Assignment (MPhil)--University of Stellenbosch, 2006. / ENGLISH ABSTRACT: The aim of this study was to investigate practical methods of monitoring AIDS related wasting and lipodystrophy in a resource-poor clinical setting with HIV infected women as the population group of interest. Measurement of body composition changes using anthropometry is both cost- and time-efficient. Various different skinfolds were taken and two different equations (the equations of Pollock et al. (1975) and Durnin and Womersley (1974) for calculating body fat were used to determine the most promising method or methods of monitoring body composition changes in a clinical setting. Detailed anthropometric measurements were performed, as well as selected measurements for haematological parameters and quality of life (QoL) for a group of 8 participants on antiretroviral medication (ART group) and 6 participants who were not on treatment (TN group). New variables namely, intra-abdominal indicator (IAI) and a percent of ideal body mass to percent of ideal arm circumference ratio (%IBW:%IAC) were investigated as possible indicators of lipodystrophy. Although measurements were taken at various timepoints, three specific time-points were chosen for data-analysis for the ART group and two time points for the TN group. These three time-points were, baseline (on the day of recruitment for TN participants and within one month before the initiation of treatment for ART participants), short-term (2 to 12 weeks after treatment initiation or the baseline measurement or for the ART and the TN participants) and long-term (within one and a half year of treatment initiation for the ART group). ART and TN participants did not differ for many variables at baseline. The major differences between ART and TN were in measured and derived variables of the arm, especially percent of ideal arm circumference (%IAC) and upper arm fat area (UAFA), which were significantly lower in the ART group. CD4+ and QoL improved significantly for the ART participants from baseline to long-term. This was not associated with changes in muscle mass, but rather some fat mass variables. Participants on antiretroviral medication exhibited changes relating to abdominal obesity. It was concluded that antiretroviral therapy contributed greatly to the QoL of the participants and it probably aided in the recovery from wasting for at least one participant in this study. Measures of the arm can be used in a rural clinical setting to effectively monitor patients with regard to AIDS related wasting. The new variables IAI and %IBW:%IAC could be helpful in the monitoring of lipodystrophy and should be investigated in future research. / AFRIKAANSE OPSOMMING: Die doelwit van hierdie studie is om praktiese metodes te ondersoek om VIGS-verwante uittering en lipodistrofie te meet in ‘n plattelandse kliniese omgewing (waar hulpbronne dikwels beperk is) met MIV ge-infekteerde vroue as populasiegroep. Die gebruik van antropometrie om veranderinge in liggaamssamestelling te meet is beide koste- en tydeffektief. Verskeie velvoumetings is geneem en twee verskillende vergelykings (die vergelykings van Pollock et al. (1975) en Durnin en Womersley (1974)) is gebruik om liggaamsvetinhoud te bereken, met die doel om ‘n belowende metode te vind om veranderinge in liggaamssamestelling te meet in ‘n kliniese omgewing. Verskeie antropometriese metings is geneem, sowel as uitgesoekte hematologiese en lewenskwaliteitmetings (QoL) vir ‘n groep van agt deelnemers wat antiretrovirale medikasie ontvang het (ART groep) en ses deelnemers wat nie hierdie behandeling ontvang het nie (TN groep). Nuwe veranderlikes (binnebuikindikator (IAI) en die verhouding van persentasie van ideale liggaamsmassa tot persentasie van ideale armomtrek (%IBW:%IAC)) is ondersoek as moontlike aanwysers van lipodistrofie. Drie spesifieke tydpunte vir die ART groep en twee tydpunte vir die TN groep is gekies uit die verskeie tydpunte waarby metings geneem is, nl. basislyn (gedefinieer as die dag wat TN deelnemers in die studie opgeneem is en 0 tot 4 weke voor die begin van behandeling vir die ART deelnemers), korttermyn (2 tot 12 weke nadat behandeling begin is of na die basislyn meting) en lang-termyn (binne een en ‘n half jaar nadat behandeling begin is vir die ART groep). By die basislyn tydpunt het min van die ART en TN deelnemers se gemete veranderlikes verskil. Die ART en TN groepe het hoofsaaklik verskil ten opsigte van veranderlikes wat betrekking het op die arm, veral persentasie van ideale armomtrek (%IAC) en bo-arm vetarea (UAFA). Hierdie twee veranderlikes was beduidend laer in die ART groep as in die TN groep. CD4+ seltelling en lewenskwaliteit tellings het beduidend verbeter vir die ART deelnemers van die basislyn tot die lang-termyn tydpunt. Hierdie veranderinge is nie samehangend met veranderinge in spiermassa nie, maar eerder met sommige vetmassa veranderlikes. Deelnemers wat antiretrovirale medikasie ontvang het, het veranderinge getoon wat gedui het op ‘n verhoogde neerlegging van vet in die buikarea. Ten slotte is bevind dat antiretrovirale medikasie bygedra het tot die verbeterde lewenskwaliteit van die deelnemers en dat dit waarskynlik ook die omkeer van uittering van ten minste een deelnemer aangehelp het. Daar is ook bevind dat armverwante metinge gebruik kan word in die plattelandse kliniese omgewing om pasiënte suksesvol te monitor ten opsigte van VIGSverwante uittering. Die nuwe veranderlikes, IAI en %IBW:%IAC kan moontlik gebruik word om lipodistrofie-verwante veranderings te meet en die gebruik van hierdie veranderlikes behoort ondersoek te word in verdere navorsing.

Thesis (MPhil)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: The AIDS epidemic has brought out both the best and the worst in people. The disease brings out the best when individuals group together in solidarity to combat the consequences of HIV/AIDS and to support and care for PLWHA. HIV/AIDS also brings out the worst when individuals are stigmatized and ostracized by their loved ones, their family and their communities and discriminated against individually as well as institutionally. This research has reviewed available scientific literature on HIV/AIDS stigma and discrimination. The research has also established HIV/AIDS stigma and discrimination comes in different forms and occurs in different contexts. Stigma and discrimination play a significant role in HIV/AIDS prevention and treatment efforts. Analysis of this research indicates stigma and discrimination has a negative impact on HIV/AIDS prevention and treatment efforts. / AFRIKAANSE OPSOMMING: Die VIGS-epidemie het beide die beste en die slegste in mense. Die siekte bring die beste wanneer individue groep saam in solidariteit die gevolge van MIV / VIGS te bestry en te ondersteun en sorg vir PLWHA. MIV / VIGS bring ook die ergste wanneer individue gestigmatiseer en verstoot deur hul geliefdes, hul familie en hul gemeenskappe en teen gediskrimineer individueel sowel as institusioneel. Hierdie navorsing het hersien dat die beskikbare wetenskaplike literatuur oor MIV / VIGS stigma en diskriminasie. Die navorsing het ook vasgestel dat MIV / VIGS stigma en diskriminasie kom in verskillende vorms voor en kom in verskillende kontekste. Stigma en diskriminasie speel 'n belangrike rol in MIV / VIGS voorkoming en behandeling pogings. Ontleding van hierdie navorsing dui daarop dat stigma en diskriminasie het 'n negatiewe impak op MIV / VIGS voorkoming en behandeling pogings.

Thesis (MFamMed) -- Stellenbosch University, 2012. / ENGLISH ABSTRACT: Background Sub-Saharan Africa has been hard hit by the HIV/AIDS epidemic with an estimated 22.9 million adults infected in 2010. The advent of antiretroviral therapy (ART) has seen significant reduction in mortality from AIDS related illnesses. With the reduction of mortality and the indisputable positive results seen from the use of Anti-retroviral Treatment (ART), the demand both from people living with HIV and health care providers to phase in less toxic ARVs while maintaining simplified fixed-dose combinations has increased considerably. Botswana like most low-resource countries has adapted the WHO recommendation of daily ART as opposed to the previous twice daily HAART. No evidence from resource limited settings has been found that clearly indicates the superiority of regimens based on AZT, d4T or TDF. Aim The primary aim was to compare treatment response between two cohorts. The secondary aim was to compare any association of regimen to age or gender. Objectives To comparatively determine treatment response at 3 months based on immunological response (shown by an increase in CD4 above pre-therapy levels) and viral load response. Methods The study is a retrospective comparative cohort study. Three ART sites were selected from a total of 6 sites. A sample size of 263 was required to achieve a 90% effect power. An equal number of patient records were reviewed per site and each arm had an equal number of reviewed records. A total of 286 patient record files which fit the inclusion criteria were retrospectively analysed and data entered in Excel before being analysed using Statistica Version 10. A p <0.05 represents statistical significance whilst a 95% confidence interval was used for estimation of unknown variables. Results n=263. The overall sample was predominantly male (75.19%). An overwhelming majority (95.88%) of patients in both arms had undetectable viral loads (VL<400). A significant association was found between the regimen and viral load (p=0.0315-Pearson Chi Test). The difference in CD4 between the two arms was not statistically significant (p=0.655890-ANOVA). A positive association was found between the regimen and gender (p=0.03190-Pearson Chi Test). This was possibly owing to the high numbers of males and no statistical adjustment to gender made. No association was found in the difference in CD4 cell counts for regimen and gender (p=0.612191-Anova). Conclusion Treatment response at 3 months post initiation between once daily and twice daily HAART in Gaborone Botswana by use of virologic and immunologic response has been shown to be comparable. The use of one regimen over the other as first line as recommended by WHO and the subsequent adoption of the current first line regimen by the Botswana Ministry of Health may be justified. This study has therefore reinforced the applicability of previous findings in other settings of this recommendation. As part of the targeted audience and indeed as a partner in the care and management of HIV, the responsibility to ensure applicability of the recommendations set out for resource limited areas has been achieved through this study. However, bigger randomized trials in resource limited settings are needed to justify and accredit these findings as well as add to the evidence obtained in developed countries.

Thesis (MPhil)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: This study is qualitative research that aims to identify the effect of corruption on HIV/AIDS donor funds in Namibia in order to provide guidelines to policy makers in relations to the regulation of HIV/IDS donor funding. Henceforth, in–depth interviews with open ended questions were used with Government, civil society and donor agencies’ senior officials to obtain data. Additionally, institutional permission was granted from the identified institutions who participated in the research. An inductive analysis was used which required data to be categorised and developing themes from the data. Respondents reported lack of national donor specifications in the field of HIV/AIDS as a serious problem to donor funds in Namibia. However, respondents indicated their organisations had proper management systems in place which included, annual audits, sufficient personnel and monitoring and evaluation. Withdrawal of donor funding has been on the increase due to corrupt practices in some funded organisation and this is mostly affecting people living with HIV/AIDS. Respondent reported there is a need to strengthen the existing umbrella body and improve accountability. The findings of the study show the effect of corruption on HIV/AIDS donor funds in Namibia is the withdrawal of HIV/AIDS donor supports by several donor agencies which has led to numerous donor funded institutions closing down and a number of employee losing their employment. Lack of national HIV/AIDS donor specifications is viewed as a loophole for corruption for many funded organisations as there are no national accountability systems in place in relation to HIV/AIDS donor funds in Namibia. / AFRIKAANSE OPSOMMING: Nie beskikbaar.

The objective of this treatise is to establish whether a right to social security exists in South Africa, which would entitle HIV positive persons in South Africa citizens to medical care. A study was made of various articles in journals and on the Internet to determine the South African government's policy on a right to social security and to providing medical treatment. It was found that South Africa lacks an integrated, holistic approach to social security and does not guarantee the right to social security, merely the right to have access to social security. The same was found with the right to medical care. Although there seems to be a general right to medical care which extends to and includes HIV-positive patients, the state merely guarantees the right to apply for medical treatment but does not guarantee the granting thereof. It is submitted that the Department of Health's refusal to implement a vertical transmission prevention programme and the failure to offer treatment as an alternative, for whatever reason, is "penny wise and pound foolish". In the long run more money is spent dealing with pediatric AIDS. It was further found that although the government attempted to lay a groundwork with the formulation and acceptance of the national AIDS plan, the successful implementation thereof is seriously hindered due to the lack of inter- and intra-departmental collaboration, essential health services and funding.

This study was conducted to determine retention rate and factors associated with loss to follow-up (LTFU) of adult pre-ART patients in St. Luke hospital, Ethiopia. Cross-sectional study with quantitative and qualitative data collection techniques was used. Review of patient records, focus group discussions and review of program guidelines was conducted to determine level of adherence among pre-ART patients. In addition, pre-ART service quality and perceived reasons for discontinuation was explored. The study revealed that only 38.2% of the 335 patients enrolled in the pre-ART care were retained after 12 months of follow-up in the program. More than half (55.6%), of the LTFU occurred during the first 6 months of follow-up. Fear of discrimination, high transportation cost and mistrust in the pre-ART service were perceived reasons for LTFU. Absences of clear pre-ART service package and implementation guideline were also identified as important factors that may be related to LTFU. The findings call for improved quality of care and a better pre-ART service packaging that will address the gaps identified in order to increase patient retention. / Health Studies / MA (Public Health)

The purpose of this study is to explore the EAP environment and provide a better understanding of the related roles of the Employee Assistant Practitioners/Professionals (EAPs) in respect of their treatment of various forms of illnesses in the workplace – particularly HIV and AIDS. The EAP role is not aligned to any individual profession, as it is designed to match employees’ holistic needs. It is in this context that the repertoire of EAP roles would include caring, psycho-social, therapeutic and technical skills. The EAP role is therefore endowed with the potential to meet a range of inter-departmental and multi-disciplinary needs – such as Nursing, Allied Health Professions, and Healthcare Sciences. A generic Assistant Practitioners Performance Management system (scorecard) had to be developed and agreed to with the City of Johannesburg’s (CoJ) Management in order to maintain consistency when developing APE programmes and roles. Notwithstanding the fact that the Employee Assistant Practitioners do also address the growing HIV/AIDS concerns in the workplace – including psycho-social problems of employees and their families – there is minimal acknowledgment of the EAPs’ roles, and little recognition of their welfare and well-being programmes. Drawing eclectically from various inter-related disciplinary terrains, the study centripetally explores the roles of EAPs as well as HIV/AIDS frameworks in the workplace. Quantitative and qualitative descriptive research methods were employed to assess challenges encountered by the City of Johannesburg (C.o.J) employees and their dependants. Questionnaires were used for the data collection of this study. The repertoire of participants in the study (n=55) comprised of doctors, social workers, nurses, HR officers, and other CoJ employees themselves. vi The questionnaire became the pivotal quantitative data analysis reference point ias it focused on numbers or quantities, and less on the qualitative analysis, which focused on differences in quality. The results of the study are based on numeric analysis and statistics to quantify the qualitative analysis. The prevalence of fewer participants was largely influenced by the depth of the data collection process, which did not allow for large numbers of research participants. The findings of the study revealed, amongst other factors, that there was an unsurpassed need to integrate different HIV/AIDS frameworks in order that the roles of EAPs becomes more effectively and efficiently defined and executed. The roles of EAPs were hitherto not well defined, resulting in duplication and confusion of service delivery to some employees utilising the EAP services. However, some of the EAP roles are highly appreciated and increasingly supported by managers and employees. Based on the findings of the study, recommendations were made for clarifying and extending the criticality of EAP roles and functions. / Health Studies / Ph. D. (Health Studies)

The purpose of the study was to evaluate the IMB skills model for its relevance to the Ethiopian context. According to the model, adherence-related information and motivation work through adherence-related behavioural skills to affect adherence to ART. Quantitative, analytical, observational, cross-sectional, institution-based study was conducted to evaluate the model by assessing those patients who have and do not have the right information, motivation, and behavioural skills whether they have or do not have good adherence to ART. Data was collected using structured questionnaires where a total of 400 randomly selected participants provided data on adherence-related information, motivation and behavioral skills as well as adherence behavior per se. Data was analysed using the Statistical Package for Social Sciences (SPSS) version 20.0. Both descriptive and inferential statistics used in the study. Only 90.75 % of the total sample population reported ART adherence rate of more than or equal to 95% in this study. Free and restricted model tests, through bivariate and multivariate analyses, used to assess the propositions of the IMB model of ART adherence and provided support for the interrelations between the elements proposed by the model. The study has supported the applicability of the IMB model of adherence to the Ethiopian context highlighting its application in adherence-promotion intervention efforts. The findings revealed the need for on-going educational, informational and other interventions to address the knowledge, motivation and adherence behavioural skills of patients in order to improve the current levels of ART adherence behaviour. / Health Studies / D.

This thesis argues that corporations qua corporations are moral agents sui generis and hence capable of being held morally responsible. I argue that corporations qua corporations are responsible for the actual and foreseen consequences of their actions. I analyse normative theories and the different proscriptive responsibilities they place on moral agents and hence corporations. I examine Kantianism, utilitarianism and virtue ethics. I argue for a unique normative ethical theory that incorporates reasoning from all three of the normative theories. I argue for a broad range of reasons to factor into deciding whether an act is ethical or not. One of the claims of this thesis is that ethical theories must incorporate an agent’s motivation, intention and character traits as relevant to deciding on whether an action is ethical or not. My thesis argues for an indispensable role for the virtues while at the same time incorporating impartial beneficence and universal rationality from utilitarianism and Kantianism. This position I, following the literature, refer to as moderate virtue theory. Having established corporate qua corporate responsibility I question the pharmaceutical corporation’s practice of patenting life saving medication during a state of pandemic in poor countries. The moderate virtue theory position prioritises contexts and the actual human condition and criticises normative theories that attempt to give universal, abstracted answers to ethical problems. It is for this reason and the current (2003) HIV/AIDS pandemic that I focus on a particular context. I examine the practice of patenting life saving medication within South Africa and argue, applying moderate virtue theory, that this act cannot be justified. I argue that a pharmaceutical corporation that patents life saving medication in South Africa cannot justify that action and thus is morally responsible for that action. I also argue that corporations patenting HIV/AIDS medication in South Africa have unethical motivations and intentions.

South Africa has an estimated 920 000 patients on antiretrovirals (ARVs), the largest number of patients in any country. ARV therapy demands adherence levels in excess of 95% to avoid development of drug resistance, but adherence to ARV therapy is estimated to be only between 50% and 70%. Poor medication adherence is acknowledged as a major public health problem, reducing the effectiveness of therapy and promoting resistance to ARVs. More than two thirds of the South African population have marginal reading skills and this significantly influences a patient’s ability to read and understand health-related information. Patient education materials tailored for the South African population could be a useful aid in facilitating communication with patients and perhaps impact positively on their medicine-taking behaviour. This behaviour is influenced by patient knowledge, beliefs, attitudes and expectations and includes self-management, self-efficacy and adherence. Self-efficacy, which refers to patient confidence in the ability to self-manage medicine taking, is a key factor influencing adherence. This study aimed to develop illustrated patient information leaflets (PILs) and medicine labels for all first-line ARV regimens used in the public health sector in South Africa and, using a randomised control study design, to investigate the impact of these illustrated information materials on knowledge, medication-taking behaviours and health outcomes in HIV/AIDS patients taking ARVs. To achieve this aim, the objectives were to assess HIV/AIDS and ARV-related knowledge, as well as self-efficacy and adherence to ARV therapy; to assess the influence of demographic variables on knowledge, adherence and self-efficacy; to assess the influence of the information materials on knowledge, self-efficacy and adherence and to assess the association of knowledge with health outcomes. Medicine labels and PILs, both English and isiXhosa, were developed for ARV regimens 1a, 1b, 1c and 1d. The 8-item Morisky Medication Adherence Scale (MMAS-8) and HIV Treatment Adherence Self Efficacy Scale (HIV-ASES) instruments for measuring respectively adherence and self-efficacy, were modified to optimize clarity, simplicity and cultural acceptability and were translated into isiXhosa using a multi-stage translation-back translation. The questions and the rating scales, for both the MMAS and HIV-ASES, underwent preliminary qualitative evaluation in focus group discussions. Patients were recruited from local Grahamstown clinics. A pilot study to evaluate applicability of the instruments was conducted in 16 isiXhosa AIDS patients on ARVs and the results from this study informed further modifications to the instruments. One hundred and seventeen patients were recruited for the randomised control trial and were randomly allocated to either control group (who received standard care) or experimental group (who received standard care as well as pictogram medicine labels and the illustrated PIL). Interviews were conducted at baseline and at one, three and six months. Data were analysed statistically using the t-test, chi-squared test and ANOVA (Analysis of Variance) at a 5% level of significance. Correlations were determined using Pearson and Spearman rho correlations. Approval was obtained from Rhodes University Ethical Standards Committee, Settlers Hospital Ethics Committee and the Eastern Cape Department of Health. The results of this research showed that illustrated PILs and medicine labels enhanced understanding of HIV/AIDS and ARV information, resulting in a mean overall knowledge score in the experimental group of 96%, which was significantly higher than the 75% measured in the control group. Variable knowledge scores were measured in three areas: baseline knowledge of general HIV/AIDS-related information was good at 87%, whereas knowledge scores relating to ARV-related information (60%) and side-effects (52%) were lower. These scores improved significantly in the experimental group over the 4 interviews during the 6 month trial duration, whereas in the control group, they fluctuated only slightly around the original baseline score. There was no significant influence of gender on knowledge score, whereas health literacy, education level and age tested (at one and three months) had a significant influence on knowledge. Self-efficacy and adherence results were high, indicating that the patients have confidence in their ability to adhere to the ARV therapy and to practice optimal self-care. Age, gender and education, in most cases, significantly influenced self-efficacy, but were found to have no effect on adherence. The CD4 count improved over the trial duration which may have been influenced by a number of factors, including better knowledge of ARVs and improved adherence. No significant parametric correlation was found between knowledge score and change in CD4 count, however, Spearman's rho showed significance (rs=0.498; p=0.022). Both patients and healthcare providers were highly enthusiastic about the illustrated labels and PILs, and indicated their desire for such materials to be routinely available to public sector HIV/AIDS patients. The isiXhosa version of the PIL was preferred by all the patients. These simple, easy-to-read leaflets and illustrated medication labels were shown to increase understanding and knowledge of ARVs and HIV/AIDS in low-literate patients, and their availability in the first-language of the patients was central to making them a highly useful information source.
