Ceftriaxone-associated biliary sludge and pseudocholelithiasis during childhood: a prospective study

Ceftriaxone Administration Associated with Lithiasis in Children: Guilty or Not? A Systematic Review

Lithiasis is a known side effect of ceftriaxone administration in children. Sex, age, weight, dosage, and duration of intake have been reported as risk factors for the formation of calcification or stones in the bile and urine excretory systems of children who received ceftriaxone. The purpose of this systematic review is to investigate the reported effects of ceftriaxone administration in pediatric patients who were admitted to a hospital due to infection, the likelihood of gallstones, nephroliths, or precipitations in both the biliary and urinary systems, as well as investigate the relationship with their mother's history during pregnancy. Original studies and literature reviews from the PubMed database were included in the study. No time limit related to research or publication was set for the articles. The results were evaluated, aiming to understand the outcomes and identify any predisposing factors relevant to this side effect. Of the 181 found articles, 33 were appropriate for inclusion in the systematic review. The administered dose of ceftriaxone presented variability. Symptoms, such as abdominal pain and vomiting, were associated with ceftriaxone-related lithiasis in many cases. It was noted that most of the results were the outcomes of retrospective observation and not of prospective randomized research. Definitively, more randomized control studies with long-term outcomes are needed to identify the exact association between ceftriaxone and lithiasis in children.

Rapid onset of ceftriaxone-induced cholelithiasis in an adult patient

Ceftriaxone is a third-generation cephalosporin with broad-spectrum antibacterial activity. Here, we report a case of ceftriaxone-induced cholelithiasis in an adult patient after a short period of administering ceftriaxone. A 57-year-old female was admitted to our hospital for meningitis and treated empirically with ceftriaxone 2 g every 12 hours. Other medications given included vancomycin, ampicillin and acyclovir. Based on culture results and a sensitivity report, ceftriaxone was continued while other medications were discontinued on day three after admission. Her liver function test (LFT) demonstrated an elevation in hepatic transaminases, and alanine and aspartate transaminases peaked on the fifth day (339 and 153 IU/L, respectively). Computed tomography (CT) and ultrasound (US) confirmed the presence of uncomplicated cholelithiasis. Ceftriaxone was discontinued and switched to cefotaxime 2 g every four hours. Hepatic transaminases started declining after ceftriaxone discontinuation and dropped to normal levels on day nine. After the administration of cefotaxime on the 25^th day, repeated US imaging revealed the persistence of biliary sludge. The patient was discharged in a good and stable clinical condition with follow-up planned at the outpatient clinic. When the concentration of ceftriaxone in the gallbladder exceeds the solubility of its calcium salt, precipitation occurs, forming a biliary sludge. Using the Naranjo Probability scale, the score was found to be 4, indicating a possible relationship between ceftriaxone and cholelithiasis. Multiple case reports of ceftriaxone-induced cholelithiasis have been documented previously, most of which focused on children or on the prolonged use of ceftriaxone. However, our case report highlights the development of cholelithiasis in adults after administering ceftriaxone for a short time.

The Intestinal Flora at Kasai Procedure in Children with Biliary Atresia Appears Not to Affect Postoperative Cholangitis

INTRODUCTION

 Evidence supports long-term oral antibiotic prophylaxis to prevent cholangitis after Kasai procedure. Data regarding perioperative intravenous prophylaxis are lacking. Ascending pathogens from the intestine are made responsible for recurrent cholangitis. Therefore, we analyzed the flora in the upper jejunum during the Kasai procedure and their potential impact on postoperative cholangitis.

MATERIALS AND METHODS

 In 26 patients, swabs were taken at the bowel prepared for the Roux-en-Y-loop. Our postoperative protocol includes intravenous third-generation cephalosporins for 2 weeks and rectal steroids starting at day 4. Cholangitis was defined as the postoperative reappearance of acholic stools or increase of serum bilirubin in combination with fevers or increase of inflammatory parameters. In this scenario, Tazocin was administered for another 2 weeks.

RESULTS

 Swabs remained sterile in nine patients (34.6%). In 17 patients (65.4%), gram-positive and gram-negative pathogens were identified; all belonging to physiological intestinal flora. A total of 96.2% pathogens were covered by the antibiotic prophylaxis. The cholangitis incidence was 55.6% in the sterile cohort, and 23.5% in the gram-positive and gram-negative cohort (p = 0.06). In the cholangitis cohort, no significant differences were detected for the age at Kasai and the pre- and postoperative total bilirubin.

CONCLUSION

 We found that our antibiotic regiment covered bacteria in the upper gastrointestinal (GI) tract in the majority of our patients at the time of Kasai. Nonetheless, a significant proportion of patients developed signs of cholangitis. There was no higher rate of cholangitis in patients with resistant bacteria. Thus, our data do not support the hypothesis of extended postoperative intravenous antibiotics to prevent ascending cholangitis.

Ceftriaxone-associated biliary pseudolithiasis in children: do we know enough?

Ceftriaxone is an antibiotic agent frequently used in paediatric hospital practice for the treatment of severe bacterial infections. The use of this agent can result in cholelithiasis and/or biliary sludge, more commonly in children than in adults. This systematic review was aimed at analysing available literature concerning ceftriaxone-associated biliary pseudolithiasis in paediatric patients, with a special emphasis on the clinical aspects. A literature analysis was performed using Medline and Embase electronic databases (articles published in English up to December 2019), with the search terms and combinations as follows:'ceftriaxone', 'cholelithiasis', 'biliary sludge' 'gallstones' 'neonates' 'children' 'clinical aspects' 'management'. Several case reports, case series and prospective/retrospective studies have documented a relationship between ceftriaxone treatment and biliary pseudolithiasis in the paediatric population, even though literature data regarding neonates and infants are scarce. Ceftriaxone-associated biliary pseudolithiasis is dose-dependent and usually asymptomatic but, sometimes, it may present with abdominal pain, nausea and emesis. Abdominal ultrasonography should be performed when this complication is suspected. Generally, ceftriaxone-associated cholelithiasis resolves over a variable period of time (days to months) after cessation of therapy. Therefore, a conservative approach to this condition is advocated, but a prolonged follow-up may be necessary. A personalized assessment of factors predisposing to ceftriaxone-associated biliary pseudolithiasis before prescribing the drug can allow to minimize the risk of developing it, with significant advantages in terms of human and economic costs.

Asymptomatic ceftriaxone-associated pseudolithiasis

An 88-year-old woman with a history of meningioma and dementia was admitted with high fever, loss of appetite, and nausea in July. Urinary tract infection was suspected. Computed tomography (CT) showed no significant findings. Urinary findings improved with administration of ceftriaxone. However, high fever appeared on hospital day 28, and CT identified a gallbladder stone without any abdominal symptoms. We considered the possibility of ceftriaxone-associated pseudolithiasis and changed pharmacotherapy to cefmetazole. CT on day 34 showed a reduction in the size of the gallbladder stone. Ceftriaxone-associated pseudolithiasis might arise in the absence of abdominal symptoms, and clinicians should take the patient background and season into account when using this agent.

Risk factors of ceftriaxone-associated biliary pseudolithiasis in adults: influence of renal dysfunction

BACKGROUND

Ceftriaxone (CTRX) is a known cause of biliary pseudolithiasis (BPL) mainly in children. Biliary elimination of CTRX increases in patients with renal dysfunction. However, the influence of renal dysfunction on the incidence of CTRX-associated BPL has not been well investigated. The aim of this study was to investigate the cumulative incidence of CTRX-associated BPL in adults and to assess if renal dysfunction is a risk factor.

METHODS

We retrospectively analyzed the medical records of 478 patients treated with CTRX to assess the incidence and risk factors of CTRX-associated BPL. We examined age, sex, body weight, dosage, and duration of CTRX therapy, and the concentrations of serum creatinine, estimated glomerular filtration rate (eGFR), albumin, and serum calcium in all the patients. The cumulative incidence of BPL was calculated using a competing risk model. The multivariate analysis of each variable for the development of BPL was assessed by a Cox proportional hazards model.

RESULTS

A total of 362 patients (75.7%) had renal dysfunction (eGFR: < 60 mL/min). The cumulative incidence of BPL in patients with renal dysfunction was significantly higher than that in patients with normal kidney function (4.1 vs. 0.6%, p = 0.017). Renal dysfunction (Hazard ratio (HR) 8.14, 95% CI 1.05-63.0, p = 0.045) and female sex (HR 5.35, 95% CI 1.17-24.5, p = 0.031) were independent risk factors of CTRX-associated BPL, which was confirmed using multivariate analysis (renal dysfunction: HR 7.93, 95% CI 1.04-60.5, p = 0.046) (female sex HR 4.65, 95% CI 1.03-21.1, p = 0.046).

CONCLUSIONS

Renal dysfunction is an independent risk factor of CTRX-associated BPL in adults.

Drug Hepatotoxicity: Newer Agents

Idiosyncratic hepatotoxicity is one of the most common reasons for an approved drug being restricted. This article focuses on hepatotoxicity of selected and recently introduced agents, such as, tyrosine kinase inhibitors, monoclonal antibodies, novel oral anticoagulants, newer antiplatelets, antibiotics, anti-diabetics, anti-epileptics, anti-depressants, anti-psychotics and anti-retrovirals. Overall, the incidence of clinically relevant hepatotoxicity from newer agents seems to be lower than that of the older agents. Nevertheless, cases of severe hepatotoxicity have been reported due to some of these newer agents, including, trastuzumab, ipilimumab, infliximab, imatinib, bosutinib, dasatinib, gefitinib, erlotinib, sunitinib, ponatinib, lapatinib, vemurafenib, dabigatran, rivaroxaban, felbamate, lamotrigine, levetiracetam, venlafaxine, duloxetine, darunavir, and maraviroc.

Gallstones in childhood: etiology, clinical features, and prognosis

AIM

The aim of this study was to determine demographic and clinical features in children diagnosed with gallstones, risk factors for gallstone formation, the effectiveness of ursodeoxycholic acid therapy, and the course of the disease.

MATERIALS AND METHODS

Patients aged 0-18 years were followed up for at least 6 months after the diagnosis of gallstones with ultrasonography and were evaluated retrospectively. Patients were evaluated with respect to age, sex, presenting symptoms, BMI, facilitating factors, accompanying diseases, family history of gallstones, history of ceftriaxone use, laboratory tests, ultrasonography findings and follow-up, and therapeutic approaches and results.

RESULTS

The study was completed with 70 patients. Thirty-nine (55.7%) patients were females. The mean age of the patients was 9.3±5.29 (0.3-18) years. The mean age among females was statistically significantly higher than that among males (P=0.007).No risk factor for stone formation was encountered in 50% of cases, whereas a family history of gallstones was present in 17.1%. Use of ceftriaxone was present in 8.6% of cases, total parenteral nutrition in 10%, obesity in 5.7%, hereditary spherocytosis in 4.3%, and Down's syndrome in 4.3%. The probability of dissolution of stones was 3.6 times higher in patients with stone sizes up to 5 mm [odds ratio (OR): 3.65, P=0.020], 3.9 times higher in those aged younger than 2 years (OR: 3.92, P=0.021), and 13.9 times higher in those with a single stone (OR: 13.97, P=0.003).

CONCLUSION

Our findings show that unknown causes are still prevalent in stone formation and that ursodeoxycholic acid exerts no effect on stone dissolution; however, diagnosis at younger than 2 years of age, a single stone, and small size of stone are factors affecting dissolution.

Risk factors, complications and outcome of cholelithiasis in children: A retrospective, single-centre review

AIM

The aim of this study was to evaluate the clinical presentation, risk factors, complications, treatment and outcomes of cholelithiasis in children.

METHODS

Children with cholelithiasis were reviewed for demographic information, predisposing factors, presenting symptoms, laboratory findings, complications, treatment and outcome, retrospectively.

RESULTS

A total of 254 children with cholelithiasis (mean age: 8.9 ± 5.2 years) were recruited to the study. Girls (52.8%) were significantly older than boys (P < 0.001). Symptomatic patients (59%) were significantly older than asymptomatic patients (P = 0.002). Abdominal pain was the most frequent symptom. No risk factors were identified in 56.6% of the patients. Ceftriaxone (20%) was the most commonly associated risk factor. At presentation, at least one of the following complications was seen in 14.1% of patients: cholecystitis (10.9%), obstructive jaundice (2.7%), pancreatitis (1.96%) and cholangitis (1.2%). There was no relationship between gallstone size and symptoms, aetiological factors and complications. The cholelithiasis dissolution rate was higher in younger children (P = 0.032), in those with biliary sludge (P < 0.0001) and ceftriaxone-related cholelithiasis (P < 0.001). Haemolytic anaemia (P = 0.001) and older age (P = 0.002) were associated with stable stones. Ursodeoxycholic acid was administered to 94.4% of patients at presentation. Twenty-nine patients underwent cholecystectomy, and seven patients underwent endoscopic retrograde cholangiopancreotography. Patients who were symptomatic at presentation had significantly more frequent symptoms at follow-up (P < 0.001) CONCLUSIONS: Dissolution rate of cholelithiasis was higher in younger children, biliary sludge formation and ceftriaxone-related cholelithiasis but lower in older children and haemolytic anaemia-related cholelithiasis.

Preclinical Rodent Toxicity Studies for Long Term Use of Ceftriaxone

A 6-month rodent toxicology and pharmacokinetic (PK) study was performed to provide supportive safety data for long-term use of intravenous ceftriaxone in a clinical trial in patients with amyotrophic lateral sclerosis (ALS). Ceftriaxone was administered by subcutaneous injection at up to 2 g/kg/day to Sprague-Dawley Crl:CD (SD) rats. Ceftriaxone was found to be safe and well tolerated. Specifically, no significant differences in body weight and food consumption were observed between the treatment and control groups. With the exception of in red cell parameters decrease, there were no ceftriaxone-related changes in hematology, coagulation, clinical chemistry and urinalysis parameters. Injection site trauma and associated reversible anemia, likely due to chronic blood loss at the injection site, were all attributable to subcutaneous route of administration. Cecum dilatation and some skin changes were reversible after recovery period, while bile duct dilatation, observed only in a few animals, persisted. Changes in the non-glandular stomach do not have a human correlate. The no-observed-adverse-effect dose level (NOAEL) was 0.5 g/kg/day ceftriaxone in both sexes. Ceftriaxone showed rapid absorption with half-life values ranging between 1 and 1.5 hours. Additionally, there was no evidence of accumulation and a virtually complete elimination by 16 hours after the last dose. Overall there were no toxicologically meaningful drug-related animal findings associated with the long-term administration (6 months) of ceftriaxone. These results support safety of long-term use of ceftriaxone in human clinical trials.

Probable fatal drug interaction between intravenous fenretinide, ceftriaxone, and acetaminophen: a case report from a New Approaches to Neuroblastoma (NANT) Phase I study

Background

Patients with relapsed/refractory stage 4 high-risk neuroblastoma were enrolled on a phase I study (NANT2004-03) of intravenous fenretinide emulsion. Pharmacokinetic samples were collected during and after the infusion, and the levels were measured using an HPLC system. A likely case of a fatal drug interaction between fenretinide, ceftriaxone, and acetaminophen is described, including the pharmacokinetics of fenretinide, laboratory data, and post-mortem autopsy in a pediatric neuroblastoma patient treated on this study.

Case presentation

On Day 4 of a scheduled 5-day-infusion of intravenous fenretinide, the patient developed a fever, acetaminophen was started, ceftriaxone initiated for possible bacteremia, and fenretinide level doubled from 56 to 110 μM. Over the next three days, although blood cultures remained negative, the patient’s condition deteriorated rapidly. Acute liver failure was diagnosed on Day 7, and the patient expired on Day 20 of fulminant hepatic failure with associated renal, cardiac, and hemorrhagic/coagulation toxicities. Autopsy showed extensive hemorrhagic necrosis of the liver, marked bile duct proliferation, and abundant hemosiderin, consistent with cholestasis and drug toxicity.

Conclusions

After extensive review of patient data, the clinical course, and the literature, we conclude that observed hepatic toxicity was likely due to a drug interaction between fenretinide and concomitant ceftriaxone and acetaminophen. None of the other 16 patients treated on this study experienced significant hepatic toxicity. Although the prevalence of cholestasis with ceftriaxone usage is relatively high, the potential drug interaction with these concomitant medications has not been previously reported. Concomitant use of fenretinide, ceftriaxone, and acetaminophen should be avoided.

Ceftriaxone-induced pseudolithiasis in children treated for perforated appendicitis

PURPOSE

Ceftriaxone has been associated with development of pseudolithiasis. In our institution, it is used for treatment of perforated appendicitis in children. This study evaluated the occurrence of ceftriaxone-related pseudolithiasis in this population.

METHODS

After obtaining IRB approval, we performed a retrospective chart review over 51 months. We included patients undergoing laparoscopic appendectomy for perforated appendicitis. All patients were treated with ceftriaxone post-operatively. Patients without initial or post-treatment gallbladder imaging available for review were excluded.

RESULTS

There were 71 patients who met inclusion criteria with a mean (±SD) age of 10.8 ± 3.8 years. Of these, 14 % (n = 10) developed stones or sludge in the gallbladder. The mean duration of ceftriaxone therapy was 8.7 ± 3.8 days. The average time to post-antibiotic imaging was 11.5 ± 10.3 days from initiation of antibiotics. There was no significant difference in duration of ceftriaxone therapy in the children that developed pseudolithiasis or sludge (10.0 ± 4.9 days) compared to those that did not (8.5 ± 3.6, p = 0.26). One child (10 %) with pseudolithiasis went on to become symptomatic, requiring a laparoscopic cholecystectomy.

CONCLUSIONS

In our experience, ceftriaxone use for perforated appendicitis is associated with a significant incidence of biliary pseudolithiasis, and is unrelated to duration of ceftriaxone therapy.

The polymicrobial Actinomyces naeslundii and Pseudomonas aeruginosa sepsis in a patient with ulcerative colitis 2 months after colonoscopy

We describe a case of an abrupt onset of polymicrobial Actinomyces naeslundii/Pseudomonas aeruginosa sepsis in a patient with a previously silent abdominal actinomycosis, developed 2 months after colonoscopy when the diagnosis of a left-sided ulcerative colitis was established. Prolonged high-dose ceftriaxone therapy was clinically effective, albeit accompanied by the development of a reversible pseudocholelithiasis that persisted for 5 months.

Hepatotoxicity of antibiotics: a review and update for the clinician

Collectively, the various classes of antibiotics are a leading cause of drug-induced liver injury (DILI). However, acute antibiotic-associated DILI can be difficult to diagnose, as the course of therapy is usually brief, and other confounding factors are often present. In addition to the broad clinicopathologic spectrum of hepatotoxicity associated with the antimicrobials, the underlying infectious disease being treated may itself be associated with hepatic dysfunction and jaundice. This review provides summarized information on several classes of antimicrobial agents, highlighting new agents causing DILI and updating information on older agents.

Systemerkrankungen

Systemerkrankungen als Ursache einer Lebererkrankung sind häufig, ohne dass man genaue Zahlen angeben kann. Die verschiedenen Grunderkrankungen sind für sich betrachtet zwar selten, nur dadurch, dass viele Erkrankungen in Betracht gezogen werden müssen, ergibt sich eine relative Häufung. Durch Fortschritte auf dem Gebiet der molekularbiologischen Diagnostik insbesondere bei den Stoffwechselerkrankungen lassen sich heute bereits viele der in Frage kommenden Grunderkrankungen eindeutig nachweisen. Allerdings ist bei keiner der Erkrankungen ein hundertprozentiger molekularbiologischer Nachweis möglich. Damit ergibt sich eine sichere Diagnose nur bei einem positiven Nachweis. Bei fehlendem Nachweis einer bisher bekannten für die Erkrankung spezifischen Mutation bleibt die Zuordnung entweder enzymatischen Tests oder klinischer Diagnose vorbehalten. Insbesondere bei der Manifestation als akutes Leberversagen ist die für die Diagnosesicherung erforderliche Zeit damit oft nicht vorhanden.

Increased urinary calcium excretion caused by ceftriaxone: possible association with urolithiasis

The administration of ceftriaxone is known to be associated with biliary pseudolithiasis, although the development of urolithiasis has only rarely been reported. We treated a young male with bacterial meningitis complicated by urinary precipitates composed of ceftriaxone-calcium salt, which prompted us to study whether ceftriaxone administration predisposes children to the formation of urinary precipitates. The case-control study reported here included 83 children with bacterial pneumonia aged from 3 months to 8.9 years. The children were divided into one group of 43 children who received ceftriaxone (group A) and a second group of 40 children who received amoxicillin (group B). Paired samples of serum and urine before and after treatment were obtained from the patients in each group. There were no significant differences in demographic characteristics and blood biochemistry between the groups. However, the mean urinary calcium to creatinine ratio (uCa/Cr; mg/mg) was significantly higher in group A patients than in group B patients after treatment (0.19 vs. 0.09, respectively; p < 0.001), and analysis of the paired urine samples revealed that the uCa/Cr significantly increased after treatment only in group A patients(p < 0.001). There was a weak but non-significant relationship between the dose of ceftriaxone and the uCa/Cr in group A (p = 0.10, r = 0.24). Our results are the first to demonstrate that ceftriaxone has the potential to significantly increase urinary excretion of calcium, which may be linked to ceftriaxone-related urolithiasis or sludge. We therefore suggest that it is worthwhile monitoring the uCa/Cr levels in patients on ceftriaxone as they may be at greater risk for developing large stones and renal damage.

Urinary sludge caused by ceftriaxone in a young boy

It is known that ceftriaxone administration is associated with biliary pseudolithiasis, although the development of urolithiasis has been rarely reported. We encountered a young male with bacterial meningitis complicated by urinary precipitates composed of ceftriaxone-calcium salt which is confirmed by high-performance liquid chromatography. This patient suggested that ceftriaxone significantly increased urinary excretion of calcium, which may be linked to ceftriaxone-related urolithiasis or sludge. It is therefore worthwhile to monitor the levels of urinary calcium to creatinine ratio in patients on ceftriaxone, as they may be at greater risk for developing large stones and renal damage.

[Cholelithiasis in infants, children and adolescents]

The prevalence of cholelithiasis is estimated within 0.13% and 2% of children under 19 years of age. Pigment stones are the commonest type of gallstones in children, without recognizable predisposing factors in infants or secondary to a predisposing disease such as chronic hemolysis and ileal disease in children. In adolescents, idiopathic cholesterol gallstones accounts for the majority, such as in adults. Gallbladder stones are found in 80 to 90% of cases and common bile duct stones in 10 to 20% of cases. When common bile duct stones are found, a choledocal cyst with anomalous pancreatobiliary duct junction needs to be excluded. Magnetic resonance cholangiopancreatography should be performed in first line. Cholecystectomy is not indicated for silent gallstones, except in children with a predisposing disease such as chronic hemolysis. Treatment of common bile duct stones includes interventional radiologic, endoscopic or surgical procedures. Stone extraction may be performed at endoscopic retrograde cholangiopancreatography with or without sphincterotomy, combined with laparoscopic cholecystectomy. In children without a predisposing disease or no residual gallstones indicating a cholescystectomy, conservative management (percutaneous cholangiography with biliary drainage) may be proposed in specialised centers, especially for infants. A hepaticojejunostomy is indicated in cases of choledocal cyst with anomalous pancreatobiliary duct junctions.

Microlithiasis, endoscopic ultrasound, and children: not just little gallstones in little adults

PURPOSE

Biliary microlithiasis is an uncommon but recognized cause of upper abdominal pain, cholecystitis, cholangitis, and pancreatitis in adults. Gallstones smaller than 3 mm may not be seen on transabdominal ultrasound and may only be seen on endoscopic ultrasound. This condition is poorly described in children. The aim of this study is to review the results of laparoscopic cholecystectomy to treat biliary microlithiasis in a pediatric case series.

METHODS

We performed a retrospective case review of children with biliary microlithiasis who were treated with laparoscopic cholecystectomy.

RESULTS

Three children were diagnosed with biliary microlithiasis. Two patients had recurrent right upper quadrant pain and nausea. A third patient had midepigastric pain and idiopathic pancreatitis. All 3 had a normal gallbladder on transabdominal ultrasound. Additional imaging with hepatobiliary scan, computed tomography, and magnetic resonance cholangiopancreatography revealed no biliary source for symptoms. Endoscopic ultrasound was performed on all 3 children, demonstrating microlithiasis of the gallbladder. Each child had a laparoscopic cholecystectomy with intraoperative cholangiogram. No abnormalities were seen on intraoperative cholangiogram. All 3 children had alleviation of pain and improvement of symptoms in postoperative follow-up.

CONCLUSION

Children with biliary microlithiasis and associated clinical symptoms can be successfully treated with laparoscopic cholecystectomy. Endoscopic ultrasound should be considered in the evaluation of the child with clinical biliary symptoms and a negative transabdominal ultrasound result.

Sonographic Assessment of Ceftriaxone-Associated Biliary Pseudolithiasis in Chinese Children

In this randomized, single-blind, case-controlled, prospective study, the incidence and outcome of ceftriaxone-associated biliary pseudolithiasis in Chinese children was evaluated via ultrasonography. A total of 108 children diagnosed with hepatobiliary infection or pneumonia were randomized to receive ceftriaxone or ceftazidime. Serial gallbladder sonograms were obtained on days 1, 5 − 7 and 10 − 14 of therapy. Gallstones were detected in 43.10% of patients in the ceftriaxone-treated group and in 2.00% of the ceftazidime-treated group. The incidence of pseudolithiasis was significantly higher in the ceftriaxone-treated than the ceftazidime-treated group. Biliary precipitation abnormalities appeared after 2 − 7 days of treatment. After gallstones were found, the drug was stopped and symptoms resolved within 1 − 2 days. This study suggests that the risk of ceftriaxone-associated biliary pseudolithiasis should be considered when treating Chinese children.

Safety of ceftriaxone sodium at extremes of age

BACKGROUND

Isolated reports of neonatal and infant deaths associated with ceftriaxone-calcium precipitation in the lungs and kidneys have prompted a recommendation from the US FDA in June 2007 advising that in patients of all ages, calcium-containing solutions should not be administered simultaneously or within 48 h of the last ceftriaxone dose.

OBJECTIVE

To provide a comprehensive review of the literature surrounding the safety of ceftriaxone in the neonatal (< or = 28 days) and geriatric populations (> or = 65 years).

METHODS

Multi-database literature search for original research articles, review articles and case reports pertaining to safety of ceftriaxone in the neonatal and geriatric populations.

RESULTS/CONCLUSIONS

Ceftriaxone should be avoided or significantly minimized in neonates (especially those treated concomitantly with intravenous calcium solutions and those with hyperbilirubinemia), and potentially restricted in the geriatric population treated concomitantly with intravenous calcium.

A symptomatic child with ceftriaxone-associated biliary pseudolithiasis

A 5-year-old boy who had pneumonia was treated in a neighboring hospital. Ceftriaxone was administrated 2 g/day divided into two equal intravenous doses. After 1 week of ceftriaxone therapy, the patient developed abdominal pain. In our hospital, an abdominal sonogram showed a hyperechoic band with postacoustic shadow within the collapsed gallbladder. He was diagnosed with ceftriaxone-associated biliary pseudolithiasis, and ceftriaxone therapy was ceased. On the 8th our hospital day, he again complained of right abdominal pain after supper. A sonogram revealed high-amplitude echoes within the gallbladder neck and common bile duct. Furthermore, bile duct dilatation was observed. He was managed conservatively, after which the symptoms were resolved. On the 11th day, a sonogram showed only sludge within the gallbladder, and on the 13th day, he was discharged from our hospital. It is important for sonographers to recognize the possible occurrence of biliary pseudolithiasis in ceftriaxone-treated patients, especially when a high dose is used in children.

Cholelithiasis and biliary sludge in Downs syndrome patients

CONTEXT AND OBJECTIVE

Although studies have demonstrated increased frequency of gallbladder abnormalities among Downs syndrome (DS) patients in some countries, there is only one paper on this subject in the Brazilian literature. The aim of this study was to demonstrate the prevalence, clinical characteristics and evolution of lithiasis and biliary sludge among DS patients in a maternity and childrens hospital in Rio de Janeiro.

DESIGN AND SETTING

This was a cross-sectional study followed by a retrospective cohort study on all individuals with an ultrasound diagnosis of gallbladder abnormalities.

METHODS

547 DS patients (53.2% male, 46.8% female) attending the Instituto Fernandes Figueira in 2001 underwent abdominal ultrasound examination at ages of between one day and three years (mean: five months). Clinical and ultrasound data were analyzed.

RESULTS

In 50 patients (9.1%), the ultrasound demonstrated gallbladder abnormalities (6.9% lithiasis and 2.1% biliary sludge). Spontaneous resolution was observed in 66.7% of the patients with biliary sludge and 28.9% with lithiasis. Cholecystectomy was carried out on 26.3% of the patients with gallstones.

CONCLUSION

The results from this study and comparison with the literature suggest that DS patients are at risk of developing lithiasis and biliary sludge and should be monitored throughout the neonatal period, even if there are no known risk factors for gallstone formation. Most frequently, these gallbladder abnormalities occur without symptoms and spontaneously resolve in most non-symptomatic patients. DS patients should be monitored with serial abdominal ultrasound, and cholecystectomy is indicated for symptomatic cases or when cholecystitis is present.

[The frequency of pathological ultrasonographic findings of the gallbladder in patients with infectious diseases]

INTRODUCTION

The objective of our study was to establish, through retrospective analysis of sonographic findings obtained by portable ultrasound devices, the frequency of pathological findings of the gallbladder and common bile duct in a randomized group of patients with infectious diseases.

MATERIAL AND METHODS

During five years (January 1, 2000 - December 31, 2004), gallbladder and common bile duct were examined by ultrasonography in 2691 adult patients (1440 males and 1251 females), mean age 48 +/- 17 years, ranging from 17 to 92 years at the Institute of Infectious and Tropical Diseases in Belgrade. The examination included the measurement of size and shape of the gallbladder, its wall and lumen, as well as measurement of caliber and content of the common bile duct. Conventional portable ultrasound devices, ALOKA SSD-500 and SSD-1000 (B-mod) with convex 3.5 and 5 MHz probes were used.

RESULTS

The cholecyst was normal in size (<120 x 50 mm) in 2164 (80.4%), and enlarged in 65 (2.4%) patients. The gallbladder was surgically removed in 163 (6.1%) patients, it was pseudoseptal in 141 (5.2%) and invisible in 44 (1.6%) patients. The gallbladder wall was normal in 2031 (75.5%), thickened in 259 (9.6%) and edematous in 173 (6.4%). Gallbladder calculosis was present in 310 (11.5%), and choledocholithiasis in 13 (0.5%) patients.

CONCLUSION

Development of morphological abnormalities of the gallbladder and common bile duct was frequent in non-selected patients with infectious diseases. The majority of them may be detected by portable ultrasound devices, which makes them rather applicable for large clinical-epidemiological studies.

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.

Biliary sludge and hyperbilirubinemia associated with ceftriaxone in an adult: case report and review of the literature

Ceftriaxone is a commonly used third-generation cephalosporin that has antimicrobial activity against many gram-positive and gram-negative organisms. Generally, ceftriaxone is a safe antibiotic; however, symptomatic biliary sludge has been reported in rare instances, most of which have involved children. It is uncommon for ceftriaxone to cause increases in laboratory indexes, such as bilirubin levels. We describe the case of a 53-year-old man who was treated with intravenous ceftriaxone 2 g every 12 hours. After 7 days of therapy, the patient's liver function test results, including total, direct, and indirect bilirubin levels, increased significantly from baseline, and the patient became jaundiced. A right upper quadrant ultrasound examination revealed biliary sludge and cholelithiasis without sonographic evidence of cholecystitis. Ceftriaxone was thought to be the responsible agent, and it was discontinued. The patient's jaundice subsided, and his liver function test results improved, returning to baseline within 14 days. Clinicians need to be aware of the association of ceftriaxone and biliary pseudolithiasis and hyperbilirubinemia, and monitor accordingly.
