Acute Toxoplasmosis

Background: Toxoplasmosis is a globally distributed parasitic disease. The present study aimed to estimate the prevalence and geographic distribution of toxoplasmosis as well as determine the percentage of toxoplasmosis-associated IgM and IgG seropositivity among different age groups. In addition, it aimed to estimate the proportion of toxoplasma IgM seropositivity among pregnancy trimesters. Methods: A total of 500 pregnant women were included in this study. From each participant, a 5-ml venous blood sample was collected and centrifuged to obtain serum that was tested for Toxoplasma gondii IgM and IgG antibodies using immunochromatographic testing and ELISA. Results: The overall seroprevalence of toxoplasmosis was 24.8%. Out of the total of 500 participants, only 8% had a serological marker of acute toxoplasmosis). There is a statistically significant difference in the seroprevalence of disease among the study areas. Amongst positive cases of every trimester, 54.34% of first trimester positive cases had a serologic marker for acute toxoplasmosis.  Conclusions: In this study, there is a high prevalence of toxoplasmosis. Therefore, it is necessary to test every pregnant woman for toxoplasmosis and distinguish the type of infection, as well as the conduction of public health education programs to generate the awareness.

Acute Toxoplasmosis

Background: Toxoplasmosis is a globally distributed parasitic disease. The present study aimed to estimate the prevalence and geographic distribution of toxoplasmosis, as well assess the risk of animal contact in disease development and determine the percentage of toxoplasmois-associated IgM and IgG seropositivity among different age groups. In addition, it aimed to estimate the proportion of toxoplasma IgM seropositivity among pregnancy trimesters. Methods: A total of 500 pregnant women were included in this study. From each participant, a 5-ml venous blood sample was collected and centrifuged to obtain serum that was tested for Toxoplasma gondii IgM and IgG antibodies using immunochromatographic testing and ELISA. Results: The overall seroprevalence of toxoplasmosis was 24.8%, with rates of acute infection of 8%. Among positive cases in every trimester, 54.34% of first trimester positive cases had a serologic marker of acute toxoplasmosis. Out of the 40 pregnant women with previous history of cow/buffalo contact and toxoplasmosis, 40% were seropositive for toxoplasma IgM; and out of 30 women with prior history of dog contact, 16.66% had serological marker of acute toxoplasmosis. Conclusions: In this study, there is a high prevalence of toxoplasmosis and contact with domestic animals is a risk factor for this illness. Therefore, it is necessary to test every pregnant women for toxoplasmosis and distinguish the type of infection, as well as the conduction of public health education programs to generate the awareness.

Background: Toxoplasma Gondii, Rubella, and Cytomegalovirus (CMV) are the most common causes of congenital infections worldwide. There is not a consensus on these infectious agents should be screened during pregnancy. The aim of this study is to determine the prevalence of toxoplasma, rubella, and CMV infections in order to know the need for antenatal screening.Methods: This retrospective cross-sectional study was performed on 1309 ambulatory pregnant patients who applied to the obstetric clinic of a university hospital between October 2016 and April 2018. Documents of patients in the first trimester were reviewed and serologic data of Toxoplasma gondii, CMV, Rubella infections were retrieved from the computer database.Results: Of 1309 pregnant women, positivity for anti-Toxoplasma IgG antibody was 352(26.9%), while 17(1.3%) of the subjects tested were positive for the anti-Toxoplasma IgM antibody. These positivities of the pregnant women for anti-Rubella IgG and IgM were 1147(87.6%) and (0.1%), respectively. These positivities of the pregnant women for anti-CMV IgG and IgM were 1163(88.8%) and 17(1.3%), respectively.Conclusions: We detected high rates of immunity against Rubella and CMV but low rates of immunity against Toxoplasma in this retrospective cohort of pregnant women. Due to high rates of seropositivity against Rubella and CMV, routine nationwide screening may not be necessary.

Anti-SARS-CoV-2 spike RBD (receptor-binding domain) IgG antibody levels were monitored in 1643 volunteer healthcare workers of Eginition, Evangelismos, and Konstantopoulio General Hospitals (Athens, Greece), who underwent vaccination with two doses of COVID-19 BNT162b2 mRNA vaccine (Pfizer) and had no history of SARS-CoV-2 infection. Venous blood was collected 20–30 days after the second vaccine dose and anti-RBD IgG levels were determined using CMIA SARS-CoV-2 IgG II Quant (Abbott) on ARCHITECT i System or ADVIA Centaur SARS-CoV-2 IgG (Siemens) on Centaur XP platform. From the total population of 1643 vaccinees (533 M/1110 F; median age = 49; interquartile range-IQR = 40–56), 1636 (99.6%) had anti-SARS-CoV-2 IgG titers above the positivity threshold of the assay used. One-Way ANOVA Kruskal-Wallis H test showed a statistically significant difference in the median of antibody titers between the different age groups (p < 0.0001). Consistently, Spearman’s correlation coefficient (r) for IgGs and age as continuous variables was −0.2380 (p = 1.98 × 10−17). Moreover, antibody titers were slightly higher by 1.2-mean fold (p = 3 × 10−6) in the total female population of the three hospitals (median = 1594; IQR = 875–2584) as compared to males (median = 1292; IQR = 671.9–2188). The present study supports that BNT162b2 vaccine is particularly effective in producing high anti-SARS-CoV-2 IgG levels in healthy individuals, and this humoral response is age- and gender-dependent.

Abstract Background Exposure to Toxoplasma gondii infection is prevalent in up to 90% of the world’s population. Severe infections can be fatal and deforming in neonates. Cats serve as reservoirs for T. gondii infections. Even though many Ghanaians have cats as pets in their homes only few studies have been undertaken to assess the prevalence of the disease in Ghana. The objective of the study was to determine the seroprevalence of T. gondii infection and its associated risk factors among pregnant women seeking antenatal care at the Goaso Municipal Hospital, in Asunafo North District of the Ahafo Region and the St. Michael’s Catholic Mission Hospital in the Bosomtwe District in the Ashanti Region of Ghana. Methods A cross-sectional study involving 266 (146 from Asunafo North District and 120 from Bosomtwe District) pregnant women who consented to participate in the study was undertaken. To gather information on associated risk factors, structured questionnaire was administered to the participants. In addition, 3 mls of venous blood was collected from each participant for anti-T. gondii IgG and anti-T. gondii IgM antibody analyses using ELISA. Results A total of 64.3% (171/266) of the study participant were positive for anti-T. gondii IgG and 26.3% (70/266) were positive for anti-T. gondii IgM antibodies. This signifies that 64.3% of the study population have been exposed to the infection and 26.3% were actively infected. There were no differences (P=0.383) between the overall T. gondii seroprevalences in the two Districts. There was a significant difference between antibody concentration levels and age in the Bosomtwe District in Ashanti Region. No association (OR<1) was found between the seroprevalences and the suspected risk factors assessed in this study. Conclusion The study showed that the seroprevalence of T. gondii among pregnant women visiting the two health facilities in the two Regions was higher compared to the 30%-65% reported as the global population infection status. This study provides baseline data for future studies in the other Districts and Regions in the country to ascertain the overall seroprevalence in Ghana.

Iron deficiency, with or without anemia, is common in pregnant women and more than half of the anemia’s in the world are due to the deficiency of iron in the serum. The aims of this study were to determine the percentage and level of serum iron among iron supplemented pregnant women in different trimesters and in different age groups among supplemented pregnant women in Sulaimani city. This study was carried out in the private clinic in the Sulaimani city-Kurdistan Region of Iraq. The pregnant women were participated and enrolled between the first of December 2018 and first of December 2019. Two hundred and seventy-five healthy and iron supplemented pregnant women were selected randomly and the questionnaire form, which contains information about age of mothers and their gestational age, was filled and serum iron level was measured by COBAS C111 analyzer. The results of this study found that the percentage of iron deficiency among participants was high 33%, 45%, and 52.6 % in the first trimester in different age groups <25, 25–35, and above 35 years old, respectively. However, in the third trimesters decreased to 12.5%, 7.1%, and 3.7% in <25, 25–35, and above 35 years old, respectively. Regarding serum iron levels, the present study found that there were significant differences between ages 25 and 35 with age <25 years. However, there was no significant difference between first, second, and third trimesters. This study concludes that the percentage of iron deficiency among supplemented pregnant women was high compared to other cities or other countries. Pregnant women who their ages <25 are at risk of serum iron deficiency. On the other hand, pregnancy trimesters had no effects on the serum iron level among supplemented pregnant women.

Toxoplasmosis during pregnancy has an adverse effect on pregnant women, fetus and neonatal. The infection is generally asymptomatic but can cause severe effect on the fetus and immunocompromised women. Control study conducted on 77 pregnant women categorized according to the risk factors influencing toxoplasmosis infection. Specific anti Toxoplasma gondii IgG and IgM were evaluated using Enzyme-linked immunosorbent assay (ELISA) test kits. Among 77 pregnant women, (57.1%) women had toxoplasmosis, seropositive for latent infection with specific Toxoplasma gondii immunoglobulin G (IgG) antibodies were (54.54 %), whereas acute infection immunoglobulin M (IgM) were only in (2.59 %) cases. The seroprevalence of Toxoplasma was higher in older pregnant women (> 60%) than younger ones (<50%). The specific IgG antibody was higher in pregnant women working in farms (65.7 vs 45.23; P=0.053). Also, the seropositive IgG antibody was low in the first trimester and high in rural areas. Pregnant women need to educate more about toxoplasmosis and prevention to exposure in order to reduce the risk of congenital toxoplasmosis.

OBJECTIVE To analyze the prevalence of IgG antibodies to Toxoplasma gondii in patients infected with HIV/AIDS and the association of demographic and social variables. METHODS Descriptive cross-sectional study that included the analysis of sociodemographic data and laboratory findings of 200 patients infected with HIV/AIDS treated in a laboratory unit in Maputo, Mozambique, in 2010. Individual data for all participants were collected with a self-administered questionnaire. Plasma samples were tested for IgG testing of anti- T. gondii using hemagglutination for the analysis of antibodies. RESULTS The seroprevalence of IgG anti- T. gondii was 46.0% (95%CI 39.2;52.9), 39.3% (95%CI 29.5;50.0) in men and 50.9% (95%CI 41.9;59.8) in women, with no difference between sex (OR 1.30; 95%CI 0.95;1.77; p = 0.12). Ages ranged from 10 to 60 years, with a higher prevalence of infection in older age groups, but with no significant difference between them. Regularly consuming cattle meat (OR 1.74; 95%CI 1.04;2.89, p = 0.05), breeding cats/dogs (OR 6.18; 95%CI 3.60;10.62, p < 0.000) and having regular contact with soil (OR 3.38; 95%CI 2.19;5.21; p < 0.000) were significantly associated with risk of latent infection. CONCLUSIONS Toxoplasmosis is an infection with high prevalence in Mozambique. Cultural and behavioral aspects increase the risk. Toxoplasmosis can be responsible in our environment by the great burden of morbidity and mortality associated with meningoencephalic injuries in patients with HIV/AIDS.

BACKGROUND Seroprevalence of IgG antibodies against SARS-CoV-2 is an important tool to estimate the true extent of infection in a population. However, seroprevalence studies have been scarce in South East Asia including India, which, as of now, carries the third largest burden of confirmed cases in the world. The present study aimed to estimate the seroprevalence of anti-SARS-CoV-2 IgG antibody among hospitalized patients at one of the largest government hospital in India OBJECTIVE The primary objective of this study is to estimate the seroprevalence of SARS-CoV-2 antibody among patients admitted to the Medicine ward and ICU METHODS This cross-sectional study, conducted at a tertiary care hospital in North India, recruited consecutive patients who were negative for SARS-CoV-2 by RT-PCR or CB-NAAT. Anti-SARS-CoV-2 IgG antibody levels targeting recombinant spike receptor-binding domain (RBD) protein of SARS CoV-2 were estimated in serum sample by the ELISA method RESULTS A total of 212 hospitalized patients were recruited in the study with mean age (±SD) of 41.2 (±15.4) years and 55% male population. Positive serology against SARS CoV-2 was detected in 19.8%patients(95% CI 14.7-25.8). Residency in Delhi conferred a higher frequency of seropositivity 26.5% (95% CI 19.3-34.7) as compared to that of other states 8% (95% CI 3.0-16.4) with p-value 0.001. No particular age groups or socio-economic strata showed a higher proportion of seropositivity CONCLUSIONS Around, one-fifth of hospitalized patients, who were not diagnosed with COVID-19 before, demonstrated seropositivity against SARS-CoV-2. While there was no significant difference in the different age groups and socio-economic classes; residence in Delhi was associated with increased risk (relative risk of 3.62, 95% CI 1.59-8.21)

Objective: In our study, the results of oral glucose tolerance test (OGTT) and other hemogram parameters of pregnant women with and without gestational diabetes mellitus (GDM) were compared. The aim of our study is to investigate the benefit of these parameters in predicting GDM risk. Material and Method: The study was planned as a descriptive, retrospective and cross-sectional study. It was included 218 pregnant women who applied to the Gynecology and Obstetrics Clinic of Amasya Sabuncuoğlu Şerefeddin Training and Research Hospital between January 01, 2019 and January 31, 2020. It was examined complete blood count parameters, ultrasound findings, complete urinalysis, first trimester blood glucose, body mass index, age, and gravide parameters the patients we included in the study. The results were analyzed retrospectively and was evaluated the statistical significance relationship with gestational diabetes. Results: There was no statistically significant difference in age, body mass index (BMI), obesity status and number of gravida between the pregnant women who were examined and those without GDM (p> 0.05). The hemoglobin, platelet count, mean platelet volume (MPV), mean corpuscular volume (MCV), mean corpuscular hemoglobine (MCH), and mean corpuscular hemoglobin concentration (MCHC) values, and neutrophil, lymphocyte, monocyte and basophil counts, urine density and femur length were statistically significant. There was no difference (p> 0.05). No statistically significant difference was found in terms of neutrophile lymphocyte ratio (NLR), neutrophile monocyte ratio (NMR), platelet lymphocyte ratio (PLR), monocyte eosinophil ratio (MER), platelet MPV ratio (PMPVR), and platelet neutrophile ratio (PNR) values (p> 0.05) Conclusion: HbA1c, hematocrit and blood glucose in the first trimester may be predictors of GDM. In addition, we think that further studies are needed in a prospective design in more patients in terms of others parameters.
