Abstract
Background Toxoplasmosis during pregnancy can causes adverse outcomes. Regarding its importance in prenatal care, seroprevalence of Toxoplasma gondii infection among pregnant women was studied in Ardabil City, during 2021-2022. Methods In a cross-sectional study with a cluster sampling, 244 pregnant women that attended in health care centers of Ardabil City, Ardabil Province, Iran in 2021-2022 were selected. Serum samples were collected and Anti-Toxoplasma IgM (immunoglobulin M) and IgG (immunoglobulin G) was detected. Furthermore, a questionnaire filled for all participants during samples collection and risk factors assessed. Data were analyzed by SPSS software. Results Participant's age ranged from 16 to 43 years with average of 23± 5.24 years. IgG anti-T. gondii antibody was detected in 22.1% of pregnant women (54/244). In none of participants IgM anti-Toxoplasmosis antibody was detected. There was no significant relationship between demographic variables and risk factors of toxoplasmosis with serology test results. Conclusion Approximately, 77.9% of pregnant women had no antibody against the T. gondii infection. Therefore, health education, counseling of pregnant women and screening in high-risk pregnant women is recommended to prevent from fetal complications.

Comparison of an in house and a commercial real-time polymerase chain reaction targeting Toxoplasma gondii RE gene using various samples collected from patients in Turkey.

Abstract
Background Toxoplasma gondii is an opportunistic protozoan parasite that can infect all warm-blooded animals including humans and cause serious clinical manifestations. Toxoplasmosis can be diagnosed using histological, serological, and molecular methods. In this study, we aimed to detect T. gondii RE gene in various human samples by in house and commercial real time polymerase chain reactions. Methods A total of 38 suspected cases of toxoplasmosis [peripheral blood (n:12), amnion fluid (n:11), tissue (n:9), cerebrospinal fluid (n:5), and intraocular fluid (n:1)] were included to the study. An in house and a commercial RT-PCR were applied to investigate the T. gondii RE gene in these samples. Results The compatibility rate of the two tests was 94.7% (37/38). When the commercial RT-PCR kit was taken as reference, the sensitivity and specificity of in house RT-PCR test was 87.5 and 100%. When the in house RT-PCR test was taken as reference, the commercial RT-PCR kit has 100% sensitivity and 96.8% specificity. Incompatibility was detected in only in a buffy coat sample with high protein content. Conclusions Both the commercial and in house RT-PCR tests can be used to investigate T. gondii RE gene in various clinical specimens with their high sensitivity and specificity. In house RT-PCR assay can be favorable due to cost savings compared to using the commercial test.

Sero-epidemiological status and risk factors of toxoplasmosis in pregnant women in Northern Vietnam. BMC Infect Dis 2019; 19:329. [PMID: 30999869 PMCID: PMC6471880 DOI: 10.1186/s12879-019-3885-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2018] [Accepted: 03/06/2019] [Indexed: 11/29/2022] Open
Abstract
Background In Vietnam, few studies have determined the epidemiological status of toxoplasmosis in pregnant women and no routine prenatal screening is in place. This study was conducted to evaluate the seroprevalence of this zoonotic parasitic infection in pregnant women in Northern Vietnam and to assess the association with awareness, risk factors and congenital toxoplasmosis. Methods Approximately 800 pregnant women were included in the study from two hospitals, one in Hanoi and one in Thai Binh province, which is known to have a dense cat population. Serological immunoglobulin G (IgG) and immunoglobulin M (IgM) detection was performed to estimate the seroprevalence of toxoplasmosis and sero-incidence of maternal and congenital toxoplasmosis. In addition, a survey was conducted about awareness, clinical history, presentation of signs and symptoms relating to toxoplasmosis and to detect biologically plausible and socio-demographic risk factors associated with toxoplasmosis. Associations with seroprevalence were assessed using univariable and multivariable analysis. Results The mean IgG seroprevalence after the full diagnostic process was 4.5% (95% confidence interval(CI): 2.7–7.0) and 5.8% (95% CI: 3.7–8.6) in Hanoi and Thai Binh hospital, respectively, and included one seroconversion diagnosed in Thai Binh hospital. Only 2.0% of the pregnant women in Hanoi hospital and 3.3% in Thai Binh hospital had heard about toxoplasmosis before this study. Conclusion Since the percentage of seronegative, and thus susceptible, pregnant women was high and the awareness was low, we suggest to distribute information about toxoplasmosis and its prevention among women of child bearing age. Furthermore, future studies are recommended to investigate why such a low seroprevalence was seen in pregnant women in Northern Vietnam compared to other countries in South East Asia and globally.
