    Full Text Available Sclerosing colangitis (SC due to cytomegalovirus (CMV is very rare. It has been described mainly in immunocompromised patients. Currently, in HIV infected patients it is exceptional. The most of cases belong to pre-highly active antiretroviral therapy (pre-HAART and those cases were in stage AIDS with less than 100 CD4/μl. The most frequently involved pathogen in pre-HAART period was Cryptosporidium parvum (30-57% and CMV (10-30%; in late HAART period this information are unaware. CMV has been implicated as a possible etiological agent in primary SC partly because of the ability to cause liver damage and its relationship with smooth muscle antibodies. The most effective treatment for SC was the combination of antiretroviral therapy and endoscopic retrograde cholangiopancreatography with sphincterotomy and stent placement. Following, we present the first case of late HAART period which describes a SC extrahepatic without papillary stenosis with CMV as the only cause and clinical presentation of HIV infection in a woman with 177 CD4/μl.

    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.

    @@ 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.

    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

    In economically developed countries, AIDS-related lymphoma (ARL) accounts for a large proportion of malignances in HIV-infected individuals. Since the introduction of highly active anti-retroviral therapy (HAART) in 1996, epidemiology and prognosis of ARL have changed. While there is a slight increase in the incidence of Hodgkin’s lymphoma in HIV-infected individuals, use of HAART has contributed to a decline in the incidence of non-Hodgkin’s lymphoma (NHL) and also a decrease in the overall ...

    Full Text Available INTRODUCTION: Lipodystrophy is related to the use of highly active antiretroviral therapy (HAART and can cause aesthetic stigma and increase the risk of developing cardiovascular diseases. Physical activity may be a valid alternative for the treatment and prevention of lipodystrophy. However, few studies address this issue. The objective of this study was to assess lipodystrophy related to highly active antiretroviral therapy in HIV/AIDS patients with different physical activity habits. METHODS: The sample was composed of 42 HIV/AIDS patients taking HAART medication who were visiting the Counseling and Testing Center (CTC in Presidente Prudente. The level of physical activity was obtained using the International Physical Activity Questionnaire (IPAQ; lipodystrophy was diagnosed using a self-report questionnaire that was administered to the patient and then followed up by medical confirmation. The percentage of trunk fat was estimated by dual X-Ray absorptiometry (DEXA. Information about sex, age, length of HAART treatment, CD4+ T lymphocyte count (CD4 and viral load was also collected. RESULTS: A higher prevalence of lipodystrophy was observed in the sedentary group when compared to the physically active group, which indicates that physical activity may be a protective factor in relation to the occurrence of lipodystrophy. The group that had a higher CD4 had a higher proportion of lipodystrophy and a higher proportion of younger and physically active individuals. The patients with lipodystrophy had a higher percentage of trunk fat and were more sedentary than active individuals. CONCLUSIONS: A physically active lifestyle has a protective effect against the occurrence of lipodystrophy related to HAART.

    Full Text Available Abstract Background The introduction of combination antiretroviral therapy (ART has resulted in striking reductions in HIV-related mortality. Despite increased availability of ART, children remain a neglected population. This may be due to concerns that failure to adhere appears to be related to continued viral replication, treatment failure and the emergence of drug-resistant strains of HIV. This study determines the rates and factors associated with adherence to Antiretroviral (ARV Drug therapy in HIV-infected children who were receiving Highly Active Antiretroviral Therapy (HAART in Addis Ababa, Ethiopia in 2008. Methods A cross-sectional study was conducted in five hospitals in Addis Ababa from February 18 – April 28, 2008. The study population entailed parents/caretaker and index children who were following ART in the health facilities. A structured questionnaire was used for data collection. Results A total of 390 children respondents were included in the study with a response rate of 91%. The majority, equaling 205 (52.6% of the children, were greater than 9 years of age. Fifty five percent of the children were girls. A total of 339 children (86.9% as reported by caregivers were adherent to antiretroviral drugs for the past 7 days before the interview. Numerous variables were found to be significantly associated with adherence: children whose parents did not pay a fee for treatment [OR = 0.39 (95%CI: 0.16, 0.92], children who had ever received any nutritional support from the clinic [OR = 0.34 (95%CI: 0.14, 0.79] were less likely to adhere. Whereas children who took co-trimoxazole medication/syrup besides ARVs [OR = 3.65 (95%CI: 1.24, 10.74], children who did not know their sero-status [OR = 2.53 (95%CI: 1.24, 5.19] and children who were not aware of their caregiver's health problem [OR = 2.45 (95%CI: 1.25, 4.81] were more likely to adhere than their counterparts.

    Objective Little is known about the degree to which widespread use of antiretroviral therapy in a community reduces uninfected individuals’ risk of acquiring HIV. We estimated the degree to which the probability of HIV infection from an infected partner (the infectivity) declined following the introduction of highly active antiretroviral therapy (HAART) in San Francisco. Design Homosexual men from the San Francisco Young Men’s Health Study, who were initially uninfected with HIV, were asked about sexual practices, and tested for HIV antibodies at each of four follow-up visits during a 6-year period spanning the advent of widespread use of HAART (1994 to 1999). Methods We estimated the infectivity of HIV (per-partnership probability of transmission from an infected partner) using a probabilistic risk model based on observed incident infections and self-reported sexual risk behavior, and tested the hypothesis that infectivity was the same before and after HAART was introduced. Results A total of 534 homosexual men were evaluated. Decreasing trends in HIV seroincidence were observed despite increases in reported number of unprotected receptive anal intercourse partners. Conservatively assuming a constant prevalence of HIV infection between 1994 and 1999, HIV infectivity decreased from 0.120 prior to widespread use of HAART, to 0.048 after the widespread use of HAART – a decline of 60% (P = 0.028). Conclusions Use of HAART by infected persons in a community appears to reduce their infectiousness and therefore may provide an important HIV prevention tool. PMID:15090833

    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

    We evaluated retrospectively an automated method for the separate detection of subcutaneous and visceral fat in the abdominal region by magnetic resonance studies in HIV-positive patients on highly active antiretroviral therapy. The patients were divided into four different groups: lipoatrophy, lipohypertrophy, mixed and the control group. The use of software for the automated detection of abdominal compartment visceral adipose tissue (VAT), total adipose tissue (TAT) and subcutaneous adipose tissue (SAT) was compared to manual evaluation methods (fuzzy C-mean). The results of ROC analysis showed that the parameters, particularly the VAT, are better than the VAT/TAT and at identifying patients with the symptoms of abdominal fat accumulation. A sensitivity of 80.3% and a specificity of 79.5% resulted from a threshold VAT value of >87 cm(2). Moreover, the manual evaluation method was shown to provide greater values for VAT and the VAT/TAT ratio than those given by the automated method. In the present study, a rapid MRI protocol for the detection and assessment of the course of lipodystrophy was presented and tested on a group of patients with signs of HALS, as well as on an antiretroviral naïve control group.

    This is a report of an atypical case of progressive outer retinal necrosis (PORN) and the effect of highly active antiretroviral therapy (HAART) on the clinical course of viral retinitis in an acquired immunodeficiency syndrome (AIDS) patient. A 22-year-old male patient infected with human immunodeficiency virus (HIV) presented with unilaterally reduced visual acuity and a dense cataract. After cataract extraction, retinal lesions involving the peripheral and macular areas were found with perivascular sparing and the mud-cracked, characteristic appearance of PORN. He was diagnosed as having PORN based on clinical features and was given combined antiviral treatment. With concurrent HAART, the retinal lesions regressed, with the regression being accelerated by further treatment with intravenous acyclovir and ganciclovir. This case suggests that HAART may change the clinical course of PORN in AIDS patients by improving host immunity. PORN should be included in the differential diagnosis of acute unilateral cataract in AIDS patients.

  8. Immune reconstitution inflammatory syndrome after initiating highly active antiretroviral therapy in HIV-infected children

    International Nuclear Information System (INIS)

    The outcome of HIV infection has improved since the widespread availability of highly active antiretroviral therapy (HAART). Some patients, however, develop a clinical and radiological deterioration following initiation of HAART due to either the unmasking of occult subclinical infection or an enhanced inflammatory response to a treated infection. This phenomenon is believed to result from the restored ability to mount an immune response and is termed immune reconstitution inflammatory syndrome (IRIS) or immune reconstitution disease. IRIS is widely reported in the literature in adult patients, most commonly associated with mycobacterial infections. There is, however, a paucity of data documenting the radiological findings of IRIS in children. Radiologists need to be aware of this entity. As a diagnosis of exclusion it is essential that the radiological findings be assessed in the context of the clinical presentation. This article reviews the common clinical and radiological manifestations of IRIS in HIV-infected children. (orig.)

    Chronic HIV infection is associated with persistent immune activation and inflammation even among patients virologically suppressed on antiretroviral therapy for years. Chronic immune activation has been associated with poor outcomes--both AIDS-defining and non-AIDS-defining clinical events--and persistent CD4 T-cell depletion. The cause of chronic immune activation in well-controlled HIV infection is unknown. Proposed drivers include residual viral replication, microbial translocation, and coinfecting pathogens. Therapeutic interventions targeting immune activation are emerging, from approaches that interfere directly with activation and inflammatory pathways to those that prevent microbial translocation or decrease the availability of host target cells for the virus. In the context of the disappointing results of the interleukin-2 trials, the main challenges to developing these disease-modifying therapies include identifying an adequate target population and choosing surrogate endpoints that will provide positive proof-of-concept that the interventions will translate into long-term clinical benefit before embarking on large clinical endpoint trials.

    Full Text Available Abstract Background Highly active antiretroviral therapy produces a significant decrease in HIV-1 replication and allows an increase in the CD4 T-cell count, leading to a decrease in the incidence of opportunistic infections and mortality. However, the cost, side effects and complexity of antiretroviral regimens have underscored the immediate need for additional therapeutic approaches. Statins exert pleiotropic effects through a variety of mechanisms, among which there are several immunoregulatory effects, related and unrelated to their cholesterol-lowering activity that can be useful to control HIV-1 infection. Methods/design Randomized, double-blinded, placebo controlled, single-center, phase-II clinical trial. One hundred and ten chronically HIV-1-infected patients, older than 18 years and naïve for antirretroviral therapy (i.e., without prior or current management with antiretroviral drugs will be enrolled at the outpatient services from the most important centres for health insurance care in Medellin-Colombia. The interventions will be lovastatin (40 mg/day, orally, for 12 months; 55 patients or placebo (55 patients. Our primary aim will be to determine the effect of lovastatin on viral replication. The secondary aim will be to determine the effect of lovastatin on CD4+ T-cell count in peripheral blood. As tertiary aims we will explore differences in CD8+ T-cell count, expression of activation markers (CD38 and HLA-DR on CD4 and CD8 T cells, cholesterol metabolism, LFA-1/ICAM-1 function, Rho GTPases function and clinical evolution between treated and not treated HIV-1-infected individuals. Discussion Preliminary descriptive studies have suggested that statins (lovastatin may have anti HIV-1 activity and that their administration is safe, with the potential effect of controlling HIV-1 replication in chronically infected individuals who had not received antiretroviral medications. Considering that there is limited clinical data available on

    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.

    Full Text Available Abstract Background Use of highly active antiretroviral therapy (HAART, a triple-drug combination, in HIV-infected pregnant women markedly reduces mother to child transmission of HIV and decreases maternal morbidity. However, there remains uncertainty about the effects of in utero exposure to HAART on foetal development. Methods Our objectives were to investigate whether in utero exposure to HAART is associated with low birth weight and/or preterm birth in a population of South African women with advanced HIV disease. A retrospective observational study was performed on women with CD4 counts ≤250 cells/mm3 attending antenatal antiretroviral clinics in Johannesburg between October 2004 and March 2007. Low birth weight ( Results Among HAART-unexposed infants, 27% (60/224 were low birth weight compared with 23% (90/388 of early HAART-exposed (exposed 3 increase, 95% CI 0.45-0.71, p 3 increase, 95% CI 0.55-0.85, p = 0.001. HAART exposure was associated with an increased preterm birth rate (15%, or 138 of 946, versus 5%, or seven of 147, in unexposed infants, p = 0.001, with early nevirapine and efavirenz-based regimens having the strongest associations with preterm birth (AOR 5.4, 95% CI 2.1-13.7, p Conclusions In this immunocompromised cohort, in utero HAART exposure was not associated with low birth weight. An association between NNRTI-based HAART and preterm birth was detected, but residual confounding is plausible. More advanced immunosuppression was a risk factor for low birth weight and preterm birth, highlighting the importance of earlier HAART initiation in women to optimize maternal health and improve infant outcomes.

    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 Abstract Background Rhodococcus equi (R.equi is an acid fast, GRAM + coccobacillus, which is widespread in the soil and causes pulmonary and extrapulmonary infections in immunocompromised people. In the context of HIV infection, R.equi infection (rhodococcosis is regarded as an opportunistic disease, and its outcome is influenced by highly active antiretroviral therapy (HAART. Case presentation We report two cases of HIV-related rhodococcosis that disseminated despite suppressive HAART and anti-rhodococcal treatment; in both cases there was no immunological recovery, with CD4+ cells count below 200/μL. In the first case, pulmonary rhodococcosis presented 6 months after initiation of HAART, and was followed by an extracerebral intracranial and a cerebral rhodococcal abscess 1 and 8 months, respectively, after onset of pulmonary infection. The second case was characterized by a protracted course with spread of infection to various organs, including subcutaneous tissue, skin, colon and other intra-abdominal tissues, and central nervous system; the spread started 4 years after clinical resolution of a first pulmonary manifestation and progressed over a period of 2 years. Conclusions Our report highlights the importance of an effective immune recovery, despite fully suppressive HAART, along with anti-rhodococcal therapy, in order to clear rhodococcal infection.

    Full Text Available The aim of this study was to assess and compare quantitatively the presence of S100+ Langerhans cells (LC by immunochemistry techniques in HIV+ and HIV- gingivitis and periodontitis subjects. Additionally, it aimed to evaluate the correlation among densities of these cells with CD4+ and CD8+ T cells, and viral load levels in HIV+ subjects, all using Highly Active Antiretroviral Therapy (HAART. The samples were allocated into four groups: 1 15 subjects with moderate chronic periodontitis (MCP, HIV+; 2 15 subjects with MCP, HIV-; 3 10 subjects with gingivitis (G, HIV+; and 4 10 subjects with G, HIV-. The S100+ cells were assessed in the pocket epithelium, gingival epithelium, and lamina propria. A statistically significant increase of total S100+ cells in HIV+ periodontitis subjects was observed in relation to HIV- periodontitis subjects. No increase of S100+ cells with increased inflammation was observed. No statistically significant correlation among S100+ cells and blood levels of CD4, CD8, and viral load was observed. In conclusion, the use of HAART can aid in achieving viral loads, and it is suggested that it may prevent the destruction of the LC.

    HIV-related eye disease can be classified as retinal HIV microangiopathy, opportunistic infections, neuro-ophthalmic manifestations and unusual malignancies. There is a 52-100% lifetime accumulative risk of HIV patients developing eye problems. Seventy-seven per cent of patients with ocular manifestations of HIV had CD4 counts 100 cells/μL for a minimum of three months. Despite HAART, patients with a CD4 count PORN), less commonly toxoplasmosis, pneumocystis and cryptococcus. Malignancies associated with HIV include Kaposi's sarcoma and conjunctival squamous cell carcinoma. Cranial nerve palsies, optic disc swelling and atrophy are characteristic neuro-ophthalmic features. They usually occur secondary to meningitis/encephalitis (from cryptococcus and tuberculosis). With the advent of HAART, new complications have developed in CMV retinitis: immune recovery uveitis (IRU) and cystoid macula oedema (CMO). Immune recovery uveitis occurs in 71% of patients if HAART is started before the induction of the anti-CMV treatment. However, this is reduced to 31% if HAART is started after the induction treatment. Molluscum contagiosum and Kaposi's sarcoma can spontaneously resolve on HAART. Highly active anti-retroviral therapy has reduced the frequencies of opportunistic infections and improved the remission duration in HIV patients. PMID:24756590

The aim of the present study was to assess the cost- effectiveness of treatment with HAART in a large clinical cohort of naïve adults to determine the potential role of single-tablet regimens in the management of patients with human immunodeficiency virus (HIV. An incremental cost-effectiveness ratio analysis was performed, including a quality-adjusted life year approach. Results: In total, 741 patients (females comprising 25.5% were retrospectively included. The mean age was 39 years, the mean CD4 cell count was 266 cells/µL, and the mean viral load was 192,821 copies/mL. The most commonly used backbone was tenofovir + emtricitabine (77.6%; zidovudine + lamivudine was used in 10%, lamivudine + abacavir in 3%, and other nucleoside reverse transcriptase inhibitor (NRTI or NRTI-free regimens in 9.4% of patients. NNRTIs were used in 52.8% of cases, boosted protease inhibitors in 44.1%, and unboosted protease inhibitors and integrase inhibitors in 0.7% and 2.4%, respectively. Starting therapy at CD4 >500 cells/µL and CD4 351–500 cells/µL rather than at <201 cells/µL was the more cost-effective approach. The same consideration was not true comparing current indications with the possibility to start HAART at any CD4 value (eg, >500 cells per µL; in this case, the incremental cost-effectiveness ratio value was €199,130 per quality-adjusted life year gained, a higher value than the one suggested in guidelines.

    From December 2005 through August 2008, we provided community-based accompaniment with supervised antiretroviral therapy (CASA) to impoverished individuals starting highly active antiretroviral therapy. Adherence support was provided for 18 months by a community-based team comprised of several nurses and two types of community health workers: field supervisors and directly observed therapy (DOT) volunteers. To complement our quantitative data collection in 2008 using purposive sampling, we conducted two gender-mixed focus group discussions with 13 CASA patient participants and 13 DOT volunteers from Lima, Peru to identify the mediating mechanisms by which CASA improved well-being, and to understand the benefits of the intervention, as perceived by these individuals. Using standard qualitative methods for the review and analysis of transcripts and interview notes, we identified central themes and developed a coding scheme for categorising participants' statements. Two individuals blinded to each other's coding, coded interview transcripts for theme and content from which a third reviewer compared their coding to arbitrate discrepancies. Additional domains were added if necessary and all domains were integrated into a theoretical scheme. Among the forms of support delivered by the CASA team, DOT volunteers reported emotional support, instrumental support, directly observed therapy, building trust, education, advocacy, exercise of moral authority and preparation for transition off CASA support. CASA participants described outcomes of improved adherence, ability to resume social roles, increased self-efficacy, hopefulness, changes in non-HIV-related behaviour, reduced internalised and externalised stigma, as well as ability to disclose. Both sets of focus group participants highlighted remaining challenges after completion of CASA support: stigma in the community, difficulties achieving economic recovery and persistent barriers to health services.

    Opportunistic diseases cause substantial morbidity and mortality to human immunodeficiency virus (HIV)-infected patients. Highly active antiretroviral therapy (HAART) leading to immune reconstitution is the most effective treatment of preventing opportunistic diseases. This retrospective study established an epidemiologic profile of opportunistic diseases 10 years after the introduction of HAART. The HIV antiretroviral therapy-naive patients matching inclusion criteria were included. The primary outcome was the prevalence of opportunistic diseases. From January 1, 2002 to September 30, 2010, 654 opportunistic diseases were identified in 458 patients. Pulmonary tuberculosis, herpes zoster, cerebral toxoplasmosis, oral candidiasis, and severe pneumonia accounted for 22.05%, 15.94%, 14.19%, 14.19%, and 9.39%, respectively. Cryptococcal meningitis and pneumocystosis accounted for 0.44% and 0.21%, respectively. The prevalence of opportunistic diseases in Gabon remains high. New guidelines emphasize the importance of initiating antiretroviral therapy early to reconstitute the immune system, and reduce disease risk, and treat the primary opportunistic infection of pulmonary tuberculosis.

    Full Text Available Background: Lupus anticoagulant (LA is a heterogeneous group of antibodies that causes a variety of clinical and laboratory effects; has been described in infections such as human immunodeficiency virus. LA has not been previously described in Nigerians with human immunodeficiency virus infection on highly active antiretroviral therapy (HAART. Aim: To determine the frequency of LA in patients infected with the human immunodeficiency virus on HAART. Methods: Cross sectional study of patients with human immunodeficiency virus infection undergoing HAART at a tertiary hospital in Nigeria. Screening for LA was done using the activated partial thromboplastin time (aPTT and kaolin clotting time (KCT. Mixing experiments were conducted on samples with prolonged clotting time. KCT ratio was calculated. A positive result was taken as KCT ratio greater than or equal to 1.2. Fisher′s exact test was used to test the association between LA and sex. Association between aPTT and KCT was tested according to Pearson. P-value < 0.05 was considered significant. Results: Fifty-eight patients aged 18- 60 years were studied, comprising of 28 males (mean age 40.50 plus/minus 8.8 years and 30 females (mean age 35.4 plus/minus 9.02. Frequency of LA among human immunodeficiency infected patients was 5.2%, (frequency in males and females were 3.6 and 6.7 % respectively. This was lower than 46% reported in patients not on HAART. There was no statistically significant difference in LA prevalence between males and females P greater than0.05. A positive correlation was observed between the clotting tests aPTT and KCT (r is equal to 0.9406, p less than 0.0001. Conclusion: HAART may prevent development of LA in HIV-infected patients.

    Objective To investigate the response on late stage Chinese AIDS patients after highly active antiretroviral therapy (HAART).Methods From October 2002 to March 2004, 20 cases of late stage Chinese AIDS patients were selected to participate in this opened and randomised study, we purposely chose those with CD4+ T cell counts < 100/mm3. All of them had one or two opportunistic infections and none had been treated with anti-HIV drugs. All patients were tested with CD4+(naive CD4+ T cell defined by CD45RA+ and CD62L+, memory CD4+ T cell defined by CD45RA-), CD8+ T cell,plasma HIV viral load, and clinical manifestations on before, during, and after HAART (5 different regimes) on 1, 3, 6, 9,and 12 months.Results Before HAART mean CD4+ T cell counts were 32 ± 31 (range 2-91)/mm3, and plasma HIV viral load were 5.07±0.85(range 2.04-5.70) log copies/mL. In 1 month's time patients treated with HAART had mean CD4+ and CD8T cell counts increasing rapidly. After 1 month the increasing speed turned to slow down, but HIV viral load decreased predominantly within the first 3 months. The major part of increasing CD4+ T cells were memory CD4+ T cells, as for naive CD4+ T cells increasing low and slow. Clinical symptoms and signs improved, and opportunistic infections reduced. The quality of life will be far much better than before. Each patient was followed for 12 months, and had finished 12 months' HAART.Conclusion This is the first report in China that late stage Chinese AIDS patients after HAART could have their immune reconstitution. The regular pattern is similar to what had been reported in Western countries and also in China. So it is worth to treat late stage Chinese AIDS patients with HAART.

    Full Text Available Background: The risk of squamous intra-epithelial lesions (SIL is higher in HIV-positive women. As these women begin to live longer due to highly active antiretroviral therapy (HAART, their risk of cervical cancer may increase. Few data exist regarding the effect of HAART on the incidence and progression of SIL in HIV-positive African women. The aim of this study was to evaluate the effect of HAART on the incidence and progression of SIL in HIV-positive women in South Africa. Methods: A prospective observational study of HIV-seropositive women was conducted over 5 years in an HIV treatment clinic in Johannesburg, South Africa. The participants consisted of 601 women on and off HAART who had repeat Pap smears greater than 6 months apart. The effect of HAART use on incidence and progression rates of SIL was determined using multivariate Poisson regression to obtain incidence rate ratios (IRRs, adjusted for age, CD4 count and other potential confounders. Results: Median follow-up time was 445 days (inter-quartile range 383, 671. The crude rate of incidence of any SIL was 15.9 episodes (95% confidence limit (CL 12.7, 19.9 per 100 person-years; the crude rate of all progression of cervical dysplasia among women was 13.5 episodes (95% CL 11.3, 16.1 per 100 person-years. HAART use was associated with a robust reduction in the rate of incidence and progression of cervical lesions, adjusted IRR=0.55 (95% CL 0.37, 0.80. Sensitivity analyses confirmed this main association held for incidence and progression when they were considered separately, and that the result was not dependent on the length of HAART exposure. Conclusion: HAART use was associated with a reduction in the rate of both incidence and progression of cervical lesions among HIV-positive women.

    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 There is limited data on the prevalence of depression in HIV and AIDS patients in Sub- Saharan Africa and little resources have been allocated to address this issue. Depression affects patient adherence to treatment and predisposes patients to resistance which poses a public health threat. It also affects quality of life and productivity of patients. From August 2008 to March 2009, 731 patient adherence surveys were administered to assess disease, treatment knowledge and services received. The primary variable of interest was patients’ level of depressive symptoms score, constructed using factor analysis from five survey questions relating to: sadness, need to be alone, hopelessness and confusion and was categorized as no depressive symptoms (score 0, low depressive symptoms (score 1-2, moderate depressive symptoms (score 3-4 and high depressive symptoms (score 5-10. Majority of the patients on highly active antiretroviral therapy (HAART (59% were found to have depressive symptoms and this was more among women than men (66% vs 43%. There was some association of depressive symptoms with non-disclosure (70% of those who had not disclosed had depressive symptoms compared to 53% among those who had disclosed. There is a high prevalence of depressive symptoms among adult patients on HAART. There is need for in-depth evaluation to find out the root causes of depressive symptoms among HAART patients in AIDSRelief clinics. There is need to integrate mental health management in HIV care and treatment as well as training the existing health workers on mental health management.

    Full Text Available Background: Highly active antiretroviral therapy (HAART can reduce morbidity and mortality of HIV-infected patients. However, it depends upon adherence to medication. The objective of this study was to examine the adherence to HAART and to evaluate individual patient characteristics i.e. self-efficacy, depression level, and social support and to finally determine HAART adherence in selected regions in Indonesia.Methods: This cross-sectional study was conducted in Jakarta, Malang, Bandung, Makasar and Banda Aceh. The subject of the study was HIV-infected patients who were older than 13 years old and had taken HAART for at least a month. They were recruited consecutively then asked how many pills they had missed during the previous month. Poor adherence can be stated if the percentage of adherence rate is below 95%. HIV treatment adherence self-efficacy scale  (HIVASES, Beck Depression Inventory (BDI-II and Interpersonal Support Evaluation List (ISEL was adapted to assess self-efficacy, depression level and social support, respectively.Results: We found that 96% (n=53 of the subjects adhered to HAART. There were no associations between adherence with self-efficacy, depression level, and social support. The main cause of non-adherence in this study was ‘simply  forget’.Conclusion: Adherence to HAART was found to be high and not associated with self-efficacy, depression level and social support in some central regions in Indonesia.

    Full Text Available Objective: Introduction of new approaches for the treatment of human immunodeficiency virus (HIV infection such as anti-retroviral medicines has resulted in an increase in the life expectancy of HIV patient. Evaluating the dental health status as a part of their general health care is needed in order to improve the quality of life in these patients. The aim of this study was to compare the root and crown caries rate in HIV patients receiving highly active antiretroviral therapy (HAART with that rate in HIV patients without treatment option. Materials and Methods: This cross sectional study consisting of 100 individuals of both genders with human immunodeficiency virus were divided into two groups: i. group 1 (treatment group including 50 patients with acquired immunodeficiency syndrome (AIDS receiving HAART and ii. group 2 (control group including 50 HIV infected patients not receiving HAART. Dental examinations were done by a dentist under suitable light using periodontal probe. For each participant, numbers of decay (D, missed (M, filled (F, Decayed missed and filled teeth (DMFT, decay surface (Ds, missed surface (Ms, filled surface (Fs, Decayed missed and filled surfaces (DMFS, and tooth and root caries were recorded. Data were analyzed using Chi-square test and independent t test using SPSS 13.0, while p-value of <0.05 was considered statistically significant in all analysis. Results: The mean and standard deviation (SD of decayed, missed and filled teeth of those who were on highly active antiretroviral therapy was 6.86 ± 3.57, 6.39 ± 6.06 and 1.89 ± 1.93, respectively. There was no significant difference between these values regarding to the treatment of patients. The mean and standard deviation of DMFT, DMFS and the number of decayed root surfaces were 15.14 ± 6.09, 56.79 ± 28.56, and 4.96 ± 2.89 in patients treated by anti-retroviral medicine which were not significantly different compared to those without this treatment

    Background Morbidity and mortality of advanced human immunodeficiency virus infection (HIV) have declined in Western industrialized countries since the availability of highly active antiretroviral therapy (HAART). It is unclear if this has also happened in Hong Kong.Methods We studied a retrospective cohort of patients with advanced HIV disease in Hong Kong, China. First, the mortality of advanced HIV disease per year was calculated for the decade 1993 to 2002, both annually and according to patient observation before and after 1997. Second, the event rates were estimated for the clinical end points of acquired immune deficiency syndrome (AIDS) and death. Univariate and multivariate analyses were then performed to identify associated factors. Results The crude mortality of advanced HIV disease declined from 10.8-30.4 per 100 patients during 1993-1996, to 0.8-6.9 per 100 patients during 1997-2002. A rate ratio of 4.04 (95% CI, 2.52-6.47) was evident for those observed in 1993-1996, compared to those in 1997-2002. In a multivariate analysis where calendar period was adjusted, use of highly active antiretroviral therapy was associated with rate ratios of 0.13 (95% CI, 0.05-0.33) for death after AIDS, 0.08 (95% CI, 0.04-0.19) for AIDS after a CD4 cell count <200/μl, and 0.21 (95% CI, 0.07-0.67) for death after CD4 cell count <200/μl. In the same analysis, calendar period ceased to be a significant factor after adjustment for use of HAART.Conclusions The mortality and morbidity of advanced human immunodeficiency virus disease have declined in Hong Kong. This improved prognosis was attributable to the use of highly active antiretroviral therapy.

    Full Text Available Objective: To evaluate whether or not highly active antiretroviral therapy is associated with carotid artery stiffness in human immunodeficiency virus-positive patients in Henan Province, China. Method: Fifty human immunodeficiency virus-positive patients with at least a 5-year history of highly active antiretroviral therapy use and 50 human immunodeficiency virus-positive patients without a history of highly active antiretroviral therapy use were enrolled in this study. Carotid artery intima-media thickness and stiffness were determined by quantitative inter-media thickness and quantitative artery stiffness, respectively. Results: No statistically significant difference in carotid artery intima-media thickness and stiffness was observed between groups. A significant association between human immunodeficiency virus infection time and carotid artery stiffness was observed, but no significant association between human immunodeficiency virus infection time and intima-media thickness was found. No significant association between intima-media thickness, stiffness, and CD4+ and CD8+ T-cell counts were observed. Conclusion: The first-line highly active antiretroviral therapy currently used in China is not associated with carotid artery stiffness in human immunodeficiency virus-positive patients with good highly active antiretroviral therapy compliance. Human immunodeficiency virus may play a role in the development of atherosclerosis.

He had first been admitted 2 months previously for treatment of Pneumocystis jiroveci pneumonia. A magnetic resonance imaging scan on admission showed multiple white matter lesions involving both subcortical cerebral hemispheres and cerebellar regions, with no mass effect or surrounding edema. JC virus was detected by nested polymerase chain reaction in the cerebrospinal fluid. These findings were diagnostic of progressive multifocal leukoencephalopathy (PML. His CD4 count was 34 cells/mL, and his HIV ribonucleic acid level was 800,789 copies/mL. He was treated with a combination antiretroviral therapy. He was last reviewed in October 2011. He was fully independent socially and mentally, but he still had some residual neurologic signs with right-sided homonymous hemianopia and visual agnosia. His HIV ribonucleic acid level was undetectable, and his CD4 count was 574 cells/mm3. Although the median survival of patients with PML was poor before the antiretroviral therapy era, our patient, who is now aged 55 years, is still alive 12 years after the diagnosis. The diagnosis of PML and differential diagnosis of focal neurologic signs in HIV-positive patients are discussed in this case report.Keywords: HIV, focal neurologic signs, cerebral toxoplasmosis, primary brain lymphoma, ischaemic stroke

    Full Text Available Plasmablastic lymphoma is a rare and aggressive malignancy strongly associated with HIV infection. The refractory/relapsed disease rate is high, and the survival rate is characteristically poor. There are no satisfactory salvage regimens for relapsed cases. We successfully performed autologous stem cell transplantation using a regimen consisting of MCNU (ranimustine, etoposide, cytarabine, and melphalan in a Japanese patient with relapsed AIDS-related plasmablastic lymphoma of the oral cavity. Highly active antiretroviral therapy continued during the therapy. Therapy-related toxicity was tolerable, and a total of 40 Gy of irradiation was administered after autologous stem cell transplantation. The patient has remained in complete remission for 16 months since transplantation.

    Full Text Available Abstract Background Antiretroviral therapy (ART requires high-level (> 95% adherence. Kenya is rolling out ART access programmes and, issue of adherence to therapy is therefore imperative. However, published data on adherence to ART in Kenya is limited. This study assessed adherence to ART and identified factors responsible for non adherence in Nairobi. Methods This is a multiple facility-based cross-sectional study, where 416 patients aged over 18 years were systematically selected and interviewed using a structured questionnaire about their experience taking ART. Additional data was extracted from hospital records. Patients were grouped into adherent and non-adherent based on a composite score derived from a three questions adherence tool developed by Center for Adherence Support Evaluation (CASE. Multivariate regression model was used to determine predictors of non-adherence. Results Overall, 403 patients responded; 35% males and 65% females, 18% were non-adherent, and main (38% reason for missing therapy were being busy and forgetting. Accessing ART in a clinic within walking distance from home (OR = 2.387, CI.95 = 1.155-4.931; p = 0.019 and difficulty with dosing schedule (OR = 2.310, CI.95 = 1.211-4.408, p = 0.011 predicted non-adherence. Conclusions The study found better adherence to HAART in Nairobi compared to previous studies in Kenya. However, this can be improved further by employing fitting strategies to improve patients' ability to fit therapy in own lifestyle and cue-dose training to impact forgetfulness. Further work to determine why patients accessing therapy from ARV clinics within walking distance from their residence did not adhere is recommended.

    Full Text Available OBJECTIVE: The study investigated markers of inflammation and endothelial activation in HIV infected patients after 12 years of successful combination antiretroviral treatment (cART. METHODS: Inflammation and endothelial activation were assessed by measuring levels of immunoglobulins, β2-microglobulin, interleukin (IL 8, tumor necrosis factor α (TNFα, vascular cell adhesion molecule-1 (sVCAM-1, intercellular adhesion molecule-1 (sICAM-1, sE-Selectin, and sP-Selectin. RESULTS: HIV infected patients had higher levels of β2-microglobulin, IL-8, TNFα, and sICAM-1 than uninfected controls, and HIV infected patients lacked correlation between platelet counts and sP-Selectin levels found in uninfected controls. CONCLUSION: Discrete signs of systemic and vascular inflammation persist even after very long term cART.

    High blood levels of the soluble urokinase receptor (suPAR) strongly predict increased mortality in human immunodeficiency virus-1 (HIV-1)-infected patients. This study investigated the plasma concentration of suPAR in 29 treatment-naive HIV-1-infected patients during 5 years treatment with highly...... active antiretroviral therapy (HAART). Plasma suPAR decreased after introducing HAART, most pronounced during the first treatment year. The change in plasma suPAR was independent of changes in viral replication and CD4+ cells but it was strongly correlated with plasma levels of the soluble TNF receptor...... II. Compared with healthy individuals, plasma suPAR and sTN-FrII was increased in untreated patients. After initiating HAART, plasma sTNFrII remained increased whereas plasma suPAR decreased to a level comparable with healthy individuals. The present data indicate that the circulating suPAR level is...

    Full Text Available INTRODUCTION: HIV-infected children and adolescents treated with highly active antiretroviral therapy (HAART regimens that include a protease inhibitor (PI can show significant improvements in clinical outcomes, nutritional status and quality of life. The study aimed to report nutritional and metabolic alterations for pediatric patients continuously exposed to HAART and for healthy controls for up to 1 year. METHODS: Clinical, anthropometric, lipid profile and food intake data were collected prospectively over approximately 12-months for each patient. RESULTS: Fifty-one individuals were studied, of these, 16 were healthy. After 12 months follow-up, HIV-positive individuals remained below the healthy control group parameters. No change was observed concerning food intake. Triglyceride serum levels were higher in patients using protease inhibitor at the onset of the study [PI groups: 114 (43 - 336, and 136 (63 - 271 versus control group: 54.5 (20 - 162; p = 0.003], but after twelve months follow-up, only the group using protease inhibitor for up to two months presented higher values [140 (73 - 273 versus 67.5 (33 - 117; p = 0.004]. HDL-cholesterol was lower in HIV-positive individuals [HIV-positive groups: 36 (27 - 58 and 36 (23 - 43; control 49.5 (34 - 69; p = 0.004]. CONCLUSIONS: HIV-infected children and adolescents treated with highly active antiretroviral therapy showed compromised nutritional parameters compared to a paired healthy control group. Individuals using protease inhibitor presented worse triglyceride serum levels compared to their healthy counterparts.

    Background At the end of 2005, 650 000 people lived with human immunodeficiency virus type-1 (HIV-1) in (HAART) supported by the "China CARES" program but the immune responses of HAART were seldom reported. This study investigated the effect of HAART on the activation and coreceptor expression of T lymphocytes in Chinese HIV/AIDS patients and evaluated its effect on immune reconstitution.Methods Seventeen HIV/AIDS patients were enrolled and three-color-flow cytometry was used to detect the activation of HLA-DR CD38 and the coreceptor CCR5, CXCR4 expression on T lymphocytes in whole blood samples taken from the patients before and after 3- or 6-month HAART.Results The activation percents of CD4+, CD8+ T lymphocytes were significantly higher before therapy than the normal controls (HLA-DR/CD4: 40.47± 18.85 vs 11.54±4.10; CD38/CD4: 81.34± 10.86 vs 53.34± 11.44;HLA-DR/CD8:63.94±12.71 vs 25.67±9.18; CD38/CD8:86.56±11.41 vs 58.84±6.16, all P<0.01). After 6-month combined antiretroviral treatment, the activation of T lymphocytes in HIV/AIDS patients was significantly decreased (HLA-DR/CD4:28.31 ± 13.48; CD38/CD4:69.88 ± 12.64; HLA-DR/CD8: 46.56±18.64;CD38/CD8: 70.17± 14.54, all P<0.01 compared with the pre-treatment values). Before the treatment, CCR5 expression on CD8+ T lymphocytes was up-regulated while CXCR4 expression on CD8+ T lymphocytes downregulated in HIV/AIDS patients compared with the normal controls (CD8/CCR5:70.9 1± 10.03 vs 52.70 ±7.68; CD8/CXCR4: 24.14± 11.08 vs 50.05± 11.68, all P<0.01). After 6-month HAART, CCR5 expression on CD8+ T lymphocytes significantly decreased (56.35±12.96, P<0.01), while CXCR4 expression on CD8+ T lymphocytes increased (36.95±9.96, P<0.05) compared with the pre-treatment and the normal controls. A significant statistical relationship was observed between the expression of activation markers, CCR5 and the CD4+ T lymphocyte counts after HAART (P<0.05).Conclusions Reduced activation of T lymphocytes

    Full Text Available Background: With widespread use of antiretroviral therapy (ART and prolonged survival of HIV-infected children, toxicities like lipodystrophy are becoming more evident. Little is known about lipodystrophy in children in Uganda yet there is increased use of ART. The aim of this study was to determine the prevalence and factors associated with fat redistribution and metabolic abnormalities among HIV-infected children on highly active antiretroviral therapy (HAART in Uganda. Methods: A cross-sectional study of 364 HIV positive children aged between 2 and 18 years on ART were enrolled after consent and assent as appropriate. Sociodemographic, clinical and immunological data were collected and recorded in a questionnaire. Fat redistribution was assessed clinically for physical findings of lipohypertrophy and lipoatrophy. A fasting blood sample was taken for lipid profile and blood glucose analysis. Lipodystrophy was defined as presence of abnormal fat redistribution or metabolic abnormalities or both. The proportion of children with fat redistribution and metabolic abnormalities was calculated. We conducted multivariate analysis for factors associated with lipodystrophy among children with lipodystrophic features and those without. Results: The median age of the participants was eight years (range 2 to 18, with 43% of these aged ≥10 years and a male to female ratio of 1.1:1. Majority (65% had advanced HIV (WHO Stage III/IV at ART initiation with a mean duration on ART of 3.8 years (±1.2. The prevalence of fat redistribution and hyperlipidemia was 27.0% and 34.0%, respectively. None of the children had hyperglycaemia. Among the children with hyperlipidemia, 16.8% exhibited hypercholesterolemia and 83% had hypertriglyceridemia. Only 29% of children with fat redistribution had hyperlipidemia. We found significant association between fat redistribution and Tanner stages 2 to 5 OR=2.3 (95%CI 1.3 to 3.8, age≥5 years OR=3.9 (95%CI 1.5 to 9.9 and d4T

    Full Text Available UNLABELLED: Persistent immune activation plays a central role in driving Human Immunodeficiency Virus (HIV disease progression. Whether CD4+CD25+ regulatory T cells (Tregs are harmful by suppressing HIV-specific immune responses and/or beneficial through a decrease in immune activation remains debatable. We analysed the relationship between proportion and number of regulatory T cells (Tregs and immune activation in HIV-infected patients interrupting an effective antiretroviral therapy (ART. Twenty-five patients were included in a substudy of a prospective multicenter trial of treatment interruption (TI (ANRS 116. Proportions and numbers of Tregs and the proportion of activated CD4 and CD8 T cells were assessed at baseline and month 12 (M12 of TI. Specific anti-HIV CD4 and CD8 responses were investigated at baseline and M12. Non parametric univariate analyses and multivariate linear regression models were conducted. At baseline, the proportion of Tregs negatively correlated with the proportion of HLA-DR+CD8+T cells (r=-0.519. Following TI, the proportion of Tregs increased from 6.3% to 7.2% (p=0.029; absolute numbers of Tregs decreased. The increase in the proportion of HLA-DR+CD38+CD8+T cells was significantly related to the increase in proportion of Tregs (p=0.031. At M12, the proportion of Tregs did not negatively correlate with CD8 T-cell activation. Nevertheless, Tregs retain a suppressive function since depletion of Treg-containing CD4+CD25+ cells led to an increase in lymphoproliferative responses in most patients studied. Our data suggest that Tregs are efficient in controlling residual immune activation in patients with ART-mediated viral suppression. However, the insufficient increase in the proportion and/or the decrease in the absolute number of Tregs result in a failure to control immune activation following TI.

    The long-term kinetics of T cell production following highly active antiretroviral therapy (HAART) were investigated in blood and lymph node in a group of HIV-infected subjects at early stage of established infection and prospectively studied for 72 wk. Before HAART, CD4 and CD8 T cell turnover was increased. However, the total number of proliferating CD4+ T lymphocytes, i.e., CD4+Ki67+ T lymphocytes, was not significantly different in HIV-infected (n = 73) and HIV-negative (n = 15) subjects, whereas proliferating CD8+Ki67+ T lymphocytes were significantly higher in HIV-infected subjects. After HAART, the total body number of proliferating CD4+Ki67+ T lymphocytes increased over time and was associated with an increase of both naive and memory CD4+ T cells. The maximal increase (2-fold) was observed at week 36, whereas at week 72 the number of proliferating CD4+ T cells dropped to baseline levels, i.e., before HAART. The kinetics of the fraction of proliferating CD4 and CD8 T cells were significantly correlated with the changes in the total body number of these T cell subsets. These results demonstrate a direct relationship between ex vivo measures of T cell production and quantitative changes in total body T lymphocyte populations. This study provides advances in the delineation of the kinetics of T cell production in HIV infection in the presence and/or in the absence of HAART. PMID:10805798

    Posterior reversible encephalopathy (PRES) is a condition characterized by T2 and FLAIR hyperintensities in magnetic resonance imaging (MRI) studies, localized preferentially in the occipital-parietal white matter regions. Pathological MRI images located in midbrain, pons, medulla and spinal cord, that could be asymptomatic, were recently included in this entity. These images are interpreted as vasogenic edema, which is caused by arterial hypertension or eclampsia, neurotoxicity related to immunosuppressive agents or chemotherapy, among other causes. We report a 25 years old asymptomatic male with AIDS, with normal blood pressure who after initiating highly active antiretroviral therapy (HAART) reported vertigo. The MRI showed a central pontine T2 hyperintensity with diffusion restriction, which was interpreted as a central pontine myelinolysis (CPM), but the lack of motor symptoms made improbable a real demyelination of the pons. The follow-up MRI revealed complete regression of the images. To our knowledge, this case could be the second report of a reversible leucopathy of the pons in a patient with AIDS, were the MRI images also simulated a CPM. This report extends the knowledge around the variability of the pathogenic interpretation of CPM images and their association with HAART. PMID:27552021

    Patients with human immunodeficiency virus type 1 (HIV-1) infection are at high risk of developing Epstein-Barr virus (EBV)-associated lymphoma. However, little is known of the EBV DNA loads in patients receiving highly active antiretroviral therapy (HAART). Using a real-time quantitative polymerase chain reaction assay, we demonstrated that significantly more HIV-1-infected patients receiving HAART than HIV-1-uninfected volunteers had detectable EBV DNA in blood (57 [81%] of 70 vs. 11 [16%] of 68 patients; P=.001) and saliva (55 [79%] of 68 vs. 37 [54%] of 68 patients; P=.002). The mean EBV loads in blood and saliva samples were also higher in HIV-1-infected patients than in HIV-1-uninfected volunteers (P=.001). The frequency of EBV detection in blood was associated with lower CD4+ cell counts (P=.03) among HIV-1-infected individuals, although no differences were observed in the EBV DNA loads in blood or saliva samples in the HIV-1-infected group. Additional studies are needed to determine whether EBV-specific CD4+ and CD8+ cells play a role in the pathogenesis of EBV in HIV-1-infected patients receiving HAART.

    The effects of highly active antiretroviral therapy (HAART) to patients with AIDS in Hubei province of China were investigated in order to provide scientific evidence to reinforce the management of HAART. Self-made questionnaires and descriptive method of epidemiology were used to collect and describe the changes of clinical symptoms, HIV RNA concentration, and immune function of patients with AIDS. After HAART, the effective rate of fever, cough, diarrhea, lymphadenectasis, weight loss,tetter, debility and fungous infection was 92.4%, 90.85%, 92.91%, 90.73%, 93.69%, 89.04%, 92.34%,and 83.1%, respectively. Of 117 patients with detected HIV RNA concentration, 41.03% had declined over 0.5 log, and 52.99% less than 0.5 log. CD4+T cell count was obviously increased: the average number after HAART for 3 or 6 months was 237/μL (26-755/μL) and 239/μL (17-833/μL), respectively.HAART can improve AIDS patients' clinical symptoms, reduce HIV RNA concentration, and maintain immune function. It is very important for the effectiveness of HAART to raise clinical adherence of pa-tients with AIDS and have a persistent surveillance.

    Background Highly active antiretroviral therapy (HAART) roduces profound suppression of HIV replication, substantial increase in CD4+ T cells, and partial reconstitution of the immune system. However, the numbers of subjects were small in previous Chinese studies. This study evaluated the efficacy and side effects of HAART in Chinese advanced AIDS patients.Methods One hundred and three antiretroviral drug naive AIDS patients were enrolled in this study and were divided into two groups by their baseline CD4+ count: <100 cells/ μl or ≥ 100 cells/μl. Clinical, virological and immunological outcomes were monitored at baseline and at 1, 3, 6, 9 and 12 months during the course of treatment with HAART.Results One patient died and another was lost from the follow-up. For the remaining 101 HIV/AIDS patients at the 12th month during the HAART, the plasma viral load (VL) was reduced to (3.2±0.7) lg copies/ml, the CD4+ count increased to (168±51) cells/μl [among which the naive phenotype (CD45RA+CD62L+) increased to (49±27) cells/μl and the memory phenotype (CD45RA ̄) increased to (119±55) cells/μl], and the percentage of CD4+CD28+ cells increased. At the same time, there was a significant reduction of CD8+ T cell activation. In the 69 patients with the baseline CD4+ count <100 cells/μl, 37 had a VL <50 copies/ml; while in the 34 patients with the baseline CD4+ count ≥ 100 cells/μl, 25 had a VL <50 copies/ml, the difference between the two groups was statistically significant. The CD4+ T cell count showed a two-phase increase during HAART and a significant positive correlation was shown between the change of CD4+ count and plasma VL. Over 12 months of HAART,10 patients had gastrointestinal side effects, 13 peripheral neuritis, 7 hepatic lesions, 8 hematological side effects,8 skin rashes, 10 lipodystrophy and 1 renal calculus.Conclusions Immune reconstitution as well as the significantly improved clinical outcomes is observed in Chinese advanced AIDS

    Lipodystrophy is a common complication in HIV-infected patients taking highly active antiretroviral therapy. Its early diagnosis is crucial for timely modification of antiretroviral therapy. We hypothesize that mitochondrial DNA in plasma may be a potential marker of LD in HIV-infected individuals. In this study, we compared plasma mitochondrial DNA levels in HIV-infected individuals and non-HIV-infected individuals to investigate its potential diagnostic value. Total plasma DNA was extracted from 67 HIV-infected patients at baseline and 12, 24 and 30 months after initiating antiretroviral therapy. Real-time quantitative PCR was used to determine the mitochondrial DNA levels in plasma. Lipodystrophy was defined by the physician-assessed presence of lipoatrophy or lipohypertrophy in one or more body regions. The mitochondrial DNA levels in plasma were significantly higher at baseline in HIV-infected individuals than in non-HIV-infected individuals (pmitochondrial DNA levels in lipodystrophy patients were significantly higher compared to those without lipodystrophy at month 24 (pmitochondrial DNA level (with cut-off value mitochondrial DNA levels may help to guide therapy selection with regards to HIV lipodystrophy risk.

    Full Text Available Amid numerous complications that plague the health and quality of life of people living with HIV, neurocognitive and psychiatric illnesses pose unique challenges. While there remains uncertainty with respect to the pathophysiology surrounding these disorders, their adverse implications are increasingly recognized. Left undetected, they have the potential to significantly impact patient well being, adherence to antiretroviral treatment and overall health outcomes. As such, early identification of HIV-associated neurocognitive disorders (HAND and psychiatric illnesses will be paramount in the proactive management of affected patients. The present review focuses on strategies to ensure optimal screening and detection of HAND, depression and substance abuse in routine practice. For each topic, currently available screening methods are discussed. These include identification of risk factors, recognition of relevant symptomatology and an update on validated screening tools that can be efficiently implemented in the clinical setting. Specifically addressed in the present review are the International HIV Dementia Scale, a novel screening equation and algorithm for HAND, as well as brief, validated, verbal questionnaires for detection of depression and substance abuse. Adequate understanding and usage of these screening mechanisms can ensure effective use of resources by distinguishing patients who require referral for more extensive diagnostic procedures from those who likely do not.

    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

    Full Text Available Abstract Background Few studies address the use of paediatric highly active antiretroviral therapy (HAART in Africa. Methods We performed a retrospective cohort study to investigate preliminary outcomes of all children eligible for HAART at Sinikithemba HIV/AIDS clinic in KwaZulu-Natal, South Africa. Immunologic, virologic, clinical, mortality, primary caregiver, and psychosocial variables were collected and analyzed. Results From August 31, 2003 until October 31, 2005, 151 children initiated HAART. The median age at HAART initiation was 5.7 years (range 0.3–15.4. Median follow-up time of the cohort after HAART initiation was 8 months (IQR 3.5–13.5. The median change in CD4% from baseline (p 95%adherence. Seventeen patients (11.3% had a regimen change; two (1.3% were due to antiretroviral toxicity. The Kaplan-Meier one year survival estimate was 90.9% (95%confidence interval (CI 84.8–94.6. Thirteen children died during follow-up (8.6%, one changed service provider, and no children were lost to follow-up. All 13 deaths occurred in children with advanced HIV disease within 5 months of treatment initiation. In multivariate analysis of baseline variables against mortality using Cox proportional-hazards model, chronic gastroenteritis was associated with death [hazard ratio (HR, 12.34; 95%CI, 1.27–119.71 and an HIV-positive primary caregiver was found to be protective against mortality [HR, 0.12; 95%CI, 0.02–0.88. Age, orphanhood, baseline CD4%, and hemoglobin were not predicators of mortality in our cohort. Fifty-two percent of the cohort had at least one HIV-positive primary caregiver, and 38.4% had at least one primary caregiver also on HAART at Sinikithemba clinic. Conclusion This report suggests that paediatric HAART can be effective despite the challenges of a resource-limited setting.

    Adherence to HIV medication regimens is a function of multiple dimensions including psychological functioning, social support, adherence self-efficacy and optimism regarding treatment. Active substance use can also negatively affect adherence. An understanding of the nature of the associations among the correlates of adherence can better inform the design of interventions to improve adherence. This study developed an exploratory path model of schedule adherence using data from a sample 130 African-American HIV-positive crack cocaine users on highly active antiretroviral therapy (ART). This model was based on the Transactional Model of Stress and Coping developed by Lazarus and Folkman. Following the theory, the effects of psychological distress on schedule adherence were mediated by patients' relationship with their doctor and optimism towards antiretroviral treatment. Adherence was also associated with patients' self-efficacy regarding their medical regimen which, in turn, was associated with their social support.

    Liver mitochondrial toxicity is a concern, particularly in HIV/hepatitis C virus (HCV) coinfection. Liver biopsies from HIV/HCV co-infected patients, 14 ON-highly active antiretroviral therapy (HAART) and nine OFF-HAART, were assessed by electron microscopy quantitative morphometric analyses. Hepatocytes tended to be larger ON-HAART than OFF-HAART (P = 0.05), but mitochondrial volume, cristae density, lipid volume, mitochondrial DNA and RNA levels were similar. We found no evidence of increased mitochondrial toxicity in individuals currently on HAART, suggesting that concomitant HAART should not delay HCV therapy. PMID:18525271

    Full Text Available Abstract Background The efficacy of highly active antiretroviral therapy (HAART determined by simultaneous monitoring over 100 cell-surface antigens overtime has not been attempted. We used an antibody microarray to analyze changes in the expression of 135 different cell-surface antigens overtime on PBMC from HIV+ patients on HAART. Two groups were chosen, one (n = 6 achieved sustainable response by maintaining below detectable plasma viremia and the other (n = 6 responded intermittently. Blood samples were collected over an average of 3 years and 5–8 time points were selected for microarray assay and statistical analysis. Results Significant trends over time were observed for the expression of 7 cell surface antigens (CD2, CD3epsilon, CD5, CD95, CD36, CD27 and CD28 for combined patient groups. Between groups, expression levels of 10 cell surface antigens (CD11a, CD29, CD38, CD45RO, CD52, CD56, CD57, CD62E, CD64 and CD33 were found to be differential. Expression levels of CD9, CD11a, CD27, CD28 and CD52, CD44, CD49d, CD49e, CD11c strongly correlated with CD4+ and CD8+ T cell counts, respectively. Conclusion Our findings not only detected markers that may have potential prognostic/diagnostic values in evaluating HAART efficacy, but also showed how density of cell surface antigens could be efficiently exploited in an array-like manner in relation to HAART and HIV-infection. The antigens identified in this study should be further investigated by other methods such as flow cytometry for confirmation as biological analysis of these antigens may help further clarify their role during HAART and HIV infection.

  12. Immune reconstitution inflammatory syndrome in HIV-infected patients with mycobacterial infections starting highly active anti-retroviral therapy

    International Nuclear Information System (INIS)

    AIM: To describe the radiological appearances of immune reconstitution inflammatory syndrome (IRIS) in human immunodeficiency virus (HIV)-infected patients with mycobacterial infections starting highly active anti-retroviral therapy (HAART). MATERIALS AND METHODS: Five consecutive HIV infected patients with IRIS due to mycobacterial infection were studied. Intercurrent infection and poor drug compliance were excluded as causes of presentation. The chest radiological appearances at the time of starting HAART and at the time of diagnosis of IRIS were compared. RESULTS: In these five patients there was clinical and radiological deterioration, occurring between 10 days and 7 months after starting HAART, leading to unmasking of previously undiagnosed mycobacterial infection or to worsening of mycobacterial disease. All five patients had HAART-induced increases in CD4+ T lymphocyte counts and reductions in peripheral blood HIV 'viral load'. Chest radiographic abnormalities due to IRIS included marked mediastinal lymphadenopathy in three patients--severe enough to produce tracheal compression in two patients (one of whom had stridor)--and was associated with new pulmonary infiltrates in two patients. The other two patients had new infiltrates, which in one patient was associated with a pleural effusion. CONCLUSION: These cases illustrate the diverse chest radiographic appearances of IRIS occurring after HAART in patients with mycobacterial and HIV co-infection. Marked mediastinal lymphadenopathy occurred in three of these five patients (with associated tracheal narrowing in two patients); four patients developed pulmonary infiltrates and one had an effusion. The cases further highlight that the onset of IRIS may be delayed for several months after HAART is started

    Full Text Available Opportunistic and intestinal parasite infections are common health problem among HIV/AIDS patients. Early detection and treatment of these parasites are important to improve the quality of life of this category of patients. The occurrence of intestinal parasites among 400 patients on highly active anti-retroviral drug therapy (HAART aged 11-60 years was investigated. Standard parasitological techniques like direct microscopy, formol ether concentration and modified Ziehl- Neelsen staining techniques were used to analyze the stool samples. Intestinal parasite infections were positive in 116 (29% of the subjects on HAART while control subjects had 12 (12% and the difference was statistically significant (P<0.05. Subjects in the age group 21-30 years had the highest infection rate 54 (35.1%. There was no statistically significant difference in infection according to age (P>0.05. Females 76 (32.5% had a higher prevalence rate than males 40 (24.1%. But there was no statistically significant difference in infection according to gender (P<0.05. Patients with CD4 count of less than 200 cells/mm3 were observed to be more infected than those with CD4 count of more than 200 cells/mm3. There was a strong positive correlation (r=0.94 between CD4 count and the occurrence of intestinal parasite infection. Protozoan parasites 84 (21.0% accounted for a higher prevalence rate than helminthic parasites 32 (8.0%. These findings has revealed a high prevalence of intestinal parasite infection among patients on HAART thus the routine screening of stool samples from these category of patients for intestinal parasites is advocated for effective management of the disease.

    Full Text Available These guidelines are intended as an update to those published in the Southern African Journal of HIV Medicine in January 2008. Since the release of the previous guidelines, the scale-up of antiretroviral therapy (ART in Southern Africa has continued to grow. Cohort studies from the region show excellent clinical outcomes; however, ART is still being started late (in advanced disease, resulting in relatively high early mortality rates. New data on antiretroviral (ARV tolerability in the region and several new ARV drugs have become available. Although currently few in number, some patients in the region are failing protease inhibitor (PI-based second-line regimens. To address this, guidelines on third-line (or ‘salvage’ therapy have been expanded.

    We estimated the AIDS survival by neighborhood socioeconomic status before (1993-1995) and after (1996-1997) the introduction of highly active antiretroviral therapy in Rome, Italy, in a retrospective cohort of persons with AIDS followed through July 31, 1998. Participants included 1,474 persons with AIDS residing in Rome who were diagnosed in 1993-1997. We calculated hazard ratios (HRs) of death for two diagnostic periods (before and after highly active antiretroviral therapy was introduced) by neighborhood socioeconomic status categorized into four levels (level I = highest socioeconomic status), using the Cox model and adjusting for gender, age, intravenous drug use, CD4 cell count at diagnosis, AIDS-defining disease, and hospital of diagnosis. Thirty-four per cent of persons with AIDS (N = 503) had survived as of mid-1998. For persons with AIDS diagnosed in 1993-1995, we found little difference in the risk of death by neighborhood socioeconomic status. For 1996-1997, the risk of death was greater for persons with lower neighborhood socioeconomic status, especially for levels III and IV [HR = 2.81 (95% confidence interval = 1.38-5.76), and HR = 2.55 (95% confidence interval = 1.27-5.14), respectively, compared with level I]. Stratified analyses showed that the greatest difference was found for women and drug users. In conclusion, even in a country with universal health coverage that provides therapy at no cost, differences in survival of persons with AIDS have emerged by neighborhood socioeconomic status since highly active antiretroviral therapy was introduced. Inequalities in health-care access or in medical management, or poor adherence to treatment, could explain the observed heterogeneity.

    Identifying the immunologic and virologic consequences of discontinuing antiretroviral therapy in HIV-infected patients is of major importance in developing long-term treatment strategies for patients with HIV-1 infection. We designed a trial to characterize these parameters after interruption of highly active antiretroviral therapy (HAART) in patients who had maintained prolonged viral suppression on antiretroviral drugs. Eighteen patients with CD4+ T cell counts ≥ 350 cells/μl and viral load below the limits of detection for ≥1 year while on HAART were enrolled prospectively in a trial in which HAART was discontinued. Twelve of these patients had received prior IL-2 therapy and had low frequencies of resting, latently infected CD4 cells. Viral load relapse to >50 copies/ml occurred in all 18 patients independent of prior IL-2 treatment, beginning most commonly during weeks 2–3 after cessation of HAART. The mean relapse rate constant was 0.45 (0.20 log10 copies) day−1, which was very similar to the mean viral clearance rate constant after drug resumption of 0.35 (0.15 log10 copies) day−1 (P = 0.28). One patient experienced a relapse delay to week 7. All patients except one experienced a relapse burden to >5,000 RNA copies/ml. Ex vivo labeling with BrdUrd showed that CD4 and CD8 cell turnover increased after withdrawal of HAART and correlated with viral load whereas lymphocyte turnover decreased after reinitiation of drug treatment. Virologic relapse occurs rapidly in patients who discontinue suppressive drug therapy, even in patients with a markedly diminished pool of resting, latently infected CD4+ T cells. PMID:10611346

    Abstract As cellular reservoirs, CD16+ monocyte subsets play important roles in the progression of HIV infection. Previous studies have shown that highly active antiretroviral therapy (HAART) reduced the percentages of CD14highCD16+ monocyte subsets, but did not recover the percentages of CD14lowCD16+ subsets. Eighty-four chronic HIV-infected, HAART-naïve individuals and 55 HIV-negative subjects (31 without hyperlipidemia and 24 with hypertriglyceridemia) were enrolled. Plasma HIV-1 RNA level...

    Full Text Available Knowledge of mortality trends and predictors among HIV-positive patients in the era of highly active antiretroviral therapy (HAART in resource poor settings is still limited. The aim of this study was to describe trends and predictors of mortality among HIV-positive patients in the era of HAART in Uganda. Data from 2004 to 2013 for adult HIV-positive patients (≥15 years obtaining care and treatment from the AIDS Support Organization in Uganda were reviewed for mortality. Descriptive statistics were analyzed by frequencies and cross tabulations. Calendar period was used as a proxy measure for HAART exposure and a time plot of the proportion of HIV-positive patients reporting dead per year was used to describe the trends. Logistic regression was used to determine the predictors of mortality at bivariate and multivariate levels, respectively. We included in the analysis 95,857 HIV positive patients; 64% were female with median age of 33 years (interquartile range 27-40. Of these 36,133 (38% were initiated on ART and a total of 4279 (4.5% died; 19.5% (835/4279 of those who died had an opportunistic infection. Overall, mortality first increased between 2004 and 2006 and thereafter substantially declined (X2trend=211.9, P<0.001. Mortality was relatively higher in Eastern Uganda compared to other geographical areas. Male gender, older age (>45 years, being from Eastern or Northern Uganda, having none or primary education, being unemployed, advanced immunodeficiency (CD4 count <100 cell/μL or WHO stage III or IV and underweight (<45 kg weight at HAART initiation and calendar period 2004-2008 were significant predictors of mortality (P<0.001. Overall, the expanding coverage of HAART is associated with a declining trend in mortality among HIV positive patients in Uganda. However, mortality trends differed significantly by geographical area and men remain potentially at higher risk of death probably because of delayed initiation on ART. There is urgent

    Purpose of review The present review will highlight some of the recent findings regarding the capacity of HIV-1 to replicate during antiretroviral therapy (ART). Recent findings Although ART is highly effective at inhibiting HIV replication, it is not curative. Several mechanisms contribute to HIV persistence during ART, including HIV latency, immune dysfunction, and perhaps persistent low-level spread of the virus to uninfected cells (replication). The success in curing HIV will depend on efficiently targeting these three aspects. The degree to which HIV replicates during ART remains controversial. Most studies have failed to find any evidence of HIV evolution in blood, even with samples collected over many years, although a recent very intensive study of three individuals suggested that the virus population does shift, at least during the first few months of therapy. Stronger but still not definitive evidence for replication comes from a series of studies in which standard regimens were intensified with an integration inhibitor, resulting in changes in episomal DNA (blood) and cell-associated RNA (tissue). Limited drug penetration within tissues and the presence of immune sanctuaries have been argued as potential mechanisms allowing HIV to spread during ART. Mathematical models suggest that HIV replication and evolution is possible even without the selection of fully drug-resistant variants. As persistent HIV replication could have clinical consequences and might limit the efficacy of curative interventions, determining if HIV replicates during ART and why, should remain a key focus of the HIV research community. Summary Residual viral replication likely persists in lymphoid tissues, at least in a subset of individuals. Abnormal levels of immune activation might contribute to sustain virus replication.

Four focus group discussions were held with a convenience sample of 40 married men.Results: Lack of disclosure of a positive HIV diagnosis to the partner and stigmatization of persons with HIV were two major obstacles for women in accessing HAART. In addition, men felt that their low knowledge of HAART and their low HIV testing rate also constituted important barriers to these women taking treatment. Men complained that they were not sufficiently involved in the reproductive care of women and that couples’ counseling could be a step towards addressing this problem.Conclusion: Barriers to HAART experienced by pregnant/postnatal women need to be addressed in order to improve their uptake of treatment, increase their low treatment coverage, improve their survival, and at the same time dramatically reduce HIV transmission from mother to child.Keywords: men, highly active antiretroviral therapy, pregnant women, Uganda

    Full Text Available Clinical depression is a highly debilitating illness, which is often under-diagnosed and negatively impacts on the quality of life of its sufferers. When it co-exists with other medical conditions, its effect is even more incapacitating. Undiagnosed depression in the context of HIV infection leads to accelerated decline in CD4+ cell counts with concomitant increase in the viral load and poor adherence to the antiretroviral medications which lead to viral mutation and the evolution of resistant strains. This study examined the prevalence of depression, its correlates and the frequency of the diagnosis of the condition among HIV+ subjects on highly active antiretroviral therapy (HAART by the internists and general physicians at the University of Maiduguri Teaching Hospital in Northeastern Nigeria. Three hundred and fifty representative samples of HIV+ adults on HAART were drawn from the Antiretroviral Therapy Clinic of the Institution. Diagnosis of depression was made using the International Classification of Diseases-10 criteria based on Composite International Diagnostic Interview generated data. Socio-demographic and clinical variables were also analyzed for their correlation with depression in the subjects. About 20% of the respondents were diagnosed with clinical depression and no diagnosis of the condition was hitherto entertained in all the respondents. The independent determinants of depression in the participants were: female gender [odds ratio (OR=3.87 (95% confidence interval, CI: 2.089-7.183], past history of psychiatric illness [OR=43.81 (95% CI: 9.731-197.30] and family history of psychiatric illness in first-degree relatives of the subjects [OR=14.364 (95% CI=5.327- 38.729]. Depression is a relatively common psychiatric condition among adults on HAART, there is therefore the need for routine screening of this condition among HIV+ subjects in order to optimize patient care and improve clinical outcomes.

    The introduction of Highly Active Antiretroviral Therapy (HAART) into clinical practice has dramatically changed the natural approach of HIV-related cancers. Several studies have shown that intensive antiblastic chemotherapy (AC) is feasible in HIV-infected patients with cancer, and that the outcome is similar to that of HIV-negative patients receiving the same AC regimens. However, the concomitant use of HAART and AC can result in drug accumulation or possible toxicity with consequent decreased efficacy of one or both classes of drugs. In fact, many AC agents are preferentially metabolized by CYP450 and drug-drug interactions (DDIs) with HAART are common. Therefore, it is important that HIV patients with cancer in HAART receiving AC treatment at the same time receive an individualized cancer management plan based on their liver and renal functions, their level of bone marrow suppression, their mitochondrial dysfunction, and their genotype profile. The rationale of this review is to summarize the existing data on the impact of HAART on the clinical management of cancer patients with HIV/AIDS and DDIs between antiretrovirals and AC. In addition, in order to maximize the efficacy of antiblastic therapy and minimize the risk of drug-drug interaction, a useful list of pharmacogenomic markers is provided.

    Active injection drug users (IDUs) are at high risk of unsuccessful highly active antiretroviral therapy (HAART). We sought to identify baseline factors differentiating IDUs' treatment success versus treatment failure over time among those taking HAART. Interventions for Seropositive Injectors-Research and Evaluation (INSPIRE) study participants were assessed at baseline and at 6- and 12-month follow-ups. Multinominal regression determined baseline predictors of achieving or maintaining viral suppression relative to maintaining detectable viral loads over 12 months. Of 199 participants who were retained and remained on HAART, 133 (67%) had viral load change patterns included in the analysis. At follow-up, 66% maintained detectable viral loads and 15% achieved and 19% maintained viral suppression. Results indicated that those having informal care (instrumental or emotional support) were 4.6 times more likely to achieve or maintain viral suppression relative to experiencing treatment failure. Those who maintained viral suppression were 3.5 times less likely to live alone or to report social discomfort in taking HAART. Study results underscore the importance of microsocial factors of social network support, social isolation, and social stigma for successful HAART outcomes among IDUs. The findings suggest that adherence interventions for IDUs should promote existing informal HIV caregiving, living with supportive others, and positive medication-taking norms among social networks.

    Introduction: Human immunodeficiency virus (HIV) infection gradually destroys the body's immune system, which makes it harder for the body to fight infections. HIV infection causes a quantitative and qualitative depletion of CD4 lymphocyte count, which increases the risk of opportunistic infections. Thus, CD4 count is one of the key factors in determining both the urgency of highly active antiretroviral therapy (HAART) initiation and the need of prophylaxis for opportunistic infections. Aim: This study aims to evaluate the prevalence and variations in the oral manifestations of HIV/acquired immune deficiency syndrome patients on HAART therapy in urban population and their association with CD4 count. Materials and Methods: A study was conducted by screening eighty patients who were HIV positive in an urban location. Both adult and pediatric patients were screened for oral manifestations and simultaneously CD4 count was also evaluated. Patients with HIV infection for variable time period who are under HAART were considered. Statistical Analysis: Measures of central tendency were used to analyse the data. Results: HIV infection destroys the immune system of an individual, making the patient susceptible to various infections and malignancies. With the advent of antiretroviral therapy, the scenario has changed drastically. We have observed that patients with CD4 counts between 164 and 1286 show relatively few oral manifestations. Long-term HAART therapy causes pigmentation, xerostomia and angular cheilitis but is taken up quite well by the patients. Conclusion: In this study, eighty patients with HAART from urban population showed very minimal oral findings because of good accessibility for treatment and awareness about HIV infections. The patients who were on long-standing HAART treatment also showed minimal oral manifestation such as pigmentation and xerostomia. Hence, we conclude that recognition, significance and treatment of these lesions in patients with HIV

    We conducted a case-controlled study of the associations of CCR5-Δ32 heterozygosity with human immunodeficiency virus type 1 (HIV-1) reservoir size, lymphocyte activation, and CCR5 expression in 114 CCR5(Δ32/WT) and 177 wild-type CCR5 AIDS Clinical Trials Group participants receiving suppressive antiretroviral therapy. Overall, no significant differences were found between groups for any of these parameters. However, higher levels of CCR5 expression correlated with lower amounts of cell-associated HIV-1 RNA. The relationship between CCR5-Δ32 heterozygosity, CCR5 expression, and markers of HIV-1 persistence is likely to be complex and may be influenced by factors such as the duration of ART.

    2015-04-01

    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.

This qualitative study used focus groups to explore the views and experiences of HIV patients on HAART with adherence reminders, especially the text message (SMS [short message service]. The ethnographic data obtained were used to design a clinical trial to assess the effect of motivational text messages versus usual care to enhance adherence to HAART among HIV patients in Yaoundé, Cameroon. Participants appreciated the idea of a timely SMS reminder, and cited the physician as a role model. They expressed concerns about privacy. Long-term life goals were a motivating factor to adhere. Overall, text messaging was viewed positively as a tool with a dual function of reminder and motivator. Messages coming from the attending physician may have a stronger impact. Trials investigating the use of text messages to improve adherence to HAART need to consider the content and timing of SMS, taking into account technical challenges and privacy.Keywords: focus groups, adherence, highly active antiretroviral therapy (HAART, text message, short message service (SMS, human immunodeficiency virus (HIV

    Full Text Available Background: Acquired immune deficiency syndrome (AIDS is now considered as a manageable chronic illness. There has been a dramatic reduction in human immunodeficiency virus (HIV related morbidity and mortality due to antiretroviral therapy. A high level of adherence (>95% is required for antiretroviral therapy to be effective. There are many barriers to adherence in both developed and developing countries. Aim: The aim of our study was to determine adherence levels and factors influencing adherence to antiretroviral therapy among people living with HIV. Materials and Methods: Using a cross-sectional study design, 116 HIV positive patients receiving antiretroviral therapy for at least 1 year were interviewed using a semi structured questionnaire. The collected data was analyzed using Statistical Product and Service Solutions (SPSS version 11.5. Chi-square test was done. A P value of < 0.05 was considered statistically significant. Results: Of 116 participants, 63.7% reported adherence ≥ 95%. Mean adherence index was 91.25%. Financial constraints, forgetting to take medication, lack of family care, depression, alcohol use, social stigma and side effects to antiretroviral therapy were barriers for adherence in our study. Conclusion: Adherence to antiretroviral therapy in south India is suboptimal. Intensive adherence counseling should be provided to all patients before initiation ofantiretroviral therapy. Health care providers must identify possible barriers to adherence at the earliest and provide appropriate solutions.

    2007-06-01

    Full Text Available Given that highly active antiretroviral therapy (HAART has been demonstrated useful to restore immune competence in type-1 human immunodeficiency virus (HIV-1-infected subjects, we evaluated the specific antibody response to influenza vaccine in a cohort of HIV-1-infected children on HAART so as to analyze the quality of this immune response in patients under antiretroviral therapy. Sixteen HIV-1-infected children and 10 HIV-1 seronegative controls were immunized with a commercially available trivalent inactivated influenza vaccine containing the strains A/H1N1, A/H3N2, and B. Serum hemagglutinin inhibition (HI antibody titers were determined for the three viral strains at the time of vaccination and 1 month later. Immunization induced a significantly increased humoral response against the three influenza virus strains in controls, and only against A/H3N2 in HIV-1-infected children. The comparison of post-vaccination HI titers between HIV-1+ patients and HIV-1 negative controls showed significantly higher HI titers against the three strains in controls. In addition, post vaccination protective HI titers (defined as equal to or higher than 1:40 against the strains A/H3N2 and B were observed in a lower proportion of HIV-1+ children than in controls, while a similar proportion of individuals from each group achieved protective HI titers against the A/H1N1 strain. The CD4+ T cell count, CD4/CD8 T cells ratio, and serum viral load were not affected by influenza virus vaccination when pre- vs post-vaccination values were compared. These findings suggest that despite the fact that HAART is efficient in controlling HIV-1 replication and in increasing CD4+ T cell count in HIV-1-infected children, restoration of immune competence and response to cognate antigens remain incomplete, indicating that additional therapeutic strategies are required to achieve a full reconstitution of immune functions.

    Full Text Available Aims: To ascertain and compare between highly active antiretroviral therapy (HAART and non-HAART patients, the stimulated salivary flow rates and unstimulated salivary flow rates (USFR and SSFR and to correlate the salivary flow rates with immune suppression. Materials and Methods: One hundred human-immuno deficiency virus seropositive patients attending RAGAS-YRG CARE were examined and divided into two groups, a HAART group (patients on combination antiretroviral therapy comprising 50 patients and a non-HAART group comprising 50 patients. The HAART group was followed every 3 months after the baseline visit (0 for a period of 9 months, during which a clinical oral examination and collection of unstimulated and stimulated saliva was done. Their salivary gland function was assessed using a xerostomia inventory during each visit. The study on non-HAART group was cross-sectional. Statistical Analysis: Statistical analysis were performed with the aid of the Statistical Package for the Social Sciences (SPSS version 10.05 software. Results: There was no significant difference in mean SSFR and USFR between the two groups at baseline. In the HAART group, the mean stimulated salivary flow rate increased from baseline to 3 months ( P = 0.02, with the increase being maintained at 6 months and 9 months. When salivary flow rates were correlated with Cluster of Differentiation, CD4 counts, patients in the HAART group with a CD4 ≤ 200 at 6 months visit had a higher mean stimulated salivary flow rate when compared with patients with CD4 ≥ 200 ( P = 0.02. The xerostomia inventory did not reveal any significant difference between the two groups and HAART was not significantly associated with xerostomia. Conclusion: In our study HAART was neither associated with xerostomia nor a reduction in salivary flow rate and immune suppression was not a significant factor for decreasing the salivary flow rate.

    Introduction Colonic infiltration by HIV occurs soon after infection, establishing a persistent viral reservoir and a barrier to cure. We investigated virologic and immunologic correlates of detectable colonic HIV RNA during acute HIV infection (AHI) and their response to antiretroviral treatment (ART). Methods From 49,458 samples screened for HIV, 74 participants were enrolled during AHI and 41 consented to optional sigmoidoscopy, HIV RNA was categorized as detectable (≥50 copies/mg) or undetectable in homogenized colon biopsy specimens. Biomarkers and HIV burden in blood, colon and cerebrospinal fluid were compared between groups and after 24 weeks of ART. Results Colonic HIV RNA was detectable in 31 participants (76%) and was associated with longer duration since HIV exposure (median 16 vs. 11 days, p=0.02), higher median plasma levels of cytokines and inflammatory markers (CXCL10 476 vs. 148 pg/mL, p=0.02; TNF-RII 1036 vs. 649 pg/mL, p<0.01; neopterin 2405 vs. 1368 pg/mL, p=0.01) and higher levels of CD8+ T cell activation in the blood (human leukocyte antigen - antigen D related (HLA-DR)/CD38 expression 14.4% vs. 7.6%, p <0.01) and colon (8.9% vs. 4.5%, p=0.01). After 24 weeks of ART, participants with baseline detectable colonic HIV RNA demonstrated persistent elevations in total HIV DNA in colonic mucosal mononuclear cells (CMMCs) (median 61 vs. 0 copies/106 CMMCs, p=0.03) and a trend towards higher total HIV DNA in peripheral blood mononuclear cells (PBMC) (41 vs. 1.5 copies/106 PBMCs, p=0.06). There were no persistent differences in immune activation and inflammation. Conclusions The presence of detectable colonic HIV RNA at the time of ART initiation during AHI is associated with higher levels of proviral DNA after 24 weeks of treatment. Seeding of HIV in the gut may have long-lasting effects on the size of persistent viral reservoirs and may represent an important therapeutic target in eradication strategies. PMID:27637172

    To evaluate the effects of HIV infection on T cell turnover, we examined levels of DNA synthesis in lymph node and peripheral blood mononuclear cell subsets by using ex vivo labeling with BrdUrd. Compared with healthy controls (n = 67), HIV-infected patients (n = 57) had significant increases in the number and fraction of dividing CD4+ and CD8+ T cells. Higher percentages of dividing CD4+ and CD8+ T cells were noted in patients with the higher viral burdens. No direct correlation was noted between rates of T cell turnover and CD4+ T cell counts. Marked reductions in CD4+ and CD8+ T cell proliferation were seen in 11/11 patients 1–12 weeks after initiation of highly active antiretroviral therapy (HAART). These reductions persisted for the length of the study (16–72 weeks). Decreases in naïve T cell proliferation correlated with increases in the levels of T cell receptor rearrangement excision circles. Division of CD4+ and CD8+ T cells increased dramatically in association with rapid increases in HIV-1 viral loads in 9/9 patients 5 weeks after termination of HAART and declined to pre-HAART-termination levels 8 weeks after reinitiation of therapy. These data are consistent with the hypothesis that HIV-1 infection induces a viral burden-related, global activation of the immune system, leading to increases in lymphocyte proliferation.

    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

    Full Text Available Introduction of highly active antiretroviral therapy has resulted in a significant reduction in morbimortality and significant changes in the causes of death among HIV/AIDS patients. For this reason, it has become essential to monitor survival and causes of death. We constructed a survival curve based on 597 adult patients notified as AIDS cases between 1997 and 2004, at the Hospital das Clínicas, Federal University of Pernambuco, Recife, Brazil. Among those patients, 150 (25% progressed to death by December, 2005. Of these, 119 were studied in detail. The data were collected from notification files of the State Health Department and the State Mortality Information System, and were complemented by analysis of medical records. These 597 patients had a survival rate of 88%, 86% and 82% after one, two and five years, respectively, and a 75% likelihood of surviving to 1,984 days (66 months. Most of the deaths occurred during the first months after the diagnosis (median, 129 days. Patients who died were predominantly young men who had sexual exposure and came from Recife (the state capital or its metropolitan region. When the patients were first seen, a large proportion had already presented severe signs of immunodeficiency. Comparing the patients within this group, the characteristics that were associated with lower survival were: male sex, hemoglobin < 10 mg/dL, lymphocytes < 1,000/mm³, use of fewer therapeutic drugs and antiretroviral regimens and non-introduction of protease inhibitors. Most of them died from AIDS-related diseases, particularly undefined respiratory infections.

    Objectives To examine the impact of antiretroviral therapy on the prevalence of oral candidiasis, recovery of oral Candida species (spp) and salivary levels of total secretory immunoglobulin A (SIgA) and Candida-specific SIgA in human immunodeficiency virus (HIV)-infected children. Methods Sixty six HIV-positive and 40 HIV-negative children were cross-sectionally examined for the presence of oral lesions. Whole stimulated saliva samples were collected for the identification of Candida spp using culture and measurement of total and specific SIgA using enzyme-linked immunosorbent assay (ELISA). Results HIV-positive children had a higher prevalence of oral candidiasis (p < 0.05); higher frequency of detection of Candida spp (p < 0.05) and higher levels of total (p < 0.05) and Candida-specific SIgA (p < 0.001) than did HIV-negative children. Among HIV-positive subjects, antiretroviral users had lower viral loads (p < 0.001), lower levels of Candida spp (p < 0.05) and total SIgA (p < 0.05) compared with antiretroviral non-users. Conclusions The use of antiretroviral therapy was associated with decreases in the prevalence of oral candidiasis. This diminished exposure to Candida spp was accompanied by decreases in levels of total and Candida-specific SIgA. PMID:19615660

    Full Text Available Immunization with a pandemic influenza A H1N1 2009 was recommended for HIV-infected patients. However, there is limited information concerning the impact of immunization with this vaccine on immune activation and HIV viral replication. In this study, 45 HIV-infected children and adolescents receiving antiretroviral therapy were immunized with a 2-dose series of nonadjuvated monovalent influenza A H1N1 2009 vaccine upon enrollment and approximately 1 month later. Immunogenicity was determined by haemagglutination inhibition assay. The level of immune activation was determined by identification of CD38 and HLA-DR on CD8+ T cells. Patients were divided into 2 groups which include patients who had an undetectable HIV viral load (HIV detectable group and patients who show virological failure (HIV nondetectable group. The results showed seroconversion rate of 55.2% in HIV nondetectable group, whereas 31.3% was found in HIV detectable group. Both groups of patients showed no major increase in immune activation after immunization. Interestingly, a decrease in the frequency of CD8+ T cells that coexpressed CD38 and HLA-DR was observed after immunization in both groups of patients. We suggested that immunization with influenza A H1N1 2009 vaccine can induce immune response to the pandemic virus without major impact on HIV viral replication and immune activation.

    Full Text Available Introduction: Metabolic abnormalities are often common among human immunodeficiency virus (HIV patients. The atherogenic index of plasma (AIP is increasingly being used as a screening tool for dyslipidemia as it predicts the presence of small, dense, and highly atherogenic low density lipoprotein (LDL and high density lipoprotein (HDL particles. The aim of this study was to identify the pattern and predictors of an abnormal atherogenic index in highly active antiretroviral therapy (HAART-naïve HIV patients. Materials and Methods: HAART-naïve patients with HIV infection were recruited for this cross-sectional study. Anthropometric indices, blood pressure, CD4 count, viral load, fasting blood glucose, and lipid profiles were determined. Total cholesterol (TCH/HDL, triglyceride (TG/HDL, and LDL/HDL ratios were calculated. The AIP was calculated as log (TG/HDL. The correlations between AIP and the other lipoprotein ratios and predictors of AIP were determined using stepwise multiple linear regression. P 0.24 constituted up to 226 (64% of the patients. There were significant correlations between AIP and CD4 count, body mass index, LDL, TCH/HDL, and LDL/HDL. Predictors of AIP were CD4 count, TCH/HDL, and LDL/HDL. Conclusion: Abnormal AIP is frequent in HAART-naïve HIV patients and is inversely related to their level of immunity. We recommend that AIP estimation should be part of baseline assessment of HIV patients before the commencement of therapy.

    Full Text Available Non-tuberculous mycobacteria are rare but important causes of infection in HIV-positive individuals. A 28-year-old HIV-positive male presented with a high fever, non-productive cough, right subcostal pain, splenomegaly, a very low CD4 count, elevated C-reactive protein and erythrocyte sedimentation rate, and a normal white blood cell count. The suspicion of tuberculosis (TB was very high, and sputum samples were positive for acid-fast bacilli. Standard quadruple anti-TB therapy was initiated, but once culture of the sample revealed Mycobacterium kansasii, pyrazinamide was withdrawn. Highly active antiretroviral therapy (HAART was initiated soon after, consisting of abacavir/lamivudine and efavirenz. The patient's general condition deteriorated 2 weeks after HAART initiation, which could have been due to the development of immune reconstitution inflammatory syndrome (IRIS. The patient recovered and was discharged in good condition. However, the results of resistance testing of the isolated organism arrived after discharge, and showed isoniazid and streptomycin resistance. This is the first case report of M. kansasii infection from Serbia and shows the difficulties encountered during the course of treatment.

    Full Text Available The present paper describes possible connections between antiretroviral therapies (ARTs used to treat human immunodeficiency virus (HIV infection and adverse drug reactions (ADRs encountered predominantly in the liver, including hypersensitivity syndrome reactions, as well as throughout the gastrointestinal system, including the pancreas. Highly active antiretroviral therapy (HAART has a positive influence on the quality of life and longevity in HIV patients, substantially reducing morbidity and mortality in this population. However, HAART produces a spectrum of ADRs. Alcohol consumption can interact with HAART as well as other pharmaceutical agents used for the prevention of opportunistic infections such as pneumonia and tuberculosis. Other coinfections that occur in HIV, such as hepatitis viruses B or C, cytomegalovirus, or herpes simplex virus, further complicate the etiology of HAART-induced ADRs. The aspect of liver pathology including liver structure and function has received little attention and deserves further evaluation. The materials used provide a data-supported approach. They are based on systematic review and analysis of recently published world literature (MedLine search and the experience of the authors in the specified topic. We conclude that therapeutic and drug monitoring of ART, using laboratory identification of phenotypic susceptibilities, drug interactions with other medications, drug interactions with herbal medicines, and alcohol intake might enable a safer use of this medication.

    Full Text Available Guillain-Barré syndrome (GBS has been reported in HIV-infected patients in association with the immune reconstitution syndrome whose symptoms can be mimicked by highly active antiretroviral therapy (HAART-mediated mitochondrial toxicity. We report a case of a 17-year-old, HIV-infected patient on HAART with a normal CD4 count and undetectable viral load, presenting with acute lower extremity weakness associated with lactatemia. Electromyography/nerve conduction studies revealed absent sensory potentials and decreased compound muscle action potentials, consistent with a diagnosis of acute motor and sensory axonal neuropathy. Lactatemia resolved following cessation of HAART; however, neurological deficits minimally improved over several months in spite of immune modulatory therapy. This case highlights the potential association between HAART, mitochondrial toxicity and acute axonal neuropathies in HIV-infected patients, distinct from the immune reconstitution syndrome.

    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

    Full Text Available Abstract Background The optimal stage for initiating antiretroviral therapies in HIV-1 bearing patients is still a matter of debate. Methods We present computer simulations of HIV-1 infection aimed at identifying the pro et contra of immediate as compared to deferred Highly Active Antiretroviral Therapy (HAART. Results Our simulations highlight that a prompt specific CD8+ cytotoxic T lymphocytes response is detected when therapy is delayed. Compared to very early initiation of HAART, in deferred treated patients CD8+ T cells manage to mediate the decline of viremia in a shorter time and, at interruption of therapy, the virus experiences a stronger immune pressure. We also observe, however, that the immunological effects of the therapy fade with time in both therapeutic regimens. Thus, within one year from discontinuation, viral burden recovers to the value at which it would level off in the absence of therapy. In summary, simulations show that immediate therapy does not prolong the disease-free period and does not confer a survival benefit when compared to treatment started during the chronic infection phase. Conclusion Our conclusion is that, since there is no therapy to date that guarantees life-long protection, deferral of therapy should be preferred in order to minimize the risk of adverse effects, the occurrence of drug resistances and the costs of treatment.

    Full Text Available Objectives: To determine if long-term highly active antiretroviral therapy (HAART therapy alters salivary flow rate and also to compare its relation of CD4 count with unstimulated and stimulated whole saliva. Materials and Methods: A cross-sectional study was performed on 150 individuals divided into three groups. Group I (50 human immunodeficiency virus (HIV seropositive patients, but not on HAART therapy, Group II (50 HIV-infected subjects and on HAART for less than 3 years called short-term HAART, Group III (50 HIV-infected subjects and on HAART for more than or equal to 3 years called long-term HAART. Spitting method proposed by Navazesh and Kumar was used for the measurement of unstimulated and stimulated salivary flow rate. Chi-square test and analysis of variance (ANOVA were used for statistical analysis. Results: The mean CD4 count was 424.78 ΁ 187.03, 497.82 ΁ 206.11 and 537.6 ΁ 264.00 in the respective groups. Majority of the patients in all the groups had a CD4 count between 401 and 600. Both unstimulated and stimulated whole salivary (UWS and SWS flow rates in Group I was found to be significantly higher than in Group II (P < 0.05. Unstimulated salivary flow rate between Group II and III subjects were also found to be statistically significant (P < 0.05. ANOVA performed between CD4 count and unstimulated and stimulated whole saliva in each group demonstrated a statistically significant relationship in Group II (P < 0.05. There were no significant results found between CD4 count and stimulated whole saliva in each groups. Conclusion:The reduction in CD4 cell counts were significantly associated with salivary flow rates of HIV-infected individuals who are on long-term HAART.

    Children infected with human immunodeficiency virus (HIV) are at particular risk for psychological disturbance. Little is known about the mental health status of children on highly active antiretroviral therapy (HAART). A hospital-based cross-sectional study of 318 children aged 6-14 on HAART in Addis Ababa was conducted. Behavioral and emotional problem was assessed using the child behavior check list (CBCL/6-18). Logistic regression analysis was done to select the best subset of predictor variables and determine their association with behavioral and emotional problems. Of the 318 caregivers of children aged 6-14 on HAART, 39.3% of the children had behavioral and emotional problems. Low family monthly income (AOR, 3.44, 95% CI, 1.89-6.25), older age (AOR, 2.27, 95% CI, 1.34-3.83), and parental loss (AOR, 1.89, 95% CI, 1.10-3.25) were found to be determinants of behavioral and emotional problems in the multivariate logistic regression. There is high prevalence of behavioral and emotional problems in children on HAART in Addis Ababa. More support is needed to children from families of low income and those who lost their parents. Further research should be carried out to enhance better understanding and appropriate response to behavioral and emotional problems.

    Since 2010, the Pharmacie et Aide Humanitaire (PAH) in Casamance (Senegal) has been maintaining a software package (Tacojo) that allows monthly monitoring of the distribution of treatment to every patient with HIV infection receiving highly active antiretroviral therapy (HAART). We used this program to set up measures to prevent the loss to follow-up of patients receiving HAART. Our involvement focused on two main areas. First, each patient is routinely contacted after inclusion, to help us to understand the patient's experience of the disease and the treatment. This process aims to improve adherence to the treatment. Then, all patients who miss an appointment are routinely contacted by telephone within seven days of that appointment. The goal is to understand the reasons for the absence and to encourage patients to continue their treatment. Despite the lack of distance due to the relative newness of this program, these preventive measures have shown hopeful results (80% of the patients came back after a call). It would be interesting to apply it in a sustainable manner and in more medical facilities. PMID:27412981

    Full Text Available Purpose: To evaluate the outcome of surgery for cytomegalovirus associated retinal detachment (CMVRD in human immunodeficiency virus (HIV-infected patients in pre-highly active antiretroviral therapy (HAART and HAART era in Indian eyes. Materials and Methods: Retrospective, we reviewed medical records of all consecutive HIV patients, who underwent surgical repair for CMVRD from July 1998 to June 2011. We divided patients into two groups, i.e. group 1, pre HAART era and group 2, HAART era. We compared two groups for various parameters like visual outcome, surgical success, additional procedures, follow-up, etc., Results: Twenty-eight eyes of 26 patients were included; 12 eyes of the 11 patients in group 1 and 16 eyes of the 15 patients in group 2. Significant visual acuity improvement was seen in both groups. Complete anatomic success was seen in 11 eyes in group 1 and 15 eyes in group 2. One additional procedure in group 1 and 29 additional procedures were done in group 2. A mean follow-up was 16 months in group 1 and 41 months in group 2. Conclusion: There was no difference in outcome in pre-HAART and HAART group, except for longer follow-up and additional surgical procedures in HAART group.

    Full Text Available Background: Crystalluria is associated with some highly active anti-retroviral therapies (HAART′s used in the management of HIV/AIDS. Aims: This study used light microscopy to establish the prevalence of crystalluria among HIV/AIDS patients on HAART and identified the routine crystals present in their urine. Materials and Methods: In this simple randomised cross-sectional study, 200 HIV/AIDS participants, comprising 150 on HAART and 50 HAART-naοve were recruited from the HIV clinic at the Komfo Anokye Teaching Hospital (KATH. Urine and blood samples were collected, for urinalysis and the determination of the CD4 count, respectively. A well-structured pre-tested questionnaire was used to obtain socio-demographic data and clinical history of the participants. Results: The prevalence of crystalluria was higher among HIV-infected persons on HAART than those not on HAART (6.7% vs 4%; P = 0.733. Calcium oxalate and triple phosphate crystals were the crystal types present in their urine (3.5% and 2.5%, respectively and was present only in HIV subjects on first line of treatment (without protease inhibitors. Participants aged between 40-50 years and those with hypersthenuria and acidic urine had the highest amount of crystalluria (41.6%, 83.3%, and 58.3%, respectively. Conclusion: HAART is associated with crystalluria in HIV patients. Light microscopy will be of disgnostic value in resource limited settings.

    This study was conducted to determine the impact of immune activation, cytokine production and apoptosis on the naive CD4+ cell count and the function of hematopoietic progenitor cells during the initial phase of highly active antiretroviral therapy (HAART). Blood samples from 11 HIV......-infected patients were collected prior to HAART and after 4 and 12 weeks of therapy. Flow cytometry was used to determine the naive CD4+ count and activated T cells. The cloning efficiency of progenitor cells was determined using a colony-forming cells assay. Finally, apoptosis and cytokine production were...... cells. A negative correlation was found between apoptosis and the naive CD4+ count. Alterations in cytokine production during HAART or correlation between cytokine production and the naive CD4+ count or the cloning efficiency of progenitor cells were not detected. In conclusion, immune activation in HIV...

    Full Text Available BACKGROUND: Access to highly active antiretroviral therapy (HAART is expanding in Latin America. Many patients require second and third line therapy due to toxicity, tolerability, failure, or a combination of factors. The need for third line HAART, essential for program planning, is not known. METHODS: Antiretroviral-naïve patients ≥18 years who started first HAART after January 1, 2000 in Caribbean, Central and South America Network (CCASAnet sites in Argentina, Brazil, Honduras, Mexico, and Peru were included. Clinical trials participants were excluded. Third line HAART was defined as use of darunavir, tipranavir, etravirine, enfuvirtide, maraviroc or raltegravir. Need for third line HAART was defined as virologic failure while on second line HAART. RESULTS: Of 5853 HAART initiators followed for a median of 3.5 years, 310 (5.3% failed a second line regimen and 44 (0.8% received a third line regimen. Cumulative incidence of failing a 2nd or starting a 3rd line regimen was 2.7% and 6.0% three and five years after HAART initiation, respectively. Predictors at HAART initiation for failing a second or starting a third line included female sex (hazard ratio [HR] = 1.54, 95% confidence interval [CI] 1.18-2.00, p = 0.001, younger age (HR = 2.76 for 20 vs. 40 years, 95% CI 1.86-4.10, p<0.001, and prior AIDS (HR = 2.17, 95% CI 1.62-2.90, p<0.001. CONCLUSIONS: Third line regimens may be needed for at least 6% of patients in Latin America within 5 years of starting HAART, a substantial proportion given the large numbers of patients on HAART in the region. Improved accessibility to third line regimens is warranted.

    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.

  7. Diagnosis, antiretroviral therapy, and emergence of resistance to antiretroviral agents in HIV-2 infection: a review

    Directory of Open Access Journals (Sweden)

    Maia Hightower

    2003-02-01

    Full Text Available Human immunodeficiency virus type 1 (HIV-1 and type 2 (HIV-2 are the causative agents of AIDS. HIV-2 is prevalent at moderate to high rates in West African countries, such as Senegal, Guinea, Gambia, and Cape Verde. Diagnosis of HIV-2 is made with a positive HIV-1/HIV-2 ELISA or simple/rapid assay, followed by one or two confirmatory tests specific for HIV-2. Following CD4+ T cell counts, HIV-2 viral burden and clinical signs and symptoms of immunodeficiency are beneficial in monitoring HIV-2 disease progression. Although non-nucleoside reverse transcriptase inhibitors are ineffective in treating HIV-2, nucleoside reverse transcriptase inhibitors and protease inhibitors can be effective in dual and triple antiretroviral regimens. Their use can decrease HIV-2 viral load, increase CD4+ T cell counts and improve AIDS-related symptoms. HIV-2 resistance to various nucleoside reverse transcriptase inhibitors and protease inhibitors, including zidovudine, lamivudine, ritonavir and indinavir, has been identified in some HIV-2 infected patients on antiretroviral therapy. The knowledge of HIV-2 peculiarities, when compared to HIV-1, is crucial to helping diagnose and guide the clinician in the choice of the initial antiretroviral regimen and for monitoring therapy success.

    Full Text Available Abstract Background The psychosocial development of pediatric HIV patients has not been extensively evaluated. The study objectives were to evaluate whether emotional and social functions are differentially associated with HIV-related complications. Methods A matched case-control study design was conducted. The case group (n = 20 consisted of vertically infected children with HIV (aged 3-18 years receiving HAART in Greece. Each case was matched with two randomly selected healthy controls from a school-based population. CNS imaging and clinical findings were used to identify patients with HIV-related neuroimaging abnormalities. The Wechsler Intelligence Scale III and Griffiths Mental Abilities Scales were applied to assess cognitive abilities. The age specific Strengths and Difficulties Questionnaire was used to evaluate emotional adjustment and social skills. The Fisher's exact test, student's t-test, and Wilcoxon rank sum test were used to compare categorical, continuous, and ordinal scores, respectively, of the above scales between groups. Results HIV patients without neuroimaging abnormalities did not differ from patients with neuroimaging abnormalities with respect to either age at HAART initiation (p = 0.306 or months of HAART treatment (p = 0.964. While HIV patients without neuroimaging abnormalities had similar cognitive development with their healthy peers, patients with neuroimaging abnormalities had lower mean General (p = 0.027 and Practical (p = 0.042 Intelligence Quotient scores. HIV patients without neuroimaging abnormalities had an increased likelihood of both Abnormal Emotional Symptoms (p = 0.047 and Hyperactivity scores (p = 0.0009. In contrast, HIV patients with neuroimaging abnormalities had an increased likelihood of presenting with Abnormal Peer Problems (p = 0.033. Conclusions HIV patients without neuroimaging abnormalities are more likely to experience maladjustment with respect to their emotional and activity spheres

    Full Text Available It is generally accepted that oxidative stress is involved in HIV infection. However, the role in oxidative balance of Highly Active Antiretroviral Therapy (HAART is still debated. In our study we assessed serum oxidant and antioxidant levels in an HIV-1-infected population treated with HAART, and compared them with those of untreated HIV-1 patients and HIV-1-negative subjects. The study included 116 HIV-1-infected patients (86 HAART-treated and 30 untreated, and 46 HIV-negative controls. Serum oxidant levels were significantly higher in the HIV-1 treated group as compared to untreated and control groups. In addition, a decrease of serum total antioxidant status was observed in the HIV-1 treated group. To be noted is that patients who rigorously follow antiretroviral therapy (optimal HAART adherence have significantly higher oxidative status than those who do not closely follow the therapy (poor HAART adherence. Analysis of variance revealed no significant further increase in oxidative status in HIV-1-infected patients taking antiretroviral and other drugs with the exception of psychiatric drugs (e.g. anxiolytics or antidepressants. Taken together, our results indicate that HAART may affect oxidative stress in HIV-1-infected patients and suggest that antiretroviral therapy plays an important role in the synergy of HIV infection and oxidative stress.

    CD4 recovery in HIV-infected patients treated with highly active antiretroviral therapy (HAART) is in part believed to be dependent on the degree of preserved thymic function. We investigated whether the thymus has a prolonged effect on CD4 recovery. Total and naïve CD4 counts as well as thymic...... with larger thymic size at follow-up. However, no difference in the increase in thymic output was seen between thymic groups. In conclusion, the importance of the thymus to the rate of cellular restoration seems primarily to lie within the first two years of HAART. However, patients with larger thymic size...

    Full Text Available Access to highly active anti-retroviral therapy (HAART has improved the prognosis of Nigerian children infected with the human immunodeficiency virus (HIV; thus, more children are surviving. Long-term exposure to HAART is potentially nephrotoxic. We therefore aimed at assessing the prevalence of renal disease in Nigerian children infected with HIV, who are on HAART. In this cross-sectional study, we studied children, aged ten months to 17 years, infected with HIV, attending the pediatric HIV clinics of the University of Benin Teaching Hospital. Demographic and clinical data were obtained by parental interview as well as from the medical records. Each child′s urine was tested for albumin and microalbuminuria using multi test strips and mitral test strips, respectively. The serum creatinine level of each child was also estimated and used in calculating the glomerular filtration rate (GFR. Renal disease was defined as the presence of significant proteinuria of 1+ and above on dipstick or the presence of microalbuminuria of ≥20 mg and/or GFR <60 mL/min/1.73 m 2 . Of the 99 children recruited, 60 were males and 39 were females. The mean age of the children was 6.6 ± 3.5 years. All the children were on HAART and 85% had acquired the HIV infection by vertical transmission. The overall prevalence of renal disease was 16.2%. Microalbuminuria was seen in 11 children with renal disease (11.1%; 3 of them had significant proteinuria. GFR of less than 60 mL/min/1.73 m 2 was seen in five children (5.1% with renal disease, but none had end-stage renal disease (GFR less than 15 mL/min/1.73 m 2 . Renal disease was found to be significantly associated with advanced stage of HIV infection (P < 0.049. Our study showed that t he prevalence of renal disease in HAART-treated Nigerian children is high and majority of them are asymptomatic of renal disease, but in the advanced stages of HIV infection.

    Full Text Available Approximately 4 million of people are co-infected with HIV and Hepatitis B virus (HBV. In resource-limited settings, the majority of HIV-infected patients initiate first-line highly active antiretroviral therapy containing lamivudine (3TC-containing-HAART and long-term virological response of HBV to lamivudine-containing HAART in co-infected patients is not well known.HIV-HBV co-infected patients enrolled in the PHPT cohort (ClinicalTrials.gov NCT00433030 and initiating a 3TC-containing-HAART regimen were included. HBV-DNA, HIV-RNA, CD4+ T-cell counts and alanine transaminase were measured at baseline, 3 months, 12 months and then every 6 months up to 5 years. Kaplan-Meier analysis was used to estimate the cumulative rates of patients who achieved and maintained HBV-DNA suppression. Of 30 co-infected patients, 19 were positive for HBe antigen (HBeAg. At initiation of 3TC-containing-HAART, median HBV DNA and HIV RNA levels were 7.35 log(10 IU/mL and 4.47 log(10 copies/mL, respectively. At 12 months, 67% of patients achieved HBV DNA suppression: 100% of HBeAg-negative patients and 47% of HBeAg-positive. Seventy-three percent of patients had HIV RNA below 50 copies/mL. The cumulative rates of maintained HBV-DNA suppression among the 23 patients who achieved HBV-DNA suppression were 91%, 87%, and 80% at 1, 2, and 4 years respectively. Of 17 patients who maintained HBV-DNA suppression while still on 3TC, 4 (24% lost HBsAg and 7 of 8 (88% HBeAg-positive patients lost HBeAg at their last visit (median duration, 59 months. HBV breakthrough was observed only in HBeAg-positive patients and 6 of 7 patients presenting HBV breakthrough had the rtM204I/V mutations associated with 3TC resistance along with rtL180M and/or rtV173L.All HBeAg-negative patients and 63% of HBeAg-positive HIV-HBV co-infected patients achieved long-term HBV DNA suppression while on 3TC-containing-HAART. This study provides information useful for the management of co-infected patients

    Background The WHO recommends boosted protease inhibitor (bPI)-based highly active antiretroviral therapy (HAART) after failing non-nucleoside reverse transcriptase inhibitor (NNRTI) treatment. We examined outcomes of this regimen in Asian HIV-infected children. Methods Children from five Asian countries in the TREAT Asia Pediatric HIV Observational Database (TApHOD) with ≥24 weeks of NNRTI-based HAART followed by ≥24 weeks of bPI-based HAART were eligible. Primary outcomes were the proportions with virologic suppression (HIV-RNA <400 copies/ml) and immune recovery (CD4% ≥25% if age <5 years and CD4 count ≥500 cells/mm3 if age ≥5 years) at 48 and 96 weeks. Results Of 3422 children, 153 were eligible; 52% were female. At switch, median age was 10 years, 26% were in WHO stage 4. Median weight-for-age z-score (WAZ) was −1.9 (n=121), CD4% was 12.5% (n=106), CD4 count was 237 (n=112) cells/mm3, and HIV-RNA was 4.6 log10copies/ml (n=61). The most common PI was lopinavir/ritonavir (83%). At 48 weeks, 61% (79/129) had immune recovery, 60% (26/43) had undetectable HIV-RNA and 73% (58/79) had fasting triglycerides ≥130mg/dl. By 96 weeks, 70% (57/82) achieved immune recovery, 65% (17/26) virologic suppression, and hypertriglyceridemia occurred in 66% (33/50). Predictors for virologic suppression at week 48 were longer duration of NNRTI-based HAART (p=0.006), younger age (p=0.007), higher WAZ (p=0.020), and HIV-RNA at switch <10,000 copies/ml (p=0.049). Conclusion In this regional cohort of Asian children on bPI-based second-line HAART, 60% of children tested had immune recovery by one year, and two-thirds had hyperlipidemia, highlighting difficulties in optimizing second-line HAART with limited drug options.

    Full Text Available The aim of this study was to determine the prevalence of non-tuberculous mycobacteria (NTM isolates at University Hospital, Reference Center for Aids in Rio de Janeiro, Brazil, during one year. We used standard biochemical tests for species identification and IS1245 PCR amplification was applied as a Mycobacterium avium specific identification marker. Four hundred and four specimens from 233 patients yielded acid-fast bacilli growth. M. tuberculosis was identified in 85% of the patients and NTM in 15%. NTM disseminated infection was a common event correlated with human immunodeficiency virus (HIV infected patients and only in HIV negative patients the source of NTM was non sterile site. M. avium complex (MAC was biochemically identified in 57.8% (49/83 of NTM isolates, most of them from sterile sites (75.5%, and in 94% (46/49 the IS 1245 marker specific for M. avium was present. Twenty NTM strains showed a MAC biochemical pattern with the exception of a urease-positive (99% of MAC are urease-negative, however IS1245 was detected in 96% of the strains leading to their identification as M. avium. In this group differences in NTM source was not significant. The second most frequently isolated NTM was identified as M. scrofulaceum (7.2%, followed by M. terrae (3.6%, M. gordonae (2.4%, M. chelonae (1.2%, M. fortuitum (1.2% and one strain which could not be identified. All were IS1245 negative except for one strain identified as M. scrofulaceum. It is interesting to note that non-sterile sites were the major source of these isolates (92.8%. Our finding indicated that M. avium is still the major atypical species among in the MAC isolates recovered from Brazilian Aids patients without highty active antiretroviral therapy schema. Some discrepancies were seen between the identification methods and further investigations must be done to better characterize NTM isolates using other phenotypic and genotypic methods.

    Full Text Available OBJECTIVES: To investigate the duration of sequential HAART regimens and predictors of first-line regimen discontinuation among HIV-1 vertically infected children and adolescents. DESIGN: Multicentre survey of antiretroviral-naïve patients enrolled in the HIV-Paediatric Cohor,t CoRISpeS-Madrid Cohort, Spain. METHODS: Patients with a follow-up of ≥ 1 month spent on HAART, with available baseline CD4 count and HIV-viral load (VL were included. Time spent on sequential HAART regimens was estimated and multivariable regression was used to identify predictors of time to first-line regimen discontinuation. RESULTS: 104 patients were followed for a median 8 years after starting HAART among 1996-2012; baseline %CD4 was 21.5 (12.3-34.0and viral load was 5.1 (4.6-5.6 log10 copies/mL. Patients received a mean of 1.9 regimens. Median time on first-line HAART (n = 104 was 64.5 months; second HAART (n = 56 69.8 months; and third HAART (n = 21 66.5 months. Eleven (11% patients were lost to follow-up while on first-line HAART and 54% discontinued (cumulative incidence of 16% and 38% by 1 and 3-year, respectively. The main predictor of first-line regimen discontinuation was suboptimal adherence to antiretrovirals (AHR: 2.60; 95% CI: 1.44-4.70. CONCLUSIONS: Adherence to therapy was the main determinant of the duration of the first-line HAART regimen in children. It is important to identify patients at high risk for non-adherence, such as very young children and adolescents, in provide special care and support to those patients.

    2005-06-01

    An unprecedented international effort to expand high activity antiretroviral therapy (HAART) to resource-poor nations has been launched. The World Health Organization (WHO) has created antiretroviral (ARV) treatment guidelines adapted to resource-poor settings. The first-line regimen is two nucleoside reverse transcriptase inhibitors (NsRTIs) and one nonnucleoside reverse transcriptase inhibitor (NNRTI). Therapy is initiated by clinical staging and CD4 T-cell counts when available. Adherence is the responsibility of health care workers. The use of ARV therapy in resource-poor settings faces several challenges, including the poverty of patients, political and social upheavals and violence, social stigma associated with HIV/AIDS, unreliable pharmacy systems, tuberculosis, and lack of trained health care workers.

    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.

    To assess the impact of vaccination with 23-valent pneumococcal polysaccharide vaccine on the risks for development of pneumococcal disease, all-cause community-acquired pneumonia, HIV progression, and mortality and immunologic and virologic responses among HIV-1-infected patients treated with highly active antiretroviral therapy (HAART), we conducted a 2-year prospective observational cohort study at a university hospital in Taiwan. A total of 305 HIV-1-infected patients who received 23-valent pneumococcal vaccine (vaccinees) and 203 patients who did not (non-vaccinees) were prospectively observed between 1 June 2000 and 31 October 2002. Changes of CD4+ and plasma viral load (PVL) from baseline to week 4 of vaccination were assessed in 31 randomly selected vaccinees. The incidence of pneumococcal disease and bacteremia of vaccinees was 2.1 per 1000 patient-years (PY) (95% confidence interval (95% CI), 1.7-2.5 per 1000 PY) over the median observation of 641 days (range, 37-832 days) following vaccination while that of non-vaccinee was 21.8 per 1000 PY (95% CI, 20.1-23.7 per 1000 PY) and 7.3 per 1000 PY (95% CI, 7.0-7.6 per 1000 PY), respectively, over the observation of 500 days (range, 32-851 days), with an adjusted odds ratio (AOR) for developing pneumococcal disease of 0.085 (95% CI, 0.010-0.735) and for bacteremia of 0.22 (95% CI, 0.018-2.561). The median CD4+ count increased by 45 x 10(6) l(-1) (P = 0.01) and median PVL change was 0 log(10) copies/ml (range of decrease, -0.74 to 2.47 log(10) copies/ml) after 1 month of pneumococcal vaccination among the subgroup of 31 vaccinees receiving HAART. The median CD4+ count increase from baseline to the end of study was 149 x 10(6) l(-1) for vaccinees and 107 x 10(6) l(-1) for non-vaccinees (P = 0.21). The AOR of developing all-cause community-acquired pneumonia and new AIDS-defining opportunistic illnesses (OI) of vaccinees as compared to non-vaccinees was 1.876 (95% CI, 0.785-4.485) and 0.567 (95% CI, 0

    Full Text Available We report 2 cases illustrating that it is too simplistic to link nevirapine (NVP toxicity exclusively to individuals with immune preservation. Not enough is known about the mechanism of hepatotoxicity or cutaneous eruption to predict these events. This type of hypersensitivity reaction occurs rarely among HIV-exposed infants taking NVP prophylaxis or antiretroviral therapy (ART-experienced adults with complete plasma viral load suppression. Conversely, HIV-uninfected adults and ART-naive pregnant women appear to be disproportionately affected by the adverse effects of NVP.

    This study aimed to compare the outcome of an elderly group of AIDS patients with that of a younger group and their features at the time of the diagnosis of AIDS. We evaluated 58 patients aged >60 years and 114 aged 20-39 years, followed for 35.3 months. There was an obvious delay in diagnosing the elderly as they had more AIDS-defining diseases at diagnosis and their most frequent opportunistic infection was pulmonary tuberculosis. Mortality at the time of the diagnosis of AIDS was four times higher in the elderly (24.1% versus 6.1%, P therapy, there was a similar frequency of favourable outcomes; 76.9% in the elderly against 83.1% in the young (P = 0.455). Mean CD4 lymphocyte was 438 cells/mm(3) at the end of follow up in the young when compared with 442 cells/mm(3) in the elderly (P = 0.945). The types of antiretroviral schema and the number of antivirals per patient were similar in both groups.

    Full Text Available BACKGROUND: Although women of reproductive age are the largest group of HIV-infected individuals in sub-Saharan Africa, little is known about the impact of pregnancy on response to highly active antiretroviral therapy (HAART in that setting. We examined the effect of incident pregnancy after HAART initiation on virologic response to HAART. METHODS AND FINDINGS: We evaluated a prospective clinical cohort of adult women who initiated HAART in Johannesburg, South Africa between 1 April 2004 and 30 September 2009, and followed up until an event, death, transfer, drop-out, or administrative end of follow-up on 31 March 2010. Women over age 45 and women who were pregnant at HAART initiation were excluded from the study; final sample size for analysis was 5,494 women. Main exposure was incident pregnancy, experienced by 541 women; main outcome was virologic failure, defined as a failure to suppress virus to ≤ 400 copies/ml by six months or virologic rebound >400 copies/ml thereafter. We calculated adjusted hazard ratios using marginal structural Cox proportional hazards models and weighted lifetable analysis to calculate adjusted five-year risk differences. The weighted hazard ratio for the effect of pregnancy on time to virologic failure was 1.34 (95% confidence limit [CL] 1.02, 1.78. Sensitivity analyses generally confirmed these main results. CONCLUSIONS: Incident pregnancy after HAART initiation was associated with modest increases in both relative and absolute risks of virologic failure, although uncontrolled confounding cannot be ruled out. Nonetheless, these results reinforce that family planning is an essential part of care for HIV-positive women in sub-Saharan Africa. More work is needed to confirm these findings and to explore specific etiologic pathways by which such effects may operate.

    In patients with human immunodeficiency virus (HIV) infection, neutrophil and monocyte functions, including phagocytosis, are impaired. The purpose of this study was to investigate changes of phagocytic function and respiratory burst occurring over the course of patients infected by the HIV-1 virus. Treatment-naive patients (group B), patients receiving highly active anti-retroviral treatment (HAART) (group C) and patients in which HAART has failed (group D) were studied and compared with healthy volunteers (group A). Phagocytosis and oxidative burst were evaluated using commercially available kits. Results clearly denote a significant decrease of the phagocytic function of both cell types of groups B and C compared with group A. Among group C patients, those in the upper quartile of CD4 increase had higher oxidative burst compared with patients of the other quartiles. In addition, comparisons clearly showed a lower degree of phagocytic function and of oxidative burst of both monocytes and neutrophils of group D compared with group B. Finally, it was found that monocyte and neutrophil function was correlated inversely to the change in viral load, i.e. the greater the decrease of viral load, the better the phagocytic and oxidative activity. Innate immunity defects appear to be present in HIV-positive patients, regarding phagocytic activity and oxidative burst of monocytes and neutrophils. These defects are greatly influenced by the level of treatment efficacy, with emphasis on CD4 cell counts and viral load. PMID:22288593

    Full Text Available BACKGROUND: In the developing world, the principal cause of death among HIV-infected patients is tuberculosis (TB. The initiation of antiretroviral therapy (ART during TB therapy significantly improves survival, however it is not known which barriers prevent eligible TB patients from initiating life-saving ART. METHOD: Setting. A South African township clinic with integrated tuberculosis and HIV services. Design. Logistic regression analyses of a prospective cohort of HIV-1 infected adults (≥18 years who commenced TB therapy, were eligible for ART, and were followed for 6 months. FINDINGS: Of 100 HIV-1 infected adults eligible for ART during TB therapy, 90 TB patients presented to an ART clinic for assessment, 66 TB patients initiated ART, and 15 TB patients died. 34% of eligible TB patients (95%CI: 25-43% did not initiate ART. Male gender and younger age (<36 years were associated with failure to initiate ART (adjusted odds ratios of 3.7 [95%CI: 1.25-10.95] and 3.3 [95%CI: 1.12-9.69], respectively. Death during TB therapy was associated with a CD4+ count <100 cells/µL. CONCLUSION: In a clinic with integrated services for tuberculosis and HIV, one-third of eligible TB patients--particularly young men--did not initiate ART. Strategies are needed to promote ART initiation during TB therapy, especially among young men.

    Full Text Available Abstract Background To increase access to antiretroviral therapy in resource-limited settings, several experts recommend "task shifting" from doctors to clinical officers, nurses and midwives. This study sought to identify task shifting that has already occurred and assess the antiretroviral therapy training needs among clinicians to whom tasks have shifted. Methods The Infectious Diseases Institute, in collaboration with the Ugandan Ministry of Health, surveyed health professionals and heads of antiretroviral therapy clinics at a stratified random sample of 44 health facilities accredited to provide this therapy. A sample of 265 doctors, clinical officers, nurses and midwives reported on tasks they performed, previous human immunodeficiency virus training, and self-assessment of knowledge of human immunodeficiency virus and antiretroviral therapy. Heads of the antiretroviral therapy clinics reported on clinic characteristics. Results Thirty of 33 doctors (91%, 24 of 40 clinical officers (60%, 16 of 114 nurses (14% and 13 of 54 midwives (24% who worked in accredited antiretroviral therapy clinics reported that they prescribed this therapy (p Conclusion Training initiatives should be an integral part of the support for task shifting and ensure that antiretroviral therapy is used correctly and that toxicity or drug resistance do not reverse accomplishments to date.

    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 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

In this population, up to 70-80% of cases may present as extranodal location as the primary clinical manifestation of the neoplasm disease. Gastrointestinal tract is the most frequent location of AIDS-associated NHL. However, salivary gland involvement, including the parotid gland is a rare complication in human immunodeficiency virus (HIV-patients. Here, we describe a patient seropositive for the HIV, who developed a primary NHL of the parotid gland histologically classified as a high-grade diffuse large B-cell lymphoma. Patient was treated with a combination of chemotherapy plus highly active antiretroviral therapy with a good clinical, virological and immunological response and a prolonged survival, more than 5 years, without evidence of neoplasm relapse.

    2016-05-01

    This paper examines the effects of antiretroviral therapy (ART) on demand for HIV testing and of ART-induced testing on demand for risky sexual behavior. I provide a model of sexual behavior decision-making under uncertainty and estimate the structural parameters of the model using nationally representative survey data from Zambia on HIV testing decisions before and after the introduction of ART. The empirical results indicate that although the introduction of ART appears to have increased HIV testing rates by upwards of 50 percent, the ART allocation process may have limited the prevention benefit of ART-induced testing. Simulation results show that eliminating this prevention inefficiency while holding the supply of ART constant would increase the prevention impact of ART-induced testing more than four-fold. More generally, the analysis indicates that existing studies which examine "universal" testing or quasi-experimental testing programs understate the efficacy of standard voluntary counseling and testing programs.

    Full Text Available Optic neuropathy in HIV-infected patients results from the HIV infection itself, post-infectious auto-immune disease, opportunistic infections and drugs. Nucleoside reverse transcriptase inhibitors (NRTIs such as zidovudine and stavudine have known mitochondrial toxicity and can cause mitochondrial myopathies, neuropathies, hyperlactataemia, and can induce mitochondrial genetic disorders. Individuals with the mutation for Leber’s hereditary optic neuropathy (LHON, a mitochondrial disorder, are usually asymptomatic but develop visual loss when exposed to external triggers such as smoking. We report on two HIV-infected patients with LHON mutations (m.14484T>C and m.11778G>A who developed profound visual loss with antiretroviral therapy. We postulate that the phenotypic expression of LHON in these genetically predisposed individuals was triggered by NRTI drugs lamivudine and tenofovir when used in combination, despite their relatively weak mitochondrial toxic effects.

  8. Public health implications of antiretroviral therapy and HIV drug resistance.

    1998-06-24

    Widespread use of antiretroviral agents and increasing occurrence of human immunodeficiency virus (HIV) strains resistant to these drugs have given rise to a number of important issues. Some of these concerns are distinct from the obvious question of the relationship between drug resistance and treatment failure and have potentially widespread public health implications. The relevant issues include but are not limited to the following: (1) frequency with which drug-resistant virus may be transmitted via sexual, intravenous, or mother-to-child routes; (2) ability of drug-resistant variants to be transmitted, a question that relates, in part, to the relative fitness of such strains; (3) effectiveness of antiviral therapy in diminishing viral burden in both blood and genital secretions, and whether this may be compromised in persons harboring resistant virus; and (4) importance of patient adherence to antiviral therapy and its relationship to sustained reduction in viral load to minimize the appearance in and transmission of drug-resistant virus from both blood and genital secretions. Thus, prevention of both development of HIV drug resistance as well as transmission of drug-resistant variants is a central issue of public health importance. Unless this topic is appropriately addressed, the likelihood is that drug-resistant variants of HIV, if able to successfully replicate, will sustain the epidemic and limit the effectiveness of antiviral therapy.

    Oropharyngeal candidiasis (OPC) remains a common problem in the HIV-infected population despite the availability of antiretroviral therapy (ART). Although Candida albicans is the most frequently implicated pathogen, other Candida spp. may also cause infection. The emergence of antifungal resistance within these causative yeasts, especially in patients with recurrent oropharyngeal infection or with long-term use of antifungal therapies, requires a working knowledge of alternative antifungal agents. Identification of the infecting organism and antifungal susceptibility testing enhances the ability of clinicians to prescribe appropriate antifungal therapy. Characterization of the responsible mechanisms has improved our understanding of the development of antifungal resistance and could enhance the management of these infections. Immune reconstitution has been shown to reduce rates of oropharyngeal candidiasis but few studies have evaluated the current impact of ART on the epidemiology of oropharyngeal candidiasis and antifungal resistance in these patients. Preliminary results from an ongoing clinical study showed that in patients with advanced AIDS oral yeast colonization was extensive, occurring in 81.1% of the 122 patients studied and symptomatic infection occurred in a third. In addition, resistant yeasts were still common occurring in 25.3% of patients colonized with yeasts or with symptomatic infection. Thus, oropharyngeal candidasis remains a significant infection in advanced AIDS even with ART. Current knowledge of the epidemiology, pathogenesis, clinical presentation, treatment, and mechanisms of antifungal resistance observed in oropharyngeal candidiasis are important in managing patients with this infection and are the focus of this review.

    Full Text Available INTRODUCTION: During HIV infection the severe depletion of intestinal CD4+ T-cells is associated with microbial translocation, systemic immune activation, and disease progression. This study examined intestinal and peripheral CD4+ T-cell subsets reconstitution under combined antiretroviral therapy (cART, and systemic immune activation markers. METHODS: This longitudinal single-arm pilot study evaluates CD4+ T cells, including Th1 and Th17, in gut and blood and soluble markers for inflammation in HIV-infected individuals before (M0 and after eight (M8 months of cART. From January 2010 to December 2011, 10 HIV-1 naïve patients were screened and 9 enrolled. Blood and gut CD4+ T-cells subsets and cellular immune activation were determined by flow-cytometry and plasma soluble CD14 by ELISA. CD4+ Th17 cells were detected in gut biopsies by immunohistochemistry. Microbial translocation was measured by limulus-amebocyte-lysate assay to detect bacterial lipopolysaccharide (LPS and PCR Real Time to detect plasma bacterial 16S rDNA. RESULTS: Eight months of cART increased intestinal CD4+ and Th17 cells and reduced levels of T-cell activation and proliferation. The magnitude of intestinal CD4+ T-cell reconstitution correlated with the reduction of plasma LPS. Importantly, the magnitude of Th17 cells reconstitution correlated directly with blood CD4+ T-cell recovery. CONCLUSION: Short-term antiretroviral therapy resulted in a significant increase in the levels of total and Th17 CD4+ T-cells in the gut mucosa and in decline of T-cell activation. The observation that pre-treatment levels of CD4+ and of CD8+ T-cell activation are predictors of the magnitude of Th17 cell reconstitution following cART provides further rationale for an early initiation of cART in HIV-infected individuals.

    Full Text Available Abstract Background Although severe oral opportunistic infections decreased with the implementation of highly active antiretroviral therapy, periodontitis is still a commonly described problem in patients infected with human immunodeficiency virus (HIV. The objective of the present investigation was to determine possible differences in periodontal parameters between antiretroviral treated and untreated patients. Methods The study population comprised 80 patients infected with HIV divided into two groups. The first group was receiving antiretroviral therapy while the second group was therapy naive. The following parameters were examined: probing pocket depth, gingival recession, clinical attachment level, papilla bleeding score, periodontal screening index and the index for decayed, missed and filled teeth. A questionnaire concerning oral hygiene, dental care and smoking habits was filled out by the patients. Results There were no significant differences regarding the periodontal parameters between the groups except in the clinical marker for inflammation, the papilla bleeding score, which was twice as high (P Conclusion There is no indication for advanced periodontal damage in HIV-infected versus non-infected patients in comparable age groups. Due to their immunodeficiency, HIV-infected patients should be monitored closely to prevent irreversible periodontal damage. Periodontal monitoring and early therapy is recommended independent of an indication for highly active antiretroviral therapy.

    Since the onset of the human immunodeficiency virus (HIV) epidemic, the care of infected patients improved dramatically. Whereas the disease was almost always fatal, the development of new drugs and new therapeutic strategies now allow a prolonged survival. However, the complexity of patient care is increasing and physicians face new clinical events and treatment toxicities. Recent molecules and follow-up according to the recent French recommendations will be presented here. The objectives of the treatment is to decrease mortality and morbidity of the HIV infection, by restoring near normal CD4+ T cell counts and qualitative T CD4+ responses, associated with a sustained reduction in viral replication. This objective must be reached by minimizing toxicity of antiretroviral drugs. Newly developed drugs that are better-tolerated and new therapeutic classes should improve outcome at all stages of HIV infection. Whereas viral eradication remains unrealistic and protective vaccines will not be soon available, direct consequences of long term HIV infection and issues related to an ageing HIV infected population raise up new research topics. Prevention of new infections, improvement in the precocity of care by a better-targeted screening and assessment of therapy before an established immune deficiency appear as the main priorities for the coming years.

    Little is available in scholarly literature about how HIV-positive prisoners, especially in low-income countries, access antiretroviral therapy (ART) medication. We interviewed 18 prisoners at a large prison in Namibia to identify barriers to medication adherence. The lead nurse researcher was a long-standing clinic employee at the prison, which afforded her access to the population. We identified six significant barriers to adherence, including (1) the desire for privacy and anonymity in a setting where HIV is strongly stigmatized; (2) the lack of simple supports for adherence, such as availability of clocks; (3) insufficient access to food to support the toll on the body of ingesting taxing ART medications; (4) commodification of ART medication; (5) the brutality and despair in the prison setting, generally leading to discouragement and a lack of motivation to strive for optimum health; and (6) the lack of understanding about HIV, how it is transmitted, and how it is best managed. Because most prisoners eventually transition back to communitysettings when their sentences are served, investments in prison health represent important investments in public health. PMID:24499371

    Full Text Available The introduction of highly active antiretroviral therapy (HAART has caused a marked reduction in the occurrence and severity of parasitic infections, including the toxoplasmic encephalitis (TE. These changes have been attributed to the restoration of cell-mediated immunity. This study was developed to examine the activity of six antiretroviral protease inhibitors (API on Toxoplasma gondii tachyzoites. The six API showed anti-Toxoplasma activity, with IC50 value between 1.4 and 6.6 µg/mL. Further studies at the molecular level should be performed to clarify if the use of API could be beneficial or not for AIDS patients with TE.La introducción de la terapia antirretroviral de alta efectividad ha causada una marcada reducción en la ocurrencia y curso clínico de las infecciones parasitarias, incluyendo la toxoplasmosis encefálica (TE.

    Full Text Available BACKGROUND: Substantial resources and patient commitment are required to successfully scale-up antiretroviral therapy (ART and provide appropriate HIV management in resource-limited settings. We used pharmacy refill records to evaluate risk factors for loss to follow-up (LTFU and non-adherence to ART in a large treatment cohort in Nigeria. METHODS AND FINDINGS: We reviewed clinic records of adult patients initiating ART between March 2005 and July 2006 at five health facilities. Patients were classified as LTFU if they did not return >60 days from their expected visit. Pharmacy refill rates were calculated and used to assess non-adherence. We identified risk factors associated with LTFU and non-adherence using Cox and Generalized Estimating Equation (GEE regressions, respectively. Of 5,760 patients initiating ART, 26% were LTFU. Female gender (p 350 and 2 hours to the clinic (p = 0.03, had total ART duration of >6 months (p200 at ART initiation were at a higher risk of non-adherence. Patients who disclosed their HIV status to spouse/family (p = 0.01 and were treated with tenofovir-containing regimens (p < or = 0.001 were more likely to be adherent. CONCLUSIONS: These findings formed the basis for implementing multiple pre-treatment visit preparation that promote disclosure and active community outreaching to support retention and adherence. Expansion of treatment access points of care to communities to diminish travel time may have a positive impact on adherence.

Nonadherence to antiretroviral therapy (ART is a major challenge to AIDS care, and the risks associated with it are extensive. The intention of this study was to determine prevalence and associated factors with adherence to highly active ART among people living with HIV/AIDS (PLWHA at the Debrebrihan Referral Hospital and Health Center, Northeast Ethiopia. A cross-sectional study design with systematic random sampling conducted by the use of a structured, pretested self-rating adherence questionnaire was used to conduct the study among 422 respondents from the Debrebrihan Referral Hospital and Health Center. A single population proportion formula at 95% CI with 5% of marginal error at 50% of prevalence of occurrence was used to determine sample size. Adherence was defined as not missing a single ART dose during the 30-day period prior to filling out the self-report. Adherence was measured by self-reports by the patients. These results were then used in binary logistic regression analysis. Covariates were analyzed by bivariate and multivariate logistic regression with SPSS statistical software. The total number of respondents in this study was 422; their median age was 35 years. Among the participants, 95.5% were taking their medication without missing a dose. Factors such as having emotional or practical support positively encouraged ART adherence (adjusted odds ratio 0.16 [95% CI 0.05–0.49]. However, users of traditional, complementary, and alternative medicine (TCAM (adjusted odds ratio 4.7 [95% CI 1.06–21.22] had nearly a five times higher risk for ART nonadherence (P<0.05 than those not using

    There is general consistency among US and European guidelines regarding the initiation of antiretroviral therapy for HIV-infected individuals. Recent and ongoing trials comparing regimens may lead to reevaluation of initial treatment choices. The choice of antiretroviral regimen will also likely be affected by development, evaluation, and availability of newer drugs. This article reviews currently recommended regimens and characteristics of selected current investigational drugs, including the nucleotide analogue reverse transcriptase inhibitor tenofovir alafenamide, the nonnucleoside reverse transcriptase inhibitor doravirine, the integrase strand transfer inhibitor cabotegravir, the HIV entry inhibitor BMS-663068, and the HIV maturation inhibitor BMS-955176.

    Typical progressive outer retinal necrosis (PORN) is an acute ocular infectious disease in acquired immunodeficiency syndrome (AIDS) patients with extremely low CD4+ T-cell counts. It is a form of the Varicella- zoster virus (VZV) infection. This destructive infection has an extremely rapid course that may lead to blindness in affected eyes within days or weeks. Attempts at its treatment have had limited success. We describe the case of a bilateral PORN in an AIDS patient with an initial CD4+ T-cell count >100 cells/microL that developed after initiation of highly active antiretroviral therapy (HAART). A 29-year-old Thai female initially diagnosed with human immunodeficiency virus (HIV) in 1998, presented with bilaterally decreased visual acuity after initiating HAART two months earlier. Multiple yellowish spots appeared in the deep retina without evidence of intraocular inflammation or retinal vasculitis. Her CD4+ T-cell count was 127 cells/microL. She was diagnosed as having PORN based on clinical features and positive VZV in the aqueous humor and vitreous by polymerase chain reaction (PCR). Despite combined treatment with intravenous acyclovir and intravitreous ganciclovir, the patient's visual acuity worsened with no light-perception in either eye. This case suggests that PORN should be included in the differential diagnosis of reduced visual acuity in AIDS patients initiating HAART with higher CD4+ T-cell counts. PORN may be a manifestation of the immune reconstitution syndrome.

    Full Text Available Liver disease has emerged as the most common non-AIDS-related cause of death in HIV patients. However, there is limited data regarding this condition including our setting in Ethiopia. Hence, liver enzyme abnormalities among highly active antiretroviral therapy (HAART experienced and HAART naïve patients were assessed in this study. A total of 164 HAART experienced and 164 HAART naïve patients were studied. Blood specimen was collected to determine alanine aminotransferase (ALT and aspartate aminotransferase (AST, CD4 count, and viral hepatitis. The prevalence of liver enzyme abnormality was 20.1% and 22.0% among HAART experienced and HAART naïve patients, respectively. The HAART experienced patients had higher mean ALT than HAART naïve patients (P=0.002. Viral hepatitis (AOR = 6.02; 95% CI = 1.87–19.39, opportunistic infections (AOR = 2.91; 95% CI = 1.04–8.19, current CD4 count <200 cells/mm3 (AOR = 2.16; 95% CI = 1.06–4.39, and male sex (AOR = 1.83; 95% CI = 1.001–3.33 were associated with elevated ALT and/or AST. In conclusion, liver enzyme abnormalities were high in both HAART experienced and HAART naïve HIV-1 infected patients. Hence, monitoring and management of liver enzyme abnormalities in HIV-1 infected patients are important in our setting.

    Full Text Available Highly active antiretroviral therapy (HAART has greatly improved health parameters of HIV infected individuals. However, there are several challenges associated with the chronic nature of HAART administration. For populations in health transition, dual use of medicinal plant extracts and conventional medicine poses a significant challenge. There is need to evaluate interactions between commonly used medicinal plant extracts and antiretroviral drugs used against HIV/AIDS. Efavirenz (EFV and nevirapine (NVP are the major components of HAART both metabolized by CYP2B6, an enzyme that can potentially be inhibited or induced by compounds found in medicinal plant extracts. The purpose of this study was to evaluate the effects of extracts of selected commonly used medicinal plants on CYP2B6 enzyme activity. Recombinant human CYP2B6 was used to evaluate inhibition, allowing the assessment of herb-drug interactions (HDI of medicinal plants Hyptis suaveolens, Myrothamnus flabellifolius, Launaea taraxacifolia, Boerhavia diffusa and Newbouldia laevis. The potential of these medicinal extracts to cause HDI was ranked accordingly for reversible inhibition and also classified as potential time-dependent inhibitor (TDI candidates. The most potent inhibitor for CYP2B6 was Hyptis suaveolens extract (IC50 = 19.09 ± 1.16 µg/mL, followed by Myrothamnus flabellifolius extract (IC50 = 23.66 ± 4.86 µg/mL, Launaea taraxacifolia extract (IC50 = 33.87 ± 1.54 µg/mL, and Boerhavia diffusa extract (IC50 = 34.93 ± 1.06 µg/mL. Newbouldia laevis extract, however, exhibited weak inhibitory effects (IC50 = 100 ± 8.71 µg/mL on CYP2B6. Launaea taraxacifolia exhibited a TDI (3.17 effect on CYP2B6 and showed a high concentration of known CYP450 inhibitory phenolic compounds, chlorogenic acid and caffeic acid. The implication for these observations is that drugs that are metabolized by CYP2B6 when co-administered with these herbal medicines and when adequate amounts of the

    Full Text Available Few studies have documented the contribution of HIV/AIDS to mortality among children under 15 years. From June 30 to October 19, 2001, all child deaths (n=588 registered to the morgue and/or hospitals of the city of Pointe-Noire, Congo, were investigated using a combined approach including an interview of relatives and postmortem clinical and biological HIV diagnosis. Twenty-one percent of children were HIV positive, while 10.5% of deaths were attributed to AIDS. The most common causes of death in HIV-infected children were pneumonia (30%, pyrexia (22%, diarrhoea (16% and wasting syndrome (16%. Infant mortality rate was estimated 6.3 times higher in children born to HIV-infected mothers compared to HIV-uninfected mothers. This study provides a direct measure of HIV/AIDS as impact on child mortality using a rapid and reliable method. A significant number of deaths could be prevented if HIV infection was diagnosed earlier and infants were provided with antiretroviral treatments.

    Both naïve CD4+ and naïve CD8+ T cells are depleted in individuals with human immunodeficiency virus type 1 (HIV-1) infection by unknown mechanisms. Analysis of their dynamics prior to and after highly active antiretroviral therapy (HAART) could reveal possible mechanisms of depletion. Twenty patients were evaluated with immunophenotyping, intracellular Ki67 staining, T-cell receptor excision circle (TREC) quantitation in sorted CD4 and CD8 cells, and thymic computed tomography scans prior to and ∼6 and ∼18 months after initiation of HAART. Naïve T-cell proliferation decreased significantly during the first 6 months of therapy (P < 0.01) followed by a slower decline. Thymic indices did not change significantly over time. At baseline, naïve CD4+ T-cell numbers were lower than naive CD8+ T-cell numbers; after HAART, a greater increase in naïve CD4+ T cells than naïve CD8+ T cells was observed. A greater relative change (n-fold) in the number of TREC+ T cells/μl than in naïve T-cell counts was observed at 6 months for both CD4+ (median relative change [n-fold] of 2.2 and 1.7, respectively; P < 0.01) and CD8+ T cell pools (1.4 and 1.2; P < 0.01). A more pronounced decrease in the proliferation than the disappearance rate of naïve T cells after HAART was observed in a second group of six HIV-1-infected patients studied by in vivo pulse labeling with bromodeoxyuridine. These observations are consistent with a mathematical model where the HIV-1-induced increase in proliferation of naïve T cells is mostly explained by a faster recruitment into memory cells.

    Background Few studies have examined the properties of human immunodeficiency virus type 1 (HIV-1) epitope-specific cytotoxic T lymphocyte (CTL) responses in children. To address this issue, we characterized epitope-specific CTL responses and analyzed the determinants that may affect CTL responses before and after highly active antiretroviral therapy (HAART) in children with HIV-1 infection.Methods A total of 22 HIV-1-infected children and 23 uninfected healthy children as control were enrolled in the study. Circulating CD4 T cells and HIV-1 RNA load in plasma were routinely measured. Peripheral HIV-1-specific CTL frequency and HIV-1 epitope-specific, interferon-γ (IFN-γ)-producing T lymphocytes were measured using tetramer staining and enzyme-linked immunospot (ELISPOT) assay, respectively.Circulating dendritic cell (DC) subsets were monitored with FACS analysis.Results More than 80% of the children with HIV-1 infection exhibited a positive HIV-1-epitope-specific CTL response at baseline, but HIV-specific CTLs and IFN-γ-producing lymphocytes decreased in patients who responded to HAART in comparison with non-responders and HAART-naive children. The duration of virus suppression resulted from HAART was inversely correlated with CTL frequency. While in HAART-naive children, HIV-1-specific CTL frequency was positively correlated with myeloid DC (mDC) frequency,although the cause and effect relationship between the DCs and CTLs remains unknown.Conclusions HIV-1-epitope-specific CTL responses are dependent on antigenic stimulation. The impaired DC subsets in blood might result in a defect in DC-mediated T cell responses. These findings may provide insight into understanding the factors and related mechanisms that influence the outcome of HIV-1 carriers to HAART or future antiviral therapies.

    Author Summary Over the two decades highly active antiretroviral therapy (HAART) for the treatment of HIV infection has led to a significant decline in morbidity and mortality rates among HIV-infected individuals. HAART uses a combination of molecules that target the virus itself. However, naturally occurring and extensive genetic variation found in the virus allow the emergence of drug-resistant viruses, which rapidly render individuals untreatable. An alternative approach for effective anti...

    BACKGROUND: Pregnancy has been associated with a decreased risk of HIV disease progression in the highly active antiretroviral therapy (HAART) era. The effect of timing of HAART initiation relative to pregnancy on maternal virologic, immunologic and clinical outcomes has not been assessed. METHODS: We conducted a retrospective cohort study from 1997-2005 among 112 pregnant HIV-infected women who started HAART before (N = 12), during (N = 70) or after pregnancy (N = 30). RESULTS: Women initiat...

    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

    Full Text Available A low CD4/CD8 ratio in elderly HIV-uninfected adults is associated with increased morbidity and mortality. A subset of HIV-infected adults receiving effective antiretroviral therapy (ART fails to normalize this ratio, even after they achieve normal CD4+ T cell counts. The immunologic and clinical characteristics of this clinical phenotype remain undefined. Using data from four distinct clinical cohorts and three clinical trials, we show that a low CD4/CD8 ratio in HIV-infected adults during otherwise effective ART (after CD4 count recovery above 500 cells/mm3 is associated with a number of immunological abnormalities, including a skewed T cell phenotype from naïve toward terminally differentiated CD8+ T cells, higher levels of CD8+ T cell activation (HLADR+CD38+ and senescence (CD28- and CD57+CD28-, and higher kynurenine/tryptophan ratio. Changes in the peripheral CD4/CD8 ratio are also reflective of changes in gut mucosa, but not in lymph nodes. In a longitudinal study, individuals who initiated ART within six months of infection had greater CD4/CD8 ratio increase compared to later initiators (>2 years. After controlling for age, gender, ART duration, nadir and CD4 count, the CD4/CD8 ratio predicted increased risk of morbidity and mortality. Hence, a persistently low CD4/CD8 ratio during otherwise effective ART is associated with increased innate and adaptive immune activation, an immunosenescent phenotype, and higher risk of morbidity/mortality. This ratio may prove useful in monitoring response to ART and could identify a unique subset of individuals needed of novel therapeutic interventions.

    Full Text Available Millions of HIV-infected Africans are living longer due to long-term antiretroviral therapy (ART, yet little is known about glucose metabolism disorders in this group. We aimed to compare the prevalence of glucose metabolism disorders among HIV-infected adults on long-term ART to ART-naïve adults and HIV-negative controls, hypothesizing that the odds of glucose metabolism disorders would be 2-fold greater even after adjusting for possible confounders.In this cross-sectional study conducted between October 2012 and April 2013, consecutive adults (>18 years attending an HIV clinic in Tanzania were enrolled in 3 groups: 153 HIV-negative controls, 151 HIV-infected, ART-naïve, and 150 HIV-infected on ART for ≥ 2 years. The primary outcome was the prevalence of glucose metabolism disorders as determined by oral glucose tolerance testing. We compared glucose metabolism disorder prevalence between each HIV group vs. the control group by Fisher's exact test and used multivariable logistic regression to determine factors associated with glucose metabolism disorders.HIV-infected adults on ART had a higher prevalence of glucose metabolism disorders (49/150 (32.7% vs.11/153 (7.2%, p<0.001 and frank diabetes mellitus (27/150 (18.0% vs. 8/153 (5.2%, p = 0.001 than HIV-negative adults, which remained highly significant even after adjusting for age, gender, adiposity and socioeconomic status (OR = 5.72 (2.78-11.77, p<0.001. Glucose metabolism disorders were significantly associated with higher CD4+ T-cell counts. Awareness of diabetes mellitus was <25%.HIV-infected adults on long-term ART had 5-fold greater odds of glucose metabolism disorders than HIV-negative controls but were rarely aware of their diagnosis. Intensive glucose metabolism disorder screening and education are needed in HIV clinics in sub-Saharan Africa. Further research should determine how glucose metabolism disorders might be related to immune reconstitution.

    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

    One to two million people worldwide are infected with the human immunodeficiency virus type 2 (HIV-2), with highest prevalences in West African countries, but also present in Western Europe, Asia and North America. Compared to HIV-1, HIV-2 infection undergoes a longer asymptomatic phase and progresses to AIDS more slowly. In addition, HIV-2 shows lower transmission rates, probably due to its lower viremia in infected individuals. There is limited experience in the treatment of HIV-2 infection and several antiretroviral drugs used to fight HIV-1 are not effective against HIV-2. Effective drugs against HIV-2 include nucleoside analogue reverse transcriptase (RT) inhibitors (e.g. zidovudine, tenofovir, lamivudine, emtricitabine, abacavir, stavudine and didanosine), protease inhibitors (saquinavir, lopinavir and darunavir), and integrase inhibitors (raltegravir, elvitegravir and dolutegravir). Maraviroc, a CCR5 antagonist blocking coreceptor binding during HIV entry, is active in vitro against CCR5-tropic HIV-2 but more studies are needed to validate its use in therapeutic treatments against HIV-2 infection. HIV-2 strains are naturally resistant to a few antiretroviral drugs developed to suppress HIV-1 propagation such as nonnucleoside RT inhibitors, several protease inhibitors and the fusion inhibitor enfuvirtide. Resistance selection in HIV-2 appears to be faster than in HIV-1. In this scenario, the development of novel drugs specific for HIV-2 is an important priority. In this review, we discuss current anti-HIV-2 therapies and mutational pathways leading to drug resistance. PMID:24345729

    Full Text Available We report a case of Strongyloides stercoralis hyperinfection syndrome with central nervous system involvement, in a patient with late human immunodeficiency virus (HIV infection starting antiretroviral therapy, in whom Strongyloides stercoralis larvae and Cryptococcus neoformans were isolated antemortem from cerebrospinal fluid. Our patient was not from an endemic region for the parasite, so strongyloidiasis was not originally suspected. For this reason, we conclude that Strongyloides stercoralis infection should be suspected in HIV-infected patients starting antiretroviral therapy in order to avoid potential fatal outcomes.

    Objectives Human herpesviruses (HHVs), e.g. herpes simplex virus (HSV) type 1, Epstein-Barr virus and cytomegalovirus, appear in saliva at greater frequency in persons infected with human immunodeficiency virus (HIV) than healthy individuals. However, it is not known if varicella zoster virus (VZV) and HSV-2 appear simultaneously during HIV infection at greater frequency in saliva during this era of highly active antiretroviral therapy (HAART). The aim of this study was to investigate the prevalence and amounts of VZV and HSV-2 in the saliva of HIV-infected, orally asymptomatic patients. Study Design Quantitative polymerase chain reaction was used to investigate the prevalence, quantity, risk, and correlates of salivary VZV and HSV-2 from 59 HIV-seropositive individuals and 53 healthy controls in a case-control, cross-sectional study. Seventy-eight percent of the HIV-seropositive patients (46/59) were taking HAART. Results VZV DNA was detected in the saliva of 5.1% (3/59) of the HIV-positive group and in only one healthy control 1.9% (1/53; P = 0.62). The amount of VZV DNA in the expressors was low, generally less than 1,100 copies/mL with no observed difference between the HIV-positive group and the controls (P= 1.0). HSV-2 DNA was not detected in either group. In the HIV-infected group, VZV shedding occurred in those on HAART, but was not associated with oral lesions, specific CD4+ or CD8+ T-cell levels, or demographic factors. Conclusions VZV was detected at low prevalence in the saliva of HIV-infected persons whereas HSV-2 was not detected in the saliva of this cohort. HAART does not appear to diminish the risk for asymptomatic VZV shedding. PMID:20123407

    Full Text Available Highly active antiretroviral therapy (HAART is used in patients infected with HIV. This treatment has been shown to significantly decrease opportunist infections such as those caused by viruses, fungi and particularly, protozoa. The use of HAART in HIV-positive persons is associated with immune reconstitution as well as decreased prevalence of oral candidiasis and candidal carriage. Antiretroviral therapy benefits patients who are co-infected by the human immunodeficiency virus (HIV, human herpes virus 8 (HHV-8, Epstein-Barr virus, hepatitis B virus (HBV, parvovirus B19 and cytomegalovirus (CMV. HAART has also led to a significant reduction in the incidence, and the modification of characteristics, of bacteremia by etiological agents such as Staphylococcus aureus, coagulase negative staphylococcus, non-typhoid species of Salmonella, Streptococcus pneumoniae, Pseudomonas aeruginosa, and Mycobacterium tuberculosis. HAART can modify the natural history of cryptosporidiosis and microsporidiosis, and restore mucosal immunity, leading to the eradication of Cryptosporidium parvum. A similar restoration of immune response occurs in infections by Toxoplasma gondii. The decline in the incidence of visceral leishmaniasis/HIV co-infection can be observed after the introduction of protease inhibitor therapy. Current findings are highly relevant for clinical medicine and may serve to reduce the number of prescribed drugs thereby improving the quality of life of patients with opportunistic diseases.A terapia HAART (terapia antirretroviral altamente ativa é usada em pacientes infectados pelo vírus da imunodeficiência humana (HIV e demonstrou diminuição significativa de infecções oportunistas, tais como as causadas por vírus, fungos, protozoários e bactérias.

    Full Text Available Abstract Introduction The availability of raltegravir plus atazanavir provides an alternative antiretroviral strategy that may be equally efficacious and less toxic than those currently recommended in HIV treatment guidelines. In fact, this new combination antiretroviral therapy attracts the attention of the scientific community because both drugs have a good safety profile coupled with potent antiviral activity, and their combined use would avert nucleoside- and ritonavir-related toxicities. Case presentation We describe the case of a 47-year-old, Caucasian woman treated for HIV-1 infection who developed Buffalo Hump during antiretroviral therapy, including raltegravir and unboosted atazanavir. Clinical evaluation and an ultrasonography scan of the cervical region showed a new progressive increase of lipohypertrophy and the results of DEXA confirmed these data. In our patient the worsening of the Buffalo Hump cannot be attributed to hypercortisolism; insulin-resistance, diabetes, dyslipidemia, hyperlactatemia and metabolic syndrome were not present. Moreover, she was not in therapy with antiretroviral drugs that are described as the cause of Buffalo Hump; on the other hand she developed this side effect three months after the switch of the antiretroviral therapy to raltegravir plus unboosted atazanavir. Conclusion Current data indicate that the etiology of HIV-associated Buffalo Hump remains elusive but is likely multifactorial; a possible contributing cause, but not the main cause, could be exposure to antiretroviral drugs. To the best of our knowledge, this is the first report on development of Buffalo Hump in the course of antiretroviral therapy, including the use of these drugs. On the basis of our data we can formulate the hypothesis of a pharmacological pathogenesis that underlies the development of this case of Buffalo Hump in the absence of other risk factors.

    Background CD4~+ T cell counts have been used as the indicator of human immunodeficiency virus type 1 (HIV-1) disease progression and thereby to determine when to start highly active antiretroviral therapy (HAART). Whether and how the baseline CD4~+T cell count affects the immunological and viral responses or adverse reactions to nevirapine (NVP)-containing HAART in Chinese HIV-1 infected adults remain to be characterized.Methods One hundred and ninety-eight HIV-seropositive antiretroviral therapy (ART)-naive subjects were enrolled into a prospective study from 2005 to 2007. Data were analyzed by groups based on baseline CD4~+T cell counts either between 100-200 cells/μl or 201-350 cells/pl. Viral responses, immunologic responses and adverse events were monitored at baseline and at weeks 4, 12, 24, 36, 52, 68, 84, 100.Results Eighty-six and 112 subjects ranged their CD4~+T cell counts 100-200 cells/μl and 201-350 cells/μl, respectively.The pre-HAART viral load in CD4 201-350 cells/μl group was significantly lower than that in CD4 100-200 cells/μl group (P=0.000). After treatment, no significant differences were observed between these two groups either in the plasma viral load (pVL) or in the viral response rate calculated as the percentage of pVL less than 50 copies/μl or less than 400 copies/ml. The CD4~+T cell counts were statistically higher in the 201-350 group during the entire follow-ups (P<0.01) though CD4~+ T cell count increases were similar in these two groups. After 100-week treatment, the median of CD4~+ T cell counts were increased to 331 cells/μl for CD4 100-200 cells/μl group and to 462 cells/μl for CD4 201-350 cells/μl group.Only a slightly higher incidence of nausea was observed in CD4 201-350 cells/μl group (P=0.05) among all adverse reactions, including rash and liver function abnormality.Conclusions The pVLs and viral response rates are unlikely to be associated with the baseline CD4~+T cell counts.

    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

  14. Small-molecule inhibition of HIV pre-mRNA splicing as a novel antiretroviral therapy to overcome drug resistance.

    2007-10-01

    Full Text Available The development of multidrug-resistant viruses compromises antiretroviral therapy efficacy and limits therapeutic options. Therefore, it is an ongoing task to identify new targets for antiretroviral therapy and to develop new drugs. Here, we show that an indole derivative (IDC16 that interferes with exonic splicing enhancer activity of the SR protein splicing factor SF2/ASF suppresses the production of key viral proteins, thereby compromising subsequent synthesis of full-length HIV-1 pre-mRNA and assembly of infectious particles. IDC16 inhibits replication of macrophage- and T cell-tropic laboratory strains, clinical isolates, and strains with high-level resistance to inhibitors of viral protease and reverse transcriptase. Importantly, drug treatment of primary blood cells did not alter splicing profiles of endogenous genes involved in cell cycle transition and apoptosis. Thus, human splicing factors represent novel and promising drug targets for the development of antiretroviral therapies, particularly for the inhibition of multidrug-resistant viruses.

    Full Text Available Pharmacist’s interventions (also known as pharmaceutical care plans are means of solving the drug therapy problems identified in pharmaceutical care. Outcomes are the results of pharmacists’ intervention activities. Patients’ satisfaction refers to patients’ feeling of fulfillment, pleasure or happiness with the services they have received. This study was designed to determine the types of pharmacist interventions applied in the pharmaceutical care of HIV patients receiving treatment at a tertiary hospital in southeast Nigeria, the types of outcomes of such interventions and level of patients’ satisfaction with their drug therapy. The components of the American society of health-system pharmacists (ASHP guidelines on ‘standardized method for pharmaceutical care was used as a data collection instrument to evaluate, document and intervene in the antiretroviral therapy of about one thousand four hundred and seventy three (1,473 patients. The results showed significant reductions in the frequency of the various interventions and parameters measured after the interventions. The study concluded that pharmaceutical interventions influences patients’ adherence, optimizes their drug therapy and improves rational prescribing and care resulting in significant improvements in the outcomes of their treatment and levels of satisfaction.

    2000-01-01

    Interferons play an important, but incompletely understood role in HIV-related disease. We investigated the effect of HAART on plasma levels of IFN-alpha, IFN-gamma, neopterin and interferon-inducible protein 10 (IP-10) in 41 HIV-infected patients during 78 weeks of therapy. At baseline HIV......-infected patients had raised levels of both IP-10 and IFN-alpha compared with healthy controls (n = 19), with particularly high levels in advanced disease. HAART induced a marked decrease in levels of both IFN-alpha, neopterin and IP-10, though not to normal concentrations. In contrast, IFN-gamma levels were low...... throughout the study, and not different from controls. While neopterin and IP-10 remained significantly decreased compared with baseline levels throughout the study, IFN-alpha levels returned to baseline at the end of the study. Persistently high IP-10 and IFN-alpha levels were associated with immunological...

    OBJECTIVE: To estimate the extent of drug resistance accumulation in patients kept on a virologically failing regimen and its determinants in the clinical setting. DESIGN: The study focused on 110 patients of EuroSIDA on an unchanged regimen who had two genotypic tests performed at two time points...... (t0 and t1) when viral load was > 400 copies/ml. METHODS: Accumulation of resistance between t0 and t1 was measured using genotypic susceptibility scores (GSS) obtained by counting the total number of active drugs (according to the Rega system v6.4.1) among all licensed antiretrovirals as of 1...... January 2006. Patients were grouped according to the number of active drugs in the failing regimen at t0 (GSS_f-t0). RESULTS: At t0, patients had been on the failing combination antiretroviral therapy (cART) for a median of 11 months (range, 6-50 months). Even patients with extensive resistance...

  18. Do disability grants influence adherence to antiretroviral therapy?

    Directory of Open Access Journals (Sweden)

    Ashraf Kagee

    2014-04-01

    Full Text Available Anecdotal data suggest that some South Africans living with HIV who receive disability grants from the state deliberately default on their antiretroviral medication in an attempt to lower their CD4 count to remain eligible for grants. No actual empirical data however exist to show that disability grants act as such perverse incentives and are a valid reason for non-adherence. This article examines some of the complexities of antiretroviral adherence in the context of a resource-constrained environment. The multitude of structural barriers, including sometimes difficult patient-doctor conversations about the renewal of disability grants, shape patients’ experiences of the clinic environment and influence their adherence to care.

    Background Liver injury is one of the most important adverse effects of antiretroviral therapy, leading to therapy changing or discontinuation. Data on liver injury in human immunodeficiency virus-1-infected patients receiving antiretroviral therapy are limited in China. The purpose of this study was to investigate the features of liver injury in human immunodeficiency virus type 1-infected patients receiving non-nucleosides reverse transcriptase inhibitors-based antiretroviral therapy in China.Methods Seventy-five patients on antiretroviral therapy containing non-nucleosides reverse transcriptase inhibitors were retrospectively studied. The patients were divided into 2 groups: group 1 (with liver injury, n=45) and group 2(without liver injury, n=30). The features of liver injury were analyzed. The sex, age, baseline CD4 counts, hepatitis B virus (HBV) and/or hepatitis C virus (HCV) co-infection, hepatotoxic drug use and nevirapine or efavirenz use were compared between two groups.Results Forty-five patients (60.0%), 31 (68.9%) males and 14 (31.1%) females, aged 12 to 52 years (averaged (3g±9)years), experienced at least one episode of liver injury. Forty (53.3%) patients were co-infected with HBV and/or HCV, 42 (56%) patients had concomitant use of antituberculosis drugs or cotrimoxazole, 46 (61.3%) and 29 (38.7%) patients received regimen containing nevirapine and efavirenz, respectively. Grade 1 liver injuries were observed in 26 (57.8%)patients, grade 2 in 16 (35.6%), grade 3 in 2 (4.0%) and grade 4 in 1 (2.2%). Three (6.7%) patients discontinued highly active antiretroviral therapy (HAART) due to liver injury. In group 1, there were 29 (64.4%) patients co-infected with HBV and/or HCV, 32 (71.1%) patients received regimen containing nevirapine, and 30 (66.7%) patients had concomitant use of anti-tuberculosis drugs or cotrimoxazole, respectively, significantly higher than those in group 2 (11 (36.7%), 14 (46.7%)and 12 (40%), respectively; P=0.018, 0.033, 0

  20. Predictors of attrition and immunological failure in HIV-1 patients on highly active antiretroviral therapy from different healthcare settings in Mozambique.

    Claudia Palladino

    Full Text Available In Mozambique, the evaluation of retention in HIV care and ART programmes is limited. To assess rate and predictors of attrition (no retention in care and HAART effectiveness in HIV-1 infected patients who pay for medication and laboratory testing in Mozambique, we conducted a multicenter survey of HIV-1-infected patients who started HAART during 2002-2006. Cox proportional hazard models were used to assess risk of attrition and of therapy failure. Overall, 142 patients from 16 healthcare centers located in the capital city Maputo were followed-up for 22.2 months (12.1-46.7. The retention rate was 75%, 48% and 37% after one, two and three years, respectively. Risk of attrition was lower in patients with higher baseline CD4 count (P = 0.022 and attending healthcare center 1 (HCC1 (P = 0.013. The proportion of individuals with CD4 count ≤ 200 cells/µL was 55% (78/142 at baseline and decreased to 6% (3/52 at 36 months. Among the patients with available VL, 86% (64/74 achieved undetectable VL levels. The rate of immunologic failure was 17.2% (95% CI: 12.6-22.9 per 100 person-years. Risk of failure was associated to higher baseline CD4 count (P = 0.002, likely reflecting low adherence levels, and decreased with baseline VL ≥ 10,000 copies/mL (P = 0.033. These results suggest that HAART can be effective in HIV-1 infected patients from Mozambique that pay for their medication and laboratory testing. Further studies are required to identify the causes for low retention rates in patients with low CD4 counts and to better understand the association between healthcare setting and attrition rate.

    Full Text Available Introduction Even with current highly active antiretroviral therapy, individuals with AIDS continue to exhibit important nutritional deficits and reduced levels of albumin and hemoglobin, which may be directly related to their cluster of differentiation 4 (CD4 cell counts. The aim of this study was to characterize the nutritional status of individuals with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS and relate the findings to the albumin level, hemoglobin level and CD4 cell count. Methods Patients over 20 years of age with AIDS who were hospitalized in a university hospital and were receiving antiretroviral therapy were studied with regard to clinical, anthropometric, biochemical and sociodemographic characteristics. Body mass index, percentage of weight loss, arm circumference, triceps skinfold and arm muscle circumference were analyzed. Data on albumin, hemoglobin, hematocrit and CD4 cell count were obtained from patient charts. Statistical analysis was performed using Fisher's exact test, Student's t-test for independent variables and the Mann-Whitney U-test. The level of significance was set to 0.05 (α = 5%. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS 17.0 software for Windows. Results Of the 50 patients evaluated, 70% were male. The prevalence of malnutrition was higher when the definition was based on arm circumference and triceps skinfold measurement. The concentrations of all biochemical variables were significantly lower among patients with a body mass index of less than 18.5kg/m2. The CD4 cell count, albumin, hemoglobin and hematocrit anthropometric measures were directly related to each other. Conclusions These findings underscore the importance of nutritional follow-up for underweight patients with AIDS, as nutritional status proved to be related to important biochemical alterations.

    Background The frequencies of regulatory T cells (Tregs) increased over the HIV infection but its counts actually decreased. We proposed that the decrease of Treg counts may cause the reduction of inhibitory effect and thereby account for the over-activation of Tregs during HIV infection. However, it remains unknown whether Tregs are also over-activated and thereafter the activation induced death may lead to the decrease of Tregs. Methods Tregs were defined as CD4+CD25+CD127lo/-T cells. Eighty-one HIV-1 infected patients were enrolled in our study, and twenty-two HIV-1 seronegative donors were recruited as the control. The levels of HLA-DR on Tregs were determined by FACSAria flow cytometer. ResultsCompared to HIV-1 seronegative donors, the levels of HLA-DR on CD4+CD25+CD127lo/- Tregs were significantly increased in HIV-1 infected patients, and its increase was positively associated with viral loads (r=0.3163,P=0.004) and negatively with CD4 T-cell counts (r=-0.4153, P<0.0001). In addition, significant associations between HLA-DR expression on CD4+CD25+CD127lo/-Tregs and the percentages of HLA-DR, CD38, Ki67 expressing CD4+ and CD8+ T cells were also identified. Conclusion HLA-DR on Tregs is a good marker for viral replication and disease progression. The over-activation of Tregs might result in the decrease of Tregs.

  8. French 2013 guidelines for antiretroviral therapy of HIV-1 infection in adults

    Full Text Available Introduction: These guidelines are part of the French Experts’ recommendations for the management of people living with HIV/AIDS, which were made public and submitted to the French health authorities in September 2013. The objective was to provide updated recommendations for antiretroviral treatment (ART of HIV-positive adults. Guidelines included the following topics: when to start, what to start, specific situations for the choice of the first session of antiretroviral therapy, optimization of antiretroviral therapy after virologic suppression, and management of virologic failure. Methods: Ten members of the French HIV 2013 expert group were responsible for guidelines on ART. They systematically reviewed the most recent literature. The chairman of the subgroup was responsible for drafting the guidelines, which were subsequently discussed within, and finalized by the whole expert group to obtain a consensus. Recommendations were graded for strength and level of evidence using predefined criteria. Economic considerations were part of the decision-making process for selecting preferred first-line options. Potential conflicts of interest were actively managed throughout the whole process. Results: ART should be initiated in any HIV-positive person, whatever his/her CD4 T-cell count, even when >500/mm3. The level of evidence of the individual benefit of ART in terms of mortality or progression to AIDS increases with decreasing CD4 cell count. Preferred initial regimens include two nucleoside reverse transcriptase inhibitors (tenofovir/emtricitabine or abacavir/lamivudine plus a non-nucleoside reverse transcriptase inhibitor (efavirenz or rilpivirine, or a ritonavir-boosted protease inhibitor (atazanavir or darunavir. Raltegravir, lopinavir/r, and nevirapine are recommended as alternative third agents, with specific indications and restrictions. Specific situations such as HIV infection in women, primary HIV infection, severe immune suppression

    Full Text Available Objectives: To estimate the percentage of adherence to highly-active antiretroviral therapy (HAART in Spanish observational studies and to identify the variables associated with adherence. Methods: Seven electronic databases were used to locate the studies. Six inclusion criteria were established. Two coders codified the variables independently. Intercoder reliability was calculated. Publication bias was analyzed through the Begg, Egger and Trim and Fill tests. Homogeneity was evaluated using the Q test and the l² index. A random effects model was assumed to estimate both the overall percentage of adherence and to explain heterogeneity. Results: This meta-analysis included 23 observational studies, yielding a total of 34 adherence estimates. The sample was composed of 9,931 HIV-positive individuals (72% men older than 18 years under treatment with HAART. The percentage of patients adhering to an intake of >90% of the prescribed antiretroviral drugs was 55%. Wide heterogeneity was detected (I²=91.20; 95%CI: 88.75-93.13. Adherence was mainly measured using a single strategy (47.8%, the most widely used being self-report (48.7%. In the univariate analysis, the following factors were significant: infection stages A (β=0.68, p 200 copies/ml (β=-0.41, p Objetivo: Calcular el porcentaje de adherencia al TARGA en estudios observacionales españoles, así como identificar las variables asociadas a ella.

    Thiosemicarbazones display a wide antimicrobial activity by targeting bacteria, fungi, and viruses. Here, we report our studies on the antiviral activity of two thiosemicarbazone metal complexes, [bis(citronellalthiosemicarbazonato)nickel(II)] and [aqua(pyridoxalthiosemicarbazonato)copper(II)] chloride monohydrate, against the retroviruses HIV-1 and HTLV-1/-2. Both compounds exhibit antiviral properties against HIV but not against HTLVs . In particular, the copper complex shows the most potent anti-HIV activity by acting at the post-entry steps of the viral cycle. PMID:21121632

    Full Text Available Abstract Background This trial aims at testing the efficacy of weekly reminder and motivational text messages, compared to usual care in improving adherence to Highly Active Antiretroviral Treatment in patients attending a clinic in Yaoundé, Cameroon. Methods and Design This is a single-centered randomized controlled single-blinded trial. A central computer generated randomization list will be generated using random block sizes. Allocation will be determined by sequentially numbered sealed opaque envelopes. 198 participants will either receive the mobile phone text message or usual care. Our hypothesis is that weekly motivational text messages can improve adherence to Highly Active Antiretroviral Treatment and other clinical outcomes in the control group by acting as a reminder, a cue to action and opening communication channels. Data will be collected at baseline, three months and six months. A blinded program secretary will send out text messages and record delivery. Our primary outcomes are adherence measured by the visual analogue scale, self report, and pharmacy refill data. Our secondary outcomes are clinical: weight, body mass index, opportunistic infections, all cause mortality and retention; biological: Cluster Designation 4 count and viral load; and quality of life. Analysis will be by intention-to-treat. Covariates and subgroups will be taken into account. Discussion This trial investigates the potential of SMS motivational reminders to improve adherence to Highly Active Antiretroviral Treatment in Cameroon. The intervention targets non-adherence due to forgetfulness and other forms of non-adherence.

  15. Antiretroviral Therapy for HIV-2 Infection: Recommendations for Management in Low-Resource Settings

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available HIV-2 contributes approximately a third to the prevalence of HIV in West Africa and is present in significant amounts in several low-income countries outside of West Africa with historical ties to Portugal. It complicates HIV diagnosis, requiring more expensive and technically demanding testing algorithms. Natural polymorphisms and patterns in the development of resistance to antiretrovirals are reviewed, along with their implications for antiretroviral therapy. Nonnucleoside reverse transcriptase inhibitors, crucial in standard first-line regimens for HIV-1 in many low-income settings, have no effect on HIV-2. Nucleoside analogues alone are not sufficiently potent enough to achieve durable virologic control. Some protease inhibitors, in particular those without ritonavir boosting, are not sufficiently effective against HIV-2. Following review of the available evidence and taking the structure and challenges of antiretroviral care in West Africa into consideration, the authors make recommendations and highlight the needs of special populations.

    High mortality rates have been reported in the first 90 days of antiretroviral therapy in Zambia and other low-income countries. We report a case of acute hypophosphataemia and hypokalaemia in the first week of antiretroviral therapy in a patient with extreme AIDS wasting. Given its occurrence in an extremely wasted patient, it may be physiologically similar to refeeding syndrome but other causes could be relevant as well. Acute hypophosphataemia may contribute to early antiretroviral therapy associated mortality in low-income countries.

    Full Text Available A terapia anti-retroviral altamente ativa, usada contra o Vírus da Imunodeficiência Humana, vem possibilitando a melhora do quadro clínico-laboratorial de portadores da Síndrome da Imunodeficiência Adquirida. Contudo, alterações metabólicas e complicações morfológicas, associadas ao uso da terapia, vêm sendo investigadas. A utilização prolongada desta terapia tem um impacto importante sobre o estado nutricional dos pacientes. Antes da sua utilização, a perda de peso e a desnutrição, conseqüências das infecções oportunistas, eram os maiores problemas nutricionais. Atualmente, o foco principal das discussões têm sido as complicações metabólicas e morfológicas, dentre elas a lipodistrofia, com a dislipidemia, a resistência à insulina, a osteopenia, e a distribuição alterada da gordura corporal, aumentando assim os riscos de doenças cardiovasculares. A nutrição desempenha um papel fundamental no suporte da saúde desses pacientes, integrando as equipes multiprofissionais, promovendo a melhora da adesão à terapia anti-retroviral e do prognóstico da doença. No entanto, para que se tenha mais conhecimento sobre a terapia, as proporções de seus efeitos adversos, e o perfil nutricional desses pacientes, a curto e a longo prazos, é de suma importância que se estude mais sobre este assunto, a fim de permitir perspectivas de um regime terapêutico mais seguro dentro de seus alcances metodológicos, proporcionando uma melhor qualidade de vida aos pacientes.The highly active antiretroviral therapy used against Human Immunodeficiency Virus provides an improvement in laboratory and clinical findings of patients with Acquired Immunodeficiency Syndrome.

    Full Text Available Highly active antiretroviral therapy (HAART has been associated with dysglycaemia. However, there is scarce data on the risk of developing diabetes mellitus (DM in HIV/AIDS patients in Africa.Primarily to quantify and compare the risk of having diabetes mellitus in HIV/AIDS patients on HAART and HAART-naïve patients in Limbe, Cameroon; and secondarily to determine if there is an association between HAART and increased DM risk.A cross-sectional study was conducted at the Limbe Regional Hospital HIV treatment center between April and June 2013, involving 200 HIV/AIDS patients (100 on first-line HAART regimens for at least 12 months matched by age and gender to 100 HAART-naïve patients. The Diabetes Risk Score (DRS was calculated using a clinically validated model based on routinely recorded primary care parameters. A DRS ≥ 7% was considered as indicative of an increased risk of developing DM.The median DRS was significantly higher in patients on HAART (2.30% than in HAART-naïve patients (1.62%, p = 0.002. The prevalence of the increased DM risk (DRS ≥ 7% was significantly higher in patients on HAART, 31% (95% CI: 22.13-41.03 than in HAART-naïve patients, 17% (95% CI: 10.23-25.82, p = 0.020. HAART was significantly associated with an increased DM risk, the odds ratio of the HAART group compared to the HAART-naïve group was 2.19 (95% CI: 1.12-4.30, p = 0.020. However, no association was found after adjusting for BMI-defined overweight, hypertension, age, sex, family history of DM and smoking (Odds ratio = 1.22, 95% CI: 0.42-3.59, p = 0.708. Higher BMI and hypertension accounted for the increased risk of DM in patients on HAART. Also, more than 82% of the participants were receiving or had ever used Zidovudine based HAART regimens.HIV/AIDS patients on HAART could be at a greater risk of having DM than HAART-naïve patients as a result of the effect of HAART on risk factors of DM such as BMI and blood pressure.

  20. KIR-HLA genotypes in HIV-infected patients lacking immunological recovery despite effective antiretroviral therapy.

    Directory of Open Access Journals (Sweden)

    Alessandro Soria

    Full Text Available BACKGROUND: In HIV-infected individuals, mechanisms underlying unsatisfactory immune recovery during effective combination antiretroviral therapy (cART have yet to be fully understood. We investigated whether polymorphism of genes encoding immune-regulating molecules, such as killer immunoglobulin-like receptors (KIR and their ligands class I human leukocyte antigen (HLA, could influence immunological response to cART. METHODS: KIR and HLA frequencies were analyzed in 154 HIV-infected and cART-treated patients with undetectable viral load divided into two groups: 'immunological non responders' (INR, N = 50, CD4(+ T-cell count 350/mm(3. Molecular KIR were typed using polymerase chain reaction-based genotyping. Comparisons were adjusted for baseline patient characteristics. RESULTS: The frequency of KIR2DL3 allele was significantly higher in FR than in INR (83.7% vs. 62%, P = 0.005. The functional compound genotype HLA-C1(+/KIR2DL3(+, even at multivariable analysis, when adjusted for nadir CD4(+ T-cell count, was associated with reduced risk of INR status: odds ratio (95% Confidence Intervals 0.34 (0.13-0.88, P = 0.03. CONCLUSIONS: Reduced presence of the inhibitory KIR2DL3 genotype detected in INR might provoke an imbalance in NK function, possibly leading to increased immune activation, impaired killing of latently infected cells, and higher proviral burden. These factors would hinder full immune recovery during therapy.

    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.

    Toro Giuseppe

    2005-10-01

    Full Text Available Abstract Background HIV-infected patients on long-term highly active antiretroviral therapy often present peculiar patterns of fat redistribution, referred to as lipodystrophy. In spite of recent investigations, it is not known whether and to what extent the main features of lipodystrophy – that is lipoatrophy of peripheral fat at face, limbs and buttocks, as well as fat accumulation at breasts, abdomen and the dorso-cervical region – can be reversible once clinically manifest. Case presentation A 35 year old Caucasian HIV infected female developed severe diffuse lipodystrophy while on highly active antiretroviral therapy. A remarkable increase of breast size, fat accumulation at waist, and a fat pad on her lumbar spine were paralleled by progressive and disfiguring lipoatrophy of face, limbs and buttocks. The patient decided to interrupt her therapy after 20 months, with a stably suppressed viremia and a CD4 lymphocyte count >500/μL. She could carry on a safe treatment interruption for longer than 4 years. Most sites of fat accumulation switched to nearly normal appearance, whereas lipoatrophy was substantially unchanged at all affected sites. Conclusion our observation provides pictorial evidence that lipoatrophy may not be reversible even under ideal circumstances. Therefore, strategies to prevent lipoatrophy should be considered when defining therapeutic regimens for HIV infected patients, especially those at high risk.

Method: This descriptive, cross-sectional study was performed in 2012 at a reference center of the state of São Paulo. Self-report (simplified medication adherence questionnaire [SMAQ] and drug refill parameters were compared to the viral load (clinical parameter of the effectiveness of pharmacotherapy [EP] to evaluate the EP. The “Cuestionario para la Evaluación de la Adhesión al Tratamiento Antiretroviral” (CEAT-VIH was used to evaluate factors related to adherence and the EP and, complementarily, patient self-perception of adherence was compared to the clinical parameter of the EP. Results: Seventy-five patients were interviewed, 60 of whom were considered as adherent from the clinical parameter of the EP and ten were considered as adherent from all parameters. Patient self-perception about adherence was the instrument that best reflected the EP when compared to the standardized self-report questionnaire (SMAQ and drug refill parameter. The level of education and the level of knowledge on HAART were positively correlated to the EP. Forgetfulness, alcohol use, and lack of knowledge about the medications were the factors most frequently reported as a cause of nonadherence. Conclusion: A new parameter of patient self-perception of adherence, which is a noninvasive, inexpensive instrument, could be applied and assessed as easily as self

    Background. Although human immunodeficiency virus (HIV) infection and antiretroviral therapy (ART) affect mitochondrial DNA (mtDNA) content and function, comprehensive evaluations of their effects on mitochondria in muscle, adipose tissue, and blood cells are limited. Methods. Mitochondrial DNA quantification, mitochondrial genome sequencing, and gene expression analysis were performed on muscle, adipose tissue, and peripheral blood mononuclear cell (PBMC) samples from untreated HIV-positive patients, HIV-positive patients receiving nucleoside reverse transcriptase inhibitor (NRTI)–based ART, and HIV-negative controls. Results. The adipose tissue mtDNA/nuclear DNA (nDNA) ratio was increased in untreated HIV-infected patients (ratio, 353) and decreased in those receiving ART (ratio, 162) compared with controls (ratio, 255; P < .05 for both comparisons); the difference between the 2 HIV-infected groups was also significant (P = .002). In HIV-infected participants, mtDNA/nDNA in adipose tissue correlated with the level of activation (CD38+/HLA-DR+) for CD4+ and CD8+ lymphocytes. No significant differences in mtDNA content were noted in muscle or PMBCs among groups. Exploratory DNA microarray analysis identified differential gene expression between patient groups, including a subset of adipose tissue genes. Conclusions. HIV infection and ART have opposing effects on mtDNA content in adipose tissue; immune activation may mediate the effects of HIV, whereas NRTIs likely mediate the effects of ART.

    Monitoring patient adherence to HIV antiretroviral therapy (ART) by patient survey is inherently error prone, justifying a need for objective, biological measures affordable in low-resource settings where HIV/AIDS epidemic is highest. In preliminary studies conducted in Ethiopia and South Africa, we observed loss of cysteine cathepsin activity in peripheral blood mononuclear cells of HIV-positive patients on ART. We optimized a rapid protocol for multiplex cathepsin zymography to quantify cysteine cathepsins, and prospectively enrolled 350 HIV-positive, ART-naïve adults attending the Themba Lethu Clinic, Johannesburg, South Africa, to test if suppressed cathepsin activity could be a biomarker of ART adherence (103 patients were included in final analysis). Poor adherence was defined as detectable viral load (>400 copies/ml) or simplified medication adherence questionnaire, 4-6 months after ART initiation. 86 % of patients with undetectable viral loads after 6 months were cathepsin negative, and cathepsin-positive patients were twice as likely to have detectable viral loads (RR 2.32 95 % CI 1.26-4.29). Together, this demonstrates proof of concept that multiplex cathepsin zymography may be an inexpensive, objective method to monitor patient adherence to ART. Low cost of this electrophoresis-based assay makes it a prime candidate for implementation in resource-limited settings. PMID:26589706

    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

    Full Text Available Objectives: We describe the frequency and types of drug therapy problems (DTPs, and interventions carried out to resolve them, among a cohort of HIV- infected patients on ART in Jos, Nigeria. Methods: A prospective pharmacists’ intervention study was conducted between January and August 2012 at the outpatient HIV clinic of the Jos University Teaching Hospital (JUTH. Pharmacists identified DTPs and made recommendations to resolve them. The main outcome measures were number of DTPs encountered, interventions proposed and acceptance rate of recommendations. Results: A total of 42,416 prescriptions were dispensed to 9339 patients during the eight months study. A total of 420 interventions (Intervention rate of 1 per 100 prescriptions were made to resolve DTPs in 401 (4.3% patients with a mean age of 41 (SD=10 years, and made up of 73% females. DTPs encountered were drug omission (n=89, 21.2%, unnecessary drug (n=55, 13.1% and wrong drug indication (n=55, 13.1%. Recommendations offered included; Addition of another drug to the therapy (n=87, 20.7%, rectification of incomplete prescriptions (n=85, 20.2%, change of drug or dosage (n=67, 16.0%, and discontinuation of the offending drug (n=59, 14.0%. A total of 389 (93% out of 420 of the recommendations were accepted. In all, 50.4% (212 of the problematic prescriptions were changed and dispensed, 22.2% (89 were clarified and dispensed, while wrong identities were corrected in 11.7% (49. However, 7.5% (30 prescriptions were dispensed as prescribed, 5.2% (21 were not dispensed, and 3% (12 were unresolved. Conclusion: Our findings suggest that pharmacists-initiated interventions can ameliorate DTPs in patients receiving ART given the high intervention acceptance rate recorded. The implication of this finding is that pharmacists with requisite training in HIV pharmacotherapy are an excellent resource in detecting and minimizing the effect of antiretroviral drug-related errors.

    Full Text Available This document serves to guide clinicians and programme managers on how to switch from 3 separate antiretroviral (ARV drugs to the new, single, fixed-dose combination (FDC tablet containing tenofovir (TDF, emtricitabine (FTC and efavirenz (EFV. 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

    Full Text Available Introduction: Scientific research has demonstrated the clinical benefits of earlier initiation of antiretroviral treatment (ART, and that ART can markedly reduce HIV transmission to sexual partners. Ensuring universal access to ART for those who need it has long been a core principle of the HIV response, and extending the benefits of ART to key populations is critical to increasing the impact of ART and the overall effectiveness of the HIV response. However, this can only be achieved through coordinated efforts to address political, social, legal and economic barriers that key populations face in accessing HIV services. Discussion: Recent analyses show that HIV prevalence levels among key populations are far higher than among the general population, and they experience a range of biological and behavioural factors, and social, legal and economic barriers that increase their vulnerability to HIV and have resulted in alarmingly low ART coverage. World Health Organization 2014 consolidated guidance on HIV among key populations offers the potential for increased access to ART by key populations, following the same principles as for the general adult population. However, it should not be assumed that key populations will achieve greater access to ART unless stigma, discrimination and punitive laws, policies and practices that limit access to ART and other HIV interventions in many countries are addressed. Conclusions: Rights-based approaches and investments in critical enablers, such as supportive legal and policy environments, are essential to enable wider access to ART and other HIV interventions for key populations. The primary objective of ART should always be to treat the person living with HIV; prevention is an important, additional benefit. ART should be provided only with informed consent. The preventive benefits of treatment must not be used as a pretext for failure to provide other necessary HIV programming for key populations, including

    Full Text Available Background: Tuberculosis (TB is the most common serious opportunistic infection in HIV positive patients and is the manifestation of AIDS in more than 50% of cases in developing countries. TB can occur at any time during the course of HIV infection. Aim: To describe the socio-demographic profile and prevalence of pulmonary tuberculosis (HIV/TB co-infection among HIV positive patients been attended at the antiretroviral therapy clinic (ART clinic at tertiary care teaching hospital of western Maharashtra, India. Materials and Methods: A cross-sectional study was carried out at the ART clinic of Pravara Rural Hospital, Loni, from June 2011 to May 2012. A total of 1012 HIV positive patients, who attended ART clinic, receiving ART treatment during the study period, were included in the analysis. The statistical analysis was performed using SPSS software (Version 17.0. Results: This study showed 1012/172 (17% prevalence of pulmonary tuberculosis among HIV positive patients, of which 87 (50.58% were males and 85 (48.42% were females. Low CD4 count (< 50/μl had statistically significant association with HIV/TB co-infection as compared to HIV infection only ( P < 0.0001. Conclusion: The study showed that 17% of HIV infected persons had tuberculosis co-infection. More strategic preventive measures that enhance body immunity among HIV patients are highly needed as early as possible before they develop active tuberculosis.

  7. Affective disorders in patients with HIV infection: impact of antiretroviral therapy.

    At the beginning of the AIDS pandemic, affective disorders (such as depressed mood) were seen in a considerable number of HIV-1-infected individuals. These disorders were a result of the poor physical condition of the patients, brain involvement by the virus (e.g. encephalopathy) or a reaction to disadvantageous living conditions (losing friends, jobs, etc.). In the era of highly active antiretroviral therapy (HAART), mental illness related to physical weakness is declining, as is the incidence of HIV-1-associated encephalopathy. However, depressed mood and fatigue caused by efavirenz (a standard component of HAART) is becoming increasingly important, particularly in individuals who are infected long-term with HIV-1. Whatever the cause of affective disorders, their presence has been shown to negatively influence adherence to HAART and HIV-1 disease progression. Specialist knowledge of HIV-1 infection, and HAART and its psychiatric complications (particularly in subgroups of patients such as drug abusers and older people), is needed to care adequately for patients. Furthermore, prospective studies are needed to more fully differentiate between the various aetiologies of affective disorders seen in individuals living with HIV/AIDS and to determine their incidence and prevalence. Such information is important to ensure that affective disorders are recognised and adequately treated, which will in turn improve the efficacy of HAART. PMID:16734500

  8. Patients with discordant responses to antiretroviral therapy have impaired killing of HIV-infected T cells.

    Directory of Open Access Journals (Sweden)

    Sekar Natesampillai

    Full Text Available In medicine, understanding the pathophysiologic basis of exceptional circumstances has led to an enhanced understanding of biology. We have studied the circumstance of HIV-infected patients in whom antiretroviral therapy results in immunologic benefit, despite virologic failure. In such patients, two protease mutations, I54V and V82A, occur more frequently. Expressing HIV protease containing these mutations resulted in less cell death, caspase activation, and nuclear fragmentation than wild type (WT HIV protease or HIV protease containing other mutations. The impaired induction of cell death was also associated with impaired cleavage of procaspase 8, a requisite event for HIV protease mediated cell death. Primary CD4 T cells expressing I54V or V82A protease underwent less cell death than with WT or other mutant proteases. Human T cells infected with HIV containing these mutations underwent less cell death and less Casp8p41 production than WT or HIV containing other protease mutations, despite similar degrees of viral replication. The reductions in cell death occurred both within infected cells, as well as in uninfected bystander cells. These data indicate that single point mutations within HIV protease which are selected in vivo can significantly impact the ability of HIV to kill CD4 T cells, while not impacting viral replication. Therefore, HIV protease regulates both HIV replication as well as HIV induced T cell depletion, the hallmark of HIV pathogenesis.

    With prolonged survival and aging of the HIV-infected population in the era of antiretroviral therapy, biopsy series have found a broad spectrum of HIV-related and co-morbid kidney disease in these patients. Our study describes the variety of renal pathology found in a prospective cohort of antiretroviral-experienced patients (the Manhattan HIV Brain Bank) who had consented to postmortem organ donation. Nearly one-third of 89 kidney tissue donors had chronic kidney disease, and evidence of some renal pathology was found in 75. The most common diagnoses were arterionephrosclerosis, HIV-associated nephropathy and glomerulonephritis. Other diagnoses included pyelonephritis, interstitial nephritis, diabetic nephropathy, fungal infection and amyloidosis. Excluding 2 instances of acute tubular necrosis, slightly over one-third of the cases would have been predicted using current diagnostic criteria for chronic kidney disease. Based on semi-quantitative analysis of stored specimens, pre-mortem microalbuminuria testing could have identified an additional 12 cases. Future studies are needed to evaluate the cost-effectiveness of more sensitive methods for defining chronic kidney disease, in order to identify HIV-infected patients with early kidney disease who may benefit from antiretroviral therapy and other interventions known to delay disease progression and prevent complications.

    Objectives To estimate mortality rates and prognostic factors in HIV-positive patients who started combination antiretroviral therapy between 1996–1999 and survived for more than ten years. Methods We used data from 18 European and North American HIV cohort studies contributing to the Antiretroviral Therapy Cohort Collaboration. We followed up patients from ten years after start of combination antiretroviral therapy. We estimated overall and cause-specific mortality rate ratios for age, sex, transmission through injection drug use, AIDS, CD4 count and HIV-1 RNA. Results During 50,593 person years 656/13,011 (5%) patients died. Older age, male sex, injecting drug use transmission, AIDS, and low CD4 count and detectable viral replication ten years after starting combination antiretroviral therapy were associated with higher subsequent mortality. CD4 count at ART start did not predict mortality in models adjusted for patient characteristics ten years after start of antiretroviral therapy. The most frequent causes of death (among 340 classified) were non-AIDS cancer, AIDS, cardiovascular, and liver-related disease. Older age was strongly associated with cardiovascular mortality, injecting drug use transmission with non-AIDS infection and liver-related mortality, and low CD4 and detectable viral replication ten years after starting antiretroviral therapy with AIDS mortality. Five-year mortality risk was <5% in 60% of all patients, and in 30% of those aged over 60 years. Conclusions Viral replication, lower CD4 count, prior AIDS, and transmission via injecting drug use continue to predict higher all-cause and AIDS-related mortality in patients treated with combination antiretroviral therapy for over a decade. Deaths from AIDS and non-AIDS infection are less frequent than deaths from other non-AIDS causes. PMID:27525413

    Full Text Available Background: Antiretroviral therapy has transformed the HIV infection into a chronic manageably disease. Optimal adherence (≥ 95% has required to achieve treatment success; however, still non-adherence remains major problem among patients receiving antiretroviral therapy (ART. The aim of this study was to determine adherences rate and evaluate factors affecting adherence among patients on ART in Dessie Referral Hospital (DRH. Materials and Methods: A cross sectional study employing both qualitative and quantitative methods was used. A total of 130 people living with HIV/AIDS on ART were included. All patients who came to the hospital during study period were considered based on convenient sampling technique. Chi-Square test is used to examine the association of adherence with associated factors. Both data entry and analysis was done using SPSS version 16. Results: Of 130 respondents, 58(44.6% were males and 72(55.4% were females and 107 (82.3% had 100% adherences, 10(7.7% had 95 -100% and the rest, 13(10% had <95% adherences with overall adherence rate of 90% for last month prior to the study period. The main reasons for non-adherence were 12(37.5% forgetfulness, 7(21.8% being away from home and 4 (12.5% being extremely ill. Use of other medications in addition to antiretroviral drugs (p=0.01, treatment fit into daily routines (p=0.01, family disclosure (p=0.01, active substance use (p=0.04 and living condition (p=0.00 were significantly associated with adherence to ART. Conclusion: The self reported adherence rate to ART (90% was found to be relatively higher which needs inclusion of other methods to ensure consistency of this value. Forgetfulness, being away from home and being extremely ill were the foremost reasons for non-adherence. The patients should be encouraged to maintain this high level of adherence.

    Full Text Available Purpose of the study Previous investigation into antiretroviral (ARV therapy switches in our HIV cohort suggested an annual switch rate of 20% in 2006 with 60% of switches being secondary to toxicity [1]. The purpose of this study was to investigate whether this switch rate has changed in recent years, determine reasons why patients change regimens, and identify which ARVs are most likely to be switched for toxicity concerns. Methods The electronic patient database was reviewed to identify all patients within our HIV cohort who switched ARV therapy between 1st December 2009 and 31st May 2011. Details of which ARVs were switched and the reasons why were recorded. Any switches due to toxicity were investigated further to identify the actual or perceived adverse effect. Summary of results Nine hundred and twenty-three regimens were switched over 18 months affecting 12% (n = 722 of patients on treatment during this time. The most common reason for switching medication was due to toxicity, occurring in 452 (49% cases. Other reasons included simplification (15%, clinical trials (8%, virological failure (8% and drug interactions (4%. The remaining 16% switched for various reasons including pregnancy and co-morbidities. Of 452 switches for toxicity (or perceived toxicity, 122 (27% were due to CNS side effects (89 out of a total of 122 were related to efavirenz, 64 (14% gastrointestinal disturbances (38/64 related to protease inhibitors, 54 (12% actual/perceived cardiovascular risk (21/54 related to abacavir and 21/54 related to saquinavir, 54 (12% hepatotoxicity (21/54 related to atazanavir and 14/54 related to efavirenz, 42 (9% metabolic concerns (24/42 related to protease inhibitors and 38 (8% renal toxicity (28/38 related to tenofovir. Other toxicities accounted for 78 (18% switches. An observed toxicity switch rate (OTSR per 1000 patient years (95% CI was calculated for each ARV.

    Full Text Available Antiretroviral therapy (ART has reduced morbidity and mortality related to human immunodeficiency virus (HIV infection, but in spite of this advance, HIV mutations decrease antiretroviral susceptibility, thus contributing to treatment failure in patients. Genotyping HIV-1 allows the selection of new drugs after initial drug failure. This study evaluated the genotypic profile of HIV-1 isolates from treated (drug-experienced patients in Paraná, Brazil. The prevalence of mutations in reverse transcriptase (RT and protease (PR genes were assessed. We analyzed 467 genotypes of patients with HIV-1 viral loads above 1,000 copies/mL. Mutations at HIV-1 RT and PR genes and previously used ART regimens were recorded.

    Background. Human immunodeficiency virus (HIV)–infected people who inject drugs (PWID) frequently encounter barriers accessing and remaining on antiretroviral therapy (ART). Some studies have suggested that opioid substitution therapy (OST) could facilitate PWID's engagement with HIV services. We conducted a systematic review and meta-analysis to evaluate the impact of concurrent OST use on ART-related outcomes among HIV-infected PWID. Methods. We searched Medline, PsycInfo, Embase, Global Health, Cochrane, Web of Science, and Social Policy and Practice databases for studies between 1996 to November 2014 documenting the impact of OST, compared to no OST, on ART outcomes. Outcomes considered were coverage and recruitment onto ART, adherence, viral suppression, attrition from ART, and mortality. Meta-analyses were conducted using random-effects modeling, and heterogeneity assessed using Cochran Q test and I2 statistic. Results. We identified 4685 articles, and 32 studies conducted in North America, Europe, Indonesia, and China were included. OST was associated with a 69% increase in recruitment onto ART (hazard ratio [HR], 1.69; 95% confidence interval [CI], 1.32–2.15), a 54% increase in ART coverage (odds ratio [OR], 1.54; 95% CI, 1.17–2.03), a 2-fold increase in adherence (OR, 2.14; 95% CI, 1.41–3.26), and a 23% decrease in the odds of attrition (OR, 0.77; 95% CI, .63–.95). OST was associated with a 45% increase in odds of viral suppression (OR, 1.45; 95% CI, 1.21–1.73), but there was limited evidence from 6 studies for OST decreasing mortality for PWID on ART (HR, 0.91; 95% CI, .65–1.25). Conclusions. These findings support the use of OST, and its integration with HIV services, to improve the HIV treatment and care continuum among HIV-infected PWID. PMID:27343545

Despite obvious advances over the past 3 decades, new approaches toward improved management of infected individuals are still required. Drug distribution to the central nervous system (CNS is required in order to limit and control viral infection, but the presence of natural barrier structures, in particular the blood–brain barrier, strongly limits the perfusion of anti-HIV compounds into this anatomical site. Nanotechnology-based approaches may help providing solutions for antiretroviral drug delivery to the CNS by potentially prolonging systemic drug circulation, increasing the crossing and reducing the efflux of active compounds at the blood–brain barrier, and providing cell/tissue-targeting and intracellular drug delivery. After an initial overview on the basic features of HIV infection of the CNS and barriers to active compound delivery to this anatomical site, this review focuses on recent strategies based on antiretroviral drug-loaded solid nanoparticles and drug nanosuspensions for the potential management of HIV infection of the CNS.

    Adherence continues to be a major barrier to successful treatment with highly active antiretroviral therapy (HAART) for HIV-infected individuals. HIV-infected adolescents and young adults face a lifetime of treatment with HAART. Often, individuals who struggle with adherence to HAART face multiple barriers that would therefore impact on the success of any single modality intervention. Thus, we conducted a cross-sectional, observational study to determine the prevalence of personal barriers to...

    2016-06-01

    Chronic kidney disease (CKD) has emerged as an important health concern in HIV-positive individuals. Preventing long-term kidney toxicity from an antiretroviral therapy is therefore critical. Selected antiretroviral agents, especially tenofovir disoproxil fumarate (TDF) and some ritonavir-boosted protease inhibitors (PI/rs), have been associated with increased risk of CKD. However, the CKD risk attributable to these agents is overall small, especially in those with low baseline risk of CKD and normal renal function. CKD risk in HIV-positive individuals can be further minimized by timely identification of those with worsening renal function and discontinuation of potentially nephrotoxic agents. Clinicians can use several monitoring tools, including the D:A:D risk score and routine measurements of estimated glomerular filtration (eGFR) and proteinuria, to identify high-risk individuals who may require an intervention. Tenofovir alafenamide (TAF), a TDF alternative, promises to be safer in terms of TDF-associated kidney and bone toxicity. While the short-term data on TAF does indicate lower eGFR decline and lower risk of proteinuria (vs. TDF), long-term data on renal safety of TAF are still awaited. Promising results have also emerged from recent trials on alternative dual-therapy antiretroviral regimens which exclude the nucleoside(tide) reverse transcriptase class as well as possibly the PI/rs, thereby reducing the drug burden, and possibly the toxicity. However, long-term safety or benefits of these dual-therapy regimens are still unclear and will need to be studied in future prospective studies. Finally, addressing risk factors such as hypertension and diabetes will continue to be important in this population. PMID:27130284

    Objective To investigate the impact of one-year highly active antiretroviral therapy ( HAART) on antiviral effect and immune reconstruction in HIV/AIDS patients. Methods Thirty-five HIV/AIDS patients were initially treated with HAART when CD4 + T cells were <350/μL, blood samples were taken at the HAART time point 0,6,12 months, the virus load was tested by RT-PCR, CD4 + T cells, CDS + T cells, CD4 + naive cells, CD4 + memory cells and CDS + activated cells were detected by flow-cytometry. Results The average virus load of 35 patients was (4. 62 ± 1. 09) × 106 copies/mL before HAART, and was lower than the lower limit of detection value after HAART for 6 months and 12 months. The levels of CD4 + T cells, CD4 + naive cells and CD4 + memory cells were (312 ± 109. 22) /μL, (150 ± 57. 34)/μL and (212 ± 48. 06)/μL respectively after HAART for 12 months, while they were (183 ± 83. 73)/μL, (73 ± 20. 40)/μL and (119 ± 30. 42)/μL respectively at the baseline (P<0. 01), but they were still lower than healthy control group([768 ± 146. 41]/μL, [424 ± 87. 06]/μL and [442 ± 61. 40]/μL, respectively)(P<0. 05) ;the level of CDS + T cells were(427 ± 99. 79)/μL after HAART, which decreased significantly compared with (597 ±111. 43)/μL of the baseline (P<0. 05), but still higher than (208 ± 37. 39)/μL of healthy control group (P<0. 05). Conclusion HAART can both inhibit virus replication rapidly and reconstruct HIV/AIDS patients' immunity partially.%目的 研究高效抗反转录病毒治疗(HAART)1年,对HIV/AIDS患者免疫重建效果的影响.方法 确认人免疫缺陷病毒(HIV)感染者35例,检测CD4+T淋巴细胞<350/μL,开始HAART治疗,并于治疗0、6、12个月时分别检测其病毒载量及CD4+T淋巴细胞、CD8+T淋巴细胞、CD4+童贞细胞、CD4+记忆细胞、CD8+激活细胞计数.结果 治疗前,HIV RNA处于高复制水平,平均(4.62±1.09)×106copies/mL,HAART治疗6个月及12个月时均低于检测下限.患者的CD4+T

    The results from the HPTN 052 trial have increased the focus on use of antiretroviral therapy (ART) for prevention of HIV transmission; however, condom use also effectively prevents HIV transmission. Studies in heterosexual serodiscordant couples with viral suppression have so far only reported...... follow-up data for 330 couple-years when condoms were not being used. Data are even more limited for anal sex in men who have sex with men. Additional data on the effectiveness of ART as prevention when practicing condom-less sex is urgently needed....

    Coadministration of nevirapine-based antiretroviral therapy (ART) and artemether-lumefantrine is reported to result in variable changes in lumefantrine exposure. We conducted an intensive pharmacokinetic study with 11 HIV-infected adults who were receiving artemether-lumefantrine plus nevirapine-based ART, and we compared the results with those for 16 HIV-negative adult historical controls. Exposure to artemether and lumefantrine was significantly lower and dihydroartemisinin exposure was unchanged in subjects receiving nevirapine-based ART, compared with controls. Nevirapine exposure was unchanged before and after artemether-lumefantrine administration. PMID:26392500

    Toxoplasmosis is a severe opportunistic infection in patients infected with the human immunodeficiency virus (HIV). The lung is a major site of infection after the central nervous system. In this report we described two cases of pneumonia due to Toxoplasma gondii infection in HIV patients with antiretroviral therapy. Clinical and radiological abnormalities are not specific. Pulmonary toxoplasmosis should be considered in HIV-infected patients with late stage of HIV, CD4 count less than 100 cells/µl and a poor adherence to HAART.

    Full Text Available PURPOSE: This study assessed the incidence and types of medication errors, interventions and outcomes in patients on antiretroviral therapy (ART in selected HIV treatment centres in Nigeria. METHODS: Of 69 health facilities that had program for active screening of medication errors, 14 were randomly selected for prospective cohort assessment. All patients who filled/refilled their antiretroviral medications between February 2009 and March 2011 were screened for medication errors using study-specific pharmaceutical care daily worksheet (PCDW. All potential or actual medication errors identified, interventions provided and the outcomes were documented in the PCDW. Interventions included pharmaceutical care in HIV training for pharmacists amongst others. Chi-square was used for inferential statistics and P0.05. The major medications errors identified were 26.4% incorrect ART regimens prescribed; 19.8% potential drug-drug interaction or contraindication present; and 16.6% duration and/or frequency of medication inappropriate. Interventions provided included 67.1% cases of prescriber contacted to clarify/resolve errors and 14.7% cases of patient counselling and education; 97.4% of potential/actual medication error(s were resolved. CONCLUSION: The incidence rate of medication errors was somewhat high; and majority of identified errors were related to prescription of incorrect ART regimens and potential drug-drug interactions; the prescriber was contacted and the errors were resolved in majority of cases. Active screening for medication errors is feasible in resource-limited settings following a capacity building intervention.

    Full Text Available Liver related complications are currently the leading cause of morbidity and mortality among human immunodeficiency virus (HIV infected individuals. In HIV monoinfected individuals on therapy, liver injury has been associated with the use of antiretroviral agents as most of them exhibit some degree of toxicity. In this study we proposed a mathematical model with the aim of investigating hepatotoxicity of combinational therapy of antiretroviral drugs. Therapy efficacy and toxicity were incorporated in the model as dose-response functions. With the parameter values used in the study, protease inhibitors-based regimens were found to be more toxic than nonnucleoside reverse transcriptase inhibitors-based regimens. In both regimens, the combination of stavudine and zidovudine was the most toxic baseline nucleoside reverse transcriptase inhibitors followed by didanosine with stavudine. However, the least toxic combinations were zidovudine and lamivudine followed by didanosine and lamivudine. The study proposed that, under the same second line regimens, the most toxic first line combination gives the highest viral load and vice versa.

    Full Text Available A case-cohort study, within a multi-country trial of antiretroviral therapy (ART efficacy (Prospective Evaluation of Antiretrovirals in Resource Limited Settings (PEARLS, was conducted to determine if pre-ART serum selenium deficiency is independently associated with human immunodeficiency virus (HIV disease progression after ART initiation. Cases were HIV-1 infected adults with either clinical failure (incident World Health Organization (WHO stage 3, 4 or death by 96 weeks or virologic failure by 24 months. Risk factors for serum selenium deficiency (<85 μg/L pre-ART and its association with outcomes were examined. Median serum selenium concentration was 82.04 μg/L (Interquartile range (IQR: 57.28–99.89 and serum selenium deficiency was 53%, varying widely by country from 0% to 100%. In multivariable models, risk factors for serum selenium deficiency were country, previous tuberculosis, anemia, and elevated C-reactive protein. Serum selenium deficiency was not associated with either clinical failure or virologic failure in multivariable models. However, relative to people in the third quartile (74.86–95.10 μg/L of serum selenium, we observed increased hazards (adjusted hazards ratio (HR: 3.50; 95% confidence intervals (CI: 1.30–9.42 of clinical failure but not virologic failure for people in the highest quartile. If future studies confirm this relationship of high serum selenium with increased clinical failure, a cautious approach to selenium supplementation might be needed, especially in HIV-infected populations with sufficient or unknown levels of selenium.

    Full Text Available Objective: To learn the experiences of pregnant women with HIV/AIDS in relation to adherence to antiretroviral therapy in two public hospitals of reference for HIV/AIDS in Fortaleza-CE, Brazil. Methods: A descriptive study conducted with 24 pregnant women who were in prenatal care and use of antiretroviral therapy. Sociodemographic and obstetric data and information regarding the experience with antiretroviral therapy adherence were collected from July to September 2009, through a semi-structured interview. Results: Womenhad a mean age of 29, low income, low education and a stable partner. It was found that some factors affect pregnant women adherence to antiretroviral therapy. Among these, stand out not accepting the diagnosis and the absence of signs and symptoms of AIDS. However,the fear of transmitting the virus to the baby acted as a stimulus for pregnant women adhere to treatment. Conclusion: The non-acceptance of diagnosis and the absence of signs and symptoms of AIDS negatively affect pregnant women adherence to antiretroviral treatment. On the other hand, the fear that the child be born with the virus and the desire to continue to live are stimuli to adherence.

    Five patients (P) were followed-up for an average of 7.73years after highly active antiretroviral therapy (HAART) initiation. Patients' immune and virological status were determined by periodical CD4+T-cell counts and HIV and HCV viral load. HCV populations were studied using longitudinal high throughput sequence data obtained in parallel by virological and immunological parameters. Two patients (P7, P28) with sub-optimal responses to HAART presented HCV viral loads significantly higher than those recorded for two patients (P1, P18) that achieved good responses to HAART. Interestingly, HCV populations from P7 and P28 displayed a stable phylogenetic structure, whereas HCV populations from P1 and P18showeda significant increase in their phylogenetic structure, followed by a decrease after achieving acceptable CD4+T-cell counts (>500 cell/μl). The fifth patient (P25) presented high HCV viral loads, preserved CD4+T-cell counts from baseline and all along the follow-up, and displayed a constant viral phylogenetic structure. These results strongly suggest that HAART-induced immune recovery induces a decrease in HCV viral load and an increase in the HCV population phylogenetic structure likely reflecting the virus diversification in response to the afresh immune response. The relatively low HCV viral load observed in the HAART responder patients suggests that once HCV is adapted it reaches a maximum number of haplotypes higher than that achieved during the initial stages of the immune response as inferred from the two recovering patients. Future studies using larger number of patients are needed to corroborate these hypotheses. PMID:27234841

    Full Text Available OBJECTIVE: To estimate the prevalence of drug-resistant tuberculosis (TB and describe the resistance patterns in patients commencing antiretroviral therapy (ART in an HIV clinic in Durban, South Africa. DESIGN: Cross-sectional cohort study. METHODS: Consecutive HIV-infected adults (≥ 18y/o initiating HIV care were enrolled from May 2007-May 2008, regardless of signs or symptoms of active TB. Prior TB history and current TB treatment status were self-reported. Subjects expectorated sputum for culture (MGIT liquid and 7H11 solid medium. Positive cultures were tested for susceptibility to first- and second-line anti-tuberculous drugs. The prevalence of drug-resistant TB, stratified by prior TB history and current TB treatment status, was assessed. RESULTS: 1,035 subjects had complete culture results. Median CD4 count was 92/µl (IQR 42-150/µl. 267 subjects (26% reported a prior history of TB and 210 (20% were receiving TB treatment at enrollment; 191 (18% subjects had positive sputum cultures, among whom the estimated prevalence of resistance to any antituberculous drug was 7.4% (95% CI 4.0-12.4. Among those with prior TB, the prevalence of resistance was 15.4% (95% CI 5.9-30.5 compared to 5.2% (95% CI 2.1-8.9 among those with no prior TB. 5.1% (95% CI 2.4-9.5 had rifampin or rifampin plus INH resistance. CONCLUSIONS: The prevalence of TB resistance to at least one drug was 7.4% among adults with positive TB cultures initiating ART in Durban, South Africa, with 5.1% having rifampin or rifampin plus INH resistance. Improved tools for diagnosing TB and drug resistance are urgently needed in areas of high HIV/TB prevalence.

    Objectives To evaluate which indirect method for assessing adherence best reflects highly active antiretroviral therapy (HAART) effectiveness and the factors related to adherence. Method This descriptive, cross-sectional study was performed in 2012 at a reference center of the state of São Paulo. Self-report (simplified medication adherence questionnaire [SMAQ]) and drug refill parameters were compared to the viral load (clinical parameter of the effectiveness of pharmacotherapy [EP]) to evaluate the EP. The “Cuestionario para la Evaluación de la Adhesión al Tratamiento Antiretroviral” (CEAT-VIH) was used to evaluate factors related to adherence and the EP and, complementarily, patient self-perception of adherence was compared to the clinical parameter of the EP. Results Seventy-five patients were interviewed, 60 of whom were considered as adherent from the clinical parameter of the EP and ten were considered as adherent from all parameters. Patient self-perception about adherence was the instrument that best reflected the EP when compared to the standardized self-report questionnaire (SMAQ) and drug refill parameter. The level of education and the level of knowledge on HAART were positively correlated to the EP. Forgetfulness, alcohol use, and lack of knowledge about the medications were the factors most frequently reported as a cause of nonadherence. Conclusion A new parameter of patient self-perception of adherence, which is a noninvasive, inexpensive instrument, could be applied and assessed as easily as self-report (SMAQ) during monthly drug refill, since it allows monitoring adherence through pharmaceutical assistance. Therefore, patient adherence to HAART could be evaluated using self-perception (CEAT-VIH) and the viral load test. PMID:27695297

    Full Text Available This study aimed to describe the epidemiology and risk factors of cholelithiasis and nephrolithiasis among HIV-positive patients in the era of combination antiretroviral therapy.We retrospectively reviewed the medical records of HIV-positive patients who underwent routine abdominal sonography for chronic viral hepatitis, fatty liver, or elevated aminotransferases between January 2004 and January 2015. Therapeutic drug monitoring of plasma concentrations of atazanavir was performed and genetic polymorphisms, including UDP-glucuronosyltransferase (UGT 1A1*28 and multidrug resistance gene 1 (MDR1 G2677T/A, were determined in a subgroup of patients who received ritonavir-boosted or unboosted atazanavir-containing combination antiretroviral therapy. Information on demographics, clinical characteristics, and laboratory testing were collected and analyzed.During the 11-year study period, 910 patients who underwent routine abdominal sonography were included for analysis. The patients were mostly male (96.9% with a mean age of 42.2 years and mean body-mass index of 22.9 kg/m2 and 85.8% being on antiretroviral therapy. The anchor antiretroviral agents included non-nucleoside reverse-transcriptase inhibitors (49.3%, unboosted atazanavir (34.4%, ritonavir-boosted lopinavir (20.4%, and ritonavir-boosted atazanavir (5.5%. The overall prevalence of cholelithiasis and nephrolithiasis was 12.5% and 8.2%, respectively. Among 680 antiretroviral-experienced patients with both baseline and follow-up sonography, the crude incidence of cholelithiasis and nephrolithiasis was 4.3% and 3.7%, respectively. In multivariate analysis, the independent factors associated with incident cholelithiasis were exposure to ritonavir-boosted atazanavir for >2 years (adjusted odds ratio [AOR], 6.29; 95% confidence interval [CI], 1.12-35.16 and older age (AOR, 1.04; 95% CI, 1.00-1.09.

    Full Text Available Throughout Asia, people who use drugs are confined in facilities referred to as compulsory drug detention and rehabilitation centers. The limited transparency and accessibility of these centers has posed a significant challenge to evaluating detainees and detention conditions directly. Despite HIV being highly prevalent in this type of confined setting, direct evaluation of detainees with HIV and their access to medical care has yet to be reported in the literature.We evaluated the health status of 100 adult male detainees with HIV and their access to medical care in the two largest Malaysian compulsory drug detention and rehabilitation centers holding HIV-infected individuals.Approximately 80% of all detainees with HIV were surveyed in each detention center. Most participants reported multiple untreated medical conditions. None reported being able to access antiretroviral therapy during detention and only 9% reported receiving any HIV-related clinical assessment or care. Nearly a quarter screened positive for symptoms indicative of active tuberculosis, yet none reported having been evaluated for tuberculosis. Although 95% of participants met criteria for opioid dependence prior to detention, none reported being able to access opioid substitution therapy during detention, with 86% reporting current cravings for opioids and 87% anticipating relapsing to drug use after release. Fourteen percent of participants reported suicidal ideation over the previous two weeks.We identified a lack of access to antiretroviral therapy in two of the six compulsory drug detention and rehabilitation centers in Malaysia designated to hold HIV-infected individuals and found significant, unmet health needs among detainees with HIV. Individuals confined under such conditions are placed at considerably high risk for morbidity and mortality. Our findings underscore the urgent need for evidence-based drug policies that respect the rights of people who use drugs and seek

    The perception in low-resource settings that investment of resources in people living with HIV (PLHIV) is wasted because AIDS is both an incurable and deadly disease is known as resource-based stigma. In this paper, we draw on in-depth interviews (IDI), focus group discussions (FGD), and key informant interviews (KII) with 77 HIV-positive microfinance participants and nongovernmental organization leaders to examine resource-based stigma in the context of increased access to antiretroviral therapy (ART) at an individual, household, and community level in Côte d'Ivoire. The purpose of this exploratory paper is to examine: (1) resource-based stigmatization in the era of ART and (2) the relationship among microfinance, a poverty-reduction intervention, and HIV stigmatization. The frequency with which resource-based stigma was discussed by respondents suggests that it is an important component of HIV-related stigma in this setting. It affected PLHIV's access to material as well as social resources, leading to economic discrimination and social devaluation. Participation in village savings and loans groups, however, mitigated resource-based HIV stigma, suggesting that in the era of increased access to antiretroviral therapy, economic programs should be considered as one possible HIV stigma-reduction intervention.

    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

    2016-06-01

    Since the advent of combination antiretroviral therapy to successfully treat HIV infection, drug-drug interactions (DDIs) have become a significant problem as many antiretrovirals (ARVs) are metabolized in the liver. Antituberculous therapy traditionally includes rifamycins, particularly rifampicin. Rifabutin (RBT) has shown similar efficacy as rifampicin but induces CYP3A4 to a lesser degree and is less likely to have DDIs with ARVs. We identified 14 DDI pharmacokinetic studies on HIV monoinfected and HIV-tuberculosis coinfected individuals, and the remaining studies were healthy volunteer studies. Although RBT may be coadministered with most nonnucleoside reverse transcriptase inhibitors, identifying the optimal dose with ritonavir-boosted or cobicistat-boosted protease inhibitors is challenging because of concern about adverse effects with increased RBT exposure. Limited healthy volunteer studies on other ARV drug classes and RBT suggest that dose modification may be unnecessary. The paucity of data assessing clinical tuberculosis endpoints concurrently with RBT and ARV pharmacokinetics limits evidence-based recommendations on the optimal dose of RBT within available ARV drug classes.

    Background: The failure to increase CD4+ T-cell counts in some antiretroviral therapy suppressed participants (immunodiscordance) has been related to perturbed CD4+ T-cell homeostasis and impacts clinical evolution. Methods: We evaluated different definitions of immunodiscordance based on CD4+ T-cell counts (cutoff) or CD4+ T-cell increases from nadir value (ΔCD4) using supervised random forest classification of 74 immunological and clinical variables from 196 antiretroviral therapy suppressed individuals. Unsupervised clustering was performed using relevant variables identified in the supervised approach from 191 individuals. Results: Cutoff definition of CD4+ cell count 400 cells/μl performed better than any other definition in segregating immunoconcordant and immunodiscordant individuals (85% accuracy), using markers of activation, nadir and death of CD4+ T cells. Unsupervised clustering of relevant variables using this definition revealed large heterogeneity between immunodiscordant individuals and segregated participants into three distinct subgroups with distinct production, programmed cell-death protein-1 (PD-1) expression, activation and death of T cells. Surprisingly, a nonnegligible number of immunodiscordant participants (22%) showed high frequency of recent thymic emigrants and low CD4+ T-cell activation and death, very similar to immunoconcordant participants. Notably, human leukocyte antigen - antigen D related (HLA-DR) PD-1 and CD45RA expression in CD4+ T cells allowed reproducing subgroup segregation (81.4% accuracy). Despite sharp immunological differences, similar and persistently low CD4+ values were maintained in these participants over time. Conclusion: A cutoff value of CD4+ T-cell count 400 cells/μl classified better immunodiscordant and immunoconcordant individuals than any ΔCD4 classification. Immunodiscordance may present several, even opposite, immunological patterns that are identified by a simple immunological follow-up. Subgroup

    Full Text Available Abstract Background After rapid scaling up of antiretroviral therapy in HIV-1-infected patients, the data of primary HIV-1 drug resistance in Thailand is still limited. This study aims to determine the prevalence and associated factors of primary HIV-1 drug resistance in Thailand. Methods A prospective observational study was conducted among antiretroviral-naïve HIV-1-infected Thai patients from 2007 to 2010. HIV-1 subtypes and mutations were assayed by sequencing a region of HIV-1 pol gene. Surveillance drug resistance mutations recommended by the World Health Organization for surveillance of transmitted HIV-1 drug resistance in 2009 were used in all analyses. Primary HIV-1 drug resistance was defined as the presence of one or more surveillance drug resistance mutations. Results Of 466 patients with a mean age of 38.8 years, 58.6% were males. Risks of HIV-1 infection included heterosexual (77.7%, homosexual (16.7%, and intravenous drug use (5.6%. Median (IQR CD4 cell count and HIV-1 RNA were 176 (42-317 cells/mm3 and 68,600 (19,515-220,330 copies/mL, respectively. HIV-1 subtypes were CRF01_AE (86.9%, B (8.6 and other recombinants (4.5%. The prevalence of primary HIV-1 drug resistance was 4.9%; most of these (73.9% had surveillance drug resistance mutations to only one class of antiretroviral drugs. The prevalence of patients with NRTI, NNRTI, and PI surveillance drug resistance mutations was 1.9%, 2.8% and 1.7%, respectively. From logistic regression analysis, there was no factor significantly associated with primary HIV-1 drug resistance. There was a trend toward higher prevalence in females [odds ratio 2.18; 95% confidence interval 0.896-5.304; p = 0.086]. Conclusions There is a significant emergence of primary HIV-1 drug resistance in Thailand after rapid scaling up of antiretroviral therapy. Although HIV-1 genotyping prior to antiretroviral therapy initiation is not routinely recommended in Thailand, our results raise concerns about the

    Full Text Available Abstract Background Data on lipid profile derangements induced by antiretroviral treatment in Africa are scarce. The aim of this study was to determine the prevalence and characteristics of lipid profile derangements associated with first-line highly active antiretroviral therapy (ART among Cameroonians living with human immunodeficiency virus (HIV infection. Methods This cross-sectional study was conducted between November 2009 and January 2010, and involved 138 HIV patients who had never received ART (ART-naive group and 138 others treated for at least 12 months with first line triple ART regimens that included nevirapine or efavirenz (ART group. Lipid profile was determined after overnight fast and dyslipidemia diagnosed according to the US National Cholesterol Education Program III criteria. Data comparison used chi-square test, Student t-test and logistic regressions. Results The prevalence of total cholesterol ≥ 200 mg/dl was 37.6% and 24.6% respectively in ART group and ART-naive groups (p = 0.019. The equivalents for LDL-cholesterol ≥ 130 mg/dl were 46.4% and 21% (p ≤ 0.001. Proportions of patients with total cholesterol/HDL-cholesterol ratio ≥ 5 was 35.5% in ART group and 18.6% in ART-naive group (p ≤ 0.001. The distribution of HDL-cholesterol and triglycerides was similar between the two groups. In multivariable analysis adjusted for age, sex, body mass index, CD4 count and co-infection with tuberculosis, being on ART was significantly and positively associated with raised total cholesterol, LDL-cholesterol and TC/HDL cholesterol. The adjusted odd ratios (95% confidence interval, p-value ART-treated vs. ART-naïve was 1.82 (1.06-1.12, p = 0.02 for TC ≥ 200 mg/dl; 2.99 (1.74-5.15, p Conclusions First-line antiretroviral therapy that includes nonnucleoside reverse transcriptase inhibitors is associated with pro-atherogenic adverse lipid profile in people with HIV-1 infection compared to untreated HIV-infected subjects in

    Full Text Available Background: HIV-TB (tuberculosis coinfection has emerged as a major public health threat. Given the multifactorial enabling environment in a resource-constrained setting like India, the consequences are of epidemic proportions. Aims: This study was aimed at identifying the clinical and epidemiological determinants underlying HIV-TB coinfection. Settings and Design: A retrospective review of patient records was done from the antiretroviral therapy center (ART center at a district hospital in southern India between May and August 2012. Materials and Methods: Secondary data of 684 patients on ART as well as pre-ART were collected between July 2008 and June 2012 and were analyzed. Statistical Analysis: Descriptive analysis, χ2 , and Wilcoxon signed rank tests were used with SPSS version 15.0 to draw significant statistical inferences. Results: HIV-TB coinfection was diagnosed in 18.9% with higher prevalence among males (75.3%, in the sexually active age group 31-45 years (61.3%, with less than primary education (44.15%, who were married (56.1%, laborers (42.4%, from rural backgrounds (88.2%, and having low income-earning capacity (94.4%. Transmission was predominantly through the heterosexual route. The key entry point was the integrated counseling and testing center (ICTC (47.4%. Pulmonary tuberculosis (58.8% was predominantly found followed by extrapulmonary tuberculosis (38.2% and both in 3.1%. A favorable outcome was observed in 69.3% of coinfected patients with 89.2% on ART and 97.2% currently on DOTS therapy. The Wilcoxon signed-rank test found significant association between rises in CD4 counts after the 6 th -month follow up (P < 0.05. Coinfected patients had a case fatality rate of 25%. Conclusions: The prevalence of HIV-TB coinfection recorded in this sample was 18.86%. ICTC implemented by NACO emerged as an effective entry point, while Revised National Tuberculosis Control Program referred 1.6% (n = 11 of the patients to the ART center

  18. Antiretroviral therapy optimisation without genotype resistance testing: a perspective on treatment history based models.

    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.

    Full Text Available Michael L Scanlon,1,2 Rachel C Vreeman1,21Department of Pediatrics, Indiana University School of Medicine, Indianapolis, IN, USA; 2USAID, Academic Model Providing Access to Healthcare (AMPATH Partnership, Eldoret, KenyaAbstract: The rollout of antiretroviral therapy (ART significantly reduced human immunodeficiency virus (HIV-related morbidity and mortality, but good clinical outcomes depend on access and adherence to treatment. In resource-limited settings, where over 90% of the world’s HIV-infected population resides, data on barriers to treatment are emerging that contribute to low rates of uptake in HIV testing, linkage to and retention in HIV care systems, and suboptimal adherence rates to therapy. A review of the literature reveals limited evidence to inform strategies to improve access and adherence with the majority of studies from sub-Saharan Africa. Data from observational studies and randomized controlled trials support home-based, mobile and antenatal care HIV testing, task-shifting from doctor-based to nurse-based and lower level provider care, and adherence support through education, counseling and mobile phone messaging services. Strategies with more limited evidence include targeted HIV testing for couples and family members of ART patients, decentralization of HIV care, including through home- and community-based ART programs, and adherence promotion through peer health workers, treatment supporters, and directly observed therapy. There is little evidence for improving access and adherence among vulnerable groups such as women, children and adolescents, and other high-risk populations and for addressing major barriers. Overall, studies are few in number and suffer from methodological issues. Recommendations for further research include health information technology, social-level factors like HIV stigma, and new research directions in cost-effectiveness, operations, and implementation.

    Full Text Available Objectives:Despite the advent of antiretroviral therapy (ART, many children, particularly in the rural communities of Zimbabwe, remain vulnerable. The purpose of this study was to determine the factors and challenges facing children on antiretroviral therapy (ART in Brunapeg area of Mangwe District, Zimbabwe.Methods:A mixed-method approach involving interviewer-guided focus group discussions and piloted semi-structured questionnaires was utilized to collect data from different key population groups. The data obtained were analyzed through content coding procedures based on a set of predetermined themes of interest.Results:A number of challenges emerged as barriers to the success of antiretroviral therapy for children. Primary care givers were less informed about HIV and AIDS issues for people having direct impact on the success of antiretroviral therapy in children whilst some were found to be taking the antiretroviral drugs meant for the children. It also emerged that some primary care givers were either too young or too old to care for the children while others had failed to disclose to the children why they frequently visited the Opportunistic Infections (OI clinic. Most primary care givers were not the biological parents of the affected children. Other challenges included inadequate access to health services, inadequate food and nutrition and lack of access to clean water, good hygiene and sanitation. The lack of community support and stigma and discrimination affected their school attendance and hospital visits. All these factors contributed to non-adherence to antiretroviral drugs.Conclusions and Public Health Implications:Children on ART in rural communities in Zimbabwe remain severely compromised and have unique problems that need multi-intervention strategies both at policy and programmatic levels. Effective mitigating measures must be fully established and implemented in rural communities of developing countries in the fight for

    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).

    Full Text Available Abstract Human Immunodeficiency Virus Type 1 (HIV-1 protease inhibitors (PIs are the most potent class of drugs in antiretroviral therapies. However, viral drug resistance to PIs could emerge rapidly thus reducing the effectiveness of those drugs. Of note, all current FDA-approved PIs are competitive inhibitors, i.e., inhibitors that compete with substrates for the active enzymatic site. This common inhibitory approach increases the likelihood of developing drug resistant HIV-1 strains that are resistant to many or all current PIs. Hence, new PIs that move away from the current target of the active enzymatic site are needed. Specifically, allosteric inhibitors, inhibitors that prohibit PR enzymatic activities through non-competitive binding to PR, should be sought. Another common feature of current PIs is they were all developed based on the structure-based design. Drugs derived from a structure-based strategy may generate target specific and potent inhibitors. However, this type of drug design can only target one site at a time and drugs discovered by this method are often associated with strong side effects such as cellular toxicity, limiting its number of target choices, efficacy, and applicability. In contrast, a cell-based system may provide a useful alternative strategy that can overcome many of the inherited shortcomings associated with structure-based drug designs. For example, allosteric PIs can be sought using a cell-based system without considering the site or mechanism of inhibition. In addition, a cell-based system can eliminate those PIs that have strong cytotoxic effect. Most importantly, a simple, economical, and easy-to-maintained eukaryotic cellular system such as yeast will allow us to search for potential PIs in a large-scaled high throughput screening (HTS system, thus increasing the chances of success. Based on our many years of experience in using fission yeast as a model system to study HIV-1 Vpr, we propose the use of

Sacco Hospital, Milan, Italy; 5First Division of Infectious Disease, L. Sacco Hospital, Milan, Italy Introduction: Highly active antiretroviral therapy (HAART has allowed many HIV-infected patients to enjoy longer survival and a better quality of life. We performed an economic analysis to estimate the cost-effectiveness of HAART regimens in Italy for managing HIV-naïve infected patients with a viral load below 100,000 copies/mL.Patients and methods: The population considered in the model consisted of adult subjects with an HIV viral load below 100,000 copies/mL who received antiretroviral HAART treatment for the first time, according to the Italian National Guidelines with recommendation grade A1. The incremental cost-effectiveness analysis of quality-adjusted life years (QALYs was carried out by means of a Markov model. Both the outcomes (QALYs and the costs were discounted by 3.5%. The time horizon adopted in the model was 10 years. The point of view of the analysis was that of the Italian national health service.Results: The tenofovir (TDF/emtricitabine (FTC/rilpivirine (RPV single-tablet regimen (STR (€7,417.00 revealed the lowest mean treatment cost. TDF/FTC + raltegravir (RAL showed a better quality of life (0.906 QALY/year, followed by TDF/FTC/RPV (STR; 0.900 QALY/year, TDF/FTC + RPV (multipill regimen (0.889 QALY/year, and TDF/FTC + atazanavir (ATV/r (0.886 QALY/year.

    Full Text Available Background: A high level of adherence is required to achieve the desired outcomes of antiretroviral therapy. There is paucity of information about adherence to combined antiretroviral therapy in Bayelsa State of southern Nigeria. Objectives: The objectives of the study were to determine the level of adherence to combined antiretroviral therapy among the patients, evaluate the improvement in their immune status and identify reasons for sub-optimal adherence to therapy. Methods: The cross-sectional study involved administration of an adapted and pretested questionnaire to 601 consented patients attending the two tertiary health institutions in Bayesla State, Nigeria: The Federal Medical Centre, Yenagoa and the Niger-Delta University Teaching Hospital Okolobiri. The tool was divided into various sections such as socio-demographic data, HIV knowledge and adherence to combined antiretroviral therapy. Information on the patient's CD4+ T cells count was retrieved from their medical records. Adherence was assessed by asking patients to recall their intake of prescribed doses in the last fourteen days and subjects who had 95-100% of the prescribed antiretroviral drugs were considered adherent. Results: Three hundred and forty eight (57.9% of the subjects were females and 253 (42.1% were males. The majority of them, 557 (92.7% have good knowledge of HIV and combined anti-retroviral therapy with a score of 70.0% and above. A larger proportion of the respondents, 441 (73.4%, had ≥95% adherence. Some of the most important reasons giving for missing doses include, “simply forgot” 147 (24.5%, and “wanted to avoid the side-effects of drugs” 33(5.5%. There were remarkable improvements in the immune status of the subjects with an increment in the proportion of the subjects with CD4+ T cells count of greater than 350 cells/mm3 from 33 (5.5% at therapy initiation to 338 (56.3% at study period (p<0.0001. Conclusion: The adherence level of 73.4% was low

    Full Text Available Background: An increase in tuberculosis (TB incidence has been associated with human immunodeficiency virus (HIV. Aims: To describe the clinical characteristics and treatment outcome of patients with HIV and miliary TB treated with short-course intermittent chemotherapy in the absence of access to highly active antiretroviral therapy (HAART. Settings and Design: Prospective study of HIV infected adults referred to a TB clinic between July 1999 and July 2004. Materials and Methods: On diagnosis of miliary TB, patients were treated with a standard regimen of two months of isoniazid, rifampicin, ethambutol and pyrazinamide followed by four months of isoniazid and rifampicin (2EHRZ 3 /4RH 3 thrice weekly and followed up for 24 months. Patients were reviewed clinically every month and two sputa were collected. Chest radiographs and blood investigations were done at two months, end of treatment and every six months thereafter. Results: Of 498 patients with HIV and tuberculosis, 31 (6% were diagnosed as miliary tuberculosis. At diagnosis, sputum smear was positive for acid-fast bacilli (AFB in 14 patients (45% and Mycobacterium tuberculosis was isolated in 21 (68%. The mean CD4 cell count was 129 ± 125 cells/mm 3 . Twenty-five patients were declared cured at the end of treatment (81% while one (3% died and five (16% failed. The recurrence rate was 19.4/100 person-years and the median survival was 17 months (95% CI 14 to 20. None of the patients received antiretroviral therapy. Conclusions: Miliary TB tends to occur among HIV infected patients with severe immunosuppression. Though the initial response to short-course chemotherapy was encouraging, a high recurrence rate and mortality was observed indicating poor prognosis in HIV.

    The effect of directly observed therapy (DOT) versus self-administered therapy (SAT) on antiretroviral (ART) adherence and virological outcomes in prison has never been assessed in a randomized, controlled trial. Prisoners were randomized to receive ART by DOT or SAT. The primary outcome was medication adherence [percent of ART doses measured by the medication event monitoring system (MEMS) and pill counts] at the end of 24 weeks. The changes in the plasma viral loads from baseline and proportion of participants virological suppressed (prisoners declined participation. Participants in the DOT arm (n = 20) had higher viral loads than participants in the SAT (n = 23) arm (p = 0.23). Participants, with complete data at 24 weeks, were analyzed as randomized. There were no significant differences in median ART adherence between the DOT (n = 16, 99% MEMS [IQR 93.9, 100], 97.1 % pill count [IQR 95.1, 99.3]) and SAT (n = 21, 98.3 % MEMS [IQR 96.0, 100], 98.5 % pill count [95.8, 100]) arms (p = 0.82 MEMS, p = 0.40 Pill Count) at 24 weeks. Participants in the DOT arm had a greater reduction in viral load of approximately -1 log 10 copies/mL [IQR -1.75, -0.05] compared to -0.05 [IQR -0.45, 0.51] in the SAT arm (p value = 0.02) at 24 weeks. The proportion of participants achieving virological suppression in the DOT vs SAT arms was not statistically different at 24 weeks (53 % vs 32 %, p = 0.21). These findings suggest that DOT ART programs in prison settings may not offer any additional benefit on adherence than SAT programs. PMID:25055766

    Full Text Available Introduction: As access to prevention of mother-to-child transmission (PMTCT efforts has increased, the total number of children being born with HIV has significantly decreased. However, those children who do become infected after PMTCT failure are at particular risk of HIV drug resistance, selected by exposure to maternal or paediatric antiretroviral drugs used before, during or after birth. As a consequence, the response to antiretroviral therapy (ART in these children may be compromised, particularly when non-nucleoside reverse transcriptase inhibitors (NNRTIs are used as part of the first-line regimen. We review evidence guiding choices of first- and second-line ART. Discussion: Children generally respond relatively well to ART. Clinical trials show the superiority of protease inhibitor (PI- over NNRTI-based treatment in young children, but observational reports of NNRTI-containing regimens are usually favourable as well. This is reassuring as national guidelines often still recommend the use of NNRTI-based treatment for PMTCT-unexposed young children, due to the higher costs of PIs. After failure of NNRTI-based, first-line treatment, the rate of acquired drug resistance is high, but HIV may well be suppressed by PIs in second-line ART. By contrast, there are currently no adequate alternatives in resource-limited settings (RLS for children failing either first- or second-line, PI-containing regimens. Conclusions: Affordable salvage treatment options for children in RLS are urgently needed.

    Full Text Available Abstract The development and widespread clinical use of coformulated abacavir/lamivudine/zidovudine (ABC/3TC/ZDV as Trizivir represented an important advance in the management of HIV-infected patients, especially those with adherence challenges. With a low pill burden, no food restrictions, limited drug-drug interactions, and a favorable resistance profile, ABC/3TC/ZDV remains an alternative option in the US Department of Health and Human Services Consensus Panel Guidelines as initial treatment in antiretroviral-naive patients. Recent data have shown ABC/3TC/ZDV to be less efficacious in suppressing and/or maintaining suppression of virologic replication compared with efavirenz-containing antiretroviral therapy. Although triple-nucleoside/nucleotide reverse transcriptase inhibitor (t-NRTI combinations that do not contain a thymidine analog (ZDV or stavudine have recently shown high virologic failure rates in clinical trials and clinical practice, t-NRTI regimens containing a thymidine analog have consistently been shown to be efficacious.

    Background While there has been a rapid global scale-up of antiretroviral therapy programs over the past decade, there are limited data on long-term outcomes from large cohorts in resource-constrained settings. Our objective in this evaluation was to measure multiple outcomes during first-line antiretroviral therapy in a large treatment program in Nigeria. Methods We conducted a retrospective multi-site program evaluation of adult patients (age ≥15 years) initiating antiretroviral therapy between June 2004 and February 2012 in Nigeria. The baseline characteristics of patients were described and longitudinal analyses using primary endpoints of immunologic recovery, virologic rebound, treatment failure and long-term adherence patterns were conducted. Results Of 70,002 patients, 65.2% were female and median age was 35 (IQR: 29–41) years; 54.7% were started on a zidovudine-containing and 40% on a tenofovir-containing first-line regimen. Median CD4+ cell counts for the cohort started at 149 cells/mm3 (IQR: 78–220) and increased over duration of ART. Of the 70,002 patients, 1.8% were reported as having died, 30.1% were lost to follow-up, and 0.1% withdrew from treatment. Overall, of those patients retained and with viral load data, 85.4% achieved viral suppression, with 69.3% achieving suppression by month 6. Of 30,792 patients evaluated for virologic failure, 24.4% met criteria for failure and of 45,130 evaluated for immunologic failure, 34.0% met criteria for immunologic failure, with immunologic criteria poorly predicting virologic failure. In adjusted analyses, older age, ART regimen, lower CD4+ cell count, higher viral load, and inadequate adherence were all predictors of virologic failure. Predictors of immunologic failure differed slightly, with age no longer predictive, but female sex as protective; additionally, higher baseline CD4+ cell count was also predictive of failure. Evaluation of long-term adherence patterns revealed that the majority of patients

    Background Antiretroviral therapy (ART) decreases mortality risk in HIV-infected tuberculosis patients, but the effect of the duration of anti-tuberculosis therapy and timing of anti-tuberculosis therapy initiation in relation to ART initiation on mortality, is unclear. Methods We conducted a retrospective observational multi-center cohort study among HIV-infected persons concomitantly treated with Rifamycin-based anti-tuberculosis therapy and ART in Latin America. The study population included persons for whom 6 months of anti-tuberculosis therapy is recommended. Results Of 253 patients who met inclusion criteria, median CD4+ lymphocyte count at ART initiation was 64 cells/mm3, 171 (68%) received >180 days of anti-tuberculosis therapy, 168 (66%) initiated anti-tuberculosis therapy before ART, and 43 (17%) died. In a multivariate Cox proportional hazards model that adjusted for CD4+ lymphocytes and HIV-1 RNA, tuberculosis diagnosed after ART initiation was associated with an increased risk of death compared to tuberculosis diagnosis before ART initiation (HR 2.40; 95% CI 1.15, 5.02; P = 0.02). In a separate model among patients surviving >6 months after tuberculosis diagnosis, after adjusting for CD4+ lymphocytes, HIV-1 RNA, and timing of ART initiation relative to tuberculosis diagnosis, receipt of >6 months of anti-tuberculosis therapy was associated with a decreased risk of death (HR 0.23; 95% CI 0.08, 0.66; P=0.007). Conclusions The increased risk of death among persons diagnosed with tuberculosis after ART initiation highlights the importance of screening for tuberculosis before ART initiation. The decreased risk of death among persons receiving > 6 months of anti-tuberculosis therapy suggests that current anti-tuberculosis treatment duration guidelines should be re-evaluated.

    Full Text Available BACKGROUND: An effective therapeutic vaccine that could augment immune control of HIV-1 replication may abrogate or delay the need for antiretroviral therapy. AIDS Clinical Trials Group (ACTG A5187 was a phase I/II, randomized, placebo-controlled, double-blinded trial to evaluate the safety and immunogenicity of an HIV-1 DNA vaccine (VRC-HVDNA 009-00-VP in subjects treated with antiretroviral therapy during acute/early HIV-1 infection. (clinicaltrials.gov NCT00125099 METHODS: Twenty healthy HIV-1 infected subjects who were treated with antiretroviral therapy during acute/early HIV-1 infection and had HIV-1 RNA<50 copies/mL were randomized to receive either vaccine or placebo. The objectives of this study were to evaluate the safety and immunogenicity of the vaccine. Following vaccination, subjects interrupted antiretroviral treatment, and set-point HIV-1 viral loads and CD4 T cell counts were determined 17-23 weeks after treatment discontinuation. RESULTS: Twenty subjects received all scheduled vaccinations and discontinued antiretroviral therapy at week 30. No subject met a primary safety endpoint. No evidence of differences in immunogenicity were detected in subjects receiving vaccine versus placebo. There were also no significant differences in set-point HIV-1 viral loads or CD4 T cell counts following treatment discontinuation. Median set-point HIV-1 viral loads after treatment discontinuation in vaccine and placebo recipients were 3.5 and 3.7 log(10 HIV-1 RNA copies/mL, respectively. CONCLUSIONS: The HIV-1 DNA vaccine (VRC-HIVDNA 009-00-VP was safe but poorly immunogenic in subjects treated with antiretroviral therapy during acute/early HIV-1 infection. Viral set-points were similar between vaccine and placebo recipients following treatment interruption. However, median viral load set-points in both groups were lower than in historical controls, suggesting a possible role for antiretroviral therapy in persons with acute or early HIV-1

    A survey was administered to HIV-infected patients and a sample in Soweto and the Johannesburg inner city to measure preferences for antiretroviral therapy (ART) provision. The 25 to 49-year-old male and female respondents viewed 20 sets of three hypothetical ART clinic choices after reading information on ART. Each set had a permutation of four levels of: monthly ART price, clinic waiting times, HIV clinic branding and clinic staff attitudes. For each set, respondents selected the preferred mix of characteristics and indicated if they would pay for it. For every ZAR 100 (USD PPP 25) increase in price, the average probability of selecting a clinic decreased by 2.8 and 3.0% in the HIV patient and household samples, respectively. Cost as well as staff attitude, wait time, and clinic branding may constitute important barriers to ART uptake and adherence in resource-poor settings. PMID:19533322

    Full Text Available BACKGROUND: In Mozambique during 2004-2007 numbers of adult patients (≥15 years old enrolled on antiretroviral therapy (ART increased about 16-fold, from 60 kg, WHO stage IV (AHR 1.7; 95% CI, 1.3-2.4, reference group WHO stage I/II, lack of co-trimoxazole prescription (AHR 1.4; 95% CI, 1.0-1.8, and later calendar year of ART initiation (AHR 1.5; 95% CI, 1.2-1.8. 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.

    2010-04-01

    Depression and anxiety are common among HIV-infected people and rank among the strongest predictors of non-adherence to antiretroviral therapy (ART). This longitudinal study aimed to assess whether symptoms of anxiety and depression are predictors of non-adherence among patients initiating ART at two public referral centers (n = 293) in Belo Horizonte, Brazil. Prevalence of severe anxiety and depression symptoms before starting ART was 12.6% and 5.8%, respectively. Severe anxiety was a predictor of non-adherence to ART during follow-up period (RH = 1.87; 95% CI = 1.14-3.06) adjusted for low education, unemployment, alcohol use in the last month and symptoms of AIDS; while a history of injection drug use had borderline statistical significance with non-adherence. These findings suggest that using a brief screening procedure to assess anxiety and depression symptoms before initiating ART help identify individuals for interventions to improve adherence and quality of life.

    Haiti is the poorest country in the Western Hemisphere and has the highest number of people living with HIV in the Caribbean, the region most impacted by HIV outside of Africa. Despite continuous political, socioeconomic and natural catastrophes, Haiti has mounted a very successful response to the HIV epidemic. Prevention and treatment strategies implemented by the government in collaboration with non-governmental organizations have been instrumental in decreasing the national HIV prevalence from a high of 6.2% in 1993 to 2.2% in 2012. We describe the history and epidemiology of HIV in Haiti and the expansion of antiretroviral therapy (ART) over the past decade, with the achievement of universal access to ART for patients meeting the 2010 World Health Organization guidelines. We also describe effective models of care, successes and challenges of international funding, and current challenges in the provision of ART. We are optimistic that the goal of providing ART for all in need remains in reach.

    Individuals who are heterozygous for the CCR5-Δ32 mutation provide a natural model to examine the effects of reduced CCR5 expression on human immunodeficiency virus (HIV) persistence. We evaluated the HIV reservoir in 18 CCR5-Δ32 heterozygotes and 54 CCR5 wild-type individuals during suppressive antiretroviral therapy. Cell-associated HIV RNA levels (P=.035), RNA to DNA transcriptional ratios (P=.013), and frequency of detectable HIV 2-long terminal repeat circular DNA (P=.013) were significantly lower in CD4+ T cells from CCR5-Δ32 heterozygotes. Cell-associated HIV RNA was significantly correlated with CCR5 surface expression on CD4+ T cells (r2=0.136; P=.002). Our findings suggest that curative strategies should further explore manipulation of CCR5.

    2010-07-01

    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. Longer pre-ART waiting time (2-12 weeks compared to Conclusion Baseline predictors of poor treatment outcomes were largely unique to each programme, likely reflecting

    Full Text Available Introduction: The costs of combination antiretroviral therapy (cART consisting of separate, particularly generic, components are generally much lower than of a single tablet regimen (STR including the same active ingredients. Our aim was to evaluate whether patients in care in the Netherlands would be willing to take separate component regimens (SCR instead of an STR and to examine whether willingness was associated with particular patient characteristics. Materials and Methods: Data from the HIV Monitoring Foundation of all adult HIV-1-infected patients in care taking cART>6 months were used to randomly select 1000 patients. As part of a questionnaire developed for a study assessing patient experience, patients were asked whether they were willing to take an SCR instead of an STR. Logistic regression was used to examine associations between age, gender, region of origin, mode of HIV transmission, socioeconomic status, duration of cART and answering “yes” to the question versus “maybe” or “no.” Variables with p<0.1 in the univariate analysis were entered in a multivariate model. Results: Of the 300 patients who completed the questionnaire, 49% answered “yes,” 24% “maybe” and 27% “no” to the question whether they would be willing to use a SCR. Reasons for answering “no” included difficulties swallowing pills, convenience of STR (especially when travelling/at work, and concerns about side effects. Respondents who answered “maybe” often indicated that they preferred STRs, emphasized the importance of taking the pills once daily, and pointed out that efficacy/safety of an SCR should not be less. Having to pay for medication was reported as a reason to consider switching to an SCR. In the multivariate analysis, respondents who were born outside the Netherlands were less likely; and those with cART use ≥15 yrs were more likely to answer “yes” (Table 1. Conclusions: Half of the respondents were willing to take SCRs

    Full Text Available Candidia esophagitis (CE is an AIDS-defining condition, usually occurring in individuals with low CD4 counts of <200 cells/µL. Endoscopy is a valuable definitive diagnostic method for CE but may not be indicated for asymptomatic patients or for those with high CD4 counts or without oral candidiasis. This study assessed such patients to clarify the factors associated with CE and its severity on endoscopy in the highly active antiretroviral therapy (HAART era.A total of 733 HIV-infected patients who underwent upper gastrointestinal (GI endoscopy were analyzed. Sexual behavior, CD4(+ count, HIV-RNA viral load (VL, history of HAART, GI symptoms, GI diseases, and oral candidiasis were assessed. Endoscopic severity of CE was classified as mild (Kodsi's grade I/II or severe (grade III/IV. Of the 733 subjects, 62 (8.46% were diagnosed with CE (mild, n = 33; severe, n = 29. Of them, 56.5% (35/62 had no GI symptoms, 30.6% (19/62 had CD4 + ≥200 cells/μL, and 55.3% (21/38 had no oral candidiasis. Univariate analysis found lower CD4+ counts, higher HIV VL, and no history of HAART to be significantly associated with CE. With lower CD4(+ counts and higher HIV VL, CE occurrence increased significantly (P<0.01 for trend in odds. Multivariate analysis showed low CD4+ counts and high HIV VL to be independently associated with CE. Of the severe CE patients, 55.2% (16/29 had no GI symptoms and 44.4% (8/18 had no oral candidiasis. Median CD4(+ counts in severe cases were significantly lower than in mild cases (27 vs. 80; P = 0.04.Low CD4+ counts and high HIV VL were found to be factors associated with CE, and advanced immunosuppression was associated with the development of severity. Endoscopy is useful as it can detect CE, even severe CE, in patients without GI symptoms, those with high CD4 counts, and those without oral candidiasis.

    Full Text Available The objective of the present study was to evaluate the duodenal mucosa of HIV-infected patients during antiretroviral therapy. This was an observational study conducted on HIV-positive patients and a control group. Group 1 comprised 22 HIV-negative individuals while 38 HIV-positive individuals were classified according to the CDC 1993 classification into group 2 (A1 or A2 or group 3 (B2, A3, B3, C2, C3. All subjects were submitted to upper gastrointestinal endoscopy with duodenal biopsies. Qualitative, semi-quantitative and quantitative histological analyses were performed. Results were considered significant when P < 0.05. A higher prevalence of inflammatory infiltrate and eosinophilia was observed in the HIV group, together with a reduction in mucosal CD4+ lymphocyte (L counts [median (lower-upper quartiles, 12.82 (8.30-20.33, 6.36 (1.75-11.66 and 1.75 (0.87-3.14 in groups 1, 2 and 3, respectively] which was not correlated with disease stage. The extent of CD4+L count reduction was similar in blood and duodenal mucosa. Normal CD8+L and CD45RO+L counts, and normal numbers of macrophages and antigen-presenting cells were also found in the HIV patients. The cytokine pattern did not differ among groups. Tissue HIV, assessed by p24 antigen, correlated with a higher CD45RO+L count (77.0 (61-79.8 and 43.6 (31.7-62.8 in p24+ and p24-, respectively, P = 0.003, and IL-4 positivity (100 and 48.2% in p24+ and p24-, respectively, P = 0.005. The duodenal mucosa of HIV+ patients showed a relatively preserved histological architecture. This finding may be characteristic of a population without opportunistic infections and treated with potent antiretroviral therapy, with a better preservation of the immune status.

    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.

  13. Long-term costs and health impact of continued global fund support for antiretroviral therapy.

    John Stover

    Full Text Available BACKGROUND: By the end of 2011 Global Fund investments will be supporting 3.5 million people on antiretroviral therapy (ART in 104 low- and middle-income countries. We estimated the cost and health impact of continuing treatment for these patients through 2020. METHODS AND FINDINGS: Survival on first-line and second-line ART regimens is estimated based on annual retention rates reported by national AIDS programs. Costs per patient-year were calculated from country-reported ARV procurement prices, and expenditures on laboratory tests, health care utilization and end-of-life care from in-depth costing studies. Of the 3.5 million ART patients in 2011, 2.3 million will still need treatment in 2020. The annual cost of maintaining ART falls from $1.9 billion in 2011 to $1.7 billion in 2020, as a result of a declining number of surviving patients partially offset by increasing costs as more patients migrate to second-line therapy. The Global Fund is expected to continue being a major contributor to meeting this financial need, alongside other international funders and domestic resources. Costs would be $150 million less in 2020 with an annual 5% decline in first-line ARV prices and $150-370 million less with a 5%-12% annual decline in second-line prices, but $200 million higher in 2020 with phase out of stavudine (d4T, or $200 million higher with increased migration to second-line regimens expected if all countries routinely adopted viral load monitoring. Deaths postponed by ART correspond to 830,000 life-years saved in 2011, increasing to around 2.3 million life-years every year between 2015 and 2020. CONCLUSIONS: Annual patient-level direct costs of supporting a patient cohort remain fairly stable over 2011-2020, if current antiretroviral prices and delivery costs are maintained. Second-line antiretroviral prices are a major cost driver, underscoring the importance of investing in treatment quality to improve retention on first-line regimens.

    Antiretroviral therapy has significantly evolved in the last decade, with an increasing number of new drugs and classes. Currently, even heavily experienced patients can be successfully treated with new regimens. In Brazil, the recent incorporation of some new antiretroviral drugs made it possible to suppress HIV plasma viremia in most treated patients, with significant benefits in terms of quality of life and survival. However, little has been published on outcomes of patients under new drugs-based regimens. We reviewed the safety and efficacy of antiretroviral regimens using recently introduced drugs in Bahia. Our results confirm that patients using darunavir, raltegravir, enfuvirtide, or etravirine presented with a high rate of virological suppression without significant adverse events, after one year of follow-up.

    Improved survival achieved by many patients with HIV/AIDS has complicated their medical care as increasing numbers of co-morbidities leads to polypharmacy, increased pill burdens, and greater risks of drug-drug interactions potentially compromising antiretroviral treatment (ART). We examined the impact of non-antiretroviral polypharmacy on ART for all adults followed at the Southern Alberta Clinic, Calgary, Canada. Polypharmacy was defined as ≥5 daily medications. We compared the impact of polypharmacy on continuous (i.e., remaining on same ART for ≥6 months) vs. non-continuous (i.e., discontinuing or switching ART) ART dosing frequency, number of ART pills, number of non-ART medications, and age. Of 1190 (89.5%) patients on ART, 95% were on three-drug regimens, 63.9% on QD ART, and 62% ≥3 ART pills daily; 32.2% were experiencing polypharmacy. Polypharmacy was associated with lower CD4, AIDS, >180 months living with HIV, higher numbers of ART pills, and older age (all p Polypharmacy increased the risk for non-continuous ART (36.8% vs. 30.0%; p age. Non-adherence and adverse effects accounted for the majority of non-continuous ART. We found a strong association between polypharmacy and non-continuous ART, potentially leading to effective ART being compromised. Collaborative approaches are needed to anticipate the negative impacts of polypharmacy. PMID:26544766

    Full Text Available Despite the effectiveness of combination antiretroviral therapy in the treatment of people living with HIV/AIDS (PLWHA, nonadherence to medication has become a major threat to its effectiveness. This study aimed to estimate the prevalence of self-reported irregular use of antiretroviral therapy and the factors associated with such an irregularity in PLWHA. A cross-sectional study of PLWHA who attended two referral centers in the city of Recife, in Northeastern Brazil, between June 2007 and October 2009 was carried out. The study analyzed socioeconomic factors, social service support and personal habits associated with nonadherence to antiretroviral therapy, adjusted by multivariable logistic regression analysis. The prevalence of PLWHA who reported irregular use of combination antiretroviral therapy (cART was 25.7%. In the final multivariate model, the irregular use of cART was associated with the following variables: being aged less than 40 years (OR = 1.66, 95%-CI: 1.29-2.13, current smokers (OR = 1.76, 95%-CI: 1.31-2.37 or former smokers (OR = 1.43, 95%-CI: 1.05-1.95, and crack cocaine users (OR = 2.79, 95%-CI: 1.24-6.32. Special measures should be directed towards each of the following groups: individuals aged less than 40 years, smokers, former smokers and crack cocaine users. Measures for giving up smoking and crack cocaine should be incorporated into HIV-control programs in order to promote greater adherence to antiretroviral drugs and thus improve the quality of life and prolong life expectancy.

Methods Epidemiological characteristics of AIDS patients failing in HAART were investigated. CD4+T lymphocyte count and viral load were detected, and HIV-1 resistance testing was conducted on those patients with viral load more than 1000 copies/ml. Results Among 66 patients failing in HAART, drug resistance mutations were found in 53 patients. The most common nucleoside reverse transcriptase inhibitor resistance mutations were M184V, D67N and K70R, and non-nucleoside reverse transcriptase inhibitor resistance mutations were K103N, G190A and V179D. Only 3 protease inhibitor (P I ) resistance mutations were found, and they were D33F, M46I and L76V, respectively. Conclusions The emergence of reverse transcriptase resistance mutations is the main reason for the failure of first-line antiretroviral therapy (ART) in AIDS patients in Lincang, Yunnan province. Therefore, when switching to second-line ART, the increased use of PI can avoid ART failure due to multidrug resistance.

The comparisons were performed with the help of a Markov decision model over a 10-year time horizon. Based on the ADONE (ADherence to ONE pill study, it was then possible to identify the utility score increment in patients switching from a multipill regimen of TDF-FTC + EFV therapy to a single-tablet regimen.Results: The single-tablet regimen (0.755 quality-adjusted life-years [QALYs]/year resulted in better patient quality of life, with a higher number of QALYs than for the TDF-FTC + EFV multipill regimen (0.716 QALYs/year. The single-tablet regimen was the most cost-effective treatment strategy, with an incremental cost-effectiveness ratio of €22,017.00 versus €26,558.00 for the multipill regimen. A 24% decrease in cost of the multipill regimen determined equivalence with the single-tablet regimen in terms of the incremental cost-effectiveness ratio. Univariate sensitivity and probabilistic analysis carried out on the main variables did not highlight significant variations with respect to the base case scenario.Conclusion: The single-tablet regimen resulted in better adherence, and therefore better quality of life as perceived by patients, corresponding to a €4541.00 lower

    Objective:To investigate the prevalence of use of traditional medicines amongst patients with HIV infection receiving therapies of antiretroviral(ARV) drugs at the Aminu Kano Teaching Hospital(AKTH), Kano, Northwest Nigeria, and to assess the attitude of these patients to theirARV therapy.Methods: A cross sectional prospective study using pretested structured questionnaires administered on430 patients with antiretroviral therapy attending the AKTH between April and June2009. Data was collected on socio-demographic characteristics, use of traditional medicine and attitude to antiretroviral therapy.Results: A mean age of(33.6±8.4)years old was found with67.2% females and32.8% males. A total of29% had no formal education while 10.5% had postgraduate education;12% earned above 35 000 naira (230 USD) per month;63.8% were married;39.8% had at least2 sexual partners; 27.5% used traditional medicine before commencement of antiretroviral therapy (ART), but only4.25% of patients used ARV and traditional medicine concurrently. There was no significant difference in most of the socio-demographic indices between the concurrent users and other patients (P>0.05). A total of 28.8% HIV patients,14.6% patients used traditional medicine beforeART and29.4% concurrent users had missed at least a dose of theirARVs since commencement of therapy. 148 (37%) of the patients had their drug regimen changed at least once while23 (20.90%) patients receiving traditional medicine beforeARTand5 (29.41%) patients having two treatments had their drug regimen changed.Conclusions: A total of4.25% patients used ARV and traditional medicine concurrently. In conclusion, the widespread use of traditional medicine by patients living with HIV/AIDSshould be of concern to clinicians and policy makers.

    L-697,661 is a non-nucleoside analogue with potent, selective inhibitory activity against the reverse transcriptase of human immunodeficiency virus type 1 (HIV-1). The present study evaluated the potential role of this compound in the treatment of HIV-1-infected patients in a double-blinded, placebo- and zidovudine-controlled trial using plasma viremia as a marker of antiviral activity and real-time phenotypic evaluation of viral isolates for the emergence of resistance. Participants received 12 weeks of either placebo, 25 mg twice a day, 100 mg three times a day, or 500 mg twice a day of L-697,661, or zidovudine, 100 mg five times a day. Mean logarithmic reciprocal titers of plasma virus in patients taking either L-697,661 or zidovudine decreased by week 4 of therapy; for L-697,661 recipients these changes were dose-dependent and, at the highest dose tested, were comparable in magnitude to those seen with zidovudine. Viral suppression induced by L-697,661 persisted through 8 weeks of treatment but decreased by week 12. This rebound paralleled emergence of viral isolates showing resistance to L-697,661. We conclude that although L-697,661 has potent antiretroviral activity in vivo, its utility may be compromised by rapid emergence of L-697,661-resistant virus. Plasma viremia is a highly sensitive technique affording considerable utility in the early testing of such agents. PMID:8516307

They may represent a simplification strategy in patients with persistently suppressed human immunodeficiency virus (HIV) viremia, with the main benefits of reducing drug-related toxicities and costs. Systemic virological efficacy of LDR is slightly lower as compared with combined antiretroviral therapy (cART), but patients with failure do not usually develop drug resistance and resuppress HIV replication after reintensification. A major concern of LDR is the lower efficacy in the virus reservoirs, especially in the central nervous system (CNS), where viral compartmentalization and independent evolution of infection may lead to CNS viral escape, often associated with neurologic symptoms. The authors reviewed studies of virological and functional CNS efficacy of LDR, particularly of boosted PI monotherapy regimens, for which more information is available. Symptomatic viral CSF escape was observed mainly in PI/r monotherapy patients with plasma failure and low nadir CD4+ cell counts, and resolved upon reintroduction of triple drug cART, whereas asymptomatic viral failure in CSF was not significantly more frequent in patients on PI/r monotherapy compared with patients on standard cART. In addition, there was no difference in functional outcomes between PI monotherapy and cART patients, irrespective of CSF viral escape. More data are needed on the CNS effect of dual ART regimens and, in general, on long-term efficacy of LDR. Simplification with LDR may be an attractive option in patients with suppressed viral load, if they are well selected and monitored for potential CNS complications.

    In 2003, the Chinese Government initiated a free antiretroviral therapy (ART) program focusing on adult AIDS patients. Pediatric antiretroviral (ARV) formulations were yet unavailable. It was not until July 2005, with the initiation of a two-stage program implemented by the Chinese Ministry of Health, that pediatric formulations became accessible in China. Initially, the pediatric ART program was piloted in six provinces with the highest incidences of pediatric HIV/AIDS. The pilot stage allowed the Chinese Center for Disease Control and Prevention (CCDC) to finalize entry criteria, treatment regimen, and patient monitoring and follow-up procedures. The second stage commenced at the end of 2006 when the program was scaled-up nationally. In order to guarantee treatment of pediatric patients, extensive training in the selection of appropriate ARV drug regimen and dosage was provided to doctors, often through on-site collaboration with domestic and international experts. The CCDC simultaneously established a pediatric ARV management system and a pediatric ART information system. CD4 count and other laboratory tests are being routinely performed on these pediatric patients. By the end of June 2009, 1529 pediatric patients had received ARV under the national program. However, challenges remain. Firstly, many children infected with HIV/AIDS live in rural areas where the treatment quality is hindered by the limited number of medical facilities and skilled medical workers. Secondly, much of the pediatric ARV drug supply depends on donation. An effort needs to be made by the Chinese Government to establish China's own drug procurement and supply system.

    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

    With millions in need of HIV antiretroviral therapy (ART) in the developing world, and scarce human and fiscal resources available, we conducted a formative evaluation of scale-up operations at clinics associated with AIDS Healthcare Foundation in Africa to identify lessons learned for improving scale-up efficiency. Site visits were made to six selected clinics in Uganda, Zambia, and South Africa, during which semistructured interviews with key stake-holders and observation of client flows and clinic operations were performed. This evaluation revealed the following lessons related to factors that are critical to efficient ART scale-up: (1) to ensure steady ART uptake, it is important to involve the community and community leaders in outreach, HIV education, and program decision-making; (2) minimizing bottlenecks to smooth patient flow requires efficient staff allocation to appropriate clinical duties, streamlined clinic visit schedule protocols, and tapping clients and the HIV community as a key source of labor; (3) to minimize clients dropping out of care, structures should be developed that enable clients to provide support and a "safety net" for helping each other remain in care; (4) computerized record management systems are essential for accurate antiretroviral inventory and dispensing records, quality assurance monitoring, and client enrollment records and visit scheduling; (5) effective organizational management and human resource policies are essential to maintain high job performance and satisfaction and limit burnout; (6) to maximize impact on social and economic health, it is important for ART programs to develop effective mechanisms for coordinating and referring clients to support service organizations.

    Ethnopharmacological relevance A substantial proportion of the population in Papua New Guinea (PNG) lives with human immunodeficiency virus (HIV). Treatment requires lifelong use of antiretroviral therapy (ART). The majority of people in PNG use traditional medicines (TM) derived from plants for all types of health promotions. Consequently, there is a concern that herb-drug interactions may impact the efficacy of ART. Herb-drug, or drug-drug, interactions occur at the level of metabolism through two major mechanisms: enzyme induction or enzyme inhibition. In this study, extracts of commonly-used medicinal plants from PNG were screened for herb-drug interactions related to cytochrome P450s (CYPs). Materials and Methods Sixty nine methanol extracts of TM plants were screened for their ability to induce CYPs by human aryl hydrocarbon receptor- (hAhR-) and human pregnane X receptor- (hPXR-) dependent mechanisms, utilizing a commercially available cell-based luciferase reporter system. Inhibition of three major CYPs, CYP1A2, CYP3A4, and CYP2D6, was determined using human liver microsomes and enzyme-selective model substrates. Results Almost one third of the TM plant extracts induced the hAhR-dependent expression of CYP1A2, the hPXR-dependent expression of CYP3A4, or both. Almost two thirds inhibited CYP1A2, CYP3A4, or CYP2D6, or combinations thereof. Many plant extracts exhibited both induction and inhibition properties. Conclusions We demonstrated that the potent and selective ability of extracts from PNG medicinal plants to affect drug metabolizing enzymes through induction and/or inhibition is a common phenomenon. Use of traditional medicines concomitantly with ART could dramatically alter the concentrations of antiretroviral drugs in the body; and their efficacy. PNG healthcare providers should counsel HIV patients because of this consequence. PMID:25138353

    Full Text Available As antiretroviral therapy (ART for HIV becomes increasingly available in low and middle income countries (LMICs, understanding reasons for lack of adherence is critical to stemming the tide of infections and improving health. Understanding the effect of psychosocial experiences and mental health symptomatology on ART adherence can help maximize the benefit of expanded ART programs by indicating types of services, which could be offered in combination with HIV care.The Coping with HIV/AIDS in Tanzania (CHAT study is a longitudinal cohort study in the Kilimanjaro Region that included randomly selected HIV-infected (HIV+ participants from two local hospital-based HIV clinics and four free-standing voluntary HIV counselling and testing sites. Baseline data were collected in 2008 and 2009; this paper used data from 36 month follow-up interviews (N = 468. Regression analyses were used to predict factors associated with incomplete self-reported adherence to ART.Incomplete art adherence was significantly more likely to be reported amongst participants who experienced a greater number of childhood traumatic events: sexual abuse prior to puberty and the death in childhood of an immediate family member not from suicide or homicide were significantly more likely in the non-adherent group and other negative childhood events trended toward being more likely. Those with incomplete adherence had higher depressive symptom severity and post-traumatic stress disorder (PTSD. In multivariable analyses, childhood trauma, depression, and financial sacrifice remained associated with incomplete adherence.This is the first study to examine the effect of childhood trauma, depression and PTSD on HIV medication adherence in a low income country facing a significant burden of HIV. Allocating spending on HIV/AIDS toward integrating mental health services with HIV care is essential to the creation of systems that enhance medication adherence and maximize the potential of

    Background The optimal time to initiate antiretroviral therapy (ART) in human immunodeficiency virus (HIV)–associated tuberculous meningitis is unknown. Methods We conducted a randomized, double-blind, placebo-controlled trial of immediate versus deferred ART in patients with HIV-associated tuberculous meningitis to determine whether immediate ART reduced the risk of death. Antiretroviral drugs (zidovudine, lamivudine, and efavirenz) were started either at study entry or 2 months after randomization. All patients were treated with standard antituberculosis treatment, adjunctive dexamethasone, and prophylactic co-trimoxazole and were followed up for 12 months. We conducted intention-to-treat, per-protocol, and prespecified subgroup analyses. Results A total of 253 patients were randomized, 127 in the immediate ART group and 126 in the deferred ART group; 76 and 70 patients died within 9 months in the immediate and deferred ART groups, respectively. Immediate ART was not significantly associated with 9-month mortality (hazard ratio [HR], 1.12; 95% confidence interval [CI], .81–1.55; P = .50) or the time to new AIDS events or death (HR, 1.16; 95% CI, .87–1.55; P = .31). The percentage of patients with severe (grade 3 or 4) adverse events was high in both arms (90% in the immediate ART group and 89% in the deferred ART group; P = .84), but there were significantly more grade 4 adverse events in the immediate ART arm (102 in the immediate ART group vs 87 in the deferred ART group; P = .04). Conclusions Immediate ART initiation does not improve outcome in patients presenting with HIV-associated tuberculous meningitis. There were significantly more grade 4 adverse events in the immediate ART arm, supporting delayed initiation of ART in HIV-associated tuberculous meningitis.

    Full Text Available Abstract Background Abacavir has been associated with an increased risk of acute myocardial infarction, but the pathogenic mechanisms remain unknown. We evaluated longitudinal changes in pro-atherosclerotic biomarkers in patients initiating abacavir or tenofovir. Methods Consecutive patients initiating antiretroviral therapy (ART with abacavir/lamivudine or tenofovir/emtricitabine were included. Plasma levels of high sensitivity C reactive protein (hsCRP, interleukin-6 (IL-6, intercellular adhesion molecule-1, vascular cell adhesion molecule-1 (sVCAM-1 and plasminogen activator inhibitor-1 (PAI-1 were measured at baseline and at different time points throughout 48 weeks. Comparisons were adjusted for age, sex, ART status at inclusion, viral load, lipodystrophy, Framingham score and hepatitis C virus co-infection status. Results 50 patients were analyzed, 28 initiating abacavir and 22 tenofovir. The endothelial biomarker sVCAM-1 declined significantly in both treatment groups. hsCRP tended to increase soon after starting therapy with abacavir, a trend that was not seen in those initiating tenofovir. IL-6 significantly increased only at week 24 from baseline in patients on abacavir (+225%, p Conclusion Changes in biomarkers of inflammation, coagulation, and endothelial function are not different in viremic patients starting ART with abacavir/lamivudine or tenofovir/emtricitabine. These changes occur in the early phases of treatment and include anti- and pro-atherosclerotic effects with both drugs.

    2012-03-01

    Full Text Available The introduction of antiretroviral therapy (ART has substantially modified the clinical history and epidemiology of HIV infection with an important decline in infective causes of death and an increase in non-infective comorbidities particularly in cardiovascular complications. HIV infection has been related to an increased cardiovascular risk due to the presence of three factors: classic cardiovascular risk factors (shared with the general population, HIV infection itself (indirectly due to the inflammation and directly due to viral molecule and ART-related chronic metabolic alterations. We describe a peculiar case of metabolic alteration in an HIV infected patient on ART with particular attention to the diagnosis and therapeutic aspects. Giving the higher cardiovascular risk of this specific population it is advisable that the clinician performs a frequent re-assessment of risk factors and cardiovascular organ damage. An early detection of metabolic alteration must lead to an aggressive specific therapy; this must be done by taking care of the HIV-infected subject fragility and the interactions with ART.

    Background There is limited evidence on the effect of injectable contraception on response to antiretroviral therapy (ART). Design Using modified Poisson regression, we assessed data from 418 female Ugandan ART initiators to examine the effect of injectable contraceptive use on a composite virologic failure outcome (defined as failure to achieve virologic suppression, switch to second line therapy, or death within 12 months of ART initiation), and also assessed ART adherence. Results About 12% of women reported using injectable contraceptives at ART initiation, and their composite virologic failure rates 12 months later were similar to women not using injectable contraceptives at ART initiation (11% vs. 12%, p=0.99). Multivariable Poisson regression suggested no significant differences in virologic failure by injectable contraceptive use at baseline (PRR: 0.85, p=0.71), but power was limited. Adherence to ART increased with time since ART initiation, but did not appear to differ between injectable contraceptive users and non-users. Conclusions Consistent with current WHO guidelines, our results suggest no deleterious effect of injectable contraceptive use on response to ART, but power was limited, injectable contraceptive use patterns over time were inconsistent, and additional evidence is needed.

    2016-01-01

    The Initiation of Antiretroviral Therapy in Early Asymptomatic HIV Infection (START) study has reinforced the benefits of early initiation of antiretroviral therapy (ART). However, a notable secondary finding from that study was that immediate initiation of ART did not prevent cardiovascular disease (CVD) events (0.17 vs 0.20 events/1000 person-years, P = .65). This result appears to contradict a body of evidence, most notably from the Strategies for Management of Antiretroviral Therapy (SMART) study, which reported a 70% increased hazard of cardiovascular events for those deferring or interrupting treatment. Thus, an important unresolved question is whether the timing of ART impacts CVD risk. In this review, published data on relationships between timing of ART and CVD risk are reviewed. The data support a role for ART in mitigating CVD risk at lower CD4 counts, but data also suggests that, among those initiating therapy early, ART alone appears to suboptimally mitigate CVD risk. Additional interventions to address CVD risk among human immunodeficiency virus-infected populations are likely to be needed. PMID:26989755

    Objective To observe the dynamic changes of interlukin 17 (IL-17) in HIV/AIDS patients with or without highly active antiretrovival therapy (HAART). Methods Peripheral blood samples were collected from 30 normal volunteers and 33 HIV/AIDS patients received HAART. ELISA was used to determine IL -17 levels in sera and the results were compared. At the time points of ore - therapy, 6th month and 12th month of therapy, IL - 17 levels in sera were tested by ELISA, and the dynamic changes of IL -17 levels were compared and analyzed. The flow cytometer was used to count CD4* T- cells and quantitative real-time RT-PCR was used to determine HIV RNA in blood. Results The levels of IL-17 in HIV/AIDS patients at the time points of pre - therapy, 6th month and 12th month of therapy and in the normal volunteers were (5.3±2.5) pg/ml, (7.7±2.4) pg/ml, (10.4±3.1) pg/ml and (17.7±6.6) pg/ml, respectively. The levels of IL -17 were positively correlated with CO4+ T - cell counts, but negatively correlated with HIV viral load. Conclusions The results indicate that IL-17 may play an important role in the pathogenesis of AIDS, and likely to be one of the effective indexes for observing AIDS progress and efficacy of HAART.%目的 观察HIV感染者和AIDS患者(HIV/AIDS)的血清白细胞介素-17(IL-17)水平与正常入水平的区别,及其在接受抗病毒治疗一年中的动态变化. 方法 采集33例HIV/AIDS和30例健康志愿者的静脉血清,以酶联免疫吸附法(ELISA)分别检测其IL- 17水平并对比分析,并在33例HIV/AIDS接受高效抗反转录病毒治疗(HAART)的0、6、12月时分别采集静脉血,同法检测血清IL- 17动态水平并对比分析.以流式细胞计数法检测CD4+细胞数,以real- time RT - PCR法定量检测HIVRNA. 结果 HIV/AIDS在接受HAART治疗前、治疗6月、12月及正常人静脉血IL- 17水平分别为(5.3±2.5)、(7.7±2.4)、(10.4±3.1)和(17.7±6.60)pg/ml; IL-17水平与CD4+T细胞计数正

    Full Text Available BACKGROUND: To date, antiretroviral therapy (ART guidelines and programs in resource-limited settings (RLS have focused on 1(st- and 2(nd-line (2 L therapy. As programs approach a decade of implementation, policy regarding access to 3(rd-line (3 L ART is needed. We aimed to examine the impact of maintaining patients on failing 2 L ART on the accumulation of protease (PR mutations. METHODS AND FINDINGS: From 2004-2011, the Harvard/APIN PEPFAR Program provided ART to >100,000 people in Nigeria. Genotypic resistance testing was performed on a subset of patients experiencing 2 L failure, defined as 2 consecutive viral loads (VL>1000 copies/mL after ≥6 months on 2 L. Of 6714 patients who received protease inhibitor (PI-based ART, 673 (10.0% met virologic failure criteria. Genotypes were performed on 61 samples. Patients on non-suppressive 2 L therapy for 24 months. Patients developed a median of 0.6 (IQR: 0-1.4 IAS PR mutations per 6 months on failing 2 L therapy. In 38% of failing patients no PR mutations were present. For patients failing >24 months, high- or intermediate-level resistance to lopinavir and atazanavir was present in 63%, with 5% to darunavir. CONCLUSIONS: This is the first report assessing the impact of duration of non-suppressive 2 L therapy on the accumulation of PR resistance in a RLS. This information provides insight into the resistance cost of failing to switch non-suppressive 2 L regimens and highlights the issue of 3 L access.

    We study a cellular automata model to test the timing of antiretroviral therapy strategies for the dynamics of infection with human immunodeficiency virus (HIV). We focus on the role of virus diffusion when its population is included in previous cellular automata model that describes the dynamics of the lymphocytes cells population during infection. This inclusion allows us to consider the spread of infection by the virus-cell interaction, beyond that which occurs by cell-cell contagion. The results show an acceleration of the infectious process in the absence of treatment, but show better efficiency in reducing the risk of the onset of AIDS when combined antiretroviral therapies are used even with drugs of low effectiveness. Comparison of results with clinical data supports the conclusions of this study.

    Full Text Available BACKGROUND: Non-AIDS conditions such as cardiovascular disease and non-AIDS defining cancers dominate causes of morbidity and mortality among persons with HIV on suppressive combination antiretroviral therapy. Accurate estimates of disease incidence and of risk factors for these conditions are important in planning preventative efforts. METHODS: With use of medical records, serious non-AIDS events, AIDS events, and causes of death were adjudicated using pre-specified criteria by an Endpoint Review Committee in two large international trials. Rates of serious non-AIDS which include cardiovascular disease, end-stage renal disease, decompensated liver disease, and non-AIDS cancer, and other serious (grade 4 adverse events were determined, overall and by age, over a median follow-up of 4.3 years for 3,570 participants with CD4+ cell count ≥300 cells/mm³ who were taking antiretroviral therapy and had an HIV RNA level ≤500 copies/mL. Cox models were used to examine the effect of age and other baseline factors on risk of a composite outcome of all-cause mortality, AIDS, or serious non-AIDS. RESULTS: Five-year Kaplan-Meier estimates of the composite outcome, overall and by age were 8.3% (overall, 3.6% (<40, 8.7% (40-49 and 16.1% (≥50, respectively (p<0.001. In addition to age, smoking and higher levels of interleukin-6 and D-dimer were significant predictors of the composite outcome. The composite outcome was dominated by serious non-AIDS events (overall 65% of 277 participants with a composite event. Most serious non-AIDS events were due to cardiovascular disease and non-AIDS cancers. CONCLUSIONS: To date, few large studies have carefully collected data on serious non-AIDS outcomes. Thus, reliable estimates of event rates are scarce. Data cited here, from a geographically diverse cohort, will be useful for planning studies of interventions aimed at reducing rates of serious non-AIDS events among people with HIV.

Of the global total number of adolescents living with HIV in 2013, 83% reside in sub-Saharan Africa. The study aimed to identify facilitators of and barriers to antiretroviral treatment adherence among adolescents in Ghana. Methods: A cross-sectional qualitative study using semi-structured interviews for data collection was carried out among adolescents (aged 12–19 years at the adolescents HIV clinic at the Korle-Bu Teaching Hospital in Ghana. Predominantly open-ended questions relating to ART were used. Interviews were done until saturation. In total, 19 interviews were conducted. Analysis was done manually to maintain proximity with the text. Findings: The main facilitators were support from health care providers, parental support, patient’s knowledge of disease and self-motivation, patient’s perceived positive outcomes, and dispensed formulation. The identified barriers were patient’s forgetfulness to take medicines, perceived stigmatization due to disclosure, financial barriers, and adverse effects of ART. Support from health care workers was the most frequently mentioned facilitator, and patient’s forgetfulness and perceived

    Full Text Available Knowledge of tuberculosis incidence and associated factors is required for the development and evaluation of strategies to reduce the burden of HIV-associated tuberculosis.Systematic literature review and meta-analysis of tuberculosis incidence rates among HIV-infected individuals taking combination antiretroviral therapy.From PubMed, EMBASE and Global Index Medicus databases, 42 papers describing 43 cohorts (32 from high/intermediate and 11 from low tuberculosis burden settings were included in the qualitative review and 33 in the quantitative review. Cohorts from high/intermediate burden settings were smaller in size, had lower median CD4 cell counts at study entry and fewer person-years of follow up. Tuberculosis incidence rates were higher in studies from Sub-Saharan Africa and from World Bank low/middle income countries. Tuberculosis incidence rates decreased with increasing CD4 count at study entry and duration on combination antiretroviral therapy. Summary estimates of tuberculosis incidence among individuals on combination antiretroviral therapy were higher for cohorts from high/intermediate burden settings compared to those from the low tuberculosis burden settings (4.17 per 100 person-years [95% Confidence Interval (CI 3.39-5.14 per 100 person-years] vs. 0.4 per 100 person-years [95% CI 0.23-0.69 per 100 person-years] with significant heterogeneity observed between the studies.Tuberculosis incidence rates were high among individuals on combination antiretroviral therapy in high/intermediate burden settings. Interventions to prevent tuberculosis in this population should address geographical, socioeconomic and individual factors such as low CD4 counts and prior history of tuberculosis.

    In Cuba, antiretroviral therapy rollout started in 2001 and antiretroviral therapy coverage has reached almost 40% since then. The objectives of this study were therefore to analyze subtype distribution, and level and patterns of drug resistance in therapy-naive HIV-1 patients. Four hundred and one plasma samples were collected from HIV-1 therapy-naive patients in 2003 and in 2007-2011. HIV-1 drug resistance genotyping was performed in the pol gene and drug resistance was interpreted according to the WHO surveillance drug-resistance mutations list, version 2009. Potential impact on first-line therapy response was estimated using genotypic drug resistance interpretation systems HIVdb version 6.2.0 and Rega version 8.0.2. Phylogenetic analysis was performed using Neighbor-Joining. The majority of patients were male (84.5%), men who have sex with men (78.1%) and from Havana City (73.6%). Subtype B was the most prevalent subtype (39.3%), followed by CRF20-23-24_BG (19.5%), CRF19_cpx (18.0%) and CRF18_cpx (10.3%). Overall, 29 patients (7.2%) had evidence of drug resistance, with 4.0% (CI 1.6%-4.8%) in 2003 versus 12.5% (CI 7.2%-14.5%) in 2007-2011. A significant increase in drug resistance was observed in recently HIV-1 diagnosed patients, i.e. 14.8% (CI 8.0%-17.0%) in 2007-2011 versus 3.8% (CI 0.9%-4.7%) in 2003 (OR 3.9, CI 1.5-17.0, p=0.02). The majority of drug resistance was restricted to a single drug class (75.8%), with 55.2% patients displaying nucleoside reverse transcriptase inhibitor (NRTI), 10.3% non-NRTI (NNRTI) and 10.3% protease inhibitor (PI) resistance mutations. Respectively, 20.7% and 3.4% patients carried viruses containing drug resistance mutations against NRTI+NNRTI and NRTI+NNRTI+PI. The first cases of resistance towards other drug classes than NRTI were only detected from 2008 onwards. The most frequent resistance mutations were T215Y/rev (44.8%), M41L (31.0%), M184V (17.2%) and K103N (13.8%). The median genotypic susceptibility score for the

  4. Food insecurity as a barrier to sustained antiretroviral therapy adherence in Uganda.

    Directory of Open Access Journals (Sweden)

    Sheri D Weiser

    Full Text Available BACKGROUND: Food insecurity is emerging as an important barrier to antiretroviral (ARV adherence in sub-Saharan Africa and elsewhere, but little is known about the mechanisms through which food insecurity leads to ARV non-adherence and treatment interruptions. METHODOLOGY: We conducted in-depth, open-ended interviews with 47 individuals (30 women, 17 men living with HIV/AIDS recruited from AIDS treatment programs in Mbarara and Kampala, Uganda to understand how food insecurity interferes with ARV therapy regimens. Interviews were transcribed, coded for key themes, and analyzed using grounded theory. FINDINGS: Food insecurity was common and an important barrier to accessing medical care and ARV adherence. Five mechanisms emerged for how food insecurity can contribute to ARV non-adherence and treatment interruptions or to postponing ARV initiation: 1 ARVs increased appetite and led to intolerable hunger in the absence of food; 2 Side effects of ARVs were exacerbated in the absence of food; 3 Participants believed they should skip doses or not start on ARVs at all if they could not afford the added nutritional burden; 4 Competing demands between costs of food and medical expenses led people either to default from treatment, or to give up food and wages to get medications; 5 While working for food for long days in the fields, participants sometimes forgot medication doses. Despite these obstacles, many participants still reported high ARV adherence and exceptional motivation to continue therapy. CONCLUSIONS: While reports from sub-Saharan Africa show excellent adherence to ARVs, concerns remain that these successes are not sustainable in the presence of widespread poverty and food insecurity. We provide further evidence on how food insecurity can compromise sustained ARV therapy in a resource-limited setting. Addressing food insecurity as part of emerging ARV treatment programs is critical for their long-term success.

    Background. Human immunodeficiency virus (HIV)-associated neurocognitive disorders (HAND) can show variable clinical trajectories. Previous longitudinal studies of HAND typically have been brief, did not use adequate normative standards, or were conducted in the context of a clinical trial, thereby limiting our understanding of incident neurocognitive (NC) decline and recovery. Methods. We investigated the incidence and predictors of NC change over 16–72 (mean, 35) months in 436 HIV-infected participants in the CNS HIV Anti-Retroviral Therapy Effects Research cohort. Comprehensive laboratory, neuromedical, and NC assessments were obtained every 6 months. Published, regression-based norms for NC change were used to generate overall change status (decline vs stable vs improved) at each study visit. Survival analysis was used to examine the predictors of time to NC change. Results. Ninety-nine participants (22.7%) declined, 265 (60.8%) remained stable, and 72 (16.5%) improved. In multivariable analyses, predictors of NC improvements or declines included time-dependent treatment status and indicators of disease severity (current hematocrit, albumin, total protein, aspartate aminotransferase), and baseline demographics and estimated premorbid intelligence quotient, non-HIV-related comorbidities, current depressive symptoms, and lifetime psychiatric diagnoses (overall model P < .0001). Conclusions. NC change is common in HIV infection and appears to be driven by a complex set of risk factors involving HIV disease, its treatment, and comorbid conditions. PMID:25362201

    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.

    Full Text Available Introduction Antiretroviral therapy (ART has been used to treat large numbers of patients living with human immunodeficiency virus (HIV infection. Lipid disorders are often observed in these patients, and include elevations in total cholesterol (TC and triglycerides (TG. Methods A cross-sectional study was performed using 333 patient records from the Regional Hospital of São José Doutor Homero de Miranda Gomes (HRSJHMG. The study population consisted of patients with HIV who were under medical follow up, either on or off drug treatment. The data were entered into Excel and exported to SPSS 16.0 for analysis using chi-square testing. We used prevalence ratios as the measure of association. Results Lipid abnormalities were observed in 78.9% of individuals who received ART. Of the 308 subjects on ART, 59.1%, 41.9%, and 33.1% had TG, TC and low-density lipoprotein (LDL abnormalities, respectively. The prevalence of LDL changes was 2.57-fold higher in individuals who had been using ART for more than 12 months, compared to those using ART for 6 to 12 months. Conclusions HIV patients showed a significant increase in the association between TC and TG levels and the use of ART. In particular, changes in TC, LDL and TG were greater in individuals who had received ART for over more than 12 months.

    Antiretroviral therapy (ART) has the potential to change processes of HIV stigmatisation. In this article, changing processes of stigmatisation among a group of people living with HIV (PLWH) on ART in Wakiso District, Uganda, are analysed using qualitative data from a study of PLWH's self-management of HIV on ART. There were 38 respondents (20 women, 18 men) who had been taking ART for at least 1 year. They were purposefully selected from government and non-government ART providers. Two in-depth interviews were held with each participant. Processes of reduced self-stigmatisation were clearly evident, caused by the recovery of their physical appearance and support from health workers. However most participants continued to conceal their status because they anticipated stigma; for example, they feared gossip, rejection and their status being used against them. Anticipated stigma was gendered: women expressed greater fear of enacted forms of stigma such as rejection by their partner; in contrast men's fears focused on gossip, loss of dignity and self-stigmatisation. The evidence indicates that ART has not reduced underlying structural drivers of stigmatisation, notably gender identities and inequalities, and that interventions are still required to mitigate and tackle stigmatisation, such as counselling, peer-led education and support groups that can help PLWH reconstruct alternative and more positive identities.

    Full Text Available BACKGROUND: Nonadherence to antiretroviral therapy (ARVT is an important behavioral determinant of the success of ARVT. Nonadherence may lead to virological failure, and increases the risk of development of drug resistance. Understanding the prevalence of nonadherence and associated factors is important to inform secondary HIV prevention efforts. METHODOLOGY/PRINCIPAL FINDINGS: We used data from a cross-sectional interview study of persons with HIV conducted in 18 U.S. states from 2000-2004. We calculated the proportion of nonadherent respondents (took or=4 medications; living in a shelter or on the street; and feeling "blue" >or=14 of the past 30 days. We found weaker associations with having both male-male sex and injection drug use risks for HIV acquisition; being prescribed ARVT for >or=21 months; and being prescribed a protease inhibitor (PI-based regimen not boosted with ritonavir. The median proportion of doses missed was 50%. The most common reasons for missing doses were forgetting and side effects. CONCLUSIONS/SIGNIFICANCE: Self-reported recent nonadherence was high in our study. Our data support increased emphasis on adherence in clinical settings, and additional research on how providers and patients can overcome barriers to adherence.

    Negative attitudes toward HIV medications may restrict utilization of antiretroviral therapy (ART) in Indonesian prisons where many people living with HIV (PLH) are diagnosed and first offered ART. This mixed-method study examines the influence of medication attitudes on ART utilization among HIV-infected Indonesian prisoners. Randomly-selected HIV-infected male prisoners (n = 102) completed face-to-face in-depth interviews and structured surveys assessing ART attitudes. Results show that although half of participants utilized ART, a quarter of those meeting ART eligibility guidelines did not. Participants not utilizing ART endorsed greater concerns about ART efficacy, safety, and adverse effects, and more certainty that ART should be deferred in PLH who feel healthy. In multivariate analyses, ART utilization was independently associated with more positive ART attitudes (AOR = 1.09, 95 % CI 1.03-1.16, p = 0.002) and higher internalized HIV stigma (AOR = 1.03, 95 % CI 1.00-1.07, p = 0.016). Social marketing of ART is needed to counteract negative ART attitudes that limit ART utilization among Indonesian prisoners. PMID:26400080

    Full Text Available Background. Nevirapine- (NVP- based antiretroviral therapy (ART and artesunate-amodiaquine are frequently coprescribed in areas of HIV and malaria endemicity. We explored the impact of this practice on artesunate and dihydroartemisinin pharmacokinetics. Methods. We conducted a parallel-group pharmacokinetic comparison between HIV-infected patients receiving NVP-based ART (n=10 and ART-naive controls (n=11. Artesunate-amodiaquine 200/600 mg was given daily for three days. Measurement of drug concentrations occurred between 0 and 96 hours after the final dose. Pharmacokinetic parameters were determined using noncompartmental analysis. Results. Comparing the NVP group to controls, clearance of artesunate was reduced 50% (1950 versus 2995 L/h; P=0.03, resulting in a 45% increase in the AUC0-96 (105 versus 69 ug∗hr/L; P=0.02. The half-life of dihydroartemisinin was shorter in the NVP group (1.6 versuss 3.2 h; P=0.004, but other dihydroartemisinin pharmacokinetic parameters were unchanged. A lower conversion of artesunate to dihydroartemisinin was observed in the NVP group (dihydroartemisinin: artesunate AUC0-96=5.6 versuss 8.5 in NVP and control groups, respectively, P=0.008. Conclusion. Although NVP-containing ART impacted some pharmacokinetic parameters of artesunate and dihydroartemisinin, overall exposure was similar or better in the NVP group.

    More than 3 million people were receiving antiretroviral therapy (ART) at the end of 2007, but this number represents only 31% of people clinically eligible for ART in resource-limited settings. The primary objective of this study is to summarize the key obstacles that impede the goal of universal access prevention, care, and treatment. We performed a systematic literature search to review studies that reported barriers to diagnosis and access to treatment of HIV/AIDS in resource-limited countries. Persons living with HIV/ AIDS commonly face economic, sociocultural, and behavioral obstacles to access treatment and care for HIV. A variety of programs to overcome these barriers have been implemented, including efforts to destigmatize HIV/AIDS, enhance treatment literacy, provide income-generation skills, decentralize HIV services, promote gender equality, and adopt a multisectoral approach to optimize limited resources. An understanding of these obstacles and suggested methods to overcome them must be addressed by global policy makers before universal ART access can be achieved. PMID:19721103

    Full Text Available Unprecedented efforts in the fields of biology, pharmacology and clinical care have contributed to progressively turn HIV infection from an inevitably fatal condition into a chronic manageable disease, at least in the countries where HIV infected people have full access to the potent antiretroviral drug combinations that allow a marked and sustained control of viral replication. However, since currently used treatments are unable to eradicate HIV from infected individuals, therapy must be lifelong, with the potential for short- and long-term, known and unknown, side effects, and high costs for health care systems. In addition, different patterns of unexpected systemic complications involving heart, bone, kidney and other organs are emerging. Although their pathogenesis is still under debate, they are likely to originate from chronic inflammation and immune dysfunction associated to HIV infection. A final consideration regards the dishomogenous pattern of HIV disease worldwide. In fact, access to HIV diagnosis, treatment and care are seriously limited in the geographical areas that are most affected, like Africa, which sustains 70% of the global burden of the infection. This is one of the greatest challenges that international institutions are asked to face today.

    Food insecurity and malnutrition negatively affect adherence to antiretroviral therapy (ART) and are associated with poor HIV clinical outcomes. We examined the effect of providing household food assistance and nutrition education on ART adherence. A 12-month prospective clinical trial compared the effect of a monthly household food basket (FB) plus nutrition education (NE) versus NE alone on ART adherence on 400 HIV patients at four clinics in Honduras. Participants had been receiving ART for an average of 3.7 years and were selected because they had suboptimal adherence. Primary outcome measures were missed clinic appointments, delayed prescription refills, and self-reported missed doses of ART. These three adherence measures improved for both groups over 12 months (p < 0.01), mostly within 6 months. On-time prescription refills improved for the FB plus NE group by 19.6 % more than the group receiving NE alone after 6 months (p < 0.01), with no further change at 12 months. Change in missed appointments and self-reported missed ART doses did not significantly differ by intervention group.

    In order to achieve optimal benefits of antiretroviral therapy (ART), caregivers of children receiving ART are required to attend routine clinic visits monthly and administer medication to the child as prescribed. Yet, the level of adherence to these behaviours varies considerably in many settings. As a way to achieve optimal adherence in rural KwaZulu-Natal, caregivers are required to attend routine counselling sessions at HIV treatment clinics that are centred on imparting information, motivation, and behavioural skills related to medication administration. According to the information-motivation-behavioural skills model, information related to adherence, motivation, and behavioural skills are necessary and fundamental determinants of adherence to ART. The purpose of the study was to observe and document the content of adherence counselling sessions that caregivers attending rural clinics in KwaZulu Natal receive. We observed 25 adherence counselling sessions, which lasted on average 8.1 minutes. Counselling typically consisted of counsellors recording patient attendance, reporting CD4 count and viral load results to caregivers, emphasising dose times, and asking caregivers to name their medications and dosage amounts. Patients were seldom asked to demonstrate how they measure the medication. They were also not probed for problems regarding treatment, even when an unsuppressed VL was reported to a caregiver. This paper calls attention to the sub-optimal level of counselling provided to patients on ART and the urgent need to standardise and improve the training, support, and debriefing provided to counsellors.

  19. World Health Organization guidelines should not change the CD4 count threshold for antiretroviral therapy initiation

    Directory of Open Access Journals (Sweden)

    Nathan Geffen

    2013-03-01

    Full Text Available The World Health Organization (WHO currently recommends that HIV-positive adults start antiretroviral therapy (ART at CD4 counts <350 cells/μl. Several countries have changed their guidelines to recommend ART irrespective of CD4 count or at a threshold of 500 CD4 cells/μl. Consequently, WHO is currently revising its treatment guidelines and considering recommending ART initiation at CD4 counts <500 cells/μl. Such decisions are critically important, as WHO guidelines inform healthcare policies in developing countries and are used by activists in their advocacy work. Changing the CD4 initiation point from 350 to 500 cells/μl would, however, be premature and have profound cost implications on Global Fund, President’s Emergency Plan for AIDS Relief (PEPFAR and developing country health budgets. We should be willing to campaign for such a change in guidelines despite cost implications, if supported by evidence. However, the evidence remains outstanding. S Afr J HIV Med 2013;14(1:6-7.

    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.

    Full Text Available Worldwide circulating HIV-1 genomes show extensive variation represented by different subtypes, polymorphisms and drug-resistant strains. Reports on the impact of sequence variation on antiretroviral therapy (ART outcomes are mixed. In this review, we summarize relevant published data from both resource-rich and resource-limited countries in the last 10 years on the impact of HIV-1 sequence diversity on treatment outcomes. The prevalence of transmission of drug resistant mutations (DRMs varies considerably, ranging from 0% to 27% worldwide. Factors such as geographic location, access and availability to ART, duration since inception of treatment programs, quality of care, risk-taking behaviors, mode of transmission, and viral subtype all dictate the prevalence in a particular geographical region. Although HIV-1 subtype may not be a good predictor of treatment outcome, review of emerging evidence supports the fact that HIV-1 genome sequence-resulting from natural polymorphisms or drug-associated mutations-matters when it comes to treatment outcomes. Therefore, continued surveillance of drug resistant variants in both treatment-naïve and treatment-experienced populations is needed to reduce the transmission of DRMs and to optimize the efficacy of the current ART armamentarium.

    Full Text Available Abstract Objective To evaluate the feasibility of a large immediate versus deferred antiretroviral therapy (ART study in children. Methods We conducted an open-label pilot randomized clinical trial study in 43 Thai children with CD4 15 to 24% of starting generic AZT/3TC/NVP immediately (Arm 1 or deferring until CD4 Results Recruitment took 15 months. Twenty-six of 69 (37.7% were not eligible due mainly to low CD4%. Twenty four and 19 were randomized to arms 1 and 2 respectively. All accepted the randomized arm; however, 3 in arm 1 stopped ART and 1 in arm 2 refused to start ART. Ten/19 (53% in arm 2 started ART. At baseline, median age was 4.8 yrs, CDC A:B were 36:7, median CD4 was 19% and viral load was 4.8 log. All in arm 1 and 17/19 in arm 2 completed the study (median of 134 weeks. No one had AIDS or death. Four in immediate arm had tuberculosis. Once started on ART, deferred arm children achieved similar CD4 and viral load response as the immediate arm. Adverse events were similar between arms. The deferred arm had a 26% ART saving. Conclusion Almost 40% of children were not eligible due mainly to low CD4% but adherence to randomized treatment and retention in trial were excellent. A larger study to evaluate when to start ART is feasible.

    Health behaviors such as retention in HIV medical care and adherence to antiretroviral therapy (ART) pose major challenges to reducing new HIV infections, addressing health disparities, and improving health outcomes. Andersen's Behavioral Model of Health Service Use provides a conceptual framework for understanding how patient and environmental factors affect health behaviors and outcomes, which can inform the design of intervention strategies. Factors affecting retention and adherence among persons with HIV include patient predisposing factors (e.g., mental illness, substance abuse), patient-enabling factors (e.g., social support, reminder strategies, medication characteristics, transportation, housing, insurance), and healthcare environment factors (e.g., pharmacy services, clinic experiences, provider characteristics). Evidence-based recommendations for improving retention and adherence include (1) systematic monitoring of clinic attendance and ART adherence; (2) use of peer or paraprofessional navigators to re-engage patients in care and help them remain in care; (3) optimization of ART regimens and pharmaceutical supply chain management systems; (4) provision of reminder devices and tools; (5) general education and counseling; (6) engagement of peer, family, and community support groups; (7) case management; and (8) targeting patients with substance abuse and mental illness. Further research is needed on effective monitoring strategies and interventions that focus on improving retention and adherence, with specific attention to the healthcare environment. PMID:25792300

    Full Text Available BACKGROUND: The Study of Aldesleukin with and without antiretroviral therapy (STALWART evaluated whether intermittent interleukin-2 (IL-2 alone or with antiretroviral therapy (ART around IL-2 cycles increased CD4(+ counts compared to no therapy. METHODOLOGY: Participants not on continuous ART with > or = 300 CD4(+ cells/mm(3 were randomized to: no treatment; IL-2 for 5 consecutive days every 8 weeks for 3 cycles; or the same IL-2 regimen with 10 days of ART administered around each IL-2 cycle. CD4(+ counts, HIV RNA, and HIV progression events were collected monthly. PRINCIPAL FINDINGS: A total of 267 participants were randomized. At week 32, the mean CD4(+ count was 134 cells greater in the IL-2 alone group (p<0.001, and 133 cells greater in the IL-2 plus ART group (p<0.001 compared to the no therapy group. Twelve participants in the IL-2 groups compared to 1 participant in the group assigned to no therapy experienced an opportunistic event or died (HR 5.84, CI: 0.59 to 43.57; p = 0.009. CONCLUSIONS: IL-2 alone or with peri-cycle HAART increases CD4(+ counts but was associated with a greater number of opportunistic events or deaths compared to no therapy. These results call into question the immunoprotective significance of IL-2-induced CD4(+ cells. TRIAL REGISTRATION: ClinicalTrials.gov NCT00110812.

    Full Text Available Objective: To describe the degree of HIV disease progression in infants initiating antiretroviral therapy (ART by three months of age in a programmatic setting in South Africa. Design: This was a programmatic cohort study. Methods: Electronic and manual data extraction from databases and antiretroviral registers in 20 public clinics in Cape Town and electronic data extraction from a large ART service at Chris Hani Baragwanath Hospital in Soweto were performed. Records of all infants initiated on ART by three months of age between June 2007 and September 2010 were extracted. Demographics, immunological and clinical stage at ART initiation were analyzed descriptively by chi-square, two-sample t-test and Kaplan–Meier methods. Results: A total of 403 records were identified: 88 in Cape Town and 315 in Soweto. Median age at ART initiation was 8.4 [interquartile range (IQR: 7.2–9.7] weeks. At ART initiation, 250 infants (62% had advanced HIV disease (CD4% <25% or absolute CD4<1500 cells/mm3 or WHO clinical Stage 3 or 4. Median age at ART initiation by site was 10.3 (IQR: 8.2–11.9 weeks in Cape Town and 8.6 (IQR: 7.7–10.0 weeks in Soweto infants (p<0.0001. In Cape Town, 73 infants (83% had advanced HIV disease at ART initiation, compared to 177 infants (56% in Soweto (p<0.0001. On logistic regression, each month increase in age at ART initiation lowered the odds of initiating ART in an optimal state (OR: 0.56, CI: 0.36–0.94 and increased the odds of advanced HIV disease at ART initiation (OR: 1.69, CI: 1.05–2.71. Conclusions: ART initiation by three months of age may not adequately prevent disease progression. New emphasis on early diagnosis and rapid initiation of ART in the first weeks of life are essential to further reduce infant mortality.

    Full Text Available Introduction: In response to the increasing burden of HIV, the Ugandan government has employed different service delivery models since 2004 that aim to reduce costs and remove barriers to accessing HIV care. These models include community-based approaches to delivering antiretroviral therapy (ART and delegating tasks to lower-level health workers. This study aimed to provide data on annual ART cost per client among three different service delivery models in Uganda. Methods: Costing data for the entire year 2012 were retrospectively collected as part of a larger task-shifting study conducted in three organizations in Uganda: Kitovu Mobile (KM, the AIDS Support Organisation (TASO and Uganda Cares (UC. A standard cost data capture tool was developed and used to retrospectively collect cost information regarding antiretroviral (ARV drugs and non-ARV drugs, ART-related lab tests, personnel and administrative costs. A random sample of four TASO centres (out of 11, four UC clinics (out of 29 and all KM outreach units were selected for the study. Results: Cost varied across sites within each organization as well as across the three organizations. In addition, the number of annual ART visits was more frequent in rural areas and through KM (the community distribution model, which played a major part in the overall annual ART cost. The annual cost per client (in USD was $404 for KM, $332 for TASO and $257 for UC. These estimates were lower than previous analyses in Uganda or the region compared to data from 2001 to 2009, but comparable with recent estimates using data from 2010 to 2013. ARVs accounted for the majority of the total cost, followed by personnel and operational costs. Conclusions: The study provides updated data on annual cost per ART visit for three service delivery models in Uganda. These data will be vital for in-country budgetary efforts to ensure that universal access to ART, as called for in the 2015 World Health Organization (WHO

    2010-05-01

    Full Text Available Abstract Increasing numbers of human immunodeficiency virus (HIV-infected women are now accessing life-prolonging highly active antiretroviral therapy (HAART in developing countries. There is a need for better understanding of interactions of human papillomavirus (HPV and HIV, especially in the context of increasing life expectancy due to HAART. The data regarding the impact of HAART on reducing the incidence and progression and facilitating the regression of HPV infection and cervical abnormalities is largely inconsistent. Published studies differ in their study designs (prospective or retrospective cohorts or record linkage studies, screening and diagnostic protocols, duration and type of HAART use, recruitment and referral strategies, and definitions of screening test and disease positivity. Due to the ethical and resource limitations in conducting randomized trials of the impact of HAART on incidence of HPV, CIN, and cervical cancer among HIV-infected women, it is important to consider innovative study designs, including quasi-experimental trials and operations research in sentinel populations to answer the critical research questions in this area.

    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

    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.

    Objective To identify factors associated with antiretroviral therapy (ART) attrition among patients initiating therapy in 2005–2011 at two large, public-sector department-level hospitals, and to inform interventions to improve ART retention. Methods This retrospective cohort study used data from the iSanté electronic medical record (EMR) system. The study characterized ART attrition levels and explored the patient demographic, clinical, temporal, and service utilization factors associated with ART attrition, using time-to-event analysis methods. Results Among the 2 023 patients in the study, ART attrition on average was 17.0 per 100 person-years (95% confidence interval (CI): 15.8–18.3). In adjusted analyses, risk of ART attrition was up to 89% higher for patients living in distant communes compared to patients living in the same commune as the hospital (hazard ratio: 1.89, 95%CI: 1.54–2.33; P < 0.001). Hospital site, earlier year of ART start, spending less time enrolled in HIV care prior to ART initiation, receiving a non-standard ART regimen, lacking counseling prior to ART initiation, and having a higher body mass index were also associated with attrition risk. Conclusions The findings suggest quality improvement interventions at the two hospitals, including: enhanced retention support and transportation subsidies for patients accessing care from remote areas; counseling for all patients prior to ART initiation; timely outreach to patients who miss ART pick-ups; “bridging services” for patients transferring care to alternative facilities; routine screening for anticipated interruptions in future ART pick-ups; and medical case review for patients placed on non-standard ART regimens. The findings are also relevant for policymaking on decentralization of ART services in Haiti. PMID:25563149

    Directly observed therapy (DOT) of antiretroviral (ARV) medications has beneficial effects on HIV treatment for incarcerated inmates but has been associated with limited continuation after release and inadvertent disclosure of HIV status. Guided self-administered therapy (g-SAT) may be a preferred method of ARV delivery and may encourage medication-taking behavior. We surveyed the preference of 102 HIV-positive jailed inmates at the San Francisco City and County Jails regarding receiving ARVs via DOT versus g-SAT while incarcerated. Participants overwhelmingly preferred g-SAT over DOT. PMID:22547327

    Full Text Available For full HIV virological suppression, three fully active antiretroviral agents are required. New drug classes should be included to ensure that agents are fully active. The addition of enfuvirtide and efavirenz to the present patient’s new antiretroviral regimen ensured that two fully active agents were in use in the setting of a moderate degree of nucleoside resistance and a high level of protease resistance, and where non-nucleoside reverse transcriptase inhibitors were still fully active. Both viral load and CD4 count responded favourably to this regimen. The patient received support from physicians and clinic staff in the introduction and use of enfuvirtide. To reduce injection site reactions, a needle-free injection system (Biojector proved effective.

    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.

  15. HIV-1 transmission during early antiretroviral therapy: evaluation of two HIV-1 transmission events in the HPTN 052 prevention study.

    Li-Hua Ping

    Full Text Available In the HPTN 052 study, transmission between HIV-discordant couples was reduced by 96% when the HIV-infected partner received suppressive antiretroviral therapy (ART. We examined two transmission events where the newly infected partner was diagnosed after the HIV-infected partner (index initiated therapy. We evaluated the sequence complexity of the viral populations and antibody reactivity in the newly infected partner to estimate the dates of transmission to the newly infected partners. In both cases, transmission most likely occurred significantly before HIV-1 diagnosis of the newly infected partner, and either just before the initiation of therapy or before viral replication was adequately suppressed by therapy of the index. This study further strengthens the conclusion about the efficacy of blocking transmission by treating the infected partner of discordant couples. However, this study does not rule out the potential for HIV-1 transmission to occur shortly after initiation of ART, and this should be recognized when antiretroviral therapy is used for HIV-1 prevention.

    BACKGROUND: We described reasons for switching to second-line antiretroviral treatment (ART) and time to switch in HIV-infected children failing first-line ART in West Africa. METHODS: We included all children aged 15 years or less, starting ART (at least three drugs) in the paediatric IeDEA clin...... rare and switches after an immunological failure were insufficient. These gaps reveal that it is crucial to advocate for both sustainable access to first-line and alternative regimens to provide adequate roll-out of paediatric ART programmes....

    Full Text Available INTRODUCTION: HIV-infected children and adolescents treated with highly active antiretroviral therapy (HAART regimens that include a protease inhibitor (PI can show significant improvements in clinical outcomes, nutritional status and quality of life. The study aimed to report nutritional and metabolic alterations for pediatric patients continuously exposed to HAART and for healthy controls for up to 1 year. METHODS: Clinical, anthropometric, lipid profile and food intake data were collected prospectively over approximately 12-months for each patient. RESULTS: Fifty-one individuals were studied, of these, 16 were healthy. After 12 months follow-up, HIV-positive individuals remained below the healthy control group parameters. No change was observed concerning food intake. Triglyceride serum levels were higher in patients using protease inhibitor at the onset of the study [PI groups: 114 (43 - 336, and 136 (63 - 271 versus control group: 54.5 (20 - 162; p = 0.003], but after twelve months follow-up, only the group using protease inhibitor for up to two months presented higher values [140 (73 - 273 versus 67.5 (33 - 117; p = 0.004]. HDL-cholesterol was lower in HIV-positive individuals [HIV-positive groups: 36 (27 - 58 and 36 (23 - 43; control 49.5 (34 - 69; p = 0.004]. CONCLUSIONS: HIV-infected children and adolescents treated with highly active antiretroviral therapy showed compromised nutritional parameters compared to a paired healthy control group. Individuals using protease inhibitor presented worse triglyceride serum levels compared to their healthy counterparts.INTRODUÇÃO: Crianças e adolescentes infectadas pelo HIV e tratadas com terapia antirretroviral de alta potência (TAAP, que inclui inibidor de protease (IP podem apresentar significante melhora clínica no estado nutricional e na qualidade de vida.

    Full Text Available Background. With the increase in scaling up of antiretroviral therapy (ART, knowledge of the need for adherence to ART is pivotal for successful treatment outcomes. Design and Methods. A cross-sectional study was carried out between October and December 2013. We administered theory of planned behaviour (TPB and adherence questionnaires to 358 women aged 18-49 years, from a rural and urban ART-clinics in southern Malawi. Hierarchical linear regression models were used to predict intentions to adhere to ART. Results. Regression models showed that attitude (β=0.47, subjective norm (β=0.31, and perceived behavioral control (β=0.12 explain 55% of the variance in intentions to adhere to ART. The relationship between both food insecurity and perceived side effects with intentions to adhere to ART is mediated by attitude, subjective norm, and perceived behavioural control. Household (r=0.20 and individual (r=0.21 food insecurity were positively and significantly correlated with perceived behavioural control. Household food insecurity had a negative correlation with perceived side effects (r=-0.11. Perceived side effects were positively correlated with attitude (r=0.25. There was no statistically significant relationship between intentions to adhere to ART in the future and one month self-report of past month adherence. These interactions suggest that attitude predicted adherence only when food insecurity is high or perception of side effects is strong.Conclusions. This study shows that modification might be needed when using TPB constructs in resource constraint environments

    Full Text Available Abstract Background As the resource implications of expanding anti-retroviral therapy (ART are likely to be large, there is a need to explore its cost-effectiveness. So far, there is no such information available from Ethiopia. Objective To assess the cost-effectiveness of ART for routine clinical practice in a district hospital setting in Ethiopia. Methods We estimated the unit cost of HIV-related care from the 2004/5 fiscal year expenditure of Arba Minch Hospital in southern Ethiopia. We estimated outpatient and inpatient service use from HIV-infected patients who received care and treatment at the hospital between January 2003 and March 2006. We measured the health effect as life years gained (LYG for patients receiving ART compared with those not receiving such treatment. The study adopted a health care provider perspective and included both direct and overhead costs. We used Markov model to estimate the lifetime costs, health benefits and cost-effectiveness of ART. Findings ART yielded an undiscounted 9.4 years expected survival, and resulted in 7.1 extra LYG compared to patients not receiving ART. The lifetime incremental cost is US$2,215 and the undiscounted incremental cost per LYG is US$314. When discounted at 3%, the additional LYG decreases to 5.5 years and the incremental cost per LYG increases to US$325. Conclusion The undiscounted and discounted incremental costs per LYG from introducing ART were less than the per capita GDP threshold at the base year. Thus, ART could be regarded as cost-effective in a district hospital setting in Ethiopia.

    Introduction This study aimed at estimating the incidence of pregnancy after antiretroviral therapy (ART) initiation in eight West African countries over a 10-year period. Methods A retrospective analysis was conducted within the international database of the IeDEA West Africa Collaboration. All HIV-infected women aged <50 years and starting ART for their own health between 1998 and 2011 were eligible. Pregnancy after ART initiation was the main outcome and was based on clinical reporting. Poisson regression analysis accounting for country heterogeneity was computed to estimate first pregnancy incidence post-ART and to identify its associated factors. Pregnancy incidence rate ratios were adjusted on country, baseline CD4 count and clinical stage, haemoglobin, age, first ART regimen and calendar year. Results Overall 29,425 HIV-infected women aged 33 years in median [Inter Quartile Range: 28–38] contributed for 84,870 women-years of follow-up to this analysis. The crude incidence of first pregnancy (2,304 events) was 2.9 per 100 women-years [95% confidence interval [CI]: 2.7–3.0], the highest rate being reported among women aged 25–29 years: 4.7 per 100 women-years; 95% CI: 4.3–5.1. The overall Kaplan-Meier probability of pregnancy occurrence by the fourth year on ART was 10.9% (95% CI: 10.4–11.4) and as high as 28.4% (95% CI: 26.3–30.6) among women aged 20–29 years at ART initiation. Conclusion The rate of pregnancy occurrence after ART initiation among HIV-infected women living in the West Africa region was high. Family planning services tailored to procreation needs should be provided to all HIV-infected women initiating ART and health consequences carefully monitored in this part of the world.

    Full Text Available OBJECTIVE: To evaluate the prevalence of and the associated factors for metabolic syndrome (MS among Latin American HIV-infected patients receiving antiretroviral therapy (ART using baseline data from the RAPID II study. METHODS: A longitudinal study to evaluate the metabolic profile, cardiovascular disease (CVD risk and associated treatment practices to reduce this risk has been conducted in seven Latin American countries (the RAPID II study. Adult HIV patients with at least six months of RT were enrolled. MS was defined following ATP-III criteria. Demographic and anthropometric data, serum biochemical and clinical parameters were compared in patients with and without MS using bivariate and multivariate analysis. RESULTS: A total of 4,010 patients were enrolled, 2,963 (74% were males. Mean age (SD was 41.9 (10.0 years. The prevalence of MS was 20.2%. Females had higher prevalence of MS than males (22.7% vs. 19.4%, p = 0.02. MS was driven by high triglycerides, low HDL-cholesterol and high blood pressure (HBP. Patients with MS had higher 10year CVD risk: 22.2% vs. 7.4%, p < 0.001. Age (OR: 1.05 per year, female gender (OR: 1.29, family history of CVD (OR: 1.28, CD4 cell count (OR: 1.09 per 100 cell increase, and protease inhibitor based-ART (OR: 1.33 correlated with MS in the multivariate analysis. CONCLUSIONS: Prevalence of MS in this setting was similar to that reported from developed countries. MS was driven by high triglycerides, low-HDL and HBP, and it was associated with higher risk of CVD. Traditional risk factors, female gender, immune reconstitution, and protease inhibitor based-ART correlated with MS.

    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.

    It has been shown that socioeconomic factors are associated with the prognosis of several chronic diseases; however, there is no recent systematic review of their effect on HIV treatment outcomes. We aimed to review the evidence regarding the existence of an association of socioeconomic status with virological and immunological response to antiretroviral therapy (ART). We systematically searched the current literature using the database PubMed. We identified and summarized original research studies in high-income countries that assessed the association between socioeconomic factors (education, employment, income/financial status, housing, health insurance, and neighbourhood-level socioeconomic factors) and virological response, immunological response, and ART nonadherence among people with HIV-prescribed ART. A total of 48 studies met the inclusion criteria (26 from the United States, six Canadian, 13 European, and one Australian), of which 14, six, and 35 analysed virological, immunological, and ART nonadherence outcomes, respectively. Ten (71%), four (67%), and 23 (66%) of these studies found a significant association between lower socioeconomic status and poorer response, and none found a significant association with improved response. Several studies showed that adjustment for nonadherence attenuated the association between socioeconomic status and ART response. Our review provides strong support that socioeconomic disadvantage is associated with poorer response to ART. However, most studies have been conducted in settings such as the United States without universal free healthcare access. Further study in settings with free access to ART could help assess the impact of socioeconomic status on ART outcomes and the mechanisms by which it operates. PMID:26919732

    Background: Among HIV-infected women, perinatal depression compromises clinical, maternal, and child health outcomes. Antiretroviral therapy (ART) is associated with lower depression symptom severity but the uniformity of effect through pregnancy and postpartum periods is unknown. Methods: We analyzed prospective data from 447 HIV-infected women (18–49 years) initiating ART in rural Uganda (2005–2012). Participants completed blood work and comprehensive questionnaires quarterly. Pregnancy status was assessed by self-report. Analysis time periods were defined as currently pregnant, postpartum (0–12 months post-pregnancy outcome), or non–pregnancy-related. Depression symptom severity was measured using a modified Hopkins Symptom Checklist 15, with scores ranging from 1 to 4. Probable depression was defined as >1.75. Linear regression with generalized estimating equations was used to compare mean depression scores over the 3 periods. Results: At enrollment, median age was 32 years (interquartile range: 27–37), median CD4 count was 160 cells per cubic millimeter (interquartile range: 95–245), and mean depression score was 1.75 (s = 0.58) (39% with probable depression). Over 4.1 median years of follow-up, 104 women experienced 151 pregnancies. Mean depression scores did not differ across the time periods (P = 0.75). Multivariable models yielded similar findings. Increasing time on ART, viral suppression, better physical health, and “never married” were independently associated with lower mean depression scores. Findings were consistent when assessing probable depression. Conclusions: Although the lack of association between depression and perinatal periods is reassuring, high depression prevalence at treatment initiation and continued incidence across pregnancy and non–pregnancy-related periods of follow-up highlight the critical need for mental health services for HIV-infected women to optimize both maternal and perinatal health.

    Our objective was to determine tuberculosis (TB) incidence and evaluate TB risk in adults after one or more years of use of combination antiretroviral therapy (cART) through a retrospective cohort study in Jos, Nigeria. We studied a cohort of HIV-infected adults treated with ART for at least 1 year. Based on immunologic and virologic responses to ART, patients were categorized into four groups: CD4 T cell count ≥350 cells/mm(3) and HIV-1 RNA level ≤400 copies/ml (group 1), CD4 T cell count ≥350 cells/mm(3) and HIV-1 RNA level >400 copies/ml (group 2), CD4 T cell count 400 copies/ml (group 4). Time to incident TB for the four groups was analyzed using the Kaplan-Meier method. Cox regression models were used to evaluate predictors of incident TB. In this cohort of 5,093 HIV-infected adults, of which 68.4% were female, with a mean age 35.1 years (standard deviation 9.1 years), we observed 98 cases of incident TB during 4 years and 3 months of follow-up. The overall TB incidence rate was 8.7 cases/1,000 patient-years of follow-up. Adjusted hazards for incident TB were 2.11 (95% CI 0.97-4.61), 2.05 (95% CI 1.10-3.79), and 3.65 (95% CI 1.15-5.06) in group 2, 3, and 4 patients, respectively, compared to group 1. Tuberculosis incidence in patients on ART is driven by poor immunologic and/or virologic response. Optimization of HIV treatment should be prioritized to reduce the burden of TB in this high-risk population.

    Full Text Available Abstract Background Highly selective antiretroviral (ARV regimens such as single dose nevirapine (NVP used for prevention of mother to child transmission (PMTCT in resource-limited settings produce transient increases in otherwise marginal subpopulations of cells infected by mutant genomes. The longer term implications for accumulation of further resistance mutations are not fully understood. Methods We develop a new strain-differentiated hybrid deterministic-stochastic population dynamic type model of healthy and infected cells. We explore how the transient increase in a population of cells transcribed with a common mutation (modelled deterministically, which occurs in response to a short course of monotherapy, has an impact on the risk of appearance of rarer, higher-order, therapy-defeating mutations (modelled stochastically. Results Scenarios with a transient of a magnitude and duration such as is known to occur under NVP monotherapy exhibit significantly accelerated viral evolution compared to no-treatment scenarios. We identify a possibly important new biological timescale; namely, the duration of persistence, after a seminal mutation, of a sub-population of cells bearing the new mutant gene, and we show how increased persistence leads to an increased probability that a rare mutant will be present at the moment at which a new treatment regimen is initiated. Conclusion Even transient increases in subpopulations of common mutants are associated with accelerated appearance of further rarer mutations. Experimental data on the persistence of small subpopulations of rare mutants, in unfavourable environments, should be sought, as this affects the risk of subverting later regimens.

  7. Trends and Determinants of Antiretroviral Therapy Patient Monitoring Practices in Kenya and Uganda.

    Emily Dansereau

    Full Text Available Patients receiving antiretroviral therapy (ART require routine monitoring to track response to treatment and assess for treatment failure. This study aims to identify gaps in monitoring practices in Kenya and Uganda.We conducted a systematic retrospective chart review of adults who initiated ART between 2007 and 2012. We assessed the availability of baseline measurements (CD4 count, weight, and WHO stage and ongoing CD4 and weight monitoring according to national guidelines in place at the time. Mixed-effects logistic regression models were used to analyze facility and patient factors associated with meeting monitoring guidelines.From 2007 to 2012, at least 88% of patients per year in Uganda had a recorded weight at initiation, while in Kenya there was a notable increase from 69% to 90%. Patients with a documented baseline CD4 count increased from 69% to about 80% in both countries. In 2012, 83% and 86% of established patients received the recommended quarterly weight monitoring in Kenya and Uganda, respectively, while semiannual CD4 monitoring was less common (49% in Kenya and 38% in Uganda. Initiating at a more advanced WHO stage was associated with a lower odds of baseline CD4 testing. On-site CD4 analysis capacity was associated with increased odds of CD4 testing at baseline and in the future.Substantial gaps were noted in ongoing CD4 monitoring of patients on ART. Although guidelines have since changed, limited laboratory capacity is likely to remain a significant issue in monitoring patients on ART, with important implications for ensuring quality care.

    The objective of this study was to describe the pregnancy intentions of pregnant HIV-infected Malawian women on antiretroviral therapy (ART) for at least 6 months prior to the current pregnancy, and to assess whether time on ART was associated with pregnancy intention. We conducted a cross-sectional analysis of HIV-infected Malawian women receiving antenatal care at a government hospital with a survey assessing ART history, reproductive history, and family planning use at conception. We used Pearson's chi-square tests and Fisher's exact tests to compare these parameters between women on ART greater than 24 months with those on ART less than 24 months. Modified Poisson regression was performed to assess the association between time on ART and pregnancy intention. Most women (75%) reported that their current pregnancy was unintended, defined as either Mistimed (21%) or Unwanted (79%). Women on ART for longer than 2 years were more likely to report an unintended pregnancy (79% versus 65%, p = .03), though there was no significant association between time on ART and pregnancy intention in multivariate analysis. Most women (79%) were using contraception at the time of conception, with condoms being most popular (91%), followed by injectables (9%) and the implant (9%). HIV-infected women on ART continue to experience high rates of unintended pregnancy in the Option B+ era. As Option B+ continues to be implemented in Malawi and increasing numbers of HIV-infected women initiate lifelong ART, ensuring that the most effective forms of contraception are accessible is necessary to decrease unintended pregnancy.

    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.

    Full Text Available BACKGROUND: Recent studies suggest certain antiretroviral therapy (ART drugs are associated with increases in cardiovascular disease. PURPOSE: We performed a systematic review and meta-analysis to summarize the available evidence, with the goal of elucidating whether specific ART drugs are associated with an increased risk of myocardial infarction (MI. DATA SOURCES: We searched Medline, Web of Science, the Cochrane Library, and abstract archives from the Conference on Retroviruses and Opportunistic Infections and International AIDS Society up to June 2011 to identify published articles and abstracts. STUDY SELECTION: Eligible studies were comparative and included MI, strokes, or other cardiovascular events as outcomes. DATA EXTRACTION: Eligibility screening, data extraction, and quality assessment were performed independently by two investigators. DATA SYNTHESIS: Random effects methods and Fisher's combined probability test were used to summarize evidence. FINDINGS: Twenty-seven studies met inclusion criteria, with 8 contributing to a formal meta-analysis. Findings based on two observational studies indicated an increase in risk of MI for patients recently exposed (usually defined as within last 6 months to abacavir (RR 1.92, 95% CI 1.51-2.42 and protease inhibitors (PI (RR 2.13, 95% CI 1.06-4.28. Our analysis also suggested an increased risk associated with each additional year of exposure to indinavir (RR 1.11, 95% CI 1.05-1.17 and lopinavir (RR 1.22, 95% CI 1.01-1.47. Our findings of increased cardiovascular risk from abacavir and PIs were in contrast to four published meta-analyses based on secondary analyses of randomized controlled trials, which found no increased risk from cardiovascular disease. CONCLUSION: Although observational studies implicated specific drugs, the evidence is mixed. Further, meta-analyses of randomized trials did not find increased risk from abacavir and PIs. Our findings that implicate specific ARTs in the

    Full Text Available Missing outcome data due to loss to follow-up occurs frequently in clinical cohort studies of HIV-infected patients. Censoring patients when they become lost can produce inaccurate results if the risk of the outcome among the censored patients differs from the risk of the outcome among patients remaining under observation. We examine whether patients who are considered lost to follow up are at increased risk of mortality compared to those who remain under observation. Patients from the US Centers for AIDS Research Network of Integrated Clinical Systems (CNICS who newly initiated combination antiretroviral therapy between January 1, 1998 and December 31, 2009 and survived for at least one year were included in the study. Mortality information was available for all participants regardless of continued observation in the CNICS. We compare mortality between patients retained in the cohort and those lost-to-clinic, as commonly defined by a 12-month gap in care. Patients who were considered lost-to-clinic had modestly elevated mortality compared to patients who remained under observation after 5 years (risk ratio (RR: 1.2; 95% CI: 0.9, 1.5. Results were similar after redefining loss-to-clinic as 6 months (RR: 1.0; 95% CI: 0.8, 1.3 or 18 months (RR: 1.2; 95% CI: 0.8, 1.6 without a documented clinic visit. The small increase in mortality associated with becoming lost to clinic suggests that these patients were not lost to care, rather they likely transitioned to care at a facility outside the study. The modestly higher mortality among patients who were lost-to-clinic implies that when we necessarily censor these patients in studies of time-varying exposures, we are likely to incur at most a modest selection bias.

  12. 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.

  13. Economic impact of HIV and antiretroviral therapy on education supply in high prevalence regions.

    Full Text Available BACKGROUND: We set out to estimate, for the three geographical regions with the highest HIV prevalence, (sub-Saharan Africa [SSA], the Caribbean and the Greater Mekong sub-region of East Asia, the human resource and economic impact of HIV on the supply of education from 2008 to 2015, the target date for the achievement of Education For All (EFA, contrasting the continuation of access to care, support and Antiretroviral therapy (ART to the scenario of universal access. METHODOLOGY/PRINCIPAL FINDINGS: A costed mathematical model of the impact of HIV and ART on teacher recruitment, mortality and absenteeism (Ed-SIDA was run using best available data for 58 countries, and results aggregated by region. It was estimated that (1 The impact of HIV on teacher supply is sufficient to derail efforts to achieve EFA in several countries and universal access can mitigate this. (2 In SSA, the 2008 costs to education of HIV were about half of those estimated in 2002. Providing universal access for teachers in SSA is cost-effective on education returns alone and provides a return of $3.99 on the dollar. (3 The impacts on education in the hyperendemic countries in Southern Africa will continue to increase to 2015 from its 2008 level, already the highest in the world. (4 If treatment roll-out is successful, numbers of HIV positive teachers are set to increase in all the regions studied. CONCLUSIONS/SIGNIFICANCE: The return on investing in care and support is also greater in those areas with highest impact. SSA requires increased investment in teacher support, testing and particularly ART if it is to achieve EFA. The situation for teachers in the Caribbean and East Asia is similar but on a smaller scale proportionate to the lower levels of infection and greater existing access to care and support.

    Studies from sub-Saharan Africa indicate that children made vulnerable by poverty have been disproportionately affected by HIV with many exposed via mother-to-child transmission. For youth living with HIV, adherence to life saving treatment regimens are likely to be affected by the complex set of economic and social circumstances that challenge their families and also exacerbate health problems. Using baseline data from the National Institute of Child and Human Development (NICHD) funded Suubi+Adherence study, we examined the extent to which individual and composite measures of equity predict self-reported adherence among Ugandan adolescents aged 10–16 (n = 702) living with HIV. Results showed that greater asset ownership, specifically familial possession of seven or more tangible assets, was associated with greater odds of self-reported adherence (OR 1.69, 95% CI: 1.00–2.85). Our analyses also indicated that distance to the nearest health clinic impacts youth’s adherence to an ARV regimen. Youth who reported living nearest to a clinic were significantly more likely to report optimal adherence (OR 1.49, 95% CI: 0.92–2.40). Moreover, applying the composite equity scores, we found that adolescents with greater economic advantage in ownership of household assets, financial savings, and caregiver employment had higher odds of adherence by a factor of 1.70 (95% CI: 1.07–2.70). These findings suggest that interventions addressing economic and social inequities may be beneficial to increase ART uptake among economically vulnerable youth, especially in sub-Saharan Africa. This is one of the first studies to address the question of equity in adherence to antiretroviral therapy among economically vulnerable youth with HIV. PMID:27392003

  16. What happens to patients on antiretroviral therapy who transfer out to another facility?

    Joseph Kwong-Leung Yu

    Full Text Available BACKGROUND: Long term retention of patients on antiretroviral therapy (ART in Africa's rapidly expanding programmes is said to be 60% at 2 years. Many reports from African ART programmes make little mention of patients who are transferred out to another facility, yet Malawi's national figures show a transfer out of 9%. There is no published information about what happens to patients who transfer-out, but this is important because if they transfer-in and stay alive in these other facilities then national retention figures will be better than previously reported. METHODOLOGY/PRINCIPAL FINDINGS: Of all patients started on ART over a three year period in Mzuzu Central Hospital, North Region, Malawi, those who transferred out were identified from the ART register and master cards. Clinic staff attempted to trace these patients to determine whether they had transferred in to a new ART facility and their outcome status. There were 805 patients (19% of the total cohort who transferred out, of whom 737 (92% were traced as having transferred in to a new ART facility, with a median time of 1.3 months between transferring-out and transferring-in. Survival probability was superior and deaths were lower in the transfer-out patients compared with those who did not transfer. CONCLUSION/SIGNIFICANCE: In Mzuzu Central Hospital, patients who transfer-out constitute a large proportion of patients not retained on ART at their original clinic of registration. Good documentation of transfer-outs and transfer-ins are needed to keep track of national outcomes. Furthermore, the current practice of regarding transfer-outs as being double counted in national cohorts and subtracting this number from the total national registrations to get the number of new patients started on ART is correct.

    The health of people living with HIV (PLWH) and the sustained success of antiretroviral therapy (ART) programmes depends on PLWH's motivation and ability to self-manage the condition over the long term, including adherence to drugs on a daily basis. PLWH's self-management of HIV and their wellbeing are likely to be interrelated. Successful self-management sustains wellbeing, and wellbeing is likely to motivate continued self-management. Detailed research is lacking on PLWH's self-management processes on ART in resource-limited settings. This paper presents findings from a study of PLWH's self-management and wellbeing in Wakiso District, Uganda. Thirty-eight PLWH (20 women, 18 men) were purposefully selected at ART facilities run by the government and by The AIDS Support Organisation in and around Entebbe. Two in-depth interviews were completed with each participant over three or four visits. Many were struggling economically, however the recovery of health and hope on ART had enhanced wellbeing and motivated self-management. The majority were managing their condition well across three broad domains of self-management. First, they had mobilised resources, notably through good relationships with health workers. Advice and counselling had helped them to reconceptualise their condition and situation more positively and see hope for the future, motivating their work to self-manage. Many had also developed a new network of support through contacts they had developed at the ART clinic. Second, they had acquired knowledge and skills to manage their health, a useful framework to manage their condition and to live their life. Third, participants were psychologically adjusting to their condition and their new 'self': they saw HIV as a normal disease, were coping with stigma and had regained self-esteem, and were finding meaning in life. Our study demonstrates the centrality of social relationships and other non-medical aspects of wellbeing for self-management which ART

    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

    Among people living with HIV (PLWH), adherence to antiretroviral therapy (ART) is crucial for health, but patients face numerous challenges achieving sustained lifetime adherence. We conducted six focus groups with 56 PLWH regarding ART adherence barriers and collected sociodemographics and ART histories. Participants were recruited through clinics and AIDS service organizations in North Carolina. Dedoose software was used to support thematic analysis. Participants were 59% male, 77% black, aged 23-67 years, and living with HIV 4-20 years. Discussions reflected the fluid, complex nature of ART adherence. Maintaining adherence required participants to indefinitely assert consistent control across multiple areas including: their HIV disease, their own bodies, health care providers, and social systems (e.g., criminal justice, hospitals, drug assistance programs). Participants described limited control over treatment options, ART's impact on their body, and inconsistent access to ART and subsequent inability to take ART as prescribed. When participants felt they had more decision-making power, intentionally choosing whether and how to take ART was not exclusively a decision about best treating HIV. Instead, through these decisions, participants tried to regain some amount of power and control in their lives. Supportive provider relationships assuaged these struggles, while perceived side-effects and multiple co-morbidities further complicated adherence. Adherence interventions need to better convey adherence as a continuous, changing process, not a fixed state. A perspective shift among care providers could also help address negative consequences of the perceived power struggles and pressures that may drive patients to exert control via intentional medication taking practices.

    Full Text Available Introduction: Every year, approximately 260,000 children are infected with HIV in low- and middle-income countries. The timely initiation and high level of maintenance of antiretroviral therapy (ART are crucial to reducing the suffering of HIV-positive children. We need to develop a better understanding of the background of children's ART non-adherence because it is not well understood. The purpose of this study is to explore the background related to ART non-adherence, specifically in relation to the orphan status of children in Kigali, Rwanda. Methods: We conducted 19 focus group discussions with a total of 121 caregivers of HIV-positive children in Kigali. The primary data for analysis were verbatim transcripts and socio-demographic data. A content analysis was performed for qualitative data analysis and interpretation. Results: The study found several contextual factors that influenced non-adherence: among double orphans, there was psychological distance between the caregivers and children, whereas economic burden was the primary issue among paternal orphans. The factors promoting adherence also were unique to each orphan status, such as the positive attitude about disclosing serostatus to the child by double orphans’ caregivers, and feelings of guilt about the child's condition among non-orphaned caregivers. Conclusions: Knowledge of orphan status is essential to elucidate the factors influencing ART adherence among HIV-positive children. In this qualitative study, we identified the orphan-related contextual factors that influenced ART adherence. Understanding the social context is important in dealing with the challenges to ART adherence among HIV-positive children.

    Background Lopinavir/ritonavir (LPV/r) is widely used in Cambodia with high efficacy but scarce data exist on long-term metabolic toxicity. Methods We carried out a cross-sectional and retrospective study evaluating metabolic disorders and cardiovascular risk in Cambodian patients on LPV/r-based antiretroviral therapy (ART) for > 1 year followed in Calmette Hospital, Phnom Penh. Data collected included cardiovascular risk factors, fasting blood lipids and glucose, and retrospective collection of bioclinical data. We estimated the 10-year risks of coronary heart disease with the Framingham, Ramathibodi-Electricity Generating Authority of Thailand (Rama-EGAT), and the Data Collection on Adverse Effects of Anti-HIV Drugs (D:A:D) risk equations. We identified patients with LDL above targets defined by the French expert group on HIV and by the HIV Medicine Association of the Infectious Disease Society of America and the Adult AIDS Clinical Trials Group (IDSA-AACTG). Results Of 115 patients enrolled—mean age 40.9 years, 69.2% male, mean time on LPV/r 3.8 years—40 (34.8%) had hypercholesterolemia (> 2.40 g/L), and 69 (60.0%) had low HDL cholesterol (< 0.40 g/L). Twelve (10.5%), 28 (24%) and 9 (7.7%) patients had a 10-year risk of coronary heart disease ≥ 10% according to the Framingham, D:A:D, and Rama-EGAT score, respectively. Fifty one (44.4%) and 36 (31.3%) patients had not reached their LDL target according to IDSA-AACTG and French recommendations, respectively. Conclusion Prevalence of dyslipidemia was high in this cohort of HIV-infected Cambodian patients on LPV/r. Roughly one third had high LDL levels requiring specific intervention. PMID:27579612

    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

    Objective To determine individual and dyadic factors associated with effective contraceptive use among HIV-infected women accessing antiretroviral therapy (ART) in rural Uganda. Study Design HIV-infected women enrolled in the Uganda AIDS Rural Treatment Outcomes cohort completed questionnaires (detailing socio-behavioral characteristics, sexual and reproductive history, contraceptive use, fertility desires), and phlebotomy (October 2011–March 2013). We describe prevalence of effective contraceptive use (i.e., consistent condom use, and/or oral contraceptives, injectable hormonal contraception, intrauterine device, female sterilization) in the previous six months among sexually active, non-pregnant women (18–40 years). We assessed covariates of contraceptive use using multivariable logistic regression. Results 362 women (median values: age 30 years, CD4 count 397 cells/mm3, 4.0 years since ART initiation) were included. Among 284 sexually active women, 50% did not desire a(nother) child and 51% had a sero-concordant partner. 45% (n=127) reported effective contraceptive use of whom, 57% (n=72) used condoms, 42% (n=53) injectables, 12% (n=15) oral contraceptives, and 11% (n=1
