RESUMO

BACKGROUND: In patients with severe neutropenia, infections can rapidly become serious and life-threatening. It is essential to understand whether pregnancy induces changes in neutrophil levels thereby posing an increased threat to the health of gravidae. METHODOLOGY: This cross-sectional study was conducted in San Health District (Mali) and involved pregnant women infected or not by malaria parasites and non-pregnant healthy volunteers. Subjects were categorized as having neutropenia, normal neutrophil levels, and neutrophilia regarding their neutrophil levels. A logistic regression analysis was performed to determine factors associated with neutrophil level variation in pregnant women. RESULTS: Whether or not the pregnant women were infected with malaria, 98 of the 202 cases (48.5%) showed neutrophilia. Surprisingly, 67 of the 71 cases of neutropenia (94.4%) observed in this study concerned healthy people who were not pregnant. The mean percentage of neutrophil levels was significantly (p < 0.001) lower (49.9%) in the first trimester compared to the second trimester of pregnancy (62.0%). A logistic regression model showed that compared to early pregnancy, the second (OR = 12.9, 95% CI 2.2-248.1, p = 0.018) and the third trimesters (OR = 13.7, 95% CI 2.3-257.5, p = 0.016) were strongly associated with the increase of neutrophil levels. CONCLUSIONS: Pregnancy can induce the production of mature neutrophils that are continually released into circulation. Neutrophil levels were lower during the first trimester of the pregnancy compared to the second and third trimesters, but not affected by the presence or absence of malaria infection.

RESUMO

OBJECTIVE: To evaluate the cost effectiveness of universal screening for hepatitis B immunity and vaccination among pregnant women in the United States. METHODS: We designed a decision-analytic model to evaluate the outcomes, costs, and cost effectiveness associated with universal hepatitis B virus (HBV) immunity screening in pregnancy with vaccination of susceptible individuals compared with no screening. A theoretical cohort of 3.6 million women, the approximate number of annual live births in the United States, was used. Outcomes included cases of HBV, hepatocellular carcinoma, decompensated cirrhosis, liver transplant and death, in addition to cost and quality-adjusted life-years (QALYs). Model inputs were derived from the literature, and the willingness-to-pay threshold was $50,000 per QALY. Univariate sensitivity analyses and Monte Carlo simulation models were performed to evaluate the robustness of the results. RESULTS: In a theoretical cohort of 3.6 million women, universal HBV immunity screening and vaccination resulted in 1,702 fewer cases of HBV, seven fewer cases of decompensated cirrhosis, four fewer liver transplants, and 11 fewer deaths over the life expectancy of a woman after pregnancy. Universal screening and vaccination were found to be cost effective, with an incremental cost-effectiveness ratio of $1,890 per QALY. Sensitivity analyses demonstrated the model was robust even when the prevalence of HBV immunity was high and the annual risk of HBV acquisition low. CONCLUSION: Among pregnant women in the United States, universal HBV immunity screening and vaccination of susceptible persons is cost effective compared with not routinely screening and vaccinating.

RESUMO

OBJECTIVE: To investigate whether risk factor-based screening in pregnancy is failing to identify women with hepatitis C virus (HCV) infection and to assess the cost-effectiveness of universal screening. DESIGN: Retrospective study and model-based economic evaluation. SETTING: Two urban tertiary referral maternity units, currently using risk factor-based screening for HCV infection. POPULATION: Pregnant women who had been tested for hepatitis B, HIV but not HCV. METHODS: Anonymised sera were tested for HCV antibody. Positive sera were tested for HCV antigen. A cost-effectiveness analysis of a change to universal screening was performed using a Markov model to simulate disease progression and Monte Carlo simulations for probabilistic sensitivity analysis. MAIN OUTCOME MEASURES: Presence of HCV antigen and cost per quality-adjusted life year (QALY). RESULTS: In all, 4655 samples were analysed. Twenty had HCV antibodies and five HCV antigen. This gives an active infection rate of 5/4655, or 0.11%, compared with a rate of 0.15% in the risk-factor group. This prevalence is 65% lower than a previous study in the same hospitals from 2001 to 2005. The calculated incremental cost-effectiveness ratio (ICER) for universal screening was €3,315 per QALY gained. CONCLUSION: This study showed that the prevalence of HCV infection in pregnant women in the Dublin region has declined by 65% over the past two decades. Risk factor-based screening misses a significant proportion of infections. A change to universal maternal screening for hepatitis C would be cost-effective in our population. TWEETABLE ABSTRACT: Universal maternal screening for hepatitis C is cost-effective in this urban Irish population.

RESUMO

OBJECTIVE: To assess the cost-effectiveness of prenatal detection of congenital cytomegalovirus (cCMV) following maternal primary infection in the first trimester within standard pregnancy follow-up or involving population-based screening (serological testing at 7 and 12 weeks of gestation), with or without secondary prevention (valaciclovir) in maternal CMV primary infection. DESIGN: Cost-effectiveness study from the perspective of the French national health insurance system. SETTING: Cost-effectiveness based on previously published probability estimates and associated plausible ranges hypothetical population of 1,000,000 pregnant women. POPULATION: Hypothetical population of 1,000,000 pregnant women. METHODS: Cost-effectiveness of detecting fetal cCMV in terms of the total direct medical costs involved and associated expected outcomes. MAIN OUTCOME MEASURES: Detection rates and clinical outcomes at birth. RESULTS: Moving to a population-based approach for targeting fetal CMV infections would generate high monetary and organizational costs while increasing detection rates from 15% to 94%. This resource allocation would help implementing horizontal equity according to which individuals with similar medical needs should be treated equally. Secondary prevention with valaciclovir had a significant effect on maternal-fetal CMV transmission and clinical outcomes in newborns, with a 58% decrease of severely infected newborns for a 3.5% additional total costs. Accounting for women decision-making (amniocentesis uptake and termination of pregnancy in severe cases) did not impact the cost-effectiveness results. CONCLUSIONS: These findings could fuel thinking on the opportunity of developing clinical guidelines to rule identification of cCMV infection and administration of in-utero treatment. These findings could fuel the development of clinical guidelines on the identification of congenital CMV infection and the administration of treatment in utero. TWEETABLE ABSTRACT: CMV serological screening followed by valaciclovir prevention may prevent 58% to 71% of severe cCMV cases for 38 € per pregnancy.

RESUMO

Importance: Biological data are lacking with respect to risk of vertical transmission and mechanisms of fetoplacental protection in maternal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Objective: To quantify SARS-CoV-2 viral load in maternal and neonatal biofluids, transplacental passage of anti-SARS-CoV-2 antibody, and incidence of fetoplacental infection. Design, Setting, and Participants: This cohort study was conducted among pregnant women presenting for care at 3 tertiary care centers in Boston, Massachusetts. Women with reverse transcription-polymerase chain reaction (RT-PCR) results positive for SARS-CoV-2 were recruited from April 2 to June 13, 2020, and follow-up occurred through July 10, 2020. Contemporaneous participants without SARS-CoV-2 infection were enrolled as a convenience sample from pregnant women with RT-PCR results negative for SARS-CoV-2. Exposures: SARS-CoV-2 infection in pregnancy, defined by nasopharyngeal swab RT-PCR. Main Outcomes and Measures: The main outcomes were SARS-CoV-2 viral load in maternal plasma or respiratory fluids and umbilical cord plasma, quantification of anti-SARS-CoV-2 antibodies in maternal and cord plasma, and presence of SARS-CoV-2 RNA in the placenta. Results: Among 127 pregnant women enrolled, 64 with RT-PCR results positive for SARS-CoV-2 (mean [SD] age, 31.6 [5.6] years) and 63 with RT-PCR results negative for SARS-CoV-2 (mean [SD] age, 33.9 [5.4] years) provided samples for analysis. Of women with SARS-CoV-2 infection, 23 (36%) were asymptomatic, 22 (34%) had mild disease, 7 (11%) had moderate disease, 10 (16%) had severe disease, and 2 (3%) had critical disease. In viral load analyses among 107 women, there was no detectable viremia in maternal or cord blood and no evidence of vertical transmission. Among 77 neonates tested in whom SARS-CoV-2 antibodies were quantified in cord blood, 1 had detectable immunoglobuilin M to nucleocapsid. Among 88 placentas tested, SARS-CoV-2 RNA was not detected in any. In antibody analyses among 37 women with SARS-CoV-2 infection, anti-receptor binding domain immunoglobin G was detected in 24 women (65%) and anti-nucleocapsid was detected in 26 women (70%). Mother-to-neonate transfer of anti-SARS-CoV-2 antibodies was significantly lower than transfer of anti-influenza hemagglutinin A antibodies (mean [SD] cord-to-maternal ratio: anti-receptor binding domain immunoglobin G, 0.72 [0.57]; anti-nucleocapsid, 0.74 [0.44]; anti-influenza, 1.44 [0.80]; P < .001). Nonoverlapping placental expression of SARS-CoV-2 receptors angiotensin-converting enzyme 2 and transmembrane serine protease 2 was noted. Conclusions and Relevance: In this cohort study, there was no evidence of placental infection or definitive vertical transmission of SARS-CoV-2. Transplacental transfer of anti-SARS-CoV-2 antibodies was inefficient. Lack of viremia and reduced coexpression and colocalization of placental angiotensin-converting enzyme 2 and transmembrane serine protease 2 may serve as protective mechanisms against vertical transmission.

RESUMO

Limited data are available for pregnant women affected by SARS-CoV-2. Serological tests are critically important for determining SARS-CoV-2 exposures within both individuals and populations. We validated a SARS-CoV-2 spike receptor binding domain serological test using 834 pre-pandemic samples and 31 samples from COVID-19 recovered donors. We then completed SARS-CoV-2 serological testing of 1,293 parturient women at two centers in Philadelphia from April 4 to June 3, 2020. We found 80/1,293 (6.2%) of parturient women possessed IgG and/or IgM SARS-CoV-2-specific antibodies. We found race/ethnicity differences in seroprevalence rates, with higher rates in Black/non-Hispanic and Hispanic/Latino women. Of the 72 seropositive women who also received nasopharyngeal polymerase chain reaction testing during pregnancy, 46 (64%) were positive. Continued serologic surveillance among pregnant women may inform perinatal clinical practices and can potentially be used to estimate exposure to SARS-CoV-2 within the community.

RESUMO

RATIONALE: Tenofovir (TFV) is a first-line antiviral agent against hepatitis B virus (HBV) and is recommended for the prevention of mother-to-infant transmission of HBV. To study the distribution of TFV in umbilical cord plasma and amniotic fluid of HBV-infected pregnant women, a rapid and sensitive method for TFV determination was developed and validated. METHODS: The quantification method was developed using liquid chromatography coupled to tandem mass spectrometry (LC/MS/MS). The analytes were separated on an Acquity UPLC HSS T3 column under gradient elution with methanol and 0.01% ammonia solution in 10 mM ammonium acetate/water. This is the first reported method for the determination of TFV using alkaline rather than acidic mobile phases. Linearity, accuracy, precision, limit of quantification, specificity and stability were assessed. RESULTS: Detection of TFV was achieved within 4 min. The calibration curves for TFV quantification showed excellent linearity in the range of 1-500 ng/mL. The intra- and interbatch precision and accuracy ranged from -4.35% to 6.92%. This method was successfully applied to determination of samples from 50 HBV mono-infected women undergoing tenofovir disoproxil fumarate therapy. The mean concentrations of TFV in the umbilical cord and amniotic fluid samples were 29.2 (4.6-86) and 470.9 (156-902) ng/mL, respectively, which showed a moderate positive correlation (r = 0.5299, P<0.001). CONCLUSIONS: A simple, rapid but sensitive bioanalytical method to determine TFV concentration in both umbilical cord plasma and amniotic fluid using LC/MS/MS was developed and applied to HBV-infected women during labor who were undergoing TDF therapy, which will help us understand the efficacy and safety of tenofovir during pregnancy.

RESUMO

BACKGROUND: International sustainable development goals for the elimination of viral hepatitis as a public health problem by 2030 highlight the need to optimize strategies for prevention, diagnosis and treatment of hepatitis B virus (HBV) infection. An important priority for Africa is to have affordable, accessible and sustainable prevention of mother to child transmission (PMTCT) programmes, delivering screening and treatment for antenatal women and implementing timely administration of HBV vaccine for their babies. METHODS: We developed a decision-analytic model simulating 10,000 singleton pregnancies to assess the cost-effectiveness of three possible strategies for deployment of tenofovir in pregnancy, in combination with routine infant vaccination: S1: no screening nor antiviral therapy; S2: screening and antiviral prophylaxis for all women who test HBsAg-positive; S3: screening for HBsAg, followed by HBeAg testing and antiviral prophylaxis for women who are HBsAg-positive and HBeAg-positive. Our outcome was cost per infant HBV infection avoided and the analysis followed a healthcare perspective. RESULTS: Based on 10,000 pregnancies, S1 predicts 45 infants would be HBV-infected at six months of age, compared to 21 and 28 infants in S2 and S3, respectively. Relative to S1, S2 had an incremental cost of $3940 per infection avoided. S3 led to more infections and higher costs. CONCLUSION: Given the long-term health burden for individuals and economic burden for society associated with chronic HBV infection, screening pregnant women and providing tenofovir for all who test HBsAg+ may be a cost-effective strategy for South Africa and other low/middle income settings.

RESUMO

The incidence of congenital syphilis remains low in the UK, but the morbidity and mortality to babies born to women who are untreated for the condition make testing for the disease antenatally one of the most cost-effective screening programmes. Women attending North Middlesex Hospital, UK with a positive syphilis test at their antenatal booking visit are referred to St Ann's Sexual Health Clinic, London, for management and contact tracing. We were concerned that our initial audit revealed that a large proportion of women referred to our service never attended and recorded partner notification was poor. Following the implementation of recommendations, specifically the introduction of an electronic referral system, re-audit showed an improvement in attendance, contact tracing, documentation and communication.

RESUMO

BACKGROUND: This article assessed maternal and neonatal outcomes amongst users of prevention of mother-to-child transmission (PMTCT) of HIV services in Addis Ababa, Ethiopia. OBJECTIVES: The study aimed to assess the health outcomes (antiretroviral prophylaxis versus antiretroviral treatment, CD4 counts, World Health Organization (WHO) stages of illness, other illnesses) of women who had used these services, as well as the HIV status of their babies and the infant feeding method adopted. METHODS: A quantitative, cross sectional, retrospective cohort design was used. Document reviews were conducted with a sample of 384 mother-infant pairs (out of a population of 796) who had used PMTCT services. RESULTS: All respondents were using prophylactic antiretrovirals or antiretroviral therapy, but some were on the wrong treatment based on their CD4 counts. The CD4 counts increased four times more for women on antiretroviral treatment than for those on prophylactic antiretrovirals. The WHO's stages of HIV illness did not improve but deteriorated in some cases, and 52 other illnesses were recorded. Out of the 384 infants, 6.0% (n = 23) were HIV-positive. Most respondents opted for exclusive breast feeding but some used mixed feeding during the first six months of their infants' lives, despite having received health education related to infant feeding options. CONCLUSION: The respondents' improved CD4 counts were inadequate to improve their World Health Organization stages of HIV illness. Some babies received mixed feeding during the first six months of their lives and 6% of the babies were HIV-positive despite their mothers' utilisation of PMTCT services.

RESUMO

OBJECTIVE: Evaluation of a neonate for suspected early neonatal sepsis routinely includes blood tests such as complete blood count, C-reactive protein (CRP) and culture. In order to obviate the need for venepuncture, we prospectively compared these tests in paired samples from umbilical cord and peripheral venous blood drawn during the first hours after birth in both preterm and term infants. METHODS: Paired blood samples were studied from asymptomatic neonates with risk factors for early sepsis. Data were collected on maternal and neonatal factors that may have influenced the correlation between the tests. RESULTS: Three hundred fifty pairs of samples were studied. Significant correlation between umbilical cord and peripheral venous samples was found for white blood cell (WBC; r = 0.683) and platelets (PLT) (r = 0.54). Correlation for hemoglobin was lower (r = 0.36). No cases of early neonatal sepsis were detected. However, contamination rates were 12% in umbilical cord blood and 2.5% in peripheral venous blood cultures. WBC rose after birth and the 90th percentile rose from 22 500 in umbilical cord blood to 29 700 in peripheral blood. CONCLUSIONS: Screening for sepsis with umbilical cord CBC may be useful provided normal ranges are adjusted accordingly.

RESUMO

AIM: Aim of this study was to assess concentrations of interleukin-6 (IL-6), interleukin-8 (IL-8) and interleukin-18 (IL-18) in the serum of newborns with diagnosed intrauterine growth restriction (IUGR) in comparison to concentrations in serum of newborns with weight appropriate for gestational age (AGA). MATERIALS: Research was conducted at the Lodz Medical University Clinic of Neonatology during 2010-2011. Surveyed group consisted of 50 hypotrophic full-term infants of single pregnancies (average weight: 2329 ± 287 g); control group, enclosing 50 infants AGA (average weight: 3544 ± 2161 g). Both groups received average Apgar score of 9 points. Concentrations of analysed cytokines were marked between 4-6 hours after birth. The enzyme-linked immunosorbent assay (ELISA) test was used to determine interleukins concentrations. Study was prospective. Statistics on the data were conducted with the Kolmogorov-Smirnov test. Significance level: p < 0.05. RESULTS: Concentrations of IL-6 and IL-18 were elevated in the IUGR group in a statistically significant manner in comparison to the control group. CONCLUSIONS: An elevated level of IL-6 and IL-18 in the IUGR group, comparing to control group, signifies the existence of inflammation in the process of developing IUGR, therefore, screening tests estimating levels of interleukins as IL-6 and IL-18 might be clinically useful in predicting the occurrence of IUGR and help preventing it.

RESUMO

BACKGROUND: Prevention of mother to child transmission of HIV (PMTCT) has been scaled, to more than 90% of health facilities in Tanzania. Disclosure of HIV results to partners and their participation is encouraged in the program. This study aimed to determine the prevalence, patterns and predictors of HIV sero-status disclosure to partners among HIV positive pregnant women in Morogoro municipality, Tanzania. METHODS: A cross sectional study was conducted in March to May 2010 among HIV-positive pregnant women who were attending for routine antenatal care in primary health care facilities of the municipality and had been tested for HIV at least one month prior to the study. Questionnaires were used to collect information on possible predictors of HIV disclosure to partners. RESULTS: A total of 250 HIV-positive pregnant women were enrolled. Forty one percent (102) had disclosed their HIV sero-status to their partners. HIV-disclosure to partners was more likely among pregnant women who were < 25 years old [Adjusted odds ratio (AOR) = 2.2; 95% CI: 1.2-4.1], who knew their HIV status before the current pregnancy [AOR = 3.7; 95% CI: 1.7-8.3], and discussed with their partner before testing [AOR = 6.9; 95% CI: 2.4-20.1]. Dependency on the partner for food/rent/school fees, led to lower odds of disclosure to partners [AOR = 0.4; 95% CI: 0.1-0.7]. Nine out of ten women reported to have been counseled on importance of disclosure and partner participation. CONCLUSIONS: Six in ten HIV positive pregnant women in this setting had not disclosed their results of the HIV test to their partners. Empowering pregnant women to have an individualized HIV-disclosure plan, strengthening of the HIV provider initiated counseling and testing and addressing economic development, may be some of the strategies in improving HIV disclosure and partner involvement in this setting.

RESUMO

OBJECTIVE: To compare the cost-effectiveness of hepatitis B virus (HBV) control strategies combining universal vaccination with hepatitis B immunoglobulin (HBIG) treatment for neonates of carrier mothers. METHODS: Drawing on Taiwan's experience, we developed a decision-analytic model to estimate the clinical and economic outcomes for 4 strategies: (1) strategy V-universal vaccination; (2) strategy S-V plus screening for hepatitis B surface antigen (HBsAg) and HBIG treatment for HBsAg-positive mothers' neonates; (3) strategy E-V plus screening for hepatitis B e-antigen (HBeAg), HBIG for HBeAg-positive mothers' neonates; (4) strategy S&E-V plus screening for HBsAg then HBeAg, HBIG for all HBeAg-positive, and some HBeAg-negative/HBsAg-positive mothers' neonates. RESULTS: Strategy S averted the most infections, followed by S&E, E, and V. In most cases, the more effective strategies were also more costly. The willingness-to-pay (WTP) above which strategy S was cost-effective rose as carrier rate declined and was <$4000 per infection averted for carrier rates >5%. The WTP below which strategy V was optimal also increased as carrier rate declined, from $1400 at 30% carrier rate to $3100 at 5% carrier rate. Strategies involving E were optimal for an intermediate range of WTP that narrowed as carrier rate declined. CONCLUSIONS: HBIG treatment for neonates of HBsAg carrier mothers is likely to be a cost-effective addition to universal vaccination, particularly in settings with adequate health care infrastructure. Targeting HBIG to neonates of higher risk HBeAg-positive mothers may be preferred where WTP is moderate. However, in very resource-limited settings, universal vaccination alone is optimal.

RESUMO

OBJECTIVES: Peripartal transmission of human immunodeficiency virus (HIV) and Treponema pallidum, the causative agent of syphilis, leads to severe consequences for newborns. Preventive measures require awareness of the maternal infection. Although HIV and syphilis testing in Madagascar could be theoretically carried out within the framework of the national pregnancy follow-up scheme, the required test kits are rarely available at peripheral health centres. In this study, we screened blood samples of pregnant Madagascan women for HIV and syphilis seroprevalence to estimate the demand for systemic screening in pregnancy. METHODS: Retrospective anonymous serological analysis for HIV and syphilis was performed in plasma samples from 1232 pregnant women that were taken between May and July 2010 in Ambositra, Ifanadiana, Manakara, Mananjary, Moramanga and Tsiroanomandidy (Madagascar) during pregnancy follow-up. Screening was based on Treponema pallidum haemagglutination tests for syphilis and rapid tests for HIV, with confirmation of positive screening results on line assays. RESULTS: Out of 1232 pregnant women, none were seropositive for HIV and 37 (3%) were seropositive for Treponema pallidum. CONCLUSIONS: Our findings are in line with previous studies that describe considerable syphilis prevalence in the rural Madagascan population. The results suggest a need for screening to prevent peripartal Treponema pallidum transmission, while HIV is still rare. If they are known, Treponema pallidum infections can be easily, safely and inexpensively treated even in pregnancy to reduce the risk of transmission.

RESUMO

UNLABELLED: The Romanian program for the management and screening of syphilis includes the recording, follow-up, and antenatal care of pregnant women. It aims at testing all pregnant women for syphilis with the help of VDLR (Venereal Disease Research Laboratory) or RPR (Rapid Plasma Reagin) tests, and in the women with positive tests to confirm the results by treponemal tests (treponemal antibodies): THPA (Treponema Pallidum Hemagglutination), FTA-Abs (Fluorescent Treponemal Antibody with Absorption), ELISA-Captia-IgM, and Western Blotting-IgM. In the pregnant women with positive tests two doses of 2.4 million units of penicillin G benzathine were administered at 5 days interval. These pregnant women are in the evidence of a specialist (obstetrician, dermatologist), and District Department of Public Health, and required to come for another serology test in 3 months. In case they still test positive, the same treatment is applied at the beginning of the third trimester of pregnancy. AIM: To assess the outcome of congenital syphilis prevention programs in lasi, Romania. MATERIAL AND METHODS: In the interval 2005-2011, in the Iasi town, 84 RPR positive pregnant women were recorded. There was no significant difference in the number of pregnant women residing in urban as compared to rural areas. Most of these women were from poor social environments and had a low level of education. The diagnosis of acquired syphilis was made by serological tests as most pregnant women presented in the period of syphilis latency, being asymptomatic. All pregnant women followed the treatment, and were tested periodically. Ultrasound examination was normal in all women (no changes suggestive of fetal malformations). RESULTS: Free clinical, laboratory, and ultrasound investigations, history taking, psychological assessment, sex education, rapid identification of contacts of known patients, follow-up of the interaction between health care providers and syphilitic pregnant women, booklets, and leaflets altogether made that in the last 3 years (2008-2010) no new case of congenital syphilis to be reported in the study area. CONCLUSIONS: Encouraging women to attend antenatal care early in their pregnancy is essential, this way all pregnancy-related problems (syphilis included) could be managed.

RESUMO

Concomitant cytomegalovirus infection (CMVI), a classical opportunistic infection, is an important problem among HIV-infection pregnant women. CMVI in pregnant women runs mainly in the latent form with reactivation under physiological immunosuppression. Therefore the evaluation of immunoresponsiveness in HIV-infected pregnant women with mixed (HIV + CMV) infection becomes to be of particular urgency. Sixty-five women who were registered in the antenatal clinic of Surgut and its anti-AIDS center in 2005-2007 were examined. The examinees' sera were tested for CMV antibody titers by heterogenous solid-phase enzyme immunoassay (EIA) to determine the moment of infection and differentiation of primary infection, reinfection, or infectious process reactivation. Assay of plasma CMV DNA was carried out by the polymerase chain reaction technique to evaluate the activity of CMVI. The high spread of serological CMVI markers in the pregnant women of the Middle Ob Region necessitates monitoring this group, by obligatorily determining IgM, IgG, and their avidity.

RESUMO

OBJECTIVES: On-site screening and same-day treatment of maternal syphilis in underresourced settings can avert greater numbers of congenital syphilis cases, but health outcomes and associated costs must be evaluated jointly. METHODS: We used decision analysis to estimate the incremental cost-effectiveness of two on-site antenatal syphilis screening strategies to avert congenital infections-qualitative RPR (on-site RPR) and treponemal immunochromatographic strip assay (on-site ICS)-compared to the current practice (off-site RPR/TPHA). FINDINGS: With antenatal active syphilis prevalence of 6.3%, the incremental cost-effectiveness of on-site ICS in averting congenital infections was estimated to be USD104, averting 82% of cases expected in absence of a program. The incremental cost-effectiveness of off-site RPR/TPHA was USD82 but would avert only 55% of congenital syphilis cases. On-site RPR was dominated by the other screening strategies. CONCLUSIONS: In settings of high maternal syphilis prevalence, on-site antenatal screening with ICS is a cost-effective approach to reduce the incidence of congenital syphilis.

RESUMO

OBJECTIVES: Congenital syphilis is a significant cause of adverse pregnancy outcomes. In South Africa, rural clinics perform antenatal screening offsite, but unreliable transport and poor client follow up impede effective treatment. We compared 3 syphilis screening strategies at rural clinics: on-site rapid plasma reagin (RPR), on-site treponemal immunochromatographic strip (ICS) test, and the standard practice offsite RPR with Treponema pallidum hemagglutination assay (RPR/TPHA). METHODS: Eight rural clinics performed the on-site RPR and ICS tests and provided immediate treatment. Results were compared with RPR/TPHA at a reference laboratory. Chart reviews at 8 standard practice clinics established diagnosis and treatment rates for offsite RPR/TPHA. FINDINGS: Seventy-nine (6.3%) of 1,250 women screened on-site had active syphilis according to the reference laboratory. The on-site ICS resulted in the highest percentage of pregnant women correctly diagnosed and treated for syphilis (89.4% ICS, 63.9% on-site RPR, 60.8% offsite RPR/TPHA). The on-site RPR had low sensitivity (71.4% for high-titer syphilis). The offsite approach suffered from poor client return rates. One percent of women screened with the ICS may have received penicillin unnecessarily. There were no adverse treatment outcomes. CONCLUSIONS: The on-site ICS test can reduce syphilis-related adverse outcomes of pregnancy through accurate diagnosis and immediate treatment of pregnant women with syphilis.
