Neurologic Adverse Events Associated with Voriconazole Therapy: Report of Two Pediatric Cases.

ABSTRACT: Although voriconazole, a triazole antifungal, is a safe drug, treatment with this agent is associated with certain adverse events such as hepatic, neurologic, and visual disturbances. The current report presents two cases, one a 9-year-old boy and the other a 17-year-old girl, who experienced neurologic side effects associated with voriconazole therapy. Our aim is to remind readers of the side effects of voriconazole therapy in order to prevent unnecessary investigations especially for psychological and ophthalmologic problems. The first case was a 9-year-old boy with cystic fibrosis and invasive aspergillosis that developed photophobia, altered color sensation, and fearful visual hallucination. The second case was a 17-year-old girl with cystic fibrosis and allergic bronchopulmonary aspergillosis, and she experienced photophobia, fatigue, impaired concentration, and insomnia, when the dose of voriconazole therapy was increased from 12 mg/kg/day to 16 mg/kg/day. The complaints of the two patients disappeared after discontinuation of voriconazole therapy. Our experience in these patients reminded us of the importance of being aware of the neurologic adverse events associated with voriconazole therapy in establishing early diagnosis and initiating prompt treatment. In addition, although serum voriconazole concentration was not measured in the present cases, therapeutic drug monitoring for voriconazole seems to be critically important in preventing neurologic side effects in pediatric patients.

Project description:BackgroundChronic anticoagulation has been demonstrated to be a risk factor for GI bleeding (GIB) in patients undergoing endoscopic procedures.ObjectiveThe aim of this study was to determine the incidence of GIB prospectively in a large cohort of patients enrolled in the Clinical Outcomes Research Initiative (CORI) database.DesignAnticoagulated patients undergoing endoscopic procedures were interviewed by phone 30 to 45 days after the procedure to determine potential adverse events and management of warfarin therapy in the periendoscopic period.SettingParticipating CORI sites, Stanford University Hospital, Veterans Administration Palo Alto Health Care System.Main outcome measurementPostprocedural hemorrhagic or thrombotic events.ResultsThirteen CORI sites agreed to participate, including 120,886 procedures in 95,807 patients. We contacted 929 patients on warfarin therapy and enrolled 483 patients (52%). The majority of the patients were men with atrial fibrillation undergoing colonoscopy. Warfarin was temporarily suspended in 437 (90%) of the patients before the procedure, and 114 (22%) received periprocedural heparin therapy. There were 10 major hemorrhagic events (2%), and the rate of hemorrhage was not higher in the patients receiving periprocedural heparin therapy (P = .1). However, polypectomy was a risk factor for postprocedural hemorrhage (P = .02). One fatal stroke (0.2%) occurred in a patient 2 weeks after endoscopy; however, information regarding warfarin management was not available.LimitationsSmall number of enrolled patients and lack of control group. Lack of information regarding prothrombin time before procedure, concurrent antiplatelet agents, and timing of bleeding in 50% of the cases. The study was underpowered to definitively conclude benefits of current guidelines regarding thrombosis or bleeding.ConclusionsPostprocedural hemorrhagic events were not increased in anticoagulated patients. Most patients receiving bridging therapy were managed according to current society guidelines.

Project description:Background and objectivesMajor adverse kidney events, a composite of death, new kidney replacement therapy, or persistent kidney dysfunction, is a potential patient-centered outcome for clinical trials in sepsis-associated kidney injury. We sought to determine the incidence of major adverse kidney events within 30 days and validate this end point in pediatric sepsis.Design, setting, participants, & measurementsWe conducted a retrospective observational study using the Pediatric Health Information Systems Plus database of patients >6 months to <18 years old with a diagnosis of severe sepsis/septic shock; orders for bacterial blood culture, antibiotics, and at least one fluid bolus on hospital day 0/1; and known hospital disposition between January 2007 and December 2011. The primary outcome was incidence of major adverse kidney events within 30 days. Major adverse kidney events within 30 days were validated against all-cause mortality at hospital discharge, hospital length of stay, total hospital costs, hospital readmission within 30 days and 1 year, and lowest eGFR between 3 months and 1 year after discharge. We reported incidence of major adverse kidney events within 30 days with 95% confidence intervals using robust SEM and used multivariable logistic regression to test the association of major adverse kidney events within 30 days with hospital costs and mortality.ResultsOf 1685 admissions, incidence of major adverse kidney events within 30 days was 9.6% (95% confidence interval, 8.1% to 11.0%), including 4.5% (95% confidence interval, 3.5% to 5.4%) death, 1.7% (95% confidence interval, 1.1% to 2.3%) kidney replacement therapy, and 5.8% (95% confidence interval, 4.7% to 6.9%) persistent kidney dysfunction. Patients with versus without major adverse kidney events within 30 days had higher all-cause mortality at hospital discharge (28% versus 1%; P<0.001), higher total hospital costs ($61,188; interquartile range, $21,272-140,356 versus $28,107; interquartile range, $13,056-72,697; P<0.001), and higher proportion with eGFR<60 ml/min per 1.73 m2 between 3 months and 1 year after discharge (19% versus 4%; P=0.001). Major adverse kidney events within 30 days was not associated with length of stay or readmissions.ConclusionsIn children with sepsis, major adverse kidney events within 30 days are common, feasible to measure, and a promising end point for future clinical trials.
