ABSTRACT

Background: Toxoplasmosis had a remarked role in disturbing pregnancy in women by abortions and congenital abnormalities outcome .Vitamin D deficiency had a role in bone fragility, osteoporosis, exposing women to fractures as well as to bone deformities in newborns. Objective: To assess the relationship between toxoplasmosis seropositivity and vitamin D abnormalities in sera of women in childbearing ages using ELISA and auto-analyzers. Methodology: A cross-sectional study was conducted by examining the sera of 153 women, who visited Azadi Teaching Hospital Gynecological and Obstetric Clinics. Their complaints involve signs of bad obstetric history (BOH) and bone disorders, versus to 46 women negative for (BOH). Their ages ranged from 15 to 50 years. The results: The overall rate of positive toxoplasmosis was 78.43% distributed into the following rates: 22.87%, 49.01%, and 13.07% for IgM, IgG, and IgM + IgG antibodies, P < 0.05. Whereas the examination of sera in the control group reveals only 14 sera positive for IgG Abs, the rate was 31.12%. Sera from women in the early childhood age bearing exerts high rates of T. gondii IgM than in sera of women aged over 46 years, P < 0.05. Non-animal contact women sera reveal higher rates of T. gondii Abs than in contact women. The relationship between toxoplasmosis, urinary tract infection (UTI) and arthritis was significant. Women with previous single abortion reveal high rates of toxoplasmosis compared to multi-abortion. The impact of toxoplasmosis concerning serum vitamin D3 levels denoted as vitamin D3 deficiency in both two groups. Conclusions: The rate of toxoplasmosis among childbearing age women was high, and the relationship between toxoplasmosis and vitamin D deficiency was significant. This finding is preliminary and prone women for getting osteoporosis.

1. Introduction

Since concerning ten years, a widespread vitamin D deficiency has grown in all Iraqi communities and in particular, in Kirkuk province among all peoples. According to available unpublished knowledge, the rate was high, particularly among women of different ages [1]. Vitamin D is a steroidal hormone whose primary function is calcium homeostasis, conserving bone, and keeps it healthy. Recently extensive researches indicate the significance of vitamin D on the far side, keeping bones healthy and robust; it has shown the connection between levels of vitamin D and cancer [2]. Deficiency or low level of vitamin D is correlative to 30% to 50% of rectal and colon cancer, breast cancer, and prostate [3].

In female reproduction, lack of vitamin D3 in an experiment done on mice showed defects in uteri development; thus, infertility shown because of incapacity to produce mature regular eggs [4]. In Saudia Arabia, a case-control study of women, disclosed that optimizing of serum vitamin D and calcium is crucial to stop sub-fertile women [4]. In Egypt, Sabry et al., 2013 in an exceedingly separate cohort of white and black females in North Africa regarding risk of female internal reproductive organ leiomyoma, they found a significant inverse association between the severity of fibroid among African-American females and low level of nutriment D [5].

During the fertile period, women may suffer from polycystic ovarian dysfunction (PCOS) and may associate with anovulation [6]. They recorded the frequency of low vitamin D levels among women with (PCOS) at a high ranged rate, and the rate was about 67% to 85% [7]. Vitamin D level below 20 ng/ml may exert some symptoms like Obesity, risk of cardiovascular disease, insulin resistance, menstrual irregularity, infertility, and hyper-androgenism [8] [9].

The two-primary potential importance of vitamin D involves immune modular and fetal immunologic response [10]. The associations between 25(OH) vitamin D and the first trimester of miscarriages are high, moderate within the second trimester. Contrary to the third trimester, this association becomes weak, suggesting vitamin D as a modifiable risk issue for miscarriage [11].

The impacts of the parasitic infections attributed to some factors, such as nutrition, immune status, amount of ingested parasite, parasite virulence, and location inside of the host. Tissue parasites had severe influences on the host, in particular, human beings; an example of that is a coccidian protozoan parasite “Toxoplasma gondii.” This parasite is cosmopolitan, that infect a cat, the final host, whereas most of the mammals are infected in nature through contamination by the different stages of this parasite [12]. Morphologically the stages involve two kinds of trophozoites, namely, tachyzoites (actively motile) and bradyzoites (sluggishly motile), tissue cysts (in the intermediate host mostly) and the oocysts (Immature when discharges and mature after 3 to 7 days in the environment) [13]. Transmission is by different modes such as water, raw milk, un-properly cooked meat, unwashed vegetables, blood donations, through medical tools, and mainly by Oocysts, which contains two sporocysts, each one contains four sporozoites [14] [15].

Clinically, the disease is self-limiting among immunocompetent called acquired toxoplasmosis, while in massive infection, the picture of the disease can involve: acute, sub-acute, and chronic stages [16]. The most dominant features are mimicking to febrile diseases like fever, malaise, fatigue, and sings of lymphadenopathy. The picture becomes more severe and life-threatening in immune-compromised and depleting diseases individuals [17]. The ability of the trophozoites contact fetus through the placenta, enable it to reach the fetus and cause the second picture “congenital toxoplasmosis” in women during gestational periods [18].

Compliance in women involves habitual, missed, or spontaneous abortions. Abortions can occur high in the first trimester and slightly at a low rate in the second trimester, while acquiescing the infection in the third trimester can give rises to definitive congenital abnormalities. The events of pathogenesis included: hydrocephalus, microcephaly, Chorio-retinitis, meningoencephalitis, potentially leading to death (stillbirth) [19]. Infants for infected mothers mainly when she acquires the infection in the third trimester, mostly accompanied by chorioretinitis, blindness, deafness, mental retardation, difficulties in motion, and epilepsy [20]. In males and unmarried girls, their sera reveal specific sufficient antibodies able to prevent subsequent infection with the same parasite (sterile immunity). In contrast, married women, s immune response most often associated with seroconversion due to reactivation of latent or chronic infections [21]. Furthermore, T-helper 1 and 2 lymphocytes have had an experimental role in eliminating the infection inter and extra-cellularly. Serology is the method of choice for the diagnosis of Toxoplasma gondii like ELISA, (Direct fluorescent assay (DFA), DAT (Direct agglutination test (DAT)), Rapid Lateral Immuno-chromatography assay (RILICA), and different types of PCR technology [22].

According to available data, in Iraq, information or researches regarding disorder of vitamin D 3 disorders, calcium, parathyroid hormone, inorganic phosphorous, and its relation to women toxoplasmosis is absent, so the current study was aimed at to achieve that in Kirkuk city using some serological and biochemical tests.

2. Materials and Methods

Period and place: The current study was carried on from 1th of December 2018 to 30 June 2019 in Azadi teaching Hospital and laboratories of the KirkukMedical College.

Study design and subjects: A cross-sectional was performed on two groups of women, first group women with Bad obstetric History (BOH) and signs of bone disorders. The second group of women has no BOH, their ages ranged from 15 years to over 46 years.

Exclusion criteria: Sera of women revealed positive for other etiological agents of BOH, like Cytomegalovirus, Rubella, and human Herpes simplex viruses were excluded and not enrolled in the study.

Ethical approval: The permission for carrying on the study, according to the roles of the scientific committee in the Kirkuk Health Directorate, was taken according to the administrative issue 4731 on 13 February 2019. For each woman, a commitment was taken informal questionnaire involve, the signature of the patient to participate in the study and all required information such as name, age, occupation, blood group, and others.

Sample collections and serum separation:

5 ml of venous blood was drawn from each woman in both groups using sterile technique. The first tube contains 0.4 ml of sodium citrate for erythro-sedimentation rate (ESR). The second tube contains Ethylene diamine tetra-acetic acid (EDTA) used for complete blood count (CBC) by adding about one ml of the blood. The rest blood sample was discharged gently into the third tube, which contains jell-activator that facilitates blood clotting and obtaining clear sera [23]. Tube 1 and two were inverted several times to a sure no clots and used at once to avoid hemolysis, in case of delay predicting the specimens kept in the refrigerator for no longer than 24 hours. The third tube, after 10 minutes, centrifuged for 5 minutes using the speed 3000 RPM. Then bright, non-hemolysis, no lipemia nor jaundice serum was transferred into another sterile plan tube and kept at −20˚C till to use [24].

Laboratory tests: Involve detection of T. gondii IgM and IgG Abs using ELISA kits and sandwich technique, Vitamin D3 uses a combination of ELISA-fluorescent technique in Mini-Vidas machine, Calcium, inorganic phosphate using a spectrophotometric method and parathyroid hormone using the sandwich ELISA kit. All the tests have been determined according to the leaflet of each kit.

Detection of anti-Toxoplasma gondii using an ELISA IgM kit.

This ELISA kit was brought by Biozek Company the Netherlands from Bio-Activia Company in German and send to our destination.

Principle of ELISA kit for T. gondii:

Immuno-globulins and subsequent identification of the Toxoplasma IgM assay based on capturing the ELISA technique. Which are specifically made to bind an antigen conjugated to peroxidase. The capture technique is performed by adhesion of solid-phase antigen on micro-plate to monoclonal antibodies. The antigen is a purified protein inactivated Toxoplasma gondii antigen.

Detection of anti-Toxoplasma gondii using an ELISA IgG kit. This ELISA kit was brought by Biozek Company–the Netherlands from Bio-Activia Company in German and send to our destination. The content of the kit was the same for IgM except, solid face antigen in the ELISA strips, HRP-conjugate. The test processing and results were the same as those used for IgM. These procedures were performed according to the manufactured company and according to that done by [25].

Vitamin D determination:

The VIDAS® 25-OH Vitamin D total assay design based on a 2-step competitive immune-assay. The kit purchased from biomerurix company-France. The Mini-Vidas machine is an automated machine that determines different laboratory tests, particularly hormonal, immunological tests using a mixed method of ELISA and fluorescent. The purpose of the kit employee was to evaluate the technical and clinical performance of the VIDAS® 25-OH Vitamin D total assay and to compare the result with liquid chromatography Mass Spectrometry/ Mass Spectrometry (LC-MS/MS) AND a commercially available vitamin D immune-assay. Briefly, the procedure included two following main steps: First step: Serum or plasma 25(OH)D dissociated from its protein carrier (DBP) then added to alkaline phosphatase (ALP) conjugated vitamin D-Specific antibody Second step: Unbound ALP antibody exposed to vitamin D analog coated solid-phase receptor. Solid-phase washed, and substrate reagent is added to initiate the fluorescent reaction. An inverse relationship exists between the amount of 25 (OH) D in the sample and the number of relative fluorescence units detected in the serum. The result of each serum obtained after 45 minutes, which involves deficiency below 20 ng/ml, insufficient from 20 to 30 ng/ml, sufficient from 30 to 70 ng/ml and above 70 ng/100ml consider as vitamin D toxicity.

Parathyroid hormone assessment: The specific kit is an ELISA-Biotech Spain

Principle: The Intact PTH immune-assay is an adapted two-site sandwich ELISA. In the assay, standards and patient samples simultaneously incubated with the enzyme-labeled detection antibody and biotin coupled capture antibody in a streptavid in-coated micro-plate well. At the end of the assay incubation, the micro-well is washed to remove unbound components and the enzyme bound to the solid phase, incubated with the substrate tetra-methyl-benzidine (TMB). An acidic stopping solution is then added to stop the reaction and converts the color to yellow. The intensity of the yellow color is directly proportional to the concentration of intact PTH in the sample. Standards are used to generate a dose-response curve of absorbance unit vs. concentration. Concentrations of intact PTH present in the controls and patient samples are determined directly from the standard calibration curve. The typical range is from 10 to 90 pg/ml.

Serum inorganic phosphate determination.

The U.V. spectrophotometry Bi-Labo-France kit was used for the determination of serum inorganic phosphate.

Serum calcium assessment: was done according to the instruction of Randox kit-UK, the manufactured company.

Statistical analysis: All obtained data were unified and arranged in specific tables using Microsoft excel file. Differences in the parameters in both study and control groups were checked by using the manual statistical equation like chi-square and t-student test for exerting variances and significances at the levels of P < 0.05 and P < 0.01.

3. Results

The overall rate of positive toxoplasmosis was 78.43% distributed into the following rates: 22.87%, 49.01%, and 13.07% for IgM, IgG, and IgM + IgG antibodies, p < 0.05. Whereas the examination of sera in control group reveals only 14 sera positive for IgG Abs, the rate was 31.12%. The variance in the rates of IgG Absin both groups was significant, via which the following rates were recorded 49.01% in test groups versus to 31.12% in the control group, Table 1.

Toxoplasma gondii antibodies frequencies concerning women ages shown in Table 2, through which, sera from women in early child age bearing exert high rates of T. gondii IgM than in sera of women aged over than 46 years, P < 0.05. The following IgM rates were recorded 21.21%, 24.59%, and 25% in the first three groups versus to 18.51% in sera of women over 46 years, respectively. Contrary to IgG Abs rate, 59.25% revealed in sera of women aging over 46 years

higher than in sera of younger women. Moreover, the sub-acute case as the sera was positive for both antibodies, IgM and IgG were highly recorded among in age group from 15 to 25 years, the rate was 15.15% compared to 7.40% in two sera of women arguing over than 46 years, P < 0.05. In general the all rate of T. gondii IgM Abs 22.87% versus to 49.01% for IgG Abs in the same table.

From the available data in the questionnaire form, the relationship between the occurrence of toxoplasmosis and women contact with animals, particularly with domesticated cats, chickens, Table 3 was clarifying that, the mean value of T. gondii IgM 0.96 IU/ml in the test group was higher than 0.525 IU/ml in the control group. The same finding was seen regarding IgG Abs, which was positive 1.21 IU/ml in the test group compared to 0.825 IU/ml (negative) in the control group, P < 0.05. Sera from women in early child age bearing exerts high rates of T. gondii IgM than in sera of women aged over 46 years, P < 0.05.

To assess the impact of Toxoplasmosis on women, abortion, Table 4 showed high positivity 63.64% in sera of women who had a single abortion, followed by

42.94% women with multiple abortions whereas women with stillbirth delivery contributed 21.15%, P < 0.05. The rate of women abortions in the current study was 42.30%. T. gondii IgG Abs mean equal to 1.008 IU/ml versus to 0.072 IU/ml for IgM Abs. Furthermore, among women with multiple abortions, the mean IgM Abs level showed 0.83 IU/ml higher rate than in the case of women with single abortion and stillbirth, P < 0.05.

To determine signs and symptoms associated with women’s toxoplasmosis, the more dominant one was a urinary tract infection (UTI), the rate was 43.79%, followed by 29.41%, 20.92%, and 5.88% among women with arthritis, hypertension and diabetes mellitus respectively, P < 0.05. Statistically, the variance in the rates of toxoplasmosis according to the existence of signs and symptoms was not significant, P > 0.05. On the other hand, the mean levels of T. gondii antibodies were 1.29 IU/ml and 1.53 IU/ml for IgM and IgG Abs, respectively. Different high means of both Abs were visible in consider to symptoms; 1.41 IU/ml IgM was highest recorded among women with arthritis, while 2.29 IU/ml mean level was recorded among women with hypertension Table 5.

Some bone markers levels collectively with T. gondii mean Abs was summarized in Table 6, through which; IgG means equal to 1.06 IU/ml(positive) in the test group versus to 0.80 IU/ml in the control group, whereas IgM Abs both were at negative levels, although IgM in the test group was slightly higher at 0.71 IU/ml than 0.505 IU/ml in the control group.

Regarding the four bone biomarkers, all their means were within low levels in the test group compared to normal levels in the control group, P < 0.05 Hypophosphatemia 2.60 mg/100 ml as mean was recorded in sera of women in the test group versus to 3.87 mg/100 mean level in the control group, P < 0.05.

Although the mean value of vitamin D3 13.90 ng/ml in the sera of women in the control group was low compared to 16.59 ng/ml in the test group, in both groups, the condition is a deficiency of vitamin D3. The difference in the values of vitamin D3 in both groups was not significant. Significant differences were seen in the levels of serum parathyroid hormone (PTH) between the test group, which showed hypoparathyroidism, and the mean was 14.96 pg/ml versus to 24.01 pg/ml in sera of women in the control group, P < 0.05.

The frequency of T.gondii Abs, according to vitamin D3 abnormalities, was tabulated in Table 7, via which Toxo-IgM Abs was highly observed 18.43% among sera deficient to vitamin D3 followed by 4.60% and 1.31% for insufficiency and toxicity, P < 0.05. The same finding detected regarding Toxo-IgG Abs, the following rates 31.57%, 9.21%, and 1.97% for a vitamin Ddeficiency, insufficiency, and toxicity were recorded respectively, P,0.05. In general, the total Toxo-Abs was 62.5% distributed in 95 sera, and this rate involves 24.34% for Toxo-IgM Abs versus to 38.15% for Toxo-IgG Abs.

The impact of toxoplasmosis concerning serum vitamin D3 levels denoted as vitamin D3 deficiency. It recorded in sera of 117 women positive for toxoplasmosis; the rate was 76.97% of all total of vitamin D3 abnormality 93.42% compared to 6.58% of women their sera exert an average vitminD3 level. Also, insufficiency recorded at a rate of 14.47%. While toxicity was shown in 3 sera, the rate was 1.97%, P < 0.05.

The relationship between vitamin D3 deficiency, toxoplasmosis, and women’s age was significant; within which women were aging from 15 to 25 years, their sera reveal high rates of deficiency 98.46% compared to other age groups. While vitamin D3 insufficiency highest recorded among women aging from 26 to 35 years, P < 0.05 Table 8.

4. Discussion

The Provinces in the north and west of Iraq suffer from the destruction of infrastructure during 2014 and after with continuous instability. In addition to

uncontrolled construction of houses with inadequate designs, continuous electricity interruption, shortages in the water supply with weak governmental monitoring water. The competition of commercial companies for bringing bad quality drugs had a role in recording several infectious agents with high rates in Iraq particularly, Toxoplasmosis [25], Giardiasis [26], Cyclospora cayetanensis [27], Blastocystis hominis [28].

So, the all rate of seropositive toxoplasmosis 78.43% among women with child, conceiving age was high for these reasons. This rate was due to the sensitivity of the ELISA test compared to the other serological method used by other authors in this regard for the diagnosis of toxoplasmosis in the same province. The overall rate of toxoplasmosis in the present study did not agree with that recorded in the same province by [29] [30] [31], whom they record the following rates: 33.6%, 35.6%, and 31.15%. Also, it has disagreed with those recorded [32] [33] [34], whom they record 92.1%, 48.9% and 38.56% of toxoplasmosis in the same province, respectively. These characteristic findings of T. gondii seropositivity were higher than those recorded by other studies, including Egypt, by [35] [36]. In Turkey by [37]. In Malaysia, India, Saudi Arabia, Mali, and northeast Thailand [25]. Also, it was deficient when it was compared with 83.6% in Ethiopia recorded by [38]. The variability in the rates might be due to several factors, such as the size of samples, type of laboratory method, site of the study, and type of the patient(infected and not infected with other infectious agents) [17].

Regarding women ages and high incidence of Toxo-IgM Abs 0.96 IU /ml equivocal levels (0.9 to 0.99 IU/ml), this finding is vital to woman health. The possibility for seroconversion after a period gives rise in IgM Abs and, subsequently, the adverse effects of toxoplasmosis like abortion and stillbirth. The importance of this finding is with the high occurrence of Toxo-IgM Abs in young aged women within the current study, this group of women is very fertile; the prospect for pregnancy lost is going to be high, notably within the first trimester and a few less within the second trimester. This seroconversion within the third trimester becomes a lot of harmful, as a result of congenital toxoplasmosis exerting when delivery 40. On the other hand, Toxo-IgG Abs 49.01% was high and referring that all the women in the current study got T. gained previously, and they have an anti-Toxoplasma antibody. However, this finding of Toxo-IgG Abs in a high level demands assurance like watching of rising titer to exclude seroconversion and to assure protection. Also, these high rates in the levels of both Toxo-Abs reflect the degree of contamination with the Toxoplasma stages in Kirkuk Province. So, Health education for women of childbearing age should include information about meat-, soil-, and cat feces-related toxoplasmosis prevention. This finding, with agreement with that recorded in Najaf Province-Iraq [39] [40] [41] [42], suggests that T. gondii Abs increases with the increasing of the women age This finding is not compatible with those recorded in Iraq in Tikrit 2008 [43], Kirkuk in 2013 [44] and 2014 [45] and with that record in Nepal 2014 [45].

Stray cats dwelling houses had a significant role in spreading the oocysts of T.gondii, and unprotection during meat handling and washing vegetables can increase the rate of toxoplasmosis, particularly in women [25]. Surprise in recent, the number of indoor cats is not high. But the outcome of infection among women contact with cat, meat and vegetable high in the current study as both IgM and IgG Abs were significant, this high rate explained by some factor such as consumption of different kinds of meat from different origin (Imported meat), this meat mostly brought to Iraq without governmental inspection, wrong store due to continuous electricity interruption, poorly auditing cats by veterinarian director in addition to absence of specific drug used for treatment of toxoplasmosis in Iraq. All of these factors had a role in this relationship. This finding was agreed that recorded in Karbala-Iraq [46] [47].

Vertical transmission of T. gondii parasite in women mostly evokes abortion or lead to congenital abnormalities. Despite the non-significant relation between the number of abortion and Toxo-Abs frequencies, in the current study. However, a high incidence of 63.64% in sera of women with single abortion is vital because their sera reveal 0.72 IU/ml (negative titer) for IgM versus to 1.025 IU/ml for IgG (borderline positive). In this condition, women should aware of getting the second infection, and this is due the chance of increasing, rising titer of IgM (seroconversion) in association to the partially protects as IgG Abs are at the level of partially protection [48]. Stillbirth is a major but often neglected public health issue [48]. The current findings indicated high stillbirth rates in Kirkuk-Iraq and identified the risk categories which were in early aged women, The development and implementation of number of maternal and child health programs at national level to date do not have a significant role in the increase or decrease of inequalities [49]. So, further studies required to evaluate the real causes of stillbirth in comparing to toxoplasmosis.

The co-existence of some signs and symptoms like UTI, arthritis, Hypertension, and DM in the current study should be taken into consideration, because of obtaining both IgM and IgG Abs with high mean compared to sera of women positive for toxoplasmosis only. The higher rate of recording of UTI might be due to contamination with genital flora, a shorter urethra, sexual activities, certain types of birth control, and the use of spermicidal agents [50]. All collectively can enhance the frequency of UTI in women. Regarding sign of arthritis, might be attributed to the effects of vitamin D deficiency in the current study, although in a previous study in the same Province done between 2014 to-2015 [51] attribute arthritis to toxoplasmosis. Moreover, most of the endo-parasitism evoke anemia, so the load on the urinary system becomes apparent, and one suggestion for getting hypertension during toxoplasmosis might be due changes in some hormones like erythropoietin and anti-diuretic hormone (ADH) the former is responsible for anemia and the later definitively in changing urine consistency and osmolality. Additionally the possibility of adrenalin gland, which may interfere the level of cortisol hormone that increases the compliance of D.M [52].

Regarding some bone marker tests during toxoplasmosis, S.inorganic phosphorus is within normal with a significant difference with sera in the control group. Additionally, hypocalcemia, low PTH, and vitaminD3 deficiency, all referring to the picture of hypoparathyroidism. Although the etiology for this might be genetic (chromosomal) or induction by chronic diseases such as thyroid diseases, tonsillitis, but, role of Toxoplasma parasite invading cervical area lymph nodes(lymphadenopathy) had a role in interfering the function of PTH.

Furthermore, vitamin deficiency in Iraq nowadays is a mystery because the incidence of vitamin D in Iraqi communities is high. Causes to that might be less exposure to sunlight that permits good penetration for the manufacturing of sufficient amount of vitamin D; changes in the climate also have a role in this deficiency. However, the effect of T. gondii on the bone itself remains obscure because the bone is a rigid tissue and the morphology of osteocytes is not proper for the development of the parasite inside it. Moreover osteomalacia can result in invading the parasite to the kidneys, tubules, and small intestinal tissue through which the rate of calcium reabsorption becomes low and bone trials for compensating calcium shortage leads to osteoporosis or bone fragility mostly increases fracture occurrence and other signs and symptoms of arthritis.

High level of Toxo-IgM 18.43% association with vitamin deficiency refers to the chance of women gutting adverse effects of toxoplasmosis will be high. Additionally, vitamin D deficiency might be due to a poor diet with some minerals particularly S. magnesium. So, womens supplements with oral vitamin D, Ca2+, minerals may have a substantial role in preventing vitamin D shortage. This plane should be accompanied by finding the most effective treatment for toxoplasmosis in women rather than the use of spiramycin, which mostly used in Iraqi clinics.

5. Conclusions

The prevalence of T. gondii Abs in the sera of women was high, particularly in young aged women. Acute toxoplasmosis (High level of IgM) accompanied by vitamin D deficiency is higher among women aging from 15 to 25 years, which may have a role in women’s abortion and congenital abnormalities. Seroconversion from latency is still present because the mean level of IgG Abs was within the borderline.

The relationship between toxoplasmosis and vitamin D deficiency is significant, and this finding is preliminary and prone to women for getting osteoporosis.
