RESUMO
We previously reported that successive pharmaceutical care by oncology pharmacy specialists contributes to quality outpatient chemotherapy. However, there are a few reports regarding such care during immune checkpoint inhibitors (ICIs) treatment, despite increasing patients being treated with ICIs and the profile of immune-related adverse events being quite different from that of the adverse effects of cytotoxic agents. We retrospectively evaluated the effectiveness of continuous pharmaceutical care in outpatient ICI treatment, focusing especially on the period of providing pharmaceutical recommendations. The adoption rate, efficacy, and period of pharmaceutical interventions, such as prescription questions and pharmaceutical recommendations, were evaluated. A total of 3597 ICI administrations (366 patients) were evaluated. We performed 2625 face-to-face medication counseling. A total of 282 prescription questions and 147 pharmaceutical recommendations were conducted. Approximately 70% of the questions were regarding ordering of laboratory examination, and 86.5% of these questions were adopted. Pharmaceutical recommendations were categorized into medication recommendations (81.1%), examination recommendations (10.8%), and recommendation of expert consultation (8.1%). The adoption rate of pharmaceutical recommendations was 96.0, and 70% of the medication recommendations attenuated the symptoms. Finally, the provision rate of pharmaceutical recommendations was significantly higher in the first 3 months after ICI treatment initiation. We found that pharmaceutical care contributes to an improved quality of outpatient ICI treatment, and face-to-face pharmaceutical counseling up to 3 months after ICI treatment initiation is the most important.

Lipids interfere with absorbance measurements conducted using colorimetric methods. To monitor lipemia, some systems measure absorbance using an analyzer. This report describes a novel case of interference with the lipemia index without lipemia. A 64-year-old woman with giant basal cell carcinoma underwent resection and sentinel lymph node biopsy. The patient had been subcutaneously injected with patent blue during sentinel lymph node resection. After surgery, her serum and urine were yellow-green, and the lipemia index, calculated by measuring absorbance at 658 nm (main wavelength) and 694 nm (secondary wavelength) using a JCA-BM8040 chemistry analyzer, was high. The absorbance spectrum of the patient's serum and patent blue solution were compared to determine the cause of the high lipemia index. The patient's serum and the patent blue solution showed absorption at wavelengths between 540 and 698 nm. Moreover, the absorbance was concentration-dependent for patent blue. These results thus indicated that the patient's serum contained patent blue. Here, we report a case wherein patent blue affected the lipemia index. Thus, it must be noted that patent blue injection may yield inaccurate results when evaluating lipemia index.
RESUMO
In this retrospective study, we aimed to identify the risk factors for bleeding in patients after critical illness during edoxaban treatment. Data from patients who received edoxaban after critical illness at the Emergency Department at a tertiary care hospital were obtained from the hospital medical records. Multivariate analysis revealed the risk factors for edoxaban-associated bleeding. Additionally, we developed an edoxaban-associated bleeding score (EAB score) based on these results. The derived EAB score was compared with the HAS-BLED score using receiver operating characteristic (ROC) curve analysis. Bleeding was observed in 42 of 114 patients (36.8%). We identified the following bleeding predictors (odds ratios, 95% confidence interval, score points) using multivariate analysis: concomitant use of antiplatelet agents (6.759, 2.047-22.32, 2 points), concomitant use of P-glycoprotein inhibitors (3.825, 1.484-9.856, 1 point), prothrombin time (PT)% following edoxaban administration of <75% and ≥60% (2.507, 0.788-7.970, 1 point), and PT% following edoxaban administration of <60% (11.23, 3.560-35.42, 3 points). The ROC curve analysis revealed an area under the curve of 0.826 for the EAB score and 0.625 for the HAS-BLED score. Under appropriate edoxaban dosing regimens in patients after critical illness, a combination of antiplatelet agents, P-gp inhibitors, and a low PT% following edoxaban administration were identified as strong risk factors for bleeding.
RESUMO
Denosumab is a fully monoclonal antibody against the receptor activator of nuclear factor kappa-B ligand (RANKL), and prevents skeletal-related events by bone metastasis. Hypocalcemia is the most typical adverse effect of denosumab use. We have developed a management system for the more efficient and safer management of denosumab administration, and evaluated pharmaceutical interventions for the better control of hypocalcemia. All pharmaceutical interventions in the system from April 2016 to March 2020 were retrospectively evaluated. We have also assessed the incidence of hypocalcemia in 158 patients who were administered denosumab for six months or more in the period. A total of 282 pharmaceutical interventions (7.0% of the total administration) were conducted. The most conducted intervention was regarding hypocalcemia, which involved the suspension of the injection and/or the increase of calcium and vitamin D supplement with 65% adoption and 17% temporary treatment suspensions. Other interventions were about hypercalcemia, request of laboratory examination and ordering supplements, dental consultation, and poor renal function. A total of 199 interventions (70.6%) were adopted, with 33 administrations suspended. The frequency of hypocalcemia was 27.8% with just one patient having grade 2 hypocalcemia, suggesting that there were no severe cases. Moreover, hypocalcemia was significantly normalized following pharmaceutical intervention and/or handling by physicians (p=0.02) according to the system. Conversely, the normalization rate in hypercalcemia did not differ according to the countermeasures. In conclusion, pharmaceutical interventions according to our management system benefit safe denosumab treatment, especially in severe hypocalcemia prevention.

Several studies have demonstrated that the activity of system A is upregulated by insulin, osmotic shock and amino acid deprivation. However, the mechanisms are not clear. We carried out studies using L6 rat skeletal muscle cells to clarify the mechanisms of upregulation of system A activity by insulin, osmotic shock and amino acid deprivation. The upregulation was found to be due to an increase in Vmax, not Km. Chloroquine and wortmannin inhibited the upregulation induced by insulin stimulation and amino acid deprivation but not that induced by osmotic shock. On the other hand, cycloheximide and actinomycin D inhibited the upregulation by each stimulation. Moreover, PD98059 and SP600125 inhibited only amino acid deprivation-induced upregulation and SB202190 inhibited only insulin-induced upregulation. Our findings indicate that the mechanisms of upregulation of system A activity by insulin, osmotic shock and amino acid deprivation are different in L6 cells. Western blot and RT-PCR analysis showed an increase in system A at the protein and mRNA levels with each stimulation.

It is important that pharmacists ensure safe chemotherapy implementation. In addition to inspecting chemotherapeutic prescriptions according to patient condition and drug-drug interactions, the management of chemotherapy-induced adverse effects and associated pharmaceutical intervention is one of the most important responsibilities of pharmacists in medical care teams. In May 2016, an oncology pharmacist was set responsible for the specialized, long-term, and successive pharmaceutical care, including instructions about appropriate use of medication at an outpatient chemotherapy center. We evaluated the effectiveness of the continuous pharmaceutical care. The number of medication counseling and associated pharmaceutical interventions increased with time. Specifically, the number of pharmaceutical interventions (prescription questions and pharmaceutical proposals) was 745 (459 and 286, respectively) in the surveillance period, which significantly increased compared to that observed within the same duration before posting an oncology pharmacist. The adoption rate was approximately 70% for prescription questions and 98% for pharmaceutical proposals. We also found that approximately 70% of the proposals attenuated the painful symptoms. Furthermore, approximately 60% of all pharmaceutical interventions were established after the third visit; in particular, approximately 20% of the pharmaceutical proposals were suggested after the sixth visit, indicating that continuous medication counseling results in an increase in pharmaceutical proposals. In conclusion, long-term and successive pharmaceutical care by oncology pharmacy specialists in outpatient chemotherapy contributes to a safe and less onerous chemotherapy implementation, as it has been highly adopted, is effective in many cases, and has been proven to be important for risk management in chemotherapy.
