Study in acute leukemia neutropenia in patients with the clinical application of quinolones in prevention of infection
Objective To investigate the clinical benefits and the impacts on distribution and antibiotic resistance of pathogenic bacterium associated with fluoroquinolone prophylaxis during neutropenia in patients with acute leukemia.MethodsA total of 62 infection episodes occurred in patients with acute leukemia were retrospectively analyzed from October 2013 to October 2015.The patients admitted in ward A (group A,n=31) received Cephalosporin drugs as contrast, and received quinolones in ward B (group B,n=31).ResultsTo observe the implementation of quinolones in treatment of patients, the bacteria decreased significantly, the Klebsiella pneumoniae was the most common, but compared with the control group, there are still differences (P<0.05, and the observation group of patients with oral ulcer infection rate was 9.68%, upper respiratory tract infection rate was 6.45%, the infection rate of lung 6.45%, the digestive tract infection rate was 6.45%, the infection rate was 3.23%, perianal skin infection rate was 3.23%, the infection rate was 3.23%, which is significantly lower than the control group (P<0.05, and the observation group of patients with severe neutropenia, duration of neutropenia lack degree is significantly better than the control group (P<0.05).ConclusionThe fluoroquinolone prophylaxis induces diminishing proportion of normal flora and increasing frequency of Escherichia coli in severely neutropenic patients with acute leukemia,may not influence the distribution of other bacteria.The susceptility of main pathogens may not be affected by antibiotic prophylaxis.The fluoroquinolone don't decrease the incidence of septicemia and infection in gastrointestinal tract.Our data suggest that more prudent use of antibiotic prophylaxis may be reasonable even in patients at high-risk for developing infection.
