Multiple myeloma mesenchymal stromal cells: Contribution to myeloma bone disease and therapeutics

World Journal of Stem Cells 2014年第3期6卷 322-343页

Multiple myeloma is a hematological malignancy inwhich clonal plasma cells proliferate and accumulate within the bone marrow. The presence of osteolytic le-sions due to increased osteoclast(OC) activity and sup-pressed osteoblast(OB) function is characteristic of the disease. The bone marrow mesenchymal stromal cells(MSCs) play a critical role in multiple myeloma patho-physiology, greatly promoting the growth, survival, drug resistance and migration of myeloma cells. Here, we specifically discuss on the relative contribution of MSCs to the pathophysiology of osteolytic lesions in light of the current knowledge of the biology of my-eloma bone disease(MBD), together with the reported genomic, functional and gene expression differences between MSCs derived from myeloma patients(pMSCs) and their healthy counterparts(dMSCs). Being MSCs the progenitors of OBs, pMSCs primarily contribute to the pathogenesis of MBD because of their reduced osteogenic potential consequence of multiple OB inhibi-tory factors and direct interactions with myeloma cells in the bone marrow. Importantly, pMSCs also readily contribute to MBD by promoting OC formation and ac-tivity at various levels(i.e., increasing RANKL to OPG expression, augmenting secretion of activin A, uncou-pling ephrinB2-EphB4 signaling, and through augment-ed production of Wnt5a), thus further contributing to OB/OC uncoupling in osteolytic lesions. In this review, we also look over main signaling pathways involved in the osteogenic differentiation of MSCs and/or OB activity, highlighting amenable therapeutic targets; in parallel, the reported activity of bone-anabolic agents(at preclinical or clinical stage) targeting those signaling pathways is commented.

Cardiovascular disease (CVD) risk assessment is an important instrument to enhance the clinical decision in the daily practice as well as to improve the preventive health care promoting the transfer from the hospital to patient’s home. Due to its importance, clinical guidelines recommend the use of risk scores to predict the risk of a cardiovascular disease event. Therefore, there are several well known risk assessment tools, unfortunately they present some *** work addresses this problem with two different methodologies:1) combination of risk assessment tools based on fusion of Bayesian classifiers complemented with genetic algorithm optimization;2) personalization of risk assessment through the creation of groups of patients that maximize the performance of each risk assessment tool. This last approach is implemented based on subtractive clustering applied to a reduced-dimension *** methodologies were developed to short-term CVD risk prediction for patients with Acute Coronary Syndromes without ST segment eleva-tion (ACS-NSTEMI). Two different real patients’ datasets were considered to validate the developed strategies:1) Santa Cruz hospital, Portugal, N=460 patients;2)LeiriaPombal hospital Centre, Portugal, N=99 *** work improved the performance in relation to current risk assessment tools reaching maximum values of sensitivity, specificity and geometric mean of, respectively, 80.0%, 82.9%, 81.5%. Besides this enhancement, the proposed methodologies allow the incorporation of new risk factors, deal with missing risk factors and avoid the selection of a single tool to be applied in the daily clinical practice. In spite of these achievements, the CVD risk assessment (patient stratification) should be improved. The incorporation of new risk factors recognized as clinically significant, namely parameters derived from heart rate variability (HRV), is introduced in this work. HRV is a strong and independent predictor of mortality in patien

Pneumococcal disease in adult solid organ transplantation recipients

引用

World Journal of Clinical Infectious Diseases 2015年第1期5卷 1-10页

作者： Cristina Roca-Oporto María Eugenia Pachón-Ibaez Jerónimo Pachón Elisa Cordero Clinic Unit of Infectious Diseases Microbiology and Preventive Medicine Institute of Biomedicine of Seville University Hospital Virgen del Rocío/CSIC/University of Seville

In solid organ transplant(SOT) recipients, Streptococcus pneumoniae can cause substantial morbidityand mortality ranging from non-invasive to invasive diseases, including pneumonia, bacteremia, and meningitis, with a risk of invasive pneumococcal disease 12 times higher than that observed in non-immunocompromised patients. Moreover, pneumococcal infection has been related to graft dysfunction. Several factors have been involved in the risk of pneumococcal disease in SOT recipients, such as type of transplant, time since transplantation, influenza activity, and nasopharyngeal colonization. Pneumococcal vaccination is recommended for all SOT recipients with 23-valent pneumococcal polysaccharides vaccine. Although immunological rate response is appropriate, it is lower than in the rest of the population, decreases with time, and its clinical efficacy is variable. Booster strategy with 7-valent pneumococcal conjugate vaccine has not shown benefit in this population. despite its relevance, there are few studies focused on invasive pneumococcal disease in SOT recipients. Further studies addressing clinical, microbiological, and epidemiological data of pneumococcal disease in the transplant setting as well as new strategies for improving the protection of SOT recipients are warranted.

背景与目的通过意大利放射治疗和临床肿瘤学学会(Italian Association of Radiotherapy and Clinical Oncology, AIRO)的一项多中心回顾性研究,明确免疫疗法(immunotherapy, IT)和立体定向放疗(stereotactic radiotherapy,SRT)包括放射外科治疗(radiosurgery, RS)或大分割立体定向放疗(hypofractionated stereotactic radiotherapy, HFSRT)治疗非小细胞肺癌(non-small cell lung cancer, NSCLC)脑转移的疗效和毒性。方法对来自19个意大利中心接受SRT+IT的NSCLC伴脑转移患者进行分析,并与单独接受SRT的对照组患者进行比较。结果共纳入SRT+IT组100例和单独SRT组50例。接受SRT+IT的患者有更长的颅内局部无进展生存期(intracranial local progression-free survival, i LPFS)(经倾向性评分调整后,P=0.007)。在诊断为脑转移时接受IT合并有颅外进展的患者中(n=24),接受SRT后再进行IT与较好的总生存期(overall survival, OS)相关(P=0.037)。多因素分析显示组织学类型为非腺癌、卡氏体能状态(Karnofsky performance status,KPS)评分=70分以及接受HFSRT与显著减少的生存期相关(P值分别为0.019、0.017和0.007)。与SRT和IT治疗间隔>7天(n=10)相比,治疗间隔≤7天(n=90)与更长的OS相关(经倾向性评分调整后,P=0.008)。联合治疗耐受性良好。在放射性坏死方面,接受SRT+IT的患者与单独SRT的患者无显著差异。SRT和IT的治疗间隔对毒性发生率无影响。结论 SRT+IT是一种安全的联合治疗方法,与单独SRT相比,具有更长的i LPFS。
