OBJECTIVE: To report a case of reversible vancomycin-associated neutropenia occurring during long-term therapy with vancomycin using weight and age-adjusted dosing. CASE SUMMARY: A 2-year-old boy was started on vancomycin therapy for presumed endocarditis resulting from his ventriculoseptal defect. After 18 days of treatment, neutropenia with an absolute neutrophil count (ANC) of 990 × 106 cells/L was noted. The neutropenia progressed over the next 3 days and reached a nadir concentration of 459 × 106 cells/L. Vancomycin therapy was discontinued after 17 days (antibiotic day 20). A rise in the ANC occurred within 2 days of discontinuation. An improved ANC of 1672 × 106 cells/L occurred within 5 days. Vancomycin serum concentrations remained within an acceptable range: a peak of 30 μg/mL and a trough of 9 μg/mL. DISCUSSION: Case reports in the literature of vancomycin-associated neutropenia in adults were briefly reviewed and compared. The onset and resolution and mechanism of vancomycin-induced neutropenia were studied. The potential relationship between vancomycin, weight-, and age-adjusted dosing and the occurrence of neutropenia in our pediatric patient was postulated. CONCLUSIONS: Vancomycin is identified as a possible cause of drug-induced neutropenia. More data are needed that clearly indicate vancomycin as the offending agent in children. The vancomycin-induced neutropenia is believed to be immunologically based and independent of drug concentrations.

This study represents the first in a series of investigations carried out to elucidate the mechanism(s) of early hepatocellular damage induced by drugs and other related compounds. During screening tests of CNS-active compounds in rats, it has been found that daily oral administration of one of these compounds at a dose level of 40 mg. per kg. of body weight induced diffuse massive hepatic necrosis within 7 weeks in Charles River Sprague Dawley rats of both sexes. Partial hepatectomy enhanced the development of this peculiar type of necrosis (3 weeks instead of 7) while treatment with phenobarbital prior to the administration of the drug delayed the appearance of necrosis but did not reduce its severity.Electron microscopic studies revealed that early development of this liver injury (2 days after the administration of the drug) appeared in the form of small dark osmiophilic vesicles located around the bile canaliculi of all hepatocytes (Fig. 1). These structures differed from the regular microbodies or the pericanalicular multivesicular bodies. They first appeared regularly rounded with electron dense matrix bound with a single membrane. After one week on the drug, these vesicles appeared vacuolated and resembled autophagosomes which soon developed whorls of concentric lamellae or cisterns characteristic of lysosomes (Fig. 2). These lysosomes were found, later on, scattered all over the hepatocytes.
