Group1 included 23 patients with TB/TM and HIV co-infection treated with E and H i/v, while rifampicin and pyrazinamide were prescribed orally. The group 2 consisted of 31 patients–treated with 1st-line anti-TB drugs orally. Concentrations of H and E in blood serum were detected using a chromatographic method.Results: A significant improvement in clinical symptoms and X-ray signs in patients treated i/v with H and E was observed compared with the group 2. In addition,9(39.1±10.4%) patients died up to six months when H and E were prescribed i/v compared with 22(70.9±8.1%) in the group 2 (p<0.05).Conclusions: As a result of the i/v administration of H and E, the basic clinical symptoms and X-ray signs of TM in the examined patients were more likely to reverse compared with those who were administered anti-TB drugs orally.I/v H and E chemotherapy during the intensive phase reduces the mortality rate of patients compared with the oral administration of the drugs mentioned above.I/v H and E administration is accompanied by significantly higher mean serum concentrations of drugs.I/v H and E administration in patients with TM does not cause additional side effects compared with the group2.FootnotesCite this article as: European Respiratory Journal 2019; 54: Suppl. 63, PA5272.This is an ERS International Congress abstract.
