Management and Prevention of Percutaneous Iliac Stent Infection: A Case Report.

A 52-year-old man was admitted in the emergency department for deteriorating mental status and suspicion of discitis. Computed tomography and positron emission tomography scan showed evidence of localized infection of the aortic bifurcation and blood cultures were positive for Staphylococcus aureus. Ten years ago, the patient underwent placement of covered metal stents on each common iliac artery due to arteritic stenosis.

Plasmablastic microlymphoma occurring in human herpesvirus 8 (HHV-8)-positive multicentric Castleman's disease and featuring a follicular growth pattern.

Plasmablastic microlymphoma (PML) is defined as the accumulation of monotypic but polyclonal plasmablasts in lymphoid tissues involved in human herpes virus 8 (HHV-8)-positive multicentric Castleman's disease (MCD). So far, the nature of this very rare condition remains poorly determined. In this study, we describe a human immunodeficiency virus (HIV)-seropositive patient who developed a PML in the setting of HHV-8-positive MCD.

Rising prevalence of HIV-1 non-B subtypes in Belgium: 1983-2001.

This study documented the HIV-1 subtype distribution in 2 Belgian hospitals and determined predictive demographics for non-B subtypes. Overall, subtype B was the most prevalent subtype in this population, followed by subtypes A and C. Several recombinants were detected, circulating recombinants as well as new ones.

Expression of the fibroblast/macrophage marker 1B10 by spindle cells in Kaposi's sarcoma lesions and by Kaposi's sarcoma-derived tumor cells.

Background: Kaposi's sarcoma (KS) is a tumor whose ontogenic origin remains a matter of contention. KS tissues are characterized by predominant expression of endothelial markers, while KS-derived cell cultures are usually characterized by expression of mesenchymal non-endothelial cell markers.

Aims: In order to clarify the ontogenic origin of KS cells, we investigated the expression of the fibroblast/macrophage marker 1B10 in KS tissues (AIDS-associated KS, n = 9; classic KS, n = 6; iatrogenic KS, n = 6) and in KS-derived cell cultures.

Desferrioxamine enhances AIDS-associated Kaposi's sarcoma tumor development in a xenograft model.

Iron is suspected to be involved in the induction and/or progression of various human tumors. More particularly, we have previously shown that iron may be involved in the pathogenesis of Kaposi's sarcoma (KS). We have also shown that the iron chelator desferrioxamine (DFO) has a potent anti-KS activity in vitro, suggesting that it may represent a potential therapeutic approach for the treatment of KS.

A clinically prognostic scoring system for patients receiving highly active antiretroviral therapy: results from the EuroSIDA study.

The risk of clinical progression for human immunodeficiency virus (HIV)-infected persons receiving treatment with highly active antiretroviral therapy (HAART) is poorly defined. From an inception cohort of 8457 HIV-infected persons, 2027 patients who started HAART during prospective follow-up were examined. Results were validated in another 2 groups of patients (n=1946 and n=1442).
