Efficacy,immunogenicity, and safety of available vaccines in children on biologics: A systematic review and meta-analysis

Vaccinations are essential for preventing infectious diseases in children with chronic diseases as they have increased risk of infection from frequent use of biologics. Response to immunizations in this group is not well known.ObjectiveA systematic review was performed to evaluate three primary outcomes: efficacy; immunogenicity; and safety of vaccines in children with chronic conditions treated with biologics.MethodsThe protocol for our systematic review and meta-analysis was registered and published with PROSPERO. We searched electronic bibliographic databases for studies published from 2009 to 2019, focusing on vaccinations in children with chronic conditions treated with biologics.ResultsWe retrieved 532 records. Thirty-one full-text articles were selected, and 14 were included in the meta-analysis. No significant publication bias was found. Efficacy: limited data are available regarding the efficacy of vaccination, as most studies have focused on immunogenicity as surrogate outcome for efficacy. Immunogenicity: patients receiving anti-TNF-alpha therapy had a statistically significant risk of poor seroconversion (p = 0.028) and seroprotection by the serotype B influenza vaccine [inflammatory bowel disease (IBD) p = 0.013; juvenile idiopathic arthritis (JIA) p = 0.004]. We found adequate responses with H1N1 and H3N2 serotypes. Few studies existed for pneumococcal, hepatitis A virus, hepatitis B virus, varicella-zoster virus, Measles Mumps Rubella virus, and multiple vaccine administration. Safety: vaccine administration was not associated with serious side effects, but JIA patients on anti-TNF alpha therapy had a statistically significant risk of presenting with myalgia or arthralgia postinfluenza vaccine (p = 0.014).ConclusionsMore evidence concerning efficacy, immunogenicity, and safety of vaccinations is needed to guide physicians in the vaccine decision process for this pediatric population.     

艾拉莫德联合甲氨蝶呤治疗类风湿性关节炎的临床疗效及对患者骨代谢的影响

目的 探讨艾拉莫德联合甲氨蝶呤治疗类风湿性关节炎(RA)的临床效果及对患者骨代谢的影响。方法 将我院收治的86例RA患者随机分为两组各43例。对照组采用甲氨蝶呤治疗,观察组采用艾拉莫德联合甲氨蝶呤治疗。比较两组的临床疗效、骨代谢指标(β-CTX、 TPINP、 N-MID)及不良反应发生情况。结果 观察组治疗总有效率为95.35%,明显高于对照组的81.40%(P<0.05)。治疗后,两组的β-CTX水平降低, TPINP、 N-MID水平升高(P<0.05);观察组的β-CTX水平明显低于对照组, TPINP、 N-MID水平高于对照组(P<0.05)。两组的不良反应发生率(9.30%vs. 6.98%)比较差异无统计学意义(P>0.05)。结论 艾拉莫德联合甲氨蝶呤治疗RA效果显著,可有效改善患者的骨代谢,且安全性较高。     

输卵管妊娠治疗方式及其对未来生育影响的研究进展

输卵管妊娠是一种临床常见的妇科急腹症。输卵管妊娠如能在包块尚未破裂前早期诊断，其相关的病死率大大降低。输卵管妊娠的治疗方式有很多，无论哪种治疗方式，都会导致患者生育功能的下降。临床中对于有生育要求的患者，选择哪种治疗方式更好地保护患者的生育功能并减少并发症仍是有争议的话题。近年有学者做了大量研究比较输卵管妊娠不同治疗方式的并发症及其对患者未来生育前景的影响，甚至提出更新的治疗方式以弥补传统治疗方式的不足。现就输卵管妊娠的治疗方式、并发症及对未来生育的影响的研究进展进行综述。     

Effectiveness and safety of tocilizumab in monotherapy in biologic-naïve and non-naïve patients with rheumatoid arthritis in a real-world setting

ObjectiveTo evaluate the effectiveness and safety of tocilizumab (TCZ) monotherapy in biologic-naïve patients with rheumatoid arthritis (RA) versus patients with previous biologic exposure in a real-world setting.Materials and methodsNon-controlled clinical-trial, 32-week prospective multicenter study including RA patients with moderate-severe disease activity starting TCZ in monotherapy who had a prior inadequate response or were intolerant to methotrexate (MTX). Effectiveness according to EULAR response evaluated at 24-week and safety at 32-weekwere assessed.ResultsOf the 93 were enrolled of whom 84 (90%) were eligible for the effectiveness analysis. Biologic-naïve patients (n = 46, 54.8%) were younger (51.5 versus 57.9) with shorter disease duration (6.4 versus 13.3) but presented similar comorbidities in comparison with non-naïve patients. DAS28 remission was achieved in a higher percentage in the group of patients with prior biological treatment. 89 adverse events (AE) were recorded in 50 patients, most of them non-serious AE (non-SAE) (86.3%).ConclusionsIn a real world setting, TCZ exhibit similar effectiveness and safety in monotherapy in patients with RA regardless previous exposure to other biologic therapies. This study provides additional and valuable real-world findings on the use of TCZ in patients with RA.     

Metotrexato en pacientes con artritis reumatoide en España: subanálisis del proyecto AR Excellence

ObjectiveThe AR Excellence project evaluates clinical monitoring in patients with rheumatoid arthritis (RA) in Spain. The aim of the study was to analyze the use of methotrexate (MTX) in the AR Excellence cohort and to compare it with current recommendations.Patients and methodsWe collected data from RA patients who initiated treatment with MTX. They included demographics, dose and routes of administration, switching among them, highest dose in each route, combinations with other disease-modifying antirheumatic drugs (DMARDs), time to combination with another DMARD (either conventional or biological) and adverse events.ResultsSix hundred twenty-five patients with RA (mean age 55 years; 70.6% women) were included, with an average disease duration of 21 months. Ninety percent of the patients initiated treatment with MTX. Therapy was begun with a mean dose of 11 mg per week; this initial dose was increased in 58% of the individuals. The average time to reach the full dose of MTX (20 mg a week) was 6,67 months. Time to combination of MTX with another DMARD, either synthetic or biological, was 3 months. In all, 67.4% of the patients received oral MTX and the route was subcutaneous in 18.6%. In 12% of the cases, there was a change in the route of administration after a period of 6 months. In 544 patients, folate supplements were added to MTX; MTX-related adverse events were detected in 17.3% of the patients.ConclusionMTX is currently the pivotal treatment in RA. The subanalysis of the AR Excellence project demonstrates that MTX escalation to its full doses is not done with adequate speed. The subcutaneous route is used in a small proportion of patients.     

Acantholytic pityriasis rubra pilaris associated with topical use of imiquimod 5%: case report and literature review

Topical use of immune response modifiers, such as imiquimod, has increased in dermatology. Although its topical use is well tolerated, it may be associated with exacerbations of generalized cutaneous inflammatory diseases, possibly through the systemic circulation of pro-inflammatory cytokines. This report describes a case of development of pityriasis rubra pilaris, a rare erythematous-papulosquamous dermatosis, in a woman aged 60 years during treatment with imiquimod 5% cream for actinic keratosis. It evolved with erythrodermic conditions and palmoplantar keratoderma, presenting progressive clinical resolution after the introduction of methotrexate. The authors emphasize the importance of recognizing possible systemic reactions associated with the topical use of imiquimod.     

甲氨蝶呤皮下注射治疗应用与展望

【摘要】 研究表明，甲氨蝶呤皮下注射较口服途径可以获得更快、更好的吸收和更高的血药浓度以及较低的生物利用度变异度。在类风湿关节炎患者和银屑病患者，甲氨蝶呤皮下注射的疗效显著优于口服途径，并且胃肠道不良反应发生率更低。对于甲氨蝶呤口服疗效欠佳或者不耐受的患者，改为皮下注射后仍然可以获得较好的治疗反应。甲氨蝶呤皮下注射可以作为生物制剂使用前的治疗选择，可节省大量费用。总之，甲氨蝶呤皮下注射具有较好的临床应用前景。
