Aim: Ischemia modified albumin (IMA), sialic acid and malondialdehyde (MDA) are the most frequently used biomarker of oxidative stress in many health problems. In this study, it was aimed to investigate the relationship between IMA, sialic acid and MDA levels and visual analogue scale (VAS) pain scores in the cupping blood of the interscapular region in women with headache, low back pain, and backache. Materials and Methods: This study was performed on 96 women between the ages of 18-55. Participants were divided into three groups according to complaints of backache (30 women, group 1), low back pain (31 women, group 2) and headache (35 women, group 3). IMA, sialic acid and MDA levels were measured spectrophotometrically in the cupping blood of the interscapular region. Results: There was no significant difference between IMA, sialic acid and MDA levels in the cupping blood of the interscapular region of groups. There was a statistically significant positive correlation between MDA levels of group 1, group 2 and group 3 and VAS values (p <0.01). In addition, there was a statistically significant positive correlation between sialic acid levels and VAS values of group 1 and group 3 (p <0.01). In addition, statistically significant positive correlation was found between IMA levels and VAS values of group 3 (p <0.01). Conclusion: Our study was the first study in the literature investigating the MDA, IMA and sialic acid levels in the cupping blood in the differential diagnosis of different region pain types. The levels of these parameters were not found to be different in distinguishing different region etiologies of pain in the obtained findings. However, according to our VAS scores, there was a decrease the pain of the patients after cupping therapy and the relationship between these values and oxidative parameters was also determined.

Aim: This study aimed to investigate to usability of ischemia modified albumin (IMA) and IMA/albumin ratio (IMAR) values in the follow-up of ALF patients. King College criteria (KCC) and Model for End-Stage Liver Disease (MELD) score are the most commonly used criteria in the follow-up of patients with acute liver failure (ALF). However, these criteria cannot always predict prognosis and the need for liver transplantation (LT). Materials and Methods: IMA and IMAR values of 23 ALF patients and 43 healthy volunteers were measured. Then IMA and IMAR values were compared with KCC and MELD score to predict LT requirement and prognosis in ALF patients. Results: IMA and IMAR values were significantly higher in ALF patients compared healthy volunteers (p=0.001, p=0.001; respectively). IMA and IMAR values predicted LT requirement in ALF patients such as KCC and MELD (=30) score (p=0.006, p=0.04, p=0.001, p=0.03; respectively). IMA values were found to better than KCC in predicting mortality (p=0.008, p=0.02; respectively). MELD (=30) score failed to predict mortality (p=0.44). Conclusion: IMA and IMAR values can be used as diagnostic biomarkers in ALF patients. IMA is a better prognostic biomarker in the follow-up of ALF patients. [ABSTRACT FROM AUTHOR]

Aim: Seborrheic dermatitis (SD) is a commonly seen chronic inflammatory skin disease that occurs as scaly reddish-brown itchy patches on sebaceous, gland-rich areas of the scalp, face, and trunk. The relation between SD disease and serum IMA (Ischemia modified albumin) levels remains unknown. To investigate the potential role of serum IMA and corrected IMA levels in SD disease. Materials and Methods: Thirty-seven participants who were diagnosed with SD disease and sixty-two healthy subjects (control group) were enrolled in the study. Venous blood samples were collected from each participant, and serum IMA was measured spectrophotometrically using the albumin cobalt binding test. Results: The serum IMA and corrected IMA levels were statistically significant between the groups, and the levels of IMA and corrected IMA were measured as SD patients group 0.70, 0.70 and control group 0.52, 0.51 ABSU (absorbance units), respectively (p < 0.05). Moreover, serum IMA and corrected IMA levels were statistically significant between male and female groups in terms of gender as 0.75 and 0.69 ABSU, respectively (p < 0.05). Serum albumin levels, age, and BMI (body mass index) were statistically insignificant between these groups. Conclusion: Our results show increased serum IMA and corrected IMA levels in patients with SD. Evaluation of IMA and corrected IMA levels in SD disease may contribute to diagnosis and prognosis. Further and comprehensive studies are needed. [ABSTRACT FROM AUTHOR]

Aim: In the present study, we aimed to evaluate serum IMA, IMA/albumin ratio, and DTDH levels in patients with early- and late-onset PE compared to healthy controls. Impaired homeostasis between oxidant and antioxidant mechanisms, inflammatory processes, and endothelial dysfunction play a key role in the pathogenesis of preeclampsia (PE). Serum ischemia modified albumin (IMA) and dynamic thiol/disulfide homeostasis (DTDH) levels are elevated in the presence of inflammation, oxidative stress, and endothelial dysfunction. Material and Methods: A total of 24 patients with early-onset PE and 62 patients with late-onset PE were included. The control group consisted of 46 healthy controls with similar gestational weeks. Serum samples were collected and IMA, albumin, and native, total, and disulfide thiol levels analyzed. Corrected IMA/albumin ratios were also calculated. Results: Disulfide levels, disulfide/native and disulfide/total thiol levels were higher in patients with early-onset PE compared to lateonset patients(p=0.008, p=0.022, and p=0.021, respectively). However, there was no significant difference between the late-onset PE patients and late-onset PE controls. Although there was no significant difference in the IMA levels between the patient and control groups, the IMA/albumin ratio was higher in the early-onset and late-onset PE patients, compared to the control group. However, there was no significant difference between the early-onset and late-onset PE patients. Conclusion: Our study results showed increased disulfide levels, disulfide/native thiol, disulfide/total thiol and IMA/albumin ratio in the early-onset PE patients, indicating increased oxidative stress in the pathogenesis of PE. In the late-onset PE patients, there was an increase only in the IMA/albumin ratio. However, further large-scale, prospective studies are needed to confirm the diagnostic value of these markers in the clinical practice [ABSTRACT FROM AUTHOR]

Aim: The cardiovascular system is susceptible to thyroid hormones. Many studies show that hypothyroidism is associated with increased cardiovascular risk, functional abnormalities, atherosclerosis, and increased arterial stiffness. Pulse wave velocity (PWV) and augmentation index (AI) are regarded as indexes of arterial stiffness. Oxidative free radicals that occur during ischemic events cause certain chemical changes in the albumin molecules. The ischemia-modified albumin (IMA) has been suggested as an indicator of oxidative stress. Evaluation of oxidative stress markers and parameters of arterial stiffness can shed light on the mechanism of increased cardiovascular risk in patients with hypothyroidism. Material and Methods: For this study, PWV, AI measurements, and IMA levels of 20 untreated patients with overt hypothyroidism (OH), 21 untreated patients with subclinical hypothyroidism (SH), and 30 healthy controls (control-CNT) were evaluated. Patients and the healthy controls' gender, age, weight, height, body mass index, waist circumference, smoking habit and blood biochemical results were recorded. Results: PWV was found to be increased in patients with overt hypothyroidism; however, there was no difference in between subclinical hypothyroidism and control group(p=0,881). Also, PWV had a significant positive correlation with; age, BMI, waist circumference, blood glucose, uric acid, pulse pressure and systolic and diastolic blood pressures. IMA levels were not different in between the groups. Conclusion: Hence the increased CV risk in patients with hypothyroidism is a multifactorial state; the interplay of many factors determines it. Future studies with larger sample sizes are needed to evaluate the possible relationship among IMA levels, arterial stiffness parameters and cardiovascular risk factors in patients with hypothyroidism.

Aim: "Ischemia modified albumin" (IMA) was investigated as a possible biomarker in several diseases such as vascular disorders. We aimed to reveal the possible value of IMA in predicting the development of contrast induced nephropathy (CIN) after coronary angiography in patients with stable angina pectoris. Material and Methods: 106 patients underwent coronary angiography with a diagnosis of stable angina pectoris were included in our study. Basic demographic and clinical findings and laboratory values were recorded and analyzed. Serum creatinine (SCre) levels were also measured 48 hours after coronary angiography and recorded. Amount of contrast agent (CA) given during coronary angiography was recorded. The patients were divided into 2 groups: CIN positive and CIN negative groups. Results: CIN was developed in 14 patients (13%); and IMA levels were similar in CIN positive and negative groups (p>0.05). SCre (both measurements before and after CA administration) was not correlated with IMA levels. There was no association between drug usage and development of CIN (p>0.05). Comorbidities were not associated with the development of CIN (p>0.05) with the exception of hypertension (HT). Presence of hypertension (p=0.0393) and female gender (p=0.0199) was associated with development of CIN. Mean age was 61.3 and 52.3 in CIN positive and negative groups, respectively (p>0.05). Conclusion: Any specific biomarker indicating CIN is not available yet. Most frequently used marker is the measurement of SCre 24-48 hours after administration of CA. We found IMA levels not to be a predictor for the development of CIN. Further investigations will clearly determine the importance of IMA as a biomarker in renal failure developed after CA administration. [ABSTRACT FROM AUTHOR]
