[CLINICAL EFFECTS OF INTRAVENOUSLY ADMINISTERED LEVOFLOXACIN IN PATIENTS WITH PULMONARY TUBERCULOSIS: A RETROSPECTIVE...

Our aim was to investigate the clini- cal effects of levofloxacin (LVFX) administered intravenously to patients with pulmonary tuberculosis.

We studied 65 patients hospitalized at The National Hospital Organization Tokyo National Hospital between January 2010 and December 2012. The patients did not have human immunodeficiency virus (HIV) infection, and received anti-tuberculous drugs intravenously due to the inability to receive drugs orally.

Twenty-seven patients were intravenously treated with isoniazid (INH), streptomycin (SM) and LVFX (HLS), and 38 patients were treated with INH and SM (HS). For both groups, mean age was very high (80.6±15.0 years, HLS group; 81.0± 12.1 years, HS group) and serum albumin levels were low (2.0 ± 0.62 mg/dl and 2.1 ± 0.42 mg/dl, respectively). Most patients were administered oxygen (81.5%, HLS; 78.9 %, HS). In radiological findings, most patients had bilateral (92.6%, HLS; 92.1%, HS) and widely spread (55.6%, HLS; 57.9%, HS) shadows. No significant differences were found between both groups in terms of the above data, except for sex. Almost 70% of all patients died; 51.9% of patients in the HLS group and 50.0% of those in the HS group died of tuberculosis, while 18.5% of patients in the HLS group and 18.4% of those in the HS group died of the other diseases. There were no significant differences in the causes of death and the survival rates of both groups.

Patients with pulmonary tuberculosis who were administered intravenous drugs were elderly and in poor general health. As such, mortality of these patients was very high. In this study, no clinical effects were found in the patients administered intravenous LVFX with INH and SM compared with patients treated with INH and SM.
