The first XDR-TB case in the Western Cape province of South Africa was recorded in 1992, approximately 5 - 7 years after the regional introduction of MDR-TB-like treatment. Between 1990 and 2002 we identified 48 patients with XDR-TB in the Cape Metropole region of the Western Cape province. Patients were predominantly HIV-uninfected and median survival was 10.8 months. XDR-TB has therefore been present in the Western Cape at least since 1992. These data inform public health policy relevant to the introduction of new anti-TB drug regimens. <![CDATA[<b>Patient retention gifts in clinical trials: undue inducement or justified motivational tools?</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742011000900019&lng=en&nrm=iso&tlng=en The use of retention gifts in clinical trials has been controversial, with some ethicists maintaining that such gifts represent undue inducement to the trial participants. A study was conducted at TREAD Research, a site-managed organisation based at Tygerberg Hospital, in which 302 participants completed a questionnaire that focused on their opinion with regard to such gifts. The results suggest that these gifts do not influence patients to participate in a clinical trial or influence them to remain on a trial should they wish to withdraw. However, they do act as a useful motivational tool and trial participants appreciate them. <![CDATA[<b>Should baseline PSA testing be performed in men aged 40 to detect those aged 50 or less who are at risk of aggressive prostate cancer?</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742011000900020&lng=en&nrm=iso&tlng=en OBJECTIVE: We aimed to evaluate the presenting features and treatment outcome of prostate cancer in men aged <50 years, in a region where prostate specific antigen (PSA) screening is not readily available and most men present with symptoms. METHODS: We analysed the data of 1 571 men with prostatic adenocarcinoma treated between January 1997 and December 2008 at our institution, a tertiary level public sector hospital serving a largely indigent population. Statistical analysis was performed using Student's, the Mann-Whitney and Fisher's exact tests where appropriate (p<0.05 accepted as statistically significant). RESULTS: Of 1 571 men, 47 (3%) were aged <50 years. The group aged <50 years, compared with that aged &gt;50 years, had a significantly greater proportion with poorly differentiated adenocarcinoma (53%), locally advanced (stage T3 - 4) tumours (56%), haematogenous metastases (75%), significantly higher serum PSA at diagnosis (mean 621, median 74 ng/ml) and shorter survival. CONCLUSIONS: Men aged <50 years presenting with symptoms owing to prostate cancer had significantly higher-risk disease, higher mean PSA, and poorer prognosis than men aged &gt;50 years. To diagnose prostate cancer at a potentially curable stage in men aged <50 years, it is necessary to initiate baseline PSA testing at age 40 and 45 years, and to select high-risk men for PSA surveillance in order to diagnose potentially curable cancer in those with a life expectancy &gt;20 - 25 years. <![CDATA[<b>Weight evolution and perceptions of adults living with HIV following initiation of antiretroviral therapy in a South African urban setting</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742011000900021&lng=en&nrm=iso&tlng=en BACKGROUND: Obesity and undernutrition are common in South Africa and influence the health outcomes of people living with the human immunodeficiency virus (PLHIV). Aim. To describe the anthropometric changes and perceptions of body weight in adults initiated on antiretroviral therapy (ART). METHODS: A cohort of 230 PLHIV was enrolled at an HIV clinic in Durban. Changes in their body mass index, and waist and hip girth were measured 6-monthly in the 12 months following initiation of ART. Data on demographic and socio-economic variables, CD4 counts, opportunistic infections and drug regimens used were recorded. Perceptions of body weight and desire to change these were ascertained. RESULTS: Weight perceptions of respondents were incongruent with their body mass index, with the trend being to judge themselves as weighing less than their actual weight. Those wanting to gain weight gained an average of 7.8 kg - 2.8 times more than those satisfied with their weight (p<0.001). After 12 months on ART, there was a statistically significant increase in anthropometric measurements (p<0.001) with 43 of the 110 women having waist circumferences that increased their risk of cardiovascular disease; the incidence of lipodystrophy was 35% (62/177) (95% confidence interval 27 - 42%), 36% (64/177) were overweight and 22% (39/177) were obese, compared with 21% (49/230) and 12% (28/230) respectively at baseline (p=0.002). CONCLUSION: There is a strong association between PLHIV's perception of body weight, their desire to gain weight and their actual weight gain on ART. Lipodystrophy, weight gain and truncal obesity are common among PLHIV after initiating ART. <![CDATA[<b>Dual and triple therapy to prevent mother-to-child transmission of HIV in a resource-limited setting: lessons from a South African programme</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742011000900022&lng=en&nrm=iso&tlng=en OBJECTIVE: To determine outcomes of pregnant women and their infants at McCord Hospital in Durban, South Africa, where dual and triple therapy to reduce HIV vertical transmission have been used since 2004 despite national guidelines recommending simpler regimens. METHOD: We retrospectively examined records of all pregnant women attending McCord Hospital for their first antenatal visit between 1 March 2004 and 28 February 2007. Uptake of HIV testing and HIV prevalence were determined, and clinical, immunological and virological outcomes of HIV-positive women and their infants, followed through to 6 months after delivery, were described. RESULTS: The antenatal clinic was attended by 5 303 women; 4 891 (92%) had an HIV test, and 703 (14%) were HIV positive. The HIV-positive women were subsequently followed up: 653 (93%) received antiretroviral therapy or prophylaxis, including 424 (60%) who received triple therapy. Of the 699 live babies delivered, 661 (94%) received prophylaxis. At 6 weeks 571 babies (82%) were brought back for HIV testing; 16 (2.8%) were HIV positive. After 6 months, only 150 women (21%) were receiving follow-up care at the adult HIV clinic. CONCLUSION: Where a tailored approach to prevention of motherto- child transmission (PMTCT) is used, which attempts to maximise available technology and resources, good short-term transmission outcomes can be achieved. However, longer-term follow-up of mothers' and babies' health presents a challenge. Successful strategies to link women to ongoing care are crucial to sustain the gains of PMTCT programmes. <![CDATA[<b>Nevirapine plasma concentrations in premature infants exposed to single-dose nevirapine for prevention of mother-to-child transmission of HIV-1</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742011000900023&lng=en&nrm=iso&tlng=en BACKGROUND: No pharmacokinetic data exist for premature infants receiving single-dose nevirapine (sd NVP) for prevention of mother-to-child transmission (MTCT) of HIV. Aim. To describe NVP decay pharmacokinetics in two groups of premature infants - those whose mothers either received or did not receive NVP during labour. METHODS: Infants less than 37 weeks' gestation were prospectively enrolled. Mothers received sd NVP during labour if time allowed. Infants received sd NVP and zidovudine. Blood was collected on specified days after birth and NVP concentrations were determined by liquid chromatography-mass spectrometry. RESULTS: Data were obtained from 81 infants, 58 born to mothers who received sd NVP during labour (group I) and 23 to mothers who did not receive NVP (group II). Of the infants 29.6% were small for gestational age (SGA). Median (range) maximum concentration (Cmax), time to reach maximum concentration (Tmax), area under the plasma concentration-time curve (AUC) and halflife (T½) were 1 438 (350 - 3 832) ng/ml, 25h50 (9h40 - 83h45), 174 134 (22 308 - 546 408) ng×h/ml and 59.0 (15.4 - 532.6) hours for group I and 1 535 (635 - 4 218) ng/ml, 17h35 (7h40 - 29h), 168 576 (20 268 - 476 712) ng×h/ml and 69.0 (22.12 - 172.3) hours for group II. For group II, the median (range) volume of distribution (Vd) and body clearance (Cl) were 1 702.6 (623.7 - 6 189.8) ml and 34.9 (6.2 - 163.8) ml/h. The AUC was higher (p=0.006) and Cl lower (p<0.0001) in SGA infants. Plasma concentrations exceeding 100 ng/ml were achieved over 8 days in 78% infants in group I and 70.0% in group II. The MTCT rate was 4.8%. CONCLUSION: Women in preterm labour often deliver with little advance warning. Our study suggests that NVP dosing of preterm infants as soon as possible after birth without maternal intrapartum dosing may be as effective as combined maternal and infant dosing. <![CDATA[<b>Potential impact of reactive vaccination in controlling cholera outbreaks</b>: <b>an exploratory analysis using a Zimbabwean experience</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742011000900024&lng=en&nrm=iso&tlng=en BACKGROUND: To contain ongoing cholera outbreaks, the World Health Organization has suggested that reactive vaccination should be considered in addition to its previous control measures. OBJECTIVES: To explore the potential impact of a hypothetical reactive oral cholera vaccination using the example of the recent large-scale cholera outbreak in Zimbabwe. Methods. This was a retrospective cost-effectiveness analysis calculating the health and economic burden of the cholera outbreak in Zimbabwe with and without reactive vaccination. The primary outcome measure was incremental cost per disability-adjusted life year (DALY) averted. RESULTS: Under the base-case assumptions (assuming 50% coverage among individuals aged >2 years), reactive vaccination could have averted 1 320 deaths and 23 650 DALYs. Considering herd immunity, the corresponding values would have been 2 920 deaths and 52 360 DALYs averted. The total vaccination costs would have been ~$74 million and ~$21 million, respectively, with per-dose vaccine price of US$5 and $1. The incremental costs per DALY averted of reactive vaccination were $2 770 and $370, respectively, for vaccine price set at $5 and $1. Assuming herd immunity, the corresponding cost was $980 with vaccine price of $5, and the programme was cost-saving with a vaccine price of $1. Results were most sensitive to case-fatality rate, per-dose vaccine price, and the size of the outbreak. CONCLUSION: Reactive vaccination has the potential to be a costeffective measure to contain cholera outbreaks in countries at high risk. However, the feasibility of implementation should be further evaluated, and caution is warranted in extrapolating the findings to different settings in the absence of other in-depth studies. <![CDATA[<b>Newborn hearing screening in the private health care sector: a national survey</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742011000900025&lng=en&nrm=iso&tlng=en OBJECTIVES: To determine: (i) the national status of newborn hearing screening services in the private health care sector of South Africa; (ii) screening approaches implemented; and (iii) challenges to screening implementation. DESIGN: A descriptive quantitative national survey was conducted in the private sector of South Africa. METHOD: All private health sector institutions with obstetric units (N=166) were surveyed telephonically and self-administered questionnaires were subsequently sent to all audiologists in private practice (N=87) who provide newborn hearing screening services at the units with hearing screening. RESULTS: Nationally 53% of private sector obstetric units offer some form of newborn hearing screening. Universal hearing screening was only offered by 14% of units, while the most common approaches were universal screening on some days of the week (18%) and screening on request (18%). The most prominent challenge to successful screening implementation was the omission of newborn hearing screening from maternity birthing packages at the health care institutions. CONCLUSION: The vast majority of newborns nationally are not screened for hearing loss, and existing programmes are not sufficiently systematic and integrated to ensure adequate coverage. Hospital management and paediatric health services must prioritise hearing screening as part of standard of care in birthing services.
