Prevention of Mother-to-Child Transmission of HIV: Experience of a Level 2 Health Center in Senegal

The elimination of vertical transmission of HIV from mother to child is a major global goal. In Senegal, the transmission rate was estimated at 3.2% in 2017. To reduce or even eliminate this transmission, Senegal has implemented various strategies and programs adopted and applied nationally. Thus access to services for the prevention of mother-to-child transmission of HIV has been extended to the level of the health post (the lowest level of the country’s health pyramid) with a delegation of tasks to paramedical staff (nurse, midwife) in the diagnosis and therapeutic management. Objectives: To describe the epidemiological profile of HIV (Human Immunodeficiency Virus)-positive mothers, to assess the care of children born to HIV-positive mothers, to determine the rate of HIV transmission from mother to child. Patients and Method: We carried out a retrospective, cross-sectional and descriptive study of all live newborns of HIV-positive mothers who gave birth at the Gaspard Kamara Health Center (a level 2 health center in Dakar, Senegal) between January 1, 2015 and December 31, 2018. The data were collected from prevention of mother-to-child transmission (PMTCT) prenatal follow-up registers and files, delivery files and registers, and neonatology and pediatric follow-up files, and exploited using the Epi info 7 software. Results: There were 98 children of seropositive mothers. The epidemiological profile of the HIV-positive woman was that of a young woman aged between 16 and 43 with an average of 31.31 years, pauciparous (>65% of cases) from Dakar center (>75% of cases), housewife with a low socio-economic level (63.1% of cases), married in almost all cases, with HIV profile (in almost all cases) and diagnosed before pregnancy (51.02%). The analysis of the children’s data revealed a predominance of girls (52.04%) with a good birth weight (2964g on average) and a pregnancy carried to term in more than 95% of cases. ARV prophylaxis was almost entirely respected with triple therapy (AZT + 3TC + NVP) in a fixed combination as protocol. Protected breastfeeding (80.21%), including 6 months of exclusive protected breastfeeding, was the rule for the mode of feeding. Three children were diagnosed positive with PCR1 as with serology (3.06%). Discussion and Conclusion: the initiatives and strategies put in place in Senegal have enabled a significant reduction in mother-to-child transmission of HIV and deserve to be supported by insisting on primary prevention, programming and good follow-up of pregnancies, and a good support for HIV-positive women.

Experiences of Mothers on the Utilization of Elimination of Mother to Child Transmission of HIV Services at Mtendere Clinic, Lusaka

Introduction: Acquired immunodeficiency syndrome is one of the leading causes of mortality among women of reproductive age and Mother to Child Transmission of Human immunodeficiency virus is still a challenge affecting many countries. Globally, an estimation of 180,000 children under 15 years acquire the Human immunodeficiency virus every day, and more than 90% of those infections are due to Mother to Child Transmission. The study sought to explore the experiences of mothers on the Elimination of Mother to Child Transmission-HIV services at Mtendere Clinic, Lusaka. Materials and Methods: Qualitative interpretive phenomenology study design was employed using in-depth interviews to collect data from a sample that was selected using purposive sampling technique. Thirteen participants were recruited, and these were HIV-positive mothers at least between the ages of 15 and 49 years and enrolled in the Elimination of Mother To Child Transmission-HIV program. The in-depth interviews were audiotape recorded and transcribed verbatim. Data was analyzed using thematic method. Findings: Three main themes that emerged are;living with HIV, support system and barriers to utilization of Elimination of Mother To Child Transmission-HIV services. Most of the participants expressed having acquired knowledge from the program, and received counselling and support from spouses, family as well as health personnel at Mtendere health facility which culminated into a positive experience and enhanced their uptake of the Elimination of Mother to Child Transmission-HIV services. However, barriers to service utilization were identified and these included fear of stigma, negative attitudes from health workers, long waiting times, lack of support and lack of transport to the health facility. Conclusion: Interventions such as community awareness campaigns on Elimination of Mother To Child Transmission-HIV, male involvement and implementing mother-to-mother peer support strategies in Elimination of Mother To Child Transmission-HIV service utilization should be prioritized so as to alleviate stigma and enhancing a positive experience for these mothers thus reducing on the Mother to Child HIV Transmission burden and mortality rates.

Status Report on the Elimination of Mother-to-Child Transmission (EMCT) of HIV at the Pikine National Hospital Center (CHNP), Dakar/Senegal

Introduction: For several years, the fight against the human immunodeficiency virus (HIV) has been a major public health issue in Africa. Since 2012, Senegal has adopted WHO option B+, consisting of systematic triple therapy for HIV-positive pregnant women, combined with breastfeeding and antiretroviral (ARV) prophylaxis for exposed newborns. It is in this dynamic that we set ourselves the objectives of evaluating the rate of transmission of HIV from mother to child and taking stock of the monitoring of children born to HIV-positive mothers at the Pediatric Department of the CHN of Pikine located in the Dakar suburbs. Methodology: Thus, we conducted a descriptive and analytical cross-sectional cohort follow-up study from 11/25/2014 to 03/09/2022 including all children born to HIV-positive mothers followed at the Pikine CHN since the start of care. Results: We had collected 51 children exposed to HIV and followed in our structure. They were exposed to HIV1 in 92% of cases. The HIV status of the mothers was known before pregnancy in more than half of the cases. The couples were serodiscordant in 56% of cases. The mothers were in clinical stage 1 of the disease in 69.6% of cases and were already under treatment in 47% of cases. The most used treatment regimen was ATRIPLA with Tenofovir (TDF) + Emtracitabine (FTC) + Efavirenz (EFV) in 59% of cases. Compliance was good in the majority of cases. The CD4 count during pregnancy was low in 10.6% of cases. The pregnancy was well followed in only 36.2% of cases. The mothers had given birth in our structure in 91.4% of cases. The vaginal route was found in 72.5% of cases and delivery was carried out by a midwife in 69.4% of cases. The average birth weight was 2733 ± 564. The majority of newborns had received antiretroviral (ARV) prophylaxis after birth, half of them between 12 and 24 hours. The most used therapeutic protocol was Zidovudine (AZT) + Lamivudine (3TC) + Lopinavir/Ritonavir (LPV/r). Protected breastfeeding was the option chosen in 76.8% of cases. The PCR performed at 6 weeks was negative in more than half of the cases. Retroviral serology was carried out after 14 months in 43% of cases. We noted a single positive case with a negative initial PCR, representing an overall transmission rate of 1.96%. Conclusion: Senegal’s current policy targeting EMTCT of HIV is on good momentum with a fairly low transmission rate thanks to screening of pregnant women and prophylaxis with antiretrovirals (ARV) for HIV-positive mothers during pregnancy and for life. And children exposed from birth and during breastfeeding up to 6 weeks with regular monitoring.

Estimating the Health and Economic Outcomes of the Prevention of Mother-to-child Transmission of HIV Using a Decision Tree Model

In 2016, there were 17.8 million (15.4-20.3 million) women living with HIV/AIDS across the world and the prevalence of reproductive desire among this group was 26%-49%[1]. If pregnant women living with HIV/AIDS are left untreated, the rates of HIV transmission from mother-to-child would range from 14% to 48%, depending on the presence and duration of breastfeeding[2].

Missed Prevention of Mother-to-Child Transmission of HIV (PMTCT) Visits and Associated Programmatic Predictors: A Pilot Study

Missed Prevention of Mother-to-Child Transmission of HIV (PMTCT) visits have contributed to the delayed achievement of elimination of mother-to-child transmission of HIV. Missed visits promote attrition from prevention of mother-to-child transmission of HIV program and antiretroviral drug resistance. The purpose of the study was to determine the prevalence of missed PMTCT visits and its associated predictors. A descriptive cross sectional survey was carried out at a District Hospital in Goromonzi, Zimbabwe. Fifty-three women completed closed-ended questionnaires pertaining to PMTCT visits and exposure to PMTCT activities. A total of 24.5% missed at least one scheduled PMTCT visit. Statistically significant predictors of not missing a PMTCT visit were satisfaction with family support (β = −0.73, p = 0.029) and level of satisfaction with PMTCT services (β = −0.00076;p = 0.04). The number of days by which scheduled visits were missed were inversely correlated with visit number (β = −2.99, p = 0.04). Enhanced family support and quality improvement to improve patient satisfaction may reduce missed visits. Availing women with a more active role in PMTCT may also reduce the prevalence of missed visits.

Prevention of Maternal-to-Child Transmission of HIV: Knowledge, Attitude and Factors Influencing Active Participation among HIV-Positive Men in a Military Health Facility in Lagos, South Western Nigeria

Introduction: Traditionally, Prevention of Maternal-to-Child Transmission (PMTCT) of HIV involves women and excludes men despite their important roles. There is a need for more data on factors influencing male participation in PMTCT programs. Design: This was a cross-sectional, descriptive study of married HIV-positive men receiving care at the adult ART clinic, 68 Nigerian Army Reference Hospital Yaba. Data were collected from March 15 to April 30, 2018. Result: Out of the 366 respondents, 333 (91%) were aware that HIV can be transmitted from mother to child. However, only 43.2% correctly identified that it can be transmitted during pregnancy, while 30.2% stated during labour. Almost all of the respondents (96.4%) would also accept that their positive partners take antiretroviral treatment to protect her unborn baby, 86.9% would support non breastfeeding option after delivery, and 95.6% indicated readiness to buy formula milk for the baby. Similarly, majority believed that a pregnant woman can be tested for HIV without the permission of her partner (Mean = 1.47 ± 0.893), and that men should accompany their spouse to ANC/PMTCT clinics (Mean = 1.86 ± 0.921). Conclusion: This study revealed that despite low knowledge of PMTCT among men, there is a good level of attitude and involvement among them. We recommend further study to fully explore the impact of education on men’s participation.

Knowledge, Attitudes and Perceptions of Secondary School Teenagers towards HIV Transmission and Prevention in Rural and Urban Areas of Central Uganda

HIV/AIDS has remained a challenge in Uganda among adolescent despite the ABC strategy used globally to prevent HIV infection. The study assessed the knowledge, attitudes and perceptions of secondary school teenagers towards HIV transmission and prevention in rural and urban schools of central Uganda. A cross sectional study using self-administered questionnaires and structured interviews was used to collect data from adolescents in secondary schools in Kampala and Buikwe districts. Eight schools were randomly selected with 4 schools in each district. A total of 245 students from schools were recruited in the study with 120 and 125 students from urban Kampala and rural Buikwe district schools respectively. Data were analyzed using SPSS version 11. The results were expressed as percentages in a 2 × 2 tables. The mean age of the participants was 15.9 ± 2.5 years. Results showed that 95.1% participants had knowledge on HIV/AIDS in both urban and rural schools and 27.4% knew all the modes of HIV transmission. About 83.7% knew the ABC strategy for HIV prevention and 37.6% would talk about HIV/AIDS mainly with friends. For HIV cure, 62.0% of study participants reported non-cure and 24.9% were not sure. The remaining 13.1% of the study participants in both urban and rural schools reported that HIV can be cured. And the modes of curing HIV that were mentioned by participants included spiritual healing, transmitting it to others through sexual intercourse and that antiretroviral (ARVs) drugs can cure it as well as that it can be cured abroad. About 65.7% of participants reported recognition of one with HIV/ AIDS and by having red lips, being sickly;weight loss, skin rash and being very rich were mentioned. About 39.2% of the study participants mentioned that they cannot get infected with HIV and can’t contract HIV at all and 18.4% believed that chances of getting HIV infection were high. On perception and attitude on condoms and their use, participants reported that it is a sign of mistrust, reduces sexual pleasures and they are embarrassing to buy. Majority of the participants in both urban and rural schools had some knowledge on HIV/AIDS and the ABC strategy for HIV prevention. However, there was a knowledge gap on the various modes of HIV transmission and prevention. There was misconception of the participants on HIV/AIDS cure, condom use and on the chances of contracting HIV. About the source of HIV/AIDS information, majority of the participants were getting information on HIV/AIDS from friends of which some information was misleading. This false information could be the reason for the increased HIV prevalence reported among the adolescents in the schools. Generally, participants had some knowledge on HIV/AIDS though they had knowledge gap on HIV transmission and prevention.

Evaluation of the Implementation of the WHO’s 2010 Guide on Prevention of Mother To-Child Transmission (PMTCT) of HIV/Aids: Case of Two Hospitals in Yaoundé

Introduction: The prevalence of HIV infection amongst pregnant women in Cameroon is 5.6%. Mother-to-child transmission is a major expansion factor. In 2010, Cameroon adopted new strategies pegged to WHO guidelines. Objectives: The objective of this study was to evaluate the implementation of the new guidelines of prevention of mother to-child transmission (PMTCT) of HIV in the Yaoundé Central Hospital and the Yaoundé Teaching Hospital. Methodology: It was a cross sectional descriptive and prospective study over a period of 6 months in Yaoundé. It included all HIV-positive women, doing their antenatal care in the above cited hospitals, and having given their consent. The studied variables included socio demographic features, obstetrical history, the antenatal care, the initiation of anti retroviral (ARV) drugs, the ARV regimen, the number of years on ARV drugs, the mode of delivery and the mother and child outcome. The data was collected using a pre-tested questionnaire. They were obtained by interview of the seropositive pregnant women. Data were analysed using Epi info 3.5.3. Results: We performed 3104 antenatal consultations and 287 women were recruited in the study. The prevalence of HIV infection was 9.24%. The mean age of women was 28.77 (SD: 5.13) years. The women were aged between 20 and 29 years in 51.20%. Amongst the 156 women who knew their status before pregnancy, 109 (70.50%) had their first ANC in the first trimester. All were managed according to the 2010 WHO recommendations on PMTCT of HIV. Amongst the women unaware of their status, 25.20% had their booking ANC in the first trimester, 25.14% started ARVs at 14 weeks, 69.46% at 28 weeks. We had 125 live births, 84.8% by vaginal route, neonatal prophylaxis in all babies was effective. Conclusion: PMTCT of HIV is available and guidelines are well applied in Yaoundé. Late treatment initiation still remains a problem to optimize care.

Beliefs and practices of young women on utilization of prevention of mother to child transmission of HIV services in Malawi

This study explored beliefs and actual practices of young women on utilization of Prevention of Mother to Child Transmission (PMTCT) of HIV services in Balaka district of Southern Malawi. The study design wascross sectional which utilized qualitative data collection and analysis methods. In-depth interviews were conducted on 12 young mothers of 15 to 24 years old. The respondents were drawn from 6 health centres in the district during their visits to either the under-five clinic, HIV and AIDS support groups or HIV follow up clinics. Data were analyzed using thematic analysis approach. Overall the respondents had positive beliefs on utilization of PMTCT services. They believed that adherence to PMTCT guidelines such as condom use, taking of Nevirapine (NVP) and exclusive breastfeeding protected the baby from contracting the virus. Nevertheless, all respondents believed that HIV testing was mandatory and that early weaning caused malnutrition and death of babies. Actual practice was very low. Very few young mothers breastfed exclusively, weaned their babies abruptly and took NVP as recommended. Not all positive beliefs translated into positive behavior. Lack of male support, inability of the midwives to provide comprehensive care to HIV infected mothers and their infants, and fear of stigma and discrimination were other factors that hindered utilization of PMTCT services. Culture was also a major barrier because traditionally babies are expected to be breastfed and supplements are fed to babies too. Therefore, there is a need to mobilize communities on PMTCT of HIV. Education programmes in HIV should emphasize behavior change interventions and should focus on both men and women and significant others. There is also need to intensify monitoring and evaluation of health workers’ activities to ensure that beliefs translate into positive behavior.

Examine a dynamic of mother-to-child transmission of HIV in the population-based surveys

The main source of HIV infection in young children is of their mothers, during pregnancy, labor and delivery, or by breastfeeding. The rate of HIV transmission from infected mothers to their newborn children varies from 15% to 40% with one-thirds of these infections was through breastfeeding. This paper examines cross-sectional population-based survey data of HIV test results among mothers and their children in Uganda, Swaziland to estimates of mother-to- child transmission (MTCT) rate of HIV infection. The prevalence of HIV among women aged 15 - 49 who gave birth in the past 5 years in Uganda is 7.3%, and in Swaziland is 37.9%. The HIV prevalence of children who mothers were HIV positive were very similar: 10.3% in Uganda and 11.5% in Swaziland. This association represents the crude rate of MTCT in these two countries at the time of the survey. Presence of HIV antibody in early age (0 - 11 months) is due to both true infection and passive antibody from mothers. The seroconversion dropped nearly half in the second year of age which was likely that many of these children died before reaching the age of 12 - 23 months and passive antibody were gradually cleared at this point. This analysis demonstrated that cross-sectional data can be used to estimate indirectly the magnitude and dynamic of MTCT.

Evaluating the Knowledge of HIV Transmission and Prevention of Mother to Child Transmission (PMTCT) of HIV among HIV-Positive Mothers Accessing Care in Military Hospital in Lagos, Nigeria

Introduction: The prevention of mother-to-child transmission (PMTCT) plays a major role in limiting the number of children being infected by HIV. There is dearth of studies that explored the knowledge of HIV transmission and PMTCT among women living with HIV. Methods: This was a cross-sectional, descriptive study of HIV-positive mothers receiving medical care at the adult antiretroviral therapy (ART) clinic, 68 Nigeria Army Reference Hospital Yaba. A pre-tested structured questionnaire was used to collect information from the subjects concerning their socio-demographic, knowledge of HIV transmission and mother-to-child transmission of HIV and preventive measures. SPSS v23 was used for data analysis. Results: Out of the 374 participants, 282 (75.4%) were aware that HIV can be transmitted to an unborn baby from the positive mother. Of these, 240 (85.1%) were well-informed that increase mother’s viral load can increase the chances of mother-to-child transmission. 268 (95%) understood that giving of antiretroviral drugs during and after pregnancy can lower transmission risk, while 254 (90.1%) saw the use of breast milk substitutes as another prevention strategy. There was statistically significant association between the respondents’ knowledge of PMTCT and their husbands’/partners’ awareness of their HIV status. Conclusion: In conclusion, our study demonstrated a good knowledge of HIV transmission, MTCT and PMTCT among women who were receiving ART in our centre. Disclosure is a significant factor found to be associated with PMTCT knowledge. More studies can also explore if the observations in our study with women living with HIV will be comparable in similar population in different settings.

A survey of awareness and knowledge of mother-to-child transmission of HIV in pregnant women attending Olabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria

Objective: To determine the knowledge and awareness of Human Immunodeficiency Virus (HIV)/Acquired Immunodeficiency Syndrome (AIDS) and mother-to-child transmission (MTCT) among women attending the antenatal clinic. Methods and Subjects: This was primarily a descriptive cross-sectional study carried out at the antenatal clinic of Olabisi Onabanjo University Teaching Hospital (OOUTH), Sagamu, Nigeria from July 1st, 2010 to October 31st, 2010. Results: The age range of the respondents was 18 - 41 years, (mean 29 ± 5 years). One hundred and forty-nine (92.5%) were married. All the respondents interviewed were aware of HIV/AIDS and 93 (57.8%) had been aware of the disease for ≥5 years. The main sources of information were television 93 (57.8%), radio 77 (47.8%), health workers 53 (32.9%), friends, relatives and neighbors 41 (25.5%) and posters 34 (21.1%). Majority of the respondents identified sexual intercourse as a route of transmission of HIV. Sharing of sharp objects and blood transfusion were identified as routes of transmission by 99 (61.5%) and 82 (50.9%) respectively. One hundred and sixteen (72%) of the respondents knew an apparently healthy person could be living with HIV. Majority of the respondents 125 (77.6%) were aware that HIV can coexist with pregnancy and 120 (74.5%) were aware of MTCT of HIV. Vaginal delivery and breastfeeding were identified as routes of HIV transmission by 44 (27.3%) and 53 (32.9%) of respondents respectively. Delivery by caesarean section was identified as a method of prevention of MTCT by 25 (15.5%) respondents while as many as 48 (29.8%) respondents did not know any method of prevention of MTCT of HIV. Conclusion: This study demonstrates a low level of awareness of methods of prevention of MTCT of HIV among pregnant women booking for antenatal care in our center. Thus, there is the need for adequate counseling about HIV/AIDS and specific aspects of prevention of mother-to-child transmission in our antenatal clinics.

Patient-Reported Factors Facilitating Participation in Prevention of Mother to Child Transmission of HIV Programs in Kara, Togo, West Africa

Background: Despite efforts to expand prevention of mother-to-child transmission (PMTCT) of HIV in resource-limited settings, only 53% of women in sub-Saharan Africa receive adequate PMTCT services. Understanding factors that enable successful program completion are crucial to improving adherence rates to PMTCT programs in these settings. Using a positive deviance approach, we explored patient and provider’s perspectives on factors enabling women to successfully access and adhere to PMTCT services to identify areas of program improvement and further reduce HIV transmission. Methods: Semi-structured interviews were conducted with 11 health care workers (HCWs) at two health centers in Kara, Togo and 34 women who had successfully completed the PMTCT program at those facilities. Women were identified using purposive sampling and content theme analysis was used to analyze the data. Results: Knowledge and belief in the potential to give birth to an HIV-negative child, supported by facilitating factors on the individual and community levels, was the cornerstone to women’s PMTCT program success. Effective program education and peer-to-peer interactions fostered the participants’ knowledge and belief in PMTCT, with the resulting internal motivation driving continued participation and adherence. The welcoming environment, availability of peer support groups and financial assistance from the health facility, further facilitated success, with women using this facility-based community to seek advice and support from HCWs and peers. Financial, physical, and emotional support from relatives was also important in ensuring unhindered access. Finally, the faith-based communities’ acceptance and support for HIV-positive women further encouraged participants to adhere to the program. Conclusion: Understanding and believing in the ability to have an HIV-negative baby was the most important facilitator for PMTCT program adherence. This led to internal motivation that was continually reinforced through facility and community supportive environments focused on addressing barriers. Efforts to improve PMTCT success should focus on all of these factors through a patient-centered approach.

Mother-to-Child Transmission of HIV/AIDS during Pregnancy and Delivery and Associated Factors in the Region of Couffo in Benin

Evaluation of the effectiveness of the mother-to-child HIV Prevention Program, in Benin in 2016 reported a national rate of 6.7%. The Region of Couffo, within 12 Regions (departments) in the country, had the highest rate of transmission, which was 16.1%. The study aimed to determine transmission rate during pregnancy and delivery as well as the factors associated with it. This is a retrospective and analytical study based on a sample of seventy (70) babies born to HIV-infected mothers in 2016 in Couffo. Key findings showed, there is a perinatal transmission of five percent (5%) and the factors associated with this transmission are: delay in carrying out first antenatal visits at the health facility, low frequency of visits performed versus number requested and appropriate time, poor health condition of mothers during pregnancy, absence or late start of antiretroviral care and treatment during pregnancy, irregular intake of intermittent presumptive treatment at sulfadoxine-pyrimethamine to prevent malaria, a short antiretroviral therapy (less than three months) for mothers before delivery and the default in cleaning mother’s genital tract with betadine after the woman’s water broke.

Strategies to Prevent Mother-to-child Transmission of Hepatitis B Virus

Mother-to-child transmission(MTCT)of hepatitis B virus(HBV)is the primary cause of chronic HBV infection worldwide.MTCT prevention and antiviral treatment of infected individuals could eliminate this public health burden.Antiviral treatment of hepatitis B surface antigen(HBsAg)-positive pregnant women and immunoprophylaxis with HBV vaccine and hepatitis B immune globulin are the most effective strategies to interfere with MTCT of HBV.However,for worldwide application of those strategies,feasibility,availability,cost,safety,and effectiveness should be considered.Cesarean section and breastfeeding avoidance in hepatitis B e antigenpositive mothers with a high viral load and without antiviral therapy during pregnancy could be an option,but more supporting evidence is needed.HBsAg screening of all pregnant women is recommended when initiating antiviral therapy and immunoprophylaxis for MTCT prevention,except in areas with limited resources.Timely HBV vaccination series administered soon after birth might be the mainstay of prevention.This review aimed to provide a concise update on the effectiveness of available strategies to prevent MTCT of HBV.

感染HIV的孕产妇预防艾滋病母婴传播服务利用及影响因素分析

目的了解感染艾滋病病毒(HIV)的孕产妇对预防艾滋病母婴传播(PMTCT)服务的利用状况,分析影响因素。方法在河南、广西、新疆、云南省(自治区)的15个县/市/区,对2004年1月至2006年6月检测发现的感染HIV的孕产妇346人,通过问卷调查方式,结合相关医疗记录在孕期、产时和产后分阶段完成调查。调查内容包括人口学特征、相关行为、感染途径、PMTCT服务的利用情况等。结果346名感染HIV的孕产妇中94.80%接受过产前检查,95.95%住院分娩,其希望住院分娩的原因是医院医疗技术水平高(58.28%),服务质量好(47.27%),收费低(33.33%),能够提供PMTCT服务(33.03%),保密性好(26.97%),交通方便(23.33%)等。87.57%的母婴应用抗艾滋病病毒药物,规范应用抗病毒药物者占46.82%。感染HIV的孕产妇所娩婴儿中,89.02%采取人工喂养方式,满18月龄时进行HIV检测者占93.75%。检测后咨询包含PMTCT内容、民族和文化程度对规范应用抗病毒药物有影响作用(P<0.05)。结论感染HIV的孕产妇对PMTCT服务的需求特殊,PMTCT服务利用尚不足,检测后咨询及咨询内容影响抗病毒药物的规范应用。建议加强HIV/ADIS高发地区基础妇幼保健服务,提高妊娠妇女早期和孕中期HIV抗体检测水平,重视感染HIV孕产妇抗病毒药物的规范应用和安全助产,为感染HIV的孕产妇及所娩婴儿提供个性化的、综合的PMTCT服务。

HIV母婴传播阻断综合措施与效果评价

目的分析妊娠合并人类免疫缺陷病毒(HIV)感染孕产妇实行综合性母婴阻断措施的效果。方法回顾性分析北京地坛医院2003年至2017年81例合并HIV感染的孕产妇实行综合性阻断措施后,新生儿感染HIV的情况。结果经过艾滋病母婴传播阻断综合干预后,81例孕产妇中有10例在知情同意后选择终止妊娠,纳入母婴阻断服药的人数为71例。71例合并HIV感染的孕产妇中,流产7例次,生产65例次,65例新生儿均进行了新生儿药物阻断,阻断成功率为100.0%。结论对HIV感染的孕产妇进行综合性母婴传播阻断措施,可以很大程度上降低HIV的母婴传播率,控制新生儿艾滋病流行。

HIV母婴传播影响因素及我国预防HIV母婴传播对策

预防艾滋病母婴传播是艾滋病防制的重要组成部分。文章分析了HIV母婴传播影响因素,总结了我国预防HIV母婴传播对策与措施,并探讨了我国预防HIV母婴传播应注意的几个问题。

HIV母婴阻断的研究进展

人类免疫缺陷病毒(H IV)的广泛流行已成为全球最为瞩目的公共卫生问题和社会问题.据估计全球每年大约有220万妇女和60万儿童感染H IV,其中90%的儿童是通过母婴传播途径感染的,所以进行H IV母婴阻断对控制H IV的流行具有非常重要的意义.目前主要的母婴阻断方式包括抗逆转录病毒治疗、剖宫产及人工喂养等.

系统电话教育对新疆边远地区维吾尔族HIV母婴传播的预防效果

目的探讨系统电话教育对新疆边远地区维吾尔族HIV阳性孕妇对HIV母婴传播预防措施知晓情况的影响,观察系统电话教育对HIV母婴传播的预防效果。方法选择2008年1月—2012年12月在新疆医科大学第一附属医院就诊的新疆边远地区（远离最近二级医院300 km以上）维吾尔族HIV阳性非妊娠患者80例。应用随机数余数分组法分为系统电话教育干预组（n=40）及未干预组（n=40）。两组均半年进行1次随访,干预组在此基础上每月进行1次系统电话教育。干预时间为计划妊娠前3个月-产后6个月。比较干预后两组患者HIV母婴传播预防知晓评分、抗病毒药物服药依从性、剖宫产、婴儿替代喂养行为及婴儿HIV感染率的差异。结果干预后两组HIV母婴传播预防知晓评分间差异有统计学意义〔（5.1±1.4）分与（3.5±1.8）分,t=5.50,P〈0.05〕;干预后干预组与未干预组患者抗病毒药物服药依从性（87.5%与60.0%）、剖宫产率（95.0%与80.0%）、婴儿替代喂养率（92.5%与72.5%）及婴儿定期检测率（97.5%与75.0%）间差异均有统计学意义（P〈0.05）。干预组婴儿HIV感染率（2.6%）与未干预组（20.0%）间差异有统计学意义（χ2=3.99,P〈0.05）。结论系统电话教育能显著提高新疆边远地区维吾尔族HIV抗体阳性孕妇对HIV母婴传播预防知识的知晓程度,降低HIV母婴传播率。
