Understanding aims, successes and challenges of palliative care and homelessness initiatives across the UK: an exploratory study.

BACKGROUND: Due to the recognition that people experiencing homelessness (PEH) often die young and unsupported, a growing number of initiatives focusing on palliative care and homelessness are emerging across the UK. However, there has been no systematic exploration of the nature and landscape of this work. AIMS: To understand the range, aims, successes and challenges of current initiatives within the field of palliative care and homelessness in the UK, by exploring existing projects and initiatives. METHOD: An online survey was distributed to members of an Extension for Community Healthcare Outcomes network focusing on palliative care and homelessness for a mixed professional audience. The survey collated the aims, successes and challenges of initiatives aiming to improve palliative care for PEH. Responses were summarised using descriptive statistics, and free-text responses were analysed using thematic analysis. RESULTS: 162 professionals completed the survey. Of these, 62% reported involvement in at least one palliative care and homelessness initiative. Initiatives focused on service delivery (59%), training (28%) and research (28%). Themes for success included improved service engagement, relationship formation, housing provision, honouring end-of-life wishes, upskilling staff and enabling safe hospital discharge. The main challenges included stigma around substance misuse, securing funding, staff capacity, equipment and facilities, and engaging communities. CONCLUSION: The number and scope of initiatives aiming to support PEH with advanced ill health and palliative care needs across the UK is growing, with a range of professionals engaging in the field. Future research may benefit from exploring initiatives in more detail to understand the specific drivers of impact on PEH and the staff and services supporting them.

Involving people with lived experience of homelessness in palliative and end of life care research: key considerations from experts in the field.

BACKGROUND: Co-production of research aims to include people with lived experience of a phenomena throughout the research process. People experiencing homelessness often experience advance ill-health at a young age, yet access palliative care services at a disparately low rate to the level of palliative care need. The voices of people experiencing homelessness are infrequently heard throughout palliative care research, despite the complexities and intricacies of the area. AIM: To explore the experiences of experts in the field to identify key context considerations for involving people with lived experience of homelessness in palliative and end of life care research. METHODS: Qualitative study comprising two data collection streams: interviews with professionals with experience of involving people experiencing homelessness in their work, and focus groups with people with lived experience (PWLE) of homelessness. Data were analysed using iterative, reflexive thematic analysis. Patient and Public Involvement contributors gave feedback on themes. RESULTS: A total of 27 participants took part in semi-structured interviews (N = 16; professionals) or focus groups (N = 11; PWLE homelessness). Key considerations of involving people experiencing homelessness in palliative and end of life care research were developed into four key themes: complexity of lived experience of homelessness; representation of homelessness within experts by experience; professionalising lived experience; and methods for involvement. CONCLUSIONS: Involvement of people with lived experience of homelessness is important in developing palliative care research. This paper begins to outline some contextual considerations for promoting involvement in a complex and intricate field of research.

People experiencing homelessness often become unwell at a young age. They often experience several illnesses at the same time, and many people experiencing homelessness may also experience substance misuse disorders and/or mental illness.Despite this, they often are not identified as needing palliative care support, therefore rarely access services. Research into palliative care and homelessness may benefit from including people with lived experience of homelessness, yet this is rarely done, and is a sensitive and challenging area. The current study carried out interviews with professionals who have previously involved those with lived experience of homelessness in their work, and focus groups with people with lived experience of homelessness. Twenty seven participants took part: 16 professionals with extensive experience of supporting PEH and 11 people with lived experience. Key considerations of involving people experiencing homelessness in palliative care research were developed into four key themes: complexity of lived experience of homelessness; representation of homelessness within experts by experience; professionalising lived experience; and methods for involvement. Involvement of people with lived experience of homelessness is important in developing palliative care research. This paper begins to outline some contextual considerations for promoting involvement in a complex and intricate field of research.

Palliative care, homelessness, and restricted or uncertain immigration status.

Background: People experiencing homelessness have limited access to palliative care support despite high levels of ill health and premature mortality. Most research exploring these challenges in the United Kingdom has focused on people living in hostels or temporary accommodation. People with uncertain or restricted immigration status are often unable to access this accommodation due to lack of entitlement to benefits. There is little research about the experiences of those in the United Kingdom who cannot access hostels or temporary accommodation due to restricted or uncertain immigration status with regards to palliative and end-of-life care access. Aim: To explore the barriers to palliative and end-of-life care access for people with uncertain or restricted immigration status, who are experiencing homelessness and have advanced ill health, and the experiences of UK hospices of supporting people in this situation. Design: A multi-method cross-sectional study. Setting/participants: An online survey for hospice staff followed by online focus groups with staff from inclusion health, homelessness and palliative care services, charities and interviews with people experiencing homelessness. Results: Fifty hospice staff responded to the online survey and 17 people participated in focus groups and interviews (focus groups: n = 10; interviews: n = 7). The survey demonstrated how hospices are not currently supporting many people with restricted or uncertain immigration status who are homeless and that hospice staff have received limited training around eligibility for entitlements or National Health Service (NHS) care. Interview and focus group data demonstrated high levels of unmet need. Reasons for this included a lack of consistency around eligibility for support from local authorities, issues relating to NHS charging, and mistrust and limited knowledge of the UK health and social care system. These barriers leave many people unable to access care toward the end of their lives. Conclusion: To advocate for and provide compassionate palliative and end-of-life care for people with uncertain immigration status, there is need for more legal literacy, with training around people's entitlement to care and support, as well as easier access to specialist legal advice.

Palliative care, homelessness and restricted or uncertain immigration status Most research from the UK about access to support at the end of life for people who are homeless has looked at the experiences of people who are staying in hostels or temporary accommodation. People that are not UK nationals are not entitled to the benefit which pays for hostel or temporary accommodation. There is a group of people in the UK who are very unwell, who are homeless and are not able to access hostel accommodation due to their immigration status. This project explored the experiences of this group around access to palliative care. We spoke to professionals from health and social care services, charities and local councils and people who are in this situation themselves. Hospice staff were also surveyed to see if they had experience of supporting people in this situation. The survey showed that hospices are not currently supporting many people with restricted or uncertain immigration status who are homeless, and that they have limited training around supporting people in this situation. In the interviews and focus groups, opinions were heard about challenges to palliative care support for people with uncertain or restricted immigration status who were experiencing homelessness. Professionals described how it can be hard to obtain support from local authorities, and also understanding rules about who has to pay to receive NHS care. People with uncertain or restricted immigration status who were also homeless did not always know how to access the UK health and social care system and had negative experiences of doing so in the past. As a result, many people are unable to access care towards the end of their lives. To provide compassionate palliative and end-of-life care for people with uncertain immigration status, there is need for more legal literacy, with training around people's entitlement to care and support, as well as easier access to specialist legal advice.

A qualitative exploration of older people's lived experiences of homelessness and memory problems - stakeholder perspectives.

BACKGROUND: The numbers of older people experiencing both homelessness and memory problems are growing, yet their complex health, housing and care needs remain undelineated and unmet. There is a critical gap in understanding what can improve the care, support and experiences of this group. In this qualitative study we explore how stakeholders understand memory problems among older people in the context of homelessness and consider what they judge gets in the way of achieving positive outcomes. METHOD: We conducted reflexive thematic analysis of qualitative interviews (n = 49) using a semi-structured topic guide, with 17 older people (aged ≥ 50 years) experiencing memory problems and homelessness, 15 hostel staff and managers, and 17 health, housing and social care practitioners. We recruited participants from six homelessness hostels, one specialist care home and National Health and Local Authority Services in England. RESULTS: We identified four overarching themes. The population is not taken seriously; multiple causes are hard to disentangle; risk of exploitation and vulnerability; and (dis)connection and social isolation. The transience and lack of stability associated with homelessness intensified the disorienting nature of memory and cognitive impairment, and those providing direct and indirect support required flexibility and persistence, with staff moving beyond traditional roles to advocate, provide care and safeguard individuals. Memory problems were perceived by frontline staff and older people to be overlooked, misinterpreted, and misattributed as being caused by alcohol use, resulting in pervasive barriers to achieving positive and desired outcomes. CONCLUSIONS: Efforts to meet the needs of older people living with memory problems and experiencing homelessness and future interventions must reflect the complexity of their lives, often in the context of long-term alcohol use and current service provision and we make suggestions as to what could be done to improve the situation.

People living in homeless hostels: a survey of health and care needs.

People experiencing homelessness have extremely poor health outcomes and frequently die young. Many single homeless people live in hostels, the remit of which is to provide support to facilitate recovery out of homelessness. They are not usually designed to support people with high health or care needs. A cross-sectional survey was developed with, and completed by, hostel managers to explore and quantify the level of health and care needs of people living in their hostels. In total, 58 managers completed the survey, with information on 2,355 clients: 64% had substance use disorder, 56% had mental health issues, and 37.5% were in poor physical health. In addition, 5% had had more than three unplanned hospital visits in the previous month, and 11% had had safeguarding referrals submitted over the past year. Barriers to getting support and referrals accepted were highlighted, particularly for people with substance use disorder. Hostel managers identified 9% of clients as having needs too high for their service, while move-on options were scarce. Our study highlights significant unmet needs. Health and care services are not providing adequate support for many people living in hostels, who often have very poor health outcomes. This inequity needs to be considered and addressed as a matter of urgency.

Health and care needs of hospitalised people experiencing homelessness: an inpatient audit.

BACKGROUND: People experiencing homelessness frequently die young, from preventable and treatable conditions. They experience significant barriers to healthcare and are often critically ill when admitted to hospital. A hospital admission is an opportunity to intervene and prevent premature mortality by providing compassionate care and facilitating access to safe onward accommodation and support. METHODS: To quantify needs, a cross-sectional audit of inpatients experiencing homelessness across 15 acute hospital teams in London, was undertaken in February 2022. Integrated discharge and hospital homelessness teams were interviewed about each patient identified as homeless or vulnerably housed. Data was collected about patients' health, housing, support needs, and reasons for delayed discharges. RESULTS: Detailed information was gathered on 86 patients. There was a high level of clinical complexity and multimorbidity. For a safe discharge 60% of individuals were deemed to need accommodation providing high or medium level support and at the time of the audit, half were delayed discharges. CONCLUSION: There is an urgent need for a range of intermediate/step down and longer-term accommodation and support to enable safe appropriate discharge from hospital and start to address the huge inequity in health outcomes of this population. This paper includes recommendations for clinicians and commissioners.

Opportunities and challenges in involving people with lived experience of inclusion health as co-researchers in palliative and end of life research: a rapid review and thematic synthesis.

BACKGROUND: Co-research is a collaborative approach to research, promoting involvement of individuals with lived experience of a research area as experts by experience. Recently, the importance of co-research within palliative and end of life care (PEoLC) has been highlighted, yet few recommendations exist regarding best practice for involving inclusion health groups (i.e., groups that are socially excluded, typically experiencing multiple disadvantages that contribute to poor health outcomes). AIMS: To identify and synthesise qualitative literature outlining barriers and facilitators for involving four inclusion health groups (individuals with lived experience of: homelessness, substance use disorder, incarceration or exchanging sex for money) in PEoLC research, from the perspectives of both the researchers and individuals with lived experience. METHODS: This report is a rapid review with thematic synthesis methodology. Three electronic databases were searched (2012-30th August 2022). Thematic synthesis was used to generate themes across qualitative studies. RESULTS: Three qualitative studies were eligible for inclusion. Two involved individuals with lived experience of incarceration, and one lived experience of homelessness. No papers outlined best-practice guidance for co-research; all offered reflections on the co-research process. Challenges for involvement included: facilitating appropriate reimbursement; overcoming stigma; fear of tokenism; pre-conceived views and the emotional burden of research. Successes and benefits included: advanced level of insight, a two-way learning opportunity and relatability of lived experience co-researchers. CONCLUSIONS: This review did not identify any best-practice guidance for co-production of PEoLC research with inclusion health groups. There are few, good quality, qualitative studies offering insight into challenges and facilitators for lived experience co-researcher involvement. Further research and formal policy development is required to produce formal best-practice guidance to support safe, impactful inclusion in PEoLC research. It is important that researchers work together with people who have lived experience of the topic they are researching. Palliative care is specialised medical care for people living with a terminal illness. There is some collaboration between researchers and people with lived experience in palliative and end-of-life care research. However, some groups of people have been excluded. This includes people experiencing homelessness, or people with drug or alcohol addictions. This review aimed to understand what works and what doesn't work when involving four excluded groups in palliative and end-of-life research. These groups were people experiencing homelessness, those who had spent time in prison, people with drug or alcohol disorders, and people who exchanged sex for money. This review used a shortened methodology, which allowed it to be done quickly. Three online academic databases (Medline, PubMed, PsychINFO) were searched for research projects: three papers were included in the review. No clear guidance for working with these groups was found. Analysis identified themes across papers. Challenges for collaboration included: appropriate payment methods; overcoming stigma; fear of being talked down to,; assumptions made before meeting people, and the potential of becoming upset. Successes and benefits included: better understanding of the research topic, the opportunity to learn from one another, and how research participants could relate to lived experience co-researchers. There are few, good quality papers, but more research is needed to produce guidance to support safe, impactful collaboration.

Barriers and facilitators to accessing health and social care services for people living in homeless hostels: a qualitative study of the experiences of hostel staff and residents in UK hostels.

INTRODUCTION: The number of people living in homeless hostels in the UK has steadily increased over the past decade. Despite people experiencing homelessness often having considerable health problems and a range of complex needs frequently in association with addictions, the experiences of hostel staff and residents especially in relation to accessing health and social care support have seldom been explored. The aim of this paper is to identify the barriers and facilitators to accessing health and social care services for people living in homeless hostels. DESIGN: Exploratory qualitative baseline data were collected as part of an intervention to facilitate palliative care in-reach into hostels. SETTING/PARTICIPANTS: Interviews were conducted with 33 participants; 18 homeless hostel managers/support staff and 15 people experiencing homelessness, from six homeless hostels in London and Kent. RESULTS: Three themes were identified (1) internal and external service barriers to health and social care access due to stigma, lack of communication and information sharing from services and assumptions around capacity and the role of the hostel, (2) the impact of lack of health and social care support on hostel staff leading to burnout, staff going beyond their job role and continuous support given to residents, (3) potential facilitators to health and social care access such in-reach and support from those who understand this population and hostel staff training. DISCUSSION: Residents have multiple complex needs yet both hostel staff and residents face stigma and barriers accessing support from external services. Positive relationships were described between hostel residents and staff, which can be an essential step in engaging with other services. People experiencing homelessness urgently need better access to person-centred, trauma-informed support ideally via in-reach from people who understand the needs of the population.

The benefits and challenges of embedding specialist palliative care teams within homeless hostels to enhance support and learning: Perspectives from palliative care teams and hostel staff.

BACKGROUND: People residing in UK homeless hostels experience extremely high rates of multi-morbidity, frailty and age-related conditions at a young age. However, they seldom receive palliative care with the burden of support falling to hostel staff. AIM: To evaluate a model embedding palliative specialists, trained as 'homelessness champions', into hostels for two half-days a month to provide support to staff and residents and facilitate a multidisciplinary approach to care. DESIGN: An exploratory qualitative design. SETTING/PARTICIPANTS: Four homeless hostels in London, UK, including nine hostel managers/support staff and seven palliative care specialists (five nurses and two social workers). RESULTS: Benefits to introducing the model included: developing partnership working between hostel staff and palliative care specialists, developing a holistic palliative ethos within the hostels and improving how hostel staff seek support and connect with local external services. Challenges to implementation included limited time and resources, and barriers related to primary care. CONCLUSION: This is the first evaluation of embedding palliative care specialists within homeless hostels. Inequity in health and social care access was highlighted with evidence of benefit of this additional support for both hostel staff and residents. Considering COVID-19, future research should explore remote ways of working including providing in-reach support to homelessness services from a range of services and organisations.

Evaluation of training on palliative care for staff working within a homeless hostel.

BACKGROUND: In the UK, many people experiencing homelessness whose health is deteriorating remain in homeless hostels due to few suitable alternative places of care. Hostel staff struggle to support residents with deteriorating health and palliative care services are rarely involved. There is recognition of the need for multiagency working to support this group. OBJECTIVES: To pilot and evaluate the impact of a two-day training course for hostel staff around supporting clients with palliative care needs, and increasing multiagency working. DESIGN: Mixed methods evaluation using pre-and-post training data collection. SETTINGS AND PARTICIPANTS: Frontline staff from two London homeless hostels. METHODS: Staff from two hostels attended a two day training course. Self-perceived confidence in supporting residents with deteriorating health, knowledge of palliative care, openness to discussing deteriorating health and work related stress were assessed at baseline and immediately after training using a novel questionnaire. Qualitative data was collected via focus groups immediately after and three months post-training. RESULTS: Twenty four participants attended at least one day of training, 21 (87%) completed the course. Training was reported to be useful and relevant. Modest improvements in self-perceived work related stress, knowledge, confidence and openness were observed following training. At three months, qualitative data indicated the beginnings of a shift in how palliative care was conceptualised and an increase in knowledge and confidence around supporting residents. Anxiety regarding the role of the hostel in palliative care, the recovery focused ethos of homelessness services and fragmented systems and services presented challenges to establishing changes. CONCLUSIONS: Training can be useful for improving knowledge, confidence, openness and work related stress. Recommendations for implementing changes in how people experiencing homelessness are supported include embedding training into routine practice, promoting multidisciplinary working, incorporating flexibility within the recovery focused approach of services and recognising the need for emotional support for staff.

End-of-life care for homeless people: A qualitative analysis exploring the challenges to access and provision of palliative care.

BACKGROUND: Being homeless or vulnerably housed is associated with death at a young age, frequently related to medical problems complicated by drug or alcohol dependence. Homeless people experience high symptom burden at the end of life, yet palliative care service use is limited. AIM: To explore the views and experiences of current and formerly homeless people, frontline homelessness staff (from hostels, day centres and outreach teams) and health- and social-care providers, regarding challenges to supporting homeless people with advanced ill health, and to make suggestions for improving care. DESIGN: Thematic analysis of data collected using focus groups and interviews. PARTICIPANTS: Single homeless people ( n = 28), formerly homeless people ( n = 10), health- and social-care providers ( n = 48), hostel staff ( n = 30) and outreach staff ( n = 10). RESULTS: This research documents growing concern that many homeless people are dying in unsupported, unacceptable situations. It highlights the complexities of identifying who is palliative and lack of appropriate places of care for people who are homeless with high support needs, particularly in combination with substance misuse issues. CONCLUSION: Due to the lack of alternatives, homeless people with advanced ill health often remain in hostels. Conflict between the recovery-focused nature of many services and the realities of health and illness for often young homeless people result in a lack of person-centred care. Greater multidisciplinary working, extended in-reach into hostels from health and social services and training for all professional groups along with more access to appropriate supported accommodation are required to improve care for homeless people with advanced ill health.

Challenges to discussing palliative care with people experiencing homelessness: a qualitative study.

OBJECTIVES: To explore the views and experiences of people who are homeless and those supporting them regarding conversations and approaches to palliative care SETTING: Data were collected between October 2015 and October 2016 in homeless hostels and day centres and with staff from primary and secondary healthcare providers and social care services from three London boroughs. PARTICIPANTS: People experiencing homelessness (n=28), formerly homeless people (n=10), health and social care providers (n=48), hostel staff (n=30) and outreach staff (n=10). METHODS: In this qualitative descriptive study, participants were recruited to interviews and focus groups across three London boroughs. Views and experiences of end-of-life care were explored with people with personal experience of homelessness, health and social care professionals and hostel and outreach staff. Saturation was reached when no new themes emerged from discussions. RESULTS: 28 focus groups and 10 individual interviews were conducted. Participants highlighted that conversations exploring future care preferences and palliative care with people experiencing homelessness are rare. Themes identified as challenges to such conversations included attitudes to death; the recovery focused nature of services for people experiencing homelessness; uncertainty regarding prognosis and place of care; and fear of negative impact. CONCLUSIONS: This research highlights the need for a different approach to supporting people who are homeless and are experiencing advanced ill health, one that incorporates uncertainty and promotes well-being, dignity and choice. We propose parallel planning and mapping as a way of working with uncertainty. We acknowledge that these approaches will not always be straightforward, nor will they be suitable for everyone, yet moving the focus of conversations about the future away from death and dying, towards the present and the future may facilitate conversations and enable the wishes of people who are homeless to be known and explored.

Challenges to access and provision of palliative care for people who are homeless: a systematic review of qualitative research.

BACKGROUND: People who are homeless or vulnerably housed are a marginalized group who often experience high rates of morbidity and die young as a result of complex problems. Access to health care and support can be challenging, with access to palliative care even more so. This review presents a synthesis of published qualitative research exploring from the perspective of homeless people and those working to support them, current challenges to palliative care access and provision, in addition to suggestions for what may improve palliative care for this population. METHODS: Systematic review of qualitative research analysed using thematic synthesis. PsycINFO, Medline, Sociological Abstracts, Social Services Abstracts, Science citations index and CINAHL were searched up to September 2016. Thematic synthesis involved a three-step inductive process to develop a deeper understanding of the challenges to and suggestions for the access and provision of palliative care for homeless people. RESULTS: Thirteen qualitative articles, reporting nine studies were identified. The challenges to access and provision to palliative care were drawn from the data covering three broad areas, namely "the chaotic lifestyles sometimes associated with being homeless", "the delivery of palliative care within a hostel for homeless people" and provision within "mainstream health care systems". Obstacles were related to homeless persons competing day-to-day priorities, their experience of stigma in mainstream settings, the high burden on hostel staff in supporting residents at the end of life and inflexibility in mainstream health care systems. Suggestions for improving access to palliative care include building trust between homeless persons and health professionals, increasing collaboration between and flexibility within services, and providing more training and support for all professionals. CONCLUSIONS: The provision of palliative care can be complicated for all populations, however delivering palliative care for people who are homeless is influenced by a potentially greater and more varied range of factors, on both individual and systemic levels, than providing palliative care for the housed population. Careful consideration and potentially great changes will be needed within health care systems to ensure homeless populations have equitable access to palliative care.

Maternal HIV infection and placental malaria reduce transplacental antibody transfer and tetanus antibody levels in newborns in Kenya.

BACKGROUND: In clinical trials, maternal tetanus toxoid (TT) vaccination is effective in protecting newborns against tetanus infection, but inadequate placental transfer of tetanus antibodies may contribute to lower-than-expected rates of protection in routine practice. We studied the effect of placental malaria and maternal human immunodeficiency virus (HIV) infection on placental transfer of antibodies to tetanus. METHODS: A total of 704 maternal-cord paired serum samples were tested by ELISA for antibodies to tetanus. The HIV status of all women was determined by an immunoglobulin G antibody-capture particle-adherence test, and placental malaria was determined by placental biopsy. Maternal history of TT vaccination was recorded. RESULTS: Tetanus antibody levels were reduced by 52% (95% confidence interval [CI], 30%-67%) in newborns of HIV-infected women and by 48% (95% CI, 26%-62%) in newborns whose mothers had active-chronic or past placental malaria. Thirty-seven mothers (5.3%) and 55 newborns (7.8%) had tetanus antibody levels <0.1 IU/mL (i.e., were seronegative). Mothers' self-reported history of lack of tetanus immunization was the strongest predictor of seronegativity and of tetanus antibody levels in maternal and cord serum. CONCLUSION: Malarial and HIV infections may hinder efforts to eliminate maternal and neonatal tetanus, making implementation of the current policy for mass vaccination of women of childbearing age an urgent priority.

A randomised, double-blind, placebo-controlled trial of atovaquone-proguanil vs. sulphadoxine-pyrimethamine in the treatment of malarial anaemia in Zambian children.

OBJECTIVE: To compare the efficacy of atovaquone-proguanil (AP) and sulphadoxine-pyrimethamine (SP) in the treatment of malarial anaemia in Zambian children. METHODS: An individually randomised, double-blind, controlled trial was undertaken in Zambian children with moderately severe anaemia and Plasmodium falciparum parasitaemia. The main trial endpoint was treatment failure defined as a need for blood transfusion or treatment with quinine, persistent anaemia or death within 14 days from the start of treatment. Secondary endpoints were parasitological and haematological findings 14 or 28 days after the start of treatment. RESULTS: A total of 128 children with a packed cell volume of <21% and >9% and P. falciparum parasitaemia received treatment with AP and 127 treatment with SP. Treatment failure occurred in 28 children (22%) who received SP and in 10 (8%) who received AP (OR: 3.34, 95% CI: 1.54, 7.21). Ten children required blood transfusion, all of whom were in the SP treatment group. Six children died, five of whom were in the AP group; none of the deaths were considered to be related directly to treatment. CONCLUSIONS: Atovaquone-proguanil proved more effective than SP in the treatment of malarial anaemia in an area with a modest level of SP resistance. AP is no longer available through the Malarone Donation Programme and is too expensive for routine use in Africa. However, this study has shown that in an area with a modest level of resistance to SP, use of a more effective antimalaria reduces the need for blood transfusion in children with malarial anaemia.

Lack of inhibition of the anti-malarial action of sulfadoxine-pyrimethamine by folic acid supplementation when used for intermittent preventive treatment in Gambian primigravidae.

Folic acid is frequently given to pregnant women at the same time as intermittent preventive treatment (IPTp) with sulfadoxine/pyrimethamine (SP), but it is not known if it interferes with the anti-malarial activity of SP. To investigate this concern, 1,035 Gambian primigravidae were randomized to receive either folic acid (500-1,500 microg/day) together with oral iron (522) or oral iron alone (513) for 14 days at the same time as they received IPTp with SP. On presentation, 261 women (25%) had Plasmodium falciparum asexual parasitemia. Prevalences of parasitemia on day 14 after treatment were similar in both groups: 5.7% (26 of 458) in the iron plus folic acid group and 4.9% (22 of 446) in the iron alone group (risk difference = 0.74%, 95% confidence interval [CI] = -2.2% to 3.7%). Parasitologic cure was observed in 116 (91%) of 128 of women who were parasitemic on presentation and who received iron and folic acid and in 122 (92%) of 133 women who received iron alone (difference = 1.1%, 95% CI = -5.6% to 8.0%). Women who received folic acid and iron had a slightly higher mean hemoglobin concentration at day 14 than women who had received iron alone (difference = 0.14 g/dL, 95% CI = 0.01-0.27 g/dL). The results of this study suggest that in an area of low SP resistance, administration of folic acid to pregnant women in a dose of 500-1,500 mug/day will not interfere with the protective effect of SP when used for IPTp.

Folic acid treatment of Zambian children with moderate to severe malaria anemia.

Whether administration of folic acid to children with malaria anemia is helpful is controversial. Therefore, we conducted a randomised, placebo-controlled trial of 14 days of treatment with folic acid (1 mg/d) in Zambian children with malaria anemia treated with either sulfadoxine/pyrimethamine (SP) or atovaquone/proguanil (AP). Among children who received SP, the prevalence of parasitemia was higher in children treated with folic acid than among those given placebo at days 3, 7, and 14 after the start of treatment, and the difference at day 3 was statistically significant (P = 0.013). Folic acid treatment had no effect on parasitemia in children treated with AP. Administration of folic acid led to a small increase in packed cell volume over that seen in the placebo group at days 14 and 28 after the start of treatment.

Factors associated with severe anaemia in Zambian children admitted with Plasmodium falciparum malarial anaemia.

Many cases of severe malarial anaemia are clinically stable, but some can deteriorate rapidly. In a cross-sectional survey of 255 children with clinically stable malarial anaemia, 72 had severe anaemia (PCV < or = 15%) and 183 were moderately anaemic (PCV < 15-21%). Being female, or febrile, or a referral and having low parasitaemia or hepatomegaly were the risk factors for severe anaemia.

Neonatal measles immunity in rural Kenya: the influence of HIV and placental malaria infections on placental transfer of antibodies and levels of antibody in maternal and cord serum samples.

INTRODUCTION: Young infants are protected from measles infection by maternal measles antibodies. The level of these antibodies at birth depends on the level of antibodies in the mother and the extent of placental transfer. We investigated predictors of levels of measles antibodies in newborns in rural Kenya. METHODS: A total of 747 paired maternal-cord serum samples (91 from human immunodeficiency virus [HIV]-infected and 656 from HIV-uninfected mothers) were tested for measles immunoglobulin G antibodies. Placental malaria infection was determined by biopsy. Data on pregnancy history, gestational age, and anthropometric and socioeconomic status were collected. RESULTS: Infants born to HIV-infected mothers were more likely (odds ratio, 4.6 [95% confidence interval {CI}, 2.2-9.7]) to be seronegative and had 35.1% (95% CI, 9.8%-53.2%) lower levels of measles antibodies than did those born to HIV-uninfected mothers. Preterm delivery, early maternal age, and ethnic group were also associated with reduced levels of measles antibodies. There was little evidence that placental malaria infection was associated with levels of measles antibodies in newborns. CONCLUSION: Our results suggest that maternal HIV infection may reduce levels of measles antibodies in newborns. Low levels of measles antibodies at birth render children susceptible to measles infection at an early age. This is of concern in sub-Saharan African countries, where not only is the prevalence of HIV high, but measles is the cause of much morbidity and mortality.

Intermittent preventive sulfadoxine-pyrimethamine treatment of primigravidae reduces levels of plasma immunoglobulin G, which protects against pregnancy-associated Plasmodium falciparum malaria.

Pregnancy-associated malaria (PAM) is an important cause of maternal and neonatal suffering. It is caused by Plasmodium falciparum capable of inhabiting the placenta through expression of particular variant surface antigens (VSA) with affinity for proteoglycans such as chondroitin sulfate A. Protective immunity to PAM develops following exposure to parasites inhabiting the placenta, and primigravidae are therefore particularly susceptible to PAM. The adverse consequences of PAM in primigravidae are preventable by intermittent preventive treatment (IPTp), where women are given antimalarials at specified intervals during pregnancy, but this may interfere with acquisition of protective PAM immunity. We found that Kenyan primigravidae receiving sulfadoxine-pyrimethamine IPTp had significantly lower levels of immunoglobulin G (IgG) with specificity for the type of parasite-encoded VSA-called VSA(PAM)-that specifically mediate protection against PAM than did women receiving a placebo. VSA(PAM)-specific IgG levels depended on the number of IPTp doses received and were sufficiently low to be of clinical concern among multidose recipients. Our data suggest that IPTp should be extended to women of all parities, in line with current World Health Organization recommendations.
