Adjuvant Use of Neostigmine in Sepsis and Septic Shock.

Phase 2

Completed

• Conditions: Sepsis, Septic Shock
• Interventions: Drug: Standard therapy; Drug: Neostigmine

• Registration Number: NCT04130230
• Lead Sponsor: Mansoura University

Brief Summary

The inflammatory response represents an important, central component of sepsis. Therefore, it is believed that blunting inflammation will decrease mortality. In vivo test series with mice that had undergone cecal ligation and puncture (recognized sepsis model), physostigmine salicylate significantly inhibited the release of various cytokines (tumor necrosis factor α, interleukin1β, and interleukin 6). These results were similar to those obtained by vagus nerve stimulation.

In animal sepsis model using physostigmine not only decreased inflammation but also, diminished the decrease in blood pressure following infection.

Animals treated with the peripheral choline esterase inhibitor neostigmine showed no difference compared with physostigmine-treated animals. Therefore, this study aims to investigate the efficacy of choline esterase inhibitors as adjuvant therapy in patients with sepsis or septic shock. Outcome measures include: percentage reduction in procalcitonin blood level, percentage of patients achieving significant reduction in procalcitonin levels, Mean Sequential Organ Failure Assessment score, percentage decrease in lactate dehydrogenase blood level, length of stay in hospital intensive care unit, and in hospital mortality.

Arm && Interventions

Group	Intervention	Description
Standard group	Standard therapy	This arm will receive the standard therapy for sepsis and septic shock only and followed for five days.
Neostigmine group	Neostigmine	This arm will receive -in addition to standard therapy for sepsis and septic shock-Neostigmine methylsulfate ampoule diluted in normal saline, and administered as continuous infusion for five days. The rate of infusion is 0.2 mg/hr.

Primary Outcome Measures

Name	Time	Method
Sequential organ failure assessment (SOFA score)	Change from baseline SOFA score at five days	Increase in SOFA score is associated with worse outcome.
