Tang Herb and antiviral drugs have their own advantages respectively.Antiviral drugs used in combination with Tang Herb can increase the efficacy and reduce toxicity.But this kind of use must be under the guidance of doctors,and comply with the rule:taking antiviral drugs about an hour before Tang Herb.
Randomized controlled double-blind multicentric clinical study was carried out to evaluate the efficacy and safety of Tang Herb for HIV/AIDS treatment. The following were the results.
1.Absolute CD4 cell count:
After a treatment course of 6 month, a remarkable raise of CD4 cell count was observed in the Tang Herb treatment group, while in the placebo group CD4 cell count decreased. Statistical significance was found between the two groups. Further data analysis showed in ITT(intent to treatment) population, the average of CD4 cell count of treatment group increased by 69.32cells/ml, while in placebo group the number droped down by 24.56cells/ml. For PP(per-protocol) population, the average of CD4 cell count of treatment group increased by 71.64cells/ml, while in placebo group the number decreased by 37.38cells/ml. The above results showed an obvious advantage of Tang Herb over placebo.
Among ITT population 50.57% patients in treatment group was seen a more than 30% raise of CD4 cell count, which means the effective rate is 50.57％; For PP population, the number is 51.81%. Again the advantage of Tang Herb over placebo was obvious. According to the center-layered CMH test, difference between two groups has statistical significance（P=0.000）, the conclusions were the same when considering ITT and PP population respectively.
The efficacy of Tang Herb was evaluated at the end of treatment course with CD4 cell count as index, HIV-infectors and AIDS patients were analyzed respectively: For the HIV-infectors, the total effective rate of the treatment group was much higher than that of the placebo. Center-layered CMH test showed a difference of CD4 cell count between the Tang Herb group and the placebo group（PITT =0.00）, and the results from ITT and PP population were consistent. For the AIDS patients, the total effective rate of the treatment was much higher than that of the placebo. Center-layered CMH test showed a statistically significant difference of CD4 cell count between the Tang Herb group and the placebo group（Ppp =0.011）, and the results from ITT and PP population were consistent.
2. HIV virus load (log)
After a treatment course of 6 month, patients in the Tang Herb group maintained the virus load, while patients in placebo group experienced virus load increase. The change of virus load before and after treatment was statistically significant（PITT =0.005, Ppp=0.000）. For ITT population, virus load in the Tang Herb group declined 0.05, while in placebo group it increased 0.21. For PP population, virus load in the Tang Herb group declined 0.05, while in placebo group it increased 0.29. Covariance analysis showed no statistical significance (PITT=0.303; Ppp=0.121) as far as interaction between centers and treatment groups was considered, which indicated clinical results from all the centers were consistent.
Statistical analysises were also conducted for HIV-infectorss and AIDS patients respectively: For HIV-infectors, difference of virus load between of two groups was observed statistically significant (PITT=0.037); For AIDS patients, statistical significance was also observed as to difference of the virus load (PITT=0.005). The advantage of Tang Herb over the placebo was obvious in both case.
3. Clinical Symptom Score
Clinical trials observed remarkable improvement on clinical symptoms such as diarrhea, fatigue, alopecia and poor appetite as well as amelioration on motion functional classification. The improvement was found statistically significant between treatment group and placebo group(P=0.000). The advantage of Tang Herb over the placebo was obvious with respect to total clinical score, individual clinical score, and body weight.
4. Ratio between CD4 and CD8
The ratio of CD4 to CD8 was increased in the Tang Herb group while placebo group saw a decrease of the ratio. Calculation based on covariance analytical model indicated the difference statistically significantly between Tang Herb group and placebo group.
5. CD8 cell count
No statistical significance was found between the two groups.
Slight side effects occurred in isolated cases, including slight nausea, indigestion and slight insomnia. These unwanted symptoms disappeared soon without intervention and no treatment was interupted.
No adverse reaction against liver, kidney, heart and hematological system was observed after administration of Tang Herb for 6 months. The Tang Herb was well tolerable and no drug withdrawal was seen because of adverse reactions.
[Pharmacology and Toxicology]
In clinical trials Tang Herb is shown to be highly effective in inhibiting HIV and HCV replication in AIDS patients co-infected with HCV. Other effects exibited include decreasing β2 microglobulin in peripheral blood of HIV-infectors, promoting sceretion of Th1 cytokine and enhancing T cell function, which are favorable for virus replication control. Virus replication inhibition is observed in in vitro test as well.
Store in a dry place at a temperature below 20℃, keep away from light.
