RESUMEN

BACKGROUND: The World Health Organization Antiretroviral Treatment Guidelines recommend phasing-out stavudine because of its risk of long-term toxicity. There are two mutational pathways of stavudine resistance with different implications for zidovudine and tenofovir cross-resistance, the primary candidates for replacing stavudine. However, because resistance testing is rarely available in resource-limited settings, it is critical to identify the cross-resistance patterns associated with first-line stavudine failure. METHODS: We analyzed HIV-1 resistance mutations following first-line stavudine failure from 35 publications comprising 1,825 individuals. We also assessed the influence of concomitant nevirapine vs. efavirenz, therapy duration, and HIV-1 subtype on the proportions of mutations associated with zidovudine vs. tenofovir cross-resistance. RESULTS: Mutations with preferential zidovudine activity, K65R or K70E, occurred in 5.3% of individuals. Mutations with preferential tenofovir activity, ≥ two thymidine analog mutations (TAMs) or Q151M, occurred in 22% of individuals. Nevirapine increased the risk of TAMs, K65R, and Q151M. Longer therapy increased the risk of TAMs and Q151M but not K65R. Subtype C and CRF01_AE increased the risk of K65R, but only CRF01_AE increased the risk of K65R without Q151M. CONCLUSIONS: Regardless of concomitant nevirapine vs. efavirenz, therapy duration, or subtype, tenofovir was more likely than zidovudine to retain antiviral activity following first-line d4T therapy.

RESUMEN

An operational research study was conducted in 2019 to assess the quality of data submitted by antimicrobial resistance (AMR) surveillance sites in the Bagmati Province of Nepal to the National Public Health Laboratory for Global Antimicrobial Resistance and Use Surveillance System (GLASS). Measures were implemented to enhance the quality of AMR surveillance by strengthening capacity, improving infrastructure, implementing data sharing guidelines, and supervision. The current study examined reports submitted by surveillance sites in the same province in 2022 to assess whether the data quality had improved since 2019. The availability of infrastructure at the sites was assessed. Of the nine surveillance sites in the province, seven submitted reports in 2022 versus five in 2019. Completeness in reporting improved significantly from 19% in 2019 to 100% in 2022 (p < 0.001). Timely reports were received from two sites in 2019 and only one site in 2022. Specimen-pathogen consistency in accordance with the GLASS guidelines for urine, feces, and genital swab specimens improved, with ≥90% consistency at all sites. Overall, the pathogen-antibacterial consistency improved significantly for each GLASS priority pathogen. The study highlights the importance of dedicated infrastructure and institutional arrangements for AMR surveillance. Similar assessments covering all provinces of the country can provide a more complete country-wide picture.

RESUMEN

OBJECTIVE: To summarize the experience, performance and scientific output of long-running telemedicine networks delivering humanitarian services. METHODS: Nine long-running networks--those operating for five years or more--were identified and seven provided detailed information about their activities, including performance and scientific output. Information was extracted from peer-reviewed papers describing the networks' study design, effectiveness, quality, economics, provision of access to care and sustainability. The strength of the evidence was scored as none, poor, average or good. FINDINGS: The seven networks had been operating for a median of 11 years (range: 5-15). All networks provided clinical tele-consultations for humanitarian purposes using store-and-forward methods and five were also involved in some form of education. The smallest network had 15 experts and the largest had more than 500. The clinical caseload was 50 to 500 cases a year. A total of 59 papers had been published by the networks, and 44 were listed in Medline. Based on study design, the strength of the evidence was generally poor by conventional standards (e.g. 29 papers described non-controlled clinical series). Over half of the papers provided evidence of sustainability and improved access to care. Uncertain funding was a common risk factor. CONCLUSION: Improved collaboration between networks could help attenuate the lack of resources reported by some networks and improve sustainability. Although the evidence base is weak, the networks appear to offer sustainable and clinically useful services. These findings may interest decision-makers in developing countries considering starting, supporting or joining similar telemedicine networks.

RESUMEN

INTRODUCTION: In Sub-Saharan Africa, snakebites are a public health problem. In Ethiopia, clinical cases have been described, but little information exists on snakebites burden and its geographical distribution. The aim of this study was to document the spatial distribution of venomous snakes and snakebites in Ethiopia. METHODOLOGY: In a cross-sectional observational study, venomous snakes were collected during snake catching activities in six Ethiopian hotspot areas between April 2015 and September 2020. Species and habitat were described. In the hotspot areas, routine health information data on reported snakebites was collected in 78 districts and subsequently used to map annual incidence per district. RESULTS: A total of 333 snakes were collected and 14 species were identified. The most prevalent species were Bitis arietans, Bitis arietanus somalica, Echis pyramidum, known as vipers, and Naja pallida, known as cobra. The highest number of snakes (75) was observed in the Northwest and Eastern parts of Ethiopia, mostly in cultivation and man-made farm land, wooded and moist dry savanna. In each hotspot a wide variety of species was observed, although composition was different. The highest snakebite incidence overlapped with the high snakes densities in Northwest Ethiopia. The snakebite annual average incidence at district level was very heterogeneous and ranged from < 15 cases/100,000 inhabitants (44% of the districts) to 309.2 cases/100,000 inhabitants. CONCLUSIONS: Snake diversity and distribution, linked to high incidence of snakebites in the hotspots, suggests a close interconnection between human, animal and environmental systems and could inform the need for antivenoms per geographical locality.

RESUMEN

INTRODUCTION: Timely and appropriate management of snakebites in the tropics is a lifesaver. Many snakebite patients are being bitten in remote rural areas and do not manage to get in due time to healthcare facilities. This study assessed the clinical features and the risk factors associated with treatment outcomes of snakebite patients admitted at two hospitals in the Northwest of Ethiopia. METHODOLOGY: In a retrospective cohort study, routinely collected data from 250 patients' medical charts at University of Gondar Hospital and Metema Hospital, between September 2012 and August 2020, were reviewed. RESULTS: The median age of the snakebite cases was 24 years (95% CI = 22-26), with 80.8% male patients. At admission 148/250 patients presented in Clinical stage 1 or 2 (local symptoms only) and 73.7% presented more than 12 hours after the bite, 80.2% received antibiotics and 79.0% antivenom. The median duration of hospitalization was 3 days (95% CI = 3-4); 72% of the patients recovered and were discharged, 10.8% died and 0.5% underwent an amputation. On logistic regression analysis, residence in rural areas (AOR = 2.52, 95 % CI = 1.2-5.3), sign of bacterial superinfection on the bite site (AOR = 4.69. 95% CI = 1.4-15.4), clinical stage 3 or 4 with systemic symptoms or toxic signs at admission (AOR = 4.84, 95% CI = 1.3-18.0) and no treatment with antivenoms (AOR = 6.65, 95% CI = 1.6-27.7) were associated with bad outcome (death, amputation and/or referred/ went against medical advice). CONCLUSIONS: Timely presentation at early clinical stage, appropriate clinical management and availability of antivenoms are cornerstones to reduce snakebite morbidity and mortality.

RESUMEN

INTRODUCTION: Trachomatous trichiasis (TT) is the advanced stage of trachoma where lashes touch the globe of the eye causing permanent damage. Without eyelid surgery, TT can lead to irreversible blindness. In 2015 the Ethiopian Ministry of Health launched the Fast Track Initiative with the aim of enhancing the provision of surgical services for TT. The aims of this study were to determine the productivity of individual surgeons during the 2017 Initiative, to compare this productivity with the Ministry's annual target indicator of ≥ 200 surgeries, and to assess the factors associated with surgical output. METHODOLOGY: This retrospective cross-sectional study utilized programmatic data on surgical output from 140 surgeons active from January 2017 through December 2017 in the eastern half of Amhara region, Ethiopia. Data were collected from a surgery monitoring dataset, analyzed, and compared to the performance targets set by the Ministry. RESULTS: The mean annual number of surgeries carried out per surgeon was 169 (standard deviation: 111) for a total of 23,616 surgeries. Among the 140 surgeons, 38% achieved the target set by the Ministry. Location of surgical training site and estimated surgical backlog were signficantly associated with a higher surgery output. CONCLUSIONS: An increase in surgical output was observed compared to productivity prior to the Initiative, although the average annual output during the 2017 Fast Track Initiative was lower than the Ministry's target. Using data driven approaches to setting annual productivity goals should be considered, particularly in light of fewer remaining TT cases as a result of the successful Initiative.

RESUMEN

With safely managed water accessible to only 19% of the population in Ghana, the majority of its residents are at risk of drinking contaminated water. Furthermore, this water could be a potential vehicle for the transmission of antimicrobial-resistant bacteria. This study assessed the presence of bacteria and the antibiotic resistance profile of Escherichia coli and Pseudomonas aeruginosa in drinking-water sources using membrane filtration and Kirby-Bauer disc diffusion methods. A total of 524 water samples were analyzed for total coliforms, total heterotrophic bacteria, E. coli and P. aeruginosa. Samples included sachets, bottled water, tap water, borehole and well water. Most of the sachet and bottled water samples were within the limits of Ghana's standards for safe drinking water for the parameters tested. Over 50% of tap and borehole water was also free of E. coli and P. aeruginosa. Overall, of 115 E. coli isolates from tap and ground water samples, most were resistant to cefuroxime (88.7%), trimethoprim-sulfamethoxazole (62.6%) and amoxicillin-clavulanate (52.2%). P. aeruginosa isolates were most resistant to aztreonam (48%). Multidrug resistance was predominantly seen among E. coli isolates (58%). Evidence from this study calls for routine antimicrobial resistance surveillance in drinking water across the country and additional treatment of water sources at household levels.

RESUMEN

Introduction: Qualitative studies are often inadequately reported, making it difficult to judge their appropriateness for decision making in public health. We assessed the publication characteristics and quality of reporting of qualitative and mixed-method studies from the Structured Operational Research and Training Initiative (SORT IT), a global partnership for operational research capacity building. Methods: A cross-sectional analysis of publications to assess the qualitative component using an adapted version of the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist. Results: In 67 publications involving 18 countries, 32 journals and 13 public health themes, 55 were mixed-methods studies and 12 were qualitative studies. First authorship from low-and-middle-income (LMIC) countries was present in 64 (96%), LMIC last authorship in 55 (82%), and female first authorship in 30 (45%). The mean LMIC institutions represented per publication was five (range 1-11). Sixty-three (94%) publications were open access. Reporting quality was graded as 'good' to 'excellent' in 60 (89%) publications, 'fair' in five (8%) and 'poor' in two (3%). Conclusion: Most SORT IT publications adhered to COREQ standards, while supporting gender equity in authorship and the promotion of LMIC research leadership. SORT IT plays an important role in ensuring quality of evidence for decision making to improve public health.

RESUMEN

OBJECTIVE: To appraise the process of development and clinical content of national human immunodeficiency virus (HIV) clinical practice guidelines of countries in the eastern Mediterranean and to formulate recommendations for future guideline development and adaptation. METHODS: Twenty-three countries in the World Health Organization (WHO) Eastern Mediterranean and United Nations Children's Fund Middle East and North Africa regions were invited to submit national HIV clinical practice guidelines for review. The guideline development methodology was assessed using an adaptation of the Appraisal of Guidelines Research and Evaluation (AGREE) instrument and guideline content, using a checklist to evaluate concordance with WHO 2006 generic guidelines. FINDINGS: Twelve countries submitted 20 guidelines developed between 2004 and 2009. Median scores were poor (i.e. < 0.6) for the methodological quality domains of rigour of development, stakeholder involvement and applicability and flexibility. Scores were better for the domains of scope and purpose (median: 0.82, interquartile range, IQR: 0.58-0.89) and clarity and presentation (median: 0.67, IQR: 0.50-0.78). Concerning guideline content, recommended first-line treatment and eligibility criteria for antiretroviral therapy (ART) in adults were in line with WHO recommendations in most guidelines. However, recommendations on antiretroviral prophylaxis for the prevention of vertical HIV transmission, diagnosis and treatment of HIV infection in infants, monitoring patients on ART, treatment failure and co-morbidities were often lacking. CONCLUSION: The large majority of national HIV clinical practice guidelines had methodological weaknesses and content inaccuracies. Countries require assistance with the adaptation process to ensure that guidelines are valid and up to date and accurately reflect WHO global clinical care recommendations for patients with HIV.

RESUMEN

Globally, 5-15% of hospitalized patients acquire infections (often caused by antimicrobial-resistant microbes) due to inadequate infection prevention and control (IPC) measures. We used the World Health Organization's (WHO) 'Infection Prevention and Control Assessment Framework' (IPCAF) tool to assess the IPC compliance at Lira University hospital (LUH), a teaching hospital in Uganda. We also characterized challenges in completing the tool. This was a hospital-based, cross-sectional study conducted in November 2020. The IPC focal person at LUH completed the WHO IPCAF tool. Responses were validated, scored, and interpreted per WHO guidelines. The overall IPC compliance score at LUH was 225/800 (28.5%), implying a basic IPC compliance level. There was no IPC committee, no IPC team, and no budgets. Training was rarely or never conducted. There was no surveillance system and no monitoring/audit of IPC activities. Bed capacity, water, electricity, and disposal of hospital waste were adequate. Disposables and personal protective equipment were not available in appropriate quantities. Major challenges in completing the IPCAF tool were related to the detailed questions requiring repeated consultation with other hospital stakeholders and the long time it took to complete the tool. IPC compliance at LUH was not optimal. The gaps identified need to be addressed urgently.

RESUMEN

Antimicrobials help in the prevention and treatment of infections and are crucial for animal production, but overuse can result in antimicrobial resistance. Hence, understanding data quality on livestock antimicrobial use is essential. We assessed frequency of reporting, completeness, and concordance of reported data and availability of human resources and infrastructure in 14 districts in Sierra Leone. This was a cross-sectional study involving a review of district and sub-district animal treatment forms submitted from January 2016 to August 2019. Out of the 14 districts, only 3 had filled forms available for review: A total of 6 (0.97% of 616 expected) district forms and 79 (1.15% of 6840 expected) sub-district forms. Data between district and sub-district treatment forms were fully discordant. Hence, completeness of data could not be assessed. All districts had livestock officers (barring one) and livestock assistants but no veterinarians. The gap in community animal health workers ranged from 14 to 100% per district. No districts had a functional computer or internet access. Reporting was non-existent in 11 districts and poor in the other 3. Resources are urgently needed to address critical gaps in human resources and capacity and computer and Internet connectivity to develop critical One Health surveillance functions at the national and sub-national levels.

RESUMEN

Antimicrobial resistance (AMR) is a global problem, and Nepal is no exception. Countries are expected to report annually to the World Health Organization on their AMR surveillance progress through a Global Antimicrobial Resistance Surveillance System, in which Nepal enrolled in 2017. We assessed the quality of AMR surveillance data during 2019-2020 at nine surveillance sites in Province 3 of Nepal for completeness, consistency, and timeliness and examined barriers for non-reporting sites. Here, we present the results of this cross-sectional descriptive study of secondary AMR data from five reporting sites and barriers identified through a structured questionnaire completed by representatives at the five reporting and four non-reporting sites. Among the 1584 records from the reporting sites assessed for consistency and completeness, 77-92% were consistent and 88-100% were complete, with inter-site variation. Data from two sites were received by the 15th day of the following month, whereas receipt was delayed by a mean of 175 days at three other sites. All four non-reporting sites lacked dedicated data personnel, and two lacked computers. The AMR surveillance data collection process needs improvement in completeness, consistency, and timeliness. Non-reporting sites need support to meet the specific requirements for data compilation and sharing.

RESUMEN

BACKGROUND: We present an innovative approach to healthcare worker (HCW) training using mobile phones as a personal learning environment.Twenty physicians used individual Smartphones (Nokia N95 and iPhone), each equipped with a portable solar charger. Doctors worked in urban and peri-urban HIV/AIDS clinics in Peru, where almost 70% of the nation's HIV patients in need are on treatment. A set of 3D learning scenarios simulating interactive clinical cases was developed and adapted to the Smartphones for a continuing medical education program lasting 3 months. A mobile educational platform supporting learning events tracked participant learning progress. A discussion forum accessible via mobile connected participants to a group of HIV specialists available for back-up of the medical information. Learning outcomes were verified through mobile quizzes using multiple choice questions at the end of each module. METHODS: In December 2009, a mid-term evaluation was conducted, targeting both technical feasibility and user satisfaction. It also highlighted user perception of the program and the technical challenges encountered using mobile devices for lifelong learning. RESULTS: With a response rate of 90% (18/20 questionnaires returned), the overall satisfaction of using mobile tools was generally greater for the iPhone. Access to Skype and Facebook, screen/keyboard size, and image quality were cited as more troublesome for the Nokia N95 compared to the iPhone. CONCLUSIONS: Training, supervision and clinical mentoring of health workers are the cornerstone of the scaling up process of HIV/AIDS care in resource-limited settings (RLSs). Educational modules on mobile phones can give flexibility to HCWs for accessing learning content anywhere. However lack of softwares interoperability and the high investment cost for the Smartphones' purchase could represent a limitation to the wide spread use of such kind mLearning programs in RLSs.

RESUMEN

INTRODUCTION: Trachoma is one of the 20 neglected tropical diseases and a serious public health problem in Ethiopia. To reach the WHO elimination target by 2020, SAFE (Surgery, Antibiotics, Facial cleanliness, Environmental improvement) strategy has been implemented in the Southern Nations, Nationalities, and Peoples' Region (SNNPRs), Ethiopia. Scarce evidence exists regarding recent progress in achieving elimination of active trachoma (< 5%) and how well the SAFE strategy implemented. METHODOLOGY: A retrospective analysis of programmatic data in the period 2013-2018 was used. All trachoma endemic districts in SNNPR were included. Data collected from the Federal Ministry of Health on trachoma prevalence and SAFE strategy were analyzed. RESULTS: Out of 134 endemic districts, only 35 had their planned impact survey, of which only 11 districts achieved the elimination target. Six districts reverted backwards from eliminated status to low (1) or moderate (5) level. The median prevalence of active trachoma in these 35 districts was 10% in 2017/18. In 2017, the mean antibiotic treatment coverage was 90%, but only 56% and 68% of districts implemented and reported on "F" and "E" components, respectively. In the high prevalence districts, only 10% delivered their planned five rounds of Zithromax® mass distribution. CONCLUSIONS: These data showed a lack in planned impact surveys with only a limited number of districts reached the WHO elimination threshold by 2018. Lack of attention on high prevalent districts, and recent reversal of trachoma eliminated districts to moderate or low prevalence levels argue for urgent and prioritized implementation of the SAFE strategy.

RESUMEN

Early infant diagnosis (EID) of HIV provides an opportunity for early HIV detection and access to appropriate Antiretroviral treatment (ART). Dried Blood Spot (DBS) samples are used for EID of exposed infants, born to HIV-positive mothers. However, DBS rejection rates in Zimbabwe have been exceeding the target of less than 2% per month set by the National Microbiology Reference Laboratory (NMRL), in Harare. The aim of this study was to determine the DBS sample rejection rate, the reasons for rejection and the possible associations between rejection and level of health facility where the samples were collected. This is an analytical cross-sectional study using routine DBS sample data from the NMRL in Harare, Zimbabwe, between January and December 2017.A total of 34 950 DBS samples were received at the NMRL. Of these, 1291(4%) were rejected. Reasons for rejection were insufficient specimen volume (72%), missing request form (11%), missing sample (6%), cross-contamination (6%), mismatch of information (4%) and clotted sample (1%). Samples collected from clinics/rural health facilities were five times more likely to be rejected compared to those from a central hospital. Rejection rates were above the set target of <2%. The reasons for rejection were 'pre-analytical' errors including labelling errors, missing or inconsistent data, and insufficient blood collected. Samples collected at primary healthcare facilities had higher rejection rates.

RESUMEN

BACKGROUND: Despite the great impact of information and communication technologies on clinical practice and on the quality of health services, this trend has been almost exclusive to developed countries, whereas countries with poor resources suffer from many economic and social issues that have hindered the real benefits of electronic health (eHealth) tools. As a component of eHealth systems, electronic health records (EHRs) play a fundamental role in patient management and effective medical care services. Thus, the adoption of EHRs in regions with a lack of infrastructure, untrained staff, and ill-equipped health care providers is an important task. However, the main barrier to adopting EHR software in low- and middle-income countries is the cost of its purchase and maintenance, which highlights the open-source approach as a good solution for these underserved areas. OBJECTIVE: The aim of this study was to conduct a systematic review of open-source EHR systems based on the requirements and limitations of low-resource settings. METHODS: First, we reviewed existing literature on the comparison of available open-source solutions. In close collaboration with the University of Gondar Hospital, Ethiopia, we identified common limitations in poor resource environments and also the main requirements that EHRs should support. Then, we extensively evaluated the current open-source EHR solutions, discussing their strengths and weaknesses, and their appropriateness to fulfill a predefined set of features relevant for low-resource settings. RESULTS: The evaluation methodology allowed assessment of several key aspects of available solutions that are as follows: (1) integrated applications, (2) configurable reports, (3) custom reports, (4) custom forms, (5) interoperability, (6) coding systems, (7) authentication methods, (8) patient portal, (9) access control model, (10) cryptographic features, (11) flexible data model, (12) offline support, (13) native client, (14) Web client,(15) other clients, (16) code-based language, (17) development activity, (18) modularity, (19) user interface, (20) community support, and (21) customization. The quality of each feature is discussed for each of the evaluated solutions and a final comparison is presented. CONCLUSIONS: There is a clear demand for open-source, reliable, and flexible EHR systems in low-resource settings. In this study, we have evaluated and compared five open-source EHR systems following a multidimensional methodology that can provide informed recommendations to other implementers, developers, and health care professionals. We hope that the results of this comparison can guide decision making when needing to adopt, install, and maintain an open-source EHR solution in low-resource settings.

RESUMEN

INTRODUCTION: Community health volunteers (CHVs) play an integral role in primary healthcare. Several countries rely on CHV programs as a major element in improving access to care and attaining universal health coverage. However, their performance has been heterogeneous and at times context-specific, and influenced by multiple factors. We describe the socio-demographic and workplace characteristics affecting CHVs' performance in a public health program in rural western Uganda. METHODS: This was a cross-sectional study based on routine program data of CHVs serving the catchment of Bwindi Community Hospital, Kanungu District, South Western Uganda, in 2014 and 2015. Information was collected on individual socio-demographic and workplace characteristics of the CHVs. To assess their work output, we defined study-specific targets in terms of attendance at monthly CHVs' meetings with community health nurses, households followed-up and reported, children screened for malnutrition, immunization coverage, and health facility deliveries. Frequencies and proportions are reported for characteristics and outputs and odds ratios for study-specific factors associated with overall performance. RESULTS: Of the 508 CHVs, 65% were women, 48% were aged 35 years and below, and 37% took care of more than the recommended 20-30 households. Seventy-eight percent of the CHVs had ≥80% of pregnant women under their care delivering in health units, 71% had ≥95% of the children on schedule for routine immunization, while 27% screened ≥75% of the children under 5 years for malnutrition. More refresher trainings was associated with better overall performance [adjusted odds ratio (aOR): 12.2, 95% confidence interval (CI): 1.6-93.6, P = 0.02] while overseeing more than the recommended 20-30 households reduced overall performance (aOR: 0.6, 95% CI: 0.4-0.9, P = 0.02). CONCLUSION: Being in-charge of more than the recommended households was associated with reduced performance of CHVs, while more refresher trainings were associated with improved performance. If the CHVs are to remain a strategic pillar in universal health coverage, it is imperative to address those factors known to impact on their performance.

RESUMEN

BACKGROUND: Telemedicine is a way to support physicians working in resource-poor settings, providing remote consultations and continuing medical education on HIV/AIDS care. METHODS: A hybrid E-mail/web support telemedicine service was created in 2003 at the Institute of Tropical Medicine, Antwerp, Belgium, with a discussion forum hosting more than 170 healthcare professionals from 40 different countries, generally resource constrained. Interesting posts and recurring questions from this discussion forum have been elaborated as case studies or frequently asked questions, available on the website for consultation. Education and support are also provided through interactive quizzes, user-friendly guidelines, and policy documents with a particular focus on HIV/AIDS care in developing countries. RESULTS: From April 2003 to March 2005, 342 questions were sent from over 17 countries in Africa, Asia, and South America. The vast majority of these questions (93%) were patient-oriented, with only 7% being general questions. Of the patient-oriented questions, 49% were related to antiretroviral therapy, and 44% were related to the diagnosis and treatment of opportunistic infections. CONCLUSIONS: Telemedicine is a cheap and effective method of providing clinical support and continuing education to healthcare workers treating HIV-positive patients in resource-poor settings.

RESUMEN

The introduction of highly active antiretroviral therapy (HAART) has changed the natural history of AIDS-associated Kaposi's sarcoma (KS). Although the use of HAART remains limited in low-resource settings, there are global initiatives to make these drugs available to several millions of HIV-infected persons. While there are multiple reports of KS regression during HAART with or without chemotherapy, there is little documentation on KS management in resource-limited settings. In this paper we review current KS treatments available worldwide and discuss the implications of the increased access to antiretrovirals for KS treatment strategies in resource-limited settings.
