      Abstract: This study was designed to determine the seroprevalence of Cytomegalovirus (CMV) among blood donors at Bowen University Teaching Hospital (BUTH), Ogbomoso, Oyo State, Nigeria. Three hundred (300) consenting potential blood donors were recruited between April and September, 2012 into the study. Each subject was screened for HIV, HBsAg and HCV and structured questionnaire was administered. A total of 93(male = 63; Female = 30) subjects with mean age of 45±2.3 years previously tested negative to HIV, HBsAg and HCV were screened for CMV using Enzyme Linked Immunosorbent Assay (ELISA). Twenty-six (28.0%) were positive for anti-CMV IgM and Twenty-four (25.8%) were positive for anti- CMV IgG. The prevalence of anti- CMV IgM was highest in the age range 18-24 (45.5%), female (43.3%), single (31.4%), student (37.8%), and donors who have not been transfused (27.8%). The prevalence of anti- CMV IgG was highest in the age range 18-24 (39.4%), female (35.1%), single (25.5%), student (35.1%), and donors who have not been transfused (25.6%). The IgG+IgM- has a mean value of 3.0 which is significantly different from that of IgG-IgM+ antibody with a mean value of 5.0 These results provide more and further evidence that cytomegalovirus is present among blood donors at BUTH, and that immunocompromised individual that has been transfused with the infected blood or blood products are at risk of been infected with the virus. This also confirms that the virus spreads through blood transfusion.

  • Association of Adipocytokines: Resistin and Retinol Binding Protein-4 with
           Severity of Preeclampsia and Insulin Resistance

      Abstract: Dysregulation of maternal circulating adipocytokines has been implicated in several obstetrical syndromes including preeclampsia (PE). It has been suggested that adipocytokines provide a molecular link between metabolic derangements and inflammatory response in complicated pregnancies. We aimed in this study to evaluate the relationship between serum levels of Retinol binding protein-4 (RBP-4) and Resistin with clinical, anthropometric and metabolic parameters of PE. This study included 3 groups: group 1 included 50 pregnant females with PE, group 2 included 50 healthy pregnant females and group 3 included 50 healthy non-pregnant female as a control group. For all groups anthropometric and clinical measurements were performed. Serum RBP-4, resistin, insulin were measured by ELISA and Insulin resistance was calculated by Hemostasis model assessment index (HOMA-IR). Our results showed that serum RBP-4 and resistin concentrations were elevated in PE [39(33.25-40.87) ug/ml] & [61(23.5-91.87) ng/ml] compared to normal pregnancy [18.5(8-27.87) ug/ml] & [25.5(12.7-49.12) ng/ml). Moreover, RBP4 but not resistin levels were elevated in severe cases relative to mild cases of PE. Serum levels of RBP4 showed positive significant correlation with [SBP (r=0.38, p= 0.001) & DBP (r=0.32, p=0.01)] which are markers of severity. Fasting insulin was positively correlated with RBP-4 (p=0.04). By multiple linear regression analysis, serum RBP-4 levels were significantly and positively correlated with SBP (P=0.01), while markers of adiposity were not independently associated with resistin. Conclusion: RBP-4 and resistin were up-regulated in PE, furthermore RBP-4 not resistin levels were independently associated with markers of severity of PE. However no clear relationship were observed between HOMA-IR with both RBP-4 and resistin and the role of Insulin resistance in PE was not clearly proved.

  • Histopathological Pattern of Endoscopic Gastric Biopsy in a District
           Hospital in Nigeria: A Review of 118 Consecutive Cases

    • Authors: BM Duduyemi; BA Ojo, OO Olaomi, AS Atiba
      Pages: 83 - 86
      Abstract: Background: The use of endoscopes for visualization of gastric mucosa has improved over times and in taking biopsy for histology. The study sets out to determine the histopathological pattern of gastritis in dyspeptic patients and correlate the histological detection of H. pylori with that of urease breath test (UBT). Method: Prospective study of 118 consecutive patients with chronic dyspepsia who underwent upper gastrointestinal endoscopic examination and UBT using heliprobe. Biopsy of gastric antrum were taken at endoscopy and sent for histopathological analysis. Routine H&E and Giemsa stains were used. Results were recorded and analysed on the basis of sex, age, histology and UBT for H. pylori. Result: There were 118 patients who had endoscopy comprising 58 males and 60 females with male to female ratio of 1:1. Histology revealed varying degrees of chronic gastritis with or without H. pylori, activity, metaplasia, ulceration and dysplasia. Sixty eight (61%) of our patients were positive for H. pylori histologically. Of the first consecutive 66 patients, histology showed 38(57.6%) positive and 28(42.6%) negative; UBT, 46(69.6%) were positive for H. pylori and 20(30.4%) negative. There was a strong correlation between the true positive and true negative patients for the first 66 consecutive cases for both histology and UBT based diagnosis for detecting H. pylori. (Correlation coefficient=0.862, p=0.01). Conclusion: The study showed that histology and UBT are both useful for H. pylori detection. Large multi centre studies should be done to adopt the non-invasive UBT in resource poor economies for the eradication of H. pylori.
