Pseudolithiasis due to ceftriaxone treatment for meningitis in children: report of 8 cases.
Cholelithiasis rarely occurs in childhood. Ceftriaxone is a widely used antimicrobial agent in pediatrics due to the broad spectrum. Reversible biliary sludge and/or lithiasis, named as pseudolithiasis, have been reported in patients treated with ceftriaxone. We observed ceftriaxone-associated pseudolithiasis in 8 patients with meningitis. The aim of this study was to report the clinical characteristics of these patients and to evaluate the related factors for the development of ceftriaxone-associated pseudolithiasis in children. The study group consisted of 7 boys and 1 girl. All patients received ceftriaxone 100 mg/kg/day for meningitis. The ultrasonographic evaluation was performed on 5th-10th days after the initiation of the therapy. Biliary sludge was detected in one patient, and gallstone was detected in three patients, while biliary sludge with gallstone was detected in four patients. Six of the cases were diagnosed during summer time. Thus, high temperature may cause loss of fluid, leading to easier formation of sludge. Ceftriaxone treatment was discontinued after sonographic demonstration of pseudolithiasis. Gallbladder sonograms were found to be normal in all patients at the follow-up sonographic examinations performed after 30 days of the diagnosis without specific treatment. Clinicians should screen all pediatric patients living in areas with high temperature and receiving ceftriaxone treatment (over 100 mg/kg) by ultrasonography for biliary sludge or gallstone formation even if they are asymptomatic.
