The effect of tenofovir on renal function and immunological response in HIV-positive patients in LesothoMugomeri, Eltony January 2013 (has links)
Thesis (M. Tech. (Biomedical technology)) - Central University of technology, Free State, 2013 / INTRODUCTION: The renal effects of Tenofovir Disoproxil Fumarate (TDF) and antiretroviral treatment (ART) outcomes remain under-reported in African settings. The study sought to assess immunological outcomes and to compare renal function outcomes between patients exposed to TDF and unexposed patient group.
METHODS: Phase 1 of the study was a retrospective case control analysis of serum creatinine data for 312 ART naïve adult patients exposed to TDF and 173 unexposed patients enrolled on ART between Dec 2006 and Jan 2011 at Roma Health Service Area in Lesotho. Sub-optimal renal function outcomes were serum creatinine clearance values <50 ml/min calculated using the Cockcroft-Gault equation. Phase 2 was based on re-sampling of the study population and analysis of CD4 counts of 516 adult naïve HIV-positive patients. Univariate logistic regression (p<0.1) and multivariate analyses (p<0.05) were performed using STATA® version 11 software.
RESULTS: Overall, 153 (31.5%) patients had moderate baseline (30-60 ml/min) renal insufficiency. Renal function improved by +2 ml/min at 24 months. Almost 18% (n=312) of the patients on TDF were erroneously put on TDF. The use of TDF was a marginally significant factor (p=0.054) associated with CrCl<50 ml/min outcomes in univariate analysis but was insignificant (p=0.122) in multivariate analysis. Female gender (p=0.016), high blood pressure (p=0.009), ages over 60 (p=0.004), and underweight (p<0.001) were significantly associated with CrCl<50 ml/min outcomes. The proportion of patients who developed immunological failure in this study was low (6.8%, n=516). The mean CD4 count increased significantly after treatment (p<0.001). Baseline CD4 count below 50 cells/mm3 (p=0.049) and male gender (p=0.005) were significantly associated with sub-optimal immunological outcomes.
CONCLUSIONS: TDF is a weak contributing factor associated with renal impairment outcomes compared to other variables such as hypertension, older age, underweight and female gender. More research on long term effects of TDF is recommended. Baseline renal function screening should be improved to minimise leakages of patients contraindicated of TDF. Although the patients’ immunological status generally improved, males and patients with low baseline CD4 counts should be monitored closely while on ART.

Assessment of knowledge, attitudes and utilisation of HIV post-exposure prophylaxis among adults, Roma, LesothoLebona, Maselobe Anna 11 1900 (has links)
As the Human Immunodeficiency Virus (HIV) prevalence rises, uninfected Basotho face an increased risk of exposure. This necessitates strengthening of strategies that prevent exposure, and where exposure has occurred, measures that prevent infection. One such measure is Human Immunodeficiency Virus (HIV) Post-Exposure Prophylaxis (PEP). Awareness and knowledge of HIV PEP is therefore of paramount importance. The purpose of this study was to assess knowledge, attitudes and utilisation of HIV PEP among adults in Roma, Lesotho. A quantitative cross-sectional study was conducted among 96 adult outpatients at St Joseph’s Hospital. Data were collected by means of structured questionnaire and analysed using SPSS version 23.0. Results were presented using charts and tables. Awareness of HIV PEP among the respondents was found to be very low and for most respondents’ knowledge of HIV PEP was either non-existent or very poor. Utilisation was also found to be very low. Attitudes towards HIV PEP were, however, found to be favourable. More studies should be conducted throughout the country to further explore Basotho’s knowledge, attitude and use of HIV PEP. / Health Studies / M.A. (Nursing Science)

An investigation into the stigmatization of HIV-positive clients at clinics in the Leribe districtEkeji, Immaculata Nwogo 06 1900 (has links)
A quantitative approach was used to investigate the stigmatization of HIV positive
clients in the Leribe District of Lesotho. The study population included 5200 HIV positive
patients who enrolled for ARV in government clinics. A randomly selected sample of
520 clients responded through a questionnaire and interviews. The statistical package
(STATA version 9) was used to analyze data. The objectives of the study were to
explore the type and level of stigmatization of HIV-positive clients and to describe ways
in which health workers in the PHC can reduce the stigmatization of HIV-positive clients
at the clinics. The findings revealed that types of stigmatization included separation,
isolation, labeling and discrimination. Ways to reduce the stigma within a community
based primary health care facility included educating people living with HIV on how to
protect themselves from multiple infection, providing effective counselling to clients and
families maintaining confidentiality, and using change strategies to change attitudes of
health care providers. The integration of HIV-related activities is a strong
recommendation and the importance of the consistent availability of ARV treatment was
emphasized. / Public Health / M.A. (Public Health)
