Determinants of infants Human Immunodeficiency Virus positivity rates in Greater Letaba Municipality, Limpopo Province, South Africa

Mkhari, Lillian Bridgette Tshameleni January 2021 (has links)
Thesis (MPH.) -- University of Limpopo, 2021 / Introduction: HIV/AIDS remains a disease of public health importance and mother-to-child transmission (MTCT) is one of the major problems. Sub-Saharan Africa is the most severely affected region, accounting for more than 90 percent of paediatric HIV infections. Most of these infections occurred during pregnancy, delivery or breastfeeding making the prevention of mother-to-child transmission (PMTCT) a public health priority. Over the last few years, efforts have been made in Sub-Saharan countries to improve PMTCT and the success of prevention of mother‐to‐child transmission of HIV (PMTCT) is dependent upon high retention of mother‐infant pairs within the PMTCT cascade. Assessing the risk factors for MTCT will help to decrease child morbidity and mortality and strengthen PMTCT programs as there is dearth of evidence regarding factors determining MTCT HIV infection to infants born to HIV positive mothers. The purpose of this study was to investigate the determinants for the human Immunodeficiency Virus positivity rates in the Greater Letaba Municipality. The study objectives were to describe the demographic characteristics of mothers and babies who tested polymerase chain reaction test (PCR)-positive in the Greater Letaba Municipality during the two-year period from 2015 to 2016, in order to determine maternal and neonatal factors associated with high positive PCR; and to determine health system-related factors associated with a high positive PCR result. Methodology The current study followed a quantitative approach in which convenient and purposive sampling was used, focusing on records of infants born from HIV-positive women in all clinics at Greater Letaba Municipality were reviewed. All records of infants who were tested for HIV and the PCR results were positive from birth up to 12 months of age were retrospectively reviewed and for the health care workers, all nurses working as managers of a clinic were interviewed. The Statistical Package for the Social Sciences (SPSS) version 23 computer software and Stata 15 was used. for comparison of categorical variables was done using a Chi-Squared test, whereas continuous variables were compared using a t-test and P-value of <0.05 was considered significant. To determine maternal and neonatal factors associated with high positive PCR, Factor analysis was used with rotated factor loadings done using the Varimax method. Results: A total of 107 records were retrieved and audited. Fisher’s exact test was used to determine the relationship between selected variables, where p<0.05 was set as level of significance. The findings reveal that the number of infants exposed to HIV during pregnancy has steadily increased. The current study further indicates that health system factors such as unskilled or untrained NIM-ART nurses in the facilities is a contributory factor to infant’s positivity rate in Greater Letaba hospital. Equal proportions of both male and female babies were found to be PCR positive at 6 weeks. The study further revealed that the highest proportion of the mothers who gave birth to PCR positive babies for the reporting period were married mothers, in the age group 25-29 years (46.1%). The second largest proportion of mothers who gave birth to PCR positive babies were single mothers in the age group 25-29 years (38.4%). The results show that high PCR positivity can be attributed to about 5 main Factors namely: maternal antenatal history (22% contribution to total variance), maternal HIV care history (18% contribution to total variance), measures of adherence to treatment (17% contribution to total variance), maternal exposure to HIV (14% contribution to total variance) and lastly the ART regimen (12% contribution to total variance). Conclusion: The study findings revealed that there is still vertical transmission of HIV to infants and the prevalence of HIV among infants born from seropositive mothers despite the availability of the latest Prevention of Mother to Child Transmission (PMTCT) Guidelines in all health care facilities. Even though transmission is reduced to the meaningful number (< 5%), there are still appropriate measures that should be taken to reduce the transmission of HIV from mothers to infants. The delayed diagnosis, adherence to ART by mothers, infant ARV prophylaxis at birth and feeding practices contributed the vertical transmission of HIV to infants. Strengthening of the PMTCT of HIV programme, increasing antenatal HIV screening and linking it to care and treatment of HIV positive mothers to obtain zero infant HIV prevalence in the region. Infant prophylaxis and maternal PMTCT interventions should be provided to all exposed infants and mothers based on the guidelines by the health institutions. Nurse-initiated management of antiretroviral treatment (NIM-ART) training of professional nurses is being offered by the Department of Health in South Africa, but it does not yield positive results as far as the PMTCT is concerned. This may be due to shortage of staff, especially trained professional nurses (PN), as well as the workload. Key concepts: Infant and Human immune deficiency virus

An evaluation of postnatal care rendered to HIV positive women and their infants

Dlamini, Bongani Robert 01 February 2013 (has links)
The purpose of this study was to evaluate care rendered to HIV positive women and their infants during the first six weeks of postpartum. Quantitative, descriptive, cross sectional and analytic study was conducted to investigate postnatal care services provided to HIV positive mothers. Data collection was done using structured questionnaires. 372 respondents participated in the study. Descriptive data analysis was used; Epi info version 3.5.2 software was used. The study highlighted that the quality of PNC was compromised, in all levels including the critical immediate postnatal care, 3-14 days and 6 weeks postnatal care services. All health facilities that were involved in the study had the basic resources to render quality postnatal care. Negative attitudes of staff and long waiting time (16.7%), were the most deterrents to postnatal care. / Health Studies / M.A. (Health Studies)

Contributory factors for HIV upsurge among children aged three to eighteen months in Mangaung, Free State province

Phakisi, Selloane 07 1900 (has links)
First eleven leaves not numbered / The purpose of this study was to identify, explore and describe the potential contributing factors of the upsurge of HIV among children aged three to eighteen months in the Mangaung Metropolitan area of the Free State Province in South Africa. The study was conducted at five primary healthcare facilities and one hospital in the Mangaung metropolitan municipality of the Free State Province with sixty randomly selected mothers of children testing HIV-positive for the first time between the ages of three and eighteen months. The convergent mixed-methods research design was opted for, according to which both qualitative and quantitative data were collected at the same health facilities selected by means of cluster sampling. The review of medical records, unstructured interviews, and structured questionnaires were used for qualitative and quantitative data collection, while random cluster sampling was used for participant selection. Thematic data analysis was applied for the interpretation of recurrent patterns of qualitative and quantitative data. The study results revealed that mothers were well-informed about the prevention of mother-to-child-transmission. The main factors that contributed to more children testing HIV positive after the routine tests were conducted at ten weeks included non-adherence factors to PMTCT prescripts mainly by mothers, such as: babies were not brought to the clinics for testing and immunisations at ten weeks, and that mothers acquired HIV infection during the breastfeeding period. Some other potential contributing factors were late antenatal booking which lead to the delay in initiation of antiretroviral treatment, nonadherence to antiretroviral therapy during pregnancy, and mixed feeding. The themes that emerged from the qualitative data were psychological factors, emotional factors, socioeconomic factors, missed opportunities, risky behaviour, as well as women disempowerment; while some mothers were left with unanswered questions. The results of the qualitative part complemented the quantitative findings as they uncovered the factors that led to the deviation from the PMTCT prescripts by the mothers. The study’s recommendations include PMTCT psychological assessment and counselling; partner and community involvement; women empowerment; and that couple testing at antenatal and postnatal clinics should be a national policy subjected to protracted monitoring and evaluation processes. / Health Studies / D.

Innate immune mechanisms in limiting HIV-1 pathogenesis among South African adults and mother-infant pairs.

Ndlovu, Bongiwe Goodness. 11 November 2013 (has links)
This study was conducted to investigate the role of natural killer cell surface receptors, KIRs and their cognate HLA ligands in preventing HIV-1 acquisition and disease progression in HIV-1 exposed infants. Using DBS stored for 8 years from 21 pregnant South African women we evaluated 3 methods of gDNA extraction with and without whole genome amplification (WGA) to characterize immune-related genes: IL-10, KIR and HLA class I. However, IL-10 SNP typing was only for testing the quality of gDNA. QIAamp DNA mini kit yielded the highest gDNA quality (p<0.05; Wilcoxon Signed Rank Test) with sufficient yield for subsequent analyses. In contrast, WGA was not reliable for SSP-PCR analysis of KIR2DL1, KIR2DS1, KIR2DL5, and KIR2DL3 or high resolution HLA genotyping using a sequence-based approach. A cohort of 370 infants; 124 HIV-1 perinatally infected, 120 exposed uninfected and 126 unexposed healthy infants was used for KIR and HLA genotyping. After adjustment for viral load and multiple comparisons, the frequency of HLA-Cw*04:01 allele was likely to be associated with susceptibility to mother-to-child acquisition of HIV-1 in exposed infected (EI) infants (p=0.05; Logistic Regression analysis). HLA-A*23:01 was likely to be associated with decreased CD4 T lymphocyte count in HIV-1 infected infants (p=0.01; ANOVA), whereas HLA-B*81 tended to be associated with higher CD4 T lymphocyte count (p=0.04, ANOVA). We speculate that HLA-Cw*04:01 interacts with KIR2DL1 and inhibit NK cell responses which predispose the infants to HIV-1 infection. KIR2DS1 and KIR2DL5 were both associated with faster HIV-1 disease progression. Identified protective HLA-class I alleles could be used to present viral epitopes to either NK cells via KIRs or CTLs and enhance immune activation which may promote resistance to HIV-1 infection. / Thesis (M.Med.Sc.)-University of KwaZulu-Natal, Durban, 2012.

An assessment of the knowledge, attitudes and practices of caregivers of HIV positive children on treatment in Pretoria, South Africa : a case study of out-patients in Kalafong Hospital, Pretoria

Ofunne, Ifeanyichukwu 04 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: This study examines the level of HIV and AIDS knowledge, attitudes, as well as practices amongst caregivers of HIV infected children in Pretoria, using Kalafong hospital as a case study. The study uses a questionnaire as survey instrument. A total of 30 respondents participated in the study, which took place in October of 2013. The respondents were selected via simple random sampling and the results were analyzed. The results showed a remarkably high level of HIV and AIDS knowledge amongst the respondents, from which it was evident, that: A significant number of caregivers were aware of and able to take care of existing medical conditions arising from HIV in children. Most of the home-based care of children living with HIV was carried out by women in a very disproportionate ratio to men. In this regard, the study offers a range of suggestions and recommendations as well as existing best practices, such as the UNAIDS booklet on caregiving within the context of HIV and AIDS. The study was undertaken with the realization that generalizations cannot be made through extrapolation to the larger society because of limitations, such as the sample size of this study. / AFRIKAANSE OPSOMMING:Hierdie studie ondersoek die vlak van MIV/VIGS kennis, houdings teenoor dieselfde, sowel as praktyke onder versorgers van MIV-besmette kinders in Pretoria, met behulp van Kalafonghospitaal as 'n gevallestudie. Die studie maak gebruik van 'n vraelys as opname instrument. 'n Totaal van 30 respondente het deelgeneem aan die studie, wat in Oktober 2013 plaasgevind het. Die respondente is gekies deur 'n eenvoudige ewekansige steekproefneming en die resultate is ontleed. Die resultate toon 'n merkwaardig hoë vlak van MIV en VIGS kennis onder die respondente. Hierdie kennis, houdings en praktyke opgedoen was voldoende om daarop te let: • 'n beduidende aantal van die versorgers is bewus van en in staat om bestaande toestande in MIV-sorg in kinders te versorg. • Die meeste van die tuisversorging van kinders wat met MIV leef is uitgevoer deur vroue in 'n baie oneweredige verhouding met mans. In hierdie verband bied die studie 'n verskeidenheid van voorstelle en aanbevelings sowel as die bestaande beste praktyke soos die UNAIDS boekie oor versorging binne die konteks van MIV en VIGS. Die studie is gedoen onder die besef dat veralgemenings nie gemaak kan word deur ekstrapolasie na die groter samelewing nie, as gevolg van beperkings soos die monster grootte van hierdie studie

The experiences of teachers regarding provision of care and support to school children on antiretroviral therapy in Swaziland

Nxumalo, Futhi Antinate 01 1900 (has links)
The aim of the study was to gain in-depth understanding of teachers ’experiences with regard to the provision of care and support to school children on antiretroviral therapy in Swaziland in order to recommend approaches for enhancing support and care offered to children on ART by teachers. The study explored the experiences of teachers providing care and support to school children on antiretroviral therapy in Swaziland. The study used interpretative phenomenological analysis design. The study population was primary schools teachers in Swaziland. Data were collected through individual semi structured interviews from 16 purposively selected teachers. Data were analysed using interpretative phenomenological analysis framework for data analysis. Three superordinate themes emerged from data analysis namely: (1) Increased responsibility, (2) inadequate support and (3) psychological impact. The increased responsibility is related to ensuring that children who are on antiretroviral therapy have eaten before taking antiretroviral treatments, are properly dressed, receive proper education and health care and protected from bullying and social exclusion. Inadequate support for teachers makes caring for the learners very challenging. The psychological impact of caring for these learners are sense of accomplishment, demotivation; helplessness and emotional pain. Recommendations are made to ensure support for teachers rendering care and support to children on antiretroviral therapy. / M.A. (Nursing Science) / Health Studies

The participation of children in HIV/AIDS clinicals trials : ethical and legal considerations

Mujinga, Sandrine Mutumba 06 1900 (has links)
This dissertation examines the legal position relating to the participation of children in research, especially in HIV preventive clinical research in South Africa. HIV/AIDS presents a real threat to humanity and particularly to the welfare of children. The participation of children in this type of trials is therefore vital. Children, as vulnerable participants, must also be protected from harm resulting from research. The study also considers the nature of HIV preventive clinical research, pointing to the inconsistencies in the legislation governing children’s participation in HIV preventive vaccine trials. The dissertation concludes that the question of the participation of children in HIV preventive clinical research poses many challenges, as the position in the South African law and relevant ethical guidelines are inconsistent and contradictory. The study recommends in the final instance that the relevant statutory provisions and ethical guidelines be harmonised in order to clear up the inconsistencies. / Jurisprudence / LL.M.

Factors related to male participation in prevention of mother-to-child transmission of human immunodeficiency virus in three public hospitals in Addis Ababa, Ethiopia

Daniel Kinde Getu 10 1900 (has links)
This study aimed at assessing factors related to male participation in PMTCT in three public hospitals in Addis Ababa, Ethiopia. A quantitative, descriptive correlational design was used to assess correlation between male participation and socio-demographics, knowledge and awareness in HIV/PMTCT, socio-cultural belief, programmatic factors and reported risk. Male partners (n=216) were interviewed and reviews of HIV counselling and testing (HCT) acceptance formats were made. The major findings were 54.5% (n=156) males reported receiving HCT during their visit to partner’s antenatal care. Some 71.5 % (n=677) of women were accompanied to labour wards by male partners; 86.5% (n=208) of males accepted intra-partum HCT; 55.1% (n=216) scored above the mean score (10) on a 15-point scale for male participation. Male participation in PMTCT was found to have a statistically significant but weak correlation with educational level (r=0.193), income (r=0.167), PMTCT knowledge and awareness (r=0.172), socio-cultural belief (r=-0.164) and reported risk (r=-0.23). / Health Studies / M.A. (Public Health)

Development of nutrition education material for caregivers of immune compromised children in children's homes in the Durban area

Grobbelaar, Hendrina Helena January 2011 (has links)
Dissertation submitted in fulfillment of the requirements for the Degree of Magister Technologiae: Consumer Science Food and Nutrition, Durban University of Technology, 2011. / Nutrition plays a fundamental role in the care and support of people living with the Human Immunodeficiency Virus (HIV) and children in particular are affected by HIV and the Acquired Immunodeficiency Syndrome (AIDS) epidemic in Africa in various ways. The epidemic puts children at risk physically, psychologically and economically. Children are indirectly affected by HIV and AIDS when the epidemic has a negative impact on their communities and the services these communities provide. Undernutrition is a major problem in HIV-positive children in South Africa with severe malnutrition as a common finding in HIV-positive children. HIV contributes to an increased incidence and severity of undernutrition and micronutrient deficiency. Low serum levels of vitamins A, E, B6, B12 and C, betacarotene, selenium, zinc, copper and iron deficiencies are frequently documented during all stages of HIV-infection. Malnutrition in turn further weakens the immune system which increases the susceptibility to infections and the duration and the severity of infections. Thus, the immune response is less effective and less vigorous when an individual is undernourished. Although guidelines exist for the treatment and management of HIV-infected children, it is clear from the literature that exceptional measures are needed to ensure the health and well-being of the children are met. Furthermore, residential care should not only be considered as a last resort for children’s care, but also as an intervention that requires more than merely addressing children’s basic physical needs. Nutrition education has been utilised globally and in South Africa to address nutrition related problems. The main purpose of nutrition education is to provide individuals with adequate and accurate information, skills and motivation to buy, produce and consume the correct foods to stay healthy and lead an active life. Aim The purpose of this study was to develop reliable and valid nutrition education material for the child care workers (CCWs) of Immune Compromised children vi resident in Children’s Homes in the Durban area in order to maintain the child’s immune system and to optimise their quality of life. Methodology The FAO framework used for planning, implementing and evaluating a nutrition education programme was followed to develop the nutrition education material in this study. Phase I included a situational analysis of the children homes involved. The residential care settings that participated in this study included three Children’s Homes in Durban. The total purposive sample included: boys (5–19 years) n = 112, girls (5–19 years) n = 38 and CCWs n = 40. The sample of HIV-positive children included boys (5–19 years) n = 3 and girls (5– 19 years) n = 6. The physical measurements obtained for this study to determine nutritional status were weight and height. The anthropometric measurements were captured and analysed by the researcher using the World Health Organisation’s AnthroPlus version 1.0.2. Statistical software. The following indices were included: height-for-age (stunting), weight-for-age (underweight) and BMI-for-age (overweight and wasting). The WHO growth standards for school-aged children and adolescents were used to compare the anthropometric indicators. Dietary intake measurements were done by analysing the cycle menus by means of the Food Finder® Version 3 computer software program and comparing the results with the Dietary Reference Intakes (DRIs), specifically the EAR and AI where the EAR were not available. The data were analysed to determine the adequacy of energy and nutrient intake. Average portion sizes were established by the plate waste studies method as well as observation of practices, interviews with the central buyer and focus group discussions with the CCWs. Nutrition knowledge of the CCWs was determined by a self-administered questionnaire developed and tested for reliability and validity. The problems identified in Phase I through the implementation of the questionnaires and other methods directed the design of messages in Phase II. Once suitable media was selected, nutrition education material was developed based on existing guidelines pertaining to HIV and AIDS. The material developed was then tested for reliability and validity before it was produced. vii Results The anthropometric measurements indicated that the majority of the HIV-negative boys and girls were of normal height-for-age and weight-for-age. The results also showed that possible risk of overweight and overweight were more prevalent in girls whereas underweight was more prevalent in boys. Furthermore, the results indicated that a third (33.0%) of the HIV-positive children were stunted and 16.7% was severely stunted. Findings of the menu analysis indicated that both girls and boys consumed three times more carbohydrates than the recommended intake. The DRIs for girls and boys were met for energy and protein in all the age groups except boys aged 14-18 years did not meet the DRI for energy. However, the comparison of the actual intake of the macro nutrients with the WHO guidelines indicated that the protein (10.78%) and carbohydrate (58.07%) is within the recommendations of 10- 15% and 55–75% respectively. This comparison also showed that the total fat intake of 31.15% was above the recommended intake of 15-30%. None of the age groups met the DRIs for fibre. The comparison of the intake with the WHO guidelines also indicated that the total dietary fibre intake was only 19.67g/day and not 27–40g/day. The actual fruit and vegetable intake was a mere 68.64g/day instead of 400g/day as recommended. None of the groups met the DRIs for calcium and iodine. The results clearly showed that micro nutrient inadequacies were more prevalent in the dietary intake of age groups 9-13 and 14-18 years in both girls and boys. Inadequate intake of magnesium, vitamin A, vitamin C, riboflavin, niacin, vitamin B6, pantothenate, biotin, vitamin E and vitamin K were evident in the age group 14-18 year. Overall, it is evident from the results on nutrition knowledge that although the respondents’ knowledge was fair on general nutrition guidelines, the results of the nutrition knowledge questionnaire indicated that knowledge on the importance of a variety in the diet is lacking. The CCWs displayed a very poor knowledge of the recommended number of fruit and vegetable portions per day as well as correct serving sizes of vegetable portions. A very poor knowledge also existed regarding the role of healthy eating in maintaining and supporting the immune system and a limited knowledge on correct hygiene practices was noted. The fridge magnets developed included five messages relating to nutrition and four messages relating to food safety and hygiene. viii Conclusion This study established that malnutrition is apparent in the children’s homes and that there were many gaps in the nutrition knowledge of the CCWs. These gaps included the role of good nutrition in the support and maintenance of the immune system and the importance of adequate intake of fruit and vegetables daily. The NEM developed in this study will address these gaps.
