Background: The occurrence of human immunodeficiency virus (HIV)-associated Hodgkin disease (HD) offers a unique opportunity to study the cause of HD and compare HIV-HD with the well-characterized HIV-non-Hodgkin lymphoma (NHL).
Methods: Eight patients with HIV-HD and 17 with HIV-NHL were treated.
Results: The complete remission (CR) rate in HIV-HD was 100% with mechlorethamine, vincristine, procarbazine, and prednisone or doxorubicin, bleomycin, vinblastine, and dacarbazine (median survival, > 38.0 months). HIV-NHL patients were treated with cyclophosphamide, doxorubicin, vincristine, and prednisone (CR, 80%; median survival, 13.0 +/- 1.3 months). Durable CR was achieved with one to six cycles of chemotherapy (median, 4). There were no late relapses. The difference between the survival rate associated with chemotherapy-treated HIV-HD and chemotherapy-treated HIV-NHL approached statistical significance (P = 0.06). Analysis indicated that all patients with HIV-HD (n = 8) may have acquired HIV through intravenous drug abuse (IVDA) compared with 1 of 17 patients with HIV-NHL (P = 0.0001). A combined analysis (metaanalysis) of 157 patients with chemotherapy-treated HIV-NHL and 51 with chemotherapy-treated HIV-HD confirmed the significantly better survival of those with HIV-HD (P < 0.0001).
Conclusions: Standard combination chemotherapy, truncated as necessary, offers survival outcomes that are at least equivalent and, perhaps, superior to previously published experimental approaches for HIV-NHL and HIV-HD. HIV-HD has a significantly better prognosis than HIV-NHL and is associated with IVDA. These data suggest that the etiologic agents of HIV-HD and HIV-NHL may be transmissible, identifiable, and unique.

Children of a syndemic: co-occurring and mutually reinforcing adverse child health exposures in a prospective cohort of HIV-affected mother-infant dyads in Cape Town, South Africa.

Introduction: Several HIV-related syndemics have been described among adults. We investigated syndemic vulnerability to hazardous drinking (HD), intimate partner violence (IPV) and household food insecurity (HFIS) in breastfed children born without HIV in urban South Africa. We compared those who were perinatally HIV exposed (CHEU) to those who were not (CHU), under conditions of universal maternal antiretroviral therapy (ART) and breastfeeding.

NLRP3 inflammasome plays a key role in dendritic cells (DC) activation in response to vaccine adjuvants, however we previously showed that it is not properly activated in DC from HIV-infected patients (HIV-DC), explaining, at least in part, the poor response to immunization of these patients. Taking in account that several cytoplasmic receptors are able to activate inflammasome, and that bacterial components are considered as a novel and efficient adjuvant, we postulated that bacterial flagellin (FLG), a natural ligand of NAIP/NLRC4 inflammasome, could rescue the activation of the complex in HIV-DC. Demonstrate that FLG is able to activate monocyte-derived dendritic cells from HIV-infected individuals better than LPS, and to what extent the entity of inflammasome activation differs between DC from HIV-infected patients and healthy donors.

Background: The purpose of the study was to evaluate the outcome of Hodgkin's disease (HD) in patients infected with the human immunodeficiency virus (HIV) with respect to the use of highly active antiretroviral therapy (HAART).
Materials And Methods: This cohort study included patients with HIV-HD diagnosed from June 1984 to February 2004. Patients treated in the pre-HAART era (1984-1996) were compared with those belonging to the HAART era (1997-2004).
