Serological and Molecular Detection of Cytomegalovirus in Aborted Women in Diyala Province, Iraq

Background: Cytomegalovirus (CMV) is a common virus that can infect individuals of all ages. In pregnant women, CMV infection can lead to complications such as congenital CMV infection, which can cause miscarriage, stillbirth, or significant fetal abnormalities. Objective: To evaluate the prevalence of CMV infection in women with and without a history of miscarriage in Diyala Province, Iraq. Methods: A total of 120 women were recruited and divided into three groups: 40 pregnant women with a history of miscarriage, 40 non-pregnant women with a history of miscarriage, and 40 healthy women without a history of miscarriage (control group). Blood samples were collected from each participant and analyzed for the presence of CMV-specific IgG and IgM antibodies using enzyme-linked immunosorbent assay (ELISA). Some positive results were retested to detect the MIE gene region IE-2 (UL122) by real-time PCR and the IE1 (UL123) gene by conventional PCR. Demographic data of study groups were recorded, and statistical analysis was performed using SPSS Version 29. Results: The serological analysis revealed the following prevalence of CMV IgG antibodies: 100% in both pregnant and non-pregnant women with a history of miscarriage, and 95% in the control group of healthy women without a history of miscarriage. For CMV IgM antibodies, the prevalence was 47.5% in pregnant women with a history of miscarriage, 40% in non-pregnant women with a history of miscarriage, and 7.5% in the control group of healthy women without a history of miscarriage. The PCR results showed that 9 of the samples were positive for both the UL122 and UL123 genes. Conclusion: The study indicates a high prevalence of CMV infection among women with a history of miscarriage in Diyala Province, Iraq. Routine screening for CMV in pregnant women, especially those with a history of miscarriage, is recommended to reduce potential risks and improve pregnancy outcomes.

Maternal Cytomegalovirus (CMV) Serology: The Diagnostic Limitations of CMV IgM and IgG Avidity in Detecting Congenital CMV Infection.

Congenital cytomegalovirus (cCMV) is a common congenital viral infection. Testing for cCMV usually begins with assessing maternal CMV serology, specifically IgM and IgG antibodies. A negative maternal CMV IgM suggests a low risk of recent maternal CMV infection, thereby suggesting a low risk of cCMV in the fetus. Consequently, cCMV is often ruled out when maternal CMV IgM is negative. In our perinatal autopsy and placental pathology database, we identified 5 cases of cCMV despite negative maternal CMV IgM results in the second trimester. In all 5 cases, fetal abnormalities were first detected by ultrasound in the second trimester, prompting maternal CMV testing. Since second trimester maternal CMV IgM was negative in all cases, cCMV was considered unlikely, thus precluding further prenatal CMV testing in 4 of these cases. The diagnosis of cCMV was subsequently made through placental and/or autopsy examinations. Following this diagnosis, retrospective CMV serology and IgG avidity testing was performed on stored frozen first-trimester maternal blood samples in 3 cases. Among these, the first-trimester samples in 2 cases were IgG+, IgM+, and exhibited low IgG avidity, suggesting a primary maternal CMV infection around the time of conception. In the third case, both first and second-trimester maternal blood samples were IgG+, IgM-, and showed high IgG avidity, suggesting a non-primary maternal CMV infection (i.e., reactivation or reinfection of CMV). A negative maternal CMV IgM in the second trimester cannot exclude cCMV infection. While CMV IgG avidity testing and analysis of stored frozen first-trimester maternal blood samples provide valuable insights, they have limitations. CMV PCR performed on amniotic fluid is a useful prenatal diagnostic tool. For cases of unexplained fetal abnormalities or death, autopsy and placental examination are recommended.

Relations of optimism and purpose in life to immune markers in aging

ObjectiveOptimism and purpose in life are associated with improved health outcomes. More information is needed on biological mechanisms, including immunosenescence. We investigated if psychological well-being is associated with healthier immunosenescence-related measures including naïve and terminally differentiated CD4+ and CD8+ T cell percentages, CD4+:CD8+, and cytomegalovirus (CMV) IgG response. MethodsParticipants were adults over age 50 from the Health and Retirement Study. Optimism was measured using the Life Orientation Test Revised. Purpose in life was assessed using the subscale from the Ryff psychological well-being measure. We examined the cross-sectional associations of optimism and purpose in life with measures of T cell subsets using linear regression and with CMV IgG using ordered logit regression, controlling for potential confounding factors. ResultsThe final analytic sample ranged from 7250 to 7870. After adjusting for sociodemographic factors, a 1-SD increment in optimism was associated with the percentage of naïve CD4+ T cells increasing by 0.6 (95%CI 0.2%, 1.0%). A 1-SD increment in purpose in life was associated with the percentage of naïve CD4+ T cells increasing by 0.9 (95%CI 0.5%, 1.3%) after adjusting for sociodemographic factors and the association was maintained after further adjustments for health conditions, depression, and health behaviors. For naïve CD8+ T cell percentages, CD4:CD8 ratios, and CMV IgG antibodies, associations were seen only in models that adjusted for age. No significant associations were seen in any models for the terminally differentiated CD4+ and CD8+ T cells. ConclusionsWe found associations of optimism and purpose in life with naïve CD4+ T cell percentages.

COMPARISON SEROPREVALENCE OF TOXOPLASMA GONDII, RUBELLA, AND CYTOMEGALOVIRUS IN MUŞ PROVINCE BEFORE AND DURING THE COVID-19 PANDEMİC

The aim of this study is to determine the seroprevalence of Toxoplasma gondii (T. gondii), rubella and cytomegalovirus (CMV) and the primary infection rates of these agents with avidity test in pregnant women in Muş province. Additionally, the effect of prevention and protection measures implemented during the Covid-19 pandemic on the prevalence of T. gondii, rubella and CMV in pregnant women was also investigated. Between 2018 and 2021, IgG and IgM antibodies in the serum samples of pregnant women who applied to the Department of Gynecology and Obstetrics polyclinic of Muş State Hospital were examined by enzyme-linked immunosorbent assay (ELISA) and chemiluminescence immunoassay (CLIA). High and low avidity assays were examined by enzyme linked fluorescence assay (ELFA). Low seroprevalence of T. gondii IgG antibody (28%) and the detection of low avidity detection in 38 of 102 pregnant women indicate that this parasite may be a risk for intrauterine life. Rubella IgG (89%) and CMV IgG (99%) antibodies were found to carry a low risk due to their high seroprevalence and avidity. It was determined that Covid-19 prevention and protection measures caused a significant decrease in the prevalence of rubella and CMV, but had no effect on the prevalence of T.gondii.

Cytomegalovirus seronegativity rate in pregnant women and primary cytomegalovirus infection during pregnancy in rural Germany

BackgroundCongenital cytomegalovirus (CMV) infection is the most common congenital infection worldwide and one of the leading causes of congenital hearing loss in newborns. The aim of this study was to determine the seroprevalence rate for cytomegalovirus in pregnant women and the rate of CMV serological testing utilised during pregnancy in a rural region in Germany.MethodsRetrospective data on the prevalence of CMV IgG and IgM antibodies were obtained from 3,800 women, identified in the study group of 19,511 pregnant women from outpatient settings whose samples were collected between 1 and 2014 and 30 April 2018. In addition, the serological CMV status in regards to various billing methods was further analyzed.ResultsSerological CMV tests were performed in 3,800 (19.5%) out of 19,511 pregnant women. 2,081 (54.8%) of these women were CMV seronegative. Among those, seroconversion rate of 0.37–1.42% was identified. A proportion of 2,710 (14.7%) of all 18,460 women with statutory health insurance made use of the CMV testing as an individual health service.ConclusionsThe low uptake of CMV serological testing in the study population covered indicates low risk awareness among pregnant women and their healthcare professionals. Presented seronegativity rates and routine seroconversion rate, demonstrate importance to improve intervention strategy to prevent feto-maternal CMV transmission.

Personality and aging-related immune phenotype

An aging-related immune phenotype (ARIP) has been defined as a decrease in naïve T cells (TN) relative to the accumulation of memory T cells (TM). Recent research implicates ARIP measures, such as CD4 +TN/TM and CD8 +TN/TM ratios, in multimorbidity and mortality. This study examined whether psychological dispositions that assess how people think, feel, and behave are related to CD4 +TN/TM and CD8 +TN/TM. Participants were adults aged 50–104 years (N = 4798; 58% women, Mean Age= 67.95, SD= 9.56) from the Health and Retirement Study. Data on CD4 +TN/TM and CD8 +TN/TM were obtained in 2016. Data on personality, demographic factors, and potential clinical (body mass index, disease burden), behavioral (smoking, alcohol, physical activity), psychological (depressive symptoms, stress), and biological (cytomegalovirus IgG antibodies) mediating factors were obtained in 2014/2016. Controlling for demographic factors, higher conscientiousness was related to higher CD4 +TN/TM and CD8 +TN/TM. To a lesser extent, higher neuroticism and lower extraversion were associated with lower CD4 +TN/TM. Physical activity, and to a lesser extent BMI and disease burden, were the most robust mediators between personality and ARIP measures. Cytomegalovirus IgG level mediated the association between conscientiousness and both CD4 +TN/TM and CD8 +TN/TM. This study provides novel evidence that personality is related to ARIP. Higher conscientiousness and, to a lesser extent, higher extraversion may be protective against age-related immunophenotype change, whereas neuroticism may be a risk factor.

Prevalence of cytomegalovirus IgG antibodies among women in Buguma, Rivers State, Nigeria

Cytomegalovirus (CMV) is a ubiquitous virus that belongs to the family of herpes virus. CMV causes serious illness in immuno-compromised patients and congenitally infected neonates. This study was conducted to determine the prevalence of the immunoglobulin (IgG) antibodies to cytomegalovirus among women in Buguma-City, Rivers State, Nigeria. Blood samples were collected from 93 women from Buguma-City Health Centre between February and August 2022. Serum obtained from the blood samples was examined for CMV IgG antibodies by ELISA method. Among the 93 women investigated, 89 (95.7%) were seropositive for Cytomegalovirus IgG antibodies. A total prevalence rate of 100.0% was recorded in the age group of 20 to 30 years, with the highest prevalence, while 89.5% was found in the age group of 31 to 56 years. Among the 38 single women, all were found to be seropositive (100.0%) for Cytomegalovirus antibodies, while 51 (92.7%) of the 55 married women were seropositive. The women with a secondary level of education had a higher prevalence of 97.0% than those with a tertiary level of education, which had a prevalence of 95.0%. The unemployed women had a higher prevalence (95.8%) than the employed, which had a prevalence of 95.7%. The results were statistically significant with age (p = 0.01). There was no significant association (p>0.05) between CMV infection, marital status, education and occupation. The high prevalence of CMV infection observed in this study indicates that the virus is prevalent in the study area. Therefore, routine screening for CMV infection is advisable for all antenatal women in the State.

Efficiency of CMV serodiagnosis during pregnancy in daily laboratory routine

BackgroundMaternal acute primary cytomegalovirus (CMV) infection during the first trimester may cause severe long-term sequelae in newborns. For risk assessment, serological screening is routinely performed in pregnant women based on IgM, IgG and avidity tests using whole-virus antigen. A recent study evaluated the diagnostic value of recombinant protein-based ELISAs as second-line tests in pregnancy CMV screening, including anti-p52 IgM and anti-gB IgG as markers defining the early and late phase of infection, respectively. In the present study, these recombinant ELISAs were used as first-line screening tests in daily laboratory routine and compared to lysate-based assays with respect to [i] the number of conclusive results obtained with the initial sample and [ii] the underlying workload. Methods553 unselected routine serum samples from pregnant women were tested for anti-CMV IgM and IgG antibodies using lysate-based ELISAs and avidity testing. Anti-CMV IgM antibodies against recombinant p52 and anti-CMV IgG antibodies against recombinant glycoprotein B (gB) were also determined by ELISA. All assays were performed and interpreted according to the manufacturer’s instructions. ResultsFor lysate-based IgM, IgG and avidity testing, 84.6 % of samples yielded conclusive results in a total of 1156 tests, while 15.4 % needed follow-up testing of a consecutive sample. Anti-p52 CMV IgM and anti-gB CMV IgG testing produced conclusive results for 92.8 % of samples in a total of 1026 tests, while 7.2 % samples required follow-up testing. ConclusionsThe first-line use of ELISAs measuring anti-p52 CMV IgM and anti-gB CMV IgG antibodies to test for maternal CMV infection increases the number of conclusive results derived from an initial serum sample while requiring a considerably lower number of tests compared to the lysate-based approach. For day-to-day routines in a diagnostic laboratory, this high efficiency of the recombinant testing approach has significant practical relevance.

Serologic evaluation of cytomegalovirus (CMV), Toxoplasma gondii and Brucella in schizophrenia patients.

Infectious agents are considered as a possible cause of schizophrenia. The aim of this study was to evaluate the serum levels of cytomegalovirus (CMV), Toxoplasma gondii and Brucella antibodies in schizophrenia patients compared with the control group. This cross-sectional study was performed on 75 patients with schizophrenia who were clinically diagnosed with schizophrenia using the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) by two independent psychiatrists. As the controls, 75 sex and age-matched individuals were selected from orthopedic and surgical wards, who were admitted because of trauma. Anti-Toxoplasma gondii IgG antibody was detected by Abbott's company diagnostic kit. To detect anti-Brucella IgG antibodies, the enzyme-linked immunosorbent assay (ELISA) test with Vircell diagnostic kit was used. Quantitative luminescence (CLIA) method using Abbott diagnostic kit was also used to detect anti-cytomegalovirus IgG antibody (CMV IgG avidity). There was not any clinically significant differences in the mean value of Toxoplasma, CMV and Brucella IgG antibodies between schizophrenia and control group. However, considering cut-off point for these tests and further analysis with non-parametric tests showed clinically significant difference between two groups at cut-off point 1.1 for anti-Brucella IgG antibody which indicated more positive samples in schizophrenia group (24 out of 75) than control group (12 out of 75) with a p-value less than 0.05 (0.046). The results of the present study showed no association between toxoplasmosis infection and CMV and schizophrenia. However, there might be a positive correlation between anti-Brucella IgG antibody and schizophrenia.

Maternal cytomegalovirus infection and delayed language development in children at 3 years of age-a nested case-control study in a large population-based pregnancy cohort.

Maternal cytomegalovirus (CMV) infection in pregnancy may result in vertical transmission of CMV to the child. Long-term effects of congenital CMV infection include visual, cognitive as well as neurological impairment. The aim of this study was to estimate the odds ratios for CMV seropositivity and seroconversion in mothers, with and without delayed language development in 3 year old children, nested within a large cohort. The Norwegian Mother, Father and Child Cohort Study (MoBa) is a prospective population-based pregnancy cohort that includes 95 200 mothers and 114 500 children. Blood samples were obtained from mothers during pregnancy weeks 17 or 18 in pregnancy and after birth. We included 300 women from MoBa with children suffering from delayed language development at three years of age, based on validated questionnaires. Within the cohort, 1350 randomly selected women were included as controls to perform a nested case-control study. The cases and controls were tested for CMV IgG antibodies by an enzyme-linked immunosorbent assay. Among mothers of cases, 63.2% were CMV-IgG positive in the sample at birth, as compared to 55.9% among controls; OR 1.36, (95% CI; 1.05 to 1.76). Also, among case mothers, 8/118 (6.8%) initially seronegative cases, seroconverted. Among initially seronegative controls, seroconversion occurred in 23/618 (3.7%) mothers. The OR for seroconversion in cases as compared to control mothers was 1.88 (CI; 0.82 to 4.31), thus not statistically significant different. This study shows a higher risk of delayed language development at three years of age in children born by mothers seropositive for CMV, compared to children born from seronegative mothers.

Clinical features and prognostic factors of children with profound sudden sensorineural hearing loss.

To investigate the clinical features and factors affecting the prognosis of children with profound sudden sensorineural hearing loss (SSNHL). We retrospectively analyzed the clinical data of 147 children with profound SSNHL who received inpatient treatment at our department from January 2016 to January 2021. All children were administered with systemic steroid therapy and/or intratympanic steroid (ITS) treatment for 2 weeks. Statistical analyses were performed for the clinical features, treatment effectiveness, and factors affecting the prognosis using SPSS 23.0. The median age of the study population was 8 (6-10) years. The median treatment onset time was 8 (4-20) days. The most common concomitant symptom was tinnitus (45.58%). Laboratory findings showed that the percentages of children with abnormal leukocytes was 25.85%, abnormal platelet counts was 17.01%, abnormal cytomegalovirus IgG antibodies was 36.73% and abnormal Epstein-Barr (EB) virus IgG antibodies was 41.50%. The overall recovery rate of the treatment was 20.04%. The univariate analysis showed that age, treatment onset time, tinnitus, and ITS treatment were associated with the prognosis (p < 0.05). Regarding laboratory findings, the neutrophil count, lymphocyte count, and neutrophil-to-lymphocyte ratio differed significantly between the effective and invalid treatment effect groups (p < 0.05). The multivariable logistic regression analysis showed that treatment onset time [odds ratio (OR) = 0.936, 95% confidence interval (CI): 0.881-0.994] and ITS treatment (OR = 0.174, 95% CI: 0.044-0.0687) correlated with hearing recovery (p < 0.05). In this study, the earlier the treatment start time of children with profound SSNHL, the better was the prognosis. Further, ITS could be an effective treatment option.

Seroprevalence of cytomegalovirus antibodies among aborted women in Ibb city-Yemen

Abortion is one of the most common health problems in the world, its causes vary, and some of them are viral. Cytomegalovirus (CMV) is one of the causes of abortion. So, this study aims to investigate the seroprevalence of CMV antibodies among aborted women. This study was a cross-sectional study conducted in Ibb city-Yemen. Serum samples were collected between September 2021 to April 2022. The serum samples were analyzed for IgG and IgM antibodies to CMV by Electro-Chemiluminescence Immunoassay (ECLIA). Overall, 150 aborted women were enrolled. Amongst these cases, 148 out of 150 (98.67%) were positive for CMV IgG antibodies. Additionally, 11 out of 150 (7.33%) of the samples were positive for CMV IgM antibodies. The CMV IgG seroprevalence was not significantly influenced by age, residence, education level, socioeconomic status and abortion time. In addition, the CMV IgM seroprevalence was significantly associated with education level, socioeconomic status and abortion time. In conclusion, the low rate of CMV IgM and a high proportion of CMV IgG for most major of abortion women in this study suggest that CMV may not be the common factor leading to abortion.

Status of CMV IgM Seropositivity Before and After Starting Chemotherapy in Patients with Haematological Malignancies

Background: Even after significant improvement of management of haematological malignancy, post chemotherapy infection is still causing significant mortality and morbidity. Cytomegalovirus (CMV) is an important cause of morbidity and mortality in immunocompromised patients. This study was designed to assess prospectively the status of CMV IgM seropositivity in patients with haematological malignancy at diagnosis and after starting chemotherapy by serology test. In Bangladesh the prevalence IgG is high and IgM is low in general population but in patients with chemotherapy due to haematological malignancy status of CMV infection is not known. By finding out the infection rate we will be able to provide supportive care more effectively to patients of chemotherapy due to haematological malignancy. &#x0D; Methodology: This was a prospective type of observational study and patients were selected by purposive sampling. Assessment of CMV IgG and IgM antibody test had been done at the time of 1st diagnosis and IgM antibody for CMV reassessed 6 weeks after initial chemotherapy. Antibodies were detected by Chemiluminescence method from Virology department of BSMMU. Statistical analysis was done both manually and Windows based software device with Statistical Package for Social Science (SPSS). A p-value of &lt;0.05 was taken as significant during data calculation. Result: During 12 months study period a total 45 patients with haematological malignancy were included in the study. Out of 45 patients, 28 were male (62%) and 17 were female (38%), male female ratio was 1.65:1. The youngest of the participants was 15 and oldest was 70 years old. The mean age of the participants was 35.77 years with SD of 16.93. Among 45 patients of the study, ALL patients were 20 (44.4%), AML patients were 17 (37.8%), NHL patients were 5 (11.1%) and HD patients were 3 (6.7%). Before chemotherapy all participants were CMV IgG positive (100%) no one was CMV IgM Positive (0%). Six weeks after chemotherapy, 42 (93.3%) cases were CMV IgM antibody negative and only 3 (6.7%) cases were positive for CMV IgM antibody. McNemar test was done to measure the level of significance and p-value was 0.250, which was not significant statistically. Conclusion: This small study found that all participants were CMV IgG seropositive (100%). It indicates that higher percentages of haematological malignancy patients are previously infected with CMV so there is more risk of reactivation after chemotherapy or BMT. Post chemotherapy CMV IgM seropositivity (new infection or reactivation of CMV) was low 6.7% in this study. This percentage is low in comparison with other studies. Percentage could be high if the tests were carried out with more sensitive and specific tests for CMV like PCR, pp65 antigenaemia or CMV DNA.

Higher Viral Load of Polyomavirus Type BK but not JC among Renal Transplant Recipients in Comparison to Donors.

Background & Objective:Polyomaviruses types BK and JC and Cytomegalovirus (CMV) have been shown to be related to kidney transplantation complications. This study aimed to assess the prevalence of these viruses in patients receiving kidney transplantation. Methods:This cross-sectional study was performed on 40 kidney transplant recipients and 44 donors. Urine samples were used for the extraction of viral DNA. The prevalence of JC and BK viruses and their viral loads were determined by real-time polymerase chain reaction.Results:JC and BK viruses were identified in 31% and 92.3% of all subjects, respectively. The frequency of JC and BK cases was not statistically different between the recipient and donor groups (P>0.05). All patients in the donor group and 96.8% of the recipients were positive for CMV IgG antibody. The mean viral load of BK in donors and recipients was 4.5×1010 and 3.3×1011 copies, respectively. The mean viral load of JC was 8.6×107 copies in donors and 2.9×108 copies in recipients. The distribution of BKV was significantly higher in recipients than donors (P=0.001), while no difference was observed between the two studied groups for JCV. Conclusion:This study showed a relatively high prevalence of BK and JC viruria in both renal transplant donors and recipients. The viral load for BKV, but not JCV, was higher in recipients than in donors.

Clinical manifestations

Cytomegalovirus (CMV) is the main infectious virus that leads to neurological disabilities in children such as congenital sensorineural deafness. Transmission of the virus can happen through direct contact with abody fluids, saliva, urine, and blood products. Congenital infections are the result of transplacental transmission of CMV. In utero, transmission occurs in about one third of women who develop primary infection in the first trimester. The first step for the diagnosis of infection is the laboratory confirmation, where conversion of CMV IgG antibody from negative to positive is the first thing that raises the suspicion of infection. If both IgG and IgM antibody to CMV are positive when first tested, the next step is testing for avidity of CMV IgG antibody. Low IgG antibody avidity and presence of IgM antibody is strong evidence of recent primary infection. At present, there is no vaccine available against CMV and treatment options for pregnant women are still developing. It has been shown that in attempt to reduce the rate of primary maternal CMV infections, public health strategies based on sanitary measures can have a real impact.

ASSOCIATION OF SEROPOSITIVITY FOR CMV IGM AND IGG WITH ADVERSE PREGNANCY OUTCOME

Objective: To find out the prevalence of antibodies against cytomegalovirus and their association with adverse pregnancy outcome in women, at Isra University Hospital Hyderabad.&#x0D; Study Design: Cross-sectional study.&#x0D; Place and Duration of Study: Department of Gynaecology &amp; Obstetrics, Isra University Hospital (IUH) Hyderabad, from Jan to Jun 2018.&#x0D; Methodology: Cytomegalovirus IgM and IgG antibodies in 305 women of reproductive age group were measured using the Enzyme Linked Fluorescent Assaysystem kit.&#x0D; Results: The combined positivity of anti cytomegalovirus IgG and IgM antibodies was 93 (30.40%). About 37 (37.37%) and 28 (34.14%) women were found to be seropositive for cytomegalovirus antibodies who had history of spontaneous miscarriage and recurrent miscarriages respectively.&#x0D; Conclusion: Higher association of seropositivity for cytomegalovirus IgM and IgG with bad obstetrical history and low economy was found.

Keywords: Putraghani yonivyapada, Recurrent pregnancy loss, Habitual abortion

A study on some factors affecting CMV reactivation in allogeneic hematopoietic stem cells transplantation

Background: In developing countries, cytomegalovirus (CMV) seropositivity has been widely propagated. Following hematopoeitic stem cell transplantation, the apparent risk of CMV reactivation increases. With effective surveillance and study of the effect of some factors on CMV reactivation, timely treatment with anti-viral treatment may decrease morbidity and mortality associated with CMV reactivation. Aim: This study aimed to evaluate the effect of some factors on CMV reactivation in allogeneic hematopoietic stem cell transplantation (HSCT). Materials & Methods: We retrospectively analyzed 25 patients with Serostatus positive of CMV IgG antibodies who underwent allogeneic hematopoietic stem cell transplantation at two Bone Marrow Transplantation centers in Egypt from November 2016 to June 2017. Results: In our study, the patient male percentage was 57.1% in CMV reactivation group with the most common pre-transplantation diagnosis was FA, CML and βTM. All donors in the reactivation group (100 %) were positive for CMV IgG ab. This group had 42.9% matching donors in sex and blood groups. While the stem cell source was 92.9% peripheral blood source with a median dose of 7.0 cells ×106 ∕ kg. Conclusion: The incidence of CMV infection following hematopoietic stem cell transplantation is comparable to that recorded in Western literature because of a higher seroprevalence rate in developing countries. More research is needed to study factors affecting cytomegalovirus reactivation in allogeneic hematopoietic stem cells transplantation (HSCT).

Establishment of a sandwich light-initiated chemiluminescence assay with double antigen for detecting human cytomegalovirus IgG antibody.

Determination of human cytomegalovirus IgG (HCMV IgG) level is of great importance in the diagnosis of HCMV infections. In this study, a novel, double antigen sandwich homogeneous immunoassay-based light-initiated chemiluminescent assay (LICA) for measuring HCMV IgG serum levels was developed. This sandwich LICA for HCMV IgG was performed by incubating serum samples with HCMV pp150 protein coated with chemibeads, streptavidin-coated sensibeads, and biotinylated HCMV pp150 protein. The working conditions of this assay were optimized and the correlation between the results of the LICA and enzyme-linked immunosorbent assay was evaluated. As a homogeneous immunoassay, this sandwich LICA could accurately and rapidly determine the serum levels of HCMV IgG with a high-throughput. Thus, this newly developed assay could be a useful analytical tool in the clinical diagnosis of HCMV infections.

Seroprevalence of CMV IgG and IgM in Korean women of childbearing age.

BackgroundThe aim of this study was to investigate the seroprevalence of cytomegalovirus (CMV) infection using the serologic status of CMV IgG and IgM antibodies in Korean women of childbearing age.MethodsWe retrospectively reviewed CMV IgG and IgM test results from Korean women aged 15–49 years who underwent testing between January 2009 and December 2019. Seroprevalence of CMV IgG and IgM by year and age was investigated.ResultsThe study period was 11 years, and among 6837 samples tested, 95.8% were CMV IgG–positive. The seropositivity in women aged 15‐ <20 years was significantly lower (77.5%) than older age groups. Among 6837 total CMV IgG tests, 75.9% (5186) had concurrently measured CMV IgM results among which 2.4% were IgM‐positive.ConclusionConsidering the low CMV seropositivity of women younger than 20 years, they may need prenatal education for CMV infection.
