    ABSTRACT: Antiretroviral therapy (ART) clinic populations have expanded enormously in the successful Malawi ART scale-up programme. Overcrowding, long waiting times and living far away from the clinic may affect the extent to which patients use their ART clinic for intercurrent illnesses. We interviewed patients of a large urban ART clinic in Blantyre, Malawi, during routine visits about the choice of health care facility during recent illness episodes. Out of 346 enrolled adults, mean age 39.8 (range 18-70) years, 54.3% female, 202 (58%) reported one or more illness in the past 6 months, during which 85 (42.1%; 95%-confidence interval: 36.9-47.3%) did not utilize their own clinic. Long distance to the clinic was the main subjective reason, while low education attainment, rural residence, perceived mild illness and dissatisfaction with the ART service were associated with not using their own clinic in multivariate analyses. Of all participants, 83.6% were satisfied with the service provided; only 6.1% were aware of the full service package of the ART clinic. ART patients often seek health care outside their own clinic, which may have detrimental effects, and has consequences for ART counseling content and reporting of ART information in health passports.

  • Article: Cardiovascular risk factors in adult Malawians on long-term antiretroviral therapy.
    [show abstract] [hide abstract]
    ABSTRACT: Around 225,000 patients currently receive antiretroviral therapy (ART) in the Malawi scale-up programme that uses the public health approach to ART. There are concerns that cardiovascular disease risk factors are common in ART patients, but few data exist from sub-Saharan Africa, and none from Malawi. We did a cross-sectional study of cardiovascular risk factors in urban, adult, Malawian ART patients, with the WHO STEP-wise surveillance tool. We enrolled 174 long-term (>1 year) ART patients during routine clinic visits, mean age 40.8 years (range 18-69), 61.5% female, 97.1% on first-line regimens, median duration ART 35.5 months. Insufficient fruit and vegetable diet (67.6%), raised blood pressure (45.9%), increased waist-hip ratio (45.4%), raised total cholesterol levels (31.0%) and low physical activity level (27.0%) were common, while current smoking (0.6%), current alcohol consumption (2.3%) and elevated glucose levels (1.2%) were rare. In multivariable analyses, higher age was associated with low physical activity, raised blood pressure, being overweight, and increased waist-hip ratio. Longer duration of ART was not associated with any risk factor and was protective for being overweight. Cardiovascular risk factors were common among long-term ART patients in Malawi. This requires more attention and further study in programmes using the public health approach to ART.

  • Article: Applying lessons learnt from the 'DOTS' Tuberculosis Model to monitoring and evaluating persons with diabetes mellitus in Blantyre, Malawi.
    [show abstract] [hide abstract]
    ABSTRACT: The global burden of diabetes mellitus (DM) is immense and predicted to reach 438 million by 2030, with 80% of the cases being in the developing world. The management of chronic non-communicable diseases like DM is poor in most resource-limited settings, and the 'directly observed therapy, short course' (DOTS) framework for tuberculosis control has been proposed as a feasible way to improve this situation. In late 2009, aspects of the DOTS model were applied to the management of persons with DM in the diabetes clinic in Queen Elizabeth Central Hospital, Blantyre, Malawi, and a point-of-care electronic medical record system was set up to support and monitor patients in care. This is the first quarterly and cumulative report of persons with DM registered for care stratified by treatment outcomes, complications and medication history up to 31 December 2010. There were 170 new patients registered between October and December 2010, with 1864 ever registered by 31 December 2010. Most patients were alive and in care; 3 died, 53 defaulted and 3 transferred out. Of those on oral hypoglycaemic agents, metformin was most commonly used. Complications were common. The monitoring and evaluation will be further refined, and at the same time, the systems developed in Blantyre will be expanded to other parts of the country.

  • Article: The benefit of supplementary feeding for wasted Malawian adults initiating ART.
    [show abstract] [hide abstract]
    ABSTRACT: Food insecurity is considered to be an important contributor to HIV associated wasting in sub-Saharan Africa. Low body mass index (BMI) is a strong risk factor for early mortality during antiretroviral therapy (ART). Nutritional supplementation has become standard of care in wasted patients starting ART in many countries in the region, but there is no unequivocal evidence base for this intervention. Against this background, we performed a retrospective study to compare food supplementation versus no nutritional intervention in wasted adults starting ART in Blantyre, Malawi. All patients received free nevirapine, lamivudine, and stavudine. Participants in an effectiveness trial of two food supplements received either corn-soy blend (CSB) or ready-to-use food spread (RUFS) during the first 14 weeks of ART. Results were compared with a historical control group receiving no food supplement that was part of an observational cohort study of outcomes of the same ART regimen. Characteristics on initiation of ART were similar in the three groups, except the use of cotrimoxazole prophylaxis which was more frequent in the food-supplemented groups. Linear regression analysis showed that increase in BMI was greatest in the RUFS group and better in the CSB group than in those receiving no food supplementation at 14 weeks. These differences were no longer significant at 26 weeks. Lower BMI, CD4 count and hemoglobin, WHO clinical stage IV, male gender, and not receiving cotrimoxazole prophylaxis were independent risk factors for mortality at 14 and 26 weeks in the logistic regression analysis. Supplementary food use was not directly associated with improved survival.

    Article: Supplementary feeding in the care of the wasted HIV infected patient.

    ABSTRACT: Wasting and food insecurity are commonly seen in patients receiving antiretroviral treatment (ART) programs in sub-Saharan Africa and south Asia, and supplementary feeding is often offered in conjunction with ART. Evidence for the effectiveness of such supplementary feeding is scant. A randomised, investigator-blinded, controlled clinical trial of two types of supplementary food, corn/soy blended flour and a ready-to-use peanut butter-based lipid paste, in wasted adults in Blantyre, Malawi is described and the results summarised. A historical control group who did not receive supplementary food is described as well. Provision of about half of the daily energy requirement as a supplementary food for 14 weeks resulted in more rapid restoration of a normal BMI; and the energy-dense, ready-to-use paste was associated with more rapid weight gain than the blended flour. Survival was similar among the 3 groups. The strong association between lower BMI and survival indirectly suggests that there may well be clinical benefit from supplementary feeding in this population. No differences were seen in ART adherence or quality of life with more rapid restoration of BMI. Further research is urgently needed concerning the widespread practice of supplementary feeding in HIV/AIDS care to most effectively utilize this intervention.

    Article: Post exposure prophylaxis of HIV transmission after occupational injuries in Queen Elizabeth Central Hospital, Blantyre, Malawi, 2003 - 2008.
    [show abstract] [hide abstract]
    ABSTRACT: Health care worker (HCW) in Malawi may acquire HIV infection through occupational injuries, in particular since HIV prevalence among inpatients and incidence of occupational injuries are high. A post exposure prophylaxis (PEP) programme for occupational injuries at Queen Elizabeth Central Hospital (QECH) commenced in 2003. We performed an audit of this programme from 2003 through 2008. 203 Occupational injuries were reported. The majority were needle stick injuries (76.3%). Half of the clients were in a training position. A dual ART regimen was most frequently prescribed. Triple therapy use increased over time and was more frequent in expatriate students. Many nurses and clinical officers were not fully vaccinated for HBV. Based on previous incidence data, occupational injuries were likely to be underreported. Data on side effects were incomplete, however PEP discontinuation due to side effects occurred only twice. Follow up visits were poorly attended, therefore the efficacy of PEP could not be evaluated. Prevention efforts for occupational injuries should be increased and specifically target HCWs in training positions. Measures to improve quality of the PEP programme include effective publicity campaigns, compulsory Hepatitis B vaccination and active tracing of HCWs who default follow up after PEP.

    Article: Diagnosis and management of antiretroviral-therapy failure in resource-limited settings in sub-Saharan Africa: challenges and perspectives.
    [show abstract] [hide abstract]
    ABSTRACT: Despite the enormous progress made in scaling up antiretroviral therapy (ART) in sub-Saharan Africa, many challenges remain, not least of which are the identification and management of patients who have failed first-line therapy. Less than 3% of patients are receiving second-line treatment at present, whereas 15-25% of patients have detectable viral loads 12 months or more into treatment, of whom a substantial proportion might have virological failure. We discuss the reasons why virological ART failure is likely to be under-diagnosed in the routine health system, and address the current difficulties with standard recommended second-line ART regimens. The development of new diagnostic tools for ART failure, in particular a point-of-care HIV viral-load test, combined with simple and inexpensive second-line therapy, such as boosted protease-inhibitor monotherapy, could revolutionise the management of ART failure in resource-limited settings.

  • Article: Evaluation of antiretroviral therapy results in a resource-poor setting in Blantyre, Malawi.
    [show abstract] [hide abstract]
    ABSTRACT: To evaluate treatment results of the paying antiretroviral therapy (ART) clinic of Queen Elizabeth Central Hospital, a large public and teaching hospital in Blantyre, Malawi. The only ART was a fixed drug combination of stavudine, lamivudine and nevirapine. Cross sectional study with interviews, laboratory tests (CD4 count, viral load, nevirapine plasma levels, transaminases) and data extraction from files. A total of 422 (59%) of the patients who started ART since 2000 were lost to follow-up. The 176 patients enrolled in the study had good virological and excellent clinical treatment results. The most common side effect was peripheral neuropathy. Nevirapine plasma levels were remarkably high and associated with successful virological treatment results. Two simple adherence questions pertaining to the use of medication in the previous 8 days corresponded well with nevirapine levels. The most important reasons for non-adherence were shortage of drugs in the hospital pharmacy and personal financial constraints. (1) Many patients were lost to follow-up. (2) High nevirapine levels contributed to good therapy results in those studied. (3) Simple adherence questions predicted subtherapeutic nevirapine levels. (4) Antiretroviral drug supply needs to be uninterrupted and free of charge, to prevent avoidable non-adherence.
