Cohort of HIV Associated Lymphomas

2014-08-27 03:12:09 | BioPortfolio


The incidence of lymphomas is increased among HIV infected patients. In 70 % of cases, those are Non Hodgkin's lymphomas (NHL) and Hodgkin lymphomas (HL) in 30% of cases. In France, their incidence is estimated to 100 cases per year (data from the "Base de données Hospitalière Française sur l'Infection à VIH" (FHDH)). The main mechanisms involved in lymphomagenesis are immune dysfunction, involvement of oncogenic viruses (Epstein-Barr (EBV) and HHV8) and molecular oncogenic events. A better understanding of these different pathways, give the possibility to design specific treatments. The treatment of these lymphomas is not standardized. A prospective study of patients with HIV associated lymphoid malignancies is an innovating tool to answer epidemiological, physiopathological and therapeutic questions. We propose a prospective multicentric study of these patients.

The main objectives of this prospective study are to:

- evaluate the incidence, characterise clinically and histologically NHL and HL cases associated to HIV

- perform an observational study of the treatment and outcome of these patients out of the context of clinical trials,

- study the differentiation and activation of B-cell populations,

- better understand the role of specific T cell responses in the control of EBV infection,

- allow other biological studies from the ANRS group " Lymphome et VIH ".

The recruitment of 80 cases per year is expected. The length of inclusions is 5 years. The follow-up will be of 5 years. Clinical, pathological and biological data at diagnosis and during follow-up will be collected. This will allow characterizing the lymphoma, the HIV infection, the antitumoral treatments and the outcome of lymphoma. Biological samples will be centralized to collect cell, DNA, RNA, plasma, serum and tumour collections (Y.Taoufik, M.Raphael* ). To better understand the EBV infection and lymphomagenesis in HIV infection, we propose to follow the viral load and the molecular characteristics of EBV in PBMC, plasma and tumour (P.Morand* , V.Boyer* ), to investigate the EBV-T cell responses (G.Carcelain) and the presence and reactivation of EBV in peripheral B cells (C.Amiel* , JC Nicolas) and in tumoral samples (M.Raphael* , I.Joab* ). The other mechanisms of lymphomagenesis in HIV infection will be studied by the analysis of the sub-populations of B-cells in terms of activation and differentiation (Y.Taoufik) and by the characterization of MSI tumours (A.Duval).

Medical and Biotech [MESH] Definitions

Infection by a variety of fungi, usually through four possible mechanisms: superficial infection producing conjunctivitis, keratitis, or lacrimal obstruction; extension of infection from neighboring structures - skin, paranasal sinuses, nasopharynx; direct introduction during surgery or accidental penetrating trauma; or via the blood or lymphatic routes in patients with underlying mycoses.

A nontuberculous infection when occurring in humans. It is characterized by pulmonary disease, lymphadenitis in children, and systemic disease in AIDS patients. Mycobacterium avium-intracellulare infection of birds and swine results in tuberculosis.

Infection involving the tissues or organs in the PELVIS.

Infection in humans and animals caused by fungi in the class Zygomycetes. It includes MUCORMYCOSIS and entomophthoramycosis. The latter is a tropical infection of subcutaneous tissue or paranasal sinuses caused by fungi in the order Entomophthorales. Phycomycosis, closely related to zygomycosis, describes infection with members of Phycomycetes, an obsolete classification.

An infection at a specific location that may spread to another region of the body.
