Congenital toxoplasmosis (CT) and congenital rubella (CR) infections are well-known causes potentially leading to devastating consequences. This report aims to address the prevalence of each of these infections among suspected infants in a pediatric hospital in Baghdad. The study sample includes 120 blood samples of suspected infants consulting Al-Alwyia pediatric teaching hospital over one year. This report represents an extension of a previous article published in Al-Kindy College Medical Journal KCMJ about cytomegalovirus infection (CMV). Using the enzyme-linked immunosorbent assay (ELISA) method, the results show that 5.8% and 5% were positive for specific IgM antibodies for rubella and toxoplasmosis respectively. Results also show that CMV is more common than CT and CR. Although results reported one case of co-existence of IgM antibodies for both CMV and rubella, there was a significant association of negative CMV IgG and IgM results with positive rubella results; and negative rubella results with CMV IgG and IgM results. Conclusions: This short brief addressed the prevalence of CT and CR in Baghdad. A novel finding identified in this brief is the association of the prevalence of CR active infection with negative past and negative recent CMV infections, and the association of prevalence of CMV active and past infections with negative CR infection Recommendations: The study recommends increased awareness, early diagnosis and treatment for congenital infection, and consolidation of coverage of the rubella vaccine for children and girls at premarital age.
Background: Cytomegalovirus (CMV) virus is a recognized important cause of congenital CMV infection which carries a significant risk for symptomatic disease and developmental defects in newborns. Its prevalence varies from place to other and time to time. This study is conducted to estimate its prevalence in Baghdad among infants suspected of having a congenital infection and to study the associated findings. Subjects and Methods: The study was carried out in Al-Alwyia pediatrics teaching hospital. Data were collected, and blood samples were taken for infants suspected to have intrauterine infections over a period of one year, from 1 October 2019 to 1 October 2020. Immunoglobulin M (IgM) tests for CMV were conducted for all collected samples. CMV- immunoglobulin G (IgG) was a further analysis if negative results were obtained for CMV-IgM testing. Samples were tested by Eliza method. Results: The overall positivity for CMV-specific antibodies among suspected infants was 16.7% for IgM and 66 % for IgG. Males constitute 55% of CMV-IgM positive results. These results are statistically significant concerning age groups. 1-3-month age group was the largest (40 % of IgM positive infants) with a p-value of 0.000. This indicates delayed presentation of CMV-affected infants. With the same p-value, 74% of infants less than one month of age were IgG positive reflecting the maternal prevalence of CMV- IgG in an equivalent percentage. Convulsion followed by delayed milestones was the most common presenting symptoms in congenital CMV infection with statistically significant associations. Conclusions: The study indicates that infection with CMV constitutes a significant portion of suspected infants. The study recommends special attention to take steps concerning early management.
