Study on Aminophylline and Sepsis

A recent study by Ruifang Zhang and peers found aminophylline to reduce the risk of death and prolong the survival time of patients with sepsis. The findings were published in Chinese Medical Journal.

Sepsis is a serious and potentially life-threatening condition that results from a severe infection. It can cause a range of symptoms and complications, including organ failure, septic shock, and death. Treatment for sepsis usually involves antibiotics and supportive care to help the body fight the infection and restore normal functioning. Recently, researchers have explored the use of aminophylline, a drug typically used for treating asthma and other respiratory conditions, as an adjunctive therapy for sepsis.

Clinical Trial

A clinical randomized controlled trial was conducted to evaluate the safety and efficacy of aminophylline in the treatment of sepsis. The trial involved 100 patients diagnosed with sepsis who were admitted to an ICU within 48 hours of diagnosis. The patients were randomly assigned in a 1:1 ratio to receive either standard therapy or standard therapy plus aminophylline. The primary clinical outcome was all-cause mortality at 28 days.

Findings

• Patients receiving aminophylline as an adjunctive therapy had a lower risk of death compared to those receiving standard therapy alone.
• At 28 days, 14.0% of patients in the aminophylline group had died, compared to 32.0% in the control group.
• Cox regression analysis showed that the aminophylline group had a lower hazard of death (hazard ratio = 0.312, 95% confidence interval: 0.129–0.753).
• Patients in the aminophylline group had a longer survival time compared to the control group.
• The study also showed that aminophylline had a time-dependent effect on vasopressor dose, oxygenation index, and sequential organ failure assessment score, with treatment.
• There were no significant differences in total hospitalization days, ICU hospitalization days, or rates of serious adverse events between the two groups.
• Importantly, no adverse events were observed during the trial.
