Ceftolozane-Tazobactam cohortCeftolozane/tazobactamPatients older than 18 years old that are hospitalised in the Virgen Macarena University Hospital that are being treated with Ceftolozane-Tazobactam in empiric or targeted treatment.
Primary Outcome Measures
NameTimeMethod
Determine the Ceftolozane-Tazobactam seric concentrations and analyse the clinic impact that could have the dose regimens used until now.Up to 12 months after the antibiotic administration

Determination of the Ceftolozane-Tazobactam seric concentration by collecting 4 blood samples and measuring its antibiotic levels and if it´s achieved an adequate therapeutic efficacy assessed by the patient´s clinical and microbiological recovery.

The dose regimens used until now are 1+0,5 g every 8 hours in case of intra-abdominal infection or complicated urinary infection and 2 +1 g every 8 hours in case of pneumonia or septic shock of any focus.

Secondary Outcome Measures
NameTimeMethod
Analyse if with both dose regimens are achieved the PK/PD parameters associated with the maximum therapeutic efficacy in patients with renal hyper clearance.Up to 12 months after the antibiotic administration

Determine if with both dose regimens are achieve the pharmacodynamic and pharmacokinetic parameters associated with the maximum therapeutic efficacy in patients that have creatinine clearance above 130 ml/min.

Determine if in patients with Gram-negative bacillary bacteremia are achieved concentrations that are 100 % of the time 4 times above the minimum inhibitory concentration (MIC).Up to 12 months after the antibiotic administration

Determination of if in patients with Gram-negative bacillary bacteremia (patients with their bloodstream invaded by Gram-negative bacillary which is diagnosed by blood culture) are achieved concentrations that are 100 % of the time 4 times above the MIC by strips of isolated pathogen gradient .

Determine by a Monte Carlo simulation model the dose regimen that should be used.Up to 12 months after the antibiotic administration

Determination by a Monte Carlo simulation model of the dose regimen that should be used based on the pharmacokinetic parameters and according to the defined efficacy pharmacodynamic parameters.

Describe the Ceftolozane-Tazobactam treatment´s clinical result as well as existence of adverse effects.Up to 12 months after the antibiotic administration

Description of the Ceftolozane-Tazobactam clinical results as well as the rate and seriousness of adverse effects.

Describe the frequency of resistance´s development during the Ceftolozane-Tazobactam treatment and, if it´s possible to evaluate if there´s a correlation with the seric levels.Up to 12 months after the antibiotic administration

Description of the rate of resistance´s development during the Ceftolozane-Tazobactam and if there´s a correlation with the Ceftolozane-Tazobactam seric levels.

Determine the Ceftolozane-Tazobactam seric concentrations and analyse if with both dose regimens are achieved the PK/PD parameters associated with the maximum therapeutic efficacy in patients with morbid obesity.Up to 12 months after the antibiotic administration

Determination of the Ceftolozane-Tazobactam seric concentration by collecting 4 blood samples and measuring its antibiotic levels and if with both dose regimens are achieve the pharmacodynamic and pharmacokinetic parameters associated with the maximum therapeutic efficacy in patients that have BMI (body mass index) above 40

Determine the Ceftolozane-Tazobactam seric concentrations and analyse if with both dose regimens are achieved the PK/PD parameters associated with the maximum therapeutic efficacy in patients with continuous renal replacement technique.Up to 12 months after the antibiotic administration

Determination of the Ceftolozane-Tazobactam seric concentration by collecting 4 blood samples and measuring its antibiotic levels and if with both dose regimens are achieve the pharmacodynamic and pharmacokinetic parameters associated with the maximum therapeutic efficacy in patients that have their blood purified extracorporeally, replacing the renal function continuously 24 hours of the day.
