Objective: Inelaborate use of new quinolones with strong anti-tuberculosis (TB) activity leads to difficulty in diagnosis and more importantly, quinolone-resistant Mycobacterium tuberculosis. We aimed to determine the frequency of quinolone use in patients who were referred to our hospital for suspected TB and to evaluate the association between quinolone use and different clinical laboratory parameters.
Methods: Between November 15 and December 15, 2013, all patients who were admitted to the TB outpatient clinic with no previous diagnosis of TB were included in this study. Demographic and clinical laboratory findings and history of antibiotic use were recorded. Patients’ quinolone use were questioned by showing fluoroquinolone antibiotic boxes’ photographs available on the market. The departments of the doctors who prescribed quinolones were recorded.
Results: The mean age of 179 patients included in the study was 37±16 (15–89) years. Among these, 113 patients (63.1%) were male. Seventy five patients (41.9%) were diagnosed as tuberculosis according to the clinical-radiological and/or bacteriological findings. Of 179 patients, 58.1% (n=104) had been prescribed antibiotics for current complaints before referral to our clinic. Sixteen patients (15%) had been recommended fluoroquinolones. Fluoroquinolones were prescribed by seven internal medicine specialists, five pulmonologists, three emergency medicine specialists, and one family medicine practitioner. Among 16 fluoroquinolones prescribed, nine were moxifloxacin, four were levofloxacin, and three were gemifloxacin. Quinolone use revealed a significant inverse relationship only with the presence of hemoptysis (p=0.04).
Conclusion: Besides increased educational activities regarding the rational use of antibiotics in recent years, the quinolone group of antibiotics is still prescribed for suspected TB cases. To avoid quinolone-resistant M. tuberculosis strains, further education is required.
