Abstract:

The therapy of AIDS and cancer rarely used single drugs, but rather have used two or more drug combinations. Drug combination may provide benefits of synergistic therapeutic effect, as well as reduced toxicity, minimized or delayed development of drug resistance, or allowed attacking multiple receptor or etiological targets. The important basic requirments for these aims are: i) Definition of synergism and its quantitative determination using the combination Index (CI<1); ii) Simple and efficient experiment design using small number of data points and small number patients in phase-I clinical trial design using the mass-action law based "minimum of two-data point theory" for dose and effect dynamics ; iii) The theoretical basis for the Combination Index for 3 or more drugs combinations using the "Polygonogram". The original CI equation, theory, algorithm, and computerized simulation of synergism and antagonisn were presented in Chou TC & Talalay. Adv. Enz. Regul 22:27-55, 1984, cited 4,357 times in 850 different journals); in Chou TC. Pharmacol Rev 58:621-681, 2006 (cited 1,298 times in 342 journals); and in Chou TC. Integrative Biol. 3:548-559, 2011 (featured on the front-cover of the May issue, published by RSC Cambridge, UK). Questions to be asked are: How to assess combo synergy quantitatively for 2 or more drugs?; Are the Combos on the market the best in synergy?; Do peer reviewers, journal editors and governmental regulatory agencies really understand "What is synergy?. These issues will be discussed and the answers will be provided.

Biography:

I have a background in Pediatrics and Pediatric Infectious Diseases, including Board Certification and recertification, as well as expertise in evaluating immunities to vaccine preventable infections in HIV-infected and HIV-exposed children. My research in this area was initiated as a fellow at Mount Sinai Medical Center, New York, where I evaluated the immunogenicity to the hepatitis B vaccine in HIV-infected children. Subsequently, I was able to successfully develop and conduct an RC1 research project evaluating serotype specific antibodies to S pneumoniae in US-born versus Hispanic pregnant women and cord blood samples of their infants. This resulted in a publication in the May-June 2012 issue of JNMA.

Abstract:

Immunity to varicella and measles have not been compared in HIV seropositive and rnseronegative pregnant women and their infants. Antibody levels to varicella and measles were rnevaluated in 14 HIV seropositive and 34 seronegative pregnant women, 14 HIV exposed and 26 rnun-exposed cord bloods, and followed-up prospectively in 23 HIV exposed and unexposed infants rnaround 3- 7 months of age by ELISA (99 samples) and by EIA (13 samples) for measles and byrnimmunofluorescence (IFA) for varicella. Correlates of immunity were defined as antibody levels rnmeasles (> 1.09 OD ratio or EIA) and >1:8 IFA for varicella. Antibody levels were correlated with rnT cell counts in HIV seropositive mothers. Mean (range) ages of women at time of serologic rntests were 27 (18-40), and 25 (15-41) years for HIV and control groups, respectively. Antibody rnlevels to measles were significantly (P= 0.04) lower in cord bloods of HIV exposed infants rncompared to the controls. T cell counts were lower in HIV seropositive women non-immune rn(268/mm3) to measles compared to those immune (618/mm3), but insignificantly (P= 0.07).rnImmunity to measles and varicella as recognized by antibody levels declined significantly in rnboth HIV exposed and unexposed infants by 3- 7 months of age.rn
