Toxoplasma Gondii Infection

Abstract Introduction Infections caused by Toxoplasma gondii is a great public health concern worldwide. Toxoplasma gondii infection in pregnant women may result in abortion, stillbirth, or lifelong disabilities of the fetus. Serologic studies have reported various estimates for seroprevalence of toxoplasmosis among African pregnant women. Estimation of the pooled seroprevalence of this infection is necessary for policy-making and target intervention. Methods We conducted this systematic review and meta-analysis according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A rigorous literature selection was performed by using the databases of PubMed, Google Scholar, and ScienceDirect for the period Jan 1, 2001, to July 31, 2019. Sero-prevalence with 95% CI was presented for each study, and point estimates and their 95% CIs of pooled seroprevalence was then calculated. Findings The search process resulted in the inclusion of a total of 36 studies in the systematic review and meta-analysis. The pooled seroprevalence of Toxoplasma gondii Immunoglobulin G (IgG) in Africa was found to be 46.7% (95%CI: 37.0, 56.4). Geographical-based subgroup analysis showed that the seroprevalence of T. gondii among pregnant women was found to be 65.1% (95% CI: 44.7, 85.5), 50.2% (95% CI: 32.0, 68.3), 47.8% (95% CI: 31.7, 63.8), 38.3% (95% CI: 25.2, 51.4) and 5.8% (95% CI: 3.6, 8.1) in Central, Eastern, Northern, Western and Southern Africa respectively. The most common risk factors for T. gondii were living or contact with cat and consumption of raw vegetables or fruits. Conclusion The current systematic review and meta-analysis revealed a high seroprevalence of Toxoplasma gondii infection among pregnant women. There is a need to establish prevention and control measures that should be directed to educational programs. We recommend that periodic screenings for Toxoplasma gondii infection among pregnant women should be incorporated into routine clinical care in order to avoid serious clinical complications of mother and fetus.

Toxoplasma Gondii Infection

Abstract Schizophrenia is associated with an increased prevalence of IgG antibodies against Toxoplasma gondii (T. gondii seropositivity), whereby the infection seems to precede the disorder. However, it remains unclear whether a T. gondii infection affects clinical characteristics of schizophrenia. Therefore, a systematic review and meta-analysis was conducted following PRISMA guidelines examining the association between T. gondii seropositivity and severity of total, positive, or negative symptoms or age of onset in schizophrenia. PubMed, Embase, and PsycInfo were systematically searched up to June 23, 2019 (PROSPERO #CRD42018087766). Random-effects models were used for analysis. Furthermore, the influence of potential moderators was analyzed. Indications for publication bias were examined. From a total of 934 reports, 13 studies were included. No overall effect on severity of total, positive, or negative symptoms was found. However, in patients with a shorter duration of illness T. gondii seropositivity was associated with more severe positive symptoms (standardized mean difference [SMD] = 0.32; P < .001). Similar but smaller effects were seen for total symptoms, while it was absent for negative symptoms. Additionally, a significantly higher age of onset was found in those with T. gondii seropositivity (1.8 y, P = .015), although this last finding was probably influenced by publication bias and study quality. Taken together, these findings indicate that T. gondii infection has a modest effect on the severity of positive and total symptoms in schizophrenia among those in the early stages of the disorder. This supports the hypothesis that T. gondii infection is causally related to schizophrenia, although more research remains necessary.

Background Toxoplasma gondii is an obligate intracellular and neurotropic apicomplexan protozoan parasite infecting almost all warm-blooded vertebrates including humans. To date in Ethiopia, no systematic study has been investigated on the overall effects of potential risk factors associated with seropositivity for Toxoplasma gondii among pregnant women and HIV infected individuals. We intended to determine the potential risk factors (PRFs) associated with seropositivity for Toxoplasma gondii from published data among pregnant women and HIV infected individuals of Ethiopia. Methodology An systematic review of the previous reports was made. We searched PubMed, Science Direct, African Journals Online, and Google Scholar for studies with no restriction on the year of publication. All references were screened independently in duplicate and were included if they presented data on at least two risk factors. Meta-analysis using the random or fixed-effects model was made to calculate the overall effects for each exposure. Results Of the 216 records identified, twenty-four reports met our eligibility criteria, with a total of 6003 individuals (4356 pregnant women and 1647 HIV infected individuals). The pooled prevalences of anti-Toxoplasma gondii antibodies were found at 72.5% (95% CI: 58.7% - 83.1%) in pregnant women and 85.7% (95% CI: 76.3% - 91.8%) in HIV infected individuals. A significant overall effect of anti-Toxoplasma gondii seropositivity among pregnant women (p < 0.05) was witnessed with age, abortion history, contact with cats, cat ownership, having knowledge about toxoplasmosis, being a housewife and having unsafe water source. Age, cat ownership, and raw meat consumption were also shown a significant effect (p < 0.05) to anti-Toxoplasma gondii seropositivity among HIV infected individuals. Conclusions This review showed gaps and drawbacks in the earlier studies that are useful to keep in mind to design accurate investigations in the future. The pooled prevalence of anti-Toxoplasma gondii antibodies was found to be higher among pregnant women and HIV infected individuals. This suggests that thousands of immunocompromised individuals (pregnant women and HIV infected patients) are at risk of toxoplasmosis due to the sociocultural and living standards of the communities of Ethiopia. Appropriate preventive measures are needed to reduce the exposure to Toxoplasma gondii infection. Further studies to investigate important risk factors are recommended to support the development of more cost-effective preventive strategies.

Background. Although Toxoplasma gondii infection in immune-competent individuals is usually asymptomatic or causes a mild flu-like illness, it may become severe and can occasionally be fatal in immune-compromised people, such as AIDS patients or pregnant women. Method. Electronic English databases (Pubmed, Google Scholar, Science Direct, and Scopus), parasitology congresses, and theses of Ethiopian medical universities, were systematically searched (published or unpublished data). Full-length articles and abstracts were collected using keywords such as Toxoplasma gondii, Toxoplasmosis, pregnant women, HIV/AIDS, and Ethiopia. Results. Analysis of seroprevalence estimates was pooled using a random effects meta-analysis. Seventeen studies were included in the present systematic review and meta-analysis. One of these studies reported seroprevalence of T. gondii in HIV/AIDS patients and pregnant women. In this review, a total of 4,030 individuals were included and analyzed. The pooled prevalence of T. gondii in this review was 81.00% (95% CI = 69.10–89.78). Sub-group analysis showed that 2,557 pregnant women were evaluated. In pregnant women, the pooled sero-prevalence was 71.2 (95% CI = [51.9%, 87.1%]. In HIV/AIDS patients, 1,473 individuals were evaluated and the pooled seroprevalence was 88.45 (95% CI = 80.87%–94.31%). Conclusion. This systematic review and meta-analysis identified a high seroprevalence of Toxoplasma infection of 81% among immunocompromised patients. Scaling up prevention and control methods mainly strengthening educational efforts are necessary to avoid reactivation and to stop the spread of T. gondii infection.
