    (Academic journal of health science, 2023) Ijeoma Leticia Okoroiwu; Emmanuel Ifeanyi Obeagu; Hilda González San; Miguel Sebastiana Arroyo Bote; Getrude Uzoma Obeagu
    Background: The association between HLA-DR antigen and diabetes mellitus was studied in know diabetic patient on medication at University of Nigeria Teaching Hospital Enugu. The study was done to characterize the HLA-DR antigen in patients with type 1 diabetes mellitus attending University of Nigeria Teaching Hospital, Enugu. Materials and methods: Ethical clearance was obtained from the Hospital Research Ethics Committee, while informed consent was obtained from each member of the studied group. Whole blood was collected from each subject using standard venipuncture into an EDTA anticoagulant bottle and fluoride tube. The fasting glucose level was determined by enzymatic oxidase-peroxidase method and glycated hemoglobin (HbAlc) spectrophotometrically. The HLA-DR antigen alleles were studied using sequence specific primer polymerase chain reaction (SSP-PCR) techniques. Results: The mean results of glucose and HbAlc levels were normal and showed no significant difference when they were compared according to their alleles. The correlation using Kruskal-Wallis test and Dunn’s Multiple comparison test showed no significant difference in all the group; HbAlcvs HLA-DR antigens and glucose levels vs HLA-DR antigens P = 0.7325 and P = 0.6081. However, the alleles HLA- DRB4*01 (17.5%), DRB1* 03 (29.2%) and DRB1*15 (35%) showed higher frequencies in the group studied.

    Evaluation Release of Cytokines (Il-6, Il-8, Tnf) Levels in Stored Whole Blood
    (International Journal of Innovative and Applied Research, 2022) Ijeoma Leticia Okoroiwu; Emmanuel Ifeanyi Obeagu
    Family planning can help reduce maternal mortality by reducing the number of pregnancies, the number of abortions, and the proportion of births at high risk in Bushenyi District. It has been This study was done to determine the release of cytokines (IL-6, IL-8 and TNF) in stored whole blood. Fifty (50) samples were collected from 50 subjects for the study. These comprise of 25 males and 25 females. The subjects comprise of adults aged 18-40 years with 29 years as the mean age. The study was conducted at GEM Research Laboratories. The IL-6, IL-8 and TNF were assayed respectively for all subjects on 0 day, 14th day and 35th day. The mean levels of IL-6, IL-8, and TNF were 10.68 pg/ml, 3.40 pg/ml, and 1.43 pg/ml respectively for 0 day, 7.56 pg/ml, 16.52 pg/ml, and 7.88 pg/ml respectively for 14th day, and 5.12 pg/ml, 124.24 pg/ml, and 59.08 pg/ml respectively for 35th day. Significant statistical difference (p<0.05) was observed in IL-6 and IL-8 mean levels across all groups (0/14th day, 0/35th and 14th/35th day) compared except in 0/14th where TNF mean levels showed no significant statistical difference (p>0.05). We recommend pre storage white cell reduction for whole blood and all red cell components.

    Evaluations of Serum Electrolytes Levels in Kidney Failure Subjects Undergoing Dialysis in Owerri
    (International Journal of Innovative and Applied Research, 2022) Ijeoma Leticia Okoroiwu; Emmanuel Ifeanyi Obeagu
    This study was carried out to determine serum electrolytes levels in kidney failure subjects undergoing dialysis in Owerri. Sixty (60) subjects between the age of eighteen and seventy years were selected for the study. Sodium & Potassium were determined by Emission Flame Photometry and Chloride was determined by Mercuric Nitrate method. The test was calculated statistically to get the means. P<0.05 was considered statistically significant while P>0.05 was considered not statistically significant. The levels of these ions were correlated. Sodium ion concentration was statistically and significantly decreased (p=0.001) in kidney failure subjects undergoing dialysis when compared with the control subjects. There was statistical significant difference (p=0.000) in the mean value of potassium ion concentration in kidney failure subjects undergoing dialysis when compared with the control subjects. There was statistical significant difference (p=0.001) in the mean value of chloride ion concentration in kidney failure subjects undergoing dialysis when compared with the control subjects. There was statistical significant difference (p=0.000) in the mean value of bicarbonate ion in kidney failure subjects undergoing dialysis when compared with the control subjects. There was a significant negative correlation of sodium ion with potassium and bicarbonate ion (r= -0.107, p=0.000; r=-0.192, p=0.000 respectively which indicates an increase in sodium with decrease in potassium and bicarbonate. There was a significant positive correlation of sodium ion with chloride ion (r=-0.185, p=0.000) which indicates increase in sodium leading to increase in chloride. There was a significant negative correlation of potassium ion with chloride (r= -0.130, p=0.000) which indicates increase in potassium leading to a decrease in chloride. There was a significant positive correlation of potassium ion with bicarbonate ion (r=-0.760, p=0.000) which indicates increase in potassium leading to increase in bicarbonate. There was significantly no correlation between chloride ion with bicarbonate ion (r=-0, p=0.000). Sodium, Chloride and Bicarbonate ion concentrations were statistically and significantly increased in kidney failure subjects undergoing dialysis when compared with the control subjects indicating hypernatremia and hyperchloremia and alkalosis respectively while Potassium ion concentrations was decreased indicating hypokalemia. The use of dialysis is effective in balancing the levels of these ions that were abnormally low and high respectively in Kidney failure subjects.
