RESUMEN

In Japan, only few hospitals have pharmacists in their secondary emergency rooms to record medication history and provide drug information in real time. In this study, we investigated the benefits of pharmacist intervention in secondary emergency rooms by comparing the time taken by the pharmacists and non-pharmacists in the emergency room to record the medication history in the electronic medical record and the accuracy of its content. The study period was from September 1 to September 30, 2022, and included patients who were transported to our hospital for emergency care between 9:00 and 16:30. We compared the time taken between the patient's arrival until the recording of their medication history and the accuracy of the record by the emergency room pharmacists and non-pharmacists (paramedics or medical clerks). The study included 58 patients whose medication histories were collected by pharmacists, and 11 patients whose histories were collected by non-pharmacists. For pharmacists, the median time to record medication history in the electronic medical record was 12 min, whereas for non-pharmacists, it was 19 min, which was significantly different (p=0.015). The pharmacists accurately recorded the medication history of 98.3% (57/58) of patients, whereas non-pharmacists accurately recorded it for only 54.5% (6/11) of patients, with a significant difference (p<0.01). We observed that in secondary emergency rooms, when pharmacists were responsible for recording the patients' medication histories, it resulted in rapid and accurate sharing of medication history.

RESUMEN

BACKGROUND: Bucolome is a non-steroidal anti-inflammatory drug and uricosuric agent, currently used only in Japan. It is known to induce drug interactions by inhibiting cytochrome P450 (CYP) 2C9. It is often used to enhance the anticoagulant effect of warfarin by utilizing its drug interactions. There are only a few reports on drug interactions of bucolome and the mechanism remain poorly understood. CASE PRESENTATION: An 81-year-old woman with a history of type 2 diabetes mellitus was taking glimepiride 2 mg/day and voglibose 0.6 mg/day. After hospitalization, the patient underwent surgical aortic valve replacement surgery (day 0). Glimepiride and voglibose were resumed on the second postoperative day (day 2), and warfarin was started to prevent thromboembolism. Since the prothrombin time-international normalized ratio on day 9 was low at 1.24, 300 mg/day of bucolome was added to enhance the effect of warfarin. A gradual decrease in blood glucose levels was observed from the day after bucolome administration was initiated. Hypoglycemia in the 56-57 mg/dL range occurred before lunch and dinner on the 6th day (day 14) of bucolome administration, due to which voglibose was discontinued. Hypoglycemia below 70 mg/dL was not observed thereafter, and the general condition of the patient was stable. CONCLUSIONS: Based on the clinical course and literature review, we believe that hypoglycemia in the present case was due to a drug interaction, caused by inhibition of CYP2C9 by bucolome and competitive inhibition of CYP2C9 by warfarin, which affected the pharmacokinetics of glimepiride. The possibility of hypoglycemia due to drug interactions should be considered by physicians, when bucolome is included to enhance the effect of warfarin, in patients taking glimepiride.

RESUMEN

BACKGROUND Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a potentially life-threatening syndrome comprising severe skin eruption, fever, eosinophilia, lymphadenopathy, and involvement of internal organs. Here, we describe a case of DRESS syndrome caused by cross-reactivity between vancomycin and subsequent teicoplanin administration. CASE REPORT A 79-year-old male was admitted to our hospital for the treatment of injuries incurred in a traffic accident. Eosinophilia and lung dysfunction appeared after vancomycin administration. These symptoms were improved temporarily by withdrawal of vancomycin and administration of corticosteroid, but exacerbated by subsequent teicoplanin administration. These symptoms disappeared after discontinuation of teicoplanin. Based on comprehensive assessment of the overall clinical course, we judged that DRESS syndrome was induced by cross-reactivity between vancomycin and subsequent teicoplanin administration. Using the European Registry of Severe Cutaneous Adverse Reactions (RegiSCAR) scoring system, we categorized DRESS syndrome related to vancomycin and teicoplanin as "probable." We describe, for the first time, DRESS syndrome (defined using the RegiSCAR scoring system) caused by cross-reactivity between vancomycin and subsequent teicoplanin administration. CONCLUSIONS Clinicians should be aware that DRESS syndrome can be induced by cross-reactivity between vancomycin and teicoplanin.
