Globally an estimated 33.4 million people were living with HIV/AIDS by 2008 (UNAIDS, 2009a:7). One of the main challenges facing the Republic of South Africa (RSA) today is the HIV/AIDS epidemic (NSP, 2007:17). By mid-year 2011 an estimated 5.38 million people (10.6% of the total population) were living with HIV/AIDS in the RSA (Statistics South Africa, 2011:2). Currently South Africa has the largest number of people enrolled in the Highly Active Antiretroviral Treatment programme (HAART) in the world (WHO, 2008:59). The objective of this study was to determine retrospectively the medicine treatment patterns of HAART at a district hospital in the North West Province of South Africa. The study was conducted at Thusong hospital in the Ditsobotla sub-district of the North West Province of South Africa. A non-experimental, retrospective, cross-sectional, drug utilisation research methodology was used to obtain the data. The target population included patients of all ages who visited Thusong hospital pharmacy during the data collection period, which commenced on 01 February 2012 and ended on 31 March 2012. The data of three hundred and ninety nine (N=399) adult and one hundred and sixty one (N=161) paediatric patients on HAART were used. The adult female patients accounted for almost 70% (n=276, 69.17%) and the adult male patients for only 30% (n=123, 30.83%). The male paediatric patients represented just over 60% (n=97, 60.25%), whereas the female paediatric patients comprised less than 40% (n=64, 39.75%). The majority of adult patients were unmarried (n=323, 80.95%) and this group of patients were also the youngest group (μ=36.38 ± 8.98 years) on ARV treatment. Almost 86% (85.96%, n=343) of adult patients were registered as unemployed. Ninety two (n=92, 23.06%) adult patients and fifty eight (n=58, 36.03%) paediatric patients defaulted treatment during the defined period. The investigation into the adult medicine treatment patterns revealed that more than half (52.38%, n=209) of all the adult patients were receiving regimen 1atn (EFV, TDF and 3TC), followed by 20.80% (n=83) on regimen 1a (EFV, D4T and 3TC). Most paediatric patients (n=73, 45.34%) were on regimen P1c (EFV, D4T and 3TC) and the second most (n=45, 27.95%) were on regimen P1a (D4T, 3TC and LPV/r). The average weight of adult female patients was 57.18kg (± 15.78kg) and the average adult male patient weighed 55.87kg (± 10.17kg) on initiation of HAART. The average adult male patient was initiated on HAART with a CD4 count of 130cells/mm3 (± 99.45cells/mm3), while for adult female patients it was 160cells/mm3 (± 96.52cells/mm3). The average male child was initiated with a CD4 count of 509.1cells/mm3 and the average female paediatric patient with 477.3cells/mm3. The average viral load for adult female patients on initiation of HAART was 103046copies/mm3 (± 189146copies/mm3) and for adult male patients it was 416600copies/mm3 (± 439746copies/mm3). The difference between the viral load of adult female and male patients were described as statistically (p=0.0006) and practically (d=0.713) significant. The average viral load for female paediatric patients on initiation of HAART was 242207copies/mm3 (± 709133copies/mm3) and for male paediatric patients it was 329734copies/mm3 (± 674532copies/mm3). Adult patients that received HAART at more than 12 consultations revealed an average weight gain of 3.43kg (± 8.11kg) from initiation of treatment. This group also showed an average increase of 214.71cells/mm3 (± 248.24cells/mm3) in CD4 count and an average reduction in viral load of 170944copies/mm3 (± 191854.69copies/mm3) from the day they started HAART up to the last date of receiving treatment. The paediatric patients on treatment for more than 12 consultations showed an average weight gain of 6.56kg (± 3.75kg) from initiation of ARV treatmentup to the last date of receiving treatment. They also showed an average increase in CD4 count of 396.63cells/mm3 (± 594.53cells/mm3) and a very encouraging average decrease of 538369.37copies/mm3 (± 948634.46copies/mm3) in the viral load. / MPham (Pharmacy Practice), North-West University, Potchefstroom Campus, 2014

Background: According to the United Nations AIDS Reference Group (2010) and World Health Organization (2010:2), approximately 33 million people in the world had HIV/AIDS in 2009 of which 2.6 million were children. More than 30 million of these individuals resided in low– and middle–income countries. South–Africa had the highest prevalence of HIV/AIDS in the world with an estimated 5.2 million patients in 2009 (Statistics South Africa, 2010:2). Although the prevalence of human immunodeficiency virus (HIV) infection among children is reported to be high, little is known about other medication administrated concomitantly with their antiretroviral drugs. Objective: The general objective of this study was to investigate possible changes in the medicine prescribing patterns of HIV/AIDS and non–HIV/AIDS children. Methods: A quantitative, retrospective drug utilisation review was performed utilising medicine claims data of a South African pharmacy benefit management company. Data for a four–year period (Jan 1, 2005 to Dec 31, 2008) were analysed. The study population consisted of all children <=12 years divided into those receiving ARVs (designated HIV positive) and those without (designated HIV negative). Descriptive statistics such as average mean, standard deviation, t–test, d–values, and two way frequency tables were used to describe the results. Data were analysed using the Statistical Analysis System ® SAS 9.1 ® programme. Results: The study population (children <= 12 years) represented 16.2% (n = 197 323) of the total population in 2005, 15.4% (n = 193 346) in 2006, 15.6% (n = 142 049) in 2007 and 13.3% (n = 98 939) in 2008. Children with HIV/AIDS represented 0.2% (n = 197 323) of the study population in 2005 and increased to 0.4% (n = 98 939) in 2008, whereas the percentage of children without HIV/AIDS decreased from 99.8% (n = 197 323) in 2005 to 99.6% (n = 98 939) in 2008. The total number of HIV/AIDS children that also received other medication concomitantly with their ARVs increased from 96.5% (n = 402) in 2005 to 97.2% (n = 427) in 2008. Males with HIV/AIDS who used other medication represented 52.6% (n = 388) in 2005 and increased to 53.3% in 2008 while female HIV/AIDS patients represented 47.4% in 2005 and decreased to 46.7% in 2008. Prescriptions containing three ARV items represented 69.5% (n = 2 969) of the total number of prescriptions received by HIV/AIDS patients in 2005 and decreased to 67.7% in 2008. The combination of lamivudine, nevirapine and stavudine were the three products that appeared most frequently on prescriptions for HIV/AIDS children in the age group 0 <= 1 years and 1 <= 5 years from 2005 to 2008. In the age group 5 <= 12 years the combination most frequently prescribed was lamivudine, nevirapine and zidovudine. HIV positive children received 6.2 ± 4.62 prescriptions for other medication (non–ARVs) per year during 2005 compared to HIV negative children with 3.9 ± 3.71 (p < 0.0001, d = 0.5). In 2008 HIV positive children received 6.4 ± 5.02 prescriptions per year compared to HIV negative patients who received 4.36 ± 4.05 prescriptions (p < 0.0001, d = 0.5) in 2008. HIV negative children received more central nervous system items, endocrine items and autacoids than HIV positive children, whereas HIV positive children received more respiratory system agents, dermatological, ear, nose throat and antimicrobials items. Conclusion: The study showed that HIV positive children received significantly more prescriptions for other medication per year compared to their HIV negative counterparts. The top pharmacological groups mostly prescribed to both groups were respiratory agents, antimicrobials, analgesics, dermatological and ear, nose and throat items. / Thesis (M.Pharm.
