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.
