    Background. Maturing of the burgeoning HIV epidemic in South Africa has resulted in an increased demand for intensive care. Objectives. To investigate the influence of ethical dilemmas facing South African intensivists on decisions about access to intensive care for patients with HIV infection in resource-limited settings. Methods. A cross-sectional, descriptive, quantitative, analytical, anonymous attitudes-and-perception questionnaire survey of 90 intensivists. The main outcome measure was the rating of factors influencing decisions on admission to intensive care and responses to 5 hypothetical clinical scenarios. Results. The number of intensivists who considered the prognosis of the acute disease and of the underlying disease to be most important was 87.9% (n=74). Most (71.6%; n=63) intensivists cited availability of an intensive care unit (ICU) bed as influencing the decision to admit. Intensivists comprising 26.8% (n=22) of the total group rated as probably important or least important the ‘resources available’; ‘bed used to the prejudice of another patient’ was stated by 16.4% (n=14); and ‘policy of the intensive care unit’ by 17% (n=14). Nearly two-thirds (65.9%; n=58) would respect an informed refusal of treatment. A similar number would comply with a written ‘Do not resuscitate’ (DNR) order. In patients with no real chance of recovering a meaningful life, 81.6% (n=71) of intensivists would withhold sophisticated therapy (e.g. not start mechanical ventilation or dialysis etc.) and 75.9% (n=63) would withdraw sophisticated therapy (e.g. discontinue mechanical ventilation, dialysis etc.). Conclusions. A combination of factors was identified as influencing the decision to admit patients to intensive care. Prognosis and disease status were identified as the main factors influencing admission. Patients with HIV/AIDS were not discriminated against in admission to intensive care

    In resource-constrained settings and in the context of HIV-infected patients requiring intensive care, value-laden decisions by critical care specialists are often made in the absence of explicit policies and guidelines. These are often based on individual practitioners’ knowledge and experience, which may be subject to bias. We reviewed published information on legislation and practices related to intensive care unit (ICU) admission in India, Brazil and South Africa, to assess access to critical care services in the context of HIV. Each of these countries has legal instruments in place to provide their citizens with health services, but they differ in their provision of ICU care for HIV-infected persons. In Brazil, some ICUs have no admission criteria, and this decision vests solely on the ‘availability, and the knowledge and the experience’ of the most experienced ICU specialist at the institution. India has few regulatory mechanisms to ensure ICU care for critically ill patients including HIV-infected persons. SA has made concerted efforts towards non-discriminatory criteria for ICU admissions and, despite the shortage of ICU beds, HIV infected patients have relatively greater access to this level of care than in other developing countries in Africa, such as Botswana. Policymakers and clinicians should devise explicit policy frameworks to govern ICU admissions in the context of HIV status

    To determine the feasibility and effectiveness of integrating highly active antiretroviral therapy (HAART) into existing tuberculosis directly observed therapy (TB/DOT) programs, we performed a pilot study in an urban TB clinic in South Africa. Patients with smear-positive pulmonary TB were offered HIV counseling and testing. Twenty HIV-positive patients received once-daily didanosine (400 mg) plus lamivudine (300 mg) plus efavirenz (600 mg) administered concomitantly with standard TB therapy Monday to Friday and self-administered on weekends. After completing TB therapy, patients were referred to an HIV clinic for continued treatment. At baseline, patients had a mean CD4 count of 230 cells/mm3 (range: 24–499 cells/mm3) and a mean viral load of 5.75 log10 (range: 3.81–7.53 log10). Seventeen completed combined standard TB and HIV therapy; 16 of 20 (80%) patients enrolled and 15 of 17 (88%) patients completing standard TB therapy achieved a viral load <50 copies/mL and mean CD4 count increase of 148 cells/mm3. TB was cured in 17 of 20 (85%) enrolled patients and 17 of 19 (89%) patients with drug-sensitive TB. Treatment was well tolerated, with minimal gastrointestinal, hepatic, skin, or neurologic toxicity. The project was well accepted and integrated into the daily TB clinic functions. This pilot study demonstrates that TB/DOT programs can be feasible and effective sites for HIV identification and the introduction and monitoring of a once-daily HAART regimen in resource-limited settings

    CAPRISA, 2014.The aim of this investigation was to identify factors associated with HIV transmission risk behavior among HIV-positive women and men receiving antiretroviral therapy (ART) in KwaZulu-Natal, South Africa. Across 16 clinics, 1,890 HIV? patients on ART completed a risk-focused audio computer-assisted self-interview upon enrolling in a prevention-with-positives intervention trial. Results demonstrated that 62% of HIV-positive patients’ recent unprotected sexual acts involved HIV-negative or HIV status unknown partners. For HIV-positive women, multivariable correlates of unprotected sex with HIV-negative or HIV status unknown partners were indicative of poor HIV prevention-related information and of sexual partnership-associated behavioral skills barriers. For HIV positive men, multivariable correlates represented motivational barriers, characterized by negative condom attitudes and the experience of depressive symptomatology, as well as possible underlying information deficits. Findings suggest that interventions addressing gender-specific and culturally-relevant information, motivation, and behavioral skills barriers could help reduce HIV transmission risk behavior among HIV-positive South Africans

    Objective To revise the South African guideline for the management of COPD based on emerging research that has informed updated recommendations. Key points Smoking is the major cause of COPD, HIV infection, exposure to biomass fuels and tuberculosis are important additional factors. Spirometry is important for the diagnosis of COPD. COPD is either undiagnosed or diagnosed too late, thus limiting the benefit of therapeutic interventions; performing spirometry in at-risk individuals will help to identify COPD early. COPD should be managed as a multisystem disease with attention to comorbidities, particularly cardiovascular disease. Primary and secondary prevention are the most cost-effective strategies in managing COPD. Smoking cessation as well as avoidance of other risk factors can prevent the development of COPD and retard disease progression. Bronchodilators [long-acting muscarinic antagonist (LAMA) or long-acting beta-2 agonists (LABA)] are the mainstay of pharmacotherapy, relieving dyspnoea, reducing acute exacerbations, reducing rate of disease progression and improving quality of life. Inhaled corticosteroids (ICS) are recommended in patients with frequent exacerbations and those with peripheral blood eosinophilia and have a synergistic effect with bronchodilators in improving lung function, quality of life and reducing exacerbation frequency. Oral corticosteroids are not recommended for maintenance treatment of COPD. A therapeutic trial of oral corticosteroids to distinguish corticosteroid responders from non-responders is not recommended. Acute exacerbations of COPD contribute significantly to health care costs, accelerates loss of lung function and increases mortality. A short course of oral corticosteroids (5 days) has been shown to be beneficial in acute exacerbations. Antibiotics are indicated during acute exacerbations associated with purulent sputum. Lifestyle modification, pulmonary rehabilitation (PR), pneumococcal vaccination and annual influenza vaccination are recommended for COPD patients

    Summary: Background: Tuberculosis (TB) is an infectious morbidity that commonly occurs in people living with HIV (PWH) and increases the progression of HIV disease, as well as the risk of death. Simple markers of progression are much needed to identify those at highest risk for poor outcome. This study aimed to assess how baseline severity of anaemia and associated inflammatory profiles impact death and the incidence of TB in a cohort of PWH who received TB preventive therapy (TPT). Methods: This study is a secondary posthoc analysis of the AIDS Clinical Trials Group A5274 REMEMBER clinical trial (NCT0138008), an open-label randomised clinical trial of antiretroviral-naïve PWH with CD4 <50 cells/μL, performed from October 31, 2011 to June 9, 2014, from 18 outpatient research clinics in 10 low- and middle-income countries (Malawi, South Africa, Haiti, Kenya, Zambia, India, Brazil, Zimbabwe, Peru, and Uganda) who initiated antiretroviral therapy and either isoniazid TPT or 4-drug empiric TB therapy. Plasma concentrations of several soluble inflammatory biomarkers were measured prior to the commencement of antiretroviral and anti-TB therapies, and participants were followed up for at least 48 weeks. Incident TB or death during this period were primary outcomes. We performed multidimensional analyses, logistic regression analyses, survival curves, and Bayesian network analyses to delineate associations between anaemia, laboratory parameters, and clinical outcomes. Findings: Of all 269 participants, 76.2% (n = 205) were anaemic, and 31.2% (n = 84) had severe anaemia. PWH with moderate/severe anaemia exhibited a pronounced systemic pro-inflammatory profile compared to those with mild or without anaemia, hallmarked by a substantial increase in IL-6 plasma concentrations. Moderate/severe anaemia was also associated with incident TB incidence (aOR: 3.59, 95% CI: 1.32–9.76, p = 0.012) and death (aOR: 3.63, 95% CI: 1.07–12.33, p = 0.039). Interpretation: Our findings suggest that PWH with moderate/severe anaemia display a distinct pro-inflammatory profile. The presence of moderate/severe anaemia pre-ART was independently associated with the development of TB and death. PWH with anaemia should be monitored closely to minimise the occurrence of unfavourable outcomes. Funding: National Institutes of Health
