    Full Text Available The Acquired Immune Deficiency Syndrome epidemic, caused by the Human Immunodeficiency Virus, is a global crisis which threatens development gains, economies, and societies. Within sub-Saharan Africa, where the epidemic began the earliest and the HIV prevalence is the highest, African countries have death rates not seen before. In South Africa the epidemic has a devastating impact which creates profound suffering on individuals and their families, and the impact on the socio-economic level is of great concern. The eradication of HIV/AIDS represents one of humanity’s greatest challenges, which requires co-operation and comprehensive collaboration between many different role players. In this endeavour clinical information plays a major role. To combat the effect of the disease, the Free State Department of Health started with the provisioning of antiretroviral therapy in the public health sector. The objective of this paper was to address the challenges they faced in order to develop and implement an information system to manage the rollout of antiretroviral treatment effectively. They started with a paper-based system to collect vital information. It was followed by a palm computer project that was initiated to electronically capture the data collected by the paper-based system. This system was then replaced by a comprehensive Hospital and Clinic Information System which was acquired and customised for the antiretroviral data collection process. Research partners developed a standalone antiretroviral data warehouse for collecting information associated with the monitoring and evaluation of the Free State antiretroviral and HIV/ AIDS treatment programme. The data warehouse successfully produced several management information reports to the antiretroviral management team. A need was identified to design a comprehensive antiretroviral data warehouse that will integrate data from several operational sources which are all associated with HIV/AIDS.

    Background The antiretroviral adherence club intervention was rolled out in primary health care facilities in the Western Cape province of South Africa to relieve clinic congestion, and improve retention in care, and treatment adherence in the face of growing patient loads. We adopted the realist evaluation approach to evaluate what aspects of antiretroviral club intervention works, for what sections of the patient population, and under which community and health systems contexts, to inform guidelines for scaling up of the intervention. In this article, we report on a step towards the development of a programme theory—the assumptions of programme designers and health service managers with regard to how and why the adherence club intervention is expected to achieve its goals and perceptions on how it has done so (or not). Methods We adopted an exploratory qualitative research design. We conducted a document review of 12 documents on the design and implementation of the adherence club intervention, and key informant interviews with 12 purposively selected programme designers and managers. Thematic content analysis was used to identify themes attributed to the programme actors, context, mechanisms, and outcomes. Using the context-mechanism-outcome configurational tool, we provided an explanatory focus of how the adherence club intervention is roll-out and works guided by the realist perspective. Results We classified the assumptions of the adherence club designers and managers into the rollout, implementation, and utilisation of the adherence club programme, constructed around the providers, management/operational staff, and patients, respectively. Two rival theories were identified at the patient-perspective level. We used these perspectives to develop an initial programme theory of the adherence club intervention, which will be tested in a later phase. Conclusion The perspectives of the programme designers and managers provided an important step towards developing

    Full Text Available Introduction: Lesotho was among the first countries to adopt decentralization of care from hospitals to nurse-led health centres (HCs to scale up the provision of antiretroviral therapy (ART. We compared outcomes between patients who started ART at HCs and hospitals in two rural catchment areas in Lesotho. Methods: The two catchment areas comprise two hospitals and 12 HCs. Patients ≥16 years starting ART at a hospital or HC between 2008 and 2011 were included. Loss to follow-up (LTFU was defined as not returning to the facility for ≥180 days after the last visit, no follow-up (no FUP as not returning after starting ART, and retention in care as alive and on ART at the facility. The data were analysed using logistic regression, competing risk regression and Kaplan-Meier methods. Multivariable analyses were adjusted for sex, age, CD4 cell count, World Health Organization stage, catchment area and type of ART. All analyses were stratified by gender. Results: Of 3747 patients, 2042 (54.5% started ART at HCs. Both women and men at hospitals had more advanced clinical and immunological stages of disease than those at HCs. Over 5445 patient-years, 420 died and 475 were LTFU. Kaplan-Meier estimates for three-year retention were 68.7 and 69.7% at HCs and hospitals, respectively, among women (p=0.81 and 68.8% at HCs versus 54.7% at hospitals among men (p<0.001. These findings persisted in adjusted analyses, with similar retention at HCs and hospitals among women (odds ratio (OR: 0.89, 95% confidence interval (CI: 0.73–1.09 and higher retention at HCs among men (OR: 1.53, 95% CI: 1.20–1.96. The latter result was mainly driven by a lower proportion of patients LTFU at HCs (OR: 0.68, 95% CI: 0.51–0.93. Conclusions: In rural Lesotho, overall retention in care did not differ significantly between nurse-led HCs and hospitals. However, men seemed to benefit most from starting ART at HCs, as they were more likely to remain in care in these facilities

    The Joint United Nations Programme on HIV/AIDS (UNAIDS) has set the global goal of ending the AIDS world epidemic by 2030. In order to end this epidemic they have established a 90-90-90 goal to be achieved by 2020, which may be problematic, especially in low- and middle-income countries. This goal includes 90% of individuals with HIV globally being diagnosed, on treatment, and virologically suppressed. Based on global estimates from 2014-2015, approximately 36.9 million individuals are living with HIV. Of those, 53% have been diagnosed with HIV, 41% are on antiretroviral therapy (ART), and 32% have viral suppression with <1000 copies/ml. Comprehensive approaches are needed to improve the number of people living with HIV (PLWH) who are diagnosed, linked, and engaged in care. Once PLWH are retained in care, treatment is key to both HIV prevention and transmission. The development and advancement of new ART is necessary to assist in reaching these goals by improving safety profiles, decreasing pill burden, improving quality of life and life expectancy, and creating new mechanisms to overcome resistance. The focus of this review is to highlight and review data for antiretroviral agents recently added to the market as well as discuss agents in various stages of development (new formulations and mechanisms of action).

    Full Text Available Abstract Background There is little knowledge regarding the prevalence and nature of renal impairment in African populations initiating antiretroviral treatment, nor evidence to inform the most cost effective methods of screening for renal impairment. With the increasing availability of the potentially nephrotixic drug, tenofovir, such information is important for the planning of antiretroviral programmes Methods (i Retrospective review of the prevalence and risk factors for impaired renal function in 2189 individuals initiating antiretroviral treatment in a rural African setting between 2004 and 2007 (ii A prospective study of 149 consecutive patients initiating antiretrovirals to assess the utility of urine analysis for the detection of impaired renal function. Severe renal and moderately impaired renal function were defined as an estimated GFR of ≤ 30 mls/min/1.73 m2 and 30–60 mls/min/1.73 m2 respectively. Logistic regression was used to determine odds ratio (OR of significantly impaired renal function (combining severe and moderate impairment. Co-variates for analysis were age, sex and CD4 count at initiation. Results (i There was a low prevalence of severe renal impairment (29/2189, 1.3% 95% C.I. 0.8–1.8 whereas moderate renal impairment was more frequent (287/2189, 13.1% 95% C.I. 11.6–14.5 with many patients having advanced immunosuppression at treatment initiation (median CD4 120 cells/μl. In multivariable logistic regression age over 40 (aOR 4.65, 95% C.I. 3.54–6.1, male gender (aOR 1.89, 95% C.I. 1.39–2.56 and CD4 Conclusion In this rural African setting, significant renal impairment is uncommon in patients initiating antiretrovirals. Urine analysis alone may be inadequate for identification of those with impaired renal function where resources for biochemistry are limited.

    Full Text Available Abstract Background In many HIV programmes in Africa, patients are assessed clinically and prepared for antiretroviral treatment over a period of 4–12 weeks. Mortality rates following initiation of ART are very high largely because patients present late with advanced disease. The rates of mortality and retention during the pre-treatment period are not well understood. We conducted an observational study to determine these rates. Methods HIV-infected subjects presenting at The AIDS Support Clinic in Jinja, SE Uganda, were assessed for antiretroviral therapy (ART. Eligible subjects were given information and counselling in 3 visits done over 4–6 weeks in preparation for treatment. Those who did not complete screening were followed-up at home. Survival analysis was done using poisson regression. Results 4321 HIV-infected subjects were screened of whom 2483 were eligible for ART on clinical or immunological grounds. Of these, 637 (26% did not complete screening and did not start ART. Male sex and low CD4 count were associated independently with not completing screening. At follow-up at a median 351 days, 181 (28% had died, 189 (30% reported that they were on ART with a different provider, 158 (25% were alive but said they were not on ART and 109 (17% were lost to follow-up. Death rates (95% CI per 100 person-years were 34 (22, 55 (n.18 within one month and 37 (29, 48 (n.33 within 3 months. 70/158 (44% subjects seen at follow-up said they had not started ART because they could not afford transport. Conclusion About a quarter of subjects eligible for ART did not complete screening and pre-treatment mortality was very high even though patients in this setting were well informed. For many families, the high cost of transport is a major barrier preventing access to ART.

    Full Text Available Abstract Background HIV infection among children, particularly those under 24 months of age, is often rapidly progressive; as a result guidelines recommend earlier access to combination antiretroviral therapy (cART for HIV infected children. Losses to follow-up (LTFU and death in the interval between diagnosis and initiation of ART profoundly limit this strategy. This study explores correlates of LTFU and death prior to ART initiation among children. Methods The study is based on 337 HIV-infected children enrolled into care at an urban centre in The Gambia, including those alive and in care when antiretroviral therapy became available and those who enrolled later. Children were followed until they started ART, died, transferred to another facility, or were LTFU. Cox proportional hazards regression models were used to determine the hazard of death or LTFU according to the baseline characteristics of the children. Results Overall, 223 children were assessed as eligible for ART based on their clinical and/or immunological status among whom 73 (32.7% started treatment, 15 (6.7% requested transfer to another health facility, 105 (47.1% and 30 (13.5% were lost to follow-up and died respectively without starting ART. The median survival following eligibility for children who died without starting treatment was 2.8 months (IQR: 0.9 - 5.8 with over half (60% of all deaths occurring at home. ART-eligible children less than 2 years of age and those in WHO stage 3 or 4 were significantly more likely to be LTFU when compared with their respective comparison groups. The overall pre-treatment mortality rate was 25.7 per 100 child-years of follow-up (95% CI 19.9 - 36.8 and the loss to programme rate was 115.7 per 100 child-years of follow-up (95% CI 98.8 - 137. In the multivariable Cox proportional hazard model, significant independent predictors of loss to programme were being less than 2 years of age and WHO stage 3 or 4. The Adjusted Hazard Ratio

    Full Text Available To determine the frequency and patterns of acquired antiretroviral drug resistance in a rural primary health care programme in South Africa.Cross-sectional study nested within HIV treatment programme.Adult (≥ 18 years HIV-infected individuals initially treated with a first-line stavudine- or zidovudine-based antiretroviral therapy (ART regimen and with evidence of virological failure (one viral load >1000 copies/ml were enrolled from 17 rural primary health care clinics. Genotypic resistance testing was performed using the in-house SATuRN/Life Technologies system. Sequences were analysed and genotypic susceptibility scores (GSS for standard second-line regimens were calculated using the Stanford HIVDB 6.0.5 algorithms.A total of 222 adults were successfully genotyped for HIV drug resistance between December 2010 and March 2012. The most common regimens at time of genotype were stavudine, lamivudine and efavirenz (51%; and stavudine, lamivudine and nevirapine (24%. Median duration of ART was 42 months (interquartile range (IQR 32-53 and median duration of antiretroviral failure was 27 months (IQR 17-40. One hundred and ninety one (86% had at least one drug resistance mutation. For 34 individuals (15%, the GSS for the standard second-line regimen was <2, suggesting a significantly compromised regimen. In univariate analysis, individuals with a prior nucleoside reverse-transcriptase inhibitor (NRTI substitution were more likely to have a GSS <2 than those on the same NRTIs throughout (odds ratio (OR 5.70, 95% confidence interval (CI 2.60-12.49.There are high levels of drug resistance in adults with failure of first-line antiretroviral therapy in this rural primary health care programme. Standard second-line regimens could potentially have had reduced efficacy in about one in seven adults involved.

    Full Text Available Abstract Background HIV/AIDS and depression are projected to be the two leading causes of disability by 2030. HIV/AIDS and anxiety/depression are interlinked. People suffering from depression may be more likely to engage in risky sexual behaviour, and therefore at greater risk of contracting HIV. An HIV + diagnosis may trigger symptoms of anxiety and depression, which may in turn result in risky sexual behaviour and the spread of HIV. This study explores correlates of anxiety and depression in patients enrolled in a public sector ART programme in South Africa. Methods Interviews were conducted with 716 patients initiating ART at twelve public health care facilities in the Free State. Symptoms of anxiety and depression were measured using the Hospital Anxiety and Depression Scale (HADS. An 8+ cut-off was used to identify possible cases of anxiety and depression. Multivariate logistic regression analysis, using STATA Version 11, was performed to identify correlates of anxiety and depression. Results The prevalence of symptoms of respectively anxiety and depression amongst this study population in the Free State was 30.6% and 25.4%. The multivariate logistic regression analyses identified five correlates of symptoms of anxiety and depression. Disruptive side effects (OR = 3.62, CI 1.95-6.74 and avoidant coping (OR = 1.42, CI 1.22-1.65 were associated with a greater number of symptoms of anxiety. Stigma was associated with an increase in symptoms of anxiety (OR = 1.14, CI 1.07-1.21 and of depression (OR = 1.13, CI 1.06-1.20, while being a widow (OR = 0.30, CI 0.13-0.69 and participating in a support group (OR = 0.21, CI 0.05-0.99 were associated with decreased symptoms of depression. Conclusions The findings from the study provide valuable insights into the psychosocial aspects of the Free State public-sector ART programme. Combined with the literature on the intricate link between mental health problems and treatment outcomes our results emphasise

    Full Text Available Abstract Background Many national antiretroviral therapy (ART programmes encourage providers to identify and address baseline factors associated with poor treatment outcomes, including modifiable adherence-related behaviours, before initiating ART. However, evidence on such predictors is scarce, and providers judgement may often be inaccurate. To help address this evidence gap, this observational cohort study examined baseline factors potentially predictive of poor treatment outcomes in two ART programmes in South Africa, with a particular focus on determinants of adherence. Methods Treatment-naïve patients starting ART were enrolled from a community and a workplace ART programme. Potential baseline predictors associated with poor treatment outcomes (defined as viral load > 400 copies/ml or having discontinued treatment by six months were assessed using logistic regression. Exposure variables were organised for regression analysis using a hierarchical framework. Results 38/227 (17% of participants in the community had poor treatment outcomes compared to 47/117 (40% in the workplace. In the community, predictors of worse outcomes included: drinking more than 20 units of alcohol per week, having no prior experience of chronic medications, and consulting a traditional healer in the past year (adjusted odds ratio [aOR] 15.36, 95% CI 3.22-73.27; aOR 2.30, 95%CI 1.00-5.30; aOR 2.27, 95% CI 1.00-5.19 respectively. Being male and knowing someone on ART were associated with better outcomes (aOR 0.25, 95%CI 0.09-0.74; aOR 0.44, 95%CI 0.19-1.01 respectively. In the workplace, predictors of poor treatment outcomes included being uncertain about the health effects of ART and a traditional healer's ability to treat HIV (aOR 7.53, 95%CI 2.02-27.98; aOR 4.40, 95%CI 1.41-13.75 respectively.

    Full Text Available In South Africa, abacavir (ABC is currently recommended as part of first- and second-line antiretroviral therapy (ART for HIV-positive paediatric patients. Concerns about overprescribing of the drug, particularly to adults, led to an analysis of ABC use in public sector ART programmes. We investigated current prescription of the drug to adults and children accessing ART in 4 public sector programmes across Gauteng Province, South Africa. ABC was almost exclusively prescribed to children initiating ART and adults requiring regimen changes due to drug toxicities. Patterns of ABC use among HIV-positive paediatric patients followed national ART treatment guidelines on the application of the drug. Although ABC is commonly used in the private sector for adults, the current national ART treatment guidelines for adults and adolescents should include ABC as an alternative to standard first- or second-line ART.

    French Guiana is the French territory where the HIV epidemic is most preoccupying. In Cayenne, the mother to child HIV transmission rate was 6% in 2006-2008. Despite free testing and treatment, HIV pregnant women often have delayed or insufficient access to care. The aim of this study was to identify predictive factors of antiretroviral treatmentFrench Guiana) and then to describe their attitudes, practices, and beliefs regarding HIV/AIDS. A case control study was conducted including all deliveries in Cayenne from 2003 to 2010. For each case, a standardized questionnaire including epidemiological, clinical, and biological data was administered. The analysis first described the summary statistics and then bivariate analysis studied the relation of each variable with the outcome. Multivariate analysis adjusted for the confounding factors. Thirty-three women in the first group and 96 in the control group were included in the study. Women born in French Guiana (OR = 5, IC95% = 1.22-20.86, p=0.027) had a high risk of treatment<4 weeks. The other factors associated with treatment<4 weeks in our study were benefiting from food parcels (OR = 12.72, IC95% = 2.07-78.14, p=0.006), consulting a traditional healer when sick (OR = 9.86, IC95% = 2.57-37.88, p= < 0.001), and drug use (OR = 6.27, IC95% = 1.26-31.13, p=0.025). These predictive factors should be considered in prevention programs against mother to child transmission of HIV.

    Sandeep D Patel

    Full Text Available BACKGROUND: In South Africa in 2010, about 340,000 children under the age of 15 were infected with HIV. We describe the increase in the treatment of South African pediatric HIV-infected patients assisted by the President's Emergency Plan for AIDS Relief (PEPFAR from 2004 to 2010. METHODS: We reviewed routine program data from PEPFAR-funded implementing partners among persons receiving antiretroviral treatment age 15 years old and less. Data quality was assessed during the reporting period by program officials through routine analysis of trends and logic checks. Based on UNAIDS estimated mortality rates of untreated HIV-infected children, we calculated the number of deaths averted and life-years gained in children under five receiving PEPFAR-assisted antiretroviral treatment. RESULTS: From October 2004 through September 2010, the number of children newly initiated on antiretroviral treatment in PEPFAR-assisted programs increased from 154 to 2,641 per month resulting in an increase from 2,412 children on antiretroviral treatment in September 2005 to 79,416 children in September 2010. Of those children who initiated antiretroviral treatment before September 2009, 0-4 year olds were 1.4 (95% CI: 1.3-1.5 times as likely to transfer out of the program or die as 5-14 year olds; males were 1.3 (95% CI: 1.0-1.7 times as likely to stop treatment as females. Approximately 27,548 years of life were added to children under-five years old from PEPFAR-assisted antiretroviral treatment. CONCLUSIONS: Pediatric antiretroviral treatment in South Africa has increased substantially. However, additional case-finding and a further acceleration in the implementation of pediatric care and treatment services is required to meet the current treatment need.

  17. The (political) economics of antiretroviral treatment in developing countries.

    2008-12-01

    Despite unprecedented international mobilisation to support universal provision of highly active antiretroviral therapy (HAART), national governments continue to play the key role in determining access to treatment. Whereas some AIDS-affected countries have performed as well as or better than expected given their level of development, institutional characteristics and demographic challenges (e.g. Thailand and Brazil), others (notably South Africa) have not. This article argues that the 'economics' of antiretroviral drug delivery is at heart a political-economy of access to treatment. It depends on commitment on the part of national governments to negotiate with pharmaceutical companies over patented antiretroviral drug prices, on their policy towards compulsory licensing, and on the approach they adopt to delivering HAART. Civil society has an important role to play in encouraging governments to become, and remain, committed to taking action to ensure sustainable and widespread access to HAART.

  18. The Place of protease inhibitors in antiretroviral treatment

    2009-10-01

    Full Text Available With the introduction of highly active antiretroviral therapy, a number of drugs have been developed. The best choice concerning which antiretroviral analogs to start is always under discussion, especially in the choice between non-nucleoside reverse transcriptase inhibitors-based therapies and ritonavir-boosted protease inhibitors. Both are proven to control viral replication and lead to immunological gain. The choice between a non-nucleoside analog reverse transcriptase inhibitor and a protease inhibitor as a third antiretroviral drug in the therapy should consider factors related to the individual, as well as the inclusion of the best therapy in the patient's daily activities and potential adherence. The protease inhibitor-based therapies showed similar efficacy among the various inhibitors with characteristics concerning the adverse events from each medicine. For the treatment of protease-resistant patients, darunavir and tipranavir showed good efficacy with higher genetic barrier to resistance.

    Full Text Available The relationship between characteristics of HIV antiretroviral regimens and treatment adherence was studied in adolescent and adult patients who underwent antiretroviral therapy from January 1998 to September 2000, at the Service for Specialized Assistance in Pelotas. The patients were interviewed on two occasions, and the use of antiretrovirals during the previous 48 hours was investigated by a self-report. Adherence was defined as use of 95% or more of the prescribed medication. Social-demographic variables were collected through direct questionnaires. The antiretroviral regimen and clinical data were copied from the patients' records. Associations between the independent variables and adherence were analyzed by means of logistic regression. The multivariate analysis included characteristics of the antiretroviral regimens, social-demographic variables, as well as perception of negative effects, negative physiological states, and adverse effects of the treatment. Among the 224 selected patients, 194 participated in our study. Their ages varied from 17 to 67 years; most patients were men, with few years of schooling and a low family income. Only 49% adhered to the treatment. Adherence to treatment regimens was reduced when more daily doses were indicated: three to four doses (odds ratio of adherence to treatment (OR=0.47, 95% confidence interval (CI 0.22-1.01 and five to six (OR=0.24, 95% CI 0.09-0.62; two or more doses taken in a fasting state (OR=0.59, 95% CI 0.11-0.68, and for patients who reported adverse effects to the treatment (OR=0.39, 95% CI 0.19-0.77. Most of the regimens with more than two daily doses of medication included at least one dose apart from mealtimes. The results suggest that, if possible, regimens with a reduced number of doses should be chosen, with no compulsory fasting, and with few adverse effects. Strategies to minimize these effects should be discussed with the patients.

    Prompt uptake of antiretroviral treatment (ART) is essential to ensure the success of universal test and treat (UTT) strategies to prevent HIV transmission in high-prevalence settings. We describe ART initiation rates and associated factors within an ongoing UTT cluster-randomized trial in rural South Africa. HIV-positive individuals were offered immediate ART in the intervention arm vs. national guidelines recommended initiation (CD4≤350 cells/mm(3)) in the control arm. We used data collected up to July 2015 among the ART-eligible individuals linked to TasP clinics before January 2015. ART initiation rates at one (M1), three (M3) and six months (M6) from baseline visit were described by cluster and CD4 count strata (cells/mm(3)) and other eligibility criteria: ≤100; 100-200; 200-350; CD4>350 with WHO stage 3/4 or pregnancy; CD4>350 without WHO stage 3/4 or pregnancy. A Cox model accounting for covariate effect changes over time was used to assess factors associated with ART initiation. The 514 participants had a median [interquartile range] follow-up duration of 1.08 [0.69; 2.07] months until ART initiation or last visit. ART initiation rates at M1 varied substantially (36.9% in the group CD4>350 without WHO stage 3/4 or pregnancy, and 55.2-71.8% in the three groups with CD4≤350) but less at M6 (from 85.3% in the first group to 96.1-98.3% in the three other groups). Factors associated with lower ART initiation at M1 were a higher CD4 count and attending clinics with both high patient load and higher cluster HIV prevalence. After M1, having a regular partner was the only factor associated with higher likelihood of ART initiation. These findings suggest good ART uptake within a UTT setting, even among individuals with high CD4 count. However, inadequate staffing and healthcare professional practices could result in prioritizing ART initiation in patients with the lowest CD4 counts. PMID:27421051

    Full Text Available Introduction: Antiretrovirals are available at low prices in sub-Saharan Africa, but these prices may not be consistently available for middle-income countries in other regions with large HIV epidemics. Over 30% of HIV infected people live in countries outside sub-Saharan Africa. Several key antiretrovirals are still on patent, with generic production restricted. We assessed price variations for key antiretroviral drugs inside versus outside sub-Saharan Africa. Methods: HIV drug prices used in national programmes (2010–2014 were extracted from the WHO Global Price Reporting Mechanism database for all reporting middle-income countries as classified by the World Bank. Treatment costs (branded and generic were compared for countries inside sub-Saharan Africa versus those outside. Five key second-line antiretrovirals were analysed: abacavir, atazanavir, darunavir, lopinavir/ritonavir, raltegravir. Results: Prices of branded antiretrovirals were significantly higher outside sub-Saharan Africa (p<0.001, adjusted for year of purchase (see Table 1. For example, the median (interquartile range price of darunavir from Janssen was $732 (IQR $732-806 per person-year in sub-Saharan Africa versus $4689 (IQR $4075-5717 in non-African middle-income countries, an increase of 541%. However, when supplied by generic companies, most antiretrovirals were similarly priced between countries in sub-Saharan Africa and other regions. Conclusions: Pharmaceutical companies are selling antiretrovirals to non-African middle-income countries at prices 74–541% higher than African countries with similar gross national incomes. However, generic companies are selling most of these drugs at similar prices across regions. Mechanisms to ensure fair pricing for patented antiretrovirals across both African and non-African middle-income countries need to be improved, to ensure sustainable treatment access.

    Full Text Available Abstract Patient adherence to treatment is an important factor in the effectiveness of antiretroviral regimens. Adherence to treatment could be monitored by estimation of antiretroviral drugs in biological fluids. We aimed to obtain information on the quantity and duration of excretion of lamivudine in urine following oral administration of a single dose of 300 mg and to assess its suitability for adherence monitoring purposes. Spot urine samples were collected before dosing and at 4, 8, 12, 24, 28, 32, 48, 72, and 96 hours post dosing from 10 healthy subjects, and lamivudine was estimated by high-pressure liquid chromatography (HPLC. Lamivudine values were expressed as a ratio of urine creatinine. About 91% of the ingested drug was excreted by 24 hours, and the concentration thereafter in urine was very negligible. A lamivudine value of 0.035 mg/mg creatinine or less at 48 hours is suggestive of a missed dose in the last 24 hours. The study findings showed that estimation of urine lamivudine in spot specimens could be useful in monitoring patient adherence to antiretroviral treatment. However, this needs to be confirmed on a larger sample size and among patients on once-daily and twice-daily treatment regimens.

    Full Text Available Introduction: Adherence to antiretroviral treatment (ART is critical to maintaining health and good clinical outcomes in people living with HIV/AIDS. To address poor treatment adherence, low-cost interventions using mobile communication technology are being studied. While there are some studies that show an effect of mobile phone reminders on adherence to ART, none has reported on the costs of such reminders for national AIDS programmes. This paper aims to study the costs of mobile phone reminder strategies (mHealth interventions to support adherence in the context of India's National AIDS Control Program (NACP. Methods: The study was undertaken at two tertiary level teaching hospitals that implement the NACP in Karnataka state, South India. Costs for a mobile phone reminder application to support adherence, implemented at these sites (i.e. weekly calls, messages or both were studied. Costs were collected based on the concept of avoidable costs specific to the application. The costs that were assessed were one-time costs and recurrent costs that included fixed and variable costs. A sequential procedure for costing was used. Costs were calculated at national-programme level, individual ART-centre level and individual patient level from the NACP's perspective. The assessed costs were pooled to obtain an annual cost per patient. The type of application, number of ART centres and number of patients on ART were varied in a sensitivity analysis of costs. Results: The Indian NACP would incur a cost of between 79 and 110 INR (USD 1.27–1.77 per patient per year, based on the type of reminder, the number of patients on ART and the number of functioning ART centres. The total programme costs for a scale-up of the mHealth intervention to reach the one million patients expected to be on treatment by 2017 is estimated to be 0.36% of the total five-year national-programme budget. Conclusions: The cost of the mHealth intervention for ART-adherence support in

    Full Text Available Abstract Background South Africa recently launched a national antiretroviral treatment programme. This has created an urgent need for nurse-training in antiretroviral treatment (ART delivery. The PALSA PLUS programme provides guidelines and training for primary health care (PHC nurses in the management of adult lung diseases and HIV/AIDS, including ART. A process evaluation was undertaken to document the training, explore perceptions regarding the value of the training, and compare the PALSA PLUS training approach (used at intervention sites with the provincial training model. The evaluation was conducted alongside a randomized controlled trial measuring the effects of the PALSA PLUS nurse-training (Trial reference number ISRCTN24820584. Methods Qualitative methods were utilized, including participant observation of training sessions, focus group discussions and interviews. Data were analyzed thematically. Results Nurse uptake of PALSA PLUS training, with regard not only to ART specific components but also lung health, was high. The ongoing on-site training of all PHC nurses, as opposed to the once-off centralized training provided for ART nurses only at non-intervention clinics, enhanced nurses' experience of support for their work by allowing, not only for ongoing experiential learning, supervision and emotional support, but also for the ongoing managerial review of all those infrastructural and system-level changes required to facilitate health provider behaviour change and guideline implementation. The training of all PHC nurses in PALSA PLUS guideline use, as opposed to ART nurses only, was also perceived to better facilitate the integration of AIDS care within the clinic context. Conclusion PALSA PLUS training successfully engaged all PHC nurses in a comprehensive approach to a range of illnesses affecting both HIV positive and negative patients. PHC nurse-training for integrated systems-based interventions should be prioritized on the ART

    As the severity of the HIV epidemic in China grew, National Free Antiretroviral Treatment (ART) Program was announced since 2003. Even though there still were many difficulties, China had obtained great achievements in fighting against HIV.Over 52 000 adult patients had received first-line HAART thus far and the mortality of AIDS in China decreased significantly. This paper presents an overview of the HIV/AIDS epidemic in China; the status of national free ART program,the difficulties suffered and the achievements made since the initiation of program and the challenges ahead for continued progress for China. This paper also provides suggestions to overcome these challenges.

    Lopinavir/ritonavir (LPV/r) was approved for use in the treatment of human immunodeficiency virus (HIV) infection in 2001 and is the protease inhibitor that has been most widely studied in clinical trials. Despite the time interval since its approval, all the evidence accumulated in the last 14 years indicates that LPV/r continues to occupy an important position among antiretroviral drugs. Firstly, LPV/r plus 2 nucleoside/nucleotide analogs is still considered a good option for initial antiretroviral therapy (ART). Secondly, numerous studies have evaluated the efficacy and safety of new initial ART strategies based on LPV/r in dual therapy. The results obtained suggest that LPV/r plus lamivudine (3TC) or raltegravir can be as effective in initial ART as standard triple therapy and justify their consideration as alternative regimens in this scenario. Thirdly, LPV/r is a pioneer drug, as well as being the agent with the largest amount of evidence from clinical trials on simplification to monotherapy (LPV/r) or dual therapy (LPV/r + 3TC). Lastly, LPV/r is highly useful is special situations. It has a low risk of liver toxicity in patients with chronic liver disease, its use is preferred in the treatment of patients with HIV-2, and it is safe and effective in preventing vertical HIV transmission.

  8. Follow-Up Visit Patterns in an Antiretroviral Therapy (ART programme in Zomba, Malawi.

    Full Text Available Identifying follow-up (FU visit patterns, and exploring which factors influence them are likely to be useful in determining which patients on antiretroviral therapy (ART may become Lost to Follow-Up (LTFU. Using an operation and implementation research approach, we sought 1 to describe the timing of FU visits amongst patients who have been on ART for shorter and longer periods of time; and 2 to determine the median time to late visits, and 3 to identify specific factors that may be associated with these patterns in Zomba, Malawi.Using routinely collected programme monitoring data from Zomba District, we performed descriptive analyses on all ART visits among patients who initiated ART between Jan. 1, 2007-June 30, 2010. Based on an expected FU date, each FU visit was classified as early (≥4 day before an expected FU date, on time (3 days before an expected FU date/up to 6 days after an expected FU date, or late (≥7 days after an expected FU date. In total, 7,815 patients with 76417 FU visits were included. Ninety-two percent of patients had ≥2 FU visits. At the majority of visits, patients were either on time or late. The median time to a first late visit among those with 2 or more visits was 216 days (IQR: 128-359. Various patient- and visit-level factors differed significantly across Early, On Time, and Late visit groups including ART adherence and frequency of, and type of side effects.The majority of patients do not demonstrate consistent FU visit patterns. Individuals were generally on ART for at least 6 months before experiencing their first late visit. Our findings have implications for the development of effective interventions that meet patient needs when they present early and can reduce patient losses to follow-up when they are late. In particular, time-varying visit characteristics need further research.

    2011-06-01

    Full Text Available Abstract Background In 2002, Cameroon initiated scale up of antiretroviral therapy (ART; on 1 October 2004, a substantial reduction in ART cost occurred. We assessed the impact of this event and other factors on enrolment and retention in care among HIV-infected patients initiating ART from February 2002 to December 2005 at the single ART clinic serving the Southwest Region in Limbe, Cameroon. Methods We retrospectively analyzed clinical and pharmacy payment records of HIV-infected patients initiating ART according to national guidelines. We compared two cohorts of patients, enrolled before and after 1 October 2004, to determine if price reduction was associated with enhanced enrolment. We assessed factors associated with retention and survival by Cox proportional hazards models. Retention in care implied patients who had contact with the healthcare system as of 31 December 2005 (including those who were transferred to continue care in other ART centres, although these patients may have interrupted therapy at some time. A patient who was not retained in care may have dropped out (lost to follow up or died. Results Mean enrolment rates for 2920 patients who initiated ART before and after the price reduction were 46.5 and 95.5 persons/month, respectively (p Conclusions Reducing the cost of ART increased enrolment of clients in the programme, but did not change retention in care. In a system where most clients pay for ART, an accessible clinic location may be more important than the cost of medication for retention in care. Decentralizing ART clinics might improve retention and survival among patients on ART.

  10. The impact of HIV, an antiretroviral programme and tuberculosis on mortality in South African platinum miners, 1992-2010.

    Full Text Available BACKGROUND: HIV and tuberculosis (TB are the most common causes of death in South Africa. Antiretroviral therapy (ART programmes should have had an impact on mortality rates. This study describes the impact of HIV, a Wellness (HIV/ART programme and TB on population-wide trends in mortality and causes of death among South African platinum miners, from before the HIV epidemic into the ART era. METHODOLOGY/PRINCIPAL FINDINGS: Retrospective analysis was conducted using routinely-collected data from an open cohort. Mortality and causes of death were determined from multiple sources, including cardiorespiratory autopsy records. All-cause and cause-specific mortality rates were calculated by calendar year. 41,665 male miners were observed for 311,938 person years (py with 3863 deaths. The all-cause age-standardised mortality rate increased from 5.9/1000 py in 1992 to 20.2/1000 py in 2002. Following ART rollout in 2003, annual mortality rates fluctuated between 12.4/1000 py and 19.3/1000 py in the subsequent 7 years. Half of all deaths were HIV-related and 21% were caused by TB. Half (50% of miners who died of HIV after ART rollout had never been registered on the Wellness programme. TB was the most common cause of death in HIV positive miners, increasing from 28% of deaths in the pre-ART period to 41% in the post-ART period. CONCLUSIONS/SIGNIFICANCE: This population-based cohort experienced a rapid increase in mortality from 1996 to 2003 due to increases in HIV and TB mortality. Following ART rollout there was a decrease in mortality, but a steady decrease has not been sustained. Possible explanations for these trends include the changing composition of the workforce, maturation of the HIV epidemic, insufficient uptake of ART and an increase in the proportion of deaths due to TB. In order to make a significant and sustained reduction in mortality in this population, expanding and integrating HIV and TB care and treatment is essential.

    On 3 previous occasions, in 2002, 2003 and 2005, the Swedish Medical Products Agency (Läkemedelsverket) and the Swedish Reference Group for Antiviral Therapy (RAV) have jointly published recommendations for the treatment of HIV infection. An expert group, under the guidance of RAV, has now revised the text again. Since the publication of the previous treatment recommendations, 1 new drug for the treatment of HIV has been approved - the protease inhibitor (PI) darunavir (Prezista). Furthermore, 3 new drugs have become available: the integrase inhibitor raltegravir (MK-0518), the CCR5-inhibitor maraviroc (Celsentri), both of which have novel mechanisms of action, and the non-nucleoside reverse transcriptase inhibitor (NNRTI) etravirine (TMC-125). The new guidelines differ from the previous ones in several respects. The most important of these are that abacavir is now preferred to tenofovir and zidovudine, as a first line drug in treatment-naïve patients, and that initiation of antiretroviral treatment is now recommended before the CD4 cell count falls below 250/microl, rather than 200/microl. Furthermore, recommendations on the treatment of HIV infection in children have been added to the document. As in the case of the previous publication, recommendations are evidence-graded in accordance with the Oxford Centre for Evidence Based Medicine, 2001 (see http://www.cebm.net/levels_of_evidence.asp#levels).

    This paper examines the way gender shaped the health behaviours, health care experiences and narratives of HIV-positive men initiating antiretroviral treatment in South Africa. We conducted participant observation and in-depth, semi-structured interviews with eight men enrolled in a public HIV treatment programme in a rural health district in KwaZulu-Natal. We also interviewed their family members and programme staff. The study found that men's narratives and experiences of antiretroviral therapy (ART) were complex. Descriptions of control and coping juxtaposed with low self-esteem and guilt. Improvements in health following treatment increased optimism about the future but were readily undermined by men's concerns about being unable to meet strongly gendered expectations in relation to family and work. Alcohol use and abuse by men themselves or by family members was found to be an important issue influencing disclosure, uptake and adherence. Given messages discouraging alcohol use during treatment, men reported self-imposed delays to enrolment while they tried to stop or reduce alcohol use, although none had sought advice or professional help in doing so. Men also felt very threatened by alcohol abuse by family members fearing accidental disclose, insults and violence. With regards to health providers, men held strong views as to appropriate and professional behaviour by programme staff, particularly regarding confidentiality. As ART programmes in Africa become established and evolve, we not only need to identify barriers to men's access and adherence but monitor their health and treatment experiences. These findings suggest that the issue of alcohol and ART warrants further investigation. Additional training for primary health care providers and counsellors on health promotion with men may be useful. PMID:20390516

    For children younger than five years, caregivers are responsible for the measurement and administration of antiretroviral medication doses to children. Failure to adhere to the regimen as prescribed may lead to high viral loads (VLs), immune suppression and ultimately drug resistance. In the content of this study, adherence refers to adequate dosing of the medication by a caregiver. Acquired drug resistance to antiretroviral therapy (ART) is prevalent amongst children in South Africa, and poor adherence to the dosing regimen by caregivers may be associated with this problem. In this qualitative study, we purposively recruited 33 caregiver-child dyads from the Hlabisa HIV Treatment and Care Programme database. Children were divided into three groups based on their VL at the time of recruitment. Children with a VL ≥ 400 cps/ml were grouped as unsuppressed (n = 11); children with a VL ≤ 400 cps/ml were grouped as suppressed (n = 12); and children with no VL data were grouped as newly initiated (n = 10). Caregiver-child dyads were visited at their households twice to document, by means of video recording, how treatment was administered to the child. Observational notes and video recordings were entered into ATLAS.ti v 7 and analysed thematically. Results were interpreted through the lens of Ecological Systems Theory and the information-motivation-behavioural skills model was used to understand and reflect on several of the factors influencing adherence within the child's immediate environment as identified in this study. Thematic video analysis indicated context- and medication-related factors influencing ART adherence. Although the majority of children in this sample took their medicine successfully, caregivers experienced several challenges with the preparation and administration of the medications. In the context of emerging drug resistance, efforts are needed to carefully monitor caregiver knowledge of treatment administration by

    Full Text Available Abstract Background HIV-associated anemia is common and associated with poor prognosis. However, its response to antiretroviral treatment (ART in rural Africa is poorly understood. Methods HIV-infected adults (≥15 years who enrolled in HIV care at Haydom Lutheran Hospital in northern Tanzania were included in the study. The effect of ART (zidovudine/stavudine + lamivudine + efavirenz/nevirapine on HIV-associated anemia was studied in a subset of patients who were anemic at the time they started ART and had a follow-up hemoglobin measurement 12 months later. Pregnant women were excluded from the study, as were women who had given birth within the past 6 weeks. Anemia was defined as hemoglobin Results At enrollment, mean hemoglobin was 10.3 g/dL, and 649 of 838 patients (77.4% were anemic. Of the anemic patients, 254 (39.1% had microcytosis and hypochromia. Among 102 patients who were anemic at ART initiation and had a follow-up hemoglobin measurement after 12 months, the mean hemoglobin increased by 2.5 g/dL (P Conclusions Most patients had anemia at enrollment, of whom nearly 40% had microcytosis and hypochromia suggestive of iron deficiency. The mean hemoglobin increased significantly in patients who received ART, but one third were still anemic 12 months after ART initiation indicating that additional interventions to treat HIV-associated anemia in rural Africa might be warranted, particularly in patients with microcytosis and those treated with zidovudine.

    Full Text Available We present a 16-year-old boy, who had presented to us with catatonic features of mutism, withdrawal, passive negativism, grimacing, gesturing, echopraxia, and excitement of 5 days duration while taking antiretroviral therapy (ART for a period of 2 years. He had history of birth asphyxia and acquired HIV infection from his father when the same syringe and needle was used on both of them in a medical setting where the father and son had consulted for treatment of pyrexia of unknown origin. He was the eldest of a three children family in which the biologic father had acquired HIV through extramarital sexual contact with HIV-infected sex workers but was unaware of his HIV positive status till our patient, the 16-year-old was admitted and treated for pulmonary tuberculosis at 14 years of age. The boy′s mother had only acquired HIV after having three children with the HIV-positive husband, thus leaving the other two children HIV negative. The catatonia completely resolved within 2 days after the ART was withheld, and risperidone 1 mg twice a day was prescribed. This case highlights the risks of ART and breach of universal precautions.

We estimated the risk of severe anaemia after initiation of a ZDV-containing regimen in HIV-infected children included in the IeDEA West African database. Methods: Standardized collection of data from HIV-infected children (positive PCR<18 months or positive serology ≥18 months followed up in HIV programmes was included in the regional IeDEA West Africa collaboration. Ten clinical centres from seven countries contributed (Benin, Burkina Faso, Côte d'Ivoire, Gambia, Ghana, Mali and Senegal to this collection. Inclusion criteria were age <16 years and starting ART. We explored the data quality of haemoglobin documentation over time and the incidence and predictors of severe anaemia (Hb<7g/dL per 100 child-years of follow-up over the duration of first-line antiretroviral therapy. Results: As of December 2009, among the 2933 children included in the collaboration, 45% were girls, median age was five years; median CD4 cell percentage was 13%; median weight-for-age z-score was−2.7; and 1772 (60.4% had a first-line ZDV-containing regimen. At baseline, 70% of the children with a first-line ZDV-containing regimen had a haemoglobin measure available versus 76% in those not on ZDV (p≤0.01: the prevalence of severe anaemia was 3.0% (n=38 in the ZDV group versus 10.2% (n=89 in those without (p<0. 01. Over the first-line follow-up, 58.9% of the children had ≥1 measure of haemoglobin available in those exposed to ZDV versus 60.4% of those not (p=0.45. Severe anaemia occurred in 92 children with an incidence of 2.47 per 100 child-years of follow-up in those on a ZDV-containing regimen versus 4.25 in those not (p≤0.01. Adjusted for age at ART initiation and first-line regimen, a weight-for-age z-score ≤−3 was a strong predictor associated with a 5.59 times risk of

    Full Text Available BACKGROUND: The Thai HIV programme is a leader in the public health approach to HIV treatment. Starting at transmission of HIV and ending with transition to adult services this paper assesses the paediatric HIV treatment continuum from three perspectives: service-user, provider and policy maker, to understand what works well and why. METHODS: A qualitative research design was used to assess and triangulate the stakeholder perspectives. Semi-structured interviews were conducted with ART service-users (n = 35, policy actors (n = 20; telephone interviews with prior caregivers of orphans (n = 10; and three focus group discussions with service-providers (hospital staff and volunteers from a district, provincial and a university hospital. FINDINGS: Children accessing HIV care were often orphaned, cared for by elderly relatives and experiencing multiple vulnerabilities. Services were divided into three stages, 1. Diagnosis and linkage: Despite strong policies there were supply and demand-side gaps in the prevention of mother-to-child transmission 'cascade' preventing early diagnosis and/or treatment. 2. Maintenance on ART - Children did well on treatment; caregivers took adherence seriously and valued the quality of services. Drug resistance, adherence and psychosocial issues were important concerns from all perspectives. 3. Adolescents and transition: Adolescent service-users faced greater complexity in their physical and emotional lives for which providers lacked skills; transition from the security of paediatric clinic was a daunting prospect. Dedicated healthcare providers felt they struggled to deliver services that met service-users' diverse needs at all stages. Child- and adolescent-specific elements of HIV policy were considered low priority. CONCLUSIONS: Using the notion of the continuum of care a number of strengths and weaknesses were identified. Features of paediatric services need to evolve alongside the changing needs of service users

    Full Text Available Abstract Background KwaZulu-Natal is the South African province worst affected by HIV and the focus of early modeling studies investigating strategies of antiretroviral treatment (ART delivery. The reality of antiretroviral roll-out through primary care has differed from that anticipated and real world data are needed to inform the planning of further scaling up of services. We investigated the factors associated with uptake of antiretroviral treatment through a primary healthcare system in rural South Africa. Methods Detailed demographic, HIV surveillance and geographic information system (GIS data were used to estimate the proportion of HIV positive adults accessing antiretroviral treatment within northern KwaZulu-Natal, South Africa in the period from initiation of antiretroviral roll-out until the end of 2008. Demographic, spatial and socioeconomic factors influencing the likelihood of individuals accessing antiretroviral treatment were explored using multivariable analysis. Results Mean uptake of ART among HIV positive resident adults was 21.0% (95%CI 20.1-21.9. Uptake among HIV positive men (19.2% was slightly lower than women (21.8%, P = 0.011. An individual's likelihood of accessing ART was not associated with level of education, household assets or urban/rural locale. ART uptake was strongly negatively associated with distance from the nearest primary healthcare facility (aOR = 0.728 per square-root transformed km, 95%CI 0.658-0.963, P = 0.002. Conclusions Despite concerns about the equitable nature of antiretroviral treatment rollout, we find very few differences in ART uptake across a range of socio-demographic variables in a rural South African population. However, even when socio-demographic factors were taken into account, individuals living further away from primary healthcare clinics were still significantly less likely to be accessing ART

    Full Text Available Abstract Background While South Africa spends approximately 7.4% of GDP on healthcare, only 43% of these funds are spent in the public system, which is tasked with the provision of care to the majority of the population including a large proportion of those in need of antiretroviral treatment (ART. South Africa is currently debating the introduction of a National Health Insurance (NHI system. Because such a universal health system could mean increased public healthcare funding and improved access to human resources, it could improve the sustainability of ART provision. This paper considers the minimum resources that would be required to achieve the proposed universal health system and contrasts these with the costs of scaled up access to ART between 2010 and 2020. Methods The costs of ART and universal coverage (UC are assessed through multiplying unit costs, utilization and estimates of the population in need during each year of the planning cycle. Costs are from the provider’s perspective reflected in real 2007 prices. Results The annual costs of providing ART increase from US$1 billion in 2010 to US$3.6 billion in 2020. If increases in funding to public healthcare only keep pace with projected real GDP growth, then close to 30% of these resources would be required for ART by 2020. However, an increase in the public healthcare resource envelope from 3.2% to 5%-6% of GDP would be sufficient to finance both ART and other services under a universal system (if based on a largely public sector model and the annual costs of ART would not exceed 15% of the universal health system budget. Conclusions Responding to the HIV-epidemic is one of the many challenges currently facing South Africa. Whether this response becomes a “resource for democracy” or whether it undermines social cohesiveness within poor communities and between rich and poor communities will be partially determined by the steps that are taken during the next ten years.

    Full Text Available Background: Primary Health Care (PHC clinicians and patients are major role players in the South African antiretroviral treatment programme. Understanding their perceptions and experiences of integrated care and the management of people living with HIV and AIDS in PHC facilities is necessary for successful implementation and sustainability of integration.Objective: This study explored clinician perceptions and patient experiences of integration of antiretroviral treatment in PHC clinics.Method: An exploratory, qualitative study was conducted in four city of Tshwane PHC facilities. Two urban and two rural facilities following different models of integration were included. A self-administered questionnaire with open-ended items was completed by 35 clinicians and four focus group interviews were conducted with HIV-positive patients. The data were coded and categories were grouped into sub-themes and themes.Results: Workload, staff development and support for integration affected clinicians’ performance and viewpoints. They perceived promotion of privacy, reduced discrimination and increased access to comprehensive care as benefits of service integration. Delays, poor patient care and patient dissatisfaction were viewed as negative aspects of integration. In three facilities patients were satisfied with integration or semi-integration and felt common queues prevented stigma and discrimination, whilst the reverse was true in the facility with separate services. Single-month issuance of antiretroviral drugs and clinic schedule organisation was viewed negatively, as well as poor staff attitudes, poor communication and long waiting times.Conclusion: Although a fully integrated service model is preferable, aspects that need further attention are management support from health authorities for health facilities, improved working conditions and appropriate staff development opportunities.

    A dramatic increase in the use of antiretroviral drugs in Africa has increased focus on adherence to treatment, which has so far been equivalent if not superior to that in northern contexts. The reasons for this exceptional adherence are poorly understood. In this paper, we examine adherence in the historical and ethnographic context of access to treatment in Burkina Faso, Côte d'Ivoire and Mali. Living where there is no social security and minimal, if any, medical care, individuals diagnosed with HIV are faced with the threat of illness, death, ostracism and destitution, and were obliged to negotiate conflicting networks of obligation, reciprocity, and value. HIV and AIDS programmes value efforts to address social, and indeed biological, vulnerability. In contrast, kinship-based social relationships may value individuals in other ways. These conflicting moral economies often intersect in the worlds of people living with HIV. HIV status can be used to claim resources from the public or non-governmental organization programmes. This may interfere with social networks that are the most stable source of material and emotional support. Self-help and empowerment techniques provided effective tools for people living with HIV to fashion themselves into effective advocates. In the early years of the use of antiretroviral therapy (ART), access to treatment was thus mediated by confessional practices and forms of social triage. We introduce the term 'therapeutic citizenship' to describe the way in which people living with HIV appropriate ART as a set of rights and responsibilities to negotiate these at times conflicting moral economies. Exemplary adherence should be viewed through the lens of therapeutic citizenship. PMID:18090265

    While the overall percentage of unused antiretroviral medicines returned to the hospital pharmacy is low, their cost is quite high. Adverse events, treatment failure, pharmacokinetic interactions, pregnancy, or treatment simplification are common reasons for unplanned treatment changes. Socially inefficient antiretroviral packages prevent the reuse of drugs returned to the hospital pharmacy. We defined antiretroviral package categories based on the excellence of drug packaging and analyzed the number of pills and costs of drugs returned during a period of 1 year in a hospital-based HIV unit attending to 2,413 treated individuals. A total of 6,090 pills (34% of all returned antiretrovirals) - with a cost of 47,139.91 € - would be totally lost, mainly due to being packed up in the lowest efficiency packages. Newer treatments are packaged in low-excellence categories of packages, thus favoring the maintenance of these hidden costs in the near future. Therefore, costs of this low-efficiency drug packaging, where medication packages are started but not completed, in high-cost medications are substantial and should be properly addressed. Any improvement in the packaging by the manufacturer, and favoring the choice of drugs supplied through efficient packages (when efficacy, toxicity, and convenience are similar), should minimize the treatment expenditures paid by national health budgets.

    Retaining high levels of patients in care who are virally suppressed over long treatment periods has been an important challenge for antiretroviral treatment (ART) programmes in sub-Saharan Africa, the region having the highest HIV burden globally. Clinic-linked community-based adherence support (CBAS) programmes provide home-based adherence and psychosocial support for ART patients. However, there is little evidence of their longer-term impact. This study assessed the effectiveness of CBAS after eight years of ART. CBAS workers are lay healthcare personnel providing regular adherence and psychosocial support for ART patients and their households through home visits addressing household challenges affecting adherence. A multicentre cohort study using routinely collected data was undertaken at six public ART sites in a high HIV-prevalence South African district. Patient retention, loss to follow-up (LTFU), viral suppression and CD4 cell restoration were compared between patients with and without CBAS, using competing-risks regression, linear mixed models and log-binomial regression. 3861 patients were included, of whom 1616 (41.9%) received CBAS. Over 14,792 patient-years of observation, the cumulative incidence of LTFU was 37.3% and 46.2% amongst patients with and without CBAS, respectively, following 8 years of ART; adjusted subhazard ratio (CBAS vs. no CBAS) = 0.74 (95% CI: 0.66-0.84; P resource-limited settings.

    To better understand patient beliefs, which may influence adherence to HIV care and treatment, we examined three dimensions of beliefs among Ethiopian adults (n = 1177) initiating antiretroviral therapy (ART). Beliefs about benefits of ART/HIV clinical care were largely accurate, but few patients believed in the ability of ART to prevent sexual transmission and many thought Holy Water could cure HIV. Factors associated with lower odds of accurate beliefs included advanced HIV, lack of formal education, and Muslim religion (benefits of ART/clinical care); secondary or university education and more clinic visits (ART to prevent sexual transmission); and pregnancy and Orthodox Christian religion (Holy Water). Assessment of patient beliefs may help providers identify areas needing reinforcement. In this setting, counselors also need to stress the benefits of ART as prevention and that Holy Water should not be used to the exclusion of HIV care and ART.

    Full Text Available Abstract Background Tuberculosis (TB is a major contributor to the global burden of disease. In many settings, including South Africa, treatment outcomes remain poor. In contrast, many antiretroviral treatment (ART programmes are achieving high levels of adherence and good outcomes. The ART programme model for maintaining treatment adherence may therefore hold promise for TB treatment. Changing treatment models, however, requires an assessment of how staff receive the new model, as they are responsible for programme implementation. Using the normalization process model as an analytic framework, this paper aims to explore staff perceptions of a new TB treatment programme modelled on the ART treatment programme. Methods A qualitative approach was used. Interviews and focus group discussions were conducted with clinic staff from five intervention clinics. Data were analysed initially using qualitative content analysis. The resulting categories were then organised under the constructs of the normalization process model. Results Staff recounted a number of challenges with implementing the programme. Interviews and focus group discussions identified factors relating to the main categories of the normalization process model. The key issues hindering the normalisation of the programme within clinics related to the interactional workability, relational integration and skill-set workability constructs of the model. These included hierarchical relationships, teamwork, training needs and insufficient internalisation by staff of the empowerment approach included in the programme. Logistical and management issues also impacted negatively on the normalization of the programme at the clinics. Conclusion The normalization process model assisted in categorising the challenges experienced during implementation of the intervention. The results suggest that issues remain that need to be resolved before the programme is implemented more widely. Considerable work is

    Full Text Available BACKGROUND: Genotypic antiretroviral resistance testing (GRT in HIV infection with drug resistant virus is recommended to optimize antiretroviral therapy, in particular in patients with virological failure. We estimated the clinical effect, cost and cost-effectiveness of using GRT as compared to expert opinion in patients with antiretroviral treatment failure. METHODS: We developed a mathematical model of HIV disease to describe disease progression in HIV-infected patients with treatment failure and compared the incremental impact of GRT versus expert opinion to guide antiretroviral therapy. The analysis was conducted from the health care (discount rate 4% and societal (discount rate 2% perspective. Outcome measures included life-expectancy, quality-adjusted life-expectancy, health care costs, productivity costs and cost-effectiveness in US Dollars per quality-adjusted life-year (QALY gained. Clinical and economic data were extracted from the large Swiss HIV Cohort Study and clinical trials. RESULTS: Patients whose treatment was optimized with GRT versus expert opinion had an increase in discounted life-expectancy and quality-adjusted life-expectancy of three and two weeks, respectively. Health care costs with and without GRT were $US 421,000 and $US 419,000, leading to an incremental cost-effectiveness ratio of $US 35,000 per QALY gained. In the analysis from the societal perspective, GRT versus expert opinion led to an increase in discounted life-expectancy and quality-adjusted life-expectancy of three and four weeks, respectively. Health care costs with and without GRT were $US 551,000 and $US 549,000, respectively. When productivity changes were included in the analysis, GRT was cost-saving. CONCLUSIONS: GRT for treatment optimization in HIV-infected patients with treatment failure is a cost-effective use of scarce health care resources and beneficial to the society at large.

    Full Text Available Abstract Background In common with other developing countries, South Africa's public health system is characterised by human resource shortfalls. These are likely to be exacerbated by the escalating demand for HIV care and a large-scale antiretroviral therapy (ART programme. Focusing on professional nurses, the main front-line providers of primary health care in South Africa, we studied patterns of planning, recruitment, training and task allocation associated with an expanding ART programme in the districts of one province, the Free State. Methods Data collection included an audit of professional nurse posts created and filled following the introduction of the ART programme, repeated surveys of facilities providing ART over two years to assess the deployment of staff, and secondary data analysis of government personnel databases to track broader patterns of recruitment and training. Results Although a substantial number of new professional nurse posts were established for the ART programme in the Free State, nearly 80% of these posts were filled by nurses transferring from other programmes within the same facility or from facilities within the same district, rather than by new recruits. From the beginning, ART nurse posts tended to be graded at a senior level, and later, in an effort to recruit professional nurses for the ART programme, the majority (54.6% of nurses entering the programme were promoted to a senior level. The vacancy rate of nurse ART posts was significantly lower than that of other posts in the primary health care (PHC system (15.7% vs 37.1%. Nursing posts in urban ART facilities were more easily filled than those in rural areas, exacerbating existing imbalances. The shift of nurses into the ART programme was partially compensated for by the appointment of additional support staff, task shifting to community health workers, and a large investment in training of PHC workers. However, the use of less-trained, mid-level enrolled

    The first two patients to be treated with miltefosine for post-kala-azar dermal leishmaniasis (PKDL) are reported. One was a 26-year-old Ethiopian man who had been treated with sodium stibogluconate, for relapsing visceral leishmaniasis (VL), four times between August 2002 and March 2004. In January 2004 this patient was found to be seropositive for HIV and began antiretroviral treatment with stavudine, lamivudine and nevirapine. Five months later he developed clinical PKDL, with extensive cu...

    Introduction: Antiretroviral drugs in Spain are delivered by law only in hospital pharmacies. Commercial packages meet variable quality standards when dispensed drugs are returned due to treatment changes or adherence problems Nearly 20–25% of the initial regimens will be changed at 48 weeks for different reasons. We evaluated the economic impact on public health system of the inability of using returned drugs due to inefficient packaging. Materials and Methods: We defined socially efficient ...

    Full Text Available Background: The purpose of this study was to investigate whether there was an association between characteristics of parents and caregivers, and the outcomes of antiretroviral treatment in children younger than 6 years treated at Mildmay Centre in Uganda. Methods: This study was a cross-sectional study based on the review of records. The records of children treated from January 2000 to July 2005 were included in the analysis as part of a larger study. Descriptive and inferential statistics were used in the analysis of data.Results: Of the 179 children, 57.3% were male, 53.4% were 4–5 years, and their median age was 4 years. The majority of children were cared for, in descending order, by their mothers, aunts, grandmothers, and fathers. Whilst 16.0% were orphans of both parents, 56.9% had one of their parents still alive. With regard to outcomes of antiretroviral treatment, it was found that a CD4 count of less than 15% was the most significant predictor of death, when treatment was initiated only at that late stage. When the influence of caregivers’ and parents’ characteristics on the outcomes of treatment were considered, the only factor that was associated significantly with clinical improvement was the ‘father’s unknown human immunodeficiency virus (HIV status’. The data show that when the father was alive, as well as when both parents were alive, the children had a better chance of survival.Conclusion: The nature of the relationship between caregivers and children on antiretroviral treatment, as well as the HIV and living status of their parents seem to have little positive influence on the clinical, immunological, and survival outcomes of the children on treatment. More studies are needed to investigate other characteristics and relationships that may influence the outcomes of treatment.

    IMPORTANCE New data and therapeutic options warrant updated recommendations for the use of antiretroviral drugs (ARVs) to treat or to prevent HIV infection in adults. OBJECTIVE To provide updated recommendations for the use of antiretroviral therapy in adults (aged ≥18 years) with established HIV infection, including when to start treatment, initial regimens, and changing regimens, along with recommendations for using ARVs for preventing HIV among those at risk, including preexposure and postexposure prophylaxis. EVIDENCE REVIEW A panel of experts in HIV research and patient care convened by the International Antiviral Society-USA reviewed data published in peer-reviewed journals, presented by regulatory agencies, or presented as conference abstracts at peer-reviewed scientific conferences since the 2014 report, for new data or evidence that would change previous recommendations or their ratings. Comprehensive literature searches were conducted in the PubMed and EMBASE databases through April 2016. Recommendations were by consensus, and each recommendation was rated by strength and quality of the evidence. FINDINGS Newer data support the widely accepted recommendation that antiretroviral therapy should be started in all individuals with HIV infection with detectable viremia regardless of CD4 cell count. Recommended optimal initial regimens for most patients are 2 nucleoside reverse transcriptase inhibitors (NRTIs) plus an integrase strand transfer inhibitor (InSTI). Other effective regimens include nonnucleoside reverse transcriptase inhibitors or boosted protease inhibitors with 2 NRTIs. Recommendations for special populations and in the settings of opportunistic infections and concomitant conditions are provided. Reasons for switching therapy include convenience, tolerability, simplification, anticipation of potential new drug interactions, pregnancy or plans for pregnancy, elimination of food restrictions, virologic failure, or drug toxicities.

    Introduction Some antiretroviral therapy naïve patients starting combination antiretroviral therapy (cART) experience a limited CD4 count rise despite virological suppression, or vice versa. We assessed the prevalence and determinants of discordant treatment responses in a Rwandan cohort. Methods A discordant immunological cART response was defined as an increase of health facilities in two regions in Rwanda. Results Among 382 patients with an undetectable VL at 12 months, 112 (29%) had a CD4 rise of travel to the clinic were independent determinants of an immunological discordant response, but sex, baseline CD4 count, body mass index and WHO HIV clinical stage were not. Among 326 patients with a CD4 rise of ≥100 cells/mm3, 56 (17%) had a detectable viral load at 12 months. Male sex was associated with a virological discordant treatment response (P = 0.05), but age, baseline CD4 count, BMI, WHO HIV clinical stage, and travel time to the clinic were not. Conclusions Discordant treatment responses were common in cART-naïve HIV patients in Rwanda. Small CD4 increases could be misinterpreted as a (virological) treatment failure and lead to unnecessary treatment changes. PMID:27438000

    Full Text Available BACKGROUND: Since establishment of Zimbabwe's National Antiretroviral Therapy (ART Programme in 2004, ART provision has expanded from <5,000 to 369,431 adults by 2011. However, patient outcomes are unexplored. OBJECTIVE: To determine improvement in health status, retention and factors associated with attrition among HIV-infected patients on ART. METHODS: A retrospective review of abstracted patient records of adults ≥ 15 years who initiated ART from 2007 to 2009 was done. Frequencies and medians were calculated for rates of retention in care and changes in key health status outcomes at 6, 12, 24 and 36 months respectively. Cox proportional hazards models were used to determine factors associated with attrition. RESULTS: Of the 3,919 patients, 64% were female, 86% were either WHO clinical stage III or IV. Rates of patient retention at 6, 12, 24 and 36 months were 90.7%, 78.1%, 68.8% and 64.4%, respectively. After ART initiation, median weight gains at 6, 12, and 24 months were 3, 4.5, and 5.0 kgs whilst median CD4+ cell count gains at 6, 12 and 24 months were 122, 157 and 279 cells/µL respectively. Factors associated with an increased risk of attrition included male gender (AHR 1.2; 95% CI, 1.1-1.4, baseline WHO stage IV (AHR 1.7; 95% CI, 1.1-2.6, lower baseline body weight (AHR 2.0; 95% CI, 1.4-2. 8 and accessing care from higher level healthcare facilities (AHR 3.5; 95% 1.1-11.2. CONCLUSIONS: Our findings with regard to retention as well as clinical and immunological improvements following uptake of ART, are similar to what has been found in other settings. Factors influencing attrition also mirror those found in other parts of sub-Saharan Africa. These findings suggest the need to strengthen earlier diagnosis and treatment to further improve treatment outcomes. Whilst decentralisation improves ART coverage it should be coupled with strategies aimed at improving patient retention.

OBJECTIVE: For the period 2004-2011, to describe the trends in the numbers of people living with HIV (PLHIV registered for care and their median baseline CD4 counts, disaggregated by age and sex. DESIGN: Descriptive study involving analysis of routinely captured data (year of registration, age, sex, baseline CD4 count under NACP. RESULTS: 34,882 (97% of total eligible PLHIV were included in analysis. The number registered for care has increased by over 12 times during 2004-11; with increasing numbers among females. The median baseline CD4 cell count rose from 125 in 2004 to 235 in 2011--the increase was greater among females as compared to males. However, about two-thirds still presented at CD4 cell counts less than 350. CONCLUSION: We found an increasing trend of median CD4 counts among PLHIV presenting to ART centres in Karnataka, an indicator of enhanced and early access to HIV care. Equal proportion of females and higher baseline CD4 counts among them allays any fear of differential access by gender. Despite this relative success, a substantial proportion still presented at low CD4 cell counts indicating possibly delayed HIV diagnosis and delayed linkage to HIV care. Universal HIV testing at health care facilities and strengthening early access to care are required to bridge the gap.

    Full Text Available Introduction: There is uncertainty regarding the completeness of death recording by civil registration and by health centres in South Africa. This paper aims to compare death recording by the two systems, in cohorts of South African patients receiving antiretroviral treatment (ART. Methods: Completeness of death recording was estimated using a capture–recapture approach. Six ART programmes linked their patient record systems to the vital registration system using civil identity document (ID numbers and provided data comparing the outcomes recorded in patient files and in the vital registration. Patients were excluded if they had missing/invalid IDs or had transferred to other ART programmes. Results: After exclusions, 91,548 patient records were included. Of deaths recorded in patients files after 2003, 94.0% (95% CI: 93.3–94.6% were recorded by civil registration, with completeness being significantly higher in urban areas, older adults and females. Of deaths recorded by civil registration after 2003, only 35.0% (95% CI: 34.2–35.8% were recorded in patient files, with this proportion dropping from 60% in 2004–2005 to 30% in 2010 and subsequent years. Recording of deaths in patient files was significantly higher in children and in locations within 50 km of the health centre. When the information from the two systems was combined, an estimated 96.2% of all deaths were recorded (93.5% in children and 96.2% in adults. Conclusions: South Africa's civil registration system has achieved a high level of completeness in the recording of mortality. However, the fraction of deaths recorded by health centres is low and information from patient records is insufficient by itself to evaluate levels and predictors of ART patient mortality. Previously documented improvements in ART mortality over time may be biased if based only on data from patient records.

    HIV related mutations can be associated with decreased susceptibility to antiretrovirals and treatment failures. There is scarce information about HIV mutations in persons failing HIV treatment in North of Brazil. Our aim was to evaluate evolution of HIV subtypes and mutations patterns related to antiretroviral therapy in this region. We investigated HIV resistance profile in adults failing antiretroviral regimen in Northern Brazil from January, 2004, through December, 2013. Genotype data was evaluated through Stanford University algorithm. There were 377 genotypes from different individuals to evaluate. Resistance mutations were similar to worldwide reports and related to antiretroviral exposure. Most prevalent mutations in the reverse transcriptase gene were M184V (80.1%) and K130N (40.6%). Thymidine associated mutations were more frequent in multiexperienced patients. Most common protease mutations were M46I, V82A, I54V, L90M, I84V, M46L, and L76V. Subtype B was the most prevalent (90.7%). There were differences between subtypes B and non-B mutations. We documented for the first time subtypes and patterns of HIV associated mutations in Northern Brazil. A1 subtype was identified for the first time in this area. Depending on drug regimen and how experienced the patient is, an empirical switch of a failing antiretroviral treatment could be a reasonable option.

    Full Text Available Background: Outcomes of antiretroviral treatment have been documented in both developed and developing countries. It has been reported consistently that the treatment is associated with many adverse events. However, little is known about their impact on the quality of life, clinical management, and survival in children aged less than 6 years in Uganda.Objectives: The purpose of this study was to determine the prevalence of the adverse events of antiretroviral treatment, their impact on mortality and the change in regimens prescribed to children treated at Mildway Centre in Uganda.Method: A retrospective chart review was performed for children younger than 6 years, treated since the Mildway Centre was opened in 1999. In order to achieve a larger sample, the records of children treated from January 2000 to July 2005 were included in the study. A pre-tested data collection form was used to collate socio-demographic and clinical data of the patients. These included the documented adverse events, causes of death, stage of infection, duration of treatment, regimen prescribed, year of enrolment into the treatment program, as well as whether or not they were still alive. Descriptive statistics were used in the analysis of data.Results: Of the 179 children, the majority were males and had a median age of 4 years. The majority (58.8% of children had suffered from severe immune depression since they met the WHO clinical stage III and IV, 73.8% had a baseline CD4T of less than 15%. Four regimens were prescribed to the children. The most common was a regimen containing zidovudine, lamivudine, and nevirapine (34.6%, followed by a regimen containing stavudine, lamivudine, and nevirapine (27.9%. Eleven children (6.1% had their regimen changed, of which six (54.5% were due to adverse events. The prevalence of adverse events was 8%; of the 14 documented adverse events, the most common were severe anaemia (3, vomiting (3, and skin rashes (3. After 12 months on

    Full Text Available A problem of highly active antiretroviral therapy (HAART in HIV patients is their adherence to treatment. The aim of this study was to compare the schemes adopted in the initial therapy of these treatments with their adherence, changes in HAART schemes and treatment costs. The study included patients over 16 years old, HIV positive, in treatment for more than 30 days. Adherence to HAART was calculated based on the withdrawal of the drug, which was related to the total treatment time. We evaluated how many patients changed HAART. The costs of each regimen were also estimated and related to the benefit of each treatment. 142 patients who were between 38 and 1,150 days of treatment were included (57.7% women. The schemes with lower costs, highest adherence and greater benefit were efavirenz with biovir and efavirenz with lamivudine and tenofovir. This study suggested the advantageous therapeutic regimens to start of treatment, both from the point of view of patients and the health system. This information can serve as a subsidy to clinicians in the decision of starting HAART.

    Public sector price analyses of antiretroviral (ARV) medicines can provide relevant information to detect ARV procurement procedures that do not obtain competitive market prices. Price benchmarks provide a useful tool for programme managers and policy makers to support such planning and policy measures. The aim of the study was to develop regional and global price benchmarks which can be used to analyse public-sector price variability of ARVs in low- and middle-income countries using the procurement prices of Latin America and the Caribbean (LAC) countries in 2008 as an example. We used the Global Price Reporting Mechanism (GPRM) data base, provided by the World Health Organization (WHO), for 13 LAC countries' ARV procurements to analyse the procurement prices of four first-line and three second-line ARV combinations in 2008. First, a cross-sectional analysis was conducted to compare ARV combination prices. Second, four different price 'benchmarks' were created and we estimated the additional number of patients who could have been treated in each country if the ARV combinations studied were purchased at the various reference ('benchmark') prices. Large price variations exist for first- and second-line ARV combinations between countries in the LAC region. Most countries in the LAC region could be treating between 1.17 and 3.8 times more patients if procurement prices were closer to the lowest regional generic price. For all second-line combinations, a price closer to the lowest regional innovator prices or to the global median transaction price for lower-middle-income countries would also result in treating up to nearly five times more patients. Some rational allocation of financial resources due, in part, to price benchmarking and careful planning by policy makers and programme managers can assist a country in negotiating lower ARV procurement prices and should form part of a sustainable procurement policy.

    Mattia C F Prosperi

    Full Text Available BACKGROUND: Although genotypic resistance testing (GRT is recommended to guide combination antiretroviral therapy (cART, funding and/or facilities to perform GRT may not be available in low to middle income countries. Since treatment history (TH impacts response to subsequent therapy, we investigated a set of statistical learning models to optimise cART in the absence of GRT information. METHODS AND FINDINGS: The EuResist database was used to extract 8-week and 24-week treatment change episodes (TCE with GRT and additional clinical, demographic and TH information. Random Forest (RF classification was used to predict 8- and 24-week success, defined as undetectable HIV-1 RNA, comparing nested models including (i GRT+TH and (ii TH without GRT, using multiple cross-validation and area under the receiver operating characteristic curve (AUC. Virological success was achieved in 68.2% and 68.0% of TCE at 8- and 24-weeks (n = 2,831 and 2,579, respectively. RF (i and (ii showed comparable performances, with an average (st.dev. AUC 0.77 (0.031 vs. 0.757 (0.035 at 8-weeks, 0.834 (0.027 vs. 0.821 (0.025 at 24-weeks. Sensitivity analyses, carried out on a data subset that included antiretroviral regimens commonly used in low to middle income countries, confirmed our findings. Training on subtype B and validation on non-B isolates resulted in a decline of performance for models (i and (ii. CONCLUSIONS: Treatment history-based RF prediction models are comparable to GRT-based for classification of virological outcome. These results may be relevant for therapy optimisation in areas where availability of GRT is limited. Further investigations are required in order to account for different demographics, subtypes and different therapy switching strategies.

Rates of immunologic treatment failure and regimen-switch were 14.0 and 0.6 events per 100-patient years, respectively. CONCLUSIONS: ART initiation at earlier disease stages and scale-up of co-trimoxazole among ART patients could improve outcomes. Research to determine reasons for low regimen-switch rates and increasing rates of attrition during program expansion is needed.

    SUMMARY We described levels of habitual physical activity and physical capacity in HIV patients initiating antiretroviral treatment in Ethiopia and assessed the role of HIV and nutritional indicators on these outcomes. Physical activity energy expenditure (PAEE) and activity levels were measured...... with combined heart rate and movement sensors. Physical capacity was assessed by grip strength, sleeping heart rate and heart rate economy. Grip strength data was also available from a sex- and age-matched HIV-negative reference group. Median PAEE was 27·9 (interquartile range 17·4-39·8) kJ/kg per day and mean......±s.d. grip strength was 23·6 ± 6·7 kg. Advanced HIV disease predicted reduced levels of both physical activity and capacity; e.g. each unit viral load [log(1+copies/ml)] was associated with -15% PAEE (P

We present the protocol for a demonstration study to evaluate the feasibility, acceptability, and cost of an early ART intervention for HIV-positive truck drivers along a transport corridor across South Africa, Zimbabwe, and Zambia, as part of an enhanced strategy to improve treatment adherence and retention in care. Methods and Analysis. This demonstration study would follow an observational cohort of truck drivers receiving early treatment. Our mixed methods approach includes quantitative, qualitative, and economic analyses. Key ethical and logistical issues are discussed (i.e., choice of drug regimen, recruitment of participants, and monitoring of adherence, behavioural changes, and adverse events. Conclusion. Questions specific to the design of tailored early ART programmes are amenable to operational research approaches but present substantial ethical and logistical challenges. Addressing these in demonstration projects can inform policy decisions regarding strategies to reduce health inequalities in access to HIV prevention and treatment programmes.

    Full Text Available Background: Healthcare workers are often reluctant to start combination antiretroviral therapy (ART in patients receiving tuberculosis (TB treatment because of the fear of high pill burden, immune reconstitution inflammatory syndrome, and side-effects.Object: To quantify changes in adherence to tuberculosis treatment following ART initiation.Design: A prospective observational cohort study of ART-naïve individuals with baseline CD4 count between 50 cells/mm3 and 350 cells/mm3 at start of TB treatment at a primary care clinic in Johannesburg, South Africa. Adherence to TB treatment was measured by pill count,self-report, and electronic Medication Event Monitoring System (eMEMS before and after initiation of ART.Results: ART tended to negatively affect adherence to TB treatment, with an 8% – 10% decrease in the proportion of patients adherent according to pill count and an 18% – 22% decrease in the proportion of patients adherent according to eMEMS in the first month following ART initiation, independent of the cut-off used to define adherence (90%, 95% or 100%. Reasons for non-adherence were multi factorial, and employment was the only predictor for optimal adherence (adjusted odds ratio 4.11, 95% confidence interval 1.06–16.0.Conclusion: Adherence support in the period immediately following ART initiation could optimise treatment outcomes for people living with TB and HIV.

    Migration and geographic mobility increase risk for HIV infection and may influence engagement in HIV care and adherence to antiretroviral therapy. Our goal is to use the migration-linked communities of Santo Domingo, Dominican Republic, and New York City, New York, to determine the impact of geographic mobility on HIV care engagement and adherence to treatment. In-depth interviews were conducted with HIV+Dominicans receiving antiretroviral therapy, reporting travel or migration in the past 6 months and key informants (n=45). Mobility maps, visual representations of individual migration histories, including lifetime residence(s) and all trips over the past 2 years, were generated for all HIV+ Dominicans. Data from interviews and field observation were iteratively reviewed for themes. Mobility mapping revealed five distinct mobility patterns: travel for care, work-related travel, transnational travel (nuclear family at both sites), frequent long-stay travel, and vacation. Mobility patterns, including distance, duration, and complexity, varied by motivation for travel. There were two dominant barriers to care. First, a fear of HIV-related stigma at the destination led to delays seeking care and poor adherence. Second, longer trips led to treatment interruptions due to limited medication supply (30-day maximum dictated by programs or insurers). There was a notable discordance between what patients and providers perceived as mobility-induced barriers to care and the most common barriers found in the analysis. Interventions to improve HIV care for mobile populations should consider motivation for travel and address structural barriers to engagement in care and adherence. PMID:24839872

    Efforts to expand access to HIV care and treatment often stress the importance of disclosure of HIV status to aid adherence, social support, and continued resource mobilization. We argue that an examination of disclosure processes early in the process of seeking testing and treatment can illuminate individual decisions and motivations, offering insight into potentially improving engagement in care and adherence. We report on baseline data of early HIV disclosure and nondisclosure, including reasons for and responses to disclosure from a cohort of men and women (n=949) currently accessing antiretroviral treatment in two regions of Uganda. We found early disclosures at the time of suspicion or testing positive for HIV by men and women to be largely for the purposes of emotional support and friendship. Responses to these selected disclosures were overwhelmingly positive and supportive, including assistance in accessing treatment. Nonetheless, some negative responses of worry, fear, or social ostracism did occur. Individuals deliberately chose to not disclose their status to partners, relatives, and others in their network, for reasons of privacy or not wanting to cause worry from the other person. These data demonstrate the strategic choices that individuals make early in the course of suspicion, testing, and treatment for HIV to mobilize resources and gain emotional or material support, and similarly their decisions and ability to maintain privacy regarding their status.

    Full Text Available Abstract Background Rifampicin reduces the plasma concentrations of nevirapine in human immunodeficiency virus (HIV and tuberculosis (TB co-infected patients, who are administered these drugs concomitantly. We conducted a prospective interventional study to assess the efficacy of nevirapine-containing highly active antiretroviral treatment (HAART when co-administered with rifampicin-containing antituberculosis treatment (ATT and also measured plasma nevirapine concentrations in patients receiving such a nevirapine-containing HAART regimen. Methods 63 cases included antiretroviral treatment naïve HIV-TB co-infected patients with CD4 counts less than 200 cells/mm3 started on rifampicin-containing ATT followed by nevirapine-containing HAART. In control group we included 51 HIV patients without tuberculosis and on nevirapine-containing HAART. They were assessed for clinical and immunological response at the end of 24 and 48 weeks. Plasma nevirapine concentrations were measured at days 14, 28, 42 and 180 of starting HAART. Results 97 out of 114 (85.1% patients were alive at the end of 48 weeks. The CD4 cell count showed a mean increase of 108 vs.113 cells/mm3 (p=0.83 at 24 weeks of HAART in cases and controls respectively. Overall, 58.73% patients in cases had viral loads of less than 400 copies/ml at the end of 48 weeks. The mean (± SD Nevirapine concentrations of cases and control at 14, 28, 42 and 180 days were 2.19 ± 1.49 vs. 3.27 ± 4.95 (p = 0.10, 2.78 ± 1.60 vs. 3.67 ± 3.59 (p = 0.08, 3.06 ± 3.32 vs. 4.04 ± 2.55 (p = 0.10 respectively and 3.04 μg/ml (in cases. Conclusions Good immunological and clinical response can be obtained in HIV-TB co-infected patients receiving rifampicin and nevirapine concomitantly despite somewhat lower nevirapine trough concentrations. This suggests that rifampicin-containing ATT may be co administered in resource limited setting with nevirapine-containing HAART regimen without substantial reduction in

    Background Early mortality in people initiating antiretroviral treatment (ART) in Africa remains high. Empiric TB treatment strategies aim to reduce early mortality by initiating TB treatment in individuals without clinical suspicion of TB who are at high-risk of death from undiagnosed TB. Methods Using data from 16,913 individuals starting ART under programmatic conditions, we simulated the impact of three empiric treatment strategies on mortality and incident TB: two randomized clinical trials (REMEMBER and PrOMPT) and a pragmatic approach. The main analysis assumed that 50% of early deaths and 100% of incident TB is averted in those eligible and ignored outcomes in those lost to follow up. Results The increase in individuals eligible for TB treatment under empirical TB treatment strategies ranged from 4.4% to 31.4% as compared to those started on clinical or mycobacteriological grounds. The proportion of deaths averted by empiric treatment strategies ranged from 5.5% to 25.4%. The proportion of incident TB cases averted ranged from 10.9% to 57.3%. The proportion receiving any TB treatment during the first six months of ART increased from the observed 24.0% to an estimated 27.5%, 40.4% and 51.3% under the PrOMPT, REMEMBER and pragmatic approach, respectively. Conclusion The impact of empiric TB treatment strategies depends greatly on the eligibility criteria chosen. The additional strain placed on TB treatment facilities and the relatively limited impact of some empirical TB strategies raise the question whether the benefits will outweigh the risks at population level.

    Full Text Available BACKGROUND: Antiretroviral therapy (ART is a lifesaver for individual patients treated for Human Immunodeficiency Virus (HIV and Acquired Immune Deficiency Syndrome (AIDS. Maintaining optimal adherence to antiretroviral drugs is essential for HIV infection management. This study aimed to understand the factors influencing adherence amongst ART-prescribed patients and care providers in Nepal. METHODS: A cross-sectional mixed-methods study surveying 330 ART-prescribed patients and 34 in-depth interviews with three different types of stakeholders: patients, care providers, and key people at policy level. Adherence was assessed through survey self-reporting and during the interviews. A multivariate logistic regression model was used to identify factors associated with adherence, supplemented with a thematic analysis of the interview transcripts. RESULTS: A total of 282 (85.5% respondents reported complete adherence, i.e. no missed doses in the four-weeks prior to interview. Major factors influencing adherence were: non-disclosure of HIV status (OR = 17.99, p = 0.014; alcohol use (OR = 12.89, p = 1 hour (OR = 2.84, p = 0.035. Similarly, lack of knowledge and negative perception towards ART medications also significantly affected non-adherence. Transport costs (for repeat prescription, followed by pills running out, not wanting others to notice, side-effects, and being busy were the most common reasons for non-adherence. The interviews also revealed religious or ritual obstacles, stigma and discrimination, ART-associated costs, transport problems, lack of support, and side-effects as contributing to non-adherence. CONCLUSION: Improving adherence requires a supportive environment; accessible treatment; clear instructions about regimens; and regimens tailored to individual patients' lifestyles. Healthcare workers should address some of the practical and cultural issues around ART medicine whilst policy-makers should develop

    Full Text Available Background: In many African countries, access to antiretroviral treatment (ART has been significantly scaled up over the last five years. Nevertheless, data on drug resistance mutation are scarce. The objective of the current study was to determine the predominant subtypes of HIV-1 as well as to identify baseline mutations with potential drug resistance among ART-naïve patients from Ethiopia. Methods: Genotypic drug resistance on the entire protease and partial reverse transcriptase (codons 1–335 regions of the pol gene was determined by an in-house protocol in 160 ART-naïve patients. Genotypic drug resistance was defined as the presence of one or more resistance-related mutations, as specified by the consensus of the Stanford University HIV drug resistance database (HIVDB available at http://hivdb.stanford.edu/ and the 2011 International AIDS Society (IAS mutation list (http://www.iasusa.org/resistance-mutations/. Results: A predominance of HIV-1 subtype C (98.7% was observed. According to the IAS mutation list, antiretroviral drug resistance mutations were detected in 20 patients (13%. However, the level of drug resistance is 5.2% (8/155 when the most conservative method, HIVDB algorithms were applied. In both algorithms, none had major PI mutation and mutation-conferring resistance to NRTI and NNRTI were not overlapping. Conclusions: There is strong evidence for clade homogeneity in Ethiopia and low influx of other subtypes to the country. The level of transmitted drug resistance exceeds that of WHO estimates and indicates that many HIV-infected individuals on ART are practicing risk-related behaviours. The results also show that HIV drug resistance testing should be installed in resource limited settings.

    The prospects for expanded access to antiretroviral therapy (ART) in resource-poor settings have greatly improved as a result of global and national efforts to reduce the cost of antiretroviral drugs (ARV), growing availability of cheaper generics, and increased financing available from the Global Funds like Medicines Sans Frontieres. Indian health set-up provides drugs free-of-cost to HIV infected patients through government network and also through open-market to those who intend to have personalized care. Post-2005, implementation of WTO agreement on TRIPS is expected to have a significant impact on pricing and availability of generic ARV. The study has been planned to explore the trends and gaps in availability & accessibility of ARV in India. The trends in per-patient-per-year (PPPY) cost of individual ARV and treatment regimes were also explored. The epidemiological data demonstrated stabilization of the epidemic in India. Most ARV are available in India by the generic manufacturers with a median drug lag period of 2.05 years (Range 0.75-6.51 years). There is a significant price difference in drugs available from generic and originator companies. Prices for patented and generic ARV in India reflect price negotiations that have taken place since the introduction of drugs in the country, still most of the ARVs are available at a much higher cost in the market [median 2.6 times (range 1-7)]. The per-patient per year (PPPY) cost of providing first-line regime in 2008 has decreased 2.75 times from that in 2003. The analysis shows the stabilization of prices of all drugs after 2006. HIV spending in India has seen a growth of 26 percent and 28 percent in 2005-06 and 2006-07 respectively. Still, the expected expenditure to cover the whole patient population needing therapy is considerably higher than the actual expenditure incurred for providing ARV. Despite the price reductions and availability of ARV at a lower cost through agencies like MSF, there is a large gap

    Treatment adherence to Highly Active Antiretroviral Therapy (HAART) is a critical issue in human immunodeficiency virus (HIV) care. HAART can extend the longevity of people living with HIV, but treatment efficacy relies on strict adherence that is difficult for many consumers to manage. Results presented in this article are based on semi-structured in-depth interviews with Native Hawaiian consumers (n = 6) who reported moderate to low levels of overall HAART adherence, and based on their kokua, or primary support. All interviews were recorded on audiotape, transcribed verbatim, and analyzed using Grounded Theory methods. Research questions that guided the inquiry, included: What are the challenges of Hawaiians who report moderate to low levels of HAART adherence? How does non-adherence occur? What is the role of the kokua (primary caregiver) and/or family members in treatment adherence? What types of support enhance adherence? The unpredictability of living with HIV was a major challenge to adherence. Symptom distress and active use of alcohol and other drugs interfered with the capacity to appropriately adhere. Two patterns of non-adherence were identified: interrupted regime and intermittent use. Tangible and emotional types of support, sometimes delivered in culture-specific ways, were viewed as helpful in maintaining compliance and in resuming the regime when difficulties arose. The findings complement extant research on HAART by providing an understanding of adherence as a lived experience among Native Hawaiians and their kokua. PMID:12180508

    The aim of the present study was to explore the treatment effect of tenofovir as implemented in clinical practice. Data are presented on 34 patients. 11 patients had tenofovir added to a stable anti-retroviral treatment (ART) and 23 patients had drugs other than tenofovir. CD4 counts, HIV......-RNA levels and genotypic resistance were determined at baseline and after 3 and 6 months. After initiation of tenofovir treatment, a mean decrease in HIV-RNA for all 34 patients was observed (-0.43 log1o copies/ml (+/- 1.22) and -0.49 log10 copies/ml (+/- 1.36) after 3 and 6 months, respectively, (p = 0.......045)). However, the effect of tenofovir on HIV-RNA in the group of patients who had tenofovir added to a stable ART was limited, and the decrease in HIV-RNA was significantly higher in patients who had drugs other than tenofovir changed as well (p = 0.004 and p = 0.03 after 3 and 6 months, respectively).

    Full Text Available Abstract Background Serum concentrations of soluble urokinase-type plasminogen activator receptor (suPAR have a strong independent association with HIV-1-related mortality. The practical utility of plasma suPAR in assessing short-term all-cause mortality risk was evaluated in patients with advanced immunodeficiency enrolling in an antiretroviral treatment (ART programme in South Africa. Methods An enzyme-linked immunosorbent assay (ELISA was used to measure plasma concentrations of suPAR in patients at the time of enrolment to the ART programme. The association between plasma suPAR concentrations, baseline patient characteristics and cohort outcomes after 4 months of ART were determined. Results Patients (n = 293, 70% female had a median age of 33 years and were followed up for a median of 5 months from enrolment. The median CD4 cell count was 47 cells/μl (IQR = 22–72 and 38% of patients had WHO stage 4 disease. 218 (74% patients remained alive after 4 months of ART; 39 (13% died and 36 (12% were lost to the programme for other reasons. Patients who died had significantly higher plasma suPAR concentrations compared to those who either survived (P 10 suPAR concentrations were significantly associated with lower CD4 cell counts, WHO clinical stage 4 disease and male sex. In multivariate analysis to identify factors associated with death, log10 suPAR concentration was the most strongly associated variable (P Conclusion Plasma suPAR concentration was the strongest independent predictor of short-term mortality risk among patients with advanced immunodeficiency enrolling in this ART programme. However, lack of a discriminatory threshold did not permit this marker to be used to triage patients according to short-term mortality risk.

    Since the appearance of crack cocaine in the 1980s, unprecedented numbers of women have become addicted. A disproportionate number of female crack users are Black and poor. We analyzed interview data of HIV-infected women > or = 18 years of age reported to 12 health departments between July 1997 and December 2000 to ascertain if Black women reported crack use more than other HIV-infected women and to examine the relationship between crack use and antiretroviral treatment (ART) adherence among Black women. Of 1655 HIV-infected women, 585 (35%) were nonusers of drugs, 694 (42%) were users of other drugs and 376 (23%) were crack users. Of the 1196 (72%) Black women, 306 (26%) were crack users. We used logistic regression to examine the effect of crack use on adherence to ART, controlling for age and education among Black women. In multivariate analysis, crack users and users of other drugs were less likely than non-users to take their ART medicines exactly as prescribed (odds ratio [OR] = 0.37; 95% confidence interval [CI] = 0.24-0.56), OR = 0.47; 95% CI = 0.36-0.68), respectively. HIV-infected Black women substance users, especially crack cocaine users, may require sustained treatment and counseling to help them reduce substance use and adhere to ART.

    The discovery of the human immunodeficiency virus (HIV) as the causative organism of acquired immunodeficiency syndrome (AIDS) and the inability of modern medicine to find a cure for it has placed HIV as one of the most dreaded pathogens of the 21(st) century. With millions of people infected with HIV, it was once thought to result in "medical apocalypse". However, with the advent of antiretroviral therapy (ART), it is now possible to control HIV. Adherence to ART helps to keep the viral load under control and prolong the time of progression to AIDS, resulting in near normal life expectancy. Even with the introduction of ART, a substantial number of patients fail to adhere due to a variety of reasons, including adverse side effects, drug abuse, mental disorders, socioeconomic status, literacy, and social stigma. With the availability of so many options for HIV treatment at each stage of the disease progression, physicians can switch between the treatment regimens to avoid and/or minimize the adverse effects of drugs. Close monitoring, major social reforms, and adequate counselling should also be implemented to circumvent other challenges.

    Background. The optimal treatment of malaria in human immunodeficiency virus (HIV)–infected children requires consideration of critical drug–drug interactions in coinfected children, as these may significantly impact drug exposure and clinical outcomes. Methods. We conducted an intensive and sparse pharmacokinetic/pharmacodynamic study in Uganda of the most widely adopted artemisinin-based combination therapy, artemether-lumefantrine. HIV-infected children on 3 different first-line antiretroviral therapy (ART) regimens were compared to HIV-uninfected children not on ART, all of whom required treatment for Plasmodium falciparum malaria. Pharmacokinetic sampling for artemether, dihydroartemisinin, and lumefantrine exposure was conducted through day 21, and associations between drug exposure and outcomes through day 42 were investigated. Results. One hundred forty-five and 225 children were included in the intensive and sparse pharmacokinetic analyses, respectively. Compared with no ART, efavirenz (EFV) reduced exposure to all antimalarial components by 2.1- to 3.4-fold; lopinavir/ritonavir (LPV/r) increased lumefantrine exposure by 2.1-fold; and nevirapine reduced artemether exposure only. Day 7 concentrations of lumefantrine were 10-fold lower in children on EFV vs LPV/r-based ART, changes that were associated with an approximate 4-fold higher odds of recurrent malaria by day 28 in those on EFV vs LPV/r-based ART. Conclusions. The choice of ART in children living in a malaria-endemic region has highly significant impacts on the pharmacokinetics and pharmacodynamics of artemether-lumefantrine treatment. EFV-based ART reduces all antimalarial components and is associated with the highest risk of recurrent malaria following treatment. For those on EFV, close clinical follow-up for recurrent malaria following artemether-lumefantrine treatment, along with the study of modified dosing regimens that provide higher exposure, is warranted.

    Full Text Available BACKGROUND: There are approximately 3 million people aged 50 and older in sub-Saharan Africa who are HIV-positive. Despite this, little is known about the characteristics of older adults who are on treatment and their treatment outcomes. METHODS: A retrospective cohort analysis was performed using routinely collected data with Malawi Ministry of Health monitoring tools from facilities providing antiretroviral therapy services in Zomba district. Patients aged 25 years and older initiated on treatment from July 2005 to June 2010 were included. Differences in survival, by age group, were determined using Kaplan-Meier survival plots and Cox proportional hazards regression models. RESULTS: There were 10,888 patients aged 25 and older. Patients aged 50 and older (N = 1419 were more likely to be male (P<0.0001 and located in rural areas (P = 0.003 than those aged 25-49. Crude survival estimates among those aged 50-59 were not statistically different from those aged 25-49 (P = 0.925. However, survival among those aged 60 and older (N = 345 was worse (P = 0.019 than among those 25-59. In the proportional hazards model, after controlling for sex and stage at initiation, survival in those aged 50-59 did not differ significantly from those aged 25-49 (hazard ratio 1.00 (95% CI: 0.79 to 1.27; P = 0.998 but the hazard ratio was 1.46 (95% CI: 1.03 to 2.06; P = 0.032 for those aged 60 and older compared to those aged 25-49. CONCLUSIONS: Treatment outcomes of those aged 50-59 are similar to those aged 25-49. A better understanding of how older adults present for and respond to treatment is critical to improving HIV services.

    The examination of antibody responses in human immunodeficiency virus (HIV)-1-infected individuals in the setting of antiretroviral treatment (ART) interruption can provide insight into the evolution of antibody responses during viral rebound. In this study, we assessed antibody responses in 20 subjects in AIDS Clinical Trials Group A5187, wherein subjects were treated with antiretroviral therapy during acute/early HIV-1 infection, underwent analytic treatment interruption, and subsequently demonstrated viral rebound. Our data suggest that early initiation of ART arrests the maturation of HIV-1-specific antibody responses, preventing epitope diversification of antibody binding and the development of functional neutralizing capacity. Antibody responses do not appear permanently blunted, however, because viral rebound triggered the resumption of antibody maturation in our study. We also found that antibody responses measured by these assays did not predict imminent viral rebound. These data have important implications for the HIV-1 vaccine and eradication fields.

    Full Text Available The use of highly active antiretroviral therapy (HAART in HIV-infected patients has been associated with the development of risk factors for cardiovascular diseases (CD including dyslipidemia and insulin resistance, hypertriglyceridemia being the most frequent metabolic disturbance in these patients. Fibrates are indicated when hypertriglyceridemia is accentuated and persists for over six months. We evaluated the efficacy and safety of bezafibrate for the treatment of hypertriglyceridemia in HIV-infected individuals on HAART. All patients received 400mg/day of bezafibrate and were evaluated three times: Mo (pre-treatment, M1 (one month after treatment, and M2 (six months after treatment. Fifteen adult individuals, eight males and seven females with mean age = 41.2 ± 7.97 years and triglyceride serum levels > 400mg/dL were included in the study. Smoking, alcohol ingestion and sedentarism rates were 50%, 6.66% and 60%, respectively. Family history of CD, hypertension and diabetes mellitus was reported in 33.3%, 40% and 46.7% of the cases, respectively, while dyslipidemia was reported by only 13.3%. More than half of the patients were using a protease inhibitor plus a nucleotide analog transcriptase inhibitor. Eutrophy and tendency toward overweight were observed at all three study time points. There were significant reductions in triglyceride serum levels from Mo to M1 and from Mo to M2. No significant changes were observed in the serum levels of creatine phosphokinase, hepatic enzymes, CD4+, CD8+ and viral load. Therefore, bezafibrate seems to be safe and effective for the reduction of hypertriglyceridemia in HIV-infected patients on HAART.

    Full Text Available BACKGROUND: HIV/AIDS affects all sectors of the population and the defence forces are not exempt. A national survey was conducted in all public and private sectors in Malawi that provide antiretroviral therapy (ART to determine the uptake of ART by army personnel, their outcomes while on treatment, and the impact of ART on mortality in the Malawi Defence Force. METHODOLOGY/PRINCIPAL FINDINGS: A retrospective cohort analysis was carried out, collecting data on access and retention on treatment from all 103 public and 38 private sector ART clinics in Malawi, using standardised patient master cards and clinic registers. Observations were censored on December 31(st 2006. Independent data on mortality trends in army personnel from all causes between 2002 and 2006 were available from army records. By December 31(st 2006, there were 85,168 patients ever started on ART in both public and private sectors, of whom 547 (0.7% were army personnel. Of these, 22% started ART in WHO clinical stage 1 or 2 with a CD4-lymphocyte count of Treatment outcomes of army personnel by December 31(st 2006 were:-365 (67% alive and on ART at their registration facility, 98 (18% transferred out to another facility, 71 (13% dead, 9 (2% lost to follow-up, and 4 (<1% stopped treatment. The probability of being alive on ART at 6-, 12- and 18-months was 89.8%, 83.4% and 78.8% respectively. All-cause mortality in army personnel declined dramatically over the five year period from 2002-2006. CONCLUSION/SIGNIFICANCE: There has been a good access of army personnel to ART during the last five years with excellent outcomes, and this should serve as an example for other defence forces and large companies in the region.

    Full Text Available Background & objectives: National Anti-retroviral treatment (ART programme in India was launched in 2004. Since then, there has been no published country representative estimate of suboptimal adherence among people living with HIV (PLHIV on first line ART in public settings. Hence a multicentric study was undertaken in 15 States of India to assess the level of suboptimal adherence and its determinants among PLHIV. Methods: Using a prospective observational study design, 3285 PLHIV were enrolled and followed up to six months across 30 ART centres in India. Adherence was assessed using pill count and self-reported recall method and determinants of suboptimal adherence were explored based on the responses to various issues as perceived by them. Results: Suboptimal adherence was found in 24.5 per cent PLHIV. Determinants of suboptimal adherence were illiteracy (OR-1.341, CI-1.080-1.665 , on ART for less than 6 months (OR-1.540, CI- 1.280-1.853, male gender (OR for females -0.807, CI- 0.662-0.982, tribals (OR-2.246, CI-1.134-4.447, on efavirenz (EFA regimen (OR- 1.479, CI - 1.190 - 1.837, presence of anxiety (OR- 1.375, CI - 1.117 - 1.692, non-disclosure of HIV status to family (OR- 1.549, CI - 1.176 - 2.039, not motivated for treatment (OR- 1.389, CI - 1.093 - 1.756, neglect from friends (OR-1.368, CI-1.069-1.751, frequent change of residence (OR- 3.373, CI - 2.659 - 4.278, travel expenses (OR- 1.364, CI - 1.138-1.649, not meeting the PLHIV volunteer/community care coordinator at the ART center (OR-1.639, CI-1.330-2.019. Interpretation & conclusions: To enhance identification of PLHIV vulnerable to suboptimal adherence, the existing checklist to identify the barriers to adherence in the National ART Guidelines needs to be updated based on the study findings. Quality of comprehensive adherence support services needs to be improved coupled with vigilant monitoring of adherence measurement.

    Primary HIV-1 infection causes extensive immune activation, during which CD4+ T cell activation supports massive HIV-1 production. We tested the safety and the immune-modulating effects of combining cyclosporin A (CsA) treatment with highly active antiretroviral therapy (HAART) during primary HIV-1 infection. Nine adults with primary HIV-1 infection were treated with CsA along with HAART. At week 8, all patients discontinued CsA but maintained HAART. Viral replication was suppressed to a comparable extent in the CsA + HAART cohort and in 29 control patients whose primary infection was treated with HAART alone. CsA restored normal CD4+ T cell levels, both in terms of percentage and absolute numbers. The increase in CD4+ T cells was apparent within a week and persisted throughout the study period. CsA was not detrimental to virus-specific CD8+ or CD4+ T cell responses. At week 48, the proportion of IFN-γ–secreting CD4+ and CD4+CCR7– T cells was significantly higher in the CsA + HAART cohort than in the HAART-alone cohort. In conclusion, rapid shutdown of T cell activation in the early phases of primary HIV-1 infection can have long-term beneficial effects and establish a more favorable immunologic set-point. Appropriate, immune-based therapeutic interventions may represent a valuable complement to HAART for treating HIV infection. PMID:11877476

    Full Text Available The much-used phrase ‘prevention is better than cure’ is applicable to many circumstances, including human immunodeficiency virus (HIV infection. In recent years suggestions have been made for a move towards treatment strategies that emphasise prevention of foreseeable adherence problems on a patient-by-patient basis, through focused patient preparation before commencing antiretroviral therapy (ART. This is well elucidated in a statement made in 2004 by Coetzee et al.:1 ‘As it is difficult to ascertain robust predictors of adherence, there has been a move to concentrate on patient preparation before the initiation of ART rather than the use of non-clinical predictors of adherence or selection criteria. A paradigm focused on preparation rather than selection is better suited to the aggressive targets for the scaling up of ART in countries with large epidemics (such as in South Africa, where the view of ART as a very expensive rationed intervention is rapidly changing.’

    Full Text Available Introduction: Antiretroviral drugs in Spain are delivered by law only in hospital pharmacies. Commercial packages meet variable quality standards when dispensed drugs are returned due to treatment changes or adherence problems Nearly 20–25% of the initial regimens will be changed at 48 weeks for different reasons. We evaluated the economic impact on public health system of the inability of using returned drugs due to inefficient packaging. Materials and Methods: We defined socially efficient packaging as the best adapted one to being delivered in unit dose to outpatients and classified: Class A - Drug packed in unit doses with complete info (name of drug, dosage in mg, lot, and expiring date in each unit, maintaining complete information of the drug if returned when the external package is opened. Class B - packed in blisters with complete info in the blister, but not in unit doses, without special conservation conditions (should be re-packed in unit doses in the pharmacy before its dispensation to assure a class A excellence. Class C - packed in plastic containers with complete info written only on a label over the container, would allow repackaging only before its initial delivery, but not when returned. Class D - drug packed in plastic containers with manufacturer's warning that the product cannot be placed outside of the original package due to special conditions of conservation (fridge, humidity that doesn’t allow a unit dose repackaging or reusing an opened container. We analysed a 12-month period (July 2011–June 2012 in a hospital-based HIV outpatient pharmacy that serves 2413 treated individuals. Results: Patients generated 23,574 visits to pharmacy, and received 48,325 drug packages, with 2.529.137 pills delivered. The patients suffered 1051 treatment changes for any reason. A total amount of 122.945€ in treatment were returned to pharmacy in opened packages during the study period. 47.139.91€ would be totally lost, mainly due

    India's National AIDS Control Organization (NACO) provides free first-line antiretroviral treatment (ART) at government centers for people living with HIV. To assist in developing policies and programs to ensure equity in ART access, we explored barriers to ART access among female sex workers (FSWs) living with HIV in Chennai. Between August and November 2007, we conducted three focus group discussions and two key informant interviews. Data were explored using framework analysis to identify categories and derive themes. We found interrelated barriers at the family/social, health care system/programmatic, and individual levels. Major barriers included fear of adverse consequences of disclosure of HIV status due to stigma and discrimination associated with HIV and sex work, lack of family support, negative experiences with health care providers, lack of adequate counseling services at government centers and by outreach workers employed by nongovernmental organizations (NGOs), perceived biased treatment of FSWs who are not referred by NGOs, lack of adequate knowledge about ART, and fatalism. Barriers can be addressed by: creating effective measures to reduce stigma associated with HIV/AIDS and sex work at the familial, societal, and health care system levels; incorporating information about ART into targeted interventions among FSWs; training counselors at government hospitals and NGO outreach workers on treatment issues; improving infrastructure and staffing levels at government centers to allow adequate time and privacy for counseling; and implementing government mass media campaigns on ART availability. Finally, it is crucial that NACO begin monitoring ART coverage of FSWs and other marginalized populations to ensure equitable ART access. PMID:19821725

  15. HIV treatment as prevention: modelling the cost of antiretroviral treatment--state of the art and future directions.

    Gesine Meyer-Rath

    Full Text Available Policy discussions about the feasibility of massively scaling up antiretroviral therapy (ART to reduce HIV transmission and incidence hinge on accurately projecting the cost of such scale-up in comparison to the benefits from reduced HIV incidence and mortality. We review the available literature on modelled estimates of the cost of providing ART to different populations around the world, and suggest alternative methods of characterising cost when modelling several decades into the future. In past economic analyses of ART provision, costs were often assumed to vary by disease stage and treatment regimen, but for treatment as prevention, in particular, most analyses assume a uniform cost per patient. This approach disregards variables that can affect unit cost, such as differences in factor prices (i.e., the prices of supplies and services and the scale and scope of operations (i.e., the sizes and types of facilities providing ART. We discuss several of these variables, and then present a worked example of a flexible cost function used to determine the effect of scale on the cost of a proposed scale-up of treatment as prevention in South Africa. Adjusting previously estimated costs of universal testing and treatment in South Africa for diseconomies of small scale, i.e., more patients being treated in smaller facilities, adds 42% to the expected future cost of the intervention.

    Full Text Available BACKGROUND: Retaining patients with HIV infection in care is still a major challenge in sub- Saharan Africa, particularly in the Democratic Republic of Congo (DRC where the antiretroviral treatment (ART coverage is low. Monitoring retention is an important tool for evaluating the quality of care. METHODS AND FINDINGS: A review of medical records of HIV-infected children was performed in three health facilities in the DRC: the Amo-Congo Health center, the Monkole Clinic in Kinshasa, and the HEAL Africa Clinic in Goma. Medical records of 720 children were included. Kaplan Meier curves were constructed with the probability of retention at 6 months, 1 year, 2 years and 3 years. Retention rates were: 88.2% (95% CI: 85.1%-90.8% at 6 months; 85% (95% CI: 81.5%-87.6% at one year; 79.4% (95%CI: 75.5%-82.8% at two years and 74.7% (95% CI: 70.5%-78.5% at 3 years. The retention varied across study sites: 88.2%, 66.6% and 92.5% at 6 months; 84%, 59% and 90% at 12 months and 75.7%, 56.3% and 85.8% at 24 months respectively for Amo-Congo/Kasavubu, Monkole facility and HEAL Africa. After multivariable Cox regression four variables remained independently associated with attrition: study site, CD4 cell count <350 cells/µL, children younger than 2 years and children whose caregivers were member of an independent church. CONCLUSIONS: Attrition remains a challenge for pediatric HIV positive patients in ART programs in DRC. In addition, the low coverage of pediatric treatment exacerbates the situation of pediatric HIV/AIDS.

    Full Text Available Abstract Background To identify the determinants of successful antiretroviral (ARV therapy, researchers study the virological responses to treatment-change episodes (TCEs accompanied by baseline plasma HIV-1 RNA levels, CD4+ T lymphocyte counts, and genotypic resistance data. Such studies, however, often differ in their inclusion and virological response criteria making direct comparisons of study results problematic. Moreover, the absence of a standard method for representing the data comprising a TCE makes it difficult to apply uniform criteria in the analysis of published studies of TCEs. Results To facilitate data sharing for TCE analyses, we developed an XML (Extensible Markup Language Schema that represents the temporal relationship between plasma HIV-1 RNA levels, CD4 counts and genotypic drug resistance data surrounding an ARV treatment change. To demonstrate the adaptability of the TCE XML Schema to different clinical environments, we collaborate with four clinics to create a public repository of about 1,500 TCEs. Despite the nascent state of this TCE XML Repository, we were able to perform an analysis that generated a novel hypothesis pertaining to the optimal use of second-line therapies in resource-limited settings. We also developed an online program (TCE Finder for searching the TCE XML Repository and another program (TCE Viewer for generating a graphical depiction of a TCE from a TCE XML Schema document. Conclusions The TCE Suite of applications – the XML Schema, Viewer, Finder, and Repository – addresses several major needs in the analysis of the predictors of virological response to ARV therapy. The TCE XML Schema and Viewer facilitate sharing data comprising a TCE. The TCE Repository, the only publicly available collection of TCEs, and the TCE Finder can be used for testing the predictive value of genotypic resistance interpretation systems and potentially for generating and testing novel hypotheses pertaining to the

    Full Text Available BACKGROUND: Smear-positive pulmonary TB is the most infectious form of TB. Previous studies on the effect of HIV and antiretroviral therapy on TB treatment outcomes among these highly infectious patients demonstrated conflicting results, reducing understanding of important issues. METHODS: All adult smear-positive pulmonary TB patients diagnosed between 2008 and 2010 in Malawi's largest public, integrated TB/HIV clinic were included in the study to assess treatment outcomes by HIV and antiretroviral therapy status using logistic regression. RESULTS: Of 2,361 new smear-positive pulmonary TB patients, 86% had successful treatment outcome (were cured or completed treatment, 5% died, 6% were lost to follow-up, 1% failed treatment, and 2% transferred-out. Overall HIV prevalence was 56%. After adjusting for gender, age and TB registration year, treatment success was higher among HIV-negative than HIV-positive patients (adjusted odds ratio 1.49; 95% CI: 1.14-1.94. Of 1,275 HIV-infected pulmonary TB patients, 492 (38% received antiretroviral therapy during the study. Pulmonary TB patients on antiretroviral therapy were more likely to have successful treatment outcomes than those not on ART (adjusted odds ratio : 1.83; 95% CI: 1.29-2.60. CONCLUSION: HIV co-infection was associated with poor TB treatment outcomes. Despite high HIV prevalence and the integrated TB/HIV setting, only a minority of patients started antiretroviral therapy. Intensified patient education and provider training on the benefits of antiretroviral therapy could increase antiretroviral therapy uptake and improve TB treatment success among these most infectious patients.

    The treatment of obesity is an often studied subject. Although reductions in weight and improvements in cardiometabolic risk factors are important aims of obesity treatment, improvements in quality of life and eating behaviour are also relevant outcomes. In this practice-based study, we evaluated an 18-month commercial multidisciplinary obesity treatment programme and report on treatment results for weight, cardiometabolic risk factors, eating behaviour and quality of life. From a local commercial obesity treatment centre, 426 subjects (65% female; 45.4 ± 12.2 years; body mass index 40.0 ± 6.6 kg m(-2)) were recruited. Measurements of body weight, height, body composition, waist circumference and blood pressure were scheduled at baseline and every 3 months, whereas fasting blood collections were scheduled at baseline and every 6 months. At the same time points, participants were asked to fill in questionnaires on dietary intake, eating behaviour and quality of life. After 18 months of treatment programme, average weight change [mean (95% confidence interval)] was -10.9 kg (-14.8 to -7.0; P < 0.001) for the completers (n = 181) and -10.8 kg (-14.2 to -7.4; P < 0.001) for the intention-to-treat population (n = 426). Waist circumference (mean ± standard error of the mean) (-0.13 ± 0.01 cm; P < 0.001), fat mass (-7.8 ± 1.3 kg; P < 0.001) systolic (-11.4 ± 2.0; P < 0.001) and diastolic (-7.0 ± 1.3; P < 0.001) blood pressure, triglycerides (-0.4 ± 0.1; P = 0.004) and plasma glucose (-0.6 ± 0.2; P = 0.001) were significantly reduced. The PCS scale of the SF-36 and all three scales of the three-factor eating questionnaire improved significantly over the 18-month treatment period. All collected data in this study provide evidence that a multidisciplinary treatment programme based on lifestyle modification results in significant weight loss and improvements in cardiometabolic

    Full Text Available Commencement of antiretroviral treatment (ART in severely immunosuppressed HIV-infected persons is associated with unmasking of subclinical disease. The subset of patients that are diagnosed with tuberculosis (TB disease while on ART have been classified as ART-associated TB. Few studies have reported the incidence of ART-associated TB and unmasking TB-IRIS according to the International Network for the Study of HIV-Associated IRIS (INSHI consensus definition. To determine the incidence and predictors of ART-associated TB, we screened 219 patients commencing ART at the Infectious Diseases Clinic in Kampala, Uganda for TB by symptoms, sputum microscopy, and chest X-rays and followed them for one year. Fourteen (6.4% patients were diagnosed with TB during followup. Eight (3.8% patients had ART-associated TB (incidence rate of 4.3 per 100 person years; of these, three patients fulfilled INSHI criteria for unmasking TB-associated IRIS (incidence rate of 1.6 per 100 person years. A body mass index of less than 18.5 kg/m2 BMI (HR 5.85 95% CI 1.24–27.46, P=.025 and a C-reactive protein greater than 5 mg/L (HR 8.23 95% CI 1.36–38.33, P=.020 were risk factors for ART-associated TB at multivariate analysis. In conclusion, with systematic TB screening (including culture and chest X-ray, the incidence of ART-associated TB is relatively low in settings with high HIV and TB prevalence.

    Full Text Available Aims: To assess the functional status of patients with Acquired immunodeficiency syndrome (AIDS registered in the Anti-Retroviral Treatment (ART center. Materials and Methods: Design: Descriptive study. Study setting: ART center in Calicut Medical College, Kerala, India. Subjects: Cohorts of AIDS patients attending the ART center during the year 2007. Data collection: Done prospectively from the secondary data available from the center. Outcome measures: The demographic, morbidity, functional status and laboratory parameters were collected. Data processing was done using Excel datasheet and analysis were done using Epi info 2003. Results: One hundred and ninety-five patients received care during this period; 69% were males. The mean age was 38±9 years; 80% of them were married and in 50% of their spouses also tested positive for HIV. The mean CD4 count was 127 cells/microliter. The majority (90% were categorized as WHO Stage 3 or 4 of HIV. Only 52% of them were able to perform their usual work in or outside their house; the rest were not able to lead an economically productive life. Thirty-six per cent were only able to perform activities of daily living; 12% were bedridden.The functional status of the patients positively correlated with WHO disease stage ( P = < 0-0001, and CD4 count and hemoglobin levels negatively correlated with staging ( P = < 0.001. 62% are having any of the opportunistic infections. Conclusion: Fifty per cent of the AIDS patients are disabled and need support and care. As AIDS is a growing problem, community-based palliative care for AIDS patients should be strengthened in India.

    Emma Rosamond Nony Weaver

    Full Text Available Although the number of people receiving antiretroviral therapy (ART in Indonesia has increased in recent years, little is known about the specific characteristics affecting adherence in this population. Indonesia is different from most of its neighbors given that it is a geographically and culturally diverse country, with a large Muslim population. We aimed to identify the current rate of adherence and explore factors that influence ART adherence.Data were collected from ART-prescribed outpatients on an HIV registry at a North Jakarta hospital in 2012. Socio-demographic and behavioral characteristics were explored as factors associated with adherence using logistics regression analyses. Chi squared test was used to compare the difference between proportions. Reasons for missing medication were analyzed descriptively.Two hundred and sixty-one patients participated, of whom 77% reported ART adherence in the last 3 months. The level of social support experienced was independently associated with adherence where some social support (p = 0.018 and good social support (p = 0.039 improved adherence compared to poor social support. Frequently cited reasons for not taking ART medication included forgetting to take medication (67%, busy with something else (63% and asleep at medication time (60%.This study identified that an increase in the level of social support experienced by ART-prescribed patients was positively associated with adherence. Social support may minimize the impact of stigma among ART prescribed patients. Based on these findings, if social support is not available, alternative support through community-based organizations is recommended to maximize treatment success.

    2009-02-01

    Full Text Available Abstract Background Since the beginning of the 21st century, development assistance for HIV/AIDS has increasingly been provided through Global Health Initiatives, specifically the United States Presidential Emergency Plan for AIDS Relief, the Global Fund to Fight HIV, TB and Malaria and the World Bank Multi-country AIDS Programme. Zambia, like many of the countries heavily affected by HIV/AIDS in southern Africa, also faces a shortage of human resources for health. The country receives significant amounts of funding from GHIs for the large-scale provision of antiretroviral treatment through the public and private sector. This paper examines the impact of GHIs on human resources for ART roll-out in Zambia, at national level, in one province and two districts. Methods It is a qualitative policy analysis relying on in-depth interviews with more than 90 policy-makers and implementers at all levels. Results Findings show that while GHIs do not provide significant funding for additional human resources, their interventions have significant impact on human resources for health at all levels. While GHIs successfully retrain a large number of health workers, evidence suggests that GHIs actively deplete the pool of skilled human resources for health by recruiting public sector staff to work for GHI-funded nongovernmental implementing agencies. The secondment of GHI staff into public sector facilities may help alleviate immediate staff shortages, but this practice risks undermining sustainability of programmes. GHI-supported programmes and initiatives add significantly to the workload of existing public sector staff at all levels, while incentives including salary top-ups and overtime payments mean that ART programmes are more popular among staff than services for non-focal diseases. Conclusion Research findings suggest that GHIs need to actively mediate against the potentially negative consequences of their funding on human resources for health. Evidence

  5. The occurrence of anti-retroviral compounds used for HIV treatment in South African surface water

    International Nuclear Information System (INIS)

    The study and quantification of personal care products, such as pharmaceuticals, in surface water has become popular in recent years; yet very little description of these compounds’ presence in South African surface water exists in the literature. Antiretrovirals (ARVs), used to treat human immunodeficiency virus (HIV) are rarely considered within this field. A new method for the simultaneous quantification of 12 antiretroviral compounds in surface water using the standard addition method is described. Water samples were concentrated by a generic automated solid phase extraction method and analysed by ultra-high pressure liquid chromatography tandem mass spectrometry (UHPLC-MS/MS). Substantial matrix effect was encountered in the samples with an average method detection limit of 90.4 ng/L. This is the first reported countrywide survey of South African surface water for the quantification of these compounds with average concentrations ranging between 26.5 and 430 ng/L. - Highlights: • An LC-MS/MS method for the detection of 12 antiretroviral drugs was developed. • The compounds were detected in South African surface water for the first time. • Targets occurred in the low to mid ng/L range. • Nevirapine occurred ubiquitously across all the samples tested. • Matrix effect was corrected for using a modified standard addition method. - This work represents the first quantitative description of anti-retrovirals, as a group, in surface water using a modified standard addition method and UHPLC-MS/MS

    Full Text Available Objective: To assess the effects of facility-based interventions using existing resources to improve overall patient attendance and adherence to antiretroviral therapy (ART at ART-providing facilities in Uganda. Methods: This was an interventional study which tracked attendance and treatment adherence of two distinct cohorts: experienced patients who had been on treatment for at least 12 months prior to the intervention and patients newly initiated on ART before or during the intervention. The interventions included instituting appointment system, fast-tracking, and giving longer prescriptions to experienced stable patients. Mixed-effects models were used to examine intervention effects on the experienced patients, while Cox proportional hazards models were used to determine the intervention effects on time until newly treated patients experienced gaps in medication availability. Results: In all, 1481 patients’ files were selected for follow-up from six facilities – 720 into the experienced cohort, and 761 into the newly treated cohort. Among patients in the experienced cohort, the interventions were associated with a significant reduction from 24.4 to 20.3% of missed appointments (adjusted odds ratio (AOR: 0.67; 95% confidence interval (CI: 0.59–0.77; a significant decrease from 20.2 to 18.4% in the medication gaps of three or more days (AOR: 0.69; 95% CI: 0.60–0.79; and a significant increase from 4.3 to 9.3% in the proportion of patients receiving more than 30 days of dispensed medication (AOR: 2.35; 95% CI: 1.91–2.89. Among newly treated patients, the interventions were associated with significant reductions of 44% (adjusted hazard rate (AHR: 0.56, 95% CI: 0.42–0.74 and 38% (AHR: 0.62; 95% CI: 0.45–0.85 in the hazards of experiencing a medication gap of 7 and 14 days or more, respectively. Conclusions: Patients’ adherence was improved with low-cost and easily implemented interventions using existing health facilities

    Best practices for integrating human immunodeficiency virus (HIV) testing and antiretroviral interventions for prevention and treatment are suggested based on research evidence and existing normative guidance. The goal is to provide high-impact prevention services during periods of substantial risk. Antiretroviral medications are recommended for postexposure prophylaxis (PEP), pre-exposure prophylaxis (PrEP), and treatment of HIV infection. We reviewed research evidence and current normative guidelines to identify best practices for integrating these high-impact prevention strategies. More sensitive HIV tests used for screening enable earlier diagnosis and treatment of HIV infection, more appropriate counseling, and help limit drug resistance. A fully suppressive PEP regimen should be initiated based on exposure history or physical findings when sensitive diagnostic testing is delayed or not available and antibody tests are negative. Transitions from PEP to PrEP are often warranted because HIV exposure events may continue to occur. This algorithmic approach to integrating PEP, PrEP, and early treatment decisions may increase the uptake of these interventions by a greater number and diversity of knowledgeable healthcare providers.

    There is a need to understand how social and cultural expectations of being a woman shape the challenges women face when trying to access antiretroviral therapy (ART) and to continue the treatment over time. Based on a 7-month prospective study of 15 HIV-infected women, the particular challenges...... met by these women in northern Vietnam are discussed in this article. We argued that, by taking ART to maintain their health and to fulfill their responsibilities to family and community, the women managed to reclaim the "moral worth" they had lost as a result of having HIV infection.

Nowadays, antiretroviral treatment (ART is available in health institutions and HIV-positive individuals who are eligible for ART are taking it. But studies show reinfection of HIV is occurring in them for unknown reasons. Purpose: This study aimed to assess risky sexual practice and associated factors among HIV-positive ART attendees. Methods: An institution-based cross-sectional study was employed in ten randomly selected health centers in Addis Ababa, between October 05 and November 05, 2013. Simple random sampling technique was employed to select 376 respondents for face-to-face interviews from ART registration book. After the data collection process, data were entered and analyzed using the SPSS version 20 statistical package. Then the effect of each variable was observed by regression analysis to identify the predictors for risky sexual practice at a significant level of P<0.05. Results: A total of 376 respondents were included in the study, with 100% response rate. The mean age of the total respondents was 35.28±8.94 (standard deviation. Of the 376 respondents, 30.4% had a history of risky sexual practice, which was inconsistent condom use in the last 3 months prior to the study period. Factors associated with risky sexual practice included alcohol consumption (adjusted odds ratio [AOR] =2.01, 95% CI: 1.07, 3.77, being single (AOR =0.29, 95% CI: 0.15, 0.59 and widowed (AOR =0.32, 95% CI: 0.13, 0.77 respondents, and the gender of the respondents, with an AOR of 1.55 (95% CI: 1.01, 2.33, shows a significant relationship with risky sexual behavior.

    Star celebrities such as Rock Hudson, Freddie Mercury, Magic Johnson, and Isaac Asimov have unfortunately something in common: they were all victims of the HIV global pandemic. Since then HIV infection has become considered a pandemic disease, and it is regarded as a priority in healthcare worldwide. It is ranked as the first cause of death among young people in industrialized countries, and it is recognized as a public healthcare problem due to its human, social, mass media, and economic impact. Incorporation of new and highly active antiretroviral treatment, available since 1996 for HIV/AIDS treatment, has provoked a radical change in the disease pattern, as well as in the impact on patient survival and quality of life. The pharmaceutical industry's contribution, based on the research for more active new drugs, has been pivotal. Mortality rates have decreased significantly in 20 years by 50% and now AIDS is considered a chronic and controlled disease. In this review we have studied the impact of HAART treatment on infected patients, allowing them to maintain their status as active workers and the decreased absenteeism from work derived from this, contributing ultimately to overall social wealth and, thus, to economic growth. Furthermore, an analysis of the impact on healthcare costs, quality of life per year, life per year gained, cost economic savings and cost opportunity among other parameters has shown that society and governments are gaining major benefits from the inclusion of antiretroviral therapies in HIV/AIDS patients.

    Full Text Available South Africa's national antiretroviral (ARV treatment program expanded in 2010 to include the nucleoside reverse transcriptase (RT inhibitors (NRTI tenofovir (TDF for adults and abacavir (ABC for children. We investigated the associated changes in genotypic drug resistance patterns in patients with first-line ARV treatment failure since the introduction of these drugs, and protease inhibitor (PI resistance patterns in patients who received ritonavir-boosted lopinavir (LPV/r-containing therapy.We analysed ARV treatment histories and HIV-1 RT and protease mutations in plasma samples submitted to the Tygerberg Academic Hospital National Health Service Laboratory.Between 2006 and 2012, 1,667 plasma samples from 1,416 ARV-treated patients, including 588 children and infants, were submitted for genotypic resistance testing. Compared with 720 recipients of a d4T or AZT-containing first-line regimen, the 153 recipients of a TDF-containing first-line regimen were more likely to have the RT mutations K65R (46% vs 4.0%; p<0.001, Y115F (10% vs. 0.6%; p<0.001, L74VI (8.5% vs. 1.8%; p<0.001, and K70EGQ (7.8% vs. 0.4% and recipients of an ABC-containing first-line regimen were more likely to have K65R (17% vs 4.0%; p<0.001, Y115F (30% vs 0.6%; p<0.001, and L74VI (56% vs 1.8%; p<0.001. Among the 490 LPV/r recipients, 55 (11% had ≥1 LPV-resistance mutations including 45 (9.6% with intermediate or high-level LPV resistance. Low (20 patients and intermediate (3 patients darunavir (DRV cross resistance was present in 23 (4.6% patients.Among patients experiencing virological failure on a first-line regimen containing two NRTI plus one NNRTI, the use of TDF in adults and ABC in children was associated with an increase in four major non- thymidine analogue mutations. In a minority of patients, LPV/r-use was associated with intermediate or high-level LPV resistance with predominantly low-level DRV cross-resistance.

    Full Text Available Background: Data on adverse drug reactions (ADRs related to antiretroviral (ARV use in public health practice are few indicating the need for antiretroviral therapy (ART safety surveillance in clinical care. Methods: 143 patients on ART were studied prospectively over a period of two years. All patients were asked to visit the clinic if they developed any symptoms or on a monthly basis. They were screened clinically and investigated suitably for any ADRs. Results: 143 HIV positive patients were analyzed. At least one ADR was seen in 87 (60.83% subjects. The most common ADR observed was peripheral neuropathy in 54 (37.76% patients, followed by lipodystrophy (13.98%, anemia (10.48% and hyperlipidemia (6.29%. Patients with peripheral neuropathy and lipodystrophy were mainly on stavudine based regimes, while patient with anemia and hyperlipidemia were on zidovudine based regimes. Conclusions: In spite of high ADRs, highly active antiretroviral therapy (HAART is the only answer to HIV/AIDS. To optimize adherence and thus, efficacy of ART, clinicians must focus on preventing adverse effects whenever possible, and distinguish those that are self-limited from those that are potentially serious.

  14. Electron beam processing programme: Wastewater and sludge treatment in Brazil

    International Nuclear Information System (INIS)

    The Institute for Energetic and Nuclear Research, working on environmental applications, has an extensive research programme using high energy electron beam in treating industrial wastewater and sludge. The experiments are being conducted in a pilot plant using an industrial electron beam 1.5MeV, 25mA, where the streams are presented to the scanned electron beam in counter flow. This pilot plant is designed to process approximately 3.0m3/h with an average dose 5kGy and the absorbed dose measurement is performed continuously by calorimetric system in real time. Combined biological and radiation treatment of domestic sewage and sludge were carried out to investigate disinfestation and removal of organic matter. The experiments showed that total and fecal coliforms were decreased by about 5 logs cycles with a 3.0kGy radiation dose in raw sewage and biological effluents, respectively. Concerning the industrial wastewater in the first stage of the programme, the irradiation was conducted using batch systems with samples originating from a Governmental Wastewater Treatment Plant. The data showed a significant color reduction effect when delivered dose was increased, and the opposite was noted for turbidity and total suspended solids. Other experiments were focused to process real industrial effluents from one of the most important chemical and pharmaceutical industries in Brazil. A special transport truck was used to transfer the liquid waste from the Industry to the Electron Beam Pilot Plant. Large quantities of liquid waste were irradiated with and without air addition with the doses from 2kGy to 20kGy. Such experiences performed in association with the Industry demonstrated that this technology has a great potential to be transferred and to contribute with a permanent cleanup alternative for hazardous wastes

    The association between substance abuse and intimate partner violence is quite robust. A promising area to improve treatment for the dual problems of substance abuse and violence perpetration is the identification of client characteristics and organisational and programme factors as predictors of health outcomes. Therefore, we examined associations of client, organisational and programme factors with outcomes in community health settings. Directors of 241 substance use disorder programmes (SUDPs) and 235 batterer intervention programmes (BIPs) reported outcomes of programme completion and substance use and violence perpetration rates at discharge; data collection and processing were completed in 2012. SUDPs having more female, non-white, younger, uneducated, unemployed and lower income clients reported lower completion rates. In SUDPs, private, for-profit programmes reported higher completion rates than public or private, non-profit programmes. SUDPs with lower proportions of their budgets from government sources, and higher proportions from client fees, reported better outcomes. Larger SUDPs had poorer programme completion and higher substance use rates. Completion rates in SUDPs were higher when clients could obtain substance- and violence-related help at one location, and programmes integrated violence-prevention contracting into care. In BIPs, few client, organisational and programme factors were associated with outcomes, but the significant factors associated with programme completion were consistent with those for SUDPs. Publicly owned and larger programmes, and SUDPs lacking staff to integrate violence-related treatment, may be at risk of poorer client outcomes, but could learn from programmes that perform well to yield better outcomes.

    Background. Decentralization of antiretroviral therapy (ART) services is a key strategy to achieving universal access to treatment for people living with HIV/AIDS. Our objective was to assess clinical and laboratory outcomes within a decentralized program in Nigeria. Methods. Using a tiered hub-and-spoke model to decentralize services, a tertiary hospital scaled down services to 13 secondary-level hospitals using national and program guidelines. We obtained sociodemographic, clinical, and immunovirologic data on previously antiretroviral drug naïve patients aged ≥15 years that received HAART for at least 6 months and compared treatment outcomes between the prime and satellite sites. Results. Out of 7,747 patients, 3729 (48.1%) were enrolled at the satellites while on HAART, prime site patients achieved better immune reconstitution based on CD4+ cell counts at 12 (P < 0.001) and 24 weeks (P < 0.001) with similar responses at 48 weeks (P = 0.11) and higher rates of viral suppression (<400 c/mL) at 12 (P < 0.001) and 48 weeks (P = 0.03), but similar responses at 24 weeks (P = 0.21). Mortality was 2.3% versus 5.0% (P < 0.001) at prime and satellite sites, while transfer rate was 8.7% versus 5.5% (P = 0.001) at prime and satellites. Conclusion. ART decentralization is feasible in resource-limited settings, but efforts have to be intensified to maintain good quality of care.

    Full Text Available Abstract Background For antiretroviral therapy (ART naive human immunodeficiency virus (HIV infected adults suffering from tuberculosis (TB, there is uncertainty about the optimal time to initiate highly active antiretroviral therapy (HAART after starting antituberculosis treatment (ATT, in order to minimize mortality, HIV disease progression, and adverse events. Methods In a randomized, open label trial at All India Institute of Medical Sciences, New Delhi, India, eligible HIV positive individuals with a diagnosis of TB were randomly assigned to receive HAART after 2-4 or 8-12 weeks of starting ATT, and were followed for 12 months after HAART initiation. Participants received directly observed therapy short course (DOTS for TB, and an antiretroviral regimen comprising stavudine or zidovudine, lamivudine, and efavirenz. Primary end points were death from any cause, and progression of HIV disease marked by failure of ART. Findings A total of 150 patients with HIV and TB were initiated on HAART: 88 received it after 2-4 weeks (early ART and 62 after 8-12 weeks (delayed ART of starting ATT. There was no significant difference in mortality between the groups after the introduction of HAART. However, incidence of ART failure was 31% in delayed versus 16% in early ART arm (p = 0.045. Kaplan Meier disease progression free survival at 12 months was 79% for early versus 64% for the delayed ART arm (p = 0.05. Rates of adverse events were similar. Interpretation Early initiation of HAART for patients with HIV and TB significantly decreases incidence of HIV disease progression and has good tolerability. Trial registration CTRI/2011/12/002260

    In October 2010, it will be exactly 25 years ago that the first antiretroviral drug, AZT (zidovudine, 3'-azido-2',3'-dideoxythymidine), was described. It was the first of 25 antiretroviral drugs that in the past 25 years have been formally licensed for clinical use. These antiretroviral drugs fall into seven categories [nucleoside reverse transcriptase inhibitors (NRTIs), nucleotide reverse transcriptase inhibitors (NtRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), protease inhibitors (PIs), fusion inhibitors (FIs), co-receptor inhibitors (CRIs) and integrase inhibitors (INIs). The INIs (i.e. raltegravir) represent the most recent advance in the search for effective and selective anti-HIV agents. Combination of several anti-HIV drugs [often referred to as highly active antiretroviral therapy (HAART)] has drastically altered AIDS from an almost uniformly fatal disease to a chronic manageable one.

    Full Text Available BACKGROUND: Childhood tuberculosis (TB patients under India's Revised National TB Control Programme (RNTCP are managed using diagnostic algorithms and directly observed treatment with intermittent thrice-weekly short-course treatment regimens for 6-8 months. The assignment into pre-treatment weight bands leads to drug doses (milligram per kilogram that are lower than current World Health Organization (WHO guidelines for some patients. OBJECTIVES: The main aim of our study was to describe the baseline characteristics and treatment outcomes reported under RNTCP for registered childhood (age <15 years TB patients in Delhi. Additionally, we compared the reported programmatic treatment completion rates between children treated as per WHO recommended anti-TB drug doses with those children treated with anti-TB drug doses below that recommended in WHO guidelines. METHODS: For this cross-sectional retrospective study, we reviewed programme records of all 1089 TB patients aged <15 years registered for TB treatment from January to June, 2008 in 6 randomly selected districts of Delhi. WHO disease classification and treatment outcome definitions are used by RNTCP, and these were extracted as reported in programme records. RESULTS AND CONCLUSIONS: Among 1074 patients with records available, 651 (61% were females, 122 (11% were <5 years of age, 1000 (93% were new cases, and 680 (63% had extra-pulmonary TB (EP-TB--most commonly peripheral lymph node disease [310 (46%]. Among 394 pulmonary TB (PTB cases, 165 (42% were sputum smear-positive. The overall reported treatment completion rate was 95%. Similar reported treatment completion rates were found in all subgroups assessed, including those patients whose drug dosages were lower than that currently recommended by WHO. Further studies are needed to assess the reasons for the low proportion of under-5 years of age TB case notifications, address challenges in reaching all childhood TB patients by RNTCP, the

    The aim of this study was to evaluate possible changes in predisposing factors in sexual preventive behaviors that could result from the availability of an efficient new antiretroviral therapy. A total of 136 young adults were randomly assigned a vignette to read describing AIDS as a lethal or chronic disease. After reading the vignette, the participants completed a self-administered questionnaire assessing the psychosocial determinants of intention to use a condom with a new sexual partner. The variables were measured according to Ajzen's (1985, 1988, 1991) theory of planned behavior and Triandis's (1977) theory of interpersonal behavior. The experimental manipulation was more successful when the disease was described as lethal (66 of the 68 subjects) rather than chronic (30 of the 68 subjects). For the 96 participants who correctly identified the expected outcome of the disease presented in the vignette, a significant difference in intention was found between the two experimental situations (p intention to use condoms on the psychosocial variables yielded an adjusted R2 of .62. Perceived behavioral control, social norms, personal normative belief and anticipated affective reaction were the significant variables explaining this intention. The results suggest that intention to use condoms with a new sexual partner is likely to be modified by the expected outcome of the disease, that is, whether lethal or chronic. Thus, it is suggested that interventions aimed at young adults take into account the impacts the new antiretroviral treatments are likely to have on preventive behaviors.

    2012-01-01

    Myelodysplastic syndromes (MDS) are often accompanied by autoimmune phenomena. The underlying mechanisms for these associations remain uncertain, although T cell activation seems to be important. Human T-lymphotropic virus (HTLV-1) has been detected in patients with myelodysplastic syndromes, mostly in regions of the world which are endemic for the virus, and where association of HTLV-1 with rheumatological manifestation is not rare. We present here the case of a 58 year old man who presented with cytopenias, leukocytoclastic vasculitis of the skin and glomerulopathy, and was diagnosed as MDS (refractory anemia with excess blasts - RAEB 1). The patient also tested positive for HTLV-1 by PCR. After 8 monthly cycles of 5-azacytidine he achieved a complete hematologic remission. Following treatment, a second PCR for HTLV-1 was carried out and found to be negative. This is the first report in the literature of a HTLV-1-positive MDS with severe autoimmune manifestations, which was treated with the hypomethylating factor 5-azacitidine, achieving cytogenetic remission with concomitant resolution of the autoimmune manifestations, as well as HTLV-1-PCR negativity. HTLV-1-PCR negativity may be due to either immune mediated clearance of the virus, or a potential antiretroviral effect of 5-azacytidine. 5-azacytidine is known for its antiretroviral effects, although there is no proof of its activity against HTLV-1 infection in vivo.

Most HIV clinics apply the patient self-report (PSR method. However, the reliability of this method in experienced HIV patients remains questionable.Purpose: To validate the PSR method for measuring adherence to ART using lamivudine (3TC plasma concentrations in experienced HIV patients.Methods: The study was conducted in Dar Es Salaam and involved 220 patients who were receiving ART services at HIV clinics for more than 12 months. Self-reported adherence information to ART was obtained on the day of HIV clinic visit. The patients were asked to mention the number of doses missed within the past 7 days. In addition, blood samples (2 mL were collected from each patient on the same day. The blood samples were determined for 3TC plasma concentrations. The target 3TC plasma concentration as indicator concentration for adherent patients was determined in 20 patients who took their evening dose of antiretrovirals under supervision. The blood from these patients was drawn 3 hours after drug administration.Results: Complete drug levels of 3TC and self-reported adherence data was obtained in 200 treatment-experienced HIV patients. Lamivudine plasma concentrations obtained in these patients ranged between 0.02–17.36 µg/mL.

    Full Text Available Abstract Background Universal access to antiretroviral therapy (ART in low- and middle-income countries faces numerous challenges: increasing numbers of people needing ART, new guidelines recommending more expensive antiretroviral (ARV medicines, limited financing, and few fixed-dose combination (FDC products. Global initiatives aim to promote efficient global ARV markets, yet little is known about market dynamics and the impact of global policy interventions. Methods We utilize several data sources, including 12,958 donor-funded, adult first-line ARV purchase transactions, to describe the market from 2002-2008. We examine relationships between market trends and: World Health Organization (WHO HIV/AIDS treatment guidelines; WHO Prequalification Programme (WHO Prequal and United States (US Food and Drug Administration (FDA approvals; and procurement policies of the Global Fund to Fight AIDS, Tuberculosis, and Malaria (GFATM, US President's Emergency Plan for AIDS Relief (PEPFAR and UNITAID. Results WHO recommended 7, 4, 24, and 6 first-line regimens in 2002, 2003, 2006 and 2009 guidelines, respectively. 2009 guidelines replaced a stavudine-based regimen ($88/person/year with more expensive zidovudine- ($154-260/person/year or tenofovir-based ($244-465/person/year regimens. Purchase volumes for ARVs newly-recommended in 2006 (emtricitabine, tenofovir increased >15-fold from 2006 to 2008. Twenty-four generic FDCs were quality-approved for older regimens but only four for newer regimens. Generic FDCs were available to GFATM recipients in 2004 but to PEPFAR recipients only after FDA approval in 2006. Price trends for single-component generic medicines mirrored generic FDC prices. Two large-scale purchasers, PEPFAR and UNITAID, together accounted for 53%, 84%, and 77% of market volume for abacavir, emtricitabine, and tenofovir, respectively, in 2008. PEPFAR and UNITAID purchases were often split across two manufacturers. Conclusions Global initiatives

    Full Text Available R Chris Rathbun, Michelle D LiedtkeDepartment of Clinical and Administrative Sciences, College of Pharmacy, University of Oklahoma Health Sciences Center, Oklahoma City, USAAbstract: Etravirine is a second-generation nonnucleoside reverse transcriptase inhibitor (NNRTI that is approved for the treatment of adult human immunodeficiency virus (HIV-infected patients with documented or suspected resistance to first-generation NNRTIs. Etravirine has a flexible molecular structure that allows it to retain its activity against mutant HIV strains that exhibit resistance to first-generation agents. It is evident that 3 or more etravirine resistance-associated mutations are typically necessary before clinical resistance to etravirine. Safety and efficacy of etravirine are established in antiretroviral treatment-experienced patients in combination with antiretroviral regimens that contain darunavir/ritonavir. In phase III studies, cutaneous reactions occurred in 19% of treated patients and are the most commonly observed adverse event. The typical manifestation is the development of a maculopapular rash within the first few weeks of etravirine therapy. Resolution commonly occurs within 1–2 weeks on continued therapy. Rare cases of severe skin reactions (<0.1% have been reported. Etravirine is hepatically metabolized by cytochrome P450 (CYP 3A4, CYP2C9, and CYP2C19. Drug interactions with some antiretrovirals (eg, unboosted protease inhibitors and fosamprenavir/ritonavir and medications for other comorbidities (eg, atorvastatin and clarithromycin have been reported and may require dosage adjustment for the coadministered drug or selection of alternative therapy in some instances. Administration of etravirine with potent inducers of CYP450 is not recommended due to the potential for subtherapeutic etravirine concentrations.

    Offered proper support, injection drug users (IDUs) can achieve the same levels of adherence to and clinical benefit from antiretroviral treatment (ARV) as other patients with HIV. Nonetheless, in countries of Asia and the former Soviet Union where IDUs represent the largest share of HIV cases, IDUs have been disproportionately less likely to receive ARV. While analysis of adherence amongst IDUs has focused on individual patient ability to adhere to medical regimens, HIV treatment systems themselves are in need of examination. Structural impediments to provision of ARV for IDUs include competing, vertical systems of care; compulsory drug treatment and rehabilitation services that often offer neither ARV nor effective treatment for chemical dependence; lack of opiate substitution treatments demonstrated to increase adherence to ARV; and policies that explicitly or implicitly discourage ARV delivery to active IDUs. Labeling active drug users as socially untrustworthy or unproductive, health systems can create a series of paradoxes that ensure confirmation of these stereotypes. Needed reforms include professional education and public campaigns that emphasize IDU capacity for health protection and responsible choice; recognition that the chronic nature of injecting drug use and its links to HIV infection require development of ARV treatment delivery that includes active drug users; and integrated treatment that strengthens links between health providers and builds on, rather than seeks to bypass, IDU social networks and organizations.

The objectives of this study are: (1 to determine the impact of the implementation of a pharmaceutical care program on improvement of ART adherence and on the immunovirological response of the patients; and (2 to detect possible correlations between different adherence evaluation measurements. Methods: A 60-month long retrospective study was conducted. Adherence measures used were: therapeutic drug monitoring, a simplified medication adherence questionnaire, and antiretroviral dispensation records (DR. The number of interviews and interventions related to adherence made for each patient in yearly periods was related to the changes in the adherence variable (measured with DR in these same yearly periods. The dates when the laboratory tests were drawn were grouped according to proximity with the study assessment periods (February–May, 2005–2010. Results: A total of 528 patients were included in the study. A significant relationship was observed between the simplified medication adherence questionnaire and DR over the 60-month study period (P < 0.01.

    Full Text Available We evaluated the effect of combination anti-retroviral treatment (cART on the host control of EBV infection in moderately immunosuppressed HIV-1 patients. Twenty HIV-1 infected individuals were followed for five years with repeated measurements of EBV DNA load in peripheral blood lymphocytes in relation to HIV-RNA titers and CD4+ cell counts. Individuals with optimal response, i.e. durable non-detectable HIV-RNA, showed a decline of EBV load to the level of healthy controls. Individuals with non-optimal HIV-1 control did not restore their EBV control. Long-lasting suppression of HIV-replication after early initiation of cART is a prerequisite for re-establishing the immune control of EBV.

    Background WHO recommends initiating combination antiretroviral treatment (ART) at the minimal threshold of 350 CD4 cells/mm3. In sub-Saharan Africa, the time for a recently infected patient to reach this threshold is unclear. Method We estimated the probability of reaching different CD4 thresholds over time in the ANRS 1220 cohort of HIV-1 seroconverters in Côte d’Ivoire. CD4 slopes were estimated using a mixed linear model. Probabilities of crossing the 350 and 500 CD4 cells/mm3 thresholds were estimated by the Kaplan-Meier method. Results Between 1997 and 2009, 304 recent seroconverters have been enrolled in the Primo-CI cohort (62% men, median baseline age 29 years, median time since the estimated date of seroconversion 9 months). The probability of having a first CD4 count below 500/mm3 was 0.57, 0.72, 0.79 and 0.84 at study entry, 2, 4 and 6 years, respectively. For a first CD4 count below 350/mm3, these figures were 0.29, 0.40, 0.55 and 0.67. The time for 75% of patients to reach the threshold was 3.0 years for 500 CD4/mm3 and 7.0 years for 350 CD4/mm3. Conclusion Almost one third of recent seroconverters had a CD4 count below the current ART eligibility threshold at first contact, about 6% more crossed it each subsequent year, and 25% remained above this threshold after 7 years. If the threshold was raised to 500 cells/mm3, 57% of recent seroconverters would immediately be eligible, while 14% would remain above the threshold at 7 years. These results should help modelers and treatment providers anticipate the need in antiretroviral drugs. PMID:21412060

    Full Text Available Background. Decentralization of antiretroviral therapy (ART services is a key strategy to achieving universal access to treatment for people living with HIV/AIDS. Our objective was to assess clinical and laboratory outcomes within a decentralized program in Nigeria. Methods. Using a tiered hub-and-spoke model to decentralize services, a tertiary hospital scaled down services to 13 secondary-level hospitals using national and program guidelines. We obtained sociodemographic, clinical, and immunovirologic data on previously antiretroviral drug naïve patients aged ≥15 years that received HAART for at least 6 months and compared treatment outcomes between the prime and satellite sites. Results. Out of 7,747 patients, 3729 (48.1% were enrolled at the satellites while on HAART, prime site patients achieved better immune reconstitution based on CD4+ cell counts at 12 (P<0.001 and 24 weeks (P<0.001 with similar responses at 48 weeks (P=0.11 and higher rates of viral suppression (<400 c/mL at 12 (P<0.001 and 48 weeks (P=0.03, but similar responses at 24 weeks (P=0.21. Mortality was 2.3% versus 5.0% (P<0.001 at prime and satellite sites, while transfer rate was 8.7% versus 5.5% (P=0.001 at prime and satellites. Conclusion. ART decentralization is feasible in resource-limited settings, but efforts have to be intensified to maintain good quality of care.

    Full Text Available Background: Ninety percent of the world's 2.1 million HIV-infected children live in sub-Saharan Africa, and 2.5% of South African children live with HIV. As HIV care and treatment programmes are scaled-up, a rise in loss to follow-up (LTFU has been observed. Objective: The aim of the study was to determine the rate of LTFU in children receiving antiretroviral treatment (ART and to identify baseline characteristics associated with LTFU in the first year of treatment. We also explored the effect of patient characteristics at 12 months treatment on LTFU in the second year. Methods: The study is an analysis of prospectively collected routine data of HIV-infected children at the Harriet Shezi Children's Clinic (HSCC in Soweto, Johannesburg. Cox proportional hazards models were fitted to investigate associations between baseline characteristics and 12-month characteristics with LTFU in the first and second year on ART, respectively. Results: The cumulative probability of LTFU at 12 months was 7.3% (95% CI 7.1–8.8. In the first 12 months on ART, independent predictors of LTFU were age <1 year at initiation, recent year of ART start, mother as a primary caregiver, and being underweight (WAZ ≤ −2. Among children still on treatment at 1 year from ART initiation, characteristics that predicted LTFU within the second year were recent year of ART start, mother as a primary caregiver, being underweight (WAZ ≤ −2, and low CD4 cell percentage. Conclusions: There are similarities between the known predictors of death and the predictors of LTFU in the first and second years of ART. Knowing the vital status of children is important to determine LTFU. Although HIV-positive children cared for by their mothers appear to be at greater risk of becoming LTFU, further research is needed to explore the challenges faced by mothers and other caregivers and their impact on long-term HIV care. There is also a need to investigate the effects of differential access to

    Treatment of malaria in HIV-infected individuals receiving antiretroviral therapy (ART) poses significant challenges. Artemether-lumefantrine (AL) is one of the artemisisnin-based combination therapies recommended for treatment of malaria. The drug combination is highly efficacious against sensitive and multidrug resistant falciparum malaria. Both artemether and lumefantrine are metabolized by hepatic cytochrome P450 (CYP450) enzymes which metabolize the protease inhibitors (PIs) and nonnucle...

    In recent years, a small but growing body of literature on the associations between common mental disorders and adherence to antiretroviral therapy (ART) has emerged. The present study builds on the growing body of research by investigating associations between symptoms of depression, symptoms of anxiety and adherence to ART. We studied a convenience sample of 101 South African ART users to determine the severity of symptoms of depression and anxiety and their association with self-reported adherence to ART. Based on the standardised cut-off scores recorded using the Beck Depression Inventory - Second Edition (BDI II), 40.4% of participants demonstrated moderate to severe symptoms of depression. Moreover, results from the Beck Anxiety Inventory (BAI) indicated that 28.7% of the study participants demonstrated moderate to severe symptoms of anxiety. Biserial correlations and logistic regression analysis demonstrated a significant relationship between symptoms of depression and adherence. The results indicate that patients reporting non-perfect adherence were approximately three times more likely (OR=2.73; CI=1.09-6.82) to have moderate to severe symptoms of depression than those reporting perfect adherence. The present findings are in keeping with those of previous studies, suggesting that depression may act as a barrier to ART adherence.

    Full Text Available Background: With the expansion of HIV-2 epidemic beyond African countries, co-infection with HIV-1 becomes a global challenge. We have recently identified an HIV-1/2 dual infection with both viruses bearing multiclass drug resistance in an untreated patient [1]. We now present the patient's combined antiretroviral treatment (cART outcome after 6 months follow-up. Patient and Methods: Clinical samples were obtained upon informed consent from a 23-year-old man living in Guinea-Bissau until March 2011 when he moved to Switzerland. As previously reported [1], HIV-1/2 co-infection was confirmed by HIV-1 PCR (21.000 copies/ml and total HIV-1/2 viremia (4.351 nU/ml by product-enhanced reverse transcriptase (PERT assay. The patient denied previous HIV testing or exposure to antiretroviral drugs. Dual infection consisted of HIV-1 CRF02_AG bearing resistance mutations M184V/V90I and HIV-2 clade A, harboring K65R/D67N mutations as amplified from proviral-DNA. Baseline CD4 + T-cell count was 408 cell/mm3. We initiated cART in accordance to drug resistance mutations (see below. Treatment compliance was assessed with an electronic pillbox device and drug-plasma concentrations. Clinical and laboratory follow up were done at weeks 2, 4, 9, 12 and 24. Results: cART was initiated with tenofovir/emtricitabine (TDF/FTC, boosted-darunavir (DRV/r and raltegravir(RAL. Treatment compliance was fluctuant during the first 3 months after which it remained stable with an average monthly intake of 92%. Antiretroviral drug-plasma concentrations were traced at percentile 25th. HIV-1 viremia became undetectable at week 12. Additionally, HIV-2 viremia was retrospectively assessed by real-time RT-PCR at two independent laboratories showing undetectable values across the study period including baseline. Thus, baseline viremia, as assessed by the PERT test for particle-associated reverse transcriptase activity was due to HIV-1 alone. CD4 + T-cell count was 559 cell/mm3 at

With international funding decreasing, determining the total cost of HIV/AIDS treatment is necessary in order to develop a master plan for the transition of ART services delivery and management. We analyzed the costs of HIV/AIDS treatment paid by both HIV programs and patients in a central outpatient clinic, and we explored factors associated with the capacity of patients to pay for this service. Methods: Patients (n=315 receiving ART in the Department of Infectious Diseases at Bach Mai Hospital, Hanoi, Vietnam, were interviewed. Patient records and expenses were reviewed. Results: The total cost of ART per patient was US$611 (75% from health care providers, 25% from patients or their families. The cost of a second-line regimen was found to be 2.7 times higher than the first-line regimen cost. Most outpatients (73.3% were able to completely pay for all of their ART expenses. Capacity to pay for ART was influenced by five factors, including marital status, distance from house to clinic, patient's monthly income, household economic condition, and health insurance status. Most of the patients (84.8% would have been willing to pay for health insurance if a copayment scheme for ART were to be introduced. Conclusion: This study provides evidence on payment capacity of HIV/AIDS patients in Vietnam and supplies information on ART costs from both provider and patient perspectives. In particular, results from this study suggest that earlier access to ART

    The burden of paediatric HIV in South Africa is extremely high. Antiretrovirals (ARVs) are now widely accessible in the country and the clinical emphasis has shifted from initiation of treatment to retention in care. This study describes the cumulative virological failure rate amongst children on ARVs in a peri-urban clinic, and suggests ways in which clinics and partners could improve treatment outcomes. The study was conducted by the non-profit organisation HOPE Cape Town Association. A retrospective file audit determined the cumulative virological failure rate, that is, the sum of all children with a viral load >1000 copies/ml, children on monotherapy, children who had stopped treatment, children lost to follow-up (LTFU) and children who had died. Interviews were conducted with a purposive sample of 12 staff members and a random sample of 21 caregivers and 4 children attending care. Cumulative virological failure rate was 42%, with most of those children having been LTFU. Both staff and caregivers consistently identified pharmacy queues, ongoing stigma and unpalatable ARVs as barriers to adherence. Staff suggestions included use of adherence aids, and better education and support groups for caregivers. Caregivers also requested support groups, as well as "same day" appointments for caregivers and children, but rejected the idea of home visits. Simple, acceptable and cost-effective strategies exist whereby clinics and their partners could significantly reduce the cumulative virological failure rate in paediatric ARV clinics. These include actively tracing defaulters, improving education, providing support groups, and campaigning for palatable ARV formulations.

    Introduction Tenofovir-based first-line antiretroviral therapy (ART) is recommended globally. To evaluate the impact of its incorporation into the World Health Organization (WHO) guidelines, we examined treatment failure and drug resistance among a cohort of patients on tenofovir-based first-line ART at the Academic Model Providing Access to Healthcare, a large HIV treatment programme in western Kenya. Methods We determined viral load (VL), drug resistance and their correlates in patients on ≥six months of tenofovir-based first-line ART. Based on enrolled patients’ characteristics, we described these measures in those with (prior ART group) and without (tenofovir-only group) prior non-tenofovir-based first-line ART using Wilcoxon rank sum and Fisher's exact tests. Results Among 333 participants (55% female; median age 41 years; median CD4 336 cells/µL), detectable (>40 copies/mL) VL was found in 18%, and VL>1000 copies/mL (WHO threshold) in 10%. Virologic failure at both thresholds was significantly higher in 217 participants in the tenofovir-only group compared with 116 in the prior ART group using both cut-offs (24% vs. 7% with VL>40 copies/mL; 15% vs. 1% with VL>1000 copies/mL). Failure in the tenofovir-only group was associated with lower CD4 values and advanced WHO stage. In 35 available genotypes from 51 participants in the tenofovir-only group with VL>40 copies/mL (69% subtype A), any resistance was found in 89% and dual-class resistance in 83%. Tenofovir signature mutation K65R occurred in 71% (17/24) of the patients infected with subtype A. Patients with K65R had significantly lower CD4 values, higher WHO stage and more resistance mutations. Conclusions In this Kenyan cohort, tenofovir-based first-line ART resulted in good (90%) virologic suppression including high suppression (99%) after switch from non-tenofovir-based ART. Lower virologic suppression (85%) and high observed resistance levels (89%) in the tenofovir-only group impact future treatment

  4. HIV treatment as prevention: optimising the impact of expanded HIV treatment programmes.

    Directory of Open Access Journals (Sweden)

    Wim Delva

    Full Text Available Until now, decisions about how to allocate ART have largely been based on maximising the therapeutic benefit of ART for patients. Since the results of the HPTN 052 study showed efficacy of antiretroviral therapy (ART in preventing HIV transmission, there has been increased interest in the benefits of ART not only as treatment, but also in prevention. Resources for expanding ART in the short term may be limited, so the question is how to generate the most prevention benefit from realistic potential increases in the availability of ART. Although not a formal systematic review, here we review different ways in which access to ART could be expanded by prioritising access to particular groups based on clinical or behavioural factors. For each group we consider (i the clinical and epidemiological benefits, (ii the potential feasibility, acceptability, and equity, and (iii the affordability and cost-effectiveness of prioritising ART access for that group. In re-evaluating the allocation of ART in light of the new data about ART preventing transmission, the goal should be to create policies that maximise epidemiological and clinical benefit while still being feasible, affordable, acceptable, and equitable.

    A retrospective cohort analysis comparing the efficacy of boosted protease inhibitor-based and efavirenz-based combination antiretroviral therapy in treatment-naïve people living with HIV with baseline resistance found that efavirenz-based treatment led to a shorter mean time to undetectable viral load. A higher proportion of patients with nonnucleoside reverse transcriptase inhibitor related baseline resistance mutations in the efavirenz-treatment group achieved an undetectable viral load at both 6 and 12 months post-treatment initiation, compared with the boosted protease-inhibitor-treatment group.Supplementary content: http://links.lww.com/QAD/A930.

    Full Text Available OBJECTIVES: Initiation of antiretroviral therapy (ART during pregnancy is critical to promote maternal health and prevent mother-to-child HIV transmission (PMTCT. The separation of services for antenatal care (ANC and ART may hinder antenatal ART initiation. We evaluated ART initiation during pregnancy under different service delivery models in Cape Town, South Africa. METHODS: A retrospective cohort study was conducted using routinely collected clinic data. Three models for ART initiation in pregnancy were evaluated ART 'integrated' into ANC, ART located 'proximal' to ANC, and ART located some distance away from ANC ('distal'. Kaplan-Meier methods and Poisson regression were used to examine the association between service delivery model and antenatal ART initiation. RESULTS: Among 14 617 women seeking antenatal care in the three services, 30% were HIV-infected and 17% were eligible for ART based on CD4 cell count <200 cells/µL. A higher proportion of women started ART antenatally in the integrated model compared to the proximal or distal models (55% vs 38% vs 45%, respectively, global p = 0.003. After adjusting for age and gestation at first ANC visit, women who at the integrated service were significantly more likely to initiate ART antenatally (rate ratio 1.33; 95% confidence interval: 1.09-1.64 compared to women attending the distal model; there was no difference between the proximal and distal models in antenatal ART initiation however (p = 0.704. CONCLUSIONS: Integration of ART initiation into ANC is associated with higher levels of ART initiation in pregnancy. This and other forms of service integration may represent a valuable intervention to enhance PMTCT and maternal health.

    Background Similar to other resource-limited settings, cost restricts availability of viral load monitoring for most patients receiving antiretroviral therapy in Tijuana, Mexico. We evaluated if a pooling method could improve efficiency and reduce costs while maintaining accuracy. Methods We evaluated 700 patient blood plasma specimens at a reference laboratory in Tijuana for detectable viremia, individually and in 10 × 10 matrix pools. Thresholds for virologic failure were set at ≥500, ≥1000 and ≥1500 HIV RNA copies per milliliter. Detectable pools were deconvoluted using pre-set algorithms. Accuracy and efficiency of the pooling method were compared with individual testing. Quality assurance (QA) measures were evaluated after 1 matrix demonstrated low efficiency relative to individual testing. Results Twenty-two percent of the cohort had detectable HIV RNA (≥50 copies/mL). Pooling methods saved approximately one third of viral load assays over individual testing, while maintaining negative predictive values of >90% to detect samples with virologic failure (≥50 copies/mL). One matrix with low relative efficiency would have been detected earlier using the developed QA measures, but its exclusion would have only increased relative efficiency from 39% to 42%. These methods would have saved between $13,223 and $14,308 for monitoring this cohort. Conclusions Despite limited clinical data, high prevalence of detectable viral loads and a contaminated matrix, pooling greatly improved efficiency of virologic monitoring while maintaining accuracy. By improving cost-effectiveness, these methods could provide sustainability of virologic monitoring in resource-limited settings, and incorporation of developed QA measures will most likely maximize pooling efficiency in future uses.

    Full Text Available Abstract Background Central nervous system (CNS exposure to HIV is a universal facet of systemic infection. Because of its proximity to and shared barriers with the brain, cerebrospinal fluid (CSF provides a useful window into and model of human CNS HIV infection. Methods Prospective study of the relationships of CSF to plasma HIV RNA, and the effects of: 1 progression of systemic infection, 2 CSF white blood cell (WBC count, 3 antiretroviral therapy (ART, and 4 neurological performance. One hundred HIV-infected subjects were cross-sectionally studied, and 28 were followed longitudinally after initiating or changing ART. Results In cross-sectional analysis, HIV RNA levels were lower in CSF than plasma (median difference 1.30 log10 copies/mL. CSF HIV viral loads (VLs correlated strongly with plasma VLs and CSF WBC counts. Higher CSF WBC counts associated with smaller differences between plasma and CSF HIV VL. CSF VL did not correlate with blood CD4 count, but CD4 counts In subjects starting ART, those with lower CD4 counts had slower initial viral decay in CSF than in plasma. In all subjects, including five with persistent plasma viremia and four with new-onset ADC, CSF HIV eventually approached or reached the limit of viral detection and CSF pleocytosis resolved. Conclusion CSF HIV infection is common across the spectrum of infection and is directly related to CSF pleocytosis, though whether the latter is a response to or a contributing cause of CSF infection remains uncertain. Slowing in the rate of CSF response to ART compared to plasma as CD4 counts decline indicates a changing character of CSF infection with systemic immunological progression. Longer-term responses indicate that CSF infection generally responds well to ART, even in the face of systemic virological failure due to drug resistance. We present simple models to explain the differing relationships of CSF to plasma HIV in these settings.

    OBJECTIVES: HIV-infected persons experience different patterns of viral suppression after initiating combination antiretroviral therapy (cART). The relationship between such differences and risk of virological failure after starting a new antiretroviral could help with patient monitoring strategies....... METHODS: A total of 1827 patients on cART starting at least one new antiretroviral from 1 January 2000 while maintaining a suppressed viral load were included in the analysis. Poisson regression analysis identified factors predictive of virological failure after baseline in addition to traditional...... demographic variables. Baseline was defined as the date of starting new antiretrovirals. RESULTS: Four hundred and fifty-one patients (24.7%) experienced virological failure, with an incidence rate (IR) of 7.3 per 100 person-years of follow-up (PYFU) [95% confidence interval (CI) 6.7-8.0].

    Full Text Available Introduction: We assessed the rate of treatment failure of HIV-infected children after 12 months on antiretroviral treatment (ART in the Paediatric IeDEA West African Collaboration according to their perinatal exposure to antiretroviral drugs for preventing mother-to-child transmission (PMTCT. Methods: A retrospective cohort study in children younger than five years at ART initiation between 2004 and 2009 was nested within the pWADA cohort, in Bamako-Mali and Abidjan-Côte d’Ivoire. Data on PMTCT exposure were collected through a direct review of children's medical records. The 12-month Kaplan-Meier survival without treatment failure (clinical or immunological was estimated and their baseline factors studied using a Cox model analysis. Clinical failure was defined as the appearance or reappearance of WHO clinical stage 3 or 4 events or any death occurring within the first 12 months of ART. Immunological failure was defined according to the 2006 World Health Organization age-related immunological thresholds for severe immunodeficiency. Results: Among the 1035 eligible children, PMTCT exposure was only documented for 353 children (34.1% and remained unknown for 682 (65.9%. Among children with a documented PMTCT exposure, 73 (20.7% were PMTCT exposed, of whom 61.0% were initiated on a protease inhibitor-based regimen, and 280 (79.3% were PMTCT unexposed. At 12 months on ART, the survival without treatment failure was 40.6% in the PMTCT-exposed group, 25.2% in the unexposed group and 18.5% in the children with unknown exposure status (p=0.002. In univariate analysis, treatment failure was significantly higher in children unexposed (HR 1.4; 95% CI: 1.0–1.9 and with unknown PMTCT exposure (HR 1.5; 95% CI: 1.2–2.1 rather than children PMTCT-exposed (p=0.01.

    The scale-up of antiretroviral therapy (ART) in Malawi was based on a public health approach adapted to its resource-poor setting, with principles and practices borrowed from the successful tuberculosis control framework. From 2004 to 2015, the number of new patients started on ART increased from about 3000 to over 820,000. Despite being a small country, Malawi has made a significant contribution to the 15 million people globally on ART and has also contributed policy and service delivery innovations that have supported international guidelines and scale up in other countries. The first set of global guidelines for scaling up ART released by the World Health Organization (WHO) in 2002 focused on providing clinical guidance. In Malawi, the ART guidelines adopted from the outset a more operational and programmatic approach with recommendations on health systems and services that were needed to deliver HIV treatment to affected populations. Seven years after the start of national scale-up, Malawi launched a new strategy offering all HIV-infected pregnant women lifelong ART regardless of the CD4-cell count, named Option B+. This strategy was subsequently incorporated into a WHO programmatic guide in 2012 and WHO ART guidelines in 2013, and has since then been adopted by the majority of countries worldwide. In conclusion, the Malawi experience of ART scale-up has become a blueprint for a public health response to HIV and has informed international efforts to end the AIDS epidemic by 2030. PMID:27600800

    Antiretroviral therapy (ART) is a lifelong treatment. To date, ART adherence is suboptimal for most patients in resource-poor settings. Previous research indicates that medication side effects are perceived to be a significant barrier of high ART adherence. Data regarding the role of adherence self-efficacy in mediating the relationship between side effects from ART and adherence to ART are limited; thus, this study examines this potential mediational role of self-efficacy. A cross-sectional survey of 2987 people living with HIV aged ≥18 years was conducted in 2012-2013 in Guangxi Autonomous Region (Guangxi) which has one of the fastest-growing HIV rates in China. Of the total sample, 2146 (72.1%) participants had initiated ART. Participants reported the number of days of completing the daily dose of ART in the past month; adherence was defined as completing the daily dose at least 28 days in the last month (≥90%). Side effects were significantly negatively related to adherence to ART. Mediation analyses indicated that adherence self-efficacy significantly mediated the side effects-adherence relationship. Future interventions to increase adherence self-efficacy and effective coping with side effects among HIV patients are needed in order to improve their ART adherence.

    In order to evaluate the effectiveness of a cognitive behavioural group therapy programme for the treatment of obesity in clinical practice, 122 patients from 14 general practices (n = 70) were randomised into either a treatment or a control arm with a ratio of 3 to 2. The group treatment programme was also assessed in a clinical centre (n = 52; University Hospital Basel). Before therapy, a clinical interview and a mental disorder examination were carried out on all patients. The instructors of the programme (practitioners; clinic physicians) were trained during two afternoon meetings to supervise the group sessions. The treatment programme consisted of 16 group sessions of 90 min each, and contained psycho-educational elements concerning a balanced diet, instruction for the integration of more activity in everyday life (lifestyle activity), problemsolving strategies, and the cognitive restructuring of dysfunctional cognition regarding the own body. All the patients who were treated in the various settings demonstrated a benefit from therapy. Compared to the control groups which received usual medical care, they were able to reduce their starting weight by around 5% (p attractiveness regarding their body and shape (p <0.05). These results support the effectiveness of the integrated cognitive behavioural treatment programme in clinical practice over a duration of 12 months. PMID:12707842

    The most recent UNAIDS figures indicate that approximately 30 million people are infected with HIV worldwide, 5.8 million of whom were newly infected during 1997. At the 10th International Conference on AIDS and Sexually Transmitted Diseases in Africa, the President and Secretary of Health of France called upon developed countries to establish a Therapeutic Assistance Fund to make antiretrovirals available to people with HIV/AIDS in sub-Saharan Africa. While the annual per capita health budget in most African countries is less than US$10, triple antiretroviral therapy against AIDS in the developed world costs $12,000-14,000 per patient per year. Calculations based upon a lower per patient cost of $7000, and treating all 1.4 million African AIDS cases, would cost US$10 billion per year for drugs alone, more than 30 times the amount currently spent annually by international donors for AIDS programs in the entire developing world. Basic infrastructural requirements would have to be met were antiretrovirals made widely available, ranging from HIV screening and counseling to the provision of clean water with which to consume the required 20-30 tablets per day. High program costs will challenge long-term sustainability. Universal access to care and treatment for HIV infection and AIDS is not a reality in the developed world, let alone feasible in developing countries. Given the competing health care priorities in developing countries, the high costs of antiretroviral agents, poor infrastructure, and inability to sustain such a program, the French initiative is ill-advised and foolish public health practice.

    Full Text Available Abstract Background The ocular manifestations of HIV may lead to visual impairment or blindness. In India, patients typically initiate antiretroviral treatment (ART with low CD4 cell counts when the risk of ocular complications may be high. The objective of this study was to determine the prevalence and types of HIV-associated ocular conditions in patients referred for ART in India. Methods This cross-sectional study was undertaken at a large public sector ART centre in Mumbai, India. Data collection including a standardised symptom screen, and an ophthalmic examination were performed on all consecutive patients satisfying the criteria for enrolment into the ART clinic irrespective of the presence or absence of ophthalmic/visual symptoms. Results Enrolled patients (n = 149 had a median CD4 cell count of 180 cell/μL (inter-quartile range [IQR], 106-253 cells/μL. The prevalence of HIV-associated ocular disease was 17.5% (95% CI, 11.2-23.6% in all participants and 23.8% (95% CI: 14.5-33.1 in those with CD4 cell counts Conclusion Over a fifth of unselected patients who are eligible for ART in this setting have HIV-related ocular disease of which CMVR is the most common form. Such patients may be at risk of developing ocular immune reconstitution phenomena during ART. Screening for ocular symptoms is not a reliable method to identify those with ocular morbidity and this highlights the need for routine ophthalmic screening prior to commencement of ART.

    Full Text Available Therapeutic HIV vaccines may prove helpful to intensify antiretroviral treatment (ART efficacy and may be an integral part of future cure strategies.We examined IFN-gamma ELISpot responses to a panel of 218 HIV clade B consensus-based HIV protease-reverse transcriptase peptides, designed to mimic previously described and predicted cytotoxic T lymphocyte epitopes overlapping drug resistance (DR positions, that either included the consensus sequence or the DR variant sequence, in 49 ART-naïve HIV-infected individuals. Next generation sequencing was used to assess the presence of minority DR variants in circulating viral populations.Although a wide spectrum of differential magnitudes of response to DR vs. WT peptide pairs was observed, responses to DR peptides were frequent and strong in the study cohort. No difference between the median magnitudes of response to DR vs. WT peptides was observed. Interestingly, of the 22 peptides that were recognized by >15% of the participants, two-thirds (64% corresponded to DR peptides. When analysing responses per peptide pair per individual, responses to only WT (median 4 pairs/individual or DR (median 6 pairs/individual were more common than responses to both WT and DR (median 2 pairs/individual; p<0.001. While the presence of ELISpot responses to WT peptides was frequently associated with the presence of the corresponding peptide sequence in the patient's virus (mean 68% of cases, responses to DR peptides were generally not associated with the presence of DR mutations in the viral population, even at low frequencies (mean 1.4% of cases; p = 0.0002.Our data suggests that DR peptides are frequently immunogenic and raises the potential benefit of broadening the antigens included in a therapeutic vaccine approach to immunogenic epitopes containing common DR sequences. Further studies are needed to assess the quality of responses elicited by DR peptides.

    The most common antiretroviral treatment (ART) received by individuals infected with HIV-1 in China is the combination therapy, comprised of nucleoside reverse transcriptase inhibitors (NRTIs) and nonnucleoside reverse transcriptase inhibitors (NNRTIs). To assess the prevalence of HIV-1 drug resistance and subtypes in Honghe of Yunnan, China, patient plasmas from ART-failed individuals were collected from January 2010 to December 2012. Genotyping was conducted using an in-house assay on patient plasmas. A total of 254 pol sequences were obtained. The prevalence of drug resistance was 47.2% in ART-failed individuals. Of these drug-resistant individuals, 51.7% harbored HIV strains dually resistant to NRTIs and NNRTIs or protease inhibitors (PIs) (34.2% for NNRTIs and 14.2% for NRTIs). Mutations such as M184V, A62V, T69Ins, K103N, Y181C, and G190A were common among the ART-failed individuals. The frequencies of M184V, A62V, and K103N were 20.5%, 11.0%, and 23.6%, respectively. The most common subtypes in Honghe were CRF08_BC (68.50%) and CRF07_BC (12.20%). The subtypes were almost consistent in different time points for one individual. When receiving ART for 6-12 months, the frequency of HIV-1 drug-resistant variants ranked first. This study shows that the high prevalence of HIV drug resistance observed among the ART-failed individuals should be of increasing concern (monitoring of resistance mutations) in ART regions and facilitate developing novel strategies for prevention and control of HIV infection in China.

    Full Text Available Foci of the HIV epidemic and helminthic infections largely overlap geographically. Treatment options for helminth infections are limited, and there is a paucity of drug-development research in this area. Limited evidence suggests that antiretroviral therapy (ART reduces prevalence of helminth infections in HIV-infected individuals. We investigated whether ART exposure and cotrimoxazole preventive therapy (CTX-P is associated with a reduced prevalence of helminth infections.This cross-sectional study was conducted at a primary HIV-clinic in Lambaréné, Gabon. HIV-infected adults who were ART-naïve or exposed to ART for at least 3 months submitted one blood sample and stool and urine samples on 3 consecutive days. Outcome was helminth infection with intestinal helminths, Schistosoma haematobium, Loa loa or Mansonella perstans. Multivariable logistic regression was used to assess associations between ART or CTX-P and helminth infection. In total, 408 patients were enrolled. Helminth infection was common (77/252 [30.5%]. Filarial infections were most prevalent (55/310 [17.7%], followed by infection with intestinal helminths (35/296 [11.8%] and S. haematobium (19/323 [5.9%]. Patients on CTX-P had a reduced risk of Loa loa microfilaremia (adjusted odds ratio (aOR 0.47, 95% CI 0.23-0.97, P = 0.04, also in the subgroup of patients on ART (aOR 0.36, 95% CI 0.13-0.96, P = 0.04. There was no effect of ART exposure on helminth infection prevalence.CTX-P use was associated with a decreased risk of Loa loa infection, suggesting an anthelminthic effect of antifolate drugs. No relation between ART use and helminth infections was established.

    Full Text Available BACKGROUND: Little is known about the variability of CD4 counts in the general population of sub-Saharan Africa countries affected by the HIV epidemic. We investigated factors associated with CD4 counts in a rural area in South Africa with high HIV prevalence and high antiretroviral treatment (ART coverage. METHODS: CD4 counts, health status, body mass index (BMI, demographic characteristics and HIV status were assessed in 4990 adult resident participants of a demographic surveillance in rural KwaZulu-Natal in South Africa; antiretroviral treatment duration was obtained from a linked clinical database. Multivariable regression analysis, overall and stratified by HIV status, was performed with CD4 count levels as outcome. RESULTS: Median CD4 counts were significantly higher in women than in men overall (714 vs. 630 cells/µl, p<0.0001, both in HIV-uninfected (833 vs. 683 cells/µl, p<0.0001 and HIV-infected adults (384.5 vs. 333 cells/µl, p<0.0001. In multivariable regression analysis, women had 19.4% (95% confidence interval (CI 16.1-22.9 higher CD4 counts than men, controlling for age, HIV status, urban/rural residence, household wealth, education, BMI, self-reported tuberculosis, high blood pressure, other chronic illnesses and sample processing delay. At ART initiation, HIV-infected adults had 21.7% (95% CI 14.6-28.2 lower CD4 counts than treatment-naive individuals; CD4 counts were estimated to increase by 9.2% (95% CI 6.2-12.4 per year of treatment. CONCLUSIONS: CD4 counts are primarily determined by sex in HIV-uninfected adults, and by sex, age and duration of antiretroviral treatment in HIV-infected adults. Lower CD4 counts at ART initiation in men could be a consequence of lower CD4 cell counts before HIV acquisition.

    Full Text Available BACKGROUND: Little is known about the long-term drug costs associated with treating AIDS in developing countries. Brazil's AIDS treatment program has been cited widely as the developing world's largest and most successful AIDS treatment program. The program guarantees free access to highly active antiretroviral therapy (HAART for all people living with HIV/AIDS in need of treatment. Brazil produces non-patented generic antiretroviral drugs (ARVs, procures many patented ARVs with negotiated price reductions, and recently issued a compulsory license to import one patented ARV. In this study, we investigate the drivers of recent ARV cost trends in Brazil through analysis of drug-specific prices and expenditures between 2001 and 2005. METHODS AND FINDINGS: We compared Brazil's ARV prices to those in other low- and middle-income countries. We analyzed trends in drug expenditures for HAART in Brazil from 2001 to 2005 on the basis of cost data disaggregated by each ARV purchased by the Brazilian program. We decomposed the overall changes in expenditures to compare the relative impacts of changes in drug prices and drug purchase quantities. We also estimated the excess costs attributable to the difference between prices for generics in Brazil and the lowest global prices for these drugs. Finally, we estimated the savings attributable to Brazil's reduced prices for patented drugs. Negotiated drug prices in Brazil are lowest for patented ARVs for which generic competition is emerging. In recent years, the prices for efavirenz and lopinavir-ritonavir (lopinavir/r have been lower in Brazil than in other middle-income countries. In contrast, the price of tenofovir is US$200 higher per patient per year than that reported in other middle-income countries. Despite precipitous price declines for four patented ARVs, total Brazilian drug expenditures doubled, to reach US$414 million in 2005. We find that the major driver of cost increases was increased purchase

    Full Text Available Background: Psychological disorders like depression and anxiety are potentially dangerous conditions. In the context of HIV/AIDS, this can influence health-seeking behavior or uptake of diagnosis and treatment for HIV/AIDS, add to the burden of disease for HIV patients, create difficulty in adherence to treatment, and increase the risk of mortality and morbidity. The objective of this study was to assess the prevalence and correlates of generalized psychological distress among HIV-infected subjects on antiretroviral treatment (ART. Design: An institution-based cross-sectional study was conducted. Interviews were conducted with 500 patients initiating ART at Dilla Referral Hospital. Generalized psychological distress was measured using the Hospital Anxiety and Depression Scale (HADS. A cutoff score ≥19 was used to identify possible cases of patients with generalized psychological distress. Multivariable logistic regression analysis using SPSS Version 20 was performed to identify factors associated with psychological distress. Results: The prevalence of generalized psychological distress among the population of this study was 11.2% (HADS≥19. Factors independently associated with generalized psychological distress were moderate stress (OR=6.87, 95% CI 2.27–20.81, low social support (OR=10.17, 95% CI 2.85–36.29, number of negative life events of six and above (OR=3.99, 95% CI 1.77–8.99, not disclosing HIV status (OR=5.24, 95% CI 1.33–20.62, and CD4 cell count of <200 cells/mm3 (OR=1.98, 95% CI 0.45–0.83 and 200–499 cells/mm3 (OR=3.53, 95% CI 1.62–7.73. Conclusions: This study provides prevalence of psychological distress lower than the prevalence of common mental disorders in Ethiopia and comparable to some other studies in sub-Saharan Africa. The findings are important in terms of their relevance to identifying high-risk groups for generalized psychological distress and preventing distress through integrating mental health

    Full Text Available Background & objectives: Mother-to-child transmission (MTCT is the most significant route of HIV transmission in children below the age of 15 yr. In India, perinatal HIV transmission, even after treatment, accounts for 5.4 per cent of HIV cases. The present study was conducted to evaluate the efficacy of anti-retro viral therapy (ART or prophylactic treatment (PT to control maternal viral load in HIV positive women, and its effect on vertical HIV transmission to their infants. Methods: A total of 58 HIV positive women were enrolled at the time of delivery and their plasma samples were obtained within 24 h of delivery for estimation of viral load. Viral load analysis was completed in 38 women. Infants received single dose nevirapine within 2 h of birth and zidovudine for 6 wk. At the end of 18 month follow up, HIV positive or negative status was available in 28 infants. Results: Results revealed undetectable levels of viral load in 58.3 per cent of women with ART compared to 30.7 per cent of women with PT. No women on ART had viral load more than 10,000 copies/ml, whereas seven (26.9%, P=0.07 women receiving PT had this viral load. Median CD4 count of women on PT (483 cells/μl was high compared to the women on ART (289 cells/ μl. At the end of 18 months follow up, only two children were HIV positive, whose mothers were on PT. One had in utero transmission; infection detected within 48 h of delivery, while the other child was infected post partum as HIV was detected at six months follow up. Interpretation & conclusions: Women who received a single dose of nevirapine during delivery had higher levels of viral load than women on ART. Combination drug therapy for pregnant women is now a standard of care in most of the western countries; use of nevirapine monotherapy at the time of delivery in our settings is not effective in controlling viral load. This highlights initiation of ART in pregnant women to control their viral load and thus to inhibit

    Full Text Available Background: In recent years, scaling up of antiretroviral therapy (ART in resource-limited settings moved impressively towards universal access. Along with these achievements, public health HIV programs are facing a number of challenges including the support of patients on lifelong therapy and the prevention of temporary/permanent loss of patients in care. Understanding reasons for treatment interruption (TI can inform strategies for improving drug adherence and retention in care. Objective: To evaluate key characteristics of patients resuming ART after TI at the Lighthouse Clinic in Lilongwe, Malawi, and to identify their reasons for interrupting ART. Design: This study uses a mixed methods design to evaluate patients resuming ART after TI. We analysed an assessment form for patients with TI using pre-defined categories and a comments field to identify frequently stated reasons for TI. Additionally, we conducted 26 in-depth interviews to deepen our understanding of common reasons for TI. In-depth interviews also included the patients’ knowledge about ART and presence of social support systems. Qualitative data analysis was based on a thematic framework approach. Results: A total of 347 patients (58.2% female, average age 35.1±11.3 years with TI were identified. Despite the presence of social support and sufficient knowledge of possible consequences of TI, all patients experienced situations that resulted in TI. Analysis of in-depth interviews led to new and distinct categories for TI. The most common reason for TI was travel (54.5%, n=80/147, which further differentiated into work- or family-related travel. Patients also stated transport costs and health-care-provider-related reasons, which included perceived/enacted discrimination by health care workers. Other drivers of TI were treatment fatigue/forgetfulness, the patients’ health status, adverse drug effects, pregnancy/delivery, religious belief or perceived/enacted stigma. Conclusions

    Full Text Available Abstract Background Indian manufacturers of generic antiretroviral (ARV medicines facilitated the rapid scale up of HIV/AIDS treatment in developing countries though provision of low-priced, quality-assured medicines. The legal framework in India that facilitated such production, however, is changing with implementation of the World Trade Organization Agreement on Trade-Related Aspects of Intellectual Property Rights, and intellectual property measures being discussed in regional and bilateral free trade agreement negotiations. Reliable quantitative estimates of the Indian role in generic global ARV supply are needed to understand potential impacts of such measures on HIV/AIDS treatment in developing countries. Methods We utilized transactional data containing 17,646 donor-funded purchases of ARV tablets made by 115 low- and middle-income countries from 2003 to 2008 to measure market share, purchase trends and prices of Indian-produced generic ARVs compared with those of non-Indian generic and brand ARVs. Results Indian generic manufacturers dominate the ARV market, accounting for more than 80% of annual purchase volumes. Among paediatric ARV and adult nucleoside and non-nucleoside reverse transcriptase inhibitor markets, Indian-produced generics accounted for 91% and 89% of 2008 global purchase volumes, respectively. From 2003 to 2008, the number of Indian generic manufactures supplying ARVs increased from four to 10 while the number of Indian-manufactured generic products increased from 14 to 53. Ninety-six of 100 countries purchased Indian generic ARVs in 2008, including high HIV-burden sub-Saharan African countries. Indian-produced generic ARVs used in first-line regimens were consistently and considerably less expensive than non-Indian generic and innovator ARVs. Key ARVs newly recommended by the World Health Organization are three to four times more expensive than older regimens. Conclusions Indian generic producers supply the majority of

    Full Text Available Abstract Background In South Africa the ever increasing demand for antiretroviral treatment (ART runs the risk of leading to sub-optimal care in public sector ART clinics that are overburdened and under resourced. This study assessed the quality of ART services to identify service areas that require improvement. Methods A cross-sectional study was carried out at 16 of 17 public ART clinics in the target area in greater Pretoria, South Africa. Trained participant observers presented as ART qualifying HIV positive patients that required a visit to assess treatment readiness. They evaluated each facility on five different occasions between June and November 2009, assessing the time it took to get an appointment, the services available and accessed, service quality and the duration of the visit. Services (reception area, clinician’s consultation, HIV counselling, pharmacy, nutrition counselling and social worker’s assessment were assessed against performance standards that apply to all clinics. Service quality was expressed as scores for clinic performance (CPS and service performance (SPS, defined as the percentage of performance standards met per clinic and service area. Results In most of the clinics (62.5% participant observers were able to obtain an appointment within one week, although on the day of their visit essential services could not always be accessed. The median CPS of the assessed facilities was 68.5 with four clinics not meeting minimum standards (CPS > 60. The service areas that performed least well were the clinician’s consultation (SPS 67.3 and HIV counselling (SPS 70.7. Most notably, clinicians performed a physical examination in only 41.1% of the visits and rarely did a complete TB symptom screening. Counsellors frequently failed to address prevention of HIV transmission. Conclusions Overall public sector ART clinics in greater Pretoria were easily accessible and their services were of an acceptable quality. However

    Positive Psychology, the study of "positive" factors or strengths and evidence-based interventions to increase them, is a rapidly developing field that is beginning to be applied to HIV care. Proactive coping and spirituality are two positive characteristics that have been examined in multiple chronic serious health conditions. In the present study, lost-to-care (LTCs; did not attend treatment for ≥12 months; n = 120) and engaged-in-care HIV clinic patients (EICs; attended treatment for ≥12 months and adherent with antiretrovirals; n = 120) in Leningrad Oblast, Russian Federation were compared on the Proactive Coping Inventory and View of God Scale. EICs had higher scores in proactive coping [t(229) = 3.69; p = .001] and instrumental [t(232) = 2.17; p = .03] and emotional [t(233) = 2.33; p = .02] support, indicating that they engage in autonomous goal setting and self-regulate their thoughts and behaviors; obtain advice and support from their social network; and cope with emotional distress by turning to others. LTCs had higher scores in avoidance coping [t(236) = -2.31; p = .02]. More EICs were spiritual, religious, or both [ χ(2)(1, N = 239) = 7.49, p = .006]. EICs were more likely to believe in God/Higher Power [χ(2)(1, N = 239 = 8.89, p = .002] and an afterlife [ χ(2)(1, N = 236) = 5.11, p = .024]; have a relationship with God/Higher Power [ χ(2)(1, N = 237) = 12.76, p = .000]; and call on God/Higher Power for help, healing, or protection [ χ(2)(1, N = 239) = 9.61]. EICs had more positive [t(238) = 2.78; p = .006] and less negative [t(236) = -2.38; p = .002] views of God. Similar proportions, but slightly more EICs than LTCs were members of a faith community; members of a12-step group; or attended religious or spiritual services, meetings, or activities. More EICs than LTCs engaged in private spiritual or religious activities, such as

    Full Text Available Introducción: En los estudios existentes sobre pacientes VIH+ la población a estudio ha sido tomada de manera homogénea, sin diferenciar aquella que cumple los requerimientos terapéuticos de la que no lo hace. Quizás por la dificultad en el acceso al grupo de pacientes que rehúsan el tratamiento antirretroviral. El medio penitenciario nos permite acceder a esta población, hasta hoy no estudiada. El objetivo de este estudio es describir el estado clínico y psicosocial de los reclusos seropositivos que rehúsan el TARV, comparándolo con el de aquellos que sí están en TARV o no se les indica tomarlo. Métodos: Estudio transversal con 585 reclusos VIH positivos ingresados en tres prisiones andaluzas entre mayo-julio de 2004. Como variable de agrupación se empleó rehusar el TARV, tomarlo o no hacerlo por no estar indicado. Como independientes se incluyeron sociodemográficas, psicosociales, clínicas y relacionadas con el medio penitenciario. Resultados: El 16,8% de los reclusos rehusaban el TARV, mientras el 56,3% estaban en tratamiento y al 26,8% no le estaba indicado. Entre los reclusos que rehusaban el TARV aparece una mayor prevalencia de coinfección por VHC, mayor consumo intrapenitenciario de opiáceos y tratamiento con metadona, más juicios pendientes y más entradas en prisión. Conclusiones: Estos resultados ponen de relieve la existencia de un grupo poblacional, accesible gracias al medio penitenciario, con características propias que no sigue las indicaciones terapéuticas y que representa un riesgo no sólo para su salud, sino para la de la comunidad.Introduction: Current studies of HIV+ patients in the prison population have been carried out without considering differences that might exist between patients who accept retroviral treatment and those who do not. One possible reason for this may be the difficulty in gaining access to patients who refuse antiretroviral treatment. However, the prison environment makes it

    Full Text Available BACKGROUND: Antiretroviral treatment (ART has been introduced in Ethiopia a decade ago and continues to be scaled up. However, there is dearth of literature on the impact of ART on changes in CD4 lymphocyte count and weight among patients on treatment. OBJECTIVE: To determine the predictors of change in CD4 lymphocyte count and weight among HIV/AIDS infected patients taking antiretroviral treatment in eastern Ethiopia. METHODS: A retrospective cohort study was conducted among HIV/AIDS patients taking ART from 2005 to 2010. A sample of 1540 HIV infected adult patients who started antiretroviral therapy in hospitals located in eastern Ethiopia were included in the study. The primary outcomes of interest were changes in CD4 count and weight. Descriptive statistics and multivariable regression analyses were performed to examine the outcomes among the cohort. RESULTS: Both the median CD4 lymphocyte counts and weight showed improvements in the follow up periods. The multivariate analysis shows that the duration of ART was an important predictor of improvements in CD4 lymphocyte count (beta 7.91; 95% CI 7.48-8.34; p 0.000 and weight (beta 0.15; 95% CI 0.13-0.18; p 0.000. Advanced WHO clinical stage, lower baseline CD4 cell count, and baseline hemoglobin levels were factors associated with decline in weight. Actively working patients had higher CD4 lymphocyte count and weight compared to those that were ambulatory (p<0.05. CONCLUSION: We detected a substantial increment in weight and CD4 lymphocyte count among the patients who were taking ART in eastern Ethiopia. Patients who are of older age, with low initial CD4 lymphocyte count, late stage of the WHO clinical stages and lower hemoglobin level may need special attention. The reasons for the improved findings on CD4 count and weight throughout the five years of follow up merit further investigation.

    Information on efficacy of long-term antiretroviral treatment (ART) exposure in resource-limited countries is still scarce. In 767 patients attending routine HIV centers in Togo and receiving first-line ART for more than four years, 42% had viral load greater than 1000 copies/ml and either were on a completely ineffective ART regime or were with only a single drug active. The actual conditions to ensure lifelong ART in resource-limited countries can have dramatic long-term outcomes.

    Introduction The scale-up of highly active antiretroviral therapy (HAART) has led to a significant improvement in survival of the HIV-positive patient but its effects on health-related quality of life (HRQOL) are less known and context-dependent. Our aim was to assess the temporal changes and factors associated with HRQOL among HIV-positive adults initiating HAART in Burkina Faso. Methods HIV-positive people initiating HAART were prospectively included and followed over a one-year period in three HIV clinics of Ouagadougou. HRQOL was assessed at baseline and at each follow-up visit using physical (PHS) and mental (MHS) summary scores derived from the Medical Outcome Study 36-Item short-form health survey (MOS SF-36) questionnaire. Toxicity related to HAART modification and self-reported symptoms were recorded during follow-up visits. Determinants associated with baseline and changes in both scores over a one-year period were assessed using a mixed linear model. Results A total of 344 patients were included. Their median age at baseline was 37 years [interquartile range (IQR) 30–44] and their median CD4 count was 181 cells/mm3 (IQR 97–269). The mean [standard deviation (SD)] PHS score increased from 45.4 (11.1) at baseline to 60.0 (3.1) at 12 months (p<10−4) and the mean (SD) MHS score from 42.2 (8.7) to 43.9 (3.4) (p<10−2). After one year of treatment, patients that experienced on average two symptoms during follow-up presented with significantly lower PHS (63.9) and MHS (43.8) scores compared to patients that presented no symptoms with PHS and MHS of 68.2 (p<10−4) and 45.3 (p<10−3), respectively. Discussion The use of HAART was associated with a significant increase in both physical and mental aspects of the HRQOL over a 12-month period in this urban African population. Perceived symptoms experienced during follow-up visits were associated with a significant impairment in HRQOL. The appropriate and timely management of reported symptoms during the

    Full Text Available AIM: Previous economic literature on the cost-effectiveness of antiretroviral treatment (ART programs has been mainly focused on the microeconomic consequences of alternative use of resources devoted to the fight against the HIV pandemic. We rather aim at forecasting the consequences of alternative scenarios for the macroeconomic performance of countries. METHODS: We used a micro-simulation model based on individuals aged 15-49 selected from nationally representative surveys (DHS for Cameroon, Tanzania and Swaziland to compare alternative scenarios : 1-freezing of ART programs to current levels of access, 2- universal access (scaling up to 100% coverage by 2015, with two variants defining ART eligibility according to previous or current WHO guidelines. We introduced an "artificial" ageing process by programming methods. Individuals could evolve through different health states: HIV negative, HIV positive (with different stages of the syndrome. Scenarios of ART procurement determine this dynamics. The macroeconomic impact is obtained using sample weights that take into account the resulting age-structure of the population in each scenario and modeling of the consequences on total growth of the economy. RESULTS: Increased levels of ART coverage result in decreasing HIV incidence and related mortality. Universal access to ART has a positive impact on workers' productivity; the evaluations performed for Swaziland and Cameroon show that universal access would imply net cost-savings at the scale of the society, when the full macroeconomic consequences are introduced in the calculations. In Tanzania, ART access programs imply a net cost for the economy, but 70% of costs are covered by GDP gains at the 2034 horizon, even in the extended coverage option promoted by WHO guidelines initiating ART at levels of 350 cc/mm(3 CD4 cell counts. CONCLUSION: Universal Access ART scaling-up strategies, which are more costly in the short term, remain the best economic

    Full Text Available PURPOSE: A lower daily pill burden may improve adherence to antiretroviral treatment (ART and clinical outcomes in patients with human immunodeficiency virus (HIV. This study assessed differences in adherence using the number of pills taken per day, and evaluated how adherence correlated with hospitalization. METHODOLOGY: Commercially insured patients in the LifeLink database with an HIV diagnosis (International Classification of Diseases, 9th Revision, Clinical Modification code 042.xx between 6/1/2006 and 12/31/2008 and receipt of a complete ART regimen were selected for inclusion. Patients were grouped according to their daily pill count and remained on ART for at least 60 days. Outcomes included adherence and rates of hospitalization. Adherence was measured as the proportion of days between the start and end of the regimen in which the patient maintained supply of all initiated ART components. Logistic regressions assessed the relationship between pills per day, adherence, and hospitalization, controlling for demographics, comorbidities, and ART-naïve (vs. experienced status. RESULTS: 7,073 patients met the study inclusion criteria, and 33.4%, 5.8%, and 60.8% received an ART regimen comprising one, two, or three or more pills per day, respectively. Regression analysis showed patients receiving a single pill per day were significantly more likely to reach a 95% adherence threshold versus patients receiving three or more pills per day (odds ratio [OR] = 1.59; P<0.001. Regardless of the number of pills received per day, patients were over 40% less likely to have a hospitalization if they were adherent to therapy (OR = 0.57; P<0.001. Patients receiving a single pill per day were 24% less likely to have a hospitalization versus patients receiving three or more pills per day (OR = 0.76; P = 0.003. CONCLUSIONS: ART consisting of a single pill per day was associated with significantly better adherence and lower risk of hospitalization in patients

    Full Text Available Introduction: Antiretroviral resistance leads to treatment failure and resistance transmission. Resistance data in western Kenya are limited. Collection of non-plasma analytes may provide additional resistance information. Methods: We assessed HIV diversity using the REGA tool, transmitted resistance by the WHO mutation list and acquired resistance upon first-line failure by the IAS–USA mutation list, at the Academic Model Providing Access to Healthcare (AMPATH, a major treatment programme in western Kenya. Plasma and four non-plasma analytes, dried blood-spots (DBS, dried plasma-spots (DPS, ViveSTTM-plasma (STP and ViveST-blood (STB, were compared to identify diversity and evaluate sequence concordance. Results: Among 122 patients, 62 were treatment-naïve and 60 treatment-experienced; 61% were female, median age 35 years, median CD4 182 cells/µL, median viral-load 4.6 log10 copies/mL. One hundred and ninety-six sequences were available for 107/122 (88% patients, 58/62 (94% treatment-naïve and 49/60 (82% treated; 100/122 (82% plasma, 37/78 (47% attempted DBS, 16/45 (36% attempted DPS, 14/44 (32% attempted STP from fresh plasma and 23/34 (68% from frozen plasma, and 5/42 (12% attempted STB. Plasma and DBS genotyping success increased at higher VL and shorter shipment-to-genotyping time. Main subtypes were A (62%, D (15% and C (6%. Transmitted resistance was found in 1.8% of plasma sequences, and 7% combining analytes. Plasma resistance mutations were identified in 91% of treated patients, 76% NRTI, 91% NNRTI; 76% dual-class; 60% with intermediate-high predicted resistance to future treatment options; with novel mutation co-occurrence patterns. Nearly 88% of plasma mutations were identified in DBS, 89% in DPS and 94% in STP. Of 23 discordant mutations, 92% in plasma and 60% in non-plasma analytes were mixtures. Mean whole-sequence discordance from frozen plasma reference was 1.1% for plasma-DBS, 1.2% plasma-DPS, 2.0% plasma-STP and 2

    Full Text Available Scabies is a major public health problem in the Pacific and is associated with an increased risk of bacterial skin infections, glomerulonephritis and rheumatic fever. Mass drug administration with ivermectin is a promising strategy for the control of scabies. Mass treatment with ivermectin followed by active case finding was conducted in five communities in the Solomon Islands between 1997 and 2000 and resulted in a significant reduction in the prevalence of both scabies and bacterial skin infections.We conducted a prospective follow-up study of the communities where the original scabies control programme had been undertaken. All residents underwent a standardised examination for the detection of scabies and impetigo.Three hundred and thirty eight residents were examined, representing 69% of the total population of the five communities. Only 1 case of scabies was found, in an adult who had recently returned from the mainland. The prevalence of active impetigo was 8.8% overall and 12.4% in children aged 12 years or less.We found an extremely low prevalence of scabies 15 years after the cessation of a scabies control programme. The prevalence of impetigo had also declined further since the end of the control programme. Our results suggest that a combination of mass treatment with ivermectin and intensive active case finding may result in long term control of scabies. Larger scale studies and integration with other neglected tropical disease control programmes should be priorities for scabies control efforts.

    Background Identification of risk for non-adherence to treatment is a challenge for personalized care for people living with HIV. Standardized questionnaires of patients’ expectations of their capability to overcome obstacles for treatment adherence may be used as a pre-screening for risk identification. A scale of self-efficacy expectations of adherence to antiretroviral treatment (SEA-ART scale) was previously developed. This study assesses the scale validity in predicting non-adherence to ART in adults living with HIV. Methods and Findings A prospective cohort study applied a 21-item SEA-ART scale to 275 adults in ART treatment at an outpatient public service for HIV in Southern Brazil. ART medications taken were assessed at one-month follow-up; ART adherence was devised as an intake of 95% and more of the prescribed medication. A SEA-ART score was calculated by adding up the scores of all items. Multivariable logistic regression and the Area Under the Receiver-Operating-Characteristic Curve (AUROC) were applied to examine the ability of the SEA-ART score to predict non-adherence at follow-up. The SEA-ART score varied from 21 to 105; mean 93.9; median 103.0. Non-adherence was 30.3% (n = 81/267). The odds of non-adherence was 8% lower for each unit increase of the SEA-ART score; after adjustment for age, sex, formal education and time in treatment (OR = 0.92; 95%CI 0.90–0.95; LRT for linear trend, p = 0.002). The AUROC was 0.80 (95%CI 0.73–0.87; p<0.001). The SEA-ART optimal cut-off value was 101, providing a sensitivity of 76.5%, a specificity of 73.1%, a positive predictive value of 55.4% and a negative predictive value of 87.7%. There was no evidence of difference in sensitivity, and specificity among groups organized by age, gender, formal education and time in treatment. Conclusions The SEA-ART scale appears to have a good capacity to discriminate between adherents and non-adherents at one-month follow-up. Further studies should confirm these results

    Full Text Available Abstract Background Efforts to increase access to life-saving treatment, including antiretroviral therapy (ART, for people living with HIV/AIDS in resource-limited settings has been the growing focus of international efforts. One of the greatest challenges to scaling up will be the limited supply of adequately trained human resources for health, including doctors, nurses, pharmacists and other skilled providers. As national treatment programmes are planned, better estimates of human resource needs and improved approaches to assessing the impact of different staffing models are critically needed. However there have been few systematic assessments of staffing patterns in existing programmes or of the estimates being used in planning larger programmes. Methods We reviewed the published literature and selected plans and scaling-up proposals, interviewed experts and collected data on staffing patterns at existing treatment sites through a structured survey and site visits. Results We found a wide range of staffing patterns and patient-provider ratios in existing and planned treatment programmes. Many factors influenced health workforce needs, including task assignments, delivery models, other staff responsibilities and programme size. Overall, the number of health care workers required to provide ART to 1000 patients included 1–2 physicians, 2–7 nurses, Discussion These data are consistent with other estimates of human resource requirements for antiretroviral therapy, but highlight the considerable variability of current staffing models and the importance of a broad range of factors in determining personnel needs. Few outcome or cost data are currently available to assess the effectiveness and efficiency of different staffing models, and it will be important to develop improved methods for gathering this information as treatment programmes are scaled up.

    The treatment programme for sex offenders at the Prince of Wales Hospital, Sydney, is described. Penile circumference assessment is not used as there is no evidence it provides a valid measure of individuals' paedophile or rapist tendencies. Sex offenders' self-reports remain the major source of information in their assessment. The development of the two major techniques used--imaginal desensitization and short-term medroxyprogesterone--is outlined. About 80% of subjects can be expected to show a good response to one or other of these therapies. Of those who do not, most respond to the alternative or aversive therapy. Adolescent offenders appear to require more intensive treatment. Results appear comparable with those of more intensive programmes in use overseas. PMID:2204335

    Objective:To determine socio-cultural, demographic and highly active antiretroviral therapy (HAART) program-related factors associated with immunological failure (IF) among clients on HAART in Dar es Salaam care and treatment clinics. Methods:A 1:2 matched case control study was done from February to April 2012 in HIV/AIDS care and treatment clinics in Dar es Salaam. Data were collected from National AIDS Control Program (NACP) data base and patient’s charts to obtain 60 sets of study participants who were interviewed using the structured questionnaire. Data analysis was done by using EPI Info 3.5.1 version. Results:The mean age of all study participants was (42.00±9.07) years with 35% (63) being males. History of poor antiretroviral therapy (ART) adherence due to exposure to drug holiday with loss to follow up (OR=11.96;95%CI=2.07-69.26), history of changing care and treatment clinics (OR=12.07;95%CI=2.10-69.27) and the lack of treatment supporter (OR=23.26;95%CI=1.85-291.66) were found to be strongly associated with the occurrence of first line HAART-IF. Conclusions:HAART-IF in Dar es Salaam is associated with ART programmatic and patients’ centered challenges. There is a need to review the approaches on ensuring ART adherence, clients follow up and referral system so as to reduce the incidence of IF as we move to a more decentralized peripheral drug picks clinical initiative.

    Full Text Available Background. Regular clinic attendance for antiretroviral (ARV drug refills is important for successful clinical outcomes in HIV management. Methods. Clinic attendance for ARV drug refills and medication adherence using a clinic-based pill count in 392 adult patients receiving antiretroviral therapy (ART in a district hospital in Uganda were prospectively monitored over a 28-week period. Results. Of the 2267 total scheduled clinic visits, 40 (1.8% were missed visits. Among the 392 clients, 361 (92% attended all appointments for their refills (regular attendance. Clinic attendance for refills was statistically significantly associated with medication adherence with regular attendant clients having about fourfold greater odds of achieving optimal (≥95% medication adherence [odds ratio (OR=3.89, 95% CI: 1.48 to 10.25, exact P=.013]. In multivariate analysis, clients in age category 35 years and below were less likely to achieve regular clinic attendance. Conclusion. Monitoring of clinic attendance may be an objective and effective measure and could be a useful adjunct to an adherence measure such as pill counting in resource-constrained settings. Where human resource constraints do not allow pill counts or other time-consuming measures, then monitoring clinic attendance and acting on missed appointments may be an effective proxy measure.

    Background Antiretroviral therapy (ART) restores immune function and reduces HIV-related adverse outcomes. But treatment failure erodes this advantage and leads to an increased morbidity and compromised quality of life in HIV patients. The aim of this study was to determine the prevalence and factors associated with first-line ART failure in HIV patients at the University of Gondar Teaching Hospital. Patients and methods A retrospective study was conducted on 340 adults who had started ART during the period of September 2011 to May 2015. Data regarding patients’ sociodemographics, baseline characteristics, and treatment-related information were collected through review of their medical charts. Data were analyzed using SPSS version 21. Descriptive statistics, cross-tabs, and binary and multiple logistic regressions were utilized. Page at ART initiation was 34.4 years. A total of 14 (4.1%) patients were found to have treatment failure. The median duration of treatment failure from initiation of treatment was 17.5 months (8–36 months). Poor adherence to treatment and low baseline CD4 cell count were found to be significant predictors of treatment failure. Conclusion The prevalence of first-line ART failure was 4.1%. Treatment failure was most likely to occur for the patients who had poor drug adherence and those who were delayed to start ART till their CD4 cell count became very low (<100 cells/mm3).

    Full Text Available The major antiretroviral guidelines recommend starting ART in patients>50 y of age, regardless of CD4 cell count. However, no references to the preferred cART for these patients have been described. The combination FTC/TDF is one of the cornerstones of combined antiretroviral therapy (cART in naïve patients. We studied the persistence of coformulated FTC/TDF in this scenario. National, retrospective cohort analysis of HIV-infected patients>50 y at the time they began the first cART regimen (January 1, 2006 – December 31, 2009. Patients were selected in a proportion 2:1 to FTC/TDF vs. other NRTI regimens (no-TDF. We compared the persistence of treatment in FTC/TDF users vs. no-TDF (main groups. Among TDF users, we compared the persistence in PI vs. NNRTI users and in lopinavir/r vs. efavirenz users. Persistence was defined as the duration of the initial treatment; we analyzed time to any change or discontinuation according to initial regimen. We included 161 patients: median age: 54.6 y, 83% males, median CD4 count 191 cells/μl, median viral load 4.7 log, follow up: median 19 months, max 48 months. Of them, 112 started with FTC/TDF (53 with PIs, 57 with NNRTIs; and 49 with other NRTIs (no-TDF (22 with PI, 23 NNRTI. During the follow-up period 79 patients (49% modified their treatment, with statistically significant differences among groups, as shown in Table 1.*Adjusted by age, sex, transmission category and baseline CD4 count and viral load. In our study (antiretroviral-naïve patients>50 y, the persistence of FTC/TDF regimens was significantly higher than other NRTI regimens. According to the third agent, there was a trend to a higher persistence with NNRTI vs. PI. This reaches statistical significance when we compare EFV vs. LPV/r. In the absence of randomized clinical trials, our data may contribute to a better understanding on how cART works in this ageing population, which is progressively increasing.

    Full Text Available The purpose of this study was to analyze characteristics, reasons for transferring, and reasons for discontinuing care among patients defined as lost to follow-up (LTFU from an antiretroviral therapy (ART clinic in Nairobi, Kenya.The study used a prospective cohort of patients who participated in a randomized, controlled ART adherence trial between 2006 and 2008.Participants were followed from pre-ART clinic enrollment to 18 months after ART initiation, and were defined as LTFU if they failed to return to clinic 4 weeks after their last scheduled visit. Reasons for loss were captured through phone call or home visit. Characteristics of LTFU who transferred care and LTFU who did not transfer were compared to those who remained in clinic using log-binomial regression to estimate risk ratios.Of 393 enrolled participants, total attrition was 83 (21%, of whom 75 (90% were successfully traced. Thirty-seven (49% were alive at tracing and 22 (59% of these reported having transferred their antiretroviral care. In the final model, transfers were more likely to have salaried employment [Risk Ratio (RR, 2.7; 95% confidence interval (CI, 1.2-6.1; p=0.020] and pay a higher monthly rent (RR, 5.8; 95% CI, 1.3-25.0; p=0.018 compared to those retained in clinic. LTFU who did not transfer care were three times as likely to be men (RR, 3.1; 95% CI, 1.1-8.1; p=0.028 and nearly 4 times as likely to have a primary education or less (RR, 3.8; 95% CI, 1.3-10.6; p=0.013. Overall, the most common reason for LTFU was moving residence, predominantly due to job loss or change in employment.A broad definition of LTFU may include those who have transferred their antiretroviral care and thereby overestimate negative effects on ART continuation. Interventions targeting men and considering mobility due to employment may improve retention in urban African ART clinics.The study's ClinicalTrials.gov identifier is NCT00273780.

    Full Text Available Abstract Background While the number of HIV-positive patients on antiretroviral therapy (ART in resource-limited settings has increased dramatically, some patients eligible for treatment do not initiate ART even when it is available to them. Understanding why patients opt out of care, or are unable to opt in, is important to achieving the goal of universal access. Methods We conducted a cross-sectional survey among 400 patients on ART (those who were able to access care and 400 patients accessing home-based care (HBC, but who had not initiated ART (either they were not able to, or chose not to, access care in two rural and two urban sites in Zambia to identify barriers to and facilitators of ART uptake. Results HBC patients were 50% more likely to report that it would be very difficult to get to the ART clinic than those on ART (RR: 1.48; 95% CI: 1.21-1.82. Stigma was common in all areas, with 54% of HBC patients, but only 15% of ART patients, being afraid to go to the clinic (RR: 3.61; 95% CI: 3.12-4.18. Cost barriers differed by location: urban HBC patients were three times more likely to report needing to pay to travel to the clinic than those on ART (RR: 2.84; 95% CI: 2.02-3.98 and 10 times more likely to believe they would need to pay a fee at the clinic (RR: 9.50; 95% CI: 2.24-40.3. In rural areas, HBC subjects were more likely to report needing to pay non-transport costs to attend the clinic than those on ART (RR: 4.52; 95% CI: 1.91-10.7. HBC patients were twice as likely as ART patients to report not having enough food to take ART being a concern (27% vs. 13%, RR: 2.03; 95% CI: 1.71-2.41, regardless of location and gender. Conclusions Patients in home-based care for HIV/AIDS who never initiated ART perceived greater financial and logistical barriers to seeking HIV care and had more negative perceptions about the benefits of the treatment. Future efforts to expand access to antiretroviral care should consider ways to reduce these barriers

    Antiretroviral therapy (ART) offers a powerful intervention in HIV but effectiveness can be compromised by inadequate adherence. This paper is a detailed examination of the experience of medication in a purposively selected group of people living with HIV. In-depth interviews were conducted with 10 HIV positive, West African women of black heritage living in London, UK. This group was of interest since it is the second largest group affected by HIV in the UK. Interviews were subjected to interpretative phenomenological analysis, an idiographic, experiential, qualitative approach. The paper details the women's negative experience of treatment. ART can be considered difficult and unrelenting and may be disconnected from the women's sense of health or illness. Participants' social context often exacerbated the difficulties. Some reported an improvement in their feelings about the medication over time. These findings point to some intrinsic and social motivators which could act as spurs to adherence.

    Individuals infected with the human immunodeficiency virus (HIV-1) present with decreased CD4, a progressive increase in viral load, compromised cell immune defense, and hematologic alterations. The aim of this study was to assess the serum viral load, CD4, CD8, lymphocyte count and hematocrit at the beginning of antiretroviral therapy in individuals who were supplemented with N-acetylcysteine (NAC). Twenty volunteers participated in this double-blind, placebo-controlled 180-day study. Ten participants received 600 mg of NAC per day (NAC group) and the other ten serving as a control group received placebo. The above mentioned parameters were determined before treatment, and after 60, 120 and 180 days. In NAC-treated patients hematocrit remained stable and an increase in CD4 cell count took place earlier than that in the control group.

    BACKGROUND: Studies from high-income settings show that both food insecurity and common mental disorders (CMDs) are associated with lower quality of life among people living with HIV (PLHIV). However, there is limited research among PLHIV in sub-Saharan Africa. In this study we tested...... the hypothesis that food insecurity and CMDs would be associated with poorer quality of life of PLHIV in Ethiopia. METHODS: A cross-sectional study was carried out with 348 PLHIV who were initiating antiretroviral therapy recruited from two primary care centers and a tertiary Hospital in southwest Ethiopia. Food...... insecurity, CMD, and quality of life were measured using instruments adapted and validated in Ethiopia (Household Food Insecurity Access Scale, Kessler-6, and WHOQOL-HIV-BREF-ETH, respectively). Multiple linear regression analysis was used to identify factors associated with quality of life after adjusting...

    Full Text Available BACKGROUND: Although the importance of concurrent treatment for multidrug-resistant tuberculosis (MDR-TB and HIV co-infection has been increasingly recognized, there have been few studies reporting outcomes of MDR-TB and HIV co-treatment. We report final outcomes of comprehensive, integrated MDR-TB and HIV treatment in Lesotho and examine factors associated with death or treatment failure. METHODS: We reviewed clinical charts of all adult patients who initiated MDR-TB treatment in Lesotho between January 2008 and September 2009. We calculated hazard ratios (HR and used multivariable Cox proportional hazards regression to identify predictors of poor outcomes. RESULTS: Of 134 confirmed MDR-TB patients, 83 (62% were cured or completed treatment, 46 (34% died, 3 (2% transferred, 1 (1% defaulted, and 1 (1% failed treatment. Treatment outcomes did not differ significantly by HIV status. Among the 94 (70% patients with HIV co-infection, 53% were already on antiretroviral therapy (ART before MDR-TB treatment initiation, and 43% started ART a median of 16 days after the start of the MDR-TB regimen. Among HIV co-infected patients who died, those who had not started ART before MDR-TB treatment had a shorter median time to death (80 days vs. 138 days, p=0.065. In multivariable analysis, predictors of increased hazard of failure or death were low and severely low body mass index (HR 2.75, 95% confidence interval [CI] 1.27-5.93; HR 5.50, 95% CI 2.38-12.69, and a history of working in South Africa (HR 2.37, 95% CI 1.24-4.52. CONCLUSIONS: Favorable outcomes can be achieved in co-infected patients using a community-based treatment model when both MDR-TB and HIV disease are treated concurrently and treatment is initiated promptly.

    Full Text Available Abstract Background Although highly active antiretroviral therapy (HAART has dramatically decreased HIV-related morbidity and mortality, the associated costs, toxicities, and resistance risks make the potential delay of HAART initiation an attractive goal. Suppression of herpes simplex virus type 2 (HSV-2 may be a novel strategy for achieving this goal because HSV-2 is associated with clinically significant increases in HIV viral load, the primary driver of HIV disease progression. Methods/Design The VALacyclovir In Delaying Antiretroviral Treatment Entry (VALIDATE trial is a multicentre, randomized, fully blinded, clinical trial of twice daily valacyclovir 500 mg versus placebo for delaying the need for initiating HAART among HIV-1, HSV-2 co-infected HAART-naïve adults. 480 participants from Canada, Brazil and Argentina will undergo quarterly clinical follow-up until reaching the composite primary endpoint of having a CD4+ T-cell count ≤ 350 cells/mm3 or initiation of HAART for any reason, whichever occurs first. The primary analysis will use a proportional hazards model, stratified by site, to estimate the relative risk of progression to this endpoint associated with valacyclovir. Secondary analyses will compare the rates of change in CD4 count, median log10 HIV viral load, drug-related adverse events, frequency of HSV reactivations, rate of acyclovir-resistant HSV, and quality of life between study arms. Discussion Although HIV treatment guidelines continue to evolve, with some authorities recommending earlier HAART among asymptomatic individuals, the potential delay of HAART remains a clinically relevant goal for many. If shown to be of benefit, implementation of the VALIDATE intervention will require careful consideration of both individual patient-level and public health implications.

    Full Text Available Combination antiretroviral therapy (cART reduces HIV-associated morbidities and mortalities but cannot cure the infection. Given the difficulty of eradicating HIV-1, a functional cure for HIV-infected patients appears to be a more reachable short-term goal. We identified 14 HIV patients (post-treatment controllers [PTCs] whose viremia remained controlled for several years after the interruption of prolonged cART initiated during the primary infection. Most PTCs lacked the protective HLA B alleles that are overrepresented in spontaneous HIV controllers (HICs; instead, they carried risk-associated HLA alleles that were largely absent among the HICs. Accordingly, the PTCs had poorer CD8+ T cell responses and more severe primary infections than the HICs did. Moreover, the incidence of viral control after the interruption of early antiretroviral therapy was higher among the PTCs than has been reported for spontaneous control. Off therapy, the PTCs were able to maintain and, in some cases, further reduce an extremely low viral reservoir. We found that long-lived HIV-infected CD4+ T cells contributed poorly to the total resting HIV reservoir in the PTCs because of a low rate of infection of naïve T cells and a skewed distribution of resting memory CD4+ T cell subsets. Our results show that early and prolonged cART may allow some individuals with a rather unfavorable background to achieve long-term infection control and may have important implications in the search for a functional HIV cure.

    Full Text Available This study assesses association between CD4 level at initiation of antiretroviral treatment (ART on subsequent treatment outcomes and mortality among people infected with HIV via various routes in Hunan province, China. Over a period of 10 years, a total of 7333 HIV-positive patients, including 553 (7.5% MSM, 5484 (74.8% heterosexuals, 1164 (15.9% injection drug users (IDU and 132 (1.8% former plasma donors (FPD, were recruited. MSM substantially demonstrated higher initial CD4 cell level (242, IQR 167–298 than other populations (Heterosexuals: 144 IQR 40–242, IDU: 134 IQR 38–224, FPD: 86 IQR 36–181. During subsequent long-term follow up, the median CD4 level in all participants increased significantly from 151 cells/mm3 (IQR 43–246 to 265 cells/mm3 (IQR 162–380, whereas CD4 level in MSM remained at a high level between 242 and 361 cells/mm3. Consistently, both cumulative immunological and virological failure rates (10.4% and 26.4% in 48 months, respectively were the lowest in MSM compared with other population groups. Survival analysis indicated that initial CD4 counts ≤200 cells/mm3 (AHR = 3.14; CI, 2.43–4.06 significantly contributed to HIV-related mortality during treatment. Timely diagnosis and treatment of HIV patients are vital for improving CD4 level and health outcomes.

    2011-01-01

    Full Text Available Treatment of malaria in HIV-infected individuals receiving antiretroviral therapy (ART poses significant challenges. Artemether-lumefantrine (AL is one of the artemisisnin-based combination therapies recommended for treatment of malaria. The drug combination is highly efficacious against sensitive and multidrug resistant falciparum malaria. Both artemether and lumefantrine are metabolized by hepatic cytochrome P450 (CYP450 enzymes which metabolize the protease inhibitors (PIs and nonnucleoside reverse transcriptase inhibitors (NNRTIs used for HIV treatment. Coadministration of NNRTIs and PIs with AL could potentially cause complex pharmacokinetic drug interactions. NNRTI by inducing CYP450 3A4 enzyme and PIs by inhibiting CYP450 3A4 enzymes could influence both artemether and lumefantrine concentrations and their active metabolites dihydroartemisinin and desbutyl-lumefantrine, predisposing patients to poor treatment response, toxicity, and risk for development of resistance. There are scanty data on these interactions and their consequences. Pharmacokinetic studies to evaluate these interactions in the target populations are urgently needed.

    Full Text Available SUMMARY Combination Antiretroviral Therapy (cART aims to inhibit viral replication, delay immunodeficiency progression and improve survival in AIDS patients. The objective of this study was to compare two different schemes of cART, based on plasma viral load (VL and CD4+ T lymphocyte count, during 48 weeks of treatment. For this purpose, 472 medical charts of a Specialized Outpatient Service were reviewed from 1998 to 2005. Out of these, 58 AIDS patients who had received a triple drug scheme as the initial treatment were included in the study and two groups were formed: Group 1 (G1: 47 individuals treated with two nucleoside reverse-transcriptase inhibitors (NRTI and one non-nucleoside reverse-transcriptase inhibitor; Group 2 (G2: 11 patients treated with two NRTI and one protease inhibitor. In G1 and G2, 53.2% and 81.8% respectively were patients with an AIDS-defining disease. The T CD4+ lymphocyte count increased progressively up until the 24th week of treatment in all patients, while VL became undetectable in 68.1% of G1 and in 63.6% of G2. The study concluded that the evolutions of laboratory tests were similar in the two treatment groups and that both presented a favorable clinical evolution.

    Full Text Available Introduction: Previously published UK data on HIV transmitted drug resistance (TDR shows that it ranges between 3 and 9.4% [1,2]. However, there are no recent data from populations where HIV transmission rates are increasing. The aim of this study was to assess the prevalence of TDR in untreated HIV-infected individuals attending three HIV specialist clinics under the HIV Directorate, Chelsea and Westminster Hospital and based throughout London – the Kobler Clinic, 56 Dean Street and West London Centre for Sexual Health. Methods: We included all patients with a HIV diagnosis, no history of antiretroviral therapy (ART intake, attending one of the three clinics (Kobler (K, 56 Dean Street (DS and West London (WL, between 2011 and 2013 who started antiretrovirals. Reverse transcriptase (RT and protease region sequencing was performed using Vircotype virtual phenotype resistance analysis. Drug resistance mutations were identified according to Stanford University HIV Drug Resistance Database (http://hivdb.stanford.edu/. Results: Among 1705 HIV-1-infected patients enrolled in the study, 1252 were males (919 were MSM, 107 were females and 346 had no gender recorded. Ethnicity was 51.1% white British/Irish/other, 6.1% African, 2.1% Caribbean, 2.8% Asian, 1.3% Indian/Pakistani/Bangladeshi, 4.2%, other, 3.2% not stated, and 29.2% unknown. 547 were from K (84.3% males, 48.3% MSM, 826 were from DS (84.3% males, 71.9% MSM, and 109 from WL (87.2% males, 56.0% MSM, 223 from other sites not specified. 77.5% (1321 of 1705 of patients had baseline viral resistance testing performed. Prevalence of primary resistance in those with a baseline viral resistance test was 13.5% overall: 19.3% in K, 14.9% in DS, and 14.7% in WL. The most common mutations detected were: NRTI: 184V, 215F, 41L; NNRTI 103N, 179D, 90I; PI 90M, 46I, and 82A.

    Full Text Available BACKGROUND: Survival analysis using time-updated CD4+ counts during antiretroviral therapy is frequently employed to determine risk of clinical events. The time-point when the CD4+ count is assumed to change potentially biases effect estimates but methods used to estimate this are infrequently reported. METHODS: This study examined the effect of three different estimation methods: assuming i a constant CD4+ count from date of measurement until the date of next measurement, ii a constant CD4+ count from the midpoint of the preceding interval until the midpoint of the subsequent interval and iii a linear interpolation between consecutive CD4+ measurements to provide additional midpoint measurements. Person-time, tuberculosis rates and hazard ratios by CD4+ stratum were compared using all available CD4+ counts (measurement frequency 1-3 months and 6 monthly measurements from a clinical cohort. Simulated data were used to compare the extent of bias introduced by these methods. RESULTS: The midpoint method gave the closest fit to person-time spent with low CD4+ counts and for hazard ratios for outcomes both in the clinical dataset and the simulated data. CONCLUSION: The midpoint method presents a simple option to reduce bias in time-updated CD4+ analysis, particularly at low CD4 cell counts and rapidly increasing counts after ART initiation.

    The update of these adult antiretroviral treatment (cART) recommendations has been carried out by consensus of a panel consisting of members of the Grupo de Estudio de Sida (Gesida, AIDS Study Group) and the Plan Nacional sobre el Sida (PNS, Spanish AIDS Plan) who have reviewed the antiretroviral efficacy and safety advances in clinical trials, cohort and pharmacokinetic studies published in medical journals (PubMed and Embase), or presented in medical scientific meetings. Three levels of evidence were defined according to the data source: randomized studies (level A), cohort or case-control studies (level B), and expert opinion (level C). The decision to recommend, consider or not to recommend antiretroviral treatment (ART) was established by consensus in each situation. The current treatment of choice for HIV infection is the combination of three drugs. Combined ART is recommended in patients with symptomatic HIV infection, and guidelines on this treatment in patients with an opportunistic type C infection are included. In asymptomatic patients, initiation of ART is recommended on the basis of CD4 lymphocyte counts, plasma viral load and patient co-morbidities, as follows: a) therapy should be started in patients with CD4 counts cells/μL; b) Therapy should be recommended when CD4 counts are between 350 and 500 cells/μL, except when CD4 are stabilized, there is low plasma viral load, or the patient not willing; c) Therapy could be deferred when CD4 counts are above 500 cells/ μL, but should be considered in cases of cirrhosis, chronic hepatitis C, hepatitis B fulfilling treatment criteria, high cardiovascular risk, HIV nephropathy, viral load > 100,000 copies/ mL, proportion of CD4 cells 55 years, and in cases of discordant serological sexual couples in order to reduce transmission. cART should include 2 reverse transcriptase inhibitor nucleoside analogues (AN) and a non-analogue reverse transcriptase inhibitor (NN) or 2 AN and a ritonavir boosted protease

    Full Text Available Abstract Background The emergence of resistance to first line antiretroviral therapy (ART regimen leads to the need for more expensive and less tolerable second line drugs. Hence, it is essential to identify and address factors associated with an increased probability of first line ART regimen failure. The objective of this article is to report on the predictors of first line ART regimen failure, the detection rate of ART regime failure, and the delay in switching to second line ART drugs. Methods A retrospective cohort study was conducted from 2005 to 2011. All HIV infected children under the age of 15 who took first line ART for at least six months at the four major hospitals of Addis Ababa, Ethiopia were included. Data were collected, entered and analyzed using Epi info/ENA version 3.5.1 and SPSS version 16. The Cox proportional-hazard model was used to assess the predictors of first line ART failure. Results Data of 1186 children were analyzed. Five hundred seventy seven (48.8% were males with a mean age of 6.22 (SD = 3.10 years. Of the 167(14.1% children who had treatment failure, 70 (5.9% had only clinical failure, 79 (6.7% had only immunologic failure, and 18 (1.5% had both clinical and immunologic failure. Patients who had height for age in the third percentile or less at initiation of ART were found to have higher probability of ART treatment failure [Adjusted Hazard Ratio (AHR, 3.25 95% CI, 1.00-10.58]. Patients who were less than three years old [AHR, 1.85 95% CI, 1.24-2.76], chronic diarrhea after initiation of antiretroviral treatment [AHR, 3.44 95% CI, 1.37-8.62], ART drug substitution [AHR, 1.70 95% CI, 1.05-2.73] and base line CD4 count below 50 cells/mm3 [AHR, 2.30 95% CI, 1.28-4.14] were also found to be at higher risk of treatment failure. Of all the 167 first line ART failure cases, only 24 (14.4% were switched to second line ART with a mean delay of 24 (SD = 11.67 months. The remaining 143 (85.6% cases were diagnosed

    This consensus document has been prepared by a panel consisting of members of the AIDS Study Group (Gesida) and the Spanish Secretariat for the National Plan on AIDS (SPNS) after reviewing the efficacy and safety results of clinical trials, cohort and pharmacokinetic studies published in medical journals, or presented in medical scientific meetings. Gesida has prepared an objective and structured method to prioritise combined antiretroviral treatment (cART) in naïve patients. Recommendations strength (A, B, C) and the evidence which supports them (I, II, III) are based on a modification of the Infectious Diseases Society of America criteria. The current antiretroviral treatment (ART) of choice for chronic HIV infection is the combination of three drugs. ART is recommended in patients with symptomatic HIV infection, in pregnancy, in serodiscordant couples with high transmission risk, hepatitis B fulfilling treatment criteria, and HIV nephropathy. Guidelines on ART treatment in patients with concurrent diagnosis of HIV infection and an opportunistic type C infection are included. In asymptomatic patients ART is recommended on the basis of CD4 lymphocyte counts, plasma viral load and patient co-morbidities, as follows: 1) therapy should be started in patients with CD4 counts cells/μL; 2) when CD4 counts are between 350 and 500 cells/μL, therapy will be recommended and only delayed if patient is reluctant to take it, the CD4 are stabilised, and the plasma viral load is low; 3) therapy could be deferred when CD4 counts are above 500 cells/μL, but should be considered in cases of cirrhosis, chronic hepatitis C, high cardiovascular risk, plasma viral load >10(5) copies/mL, proportion of CD4 cells 55 years. ART should include 2 reverse transcriptase inhibitors nucleoside analogues and a third drug (non-analogue reverse transcriptase inhibitor, ritonavir boosted protease inhibitor or integrase inhibitor).

    Full Text Available Abstract Background Zambia is facing a double crisis of increasing malaria burden and dwindling capacity to deal with the endemic malaria burden. The pursuit of sustainable but equity mechanisms for financing malaria programmes is a subject of crucial policy discussion. This requires that comprehensive accounting of the economic impact of the various malaria programmes. Information on the economic value of programmes is essential in soliciting appropriate funding allocations for malaria control. Aims and objectives This paper specifically seeks to elicit a measure of the economic benefits of an improved malaria treatment programme in Zambia. The paper also studies the equity implications in malaria treatment given that demand or malaria treatment is determined by household socio-economic status. Methods A contingent valuation survey of about 300 Zambian households was conducted in four districts. Willingness-to-pay (WTP was elicited for an improved treatment programme for malaria in order to generate a measure of the economic benefits of the programme. The payment card method was used in eliciting WTP bids. Findings The study reports that malaria treatment has significant economic benefits to society. The total economic benefits of an improved treatment programme were estimated at an equivalent of US$ 77 million per annum, representing about 1.8% of Zambia's GDP. The study also reports the theoretically anticipated association between WTP and several socio-economic factors. Our income elasticity of demand is positive and similar in magnitude to estimates reported in similar studies. Finally, from an equity standpoint, the constraints imposed by income and socio-economic status are discussed.

The score includes the following predictors: Prior ART exposure (1 point, CD4-count below baseline (1, 25% and 50% drop from peak CD4-count (1 and 2, hemoglobin drop≥1 g/dL (1, CD4 count40 copies (95%CI: 84-100, and of 90% to detect a VL ≥ 5000 copies (70-97. Within the score, adherence<95%, CD4-count<100/µl and papular pruritic eruption were the strongest single predictors. Among 47 patients failing, 8 (17% died before or within 4 weeks after being switched. Overall mortality was 4 (20% among those with score ≥ 5 and 4 (5% if score<5 (OR 4.3; 95%CI: 0.96-18.84, p = 0.057. CONCLUSION: A score ≥ 5 among patients fulfilling WHO-criteria had a PPV of 100% for a detectable VL and 90% for viral failure. In settings without regular access to VL-testing, this PPV may be considered high enough to switch this patient-group to second-line treatment without confirmatory VL-test.

    Strategies for use of antiretroviral therapy (ART) have traditionally focused on providing treatment to persons who stand to benefit immediately from initiating the therapy. There is global consensus that any HIV+ person with CD4 counts less than 350 cells/μl should initiate ART. However...... always been vigorously debated. The lack of an evidence base from randomized trials, in conjunction with varying degrees of therapeutic aggressiveness and optimism tempered by the risks of drug resistance and side effects, has resulted in divided expert opinion and inconsistencies among treatment...

    The introduction of potent anti-retroviral treatment (ART) has transformed HIV disease into a chronic condition with the prospect, for the patient, of strict adherence to effective but life-long treatments. Within this framework, a major issue that can negatively affect adherence is the side-effects of the treatment. To date, studies documenting how individuals HIV-infected through drug injection (IDUs) experience ART-related side effects are sparse. Longitudinal data collected from the APROCO-COPILOTE cohort have been used to compare the experience of ART-related side-effects who have been HIV-infected via injecting drug use and non-IDU patients. A 20-item list was used to collect self-reported side-effects over a 7-year follow up period. Of 922 patients, 15% were IDUs. At any given visit, IDUs reported a significantly higher number of side-effects and had approximately twice the risk of reporting any side effect than non-IDUs. Most commonly reported side-effects were dry skin, fatigue, vomiting, bone troubles, insomnia. After adjustment for social conditions, depressive symptoms, use of sleeping pills and time since HIV diagnosis, IDUs reported experiencing significantly more side-effects than non-IDUs. Whether or not this is related to sensitivity to pain or to other comorbidities is difficult to establish. Further research is needed to understand how substitution treatment can mediate the relationship between exposure to opioids and side-effects. Providing appropriate care to reduce side-effects, thereby increasing adherence to ART in this population, remains a major challenge especially in those countries scaling up ART. Incorporating symptom management and improving access to analgesic medications within a model of comprehensive care for HIV-infected IDUs, could reduce the impact of drug-related and HIV-related harms and induce better long-term treatment outcomes and quality of life.

    Full Text Available Abstract Objective To assess efficacy, adherence and tolerability of once daily antiretroviral therapy containing tenofovir disoproxil fumarate (DF 300 mg in HIV-1-infected former injecting drug users receiving opiate treatment (IVDU. Methods European, 48-week, open-label, single-arm, multicenter study. Patients were either antiretroviral therapy-naïve, restarting therapy after treatment discontinuation without prior virological failure or switching from existing stable treatment. Results Sixty-seven patients were enrolled in the study and 41 patients completed treatment. In the primary analysis (intent-to-treat missing = failure at week 48, 34% of patients (23/67; 95% CI: 23%-47% had plasma HIV-1 RNA 3. Although self-reported adherence appeared high, there were high levels of missing data and adherence results should be treated with caution. No new safety issues were identified. Conclusions Levels of missing data were high in this difficult-to-treat population, but potent antiretroviral suppression was achieved in a substantial proportion of HIV-infected IVDU-patients.

    Full Text Available Abstract Background South Africa’s antiretroviral programme is governed by defined national plans, establishing treatment targets and providing funding through ring-fenced conditional grants. However, in terms of the country’s quasi-federal constitution, provincial governments bear the main responsibility for provision of health care, and have a certain amount of autonomy and therefore choice in the way their HIV/AIDS programmes are implemented. Methods The paper is a comparative case study of the early management of ART scale up in three South African provincial governments – Western Cape, Gauteng and Free State – focusing on both operational and strategic dimensions. Drawing on surveys of models of ART care and analyses of the policy process conducted in the three provinces between 2005 and 2007, as well as a considerable body of grey and indexed literature on ART scale up in South Africa, it draws links between implementation processes and variations in provincial ART coverage (low, medium and high achieved in the three provinces. Results While they adopted similar chronic disease care approaches, the provinces differed with respect to political and managerial leadership of the programme, programme design, the balance between central standardisation and local flexibility, the effectiveness of monitoring and evaluation systems, and the nature and extent of external support and programme partnerships. Conclusions This case study points to the importance of sub-national programme processes and the influence of factors other than financing or human resource capacity, in understanding intervention scale up.

    Full Text Available Introduction: First antiretroviral therapy (ART is often switched to simpler, more potent or better tolerated regimens (1, 2. Although discontinuation rates are frequently studied, the durability of regimens is rarely approached. Materials and Methods: Retrospective study with the following objectives: analyze first ART schemes and their durability in naive patients with chronic HIV-1 and 2 infections, evaluate factors influencing ART change, second-line ART and consequent virologic and immunologic responses. Patients had follow-ups in a Central University Hospital, started ART between January 2007 and December 2012 and changed first regimens. Clinical data was obtained from medical records and analyzed using the Statistical Package for the Social Sciences (version 20. Results: Of the 652 naive patients who started ART, 164 changed regimens. The majority had HIV-1 infection (n=158. The mean age was 43.9 years (standard deviation±14.3, with a male predominance of 57.9%. Regimens with efavirenz were the most common amongst HIV-1 patients (50% followed by lopinavir/r (22%. In HIV-2 patients, lopinavir/r (n=3 regimens were most prevalent. First ART regimens had a mean duration of 12.1 months. There was no difference between NNRTI (59.8% and protease inhibitor (40.2% schemes regarding durability. Adverse reactions were the major cause of ART switching (55.5% followed by therapy resistance (12.1%.

    2014-11-01

    Full Text Available Introduction: In other disease areas, generic drugs are normally used after patent expiry. Patents on zidovudine, lamivudine, nevirapine and efavirenz have already expired. Patents will expire for abacavir in late 2014, lopinavir/r in 2016, and tenofovir, darunavir and atazanavir in 2017. However, patents on single-tablet regimens do not expire until after 2026. Methods: The number of people taking each antiretroviral in the UK was estimated from 23,655 individuals in the UK CHIC cohort (2012 database. Costs of patented drugs were taken from the British National Formulary database, assuming a 30% discount. Costs of generic antiretrovirals were estimated using an 80% discount from patented prices, or actual costs where available. Two options were analysed: 1 – all patients use single-tablet regimens and patented versions of drugs; prices remain stable over time; 2 – all people switch from patented to generic drugs when available, after patent expiry (dates shown above. Results: There were an estimated 67,000 people taking antiretrovirals in the UK in 2014, estimated to rise by 8% per year until 2018 (in line with previous rises. The most widely used antiretrovirals in the CHIC cohort were tenofovir (TDF (75%, emtricitabine (FTC (69%, efavirenz (EFV (39%, lamivudine (3TC (23%, abacavir (ABC (18%, darunavir (DRV (21% and atazanavir (ATV (16%. The predicted annual UK cost of generic ABC/3TC/EFV (three generic tablets once daily was £1018 per person-year. Costs of patented single-tablet regimens ranged from £5000 to £7500 per person-year. Assuming continued use of patented antiretrovirals in the UK, the predicted total national costs of antiretroviral treatment were predicted to rise from £425 million in 2014 to £459 m in 2015, £495 m in 2016, £536 m in 2017 and £578 m in 2018. With a 100% switch to generics, total predicted costs were £337 m in 2014, £364 m in 2015, £382 m in 2016, £144 m in 2017 and £169 m in 2018. The total

    Background WHO recommends that stavudine is phased out of antiretroviral therapy (ART) programmes and replaced with tenofovir (TDF) for first-line treatment. In this context, the Integrated HIV Care Program, Myanmar, evaluated patients for ART failure using HIV RNA viral load (VL) before making the change. We aimed to determine prevalence and determinants of ART failure in those on first-line treatment. Methods Patients retained on stavudine-based or zidovudine-based ART for >12 months with no clinical/immunological evidence of failure were offered VL testing from August 2012. Plasma samples were tested using real time PCR. Those with detectable VL>250 copies/ml on the first test were provided with adherence counseling and three months later a second test was performed with >1000 copies/ml indicating ART failure. We calculated the prevalence of ART failure and adjusted relative risks (aRR) to identify associated factors using log binomial regression. Results Of 4934 patients tested, 4324 (87%) had an undetectable VL at the first test while 610 patients had a VL>250 copies/ml. Of these, 502 had a second VL test, of whom 321 had undetectable VL and 181 had >1000 copies/ml signifying ART failure. There were 108 who failed to have the second test. Altogether, there were 94% with an undetectable VL, 4% with ART failure and 2% who did not follow the VL testing algorithm. Risk factors for ART failure were age 15–24 years (aRR 2.4, 95% CI: 1.5–3.8) compared to 25–44 years and previous ART in the private sector (aRR 1.6, 95% CI: 1.2–2.2) compared to the public sector. Conclusions This strategy of evaluating patients on first-line ART before changing to TDF was feasible and identified a small proportion with ART failure, and could be considered by HIV/AIDS programs in Myanmar and other countries.

    Recent research has demonstrated how antiretrovirals (ARVs) could be effective in the prevention of sexually transmitted HIV. We review research on the acceptability of oral pre-exposure prophylaxis (PrEP) and treatment as prevention (TasP) for HIV prevention amongst potential users. We consider with whom, where and in what context this research has been conducted, how acceptability has been approached, and what research gaps remain. Findings from 33 studies show a lack of TasP research, PrEP studies which have focused largely on men who have sex with men (MSM) in a US context, and varied measures of acceptability. In order to identify when, where and for whom PrEP and TasP would be most appropriate and effective, research is needed in five areas: acceptability of TasP to people living with HIV; motivation for PrEP use and adherence; current perceptions and management of risk; the impact of broader social and structural factors; and consistent definition and operationalisation of acceptability which moves beyond adherence.

    Full Text Available Abstract Background Little is known about the costs of HIV care in Ethiopia. Objective To estimate the average per person year (PPY cost of care for HIV patients with and without anti-retroviral therapy (ART in a district hospital. Methods Data on costs and utilization of HIV-related services were taken from Arba Minch Hospital (AMH in southern Ethiopia. Mean annual outpatient and inpatient costs and corresponding 95% confidence intervals (CI were calculated. We adopted a district hospital perspective and focused on hospital costs. Findings PPY average (95% CI costs under ART were US$235.44 (US$218.11–252.78 and US$29.44 (US$24.30–34.58 for outpatient and inpatient care, respectively. Estimates for the non-ART condition were US$38.12 (US$34.36–41.88 and US$80.88 (US$63.66–98.11 for outpatient and inpatient care, respectively. The major cost driver under the ART scheme was cost of ART drugs, whereas it was inpatient care and treatment in the non-ART scheme. Conclusion The cost profile of ART at a district hospital level may be useful in the planning and budgeting of implementing ART programs in Ethiopia. Further studies that focus on patient costs are warranted to capture all patterns of service use and relevant costs. Economic evaluations combining cost estimates with clinical outcomes would be useful for ranking of ART services.

    HIV/AIDS has been an extremely difficult pandemic to control. However, with the advent of antiretroviral therapy (ART), HIV has now been transformed into a chronic illness in patients who have continued treatment access and excellent long-term adherence. Existing indications for ART initiation in asymptomatic patients were based on CD4 levels; however, recent evidence has broken the shackles of CD4 levels. Early initiation of ART in HIV patients irrespective of CD4 counts can have profound positive impact on morbidity and mortality. Early initiation of ART has been found not only beneficial for patients but also to community as it reduces the risk of transmission. There have been few financial concerns about providing ART to all HIV-positive people but various studies have proven that early initiation of ART not only proves to be cost-effective but also contributes to economic and social growth of community. A novel multidisciplinary approach with early initiation and availability of ART at its heart can turn the tide in our favor in future. Effective preexposure prophylaxis and postexposure prophylaxis can also lower transmission risk of HIV in community. New understanding of HIV pathogenesis is opening new vistas to cure and prevention. Various promising candidate vaccines and drugs are undergoing aggressive clinical trials, raising optimism for an ever-elusive cure for HIV. This review describes various facets of tectonic shift in management of HIV. PMID:26900224

    Full Text Available Abstract Background Targeted outreach, counselling, and treatment of sexually transmitted infections (STIs are among the most cost-effective interventions aimed at ameliorating the burden of HIV/STIs. Since many new HIV infections occur in people under the age of 25, youth, and especially most at risk adolescents (MARA, need to be able to access HIV/STI services. Starting in 2006, a programme targeting MARA including outreach, confidential and voluntary counselling and testing, and STI diagnosis and treatment was piloted in three cities in Tajikistan. This study uses data from these pilot sites to estimate the costs of a national programme. Methods Cost data were collected from the three pilot sites. Then, the target population and the number of patients receiving specific types of services are calculated for other areas. The unit costs from the pilot sites are multiplied by usage rates to determine the total costs of a national programme. Scenarios were developed to reflect data uncertainty. The government's ability to finance the programme was estimated using Ministry of Health budget data. Further analyses were done for one of the pilot cities where more detailed data were available. Results In total, costs were projected for eight programme sites, covering an estimated 8,020 MARA. Operational and variable cost for the programme are projected to be US$ 119,159 (range US$ 104,953 to 151,524 per year. Including annual equivalent cost for capital and start-up items raises this to US$ 137,082 (range: US$ 123,022 to 169,597 per year. The analyses of potential sources of financing for the programme remain inconclusive, but it may take multiple sources of financing to fund the programme. Conclusion While the cost-effectiveness of similar programmes have been previously assessed using modelled data, more work needs to be done to assess the costs of new programmes in relation to financial resources available. Full costing should consider cost

    Full Text Available Abstract Background Health Related Quality of Life (HRQoL is an important outcome in times of Highly Active Antiretroviral Treatment (HAART. We compared the HRQoL of HIV positive patients receiving HAART with those awaiting treatment in public sector facilities in the Free State province in South Africa. Methods A stratified random sample of 371 patients receiving or awaiting HAART were interviewed and the EuroQol-profile, EuroQol-index and Visual Analogue Scale (VAS were compared. Independent associations between these outcomes and HAART, socio-demographic, clinical and health service variables were estimated using linear and ordinal logistic regression, adjusted for intra-clinic clustering of outcomes. Results Patients receiving HAART reported better HRQoL for 3 of the 5 EuroQol-dimensions, for the VAS score and for the EuroQol index in bivariable analysis. They had a higher mean EuroQol index (0.11 difference, 95% confidence interval [CI] 0.04; 0.23, and were more likely to have a higher index (odds ratio 1.9, 95% CI 1.1; 1.3, compared to those awaiting HAART, in multivariate analysis. Higher mean VAS scores were reported for patients who were receiving HAART (6.5 difference, 95% CI 1.3; 11.7, were employed (9.1, 95% CI 4.3; 13.7 or were female (4.7, 95% CI 0.79; 8.5. Conclusion HAART was associated with improved HRQoL in patients enrolled in a public sector treatment program in South Africa. Our finding that the EuroQol instrument was sensitive to HAART supports its use in future evaluation of HIV/AIDS care in South Africa. Longitudinal studies are needed to evaluate changes in individuals' HRQoL.

    Full Text Available Abstract Background In Denmark, it has recently become mandatory for all dairy farmers with more than 100 cows to sign up for a herd health programme. Three herd health programmes are available. These differ in a number of aspects, including the frequency of veterinary visits and the farmer’s access to prescription drugs. The objective of this study was to investigate whether dairy farmers’ behavioural intentions, i.e. to call a veterinarian or start medical treatment on the day that they detect a cow with mild clinical mastitis (MCM, are different depending on the type of herd health programme. Methods A questionnaire survey based on the Theory of Planned Behaviour (TPB was conducted. TPB proposes that a person’s behavioural intention is strongly correlated with his or her actual behaviour. Three behavioural factors determine the behavioural intention: attitude, subjective norm and perceived behavioural control. Each of these factors is decided by a set of beliefs, each of which in turn is weighted by an evaluation: 1 the expected outcomes of performing the behaviour, 2 what a person believes that others think of the behaviour, and 3 the person’s perceived power to influence the behaviour. A set of statements about the treatment of MCM based on interviews with 38 dairy farmers were identified initially. The statements were rephrased as questions and the resulting questionnaire was distributed to 400 randomly selected Danish dairy farmers who use the two most restrictive herd health programmes, either Core or Module1, and to all 669 farmers with the least restrictive herd health programme, Module2. The association between intention and the herd health programme was modelled using logistic regression. Results The farmers with the Module2 herd health programme had a significantly higher behavioural intention to perform the behaviour, when compared to farmers with a more restrictive herd health programme (OR = 2.1, p Conclusion Danish dairy

    Full Text Available Abstract Background Prompt access to effective treatment is central in the fight against malaria. However, a variety of interlinked factors at household and health system level influence access to timely and appropriate treatment and care. Furthermore, access may be influenced by global and national health policies. As a consequence, many malaria episodes in highly endemic countries are not treated appropriately. Project The ACCESS Programme aims at understanding and improving access to prompt and effective malaria treatment and care in a rural Tanzanian setting. The programme's strategy is based on a set of integrated interventions, including social marketing for improved care seeking at community level as well as strengthening of quality of care at health facilities. This is complemented by a project that aims to improve the performance of drug stores. The interventions are accompanied by a comprehensive set of monitoring and evaluation activities measuring the programme's performance and (health impact. Baseline data demonstrated heterogeneity in the availability of malaria treatment, unavailability of medicines and treatment providers in certain areas as well as quality problems with regard to drugs and services. Conclusion The ACCESS Programme is a combination of multiple complementary interventions with a strong evaluation component. With this approach, ACCESS aims to contribute to the development of a more comprehensive access framework and to inform and support public health professionals and policy-makers in the delivery of improved health services.

    Full Text Available Introduction: HIV care and treatment programmes worldwide are transforming as they push to deliver universal access to essential prevention, care and treatment services to persons living with HIV and their communities. The characteristics and capacity of these HIV programmes affect patient outcomes and quality of care. Despite the importance of ensuring optimal outcomes, few studies have addressed the capacity of HIV programmes to deliver comprehensive care. We sought to describe such capacity in HIV programmes in seven regions worldwide. Methods: Staff from 128 sites in 41 countries participating in the International epidemiologic Databases to Evaluate AIDS completed a site survey from 2009 to 2010, including sites in the Asia-Pacific region (n=20, Latin America and the Caribbean (n=7, North America (n=7, Central Africa (n=12, East Africa (n=51, Southern Africa (n=16 and West Africa (n=15. We computed a measure of the comprehensiveness of care based on seven World Health Organization-recommended essential HIV services. Results: Most sites reported serving urban (61%; region range (rr: 33–100% and both adult and paediatric populations (77%; rr: 29–96%. Only 45% of HIV clinics that reported treating children had paediatricians on staff. As for the seven essential services, survey respondents reported that CD4+ cell count testing was available to all but one site, while tuberculosis (TB screening and community outreach services were available in 80 and 72%, respectively. The remaining four essential services – nutritional support (82%, combination antiretroviral therapy adherence support (88%, prevention of mother-to-child transmission (PMTCT (94% and other prevention and clinical management services (97% – were uniformly available. Approximately half (46% of sites reported offering all seven services. Newer sites and sites in settings with low rankings on the UN Human Development Index (HDI, especially those in the President's Emergency

  12. Patient's perception, compliance to treatment and health education of antiretroviral therapy among HIV patients at a tertiary healthcare setting

    International Nuclear Information System (INIS)

    Objective: To illustrate perceptions, compliance to treatment and satisfaction levels regarding health education services pertaining to the anti-retrovival therapy among HIV and AIDS patients. Methods: The cross-sectional survey was carried out at the HIV Treatment Centre, Pakistan Institute of Medical Sciences (PIMS), Islamabad, from September 2009 to February 2010 in which patients were interviewed separately regarding their perceptions, compliance to treatment and satisfaction levels regarding health education services pertaining to the anti-retrovival therapy. All data collected was entered into SPSS version 15.0. The data was re-validated and analysed. Results: One hundred and forty patients were interviewed; there were 99 (70.7%) males.. Of the total, 28 (20%) had no knowledge about the beneficial effects of the therapy, and 45 (32 %) ranked health education services extremely beneficial in understanding the anti-retrovival therapy. Conclusion: While a significant proportion of patients considered ART either somewhat beneficial or beneficial in treating their ailment, they were unclear about the impact of health education provided at the treatment centre and different forms of print media.

    Full Text Available Abstract Background In resource-poor settings, mortality is at its highest during the first 3 months after combination antiretroviral treatment (cART initiation. A clear predictor of mortality during this period is having a low CD4 count at the time of treatment initiation. The objective of this study was to evaluate the effect on survival and clinic retention of a nurse-based rapid assessment clinic for high-risk individuals initiating cART in a resource-constrained setting. Methods The USAID-AMPATH Partnership has enrolled more than 140,000 patients at 25 clinics throughout western Kenya. High Risk Express Care (HREC provides weekly or bi-weekly rapid contacts with nurses for individuals initiating cART with CD4 counts of ≤100 cells/mm3. All HIV-infected individuals aged 14 years or older initiating cART with CD4 counts of ≤100 cells/mm3 were eligible for enrolment into HREC and for analysis. Adjusted hazard ratios (AHRs control for potential confounding using propensity score methods. Results Between March 2007 and March 2009, 4,958 patients initiated cART with CD4 counts of ≤100 cells/mm3. After adjusting for age, sex, CD4 count, use of cotrimoxazole, treatment for tuberculosis, travel time to clinic and type of clinic, individuals in HREC had reduced mortality (AHR: 0.59; 95% confidence interval: 0.45-0.77, and reduced loss to follow up (AHR: 0.62; 95% CI: 0.55-0.70 compared with individuals in routine care. Overall, patients in HREC were much more likely to be alive and in care after a median of nearly 11 months of follow up (AHR: 0.62; 95% CI: 0.57-0.67. Conclusions Frequent monitoring by dedicated nurses in the early months of cART can significantly reduce mortality and loss to follow up among high-risk patients initiating treatment in resource-constrained settings.

    Full Text Available Introduction: Most paediatric antiretroviral treatments (ARTs in Thailand are limited to tertiary care hospitals. To decentralize paediatric HIV treatment and care, Chiangrai Prachanukroh Hospital (CRH strengthened a provincial paediatric HIV care network by training community hospital (CH care teams to receive referrals of children for community follow-up. In this study, we assessed factors associated with death and clinical outcomes of HIV-infected children who received care at CRH and CHs after implementation of a community-based paediatric HIV care network. Methods: Clinical records were abstracted for all children who initiated ART at CRH. Paired Wilcoxon signed rank tests were used to assess CD4% and virological change among all children. Cox proportional hazard models were used to assess factors associated with death. Treatment outcomes (CD4%, viral load (VL and weight-for-age Z-score (WAZ were compared between CRH and CH children who met the criteria for analysis. Results: Between February 2002 and April 2008, 423 HIV-infected children initiated ART and 410 included in the cohort analysis. Median follow-up for the cohort was 28 months (interquartile range (IQR=12 to 42; 169 (41% children were referred for follow-up at CH. As of 31 March 2008, 42 (10% children had died. Baseline WAZ (<−2 (p=0.001 and baseline CD4% (<5% (p=0.015 were independently associated with death. At 48 months, 86% of ART-naïve children in follow-up had VL<400 copies/ml. For sub-group analysis, 133 children at CRH and 154 at CHs were included for comparison. Median baseline WAZ was lower in CH children than in CRH children (p=0.001; in both groups, WAZ, CD4% and VL improved after ART with no difference in rate of WAZ and CD4% gain (p=0.421 and 0.207, respectively. Conclusions: Children at CHs had more severe immunological suppression and low WAZ at baseline. Community- and tertiary care-based paediatric ART follow-ups result in equally beneficial outcomes with the

    Full Text Available BACKGROUND: Facing the dual burden of invasive cervical cancer and HIV in sub-Saharan Africa, the identification of preventable determinants of Cervical Intraepithelial Neoplasia (CIN in HIV-infected women is of paramount importance. METHODS: A cervical cancer screening based on visual inspection methods was proposed to HIV-infected women in care in Abidjan, Côte d'Ivoire. Positively screened women were referred for a colposcopy to a gynaecologist who performed directed biopsies. RESULTS: Of the 2,998 HIV-infected women enrolled, 132 (4.4% CIN of any grade (CIN+ were identified. Women had been followed-up for a median duration of three years [IQR: 1-5] and 76% were on antiretroviral treatment (ART. Their median most recent CD4 count was 452 [IQR: 301-621] cells/mm3. In multivariate analysis, CIN+ was associated with a most recent CD4 count >350 cells/mm3 (OR: 0.3; 95% CI: 0.2-0.6 or ≥200-350 cells/mm3 (OR 0.6; 95% CI 0.4-1.0 (Ref: <200 cells/mm3 CD4 (p<10-4. CONCLUSIONS: The presence of CIN+ is less common among HIV-infected women with limited or no immune deficiency. Despite the potential impact of immunological recovery on the reduction of premalignant cervical lesions through the use of ART, cervical cancer prevention, including screening and vaccination remains a priority in West Africa while ART is rolled-out.

    The relationship between quality of life (QoL) and antiretroviral treatment (ART) has mainly been studied using quantitative scales often not appropriate for use in other contexts and without taking peoples' lived experiences into consideration. Sub-Saharan Africa has the highest incidence of HIV and AIDS yet there is paucity in research done on QoL. This research report is intended to give an account of the use of a mixed method convergent parallel design as a novice approach to evaluate an instrument's context specificity, appropriateness and usefulness in another context for which it was designed. Data were collected through a qualitative exploration of the experiences of QoL of people living with HIV or AIDS (PLHA) in Africa since being on ART, as well as the quantitative measurements obtained from the HIV/AIDS-targeted quality of life (HAT-QoL) instrument. This study was conducted in three African countries. Permission and ethical approval to conduct the study were obtained. Purposive voluntary sampling was used to recruit PLHA through mediators working in community-based HIV/AIDS organisations and health clinics. Interviews were analysed through open coding and the quantitative data through descriptive statistics and the Cronbach's alpha coefficient. A much wider range and richness of experiences were expressed than measured by the HAT-QoL instrument. Although an effective instrument for use in the USA, it was found not to be sensitive, appropriate and useful in an African context in its present form. The recommendations focus on adapting the instrument using the data from the in-depth interviews or to develop a context-sensitive instrument that could measure QoL of PLHA in Africa.

    Background Therapeutic HIV vaccines may prove helpful to intensify antiretroviral treatment (ART) efficacy and may be an integral part of future cure strategies. Methods We examined IFN-gamma ELISpot responses to a panel of 218 HIV clade B consensus-based HIV protease-reverse transcriptase peptides, designed to mimic previously described and predicted cytotoxic T lymphocyte epitopes overlapping drug resistance (DR) positions, that either included the consensus sequence or the DR variant sequence, in 49 ART-naïve HIV-infected individuals. Next generation sequencing was used to assess the presence of minority DR variants in circulating viral populations. Results Although a wide spectrum of differential magnitudes of response to DR vs. WT peptide pairs was observed, responses to DR peptides were frequent and strong in the study cohort. No difference between the median magnitudes of response to DR vs. WT peptides was observed. Interestingly, of the 22 peptides that were recognized by >15% of the participants, two-thirds (64%) corresponded to DR peptides. When analysing responses per peptide pair per individual, responses to only WT (median 4 pairs/individual) or DR (median 6 pairs/individual) were more common than responses to both WT and DR (median 2 pairs/individual; p<0.001). While the presence of ELISpot responses to WT peptides was frequently associated with the presence of the corresponding peptide sequence in the patient’s virus (mean 68% of cases), responses to DR peptides were generally not associated with the presence of DR mutations in the viral population, even at low frequencies (mean 1.4% of cases; p = 0.0002). Conclusions Our data suggests that DR peptides are frequently immunogenic and raises the potential benefit of broadening the antigens included in a therapeutic vaccine approach to immunogenic epitopes containing common DR sequences. Further studies are needed to assess the quality of responses elicited by DR peptides. PMID:26808823

    Full Text Available OBJECTIVE: To compare the rate of decline of renal function in tenofovir- and abacavir-based antiretroviral therapy (ART in low-body weight treatment-naïve patients with HIV infection. DESIGN: We conducted a single-center retrospective cohort study of 503 Japanese patients who commenced on either tenofovir- or abacavir-based initial ART. METHODS: The incidence of renal dysfunction, defined as more than 25% fall in estimated glomerular filtration rate (eGFR from the baseline, was determined in each group. The effect of tenofovir on renal dysfunction was estimated by univariate and multivariate Cox hazards models as the primary exposure. Changes in eGFR until 96 weeks were estimated in both groups with a repeated measures mixed model. RESULTS: The median body weight of the cohort was 64 kg. The estimated incidence of renal dysfunction in the tenofovir and the abacavir arm was 9.84 per 100 and 4.55 per 100 person-years, respectively. Tenofovir was significantly associated with renal dysfunction by univariate and multivariate analysis (HR = 1.747; 95% CI, 1.152-2.648; p = 0.009 (adjusted HR = 2.080; 95% CI, 1.339-3.232; p68 kg: adjusted HR = 0.997; 95%CI, 0.318-3.121; p = 0.995. The fall in eGFR was significantly greater in the tenofovir arm than the abacavir arm after starting ART (p = 0.003. CONCLUSION: The incidence of renal dysfunction in low body weight patients treated with tenofovir was twice as high as those treated with abacavir. Close monitoring of renal function is recommended for patients with small body weight especially those with baseline body weight <60 kg treated with tenofovir.

    Full Text Available Este artigo trata dos constrangimentos institucionais que têm afetado a política brasileira de provisão de medicamentos contra a Aids. É analisado o conflito normativo observado na política de Aids entre as regras internacionais da propriedade intelectual, em especial a proteção de patentes, e a orientação de acesso universal e gratuito a medicamentos, que norteia a política brasileira. Esses constrangimentos não têm tido sucesso em alterar a configuração distributiva da política pública brasileira; contudo, vêm alterando as condições de sustentabilidade da política pública. Considerando que a principal barreira para a produção de medicamentos protegidos por patente é institucional e não tecnológica, o governo brasileiro tem enfrentado o dilema da tomada de decisão entre a manutenção da regra de monopólio ou o incentivo à competitividade que permita o posicionamento eficiente dos produtores nacionais e dos países emergentes.This paper addresses institutional constraints that have affected Brazilian politics regarding provision of anti-retroviral treatment (ART to HIV/Aids patients. We analyzed the normative conflict resulting from international agreements on intellectual property rights, especially patent protection, and the constitutional rights of Brazilian patients to universal and free access to ART. These constraints have not substantially changed the Brazilian public policy yet, but they may impact the future sustainability of this policy. As the main barrier to the production of patented drugs is not technological but institutional, Brazilian government faces a dilemma. It may either abide by existing monopolistic restrictions or it may incite competitiveness of domestic industries and developing countries in the pharmaceutical market.

    Full Text Available BACKGROUND AND AIMS: Liver stiffness measurement (LSM using transient elastography (Fibroscan® can identify individuals with potential underlying liver disease. We evaluated the prevalence of abnormal LSM values as assessed using LSM and its predictors in HIV-infected asymptomatic patients receiving combined antiretroviral treatment (cART without HBV/HCV coinfection. METHODS: We prospectively recruited 93 patients who had consistently been undergoing cART for more than 12 months at Severance Hospital in Seoul, Republic of Korea, from June to December 2010. LSM values >5.3 kPa were defined as abnormal. RESULTS: Thirty-nine (41.9% had abnormal LSM values. On multivariate correlation analysis, the cumulative duration of boosted and unboosted protease inhibitors (PIs were the independent factors which showed a negative and positive correlation to LSM values, respectively (β = -0.234, P = 0.023 and β = 0.430, P<0.001. In multivariate logistic regression analysis, the cumulative exposure duration of boosted-PIs and γ-glutamyltranspeptidase levels were selected as the independent predictors which showed a negative and positive correlation with abnormal LSM values, respectively (odds ratio [OR], 0.941; 95% confidence interval [CI], 0.889-0.997; P = 0.039 and OR, 1.032; 95% CI, 1.004-1.060; P = 0.023. CONCLUSION: The high percentage of HIV-infected asymptomatic patients receiving cART without HBV/HCV coinfection had abnormal LSM values. The cumulative exposure duration of boosted-PIs and γ-GT level were independent predictors which showed a negative and positive correlation with abnormal LSM values, respectively.

    Full Text Available Abstract Background South Africa has an estimated 1.5 million persons in need of antiretroviral therapy (ART. In 2004, the South African government began collaborating with the United States President's Emergency Plan for AIDS Relief (PEPFAR to increase access to ART. We determined how PEPFAR treatment support changed from 2005-2009. Methods In order to describe the change in number and type of PEPFAR-supported ART facilities, we analyzed routinely collected program-monitoring data from 2005-2009. The collected data included the number, type and province of facilities as well as the number of patients receiving ART at each facility. Results The number of PEPFAR-supported facilities providing ART increased from 184 facilities in 2005 to 1,469 facilities in 2009. From 2005-2009 the number of PEPFAR-supported government facilities increased 10.1 fold from 54 to 546 while the number of PEPFAR-supported NGO facilities (including general practitioner and NGO facilities increased 6.2 fold from 114 to 708. In 2009 the total number of persons treated at PEPFAR-supported NGO facilities was 43,577 versus 501,089 persons at PEPFAR-supported government facilities. Overall, the median number of patients receiving ART per site increased from 81 in 2005 to 136 in 2009. Conclusions To mitigate the gap between those needing and those receiving ART, more facilities were supported. The proportion of government facilities supported and the median number of persons treated at these facilities increased. This shift could potentially be sustainable as government sites reach more individuals and receive government funding. These results demonstrate that PEPFAR was able to support a massive scale-up of ART services in a short period of time.

    Full Text Available BACKGROUND: Given the immense burden of HIV/AIDS on health systems in sub-Saharan Africa and the intricate link between HIV/AIDS and mental health problems, health care providers need a valid and reliable instrument to assess mental health rapidly. The Hospital Anxiety and Depression Scale (HADS may constitute such an instrument. The aims of this study were to: (1 examine the factor structure of the HADS in a population of South African HIV/AIDS patients on antiretroviral treatment (ART; and (2 identify and control the disturbing influence of systematic wording effects in vulnerable respondent groups. METHODOLOGY/PRINCIPAL FINDINGS: The translated scale was administered to 716 HIV/AIDS patients enrolled in the public sector ART program in South Africa. A combined confirmatory factor analysis and correlated-traits-correlated-methods framework was used to determine the preferred factor structure of the HADS, while controlling for the disturbing influence of systematic wording effects. When assessing the structure without a negative wording factor, all three factor structures displayed an acceptable fit to the data. The three-factor solution best fitted the data. Addition of a method factor significantly improved the fit of all three factor solutions. Using χ(2 difference testing, Razavi's one-factor solution displayed a superior fit compared to the other two factor solutions. CONCLUSIONS: The study outcomes support the use of the HADS as a valid and reliable means to screen for mental health problems in HIV/AIDS patients enrolled in a public-sector ART program in a resource-limited context. The results demonstrate the importance of evaluating and correcting for wording effects when examining the factor structure of the screening instrument in vulnerable patient groups. In light of the inter-relationships between HIV/AIDS and mental health problems and the scarcity of adequate screening tools, additional studies on this topic are required.

    In preparation for a proposed intervention at an antiretroviral therapy (ART) clinic in Durban, South Africa, we explored the dynamics and patterns of cellular phone use among this population, in order to ascertain whether clinic contact via patients' cellular phones was a feasible and acceptable modality for appointment reminders and adherence messages. Adults, who were more than 18 years old, ambulatory, and who presented for treatment at the clinic between October-December 2007, were consecutively recruited until the sample size was reached (n = 300). A structured questionnaire was administered, including questions surrounding sociodemographics, cellular phone availability, patterns of use, and acceptability of clinic contact for the purpose of clinic appointment reminders and adherence support. Most respondents (n = 242; 81%) reported current ownership of a cellular phone with 95% utilizing a prepaid airtime service. Those participants who currently owned a cellular phone reported high cellular phone turnover due to theft or loss (n = 94, 39%) and/or damage (n = 68, 28%). More females than men switched their cell phones off during the day (p = 0.002) and were more likely to not take calls in certain social milieus (p ≤ 0.0001). Females were more likely to share their cell phone with others (p = 0.002) or leave it in a place where someone could access it (p = 0.005). Most respondents were willing to have clinic contact via their cellular phones, either verbally (99%) or via text messages (96%). The use of cellular phones for intervention purposes is feasible and should be further investigated. The findings highlight the value of gender-based analyses in informing interventions.

    The Indian government provides free antiretroviral treatment (ART) for people living with HIV. To assist in developing policies and programs to advance equity in ART access, we explored barriers to ART access among kothis (men who have sex with men [MSM] whose gender expression is feminine) and aravanis (transgender women, also known as hijras) living with HIV in Chennai. In the last quarter of 2007, we conducted six focus groups and four key-informant interviews. Data were explored using framework analysis to identify categories and derive themes. We identified barriers to ART access at the family/social-level, health care system-level, and individual-level; however, we found these barriers to be highly interrelated. The primary individual-level barrier was integrally linked to the family/social and health care levels: many kothis and aravanis feared serious adverse consequences if their HIV-positive status were revealed to others. Strong motivations to keep one's HIV-positive status and same-sex attraction secret were interconnected with sexual prejudice against MSM and transgenders, and HIV stigma prevalent in families, the health care system, and the larger society. HIV stigma was present within kothi and aravani communities as well. Consequences of disclosure, including rejection by family, eviction from home, social isolation, loss of subsistence income, and maltreatment (although improving) within the health care system, presented powerful disincentives to accessing ART. Given the multi-level barriers to ART access related to stigma and discrimination, interventions to facilitate ART uptake should address multiple constituencies: the general public, health care providers, and the kothi and aravani communities. India needs a national policy and action plan to address barriers to ART access at family/social, health care system, and individual levels for aravanis, kothis, other subgroups of MSM and other marginalized groups.

    Full Text Available Abstract Background Treatment of feline immunodeficiency virus (FIV infection has been hampered by the absence of a specific combination antiretroviral treatment (ART. Integrase strand transfer inhibitors (INSTIs are emerging as a promising new drug class for HIV-1 treatment, and we evaluated the possibility of inhibiting FIV replication using INSTIs. Methods Phylogenetic analysis of lentiviral integrase (IN sequences was carried out using the PAUP* software. A theoretical three-dimensional structure of the FIV IN catalytic core domain (CCD was obtained by homology modeling based on a crystal structure of HIV-1 IN CCD. The interaction of the transferred strand of viral DNA with the catalytic cavity of FIV IN was deduced from a crystal structure of a structurally similar transposase complexed with transposable DNA. Molecular docking simulations were conducted using a genetic algorithm (GOLD. Antiviral activity was tested in feline lymphoblastoid MBM cells acutely infected with the FIV Petaluma strain. Circular and total proviral DNA was quantified by real-time PCR. Results The calculated INSTI-binding sites were found to be nearly identical in FIV and HIV-1 IN CCDs. The close similarity of primate and feline lentivirus IN CCDs was also supported by phylogenetic analysis. In line with these bioinformatic analyses, FIV replication was efficiently inhibited in acutely infected cell cultures by three investigational INSTIs, designed for HIV-1 and belonging to different classes. Of note, the naphthyridine carboxamide INSTI, L-870,810 displayed an EC50 in the low nanomolar range. Inhibition of FIV integration in situ was shown by real-time PCR experiments that revealed accumulation of circular forms of FIV DNA within cells treated with L-870,810. Conclusion We report a drug class (other than nucleosidic reverse transcriptase inhibitors that is capable of inhibiting FIV replication in vitro. The present study helped establish L-870,810, a compound

    Full Text Available Purpose of the study: Guidelines are based on clinical trial data as well as expert opinion and do not reflect economic considerations. Cost-efficacy analysis of recommended regimens allows for a ranking which takes into account both clinical and economic considerations. The aim of the present analysis was thus complement the information provided by the EACS (v6 guidelines regarding recommended initial treatment for HIV-1 infection. Methods: The methodology used was that described in Blasco et al. 2011 [1], but applied to Portugal in terms of (i resource prices, (ii resource utilization upon ART initiation, regimen switch and treatment of adverse events, and (iii subsequent regimen selection according to the initial regimen and the reason for switch. Regarding costs, the payer (National Healthcare Service perspective was considered taking into account only differential direct costs. The time horizon was 48 weeks. Summary of results: In this analysis, efficacy ranged from 66% with ABC/3TC+LPV/r to 86% for TDF/FTC+RAL. TDF/FTC+NVP was the least expensive regimen both in terms of the 48 weeks’ cost of the initial regimen and in terms of the total 48 weeks’ costs (i.e., including sequential therapy and other direct medical costs (7,592#x20AC;. Nonetheless, once cost and efficacy are considered simultaneously, TDF/FTC+NVP ranks third (11,419#x20AC;, ABC/3TC+EFV ranks second (11,073#x20AC; and TDF/FTC+EFV (also available, in a single tablet regimen ranks first (10,888#x20AC; indicating that this is the regimen yielding the lowest cost per suppressed patient. Among regimens containing boosted protease inhibitors, TDF/FTC+DRV/r was the regimen with the lowest cost/efficacy ratio (13,020#x20AC; and TDF/FTC+ATV/r had the highest ratio (15,102#x20AC;. Conclusions: Viral suppression is a relevant efficacy outcome not only due to individual benefits but also from a public health perspective.

    Background Tenofovir (TDF) can cause kidney injury through tubular dysfunction, with or without drop of estimated glomerular filtration rate (eGFR). Whether mild eGFR reductions during treatment should be considered a reason for prompt TDF discontinuation, however, remains unclear. Methods Patients with normal pre-TDF eGFR levels, who had developed mild renal impairment (i.e., two consecutive eGFR results between 89–60 ml/min) on TDF, were observed until onset of chronic kidney disease (CKD), defined as two eGFR6 months despite mild renal impairment, current TDF use was not associated with a significantly higher rate of CKD. Other significant predictors of CKD were older age, intravenous drug use, diabetes, hypertension, lower pre-TDF eGFR, higher eGFR drop since TDF introduction and longer exposure to TDF. Conclusions Prompt discontinuation of TDF among patients developing mild renal impairment may prevent further progression of renal damage. PMID:27632369

    Full Text Available Abstract Context Highly active antiretroviral treatment (HAART usage in India is escalating. With the government of India launching the free HAART rollout as part of the "3 by 5" initiative, many people living with HIV/AIDS (PLHA have been able to gain access to HAART medications. Currently, the national HAART centers are located in a few district hospitals (in the high- and medium-prevalence states and have very stringent criteria for enrolling PLHA. Patients who do not fit these criteria or patients who are too ill to undergo the prolonged wait at the government hospitals avail themselves of nongovernment organization (NGO services in order to take HAART medications. In addition, the government program has not yet started providing second-line HAART (protease inhibitors. Hence, even with the free HAART rollout, NGOs with the expertise to provide HAART continue to look for funding opportunities and other innovative ways of making HAART available to PLHA. Currently, no study from Indian NGOs has compared the direct and indirect costs of solely managing opportunistic infections (OIs vs HAART. Objective Compare direct medical costs (DMC and nonmedical costs (NMC with 2005 values accrued by the NGO and PLHA, respectively, for either HAART or exclusive OI management. Study design Retrospective case study comparison. Setting Low-cost community care and support center - Freedom Foundation (NGO, Bangalore, south India. Patients Retrospective analysis data on PLHA accessing treatment at Freedom Foundation between January 1, 2003 and January 1, 2005. The HAART arm included case records of PLHA who initiated HAART at the center, had frequent follow-up, and were between 18 and 55 years of age. The OI arm included records of PLHA who were also frequently followed up, who were in the same age range, who had CD4+ cell counts Results At 2005 costs, the median DMC plus NMC in the OI group was 21,335 Indian rupees (Rs (mean Rs 24,277/- per patient per year (pppy

    Full Text Available BACKGROUND: Highly active antiretroviral treatment (HAART programs have been associated with declines in the burden of invasive pneumococcal disease (IPD in industrialized countries. The aim of this study was to evaluate trends in IPD hospitalizations in HIV-infected adults in Soweto, South Africa, associated with up-scaling of the HAART program from 2003 to 2008. METHODS: Laboratory-confirmed IPD cases were identified from 2003 through 2008 through an existing surveillance program. The period 2003-04 was designated as the early-HAART era, 2005-06 as the intermediate-HAART era and 2007-08 as the established-HAART era. The incidence of IPD was compared between the early-HAART and established-HAART eras in HIV-infected and-uninfected individuals. RESULTS: A total of 2,567 IPD cases among individuals older than 18 years were reported from 2003 through 2008. Overall incidence of IPD (per 100,000 did not change during the study period in HIV-infected adults (207.4 cases in the early-HAART and 214.0 cases in the established-HAART era; p = 0.55. IPD incidence, actually increased 1.16-fold (95% CI: 1.01; 1.62 in HIV-infected females between the early-and established-HAART eras (212.1 cases and 246.2 cases, respectively; p = 0.03. The incidence of IPD remained unchanged in HIV-uninfected adults across the three time periods. CONCLUSION: Despite a stable prevalence of HIV and the increased roll-out of HAART for treatment of AIDS patients in our setting, the burden of IPD has not decreased among HIV-infected adults. The study indicates a need for ongoing monitoring of disease and HAART program effectiveness to reduce opportunistic infections in African adults with HIV/AIDS, as well as the need to consider alternate strategies including pneumococcal conjugate vaccine immunization for the prevention of IPD in HIV-infected adults.

    SummaryHighly active antiretroviral therapy has decreased the morbidity and mortality related to HIV infection, including oral opportunistic infections. This paper offers an analysis of the scientific literature on the epidemiological aspects of oral candidiasis in HIV-positive children in the combination antiretroviral therapy era. An electronic databases search was made covering the highly active antiretroviral therapy era (1998 onwards). The terms used were oral lesions, oral candidiasis and their combination with highly active antiretroviral therapy and HIV/AIDS children. The following data were collected from each paper: year and country in which the investigation was conducted, antiretroviral treatment, oral candidiasis prevalence and diagnostic parameters (clinical or microbiological). Prevalence of oral candidiasis varied from 2.9% in American HIV-positive children undergoing highly active antiretroviral therapy to 88% in Chilean HIV-positive children without antiretroviral therapy. With respect to geographical location and antiretroviral treatment, higher oral candidiasis prevalence in HIV-positive children on combination antiretroviral therapy/antiretroviral therapy was reported in African children (79.1%) followed by 45.9% reported in Hindu children. In HIV-positive Chilean children on no antiretroviral therapy, high oral candidiasis prevalence was reported (88%) followed by Nigerian children (80%). Oral candidiasis is still frequent in HIV-positive children in the highly active antiretroviral therapy era irrespective of geographical location, race and use of antiretroviral therapy.

The city of Cartagena de Indias, has favorable conditions for infectionwith HIV because of their status as tourist district and for being an epicenter of socialand demographic changes that are associated with an increased risk of HIV infection(4, however no studies have evaluated the effectiveness of antiretroviral treatment.Aim: To estimate effectiveness of six months of HAART therapy in HIV patients admittedto a treatment program in a health center of the city.Methods: Retrospective descriptive study that examined all patients assigned to theprogram for HIV / AIDS in the health center “Atencion integral” from January 2007 toJuly 2010. We studied demographic variables as sex, age, weight, body mass index,different antiretroviral schemes, CD4 count and viral load.Results: There were 167 patients assigned to the program. Nine cases wereexcluded for failing to adherence HAART and 96 for not having the reportof viral load before or after treatment. A total of 62 cases were analyzed.59.7% were male, average age was 35 years with standard deviation (SD of 9.4 years.49.5% of patients were 30 years or less, the minimum age was 20 and maximum of 58years.

    Full Text Available Abstract Background Funding for scaling-up antiretroviral treatment (ART in low-income countries has increased substantially, but the lack of human resources for health (HRH is increasingly being identified as an important constraint for scaling-up ART. Methods In a clinic run by Médecins Sans Frontières in Siem Reap, Cambodia, we documented the use of doctor-time for ART in September 2004 and in August 2005, for different phases in ART (pre-ART, ART initiation, ART follow-up Year 1, & ART follow-up Year 2. Based on these observations and using a variety of assumptions for survival of patients on ART (between 90 and 95% annually and for further reductions in doctor-time per patient (between 0 and 10% annually, we estimated the need for doctors for the period 2004 till 2013 in the Siem Reap clinic, and in a hypothetical district in sub-Saharan Africa. Results In the Siem Reap clinic, we found that from 2004 to 2005 the doctor-time needed per patient was reduced by between 14% and 33%, thanks to a reduction in number of visits per patient and shorter consultation times. In 2004, 2.06 full-time equivalent (FTE doctors were needed for 522 patients on ART, and in 2005 this was slightly reduced to 1.97 FTE doctors for 911 patients on ART. By 2013, Siem Reap clinic will need between 2 and 5 FTE doctors for ART. In a district in sub-Saharan Africa with 200,000 inhabitants and 20% adult HIV prevalence, using a similar doctor-based ART delivery model, between 4 and 11 FTE doctors would be needed to cover 50% of ART needs. Conclusion ART is labour intensive. Important reductions in doctor-time per patient can be realized during scaling-up. The doctor-based ART delivery model analysed seems adequate for Cambodia. However, for many districts in sub-Saharan Africa a doctor-based ART delivery model may be incompatible with their HRH constraints.

We used qualitative methods to explore the use, perceptions, and acceptability of RUSF among adult HIV patients in Jimma, Ethiopia. Methods: The study obtained data from direct observations and 24 in-depth interviews with HIV patients receiving RUSF. Results: Participants were generally very motivated to take RUSF and viewed it as beneficial. RUSF was described as a means to fill a nutritional gap, to “rebuild the body,” and protect it from harmful effects of antiretroviral treatment (ART. Many experienced nausea and vomiting when starting the supplement. This caused some to stop supplementation, but the majority adapted to RUSF. The supplement was eaten separately from meal situations and only had a little influence on household food practices. RUSF was described as food with “medicinal qualities,” which meant that many social and religious conventions related to food did not apply to it. The main concerns about RUSF related to the risk of HIV disclosure and its social consequences. Conclusion: HIV patients view RUSF in a context of competing livelihood needs. RUSF intake was motivated by a strong wish to get well, while the risk of HIV disclosure caused concerns. Despite the motivation for improving health, the preservation of social networks was prioritized, and nondisclosure was often a necessary strategy. Food sharing and religious

    Full Text Available Introduction: Nigeria has a high burden of children living with HIV and tuberculosis (TB. This article examines the magnitude of TB among children receiving antiretroviral treatment (ART, compares their ART outcomes with their non-TB counterparts and argues that addressing TB among children on ART is critical for achieving the 90–90–90 targets. Methods: This was a facility-based, retrospective analysis of medical records of children aged <15 years who were newly initiated on ART between 2011 and 2012. Structured tools were used to collect data. STATA software was used to perform descriptive, survival and multivariate analyses. Results: A total of 1142 children with a median age of 3.5 years from 20 selected facilities were followed for 24 months. Of these, 95.8% were assessed for TB at ART initiation and 14.7% had TB. Children on ART were more likely to have TB if they were aged 5 years or older (p<0.01 and had delayed ART initiation (p<0.05. The cotrimoxazole and isoniazid prophylaxes were provided to 87.9 and 0.8% of children, respectively. The rate of new TB cases was 3 (2.2–4.0 per 100 person-years at six months and declined to 0.2 (0.06–1.4 per 100 person-years at 24 months. TB infection [adjusted hazard ratio (aHR: 4.3; 2.3–7.9], malnutrition (aHR: 5.1; 2.6–9.8, delayed ART initiation (aHR: 3.2; 1.5–6.7 and age less than 1 year at ART initiation (aHR: 4.0; 1.4–12.0 were associated with death. Additionally, patients with TB (aHR: 1.3; 1.1–1.6 and children below the age of 1 at ART initiation (aHR: 2.9; 1.7–5.2 were more likely to be lost to follow-up (LFU. Conclusions: Children on ART with TB are less likely to survive and more likely to be LFU. These risks, along with low isoniazid uptake and delayed ART initiation, present a serious challenge to achieving the 90–90–90 targets and underscore an urgent need for inclusion of childhood TB/HIV in global plans and reporting mechanisms.

    Despite extensive prevention efforts, an estimated 21% of individuals with HIV/AIDS in the United States are unaware of their status, placing them at greater risk for spreading the virus to others. HIV treatment as prevention (TasP) is rapidly becoming an important public health strategy to reduce HIV transmission at the population level. Data for this study were collected on a sample of 11,397 HIV-positive individuals in the Ryan White system, a publicly funded system of care for HIV-positive individuals in Los Angeles County who are uninsured, in 2009 to examine two components of TasP: baseline rates and factors associated with antiretroviral therapy (ART) use and viral load (VL) suppression in a publicly funded system of care. ART coverage among our sample was 90%. In multivariate analyses, those with a higher odds of having unsuppressed VL included: females compared to males (adjusted odds ratio [AOR]=1.25; 95% confidence interval [CI]=1.06, 1.47); African Americans compared to whites (AOR=1.42; 95% CI=1.24, 1.62); men who have sex with men compared to heterosexuals (AOR=1.15; 95% CI=1.00, 1.32); recent substance abusers compared to nonsubstance abusers (AOR=1.35; 95% CI=1.17, 1.55); those recently incarcerated or ever incarcerated compared to those never incarcerated (AOR=1.37; 95% CI=1.15, 1.63; and AOR=1.28; 95% CI=1.09, 1.50); and those retained in care compared to those not retained in care (AOR=1.98; 95% CI=1.76, 2.22). Understanding the key sociodemographic, geographic and behavioral factors associated with ART use as well as HIV VL suppression will be useful for informing the development and deployment of targeted programming and policies that may further enhance the implementation of the TasP approach in communities across the United States.

    Full Text Available Rebecca Pavlos, Elizabeth J PhillipsInstitute for Immunology and Infectious Diseases, Murdoch University, Murdoch, Western Australia, AustraliaAbstract: Antiretroviral therapy (ART has evolved considerably over the last three decades. From the early days of monotherapy with high toxicities and pill burdens, through to larger pill burdens and more potent combination therapies, and finally, from 2005 and beyond where we now have the choice of low pill burdens and once-daily therapies. More convenient and less toxic regimens are also becoming available, even in resource-poor settings. An understanding of the individual variation in response to ART, both efficacy and toxicity, has evolved over this time. The strong association of the major histocompatibility class I allele HLA-B*5701 and abacavir hypersensitivity, and its translation and use in routine HIV clinical practice as a predictive marker with 100% negative predictive value, has been a success story and a notable example of the challenges and triumphs in bringing pharmacogenetics to the clinic. In real clinical practice, however, it is going to be the exception rather than the rule that individual biomarkers will definitively guide patient therapy. The need for individualized approaches to ART has been further increased by the importance of non-AIDS comorbidities in HIV clinical practice. In the future, the ideal utilization of the individualized approach to ART will likely consist of a combined approach using a combination of knowledge of drug, virus, and host (pharmacogenetic and pharmacoecologic [factors in the individual's environment that may be dynamic over time] information to guide the truly personalized prescription. This review will focus on our knowledge of the pharmacogenetics of the efficacy and toxicity of currently available antiretroviral agents and the current and potential utility of such information and approaches in present and future HIV clinical care.Keywords: HIV

    Full Text Available Abstract Background A major obstacle facing many lower-income countries in establishing and maintaining HIV treatment programmes is the scarcity of trained health care providers. To address this shortage, the World Health Organization has recommend task shifting to HIV-infected peers. Methods We designed a model of HIV care that utilizes HIV-infected patients, community care coordinators (CCCs, to care for their clinically stable peers with the assistance of preprogrammed personal digital assistants (PDAs. Rather than presenting for the standard of care, monthly clinic visits, in this model, patients were seen every three months in clinics and monthly by their CCCs in the community during the interim two months. This study was conducted in Kosirai Division, western Kenya, where eight of the 24 sub-locations (defined geographic areas within the division were randomly assigned to the intervention with the remainder used as controls. Prior to entering the field, CCCs underwent intensive didactic training and mentoring related to the assessment and support of HIV patients, as well as the use of PDAs. PDAs were programmed with specific questions and to issue alerts if responses fell outside of pre-established parameters. CCCs were regularly evaluated in six performance areas. An impressionistic analysis on the transcripts from the monthly group meetings that formed the basis of the continuous feedback and quality improvement programme was used to assess this model. Results All eight of the assigned CCCs successfully passed their training and mentoring, entered the field and remained active for the two years of the study. On evaluation of the CCCs, 89% of their summary scores were documented as superior during Year 1 and 94% as superior during Year 2. Six themes emerged from the impressionistic analysis in Year 1: confidentiality and "community" disclosure; roles and responsibilities; logistics; clinical care partnership; antiretroviral adherence; and

    The HIV epidemic in Vietnam is concentrated, with high prevalence estimates among injection drug users and commercial sex workers. Socio-demographics, substance use and clinical correlates of antiretroviral therapy non-adherence were studied in 100 HIV-1 infected drug users receiving antiretroviral therapy for at least 6 months in Hanoi, Vietnam. All study participants were men with a mean age of 29.9 ± 4.9 years. The median duration on antiretroviral therapy was 16.2 ± 12.7 months; 83% reported 'very good' or 'perfect' adherence in the past 30 days on a subjective one-item Likert scale at time of study enrollment; 48% of participants reported drug use within the previous 6 months, with 22% reporting current drug use. Injection drug use with or without non-injection drug use in the past 6 months (95% C.I. 2.19, 1.30-3.69) and years on antiretroviral therapy (95% C.I. 1.43, 1.14-1.78) were correlated with suboptimal adherence. These findings support Vietnam's ongoing scale-up of harm reduction programmes for injection drug users and their integration with antiretroviral therapy delivery. Moreover, results highlight the need to identify and implement new ways to support high levels of antiretroviral therapy adherence as duration on antiretroviral therapy increases.

    Introduction Young people with drug and alcohol problems are likely to have poorer health and other psychosocial outcomes than other young people. Residential treatment programmes have been shown to lead to improved health and related outcomes for young people in the short term. There is very little robust research showing longer term outcomes or benefits of such programmes. This paper describes an innovative protocol to examine the longer term outcomes and experiences of young people referred to a residential life management and treatment programme in Australia designed to address alcohol and drug issues in a holistic manner. Methods and analysis This is a mixed-methods study that will retrospectively and prospectively examine young people's pathways into and out of a residential life management programme. The study involves 3 components: (1) retrospective data linkage of programme data to health and criminal justice administrative data sets, (2) prospective cohort (using existing programme baseline data and a follow-up survey) and (3) qualitative in-depth interviews with a subsample of the prospective cohort. The study will compare findings among young people who are referred and (a) stay 30 days or more in the programme (including those who go on to continuing care and those who do not); (b) start, but stay fewer than 30 days in the programme; (c) are assessed, but do not start the programme. Ethics and dissemination Ethics approval has been sought from several ethics committees including a university ethics committee, state health departments and an Aboriginal-specific ethics committee. The results of the study will be published in peer-reviewed journals, presented at research conferences, disseminated via a report for the general public and through Facebook communications. The study will inform the field more broadly about the value of different methods in evaluating programmes and examining the pathways and trajectories of vulnerable young people. PMID

    Dickinson, Laura; Khoo, Saye; Back, David

    2010-01-01

    Current antiretroviral treatment has allowed HIV infection to become a chronic manageable condition with many HIV patients living longer. However, available antiretrovirals are not without limitations, for example the development of resistance and adverse effects. Consequently, new drugs in existing and novel classes are urgently required to provide viable treatment options to patients with few remaining choices. Darunavir, etravirine, maraviroc and raltegravir have been recently approved for treatment-experienced patients and other agents such as rilpivirine, vicriviroc and elvitegravir are currently under phase III study. Clinical studies are necessary to optimise potential treatment combinations and to manage drug-drug interactions to help avoid toxicity or therapy failure. This review aims to summarise the pharmacokinetics and key drug-drug interaction studies for newly available antiretrovirals and those in development. Further information regarding drug-drug interactions of well established antiretrovirals and those recently approved are readily available online at sites such as http://www.hiv-druginteractions.org, http://www.clinicaloptions.com/hiv, http://hivinsite.ucsf.edu. This article forms part of a special issue of Antiviral Research marking the 25th anniversary of antiretroviral drug discovery and development, Vol 85, issue 1, 2010.

Methods/Design The EVASYON was planned by a multidisciplinary team to treat OW/OB in Spanish adolescents. The EVASYON is a multi-centre study conducted in 5 hospitals in 5 Spanish cities (Granada, Madrid, Pamplona, Santander and Zaragoza and two hundred and four OW/OB Spanish adolescents were recruited for this intervention. The treatment was implemented for approximately one-year follow-up. The adolescents were treated in groups of a maximum of 10 subjects; each group had 20 visits during the treatment period in two phases: intensive during the first 2 months (1st to 9th visits, and extensive during the last 11 months (10th to 20th visits. In order to assess the efficacy of the treatment, 8 dimensions were measured: diet; physical activity and fitness; eating behaviour; body composition; haematological profile; metabolic profile; minerals and vitamins; immuno-inflammatory markers. Moreover, genetic polymorphisms were also determined. Discussion The treatment programme developed in the EVASYON study was designed as a national pilot study to be implemented as an effective treatment for adolescents with OW/OB into the Spanish Health Care Service.

    This cohort study was conducted to report on the incidence, timing and risk factors for stavudine (d4T)- and nevirapine (NVP)-related severe drug toxicity (requiring substitution) with a generic fixed-dose combination under program conditions in Kigali, Rwanda. Probability of 'time to first toxicity-related drug substitution' was estimated using the Kaplan-Meier method and Cox-proportional hazards modeling was used to identify risk factors. Out of 2190 adults (median follow-up: 1.5 years), d4T was replaced in 175 patients (8.0%) for neuropathy, 69 (3.1%) for lactic acidosis and 157 (7.2%) for lipoatrophy, which was the most frequent toxicity by 3 years of antiretroviral treatment (ART). NVP was substituted in 4.9 and 1.3% of patients for skin rash and hepatotoxicity, respectively. Use of d4T 40 mg was associated with increased risk of lipoatrophy and early (strategies.

In younger children, starting ART with lopinavir boosted with ritonavir (LPVr results in lower risk of virological failure, but data in children three years and older are scarce, and long-term ART with LPVr is problematic in resource-poor settings.Retrospective cohort of children three years and older who started triple ART including LPVr or a NNRTI between 2007 and 2013 in a rural setting in India. Children who started LPVr were switched to nevirapine-based ART after virological suppression. We analysed two outcomes, virological suppression (HIV-RNA 1000 copies/ml after virological suppression using Cox proportional hazard regression. A sensitivity analysis was performed using inverse probability of treatment weighting (IPTW based of propensity score methods.Of 325 children having a viral load during the first year of ART, 74/83 (89.2% in the LPVr group achieved virological suppression versus 185/242 (76.5% in the NNRTI group. In a multivariable analysis, the use of LPVr-based ART was associated with higher probability of virological suppression (adjusted odds ratio 3.19, 95% confidence interval [CI] 1.11-9.13. After IPTW, the estimated risk difference was 12.2% (95% CI, 2.9-21.5. In a multivariable analysis including 292 children who had virological suppression and available viral loads after one year of ART, children switched from LPVr to nevirapine did not have significant higher risk of virological failure (adjusted hazard ratio 1.18, 95% CI 0.36-3.81.In a cohort of HIV infected children three years and older in a resource-limited setting, an LPVr induction- nevirapine maintenance strategy resulted in more initial virological suppression and similar incidence of virological failure after initial virological suppression than NNRTI-based regimens.

    Full Text Available Antiretroviral therapy (ART has transformed HIV infection into a treatable, chronic condition. However, the need to continue treatment for decades rather than years, calls for a long-term perspective of ART. Adherence to the regimen is essential for successful treatment and sustained viral control. Studies have indicated that at least 95% adherence to ART regimens is optimal. It has been demonstrated that a 10% higher level of adherence results in a 21% reduction in disease progression. The various factors affecting success of ART are social aspects like motivation to begin therapy, ability to adhere to therapy, lifestyle pattern, financial support, family support, pros and cons of starting therapy and pharmacological aspects like tolerability of the regimen, availability of the drugs. Also, the regimen′s pill burden, dosing frequency, food requirements, convenience, toxicity and drug interaction profile compared with other regimens are to be considered before starting ART. The lack of trust between clinician and patient, active drug and alcohol use, active mental illness (e.g. depression, lack of patient education and inability of patients to identify their medications, lack of reliable access to primary medical care or medication are considered to be predictors of inadequate adherence. Interventions at various levels, viz. patient level, medication level, healthcare level and community level, boost adherence and overall outcome of ART.

    Objective In resource-limited settings without safe alternatives to breastfeeding, the WHO recommends exclusive breastfeeding and antiretroviral (ARV) prophylaxis. Given the high prevalence of anemia among HIV-infected women, mothers and their infants (via fetal iron accretion) may be at risk of iron deficiency. We assessed the effects of maternal micronutrient-fortified lipid-based nutrient supplements (LNS) and maternal ARV treatment or infant ARV prophylaxis on maternal and infant iron status during exclusive breastfeeding from birth to 24 weeks. Methods The Breastfeeding, Antiretrovirals, and Nutrition Study was a randomized controlled trial conducted in Lilongwe, Malawi from 2004-2010. HIV-infected mothers (CD4>200 cells/ul) and their infants were randomly assigned to 28-week interventions: maternal-LNS/maternal-ARV (n=424), maternal-LNS/infant-ARV (n=426), maternal-LNS (n=334), maternal-ARV (n=425), infant-ARV (n=426), or control (n=334). Longitudinal models tested intervention effects on hemoglobin (Hb). In a subsample (n=537) with multiple iron indicators, intervention effects on Hb, transferrin receptors (TfR) and ferritin were tested with linear and Poisson regression. Results In longitudinal models, LNS effects on maternal and infant Hb were minimal. In subsample mothers, maternal ARVs were associated with tissue iron depletion (TfR>8.3 mg/L) (Risk ratio (RR): 3.1, p0.1). In subsample infants, interventions were not associated with impaired iron status (all p-values>0.1). Conclusions Maternal ARV treatment with protease inhibitors is associated with maternal tissue iron depletion; but LNS mitigates adverse effects. ARVs do not appear to influence infant iron status; however, extended use needs to be evaluated. PMID:25723140

    Background Antiretroviral-based interventions for HIV-1 prevention, including antiretroviral therapy (ART) to reduce the infectiousness of HIV-1 infected persons and pre-exposure prophylaxis (PrEP) to reduce the susceptibility of HIV-1 uninfected persons, showed high efficacy for HIV-1 protection in randomized clinical trials. We conducted a prospective implementation study to understand the feasibility and effectiveness of these interventions in delivery settings. Methods and Findings Between November 5, 2012, and January 5, 2015, we enrolled and followed 1,013 heterosexual HIV-1-serodiscordant couples in Kenya and Uganda in a prospective implementation study. ART and PrEP were offered through a pragmatic strategy, with ART promoted for all couples and PrEP offered until 6 mo after ART initiation by the HIV-1 infected partner, permitting time to achieve virologic suppression. One thousand thirteen couples were enrolled, 78% of partnerships initiated ART, and 97% used PrEP, during a median follow-up of 0.9 years. Objective measures of adherence to both prevention strategies demonstrated high use (≥85%). Given the low HIV-1 incidence observed in the study, an additional analysis was added to compare observed incidence to incidence estimated under a simulated counterfactual model constructed using data from a prior prospective study of HIV-1-serodiscordant couples. Counterfactual simulations predicted 39.7 HIV-1 infections would be expected in the population at an incidence of 5.2 per 100 person-years (95% CI 3.7–6.9). However, only two incident HIV-1 infections were observed, at an incidence of 0.2 per 100 person-years (95% CI 0.0–0.9, p 5% per year. PMID:27552090

    Full Text Available Antiretroviral therapy has been associated with side effects, either from the drug itself or in conjunction with the effects of human immunodeficiency virus infection. Here, we evaluated the side effects of the protease inhibitor (PI indinavir in hamsters consuming a normal or high-fat diet. Indinavir treatment increased the hamster death rate and resulted in an increase in triglyceride, cholesterol and glucose serum levels and a reduction in anti-oxLDL auto-antibodies. The treatment led to histopathological alterations of the kidney and the heart. These results suggest that hamsters are an interesting model for the study of the side effects of antiretroviral drugs, such as PIs.

    We have treated a total of 40 patients who presented chronic pain secondary to a neoplastic condition; the patients were treated with morphine in a continuous perfusion by means of an implanted perfusion pump. The route used was the epidural route in seven patients and the intrathecal route in the remaining 33 patients. In 22 patients, the implanted pump was the continuous flow Infusaid model and in the remaining 18, the programmable flow Synchromed (Medtronic) model. The daily dose of morphine ranged from 2.4 mg to 48 mg and maximum perfusion period was 19 months. Main complications were displacement of the catheter and rejection of perfusion system. Despite its high prize, we believe that such treatment system should be considered because of the quality of life improvement of the patients. PMID:2098877

  1. Generic antiretroviral drugs and HIV care: An economic review.

    Science.gov (United States)

    Yazdanpanah, Y; Schwarzinger, M

    2016-03-01

    The cost of HIV care in European countries is high. Direct medical costs, in France, have been estimated at 500,000 Euros per patient's lifetime (20,000 Euros/year/patient). Overall, 73% of these costs are related to antiretroviral treatments. In the current financial crisis context, some European countries are beginning to make economic decisions on the drugs to be used. These approaches are likely to become more frequent. It is obviously essential to prescribe the most effective, appropriate, best tolerated, and easy-to-use antiretroviral treatments to patients. However, while taking the above into consideration, and if various treatment options or combinations are available, cost should also be considered in the treatment choice. One may thus reflect on the use of generic antiretroviral agents as they have just been launched in France. We aimed to review the cost and cost-effectiveness of generic antiretroviral drugs and to review treatment strategies other than generic drugs that could help reduce HIV-related costs. HIV clinicians should consider treatment costs to avoid any future coercive measures.

    Full Text Available Abstract In this study we report the prevalence of antiretroviral drug resistant HIV-1 genotypes of virus isolated from Djiboutian patients who failed first-line antiretroviral therapy (ART and from ART naïve patients. Patients and methods A total of 35 blood samples from 16 patients who showed first-line ART failure (>1000 viral genome copies/ml and 19 ART-naïve patients were collected in Djibouti from October 2009 to December 2009. Both the protease (PR and reverse transcriptase (RT genes were amplified and sequenced using National Agency for AIDS Research (ANRS protocols. The Stanford HIV database algorithm was used for interpretation of resistance data and genotyping. Results Among the 16 patients with first-line ART failure, nine (56.2% showed reverse transcriptase inhibitor-resistant HIV-1 strains: two (12.5% were resistant to nucleoside (NRTI, one (6.25% to non-nucleoside (NNRTI reverse transcriptase inhibitors, and six (37.5% to both. Analysis of the DNA sequencing data indicated that the most common mutations conferring drug resistance were M184V (38% for NRTI and K103N (25% for NNRTI. Only NRTI primary mutations K101Q, K103N and the PI minor mutation L10V were found in ART naïve individuals. No protease inhibitor resistant strains were detected. In our study, we found no detectable resistance in ∼ 44% of all patients who experienced therapeutic failure which was explained by low compliance, co-infection with tuberculosis and malnutrition. Genotyping revealed that 65.7% of samples were infected with subtype C, 20% with CRF02_AG, 8.5% with B, 2.9% with CRF02_AG/C and 2.9% with K/C. Conclusion The results of this first study about drug resistance mutations in first-line ART failures show the importance of performing drug resistance mutation test which guides the choice of a second-line regimen. This will improve the management of HIV-infected Djiboutian patients. Virtual slides The virtual slide(s for this article can be found

  6. Treatment technologies for low and intermediate level waste from nuclear applications. Final report of a co-ordinated research programme 1991-1996

    International Nuclear Information System (INIS)

    Low and intermediate level radioactive waste is generated from the use of radioactive materials in industrial applications, research and medicine. The waste management programmes and activities in many developing Member States have been reviewed through a Waste Management Advisory Programme (WAMAP) implemented by the IAEA in 1987-1995. One of the WAMAP objectives was to assist in practical development and implementation of safe and efficient waste treatment methods. In this context the IAEA has initiated a co-ordinated research programme on treatment technologies for institutional wastes covering the most important recurring problems in developing Member States. The programme was intended to cover the research and development required for reliable waste treatment operations, including the likely variations in institutional waste inputs using simple low cost processes. This co-ordinated research programme was initiated in 1991 and brought together 14 participants from 13 countries. The results of the studies were discussed at three research co-ordination meetings. This report summarizes the salient features and results obtained during five year investigations and provides recommendations for future work in this area. Refs, figs, tabs

  7. Increasing risk behaviour can outweigh the benefits of antiretroviral drug treatment on the HIV incidence among men-having-sex-with-men in Amsterdam

    2011-05-01

    Full Text Available Abstract Background The transmission through contacts among MSM (men who have sex with men is one of the dominating contributors to HIV prevalence in industrialized countries. In Amsterdam, the capital of the Netherlands, the MSM risk group has been traced for decades. This has motivated studies which provide detailed information about MSM's risk behavior statistically, psychologically and sociologically. Despite the era of potent antiretroviral therapy, the incidence of HIV among MSM increases. In the long term the contradictory effects of risk behavior and effective therapy are still poorly understood. Methods Using a previously presented Complex Agent Network model, we describe steady and casual partnerships to predict the HIV spreading among MSM. Behavior-related parameters and values, inferred from studies on Amsterdam MSM, are fed into the model; we validate the model using historical yearly incidence data. Subsequently, we study scenarios to assess the contradictory effects of risk behavior and effective therapy, by varying corresponding values of parameters. Finally, we conduct quantitative analysis based on the resulting incidence data. Results The simulated incidence reproduces the ACS historical incidence well and helps to predict the HIV epidemic among MSM in Amsterdam. Our results show that in the long run the positive influence of effective therapy can be outweighed by an increase in risk behavior of at least 30% for MSM. Conclusion We recommend, based on the model predictions, that lowering risk behavior is the prominent control mechanism of HIV incidence even in the presence of effective therapy.

    Full Text Available OBJECTIVES: To determine the proportion, characteristics and outcomes of patients who transfer-out from an antiretroviral therapy (ART service in a South African township. METHODS: This retrospective cohort study included all patients aged ≥15 years who enrolled between September 2002 and December 2009. Follow-up data were censored in December 2010. Kaplan-Meier survival analysis was used to describe time to transfer-out and cox proportional hazard analysis was used to determine associated risk factors. RESULTS: 4511 patients (4003 ART-naïve and 508 non-naïve at baseline received ART during the study period. Overall, 597 (13.2% transferred out. The probability of transferring out by one year of ART steadily increased from 1.4% in 2002/2004 cohort to 8.9% for the 2009 cohort. Independent risk factors for transfer-out were more recent calendar year of enrolment, younger age (≤25 years and being ART non-naïve at baseline (i.e., having previously transferred into this clinic from another facility. The proportions of patients transferred out who had a CD4 cell count 1000 copies/mL around the time of transfer, suggesting the need for careful adherence counseling and assessment of medication supplies among those planning transfer.

    2009-01-01

    Cancer survivor numbers in Ireland are increasing due to the success of modern treatments. Although most survivors have a good quality of life not all survivors return to \\'normal\\' after treatment. The HSE funded CANSURVIVOR research project has found that many survivors have difficulties and need help to recover and adjust after cancer treatment. Over a number of exploratory studies using interviews, focus groups and a survey of 262 breast, prostate, colorectal and lung cancer survivors, the researchers found that over 25% of survivors experienced significant difficulties with physical, emotional and social functioning, including symptoms such as insomnia and fatigue, while 33% experienced high levels of anxiety. Of particular concern were the findings that over 50% of survivors were overweight, 35% had reduced their physical activity levels and 13% continued to smoke after cancer, putting them at risk for further health problems. This evidence led to the development of an 8-week multi-disciplinary pilot rehabilitation programme. Significant quality of life improvements were achieved with increases in strength and fitness as well as a reduction in anxiety levels and dietary improvements. The researchers highlight the need for a structured, co-ordinated survivorship service, education of health professionals about survivorship and the provision of high quality information to survivors. This research was led by the School of Psychology at UCD in collaboration with the Physiotherapy and Nutrition departments of St. Vincent\\'s hospital.

  11. Using cost-effectiveness analyses to inform policy: the case of antiretroviral therapy in Thailand

    2006-12-01

    Full Text Available Abstract Background: Much emphasis is put on providing evidence to assist policymakers in priority setting and investment decisions. Assessing the cost-effectiveness of interventions is one technique used by policymakers in their decisions around the allocation of scarce resources. However, even where such evidence is available, other considerations may also be taken into account, and even over-ride technical evidence. Antiretroviral therapy (ART is the most effective intervention to reduce HIV-related morbidity and prolong mortality. However, treatment provision in the developing world has been hindered by the high costs of services and drugs, casting doubts on its cost-effectiveness. This paper looks at Thailand's publicly-funded antiretroviral initiative which was first introduced in 1992, and explores the extent to which cost-effectiveness evidence influenced policy. Methods: This article reviews the development of the national ART programme in Thailand between 1992 and 2004. It examines the roles of cost-effectiveness information in treatment policy decisions. Qualitative approaches including document analysis and interview of key informants were employed. Results: Two significant policy shifts have been observed in government-organised ART provision. In 1996, service-based therapy for a few was replaced by a research network to support clinical assessments of antiretroviral medication in public hospitals. This decision was taken after a domestic study illustrated the unaffordable fiscal burden and inefficient use of resources in provision of ART. The numbers of treatment recipients was maintained at 2,000 per year throughout the 1990s. It was not until 2001 that a new government pledged to extend the numbers receiving the service, as part of its commitment to universal coverage. Several elements played a role in this decision: new groups of dominant actors, drug price reductions, a pro-active civil society movement, lessons from experience

    2003-01-01

    Adherence to antiretroviral therapy is a powerful predictor of response to therapy. For optimal antiretroviral therapy response, individuals need to take more than 95% of their prescribed medication. The most widely used method for measuring adherence is self-report of the number of missed doses and this should be done at every clinic visit. There are several well-recognized predictors of poor adherence, such as illicit drug use, depression, limited knowledge or ambivalence about starting treatment. Adherence can be improved by addressing these issues or through other means such as pill boxes or electronic reminders. PMID:12752896

    Objective World Health Organization (WHO) prospective surveys of acquired HIV drug resistance (HIVDR) evaluate HIVDR emerging after the first year of antiretroviral therapy (ART) and associated factors. Methods Consecutive ART starters in 2009 were enrolled at three sentinel sites in Namibia. Genotyping was performed at start and after 12 months in patients with HIV viral load (VL) >1000 copies/mL. HIVDR outcomes were: HIVDR Prevention (VL ≤1000 copies/mL), Possible HIVDR (VL>1000 copies/mL without detectable HIVDR or loss to follow-up (LTFU) or ART stop), and HIVDR (VL>1000 copies/mL with detectable HIVDR). Adherence was assessed using medication possession ratio (MPR). Results Of 394 starters, at 12 months 80% were on first-line ART, 1% died, 4% transferred out, 1% stopped ART, <1% switched to second-line and 15% were LTFU. Among patients on first-line, 77% had VL testing. 94% achieved VL ≤1000 copies/mL. At baseline, 7% had HIVDR. After 12 months, among patients with VL testing, 5% had HIVDR. A majority of patients failing therapy had high level resistance to non-nucleoside reverse transcriptase inhibitors but none to protease inhibitors. All sites achieved WHO target of ≥70% HIVDR Prevention. Factors associated with not achieving HIVDR Prevention were: baseline resistance to non-nucleoside reverse transcriptase inhibitors (OR 3.0, p=0.023), WHO stage 3 or 4 at baseline (OR 2.0, p=0.012), and MPR<75% (OR 4.9, p=0.021). Conclusions Earlier ART initiation and removal of barriers to on-time drug pickups may help to prevent HIVDR. These data inform decisions at national and global levels on the effectiveness of first- and second-line regimens. PMID:25564107

  1. Southern African HIV Clinicians Society adult antiretroviral therapy guidelines: Update on when to initiate antiretroviral therapy

    Full Text Available The most recent version of the Southern African HIV Clinicians Society’s adult antiretroviral therapy (ART guidelines was published in December 2014. In the 27 August 2015 edition of the New England Journal of Medicine, two seminal randomised controlled trials that addressed the optimal timing of ART in HIV-infected patients with high CD4 counts were published: Strategic timing of antiretroviral therapy (START and TEMPRANO ANRS 12136 (Early antiretroviral treatment and/or early isoniazid prophylaxis against tuberculosis in HIV-infected adults. The findings of these two trials were consistent: there was significant individual clinical benefit from starting ART immediately in patients with CD4 counts higher than 500 cells/μL rather than deferring until a certain lower CD4 threshold or clinical indication was met. The findings add to prior evidence showing that ART reduces the risk of onward HIV transmission. Therefore, early ART initiation has the public health benefits of potentially reducing both HIV incidence and morbidity. Given this new and important evidence, the Society took the decision to provide a specific update on the section of the adult ART guidelines relating to when ART should be initiated.

    Full Text Available BACKGROUND: The anticipated scale-up of antiretroviral therapy (ART in high-prevalence, resource-constrained settings requires operational research to guide policy on the design of treatment programmes. Mathematical models can explore the potential impacts of various treatment strategies, including timing of treatment initiation and provision of laboratory monitoring facilities, to complement evidence from pilot programmes. METHODS AND FINDINGS: A deterministic model of HIV transmission incorporating ART and stratifying infection progression into stages was constructed. The impact of ART was evaluated for various scenarios and treatment strategies, with different levels of coverage, patient eligibility, and other parameter values. These strategies included the provision of laboratory facilities that perform CD4 counts and viral load testing, and the timing of the stage of infection at which treatment is initiated. In our analysis, unlimited ART provision initiated at late-stage infection (AIDS increased prevalence of HIV infection. The effect of additionally treating pre-AIDS patients depended on the behaviour change of treated patients. Different coverage levels for ART do not affect benefits such as life-years gained per person-year of treatment and have minimal effect on infections averted when treating AIDS patients only. Scaling up treatment of pre-AIDS patients resulted in more infections being averted per person-year of treatment, but the absolute number of infections averted remained small. As coverage increased in the models, the emergence and risk of spread of drug resistance increased. Withdrawal of failing treatment (clinical resurgence of symptoms, immunologic (CD4 count decline, or virologic failure (viral rebound increased the number of infected individuals who could benefit from ART, but effectiveness per person is compromised. Only withdrawal at a very early stage of treatment failure, soon after viral rebound, would have a

    Introduction There is a growing interest in the potential contribution the private sector can make towards increasing access to antiretroviral therapy (ART) in low- and middle-income settings. This article describes a public–private partnership that was developed to expand HIV care capacity in Yangon, Myanmar. The partnership was between private sector general practitioners (GPs) and a community-based non-governmental organization (International HIV/AIDS Alliance). Methods Retrospective analysis of 2119 patient records dating from March 2009 to April 2015 was conducted. Outcomes assessed were immunological response, loss to follow-up, all-cause mortality, and alive and retained in care. Follow-up time was calculated from the date of registration to the date of death, loss to follow-up, transfer out, or if still alive and known to be in care, until April 2015. Cox proportional hazards model was used to identify predictors of loss to follow-up and mortality. Kaplan–Meier survival analysis was used to estimate survival function of being alive and retained in care. Results The median number of patients for each of the 16 GPs was 42 (interquartile range (IQR): 25–227), and the median follow-up period was 13 months. The median patient age was 35 years (IQR: 30–41); 56.6% were men, 62 and 11.8% were in WHO Stage III and Stage IV at registration, respectively; median CD4 count at registration was 177 cells/mm3; and 90.7% were on ART in April 2015. The median CD4 count at registration increased from 122 cells/mm3 in 2009 to 194 cells/mm3 in 2014. Among patients on ART, CD4 counts increased from a median of 187 cells/mm3 at registration to 436 cells/mm3 at 36 months. The median time to initiation of ART among eligible patients was 29 days, with 93.8% of eligible patients being initiated on ART within 90 days. Overall, 3.3% patients were lost to follow-up, 4.2% transferred out to other health facilities, and 8.3% died during the follow-up period. Crude mortality rate

    Background and aim Severe adverse events (AEs) compromise the outcome of direct antiviral agent-based treatment in patients with advanced liver fibrosis due to HCV infection. HEP3002 is an ongoing multinational programme to evaluate safety and efficacy of telaprevir (TVR) plus pegylated-interferon-α (PEG-IFNα) and ribavirin (RBV) in patients with advanced liver fibrosis caused by HCV genotype 1 (HCV-1). Methods 1782 patients with HCV-1 and bridging fibrosis or compensated cirrhosis were prospectively recruited from 16 countries worldwide, and treated with 12 weeks of TVR plus PEG-IFN/RBV, followed by 12 or 36 weeks of PEG-IFN and RBV (PR) alone dependent on virological response to treatment and previous response type. Results 1587 patients completed 12 weeks of triple therapy and 4 weeks of PR tail (53% cirrhosis, 22% HCV-1a). By week 12, HCV RNA was undetectable in 85% of naives, 88% of relapsers, 80% of partial responders and 72% of null responders. Overall, 931 patients (59%) developed grade 1–4 anaemia (grade 3/4 in 31%), 630 (40%) dose reduced RBV, 332 (21%) received erythropoietin and 157 (10%) were transfused. Age and female gender were the strongest predictors of anaemia. 64 patients (4%) developed a grade 3/4 rash. Discontinuation of TVR due to AEs was necessary in 193 patients (12%). Seven patients died (0.4%, six had cirrhosis). Conclusions In compensated patients with advanced fibrosis due to HCV-1, triple therapy with TVR led to satisfactory rates of safety, tolerability and on-treatment virological response with adequate managements of AEs.

    Full Text Available BACKGROUND: Although antiretroviral therapy (ART is known to be associated with time-dependent reductions in tuberculosis (TB incidence, the long-term impact of ART on incidence remains imprecisely defined due to limited duration of follow-up and incomplete CD4 cell count recovery in existing studies. We determined TB incidence in a South African ART cohort with up to 8 years of follow-up and stratified rates according to CD4 cell count recovery. We compared these rates with those of HIV-uninfected individuals living in the same community. METHODOLOGY/PRINCIPAL FINDINGS: Prospectively collected clinical data on patients receiving ART in a community-based cohort in Cape Town were analysed. 1544 patients with a median follow-up of 5.0 years (IQR 2.4-5.8 were included in the analysis. 484 episodes of incident TB (73.6% culture-confirmed were diagnosed in 424 patients during 6506 person-years (PYs of follow-up. The TB incidence rate during the first year of ART was 12.4 (95% CI 10.8-14.4 cases/100PYs and decreased to 4.92 (95% CI 3.64-8.62 cases/100PYs between 5 and 8 years of ART. During person-time accrued within CD4 cell strata 0-100, 101-200, 201-300, 301-400, 401-500, 501-700 and ≥700 cells/µL, TB incidence rates (95% CI were 25.5 (21.6-30.3, 11.2 (9.4-13.5, 7.9 (6.4-9.7, 5.0 (3.9-6.6, 5.1 (3.8-6.8, 4.1 (3.1-5.4 and 2.7 (1.7-4.5 cases/100PYs, respectively. Overall, 75% (95% CI 70.9-78.8 of TB episodes were recurrent cases. Updated CD4 cell count and viral load measurements were independently associated with long-term TB risk. TB rates during person-time accrued in the highest CD4 cell count stratum (>700 cells/µL were 4.4-fold higher that the rate in HIV uninfected individuals living in the same community (2.7 versus 0.62 cases/100PYs; 95%CI 0.58-0.65. CONCLUSIONS/SIGNIFICANCE: TB rates during long-term ART remained substantially greater than rates in the local HIV uninfected populations regardless of duration of ART or attainment of CD4

    The use of antiretroviral therapy in HIV infected subjects prevents AIDS-related illness and delayed occurrence of death. In Panama, rollout of ART started in 1999 and national coverage has reached 62.8% since then. The objective of this study was to determine the level and patterns of acquired drug resistance mutations of clinical relevance (ADR-CRM) and surveillance drug resistance mutations (SDRMs) from 717 HIV-1 pol gene sequences obtained from 467 ARV drug-experienced and 250 ARV drug-naïve HIV-1 subtypes B infected subjects during 2007–2013, respectively. The overall prevalence of SDRM and of ADR-CRM during the study period was 9.2% and 87.6%, respectively. The majority of subjects with ADR-CRM had a pattern of mutations that confer resistance to at least two classes of ARV inhibitors. The non-nucleoside reverse transcriptase inhibitor (NNRTI) mutations K103N and P225H were more prevalent in both ARV drug-naïve and ARV drug-experienced subjects. The nucleoside reverse transcriptase inhibitor (NRTI) mutation M184V was more frequent in ARV drug-experienced individuals, while T215YFrev and M41L were more frequent in ARV drug-naïve subjects. Prevalence of mutations associated to protease inhibitors (PI) was lower than 4.1% in both types of subjects. Therefore, there is a high level of resistance (>73%) to Efavirenz/Nevirapine, Lamivudine and Azidothymidine in ARV drug-experienced subjects, and an intermediate to high level of resistance (5–10%) to Efavirenz/Nevirapine in ARV drug-naïve subjects. During the study period, we observed an increasing trend in the prevalence of ADR-CRM in subjects under first-line schemes, but not significant changes in the prevalence of SDRM. These results reinforce the paramount importance of a national surveillance system of ADR-CRM and SDRM for national management policies of subjects living with HIV. PMID:27119150

Therefore, there is a high level of resistance (>73%) to Efavirenz/Nevirapine, Lamivudine and Azidothymidine in ARV drug-experienced subjects, and an intermediate to high level of resistance (5-10%) to Efavirenz/Nevirapine in ARV drug-naïve subjects. During the study period, we observed an increasing trend in the prevalence of ADR-CRM in subjects under first-line schemes, but not significant changes in the prevalence of SDRM. These results reinforce the paramount importance of a national surveillance system of ADR-CRM and SDRM for national management policies of subjects living with HIV.

    Full Text Available The use of antiretroviral therapy in HIV infected subjects prevents AIDS-related illness and delayed occurrence of death. In Panama, rollout of ART started in 1999 and national coverage has reached 62.8% since then. The objective of this study was to determine the level and patterns of acquired drug resistance mutations of clinical relevance (ADR-CRM and surveillance drug resistance mutations (SDRMs from 717 HIV-1 pol gene sequences obtained from 467 ARV drug-experienced and 250 ARV drug-naïve HIV-1 subtypes B infected subjects during 2007-2013, respectively. The overall prevalence of SDRM and of ADR-CRM during the study period was 9.2% and 87.6%, respectively. The majority of subjects with ADR-CRM had a pattern of mutations that confer resistance to at least two classes of ARV inhibitors. The non-nucleoside reverse transcriptase inhibitor (NNRTI mutations K103N and P225H were more prevalent in both ARV drug-naïve and ARV drug-experienced subjects. The nucleoside reverse transcriptase inhibitor (NRTI mutation M184V was more frequent in ARV drug-experienced individuals, while T215YFrev and M41L were more frequent in ARV drug-naïve subjects. Prevalence of mutations associated to protease inhibitors (PI was lower than 4.1% in both types of subjects.

    Full Text Available Abstract Background Among people living with HIV (PLHIV on antiretroviral therapy (ART, it is important to determine how quality of life (QOL may be improved and HIV-related stigma can be lessened over time. This study assessed the effect of peer support on QOL and internal stigma during the first year after initiating ART among a cohort of PLHIV in north-eastern Vietnam. Methods A sub-sample study of a randomised controlled trial was implemented between October 2008 and November 2010 in Quang Ninh, Vietnam. In the intervention group, participants (n = 119 received adherence support from trained peer supporters who visited participants’ houses biweekly during the first two months, thereafter weekly. In the control group, participants (n = 109 were treated according to standard guidelines, including adherence counselling, monthly health check and drug refills. Basic demographics were measured at baseline. QOL and internal stigma were measured using a Vietnamese version of the WHOQOL-HIVBREF and Internal AIDS-related Stigma Scale instruments at baseline and 12 months. T-tests were used to detect the differences between mean values, multilevel linear regressions to determine factors influencing QOL. Results Overall, QOL improved significantly in the intervention group compared to the control group. Among participants initiating ART at clinical stages 3 and 4, education at high school level or above and having experiences of a family member dying from HIV were also associated with higher reported QOL. Among participants at clinical stage 1 and 2, there was no significant effect of peer support, whereas having children was associated with an increased QOL. Viral hepatitis was associated with a decreased QOL in both groups. Lower perceived stigma correlated significantly but weakly with improved QOL, however, there was no significant relation to peer support. Conclusion The peer support intervention improved QOL after 12 months among ART

    Full Text Available A large proportion of homeless people in the UK are former members of the armed services and suffer from a mental illness. In fact, homelessness itself can be considered a symptom or manifestation of other underlying psychological difficulties. For these reasons Community Housing and Therapy (CHT considers that providing psychological therapies to treat the homeless population is a more effective way of tackling the problem of homelessness, as it addresses the roots of the problem. This approach is one which is beginning to be recognised by leading agencies in the field. At the same time, the provision of psychological therapies for symptoms such as depression and anxiety has become accepted through the Department of Health’s (DoH Increased Access to Psychological Therapies ( IAPT initiative. Depression is the most common psychiatric disorder that homeless people suffer and it is well documented that psychological treatments for depression can be extremely effective. As well as approaching homelessness from the angle of psychological therapies, CHT in its work with the ex-service community has become increasingly aware that there are a large number of non statutory homeless that do not get the same attention as rough sleepers.

    Full Text Available Abstract Background The new Certas™ shunt for the treatment of hydrocephalus has seven standard pressure settings that according to the manufacturer range from 36 to 238 mmH2O, and an additional “Virtual Off” setting with an opening pressure >400 mmH2O. Information on actual pressure response and reliability of shunt performance is important in clinical application, especially the “Virtual Off” setting as a non-surgical replacement for shunt ligation. The objective of this study was to evaluate the in-vitro hydrodynamic performance of the Certas™ shunt. Methods Six new Certas™ shunts with proximal and distal catheters were tested with an automated, computerized test system that raised the pressure from zero to a maximum pressure and back to zero at each valve setting. Opening pressure and flow resistance were determined. Results For settings 1–7 the measured opening pressure range was 26 to 247 mmH2O, and the mean change in opening pressure for a one-step adjustment was between 33 and 38 mmH2O. For setting 8 (“Virtual Off” the measured mean opening pressure was 494 ± 34 mmH2O (range 451 to 556 mmH2O. The mean outflow resistance was 7.0 mmHg/ml/min (outflow conductance 17.9 μl/s/kPa. Conclusions The six shunts had similar characteristics and closely matched the manufacturer’s specifications for opening pressure at settings 1–7. The opening pressure for the “Virtual Off” setting was nearly 500 mmH2O, which is 100 mmH2O higher than the manufacturer’s specification of “>400” and should be functionally off for most patients with communicating hydrocephalus. Clinical studies are needed to evaluate if the CSF dynamic profile persists after implantation in patients.

  15. Lay workers in directly observed treatment (DOT) programmes for tuberculosis in high burden settings: Should they be paid? A review of behavioural perspectives.

    2002-08-01

    The current global tuberculosis (TB) epidemic has pressured health care managers, particularly in developing countries, to seek for alternative, innovative ways of delivering effective treatment to the large number of TB patients diagnosed annually. One strategy employed is direct observation of treatment (DOT) for all patients. In high-burden settings innovation with this strategy has resulted into the use of lay community members to supervise TB patients during the duration of anti-TB treatment. However, community involvement in health programmes is not a simple matter. There is often a need for continued motivation of community members in order to ensure sustainability of such projects. Lay workers may demand payment for work done particularly if this takes up a reasonable proportion of their time. TB treatment, by its very nature, lasts for a considerable period and this paper seeks to examine behavioural perspectives that attempt to address the issue of whether lay workers in such programmes should be paid for their services. The theories explored suggest intrinsic and extrinsic motivation as factors that lead people to volunteer for health programmes. Intrinsic motivation encompasses such feelings as empathy and altruism as well as other factors such as religious and cultural conviction. The authors argue however that in high-burden TB settings, these factors alone may be inadequate to provide continued motivation for lay worker involvement in health programmes. Extrinsic motivators, of which money is the strongest example, then also serve to keep sustained interest particularly in resource-limited settings where people expect payment for work done. The debate on whether lay workers in health programmes should be paid is thus compounded by issues such as what factors one believes are responsible for motivation in particular contextual settings; how long lay persons are expected to perform tasks at hand; the capacity that exists to pay them and the

  18. New antiretrovirals and new combinations.

    The appearance in the clinic of two to three new antiretroviral agents yearly since 1995 has permitted unprecedented advances in HIV treatment. This remarkable pace of drug development is a testimony to an extraordinary international effort involving scientists, clinicians, governments, community activists and industry dedicated to the rapid and safe development of novel therapies. New drugs present the opportunity to improve HIV therapy. They also create an enormous challenge to the clinician, who must constantly assimilate data on new drugs and incorporate this information into practical management strategies. Combination therapy has proven the most effective approach to treat HIV disease. The profound and sustained viral suppression achievable with combinations such as indinavir (IDV), lamivudine (3TC) and zidovudine (ZDV) have resulted in a dramatic shift in HIV treatment paradigms over the last year. The full potential of combination therapy with available drugs has yet to be realized as only a limited number of the possible combinations incorporating new drugs have been fully tested. Even drugs available for many years may have untapped potential. Didanosine (ddI) and stavudine (d4T), once thought to be contraindicated in combination because of their overlapping peripheral neuropathy toxicity, have proven well tolerated and effective. Combination therapy can increase antiviral suppression, prevent drug resistance, optimize drug exposure and simplify dosing, but it can also result in pharmacologic antagonism, subtherapeutic drug concentrations and unexpected toxicities. Clinical studies have confirmed in vitro studies showing pharmacologic antagonism for the combination of ZDV and d4T. Combining protease inhibitors with each other or with non-nucleoside reverse transcriptase inhibitors is complicated by effects both classes of drugs have on drug metabolism and clearance. These observations underline the importance of carefully conducted clinical studies to

    Full Text Available Abstract Background The scarcity of physicians in sub-Saharan Africa – particularly in rural clinics staffed only by non-physician health workers – is constraining access to HIV treatment, as only they are legally allowed to start antiretroviral therapy in the HIV-positive patient. Here we present a pilot study from Uganda assessing agreement between non-physician clinicians (nurses and clinical officers and physicians in their decisions as to whether to start therapy. Methods We conducted the study at 12 government antiretroviral therapy sites in three regions of Uganda, all of which had staff trained in delivery of antiretroviral therapy using the WHO Integrated Management of Adult and Adolescent Illness guidelines for chronic HIV care. We collected seven key variables to measure patient assessment and the decision as to whether to start antiretroviral therapy, the primary variable of interest being the Final Antiretroviral Therapy Recommendation. Patients saw either a clinical officer or nurse first, and then were screened identically by a blinded physician during the same clinic visit. We measured inter-rater agreement between the decisions of the non-physician health workers and physicians in the antiretroviral therapy assessment variables using simple and weighted Kappa analysis. Results Two hundred fifty-four patients were seen by a nurse and physician, while 267 were seen by a clinical officer and physician. The majority (> 50% in each arm of the study were in World Health Organization Clinical Stages I and II and therefore not currently eligible for antiretroviral therapy according to national antiretroviral therapy guidelines. Nurses and clinical officers both showed moderate to almost perfect agreement with physicians in their Final Antiretroviral Therapy Recommendation (unweighted κ = 0.59 and κ = 0.91, respectively. Agreement was also substantial for nurses versus physicians for assigning World Health Organization Clinical

    Full Text Available Abstract Background The main objective of this study was to assess the effectiveness of integrating the use of cell-phones into a routine malaria prevention and control programme, to improve the management of malaria cases among an under-served population in a border area. The module for disease and treatment monitoring of malaria (DTMM consisted of case investigation and case follow-up for treatment compliance and patients' symptoms. Methods The module combining web-based and mobile technologies was developed as a proof of concept, in an attempt to replace the existing manual, paper-based activities that malaria staff used in treating and caring for malaria patients in the villages for which they were responsible. After a patient was detected and registered onto the system, case-investigation and treatment details were recorded into the malaria database. A follow-up schedule was generated, and the patient's status was updated when the malaria staff conducted their routine home visits, using mobile phones loaded with the follow-up application module. The module also generated text and graph messages for a summary of malaria cases and basic statistics, and automatically fed to predetermined malaria personnel for situation analysis. Following standard public-health practices, access to the patient database was strictly limited to authorized personnel in charge of patient case management. Results The DTMM module was developed and implemented at the trial site in late November 2008, and was fully functioning in 2009. The system captured 534 malaria patients in 2009. Compared to paper-based data in 2004-2008, the mobile-phone-based case follow-up rates by malaria staff improved significantly. The follow-up rates for both Thai and migrant patients were about 94-99% on Day 7 (Plasmodium falciparum and Day 14 (Plasmodium vivax and maintained at 84-93% on Day 90. Adherence to anti-malarial drug therapy, based on self-reporting, showed high completion

    Direct-to-consumer (DTC) prescription drug advertisements for HIV anti-retrovirals are controversial and have been criticized in the past for including deceptive images and underplaying HIV drug limitations. We sought to describe the state of recent DTC ads for HIV antiretrovirals in popular magazines by performing a content analysis of all complete DTC ads for antiretroviral medications appearing in eight national magazines during a one-year period. Current ads appear to have addressed previous concerns, but important problems still exist, such as failing to specify the medication's role in current treatment, to quantify drug efficacy, or to highlight life-threatening side effects.

    Full Text Available OBJECTIVE: To assess differences in body circumferences and body mass index (BMI, kg/m(2 between antiretroviral treatment (ART naïve HIV-infected and HIV-uninfected persons. METHODS: Waist, arm, and thigh circumferences and BMI were measured within the ALLRT and NHANES cohorts between 1998 and 2007. ALLRT is a prospective, longitudinal study of U.S. participants enrolled in randomized HIV treatment studies conducted by the AIDS Clinical Trials Group (ACTG. NHANES is a representative group of the US population. The cohorts were analyzed in two time periods, to account for trends towards increased adiposity. Anthropometrics were displayed in percentiles by age and sex. Multiple linear regression models examined differences between cohorts. RESULTS: ALLRT had more males (82% versus 48%, p<0.0001, more black participants (32% versus 23%, p<0.0001, and less Hispanics (21% versus 30%, p<0.0001 than NHANES. Mean BMI was smaller in ALLRT males and females compared to NHANES by 1.6-2.4 kg/m(2 (p<0.0001. Mean waist and arm circumferences in both sexes and time periods were significantly smaller in ALLRT than in NHANES (p<0.0001. Mean thigh circumference in ALLRT was also smaller than NHANES among males (p<0.0001 in both time periods and females (p = 0.01 in the early time period. CONCLUSIONS: Differences in anthropometrics existed prior to ART initiation, in this large national cohort of HIV-infected individuals, compared to a representative HIV-uninfected cohort, indicating that HIV and its complications have important effects on body shape. Further longitudinal examination of anthropometrics in this HIV-infected cohort may provide additional insight into disease risk. TRIAL REGISTRATION: NCT00001137 at www.clinicaltrials.gov.

    Conclusions: Our findings show that males presented late for ART initiation compared to females. Similar to other studies, males had higher patient attrition and mortality compared to females and this may be attributed in part to late presentation for HIV treatment and care. These observations highlight the need to encourage early HIV testing and enrolment into HIV treatment and care, and eventually patient retention on ART, particularly amongst men.

    Full Text Available Abstract The number of people receiving antiretroviral treatment (ART has increased considerably in recent years and is expected to continue to grow in the coming years. A major challenge is to maintain uninterrupted supplies of antiretroviral (ARV drugs and prevent stock outs. This article discusses issues around the management of ARVs and prevention of stock outs in Malawi, a low-income country with a high HIV/AIDS burden, and a weak procurement and supply chain management system. This system for ARVs, paid for by the Global Fund to Fight AIDS, Tuberculosis and Malaria, and bypassing the government Central Medical Stores, is in place, using the United Nations Children’s Fund’s (UNICEF’s procurement services. The system, managed by a handful of people who spend limited time on supply management, is characterized by a centrally coordinated quantification based on verified data from all national ART clinics, parallel procurement through UNICEF, and direct distribution to ART clinics. The model worked well in the first years of the ART programme with a single first-line ARV regimen, but with more regimens becoming available (e.g., alternative first-line, second-line and paediatric regimens, it has become more difficult to administer. Managing supplies through a parallel system has the advantage that weaknesses in the national system have limited influence on the ARV procurement and supply chain management system. However, as the current system operates without a central warehouse and national buffer stock capacity, it diminishes the ability to prevent ARV stock outs. The process of ordering ARVs, from the time that estimates are made to the arrival of supplies in health facilities, takes approximately one year.

    Coadministration of antituberculosis and antiretroviral therapy is often inevitable in high-burden countries where tuberculosis (TB) is the most common opportunistic infection associated with HIV/AIDS. Concurrent use of rifampicin and many antiretroviral drugs is complicated by pharmacokinetic drug-drug interactions. Rifampicin is a very potent enzyme inducer, which can result in subtherapeutic antiretroviral drug concentrations. In addition, TB drugs and antiretroviral drugs have additive (pharmacodynamic) interactions as reflected in overlapping adverse effect profiles. This review provides an overview of the pharmacological interactions between rifampicin-based TB treatment and antiretroviral drugs in adults living in resource-limited settings. Major progress has been made to evaluate the interactions between TB drugs and antiretroviral therapy; however, burning questions remain concerning nevirapine and efavirenz effectiveness during rifampicin-based TB treatment, treatment options for TB-HIV-coinfected patients with nonnucleoside reverse transcriptase inhibitor resistance or intolerance, and exact treatment or dosing schedules for vulnerable patients including children and pregnant women. The current research priorities can be addressed by maximizing the use of already existing data, creating new data by conducting clinical trials and prospective observational studies and to engage a lobby to make currently unavailable drugs available to those most in need.

    Full Text Available Abstract Background As ART programmes in African settings expand beyond the pilot stages, adherence to treatment may become an increasing challenge. This qualitative study examines potential barriers to, and facilitators of, adherence to ART in a workplace programme in South Africa. Methods We conducted key informant interviews with 12 participants: six ART patients, five health service providers (HSPs and one human resources manager. Results The main reported barriers were denial of existence of HIV or of one's own positive status, use of traditional medicines, speaking a different language from the HSP, alcohol use, being away from home, perceived severity of side-effects, feeling better on treatment and long waiting times at the clinic. The key facilitators were social support, belief in the value of treatment, belief in the importance of one's own life to the survival of one's family, and the ability to fit ART into daily life schedules. Conclusion Given the reported uncertainty about the existence of HIV disease and the use of traditional medicines while on ART, despite a programme emphasising ART counselling, there is a need to find effective ways to support adherence to ART even if the individual does not accept biomedical concepts of HIV disease or decides to use traditional medicines. Additionally, providers should identify ways to minimize barriers in communication with patients with whom they have no common language. Finally, dissatisfaction with clinical services, due to long waiting times, should be addressed.

    Full Text Available Immune reconstitution inflammatory syndrome (IRIS in HIV-infected subjects initiating antiretroviral therapy most commonly involves new or worsening manifestations of previously subclinical or overt infectious diseases. Reports of non-infectious IRIS are much less common but represent important diagnostic and treatment challenges. We report on a 34-year-old HIV-infected male patient with no history of gout who developed acute gouty arthritis in a single joint one month after initiating highly active antiretroviral therapy.

    Full Text Available Introduction: Adherence to antiretroviral therapy (ART plays an important role in treatment outcomes. It is crucial to identify factors influencing adherence in order to optimize treatment responses. The aim of this study was to assess the rates of, and factors associated with, suboptimal adherence (SubAdh in the first 24 months of ART in an Asian HIV cohort. Methods: As part of a prospective resistance monitoring study, the TREAT Asia Studies to Evaluate Resistance Monitoring Study (TASER-M collected patients’ adherence based on the World Health Organization-validated Adherence Visual Analogue Scale. SubAdh was defined in two ways: (i 14 days. Time was divided into four intervals: 0–6, 6–12, 12–18 and 18–24 months. Factors associated with SubAdh were analysed using generalized estimating equations. Results: Out of 1316 patients, 32% ever reported 2 assessments per patient per year had an odds ratio (OR=0.7 (95% confidence interval (CI (0.55 to 0.90, p=0.006, compared to sites with ≤2 assessments per patient per year. Compared to heterosexual exposure, SubAdh was higher in injecting drug users (IDUs (OR=1.92, 95% CI (1.23 to 3.00, p=0.004 and lower in homosexual exposure (OR=0.52, 95% CI (0.38 to 0.71, p<0.001. Patients taking a nucleoside transcriptase inhibitor and protease inhibitor (NRTI+PI combination were less likely to report adherence <100% (OR=0.36, 95% CI (0.20 to 0.67, p=0.001 compared to patients taking an NRTI and non-nucleoside transcriptase inhibitor (NRTI+NNRTI combination. SubAdh decreased with increasing time on ART (all p<0.001. Similar associations were found with adherence <95% as the outcome. Conclusions: We found that SubAdh, defined as either <100% and <95%, was associated with mode of HIV exposure, ART regimen, time on ART and frequency of adherence measurement. The more frequently sites assessed patients, the lower the SubAdh, possibly reflecting site resourcing for patient counselling. Although social

    Full Text Available BACKGROUND: There is paucity of data from India on the impact of HIV related immunosuppression in response to TB treatment and mortality among HIV infected TB patients. We assessed the TB treatment outcome and mortality in a cohort of HIV infected TB patients treated with intermittent short course chemotherapy under TB control programme in a high HIV prevalent district of south India. METHODOLOGY/ FINDINGS: Among 3798 TB patients registered for treatment in Mysore district from July 2007 to June 2008, 281 HIV infected patients formed the study group. The socio-demographic and treatment related data of these patients was obtained from TB and HIV programme records and patient interviews 19 months after TB treatment initiation by field investigators. Treatment success rate of 281 patients was 75% while in smear positive pulmonary tuberculosis cases it was 62%, attributable to defaults (16% and deaths (19%. Only 2 patients had treatment failure. Overall, 83 (30% patients were reported dead; 26 while on treatment and 57 after TB treatment. Association of treatment related factors with treatment outcome and survival status was studied through logistic regression analysis. Factors significantly associated with 'unfavourable outcome' were disease classification as Pulmonary [aOR-1.96, CI (1.02-3.77], type of patient as retreatment [aOR-4.78, CI (2.12-10.76], and non initiation of ART [aOR-4.90, CI (1.85-12.96]. Factors associated with 'Death' were non initiation of ART [aOR-2.80, CI (1.15-6.81] and CPT [aOR-3.46, CI (1.47-8.14]. CONCLUSION: Despite the treatment success of 75% the high mortality (30% in the study group is a matter of concern and needs immediate intervention. Non initiation of ART has emerged as a high risk factor for unfavourable treatment outcome and mortality. These findings underscore the importance of expanding and improving delivery of ART services as a priority and reconsideration of the programme guidelines for ART initiation in

    More than 50 % of women living with HIV in low- and middle-income countries are of reproductive age, but there are limitations to the administration of oral contraception for HIV-infected women receiving antiretroviral therapy due to drug-drug interactions caused by metabolism via the cytochrome P450 isoenzymes and glucuronidation. However, with the development of newer antiretrovirals that use alternative metabolic pathways, options for contraception in HIV-positive women are increasing. This paper aims to review the literature on the pharmacokinetics and pharmacodynamics of oral hormonal contraceptives when given with antiretroviral agents, including those currently used in developed countries, older ones that might still be used in salvage regimens, or those used in resource-limited settings, as well as newer drugs. Nucleos(t)ide reverse transcriptase inhibitors (NRTIs), the usual backbone to most combined antiretroviral treatments (cARTs) are characterised by a low potential for drug-drug interactions with oral contraceptives. On the other hand non-NRTIs (NNRTIs) and protease inhibitors (PIs) may interact with oral contraceptives. Of the NNRTIs, efavirenz and nevirapine have been demonstrated to cause drug-drug interactions; however, etravirine and rilpivirine appear safe to use without dose adjustment. PIs boosted with ritonavir are not recommended to be used with oral contraceptives, with the exception of boosted atazanavir which should be used with doses of at least 35 µg of estrogen. Maraviroc, an entry inhibitor, is safe for co-administration with oral contraceptives, as are the integrase inhibitors (INIs) raltegravir and dolutegravir. However, the INI elvitegravir, which is given in combination with cobicistat, requires a dose of estrogen of at least 30 µg. Despite the growing evidence in this field, data are still lacking in terms of large cohort studies, randomised trials and correlations to real clinical outcomes, such as pregnancy rates, in women

  18. Evaluation of cooling water treatment programme at RAPS-3 and 4 with reference to chlorination and microbial control

    International Nuclear Information System (INIS)

    Water from Rana Pratap Sagar Lake is used in Rajasthan Atomic Power Station (RAPS) units 3 and 4 for cooling the condenser system. As the lake water is rich in nutrients and microflora, investigations were carried out on the nutrient quality, microflora distribution and chlorine decay to evaluate the cooling water treatment programme. Algal growth in emergency storage makeup water pools, weed growth on the cooling tower decks and biofilm growth on various materials (carbon steel, stainless steel, admiralty brass and cupronickel) were studied with an objective to understand the reasons for corrosion and failure of fire water pipeline. Visual examination showed that the emergency makeup water pools were infested with green algae and cyano-bacterial mats. Some algal growth was observed on induced draft cooling tower-3 structures. The bacterial counts in various water samples were low, except in emergency makeup water pool. Sulphate reducing bacteria (SRB) were present in makeup and demineralised waters. Chlorophyll pigment analysis showed that the makeup and emergency storage water pool had abundant algal growth. To prevent biofouling, chlorine is dosed at the rate of 7 kg/hr for 10 minutes; free residual oxidant (FRO) and chlorine decay were monitored at regular intervals. After 24 hrs, biofilm thickness on different materials ranged from 27-45 μm. However, the thickness was reduced by 50 % after exposure to 2 ppm of chlorine for 15 minutes. In further investigations, it was found that the anion resin beads of demineraliser plant were infested with filamentous microbes. Hence, It is recommended to treat the feed water of DM plant. Tubercles were observed inside the failed fire water carbon steel pipeline and on removing the tubercles concentric ring patterns, typical signatures of SRB corrosion were observed. For controlling the biofouling problem in the cooling water system, it is recommended to maintain a chlorine dose of 2.3 ppm (which gives 0.8 ppm FRO) for two

    China has recognized the threat of HIV to its population and responded with a national antiretroviral treatment (ART)program. However, high ART failure rates and the spread of resistance within populations are important realities to consider when developing and managing ART programs in China and worldwide. Concepts which will define treatment success and local and national programmatic goals are 1) access to ART, 2) durability of ART at the patient level, 3)scalability of treatment modalities, and the 4) sustainability of the program at the community or national level. In the face of limited resources, China must also consider when to start ARV therapy, which agents to use, when to switch them, and how to treat highly experienced patients with drug resistance. The optimal ARV regimen to start with is changing frequently with the introduction of new agents and the presentation of new data. Currently, a regimen including tenofovir, emtricitabine or lamivudine and a nonnucleoside reverse transcriptase inhibitor appears to have optimal characteristics to treat HIV/AIDS in China. However, critical to all of these choices is the evaluation of programs implemented to insure wide scale success. China has wisely begun this process of evaluating the performance of local programs through systematic monitoring and evaluation of treatment outcomes. This will allow regimens and programs that work to be expanded, and programs with high failure rates to be eliminated. In the end,evidence based data supporting treatment strategies will allow China to successfully confront its AIDS epidemic early and prevent its tragic consequences

Summary Transitioning from individual drugs to an FDC tablet needs to be managed carefully, particularly regarding stock management, ordering processes, supply-chain integrity and comprehensive patient counselling. Priority groups • Initially, FDC supply will be insufficient to provide for all FDC-suitable patients • Therefore, the National Department of Health (NDoH has recommended that the following patient groups be prioritized for FDC initiation/switch: • Priority group 1: All HIV-positive patients newly initiating ART – adults, adolescents and pregnant women (regardless of CD4 count (amendment to the guidelines for the prevention of mother-to-child transmission of HIV (PMTCT anticipated in April 2013 – and who do not have contra-indications to the FDC component drugs • Priority group 2: HIV-positive pregnant women and breastfeeding mothers currently stable on lamivudine (3TC, TDF and EFV • Priority group 3: Virologically suppressed patients on a stavudine (d4T-based regimen and who have normal renal function • Priority group 4: Stable patients receiving individual TDF, 3TC and EFV and who have tuberculosis (TB co-infection • Priority group 5: Stable patients receiving individual TDF, 3TC and EFV and who have other co-morbidites (e.g. hypertension, diabetes • Priority group 6: Patients receiving individual TDF, 3TC and EFV and who request to switch to the FDC treatment • Priority group 7: Patients receiving individual TDF, 3TC and EFV and who, after counselling, agree to switch to the FDC treatment. Important: Clinic staff must co-ordinate this process and only switch as many patients to the FDC tablet as stock allows. This should avoid patients being switched back and forth

    Lamivudine and efavirenz are among the most worldwide used drugs for acquired immune deficiency syndrome (AIDS) treatment. Solid state nuclear magnetic resonance (ssNMR), Fourier-transformed infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and thermo-optical analysis (TOA) were used to study possible interactions between these drugs, aiming the development of a fixed-dose drug combination. DSC and TOA have evidenced significant shifts on the melting points of both drugs in the mixture, which may be due to interaction between them. Although DSC and TOA results indicated incompatibility between the drugs, FTIR spectra were mostly unmodified due to overlapping peaks. The ssNMR analyses showed significant changes in chemical shifts values of the mixture when compared with spectra of pure drugs, especially in the signals relating to the deficient electron carbon atoms of both drugs. These results confirm the interactions suggested by DSC and TOA, which is probably due to acid-base interactions between electronegative and deficient electron atoms of both lamivudine and efavirenz.

    @@ China's rapidly evolving HIV/AIDS epidemic calls for a dramatic expansion of both prevention and treatment services.1,2 Official state media recently reported that for the first time, in 2008, HIV/AIDS became China's leading cause of death among infectious diseases.3 Estimates from the Ministry of Health indicate that around 700 000 people were living with HIV and 85 000 people had AIDS in 2007.4 Initially, HIV-1 infection was confined primarily to certain high-risk populations such as injection drug users (IDU) along drug-trafficking routes, and former plasma donors (FPD) in rural communities in east-central China.1,5-7 Now, however,HIV prevalence is increasing among female sex workers (FSW) and men who have sex with men (MSM).4,8 It is estimated that in 2008, approximately 45% of new HIV cases in China were attributed to heterosexual transmission and 12% to MSM; the proportion of women infected has also doubled in the past decade.

We summarized the characteristics of HIV infection and the problems existed in antiretroviral therapy for HIV. The background about the role of TCM in the prevention and treatment of HIV/AIDS was analyzed. At present, though great progress has been made in antiretroviral therapy using Western medicine for HIV infection, many problems in antiretroviral treatment remain. TCM should size up the situation, and take full advantage of its features, and actively participate in the prevention and treatment of HIV/AIDS work. In our opinion, the disadvantages of Western medicine and the characteristics and accurate positioning of TCM should be understood in the treatment and prevention of HIV with TCM so as to better play its strengths.

CONCLUSIONS: To reduce early mortality, special attention is required to ensure timely access to ART services, particularly for patients at higher risk. Patients at risk for LTFU after ART initiation should be targeted through enhancing treatment counselling and improving patient tracing system at ART clinics.

    The advent of combination antiretroviral drug regimens has transformed HIV infection from a fatal illness into a manageable chronic condition. All patients with HIV infection should be considered for antiretroviral therapy, regardless of CD4 count or HIV viral load, for individual benefit and to prevent HIV transmission. Antiretroviral drugs affect HIV in several ways: entry inhibitors block HIV entry into CD4 T cells; nucleotide and nucleoside reverse transcriptase inhibitors prevent reverse transcription from RNA to DNA via chain-terminating proteins; nonnucleoside reverse transcriptase inhibitors prevent reverse transcription through enzymatic inhibition; integrase strand transfer inhibitors block integration of viral DNA into cellular DNA; protease inhibitors block maturation and production of the virus. Current guidelines recommend six combination regimens for initial therapy. Five are based on tenofovir and emtricitabine; the other uses abacavir and lamivudine. Five include integrase strand transfer inhibitors. HIV specialists should assist with treating patients with complicated HIV infection, including patients with treatment-resistant HIV infection, coinfection with hepatitis B or C virus, pregnancy, childhood infections, severe opportunistic infections, complex drug interactions, significant drug toxicity, or comorbidities. Family physicians can treat most patients with HIV infection effectively by choosing appropriate treatment regimens, monitoring patients closely, and retaining patients in care. PMID:27092564

    Although crucial for efficacy of pharmacotherapy, adherence to prescribed medication regimens for both antiretrovirals and antidepressants is often suboptimal. As many depressed HIV-infected individuals are prescribed both antiretrovirals and antidepressants, it is important to know whether correlates of nonadherence are similar or different across type of regimen. The HIV Translating Initiatives for Depression into Effective Solutions (HI-TIDES) study was a single-blinded, longitudinal, randomized controlled effectiveness trial comparing collaborative care to usual depression care at three Veterans Affairs HIV clinics. The current investigation utilized self-report baseline interview and chart-abstracted data. Participants were 225 depressed HIV-infected patients who were prescribed an antidepressant (n=146), an antiretroviral (n=192), or both (n=113). Treatment adherence over the last 4 days was dichotomized as "less than 90% adherence" or "90% or greater adherence." After identifying potential correlates of nonadherence, we used a seemingly unrelated regression (SUR) bivariate probit model, in which the probability of adherence to HIV medications and the probability of adherence to antidepressant medications are modeled jointly. Results indicated that 75.5% (n=146) of those prescribed antiretrovirals reported 90%-plus adherence to their antiretroviral prescription and 76.7% (n=112) of those prescribed antidepressants reported 90%-plus adherence to their antidepressant prescription, while 67% of those prescribed both (n=113) reported more than 90% adherence to both regimens. SUR results indicated that education, age, and HIV symptom severity were significant correlates of antiretroviral medication adherence while gender and generalized anxiety disorder diagnosis were significant correlates of adherence to antidepressant medications. In addition, antiretroviral adherence did not predict antidepressant adherence (β=1.62, p=0.17), however, antidepressant adherence

    Objective To investigate the situation of drug resistance among HIV-infected patients receiving long term first-line combination antiretroviral treatment (cART) and to assess the interrelated risk factors. Methods A prospective cohort study was established in 8 provinces in China since 2007. Baseline information was collected in a cross-sectional survey through multi-stage random sampling. Totall of 688 HIV-infected patients who had received first-line cART and achieved virologic suppression in 2009 were enrolled into the cohort. HIV-infected patients with viral load higher than 1000 copies/ml in 2010 were detected by ViroSeqM HIV-1 genotyping system. Life table analysis was applied to calculate the incidence of drug resistance. A sensitivity analysis was applied to evaluate the effect of second-line regimens. Based on the bivariable results, the risk factors were included into the Multivariable Logistic Regression model. Results Total of 688 HIV-infected patients receiving cART and achieving virologic suppression were eligible to this study. Among those cases, 10 cases died and 8 cases switched to second-line regimens after 12 months of follow-up. There were 29 cases with a viral load higher than 1000 copies/ml among whom, 22 patients were resistant to at least one antiretroviral drug based on genotypic assay. The incidence among drug resistance was (3.4-4.6)/100 person-years. All 22 patients were resistant to non-nucleoside reverse transcriptase inhibitor (NNRT1) and 16 patients were resistant to nucleoside reverse transcriptase inhibitor (NRTIs). No case was resistant to protease inhibitor (PI) or the combination of 3TC and TDF. Compared with patients who received cART in county level clinics or above and treated successfully, those who received cART in the village level clinic (95%CI: 2.1-19.6) and experienced virologic treatment failure (95%CI: 2.2-13.0) were most likely to occur drug resistance. Conclusions The incidence of drug resistance remained low among

    Full Text Available South Africa bears the greatest burden of HIV infection globally with the most infected people living in KwaZulu-Natal (KZN. Decentralised medical care for HIV positive patients and antiretroviral therapy (ART delivery to primary health care facilities were proposed nationally to achieve adequate ART coverage for patients in need of treatment. This study described the HIV positive patients who accessed medical care and were initiated on ART at two existing government Primary Health Care (PHC clinics with no added donor support, in Ilembe, KZN. This was an observational descriptive study of ART initiation from 01 April 2008 to 30 April 2009. Data were collected from clinical records kept on site. HIV Testing and the pre-ART programmes which consisted of medical care prior to ART initiation are briefly described. Socio-economic, demographic and clinical characteristics of patients who were initiated on ART were sampled and described. A minority (2.95% of the study population tested for HIV of which 36.0%tested positive. Majority (60.0% of patients who joined the pre-ART programme care did not return. The ART sample consisted of 375 patients of whom 65.0%were women, 85.9%were unmarried, 61.6%were unemployed and 50.4%had a secondary level of education. Tuberculosis (TB prevalence and incidence at ART initiation were 22.1%and 14.7%respectively. The prevalence of Syphilis and Hepatitis B co-infections were 13.1%and 8.6 %respectively. Two thirds of female patients (66.4% received a Pap smear result of which the majority (62.3% were abnormal. Uptake for HIV testing followed by relevant CD4 testing was poor. High TB, Hepatitis B and Syphilis co-infection was noted amongst patients initiated on ART. Cervical cancer screening must be intensified. Although ART initiation with no added external resources was successful, record keeping was suboptimal.

    Objective In Brazil, universal provision of antiretroviral therapy (ART) has been guaranteed free of charge to eligible HIV-positive patients since December 1996. We sought to quantify the survival benefits of ART attributable to this programme. Methods We used a previously published microsimulation model of HIV disease and treatment (CEPAC-International) and data from Brazil to estimate life expectancy increase for HIV-positive patients initiating ART in Brazil. We divided the period of 1997 to 2014 into six eras reflecting increased drug regimen efficacy, regimen availability and era-specific mean CD4 count at ART initiation. Patients were simulated first without ART and then with ART. The 2014-censored and lifetime survival benefits attributable to ART in each era were calculated as the product of the number of patients initiating ART in a given era and the increase in life expectancy attributable to ART in that era. Results In total, we estimated that 598,741 individuals initiated ART. Projected life expectancy increased from 2.7, 3.3, 4.1, 4.9, 5.5 and 7.1 years without ART to 11.0, 17.5, 20.7, 23.0, 25.3, and 27.0 years with ART in Eras 1 through 6, respectively. Of the total projected lifetime survival benefit of 9.3 million life-years, 16% (or 1.5 million life-years) has been realized as of December 2014. Conclusions Provision of ART through a national programme has led to dramatic survival benefits in Brazil, the majority of which are still to be realized. Improvements in initial and subsequent ART regimens and higher CD4 counts at ART initiation have contributed to these increasing benefits. PMID:27029828

  16. Masculine attitudes of superiority deter men from accessing antiretroviral therapy in Dar es Salaam, Tanzania

    2013-10-01

    Full Text Available Background: This article presents part of the findings from a larger study that sought to assess the role that gender relations play in influencing equity regarding access and adherence to antiretroviral therapy (ART. Review of the literature has indicated that, in Southern and Eastern Africa, fewer men than women have been accessing ART, and the former start using ART late, after HIV has already been allowed to advance. The main causes for this gender gap have not yet been fully explained. Objective: To explore how masculinity norms limit men's access to ART in Dar es Salaam. Design: This article is based on a qualitative study that involved the use of focus group discussions (FGDs. The study employed a stratified purposive sampling technique to recruit respondents. The study also employed a thematic analysis approach. Results: Overall, the study's findings revealed that men's hesitation to visit the care and treatment clinics signifies the superiority norm of masculinity that requires men to avoid displaying weakness. Since men are the heads of families and have higher social status, they reported feeling embarrassed at having to visit the care and treatment clinics. Specifically, male respondents indicated that going to a care and treatment clinic may raise suspicion about their status of living with HIV, which in turn may compromise their leadership position and cause family instability. Because of this tendency towards ‘hiding’, the few men who register at the public care and treatment clinics do so late, when HIV-related signs and symptoms are already far advanced. Conclusion: This study suggests that the superiority norm of masculinity affects men's access to ART. Societal expectations of a ‘real man’ to be fearless, resilient, and emotionally stable are in direct conflict with expectations of the treatment programme that one has to demonstrate health-promoting behaviour, such as promptness in attending the care and treatment

    A programmable oscillator is a frequency synthesizer with an output phase that tracks an arbitrary function. An offset, phase-locked loop circuit is used in combination with an error control feedback loop to precisely control the output phase of the oscillator. To down-convert the received signal, several stages of mixing may be employed with the compensation for the time-base distortion of the carrier occurring at any one of those stages. In the Goldstone Solar System Radar (GSSR), the compensation occurs in the mixing from an intermediate frequency (IF), whose value is dependent on the station and band, to a common IF used in the final stage of down-conversion to baseband. The programmable oscillator (PO) is used in the final stage of down-conversion to generate the IF, along with a time-varying phase component that matches the time-base distortion of the carrier, thus removing it from the final down-converted signal.

    International Nuclear Information System (INIS)

    The project dealing with the incorporation of spent ion-exchange resins into bitumen was performed within the Agency coordinated research programme on treatment of spent ion-exchange resins. Physical and chemical properties of commercial ion-exchange resins, bitumens and bituminized resins were studied. It was shown that bitumen with low oil content and with a softening point of 60-70 deg. C are applicable for the incorporation of resins. The final waste form is allowed to contain maximum 50% resin. The comprehensive study of the biological resistance of B-30 bitumen was performed. That showed that any bacteriological attack can be regarded as generally insignificant. A continuously operating technology was realized on a semi-plant scale. The best operating conditions of this technology were determined. On the basis of the experience gained from the experiments a design of the bituminization plant of 50m3 dry resin/year treatment capacity was proposed

    The technology activities carried out by the Euratom-ENEA Association in the framework of the European Fusion Development Agreement concern the Next Step (International Thermonuclear Experimental Reactor - ITER), the Long-Term Programme (breeder blanket, materials, International Fusion Materials Irradiation Facility - IFMIF), Power Plant Conceptual Studies and Socio-Economic Studies. The Underlying Technology Programme was set up to complement the fusion activities as well to develop technologies with a wider range of interest. The Technology Programme mainly involves staff from the Frascati laboratories of the Fusion Technical and Scientific Unit and from the Brasimone laboratories of the Advanced Physics Technologies Unit. Other ENEA units also provide valuable contributions to the programme. ENEA is heavily engaged in component development/testing and in design and safety activities for the European Fusion Technology Programme. Although the work documented in the following covers a large range of topics that differ considerably because they concern the development of extremely complex systems, the high level of integration and coordination ensures the capability to cover the fusion system as a whole. In 2004 the most significant testing activities concerned the ITER primary beryllium-coated first wall. In the field of high-heat-flux components, an important achievement was the qualification of the process for depositing a copper liner on carbon fibre composite (CFC) hollow tiles. This new process, pre-brazed casting (PBC), allows the hot radial pressing (HRP) joining procedure to be used also for CFC-based armour monoblock divertor components. The PBC and HRP processes are candidates for the construction of the ITER divertor. In the materials field an important milestone was the commissioning of a new facility for chemical vapour infiltration/deposition, used for optimising silicon carbide composite (SiCf/SiC) components. Eight patents were deposited during 2004

    Full Text Available INTRODUCTION: To combat the AIDS epidemic and increase HIV treatment access, the South African government implemented a nurse-based, doctor-supported model of care that decentralizes administration of antiretroviral treatment (ART for HIV positive patients through nurse initiated and managed ART. Médecins Sans Frontières (MSF implemented a mentorship programme to ensure successful task-shifting, subsequently assessing the quality of clinical care provided by nurses. METHODS: A before-after cross-sectional study was conducted on nurses completing the mentorship programme in Khayelitsha, South Africa, from February 2011-September 2012. Routine clinical data from 229 patient folders and 21 self-assessment questionnaires was collected to determine the number of patients initiated on ART by nurses; quality of ART management before-after mentorship; patient characteristics for doctor and nurse ART initiations; and nurse self-assessments after mentorship. RESULTS: Twenty one nurses were authorized by one nurse mentor with one part-time medical officer's support, resulting in nurses initiating 77% of ART eligible patients. Improvements in ART management were found for drawing required bloods (91% vs 99%, p = 0.03, assessing adherence (50% vs 78%, p<0.001 and WHO staging (63% vs 91%, p<0.001. Nurse ART initiation indicators were successfully completed at 95-100% for 11 of 16 indicators: clinical presentation; patient weight; baseline blood work (CD4, creatinine, haemoglobin; STI screening; WHO stage, correlating medical history; medications prescribed appropriately; ART start date; and documented return date. Doctors initiated more patients with TB/HIV co-infection and WHO Stage 3 and 4 disease than nurses. Nurse confidence improved for managing HIV-infected children and pregnant women, blood result interpretation and long-term side effects. CONCLUSIONS: Implementation of a clinical mentorship programme in Khayelitsha led to nurse initiation of a

    @@ Antiretroviral therapy is a key determinant in the treatment and prevention of human immunodeficiency virus (HIV) infection. Initial treatment for patients with HIV infection generally includes two nucleoside reverse transcriptase inhibitors (NRTI) and a protease inhibitor (PI) or a nonnucleoside reverse transcriptase inhibitor (NNRTI). The combination antiretroviral therapy (refers to highly active antiretroviral therapy or HAART) showed a significant effect upon reducing morbidity and mortality of HIV disease. Cao and colleagues1 began the clinical application of HAART in 1999 and completed the first clinical trial in China using a combination of two NRTIs and one PI. The result in using combivir (AZT+3TC) and indinavir (2 NRTIs+1 PI) are consistent with those reported in the literature.2 In this study, we report the first virological and immunological outcomes in HIV infected Chinese patients treated with a combination of didanosine, stavudine and nevirapine (2 NRTIs+1 NNRTI) for 52 weeks.

    It is widely recognized that adherence to antiretroviral therapy is critical to long-term treatment success, yet rates of adherence to antiretroviral medications are frequently subtherapeutic. Beliefs about antiretroviral therapy and psychosocial characteristics of HIV-positive persons naive to therapy may influence early experience with antiretroviral medication adherence and therefore could be important when designing programs to improve adherence to antiretroviral therapy. As part of a multicenter AIDS Clinical Trial Group (ACTG 384) study, 980 antiretroviral-naive subjects (82% male, 47% White, median age 36 years, and median CD4 cell count 278 cells/mm3) completed a self-administered questionnaire prior to random treatment assignment of initial antiretroviral medications. Measures of symptom distress, general health and well-being, and personal and situational factors including demographic characteristics, social support, self-efficacy, depression, stress, and current adherence to (nonantiretroviral) medications were recorded. Associations among variables were explored using correlation and regression analyses. Beliefs about the importance of antiretroviral adherence and ability to take antiretroviral medications as directed (adherence self-efficacy) were generally positive. Fifty-six percent of the participants were "extremely sure" of their ability to take all medications as directed and 48% were "extremely sure" that antiretroviral nonadherence would cause resistance, but only 37% were as sure that antiretroviral therapy would benefit their health. Less-positive beliefs about antiretroviral therapy adherence were associated with greater stress, depression, and symptom distress. More-positive beliefs about antiretroviral therapy adherence were associated with better scores on health perception, functional health, social-emotional-cognitive function, social support, role function, younger age, and higher education (r values = 0.09-0.24, all p < .001).

    Procurement, the country-level process of ordering antiretrovirals (ARVs), and supply chain management, the mechanism by which they are delivered to health-care facilities, are critical processes required to move ARVs from manufacturers to patients. To provide a glimpse into the ARV procurement and supply chain, the following pages provide an overview of the primary stakeholders, principal operating models, and policies and regulations involved in ARV procurement. Also presented are key challenges that need to be addressed to ensure that the supply chain is not a barrier to the goal of universal coverage. This article will cover the steps necessary to order and distribute ARVs, including different models of delivery, key stakeholders involved, strategic considerations that vary depending on context and policies affecting them. The single drug examples given illustrate the complications inherent in fragmented supply and demand-driven models of procurement and supply chain management, and suggest tools for navigating these hurdles that will ultimately result in more secure and reliable ARV provision. Understanding the dynamics of ARV supply chain is important for the global health community, both to ensure full and efficient treatment of persons living with HIV as well as to inform the supply chain decisions for other public health products.

To provide a glimpse into the ARV procurement and supply chain, the following pages provide an overview of the primary stakeholders, principal operating models, and policies and regulations involved in ARV procurement. Also presented are key challenges that need to be addressed to ensure that the supply chain is not a barrier to the goal of universal coverage. This article will cover the steps necessary to order and distribute ARVs, including different models of delivery, key stakeholders involved, strategic considerations that vary depending on context and policies affecting them. The single drug examples given illustrate the complications inherent in fragmented supply and demand-driven models of procurement and supply chain management, and suggest tools for navigating these hurdles that will ultimately result in more secure and reliable ARV provision. Understanding the dynamics of ARV supply chain is important for the global health community, both to ensure full and efficient treatment of persons living with HIV as well as to inform the supply chain decisions for other public health products.

    Full Text Available OBJECTIVES: In developing nations, the use of operational parameters (OPs in the prediction of clinical care represents a missed opportunity to enhance the care process. We modeled the impact of multiple measurements of antiretroviral treatment (ART adherence on antiretroviral treatment outcomes in Peru. DESIGN AND METHODS: Retrospective cohort study including ART naïve, non-pregnant, adults initiating therapy at Hospital Nacional Cayetano Heredia, Lima-Peru (2006-2010. Three OPs were defined: 1 Medication possession ratio (MPR: days with antiretrovirals dispensed/days on first-line therapy; 2 Laboratory monitory constancy (LMC: proportion of 6 months intervals with ≥1 viral load or CD4 reported; 3 Clinic visit constancy (CVC: proportion of 6 months intervals with ≥1 clinic visit. Three multi-variable Cox proportional hazard (PH models (one per OP were fit for (1 time of first-line ART persistence and (2 time to second-line virologic failure. All models were adjusted for socio-demographic, clinical and laboratory variables. RESULTS: 856 patients were included in first-line persistence analyses, median age was 35.6 years [29.4-42.9] and most were male (624; 73%. In multivariable PH models, MPR (per 10% increase HR=0.66; 95%CI=0.61-0.71 and LMC (per 10% increase 0.83; 0.71-0.96 were associated with prolonged time on first-line therapies. Among 79 individuals included in time to second-line virologic failure analyses, MPR was the only OP independently associated with prolonged time to second-line virologic failure (per 10% increase 0.88; 0.77-0.99. CONCLUSIONS: The capture and utilization of program level parameters such as MPR can provide valuable insight into patient-level treatment outcomes.

    Objective: assess the adherence levels to antiretroviral therapy in people coinfected with HIV/tuberculosis and correlate these levels with the sociodemographic and clinical variables of the study population. Method: cross-sectional study involving 74 male and female adults coinfected with HIV/tuberculosis. For the data collection, a sociodemographic and clinical assessment form and the Antiretroviral Treatment Adherence Assessment Questionnaire were used. For the data analysis, the software STATA version 11 was used, through descriptive statistics, Fisher's chi-square exact test and the probability test. Results: men were predominant (79.7%), between 30 and 39 years of age (35.1%), low income (75.7%) and pulmonary tuberculosis (71.6%). Adherence to antiretroviral therapy was inappropriate in 78.1% of the men; 61.0% of single people; 47.0% unemployed and 76.5% among people gaining less than one minimum wage. A significant difference was observed between compliance and length of use of antiretrovirals (p=0.018), sexual orientation (p=0.024) and number of children (p=0.029). Conclusion: the coinfected patients presented inappropriate adherence to the antiretrovirals, a fact that negatively affects the health conditions of the people living with HIV/tuberculosis coinfection. A statistically significant correlation was found between the levels of adherence and some sociodemographic and clinical characteristics. PMID:27192416

  8. A Statistical Programme Assignment Model

    Rosholm, Michael; Staghøj, Jonas; Svarer, Michael

    When treatment effects of active labour market programmes are heterogeneous in an observable way  across the population, the allocation of the unemployed into different programmes becomes a particularly  important issue. In this paper, we present a statistical model designed to improve the present...... duration of unemployment spells may result if a statistical programme assignment model is introduced. We discuss several issues regarding the  plementation of such a system, especially the interplay between the statistical model and  case workers....

    The experiments aim at a broad exploration of the properties of atomic nuclei far away from the region of beta stability. Furthermore, the unique radioactive beams of over 60~elements produced at the on-line isotope separators ISOLDE-2 and ISOLDE-3 are used in a wide programme of atomic, solid state and surface physics. Around 300 scientists are involved in the project, coming from about 70 laboratories. \\\\ \\\\ The electromagnetic isotope separators are connected on-line with their production targets in the extracted 600 MeV proton or 910~MeV Helium-3 beam of the Synchro-Cyclotron. Secondary beams of radioactive isotopes are available at the facility in intensities of 10$^1

    The authors assessed CSF and plasma HIV-1 RNA and neuropsychological test performance (composite neuropsychological test Z score [NPZ-4]) in 25 HIV-1–infected subjects 4 and 8 weeks after beginning potent antiretroviral therapy that included a protease inhibitor. In the 14 subjects who entered the study on no antiretroviral treatment, NPZ-4 improvement was associated with decline in CSF HIV-1 RNA at both visits (p = 0.001 and p = 0.02), and those treated with zidovudine or indinavir had great...

  11. Non-Antiretroviral Microbicides for HIV Prevention

    Science.gov (United States)

    Scott, Yanille; Dezzutti, Charlene S.

    2016-01-01

    Non-antiretroviral microbicide candidates were previously explored as a female-controlled method of preventing sexual transmission of HIV. These products contained non-HIV specific active compounds that were ultimately found to disrupt the vaginal epithelium, cause increased immune activation in the female genital tract, disturb vaginal flora, and/or cause other irritation that precluded their use as vaginal microbicides. Due to the failure of these first-generation candidates, there was a shift in focus to developing HIV pre-exposure prophylaxis and microbicides containing small-molecule antiretrovirals. Even with the limited success of the antiretroviral-based microbicides in clinical evaluations and no commercially available products, there has been significant progress in microbicide research. The lessons learned from previous trials have given rise to more rigorous preclinical evaluation that aims to be better at predicting microbicide efficacy and safety and to novel formulation and delivery technologies. These advances have resulted in renewed interest in developing non-antiretroviral-based microbicides, such as broadly neutralizing antibodies (for example, VRC01) and anti-viral proteins (for example, Griffithsin), as options for persons not wanting to use antiretroviral drugs, and for their potential to prevent multiple sexually transmitted infections.

  13. Falling through the gaps: how should HIV programmes respond to families that persistently deny treatment to children?

    Directory of Open Access Journals (Sweden)

    Full Text Available Introduction: Children living with HIV rely on adult caregivers for access to HIV testing and care, including clinical monitoring and adherence to treatment. Yet, many caregivers confront barriers to ensuring children's care, including fear of disclosure of the child's or the parents’ HIV status, competing family demands, fluctuating care arrangements and broader structural factors such as entrenched poverty or alternative beliefs about HIV's aetiology and treatment. Thus, many children are “falling through the gaps” because their access to testing and care is mediated by guardians who appear unable or unwilling to facilitate it. These children are likely to suffer treatment failure or death due to their caregivers’ recalcitrance. Discussion: This Commentary presents three cases from paediatric HIV services in Zimbabwe that highlight the complexities facing health care providers in providing HIV testing and care to children, and discusses the implications as a child's rights issue requiring both legal and programmatic responses. The cases provide examples of how disagreements between family members about appropriate care, conflicts between a child and caregiver and religious objections to medical treatment interrupt children's engagement with HIV services. In all three cases, no social or legal mechanisms were in place for health staff to intervene and prevent “loss to follow up.” Conclusions: We suggest that conceptualizing this as a child's rights issue may be a useful way to raise the debate and move towards improved treatment access. Our cases reflect policy failure to facilitate access to children's HIV testing and treatment, and are likely to be similar across international settings. We propose sharing experiences and encouraging dialogue between health practitioners and global advocates for children's right to health to raise awareness that children are the bearers of rights even if they lack legal capacity, and that the

    Full Text Available Abstract Study design and aim This was a longitudinal chart review of a diverse group (cohort of patients undergoing HGH (Human Growth Hormone treatment. Clinical and radiological examinations were performed with the aim to identify the presence and progression of scoliosis. Methods and cohort 185 patients were recruited and a database incorporating the age at commencement, dose and frequency of growth hormone treatment and growth charts was compiled from their Medical Records. The presence of any known syndrome and the clinical presence of scoliosis were included for analysis. Subsequently, skeletally immature patients identified with scoliosis were followed up over a period of a minimum four years and the radiologic type, progression and severity (Cobb angle of scoliosis were recorded. Results Four (3.6% of the 109 with idiopathic short stature or hormone deficiency had idiopathic scoliosis (within normal limits for a control population and scoliosis progression was not prospectively observed. 13 (28.8% of 45 with Turner syndrome had scoliosis radiologically similar to idiopathic scoliosis. 11 (48% of 23 with varying syndromes, had scoliosis. In the entire cohort, the growth rates of those with and without scoliosis were not statistically different and HGH treatment was not ceased because of progression of scoliosis. Conclusion In this study, there was no evidence of HGH treatment being responsible for progression of scoliosis in a small number of non-syndromic patients (four. An incidental finding was that scoliosis, similar to the idiopathic type, appears to be more prevalent in Turner syndrome than previously believed.

    alterations are characterized by elevated levels of tumor necrosis factor alpha (TNF-α, interleukin 8 (IL-8, β2-microglobulin, IgA, IgG, IgM, haptoglobin and a1-acid glycoprotein. The goal of this double blind placebo-controlled study was to evaluate the effect of N-acetylcysteine supplementation on virological, immunological and inflammatory markers in 24 HIVinfected individuals who were taking their first anti-retroviral therapy. Eleven individuals were treated with anti-retroviral therapy plus placebo supplementation and thirteen were treated with anti-retroviral therapy plus 600 mg/day of Nacetylcysteine. The levels of the studied markers were evaluated at the day before and after 60, 120 and 180 days of treatment. In both groups a significant decrease in serum levels of TNF-α (p=0.0001, IL-6 (p>0.05, IL-8 (p=0.0001, b2 microglobulin (p=0.0005, IgA (p=0.007, IgG (p=0.001, IgM (p=0.0001, haptoglobin (p=0.0001 e α1-acid glycoprotein (p=0.012 was found due to anti-retroviral therapy. N-acetylcysteine supplementation had no additive or synergistic effects on the studied parameters. In conclusion, N-acetylcysteine had no additional beneficial effects, at least at the dose used in this study, on the treatment of HIV-infected patients under anti-retroviral therapy.

    Full Text Available Abstract Background India, China and Russia account for more than 62% of multidrug resistant tuberculosis (MDRTB globally. Within India, locations like urban metropolitan Mumbai with its burgeoning population and high incidence of TB are suspected to be a focus for MDRTB. However apart from sporadic surveys at watched sites in the country, there has been no systematic attempt by the Revised National Tuberculosis Control Programme (RNTCP of India to determine the extent of MDRTB in Mumbai that could feed into national estimates. Drug susceptibility testing (DST is not routinely performed as a part of programme policy and public health laboratory infrastructure, is limited and poorly equipped to cope with large scale testing. Methods From April 2004 to January 2007 we determined the extent of drug resistance in 724 {493 newly diagnosed, previously untreated and 231 first line treatment failures (sputum-smear positive at the fifth month after commencement of therapy} cases of pulmonary tuberculosis drawn from the RNTCP in four suboptimally performing municipal wards of Mumbai. The observations were obtained using a modified radiorespirometric Buddemeyer assay and validated by the Swedish Institute for Infectious Disease Control, Stockholm, a supranational reference laboratory. Data was analyzed utilizing SPSS 10.0 and Epi Info 2002. Results This study undertaken for the first time in RNTCP outpatients in Mumbai reveals a high proportion of MDRTB strains in both previously untreated (24% and treatment-failure cases (41%. Amongst new cases, resistance to 3 or 4 drug combinations (amplified drug resistance including isoniazid (H and rifampicin (R, was greater (20% than resistance to H and R alone (4% at any point in time during the study. The trend for monoresistance was similar in both groups remaining highest to H and lowest to R. External quality control revealed good agreement for H and R resistance (k = 0.77 and 0.76 respectively. Conclusion

    Full Text Available Abstract Background Combination antiretroviral (AR therapy continues to be the mainstay for HIV treatment. However, antiretroviral drug nonadherence can lead to the development of resistance and treatment failure. We have designed nanoparticles (NP that contain three AR drugs and characterized the size, shape, and surface charge. Additionally, we investigated the in vitro release of the AR drugs from the NP using peripheral blood mononuclear cells (PBMCs. Methods Poly-(lactic-co-glycolic acid (PLGA nanoparticles (NPs containing ritonavir (RTV, lopinavir (LPV, and efavirenz (EFV were fabricated using multiple emulsion-solvent evaporation procedure. The nanoparticles were characterized by electron microscopy and zeta potential for size, shape, and charge. The intracellular concentration of AR drugs was determined over 28 days from NPs incubated with PBMCs. Macrophages were imaged by fluorescent microscopy and flow cytometry after incubation with fluorescent NPs. Finally, macrophage cytotoxicity was determined by MTT assay. Results Nanoparticle size averaged 262 ± 83.9 nm and zeta potential -11.4 ± 2.4. AR loading averaged 4% (w/v. Antiretroviral drug levels were determined in PBMCs after 100 μg of NP in 75 μL PBS was added to media. Intracellular peak AR levels from NPs (day 4 were RTV 2.5 ± 1.1; LPV 4.1 ± 2.0; and EFV 10.6 ± 2.7 μg and continued until day 28 (all AR ≥ 0.9 μg. Free drugs (25 μg of each drug in 25 μL ethanol added to PBMCs served as control were eliminated by 2 days. Fluorescence microscopy and flow cytometry demonstrated phagocytosis of NP into monocytes-derived macrophages (MDMs. Cellular MTT assay performed on MDMs demonstrated that NPs are not significantly cytotoxic. Conclusion These results demonstrated AR NPs could be fabricated containing three antiretroviral drugs (RTV, LPV, EFV. Sustained release of AR from PLGA NP show high drug levels in PBMCs until day 28 without cytotoxicity.

    The course of disease among HIV-2, HIV-1, and HIV-1/2 dually infected patients is different. We investigated the macrophage activation marker soluble CD163 (sCD163) dynamics in 212 HIV-1, HIV-2, and HIV-1/2 dually infected patients. There were no differences in sCD163 levels at baseline or during follow-up without antiretroviral therapy (ART). At follow-up on ART, median sCD163 levels were decreased for HIV-1-infected patients (P < 0.001), but not among HIV-2 (P = 0.093) or HIV-1/2 dually infected patients (P = 0.145). The larger decrease in sCD163 levels among HIV-1-infected patients during ART may indicate an HIV type-dependent differential effect of ART on macrophage activation during HIV infection.

    Full Text Available Background: Within the United Kingdom’s ‘Transforming Rehabilitation’ agenda, reshaping drug and alcohol interventions in prisons is central to the Government’s approach to addressing substance dependence in the prison population and reduce reoffending. To achieve this, a through-care project to support offenders following release, ‘Gateways’, is taking place providing ‘through the gate’ support to released offenders, including help with organising accommodation, education and employment, and access to a peer supporter. In addition, Gateways is providing access to an evidence-based computer-assisted therapy (CAT programme for substance misuse, Breaking Free Health & Justice (BFHJ. Developed in partnership with the Ministry of Justice (MoJ National Offender Management Services (NOMS, and based on a community version of the programme, Breaking Free Online (BFO, BFHJ provides access to clinically-robust techniques based on cognitive behavioural therapy (CBT and promotes the role of technology-enhanced approaches in recovery from substance misuse. The BFHJ programme is provided via ‘Virtual Campus’ (VC, a secure, web-based learning environment delivered by NOMS and the Department for Business, Innovation and Skills, which has no links to websites not approved by MoJ, and provides prisoners with access to online training courses around work and skills. Providing BFHJ on VC makes the programme the world’s first online healthcare programme to be provided in prisons. Aims: Although here is an emerging evidence-base for the effectiveness of the community version of the BFO programme and its implementation within community treatment settings (Davies, Elison, Ward, & Laudet, 2015; Elison, Davies, & Ward, 2015a, 2015b; Elison, Humphreys, Ward, & Davies, 2013; Elison, Ward, Davies, Lidbetter, et al., 2014; Elison, Ward, Davies, & Moody, 2014, its potential within prison settings requires exploration.

    The effects of HIV/AIDS have been far-reaching in Africa. Beyond adverse health outcomes and the tremendous toll on life, AIDS has serious economic impacts on households, increasing livelihood insecurity while simultaneously depleting socio-economic resources. Although microfinance is believed to have the potential to mitigate the economic impacts of HIV by helping affected households and communities better prepare for and cope with HIV-related economic shocks, little empirical research exists on this subject. This qualitative study examines the socio-economic impacts of economic strengthening activities on people living with HIV (PLHIV) in the era of increased access to anti-retroviral therapy to determine if savings-led, community-managed microfinance is a justified activity for HIV programmes. Findings from a village savings and loan programme, implemented by CARE International in Cote d'Ivoire, revealed that when appropriate medical treatment is available PLHIV are capable of participating in and benefit from microfinance activities, which increased HIV-positive clients' access to money and economic self-sufficiency. By bringing individuals with similar experiences together, savings and loan groups also acted as self-support groups providing psychosocial support while reducing stigmatisation and increasing members' sense of dignity and self-worth.

    Full Text Available Global commitments aim to provide antiretroviral therapy (ART to 15 million people living with HIV by 2015, and recent studies have demonstrated the potential for widespread ART to prevent HIV transmission. Increasingly, countries are adapting their national guidelines to start ART earlier, for both clinical and preventive benefits. To maximize the benefits of ART in resource-limited settings, six key principles need to guide ART choice: simplicity, tolerability and safety, durability, universal applicability, affordability and heat stability. Currently available drugs, combined with those in late-stage clinical development, hold great promise to simplify treatment in the short term. Over the longer term, newer technologies, such as long-acting formulations and nanotechnology, could radically alter the treatment paradigm. This commentary reviews recommendations made in an expert consultation on treatment scale up in resource-limited settings.

    Full Text Available Background: There are limited data on the failure of second-line antiretroviral therapy (ART and the use of third-line ART in people living with HIV in resource-limited settings. Since 2011, the Médecins Sans Frontières (MSF HIV/tuberculosis programme in Mumbai, India, has been providing third-line ART to patients in care. Objective: To describe the experiences and programmatic challenges during management of suspected second-line ART failure and third-line ART therapy for patients living with HIV, including the use of HIV viral load (VL testing. Design: This was a retrospective, observational cohort study of patients with suspected second-line ART treatment failure, who were followed for at least 12 months between January 2011 and March 2014. Results: A total of 47 patients with suspected second-line failure met the inclusion criteria during the study period. Twenty-nine of them (62% responded to enhanced adherence support, had a subsequent undetectable VL after a median duration of 3 months and remained on second-line ART. The other 18 patients had to be initiated on a third-line ART regimen, which consisted of darunavir–ritonavir, raltegravir, and one or more appropriate nucleoside or nucleotide reverse transcriptase inhibitors, based on the results of HIV genotype testing. Of the 13 patients for whom follow-up VL results were available, 11 achieved virological suppression after a median duration of 3 months on third-line ART (interquartile range: 2.5–3.0. No serious treatment-related adverse events were recorded. Conclusions: With intensive counselling and adherence support in those suspected of failing second-line ART, unnecessary switching to more expensive third-line ART can be averted in the majority of cases. However, there is an increasing need for access to third-line ART medications such as darunavir and raltegravir, for which national ART programmes should be prepared. The cost of such medications and inadequate access to VL

    Despite being one of the worst affected sectors in South Africa, the mining sector has proven to be one of the most active in intervention efforts in the fight against HIV and AIDS (Ellis, 2007). Owing to low uptake rates of antiretroviral therapy (ART) in mining companies in recent years (Connelly & Rosen, 2006) and the positive relationship between attitudes towards ART and ART uptake (Cooper et al., 2002; Horne, Cooper, Gellaitry, Leake, & Fisher, 2007), this study sought to describe and investigate the psychosocial and behavioural correlates of attitudes towards ART in a sample of South African mineworkers. A total of 806 mineworkers from a large South African mine participated in this quantitative study. Despite a high rate of HIV testing behaviour (83.0%) as well as favourable attitudes towards ART, analysis indicated that temporary employees and contractors were more vulnerable in terms of HIV risk, HIV testing behaviours and ART knowledge and attitudes. Employees who had more positive attitudes towards ART were more knowledgeable of ART and, importantly, had a more favourable attitude towards the mine's HIV/AIDS treatment programme. These findings are discussed in relation to the low ART uptake rates in this context and recommendations for the improvement of ART uptake amongst employees at this mining site. PMID:23237682

    High level adherence to antiretroviral therapy (ART) is required to achieve and maintain suppression of HIV replication. Although directly observed therapy (DOT) has been suggested as an intervention to improve adherence, there is a paucity of data describing the attitudes and beliefs regarding DOT for ART among HIV-infected individuals. This study was designed to evaluate the acceptability and psychometric properties of a survey instrument for use in assessing barriers and facilitators of adherence to ART DOT in prison. From July 1, 1999 to April 1, 2000, we piloted an interviewer-administered questionnaire to assess health beliefs and attitudes regarding HIV treatment among 65 HIV-infected prison inmates receiving one or more of their antiretrovirals via directly observed therapy (DOT). The first 24 participants were administered the questionnaire to determine the feasibility of surveying prisoners in a correctional setting. There were no adherence data collected on these participants. The remaining 41 participants had their adherence measured in addition to receiving the questionnaire. Thirty-one were included in the final analysis because 10 did not complete the study. Multiple antiretroviral adherence measures (electronic device medication monitoring [eDEM] caps, medication administration records [MARs], and pill counts) were assessed among a subset of the participants (n = 31) and correlated to the instrument response items. The median internal consistency reliability coefficient for the multi-item scales was 0.79. The strongest correlation between inmates' beliefs and their adherence was between "positive beliefs about protease inhibitors" and the MAR adherence measure (r = 0.72; p < 0.001). This study provides preliminary support for the psychometric properties of the survey in this correctional setting. PMID:16789854

    We present a large-scale social marketing programme of insecticide-treated nets in 2 rural districts in southwestern Tanzania (population 350,000) and describe how the long-term child health and survival impact will be assessed. Formative and market research were conducted in order to understand community perceptions, knowledge, attitudes and practice with respect to the products to be socially marketed. We identified Zuia Mbu (Kiswahili for 'prevent mosquitoes') as a suitable brand name for both treated nets and single-dose insecticide treatment sachets. A mix of public and private sales outlets is used for distribution. In the first stage of a stepped introduction 31 net agents were appointed and trained in 18 villages: 15 were shop owners, 14 were village leaders, 1 was a parish priest and 1 a health worker. For net treatment 37 young people were appointed in the same villages and trained as agents. Further institutions in both districts such as hospitals, development projects and employers were also involved in distribution. Promotion for both products was intense and used a variety of channels. A total of 22,410 nets and 8072 treatments were sold during the first year: 18 months after launching, 46% of 312 families with children aged under 5 years reported that their children were sleeping under treated nets. A strong evaluation component in over 50,000 people allows assessment of the long-term effects of insecticide-treated nets on child health and survival, anaemia in pregnancy, and the costs of the intervention. This evaluation is based on cross-sectional surveys, and case-control and cohort studies. PMID:10492745

    Background Limpopo Province is one of the hardest hit by tuberculosis and human immune virus infections in the country. The province has been implementing a directly observed treatment strategy since 1996. However, the cure rate was 64% in 2015 and remains far from the set target by the World Health Organization of 85%. Poor health-care seeking and adherence behaviours were identified as major risk behaviours. Aim To apply a Community-Based Participatory Research (CBPR) approach in identifying barriers and facilitators to health-care seeking and adherence to treatment, and to determine strategies and messages in order to inform the design of an adapted intervention programme. Setting This study was conducted in three districts in the Limpopo Province, Capricorn, Mopani and Sekhukhune districts. Methods The community participatory research approach was applied. Purposive sampling was used to sample participants. Focus group discussions were used to collect data. Participatory analysis was used comparing findings within and across all the participants. Results A total of 161 participated in the study. Participants included coordinators, professional nurses, supporters and patients. Major modifiable behavioural-related barriers were lack of knowledge about tuberculosis, misinformation and misperceptions cultural beliefs, stigma and refusal of treatment support. Environment-related barriers were attitudes of health workers, lack of support by family and community, lack of food and use of alcohol and drugs. Strategies and messages included persuasive and motivational messages to promote healthy behaviour. Conclusion Joint programmatic collaboration between the community and academic researchers is really needed for interventions to address the needs of the community.

    extension study. Only a third of the PBC patients were able to tolerate the lopinavir but those maintained on tenofovir, emtricitabine and lopinavir experienced sustained and clinically meaningful reduction in hepatic biochemistry. While we await the histological and virological evaluation, it is clear that better tolerated regimens of antiretroviral treatment will be required in future clinical trials. PMID:26755881

    Full Text Available BACKGROUND: In adults it is well documented that there are substantial losses to the programme between HIV testing and start of antiretroviral therapy (ART. The magnitude and reasons for loss to follow-up and death between HIV diagnosis and start of ART in children are not well defined. METHODS: We searched the PubMed and EMBASE databases for studies on children followed between HIV diagnosis and start of ART in low-income settings. We examined the proportion of children with a CD4 cell count/percentage after after being diagnosed with HIV infection, the number of treatment-eligible children starting ART and predictors of loss to programme. Data were extracted in duplicate. RESULTS: Eight studies from sub-Saharan Africa and two studies from Asia with a total of 10,741 children were included. Median age ranged from 2.2 to 6.5 years. Between 78.0 and 97.0% of HIV-infected children subsequently had a CD4 cell count/percentage measured, 63.2 to 90.7% of children with an eligibility assessment met the eligibility criteria for the particular setting and time and 39.5 to 99.4% of the eligible children started ART. Three studies reported an association between low CD4 count/percentage and ART initiation while no association was reported for gender. Only two studies reported on pre-ART mortality and found rates of 13 and 6 per 100 person-years. CONCLUSION: Most children who presented for HIV care met eligibility criteria for ART. There is an urgent need for strategies to improve the access to and retention to care of HIV-infected children in resource-limited settings.
