Introduction:Hydroxychloroquine (HCQ) has received much attention in the treatment of coronavirus disease 2019 recently. However, it can cause irreversible vision loss. Few cases have been reported in pediatric patient with HCQ-related adverse reactions. Appropriate administration and early disease recognition are important for reducing the adverse drug reactions of HCQ.Patient concerns:We report a case of a 14-year-old Chinese girl who sought treatment for rapidly decreasing vision in the left eye over 3 days. The simulation results of the population pharmacokinetic model of HCQ revealed that the plasma concentration of HCQ abnormally increased before the visual acuity of the eye decreased.Diagnosis:She was diagnosed as HCQ related drug adverse reaction.Interventions:The daily dose of HCQ for this patient was adjusted from 100 mg/d to 50 mg/d.Outcomes:Follow-up for 6 months showed no more vision loss recurrence. However, the existing decreased visual acuity of the eye did not recover either.Conclusion:Although decreased visual acuity is an infrequent symptom, ophthalmologists should be aware of the possibility of HCQ concentration enrichment and consider minimizing HCQ use when a child with renal hypofunction seeks treatment for shortsightedness.  相似文献

Rosacea is a chronic inflammatory disease in face. Hydroxychloroquine (HCQ), an anti-malaria drug, was reported to have anti-inflammation activities. However, the role of HCQ on rosacea remains unclear. In this study, we revealed the potential molecular mechanism by which HCQ improved rosacea in rosacea-like mice and mast cells (MCs). Moreover, the effects of HCQ treatment for rosacea patients were investigated. In this study, we found HCQ ameliorated the rosacea-like phenotype and MCs infiltration. The elevated pro-inflammatory factors and mast cell protease were significantly inhibited by HCQ treatment in rosacea-like mice. In vitro, HCQ suppresses LL37-induced MCs activation in vitro, including the release of inflammatory factors, chemotaxis, degranulation and calcium influx. Moreover, HCQ attenuated LL37-mediated MCs activation partly via inhibiting KCa3.1-mediated calcium signaling. Thus, these evidences suggest HCQ ameliorated rosacea-like dermatitis may be by regulating immune response of MCs. Finally, the 8-week HCQ treatment exerted satisfactory therapeutic effects on erythema and inflammatory lesions of rosacea patients, indicating that it is a promising drug for rosacea in clinical treatment.  相似文献

Coronavirus disease 2019 (COVID-19) emerged in 2019 and rapidly became a global pandemic, infecting millions and killing hundreds of thousands. The disease altered the practices of hospitals, clinics, and patients. These changes have implications for advanced practice registered nurses (APRNs). APRNs must remain current on best practices for treatment and diagnosis of COVID-19 while being cognizant of changes to their scope of practice. As the pandemic continues, APRNs will remain on the front lines treating patients with COVID-19 while also caring for vulnerable populations within the community. To provide high-quality care, APRNs must use a multifaceted approach that heeds ongoing updates to evidence-based practice.  相似文献

目的检索与分析短期应用氯喹/羟氯喹(CQ/HCQ)可能导致的药品不良反应(ADR)及分析相关影响因素,为临床合理应用提供参考。方法通过检索PubMed、中国期刊全文数据库(CNKI)、万方数据库从建库至今CQ/HCQ引起的药品相关不良反应的个案报道的相关文献,设定单次服药至服药3个月内出现的ADR情况,分析CQ/HCQ可能引起的ADR及容易诱发ADR的相关因素,进行分析总结。结果共检索到文献1280篇,最终纳入42篇。其中心脏ADR共7篇10例,主要为心律失常,包括房室传导阻滞4例、Q-T间期延长4例;其中3例死亡,7例停药后恢复,服药1 g/d以上出现心脏毒性更快。视觉相关ADR文献4篇5例,其中应用CQ的1例,为单次用药后出现视力下降。HCQ的4例,出现黄斑病变1例,视物模糊1例,结膜充血2例。出现视物模糊与黄斑病变的患者停药后未恢复。皮肤ADR纳入21篇,严重的可引起Stevens-Johnson综合征2例,急性或泛发性脓疱病10例。其他严重ADR共10篇,主要表现为神经精神系统ADR。结论CQ/HCQ可引起严重ADR,对既往有心脏疾病、合并使用有相互作用的药物应进行严密监测,制定新型冠状病毒肺炎治疗的合理剂量,还应考虑患者疾病严重程度、肝肾功能情况,选择不同的药物与给药方案。  相似文献

Chronic ulcerative stomatitis (CUS) is an immune‐mediated disorder characterized by oral erosions and ulcers usually refractory to conventional treatments. The disease often involves middle‐aged and older women with painful lesions sometimes resembling those of erosive oral lichen planus (OLP). The most affected sites are the buccal mucosa, the gingiva and the tongue, but the skin is involved in 22.5% of cases. Histopathologic features in CUS are non‐specific and indistinguishable from those of OLP, with the exception of the presence of a mixed infiltrate composed of lymphocytes and plasma cells. Direct immunofluorescence (DIF) analysis reveals the presence of stratified epithelium‐specific antinuclear antibodies (SES‐ANA) in the lower third of the epithelium. The IgG antibodies detected on DIF are directed against the ?Np63α isoform of p63 expressed in the nuclei of the epithelial basal cells. A distinguishing feature of CUS is the low response to conventional corticosteroid therapy and the good outcome with hydroxychloroquine at the dosage of 200 mg/day or higher dosages. This paper presents a comprehensive review of CUS and is accompanied by a new case report (the 73rd case) and a proposal for updated diagnostic criteria.  相似文献

目的: 挖掘和评价新型冠状病毒肺炎治疗方案(试行第七版)中加入的药物"磷酸氯喹"和《上海市2019冠状病毒病综合救治专家共识》中推荐加入的"硫酸羟氯喹"上市后的安全信号,为临床合理用药提供参考。方法: 检索美国FDA不良事件报告系统(FDA adverse event reporting system,FAERS)数据库2004年1月1日-2019年12月31日收录以"氯喹"及"羟氯喹"为怀疑对象的不良事件(adverse drug events,ADEs)报告,提取排名前200位药物不良反应(adverse drug reaction,ADR)报告进行指定医疗事件(designated medical event,DME)筛选,采用报告比值比法(ROR)和比例报告比值比法(PRR)检测ADR信号,重点评估和比较出现DME的系统器官分类(SOC)中的安全信号,并对DME进行分析。结果: 提取FAERS数据库得到氯喹与羟氯喹ADEs报告数量分别为1 128例和29 639例;氯喹严重不良事件(serious adverse event,SAE)占比57.89%,羟氯喹占比26.60%。经DME筛选,共涉及7种SOC,其中眼部疾病与呼吸系统相关ADR中,羟氯喹检出的信号较多;皮肤和皮下组织类疾病,2种药物信号检出数量大致相等;心脏、血液及肝胆系统相关ADR中,信号主要集中在氯喹;耳部系统相关ADR中,信号检出较少。另外,氯喹检出的7种DME中尖端扭转型室速信号值最高,羟氯喹检出的4种DME中中毒性表皮坏死松解症信号值最高。结论: 基于真实世界的ADR信号检测有助于新冠疫情中氯喹与羟氯喹的安全性评价,降低临床用药风险。  相似文献

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-associated coronavirus disease 2019 (COVID-19) is primarily manifested as a respiratory tract infection, but may affect and cause complications in multiple organ systems (cardiovascular, gastrointestinal, kidneys, haematopoietic and immune systems), while no proven specific therapy exists. The challenges associated with COVID-19 are even greater for patients with light chain (AL) amyloidosis, a rare multisystemic disease affecting the heart, kidneys, liver, gastrointestinal and nervous system. Patients with AL amyloidosis may need to receive chemotherapy, which probably increases infection risk. Management of COVID-19 may be particularly challenging in patients with AL amyloidosis, who often present with cardiac dysfunction, nephrotic syndrome, neuropathy, low blood pressure and gastrointestinal symptoms. In addition, patients with AL amyloidosis may be more susceptible to toxicities of drugs used to manage COVID-19. Access to health care may be difficult or limited, diagnosis of AL amyloidosis may be delayed with detrimental consequences and treatment administration may need modification. Both patients and treating physicians need to adapt in a new reality.  相似文献
