Abstract:
The mortality rate of febrile neutropenia (FN) has diminished steadily but remains significant. Overall mortality rates are 5% in patients with
solid tumors (1% in low-risk patients) and as high as 11% in some
hematological malignancies. Piperacillin/Tazobactam is a
β-lactam/β-lactamase inhibitor combination with a broad spectrum of
antibacterial activity against most Gram-positive, Gram-negative aerobic
bacteria and anaerobic bacteria. Piperacillin/Tazobactam is effective
and well tolerated in patients with febrile neutropenia. Guidelines for the Management of Febrile Neutropenia in Oncology Patients and the 2010 National Comprehensive Cancer Network (NCCN) Prevention and treatment for febrile neutropenia recommends as initial treatment in patients with FN who are at high risk of serious infections. In comparative clinical trials
against various other antibacterial regimens. Piperacillin/Tazobactam
has shown higher clinical success rates, particularly in the treatment
of patients with febrile neutropenia. Piperacillin/Tazobactam has shown
clinical as well as the economic advantages over other antibacterial
regimens in the treatment of febrile episodes in patients with neutropenia. It is likely to reduce overall
treatment costs of moderate to severe febrile neutropenia by increasing
initial treatment success thereby reducing the length of hospital stay
and the use of additional antibacterials. Present data regarding
clinical efficacy, safety and costs would support the use of
Piperacillin/Tazobactam as an empirical first-line option in moderate to
severe febrile episodes in patients with neutropenia.
Introduction:
Though there have been major advances in prevention and treatment of
febrile neutropenia (FN) febrile neutropenia still remains one of the
most feared complications of cancer chemotherapy.
It is a major cause of morbidity, healthcare resource use, and results
in delays and dose reductions in chemotherapy which compromise efficacy.
The mortality rate of febrile neutropenia (FN) has diminished steadily
but remains significant. Overall mortality rates are 5% in patients with
solid tumors (1% in low-risk patients) and as high as 11% in some
hematological malignancies.1 As such, febrile neutropenia (FN) requires
prompt treatment with Piperacillin -Tazobactam since it may be
associated with life-threatening infections. Piperacillin/Tazobactam is a
β-lactam/β-lactamase inhibitor combination with a broad spectrum of
antibacterial activity against most Gram-positive, Gram-negative aerobic
bacteria and anaerobic bacteria. Piperacillin / Tazobactam is effective
and well tolerated in patients with febrile neutropenia. Guidelines for the Management of Febrile Neutropenia in Oncology Patients and the 2010 National Comprehensive Cancer Network (NCCN) Prevention and treatment for febrile neutropenia recommends as initial treatment in patients with FN who are at high risk of serious infections. In comparative clinical trials
against various other antibacterial regimens, Piperacillin/Tazobactam
has shown higher clinical success rates, particularly in the treatment
of patients with febrile neutropenia. The studies which are supported to
the Piperacillin/Tazobactam in the management of Febrile Neutropenia
are explained in the table 1.2,3,4,5

Cohort Study of the Efficacy and Safety of Piperacillin/Tazobactam
versus Fourth-Generation Cephalosporins for Empirical Treatment of
Febrile Neutropenia in Patients with Hematological Malignancies |
In the present study, the overall
efficacy rate was 57.0% in the Fourth-Generation Cephalosporins group
and 59.2% in the Piperacillin/Tazobactam group. No adverse drug reaction
requiring discontinuation or switching of the study treatments was noted in any of the patients. |

Out
of 528 subjects (265 received Piperacillin-Tazobactam and 263 received
Cefepime), success rates were 57.7% and 48.3%, respectively (P = .04) at the 72-h time point, 39.6% and 31.6% (P = .06) at end of treatment, and 26.8% and 20.5% (P = .11) at the test-of-cure visit. The analyses demonstrated noninferiority for Piperacillin-Tazobactam at all time points (P ?.0001). This trial, taken together with other large clinical trials,
firmly establishes the safety and efficacy of Piperacillin-Tazobactam
monotherapy for the empirical treatment of the febrile neutropenic patients with cancer |

Piperacillin/Tazobactam in Moderate to Severe Bacterial Infections |
Piperacillin/Tazobactam
has shown clinical and economic advantages over standard antibacterial
regimens in the treatment febrile episodes in patients with neutropenia.
Present data regarding clinical efficacy, bacterial resistance and
costs would support the use of Piperacillin/Tazobactam as an empirical
first-line option in moderate to severe bacterial infections. |
Advantages of Piperacillin-Tazobactam:
Cephalosporins resistant Gram-negative bacteremia in febrile neutropenic patients with
hematological malignancies has increased significantly, particularly in
the ICU, in the past decade. The main mechanism accountable for is the
emergence of extended-spectrum beta-lactamases (ESBLs). These
plasmid-mediated beta-lactamases confer resistance to majority of the
broad-spectrum beta-lactam antibiotics like third- and fourth-generation cephalosporins.
Piperacillin/Tazobactam is currently considered as the drug of choice
for these pathogens. Prevention and control measures are important
because of the multiresistant nature of these pathogens. Such traditional infection
control measures as contact precautions are recommended. This type of
antimicrobial resistance appears to be particularly influenced by
antibiotic use. Antibiotic control measures may also be a very important
intervention in controlling the spread of ESBLs.6
Cost analysis of
Piperacillin/Tazobactam has been variable, in part, because of
differences in specific costs included. The US cost analysis shows that
Piperacillin/Tazobactam has lower total medical costs than other antibiotics. Intravenous antibiotics: acquisition costs per febrile neutropenia episode are summarized in the table 2.7

Conclusion:
Piperacillin/Tazobactam has shown clinical as well as the economic
advantages over other antibacterial regimens in the treatment of febrile
episodes in patients with neutropenia. It is likely to reduce overall
treatment costs of moderate to severe febrile neutropenia by increasing
initial treatment success thereby reducing the length of hospital stay
and the use of additional antibacterials. Present data regarding
clinical efficacy, safety and costs would support the use of
Piperacillin/Tazobactam as an empirical first-line option in moderate to
