The study analysed and compared data from patients' medical and pharmacy refill records to identify correlations between CD4 cell counts and adherence to antiretroviral drugs at Katutura Intermediate Hospital (KIH) in Windhoek, Namibia. The study investigated whether the pharmacy refill adherence measurement methodology could predict immunological recovery through increased CD4 cell counts. There was a positive but weak relationship between adherence and CD4 cell counts. Although the pharmacy refill records could predict immunological response it was not sensitive enough and should be used in combination with other adherence measurement tools. / Public Health / M.A. (Public Health)

This study attempted to identify personal (patient-related) factors influencing anti-retroviral therapy (ART) adherence in Addis Ababa, Ethiopia. A quantitative, descriptive, cross-sectional and analytical design was used. Structured interviews were conducted with 355 ART patients. The findings revealed that stigma, discrimination, depression and alcohol use negatively affected patients’ ART adherence levels. However, patients’ knowledge levels had no influence on their ART adherence levels, contrary to other researchers’ reports. Addressing stigma and discrimination at community levels might enhance patients’ abilities to take their medications in the presence of others. Healthcare professionals should be enabled to diagnose and treat depression among ART patients during the early stages. Non-adherent ART patients should be counseled about possible alcohol abuse. / Health Studies / M.A. (Public Health with specialisation in Medical Informatics)

This quantitative study sought to identify and describe factors influencing HIV disclosure and sexual practices among 340 PLWHA on ART at Mbabane National Referral VCT/ART Centre, Swaziland. Data were collected using a structured questionnaire. A high general HIV disclosure rate (94.1%; f=320; N=340) was observed of which 57.5% (f=184; n=320) was to sexual partners. X2 procedures indicate an association with gender, residential region, religion, and period of being on ART. The majority (70.2%; f=179; n=255) of the respondents used condoms all the time to avoid infecting their sexual partners (99.2%; f=243; n=245) and to avoid contracting STIs (99.2%; f=243; n=245). X2 procedures indicate an association with gender, residential region, marital status, number of sexual partners, knowledge of the HIV status of sexual partners and period of being on ART. The single leading reason for not using the condom was sexual partners’ refusal to use condoms (85.7%; f=54; n=63). / Health Studies / M.A.(Health Studies)

The aim of this study was to assess the extent on how effective was the prevention of mother-to-child transmission of Human Immunodeficiency Virus (HIV) infection at Oshakati District Health Centre. Explanatory survey was used to conduct the research. A total of 160 nurses experienced in prevention of mother-to-child transmission and women who attended antenatal care and post natal care services participated in the study. Respondents expressed unsatisfactory with the promoting involvement of male partners, high quality voluntary counselling and testing services, couple counselling and testing, integration of Highly Active Antiretroviral Therapy services, administration of short course of Zidovudine to pregnant mothers and the provision of antiretroviral drugs to infants. Therefore, promoting involvement of male partners, couple counselling and testing, administration of short course of Zidovudine to pregnant mothers and educating women about exclusive breastfeeding prior to delivery are some of recommendations for effective prevention of mother-to-child transmission of HIV infections. / Health Studies / (M.A. (Public Health))

This study was done to assess the quality of life (QOL) of people living with HIV and AIDS (PLWHA) in Swaziland who are on antiretroviral therapy (ART). No study has been done on QOL of PLWHA in Swaziland who are on ART since it started to be administered in Swaziland in 2001. A qualitative, exploratory, descriptive, and contextual design was used to assess QOL of PLWHA in Swaziland who are on ART. Twenty-four PLWHA were purposely selected to participate in the study. Methods of data collection used were semi-structured individual in-depth interviews, focus group discussions, and observations. The data (tape-recorded interviews and discussions, and field notes) were transcribed verbatim for data analysis. Data analysed was done using Tesch’s framework of data analysis as described in Creswell (2002:256-283). The research findings are reflected, with the six domains of QOL identified through a literature review and validated by nurses’ expertise. These domains are the physiological, psychological, spiritual, socio-economic, cognitive, and environmental domains.The study revealed that PLWHA in Swaziland are faced with many challenges concerning ART, namely: inability to meet their nutrition needs, non-adherence to ART, experience of disfiguring side effects of ARVs, inconsistent condom use, experience of stigma and discrimination, depression, difficulty in accepting and coping with ARVs, lowered self-esteem, a negative influence of some religions on ART, a lack of financial support, poor support systems, poor understanding of ARVs, negative thoughts about HIV and AIDS and ART, an unsatisfactory health care delivery system, a negative influence of culture on ART, and violation of the rights of PLWHA. These challenges negatively influence the QOL of PLWHA and hence the study concluded that PLWHA in Swaziland who are on ART have a poor QOL. Conclusions drawn from the data analysis reveal that PLWHA in Swaziland are powerless to deal with the above challenges and improve their QOL. The researcher, therefore, developed guidelines to empower PLWHA to deal with these challenges and adhere to ART, thus improving their QOL. Recommendations were made with regard to nursing practice, nursing education, and further nursing research. / Health Studies / D. Litt. et Phil. (Health Studies)

M.A. (Social Behaviour Studies in HIV/AIDS) / This study sought to investigate factors that influence adherence to treatment amongst rural people living with HIV and accessing antiretroviral therapy (ART) at Shongwe hospital in Mpumalanga. Both quantitative and qualitative methods were used. From patients’ case files, a sample of twenty-eight respondents was recruited for the completion of questionnaires. A focus group discussion with nine participants was held, followed by qualitative interviews with three key informants. Findings indicated that a complex web of factors unique to each patient’s social context plays a role in determining whether or not patients adhere to their regimens. Obstacles to adherence are poor social support, problems relating to disclosure, unemployment and economic hardship, traditional and religious beliefs, the quality and nature of adherence counselling and treatment side effects. / Sociology

The purpose of this study was to determine factors affecting non-adherence to Anti-retroviral therapy among AIDS patients. A cross sectional quantitative survey, was used. Structured interviews were conducted with 300 ART patients. Data were analysed using SPSS version 13 and presented in charts, graphs and frequency tables. Motivators of good adherence were identified as disclosure of HIV positive status to more than one person, frequent adherence counselling, self-efficacy to adhere to ART, positive interactions between patients and healthcare providers; and using an adherence partner. Barriers to adherence were forgetfulness, transportation costs to and from the clinic, time away from work and side effects. There was a strong positive correlation between adherence, CD4 counts and viral load. Adherence was closely tied to immunologic and virologic improvements. Respondents with poor adherence were likely to have unsuppressed viral loads (OR 12.98, 95%, CI 4.9-34). / Health Studies / Masters of Public Health

This study assessed healthcare providers’ knowledge, attitudes and practices towards IPT provision for people living with HIV (PLHIV) in Addis Ababa, the capital city of Ethiopia. A quantitative, descriptive, cross-sectional study design was used for the study and data was collected using a self-administered questionnaire from 104 clinicians working in ART clinics. The findings show that healthcare providers who participated in this study had a mean value of high knowledge, positive attitude and good practice towards IPT provision for PLHIV. Significant association was found between knowledge and attitude (P=0.000) but no significant associations were found between knowledge and practice, attitude and practice as well as between the type of facility (public/private) and level of practice. This implied that, the low level of IPT implementation in Addis Ababa doesn’t seem due to health care providers’ lack of knowledge and resistance to provide IPT for people living with HIV. As a result, the researcher recommends for further researches of other possible factors like; the reliability of IPT information/data management, drug supply and the leadership and governance of the health system that IPT program is a direct concern. / Health Studies / M.

The purpose of the study was to describe factors contributing to mortality among HIVinfected people on Isoniazid Preventive Therapy (IPT) in Botswana. A quantitative, explorative, descriptive study was used and 80 records of deceased IPT respondents were reviewed through the use of a checklist. The demographic factors, baseline physical examination, hospitalisation and drug history were taken into consideration. Out of the deceased patients, 75% were female. The major findings showed that 100% (N=80), the most highly indicated causes of death were gastroenteritis (18.75%), cryptococcal meningitis (17.5%) andpneumonia (16.25%). Of the patients (28.75%) who died before completing the six months of IPT. The causes of death were gastroenteritis (21.7%), symptoms and signs of bacterial pneumonia (17.4%), cryptococcal meningitis (13%), Pulmonary Tuberculosis (PTB) (13%), septicaemia (13%), and murder (13%). It has been recommended that there should be reorganisation of services of care for HIV-infected persons, such as provision of Cotrimoxazole Prophylaxis Therapy (CPT) and Antiretroviral Therapy (ART) to ensure holistic approach care. The future study should include HIV-infected children on IPT using the same or modified objectives. The conclusion drawn was that disintegrated interventions of IPT, CPT and ART and lack of holistic care for PLHIV lead to opportunistic infections that caused mortality on patients on IPT. / Department of Health Studies / M.A. (Public Health)

Le virus de l'immunodéficience humaine (VIH) est à l’origine d’une infection chronique, elle-même responsable du développement du syndrome d'immunodéficience acquise (SIDA), un état de grande vulnérabilité où le corps humain est à la merci d’infections opportunistes pouvant s’avérer fatales. Aujourd’hui, 30 ans après la découverte du virus, même si aucun vaccin n’a réussi à contrôler la pandémie, la situation s’est grandement améliorée. Conséquemment à l’arrivée de traitements antirétroviraux hautement actifs (HAART) à la fin des années 1990, la mortalité associée au VIH/SIDA a diminué et un plus grand nombre de personnes vivent maintenant avec l'infection. La présente thèse avait pour objectif d’aborder trois situations problématiques, en dépit de l’efficacité reconnue des HAART, plus particulièrement la faible charge virale persistante (LLV) et sa relation avec l’échec virologique, ainsi que les effets de certains antirétroviraux (ARV) sur les fonctions rénale et hépatique. Les objectifs précis étaient donc les suivants : 1) étudier le risque d’échec virologique à long terme chez les patients sous HAART dont la charge virale est indétectable comparativement aux patients affichant une LLV persistante; 2) évaluer sur le long terme la perte de fonction rénale associée à la prise de ténofovir (TDF) 3) étudier sur le long terme l'hyperbilirubinémie associée à la prise d’atazanavir (ATV) et ses autres déterminants possibles. Afin d’atteindre les trois objectifs susmentionnés, une cohorte de 2 416 patients atteints du VIH/SIDA, suivis depuis juillet 1977 et résidant à Montréal, a été utilisée. Pour le premier objectif, les résultats obtenus ont montré un risque accru d’échec virologique établi à >1000 copies/ml d’ARN VIH chez tous les patients qui présentaient une LLV persistante de différentes catégories durant aussi peu que 6 mois. En effet, on a observé qu’une LLV de 50-199 copies/ml persistant pendant six mois doublait le risque d’échec virologique (Hazard ratio (HR)=2,22, Intervalle de confiance (CI) 95 %:1,60–3,09). Ces résultats pourraient modifier la façon dont on aborde actuellement la gestion des patients affichant une LLV, et plus particulièrement une LLV de 50-199 copies/ml, pour laquelle aucune recommandation clinique n’a encore été formulée en raison du manque de données. Pour le deuxième objectif, on a observé une augmentation du risque de perte de fonction rénale de l’ordre de 63 % (HR=1,63; 95% CI:1,26–2,10) chez les patients sous TDF comparativement aux patients traités avec d’autres ARV. La perte de fonction rénale directement attribuable à la prise de TDF, indique que cette perte est survenue au cours des premières années de l’exposition du patient au médicament. D’une perspective à long terme, cette perte est considérée comme modérée. Enfin, pour ce qui est du troisième objectif, on a constaté que l’incidence cumulative d’hyperbilirubinémie était très élevée chez les patients sous ATV, mais que cette dernière pouvait régresser lorsque l’on mettait fin au traitement. L’hyperbilirubinémie à long terme observée avec la prise d’ATV n’a été associée à aucun effet néfaste pour la santé. Dans l’ensemble, la présente thèse a permis de mieux comprendre les trois situations problématiques susmentionnées, qui font actuellement l’objet de débats au sein de la communauté scientifique, et d’éclairer sous un jour nouveau la gestion des patients séropositifs sous traitement médicamenteux. / Human immonudeficiency virus (HIV) is a virus causing a chronic infection responsible for Acquired Immunodeficiency Syndrome (AIDS), a state of vulnerability of the body where different opportunistic infections will ultimately be fatal. About 30 years after the discovery of the virus, even if no vaccine is available to control the pandemia, situation has changed for the best. With the arrival of highly active anti-retroviral therapy (HAART) in the late 90's, a reduction in HIV/AIDS mortality rate and growing number of persons living with the infection were observed. The overall objective of this thesis was to address three problematic situations, despite recognised HAART efficacy, especially low-level viremia (LLV) and its relationship with virologic failure, and the impacts of certain antiretrovirals (ARV) on kidney and hepatic functions. The specific objectives were: 1) to study the risk of virologic failure in long-term perspective in undetectable patients under HAART in comparison to patients with persistent LLV; 2) to evaluate the long-term loss of kidney function related to tenofovir (TDF) exposure 3) to evaluate long-term hyperbilirubinemia related to atazanavir (ATV) exposure and other possible determinants. In order to address the three specific objectives, a cohort of patients 2416 living with HIV/AIDS followed in Montreal since July 1977 was used. For the first objective, analyses and results shown an increased risk of virological failure defined as >1000 copies/mL of HIV RNA, for all categories of persistent LLV as soon as 6 months of persistent duration. Persistent LLV of 50-199 copies/mL for 6 months doubled the risk of virologic failure (Hazard ratio (HR)=2,22, Confidence interval (CI) 95%: 1,60-3,09). The results shed new light for the management of patients with LLV, especially for LLV of 50-199 copies/mL, for which no clinical recommendation is currently available due to a lack of data. For the second objective, an increased risk of loss of kidney function of 63% (HR=1.63; 95% CI:1.26–2.10) associated to TDF exposure in comparison to patients taking other ARV was observed. The cumulative eGFR loss directly attribuable to TDF also shown that this loss occured during the first years of exposure. This loss was mild in a long-term perspective. For the third objective, it has been shown that the cumulative incidence of hyperbilirubinemia in ATV users was very high and that regression was possible if ATV exposure was ended. Long-term hyperbilirubinemia related to ATV use was not associated with adverse health outcome. Overall, this thesis allowed a better understanding of these three problematics currently debated in scientific literature and shed new lights on management of HIV positive patients under therapy.
