Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Aminophylline and theophylline, methylxanthine nonselective adenosine receptor antagonists, have been effective in the management of AKI in certain clinical scenarios including heart failure, calcineurin inhibitor toxicity, and perinatal asphyxia. In the kidney, adenosine constricts the afferent arteriole and decreases glomerular blood flow; adenosine receptor blockade mitigates this vasoconstriction. Aminophylline also inhibits phosphodiesterase at higher concentrations, which leads to increased urine output.
Eligible subjects included all patients more than 18 years old with acute kidney injury in ICU. To ensure the safest oversight for the duration of the study drug infusion, the investigators only approached patients for consent if participants' ICU stay would likely be at least 72 hours . Patients were recruited in the preoperative clinic or in the inpatient ward/ICU; the nature of the consent process for this interventional drug trial necessitated that all procedures were elective or scheduled. Because aminophylline has been associated with tachycardia and seizures at high serum levels, and its metabolism may be affected by liver or thyroid dysfunction and sepsis, the investigators selected the following exclusion criteria: history of tachyarrhythmias, seizures, coagulopathy (international normalized ratio \> 1.5 while not taking warfarin),or hypothyroidism. Study investigators or research nurses recruited participants; written, informed consent was signed by each patient or guardian.
The treatment group received aminophylline 5 mg/kg IV load over 30 minutes, followed by 0.5 mg/kg IV every hour, for 72 hours .The control group received placebo bolus followed by IV infusions of normal saline (0.9%) every hour (matched by volume and appearance to the treatment group), for 72 hours.
