Children and HIV/AIDS: from research to policy and action in resource-limited settings

Clinical Characteristics of Children with HIV Initiated on Antiretroviral Treatment at HIV Clinics in Bloemfontein, South Africa

BACKGROUND AND OBJECTIVE

Over the past 15 years, there have been three major updates to the South African national guidelines for the management of human immunodeficiency virus (HIV) in children. The purpose of this study is to describe the clinical characteristics of children who were initiated on antiretroviral therapy (ART) in Bloemfontein, South Africa, following these national treatment guidelines.

METHODS

Clinical information during initiation of ART in children aged 0-13 years was obtained from five HIV clinics in Bloemfontein from 2004 to 2019 as part of the establishment of an antiretroviral (ARV) pediatric registry at the University of the Free State. Data were analyzed for patient demographics, clinical presentation (World Health Organization (WHO) HIV-staging, growth rate and comorbid conditions), types of investigations done, and medicines prescribed.

RESULTS

The number of children initiated on ART increased from 168 in the period 2004-2009 to 349 (107.8%) in 2010-2014, and then dropped to 162 in the period 2015-2019. The increase in 2010-2014 was mainly in the <2 years age group by 54.8%, and in the 5 to 10 years age group by 344.4%. In the same period, the number of children with severe illness (WHO HIV-stage 4) decreased by 20.7%, while those with mild to moderate illness (WHO HIV-stage 2 and 3) increased by 17.3%. HIV infection was more severe in children under two years as more patients in this age group presented with WHO HIV-stages 3 and 4, severe underweight (below 3^rd percentile), severely suppressed CD4 count (< 25%), and a high viral load (> 1000 copies/ml). There was increased use of ABC/3TC/LPVr in the < 3-year age group and ABC/3TC/EFV in the > 3-year age group. There was reduced use of the stavudine and other regimens.

CONCLUSION AND GLOBAL HEALTH IMPLICATIONS

More children were started on ART and safer ARV drugs. Children under 2 years were the most debilitated by HIV, and there was an increase in HIV prevalence among children > 5 years. New strategies for the prevention and management of HIV among children in these two age groups are needed.

Low rate of early vertical transmission of HIV supports the feasibility of effective implementation of the national PMTCT guidelines in routine practice of referral hospitals in Cameroon

Background: Vertical (VT) transmission of HIV remains a public health concern in sub-Saharan Africa. Objective: To investigate the VT rate and factors associated with transmission in routine practice in three referral hospitals in Cameroon. Methods: All HIV-infected mothers who delivered in maternity wards or sought paediatric services during the first postnatal week from November 2007 to October 2010 were invited to participate in the ANRS-Pediacam cohort. Their infants were followed at 6, 10 and 14 weeks of life and HIV status was determined from the 6th week of life using real-time PCR. For those who were breastfed and negative at the first PCR, a second test was performed 6 weeks after breast-feeding was stopped. Logistic regression was performed to identify the independent risk factors of VT. Results: Overall, 2053 HIV-exposed infants were enrolled. Of these, 1827 were tested for HIV including 1777 before the age of 3 months, and 59 were HIV-infected, resulting in an overall early VT rate of 3.3% (CI 2.5-4.3). The VT rate was significantly associated with the type of maternal exposure to ART (0.5%, 2/439, p<0.001, CI 0.0-1.6) in mothers who commenced HAART before pregnancy, 1.9% (6/321, CI 0.7-4.0) in mothers who commenced HAART during pregnancy, 4.1% (34/837, CI 2.8-5.6) in those on short-course ART and 11.1% (17/153, CI 6.6-17.2) in mothers not receiving ART. On multivariate analysis, the type of exposure to ART remained significantly associated with being small for gestational age (aOR 5.0, CI 2.4-10.3, p < 0.001) and female gender (aOR 2.1, CI 1.2-3.8, p = 0.01). Conclusion: The successfully low rate of VT transmission of HIV in mothers who commenced HAART in early pregnancy strongly supports the need to improve access to diagnosis and early treatment of all women of childbearing age with HIV through the national PMTCT programme.

Implementation and Operational Research: Effects of Antenatal Care and HIV Treatment Integration on Elements of the PMTCT Cascade: Results From the SHAIP Cluster-Randomized Controlled Trial in Kenya

BACKGROUND

Integrating antenatal care (ANC) and HIV care may improve uptake and retention in services along the prevention of mother-to-child transmission (PMTCT) cascade. This study aimed to determine whether integration of HIV services into ANC settings improves PMTCT service utilization outcomes.

METHODS

ANC clinics in rural Kenya were randomized to integrated (6 clinics, 569 women) or nonintegrated (6 clinics, 603 women) services. Intervention clinics provided all HIV services, including highly active antiretroviral therapy (HAART), whereas control clinics provided PMTCT services but referred women to HIV care clinics within the same facility. PMTCT utilization outcomes among HIV-infected women (maternal HIV care enrollment, HAART initiation, and 3-month infant HIV testing uptake) were compared using generalized estimating equations and Cox regression.

RESULTS

HIV care enrollment was higher in intervention compared with control clinics [69% versus 36%; odds ratio = 3.94, 95% confidence interval (CI): 1.14 to 13.63]. Median time to enrollment was significantly shorter among intervention arm women (0 versus 8 days, hazard ratio = 2.20, 95% CI: 1.62 to 3.01). Eligible women in the intervention arm were more likely to initiate HAART (40% versus 17%; odds ratio = 3.22, 95% CI: 1.81 to 5.72). Infant testing was more common in the intervention arm (25% versus 18%), however, not statistically different. No significant differences were detected in postnatal service uptake or maternal retention.

CONCLUSIONS

Service integration increased maternal HIV care enrollment and HAART uptake. However, PMTCT utilization outcomes were still suboptimal, and postnatal service utilization remained poor in both study arms. Further improvements in the PMTCT cascade will require additional research and interventions.

What can volunteer co-providers contribute to health systems? The role of people living with HIV in the Thai paediatric HIV programme

In Thailand people living with HIV (PLHIV) have played a major role in shaping policy and practice. They have acted as volunteer co-providers, although their potential in terms of paediatric service provision has seldom been explored from a health systems perspective. We describe the Thai paediatric HIV care system and use both demand- and supply-side perspectives to explore the impact, opportunities and challenges of PLHIV acting as volunteer co-providers. We employed qualitative methods to assess experiences and perceptions and triangulate stakeholder perspectives. Data were collected in Khon Kaen province, in the poorest Northeastern region of Thailand: three focus group discussions and two workshops (total participants n = 31) with co-providers and hospital staff; interviews with ART service-users (n = 35). Nationally, key informant interviews were conducted with policy actors (n = 20). Volunteer co-providers were found to be ideally placed to broker the link between clinic and communities for HIV infected children and played an important part in the vital psychosocial support component of HIV care. As co-providers they were recognized as having multiple roles linking and delivering services in clinics and communities. Clear emerging needs include strengthened coordination and training as well as strategies to support funding. Using motivated volunteers with a shared HIV status as co-providers for specific clinical services can contribute to strengthening health systems in Asia; they are critical players in delivering care (supply side) and being responsive to service-users needs (demand side). Co-providers blur the boundaries between these two spheres. Sustaining and optimising co-providers' contribution to health systems strengthening requires a health systems approach. Our findings help to guide policy makers and service providers on how to balance clinical priorities with psycho-social responsiveness and on how best to integrate the views and experience of volunteers into a holistic model of care.

Morbidity and health care resource utilization in HIV-infected children after antiretroviral therapy initiation in Côte d'Ivoire, 2004-2009

BACKGROUND

We describe severe morbidity and health care resource utilization (HCRU) among HIV-infected children on antiretroviral therapy (ART) in Abidjan, Côte d'Ivoire.

METHODS

All HIV-infected children enrolled in an HIV-care program (2004-2009) were eligible for ART initiation until database closeout, death, ART interruption, or loss to follow-up. We calculated incidence rates (IRs) of density per 100 child-years (CYs) for severe morbidity, HCRU (outpatient care and inpatient care), and associated factors using frailty models with a Weibull distribution.

RESULTS

Of 332 children with a median age of 5.7 years and median follow-up of 2.5 years, 65.4% were severely immunodeficient by World Health Organization (WHO) criteria, and all received cotrimoxazole prophylaxis. We recorded 464 clinical events in 228 children; the overall IR was 57.6/100 CYs [95% confidence interval (CI): 52.1 to 62.5]. Severe morbidity was more frequent in children on protease inhibitor (PI)-based ART compared to those on other regimens [adjusted hazards ratio (aHR): 1.83; 95% CI: 1.35 to 2.47] and to those moderately/severely immunodeficient compared to those not (aHR: 1.57; 95% CI: 1.13 to 2.18 and aHR: 2.53; 95% CI: 1.81 to 3.55, respectively). Of the 464 events, 371 (80%) led to outpatient care (IR: 45.6/100 CYs) and 164 (35%) to inpatient care (IR: 20.2/100 CYs). In adjusted analyses, outpatient care was significantly less frequent in children older than 10 years compared with children younger than 2 years (aHR: 0.49; 95% CI: 0.31 to 0.78) and in those living furthest from clinics compared with those living closest (aHR: 0.65; 95% CI: 0.47 to 0.90). Both inpatient and outpatient HCRU were negatively associated with cotrimoxazole prophylaxis.

CONCLUSIONS

Despite ART, HIV-infected children still require substantial utilization of health care services.

Resource Utilization and Costs of Care prior to ART Initiation for Pediatric Patients in Zambia

Objective. We estimated time to initiation, outpatient resource use, and costs of outpatient care during the 6 months prior to ART initiation for HIV-infected pediatric patients in Zambia. Methods. We enrolled 1,102 children who initiated ART at <15 years of age between 2006 and 2011 at 5 study sites. Of these, 832 initiated ART ≤6 months after first presenting to care at the study sites. Data on time in care and resources utilized during the 6 months prior to ART initiation were extracted from patient medical records. Costs were estimated from the provider's perspective and are reported in 2011 USD. Results. For the patients who initiated ART ≤6 months after presenting to care, median age at presentation to care was 3.9 years; median CD4 percentage was 13%. Median time to ART initiation was 26 days. Patients made, on average, 2.38 clinic visits prior to ART initiation and received 0.81 CD4 tests, 0.74 full blood count tests, and 0.49 blood chemistry tests. The mean cost of pre-ART care was $20 per patient. Conclusions. Zambian pediatric patients initiating ART ≤6 months after presenting to care do so quickly, utilize fewer resources than mandated by national guidelines, and accrue low costs.

Married Men Perceptions and Barriers to Participation in the Prevention of Mother-to-Child HIV Transmission Care in Osogbo, Nigeria

Men's role in HIV prevention is pivotal to changing the course of the epidemic. Men's barriers toward participation in Prevention of Mother-to-Child Transmission (PMTCT) have not been adequately documented. This study is therefore designed to determine men's level of awareness and barriers to their participation in PMTCT programmes in Osogbo, Nigeria. This study was a descriptive qualitative one that utilized Focus Group Discussion (FGD). One-hundred and sixty married men were selected by convenience sampling and interviewed. Data collected were analysed using content analysis technique. Demographic data were analysed using SPSS 15.0 software to generate frequency tables. Participants mean age was 31.9 ± 5.9 years. Many of the participants had heard about PMTCT and the majority agreed that it is good to accompany their wife to Antenatal Care (ANC) but only few had ever done so. Societal norms and cultural barriers were the leading identified barriers for male involvement in PMTCT programmes. The majority of the participant perceived it was a good idea to accompany their wife to antenatal care but putting this into practice was a problem due to societal norms and cultural barriers. Community sensitization programmes such as health education aimed at breaking cultural barriers should be instituted by government and nongovernmental agencies.

Scaling up paediatric HIV care with an integrated, family-centred approach: an observational case study from Uganda

Family-centred HIV care models have emerged as an approach to better target children and their caregivers for HIV testing and care, and further provide integrated health services for the family unit's range of care needs. While there is significant international interest in family-centred approaches, there is a dearth of research on operational experiences in implementation and scale-up. Our retrospective case study examined best practices and enabling factors during scale-up of family-centred care in ten health facilities and ten community clinics supported by a non-governmental organization, Mildmay, in Central Uganda. Methods included key informant interviews with programme management and families, and a desk review of hospital management information systems (HMIS) uptake data. In the 84 months following the scale-up of the family-centred approach in HIV care, Mildmay experienced a 50-fold increase of family units registered in HIV care, a 40-fold increase of children enrolled in HIV care, and nearly universal coverage of paediatric cotrimoxazole prophylaxis. The Mildmay experience emphasizes the importance of streamlining care to maximize paediatric capture. This includes integrated service provision, incentivizing care-seeking as a family, creating child-friendly service environments, and minimizing missed paediatric testing opportunities by institutionalizing early infant diagnosis and provider-initiated testing and counselling. Task-shifting towards nurse-led clinics with community outreach support enabled rapid scale-up, as did an active management structure that allowed for real-time review and corrective action. The Mildmay experience suggests that family-centred approaches are operationally feasible, produce strong coverage outcomes, and can be well-managed during rapid scale-up.

Antiretroviral therapy, pregnancy, and birth defects: a discussion on the updated data

An increasing number of HIV-infected women of childbearing age are initiating antiretroviral therapy (ART) worldwide. This review aims to discuss updated data of the eligible ART regimens and their role in inducing birth defects in utero. Zidovudine and lamivudine plus a non-nucleoside reverse-transcriptase inhibitor or protease inhibitor (PI) is the first-line regimen applied. The role of zidovudine exposition monotherapy or associated with other ART in inducing birth defects remains inconclusive. The main organ systems involved are genitourinary and cardiovascular. For HIV-infected pregnant women, World Health Organization (WHO) guidelines up to 2010 recommend the same group of drugs that are prescribed to nonpregnant women. The exception is efavirenz, which has been associated with an increase in the risk of teratogenicity. Increased rates of birth defects were found in large cohorts and computational studies conducted recently in infants exposed to efavirenz-containing regimens. The combination of zidovudine and lamivudine and lopinavir/ritonavir is one of the most used ART regimens for prevention of mother-to-child-transmission. Conflicting data about the role of PI exposure in utero and birth defects have been reported. However, a reduced number of studies evaluating the role of PI in inducing birth defects in women are available. An association between prematurity and PI exposure in pregnancy was extensively described. Some questions arise due to the tendency of initiating ART early in the life of HIV-infected individuals or those at risk of infection. Longtime exposure to different ART regimens and the potential effect of birth-defect induction in pregnancy are not completely understood. Developing regions harbor the highest numbers of women of reproductive age exposed to ART. Most of the largest and expressive data come from developed countries, and could not be sufficiently representative of pregnant women living in developing countries.

Health care resource utilization in untreated HIV-infected children in a pediatric programme, Abidjan, Côte d'Ivoire, 2004-2009

BACKGROUND

We describe health care resource utilization among HIV-1-infected children who have not yet undergone antiretroviral treatment (ART) in Abidjan, Côte d'Ivoire.

METHODS

HIV-infected children enrolled prospectively in an HIV care programme in 2 health facilities in Abidjan (2004-2009) were followed up from date of inclusion until database closeout, death, ART initiation, or loss to follow-up (no clinical contact for more than 6 months). Incidences of health care resource utilization (outpatient care, inpatient day care, and hospitalization) were described according to severe morbidity and mixed effect log linear models were computed to identify associated factors.

RESULTS

Overall, 405 children were included, entering care at a median age of 4.5 years, 66.9% were receiving cotrimoxazole prophylaxis, and 27.7% met 2006 WHO criteria for immunodeficiency by age. The median follow-up time was 11.6 months (interquartile range: 1.4; 30.7). Overall, 371 clinical events occurred in 162 children yielding to an incidence rate (IR) of 60.9/100 child-years (CY) [95% confidence interval (CI): 55.1 to 67.2]: 57% of clinical events led to outpatient care (IR: 33/100 CY), 38% to inpatient day care (IR: 22/100 CY), and 10% to hospitalization (IR: 5.9/100 CY). Further medical examinations were made allowing confirmed diagnoses in 40% of those (IR: 22.4/100 CY). Outpatient care was less common among immunodeficient children than those not (relative risk [RR] = 0.32, 95% CI: 0.18 to 0.56), in those whose main caregivers are both parents compared with those who are primarily cared for by their mother only (RR = 0.34, 95% CI: 0.15 to 0.77).

CONCLUSION

Untreated HIV-infected children require substantial inpatient and outpatient care in a context where ART is scaling up but still not available to all.

Male involvement in prevention programs of mother to child transmission of HIV: a systematic review to identify barriers and facilitators

BACKGROUND

Many reports point to the beneficial effect of male partner involvement in programs for the prevention of mother-to-child-transmission (PMTCT) of HIV in curbing pediatric HIV infections. This paper summarizes the barriers and facilitators of male involvement in prevention programs of mother-to-child-transmission of HIV.

METHODS

We searched PubMed, EMBASE, CINAHL and the Cochrane Central Register of Controlled Trials (CENTRAL) for studies published in English from 1998 to March 2012. We included studies conducted in a context of antenatal care or PMTCT of HIV reporting male actions that affected female uptake of PMTCT services. We did not target any specific interventions for this review.

RESULTS

We identified 24 studies from peer-reviewed journals; 21 from sub-Saharan Africa, 2 from Asia and 1 from Europe. Barriers to male PMTCT involvement were mainly at the level of the society, the health system and the individual. The most pertinent was the societal perception of antenatal care and PMTCT as a woman's activity, and it was unacceptable for men to be involved. Health system factors such as long waiting times at the antenatal care clinic and the male unfriendliness of PMTCT services were also identified. The lack of communication within the couple, the reluctance of men to learn their HIV status, the misconception by men that their spouse's HIV status was a proxy of theirs, and the unwillingness of women to get their partners involved due to fear of domestic violence, stigmatization or divorce were among the individual factors. Actions shown to facilitate male PMTCT involvement were either health system actions or factors directly tied to the individuals. Inviting men to the hospital for voluntary counseling and HIV testing and offering of PMTCT services to men at sites other than antenatal care were key health system facilitators. Prior knowledge of HIV and prior male HIV testing facilitated their involvement. Financial dependence of women was key to facilitating spousal involvement.

CONCLUSIONS

There is need for health system amendments and context-specific adaptations of public policy on PMTCT services to break down the barriers to and facilitate male PMTCT involvement.

TRIAL REGISTRATION

The protocol for this review was registered with the International prospective register of systematic reviews (PROSPERO) record CRD42011001703.

HIV-1-mother-to-child transmission and associated characteristics in a public maternity unit in Presidente Prudente, Brazil

In children, vertical transmission is the main form of HIV infection. Our aim was to determine the prevalence of HIV-1 vertical transmission in mother-infant pairs in a public maternity ward in Presidente Prudente, SP. Additionally; we sought to identify characteristics associated with this form of transmission. The files of 86 HIV-1-infected mothers and their newborns referred to a Public Hospital from March 2002 to March 2007 were analyzed. The HIV-1-RNA viral load of the newborns was determined by bDNA. The HIV-1 vertical-transmission rate was 4.6%. Children that were born in the pre-term period and breastfed were at a higher risk of HIV-1 infection (p = 0.005 and p = 0.017 respectively) than children born at term and not breastfed. Prophylactic therapy with zidovudine after birth for newborns was associated with a lower risk of infection (p = 0.003). The number of newborns weighing < 2,500 g was significantly higher for infected children (p = 0.008) than for non-infected newborns. About 22.9% of mothers did not know the HIV-1 status of their newborns eight months after delivery. The study suggests that it is necessary to increase the identification of HIV-1 infection in pregnant women and their newborns as well as to offer and explain the benefits of ARV prophylaxis.

Institutionalizing provider-initiated HIV testing and counselling for children: an observational case study from Zambia

Background

Provider-initiated testing and counselling (PITC) is a priority strategy for increasing access for HIV-exposed children to prevention measures, and infected children to treatment and care interventions. This article examines efforts to scale-up paediatric PITC at a second-level hospital located in Zambia’s Southern Province, and serving a catchment area of 1.2 million people.

Methods and Principal Findings

Our retrospective case study examined best practices and enabling factors for rapid institutionalization of PITC in Livingstone General Hospital. Methods included clinical observations, key informant interviews with programme management, and a desk review of hospital management information systems (HMIS) uptake data following the introduction of PITC. After PITC roll-out, the hospital experienced considerably higher testing uptake. In a 36-month period following PITC institutionalization, of total inpatient children eligible for PITC (n = 5074), 98.5% of children were counselled, and 98.2% were tested. Of children tested (n = 4983), 15.5% were determined HIV-infected; 77.6% of these results were determined by DNA polymerase chain reaction (PCR) testing in children under the age of 18 months. Of children identified as HIV-infected in the hospital’s inpatient and outpatient departments (n = 1342), 99.3% were enrolled in HIV care, including initiation on co-trimoxazole prophylaxis. A number of good operational practices and enabling factors in the Livingstone General Hospital experience can inform rapid PITC institutionalization for inpatient and outpatient children. These include the placement of full-time nurse counsellors at key areas of paediatric intake, who interface with patients immediately and conduct testing and counselling. They are reinforced through task-shifting to peer counsellors in the wards. Nurse counsellor capacity to draw specimen for DNA PCR for children under 18 months has significantly enhanced early infant diagnosis. The hospital’s bolstered antiretroviral supply chain, package of on-site HIV services, and follow-up care for children and families improved the continuum of service uptake.

Conclusions and Significance

The clinical impact and operational experience emphasizes that institutional PITC is a feasible strategy for increasing access to paediatric HIV care, particularly in generalized epidemic settings.

A Paradigm Shift in the Epidemiology of HIV in Pregnancy at ICTC of a Medical College

OBJECTIVES

To study the present status and effect of paradigm shift in the epidemiology of HIV amongst pregnant women in urban set up.

AIMS

The purpose of the study is to evaluate the paradigm shift in overall screening and management strategy of HIV in antenatal women for last four and half years in an urban medical college.

METHODS

The study was conducted from 1st January 2004 to 30th June 2008 and all registered and unregistered pregnant women who attended ICTC clinic and also for emergency admission (unregistered) were counseled and blood samples were tested as per NACO guidelines with cafeteria choice of opt in and opt out strategy. Reactive women in antenatal period were counseled and discussed about anti-retroviral therapy (ART) and universal treatment regime. Seroprevalent women were counseled about their spouse, personal habits and demographic status. Marked improvement was seen in the use of contraceptive and drug abuse. During labor mother and baby were given nevirapine as per NACO guidelines.

RESULTS

The seroprevalence of HIV reactive women in our Centre was 0.23, 0.19, 0.14 and 0.12% in the year 2004, 2005, 2006, 2007 and zero prevalence in 2008 till date. Spouse positivity was noted in 80, 58.33, 72.72 and 70% in the set period from 2004 to 2008.

CONCLUSION

Marked improvement was noticed in all the strategic points from registration, counseling, screening and availability of improved diagnostic kits for screening HIV 1 and HIV 2.

Severe morbidity and mortality in untreated HIV-infected children in a paediatric care programme in Abidjan, Côte d'Ivoire, 2004-2009

Background

Clinical evolution of HIV-infected children who have not yet initiated antiretroviral treatment (ART) is poorly understood in Africa. We describe severe morbidity and mortality of untreated HIV-infected children.

Methods

All HIV-infected children enrolled from 2004-2009 in a prospective HIV programme in two health facilities in Abidjan, Côte d'Ivoire, were eligible from their time of inclusion. Risks of severe morbidity (the first clinical event leading to death or hospitalisation) and mortality were documented retrospectively and estimated using cumulative incidence functions. Associations with baseline characteristics were assessed by competing risk regression models between outcomes and antiretroviral initiation.

Results

405 children were included at a median age of 4.5 years; at baseline, 66.9% were receiving cotrimoxazole prophylaxis, and 27.7% met the 2006 WHO criteria for immunodeficiency by age. The risk of developing a severe morbid event was 14% (95%CI: 10.7 - 17.8) at 18 months; this risk was lower in children previously exposed to any prevention of mother-to-child-transmission (PMTCT) intervention (adjusted subdistribution hazard ratio [sHR]: 0.16, 95% CI: 0.04 - 0.71) versus those without known exposure. Cumulative mortality reached 5.5% (95%CI: 3.5 - 8.1) at 18 months. Mortality was associated with immunodeficiency (sHR: 6.02, 95% CI: 1.28-28.42).

Conclusions

Having benefited from early access to care minimizes the severe morbidity risk for children who acquire HIV. Despite the receipt of cotrimoxazole prophylaxis, the risk of severe morbidity and mortality remains high in untreated HIV-infected children. Such evidence adds arguments to promote earlier access to ART in HIV-infected children in Africa and improve care interventions in a context where treatment is still not available to all.

Changing methods of disclosure. Literature review of disclosure to children with terminal illnesses, including HIV

More than 30 years after the first discovery of the deadly HIV virus, and in the wake of increased knowledge of transmission, treatment and behavioral intervention development, parents are still faced with the difficult task of whether, when and how to inform their child about her or his HIV status. Except for some general ethical considerations, there are no national or international guidelines available for handling HIV status disclosure to a child by parents and health professionals. Most studies on disclosure address the problem of stigma and the barriers to disclosure of HIV-positive status by adults to their sexual partners, caretakers, families and communities, but very few studies focus on disclosure to HIV-positive children. The majority of the studies that address disclosure to children limit themselves to stipulating reasons for barriers to such disclosure instead of the skills and knowledge necessary for effective disclosure to a child. Increasing availability of therapy for HIV across the world presses the issue of disclosure to the child. Even so, disclosure for children who are HIV-positive due to vertical transmission continues to be very difficult. There is a lack of interventions that consider guidelines for healthcare professionals, parents or persons involved with taking care of HIV-positive children. These interventions should be designed in an understanding manner towards the culture where they might be implemented and be as appropriate in the view of integrating different family structures and the child's development.

HIV/AIDS in 3 generations: case series

BACKGROUND

The HIV pandemic is one of the greatest challenges facing humanity, and generations may be wiped out if effective prevention, treatment, and care are not in place.

CASE REPORTS

A total of 3 families are presented. In the first 2, the children represented the third generation in their families to be infected with HIV and probably had mother-to-child transmission of the disease. The children in the third family were HIV negative. The mothers and grandmothers in all the families were infected with HIV. Risky sexual behavior involving multiple sexual partnering was recorded among them, some of whom had died from AIDS-related illness. This has serious implications in the care of the infected and affected children as they had been made vulnerable by their circumstances.

CONCLUSION

HIV/AIDS has been around long enough now to cross generations as shown in the reported cases, which resulted in serious health and socioeconomic effects in the affected families.

Family-centred approaches to the prevention of mother to child transmission of HIV

BACKGROUND

Prevention of mother to child transmission (PMTCT) programmes have traditionally been narrow in scope, targeting biomedical interventions during the perinatal period, rather than considering HIV as a family disease. This limited focus restricts programmes' effectiveness, and the opportunity to broaden prevention measures has largely been overlooked.Although prevention of vertical transmission is crucial, consideration of the family environment can enhance PMTCT. Family-centred approaches to HIV prevention and care present an important direction for preventing paediatric infections while improving overall family health. This paper reviews available literature on PMTCT programmatic models that have taken a broader or family-centred approach. We describe findings and barriers to the delivery of family-centred PMTCT and identify a number of promising new directions that may achieve more holistic services for children and families.

METHODS

Literature on the effectiveness of family-centred PMTCT interventions available via PubMed, EMBASE and PsycINFO were searched from 1990 to the present. Four hundred and three abstracts were generated. These were narrowed to those describing or evaluating PMTCT models that target broader aspects of the family system before, during and/or after delivery of an infant at risk of acquiring HIV infection (N = 14).

RESULTS

The most common aspects of family-centred care incorporated by PMTCT studies and programme models included counselling, testing, and provision of antiretroviral treatment for infected pregnant women and their partners. Antiretroviral therapy was also commonly extended to other infected family members. Efforts to involve fathers in family-based PMTCT counselling, infant feeding counselling, and general decision making were less common, though promising. Also promising, but rare, were PMTCT programmes that use interventions to enrich family capacity and functioning; these include risk assessments for intimate partner violence, attention to mental health issues, and the integration of early childhood development services.

CONCLUSIONS

Despite barriers, numerous opportunities exist to expand PMTCT services to address the health needs of the entire family. Our review of models utilizing these approaches indicates that family-centred prevention measures can be effectively integrated within programmes. However, additional research is needed in order to more thoroughly evaluate their impact on PMTCT, as well as on broader family health outcomes.

Factors determining HIV viral testing of infants in the context of mother-to-child transmission

AIM

The aim of this study was to investigate factors determining HIV viral testing of infants in the context of Prevention of Mother-to-Child Transmission of HIV (PMTCT).

METHODS

Post-delivery HIV infected mothers 18 years and above with babies aged 3-6 months were interviewed on HIV viral testing of infants and factors associated with it.

RESULTS

Among 311 HIV infected women 61.7% had their infant tested for HIV between 4 and 8 weeks. Bivariate analyses found that older age of the mothers, lower depression scores, higher PMTCT knowledge, low PMTCT risk behaviour (maternal and infant nevirapine adherence, health facility delivery and exclusive formula feeding), HIV status disclosure and attending a support group were associated with PCR test participation. In multivariate analyses higher PMTCT knowledge, infant nevirapine adherence, and not exclusive breast feeding were associated with polymerase chain reaction test participation.

CONCLUSION

Various determinants of acceptance of participation in HIV viral testing of infants in the context of PMTCT were identified that can guide infant testing and diagnosis counselling and support services of PMTCT programmes.

Access to HIV/AIDS care for mothers and children in sub-Saharan Africa: adherence to the postnatal PMTCT program

Despite scale up of perinatal prevention of mother-to-child transmission (PMTCT) of HIV interventions, postnatal continuity of comprehensive HIV/AIDS care, for both the mother and baby, remains a challenge in developing countries. We determined adherence to the postnatal PMTCT program (PN-PMTCT) and the associated factors among mothers at a public urban hospital in Uganda. We interviewed HIV-positive postnatal mothers on discharge and we determined adherence to PN-PMTCT by the proportion of mothers that honored their return appointments by the end of eight weeks postpartum. We had focus group discussions to assess factors that influence adherence to PN-PMTCT. Of 289 mothers, only 110 (38%) adhered to PN-PMTCT. Previous attendance of a routine postnatal review and having access to a phone were significantly associated with adherence to PMTCT among mothers older than 25 years (odds ratio (OR) 3.6 (95% confidence interval (CI); 1.2-10.4)) and (OR 3.1 (95% CI; 1.3-7.1)), respectively. On the other hand, Christianity (OR 3.2 (95% CI; 1.1-9.0)) was significantly associated with adherence to PN-PMTCT among mothers below 25 years of age. Mothers' perceived benefits of the PN-PMTCT program, easy access to the program, and presence of social support from a spouse were important motivators for mothers to adhere to PN-PMTCT. Even with improved antenatal and intra-partum PMTCT services, only a third of the HIV-infected mothers adhered to the PN-PMTCT program. Mothers who previously attended a routine postnatal care were 3.6 fold more likely to adhere to PN-PMTCT. We recommend strategies to increase mothers' adherence to PN-PMTCT interventions in order to increase access to HIV/AIDS care for mothers and children in sub-Saharan Africa.

Universal antiretroviral therapy for pregnant and breast-feeding HIV-1-infected women: towards the elimination of mother-to-child transmission of HIV-1 in resource-limited settings

Prevention of mother-to-child transmission (MTCT) of human immunodeficiency virus type 1 (HIV-1) remains a challenge in most resource-limited settings, particularly in Africa. Single-dose and short-course antiretroviral (ARV) regimens are only partially effective and have failed to achieve wide coverage despite their apparent simplicity. More potent ARV combinations are restricted to pregnant women who need treatment for themselves and are also infrequently used. Furthermore, postnatal transmission via breast-feeding is a serious additional threat. Modifications of infant feeding practices aim to reduce HIV-1 transmission through breast milk; replacement feeding is neither affordable nor safe for the majority of African women, and early breast-feeding cessation (eg, prior to 6 months of life) requires substantial care and nutritional counseling to be practiced safely. The recent roll out of ARV treatment has changed the paradigm of prevention of MTCT. To date, postnatal ARV interventions that have been evaluated target either maternal ARV treatment to selected breast-feeding women, with good efficacy, or single-drug postexposure prophylaxis for short periods of time to their neonates, with a partial efficacy and at the expense of acquisition of drug-related viral resistance. We hypothesize that a viable solution to eliminate pediatric AIDS lies in the universal provision of fully suppressive ARV regimens to all HIV-1-infected women through pregnancy, delivery, and the entire breast-feeding period. On the basis of available evidence, we suggest translating into practice the recently available evidence on this matter without any further delay.

Scaling up antiretroviral therapy for HIV-infected children in Côte d'Ivoire: determinants of survival and loss to programme

OBJECTIVE

To investigate deaths and losses to follow-up in a programme designed to scale up antiretroviral therapy (ART) for HIV-infected children in Côte d'Ivoire.

METHODS

Between 2004 and 2007, HIV-exposed children at 19 centres were offered free HIV serum tests (polymerase chain reaction tests in those aged < 18 months) and ART. Computerized monitoring was used to determine: (i) the number of confirmed HIV infections, (ii) losses to the programme (i.e. death or loss to follow-up) before ART, (iii) mortality and loss-to-programme rates during 12 months of ART, and (iv) determinants of mortality and losses to the programme.

FINDINGS

The analysis included 3876 ART-naïve children. Of the 1766 with HIV-1 infections (17% aged < 18 months), 124 (7.0%) died, 52 (2.9%) left the programme, 354 (20%) were lost to follow-up before ART, 259 (15%) remained in care without ART, and 977 (55%) started ART (median age: 63 months). The overall mortality rate during ART was significantly higher in the first 3 months than in months 4-12: 32.8 and 6.9 per 100 child-years of follow-up, respectively. Loss-to-programme rates were roughly double mortality rates and followed the same trend with duration of ART. Independent predictors of 12-month mortality on ART were pre-ART weight-for-age z-score < -2, percentage of CD4+ T lymphocytes < 10, World Health Organization HIV/AIDS clinical stage 3 or 4, and blood haemoglobin < 8 g/dl.

CONCLUSION

The large-scale programme to scale up paediatric ART in Côte d'Ivoire was effective. However, ART was often given too late, and early mortality and losses to programme before and just after ART initiation were major problems.

Effect of provider-initiated testing and counselling and integration of ART services on access to HIV diagnosis and treatment for children in Lilongwe, Malawi: a pre- post comparison

Background

The HIV prevalence in Malawi is 12% and Kamuzu Central Hospital (KCH), in the capital Lilongwe, is the main provider of adult and paediatric HIV services in the central region. The Lighthouse at KCH offers opt-in HIV testing and counselling (HTC) for adults and children. In June 2004, Lighthouse was the first clinic to provide free antiretroviral treatment (ART) in the public sector, but few children accessed the services. In response, provider-initiated HIV testing and counselling (PITC) and an ART clinic were introduced at the paediatric department at KCH in Quarter 4 (Q4) 2004.

Methods

We analysed prospectively collected, aggregated data of quarterly reports from Q1 2003 to Q4 2006 from HTC centre registers, ART registers and clinic registrations at the ART clinics of both Lighthouse and the paediatric department. By comparing data of both facilities before (Q1 2003 to Q3 2004), and after the introduction of the services at the paediatric department (Q4 2004 to Q4 2006), we assessed the effect of this intervention on the uptake of HIV services for children at KCH.

Results

Overall, 3971 children were tested for HIV, 2428 HIV-infected children were registered for care and 1218 started ART. Between the two periods, the median (IQR) number of children being tested, registered and starting ART per quarter rose from 101 (53-109) to 358 (318-440), 56 (50-82) to 226 (192-234) and 18 (8-23) to 139 (115-150), respectively. The median proportion of tested clients per quarter that were children rose from 3.8% (2.7-4.3) to 9.6% (8.8 to 10.0) (p = 0.0009) and the proportion of ART starters that were children rose from 6.9% (4.9-9.3) to 21.1% (19.2-24.2) (p = 0.0036). The proportion of registered children and adults starting ART each quarter increased similarly, from 26% to 53%, and 20% to 52%, respectively.

Conclusions

Implementation of PITC and integration of ART services within the paediatric ward are likely to be the main reasons for improved access to HTC and ART for children at KCH, and can be recommended to other hospitals with paediatric inpatients in resource limited settings with high HIV prevalence.

Routine checks for HIV in children attending primary health care facilities in South Africa: attitudes of nurses and child caregivers

Management of HIV-infected and exposed children is challenging for health workers in primary care settings. Integrated management of childhood illness (IMCI) is a WHO/UNICEF strategy for improving morbidity and mortality in under 5 children attending first level facilities in developing countries. In high HIV-prevalence settings, IMCI includes an HIV component for identification and management of HIV-infected and exposed children, which requires health workers to ask all mothers about their HIV status and check all children for signs of HIV. Effective implementation of the HIV component depends on the ability and willingness of health workers to take every opportunity to identify HIV-infected children during routine care, and implementation in South Africa is poor. In 2006, we conducted 10 focus groups in two provinces in South Africa with IMCI-trained nurses, and with mothers attending first level facilities, to determine their attitudes towards, and experiences of, routine checks for HIV during consultations with sick children. Nurses were frequently unwilling to check for HIV in all children, believing it was unnecessary, unacceptable to mothers, and that they lack skills to implement HIV care. Nurses feared mothers would become upset or make a complaint. Mothers consistently recognised the importance of checking children for HIV and supported implementation of routine checks, although the attitude of the nurse was important in determining the acceptability of HIV-related questions. Mothers expressed fears about lack of confidentiality from nurses, and that receiving HIV-related services could lead to unintentional disclosure of their HIV status. Nurses lack the skills in HIV management and communication skills to implement the HIV component of IMCI. We identify issues relate to improved training, clear policies on record keeping, and organization of health services to respect privacy and confidentiality, to improve the willingness of health workers to provide HIV care and mothers to accept it.

Infant feeding, HIV transmission and mortality at 18 months: the need for appropriate choices by mothers and prioritization within programmes

OBJECTIVES

To determine the late HIV transmission and survival risks associated with early infant feeding practices.

DESIGN

A nonrandomized intervention cohort.

METHODS

HIV-infected pregnant women were supported in their infant feeding choices. Infant feeding data were obtained weekly; blood samples from infants were taken monthly to diagnose HIV infection. Eighteen-month mortality and HIV transmission risk were assessed according to infant feeding practices at 6 months.

RESULTS

One thousand one hundred and ninety-three live-born infants were included. Overall 18-month probabilities of death (95% confidence interval) were 0.04 (0.03-0.06) and 0.53 (0.46-0.60) for HIV-uninfected and HIV-infected children, respectively. The eighteen-month probability of survival was not statistically significantly different for HIV-uninfected infants breastfed or replacement fed from birth. In univariate analysis of infant feeding practices, the probability of HIV-free survival beyond the first 6 months of life in children alive at 6 months was 0.98 (0.89-1.00) amongst infants replacement fed from birth, 0.96 (0.90-0.98; P = 0.25) and 0.91 (0.87-0.94; P = 0.03) in those breastfed for less or more than 6 months, respectively. In multivariable analyses, maternal unemployment and low antenatal CD4 cell count were independently associated with more than three-fold increased risk of infant HIV infection or death.

CONCLUSION

Breastfeeding and replacement feeding of HIV-uninfected infants were associated with similar mortality rates at 18 months. However, these findings were amongst mothers and infants who received excellent support to first make, and then practice, appropriate infant feeding choices. For programmes to achieve similar results, the quality of counselling and identification of mothers with low CD4 cell count need to be the targets of improvement strategies.
