Objectives To evaluate prevention of mother to child transmission of HIV (PMTCT) implementation and integration of PMTCT with routine maternal and child health services in two districts of KwaZulu‐Natal; to report PMTCT coverage, to compare recorded and reported information, and to describe responsibilities of nurses and lay counsellors. Methods Interviews were conducted with mothers in post‐natal wards (PNW) and immunisation clinics; antenatal and child health records were reviewed. Interviews were conducted with nurses and lay counsellors in primary health care clinics. Results Eight hundred and eighty‐two interviews were conducted with mothers: 398 in PNWs and 484 immunisation clinics. During their recent pregnancy, 98.6% women attended antenatal care (ANC); 60.8% attended their first ANC in the third trimester, and 97.3% were tested for HIV. Of 312 mothers reporting themselves HIV positive during ANC, 91.3% received nevirapine, 78.2% had a CD4 count carried out, and 33.1% had a CD4 result recorded. In the immunisation clinic, 47.6% HIV‐exposed babies had a PCR test, and 47.0% received co‐trimoxazole. Of HIV‐positive mothers, 42.1% received follow‐up care, mainly from lay counsellors. In 12/26 clinics, there was a dedicated PMTCT nurse, PCR testing was not offered in 14/26 clinics, and co‐trimoxazole was unavailable in 13/26 immunisation clinics. Nurses and lay counsellors disagreed about their roles and responsibilities, particularly in the post‐natal period. Conclusions There is high coverage of PMTCT interventions during pregnancy and delivery, but follow‐up of mothers and infants is poor. Poor integration of PMTCT services into routine care, lack of clarity about health worker roles and poor record keeping create barriers to accessing services post‐delivery. 相似文献

OBJECTIVE: Previous studies on the operational effectiveness of programmes to reduce transmission of HIV from mother-to-child (PMTCT) in Africa have generally been hospital-based pilot studies with short follow-up periods. METHOD: Prospective cohort study to evaluate the routine operational effectiveness of the South African National PMTCT Programme, primarily measured by HIV-free survival at 36 weeks post-delivery. Three of eighteen pilot sites participating in the programme were selected as they reflected differences in circumstances, such as HIV prevalence, socioeconomic status and rural-urban location. A total of 665 HIV-positive mothers and their infants were followed. RESULTS: HIV-free survival at 36 weeks varied significantly across sites with 84% in Paarl, 74% in Umlazi and 65% in Rietvlei (P = 0.0003). Maternal viral load was the single most important factor associated with HIV transmission or death [hazard ratio (HR), 1.54; 95% confidence interval (CI), 1.21-1.95]. Adjusting for health system variables (fewer than four antenatal visits and no antenatal syphilis test) explained the difference between Rietvlei and Paarl (crude HR, 2.27; 95% CI, 1.36-3.77; adjusted HR, 1.81; 95% CI, 0.93-3.50). Exposure to breastmilk feeding explained the difference between Umlazi and Paarl (crude HR, 1.74; 95% CI, 1.06-2.84; adjusted HR, 1.41; 95% CI, 0.81-2.48). CONCLUSION: Ever breastfeeding and underlying inequities in healthcare quality within South Africa are predictors of PMTCT programme performance and will need to be addressed to optimize PMTCT effectiveness. 相似文献

A pilot prevention of mother-to-child transmission (PMTCT) programme was implemented in Constanta County, Romania, between 2000 and 2002. The programme consisted of clinician training, routine antenatal HIV counselling and testing and the care of HIV-infected pregnant women and their infants. A total of 11,423 pregnant women (10,192 (89%) white Europeans, 862 (7.5%) Rroma, 369 (3.2%) Central Asians) were tested during the pilot, at a median of 24 weeks' gestation. Rapid HIV testing at delivery was introduced during the pilot, to supplement the antenatal testing, both of which required informed consent. Overall seroprevalence was 1.75 per 1,000 (95% confidence interval (CI) 1.07-2.70 per 1,000). HIV infection was associated with having a high-risk partner, prostitution and non-Caucasian ethnicity. Twelve infected women completed their pregnancies, of whom seven received antenatal antiretroviral therapy (ART); all neonates received prophylactic ART and five were delivered by elective caesarean section. Three infants were HIV-infected, giving a vertical transmission rate of 25% (95% CI 5.49-57.2%); all three were born to mothers not identified as infected until delivery, and who therefore received no antenatal ART. A key challenge for PMTCT in Romania will be the prompt identification of pregnant HIV-infected women, to allow the optimum application of interventions. 相似文献

Prevention of mother-to-child transmission of HIV (PMTCT) is a foundational component of a comprehensive HIV treatment program. In addition to preventing vertical transmission to children, PMTCT is an important catch-point for universal test-and-treat strategies that can reduce community viral load and slow the epidemic. However, systematic reviews suggest that care engagement in PMTCT programs is sub-optimal. This study enrolled a cohort of 200 women initiating PMTCT in Kilimanjaro, Tanzania, and followed them to assess HIV care engagement and associated factors. Six months after delivery, 42/200 (21%) of participants were identified as having poor care engagement, defined as HIV RNA >200?copies/mL or, if viral load was unavailable, being lost-to-follow-up in the clinical records or self-reporting being out of care. In a multivariable risk factor analysis, younger women were more likely to have poor postpartum care engagement; with each year of age, women were 7% less likely to have poor care engagement (aRR: 0.93; 95% CI: 0.89, 0.98). Additionally, women who had told at least one person about their HIV status were 47% less likely to have poor care engagement (aRR: .53; 95% CI: 0.29, 0.97). Among women who entered antenatal care with an established HIV diagnosis, those who were pregnant for the first time had increased risk of poor care engagement (aRR 4.16; 95% CI 1.53, 11.28). The findings suggest that care engagement remains a concern in PMTCT programs, and must be addressed to realize the goals of PMTCT. Comprehensive counseling on HIV disclosure, along with community-based stigma reduction programs to provide a supportive environment for people living with HIV, are crucial to address barriers to care engagement and support long-term treatment. Women presenting to antenatal care with an established HIV status require support for care engagement during the crucial period surrounding childbirth, particularly those pregnant for the first time. 相似文献

BACKGROUND: Clinical signs and symptoms of acute human immunodeficiency virus (HIV) infection in infants are not well characterized. METHODS: Serial clinical assessments and HIV PCR assays were conducted in a cohort of children born to HIV-seropositive mothers from birth to 2 years of age. Acute HIV infection visits were defined as those up to 3 months prior to and including the visit at which HIV DNA was first detected. Noninfection visits included all visits at which the child had test results negative for HIV, including the last visit at which a test result negative for HIV DNA was obtained in children who later acquired HIV infection. Differences in the prevalence of symptoms at acute infection versus noninfection visits were determined overall and were stratified by age at infection (<2 months vs. >or=2 months). HIV RNA was measured serially in infected infants and was compared between infants with and infants without symptoms of acute HIV infection. RESULTS: There were 125 acute infection visits (among 56 infants) and 3491 noninfection visits (among 306 infants). Acute HIV infection was associated with rash (odds ratio [OR], 1.8; 95% confidence interval [CI], 1.1-2.8), failure to thrive (OR, 1.9; 95% CI, 1.0-3.5), and lymphadenopathy (OR, 2.5; 95% CI, 1.4-4.8). Acute HIV infection was associated with lymphadenopathy (OR, 2.6; 95% CI, 1.3-5.0) in infants <2 months of age and with pneumonia (OR, 3.2; 95% CI, 1.1-9.3) and dehydration (OR, 6.0; 95% CI, 1.9-18.5) in infants >or=2 months of age. Infant peak viral load and mortality were not associated with symptoms of acute HIV infection. However, infants with symptoms had higher viral levels later in the course of infection than did those without symptoms (P=.05). CONCLUSIONS: Infants may manifest symptoms early during the course of HIV infection, and symptoms of acute HIV infection may correlate with poor viral control. Rash, failure to thrive, lymphadenopathy, pneumonia, and dehydration may signify acute HIV infection in infants. 相似文献

Prevention of mother-to-child transmission (PMTCT) programs are considered as an entry point to continued care because they provide an opportunity to link an HIV-infected woman, her partner, and child(ren) (if infected) to long-term treatment and care. However, little is known about the factors associated with the utilization of continued care among women who have previously accessed PMTCT services. Better knowledge of the barriers to continued care in HIV-infected women could lead to effective strategies to increase the uptake of post-PMTCT care. This study was designed to examine the factors associated with the utilization of continued care among HIV-infected women enrolled in the PRAYAS PMTCT program in Maharashtra, India, between 2002 and 2011. All consenting women who had completed the receipt of PMTCT services or who were lost to follow-up at least six months prior to the time of data collection were interviewed. Univariate and multivariate analyses were conducted to estimate the associations between not utilizing continued care and hypothesized risk factors using generalized linear models. Of the 688 eligible HIV-positive women, 311 completed a structured interview. Since their exit from the PMTCT program, 59 (19%) had never utilized HIV-related care, 58 (19%) had intermittently utilized HIV-related care, and 194 (62%) had consistently utilized HIV-related care at regular intervals. After adjusting for potential confounders, women with poor HIV-related knowledge (relative risk [RR] = 1.83; 95% CI: 1.15–2.92), women whose partners had never utilized HIV-related care (RR = 4.82; 95% CI: 2.57–9.04), and women who could not afford to travel to the HIV-care facility (RR = 2.36; 95% CI: 1.23–4.53) were less likely to utilize HIV-related care after exiting the PMTCT program. This study highlights the need for enhanced techniques to impart HIV and antiretroviral therapy-related knowledge and underlines the need for improved partner involvement and financial support for travel to HIV facility to increase the uptake of post-PMTCT treatment and care. 相似文献

Summary. Acute hepatitis C virus (HCV) infection may lead to chronic HCV‐infection with detectable HCV RNA or to spontaneous clearance with no HCV RNA, but detectable HCV antibodies. It is unknown whether HCV RNA status is associated with mortality in HIV‐infected injection drug users (IDUs). We conducted a nationwide population‐based cohort study to examine the impact of HCV RNA status on overall and cause‐specific mortality in HIV‐infected IDUs. We computed cumulative mortality and used Cox Regression to estimate mortality rate ratios (MRR). We identified 392 HIV‐infected patients of whom 284 (72%) had chronic HCV‐infection (HCV RNA positive patients) and 108 (28%) had cleared the HCV‐infection (HCV RNA negative patients). During 1286 person‐years of observation (PYR), 157 persons died (MR = 122/1000 PYR, 95% CI: 104–143). The estimated 5‐year probabilities of survival were 0.58 (95% CI: 0.51–0.65) in the chronically HCV‐infected and 0.52 (95% CI: 0.40–0.63) in the cleared HCV group. Chronic HCV‐infection was not associated with overall mortality: MRR 0.85, 95% CI: 0.59–1.21. In HIV‐infected Danish IDUs, chronic HCV‐infection is not associated with increased mortality compared to patients who have cleared the infection. 相似文献

Despite the effectiveness of antiretroviral therapy (ART) in the prevention of mother-to-child transmission of HIV (PMTCT), some HIV-infected women in PMTCT care are at risk of transmitting HIV to their babies. Using a 1:1 unmatched case–control study design, we assessed the risk factors for perinatal transmission among women who received ART for PMTCT in Sokoto State, Nigeria. Data were abstracted from medical records of cases (94 HIV-infected babies) and controls (94 HIV-uninfected babies) and their mothers who accessed PMTCT services in three purposefully selected secondary health facilities. We conducted univariate and multivariate logistic regressions to determine if sociodemographic characteristics, time of enrolment, type of maternal ART, receipt of infant antiretroviral (ARV) prophylaxis, place of delivery, or feeding practice were associated with HIV infection among HIV-exposed babies. Sixteen percent of the mothers of babies in the case group had early enrolment while 90% of those in the control group enrolled early. Infant prophylaxis was received in 54% of cases and 95% of controls. In both groups, 99% of the mothers practiced mixed feeding. In the univariate analysis, factors that were significantly associated with HIV infection were religion (islam), rural residence, late? enrolment, and non-receipt of infant ARV prophylaxis. In the multivariate analysis, rural residence (Adjusted odds ratio (aOR)?=?8.01, 95% CI?=?1.79–35.78), late enrolment (aOR?=?41.72, 95% CI?=?15.16–114.79), and non-receipt of infant ARV prophylaxis (aOR?=?4.1, 95% CI?=?1.18–14.33) remained statistically significant. Findings from this study indicate that eliminating MTCT in Nigeria requires interventions that will enhance timely access of ART by mother-baby dyads. 相似文献

Greenland is a high-income country with free access to human immunodeficiency virus (HIV) care, including highly active antiretroviral therapy (HAART). We aimed to examine the HIV prevalence, age and gender distribution, and the effectiveness of HAART on CD4 positive cell count, viral load (VL), and mortality in the Greenland HIV-infected population. In this population-based cohort study we collected demographic, clinical and biochemical data on all HIV-infected patients followed in health clinics since 1995. For each case, we identified 100 age- and gender-matched population controls. The HIV cohort included 103 patients of whom 91% were Inuit; 81% were infected heterosexually. Only 40% of the patients had a VL <400 copies/ml at 48 weeks after starting HAART, and patients on HAART had a substantial excess relative mortality compared with the general population (mortality rate ratio [MRR]: 10.6; 95% confidence interval [CI]: 6.9-16.4). After the introduction of HAART, the mortality decreased (MRR: 2.5; 95% CI 0.9-6.8), but remained high with a mortality rate of 62 per 1000 person-years (py) (95% CI 29-129). Our findings underline the difficulties of implementing successful HIV treatment even with unlimited economic resources and free access to health care. 相似文献

BACKGROUND: Prolonged coinfection with GB virus C (GBV-C) has been associated with improved survival in human immunodeficiency virus (HIV)-infected adults. We investigated whether maternal or infant GBV-C infection was associated with mother-to-child transmission (MTCT) of HIV-1 infection. METHODS: The study population included 1364 HIV-infected pregnant women enrolled in 3 studies of MTCT of HIV in Bangkok, Thailand (the studies were conducted from 1992-1994, 1996-1997, and 1999-2004, respectively). We tested plasma collected from pregnant women at delivery for GBV-C RNA, GBV-C antibody, and GBV-C viral genotype. If GBV-C RNA was detected in the maternal samples, the 4- or 6-month infant sample was tested for GBV-C RNA. The rates of MTCT of HIV among GBV-C-infected women and infants were compared with the rates among women and infants without GBV-C infection. RESULTS: The prevalence of GBV-C RNA in maternal samples was 19%. Of 245 women who were GBV-C RNA positive, 101 (41%) transmitted GBV-C to their infants. Of 101 infants who were GBV-C RNA positive, 2 (2%) were infected with HIV, compared with 162 (13%) of 1232 infants who were GBV-C RNA negative (odds ratio [OR] adjusted for study, 0.13 [95% confidence interval {CI}, 0.03-0.54]). This association remained after adjustment for maternal HIV viral load, receipt of antiretroviral prophylaxis, CD4(+) count, and other covariates. MTCT of HIV was not associated with the presence of GBV-C RNA (adjusted OR [aOR], 0.94 [95% CI, 0.62-1.42]) or GBV-C antibody (aOR, 0.90 [95% CI, 0.54-1.50]) in maternal samples. CONCLUSIONS: Reduced MTCT of HIV was significantly associated with infant acquisition of GBV-C but not with maternal GBV-C infection. The mechanism for this association remains unknown. 相似文献

Exclusively breastfed infants in developing countries are at lower risk of HIV transmission than mixed-fed infants. Ethno-graphic research was conducted in eleven low-resource settings across South Africa, Namibia and Swaziland to understand how the perceptions and experiences of counselling health workers, pregnant women and recent mothers could be used to improve infant feeding counselling. Despite prevention of mother-to-child transmission (PMTCT) programmes, very early mixed-feeding remains the norm; traditional conceptualisations of 'water as life' and 'milk as a fluid' are holding up against current PMTCT education, with milk considered liquid 'drink' rather than 'real food'. This aggravates an 'insufficient milk syndrome' where disempowered mothers perceive their breastmilk, and themselves, as deficient - 'not good enough'. Infant feeding is embedded within traditional relationships of intimacy; both relatives and breadwinner have influence and even authority over options and modes of infant feeding. In patriarchal and violent societies, traditional power differentials prohibit easy or complete HIV disclosure or condom negotiation; HIV status remains hidden from most partners and relatives. This context of secrecy means that the traditional advice and authority, which the mothers feel they dare not disregard, is often blind to the mother and her infant's HIV status and survival needs. 相似文献

To compare HIV prevalence measured by antenatal clinics (ANC) sentinel surveillance and by the prevention of mother-to-child transmission (PMTCT) program in Rwanda. We compared HIV prevalence from anonymous testing performed under ANC surveillance, and that measured from voluntary counselling and testing performed under the PMTCT program, in a random sample of the same population of pregnant women attending for their first antenatal visit at 29 ANC surveillance sites with a PMTCT program in 2007 in Rwanda. All of the 13,318 pregnant women recruited in the ANC surveillance accepted to participate in the PMTCT program. HIV prevalence measured by sentinel surveillance was 4.35% whereas that measured for 1873 pregnant women (out of the total sentinel population) by the PMTCT program was 3.49% (p=0.07). For 3% of the PMTCT population, HIV test results were missing from the counselling logbook versus 0.3% in the ANC laboratory logbooks. For 10 pregnant women, HIV test results were divergent between the PMTCT and the ANC laboratory logbooks. After missing data and errors were corrected, HIV prevalence results from PMTCT was 3.27% (significantly different from ANC surveillance: p =0.03). High uptake of PMTCT program among pregnant women was observed in Rwanda in 2007. HIV prevalence measured by the ANC surveillance and PMTCT program were significantly different. Poor performance in HIV testing practices and PMTCT/laboratories data management could explain this difference. Improvement in HIV testing practices and in PMTCT/laboratory data management are needed in order to use PMTCT data for HIV surveillance and to ensure good performance of all the package of care provided by the PMTCT program. 相似文献

Objectives To assess the availability of equipment and the staff’s knowledge to prevent Mother‐To‐Child Transmission (PMTCT) in rural healthcare facilities recently covered by the national PMTCT programme in Cameroon. Methods In eight districts inventories of antiviral drugs and HIV test kits were made on site, using a standardised check‐list. Knowledge of HIV and PMTCT was evaluated with a multiple‐choice (MC) questionnaire based on typical clinical PMTCT cases. Staff participated subsequently in a 2‐day training on HIV/AIDS and the Cameroon PMTCT guidelines. Immediately after training and after 7 months, retention of knowledge was tested with the same questions but in different order and layout. Results Sixty two peripheral nurse‐led clinics and the eight district hospitals were assessed. Whereas all district hospitals presented complete equipment, only six of the peripheral clinics (10%) were equipped with both complete testing materials and a full set of drugs to provide PMTCT. Thirty six peripheral facilities (58%) possessed full equipment for HIV‐testing and 8 (13%) stocked all PMTCT drugs. Of 137 nurses, 102 (74%) agreed to the two knowledge tests. Fewer than 66% knew that HIV‐diagnosis requires positive results in two different types of rapid tests and only 19% chose the right recommendation on infant‐feeding for HIV‐positive mothers. Correct answers on drug regimens in different PMTCT settings varied from 25% to 56%. All percentages of correct answers improved greatly with training (P < 0.001) and retention remained high 7 months after training (P < 0.001). Conclusions Prevent Mother‐To‐Child Transmission programmes in settings such as rural Cameroon need to be adapted to the special needs of peripheral nurse‐led clinics. Appropriate short training may considerably improve nurses’ competence in PMTCT. Other important components are regular supervision and measures to guarantee supply of equipment in rural areas. 相似文献

BACKGROUND: The goal of the present study was to assess risk factors for perinatal hepatitis C virus (HCV) transmission and the natural history of infection among HCV-infected infants. METHODS: In a cohort study, 244 infants born to HCV-positive mothers were followed from birth until age > or =12 months. Maternal serum was collected at enrollment and delivery; infant serum was collected at birth and at 8 well-child visits. Testing included detection of antibody to HCV, detection of HCV RNA (qualitative and quantitative), and genotyping. HCV-infected infants were followed annually until age 5 years. RESULTS: Overall, 9 of 190 (4.7% [95% confidence interval (CI), 2.3%-9.1%]) infants born to mothers who were HCV RNA positive at delivery became infected, compared with 0 of 54 infants born to HCV RNA-negative mothers (P=.10). Among HCV RNA-positive mothers, the rate of transmission was 3.8% (95% CI, 1.7%-8.1%) from the 182 who were human immunodeficiency virus (HIV) negative, compared with 25.0% (95% CI, 4.5%-64.4%) from the 8 who were HIV positive (P<.05). Three infected infants resolved their infection (i.e., became HCV RNA negative). In multivariate analysis restricted to HCV RNA-positive mothers, membrane rupture > or =6 h (odds ratio [OR], 9.3 [95% CI, 1.5-179.7]) and internal fetal monitoring (OR, 6.7 [95% CI, 1.1-35.9]) were associated with transmission of HCV to infants. CONCLUSION: If duration of membrane rupture and internal fetal monitoring are confirmed to be associated with transmission, interventions may be possible to decrease the risk of transmission. 相似文献

Progress towards achievement of global targets for the prevention of mother-to-child transmission of HIV (PMTCT) and paediatric HIV care and treatment is an integral part of global and national HIV and AIDS responses. This paper documents the development of the global and national monitoring and reporting systems for PMTCT and paediatric HIV care and treatment programmes, achievements and remaining challenges. A review of the development of the monitoring and reporting process since 2002–2016 was conducted using existing published literature and taking into account changes in WHO HIV treatment guidelines, global HIV goals and targets, programmatic and methodological developments, and increased need for interagency partnerships, coordination and harmonization of global monitoring and reporting mechanisms. The number and type of indicators reported increased and evolved from monitoring of existence of national policies and guidelines, service delivery sites and trained health workers and coverage of PMTCT and paediatric HIV interventions to measuring outcomes and impact in reducing new HIV infections and AIDS related deaths, including efforts to validate elimination of mother-to-child transmission of HIV. These changes were required to mirror changes in WHO and national PMTCT and HIV treatment guidelines. The number of countries reporting PMTCT coverage increased from 53 in 2003 to over 130 in 2015. National monitoring processes have also expanded in scope and the capacity to report on disaggregated data by type of ARV regimen and for paediatric HIV care and treatment has increased. Monitoring of PMTCT and paediatric HIV programmes has contributed a rich body of evidence that helped monitor how quickly countries were adopting and implementing the latest WHO HIV treatment guidelines for pregnant and breastfeeding women and children. The reported data and experiences were instrumental in shaping global policies, national programmes, and investment choices. 相似文献

OBJECTIVE: To determine the association between maternal syphilis and HIV mother-to-child transmission (MTCT). DESIGN: Prospective cohort study. METHODS: Pregnant women admitted at Queen Elizabeth Central Hospital (Malawi) in late third trimester were screened for HIV (by HIV rapid tests) and syphilis (by rapid plasma regain test and Treponema pallidum hemagglutination assay). HIV-infected women and their infants received nevirapine, according to the HIVNET 012 protocol. They were followed up at 6 and 12 weeks postpartum. Infant HIV infection was diagnosed by DNA PCR. FINDINGS: Of the 1155 HIV-infected women enrolled, 1147 had syphilis test results, of whom 92 (8.0%) were infected. Only 751 HIV-positive women delivered live singleton infants who were tested for HIV at birth. Of these, 65 (8.7%) were HIV-infected, suggesting in utero (IU) HIV MTCT. Of the 686 infants who were HIV-negative at birth, 507 were successfully followed up. Of these, 89 (17.6%) became HIV-infected, suggesting intrapartum/postpartum (IP/PP) HIV MTCT. Maternal syphilis was associated with IU HIV MTCT, after adjusting for maternal log10 HIV-1 viral load and low birth weight (LBW) [adjusted relative risk (ARR), 2.77; 95% CI, 1.40-5.46]. Furthermore, maternal syphilis was associated with IP/PP HIV MTCT (ARR, 2.74; 95% CI, 1.58-4.74), after adjusting for recent fever, breast infection, LBW and maternal log10 HIV-1 viral load. CONCLUSION: Maternal syphilis is associated with IU and IP/PP HIV MTCT. Screening and early treatment of maternal syphilis during pregnancy may reduce pediatric HIV infections. 相似文献

Feminization of the HIV epidemic in India has increasingly burdened the public health infrastructure to provide prevention of mother-to-child transmission (PMTCT) services. A mere 20% of pregnant women in the country receive HIV counseling and testing. One of the strategies, for expansion of PMTCT services is to ascertain an accurate identification of HIV-positive pregnant women. Thus, we sought to characterize a demographic profile of pregnant women at high-risk for HIV infection. We performed a retrospective case-control study. We included as cases, all HIV-positive women identified in a PMTCT program implemented in 23 charitable faith-based hospitals in four states in South India over a period of 75 months, starting in January 2003. Thus a total of 320 HIV-positive cases were frequency matched using stratified random sampling to 365 HIV-negative pregnant women presenting for antenatal care during the same time period. Cases and controls were compared using Chi-square test for categorical variables and Student's t-test for continuous variables. Multivariate step-wise logistic regression analysis was performed. On multivariate analysis, following factors were independently predictive of HIV positivity: age ≤25 years (odds ratio [OR] 0.50; confidence interval [CI] 0.33-0.76; p = 0.001); illiteracy (OR 4.89; CI 2.79-8.57; p <0.0001); woman holding a service and/or professional job (OR 0.27; CI 0.14-0.53; p <0.0001); spouses holding a service or higher job (OR 3.13; CI 2.13-4.59; p <0.0001); being married ≤5 years (OR 2.89; CI 1.68-4.95; p <0.0001); late gestational age at presentation (OR 3.06; CI 2.04-4.59; p <0.0001); history of fetal and/or live born loss (OR 2.36; CI 1.51-3.67; p <0.0001). To our knowledge this is the first large study to evaluate factors predictive of HIV positivity among women presenting for antenatal care in the Indian setting. This type of profiling of HIV-positive pregnant women may help expand PMTCT services in a focused and cost-effective manner in India. 相似文献

BACKGROUND: In 2000, Thailand implemented a national program to prevent mother-to-child HIV transmission (PMTCT). OBJECTIVE: To describe the effectiveness of the prevention of mother-to-child HIV transmission program in Thailand. DESIGN AND METHODS: A register of HIV-exposed children at birth was created with follow-up of infection status. The register included children born to HIV-infected women between 1 January 2001 and 31 December 2003 at 84 public health hospitals in six provinces of Thailand. The main outcome measure was HIV infection in children. RESULTS: A total of 2200 children born to HIV-infected mothers were registered. Of these mother-infant pairs, 2105 (95.7%) received some antiretroviral prophylaxis, including 1358 (61.7%) who received the complete short-course zidovudine regimen during pregnancy and labor for the mother and after birth for the infant, with or without other antiretrovirals. HIV infection outcome was determined for 1667 (75.8%) children, of whom 158 [9.5%, 95% confidence interval (CI), 8.1-11.0%] were infected. Transmission risk was 6.8% (95% CI 5.2-8.9%) among 761 mother-infant pairs that received the complete zidovudine regimen alone, and 3.9% (95% CI, 2.2-6.6%) among 361 mother-infant pairs that received the complete zidovudine regimen combined with other antiretrovirals, usually nevirapine. The overall transmission risk from this cohort, including all antiretroviral prophylaxis combinations, is estimated to be 10.2%. CONCLUSIONS: The Thai national PMTCT program is effective in reducing mother-to-child transmission risk from the historical risk of 18.9-24.2%. The addition of nevirapine to short-course zidovudine beginning in 2004 may further improve program effectiveness in Thailand. 相似文献
