简介：AbstractBackground:Taxanes are an essential class of antineoplastic agents used to treat various cancers and are a fundamental cause of hypersensitivity reactions. In addition, other adverse events, such as bone marrow toxicity and peripheral neuropathy, can lead to chemotherapy discontinuation. This study aimed to evaluate the safety of taxanes in the real world.Methods:Taxane-associated adverse events were identified by the Medical Dictionary for Regulatory Activities Preferred Terms and analyzed and compared by mining the US Food and Drug Administration Adverse Event Reporting System pharmacovigilance database from January 2004 to December 2019. Reported adverse events, such as hypersensitivity reaction, bone marrow toxicity, and peripheral neuropathy, were analyzed with the following signal detection algorithms: reporting odds ratio (ROR), proportional reporting ratio (PRR), multi-item gamma Poisson shrinker (MGPS), Bayesian confidence propagation neural network (BCPNN), and logistic regression methods. Adverse outcome events and death outcome rates were compared between different taxane groups using Pearson’s χ2 test, whereas significance was determined at P < 0.05 with a 95% confidence interval (CI).Results:A total of 966 reports of hypersensitivity reactions, 1109 reports of bone marrow toxicity, and 1374 reports of peripheral neuropathy were analyzed. Compared with paclitaxel and docetaxel, bone marrow toxicity following the use of nab-paclitaxel had the highest ROR of 6.45 (95% two-sided CI, 6.05-6.88), PRR of 5.66, (χ2 = 4342.98), information component of 2.50 (95% one-sided CI = 2.34), and empirical Bayes geometric mean of 5.64 (95% one-sided CI = 5.34). Peripheral neuropathy following the use of nab-paclitaxel showed a higher ROR of 12.78 (95% two-sided CI, 11.55-14.14), PRR of 12.16 (χ2 = 4060.88), information component of 3.59 (95% one-sided CI = 3.25), and empirical Bayes geometric mean of 12.07 (95% one-sided CI = 11.09).Conclusions:The results showed that bone marrow toxicity and peripheral neuropathy were the major adverse events induced by taxanes. Nab-paclitaxel exhibited the highest potential for taxane-associated adverse events. Further research in the future is warranted to explain taxane-associated adverse effects in real-world circumstances.

简介：AbstractBackground:There have been few real-life dose-comparing studies on the efficacy and safety of secukinumab in Chinese patients with plaque psoriasis. We conducted a real-life cohort study to investigate the efficacy and safety of secukinumab 150 and 300 mg in Chinese patients with moderate-to-severe plaque psoriasis.Methods:A total of 106 patients with moderate-to-severe plaque psoriasis were included in this study. Patients received either secukinumab 150 mg or secukinumab 300 mg according to patients’ weights and severity of psoriasis. The treatment continued for at least 24 weeks. The efficacy was evaluated by improvement in the psoriasis area and severity index (PASI) scores. The safety was also analyzed.Results:Fifty-nine patients (55.7%) were treated with secukinumab 300 mg and 47 patients (44.3%) were treated with secukinumab 150 mg. After 12-week treatment, PASI75/90/100 responses were achieved in 100%, 97.8%, and 95.7% of patients, respectively, in secukinumab 150 mg group, and the efficacy was maintained to week 24. In secukinumab 300 mg group, PASI75/90/100 responses were achieved in 93.2%, 81.4%, and 76.3% of patients, respectively, at week 12. In this group, PASI75/90/100 responses reached 91.5%, 86.4%, and 79.9%, respectively, at week 24. Biologic-experienced patients had lower responses than biologic-naïve patients. Secukinumab 150 and 300 mg were well tolerated. Five patients discontinued treatment due to poor response, adverse event, or economic reasons.Conclusions:This real-life study demonstrated that high PASI 90 and PASI 100 responses were achieved in Chinese psoriasis patients receiving secukinumab 150 or 300 mg. Biologic-naïve was associated with better clinical efficacy.

简介：AbstractBackground:Benvitimod cream, a novel synthetic small molecule, was effective in treating mild-to-moderate plaque psoriasis. We conducted a phase III clinical trial to assess the efficacy and safety of benvitimod cream in patients with mild-to-moderate plaque psoriasis.Methods:We randomly assigned 686 patients (2:1:1) to receive 1% benvitimod cream, 0.005% calcipotriol ointment or placebo twice a day for 12 weeks. The primary efficacy end points were the percentage of patients with a 75% or greater reduction from baseline in the psoriasis area and severity index (PASI 75) score and with a score of 0 or 1 in static physician’s global assessment (sPGA) at week 12.Results:The results showed that 50.4% of patients in the benvitimod group achieved PASI 75, which was significantly higher than that in the calcipotriol (38.5%, P < 0.05) and placebo (13.9%, P < 0.05) groups. The proportion of patients achieving an sPGA score 0 or 1 was 66.3% in the benvitimod group and 63.9% in the calcipotriol group, which were both significantly higher than that in the placebo group (34%, P < 0.05). In the long-term follow-up study, 50.8% of patients experienced recurrence. After retreatment with 1% benvitimod, 73.3% of patients achieved an sPGA score of 0 or 1 again at week 52. Adverse events included application site irritation, follicular papules, and contact dermatitis. No systemic adverse reactions were reported.Conclusion:During this 12-week study, benvitimod cream was demonstrated with high effectiveness and safety in patients with mild-to-moderate plaque psoriasis.Trial Registration:Chinese Clinical Trial Registry (ChiCTR), ChiCTR-TRC-13003259; http://www.chictr.org.cn/showprojen. aspx?proj=6300.

简介：AbstractBackground:Psoriasis is a chronic inflammatory skin disease, affecting about 0.6% of the Chinese population. Many patients are not well controlled by conventional treatments, thus there is need for new treatment regimens. In this study, we assessed the efficacy and safety of secukinumab in Chinese patients with moderate to severe plaque psoriasis.Methods:This study was a 52-week, multicentre, randomized, double-blind, placebo-controlled, parallel-group, Phase 3 trial. A sub-population of study participants (≥18 years) of Chinese ethnicity were randomized to receive subcutaneous injections of 300 or 150 mg secukinumab, or placebo. The co-primary endpoints were psoriasis area severity index (PASI) 75 and Investigator’s Global Assessment (IGA) 0/1 at Week 12.Results:A total of 441 Chinese patients were enrolled in this study. Co-primary outcomes were achieved; 300 and 150 mg secukinumab were superior to placebo as shown in the proportion of patients that achieved PASI 75 (97.7% and 87.2% vs. 3.7%, respectively; P < 0.001), and IGA 0/1 (82.3% and 69.7% vs. 2.7%; P < 0.001) at Week 12. Treatment efficacy was maintained until Week 52. There was no increase in overall adverse events with secukinumab relative to placebo throughout the 52-week period. Conclusion: Secukinumab is highly effective and well tolerated in Chinese patients with moderate to severe plaque psoriasis.Trial Registration:ClinicalTrials.gov, NCT03066609; https://clinicaltrials.gov/ct2/show/record/NCT03066609.

简介：AbstractThe SARS-CoV-2 infection has brought a great challenge in prevention and control of the national epidemic of coronavirus disease 2019 (COVID-19) in China. During the COVID-19 epidemic, properly carrying out pre-examination and triage for patients with skin lesions and fever has become a practical problem encountered in hospitals for skin diseases and dermatology clinics in general hospitals. Some of the carriers of the SARS-CoV-2 and patients with COVID-19 in the early stage may not present with any symptoms of COVID-19, while certain other skin diseases can also cause fever. Therefore, to properly deal with the patients presenting at dermatology clinics, the Chinese Society of Dermatology organized experts to formulate principles and procedures for the pre-examination and triage of patients at dermatology clinics during the COVID-19 epidemic.

简介：AbstractBackground:The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor, which is critically involved in the pathogenesis of a variety of skin diseases. The aim of this study was to detect AhR and its downstream regulators including cytochrome P450 (CYP1A1), AhR nuclear translocation (ARNT), and aryl hydrocarbon receptor repressor (AhRR) in serum, peripheral blood mononuclear cells (PBMCs), and skin lesions in patients with atopic dermatitis (AD).Methods:Twenty-nine AD patients defined according to the criteria of Hanifin and Rajka and Chinese criteria of AD were included. Subjects without allergic and chronic diseases were recruited as controls. Patients and controls were selected from the dermatology outpatient clinic of Peking University People’s Hospital from August 1 to December 31 in 2018. Enzyme-linked immunosorbent assay was performed to detect serum AhR level. The mRNA of AhR, AhRR, ARNT, and CYP1A1 in PBMCs were measured by realtime quantitative polymerase chain reaction. AhR expression in skin lesions was measured by immunohistochemistry.Results:AhR was significantly higher expressed in serum (41.26 ± 4.52 vs. 33.73 ± 2.49 pmol/L, t = 6.507, P < 0.001) and skin lesions (0.191 ± 0.041 vs. 0.087 ± 0.017, t = 10.036, P < 0.001) of AD patients compared with those of controls. The mRNA levels of AhR (1.572 ± 0.392 vs. 1.000 ± 0.173, t= 6.819, P < 0.001), AhRR (2.402 ± 1.716 vs. 1.000 ± 0.788, t= 3.722, P < 0.001), CYP1A1 (2.258 ± 1.598 vs. 1.000 ± 0.796, t= 3.400, P = 0.002) in PBMCs of AD patients were higher compared with those of controls. The difference in mRNA levels of ARNT was not statistically significant between the patients and controls (1.383 ± 0.842 vs. 1.000 ± 0.586, t= 1.653, P = 0.105). AhR mRNA levels in PBMCs positively correlated with eczema area and severity index score and serum interleukin-6 levels.Conclusion:AhR and its downstream regulators were highly expressed in serum, PBMCs, and skin of AD patients, which might contribute to the pathogenesis of AD.
