Abdoli A, Ghaffarifar F, Sharifi Z, Taghipour A. Toxoplasma gondii infection and testosterone alteration: A systematic review and meta-analyses. PLoS One 2024; 19:e0297362. [PMID: 38568993 PMCID: PMC10990213 DOI: 10.1371/journal.pone.0297362] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Accepted: 01/03/2024] [Indexed: 04/05/2024] Open
Abstract
BACKGROUND Toxoplasma gondii (T. gondii) is a worldwide distributed protozoan parasite which has infected a wide range of warm-blooded animals and humans. The most common form of T. gondii infection is asymptomatic (latent); nevertheless, latent toxoplasmosis can induce various alterations of sex hormones, especially testosterone, in infected humans and animals. On the other hand, testosterone is involved in behavioral traits and reproductive functions in both sexes. Hence, the purpose of this systematic review is to summarize the available evidence regarding the association between T. gondii infection and testosterone alteration. METHODS In the setting of a systematic review, an electronic search (any date to 10 January 2023) without language restrictions was performed using Science Direct, Web of Science, PubMed, Scopus, and Google Scholar. The PRISMA guidelines were followed. Following the initial search, a total of 12,306 titles and abstracts were screened initially; 12,281 were excluded due to the lack of eligibility criteria or duplication. Finally, 24 articles met the included criteria. A mean±standard deviation (SD) was calculated to assess the difference of testosterone between T. gondii positive and T. gondii negative humans. The possibility of publication bias was assessed using Egger's regression. P-value < 0.05 was considered statistically significant. RESULTS This systematic review identified 24 articles (18 studies in humans and six studies in animals). Most human studies (13 out of 19) reported an increased level of testosterone following latent toxoplasmosis in males, while three studies reported decreased levels and two studies reported an insignificant change. Eleven articles (seven datasets in males and seven datasets in females) were eligible to be included in the data synthesis. Based on the random-effects model, the pooled mean± SD of testosterone in T. gondii positive than T. gondii negative was increased by 0.73 and 0.55 units in males and females, respectively. The Egger's regression did not detect a statistically significant publication bias in males and females (p = value = 0.95 and 0.71), respectively. Three studies in male animals (rats, mice, and spotted hyenas) and two studies in female animals (mice and spotted hyenas) reported a decline in testosterone in infected compared with non-infected animals. While, one study in female rats reported no significant changes of testosterone in infected than non-infected animals. Moreover, two studies in male rats reported an increased level of testosterone in infected than non-infected animals. CONCLUSIONS This study provides new insights about the association between T. gondii infection and testosterone alteration and identifies relevant data gaps that can inform and encourage further studies. The consequence of increased testosterone levels following T. gondii infection could partly be associated with increased sexual behavior and sexual transmission of the parasite. On the other hand, declining testosterone levels following T. gondii infection may be associated with male reproductive impairments, which were observed in T. gondii-infected humans and animals. Furthermore, these findings suggest the great need for more epidemiological and experimental investigations in depth to understand the relationship between T. gondii infection and testosterone alteration alongside with future consequences of testosterone alteration.

Abstract
Toxoplasmosis is a worldwide disease of various animals and human and results from infection with the Toxoplasma gondii parasite. Abortion and congenital defects are important consequences of the T. gondii infection. The aim of this study was to determine the Toxoplasma-induced abortions among women with miscarriage and the presence of T. gondii in their aborted fetuses in Urmia, the northwest of Iran. This cross-sectional study was conducted with 215 women with abortion and their aborted fetuses, from 2020 to 2021. Seroprevalence of anti-Toxoplasma IgG and IgM were determined using the sera of the aforesaid women. Nested PCR was carried out using RE-529 gene sequences, and sequencing was performed using the T. gondii GRA6 gene on the remnant of pregnancy after abortion. The tissue positive samples were then subjected to another PCR on GRA6 gene and sequenced for genotyping. Among 215 serum samples of women with abortion, 70 (32.6%) were positive for anti-Toxoplasma IgG, and three (1.4%) were positive for IgM. The RE-529 sequence of T. gondii was positive in three (1.4%) of the aborted fetuses. The analysis of GRA6 gene indicated that all three positive samples carried a GRA6 allele (GRA6I) of T. gondii type I genotype. Our findings suggest that T. gondii is one of the causative agents of spontaneous abortion in West Azerbijan Province, the northwest of Iran.

Abstract
Objective Reactivation of latent toxoplasmosis is the main cause of severe infection among immunocompromised patients, including patients with cancer. Hence, this study is aimed at screening the status of Toxoplasma gondii infection among breast cancer patients by serological and molecular methods and determining their associated risk factors in Jahrom County, Fars Province, south of Iran. Methods One hundred and seven women with breast cancer (aged 34 to 80 years) were screened for anti-T. gondii antibodies (IgG and IgM) during 2019-2020. A questionnaire regarding demographic factors was filled out by participants. Molecular detection was performed by polymerase chain reaction (PCR) using the primer pair targeting the repetitive element (RE) gene of T. gondii. The risk factors and demographic data were analyzed by SPSS software (ver. 20, Chicago, IL, USA) using the Chi-squared test. Results Anti-T. gondii IgG was detected in 45.8% (49/107) of the patients, which indicates latent infection, but anti-T. gondii IgM and PCR were negative in all samples. Demographic factors revealed a statistically significant increased T. gondii seropositivity among nonmenopause cancer patients (P < 0.0005), patients without previous breast cancer (P = 0.0001), and human epidermal growth factor receptor 2- (HER2-) negative patients (P = 0.00002). As such, patients with a history of previous abortions and who were at stages II, III, and IIII of cancer had higher seropositivity rates than patients without a history of previous abortions or who were at stage I cancer, but the statistical analysis was not significant. We did not find a statistically significant association between T. gondii seropositivity and other risk factors of toxoplasmosis (e.g., education level, type of water source, washing raw fruits and vegetables, consumption of raw or undercooked meat, and contact with soil, cats, and domestic animal). Conclusion A high seroprevalence rate of latent T. gondii infection was detected among patients with breast cancer; hence, these patients may be at high risk for reactivation of latent infection. Screening of T. gondii infection is recommended to detect active infection among patients with malignancies.

BENDER RA, AKBULAK R, SENGUL A. Can asymptomatic SARS-CoV-2 infection cause spontaneous abortion? JOURNAL OF HEALTH SCIENCES AND MEDICINE 2023.

Abstract
Aim: The probability of spontaneous abortion is known to increase (15%) in the pregnant women who develop symptomatic and even “Severe Acute Respiratory Syndrome (SARS)” due to maternal infections. It is known that the SARS-CoV-2 virus, one of these infectious agents, enters host cells by binding to angiotensin-converting enzyme 2 (ACE2). New literature data have shown the increased ACE2 receptor in the endometrium during the decidualization phase and the ability of SARS-CoV-2 to enter endometrial stromal cells through ACE2 proteins. This shows that the COVID-19 infection can cause many pathologies such as early pregnancy loss. The aim of this study is to investigate the effects of SARS-CoV-2 virus which are positive in the uterine samples on pregnancy loss.
Material and Method: 13 women who had first trimester pregnancy loss were included in this cross-sectional study. None of these pregnant women had any known symptoms of SARS-CoV-2 infection. SARS-CoV-2 infection was screened in uterus and naso-oropharynx samples by real-time polymerase chain reaction (RT-PCR) test in these pregnant women. Women with positive RT-PCR results will be evaluated for pneumonia by lung tomography. It is planned to evaluate the sample taken from the naso-oropharynx in the partners of these women for SARS-CoV-2 infection by RT-PCR. In addition, in positive cases, RT-PCR was planned from the uterus and naso-oropharynx samples at 7-day intervals until the case turned negative.
Results: RT-PCR test for SARS-CoV-2 was positive only in a sample taken from the uterus of one woman (7.6%). The naso-oropharyngeal sample of the same patient was negative, and the patient had no symptoms of COVID-19. No COVID-19-related lesion was observed in the lung tomography of this patient. The results of the RT-PCR test performed 7 days later with samples taken from the uterus and naso-pharynx were also negative. After the patient's positive RT-PCR result, a naso-oropharyngeal sample was taken from his partner. The RT-PCR test result for SARS-CoV-2 in the patient's partner was negative.
Conclusion: The fact that the SARS-CoV-2 virus was negative in the naso-oropharyngeal sample and positive in the uterine sample in a pregnant woman who had a miscarriage suggests that the endometrium may be an entry route for the virus. These data suggest that the virus can lead to adverse pregnancy outcomes, including early pregnancy loss, even without known symptoms. A large number of studies are needed to evaluate the effects of common viruses on pregnancy beyond the expected and defined symptoms.

Abstract
Congenital toxoplasmosis can cause severe consequences in the fetus, such as spontaneous abortion which is affected by parasite strain. Also, recent studies revealed the high genetic diversity of Toxoplasma gondii. This study aims to investigate the serological status of T. gondii in pregnant women, multilocus genotyping in aborted fetuses' tissue, and archived formalin-fixed paraffin-embedded placenta. This study was performed on 100 pregnant women with spontaneous abortion and their aborted fetuses, and 250 of the archived placentae in Iran. The blood and tissue were examined for seroprevalence and genotype determination of T. gondii using ELISA and multilocus nested-PCR-RFLP, respectively. Anti-T. gondii IgG and IgM were detected in 68 samples (68%) and 1 (1%) out of 100 serums. Toxoplasma DNA was identified in 1 (1%) aborted fetuses' tissue and 32 (12.8%) placenta samples. Overall, ten positive DNA samples were successfully genotyped, and five genotypes were recognized (ToxoDB#1, #2, #10, #27, and #48). The obtained results indicated congenital toxoplasmosis is a severe risk in this region. As type I is highly pathogen and can lead to severe complications, the prevention of the infection should be considered in seronegative pregnant women.

Spontaneous abortion among Toxoplasma gondii IgG seropositive women: Molecular detection, genotype identification, and serological assessment with conventional ELISA and avidity ELISA. J Obstet Gynaecol Res 2022; 48:2479-2485. [PMID: 35793814 DOI: 10.1111/jog.15349] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Revised: 06/14/2022] [Accepted: 06/21/2022] [Indexed: 11/26/2022]
Abstract
OBJECTIVES It has been generally believed that women who exposed to Toxoplasma gondii before pregnancy and have anti-T. gondii IgG antibody are immunized and their newborns will be protected from congenital infection. This study is aimed to investigate the role of T. gondii infection in spontaneous abortion through serological and molecular methods in southern Iran. STUDY DESIGN Blood samples were taken from 50 spontaneously aborted mothers and anti-T. gondii antibodies were assessed using conventional enzyme-linked immunosorbent assay (ELISA) and avidity ELISA methods. The placenta and blood samples of aborted women were used for detection of the parasite's DNA by polymerase chain reaction (PCR) method targeting the RE gene. The parasite genotypes were determined by PCR-restriction fragment length polymorphism (RFLP) method using SAG3 and GRA6 genes. RESULTS IgG antibody was detected in 28% (14/50) of mothers, but all samples were negative for IgM antibody. In the avidity ELISA test, 26% (13/50) of the samples had a high avidity index, suggesting chronic infection, while a low avidity index was detected in one case (2%), which suggests acute infection. The parasite's DNA was detected in 18% (9/50) and 14% (7/50) of blood and placenta samples, respectively. All DNA positive samples were IgG positive. All isolates were belonged to the T. gondii type III genotype. CONCLUSION The results suggest that T. gondii seropositive women are not protected from congenital transmission. However, the results should be interpreted cautiously until further studies will be confirmed these results.

Abstract
Background:
Toxoplasmosis which is caused by Toxoplasma gondii, is a widespread parasitic disease that affects approximately one-third of the world's population. Due to the significant side effects of anti-Toxoplasma drugs, it is necessary to acquire new drugs with low toxicity, high activity, cheaper and more effective.
Objective:
Earthworm has long been used as a therapeutic source of medicine in China and other parts of the Far East. Therefore, the purpose of the present study was to investigate of antiparasitic effects of Eisenia fetida extract against T. gondii in the Vero cell line.
Materials and Methods:
The effects of the extract on the parasite, Vero cell, and the parasitized cells were estimated by MTT assay in vitro. Apoptosis was also measured by flow cytometer in three groups of extract-treated parasites, extract-treated Vero cells, and extract-treated parasitic Vero cells, respectively.
Results:
The inhibitory effect of E. fetida extract and sulfadiazine was more than 85% and 65% on the parasite, respectively. Intracellular multiplication of the parasite in Vero cells during the 3 hours test showed a significant decrease compared to the 1 hour test (p<0.05). Flow cytometric analysis showed that with increasing concentration of E. fetida, apoptosis increased significantly (p<0.05).
Conclusion:
The results showed that E. fetida extract in vitro could have a significant antiparasitic effect against T. gondii.

Abstract
Background Toxoplasma gondii (T. gondii) is one of the most common intracellular protozoan parasites, which can infect humans and a wide range of mammals and birds. The current study is aimed at investigating the occurrence of T. gondii infection in women with a history of abortion in Khuzestan, Iran. Materials and Methods A total of 480 women with an abortion history, as well as 200 pregnant women with a normal delivery, were examined in this study. The blood, placenta, and umbilical cord blood samples were assessed by the enzyme-linked immunosorbent assay (ELISA) and nested-polymerase chain reaction (PCR) assay. Results Based on the results of ELISA assay, the prevalence of toxoplasmosis was 30.83% in women with a history of abortion (25.62% with T. gondii IgG and 5.20% with T. gondii IgM). According to the IgG avidity test, 60.16% of IgG-positive samples showed high avidity, while 27.64% showed low avidity. On the other hand, the prevalence of toxoplasmosis in women with a normal delivery was 23% (21.5% with T. gondii IgG and 1.5% with T. gondii IgM). According to the IgG avidity test, 81.39% of these women showed high avidity, while only 4.65% showed low avidity. Based on the nested-PCR method, T. gondii DNA was detected in 14.18% of blood samples, 4.69% of placental samples, and 1.34% of umbilical cord samples, collected from 148 seropositive women with a history of abortion. Besides, using this method, the parasite DNA was identified in 4.34% of blood samples, collected from 46 seropositive women with a normal delivery, but not in any of the umbilical cord or placenta samples. Conclusion The present results showed that T. gondii infection contributes to abortion in Khuzestan Province, Iran. Therefore, it is essential to investigate toxoplasmosis in pregnant women, especially in those who are seronegative, using molecular and serological methods and inform them about their disease and the associated risks.

Abstract
Toxoplasma gondii (T. gondii) is an intracellular protozoan that infects the fetus through the placenta and leads to severe complications in the fetus. One of the complications of congenital toxoplasmosis is spontaneous abortion. The prevalence of toxoplasmosis infection was investigated among spontaneously aborted fetuses (SAFs), and the genotypes of parasite isolates were determined in the present study. Placentas from 330 samples of SAFs were collected in Jahrom (Fars province) from February to September 2018. DNA was extracted from each placental tissue. The T. gondii infection was detected using nested polymerase chain reaction (Nested-PCR) assay based on a 529 bp repeat element (RE) gene. Afterward, Toxoplasma was genotyped using PCR-restriction fragment length polymorphism (PCR-RFLP) based on the GRA6 gene. The frequency of T. gondii infection was found to be 14.5% (48 out of 330 samples). Genotyping of nine T. gondii isolates revealed that all belonged to genotype II. Statistically, the prevalence of T. gondii infection was significantly correlated with the education levels of the mothers and the age of the fetus (P < 0.05). The lowest prevalence of Toxoplasma infection belonged to mothers with university education and the highest frequency of infection was observed among the fetuses in the age group of 8-9 weeks. The findings of the present study suggest a significant role for toxoplasmosis in SAFs in Jahrom city.

Toxoplasma gondii is one of the most common meat-born zoonoses that infect all warm-blooded animals and humans. Sheep (Ovis aries) is one of the main reservoirs of T. gondii worldwide, and the infections induce various sequels, such as abortion and stillbirth. The present study aimed to identify the effects of humidity on the prevalence of T. gondii in sheep in high- and low-humidity regions. Heart samples from 200 slaughtered sheep (140 samples from a high-humidity region and 60 samples from a low-humidity region) were collected from Hormozgan Province (south of Iran). The samples were tested by nested PCR targeting the RE gene. Genotyping was performed by the PCR-RFLP method using the SAG3 and GRA6 genes. Some isolates were sequenced and recorded in the GenBank. T. gondii DNA was detected in 10.71 percent of the samples from the highly humid region, whereas no positive samples were detected in the low-humidity region. Genotyping revealed that all isolates belonged to the T. gondii type III genotype. Our study indicated that humidity is an important factor for the prevalence of T. gondii in sheep. Additionally, our study also showed the dominance of type III strain of T. gondii in sheep in the south of Iran.

Abstract
Toxoplasmosis is one of the most common parasitic infections in humans, which is caused by Toxoplasma gondii. It is usually asymptomatic but primary infection in a pregnant woman can cause severe consequences in the fetus such as miscarriage. This study aimed to estimate the global prevalence of T. gondii infection in women with spontaneous abortion. It also evaluates the possible relationship between recent Toxoplasma infection and miscarriage. Five electronic databases were reviewed. We used the random effects model and 95% confidence intervals(CI) to determine the overall prevalence and odds ratio (OR). Heterogeneity was calculated using Cochran's Q test and I2 statistic. The included studies were divided into three sub-groups based on antibody class against T. gondii and the existence of parasite DNA. Based on PCR, the pooled random-effects estimates that the prevalence of T. gondii infection in women with abortion was 10% (95% CI 7-14%). The pooled random effect favored a statistically significant increased risk of latent Toxoplasma infection [OR = 1.84; 95% CI: 1.41-2.40, P < 0.001] and recent infection [OR = 3.72; 95% CI: 2.21-6.26, P < 0.001] in women with spontaneous abortions. In recent infections, significant pooled ORs of positive association were observed in women with miscarriage [OR = 4.2; 95% CI: 2.04-8.85; χ2 = 17.2; I2 = 42.0%, P = 0.07]. This study demonstrates that recent T. gondii infection is associated with an elevated risk of spontaneous abortion. Further studies concerning all risk factors related to toxoplasmosis, and undertaking confirmatory tests at the time of abortion should be performed to investigate the impact of T. gondii infection and spontaneous abortion.

Abstract
Background This research was aimed at evaluating the seroprevalence of acute and chronic Toxoplasma gondii (T. gondii) infection in pregnant women and related risk factors in southwest Iran. Methods In this cross-sectional study, eighty-eight pregnant women were included from October 2019 to December 2019. The presence of anti-T. gondii IgM and IgG antibodies was measured using the enzyme-linked immunosorbent assay (ELISA). In addition, a questionnaire consisting of demographic information was completed for each subject. Results The overall seroprevalence of T. gondii infection was estimated to be 34.09% (30/88). Of these, 1 (1.13%) and 29 (32.95%) samples were found positive for IgM and IgG, respectively. Regarding the risk factors, the consumption of raw/undercooked meat (P value = 0.007) and history of abortion (P value = 0.017) were significantly associated with IgG seroprevalence in pregnant women. Conclusion The results showed that the pregnant women of southwest Iran might be moderately exposed to T. gondii. Since the risk of acute T. gondii infection in this susceptible group is very important, regular screening tests to diagnose the infection are recommended before pregnancy.

Abstract
Background Toxoplasmosis in pregnancy could induce miscarriage, congenital anomalies in foetuses and encephalitis in HIV-infected people. Hence, there is a need to determine the prevalence of toxoplasmosis in HIV-infected pregnant women to inform clinicians about the significance of maternal toxoplasmosis in antenatal care. Aim This study aimed to determine the seroprevalence of Toxoplasma gondii infection, associated CD4+ T-cell profile and sociodemographic risk factors among pregnant women with or without HIV infection attending the University of Abuja Teaching Hospital, Abuja, Nigeria. Methods This hospital-based cross-sectional study involved blood samples collected from 160 HIV-infected and 160 HIV-seronegative pregnant women. These samples were analysed for anti-T. gondii (IgG and IgM) and CD4+ T-cell count using ELISA and flow cytometry, respectively. Sociodemographic variables of participants were collected using structured questionnaires. Results The overall seroprevalence of anti-T. gondii IgG and IgM was 28.8% and 3.8%, respectively. The seroprevalence of anti-T. gondii IgG and IgM was 29.4% and 4.4%, respectively, among HIV-seropositive pregnant women and 28.1% and 3.1%, respectively, among HIV-seronegative women. There was no significant association between the seroprevalence of anti-T. gondii-IgG and anti-T. gondii-IgM with age, gestational age, education level, parity or place of residence of HIV-infected pregnant women (P > 0.05). However, there was significant association between the seroprevalence of anti-T. gondii-IgG (P = 0.03) and anti-T. gondii-IgM (P = 0.01) with education level. CD4+ T-cell count varied significantly between HIV-infected and HIV-uninfected pregnant women (P = 0.035). Conclusion In this study, the seroprevalence of anti-T. gondii IgG and IgM did not differ in HIV-seropositive or HIV-seronegative pregnant women. However, women with primary T. gondii and HIV coinfection had lower CD4+ T-cell count than those with toxoplasmosis monoinfection.

Abstract
BACKGROUND The secondary sex ratio can be affected by various factors such as stress, immunosuppression, and age of parents in addition to mother infectious disease (Maternal infections). Toxoplasmosis is one of the critical maternal parasitic infections during pregnancy. Besides the complications of the acute form of the disease, hormonal shifts, and even alterations in the secondary sex ratio can be induced by the manipulative activity of the chronic form of the disease. Therefore, this study aimed to evaluate the correlation between Toxoplasma gondii infection in mothers and neonate's gender. METHODS In this case-control study, 137 seropositive mothers to Anti-Toxoplasma IgG(case) was compared to 137 age-matched subject Toxoplasma-seronegative mothers(control) in terms of their neonate's gender. These individuals were randomly selected based on exclusions and inclusions criteria of the study from among 2014 mothers who had been tested for Toxoplasma infection during pregnancy from 2015 to 2018 in Shiraz, Iran. RESULTS From a total of 2014 studied pregnant mothers, 326 (16.2%) mothers were seropositive to anti-Toxoplasma IgG, and 1688 (83.8%) were negative for IgG. It was found that the numbers of female and male neonates were 136 (45.48%) and 163 (54.51%) in the control group whereas, they were 165 (49.84%) and 166 (50.15%) in the case group, respectively. The sex ratio was 1.006:1 in Toxoplasma-seropositive and 1.2:1 in Toxoplasma-seronegative mothers. The number of male and females offsprings indicated a significant difference in Toxoplasma-seronegative mothers (54.5%, p = .015). Moreover, comparing the number of males and females between the two randomly selected groups showed that female gender is significantly more than male gender in seropositive mothers to Toxoplasma (54.8%, p = .014), which means that of 301 females, 165 offspring were born to seropositive mothers. No significant difference was observed for the sex ratio of aborted fetuses between groups. However, in the Toxoplasma-seropositive group, the sex ratio of aborted fetuses showed that the aborted male fetuses were significantly higher in number. (31 male vs 13 female, p < .001). CONCLUSION Comprehensively, a significant relationship was found between chronic Toxoplasma infection and secondary sex ratio. However, it is suggested that this relationship be investigated in further studies as well as an animal study.

Abstract
BACKGROUND Toxoplasma gondii (T. gondii) is an intracellular pathogen that can lead to abortion in pregnant women infected with this parasite. Therefore, the present study aimed to estimate the global seroprevalence of anti-T. gondii antibodies in women who had spontaneous abortion based on the results of published articles and evaluate the relationship between seroprevalence of anti-T. gondii antibodies and abortion via a systematical review and meta-analysis. METHODS Different databases were searched in order to gain access to all studies on the seroprevalence of anti- T. gondii antibodies in women who had spontaneous abortion and association between seroprevalence of anti-T. gondii antibodies and abortion published up to April 25th, 2019. Odds ratio (OR) and the pooled rate seroprevalence of T. gondii with a 95% confidence interval (CI) were calculated using the random effects model. RESULTS In total, 8 cross-sectional studies conducted on 1275 women who had abortion in present pregnancy, 40 cross-sectional studies performed on 9122 women who had a history of abortion, and 60 articles (involving 35 cross-sectional studies including 4436 women who had spontaneous abortion as case and 10398 as control and 25 case-control studies entailing 4656 cases and 3178 controls) were included for the final analyses. The random-effects estimates of the prevalence of anti-T. gondii IgG antibody in women who had abortion in present pregnancy and women who had a history of abortion were 33% (95% CI: 17%-49%) and 43% (95% CI: 27%-60%), respectively. In addition, the pooled OR for anti-T. gondii IgG antibody in cross-sectional and case-control studies among women who had spontaneous abortion were 1.65 (95% CI: 1.31-2.09) and 2.26 (95% CI: 1.56-3.28), respectively. Also, statistical analysis showed that the pooled OR of the risk of anti-T. gondii IgM antibody 1.39 (95% CI: 0.61-3.15) in cross-sectional and 4.33 (95% CI: 2.42-7.76) in case-control studies. CONCLUSION Based on the results of the current study, T. gondii infection could be considered a potential risk factor for abortion. It is recommended to carry out further and more comprehensive investigations to determine the effect of T. gondii infection on abortion to prevent and control toxoplasmosis among pregnant women around the world.

Abstract
BACKGROUND Given the lack of routine screening and the high prevalence of toxoplasmosis in pregnant women in Iran, the current study aimed to find out the rate and features of Toxoplasma gondii infection in the spontaneously aborted human fetuses in Kohgiluyeh and Boyer-Ahmad Province, Southwestern Iran. METHODS This cross-sectional study was performed on 100 spontaneously aborted fetuses' tissues and their mother blood samples. The mothers' sera were evaluated for anti-Toxoplasma antibodies while their buffy coat and aborted fetuses tissues were evaluated for Toxoplasma DNA. PCR product at GRA6 locus was sequenced and phylogenetic analysis was done. Likewise, quantitative Real-Time PCR was performed to find out the parasite burdens in mothers buffy coat and fetuses tissues. RESULTS Using serological method, anti-Toxoplasma IgG and IgM antibodies were detected in 7 (7%) and 3 (3%) out of 100 sera from women with spontaneous abortion. Real-time PCR method detected T. gondii DNA in the buffy coat of one seronegative and 2 (out of 3) IgM seropositive cases. None of the samples from aborted fetuses were infected with T. gondii. BLAST and phylogenetic analysis showed that the sequenced isolates belonged to type I of T. gondii and two identified T. gondii isolates were taxonomically grouped into one clade. CONCLUSION Our findings revealed type I genotype of T. gondii in two mothers with spontaneous abortion, without fetus involvement. It is necessary to examine more aborted fetuses' samples from different geographical areas to determine the association between Toxoplasma genotype and abortion.

Abstract
Background Toxoplasma gondii is one of the major causes of abortion in pregnant women. Most cases of abortion occur in the acute phase of infection and early pregnancy. The purpose of this study was to investigate the association between spontaneous abortion and seropositive status of toxoplasmosis in women with first-time spontaneous abortion. Materials and Methods This research is a case-control study on 240 serum samples from women experiencing spontaneous abortion for the first time as the case group, and 240 serum samples from women who had a normal delivery with no history of abortion as the control group. The level of anti-Toxoplasma gondii IgM and IgG antibodies were assessed in serum samples using ELISA. To separate the acute and chronic infections, all IgM-positive samples in both groups and IgG-positive samples of the case group were examined using IgG avidity. Results The toxoplasmosis IgM antibody was detected in 3.3% (8/240) of the case group and 0.4% (1/240) of the control group, which was a statistically significant difference between the two groups [P=0.019, odds ratio (OR)=10.266]. Of all samples 47.5% and 46.3% of the case and control groups were positive for toxoplasmosis IgG antibody, respectively. Seven out of 8 (87.5%) IgM-positive serum samples from the case group had low IgG avidity, indicating acute infections, whereas all IgG-positive sera and 1 IgM-positive serum, which was related to the control group, showed a high IgG avidity, indicating chronic infections. Conclusion Maternal acute toxoplasmosis during pregnancy is raised as one of the factors that increase the chance of spontaneous abortion. The necessary health training, especially on the parasite transmission ways to women before marriage, as well as the serological test in women before and during pregnancy is recommended. Polymerase chain reaction (PCR) and IgG avidity assays should be performed in the medical diagnostic laboratories for accurate distinguishing of the initial infection of toxoplasmosis in the pregnant women.

Abstract
Toxoplasmosis is a serious zoonotic disease that can lead to abortion and congenital disorders and has a widespread global distribution in humans and animals. The objective of this review was to investigate the incidence of toxoplasmosis in Iranian neonates in order to obtain a comprehensive assessment of the overall situation of the disease for use in developing future interventions. Original studies investigating the incidence of Toxoplasma gondii infections in Iranian neonates were systematically searched in a number of English-language and Persian-language electronic databases. The search process resulted in the inclusion of a total of 11 studies in the systematic review, 10 of which were entered into the meta-analysis. The reviewed articles included 2,230 Iranian neonates investigated through January 1, 2018. Based on the retrieved studies, the overall weighted incidence rates of toxoplasmosis in the Iranian neonatal population and neonates with suspected congenital toxoplasmosis were estimated to be 0.64% (95% confidence interval [CI], 0.31 to 1.09) and 4.10% (95% CI, 2.68 to 5.77), respectively, using a fixed-effects model. The findings of the reviewed studies demonstrate that the incidence of toxoplasmosis is high in Iranian neonates. Accordingly, it can be concluded that toxoplasmosis is a serious public health concern that has been ignored by the Ministry of Health. Therefore, it is essential to perform further studies, in addition to implementing screening and detection programs, using standardized methods to estimate the incidence of toxoplasmosis in Iran and to determine its associated risk factors.

Factors Associated With Toxoplasma gondii IgG and IgM Antibodies, and Placental Histopathological Changes Among Women With Spontaneous Abortion in Mwanza City, Tanzania. East Afr Health Res J 2017; 1:86-94. [PMID: 34308163 PMCID: PMC8279292 DOI: 10.24248/eahrj-d-16-00408] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2016] [Accepted: 07/25/2017] [Indexed: 11/20/2022] Open
Abstract
Background: Toxoplasma gondii infection in early pregnancy has been associated with significant adverse pregnancy outcomes. Despite being common in the city of Mwanza, its association with spontaneous abortion has never been studied. Here, we report the IgG and IgM seropositivity and histopathological changes of toxoplasmosis among women with spontaneous abortion. Methods: A total of 260 women with spontaneous abortion were enrolled between November 2015 and April 2016 from 4 hospitals in Mwanza city. Specific T. gondii IgG and IgM antibodies were detected from sera by indirect enzyme-linked immunosorbent assay (ELISA) while the conceptus tissues were stained with haematoxylin and eosin to demonstrate histo-pathological changes. Data were analysed by using Stata version 13. Results: The mean age of the enrolled women was 2665.9 years. The seropositivity of IgG and IgM antibodies were 144/260 (55.4%; 95% confidence interval [CI], 49–61) and 6/260 (2.3%; 95% CI, 3–8), respectively. IgG seropositivity was significantly high among women in the first trimester (59.1% vs.43.5%; P=.03). Only low gestation age (odds ratio [OR] 1.11; 95% CI, 1.02–1.20; P=.02) and keeping a cat (OR 11.80; 95% CI, 1.32–10.5; P=.03) independently predicted IgG and IgM seropositivity, respectively. Presence of inflammation (OR 1.95; 95% CI, 1.05–3.64; P=.03), calcification (OR 3.28; 95% CI, 1.01–10.63; P=.04), necrosis (OR 2.86; 95% CI, 1.39–5.89; P=.04), and lymphocyte infiltrations (OR 2.24; 95% CI, 1.17–4.24; P=.01) were significantly associated with T. gondii IgG seropositivity. Conclusion: Almost half of women with spontaneous abortion in the city of Mwanza have specific T. gondii IgG antibodies. Placental histopathological changes suggestive of toxoplasmosis were significantly found among IgG seropositive women. This calls for the need to screen these women during antenatal visits in order to institute appropriate measures, such as treatment and counselling, to prevent complications associated T. gondii infection.

Molecular Detection and Genotypic Characterization of Toxoplasma gondii in Paraffin-Embedded Fetoplacental Tissues of Women with Recurrent Spontaneous Abortion. INTERNATIONAL JOURNAL OF FERTILITY & STERILITY 2016; 10:327-336. [PMID: 28042412 PMCID: PMC5135736 DOI: 10.22074/ijfs.2016.4569] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/07/2015] [Accepted: 07/11/2016] [Indexed: 01/24/2023]
Abstract
Background Congenital toxoplasmosis is an important cause of spontaneous abortion
worldwide. However, there is limited information on detection and genotypic characterization of Toxoplasma gondii (T. gondii) in women with recurrent spontaneous abortion
(RSA). The aim of this study is the molecular detection and genotypic characterization of
T. gondii in formalin-fixed, paraffin-embedded fetoplacental tissues (FFPTs) of women
with RSA that have referred to the Avicenna Research Institute in Tehran, Iran. Materials and Methods This experimental research was undertaken on 210 FFPTs of
women with RSA. The information of the patients was collected from the archives of
Avicenna Research Institute in Tehran, Iran. After DNA extraction, the presence of T.
gondii was examined by nested polymerase chain reaction targeting the GRA6 gene. Genotyping was performed on positive samples using polymerase chain reaction-restriction
fragment length polymorphism (PCR-RFLP) that targeted the GRA6 and SAG3 genes.
Sequencing was conducted on two GRA6 positive samples. Results T. gondii DNA was detected in 3.8% (8/210) of the samples. Genotyping showed
that all positive samples belonged to type III of the T. gondii genotype. Sequencing two
genomic DNAs of the GRA6 gene revealed 99% similarity with each other and 99-100%
similarity with T. gondii sequences deposited in GenBank. There were six patients with
histories of more than three abortions; one patient had a healthy girl and another patient
had two previous abortions. Abortions occurred in the first trimester of pregnancy in seven
patients and in the second trimester of pregnancy in one patient. Conclusion The results of this study have indicated that genotype III is the predominant
type of T. gondii in women with RSA in Tehran, Iran. Also, our findings suggest that
toxoplasmosis may play a role in the pathogenesis of RSA. However, further studies are
needed to elucidate a clear relationship between T. gondii infection and RSA.

Congenit Anom (Kyoto) 2016; 56:73-8. [PMID: 26499091 DOI: 10.1111/cga.12138] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2015] [Accepted: 09/18/2015] [Indexed: 12/30/2022]
Abstract
ToRCH infections (toxoplasmosis, rubella, cytomegalovirus and Herpes simplex virus) have long been known to be associated with bad obstetric outcomes. However, little information is available about the impact of ToRCH co-infections on the outcome of pregnancy. Hence, we tested the IgG and IgM antibodies to Toxoplasma gondii, Rubella, Cytomegalovirus and Herpes Simplex Virus among 81 pregnant women with abortion (case group) and 98 pregnant women with normal delivery (control group). In the single-infection model, only CMV-IgM seropositivity was significantly increased in case than control group (25.9% in case and 12.2 % in control, OR = 2.5, P = 0.019). In the co-infection model, 14 patterns were recognized, but two patterns were significantly increased in the case than the control group. Co-infection of T. gondii IgG + CMV IgM was 9.1-fold increased in the case than the control group (8.6% in the case and 1% in control, OR = 9.1; P = 0.024). Also, co-infection of T. gondii IgG + HSV IgG + CMV IgM was 7.7-fold increased in case than the control group (7.4% in case and 1 % in control, OR = 7.7; P = 0.04). Although the OR of other co-infections was higher in the case than the control group, the difference was not statistically significant. These findings indicate that ToRCH co-infections are associated with increased risk of abortion than single infection. Hence, the rates of co-infections should be considered in prenatal screening of ToRCH infections.

Abstract
Through a cross-sectional study design, 150 women attending public health centers with a history of stillbirths were examined for anti-Toxoplasma gondii IgG and IgM antibodies in Durango City, Mexico. Bivariate and multivariate analyses were used to assess the association of T. gondii seropositivity with the characteristics of the women with stillbirth history. Of the 150 women (mean age: 32.09 ± 9.16 years) studied, 14 (9.3%) had anti-T. gondii IgG antibodies and six (42.9%) of them were also positive for anti-T. gondii IgM antibodies. Multivariate analysis showed that T. gondii seropositivity was associated with high frequency (4–7 days a week) of eating meat (OR = 5.52; 95% CI: 1.48–20.59; P = 0.01), history of lymphadenopathy (OR = 4.52; 95% CI: 1.14–17.82; P = 0.03), and history of surgery (OR = 8.68; 95% CI: 1.04–72.15; P = 0.04). This is the first study on the seroepidemiology of T. gondii infection in women with a history of stillbirths in Mexico. The association of T. gondii exposure with a history of surgery warrants for further research. Risk factors for T. gondii infection found in the present survey may help to design optimal educational programs to avoid T. gondii infection.
