He is a graduate of the University of Minnesota, where he completed his residency and an endowed fellowship in infectious diseases and pharmacokinetics.

He maintains a busy clinical consultation practice with bedside teaching of medical residents, represents the Department of Pediatrics on the Pharmacy and Therapeutics Committee and on the Antimicrobial and Medication Safety Subcommittees at LAC+USC Medical Center, and has served on medical expert panels for the Department of Health Services. He has published and presented numerous scientific papers and book chapters on pharmacokinetics, antimicrobials and drug resistance, antiepileptic and cardiovascular drugs. He is a content editor on anivirals and antifungals for the forthcoming issue of the American Academy of Pediatrics’ Redbook.

Areas of research emphasis include predictive performance of pharmacokinetic models for dosing in children and novel pharmacotherapeutic applications of drugs such as amphotericin and erythromycin in neonates. This diversity in areas of expertise is reflected in his programmatic efforts and teaching, from bedside to classroom, at USC. He has trained numerous pediatric pharmacotherapy residents and fellows who have gone on to distinguished careers.

Steinberg is a noted national speaker for many physician and pharmacist audiences, and has given hundreds of lectures and continuing education programs in 43 states in the U.S. His expertise in legal medicine is nationally regarded and sought after in court and arbitration disputes involving pharmacologic and toxicologic issues.

      Acyclovir dosing and acute kidney injury: Deviations and direction

      The Journal of Pediatrics
      Irving Steinberg

      2015 When admitted to the hospital almost all patients will receive a standard battery of blood tests, which includes a Complete Blood Count (CBC). Often a primary care office will order such work for their patients simply to have a baseline, and many specialists will do so as a means to monitor drug reactions and overall health.

      Renal tolerance with the use of intralipid-amphotericin B in low-birth-weight neonates

      American Journal of Perinatology
      Irving Steinberg

      1997 Amphotericin B is still the first-line therapy for neonatal fungal infections. With several comparative trials of intralipid-based amphotericin B (IL-AmB) demonstrating its clinical effectiveness and reduced renal toxicity in adults, we examined the renal tolerance and infection outcome in low-birth-weight infants in our 48-bed NICU treated with IL-AmB. Over 2 years, 52 patients (58 courses) received > or = 10 days of IL-AmB. Nineteen charts (23 episodes) were randomly accessed and reviewed. Mean birthweight = 747 grams, gestational age = 25.6 weeks, total IL-AmB dosage = 19.8 +/- 3.3 mg/kg (n = 23); 20 of these episodes were fungal culture positive (9 fungemias). Only one patient (who died during therapy) had a rise in creatinine of > 0.3 mg/dL. Overall, serum creatinine decreased significantly after Day 10 of IL-AmB therapy, from 0.93 +/- 0.42 mg/dL at baseline, to 0.54 +/- 0.24 after 19 days of therapy (p < 0.0001). Serial urine output, serum potassium and potassium supplementation data showed no significant differences from baseline. No interruption of therapy nor infusion reactions occurred. Only one death occurred attributable to fungal infection. Intralipid-amphotericin B may provide an effective alternative in the antifungal therapy of low birthweight neonates, without nephrotoxicity. Further prospective, comparative trials are warranted.
