODS All patients were treated with oral iron preparations. Insulin resistance was calculated with the Homeostasis Model Assessment formula. All patients were dichotomized by the median for age and BMI to assess how the relationship between iron deficiency anemia and insulin resistance was affected by age and BMI. RESULTS Although the fasting glucose levels did not change meaningfully, statistically significant decreases were found in fasting insulin levels following anemia treatment both in the younger age (<40 years) (P=0.040) women and in the low BMI (<27 kg/m2) (P=0.022) subgroups but not in the older age (>or=40 years) and the high BMI (>or=27 kg/m2) subgroups. Post-treatment fasting insulin levels were positively correlated both with BMI (r=0.386, P=0.004) and post-treatment hemoglobin levels (r=0.285, P=0.036). Regression analysis revealed that the factors affecting post-treatment insulin levels were BMI (P=0.001) and post-treatment hemoglobin levels (P=0.030). CONCLUSION Our results show that following the correction of iron deficiency anemia, insulin levels and HOMA scores decrease in younger and lean non-diabetic premenopausal women.

Abstract
The aging process is associated with an increasing prevalence of osteoporosis and atherosclerosis, but it is uncertain if these two conditions are interrelated. Serum paraoxonase-1 (PON1) is a high-density lipoprotein (HDL) associated enzyme that has been implicated in the pathogenesis of atherosclerosis. Our aims of the study were to investigate (1) serum paraoxonase and arylesterase activities and, lipid hydroperoxide (LOOH) levels in healthy postmenopausal women and (2) whether there were any associations between these enzyme activities and bone mineral density (BMD). A total of 97 generally healthy postmenopausal women were enrolled in the study. BMD was measured at lumbar spine (LS) and femoral neck (FN) with dual energy X-ray absorptiometry. Serum paraoxonase and arylesterase activities were measured spectrophotometrically. LOOH levels were measured by iodometric assay. In this population, 50 (51%) women had BMD T scores < -2.5 at the LS and/or FN defined as osteoporosis and 47 (49%) of them had normal BMDs. Serum paraoxonase, arylesterase, and LOOH activities were not significantly different between osteoporotic and nonosteoporotic postmenopausal women. There were also no correlations between paraoxonase, arylesterase, LOOH activities, and LS BMD and FN BMD. We conclude that there may be not good evidence to support a direct relationship between osteoporosis and atherosclerosis in these subjects. However, prospective studies with larger groups are needed to investigate this issue further.
