RESUMO
Antiretroviral therapy (ART) could curtail the HIV epidemic, but its impact is diminished by low uptake. We developed a peer navigation program to enhance engagement in HIV care, ART adherence, and behavioral prevention. In preparation for a randomized controlled trial, the program was piloted over four months at two primary health clinics in South Africa's North West Province. Newly diagnosed, HIV-positive clients met regularly with navigators to address barriers to care, adherence, and prevention. To assess program acceptability and feasibility and characterize the mechanisms of action, we surveyed 25 clients who completed navigation services and conducted interviews with 10 clients, four navigators, and five clinic providers. Clients expressed near universal approval for the program and were satisfied with the frequency of contact with navigators. HIV stigma emerged as a primary driver of barriers to care. Navigators helped clients overcome feelings of shame through education and by modeling how to live successfully with HIV. They addressed discrimination fears by helping clients disclose to trusted individuals. These actions, in turn, facilitated clients' care engagement, ART adherence, and HIV prevention efforts. The findings suggest peer navigation is a feasible approach with potential to maximize the impact of ART-based HIV treatment and prevention strategies.

We examined current challenges with patient engagement in HIV prevention and care in South Africa by assessing the procedures of eight public health clinics in the North West Province. Procedures consisted of (1) an inventory/audit of the HIV Counseling and Testing, pre-antiretroviral therapy (pre-ART), and antiretroviral therapy (ART) patient registers; (2) extraction of data from a convenience sample of 39 HIV-positive patient files; and (3) 13 key informant interviews with clinic staff to characterize retention and re-engagement practices for patients. Incomplete registers revealed little evidence of follow-up services, particularly for pre-ART patients. The more detailed examination of patient files indicated substantial disparities in the proportion of pre-ART versus ART patients retained in care. Key informant interviews contextualized the data, with providers describing multiple procedures for tracking and ensuring service delivery for ART patients and fewer procedures to retain pre-ART patients. These findings suggest that enhanced strategies are needed for ensuring continued engagement in HIV care, with a particular emphasis on improving the retention of pre-ART patients. The preventive benefits of ART scale-up may not be achieved if improvements are not made in the proportion of earlier-stage HIV-positive patients who are successfully engaged in care.

BACKGROUND: A robust knowledge on the pattern of use of emergency care resources not only serves as an indicator of universal access to care but also provides a basis for quality improvement within the health system. This study was undertaken to describe the pattern of emergency room visits at Brits District Hospital (BDH) in North West province, South Africa. The objectives of this study were to determine the sociodemographic characteristics of emergency department (ED) users and other patterns of ED use. METHODS: This was a cross-sectional descriptive study that was conducted at a district hospital. All patients who reported for emergency care in the ED in 2016 were eligible for the study. Data were extracted and analysed from a systematic sample of 355 clinical notes and hospital administrative records. RESULTS: The age group that visited the ED most frequently (25.3%) was 25-34 years old. A high proportion of the ED users (60%) were self-referred, and only 38% were transported by the emergency medical response services (EMRS). Few (5.6%) presentations were of a non-urgent nature. Trauma-related conditions accounted for the most frequent presentation at the ED (36.5%). CONCLUSION: Although most ED users were self-referred, their clinical presentations were appropriate and underscore the need for policy strategies to reduce the burden of trauma in the catchment populationContribution: The study findings may have an impact on future health policies by providing decision-makers with baseline information on the pattern of use of ED resources, ensuring better resource deployment and greater access to care.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused coronavirus disease 2019 (COVID-19) pandemic with major disruptions globally. Northwest Province Department of Health (NWDoH) in South Africa set up comprehensive epidemiological emergency response plans for preventing, finding, containing and stopping the spread of COVID-19 in accordance with the National Disaster Management Act. Objectives: This After-Action Report (AAR) describes the provincial response to the pandemic from September 2020 to October 2022. Method: The AAR was conducted using the World Health Organization AAR methodology. Focus groups discussed five items: coordination, leadership and governance; epidemiology, surveillance and laboratory; case management and continuity of essential services; risk communication and community engagement and COVID-19 vaccination. Results: The timely establishment and activation of provincial intergovernmental and intersectoral coordinating structures led to effective coordination, resource mobilisation, leadership, decision-making and intervention. The effective communication in the department and other stakeholders resulted in improved surveillance data quality, timelier response and increased ownership of data. Dissemination, training and implementation of case management protocols ensured standardised case management. The multi-channel information dissemination targeting different audiences empowered people with real-time knowledge on the infection and encouraged health-seeking behaviours. Conclusion: The AAR demonstrated the importance of coordinated epidemiological, laboratory and communication response that requires significant public health reserve capacity in peacetime for rapid expansion in an emergency. Contribution: This review contributes to the body of knowledge emerging from the COVID-19 pandemic and provides guidance on enhanced public health response to future emergencies.
RESUMO
BACKGROUND: COVID-19 is an acute respiratory disease. Its morbidity and mortality in patients with comorbidities have been established. This study evaluated the knowledge, attitude and practices regarding COVID-19 of patients with comorbidities attending primary health care services. METHODS: An analytical cross-sectional study was conducted, with data collected from patients using a self-administered questionnaire. Knowledge, attitude and practice scores were calculated. Descriptive and inferential statistical analyses were used, and the level of significance was set at 5%. RESULTS: This study enrolled 469 participants aged 18-84 years, and the majority were women. The mean knowledge score was 7.09 ± 1.73 out of 9, the mean attitude score was 2.33 ± 0.86 out of 3, and the mean practices score was 3.79 ± 0.56 out of 4. There was a positive linear relationship between knowledge and attitude scores and between attitude and practices scores; as one score increased, the other also increased significantly. CONCLUSION: The level of knowledge was good in general, with optimistic attitudes and good practices by the patients. Those aged 70 years and above need special attention because older persons have poorer knowledge of and practices towards COVID-19, which could lead to higher hospitalisation and mortality rates.Contribution: This study found that patients with chronic diseases had good COVID-19 knowledge, attitudes and practices, while interventions targeting patients aged 70 years and above are needed to improve their COVID-19 awareness and practices.

OBJECTIVE: We examine the efficacy of short message service (SMS) and SMS with peer navigation (SMSâ+âPN) in improving linkage to HIV care and initiation of antiretroviral therapy (ART). DESIGN: I-Care was a cluster randomized trial conducted in primary care facilities in North West Province, South Africa. The primary study outcome was retention in HIV care; this analysis includes secondary outcomes: linkage to care and ART initiation. METHODS: Eighteen primary care clinics were randomized to automated SMS ( n â=â7), automated and tailored SMSâ+âPN ( n â=â7), or standard of care (SOC; n â=â4). Recently HIV diagnosed adults ( n â=â752) were recruited from October 2014 to April 2015. Those not previously linked to care ( n â=â352) contributed data to this analysis. Data extracted from clinical records were used to assess the days that elapsed between diagnosis and linkage to care and ART initiation. Cox proportional hazards models and generalized estimating equations were employed to compare outcomes between trial arms, overall and stratified by sex and pregnancy status. RESULTS: Overall, SMS ( n â=â132) and SMSâ+âPN ( n â=â133) participants linked at 1.28 [95% confidence interval (CI): 1.01-1.61] and 1.60 (95% CI: 1.29-1.99) times the rate of SOC participants ( n â=â87), respectively. SMSâ+âPN significantly improved time to ART initiation among non-pregnant women (hazards ratio: 1.68; 95% CI: 1.25-2.25) and men (hazards ratio: 1.83; 95% CI: 1.03-3.26) as compared with SOC. CONCLUSION: Results suggest SMS and peer navigation services significantly reduce time to linkage to HIV care in sub-Saharan Africa and that SMSâ+âPN reduced time to ART initiation among men and non-pregnant women. Both should be considered candidates for integration into national programs. TRIAL REGISTRATION: NCT02417233, registered 12 December 2014; closed to accrual 17 April 2015.

Alcohol and tobacco use may lead to negative treatment outcomes in tuberculosis (TB) patients, and even more so if they are HIV-infected. We developed and tested the feasibility of a complex behavioral intervention (ProLife) delivered by lay health workers (LHWs) to improve treatment outcomes in TB patients who smoke tobacco and/or drink alcohol, at nine clinics in South Africa. The intervention comprised three brief motivational interviewing (MI) sessions augmented with a short message service (SMS) program, targeting as appropriate: tobacco smoking, harmful or hazardous drinking and medication adherence. Patients received SMSs twice a week. We measured recruitment and retention rates and assessed fidelity to the MI technique (MI Treatment Integrity 4.1 tool). Finally, we explored LHWs' and patients' experiences through interviews and semistructured questionnaires, respectively. We screened 137 TB patients and identified 14 smokers, 13 alcohol drinkers, and 18 patients with both behaviors. Participants' mean age was 39.8 years, and 82.2% were men. The fidelity assessments pointed to the LHWs' successful application of key MI skills, but failure to reach MI competency thresholds. Nevertheless, most patients rated the MI sessions as helpful, ascribed positive attributes to their counselors, and reported behavioral changes. SMSs were perceived as reinforcing but difficult language and technical delivery problems were identified as problems. The LHWs' interview responses suggested that they (a) grasped the basic MI spirit but failed to understand specific MI techniques due to insufficient training practice; (b) perceived ProLife as having benefitted the patients (as well as themselves); (c) viewed the SMSs favorably; but (d) considered limited space and privacy at the clinics as key challenges. The ProLife program targeting multiple risk behaviors in TB patients is acceptable but LHW training protocol, and changes in wording and delivery of SMS are necessary to improve the intervention. Trial registration: ISRCTN14213432.
RESUMO
OBJECTIVE: To investigate the effectiveness of a complex behavioural intervention, ProLife, on tuberculosis (TB) treatment success, medication adherence, alcohol use and tobacco smoking. DESIGN: Multicentre, individual, randomised controlled trial where participants were assigned (1:1) to the ProLife intervention or usual care. SETTING: 27 primary care clinics in South Africa. PARTICIPANTS: 574 adults starting treatment for drug-sensitive pulmonary TB who smoked tobacco or reported harmful/hazardous alcohol use. INTERVENTIONS: The intervention, delivered by lay health workers (LHWs), consisted of three brief motivational interviewing (MI) sessions, augmented with short message service (SMS) messages, targeting medication adherence, alcohol use and tobacco smoking. OUTCOME MEASURES: The primary outcome was successful versus unsuccessful TB treatment at 6-9 months, from TB records. Secondary outcomes were biochemically confirmed sustained smoking cessation, reduction in the Alcohol Use Disorder Identification Test (AUDIT) score, improved TB and antiretroviral therapy (ART) adherence and ART initiation, each measured at 3 and 6 months by questionnaires; and cure rates in patients who had bacteriology-confirmed TB at baseline, from TB records. RESULTS: Between 15 November 2018 and 31 August 2019, 574 participants were randomised to receive either the intervention (n=283) or usual care (n=291). TB treatment success rates did not differ significantly between intervention (67.8%) and control (70.1%; OR 0.9, 95% CI 0.64% to 1.27%). There was no evidence of an effect at 3 and 6 months, respectively, on continuous smoking abstinence (OR 0.65, 95% CI 0.37 to 1.14; OR 0.76, 95% CI 0.35 to 1.63), TB medication adherence (OR 1.22, 95% CI 0.52 to 2.87; OR 0.89, 95% CI 0.26 to 3.07), taking ART (OR 0.79, 95% CI 0.38 to 1.65; OR 2.05, 95% CI 0.80 to 5.27) or AUDIT scores (mean score difference 0.55, 95% CI -1.01 to 2.11; -0.04, 95% CI -2.0 to 1.91) and adjusting for baseline values. Cure rates were not significantly higher (OR 1.16, 95% CI 0.83 to 1.63). CONCLUSIONS: Simultaneous targeting of multiple health risk behaviours with MI and SMS using LHWs may not be an effective approach to improve TB outcomes. TRIAL REGISTRATION NUMBER: ISRCTN62728852.

BACKGROUND: Rotavirus is considered to be the most common cause of serious acute dehydrating diarrhea worldwide. However, there is a scarcity of information on rotavirus disease burden in sub-Saharan Africa. METHODS: We conducted prospective, hospital-based surveillance for rotavirus diarrhea among children <5 years of age at the tertiary care Dr. George Mukhari Hospital (DGM) and at the Brits district Hospital (BH) in the Gauteng and North West Provinces in South Africa; we estimated that up to 80% of children <5 years of age in their catchment areas who are hospitalized for diarrhea are admitted to one of these hospitals. RESULTS: At DGM, 2553 children <5 years of age were admitted for diarrhea from January 2003 through December 2005, and 852 children <5 years of age were treated for diarrhea at BH during 2004-2005. We examined stool specimens from 450 children (53%) at BH and from 1870 children (73%) admitted to DGM. An estimated 22.8% (95% confidence interval [CI], 21.2%-24.5%) of the children hospitalized with diarrhea at DGM were rotavirus positive, and the corresponding figure at BH was 18.2% (95% CI, 14.9%-22.1%). Among children <5 years of age admitted to DGM for any reason, an estimated 5.5% (95% CI, 5.1%-6.0%) had rotavirus diarrhea. Our incidence estimates suggest that 1 in 43-62 children in the area is likely to be hospitalized with rotavirus diarrhea by 2 years of age. CONCLUSIONS: Prevention of serious rotavirus illness by vaccination will substantially reduce not only the disease burden among young children but also the case load in South African health care facilities.

INTRODUCTION: Few interventions have demonstrated improved retention in care for people living with HIV (PLHIV) in sub-Saharan Africa. We tested the efficacy of two personal support interventions - one using text messaging (SMS-only) and the second pairing SMS with peer navigation (SMS+PN) - to improve HIV care retention over one year. METHODS: In a cluster randomized control trial (NCT# 02417233) in North West Province, South Africa, we randomized 17 government clinics to three conditions: SMS-only (6), SMS+PN (7) or standard of care (SOC; 4). Participants at SMS-only clinics received appointment reminders, biweekly healthy living messages and twice monthly SMS check-ins. Participants at SMS+PN clinics received SMS appointment reminders and healthy living messages and spoke at least twice monthly with peer navigators (PLHIV receiving care) to address barriers to care. Outcomes were collected through biweekly clinical record extraction and surveys at baseline, six and 12 months. Retention in HIV care over one year was defined as clinic visits every three months for participants on antiretroviral therapy (ART) and CD4 screening every six months for pre-ART participants. We used generalized estimating equations, adjusting for clustering by clinic, to test for differences across conditions. RESULTS: Between October 2014 and April 2015, we enrolled 752 adult clients recently diagnosed with HIV (SOC: 167; SMS-only: 289; SMS+PN: 296). Individuals in the SMS+PN arm had approximately two more clinic visits over a year than those in other arms (p < 0.01) and were more likely to be retained in care over one year than those in SOC clinics (54% vs. 38%; OR: 1.77, CI: 1.02, 3.10). Differences between SMS+PN and SOC conditions remained significant when restricting analyses to the 628 participants on ART (61% vs. 45% retained; OR: 1.78, CI: 1.08, 2.93). The SMS-only intervention did not improve retention relative to SOC (40% vs. 38%, OR: 1.12, CI: 0.63, 1.98). CONCLUSIONS: A combination of SMS appointment reminders with personalized, peer-delivered support proved effective at enhancing retention in HIV care over one year. While some clients may only require appointment reminders, the SMS+PN approach offers increased flexibility and tailored, one-on-one support for patients struggling with more substantive challenges.

Diarrhea caused by infection with rotavirus annually results in an estimated 611,000 deaths among infants and young children <5 years of age worldwide, and these deaths primarily occur in developing countries. Infection with human immunodeficiency virus (HIV) is also common among young children in many developing countries, particularly in sub-Saharan Africa and Asia. The need for a vaccine to reduce the number of deaths caused by rotavirus infection among children in developing countries is substantial, but current rotavirus vaccines comprise live attenuated oral viruses, the behaviors of which are unknown in HIV-infected children. Therefore, we reviewed available data on natural rotavirus infection in HIV-infected children and examined unpublished data on a small group of HIV-infected infants in South Africa who were given a live rotavirus vaccine. Together, these data suggest that vaccination programs against rotavirus infection could include HIV-infected populations. However, studies addressing the safety, reactogenicity, and immunogenicity of rotavirus vaccines in an HIV-infected population are urgently needed.

BACKGROUND: Salmonella enterica, with more than 2500 diverse typhoidal and non-typhoidal serotypes (NTS), are foodborne bacterial pathogens of global public health concern. NTS are the most commonly reported causes of foodborne acute gastroenteritis (AGE). Contaminated food products (meat, poultry, eggs and dairy) have been reported to be a source of more than 95% NTS infections. An outbreak of food poisoning occurred among schoolchildren exposed to food provided by the government-sponsored National School Nutrition Programme (NSNP) at a local public primary day school in North West province, South Africa. An epidemiological, environmental and microbiological investigation was conducted to establish the existence and extent of the outbreak, identify the source(s) and causative agent(s) and institute appropriate control and preventive measures. METHODS: An epidemiological investigation was conducted, including a review of the clinical records of the persons exposed, laboratory testing of the pathological specimens collected, environmental testing of the food samples and food preparation areas. RESULTS: A total of 164 children developed clinical symptoms of AGE following ingestion of processed maize meal, beans and vegetables. Salmonella enterica serovar Heidelberg (S. Heidelberg) was the causative agent for this AGE outbreak in 92.0% of the cases. The median duration of illness was 2 days with a case fatality rate (CFR) of 0.6%. The main food product that was contaminated was samp (processed maize meal) that had been poorly stored and prepared (53.4%). CONCLUSION: A timeously-initiated epidemiological, environmental and microbiological an investigation led to the conclusion that the etiologic agent of this outbreak was S. Heidelberg, and the most probable food vehicle of transmission was cooked samp served to learners within the NSNP.
RESUMO
BACKGROUND: South Africa is among the seven highest tuberculosis (TB) burden countries. Harmful lifestyle behaviours, such as smoking and alcohol, and poor adherence to medication can affect clinical outcomes. Modification of these behaviours is likely to improve TB treatment outcomes and has proven possible using motivational interviewing (MI) techniques or use of short message service (SMS) text messaging. There have been no studies assessing the effect of combined MI and SMS interventions on multiple lifestyle factors and TB treatment outcomes. METHODS: This is a prospective, multicentre, two-arm individual randomised controlled trial looking at the effectiveness and cost-effectiveness of a complex behavioural intervention (the ProLife programme) on improving TB and lifestyle-related outcomes in three provinces of South Africa. The ProLife programme consists of an MI counselling strategy, delivered by lay health workers, augmented with subsequent SMS. We aim to recruit 696 adult participants (aged 18 years and over) with drug-sensitive pulmonary TB who are current smokers and/or report harmful or hazardous alcohol use. Patients will be consecutively enrolled at 27 clinics in three different health districts in South Africa. Participants randomised individually to the intervention arm will receive three MI counselling sessions one month apart. Each MI session will be followed by twice-weekly SMS messages targeting treatment adherence, alcohol use and tobacco smoking, as appropriate. We will assess the effect on TB treatment success, using standard World Health Organization (WHO) treatment outcome definitions (primary outcome), as well as on a range of secondary outcomes including smoking cessation, reduction in alcohol use, and TB medication and anti-retroviral therapy adherence. Secondary outcomes will be measured at the three-month and six-month follow-ups. DISCUSSION: This trial aligns with the WHO agenda of integrating TB care with the care for chronic diseases of lifestyle, such as provision of smoking cessation treatments, and with the use of digital technologies. If the ProLife programme is found to be effective and cost-effective, the programme could have significant implications for TB treatment globally and could be successfully implemented in a wide range of TB treatment settings.

BACKGROUND: In countries with a high burden of HIV, such as South Africa, where the epidemic remains the world's largest, improving early uptake of and consistent adherence to antiretroviral therapy could bring substantial HIV prevention gains. However, patients are not linked to or retained in care at rates needed to curtail the epidemic. Two strategies that have demonstrated a potential to stem losses along the HIV care cascade in the sub-Saharan African context are use of text messaging or short message service (SMS) and peer-navigation services. METHODS/DESIGN: We designed a cluster randomized trial to assess the efficacy of an SMS intervention and a peer-navigation intervention to improve retention in care and treatment, timely linkage to care and treatment, medication adherence, and prevention behaviors in South Africa. Eighteen primary and community healthcare clinics in Rustenburg and Moses Kotane Sub-districts in the North West Province were randomized to one of three conditions: SMS intervention (n = 7), peer navigation intervention (n = 7), or standard of care (n = 4). Approximately 42 participants are being recruited at each clinic, which will result in a target of 750 participants. Eligible participants include patients accessing HIV testing or care in a study clinic, recently diagnosed with HIV, aged 18 years or older, and with access to a cellular telephone where they are willing to receive automated SMS with HIV-related messaging. Data collection includes extraction of visit information from clinical files and participant surveys at baseline, 6 months, and 12 months. Intent-to-treat (ITT) analysis will explore differences between randomization arms and the primary outcome of patient retention in care at 12 months following enrollment. We will also explore secondary outcomes including participants' a) timely linkage to care (within 3 months of HIV diagnosis), b) adherence to treatment based on self-report and clinic's medication dispensation dates, and c) condom-use behaviors. DISCUSSION: The findings will allow us to compare the efficacy of two complementary interventions, one that requires fewer resources to implement (SMS) and one (peer navigation) that offers more flexibility in terms of the patient barriers to care that it can address.

BACKGROUND: Clinical guidelines are systematically developed statements that assist practitioners and patients to make healthcare decisions for specific clinical circumstances. Non-adherence of doctors to guidelines is thought to contribute significantly to poor delivery of clinical care, resulting in poor clinical outcomes. AIM: To investigate adherence of doctors in rural district hospitals to clinical guidelines using the South African Hypertension Guideline 2006 as an example. SETTING: Four district hospitals in Bojanala district of North-West Province, South Africa. METHODS: A cross-sectional study determined adherence practices of doctors from records of patients with established hypertension seen at the four district hospitals. RESULTS: Of the 490 total records documented by 29 doctors, screening for co-morbidity or associated factors was carried out as follows: diabetes mellitus 99.2%, obesity 6.1%, smoking 53.5%, dyslipidaemia 36.9%, abdominal circumference 3.3%; organ damage: eye 0, kidney 82%, heart 43.5%, chronic kidney disease 38.2%, stroke/transient ischaemic attack 15.9%, heart failure 23.5%, advanced retinopathy 0.2%, coronary heart disease 23.7%, peripheral arterial disease 13.9%. Critical tests/measurements were documented in the following proportions: blood pressure 99.8%, weight 85.3%, height 65.7%, body mass index 3.1%, urinalysis 74.5%, lipogram 76.1%, urea/creatinine 80.4%, electrocardiogram 42.9%, blood glucose 100%; risk determination and grading: diagnosis by hypertension severity 19%, low added risk 57.1%, moderate added risk 64.7%, high added risk 89.6%, very high added risk 89.2%. Adherence to therapies was as follows: first-line guideline drugs 69.4%, second line 84.7%, third line 87.8% and fourth-line 89.6%. CONCLUSION: Overall adherence of doctors to treatment guidelines for hypertension was found to be low (51.9%). Low adherence rates were related to age (older doctors) and less clinical experience, and differed with regard to various aspects of the guidelines.

BACKGROUND: Contraception is often necessary in order to plan for children and without it there is a risk of unplanned pregnancies. In the Democratic Republic of Congo, this often results in abortions by untrained persons with resultant morbidity and mortality. AIM: To investigate the factors that influence contraceptive use amongst women of childbearing age in the Vanga health zone. METHODS: Cross-sectional survey using interviewer-administered questionnaires. RESULTS: Of the 384 women recruited, a majority (46.1%) were in the 31-40 year age group;52% had reached primary school and 88% did not have formal employment. One hundred and forty of the participants reported current use of contraception, with 60% of them using modern methods of contraception; 36.1% of them had begun using contraception before the age of 20; and the most common methods were oral contraceptive pills and injection, each accounting for 22.9%. There was variation in the duration of contraceptive use and the main reason for using contraception was to space children. Of the participants, 20.7% had been using contraception for more than two years. Seventy-seven (31.5%) of the women reported they did not use contraception because of a fear of side effects. Forty-four (18%) reported that they are unable to afford contraception, 38 (15.6%) had husbands who disapproved of contraceptive usage, 26 (10.6%) had a fear of infertility, 18 (7.4%) practised a religion that did not allow them to use contraception and 12 of the women (4.9%) did not use contraception because it was unavailable to them. CONCLUSION: Barriers to contraception in our study were fears of side effects and infertility, cost, male partner's objection, unavailability of contraception and religious beliefs.

BACKGROUND: rotavirus and human immunodeficiency virus (HIV) infections are a cause of great public health concern in developing countries. The current study evaluated the safety, reactogenicity, and immunogenicity of RIX4414 vaccine in asymptomatic or mildly symptomatic (clinical stages I and II according to WHO classification) HIV-infected South African infants. METHODS: a total of 100 HIV-positive infants aged 6 to 10 weeks enrolled in this double-blind, 1:1 randomized, placebo-controlled study were allocated into 2 groups to receive 3 doses of RIX4414 vaccine/placebo according to a 0-, 1-, and 2-month schedule. Routine vaccines were concomitantly administered. Solicited and unsolicited symptoms were recorded for 15 and 31 days after each dose, respectively. Serious adverse events were recorded throughout the study period. Serum antirotavirus IgA concentrations (enzyme-linked immunosorbent assay, cut-off ≥ 20 U/mL) and the immunodeficiency status were determined at screening and 2 months post-Dose 3. Stool samples were analyzed for rotavirus using enzyme-linked immunosorbent assay at predetermined points and during diarrhea episodes. RESULTS: all symptoms (solicited and unsolicited) occurred at a similar frequency in both groups. Six fatal serious adverse events in RIX4414 and 9 in placebo groups were reported. At 2 months post-Dose 3, the seroconversion rates were 57.1% (95% CI: 34-78.2) in RIX4414 and 18.2% (95% CI: 5.2-40.3) in the placebo group. The mean absolute CD4 cell count, CD4 percentage, and HIV-1 viral load were comparable in both groups at screening and 2 months post-Dose 3. Rotavirus shedding peaked at Day 7 after Dose 1 of RIX4414 with prolonged shedding was observed in 1 infant only. CONCLUSIONS: : Three doses of RIX4414 vaccine was tolerated well by the South African HIV-positive infants. A satisfactory immune response was mounted without aggravating their immunologic or HIV condition.
