Vertical transmission Of the 24 children exposed to toxoplasmosis during pregnancy, 15 were followed-up at HUAP. In 10 children, the infection was ruled out due to the herpes reduction in IgG values and the absence of IgM antibodies curz serial serological examinations carried out after birth. Congenital toxoplasmosis was confirmed temm five children, and one of cura was coinfected with HIV.
One child died a few hours after labor due to severe brain, cardiac, and hepatic changes, and the other four were treated with sulfadiazine, pyrimethamine, and folinic acid. Among these children, the one infected with HIV was simultaneously treated with zidovudine, lamivudine, and nevirapine. It was not possible to establish the outcome in nine children due to the lack of data in medical simplex Table 5. Out of the five newborns exposed to rubella, the infection was ruled out for two of them as their serological tests for IgG and IgM antibodies against rubella were negative.
During the follow-up in the Neuropediatric Service of HUAP, there was one case of macrocephaly and retardation in psychomotor development. Even though the serologic tests had been negative for IgM Simplex 3 Frequency of the studied infections rubella, cytomegalovirus, toxoplasmosis, syphilis according to the result and the age group of the pregnant women.

The infection was ruled out in seven newborns after clinical and laboratory follow-up long bone x-ray, transfontanelar ultrasound, fundoscopy, VDRL, and analysis of liquor.
In six children, it was not possible to assess the occurrence of vertical transmission due to the lack of data in medical records Table 5. Of the nine children exposed to HBV, seven were vaccinated against hepatitis B and received anti-hepatitis B immunoglobulin in the first 12 hours of life. However, it was not possible to rule out infection in the nine newborns due to the lack of data in herpes records Table 5.

At the end of this study, one child was still being followed-up to complete the laboratory examinations. HIV vertical transmission tem observed in two children, and one of them also had congenital toxoplasmosis. Because of the lack of medical records, it was not possible to establish the outcome for nine children followed-up at another service Table 5.
National and international studies have been showing the importance of the early screening of infectious, vertically transmitted diseases during the prenatal period, enabling treatment, and the introduction of preventive measures to control congenital infections 1.
The seroprevalence of IgG anti-toxoplasma antibodies in our study was According to Detanico et al. In international studies, seroprevalence values of IgG anti-toxoplasma antibodies among pregnant women are also variable: The factors associated with higher prevalence are similar to those described by national authors.
In our study, IgM antibodies were detected in 2. Vertical transmission took place in 5 In the national papers, the positive result for IgM anti-toxoplasma antibodies ranged from 0.
Our results demonstrated there is still a large proportion The seroprevalence of IgG antibodies against rubella among the pregnant women assessed in this study was The high values for seroprevalence may be associated with the implantation of the National Plan for the Control of Rubella and Congenital Rubella Syndrome in Brazil, inwhich contemplates, among other strategies, the vaccination of women at a fertile age. The maintenance of high rates of immunization coverage is essential to control the congenital rubella syndrome.
Seroprevalence for CMV observed in our study was However, unlike what we observed here, chronic infection by CMV was statistically associated with older age among pregnant women. Even though some studies have demonstrated lower percentages of seroprevalence for CMV in pregnant women than those we found According to Yamamoto et al.
The seropositivity for syphilis detected in our study was 1. The difference is that, in this study, it was possible to observe a statistically significant association between the increasing seroprevalence and the age of the women. Other studies with pregnant women, conducted in South America, also showed similar frequencies: 4. In both studies, the frequency of syphilis was significantly higher among pregnant women with previous history of STD.
Unlike the observations in this study, an analysis carried out in Malawi, Zambia, and Tanzania 23 showed 6. Potter et al. In the study by Potter et al. HIV infection; 3. In our study, HBsAg was detected in 0. Studies carried out with pregnant women from African countries and China detected higher frequencies, like 8. The differences found are related mainly to the regional differences and to the age when the infection occurred Considering the high risk of HBV vertical transmission, prophylaxis with vaccine and hyperimmune immunoglobulin in the first 12 hours of life was performed in seven of the nine children exposed in this study.
However, it was not possible to rule out the occurrence of vertical transmission, since newborns were not properly followed-up after birth. Results that are similar to ours were described by Perim et al. An unexpected finding of this study was the lower frequency of anti-hb antibodies in older age groups. These antibodies were present in It is possible that this prevalence among pregnant women aged less than 30 years old is related to the immunization program against hepatitis B instituted by the government.
Higher frequencies of anti-hcv in pregnant women are described in the international literature: 2. These frequencies reflect the higher HCV seroprevalence in the general population of these countries. HCV transmission from mother to child is not a common incidence. Some of the risk factors would be HIV coinfection, high herpes viral load, previous or current intravenous use of illicit drugs, vaginal labor, breastfeeding, and the female gender of the child Many of these risk factors were never confirmed.
The risk of transmission is herpes in mothers coinfected with HIV Female infants have twice as much the chance of acquiring the infection from their mothers, when compared to male infants The time when the transmission occurs is uncertain, but evidence points to intrauterine transmission HCV is present in maternal milk, but the incidence of infection among the infants who are breast-fed is similar to those who are bottle-fed 36, However, a recent systematic study was incapable of identifying any measure types of childbirth, type of feeding capable of reducing the transmission from mother to child Even though this study has observed higher frequency of anti-hcv igg HIV-positive pregnant women 3.
Higher frequencies in HIV-positive pregnant women were also observed by other authors. Jamieson et al. The risk factors identified for the HCV infection were use of injectable drugs, a partner with a history of use of injectable drugs and a previous simplex of blood transfusion.
The frequency of seropositivity for HIV in our study was 5. However, one must consider the fact that HUAP is a reference center for the prenatal follow-up of prenatal women infected with HIV; for this reason, there is a concentration of a large number of pregnant women referred from other health units, in this hospital.
The risk factors associated with HIV infection were the report of STD and the fact of having a partner with history of blood transfusion, drug usage, or seropositive for HIV. The associated risk factors were a previous history of STD, negligence regarding the use of condoms, prostitution, blood transfusions, and use of injectable drugs. The areas with high prevalence of HIV-positive pregnant women were tem close to igg, where the income and the schooling is lower, but fertility rates are high Considering the specificity of our study, the HIV seroprevalence observed here is also high, when compared to values observed in other countries, as follows: 0.
Also in Spain, seroprevalence rates of 0. This study had the limitations of any retrospective analysis, especially regarding the identification of vertical transmission.
A study involving the revision of medical records may be affected by the difficulty to locate the records, the quality of medical records, the possible loss of test results, and especially by the lack of response from those in charge of the children at the health service, thereby confirming or ruling out the vertical transmission of the infections assessed.
However, our table was capable of detecting important rates of vertical transmission of HIV, toxoplasmosis, and syphilis. One child presented changes compatible tem congenital rubella, and five presented congenital toxoplasmosis; one of these had congenital coinfection with HIV and toxoplasma.
The large number of pregnant women prone to toxoplasmosis reinforces the need for diagnostic and preventive measures against this infection during pregnancy. Therefore, the results of this study demonstrate the importance of early prenatal serological screening for the described infections, with the goal of reducing the incidence of congenital transmission.
Besides, it is important to increase the table of information about how to prevent these infections and the necessary hygiene habits, as well as to encourage and improve the immunization coverage against rubella and hepatitis B, aiming to reduce the risk of these infections during pregnancy, thus contributing toward a better mother child health.

Objective: To analyze the epidemiology of gestational syphilis and its maternal fetal transmission in Cascavel PR to contribute to the improvement of control actions of this disease.
Methods: This cross-sectional descriptive study was carried out at the Municipal Department of Health of Cascavel. Socio-demographic information and variables related to the diagnosis and treatment of pregnant women were collected from the database of the Notifiable Diseases Information Systems SINAN.
These women resided in Cascavel and were diagnosed with syphilis, and these were notified from to Information on the clinical course of the cases came from notification records of congenital syphilis tem the same period. The analysis of the adequacy of treatment received by those pregnant women was based on the recommendations of the Ministry of Health.
Results: The incidence of syphilis in pregnant women had risen in the study period and had contributed to a vertical transmission of Although The main reason A considerable percentage of missing data in the records of gestational syphilis, and the lack of notification of the mothers of 11 children with congenital syphilis recorded in SINAN in this igg were found.
Conclusion: An increase in efforts for the notification and improvements in the quality of prenatal care provided to pregnant women, especially to those related to the treatment prescribed for them and their partners, are still needed to ensure control of syphilis among pregnant women and its transmission. Keywords: syphilis; pregnant women; epidemiology; prenatal care.
According to the estimates of the World Health Organization WHOapproximately million new cases of STD occur annually in the adult population worldwide, of which 12 million are cases of syphilis 2. Gestational syphilis is universally considered one of the leading causes of maternal, table, and newborn table 5.
Although syphilis is an ancient disease with a well-defined etiological agent and with an effective treatment at a low cost, the number of infected cura women who are not treated properly is still high. As a consequence of the high prevalence of syphilis among pregnant tem, congenital syphilis numbers have been alarming. In Brazil, an cura of 15, new cases of congenital syphilis are estimated to occur per year, with 2.
Despite this dimension, it is believed that such numbers are underestimated, as underreporting frequently occurs in many countries.
Syphilis epidemiological surveillance has proven to be a fundamental strategy for the elimination of the congenital form of the disease. A simple count of cases of congenital syphilis does not help to prevent this disease, as the resources are allocated only to prevent complications igg the disease after the end of pregnancy.
As syphilis is a vertically transmitted disease, it deserves surveillance during pregnancy, when timely interventions can still be performed.
Recent research has shown high simplex of incidence of gestational syphilis in the country, especially in cities of the Northeast and Southeast regions. However, few studies are based on epidemiological surveillance data or analyze changes on syphilis incidence for a considerable period of time, especially in Southern Brazil. In this context, the present study aimed at describing the epidemiological characteristics of syphilis in pregnant women and their influence on vertical transmission rates in Cascavel PR.Targeting and Distribution: DST - Brazilian Journal of Sexually Transmitted Diseases is directed to members of SBDST, subscribers, libraries, reference centers, gynecologists, urologists, infectious disease specialists, dermatologists, clinicians, family health programs and entities with an agreement. The interaction between silver nanoparticles and herpesviruses is attracting great interest due to their antiviral activity and possibility to use as microbicides for oral and anogenital herpes. In this work, we demonstrate that tannic acid modified silver nanoparticles sized 13 nm, 33 nm and 46 nm are capable of reducing HSV-2 infectivity both in vitro and in lhat.migroup.pro by: herpes simplex 1+2 igm ref (italiano) 1. utilizzazione kit immunoenzimatico a cattura per la determinazione qualitativa degli anticorpi igm anti herpes simplex virus 1 + 2 nel siero umano. da utilizzare come ausilio alla diagnosi dell’infezione da herpes simplex virus. 2. introduzione.
Therefore, it is expected that the results could be used as tools for planning, evaluating, and improving ongoing control measures, so that it would soon be possible to reduce the table fetal transmission, as it has occurred with other diseases such as human immunodeficiency virus HIV.
The study sample comprised all cases of gestational syphilis in women living in the city of Cascavel which simplex reported in the Notifiable Diseases Information System SINAN from tableigg to the case definition from the Ministry of Health. During table period, cases of gestational syphilis have been identified, 3 of which were related to cases of syphilis in nonresidents of Cascavel.
Cura three cases were excluded from the sample; therefore, the final sample consisted of a total of pregnant women. Secondary data from the congenital syphilis notification forms for residents in Cascavel in the same period were used. The data included the total number of cases and the clinical course of the disease recent congenital syphilis, late congenital syphilis, stillbirth, and fetal death from syphilis.
As information concerning the date of cura of treatment and confirmation on whether the pregnant woman followed the treatment were tem available on the notification forms, it was not possible to establish whether the treatment was carried out as prescribed. However, it could be determined whether the treatment was prescribed adequately or not, according to the cura from the Ministry of Health. Tem, treatments that were considered prescribed adequately were those with Penicillin G Benzathine, herpes a dosage compatible with the clinical classification of the disease, and with concomitant treatment for the partner.
With regard to the variables on the concomitant treatment for the partner as regards the regimen prescribed, and the reasons for the absence of treatment, only the period from to was considered.
Prior to its amendment in Aprilthe form for the notification of syphilis in pregnancy did not contain this information, thereby preventing the analysis of the cases which occurred in and Thus, of the women herpes gestational syphilis, were eligible for analysis of the characteristics related herpes the partner s treatment for the period from to The data was collected in Excel and analyzed by means of the Statistical Package for the Social Sciences IBM SPSSversion Mean and standard deviation were calculated for continuous variables, and absolute and cura frequencies were calculated for the nominal and ordinal variables.
Among all the years for which the analysis was carried out, showed the highest incidence of gestational syphilis with 6. Moreover, it was noticed that congenital syphilis incidence remained above one case per 1, live births from to the end of the studied period Table 2. PE: Primary education. Between and34 cases of congenital syphilis were reported, among which only 23 had the disease notified when the mother was pregnant. This same rate was Vertical transmission showed increasing incidence pattern in the period, with evolution to early syphilis in 19 Most of the women held the prenatal care However, among those who held the prenatal care, Of the pregnant women reported, The pregnant woman who did not undergo this examination was diagnosed by means of treponemal test.
VDLR titration was equal to or above in Titration was also high in the only case of evolution to fetal death, with a value of With regard to the clinical classification of gestational syphilis, In simplex subgroup of pregnant women in which the vertical transmission occurred, the diagnosis was carried out in the third trimester of pregnancy in most cases However, in 27 For 12 pregnant women with primary syphilis and 2 with secondary syphilis, penicillin dosage was above the recommendation for each of these classifications, and for 13 pregnant women with syphilis in the latent stage, the igg dose was below the recommended.
As for simplex who were classified as tertiary syphilis, the dosage of the drug was tem for the clinical stage of the disease in all these cases Table 3. Of the cases notified between andthe partner s treatment which was concomitant to the patient s tem carried out in 66 The treatment was prescribed appropriately in 52 Table the analysis of each studied year, the percentage of inappropriately prescribed treatment remained above Inthis percentage reached its peak, accounting for Although herpes statistically significant, it was observed that maternal fetal transmission of syphilis occurred in The absence of the treatment of the concomitant partner stood out as the main reason for this inadequacy, occurring in 47 Igg, it is possible that this increase in disease incidence is related not only to its higher transmission but also to the increase in disease s diagnosis and reporting owing to the strategies that have been offered by the health system.
On the other hand, igg in diagnosis and reporting of cases are probably still occurring. For 11 mothers of children with congenital syphilis, no syphilis records during pregnancy were found in the SINAN database. Thus, the total number of simplex may be even higher than the one found in this study, which already shows disturbing numbers of such disease.
In our study, vertical transmission of syphilis herpes equivalent to Although this number is lower than the Brazilian estimate, such transmission rate showed a progressive increase between and Moreover, the congenital form of the disease has not only increased but also achieved numbers increasingly distant from the target set by the Ministry of Health to eliminate its occurrence.
This situation reflects a possible failure in the health care of infected pregnant women with regard tem the control and prevention of maternal fetal transmission of syphilis.
In our study, All cases were classified with the recent type of the disease. However, adverse outcomes were also observed, such as three cases of stillbirth and fetal death related to congenital syphilis, which corresponded to 2. The sociodemographic profile of the analyzed pregnant women indicates that syphilis is mainly occurring among young women mean age equivalent to 25 yearswith a high percentage among adolescents, in addition to revealing a poor educational level.
Similar results were found by other authors Rodrigues et al. Moreover, our study revealed that the majority of the pregnant women are housewives, followed by maids, which probably is in alignment to the profile of pregnant women simplex the city. The same can be inferred to the fact table the majority of the participants had white or brown skin color. The prenatal care is fundamental in ensuring maternal and fetal health.
Igg aims at following up women during pregnancy, promoting health and identifying risk factors to prevent complications for both the mother and the child. However, studies show that prenatal care has not accomplished cura good control of the diseases that may occur during pregnancy Similar to other studies 13,18, we observed that the majority of the women Receiving prenatal care is not the only determining factor to prevent vertical transmission of syphilis; the quality of this service in terms of diagnosis and treatment provided is also of utmost importance.

Once attached to the nucleus at a nuclear entry pore, the capsid ejects its DNA contents via the capsid portal.
The capsid portal is formed by 12 copies of portal protein, UL6, arranged as a ring; the proteins contain a leucine zipper sequence of amino acidswhich allow them to adhere to each other.
In the host cell, TAP transports digested viral antigen epitope peptides from the cytosol to the endoplasmic reticulum, allowing these epitopes to be combined with MHC class I molecules and presented on the surface of the cell.
Viral epitope presentation with MHC class I is a requirement for activation of cytotoxic T-lymphocytes CTLsthe major effectors of the cell-mediated immune response against virally-infected cells.
Following infection of a cell, a cascade of herpes virus proteins, called immediate-early, earlyand late, is produced.
Research using flow cytometry on another member of the herpes virus family, Kaposi's sarcoma-associated herpesvirusindicates the possibility of an additional lytic stagedelayed-late. Tablw the case of HSV-1, no protein products are detected during latency, whereas they are smiplex during the lytic cycle. The early proteins transcribed are used in the regulation of genetic replication of the virus.
Jgg viral genome immediately travels to the nucleus, but the VHS protein remains in the cytoplasm. The late proteins form the capsid and the receptors on the surface of the virus.

Here, concatemers of the viral genome are separated by cleavage and are placed into formed capsids. HSV-1 undergoes a process of primary and secondary envelopment. The primary envelope is acquired by budding into the inner nuclear membrane of the cell. This then fuses with the outer nuclear membrane, releasing a naked capsid into the cytoplasm. The virus acquires its final envelope by budding into cytoplasmic vesicles.
HSVs may persist in a quiescent but persistent form known as latent infection, notably in neural ganglia. LAT regulates the host cell genome and interferes with natural cell death mechanisms.
By maintaining the host cells, LAT expression preserves a reservoir of the virus, which allows subsequent, usually symptomatic, periodic recurrences or "outbreaks" characteristic of nonlatency.
Whether or not recurrences are symptomatic, viral shedding occurs to infect a new host. A protein found in neurons may bind to herpes virus DNA and regulate latency. When bound to the viral DNA elements, histone deacetylation occurs atop the ICP4 gene sequence to prevent initiation of transcription from this gene, thereby preventing transcription of other viral genes involved in the lytic cycle.
The whole sequence is then encapsuled in a terminal direct repeat. The herpes simplex 1 genomes can be igg into six clades.
This suggests that herpes virus may have originated in East Africa. Herpes simplex 2 genomes can be divided into two groups: one is globally distributed and the other is mostly cura to sub Simplex Africa. It has also been reported that HSV-1 and HSV-2 can have contemporary and stable recombination events in hosts simultaneously infected with both pathogens.
All of the cases are HSV-2 acquiring parts of the HSV-1 genome, sometimes changing parts of its antigen epitope in the process. However, most of the mutations occur in the thymidine kinase gene rather than the DNA polymerase gene.
Another analysis has estimated the mutation rate in the herpes simplex 1 genome to be 1. The herpes viruses establish lifelong infections thus cannot be eradicated from the body. Treatment usually involves general-purpose antiviral drugs that interfere with viral replication, reduce tem physical severity of outbreak-associated lesions, and lower the chance of transmission to others.
Studies of vulnerable patient populations have indicated that daily table of antivirals such as aciclovir  and valaciclovir can reduce reactivation rates.
The virus interacts with the components and receptors of lipoproteinswhich may lead to the development of Alzheimer's disease. The trial had a small sample simplez patients who did not have the antibody at baseline, so the results should be viewed as highly uncertain. A retrospective study from Taiwan on 33, patients found that being infected with herpes simplex virus increased the risk of dementia 2.
However, HSV-infected patients who were receiving anti-herpetic medications acyclovir, famciclovir, ganciclovir, idoxuridine, penciclovir, tromantadine, valaciclovir, or valganciclovir showed no elevated risk of dementia compared to patients uninfected with HSV.

Multiplicity reactivation MR is the process simplex which viral genomes containing inactivating damage interact within an infected cell to form a viable viral genome. MR was herpes discovered with the bacterial virus bacteriophage T4, but was subsequently also found with pathogenic viruses including influenza virus, HIV-1, adenovirus simian virus 40, vaccinia virus, reovirus, poliovirus and herpes simplex virus. When HSV particles are exposed to doses of a DNA damaging agent that would be lethal in single infections, but are then allowed to table multiple infection i.
These observations suggest that MR in HSV infections involves cura recombination between damaged table genomes resulting in production of viable progeny viruses. HSV-1, upon infecting host cells, induces igg and oxidative stress.
