Abstract
AIM The differential diagnosis of paediatric patients admitted to the emergency department presenting with acute abdominal pain may be difficult. This study aims to investigate the diagnostic value of ischaemia-modified albumin (IMA) in the differential diagnosis of acute abdominal pain in children and in distinguishing surgical from non-surgical cases. METHODS The study was conducted with a total of 152 subjects who provided informed consent, including 112 patients admitted to the paediatric emergency department and paediatric surgical clinic and 40 healthy control subjects. Blood samples were collected after initial examination to determine IMA, white blood cell (WBC) and C-reactive protein (CRP) values. RESULTS Mean IMA values of patients with acute appendicitis (AA), perforated appendicitis (PA) and non-specific abdominal pain were significantly higher compared to the control group. Mean IMA values of the AA and PA cases were also significantly higher compared to the group with non-specific abdominal pain. No significant difference was determined in mean IMA between the AA and PA groups. WBC and CRP levels of the AA and PA groups were significantly higher compared to the group with non-specific abdominal pain. CONCLUSION Our study shows that IMA, together with WBC and CRP, may be a biomarker capable of assisting the differential diagnosis of acute abdominal pain in children and distinguishing surgical from non-surgical cases.

Abstract
Purpose. To investigate the oxidant and antioxidant status of patients with type 2 diabetes mellitus and nonproliferative diabetic retinopathy (DRP). Methods. Forty-four patients who had cataract surgery were enrolled in the study. We included 22 patients with DRP in one group and 22 patients in the control group. Samples of aqueous humor and serum were taken from all patients. Serum and aqueous ischemia-modified albumin (IMA), total thiol, total antioxidant capacity (TAC), and total oxidative stress (TOS) levels were compared in two groups. Results. Median serum IMA levels were 44.80 absorbance units in the DRP group and 40.15 absorbance units in the control group (P = 0.031). Median serum total thiol levels in the DRP group were significantly less than those in the control group (3051.13 and 3910.12, resp., P = 0.004). Mean TOS levels in the serum were 2.93 ± 0.19 in the DRP group and 2.61 ± 0.26 in the control group (P = 0.039). The differences in mean total thiol, TAC, and TOS levels in the aqueous humor and mean TAC levels in the serum were not statistically significant. Conclusion. IMA, total thiol, and TOS levels in the serum might be useful markers in monitoring the risk of DRP development.

Abstract
Background Ischemia-modified albumin is an altered serum albumin that forms under conditions of oxidative stress, a state also associated with doxorubicin-induced myocardial injury. Objective The aim of this study was to better assess diagnostic and prognostic significance of ischemia-modified albumin in patients with breast cancer undergoing doxorubicin chemotherapy. Methods Blood samples were collected from 152 breast cancer patients before and after each cycle of doxorubicin chemotherapy to measure the serum levels of ischemia-modified albumin, cardiac troponin T and creatine kinase-MB. We also monitored cardiac function during a 12 month follow-up. Results There was a significant difference in ischemia-modified albumin levels before and after each cycle of chemotherapy and the ischemia-modified albumin concentration positively correlated with the cumulative dose of doxorubicin (r = 0.212, P < 0.05). The combination of ischemia-modified albumin with cardiac troponin T and creatine kinase-MB increased the sensitivity to 0.920 and the specificity to 0.830 in the diagnosis of doxorubicin-induced myocardial injury. The optimal cutoff for ischemia-modified albumin concentration was 112.09 U/ml. The rate of change for ischemia-modified albumin levels correlated negatively with the rate of change for left ventricular ejection fraction at one year (r = –0.221, P < 0.05). Conclusion Ischemia-modified albumin may be a clinically potential new marker for diagnosing doxorubicin-induced myocardial injury, and is helpful to predict long-term impairment of cardiac function.

Abstract
OBJECTIVE To investigate whether ischemia-modified albumin (IMA) is reliable for early diagnosing symptomatic lacunar infarction (SLI) in type 2 diabetics. DESIGN AND METHODS Ninety-seven consecutive diabetic patients, 47 with SLI, and 45 healthy controls were enrolled. Serum IMA and plasma total homocysteine (tHcy) were measured on an autoanalyzer and evaluated in distinguishing SLI. RESULTS Serum IMA levels were 97.35 ± 5.25 U/L in the healthy control group, 103.26 ± 7.43 U/L in the non-SLI group, and 139.84 ± 20.00 U/L in the SLI group. Plasma tHcy levels were 8.08 ± 1.82 μmol/L, 11.31 ± 3.03 μmol/L, and 13.10 ± 3.67 μmol/L, respectively. The differences in IMA and tHcy levels were statistically significant for all groups (p<0.05). Receiver operating characteristic curve analyses revealed the areas under curve were 0.866 for IMA and 0.352 for tHcy. CONCLUSION This study indicates that IMA was significantly elevated in the acute phase of SLI and more sensitive than tHcy in distinguishing SLI.

Abstract
Cardiac biomarkers have well-established roles in acute coronary syndrome and congestive heart failure. In many instances, the detection of cardiac biomarkers may aid in the diagnosis and risk assessment of critically ill patients. Despite increasing interest in the use of cardiac biomarkers in noncardiac critical illness, no clear consensus exists on how and in which settings markers should be measured. This article briefly describes what constitutes an ideal biomarker and focuses on those that have been most well studied in critical illness, specifically troponin, the natriuretic peptides, and heart-type fatty acid-binding protein.

Abstract
PURPOSE To establish the correlation between ischemia-modified albumin (IMA) and malondialdehyde (MDA) and the development of diabetic retinopathy (DRP) in patients with diabetes mellitus. METHODS Seventy Type 2 diabetic patients, 35 with DRP, and 36 healthy controls were enrolled in this study. Serum IMA and MDA levels were compared statistically. Receiver operating characteristic curve analysis was also performed to calculate the value of IMA and MDA in distinguishing DRP. RESULTS Mean serum IMA levels were 0.658 ± 0.128 absorbance units in the non-DRP group, compared with 0.767 ± 0.074 absorbance units in the DRP group and 0.619 ± 0.044 absorbance units in the control group. Mean serum MDA levels were 0.325 ± 0.172 nmol/mL, 0.244 ± 0.152 nmol/mL, and 0.178 ± 0.131 nmol/mL, respectively. The differences in IMA and MDA levels were statistically significant for all groups (P < 0.05 for all). The areas under the receiver operating characteristic curves for the determination of DRP in diabetic patients were 0.789 (95% confidence interval, 0.682-0.896) for IMA and 0.3 (95% confidence interval, 0.175-0.426) for MDA. CONCLUSION Both serum IMA and serum MDA levels were higher in the diabetic patients compared with the control group. In particular, the high sensitivity of IMA toward DRP showed that it reflected retinal vascular complication better than MDA. Ischemia-modified albumin may be a useful marker in monitoring the risk of DRP development.

Abstract
OBJECTIVES Previous studies have demonstrated that ischemia-modified albumin (IMA) is a useful marker for the diagnosis of ischemic events. This study aimed to determine the value of ischemia-modified plasma albumin in the early diagnosis of acute mesenteric ischemia in an experimental model. METHODS The study was performed on 32 Wistar albino rats divided into control (n = 8), sham (n = 8), 2-hour (n = 8), and 6-hour (n = 8) ischemia groups. Mesenteric ischemia was created by arterial occlusion, and then blood samples (2 mL) were collected and centrifuged. Serum levels of IMA were measured by a rapid calorimetric test that determined the reduced cobalt binding to albumin. For histopathologic evaluation, samples of the small intestine were obtained from the animals after they were euthanized at the end of the experiment. RESULTS Histopathologic damage of the intestinal wall correlated with the duration of ischemia. While the mean pathology scores of the 2- and 6-hour ischemia groups were different from each other, IMA levels (mean ± SD) in the four groups were not significantly different from each other: 0.55 ± 0.07 absorbance units (ABSU) in the control group, 0.62 ± 0.09 ABSU in the sham group, 0.60 ± 0.07 ABSU in the 2-hour ischemia group, and 0.64 ± 0.12 ABSU in the 6-hour ischemia group (p = 0.153). CONCLUSIONS Serum IMA values were not useful in the early diagnosis of acute mesenteric ischemia. Further studies to investigate ischemic and nonischemic conditions that affect IMA levels are needed.

Abstract
Background Ischaemia-modified albumin (IMA) is a relatively new marker of ischaemia. IMA has not been studied previously in pleural effusions due to congestive heart failure (CHF). The aim of our study was to assess the diagnostic value of IMA in the pleural fluid (PF) and serum for the identification of pleural effusion due to CHF. Methods The concentrations of pleural fluid and serum IMA were measured in a total of 40 patients: 10 with CHF and 30 with non-cardiac failure (10 with acute pulmonary embolism, 10 with parapneumonic effusion and 10 with malignancy). The area under the curve (AUC) quantified the overall diagnostic accuracy of the tests. Results The study demonstrated that IMA concentration was higher in both pleural fluid and serum of CHF patients compared with non-cardiac patients. PF and serum IMA demonstrated AUCs of 0.927 (95% CI: 0.844–1.00, P < 0.001), and 0.792 (95% CI: 0.653–0.930, P = 0.006), respectively, for diagnosing effusions due to CHF. The sensitivity and specificity of PF-IMA for CHF at the cut-off concentration of ≥1.0 absorbance units was 90% and 80%, respectively. Its negative predictive value (NPV) was quite high (96%). Positive correlation was found between PF-IMA concentrations and serum-IMA ( r = 0.540, P < 0.001). Conclusions Measuring IMA concentrations in serum and pleural fluid may be helpful in distinguishing pleural effusion due to a cardiac or non-cardiac aetiology.

Abstract
OBJECTIVES This experimental study aimed to assess the changes in the levels of serum ischemia-modified albumin (IMA) and interleukin-6 (IL-6) by time in cases of acute mesenteric ischemia due to superior mesenteric artery occlusion. METHODS Twenty-one New Zealand rabbits were randomly divided into three groups. Blood samples were collected at hours 0, 1, 3, and 6 from animals in a control group; a sham group following a simple laparotomy; and in an ischemia group following superior mesenteric artery ligation. All blood samples were analyzed for serum IMA and IL-6 levels, and then the time-dependent changes of biomarkers were investigated. RESULTS The serum IMA levels of the ischemia group at hours 3 and 6 were significantly higher than those of the control and sham groups (hour 3, p = 0.017; hour 6, p = 0.001). The increase in serum IL-6 levels in the ischemia group at hours 1, 3, and 6 compared to the control and sham groups was also significant (hour 1, p = 0.002; hour 3, p = 0.003; hour 6, p = 0.003). CONCLUSIONS IMA may be helpful as a marker in the diagnosis of acute mesenteric ischemia; however, its diagnostic value and use as a routine biochemical test should be assessed in further studies.

Abstract
OBJECTIVES Ischemia-modified albumin (IMA) is an emerging diagnostic biomarker for many ischemic conditions. This study was conducted to investigate whether there is a change in IMA levels in carbon monoxide (CO) poisoning and, if so, the clinical relevance of IMA levels. METHODS This cohort study, performed between November 2008 and April 2009, compared the serum IMA levels of 33 CO-poisoned patients taken at the time of presentation at the emergency department and after 3 hours of treatment and 49 healthy controls. In addition, IMA and carboxyhemoglobin levels were analyzed according to CO poisoning patients' poisoning severity scores. RESULTS Carbon monoxide patients' IMA levels were higher than those of the control group both at time of admission and at the third hour of the treatment, P < .0001. A significant fall was determined in carboxyhemoglobin (CO-Hb) levels at the end of the third hour of treatment, P < .0001. However, there was no significant difference between the IMA levels measured at admission and at the end of the third hour of treatment (P > .05). There was no significant correlation between IMA and CO-Hb levels in CO-poisoned patients. Also, there was no difference in blood IMA levels in classification according to patients' poisoning severity score and CO-Hb levels. CONCLUSION Results from this pioneering study established a high level of IMA in CO-poisoned patients, suggesting that IMA may also be sensitive to hypoxia. Considering the preliminary nature of this study, the clinical utility of IMA levels in CO poisoning should be further investigated with more comprehensive studies.

Abstract
Serum biomarkers related to the cascade of inflammatory, hemostatic, glial and neuronal perturbations have been identifed to diagnose and characterize intracerebral hemorrhage and cerebral ischemia. Interpretation of most markers is confounded by their latent rise, blood-brain barrier effects, the heterogeneity of etiologies and the wide range of normal values, limiting their application for early diagnosis, lesion size estimation and long-term outcome prediction. Certain hemostatic and inflammatory constituents have been found to predict response to thrombolysis and worsening due to infarct progression and secondary hemorrhage, offering a potential role for improved treatment selection and individualization of therapy. Biomarkers will become increasingly relevant for developing targets for neuroprotective therapies, monitoring response to treatment and as surrogate end points for treatment trials.
