RESUMO

In 2011, Rwanda's Ministry of Health set a goal of universal access to palliative care by 2020. Toward this audacious egalitarian and humanitarian goal, the Ministry of Health worked with partners to develop palliative care policies and a strategic plan, secure adequate supplies of opioid for the country, initiate palliative care training programs, and begin studying a model for integrating coordinated palliative care into the public health care system at all levels. It also initiated training of a new cadre of home-based care practitioners to provide palliative care in the home. Based on these developments, the goal appears within reach.

RESUMO

A reversed phase HPLC method using photo diode array detection for the simultaneous quantification of lamivudine, stavudine, nevirapine, zidovudine, methyl paraben and propyl paraben in solid and liquid drug formulations was developed and validated. The separation was achieved using a Waters Symmetry C8 column, using a mobile phase gradient comprising 50 mM NaH2PO4 (pH 3.8) and acetonitrile (95:5 to 45:55, v/v) and a flow gradient (0.5 to 1.0 ml/min). The limits of detection and quantification were below 19 ng/ml and 55 ng/ml respectively. The intra- and inter-day assay precisions were within 4.4% relative standard deviations. The developed method was applied to 12 different generic antiretroviral medications, consisting of tablets, capsules and solutions, produced by two Indian manufacturers and purchased by the Central Agency of Essential Drug Procurement of Rwanda for the ESTHER project in Rwanda. The average content of the antiretroviral agent(s) compared to the labeled amount(s) was 101.4%. Methyl paraben and propyl paraben, added to solutions as preservatives, were within the FDA recommended limits.

RESUMO

OBJECTIVE: To examine the effect of selenium supplementation on CD4 T-cell counts, viral suppression, and time to antiretroviral therapy (ART) initiation in ART-naive HIV-infected patients in Rwanda. METHODS: A multicenter, double-blinded, placebo-controlled, randomized clinical trial was conducted. Eligible patients were HIV-infected adults (≥21 years) who had a CD4 cell count between 400 and 650 cells/µl (ART eligibility was ≤350 cells/µl throughout the trial), and were willing to practice barrier methods of birth control. Patients were randomized to receive once-daily 200 µg selenium tablets or identical placebo. They were followed for 24 months with assessments every 6 months. Declines in CD4 cell counts were modeled using linear regressions with generalized estimating equations and effect modification, and the composite outcome (ART eligible or ART initiation) using Cox proportional-hazards regression, both conducted with intention to treat. RESULTS: Of the 300 participants, 149 received selenium, 202 (67%) were women, and median age was 33.5 years. The rate of CD4 depletion was reduced by 43.8% [95% confidence interval (CI) 7.8-79.8% decrease] in the treatment arm - from mean 3.97 cells/µl per month to mean 2.23 cells/µl per month. We observed 96 composite outcome events - 45 (47%) in the treatment arm. We found no treatment effect for the composite outcome (hazard ratio 1.00, 95% CI 0.66-1.54) or viral suppression (odds ratio 1.18, 95% CI 0.71-1.94). The trial was underpowered for the composite outcome due to a lower-than-anticipated event rate. Adverse events were comparable throughout. CONCLUSIONS: This randomized clinical trial demonstrated that 24-month selenium supplementation significantly reduces the rate of CD4 cell count decline among ART-naive patients.

RESUMO

BACKGROUND: Low levels of serum selenium are associated with increased risk of mortality among HIV+ patients in East Africa. We aim to assess the effect of selenium supplementation on CD4 cell count, HIV viral load, opportunistic infections, and quality of life in HIV-infected patients in Rwanda. METHODS AND DESIGN: A 24-month, multi-centre, patient and provider-blinded, randomized, placebo-controlled clinical trial involving 300 pre-antiretroviral therapy (ART) HIV-infected patients will be carried out at two sites in Rwanda. Patients ≥ 21 years of age with documented HIV infection, CD4 cell count of 400-650 cells/mm3, and not yet on ART will be recruited. Patients will be randomized at each study site using a randomized block design to receive either the selenium micronutrient supplement or an identically appearing placebo taken once daily. The primary outcome is a composite of time from baseline to reduction of CD4 T lymphocyte count below 350 cells/mm3 (confirmed by two measures at least one week apart), or start of ART, or the emergence of a documented CDC-defined AIDS-defining illness. An intention-to-treat analysis will be conducted using stepwise regression and structural equation modeling. DISCUSSION: Micronutrient interventions that aim to improve CD4 cell count, decrease opportunistic infections, decrease HIV viral load, and ultimately delay initiation of more costly ART may be beneficial, particularly in resource-constrained settings, such as sub-Saharan Africa. Additional trials are needed to determine if micro-supplementation can delay the need for more costly ART among HIV-infected patients. If shown to be effective, selenium supplementation may be of public health importance to HIV-infected populations, particularly in sub-Saharan Africa and other resource-constrained settings.

RESUMO

An accurate, selective, and sensitive method for the determination of the nonnucleoside reverse transcriptase inhibitors (NNRTIs) nevirapine (nvp) and efavirenz (efv) in human plasma using gas chromatography-mass spectroscopy in selected ion monitoring mode (GC/MS-SIM) was developed. Solid-phase extraction (SPE) gave extraction yields near 100% for both nvp and efv, and calibration curves were linear over the therapeutic concentration ranges. Variation of intraday and interday precision was below 5%. Intraday and interday inaccuracies varied between 0.6% and 10.4%. The lower limits of detection using a 200-microL plasma sample were 27 ng/mL for nvp and 26 ng/mL for efv, and the lower limits of quantification were 54 ng/mL and 72 ng/mL, respectively. The method was applied to the determination of nvp and efv in plasma specimens of 73 patients in HIV stage III or IV and on antiretroviral treatment in Kigali, Rwanda.
