In May 2011, the Brazilian Ministry of Health announced the distribution of the first batch of locally produced generic tenofovir disoproxil fumarate (TDF) to support its program of universal and free access for the treatment of HIV/AIDS. The inclusion of TDF in the public health program illustrates what has been considered the 'Brazilian model' of HIV/AIDS response, as it illustrates the current phase of the Brazilian pharmaceutical economy. Brazil is known for having managed to control the expansion of HIV/AIDS through a unique initiative combining the public health and the industrial production of generics. But, if at first local manufacturers could freely copy ARVs and produce cheaper generic versions that were delivered to the Ministry of Health, since the country started to grant patents on drugs in 1996, the sustainability of this policy has been challenged by the high cost of patented second-line HIV/AIDS treatments. In order to assure continuity of the local production of ARVs, and keep the program of public health alive, Brazilians are now forced to deal with conflicts of drugs' intellectual property rights in order to open the path to generic production. This article aims to describe the experiences surrounding TDF in Brazil and the unprecedented conflicts and challenges it has brought for our different interviewees. Blurring the frontier between the public and the private, the TDF case was driven at the same time by an ethic of drug access and regulation of drug quality, which has inspired Brazilians to intervene and transform the world they live in.

A 45-year-old man, a case of acquired immunodeficiency syndrome, received a highly active antiretroviral therapy at the outpatient service for 4 years without regular follow-up. He experienced progressively blurred vision for 6 months and a cutaneous zoster on his back 3 months ago. He was diagnosed with progressive outer retinal necrosis by polymerase chain reaction-restriction fragment length polymorphism using an aqueous humor sample, which revealed an existence of varicella zoster virus. He was given a combination of systemic, intravitreal antiviral and a highly active antiretroviral therapy. Occlusive vasculitis, an unusual finding for progressive outer retinal necrosis, developed in both eyes 1 week after the secondary intravitreal injection. Unfortunately, his vision deteriorated to no light perception in both eyes within 2 weeks. Progressive outer retinal necrosis is characterized clinically as showing minimal or no inflammation in the aqueous and vitreous humors, absence of retinal vasculitis, and patches of yellowish spots located deep in the retina. Physicians should pay attention to this rare case of progressive outer retinal necrosis associated occlusive vasculitis with very poor prognosis in spite of aggressive treatment.

Varicella-zoster virus (VZV) has been known to cause various eye disorders in both immunocompetent and immunocompromised patients. We present a case of a forty-nine-year-old female patient with acquired immunodeficiency syndrome (AIDS) who presented with headache, fever, and blurred vision. Cerebrospinal fluid (CSF) analysis was consistent with VZV meningitis. Magnetic resonance imaging (MRI) of the brain showed enhancement of the right optic nerve indicative of optic neuritis. She responded well to acyclovir and steroids and discharged on the same. Four weeks after discharge, she presented with sudden onset blindness in the left eye. A cerebral angiogram revealed left retinal artery occlusion and was treated with tissue plasminogen activator (tPA). Funduscopic examination showed patchy areas of necrosis in the periphery which were rapidly progressive, diagnostic of posterior outer retinal necrosis (PORN). She was started on ganciclovir and cidofovir and experienced significant improvement in her visual acuity.
