Study the Impact of Statins in Septic Shock

Objectives:

• Study impact of statins on levels of biomarkers (IL-6 and TNF-α) of sepsis.
• Study survival benefit of statins in septic shock.

Introduction:

Sepsis is the leading cause of mortality in non-coronary ICUs. Mortality associated with sepsis is still considerably high. Rising economic burden of managing sepsis is a major concern. Statin is an anti-hyperlipidemic drug with pleiotropic effects. It has properties like anti-inflammatory/oxidative, immunomodulatory effects, enhances endothelial function, reduction in blood thrombogenicity, and increased nitric oxide (NO) bioavailability. Available evidence suggests that statins may play a positive role in reduction of mortality in sepsis. However, the multidimensional heterogeneous character of the available studies does not allow drawing firm conclusions about its usefulness in sepsis and septic shock. This randomized, double blinded, placebo controlled trial is an attempt to study the impact of statins on mortality and biomarker levels in septic shock.

Details of material and methods:

Patients >= age 18 yrs meeting the American European consensus conference definition of septic shock will be enrolled into the study. After the written informed consent from the primary decision maker the patients will be randomized into either the drug or placebo group. Each group will either receive Atorvastatin 40mg or a matched placebo for 7 days. IL-6 and TNF alpha levels will be estimated on D1, D4 and D7 of the trial week. Relevant clinical and laboratory (clinical biochemistry, hematological, coagulation parameters, LFT and renal function tests) will be recorded simultaneously. Severity scores, event free days (vasopressor, ventilation, dialysis, transfusion, parenteral nutrition), and mortality after 28 days of inclusion in study will be recorded.

Ethical Issues:

Written informed consent will be taken from either the patient (if possible) or from the primary decision maker related to the patient.

Study population:

A total of 80 patients of septic shock admitted in ICU will be enrolled into this study. Patients either admitted with septic shock or who develop septic shock during their stay in ICU will be eligible for inclusion into the study. The statin and placebo group will have 40 patients each.
