Efficacy, safety and cost of emicizumab prophylaxis in haemophilia A patients with inhibitors: A nationwide observational study in Taiwan.

INTRODUCTION: Emicizumab mimicking the cofactor function of activated factor VIII (FVIII) restores haemostasis. METHODS: This nationwide observational study aimed to retrospectively investigate efficacy, safety, and cost in 1 year before and up to 3 years after emicizumab prophylaxis for haemophilia A (HA) patients with FVIII inhibitors. RESULTS AND DISCUSSION: A total of 39 severe HA patients with a median age of 23.0 years were enrolled. The median historical peak FVIII inhibitor titre was 174.2 BU/mL with an interquartile range of 56.5-578.8 BU/mL. The median annualized bleeding rate reduced from 24 to 0 events in the first year after emicizumab prophylaxis (p < .01) and sustained in the second and third years. The median annualized joint bleeding rate reduced to 0 and maintained up to 3 years (p < .01). Twenty-seven patients (69.2%) had target joints before emicizumab prophylaxis and only seven patients (17.9%) of them had target joints after prophylaxis. Medical costs, including cost of haemostatic therapy, frequency of outpatient department visits, emergency room visits and hospital admission, were significantly reduced after emicizumab prophylaxis (p < .01). FVIII inhibitor titre decreased after emicizumab prophylaxis. Overall, three (7.7%) patients experienced 202 grade 1 drug-related adverse events after emicizumab prophylaxis. No serious adverse events were reported during emicizumab prophylaxis period. The adherence to emicizumab prophylaxis was 100% up to 3 years. CONCLUSIONS: HA patients with FVIII inhibitors treated with emicizumab prophylaxis resulted in a significant reduction in treated bleeds and associated costs. No new safety events were observed.

The impact of a medication reconciliation programme at geriatric hospital admission: A pre-/postintervention study.

AIMS: The aim of this study was to improve medication reconciliation and reduce the occurrence of duplicate prescriptions by pharmacists and physicians within 72 hours of hospital admission using an intelligent prescription system combined with the National Health Insurance PharmaCloud system to integrate the database with the medical institution computerized physician order entry (CPOE) system. METHODS: This 2-year intervention study was implemented in the geriatric ward of a hospital in Taiwan. We developed an integrated CPOE system linked with the PharmaCloud database and established an electronic platform for coordinated communication with all healthcare professionals. Patients provided written informed consent to access their PharmaCloud records. We compared the intervention effectiveness within 72 hours of admission for improvement in pharmacist medication reconciliation, increased at-home medications documentation and decreased costs from duplicated at-home prescriptions. RESULTS: The medication reconciliation rate within 72 hours of admission increased from 44.0% preintervention to 86.8% postintervention (relative risk = 1.97, 95% confidence interval [CI]: 1.69-2.31; P < .001). The monthly average of patients who brought and took home medications documented in the CPOE system during hospitalization increased by 7.54 (95% CI 5.58-20.49, P = .22). The monthly average of home medications documented increased by 102.52 (95% CI 38.44-166.60; P = .01). Savings on the monthly average prescription expenditures of at-home medication increased by US$ 2,795.52 (95% CI US$1310.41-4280.63; P < .01). CONCLUSION: Integrating medication data from PharmaCloud to the hospital's medical chart system improved pharmacist medication reconciliation, which decreased duplicated medications and reduced in-hospital medication costs.

Assessment of the effects of walking as an exercise intervention for children and adolescents with cancer: A feasibility study.

PURPOSE: To examine the effects of walking exercise on exercise tolerance, fatigue, sleep quality, and quality of life (QOL) for children and adolescents with cancer. METHODS: A 6-week walking exercise regimen was implemented in pediatric hematological and oncological wards and in clinics of a medical center in Taiwan. A 6-min walk test (6MWT), fatigue, sleep quality, and QOL were measured at baseline and for six subsequent weeks. RESULTS: Adherence to the walking exercise regimen was achieved by 72-89% of the participants in this study. Significant improvements in exercise tolerance were observed after two weeks and they continued through week 6 (F = 17.07, p < 0.001). Both cognitive fatigue and general fatigue were significantly improved after six weeks of walking exercise (t = 2.41, p = 0.02; t = 2.76, p = 0.01), while sub-scores for sleep/rest fatigue did not improve. No significant impact on sleep quality or QOL was observed. CONCLUSIONS: Walking exercise is a feasible and tolerable intervention that should be considered for children and adolescents with cancer. Here, a 6-week walking exercise regimen increased exercise tolerance and improved fatigue. We recommend that walking exercise should be promoted during hospitalization and at home to alleviate fatigue.

Immune tolerance induction therapy for patients with hemophilia A and FVIII inhibitors particularly using low-dose regimens.

BACKGROUND: Inhibitory antibodies against infused clotting factor VIII concentrates (FVIII) developed in 20-30% of patients with hemophilia A. Bypass therapy may control the bleeds in patients with FVIII inhibitors, however, immune tolerance induction (ITI) therapy is the only proven modality for eradicating FVIII inhibitors. Since the cost of high-dose (200 IU/kg) ITI is extremely expansive, we conducted this study to identify whether low-dose ITI can be an alternative strategy besides high-dose ITI or bypass therapy. PROCEDURE: Patients with hemophilia A and FVIII inhibitors treated by ITI in Kaohsiung Medical University Hospital from January 2000 to January 2010 were enrolled. Regimens of ITI therapy included high-dose (100 IU/kg) and low-dose (30-50 IU/kg). RESULTS: High-dose ITI therapy for two high responders (HRs) and low-dose ITI therapy for three HRs and all low responders (LRs) were performed. Complete tolerance was achieved in 2 HRs with high-dose regimen, and in one HR and 19 LRs with low-dose regimens. We administered low-dose ITI combined with immune suppressants treatment for one of the patient with extremely high FVIII inhibitor titers and the inhibitor level markedly declined and no spontaneous bleeding episode was noticed during the treatment period. CONCLUSIONS: The outcome of ITI in our study was satisfactory without clinically significant complications. Low-dose ITI regimens can effectively treat patients with high responder inhibitors, including one patient with extremely high inhibitor levels over 700 BU. Low-dose ITI may be an alternative modality for FVIII inhibitors management, especially in countries with limited resources.
