RESUMO

Early December 2019 witnessed an international outbreak of a novel coronavirus (COVID 19) designated severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2). Since then, a number of therapeutic molecules have been explored to have potential efficacy against the SARS-Cov-2 per se or its sequelae. There are no Food and Drug Administration specific therapies approved so far; however, numerous drugs based on varying levels of evidence, in vitro studies and compassionate drug trials are being established as therapeutic agents, especially drugs approved for previous emergence of the severe acute respiratory syndrome (SARS-CoV-1) and Middle east respiratory syndrome coronavirus (MERS-Cov). Numerous active clinical trials for COVID-19 with more than 150 drugs and products are under study. Needless to say, many dermatological drugs are being employed to mitigate this pandemic threat. We aim to review drugs with potential against SARS-Cov-2 widely used in dermatology practice. Additionally, rampant and overzealous use of these drugs as well as introduction of new molecules might lead to emergence of adverse effects associated with these agents. Dermatologists must be on lookout for any cutaneous adverse effects of these drugs. J Drugs Dermatol. 2020;19(9):889-892. doi:10.36849/JDD.2020.5323.

RESUMO

BACKGROUND: HER2-positive metastatic breast cancer is incurable and new treatments are needed. Addition of atezolizumab to trastuzumab emtansine might potentiate anticancer immunity and enhance the HER2-targeted cytotoxic activity of trastuzumab emtansine. We aimed to test this combination in HER2-positive advanced breast cancer that had progressed after previous treatment with trastuzumab and a taxane. METHODS: The KATE2 study is a randomised, double-blind, placebo-controlled, phase 2 study at 68 centres from nine countries across Asia, Australia, North America, and western Europe. Eligible patients were adults (aged ≥18 years) with an Eastern Cooperative Oncology Group performance status of 0 or 1 and centrally confirmed, measurable, HER2-positive advanced breast cancer previously treated with trastuzumab and a taxane. Patients were randomly assigned (2:1) either trastuzumab emtansine (3·6 mg/kg of bodyweight) plus atezolizumab (1200 mg) or trastuzumab emtansine plus placebo; all study drugs were administered by intravenous infusion every 3 weeks. Randomisation was done via an interactive voice and web response system using a permuted block scheme (block size of six) and was stratified by PD-L1 status, world region, and liver metastases. Patients, investigators, and study team members were masked to treatment allocation. The primary endpoint was investigator-assessed progression-free survival in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT02924883, and the study has been completed. FINDINGS: Between Sept 26, 2016, and Aug 7, 2017, 330 patients were screened for the study, of whom 202 were randomly allocated either atezolizumab (n=133) or placebo (n=69). At the recommendation of the independent data monitoring committee, treatment assignment was unmasked on Dec 11, 2017, due to futility and the numerically higher frequency of adverse events among patients assigned atezolizumab. This date was set as the clinical cutoff for the primary analysis. Median follow-up was 8·5 months (IQR 6·1-11·5) for patients assigned atezolizumab and 8·4 months (5·3-11·1) for those assigned placebo. Median progression-free survival was 8·2 months (95% CI 5·8-10·7) for patients assigned atezolizumab versus 6·8 months (4·0-11·1) for those assigned placebo (stratified hazard ratio 0·82, 95% CI 0·55-1·23; p=0·33). The most common grade 3 or worse adverse events were thrombocytopenia (17 [13%] among 132 patients who received atezolizumab vs three [4%] among 68 who received placebo), increased aspartate aminotransferase (11 [8%] vs two [3%]), anaemia (seven [5%] vs 0), neutropenia (six [5%] vs three [4%]), and increased alanine aminotransferase (six [5%] vs two [3%]). Serious adverse events occurred in 43 (33%) of 132 patients who received atezolizumab and 13 (19%) of 68 patients who received placebo. One patient who received atezolizumab died due to a treatment-related adverse event (haemophagocytic syndrome). INTERPRETATION: Addition of atezolizumab to trastuzumab emtansine did not show a clinically meaningful improvement in progression-free survival and was associated with more adverse events. Further study of trastuzumab emtansine plus atezolizumab is warranted in a subpopulation of patients with PD-L1-positive, HER2-positive advanced breast cancer. FUNDING: F Hoffman-La Roche.

RESUMO

Immunotherapy represents a paradigm shift in oncology treatment. The goal of immunotherapy is to overcome immunosuppression induced by a tumour and its microenvironment, thereby allowing the immune system to target and kill cancer cells. The immunotherapy era began when the first immune checkpoint inhibitor, ipilimumab, was approved for use almost a decade ago. This therapeutic approach is associated with distinct types of response, including processes such as pseudoprogression (ie, increased tumour burden via radiology, which is not accompanied by clinical deterioration) and hyperprogression (ie, rapid progression of the disease as a result of immunotherapy). In this Review, we focus on therapeutic approaches for patients who progress on immunotherapy. We review the different types of clinical responses associated with immunotherapy and describe treatment options for this population.

RESUMO

RATIONALE: Low-dose mitotane has been widely used for many decades in patients with advanced adrenocortical carcinoma (ACC), which exhibited good safety profiles compared with the high-dose regimen. The clinical efficacy and toxicity of mitotane are closely related to its plasma concentration, and therapeutic drug monitoring (TDM) is recommended. Until now, no severe adverse drug reaction (ADR) related to the toxic plasma level after a short-term treatment of low-dose mitotane has been published. PATIENT CONCERNS: A 50-year-old Chinese female presented with severe neurological adverse events related to a toxic plasma levels of 42.8 mg/L after 4 months treatment of low-dose mitotane. DIAGNOSES: During the course of therapy, no other medication could cause neurological adverse events. Therefore, we suspected a high sensitivity to the side effect of mitotane related to a toxic plasma level. INTERVENTIONS: Treatment of mitotane was stopped. OUTCOMES: The trough plasma concentration of mitotane decreased to 18.7 mg/mL after one and a half months, and the neurological symptoms gradually improved after drug discontinuance. LESSONS: The present case provides the first report of severe neurological adverse events induced by the short-term use of low-dose mitotane for adjuvant treatment in a patient with ACC, indicating that potentially severe ADR can also occur when using low-dose regimen in the early stage of treatment. TDM and early recognition could result in a favorable outcome.

SUJETOS Y MÉTODOS: Estudio transversal y multicéntrico con la participación de 2 hospitales. Se incluyeron pacientes COVID-19 mayores de 18 años, con ingreso hospitalario y en tratamiento con LPV/r. Se realizó un cribado de las interacciones potenciales relacionadas con LPV/r y la medicación domiciliaria y hospitalaria. Se utilizó como base de datos de consulta Lexicomp® (Uptodate), HIV-drug interacctions y COVID-drug interacctions. RESULTADOS: Se incluyeron 361 pacientes con una media de edad de 62,77 ± 14,64 años, donde el 59,6% (n = 215) fueron hombres. El 62,3% (n=225) tuvieron una o más interacciones potenciales y el 26, 87% (n = 97) 2 o más. Las variables independientes asociadas a presentar ≥ 1 interacciones potenciales fueron la edad (> 65) (OR 1,95; IC 95% 1,06-3,59; P = 0,033), el ingreso en UCI (OR 9,22; IC 95% 1,98-42,93; P = 0,005), la enfermedad previa respiratoria (OR 2,90; IC 95% 1,15-7,36; P = 0,024), psiquiátrica (OR 4,14; IC 95% 1,36-12,61; P = 0,013), la dislipemia (OR 3,21; IC 95% 1,63-6,35; P = 0,001) y el número de fármacos prescrito (OR 4,33; IC 95% 2,40-7,81; P = 0,000). CONCLUSIÓN: La prevalencia de interacciones potenciales en paciente COVID-19 en tratamiento con LPV/r es elevada, comportándose como factores de riesgo asociados la edad (> 65), el ingreso en UCI, la enfermedad previa respiratoria, psiquiátrica y la dislipemia y el número de fármacos prescritos


OBJECTIVES: To determine the prevalence of potential interactions in COVID-19 patients receiving lopinavir/ritonavir (LPV/r). The secondary objective was to develop recommendations and identify the risk factors associated with presenting potential interactions with LPV/r. SUBJECTS AND METHODS: Cross-sectional and multicenter study with the participation of 2 hospitals. COVID-19 patients over 18 years of age, admitted to hospital and under treatment with LPV/r were included. A screening of potential interactions related to LPV/r and home and hospital medication was carried out. Lexicomp® (Uptodate), HIV-drug interactions and COVID-drug interactions were used as the query database. RESULTS: 361 patients with a mean age of 62.77 ± 14.64 years were included, where 59.6% (n = 215) were men. 62.3% (n = 225) had 1 or more potential interactions and 26, 87% (n = 97) 2 or more. The independent variables associated with presenting ≥ 1 potential interactions were age (> 65) (OR 1.95; 95% CI 1.06-3.59, P =.033), ICU admission (OR 9.22; CI 95% 1.98-42.93; P = .005), previous respiratory pathology (OR 2.90; 95% CI 1.15-7.36; P =.024), psychiatric (OR 4.14; 95 CI % 1.36-12.61; P =.013), dyslipidemia (OR 3.21; 95% CI 1.63-6.35; P = .001) and the number of drugs prescribed (OR 4.33; 95% CI 2.40-7.81; P =.000). CONCLUSION: The prevalence of potential interactions in COVD-19 patient undergoing treatment with LPV/r is high, with age (> 65), ICU admission, previous respiratory and psychiatric pathology, dyslipidemia and the number of prescribed drugs acting as risk factors

RESUMO

PURPOSE: To describe adverse drug reactions (ADRs) to carbamazepine (CBZ) and oxcarbazepine (OXC), including severe cutaneous ADRs, at a tertiary care hospital over a 10-year period. MATERIALS AND METHODS: The frequency and clinical features of ADRs caused by CBZ and OXC were analyzed using the pharmacovigilance database and spontaneous ADR reporting data of Yonsei University Severance Hospital & Dental Hospital (Seoul, Korea) from January 1, 2010 to January 31, 2020. RESULTS: Among 10419 cases prescribed CBZ and OXC, 204 ADR cases were reported. The incidences of ADRs were 1.8% and 2.2% for CBZ and OXC respectively, with no significant difference (p=0.169). The most common clinical presentations were skin disorders. Female patients had relatively more frequent ADRs than male patients. Although mild skin ADRs were more frequent with OXC, nervous system disorders, general disorders, and hepatobiliary disorders occurred more often with CBZ. There were six reports of severe cutaneous adverse reactions to CBZ, while OXC had none. Both CBZ and OXC caused ADRs at daily doses lower than the recommended initial dose. CONCLUSION: Due to lower incidence of severe ADRs with OXC than CBZ, we suggest OXC as a first-line prescription.

RESUMO

The geriatric population is growing and is the largest utilizer of emergency and critical care services; the emergency clinician should be comfortable in the management of the acutely ill geriatric patient. There are important physiologic changes in geriatric patients, which alters their clinical presentation and management. Age alone should not determine the prognosis for elderly patients. Premorbid functional status, frailty, and severity of illness should be considered carefully for the geriatric population. Emergency clinicians should have honest conversations about goals of care based not only a patient's clinical presentation but also the patient's values.

RESUMO

BACKGROUND: Whether prophylactic hyperthermic intraperitoneal chemotherapy (HIPEC) offers long-term survival benefit to patients with low-grade appendiceal mucinous neoplasms (LAMNs) after resection surgery is still under heated debate. The aim of the present meta-analysis is to investigate the comparative effectiveness and safety of prophylactic HIPEC regimens in LAMNs METHODS:: A systematic search of MEDLINE, EMBASE, PubMed, Web of Science, the Cochrane Central Register of Controlled Trials, International Clinical Trials Registry Platform (ICTRP), clinicaltrials.gov and controlledtrials.com will be performed. All published RCTs and quasi-RCTs through July 20, 2020 with language restricted in English will be included in this review study. Two reviewers will independently conduct the procedures of study identification, data collection, and methodological quality assessment. The primary outcomes are overall survival (OS) and disease-free survival (DFS). The secondary outcomes consist of peritonitis and sepsis, colonic fistula, chemotherapy-associated adverse events, and adhesive intestinal obstruction. The pooled odds ratios (ORs) or hazard ratios (HRs) and relative 95% confident intervals (CIs) of each outcome measurement will be calculated. EndNote X9 software will be applied to manage all citations. The Stata software version 14.0 and R x64 software version 3.5.1 will be employed for main statistical analyses. DISCUSSION: This study will employ a network meta-analysis to summarize direct and indirect evidence in the specific area to provide detailed individualized guidance on surgical management for LAMNs. REGISTRATION: This protocol was registered with the International Platform of Registered Systematic Review and Meta-Analysis Protocols (INPLASY) on 25 July 2020 (registration number INPLASY202070112).

RESUMO

A central issue in drug risk-benefit assessment is identifying frequencies of side effects in humans. Currently, frequencies are experimentally determined in randomised controlled clinical trials. We present a machine learning framework for computationally predicting frequencies of drug side effects. Our matrix decomposition algorithm learns latent signatures of drugs and side effects that are both reproducible and biologically interpretable. We show the usefulness of our approach on 759 structurally and therapeutically diverse drugs and 994 side effects from all human physiological systems. Our approach can be applied to any drug for which a small number of side effect frequencies have been identified, in order to predict the frequencies of further, yet unidentified, side effects. We show that our model is informative of the biology underlying drug activity: individual components of the drug signatures are related to the distinct anatomical categories of the drugs and to the specific drug routes of administration.

RESUMO

BACKGROUND: Stenotrophomonas maltophilia-induced pulmonary haemorrhage is considered a fatal infection among haematological patients. The outcome can be explained by the patients' immunity status and late diagnosis and treatment. CASE PRESENTATION: We present the rare case of successful outcome in a 61-year-old female who developed alveolar haemorrhage and acute respiratory distress syndrome 8 days after a chemotherapy session for her acute lymphoblastic leukaemia, in the context of secondary bone marrow aplasia. Stenotrophomonas maltophilia was isolated in sputum culture. The patient benefitted from early empirical treatment with colistin followed by trimethoprim/sulfamethoxazole, according to the antibiogram. Despite a severe initial clinical presentation in need of mechanical ventilation, neuromuscular blocking agents infusion, and ventilation in prone position, the patient had a favourable outcome and was discharged from intensive care after 26 days. CONCLUSIONS: Stenotrophomonas maltophilia severe pneumonia complicated with pulmonary haemorrhage is not always fatal in haematological patients. Empirical treatment of multidrug-resistant Stenotrophomonas maltophilia in an immunocompromised haematological patient presenting with hemoptysis should be taken into consideration.

RESUMO

BACKGROUND: Chronic and high dose opioid use may result in adverse events. We analyzed the risk associated with chronic and high dose opioid prescription in a Swiss population. METHODS: Using insurance claims data covering one-sixth of the Swiss population, we analyzed recurrent opioid prescriptions (≥2 opioid claims with at least 1 strong opioid claim) between 2006 and 2014. We calculated the cumulative dose in milligrams morphine equivalents (MED) and treatment duration. Excluded were single opioid claims, opioid use that was cancer treatment related, and opioid use in substitution programs. We assessed the association between the duration of opioid use, prescribed opioid dose, and benzodiazepine use with emergency department (ED) visits, urogenital and pulmonary infections, acute care hospitalization, and death at the end of the episode. RESULTS: In 63,642 recurrent opioid prescription episodes (acute 38%, subacute 7%, chronic 25.8%, very chronic (>360 days) episodes 29%) 18,336 ED visits, 30,209 infections, 19,375 hospitalizations, and 9,662 deaths occurred. The maximum daily MED dose was <20 mg in 15.8%, 20-<50 mg in 16.6%, 50-<100 mg in 21.6%, and ≥100 mg in 46%. Compared to acute episodes (<90 days), episode duration was an independent predictor of ED visits (chronic OR 1.09 (95% CI 1.03-1.15), very chronic (>360 days) OR 1.76 (1.67-1.86)) for adverse effects; infections (chronic OR 1.74 (1.66-1.82), very chronic 4.16 (3.95-4.37)), and hospitalization (chronic: OR 1.22 (1.16-1.29), very chronic OR 1.82 (1.73-1.93)). The risk of death decreased over time (very chronic OR 0.46 (0.43-0.50)). A dose dependent increased risk was observed for ED visits, hospitalization, and death (≥100mg daily MED OR 1.21 (1.13-1.29), OR 1.29 (1.21-1.38), and OR 1.67, 1.50-1.85, respectively). A concomitant use of benzodiazepines increased the odds for ED visits by 46% (OR 1.46, 1.41-1.52), infections by 44% (OR 1.44, 1.41-1.52), hospitalization by 12% (OR 1.12, 1.07-1.1), and death by 45% (OR 1.45, 1.37-1.53). CONCLUSION: The length of opioid use and higher prescribed morphine equivalent dose were independently associated with an increased risk for ED visits and hospitalizations. The risk for infections, ED visits, hospitalizations, and death also increased with concomitant benzodiazepine use.

RESUMO

BACKGROUND: Topotecan is currently the only drug approved in Europe in a second-line setting for the treatment of small-cell lung cancer. This study investigated whether the doublet of carboplatin plus etoposide was superior to topotecan as a second-line treatment in patients with sensitive relapsed small-cell lung cancer. METHODS: In this open-label, randomised, phase 3 trial done in 38 hospitals in France, we enrolled patients with histologically or cytologically confirmed advanced stage IV or locally relapsed small-cell lung cancer, who responded to first-line platinum plus etoposide treatment, but who had disease relapse or progression at least 90 days after completion of first-line treatment. Eligible patients were aged 18 years or older and had an Eastern Cooperative Oncology Group performance status 0-2. Enrolled patients were randomly assigned (1:1) to receive combination carboplatin plus etoposide (six cycles of intravenous carboplatin [area under the curve 5 mg/mL per min] on day 1 plus intravenous etoposide [100 mg/m2 from day 1 to day 3]) or oral topotecan (2·3 mg/m2 from day 1 to day 5, for six cycles). Randomisation was done using the minimisation method with biased-coin balancing for ECOG performance status, response to the first-line chemotherapy, and treatment centre. The primary endpoint was progression-free survival, which was centrally reviewed and analysed in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT02738346. FINDINGS: Between July 18, 2013, and July 2, 2018, we enrolled and randomly assigned 164 patients (82 in each study group). One patient from each group withdrew consent, therefore 162 patients (81 in each group) were included in the intention-to-treat population. With a median follow-up of 22·7 months (IQR 20·0-37·3), median progression-free survival was significantly longer in the combination chemotherapy group than in the topotecan group (4·7 months, 90% CI 3·9-5·5 vs 2·7 months, 2·3-3·2; stratified hazard ratio 0·57, 90% CI 0·41-0·73; p=0·0041). The most frequent grade 3-4 adverse events were neutropenia (18 [22%] of 81 patients in the topotecan group vs 11 [14%] of 81 patients in the combination chemotherapy group), thrombocytopenia (29 [36%] vs 25 [31%]), anaemia (17 [21%] vs 20 [25%]), febrile neutropenia (nine [11%] vs five [6%]), and asthenia (eight [10%] vs seven [9%]). Two treatment-related deaths occurred in the topotecan group (both were febrile neutropenia with sepsis) and no treatment-related deaths occurred in the combination group. INTERPRETATION: Our results suggest that carboplatin plus etoposide rechallenge can be considered as a reasonable second-line chemotherapy option for patients with sensitive relapsed small-cell lung cancer.

RESUMO

BACKGROUND: No standard treatment exists for advanced chordoma. Apatinib has been found to have promising efficacy and manageable adverse effects for the treatment of solid tumours. We aimed to investigate the safety and antitumour activity of apatinib in patients with advanced chordoma. METHODS: We did a single-arm, phase 2 study at one tertiary hospital in Shanghai, China. Eligible patients were aged 18-75 years, with histologically confirmed advanced chordoma that was unresectable or resectable only through demolitive surgery, who had previously received surgical treatment, with at least one measurable lesion according to the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, evidence of tumour progression on enhanced CT or MRI in the previous 6 months, and an Eastern Cooperative Oncology Group performance status of 0-2. Patients received oral 500 mg apatinib once daily until disease progression or unacceptable toxicity. The co-primary endpoints were progression-free survival and objective response rate according to RECIST 1.1 and Choi criteria by investigator assessment. Progression-free survival was assessed in the intention-to-treat population. Objective response rate was assessed in the per-protocol population, which included all enrolled patients who were compliant with the protocol and had at least one post-baseline assessment. Safety was analysed in all patients with complete safety data. This study is ongoing, but recruitment is complete. This study is registered with Chictr.org.cn, ChiCTR-OIC-17013586. FINDINGS: Between Aug 21, 2017, and May 31, 2019, we screened 32 patients, of whom 30 were enrolled. Median follow-up was 14·2 months (IQR 9·4-19·7). Of the 27 patients included in the per-protocol population, one patient (3·7%; 95% CI 0-11·3) achieved an objective response according to RECIST, and seven patients (25·9%; 8·3-43·6) achieved an objective response according to Choi criteria. Median progression-free survival was 18 months (95% CI 3-34) according to RECIST and 18 months (3-33) according to Choi criteria. The most common treatment-related grade 3 adverse events were hypertension (seven [24%] of 29 patients) and proteinuria (two [7%]). No treatment-related grade 4 adverse events or treatment-related deaths were observed. INTERPRETATION: To our knowledge, this is the first trial of apatinib for the treatment of advanced chordoma. Apatinib shows promising activity and manageable toxicity and thus might be an option for the treatment of advanced chordoma. FUNDING: None.

RESUMO

BACKGROUND/AIM: Some reports showed encouraging efficacy of immune checkpoint inhibitors among patients who experienced immune-related adverse events (irAEs). Thus, characterization of T-cell repertoire and immune signatures in peripheral blood mononuclear cells (PBMCs) and tumors before and after immune checkpoint inhibitors treatment should contribute to better understanding of irAE-provoked anticancer immune responses. MATERIALS AND METHODS: We applied expression analysis of immune-related genes and T-cell receptor sequencing in tumor and PBMCs from five patients with renal cell carcinoma before combined immunotherapy and at the onset of severe irAEs. RESULTS: We found that the cluster of differentiation 8 (CD8)/forkhead box P3(FOXP3), granzyme B(GZMB)/CD3, perforin 1(PRF1)/CD3 and programmed cell death 1(PD1)/CD8 expression ratios were significantly elevated in PBMCs at the onset of irAEs. In addition, we found expansion of certain T-cell clones in metastatic tissue after irAEs, which were already increased in peripheral blood at the onset of irAEs. CONCLUSION: irAE-provoked T-cells may also circulate and attack distant tumors, leading to durable response in patients with irAEs.

RESUMO

To explore the general characteristics of adverse drug reactions/adverse events(ADR/AE) in patients after using Shujin Jianyao Pills, and explore risk warning signals, this study analyzed 166 cases of ADR/AE reports of Shujin Jianyao Pills collected from 2005 to 2017 based on the National Center for ADR Monitoring spontaneous reporting system(SRS). And the descriptive statistical method was used to analyze general characteristics. The results showed that among the 166 ADR/AE cases, 106 cases were female patients, accounting for 63.86%. Middle-aged and elderly people aged 45 to 64 accounted for the largest proportion(82 cases, 49.40%), which were followed by elderly aged 65 and over(48 cases, 28.91%). ADR/AE involved a wide range of systems and organs, of which skin and its accessories were the most damaged(30 cases, 12.93%), which were followed by systemic damage(27 cases, 11.64%). The top 10 ADR/AE manifestations were rash(15 cases, 6.33%), nausea(14 cases, 5.91%), dizziness(14 cases, 5.91%), abdominal pain(12 cases, 5.06%), pruritus(11 cases, 4.64%), low back pain(11 cases, 4.64%), vomiting(10 cases, 4.22%), hepatocyte damage(9 cases, 3.80%), headache(9 cases, 3.80%), and diarrhea(7 cases, 2.95%). Bayesian confidence propagation neural network(BCPNN) was used to mine the ADR/AE risk early warning signal of Shujin Jianyao Pills, and the propensity score method was used to control the balance of confounding factors. The results suggested warning signs for nausea, diarrhea, rash, and dizziness, vomiting, abdominal pain, headache, liver cell damage. This study provides a basis for the post-marke-ting safety evaluation of Shujin Jianyao Pills, and can provide guidance for its rational clinical use and risk management.

RESUMO

A total of 1 392 reports on liver injury associated adverse drug reaction(LI-ADR) related to bone diseases were retrospectively analyzed based on national ADR monitoring system [18.75% of the patients used traditional Chinese medicine(TCM) alone and 68.68% used Western medicine alone]. This kind of cases accounted for 2.5% of all drug-related liver injury adverse reactions, ranking top ten of all drug categories. The number of reported cases and the proportion of serious cases showed an increasing trend from 2012 to 2016. The average age of the patients was(54.2±15.8) years old, and there was little difference in overall gender(male-female 1.04∶1). However, the number of female patients with rheumatoid arthritis was significantly higher than that of male patients(male-female 1∶2.6), while the number of male patients with gout was significantly higher than that of female patients(male-female 7.16∶1). The overall prognosis was good, with the recovery and improvement rate of 85.27%. The time from medication to liver injury varied due to different medicines. The median time to liver injury was 27 days in TCM alone group, later than 11 days in Western me-dicine alone group(P<0.05). Drugs for bone diseases have been one of the important categories for clinical drug-induced liver injury, and the number of reported cases on liver injury caused by drugs for bone diseases is increasing, so we should pay close attention to the safe and rational use of them. The LI-ADRs of male and female were different due to their different diseases, and the latency of adverse reactions in TCM group was generally longer than that in Western medicine group. In clinical medication, liver function should be monitored according to different diseases and characteristics of drugs to prevent the risk of liver injury.
