Post-kala-azar dermal leishmaniasis (PKDL) is rarely reported in South America. In spite of the fact that there are many reports about the association of visceral leishmaniasis and AIDS, PKDL is very uncommon in HIV-positive patients, and so far only four cases have been documented in the literature. We present another case with unusual clinicopathological aspects. The patient, a 28-year-old male, from Salvador, Bahia (an endemic area) presented with clinical manifestations of visceral leishmaniasis three years after the diagnosis of AIDS. During treatment for visceral leishmaniasis he developed disseminated miliary papules. Microscopically, the skin biopsy showed a "saw-tooth" pattern with a lichenoid mononuclear infiltrate simulating lichen planus. The histopathological diagnosis was achieved through the finding of amastigotes. The authors discuss the clinicopathological aspects of this case based on a review of the specific literature.
INTRODUCTION: Directly observed therapy programs developed for tuberculosis (TB) have been suggested as a model for the provision of HIV medications in resource-poor countries in order to ensure adherence and prevent drug resistance. METHODS: Opinions were formed based on a review of scientific literature regarding the effectiveness of witnessed dosing in directly observed TB therapy programs, adherence to HIV antiretroviral therapy in resource-rich and resource-poor settings, relationship between adherence and HIV antiretroviral drug resistance, HIV viral load and risk of HIV transmission, and stigmatization concerns related to HIV and TB in resource-poor settings. RESULTS/CONCLUSIONS: We suggest that the enthusiasm for HIV directly observed therapy programs is premature based on: equivocal evidence that witnessed dosing is superior to self administered therapy; mistaken assumptions that resource-poor countries are a 'special case' with respect to adherence; possible paradoxical impact of good adherence on HIV drug resistance; unproven efficacy of antiretroviral therapy in preventing HIV transmission; and potential stigmatization of daily antiretroviral dosing.
