• Kaposi's sarcoma in an HIV-positive person successfully treated with paclitaxel

      Dongre, Atul; Montaldo, Chiara (Medknow, 2009-05)
      Epidemic Kaposi's sarcoma is one of the malignant neoplasms, which can develop in HIV-infected patients. Although the prevalence of HIV infection is reported to be high in Asian countries, Kaposi's sarcoma is rarely reported. We report a case of Kaposi's sarcoma involving the skin and oral mucosa along with extensive bilateral lymphedema of lower extremities, treated successfully with paclitaxel and antiretrovirals.

      Bemelmans, Marielle; van der Akker, Thomas; Pasulani, Olesi; Saddiq Tayub, Nabila; Hermann, Katharina; Mwagomba, Beatrice; Jalasi, Winnie; Chiomba, Harriet; Ford, Nathan; Philips, Mit (2011-01-05)
      ABSTRACT: BACKGROUND: In Malawi, the dramatic shortage of human resources for health is negatively impacted by HIV-related morbidity and mortality among health workers and their relatives. Many staff find it difficult to access HIV care through regular channels due to fear of stigma and discrimination. In 2006, two workplace initiatives were implemented in Thyolo District: a clinic at the district hospital dedicated to all district health staff and their first-degree relatives, providing medical services, including HIV care; and a support group for HIV-positive staff. METHODS: Using routine programme data, we evaluated the following outcomes up to the end of 2009: uptake and outcomes of HIV testing and counselling among health staff and their dependents; uptake and outcomes of antiretroviral therapy (ART) among health staff; and membership and activities of the support group. In addition, we included information from staff interviews and a job satisfaction survey to describe health workers' opinions of the initiatives. RESULTS: Almost two-thirds (91 of 144, 63%) of health workers and their dependents undergoing HIV testing and counselling at the staff clinic tested HIV positive. Sixty-four health workers had accessed ART through the staff clinic, approximately the number of health workers estimated to be in need of ART. Of these, 60 had joined the support group. Cumulative ART outcomes were satisfactory, with more than 90% alive on treatment as of June 2009 (the end of the study observation period). The availability, confidentiality and quality of care in the staff clinic were considered adequate by beneficiaries. CONCLUSIONS: Staff clinic and support group services successfully provided care and support to HIV-positive health workers. Similar initiatives should be considered in other settings with a high HIV prevalence.
    • Knowledge, attitudes and behaviours towards people with HIV and AIDS among private higher education students in Johannesburg, South Africa

      Khamisa, N; Mokgobi, M; Basera, T (Health and Medical Publishing Group, 2020-03-24)
      Background Human immunodeficiency virus and acquired immunodeficiency syndrome (HIV and AIDS) is a global health and social problem, with South Africa having an estimated overall prevalence rate of 13.5%. Compared to young male participants, young female participants have been reported to have less knowledge about HIV and AIDS, including prevention strategies, and this is associated with risky sexual behaviours and negative attitudes towards condom use. Objectives The study investigated gender differences in knowledge, attitudes and behaviours towards HIV and AIDS among 542 private higher education students in Johannesburg, South Africa. Method Participants completed an online structured questionnaire measuring knowledge, attitudes and behaviours as well as demographics (including age, gender and relationship status). Results The results indicate that overall there were no significant differences between male and female students in terms of HIV and AIDS knowledge. However, female students had significantly less knowledge with regard to unprotected anal sex as a risk factor for HIV and AIDS. In addition, young female students reported condom use at last sex less frequently than male students. Nonetheless, both genders reported a positive attitude towards condom use and towards people living with HIV and AIDS. Conclusion It is recommended that the relevant authorities at the state and the higher education level seriously consider implementing specific strategies for preventing HIV and AIDS through improved knowledge, attitudes and behaviours among young females.
    • The kynurenine pathway of tryptophan catabolism, CD4+ T-cell recovery, and mortality among HIV-infected Ugandans initiating antiretroviral therapy.

      Byakwaga, Helen; Boum, Yap; Huang, Yong; Muzoora, Conrad; Kembabazi, Annet; Weiser, Sheri D; Bennett, John; Cao, Huyen; Haberer, Jessica E; Deeks, Steven G; et al. (Oxford University Press, 2014-08-01)
      Human immunodeficiency virus (HIV) infection-induced indoleamine 2,3-dioxygenase-1 (IDO) expression in activated monocytes and dendritic cells catabolizes tryptophan to kynurenine and other downstream catabolites that inhibit T-cell proliferation and interleukin 17 (IL-17) production. The prognostic significance of this pathway in treated HIV disease is unknown.
    • Lamivudine monotherapy as a holding regimen for HIV-positive children.

      Patten, G; Bernheimer, J; Fairlie, L; Rabie, H; Sawry, S; Technau, K; Eley, B; Davies, MA (Public Library of Science, 2018-10-11)
      BACKGROUND: In resource-limited settings holding regimens, such as lamivudine monotherapy (LM), are used to manage HIV-positive children failing combination antiretroviral therapy (cART) to mitigate the risk of drug resistance developing, whilst adherence barriers are addressed or when access to second- or third-line regimens is restricted. We aimed to investigate characteristics of children placed on LM and their outcomes. METHODS: We describe the characteristics of children (age <16 years at cART start) from 5 IeDEA-SA cohorts with a record of LM during their treatment history. Among those on LM for >90 days we describe their immunologic outcomes on LM and their immunologic and virologic outcomes after resuming cART. FINDINGS: We included 228 children in our study. At LM start their median age was 12.0 years (IQR 7.3-14.6), duration on cART was 3.6 years (IQR 2.0-5.9) and median CD4 count was 605.5 cells/μL (IQR 427-901). Whilst 110 (48%) had no prior protease inhibitor (PI)-exposure, of the 69 with recorded PI-exposure, 9 (13%) patients had documented resistance to all PIs. After 6 months on LM, 70% (94/135) experienced a drop in CD4, with a predicted average CD4 decline of 46.5 cells/μL (95% CI 37.7-55.4). Whilst on LM, 46% experienced a drop in CD4 to <500 cells/μL, 18 (8%) experienced WHO stage 3 or 4 events, and 3 children died. On resumption of cART the average gain in CD4 was 15.65 cells/uL per month and 66.6% (95% CI 59.3-73.7) achieved viral suppression (viral load <1000) at 6 months after resuming cART. INTERPRETATION: Most patients experienced immune decline on LM. Its use should be avoided in those with low CD4 counts, but restricted use may be necessary when treatment options are limited. Managing children with virologic failure will continue to be challenging until more treatment options and better adherence strategies are available.

    • The Last and First Frontier--Emerging Challenges for HIV Treatment and Prevention in the First week of Life With Emphasis on Premature and Low Birth Weight Infants

      Cotton, MF; Holgate, S; Nelson, A; Rabie, H; Wedderburn, C; Mirochnick, M (International AIDS Society, 2015-12-02)
      There is new emphasis on identifying and treating HIV in the first days of life and also an appreciation that low birth weight (LBW) and preterm delivery (PTD) frequently accompany HIV-related pregnancy. Even in the absence of HIV, PTD and LBW contribute substantially to neonatal and infant mortality. HIV-exposed and -infected infants with these characteristics have received little attention thus far. As HIV programs expand to meet the 90-90-90 target for ending the HIV pandemic, attention should focus on newborn infants, including those delivered preterm or of LBW.
    • Lessons learned during down referral of antiretroviral treatment in Tete, Mozambique.

      Decroo, T; Panunzi, I; das Dores, C; Maldonado, F; Biot, M; Ford, N; Chu, K; South African Medical Unit, Médecins Sans Frontières, Johannesburg, South Africa. kathyrn.chu@joburg.msf.org. (2009-05-06)
      ABSTRACT: As sub-Saharan African countries continue to scale up antiretroviral treatment, there has been an increasing emphasis on moving provision of services from hospital level to the primary health care clinic level. Delivery of antiretroviral treatment at the clinic level increases the number of entry points to care, while the greater proximity of services encourages retention in care.In Tete City, Mozambique, patients on antiretrovirals were rapidly down referred from a provincial hospital to four urban clinics in large numbers without careful planning, resulting in a number of patients being lost to follow-up.We outline some key lessons learned to support down referral, including the need to improve process management, clinic infrastructure, monitoring systems, and patient preparation. Down referral can be avoided by initiating patients' antiretroviral treatment at clinic level from the outset.
    • Lessons learned: Retrospective assessment of outcomes and management of patients with advanced HIV disease in a semi-urban polyclinic in Epworth, Zimbabwe.

      Blankley, S; Gashu, T; Ahmad, B; Belaye, AK; Ringtho, L; Mesic, A; Zizhou, S; Casas, EC (Public Library of Science, 2019-04-10)
      HIV continues to be one of the leading causes of infectious death worldwide and presentation with advanced HIV disease is associated with increased morbidity and mortality. Recommendations for the management of advanced HIV disease include prompt screening and treatment of opportunistic infections, rapid initiation of ART and intensified adherence support. We present treatment outcomes of a cohort of patients presenting with advanced HIV disease in a semi-urban Zimbabwean polyclinic. Retrospective cohort analysis of adult patients enrolled for care at Epworth polyclinic, Zimbabwe between 2007 and end June 2016. Treatment outcomes at 6 and 12 months were recorded. Multivariate logistical regression analysis was undertaken to identify risk factors for presentation with advanced HIV Disease (CD4 count less than 200 cells/mm3 or WHO stage 3 or 4) and risks for attrition at 12 months. 16,007 anti-retroviral therapy naive adult patients were included in the final analysis, 47.4% of whom presented with advanced HIV disease. Patients presenting with advanced HIV disease had a higher mortality rate at 12 months following enrollment compared to early stage patients (5.11% vs 0.45%). Introduction of a package of differentiated care for patients with a CD4 count of less than 100 cells/mm3 resulted in diagnosis of cryptococcal antigenaemia in 7% of patients and a significant increase in the diagnosis of TB, although there was no significant difference in attrition at 6 or 12 months for these patients compared to those enrolled prior to the introduction of the differentiated care. The burden of advanced HIV disease remained high over the study period in this semi-urban polyclinic in Zimbabwe. Introduction of a package of differentiated care for those with advanced HIV disease increased the diagnosis of opportunistic infections and represents a model of care which can be replicated in other polyclinics in the resource constrained Zimbabwean context.

    • Lived experiences of palliative care among people living with HIV/AIDS: a qualitative study from Bihar, India.

      Nair, M; Kumar, P; Mahajan, R; Harshana, A; Richardson, K; Moreto-Planas, L; Burza, S (BMJ Publishing Group, 2020-10-05)
      Objectives: This study aimed to assess the lived experiences of palliative care among critically unwell people living with HIV/AIDS (PLHA), caregivers and relatives of deceased patients. It also aimed to understand the broader palliative care context in Bihar. Design: This was an exploratory, qualitative study which used thematic analysis of semistructured, in-depth interviews as well as a focus group discussion. Setting: All interviews took place in a secondary care hospital in Patna, Bihar which provides holistic care to critically unwell PLHA. Participants: We purposively selected 29 participants: 10 critically unwell PLHA, 5 caregivers of hospitalised patients, 7 relatives of deceased patients who were treated in the secondary care hospital and 7 key informants from community-based organisations. Results: Critically ill PLHA emphasised the need for psychosocial counselling and opportunities for social interaction in the ward, as well as a preference for components of home-based palliative care, even though they were unfamiliar with actual terms such as 'palliative care' and 'end-of-life care'. Critically unwell PLHA generally expressed preference for separate, private inpatient areas for end-of-life care. Relatives of deceased patients stated that witnessing patients' deaths caused trauma for other PLHA. Caregivers and relatives of deceased patients felt there was inadequate time and space for grieving in the hospital. While both critically ill PLHA and relatives wished that poor prognosis be transparently disclosed to family members, many felt it should not be disclosed to the dying patients themselves. Conclusions: Despite expected high inpatient fatality rates, PLHA in Bihar lack access to palliative care services. PLHA receiving end-of-life care in hospitals should have a separate dedicated area, with adequate psychosocial counselling and activities to prevent social isolation. Healthcare providers should make concerted efforts to inquire, understand and adapt their messaging on prognosis and end-of-life care based on patients' preferences.

    • Long-term virologic responses to antiretroviral therapy among HIV-positive patients entering adherence clubs in Khayelitsha, Cape Town, South Africa: a longitudinal analysis

      Kehoe, K; Boulle, A; Tsondai, PR; Euvrard, J; Davies, MA; Cornell, M (Wiley, 2020-05-14)
      Introduction In South Africa, an estimated 4.6 million people were accessing antiretroviral therapy (ART) in 2018. As universal Test and Treat is implemented, these numbers will continue to increase. Given the need for lifelong care for millions of individuals, differentiated service delivery models for ART services such as adherence clubs (ACs) for stable patients are required. In this study, we describe long‐term virologic outcomes of patients who have ever entered ACs in Khayelitsha, Cape Town. Methods We included adult patients enrolled in ACs in Khayelitsha between January 2011 and December 2016 with a recorded viral load (VL) before enrolment. Risk factors for an elevated VL (VL >1000 copies/mL) and confirmed virologic failure (two consecutive VLs >1000 copies/mL one year apart) were estimated using Cox proportional hazards models. VL completeness over time was assessed. Results Overall, 8058 patients were included in the analysis, contributing 16,047 person‐years of follow‐up from AC entry (median follow‐up time 1.7 years, interquartile range [IQR]:0.9 to 2.9). At AC entry, 74% were female, 46% were aged between 35 and 44 years, and the median duration on ART was 4.8 years (IQR: 3.0 to 7.2). Among patients virologically suppressed at AC entry (n = 8058), 7136 (89%) had a subsequent VL test, of which 441 (6%) experienced an elevated VL (median time from AC entry 363 days, IQR: 170 to 728). Older age (adjusted hazard ratio [aHR] 0.64, 95% confidence interval [CI] 0.46 to 0.88), more recent year of AC entry (aHR 0.76, 95% CI 0.68 to 0.84) and higher CD4 count (aHR 0.67, 95% CI 0.54 to 0.84) were protective against experiencing an elevated VL. Among patients with an elevated VL, 52% (150/291) with a repeat VL test subsequently experienced confirmed virologic failure in a median time of 112 days (IQR: 56 to 168). Frequency of VL testing was constant over time (82 to 85%), with over 90% of patients remaining virologically suppressed. Conclusions This study demonstrates low prevalence of elevated VLs and confirmed virologic failure among patients who entered ACs. Although ACs were expanded rapidly, most patients were well monitored and remained stable, supporting the continued rollout of this model.
    • Loss of correlation between HIV viral load and CD4+ T-cell counts in HIV/HTLV-1 co-infection in treatment naive Mozambican patients

      Bhatt, N B; Gudo, E S; Semá, C; Bila, D; Di Mattei, P; Augusto, O; Garsia, R; Jani, I V; Department of Immunology, Instituto Nacional de Saúde, Maputo, Mozambique; HIV Outpatient Clinic, Alto Mae Health Centre, Medecins Sans Frontieres, Switzerland, Maputo, Mozambique; Department of Medicine, University of Sydney, New South Wales, Australia;Department of Clinical Immunology, Royal Prince Alfred Hospital, Camperdown, NSW, Australia (2009-12-01)
      Seven hundred and four HIV-1/2-positive, antiretroviral therapy (ART) naïve patients were screened for HTLV-1 infection. Antibodies to HTLV-1 were found in 32/704 (4.5%) of the patients. Each co-infected individual was matched with two HIV mono-infected patients according to World Health Organization clinical stage, age +/-5 years and gender. Key clinical and laboratory characteristics were compared between the two groups. Mono-infected and co-infected patients displayed similar clinical characteristics. However, co-infected patients had higher absolute CD4+ T-cell counts (P = 0.001), higher percentage CD4+ T-cell counts (P < 0.001) and higher CD4/CD8 ratios (P < 0.001). Although HIV plasma RNA viral loads were inversely correlated with CD4+ T-cell-counts in mono-infected patients (P < 0.0001), a correlation was not found in co-infected individuals (P = 0.11). Patients with untreated HIV and HTLV-1 co-infection show a dissociation between immunological and HIV virological markers. Current recommendations for initiating ART and chemoprophylaxis against opportunistic infections in resource-poor settings rely on more readily available CD4+ T-cell counts without viral load parameters. These guidelines are not appropriate for co-infected individuals in whom high CD4+ T-cell counts persist despite high HIV viral load states. Thus, for co-infected patients, even in resource-poor settings, HIV viral loads are likely to contribute information crucial for the appropriate timing of ART introduction.
    • Loss to follow up from isoniazid preventive therapy among adults attending HIV voluntary counseling and testing sites in Uganda.

      Namuwenge, P M; Mukonzo, J K; Kiwanuka, N; Wanyenze, R; Byaruhanga, R; Bissell, K; Zachariah, R; Makerere University School of Public Health P.O. Box 7072 Kampala Uganda; AIDS Information Centre headquarters, P.O. Box 10446 Kampala, Uganda. (2012-02)
      Among HIV-infected adults attending non-governmental organization voluntary counseling and testing (VCT) sites in Uganda that provide a nine-month course of isoniazid preventive treatment (IPT), we report on loss to follow-up (LTFU) and its associated risk factors. The design was a retrospective cohort study of program data spanning a three year period (2006-2008). A total of 586 IPT patients were enrolled of whom 335 (57.1%) were females with a mean age of 34 years. Of those starting IPT, 341 (58.1%) were lost to follow-up, 197 (33.6%) completed IPT, 29 (4.9%) were discontinued and 19 (3.2%) died. The return rates at one, three, five and seven months were 78.0% (457), 62.1% (364), 52.9% (310) and 33.6% (197) respectively. Being less than 30 years of age, widowed, separated, or divorced were found to be associated with a higher risk of loss to follow-up. Sudden improvement in retention on IPT was observed between the years 2006 and 2007, although causes of the improvement are poorly understood hence the need for more research. At non-governmental VCT sites in Uganda, six out of ten individuals enrolled on IPT are lost to follow-up and efforts to reduce this attrition including systems strengthening might play a critical role in the success of IPT programs.
    • Low Incidence of Renal Dysfunction Among HIV-Infected Patients on a Tenofovir-Based First Line Antiretroviral Treatment Regimen in Myanmar

      Kyaw, Nang Thu Thu; Harries, Anthony D; Chinnakali, Palanivel; Antierens, Annick; Soe, Kyi Pyar; Woodman, Mike; Das, Mrinalini; Shetty, Sharmila; Zuu, Moe Khine Lwin; Htwe, Pyae Sone; et al. (Public Library of Science, 2015)
      Since 2004, Médecins Sans Frontières-Switzerland has provided treatment and care for people living with HIV in Dawei, Myanmar. Renal function is routinely monitored in patients on tenofovir (TDF)-based antiretroviral treatment (ART), and this provides an opportunity to measure incidence and risk factors for renal dysfunction.
