Characterization of Enzyme-Linked Immunosorbent Assay (ELISA) for Quantification of Antibodies against Salmonella Typhimurium and Salmonella Enteritidis O-Antigens in Human Sera.

Nontyphoidal Salmonella (NTS) is a leading cause of morbidity and mortality caused by enteric pathogens worldwide in both children and adults, and vaccines are not yet available. The measurement of antigen-specific antibodies in the sera of vaccinated or convalescent individuals is crucial to understand the incidence of disease and the immunogenicity of vaccine candidates. A solid and standardized assay used to determine the level of specific anti-antigens IgG is therefore of paramount importance. In this work, we presented the characterization of a customized enzyme-linked immunosorbent assay (ELISA) with continuous readouts and a standardized definition of EU/mL. We assessed various performance parameters: standard curve accuracy, dilutional linearity, intermediate precision, specificity, limits of blanks, and quantification. The simplicity of the assay, its high sensitivity and specificity coupled with its low cost and the use of basic consumables and instruments without the need of high automation makes it suitable for transfer and application to different laboratories, including resource-limiting settings where the disease is endemic. This ELISA is, therefore, fit for purpose to be used for quantification of antibodies against Salmonella Typhimurium and Salmonella Enteritidis O-antigens in human samples, both for vaccine clinical trials and large sero-epidemiological studies.

What is the Source of Infections Causing Invasive Nontyphoidal Salmonella Disease?

Invasive nontyphoidal Salmonella (iNTS) disease is a clinical condition distinct from Salmonella gastroenteritis. With an overall case-fatality rate of 14.5%, iNTS remains a major cause of morbidity and mortality, particularly in sub-Saharan Africa. However, the sources of infections that lead to cases of iNTS remain unclear. Broadly, there are 2 hypotheses as to the source of infections: (i) transmission from a zoonotic reservoir, similar to other nontyphoidal salmonelloses; or (ii) person-to-person transmission. Here we review several recent studies that have asked, "What is the source of infections causing invasive nontyphoidal Salmonella disease?" Two studies reported isolates in the stool of household members of iNTS cases that were very closely related (<3 single-nucleotide polymorphisms) to the iNTS case isolates; this is consistent with the hypothesis of person-to-person transmission, but infection from a common source (eg, a foodstuff) cannot be excluded. On the other hand, thorough investigations of the domestic environment of iNTS cases and the food pathway found only a single iNTS-associated Salmonella Enteritidis isolate. Therefore, we recommend that future studies test the hypothesis that iNTS is transmitted between people within the domestic environment. Further studies of food and water pathways are also warranted.

Development and Characterization of a Luminescence-Based High-Throughput Serum Bactericidal Assay (L-SBA) to Assess Bactericidal Activity of Human Sera against Nontyphoidal Salmonella.

Salmonella Typhimurium and Salmonella Enteritidis are leading causative agents of invasive nontyphoidal Salmonella (iNTS) disease, which represents one of the major causes of death and morbidity in sub-Saharan Africa, still partially underestimated. Large sero-epidemiological studies are necessary to unravel the burden of disease and guide the introduction of vaccines that are not yet available. Even if no correlate of protection has been determined so far for iNTS, the evaluation of complement-mediated functionality of antibodies generated towards natural infection or elicited upon vaccination may represent a big step towards this achievement. Here we present the setup and the intra-laboratory characterization in terms of repeatability, intermediate precision, linearity, and specificity of a high-throughput luminescence-based serum bactericidal assay (L-SBA). This method could be useful to perform sero-epidemiological studies across iNTS endemic countries and for evaluation of antibodies raised against iNTS vaccine candidates in upcoming clinical trials.

"Testing Can Be Done Anywhere": A Qualitative Assessment of Targeted Community-Based Point-of-Care Early Infant Diagnosis of HIV in Lusaka, Zambia.

INTRODUCTION: Delayed HIV diagnosis in HIV-exposed infants (HEIs) results in missed opportunities for early antiretroviral therapy (ART), causing significant morbidity and mortality. Early infant diagnosis (EID) depends on the availability of accessible and reliable testing services. We explored the acceptability, appropriateness, and feasibility of deploying a targeted community-based point-of-care (POC) EID testing model (i.e., "community POC model") to reach high-risk mother-infant pairs (MIPs) in Lusaka, Zambia. METHODS: We conducted in-depth interviews with a purposive sample of health care workers, study staff, and caregivers in high-risk MIPs at 6 health facilities included in a larger implementation research study evaluating the community POC model. We defined "high-risk MIPs" as mothers who did not receive antenatal testing or an attended delivery or infants who missed EID testing milestones. Interviews were audio-recorded, translated, and transcribed verbatim in English. Content and thematic analysis were done using NVivo 10 software. RESULTS: Health care workers (n=20) and study staff (n=12) who implemented the community POC model noted that the portability and on-screen prompts of the POC platform made it mobile and easy to use, but maintenance and supply chain management were key to field operations. Respondents also felt that the community POC model reached more infants who had never had EID testing, allowing them to find infants with HIV infection and immediately initiate them on ART. Caregivers (n=22) found the community POC model acceptable, provided that privacy could be ensured because the service was convenient and delivered close to home. CONCLUSION: We demonstrate the acceptability, appropriateness, and feasibility of implementing the community POC model in Zambia, while identifying potential challenges related to client privacy and platform field operations. The community POC model may represent a promising strategy to further facilitate active HIV case finding and linkage to ART for children with undiagnosed HIV infection in the community.

Geospatial Transmission Hotspots of Recent HIV Infection - Malawi, October 2019-March 2020.

Persons infected with HIV are more likely to transmit the virus during the early stages (acute and recent) of infection, when viral load is elevated and opportunities to implement risk reduction are limited because persons are typically unaware of their status (1,2). Identifying recent HIV infections (acquired within the preceding 12 months)* is critical to understanding the factors and geographic areas associated with transmission to strengthen program intervention, including treatment and prevention (2). During June 2019, a novel recent infection surveillance initiative was integrated into routine HIV testing services in Malawi, a landlocked country in southeastern Africa with one of the world's highest prevalences of HIV infection.† The objectives of this initiative were to collect data on new HIV diagnoses, characterize the epidemic, and guide public health response (2). New HIV diagnoses were classified as recent infections based on a testing algorithm that included results from the rapid test for recent infection (RTRI)§ and HIV viral load testing (3,4). Among 9,168 persons aged ≥15 years with a new HIV diagnosis who received testing across 103 facilities during October 2019-March 2020, a total of 304 (3.3%) were classified as having a recent infection. Higher proportions of recent infections were detected among females, persons aged <30 years, and clients at maternal and child health and youth clinics. Using a software application that analyzes clustering in spatially referenced data, transmission hotspots were identified with rates of recent infection that were significantly higher than expected. These near real-time HIV surveillance data highlighted locations across Malawi, allowing HIV program stakeholders to assess program gaps and improve access to HIV testing, prevention, and treatment services. Hotspot investigation information could be used to tailor HIV testing, prevention, and treatment to ultimately interrupt transmission.

Sex Differences in HIV Testing - 20 PEPFAR-Supported Sub-Saharan African Countries, 2019.

Despite progress toward controlling the human immunodeficiency virus (HIV) epidemic, testing gaps remain, particularly among men and young persons in sub-Saharan Africa (1). This observational study used routinely collected programmatic data from 20 African countries reported to the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) from October 2018 to September 2019 to assess HIV testing coverage and case finding among adults (defined as persons aged ≥15 years). Indicators included number of HIV tests conducted, number of HIV-positive test results, and percentage positivity rate. Overall, the majority of countries reported higher HIV case finding among women than among men. However, a slightly higher percentage positivity was recorded among men (4.7%) than among women (4.1%). Provider-initiated counseling and testing (PITC) in health facilities identified approximately two thirds of all new cases, but index testing had the highest percentage positivity in all countries among both sexes. Yields from voluntary counseling and testing (VCT) and mobile testing varied by sex and by country. These findings highlight the need to identify and implement the most efficient strategies for HIV case finding in these countries to close coverage gaps. Strategies might need to be tailored for men who remain underrepresented in the majority of HIV testing programs.

Birth Testing for Infant HIV Diagnosis in Eswatini: Implementation Experience and Uptake Among Women Living With HIV in Manzini Region.

INTRODUCTION: HIV testing at birth of HIV-exposed infants (HEIs) may improve the identification of infants infected with HIV in utero and accelerate antiretroviral treatment (ART) initiation. METHODS: ICAP at Columbia University supported implementation of a national pilot of HIV testing at birth (0-7 days) in Eswatini at 2 maternity facilities. Dried blood spot (DBS) samples from neonates of women living with HIV (WLHIV) were collected and processed at the National Molecular Reference Laboratory using polymerase chain reaction (PCR). Mothers received birth test results at community health clinics. We report data on HIV birth testing uptake and outcomes for HIV-positive infants from the initial intensive phase (October 2017-March 2018) and routine support phase (April-December 2018). RESULTS: During the initial intensive pilot phase, 1669 WLHIV delivered 1697 live-born HEI at 2 health facilities and 1480 (90.3%) HEI received birth testing. During the routine support phase, 2546 WLHIV delivered and 2277 (93.5%) HEI received birth testing. Overall October 2017-December 2018, 22 (0.6%) infants of 3757 receiving birth testing had a positive PCR test, 15 (68.2%) of whom were successfully traced and linked for confirmatory testing (2 infants were reported by caregivers to have negative follow-up HIV tests). Median time from birth test to receipt of results by the caregiver was 13 days (range: 8-23). Twelve (60.0%) of 20 infants confirmed to be HIV-positive started ART at median age of 17.5 days (12-43). One mother of an HIV-positive infant who was successfully traced refused ART following linkage to care and another child died after ART initiation. Three infants (15.0%) had died by the time their mothers were reached and 4 (15.0%) infants were never located. CONCLUSION: This pilot of universal birth testing in Eswatini demonstrates the feasibility of using a standard of care approach in a low resource and high burden setting. We document high uptake of testing for newborns among HIV-positive mothers and very few infants were found to be infected through birth testing.

Beyond Early Infant Diagnosis: Changing the Approach to HIV-Exposed Infants.

Despite dramatic global progress with implementing prevention of mother-to-child HIV transmission (PMTCT) programs, there were 160,000 new pediatric HIV infections in 2016. More than 50% of infant HIV infections now occur in the postpartum period, reflecting the relatively high coverage of interventions in the antenatal period and the need for greater attention to the breastfeeding mother and her HIV-exposed infant (HEI). Early diagnosis and treatment are critical to prevent morbidity and mortality in HIV-infected children; however, early infant HIV testing rates remain low in most high HIV-burden countries. Furthermore, systematic retention and follow-up of HEI in the postpartum period and ascertainment of final HIV status remain major program gaps. Despite multiple calls to action to improve infant HIV testing rates, progress has been marginal due to a lack of focus on the critical health care needs of HEI coupled with health system barriers that result in fragmented services for HIV-infected mothers and their families. In this paper, we describe the available evidence on the health outcomes of HEI, define a comprehensive care package for HEI that extends beyond early HIV testing, and describe successful examples of integrated services for HEI.

Triple therapy of vincristine, bleomycin and etoposide for children with Kaposi sarcoma: Results of a study in Malawian children.

BACKGROUND: Kaposi sarcoma (KS) is the most common paediatric cancer in human immunodeficiency virus (HIV) endemic countries of sub-Saharan Africa, but there is little research on management and outcomes. METHODS: Children with KS at Queen Elizabeth Central Hospital, Blantyre, Malawi treated between August 2012 and March 2015 with six courses of vincristine, bleomycin and etoposide combination chemotherapy, including antiretroviral therapy (ART) if HIV infected, were studied and outcomes compared with previously reported results. FINDINGS: Fifty-six children were included; 38 (68%) were male; and 48 (86%) were HIV positive, of whom 36 (77%) were on ART at diagnosis. Median age at diagnosis was 8 years (interquartile range [IQR] 3-12) and median follow-up was 16.9 months (IQR 3.4-36.4). Quality of life improved in 45 (80%) children; the median Lansky Score increased from 80% pre-treatment to 100% post-treatment. Eighteen (32%) children had complete response to treatment. At 12 months, overall survival was 71% (95% confidence interval [CI] 56-82) and event-free survival (event = death, loss to follow-up or relapse) was 50% (95% CI 36-63). At 1 year, the risk of loss to follow-up was 13.4%. In a previous, same-site, randomized controlled study of vincristine monotherapy, vincristine and bleomycin, or oral etoposide, oral etoposide monotherapy had the best outcome with survival at 12 month of 66% (95% CI 46-80) and event-free survival of 52% (95% CI 33-68); however, loss to follow-up was not reported. CONCLUSION: Overall survival, event-free survival and quality of life appear to have improved with this three-agent combination chemotherapy; however larger, randomized studies are needed to determine optimal management.

Overcoming Health System Challenges for Women and Children Living With HIV Through the Global Plan.

To meet the ambitious targets set by the Global Plan Towards the Elimination of New HIV Infections Among Children by 2015 and Keeping Their Mothers Alive (Global Plan), the initial 22 priority countries quickly developed innovative approaches for overcoming long-standing health systems challenges and providing HIV testing and treatment to pregnant and breastfeeding women and their infants. The Global Plan spurred programs for prevention of mother-to-child HIV transmission to integrate HIV-related care and treatment into broader maternal, newborn, and child health services; expand the effectiveness of the health workforce through task sharing; extend health services into communities; strengthen supply chain and commodity management systems; reduce diagnostic and laboratory hurdles; and strengthen strategic supervision and mentorship. The article reviews the ongoing challenges for prevention of mother-to-child HIV transmission programs as they continue to strive for elimination of vertical transmission of HIV infection in the post-Global Plan era. Although progress has been rapid, health systems still face important challenges, particularly follow-up and diagnosis of HIV-exposed infants, continuity of care, and the promotion of services that are respectful and client centered.

Early Diagnosis of HIV Infection in Infants - One Caribbean and Six Sub-Saharan African Countries, 2011-2015.

Pediatric human immunodeficiency virus (HIV) infection remains an important public health issue in resource-limited settings. In 2015, 1.4 million children aged <15 years were estimated to be living with HIV (including 170,000 infants born in 2015), with the vast majority living in sub-Saharan Africa (1). In 2014, 150,000 children died from HIV-related causes worldwide (2). Access to timely HIV diagnosis and treatment for HIV-infected infants reduces HIV-associated mortality, which is approximately 50% by age 2 years without treatment (3). Since 2011, the annual number of HIV-infected children has declined by 50%. Despite this gain, in 2014, only 42% of HIV-exposed infants received a diagnostic test for HIV (2), and in 2015, only 51% of children living with HIV received antiretroviral therapy (1). Access to services for early infant diagnosis of HIV (which includes access to testing for HIV-exposed infants and clinical diagnosis of HIV-infected infants) is critical for reducing HIV-associated mortality in children aged <15 years. Using data collected from seven countries supported by the U.S. President's Emergency Plan for AIDS Relief (PEPFAR), progress in the provision of HIV testing services for early infant diagnosis was assessed. During 2011-2015, the total number of HIV diagnostic tests performed among HIV-exposed infants within 6 weeks after birth (tests for early infant diagnosis of HIV), as recommended by the World Health Organization (WHO) increased in all seven countries (Cote d'Ivoire, the Democratic Republic of the Congo, Haiti, Malawi, South Africa, Uganda, and Zambia); however, in 2015, the rate of testing for early infant diagnosis among HIV-exposed infants was <50% in five countries. HIV positivity among those tested declined in all seven countries, with three countries (Cote d'Ivoire, the Democratic Republic of the Congo, and Uganda) reporting >50% decline. The most common challenges for access to testing for early infant diagnosis included difficulties in specimen transport, long turnaround time between specimen collection and receipt of results, and limitations in supply chain management. Further reductions in HIV mortality in children can be achieved through continued expansion and improvement of services for early infant diagnosis in PEPFAR-supported countries, including initiatives targeted to reach HIV-exposed infants, ensure access to programs for early infant diagnosis of HIV, and facilitate prompt linkage to treatment for children diagnosed with HIV infection.

Characteristics and trends in publication of scientific papers presented at the European Congress of Radiology: a comparison between 2000 and 2010.

OBJECTIVE: To determine journal publication rates of scientific papers presented orally at the European Congress of Radiology (ECR) 2010, with comparison of country data to ECR 2000. METHODS: All oral presentations from ECR 2010 were evaluated for publication between 2010 and 2014 using the MEDLINE database. Countries, collaborations, subspecialties, modalities and study design were ranked by publication percentage. Chi-square tests were used to compare publication percentages for each category of variables. Hazard ratios (HR) were calculated for each country relative to the host nation, Austria. ECR 2010 country statistics were compared with analogous data from ECR 2000. RESULTS: In total, 360/840 abstracts were subsequently published (43 %). The author's country of origin (p = 0.02), subspecialty (p = 0.02) and study design (p = 0.001) were significantly associated with subsequent publication. Switzerland, the Netherlands, France and Germany were among the top six countries by publication percentage in 2000 and 2010. In 2010, Switzerland had the highest publication rate (62 %) and HR in comparison to Austria (HR 2.62 [1.31-5.25], p = 0.01). Three Asian nations increased relative publication rates over the 10-year period. CONCLUSION: Several European nations consistently convert relatively high percentages of oral abstracts at ECR into publications, and the influence of Asian countries is increasing. MAIN MESSAGES: • Certain European nations consistently publish high percentages of orally presented abstracts at ECR. • The influence of several Asian countries on ECR is increasing. • Country, subspecialty and study design are significantly associated with journal publication. • Authors collaborating internationally have the highest publication rates and mean impact factors. • Among all modalities, PET-CT, MRI and CT have the highest publication percentages.

Follow-up of infants diagnosed with HIV - Early Infant Diagnosis Program, Francistown, Botswana, 2005-2012.

The 2011 prevalence of human immunodeficiency virus (HIV) among pregnant women in Botswana was 30.4%. High coverage rates of HIV testing and antiretroviral prophylaxis have reduced the rate of mother-to-child transmission of HIV in Botswana from as high as 40% with no prophylaxis to <4% in 2011. In June 2005, the national Early Infant Diagnosis (EID) Program began testing HIV-exposed infants (i.e., those born to HIV-infected mothers) for HIV using polymerase chain reaction (PCR) at 6 weeks postpartum. During 2005-2012, follow-up of all HIV-infected infants diagnosed in all 13 postnatal care facilities in Francistown, Botswana, was conducted to ascertain patient outcomes. A total of 202 infants were diagnosed with HIV. As of September 2013, 82 (41%) children were alive and on antiretroviral therapy (ART), 79 (39%) had died, and 41 (20%) were either lost to follow-up, had transferred, or their mothers declined ART. Despite success in preventing mother-to-child transmission in Botswana, results of the EID program highlight the need for early diagnosis of HIV-infected infants, prompt initiation of ART, and retention in care.

Improved access to early infant diagnosis is a critical part of a child-centric prevention of mother-to-child transmission agenda.

BACKGROUND: Prevention-of-mother-to-child-transmission (PMTCT) programs have made it possible to achieve dramatic reductions in the rate of vertical HIV transmission. However, high attrition, particularly after delivery, has limited the impact of these interventions for HIV-exposed infants who remain at risk through the end of breastfeeding. DESIGN AND METHODS: A review of current literature on early infant diagnosis (EID) testing and country experience in low-and middle-income countries. RESULTS: While PMTCT programs report reduced rates of infection among infants tested at 2 months of age, too few services are focused on retention of HIV-exposed infants in care. An unacceptably large proportion of HIV-exposed and HIV-infected infants remain unidentified. While the complexities of EID have been simplified with the development of optimized commodities and tools to improve service delivery, the inaccessibility and inadequate uptake of EID services has resulted in lag of care for the millions of HIV-exposed infants who remain unidentified. Coverage of EID testing remains low and there are many HIV- infected infants or at risk of infection who may not enter the health system through PMTCT programs. Waiting for HIV-infected children to present sick is not an adequate strategy for identifying and linking infants to treatment. Several interventions suggest a potential to expand access to EID testing, while more aggressive testing strategies may ensure children can be captured at any point of contact with the health system. CONCLUSIONS: Programs focused on preventing vertical transmission need to increase their commitment to child-centric interventions and broaden their measure of success to reflect infants who test negative at the end of the exposure period. This paper argues that EID is a key strategy to retaining HIV-exposed infants through the end of the exposure period, as it provides an opportunity to offer early clinical care and continuous follow up. It is imperative that maternal and child survival programs become sensitized to the urgency of early identification of HIV in infants and their retention in care.

Deaths of cyclists in London: trends from 1992 to 2006.

BACKGROUND: Cycling is an increasingly important mode of transport for environmental and health reasons. Cycling fatalities in London were previously investigated in 1994 using routinely collected data. Since then, there have been shifts in the modes of transport used, and in transport policies. We sought to replicate the previous work using data on cyclist deaths in London between 1992 and 2006, specifically investigating whether heavy goods vehicles continued to pose a threat. METHODS: Observational study based on analysis of time series of police road casualties data, 1992 to 2006, in London, UK. The main outcome measures were cyclists killed in road traffic collisions. Poisson regression and chi-squared test for homogeneity were used to assess time effects. Travel flow data was then used to estimate annual fatality rates per 100,000 cyclists per kilometre. RESULTS: From 1992 to 2006 there was a mean of 16 cycling fatalities per year (range 8-21). 146 deaths (60%) were in inner London and 96 in outer London. There was no evidence for a decline over time (p = 0.7) other than a pronounced dip in 2004 when there were 8 fatalities. Freight vehicles were involved in 103 of 242 (43%) of all incidents and the vehicle was making a left turn in over half of these (53%). The fatality rate ranged from 20.5 deaths in 1992 to 11.1 deaths in 2006 per 100,000 estimated cyclists per kilometre (rate ratio 0.54, 95% confidence interval 0.28 to 1.03). CONCLUSIONS: There is little evidence fatality rates have fallen. Freight vehicles over 3.5 tonnes continue to present a disproportionate threat; they should be removed from urban roads and more appropriate means of delivery of essential goods found.

What young African American women want in a health care provider.

The Institute of Medicine's report on racial and ethnic disparities in health care encourages enhancing patient-provider relationships by building trust. We explored factors important to 19- to 24-year-old African American women (N = 40) in choosing a health care provider. Eight focus groups were held in seven Ohio counties. Discussion was aided by photographs of client-provider interactions: two African American and two White providers (man or woman in each); in similar settings, attire, and pose; with a young African American woman client. Participants commented on what was happening in the photographs, how the woman felt, and their perceptions of each provider. Fongwa's Quality of Care model guided analysis. Women providers were favored; race was not of primary concern. Provider proximity, perceived interest, and understandability were persistent preferences. Trust, awareness of body language, interest in client, and conveying information clearly are critical for providers caring for young African American women.

Blood pressure in the neonate: three non-invasive oscillometric pressure monitors compared with invasively measured blood pressure.

AIM: To compare blood pressure in neonates obtained from three different oscillometer blood pressure monitors (Dinamap, Criticare, Hewlett-Packard) with arterial blood pressure (Hewlett-Packard' invasive unit). STUDY DESIGN: A total of 32 randomized, non-invasive blood pressure series, each consisting of three measurements from each monitor, were obtained from 20 neonates (birthweight 531-4660 g). Each measurement was compared with the invasive pressure. RESULTS: Two factors appear to have a systematic effect on the difference between oscillometric and invasive pressure (the measurement deviance): the size of the infant, e.g., the arm circumference, and the monitor system. For small infants, the non-invasively measured value tends to be too high. The deviance is partly reversed for larger infants (dependency on size significant for mean and diastolic pressure, p < 0.001). The difference between monitor systems is clearly significant (p < 0.001). Hewlett-Packard gives the lowest pressure values for all pressures. Thus, Criticare and Dinamap tended to show values too high in the smallest infants, while Hewlett-Packard tended to give values too low in larger infants. Birthweight, present weight and arm circumference affected measurement deviance approximately equally strongly, while factors such as the infant's sex, need of breath support and umbilical or radial arterial line were non-significant. CONCLUSIONS: Blood pressure should preferably be measured invasively in severely ill neonates and preterm infants, being aware of pitfalls with measurements using different oscillometer monitors and the size/arm circumference of the infant.

What are the needs of asylum seekers attending an STI clinic and are they significantly different from those of British patients?

To elicit the needs of asylum seekers attending the Royal Hallamshire genitourinary medicine clinic for the first time in 2002 and whether these differed from British patients, a search of patient records for 2002 identified 43 asylum seekers (21 female, 22 male) who were paired with 43 British patients matched by age and sex (mean age 27.9, range 15-56). The needs of the patients were ascertained by retrieving answers to predetermined questions from the paper records. Asylum seekers had 166 appointments while British patients had 113 (P = 0.091) and 21 DNAs (did not attend appointment), compared with seven British DNAs (P = 0.071). Twenty-eight asylum seekers and no British patients needed an interpreter (P < 0.01). Five of the 18 eligible asylum seeker females had an up-to-date smear compared with 13 British females (P = 0.008). Nineteen asylum seekers reported sexual violence compared with none of the British patients (P < 0.011); 15 of these asylum seekers were receiving/had requested counselling. There was no significant difference in the numbers of pregnant women, commercial sex workers and intravenous drug users, and patients reporting a previous history of sexually transmitted infection. There are some differences between the needs of asylum seekers and British patients; the most noticeable are the use of interpreters, the reporting of sexual violence, the need for counselling and the number of women without up-to-date smears. A larger study may highlight more differences.
