About this trial
This study will evaluate the safety and effectiveness of melatonin for the prevention of antibiotic associated acute kidney injury in hospitalized patients.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Aged 18 to 75 years
Currently prescribed vancomycin with the presumption that therapy will be continued for at least 3 days based on a review of subject status. Because of the critical nature of starting empiric broad-spectrum antibiotics, we will allow one dose of the antibiotic combination before consent and enrollment. This strategy is necessary for the ethical conduct of the study.
Disqualifiers
Estimated creatinine clearance < 30 mL/min
Liver impairment (liver enzymes > 3 times upper limit)
Any history of allergy or contraindication to melatonin
Pregnancy or breastfeeding

Trial outcomes
Primary outcomes
Acute kidney injury
Acute kidney injury will be defined as an increase in sCr from baseline of \>/= 0.3 mg/dL or a \>/= 50% increase from baseline.
Other outcomes
Melatonin plasma trough concentration
Evaluate the steady state plasma trough concentration of melatonin
Piperacillin/tazobactam plasma trough concentration
Evaluate the steady state plasma trough concentration of piperacillin/tazobactam
Vancomycin plasma Area Under the Curve (AUC)
Evaluate the steady state plasma AUC of vancomycin
Association between Kidney Injury Molecule-1 (KIM-1) and serum creatinine
Measure KIM-1 in plasma and urine and evaluate discordance between serum creatinine.
