ABSTRACT: INTRODUCTION: Lesotho has the third highest HIV prevalence in the world (an adult prevalence of 23.2%). Despite a lack of resources for health, the country has implemented state-of-the-art antiretroviral treatment guidelines, including early initiation of treatment (<350 cells/mm3), tenofovir in first line, and nurse-initiated and managed HIV care, including antiretroviral therapy (ART), at primary health care level. PROGRAMME APPROACH: We describe two-year outcomes of a decentralized HIV/AIDS care programme run by Doctors Without Borders/Médecins Sans Frontières, the Ministry of Health and Social Welfare, and the Christian Health Association of Lesotho in Scott catchment area, a rural health zone covering 14 clinics and one district hospital. Outcome data are described through a retrospective cohort analysis of adults and children initiated on ART between 2006 and 2008. DISCUSSION AND EVALUATION: Overall, 13,243 people have been enrolled in HIV care (5% children), and 5376 initiated on ART (6.5% children), 80% at primary care level. Between 2006 and 2008, annual enrolment more than doubled for adults and children, with no major external increase in human resources. The proportion of adults arriving sick (CD4 <50 cells/mm3) decreased from 22.2% in 2006 to 11.9% in 2008. Twelve-month outcomes are satisfactory in terms of mortality (11% for adults; 9% for children) and loss to follow up (8.8%). At 12 months, 80% of adults and 89% of children were alive and in care, meaning they were still taking their treatment; at 24 months, 77% of adults remained in care. CONCLUSION: Despite major resource constraints, Lesotho is comparing favourably with its better resourced neighbour, using the latest international ART recommendations. The successful two-year outcomes are further evidence that HIV/AIDS care and treatment can be provided effectively at the primary care level. The programme highlights how improving HIV care strengthened the primary health care system, and validates several critical areas for task shifting that are being considered by other countries in the region, including nurse-driven ART for adults and children, and lay counsellor-supported testing and counselling, adherence and case management.

BACKGROUND
The provision of antiretroviral therapy (ART) to migrant populations raises particular challenges with respect to ensuring adequate treatment support, adherence, and retention in care. We assessed rates of loss to follow-up for migrant workers compared with non-migrant workers in a routine treatment programme in Morjia, Lesotho.
DESIGN
All adult patients (≥18 years) initiating ART between January 1, 2008, and December 31, 2008, and followed up until the end of 2009, were included in the study. We described rates of loss to follow-up according to migrant status by Kaplan-Meier estimates, and used Poisson regression to model associations between migrant status and loss to follow-up controlling for potential confounders identified a priori.
RESULTS
Our cohort comprised 1185 people, among whom 12% (148) were migrant workers. Among the migrant workers, median age was 36.1 (29.6-45.9) and the majority (55%) were male. We found no statistically significant differences between baseline characteristics and migrant status. Rates of lost to follow up were similar between migrants and non-migrants in the first 3 months but differences increased thereafter. Between 3 and 6 months after initiating antiretroviral therapy, migrants had a 2.78-fold increased rate of defaulting (95%CI 1.15-6.73); between 6 and 12 months the rate was 2.36 times greater (95%CI 1.18-4.73), whereas after 1 year the rate was 6.69 times greater (95%CI 3.18-14.09).
CONCLUSIONS
Our study highlights the need for programme implementers to take into account the specific challenges that may influence continuity of antiretroviral treatment and care for migrant populations.

BACKGROUND
The latest World Health Organization guidelines recommend replacing stavudine with tenofovir or zidovudine in first-line antiretroviral therapy in resource-limited settings. We report on outcomes and toxicities among patients on these different regimens in a routine treatment cohort in Lesotho.
METHODS
All adult patients initiating antiretroviral therapy from January 1, 2008, to December 31, 2008, were included in the analysis and followed until December 31, 2009. Choice of regimen was determined by clinical criteria.
RESULTS
Of 1124 patient records analyzed, median age was 39 years, and the majority (67.7%) were women. Five hundred eighty-seven patients were started on tenofovir, 255 on zidovudine, and 282 on stavudine. Patients on zidovudine were more than twice as likely to experience a toxicity-driven regimen substitution compared with tenofovir (adjusted hazard ratio: 2.32, 95% confidence interval: 1.23 to 4.40); for patients on stavudine, the risk of a toxicity-driven regimen switch was almost 6 times higher than tenofovir (adjusted hazard ratio: 5.43, 95% confidence interval: 3.31 to 8.91).
CONCLUSIONS
Our findings support the latest World Health Organization Guidelines, in particular the adoption of tenofovir in first line, given the advantages in terms of tolerability and availability as a once-daily formulation.
