Immunogenicity and safety of an inactivated hepatitis A vaccine in anti-HIV positive and negative homosexual men.
1995
The immunogenicity, reactogenicity, and safety of an inactivated hepatitis A vaccine were assessed in anti-HIV positive homosexual men. Fourteen anti-HIV positive (group 1) and 20 anti-HIV negative (group 2) men received vaccine (containing 720 ELISA units of hepatitis A antigen per dose) intramuscularly at 0, 1, and 6 months. Twelve unvaccinated anti-HIV positive men (group 3) were included as controls to evaluate disease progression. Seroconversion (anti-hepatitis V virus (HAV ⩾20 mlU/ml) was higher in group 2 than group 1 at months 2 (100% vs. 73%) and 7 (l00%vs. 77%). Group 2 had higher antibody titres than group 1 at months 1 (201 vs. 92 mlU/ml) and 7 (1, 687 vs. 636 mlU/ml). The decli…
Bone Marrow Findings in Multicentric Castleman Disease in HIV-negative Patients
2007
Because bone marrow histology in multicentric Castleman disease in human immunodeficiency virus-negative patients is not well reported, we investigated sequential bone marrow biopsies of 3 affected human immunodeficiency virus-negative patients, of which one was human herpes virus 8 (HHV8)-positive. The histologic evaluation of the bone marrow revealed lymphoid follicles with regressed germinal centers in 1 patient. Another patient showed tumorlike but bland polyclonal plasmacytosis with large perivascular plasma cell clusters. The HHV8-positive patient revealed interstitial HHV8-positive cells accompanied by a mild plasmacytosis. The atypical lymphoid follicles could be regarded as a bone …
Therapeutic management and evolution of chronic hepatitis B: does HIV still have an impact? The EPIB 2012 study
2015
EA Pôle MERS Hors CT hors EJ; International audience; Background & Aims: To compare the management of chronic hepatitis B (CHB) and its evolution over time in currently followed HIV-positive and HIV-negative patients. Methods: A total of 709 consecutive patients with past or present positive HBs antigenemia seen in October 2012 in 19 French participating centres were included. The data were retrospectively collected from the first visit onwards through standardized questionnaires. Results: Chronic hepatitis B was less often assessed in the 299 HIV-positive patients, who were older, more likely to be male, excessive alcohol drinkers and HBe antigen-, HCV- and HDV-positive. They were also fol…
Serum malondialdehyde in HIV-seropositive children negatively correlates with CD4+ lymphocytes count.
1998
Human immunodeficiency virus (HIV) infection is associated with oxidative stress as it has been demonstrated in adult-seropositive individuals. We show in this study that serum malondialdehyde (MDA) concentration of HIV-infected children was significantly higher than in control children. A negative correlation (r = -0.515) was found in HIV-infected children between their CD4+ lymphocyte count, and MDA concentration but not with serum antioxidant status. The increase of MDA concentration in HIV-seropositive children confirms the involvement of oxidative stress in the pathophysiology of this infection also in childhood. Because of the importance of oxidative stress and antioxidants for HIV vi…
Mediastinal syndrome from plasmablastic lymphoma in human immunodeficiency virus and human herpes virus 8 negative patient with polycythemia vera: a …
2017
Background: Plasmoblastic lymphoma is a rare and aggressive subtype of diffuse large B cell lymphoma, which occurs usually in the jaw of immunocompromised subjects. Case presentation: We describe the occurrence of plasmoblastic lymphoma in the mediastinum and chest wall skin of an human immunodeficiency virus-negative 63-year-old Caucasian man who had had polycytemia vera 7 years before. At admission, the patient showed a superior vena cava syndrome, with persistent dyspnoea, cough, and distension of the jugular veins. Imaging findings showed a 9.7 × 8 × 5.7 cm mediastinal mass. A chest wall neoformation biopsy and ultrasound-guided fine-needle aspiration biopsy of the mediastinal mass allo…
