The Significance of Albumin Concentration and some of its Altered Forms in Iraqi Patients with Chronic Hepatitis B Virus

Abstract

Background: The liver synthesizes albumin, a pivotal protein with approximately 60-65% of total plasma proteins. During ischemic attacks linked to oxidative stress, reactive oxygen species, and acidosis, the properties of albumin undergo alterations. This leads to generation of ischemia-modified albumin, which is characterized by a diminished metal-binding capacity, particularly for transition metals like copper, nickel, and cobalt. Objectives: This study aimed to assess the significance of serum albumin and ischemia-modified albumin concentrations in Iraqi individuals with hepatitis B virus Methods: A case control study consisted of 50 patients with hepatitis B were recruited from Gastroenterology hospital in the Medical city/ Baghdad/ Iraq, during the period January to February in 2023, The patients group included males and females; whose ages ranged from 18 years to 77 years with a mean value 44 year. Meanwhile the study group consisted of 50 age- and sex-matched normal healthy individuals. Albumin concentration was determined in the serum samples, using a Biosystems kit, and ischemia modified albumin concentration were measured through the albumin cobalt binding test. The ischemia modified albumin/ [albumin] ratio and Ischemia modified albumin index were then calculated. Statistical Analysis: results were reported as a mean value ± standard deviation. The differences were considered highly significant if (p < (0.001), and significant where (p = (0.002) and (p = (0.033) Results: lower serum albumin concentration was measured in the patients group, while the mean value of ischemia modified albumin concentration in the patients' group and healthy control were 0.466 ± 0.114 absorbance unit & 0.395 ± 0.070 absorbance unit, respectively, with a statistically significant increase (P < 0.001). The ischemia modified albumin ratio in the hepatitis B patients and control groups were 0.172 ± 0.073 and 0.117 ± 0.050, respectively, showing a significant increase as well (P < 0.001). Additionally, the ischemia modified albumin index in the patients and the control groups were 0.491 ± 0.167 & 0.390 ± 0.131, respectively, with a statically significant increase (p<0.001) in the patients group. Conclusion: In the patients’ group with hepatitis B, serum albumin concentration is decreased, while the level of ischemia modified albumin, ischemia modified albumin ratio, and ischemia modified albumin index are increased. The elevation in ischemia modified albumin, ischemia modified albumin ratio, and ischemia modified albumin index were more prominent in younger patients and those with albumin concentration less than 4g/dl. Moreover, the prevalence of hepatitis B is higher in men compared to women.
