RESUMO
Anorexia Nervosa (AN) has always been prevalent in adolescents. During the COVID-19 pandemic, the eating disorder community across the world has noted a sharp increase in adolescent patients with AN and the severity of medical compromise. Rarely seen sequelae have become increasingly more common. This case report describes two previously healthy female adolescents with severe malnutrition due to AN admitted for nutritional stabilization who exhibited paranoid delusions responsive to thiamine and olanzapine. Though neither exhibit the full triad or all the Caine criteria for Wernicke's Encephalopathy (WE), the triad will not present completely in most patients with WE, especially in the pediatric population. Having one symptom of the triad is indicative of WE. Due to the decreased number of clinical criteria for Wernicke's encephalopathy coupled with the lack of typical brain MRI findings found in these patients, we recommend a high index of suspicion for WE and investigation with thiamine. Thiamine supplementation should be standard care in AN with oral supplementation in stable conditions. In the case of refeeding syndromes, preventative parenteral thiamine 100 mg IV qd, and in the case of thiamine deficiency, thiamine 500 mg IV TID.
RESUMO
PURPOSE: Results of a study of rates of acute kidney injury (AKI) in pediatric patients treated with vancomycin plus piperacillin-tazobactam or vancomycin plus alternative antipseudomonal ß-lactams (APBLs) are reported. METHODS: A retrospective, single-center cohort study was performed. Pediatric patients were included in the study cohort if they received combination therapy for at least 48 hours, had documented baseline and follow-up serum creatinine levels, and had a documented serum vancomycin trough concentration. The primary outcome was the frequency of AKI, defined as a 50% or greater increase in serum creatinine concentration from baseline or an increase of at least 0.5 mg/dL from baseline. The secondary outcome was time to AKI onset. RESULTS: A total of 474 patients were included. Among 100 patients who received vancomycin plus piperacillin-tazobactam, the rate of AKI was higher than the rate in the group treated with vancomycin plus alternative APBLs (27% versus 7%, p < 0.0001). The median time to AKI onset was shorter in the piperacillin-tazobactam group versus the alternative APBL group (3.8 versus 7.9 days, p = 0.0065). Patients who were administered piperacillin-tazobactam were almost 6 times as likely to develop AKI (odds ratio [OR], 5.955; 95% confidence interval [CI], 2.774-12.784), and patients who had a maximum vancomycin trough concentration greater than 20 mg/L were 7.5 times as likely to develop AKI (OR, 7.552; 95% CI, 3.625-15.734). CONCLUSION: Pediatric patients treated with concomitant vancomycin and piperacillin-tazobactam had a higher rate of AKI, with faster AKI onset, than those who received vancomycin in combination with other APBLs.
