There are about 3576 clinical studies being (or have been) conducted in South Africa. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
human immunodeficiency virus / acquired immunodeficiency syndrome (HIV/AIDS) is the second leading cause of death in Africa. Adolescents living with HIV (ALWH) are at increased risk for HIV-related morbidity and mortality due to poor retention in HIV care and suboptimal antiretroviral therapy (ART) adherence. Despite having the world's largest population of Adolescents living with HIV (ALWH) (15-24 years, n=870,000), only 14% of South African ALWH are on ART, 12% are retained in HIV care 1-2 years after ART initiation, and 10% are virally suppressed. During treatment interruption, the effects of ART quickly reverse, increasing transmission risk, treatment resistance, and potentially fatal complications. Unless their treatment retention and adherence improves, ALWH will continue to transmit the virus to their sexual partners and die prematurely. While social support is often viewed as a bridge that joins ALWH to key resources within their environments, little is known about which types of social support are most impactful and from whom within their network, particularly among ALWH in endemic countries. Moreover, many South African ALWH lack social support from key social network members due to lack of HIV status disclosure, increasing their risk for poorer HIV-related outcomes when compare to their disclosed peers. Social network interventions (i.e., those that leverage the resources within one's network to improve behaviors and outcomes) that meet the needs of both ALWH who are disclosed and non-disclosed are needed, but lacking. Such inventions have the potential to facilitate appraisal support, during which ALWH receive targeted assistance with identifying appropriate and trustworthy people in their lives. More broadly, there exists a lack empirically supported interventions aimed at improving retention in HIV care and ART adherence for ALWH in low-middle income countries. This proposal follows the multiphase optimization strategy (MOST), a comprehensive framework for optimizing and evaluating multicomponent behavioral interventions.
A randomised, double-blind, cross-over study to assess the analgesic effect of methoxyflurane at moderate high altitudes in a wilderness field setting. Phase IV, randomised, double-blind, cross-over clinical trial to evaluate the analgesic effect of methoxyflurane at moderate high altitudes in a wilderness field setting, in 24 healthy volunteers
The purpose of the study is to prospectively assess the use of a modified tracheal balloon dilator in children (<13 years old) with subglottic or tracheal stenosis. The hypothesis is that the device will effectively dilate the stenotic segment, whilst maintaining oxygenation (if applicable). The primary aim is to measure the stenosis prior to, and after dilatation; using diameter and the modified Myer-Cotton grading system. Secondary aims include assessment of stenosis at six-week follow-up and monitoring arterial oxygenation nadir (using peripheral plethysmography) during the procedure.
Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disease that occurs most commonly during early infancy and childhood. It is frequently associated with abnormalities in skin barrier function, allergen sensitization and recurrent skin infections. AD is a major public health problem worldwide, with prevalence in children of 10-20% and 2-5% of the general population. The skin of AD patients is susceptible to colonization and infection with Staphylococcus aureus (SA )which contribute significantly to the severity of the clinical manifestations of eczema, triggering a vicious cycle. Fusidic Acid (FA) cream is a topical antibiotic widely used in the treatment of skin and soft tissue infections and infected atopic dermatitis. However in recent years, the emergence of drug-resistant organisms, e.g. Methicillin- resistant Staphylococcus aureus (MRSA) has led to scrutiny of antibiotic use. Prolonged use of topical FA has been linked with emergence of FA-resistant Staphylococcus aureus (FRSA) . Fusidic acid is a natural antibiotic, extracted from cultures of Fusidium coccineum, which has a powerful antibacterial action. Topical use of Fusidic acid is fully in line with therapeutic strategies that recommend the use of an antibiotic with the narrowest activity spectrum to minimize the risk of resistance. In AD with infected lesions, combined treatment with antibiotic and steroid demonstrates greater efficacy over the use of steroid. Trial Design: A three-center, double blind, randomized ,phase II , parallel group, efficacy trial. Type of Intervention: A triple compounded cream containing a topical antibiotic , topical steroid and moisturizer. Type of control: Active control containing a double compounded cream comprising a topical steroid and moisturizer . Study population and Setting: A sample of 78 subjects will be recruited from Red Cross Children's Hospital , Nelson Mandela Academic Hospital and King Edward Hospital Estimated duration of trial: 12 months. Duration of participation: Each subject will participate in the trial for a maximum of 140 days. Primary endpoint: reduction in SCORAD scores; frequency of clinical flares for AD and improvement in the quality of life at 140 days. The benefit of this trial is that it provides a simple and effective approach to the management of atopic eczema.
This is a case-control study embedded in a surveillance system to determine the effectiveness of antenatal maternal influenza vaccination against laboratory-confirmed influenza-associated hospitalised illness in infants <6 months of age.
The purpose of this study is to determine whether vitamin D supplements given to children aged 1 month to 5 years, hospitalized with acute lower respiratory tract infection will improve symptoms and reduce the duration of hospitalization.
The aim of this randomized double-blind placebo controlled study is to assess whether vitamin D supplementation will improve control in South African children with persistent asthma at an academic hospital. The following hypotheses will be tested: Vitamin D significantly and directly correlates with poor control of persistent asthma; Daily vitamin D supplementation for six months will result in improved control of persistent asthma compared to a placebo. It is intended to enroll 100 children between the ages of 6 to 12 years with persistent asthma on inhaled therapy. The sample size calculations are based on the hypothesis that vitamin D supplementation will result in a 25% improvement in asthma symptoms as measured by the Asthma Treatment Assessment Questionnaire (ATAQ) and peak flow readings. The children will be randomized into one of two groups; one group will be given 1200 IU of vitamin and the other a placebo. The vitamin D or placebo will be given in the morning daily to each child for six months. The children will be assessed monthly by the study physician, to evaluate for signs of poor asthma control e.g. persistent cough and recurrent wheezing. The heights and weights and peak expiratory flow meter readings will also be obtained monthly for six months. Blood samples will be taken for Vitamin D levels, calcium, phosphorus levels at baseline, third month and at the end of the study. All enrolled children will be required to produce their tablet containers for pill counting on a monthly basis to ensure adherence.
This study will use the licensed HPV vaccine, Gardasil, as a surrogate for an HIV vaccine, in order to explore some of the ethico-legal,psycho-social and logistical challenges involved in running an HIV vaccine trial in adolescents.
