RESUMO
Key Clinical Message: Even in a country where vancomycin-resistant enterococcus is rare, multidrug-resistant organism precautions are necessary when admitting patients with a history of medical exposure in other countries. On admission, screening is necessary and if infection is confirmed, a multidisciplinary approach involving different specialists is required. Abstract: The patient was a 49-year-old Japanese female living in the United States. Total pelvic exenteration for cervical carcinoma, Miami pouch formation, and ileostomy had been performed in the United States. She returned to Japan to undergo postoperative adjuvant chemotherapy. Fever and abdominal pain occurred 42 days after surgery. She consulted the fever outpatient clinic, and a diagnosis of urinary retention-associated acute renal failure and pyelonephritis was made. We detected vancomycin-resistant enterococcus on urine/blood culture 5 days after admission. Infection control measures were implemented, and the ward was closed for 3 days. We administered linezolid, which was effective for pyelonephritis and bacteremia.
RESUMO
Direct oral anticoagulants (DOACs) are available for nonvalvular atrial fibrillation patients. The advantage of DOACs is that regular anticoagulation monitoring is not required. However, adherence to the recommended regimen is essential. We investigated the association between medication adherence and the risk of cerebral infarction in patients taking DOACs. Patients admitted to any of the participating hospitals for cerebral infarction from September 2018 to February 2020 and prescribed DOACs before admission were defined as the case group, and patients hospitalized for diseases other than cerebral infarction, except for bleeding disorders, and prescribed DOACs before admission were defined as the control group. A nested case-control study was adapted, and 58 and 232 patients were included in the case and control groups, respectively. Medication adherence was assessed by the pharmacists through standardized interviewing. The adjusted odds ratio for the risk of cerebral infarction for low-adherence patients (<80% adherence rate) against good-adherence patients (100% adherence rate) was 9.69 (95% confidence interval, 3.86-24.3; p < 0.001). The patients' age and other background characteristics were not found to be risk factors for cerebral infarction. In conclusion, low adherence is a risk factor for cerebral infarction in patients taking DOACs. Pharmacists should focus on maintaining ≥80% adherence to DOAC therapy to prevent cerebral infarction.
