Ce congrès européen, dont les participants sont essentiellement des cliniciens s’élargit au fil des ans au reste du monde et a déplacé cette année plus de 3000 participants. Beaucoup de résultats ont été présentés mais sans aucune voie ouverte tant sur le vaccin que sur l’éradication. Beaucoup d’essais cliniques comparatifs et aussi de simplification des traitements, mais sans intérêt majeur si ce n’est une compétition stérile entre les laboratoires, les différentes combinaisons d’antiviraux n’ayant pas de différence très significative quant à leur efficacité. Beaucoup de communications sur les effets indésirables des différent antiviraux avec l’apparition inquiétante des désordres neuropsychiatrique (qui n’avaient donné lieu à AIDS 2008 à Mexico qu’à une seule communication Poster). Autre fait à noter, cette conférence est de plus en plus verrouillée par les firmes pharmaceutiques qui la sponsorisent. Pas une seule communication sur les traitements alternatifs/complémentaires (y compris celle que nous avions soumis sur l’intérêt de deux plantes de la savane africaine), n’a été retenue.

Parmi les communications orales, nous retiendrons la faisabilité de monothérapies avec Darunavir/ritonavir; Lopinavir/ritonavir; . Par contre le Raltegravir conduit à un échec en monothérapie.

INTRODUCTION

Canarypox virus based AIDS vaccine was stopped in USA (and also in France) after the occurrence of an acute myelitis case, suggesting that the species barrier between birds and humans (as for influenza and poliomyelitis virus) was broken by canarypox virus. In France, the vaccine did not contain canarypox virus but only lipopeptides, so the vaccination was retried after the verification of lipopeptides innocuity. Zagury D (1991) precedently had complications after vaccination with a vaccinia virus vector in HIV-1 patients, but this was forgotten: He reported cell immunotherapy with recombinant vaccinia that resulted in “wide necrosis” at the site of subcutaneous/intramuscular injections, resulting in death in 3 of 8 Aids patients; all 3 had CD4 counts less than 50 cells/mm3. Thus it seems that poxvirus family may represent a harmful family of viruses in AIDS patients.

In fact the acute myelitis observed with canarypox vaccine reminds the multiple sclerosis (MS) picture and discovery of anti-vaccinia virus antibodies in MS by various authors (Kempe CH, 1973; Thompson JA, 1975; Myamoto H, 1976).

INTRODUCTION.

In France, AIDS haemophiliacs and drug addicts and 600,000 patients were infected by HCV, with the risk of cirrhosis and cancer. This constitutes a major health problem. Interferon-alpha and ribavirin could resolve this problem only partially in about 6/10 cases.

No HCV vaccine is available to date.

In Egypt, an epidemics of hepatitis C spread after the mass campaign of emetin intravenous injections with contaminated syringues for bilharsiosis (Schistosomia Mansoni and Haematobium) (Franck C., 2000).

Background: In HIV patients, progressive multifocal leucoencephalopathy (PML) is characterized by an intense gliosis and caused by a polyomavirus (PV).Brain glioma are induced in newborn hamsters by PV. OHGAKI H (1998) found PV with a high frequency in human glioma. More worrying is the anti-poliomyelitis vaccine contamination by SV 40 in the 1950s., because authentic SV 40 was found in childhood brain tumors. An increase in neural tumors was reported in children born from mothers receiving this vaccine during pregnancy. PV large T (= Tumor) antigen also binds to anti-oncogens p53 and Rb.

Aids is characterized by the occurrence of severe atherosclerosis in very young patients. This prompted us to look for the physiopathology of atherosclerosis in this especially susceptible but unusual population. Our objective is to screen for viruses inducing atherosclerosis.

We looked on Marek's herpes virus (Fabricant C.G., 1978), which can induce in chicken coronary disease even with a diet without cholesterol. CMV is also a good candidate, as it enhances the recurrences of coronary stenosis after stent. Lastly, in transgenic mouse, phospholipase A2 is responsible of atherosclerosis (Ivandic B., 1999). By comparison of amino acid sequences, we found 3 significant homologies :

  1. Marek's herpes virus 132bp repeat (sequence LHTS... TICRNK FLCLLP) ...is a rabbit LDL cholesterol receptor ( repeat V)-like (CIHSSÉSLC-ss-CKNK... RQFVC-ss-CPVL) in tridimensional cysteine bridged [-ss-] structure.
  2. CMV TRL6 (sequence WKTV...DQWLCNVTGIGNAT) is a LDL related receptor-like. (WHSV...QWLCD).
  3. HIV-1 VIF protein has the tridimensionnal structure and active site residues (His, Ser) of a phospholipase A.

Conclusion:

These striking homologies between virus and cholesterol receptors, and between HIV-1 VIF and phospholipase A may explain the abnormal occurrence of severe atherosclerosis in such a young population as AIDS. Treatment must focus on anti-herpes virus drugs (and bee propolis, an antiviral natural product) as well as on VIF for a component of AIDS vaccine and anti-phospholipase drug.
