Toward Genetic Testing of Rivaroxaban? Insights from a Systematic Review on the Role of Genetic Polymorphism in Rivaroxaban Therapy.

BACKGROUND: Investigations into the rivaroxaban response from the perspective of genetic variation have been relatively recent and wide in scope, whereas there is no consensus on the necessity of genetic testing of rivaroxaban. Thus, this systematic review aims to thoroughly evaluate the relationship between genetic polymorphisms and rivaroxaban outcomes. METHODS: The PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Chinese databases were searched to 23 October 2022. We included cohort studies reporting the pharmacogenetic correlation of rivaroxaban. Outcomes measured included efficacy (all-cause mortality, thromboembolic events and coagulation-related tests), safety (major bleeding, clinically relevant non-major bleeding [CRNMB] and any hemorrhage), and pharmacokinetic outcomes. A narrative synthesis was performed to summarize findings from individual studies according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the reporting guideline for Synthesis Without Meta-Analysis. RESULTS: A total of 12 studies published between 2019 and 2022 involving 1364 patients were included. Ten, one, and six studies focused on the ABCB1, ABCG2, and CYP gene polymorphisms, respectively. Pharmacokinetic outcomes accounted for the majority of the outcomes reported (n = 11), followed by efficacy (n = 5) [including prothrombin time (PT) or international normalized ratio (n = 3), platelet inhibition rate (PIR) or platelet reactivity units (PRUs; n = 1), thromboembolic events (n = 1)], and safety (n = 5) [including major bleeding (n = 2), CRNMB (n = 2), any hemorrhage (n = 1)]. For ABCB1 gene polymorphism, the relationship between PT and ABCB1 rs1045642 was inconsistent across studies, however there was no pharmacogenetic relationship with other efficacy outcomes. Safety associations were found in ABCB1 rs4148738 and major bleeding, ABCB1 rs4148738 and CRNMB, ABCB1 rs1045642 and CRNMB, and ABCB1 rs2032582 and hemorrhage. Pharmacokinetic results were inconsistent among studies. For ABCG2 gene polymorphism, no correlation was observed between ABCG2 rs2231142 and dose-adjusted trough concentration (Cmin/D). For CYP gene polymorphisms, PIR or PRUs have a relationship with CYP2C19 rs12248560, however bleeding or pharmacokinetic effects did not show similar results. CONCLUSIONS: Currently available data are insufficient to confirm the relationship between clinical or pharmacokinetic outcomes of rivaroxaban and gene polymorphisms. Proactive strategies are advised as a priority in clinical practice rather than detection of SNP genotyping. CLINICAL TRIALS REGISTRATION: PROSPERO registration number CRD42022347907.

The Effect of Genetic Variation on the Sensitivity to Opioid Analgesics in Patients With Postoperative Pain: An Updated Meta-analysis.

BACKGROUND: Responsiveness to opioid analgesics differs among patients with acute postoperative pain. OBJECTIVE: Our study presents the most recent evidence on the effect of genetic variations on postoperative pain, opioid consumption, nausea, and vomiting in patients treated with opioids. STUDY DESIGN: An updated systematic review and meta-analysis on the association between single-nucleotide polymorphisms and opioids administered to patients with acute postoperative pain. METHODS: PubMed, Embase, ISI Web of Science, and the Cochrane Library databases were searched for articles published from February 1, 2014, through December 31, 2021. RESULTS: Added to the previous meta-analysis, 39 studies (a total of 7,455 patients) were included in the final meta-analysis. Highlights of the findings include: 1) human µ-opioid receptor gene 118G allele carriers required more opioids during the first postoperative 24 hours (standard mean difference [SMD] = -0.27; 95% CI,-0.40 to -0.14; P < 0.0001) and 48 hours (SMD = -0.52; 95% CI, -0.83 to -0.20; P = 0.001), and reported higher pain scores during the first 24 hours but not at the 48-hour postoperative period (SMD = -0.09, 95% CI, -0.15 to -0.03; P = 0.002) compared to homozygous 118AA patients. 2) patients with the CYP3A4 *1G allele required fewer opioids during the first 24-hour postoperative period (SMD = 0.59; 95% CI, 0.05 to 1.14; P = 0.03) compared to patients with the homozygous CYP3A4*1/*1 allele. 3) Adenosine triphosphate-binding cassette subfamily B member-1 (ABCB1) 3435T allele carriers required more opioids during the 48-hour postoperative period (SMD = -0.21; 95% CI, -0.38 to -0.04; P = 0.02) compared to homozygous CC carriers. 4) Catechol-O-methyl transferase 158A allele carriers required fewer opioids during the first 24-hour postoperative period (SMD = 0.33; 95% CI, 0.15 to 0.51; P = 0.0004) compared to homozygous GG carriers. No significant differences were observed in patients with CYP2D6*10 and ABCB1 G2677A/T genetic polymorphisms. LIMITATIONS: Several loci were not analyzed in detail due to insufficient clinical data. Furthermore, nongenetic factors that affected analgesic efficacy and the clinical outcome of postoperative pain were not discussed and were not the aim of this meta-analysis. CONCLUSIONS: In combination with previous systematic reviews and meta-analyses, our results indicate that the A118G allele variant of OPRM1 and the *1*1G allele variant of CYP3A4 have a profound influence on individual differences in opioid reactivity in patients with postoperative pain. Our results, together with the identification of additional single nucleotide polymorphisms in future studies, may provide a theoretical basis for precise clinical analgesia. KEY WORDS: Single nucleotide polymorphism, postoperative pain, opioid, meta-analysis.

A prediction model for severe hematological toxicity of BTK inhibitors.

Bruton's tyrosine kinase inhibitor (BTKi) has revolutionized the treatment of B-cell lymphomas. However, BTKi-related hematological toxicity hinders treatment continuity and may further affect clinical efficacy. To identify risk factors and predict the likelihood of BTKi-related hematological toxicities, we constructed and validated a prediction model for severe hematological toxicity of BTKi. Approved by the hospital medical science research ethics committee (No. M2022427), we collected real-world data in patients treated with BTKi from a Lymphoma Research Center in China. The outcome of interest was severe hematological toxicity caused by BTKi. 36 candidate variables were categorized into demographics, diagnostic and treatment information, laboratory data, and medical history. The study sample was randomly divided into training (70%) and validation (30%) sets. We developed and compared the performance of various modelling methods, including decision tree (DT), random forest (RF), gradient boosting decision tree (GBDT), extreme gradient boosting (XGBoost), light gradient boosting machine (LightGBM), and logistic regression (LR). Finally, we constructed a Web-calculator of the optimal model to estimate the risk of hematological toxicity. This study was designed, conducted and reported strictly in compliance with the TRIPOD checklist. Data from a total 121 patients were included [median age, 65 years (range, 56-73 years); 74 (61.15%) men; 47 (38.84%) severe hematological toxicity]. The XGBoost model demonstrated better overall properties than other models, achieving high discrimination (AUC: 0.671; accuracy: 0.730; specificity: 0.913) and clinical benefit. The following 10 variables were used to develop the XGBoost model: white blood cell count (WBC), neutrophil count (Neut), red blood cell count (RBC), platelet count (PLT), fibrinogen (Fib), total protein (TP), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), gender and type of BTKi. SHAP values demonstrated insightful associations between these variables and hematological toxicity. Finally, to facilitate clinical and research use, we also deploy the XGBoost model on a web-calculator for free access. The XGBoost model with promising accuracy was developed to predict the severe hematological toxicity of BTKi. It helps to strengthen the proactive monitoring and management of patients with hematological toxicity, and thus achieve long-term continuous BTKi treatment.

Toward therapeutic drug monitoring of citalopram in depression? Insights from a systematic review.

Background: Within the framework of individualized psychopharmacotherapy, therapeutic drug monitoring (TDM) has gained increasing relevance. In the absence of high-quality evidence, the TDM of citalopram (CIT) and the recommended therapeutic ranges of the plasma concentrations have been proposed by guidelines. However, the correlation between the plasma concentration of CIT and treatment outcomes has not been well established. Therefore, the aim of this systematic review was to evaluate the relationship between plasma CIT concentration and treatment outcomes in depression. Research design and methods: PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Chinese databases (CNKI, Wanfang Data and Sinomed) were searched up to August 6, 2022. We included clinical studies evaluating the correlation between the plasma CIT concentration and treatment outcomes in patients with depression receiving CIT treatment. Outcomes measured included efficacy, safety, medication adherence, and cost-related outcomes. A narrative synthesis was performed to summarize findings from individual studies. This study was performed according to the Preferred Reporting Items for Systematic Reviews, Meta-Analysis (PRISMA) and the reporting guideline for Synthesis without meta-analysis (SWiM). Results: Eleven studies involving 538 patients were included in total. The reported outcomes were mainly efficacy (n = 11) and safety (n = 3); one study reported the duration of hospitalization, and no study reported medication adherence. Regarding the efficacy outcomes, three studies revealed the plasma CIT concentration-response relationship and proposed a lower limit of 50 or 53 ng/mL, whereas this was not found in the rest of the studies. Regarding adverse drug events (ADEs), one study reported more ADEs in the low-concentration group (<50 ng/mL vs. >50 ng/mL), which is not convincing from the perspective of pharmacokinetics/pharmacodynamics. Regarding the cost-related outcomes, only one study reported that the high CIT concentration group (≥50 ng/mL) contributed to shortening the hospitalization duration, but it did not provide detailed information, including direct medical expenses and multiple potential factors contributing to longer hospital stays. Conclusions: A definite correlation between plasma concentration and clinical or cost-related outcomes of CIT cannot be drawn, whereas a tendency toward improved efficacy in patients with plasma concentration above 50 or 53 ng/mL was suggestive from limited evidence.

Pan-Cancer Analysis of Voltage-Dependent Anion Channel (VDAC1) as a Cancer Therapeutic Target or Diagnostic Biomarker.

The voltage-dependent anion channel 1 (VDAC1), a pore protein located in the outer mitochondrial membrane, has been confirmed to be related to cancer in cell or animal evidence. However, there is no available pan-cancer analysis of VDAC1. Herein, we investigated the potential roles of VDAC1 in tumorigenesis and progression based on the Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO), and Clinical Proteomic Tumor Analysis Consortium (CPTAC) datasets. The expression of VDAC1 increased in most cancers, and the upregulation of VDAC1 distinctly correlated with the poor prognosis in patients, including breast invasive carcinoma, cervical squamous cell carcinoma, pancreatic adenocarcinoma, lung adenocarcinoma, and skin cutaneous melanoma. We also found VDAC1 S104 phosphorylation raised in various cancers, such as breast cancer, colon cancer, and lung adenocarcinoma. Moreover, the expression of VDAC1 was related to the estimated infiltration value of cancer-associated fibroblasts in bladder urothelial carcinoma, colon adenocarcinoma, kidney renal papillary cell carcinoma, and testicular germ cell tumors. At last, we showed that VDAC1-related oxidative phosphorylation and metabolic regulation may partially explain its association with tumorigenesis and progression. Taken together, this pan-cancer analysis provides relatively comprehensive information on the potential value of VDAC1 as a prognostic biomarker and therapeutic target.

Risk of bleeding associated with BTK inhibitor monotherapy: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: The bleeding risk associated with Bruton's tyrosine kinase inhibitor (BTKi) monotherapy remains to be understood. This systematic review aims to evaluate BTKi monotherapy related bleeding risk. RESEARCH DESIGN AND METHODS: PubMed, Embase, and CENTRAL were searched up to 5 December 2021. We included randomized controlled trials (RCTs) comparing BTKi monotherapy with control drugs, or comparing different BTKi monotherapies. RESULTS: 10 studies with 3139 patients were included. Ibrutinib (vs. control drugs) significantly increased the risk of overall bleeding and major bleeding (RR = 2.22, 95% CI 1.80-2.75, P < 0.00001; RR = 1.80, 95% CI 1.02-3.18, P = 0.04, respectively). Acalabrutinib (vs. control drugs) had a significantly increased overall bleeding risk (RR = 3.45, 95% CI 2.39-4.99, p < 0.00001). A significant difference was found in overall bleeding between ibrutinib and acalabrutinib (RR = 1.35, 95% CI 1.11-1.64, P = 0.002). Compared to zanubrutinib, ibrutinib tended to increase the risk of major bleeding (RR = 1.55, 95% CI 0.57-4.18, P = 0.39). CONCLUSIONS: Ibrutinib and acalabrutinib (vs. control drugs) have a higher risk of bleeding and overall bleeding, respectively. Limited evidence suggests that ibrutinib (vs. acalabrutinib) significantly increases overall bleeding risk, but the differences are not observed in other comparisons.

Toward Therapeutic Drug Monitoring of Lenalidomide in Hematological Malignancy? Results of an Observational Study of the Exposure-Safety Relationship.

Objective: Continuous lenalidomide (LEN) therapy is important to achieve a therapeutic effect in patients with multiple myeloma (MM) and non-Hodgkin lymphoma (NHL). However, despite dose adjustment according to kidney function, many patients discontinue LEN therapy because of hematological toxicity. To date, therapeutic drug monitoring (TDM) of LEN has not been performed in oncology, and no target concentration level has been yet defined. The aim of this study was to evaluate the exposure-safety relationship of LEN and determine the target concentration for toxicity. Materials and Methods: A prospective observational study was designed and implemented. Blood samples were collected at 0.5 h (trough concentration, Cmin) before oral administration and 1 h (C1h) thereafter on the day. Clinical data were gathered from patients' medical records and laboratory reports. Outcome measures of hematological toxicity were defined by the Common Terminology Criteria for Adverse Events. The concentration values were dichotomized by receiver operating characteristic (ROC) curve analysis, and the association between exposure and outcome was determined using the logistic regression model. Results: Out of the 61 patients enrolled in this study, 40 (65.57%) had MM, and 21 (34.43%) had NHL. Hematological toxicity was reported in 15 (24.59%) patients. The LEN Cmin showed remarkable differences (p = 0.031) among patients with or without hematological toxicity, while no association between C1h values and toxicity was noted (p>0.05). By ROC analysis, a Cmin threshold of 10.95 ng/mL was associated with the best sensitivity/specificity for toxicity events (AUC = 0.687; sensitivity = 0.40; specificity = 0.935). By multivariate logistic regression, an LEN Cmin below 10.95 ng/mL was associated with a markedly decreased risk of hematological toxicity (<10.95 ng/mL vs. >10.95 ng/mL: OR = 0.023, 95% CI = 0.002-0.269; p = 0.003). Conclusions: We demonstrate that the LEN trough concentration correlates with hematological toxicity, and the Cmin threshold for hematological toxicity (10.95 ng/mL) is proposed. Altogether, LEN TDM appears to be a new approach to improve medication safety and achieve continuous treatment for patients with NHL or MM in routine clinical care.

Knowledge, Attitudes and Practice of Healthcare Providers, Healthcare Regulatory Practitioners and Patients Toward Biosimilars in China: Insights From a Nationwide Survey.

Objective: With increasing numbers of biosimilars entering the market or in the approval pipeline in China, understanding the current awareness and attitudes of biosimilars still remains the first step to promote uptake. This study aims to investigate the knowledge, attitudes and practices (KAP) of multiple stakeholders toward biosimilars, including healthcare providers (HCPs), healthcare regulatory practitioners and patients, and to provide practical information for future uptake of biosimilars in China. Methods: This nationwide cross-sectional online survey was conducted in mainland China. The questionnaire with a high level of reliability and validity was designed based on previous studies and clinical questions in the Clinical Practice Guideline for Clinical Application of Biosimilars. Logistic regression model was employed to identify possible impact factors, and Spearman's rank correlation test was used to identify the correlation between knowledge and attitudes. Chi-squared test was used to compare the differences between different stakeholders. Results: Overall, 599 valid respondents were recruited, of whom 77.63%, 7.01% and 15.36% were HCPs, healthcare regulatory practitioners and patients, respectively. A total of 504 respondents who had heard of biosimilars were included in the KAP analysis. 76.70% of HCPs, 90.24% of healthcare regulatory practitioners and 50.98% of patients had good knowledge about the definition, while less familiarity with the development process and regulations on interchangeability and indication extrapolation was found in the former two groups. For attitudes toward biosimilars, an overall lack of positivity was shown, as only 18.20% HCPs, 14.63% healthcare regulatory practitioners and 23.53% patients were classified as having positive attitudes. More specifically, most respondents were positive about the influence of payment policy on the uptake of biosimilars, but they showed a neutral attitude toward the clinical medication and interchangeability of biosimilars. Efficacy, safety, immunogenicity, interchangeability and indication extrapolation are major concerns when utilizing biosimilars. Regarding practice, our study showed an inadequate utilization of biosimilars in China. Several further suggestions on the regulation of biosimilars were proposed by healthcare regulatory practitioners. Conclusions: There is still plenty of room for improvement of knowledge, attitudes and practice toward biosimilars among multiple stakeholders in China, which can be improved through high-quality real world evidence, educational programs and other effective measures directed towards barriers.

Long-Term Safety of Rituximab in DLBCL Patients With Hepatitis B-Related Cirrhosis: A Retrospective Case Series.

Objective: Chemotherapy regimens containing rituximab (RTX) have been extensively used to treat diffuse large B cell lymphoma (DLBCL). However, data looking at long-term safety of DLBCL patients with hepatitis B-related cirrhosis are still lacking. This study aims to report the safety and outcomes of RTX administration in DLBCL patients with hepatitis B-related cirrhosis. Methods: A retrospective case series was designed and implemented, using data from January 1, 2011 to December 31, 2020. Consecutive patients who were diagnosed with DLBCL and hepatitis B-related cirrhosis receiving RTX treatment were included. The primary outcomes included HBV reactivation, hepatitis flares or abnormal liver function. Survival status, the secondary outcome measure, was observed until death, loss to follow-up, or the end of follow-up, whichever occurred first. Results: A total of 8 DLBCL patients combined with hepatitis B-related cirrhosis were included in this study [4 men; median age 62.5 years (range, 44-77 years); median RTX-containing regimen course 5 (range, 2-11)]. Of them, 6 patients had current HBV infection with HBsAg-positive and anti-HBc-positive, whereas 2 patients had previously resolved HBV infection with HBsAg-negative and anti-HBc-positive. The HBV reactivation was observed in only one patient, who received 11 courses of RTX-containing immunochemotherapies within 15 months. No hepatitis flares or abnormal liver function occurred in any patients included. All patients received standardized antiviral therapy for a lifelong time. Of 8 patients included, 3 patients died, and 1 patient was lost to follow-up, and the median overall survival among patients was 39 months (range, 7-82 months). Conclusion: The findings provide support for the concept that, on the premise of standardized and valid management strategy, RTX containing regimens may be a safe option for use as the treatment of DLBCL patients combined with hepatitis B-related cirrhosis.

Medication therapy of high-dose methotrexate: An evidence-based practice guideline of the Division of Therapeutic Drug Monitoring, Chinese Pharmacological Society.

AIMS: A lot of medication risks related to high-dose methotrexate (HDMTX) therapy still remain to be identified and standardized. This study aims to establish an evidence-based practice guideline for individualized medication of HDMTX. METHODS: The practice guideline was launched by the Division of Therapeutic Drug Monitoring, Chinese Pharmacological Society. The guideline was developed following the WHO handbook for guideline development and the methodology of evidence-based medicine (EBM). The guideline was initially registered in the International Practice Guidelines Registry Platform (IPGRP-2017CN021). Systematic reviews were conducted to synthesize available evidence. A multicentre cross-sectional study was conducted using questionnaires to evaluate patients' perception and willingness concerning individualized medication of HDMTX. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to rate the quality of evidence and to grade the strength of recommendations. RESULTS: Multidisciplinary working groups were included in this guideline, including clinicians, pharmacists, methodologists, pharmacologists and pharmacoeconomic specialists. A total of 124 patients were involved to integrate patient values and preferences. Finally, the guideline presents 28 recommendations, regarding evaluation prior to administration (renal function, liver function, pleural effusion, comedications, genetic testing), pre-treatment and routine dosing regimen, therapeutic drug monitoring (necessity, method, timing, target concentration), leucovorin rescue (initial timing, dosage regimen and optimization), and management of toxicities. Of these, 12 are strong recommendations. CONCLUSIONS: We developed an evidence-based practice guideline with respect to HDMTX medication using a rigorous and multidisciplinary approach. This guideline provides comprehensive and practical recommendations involving the whole process of HDMTX administration to health care providers.

The Role of Genetic Polymorphisms in High-Dose Methotrexate Toxicity and Response in Hematological Malignancies: A Systematic Review and Meta-Analysis.

Objective: High-dose methotrexate (HDMTX) is a mainstay therapeutic agent for the treatment of diverse hematological malignancies, and it plays a significant role in interindividual variability regarding the pharmacokinetics and toxicity. The genetic association of HDMTX has been widely investigated, but the conflicting results have complicated the clinical utility. Therefore, this systematic review aims to determine the role of gene variants within the HDMTX pathway and to fill the gap between knowledge and clinical practice. Methods: Databases including EMBASE, PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and the Clinical Trials.gov were searched from inception to November 2020. We included twelve single-nucleotide polymorphisms (SNPs) within the HDMTX pathway, involving RFC1, SLCO1B1, ABCB1, FPGS, GGH, MTHFR, DHFR, TYMS, and ATIC. Meta-analysis was conducted by using Cochrane Collaboration Review Manager software 5.3. The odds ratios (ORs) or hazard ratios (HRs) with 95% confidence interval (95% CI) were analyzed to evaluate the associations between SNPs and clinical outcomes. This study was performed according to the PRISMA guideline. Results: In total, 34 studies with 4102 subjects were identified for the association analysis. Nine SNPs involving MTHFR, RFC1, ABCB1, SLCO1B1, TYMS, FPGS, and ATIC genes were investigated, while none of studies reported the polymorphisms of GGH and DHFR yet. Two SNPs were statistically associated with the increased risk of HDMTX toxicity: MTHFR 677C>T and hepatotoxicity (dominant, OR=1.52, 95% CI=1.03-2.23; recessive, OR=1.68, 95% CI=1.10-2.55; allelic, OR=1.41, 95% CI=1.01-1.97), mucositis (dominant, OR=2.11, 95% CI=1.31-3.41; allelic, OR=1.91, 95% CI=1.28-2.85), and renal toxicity (recessive, OR=3.54, 95% CI=1.81-6.90; allelic, OR=1.89, 95% CI=1.18-3.02); ABCB1 3435C>T and hepatotoxicity (dominant, OR=3.80, 95% CI=1.68-8.61), whereas a tendency toward the decreased risk of HDMTX toxicity was present in three SNPs: TYMS 2R>3R and mucositis (dominant, OR=0.66, 95% CI=0.47-0.94); RFC1 80A>G and hepatotoxicity (recessive, OR=0.35, 95% CI=0.16-0.76); and MTHFR 1298A>C and renal toxicity (allelic, OR=0.41, 95% CI=0.18-0.97). Since the data of prognosis outcomes was substantially lacking, current studies were underpowered to investigate the genetic association. Conclusions: We conclude that genotyping of MTHFR and/or ABCB1 polymorphisms prior to treatment, MTHFR 677C>T particularly, is likely to be potentially useful with the aim of tailoring HDMTX therapy and thus reducing toxicity in patients with hematological malignancies.

The implementation of a FIP guidance for COVID-19: insights from a nationwide survey.

BACKGROUND: The International Pharmaceutical Federation (FIP) has established an interim guidance of coronavirus disease 2019 (COVID-19) for pharmacists worldwide. The aim of this study was to identify the implementation of FIP guidance in China and provide applicable strategies for further actions. METHODS: A nationwide cross-sectional survey on Chinese pharmacists was distributed electronically through groups of WeChat between 9 December 2020 and 18 December 2020. The 29-item questionnaire for the survey was designed based on the FIP guidance and knowledge, attitudes, and practices (KAP) framework. RESULTS: A total of 237 responses from 237 pharmacists (69.20% females) were received. Most pharmacists (81.86%) participated in work related to COVID-19. Respondents referred to other guidelines or consensus more than they did to FIP guidance. Most participants were qualified for the knowledge-based questions regarding COVID-19 (67.51%), had positive attitudes towards pharmacists' roles and actions (61.18%), and were qualified in the practices of prevention measures, infection risk monitoring, and pharmacists' advice (50.63%). Several factors were revealed as having impact on pharmacists' KAP, such as the relevance of participating in work related to COVID-19, work entailments, and information source. CONCLUSIONS: The FIP guidance has a certain degree of dissemination and implementation in China, which can be improved through effective actions directed towards impact factors.

Optimal Management of the Public and Patients by Pharmacists in the Era of COVID-19: An Evidence-Based Review and Practical Recommendations.

Purpose: Currently, managing the public and patients during the COVID-19 pandemic is constituting a health care challenge worldwide. Patient-oriented management is of crucial importance to promote emergency preparedness and response. This study aims to formulate an integrated pharmacist management strategy of the public and patients and to provide evidence-based and practical references. Methods: Evidence-based review and practical analysis were utilized. First, PubMed, EMBASE and Chinese database were searched. Studies about patient management in major public health emergencies were included. Second, the Chinese experience of patient management was analyzed and identified. Finally, combining evidence-based and practical analysis, the pharmacist management strategy of the public and patients was researched and summarized. Results: Regarding the home quarantine period, pharmacist management services should include medication guidance, guidance on risk monitoring, sanitation measures education, health management guidance and psychological support. Regarding the outpatient visit period, pharmacists should participate in the control of in-hospital infections and provide physician-pharmacist joint clinic services, pharmacy clinic services, medication therapy management, medication consultation services, drug supply guarantee and drug dispensing services. Regarding the hospitalization period, pharmacist management services should include monitoring and evaluating the safety and efficacy of medications, providing strengthened care for special populations and other pharmaceutical care. For non-hospitalized or discharged patients, pharmacist management services should include formulating medication materials and establishing pharmacy management files for discharged patients. Conclusion: An evidence-based, patient-centered and entire-process-integrated pharmacist management strategy of the public and patients is established, which remedies the gaps in the existing patient management and can be implemented to support pharmacists' contributions to COVID-19 pandemic control.

Hospital pharmacists' pharmaceutical care for hospitalized patients with COVID-19: Recommendations and guidance from clinical experience.

OBJECTIVE: To discuss hospital pharmacists' role in providing pharmaceutical care for hospitalized patients with COVID-19 to promote patient care and management during the pandemic. METHOD: Based on the method of evidence-based pharmacy, clinical evidence of therapeutical drugs for COVID-19 were retrieved and summarized. Based on clinical experience Chinese hospital pharmacists gained from providing pharmaceutical care services during COVID-19 pandemic, taking COVID-19 hospitalized patients' needs into consideration, the methods and strategies hospital pharmacists shall use to provide pharmaceutical care were analyzed and summarized. RESULTS: Hospital pharmacists shall support pharmaceutical care services by participating in making evidence-based decisions for medication, monitoring and evaluation of medication safety and efficacy, providing strengthened care for special population and patients with combined underlying diseases, monitoring and management of convalescent plasma therapy, providing emotional counselling and psychological support, and providing scientific information about COVID-19 vaccines. CONCLUSION: The need of pharmaceutical care services in COVID-19 hospitalized patients during this pandemic was quite distinguished from the past. Hospital pharmacists shall join the collaborative multidisciplinary team to improve COVID-19 patients' outcome and reduce mortality, and to facilitate the pandemic control.

Pericarditis associated with cytarabine therapy for acute myelocytic leukemia: a case report.

BACKGROUND: The incidence of cytarabine-induced pericarditis is rare. So far, only a few cases have been reported worldwide. DESCRIPTION OF THE CASE: We are reporting a case of a 25-year-old male with acute myeloid leukemia (AML M2a) on chemotherapy who developed acute pericarditis after the administration of a cytarabine-containing regimen. The symptoms gradually improved after symptomatic treatment with steroids and other drugs. CONCLUSIONS: This case demonstrates that, although pericarditis induced by cytarabine is rare, early recognition of this potentially life-threatening complication and appropriate management will usually result in the patient's recovery.

Posaconazole-associated severe hyperbilirubinemia in acute myeloid leukemia following chemotherapy: A case report.

BACKGROUND: Posaconazole is a widely used azole antifungal agent, and posaconazole-associated severe hyperbilirubinemia is usually rare in clinical practice. We herein report a 58-year-old male with acute myeloid leukemia, who developed fungal infection following chemotherapy. CASE SUMMARY: After administration of posaconazole oral suspension, the patient developed severe hyperbilirubinemia and jaundice (Common Terminology Criteria for Adverse Events, CTCAE -Grade 3) with a serum total bilirubin (T-BIL) peak level of 170 µmol/L, alkaline phosphatase level of 739 U/L, alanine aminotransferase level of 99 U/L, and gamma-glutamyl transpeptidase level of 638 U/L. After posaconazole withdrawal and symptomatic treatment with liver-protective agents, the level of T-BIL and other laboratory data decreased gradually, and related symptoms disappeared. After medication analysis and literature review, we consider that the patient had a cholestatic type of posaconazole-induced liver injury, which was related to intracellular mitochondrial DNA damage. The case demonstrates that when patients with hematological malignancy develop severe infection following chemotherapy, combination of anti-infective drugs may contribute to a higher risk of severe drug-induced liver injury. CONCLUSION: This is the first thoroughly documented case report of posaconazole-associated severe hyperbilirubinemia. Therefore, in order to avoid severe adverse events, liver and renal function should be monitored closely before and during the administration of posaconazole.
