The effects of HIV/AIDS epidemic on teachers and learners of one secondary school in Mthatha District

Ntshanga, Nandipa January 2013 (has links)
The aim of this research study was to investigate the effects of HIV/AIDS on teachers and learners of one Secondary School in Mthatha District of Eastern Cape, South Africa. The research design used was a case study; both quantitative and qualitative techniques were employed. The research was conducted in one secondary school, where data was collected using the interview schedules and the questionnaires. The teachers and learners were the respondents. Close-ended responses were analysed using Statistical Programme for Social Sciences (SPSS) computer software. Open-ended responses and interviews were analysed manually using sentence analysis, themes, categories and pattern. Interview responses were also analysed and interpreted using descriptions. From the analysis and interpretation of results, the following main findings emerged: HIV/AIDS has a devastating and deadly effect on both learners and teachers such as:-early sick pensions, redeployments, high teacher death rate, high learner death rate and learner absenteeism. Learner and teacher absenteeism trough HIV/AIDS epidemic, learner drop-out from school because of HIV/AIDS, non-fulfillment of future goals by the learners were discovered by the researcher as some of the findings from the study. From the findings it emerged that HIV/AIDS has devastating and deadly effect on both learners and educators. Support on those who are affected by HIV/AIDS epidemic is recommended by the researcher and the strategies that can be used to control HIV/AIDS epidemic.

A systematic review of available information concerning the economic impact of HIV/AIDS on Swaziland

Muwanga Fred Tusuubira 08 November 2006 (has links)
A research report submitted to The Faculty of Health Sciences, University of Witwatersrand, in fulfillment of the requirements for the degree Of Masters in Public Health Johannesburg 2005 / ABSTRACT Swaziland is currently faced with a deepening HIV/AIDS epidemic. A systemic review of available information concerning the economic impact of HIV/AIDS on Swaziland was undertaken to collate data and document this impact in order to inform decision makers and planners. The methodology for the systematic review was based on the guidelines described in the Cochrane Reviewers’ handbook. HIV/AIDS has significantly increased the vulnerability of affected Swaziland rural households to environmental shocks. There is an increased burden of orphans due to HIV/AIDS, reduced household labour and income as adults die of AIDS. HIV/AIDS has reduced farm productivity leading to worsening of food insecurity and poverty in affected households. Due to HIV/AIDS, absenteeism in Swaziland organizations has increased by 20- fold. HIV/AIDS is currently the leading cause of death accounting for over 60 percent of all employee deaths. Organisations that have implemented HIV/AIDS workplace responses have been less affected. The micro-sector is the worst affected and it is recommended that policy makers ensure that this sector is protected from the negative impact of HIV/AIDS. The epidemic of negative impacts of HIV/AIDS in Swaziland has not yet reached the peak.

The psycho-educational needs of children orphaned by AIDS as perceived by their caregivers / Marieke Cornelia van Rooyen

Van Rooyen, Marieke Cornelia January 2011 (has links)
During the past decade, South Africa has become the country with the highest number of HIV/AIDS infections in the world. In the wake of the widely spread HIV/AIDS epidemic in South Africa, hundreds of thousands of children are left parentless. Since limited research exists on the psycho-educational needs of children orphaned by AIDS in South Africa, the focus of this study was on their psycho-educational development. A literature study was conducted to investigate the HIV/AIDS epidemic in South Africa and its consequences for the psycho-educational development of AIDS orphans. A qualitative investigation was undertaken and interviews were conducted with caregivers of AIDS orphans at two care centres in rural KwaZulu-Natal. The aim of the investigation was to identify the psycho-educational needs of AIDS orphans as perceived by their caregivers. Moreover, the investigation also aimed at identifying factors that impede the psycho-educational development of AIDS orphans, and to determine the extent to which these day care centres meet the psycho-educational needs of these orphans. The following psycho-educational needs of AIDS orphans emerged from the investigation: - the need to socialise and communicate - the need to cope with parental death - the need for acceptance - the need for security and care - the need for love and belonging - the need to deal with negative emotions Physical and material needs were added to the above needs, since these were frequently mentioned during the course of the interviews. Factors that seriously impeded the psycho-educational development of AIDS orphans were abuse and neglect. The investigation also revealed that the care centres were to a large extent able to meet a broad spectrum of these orphans’ psycho-educational needs, especially at the care centre where the AIDS orphans were able to sleep over and received the full-time attention caregivers. Since the extended family system can no longer fully carry the burden of hundreds of thousands of AIDS orphans in South Africa, care centres situated in the affected communities can offer a viable alternative to traditional models of care. The study emphasised the need for further research on the needs of AIDS orphans as well as increased support of AIDS orphans on local, provincial and national levels. / MEd (Learner support), North-West University, Potchefstroom Campus, 2012

Phenotypic and functional characterization of cytotoxic T lymphocytes in HIV-1 infected South African adults

Pillay, Santhoshan Thiagaraj 12 1900 (has links)
Bibliography / Thesis (MScMedSc (Pathology. Medical Virology))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: In just 25 years since the first reported cases in 1981, the number of Human Immunodeficiency virus (HIV) infected people has risen to 65 million, and over 25 million have died of acquired immunodeficiency syndrome (AIDS). Sub-Saharan Africa accounts for 67% of all people living with HIV and 72% of deaths in this region were AIDS related. Tuberculosis (TB) is one of the most common opportunistic infections in AIDS patients, particularly in developing countries, where 60 - 70% of TB cases occur in HIV-1-infected persons. HIV-1 is a high risk factor for the development of TB, the reactivation of a latent Mycobacterium tuberculosis infection and also progressive TB. CD8+ Cytotoxic T Lymphocytes (CTL) are pivotal in the host immune response to HIV infection. CTL are associated with resolution of acute infection and with reduction in viral load. Studies in macaques and humans indicate the importance of CTL in the control of HIV infection, where reduction in CD8+ T cell number has been correlated with progression to AIDS. The current study was a cross-sectional descriptive study of CD8+ T cells of HIV+ adult South Africans with and without TB co-infection (TB disease). The cohort consisted of anti-retroviral therapy (ART) naive patients and all CTL analyses were carried out on peripheral blood mononuclear cells (PBMCs). A total of 60 South African adults from the Western Cape were utilized in this study, including 15 healthy controls; 30 HIV+TB-individuals and 15 HIV+TB+ individuals. Expression of phenotypic, activation and functional markers were investigated by flow cytometry with the use of fluorochomeconjugated antibodies. The markers examined included the novel activation marker CD137, the CTL associated markers Perforin, Granzyme A, CD107a/b, Fas (CD95), and FasL (CD95L), intracellular cytokines IFN-y and TNF-a and the chronic HIV CTL dysfunction marker PD-1. HIV infection alone was associated with increased baseline expression of TNF-a, Perforin, Granzyme A, PD-1, Fas (CD95), and FasL (CD95L), but not CD137(4-1BB) or IFN-y as compared to uninfected controls. TB co-infection resulted in further increased baseline expression of TNF-a, perforin, PD-1, FasL (CD95L), as well as increased IFN-y. HIV-1 antigen (gag)-specific stimulation in vitro indicated that in HIV infection was associated with antigen-specific upregulation of activation and cytotoxicity markers CD137, IFN-y, TNF-a, Fas, FasL and CD107a/b. In TB co-infection a reduction in antigen-specific degranulation (CD107a/b up-regulation) and also Fas and FasL expression was observed. TB co-infection (in the form of active pulmonary TB) reduced antigen-specific CTL functional activity, but simultaneously there was an association with increased baseline PD-1 expression and also cytolytic marker expression (Fas, FasL, TNF-a). These cytolytic markers could be involved in non-antigen-specific bystander target cell death. The expression of the co-stimulatory molecule CD137 appeared to correlate with interferon-y production and levels of degranulation, confirming its usefulness as a putative surrogate marker of functional responsiveness. These data indicate that in addition to impacting on CD4 T cell function, TB co-infection leads to higher baseline expression of CTL-associated markers, but to dysfunctional antigen-specific CTL responses. / AFRIKAANSE OPSOMMING: Slegs vyf en twintig jaar na die eerste berigte van die menslike immuniteitsgebrekvirus (MIV) in 1981, het die getal MIV-geinfekteerde individue gestyg tot 65 miljoen en het meer as 25 miljoen mense alreeds gesterf aan die verworwe immuniteitsgebrek sindroom (VIGS). Sub Sahara Afrika maak 67% uit van alle HIV gevalle en het `n MIVverwante doodsyfer van 72%. Een van die algemeenste opportunistiese infeksies in VIGS pasiente is Tuberkulose (TB). In ontwikkelende lande, veral, kom 60-70% van TB gevalle voor in MIV-1 geinfekteerde individue. MIV-1 is `n hoe risiko faktor vir die ontwikkeling van TB, die heraktivering van latente Mycobacterium tuberculosis infeksie en progressiewe TB. Die CD8+ sitotoksiese T Limfosiete (STL) se immuun reaksie teen `n MIV infeksie is noodsaaklik en word geassosieer met `n resolusie van die akute infeksie en `n afname in viruslading. Studies in die mens en macaque het getoon dat sitotoksiese T limfosiete belangrik is vir die beheer van MIV infeksies aangesien die afname in CD8+ sel getalle korreleer met die verloop tot VIGS. Hierdie deursnit-beskrywende studie het die CD8+ T selle van MIV+ volwasse Suid-Afrikaners, met of sonder`n TB mede-infeksie, ondersoek. STL analise is gedoen op die perifere bloed mono-nuklere selle (PBMS) van pasiente wat geen teen-retrovirale terapie (TRT) ontvang het nie. `n Totaal van sestig Suid-Afrikaanse volwassenes van die Wes-Kaap het deelgeneem aan die studie wat 15 gesonde kontroles; 30 MIV+TBen 15 MIV+TB+ individue ingesluit het. Die uitdrukking van fenotipiese, aktiverings en funksionele merkers is ondersoek deur middel van vloeisitometrie en fluorochroomgekonjugeerde teenliggaampies. Laasgenoemde het ingesluit die nuwe aktiversingsmerker CD 137, die STL geassosieerde merkers Perforien en Gransiem A, CD 107a/b, Fas (CD95) en FasL (CD95L), intrasellulere sitokiene IFN-y en TNF-a en PD-1, die merker vir chroniese MIV CTL disfunksie. Daar is gevind dat `n TB mede-infeksie (in die vorm van aktiewe pulmonere TB) die antigeen-spesifieke STL funksie verlaag en terselftertyd `n verhoging in die uitdrukking van PD-1 en sitolitiese merkers (Fas, FasL, TNF-a) bewerkstellig. Hierdie sitolitiese basislyn merkers is moontlik betrokke by die dood van nie-antigeen-spesifieke omstander teiken selle. Die uitdrukking van die mede-stimulatoriese molekule CD 137 blyk om te korreleer met die produksie van STL IFN-y en die vlakke van degranulasie. Dit bevestig die merker se bruikbaarheid as `n gewaande surrogaat merker vir funksionele reaksies. Die data toon verder dat `n TB mede-infeksie nie net `n effek het op die CD4 T sel funksie nie, dit lei ook tot `n verhoogde basislyn uitdrukking van STLgeassosieerde merkers, maar met disfunksionele antigeen-spesifieke STL reaksies. Hierdie studie het bepaal dat `n MIV infeksie verbind word met `n toename in die basislyn uitdrukking van TNF-a, Perforien, Gransiem A, PD-1, Fas (CD95) en FasL (CD95L). Dit is egter nie die geval wanneer die uitdrukking van CD 137 (4-1BB) of IFN-y vergelyk word met nie-geinfekteerde kontroles. `n TB mede-infeksie het `n verdere toename in die uitdrukking van TNF-a, Perforien, PD-1, FasL (CD95L) getoon, asook `n verhoging in IFN-y vanaf die basislyn. In vitro MIV-1 antigeen (gag)-spesifieke stimulasies het aangedui dat `n MIV infeksie met die antigeen-spesifieke op-regulasie van aktiverings en sitotoksiese merkers CD137, IFN-y, TNF-a, Fas, FasL en CD107a/b geassosieer word. In `n TB mede-infeksie, is `n verlaging van antigeen-spesifieke degranulasie (CD 107a/b op-regulasie) asook die uitdrukking van Fas en FasL waargeneem. / The Poliomyelitis Research Foundation / The National Health Laboratory Service
