    MANDATORY HIV TESTING IN PREGNANCY: IS THERE EVER A TIME?

    DEVELOPING WORLD BIOETHICS, Issue 1 2008
    RUSSELL ARMSTRONG
    ABSTRACT Despite recent advances in ways to prevent transmission of HIV from a mother to her child during pregnancy, infants continue to be born and become infected with HIV, particularly in southern Africa where HIV prevalence is the highest in the world. In this region, emphasis has shifted from voluntary HIV counselling and testing to routine testing of women during pregnancy. There have also been proposals for mandatory testing. Could mandatory testing ever be an option, even in high-prevalence settings? Many previous examinations of mandatory testing have dealt with it in the context of low HIV prevalence and a well-resourced health care system. In this discussion, different assumptions are made. Within this context, where mandatory testing may be a strategy of last resort, the objections to it are reviewed. Special attention is paid in the discussion to the entrenched vulnerability of women in much of southern Africa and how this contributes to both HIV prevalence and ongoing challenges for preventing HIV transmission during pregnancy. While mandatory testing is ethically plausible, particularly when coupled with guaranteed access to treatment and care, the discussion argues that the moment to employ this strategy has not yet come. Many barriers remain for pregnant women in terms of access to testing, treatment and care, most acutely in the southern African setting, despite the presence of national and international human rights instruments aimed at empowering women and removing such barriers. While this situation persists, mandatory HIV testing during pregnancy cannot be justified. [source]

    Human papillomavirus prevalence and cytopathology correlation in young Ugandan women using a low-cost liquid-based pap preparation

    DIAGNOSTIC CYTOPATHOLOGY, Issue 8 2010
    Janis M. Taube M.D.
    Abstract Screening for HPV-driven cervical dysplasia and neoplasia is a significant public health concern in the developing world. The purpose of this study was to use a manual, low-cost liquid-based Pap preparation to determine HPV prevalence in HIV-positive and HIV-negative young women in Kampala, Uganda and to correlate cervical cytopathology with HPV-DNA genotype. About 196 post-partum women aged 18,30 years underwent rapid HIV testing and pelvic examination. Liquid-based cervical cytology samples were processed using a low-cost manual technique. A DNA collection device was used to collect specimens for HPV genotyping. HIV and HPV prevalence was 18 and 64%, respectively. Overall, 49% of women were infected with a high-risk HPV genotype. The most common high-risk HPV genotypes were 16 (8.2%), 33 (7.7%), 35 (6.6%), 45 (5.1%), and 58 (5.1%). The prevalence of HPV 18 was 3.6%. HIV-positive women had an HPV prevalence of 86% compared to 59% in HIV-negative women (P = 0.003). The prevalence of HPV 16/18 did not differ by HIV status. HIV-positive women were infected with a significantly greater number of HPV genotypes compared to HIV-negative women. By multivariate analysis, the main risk factor for HPV infection was coinfection with HIV. HIV-positive women were four times more likely to have abnormal cytology than HIV-negative women (43% vs. 11.6%, P < 0.001). These data highlight that HIV infection is a strong risk factor for HPV infection and resultant abnormal cervical cytology. Notably, the manual low-cost liquid-based Pap preparation is practical in this setting and offers an alternate method for local studies of HPV vaccine efficacy. Diagn.

    Interventions with injection drug users in Ukraine

    ADDICTION, Issue 11 2009
    Robert E. Booth
    ABSTRACT Aims To assess the effectiveness of a brief human immunodeficiency virus (HIV) testing and counseling intervention compared to a more time-consuming and expensive street-based intervention with injection drug users (IDUs). Design Cross-over experimental design in which 900 IDUs were recruited, followed by a ,wash-out' period with no recruitment, a reversal of intervention assignment areas and an additional recruitment of 900 IDUs with baseline and 6-month follow-up assessments. Setting Kiev, Odessa and Makeevka/Donesk Ukraine. Participants A total of 1798 IDUs. Measurements HIV testing and audio computer-assisted self-interview (ACASI) data on socio-demographics, drug use and injection and sex-related risk behaviors. Findings Participants in both conditions reduced their injection and sex risks significantly; however, there was little difference in outcomes between conditions. IDUs who knew they were HIV-infected at baseline were significantly more likely to practice safe sex than those unaware or HIV-negative; those who first learned that they were infected at baseline changed their safe sex practices significantly more than those who already knew that they were infected at baseline and those who were HIV-negative. Younger IDUs and those injecting for a shorter period of time reported higher injection and sex risk behaviors following interventions. Conclusions Awareness of HIV infection by street-recruited drug injectors is associated with reduced sex risks. Additional interventions are required for younger IDUs and those injecting for shorter periods of time. [source]

    Factors associated with incarceration and incident human immunodeficiency virus (HIV) infection among injection drug users participating in an HIV vaccine trial in Bangkok, Thailand, 1999,2003

    ADDICTION, Issue 2 2009

    ABSTRACT Aims To determine if incarceration was associated with human immunodeficiency virus (HIV) infection and identify risk factors for incarceration among injection drug users (IDUs) participating in an HIV vaccine trial in Bangkok. Design The AIDSVAX B/E HIV vaccine trial was a randomized, double-blind, placebo-controlled study. A proportional hazards model was used to evaluate demographic characteristics, risk behavior and incarceration as predictors of HIV infection and generalized estimation equation logistic regression analysis to investigate demographic characteristics and risk behaviors for predictors of incarceration. Setting The trial was conducted in Bangkok Metropolitan Administration drug-treatment clinics, 1999,2003. Participants A total of 2546 HIV-uninfected IDUs enrolled in the trial. Measurements HIV testing was performed and an interviewer-administered questionnaire was used to assess risk behavior and incarceration at baseline and every 6 months for a total of 36 months. Findings HIV incidence was 3.4 per 100 person-years [95% confidence interval (CI), 3.0,3.9] and did not differ among vaccine and placebo recipients. In multivariable analysis, being in jail (P < 0.04), injecting (P < 0.0001), injecting daily (P < 0.0001) and sharing needles (P = 0.02) were associated with HIV infection and methadone maintenance was protective (P = 0.0006). Predictors of incarceration in multivariable analysis included: male sex (P = 0.04), younger age (P < 0.0001), less education (P = 0.001) and being in jail (P < 0.0001) or prison (P < 0.0001) before enrollment. Conclusions Among IDUs in the AIDSVAX B/E trial, incarceration in jail was associated with incident HIV infection. IDUs in Thailand remain at high risk of HIV infection and additional prevention tools are needed urgently. HIV prevention services, including methadone, should be made available to IDUs. [source]

    Preventive Care in the Emergency Department: Should Emergency Departments Conduct Routine HIV Screening?

    ACADEMIC EMERGENCY MEDICINE, Issue 3 2003
    A Systematic Review
    Abstract Objective: To perform a systematic review of the emergency medicine literature to assess the appropriateness of offering routine HIV screening to patients in the emergency department (ED). Methods: The systematic review was conducted with the aid of a structured template, a companion explanatory guide, and a grading and methodological scoring system based on published criteria for critical appraisal. Two reviewers conducted independent searches using OvidR, PubMed, MD Consult, and Grateful Med. Relevant abstracts were reviewed; those most pertinent to the stated objective were selected for complete evaluation using the structured template. Results: Fifty-two relevant abstracts were reviewed; of these, nine were selected for detailed evaluation. Seven ED-based prospective cross-sectional seroprevalence studies found HIV rates of 2,17%. Highest rates of infection were seen among patients with behavioral risks such as male homosexual activity and intravenous drug use. Two studies demonstrated feasibility of both standard and rapid HIV testing in the ED, with more than half of the patients approached consenting to testing by either method, consistent with voluntary testing acceptance rates described in other settings. Several cost,benefit analyses lend indirect support for HIV screening in the ED. Conclusions: Multiple ED-based studies meeting the Centers for Disease Control and Prevention Guideline threshold to recommend routine screening, in conjunction with limited feasibility trials and extrapolation from cost,benefit studies, provide evidence to recommend that EDs offer HIV screening to high-risk patients (i.e., those with identifiable risk factors) or high-risk populations (i.e., those where HIV seroprevelance is at least 1%).

    Emergency Department Staff Satisfaction With Rapid Human Immunodeficiency Virus Testing

    ACADEMIC EMERGENCY MEDICINE, Issue 5 2010
    Aparajita Sohoni MD
    Abstract Objectives:, The authors sought to determine staff satisfaction with an emergency department (ED) rapid human immunodeficiency virus (HIV) testing program. Methods:, A survey was conducted in an urban ED that has provided rapid HIV testing (routine screening and physician-initiated testing) since August 2007. From May 1, 2008, to August 31, 2008, the survey was administered to all ED staff involved with HIV testing. The primary outcome was satisfaction, and secondary outcomes were the staff attitudes toward the program. Results:, Surveys were administered to 215 of the 217 staff members, and 207 surveys were returned (96% response rate); 201 surveys had complete data available for analysis. The response rate by staffing type was as follows: physicians 64/64 (100%), nurses 124/134 (93%), and registration staff 16/19 (84%). The majority of ED staff (99%; 95% confidence interval [CI] = 95% to 100%) were satisfied with the HIV testing program. Physicians, however, rated the program more favorably than nurses or registration staff. Most staff members agreed that HIV testing improved overall care (93%; 95% CI = 89% to 96%) and felt that HIV testing did not interfere with their ability to provide care (82%; 95% CI = 76% to 87%). The majority of staff perceived that patients were satisfied with the procedures for obtaining consent (73%; 95% CI = 67% to 79%) and with the way HIV testing was performed (83%; 95% CI = 77% to 87%). Conclusions:, Emergency department staff satisfaction and overall attitudes with the HIV testing program is high. ED staff does not appear to be a barrier to program implementation.

    Determinants of late HIV diagnosis among different transmission groups in Finland from 1985 to 2005

    HIV MEDICINE, Issue 6 2010
    PS Kivelä
    Objectives To study determinants of late HIV diagnosis in a low-HIV-prevalence (<0.1%) country where HIV spread among men who have sex with men (MSM) and heterosexuals in the 1980s, and among injecting drug users (IDUs) in the late 1990s. Methods Newly diagnosed HIV cases referred to the Helsinki University Central Hospital between 1985 and 2005 were reviewed to identify determinants of late HIV diagnosis, defined as diagnosis when the first CD4 count was <200 cells/,L, or when AIDS occurred within 3 months of HIV diagnosis. Determinants of late diagnosis were analysed using multivariate logistic regression. Results Among 934 HIV cases, 211 (23%) were diagnosed late. In the first 4-year interval of each sub-epidemic (1985,1989 for MSM and heterosexuals, 1998,2001 for IDUs), rates of late HIV diagnosis were 13%, 18% and 6%, respectively, but increased thereafter to 29%, 27% and 37%. Late diagnosis was associated with non-Finnish ethnicity, older age, male gender, lack of earlier HIV testing, diagnosis at health care settings and later stage of the sub-epidemic. Conclusions The lower rate of late diagnosis in the first 4-year interval of each HIV sub-epidemic suggests that the early stages of the HIV epidemic in Finland were detected early. This factor may have contributed to the low prevalence of HIV infection in Finland. The stage and age of the epidemic should be taken into account when interpreting the data on late HIV diagnosis, especially in cross-country comparisons. [source]

    Optimal HIV testing and earlier care: the way forward in Europe

    HIV MEDICINE, Issue 2008
    T Coenen
    The articles in this supplement were developed from a recent pan-European conference entitled ,HIV in Europe 2007: Working together for optimal testing and earlier care', which took place on 26,27 November in Brussels, Belgium. The conference, organized by a multidisciplinary group of experts representing advocacy, clinical and policy areas of the HIV field, was convened in an effort to gain a common understanding on the role of HIV testing and counselling in optimizing diagnosis and the need for earlier care. Key topics discussed at the conference and described in the following articles include: current barriers to HIV testing across Europe, trends in the epidemiology of HIV in the region, problems associated with undiagnosed infection and the psychosocial barriers impacting on testing. The supplement also provides a summary of the World Health Organization's recommendations for HIV testing in Europe and an outline of an indicator disease-guided approach to HIV testing proposed by a committee of experts from the European AIDS Clinical Society (EACS). We hope that consideration of the issues discussed in this supplement will help to shift the HIV field closer towards our ultimate goal: provision of optimal HIV testing and earlier care across the whole of the European region.

    Prevalence of hepatitis C in an ethnically diverse HIV-1-infected cohort in south London

    HIV MEDICINE, Issue 3 2005
    AH Mohsen
    Objectives There is limited information on the prevalence of and risk factors for hepatitis C virus (HCV) infection among HIV-1-infected patients in the UK. Our objective was to determine the prevalence of HCV infection among an ethnically diverse cohort of HIV-infected patients in south London, and to extrapolate from these data the number of co-infected patients in the UK. Methods A total of 1017 HIV-1-infected patients who had attended King's College Hospital HIV clinic between September 2000 and August 2002 were screened for HCV antibody using a commercial enzyme-linked immunosorbent assay (ELISA). Positive results were confirmed by polymerase chain reaction (PCR) or recombinant immunoblot assay. Demographic, clinical and laboratory data were obtained from the local computerized database and medical records. We applied our HCV prevalence rates in the different HIV transmission groups to the estimated number of HIV-infected persons in these groups in the UK, to obtain a national estimate of the level of HIV-HCV co-infection. Results Of the 1017 HIV-1-infected patients, 407 (40%) were white men, 158 (15.5%) were black African men, 268 (26.3%) were black African women, and 61 (6%) and 26 (2.6%) were black Caribbean men and women, respectively. Heterosexual exposure was the most common route of HIV acquisition (53.5%), followed by men having sex with men (36.9%), and current or previous injecting drug use (IDU) (7.2%). The overall prevalence of HCV co-infection was 90/1017 (8.9%), but this varied substantially according to route of transmission, from 82.2% among those with a history of IDU (which accounted for 67% of all HCV infections), to 31.8% in those who had received blood products, to 3.5% and 1.8% in those with homosexually and heterosexually acquired infection, respectively. Multivariate logistic regression analysis identified several independent risk factors for HCV infection: a history of IDU [odds ratio (OR)=107.2; 95% confidence interval (CI)=38.5,298.4], having received blood products (OR=16.5; 95% CI=5.1,53.7), and either being from a white ethnic group (OR=4.3; 95% CI=1.5,12.0) or being born in Southern Europe (OR=6.7; 95% CI=1.5,30.7). Based on the 35 473 known HIV-1-infected persons in the UK and the 10 997 estimated to be unaware of their status, we projected that there are at least 4136 HIV-HCV co-infected individuals in the UK and 979 who are unaware of their status. Conclusions Overall, 9% of our cohort was HIV-HCV co-infected. The prevalence was highest among intravenous drug users (82%), who accounted for most of our HCV cases, and lowest among heterosexual men and women from sub-Saharan Africa and the Caribbean [< 2%]. Our estimate that a significant number of co-infected persons may be unaware of their HIV and HCV status, highlights an urgent need to increase the uptake of HCV and HIV testing, particularly among injecting drug users, to reduce the risk of onward transmission.

    A systematic review of counselling for HIV testing of pregnant women

    JOURNAL OF CLINICAL NURSING, Issue 13 2009
    Karin S Minnie
    Background., Evidence-based strategies have made it possible to limit mother-to-child transmission of the HI-virus to a large extent and enable HIV-positive women to stay healthy for longer, provided their HIV status is known. Although voluntary counselling and testing for HIV is part of routine antenatal care in South Africa, the uptake of testing varies and a large number of pregnant women's HIV status is not known at the time of birth. Aim., The aim of the study was to establish research evidence regarding factors influencing counselling for HIV testing during pregnancy by means of systematic review, forming part of a larger study using a variety of evidence to develop best practice guidelines. Design., Systematic review. Methods., The question steering the review was: ,What factors influence counselling for HIV testing during pregnancy?'. A multi-stage search of relevant research studies was undertaken using a variety of sources. A total of 33 studies were retrieved and critically appraised. Data were extracted from the studies and assessed according to its applicability in the South African context. Results., The results are presented according to the following themes: effects of counselling, quality of counselling, group vs. individual counselling, ways of offering HIV testing, rapid testing, counselling and testing during labour, couple counselling and testing, counsellor and organisational factors. Conclusions., According to research evidence, factors such as whether counselling is presented in a group or individually, different ways to present HIV testing as well as counsellor and organisational factors can influence counselling for HIV testing during pregnancy. When developing best practice guidelines for settings very dissimilar from where the research was done, research evidence must be contextualised. Relevance to clinical practice., Implementation of the best practice guidelines may lead to the increased uptake of HIV testing in pregnancy in developing countries like South Africa and thus to an increase in the number of women whose status is known when their babies are born.

    Influences on HIV testing among young African-American men who have sex with men and the moderating effect of the geographic setting

    JOURNAL OF COMMUNITY PSYCHOLOGY, Issue 1 2004
    Andrew J. Mashburn
    This study examined the influence of demographic characteristics, risk behaviors, knowledge, and psychosocial variables on HIV testing among a sample (n = 551) of young African-American men who have sex with men (MSM) from three cities,Atlanta (n = 241), Birmingham (n = 174), and Chicago (n = 136). Among the entire sample of young men, age, knowledge of HIV treatments, knowledge of a comfortable place for an HIV test, and social support were related positively to rates of HIV testing. Furthermore, men who had sex with both main male partner(s) and non-main male partner(s) during the past year had significantly higher rates of HIV testing than men who had non-main male partner(s) only. Geographic setting moderated the effect on HIV testing behavior. In particular, social support, peer norms about condom use, and knowledge of HIV treatments were not associated with HIV testing in Atlanta, but were associated positively with HIV testing in either Birmingham, Chicago, or both. The strongest influence on HIV testing across all three settings was knowledge of a comfortable place for an HIV test. Implications of these findings for designing interventions to increase HIV testing are discussed. © 2004 Wiley Periodicals, Inc. J Comm Psychol 32: 45,60, 2004. [source]

    Failure to confirm HIV infection in two end-stage HIV/AIDS patients using a popular commercial line immunoassay

    JOURNAL OF MEDICAL VIROLOGY, Issue 9 2008
    Julian W. Tang
    Abstract Immunoassays using either viral lysate (Western blot) or recombinant/synthetic antigen (immunoblot) for anti-HIV capture are still the preferred method to confirm HIV infection. Two cases of HIV-1-infected patients presented with acquired immunodeficiency syndrome (AIDS)-defining illnesses. Laboratory tests were performed using multiple commercial HIV test kits on multiple sera from both patients over several weeks. Both patients were strongly positive on the anti-HIV/p24 antigen combined screening assay. Yet, HIV-1 infection could not be confirmed using a popular commercial immunoassay. Eventually, HIV infection was confirmed using an alternative commercial Western blot assay as well as an HIV quantitative PCR test. In laboratories without nucleic acid testing (NAT) for HIV, indeterminate results may delay confirmation of HIV infection, if commercial line immunoassays alone are available. Some end-stage HIV/AIDS patients may not produce antibodies to specific HIV antigens and may therefore give indeterminant or negative results on some immunoassays, depending on the type of antigen used. This report highlights the utility of having NAT available when diagnosing difficult cases of HIV infection, especially in light of the recent Centers for Disease Control and Prevention move towards more universal, routine, HIV testing.

    Hepatitis C virus seropositivity in a South African Cohort of HIV co-infected, ARV naïve patients is associated with renal insufficiency and increased mortality,

    JOURNAL OF MEDICAL VIROLOGY, Issue 9 2008
    Raveen Parboosing
    Abstract HIV is known to affect the epidemiology, transmission, pathogenesis and natural history of HCV infection whilst studies on the effects of HCV on HIV have shown conflicting results and are confounded by the influence of intravenous drug use and antiretroviral therapy. This study was conducted in KwaZulu-Natal Province in South Africa where HIV is predominantly a sexually transmitted infection. Intravenous drug use is rare in this region and the study population was naïve to antiretroviral therapy. For this study, specimens from selected sentinel sites submitted to a central laboratory for routine HIV testing were screened for anti-HCV IgG antibodies. HIV positive HCV-positive patients were compared to HIV-positive HCV-negative patients in a subgroup of patients within this cohort in order to determine if HCV sero-prevalence was associated with clinical outcomes in a linked anonymous retrospective chart survey. The prevalence of HCV was 6.4% and that of HIV, 40.2% (n,=,1,937). There was a significantly higher prevalence of HCV among HIV infected patients as compared to HIV negative patients (13.4% vs. 1.73% respectively) (n,=,1,937, P,<,0.001). HCV-HIV co-infected patients had significantly increased mortality (8.3 vs. 21%) (n,=,162, P,<,0.02). A significant association was found between HCV serostatus and abnormal urea levels (15.4 vs. 7.3 mmol/L, n,=,134, P,<,0.001) and creatinine levels (252.2 vs. 144.4 µmol/L, n,=,134, P,<,0.01). This study has found that hepatitis C co-infection is more common in HIV positive individuals and is associated with an increased mortality and renal morbidity. J. Med.

    Ranula: another HIV/AIDS associated oral lesion in Zimbabwe?

    ORAL DISEASES, Issue 4 2004
    MM Chidzonga
    Aim:, To show that sublingual ranula is associated with HIV/AIDS and as such should be considered an HIV/AIDS associated oral lesion in Zimbabwe. Objectives:, To retrospectively study the prevalence, age and gender distribution, the HIV serostatus of ranula patients and the trend in prevalence of ranula and Kaposi's sarcoma (KS) in patients at the two largest referral Oral and Maxillofacial Surgery specialist centres in Harare, Zimbabwe. To use this information to infer an association between ranula and HIV/AIDS in Zimbabwe. Design:, Descriptive study with a retrospective and prospective component. Setting:, Oral and Maxillofacial Surgical clinics at specialist referral hospitals, Harare Central Hospital and Parirenyatwa Government Hospital, Harare, Zimbabwe. Subjects:, Eighty-three cases of ranula were studied: 45 cases retrospectively and 38 consecutively. A total of 231 cases of KS were studied retrospectively. Methods:, Histopathologic records of patients who presented with ranula and KS during the period January 1981 to September 2003 were studied. Gender and age were recorded for each case. Thirty-eight ranula patients studied consecutively during the period June 1999 to September 2003 were consented for HIV testing. Results:, There were 83 cases of ranula; 43.4% male and 56.6% female. There were 231 cases of KS, 61.2% male and 38.8% female. Male to female ratio was 1:1.3 for ranula and for KS was 1:0.6. Ranula was predominant in the 0,10 year age group (73.5%) while KS was most common in the 21,40 year age group (76.4%). Ranula and KS both had a marked rise in prevalence from 1992 to 2003. A total of 88.5% of the ranula cases tested HIV positive with 95% in the 0,10 year age group. Conclusion:, There was a rising prevalence of ranula which mirrors that of KS (an HIV/AIDS associated oral lesion) and that 88.5% of ranula patients were HIV positive with 95% of them in the 0,10 year age group. Sublingual ranula should thus be considered another HIV/AIDS associated lesion in Zimbabwe, especially in children. [source]

    Safety of the Canadian blood supply in 1980,85: using a paediatric cohort for risk assessment of human immunodeficiency virus (HIV) infection

    PAEDIATRIC & PERINATAL EPIDEMIOLOGY, Issue 1 2001
    King
    The risk of HIV from transfusions in Canada in the period 1980,85 was estimated, using the information from a transfused paediatric cohort. Children who were transfused between January 1980 and November 1985 at a tertiary care paediatric hospital were contacted by letter. With this notification, HIV testing for recipients was recommended. HIV testing histories were obtained. The number tested for HIV was estimated from the questionnaire responses and from data matching with the HIV-testing laboratory. Cases of HIV infection were identified through multiple sources. In this cohort, 11 028 children were transfused a mean of 21 units. Of the 10 220 living recipients, the estimated proportion tested for HIV was 86% to 91%. Thirty-one cases of HIV infection were identified, representing 0.28% of the cohort but 0.34% of those expected to have been tested. The estimated HIV incidence per 1000 units transfused ranged from 0.028 [95% CI 0.0007, 0.155] in 1980 to 0.445 [95% CI 0.2592, 0.712] in 1985. This suggests that the risk of HIV from transfusions in Canada continued to rise until the implementation of HIV testing of donors in November 1985. [source]

    Factors determining prenatal HIV testing for prevention of mother to child transmission in Dar Es Salaam, Tanzania

    PEDIATRICS INTERNATIONAL, Issue 2 2007
    MAYUMI KOMINAMI
    Abstract Background: The objectives of the study were (i) to evaluate the Prevention of Mother to Child Transmission (PMTCT) services in Temeke district, Tanzania and (ii) to identify factors for non-acceptance of HIV testing among pregnant mothers in the area. Methods: A structured questionnaire was used in face-to-face interviews at five health centers in the district. Univariate and multiple logistic regression analyses were used to assess the association of the refusal of human immunodeficiency virus (HIV) testing with risk factors. Results: Two hundred and seventy-three (68.1%) of the participants had already had HIV testing, while 128 (31.9%) had not. Participants' general knowledge of HIV was high, but specific knowledge of mother to child transmission (MTCT) was relatively low. In the multiple logistic regression analysis, frequencies of antenatal clinic visits, awareness of MTCT and intensive family support were significantly and inversely associated with the refusal of HIV testing. Conclusions: Frequency of antenatal care visits, spreading information on HIV/acquired immune deficiency syndrome especially MTCT, and husbands' intensive support are significant factors for increase of HIV test acceptance among pregnant women in the study area.

    Associations of Rural Residence With Timing of HIV Diagnosis and Stage of Disease at Diagnosis, South Carolina 2001-2005

    THE JOURNAL OF RURAL HEALTH, Issue 2 2010
    Kristina E. Weis PhD
    Abstract Context: Rural areas in the southern United States face many challenges, including limited access to health care services and stigma, which may lead to later HIV diagnosis among rural residents. Purpose: To investigate the associations of rural residence with timing of HIV diagnosis and stage of disease at diagnosis. Methods: Timing of HIV diagnosis was categorized as a diagnosis of acquired immune deficiency syndrome within 1 year of a first positive HIV test or HIV-only. Stage of disease was based on initial CD4+ T-cell count taken within 1 year of diagnosis. County of residence at HIV diagnosis was classified as urban if the population of the largest city was at least 25,000; it was classified as rural otherwise. Logistic regression was used to analyze timing of HIV diagnosis, and analysis of covariance was used to analyze stage of disease. Findings: From 2001 to 2005, 4,137 individuals were diagnosed with HIV infection. Of these, 1,129 (27%) were rural and 3,008 (73%) were urban residents. Among rural residents, 533 (47%) were diagnosed late, compared with 1,258 (42%) urban residents. Rural residents were significantly more likely to be diagnosed late (OR 1.19 [95% CI, 1.02-1.38]). Rural residence was associated with lower initial CD4+ T-cell count in crude analysis (P= .01) but not after adjustment (P > .05). Conclusions: Rural residence is a risk factor for late HIV diagnosis. This may lead to reduced treatment response to antiretroviral medications, increased morbidity and mortality, and greater HIV transmission risks among rural residents. New testing strategies are needed that address challenges to HIV testing and diagnosis specific to rural areas. [source]

    Sexual Health Among U.S. Black and Hispanic Men and Women: A Nationally Representative Study

    THE JOURNAL OF SEXUAL MEDICINE, Issue 2010
    Brian Dodge PhD
    ABSTRACT Introduction., Little is known about the prevalence of sexual behaviors among the black and Hispanic populations in the United States outside the context of sexual risk and disease transmission in "high-risk" samples. Aim., This study sought to establish current rates of sexual behaviors, sexual health care practices (i.e., experiences with testing and diagnosis of sexually transmitted infections [STIs]), and condom use in a probability sample of black and Hispanic adult men and women in the United States. Main Outcome Measures., Sexual behaviors including solo masturbation, partnered masturbation, receiving oral sex and giving oral sex, vaginal intercourse, and anal intercourse were assessed. Self-reported rates of HIV and other STI testing, and self-reported history of STI diagnosis were examined. Also assessed were rates of condom use during most recent and past 10 vaginal intercourse events. Methods., Data from a probability sample of 1246 black and Hispanic adults were analyzed to explore sexual behaviors, condom use, and STI testing and diagnosis trends. Results., Masturbation, oral sex, and vaginal intercourse were prevalent among black and Hispanic men and women throughout the life course. Anal intercourse and same-gender sexual activities were less common. Self-reported rates of HIV testing were relatively high but varied by gender across age groups. Similarly, rates of testing for other STI were high and differed by gender across age groups. Overall rates of condom use among black and Hispanic men and women were relatively high and did not appear to be related to a variety of situational factors including location of sexual encounter, relationship status, other contraceptive use, and substance use during sexual activity. Conclusion., These data provide a foundation for understanding diverse sexual behaviors, sexual health-care practices, and condom use among the general population of black and Hispanic men and women in the United States.

    Emergency Medicine Resident Attitudes and Perceptions of HIV Testing Before and After a Focused Training Program and Testing Implementation

    ACADEMIC EMERGENCY MEDICINE, Issue 11 2009
    Yu-Hsiang Hsieh MSc
    Abstract Objectives:, The objectives were to determine attitudes and perceptions (A&P) of emergency medicine (EM) residents toward emergency department (ED) routine provider-driven rapid HIV testing services and the impact of both a focused training program (FTP) and implementation of HIV testing on A&P. Methods:, A three-phase, consecutive, anonymous, identity-unlinked survey was conducted pre-FTP, post-FTP, and 6 months postimplementation. The survey was designed to assess residents' A&P using a five-point Likert scale. A preimplementation FTP provided both the rationale for the HIV testing program and the planned operational details of the intervention. The HIV testing program used only indigenous ED staff to deliver HIV testing as part of standard-of-care in an academic ED. The impact of the FTP and implementation on A&P were analyzed by multivariate regression analysis using generalized estimating equations to control for repeated measurements in the same individuals. A "favorable" A&P was operationally defined as a mean score of >3.5, "neutral" as mean score of 2.5 to 3.5, and "unfavorable" as mean score of <2.5. Results:, Thirty of 36 residents (83.3%) participated in all three phases. Areas of favorable A&P found in phase I and sustained through phases II and III included "ED serving as a testing venue" (score range = 3.7,4.1) and "emergency medicine physicians offering the test" (score range = 3.9,4.1). Areas of unfavorable and neutral A&P identified in phase I were all operational barriers and included required paperwork (score = 3.2), inadequate staff support (score = 2.2), counseling and referral requirements (score range = 2.2,3.1), and time requirements (score = 2.9). Following the FTP, significant increases in favorable A&P were observed with regard to impact of the intervention on modification of patient risk behaviors, decrease in rates of HIV transmission, availability of support staff, and self-confidence in counseling and referral (p < 0.05). At 6 months postimplementation, all A&P except for time requirements and lack of support staff scored favorably or neutral. During the study period, 388 patients were consented for and received HIV testing; six (1.5%) were newly confirmed HIV positive. Conclusions:, Emergency medicine residents conceptually supported HIV testing services. Most A&P were favorably influenced by both the FTP and the implementation. All areas of negative A&P involved operational requirements, which may have influenced the low overall uptake of HIV testing during the study period. [source]

    Design and Implementation of a Controlled Clinical Trial to Evaluate the Effectiveness and Efficiency of Routine Opt-out Rapid Human Immunodeficiency Virus Screening in the Emergency Department

    ACADEMIC EMERGENCY MEDICINE, Issue 8 2009
    Jason S. Haukoos MD
    Abstract In 2006, the Centers for Disease Control and Prevention (CDC) released revised recommendations for performing human immunodeficiency virus (HIV) testing in health care settings, including implementing routine rapid HIV screening, the use of an integrated opt-out consent, and limited prevention counseling. Emergency departments (EDs) have been a primary focus of these efforts. These revised CDC recommendations were primarily based on feasibility studies and have not been evaluated through the application of rigorous research methods. This article describes the design and implementation of a large prospective controlled clinical trial to evaluate the CDC's recommendations in an ED setting. From April 15, 2007, through April 15, 2009, a prospective quasi-experimental equivalent time-samples clinical trial was performed to compare the clinical effectiveness and efficiency of routine (nontargeted) opt-out rapid HIV screening (intervention) to physician-directed diagnostic rapid HIV testing (control) in a high-volume urban ED. In addition, three nested observational studies were performed to evaluate the cost-effectiveness and patient and staff acceptance of the two rapid HIV testing methods. This article describes the rationale, methodologies, and study design features of this program evaluation clinical trial. It also provides details regarding the integration of the principal clinical trial and its nested observational studies. Such ED-based trials are rare, but serve to provide valid comparisons between testing approaches. Investigators should consider similar methodology when performing future ED-based health services research. [source]

    High HIV testing and low HIV prevalence among injecting drug users attending the Sydney Medically Supervised Injecting Centre

    Abstract Objective: Measure the self-reported prevalence of HIV, history of HIV testing and associated risk factors among injecting drug users (IDUs) attending the Sydney Medically Supervised Injecting Centre (MSIC). Methods: Cross-sectional survey of IDUs attending the Sydney MSIC (n=9,778). Results: The majority of IDUs had been tested for HIV (94%), most within the preceding 12 months. Self-reported prevalence of HIV was only 2% (n=162) and homosexuality (AOR 20.68), bisexuality (AOR 5.30), male gender (AOR 3.33), mainly injecting psychostimulants (AOR 2.02), use of local health service (AOR 1.56) and increasing age (AOR 1.62) were independently associated. Among the 195 homosexual male sample 23% were self-reported being HIV positive. HIV positive homosexual males were more likely to report mainly psychostimulant injecting than other drugs, a finding not replicated among the heterosexual males. Conclusions: The associations in this sample are consistent with other data indicating Australia has successfully averted an epidemic of HIV among heterosexual IDUs. The absence of any significant associations between HIV positive sero-status and the injecting-related behaviours that increase vulnerability to BBV transmission suggests that HIV infection in this group may be related to sexual behaviours. In particular, the strong associations between homosexual males and psychostimulant injectors with HIV positive sero-status suggests that patterns of infection within this group reflect the epidemiology of HIV in Australia more generally, where men who have sex with men remain most vulnerable to infection.

    Video as an Effective Method to Deliver Pretest Information for Rapid Human Immunodeficiency Testing

    ACADEMIC EMERGENCY MEDICINE, Issue 2 2009
    Roland C. Merchant MD
    Abstract Objectives:, Video-based delivery of human immunodeficiency virus (HIV) pretest information might assist in streamlining HIV screening and testing efforts in the emergency department (ED). The objectives of this study were to determine if the video "Do you know about rapid HIV testing?" is an acceptable alternative to an in-person information session on rapid HIV pretest information, in regard to comprehension of rapid HIV pretest fundamentals, and to identify patients who might have difficulties in comprehending pretest information. Methods:, This was a noninferiority trial of 574 participants in an ED opt-in rapid HIV screening program who were randomly assigned to receive identical pretest information from either an animated and live-action 9.5-minute video or an in-person information session. Pretest information comprehension was assessed using a questionnaire. The video would be accepted as not inferior to the in-person information session if the 95% confidence interval (CI) of the difference (,) in mean scores on the questionnaire between the two information groups was less than a 10% decrease in the in-person information session arm's mean score. Linear regression models were constructed to identify patients with lower mean scores based upon study arm assignment, demographic characteristics, and history of prior HIV testing. Results:, The questionnaire mean scores were 20.1 (95% CI = 19.7 to 20.5) for the video arm and 20.8 (95% CI = 20.4 to 21.2) for the in-person information session arm. The difference in mean scores compared to the mean score for the in-person information session met the noninferiority criterion for this investigation (, = 0.68; 95% CI = 0.18 to 1.26). In a multivariable linear regression model, Blacks/African Americans, Hispanics, and those with Medicare and Medicaid insurance exhibited slightly lower mean scores, regardless of the pretest information delivery format. There was a strong relationship between fewer years of formal education and lower mean scores on the questionnaire. Age, gender, type of insurance, partner/marital status, and history of prior HIV testing were not predictive of scores on the questionnaire. Conclusions:, In terms of patient comprehension of rapid HIV pretest information fundamentals, the video was an acceptable substitute to pretest information delivered by an HIV test counselor. Both the video and the in-person information session were less effective in providing pretest information for patients with fewer years of formal education. [source]

    Nomenclature and Definitions for Emergency Department Human Immunodeficiency Virus (HIV) Testing: Report from the 2007 Conference of the National Emergency Department HIV Testing Consortium

    ACADEMIC EMERGENCY MEDICINE, Issue 2 2009
    Michael S. Lyons MD
    Abstract Early diagnosis of persons infected with human immunodeficiency virus (HIV) through diagnostic testing and screening is a critical priority for individual and public health. Emergency departments (EDs) have an important role in this effort. As EDs gain experience in HIV testing, it is increasingly apparent that implementing testing is conceptually and operationally complex. A wide variety of HIV testing practice and research models have emerged, each reflecting adaptations to site-specific factors and the needs of local populations. The diversity and complexity inherent in nascent ED HIV testing practice and research are associated with the risk that findings will not be described according to a common lexicon. This article presents a comprehensive set of terms and definitions that can be used to describe ED-based HIV testing programs, developed by consensus opinion from the inaugural meeting of the National ED HIV Testing Consortium. These definitions are designed to facilitate discussion, increase comparability of future reports, and potentially accelerate wider implementation of ED HIV testing. [source]

    Preventing mother-to-child transmission of HIV

    BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 2009
    CN Mnyani
    HIV transmission from mother-to-child remains a major cause of infant morbidity and mortality in resource-poor settings. There is consensus that women who need antiretroviral treatment should receive this during pregnancy and beyond, and that an appropriate antiretroviral prophylactic regimen should be given to those who do not yet need ongoing therapy. Infant feeding remains a major source of infection and new antiretroviral strategies, for mothers or children, are emerging with the potential to control this. Access to HIV testing and antiretroviral treatment or prophylaxis remain very limited in low resource settings and needs to be expanded. [source]

    Objectives, The proportion of women delivering with known HIV status in sub-Saharan Africa is not well described. Risk of HIV transmission to newborns is a major concern, but there may also be increased risks for other adverse pregnancy outcomes. Design, Hospital registry. Setting, North East Tanzania (1999,2006). Population, Singletons (n= 14 444). Methods, Births were grouped by maternal HIV status and socio-demographic factors predicting HIV status, and associations between status and pregnancy outcomes were studied. Main outcome measures, Maternal HIV status, perinatal mortality, prematurity, small for gestational age (SGA), birthweight and low Apgar score. Results, The proportion of mothers with known HIV status increased from 7% before 2001 to 78% after 2004. Single motherhood, rural residence, low maternal education, maternal and paternal farming and higher paternal age were associated with unknown HIV status. About 7.4% (95% CI 6.7,8.1%) of women were HIV infected, with increased likelihood of infection with higher gravidity, single motherhood, rural residence, maternal business or farming occupations and paternal tribe. Compared with HIV-uninfected women, the untreated HIV-infected women had a higher risk of SGA births (adjusted risk ratio [ARR] 1.6; 95% CI 1.1,2.4), preterm birth (ARR 1.8; 95% CI 1.1,2.7) and perinatal death (ARR 1.9; 95% CI 0.95,3.8). Women with unknown HIV status had moderately increased risks. Treated HIV-infected women had a risk similar to that of the HIV-uninfected women for all outcomes, except for low Apgar score. Conclusion, HIV testing and infection were associated with socio-demographic factors. Untreated HIV-infected women had higher risks of adverse pregnancy outcomes, and risks were also increased for women with unknown HIV status. There is still a need to increase availability of HIV testing, education and adequate therapy for pregnant women. [source]

    Pregnancy outcomes and antiretroviral treatment in a national cohort of pregnant women with HIV: overall rates and differences according to nationality

    We used data from the main surveillance study of HIV and pregnancy in Italy to evaluate possible differences in pregnancy care and outcomes according to nationality. Among 960 women followed in 2001,06, 33.5% were of foreign nationality, mostly from African countries. Foreign women had lower rates of preconception counselling and planning of pregnancy. They had more frequently HIV diagnosed during pregnancy, with a later start of antiretroviral treatment and lower treatment rates at all trimesters but not when the entire pregnancy, including delivery, was considered. No differences were observed between the two groups in ultrasonography assessments, hospitalisations, AIDS events, intrauterine or neonatal deaths, and mode and complications of delivery. Foreign women had a slightly lower occurrence of preterm delivery and infants with low birthweight. The results indicate good standards of care and low rates of adverse outcomes in pregnant women with HIV in Italy, irrespective of nationality. Specific interventions, however, are needed to increase the rates of counselling and HIV testing before pregnancy in foreign women. [source]

    Availability of Rapid Human Immunodeficiency Virus Testing in Academic Emergency Departments

    ACADEMIC EMERGENCY MEDICINE, Issue 2 2008
    Peter D. Ehrenkranz MD
    Abstract Objectives:, The Centers for Disease Control and Prevention (CDC) recommends routine human immunodeficiency virus (HIV) screening of emergency department (ED) patients aged 13 to 64 years. The study objectives were to determine the accessibility of rapid HIV testing in academic EDs, to identify factors that influence an ED's adoption of testing, and to describe current HIV testing practices. Methods:, Online surveys were sent to EDs affiliated with emergency medicine (EM) residency programs (n = 128), excluding federal hospitals and facilities in U.S. territories. Eighty percent (n = 102) responded. Most e-mail recipients (n = 121) were Emergency Medicine Network (EMNet) investigators; remaining contacts were obtained from residency-related Web sites. Results:, Most academic EDs (n = 58; 57%; 95% confidence interval (CI) = 47% to 66%) offer rapid HIV testing. Among this group, 26 (45%) allow providers to order tests without restrictions. Of the other 32 EDs, 100% have policies allowing for rapid HIV testing following occupational exposures, but less than 10% have guidelines for testing in other clinical situations. Forty-seven percent expect to routinely offer HIV testing in the next 2 to 3 years. Only 59% of the EDs that offered rapid tests in any situation could link an HIV-positive patient to subspecialty care. The facility characteristic most important to availability of rapid HIV testing was the presence of on-site HIV counselors. Conclusions:, Most academic EDs now offer rapid HIV testing (57%), but few use it in situations other than occupational exposure. Less than half of academic EDs expect to implement CDC guidelines regarding routine screening within the next few years. The authors identified facility characteristics (e.g., counseling, ability to refer) that may influence adoption of rapid HIV testing. [source]
