Early Antibiotic in Sepsis

Details and patient eligibility

About

The aim of this study is to assess the efficacy of early targeted antibiotic therapy in patients with sepsis and septic shock using the new biomarker Sirtuin 1 and PCR for bacterial resistance detection.

The primary outcome is change in SOFA score (ΔSOFA) which will be calculated by subtracting the final SOFA score and sirtuin 1 level at 5 days from the corresponding initial value at enrollment.

Secondary outcomes included mortality rates, ventilator free days and length of icu stay.

Full description

• A prospective, single-center, open labeled, randomized interventional study

• Patients will be recruited from a private hospital in Alexandria

• Approval will be obtained from Research Ethics Committee of Faculty of Pharmacy, Damanhour University

• Fourty eight critically ill patients, with sepsis and septic shock according to the 2016 third international consensus definitions, will be included

• Patients with risk for Carbapenemase producing organisms:

  • Use of broad spectrum cephalosporins and/or carbapenems within the past three months
  • Polytrauma
  • Diabetes
  • Malignancy
  • Organ transplantation
  • Mechanical ventilation
  • Indwelling urinary or venous catheters
  • Overall poor functional status or severe illness
  • Residence in a long-term care facility(18-28).

• The baseline characteristics of the patients will be collected at the time of enrollment. The collected data included age, sex, ratio of septic shock to sepsis, ratio of ventilated to non-ventilated patients, source of infection, vital signs, laboratory data, arterial blood gas (ABG), APACHE II score, Glasgow Coma Scale score, and SOFA scores. The level of Procalcitonin (PCT) and Sirtuin-1 will also be measured at this time(29).

• Patients will be randomly allocated to antibiotic regimen guided by conventional culture technique (n=24) or targeted antibiotics therapy guided by resistance genotyping (n=24) (29, 30).

• Levels of Sirtuin1 will be detected using ELISA kits as prescribed by manufacturer.

• Traditional diagnostic microbiology techniques relying on the growth of organisms on appropriate culture media (Control group).

• Qualitative Multiplex pcr test will be used for rapid detection of carbapenemases genes (Intervention group)

• Statistical tests appropriate to the study will be conducted to evaluate significance of results

• Results, conclusion, discussion and recommendations will be given.
