Rapid scale-up of antiretroviral treatment programmes is happening in Africa, driven by international advocacy and policy directives and supported by unprecedented donor funding and technical assistance. This welcome development offers hope to millions of HIV-infected Africans, among whom tuberculosis is the major cause of serious illness and death. ⋯ Many barriers exist, from drug interactions to historic differences in the way that tuberculosis and HIV are perceived, but failure to successfully integrate HIV and tuberculosis control will threaten the viability of both programmes. Here, we review tuberculosis epidemiology in Africa and policy implications of HIV/AIDS treatment scale-up.

Randomized Controlled Trial Multicenter Study
Azathioprine dosed by thiopurine methyltransferase activity for moderate-to-severe atopic eczema: a double-blind, randomised controlled trial.
Atopic eczema affects 1-2% of adults, and can cause considerable morbidity. We aimed to assess the safety and efficacy of azathioprine as systemic monotherapy for moderate-to-severe atopic eczema, and the therapeutic importance of the thiopurine methyltransferase (TPMT) polymorphism (a key determinant of azathioprine-induced myelotoxicity) by using TPMT enzyme activity to establish azathioprine dose. ⋯ Treatment with azathioprine as systemic monotherapy produces clinically relevant improvement in moderate-to-severe atopic eczema that remains active despite optimum therapy with topical corticosteriods. We believe the study of azathioprine as systemic monotherapy for atopic eczema has major advantages, which should allow clarification of the relation between azathioprine effectiveness and metabolite profiles in other inflammatory diseases.
