acriflavine and elliptinium

We detected in 1989, with the inhibitor test of proviral insertion into c-erb B erythroblastosis, two retrovirus integrase inhibitors: hydroxy-methyl-ellipticine and acriflavine. They have been used for ten years in AIDS patients with high efficacy and no toxicity. Since vitamin B12 and cobalt, which it contains, have been detected as HIV1-integrase inhibitors by an in-vitro test, we have also used vitamin B12 (combined with folic acid), whose clinical action has been remarkable. Ten or so other compounds have been detected by such in-vitro tests, among which there are many compounds (such as flavones) which are used in many conditions and are not toxic.

Two virostatics which we discovered in 1990, acriflavine (ACF) and hydroxy-methyl-ellipticine (HEL) and shown active on HIV1 resistant to AZT have been introduced into combinations of four virostatics selected among ten available: themselves, plus zidovudine, zalcitabine, didanosine, lamivudine, stavudine, saquinavir, ritonavir, indinavir, the combinations were applied in 3-week sequences, differing from each other by drug rotation. Those which contained ACF may have more often a CD34 decrease than those containing neither ACF nor HEL, and they present more often a CD4 increase. No significant difference as far as side effects or beneficial effects could be detected after 18 months to 6 years, between sequences containing ACF or HEL or both, and sequences not containing any one of them.

To present the 4 to 9 years (median: 6 years) treatment follow up of 10 HIV1-AIDS patients, 9 at AIDS and 1 at A3 stages.. We have applied from 1992 to 1994, AZT combined with 2 integrase inhibitors, acriflavine and hydroxy-methyl-ellipticine. We could shift, in 1994, to combinations of 3 drugs including two more retrotranscriptase inhibitors (RTI), ddI and ddC, and, after 1995, to combinations of 4 drugs including also two other RTI, d4T and 3TC, and 3 protease inhibitors (PI), indinavir, ritonavir, and saquinavir. In 1998, as cobalamine was shown by an in vitro test, to act as integrase inhibitor, vitamin B12 was added in cycles of various lengths. Every three weeks, not only the investigations were repeated, but the virostatics were changed.. No grade 2 virostatics toxicity has been registered. The viral loads (VL) decreased according to exponential curves. Their initial parts obeyed first order kinetics. The second parts were and still are asymptotic. The first parts could be rectilinear or sinuous. The sinuosities were associated to cofactors present before treatment (chimerism, UV irradiation, hepatitis C or B and C, brain toxoplasmosis). The asymptotic parts, whose VL were below PCR detectable levels, presented discrete, reversible HIV1 rebounds, associated to other cofactors (such as herpes zoster, herpes 6, CMV, flat condyloma, and influenza). Among immunologic parameters, the monocyte and CTL numbers increased and presented, during the rapidly decreasing part of VL curve, a significant inverse correlation with it. Neither CD4+ nor suppressor T-cell (STC) numbers presented such correlation. Near 100 % of CTL were CD28+. Later, vitamin B12 applications increased monocyte and CD28+ CTL numbers, and appeared to reinforce VL stabilization.. The combinations of inhibitors affecting 3 retrovirus targets, retrotranscriptase, integrase, and protease have given to 10 out of 10 AIDS patients survivals varying today between 4 to 9 years, in excellent conditions. The UVA-pretreated patient is the only one presenting a not maximally reduced asymptotic VL, while his CD4+ and STC have been absent for 8 years. Other patient VL regressed exponentially to become asymptotic, below PCR detectable levels.
