[Clinical research of pasinizid on retreated sputum positive pulmonary tuberculosis in senilities]

Abstract

Objective: To observe and evaluate the effect and safety of pasinizid on treatment of the senile pulmonary tuberculosis with bacteriological positive.

Methods: 115 cases of the senile pulmonary tuberculosis with bacteriological positive were divided into therapy group(group A) and control group(group B1 and B2) randomly. Chemotherapy regimen: group A were treated by 3DZL2E/5DL2E mainly composed of pasinizid; group B1 were treated by 3HPZL2/5HL2E(abbreviated HP regimen); group B2 were treated by 3DZL2E/5DL2E(abbreviated SH regimen).

Results: When the chemotherapy was over, the sputum negative conversion rates were 92%, 72%, 71% in group A, group B1 and group B2 respectively. The conversion rate in group A was significantly higher than that in group B1 and group B2 (P < 0.05); focal absorption rates were 75%, 50%, 50% respectively, while the vanishing rates of cavity were 85%, 46%, 50% respectively. The rate in group A was significantly higher than that in group B1 and B2(P < 0.05); Rates of side effects were 17%, 58%, 18% respectively. The rates in group A and group B2 were apparently lower than that in group B1(P < 0.01). Bacteriological relapse rate of 2 years were 5%, 19%, 18%, respectively. The rate in group A was lower than that in group B1 and B2 (P < 0.01).

Conclusions: The effect of pasinizid on senile retreated sputum positive pulmonary tuberculosis was better than HP and SH regimen. Due to its lower rates of side effects, it is recommended for clinical usage.
